Recently, Korean society is increaseing "1 person family" phenomenon, which is influenced by changing of young peoples' value, aging society and social economic problems. Increase of single households is a result of complex economic, cultural and social factors. It is because as the individual's financial independence increases due to elevated income and education level, the age of marriage is going up and the individualism, which values the individual's value rather than custom, is spreading. Therefore, this new phenomenon will be impact to between social, economic value structure and living space. An increase with small furnitures are also increasing of R&D and marketing plans for 1 person family. Currently, 1 person family is bigger than last decade and that is requiring more suitable and multi-functional furniture for them. However, in Korea furniture companies are more optimization to traditional family size. Thus, this research explore about developing cheap price sofa bed, which is using at narrow area and small place.

These days mobile phone which were used mainly by grown-up persons are now widely used among children as well due to new social demands. Despite this trend, existing mobile phones are still being designed and produced according to the taste of people in their 20s and 30s, even the elderly, not satisfying physical, emotional and cognitive characteristics raised by children. This study aimed to extract the design factors of mobile phones for children by reflecting functional factors requested by children and parents in QFD's customer demands. First, functional and design factors requested in mobile phones for children were extracted from existing products and documentary records and some functional factors were selected through a process of integration and omission. The survey research was conducted on children and parents, based on the selected functional factors. Based on the survey research, functional factors were analyzed using AHP, and key functional factors considered by children and parents in mobile phones for children were investigated. Finally, in order to reflect the results in QFD, the correlation between functional factors and design factors was constructed as HOQ through experts' evaluation. The results showed that both children and parents recognized the basic functions such as telephoning, text messaging and phone directory as high priority functional factors, even though the relative importance was different between children and parents. Therefore, it is likely to satisfy the desires of both children and parents by designing mobile phones for children in consideration of design factors such as menu depth, button independence and button arrangement. It is expected that this study will promote experiments on design factors and propose basic data for and guidelines to mobile phone design for children.

The component-based development methodology becomes famous as the new way for reuse. The goal of the reuse is improvement of quality, productivity and independence on the software development. For the improvement in the quality of a component-based system, it is necessary to research component metrics in the early phase of a component development. Hence, in this paper, we propose new component metrics using the information of a component analysis phase. Those are CCI(Complexity of Component Interface) and LCC(Lack Cohesion of Component interface). CCI indicates a difficulty about comprehension, modification, management, use of interface. LCC indicates a functional independence about how strong the elements are related with. Therefore, it is possible to predict and manage the quality of a component to be developed. Predicting a lowness of complexity and highness of cohesion as an independent functional unit by a component interface in the early phase of a component development, we can expect the improvement in the quality of a system.

In this paper the independence axiom, one of two principal axioms of axiomatic design theory, is applied to the leveling system development as an design criteria. After functional requirements and corresponding design parameters constitute an initial design matrix for the leveling system, sequence, which is compatible with the independence axiom, of the design parameters of the design matrix is determined and independent components of block leveling system are revealed. As a result of axiomatic design, system configuration related to the design sequence is developed. In order to verify and validate the developed block leveling system, test with real hull block leveling work in site by using total station which is used to acquire three dimensional coordinate of target point is performed. Comparison with measured data and output data from the block leveling system shows the system accuracy is under 1 mm so that the developed system is verified and validated to be used in site.

The aim of this study was to investigate the effects of Client-centered mental practice on activities of daily living and quality of life with stroke. For 16 persons with stroke, we executed Client-centered mental practice for 4 weeks, five times per week, and 30 minutes each time. Before and after the Client-centered mental practice, the patients were tested with Functional Independence Measure(FIM) and Stroke specific quality of life(SS-QOL). After the Client-centered mental practice, the subjects showed significant changes in the score of FIM and SS-QOL(p<0.05). The results of this study show that Client-centered mental practice for persons with stroke is a useful therapeutic approach by enhancing through improving their activities of daily living and quality of life.

