This study discusses the traditional costume of Korea and Japan and cognitive factors affecting its recognition by conducting a survey on both Korean and Japanese students so that comparative analysis of the differences about whether to rent or own traditional costume and about whether the students surveyed have visited the other country reciprocally, can be made to set the future course of the traditional costume which have gradually been worn less frequently and favored by less people. College students of Japan and Korea were chosen for this study and asked to fill in a questionnaire. 491 respondents were analyzed using SPSS10.0 for frequency analysis, factors analysis and t-test. Findings of this study are as follows: Firstly, there were 7 factors affecting the Korean student's recognition of Hanbok while 6 factors involved in Japanese student's recognition of Kimono. Korean students thought highly of the traditional costume and yet had less knowledge of it compared to the Japanese students. Secondly, analysis of the student's recognition of their counterpart's traditional costume showed that there were equally 4 factors affecting the student's recognition. Students found the traditional costume difficult to wear and uncomfortable when worn. Japanese students regarded Hanbok as an abstract form of the traditional Korean culture while Korean students viewed Kimono as a realistic form of something concrete. Thirdly, analysis of the differences about the recognition based on the student's owning or renting the traditional costume. or visiting the counterpart's country, showed that students owning the traditional costume were more positive about the traditional costume and well versed in it. And students having visited their counterpart's country thought more favorably of the traditional costume of their counterpart.

To learn the Earth's shape is a very important achievement standard in the earth science education. The purpose of this study is for helping school experiments by investigating effective experiments of the Earth's shape of each stage of school. Researchers suggest various experiment methods to learn the Earth's shape and investigated appropriate experiments to stage of elementary school, secondary school, high school and university for 26 pre-service teachers. As a result, there is difference between schools in effective experiments of the Earth's shape. Pre-service teachers thought that to observe a sail of ship to come back to a harbour is effective for elementary school students. And they responded that to compare the altitude of the polar star by latitudes is good for the secondary and high school students and to compare difference of sight according to height of the ground is effective for university students. They thought that level of the experiment method, abstract thinking and depth of background knowledge should be considered when teachers choose an effective experiment of the Earth's shape.

Objective : In Western medicine, the cause of obesity include overeating, lack of exercise, genetic factor, endocrinal impediment and psychological factor. Since the society becomes more complexed and the tensions among social members gets intensified, psychological factor getting more important. In Oriental medicine, Seven Emotion(七情, in oriental medical term) as an emotional stressor was thought to be a factor of obesity. Therefore the purpose of this study is to examine the relationship between Seven Emotion and obesity in detail. Methods : overview the stress with the view of Oriental medicine and research the relationship between Seven Emotion as an emotional stressor and obesity. Results : 1. Seven Emotion can be understood as an emotional stress in Western medicine. If Seven Emotion is excessive, its extreme mental stimulation causes physical illness. 2. Having influence upon the function of internal organs, excessive Seven Emotion causes obesity. Since it hinders normal flow of Gangi(肝氣), Seven Emotion disturbs healthy function of Bi-Wi(脾胃) and normal fluctuation of Qi. Consequently, obesity is resulted from the accumulation of fat since normal metabolism of body is disrupted. 3. In Seven Emotion-Anger(怒), Joy(喜), Anxiety(憂), Thought(思), Sorrow(悲), Fear(恐), Surprise(驚)-give rise to Gan-bi-bul-wha(肝脾不和), Sim-hi-yang-huh(心脾兩虛), Bi-qi-huh(碑氣虛), Dam-sup-jeo-po(痰濕沮胞) and Wi-wha-sang-youm(胃火上炎) in type of symptom in obesity and therefore, cause obesity.

This study analyzed the thinking types of pre-service chemical cell chemistry teachers according to grade and tried to find out how the education for pre-service teachers had influenced their thinking types. This study found that the pre-service education had failed to form scientific conceptions. Some pre-service teachers thought that college education couldn't help them understand the knowledge about chemical cell. In addition, they are lacking in scientific conception. Even some of them who thought college education was helpful had wrong conceptions. Most of the pre-service teachers' thoughts could not exceed the level of the high school chemistry textbooks. But, Juniors had more scientific conception than other grades through the group discussions about chemistry textbooks' contents in the course of "Theory of Science Teaching Materials". So, Pre-service education should include the pedagogical knowledge with content knowledge treated in secondary school science textbooks for educational effects.

Excitatory amino acids (EAA) are thought to play an important role in producing cell death associated with ischemic and traumatic spinal cord injury. The present study was carried out to determine if the response characteristics of spinal sensory neurons in segments adjacent to degeneration sites induced by EAA are altered following these morphological changes. Intraspinal injections of quisqualic acid (QA) produced neuronal degeneration and spinal cavitation of gray matter. The severity of lesions was significantly attenuated by pretreatment with a non-NMDA antagonist NBQX. In extracellular single unit recordings, dorsal horn neurons in QA injected animal showed the increased mechanosensitivity, which included a shift to the left in the stimulus-response relationship, an increased background activity and an increase in the duration of after-discharge responses. Neuronal responses, especially the C-fiber response, to suprathreshold electrical stimulation of sciatic nerve also increased in most cases. These results suggest that altered functional states of neurons may be responsible for sensory abnormalities, e.g. allodynia and hyperalgesia, associated with syringomyolia and spinal cord injury.

Spinal osteochondroms are very rare, and are thought to arise through a process of progressive endochondral ossification of aberrant cartilage of a growth plate, as a consequence of congenital defect or trauma. A case of diffuse type osteochondroma involving the posterior elements of L1-L5 that progressed after laminectomy in a 33-year-old man is reported. Usually, the spinal osteochondroma shows clear demarcation between tumor margin and normal spine elements, and can be exised completely. However, there was no clear demarcation between tumor and normal spine element in our case and therefore it was not possible to removal completely.

The structure-property relations of ternary copper chalcogenides, $TlCu_{3-x}S_2$ and $\alpha-BaCu_{2-x}S_2$ are examined. The density of states, band dispersions, and Fermi surfaces of these compounds are investigated to verify the reason of the metal-insulator transitions by extended Huckel tight-binding band calculations. The origin of the metalinsulator transitions of non-stoichiometric $TlCu_{3-x}S_2$ and $\alpha-BaCu_{2-x}S_2$ is thought to be the electronic instability induced by their Fermi surface nesting.

Lactic acid fermentation from sucrose as a carbon source was experimented. E. faecalis RKY1 metabolized sucrose efficiently into lactic acid through homolactic fermentation pathway. The optimal sucrose concentration for lactic acid production was found to be 150 g/l with the yield and productivity of 0.97 g/g and $3.7\;g/l\;{\cdot}\;h$, respectively. Lactic acid produced from sucrose was almost L(+)-lactic acid up to 98% based on total lactic acid produced. Therefore, sucrose was thought to be potential carbon source for L(+)-lactic acid production using E. faecalis RKY1.

In this work, Scalar Passive code in Lattice Boltzmann Method is employed to simulate two-phase flow of low Reynolds number in a micro-channel. The mixing characteristics in a micro-channel is a function of Peclet number. The mixing length increases with the Peclet number. It is found that with the inclusion of static elements at the channel, rapid mixing of two liquids can be achieved, as shown by the results of computer simulations. The enhancement in mixing performance is thought to be caused by the generation of eddies and by lateral velocity component when the mixture flows past static elements. The results indicate that the size of static element has more effect on the mixing than the number of static element.
