We investigated the tracking and erosion resistance of the silicone rubber by Inclined-Plane Method. And. with the variation of experiment time, the chance of the leakage current waveform was evaluated. The typical leakage current waveform was the form of mixture of sinusoidal wave and rectifying wave. It is thought that the sinusoidal wave is due to conductivity of contaminant when wet. and the rectifying wave is due to arc of dry band.

Objective : To investigate the actual driving state of the stroke patients who had assessed CPAD. Methods : We conducted a follow-up survey with 48 stroke patients who had assessed CPAD. First, we reviewed the medical chart and then carried out the telephone survey. Results : Of the 48 subjects, 12 were driving and 36 were not driving. Current drivers' CPAD score, it was 54.13, was higher than non-drivers' CPAD score(p<0.05). Those who passed the CPAD were driving more than who failed(OR=8.3, 95%CI=1.931-35.558). Conclusion : The pass group of CPAD have higher chance of driving than fail group and have lower chance of car accidence than fail group. Thus we can apply the CPAD for driving cognitive evaluation tests.

Control Chart is a graph which dots the characteristic values of a process. It is the tool of statistical technique to keep a process in controlled condition. It is also used for investigating the state of a process. Therefore many companies have used Control Chart as the tool of statistical process control (SPC). Products from a production process represent accidental dispersion values around a certain reference value. Fluctuations cause of quality dispersion is classified as a chance cause and a assignable cause. Chance cause refers unmanageable practical cause such as operator proficiency differences, differences in work environment, etc. Assignable cause refers manageable cause which is possible to take actions to remove such as operator inattention, error of production equipment, etc. Traditionally ${\bar{x}}-R$ control chart or ${\bar{x}}-s$ control chart is used to find and remove the error cause. Traditional control chart is to determine whether the measured data are in control or not, and lets us to take action. On the other hand, RNELCC (Reflected Normal Expected Loss Control Chart) is a control chart which, even in controlled state, indicates the information of economic loss if a product is in inconsistent state with process target value. However, contaminated process can cause control line sensitive and cause problems with the detection capabilities of chart. Many studies on robust estimation using trimmed parameters have been conducted. We suggest robust RNELCC which used the idea of trimmed parameters with RNEL control chart. And we demonstrate effectiveness of new control chart by comparing with ARL value among traditional control chart, RNELCC and robust RNELCC.

Carol Christian Poell is a designer famous for experimental designs and presentations. Poell's actions in the fashion-world resemble Fluxus, an anti-art group that started working in the 1950s. This study analyzed the works of Poell based on the characteristics of Fluxus and then compared the works of Poell with the performance of Nam June Paik, a Fluxus artist. We conducted literature studies and case studies. We examined the works of Poell and Paik based on the four characteristics of Fluxus: iconoclasm, unity of art and life, playfulness and chance. The results were as follows. First, they were engaged in anti-aesthetic works. While Paik concentrated on the content aspect of works, Poell was more focused on formal aspects. Second, neither of them distinguished between art and life. Paik achieved it by including audiences in his works; however, Poell attained it by adopting daily spaces as a place to display presentations and use ready-made forms. Third, they showed playfulness with a satirical nuance. Paik expressed it in an erotic way; however, Poell implied it through the irrational settings of circumstance. Finally, they created works by utilizing chance. Paik focused on auditory elements and the content aspects of works; however, Poell used the coincidence of visual and tactile elements when creating his works. This study compared the works of Poell with Paik and has its significance in its usefulness to understand designers with Fluxus characteristics in the fashion industry.

Effective storage in agricultural reservoir has been determined through the reservoir simulation operation based on the water budget analysis. Since each watershed has the native property for runoff, considering the runoff yielding from the basin is feasible to the determination of reservoir effective storage. In this study the stochastic linear programming model considering mainly runoff from watershed has been also formulated to analyze the effective storage of the exiting reservoir. The linear decision rule coupled with chance-constrained model in the linear programming model contributes to reduce the size of linear program model without considering the period of analysis. The Geum-Gang reservoir located in Ansung have been adopted to evaluate the effective storage. It has been shown that the effective storage based on the linear programming model is greater than that based on the water budget analysis. It has been also desired that once the effective storage is obtained through the linear programming model, operation of the reservoir should be performed to check the designed capacity.

