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.

Background: Radiation is used in a variety of areas, but it also poses potential risks. Although radiation is often used with great effectiveness in many applications, people perceive potential risks associated with radiation and feel anxious about the possibility of radiation exposure. Various methods of measuring radiation doses have been developed, but there is no way for the general public to measure their doses with ease. Currently, many people use smartphones, which provide information about the location of an individual phone through network connections. If a smartphone application could be developed for measuring radiation dosage, it would be a very effective way to measure individuals' radiation doses. Thus, we conducted a survey study to assess the social acceptance of such a technology by the general public and their intent to use that technology to measure radiation doses, as well as to investigate whether such an intention is correlated with anxiety and attitudes toward the use of radiation. Materials and Methods: A nationwide online survey was conducted among 355 Koreans who were 20 years old or older. Results and Discussion: Significant differences were found between the genders in attitudes, perceptions of radiation risk, and fears of exposure to radiation. However, a significant difference according to age was observed only in the intent to use a smartphone dose measurement application. Attitudes towards the use of radiation exerted a negative effect on radiation risk perception and exposure anxiety, whereas attitudes towards the use of radiation, risk perception, and anxiety about exposure were found to have a positive impact on the intent to use a smartphone application for dose measurements. Conclusion: A survey-based study was conducted to investigate how the general public perceives radiation and to examine the acceptability of a smartphone application as a personal dose monitoring device. If such an application is developed, it could be used not only to monitor an individual's dose, but also to contribute to radiation safety information infrastructure by mapping radiation in different areas, which could be utilized as a useful basis for radiation research.
