Wooden cultural heritage is vulnerable to fire, flooding and other hazards. Therefore, an effective disaster prevention and mitigation strategy for them should include preventive measures in a full range of management. These were used to construct a disaster safety system for 508 wooden cultural heritage items by the Cultural Heritage Administration. According to the type of ownership and administration, national and public heritage is controlled by personal management or commissional management. Among them, it is arranged with the safety security institute for important cultural properties. In addition, they have problems of field management with no computerization about the management information for a disaster facility system. Therefore, this study aimed to develop a DB platform that can share information with many users who need to manage cultural heritage. Through a field survey, it is feasible to develop a disaster facility system to provide the information, such as the main data, quantity and location.

The purpose of this paper is to analyze the blind spot for public transportation by level of service(LOS) in public transportation supply service. For the purpose, we proposed indices of service coverage area, service frequency and hours of service and analysis method for them. Service coverage area analysis is to decide station location and network design for the maximum beneficiary area. Moreover, we can use the service frequency is for the maximum service frequency decision and hours of service is for the minimum operation hours. The results of this study are applied to the plan of minimum supply service, minimum service frequency and minimum operation hours for city and national public transportation plan.

Recently, the South and North Korea have collaborated in the economic cooperation. Success for the cooperation of the South and North Korea has supported the basic and fundamental GIS data building for geographic information (GI) and the land-use of the North Korea. This North Korea GIS project is also vital to facilitate rebuilding and reconnecting socio-economic infrastructures such as reconnecting road and railway networks between the South and North Korea. Thus, this paper emphasizes on the fundamental issues of GIS data building in North Korea area and suggests GI and data establishment methods of the North Korea regions which has not been achieved in GIS research activities in Korea. As the basic GI and data in the North Korea, topographical maps, satellite imageries, and thematic maps were collected and used for surveying of territorial areas of the North Korea. The database of those dataset were built by scanning, image processing, and classifying land-use types. In addition, this paper exacted vector data from the database and included the vector data into the database as other basic GI dataset that enable to analyze quantitative and qualitative territorial land use and development in the North Korea.

The transport mode choice problem is to determine which of the alternative transport modes connecting an origin and destination will be used by a traveler. Most of the research relating to transport mode choice have mainly been focused on modeling, properties, and applications of the model, but rarely were concerned with equilibrium among the modes. This paper proves the equilibrium among the modes by using a logit mode choice model, and then verifies it with the Korean Transport Database (KTDB). In order to obtain such an equilibrium, this paper also presents a solution algorithm based on the fixed point theorem. The algorithm was tested with an example and confirmed the equilibrium solution.

This study examined flow between regions based on the spatial structure of the territory and characterized the flow patterns by analyzing regional networks via transportation connectivity. To accomplish this, transportation connectivity of the entire nation was examined using 2010 national express bus OD data from the Korea Transport Database. After the initial analysis, 2010 car OD data describing networks in seven regions (125 cities and districts), Gangwon-do, Gyeongsangnam-do, Gyeongsangbuk-do, Jeollanam-do, Jeollabuk-do, Chungcheong-do and Seoul, were analyzed to identify transportation connectivity. The results revealed that Korea has strong triangular-belt-shaped transportation connectivity that connects among metropolitan areas in the Jeolla and Gyeongsang areas. Particular zones are set by regional characteristics and functional connectivity for each zone. The results of this study will be useful as a basic material to establish development strategies and customized regional policy development, as well as balanced development.

For efficient compatible system between medical clinics, the medical information has to be built on a standardized protocol such as a HL7 for text data and a DICOM for image data. But it is difficult to exchange information between medical clinics because the systems and softwares are different and also a structure of data and a type of code. Therefore we analyze a structure of DICOM file and design an integrated database for effective information sharing and exchange. The WISD system suggested in this paper separate the DICOM file transmitted by medical clinics to text data and image data and store it in the integrated DB(database) by standardized protocol respectively. It is very efficient that each medical clinic can search and exchange information by web browser using the suggested system. The WISD system can not only search and control of image data and patient information through integrated database and internet, but share medical information without extra charge like construction of new system.

