본 연구의 목적은 대전광역시 도시림의 산림식생을 대상으로 2009년 5월부터 9월까지 식물사회학적으로 조사를 하고, 식물군락의 종조성과 종간 상관관계를 구명하여 도시림 보전과 관리 및 산림휴양에 필요한 기초자료의 제공목적에 바탕을 두었다. 이를 위하여 대전광역시 도시림의 산림 일대 101개소의 산림식생자료를 토대로 cluster 분석과 Z-M 식물사회학적방법에 의해 식생유형분류를 수행하였던 바 총 6개의 식생단위로 분류되었으며, 일본잎갈나무 군락, 졸참나무 - 아까시나무군락, 상수리나무군락, 굴참나무군락, 신갈나무군락, 소나무군락으로 분류되고, 군락유사도는 대부분 0.6내외로 나타나 큰 차이가 없는 군락으로 판단되었다. This study was carried out to classify forest vegetation structure of urban forest in Daejeon Metropolitan City from May to September in 2009 using cluster analysis and phytosociological methodology of Z-M school in order to furnish basic materials for forest recreation. Total of 101 plots were investigated in the area. The forest vegetation around Daejeon Metropolitan City was classified into 6 community types such as Larix leptolepis community, Quercus serrata-Robinia pseudo-acacia community, Quercus acutissima community, Quercus variabilis community, Quercus mongolica community and Pinus densiflora community. According to the result of community coefficient of similarity analysis, the index was approximately 0.6 which meaned similar communities each other.

The purpose of this study was to obtain the demographic and clinical characteristics of hospitalized methamphetamine abuse or dependent patients at National Bugok Hospital. The study subjects were 52 hospitalized male patients who met the DSMIV criteria for methamphetamine abuse or dependence. Two psychiatrists of National Bugok Hospital obtained basic data of the patients. The survey questionnaires had components that could inform clinical data of the patterns and typical problems associated with methamphetamine use. The average age of the study subjects was 37.6 years. The majority of patients were in their 30s (67.3%) and 40s (26.9%). High school graduation was the most common education achievement level. Individuals who had higher education levels tended to start taking methamphetamine earlier and admit themselves to hospitals voluntarily. It took 6.8 years from the start of methamphetamine use for users to be arrested and 10.4 years for them to admit themselves for treatment. After injecting methamphetamine, most of the study subjects indulged in risky behavior such as reckless sexual contact and driving. Because of methamphetamine users’ conviction about having control over the drug and denial of drug-related problems, they are unable or unwilling to recognize the problematic nature of the drug. The government must provide education programs on the related problems of methamphetamine use and provide treatment facilities for users.

This study was conducted to describe forest stand characteristics of the habitats of Allium victorialis var. platyphyllum population from the ecological analysis of classification of vegetation types, importance values, species diversity, interspecific association and community similarity in Ulleung Island and Mt. Hambaek, in which investigated by 48 plots (10 m×10 m). The vegetation studied was classified into 1 community group, 2communities, 2 groups and 3 subgroups for a species unit and divided by 5 units for a vegetation unit. In the Fagus engleriana group (vegetation unit 1, 2 and 3), importance value of A. victorialis var. platyphyllum in herb layer showed relatively higher value than other units. Importance value of A. victorialis var. platyphyllum in herb layer had higher value. In the analysis of interspecific association, most of the species associated positively to A. victorialis var. platyphyllum belonged to habitat features of valley area and sub-alpine zone. Therefore, it was considered that the growing environment of A. victorialis var. platyphyllum population was closely correlated to soil moisture and air humidity.

