▼ [Objective] Since 2011, large-scale disasters beyond assumptions of governments have occurred frequently throughout Japan, and hazard maps are in the process of change with law amendment etc. Evacuation regime is being improved on the premise of evacuation in a wider area, and the hazard maps are being renewed to assume the maximum class natural disaster. On the other hand, safe areas on the hazard maps will be decreased, consequently residents will need to determine safe places at emergency in their own judgment and evacuate. In this study, conducted the current situation survey of creation and disclosure of flood hazard maps and whether the contents are compatible with wide area evacuation, then extracted issues and proposed to solve using GIS. [Method] First of all researched the current situation of the flood hazard map. The survey target was all municipalities in Hokkaido, and we researched the creation situation, the disclosure situation, and the contents of the flood hazard maps. Also conducted a hearing survey on the current situation and issues of the hazard maps to the Hokkaido Government Office. Based on the results of the current situation survey, extracted "issues related to maintenance" such as creating and disclosing hazard maps, and "design issues" such as contents and displays described on the hazard maps. The design issues were discussed mainly based on easiness of comparison of maps for wide-area evacuation, namely, unity. Furthermore, we evaluated the current situation of the flood hazard maps of all the municipalities in Hokkaido against the extracted 'design issues.' Finally, we proposed a flood hard map that solved the issues using GIS, and summarized the creation workflow. [Result] Based on the results of the current situation survey, it was found that the actual number of municipalities creating and publishing flood hazard maps exceeded the number of grasped by the Hokkaido Government Office and the Ministry of Land, Infrastructure and Transport. Meanwhile, revealed that there are municipalities that have not created even though flood hazard maps are necessary. In addition there were some municipalities that have issues concerning disclosure situation. Also, it turned out that the design of flood hazard maps have wide variation. When evaluated the current situation on three factors, "cardinal direction", "scale of background map", and "color coding of supposed flooding depth", the dispersion of cardinal direction was particularly large. On the other hand, related to color coding of supposed flooding depth, there were also places where the risk of misreading was predicted. Furthermore, indications such as evacuation places and supposed inundation areas had been divided in administrative districts. Created a sample map around the Oasa area in Ebetsu city as an example aimed to solve these problems. This sample map was created using free GIS software, and geoprocessing data released by the government. Then organized and wrote down the work flow as a manual. With this, strived for promote the…

▼ White-fronted geese (Anser albifrons) forage on young leaves of wheat as well as rice grains in agricultural fields around Lake Miyajimanuma in Hokkaido, which is a migratory stopover site, causing wheat damage every spring. Behavioral characteristics of foraging patch selection of the geese have been studied, and fat reserve before leaving the stopover site has been clarified. The aim of this study was to elucidate the characteristics of field choice of the geese in relation to their fat level in order to solve wheat damage problems. Spatial and temporal patterns of field choice of the geese during the spring and fall staging periods in 2011-2012 were surveyed. Fat deposition level was estimated as the abdominal profile index, and pace rate was measured as the number of steps in 60 seconds for a randomly selected foraging goose in each field of rice stubble and wheat leaves. The distribution of geese was mainly in rice-stubble fields in early spring but changed to wheat fields in late spring. Fat deposition levels of the geese in wheat fields were significantly higher than those of geese in rice fields. No significant difference was found in numbers or pace rates of geese in wheat fields at different distances from the lake. The geese used rice fields near the lake in early spring but used rice fields far from the lake in late spring. The pace rate of geese in rice fields in late spring was significantly higher than that in early spring, and it was also higher in rice fields nearer to the lake. The results indicated that the density of rice grains was decreased in fields nearer the lake, the roost patch, especially in late spring. Geese with a high fat deposition level might forage in wheat patches due to the abundance of food density despite the low energy level of wheat leaves. On the other hand, geese with a low fat deposition level might forage in rice patches distant from the roost patch with a high predation risk because they give priority to fat accumulation. These results support the proposition that the wheat damage problem can be resolved by setting up an alternative feeding area of green manure crops to attract geese with high fat deposition levels.

本研究ではイネ葯培養効率を改善するため，水稲品種「キタアケ」と「きらら 397」を用い，二段階培養法で培養効率におよぼすカルス誘導期の培養環境（培養温度と照明）の影響を検討した．培養温度の実験ではカルス形成率は「キタアケ」で30℃区が25℃区に比べて有意に高く，「キタアケ」のカルス形成には 30℃が最適温度であることが明らかになった．一方，「きらら397」では30℃区が25℃区より高かったが，有意な差はなく，本研究で供試した2品種間ではカルス形成に対するカルス誘導期の培養温度の影響に差異が認められた．緑色植物再分化率では2品種とも25℃区が高くなった．葯当たり緑色植物再分化率は「キタアケ」では25℃区に比べ30℃区が高くなったが，「きらら397」ではほとんど差がなかった．一方，照明の実験ではカルス形成率は「キタアケ」の1回の実験のみで照明区よりも暗黒区で有意に高くなった．しかし，残りの実験では照明の有無で差は見られなかった．また，緑色植物再分化率と葯当たり緑色植物再分化率では2品種とも照明区と暗黒区にほとんど差が見られなかった．以上の結果から，カルス誘導期の培養温度は25℃～30℃の範囲が適することが示唆された．また，照明の有無では明確な結論が得られなかった．

