Zhuangzi contends that one of the reasons to cause life difficulties is mistaking the truth of cosmos and the existence meaning of human. There is no difference of value between the existence of human and universal creatures. However, "human mind" can not being peaceful because of " ChengXin(成心)" causes the difference of right and wrong. Zhuangzi contends the ideal world is "ZhiDe zhi World(至德之世)" of unmoved mind. Because of the value of "RenYiDaoDe(仁義道德)" in politics, the status of ideal existence of human and creatures is destroyed, i.e., disturbing the status of peaceful mind. This is also a reason of life difficulties. Zhuangzi contends the reasonable relationship of human and creatures is to recognize creatures as creatures, and therefore, there is no difference of value between creatures. Additionally, one shall understand the concept of "universal creatures are the same(萬物?一)" is based on the fact of continuous change of universal creatures. The socalled concept of "universal creatures are the same(萬物?一)" in Zhuangzi's thought is based on three dimensions: one is the materials of forming universal creatures; one is the same meaning of "Hisn" between human and creatures, and universal creatures are continuously changing. Therefore, one shall get a clear understanding of the nature of things, and one may treat the universal creatures in the concept of "universal creatures are the same(萬物?一)".

The purpose of this study is to help examine the nature and direction of today's village education community by examining the characteristics of Osan School and Myeongdong School, which were representative national schools during the Japanese colonial period, as village education communities. These two schools were prestigious private schools that became the bases for national and international independence movements at home and abroad. The fact that these schools were able to produce excellent graduates by faithfully carrying out the national education, which was the mission of the time, despite the oppressive situation, was influenced by the village education community formed by the organic cooperative relationship between the school and the village. The two schools have had active support from the village since their establishment, and the schools invited villagers if there was a good educational opportunity or cultural event. The school opened all the facilities of the school to the residents, and the villagers took care of the students and teachers, forming a close fusion between the two sides. Based on this relationship, the school and village made an effort to create an ideal village community based on independence, equality and solidarity. As such, the historical examination of Osan School and Myeongdong School suggests implications that help the village education community move forward to a more mature stage.

If we may practice the nutrition education planned on the basis which carefully grasped the inappropriate behavioral determinants of middle-school students, it might be an effective method achieving the change in perception and behavior improving the distorted perception about the ideal body shape, so we are to suggest the 8 week program of body shape perception improvement for successful nutrition education as follows. The body shape perception improvement program is a step-by-step group consulting program. At the introduction stage, we let them understand the meaning of true beauty and body change of teenage period and forming of sexual identity. At the stage of perception conversion, we let them have the opportunity to observe the status of body perception of the teenager and self-observation. At the stage of correction, we let them criticize the distorted body image in the society with mass media at the same time with the self-reflection. At the stage of maintenance and evaluation, we suggested the behavior guidance while preparing it. Setting this as the basis, we applied the contents such as the evaluations through cultural sharing events making somethings while directly participating. As the target groups to practice education were middle school students, we considered the learning level and behavioral features of the middle school students, and composed the programs including the methods such as role play, watching real things, media production, discussions and experiences. If the program of body shape perception improvement developed at this study could be utilized at the field of schools, the teenagers can change their ways of thought naturally avoiding the view about unified appearance rightly perceiving negative self-image that the teenagers can have and if the group consulting can be practiced regularly at each school, many students may experience the change in perception, so it might solicit the improvement of health of the families and local societies as well as that of the individual student.

This study considers types of expression and examines aesthetic characteristics by analyzing images expressed through space directing at Chanel Fashion Shows. The conclusions of this study are as follows. The expression types on space directing at Chanel Fashion Shows are what is presented by distributing huge objects associated with Fashion Shows at the center or back of the stage, integrating several detailed decorative elements while maintaining the morphological characteristics of the runway in a linear form, and utilizing an inartificial place or newly forming the whole stage. The symbolism characteristic was first indicated for the aesthetic characteristics on space directing at Chanel Fashion Shows. Symbolism is indicated through the identification of an implicit meaning towards a specific object. The symbolism was highlighted utilizing elements or stories that have a deep association with Chanel. Second, the characteristic of ecology was expressed through the recognition of the importance of the ecological environment by escaping the harmful practices of civilization such as environmental disasters and human alienation. The expression of visual ecology was emphasized utilizing themes related to environmental disasters or reviving the space of primitive nature. Third, the characteristic of fantasy was shown to express thoughts that originated from the human yearning for the ideal world contrary to an incomplete society. Fantasy was created by the inaccessible object in reality and a change in spatial structure. Fourth, the characteristics of amusement expressed pleasure, which is the instinctive desire truly immanent in a human being. It was natural amusement, which was advocated as freedom through the integration of neutrality, integrating either diverse elements (which are naturally recognized in our daily life) into Fashion Shows or amusement, which expressed newness through utilizing unusual objects in Fashion Shows.

