The objective of this study is to reduce the gloss of thick denier PET yarn. Pure PET yarn exhibits considerable shine. Since wig fiber is thicker than clothing fiber, it is not easy to reduce the gloss. In this study, three types of inorganic particles, namely, $TiO_2$, $SiO_2$, and talc were added to the PET yarn to test the tendency of gloss reduction. Moreover, the gloss variation was tested according to the cross section of the fiber, the spinning temperature, and the draw ratio. Owing to the addition of the particles, the crystallization of PET was promoted and the crystallization of talc was exceedingly rapid. The manufactured yarn with the added $TiO_2$ was the least glossy. The gloss of the fiber decreased in the following order: star shape > circular shape > peanut shape. The spinning temperature had no effect on the gloss, however, the gloss of the fiber increased as the draw ratio increased.

The electrospun nano-web is a very good candidate to replace Gore-Tex due to its similar structural characteristics. However, its water resistance is relatively low compared to Gore-Tex. In this study, silicone oils were applied to enhance the water resistance of nano-webs by coating their surface using the cross-linking reaction of the oils. Treating conditions such as time, temperature, and concentration of oil were varied and moisture permeability and water resistance were examined. DSC was used to test the curing reaction of the oils. FT-IR and scanning electron microscopy were used to confirm the crosslinking reaction between oils. The best result was obtained by treatment with an oil concentration of 3%, under the thermal treatment conditions of $150^{\circ}C$. for 120 s. As a result, the durability and water resistance of the fabric were improved, while moisture permeability was partly maintained.

Human behavior is a complex result of our intentions, our perception of the immediate situation, and our assumptions or beliefs about the situation and the people in it. In order to understand how organizations function, it is necessary first to understand how the people in those organizations function, especially the managers who make organizational decisions function. On that ground, it is important for managers to make decisions of the kinds of assumptins of human nature. The purpose of this study was to examine the school administrator's desirable view of human nature in school organizations. Firstly, the school administrator's view of human nature divided into three basic views and were surveyed as follows : ①traditional model ②human relations model ③human resources model. Secondly, each effectiveness from the viewpoint of the organizational health was discussed. Some of them could be summarized as follows : ① The school administrator's view of human nature had different characteristics in line with three eras like the scientific management era, the human relations era and the era of administrative theory. ②The school administrator's assumption about human nature changed the characteristics from the viewpoint of rational-economic assumption to that of humanistic view. ③The more the organization develops into humanizing, the more it takes on the disposition of open system. ④The view of human nature of the human resources model should be considered more desirable to the school administrator than the view of human nature of the traditional model and human relations model.

It is believed that student teaching is the most significant aspect of teacher education. Despite knowledge of research on teaching, learning, and educational psychology, many critics have charged that student teaching has not developed a sound theoritical basis, and has no uniform or standard structure. In addition to this, student teaching is influenced by social and educational changes. Hence student teaching has to be inquiry on and on. The employed methods were analysis of reference books and statistical treatment of questionnaires. Findings from these data were discussed in regard to the student teaching periods, the local co-operating schools as practicing schools, the number of student teachers per class, the qualifications of co-operating teachers, the improving measures for student teaching administration in the attached elementary school and co-operating schools, the welfare of student teachers, the criterion of the importance of student teaching contents, and the improving measures for teachers college curriculum and student teaching programs.

No brief or Simple Statement will suffice for defining the task of educational administration. The factors which define the task of educational administration constitute no fixed body of dogma. Instead they may be viewed as variables influenced by numerous factors of a psychological as well as a social-cultural and individual nature. The task if educational administration is indeed complex. The purpose of this study is to examine the historical development of the task of educational administration and to analyse categories of administrative tasks in the U.S.A. and korea. ① Those in the U.S.A. The Stages of development of the principalship are as follows: First stage was a single teacxher in a one-room school; Second stage, principal teacher stage; Third stage, teaching principal stage; Fourth stagem supervising principal stage. In the field of educational adminitration, the 1950s and early 1960s witnessed debate the number and nature of these tasks. The debate was taxonomic, not theoretical. In the 1970s in order to perform effectively in the principalship, the functions of principalship were paid keen attention. It focused on the tasks that occupied the bulk of the principal's time and analyzed them according to the major competencies that were demonstrated by an effective school principal. In analyzing categories of administrative tasks, there were some different aspects according to the researcher and phase of the times. ②. Those in lorea The typical school in our early history was the one-room, one teacher school like Sodong as the institution of private education. Now principalship is professionalized. The tasks of educational administration in Korea can be said to have been influenced by them mainly of the U.S.A. Therefore theories of administrative tasks had a little bit different aspects between two countries.
