For integrating and utilizing the statistical data, which is summarized by arbitrary areal unit such as demographics, with stellite imagery or other GIS data, areal unit of both data should be accorded. Dasymetric mapping is proposed as a useful method fur disaggregating the aggregated statistical data to finer areal unit or generating surface model from object data such as polygonal area. This research evaluate the effectiveness of dasymetric mapping by 1) summarizing the yellow page information by administrative district, 2) modeling the business density using dasymetric mapping, and 3) comparing the business densities of raw data and that of spatial interpolation result.

In this study, risk categorized five safety management elements(equipment and structure, evacuation, lifesaving and fire extinguishing, performance based fire safety plan, operations management) were classified in order to establish safety system of underground space. Using classified safety management elements, assessment of fire hazard was performed. After calculating the grade of evaluation categories, assessment of fire hazard was suggested. The three grades of evaluation categories are classified as to importance and four criteria of evaluation are classified as to check result based on subdivisions.

The purpose of this study was to carry out a comprehensive assessment of Donjibong Park in Daegu and establish a master plan for green space considering the functional characteristics of the park. For this purpose, green space in the park was assessed based on 13 indicators using three functions. A comprehensive green master plan was then proposed. Green spaces with high scores for the natural-ecological and environmental-control functions were found in the central area of the park, whereas green spaces with low scores were found near the park boundary and paved areas. Green spaces in the southeast were found to have a high score for usage functions due to their proximity to a residential area. In the master plan based on the comprehensive assessment, the plan space was divided into a conservation area, restoration area, buffer area, environmental monitoring area, observatory/trail/facility area, and waterside green space area. Also, concrete plan directions were proposed based on each plan space. These results can be utilized for establishing objective plans in the future construction of new parks.

가상학습은 지식 정보화시대를 맞이하여 국내외으로 새로운 교육훈련 패러다임으로서 시간과 공간을 초월한 얼린 학습공간으로 부각되고 있다. 특히 정보처리 기술의 급속한 발전으로 국내외 각종 정규·사회 교육기관에서는 인터넷을 이용한 가상학습 교육훈련을 전극 도입하고 있는 추세이다. 가상학습을 기반으로 하는 코스웨어 개발이냐 학습평가에 관한 연구는 많으나 품질평가에 관한 연구는 아직까지 미비하여 본 논문에서는 가상학습 지원시스템의 품질평가 모델을 제시하여 교육 현장에서 가상학습 지원시스템 구축 시 품질평가 기준으로 활용하고자 한다.

This paper will specify geo-objects and geo-fields of the geo-ecological contamination source and implement the system for evaluating an ocean Environmental contamination based on the spatial statistical analysis. In order to produce the grade of fishery that can evaluate the ocean effect, we will analysis the degree of the spatial correlation by semi-veriogram and predicate the elevation raster of spatial data using ordinary kriging method. This paper is to estimate the grade of fishery contamination region and produce the ratio of the area according to the fishery grade. Therefore, we can contribute to produce fishery grade that evaluates the ocean effect by means of deciding an efficient fishery environment.

