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.

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.

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.

김현우,Seung Hyun Shim,Jong Woo Lee,Hyo Sung Kim,Mesfin Abayneh Kebede,나한길,양주찬,공명호,이종무 한국물리학회 2010 Current Applied Physics Vol.10 No.1

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.

벼 유기재배를 하는데 있어서 전층과 표층 시비방법에 따른 토양의 화학성, 물리성, 미생물상, 그리고 벼의 생육과 수량에 대해서 어떠한 영향을 미치는 지를 구명하기 위해서 수행하였다. 2008년부터 2010년까지 3년간에 걸쳐서 전라남도농업기술원 시험포장(논, 양토)에서 조사하였고 시험품종은 '동진1호'를 이용하였다. 토양유기물은 표층시비에서 높았고 토양양이온은 전층시비에서 높았다. 유기질비료의 질소 무기화율은 표층시비에서 높았고 잔존하는 시기별 토양 유기물함량도 표층시비에서 높은 경향을 나타내었다. 토양물리성은 전층시비에 의해서 향상되는 경향을 보였고, 토양 미생물상은 전체적으로 표층시비에서 높았다. 표층시비구가 전층시비보다 5%의 수량이 증수되는 특성을 보였다. This study was investigated to evaluate the effects of fertilizer application of surface and broadcast for rice culture on the soil chemical, physical, and microbial properties as well as growth and yield of rice. The application was made with 'Dongjin 1' rice at Jeollanam-do Agricultural Research & Extension Services from 2008 to 2010. Soil organic matter and cation concentrations were increased by surface and broadcast applications, respectively. Plots treated by surface application tended to be higher seasonal N-mineralization rate in the organic fertilizer and seasonal soil organic matter than those of broadcast application. Soil physical properties seemed to be improved by the broadcast application, and soil microbial properties were increased by the surface application. Surface application increased 5% of rice yield compared to that of broadcast.

편평족은 내측 세로궁이 소실되어 족저부가 편평하게 되는 변형의 총칭으로, 소아에서 흔하 고 보호자들의 관심이 많은 질환이다. 이학적 검사상 후족부의 외반과 전족부의 외전소견을 보이며, 감별질환을 위해 정확한 이학적 검사와 방사선학적 검사를 필요로 한다. 원인으로는 유연성 편평족, 종골 외반, 선천성 수직 거골, 부주상골, 족근골 결합등이 있으며 정상적 유 아의 경우 시간경과에 따라 저절로 호전되는 유연성 편평족이 대부분이다. 따라서 병적 편평족이 아닌 경우 편평족의 원인과 양호한 자연경과를 보호자에게 설명하는 것이 중요하다. 본 논문에서는 소아 편평족의 감별질환을 위한 각 질환에 있어서의 이학적 소견과 검사소견 그리고 이들의 치료에 대해 살펴 보고자 한다.

다중매개모델에서 bootstrapping기법을 이용한 흡수능력의 매개효과 분석

김현우,이홍배,신용호,Kim, Hyun-Woo,Lee, Hong-Bae,Shin, Yong-Ho 한국시뮬레이션학회 2015 한국시뮬레이션학회 논문지 Vol.24 No.4

매개효과 검정기법으로 널리 사용하고 있는 Baron and Kenny 접근법, Sobel, Aroian, Goodman 검정법들의 통계적 검정력이 약할 뿐만 아니라, 정확하지 않다는 비판이 대두되면서, bootstrapping 기법이 대안으로 제시되고 있다. 이에 본 연구는 bootstrapping 기법을 토대로 세 개 이상의 변수로 구성된 다중매개모델에서의 매개효과 검정을 위해 가상의 phantom 변수를 도입하여 검정하였다. 특히, 경영전략분야의 자원기준관점 연구에서 진행되고 있는 조직자원과 매개변수 흡수능력, 그리고 기술사업화역량 관계 모델을 다중매개모델로 설정하여, bootstrapping 접근방법과 phantom 변수 설정을 통해 총간접효과 크기와 유의확률을 계산하고, 흡수능력의 매개효과를 검정하였다. 검정결과 매우 효율적이고, 체계적인 매개효과 검정이 가능하였음을 확인할 수 있었으며, 인적자원과 물적자원의 자원 특성에 따라 흡수능력의 매개 특성도 차이가 있음을 확인하였다. The mediation methods suggested by Baron and Kenny, Sobel, Aroian and Goodman, have widely used to test the mediating effect. However, as there are many problems in statistical test power, as well as statistical accuracy, a bootstrapping technique has been suggested as an alternative. In this paper, we adopt the phantom variables based on the bootstrapping technique to test the mediating effect in multiple mediator model consisting of three or more mediating variables. In particular, we formulate the multiple mediator model for analyzing the relations among organizational resources, the absorption capacity as mediating variables and technology commercialization capabilities. And using the bootstrapping approach, we analyzed the mediating effect of the absorption capacity by setting of phantom variables and calculated total indirect effect size and the statistical significance. The empirical results are as follows. First, we confirmed that the bootstrapping approach and the phantom variable is the very efficient and systematic mediation method. Second, we recognized that there is a difference in the mediating characteristics of the absorption capacity depending on the resource characteristics of human resources and material resources obviously.

김현우,박주용,이정직,윤영로,Kim, Hyun-Woo,Park, Joo-Yong,Lee, Jeong-Jick,Yoon, Young-Ro 대한의용생체공학회 2014 의공학회지 Vol.35 No.2

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.
