In this work, nano-needle structures ate formed to solve problem, related to low density of quantum dots for nano floating gate memory. Such structures ate fabricated and electrical properties' of MIS devices fabricated on the nano-structures are studied. Nano floating gate memory based on quantum dot technologies Is a promising candidate for future non-volatile memory devices. Nano-structure is fabricated by reactive ion etching using $SF_6$ and $O_2$ gases in parallel RF plasma reactor. Surface morphology was investigated after etching using scanning electron microscopy Uniform and packed deep nano-needle structure is established under optimized condition. Photoluminescence and capacitance-voltage characteristics were measured in $Al/SiO_2/Si$ with nano-needle structure of silicon. we have demonstrated that the nano-needle structure can be applicable to non-volatile memory device with increased charge storage capacity over planar structures.

In general, collections in museum are kept in storage according to a preservation and administration program in long or short term, after conservators’ conservation treatment. Museum activities related to conservation science are common to do before and after exhibitions. That is, the museum collections include a flow mechanism, which circulate a space in where conservation science related activity is carried on centering around its storage. The purpose of this study is to suggest the design guidelines of a conservation area in a museum. The results of this study as follows. First, to program space planning, conservation area of museum is divided into 4 kinds of zone. Second, space for relics unloading in basically includes ‘unloading room’, ‘control room’, ‘worker room’, ‘unpacking room’, and ‘unloading tools storage’ and considers to install ‘outdoor arrangement space’, etc. In case of space for making relics collections, ‘arrangement room’ and ‘temporary storage’ are separately planned in order to arrange and temporarily store relics taken in. Conservation analysis space should be divided into 2 kinds of zone, ‘conservation analysis lab’ for analysis of collection characters and ‘restoration lab’ for conservation treatment in the bigger museum. In case of large-scale museum, conservation treatment space is basically classified with characters of museum collections. And it considers installing ‘waterlogged wood lab’, ‘painting’ clothes treatment lab’, ‘storage of treated relics’ etc. Third, for ‘the spaces for analysis treatment’, must consider activity contents and sizes of the department for scientific conservation every museum, can classify in detail required space, and must review the space for relics settlement in construction.

To complete the appropriate pattern language as a planning tool for suburban houses in Korea, this study reviews the characteristics in applying the pattern language to suburban houses in Korea by creating the pattern application examination chart regarding 110 patterns in architecture and evaluating and analyzing 24 examples in terms of the applicability of the patterns, the results of which are as set forth below. Firstly, when grouping the upper 31 patterns by similar characteristics, it was distinguished by the characteristics relating to (i) securing of lighting and viewing; (ii) placing of buildings and space and adjustment of inside and outside privacy through such placing; (iii) placing of proper motion line and functions of adjacent space according to such motion line; and (iv) determining of important space such as personal room, area for couple or children, staircase, entrance, hallway, etc. Secondly, when analyzing the reasons that the lower 41 patterns have not been applied, it was characterized by (i) the work space not suitable for suburban houses or the patterns suitable for commercial space; (ii) the patterns not suitable in Korea due to cultural differences; and (iii) the patterns whose applicability cannot be confirmed due to the limitation of examples and materials used in this study. Thirdly, the analysis of each pattern group (A through M) revealed that the pattern groups D and G are rarely related to suburban houses and J and M are patterns whose applicability cannot be determined in this study. Another characteristics is that the pattern groups B, E, F, I and L which obtain high scores in applicability are importantly reflected in planning for suburban houses in Korea. Fourthly, this study renders the average score of applicability, and the applicability rate, of the examples and confirms the number of the patterns applied in confirmity, patterns partially or potentially applied and patterns not applied at all.

