  • 낙동정맥 절구골의 식생구조를 파악하고자 계곡부 약 3km 구간을 대상으로 $10m{\times}10m(100m^2)$ 조사구 29개소를 설치하여 식물군집구조 조사를 실시하였다. TWINSPAN classification에 의한 군락 분류 결과 소나무군락, 낙엽활엽수군락, 굴참나무군락, 신갈나무군락, 일본잎갈나무군락 5개 유형으로 분류되었다. 계곡부와 북사면에는 습윤지성 낙엽활엽수와 참나무류가 주로 분포하였고 일본잎갈나무군락은 당분간 현상태를 유지하겠으나 하층의 들메나무, 산뽕나무, 고로쇠나무 등 낙엽성 활엽수의 세력이 우세해지고 있어 장차 이들 종으로의 천이가 기대되었다. 군락별 종다양도지수는 0.9665~1.2450 범위로 낙동정맥 타 지역에 비해 높은 것으로 나타났다.

  • 들메나무군집의 식생구조를 밝히기 위하여 민주지산지역의 해발 700~1,100m 사이 계곡부에 10m*10m 면적의 조사구 20개를 설정, 조사하였다. 전체 조사구에 대해 classification 기법중 TWINSPAN을 이용한 결과 6개의 군집으로 분리되었으며, 각 군집별로 종조성을 살펴본 결과 민주지산 지역의 들메나무군집은 신갈나무군집에서 천이가 진행되어 온 것으로 판단되며, 까칩가달, 고로쇠나무, 층층나무 등이 부수종을 이루고 있으나 경쟁수종이 형성되어 있니 장ㄴㅎ아 토지극상림으로 판단되었다. 흉고직경급별분석에서 들메나무는 전층위에서 고르게 출현하고 있고, 군집이 안정되어 있어 종다양도(Shannon's index 0.72~0.82)가 낮게 나타났으며, 각 조사구당 평군종수는 11.0종, 평균개체수는 111.5주였다.

  • The moor vegetation of Daeryong-po on Mt. Daeam, east-central Korea was investigated in July 26th-29th, 1989, It was classified into I community group, 4 communities and 5 subcommunities; Sanguisorba tenuifolia var. alba community group, Sphagnum palustre community. Typical subcommunity, Eleocharis mamillata var. cyclocarpa subcommunity, Carex canescense subcommunity, Carex dispalata community, Spiraea salicifolia community, Geranium eriiostemon var. megalanthum community, Arundinella hirta-Phragmites communis subcommunity, Angelica purpuraefolia subcommunity. According to this classification, the actual vegetation map was made. The distribution of vegetation in this moor was divided characteristically into two areas. One was a typical oligotrophic area characterized by S. palustre community. The other was an area having mesotrophic or eutrophic conditions where its original state was disturbed by inflow of soil particles and removal of peat. It this disturbed area, C. dispalata, S. sibiricus, G. eriostemon var. megalanthum, were invaded.

  • This study was conducted to evaluate the health status of staff by medical examination data according to the work classification as professional, office worker and laborer in K University in Seoul, Korea. Two thousand four hundred and eighty-four staff (men : 1154, female: 1330) from the university were studied for this report. The anthropometric (height, weight and BMI) and blood pressure (systolic, diastolic) and biochemical parameters (hemoglobin, glucose, cholesterol, AST, ALT) were measured. All groups were calculated using GLM multivariate analysis for three groups after adjustment for age. The average BMI was significantly higher in laborers than professionals and officers after adjustment for age. In blood pressure, especially in SBP, the significant difference was found in females according to the job classification. Blood glucose levels of female laborers were significantly higher than those of officers and professionals. The level of blood total cholesterol of male professionals was significantly higher than those of laborers. The level of blood total cholesterol of female laborers was significantly higher than officers or professionals. Importantly, significant differences were found in BMI, SBP, blood glucose level and cholesterol level of female staff after adjustment for age. These results showed that there were differences in health subjects of staff according to the work classification. This study would provide basic data to prepare the program of health promotion for the college staff according to work classification. Further research is required to discover factors influencing health promotion of staff in colleges.

