This study focuses on finding out the determinants of relational quality between the supplier and the retailer in the Chinese cosmetics market. A total of 72 questionnaires were collected by surveying beauty shops which mainly do business with the foreign cosmetics suppliers in Shanghai area. The findings support the premise that a retailer's trust in a supplier is positively related to the retailer's commitment. Supplier's ability, guanxi and cultural sensitivity have positive impacts on trust. Formalization, supplier's specific investment and cultural sensitivity affect commitment positively. But the formalization is not significantly related to the retailer's trust. The guanxi is not found to be significantly related to the retailer's commitment yet.

지난 반세기에 걸쳐 우리나라 대도시에서는 집중호우로 인한 피해가 증가했다. 강우 특성의 변화를 야기하는 요인으로 여러 가지가 있겠으나, 그 중 도시화의 영향에 주목할 필요가 있다. 도시화는 여러 가지 기상특성의 변화를 야기하는 것으로 알려져 있으며, 수문순환에도 영향을 줄 수 있다. 우리나라 도시는 한국전쟁 이후 급격히 성장했으므로, 도시화의 영향이 같은 시기 우리나라 도시에서 증가한 집중호우 빈도와 관련이 있을 개연성이 있다. 이에 본 연구에서는 도시화 진행과 강우특성 변화와의 상관관계를 분석하여 이러한 가설을 뒷받침할 기초 증거를 수집하였다. 구체적으로 12개 지점, 37년간(1975~2011)의 일 강우 자료를 이용하여 총 강우량, 연 최대 강우량, 연 중 강우일수, 10/30/50/80 mm 초과강우일수의 경향성을 파악하였고, 도시화의 진행 정도를 분석하기 위해서 시가화면적비, 인구를 고려한 도시화지수(urbanization index, UI)를 구축하여 같은 방법으로 경향성을 파악하였다. 강우특성의 경향을 살펴본 결과, 대상 지역의 총 강우량과 큰 호우사상은 해마다 증가하는 추세로 확인되었으며, 나머지 강우 특성에는 큰 경향성이 없는 것으로 확인되었다. 최종적으로 UI의 변화와 강우특성 경향 간의 상관관계를 비교한 결과, UI는 50 mm 이상 강우일수, 80 mm 이상 강우일수, 총 강우량과 높은 상관관계를 보이는 것으로 확인되었다. 결론적으로, 도시화가 진행되는 정도에 따라 큰 호우 사상의 발생빈도가 크게 달라진다고 볼 수 있다. 따라서, 향후 도시화의 진행에 따른 집중호우의 피해를 예방하기 위해서는 해당 분야의 지속적인 연구가 필요하다고 판단된다.

최근 기후변화로 인하여 강수량 및 집중호우 발생 횟수의 증가에 따라 홍수의 발생 빈도 및 강도가 증가한다. 기후변화에 따른 미래의 강수량 예측은 2013년에 발간된 IPCC(Intergovernmental Panel on Climate Change) 5차 평가보고서 (AR5)를 활용하여 분석하고 있다. 기후변화 시나리오에 따라 기온 상승률 및 강수량의 증가량, 극한 강우사상의 발생 빈도 및 발생정도가 다르게 결정되며, 극한 강우사상으로 유발되는 홍수의 피해 정도가 홍수피해 유형별로 다르게 나타난다. 본 연구에서는 기후변화에 따른 미래의 홍수 피해 정도를 예측하기 위하여 홍수에 영향을 미치는 인자 및 홍수를 감소시키는 인자들을 활용하여 단계적 회귀모형을 이용하여 인명피해, 피해면적, 피해액, 발생빈도 등 홍수피해 유형 별로 현재 및 미래의 홍수피해정도를 예측 및 분석하였다. 홍수에 영향을 미치는 인자로 연평균강수량, 일최대강수량, 1시간최대강수량, 10분최대강수량, 호우일수, 인구밀도, 자산밀도, 도로현황, 시가화율 등을 사용하였고, 홍수 피해를 감소시키는 치수대책으로는 하천개수율, 하수도보급률, 양수량, 유수지용량 등을 사용하였다.

This study considers inter-jurisdictional fiscal externalities between a central city and suburbs, rigorously examines. and empirically tests the suburban-exploitation-of-central-cities hypothesis. Using micro-migra4ion data, house-holds 'intra-metropolitan migration between 1985 and 1990 Is examined based on a random utility model. It is found that efficient population distribution between a central city and suburbs can be achieved when local government stake into account inter-jurisdictional externalities. External aids from the federal and state governments should be given to public services such as education, welfare, health, and employee retirement services, if they intend to arrest central city decline. Regional tax sharifs can be another way of dealing with these externalities.

