Light is an environmental element which is essential for a man to live and do creative activities in residential area. Especially, modern people arc used to live under artificial light interior surroundings for much time. Currently, the average illumination level of the present apartment is improving, but it still does not reach the recommended level because the present apartment's luminous environment is only based on the life behavior which puts its priority to clear vision. Therefore, it is necessary that proper standard illumination must be used for various use and purpose. From this point of view, this paper investigated the essence of light in the residential area and the luminous environment for apartments was measured. This paper finally suggested well-coordinated lighting condition, derived from the measurement and analysis of luminous environment in these cases.

In tactical theater, it is crucial to detect ground moving targets and to locate them precisely. This problem can be resolved by using SAR (Synthetic Aperture Radar) sensors providing GMTI (Ground Moving Target Indication) capability. In general, to implement a robust GMTI sensor is not simple because of the strong competitions between target signals and clutter signals from the ground, and low speed of moving targets. Contrary to the case that a delay canceller is mostly suitable for ground surveillance radars, DPCA (Displaced Phase Centered Antenna) or STAP (Space Time Adaptive Processing) techniques have been widely adapted for GMTI function of modern airborne radars. In this paper, a new scheme of DPCA using two passive antennas with vertical separation is proposed, which also provides good clutter cancellation performance. The proposed scheme realizes full azimuth coverage for DPCA operation on an airborne platform, which is impossible with classical DPCA configuration. Simulations using various conditions have been performed to validate the proposed scheme, and the results are acceptable.

The objective of this research study is to investigate the optimal process parameters of electrical discharge machining (EDM) on SCM440 steel with copper as a tool electrode. The effect of various process parameters on machining performance is investigated in this study. Modern ED machinery is capable of machining geometrically complex or hard material components, that are precise and difficult-to-machine such as heat treated tool steels, composites, super alloys, ceramics, etc. This paper reports the results of an experimental investigation by Taguchi method carried out to study the effects of machining parameters on material surface roughness in electric discharge machining of SCM440 steel. To predict the optimal condition, the experiments are conducted by using Taguchi's L27 orthogonal array. The work material was ED machined with copper electrodes by varying the pulsed current, pulse on-time, voltage, servo speed and spark speed. Investigations indicate that the surface roughness is strongly depend on pulsed current.

필자는 스피노자와 퇴계의 사유체계의 유사성을 넘어 리와 이성의 능동성에 방점을 두어 독창적인 탈주자학적, 그리고 탈근대적 행보를 걸어 온 퇴계와 스피노자의 철학을 논의하고자 한다. 자연과 인간의 조화를 꾀한다는 공통성에서 스피노자와 퇴계를 형식적으로 평형대 위에 양자를 올려 놓는 데에 대해서는 이의를 달 여지가 없다. 필자는 이러한 논의를 바탕으로 하여 스피노자와 퇴계를 능동과 수동의 테제 위에 올려놓고 그 공통성을 추론하고자 한다.

Derived from the juxtapositional model of Comparative Literature, this article analyzes two movies, The Story of Pao (Chuyện của Pao, directed by Ngô Quang Hải) and Into the Wild (directed by Sean Penn), using eco-criticism and focusing on two specific aspects: looking for the relationship between "culture" and "nature" and questioning the ideology that puts people at the center of the natural world. Specifically, the article points out similar tones in discovering and praising the beauty of nature, and at the same time, focuses on explaining the "disagreement" and "harmony" in behaviors of different communities towards Mother Nature in these two films. Finally, The Story of Pao and Into the Wild are both read as discourses that participate in the repositioning of human beings in the natural world. The purpose of juxtaposition, therefore, is to seek a new existential dimension for the works, providing an opportunity to uncover and reveal hidden layers of meaning of each text.

An Old document(Diploma) is a historical and unique record, so it must be collected, arranged, and preserved for research as soon as possible. Especially, for the effective use of the Old Document(Diploma), it is needed to arrange and describe the material systematically on the ground of modern archival theory. The Kyujanggak Archives in the Seoul National University has published 23 volumes of Old document(Diploma) material Old Document(Diploma). But they seem to cause the readers inconvenience, because the materials are classified and gathered only by genre, the titles or the orders of the materials are not standardized, and there is no description about the content of each Old document(Diploma). Jangseo-gak Library in The Academy of Korean Studies has also published the series of Old document(Diploma) material Old Document(Diploma) Collection. However the case is not different, since they are all mixed up with materials classified and gathered by genre, family, academy, or local school. And a great part of the materials have no titles and no description about the content of each Old document(Diploma), either. About the arrangement and description of the records, European and American archival science has established the theory of l)the principle of provenance, 2)the principle of original order, 3)levels of control, 4)collective description. These theories are valuable for the effective use of Old document(Diploma). On the viewpoint of the principle of provenance, Old document(Diploma) materials should not be classified by subject and genre, but by family and person. Then, the Old document(Diploma) materials, after collected by the unit of family or person on the viewpoint of the principle of provenance, should be arranged in their original order for more detailed arrangement and furthermore, for the work to find their relationship. This is so called the principle of original order. The hierarchical management of the Old document(Diploma) materials, for example, classifying by record group, sub-group, series, item and so on, is the concept of the levels of control, and comprehensive description of the each hierarchical structure is the concept of the collective description. Let's apply these archival theories to 34 pieces of the Chung, Man-Seok's material in the series of Old document(Diploma) material Old Document(Diploma). First, collect the Old document(Diploma) materials into Chung, Man-Seok's collection(the principle of provenance), which were scattered in the series classified by genre. Secondly, rearrange them chronologically(the principle of original order), and then we can find the comprehensive information about Chung, Man-Seok. For the hierarchical management of the Old document(Diploma) materials, we should establish a few concepts from the general, large group to specific, small item. The concepts can be organized as following; l)record group(Chung, Man-Seok record group) - 2)sub-group(personnel document, property document, family document, social activity document, political activity document, etc) - 3)series(gyoji-series, gyoseo-series, yuji-series etc. in the personnel document) - 4)folder(document with additions) - 5)item(one document). According to the the theory of the collective description, in the level of record group, there should be a collective description of Chung, Man-Seok's biography or a summary of record group. Similarly, there should be a collective description of a summary of sub-group in the level of sub-group and a summary of series in the level of series.

