일반화 대칭 변환 (generalized symmetry transform, GST)은 주어진 영상에서 사전 분할이 없이 국부성과 반사 대칭성을 결합하여 대칭을 측정하고 관심 영역을 추출한다. GST의 거리 가중치 함수에서 국부적인 대칭성이 반영되며 이 함수의 표준 편차 u에 의해 GST의 수행 범위가 조절된다. 넓은 관심영역을 추출하기 위해 반지름 r이 큰 검색영역 내에서의 대칭성이 추출될 필요가 있다. 이에 따라서 GST의 수행시간은 r에 따라 2차적으로 증가하게 된 본 논문에서는 이를 개선하기 위해 선택적 방향 주의를 가지는 수정된 스캔라인 GST를 제안한다. 제안된 GST는 기존의 GST와 유사한 대칭 특성을 추출하지만 선택적 방향의 기울기만을 고려한 스캔라인 위의 에지 화소쌍에서 GST를 수행함으로써 r에 따라서 이의 수행시간이 선형적으로 증가된다 특히 r이 큰 경우에 선택적 방향에 대해서만 적용하면 기존의 GST의 계산량이 비대해지는 단점을 보완해 줄 수 있다. 제안된 GST가 기존의 GST보다 시간적으로 효과적이며 유용하다는 것이 여러 종류의 영상에 대한 실험으로 확인되었다.

IT 산업의 발달에 따른 기술의 변화로 인해 사용자들은 유/무선 단말기를 이용하여 여러 가지 서비스를 제공 받을수 있을 정도로 IT 인프라가 발전하였다. 이러한 IT 발전은 전자 정부 구축에 대해 더욱 가속화 시키고 있으며, 민원 업무와 관공서의 업무가 인터넷을 통한 서비스로 국민에게 제공되어 편리성과 효율성을 높이고 있다. 전자 정부 서비스는 민원 서비스뿐만 아니라 민주주의 기반이 되는 대표자 선출의 투표에 대해서도 전자적인 서비스를 제공하여야 한다. 투표는 국민의 민주주의 의사가 방영되는 가장 기초적의 방식으로써 투표에 있어 전자 시스템을 도입하여 유권자의 편리성을 제공하고 투표 시스템의 효율성을 높이는 것이 전자 투표 시스템이다. 전자 투표 시스템은 국민의 의사를 방영하는 것으로 안전하게 투표의 과정이 이루어져야한다. 그러므로 본고에서는 전자 투표에서 적용되는 보안 기술 및 종이 영수증 기술에 대하여 알아보고 향후 연구 방향에 대해서 논의한다.

운전 중에 주의를 분산시키는 요소는 대부분 인터페이스 조작에 있으며 교통사고의 직접적인 원인이 된다. 스마트 자동차에 대한 관심이 높아지면서 운전자 안전에 대한 다양한 연구가 모색되고 있다. 순간의 시선이동으로 인해 판단력과 조작능력을 상실 할 수 있는 현재의 인터페이스는 안전성이 보장 되지 못한다. 본 논문에서는 이러한 운전자의 주의를 분산시키는 요소로 부터 안전성을 확보하기 위해서 차량 내 카메라를 이용하여 손동작을 인식하여 직관적인 제스처로 전화번호를 입력하거나 검색할 수 있는 안전한 인터페이스를 제안한다. 제안한 시스템은 직관적 동작과 TTS(Text To Speech)를 활용하여 사용자 편의성과 안전성을 높였다.

While strategic alliance of multinational corporation has boost, opportunistic behavior is also increased recently. This study examines the cause of opportunism in strategic alliance by focusing on the development of opportunistic behavior, a process in which resource complementarity and risk perception decides attitudinal direction, ultimately leading to opportunism. Empirical test based on 257 alliance participants shows that risk perception had a greater influence on firms' attitudinal and behavioral directions compared to benefit perception. Notably, relational risk heavily influenced firms' competitive attitude and opportunistic behavior. Finally, the study concludes that firms' competitive and independent attitude caused by risk perception negatively influence alliance outcome. Based on the results, it is drawn that alongside the external tools such as surveillance, control, monitoring or legalistic pleas, management of risk perception during the alliance process has significance influence on the achievement of alliance goals.

