The purpose of the dissertation is to offer basic data available for being conducive to application of a training program by comparatively analyzing the players' physical strength, the knee joint, a hip joint, power of the trunk joint and muscle power in order to study isokinetic strength and muscle power between short distance athletes and Taekwondo players. This study measured peak power, %Body weight peak power, always power, and %Body weight peak power targeting 8 male athletes and 8 male Taekwondo players who warmed up 10 minutes before from the test to reduce repulsion and unfamiliarity at the instrument. The power of the knee joint($60^{\circ}$/sec), muscle power($180^{\circ}$/sec), were measured by using HUNOM(U.S.A). As a result of the physical strength, statistically, short distance athletes were indicated to be better in muscle strength, muscular endurance than Taekwondo players, and there was no significant difference between flexibility, power, and muscular endurance. Although the short distance athletes were indicated to be better in right and left muscle strength of knee joint than Taekwondo player, there was no significant difference and Taekwonde players were indicated to be higher at the right and left muscle power than short distance athletes.

An artist, Oh Yun(1946~86)'s theory of people's art during his final period is summed up in his essay 'Expansion of Artistic Imagination and World' (1985). Emphasizing the mystic and traditional characteristics of Oh Yun's artistic oeuvre during his final period, some critics focus on Oh Yun's experience of medical treatment and shamanistic custom at Jin Do island, and his belief in Jeung San Do, the dao of Jeung-san, the Ruler of the Universe. However, they forget the practical intention and implication of his theory of art during his final period, which aimed to overcome the contradiction of revelation itself. Oh Yun's essay criticized the loss of artistic imagination and the ignorance of traditional culture that resulted from the elevation of science to a religion, and insisted that the stereotyped idealism, scientism and elitism in art should be overcome in order to recover the full reality in realism and to continue traditional cultures. The essay is comprised of 18 paragraphs. Oh Yun criticized monochromatic art, conceptual art, hyper-realistic art, objet d'art, and neo-dadaist art, saying that they were simply mechanical forms of modern art derived from scientism and a fetishistic lens culture. In addition, he criticized naturalism in art, which had continued as a tendency in the development of western art, for the same reason. He pointed out that even the world of realism had been diminished by elite stereotypes and diagrams. He declared the need to overcome the imitation of shells or stereotyped propaganda, and recover full realism, which seems to have started with a reflective examination of current problems in 'Reality and Utterance', in which he participated. Especially, he thought that universality and the extension of full realism could be achieved by building on the views of traditional cultures, which is meaningful. This logic is same as the theory of epic theatre that Bertolt Brecht(1898~1956) has developed under the ancient Greek masque and Pieter Bruegel the Elder(1525~69)'s story-like picture style. The universality of realism and the extension of acquisition to include incantation art, rather than move toward incantation art, is what Oh Yun intended to propose in 'Artistic Imagination'. This attitude is same as Bertoh Brecht's aesthetic viewpoint in the 1930s. But regrettably, Oh Yun's style wording, which seems covert and far-sighted, is often misunderstood as 'mysticism'. In the flow of people's art in the 1980s, Oh Yun was a traditionalist in a narrow sense, and an realist in a broad sense. However, his critical mind, which comprehends tradition and reality, was attempting to expand universality and extend full realism, and this attempt found many sympathizers and had an influence on the next generation of people's artists, such as "Levee" which is field-centered, to which we should pay attention. This means that while their works thought about 'tradition', we should be careful not to connect them with 'aesthetic conservatism' or 'classical art'. This is the why the meaning of Oh Yun's theory of art during his final period should be closely examined again.

