This study tried to explore the ways to operate service learning more effectively by analyzing the educational effects of service learning and changes in learning sentiments that appeared in the service learning operation process established for the realization of the Christian educational philosophy at a small local Christian university. The analysis was conducted using NVivo11, focusing on the reflection journals of students who participated in service learning in the first semester of 2022 at J University. As a result of the study, through service learning, personal competence growth, self-reflection and will to change, self-esteem and self-efficacy, social and civic aspects, social responsibility enhancement, community (community) empathy and awareness of participation, and helping others There were educational effects such as an increase in the breadth of understanding. In addition, learning emotions that appeared in the service learning process included positive emotions such as gratitude, challenge recognition, pride, confidence, and responsibility, and negative emotions such as worry (difficulty), upset, regret, and awkwardness. It is a measure to increase the educational effect based on the learning emotion shown in the service learning process. When operating service learning, the service period at the visiting institution is increased to 6 weeks or more, and based on close interaction and detailed analysis of the educational environment in the planning stage, Suggest to develop and operate a plan. In addition, if you have the opportunity to receive feedback from your professors and colleagues through demonstrations and mock presentations in the classroom before visiting the institution, and finally have the opportunity to visit the institution again after the results of service learning are announced, more quality service learning education will be operated. Based on the results of this study, it is expected that more valuable and meaningful service learning education opportunities will be provided to learners by designing and operating a practical and sophisticated service learning curriculum.

김현우,김승인,Kim, Hyun-Woo,Kim, Seung-In 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.7

본 연구는 OTT(Over-the-top) 서비스의 개인 맞춤형 콘텐츠와 미리보기를 사용자 경험 중심으로 분석하고, 이를 통해 미리보기 시청 경험의 발전 방향을 제안하는 데 목적이 있다. 이에 국내 운영 중인 OTT 서비스의 모바일 애플리케이션을 중심으로 콘텐츠 제공 현황을 파악하였다. 또한, 주 사용자인 20-30대를 모집하여 스티븐 앤더슨(Stephen P. Anderson)의 Creating Pleasurable Interface 모형을 토대로 작성한 질문을 통해 설문조사 및 심층 인터뷰를 진행하였다. 실험 결과, 미리보기는 콘텐츠 선택에 도움이 되지만 취향에 맞지 않았으며, 원하는 대로 시청하기 어려워 불편해하였다. 따라서 개선 방향으로는 미리보기 시청의 효율성, 취향성 및 접근성 향상을 위한 기능이 요구된다. 본 연구는 OTT 콘텐츠의 사용자 경험이나 미리보기 시청 경험에 관한 연구의 자료로써 활용되기를 기대한다. The purpose of this study is to analyze personalized contents and previews of OTT service based on user experience and to suggest the improvements of the preview viewing experience. Current domestic OTT mobile applications were researched to find out how services are offering content. Plus, the 20s-30s were recruited to analyze user experience. An online survey and in-depth interview were conducted by using Stephen P. Anderson's Creating Pleasurable Interface Model. As a result, preview help users to select content but it doesn't suit their taste. Also, the preview is hard to watch however they want. Therefore, it can be inferred that the preview requires the function for improving efficiency, preference, and accessibility. This study is expected to be used as research material on user experience or preview experience of OTT content.

폐경기 증후군의 사회심리적 측면

김현우,Kim, Hyun-Woo 한국정신신체의학회 1996 정신신체의학 Vol.4 No.1

Regarding menopause as a turning point in woman's lift, the author reviewed the psychosocial aspects of menopause. Seeing menstruation as the symbolic meaning of female sexuality, psychoanalysts argue that menopause, the loss of symbolic meaning of female sexuality, may bring a mourning reaction to woman. It is reported that the high ratio of depression does not have a serious relationship with the menopause syndrome, and that depression cannot be viewed as a different symptoms. It is also proved that most women successfully recover themselves from temporary menopause symptom. Research data shows that some women have a negative thought on the meaning of menopause. Others, however, have a positive concept on the meaning of menopause because of the feeling of release and freedom. In sum, the author suggests that psychosocial consideration is very important as much as bilogical consideration in considering the meaning of menopausal syndrome.

We report the production of SiO$_x$ nanowires by thermal heating of Pd-coated Si substrates. Scanning electron microscope images indicated that the nanowires had diameters in the range of 15 -- 100 nm. X-ray diffraction, selected area electron diffraction, and energy dispersive X-ray analyses revealed that the nanowires were amorphous and comprised of silicon oxide only. Photoluminescence measurements showed that the SiO$_x$ nanowires had an emission band in the blue region. We discuss a possible growth mechanism for the SiO$_x$ nanowires.

The purpose of this study was designed to help the operation of the hospital organization through analysis of factors influencing organizational commitment of general hospital nurses. 129 nurses in general hospitals were targeted in G City. This study was conducted to analyze the effects of group efficacy, self-efficacy, and nursing professionals on organizational commitment. T-test, ANOVA, Pearson's correlation coefficient, Descriptive statistics and multiple regression were used. Stepwise regression analysis found that organizational commitment was affected by group efficacy(β=0.240, p =.003), nursing professionalism(β=0.229, p =.004) and daytime work(β=0.249, p =.003), The F statistic was 10.478 (p <.001). Therefore, in order to improve organizational commitment, it will be necessary to prepare communication programs and cooperation programs per unit to improve collective efficacy. In addition, it is necessary to improve the system, such as a system dedicated to night workers, so that the working hours of nurses in general hospitals can be maintained constant. In addition, it is necessary to develop a support program so that nursing professionals do not decrease due to disappointment in reality in the nursing field.

