This study is an attempt to provide some answers to question about how characteristics and general recognition regarding internet use in Korea and Japan influence fostering and maintaining on-line social network in each of countries. Survey is used to compare Korean internet users and Japanese internet users in terms of characteristics of on-line social network, individual's propensity for internet use, including their recognition on internet. The study's main findings go as follows. First, Korean internet users tend to be more active in using internet than Japanese internet users do, thus having larger on-line social network and more intensive internet use than Japanese internet users do. However, there is a commonality that majority of internet users in both countries use internet to connect them to person with whom they have private relationship but they cannot meet frequently. Second, for Korean internet users, individual's propensity, characteristics, and recognition regarding internet use is not related to how to contact others. To the contrary, for Japanese internet users, how to contact others in on-line setting seems to vary according to whether or not they have relation-oriented internet use and how they recognize the availability of internet. Third, a commonality regarding the size of on-line social network is found between Korea and Japan that the total numbers of people enrolled as network increases if people use internet in order to get information. This confirms previous finding that relationship based on weak tie is instrumental in fostering on-line social relations and likely produces advantage in getting information. Finally, for Japanese internet users, the degree of risk recognized in on-line setting, that is the degree of interpersonal trust, appears to greatly influence overall relationship -building in on-line.

As foreign investors' share holdings in Korean firms have dramatically increased since 1998 following the financial deregulation on the limit of foreign stock investment, the concern over the negative impacts the foreign investors would bring on the firms' financial policy has been growing too. Foreign investors were perceived to require the firms of excessive payments of cash dividends sometimes with threat of hostile takeover trials detering the firm from investing its cash flow in the physical facilities and RandD eroding their potential growth capabilities. We examine the impact of foreign investment on the firms' dividend policy using 234 listed firms' panel data over the sample periods of 1998 to 2005 employing various panel regression methodology. Foreign shareholders are found not to be related or even negatively related to the payout ratio(dividend/net income), but positively and statistically significantly related to the ratio of cash dividends to book of asset, negatively to the dividend yields. Considering the payout ratio is the most appropriate measure for the dividend payment, we can not support the arguments that the foreign investors' holdings have induced the excessive dividend level in Korean firms.

In terms of both economic growth and social welfare, this paper discusses the optimal proportion and size of basic research budget by adding knowledge stock to an endogenous growth model. On the basis of the modified endogenous growth model, this paper derived an equation that consists of kinds of parameters and suggested this equation as a criterion for determining whether allocated basic research budget has been appropriate. This paper also found that the theoretical optimal ratio between government investment spending and investment in basic research is equal to the ratio between the partial elasticity of output with respect of public capital stock and the partial elasticity of output with respect of knowledge stock. In addition, after the required parameters were specified based on precedent literatures, this paper estimated an optimum size of the basic research budget using the theoretical optimal ratio with official statistical records and compared the estimated size to its actual size. This paper therefore is expected to contribute to budget planning and allocation regarding establishing basic research policy, because the results of this paper presents a useful criterion for optimum level and an approximate size of investment in basic research. However, it should be noted that although the optimal solution is optimal in a economic sense, it may not be the best solution from a practical perspective.

Illegal and harmful information on the Internet have been a great concern not only for regulatory authorities, but also all the public institutes, such as public libraries and schools, that provide Internet access service. In particular, for public libraries which play an important role in organizing, opening and providing information resources in the information society, providing Internet access service are indispensible. Therefore, any changes of Internet content regulatory system may have direct effects on services of public libraries. Due to unique characteristics of the Internet, content refutation on the Internet has made a best use of various regulatory methods, ranging from governmental regulation to self-refutation and technical regulatory methods. However, nation by nation. technical regulatory methods on the Internet have been developed in quite different ways. Applying them on public library has been strongly criticised for violating freedom of expression and rights of access to information. This article begins with a theoretical discussion about free speech rights and refutation on Internet. Then it examines filtering software which is one of the most popular technical regulatory methods based on both technical and socio-humanities' prospects and analyses several governments' regulatory approaches to Internet filtering. As a conclusion, issues concerning Internet filtering at public institutes are critically apprised.