본 연구는 산마늘 개체군 자생지의 소산 식물상을 밝히기 위하여, 2009년 3월부터 2010년 6월까지 총 4차례의 현지조사를 통하여 조사한 결과, 관속식물은 3문 2강 32목 64과 142속 181종 2아종 30변종 1품종으로 총 214분류군(taxa)으로 파악되었다. 특정식물종 중 I등급 식물이 15과 16속 15종 2변종 17분류군, Ⅱ등급 식물이 13과 15속 14종 2변종 16분류군, Ⅲ등급 식물이 16과 19속 18종 2변종 20분류군, Ⅳ등급 식물이 20과 23속 19종 4변종 23분류군, Ⅴ등급 식물이 2과 2속 2종 2분류군으로 총 78분류군이었다. 희귀식물은 9과 11속 10종 2변종 12분류군이었으며, 특산식물은 17과 19속 18종 3변종의 21분류군으로 조사되었다. 조사지역 내 멸종위기식물은 출현하지 않았고, 귀화식물과 생태계교란식물이 나타나지 않은 것으로 보아 생태계가 안정되고, 생태적 위해성의 우려는 없는 것으로 판단되었다. 또한 산마늘 개체군 자생지에는 개다래, 층층나무, 만병초, 마가목 등 계곡성 및 고산성식물종이 주를 이루는 생육환경을 나타내고 있었다. This study was conducted to investigate the flora of habitats distributed with Allium victorialis var. platyphyllum populations in the South Korea. The vascular plants were surveyed 4 times from March 2009 to June 2010. The flora of studied area was listed as 214 taxa; 64 families, 142 genus, 181 species, 2 subspecies, 30 varieties, 1 forma. According to the specific plant species by classes, class Ⅰ has 17 taxa; 15 families, 16 genus, 15 species, 2 varieties. Class Ⅱ has 16 taxa; 13 families, 16 genus, 15 species, 2 varieties. Class Ⅲ has 20 taxa; 16 families, 19 genus, 18 species, 2 varieties. Class Ⅲ has 20 taxa; 16 families, 19 genus, 18 species, 2 varieties. Class Ⅳ has 23 taxa; 20 families, 23 genus, 19 species, 4 varieties. Class Ⅴ has 2 taxa; 2 families, 2 genus, 2 species. Rare plant was 12 taxa; 9 families, 11 genus, 10 species, 2 varieties. Endemic plant was 21 taxa; 17 families, 19 genus, 18 species, 3 varieties. Endangered plant was not present in study area. It was considered that the ecosystem was probably stabilized for nothing of naturalized species and ecosystem disturbance species there. The characteristics of growth environments in the habitats with Allium victorialis var. platyphyllum were considered to be related to valley species and subalpine species such as Actinidia polygama, Cornus controversa, Rhododendron brachycarpum and Sorbus commixta.

Tracheal intubation is the most common cause of Tracheal stenosis. The treatment of trachea stenosis vary according to site or size of tracheal stenosis. Thirty six age old man was transferred our hospital for evaluation of dyspnea. Subglottic stenosis was shown on bronchoscopy & chest computerized tomography(CT) scan of neck. Balloon dilatation was performed and then patient breathed at ease. Tracheal resection and end-to-end anastomosis was applied to repetitive tracheal stenosis. Balloon dilatation before surgical management makes better respiratory difficulty. We report succesful application of surgical management after balloon dilatation in repetitive tracheal stenosis patient. We will suggest that the balloon dilatation improve symptoms before tracheal resection and end-to-end anastomosis or stent, if sugery or stent insertion are not applicable due to poor status of patient.

Background: Evidence has accumulated that opioids can produce potent antinociceptive effects by interacting with opioid receptors in peripheral tissues. Bupivacaine has a potent analgesic effect with early peak onset in the postoperative period. The combination of intrapelvic bupivacaine and morphine has been suggested as an ideal analgesic after endoscopic pelvic surgery. Methods: Sixty patients scheduled for endoscopic pelvic surgery under general anesthesia were allocated randomly to three groups. Group 1 received normal saline 20 ml, group 2 received morphine 5 mg in normal saline 20 ml, and group 3 received morphine 5 mg in 0.25% bupivacaine 20 ml into the pelvic cavity. Postoperative pain was assessed using the visual analogue scale at 1, 2, 4, 8, and 24 hours after the intrapelvic instillation. Supplemental analgesic requirements, vital signs, and side effects were recorded for 24 hours. Results: Intrapelvic morphine and bupivacaine produced significant analgesia after endoscopic pelvic surgery. The patients in group 3 bad lower pain scores than those in the group 1 and 2 at 1, 2 and 4th hours. There were no significant differences in the pain scores at 8 hours and 24 hours postoperatively between group 2 and 3. Supplemental analgesic requirements were significantly greater in the groups 1 and 2 than the group 3 for 24 hours. No significant side effects occurred. Conclusion: The intrapelvic instillation of morphine and bupivacaine is effective for the postoperative pain control in patients undergoing endoscopic pelvic surgery.
