The purpose of this study is to analyze the conservation management and using development of the Moak-san provincial park with special regards to natural and cultural environment. Recently, with the rapid increase of use about national and provincial parks as a area of outdoor recreation, our natural park faces a serious environmental problems. So the quality of outdoor recreation has been decreased. Therefore, The conservation methods of natural park and resourse are very important for the maintenance of natural and cultural environment. Kumoh-san was appointed at first as a provincial park in 1970. And 20 provincial parks are present now in Korea. Moak-san provincial park extends over 2 Shis and 1 Gun including Kimjea-Shi(28.22㎢), Wanju-Gun(10.69㎢) and Chonju-Shi(3.31㎢). It's location is at 127˚ 02' E and 35˚42' N. In its climate, the annual mean precipitation is 1134.3mm, and temperature is 12.0∼12.5℃. In this park area, mostly Buddhist cultral asserts are collectively preserved, such as the Kumsansa, Kuksinsa. Soowangsa and Daewonsa. Vegetation of Moak-san was investigated 440 species. The Fegaceae is main species. As remarkable thing of park use, the trail which make an effect on the park resource conservation and effect promotion of park use established but if asked thorohgh management, because of intense gully erosion phenomenon. Recently, in the direction of Kumsansa and Kui project is developing or planning, but in the direction of Chunginri project is not established yet, so we request the valance Moak-san total development pslan. In the development plan, rational harmony of development and conservation was pointed out the essense factor.

The object of this study was to examine the user`s impacts on the environmental deteriorations of trail at Ticket Office - Paekryunsa (Temple) Hyangcho^kpong - Dongyupryung - Chilyun Fall area in To^kyusan National Park. Four trails were sampled in the study area according to the amount of users. Then the user`s impacts on trail were measured at each trail. The Ticket Office-Paekryunsa trail was the mo;;t used district and followed at Paekryunsa-Hyangcho^kpong trail, Hyangcho^kpong-Dongyupryung trail in descending order. Dongyupryung-Chilyun Fall trail is not used by people because of rest rotation system. The entire width of trail was greater at the more heavily used trail. Maximum depth, cross-sectional area loss, and surface texture and roughness of trail were the highest at Paekryunsa-Hyangcho^kpong trail. Soil hardness, soil acidity, soil moisture content, organic matter content, and exchange canon were influenced by trampling. Soil hardness, soil acidity and exchange canon increased in tramples soil, but content of soil moisture and organic matter decreased therein. Environmental deteriorations of trail were significantly influenced by the amount of users and the slope of trail. Bared lands about 2.000㎡ were appeared by trampling and camping around Hyangcho^kpong. Effects of carrying of rest rotation system for National Park were partly recognized at Dongyupryung-Chilyun Fall trail.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

  목적: 양전자방출단층검사(Fluorine-18 2-Deoxy-D-Glucose positron emission tomography: ¹?F-FDG PET)는 가시적 영상분석과 반정량적 섭취계수 분석 방법을 사용하여 폐의 염증성 질환과 폐암을 구별 및 진단하는 데 유용하다. 일반적으로 표준화섭취계수(Standardized Uptake Value: SUV)가 폐 질환의 진단에 사용되지만, 이는 폐 조직에 있어서 반정량적, 정량적 분석을 통한 동적인 정보를 포함하지 않는다. 그러므로, 본 연구는 ¹?F-FDG PET 검사에서 폐 질환의 동적 섭취 분석이 보다 정확한 대상질환의 진단을 유용하게 할 수 있을 것이라는 가정하에 시간-방사능 곡선(Time-Activity Curve: TAC), 표준화섭취계수-동적곡선(Standardized Uptake Value-Dynamic Curve: SUV-DC), 패트락 분석법(Patlak analysis: Glucose Metabolic Rate(MRGlu))을 토대로 얻은 분석방법을 이용하여 진단적 유용성을 평가하였다.<BR>  대상 및 방법: 폐 질환을 가진 17명의 환자를 대상을 하여, 각각 60분간 Dynamic ¹?F-FDG PET검사를 시행하였다. 획득한 정보를 통하여 폐질환의 형태를 따라 관심영역(Region of Interest: ROI)를 그린 후, 반정량적 분석인 TAC, SUV-DC와 정량적 분석인 Patlak analysis를 각각의 군에 따라 분석하여 비교 분석하였다.<BR>  결과: Dynamic ¹?F-FDG PET을 통한 분석결과, TAC 형태는 초기 혈류상에서 폐의 염증성 질환과 폐암의 구분이 어려웠으나, 시간이 지날수록 폐암의 곡선이 염증성 질환의 경우보다 확연히 증가하였다. SUV-DC의 경우는 TAC 형태와 거의 유사한 형태를 가졌다. Patlak analysis 분석결과, 대동맥 영역에서는 폐의 염증성 질환이 폐암보다 높은 혈액 방사능을 보였으나 시간이 지남에 따라 염증성 질환의 혈액 방사능이 극히 낮아졌다. 반면, 병변 조직에서는 폐암이 가장 높은 섭취를 보였으며 폐의 염증성 질환은 중간 정도에 머물렀다.<BR>  결론: TAC와 SUV-DC 분석에서 폐암과 폐의 염증성 질환은 각각 고유한 그래프 형태를 띠었으며 Patlak analysis에서 역시 주목할 만한 차이를 보였다. 따라서 이러한 분석법을 토대로 좀더 깊이 있는 연구가 진행된다면 비침습적으로 폐의 질환을 구별하는 데 보다 적절하고 유용한 진단적 정보를 얻을 수 있을 것이다.   Purpose: The diagnostic utility of fluorine-18 2-deoxy-D-glucose positron emission tomograhpy (¹?F- FDG PET) for the non-invasive differentiation of focal lung lesions originated from cancer or inflammation disease by combined visual image interpretation and semi-quantitative uptake value analysis has been documented. In general, Standardized Uptake Value(SUV) is used to diagnose lung disease. But SUV does not contain dynamic information of lung tissue for the glucose. Therefore, this study was undertaken to hypothesis that analysis of dynamic kinetics of focal lung lesions base on ¹?F-FDG PET may more accurately determine the lung disease. So we compared Time Activity Curve(TAC), Standardized Uptake Value-Dynamic Curve(SUV-DC) graph pattern with Glucose Metabolic Rate(MRGlu) from Patlak analysis.<BR>  Methods: With lung disease, 17 patients were examined. They were injected with ¹?F-FDG over 30-s into peripheral vein while acquisition of the serial transaxial tomographic images were started. For acquisition protocol, we used twelve 10-s, four 30-s, sixteen 60-s, five 300-s and one 900-s frame for 60 mins. Its images were analyzed by visual interpretation TAC, SUV-DC and a kinetic analysis(Patlak analysis). The latter was based on region of interest(ROIs) which were drawn with the lung disease shape. Each optimized patterns were compared with itself.<BR>  Results: In TAC patterns, it hard to observe cancer type with inflammation disease in early pool blood area but over the time cancer type slope more remarkably increased than inflammation disease.<BR>  SUV-DC was similar to TAC pattern. In the result of Patlak analysis, In time activity curve of aorta, even though inflammation disease showed higher blood activity than cancer, at first as time went by, blood activity of inflammation disease became the lowest. However, in time activity curve of tissue, cancer had the highest uptake and inflammation disease was in the middle.<BR>  Conclusion: Through the examination, TAC and SUV-DC could approached the results that lung cancer type and inflammation disease type has it’s own difference shape patterns. Also, it has outstanding differentiation between cancer type and inflammation in Patlak and MRGlu analysis. Through these analysis methods, it will helpful to separation lung disease.

