The problems with the small exhibition buildings such a small gallery and art center recently constructed did not make the characteristics of the place specifying and did not form a big flow in the line of urban connection. Also it was deficient in the image like a cultural space because of the commercial aspects of the individual buildings. According to this view, this study is to evaluate the exteriors of the small exhibition buildings that the public prefers on the psychological side as a design theory and then, it is to present the direction of desirable form constitution hereafter. In the design of the small exhibition buildings exterior that the public must prefers, the principles and techniques of constitution that operate are the most initiative as follows. As for the principles of unity in the constitution of the small exhibition buildings exterior that the public prefers, Eigen Value is 7.573 and the explanatory force takes 21.637% at the top and it plays a leading role. In the comparison of the appearance, it shows that it is a factor with the largest specific gravity. The next factors were grouped in good order: the balance, ornamental technique, change, shipping technique, rhythm, harmony, symbolic technique, area technique and adding technique. As a result, in the design of the small exhibition buildings exterior, the architects have to constitute the principles of balance, change, rhythm and harmony by most of the unity and the symbolic technique and form technique by most of the ornamental techniques harmoniously and have to give Identity like exhibition buildings.

As prior studies indicate that chronic diseases are mainly attributed to health behavior, preventive health care rather than treatment for illness needs to improve health status. Since chronic conditions require long-term therapy, health care expenditures to treat chronic diseases have been substantial burden at national level. In this point of view, this study suggests that the health promotion program should be based on Knowledge Based System Using Data Mining Technique, we developed a predictive model for preventive healthcare management on diabetes mellitus. Generally, in the outbreak of diabetes mellitus there is a difference in lifestyle and the risk factors according to gender. So we developed a predictive model in accordance with gender difference and applied the Logistic Regression Model based on Data Mining process. The result of the study were as follow. The lift of the last predictive model was an average 2.23 times(male model : 2.13, female model 2.33) more improved than in the random model in upper 10% group. The health risk factors of diabetes mellitus are gender, age, a place of residence, blood pressure, glucose, smoking, drinking, exercise rate. On the basis of these factors, we suggest the program of the health promotion.

In case of wild fire, early detection of wild fire is the most important factor in minimizing the damages. In this paper, we suggest an effective system that detects wild fire using a panoramic image from a single camera with PAN/TILT head. This enables the system to detect the size and the location of the fire in the early stages. After converting RGB image input to color YCrCb image, the differential image is used to detect changes in movement of the smoke to determine the regions which may be prone to forest fire. Histogram analysis of fire flame is used to determine the possibility of fire in the predetermined regions. In addition, image matching and SURF were used to create the panoramic image. There are many advantages in this system. First of all, it is very economical because this system needs only a single camera and a monitor. Second, it shows the live image of wide view through panoramic image. Third, this system can reduce the quantity of saved data by storing panoramic images.

This paper focuses on gender studies with respect to language education for KFL(Korean as a foreign language) students. It also attempts to view the role of gender as exerting influence on language learning and teaching, and surveys KFL teachers' awareness of the role of gender in Korean language education. It is conceivable that teachers who are aware of differences between female and male will be able to take these into account in their teaching; in doing so they will be more effective in their teaching than if they were to teach in ignorance of these differences. The survey for the teachers' awareness of gender difference was conducted through teachers' discussion as the follow-up measure of the questionnaire. A few teachers do not have a clear idea about the importance of gender differences in language teaching, but the majority have cognizance of the matter. For this research, a questionnaire was administered to 71 subjects, consisting 37 intermediate KFL students and 34 advanced KFL students. The result of the questionnaire reveals that 50.4% subjects use their words and intonation without recognizing the gender difference, on the other hand, 49.6% subjects recognize the gender differences in Korean language use. The result should be adopted as a sociolinguistic factor for the contents of second language education.

Cigarette smoking is a well known risk factor for cardiovascular disease and has negative effects on blood lipid and lipoprotein . Some of the associations between smoking and chronic disease can be attributed to the less healthful lifestyles of smokers. A large body of epidemiologic evidence suggests inverse relationships between ischemic heart disease and plasma vitamin C and E concentrations . Smokers have lower plasma concentrations of these vitamins than do nonsmokers. Smokers therefore need antioxidant vitamin supplementation. The purpose of this study was to investigate the effect vitamin supplementation on plasma lipid patterns in smoking college men. 24subjects were divided into 3 groups of which were the vitamin C supplementation group (n=8), the vitamin E supplementation group(n=8) and the vitamin C+E supplementation group(n=8). The vitamin C supplementation group consumed 500mg of ascorbic acid, the vitamin E supplementation group consumed 200IU of D-$\alpha$-tocopherol, and the vitamin C+E supplementation group consumed 500mg of ascorbic acid+ 200IU of D-$\alpha$-tocopherol for 4 weeks. We examined the plasma lipid patterns before and after the vitamins were supplemented. The results obtained were as follows ; In the vitamin C supplementation group, the concentration of total cholesterol decreased significantly and HDL-cholesterol increased significantly with the supplementation of vitamin. In the vitamin E and vitamin C+E supplementation groups, however, there were no significant differences observed with the supplementation of vitamin. Concentration of plasma LDL, triglyceride, free fatty acid were not significantly affected by the supplementation of vitamin in all groups. In terms of plasma fatty acid composition, the concentrations of saturated fatty acid were not significantly affected by the supplementation of vitamin in all groups. The concentrations of palmitoleic acid, arachidonic acid, and docosahexaenoic acid, however, significantly increased in the vitamin E supplementation group(p<0.05). The concentration of plasma linoleic acid significantly increased in the vitamin C+ E supplementation group)(p<0.05). The results of this study show that antioxidant vitamin supplementation in smokers has a tendency to decrease coronary heart disease risk in view of the plasma total cholestrol and HDL-cholesterol concentrations of the vitamin C supplementation group and fatty acid concentration of the vitamin E supplementation group.

