일제강점기 김옥균의 초상

김현우(Kim, Hyeon-u) 한국양명학회 2018 陽明學 Vol.0 No.49

김옥균은 한국 근대기 비극적 삶을 산 개혁가이다. 그 후 사람들은 김옥균을 자신의 입장에서 묘사하기 시작했다. 신채호는 김옥균의 개화사상을 한국 전통의 대표적인 개혁가인 박규수·박지원과 연결시켰다. 신채호는 한국이 주체적으로 문명을 수입해서 독립할 수 있다는 것을 강조했기 때문이다. 한편, 일본에서는 김옥균을 일본의 메이지유신의 모델로 보고 갑신정변의 당위성을 설파했다. 즉 대륙침략 이론인 대동아공영을 확산시키기 위해 김옥균을 제국주의 일본의 가치관 속에서 해석했던 것이다. 친일파들도 이와 유사하게 김옥균을 일본과 연결시켰다. 그들은 일본의 한국 지배를 정당화하는데 김옥균을 동원했던 것이다. 반면 민족주의자 안재홍은 김옥균의 스승인 유홍기를 불교 신자가 아닌 천주교 신자로 묘사했다. 그는 김옥균 개혁론의 근원을 전통도, 일본도 아닌 보편적 세계사의 관점에서 보았기 때문이다. 이처럼 김옥균의 비극적 삶은 사후 여러 편의 신화로 가공되었다. 그 속에는 식민지 한국에서 진행되는 일본식 문명관에 대한 강한 비판도 있었다. 현대 우리사회는 새로운 문명 즉 “4차 산업”으로 들어가고 있다. 4차 산업혁명시대도 이전 산업혁명과 마찬가지로 인간과 문명 간의 새로운 관계가 정립되어야 할 것이다. 그런 점에서 일제 강점기 문명에 대한 수용과 비판의 산물인 김옥균의 초상들은, 인공지능·초연결사회·사물인터넷·로봇공학 등을 통해 점차 확장되는 4차 산업시대에 있어서, 인간과 문명에 대한 깊은 시사점을 줄 것이다. Kim Ok Gyun is a reformist to have lived a short and tragic life in Korea modern times. And then people began portraying him from a few versions. Shin Chae Ho, who is a representative fighter for Korea independence, matched him to Park Gyu Su and his grandfather, Park Ji Won, were all Korea traditional reformers. Because he intended to conform that Korea could be independent by himself. Japan portrayed that he led Gapsin Coup modeling the Meiji Restoration in Japan. Japan need someone foreign to propagandize and spread out her policy of Greater East Asia Co-Prosperity Sphere. Kim was almost the only foreigner. Pro-Japanese group in Korea, matched him to Japan. Because they tried to justify Japan’s Ruling. But An Jae Hong of a nationalist described that he was influenced by just Catholic of the western not Japan to write his teacher of Yu Hong Gi a Catholic. Kim’s tragic life was treated in myths. They included criticism of civilization to progress in Korea in Japanese Ruling Era. Those were all philosophical considerations on civilization. Meanwhile, we now face a kind of civilization, the Fourth Industry. We need to define the new relation between human and civilization in this time. So, it is still valid for philosophical considerations on civilization which appeared in Korea modern times.

Effect of growth temperature on the ZnO nanowires prepared by thermal heating of Zn powders CLR

김현우,Buddhudu Srinivasa,Doo Young Kim,Jae Young Park,Sang Sub Kim,Mesfin A. Kebede,Hyo Sung Kim 한국물리학회 2010 Current Applied Physics Vol.10 No.1

influence of the growth temperature on the morphology, structure, and photoluminescence (PL) properties of ZnO nanowires has been investigated. At the higher-temperature growth process, thinner nanowires have been obtained. Interestingly, it is observed that the variation of growth temperature has significantly affected the photoluminescence spectra of the ZnO nanowires, showing an enhancement in the relative intensity of the green to UV emission bands with the increase of the growth temperature. In addition, the oxygen sensing properties of the as-synthesized ZnO nanowires were tested.

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.