  • 본 연구의 목적은 성바오로딸수도회 한국관구가 생산·수집한 기록물의 체계적 관리와 이용을 위해 기록분류체계를 개선하는 것이다. 먼저 성바오로딸수도회의 설립 이념과 한국관구의 연혁을 조사한 뒤 조직의 구조를 파악하고 수도회 기록관리 현황을 조사하였다. 그리고 기록물 분류를 위해 기능과 조직(생산주체), 유형에 따른 분류방법을 채택하였다. 이어서 현재 한국관구에서 사용하는 분류체계의 틀이 되는 총원 역사문서고의 분류체계를 조사하고 기존 한국관구 분류체계에서 개선할 점을 점검하여 수정 보완한 기록분류체계를 제안하였다. 본 연구의 결과는 성바오로딸수도회 기록분류체계 개선에 활용되고 가톨릭 수도회의 분류체계 개발에 기초자료가 될 수 있을 것이다.

  • 본 연구는 강원지역 백두대간 천연림의 군집분류와 천이경향을 추정하기 위해 점표본법을 이용하여 향로봉, 오대산, 석병산, 두타산, 덕항산, 함백산 등 총 6개 지역에서 식생조사를 실시하였다. 조사된 식생자료를 바탕으로 Cluster 분석을 이용하여 6개 지역 총 28개의 군집으로 분류하였으며 군집의 속성을 밝히기 위해 수종구성과 종다양성을 분석하였다. 분류된 28개 군집의 상층 수종구성을 바탕으로 군집의 이름을 명명하였고, 이들 군집을 중생혼합림, 기타활엽수림, 신갈나무군집, 신갈나무림, 소나무-신갈나무군집, 소나무림, 거제수나무군집, 신갈나무-잣나무군집등 총 8개의 산림유형으로 집약하였다. 종다양성지수가 낮은 소나무림, 소나무-신갈나무군집 등은 석병산, 두타산, 덕항산 등과 같이 해발고도 1,000 m 내외의 낮은 지형의 백두대간에 위치하였다. 종다양성지수가 높게 나타난 중생혼합림, 기타활엽수림 등은 향로봉, 오대산, 함백산 등과 같이 해발고도 1,400 m 내외의 비교적 높은 백두대간에 위치하였다. 천연활엽수림 내 신갈나무의 구성비율이 증가함에 따라 종다양성지수가 낮아지는 경향을 나타내었다.

  • This paper is to contribute for management and restoration as a basic study of vegetation structure in Aemirang Hill, Nakdongjeongmaek. To verify the characteristics of vegetation structure, we set up 25 plots($100m^2$). The result of community analysis was used by TWINSPAN classification. The communities were classified 7 types i.e. Quercus variabilis community, Quercus mongolica community, Pinus densiflora community, Pinus densiflora-Quercus mongolica community, Q. mongolica-Quercus variabilis community, Quercus mongolica-Betula davurica community, Larix leptolepis community. Pinus densiflora community and Pinus densiflora-Quercus mongolica community are progressively transforming a Quercus mongolica community that is called Pinus densiflora next succession stage. Whereas the communities that has dominant Quercus variabilis and Quercus mongolica did not appear a next generation succession tree such as Carpinus laxiflora, Carpinus cordata in the under story and shrub layer. Therefore, Aemirang Hill's ecological succession was to maintain the status condition. Aemirang Hill's diversity index is 0.5738 to 0.8906. It were analyzed that diversity index was lower than other places.

  • The purpose of this study was to develop a model of plant management based on Robinia pseudo-acacia forests structure in Bucheon city, Korea. For 38 plots were established in Robinia pseudo-acacia forest of Bucheon city. As a result, Robinia pseudo-acacia community was expected to the proceeded to Quercus spp. community. In addition, the diversity of Robinia pseudo-acacia-Quercus spp. community was analyzed higher than Robinia pseudo-acacia community. Based on the result of forest structure analysis, Quercus spp. community was selected as the goal stage of plant management for Bucheon forests and 22 species that were selected by the importance value analysis, classification and ordination analysis and the correlation analysis were chosen as the ecological approprite species. This study also suggested density control guide line for sucession promotion, which individuals numbers of Robinia pseudo-acacia might be reduced from 50 individuals to 23 individuals by selective cutting in order to keep 65% of total basal area.
