The cool surface ratio could be used as a proxy of the overall thermal environment contributing to heat islands in urban area. This research proposes a comparative evaluation framework in an objective and quantitative way for measuring cool surface ratios. Two university campuses (Kyungpook National University: KNU, South Korea and UC Davis: University of California, Davis, USA) were selected as case study sites in order to monitor cool surface condition. Google Earth combined with digital maps realistically identified the major type of cool surfaces such as cool roofs and water bodies in the study area. Cool surfaces were sparsely identified over the KNU campus while the UC Davis campus was heavily covered by cool surfaces such as cool roofs and water bodies, resulting in almost four times more first-grade cool surfaces, as compared to KNU. It is confirmed that standard remote sensing technology can offer the viable method of measuring and comparing the campus-wide cool surface condition. It is anticipated that this research output could be used as a valuable reference to initiate a nation-wide cool surface strategy since objective evidence has been provided based on area-wide measurement for the cool surface in the two university context.

In the contemporary era of smart tourism, travelers face more accommodation options than ever before. The rapid expansions of alternative accommodation sector are partially owing to the growth of electronic commerce and the rise of online intermediary platforms. Online travel agencies serve as a critical distribution channel for tourism sectors, and the significance is further increased for small and micro entrepreneurs whose direct communication channels are scarce. Considering the holistic process of customer experience started with a third-party online intermediary, this study explores basic and extended attributes of small and medium-sized alternative accommodation where the comparative value is created. In order to achieve the objective, a research design was developed to synthesize the qualitative evidence. The synthesis encompasses both theoretical and practical perspectives, from a systematic review and opinions of academic professionals to an in-depth interview with an industry expert and the current practices of online travel agencies. This study suggests that the sources of value creation for alternative accommodation are not always consistent with those of the traditional. Accounting for the temporal and spatial dynamics in customer experience, the findings of this study provide insights on the comparative value of alternative accommodation, to both academic and industry audiences.

It has been extensively known in the high temperature regions such as southern China and south east Asia that Korean ginseng(Panax ginseng) intake raises body heat, while American ginseng(Panax quinquefolium) lowers it, based upon oriental medicine. This is likely due to the misunderstanding of the conception that Korean ginseng shows a warm property, resulting in enhanced blood circulation and stimulation of metabolism. It's further supported by the fact that current scientific studies have shown no notable side effects. Moreover, it has been demonstrated in animal experimental test that Korean ginseng shows a complementary effect in a high temperature environment, together with scientific evidence of a preventive effect of ginseng saponin against cold conditions, suggesting it to exhibit an adaptogenic effect normalizing the body under abnormal body conditions. However, there is a shortage of studies published concerning comparative clinical and animal studies of Korean and American ginsengs, and also, on natives of high temperature countries. Therefore, a further placebo-controlled clinical study has to be considered to elucidate scientifically clinical evaluation of Korean and American ginsengs on the body heat. In this article, we summarize the scientific publications reporting the clinical comparative study of Korean and American ginsengs on body heat response.

This study aimed to suggest more appropriate and accurate festival costumes based on a comparative analysis on various reproduced costumes and a period review of traditional festival costumes. In particular, the comparative analysis examined festival costumes which appeared in Korean and Japanese festival parades during the Baekje Period. The Baekje Cultural and Sacheonwangsawasso Festivals were examined. A literature review as well as field research and digital restorative techniques were used in the study. The reproduction patterns of Baekje costumes from both festivals were compared with original Baekje costumes, demonstrating several differences in the configuration, material, color, and shape of the costumes in addition to the way they were worn. Based on the comparative analysis, Baekje costumes used in Festivals were grouped into three categories: King's Costume, Queen's Costume, and Government Official's Costume. Dress sketches and 3D illustrations also have been presented.

2004년 이후 철도안전에 대한 투자확대의 결과로 철도사고 발생건수 및 관련피해는 지속적으로 감소하여 2009년 이후에는 선진국 수준의 안전성을 유지하고 있다. 그러나 이러한 사고율 개선에도 철도안전에 대한 국민의 우려는 감소하지 않고 있으며, 추가적인 개선을 요구하고 있다. 본 연구에서는 국내 철도안전의 현재 수준에 대한 정량적 평가를 통해 철도안전에 대한 목표설정, 안전대책마련 등의 정책 수립에 활용할 수 있도록 하였다. 철도사고에 대해 철도 사고율이 낮은 선진국 및 도로교통 사고율과 정량적인 비교연구를 수행하였다. 또한 사고 종류별 원인분석을 통해 현재 철도안전수준의 평가를 위한 기초자료를 마련하였다.

The aim of the study is determined to find out how elementary science localization teaching strategy would influence environmental perception of students. In order to fulfill the research purpose, a total of 51 fifth graders from two classes in M Elementary School in U City were divided into a 26 of experimental group and a 25 of comparative group. The study was carried out from September to November of 2012. For the experimental group, an elementary science localization classes were conducted while for the comparative group, a general science classes were performed. The results of the research are presented as follows. First, it was learned that the experimental group with the elementary science localization class would have a significantly and statistically high environmental sensitivity comparing to that of the comparative group. That proves the elementary science localization class's being efficient at improving the students' environmental sensitivity. Second, the experimental group with the elementary science localization class turned out to have a significantly and statistically strong will to protect the environment than the comparative group would do. Such finding says that the elementary science localization class is helpful to enhance the students' will to preserve the environment. In conclusion, the study came to understand that the elementary science localization teaching strategy can improve the environmental perceptions of the students for such elementary science localization class would efficiently encourage environmental interest of the students.