A numerical design analysis is conducted to search for an optimal shape of outlet in a rotating-disk CVD reactor. The goal is to suppress flow recirculation that has been found in a reactor having a sudden expansion of flow passage outside of the rotating disk. In order to streamline gas flow, the sidewall at which the flow in the Ekman layer is impinged, is tilted. The axisymmetric laminar flow and heat transfer in the reactor are simulated using the incompressible ideal gas model. For the conventional vertical sidewall, the flow recirculation forming in the corner region could be expanded into the interior to distort the upstream flow. The numerical results show that this unfavorable phenomenon inducing back flow could be dramatically suppressed by tilting the sidewall at a certain range of angle. The assessment of deviation in deposition rate based on the characteristic isotherm illustrates that the sidewall tilting may expand the domain of stable plug-like flow regime toward higher pressure. A physical interpretation is attempted to explain the mechanism to suppress flow recirculation.

Microorganisms from the waste water of starch industry, were isolated and a strain, Y-124, possessing a powerful enzymic activity was selected and identified as a member of the genus Bacillus. The ideal cultural condition for the formation of $\alpha$-amylase form Bacillus Y-124 and its preservation was investigated in connection with the biotechnological and industrial approach to the bulk enzyme production. High yield of $\alpha$-amylase was observed in medium containing casein as well as calcium pantothenate in this work. Calcium ions were found to have an effect in forming this particular enzyme. Ammonium phosphate dibasic was an important inorganic nitrogen source for the formation of $\alpha$-amylase. And preservation of this enzyme was greatly affected by calcium or sodium salts. The addition of calcium carbonate or sodium sulfate presented the most effective result for the prevention of its denaturation to various factors. The above data was obtained with crude enzyme preparation.

To achieve the ideal performances of paint film, resins and hardeners have to be chosen and designed in a proper way depending on the exposure circumstance of substrate and the requested physical properties. Six different kinds of clear paints were made in this experiment using alkyd polyol, polyester polyol, polyester modified acrylic polyol and another 3 acrylic polyol resins whose $T_g$ and OH value were partially modified. Then the tests for chemical, physical, and mechanical properties were measured after forming the paint films using aliphatic and aromatic polyisocyanate. The viscosity and elasticity of paint film were then measured in terms of gel point and $tan{\delta}$ using Rheometer and DMA. Through this viscoelastic characteristic test of polyurethane resin, we were able to choose the adequate resins and hardeners which are the most important in the top and primer painting system of urethane paint and, as a result of observing the physical, mechanical, and chemical properties of paint film by urethane, we have finally reached the conclusion that we could apply the proper polyol to top and primer paint for developing the polyurethane paint system.

An ideal orthopedic implant should provide an excellent bone-implant connection, less implant loosening and minimum adverse reactions. Commercial pure titanium (CP-Ti) and Ti alloys have been widely utilized for biomedical applications such as orthopedic and dental implants. However, being bioinert, the integration of such implant in bone was not in good condition to achieve improved osseointegraiton, there have been many efforts to modify the composition and topography of implant surface. These processes are generally classified as physical, chemical, and electrochemical methods. Plasma electrolytic oxidation (PEO) as an electrochemical route has been recently utilized to produce this kind of composite coatings. Mg ion plays a key role in bone metabolism, since it influences osteoblast and osteoclast activity. From previous studies, it has been found that Mg ions improve the bone formation on Ti alloys. PEO is a promising technology to produce porous and firmly adherent inorganic Mg containing $TiO_2$($Mg-TiO_2$ ) coatings on Ti surface, and the amount of Mg introduced into the coatings can be optimized by altering the electrolyte composition. In this study, a series of $Mg-TiO_2$ coatings are produced on Ti-6Al-4V ELI dental implant using PEO, with the substitution degree, respectively, at 0, 5, 10 and 20%. Based on the preliminary analysis of the coating structure, composition and morphology, a bone like apatite formation model is used to evaluate the in vitro biological responses at the bone-implant interface. The enhancement of the bone like apatite forming ability arises from $Mg-TiO_2$ surface, which has formed the reduction of the Mg ions. The promising results successfully demonstrate the immense potential of $Mg-TiO_2$ coatings in dental and biomaterials applications.