▼ High pressure processing (HPP) is one of new technologies for food processing. HPP is expected to develop novel processed meat products and to shorten aging time of meat as wel l. The properties of meat for processing depend on species or anatomical locat ion of muscle. The effect of pressure treatment on the properties of different type of mus cles is not well known so far. The present study aims to reveal the difference of pressure effects on different type of muscle, such as white-type and red-type muscles of chicken and pork, by measuring water -holding capacity, pH, and texture of pressure-induced gel. Those properties of heat-induced gels were also investigated for comparison. Chicken breast muscle and leg muscle were used for whi te and red-type muscles, respectively. Porcine loin and tenderloin were also use for white and red-type muscles, respectively. Meat patty was prepared from each muscle by food processor with addition of 20% (w/w) of water and 1% or 2% of NaCl. The meat patty was pressurized at 100-300 MPa for 30 minutes or heated at 70℃ for 30 minutes. The water-holding capacity of heat-induced gel of chicken leg muscle with 1% NaCl was the lowest among the samples, though it was improved by increasing NaCl concentration to 2%. There were no obvious differences in water-holding capacity of heat-induced gel among other muscles. There were some pH changes in formed-gel after heat or pressure treatments, though it was difficult to explain the relation between pH change and water-holding capacity. The hardness of heat-induced gels was almost the same among the muscles, while the cohesiveness of chicken was larger than pork, and the heat-induced gel of chicken was more unbreakable compare to pork. Pressure-induced gels of all kinds of muscles showed very high water-holding capaci ty in the pressure range of 100-300 MPa. All of added water (20%) was retained in a gel. The hardness and cohesiveness of the gel increased wi th elevating pressure, while the adhesiveness of the gel decreased. These pressure-dependent rheological changes of gels were notable in pork than those in chicken. Pork loin was the most pressure-sensitive, and the changes in rheological parameters in th e gel with 2% NaCl was larger than that with 1% NaCl. There was some difference in pressure sensitivity of white- and red-type muscles among species. The present results indicate the difference in pressure-sensitivity among different type of muscles, and give useful information in application of HPP in meat processing.

▼ [Objective] Target region of Mongolia overgrazing, Brandt vole (Microtus brandti) modifies the soil by habitat disturbance. With the modification of the soil, I'm not like the modification to herbaceous plants and livestock. Aimed to reveal the workings of the ecosystem engineering by Brandt vole. [Method] 1. As for pasture, using the medium resolution satellite images of Earth Observation high frequency, we have analyzed the time series of changes in the amount of pasture. 2. The analysis is carried out for the selection of vole habitat, habitat for voles probability is higher in the show (around the river near the road around the gel) where the disturbance seen artificial. 3. As the target region of Mongolia over pastures, using a spectroradiometer proximity was measured electromagnetic waves reflected herb. 4. As the target region of Mongolia over pastures, conducted a survey of grassland vegetation ongoing, we have analyzed the changes of vegetation. [Result] 1. As for desert, Gobi region overgrazing-control plot, and analyzed for the amount of time-series change of pasture (NDVI), during the year 2011, the downward trend from 2003 to the amount of grass in the meadow area overgrazing was seen. 2. The analysis is carried out for the selection of vole habitat, habitat for voles probability is higher in the show (around the river near the road around the gel) where the disturbance seen artificial. 3. Target areas as overgrazing, was measured electromagnetic wave reflection of herbaceous plants. From the measured spectrum than the other, such as rice and sedge, Artemisia showed a high reflectance in the near infrared wavelength range (700nm). There are many Artemisia to overgrazing. Using high-resolution satellite images or aerial photographs, by evaluating the amount of pasture (NDVI) is the possibility of overestimation is considered normalized vegetation index. 4. Between 2010 and 2012, increasing the rate of vegetation cover in summer vole nest, the proportion of bare ground has decreased. Between 2011 and 2012, but there is a tendency to soil hardness will be hard, considering the variability of the data, in the nest of some soil hardness is low. In addition, the decrease in hardness due to variations in soil is often seen on the nest on the nest in the summer than the winter.

