The purpose of this research is to suggest the policy making for the effective promotion of Quality Small-Group activity. Since 1975, variety of organizations in Korea have widely the implemented Quality Small-Group activities for their management systems. Today, Companies are facing the harsh realities of a competitive environment. This is no time for revolutionary change. Instead, Companies are instituting revolutionary change meant to have impact within a very short time frame. Bold steps are required to lead the industry into a future of improved efficiency and significant productivity gains. The Worker's Quality Small-Group activity is, essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. The industries have enthusiastically used Quality Small-Group activities and were influenced from them. The Quality Small-Group activities can be regarded as a kind of Knowledge Management where new knowledge is created and knowledge is shared in the economy. However, the academics were less interested in this subject, as a result, there were no systematic guidances for Quality Circle activities. Also, the government was less interested in these activities, as a result, there were no systematic policy making for Quality Small-Group activities. Thus, in this research, the effective policy making for Quality Small-Group activities were suggested which were based on the results of survey Questionnaires. As a results of this research, to maximize the effect of TQM in the nationwide, Quality Small-Group activity as a bottom-up management should be more expanded and revitalized.

經絡과 經穴의 客觀化를 위한 經絡現象의 理解

具成泰,孫仁喆 圓光大學校 韓醫學硏究所 1997 원광한의학 Vol.7 No.1

최근에 많은 연구자들이 經絡과 經穴의 客觀化를 위해서 많은 노력을 기울이고 있다. 이번 論文에서는 이러한 문제에 관해서 연구된 결과를 이용하여 經絡現象에 대해서 살펴본 결과 다음과 같은 結論을 얻게 되었다. 1. 經絡과 經穴은 形態學的으로 자체적인 독특한 構造는 아직까지 발견된 것이 없으며, 神經系와 內分泌系가 관련되어 있다. 2. 經絡은 에너지를 制御·統制하는 정보계로서 정보 에너지의 교환 통로가 된다. 3. 鍼治療의 疼痛에 대한 鍼痛作用의 機轉은 神經終末, 脊椎, 腦幹, 視床下部, 腦下垂體 등이 관련되어 있다. 4. 鍼治療의 疼痛에 대한 鍼痛作用의 機轉은 求心性 經絡(afferent pathway)와 遠心性 經絡(efferent pathway descending pain inhibitory system)로 나누어 볼 수 있다. 5. 한의학 이론의 氣至感應과 PSM(propagated sensation along the meridians)은 밀접한 관계가 있으며 鍼의 治療效果에 대한 客觀的인 根據가 된다. 6. 經穴은 칼슘이온 농도가 높아서 전류가 잘 통하며, 그리하여 電氣抵抗이 낮은점이 된다. In recent years, not a few researchers have paid much attention to objectification of the meridian and acupuncture point. In the present paper, by using the result of the investigation on this problem, have made a survey on the understanding of Merdian Phenomena Conclusion was as follows. 1. Characteristic structure of the meridians and acupuncture points have not yet been found in morphology, but it has been reported that it is connected with nervous system and endocrine system. 2. The meridian is transporting channel of information and energy as a energy control system. 3. Mechanism of acupuncture analgesia in acupuncture therapy is related with nerve ending, spinal cord, brain stem, hypothalamus, pituitary gland etc. 4. Mechanism of acupuncture analgesia divides into two paths. One of these is the afferent pathway and the other is the efferent pathway(descending pain inhibitory system). 5. 'QiGiGamYuˇng'(氣至感應; special sensorized feeling of the Qi after acupuncturing or manipulation) and PSM (propagated sensation along the meridians) are deeply associated with each other, and are the objective evidence of acupuncture therapeutic effects. 6. Acupuncture points are the site in which electric stream is well conducted for the high density of calcium ion, therefore they are low electric resistance points.