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,김진승,Kim, Hyun-Woo,Kim, Jin-Seung 한국광학회 2009 한국광학회지 Vol.20 No.6

광학활성 동축 이중 원통의 산란 문제에 대한 해석적인 해를 구하였다. 얻은 해의 타당성을 점검하고자 해를 이미 알고 있는 특수한 경우와 비교하였다. 이 해는 둥근 막대모양의 생물 세포를 광학적으로 분석하는데 쓸 수 있는데, 세포핵에는 나선형으로 꼬인 염색체가 들어 있으므로 광학활성이 있을 수 있다. An analytic solution is obtained for the problem of monochromatic light scattering by optically active, concentric double cylinders. The validity of the obtained solution is indirectly checked by comparing it with solutions already reported for some special cases. The solution can be used in the optical analysis of rod-shaped biological cells which possibly have optically active nuclei containing helically wound chromosomes.

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.

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.

In the present study, the anti-cancer activity of 80% ethanol extracts from 120 kinds of medicinal herbs and native plants were investigated. Among them, the barks of Melia azedarach L. var. japonica Makino showed the highest cytotoxicity in HCT-15 human colon cancer cell. With this result, we carried out hollow fiber (HF) assay and anti-metastasis study to confirm the anti-cancer effects of M. azedarach var. japonica. In MTT assay, M. azedarach var. japonica.inhibited the proliferation of HCT-15 cells in dose-dependent manner. HF assay was carried out using A549 human adenocarcinoma cell, HCT-15 and SK-Hep1 human liver cancer cell via intraperitoneal (IP) and subcutaneous (SC) site. As a results, SK-Hep1 implanted in IP site showed the highest cytotoxicity. The result from metastatic model using B16/BL6 mouse corresponded to that of HF assay. These results suggest that the ethanol extract from M. azedarach var. japonica. might have a potent anti-cancer activity and advanced study is needed for the development of novel natural anti-cancer drug.

Cloud HSM와 edge-DRM Proxy를 활용한 안전한 원격근무 환경 강화 연구

김현우,이준혁,박원형,Kim, Hyunwoo,Lee, Junhyeok,Park, Wonhyung 한국융합보안학회 2021 융합보안 논문지 Vol.21 No.3

현재 코로나-19 팬데믹 현상으로 인해 기업이나 기관에서는 원격근무를 제공하는 상황에서 안전한 근무환경을 구축하기 위해 논리적 망 분리 기술 중 하나인 가상화 데스크톱 기술을 도입하고 있다. 가상화 데스크톱 기술을 도입함에 따라 기업이나 기관에서는 망분리 환경을 보다 안전하고 효과적으로 운영할 수 있게 되었으며, 업무망에 신속하고 안전하게 접근해 업무 효율성과 생산성을 높일 수 있게 되었다. 그러나 가상화 데스크톱 기술을 도입함에 있어, 높은 사양의 서버와 스토리지, 라이선스의 비용적인 문제가 있으며, 운용 및 관리적인 측면에서의 보완이 필요한 실정이다. 이에 대응하기 위한 방안으로 기업이나 기관에서는 클라우드 컴퓨팅 기반의 기술인 가상 데스크톱 서비스(DaaS, Desktop as a Service)로 전환하는 추세이다. 하지만 클라우드 컴퓨팅 기반의 기술인 가상 데스크톱 서비스에서 공동책임모델은 사용자 접근 통제와 데이터 보안은 사용자에게 책임이 있다. 이에 본 논문에서는 가상 데스크톱 서비스 환경에서 공동책임 모델을 근거로, 사용자 접근 통제와 데이터 보안에 대한 개선 방안으로 클라우드 기반 하드웨어 보안 모듈(CloudHSM)과 edge-DRM Proxy를 제안한다. Due to the current COVID-19 pandemic, companies and institutions are introducing virtual desktop technology, one of the logical network separation technologies, to establish a safe working environment in a situation where remote work is provided. With the introduction of virtual desktop technology, companies and institutions can operate the network separation environment more safely and effectively, and can access the business network quickly and safely to increase work efficiency and productivity. However, when introducing virtual desktop technology, there is a cost problem of high-spec server, storage, and license, and it is necessary to supplement in terms of operation and management. As a countermeasure to this, companies and institutions are shifting to cloud computing-based technology, virtual desktop service (DaaS, Desktop as a Service). However, in the virtual desktop service, which is a cloud computing-based technology, the shared responsibility model is responsible for user access control and data security. In this paper, based on the shared responsibility model in the virtual desktop service environment, we propose a cloud-based hardware security module (Cloud HSM) and edge-DRM proxy as an improvement method for user access control and data security.
