The purpose of this study is for the fundamental understandings about building morphological parameters and aerodynamic roughness parameters of Seoul, Korea using the detailed urban geographic information datasets. Applied roughness parameter calculations are based on a digital map of buildings with lot area polygons. The quality of the developed roughness length ($z_0$) of Seoul was evaluated with densely installed 107 automatic weather stations. The correlation coefficient results between averaged wind speeds of AWS data and averaged $z_0$ is -0.303 in night and -0.398 in day (200 m radii circles case). Further $z_0$ enhancement should follow by considering other surface features such as high tree and orography of Seoul. However, this study would meet the needs to for local- or meso-scale meteorological modeling applications of Seoul. However, further studies would require for enhancing the $z_0$ applications of Seoul.

The International HapMap Project and the Human Genome Diversity Project (HGDP) provide plentiful resources on human genome information to the public. However, this kind of information is limited because of the small sample size in both databases. A Genome-Wide Association Study has been conducted with 8,842 Korean subjects as a part of the Korea Association Resource (KARE) project. In an effort to build a publicly available browsing system for genome data resulted from large scale KARE GWAS, we developed the KARE browser. This browser provides users with a large amount of single nucleotide polymorphisms (SNPs) information comprising 1.5 million SNPs from population-based cohorts of 8,842 samples. KAREBrowser was based on the generic genome browser (GBrowse), a web-based application tool developed for users to navigate and visualize the genomic features and annotations in an interactive manner. All SNP information and related functions are available at the web site http://ksnp.cdc. go.kr/karebrowser/.

Recently, the demand to interpret image data with artificial intelligence in various fields is rapidly increasing. Object recognition and detection techniques using deep learning are mainly used, and video integration analysis to determine unstructured object recognition is a particularly important problem. In the case of natural disasters or social disasters, there is a limit to the object recognition structure alone because it has an unstructured shape. In this paper, we propose intelligent video integration analysis system that can recognize unstructured objects based on video turning point and object detection. We also introduce a method to apply and evaluate object recognition using virtual augmented images from 2D to 3D through GAN.

The purpose of this study was to analyze the conflicts in fishing villages, focusing on the Fishing Village New Deal 300 Project. In order to solve the research problem, the case analysis method was selected among qualitative research methods. Interviewees were selected as the village leaders and the MP(master planner) at the center of the project contest and promotion process. Of the leaders who were in charge of the project or in the villages selected for the project, three leaders who fully understood the purpose of this study were selected. The categorized results are as follows: First, difficulties in forming regional councils due to indifference of residents. Second, demanding excessive sacrifice of the leader. Third, the leader and the residents distrust of the local government. Fourth, the non-cooperation and intentional interference of the residents. Preventing and managing these conflicts is as follows: First, the regional arrangement of experts at the national level. Second, education for improving residents awareness. Third, structuralization of pre-learning and refueling systems. Forth, participation of residents in the decision-making process, Fifth, development and application of a practical road-map.

Korean cadastral system keeps graphical maps made by the plane table method from 1910's. The fact is that the graphical maps grafted on paper cover about 95% of the whole land (MOGAHA, 1999). The needs are arising to transform the graphical cadastre to a digital one in compliance with modem technologies. Korean government has already digitise the old maps until last year. A nation-wide land information system, Parcel-based Land Information System, was established upon the digitised map database. However, the accuracy of the digitised coordinates hardly meet the citizens' needs because it cannot exceed that of the paper maps. The definite solution will be surveying all the parcels again and making new digital maps. However, commencing a project for resurveying 34 million parcels will require enormous amount of time and manpower. The strategy should be dividing the country into county-wise or grid-wise pieces and surveying one piece by one piece. Municipal governments of counties, cities or urban districts will be the propelling bodies of the project but the costs will hardly be affordable at a time. For the purpose of resolving the financial problem, each municipality can split its own project into smaller pieces by year base. There is accordingly a great possibility to create inconsistency over the divided project areas caused by different techniques applied, different equipments used and/or mismatches between the project borders. It provides some merits at the same time. The people in project completion areas will be satisfied with the enhanced accuracy and feel safe in land transaction and, in turn, soundly improves overall nation-wide economic situation. Therefore, the main issue of the thesis shows how to make the cadastral re-survey project scalable. Guidelines for how to perform the projects will be derived from a experienced case.

