In this paper, the problem of subway platform is analyzed and the alternative as a screen door is suggested. This paper aims to improve the facility law in subway platform. Because facility law related to platform is absent, the study scope is limited to detail design that is matched to rules. Field survey is performed to 300 persons that are 150 men and 150 women in Shingil station in which the screen door is established. Also the persons are used the screen door at least 3 times. It makes the field survey credible. The study is proceeded as follows ; First, the law related to platform, the problem of platform, and the plan and status of screen door are analyzed. Second, the definition, and composition of screen door are examined. Then, kinds of screen door is analyzed and the advantage and disadvantage of each kind of screen door are compared. Third, the necessity of establishing the screen door is examined through field survey and error range of stop position is investigated. Through this flow, final results is abstracted. Direction of facility related to subway platform, applied objective and range are suggested based on this study. This study focuses the stability of platform, pleasantness, and energy saving and suggests facility improvement direction through introducing the screen door and further study.

In this study, a smart isolation platform has been developed for control of microvibration of high-technology facilities, such as semi-conductor plants and TFT-LCD plants. Previously, microvibration control performance of a smart base isolation system has been investigated. This study compared microvibration control performance of a smart isolation platform with that of conventional base isolation and fixed base. For this purpose, train-induced ground acceleration is used for time history analysis. An MR damper was used to compose a smart isolation platform. A fuzzy logic controller was used as a control algorithm and it was optimized by a multi-objective genetic algorithm. Numerical analysis shows that a smart isolation platform can effectively control microvibration of a high-technology facility subjected to train-induced excitation compared with other models.

Purpose This study investigates the impact of organizational characteristics on organizational performance through case studies of smart factory implementation in the context of Korean small and medium Enterprises (SMEs). To achieve this goal, this study adopts the smart factory index of KOSMO (Korea Smart Manufacturing Office) established by Korean Ministry of SMEs and Startups. We visited 3 firms implemented smart factory projects. This study presents the results of field study in detail with evaluation criteria on how organizational competences like AI technology adoption and facility automation can be exploited to positively influence organizational performance through smart factory implementation. Design/methodology/approach There are not so many results of empirical studies related to smart factories in Korea. This is because organizational support and user involvement are required for facility AI platform service beyond factory automation after the start of the 4th Industrial Revolution. Korean government's KOSMO (Korean Smart Manufacturing Office) has developed and proposed a level measurement index for smart factory implementation. This study conducts case studies based on the level measurement method proposed by KOSMO in the process of conducting case studies of three companies belonging to the root and mechanic industries in Korea. Findings The findings indicate that organizational competences, such as facility AI platform adoption and user involvement, are antecedents to influence smart factory implementation, while smart factory implementation has significant relationship with organizational performance. This study provides a better understanding of the connection between organizational competences and organizational performance through smart factory case studies. This study suggests that SMEs should focus on enhancing their organizational competences for improving organizational performance through implementing smart factory projects.

With increasing interest and research on smart cities, there is also an increasing number of studies on urban facilities that can be built within smart cities. According to these studies, smart cities' urban facilities are likely to become high value-added industries. However, the concept of smart city is not clear because it involves various fields. Therefore, in this study, the definition of Next-Generation(N.G) Smart City Facilities with Digital Twin and Digital Chain is carried out through a multidisciplinary approach. Based on this, Next-Generation Smart City Facilities will be divided into High Value-Added Products and Big Data Platforms. Subsequently, the definition of the Digital Chain containing the data flow of the entire process built through the construction of the Digital Twin proceeds. The definitions derived are applied to the Next-Generation Noise Barrier Tunnel to ensure that data is exchanged at the Digital Twin stage, and to review the proposed configuration of the Digital Chain and Data Flow in this study. The platform definition and Digital Chain of Next-Generation Smart City Facilities proposed in this study suggest that it can affect not only the aspects of data management that are currently in the spotlight, but also the manufacturing industry as a whole.

개별 도시철도역사의 불편성에 대한 연구는 활발히 진행되고는 있으나, 역사의 유형별 특성을 고려한 환승편의시설의 중요도(importance factor)에 대한 연구는 미비한 실정이다. 따라서 본 연구에서는 구조방정식모형(SEM: Structural Equation Model)을 활용하여 도시철도역사의 유형(이용수요 및 승강장형태)에 따른 환승편의시설(이동편의시설, 정보제공시설 및 쾌적성 등)의 인과관계를 통계적으로 검증하고 도시철도역사의 유형별 환승편의시설에 대한 중요도 결정모형을 제시하였다. 도시철도역사의 유형별 중요도 분석결과 대형급 역사이면서 섬식과 상대식이 환승할 경우 정보안내시설, 이동편의시설위치 및 쾌적성의 중요도가 높은 것으로 분석되었고, 중형급 역사이면서 상대식과 상대식이 환승할 경우 정보안내시설, 이동편의시설 및 쾌적성의 중요도가 높은 것으로 분석되었다.

Globalization has diversified ethnic composition thus increased the risk of conflicts and socio-political instability in global cities. However, still the status of community facility in a global city is unclear despite its critical role to build sustainable community in global era. In Seoul, as a reaction of globalization, 19 community facilities known as the 'Seoul Global Center' have been established since 2007 by Seoul Metropolitan Government. These facilities have started to provide basic foreigner services but been transformed to foreigner service hub with multiple functions in terms of a living, a business, a labour, etc. This study explores the role of the community facility for foreigners by using the Seoul Global Center as a case study, conducting a site observation, an interview(13 staff) and a questionnaire(148 visitors). The findings are the community facility functions as a 'global platform' in forms of a policy tool for implementing the urban globalization strategy, a mediator connecting foreign migrants with local communities, an applicant for successful settlement of foreign residents, an incubator that grows human and social capital, and a base for collecting and aggregating information on foreign migrants and forming new local identities.

This paper is a technical review of the research and development results of the Korea Nuclear Instrumentation and Control System (KNICS) project and Nu-Tech 2012 program. In these projects man-machine interface system architecture, two digital platforms, and several control and protection systems were developed. One platform is a Programmable Logic Controller (PLC) for a digital safety system and another platform is a Distributed Control System (DCS) for a non-safety control system. With the safety-grade platform PLC, a reactor protection system, an engineered safety feature-component control system, and reactor core protection system were developed. A power control system was developed based on the DCS. A logic alarm cause tracking system was developed as a man-machine interface for APR1400. Also, Integrated Performance Validation Facility (IPVF) was developed for the evaluation of the function and performance of developed I&C systems. The safety-grade platform PLC and the digital safety system obtained approval for the topical report from the Korean regulatory body in February of 2009. A utility and vendor company will determine the suitability of the KNICS and Nu- Tech 2012 products to apply them to the planned nuclear power plants.
