Objectives: The objective of this study is to examine the effects of Emotion Freedom Techniques (EFT) group treatment program for Hwa-byung patients. Methods: Thirteen Hwa-byung patients have participated in the four weeks program of EFT group treatment and the program was executed once a week, for about one hour. After every session, the participants performed EFT by themselves in order to control their symptoms. Four weeks after the program ended, we interviewed the participants by using the semi-structured interview method to observe changes of Hwa-byung. All the data collected was summarized through the qualitative analysis method. Results: Results showed effects of the EFT group treatment program, with regards to the physical, cognitive and emotional aspects. Most of the participants experienced reliefs of Hwa-byung symptoms like chest tightness, hot flashes, insomnia and so on. Their ability to cope with stress improved and their re-experiences of past memories decreased. And their distorted self-images were also restored. Lastly, there was a decrease in negative emotions and an increase in positive emotions experienced by the participants. The participants could control their symptoms by performing self-enforcement. In addition, regarding the form of group therapy, the treatment was effective as it helped the participants to feel solidarity and social support. Conclusions: The EFT group treatment program can relieve the physical, cognitive and emotional symptoms of Hwa-byung. This program can be applied to the psychotherapy of Hwa-byung.

Objectives : This study has the object to evaluate the effect of meditation at the clinical field and to classify the profer meditation by the emotional states of patients. Methods : Thirty volunteers have been recruited using local advertisement. They devided into two groups(patient group, normal group). Emotional states and stressors (STAI, STAXI, BDI, SCL-90-R, Stress Response inventory, Life event stress) have been evaluated. After that test HRV(Heart Rate Variability) has been tested and subjects took a 5-minute rest. After that, one of meditation has been chosed and has been demonstrated for 10 minutes by practiced trainer(Autogenic Training, Fruit Imaginary Meditation, Random assignment). After 5 minutes resting time, HRV has been measured again with meditation that had been administered. Results : 1. The higher the scale of emotional index, the more sensitively react has been occured according to the meditation. 2. The rate of HRV index that means stable state is higher in Fruit Imaginary Meditation group who thought to be administered meditation well. 3. The Fruit Imaginary Meditation is more effective immediately than Autogenic Training assessed by HRV scale and VAS scale of well-administered meditation especially in patients group. 4. Subjects of Highly suffered emotional problem have more effect in Fruit Imaginary Meditation Group compared to Autogenic Training Group. Conclusions : Suitable beginner meditation course considered patient's emotional problem needs to be programmed.

Objectives : To investigate contributing degree of other factors except pelvic tilting to F.L.L.D by analizing with Gonstead technique on the correlation between femur head height discrepancy on the standing pelvic AP view and F.L.L.D caused by pelvic tilting. Method : We analysed standing pelvis AP X-ray of 70 patients who had visited at the department acupunture and moxibustion in Conmaul oriental medical hospital, during May, 1st, 2004 - July, 30th, 2004, with low back pain or lower extremity pain. We excluded the person with any past history of polio, genetic defect, malunited fracture, growth plate injury, infection and overgrowth attributable to hemangioma, or arteriovenous fistula. Results & Conclusion : The functional leg length discrepancy caused by pelvic tilting and femur head height difference had no statistical difference(p=0.132) but poorly correlated(Pearson ${\nu}=0.05$). In the 94.28% of subjects, the femur head height difference wasn't in accord with F.L.L.D. caused by pelvic tilting. In 47.14% of subjects were expected to have over $3^{mm}$ of leg length discrepancy after pelvic adjustment. The mean of measurement difference between two methods was $3.76{\pm}3.12^{mm}$ and the range was $0{\sim}11.4^{mm}$. Consequently, we must consider not only functional leg length discrepancy caused by pelvic tilting but also anatomical leg length discrepancy, misalignment of ankle, knee or hip joint etc.

Objective: There are many meditation methods used in clinical field. But the effect of meditation may be different to people's mind, and meditation itself. Now we investigate this subject with two different meditation methods which has been analyzed by heart rate variability. Method: We tried to check people's heart rate who educated meditation, before educated and during the meditation. The meditation was educated differently for each group. One is the auto genes traning, and the other is the imaginary meditation by thinking about eating and smelling favorite fruits. All of them are used to oriental psychiatry clinic patients. And we simultaneously conduct people's emotional state by SCL-90-R. Result: The result in Autogene traning group has significant difference in total power and HRV-index score between before and during the training but in imaginary meditation group has no significance: Autogene traning group has a significance in low frequency score and has increased tendency with increasing tendency of Heart rate index and Total power. Through the SCL-90-R score, the higher depression t-score, the anxiety t-score, and the hostility score is, the HRV scores such as total power, low frequency, and HRV-index much increase. and so on. Conclusion: We can guess that the Autogenes training has more significant effect than the imaginary meditation. And we can also guess that as the emotional problem is getting more severe, the effect of meditation would be much better. And we finally suggest that we should make a standard guideline of imaginary meditation, cause the imaginary meditation has so many variation.

To schedule a Reconfigurable Manufacturing Cell (RMC), reconfiguration and setting decisions should be made first. Those decisions, together with characteristics of production orders, affect attainable performance of a system. So an integrative approach is required considering all decisions and characteristics rather than dealing with each of them separately. Pallet-fixture allocation, as a decision problem in setting, which determines the number of pallets to be equipped with each fixture type to produce different types of products, has rarely been investigated. In this study, several pallet-fixture allocation rules are proposed including both simple and novel ones. Then system performance is investigated through various combinations of setting and scheduling decisions (rules) for given system configurations and production orders, via simulation. The result shows that one of proposed pallet-fixture allocation rules which considers both configuration and order characteristic outperforms the others, justifying the necessity of an integrative approach in the RMC operation.

