  • The two-spotted spider mite (Tetranychus urticae) has sustained damage on more than 200 host plants worldwide. Many farmers have relied on chemical acaricides to control mite, but the abuse of acaricides has caused serious resistance to mite. To overcome this problem, microbial control using entomopathogenic fungi have been studied. Entomopathogenic fungi have been an important role against the control of pest, and most of their culture products have been demonstrated to have virulence against pest population. In this study, we evaluated and compared the virulence of culture filtrates, aerial conidia and blastospores of selected Metarhizium anisopliae 4-2 and Beauveria bassiana 2R-3-3-1, respectively, among two-spotted spider mite-pathogenic fungi. As a result, the virulence was confirmed in all treatments, and the accumulated mortality rates were between 77 and 100% within 7 days. Especially, treatment with the fungal culture filtrate alone exhibited quite high virulence, and combined treatment with aerial conidia or blastospores enhanced activity. However, the median lethal time of treatments was not significantly different. When two isolates were compared, M. anisopliae 4-2 showed higher virulence than B. bassiana 2R-3-3-1. These results suggest that the selected two fungal isolates and their culture products could be used effectively for the control of two-spotted spider mite.

  • Clothing exports of Korea have been steadily declining since 1990, but its international competitiveness will be continued in the future because of its history and technology. The purpose of this study is to find out the characteristics of knitted clothing exports of Korea compared to China. Statistical data of knitted clothing articles(HS 61) $2000{\sim}2008$ were used for analyses. The results of the study were as follows: First, the proportion of knitted clothing export out of the total clothing export has been consistently increased in Korea and China both, it is similar now. Second, export articles of large proportion are different between Korea and China. Socks, gloves and fancy goods became major export articles in Korea and men's and women's clothing in China in late 2000's. Third, the unit price of Korean export clothing is higher than that of Chinese from two to ten times. Generally the growth rate of unit prices of Korea outpaced that of China. The results of this study will help Korean export firms to develop competitive export articles and make out export strategy.

  • Many studies such as Pepin (1999a; 1999b), Kaiser (2002), and Park & Leung (2006) revealed that there is a strong dependence of mathematics teaching on cultural traditions in different countries. This study was set up as a detailed comparison between the intended curricula in Berlin and Hong Kong to explore how cultural tradition influenced the intended curriculum. In this study, the intended curriculum is what the (local, state or national) curriculum developers stipulate in the official documents. The German educational system is influenced by the curriculum tradition called Didaktik. Didaktik is a tradition about teaching and learning. Since 16th century, Didaktik has been the most important tool for planning, enacting, and thinking about teaching in most of northern and central Europe (Westbury, 1998). On the other hand, the education system in Hong Kong is influenced by both the Anglo-Saxon curriculum tradition and the Confucian heritage culture (CHC). It was found in this study that, although many studies revealed that there is a strong dependence on cultural traditions of mathematics teaching in different countries, other factors such as social factors or the education system also played an important part in shaping the intended mathematics curriculum. So a simplistic view of dependence of the curriculum on cultural traditions is not warranted. The formation of the curriculum is a much more complicated process encompassing various factors including needs of society, advancement of technology, and government policies at different levels.

  • 본 논문은 한국 커뮤니티 시네마 운동의 변화 과정과 특징에 관한 연구이다. 2010년대 이후 활발해지는 커뮤니티 시네마 운동은 한국 영화문화 운동의 전환점이라 할 수 있다. 하지만 커뮤니티 시네마 운동에 대한 학술적·정책적 정의와 연구는 극히 미흡하고, 몇몇 세미나나 정책 연구보고서에 등장할 뿐이다. 본 연구는 한국 커뮤니티 시네마 운동 특징들을 한국 대안상영 운동의 흐름 속에서 발견하고자 한다. 한국 대안상영 운동에 대한 통시적 접근과 커뮤니티 시네마 사례에 관한 비교분석 연구를 진행하여 한국 커뮤니티 시네마의 특징을 파악하고, 아직 지원 체계가 준비되지 못한 커뮤니티시네마 정책 방향성을 제시하고자 한다.

  • Architecture has been expressed a complexity of their civilization with evolving into a living spaces and a crystalloid of culture in the times. So, architecture is always a dramatic phenomenon related to architectural aesthetic and technical expression in harmony with social and cultural issues by the times. From this point of view, we can describe that architecture is one of an important mediators to analyze the integrated trend of time. Specially an expressed building envelop which is a matter of consequence in the architectural component is first visual factor including architectural meaning and historical back ground. Therefore, this study firstly starts an investment for discriminative characteristics of building envelop design in the times, then will take the comparative analysis related with modern age and contemporary age based on phases of the times. This research will give the chance to prepare of the pillar of future envelop design in the practical affairs and has simultaneously the chance to understand of inclusive envelop design methodology by the changes of the times.

  • This study investigates the different pattern of trade negotiation between Korea and Japan. For the Korea, it is inevitable to enhance nation's competitiveness position amid the rapidly changed international environment. Especially, Korea's recent experience of IMF credit under economic crisis during 1997-1999 tells us the importance of international trade and trade negotiation. Our main interest is focused on the comparative pattern of both countries with the recognition that the role of the negotiation can not be overemphasized for the Korea. This is because Korea has continuously recorded the huge trade deficits with Japan for the long time. Although we consider the different degrees of products quality, industrial structure, productivity, and national competitiveness of both countries, it is necessarily required to pay special attention on different pattern of negotiation skills and tactics between two countries. In the paper, we suggest some important guidelines for Korea to improve its negotiation technique with Japan. First, valuing human relation between negotiators, rather than negotiating process. Second, preparing for negotiations: the negotiators should try to carve out enough time to prepare for the bargaining. Third, appreciating the power of patience: very essential to effective outputs. Fourth, being a specialist on both countries' culture and avoiding lawyers' intervention for conflict resolution.

  • Since national image video advertisements are a means of public relations with wide delivery and major repercussions at home and abroad, this study performs a comparative analysis of video advertisements aired by previous governments as reported by Daejung Kim, Moohyun Roh, Myungbak Lee, and Geunhye Park. The characteristics of the previous governments, whether or not social trends were reflected, and the importance of traditional and modern elements were examined. As we describe, there are clear differences in video advertisements by government regime, and while messages expressing traditional values of Eastern culture have gradually decreased, reflecting the trends of the times, the messages emphasizing the modern values of the West have gradually increased. Our research confirmed that traditional elements such as 'Samulnori' and 'Taekwondo' are gradually disappearing. In addition, it was confirmed that the collective values, traditional values, and humanism represented by the 'large crowd' and 'traditional elements' in the Kim Dae-jung and Roh Moo-hyun administration changed in the Lee Myung-bak and Park Geun-hye administrations to more individualistic, materialistic, Western values. This study is meaningful in that it analyzed the components and characteristics of national image advertisements by governments in the past, how social trends were reflected, and the weight difference between traditional and modern elements. Based on this research, the significance of the current Moon Jae-in government's groundwork for follow-up research should not be understated.