Flux, essentially used in soldering process of PCB (Printed Circuit Board) in electronics industry, contains IPA (Isopropyl alcohol) and methanol, which are highly inflammable and explosive. Hazard Chemical Controlling Law classified methanol as toxic material and Environmental Law classified methanol as VOC (Volatile Organic Compound). So there have been pressing needs of developing substitutes for the existing Flux. New solvent which is non-flammable and main component is DCP having same specific character of the existing Flux. It's been combirated with proper composition ratio adding stabilizer. As a result, it relieved working Environment Allowance thickness 200 ppm to 470 ppm, chance of not been soldered 0.083% to 0%, spread 85% to 87%, power saving resistance 1.0$\times$$10^{12}$$\Omega$ to 6.9$\times$$10^{12}$$\Omega$, which means a lot better than the existing Flux. Therefore, Flux confirmed the chance of improving productivity, safety, environment safety and quality. Also, Flux got a satisfied result after product quality test and product reliability test.

This study is a report about the two summer camps of 2009 and 2010, which were held by some gifted classes of Liberal Arts areas in Chungnam Province. The students' self- directed methods, making an own project topic and an outline plan for that by students themselves before the camp, raised up the students' satisfaction of the camp effectively. Staying with their peer students and teachers for 3 days gave the gifted students a chance for relationship, self-confidence, and self-sufficiency. These joint summer camps provided the students with cognitive development, motivations and a chance to meet other gifted students. Teachers' preparation for the camp, their concrete feedback to each student's project, and students' time spending on one's own camp project were correlated with the students' satisfaction of the camp program. Experience of teacher training in gifted education made significant differences in understanding gifted students and expectations of students' social and emotional development throughout and after the camp.

FDI World Dental Federation is organization representing more than one million dentists worldwide with its more than 100 years of long history. Now FDI headquarter is located in Geneve, Switzerland and serves for developing health policy and continuing education programs, speaking as a unified voice for dentistry in international advocacy and supporting member association in oral health promotion activities worldwide. Korean Dental Association has been a member of FDI since 1959 and participated actively in the FDI's worldwide activities. Past Dr. Heung-Ryul Yoon was a president of FDI from 2003 for 2 years and we also have an experience in 1997 of hosting FDI Annual World Dental Congress successively in Seoul. The image of a country reflects the country's culture as well as affects to its economical and social development and it decides the national brand toward the world. Currently, Korean people realized that and put their efforts for promoting diverse aspects of Korea to the world such as multimedia culture called Han-Ryu, electric industry, automotive industry, sports represented by soccer. We have advanced technique and skill in various fields and now it's time to show ourself better to the world. It's same to the dentistry. It's true that Korean dentistry is top-class in the world and the dental industry is prosperous and also has best technique in the world. I think and strongly hope that the 2013 FDI Seoul Annual World Dental Congress would be best opportunity for Korean dentistry and dental industry to promote ourselves and make a big step to the world. Not only for the dentistry, it will also be very good chance to all the Korean people to improve Korean national brand. I believe that we can accomplish if we, all dental societies, stand together and join our effort to use this good chance the best. I know we can make it.

This study was to investigated the relationship between health locus of control and health promoting behavior of College students. For this study, questionnaires were given to 300 students in the H University of Seoul and collected during the period from Nomber 17 to November 24, 1994. Health locus of control and health promoting behavior were measured by using the MHLC scale and a modified HPLP scale. Healthiness of life style is parameterized by self actualization, health responsibility, exercise, nutrition, stress management, and internal support. The data were analyzed using the statistics package SAS, yielding frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's Correlation. The result of this analysis are as follows: 1. Among the components of health locus of control, internal health locus of control showed the highestscore (mean: 3. 12, standard deviation: 0.46). Powerful others health locus of control followed next with the mean of 2. 30 and the standard deviation of 0.44. Chance health locus of control showed the mean of 2.29, and the standard deviation of 0.43 2. The HPLP mean score and the standard deviation of practice of health promoting behavior were 2.51 and 0.31 respectively. 3. HPLP correlated positively with internal health locus of control (r= 0.20, p<.01) and powerful others locus of control (r= 0.21. p<.001). However, HPLP inversely correlated with chance locus of control (r=-0.13, p<.05) 4. The demographic variables representing sex (t= 2.26, p<.05), health status (F = 5.52, p<.01) showed connections to health promoting behavior. Therefore, nurses should consider health locus of control when they take care of College students to improve such health promoting behavior as self actualization, exercise, internal support, stress management, and health responsibility. Further research is required to discover factors influencing health promoting behavior of College students.
