이 연구는 부동산개발사업의 성공에 중점 둔 금융 수요자(GP)와 사업참여에 신중하고 보수성향을 가진 금융 제공자(LP)간의 이익 배분의 합리성을 탐색하는 것이다. 다시 말해서, 부동산 개발사업의 지분 투자자간, 위험의 분배와 그에 비례한 합리적이고 바람직한 개발이익의 배분 구조를 규명하는 것이다. 이 연구는 2가지 관점에서 개발이익의 배분 구조를 분석한다. 첫째, 투자비율에 비례한 이익 배분 구조를 분석하고. 둘째, 허들을 추가한 상태하에서 발생하는 이익배분 구조를 탐색한다. 투자자 간의 투자비율에 비례한 이익 배분은 위험 기피적인 유한책임 투자자의 입장에서는 받아들이기 어려운 구조다. 또한 허들이 많아질수록 무한책임 투자자의 업무성과 향상은 추가수익의 발생으로 유인기능을 한다. 따라서, 부동산개발사업은 상당한 리스크를 수반하므로 워터폴 구조에 의한 무한책임 투자자와 유한책임 투자자의 개발이익 배분의 합리적 결정 모델을 제시한다. This study focuses on the possibility of structuring the business between the GP, which expects the success of the development project, and the LP, who is careful to participate in the project and has a conservative tendency. In other words, it iinvestigates a profit sharing structure between equity investors in a real estate development project and the distribution of risks and the corresponding reasonable and desirable development gains. This research will analyze Choi Hyuk-jae and Jang Hee-soon s existing research in 2020 from two perspectives. First, explore the profit-sharing structure proportional to the investment ratio. Second, we add four hurdles to identify a various profit-sharing structure. Distribution proportional to the investment ratio between each investor is difficult to accept for risk-averse limited liability employees. In addition, the more hurdles are introduced, the more additional promote is generated considering the performance of the general partner, which functions as an incentive design function. Therefore, in a real estate development project where significant risks are inherent, the distribution of development profit between the general partner and the limited partner under the Waterfall structure is inevitable.

Background and Objectives : Most Korean young men should take a military physical examination. This study attempted to search the social, economical and psychological features of Korean youths who have psychiatric problems in taking the military physical examination. So this study was intended to help decide whether the youths enter the military service or not. Materials and Methods : This study analyzed diagnostic features that were grouped by 7 categories (antisocial and borderline personality disorder group, the other personality disorders group, psychosis group, organic mental disorder group, neurosis group, pervasive developmental disorders group, the other groups). The study was conducted from 1994 to May 1999 at Chosun University hospital with about 143 patients who were issued the psychiatric certificate for military affairs. Results : According to the results of the psychiatric examination, the antisocial and borderline personality disorder group had increased more year by year than the other groups. Classified by the residential distribution, the residents of agricultural areas belonged to the psychosis group more than others. Classified by the job distribution, the antisocial and borderline personality disorder group had more gangsters than the other groups. Also the pervasive developmental disorders group included those Who were without an occupation. Classified by visiting companion, those who were included in the antisocial and borderline personality disorder group and pervasive developmental disorders group used to come alone as compared with the other groups. In the case of those who have experienced psychiatric treatment in the past and who have been treated psychiatrically after being given the psychiatric certificate, the psychosis group comprised more than 50% statistically. In the case of the existence of a tattoo and self-injured scars, the antisocial and borderline personality disorder group has more than the others statistically. According to psychological examination, by measure of validity scale of MMPI, the antisocial and borderline personality disorder group appeared as the inverted V shape that L, K value was low and F value was high. And the antisocial and borderline personality disorder group measured by the Pd, Pa measure. Pd, Pa measure value got higher points than the organic mental disorder group statistically. Conclusion : The number of the antisocial and borderline personality disorder patients’ visits increased at the psychiatric hospital year by year and there were many gangsters or persons without regular occupation in that kind of patients’group. And there were many visitors who came by themselves to the hospital. Also they tended to have a tattoo or self-injured scars. And most of patients didn’t do commuting psychiatric care after receiving the psychiatric certificate. In the aspect of the psychological examination, they were likely to exaggerate their symptoms or disguise having psychiatric trouble intentionally.

권장혁,박기태 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.3

Rabson Mendenhall syndrome은 Rabson과 Mendenhall에 의해 1955년 처음 발표된 증후군으로서, 심한 insulin resistance를 보이는 희귀한 상염색체 열성 유전성 질환이다. Insulin receptor의 돌연변이나 insulin이 작용하는 다른 target cell의 결함에 의해 나타나며, 일반적인 증상으로는 흑색가시세포종(acanthosis nigricans), 다모증(hypertrichosis), 손발톱 비대 (onychauxis), 성장 지체 (growth retardation), 성 조숙(precocious puberty), 생식기의 비대, 팽만된 복부(protuberant abdomen), 건성 피부(xerotic skin) 등이 나타난다. 악안면 영역에서는 치아의 이형성, 거친 얼굴의 피부, 하악 전돌, 균열 혀 (fissured tongue)와 같은 특징적 증상이 나타난다. 이에 본 증례에서는 Rabson Mendenhall syndrome으로 본원에 내원한 4세 환아에게 관찰된 치과적 특징들에 관하여 보고하는 바이다. Rabson-Mendenhall syndrome(RMS) is first characterized in 1955 by Rabson and btendenhall. RMS is a rare autosomal recessive variant with insulin resistance. This is due to insulin receptor mutations or other target-cell defects in insulin action. General findings include acanthosis nigricans, hypertrichosis, onychauxis, growth retardation, precocious puberty genital enlargement, protuberant abdomen and xerotic skin. Characteristic oral and maxillofacial findings include dental dysplasia, coarse facial skin, prognathic jaw and fissured tongue. In this case report, dental characteristics of a 4-year old boy with Rabson-Mendenhall syndrome are described.

