This study applied an exploratory analysis based on Self Organizing Map and GIS to cause specific age-standardized regional death rates data related to ten types of male cancers to find meaning patterns in the data. Then the patterns revealed from the exploratory analysis was evaluated to investigate possible relationship between these patterns and regional socio-economic status represented by regional educational attainment levels of head of household. The results from this analysis show that SI-GUN-GUs in Korea can be clustered to eighteen unique clusters in the stand point of male cancer death rates and these clusters are also spatially clustered. Also, the results reveal that regions with higher socio-economic status show lower level of the death rates compared with the regions with lower socio-economic status. However, for some cancer types, the regions with higher socio-economic status show relatively higher death rates. These patterns imply that the prevention, detection, and treatment of male cancers might be strongly affected by regional factors such as socio-economic status, environmental factors, and cultures and norms in Korea. Especially, one of the eighteen clusters, which includes Gangnam-Gu and Seocho-Gu, shows lower death rates in many of male cancer types. This implies that socio-economic status may be one of the most influential factors for regional cancer control.

Purpose: This article attempted to examine how teeth for restoration is made in a clinical practice and utilize it as future educational material of teeth formation and basic data for additional research. Materials and methods: This experiment investigated the models sent to milling center for production of zirconia crowns. After scanned with Lava CAD/CAM System (3M ESPE, Seefeld, Germany), they are measured on 'ImageJ (version 1.32j, National Institutes of Health, USA)' program and compared and analyzed. Convergence angle from mesio-distal surfaces and bucco-lingual surfaces of each teeth are measured. Also, bucco-lingual diameter of the region lowered as much as 0.4 mm from incisal edge in anterior teeth except canines.(This measure is defined as the Peak 0.4) The analysis of data between each group was conducted by Windows SPSS statistic program, and was proved significant on 95% confidence level by independent t-test, one-way ANOVA and multiple analysis (Sheff${\'{e}}$ test). Results: The mean value of convergence angle was $18.67^{\circ}$ It is ranked as molar ($26.70^{\circ}$) > premolar ($16.87^{\circ}$) > anterior teeth ($14.81^{\circ}$) in the order of mesio-distal convergence angle; anterior teeth ($22.32^{\circ}$) > molar ($20.93^{\circ}$) > premolar ($15.41^{\circ}$) in the order of bucco-lingual convergence angle. The mean value of Peak 0.4 was 1.18 mm. Conclusion: Convergence angle of abutment of zirconia all ceramic crown has difference depending on the location in the arch. Due to the nature of production of zirconia all ceramic crown, convergence angle of abutment and line angle finishing degree can have an effect on internal suitability of restoration.

This study investigates the differences among residental areas in the health, standard of living, and social relationships of female elderly living alone. The total of 501 subjects(185 from rural areas, 159 from fishing communities, 77 from the islands, and 80 from urban areas) were questioned from May to July, 2006. The research area was confined to Chungcheong Province. The female elderly living alone of this study were an average of seventy-three years old, had a low cost of living, and received little formal school education. Over sixty percent(60.3) of them lived on less than thirty dollars a month which was the recognized Korean poverty level in 2006. The female elderly living alone were evaluated as being in good health, but they themselves perceived their health as being poor. Observed by residential areas, the subjects in urban areas were lower in ADL, and both the urban dwellers and the islanders appeared to be higher in their satisfaction with medical services as compared to those in rural areas and fishing communities. The fishing villagers showed the lowest standard of living for female elderly living alone. The analysis of social relationships as seen in the different residental areas revealed that the female elderly living alone g in urban areas tended to be receiving social supports rather than providing for others, and subjects living in fishing areas and the islands proved to be relatively higher in the exchange of social supports. In relation to offspring, the female elderly living alone in urban areas had a lower frequency of meeting with their children and also a lesser degree of intimacy with them because they lived at a distance. On the other hand, subjects living in rural areas and fishing communities had a higher frequency of meeting with their children and a greater degree of intimacy with them even if they lived at a distance. The study also showed that the female elderly living alone in the islands had a higher frequency of once meeting per three week with their offspring and a higher degree of intimacy with them because they all live in the same islands. In conclusion, the subject living in urban areas appeared to be isolated from their offspring as compared to the other seniors in the study. The female elderly living alone in urban areas suffered from an insufficient network of relatives and neighbors, and they experienced a poor quality of relationships to their offspring. Almost all of the lone seniors in the study had a low score in social activities; however, the female elderly living alone in urban areas revealed a higher level of participation in volunteer activities, group activities, and educational activities. Nevertheless, the lone seniors living in urban areas were not satisfied with their participation in social activities. The subjects living in rural in fishing communities and the islands showed more participation in money-making activities. This study suggests that the policies for female elderly living alone should reflect the differences of regional characteristics.

