Solar power facilities to reduce carbon emissions are continuously being installed in forests, farmland, city, and on water. However, research on visual preferences and the psychological impact on observers after installing solar power facilities is insufficient. Therefore, in this study, shooting was conducted according to the viewing distance of the near, middle, and distant views of Hapcheon Dam, Korea's largest floating photovoltaic power plant. The acquired images were edited using Photoshop to compare the presence or absence of floating photovoltaic power generation facilities. In addition, psychological changes and visual preferences were analyzed through an EEG test and questionnaire among 50 participants. The results are summarized, as follows. First, the installation of water photovoltaic power generation facilities has a passive impact on the subjects' psychological changes and visual preference. Second, the psychological changes due to the installation of water photovoltaic power generation facilities were judged to affect almost all research subjects, regardless of nationality, gender, or universisty major. Third, the visual preference for installing the water photovoltaic power generation facility is low, which can be interpreted as the water photovoltaic power generation facility negatively affecting the "friendliness" and "naturalness" of the landscape. In addition, this change in visual preference was found to differ depending on the gender and universiity major of the subjects. Fourth, the psychological change and visual preference of the floating photovoltaic power generation facility according to the viewing distance, found that the close range had a higher effect than the middle and distant ranges.

The purpose of this study is to investigate the academic librarians' perception of the current status and establishment of the development plans of domestic university libraries to suggest ways to increase usefulness of development plans. And this study sought ways to establish the academic library development plan that reflected the key components of the development plan. To this end, a survey was conducted on academic library librarians, and in-depth interviews were conducted with the persons in charge of the academic library development plan to supplement the limitations of survey. The results are as follows. First, the establishment of academic library development plans tend to be formal and passive, and has limitation in eliciting cooperation between external organizations and academic libraries. Second, most academic libraries do not disclose their development plans on their websites. Third, the awareness of the leaders of the academic library organization needs to be preceded, and a task force needs to be formed to establish development plan. As a result of the study, it is suggested that 'active changes in the perceptions and operation method within academic libraries', 'external disclosure of development plans and strengthening cooperation', and 'strengthening the initiative and role of librarians' are needed as improvement measures.

In order to determine the level of awareness of nuclear power generation and Fukushima contaminated water, this study conducted an online survey targeting the general public living in the Busan area and analyzed a total of 201 questionnaires. Independent samples t-test and one-way analysis of variance were conducted to verify differences in variables according to the characteristics of the study subjects, and correlation analysis was conducted to confirm the correlation between variables. First, the results of the study showed that women had a more negative perception of nuclear power generation and Fukushima contaminated water than men. In terms of age, it was found that people in their 40s and older had a high level of negative perception. In terms of political inclination, progressive respondents showed a higher negative perception toward nuclear power generation and Fukushima contaminated water. Second, information on nuclear energy was most often collected through the Internet, broadcasting, and SNS. Third, the higher the negative perception of nuclear power generation, the more negative the results were in terms of issues of concern following the discharge of contaminated water at the Fukushima nuclear power plant. Nuclear power cannot be separated from human life. Therefore, it is believed that accurate information and a knowledge delivery system are needed to ensure correct awareness of nuclear power generation.

본 연구의 목적은 국경 간 전자상거래 플랫폼의 지속이용의도의 영향을 파악하며 국경 간 전자상거래 플랫폼의 발전에 의의를 규명할 것이다. 국내 전자상거래에 비해, 국경 간 전자상거래는 문화 차이, 언어 차이, 법률 차이, 통관 처리, 국경 간 물류 등의 문제로 인해 더 높은 불확실성을 가지고 있다. 소비자의 지속이용의도에 관한 연구는 국내 전자상거래의 연구에 머물러, 국경 간 전자상거래 플랫폼이 많은 도전에 직면하게 된다. 국경 간 전자상거래 플랫폼의 어떤 요인이 소비자의 구매 의도에 영향을 미치는지 연구하면, 국경 간 전자상거래 기업의 플랫폼에 상응하는 개선을 돕고, 국경 간 전자상거래 기업의 발전을 촉진하며, 이를 통해 대외무역의 발전을 촉진 할 것이다. 특히 한국 중소업체 입장에서는 이를 통해 한국 제품을 직접 수출의 주역으로 자리 잡으며 육박하는 수출을 견인한 것으로 추정될 수 있다.

