생태복지는 인간의 복지와 건강한 생태계의 상호관계성에 대한 국제적 담론에서 시작되었다. 본 연구는 국립공원이 생태복지의 최대 실현가능 지역이라는 점에서 국립공원에 적합한 ‘국립공원 생태복지’ 개념을 정립하고 정책방향을 설정함으로써 향후 국립공원에서의 생태복지 실현을 도모하기 위한 기초자료를 제공하는데 그 목적이 있다. 이를 위해 사전워크숍과 총 2회에 걸친 델파이 조사를 수행하였다. 본 연구를 통해 ‘국립공원 생태복지’는 국립공원에서 생태계의 지속가능성과 생물다양성을 유지하며, ‘국립공원 인간복지’와 ‘국립공원 생태계복지’의 조화를 지향하는 복지로 정의되었다. 2차 델파이 결과 모든 항목에서 평균 4.00 이상, 내용 타당도(CVR) 0.37 이상, 변이계수(CV)0.5 미만으로 타당한 내용으로 확인되었다. 국립공원 생태복지의 정책방향을 설정하기 위해 생태복지의 바탕이 되는 생태계서비스의 요소들 중 국립공원에 적합한 주요 요소를 도출한 결과 공급서비스에서 먹이·식량, 물, 유전자원 3항목, 조절서비스와 기반(서식지)서비스의 모든 항목, 문화서비스에서 미적정보, 휴양관광, 심신치유, 지식체계ㆍ교육적가치 4항목이 최종 도출되었다. 또한 본 연구에서는 국립공원 생태복지의 개념과 향후 국립공원 생태복지 정책이 어떻게 나아가야할지 방향성을 제시하였다. 그러나 이를 실현하기 위해서는 향후 이에 대한 구체적인 단위사업에 대한 실행계획이 수반되어야 하며 이를 위한 추가적인 연구가 필요할 것이다. The concept of Eco-welfare emerged in the process of discovering the relationship between a healthy ecosystem and human wellbeing. The objective of this study is to offer basic data for eco-welfare policy realization by conceptualizing the ‘National Park Eco-welfare’ since national parks are appropriate places for eco-welfare to be optimally implemented. A pre-workshop and two rounds of Delphi surveys were conducted to determine the concept of the ‘National Park Eco-welfare ’ and the main elements to be included in ecosystem service. Through this study, the concept of ‘National Park Eco-welfare’ was defined as efforts to conserve the biodiversity and sustainability of the ecosystem and create harmony between ‘National Park Ecosystem Welfare’ and ‘National Park Human Welfare’. To establish the direction of the National Park Eco-welfare policy, we identified the main elements of ecosystem services which are appropriate for the National Park. These are comprised of 3 elements (food, fresh water and genetic resources) from supply service, all elements from regulating service and supporting/habitat service and 4 elements (aesthetic information, recreation-based ecotourism, healing, and knowledge systems with educational values) from culture service. In this study, the concept of National Park Eco-welfare was established, and its policy objectives and scope were suggested. However, further studies are necessary to develop action plans areand thereby realize the policy.

Background: Propofol has an antioxidant capacity and can be used for ischemia-reperfusion injury of the liver. However, the effects of propofol on the Kupffer cells have not been establisked. Methods: Kupffer cells were isolated and cultured from male Sprague-Dawley rats. The effects of propofol on the Kupffer cells were evaluated by a phagocytosis assay, TNF-α gene expression, and superoxide anion release after administering propofol in different concentrations on the cultured Kuprrer cells. Results: The latex bead phagocytosis by the Kupffer cells was suppressed when the Kupffer cells were exposed to propofol irrespective of concentrations. Higher propofol concentrations decreased the loss of Kupffer cells after latex bead phagocytosis. Propofol induced TNF-α mRNA expression in the Kupffer cells, but the mRNA expression level after 50㎍/ml of propofol decreased. The pattern of TNF-α mRNA expression induced by propofol was different to that induced by LPS: TNF-α mRNA was expressed continuously in the propofol-treated cells until 16 hours after exposure to propofol, whereas the level of TNF-α mRNA expression induced by LPS was evident after 2 hours and was not found thereafter. TNF-α production after propofol treatment was not higher than that of the control. Formazan presipitation did not show any qualitative differences between cells untreated or treated with propofol concentrations of 0.5, 5.0, and 50 ㎍/ml. Conclusions: These results showed that propofol might inhibit Kupffer cells. This suggests that propofol and be used for patients with ischemia-reperfusion injury of the liver.

