  • 본 연구에서는 녹지계획에 관련된 의사결정을 합리적으로 지원할 수 있요록 GIS(지리정보시스템)와 RS(원격탐사)를 이용하여 서울시 녹지관련 정보에 대한 기본적인 데이타베이스를 구축한 후 녹지 평가지표를 생태 및 환경가치, 이용가치, 사회적여건 가치로 구분 설정하였으며, 이를 이용하여 미시설공원에서의 개발 우선순위를 결정하였다. 또한 이러한 녹지 평가지표들을 서울시 녹지보존 등급부분을 위해서도 활용될 수 있다. 본 연구는 1997년 서울시정개발연구원ㅇ네서 수행한 녹지총량 관리방안 연구의 일부이다.

  • In this paper we developed a method for an optimal planning to reorganize Dong offices to enhance the administrative efficiency. First we defined a mathematical model for the optimal planning problem of reorganizing Dong office and developed a genetic algorithm to solve the problem. For the purpose of minimizing standard deviation of population, area and distance among reorganized offices, the constraints such as allocation, distance, area, population, etc. are considered and weights are applied to Dong offices in the downtown and shopping area. The developed algorithm was applied for reorganizing Dong offices in Jongro Gu, Seoul. The results showed that the developed algorithm could be applied for the real world problem. This study may be applied to the optimal decision of reorganization of offices in the similar reorganization or company M&A situations by changing constraints and weights.

  • To investigate the characteristics of high-ozone occurrences in the Greater Seoul Area(GSA), three high-ozone episodes were selected, for which the ozone warning for concentration above 120 ppb might be issued. The selection was on the basis of morning wind directions and speeds, and daily maximum ozone concentrations measured between 1990 and 1997. The episodes chosen to meet selection criteria were seven days in July 1992, nine days in July 1994, and three days in August 1994, as respectively characterized by southwesterly, easterly, and calm winds in the morning. However, more than 80% of high-ozone days in the GSA were associated with calm winds and the concomitant accumulation of local emission in the morning, rather than being due to transport of ozone or its precursors. This is believed to be the primary reason why ozone concentrations in the GSA varied in a completely different manner even between adjacent monitoring stations. Several premises for initiating research studies for resolving these local variations of ozone concentrations in the GSA are also discussed.

  • In this study, we identify the variables that affect the number of crime and spatial correlation in the Seoul metropolitan area, in addition, we measure the relative risk on the incidence of crime by a Poisson regression model. We suggest a statistical methodology to make a risk map for crime based on relative risk instead of the total event of crime by region using the Geographic Information System. To demonstrate the use and advantages of this methodology, this study presents an analyses of the total crime count in 25 wards in the Seoul metropolitan area.

  • Sulfur dioxide distributions in the Seoul area in 1988 were reproduced by using ISCLT which was the most versatile model among the preferred models recommended by USEPA. Modeling was performed season by season in order to take into account distinct four seasons in Korea. Predicted concentrations were close to the observed ones in most regions, but were different from the observed ones in such regions where the effect of sources outside the Seoul area was important. For better results of the modeling, the modeling domain should be chosen after a careful examination of principal wind directions.

  • The aims of this study is to examine closely the temperature distribution of the solar pond for conditions of Seoul area climate and to prove capability of the solar pond utilization in Seoul area. In this study the equations for the convecting zone temperature of the solar pond were derived from Rabl and Nielsen's model. As the result of computer simulation, it was found that the average temperature of convecting zone is over $100^{\circ}C$ under conditions which is no output and 120cm depth or over of the insulating layer. Consequently if solar pond is constructed in Seoul area, it is a effective heat storage system.

  • ITS(Intelligent Transportation System) is an advanced system which can effectively handle the current transportation problems. DSRC(Dedicated Short Range Communication) is considered as a promising technology since it has the capability of two-way communication and can serves to implement various ITS services. In this paper, we study DSRC based ITS telecommunication traffic analysis and suggest an architecture and network design of telecommunication network for DSRC services. We also perform a simulation study to validate the proposed network architecture and design for Metropolitan Seoul Area with various network alternatives. In this simulation, we use actual traffic data and road characteristics from Seoul area and use our DSRC service configuration.

  • Galaxy clusters, the largest gravitationally bound systems, are an important means to place constraints on cosmological models and study the evolution and formation of galaxies and their large scale distribution. We report results from our study of galaxy clusters in the European Large Area ISO Survey North1(ELAIS-N1) field, covering a sky area of 8.75 $deg^2$. We combine multi-wavelength data from the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey (UKIDSS DXS, JK bands), Spitzer Wise-area InfraRed Extragalactic survey (SWIRE, Optical-Infrared bands), and CFHT (z band). The photometric redshifts are derived from these datasets and are used to search for high redshift galaxy cluster candidates. Finally, we provide new candidates of galaxy clusters at redshifts 1.0

  • The purpose of this study was to predict the spatial housing demand of households in Seoul with the use of residential choice probabilitics. An multinomial legit model is developed using socio-demographic and housing characteristics. SAS package was utilized to estimate this model. This study used the data obtained by the Korea Rosearch Institute for Human Settlemente in 1989. The sample size was 3941 households in Seoul.The residential choice probability varicd depending upon the residential area, head age, head age, tenure and work place. The households with students were more likely to choose kangnam are. The households without young children had higher probability to choose new town near Seoul. Prime reason of this two results were considered the chi Id education and their better housing, Kangnam area was known to be the first consideration for residential choice regardless of work place. Low level of choice probability of kangman area for future residences however, was evidenced. Prime reason of such seemingly contradicting phenomenon is suspected for higher housing prices and limited affordability of people surveyed.

  • The purpose of this study is to explore the status of current ICT convergence technology in the agrifood area through reviewing articles. For this, we classified the ICT convergence technology into four categories including RFID technology, smart sensing technology, USN technology, and other ICT convergence cases and reviewed by extracting the cases related to the convergence technology that is recently conducted depending on each category from the Journal of Computers and Electronics in Agriculture between January 2012 and June 2014. Additionally, by combining the reviews of cases, we conducted the study in the direction of analyzing the recent ICT convergence technology status in the current agrifood area.