▼ Presently, the milk yield of Holsteins in Hokkaido is increasing, but their conception rate at the first service is decreasing and the calving interval is increasing. To improve reproductive performance, the factors causing the above must be clarified. The objectives of this research were to investigate the effects of angularity on herd life and reproductive performance and to investigate the effects of lactation persistency on reproductive performance. [The Effects of Angularity on Herd Life and Reproductive Performance in Holsteins] The effects of angular body shape of Holsteins on herd life and reproductive performance were investigated. The cattle group with high angularity score showed a significantly longer herd life and higher parity, 305 day corrected milk yields, and peak milk yields. No variations because of differences in angularity were observed for the number of days from calving to first service, conception rate for calving to first service, number of days to reach peak milk yield, days open, and services per conception. Based on the above, it was clarified that differences in angularity scores affected the herd life, parity, 305 day corrected milk yields, and peak milk yields, but did not affect the reproductive performance and number of days to reach peak milk yield. Further, high angularity score was found to be associated with increased parity and subsequent increases in the 305 day corrected milk yield and peak milk yield. Therefore, the cattle group with high angularity scores was considered to have high parity, 305 day corrected milk yield, peak milk yield, and long herd life. Thus, the above findings suggest that if cattle with high angularity scores were selected, then it is possible to populate the herd with cattle that have high parity, 305 day corrected milk yields, and long herd life. [The Effects of Lactation Persistency on Reproductive Performance in Holsteins] The effects of lactation persistency on reproductive performance in Holsteins were investigated. The cattle group with high lactation persistency showed significantly low number of days for calving to first service and days open. Further, as the lactation persistency increased, the parity significantly decreases. No variations because of differences in the lactation persistency were observed in the conception rate for calving to first service, services per conception, or 305 day corrected milk yields. On the basis of the above findings, it was shown that differences in lactation persistency affected the number of days for calving to first service, days open, and parity, but do not affect the conception rate for calving to first service, services per conception, or 305 day corrected milk yields. The above findings suggest that selecting cattle with high lactation persistency can achieve the following 1) delaying the day until peak milk yield is reached post calving and reducing the post-calving negative energy balance 2) quick recovery of ovary functions and the uterus post calving and improving the number of days for calving to…

本研究は、北海道で飼育される黒毛和種及びホルスタイン種の候補種雄牛について生産形質との関連性が認められているEDG1、LEP,、SCD1、FASN、NCAPG、DGAT1、FEZLの合計7つの遺伝子の多型の保有状況を調査した。各品種における各々の遺伝子の多型状況を確認し育種改良の際のDNAマーカーとしての有効性について検討を行った。本研究で調査したDNAマーカーはFEZL遺伝子を除いて、何れも非常に多型に富んでいた。しかし、黒毛和種においては、EDG1、LEP、NCAPGでは好ましい方の対立遺伝子が少なく、ホルスタイン種ではNCAPG、FEZLの好ましい対立遺伝子が少ないことから、両品種でのこれらの遺伝子の情報に基づく選抜の効果が期待された。特に、ホルスタイン種のFEZL遺伝子にっては、好ましい12Gの対立遺伝子が極めて少なく、積極的にこの対立遺伝子を保有する個体を選抜することが必要であると考えられた。

▼ I. Introduction As the number of dairy cattle per dairy farm increases in Hokkaido, an appropriate treatment of liquid feces and urine generated at cowsheds is essential. One of the facilities that treat such a liquid manure is a methane (anaerobic) fermentation-based biogas plant. It is the site where feces and urine is fermented under an anaerobic condition with a certain temperature. After fermentation, digested slurry left over is spread over fields as fertilizer. In the course of fermentation, organic matters are bio-decomposed into gas, which can be used as energy. There are many biogas plants operated in Europe. In those plants, the combined heat and power (CHP) system converts biogas into electricity to sell to power companies and households. Thermal energy is used under the local heating network. Biogas is also purified to use as fuel for natural gas vehicle. In Japan, Hokkaido leads the country's biogas plant operation. The form of biogas utilization is categorized into using heat converted by gas boiler, and using both heat and electricity generated by CHP system. In addition, a portable equipment has developed to purify, compress and replenish biogas, which has been tested to demonstrate that the purified gas can be used for natural gas vehicle and gas burners. Biogas can be treated by gas-boiler, CHP system and purification equipment. However, there are no previous reports that assess those three forms of biogas utilization by comparing their energy productive efficiency. In this paper, the authors have conducted a life cycle assessment of the productive and economic efficiency of biogas between the three forms of utilization (gas boiling, CHP system and purification), given that biogas is used in centralized biogas plants in cold regions. We particularly focused on the following objectives: (1) to establish a program in which biogas plant operation is simulated, calculate the energy balance of biogas under the cold climate of Hokkaido, and clarify the energy volume and energy productive efficiency of biogas utilized in each form; (2) to clarify the energy balance of biogas utilized in each form in consideration of the energy volume required for plant construction and maintenance, and conduct a life cycle assessment of each energy utilization system; (3) to conduct a life cycle assessment of biogas' economic efficiency given that the biogas energy replaces fossil energy, with consideration of costs for plant construction and maintenance; (4) to propose possible methods for utilizing biogas energy generated at centralized biogas plants in cold regions, toward future community development in Hokkaido. II. Form of Utilizing Biogas and Energy Balance Assessment A simulation model was created based on measurement data gathered from centralized biogas plants in operation. The effects of biogas utilization methods on energy balance during plant operation were compared quantitatively for cases in which a gas boiler, a CHP system or a purification system is used, to determine the most efficient biogas utilization…