CALPUFF model과 ISCST3 model을 이용한 악취모델링 기법 연구

구윤서,김성태,김용규,송선호 안양대학교 산업기술연구소 2002 自然科學硏究 Vol.9 No.-

악취는 인간의 후각기관에 의해 감지되기 때문에, 대상 지역의 평균농도(Average Concentration) 보다는 악취의 특성상 순간적인 농도인 첨두농도(Peak Concentration)가 중요한 의미를 갖는다. 따라서 이것을 모델링에 적용하기에는 많은 어려움이 있다. 이를 해결하는 것이 이 연구의 주된 과제라 할 수 있다. 현재 국내에서 환경영향평가에 많이 사용되고 있는 ISCST3 Model (Industrial Source Complex Short Term 3 Model)과 CALPUFF Model (California Puff Model)을 사용하여 첨두농도(Peak Concentration)를 고려한 관능악취도(Odor Intensity)를 두 가지 방법으로 산정 하였다. 첫 번째로는 오염원에서 배출되는 물질의 농도를 이용하는 방법과 다른 하나는 종합악취도 개념으로 악취농도(Odor Concentration)를 이용하여 관능악취도를 산정하는 것이다. 위의 두 가지 방법을 ISCST3 Model과 CALPUFF Model에 적용하여 모델링을 수행한 후 나온 기여농도를 첨두농도로 환산한 후 관능악취도를 계산하였다. 이와 같은 이론 배경을 바탕으로 현장 적용성을 파악하기 위해서 수도권매립장의 한 지점에서 가상의 가스배제공이 있다고 가정하고, ISCST3 Model과 CALPUFF Model에 동일한 조건으로 모델링을 수행하여 매립장 주변에 미치는 관능악취도를 각각 산출해 비교 검토하였다. 그 결과 두 모델에서의 차이는 크지 않았으나 기여농도와 첨두농도 사이에는 상당한 차이를 보였다. 결과적으로 악취모델링을 수행함에 있어서 기여농도만을 고려하는 것은 관능악취도를 과소평가 할 우려가 있으므로 배출원 특성을 고려한 첨두농도로 관능악취도를 평가하는 것이 타당하다고 판단된다. In order to manage the odor related public complains effectively, the estimation of peak ground-level concentration which is capable of predicting the intermittent maximum response less than 10 seconds is very important. However, peak rather than 3 minute or 1 hour average concentrations are not easily predicted by current air dispersion models such as SCST3 (Industrial Source Complex Short Term - version 3) and CALPUFF (CALifornia Puff) models. According to the field and wind tunnel measurements, the intensity of the peak concentration depends on the emission source type, downwind distance and atmospheric stability. The odor modeling methods to predict the peak concentration were reviewed and the detailed procedure for the odor modeling was explained in this study. In order to compare the conventional air dispersion models with the oder models, the odor concentrations with various modeling techniques under the identical emission and meterological conditions were calculated. The peak concentration shows highest value than the 3 minutes or 1 hour average concentrations. The predicted odor concentrations by the CALPUFF model are higher than those predicted by the ISCST3 model since the CALPUFF model reflects the time-dependent movement of the plume. It is recommended that using the peak concentration with the CALPUFF model rather than 3 minutes or 1 hour average concentrations is more reasonable approaches to manage the odor problems.

