The typical winter heating unit heating mat. The product is to be found in the development of new water heating mat today. The product that circulates the water through the hose inside the mat with your existing heating mat electric heated mat is different from boiling water. However, no clear standards for noise and safety, consumer choice is giving confusing information about the product is low. We were to develop a high heat retention and stability than conventional sleeping mats to produce creative than traditional hot mats, heated mats general comparison with experimental results is a more efficient heat retention mat is produced.

Domestic apartment housing has been designed in accordance with the new housing supply-driven policies for a long time. As a result, its design, material production, construction, maintenance and remodeling process, rather than being systematically performed, were individually approached to cause insufficient linkage between technologies. For these problems and the supply of long life housing, active research on long life housing has been conducted in Korea since 2005. However, the existing research on long life housing has been focused on a single item with no connection made between infill systems, and no overall interface rule, resulting in no activation of the business. In this study, for the supply and activation of long life housing, we aim to analyze the problems of existing long life housing to set up its matching standards for infill systems.

The purpose of this study was to investigate the impacts of managerial behaviors on the satisfaction with management. The data were collected by means of questionnaire distributed to a stratified sample of 560 housewives in Seoul. The questionnaire consisted of 107 items was developed by the researchers. Frequency, percentile, mean, and stepwise multiple regression were used to analyze the data. The results of stepwise multiple regression analyses indicate that the wives who had more reality in planning and higher standards tended to more satisfy with managerial behaviors. The elements of inplementing such as facilitating conditions and checking behaviors were positively related with managerial satisfaction. The recommendations for the ways to increase satisfaction with management and future research were suggested.

Development of air navigation and avionics technologies led to solve the problems that conventional ATM system had. The International Civil Aviation Organization developed the Aviation System Block Upgrades (ASBU) initiative in order to harmonize global ATM planning and technology upgrades and urged to implement the recommendations for the member States. The ASBUs provide the road map to assist air navigation service providers in the development of their individual strategic plans and investment decisions. In this paper, the operational concepts in 2 performance improvement areas, Airport Operations and Globally Interoperable System and Data in ASBUs, have been summarized. In Airport Operations area the new management technologies and required systems are presented for optimizing the traffic flow in airport area and terminal airspace. Data format standards and required systems presented for information integration and usage of the new system under Globally Interoperable System and Data area.

Voltage variation caused by large loads such as arc furnace and large motors, which use the large and instantaneous currents, can cause the voltage flicker. The flicker irritates the human's eyes and also has an adverse effect on protection device, rotating machine and electronic device etc, therefore the flicker needs to be managed effectively. Recently, the Korea power quality standard has been established on the IEC standards. This paper presents the flicker management standard for distribution power system and suggests the flicker transfer coefficients for Korea power system based on the IEC 61000-3-7.

Due to the rapid increase of automobiles and daily driving distances, air pollution by automobiles is still dominant problem of large city in spite of strict emission refutation and development of reduction technologies. Among the air pollution resources of automobile , industry. electricity generation and heating. automobile keeps 51% of total nationwide air pollution in 1998 and this proportion Is increasing in large cities from 65% to 85%. To reduce these air pollution. catalytic converter and electronic engine control, exhaust gas re-circulation and evaporative emission control system have continuously developed and applied to automobiles since 1987. Also strong emission standards and emission durability warranty have enforced and monitored annually by sampling several vehicle models. But technologies and regulations are incomplete, driver should participate in reducing air pollution for himself by planning driving, avoiding unnecessary idle and air conditioning, keeping periodic maintenance and using mass transportation.

Allocation of water pollution load from loading capacity can be much essential, controversial, and its standards can be applied case-by-case to the various situations. Allocation methods to point sources are generally 'Equal effluent concentration', 'Equal percent Treatment', Loading capacity at planning stage consists of basic pollution load, development pollution load, reserved pollution load and margin of safety. But at the implementing stage loading capacity can be consisted of allocatable load and margin of safety to give more flexibility in the total water pollution load management plan. In that case, we can re-adjust and altogether use the pollution load of point sources of series and non-point sources at the implementing stage.

Unknowingly, the relationship between IT departments and their internal customers becomes that of client-supplier based on the mechanisms of marketing and competition. In addition, due to enhanced focus on the customer in the planning, development, and delivery of information service, IT service management(ITSM) has become increasingly important. These days IT management is focusing particularly on the 'de-facto' standard ITIL (IT Infrastructure Library) for implementing ITSM. It is linked as a part of CobiT’s 'deliver and support' domain, which is a framework of IT governance, and ISO/IEC 20000 is a unique international certification standards on the ITSM. This paper proposes the strategy and procedure for ITSM implementation based on ITIL with consideration of IT governance structure for manufacturing industries. It also presents a case study to share the lessons learned and results of an ITSM project.

Supply Chain Management is the process of planning, implementing and controlling the operations of the supply chain to satisfy customer requirements as efficiently as possible. It spans all movements and storage of raw materials, work-in-process inventory, and finished goods from point-of-origin to point-of-consumption. Korean Standards Association claims the Supply Chain Quality Management(SCQM) as a win-win model of organizations among the supply chains for the best product/service quality to final customers. The SCQM is focused on quality of product/service and will do much for improving manufacturing performance between customer and suppliers. Consulting-teams make every effort to design suitable solution for constructing solutions and improving the performance. This study is to analyze the performance of SCQM consulting, from July of 2007 to June of 2008, and would provide some guidelines to design the optimal consulting models and develop guidebooks.

To get competitiveness in international markets, it is essential to provide low acquisition, maintenance and operation cost with high reliability, availability and maintainability. It can be achieved by lowering development cost, making proper maintenance planning and scheduling strategies, allocating man power and logistic cost properly. In this paper, we introduces the research on making a model for estimating the life cycle cost of newly developing magnetic levitation train system in Korea. To develop a proper life cycle cost model, we broadly analyzed specs and standards and compared the life cycle cost model developed in other country. Finally, we suggests strategies to develop an unique model for the magnetic levitation train system developing in Korea.
