This paper is concerned with figuring out a scheme to facilitate UML utilization through examining the factors which affect the intention to use UML. For this, we conducted a survey of those factors among software engineers in IT service companies. In order to examine the factors affecting the intention to use UML, we developed a model by combining the Technology Acceptance Model and the Innovation Attributes Theory, which have been proved to explain well about the acceptance of new technologies and services. Statistical analysis shows that the subjective norm which is one of social factors has significant influence on the career consequences, and also on the compatibility when the result of UML utilization is demonstrable. The career consequences, the compatibility and the ease of use are found to have significant influence on the usefulness perception of UML utilization, implying that the recognition that one's future career can be affected in the long term by UML utilization is important in shaping how one perceives the usefulness along with the compatibility with one's current task type and the ease of use. The usefulness and the compatibility are evaluated to be the factors that have significant influences on the intention to use UML.

본 연구의 목적은 K-MOOC 활용에 대한 만족도 및 지속이용의도에 영향을 미치는 요인이 무엇인지를 분석하는 것으로, 이를 위해 실제 K-MOOC을 비교과 교육과정으로 활용하는 수도권의 한 대학을 대상으로 사례 연구를 실시하였다. 총 177명의 학생들이 참여하였으며, 지각된 유용성, 지각된 용이성, 학습동기, 자기주도성, 과제기술적합성의 다섯 가지 요인을 분석하였다. 연구 결과 K-MOOC 만족도 및 이용에 대한 학생들의 인식은 방학보다 학기 중이 더 높았다. K-MOOC 만족도에 영향을 미친 요인은 지각된 용이성과 유용성, 과제기술 적합성이었으며, 지속이용의도에 영향을 미친 요인은 지각된 용이성과 과제기술적합성이었다. 이러한 연구 결과를 토대로 대학에서의 K-MOOC 활용률을 높이기 위해서는 전공 및 교양지식을 향상시키는데 유용한 교과목을 다양하게 개발하는 것이 필요함을 제안하였다. 그리고 개설되는 교과목과 더불어 교과내용의 분량과 주차수를 보다 다양화할 필요가 있으며, 개설시기를 대학의 학기와 맞출 필요가 있음을 제안하였다. 또한 지각된 용이성 요인은 정적인 영향을 주는 요인이기도 하지만 불만 사항으로도 나타나 플랫폼의 안정성이나 모바일 환경에의 적합성 등이 개선될 필요가 있으며, 대학 수준에 적합한 콘텐츠 개발과 학생과의 상호작용을 다양화해야 함을 제안하였다.

가변 메카니즘은 키오스크를 이용하는 사용자의 키와 위치를 초음파 센서를 통하여 감지하고, 이를 통하여 적정한 높이와 키오스크의 방향을 조절한다. 본 논문에서는 가변형 키오스크의 높이와 방향 제어를 위하여 ADALINE-퍼지 논리 시스템 제어 방식을 제안한다. 제안한 방식의 유용성을 확인하기 위하여 가변형 키오스크 시스템이 사용자의 방향과 높이에 따른 제어 동작을 제대로 수행하는지 대하여 Widrow-Hoff 델타 규칙과 실험을 통하여 성능을 비교 검토 하였다.

This paper identifies the mechanisms governing the industrial location changes in Korea by focusing upon the emergence of the country's large conglomerate business organizations (chaebols). As the country has distinctive industrial organization, production systems, and government-business relations, this study tries to develop an ideal conceptual framework for the analysis of industrial location changes in Korea. It perceives the Korean economy as a system within which 'space-organizing', lage business organizations interact over time with government, smaller firms and multinational corporations at different geographical scales. The usefulness of the model is assessed using a case study of Korea's most representative chaebol, the Samsung Group. This study identifies chaebols as the dominant institutions in Korean society. Their growth and business strategies have been influenced by the Korean Government through its power to allocate capital resources. Regional dynamics of industry and labor, therfore, have been strongly influenced by changes in the location, industrial structure, and production system of chaebols. With econmic power concentrated within a few giant business groups and their major areas of operation restricted, unbalanced regional development has resulted. Dissatisfaction from residents in less-developed areas has pressured the Government to advise chaebols to disperse their production facilities. Most small and medium-sized firms are closely linked to large corporations through subcontracting. By forming hierarchical subcontracting. By forming hierarchical subcontracting systems, chaebols have indirectly exploited scattered, part-time, home-based, female and lower-paid laborers organized by subcontractors. Further, chaebols have expanded their business arena to encompass overseas locations in a bid to overcome the problem of a small domestic market, trade regulations and increased market, trade regulations and increased labor costs. Through their international business networks Korea's local and regional economies are integrated into the world economy. Indeed, the identification of the changing relationships of chaebols with both the Korean Government and smaller firms is the key to explaining the nations's spatial dyanmics of industry and labor.