본 논문에서는 부분적인 지면효과 하에서의 단일로터 블레이드에 대한 제자리 비행 성능 특성을 확인하였다. 이를 위해 소형 로터 블레이드 회전 시험장치와 이동식 바닥면을 이용하여 고정된 회전속도에서 콜렉티브 피치각을 변화시키면서 추력과 토크를 측정하였다. 로터면과 지면이 겹치는 거리를 d, 로터의 직경을 D라 하면 지면효과가 없을 때부터 d/D가 0.25일 때까지는 지면효과가 로터의 성능에 거의 영향을 미치지 않는 것으로 확인되었다. 로터 깃의 개수가 4개일 때 지면 효과의 영향을 더 크게 받아 2개일 때보다 추력이 증가하고 동력이 감소하였다. 또한 피치각이 작을수록 지면효과로 인하여 추력이 증가하는 경향을 보였다. 이와 같은 실험 결과를 바탕으로 로터 깃의 개수와 부분적인 지면 효과를 고려한 새로운 경험식을 도출하였다.

본 논문에서는 시간전진 자유후류 모델이 고려된 비정상 패널 코드를 이용하여 비정상 로터-동체 상호작용에 대한 수치적 해석기법에 대한 연구를 수행하였다. 이전 개발된 시간전진 자유후류 모델이 고려된 비정상 패널 코드는 후류와 깃(Blade)이 아주 근접한 경우에 불안정성이 발생하였다. 이를 제거하기 위해 장속도 기법을 적용하여 코드를 개선하였다. 개선된 코드를 이용하여 NASA에서 실험된 ROBIN(ROtor Body Interaction) 형상에 대한 해석을 수행하였다. 로터가 있을 때와 없을 때의 동체 표면 압력과 유도 유입류의 비를 실험결과 및 기존 수치해석 결과들과 비교하였다. 개발된 코드는 로터-동체 상호 작용으로 인해 발생하는 유동 특성과 생성되는 복잡한 후류의 형상을 잘 예측하였다.

Objectives : This study was to evaluate the clinical effectiveness of Bee Venom acupuncture therapy for acute ankle sprain. Methods : From September 1st, 2005 to December 31st, 2005, the 60 patients who had visited Conmaul oriental medical hospital with acute ankle sprain were sample into 2 groups for this study; one group for the bee-venom acupuncture therapy combined with needle acupuncture therapy and the other group for needle acupuncture therapy only at least 3 times respectively. Both group had been treated with same additional infrared lamp, physical therapy and ankle supporter during the whole treatment period. Among 60 patients, 20 participants satisfied the whole inclusion criteria. To estimate the efficacy of treatments, Numerical Rating System(NRS) and Ankle-Hindfoot Scale(AHS) were applied before 1st and 4th treatment. Each score results were analysed and compared by Mann-Whitney test and Wilcoxon signed rank test with the level of 5% significance. Result : The NRS score in bee-venom acupuncture therapy group was increased significantly and the AHS score in bee-venom therapy group was decreased significantly compared to each of single acupuncture therapy group(P<0.01). The score change comparisons between the two groups had no significance before and after the treatment. Conclusion : Both bee-venom acupuncture therapy and single acupuncture therapy were effective to treat the acute ankle sprain. but there were no significant data to prove that bee-venom acupuncture therapy is more effective than single acupuncture therapy.

Cu(In,Ga)Se2 (CIGS) 화합물 반도체를 기반으로 한 태양전지는 박막태양전지 기술 중 세계최고효율을 기록하고 있다. CIGS를 합성하는 방법은 동시증발법, 스퍼터링/셀렌화 등의 진공방식과 나노분말법, 전착법, 용액법 등의 비진공방식이 있으나, 현재까지 진공방식이 양산기술로서 완성도가 높은 것으로 알려져 있다. 특히 스퍼터링에 의한 전구체 박막 증착과 셀렌 분위기에서의 열처리 공정을 결합시킨 2단계 공정은 동시증발법에 비해 대면적 모듈 제조에 유리한 것으로 알려져 있다. 셀렌화 공정은 통상 반응성이 매우 높은 H2Se 기체를 이용하고 있으나, 부식성 및 안전성 문제를 해결하기 위해 추가적인 설비가 요구되므로 제조비용을 높이는 단점을 갖는다. 한편, Se 증기를 이용하면 안전성은 담보되나 낮은 반응성으로 인해 고온에서 장시간 열처리를 해야하는 문제를 안고 있다. 본 연구에서는 새로운 Se 증기를 사용하되 반응효율을 높일 수 있는 새로운 셀렌화 열처리방법을 제시하고자 한다. 기존의 Se 증기가 별도의 증발원을 이용하여 공급된 것과는 달리, 금속전구체 직상부에 Se이 코팅된 별도의 커버글라스를 위치시켜 Se의 손실을 최대한 억제하였다. Se 커버글라스가 밀착된 금속프리커서를 $200{\sim}600^{\circ}C$ 온도범위에서 열저항가열로 내부에서 열처리하였으며, 추가로 Se을 공급하지는 않았다. 이와 같은 방법 제조된 CIGS 박막의 물성을 X선회절법, 주사전자현미경 등으로 관찰하였으며, 예비실험결과 비교적 낮은 온도에서 chalcopyrite 상이 형성됨을 확인하였다. 근접셀렌화에 의해 제조된 CIGS 박막이 적용된 태양전지를 제조하여 셀렌화 공정변수에 따른 소자특성변화를 제시하고자 한다.
