최근 정부(정보통신부)는 사이버 아파트를 포함하여 초고속 정보통신망을 2005년까지 구축하여 각 가정당 10Mbps의 고속 정보통신 서비스를 실현한다는 계획을 발표하고, 초고속 정보통신을 활성화하므로 정보통신 선진국 진입을 위하여 "초고속 정보통신 건물 인증제도"를 발표, 현재 시행하고 있다. (1999.7 제정발표) 그러나 시행 과정에서 아파트 중앙 관리실에 있는 MDF 이후의 광케이블과 기타 공사는 건설회사에서 시공하고 중앙 관리실 MDF 이전의 광케이블 공사와 중앙관리실 LAN시설 등의 공사는 통신 전문업체로 하여금, 입주자 별도 부담금으로 시공하고 있다. (컨소시엄 구성) 최근 아파트 분양열기 고조로 건설회사 마다 "초고속 정보통신 아파트"인증 1등급이라고 선전 및 분양광고 중인데 실제는 "1등급"이 아니고 "2등급" 또는 "3등급"인 경우가 있어, 정부가 목표하는 각 가정당 10Mbps, 개인당 2Mbps 고속정보통신 서비스는 실현성에 문제점이 있다. 정부의 인증심사 기준에 중앙관리실 장비 등에 대한 것은 심사기준에 누락되어 있고 또 사생활 정보보호를 위한 대응기술, 시스템 준비 정도까지 포함하여 종합적으로 평가한 뒤 인증을 부여하여야 한다는 것이 본인의 연구 초점이다. 사이버 아파트란 광통신을 주축으로 영상과 음성, 데이터를 자유자재로 전송 처리하는 초고속정보통신망을 이용하는 것으로 LAN 장비를 이용하여 각 세대간 통신은 물론 누구나 인터넷을 사용할 수 있는 기능이 있는 설계된 아파트를 말한다. 사이버 아파트의 네트워크에는 금융, 홈쇼핑, 예약, 지역정보, 관공서, 의료서비스, 레저 생활정보 등 차별화된 콘텐츠 확보가 필요하다. 본 연구의 핵심은 사이버 아파트의 현 실태와 문제점, 정부의 인증심사 기준의 미비점과 문제점, 사이버 아파트의 기능, 구성요소, 시스템 구축, 서버활용도, 장비들에 관한 것과 그리고 정부의 사이버 아파트 육성정책, 정보보호 대책과 관련업체들의 동향 등을 연구하여 요약 정리하였다.

2018년 환경부에 따르면, 영산강은 5대강 중 수질이 가장 열악하고 유량이 적어 수질개선이 어려우며 상류에 다목적댐이 없기 때문에 하천유지용수 확보가 어렵다고 보고 하였고, 섬진강은 생태 및 염해 피해 문제와 섬진강 유역의 수자원의 약 81%는 영산강과 동진강 및 남해로 공급되고 있어 이에 따른 용수 배분에 대한 문제가 지속적으로 발생하고 있음을 보고했다. 이와 같은 수량문제는 두 개의 유역환경에 영향을 미치고 유역에 위치한 도시지역들의 갈등 심화 및 두 개의 수계에 대한 미래 수자원 계획과 관리에 있어서 어려움을 가중시킬 것으로 예상되어 영산강과 섬진강수계에 대한 물수지 분석을 통한 물수급 관리가 필요하다. 이에 본 연구에서는 영산강유역 ($3,371.4km^2$)과 섬진강유역($4,896.5km^2$)을 대상으로 SWAT(Soil and Water Assessment Tool)모형을 이용하여 주암댐 도수에 따른 영산강유역과 섬진강유역의 수문 영향을 평가하고자 하였다. 두 개의 유역의 물수지 분석을 위해 각 유역을 표준단위 유역으로 구분 하였고, 기상자료와 섬진강 내 다목적댐 2개(섬진강댐, 주암댐)과 영산강 내 다기능 보 2개(승촌보, 죽산보)의 운영 자료와 국가 수자원관리 종합 정보 시스템(WAMIS)에서 관측 및 관리하고 있는 수문, 기상 자료와 도수의 영향을 파악하기 위해 주암댐에서 방류하는 실제 도수유량 자료를 수집하였다. SWAT 모형의 신뢰성 있는 수문과 수질 보정을 위해 영산강과 섬진강의 소유역 내 위치하는 다목적 댐 2개와 다기능 보 2개의 실측 방류량을 이용하여 댐과 보 운영모의를 하였으며, 댐 운영 자료와 수질 자료를 이용하여 모형의 검정 및 보정(2005~2017)을 실시하였다. 주암댐에서 도수하는 것을 모의하기 위해 영산강에서는 SWAT 모형 내에 있는 Inlet 기능을 이용하여 외부 유량을 유역 내 적용할 수 있도록 유역을 재구축 하여 실제 도수유량자료를 적용하였고 섬진강에서는 매개변수를 이용하여 실제 도수유량 만큼을 제하고 방류 할 수 있도록 설정하여 모의기간(2005~2017)에 대해 주암댐도수에 따른 영산강 유역과 섬진강 유역의 수문 영향 평가를 실시하였다.