▼ 1. Objective In late years, with economic growth of China, energy demands degree of the Chinese farm village area increases. On the other hand, a supply of the ene rg-y is short. The energy problem of the Chinese farm village area has an influence inside and outside China, and solution will be one of the necessary big problems in future. In such situation, in late years renewable energy becoming the topic is eco-friendly, and, a study and development advance from a merit to be able to produce energy. However, it is in an extremely severe state at this stage to take management profit, an problem to have low efficiency, and cost is high at this stage. The methane use technology has a long history than the use of other renewable energy, and the technique matures, too. The development process of the Chinese biogas system unfolds from three aspects, demand type of the energy, demand type of the habits, construction of the eco-home. The 21st century in particular begins, and the Chinese central government increases investment in biogas energy development year by year. In addition, the local government supports the introduction of the biogas plant of the farmhouse positively, too, and the biogas use in the farm village unfolds rapidly. Particularly, China has high diffusion rate of the individual model biogas plant. By the project to solve an energy problem of the Chinese farm village area by using a biogas plant, expectation is put to solving the energy problem of farm village area particularly the dairy farming area. In addition, the Chinese central government adds a concept of "the hygiene" to character of "the killing two birds with one stone" which means "the solution of environment and the energy problem" that a biogas system originally has and is going to open it in the character of "the killing three birds with one stone" which means "environment, energy, the hygiene". However, it is thought that there are many stopping facilities without being able to perform the continuous use even if the biogas use facilities of China build it. In addition, there is much unitary use of the degree that the biogas uses for the fuel of the kitchen of the farmhouse, and a policy to support the continuous and effective use of the biogas seems insufficiently. From such recognition, this article makes the actual situation of the biogas use of the farmhouse in China, Inner Mongolia clear and analyzes a merit and a demerit by the problem that occurred in a process of the biogas use promotion and the biogas use. Furthermore, compare and analyze the situation of the non-use farmhouse with the use farmhouse of the biogas plant, by economical and social and habits.It is in this way intended to consider an effect of the use of the biogas system. 2. Methods The Chinese biogas system is divided into large, middle, small size and individual model by the contents of quantity of outbreak and facilities of the biogas. It classify the size of the biogas with amount of production per day. When express it using V; biogas system large-scale V ≧ 300 m³,…

▼ Risk management is a continuous problem-solving process conforming to the PDCA cycle of 1) risk understanding, 2) risk analysis, 3) risk response and 4) response evaluation in order to prevent unexpected situations that arise from a variety of dangers. In this study, we report our examination of the current situation and problems associated with meal service provided at social welfare facilities, followed by our understanding of the risks, analyze those risks, construction of a response system, implementation and investigation of the risk response as well as our evaluation of the response. The purpose of this study was to demonstrate standards when a system of measures was introduced after risk management analysis of food service management, and clarify the possibility of its establishment both regionally and socially. 1. Method of risk management analysis（Extraction of important points for improvement）With regard to meal service program for nurseries, there were 10 important points for improvement including “Entrance of visitors,” “test results for ingredients,” “test of water quality,” and “designated storage space for ingredients”. For meal service at facilities for aged care, there were 6 important points for improvement including “specific menus for those needing particular care in cases of emergency,” “earthquakes,” and “storage of food for emergencies.” Note that with the categorization of measures, emphasis was placed on emergency response. The extraction of important points for improvement utilizing Customer Satisfaction (CS) analysis, as shown above, enabled risks to be visualized and the factors to be prioritized on-the-job to be recognized, and measures that could contribute to risk management in the provision of meal service were clarified. 2. Improved support program The improved support program, which included the important points for improvement, showed a transformation in actions with the nursery in A City, providing meal service for the subject infants in a better environment in terms of dietary education. In other words, reliable and safe lunches were provided, indicating the effectiveness of the program. 3. Introduction of the Japanese Food Guide Spinning Top for stocked foods The concept of the Japanese Food Guide Spinning Top for emergency stores was introduced and investigated. The results confirmed that even when the dietary balance guide is not employed, it is possible to put meals together. Therefore, if there is a method of indicating the quantities of stocked foods (SV:serving volume), it can be helpful in distributing relief supplies, based on the combination of stocked foods, and provide an effective tool.

