Background:Color M-mode doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study was performed to define the feasibility and value of color M-mode echocardiography for the assessment of left ventricular diastolic function in patients with acute coronary syndrome. Methods:Thirty six patients with acute myocardial infarcion and twenty three patients with unstable angina were included (M/F=41/18, 61±12.2 years). Doppler study was performed using ATL HDI-3000 within 24 hours after the attack. In color M-mode study, ROP was measured with ‘Front wave method’ and ‘Baseline shift method’. The patients were grouped into three groups based on E/A ratio and deceleration time (DT) in transmitral flow and S/D ratio in pulmonary venous flow;Group I = Normal pattern (E/A>1, S/D>1, DT>140 ms), Group II =Impaired relaxation pattern (E/A<1, DT>140 ms) and Group III =Pseudonormal/Restrictive pattern (E/A>1.5, S/D<1, with or without DT≤140 ms). Result:Twenty two, thirty four, and three patients were assigned to Group I, II, III, respectively. The ROP could be measured with ‘Front wave method’ in 50 patients (84.7%), but with ‘Baseline shift method’ only in 19 patients (32.2%). ROP with ‘Front wave method’ was 65±25.7, 61±35.6, 71±35.2 cm/sec in Group I, II, III, respectively. There was no statistically significant difference in the value of ROP between group I and II (p>0.05). Conclusion:The ROP seems not to reflect the diastolic function in acute coronary syndrome,although it is measurable with the ‘Front wave method’ in most cases. The measurement of the ROP with‘Baseline shift method’is not feasible in the patients with acute coronary syndrome. 배 경: 허혈성심질환의 좌심실 이완기능을 평가하는 방법으로 심도자법과 도플러 심초음파 검사가 일반적으로 사용되고 있으나 임상적인 제한점이 적지 않다. 본 연구에서는 급성 관동맥 증후군 환자의 이완기능 장애를 확인하는 방법으로 Color M-mode 도플러 심초음파의 임상 적용 가능성에 대해 알아보고자 하였다. 방 법: 급성 관동맥 증후군으로 본원을 방문한 환자 가운데 간헐파형 도플러검사상 승모판 혈류검사와 폐정맥 혈류검사가 가능했던 59명의 환자를 대상으로 내원 24시간 내에 ATL HDI-3000을 이용한 도플러 심초음파 검사를 시행하고 정상군(Normal:E/A>1, S/D>1,DT>140 ms), 이완기 장애군(Impaired relaxation:E/A<1, DT>140 ms), 가정상 혹은 제한성 장애군(Pseudonormal or Restrictive:E/A>1.5, S/D<1, with or without DT≤140 ms)으로 분류하였다. 각 군의 간헐파형 도플러 심초음파상의 지표들과 Color Mmode 도플러 심초음파상의 ROP(rate of propagation)값과의 관계를 알아보았다. 결 과: 간헐파형 도플러 심초음파 검사상 정상군은 22명,이완기 장애군은 34명, 가정상 혹은 제한성 장애군은 3명이었다. Color M-mode도플러 심초음파도를 이용한 ROP의 측정에서는 front wave method로는 50례 (84.7%)에서 측정이 가능하였으나 baseline shift method는 19례(32.3%)에서만 측정이 가능하였다. Front wave method로 측정한 ROP의 값도 정상군과 이완기 장애군 간에 통계적으로 유의한 차이를 보이지 않았다. 결 론: 대부분의 환자에서 front wave method를 이용한 ROP의 측정은 가능하였으나 급성 관동맥 증후군 환자의 좌심실 이완기능을 반영하는 단독지표로는 적합하지 않을 것으로 생각되며 baseline shift method를 이용한 ROP의 측정은 급성 관동맥 증후군 환자에서 유용하지 못한 것으로 생각된다.