This study compared and analyzed existing studies and released papers to identify the "definition and scope of urban agriculture" which correspond to the circumstances of Korea based on the fact that urban agriculture was selected as one of the measures to pursue green growth by the Presidential Committee on Green Growth (PCGG) and the discussions and deliberations among PCGG, government, academia, civic organizations, and experts. It also aims to present the ways of policy to facilitate the development of urban agriculture based on the mentioned identification. This research proposes the definition of urban agriculture as 'all agricultural activities that incorporates multi-functional public benefits of agriculture performed within the administrative district of a city. However, the scope of urban agriculture should exclude the agricultural sites, the methods, and the activities that are against the multi-functional public benefits of agriculture, which will be determined depending on the spaces, methods, and purposes of planting food crops. In order to facilitate the development of urban agriculture, the government should implement the policy measures as following: (1) to analyze spaces for farming, and provide the spaces to the citizens; (2) to prepare legislation and institution that will allow citizens to use the farming spaces continuously; (3) to develop Korean-style urban agriculture model that fully reflects the features of Korean cities; (4) to develop a system where the urban citizens can easily learn and experience the urban agriculture; and, (5) to provide incentives that will attract active participation of urban citizens such as carbon mileage. (6) to analyze effect of urban agriculture to save energy and food self-sufficiency.

Purpose: This study was done to examine the effect of an integrated care service which included a combination of oriental and western care on health outcomes in elderly patients with degenerative arthritis. Methods: A prospective comparative design was used. Data were collected from May 1, 2008 to June 30, 2009 from 85 elderly patients with degenerative arthritis in the lower extremities who were followed in a hospital out-patient department for 8 weeks. The integrated care service group (n=36) received a combination of physical therapy, acupuncture, western medicines or herbal medicines, and the western care group (n=49) received physical therapy or western medicines. Functional independence, walking speed, rotation balance, pain intensity, service satisfaction and total medical costs for the two groups were compared at 8 weeks. Results: Functional independence (t=2.14, p=.036) and walking speed (t=2.51, p=.014) improved significantly in the integrated care group while pain intensity improved significantly in the western care group (t=3.35, p=.002). The integrated care group reported higher scores for service satisfaction (t=2.09, p=.041) and higher medical costs than the western care group (t=2.15, p=.035). Conclusion: The results suggest that integrated care services are effective modalities to improve mobility and quality of life for elders with degenerative arthritis.

The purpose of this study was to investigate psychological separation, depression and antidepressive coping behaviors and to examine the relationship between psychological separation, and depression in Korean university students. The subjects were 131 students who were in 4 university in Chungcheong-do, Korea. The data were collected through self reported structured questionnaire using the psychological separation index, beck depression inventory and antidepressive coping behaviors instrument. The level of depression was classified into; not depressed, 54.2%; mildly depressed, 22.9%; moderately depressed, 16.8%; severely depressed, 6.1%. Among antidepressive coping behaviors, cognitive activity-oriented behaviors was the one with highest percentage(30.8%). Depression was negatively related to functional independence, attitudinal independence, emotional independence from father and conflictual independence from mother. And depression was positively related to conflictual independence from father. These results suggest that it is necessary to develop nursing intervention to strengthen psychological separation form parents and to be able to help desirable antidepressive coping behaviors for the psychological health of university students.

In product design and manufacturing, axiomatic design provides a systematic approach for the decision-making process. Two axioms have been defined such as the Independence Axiom and the Information Axiom. The Information Axiom states that the best design among those that satisfy the independence axiom is the one with the least information content. In other words, the best design is the one that has the highest probability of success. On the other hand, the Taguchi robust design is used in the two-step process; one is "reduce variability," and the other is "adjust the mean on the target." The two-step can be interpreted as a problem that has two FRs (functional requirements). Therefore, the Taguchi method should be used based on the satisfaction of the Independence Axiom. Common aspects exist between the Taguchi method and Axiomatic Design in that a robust design is induced. However, different characteristics are found as well. The Taguchi method does not have the design range, and the probability of success may not be enough to express robustness. Our purpose is to find the one that has the highest probability of success and the smallest variation. A new index is proposed to satisfy these conditions. The index is defined by multiplication of the robustness weight function and the probability density function. The robustness weight function has the maximum at the target value and zero at the boundary of the design range. The validity of the index is proved through various examples.gh various examples.