▼ The recent dairy farms in Hokkaido have been increasing the amount of production milk yield by the scale expansion of production facilities and increase in the number of cows. A new machine and a new technology were adopted, and dependence on concentrate feeds became higher in the nourishment of the cow. Furthermore, the production system in dairy farms changed from grazing to housing to maintain stable milk production and stable milk quality. A figure of grazing style in dairy farms disappeared in Hokkaido day by day. It is raised as one of the main factors that it created such situation to have evaluated a production system in dairy farms focused attention an economic aspect. In such a background, it was suggested that we have to evaluate a dairy farming system totally. The evaluation by 5 indexes of economic balance, energy balance, environmental load, animal health and human satisfaction was carried out in Hamanaka Town. The results were suggested the possibility that a large amount of concentrate feeds leads to aggravation of animal health, and then a long-term plan in the town has been promoting from intensive to grazing dairy farming. Therefore, the aim of this study was to clarify checkpoints about the direction of grazing practical use and the fall of the feed cost to milk receipt ratio (F/M ratio), and to establish comprehensive dairy herd management and support techniques for the area based on regional characteristics. Total 53 dairy farms were chosen in Anebetsu district, Hamanaka Town, as eastern Hokkaido, Japan. Those farms have joined Japan Agricultural Cooperation (JA) of Hamanaka-cho since 1996. In chapter II, I compared the situation of the farm, which included productivity, economy, cow health and reproductive performance, between grazing and housing system. Furthermore, I divided into three groups by the levels of F/M ratio and analyzed the situation of the farm as described above. As a characteristic of grazing, the number of cows decreased, the rate of the agriculture income was high, and the rate of death and abolished cows to the number of farm cows decreased. As a characteristic of the falls of F/M ratio in the farm, the productivity was no change, the rate of the agriculture income was high, the rate of death and abolished cows decreased and the number of the somatic cell counts in bulk tank milk decreased. In chapter III, I studied the influence of the type of dairy farm from 1996 through 2010 on productivity, economy, or cow health. The type of farm was divided into four groups based on grazing or housing, which groups were 1) continued grazing, 2) continued housing, 3) switched from housing to grazing and 4) switched from grazing to hosing from 1996 through 2010. By the analysis, in the type of dairy farm which continued grazing and which switched from housing to grazing, the number of cows decreased, amount of production was maintained, the stocking density in the land area (the number of cows /ha) was appropriate, the economy was high or stable management, and the health condition of…

▼ 1. Purpose of Study Since the mid 1970s, the market showed tones of oversupply in milk and dairy products. Production adjustment, consumption rise, qualitative changeover and enhancement of competitiveness have become a critical issue. Conditions of operation in dairy farming are especially severe and managerial response is needed in a various way. One of such responses is a milk plant business. In this paper, firstly the nation-wide viable structure of milk plant and milk plants owned by farmers will be highlighted. Secondly, the importance of milk plants owned by farmers will be clarified using empirical analysis from a viewpoint of management economics as a managerial strategy of future milk plants. 2. Research Approach To clarify the critical issue of this research, three approaches were taken: the results of previous studies on milk plant were validated using statistical analysis at first. In the second place, nationwide existence of milk plants especially those owned by farmers were identified and analyzed through a quantitative study using questionnaire survey. In the third place, the milk plants owned by farmers were studied on managerial strategy by qualitative analysis or empirical analysis. 3. Research Results This research showed the following new findings: Firstly, based on the statistics and questionnaire survey, products of milk plants are drinking milk, milk beverage, fermented milk, butter, cheese, and ice cream including gelato. Concerning the structure of existence of milk plant owned by farmers, those in Hokkaido investigated by this research are in operation, while many other plants in Honshu suspended or closed their business. Secondly, from a detailed survey of actual conditions, it became clear that two types of management strategy: One is the milk plants owned by farmers producing raw milk in-house (a type to assist farmers) and the other is the milk plants owned by farmers purchasing raw milk from the outside (a type to contribute to the local industries). One example of the type to assist farmers is Ikeda Bokujo, a private limited company in Shiga Prefecture. Ikeda Bokujo is a diversified company running the following four businesses: a raw milk production, a gelatos shop “Kousou” at a municipal camping ground called “Aikyo-no-mori”, a farmer’s restaurant called “Kousouan”, and a camping ground. In view of their development stage, they started their business from feeding two cows for milking. The first stage of development was a scale expansion of feeding cows in 1970s. The second stage was an opening of Italian gelato shop processing and selling gelato in 1997 after they experienced excess production in 1980s. The third stage was after openings of the gelato shop and the farmer’s restaurant in 2003. In this process, diversifying business required business management skills and marketing ability, without which they cannot become what they are today. They have been expanding their business from the primary industry to the secondary, and the tertiary based on their safe products and local…