현대건축에서 보여지는 표피와 내부공간의 관계성에 관한 연구 -헤르조그와 디 뫼론 작품을 중심으로-

정성욱 ( Sung Wook Jung ) 한국기초조형학회 2010 기초조형학연구 Vol.11 No.6

현대 건축가들은 내부와 외부의 관습적인 관계를 벗어나기 위해 부단히 경계로서의 표피에 대해 탐구하고 있다 이전의 표피가 실내공간을 외부공간으로부터 보호하는 기능과 공간 표면의 장식적 기능을 동시에 수행했다면 최근에 일어나고 있는 표피의 변화는 이러한 기능들을 실내공간으로 전이시키면서 실내공간을 강조하여 또 하나의 시각적 스킨으로 등장 시키는 경향을 보이고 있다. 이에 본 논문은 건축 표면에 나타나는 현상에 치중하고 구축적 표현을 통해 외부와 내부를 관계 맺는 건축언어의 새로운 영역을 개척하는 헤르조그와 드 뫼론의 작품들을 표피와 내부공간의 관계적 측면으로 분석하였다. 표피에 대한 이론적 고찰을 통해 표피의 개념과 근대 이후 건축과 현대건축에서 보여지는 표피의 특징을 이론적으로 살펴본 후 헤르조그와 드 뫼론의 건축물들을 대상으로 표피에서 보여지는 특징이 유사한 성격의 작품으로 분류하였다. 분류작업을 통해 정리된 표피에서의 투명성, 패턴화, 재료의 혼성이라는 공통점을 가진 건축물들의 표피와 내부공간의 관계성을 살펴보았다. 분석결과 A. 표피의 투명성과 내부공간의 관계성은 1)인식적 경계의 연장 2)주변환경 내부로 동화 3)내부공간 확장 4)차양의 가변성을 이용한 선택적 조망 B. 표피의 패턴화와 내부공간의 관계성은 1)인식적 경계의 형성 2)외부 풍경의 파편화 3)거리에 따른 이이지 변화 C. 표피재료의 혼성과 내부공간의 관계성은 1) 인식적 경계의 소멸 2)재료의 특징에 따라 외부 요소의 선택적 유입 3)외부 풍경의 변형 4)내부공간의 물성강조로 각각의 공통점을 정리할 수 있었다. 표피와 내부공간에 대한 논의를 몇 가지 관점으로 요악하여 살핀다는 것은 무리일 수 있으나 표피 자체의 특징만이 아닌 표피에서 파생되는 내부공간을 중심으로 살펴보았다는 점에서 의의가 있다 하겠다. Modern architects are researching for skin as a border to get out of internal and external conventional relationships. Wile the former skin carried out the protective and special ornamental function at the same time, now the change of the skin tends to transfer these functions to the inside spaces and make another visual skin by emphasizing them. This paper analyzed the works of Herzog and de Meuron which opened up a new world of architectural languages giving the relationships of the internal and external in terms of relationships of surfaces and inside spaces. The study of skin has classified the architectures of Herzog and de Meuron as similar works after looking through the concept and characteristics of skin in modern and after modern architectures and then examined the relations between inside spaces and the surfaces of buildings which have something in common with the transparency of skin, pattern, and mixing of materials. As a result, A. the relationships of transparency of skin and inside space are 1)extended cognitive boundary 2)assimilation towards inside surroundings 3)inside space extension 4)selectional view using movable shading B. the connections of skin pattern and inside space are 1)cognitive boundary formation 2)outsides into fragment 3)image transformation with distance C. the connections of mixing of materials and inside space are 1)cognitive boundary extinction 2)selectional exterior influx according to the materials 3)exterior transformation 4)emphasizing inside space.

In recent years, service delivery systems employing a self-service approach have been rapidly spreading. Since a self-service system provides a lower product price, it attracts more customers. However, some system managers are still hesitant to accept a self-service system, because there is no systematic model to predict its performance. Therefore, this research attempts to provide a systematic and quantitative model to predict the performance of a self-service system, focused specifically on a self-service gas station. Under this model, the traditional queuing theory was adopted to describe the general self-service process, but it is also assumed that some changes occur in both the customer arrival rate and the service performance rate. In particular, the price elasticity was introduced to capture the change in the customer arrival rate, and the existence of learning effect and helpers were assumed to design the changed service performance rate. Under these assumptions, a simulation model for a self-service gas station is established, and three performance measurements, such as average number of customers, average waiting time, and Utilization are observed, depending on the changes in price difference and helper-operating time. In this research, the optimal operation strategy for price differentiation and helper-operating time is proposed in accordance with the level of the customer learning rate. Although this research confines the scope of the study to the self-service gas station model, the results of this research can be applied to any type of self-service system.
