We investigate the chemical differentiation in F, G, K type stars with and without planets to extend the work by Kang et al. (2011) to various spectral types. Since the primordial chemical composition has been preserved in the stellar atmosphere, stellar metallicity can provide the information on the primordial material, which is the potential building block of planets. Therefore, we can explore the favored conditions for planet formation through the comparison of chemical compositions between planet-host stars (PHSs) and stars without planets. In this work, we analyze 19 F, G, and K type stars. In each spectrum, we measure equivalent widths (EWs) of Fe, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Co, and Ni using TAME (Tools for Automatic Measurement of Equivalent width). The abundances of these species can be derived with the measured EWs and MOOG code (Sneden 1973). Like results by precedent studies, we find that planet-host stars have abundances higher than stars without planets. The typical difference in the abundances of Na, Mn, Co and Ni is $0.4{\pm}0.2dex$. In addition, as found in Kang et al. (2011), Mn is the most different element between PHSs and comparison stars.

The purpose of this study was to provide basic data for better design of Pharmacy after introducing the new system of separation of dispensing from prescribing medicine. To analyze characteristics of interior design in pharmacy and to measure worker satisfaction, a survey was conducted with 255 workers who serve at any Pharmacies located in Busan, Korea. For data analysis, descriptive statistics, t-test, One-way ANOV A were performed with the SPSS Win program(Ver. 10.0). The major findings were as follows: 1) As a result of analyzing the role and functions of the pharmacist is to be classified into many items such as entrance, a waiting room, a dispensary, a medication & consultation area, a drug storage and a worker's room. 2) Natural substances should be used more widely instead of using chemical substances for the pharmacy interior design as finishing materials 3) Pharmacy worker's satisfaction with dispensary is specially low among the total satisfaction which is :slightly higher than the average. 4) The degree of satisfaction between pharmacy workers from different groups varied depending on work hours, and especially long time(over 10hrs) workers showed dissatisfaction. Pharmacy managers need to consider the option of expanding convenience facilities. 5) According to the satisfaction analysis for each pharmacy conditions, the group who worked in 30-pyeong spaces were most satisfied. Since the 30-pyeong space is most standardized space research should be conducted.

The need for adopting automation technologies to improve inefficiencies in interior finishing modeling work is increasing during the Building Information Modeling (BIM) design stage. As a result, the use of visual programming languages (VPL) for practical applications is growing. However, undefined or incorrect space designations in BIM models can hinder the development of automated finishing modeling processes, resulting in erroneous corrections and rework. To address this challenge, this study first developed a rule-based automated interior finishing detailing module for floors, walls, and ceilings. In addition, an automated space integrity checking module with 86.69% ACC using the Multi-Layer Perceptron (MLP) model was developed. These modules were integrated into a design automation module for interior finishing, which was then verified for practical utility. The results showed that the automation module reduced the time required for modeling and integrity checking by 97.6% compared to manual work, confirming its utility in assisting BIM model development for interior finishing works.

The purpose of this study was to devise guidelines for the kitchen workspace of the aged by examining current usage. To achieve this objective, surveys were conducted and measurement were taken between June 15 and lune 30, 2005. The data were gathered from 50 women over 65- years-old who live in the downtown and suburbs of Seoul, Korea. The collected data were processed using SPSS 12.0 for Microsoft Windows and resulted in the following conclusions: The kitchen for the aged needs to be laid out in ㄱ-shape and the refrigerator needs to be positioned prominently. The height of the work counter is relative to the user's height (${\times}0.49{\sim}056$). and the length varies depending on the available space of the house and the type of work counter needed: however it was found that it should be at least 270cm Concerning the depth of the work counter, the standard sizes (60cm) currently on the market did not cause any inconvenience. It was found that the sink must be designed to allow for some space at the bottom so as to ensure comfortable sedentary work. Also, an electrical oven was preferred over a gas-fuelled one. Finally, the height of the upper cabinet should be relative to the user's height at ${\times}0.85{\sim}1.0$ from the floor to the bottom of the cabinet.

