The purpose of this study is to investigate the effects of job satisfaction and life satisfaction on teacher-children interactions in kindergarten teachers. The tests of Job satisfaction scale, Life Satisfaction scale, Teacher-Children Interactions scale were administered to 320 public and private kindergarten teachers located in Gyeonggi-do, Gangwon-do. The statistical method employed for data analysis was Pearson's correlation analysis and multiple regression analysis. The results of study were as follows. First, the higher factors of job satisfaction (the teaching consciousness, development, innovation, autonomy, fellowship, and reward), the higher the teacher-children interaction. The higher the workload, the lower the verbal interaction between teacher-children. Second, the higher the life satisfaction of kindergarten teachers, the higher the emotional, verbal, and behavioral interaction between teachers and children. Third, the relative influences of the predictors on the overall interaction between teacher and children are life satisfaction (β=.24), development (β=.22), and fellowship (β=.16) and the explained variance are 25%.

In this paper, we propose two algorithm for improving the performance of wireless localization(Trilateration and Least Square) based on the range based approach method in indoor environment using RSSI for ranging distance. we propose a method to discriminate the case that has relatively large estimation errors in trilateration using Heron''s formula for the volume of a tetrahedron. And we propose the algorithm to process the discriminated types of distance using the absolute value calculated by Heron''s formula. In addition, we propose another algorithm for the case of which the number of anchor nodes larger than three. In this case, Residual Weighting Factor(RWGH) improves the performance of Least Square. However, RWGH requires many number of calculations. In this paper, we propose Iterative Weighted Centroid Algorithm(IWCA) that has better performance and less calculation than RWGH. We show the improvement of performance for two algorithms and the combination of these algorithm by using simulation results.

This study was conducted by implementing a structural analysis regarding adult learners' learning outcomes and their affecting factors in the lifelong educational institutions in Daejeon area with 960 adult learners. Research result was as following. First, learner and educational characteristics were confirmed to have an indirect impact on learning outcomes, which were mediated by learning satisfaction and commitment. Second, adult learner's characteristics directly influenced to learning commitment and satisfaction as well as educational institutions did. Third, learning commitment also directly affected learning satisfaction and outcomes. Fourth, learning satisfaction had a strong influence on learning outcomes. By all accounts, learning outcomes was directly influenced by learner, educational characteristics, and learning satisfaction. In addition, learning outcomes was indirectly impacted by mediating with learning satisfaction and commitment. Therefore, lifelong educational institutions should reinforce any strategies in order to enhance learning outcomes such as developing and providing more variable programs, making better class atmosphere and facility, positioning highly qualified teachers, and one-stop administration services.

The Korean clothing culture has shown rapid changes along with influences of western cultures, with social changes due to the liberation from Japan, the Korean War, and the economic growth concentrated on export since the westernization of Korea had begun. Also clothing materials, as a phase of such culture, have been changed. Among silk fabrics, "Dan (단: damask of satin texture with Korean traditional patterns are inwoven)", which has been concerned one of the most beautiful and precious fabrics due to its complexity and difficulty of processing. Since the beginning of the Era of Enlightenment(Kae-hwa-gi), Dan fabric materials and weaving methods have changed. It seems that the figured texture using the Jacquard loom began in 1936. when the Jacquard machine began to be imported from Japan into Korea. From that time on, new fabric materials, such as yangdan (양단), and popdan (법단), hobakdan (호박단), silk and rayon mixed Dan(교직양단) began to be produced. Before 1950's there were some restrictions about the Number of wefts, so the production of the one colored dan(단색단) was more common than that of the multi colored dan(다색단). But with the spread of 4$\times$4 shuttle box loom (양사정직기), various kinds of the multi colored dan have been produced after 1960's. Around the end of 1980's, automatic shuttle change loom have been generalized and 7 color dan(칠색단), 9 color gumsadan (구색금사단) have been current in multi colored dan. In terms of materials, synthetic and chemical textiles had been used widely and alter 1980's most fabrics, of which the ground weave is not being woven with satin-weave but being woven with plain or twill-weave, are named Dan in general.

This study examined what meaning East Asian women showed in their costume history through a discourse of hair adornments such as wigs and that Gache was not just a luxury decoration. In addition, we examined Gache hair trends with Eonjeun-meori (braid wraps around the entire head) in the Joseon dynasty (Korea), Gigye(旗?) hair in the Quing dynasty (China) and Mage(?) hair in the Edo period (Japan) during the $18^{th}$ and $19^{th}$ centuries. The significance of the phenomenon of East Asian Gache culture in the $18^{th}$ and $19^{th}$ centuries was analyzed from the internal desires of women. The details are as follows. First, the magnification by the hair decoration was identified with self-authority and used as a sign to express self-respect or a desire for self-esteem. The extended Gache was an external body extension to raise self-authority and increase activeness. Second, self-satisfaction through showing off was associated with a women's search for identity. There was excessive consumption to boast status, wealth and femininity, but the mania continued because women obtained psychological satisfaction by feeling that their sacrifices for the Confucian order were compensated. Third, the frenzy of Gache was accepted as a way for women to resist social regulations and find themselves as main participants in social activities. Showing their appearance in East Asian Gache culture was a way of inner self-searching and a process for women to find themselves as a social entity.

This is a qualitative study of pre-service teachers' experiences in a teaching practicum course which attempted to identify the characteristics of the course that has been recently revised as professional education course. Data were collected from college students who took the professional education courses including the teaching practicum course by using both a survey on the opinions and suggestions of the students on the teaching practicum and a in-depth interview with 12 students of them. The results are as follows. First, pre-service teachers' perception of a teaching practicum course was divided into two sides : functional side and sociocultural side. The formal is that the professional education courses significantly handed to discipline practical jobs related to educational administration. The latter is that the professional education courses significantly handed to deal for teachers like pay step, extra pay, vacation, and leave of absence. Second, the pre-service teachers had suggestions that were divided into the 'curriculum content' and the 'instructional method'. For instance, regarding the 'curriculum content' they suggested such things needed as 'lessening and differentiation of content, sensitive about the scene, and lesson hands-on', and as for the 'instructional method' they suggested such things needed as actively 'doing, participating, assessing, coursework participating'. Based on these results, I have comprehended the pre-service teachers' positive response. Untill now, we have perceived that the professional education courses is excessively theory-oriented one. But a teaching practicum course is different. Meanwhile, It is not identify what the teaching practicum course as teaching refinement education course is. Due to this cause, I have comprehended that 'curriculum content' and the 'instructional method' is plunged in confusion. As pointed out this, I did concrete proposals in response to such a confusion. This proposals have helped decided on a direction of a teaching practicum course.