The purposes of this study were to compare and analyze the world elite hurdler and the domestic hurdler 3-D kinematic and kinetic techniques about hurdling motion in the 110m hurdles. After analyzing variables in the 110m hurdle run the following conclusions were obtained; In a preparation phase, the domestic hurdler came out running more 0.13m then world elite hurdler from grounding to taking off in the height of center of gravity and the distance by 1.04m. In a flight phase, the domestic hurdler came out taking off 0.33m less then world elite hurdler from taking off to flight peak in the height of center of gravity and the distance by 1.63m. In a flight peak phase, domestic hurdler came out landing more 0.37m then world elite hurdler by 159m. More over, during the hurdling, the horizontal velocity of center of gravity came out decreasing from taking off to landing with domestic hurdler by 0.75m/s. the take off percentage and the landing percentage is 53:47. In a acceleration phase, domestic hurdler came out going slower 0.54m/s than world elite hurdler from landing in the horizontal velocity of center of gravity by 8.78m/s.

There has been growing debate over the current crisis of Korean journalism especially since 1997. While identifying primary causes as 'lack of credibility and public accountability,' however, this paper claims that self-regulation initiated by enlightened and professionalized journalists is a plausible solution. This paper thus pays attention to U.S. graduate journalism schools which provide specialized program about business/economic/financial news. For this, in identifying commonalities of the programs in terms of education goals, geographical/academic resources and course works, this study wanted to elicit meaningful implications for media education. It was suggested in conclusion that not only would Seoul be an ideal place for combining theoretical and practical training, but such programs in New York and Columbia university might be creatively applied to Korean journalism school. Finally, the author hopes that this review will be a good starting point for envisioning graduate level of journalism school in Korea.

This study was conducted to develop an SNP set that can be useful for marker-assisted breeding (MAB) in watermelon (Citrullus. lanatus L) using Genotyping-by-sequencing (GBS) analysis of 20 commercial elite watermelon inbreds. The result of GBS showed that 77% of approximately 1.1 billion raw reads were mapped on the watermelon genome with an average mapping region of about 4,000 Kb, which indicated genome coverage of 2.3%. After the filtering process, a total of 2,670 SNPs with an average depth of 31.57 and the PIC (Polymorphic Information Content) value of 0.1~0.38 for 20 elite inbreds were obtained. Among those SNPs, 55 SNPs (5 SNPs per chromosome that are equally distributed on each chromosome) were selected. For the understanding genetic relationship of 20 elite inbreds, PCA (Principal Component Analysis) was carried out with 55 SNPs, which resulted in the classification of inbreds into 4 groups based on PC1 (52%) and PC2 (11%), thus causing differentiation between the inbreds. A similar classification pattern for PCA was observed from hierarchical clustering analysis. The SNP set developed in this study has the potential for application to cultivar identification, F1 seed purity test, and marker-assisted backcross (MABC) not only for 20 elite inbreds but also for diverse resources for watermelon breeding.

As the nature of triathlons is competition in three successive sports, triathletes experience elevated levels of stress on the body that are absent in single-sport athletic events, and consequently there are more potential medical problems to prepare for. Triathletes can also experience problems such as hypothermia, heat illness, excessive exposure to ultraviolet radiation, musculoskeletal injuries and trauma, immunosuppression, and haemolysis. Depending on the potentiality of such above-listed problems occurring in any given race, race organizers will prepare preventative measures and treatments accordingly. Olympic distance is not the only triathlon racing distance. Sprints, which are normally around half the Olympic distance, are common distances, as well as Long (2 km swim, 80 km bike, 20 km run), Ironman (3.8 km swim, 180 km bike, 42 km run), and ultra-distance events varying in length. Races of longer duration normally result in a higher percentage of athletes experiencing the above-mentioned medical problems, as well as inducing additional health risks such as hyponatraemia. Minimizing the occurrences of serious health issues is possible through the following means: carefully preparing for the probable race-day weather conditions; proper management and organization of the race; preparing an extensive water-safety and ground-course safety plan; distributing necessary nutrition along the course; and stressing the importance for athletes to have proper knowledge concerning race nutrition, biomechanical technique, physical preparation, and utilization of safe equipment. While risks of competing in triathlon are many, the instances of such medical problems are not excessive, and the triathlon has a reputation of being a reasonably safe sport as long as athletes with high risk take added precautions.

