People could possess different self-identity under virtual world from physical world because of anonymity of the virtual world and this difference could influence their behavior in the virtual world. Based on self-discrepancy theory, this research proposes that continuous use model in self-expression goal. We defined the difference bet ween actual self~identity and ideal self~identity in the virtual world as "self-discrepancy in virtual world", and the difference between actual self-identity in the physical world and actual self-identity in the virtual world as "cross-world self-discrepancy". Before testing hypothesis, we compare the actual self-identity in the online community with the actual self-identity in the physical world, and with ideal self-identity in the virtual world. We derived an index for two different types of self-identity in terms of Personal Self-identity and Social Self-identity through factor analysis. Our results show that online community members have a higher level of ideal self-identity than actual self-identity in online community, and they have better personal self-identity in online community than physical world while a lower level of social self-identity in online community than physical world. The results of the hypothesis testing analysis based on 300 respondents showed that "self-discrepancy in virtual world" negatively influenced perceived usefulness for self-expression while "cross-world self-discrepancy" positively influenced perceived usefulness for self-expression. The perceived usefulness for self-expression and ease of use positively influence both continuous use and knowledge contribution. Specially, the effect of perceived usefulness for self-expression on knowledge contribution is much bigger than the effect of ease of use. This study extends self-discrepancy theory to virtual worlds by suggesting various types of self-discrepancy and by applying the effect of self-discrepancies in online community. Also, this study extends technology acceptance model in the personal goal in terms of self-expression. This study hopes to offer practical insights by suggesting positive effect of self-discrepancy on behavior in the online community.

우리나라는 세계5위의 타이어생산국으로 국내 타이어시장은 2010년까지 생산과 수요는 증가할 것이지만 성장률은 연평균3% 이내로 정체될 전망이다. 세계 타이어시장 성장률도 3% 수준에서 정체될 것으로 보이는 상황에서 천연고무 가격급등, 유가인상 등으로 경영환경이 악화되고 있으며 , 이를 극복하기 위해 국내외 타이어업체들은 마진율이 높은 고부가타이어의 매출비중을 적극적으로 확대하고 있는 상황이다. 세계 타이어시장은 상위 12개 업체가 과점하고 있으며, 같은 성능과 품질이라도 브랜드파워와 판매네트워크의 차이로 뚜렷한 가격 차이를 보이고 있다. UHPT의 경우 국내업체제품은 선진업체에 비해 40% 할인된 가격에 판매되지만 , 일반타이어를 중심으로 가격차이가 2010년까지 15% 이내로 좁혀질 전망이다.

광과 광, 반도체와 반도체, 기술과 제품, 메이커 등의 차이로 인해 광과 반도체는 각각 개별적인 세계를 형성하고 있었으나, 이제 이 두 개의 세계가 연결되어 이윽고 융합을 향한 움직임을 보이고 있다. 광 네트워크 분야에서 시작된 이러한 움직임은 반도체 기술이 생산하는 새로운 부품으로 시장에 모습을 나타내고 있는데, 그 신제품이 바로 광 스위치이다. 광과 광, 반도체와 반도체, 기술과 제품, 메이커 등의 차이로 인해 광과 반도체는 각각 개별적인 세계를 형성하고 있었으나, 이제 이 두 개의 세계가 연결되어 이윽고 융합을 향한 움직임을 보이고 있다. 광 네트워크 분야에서 시작된 이러한 움직임은 반도체 기술이 생산하는 새로운 부품으로 시장에 모습을 나타내고 있는데, 그 신제품이 바로 광 스위치이다.

Most of global citizens in the globalization era want to live peacefully in the symbiotic relationship among each region or locality with its identity. From this perspective, the new regionalist models of development such as new industrial districts, industrial clusters, regional innovation systems, and global city-regions isn't helpful to most of regions because they were developed to increase the global competitiveness of industrial region from a few advanced industrial areas. This study attempts to develop 'regional differential development' as an alternative regional development theory. This theory puts emphasis on the truth that the difference or differential industry between regions in the real world connotes two essential values of development like the symbiosis of global citizens and the regional identity. Regional differential development seeks the development of regional differential industry on the basis of geographical elements with differential advantage, and hence it reviews significantly geographical elements including location, natural environment(landform, soil, climate, etc.), natural resources, population, transportation, culture, and landscape which appear substantially differently among regions. And to realize regional differential development successfully, it is crucial that actors(government, company, related institutions, and regional residents) actively participate and play each complementary role in the relationship of cooperation and conflict. Further study needs to secure the universal validity of this theory through many empirical studies.