Air quality monitoring is a primary activity for industrial and social environment. The government identifies the pollutants that each industry must monitor. Especially, the VOCs(Volatile Organic Compounds), which are very harmful to human body and environment atmosphere, should be controlled under the government policy. However, the VOCs, which have not been confirmed in emission sources are very difficult to monitor. It is needed to develop the monitoring system that allow the continuous and in situ measurement of VOCs mixture in different environmental matrices. Gas chromatography and mass spectrometry are the most prevalent current techniques among those available for the analysis of VOCs. But, they need a large size analytical instrument, which costs a great deal for purchase and operation. In addition, it has some limitations for real time environmental monitoring such as location problems and slow processing time. Recently, several companies have commercialized a portable VOCs measurement systems, which cannot classify various kinds of VOCs but total quantities. We have developed a VOCs measurement system, which recognizes various kinds and quantities of VOCs, such as benzene, toluene, and xylene(BTX). Also, it can be used as a stand-alone type and/or fixed type in the vehicle with rack for real-time environmental monitoring.

LAN 환경에 적합한 저비용 고효율 스트림 서비스 알고리즘

홍현기,장혁수 明知大學校 産業技術硏究所 2002 産業技術硏究所論文集 Vol.21 No.-

Most stream servers currently in use are developed for WAN (Wide Area Network) or Internet to serve live video and VOD (Video On Demand) images. They are large in size and expensive, but not scalable to meet growing user requests. So, the users have to purchase more powerful, but expensive servers. However, many schools and institutions are not affordable to buy them, which are in fact too powerful for their LAN environments. This paper proposes a cost-effective algorithm which works efficiently in LAN environments. Each host of an institution belongs to a group in which a server is responsible for transmitting all the required services to the client hosts internally within the same group as well as to the remote servers externally. Once the remote server gets the services from the original server, it retransmits them to its members. As a result, it can reduce significant amounts of traffic and utilize the network resources more efficiently.

인트라넷에서 멀티미디어 생방송 서비스를 제공하기 위한 효율적인 멀티캐스트 알고리즘

김대수,장혁수 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

Many of the multicast applications such as video broadcasts and teleconferencing need to support dynamic multicast sessions wherein the membership of the multicast group changes with time. Most existing multicast servers require layer 3 or layer 4 switches to support dynamic multicast sessions, thou호 the switches are not affordable to the small and medium size organizations such as colleges. In this paper, we propose and algorithm to provide live multimedia service without the switches.

에이전트 기반의 침입 탐지 방안 연구

Abstract - The Intrusion Detection System is for protecting the system from the intruder by realizing the system's vulnerability and getting rid of the cause in the short time. Most of the Intrusion Detection Systems which are operating the Firewall are powerful to protect the system against the external intruder. But they don't work very well to the internal intruder. Although host-based vulnerability analysis is necessary for inspecting and analyzing the system's vulnerability, it is impossible to manage all of the host system. To get rid of those problems, we use the Mobile Agent. But to use the same agent to every application sever is the squandering of its function, a waste of time for analyzing and searching the data, and the deterioration of network bandwidth's efficiency. In this paper, we installed the functional agent to the network's inside of the Intrusion Detection System. After installing the lightweight agent at the specific application, we can obtain the good result of management by using the Mobile-Agent Model. For the proof, we made a comparison Client-server Model of the Remote Procedure call and Mobile-Agent Model.

핸드오프가 빈번히 발생하는 마이크로 셀룰러 시스템에서 제한된 주파수 자원을 보다 효율적으로 사용하고자 하는 알고리듬들이 제안되어 왔으나 핸드오프를 위해 사용자의 실제 이동 방향에 관계없이 주위 셀 모두의 핸드오프 용 주파수를 예약하는 방식이 주로 사용되었고 그것은 주파수 자원의 낭비를 초래하여 왔다. 본 논문은 사용자의 이동 방향 및 속도가 고려된 벡터 파라미터를 사용하여 실제 이동 방향과 관계 있는 셀에 대해서만 핸드오프 용 주파수를 예약하는 방식을 제안하고 성능분석을 통하여 주파수 자원을 절약할 수 있음을 보여준다.

모든 호스트에서 사용 가능한 생방송 스트림 서버 모듈 개발에 관한 연구

홍현기,장혁수 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

Most existing stream servers set up a new independent session as a new request arrives from and end user. They are to be equipped with relatively expensive layer 3 or switches to support more users, though the switches are not affordable in most small and medium scale institutions such as colleges and K-12 schools. We develop a live stream server module which could be implemented/ported in any hosts in small and medium size intranet. Once the module is implemented in any hosts, the hosts can be a server regardless of their location in the intranet and the expensive layer 3 or 4 switches are not necessarily needed in the server.