구성태,신종근,최윤영,송정방,김재효,김경식,손인철 한국전통의학연구소 2006 한국전통의학지 Vol.15 No.1

Objectives: This study was produced to examine the effects of moxibustion that had been played important role to traditional oriental medical treatment on disease. Recently, it was reported that moxi-tar which is generated in the process of moxibustion as burning combustibles decreased nitric oxide(NO) and inducible NO synthase (iNOS) generation in cellular experiments. Methods: Carrageenan-induced arthritis rat model was used to test the effect of moxi-tar as a chronic pain model. Diluted moxi-tar was single injected in several acupoints or combined with electroacupuncture (1 ms, 2 Hz, and 2 mA) into contralateral ST36 acupoint for 30 min to assess the synergic effects. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 12 hours. Endogenous NO and iNOS, cyclooxygenase-2 (COX-2), and c-Fos protein expression in the spinal cord were examined on a rat model of carrageenan-induced arthritis. Results : After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 4 days. The reduced stepping force of the limb was presumably due to a painful knee, since oral injection of indomethacin produced temporary improvement of weight bearing. Moxi-tar produced significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 9 hours. The magnitude of this improvement was equivalent to that obtained after an oral injection of 3 mg/kg of indomethacin and this improvement of stepping force was interpreted as an analgesic effect. Moxi-tar produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner. Both NO production and iNOS, COX-2 protein expression increased by arthritis were suppressed by moxi-tar. Moxi-tar on combination with electroacupuncture (EA) produced more powerful and longer lasting improvement of stepping force of the hindlimb affected by the arthritis than either moxi-tar or EA did. Conclusion : The present study suggest that moxi-tar produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and that moxi-tar-induced analgesia modulate endogenous NO through the suppression of iNOS/COX-2 protein expression.

구일섭,김태성 남서울대학교 2005 남서울대학교 논문집 Vol.11 No.2

The purpose of this study is to propose the effective guidance of Quality Small Group(or Quality Control Circles) activities. The Quality Small Group activities started in Japan during the 1960s. In the study, we have paid much attention to propose the guidances of the problems found during the initial stages and the appreciation of the achievements of Quality Small Group activities until now. We surveyed the previous proceedings of the company-wide, local and domestic contests of Quality Small Group activities, present some of them as evidences of our arguments, and try to establish principles of activation of that. We also suggest principles residing in the activities and propose the desirable direction of Quality Small Group movement in Korea. From the results of our analysis, we recognized that there are gaps between some subjective appraisers and team members. These should then be elaborated and grounded in the detailed and accessible directions.

정태기,김현대,류재춘,최석구,유원상 인제대학교 1993 仁濟醫學 Vol.14 No.4

Prostaglandin 합성을 촉진하는 새로운 강압약인 cicletanine의 강압효과를 진료실 혈압과 24시간 활동혈압으로 평가했을 때 상당한 차이를 보여 그 이유를 검토해 보았다. To evaluate antihypertensive effect of cicletanine with both clinic and ambulatory blood pressure monitoring, 10 male hypertensive patients were administered cicletanine, a new antihypertensive stimulating prostaglandin synthesis, in 100∼200 mg daily for 12 weeks. The following were the results. 1.Mean of clinic BP decreased from 161/98 mmHg to 153/98 mmHg. 2.Mean of ambulatory BP changed from 140/91 mmHg to 153/99 mmHg. 3.Side reactions were mild, namely indigestion and constipation. 4.Discrepancy between clinic and ambulatory BP were discussed. In conclusion cicletanine revealed slight antihypertensive effect with clinic blood pressure, but failed to confirm it with ambulatory blood pressure.

최석구,김현대,정태기,김대현,김용복,유원상 인제대학교 1994 仁濟醫學 Vol.15 No.2

만성 심부전 환자에게 새로운 경구용 비 digitalis 강심제인 denopamine 1T(5mg)을 1일 3회 3개월간 투여하여 그 유효성 및 안전성을 검토했다. Background : Patients with congestive heart failure have a high mortality rate and are also hospitalized frequently. We studied the effects of a new oral inotrophic agent, denopamine in patients with chronic heart failure. Methods : 16 patients receiving conventional treatments for heart failure were treat ed with denopamine 5mg tad for at shortest 3 months. Their history were taken and the physical examination, general laboratory test and the echocardiographic examination were done before and after treatment. Results: There were 3 deaths and 1 withdrawal because of worsening heart failure. 5 patients (42%) among 12 patients showed the improvement in their subjective symptoms. The fractional shortening and ejection fraction of the left ventricle were increased by 3.2% and 5.6% respectively in their absolute values. Conclusion : The addition of denopamine to conventional therapy considerably improved the subjective symptoms and the left ventricular function in the limited number of patients with chronic heart failure.