현재 우리나라의 측량체계는 크게 측지분야와 지적분야로 이원화되어 있으며 측지분야에서는 2001년도에 측량법을 개정하여 ITRF2000좌표계와 GRS80 타원체를 측량기준으로 사용하는 세계측지계를 도입하였다. 하지만 지적 분야에서는 국민의 재산권과 직접적으로 관련이 있는 필지의 경계와 면적의 변화 연구는 미미한 상태이다. 따라서 본 연구는 2010년 세계측지계 도입 후 지적분야에서 발생할 수 있는 필지별 면적 변동에 따른 사회적 혼란 여부를 판단하기 위하여 서울특별시 종로구 숭인등 숭인4구역주택재개발지구를 연구 대상지로 선정하여 세계측지계 전환에 지적 필지별 면적 변화를 분석하였다. 분석결과 연구대상지는 세계측지계와 지역측지계가 종선(X)축으로 305.87m. 종선(Y)축으로 70.87m 편차로 두 좌표계 간 북동방향으로 313.97m의 차이가 있고, 현행성과와 비교한 결과 종선(X) 방향으로는 평균 +4.0cm, 횡선(Y) 방향으로는 평균 -3.0cm의 차이가 나타났으며, 필지별 면적의 변동량은 $1.0m^2{\sim}3.0m^2$ 차이가 있지만 허용오차 범위 내에 있으므로 세계측지계 전환에는 문제점이 없는 것으로 판단된다. 하지만 본 연구의 결과는 그 대상범위가 한정되어 있고 기 검증된 지적기준점 성과를 사용한 결과이므로, 향후 보다 효율적인 세계측지계 전환과 도입을 위해서는 현 지적기준점체계의 정확한 세계좌표계 변환 성과를 기준으로 한 대단위의 필지별 면적 변동량 및 허용범위 분석과 같은 추가적인 연구가 조속히 이루어져야 할 것으로 판단된다.

This paper is to examine the interrelationship between morality (or ethics) and geography and education in terms of the moral and ethical dimension embedded moral turn in geography. Since the 1970s, the geography have morally turned with stressing realization of social relevance and justice through interest on moral issues such as the spatial inequality and human welfare in the world of difference. This moral turn in geography has formed the area of moral geography, and emphasized the ethics of care and responsibility of human and nature with warning of immoral geographies of others and nature in the world of difference with the recent trend of postmodernism. For morally careful geography teaching, it is now good time that geography educators need to think the moral turn in geography education. If geography education is willing to contribute to make a better world, it needs to reflect more morally on geography curriculum and instruction in terms of the ethics of care and responsibility.

The purpose of this study is to compose direction about mUC as a communication channel in the company. Recently, many companies have started to adopt or try to vitalize the use of mUC. This study starts from the viewpoint of communication which is the original purpose of SNS or mUC. The purpose and function of life-world are drawn based on Habermas' theory of communicative action. Firstly, this study will check on a difference in usage over the action and articulation between SNS and mUC. Secondly, this study will examine a difference of effect of life-world between SNS and mUC. Thirdly, to check that there is difference according to the user characteristics. The result is that there are differences about action and articulation but little differences of effect to the life-world between SNS and mUC. Also, there is difference according to the user characteristics. This study could contribute to compose direction when a company adopts or vitalizes mUC.

This research was conducted in an attempt to understand human lifestyles in on-line game world. Q methodology was used to investigate players in Mabinogi, which is an on-line game(MMORPG). Based on 82 behavior statements, 6 types of on-line game lifestyle were found : Self -Enhancer, Self -Expressionist, Relation-Oriented, Isolation -Antisocial, Social Contributor, and Self-Interest. The behavior patterns of the 6 types were then compared to identify similarities and differences amongst them in psychological meanings and values in the on-line game life. The results showed that the lifestyles in on-line game world encompass both the reflection of the lifestyles in the real world and also the creation of new life patterns that players desire. The process of developing lifestyles in the online game world illustrates the emergence and evolution of human life on new social environment which is established by digital technology. On-line game world can be defined as new life space in which people is able to create new identity and new culture.