본 현대사회는 문명적, 기술적, 산업적으로 발전함에 따라 그에 상응하는 절도, 폭행, 살인 등 중대범죄의 범위를 벗어나 이념과 국가, 종교, 등 가치관과 사상에 따른 테러 사건 등 국제적인 범죄도 증가하고 있는 추세이며, 국제사회는 중대범죄 및 전쟁의 공포보다 예측 불가능, 막대한 대량 피해를 불러오는 테러에 의한 공포심을 더 비중 있게 대하는 현실에 직면했다. 테러범죄는 개인을 넘어 다중에게 피해를 입힐 수 있는 범죄인만큼 대중에게 경각심과 위험성을 알리기 위해선 구체적이고 손쉽게 이해할 수 있는 명확성이 필요하다. 테러는 수년간 다양한 방식과 개념들이 증식했으며 피해 또한 더 이상 소규모인원, 특정인을 향한 계획적인 범행에서 불특정 다수를 향한 뉴테러리즘식의 테러로 발전하고 있어 안보의 개념에도 영향을 미치고 있다. 따라서 대한민국 역시 언제까지나 테러의 위험성으로부터 안전을 확신할 수 없기 때문에 국내 정서에 맞는 테러 대응방안과 시스템 구축을 통해 뉴테러리즘의 발생 가능성을 염두 하고 대비할 필요가있다.

Due to the development of the domestic economy and science, the people's standard of living has increased. Accordingly, we want to improve the quality of life. In other words, we guarantee human rights and pursue dignity and value as human beings. Therefore, the medical field extends human life and helps maintain a healthy life. The social medicine that protects human rights is forensic medicine. Forensic medicine identifies deaths and analyzes the cause using forensic radiology images. Forensic radiology is the acquisition and provision of medical images by the radiographer. Therefore, the radiographer must have expertise by completing forensic science-related courses. Recently, medical and nursing schools have opened and operated various subjects such as forensic medicine and forensic nursing. However, the Department of Radiology science is the only school that offers courses related to forensic science. For the future development and exploration of the radiographer and department of radiology science, forensic education should be considered. For this purpose, we investigated the necessity and demand for forensic education in the department of radiology science undergraduate and graduate schools. The department of radiology science students' awareness of forensic science was found to be 2.977 points, but the need for forensic science education for the radiographer was high at 3.759 points. In addition, current students' demand for forensic science courses was high at 84.1%, with the majority responding that it was necessary to open and operate the course. This study was able to determine the demand for forensic science-related subjects among the department of radiology science undergraduate and graduate students, and there is a need to explore diversity and expertise in education. We hope that it will be used as basic data for the development of forensic medicine and radiology science.

In order to analyze the degree of self-learning development ability after the clinical training curriculum, the results of 121 questionnaires were analyzed for 3rd and 4th grade students in radiology in the metropolitan area. The overall average of self-learning ability according to gender was $3.07{\pm}0.85$, which was statistically significant according to gender. However, the results according to educational system showed that the overall average was $3.07{\pm}0.85$, which was higher than the average level of self-learning development ability. There was no statistically significant difference according to educational system. The results of the self-learning development ability according to the motivation for selecting the department showed that the students who have chosen their department due to their higher employment rate after graduation had high self-development ability level($3.58{\pm}0.85$) but the students who entered the school due to self-aptitude had relatively lower self-development ability level ($2.30{\pm}0.40$). The overall average of self-learning ability according to direction of career path was $3.08{\pm}0.76$, which was over-average of self-learning development ability. Thus, there was statistically significant difference according to career path. It is necessary to improve the self-learning ability in clinical practice. In addition, the lack of statistical significance suggests problems and diversity.