The purpose of this study is to look into whether there is a possibility to develop the image of the local community in conjunction with green tourism, thus to explore the concrete ways to vitalize local community with diversified green tourism programs. In the pursuit of relating the research of community image-building with comprehensive local characteristics, this study selected the case of Jung Bang I village near Daejeon and analyzed the case through both written materials and on-site investigation. As a result of analysis, first, it was found that community image-building contributed positive effects in terms of the commercialization of the local community and its revitalization. Second, it was observed that community image-building led to form a "green route" that played a role as a passage to link townspeople to the country. It was also verified that those country villages that succeeded in image-building provided the places where people could experience the country and arts, which showed the potential of their roles as educational opportunities. In conclusion, this study will be able to suggest the direction to where the green tourism and image-building projects of the small communities near towns should go, and also provide a substantial guideline to related people regarding how to operate and maintain the local community.

This research aims at investigating the factors that affects the wearing of the nuclear protection equipment by radiology students. We measured the factors related to the wearing of the nuclear protection equipment based on the theory of planned behavior (TPB). We collected 192 survey records from 230 radiology students in Kwang-ju and Chun-nam providence who finished the clinical training. Based on Logistic Regression analysis, we found that the wearing of the nuclear protection equipment is statistically more probable as the level of study is lower, the scale of practicing hospital is smaller, the attitude rating is lower, and the rating of perceived behavioral control is higher. We argue that the development of educational program considering factors like the perceived behavioral control is required to enhance the degree of wearing the nuclear protection equipment in the clinical training of college students.

Purpose: This study investigated medical accessibility on optical stores and ophthalmic clinics of Seoul Special City and six other metropolitan cities. Methods: By using a number of households, population, optician stores, ophthalmic hospitals, and real estate (apartments) standard market price of Seoul Special City and six other metropolitan cities provided by the Commercial District Information System (2016.6) of Small Enterprise & Market Authority, we analyzed the level of healthcare accessibility and business area zones, Statistical analyses were performed with SPSS 18.0. Results: Inchon (household 2,227/population 5,723) had the highest household and population rate per optical store, and Gwangju (1,146/2,979) had the lowest. Gwangju (24,612/63,987) had the highest household and population rate per optical store, and Seoul (10,021/24,432) had the lowest. From the consumer and patient's point of view, lower household rate per optical store is a city with good accessibility to healthcare, but from an optical store and ophthalmic clinic's view, it will have great difficulty due to issues of competition. Conclusions: Consumers and patients should be the center of healthcare. A healthcare system that can provide smooth service anywhere anytime should be constructed. However, most metropolitan cities, including Seoul, have optical stores and ophthalmic clinics densely populated where profitability and liquidity are ensured and causing unbalanced distribution of healthcare. To solve such problems, we need proper distribution of optician stores according to the population proportion and industrial-educational research to find balance point of local healthcare.

Cross contamination between a patient and rescuer or CPR trainees can occur when performing mouth to mouth ventilation during cardiopulmonary resuscitation (CPR). On the other hand, there has been a lack of research on the filtration efficacy of face shields that are designed to protect people from cross-contamination. This study aims to secure the safety of rescuers from communicable diseases in pre-hospital emergency settings and CPR trainees by verifying the protective effects of face shields. The FA shield and CM Shield were used to verify the safety. The bacteria collected from filters used by CPR trainees were incubated. These incubated bacteria were smeared onto the new filters, and were then blown out through the filters using a Bag Valve Mask (BVM) and the pathogens at the front and the back of the filters were checked. While the FA shield was effective in preventing the transmission of pathogens, the CM shield did not prevent the transmission of pathogens. Therefore, some of face shields that received national certification are ineffective in preventing cross-contamination. Accordingly, it is necessary to verify the safety of other face shields used domestically.