장소 취약도에 대한 경관지표로서의 인간의 대응

한주엽 ( Joo Yup Han ),이민부 ( Min Boo Lee ) 한국지형학회 2012 한국지형학회지 Vol.19 No.1

제방 건설과 같은 인간 반응은 홍수와 같은 지형재해로 인해 발생하는 장소의 취약성에 대한 일종의 공간적 표현이다. 인간 반응은 장소의 취약성을 줄이기 위한 모든 인간 활동이 포함되며 이러한 인간의 반응은 지형재해 감소보다는 취약도 감소와 더 관련된다. 환경 인지에 대한 인간의 다양한 반응에 따라 장소의 취약도도 변화한다. 인간은 경험적인 위험 인지를 통하여 다양한 반응을 하고 이 반응은 공간에 반영된다. 인간 반응을 통하여 장소의 취약도를 예측하고 모형화하는데 있어 계량화가 가능하다. 지형재해에 대한 역동적 취약도 모형구축을 위해서는 지역의 지형형성작용에 대한 기초조사와 함께 인간의 반응에 대한 지도화가 요구된다. Human responses, such as construction of levees, are a spatial representation of the place vulnerability which is induced by a geomorphic hazard like flooding. Human responses include all forms of human activities to reduce the place vulnerability and they seem to be related with reducing vulnerability rather than reducing geomorphic hazards. Diverse human responses to the perceived environment bring about changes in the place vulnerability. People respond spatially to their vulnerability of the place in diverse ways from their experience and perceived risk. Human responses have quantitative possibilities in predicting and modeling the place vulnerability. Building the model of a dynamic place vulnerability to the diverse geomorphic hazards requires basic maps of geomorphic processes and human responses in the region.

이민부,한주엽,장의선 한국지리환경교육학회 2002 한국지리환경교육학회지 Vol.10 No.1

대도시 내의 생활지역과 같은 여러 소지역의 자연 및 인공환경을 이해하는 작업은 각 생활지역별 또는 도시 전체범위로 발생하는 환경문제에 대한 올바른 개념형성과 의사결정을 위하여 반드시 이루어져야 한다. 선행 문헌연구와 경관분석은 지역 환경교육 내용을 구성하고, 그의 교수-학습을 위한 주요 접근법이다. 또한 생활지역과 인근지역의 환경요소들은 효과적인 환경교육의 학습자료 및 내용으로 구성 될 수 있다. 현재의 있는 그대로의 지역 환경경관을 관찰하는 것이 도시의 환경교육 내용을 구성하는 데에서 중요하다. 지역 환경교육의 내용과 조사범위 지정, 주요 환경지표를 위한 교수활동은 조사지역에 대한 선행연구 분석, 경관분석에서 교사의 역할이 매우 큰 비중을 차지한다는 것을 뜻한다. 부산광역시의 좌천동·수정동·초량동 일대에 대한 환경학습 사례에서는 교사의 연구에 의한 학습자료의 구성과 제시가 학습자활동을 효과적으로 활성화시킬 수 있다는 관점 하에 구성하였다. 이러한 사례는 어느 특정 지역의 교사가 지역 간 교사들의 모임이나 학술활동을 통하여 다른 지역의 환경 정보를 얻으며 풍부한 환경교육의 자료로 이용할 수 있는 발판이 된다. Understanding of the natural and artificial environments of the living areas in the metropolitan region must be worked out for the right conception-building and decision-making about the environmental issues in their local living area together with the city as a whole. Bibliographical regional studies and landscape analyses are important in constructing and learning contents of the regional and environmental education. The environmental elements of living area and its neighboring area can be fieldsurveyed a nd mapped for the learning materials. The present environmental state of the region’s landscape is important in the construction of the city’s environmental contents. The study of previous works and landscape analysis on the study area are rather the teacher’s job for setting up the range and content of the regional environmental education and presenting major environmental indices to the student. As in a case of Jowacheon, Sujeong and Choryang-dong of Busan metropolitan city, just field work on the natural and artificial landscapes reveals many regional and environmental phenomena. For approaches to more materials of case studies, the teacher in local school has to collect other regions’ environmental informations through meetings for local teachers and academic activities.

