운전 중 휴대전화의 사용은 교통사고 유발의 주요한 원인이며 운전자들은 운전 중 안전한 휴대전화 이용을 위해 핸즈프리, 블루투스 등의 다양한 방법을 이용해왔다. 하지만 이 방법들은 직접적인 접촉을 한번 이상 요구하기 때문에 이 과정에서 운전자의 주의 집중이 흐트러질 소지가 있다. 본 연구에서는 운전 중 안전한 스마트폰 사용을 위하여 전자기기에서 광범위하게 적용이 증가하고 있는 모션인식에 기반한 모션 디자인을 제안한다. 먼저 대상 모션을 선정하기 위하여 운전 중 발생할 가능성이 많은 모션을 정의하여 설문 조사를 시행하고, 설문 결과를 바탕으로 5 가지의 모션을 선정하였다. 다음으로, 선정된 모션에 대하여 모션과 그 모션의 동작 수행이 연관성을 가지도록 디자인하고, 이를 위한 기술적 고려 사항을 제시하였으며, 마지막으로 이들 모션에 대하여 사용자의 편의성과 기억의 용이성을 실험적으로 검증하였다. 실험 결과, 제시한 모션 디자인은 기억의 용이성 부분에서 적절한 결과를 보였으며 모션과 행위의 연계성과 편의성에 대하여도 긍정적인 평가를 이끌어냈다. 이러한 결과는 향후 구현되는 모션 디자인의 방향을 제시할 수 있으리라 기대된다.

Recently it is supposed to be a shift to regional geography. To understand the emergence of the new regional geography, It must be remarked that the progress of capitalist production and consumption change our conceptional apparatus such as representation of space. Region is one of the important mode of representations of space and time. In the Fordist capitalism of 20th century, development is regarded as diffusion of capitalist expansion of western worlds. State must support capitalist growth through regional policies which include constructing of infrastructure and regionalization of spatial division of labour. The regional development theories contributed as ideology and policy tools for state intervention. The region was simply one of the most logical classification tools of organizing geographical informations. In the theories of regional development, the concept of region was reduced to the formal unit of classification. As the transition from Fordism to flexible accumulation, the region is again acquiring its 'identity' and 'authenticity'. In this tendency of the revival of region, it is expected that good achievement could be made in the field of regional geography through relevant research methods. It is also believed one of the available means are historical approaches to the cultural and ecological regions. The historical approaches to cultural and ecological regions are not only correspondent with cultural development strategies of local governments, but also could convey regional identities through both narrativization of place and aestheticization of landscape.

Kaplan(2000) reported that instances were categorized more accurate in the aligned condition than in the non-aligned condition irrespective of similarity between instances[16]. This study investigated wether Kaplan(2000)\\`s results could be explained by stimulus types she used and alignment effects in categorization were due to selective attention to aligned attributes. In Experiment 1. I examined whether attribute alignment produced significant effects on similarity and categorization and aligned attributes were recalled more than non-aligned ones. Results showed that instances were rated more similar and categories were learned more rapidly in the aligned condition than in the non-aligned condition. It can be explained that categories are learned rapidly in the aligned condition because attribute alignment increases within-category similarity. But. the result that aligned attributes were recalled more than non-aliened ones in the attribute recall test implies that alignment effects in categorization can be independent of similarity between instances partially. In Experiment 2. I used equal numbed of attributes defining two categories and instructed subjects to pay their attention to categorization-relevant dimensions only. Results showed that dimension instruction facilitated category learning in the non-aligned condition only but categories were learned more rapidly in the aligned condition than in the non-aliened condition irrespective of instruction types. In conclusion. attribute alignment in categorization may facilitate paying selective attention to categorization-relevant attributes.

