The purpose of this study is to analyze spatial configuration of the unit floor plan characteristics of the apartments built in Seoul Metropolitan area by using the Space Syntax methodology and finally to test the relationship between space in the unit floor plans. So the unit floor plans are analyzed using sector graphs from justified graph and computer programs based on the Space Syntax model and compared by size. The results are as follows; The sector graphs are summarized in 14 types. The total depth of spaces is not in proportion to the plan area. And the global and local integration and intelligibility are inversely proportional to the area. But in the case of largest areas(265$m^2$ and above), the integration and intelligibility increase.

The symmetry is general geometric design principal in contemporary architecture shape. But, Symmetry sometimes easily causes unreasonable design. In some reason, two of symmetric units in the apartment, one side of unit have very reasonable plan and arrangement but opposite side unit nay not. For example, if the kitchen on right unit had right-handed arrangement, the symmetrical other would have left-handed kitchen arrangement. In addition to this, if each house unit has the same plan but different direction, each unit has different usage or affects the residents' life pattern. Nevertheless, Architects use only one unit plan to design public housing development by using symmetric operator (mirror, proper rotation, inversion center) at their option. This study suggests that using group theory and mathematical matrix rather than designer's discretion can solve this symmetry problem clearly. And, this study analysis the merits and demerits between each symmetrical pair of unit plan shapes by using mathematical point group theory and matrix.

The purpose of this study was identifying the user needs for the planning of public space in apartment dwelling units. 298 apartment residents in Haeundae, Pusan responded to the structural questionnaire, which included the residents' satisfaction for the location and size of the living room, the kitchen and the dining room, the space usage of the living room and the dining room, and preferred layout of the public space. The main findings are as follows. 1) The important household characteristics to consider are identified as family life cycle and the number of family members. 2) The levels of residents' satisfaction were differed by the household characteristics and the types of apartment. 3) Activities related to recreation, entertainment, and family meals in living room and formal and informal entertainments in the dining room were occurred in different way as to the household characteristics and the types of apartment. 4) The younger families in the smaller sized apartments had more diverse preference to the layout of the public space.

This study is focused on Resider's Preference of Residential Space to improve Residence Unit Plan. Three Rental Housing Complexes in Jeju which supplied by Korea National Housing Corporation(KNHC) were selected for more detailed Resider's Preference research, which were constructed within 5years. Questionnaire of Total 360 sheets were distributed for each Rental Housing Complexes and total 299 sheets were returned. The results of research are as the followings. Generally satisfaction of environment and living area of home is not high. And also it seem that many residers want to live in housing of average 25.87 pyeong in housing scale. In view and direction of housing Especially, many residers tend to select housing that view is better than direction. With based on like this results, it is proposed housing plan's develop and political supports reflected Jeju's culture condition, life style, climate and so on.

From 1960 year, in Korea, for solving the cityward drifting of problem, A lot of apartment housings were intentionally constructed in the process of industrialization. After 30 years, for solving the stock problem of the deteriorated apartment housing, it has mostly been reconstructed, till now. In this paper, because we try to improve upon the method of the problem which is used n reconstruction, we propose $\ulcorner$Re-using system$\lrcorner$ of a deteriorated apartment housing. This includes all improving spheres of deterioration of faculty and sociality, which are all factors of discomfort and improving method after residents'living, individually and collectively. Accordingly, the object of this paper consequently propose the application of the methods of $\ulcorner$Re-modeling system$\lrcorner$ to all stocks of deteriorated apartment housings.

본 논문은 CMOS의 latch-up 특성을 개선하기 위한 효과적인 mask 설계 방법에 관한 것이다. Mask의 평면구조와 latch-up 파라메타와의 상관관계를 실물 제작에 의한 실험과 컴퓨터 시뮬레이션에 의해 도출하였으며, guard ring의 효과에 대해서도 비교 분석하였다. 실험 결과, 수평구조 바이폴라 트랜지스터의 전류증폭률($\beta$n)이 디자인룰에 반비례하였으며, 수직구조 바이폴라 트랜지스터의 전류증폭률($\beta$n)은 디지인룰과 무관하였다. 스위칭전압과 유지전류는 디자인룰에 비례하였다. Guard ring은 latch-up의 가능성을 줄이는 데 상당한 효과가 있었음이 확인되었으며, Guard ring이 없는 경우에 비하여 전류증폭률의 곱($\beta$n$\beta$n)이 약 31% 감소, 유지전류는 약 25%가 향상됨을 확인하였다.

The aim of this study is to understand the composition of plan and the changing aspect of Louis I. Kahn's residential architecture, Louis I. Kahn's spacial composition is characterized by traditional motives and Ecole des Beaux Art which had influenced him. His constituent factors in geometrical form are classified into the propositional system, the cellular multiplication of a special unit, the Poche Space and others. According to the results of this study obtained from above mentioned subjects, it can be concluded that geometrical factors, which constitute space of plan, are totally expressed as a system of order which unites particular ones into whole one.

The focus of this study was on spatial and interior characterization of recently developed and marketed apartments. The house showrooms in the Seoul Metropolitan Areas that have recently been open were selected and analyzed. The floor plans and relevant materials via website for each showroom provided by major housing development companies were examined, and site visits were made. The finding of this study indicated that high-tech systems were applied to heighten security and safety. It was revealed that various exterior design features were adopted and emphasized, so they affected spatial composition and utilization. Another finding was the use of environmentally friendly materials and features as indoor air quality became an emerging concern. Additionally, it was noticed that features in relation to open housing and interior finishes became more customized to meet different needs of consumers. Therefore, the characteristics of recent house showrooms were summarized into high-tech, environmental friendliness, and customization.

DC Hollow cathode 방전은 약 100여 년 전, Paschen에 의해 실험된 이후로 광원, 스퍼터링 공정, 이온빔 소스 등 다양한 분야에 이용되어 왔다. 최근 태양전지용 마이크로 결정질 실리콘 증착 시, RF CCP의 전극에 복수의 홀 혹은 트렌치 구조를 두어 Hollow cathode 방전 효과를 이용하여 향상된 공정 속도로 공정을 진행한다. 그러나 RF-MHCD (Multi hole cathode discharge) 공정을 위한 최적 규격의 홀 기에 관한 연구는 그 중요성과 응용성에도 불구하고 깊게 이루어지지 못한 바 있다. 그러므로 저자는 Capacitively Coupled Plasma (전극 간격 : 4cm, 전극 직경 : 14cm) 장비에서 평면 전극과 10mm 깊이와 각각 3.5mm, 5mm, 7mm, 10mm 직경의 홀이 있는 4개의 전극을 이용하여 Argon RF-MHCD 방전을 관찰하여 조건 별 최적의 홀 전극 디자인을 도출하였다. 실험 조건은 64.5mTorr ~ 645mTorr압력 범위/ 1A~9A이며, 플라즈마는 전극 사이 중앙에 설치한 RF-compensated Langmuir Probe와, 전극과 전기적으로 접촉하는 1000:1 Probe 와 Voltage-Current Probe를 이용하여 측정되었다. 실험 결과 압력 조건 별로, 최적의 전자 밀도를 유도하는 전극 상 홀의 직경이 달라짐을 확인하였다.