본 연구에서는 대표적인 도시유출모형인 SWMM모형을 이용하여 기존의 침수예상지도가 고려하지 못했던 시간대별 침수예상지도를 작성하고 모형의 정확도 향상을 위해 연계모듈인 GeoSWMM을 개발하였다. GeosWMM은 GIS와 SWMM의 데이터 연계모듈로, 하수관망 GIS 네트워크 데이터로부터 SWMM 프로젝트 파일을 직접 생성할 수 있다. GeoSWMM을 이용하여 연구 사례지역인 서울특별시 서초구의 서초2동의 SWMM모형을 구축하였다. 실제 침수가 발생하였던 2010년 9월 21일의 시간당 실제 강우량 자료를 바탕으로 시나리오를 작성하여 홍수모의를 수행하였다. 홍수모의 결과 오후 2시를 기점으로 하수시스템의 통수능력 부족으로 인해 유출이 발생하는 것으로 나타났다. 이 결과를 바탕으로 시간대별 침수예상지도를 작성하였으며 2010년 침수흔적도를 기준으로 정확도 평가를 실시하였다. 평가 결과 침수예상지도가 침수흔적도와 약 66% 정도 일치하였다. 본 연구에서 개발한 GeoSWMM을 이용하면 SWMM의 입력 하수관망 데이터를 쉽게 생성할 수 있을 것이다. 또한 폭우 시 시간대별 침수예상지도 작성을 통해 도심지역에 대한 보다 효율적인 방재계획 수립이 가능할 것이다.

건설프로젝트의 성공은 프로젝트 관리자로서의 발주자의 참여가 중요하다. 그 이유는 일반적으로 프로젝트의 성공을 공기단축, 비용절감 등으로 측정하지만, 기존 성공을 측정하는 방법으로는 발주자의 역할을 고려하지 않고 있기 때문이다. 따라서 본 연구는 프로젝트 관리자로서 발주자를 위한 사업수행평가서를 개발하기 위해 통해 총 9개의 프로젝트 CSF와 27개의 sub-CSF를 도출하였다. 도출된 CSFs의 중요도를 평가하기 위해 AHP 기법을 활용하였으며, 기존 존재하던 PDRI 방법을 활용한 사업수행평가서를 개발하였다. 사업수행평가서를 활용하면 각 CSFs에 대한 초기 목표값을 설정하고 프로젝트 완료 후 평가 결과의 비교를 통해 프로젝트를 효과적으로 관리하고 평가할 수 있다. 평가결과를 실무적으로 활용하기 위한 솔루션 맵을 제시하고 활용 가능한 솔루션 툴을 제안한다. 추후 연구에는 실질적인 검증을 위해 다양한 프로젝트 사례를 추가할 뿐만 아니라 평가를 통해 현장에 적용 가능한 솔루션 툴을 지속적으로 개발해야한다.

Recently, As a part of NGIS project, cultural-assets digital map is produced by cultural properties administration and local autonomous entities. Cultural-assets unified GIS(Geographical Information System) is essential to cultural properties managers and other organizations which is executing land related business for appling it at planning stage. With explosive national land developments, it has been obligated to implement surface survey by the cultural properties protection Art(clause 2, Atr 74). In this paper, the author used the district of Sachon city and made 3D terrain model using digital map which is made of It5000 scale. moreover, the author improved to RDBMS(Relational Database Management System) structure and remodeled the existing DB design in detail. The author suggest to realize shape and kind of remains which have 3D information of accuracy and actualization from surface survey to excavation.

The objective of this research aims preliminary assessments of the proposed plans of offshore wind farm development based on the recently established national offshore wind map and suitability assessment system of offshore wind farm. Incheon Mueodo, Busan Dadaepo-Gadukdo, Sinangun Haeodo have been assessed considering geographic constraints such as water depth, offshore distance, national park, grid connection, and meteorological constraint such as wind power density and wind direction. According to the assessment, Mueodo plan has a weak point in grid connection and several geographic limitations are involved in Haeodo plan while Dadaepo-Gadukdo seems the most possible plan among the review cases. Because of limited assessment in this research, more detail and further consideration are necessary to make a decision of a feasibility project at proposed sites.
