  • Purpose: The purpose of this study was intended to examine the importance and role of social capital in the local community, and empirically identify the relationships among the social capital, community spirit, resident satisfaction, and community participation of the residents of urban-rural complex areas. Methods: This study conducted a survey was conducted with residents of the urban-rural complex areas to collect data, and the data were statistically and empirically analyzed to verify the hypothesis. Results: As a result of the study, first, networks and trust as local social capital were found to have positive effects on local attachment. Second, networks and trust were found to have positive effects on social ties. Third, local attachment and social ties were found to have positive effects on resident satisfaction. Finally, community participation was found to have moderating effects on the relationship between social ties and resident satisfaction. Conclusion: Through this study, the importance and role of local social capital in urban-rural complex areas, where regional problems are highly likely to occur, were reviewed, and basic data necessary to solve the social problems at hand in urban-rural complex areas and promote continuous development were provided can be said to be the significance of this study.

  • Most of the real world phenomena change over time. The ability to represent and to reason geographic data becomes crucial. A large amount of non-standard applications are dealing with data characterized by spatial, temporal and/or uncertainty features. Non-standard data like spatial and temporal data have an inner complex structure requiring sophisticated data representation, and their operations necessitate sophisticated and efficient algorithms. Current GIS technology is inefficient to model and to handle complex geographic phenomena, which involve space, time and uncertainty dimensions. This paper concentrates on developing a fuzzy spatio-temporal data model based on fuzzy set theory and relational data models. Fuzzy spatio-temporal operators are also provided to support dynamic query.

  • In order to raise the accuracy of meteorological data, several numerical experiments about the usefulness of data assimilation to prediction of air pollution was carried out. Used data for data assimilation are surface meteorological components observed by Automatical Weather System with high spatial density. The usage of surface data assimilation gives changes of temperature and wind fields and the change caused by the influence of land-use on meterological simulation is more sensitive at night than noon. The data quality in assimilation it also one of the important factors to predict the meteorological field precisely and through the static IOA (Index of Agreement), simulated meteorological components with selected limited surface data assimilation are agree well with observations.

  • To the success of the megaproject including various and complex facilities, it is needed to establish a database system. Developments in data collection, storage and extracting technology have enabled iPMIS to manage various and complex information about cost and time. Especially, when we consider that both the go and no go decision in feasibility, Cost is an important and clear criteria in megaproject. Thus, Cost data modeling is the basis of the system and is necessary process. This research is focus on the structure and definition about CBS data which is collected from sites. We used four tools which are Function Analysis in VE, Casual loop Diagram in System Dynamics, Decision Tree in Data-mining, and Normalization in SQL to identify its cause and effect relationship on CBS data. Cost data modeling provide iPMIS with helpful guideline.

  • 이 연구는 산업단지의 효율적 운영 방안 마련의 기초연구로 우리나라 산업단지의 상대적 효율성 수준을 측정하고, 다양한 유형별 차이를 분석하는데 목적이 있다. 이를 위해서 2017년 기준 287개의 산업단지의 생산액과 수출액을 산출변수로, 산업용지면적과 종사자수를 투입변수로 자료포락분석(Data Envelopment Analysis; DEA)을 적용하였다. 분석결과, 우리나라 산업단지의 상대적 효율성은 주로 단지유형과 운영기간에 따라 영향을 받는 것으로 분석되었다. 단지유형 측면에서는 도시첨단산업단지가 가장 높게 나타났으며, 다음으로 국가산업단지, 일반산업단지의 순으로 분석되었다. 따라서 산업단지의 효율성을 확보하기 위해서는 산업단지 업종의 첨단화와 물리적 규모의 확대가 필요할 것으로 판단된다. 또한 산업단지 운영기간이 증가함에 따라 산업단지의 상대적 효율성이 높아지고 있고, 노후산업단지의 상대적 효율성이 그렇지 않은 산업단지에 비해 높게 분석되었다. 이러한 결과는 효율성이 확보된 노후산업단지의 경우 재생의 효과가 극대화될 수 있기 때문에 노후산업단지의 재생사업 우선순위 선정에 있어 하나의 고려요소로 적용할 수 있을 것이라 판단된다.

