The district heating system supports currently 1.3 million of houses in South Korea, and it is composed of two main parts: provision and distribution. For the provision part, Korea District Heating Corporation supervises the system with proper devices and experts, whereas for the distribution parts, there is no main supervision system and it depends highly on experts although it is very difficult to find the proper experts. In this paper, we consider IoT based remote management system for district heating distribution to properly supervise heating distribution by experts and/or programs remotely.

Objectives: Since the material safety data sheets(MSDS) submission and non-disclosure review system was introduced in January 2021, the implementation status of MSDS for chemical manufacturing and importing workplaces being supervised for the first time. Methods: A supervisory team consisting of two labor inspectors and one from the Korea Occupational Safety and Health Agency directly visited the selected workplaces to check compliance with the MSDS system as a whole. Results: As a result of supervising 214 chemical substance manufacturing/importing workplaces, a total of 241 violations of the law were found in 121 workplaces, or 57% of them. In response, the Ministry of Employment and Labor took legal action on 8 cases in 6 locations, imposed a fines totaling of 249.69 million won on 120 chemical handling workplaces, and took action to correct the violations immediately. Conclusions: Major violations were in the order of non-request for warning signs, non-submission of MSDS, non-execution of MSDS training, and non-posting of MSDS. This shows the reality that employers who handle chemical substances are sufficiently communicating chemical information to workers. In the future, the government will actively implement preparation and submission support and system guidance for the implementation of the MSDS system, while making efforts to ensure that the MSDS system works well in the field through thorough on-site supervision in the future.

Research on information system supervision services was mainly interested in supervision service standards or legislation, but this study identified the factors that ordering agencies consider important when introducing/advancing information systems and then looked at the information system from the ordering agency's perspective. According to the research results, (1) ordering organizations consider innovation factors the most important when introducing/advancing information systems, (2) organizational culture and the will of the CEO are still important factors, and (3) innovation factors are more important than technology factors. The results of this study indicate that the participation of information system supervision experts is required not only from the technical aspect of the constructed information system, but also from the organizational aspect of the ordering agency.

CBTC(Communication Based Train Control) System can improve train operation efficiency by realizing moving block system which makes a continuous train interval control in accordance with the position and speed of train. Adopting radio transmission to make a continuous detection of train position and transmit the control data from the ground to a train, CBTC needs dedicated train operation and control algorithm which should be quite different from the conventional track-circuit-based train control system. This paper provides a train operation display and control algorithm for CBTC system in making train interval control, train route control and train supervision. Signalling pattern diagram is devised to analyze the train interval control mechanism of moving block system, and interlocking logic is devised to represent the train route control mechanism of moving block system. For train supervision, train occupation status on railway are displayed by using the segment which virtually divide the whole railway. The proposed method has been successfully applied to the development of CBTC system for the standardized AGT(automatic guided transit) which is under construction now in Korea, and also can be applied to any other CBTC system.

Educational programs for promoting occupational safety and health have widely been established in advanced countries, such as United States and Germany, in the area of disaster prevention Focused attentions and investments for safety and health education have been placed especially for small and medium sized companies. Recently, information technologies have also been applied for the development and management of educational programs in those countries. It is also worth noting that a wide variety of incentive systems has been implemented for managers and workers to voluntarily Participate in safety and health education. Based on the brief survey on incentive systems in advanced countries, this study proposes two different incentive models, such as 'Supervision Exemption Model for Participants in Safety and Health Education' and 'Compensation Program fur Educational Expenses and Losses', which may efficiently be employed in Korea. These incentive models may contribute to revitalizing the occupational safety and health education which has recently been dwindled due to the changes in governmental regulations.

This paper uses 135 Licensed Operator Event Reports (LOER) from Chinese nuclear plants to analyze how safety culture affects unsafe behaviors in nuclear power plants. On the basis of a modified human factors analysis and classification system (HFACS) framework, structural equation model (SEM) is used to explore the relationship between latent variables at various levels. Correlation tests such as chi-square test are used to analyze the path from safety culture to unsafe behaviors. The role of latent error is clarified. The results show that the ratio of latent errors to active errors is 3.4:1. The key path linking safety culture weaknesses to unsafe behaviors is Organizational Processes → Inadequate Supervision → Physical/Technical Environment → Skill-based Errors. The most influential factors on the latent variables at each level in the HFACS framework are Organizational Processes, Inadequate Supervision, Physical Environment, and Skill-based Errors.

XML was applied to web-Based application system for efficient data supervision and processing. Also, ASP permitted embodiment of easy web-Based programming, and UML is studied by the new alternative of system modelling techniques. Thus, In this paper see embodied student taking a course application management system using XML, ASP, UML. This was composed, and used XML for effective data supervision and processing by student mode and administrator mode. Also, It used UML for systems analysis and design, and whole system implemented by ASP. And, Database implemented to used in MS-ACCESS, and it used java Script language for efficient practical use of web document.

The purpose of this study is to maximize project efficiencies in construction management by analyzing hierarchical factors that effect in project supervision system, and consequently constructing managerial CSF(Critical Success Factors). For this study, the tools for evaluating operating and management abilities of site engineers are built from analyzing status and issues, deducing influence factors and rating cardinal scales of these factors from survey results. These evaluation tools are reflected to the construction supervision decision making process so that can improve project management effectiveness.

Enforcement of an arbitration award is an extremely important issue in arbitration. Arbitration, as a dispute settlement process, is rendered meaningless if it is not possible to enforce an award rendered by an arbitration tribunal. On the other hand, the present international arbitration system guided by the New York Convention and UNCITRAL Model Law is established on the dual supervision from the national courts. The nationality of the international arbitral award closely relates to the supervision of the national court, and the national court is entitled to decide the nationality of the international award in accordance with the conditions set in its own domestic law. The national court may set aside arbitral award made in its territory while the foreign court may refuge enforcement of foreign arbitral awards according to its own law and international convention to which it is a party. The conditions set in the Arbitration Law of the People's Republic of China are in agreement with those set in the UNCITRAL Model Law. The Chinese national court is entitled to set aside international awards made in China in accordance with the Chinese Law. The purpose of this paper is to clarify the Chinesr practice on the revocation of international commercial arbitral awards.
