This study was conducted to compare protected areas of South and North Korea based on international conservation criteria and recommend new fundamental directions for nature conservation policy. International conservation criteria used by this research were the 1994 IUCN protected area categories, composed of 6 management categories. Despite a variety of types and names of protected areas created by different domestic legislations, South Korea was revealed to have only two types of protected areas, Category IV and V, indicating the significant lack of ecological diversity and representativeness in its protected area system. Shockingly, there are no national parks meeting IUCN criteria in South Korea. On the other hand, North Korea has three IUCN Categories of II, III, IV and thus more balanced and ecologically representative protected area network than South Korea. Especially, North Korea maintains 9 national parks to be officially recognized by IUCN and UN. However, both South and North Korea should make sincere effort to have new and well-designed protected area system including all IUCN Categories I -Ⅵ and particularly a minimum area in the stricter protected area categories.

Despite the steady effort of kitchen furniture industry, consumers' complains never seem to decrease. The common storage problem of the houses of different sizes(20 pyeong, 30 pyeong, and 40 pyeong) was the dificiency of storage area and inadequate shelf division. It implies that such dificiency in kitchens is not because of the size of storage area, but because of such a great diversity of kitchenware and lack of studies on these items. The purpose of this research is to provide the checklist of the variety and quantity of stored kitchenware in researched area and easily adopt it to the kitchen furniture design. Studied household in average hold 239 types and about 890 items. The size of residence did not effect the number much. The first step of making the checklist is to categorize items into 9 biggest categories considering the usage of items and in which step of the preparing food the item was used. Second step is to categorize the items into 31 smaller categories reflecting the shape of items, the storage style and the place of storage. Third step is to sort the items into smallest categories by the frequency of use, storage type, and additional capacity of an item. Even when items are sorted into the same higher level of categories, the frequency of use caused storage area to differ. Also, storage style of an item differed according to the storage area. Based on these factors, we listed items in detail and made the checklist.

This study is aimed at establishing the categories and items for ecological assessment and evaluation of the environmental friendliness of golf courses in the capital region of Korea. The categories and items for the assessment have been derived based on the existing literature and interviews with golf experts. This study covers 32 golf courses in the capital region of Korea that are available in terms of data and on-site surveys. In order to conduct a comprehensive assessment of the environmental friendliness of the golf courses, the assessment area was divided into 4 categories that include a total of 14 sub-categories. The 4 categories encompass 1) location, 2) topography, 3) vegetation, and 4) construction. As its sub-categories, the location category includes current land use and zoning in the National Land Use Management Law. Topography has 2 sub-categories in the damage ratio of existing topography, gradient, cut area, and slope height. The assessment of vegetation is largely based on site surveys in the categories of preservation of the existing vegetation, the use of natural resources and existing trees, the component ratio of native tree species, the multi-layered structure of vegetation, and the utilization of water purification plants. In the aspect of construction, afforestation on tile slopes and the utilization of existing surface soil were evaluated. The examination of comparative analysis among the 10 items as a ratio measure showed that the scores were low in the sub-categories of current land we, the use of existing trees, and the multi-layered structure of vegetation. However, the rating results were satisfactory in the 2 sub-categories including cut area, and the utilization of native tree species. Those proved to be contributing factors in the ecological health of the golf courses. According to correlation analysis of the 10 items to the overall ecological rating of each golf course, the sizes of the 32 golf courses were mainly affected by the damage ratio of existing topography, gradient, preservation of vegetation and slope height. This study has the initiative to conduct an ecological assessment of golf courses in the country based on site surveys. The study results revealed that location factors such as current land use, damage ratio of topography and gradient and topographical factors were the main factors affecting the environmental friendliness of golf courses. This indicates indicating the significance of these factors in the future construction practices of golf courses. Furthermore, this study raises the need for follow-up studies to establish more detailed assessment criteria and to develop assessment techniques for areas such as slope afforestation and water purification plants that need a qualitative approach.