세계화, 국제화, 개방화 시대에 살고 있는 우리가 통과의례나 전통 명절과 같은 특별한 행사에 의례복으로 한복을 애용하는 것은 한복이 한국의 문화적 이미지를 강하게 간직하고 있는 한국적 조형물 중의 하나이기 때문이다. 더우기 의례복은 특별한 행사 자체를 위해 착용되었던 만큼 당시대의 내 적 가치를 가장 현저하게 표출하고 있는 복식으로 인정 할 수 있기 때문이다. 본 연구의 목적은 시대 적으로 현대 전통 한복의 기본 형 식을 제공한 조선시대와 그 이후의 복식 중에서 특히 분명한 착용동기와 목적, 복식을 통해 나타내고자 하는 상징성 등을 함축하고 있는 아동용 의례복을 대상으로 복식의 형태, 색채, 문양, 소재 등의 조형 요소를 고찰하는 것이다. 또한 양식적 특성을 살펴보고, 그러한 조형적 특성을 형성시킨 당시대의 사상적 가치를 추론해 보는 것이다. 구체 적인 연구 방법은 먼저 관련된 문헌 고찰을 통한 이론적 배경을 토대로 하여 아동용 의례복의 범주를 설정하고 현재 보전중인 실물과 또는 사진, 풍속화에 나타난 복식 자료들을 수집하였다. 그리고 당시대의 사상적 배경에 대한 고찰을 병행하여 이들에 내재된 문화적 가치를 추출해 보았다. 연구 결과 양식적 특징으로는 남아의 두루마기나 전복 그리고 쓰개류 등에서 기능성을 고려한 변형적 양식이 나타나고 있었다. 색채 역시 음양 보색이나, 오행색을 바탕으로 한 기본색의 구성 이외 에도 소매나 섶에 응용된 색의 배열이나 맞깃 전복의 깃에 나타난 색의 조화는 다양한 색의 조형미를 표현하고 있었다. 특히 색동 등에 나타난 오행색의 배열, 안감과 겉감, 상의와 하의, 외의와 내의에 사용된 색의 조화는 미의식에 관한 문화적 가치를 추론해 볼 수 있다. 더우기 장식 표현에 주로 쓰인 자연물 문양이나 글자 문양은 당시의 지배 사상이 지향하는 덕목 이외에도 전통적으로 내재된 수명과 복록, 부귀와 영화에 대한 내적 가치들을 반영하는 조형적 상징들이라 할 수 있다. 소재는 비교적 계절을 고려하여 사용되고 있었지만 의례적 성격을 지닌 외의나 쓰개류의 경우 계절적 구분을 고려하지 않은 경우도 많이 나타나고 있었다. 장신구의 경우는 많이 사용되는 것은 아니나 역시 상징적 인 가치를 표현하는 실물들을 미적으로 재구성한 사례들이 나타나고 있었다. 이상의 연구를 통해 아동용 전통 의례복은 형태, 색채, 문양, 소재, 장신구 등에서 양식의 다양성과 변형들을 알 수 있었다. 또한 적극적인 내적 가치의 상징들을 복식을 통해 표현하고 있었음을 알 수 있었다. 현대 복식의 디자인에 있어 아동용 의례복에 나타난 창조적인 양식의 변형과 다양성 그리고 복식을 통한 내적 가치의 반영 등이 현대 사회와 조화를 이룬 실질적인 복식 디자인 제시 및 창작에 작은 영감으로 작용하길 바란다.

In the historical and cultural blocks with the most concentrated urban cultural heritage, the development of both side streets is impacted by the development of the main street, which shows a gradual decline. The loss of placeness on both side streets has resulted in more empty houses. Therefore, it is urgent to pay attention and take countermeasures to the empty houses in historical and cultural blocks. In this study, the vacant houses on Zhongshan Road in Hangzhou, China were taken as the object of study to understand the location theory and the six dimensions of Matthew Carmona's urban design. Meanwhile, it further analyzed the evaluative features of the placeness of the vacant houses in the historical and cultural street, to provide direction and basis for the flexible using of other empty houses in Zhongshan Road. Then by applying the Analytic Hierarchy Process (AHP), it obtained the importance scale of each evaluative feature and compared the evaluation results of experts with the analysis results of cases, getting the results as follows: In the flexible application of vacant houses in historical and cultural street, the evaluation result of placeness indicates that this kind of usage should be in order of societal level, perceptional level, functional level, morphological level, visual hierarchy and temporal level; among the evaluative features, security, identity, usability, individuality, aesthetics, connection, diversity, openness, continuity, accessibility, order and history should be considered in turn.

