This study examined human rights perception, cultural diversity perception, level of character perception, and influencing factors for university students in order to prepare basic data on integrated education methods of character, human rights and cultural diversity and education program models. The research questions are as follows. 1. What are university students' perceptions of character, cultural diversity and human rights? 2. What is the status of the experience of family life education on character, cultural diversity, and human rights, and is it related to the level of perception? 3. What variables affect character perception, cultural diversity perception, and human rights perception? The survey targeted 407 students at two universities in Seoul and used IBM PASW Statistics as a tool to analyze data. The study results are as follows. First, university students' character, cultural diversity and human rights perception were above average; however, empirical education is still required because they had low scores in the area of action. Second, male university students have less experience in family life education on character, cultural diversity and human rights compared to female university students. Third, it is necessary to integrate education for character, cultural diversity and human rights because the most influential factors in character perception, cultural diversity perception and human rights perception were character education. The role of family life education should be considered important because personality education in the home showed a relatively high correlation.

A reduction of the response of irregular structures subjected to earthquake excitation by control devices equipped by suitable control algorithm is proposed in this paper. The control algorithm, which is used, is the pole placement one. A requirement of successful application of pole placement algorithm is a definition-selection of suitable poles (eigen-values) of controlled irregular structures. Based on these poles, the required action is calculated and applied to the irregular structure by means of control devices. The selection of poles of controlled irregular structure, is a critical issue for the success of the algorithm. The calculation of suitable poles of controlled irregular structure is proposed herein by the following procedure: a fictitious symmetrical structure is considered from the irregular structure, adding vertical elements, such as columns or shear walls, at any location where is necessary. Then, the eigen-values of symmetrical structure are calculated, and are forced to be the poles of irregular controlled structure. Based on these poles and additional damping, the new poles of the controlled irregular structure are calculated. By pole placement algorithm, the feedback matrix is obtained. Using this feedback matrix, control forces are calculated at any time during the earthquake, and are applied to the irregular structure by the control devices. This procedure results in making the controlled irregular structure to behave like a symmetrical one. This control strategy can be applied to one storey or to multi-storey irregular buildings. Furthermore, the numerical results were shown that with small amount of control force, a sufficient reduction of the response of irregular buildings is achieved.

While extensive efforts have been made in the past to develop finite element models (FEMs) for concrete-filled steel tubular columns (CFSTCs), these models may not be suitable to be used in some cases, especially in view of the utilisation of high strength steel and high strength concrete. A method is presented herein to predict the complete stress-strain curve of concrete subjected to tri-axial compressive stresses caused by axial load coupled with lateral pressure due to the confinement action in square and rectangular CFSTCs with normal and high strength materials. To evaluate the lateral pressure exerted on the concrete in square and rectangular shaped columns, an accurately developed FEM which incorporates the effects of initial local imperfections and residual stresses using the commercial program ABAQUS is adopted. Subsequently, an extensive parametric study is conducted herein to propose an empirical equation for the maximum average lateral pressure, which depends on the material and geometric properties of the columns. The analysis parameters include the concrete compressive strength ($f^{\prime}_c=20-110N/mm^2$), steel yield strength ($f_y=220-850N/mm^2$), width-to-thickness (B/t) ratios in the range of 15-52, as well as the length-to-width (L/B) ratios in the range of 2-4. The predictions of the behaviour, ultimate axial strengths, and failure modes are compared with the available experimental results to verify the accuracy of the models developed. Furthermore, a design model is proposed for short square and rectangular CFSTCs. Additionally, comparisons with the prediction of axial load capacity by using the proposed design model, Australian Standard and Eurocode 4 code provisions for box composite columns are carried out.

Double skin composite walls are increasingly popular and have been applied to many safety-related facilities. They come from the concept of composite slabs. Conventional connectors such as shear studs and binding bars were used in previous studies to act as the internal mechanical connectors to lock the external steel faceplates to the concrete core. However, the restraint effects of these connectors were sometimes not strong enough. In this research, a recently proposed unique type of steel truss was employed along the wall height to enhance the composite action between the two materials. Concrete-filled tube columns were used as the boundary elements. Due to the existence of boundary columns, the restraints of steel faceplates to the concrete differ significantly for the walls with different widths. Therefore, there is a need to explore the effect of height-to-width ratio on the structural behavior of the wall. In the test program, three specimens were designed with the height of 3000 mm, the thickness of 150 mm, and different widths, to simulate the real walls in practice. Axial compression was applied by two actuators on the tested walls. The axial behavior of the walls was evaluated based on the analysis of test results. The influences of height-to-width ratio on structural performance were evaluated. Finally, discussion was made on code-based design.

Background: Cancer is a primary source of concern in Thailand and other countries around the world, including the Asian-Pacific region. Evidence supports that an important contributing cause of cancer and other chronic illnesses such as stroke, diabetes, and hypertension is excessive alcohol consumption. Studies conducted in Thailand reveal a worrisome rise in the number of new and regular drinkers in communities. Therefore, actions for primary, secondary and tertiary prevention of problem drinking are necessary. In recent years nurses in North East Thailand have been developing and implementing the Khon Kaen Family Health Nursing model to embed disease prevention in communities through the actions of family health nurses and local family health leaders. Aim: The aim of this qualitative research was to better understand the experiences of the local family health leaders using this model and to synthesize lessons learned. Materials and Methods: As part of a participatory action research approach involving analysis of focus group discussions and individual interviews, the experiences of 45 family health leaders were synthesized. Results: Four main themes were identified, namely: i) Family first: role modeling beginning at the personal and family level. ii) Local leverage: using village community forums to reduce alcohol drinking. iii) Gentle growth: making the first step and treading gently; and iv) Respect, Redemption, Rehabilitation: valuing the person to re-integrate them in the village society. Conclusions: As alcohol consumption in the village declined significantly following the prevention program, these findings illuminate how low-tech integrated prevention approaches may be very useful, particularly in rural communities. The lessons learned may have relevance not only in Thailand but in other countries seeking to prevent and mitigate behavior that conduces to diseases such as cancer.

