Objectives : The Hwabyung Research Center of The Korean Society Of Oriental Neuropsychiatry has attempted to develop the 'Clinical Guidelines for Hwabyung'. Methods : The Hwabyung Research Center constructed a committee of experts and advisory group. Relevant literature was collected and evaluated in order to discover effective oriental psychotherapy as well as the management of Hwabyung. Results : We found some evidences that proved the effectiveness of oriental psychotherapy in the treatment of Hwabyung. The principles of management were also reviewed. Conclusions : Psychotherapy and management for Hwabyung were studies. We hope that the 'Clinical Guidelines for the Treatment of Hwabyung' is helpful for both oriental medical doctors and patients.

Objectives: This study aimed to understand the influence of acupuncture on the human body by comparing changes within human bodies before and after people in normal health are treated with acupuncture at the acupoints HT7 and PC9, which are related to mental functions. Methods: The study was performed from January 3, 2008 to March 5, 2008 on 60 healthy males and females in their 20s. HRV, EEG, skin conductance response, respiration and peripheral skin temperature were measured for 5 minutes before acupuncture simulation was applied to the acupoints HT7 and PC9. During 20 minutes of acupuncture treatment, the same items were continuously measured to determine whether there had been any changes, and they were then measured for 5 minutes after the removal of the acupuncture needles in order to implement a comparative analysis. Results: 1. The HRV measurement showed that in the course of before, during and after acupuncture stimulation, heart rate, HF and HF norm decreased significantly (P<0.05) at HT7. LF, LF norm, and LF/HF ratio increased significantly (P>0.05), while heart rate, HF and HF norm decreased significantly (P<0.05) at PC9. 2. Skin conductance response increased significantly (P<0.05) at PC9 during and after the acupuncture simulation periods, compared with the pre acupuncture period. 3. the peripheral skin temperature increased significantly (P<0.05) both at HT7 and PC9 in the course of before, during and after acupuncture stimulation. 4. Compared with the pre-acupuncture period, respiration rate increased both at HT7 and at PC9 during and after the acupuncture simulation periods, but not in a statistically significance. 5. In the EEG measurement, when compared with the pre-acupuncture period at HT7, mid β wave decreased significantly (P<0.05) during acupuncture treatment. Compared with the measurements during acupuncture treatment at PC9, low β wave increased significantly (P<0.05) after the acupuncture needles were removed. Conclusions: When acupuncture treatment is applied at the acupoints HT7 and PC9, the activation of parasympathetic nerves decreases and the activation of sympathetic nerves increases in the HRV measurement. It was determined that PC9 makes the sympathetic nerves become highly activated in a skin conduction response. The effect of stability in the brain wave seemed to bo shown at HT7 than PC9.

본 논문에서는 극 좌표계에서의 벡터 표현 방식을 이용한 per-pixel displacement mapping 방법을 제시한다. Per-pixel displacement mapping 은 triangle mesh 의 처리 방식에 상관없이 변위매핑을 수행할 수 있도록 한 것으로, 2 차원 screen space 로 projection 된 triangle 의 각 pixel 의 위치를 객체 표면 정보에 따라 displacement 해주는 방법이다. 이는 기 검증된 범프매핑 하드웨어에 약간의 하드웨어를 추가함으로써 변위매핑을 수행할 수 있도록 한 효과적인 구조이다. 제안 방식에 의해 생성된 영상과 기존 방식에 의해 생성된 영상을 비교해본 결과, 시각적으로 거의 차이가 없음을 알 수 있다.

There has been research about visual recognition for video surveillance and various algorithms are advancing. This paper proposes a optimized system designed to improve rate of visual recognition using SUHF(Speed Up Robust Feature) algorithm that has been widely used with a scale and rotation invariant feature descriptor. We have also implemented visual recognition system using constraints of properties of homography matrix and RANSAC(Random Sample Consensus) for removing mismatched feature points.

한방정신요법과 서구 정신요법의 비교연구

이승기 ( Seung Gi Lee ) 대한한방신경정신과학회 2010 동의신경정신과학회지 Vol.21 No.1

Objectives: Oriental psychotherapy and western psychotherapy in Korea were investigated in order to develop a new oriental psychotherapeutic model for modern Korean. Methods: Oriental psychotherapy and Western psychotherapy were compared and investigated in some viewpoints such as cognition, behaviour, emotion and ultimate purposes for the therapies. Cultural differences are examined, too. Results: There are clear differences between two psychotherapies. It seems that cognition is more important than behaviour or emotion in western psychotherapy. On the other hand, emotion is more important than cognition or behaviour in oriental psychotherapy. Ultimate purposes for the therapies are also different because of cultural differences. Conclusions: New oriental psychotherapeutic model considering cultural differences and merits of two therapies is needed.

기업 간 장기적 관계지향성이 그린공급사슬관리와 성과에 미치는 영향

이승기 ( Seung Gi Lee ),김병근 ( Byung-keun Kim ),박영찬 ( Young Chan Park ) 한국중소기업학회 2017 中小企業硏究 Vol.39 No.1

최근 환경에 대한 인식이 높아지면서 그린공급사슬관리(GSCM)에 관한 관심이 증가되고 있다. GSCM에 관한 실무적 관심이 증가함에 따라 학계에서도 환경경영에 관한 학술적 연구들이 다양한 관점에서 제시되고 있다. 그런데 대부분의 연구는 주로 대기업인 모기업 중심으로 1차 협력기업과의 관계를 연구대상으로 제시하고 있다. 1차 협력사는 공급사슬채널의 중간에 위치하고 있어 환경경영에 결정적인 역할을 담당하고 있다. 본 연구는 1차 협력사를 중심으로 기업의 기업 간 장기적 관계 지향성이 그린공급사슬관리와 성과에 미치는 영향을 분석하였다. 대·중소기업 그린파트너십과 대·중소기업 탄소파트너십 프로그램에 참여하고 있는 1차 협력기업을 대상으로 수집한 설문 조사결과를 구조방정식을 활용하여 연구모형과 가설을 검증하였다. 분석결과 첫째, 기업 간 장기적 관계지향성이 GSCM 실행 요소인 환경정보협력, 그린구매 그리고 그린제품설계를 촉진하는 요인으로 밝혀졌다. 또한 GSCM의 하위변수 간의 상호 관련성을 추가적으로 분석한 결과 환경정보 협력이 그린구매와 그린제품설계에 영향을 주는 것으로 확인되었다. 둘째, GSCM 실행 요소인 그린구매, 그린제품설계는 환경성과에 긍정적으로 영향을 미치나 환경정보협력은 환경성과에 직접적인 영향을 미치지 못하는 것으로 밝혀졌다. There is growing concern of the international community for the environmental issues including climate change. Scholars have examined various issues regrading Green Supply Chain Management (GSCM) but they mainly have focused on why firms introduce and implement GSCM from the persecutive of manufacturers. In particular, there has been few studies of green supply chain management in Korea. We investigate the effects of long-term relationships on green supply chain management and the relationship between GSCM and environmental performance. We also examine the relationship between long-term relationships and green information sharing, the effects of green information sharing on the GSCM. The data for this study were collected through a questionnaire survey on firms that participated in the Green Partnership Program of Korea Institute of Industrial Technology. Based on the responses of 155 firms the research model is empirically tested through a structural equation model. We found that long-term relationships facilitate GSCM significantly as it was expected. Green purchase and green product design also appears to improve environmental performance. Long-term relationship appears to affect positively green information sharing. Green information sharing does not have a statistically significant effect on environmental performance but show positive effect on GSCM including green purchase and green product design.
