오늘날 인터넷은 하나의 거대한 분산 정보 서비스센터의 역할을 수행하며 여러 가지 많은 정보들과 이를 관리 운영하는 데이터 베이스 서버들은 분산된 네트워크 환경 속에서 광범위하게 존재하고 있다. 그러나 우리는 데이터 특성에 따라 입력 데이터를 처리할 서버를 결정하는데 여러 가지 어려움을 겪고 있다. 본 논문에서는 분산 환경 속에 존재하는 수많은 데이터들 가운데 신경망을 이용해 입력 데이터 패턴을 가장 효율적으로 처리할 수 있는 목적지 서버를 마이닝하는 기법과 이를 기반으로 한 지능적 데이터 마이닝 시스템 구조를 설계하였다. 그 결과로서 새로운 입력 데이터패턴이 신경망으로 구현된 동적 바인딩 방법에 따라 목적지 서버를 결정한 후 처리됨을 보였다. 이 기법은 데이터 웨어하우스, 통신 및 전력부하패턴 분석, 인구센서스 분석, 의료데이터 분석에 활용될 수 있다.

인구센서스와 같은 국가 통계정보는 국가의 미래 투자계획과 정책수립을 위한 중요한 기초데이터이다. 그러나 데이터의 코딩과정이 모두 수작업으로 이루어지기 때문에 결과의 일관성 결여와 시간과 인력이 너무 많이 소요된다는 것 등이 문제점으로 지적되고 있다. 따라서 본 연구에서는 한국 산업표준 분류표에 근거한 자동코딩시스템을 개발하여 코딩과정을 수작업으로 처리할 때 발생하는 문제점을 해결하였다. 시스템의 지식베이스로는 학습이론을 사용하여 저자가 새로이 개발한 복수의 전거어 사전들을 활용하였다. 실험한 결과, 생성률은 99.5%를, 정확률은 83.3%라는 결과를 얻었다. 따라서 이 시스템은 실제 통계데이터의 자동코딩과정에 사용될 수 있으며, 국가 통계정보의 효율적 분석에 매우 유용하게 사용될 수 있을 것이다.

The purpose of this study is to develop Water Quality Management System(WQMS), which performs calculating pollutant discharge and forecasting water quality with water pollution model. Operational water quality management requires not only controlling pollutants but acquiring and managing exact information. A GIS software, ArcView was used to enter or edit geographic data and attribute data, and MapObject was used to customize the user interface. PCI, a remote sensing software, was used for deriving land cover classification from 20 m resolution SPOT data by image processing. WQMS has two subsystems, Database Subsystem and Modelling subsystem. Database subsystem consisted of watershed data from digital map, remote sensing data, government reports, census data and so on. Modelling subsystem consisted of NSPLM(NonStorm Pollutant Load Model)-SPLM(Storm Pollutant Load Model). It calculates the amount of pollutant and predicts water quality. This two subsystem was connected through graphic display module. This system has been calibrated and verified by applying to Mokhyun stream watershed.

The Great Famine may have had a continued impact on the population structure of North Korea even after the crisis subsided ten years ago. However, there is a significant gap between what has been said about the country and what data indicates. This gap seems inevitable mainly because reliable data are seriously lacking and access is restricted for most scholars outside the country. Yet, it is only reasonable to question why most studies have failed to explain the causality between the Great Famine and accumulated changes in the population of North Korea. In this regard, a recent study conducted by Korean demographers (Jeon et al., 2015) have several implications on the importance of accurate and reliable data when the study involves such rare and scarce information. This paper explores the changing trends of the population structure in North Korea providing a review of recent studies on demographic issues associated with North Korea and offers suggestions on understanding the post-famine effect on the overall changes in the population of North Korea.

The purpose of this explanatory study was to provide baseline information on the secondary prevention health behavior of cervical cancer in Korea which was related to the utilization of the Papanicolaou (Pap) smear screening test. The secondary data from the 1992 Korean Health Behavior Survey was used for analysis in order to determine sociodemographic profiles and the predictor variables. The sample analyzed for this study contained 1,489 Korean women residing in Korea aged 20-59 selected by multi-stage sampling method from the 1990 Korean census. Univariate, bivariate, and logistic regression analysis were performed to produce the findings of this study. Only 27.9% of the study sample had had a Pap test in 1992. It was found that the relative sociodemographic profiles of the Pap test between users and non-users were distinctive. The predictors variables were age, marital status, educational status, usual source of care, perceived household economic status, health check-up, and presence of chronic diseases

This study proposes an algorithm for recognizing apple trees in images and detecting apples to measure the number of apples on the trees. The proposed algorithm explores whether there are apple trees or not based on the number of image block-unit edges, and then it detects apple areas. In order to extract colors appropriate for apple areas, the CIE $L^*a^*b^*$ color space is used. In order to extract apple characteristics strong against illumination changes, modified census transform (MCT) is used. Then, using the AdaBoost learning algorithm, characteristics data on the apples are learned and generated. With the generated data, the detection of apple areas is made. The proposed algorithm has a higher detection rate than existing pixel-based image processing algorithms and minimizes false detection.

Institutional repositories (IR) are promising to be extremely advantageous to scholars especially in developing countries. IR initiatives started in India during the late nineties and the popularity of this concept is growing rapidly in the higher educational and research institutions to disseminate newly emerging knowledge and expertise. The purpose of this paper is to critically analyze the network links of IR websites among four IITs that are registered in open DOAR (Directory of Open Access Repositories) web portal. The Institutional Repositories chosen for the study are IIT Delhi, IIT Hyderabad, IIT Bombay, and IIT Kanpur. The analysis of the study focused on standard graph and network cohesion metrics, such as density, diameter, eccentricity and distances, and clustering coefficient; for an even more detailed analysis advanced centrality measures and fast algorithms such as clique census are used.

The main purpose of this study was to identify the impact of neighborhood settings on peer risks experienced by delinquent adolescents. A convenience sample of 1,086 youth who came to the attention of four county juvenile courts was used for the present study. The peer risk levels were measured through use of version 1.0 of the Global Risk Assessment Device (GRAD); in addition, neighborhood information obtained from the National Census was utilized. The results of the HLM demonstrated that there were significant between-neighborhood variations in peer risks and the neighborhood economic disadvantage variable was associated with peer risks after controlling for the variables of individual characteristics. The findings of this study add to the literature on juvenile delinquency by providing empirical support for the proposed model that illustrates the significant relationship between a neighborhood setting indicator and peer risks experienced by delinquent adolescents when practicing treatment or intervention programs with delinquent adolescents.

This study is to investigate that population change as a result of the decline in population has a correlation with a decrease in crime, with the change in the demographic composition by comparing with two models: model with growth in population and one with the decline in population. We collected demographic data for all cities in Korea from the 2010 Census to 2020 offered by the Korean Statistical Information Service, with crime data comprising serious reported crime events from the Korean Nation Police Agency through requesting data related to the total number of crimes at the same as the period of demographic data. This study can identify the impacts of demographic changes as a result of population change on crime change through a comparative analysis between areas with population growth and ones with population decline. We can confirm that there are differences in determinants of crime between areas with population increase and one with population decrease from the analysis of the impact of demographic change as a result of population change on crime change.