21세기 정보화 시대의 도래와 함께 반도체 및 디스플레이 분야는 고부가가치산업으로 급격히 성장하였고, 현재까지도 미래의 지속적인 시장 창출을 위하여 기술개발과 투자로 초미세화, 고효율, 대면적화에 대한 원천기술 확보가 중요시되고 있다. 반도체 및 디스플레이의 대면적화가 진행됨에 따라 플라즈마 공정장비의 대면적화도 활발히 기술개발이 진행되고 있으며, 대면적화에 있어 플라즈마의 공간균일도는 생산수율 및 공정균일화를 위해 기본적으로 평가되어야 하는 중요한 지표가 되었다. 하지만 종래의 진단법들은 대면적 플라즈마 진단에 매우 제한적이기 때문에 본 연구에서는 대면적 플라즈마의 공간균일도 평가를 위해 플라즈마의 방출광 측정을 기초로 하는 진단계를 개발하였다. 플라즈마 방출광을 이용한 진단은 플라즈마에 섭동을 주지 않고 전자온도의 변화 및 공간균일도를 평가할 수 있다. 이 진단법은 두 마주보는 한쪽 면이 평평한 볼록렌즈(plano-convex lens)로 이루어진 수광시스템과 역변환 알고리즘을 통해 선 적분된 방출광으로부터 플라즈마 방출광의 국지적 정보를 측정하는 것이다. 플라즈마와 같이 크기가 큰 광원의 경우 렌즈 광학계에서 필연적으로 수반되는 선적분된(chord-integrated) 방출광을 제거하기 위해 구조에 따른 시스템 함수를 이용한 푸리에 변환 알고리즘을 개발하였고, 이를 통해 렌즈 초점거리의 정확한 방출광 세기만 재구성하였다. 이러한 재구성 방법을 이용하여 렌즈의 거리를 움직이며 대면적 플라즈마의 방출광 분포측정을 수행하였고, 이에 대한 결과를 발표하고자 한다.

A multi-scale database is a set of spatial database, covering same geographic area with different scales and it can be derived from pre-existing databases. In the derivation processes of a new multi-scale spatial database, the geometries and topological relations on the source database can be transformed and the transformation can be the cause of the lack of integrity Therefore, it is necessary to assess the transformation whether it is consistent or not after the derivation process of a new multi-scale database. Thus, we propose assessment methods for the topological consistency between a source database and a derived multi-scale database in this paper. In particular, we focus on the case that 2-dimensional objects are collapsed to 1-dimensional ones in the derivation process of a multi-scale database. We also describe implementation of the assessment methods and show the results of the implementation with experimental data.

This study investigates the influence of the attractive dining space on customers' restaurant evaluation, using an experiment research method. It also examines whether the perceived risks in purchasing and the affect intensity moderate the effect of the attractive dining space on the restaurant evaluation. Service quality and purchasing intention are set up as a dependant variable in oilier to figure out the effect of the dining space. The summary of the research result is as follows. First, an attractive dining space induces more positive evaluation of service quality and increases purchasing intention. Second, an attractive dining space has more significant influence on the service quality and the purchasing intention of customers in the purchasing situation of high level of perceived risk than in the purchasing situation of low level of perceived risk. Third, it is shown that personal variable such as affect intensity moderates the effect of an attractive dining space on the service quality perception and the purchasing intention.

The purpose of this study is to develop and implement a process-based evaluation program with the theme of school space design in the housing area of the middle school home economics. In order to achieve For thispurpose, a process-based evaluation program based on the theme of school space design was developed following the ADDIE instructional design model, and the program was executed to a total of 93 students. A questionnaire survey and in-depth interview were conducted for the evaluation of the program. The results of this study are as follows. First, based on the results of a 2015-Revised Curriculum analysis, a school space design program evaluation plan was established, and two evaluation tasks were developed. Accordingly, scoring criteria were prepared and 8 evaluation materials for students and 2 evaluation materials for teachers were developed. A total of 9 sessions were developed for teaching and learning activities and evaluation-linked operation procedures to perform evaluation tasks. As a result of an expert validity test for the program, all items were verified to be appropriate in content validity and content composition with an average of 3.6 to 4 points (4 points). Second, after conducting the school space design program, a survey on students were conducted, and as a result, all three areas of school space design class, process-based evaluation, interest scored high in average scores of 4.12 to 4.27 out of 5. According to the survey and interview results, the program provided new learning opportunities for school space design, the students were able to reach the suggested achievement goals, and the self-assessment, peer evaluation and teacher feedback positively affected the students during the learning process so that they could reflect on their learning and actively participate in the subsequent learning activity. This study has a limitation in generalizability in that the program was conducted on a limited number of students, and future studies are expected to expand the scope in terms of research participants, evaluation criteria, and school space design classes. This study laid the foundation for theory and practice by developing and implementing a process-based evaluation program for home economics education, and it has contribution in that it suggested the possibility that teachers and students can take the initiatives in school space design, focusing on the housing content elements of home economics.
