The prototype of a library is analysed upon the facts that are generalized and recognized as commonsense. On the extension of the prototype, a digital library is considered. Ultimately the libraries' prototype should be steady at any time. A library which is being a digital library to which the best technology at that time applies, should function as the creator of the value by publishing, circulating, and re-production of the information resources.

Resistance performance of 3 G/T class coastal leisure boat is experimentally investigated at high speed ranges and the effect of a fin attached at hull side is studied together. Wave patterns are observed to make clear the relation between the resistance performances and the wave characteristics.

This paper presents the results of wave profile detection from video image using Mexican hat function. The Mexican hat function has been extensively used in the filed of signal processing to detect discontinuity in the images. The analysis was done on the numerical image and video images of waves which were taken in the circulating water channel. The results show that Mexican hat function is an excellent tool in the wave profile detection.

The objectives of this study were to analysis the nutrient cycles of agricultural by-products. The region, in which agricultural by-products are circulated for use within the agroecosystem for minimizing the input of artificial nutrients as well as generation of wastes, and where ecologically industrial diversity is formed, was defined as the regional agriculture focused on eco-industrial approach. Plan in stages for promoting ahead with the regional agriculture focused on eco-industrial approach is as follows: First of all, "The Consultation Body for Circulating & Using By-products" should be formed. Secondly, usage of agricultural by-products is identified to select the facilities of recycling and its location including the type and amount. Thirdly, the facilities for recycling of resources and infrastructure are installed. Finally, the facilities for recycling and resource circulation system within the area are efficiently managed.

There are several advantages to make use of a bridge pier for the tidal power generation. Current velocity increases near the pier, therefore the tidal power generation becomes more efficient because the power is proportional to the cubic of the current velocity. The pier is convenient for access and maintenance of the hydraulic turbine and the power unit. The project is now underway at the Ikitsuki Bridge in Tatsuno-Seto Strait of Nasasaki Prefecture, where the tidal current was measured by the bottom mount ADCP for almost one year. Model experiments for a Darrieus water turbine with two and three straight blades were carried out in the circulating water channel, in which the power coefficients of the turbine were obtained as a function of blade section and the attaching angle of a blade to the rotor. Those experimental results are discussed to obtain an optimum Darrieus turbine for tidal power generation.

Recently in the construction industry, industrial by-product admixtures like blast-furnace slag fine particles (BS henceforth) are being used as binding material, reducing the use of cement, and measures to reduce CO₂ emissions are being examined on various levels. However, the BS being used domestically varies depending on the origin of resources, and by circulating BS that is inappropriate to the KS standard, problems are occurring in terms of changes and declines in the quality of concrete which uses it. Therefore in this study the liquid densimeter principle was used to assess various BS fineness qualities; with 100 g/L fixed, a 1,000cc mass cylinder was most appropriate for assessing the quality of cement fineness.

The experimental manipulation of protooncogenes and their gene products is a valuable research tool for the study of human neoplasia. In this study, the recently identified human cervical cancer protooncogene (HccR-2) was expressed in transgenic mice under the control of the tetracycline regulatory system. Mice expressing the HccR-2 transgene showed an altered myeloid development characterized by an increased percentage of mature and band-form neutrophils in the peripheral blood, liver and spleen. This phenotype is similar to human chronic neutrophilic leukemia (CNL) in many ways, which is a rare chronic myeloproliferative disorder (CMD) that presents as a sustained leukocytosis of mature neutrophils with a few or no circulating immature granulocytes, an absence of peripheral blood monocytosis, basophilia, or eosinophilia, and an infiltration of neutrophils into the liver, spleen and kidney. Thus, the HccR-2 transgenic mouse model is imperative not only for investigating the biological properties of the HccR-2 protooncogene in vivo, but also for analyzing the mechanisms involved in the progression of CNL.

This paper describes the development of catamaran type powerboat applicable to leisure and transportation in the sea. Recently, the increasing prosperity of the leisure population has resulted in an increased popularity and need for recreational equipment such as water leisure powerboat. To satisfy the popularity and the need, catamaran type powerboat is developed applicable to leisure and simultaneously, as a means of tranportation for a short distance in the sea through the design using 3-Dimensional modeling method and experiments in circulating wate channel.

Inorganic binding material was made by recycled resource and its applicability as pile-filling material was examined. The result was that the material had same liquidity with the liquidity of OPC and high reactivity with site soil. According to dynamic/static loading tests by site test-construction, the inorganic binding material met both design bearing capacity and settlement. Since the inorganic binding material showed same or better performance than OPC, the utilization possibility of the inorganic binding material made of recycled resource as pile-filling material was verified.

This study is to analyze the difference by comparing the physical properties of general Portland cement (OPC) and low-heat Portland cement (LHC) in the market to develop low-heat cement manufacturing technology that can minimize the amount of limestone by using non-carbonate circulating resources as raw materials. To this end, the mortar is being reviewed by evaluating the properties of the mortar, such as slump, strength, durability, and thermal insulation properties, with a difference in the mixing ratio.