  • 우리나라 제조업 성장을 견인해 온 산업단지는 지역 단위에서 제조업 집적의 외부효과를 강화하는 수단으로서 기능하는가? 본 연구는 질문의 답을 위해 제조업 집적과 지역경제 생산성 간 관계에서 산업단지 조절효과를 분석함으로써 기존 선행연구에서 다루지 않은 집적효과 논의를 수행하였다. 2010-2019년 기간의 전국 시군구를 대상으로 한 불균형패널자료를 활용하여 패널분석을 실시하였으며, 전국, 수도권 그리고 비수도권을 구분하여 추정한 결과를 제시하였다. 분석 결과 비수도권의 경우 제조업 특화와 다양성 증가에 따른 긍정적 외부효과가 산업단지를 통해 더욱 강화되어 나타나는 환경이 조성된 반면 수도권에서는 산업단지의 조절효과가 제한적인 것으로 나타났다. 이러한 결과는 제조업 집적효과 극대화, 비수도권의 경제 활성화, 제조업 혁신을 위한 정책수단으로서 산업단지 역할을 재조명할 수 있는 측면에서 시사하는 바가 크다.

  • National-wide and/or large scale sample surveys generally use complex sample design. Traditional Pearson chi-square test is not appropriate for the categorical complex sample data. Rao-Scott suggested an adjustment method for Pearson chi-square test, which uses the average of eigenvalues of design matrix of cell probabilities. This study is to compare the efficiency of Rao-Scott first order adjusted test to Wald test for homogeneity between two populations using 2009 Gyeongnam regional education offices's customer satisfaction survey (2009 GREOCSS) data. The 2009 GREOCSS data were collected based on stratified three-stage cluster sampling with probability proportional to size. The empirical results show that the Rao-Scott adjusted test statistic using only the variances of cell probabilities is very close to the Wald test statistic, which uses the covariance matrix of cell probabilities, under the 2009 GREOCSS data based. However it is necessary to be cautious to use the Rao-Scott first order adjusted test statistic in the place of Wald test because its efficiency is decreasing as the relative variance of eigenvalues of the design matrix of cell probabilities is increasing, specially more when the number of degrees of freedom is small.

  • This study was initiated to improve of the defect investigation method using event data recorders (EDR) and suggested a solution through the regulation and system analysis of EDR. The EDR data has been used for various purposes such as the vehicle defect investigation and the traffic accident investigation. However the EDR regulation has not been updated since the implementation in 2012. "Trigger Threshold" can be used to analyze a single accident such as the frontal crash, the side crash, and the rollover. In the case of a complex accident in which a rollover accident and a crash accident occur simultaneously, it is difficult to analyze a complex accident due to current "Trigger Threshold". This study proposed the method of separating the "Trigger Threshold" into a crash accident and a rollover accident so that accidents can be analyzed using the EDR data even when a complex accident occurs. In addition, it proposed the improvement method to quickly use the data of EDR in accident reconstruction software.

  • This study analyzes interior features of indoor community facilities, focused on apartment complexes in capital area selected by 'Award of best living apartment' during $2000{\sim}2007$. First we analyze community facilities' concept, present standards of installment, present condition, then the size of each complex compared with legal standards. Also, we analyze interior features(spacial layout, furniture and furnishings, interior finishing materials, interior color), too. Research methods included both data survey and site visiting inquiry. Data survey method analyzes size of each complex using community facilities' floor plans, and site visiting inquiry analyzes type and feature of community facilities. Survey target was total 11 complexes, 7 in Seoul, 4 in Gyeonggi-do. The result is as follows. 1) It is needed to improve legal standards of installment, and to provide space with flexibility and changeability in order to allow alternation of usage purpose by resident's claim. 2) To determine size of community facilities, we must planned not only by the number of households, but by legal standards of supply according to the number of households, the rate of net area, and the recommended size per person. 3) The area of community facilities in apartment complex that residents use doesn't considered user's convenience. So it us needed to add each facility's recommendation in response to user's needs.
