Mass mortality of the Manila clam, Ruditapes philippinarum has been reported all along the west and south coast of Korea for the past several years. As a pathogenic agent, Perkinsus sp., an endoparasitic protozoan has been identified in this study and believed to be responsible for the mass mortalities. Prevalence and infection intensity of Perkinsus sp. was investigated from a Manila clam population inhabiting at Komsoe Bay in the west coast where mass mortality of the clam has been reported. A total of 142 Manila clam, 50 oyster, Crassostrea gigas, 10 ark shell, Scapharca broughtonii, and 5 predatory gastropoda, Rapsna venosa were examined for the presence and the quantity of Perldnsus sp. Ray`s fluid thioglycollate medium method (FTM method) with modified Mackin`s infection intensity scale and Choi`s quantitative method were used in detecting and quantifying the parasite. All individuals of R. philippinarum examined in this study were infected with Perkinsus sp., indicaliag 100% prevalence white none of the oysters and the gastropods exhibited the parasite. Six to ten individual hypnospores of Perkinsus sp. were counted from the ark shells. The number of hypnospores in the clam tissues varied from 16,667 to 4,091,667, with a mean number of 1,077,628. Average infection intensity according to Mackin`s was 2.87, indicating a moderate infection. A negative correlation was observed between the number of Perkinsus sp. in the tissue and the condition index, a ratio tissue wet weight to shell cavity volume. The clam size and the infection intensity in terms of total number of parasites were positively correlated; the bigger clam, the heavier infection. Such high number of Perkinsus sp. counted in the clams could be enough to cause physiological disturbance of clams, such as retarded growth and reproduction. It is also believed that such a high infection leads mortality of the clam via continuous draining of the energy by metabolic activities and reproduction of the parasites. Correlation between the condition index and the infection intensity observed in this study supports this hypothesis.

N/A The apicomplexan parasite, Perkinsus sp., has been reported as a causative pathogen responsible for the mass mortality of the Manila clams, Ruditapes philippinarum in European countries as well as in Korea. Prevalence, infection intensity, histopathologic features and zoosporulation of Perkinsus found in the Manila clams distributed along the coast of Cheju Island were investigated in this study. Clams were collected from nine different beaches along the Cheju Island from May to July in 2000. Ray`s Fluid Thioglycollate Medium(RFTM) and Choi`s NaOH lysis methods were applied in the diagnosis and quantification of the Perkinsus infection. Prevalence, percentage infection of the parasite examined was 100% in Pyosun, 70% in Sungsan, 63% in Kumneong, 33% in Jongdalri, 21% in Iho, 17% in Moslpo, and 14% in Seogwipo. No Perkinsus was found in the clams collected from Kimnyong and Yongmeo-ri. Infection intensity as a number of Perkinsus cells per gram tissue wet weight(twwt), was 98,430 cells/g twwt in Pyosun, 78,553 cells/g twwt in Sungsan, 18,980 cells/g twwt in Kumneong, 4,290 cells/g twwt in Jongdalri, 1,527 cells/g twwt in Iho, 1,069 cells/g twwt in Moslpo, and 853 cells/g twwt in Seogwipo. Histological preparation of the infected tissues revealed trophozoites of Perkinsus sp., ranged from 5 to 10㎛, in diameter mostly distibuted in the digestive gland and the gill filaments. Zoospores were discharged from the hypnospore via discharging tube about 2 days after incubated in filtered and aerated seawater. In general, the prevalence and infection intensity of Perkinsus in Cheju Island were much lower than that reported from the western and southern coast of Korea.

Many Studies have demonstrated that the two hemispheres are functionally specialized in the majority of individuals, so that the left hemisphere regulates verbal-analytic cognitive abilities while the right hemisphere predominates in spatial-synthesis abilities. This research program have proceeded about the tendency of hemisphere specialization in sportsmen and variable subject classes in university. Sinagawa's questionnaire method was used as the instrument for this study . The results obtained were as follows: 1. In the physical education class(163subjects) 45.6%(male) and 41.6%(female) of the subjects were regarded as the left hemisphere dominant type, 47.4%(male) and 44.3%(female) of them were bilateral and 7%(male) and 14.2%(female) of them were regarded as left hemisphere dominant type. 2. In the representatives (mational players) group, very similar frequencies were shown except in the left hemisphere dominant type, whose percentile distributions appear as 12.9% in males and 12.6% in females. 3. Extremely higher frequency was shown in right hemisphere dominant type in the male students of medical science class : 63.5% of them were right, 24.9% were bilateral and 11.6% were left hemisphere dominant type. 4. The frequencies of the literature class also were shown very similar patterns with those of other female classes.

The purpose of this theses is to examine what effect of Jahn's ideas on German gymnstics. The French Revolution and the ambition of Napoleon's Expedition in Europe caused to infuse intersest in one race and patriotism for one's country in the hearts of the people of Europe. The ideology of the Revolution, that is, liberty, equality and philanthropy, led intellects of the European continent to strongly oppose to feudalism and autocratic monarchism, and to claim the establishment of liberal democracy from monarchs. They also played a leading role in carrying out the revolution during the period of 1848 to 1849. Jahn, a nationalist as well as an educator, first created German gymnastics which is called "Turnen" in 1811 in the suburbs of Berlin in an attempt to elevate hrs people to better status in their life and pursuits. In that contexy, the Turnen Movement hed spread all over Germany. The influence of Jahn's ideas on German gymnastic can be summarized as follows. FIRST, ESTABLISHMENT OF MODERN GERMAN PHYSICAL EDUCATION. The madern gymnastics of German originated by Guts Muths has been polished as modern gymnastics through the Turnen Movement by Jahn. SECONDLY, ESTABLISHMENT OF NATIONAL PHYSICAL EDUCATION Before popularization of Turnen Movement initiated by Jahn, the physical education of Germany was practiced only in a small group of nobility or philanthropium. With the establishment and popularization of Turnen, however, Turnen clubs were organized all over Germany, and it developed into a national-wide movement with the inauguration of Germany Gymnastic Association(Turnverein). The inclusion of gymnastic course into a regular school program contributed to establishing a system of the national physical education in Germany. THIRDLY, CHANGES OF EDUCATION SUBSTANCE. The gymnastics of philanthropismus was practiced and applied on the basis of individual life cycle with the emphasis of difference of individual quality. However, the education of Turnen characterizing the combination of philanthropismus and nationalism was conducted, pursuing cooperation in the community, individual perseverane and patriotism on the basis of the difference of individual quality. For example, it was focused on promotion of endurance with development of the upper part of the body by inventing a parallel bar and horizontal bar lathe then the development of skills of gymnastics.

Regarding the development of offshore natural gas field near Sakhalin Island which is an ice-infested area, this study aims to estimate the dynamic ice load for construction of offshore structures operating in this region. In this paper the design ice load and dynamic responses of a slender Arctic structure upon continuous ice movement are studied. Crushing after a certain elastic deformation is assumed as a primary failure mechanism at the contact zone between semi-infinite level ice edge and the face of structure. Dynamic interaction forces are calculated using a modified Korzhavin's equation and a two-dimensional ice-structure interaction model is adopted. To verify the numerical model, dynamic analysis is performed for one of the Baltic Sea channel markers whose response patterns were previously observed.

This paper was written for the importance of form and propotion in products design. Specially, we connected religious culture with products design. That is, the purpose of this study was to apply religious culture to products design as human companion. Therefore, we scientifically approach why and how do we have to consider seasonal form and propotion with product design. It should itself be seen as a counterproposal that products which is applied a religious culture can join the period in the end of the century and calm down man's despondent feeling.
