일상적인 상황에서 방위산업에 관련된 물류관리의 중요성은 일반 산업에 비하여 크지 않으나, 예외적인 상황이 발생했을 때에는 신속한 해결책을 찾아내어 문제를 해결하지 않으면 국방에 있어서 전략적 공백으로 이어질 수 있다. 그러므로 예외상황에 대한 신속한 대비책을 구축하는 것이 필요하며 본 논문에서는 업무절차관리(BPMS) 시스템을 도입하여 물류 프로세스의 지속적인 개혁 및 개선을 유도한다. 이를 위하여 프로세스 저장소의 사용을 제안하며, 예외발생시 신속한 처리방안을 검색하기 위한 검색트리의 사용방법론을 제시한다. 획일적인 업무처리가 강조되는 군사작전 및 방위산업의 환경 하에서 예외상황의 처리를 위한 효율적 장치를 마련하는 것은 방산운용의 측면에서 매우 중요하다. 본 논문에서는 특히 지식경영의 관점에서 예외처리 시 생성되는 새로운 프로세스 지식을 프로세스 저장소(process repository)에 저장하고, 예외발생시 이 문제의 해결에 적합한 프로세스를 저장소에서 신속하게 검색하는 데 활용할 수 있는 검색트리의 생성과 활용에 대한 방법론을 연구하였다. 검색트리의 생성과 활용을 위하여 ‘상황변수’와 ‘의사결정변수’의 개념을 새로 도입함으로써 문제의 상황을 체계적으로 기술하고 저장 및 검색하는 방편을 제시하였으며, 예외상황의 인식능력(context awareness)을 제고시켰다. 정보의 엔트로피를 기초로 한 C5.0 알고리즘을 적용하여 정보이득을 최대화하는 검색트리를 생성하는 방법을 제시하였다.

A Study on Storage of Major Herbal Medicine Materials, Zingiberis Rhizoma

Choi,Seong-Kyu,Yun,Kyeong-Won,Shin,Kil-Man 한국자원식물학회 2002 Plant Resources Vol.5 No.3

To develop optimal storage method of root of Zingiberis Rhizoma, which has been grown as major cultural herbal medicine materials, root of Zingiberis Rhizoma, was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. Conclusionally, vacuum packing and complete sealing with polyethylene film appears to be optimal for storage of Zingiberis Rhizoma.

본 고에서는 재무변수와 경제변수에 의한 한국과 영국, 미국의 전체 주식시장 수익률 예측력을 조사하고 이들 국가들의 자본시장 동조화 현상에 대하여 연구하였다. 단기 금리는 전체 주식시장 수익률을 예측하는 데 중요한 역할을 한다. 배당수익률은 미국과 영국의 주식시장 수익률과 어느 정도 예측력을 가진다. 이익수익률은 세 시장 모두에서 거의 설명력이 없다. 그렇지만 단기 금리만으로는 세 국가 모두에서 주식 수익률을 예측하기 어렵다. 단기 금리와 배당수익률을 동시에 고려할 때 예측력이 가장 높아진다. 그러나 이들 회귀식의 설명력들은 설명력이 매우 낮아서 효율적 시장가설을 기각하는 증거로 받아들이기 어렵다. 한편 미국 관련 변수들은 한국과 영국의 주식수익률예측에 도움이 된다. 영국 관련 변수 역시 미국 시장수익률 예측에 도움이 된다. 이들 시장은 단기적으로 통합되어있지 않으며 특히 한국 시장은 영국과 미국시장과 단기적으로 독립적이다. 그렇지만 전반적으로 이들 3개국 사이에는 오차수정에 의한 장기 균형 관계가 존재하며 기대수익률에 공통된 움직임이 있다는 증거가 있어서 장기적으로 동조화되어 있음을 알 수 있다. 이러한 관계는 표본기간의 후반기인 2000년대에 더욱 두드러지게 나타나서 시장의 균형을 향상 조정속도가 빨라지고 있다

This study was conducted to investigate wintering ecology and habitat using pattern of cranes for sound protection and management of the birds and their habitat near the Demilitarized Zone(DMZ) of Cheolwon, South Korea. Distribution of cranes seemed to be affected by road construction and human activity. Dried rice paddy was mainly habitat type of cranes in Cheolwon area. Gleaning was dominant behavior during day time. Ratio of alert was increased in afternoon. There was difference in time budget of behavior between red-crowned and white-naped cranes. For the stable wintering of cranes, minimum change of habitat, decrease of human disturbance and stable food maintenance would be needed in Cheolwon area.

<B>Graphic Abstract</B> <P>The cover shows a schematic illustration of patterned colloidal photonic crystals with different bandgap positions. When an unknown light source impinges on the patterned photonic crystals, the light information can be identified from the reflection intensity profile of the constituent photonic crystals. The two optical microscopy images and background image display integrated photonic crystals with 20 different bandgaps spanning the entire visible range, and the SEM image shows the cross-section of the photonic crystal stripes, as reported by Shin-Hyun Kim, Seung-Man Yang, and co-workers on p. 946. <img src='wiley_img_2010/09359648-2010-22-9-ADMA201090022-content.gif' alt='wiley_img_2010/09359648-2010-22-9-ADMA201090022-content'> </P>

A low-Reynolds-number second moment turbulence closure is improved with the aid of DNS data. For the model coefficients of pressure-strain terms, we adopted Shima's model with some modification. Shin and Choi's new dissipation-rate equation is employed to simulate accurately the turbulence energy dissipation rate distribution in the near wall sublayer. The results of computations are compared with DNS, LES data and experimental data for turbulent plane channel flow with rotation about spanwise axis. The present second moment closure achieves a level of agreement similar to that for the non-rotating. In particular, it accurately captures the distribution of turbulence energy dissipation rate in the near wall region.

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

Reactive Perforating Collagenosis (RPC) is a kind of perforating dermatosis, which shows transepidermal elimination of altered collagens. Acquired form is developed in an adult without family history, is favorably developed in scratched region due to pruritic sense. Acquired RPC has been reported to be associated with various systemic disorders, such as diabetes mellitus, liver disease, chronic renal failure, lymphoma, AIDS, hypothyroidism, hyperparathyroidism, and neurodermatitis, accompanied by itching & scratching. We report a case of acquired RPC in a patient with HCV hepatitis who was treated with interferon alpha. Skin lesions showed multiple erythematous centrally umbilicated, crusted papules of variable sizes on the extensor surfaces of both shins. (Korean J Dermatol 2008;46(6):788∼791)

Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.
