The recent concept of kitchen is likely defined as "Kitchen Culture" including the function of living room where all families make a conversation as well as a dinner, and it is becoming another type of the residential environment, deviating from the stereotype as only cooking area. Particularly the comfortableness of living room is closely associated with a receipt function of kitchen, and the sort & dimension & size of furniture and diversity of shapes playa more meaningful role for improving our life standard & comfortableness compared with the past, nevertheless this receipt study is carelessly handled in the first phase of construction. This Study is focusing on understanding the modern concept of kitchen where the open space concept is being introduced as more reasonable space concept, and on suggesting a solution for receipt-function of the modern kitchen concept connected with "L-D-K (Living room - Dining room- Kitchen)" space idea. In the Chapter 2 the concept of receipt and function of kitchen, the wide variety of kitchen utensils was checked up, and in the Chapter 3 the change of trends of kitchen area & receipt space was considered, and finally in the Chapter 4 the modern concept of kitchen was presented, by instancing overseas examples with receipt planning. As a consequence, the alternative of the receipt in the modern kitchen is to install an Ireland table or another type of receipt-available table (lower furniture) in the dead space between kitchen & living room for motivating smooth communication and convenient receipt, and that is the trend nowadays. Kitchen desires a rapid change. Through this kind of study it should be more researched that kitchen is not an independent space any more and lies in the mutual connection of L-D-K.

The present study suggests a concept of resources circulation type agriculture and a concept of a livestock zone related to it and evaluated economical efficiency about a possibility of the resources circulation type livestock zone based on the concept. As a result, when the resources circulation type livestock zone is operated in an area of 1,300ha, it was evaluated that the profit of 11,244 hundred thousand won per year is generated, compared to the conventional agriculture. When light and heat expenses and roughage of Hanwoo production, production of TMR forage as well as income of the energy and composting business of livestock manure at the recycling center were considered in addition to that, it was judged that the present zone development bushiness has enough business feasibility. However, it is necessary that the support regulations, etc. is constructed so that all produced compost byproducts are used at farmhouses and the system related to facility investment assurance and assistance of operating expenses is maintained. It is thought that the complement of a system is also necessary so that energy or power generation expenses can be operated in the same conditions as other new & renewable energy, and the nation's purchase of carbon credits(CDM) is investigated and systemized in the early period, and construction of a revitalization plan of the business through budget securing of the Ministry of Agriculture and Forestry related to the trade of CDM and carbon emission rights is also a business that should be urgently developed. In the future, the change of an outside environment will further promote use of the energy. Also, as people, who don't know agriculture. farm village, increase day by day because of population concentration in a city, an opportunity that can new added value through experience tourism or educational programs utilizing them is increasing. Accordingly, if programs utilizing social characteristics, such as utilization as a space of tourism. leisure. experience, system construction of bio-energy and system construction that Micro Grid or Smart Grid as a dispersed storage and generation system is stabilized, are constructed, it can be said that revitalization or success conditions of the zone is further achieved.

The purpose of this study was to investigate relationship among housewive's backgrounds, laundry practice, laundry concept and interests about environmental pollution. Two separate samples were selected to study a possible relationship among housewive's backgrounds, laundry practice, laundry concept and interests about environmental pollution in rural and urban areas. Using SAS (Statistical Analysis System), the results of this study were as follows: 1. There were significant differences in laundry practices by age, education, occupation, housing type and income. But there was no difference in laundry practice between the rural area and urban area. 2. There were significant differences between laundry awareness and age, education, occupation, housing type and income. But there was no difference in laundry awareness between the rural area and urban area. 3. There were significant differences in environmental interest by age, education, occupation, housing type, income. There were significant differences in environmental interest between the rural and urban areas. 4. There was a significant relationship in laundry awareness, environmental interest and laundry practices between the rural area and urban area. It was concluded that a housewife who has a greater environmental interest showed greater awareness in laundry practices.

Meaning of expressive words on the beauty of clothing is to comprehend inclusively with subjectivity and sensitivity. Suppose that meaning of the words was analysed, the study would be found type structural through a type of meaning component and inner reciprocity of elements. Category in the Beauty of Clothing was to consider various languages on beauty of clothing as the concept of the type. The purpose of this study was to clarify the concept structure of Categories in the Beauty of Clothing. In this paper 'Chic' and 'Dandism' were analyzed. As the result of the study, it is constructed at three different dimensions. They were the Beauty of phenomenone such as surface level, the Beauty of essence such as element level, and the Beauty of process that existed between the surface level and the element level. In addition, the idea words of each dimension were as follows; The Beauty of phenomenone was expressed 'refinement', 'wisdom' and 'originality'. The Beauty of essence was included 'subtlely', 'grace', and 'sence/reason'. The Beauty of process was included the method of 'harmony' and 'proficiency'.

To overcome the limit of a point-point connection type service which is common to the ISDN bearer services, a new concept of network element, Service Node, which can provide multiparty connections and control the teleservices on those connections is proposed. This will support conference type multiparty multimedia services among normal ISDN subscribers. In this paper, as a primary study on this concept, we deduce some attributes of the general conference type services and examine the methods and procedures to provide that kind of services through the ISDN. Based on this study, we also define the general requirements and basic structure for the Service Node realization, thus give shape to the concept of it.

The IHX (Intermediate Heat eXchanger) for a pool-type SFR (Sodium-cooled Fast Reactor) system transfers heat from the primary high temperature sodium to the intermediate cold temperature sodium. The upper structure of the IHX is a coaxial structure designed to form a flow path for both the secondary high temperature and low temperature sodium. The coaxial structure of the IHX consists of a central downcomer and riser for the incoming and outgoing intermediate sodium, respectively. The IHX of a pool-type SFR is supported at the upper surface of the reactor head with an IHX support structure that connects the IHX riser cylinder to the reactor head. The reactor head is generally maintained at the low temperature regime, but the riser cylinder is exposed in the elevated temperature region. The resultant complicated temperature distribution of the co-axial structure including the IHX support structure may induce a severe thermal stress distribution. In this study, the structural feasibility of the current upper support structure concept is investigated through a preliminary stress analysis and an alternative design concept to accommodate the IHTS (Intermediate Heat Transport System) piping expansion loads and severe thermal stress is proposed. Through the structural analysis it is found that the alternative design concept is effective in reducing the thermal stress and acquiring structural integrity.

This paper presents a new design concept for ocean nuclear power plants (ONPPs) using a tension leg platform (TLP). The system-integrated modular advanced reactor, which is one of the successful small modular reactors, is mounted for demonstration. The authors define the design requirements and parameters, modularize and rearrange the nuclear and other facilities, and propose a new total general arrangement. The most fundamental level of design results for the platform and tendon system are provided, and the construction procedure and safety features are discussed. The integrated passive safety system developed for the gravity based structure-type ONPP is also available in the TLP-type ONPP with minor modifications. The safety system fully utilizes the benefits of the ocean environment, and enhances the safety features of the proposed concept. For the verification of the design concept, hydrodynamic analyses are performed using the commercial software ANSYS AQWA with the Pierson-Moskowitz and JONSWAP wave spectra that represent various ocean environments and the results are discussed.
