본 연구는 독립훼손지 중 아고산대에 위치한 지리산국립공원 세석평전과 노고단 복원식생지를 대상으로 현존식생 분석 및 식생분포 특성을 파악하여 중장기적인 모니터링 및 관리방안 수립을 위한 기초자료를 제공하고자 수행하였다. 현존식생 조사범위는 훼손지 일대 유역권분포 현황을 고려하여 설정하였으며, 세석평전 조사면적은 55,037㎡, 노고단 조사면적은 166,599㎡ 이었다. 세석평전은 초본층에 의한 식생피복도는 90% 이상 수준으로서 나지노출이 없었고, 관목층의 피복도가 60% 이상으로 안정화되어 있었다. 주요 출현수종은 구상나무, 사스래나무, 쇠물푸레나무, 철쭉, 털진달래, 붉은병꽃나무 등 식재수종과 자연적으로 이입한 자생수종이 생육하고 있었다. 노고단은 신갈나무, 호랑버들, 철쭉, 털진달래, 미역줄나무 등이 우점하는 관목식생지가 52%로 가장 넓게 분포하고 있었고, 전반적으로 식생활착 상태가 양호하였다. 노고단의 원식생은 신갈나무군락으로 추정되었고, 군부대철거지에는 귀화식물이 분포하고 있기 때문에 적극적인 관리가 필요하였다. 연구대상지는 장기적으로 주변 자연식생과 조화로운 식생경관으로 발달할 것으로 예측되었다. 향후 훼손지 복원모델은 인근 지역의 원식생을 고려하여 설정해야 할 것이지만, 복원 달성 목표는 실현가능한 수준의 목표를 설정해야 할 것이다. This study was conducted to provide basic data for mid-to long-term monitoring and establishment of management plans by analyzing the existing vegetation and identifying the vegetation distribution characteristics for the restored vegetation in Nogodan and Seseokpyeongjeon in Jirisan National Park located in the subalpine zone among the independent damaged areas. Actual vegetation survey range was established in consideration of the distribution of the watershed around the damaged area. The surveyed area of Seseokpyeongjeon was 55,037㎡, and the surveyed area of Nogodan was 166,599㎡. In Seseokpyeongjeon, the vegetation coverage by the herbaceous layer was almost 90% or more, there was no bare exposure, and the coverage of the shrub layer was stabilized at 60% or more. The main emerging tree species were planted species such as Abies koreana, Betula ermanii, Fraxinus sieboldiana, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Weigela florida as well as natively migrated native species. In Nogodan, the shrub vegetation dominated by Quercus mongolica, Salix caprea, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Tripterygium regelii was the most widely distributed with 52% of the area, and the overall diet was good. The native vegetation of Nogodan was presumed to be a cypress colony. Naturalized plants were distributed in the military base demolition site, so active management was required. The study site was predicted to develop into a vegetation landscape in harmony with the surrounding natural vegetation in the long term. In the future, the restoration model for damaged areas should be set in consideration of the native vegetation of the nearby area, but the goal to achieve restoration should be set at a feasible level.

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.

Background: Intratumoral injection of OK-432 produced significant antitumor effects. There are reports that OK-432 was injected directly into tumor tissue on gastrointestinal tracts and HCC tissue, producing decrease in serum alpha-fetoprotein level. We adopted this technique for treating locally advanced lung cancer. The object of this study is to evaluate the local therapeutic efficacy, side effects of injection for treating symptomatic mass. Methods: Twenty lung cancer patients (13 males and 7 females) underwent sonography guided OK-432 injection. We analyzed relationships between response of OK-432 and response of skin test, histology and age. Pain that patients feel was evaluated by VAS (Visual Analog scale). Results: A significant decrease of tumor size was observed. The mean pre-injection diameter of the lesions was 54.7±11.3mm, PR rate were 15.0% (3/20) and minimal change (50%<tumor size decreased.) patients were 35.0% (7/20). The VAS score before injecting OK-432 into the lesion was 5±3, this was decreased to 2.5±1.5 (p=0.04). Object response was significantly correlated with skin response, adenocarcinoma, and age. Conclusion: A significant decrease of tumor size and pain was observed. So OK-432 is a valuable treatment option for patients with symptomatic lesion from advanced lung cancer who are not amenable to further therapy.

핵연료의 재처리공정중에서 방출되는 high-level방사성폐액을 안정한 글라스형태로 고화하여 처리하는 글라스고화법이 사용되고 있다. 본 연구에서는 고화글라스구성성분의 하나인 Pb가 글라스의 용해도, 글라스중에서의 존재형태, 결정화에 미치는 영향을 UV, XRD, TG등을 이용하여 검토하였다. Pd의 용해도는 Tg∼1200℃에서 수 십-수 백ppm정도이며, 용해도를 전후하여 각각 2가이온 및 콜로이드상태로 존재한다는 것을 확인하였다. 그리고 Pb는 결정화에있어서 결정화를 촉진하였으나, Mn, Cr, V, Sb등의 다원자가원소의 첨가에 의하여 결정화를 억제할 수 있었다. Glass is an attractive form for the permanent and secure disposal treatment of high-level radioactive liquid wastes from high-level nuclear waste re-management process. In present work, we investigated the effect of glass solubility, existing form from of Pd in glass, and crystallization of glass on the Pd behaviour in the waste glass using UV, XRD, and TG. The solubility of Pd was from several 10s to several 100s ppm in Tg∼1200℃, and we found Pd exists as bivalent ionic or colloidal form at around the value of Pd-solubility in glass matrix. In crystallization, Pd in glass was helpful for promoting the crystallization, but Mn, Cr, V, and Sb additives retarded and controlled the crystallization.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

We fabricated a-Si : H/a-SiN : H superlattices using the RF glow discharge system which was equipped with sliding mask and liquifing system of exhausting gases. Samples were deposited at substrate temperature of 250℃, deposition rate of 0.8 - 1.0 A˚/sec, deposition pressure of 200 mTorr (SiH_4) and 400 mTorr (SiH_4 + NH_3), and Rf power density of 150-200 mW/㎠. Employing a-Si: H layer thickness as a deposition parameter (fixing a-SiN : H layer at 30A˚), we found that the decrease of a-Si : H layer thickness (600→60A˚) was accompanied with the increase of activation energy (0.8→1.0eV). And in particular, persistent photoconductivity was clearly observed in the samples with 60A˚ a-Si :H.