Smart City is urban development for complex problem solving that provides convenience and safety for citizens, and it is a blueprint for future cities. In 2008, the Korean government defined the construction, management, and government support of U-Cities in the legislation, Act on the Construction, Etc. of Ubiquitous Cities (Ubiquitous City Act), which included definitions of terms used in the act. In addition, the Minister of Land, Infrastructure and Transport has established a "ubiquitous city master plan" considering this legislation. The concept of U-Cities is complex, due to the mix of informatization and urban planning. Because of this complexity, the foundation of relevant regulations is inadequate, which is impeding the establishment and implementation of practical plans. Smart City intelligent service facilities are not easy to define and classify, because technology is rapidly changing and includes various devices for gathering and expressing information. The purpose of this study is to complement the legal definition of the intelligent service facility, which is necessary for integrated management and operation. The related laws and regulations on U-City were analyzed using text-mining techniques to identify insufficient legal definitions of intelligent service facilities. Using data gathered from interviews with officials responsible for constructing U-Cities, this study identified problems generated by implementing intelligent service facilities at the field level. This strategy should contribute to improved efficiency management, the foundation for building integrated utilization between departments. Efficiencies include providing a clear concept for establishing five-year renewable plans for U-Cities.

This study was conducted to identify the effects of interpersonal communication between health care providers after receiving supplementary education. The participants of this study were 433 health care providers who work at 29 general hospitals in Gwangju Metropolitan City and Jeollanamdo Province. Data were collected from June 8 to June 25, 2018 and evaluated by t-tests, dispersion analysis, correlation analysis and stepwise regression. The results were produced by investigating interpersonal communications according to socio-demographic and health-related characteristics including age, education level, bed size of the hospital at which the participant worked, job satisfaction, hospital location, personal health status, experience with health care management and experience with depression. There were significant differences in communication observed according to supplemental education awareness regarding age, bed size of hospital, occupation, wage, type of medical institution of employment, job satisfaction, work location, health status, health care education experience and chronic disease. There were positive correlations between supplemental education awareness in health workers and their interpersonal communication. The factors that had positive effects on interpersonal communication were level of education and health-related education experience, while age, hospital bed size and job dissatisfaction had negative effects. Finally, support environment, learning transfer and results were identified as sub-factors of supplemental education. Based on the results above, it was proposed that educational training to enhance results, provide a supportive environment and foster learning transfer be developed to increase communication between health workers and provide a safe health service for patients.

An integrated sediment management approach that includes the recovery of the amount of declined sediment supply is effective as a fundamental solution to coastal erosion. During planning, it is essential to analyze the transfer mechanism of the sediments generated from estuaries (the junction between a river and sea) to assess the amount and rate of sediment discharge (from the river to sea) supplied back to the coast. Although numerical models that interpret the tidal sand bar flushing process during flooding have been studied, thus far, there has been no study focusing on the formation and development processes of tidal sand bars. Therefore, this study aims to construct wave deformation, flow regime calculation, and topographic change analysis models to assess the amount of recovered sediment discharge and reproduce the tidal sand bar formation process through numerical analysis for integrated littoral drift management. The tidal sand bar formation process was simulated, and the wave energy and duration of action concepts were implemented to predict the long-term littoral movement. The river flux and wave conditions during winter when tidal sand bars dominantly develop were considered as the external force conditions required for calculation. The initial condition of the topographic data directly after the Maeupcheon tidal sand bar flushing during flooding was set as the initial topography. Consequently, the tidal sand bar formation and development due to nearshore currents dependent on the incident wave direction were reproduced. Approximately 66 h after the initial topography, a sand bar formation was observed at the Maengbang estuary.