Objectives: This study aimed identify of the level and effect of the e-health literacy and health behavior in health science majors Methods: The data was collected from March 5 to March 15, 2018 for student majoring in health science at a university in the C city. The data were analyzed with the SPSS 21.0. Results: First, the e-health literacy were statistically significant in grades (F=5.769, p=0.001), health interest (F=10.553, p<0.001) and health care time (F=3.841, p=0.023), and health behavior were statistically significant in subjective health condition (F=5.476, p=0.05), health interest (F=16.716, p<0.001), and health care time (F=28.479, p<0.001). Second, the e-health literacy were correlated with grades, health care time, economic level and health interest, and health behavior were related to health care time, e-health literacy, subjective health condition and health interest. Third, health behavior related factors were health care time, e-health literacy, grades, subjective health condition, and health interest. Conclusion: The related knowledge and skills should be applied to basic classes in order to ensure that health science majors care can accurately utilize the information on the e-health.

This study aims to examine how the Chinese popular culture, especially music, can contribute to diversification of the ancillary materials for teaching Chinese language, literature and culture, based on the analysis of some songs of Jay Chou. For this purpose, this study analysed 10 songs that have been used in the tests or the text contents in China or Taiwan in terms of rhyme, words relation to the ancient poems, and the Chinese culture. Consequently, the songs of Jay Chou show that they can be used as an ancillary material in the Chinese class from the linguistic, literary, and cultural angles. For use in the Chinese language, literature, culture class in the future, there is a constant need to discover and analyse new materials from the Chinese popular culture.

The purpose of this study was to analyze the effects of digital literacy and the frequency of contact with children or grandchildren via ICT on cognitive functions of 8,942 adults over age 65 who responded to the 2017 National Survey of Older Koreans, using multiple regression analysis. We found that digital literacy was the most significant factor on cognitive functions of the elderly. Also, the frequency of contact with grandchildren via ICT was a positive factor for cognitive function and had a positive correlation with digital literacy. Based on this results, the importance of digital literacy education and intergenerational communication via ICT were discussed.

Particle and noise are effectively used to implement unspecific VFX like an explosion, magic. Particle can create freely but, The more usage, the higher CPU/GPU usage. This paper using polygon mesh that is hard to change but consumes fixed resources to overcome the demerit of particle and reduce CPU/GPU usage. Also, using shader, apply noise texture that is suitable unspecific pattern to vertex and surface texture mapping of polygon mesh for implement VFX in unity. As a result of experiment, shader applied sphere polygon mesh show 2~4ms CPU, 1~2ms GPU usage in profiler. Also It has been shown that shader can be used to implement unspecific VFX.

가뭄은 수개월에서 수년에 걸쳐 평년보다 낮은 강수량을 특징으로 하는 극심한 기후 현상으로 크게 기상학적 가뭄과 식생 가뭄 또는 농업 가뭄, 수문학적 가뭄, 사회경제적 가뭄으로 구분할 수 있다. 본 연구에 사용된 기상학적 가뭄지수는 표준강수지수 (Standardized Precipitation Index), 증발수요가뭄지수 (Evaporative Demand Drought Index), 표준강수증발산지수 (Standardized Precipitation Evapotranspiration Index), Copula 기반 결합가뭄지수 (Copula-based Joint Drought Index)이다. 식생지수는 0부터 1까지 0.05 간격으로 가중치를 적용하여 21개의 식생건강지수(Vegetation Health Index)를 사용하였다. VHI는 널리 사용되고 있는 원격탐사자료 기반의 가뭄지수이며, 이는 식생상태지수 (Vegetation Condition Index)와 열상태지수 (Thermal condition index)의 선형 결합으로 이루어진다. 기상학적 가뭄지수와 식생지수 사이의 상호의존도 및 민감도를 분석하기 위해 상관성 분석을 수행하였으며, 이를 토지피복 유형 (시가화 건조지역, 농업지역, 초지, 산림지역)에 따른 분석도 수행하고자 하였다.

Purpose: The purpose of this study was to identify the impact of cognitive flexibility and e-learning digital literacy on the learning flow of nursing students who had experienced e-learning. Methods: The research design for this study was a descriptive survey using convenience sampling. Data were collected using online questionnaires completed by 134 nursing students in Andong city and Pocheon city. The data were analyzed using percentages, mean values, standard deviations, Pearson's correlation coefficients, and multiple regression with SPSS for Windows version 22.0. Results: Positive correlations were found between learning flow and e-learning digital literacy (r = .43, p < .001), between learning flow and cognitive flexibility (r = .52, p < .001), and between e-learning digital literacy and cognitive flexibility (r = .65, p < .001). In the multiple regression analysis, cognitive flexibility (β = .42, p < .001) was a significant predictor that explained 27.8% of variance in learning flow. Conclusion: The results of this study show that cognitive flexibility is a factor influencing learning flow in nursing students. Based on the results of the study, educational programs aiming to improve learning flow should include methods that improve cognitive flexibility.