Spontaneous esophageal rupture (Boerhaave's syndrome) is a rare case that require early diagnosis and treatment because of its high mortality. The oral administration of osmotically balanced polyethylene-glycol-based electrolyte preparation is a commonly prescribed preparation for cleansing in patients undergoing colonoscopy. Nausea, vomiting and abdominal pain are frequently seen, but serious adverse reactions are rare. Esophageal rupture secondary to severe vomiting, which occurred during colonoscopy preparation using polyethylene gIycoI(PEG) electrolyte solution is extremely rare and only few cases have been published in the literature. We report a case of spontaneous esophageal rupture after routine administration of the PEG before colonoscopy. 대장 정결을목적으로 PEG 사용 후 아주 드물게 발생하는 Boerhaave 증후군 1예를 경험하였기에 보고하는 바이다.

대장 지방종은 주로 우측 결장에 호발하고 특히 회맹판 부위와 맹장 부위에 호발한다. 또한 50~60대에 빈도가 높고 증상이 있는 환자에서 장중첩증이 높게는 40~50%에서 보고되고 있어 성인 장중첩증의 원인으로 중요한 비중을 차지한다. 특히 성인 장중첩증 및 장폐쇄의 중요 원인인 악성 종양과 임상 양상이 유사하여 감별진단이 중요하다. 저자들은 반복적인 복통을 주소로 내원한 환자에서 맹장의 4×5㎝의 점막하 지방종이 말단 회장부위와 반복적인 장중첩중이 발생했던 1례를 부분 절제술로 치료하여 양호한 임상 경과를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Lipomas are one of the most common benign nonepithelial tumors of the colon which are often detected incidentally by radiologic investigation or on operation. These tumors are usually without specific symptoms. Colonic lipomas occur most often in the right colon, particularly in the ileocecal valve and the cecum. Most patients are asymptomatic. but tumors larger than 2 cm tend to produce a change in bowel habit. abdominal pain. rectorrhagia and complications including luminal obstruction or intestinal intussusception. Diagnosis can be made by colonoscopy abdominal CT. MRI, or barium enema. We report a case of lipoma of the cecum that originated in the submucosa and presented as a intussusception in a 50-year-old woman with a brief review of the literature.

Characterization of Artificial Graphite Electrodes

Sei-Min Park,Sang-Moo Han,Seh-Min Oh 한국탄소학회 2000 Carbon Letters Vol.1 No.2

Physical properties of artificial graphite electrodes were evaluated along three different directions; circumferential (X), radial (Y), and axial (Z) directions. Four kinds of commercial electrode products were used in this study for the evaluation; pole (AP) and nipple (AN) of manufacturer A, pole (BP) and nipple (BN) of manufacturer B. The mechanical, electrical, and thermal properties in X and Y directions were very similar to each other. In Z direction, however, the mechanical properties, including flexural strength and compressive strength, were higher, and electric resistance and thermal expansion were much lower than those in the other directions. The microstructures observed by optical microscope and scanning electron microscope revealed that the differences in properties by the measuring direction were caused by the preferential alignment of needle cokes along the Z direction. When comparing the properties of the electrode samples in the same direction, the mechanical properties mainly depended on the bulk density or porosity of the samples as well as preferential alignment of needle cokes.