The study aims to verify the effects of volleyball programs on the fitness and attention-intensive abilities of students with intellectual disabilities in middle school. Physical strength and attention concentration were analyzed to verify the effectiveness of the volleyball program. The volleyball program was applied to the experimental group three times a week, 90 minutes a week, a total of 36 times for 12 weeks. To verify the effectiveness of physical strength and attention concentration, the PPS-D intellectual disability student test and ATA concentration test were used to verify the effectiveness of attention concentration The six-minute walking figure related to cardiopulmonary functions was improved compared to those with intellectual disabilities who did not participate in the volleyball program, the report showed. We can see improvements in muscular function-related sit-ups and flexibility-related sit-ups compared to those with intellectual disabilities who did not participate, and significant changes have been seen in the distance of the place-wide jump related to net worth. We could also confirm that it had a positive effect on the improvement of selective attention concentration, and that the change in self-control, continuous attention, and selective attention among middle school students had a positive effect on the improvement.

This paper critically examines the existing discourses about 'relationship', a key element of social work practice and questingly examines Lao-tzu's work of Tao Te Ching, the book of way and virtue, as an alternative theoretical framework for social work relationship. Compared to current discourses of relationship beleaguered by either modernism or postmodernism, both of which are in the deadlock of binary perspective, the insights and vision in Tao Te Ching are successfully able to overcome the limits of them and provide new and profound way of thinking about human, society and their relationship. Especially core cannons crystallized by natural humanistic concepts for cosmos coupled with innate critical power against artificial manipulations of world can extend the horizon of understanding concerning the relationship between client and social workers and therefore provide a new and attractive roles in professional relationship. Moreover, opposed to usual images of Lao-tzu's ideas such as nihilism and passivity, alternative relationship of social work can play an important role of caring the disordered reality where Dao disappered and criticise the selfish desires of individuals and comport the broken-hearted minds in modern society. In addition, results of this paper implies that more extended study articulating ideas of Tao Te Ching with the social work practice would have lots of potentials to promote later researches in quest of 'Korean' social work practice.

Given the recent trend in business markets to seek and conscientiously develop long-term relationships, it has become increasingly important to understand why such long-term relationships are developed and how they are maintained. Despite their obvious importance, the antecedent conditions and processes of long-term relationships between industrial buyers and suppliers have not been systematically studied. In this research, I report a study of the antecedents of industrial buyer-seller relationships and the relational performance. What kinds of factors contribute to the development of long-term relationships\ulcorner How do these factors influence the corporate performance in the business markets\ulcorner The primary motivation of this study was drawn from an interest in answering these research questions. Managerial implications of the study results are also discussed.

The purpose of this study is to explore implications for intergenerational Christian education in Korean churches and families that struggle with "generational fragmentations" focusing on the conception of reciprocity and participation. For the faith community in Korea, "generational fragmentations" does not merely mean communication gaps or the disconnection between generations but also the absence of reciprocity and communal participation as a genuine intergenerational community of faith. With this phenomenon in mind, this study explores the concept of "intergenerationality" in education, focusing on reciprocity and participation. Next, this study examines the concepts of reciprocity and participation found in John Dewey's seminal works, Democracy and Education and Experience and Education based on his ideas of democracy and experience in relation to intergenerational Christian education for the Korean church and families. The present paper then attempts to find implications for intergenerational Christian education in the Korean church and family, showing the importance of an intergenerational community of faith with reciprocity and communal participation, and communal spiritual journey with children and adults.

We explore the priority between product attributes such as aesthetics and usability in consumer decision-making. In the recent study in Germany, consumers preferred a visually beautiful product but discounted the value of aesthetics in actual product choice (Diefenbach & Hassenzahl, 2009). In contrast to the individualistic culture which values personal needs(e.g., Germany), recognition from other members has great importance in the collectivistic culture (e.g., Korea). We propose that Korean consumers weigh greater value on the attribute easily perceived from the product appearance (i.e., aesthetics). We replicated the procedure of the study conducted in Germany. As expected, participants highly valued aesthetics rather than usability in product choice. As for aesthetics, participants were likely to choose an expensive but beautiful product; on the contrary a less expensive and less usable product were likely to be chosen as for usability (Study 1). Moreover, usability was sacrificed for aesthetics in the trade-off condition (Study 2). The participants who chose the beautiful product reported higher social recognition desire whereas no difference was shown with respect to usability.