Recently the Korean government's green energy growth policy has been taken at the national level due to the sufficient supply of renewable energy. Some specific technique should be taken in consideration for the operation of the grid voltage and power quality management. In this case, there may have some chance of operational problems. Typical problems arise when grid-connected solar power produced by Pacific sunshine. The power flow in the reverse direction can create overvoltage on the distribution line and gives value of malfunction on the system. Line voltage and overvoltage adjustment practice can stop these symptoms occurred. Under these circumstances, this paper presents an interconnection test devices for photovoltaic(PV) systems composed of distribution system simulator, PV system simulator and control and monitoring systems using the LabVIEW S/W, and simulates the customer voltage characteristics considering the 3 parameters on the introduction capacity for PV systems, system configuration and Power factor. This paper also proposes a new calculation algorithm for voltage profile to make comparison between calculation values and test device values. The results show that the simulation results for the normal operation characteristics of PV systems which are very practical and effective.

Aim: The risk factors mostly strongly associated with gastric cancer are gastric bacteria Helicobacter pylori and diet. Using a case-control study among residents in Jinan, we examined the association between the salt taste and gastric cancer according to H. pylori infection, smoking and histological type as well as tumor site. Methods: This population-based case-control study included 207 cases and 410 controls. Data on potential risk factors of gastric cancer were obtained by interview of cases and controls with a questionnaire, salt taste preference was measured for all subjects, and IgG antibodies to H. pylori were applied to assess infection. Risk measures were determined using unconditional logistic regression. Results: The proportions of salt taste at intervals of 1.8-7.2 g/L and ${\geq}7.2$ g/L were significantly higher in cases than controls, with ORs of 1.56 (1.23-3.64) and 2.03 (2.12-4.11), respectively, subjects with high salt intake having an elevated risk for gastric cancer when infected with H. pylori. Significant modification by smoking and tumor site was observed across the different measures of salt intake, the highest salt taste showed higher cancer risk in ever smokers or with non-cardia cancers. Conclusion: Our study supports the view that high intake of sodium is an important dietary risk factor for gastric cancer, with a synergistic effect found between salt and H.pylori and smoking, dependent on the tumor site.

In order to thoroughly analyze risk factors of breast cancer (BC) in premenopausal Uruguayan women, a case-control study was carried out at the Pereira Rossell Women's Hospital, Montevideo, where 253 incident BC cases and 497 frequency-matched healthy controls were interviewed on menstrual and reproductive story, were administered a short food frequency questionnaire and undertook a series of body measurements necessary to calculate body composition and somatotype. Odds ratio (OR) coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Among the classical risk factors, only the family history of BC in first degree relatives was significantly associated with risk of premenopausal BC (OR=2.20, 95% CI 1.33-3.62). Interestingly, this risk factor was found to be stronger in women of ages >40 (OR=4.05, 95% CI 2.10-7.81), late menarche (OR= 2.39, 95% CI 1.18-4.85), early age for their first delivery (OR=3.02, 95% CI 1.26-7.22), short time between menarche and first delivery (OR=3.22, 95% CI 1.29-8.07), and with high parity (OR=4.10, 95% CI 1.79-9.36), although heterogeneity was detected only for age and parity. High consumption of red meat was positively associated with the disease risk (OR=2.20, 95% CI 1.35-3.60), in the same way as fried foods (OR=1.79, 95% CI 1.12-2.84). Conversely, a high intake of plant foods displayed a protective effect (OR=0.41, 95% CI 0.26-0.65). Except for hypertension (OR=1.55, 95% CI 1.03-2.35), none of the analyzed components of metabolic syndrome were associated to BC risk. Particular increases of risk for premenopausal BC were found for family history in first degree relatives in certain subsets derived from the menstrual-reproductive history. Preventive strategies could broaden their scope if new studies confirm the present results, in view of the limited prevention measures that premenopausal BC currently has.

The competition for attracting outstanding HRST (human resource for science and technology) who can lead technological innovation is heating up all over the world. The various concepts, which are brain drain, brain gain, brain overflow, brain migration, brain circulation, are used to explain the international mobility of HRST. But the concept of brain scout is the more adequate for explaining in the case of outstanding HRST as the main cause of excessive competition for scouting. This study analyzed the critical factors of the determinants of Korean students in the USA who have intentions of returning to Korea in view of brain scout. As the first step in this study, potential factors and hypothesis are established by the interviews. As the second step, the major factors are examined by surveys and hypothesis testing. Also, a new model for decision-making is proposed which describes intentions of returning to Korea by logistic regression analysis and contributions of each factor derived from this study were compared. Finally, policy implications for attracting outstanding HRST and the limit of this study are discussed.

As increasing interests for cultural content, 3D restoration about the valuable traditional architectures is in progress, nowadays. Digital restoration is generally performed with using new IT technology and equipments such as 3D scanner. From the view points of making better use of the 3D data, the methodology for 3D restoration leaves much room for improvement. When using 3D scanner, it is possible to get precise 3D data for exterior of the building but huge data size and insufficient information for the wooden intra structure might be obstacles for using them as a source of various digital contents. In traditional wooden structure, the binding rules for corresponding architectural components are important factor for realizing the architectural culture at that times. In this paper, we develop a design tool and architectural components reflecting the wooden intra structure. Moreover, we propose a new 3D restoration method from the design tool, which is good for making contents offering useful information for processes of construction and binding rule in a real time just at a glance.
