The thesis intents to analyze typological arrangement of community facilities in apartment housing complex. According to the arrangement of community facilities, It trys to analyze on how high convenience and comfortableness is for apartment housings, to arrange and classify the typology of arrangement, and to propose a plan of improvement. This study is made by comparison of a rental apartment and a newly-built apartment for sale in order to investigate and analyze on the case of the apartment housings that Korea National Housing Corporation provided for Busan, based on the result according to the typology of complex arrangement of community facilities classified as the concentrated type and the dispersed type. As a result, the newly-built apartment for sale has a high use ratio in the aspect of quantity and quality of community facilities compared to that of the rental apartment. 오늘날의 도시의 주거는 인간생존과 존재 가치에 직접 연결된 물리적,사회적,문화적 장치로서 자리매김해 왔다. 도시주거를 계획 공동주택 커뮤니티시설 배치의 뮤형 분석에 관한 연구 하면서, 흔히 ‘주거요구를 만족시키는 집’이 라는 말을 사용한다. 사용자 즉 거주자의 욕구 충족과 더불어 생존과 복리까지도 포함하는 포괄적이 개념이라 할 수 있을 것이다. 도시의 주거는 시공간적 실체와 인식,사회의식,상징,가치,문화체계까지도 막대한 영향력을 결정하고 있다 이러한 측면에서 우리는 인간의 경험세계를 지배하려 들고 거주자의 자율과 창의를 억누르고 있는 상태에 도달하 게 되었다. 특히 도시주거의 대표적인 공동주택의 경우 계량적 지표와 기술적 기준,형식적 절차와 법 규정, 전문규범 언어와 계획원리 지침과 같은 각종 체제구조에 의해 개발되고 있다.

Since having enacted the law related to the private financing about social overhead capital legislated in October 1994, the private financing projects have been settled down as the critical procedures to provide the social infrastructure. The private financing projects might not only benefit those social infrastructures such as school, welfare, and cultural facilities which need to be invested as quickly as possible in order to meet public demands, but it will lead private investment and make various private project procedures available provided that the BTL projects are activated properly in the field of education, welfare and train infrastructures. As a result of those market conditions of private financing projects, the procedures have been expanded to the newly confirmed projects and expected to hold the potential market size which might be equal to the BTO. Despite those beneficial factors, the steps reporting how to perform those projects, which one will be selected, and how to evaluate those proposals in Parliament are very complicated and difficult to go through. Consequently, the purpose of this study is to figure out the problems derived from BTL projects when compared with the traditional procedure in an educational area, and then provide the guideline to perform BTL projects efficiently and properly.

韓國語 /子音+母音/形態의 PITCH分析

金明起,安點榮 동아대학교 공과대학 부설 한국자원개발연구소 1985 硏究報告 Vol.9 No.1

This paper describes an analysis method for the pitch periods of Korean /consonant+vowel/type pronounced by a male speaker. After sampling the voiced speech at a sampling rate of 10㎑, we stored these data in the memory of the microcomputer through the 8 bit A/D converter. An algorithm was used for center-infinite peak clipping and simplified autocorrelation analysis to detect the pitch period. As a result of experiment, it shows that the pitch period of Korean speech is changed variously depending on the kinds of consonant and vowel.

Population is concentrated urban region in Korea. It is leading to over-massed dwelling of urban region and was made worse by the residential environment. This study is comparison of population density by the city size of the Master Plan in Korea. Analytical method decide ranking at thirty-five cities of Korea by the census in 1975 and it divided into city size which is Metropolis (over a million), Large City (300-1,000 thousand), Middle Town (100-300 thousand) and Small Town (under 100 thousand persons). In this study, population density for possible developing area was computed by the presumption of population in 1986. The results of this study are summerized as follows: 1). Population plan was underestimated in Metropolis (Seoul, Busan and Daegu) by policy agreement. 2). The possible developing area's population density will proper in under-a million's city. 3). The Metropolis cause an advance in the population density of possible developing area in 1936 and will bring about a change for the worse of residential environment. (362persons/ha.) 4). A plan of solution to a population density's rising is necessary re-enforcement of re-completed master plan and the plan of arrangements for residential area must be considered in the plan of re-completed master plan.