도시산업구조의 진단과 예측은 지속가능한 도시발전계획수립을 위한 주요한 과제이다. 지금까지의 산업관련 도시공간구조 연구들은 주로 도시산업체 자료나 총 종사자수 자료를 활용하여 산업유형별 공간분포의 측정에 집중되어져 왔다. 그러나 최근 비정규직 문제를 포함한 근로자의 종사상 지위가 중요한 이슈가 되는 시점에서 본 연구는 읍면동 단위의 1994년 및 2004년 종사상 지위별 자료를 수집하고 동 변화자료를 기반으로 공간분석 단위를 일치시킨 후 GIS를 활용하여 종사상 지위분류체계 자료를 활용한 도시산업구조의 질적 변화를 공간적 관점에서 해석하였다. GIS환경에서 부산시 산업구조의 종사상지위 유형별 분석 결과는 다음과 같다. 첫째, 전통적인 노동집약적 산업이 한계에 부딪히고, 서비스업 및 도소매업은 영세한 생계형으로 진행되어 부산의 고용흡수력이 떨어질 수밖에 없었으며 통계상으로는 종사자의 수가 증가하였으나 비정규직과 비임금 노동자가 급증하면서 부산지역 일자리의 질이 하락하고 있는 것으로 측정되었다. 둘째, 전통적인 도심지는 쇠퇴하는 반면 신도시나 신흥공업단지가 형성된 지역, 제조업보다 서비스업이 발달한 지역이 일자리가 증가하는 경향을 보였다. 본 연구의 결과는 도시발전의 근간이 되는 산업구조의 행태적 패턴 뿐 아니라 종사상지위라는 질적 평가를 통한 장기적 차원의 산업발전계획안 마련을 위한 기초자료로서의 활용을 기대한다.

What is an exhibition? Is it of the system which is designed to serve Art Works in their representation, or is it a place where the artistic presentation could be considered as art work itself? After modernist era, the role of exhibitional space might have been shifted from those two principle raison d'$\^{e}$tre of exhibitional space into another, a new one. What Deleuze would call it as he borrowed the term from Spinozian philosophy : the Affectional Space. This new type of exhibitional space has been announced since 1969 when a Harald Szeeman, young independent curator and art critic from Swiss, has organized his brilliant exhibition "When Attitudes become Form" in Bern. For sure, these intensities in curatorial practices have been existing before like some early 20th century exhibitional efforts by Marcel Duchamp, El Lissitzky, Yve Klein, etc. It has influenced much on many of, otherwise most of contemporary art exhibiting practices. And now it seems to be necessary to give it a conceptual idea which could enlighten better the new paradigm of exhibitional practices that we try to clarify. I would propose the idea of that new exhibitional space as "space of non-organic becoming". This idea is inspired by Deleuze's ever famous philosophical work Thousand Plateaus, which, with Folds by the same author, has contributed to many contemporary and aesthetical debating issues. What is "affect"? Explaining about Spinoza's principle concepts, Deleuze defines it as a kind of durations or variations which are constituted by different levels of perfection. One perfection is precedented or followed by certain perfection bigger or lesser through lived transitions or passages. So each time it actualizes and reflects the state of All as a cut of Reality while each state of affections, images or ideas can not be separated from the duration which binds it to the precedent state and extends it to following one. Affect is also a term of changes. One affects at the same time it is affected. Exhibitional space as affect (or affectional space) is distinguished from representational and presentational space in the way it attributes movement, produces arrangements and generates new factors of artistic creation including those which are outside of ever accepted artistic elements. The concepts of affectional space are used especially to enlighten contemporary situation of artistic and curatorial processes. Art is no more limited to be seen as mere objects of aesthetical admiration, nor as art vis-$\`{a}$-vis art relationship apart from the whole. It includes possibilities and virtuality that appear in the imperceptible and undescribable manners if delimited in given language. As once noticed by Kuhn, we might be living in a paradigmatically shifting world, not only in Art but also in Life. And we need to express it more with Art as moving and affectional nods than as just a clean window or a distinct manual book.

The Korea Astronomy and Space Science Institute and the Department of Astronomy at the University of Texas at Austin are developing a near infrared wide-band high resolution spectrograph, immersion grating infrared spectrometer (IGRINS). The compact white-pupil design of the instrument optics uses seven cryogenic mirrors, including three aspherical off-axis collimators and four flat fold mirrors. In this study, we introduce the optomechanical mount designs of three off-axis collimating mirrors and one flat slit-viewer fold mirror. Two of the off-axis collimators are serving as H and K-band pupil transfer mirrors, and are designed as system alignment compensators in combination with the H2RG focal plane array detectors in each channel. For this reason, the mount designs include tip-tilt and parallel translation adjustment mechanisms to properly perform the precision alignment function. This means that the off-axis mirrors' optomechanical mount designs are among the most sensitive tasks in all IGRINS system hardware. The other flat fold mirror is designed within its very limitedly allowed work space. This slit-viewer fold mirror is mounted with its own version of the six-point kinematic optics mount. The design work consists of a computer-aided 3D modeling and finite element analysis (FEA) technique to optimize the structural stability and the thermal behavior of the mount models. From the structural and thermal FEA studies, we conclude that the four IGRINS mirror mounts are well designed to meet all optical stability tolerances and system thermal requirements.
