Crack in Pavements have been continually increased a by water penetration Therefore, the cracks can result in deterioration of the pavements that could be extremely dangerous fro road users. Creak sealing work performed in outdoor is very dangerous, costly and labor intensive. To slove these problems, automated crack sealing systems have been developed. it Would be needed that work information related to crack sealing must be gathered in an effort to used for existing or future crack sealing work. Furthermore, work information related to crack sealing could be utilized in analyzing work productivity and condition. The primary objective of this study is to propose a PDA and Web-based system for work information management of crack sealing which enables to effectively interchange work information between head office and fields, and to accurately collect work information. Finally, it is anticipated that the effective use of the developed PDA and web-based system would be able to effectively share work Information, measure productivity, estimate costs as well as plan future work schedule.

The importance of using construction data is increasing in accordance with the recent trend in the smart construction. However, construction project and maintenance information is distributed on the web, and the existing BIM(Building Information Modeling) information exchange and linking method using IFC(Industry Foundation Classes) cannot support connection with BIM data and web resources. This study aims to establish the BIM-based port facility data integration system using linked data(LD) technology in order to integrate BIM and heterogeneous data in the port maintenance domain. To this end, the port BIM-based ifcOWL and port facility maintenance ontology were designed, and LD was built for the BIM and maintenance information of Busan New Port 2-1 Pier3, a BIM pilot project. In addition, service prototypes such as search, statistics and SPARQL(SPARQL Protocol and RDF Query Language) endpoint functions were implemented using the issued LD. The LD-based information utilization system is expected to improve the reusability of information by converting the existing closed information system into an open system and BIM and maintenance data as a web resource in a standard format.

Rapid urbanization is being portrayed around the world au causing difficulty to manage public hygiene and maintain public order. Common problems often detected in urban areas including traffic congestion and the deterioration of the ecological environment are also being exacerbated. Despite all the effort being made by the government and local governments to manage urban facilities, urban residents are subjected to various levels of difficulty, due to the number of facilities to be managed exceeding the number of management personnel and the lack of an adequate management system. The aim of this study is to propose a management method using smart phones to improve the maintenance efficiency of urban facilities. First, the one-stop maintenance of urban facilities, including facilities information management, maintenance management and history management, is made possible by using smart phones to collect and transfer pictures and the locations of the urban facilities. Second, maintenance management is based on the location and picture information of the subject, not the location of the smart phones, which enables a prompt understanding of and actions to be taken for the facility. This method is especially effective as the smart phone application sends the facility status information directly to the maintenance personnel. Third, all of the information and figures relating to the facilities is managed using a database, resulting in the easy utilization of the history management and data. Fourth, all of the urban residents have access to this information via smart phone applications and, therefore, expanding the role of the facility maintenance personnel is made possible without any additional investment in infrastructure. Lastly, the location-based information enables the management of roads, trees and trails.

현재 정보검색분야에서는 검색도구로써 시소러스가 갖는 장점에도 불구하고 기존에 개발된 시소러스의 유지관리와 활용이 극히 제한적으로 이루어지고 있기 때문이다. 왜냐하면 정보의 급격한 증가로 인하여 전통적인 시소러스의 구조와 유지관리, 활용기법으로는 현대 정보의 홍수 현상에 적극적으로 대처하는데 한계에 직면하였기 때문이다. 이러한 한계점을 극복하기 위해 토픽맵의 구축알고리즘이 절대적으로 필요하였다. 이에 따라 본 연구에서는 토픽맵의 기본요소인 토픽과 대상물, 연관관계, 토픽타입 등을 이용한 시소러스 구조화 알고리즘을 제안하였다. 특히 토픽맵의 기본 요소가운데 대상물(occurrence)은 시소러스의 검색효율가운데 정도율의 확보를 가능하게 하며, 시소러스의 구축에 필요한 지식베이스의 역할을 수행하는 주요한 기법임을 확인하였다.

Facility Management is the longest in the building of life cycle. Because it occupies more than 80% of cost, the phase of Facility Management has to be managed and has to be perceived as important as design and construction phase. The method to manage building more efficiently is the introduction of Facility Management System used by CAD and database. But information Requirement is now input by hand in the most Facility Management System. This study aims to analyze the example of applying BIM in the Korea or abroad and the errors of this were deducted by many phase. Lastly, the possible solution is suggested in order to be used in the Facility Management System. This study's benchmarking is COBIE which is developed by the COE(Corps of Engineers) and now popular in the world. The suggestion in this study is the method that I have already mentioned is helpful for a designer to do modeling when a designer uses BIM S/W(software). To be more specific, the method plays a side role in helping data input considering the phase of Facility Management.

정보통신의 발달과 함께 인터넷의 보급으로 이제 가정에서 멀티미디어 서비스의 개념은 더이상 생소하지 않다. 오히려, 가정에서 고화질 및 고속으로 주문형 비디오, 텔레뱅킹, 홈쇼핑, 원격 교육과 같은 멀티미디어 서비스를 제공받기를 원하고 있고, 이와 더불어 가전 기기들 역시 점차 디지털화되고 통신 기능을 탑재하게 되는 정보가전으로 발전하고 있다. 따라서 이들 정보가전들간의 고속의 통신 기술을 일컫는 흠 네트워킹(Home Networking)을 위한 여러 기술들이 제안, 연구 개발 중에 있다. 반면, 이러한 홈 네트워킹을 위한 관리 측면에 있어서는 다루어지고 있지 않다. 홈 네트워킹을 편리하게 사용하는 것도 중요하지만 네트워크의 성능을 최대화하기 위한 홈 네트워크 유지 관리 측면도 소홀히 해서는 안 된다. 왜냐하면, 흠 네트워킹의 사용자 및 관리자는 일반 가입자들이기 때문이다. 본고에서는 홈 네트워킹의 관리자가 일반 가입자라는 특성을 감안하여 가정에서 네트워크를 구축하였을 때 이를 유지 관리하기 위한 여러 가지 사항들을 분석 제시하여 IEEE 1394 초고속 직렬 버스상에서 홈 네트워크를 유지 관리하기 위한 관리 시스템을 설계해 보았다.

Git의 커밋 메시지는 프로젝트가 진행되면서 발생하는 각종 이슈 및 코드의 변경이력을 저장하고 관리하고 있기 때문에 소프트웨어 유지관리와 프로젝트의 생명주기와 밀접한 연관성을 갖고 있다. 이러한 Git의 커밋 메시지에 대한 정확한 분석 결과는 소프트웨어 개발 및 유지관리 활동 시, 시간과 비용의 효율적인 관리에 많은 영향을 끼치고 있다. 이에 대한 기존 연구로 Git에서 발생하는 커밋 메시지를 소프트웨어 유지관리의 세 가지 형태로 분류하고 매핑하여 정확한 분석을 시도하려는 연구가 진행되었으나, 최대 87%의 정확도를 제시한 연구 결과가 있었다. 이러한 연구들은 정확도가 낮아 실제 프로젝트의 개발 및 유지관리에 적용하기에는 위험성과 어려움이 있는 현실이다. 본 논문에서는 커밋 메시지 분류에 대한 선행 연구 조사를 통해 각 연구들의 프로세스와 특징을 추출하였고, 이를 이용한 분류 정확도를 높일 수 있는 커밋 복합 분류 모델에 대해 제안한다.
