For a complex scheduling system like time table construction, its optimal solution, if exists, is hard to obtain. In this paper, the scheduling environment is reasonably confined as where objects have their own events competing for better slots on boards, and objects have their own board slot preferences and belong to one or more classes of the society which globally constrains them. Here, two phase method is suggested, where the first phase is human-like preference dirven and the second phase is for fine tuning by considering all the factors given. Designed and implemented in our system HI-SCHED are dynamic object switching, temporal-constraint-driven intelligent backtracking, case-based revisions, object-based approach, and so on. Some satisfaction degrees are also defined to measure the usefulness of our method. In addition, look-ahead dynamic object switching is considered, and additional global constraints are introduced and processed. A simple scheme is also used to verify the usefulness of the post processing scheme.

151종 생약제 추출물이 B형 간염 바이러스 표면 항원(HBsAg)과 항체(HBsAb)의 결합반응 그리고 HBV DNA polymerase 활성에 미치는 효과 : 한국산 각종 생약제를 이용한 B형 간염치료제의 개발

세계인구 43억명 중 B형 간염 바이러스 보균자는 2억 1천 5백만명이며 이중 78%인 1억 6천만명 이상이 아시아 대륙에 집중되어 있다. 한국도 B형 바이러스 간염의 침윤지대이다. 본 연구는 B형 바이러스 보균자 혹은 만성간염을 치료할 수 있는 생약제를 탐색할 목적의 일환으로 한국에서 시판하는 생약제 151종을 구입하여 증류수로 추출하고 여과한 후 냉동건조하여 HBs 항원에 대한 결합능, HBV DNA polymerase억제능, tumor necrosis factor(TNF) 유리에 미치는 영향, 그리고 galactosamine 유발 간염에 대한간장보호 작용을 조사하였다. 151종의 생약제중 0.16㎍/㎖ 농도에서 간염 vaccine 내에 함유된 HBs 항원과 결합하는 생약제는 지유, 가자, 복분자, 대황, 정향, 빈량, 산수유, 소목, 마황, 쇄양, 후박, 목과, 양강, 오약, 산사, 목단피 등 16종이었다. 이들 생약제중 대황(Rheum palmatum L. 大黃), 가자(Terminalia chebula R. 訶子), 지유(Sanguisorba officinalis L. 地楡), 복분자(Rubus coreanus M. 覆盆子)는 HBV DNA polymerase 활성도를 비교적 강하게 억제하였으며 빈량(Areca catechu L. 빈랑), 정향(Eugenia caryophyllata T. 丁香), 목과(Chaenomeles japonica L. 木瓜), 산수유(Cornus officinalis S. 山茱萸)는 약하게나마 HBV DNA polymerase 활성을 억제하였다. 또한 HBV DNA polymerase를 억제한 대황, 가자, 지유, 복분자, 빈량, 정향, 마황, 소목, 산수유를 대상으로 TNF 유리에 미치는 영향을 조사한 결과 소목을 제외한 8종의 생약제 모두가 대식세포를 자극하여 TNF를 유리시켰다. 그리고 장차 임상에 사용함을 전제로 HBV DNA polymerase를 억제한 대황, 가자, 지유, 복분자, 빈량, 정향, 마황, 소목, 산수유를 galactosamine 유발 간염(백서)에 투여하여 간기능 검사에 미치는 효과를 조사하였으나 간기능 검사상으로는 특별한 보호작용을 나타내지 못하였으며 생약제 단독 투여로서는 간기능에 대하여 나쁜 영향을 주지 않았다. Hepatitis B virus infection is major cause of acute and chrome hepatitis, cirrhosis of liver, and hepatocellular carcinoma. There are over 200 million carriers of hepatitis B virus in the world, nearly 80 % of whom live in the South East Asia, Korea is also highly endemic area of hepatitis B virus infection. This study was performed to evaluate the effect of extracts of traditional Korean herbal medicines on hepatitis B virus. 151 traditional herbs were extracted, filtered and lyophilized. Using 151 herbal extracts we tested binding capability to the HBs Ag, inhibition of HBV DNA polymerase, release of tumor necrosis factor (TNF), and protection against galactosamine induced liver damage. Among 151 herbs, 16 herbs (Sanguisorba officinalis L., Terminalia chebula R., rubus coreanus M., Rheum palmatum L., Eugenia caryophyllata T., Areca catechu L., Cornus officinalis S., Caesalpinia sappan L, Ephedra sinica S., Cynomorium songaricum R., Machilus thunbergii S., Chaenomeles japonica L., Alpinia officinarum H., Lindera strychnifolia V., Crataegus pinnatifida B., Paeonia suffruticasa A. ) had binding capability to HBs Ag which contained in the commercial hepatitis vaccine, at 16 ug/㎖ of concentratioa Among the above 16 herbs, Rheum palmatum L., Terminalia chebula R., Sanguisorba officinalis L., Rubus coreanus M. significantly inhibited the HBV DNA polymerase activity, and Areca catechu L., Eugenia caryophyllata T., Ephedra sinica S., Caesalpinia sappan L., Chaenomeles Japonica L., Cornus officinalis S. also inibited the HBV DNA polymerase activity but less effective. All of the herbs, except Caesalpinia sappan L., which inhibited the HBV DNA polymerase activity, actively stimulated the mononuclear cells to release tumor necrosis factor(TNF) in whole blood culture system. The herbs which inhibited the HBV DNA polymerase activity, did not show any protective effect in galactosamine-induced hepatitis in rats, but there was no direct toxic effect when herbs were administered alone.

