It was already proved that ATM stability and flexibility of service application, but because of the various characteristics of traffics and the QoS on user demand caused by them, there are a lot of researches for traffic management method. However, there are a few of researches for ATM routing method acting on traffic management practically. In this paper, we focus on multi-path routing method transporting cells with multiple paths and compare this method with existing single path routing method and analyze multi-path routing method into three elements with simple formula and propose anew methods improving the performance of ATM routing and simulate these methods.

According to the recent development of network technology, the demands of users are diversified and the needs of multimedia traffic are increasing. In general, UDP(User Datagram Protocol) traffic is used to transport multimedia data, which satisfied the real-time and isochronous characteristics. UDP traffic competes with TCP traffic and incur the network congestion. However, TCP traffic performs network congestion control but does not consider the receiver's status. Thus, it is not appropriate in case of streaming services. In this paper, we solve a fairness problems and proposed a network algorithm based on RTP/RTCP(Real-time Transport Protocol/Realtime Transport Control Protocol) in view of receiver status. The POBA(Priority Ordered Buffer Algorithm), which applies priorities in the receiver's buffer and networks, shows that it provides the appropriate environment for streaming services in view of packet loss ratio and buffer utilization of receiver's buffer compared with the previous method.

The impaired person and the elderly who has hearing loss have been continuously increased and these people's desire for participating society as a producer has been increased also. So they strongly request the aid device which can compensate their handicap. The healing aid telephone is one of the basic aid devices that helps the hearing impaired to communicate with other people and to acquire useful information. We design the new model of the hearing aid telephone and test it's efficiency in three fields - electrical, speech perception, user test. From the result of the test we certify that the new model is better for the hearing impaired to understand the meaning of telephone speech than the old general models. We expect that the advanced healing aid telephone can be developed by the research about speech perception characteristics of the hearing impaired in engineering and clinical side.

This research is aimed to develop the functional clothing designs for disabled women in the manner of investigating design preferences among them by means of questionnaire and interview with 150 disabled women as respondents and interviewees. The findings of this research are summarized as follows: 1. Regarding satisfaction with ready-made clothes, the respondents answered 'very satisfied' (1.6%), 'usually satisfied' (14.1%), 'moderate' (20.3%) and 'unsatisfied' (53.1%), suggesting that they had been generally unsatisfied with ready-made clothes. 2. There were more disabled women preferring to ready-made clothes with one-grade bigger (loose.) size than the actual one (53.1%) instead of completely fitted size (43.8%) when they purchased such clothes. This result indicates that they prefer to ready-made clothes with bigger size than the actual one because most of such clothes are made up of non-elastic materials which may be unfavorable for wearer's activities. 3. It was found that primarily worn upper garment among them was T-shirt (59.4%). The reason may be that T-shirt is favorable for using prosthesis and orthotics such as wheelchair, walking stick and crutches thanks to its remarkably high activity as well as simple to maintain, compared with other kinds of upper garments. 4. Regarding preferences to functional clothing designs, the primarily worn lower garment among them was trousers (85.9%); the reason was easiness to move. The main reasons of avoiding to wear a skirt included 'difficult to move' (40.6%) and 'exposed disabled region' (30.3%). Accordingly, functional clothing for disabled women should be developed in consideration for their individual characteristics of disability associated with the disabled region such as wheelchair user, crutch user or brace user, In addition, the designs should be made so that they are not different from those for non-disabled people.

The compartmentation model is represented by the characteristics and geometric information of the spaces defined by the structural members which are used for the boundary planes of the compartment. For the efficient compartment modeling a program performing the compartmentation design by the chopping and merging method was presented by authors. In this research, the development of an interactive ship compartmentation modeller is introduced. It is natural that the value of the program lessens if the input process is complicated and uneasy, even though the internal techniques for the compartmentation modeling are superior. In this paper, a method for the convenient input is proposed and implemented with the help of a graphical user interface technique. The modeling method introduced in this paper performs an efficient compartmentation modeling fast and conveniently by the solid modeling concept and the graphical user interface.

Providing efficient recording information services has become vital in a utilization-oriented records management environment and further increasing the importance of the quality of the services offered. This study is a preliminary study to propose improvement measures by applying Quality Function Development (QFD), a quality control method, to the National Archives of Korea (NAK) and Records Information Service. The quality dimensions of the recording information service were analyzed, and specific user requirements were derived. Through this process, the user requirements' questionnaire was developed, reflecting the characteristics of the NAK, and the application model of QFD was designed based on its prior study. Based on the QFD application model proposed, the results obtained by performing the QFD step by step can be expressed in House of Quality (HoQ), which can be used as a basis for service design.