1. This paper suggests one educational model of National Parks. The model includes main themes such as (1) concepts, (2) waste types, and (3) conservation policies of National Parks for the application at the school environmental education classes. 2. The study describes the origin of the national park system and concepts or policies for the conservation of the parks with cases of Japan, Taiwan, Canada, Australia, Swiss, Russia, and International Union for the Conservation of Nature and Natural Resources(IUCN). The main focuses of their concepts or policies are on the (1) public land, (2) conserved, (3) legally protected land, and (4) land for the education of the loving their country. 3. This research classifies wastes of parks as point, linear, areal, and cubic types, and explains wasting actions on each types, focused mainly on the mountainous national parks. 4. The suggested policies for the conserving national parks, in this paper, are (1) core-zoning policy, and (2) management policy within the core zone. 5. Some principles are suggested for the more effective realization of the policies: (1) enforcement, (2) abandonment,(3) restoration, (4) enlargement, (5) limitation, (6) incorporation, (7) monitoring, and (8) education. 6. Finally, the educational values of this model may be derived from concepts of (1) loving national land, (2) conservation of nature, (3) public responsibility for protection, and (4) education materials. Those concepts form the foundation of models for (1) civic education, (2) education of country, and (3) inquiry training.

The study aims to analyze environmental changes of the rural region neighboring against large city and rural residents' perception and attitude to the local environmental problems in their village. The study area is the small agricultural village, of which the geographical boundary is mountain divide and administrative unit is Ri. The study focus on the local environmetal change due to the urbanization and suburbanization of neighboring province capital city and the agricultural villagers' perception and atitude to the environmental change and environmental problems due to regional development. The research methods include review of previous theoretical and survey studies, landscape analysis with field survey, questionnaire surveys and statictical works. There are many factors of rural landscape changes, such as (1)urban pressure by urbanization and population growth, (2)industrial allocation, and (3)local autonomy. But according to the regional characteristics of villages, some particular factors influence more strongly on environmental changes than others do. In case of Duckchon Village these factors of the research are perceptional landscape and regional development. Research could identified environmental problems by the method of landscape analysis within the Duckchon Village boundary. Two main perceptions of environmental problems are water pollution and stock farming as sources of water pollution in the village. Residents thought the pollution level was very high and they considered the source of pollution to be the stock farms in Duckchon. They did not think the pollution due to manufacturing plant neighboring with Duckchon was so severe. These villager's view shows that they are very sensitive to the problems within village landscape boundary and not so out of boundary. In respect of regional development, residents agreed to the development for the welfare of the village but refused to accept development in case of the pollution possbility of water pollution within the village landscape boundary. The perception of villagers to environmental problems was focused around the village landscape boundary. They think one of the great problems is water pollution from stock farming within village boundary.

산계령 일대의 분수계와 지형 경관 분석

This work concerns with the drainage patterns in the karst region and aims to establish the divide line between two tributaries where stream piracy and the limestone solution are now recognized as greatly active. The divide is delineated from (1) the analysis of lineament on the landform, (2) the analysis of rock bedding, jointing and fractures, and (3) the linear pattern analysis and mapping of karst geomorphic elements like dolines and cockpits in the field survey and from the previous studies. Both the overland flow and the ground water flow are connected as the drainage system of the karst region. Assuming the water flows on to the sea-level, the main divide of mountain system can be drawn from the geomorphic divide and the phreatic divide concepts. The drainage patterns of the ground water are reflective of the fractures and strata of the rocks and the structural arrangements. The linearly distributed geomorphic elements of the karst region like sinkholes, dolines, cockpits can be viewed as the linear drainage patterns of the ground water. In San-Gae-Ryung karst region of the mid of Tae-Baek mountain system in Korea, the main geomorphic divide line differs from the administrative boundary line which defines the boundaries of ecoregions of the slip-face intermontane region to the east and the high flat region to the west. The geomorphic divide of the San-Gae-Ryung region is actually located to the south of the administrative boundaries according to the divide by connecting the highest points of the mountain system. The ground water of the independent karst drainage is considered to flow northward into the tributary of Joo-Soo river toward the East Sea. The movement of the geomorphic divide will happen in the future because the headward erosion of the tributary of Im-Gae river, one of tributaries of Han river, acts primarily on the deeply weathered southern slope of the main divide line. But the solution or collapse events of limestones under the northern divide of the independent drainages may offset the drainage direction change of main ground water flow by the headward erosion on the southern divide line and will keep the divide of the San-Gae-Ryung region. More quantitative analyses of solution rates and headward erosion rates on the slopes are needed to estimate the development of the divide in the future.