Buyers' Trust in suppliers is critical in all commerce, but particularly in the relationship between foreign provider and local consumer due to the liability of foreignness. This study examines (1)how local consumers trust in the product of MNCs is affected by their perceptions of the product attributes, (2)does the product trust affects customers loyalty, and (3)whether Global Corporate Citizenship moderates the relationship between the product attributes and trust. Based on previous researches, hypotheses are formulated and the statistical method used to test them was a moderated regression analysis using SPSS 20. 330 respondents from the university student group in Korea were used for this analysis. The results of this study are follows: Service communication and product perceptions such as quality, technological newness, design, and brand value have a significant effect on the product trust. The Effectiveness of product-related service communication had greater than that of the physical characteristics of product. But, price fairness is not significantly. The trust then has a positive relation to customers loyalty. When global corporate citizenship as the moderating role is introduced into the model, the interaction terms with 'price fairness' are verified to be significant. Therefore, global corporate citizenship moderates the relationship between price fairness and product trust. The results of the empirical study provide important implications for Korean firms operating in foreign markets. But, the findings are limited to the University students and to manufacturing sectors. Thus, the generalization of the results of this research remains limited.

This article analyzes the latest cases of Digital Social Innovation such as crowdsourcing and online petitions for public trouble-shooting in oder to demonstrate that public engagement of the citizens on decision making can enhance the quality of democracy. Digital Social Innovation contributes to citizen's participation on decision making and policy implementation with taking advantage of digital technologies of crowdsourcing and online petitions. Active civic engagement for decision making literally helps to improve and democratize government policy. These series of processes not only improve quality and efficiency of policy governance by building up transparency and effectiveness of policy itself but also enhance the throughput legitimacy. With this article, I quote and analyze various practices of Digital Social Innovation which we had substantiated to demonstrate the effectiveness of civic engagement for decision making to improve and enhance democracy. The hypothesis that the Digital Social Innovation attempted in various ways is a principal factor of democratization could be verified. Moreover, the practices of Digital Social Innovation helps the civic participation in policy making in modern society. Finally, this article suggests an implication of Digital Social Innovation as part of efforts to ensure the involvement of throughput legitimacy for the development of democracy.

This thesis has an intention to reorganize the topic of Ontology that has not unnoticed, investigating the symbolic signs of Zhuxi. The symbols in Ontology visualize in an anthropomorphic form or a form of animals that we can usually find in the nature. The visible symbols have characteristics of the dynamic rather than the stillness. The symbols of human and a horse have developed as different interpretations depending on the relative importance. The movement of stream symbolize the Movement of Daoti that manifests thorough all things in the Dao and have a structure of 'Ti-Xiang-Yong'. The Substance of Metaphysics embodies an action thorough 'Metaphysics' or 'with Metaphysics'. Accordingly, 'a stream' symbolizes 'the Movement of Daoti' in that it manifests the form of Daoti makes body. A kite and a fish symbolize the form of a kite flies up into the sky and the shape of a fish plays in the pond. These not only represent an outlook on the world, but also symbolize the stage of the Movement of Daoti. 'Human', 'a stream', 'a kite' and 'a fish' include activeness, domination, dynamics, manifestation, visibility, naturalness.

Due to their geographic proximity to Beijing, the Southeast Asian states under the fallout of the China's growing power are struggling to seek the art of diplomacy to promote their national interests. This study explores why Cambodia previously taking a pro-US strategy after the end of the Cold War has switched to a pro-China one in the context of the rise of G-2 system, the ASEAN regionalism, the country's national interest and Hun Sen's regime legitimation. Theoretically, this study takes a realist constructivist approach and tries to find how realist interests and norms have affected the Hun Sen's regime legitimation. The relationship between China and Cambodia has been deepened by mutual economic interdependence and increasingly stronger Chinese power. Especially, the Chinese massive economic aids and investment have enormously supported the regime legitimation of Hun Sen. On the other hand, The US value diplomacy promoting democracy and human rights has undermined the Hun Sen's legitimacy and strained the two nations' relationship. However, the Hun Sen's pro-China strategy is not to check and balance against US strategic interests and not to recognize the Chinese hegemonic position in Southeast Asia. It is a hedging against the US value diplomacy while maximizing economic and other gains from China. ASEAN has been playing a coordinating role to limit the scope of power politics among big powers and to mitigate its ramifications. Yet, since the US and Chinese interests are so keenly criss-crossing, Cambodia may continue to react to the G-2 system through bilateral relations with them.
