  • Traceability links are logical links between individual requirements and other system elements such as architecture descriptions, source code, and test cases. These are useful for requirements change impact analysis, requirements conflict analysis, and requirements consistency checking. However, establishing and maintaining traceability links places a big burden since complex systems have especially yield an enormous number of various artifacts. We propose a feature-oriented requirements tracing method to manage requirements with cost benefit analysis, including value consideration and intermediate catalysis using features. Our approach offers two contributions to the study of requirements tracing: (1)We introduce feature modeling as intermediate catalysis to generate traceability links between user requirements and implementation artifacts. (2)We provide value consideration with cost and efforts to identify traceability links based on prioritized requirements, thus assigning a granularity level to each feature. In this paper, we especially present the results of a case study which is carried out in Apartment Ubiquitous Platform to integrate and connect home services in an apartment complex in details.

  • In spite of the bad conditions of fashion companies: the number of licit wear consumers in Korea are increasing because knit wear gives a body with an comfort action. Domestic knit wear industry, however, doesn't have any standard fur satisfying consumers'needs and for quality estimation on that. So we examined the knit wearers'conception of the quality to broaden the knowledge of knit wear and produce better products. The purpose of this study was to find out the factors of wearer's perception. This study carried out through a qualitative approach. The subject of this study were 17 single women who were 20's and living in Seoul and Kyoungki province. The item of this questionary was as follow: 1) what they know about knit wear and how much they are satisfied with that 2) what the wearers think the problems of knit wear are 3) how knitted wear industry can satisfy consumers's needs and take into account consumer feedback in product development The results of this study were summarized as follows. 1. The wearers had no knowledge about materials, sewing methods, patterns, knitting methods, and gage. 2 The wearers didn't recognize the differences between the products by famous brand and obscure conventional market. For that reason, the high price knit wear wont satisfy wearer. 3. The wearers didn't prefer the revealing their body shapes. 4. Laundering was the big problem which was they chosen the knit wear. They take it for granted that the knit wear needs dry-cleaning or hand-washing. Knit wear industry tries to make it easy laundering by development knit material.

  • This study was designed to find out the relations between the major investment decision-making behaviors and profitability of the hospital. A total of 57 hospitals were analyzed on this study. The major findings were as follows; 1. Among the types of the investment decision-making, major factors affecting the profitability were where the top management belongs among the defender, analyzer, prospector, and reactor type. Other factors were whether or not hospital analyzes which is more economical between the purchase by cash and lease of the medical equipment and whether or not hospital changes the decision before the actual investment. 2, Among the types of the investment decision-making, major factors affecting the financial structure and efficient operation of the assets were ranking of the priority and whether or not hospitals can get enough revenue and cash flow when hospitals have to borrow a big amount of fund from outside. 3. Among the financial indices regarding the financial stability, major factor affecting the profitability was fixed assets to long-tenn capital. Other factors affecting the financial structure and efficient operation of the assets were value added to medical equipment, normal profit to medical equipment, liability to total assets, current ratio, value added to payroll expenses. 4. Investment decision-making behaviors are partially influencing on the financial structure and efficient operation of the assets. However it was proved that the profitability was the most influencial factor than other factors related with the operation of the hospital. 5. To improve the irrational investment decision-making behaviors strategic management system should be introduced, and the top mamagement's investment decision-making style should be changed from reactor and analyser styles to prospector and reactor ones.

  • As the most common application development of software development time, error-free quality, adaptability to frequent maintenance, such as the need for large and complex software challenges have been raised. When developing web applications to respond to software reusability, reliability, scalability, simplicity, these quality issues do not take into account such aspects traditionally. In this situation, the traditional development methodology to solve the same quality because it has limited development of new methodologies is needed. Quality of applications the application logic, data, and architecture in the entire area as a separate methodology can achieve your goals if you do not respond. In this study secure coding, the big issue, web application factors to deal with security vulnerabilities, web application architecture, design procedure is proposed. This proposal is based on a series of ISO/IEC9000, a web application architecture design process.

  • This study aims at explaining locality of living space which is changing drastically by exploring change of land utilization, living space and condition in Yeo-ju, an agricultural area around Seoul. The conclusions are as follows. 1. Agricultural land utilization tends to decrease, while civic land utilization tends to increase. 2. Change of living space due to transportation development is remarkable. Big ferry town (Yeoju-town) grew to a city, while small ferry town fell away. 3. In villages on slow urbanization, houses or lands are deserted. 4. In villages, there has been increasing number of recreational farm for urbanite. 5. In 80% of villages, there has been an increasing number of part-time farmers. 6. Most serious social problem in Yeo-ju is incompetence in agricultural activity after UR. In sum, Yeoju is now an area where the pace of urbanization is very tardy. However, this area, as an changeable area just before speedy urbanization, is expected to be urbanized drastically on condition that transportation develop. When plans suitable for this town are set up, Yeoju is expected to be a comfortable city.

  • Three-story Stone pagodas in Gameunsa Temple site, one of the early staged stone pagodas, has been known as a standard of Silla stone pagodas. A stone pagoda is not only a stone art work and but also a stone architecture. In understanding the stone pagoda it is very important to be approached with technological side in which we can investigate the stone pagoda deeply and as well as to have been approached with art historical view. Also it needs that we should see the stone pagoda in view of structural safety. We can get many high technique from our ancestors who made Gameunsajiseoktap. 1. To reduce any deformation such as relaxation and sinking of members which is caused by a heavy load the members such as the lower tier of the base is made up of the foundation stone and side stone in each, comprising one stone. 2. A special construction method for connection between wall stone and column stone in stereobates was invented. It is to make column stone projected partially and wall stone be caved in that two members should be jointed well. This unique method is not used any longer after the three-story Stone pagodas in Gameunsa Temple Site. 3. In each side upper and lower member are not engaged as the size of roof stones and support stones of roof stones are different. It can be done for a distribution of perpendicular load and a prevention for relaxation of members. 4. It makes sure that to make upper ends of support stones 10mm lower was to be avoid upper loads to it judging from survey in disassemblying east pagoda. It proves that ancestors who made this stone pagoda had a technique to understand the structural matters to make small members as big as possible, not to engage in joint, to avoid in ends of members from upper load.

  • 1. The concept about Jeok-chwiui(積聚) has been around since before "Hwangje-Naegyeong". Since "Hwangje-Naegyeong(黃帝內經)", Sik-jeok(食積) was made mention of specifically. In "Yu-gyeong(類經)", it is said that Sik-jeok is a combination of our body fluid and blood by bad eating and sleeping habits. 2. In the narrow sense Sik-jeok is indigestion and broadly it is inappropriately stagnant fluids in our body. 3. If studying on Sik-jeok in Dong-ui-bo-gam 1) It is located on the right side, in the epigastric region and between the skin and fascia. 2) The cause of Sik-jeok is indigestion, inappropriate temperature and weak stomach. 3) Symptoms of Sik-jeok are very diverse such as sick ascension, nausea, abdominal pain, headache, fever, etc. The right pulse is big and stressful. 4) Various symptoms related to digestive, respiratory, circulatory and reproductive system are represented by Sik-jeok. - Contemporarily women uterine or ovarian disease and back pain are mostly caused by Sik-jeok 5) Pediatric disease are mostly caused by Sik-jeok. 6) Treatment of Sik-jeok is light eating and if it is serious, you have to induce vomiting or diarrhea. Commonly used drugs are digestive medicine and invigorative medicine 7) To prevent Sik-jeok, you should forbid to eat until you are satisfied and wear warm clothes and continue to do spleen and genital do-in-beop.
