통신망의 물리적 기반이 광케이블로 대치됨에 따라 광케이블 선로의 품질유지 및 체계적인 관리에 대한 요구도 점차 증대되고 있다. 한국통신은 광케이블 선로의 유지보수 체계를 확립하고 자동화 하기 위하여 광선로 운용 감시 시스템(FLOMS:Fiber Line Operation & Monitor System, 이하 FLOMS라 한다.)을 개발하였다. FLOMS는 광케이블 시설에 대한 체계적인 관리 및 광케이블 선로 특성시험 자동호를 통한 선로의 이상 유무를 체크하고 보고할 수 있다. 광케이블 유지보수 요원은 FLOMS 시스템을 이용하여, 운용센터에서 관리대상 전화국의 광케이블 선로들을 원격시험 할 수 있으며 기존의 광전송장치 운용관리 시스템과 연동함으로써 전송분야 운용관리의 통합관리가 가능하게 되었다. 이 시스템을 적용함으로써 광케이블 선로 고장위치의 신속한 파악에 의한 공장시간 단축, 광케이블 선로 특성의 주기적인 측정에 의한 예방보전, 광케이블 심선 정보의 전산화 관리에 의한 업무효율의 향상을 이룩하였다.

Purpose: This study was conducted to develop a web-based business management system to ensure the efficient operation and transparent management of government-subsidized agricultural machinery rental businesses. Methods: An MS_SQL2000 database management system (DBMS) solution was utilized in the system for high system compatibility and integrated management. This system was targeted to be compatible with Internet Explorer 6.0 or later and to ensure security and seamless web operations. The system administrator is able to manage a fleet of agricultural machinery, including various inventory codes, release and return, fleet registry, and business performance. Users (farmers) may search the database of rental machinery and reserve them. Results: With respect to rental reservations, the system administrator can manage the fleet by setting the rental status to Approved, Released, or Returned. Through the web, the administrator can also create a database that includes machinery specifications, features, and rental rates. In addition, business performance data can be analyzed using a diverse array of tools to streamline the rental business. Without having to go to the rental office, users can save time and money by searching for and renting agricultural machinery through the information available on the website, including availability, specifications, and rental fees. After deploying the system, the time required to analyze monthly performance and create reports was dramatically reduced from 20 days per person to one day per person. Conclusions: Since 2014, AMRB has been installed and is operating in agricultural machinery rental businesses in 31 cities and counties in South Korea. This study recommends continued expansion and dissemination of AMRB for the systematic and efficient management of agricultural machinery rental businesses.

The studies on semiconductor industrial accident in korea have been focused on the frequencies of each type of safety management employee, characteristics, cause and unsafe conditions, acts and so on. Those attributes of semiconductor industrial accidents were usually analyzed independently, so that it was hard to provides a wel-developed process and systematic guidelines for efficient safety management. Therefore, there were a few studies based on comprehensive survey in terms of the shape type of safe management. The questionnaire survey carried out for the 284 workers who were responsible for safety management in center with cooperation companies in semiconductor industry factor analysis showed that there were three factors of safety management. First, investment and operation and management for accident prevention, Second, unsafe act and condition, safety management Third, general human error and behavior. The industries of respondents were correlative with three groups. Three groups showed statistically significant differences on the number of cases. Actually, the group with the larger investment and the more unsafe cause, human error of accidents prevention had a smaller causes of accident cases.

A production management system is developed to enhance both the information and productivity of ship and offshore plant deckhouse floor outfitting. The functions of the production management system for the deckhouse floor outfitting were reviewed based on a literature survey of several production management systems with respect to the ship building and architecture fields. This study investigated numerous daily production reports and their application to actual work places to utilize the system development. The developed scanned drawing-based production management (SDPM) system minimizes any loss and/or distortion of work information between the workshop and management office when applying a scanned production drawing to the daily report. The SDPM system increases the data objectivity, as well as intuitiveness of the information generation by adopting an efficient user interface, which makes it possible to perform image annotations on the scanned drawing for the daily production report while simultaneously interacting with the production management database. Applying the system operation to actual deckhouse floor covering work verified that it was feasible to use the SDPM system for production management in the ship outfitting work process.

본 연구는 유역의 가뭄 예ㆍ경보 기준을 사용한 저수지 운영과 저수지의 운영률을 수행한 결과를 비교하여, 보다 효율적인 저수지 운영방안을 검토하였다. 그 결과 가뭄 예ㆍ경보 시스템과 방류계수를 사용한 저수지 운영이 기존의 저수지 운영률을 사용한 저수지 운영에 비하여 신뢰도와 연평균 저류량이 향상됨을 확인할 수 있었다. 시범유역으로 선정된 금강유역의 용담댐에서 저수지 운영시 사용할 방류계수로는 가뭄주의일 때 0.95, 가뭄경보일 때 0.9, 가뭄비상일 때 0.85의 값이 가장 효율적인 것으로 검토되었다. 가뭄 예$\cdot$경보를 사용한 저수지 운영은 가뭄시 수자원의 효율적인 이용을 가능하게 하며, 국가 수자원 관리에 크게 이바지할 것으로 판단된다.

An air traffic control organization will require knowledge management to keep competitive advantage. A traffic controllers are forced to share their tacit as well as explicit knowledge among their organization to get aircraft's safety and efficient operation. The purpose of this study is to examine which factors influence the air traffic controllers' intention of sharing knowledge for the case of Civil Aviation Safety Authority, Ministry of Construction and Transportation. An ANOVA analysis shows that a difference exists between ages in terms of open mindedness towards sharing knowledge, the search for new knowledge and the recognition of the importance of sharing knowledge.