With the recent development of manufacturing technology and the diversification of consumer needs, not only the process and quality control of production have become more complicated but also the kinds of information that manufacturing facilities provide the user about process have been diversified. Therefore the importance of big data analysis also has been raised. However, most small and medium enterprises (SMEs) lack the systematic infrastructure of big data management and analysis. In particular, due to the nature of domestic manufacturing companies that rely on foreign manufacturers for most of their manufacturing facilities, the need for their own data analysis and manufacturing support applications is increasing and research has been conducted in Korea. This study proposes integrated analysis platform for process and quality analysis, considering manufacturing big data database (DB) and data characteristics. The platform is implemented in two versions, Web and C/S, to enhance accessibility which perform template based quality analysis and real-time monitoring. The user can upload data from their local PC or DB and run analysis by combining single analysis module in template in a way they want since the platform is not optimized for a particular manufacturing process. Also Java and R are used as the development language for ease of system supplementation. It is expected that the platform will be available at a low price and evolve the ability of quality analysis in SMEs.

Recently, due to the development of interactive media, Interactive Typography, which explores user input and interaction is under development. Unlike traditional typography which has a fixed nature, the flexible and fluid nature of Interactive Typography and Interactive System, enables diverse results. In this study, I have developed an Interactive Typography art piece based on theoretical research. By reviewing books, papers and articles, I have tried to define the meaning and characteristics of Interactive Typography. In understanding the concept of Interactive System, I have borrowed the concept of mathematical function. Based on the research, I have designed and developed an Interactive Typography piece, 'Interactive floral type' by using Adobe flash action script. This piece explores the beautiful shape of each alphabet letters and transforms individual character into a 'flower' shape through user's mouse and keyboard input. Depending on the input the size, color, and layout and motion of text changes in real time to change the letters into beautiful flowers.

The prosthetic leg is a device that performs walking instead of a amputated lower limb, and require a change in locomotion mode by providing the user's intention to respond to a discontinuous locomotion environment. Research has been conducted to detect the users' intentions through biomechanical features inside the socket that directly contacts the cut site in demand for natural locomotion mode changes without external control equipment. However, there is still a need for a sensor system that is suitable for the internal environment of the main body and socket of the cut site. Accordingly, this paper proposed a film-type sensor system that is suitable for the main body characteristics of the cut site, is not affected by the temperature and humidity conditions inside the socket, and is easy to manufacture in various sizes. The proposed sensor is manufactured base on Velostat film and takes into account the pressure measurement characteristics that vary with size. Through the experiment, the change in the internal pressure of the socket due to the intentional posture performance of the wearer was measured, and the possibility of detecting the intention to change the locomotion mode was confirmed.

Nutrition is important in the management of diabetes mellitus, however, there are few little education materials specifically designed for older adults. The objective of this study was to develop nutrition education materials for prevention and management of diabetes moll for older adults. Materials developed were a booklet and four leaflets. The contents of materials were based on lesson plans. After several revisions of the draft of materials, illustrations and icons appropriate to the contents were designed using illustrator 9.0 and Photoshop 6.0. The booklet was composed of five chapters and 40 pages. The first chapter began with an introduction about diabetes and diabetes management by diet, exercise and medication. The second chapter dealt with ideal body weight, calculation of adequate caloric intake and food exchange list. The third chapter provided information for meal planning and sample menus. The fourth chapter focused on practical tips on nutritional care of diabetes, by providing tips on reducing sugars, fat and salt, and suggestions on eating for special occasions. The fifth chapter dealt with information in case of low blood sugars, exercise and foot care. The topics of the four leaflets were “Diabetes, what is it and care”, “Food exchange list and meal planning”, “Healthy eating for diabetes”, “Special care for diabetes low blood sugars, exercise and foot care” Each leaflet was composed of six sections and was printed in large paper (B4 size) for older adults. The draft of educational materials were re-viewed by four nutrition professionals and finally pilot-tested with ten adults aged 50 and older. The characteristics of the developed materials are as follows, i) messages are delivered using simple, specific information, ⅱ) messages focused on practical applicable tips, ⅲ) various pictures, illustrations and artwork were created and inserted to enhance understanding and interest, ⅳ) sections including risk factor assessment, calculation of ideal body weight and meal planning were designed to induce the user's participation, ⅴ) sample menus and food pictures were inserted in the booklet, vi) characteristics of older adults and transformed characteristics are diversely used to help the user feel familiarity. These materials are self-explanatory and can be used by older adults. These materials also can be used widely in nutrition education at public health centers or senior centers.