Archival Objects are defined as objects having historical, aesthetic, and artistic value as well as archival value created and used with a particular purpose in business process. Increasingly, many countries including Canada, Australia, China are recognized the importance of Archival Objects and designated them as national records. In Korea, Archival Objects are involved in national records through '2006 Plan for the Archives and Records Management Reform'. So National Archives and Records Service provided a foothold for comprehensive plan of national records management including Archival Objects. And also, by revising Records and Archives Management Act in 2007, National Archives and Records Service declared aggressive will to management Archival Objects. Until now, Objects held in public institution were easy to be damaged because definition or scope of Archival Objects was ambiguous and management system for material character wasn't exist. Even though the revised Records and Archives Management Act suggest definition and declare the responsibility of management, management system focused on various shape and material of objects need to be established. So this study has defined Archival Objects shortly and carried out a research 5 institutions on the actual management condition. By researching the result of institution survey, Records and Archives Management Act and actual Records Management System, we could find some problems. In solving these problems, We provide objects management process in the order capture ${\rightarrow}$ register ${\rightarrow}$ description ${\rightarrow}$ preservation ${\rightarrow}$ use${\rightarrow}$disposition. In addition, close cooperation between records center and museum of institution should be established for the unitive management at national level. This study has significance in introducing a base to manage Archival Objects systematically. By studying more, we hope to advance in management of valuable Archival Objects.

The significant of continuous welded rail (CWR) management is growing because KORAIL has the plan to convert the whole of conventional railway lines into CWRs through continuous activities since constructed the CWR track with 1.8km in Gyeongbu line in 1966. The CWR recently is needed a efficient management method because it is difficult to manage the CWR by the poor of technic and equipment, limited maintain labor force and shorted the maintain work time of CWR caused by industrialization, greenhouse effect and global warming In this point, The 70ton Tenser's which is using in the rail site has been analysised with no extra tenser's capacity in case of the under low temperature and exceed the length of 1km as a result of reviewing the CWR-related rules and standards, a series of records of safety accidents, operation obstacles, and the situation of broken rails published by KORAIL, existing rail temperature measurements, and CWR researches. Therefore avoid the excessive plan of the first set-up section, choice the proper time in the normal temperature that is possible to weld the rail, turning the difference of rail temperature and Installation temperature down is desirable.

Recently, mainly in downtown, there have been frequent safety incidents in underground space like ground subsidence and land sinking. Out of diverse coping measures, the government is carrying forward the establishment of underground space integrated map. As a core element of the underground space integrated map, the 3D geotechnical information is used as major data of underground space impact assessment obliged in accordance with the "Special Act on the Safety Control of Underground Space Safety". The construction method of 3D geotechnical information is drawn when establishing the basic establishment plan of underground space integrated map, and the continuous construction is performed by the Integrated DB Center of National Geotechnical Information. However, it is necessary to draw concrete measures with accuracy, efficiency, and utilization. This study drew the construction plan considering the accuracy, utilization, and efficiency of 3D geotechnical information for the support of underground space safety. For this, accuracy between elevation and underground level is compared using MVS and MakeJiban which are software to construct boring information with geotechnical information in geotechnical information portal system. In the results of general analysis, the milepost-based construction of whole strata in a lump would be the most suitable in the aspect of accuracy, utilization, and efficiency. Based on the results of this study, Plan to construct 3D geotechnical information will be pursued.

Heathcote (1998) identified a systematic, seven-step approach to general watershed planning and management. It consists of 1) understanding watershed components and processes, 2) identifying and ranking problems to be solved, 3) setting clear and specific goals, 4) developing a list of management options, 5) eliminating infeasible options 6) testing the effectiveness of remaining feasible options, and 7) developing the final options. In this study the first five steps of that process were applied to the Anyangcheon watershed in Korea, which experiences streamflow depletion, frequent flood damages, and poor water quality typical of highly urbanized watersheds. This study employed four indices: Potential Flood Damage(PFD), Potential Streamflow Depletion(PSD), Potential Water Quality Deterioration(PWQD) and Watershed Evaluation Index(WEI) to identify and quantify problems within the watershed. WEI is the integration index of the others. Composite programming which is a method of multi-criteria decision making is applied for the calculation of PSD, PWQD and WEI (Step 2). The primary goal of the study is to secure instreamflow in the Anyangcheon during dry seasons. The second management goals of flood damage mitigation and water quality enhancement are also set (Step 3). Management options include not only structural measures that can alter the existing conditions, but also nonstructural measures that rely on changes in human behavior or management practices (Step 4). Certain management options which are not technically, economically, and environmentally feasible, are eliminated (Step S). Therefore, this study addresses a Pre-feasibility study, which established a master plan using Steps 1 through 5.