Learning at the elbow of scientist is a well-known educational approach to improve students' understanding of science and scientific practice. This study, in the perspective of legitimate peripheral participation in a community of practice, explores how students' scientific practice and perception could be shifted through R&E program with the development of participation. Data from participant observation for 18 months and in-depth interviews were analyzed based on constant comparative method to extract common characteristics of students' participation and major shifts in their scientific practices and perceptions. Students' development of participation was categorized into three stages: legitimate, peripheral, and full participation. In the stage of peripheral participation, students perceived themselves as mere students and showed passive engagement. They just followed the directions of researchers and didn't know what they should be doing. But through continuous participation, students showed enhanced engagement like voluntary article reading, role assignments, and establishing norms in a community of practice with the reference of scientists'. In this stage of transitional participation, students also showed a deepened perception on everyday life of scientist and the community of scientist. And finally in the stage of full participation, students showed responsibility and ownership on research and continuous efforts to refine their research. They recognized themselves as beginning scientists. With these findings, this paper highlighted the dynamic processes of students' development of scientific practices and identity through R&E participation. It also suggests implications for research programs for education, especially for students who have already articulated a science-related career but still have only foggy notions about science.

As globalization of communication is going on and as the media have become increasingly central to the world economy, media policy matters have become the province of world economic organizations like the IMF and the WTO. The WTO service negotiation is focused primarily on the discriminatory and quantitative barriers associated with the trade of audiovisual services. Domestic measures such as subsidization, content regulation including quotas, and licensing requirements and restrictions on foreign ownership and control are at issues here. These measures have been successfully implemented by countries wishing to withstand competition from the American audiovisual industry. The debate about trade in audiovisual services is permeated by the unstated assumption that these programs are pure commodities whose production, distribution, exhibition and in turn, values are solely determined by the market forces. It is therefore presumed that liberalization of trade in audiovisual services will benefit all, serving cultural pluralism and diversity as well as economic efficiency. However, this assumption is not shared by developing countries, the recipients of U.S. television material. They argue audiovisual sector requires a social and cultural approach, since it plays a key role in the preservation of people's identity and social bonds. They claim that it is the each state's right to define its media policy and to implement it through the means it considers fit. These clashing views over the nature of the audiovisual material and the ways in which protect cultural pluralism and diversity do not confine to be the realm of theoretical debate. Each state's interest and motivation to protect its local industry and to have a competitive advantage in the international market is working in this battle. Consolidation with the countries like Australia, Canada, and EU nations, in favour of cultural exemption, seems to be the best policy for us. However, we are not entirely free from the WTO pressures, considering relation to the U. S. This study analyzes Korean Broadcasting Law compared with those of other OECD countries and tries to propose some strategical guidelines facing WTO service negotiation in the area of broadcasting.

This study investigated subtypes of men who batter, and explored the differences among them. It was based on 217 subjects from all around the nation who received legal punishment. In the analysis of the typology, we specifically tested whether the Holtzworth-Munroe and Stuart proposed typology was verified. The results of the cluster analysis revealed support for their theoretical distinction for three types of abusers. These results imply that Holtzworth-Munroe and Stuart's batterer typology is applicable to Korean batterers to some degree. Type 1 men demonstrated the lowest levels of physical and psychological abuse toward their wives and were the least likely to have had a history of child abuse or alcohol problems. These men had lower MCMI scores and did not show any extraordinary personality traits. Men in this category were violent only against their wives, had relatively liberal sex role attitudes and had the most satisfaction in their intimate relationships. Type 2 men were violent only at home, using a moderate level of violence. These men had very high levels of dependency on others and showed a borderline, avoident or passive-aggressive personality. The amount of alcohol consumption was similar to Type 1, but scores of jealousy, self-esteem, and attitudinal variables were similar to Type 3 men. They lacked assertiveness skills and reported the least marital satisfaction. Type 3 men used the most severe violence and were violent both inside and outside the home. These men showed signs of antisocial and aggressive personality. They had experienced frequent physical abuse during childhood, were the most likely to abuse alcohol and had lower self-control. Type 3 were the most traditional in their views of women's roles and had attitudes supporting violence. Based upon the study findings, practical implications of enhancing treatment efficacy were considered.
