The Problem of sound radiation from rotational tire under the action of harmonic point forces is studied. The reaction on the vibratory response of the rotational tire is taken into account. The rotational tire is assumed to occupy the plane y = 0. The rotational tire material and the elastic foundation are assumed to be lossless and Bernoulli-Euler beam theory including a tension force (T), damping coefficient (C) and stiffness of foundation (k_s) will be employed. The non- dimensional sound power is derived through integration of the surface intensity distribution over the entire rotational tire. The expression for sound power is integrated numerically and the results examined as a function of wavenumber ratio (γ) and stiffness factor (ψ). Here, our purpose is to explain the response of sound power over a number of non-dimensional parameters describing tension, stiffness, damping and foundation stiffness.

As ED1 system come into use widely in administration, commerce and transportation, international trade carried out with documents traditionally is gradually being transformed into ' paperless trade' under such circumstances. By introducing ED1 system into Bills of Lading that are one of the most important documents in international trade using advanced information technology, ' The B/L Crisis' so called can be settled and the efficiency in international trade can be pursued. By the way such a new system has been proposed by CMI. This paper is a study on the functions of Electronic Bill of Lading proposed by CMI in comparison with those of traditional B/L, the problems in relation to implementation of Electronic Bill of Lading, and the acceptability of Electronic Bill of Lading in view of law and business practice. To sum up, though there is no problem in substituting paper B/L with Electronic Bill of Lading in view of its functions, it seems to be too early to grant the same legal effect to Electronic Bill of Lading as paper B/L owing to a defect in legislation. But there are constant efforts to accept Electronic Bill of Lading in international convention and business custom. Therefore it is forcasted that Electronic Bill of Lading will be introduced in the level of the management strategy and the survival of an enterprise in spite of the load of its cost and the difficulty of adaptation to new practice. As EDI is displayed to the best of its ability when it is generally implemented in all parts of transaction rather than partial implementation, it is probable that ED1 systematization of B/L will be realized in such level. In conclusion, although Electronic Bill of Lading has many questions to be settled and commercial practice is not easily altered, a keen request for the change of the current practical custom shall act most importantly on the introduction an settlement of new business custom.

Three assumptions of Martial arts in Orient were investigated int the context of philosophy. The aims of martial arts are divided into three parts. First, it helps one to develop one's morality in mind. Second, it enables one to cherish non-violence attitude and behaviour. Third, it leads one into the mysterious experience like the emancipation. Therefore, the martial arts in orient can be called philosophical arts. And also the western philosphical approaches seem to be possible, in the views of such Western philosphers as Aristoteles, Nietzche, Wertz, Descartes and Gallway. The difference between oriental and between martial arts cames from the linguistic dissimilarity. There is no basic problem between bath arts.

electron microscope for morphological changes of cytoplasmic organelles and with light microscope for detection of tubulin substances in the cytoplasm during estrous cycle. Experimental animals(weighting 200gm. female albino rats) divided into 4 groups by the estrous cycles. Ampullar oviducts of these animals were excised at each estrous cycles. The specimen was made into immunocytological reaction slides for detection of tubulin in the cytoplasm, and the other specimen were made to ultrathin section for electron microscopy. All of specimens were examined with light and electron microscope. The results obtained are as follows. 1. The tubulin substances in ciliated cells of oviducts revealed strong reactions during proestrus and estrus but weak reactions during metestus and diestrus. 2. After cis-Platin treatment, tubulin substances in the cytoplasm of oviductal ciliated cells showed weak stain reactions but at diestrus, moderate reactions were seen similar to that of the control group. 3. The cilia and basal bodies of ciliated cells of ampulla oviducts after cisplatin treatment were decreased in number at all stages of estrous cycle. 4. Ciliated cells in cis-Platin treated rat revealed hypertropies of mitochondria, atrophies of Golgi complex, decrease of polyribosomes and segmented cisternae of rough endoplasmic reticulum at proestrus, estrus and metestrus. It is consequently suggested that cis-Platin would induce inhibition of ciliogenesis in oviductal ciliated cells during estrous cycles.

As public facilities, public parking buildings are built with tremendous resource investments socio-nationally, and its outcomes affect general public's interests, much more near environments. Public parking building projects have been implemented focusing on how its initial costs could be economical. With literature reviews and expert interviews, elements affecting the construction type of public parking buildings were selected. The comprehensive constructability evaluation process which could be practical in the field is proposed through the classification of evaluation criteria influencing t#e constructability of public parking buildings and sequential evaluation process which modified the analytic hierarchical process. AHP was used as a basis of comprehensive constructability evaluation system, and vector nomalization and linear transformation in multi-criteria decision making technique were applied to each evaluation attributes to select the optimal alternative of public parking buildings.

In this paper, we have reported fundamental natural frequencies and damping ratios in the radial direction of various tires, from passenger car tires to truck-bus tires, under unconstrained condition. We have determined the radial directional modal parameters of tires, which are subjected to different levels of inflation pressure, by using frequency response function method. The results show that experimental conditions shift the natural frequency and damping ratio.

The Dyeing processing, which can be a low-cost and easily application to production field was investigated by using some bathochromic agent and dyestuffs. The Δ L values and dye up-takes of threated several fabrics were investigated according to the dye concentration and pH of dyebath. The results were as follows : 1. The selection of bathochromic agent acts as important factor for improvment of bathochromic property of fabrics. 2. The pH of dyebath has a little effect on bathochromic effect. 3. In case of one bath treatment, the bathochromic agent has little effect on the improving bathochromic property of treated fabric. 4. The efficiency order of bathochromic effect is DTY + fila.> CVY > DTY and fabric structure is also effect on the bathochromic property of the polyester fabric.

As an effort to revive our folk tradition, I am suggesting that our folk plays, especially those with a competitive nature, be turned into a sporting event which youths can enjoy, and which can be taught in every school. This will enable our students to gain a better understanding of our traditions and come to value and love them. Above all, an organization should be created that will play a central role in implementing this agenda. Second, this organization should lead in turning various folk plays into sporting events. Third, those events should be exciting competitions that will gain peoples attention. Fourth, to promote the spread of folk plays, they should be included in school curricula and trained physical educators should help spread these competitions in the schools. In addition, these events should be actively publicized through the press and other mass media. Lastly, this organization ought to take the lead in seeking assistance from the Office of Education to hold a variety of these sporting events. If these projects are carried out successfully, we will have a future in which folk plays are always with us in everyday life.