인천 영종도는 물부족 위험평가 분석을 위해 Smart Water Grid연구단에서 선정한 데모플랜트로섬으로 고립된 지역이다. 영종도는 공촌정수장으로부터 상수도를 공급받고 있으며 관로 파손 등의 사고가 발생할 경우 외부 수자원으로부터 수도를 공급 받기 어려운 실정이다. 따라서 상수도 공급의 어려움이 발생할 경우 대체 수자원을 활용한 가용수량 산정과 이를 적용하기 위한 물수급평가 프로그램이 영종도에 적용 될 예정이다. 본 연구에서는 물수급평가를 위해 수문분석의 기초자료인 장래 예측 강수량을 제공하는 프로그램을 개발하였다. 장래 강수예측자료는 기상청 기상예보와 기후변화시나리오를 활용하였으며 Visual Studio2013을 통해 강수제공 프로그램을 개발하였고, 데이터의 저장과 DB서버 연동을 위해 Oracle 프로그램이 이용되었다. 기상청에서는 3일, 10일, 1달, 3달로 기간을 구분하여 강수확률 예보를 제공하고 있기 때문에 3개월 이내의 중 단기 예측은 기상청에서 제공되는 기상확률예보를 사용하였고, 3개월 이후의 장기 예측은 RCP 8.5시나리오에 의한 일단위 강수량이 활용될 수 있도록 하였다. 기상청 확률예보의 경우 퍼센트 확률을 정량적 수치로 환산하여 일단위 강수량으로 변환하여 제공하였다. 연구를 통해 개발된 강수제공 프로그램에서는 영종도 지역 내 행정구역 별 면적평균강수량이 제공되며, 기후변화시나리오에 의한 강수데이터 취득 시 고해상도(1km 격자단위)로 추출이 가능하도록 하였다. 사용자는 위 경도 좌표에 따라 일 및 월 단위의 강수데이터를 텍스트 파일 형태로 취득할 수 있고, 프로그램 화면 내 표출되는 그래프를 통해 현재대비 장래 강수량 변화를 확인할 수 있도록 하였다. 향후 Smart Water Grid 연구성과로 개발된 물부족위험평가프로그램과 연동하여 물수급평가, 가용수량 산정 등에 활용될 수 있을 것으로 기대된다.

최근 풍수해 현황 분석(국민안전처, 2016)에서는 2003년 이후 태풍 루사와 매미와 같은 대형태풍이 최근에 발생하지 않아 대부분 하천급류로 인한 인명피해가 대부분이라고 언급하였다. 최근 풍수해로 인한 피해가 발생하지는 않았지만 호우/태풍이 발생할 경우 인명보호와 불편해소를 최우선에 두고 각종 정책들을 선제적으로 추진하고 있어 홍수범람발생 예상지역에 대한 인명피해 분석은 반드시 필요하다고 판단된다. 최근들어 인명피해를 평가하는 기술은 피해자료로부터 비교적 간단히 분석되는 경험적 방법에서 2차원 동적 수리모형과 연계, 그리고 정밀한 인구, 건물 등의 자료를 활용하여 대피율, 사전경보 등 인명피해에 영향을 미치는 다양한 요소를 복합적으로 고려하고 개념적이고 기계적 방법으로 발전하는 추세이다. 우리나라의 경우 인명피해 평가와 관련한 연구사례가 거의 전무한 상태이고, 치수경제성분석에서 제시하는 침수면적에 기반한 간략한 방법만이 실무에서 활용되고 있다. 최근 국외에서 제시한 접근방법은 본 연구에서의 개발하고자 하는 목적과 방향에 부합하지 않다고 판단되며, 국내 실정을 고려할 때 주요 영향인자를 추가하고, 특히 노출인구, 인명 인벤토리의 해상도를 높이는 데 주안점을 두고자 한다. 홍수로 인한 인명피해 발생확률은 사후분석의 일환으로 침수흔적도를 통해 총 2개의 침수구간을 설정한 후 Census data를 활용한 위험인구(Population at Risk, PAR)를 산정한후, NDMS 인명피해 자료를 활용하여 침수구간별 인명피해 발생확률을 제시하였다. 여기서 제시한 침수구간의 경우 데이터의 축적정도에 따라 구간을 세밀화 할 수 있는데, 본 연구에서는 총 2개구간(0-1m, 1m 이상)으로 계략화 하여 제시하였다. 본 연구에서는 4개의 지자체의 인명피해 자료를 통해 인명피해 발생확률을 산정하였으며, 해당내용을 시범유역의 빈도별 침수구역도에 적용하여 인명피해 발생을 분석하였다. 해당 연구결과의 경우 인명피해에 대한 명확한 결과를 유추하는데에는 한계가 있지만, 인명피해에 기반한 해당지역의 장래피해규모를 예측하는 데에는 기초가 될 수 있을 것으로 판단된다.

This study suggests the development of a classification system for the Independent Movement Records of the Ministry of Patriots and Veterans Affairs based on the collection of Gonghun Digital Archive based on sources, subjects, and media types. First, the classification system by source is organized by hierarchy, and the records classified by source are classified into the second category based on the related keyword. Then, the records are classified into 17 media types. Finally, it is described in the citation order of "source-subject-media type." In addition, a meaningful collection using inductive methods based on the subject words is derived. Finally, Gonghun Digital Archive collections are categorized by media types, sources, and subjects so that users can easily find the records. The result of this study is a classification system to support records retrieval of an independent movement collection, and it will become a basis for expanding the accessibility of the user and the service of independent movement records.
