Background: Although deleterious effects of sunlight have been increased recently, the surveillance of the attitudes toward sun-exposure and the behavioral aspect of using sunscreens in Koreans has hot been carried out. Objective: Our purpose was to evaluate the attitude toward the harmfulness of sun-exposure and behaviors of using sunscreens in Korea. Method: Five hundred and fifty-two subjects were surveyed to assess the attitude toward sun-exposure, as well as the subjects knowledge about, and the use of sunscreens. Underlying data including demographic data, skin colors, skin types, occupation, and sun-exposure, were obtained. Results: Fifty-four percent of subjects believed that sun-exposure is bad for their skins, but, on the contrary, 12.5% believed it to be beneficial. Fifty-two percent of subjects used sunscreens. Almost all subjects(93.8%) knew why to use sunscreens but 62.7% of subjects did not know the meaning of sun protective factors(SPF). Women, indoor workers, subjects less than 40 years old, with less sun-exposed, fair colored skin, or with skin type I, II, III tended to know the deleterious effects of sunlight and the meaning of SPF and used more sunscreen. Conclusion: High risk population-men, outdoor workers, subjects oider than 40 years old, with more sun-exposed, dark colored skin, or skin type VI, V could be targeted with campaigns that promote attitudinal and behavioral changes.

This study examined the impact of community facilities on parents` perceptions of visiting public libraries. Previous research on public libraries has focused on the services provided by libraries, including the provision of information and the space for holding programs in the buildings. Urban planners have also insisted that the interaction between primary and convenience functions makes libraries work best. However, previous research has paid little attention to the connection between libraries and community facilities. We investigated whether the proximity of parks and transportation services has an impact on parents` perceptions on visiting libraries with their children. A field survey was conducted at 8 public libraries in Busan Metropolitan City, and the data from 488 respondents were analyzed with the ordered logit model. The results revealed that parents were more likely to visit public libraries near parks. Therefore, librarians, policymakers, and urban planners should consider the location and function of public libraries in relation to community facilities/services during the urban planning and design process to encourage the use of public libraries by parents and their children.

본 연구는 지리산국립공원 심원계곡 생태경관 복원공사지역의 모니터링 결과를 분석하여 체계적인 복원관리를 도모할 수 있는 기초자료를 확보하는데 그 목적이 있다. 복원사업이 완료된 2017년도에 식생 모니터링을 위한 조사구 12개소와 대조구 4개소를 설치하였고, 2017년과 2020년의 상대우점치, 종다양도지수, 유사도 등의 변화를 분석하였다. 복원사업 시 수목이 식재되었던 조사구는 종다양도지수가 0∼1.4552로 나타났고, 대조구와의 유사도지수에서는 1개 조사구가 1.32%로 분석된 것을 제외하고 모두 0%로 나타났다. 조사구의 종다양도지수 및 유사도지수가 매우 낮은 것은 복원사업 시 식재된 수목이 고사하거나 멧돼지 피해, 유수에 의한 침식으로 유실되는 등의 영향으로 판단되었다. 반면 복원사업 시 수목이 식재되지 않은 미식재 조사구는 종다양도지수가 0.9538∼2.3222로 나타났고, 유사도지수는 최대 8.33%까지 분석되었다. 국립공원 생태경관 복원공사지역의 복원 공법 개발을 위한 장기 모니터링과, 미식재 조사구의 천이과정을 분석하는 지속적인 연구가 필요하다. This study aims to obtain basic data for systematic restoration by analyzing the monitoring results of the Shimwon Valley Ecological Landscape Restoration Project area in Jirisan National Park. In 2017, when the restoration project was completed, 12 monitoring plots and 4 control plots were installed for vegetation monitoring, and changes in the relative dominance, species diversity index and similarity between 2017 and 2020 were analyzed. The species diversity index of the surveyed areas where trees were planted during the restoration project was 0-1.4552, and the similarity index with the control group was 0% except for one survey area at 1.32%. The very low species diversity index and similarity index in the survey areas were attributed to the loss of trees planted during the restoration project due to death, damage by wild boars, or erosion by running water. On the other hand, the species diversity index was 0.9538-2.3222 in the monitoring plot where no tree was planted, and the similarity index was analyzed to be as high as 8.33%. It is necessary to continue the long-term monitoring for the development of ecological landscape restoration methods in the national park and analysis of the succession in monitoring plots where no trees were planted.

To investigate the effects of priming with BCG and levamisole on the immune responses of the guinea pigs inoculated with CPV-intact antigen(CPV-IA) and recombinant CPV-subunit antigen(CPV-SA), hemagglutination inhibition(HI) test and leucocytes migration inhibition(LMI) test were applied for measurement of antibody and cell-mediated responses, respectively. 1. The minimal concentration of CPV-IA and CPV-SA to evoke HI antibody in guinea pig was 1,000 HAU and 2,000 HAU, respectively. 2. As the effects of priming with BCG and levamisole were examined by HI test, double primings showed higer HI titers than single priming and the groups primed with levamisole showed higher HI antibody titers than groups primed with BCG. All of groups primed with BCG and levamisole revealed prominantly higher HI titers than the non-primed group. 3. The optimal conditions for LMI were 64 HAU for antigens, 1×10^6 cell/ml for the concentration of leucocyte and 2 hrs for antigen-leucocyte reaction time. 4. When the cellular immune responses for the guinea pig inoculated with CPV-IA were examined by LMI test, BCG-primed groups showed significantly higher %LMI than the levamisole-primed group(P<0.05). Double primings revealed a tendency of higher %LMI than single priming, but statistically not significant. All of primed groups showed significantly higher %LMI than non-primed groups (P<0.001). 5. When the cellular immune responses for the guinea pig inoculated with CPV-SA were examined by LMI test, BCG-primed groups showed a tendency of higher %LMI than the levamisole-primed groups and double primings revealed higher %LMI than single priming in both of BCG and levamisole. All of priming groups showed significantly higher %LMI than the non-primed groups (P<0.001).
