Food habits of seven frog species during mating periods were examined from gastric contents and species comparison were conducted. From 1041 frogs, elementary information on their food habits such as species and sizes of prey insects were reported and species difference and sex difference were discussed. Males of Tago's brown frogs (Rana tagoi ) and Shlegel's green tree frogs (Rhacophorus schlegelii ) foraged nothing during mating periods as previous reports, but males of the other five species did. Males of Japanese tree frogs( Hyla japonica) and Japanese stream frogs( Buergeria buergeri) were getting to forage towards the end of their mating periods. Especially, male black spotted pond frogs( Rana nigromaculata ) seemed to prefer larger insect than expected from their environment food resources, foraged well and gained their body weight during mating periods. These species differences seem to be caused mainly from their length of mating periods and their extent of site fidelity in mating periods.

Our aim is to produce ethanol efficiently by enzymatic saccharification coupled with ethanol fermentation using bamboo plant as a biomass. For this purpose, we examined pretreatment conditions of biomass for saccharification. At first bamboo plants were made into chips and then powders. When a distilled water with bamboo powder was 60-min autoclaved at 121 ℃, 0.75 M NaOH-alkalization treatment was performed at 80 ℃ , and saccharification was carried out by 0.33 g/ ℓ Acremonium cellulose at 45 ℃ , glucose was released at 5.7 g/ℓ after 96-h saccharification, which corresponded to 22.8 % on the basis of the the bamboo plant. When fermentation was carried out at 30 ℃ following 96-h saccharification of the pretreated bamboo plant using Acremonium cellulase, the inhibitory effect of glucose was considered to be reduced and ethanol was produced at 4.2 g/ℓ after 72-h fermentation, which corresponded to 50.8 % yield on the basis of the total amount of bamboo.

This study is a part of the fundamental researches of art appreciation education through meaningful dialogue in Japan. In late years appreciation education comes into the limelight. The class of art appreciation through meaningful dialogue in particular came to be carried out in each place of the whole country. However, understanding about an idea and the learning theory in the base of art appreciation through meaningful dialogue, and the reception process are not enough. I thought that it was tied to understanding and the spread more than a thing of art appreciation through meaningful dialogue to clarify Base of the idea and a reception process. In this report, I clarified the art appreciation education through meaningful dialogue in Japan is not a method brought about with" IKIRUTIKARA:Power to live" and Revision of the course of study, and not being a theory based on VTS and VTC, from a reception process in Japan of a text theory and the reception aesthetics, and from a reception process of learning theory of the constructivism, besides, from existence of the class practice that it can retroact to in the 1970s,

ニホンザルの内部寄生虫は、宿主であるニホンザル自体の疾病や死亡原因となるだけでなく、ヒト社会と生息域が重なることにより、公衆衛生上の問題として人獣共通感染症(zoonosis)の病原体ともなりうる。私たちは異なる生息地にすむ二つの野生ニホンザル群から糞を採取、分析、内部寄生虫保有率を比較した。調査対象は、人里に近い帝京科学大学に近接する山梨県大月市の野生ニホンザル群と、無人の宮城県金華山島の野生ニホンザル群である。大月群での内部寄生虫保有率は75%、金華山群では18,8%であり、主たる寄生虫は鞭虫(Trichuris sp.)であった。結果は、二つの群れの自然人為環境の違いが内部寄生虫保有率の違いに影響を与えていることを示唆する。

Management games are a comprehensive way for students of our Science and Engineering Department to experience the whole processes of management visually and experimentally. Management games set in the context of the manufacturing industry have been used over the last thirty years by more than 5 million business people in Japan but no comparable management games set in the service industry has been produced yet, despite the fact that the ratio of total supply of services is increasing year by year in Japan to 58.1 percent of total supplies in 2001 as shown in Input-Output Analysis data compiled and published by the Japanese government. The management disciplines of manufacturing businesses and services businesses are very different in ways such as : 1] No inventory exists in the service production process, such as an inventory of intermediate products and finished products, because services are real-time actions that bring customers benefits. 2] Any supplies and demands of services have to be met at a specific time, place and opportunity and sales and supply costs are incurred concurrently. 3] The supplier of services is "servant" to the customer and any additional supply of services is not possible at the same time as supplying services. 4] Customers of services have to be present at the service supply spots where the qualified technicians, tools and equipment are to be found. 5] Customers need not only enough money but also enough time in order to avail themselves of services. 6] Services are paid for in cash and no deferred payment is acceptable except by credit card. 7] The ratio of fixed investments in tools, equipment, buildings and land to total assets is greater than in the case of the manufacturing industry and the price of services is often massively discounted in order to promote sales. Services are categorized as one of two types --- "franchised" such as family restaurants and beauty and hair salons or "networked" such as railways and telecommunications. There are fundamental differences between the two and they cannot be dealt with in the same management game framework. The author of this article concentrated his efforts to produce management games of "franchised type services", specifically "Beauty & Hair Salon" Business Game.Beauty & Hair Salon Management Game starts with each player holding 1000 units of money and each begins to compete for customers in competitive markets, not by quoting prices but by appeal chips that symbolize the reputation of the salon's technicians and hair treatment products sales to customers. The results of one year's business operations are easily compiled into a statement of "profit and loss" and a "balance sheet", enabling players to develop strategic thinking skills for future business operations while playing the game.

Our objective in this study was to learn current conditions of physical exertion and fitness of performance of young people who will be reaching late twenties in 2020 or later and thus we looked at the relationship between cardiorespiratory endurance and amounts of physical exertion. [Subject]:Sixteen (16) subjects were randomly selected from seventy eight (78) healthy male students. [method]:As for examination methods, maximum oxygen consumption was measured using cardiopulmonary exercise testing (CPX) and a pedometer with accelerometer was employed to measure total energy expenditure (TEE). [Result]:Results showed that maximum oxygen consumption was significantly lower than the average value of results taken ten years earlier. Also it was confirmed that the maximum oxygen consumption has strong direct correlation with total energy expenditure (TEE). [conclusion]: This study points to a trend that decreased cardiorespiratory endurance among the current young people is deeply related, more so than other generations, to decreased amounts of daily physical exertion.
