Modeling product configurations needs large amounts of knowledge about technical and marketing restrictions on the product. Previous attempts to automate product configurations concentrate on representations and management of the knowledge for specific domains in fixed and isolated computing environments. Since the knowledge about product configurations is subject to continuous change and hard to express, these attempts often failed to efficiently manage and exchange the knowledge in collaborative product development. In this paper, XML Topic Map (XTM) is introduced to represent and exchange the knowledge about product configurations in collaborative product development. A product configuration model based on XTM along with its merger and inference facilities enables configuration engineers In collaborative product development to manage and exchange their knowledge efficiently. An implementation of the proposed product configuration model is presented to demonstrate that the proposed approach enables enterprises to exchange the knowledge about product configurations during their collaborative product development.

According to the growing importance of science and technology policy, investment in research and development (R&D) has been increased. In this context, a patent as one of outcome of firm's systematic R&D investment is the way to hold a dominant position in companies' technology competitiveness and also to protect technology right. This study attempts to find the effects of input resources and intellectual property production activity on company value. It conducted empirical analysis based on 238 KOSDAQ-listed and medium-sized firms. Using the previous research, this study configurated research variables about activity of patent production, company value, and input of resources. Through these variables, it aims to know the effect of input of resources and activity of patent production on company value. First, the result of regression analysis shows that R&D cost has the positive effect on a patent production and sales promotion cost positively affects on the registration of the trademark. Second, the output of regression analysis indicates that a patent has the positive effect on company value but a trademark has not. With regard to the input of resources, R&D cost has the influence on company value but sales promotion cost has not. This study attempts to find the effectiveness of company's intellectual property registration on its value and suggests a way that the systematic R&D investment contributes the growth of company value.

The purpose of study is to provide efficient initial approaches for counseling in social work practice settings. First, it attempts to identify the correlation between the Myers-Brigg's Type Indicator(MBTI), a personality index based on the theory of psychological typology, and Personality Adaptation Types(PAT) models. Second, it attempts to develop a counseling method which can be applied to the initial interview, using the paradigm of door to therapy such as "Open Door", "Target Door", and "Trap Door" based on the PAT theory. The result of the quantitative study showed the correlation between MBTI and PAT as follows: MBTI Extrovert and Feeling(E, F) type was statistically correlated to hysterical PAT. MBTI Extrovert, Intuition and Perceiving(E, N, P) type was statistically correlated to Obsessive-Compulsive PAT. In conclusion, this study finds that when a clinical social worker approaches a client with the client's MBTI personality type and an interventional personality adaptation theory approach such as "Open Door", "Target Door", or "Trap Door", the efficiency of communication is increased significantly.

To the elderly, sudden falls are one of the most frightening accidents. If an accident occurs, a prompt action has to be taken to deal with the situation. Recently, there have been a number of attempts to detect sudden falls using acceleration sensors embedded in the mobile devices, such as smart phones and wrist-bands. However, using the sensor readings only, the detection rate of the falls is around 65%. Ordinary daily activities such as running or jumping could not be well distinguished from the falls. In this paper, we describe our attempts on improving the fall-detection rate. We implemented a wrist-band fall detection module, using a three-axis acceleration sensor. With the pattern matching on the fall signal-strength frequency spectrum, in addition to the conventional signal strength measurement, we could improve the detection rate by 9% point. Furthermore, by applying two wrist-bands in the experiment, we could further improve the detection rate to 82%.

Purpose: This study was conducted to investigate factors influencing suicidal ideation in people with mental disorder. Methods: The subjects were 176 people with mental disorder from community mental health centers, social rehabilitation facilities, and university hospital psychiatric outpatient departments. The instruments used included a suicidal ideation questionnaire, a self-esteem scale, a spiritual well-being scale, a family support scale, and a professional support scale. Data were analyzed with t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical regression analysis. Results: Suicidal ideation was influenced by age, history of suicidal attempts, and existential spiritual well-being. This study shows that suicidal ideation has negative correlation with existential spiritual well-being, self-esteem, family support, and age. Existential spiritual well-being, history of suicidal attempts, and age accounted for 30% regarding suicidal ideation in people with mental disorder. Conclusion: The lower existential spiritual well-being and age, the higher suicidal ideation. And also suicidal ideation was higher in people who had attempted suicide than in those who had not. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes existential spiritual well-being in order to decrease suicidal ideation in young people with mental disorder.

