Metropolitan rapid transit system plays an essential role in the public transportation system of any large city, and its managing agency is usually charged with the responsibility of storing and managing the design drawings of the system. The drawings are important and historically valuable documents that must be kept permanently because they contain comprehensive data that is used to manage and maintain the system. However, no study has been performed in Korea on how well agencies are preserving and managing these records. Seoul Metropolitan Rapid Transit Corporation(SMRT) is the managing agency established by the city of Seoul to operate subway lines 5, 6, 7, and 8 more efficiently to serve its citizens. By the Act on Records Management in Public Institutions(ARMPI), SMRT should establish a records center to manage its records. Furthermore, all drawings produced by SMRT and other third party entities should be in compliance with the Act. However, SMRT, as a form of local public corporation, can establish a records center by its own way. Accordingly, the National Archives & Records Service(NARS) has very little control over SMRT. Therefore, the purpose of this study is to research and analyze the present state of storage and management of the drawings of metropolitan rapid transit in SMRT and is to find a desirable method of preservation and management for drawings of metropolitan rapid transit. In the process of the study, it was found that a records center is being considered to manage only general official documents and not to manage the drawings as required by ARMPI. SMRT does not have a records center, and the environment of management on the drawings is very poor. Although there is a plan to develop a new management system for the drawings, it will be non-compliant of ARMPI. What's happening at SMRT does not reflect the state of all other cities' metropolitan rapid transit records management systems, but the state of creation of records center of local public corporation is the almost same state as SMRT. There should be continuous education and many studies conducted in order to manage the drawings of metropolitan rapid transit efficiently by records management system. This study proposes a records center based on both professional records centers and union records centers. Although metropolitan rapid transit is constructed and managed by each local public corporation, the overall characteristics and processes of metropolitan rapid transit projects are similar in nature. In consideration of huge quantity, complexity and specialty of drawings produced and used during construction and operation of metropolitan rapid transit, and overlap of each local public corporation's effort and cost of the storage and management of the drawings, they need to be managed in a professional and united way. As an example of professional records center, there is the National Personnel Records Center(NPRC) in St. Louis, Missouri. NPRC is one of the National Archives and Records Administration's largest operations and a central repository of personnel-related records on former and present federal employees and the military. It provides extensive information to government agencies, military veterans, former federal employees, family members, as well as researchers and historians. As an example of union records center, there is the Chinese Union Dangansil. It was established by several institutions and organizations, so united management of records can be performed and human efforts and facilities can be saved. We should establish a professional and united records center which manages drawings of metropolitan rapid transit and provides service to researchers and the public as well as members of the related institutions. This study can be an impetus to improve interest on management of not only drawings of metropolitan rapid transit but also drawings of various public facilities.

사용연수가 30년 이상 된 노후 시설물은 향후 10년 사이 3배 이상 급증될 것으로 조사되고 있다. 또한, 2017년 행정안전부 "내진설계기준 공통적용"개정으로 도로시설물의 내진성능 확보유무가 검토되어야 하며, 이는 기존 설계기준을 통해 내진보강 되었거나, 내진설계가 된 시설물을 포함한 모든 기존 도로시설물을 대상으로 내진성능 확보유무가 재평가 되어야 함을 의미한다. 이렇듯 대량의 시설물에 대한 내진성능관리를 위해서는 빠른 시간 내에 경제적이고 신뢰성 있는 결과를 제공할 수 있는 의사결정 지원기술이 필요하다. 하지만, 우리나라에서 사용되고 있는 지수평가방법은 결정론적인 방법으로서, 개별시설물의 내진성능을 정성적인 지수 값으로 산정하고 지수 값의 크기에 따라 내진보강 우선순위만을 결정하고 있어 합리적인 내진성능관리를 위한 다양한 의사결정을 지원하기 어려운 실정이다. 이러한 단점을 극복하고 내진성능관리 의사결정에 필요한 시설물의 직접손실비용, 사회·경제적 간접손실비용, 재원투입효과 등의 정보를 제공할 수 있는 지진위험도평가 방법으로 전환이 필요하다.

Agricultural drought is a natural phenomenon that is not easy to observe and predict and is difficult to quantify. In South Korea, the amount of agricultural water used is large and the types of use are varied, so even if an agricultural drought occurs due to insufficient precipitation, the drought actually felt in the irrigated area is it can be temporally and spatially different. In order to interpret the general drought in the past, drought disasters were evaluated using single indicators such as drought damage area, precipitation shortage status, and drought index, and a comprehensive drought management system is needed through drought diagnosis survey. Therefore, we intend to conduct research on agricultural drought assessment and diagnosis using re-evaluation of agricultural facilities and irrigation water supply network due to changes in various conditions such as climate change, irrigation canal network, and evaluation of water supply capacity of agricultural facilities. In this study, agricultural drought diagnosis was conducted on two agricultural reservoirs located in Sangju, Gyeongsangbuk-do, with structural or non-structural evaluations to increase spatiotemporal water supply and efficiency in terms of water shortages. The results of the agricultural drought diagnosis evaluation can be used to identify irrigated areas and canal network vulnerable to drought and to prioritize drought response.