Clinical effects of rhG-CSF were investigated in 17 patients receiving chemotherapy for non-Hodgkin's lymphoma. Patients were given G-CSF 2㎍/㎏/day after 2nd cycle chemotherapy for least 14 consecutive days, and clinical and laboratory results were compared to results of the first cycle. Treatment with G-CSF resulted in increase of mean WBC count(952.9±152.2㎜³vs 1882.4±350.4/㎜³) and neutrophil count(212.9±53.0/㎜³vs 841.5±238.0/㎜³), reduced the duration of leukocytopenic days(12.4±1.3 days vs 5.5±1.0 days, WBC count less than 4000/㎜³) and neutropenic days(4.5±0.9 days vs 2.3±0.7 days, neutrophil count less than 500/㎜³), and reduced the duration of neutropenic fever(5.8±1.1 days vs 0.9±0.5 days). The side effects of G-CSF were not so significant. These results demonstrated that G-CSF is safe and useful for the treatment of neutropenia induced by anticancer chemotherapy of non-Hodgkin's lymphoma and reducing the incidence of febrile periods and duration of antibiotic administration.

Objectives : Cinnamomi Ramulus (CR), the young twing of Cinnamomi loureirii nees, has been used for treating symptoms related to pain. rheumatic arthritis and inflammation in Korean herb medicine. This study was carried out to investigate the anti-inflammatory effect of CR in vivo and in vitro. Methods : Extracts of CR were prepared and the chemical components of the extracts were examined by gas chromatography-mass spectrometry (GC-MS). The extracts were administrated to the rat paw edema model induced by carrageenan to evaluate the anti-inflammatory effect of CR. The expressions of nitric oxide (NO). prostaglandin E2(PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were also quantified in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages to survey the effect of CR in vitro. The main components were cinnamaldechyde and coumarin. Results : We examined the anti-inflammatory activity of the 80% ethanol extract of Cinnamomi Ramulus in vivo by using carrageenan-induced rat paw edema model. Maximum inhibition of 54.9% was noted at the dose of 1000㎎/㎏ after 2 hours of drug administration in carrageenan-induced rat paw edema and this showed a potent anti-inflammatory effect. Conclusions : The results showed that Cinnamomi Ramulus suppressed dose-dependently LPS-induced NO production in RAW 264.7 macrophages and also decreased iNOS protein expression. Cinnamomi Ramulus also showed a significant inhibitory effect in LPS-induced PGE2 production and COX-2 expression.

This study was carried out to evaluate performance of sewage treatment facility in rural area. Average effluent concentration was 7.6㎎/1 BOD. 10.3㎎/1 COD, 4.7㎎/1 SS, 19.140㎎/1 TN, and 1,631㎎/1 TP, within discharge quality standard. The removal efficiency rate of BOD, COD and SS was good as 89.8%. 78.5% and 90.1%, respectively. But that of TN, TP was very low as 25.0% and 31.4% respectvely. Average sewage flow rate was investigated by about 1.1㎥/d per household, 398ℓ pcd. In rainfall period, the removal efficiency rate of BOD. TN and TP was very low as 15%, 22% and 28%, respectively because of inflow and infiltration into sewer. In flowing concentration of sewage was diluted as rain is inserted into sewer and submerged facility was not operated at normal condition. Therefore it is required that the sewer will have to repair and hydraulic design for facility will have to be check. So it is necessary to support systematical, administrative measures for responsible management.
