        변혁적 리더십이 지식공유에 미치는 영향: 구성원 간 신뢰와 집단응집성의 매개효과

        임대환,김동주 한국경영교육학회 2014 경영교육연구 Vol.29 No.1

        지식공유는 조직 경쟁력 향상을 위한 주요 요소로 알려져 있지만 군 조직 내 지식공유에 긍정적인 영향을 미치는 변수들에 대한 연구는 부족한 실정이며, 주로 지식관리시스템의 활성화 방안을 중심으로 연구되어 왔다. 이에 본 연구에서는 선행연구에 대한 검토결과를 토대로 특전사 부대를 대상으로 변혁적 리더십이 지식공유에 미치는 영향 및 변혁적 리더십과 지식공유 간구성원 간 신뢰와 집단응집성의 매개효과에 대한 연구모형을 설계하여 실증분석을 시도하였다. 분석결과, 변혁적 리더십은 구성원 간 신뢰와 집단응집성, 지식공유 활동에 긍정적인 영향을 미치고 있었으며, 구성원 간 신뢰는 집단응집성과 지식공유에, 집단응집성은 지식공유에 각각 정(+)의 관계에 있는 것으로 나타났다. 또한 구성원 간 신뢰와 집단응집성은 변혁적 리더십과 지식공유 간의 관계를 매개하는 것으로 검증되었다. 끝으로 연구결과의 의의와 시사점에 대하여서도 논의하였다. Even though knowledge sharing is known as an essential factor to strengthen the organizational competitiveness, there has been little research about variables that have positive influences on knowledge sharing in military troops. Studies have been conducted largely on how to promote knowledge management systems. Therefore, this study attempted to analyze the effects of transformational leadership on knowledge sharing and the mediating effects of trust in co-workers and group cohesiveness between transformational leadership and knowledge sharing empirically based on the preceding research. The members of the ROK Special Warfare Forces were selected as the research subjects. The results showed that transformational leadership had a positive impact on trust in co-workers, group cohesiveness and knowledge sharing. Trust in co-workers also had a positive impact on group cohesiveness and knowledge sharing, and group cohesiveness positively influenced knowledge sharing. Also, trust in co-workers and group cohesiveness had mediating effects between transformational leadership and knowledge sharing. Finally, we considered the implications of the study.

        임대환,윤용갑,Lim, Dae-Hwan,Yun, Young-Gab 대한한의학방제학회 2005 大韓韓醫學方劑學會誌 Vol.13 No.2

        This report describes 48 studies related to the use of Bulbus Fritillariae main blended prescriptions from Donguibogam. The following conclusions were reached through investigations on the prescriptions that use Bulbus Fritillariae as a key ingredient. All kinds of infection in a cough and the malignant tumor recorded the largest number of clinical frequency of the prescriptions in therapeutic use when Bulbus Fritillariae was taken as a principle medicine. The Prescriptions are compounded with Bulbus Fritillariae as a principle medicine can aplly to respiratory disease, eye disease, nose and ear disease, throat disease, a boil. Various pathogenic factors such as consumptive disease, phlegm, phlegm-fire, invasion by wind, affective by cold, fire, dyspepsia-fire are put to practical use. The dosage of Bulbus Fritillariae is 5 bun (about 1.88g) to 1 lyang(about 37.5g), however 1 jeon(about 3.75g) has been taken the most for clinical application. With examination the formulae of presciptions containing Bulbus Fritillariae, I found the basic prescriptions as well as the medicines are in conjunction with Bulbus Fritillariae and the theoretic grounds of formula in combining Bulbus Fritillariae as a group of medicine for presciption through this reseach.

        다중 생체인식 알고리즘을 적용한 개인 인증 시스템

        임대환 한국정보기술학회 2017 한국정보기술학회논문지 Vol.15 No.12

        In this paper, a mobile personal authentication system was developed using multimodal Biometrics signals. The multimodal Biometrics signals used were used with facial, eye, fingerprint, and PIN input. In the biological signal used, the Face Correction algorithm extracted only a specific channel from the raw data to detect faces and Median Filtering was applied to eliminate noise. The Eye Detection algorithm is applied to compare the eye position and eye line of the learned user with the current user. The algorithm used for fingerprint recognition is based on gradient-based fingerprint recognition algorithm. The fingerprint area and features are extracted through this, 16 combination algorithm that can perform real-time authentication processing for the first time in the world has been developed. 본 논문에서는 다중생체신호를 이용한 실시 간 모바일 개인 인증 시스템을 개발하였다. 이용된 다중생체신호는 얼굴과 눈, 지문, 그리고 PIN입력을 사용하였다. 이용된 생체신호의 Face recognition 알고리즘은 Raw Data에서 특정 채널만 추출하여 얼굴을 검출하고 노이즈를 제거하기 위하여 Median filtering을 적용하였고, Eye Detection은 학습된 사용자의 눈의 위치 및 시선을 현재 사용자와 비교하여 인증하는 알고리즘을 적용하였다. 지문은 그래디언트 기반의 인식 알고리즘을 사용하여 특징과 지문 영역 추출하여 인증에 사용하였다. 이를 통하여 세계 최초의 16개 조합의 인증 알고리즘이 구현되어 단일 인증 방법 대비 향상된 보안 인증시스템을 구현하였다.

        황련해독탕(黃連解毒湯)이 Dextran Sulfate Sodium 유도 마우스 대장염에 미치는 영향

        임대환,윤지연,장선일,윤용갑,Lim, Dae-Hwan,Yun, Ji-Yeon,Jang, Seon-Il,Yun, Young-Gab 대한한의학방제학회 2011 大韓韓醫學方劑學會誌 Vol.19 No.2

        Objectives : Hwangyeonhaedok-tang(HHDT) has been traditionally used for various clinical symptoms associated with gastrointestinal disorder, cardiovascular diseases, and inflammation in the Oriental medicine. However, little is known for antioxidant and anti-inflammatory effects of HHDT on dextran-sulfate sodium(DSS)-induced colitis in mice. Methods : In this study, we investigated an antioxidant and anti-inflammatory effects of HHDT on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. HHDT was orally administrated the various concentrations(25-100 mg/kg, body weight/day) for 7 days with one time per day. Results : HHDT reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, disease activity index(DAI), and histological colon injury. HHDT also inhibited significantly serum NO and prostaglandine $E_2(PGE_2)$ productions in DSS-induced colitis mice. Furthermore, HDDT increased significantly an superoxide anion(SOD), catalase, and glutathione peroxidase(GPx) activity of the colon tissue in DSS-induced colitis mice. Conclusions : These results suggest that HHDT administration could reduce significantly the clinical signs and inflammatory mediators, and increase antioxidant activity in DSS-induced colitis model mice and is a good candidate for further evaluation as an effective anti-ulcerative agent.