▼ The rheological properties and structure of the sucrose stearate molecular assemblies were investigated. Sucrose stearate is a one of the edible nonionic surfactants. The steady state viscosity and the dynamic modulus were measured as rheological properties of sucrose stearate aqueous solution. To investigate the microscopic structure of the molecular assemblies, a homemade small-angle light scat tering apparatus was build. The sample of sucrose stearate used in this study was an industrial grad, Ryoto Sugar Ester S-1670 (Mitsubishi Kagaku Foods Co. Ltd ., Tokyo, Japan) The outlook of the samples ( 1 to 8 wt%) was translucent or turbid from 20 to 47 ;however, it became transparent above 48℃ and their viscosity increased. The viscosity began to rise from 40℃ around aqueous solution at 3 to 8 wt%. The maximum viscosity value appeared a t 48℃ around. To obtain information on the structure of the molecular assembly, an SALS study was conducted. We can see strong scattering intensity at the low q region below the critical temperature (48℃); however, the scattering intensity was reduced above the critical temperature. We calculate the characteristic length of the density fluctuations from the scattering profile. The estimated values of ξ from the scattering profile were 300nm, 564nm and 862nm for 40℃ , 45℃ and 47℃ , respectively. These results indicates that relatively large molecular assemblies existed in the turbid phase; however, the size of the molecular assemblies decreased at approximately 48℃. In steady viscous flow measurements, viscosity was the maximum near 47℃. In measurement of frequency dependence of dynamic modulus of elasticity, the analysis in the Maxwell model was possible from 48℃ to 50℃. Scaling factor w as G_<tot> ∝ C^<1.9>. This result shows that stress under deformation occurred from the entanglement of the thread-like molecular assembly. According to reputation theory, when increase in concentration, worm-like micelles gets longer and the relaxation time gets longer. Since there is no strong dependence to the concentration relationship of concentration and slow mode relaxation time (τ_s), it is considered that the theory dose not work in this case. The mechanism of mechanical relaxation in this study can be explained by a phantom network model. It was revealed that Cox-Mertz rule has collapsed at around a critical shear rate, which was shear thinning beginning point in the flow curve. It is considered that the structure was destroyed by deforming at a faster rate than the relaxation time measured in the linear region, and there fore the stress has been reduced drastically. It is considered that structure was transition at 48℃ by a change in hydration behavior for SE18 aqueous solutions. Although the details of SE18 molecular assemblies below 48℃, it is considered that small structures such as spherical micelles are formed at around 30℃, and large aggregates had been formed in 40℃ or more.

▼ 【Objectives】The Tibetan antelope, also called chiru (Pantholops hodgsonii ), is an endemic species of Tibetan plateau. Each spring chiru females migrate several hundred kilometers from wintering sites to calving sites. During the migration antelopes have to cross the Qinghai-Tibet Railway (QTR) and Qinghai-Tibet Highway (QTH), which might cause negative consequences to animals. Therefore, the purpose of this study is to understand ecology and clarify the effect of QTR/QTH on the chiru.【Methods】1. To clarify the effect of QTR/QTH, the Animal Home Range using ARGOS PTT data was estimated. 2. In order to clarify the habitat selection of chiru, the home range of each individual animal was analyzed, wintering sites were classified and distribution model of the species was created. 3.Population census was conducted on transects in chiru habitat, the herd structure and herd size was investigated. Based on these results, the movement pattern of chiru around QTR/QTH was estimated.【Results】1. Analysis of the home range of chiru inhabiting neighboring to QTR/QTH area, showed that the width of the migration corridor was wider in those habitats. So far, artificial construction such as QTR/QTH influenced this effect on the seasonal migration behavior of chiru. 2. Analysis of the habitat selection of chiru has revealed three wintering sites in the Sanjiangyan area. Distance from the lake and altitude is most important factor for the habitat selection of wintering chiru. The selection of calving sites by breeding chiru is greatly affected by the distance from the lake. 3. During field observation only 27% of adult females were with offspring. The peak of migrating chiru in QTR/QTH is observed in 2nd of August, when number of migrating animals was accounted for approximately 30% of the total observed population. When crossing QTR/QTH, the herd of chiru is using the underpass in the form of detour from the shortest route, which is consistent with findings of satellite-based study.

▼ The Tibetan antelope (Pantholops hodgsonii), an endemic species of the Tibetan Plateau, listed as an endangered in IUCN, migrates over the long distances in order to give birth and only females do seasonal migration, which is the unique feature of this species. To identify the ecological drivers of the Tibetan antelope migration in terms of geographical characteristics, topographical variables of their ranges and the factors affecting the habitat selection within the seasons, the Argos transmitter satellite monitoring of the Tibetan antelope have been performed. The analysis included the LoCoH Hull method for the home range estimation and the Maximum Entropy analysis for the habitat selection modelling, made for the first time for this species. From August 2007 the location data provided the detailed spatial and temporal information. The analysis of the Argos system accuracy in given conditions revealed the less accurate and rarer signals during the winter season. Location errors were concentrated in the latitudinal direction, 67.52% of locations were accurate. The main pastures of the studied females were divided on three groups by their locations. The calving ground continued to be stable while wintering places changed easily. The necessity of the accession to the mutual migration route, as well as the similar timing of migration was shown. The Tibetan antelope used to start the migration in the middle of May and came back in the middle of August, however, due to the large amount of population delayed their migration next to the artificial barriers, the migration dates has shifted. The detailed route of females migration was not clear before this first time ever Argos monitoring. The annual habitation area varied from 2024 to 2908 km², and the wintering place located in a valley with the average home range of 441 km². The home ranges located near the artificial barriers (railway and a highway) had the shape, dependent on the linear construction and the migration corridor was wider in that area. The Maximum Entropy analysis showed the area, estimated as suitable for habitation, however, almost half of the most suitable area was out of the identified home ranges. The results suggest reducing the anthropogenic influence on the migration of Tibetan antelopes.

