This paper deals with the design and the development of user interface for a high speed linear programming solving system. The general users' educational and practical requirements are analyzed and the functionalities that should be implemented for the requirements are designed. The user interface of the system consists of various carefully designed built-in commands that perform the functionalities. The names of the build-in commands are chosen to enhance the users' convenience. We also address the various factors that should be considered in the design of the linear programming solvers when integrated with the user interface. As one of user-friendly environments, data input system that can understand user-written arithmetic form is added to our user interface system. Finally, we compare our system with other user interface systems.

Life-cycle assessment (LCA) is often employed to quantify the environmental impact of a product in a comprehensive manner. The aspects of performance and usability as well as that of eco-friendliness should be considered in an integrated manner for the market competitiveness of an eco-friendly product. The present study developed a product improvement plan for an eco-friendly electric heater by benchmarking two small-size electric heaters (companies 'H' and 'T') in terms of performance, usability, and eco-friendliness. The performance measurements such as temperature, humidity, wind speed, noise, and power consumption were collected while the two heaters were operated in a laboratory setting. Then, the usability evaluations such as aesthetics, operation satisfaction, performance satisfaction, and overall satisfaction were surveyed for the two heaters using a 5-point scale (1 for very unsatisfied and 5 for very satisfied). Lastly, the LCA analysis was conducted by following the six-step process of eco-friendly product design provided by KEITI. The analysis results of the two products being integrated with the aspects of product, service, and user, four design improvement directions such as eco-efficient, smart, modularized, and user-support were recommended for an eco-friendly electric heater. These proposed concepts would be useful to develop an eco-friendly electric heater design with a high level of market competitiveness.

In accordance with recent highly advanced economic growth, the demand of leisure life is quite increasing, and also the increase of nature-friendly leisure with health-pursuing concept where human -being enjoys pleasant environment, is to me said as one of recent social traits. Accordingly, it is research the present situation and characteristic of the popularized housing-type accommodating facility, and then this study has discussed on the method how to plan the interior space of such facility to meet with environmental -friendly peculiarity and the object for health enhancement. At first, the program which applied the sustainable design techniques should be preceded, and when planning of interior space, the management method and space planning on the facility and the system should be properly considered in order to enhance the user's health. So to speak, in order to keep and promote the space user's health, those proposing methods such as the followings have been suggested likely as, consideration regarding to air-ventilation and lighting, usage of environmental-friendly material, use of life drainage, custom-typed plane planning, utilization of balcony space, storing furniture and systemization of kitchen space, themed bathroom, inducement of indoor-gardening, and so on. It is expected that this could be applied very usefully to the space plan of the small-scaled housing-type accommodation under planning to develop or renovation.

In 1990s, interest on Environment has been increased and Environment-oriented consumer's economic power accelerated the trend of preference for 'Environment-friendly material'. Moreover, the concept of 'Sick Building' Syndrome has been spread to the public and solution for the syndrome is required. 'Environment-friendly material'means that the material used is not harmful for the user's health, and on top of that, causes least harm to the environment during production/scrap process of the material itself. Decision of designers and architectures, as a result, is really crucial tot he environment issues. Above all, selecting the most environment-friendly material and design among possible candidates is natural and cost saving way. In the paper, couple of Evaluation Criterium for Material Selection are analyzed and objective linkage has been identified. With the result of analysis, methodology to minimize damage on environment during whole life cycle of the Interior Design has been sought for.

This study beings from solving problems of permanent rental housing with environmentally-friendly planning factors to raise quality of life. Environmentally-friendly planning factors of permanent rental housing are derived from the study of references and green building certification systems of other countries. Surveys of inhabitants and experts give weights on these factors. Inhabitants do are focussed natural ventilation, life cycle cost, operation and maintenance cost. This reflects their interest in indoor amenity and a burden on the cost. Experts put more weights on pedestrian spaces considering the old and feeble persons and block planning. Besides, T-test pointed out that there are meaningful differences in land use between inhabitants and experts. Though inhabitants' opinion has priority because they are real user, experts' opinion which has the variety and the view in the long term should be reflected.

The purpose of this study is to evaluate the satisfaction level and to analyze the factors in the environment friendly consolidation canals. In this study, the survey consists of four parts, such as the actual status of environment friendly canals, satisfaction level for each items, overall satisfaction level and the personal features of the users. Total 128 samples out of 140 respondents were used for the final analysis. Analysis of the satisfaction level were fulfilled to survey results such as the basic statistics and the correlations of variables, in addition, dispersion analysis for two user groups were carried out. Function of canal, water quality, landscape, and convenience facilities were chosen as independent variables in the model. Residents in Yeoju area were satisfied with water quality, water quantity and the function of canal. And residents of Yeonggwang area were satisfied with the convenience facilities and the function of the newly consolidated canal.

Recently, many auto makers and OEM are now developing various telematics control units(TCU). TCU has an embedded OS and many user-friendly services inherently and frequently the driver operates the TCU on driving a car. Although the TCU has some accident resistive functions, secondhand accidental problem arose. Current Korean domestic TCUs have some interfaces such as push-button, touch screen, voice recognition and etc. But, because of operational complexity, technical limitation, it has not sufficient user-friendly interface. In this paper, to overcome this problem, haptic devices are considered. We present haptic devices and applications on the basis of that of U.S. Immersion co. and also BMW's iDrive technology.

A new query method, called query by visual keys, is proposed to aim easy operation and efficient region-based image retrieval (RBIR). Visual keys are constructed from representative regions/subimages in a given image database, and the database is indexed with visual keys. A system on PC is presented, where text retrieval techniques are applied to the image retrieval with visual keys. Experimental results show that one retrieval is done within 4ms and that the proposed system achieves the comparable retrieval precision (with user-friendly operation and low computational cost) to conventional region based image retrieval systems

Recently, due to the widely use of personal computers and internet, many computer users requested intelligent system that can cope with various types of requirements and user-friendly interfaces. Based on this background, researches on the intelligent agent are now activating in various fields. In this paper, we modeled, designed and implemented an intelligent agent system for pattern classification by adopting intelligent agent concepts. We also investigated the pattern classification method by utilizing some pattern classification algorithms for the common data. As a result, we identified that 300 3-dimensional data are applied to three pattern classification algorithms and returned correct results. Our system showed a distinguished user-friendly interface feature by adopting various agents including graphic agent.