Plasma fibronectin is an α₂-glyoprotein, which is produced by vascular endothelial cells. Raised level of plasma fibronectin has been observed in diabetic patients particularly in the presence of microvascular complications. However, no available data exist about urine level of this glycoprotein in diabetic patients. We measured urine fibronectin level by ELISA methods in 54 diabetic patients who have microvascular comlications or not. The following results were obtained. 1) Urine fibronectin level(㎍/g creatinine) in diabetic group(1740.0±678.0) is increased compaired with those in normal control group(471.0±59.0). but this results were not significantly different among two groups(P>0.05). 2) Urine fibronectin level(㎍/g creatinine) was significantly increased in patients with nephropathy (6188.0±3144.0) compared with those in normal control group(471.0±59.0) and patients without nephropathy(645.0±251.0)(P<0.001). 3) There were a significant correlation between BUN, creatinine, creatinine clearance, 24hr urine total protein and urine fibronectin level in diabetic patients. Our data suggest that urine fibronectin excretion level might be used as a sensitive guide for diabectic nephropathy.

Background/Aims: Chronic obstructive pulmonary disease (COPD) is less prevalent in females than males, but it affects mortality in females. There may be sex differences in the clinical characteristics of COPD. Methods: We analyzed the Korea National Health and Nutrition Examination Survey dataset from 2007 to 2018. We compared the clinical characteristics and comorbidities in subjects with COPD according to sex. We adjusted the multivariate logistic regression of lung cancer prevalence according to COPD and sex by age and smoking amount. Results: Females with COPD tended to be older than males with COPD (64.1 ± 0.4 yr vs. 62.3 ± 0.2 yr, respectively, p < 0.001). Approximately 89% of males with COPD had a smoking history, while 86% of females with COPD were non-smokers (p < 0.001). Household income was lower (p < 0.001) and asthma and overall malignancy were more prevalent in females with COPD than males with COPD (25.5 vs. 11.6%, respectively, p < 0.001; (6.3 vs. 5.4%, respectively, p < 0.001). However, lung cancer was more common in males with COPD than females with COPD (0.9 vs. 0.1%, respectively, p < 0.001). Lung cancer prevalence increased in males with moderate COPD compared to subjects without COPD (OR, 4.409; 95% CI, 1.741–9.419). Conclusions: Females with COPD had a lower smoking rate, household income, and lung cancer prevalence than males with COPD. More active COPD screening is needed for women of low socioeconomic status, even if they do not smoke.

Inhibition of acetylcholinesterase (AChE) is one of the important modes of action available for the control of insects. An assessment was made of the electric eel AChE inhibitory activity of 55 endophytic fungi isolated from the leaves of Huperzia serrata collected in Eunshi, Hubei Province, China. Of 55 mycelial extracts and 55 ethyl acetate-soluble fractions from liquid culture of the fungi, the ethyl acetate-soluble fraction of strain ES056 exhibited strong AChE inhibitory activity (88%) at a concentration of 100 μg/mL. Based on morphological characteristics and nuclear ribosomal DNA ITS sequence analysis, this fungus showed greatest similarity to members of the order Eurotiales and was shown to be most closely related to members of the Aspergillus aculeatus group. It was designated Aspergillus sp. MY056. This strain merits further study as a potential anti-AChE product.

Lymphangioma is an abnormal collection of congenitally isolated lymphatic system, which is found mostly in early childhood. Although this may occur in any part of the body mainly including the head, neck, axilla and abdomen, there are rare reports about mediastinal lymphangioma especially in old age. We hereby report a case of solitary mediastinal lymphangioma con. rmed pathologically in a 66-year-old woman. A 66-year-old woman who underwent a kidney transplant surgery 20 years ago was referred to pulmonary division because of a newly developed right upper mediastinal nodule on simple chest X-ray, which was not shown one year ago. She had no symptoms such as cough, dyspnea and chest pain. She was a never smoker. Chest computed tomography (CT) scan demonstrated about a 25mm well-de. ned low density nodule at right upper anterior mediastinum. Initial impression of CT scan was a benign cystic mass, such as bronchogenic cyst, or cystic change of neurogenic tumor. We observe her for 1 year. Because size of the nodule increased from 25 to 34mm in follow-up chest CT scan compared with previous CT scan. Therefore anterior mediastinal tumor was completely resected by video-assisted thoracosopy. Its immunohistochemical stain revealed positive for D2-40 and CD31, which supported the histological diagnosis of cystic lymphangioma. We report the 3rd case of solitary mediastinal cystic lymphangioma in Korea as it is an extremely rare lesion in old age. This can contribute to literature due to its rarity and unusual location. And we recommend that clinicians should consider cystic lymphangioma as a possible diagnosis for the patients with increasing mediastinal mass asymptomatically.