本研究は過熱水蒸気を用いたソバ種子の表面殺菌効果を微生物試験,機器分析,官能評価により確認するとともに,単一芽胞菌の殺菌効率を明らかにすることで過熱水蒸気表面殺菌技術の確立を試みた.ソバ種子への殺菌試験では玄ソバに比べ,抜き実への殺菌が効果的であり,特に250℃,10秒の殺菌では3 log CFU/g 以上の殺菌効果が得られた.品質に関しては,高温で長時間の過熱水蒸気処理を実施することで色,味,においについて,品質が劣化する傾向がみられたが,250℃,10秒の処理区においては劣化が少なかった.そのため,この処理区を原料として生そばを作製し,保存試験と官能評価を行った.その結果,未処理と比べて9日間の保存日数の向上がみられ,食味についてもほとんどの項目で未処理の生そばと有意な差は認められなかった.抜き実に存在する好気性芽胞形成菌を調べた結果,すべてがBacillus subtilisであった.さらにB. subtilisを7log CFU/枚となるように塗布した食品モデルを作製し,殺菌効率を調べた結果,250℃,10秒処理で検出限界以下に殺菌された.以上の結果から,過熱水蒸気による抜き実への殺菌は250℃,10秒の高温短時間処理により,抜き実の食味への影響が少なく,生残菌数を大きく低減させること,また表面殺菌処理が可能であることが明らかとなった.

抗菌薬が人医療および獣医療において広く用いられるのに伴い、薬剤耐性菌の出現と増加が公衆衛生学上の問題として世界的に懸念されている。また、薬剤耐性菌がもつ耐性遺伝子は、その多くが非病原性の環境細菌に由来するとみられていることから、現在蔓延している耐性遺伝子は、環境細菌から病原性細菌へと伝達されてから拡散したものと考えられている。これに加えて、合成抗菌薬に対する耐性遺伝子を染色体上にもつ細菌が報告されている点や、永久凍土層や洞窟などの隔離条件下からも耐性菌と耐性遺伝子が検出されている点から、耐性菌と耐性遺伝子は人為的な抗菌薬の使用による選択圧の有無に関わらず、自然環境中に存在しているものと予見されている。本研究では、上記の仮説を補完しうる知見を収集するため、絶対的抗菌薬非存在環境として南極のアイスコアを選択し、その中に含まれる耐性遺伝子の検出を目標とした。まず第１章では、氷サンプルの安全かつ十分なクリーニング方法を立ち上げるため、南氷洋およびオホーツク海で採材した海氷をサンプルとして、氷の洗浄および氷からのDNA抽出方法を検討した。また、海氷中の細菌叢を16S rDNAに基づく分類で特定し、その構成を両サンプル間で比較した。続いて第２章では、上記のクリーニング方法に基づいて実際の南極アイスコアを処理するとともに、含まれる微生物叢をメタゲノム解析によって網羅的に特定した。第3章では、海氷および南極アイスコア中から薬剤耐性遺伝子の検出を試み、検出した遺伝子について既知の遺伝子との比較を行なった。第1章における検討の結果、氷サンプルの洗浄方法が開発された。また、海氷に含まれる細菌叢を南氷洋とオホーツク海とで比較したところ、門レベルあるいは網レベルの広い分類ではおおむね似た傾向を示したが、科レベルや属レベルの詳細な解析で明確に菌叢が異なることがわかった。また、オホーツク海の海氷はバクテロイデス門の細菌を多く含むことが特徴であった。海氷を対象とする研究は数が少なく、また本実験で用いた採材地域でのサンプリングは過去に行なわれていないため、本研究の結果は海氷や低温環境中での細菌叢の構成に関する新たな知見を加えるものとなった。第2章では、1,670年前および2,860年前の南極アイスコアについて、細菌および真菌の構成をメタゲノム解析で特定した。グリーンランドなどのアイスコアを対象としたメタゲノム解析の既報と比べ、南極アイスコアのメタゲノム解析では遺伝子のヒット数が大幅に少ないことが特徴であったが、これは南極（ドームふじ基地）が周囲から隔絶された環境にあることが影響したものと考えられた。一方、2,860年前の氷については、デイノコッカス‐テルムス門の細菌が極端に多く検出された。本菌は極限環境微生物として知られており、ドームふじ基地における南極アイスコア中の微粒子の起源であるオーストラリアの砂漠環境にも分布しうる細菌であることから、これは細菌の付着した微粒子が当該アイスコア中に多量に含まれていた結果であると考えられた。アイスコアを対象としたメタゲノム解析は本研究が初報告であることから、今回得られた南極アイスコア固有の特性が今後の他のアイスコア研究の参考となることが期待される。第3章においては、南極アイスコアのうち約1,200～1,400年前の氷（サンプル名DF-63.5）から、sul2-strA-strBの耐性遺伝子クラスターを検出することに成功した。この遺伝子群は現代でも非常に広範な種類の細菌が保有していることから、この遺伝子は古くから環境細菌が保有しており、その細菌が南極の氷にトラップされていたことが予想された。また、DF-63.5から得られた遺伝子の塩基配列が現代の当該遺伝子と相同的であったこと、およびこの遺伝子群を組み込んだ形質転換株（大腸菌）が抗菌薬耐性を発現したことから、今回得られた耐性遺伝子群は現代の相同遺伝子と極めて近縁であることが確認された。さらに、耐性遺伝子が単体ではなくクラスターとして検出されたことから、人為的な抗菌薬使用が無い環境においても、薬剤耐性遺伝子がまとまって細菌間を移動していることが考えられた。これらに加え、sul2遺伝子が合成抗菌薬であるサルファ剤に対する耐性遺伝子であることから、合成抗菌薬の発明以前にもその耐性遺伝子が存在しうることが改めて示された。以上の成績から、抗菌薬の非存在下においても薬剤耐性遺伝子が存在することが証明された。これまでに永久凍土層や南極表層の雪などからの耐性菌および耐性遺伝子の検出報告はあるが、南極アイスコアという完全に外界から隔絶された環境からの報告は今回が初めてである。抗菌薬耐性菌の出現と蔓延を予見するためには、それらの起源や環境中における動態を明らかにすることが必要であることから、本研究の結果は抗菌薬の選択圧非存在下における耐性遺伝子の存在を証明したものであり、新たな薬剤耐性菌対策の構築に有用な知見を提供した。