This study aims to analyze the characteristics of the management situation of the Korea Railroad Corporation(KORAIL) through the management innovation process of the KORAIL and to suggest its implications for military application. Despite stable demand, the railway passenger industry had the limitation of not being able to abolish deficit routes due to public service obligations. In addition, the launch of the Suseo High-Speed Line has introduced a competitive system, posing a threat to corporate management. KORAIL wanted to overcome this crisis by innovating its management through the utilization of big data, improvement of the freight business, decentralization of demand, the introduction of tourism railroads, and development of station influence areas. By utilizing big data, KORAIL was able to optimize the railway fare system while reducing fixed costs spent on railway maintenance. It also drastically reduced the station of cargo and created a base station to pursue economies of scale. On the other hand, the existing exclusive station system was abolished to solve the chronic saturation of the downtown area, and the railway demand was moved to Gwangmyeong Station and Suwon Station to optimize the passenger supply. In particular, it developed a new business model called the tourism railway by developing the mountain Byeokjin Line, which was a chronic deficit line, and sought to improve liquidity through the development of the station influence area. Such a process of innovation at KORAIL suggests an appropriate direction in seeking ways to innovate the military medical institutions. First of all, the necessity of improving organizational immersion through the development of a personnel structure suitable for the compulsory organization, while expanding the facilities of the division and corps, and reducing the time required for medical treatment and waiting through the establishment of a data-based medical system was suggested. Next, it was also discussed to integrate the National Health Medical College, which received accreditation as a medical facility through the designation of advanced general hospitals and is ultimately under discussion with the Medical Institution. Through this, we hope that the military medical institutions, which are facing various challenges, will overcome existing limitations and be re-lighted as innovative institution that provides comprehensive public health services.

Purpose In this study, the relationships among environmental information exchange with suppliers(EIES), green collaboration with suppliers, green learning by environmental information, the adoption of green supply-chain management techniques(AGSMT) (i.e., the green purchasing, product design and production, and the recovery of extra facilities and inventories), environmental performance, and the organizational performance of a firm were empirically investigated. Design/methodology/approach Data for this study were drawn from a survey of the current status of EIES levels and AGSMT usage observed in Korean manufacturing firms. In total, 500 organizations were randomly selected from a population of about 1,000 firms that are listed on the Korean stock market. In order to collect empirical data, this research administered questionnaires with the sample firms. Only chief production executives were selected as respondents. A questionnaire with a cover letter was mailed to each respondent. The survey was conducted during a 3-month period between March 2015 and June 2015. Finally, 78 valid data of the sample firms were collected. Findings The results of this study showed that EIES positively affects the green corporation and learning. According to the results, it was observed that both green corporation and green learning have a positive impact on the levels of AGSMT(i.e., the green purchasing, product design and production). It was also demonstrated that AGSMT has a direct positive impact on environmental performance. In examining the effects of environmental performance on the organizational performance of a firm, significant impact was found.

Purpose - This research primarily assesses interactive quality in the service encounters of Ethiopian Telecom from the customer and contact personnel perspectives. Research design, data, and methodology - After reviewing the literature on service encounters and interactive quality, two separate questionnaires and structured personal interviews were conducted to collect the opinions of 400 customers and 100 employees of Ethiopian Telecom. The researchers used convenience sampling; the responses, measured on a five-point Likert-type scale, were analyzed through chi-square tests conducted on SPSS 17.0. Results - Regarding the outcome expected by customers, encounter effectiveness is very low. Regarding accessibility and materiality, the corporation's personnel are freely accessible, relatively well-dressed, and have access to sophisticated office equipment and physical facilities. Finally, with regard to agent satisfaction, the telecom's contact employees are shown to gain little professional satisfaction from service encounters. Conclusion - The study clearly presents the areas in which interactive quality strongly affects both telecom customers and employees; this will help the corporation take corrective action. This is of utmost contemporary importance for both practitioners and researchers.

산업의 성장으로 가스사용량이 증가함에 따라 가스설비, 화학플랜트 등 시설 또한 점차로 증가하고 있으나, 가스에 대한 안전관리는 여전히 미흡한 실정이다. 공장과 가정에서 많이 사용되고 있는 메탄은 천연가스의 주성분으로 가연성이면서 폭발성가스이어서 그에 대한 안전관리도 매우 중요하다. 그 한 가지 방안으로 $3.2\;{\mu}m$ 중적외선 영역의 LED 및 PD를 이용하여 메탄가스누출검지시스템을 개발하고자 한다. 이 파장대역의 센서로 레이저를 이용할 경우 고열이 발생하여 초저온 냉각장치가 필요하나 LED는 상온에서 동작함으로 냉각장치가 필요 없다. 그래서 초소형이나 휴대용으로 구현이 가능하다. $3.2\;{\mu}m$ 부근의 파장대역은 $1.67\;{\mu}m$에 비하여 메탄흡수강도가 강하여서 극미량의 가스탐지가 가능하고 응답성 또한 빠르다. 본 연구에서는 이를 상용화하여 매설 및 노출배관 등 가스설비의 가스누출을 보다 정확하고 신속히 검지함으로써 사고를 미연에 방지하고 그 피해를 최소화하고자 한다.