We reported an approach, in which we have produced the nano-sized crystalline tin oxide (SnO2) particles with rutile structure. SnO2 nanowires were coated with a shell layer of SiOx via a sputtering method. Transmission electron microscopy and elemental mapping investigations revealed that the nanostructures consisted of a crystalline SnO2 core surrounded by an amorphous SiOx sheath. The annealing effects on the core-shell nanowires were investigated, revealing that the outer surface became rougher by the thermal annealing. For core-shell nanowires, a room-temperature PL measurement with a Gaussian fitting showed yellow, blue, and violet light emission bands, with the relative intensity of the yellow band showing an increase after thermal annealing. Possible PL emission mechanisms are discussed. This study reveals that the sputtering is effective for preparing the shell layers of nanocables.

This study is about e-Book program based on human-computer interaction(HCI) system for physically handicapped person. By acquiring background knowledge of HCI, we know that if we use vision-based interface we can replace current computer input devices by extracting any characteristic point and tracing it. We decided betweeneyes as a characteristic point by analyzing facial input image using webcam. But because of three-dimensional structure of glasses, the person who is wearing glasses wasn't suitable for tracing between-eyes. So we changed characteristic point to the bridge of the nose after detecting between-eyes. By using this technique, we could trace rotation of head in real-time regardless of glasses. To test this program's usefulness, we conducted an experiment to analyze the test result on actual application. Consequently, we got 96.5% rate of success for controlling e-Book under proper condition by analyzing the test result of 20 subjects.

광학활성 동축 이중층 원통에 수직 입사하는 전자기 파동의 산란을 수치 계산 법을 써서 살펴 보았다. 앞의 논문에서 얻은 해석적인 해를 바탕으로 수치계산 프로그램을 개발했고, 산란광의 밝기와 편광 상태의 각도에 따른 분포를 몇 가지 예에 대해서 계산하였다. 이러한 수치계산 프로그램은 산란광의 밝기와 편광상태의 각분포를 재어 원통의 크기, 구조, 조성을 비파괴적으로 정확히 결정하는데 쓸 수 있다. The scattering of a normally incident monochromatic light by optically active concentric double cylinders is studied by using a numerical method. A numerical code is developed on the basis of the analytical solutions, and the angular distributions of the intensity and the polarization of the scattered light are computed for some specific cases. The numerical code can be used to non-invasively determine the size, structure, and composition of a double cylinder with high accuracy by measuring the angular distribution of the scattered light by an experiment.

소기업 경쟁전략과 CEO 리더십 유형이 기업성과에 미치는 영향

김현우,Kim, Hyun-Woo 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.6

본 연구는 우리나라 소기업의 경쟁전략이 CEO의 리더십 역할에 따라 어떻게 기업성과에 영향을 끼치고 있는지를 고찰하였다. 소기업의 경쟁전략은 기업의 전략적인 의사결정에 절대적인 영향을 끼치고 있어 이를 실증 분석하는 것을 목적으로 한다. CEO 리더십 유형을 구분하여 경쟁전략과 기업성과와의 영향 관계를 탐색하기 위해 국내 소기업을 대상으로 설문조사를 통해 자료를 수집하여 위계적 조절회귀 분석을 통해 실증하였다. 본 연구의 주요 연구결과는 다음과 같다. 첫째, 소기업의 경쟁전략은 차별화 전략과 원가우위 전략의 유형과 관계없이 모두 소기업 성과에 영향을 끼치고 있는 것으로 나타났다. 특히 전략유형 보다는 일관된 전략추구가 기업성과에 더 긍정적인 것으로 나타났다. 둘째, 소기업이 추구하는 전략 유형에 따라 CEO의 리더십 유형도 달라져야 함을 확인하였다. 구체적으로 차별화 전략의 경우 변혁적 리더십이, 원가우위 전략에는 거래적 리더십이 적합한 것으로 나타났다. 이상의 연구결과를 통해 소기업의 경쟁전략은 전략유형보다는 일관된 전략추구가 생존과 직결되어 있어 더욱 중요하며, 소기업의 CEO는 경쟁전략에 따라 적합한 리더십 스타일을 추구해야 할 것으로 사료된다. This paper investigated the role of CEO leadership in the relationship between Korean small firm's competitive strategy and performance. This study conducted an empirical analysis by collecting data through a questionnaire survey targeting small firms in Korea. The main findings of this study are as follows. First, it was found that the competitive strategies of small firms all had a positive effect on the performance, and it was found that a strategic consistency rather than the type of strategy was positive for firm performance. Second, it was found that the type of leadership of the CEO should also be changed according to the type of strategy. Specifically, it was found that transformational leadership was more appropriate for differentiation strategies, and transactional leadership was more appropriate for cost advantage strategies. This study clarified that the pursuit of a strategic consistency is more important than the type of strategy in the competitive strategy, and that the CEO needs to pursue an appropriate leadership style according to the competitive strategy.