As Confucian ideology dominated all over the society, the androcentric patriarchical society in the last of Chosun Dynasty produced the unequal power relationship between man and woman. It was traditional hostesses(kisaengs) who uniquely had an occupation among the women in this society. In modern society. they are reinterpreted as 'fashion leaders' or 'professional career women with expert knowledge and it caused a lot of the studies of them to be in a progression vigorously. Therefore this paper studied on the influence of the traditional hostesses(kisaengs) -who were educated and permitted in ther social activity formally in a Confuanism-governed society which forbided a woman to participate in a social activity and which did not gave ladies any formal education. The general hostess in the beginning time of the Chosun Dynasty imitated the hair shape of women in the yangban family which formed the highest class in the Chosun Dyansty and it reflected their aspiration for the highest social class. Howerver, coming into the last age of the chosun dynasty, a reverse phenomenon -that women in the yangban family imitated the general hostesses' hairstyle -occured due to the spread of a genre painting ＆ the concubine system. The general hostesses were educated systematically and did social activity and influenced hair shapes as they were independent economically and their influence in the part of hairstyle appeared as great and high EONJIN MEURI and as one-sided EONJIN MEURI. Regarding-as the result of this study on the influence of the traditional hostess's hair shapes on the ladies hair shapes in the last of Chosun Dynasty -that the traditional hostesse of the last age of chosun dynasty played a role as a fashion leader of the ladies at the same age. the general hostesses in Chosun Dynasty should be revaluated... And the study of ladies which were hidden behind the scenes of Confuanism should be made much more.

In today's society, being considered ecological in fashion design and having a cultural and humanistic approach is important. Using a technological approach, the fold concept was applied to understand and analyze the ecological characteristics of a modern fashion aesthetic design. The concept of 'Ecological Aesthetic Design', which we discuss in this study, is part of human nature, and the design concept is used to consider the relationship between the man and the environment to the design of Victor Papanek. From the perspective of interrelation between the components of an ecosystem, the possibility of the fold's application to ecological aesthetic design can be summarized by wholeness, biodiversity, evolution, homeostasis, and circularity. The concept of the fold is revealed mainly through three types of characteristics: indeterminate complexity, potential continuity, and decentralized interaction relationship. Based on the characteristics of the concept presented earlier, this study conducted a case review by distinguishing contemporary fashion that applied the complex, various, and indeterminate fold concepts into flexible transformation, continuity, and complementary circularity. This study was interpreted from the ecological aesthetic point of view based on the nature of the contingent folds presented before applying modern fashion concepts. It focused on the morphological side, and excluded the material aspects of the case study in order to examine the complex, diverse and content aspects. The result of the study is as follows. The study of the research areas that help the understanding of the changing fashion phenomenonneeds to be encouraged, and there should be a new research category, which can contribute to the ecological aesthetic design concept conversion.

This study surveys children's costumes and games from the 11 Genre paintings by Junkeun Kim in the book "Korean Games(Stewart Culin 1858-1929)". The character of the general dress-costumes, games and the culture of life from the late $19^{th}$ century in genre painting of Junkeun Kim are as follows. The study results on the games are as follow. The boy's games are kite-flying, spinning tops, playing shuttlecock with the feet, blindman's buff, yut("Four-Stick Game"). Girl's games are seesaw with board, blindman's buff, marbles. Combined games are mount shoulder, sledge, tightrope walking for men with boy. The strengthen one's body type were seesaw with board, tightrope walking, the compete score type were playing shuttlecock with the feet, marbles and the multi complex type were yut("Four-Stick Game"), kite-flying. Through genre painting in the $19^{th}$ century we know a boy's 'Jeogori 'and 'Ba-ji' were similar to a modern man's and boy's 'Hanbok' with a traditional method of wearing. We believe that the originality of a traditional costume was an unchangeable characteristic. Girl's 'Jeogori' and 'Chi-ma' changed in length and width, and method of wearing; however, the basic shape did not change. The analysis for artist's genre painting which was ordered by a foreigner and the late of $19^{th}$ century's children's costume and game of life culture is useful to match the counters and show how to wear a modern Korean costume used to understand the 'Hanbok' and establish a costume of life.
