  • Modern aircraft is facing the increase of power demands and thermal challenges. In accordance with the application of more electric technology and advanced mission requirement, aircraft system requires increase of power generation and it cause increase of internal heat generation. Simultaneously, restrictions have significantly been imposed to the thermal management system. Modern aircraft must maintain low radar observability and infra-red signature. In addition, new composite aircraft skins have reduced the amount of heat that can be rejected to the environment. The combination of these characteristics has increased the challenges faced by thermal management. In order to mitigate the thermal challenges, the concept of system level thermal management should be applied and new modeling and simulation tools need to be developed. To develop and utilize system level thermal management technology, three key points are considered. Firstly, the performance changes of subsystems and components must be assessed at an integrated thermal system. It is because that each subsystem and component interacts with other subsystems or components and it can directly effects on overall system performance. Secondly, system level thermal management requirements and solutions must be evaluated early in conceptual design process as vehicle and propulsion system configuration decisions are being made. Finally, new component level thermal management technologies must focus on reducing heat generation and increasing the availability of heat sinks.

  • The purpose of this study is to embody the integrated working management system for public works, focused on the management of surplus soil at a field of public works. The contents and results of this study can be classified into the design of working management DB for public works and the embodiment of working management DB. First, the design of working management DB for public works consists of three DBs - process management to analyze work plan and performance. for backhoe loader, working management and resources management for equipment and labor management - in connection with work and resources classification system. Secondly, the working management system for public works can describe work plan and performance on a floor plan using graphic. Based on this, the status of process and progress report with visual expression had been developed to facilitate the communications and performance of duties among staff in charge at the field of public works. This study is a specialized system for a company specializing in public works and a system that can be put into practical use if practicality is proved through test-bed with regard to business.

  • In this article, we verify to influence in the management performance by the safety management system that is recommended by the ICAO for the safety management on the airside area in the airport. Also, We present a comprehensive mediator effect that the employees perceive safety culture and safety behavior. We design how participants were selected as study the employees from 4 airports on the airside areas of the Incheon International Airport, Gimpo International Airport, Jeju International Airport and Gimhae International Airport in the Korea using the simple random sampling method. The instrument for data collection was a questionnaire, and it was developed. Data analysis was to conduct structural equation modeling. Test of the hypotheses were verified to Maximum Likelihood Estimator. As a result of the analysis, safety behavior and risk management of the safety management system found out that affect management performance. Also, the employees of a high awareness about safety policy could be seen that is a high impact on management performance through a safety culture and a safety behavior. Safety behavior has significant mediator effect within the relationship between the safety management system and management performance. So, We provide guidance of the safety policies for the safety management on the airside area in the airport.

  • The purpose of this study is to find out a way to apply the strength of American homeowners association to Korean housing management system through literature review on the legal basis, organizational composition and functions, and management models of homeowners association. Following is distinctive characteristics of American homeowners association. 1) Homeowners association is a juridical entity which 'Condominium Act' obliges residents to join. 2) The board of directors is decision maker. The covenant, however, gives residents right to act in committees. 3) Homeowners association has self-governing functions such as management of common spaces, permission of new construction and taxation. 4) Types of management are volunteers' self-management, association-employed management, full agency management, and some mixed types. Residents pay management charge by month or by quarter. This study suggests as follow. 1) It is needed for Korea to legislate the law to regulate the management system of detached houses. 2)Management system of Korea can be more efficient with volunteers' committees for active participation. Above all, architectural control committee is essential in the circumstance that reform of apartment is popular these days. 3) The management entity is recommended to have some self-governing function to talk about taxation policy with local governments.

  • Even though computer based college lecture management system was developed long ago and has been used ever since, developing perfect lecture management is not simple. The main objective of this system is to develop appropriate online lecture supportive management program suitable for college lectures. This system [ADLEMS] mainly focuses on the management of college database lectures, exams, and grades. This system supports management and grading of attendance, reports, quizzes, mid-term, and final exams. Exam management categorizes into multiple choice questions, essay questions, short answer questions, and SQL. Especially for SQL, division analysis was applied when developing grading system for more effective grade management. For essay questions and short answer questions, manual [hand] grading method was used. Every student can verify the grading process in person to alleviate the problems occurring during the grading process.

  • In EMS(environmental management system), environmental documents are very important elements to achieve ISO 14000 series certification. A organization or company which hope to acquire the certification must prescribe daily operation procedure and document them properly. Also these documents must be updated in new version. Especially, environment manual, describing EMS factors and correlation between them, is a basic document system. Therefore, a proper manual management tool help a organization or company to reduce the efforts to establish and to revise documents. So, in this paper we will present environment manual management system using database and a, pp.ication computer program.