Purpose: The purpose of this study was to investigate the stages of change in smoking cessation after a Coronary Artery Bypass Graft(CABG) and to identify the related factors. Methods: The subjects (n=157) were patients who underwent a CABG in a university hospital from March 1998 to October 2005 and were smokers before the CABG. Data was collected viachart review and a telephone interview, and analyzed with descriptive statistics, $X^2$ test, one-way ANOVA, and Kruskal-Wallis procedure by the SPSS/PC win 12.0 program. Results: The subjects smoked for an average of 34 years (21 cigarettes per day) before surgery. Eleven percent of the subjects were in pre-contemplation, 6.4% in contemplation, 13.5% in preparation, 4.5% in action, and 64.5% in the maintenance stage. Nicotine dependence and self-efficacy were different among the groups with different stages of change in smoking cessation. Nicotine dependence was the lowest (p=0.00) and self-efficacy was the highest (p=0.00) in the maintenance stage. The number of subjects in pre-contemplation and contemplation significantly increased 6 years after surgery(p=0.05). Conclusions: To implement effective smoking cessation interventions for CABG patients, the intervention should be developed to accommodate individual readiness for smoking cessation, especially so for those who had a CABG more than 6 years previously.

This study aims to suggest the ways to reinforce academic library's research support services for professors and researchers in Korea. For this purpose, this study collected the development plans of academic libraries in Korea, and analysed the plans for supporting research activities, and also analysed each library's homepage. And this research classified the research support services of academic libraries into eight types for further analysis. The types are 'subject guide', 'academic information literacy', 'research analysis service', 'research consulting', 'research ethics education', 'thesis writing guide', 'bibliography management program', 'interlibrary loan·original text copy'. As a result, it is shown that the most libraries emphasized 'custom-tailored user education' and marked it on development plan. As subsequent plans, libraries provided the action plans of 'expansion of scholarly DB instruction on each subject', 'expansion of custom-tailored research support services', 'construction of research support service system' one after another. This study suggests 'activation of subject guide service', 'expansion of academic information literacy programs for supporting research', 'introduction of research performance analysis services', and 'support for establishment of research ethics' as ways to strengthen academic libraries' research support services.

Ever more so than any other times, today's corporations today face an ultimate issue of acquiring highest work expertise for their employees. However, most of current academic researches try to focus on what factors comprise an expertise while they fail to tackle the very issue of detailed numerical measurement of the expertise factors recommended improvement paths, and goals for each measured expertise level. Hence, this study suggests more objective and highly reliable identification of work competence measurement factors and the correlation among the identified factors. For details, it tries to propose a methodology of expertise measurement by developing into the definition of experts and expertise, reestablishment of expertise factors, determination of reference points of the expertise factors, and weighting of the factors. This measurement methodology finds that it itself has significant correlation with existing work competency level measurement and test tools. Therefore it is identified to justify its effectiveness. Finally, this study proposes an action point of establishing a national expertise architecture and its frameworks for various societies in general.

This study shows that clothes to be just the same as the real thing can be Produced through the third dimension computer graphics, and then presents that not only the area of fashion design can be expanded in the virtual reality field by doing the simulation of the fashion show, but also the information can be made the real time public ownership and the communication can be fulfilled smoothly. In this study, analyzing the third dimension computer graphic programs to be used much at present, Alias Wavefront Company's Maya software which was the most effective in the clothes simulation and the clothes CAD SGS OptiTex 8.7 which went well substitutive for it were used of them. The conclusions of this study that got through the work manufacture are as follows： The first, if the file manufacturing in the clothes CAD by using the computer was stored, the pattern used 3D simulation was available because it could be summoned in 3D software. The second, if the data of DXF form in Maya program was summoned, they could not be applied by Maya Cloth supported in Nurbs only because they were recognized as the DXF＿layer. So the curve along the outer lines of the pattern was drawn and Maya Cloth was applied to be possible to get the natural silhouette of clothes. The third, when the clothes were manufactured by 3D, if the draping character was applied according to the textile special quality, not only the control of textile's thickness, weight, quality feeling, and silhouette was available, but also the clothes were available to graft the special textile materials. The fourth, the natural motion of model was produced by capturing the actual model's walking action In order to produce the fashion show motion and also the dynamic fashion show was available by the angle of camera, the establishment of lighting, and etc. in the final rendering. The clothes manufactured by 3D are available to change the design by changing the materials, or by adding the details, or by utilizing the special materials on clothes. Therefore, the trial and error following at the clothes manufacture can be reduced. But the elevation of the rendering speed, the price down, the strengthening of personal security, and etc. are required.

To prevent the use of one's smartphone by another user, the authentication checks the owner in several ways. However, whenever the owner does use his/her smartphone, this authentication requires an unnecessary action, and sometimes he/she finally decides not to use an authentication method. This can cause a fatal problem in the smartphone's security. We propose a sustainable android platform-based authentication mode to solve this security issue and to facilitate secure authentication. In the proposed model, a smartphone identifies the current situation and then performs the authentication. In order to define the risk of the situation, we conducted a survey and analyzed the survey results by age, location, behavior, etc. Finally, a demonstration program was implemented to show the relationship between risk and security authentication methods.