정명덕,김민호,변건식 동아대학교 공과대학 부설 한국자원개발연구소 1995 硏究報告 Vol.19 No.1

For FH-SS communication, We discussed the method of indirect synthesizer in several methods. The problem of single frequency synthesizer using with PLL is a varied coefficient value of damping factor in frequency hopping time, which is caused unstable frequency. So, for stable frequency synthesizer, a coefficient of damping factor must be optimized and synthesized to be removed excessive response time. In this paper, we studied FH using with 2 loop frequency synthesizer which takes stable frequency, we made up simulator and had a good performance(real time speed).

확률적 위험도 분석모형을 이용한 공동주택 재건축 사업의 수익성 예측모델 개발

우광민,이학기 東亞大學校 工科大學 한국자원개발연구소 2007 硏究報告 Vol.30 No.2

Recently, Apartment Reconstruction Projects are performing only with the basis of profitability without establishing either certain criteria or standard guideline. In addition, the profitability information contained in a disposal plan tends to be considered as a fixed valve, and it is frequently changeable because reconstruction projects have such a long time to complete and many participants with respective interests. s mentioned above, the new approach needs to be developed which covers the limitation of the unvaried one. Consequently, this study focuses on the probability approach considering not only variances that ffect the profit, but the relationship between profit and risk, and then is modeling. his study is anticipated to improve the reliability and accuracy of expected value as well as pply to the decision making criteria quantitively about potentially hidden risks in that projects. 아파트 재건축사업은 신규주택의 공급과 주거환경의 개선이라는 긍정적인 측면과 함께 고밀도 개발을 통해 높은 수익성을 기대 할 수 있어 활발히 추진되어 왔다. 그러나 최근 저밀도단지의 감소와 함께 주택시장의 안정을 위해 발표된 일련의 부동산안정대책들이 재건축 사업을 중심으로 규제를 강화함에 따라 수익성이 크게 악화되어 재건축사업의 추진과 관련한 제반 환경이 점차 나빠지고 있다. 한편 공동주택 재건축사업은 비전문가들 로 구성된 조합이 사업주체가 됨에 따라 의사결정의 비전문성에 의한 사업지연,사업주체들 간의 분쟁,그리고 비용 상승과 같은 많은 문제점을 발생시키고 있으며,사업시행절차가 복잡하고 사업기간이 길며,많은 사업주체들이 참여하기 때문에 일반적인 신축사업에 비해 불확실성이 큰 사업이다.그러나 현재 재건축사업은 추진 의사결정과 관련한 확정된 지표나 기준이 없이 막연한 수익성에 대한 기대를 토대로 시행되고 있으며,사업시행과정에서 직면하게 되는 제반 위험에 대해 경험적으로 대응하고 있는 실정이다. 또한 재건축조합이나 시공예정회사들이 제공하는 관리처분에 관한 정보는 결정론적 분석을 통한 단순한 예측에 불과하여 재건축을 시행하는 과정에서 결과가 수정되는 것이 일반적이다. 즉 수익성에 대한 예측이 재건축시행 과정상의 유동적인 상황에서 변경됨에 따라 예측결과에 대한 신뢰도는 근본적으로 내•외적인 한계를 갖고 있다. 이러한 결정론적 접근방식이 갖는 한계를 복하고, 예측의 신뢰성과 정확성을 확보하기 위해선 재건축사업의 수익성에 영향을 미치는 변수들의 변화와 이에 따른 수익과 위험의 상관관계를 구조화할 필요가 있다.

Development and Research of Odorant Sensor by using Lipid-coated Quartz Crystals

Kwon, Young-Soo,Chang, Sang-Mok 동아대학교 공과대학 부설 한국자원개발연구소 1993 硏究報告 Vol.17 No.1

At-cut quartz crystal has been applied as chemical vapour sensors. The responses of quartz crystal at 9 MHz coated with phosphatidylglycerol(PG), phosphatidylinositol(PI), phosphatidylethanolamine(PE), phosphatidylserine(PS), and lipid A(LA) were determined for amyl acetate, acetoin, menthone and other organic gases, which showed different affinities for each lipid. The identification of odorants depending on the species of lipid used for coating is discussed in terms of the normalized resonant frequency shift pattern.