▼ [Objectives] Mesquite(Prosopis juliflora) is a shrub or small tree in the Fabaceae family. It is native to South America. Mesquite was introduced into Kassala state, eastern Sudan by the Food and Agriculture Organization (FAO), an international organization, for the plant's high usability as a stabilization of sand dyne, feed for livestock, and building material. However Mesquite has invaded beyond the place where it is managed artificially. Mesquite adapts to arid and semi—arid land through various living strategy, with there is hardly any precipitation in dry season. Mesquite expands to other areas through river water. Additionally it is suggested that expansion of Mesquite to other areas by livestock. Based on these situations, there are two objectives in this study. 1. To clarify the difference of Mesquite vegetation activity between rainy season and dry season; 2. To clarify Mesquite without effect of river water on hill, and the place far from the river that was expanded by livestock. [Methods] The study site is Atbara river basin between Kassala state and A1 Qadarif state in eastern Sudan. ( 15° 3' 37. 40"N, 35 ° 58' 3. 15"E ) and we calculate vegetation activity by MSAVI2(The modified soil-adjusted vegetation index) from the two satellite images. The one is LANDSAT image from 1986 to 2014 for analyzing area of Mesquite. The other one is Terra MODIS image from 2000 to 2012 for analyzing response of Mesquite to precipitation. We carried out the field investigation in December 2013. In the field we measured stomatal conductance and spectral feature of Mesquite and trees of original species for comparing difference between them. We collected satellite tracking data of livestock for analyzing home range by LoCoH model. Also stocking of the livestock and interview with the herdsman regarding impression of Mesquite. Finally we collected and analyzed 10 points of Mesquite on hill by ASTER GDEM 30m elevation data. [Result] The Mesquite adapted to arid and semi-arid land by inhibiting stomatal conductance and maintaining high vegetation activity. The area of Mesquite expanded 12. 4 times from 1986 to 2005 and grow thick at inside of the curve of river. From 2005 to 2014, the area of Mesquite decreased. This is because of the Mesquite removal policy by Sudanese government started in June 2006. We also confirmed that local people in Kassala removed Mesquite. Response of Mesquite activity by precipitation from 2000 to 2012, before precipitation peak is a positive correlation of time lag 2 months with a significance level of 1%. On the other hand after precipitation peak is positive correlation of time lag 6 months with a significance level of 1%. From this result, Mesquite is repeated seasonal variation. According to the result of the LoCoH model of livestock, they accessed to the Atbara river and stayed long. There is a possibility that the livestock graze Mesquite seeds. We confirmed that livestock graze on hill and their droppings included Mesquite seeds. Moreover there were 10 Mesquite points on hill. This is a…