Objective : This paper attempts to analyze the curriculum of the modern Korean Medicine's higher education institutions and study their significance. Rather than conducting an in-depth pedagogical research, the paper attempts to summarize and provide a simple analysis on the subject matter due to the lack of the historical evidence of modern Korean Medicine. Method : General theses and academic papers along with daily publications before the Japanese colonial era, materials owned by Kyunghee University Korean Medicine History Museum, and history databases owned by the National Institute of Korean History and Kyujanggak were investigated Result : Upon studying the curriculum of Korean Medicine's higher education institutions, it could be concluded that the efforts to maintain the independence and professionalism of Korean Medicine in its relationship with the Western Medicine. It could also be discovered that the curriculum was improved through policy measures in order to raise the status of the practitioners and expand the scope of their practices. These higher education institutions has been continuously working to develop the Korean Medicine and raise the quality of curriculum, and their efforts were vital in the establishment of the Korean Medicine Doctor system. Conclusion : Systematic academic researches should be done on the curriculum of Korean Medicine's high education institutions in order to fulfill the objective of normalizing the Korean Medicine education and contributing to the growth of Korean Medicine.

In case of soil nailing system, there have been many attempts to expand into slope and temporary earth retaining system stabilization method since the first ground excavation earth retaining system construction in 1993. Recently, jointing wall, underground wall of buildings and excavation earth retaining wall, construction were increasingly applied for effective utilization of the limited underground space and land application maximized. However, the application of joining wall into retaining wall or building by temporary soil nailing system and design of permanent wall were performed by using Rankine earth pressure theory without considering the distribution of earth pressure in the soil nailing. In this study was performed to introduce the design case by 'Two-Body Translation mechanism (TBTM)' to be able to consider distribution of earth pressure in the soil nailing when designing the permanent jointing wall using soil nailing system for effective utilization of ground space. Also, this study attempts to evaluate the earth pressure change, decreasing effect of wall displacement and increasing effect of stability when advanced soil nailing system is constructed using $FLAC^{2D}$ ${\nu}er.$ 3.30 program and 'Two-Body Translation mechanism'.

This study attempts to investigate a general service sector model which aims to describe the extent to which customer repurchase intention is influenced by customer satisfaction, Customer loyalty, switching cost. This study attempts to investigate different group. Brand group 1 is higher Brand loyalty than Brand group 2. Brand Group 1 is 276 and Brand Group 2 is 271 consumers in service sector that they were used into data analysis. The data were analyzed by factor analysis and Structural Equation Model using SPSS and AMOS program. The results show that nearly all of the hypothesized relationships construct are supported. First, the direct effects of customer satisfaction on customer loyalty and switching cost were confirmed. The service company not only strengthens customer loyalty, but also strategically makes the most use of switching cost to satisfy customer satisfaction and create sustainable company advantages. Second, the interactive relationships among switching cost and customer loyalty were very significant. The proper management of these mediating variables plays key roles in connecting customer satisfaction with repurchase intention. Third, the effects of customer loyalty and brand preference on repurchase intention were supported but switching cost rejected in the path analysis. Implications of the results for path analysis are discussed and future research directions are offered.

The comtemporary architecture has not an discourse on form and representative style, but a new architectural concept of the generative process through the various relationship of the urban context, the continuity of the time and the experience of the people. This architectureal concepts make new and various architectural attempts to have a virtuality. The viruality is a reality to coexist with the present in contemporary philosophy. Daniel libeskind makes various arhcitectural experimentative attempts to reveal his virtuality through his memory as the Jews and his unconscious virtuality. The 'line' has the connotation of architectural reality and virtuality. Every line drawn becomes architectural form for example, walls, windows and makes spaces, and reveal a boundary as a connection. Architecture's visibility understates and structures its invisible aspect, so that the visible and the invisible make the architecture together. Daniel libeskind maks the virtual lines having the invisible of unconsious, time, and place. He no longer divide the form of architecture, its spatiality from all the implications which it adresses beyond its own particular built time and place and public unconsious mind. He demands the 'virtual line' that remembers distress and the past and reveal the virtuality of time and place. The virtual line is the sentimental communication of architecture.

In this paper, a comparative study of the effects of soil modelling on the interaction between tunnelling in soft soil and adjacent piled structure is presented. Several three-dimensional finite element analyses are performed to study the deformation of pile caps and piles as well as tunnel internal forces during the construction of an underground tunnel. The soil is modelled by two material models: the simple, yet approximate Mohr Coulomb (MC) yield criterion; and the complex, but reasonable hardening soil (HS) model with hyperbolic relation between stress and strain. For the former model, two different values of the soil stiffness modulus ($E_{50}$ or $E_{ur}$) as well as two profiles of stiffness variation with depth (constant and linearly increasing) were used in attempts to improve its prediction. As these four attempts did not succeed, a hybrid representation in which the hardening soil is used for soil located at the highly-strained zones while the Mohr Coulomb model is utilized elsewhere was investigated. This hybrid representation, which is a compromise between rigorous and simple solutions yielded results that compare well with those of the hardening soil model. The compared results include pile cap movements, pile deformation, and tunnel internal forces. Problem symmetry is utilized and, therefore, one symmetric half of the soil medium, the tunnel boring machine, the face pressure, the final tunnel lining, the pile caps, and the piles are modelled in several construction phases.
