In this paper, we describe the structure, function and the design factor of common module for KOMPSAT-2 OBC, which will be launched in 2005. By analysing OBC's performance, we can know the throughput and how much improve performance than KOMPSAT-l. it is used in the satellite mission design by system engineer. We verify the usefulness of common module for KOMPSAT-2 OBC through environment test.

In order to design the aspherical lens, the revisions and the steps of the mathematical method are influenced with a lot of variables. The accuracy of the aspherical lens can be changed by these variables. Besides, to design the aspherical lens, many mathematical functions should be used. To use these mathematical functions is protected by patent administration. Therefore it is very difficult for most of developed countries to use them. This fact has been interrupting not only the development of the technique of a design of the aspherical lens but also the development of the equipments of optics. Because approximate values are used in most of common programs which create the aspherical lens : basically these common programs have variations. Therefore these aspherical lens are not accurate. In the paper, we calculated accurate values by using the refractive index of lens. Based on these data, wee created self-operating design programs. Consequently, our lens is more accurate than the aspherical lens which is created by the common programs influenced with approximate values. The used programs belonging to AutoCAD is Visual LISP.

The main issue in the current software development is the development of a reusable and flexible software. Already many successful software development experiences have been proposed to extract patterns of common look, depending on the software environment or depending on the nature of the module you want to implement. Can develop the software quickly and accurately to select fit for the purpose of developing and reuse using experienced patterns. These developments are depending on the success and failure become a new experience and reuse again. Apply design pattern in software development is required, was not an option. In this paper, design and implement to a common framework applied design patterns for the development of reusable software using .NET Remoting in one of the technologies of distributed communication services.

In order to establish the effective community village as planned, it is the most important factor in residents' participation at the stage of design process. Especially, community space, which is commonly used by all members, must be designed through consultation process of community members themselves to accommodate the needs of various daily activities. So, in this study, the participation process to design the common community facility is developed and the actual residents' participation workshop was conducted in Baek-Hwa village, which is being built on South Korea. Also, the space of community facilities was designed based on the direct opinions and needs of actual residents obtained by workshop process. The workshop was conducted two times: the first workshop was conducted for the design of common residents' facilities and the second was for trying to utilize the virtual designed space. During the workshop process, it is found that the positive participation of members of village is naturally occurred to design residents' space in the workshop process. As a result, most people want to make the space of gym, library, and dining room in spatial configuration. Among them, the hobby room was highly demanded. There is lots of demand for the joint activities and training program in common activity fields. Also, the prediction of the various occurrence so fun expected situations was requested in the game of creating rules and role-playing. In the conclusion, it was acknowledged the necessity of residents' participation design and the importance of communication between architects and residents for decision-making.

This study analyzes the athleisure wear purchase status, wearing conditions, and design preferences of men in their 20s and 30s and provides basic data for the development of men's athleisure wear that reflects consumer preferences. An online survey was conducted on 200 men from August 23 to August 27, 2023. The questionnaire consisted of a total of 48 questions, including 8 questions about the respondent's general information, 19 questions about the purchase status of athleisure wear, 6 questions about the status of wearing athleisure wear, and 15 questions about athleisure wear design preferences. The survey results are as follows. The most common motive for exercise participation was 'maintaining health.' 'Nike' was the most preferred and purchased brand among athleisure wear brands, and the main place of purchase of athleisure wear was 'Internet and mobile shopping malls', reflecting the recent purchasing trend of the MZ generation. When purchasing athleisure wear, the most common selection criterion was 'design', followed by 'fitting comfort', 'possibility to use as daily wear', and 'price'. The most common route to obtain purchase information was 'Internet search', and the 'overall satisfaction' with athleisure wear was found to be satisfactory with an average of 3.83. The most common reason for wearing athleisure wear was 'because it is comfortable to do activities', followed by 'because it can be used as everyday wear'. Lastly, 'black', 'short-sleeved t-shirt', 'short length' sleeve, 'round neckline', 'waist length', and 'relaxed loose fit' were preferred for the top design, and 'black', 'shorts', 'full elastic type' waistband, 'regular fit that fits the body well' were preferred for the bottom design.

The objectives of this study is to create an environment which students could apply effectively through focused on the innovative methods of education and CAD course contents. The facts which were able to figure out from this study were as follows ; 1. After the analysis of the CAD course contents of the american universities, their common contents were in order of introduce to Computer Aided Drafting and design with Auto CAD/ provide fundamental knowledge of the application for use in design/ examine and how this effects 2 D image and model creation/ CAD as a design tool . Over all trend of CAD course contents of interior design program in american university is moving toward utilizing CAD as a design tool. 2. On the other hand, common contents of our local universities were simply introducing CAD. It means that our course contents are more methodological and theoreatical . And american university's program is focused on problem solving solution as a design tool.

This paper propose a "Active common-mode voltage damper circuit" that capable of a suppression of a common-mode voltage produced in the PWM VSI. The four level half-bridge PWM inverter circuit and common-mode transformer are incorporated into the "Active common-mode voltage damper" the design method of which is presented Effect of "Active common-mode voltage damper" in this paper verifies a propriety and effectiveness in 2.2[kW] induction motor drive using IGBT inverter. Experimental results show that "common-mode voltage damper" makes contributions to reducing a high frequency leakage current and common-mode voltage.leakage current and common-mode voltage.

The purpose of this study is to analyze the preference of spatial elements for common space planning in senior congregate housing. For the study, 500 potential consumer's residing in Seoul was surveyed using the questionnaire in the social survey methodology. As for the common spaces, gardens, treatment, and exercise rooms were preferred. A combination of both separate and group arrangement of the buildings was preferred, indicating that people wanted separation of the common space and the individual living units. Second, people preferred sharing parts of the common space with their neighbors and as is the traditional custom, preferred to take off their shoes at the entrance to individual units. Third, for the furniture and facilities, they wanted the manager room in the lobby, the small meeting rooms in the public dining room, a fitness center in the activity room, the rack or alcove to store items in front of an individuals unit in the hallway, a chair to sit down in the elevator, and the chair to rest on the stairway landing. Fourth, in terms of priority for planning the senior citizens' community housing, safety, familiarity like a regular home, reduced isolation and loneliness, sense of belonging, economic factors, aesthetic appreciation, daily life supplement, variety, and self-identity were answered in that order.