The present study was performed to analyze and review the physical and immune responses to overtraining syndrome in humans. Overreaching refers to the initial phage of overtraining syndrome and has been known as a physical fatigue which is mainly from metabolic imbalance. It has been known that overtraining also results in a loss of adaptability which may lead to an attenuation of exercise performance, sleeping disorder, central fatigue, neurohormonal changes, difficulty recovery to physical stress, and immunological changes. Additionally, overtraining syndrome is characterized by persistent fatigue, poor performance in sport due to the prolonged and strenuous physical training. Also, previous studies reported that endurance athletes experienced a high incidence of URTI during intense training and the post training. And also, high-performance athletes reported that suppression of cell mediated and anti-body mediated immune function. NK cell numbers were also reduced in the period of overtraining syndrome. Major components of prevention and treatment for the overtraining syndrome are screening, education, and detraining. Furthermore, the combination of these prevention and treatment strategies will be much helpful. Therefore, the current review will be helpful for athletes and individuals who are at the risk of overtraining syndrome.

The general tendency of approach to Korean Design History has been focusing its primary interest on the grand story in relation to the problems of modernization in political, economical and social aspects of Korea. In the discourse of modernization, however, there are two sides immanent in the modernization: there is the formal, institutional and authoritative modernization developed inside the capitalistic mode of production and the informal, individual and cultural modernization manifested in the mode of everyday lives. Especially, despite the viewpoint of the latter being embossed as an alternative approach in various areas including the academic world of history since the collapse of socialism, the historical recognition of the phenomena of modern design by the Korean design historians is more like the 'history from the above' that exists at the level of the discourse outside the reality rather than the 'history from the below' that exists within the ordinary life. To grant a sense of balance in such frame of historical understanding, it requires the restructuring the design history of Korea through the cultural perspectives from having the representation of mundane lives realized by the voluntary design activity of the common people as research subjects. One of the methods to acquire an answer to such problem is decoding, in the manner of 'cultural history', the life-long domestic artifact made by Madame Yang, Gap Jo (currently 87 years of age) who is a model of typical Korean mother. Through the historical rumination on the traces of unpretentious lives of the people that has been buried under the grand narrative of the Korean Design History, a new era aimed for the historical prospect of Korean design as cultural history will be possible by excavating the petit yet multi-layered meaning of Korean designs.

The purpose of this study is to contribute the improvement of national welfare by presenting of pension welfare business of Korea and Japan. The reason why I take the management of Japan's pension accumulation as the object of comparative study is that the history of pension system of Japan is relatively longer than that of Korea. First of all, National Pension Fund comes into use for public sector, financial sector, and welfare sector, The scale of pension management for welfare sector is 50 small. Therefore, the study for welfare business investment reflecting the intentions of pension entries and pensioners is needs of times. This study defines the concept of welfare investment business and prospects welfare investment business of the future on the basis of Japanese experiences, and then suggests the direction of efficient propulsion of welfare investment business to the reasonable decision-makers. Especially this study redefine the concept of welfare investment business on the basis of pension entry's social benefits which are composed of pension entry's gains and pensioner's gain. Of course, welfare investment business has to be presupposed the stability of pension system and the continuous contribution to national economy. Thus, in order to efficiently perform welfare business, the policy-making for national welfare improvement has to be established after the good of business is set up like the results of this study.

This study aimed to identify the difference of scapular movements between tennis players with and without shoulder impingement syndrome(SIS) and to verify the effect of kinesiology taping applied to scapular. A total of 15 players were categorized in SIS group(n=7) and control(CON) group(n=8). The scapular movements evaluated using 3-dimensional motion analysis in the 5 events of the flat first serve before and after the application of taping. The male of SIS group(-7.31±1.19° and -5.28±1.08°, respectively) had tilted scapular more anteriorly compared to CON group(-0.98±5.38° and -0.44±3.52°, respectively) at the maximally humeral external rotation and the impact(Z=-2.309, p=.021 and Z=-2.309, p=.021, respectively). The scapular(-8.11±2.57°) of female in SIS group tilted more anteriorly than that of CON(-0.97±3.31°) group at the maximally humeral external rotation(Z=-2.121, p=.034). But the scapular movements had no statistical differences between before and after the application of taping.