연구는 서울시 도시대기 측정망의 월별 미세먼지 농도와 측정소 주변 버퍼별, 토지피복 유형별 비율의 관계를 분석하여 미세먼지 농도에 대한 토지피복의 영향을 규명하고자 하였다. 대분류 토지피복 유형과 미세먼지 농도의 월별 상관분석 결과 버퍼 3km에서, PM_2.5보다 PM₁₀에서 상관성이 잘 나타났고, 산림과 뚜렷한 음의 상관관계, 초지와 시가지는 PM₁₀과, 나지와 시가지는 PM_2.5와 일부 양의 상관관계를 나타냈다. 버퍼 3km 내 중분류 및 세분류 우세 피복유형의 월별 상관분석 결과 PM₁₀은 활엽수림과 뚜렷한 음의 상관관계를 나타냈고, 도로와 일부 양의 상관이 우세한 편이었다. PM_2.5는 활엽수림과 일부 음의 상관, 상업지역과 일부 양의 상관이 많은 편이었다. 그 밖에 초지 및 나지 세부 유형의 상관성은 매우 낮거나 없었다. 양의 상관 및 음의 상관관계의 각 대표 피복유형으로 단계선택법에 의한 월별 회귀분석을 실시한 결과 PM₁₀은 활엽수림 비율 증가에 의한 농도 감소 영향이 뚜렷하였고, 도로는 변수선택에서 제거되었다. PM_2.5는 일부 월별로 상업지역 비율 증가에 따른 농도 증가 영향 또는 활엽수림 비율 증가에 따른 농도 감소 영향을 받았지만, 그 영향력은 PM₁₀에 비해 낮았다. 연구결과 측정소 주변 토지피복은 미세먼지 농도 증감에 영향을 주었고, 그 영향은 PM₁₀에서 더 분명하였다. 산림 유형은 미세먼지 농도에 가장 크고, 분명한 영향을 주는 저감 요인이었다. 시가화지역 관련 유형들의 농도 증가 영향은 일부 확인되었다. 도심 산림의 미세먼지 저감 기능은 분명한 효과를 가진 것으로 보이며, 향후 녹지의 세부 특성과 복잡한 도시환경 요인의 작용을 규명하는 후속 연구가 필요하였다.

Objectives : The purpose of this study was to confirm that the pulse analyzer is useful for analyzing characteristics of variables of pulse waves in age categories, evaluating pulse waves of the metabolic syndrome group, compared with those of the non-metabolic syndrome group in Korean adults. Methods : The pulse wave variables were measured in Guan of all 1,056 subjects by the pulse analyzer, using a pen-type piezoresistive sensor. The physical measurement, blood test and survey were also performed by each subject. Results : In the age categories, height of pre-incisura (h2), height of tidal wave (h3), area of percussion wave (Aw), and width of percussion wave (w) increased in accordance with increase in age. While ratio of systolic period area (As) went up according to the increase of age, ratio of diastolic period area (Ad) went down. Radial augmentation index (R-AI), h2/h1, h3/h1, w/t and angle of percussion wave went up by aging, generally. Aw rate (Aw/At) also increased. Among the metabolic syndrome group, in the ages of 19 and 44, ratio of systolic period area (As) was higher and ratio of diastolic period area (Ad) was lower than in the non-metabolic group. w/t, Aw/At, and angle of percussion wave were higher than in the non-metabolic syndrome group. Among the metabolic syndrome group over the age of 60, height of pre-incisura (h2), height of tidal wave (h3), total area (At), area of percussion wave (Aw), radial augmentation index (R-AI), h2/h1 and h3/h1 were higher than in the non-metabolic syndrome group. Conclusions : The pulse analyzer is useful to analyze arterial stiffness in the age categories and in the metabolic syndrome group by some measures.

The relationship between urban spatial structures and GHG-AP integrated emissions was investigated by statistically analyzing those from 25 administrative districts of Seoul. Urban spatial structures, of which data were obtained from Seoul statistics yearbook, were classified into five categories of city development, residence, environment, traffic and economy. They were further classified into 10 components of local area, population, number of households, residential area, forest area, park area, registered vehicles, road area, number of businesses and total local taxes. GHG-AP integrated emissions were estimated based on IPCC(intergovernmental panel on climate change) 2006 guidelines, guideline for government greenhouse inventories, EPA AP-42(compilation of air pollutant emission factors) and preliminary studies. The result of statistical analysis indicated that GHG-AP integrated emissions were significantly correlated with urban spatial structures. The correlation analysis results showed that registered vehicles for GHG (r=0.803, p<0.01), forest area for AP (r=0.996, p<0.01), and park area for AP (r=0.889, p<0.01) were highly significant. From the factor analysis, three groups such as city and traffic categories, economy category and environment category were identified to be the governing factors controlling GHG-AP emissions. The multiple regression analysis also represented that the most influencing factors on GHG-AP emissions were categories of traffic and environment. 25 administrative districts of Seoul were clustered into six groups, of which each has similar characteristics of urban spatial structures and GHG-AP integrated emissions.
