  • Recently, by fast industralization and development without environmental concern, our environment deterioration have being continued rapidly. Therefore, many species is placed on crisis of extinction or was already extincted by habitat destruction. In Minjujisan area, there is a plan to construct the Sport and Leisure Complex by which convert the forest conservancy district to the district of development promotion and district of sighseeing and leisure by Yongdong District. To investigate the avifauna impacts by habitat destruction, bird censuses was carried out before the Sport and Leisure Complex be construct in Minjujisan and Sokgisan area during 4-5 May, 1992 and 16-21 June, 1992. Total 229 birds of 41 species in 23 family of 9 orders were recorded during censuses. Sitta europaea amurensis was the most abundant species and Parus ater amurensis, Phylloscopus borealis xanthodryas, Parus major wladiwostokensis, Parus palustris hellmayri, and Turdus pallidus were dominant species. Accipiter nisus nisosimilis, Accipiter soloenis, and Otus scops stictonotus were found out to the natural monuments in this suvey. Halcyon pileate was observed to a rare bird in this surveyed area. Species diversity of this census was 3.381 which showed slightly higher degree than other surveyed area. The area of Minjujisan, Sokgipong, and Samdopong which have little pollution agent around there and kept away from mankind were approved the heavy avifauna area which have so many bird species. Biogeographically, the Taebaek Mountains was connected with the Sobaek Mountains through this area, therefore it was significant that many animal species could be move to each mountains ranges. The construction plan of the Sport and Leisure Complex in Minjujisan area should be restrain with concern about environmentally destruction by the Muju Resort in Dokyusan National Park which connected to that area have master plan to development the ski slopes for the 1997 Universiad with permission by the Ministry of Environment.

  • For a few people's leisure, the natural environment have being deteriorated ceaseless. The plan of the Chungchongpuk Province and the Yungdong District in Chungchongpuk-do which drive foreword the sport and leasure complex designed to construct ski slopes, golf course, and resort hotel in 6,000,000 $m^2$ of natural ecosystem around the Mulhan Valley at Mulhan-ri Sangchon-myon Yungdong-kun Chung-chcngbuk-do by Dongsin Leisure have concerned decrease on biological diversity serious. This study carried out by census Amphibia and Reptilia fauna in the Mulhan Valley to expect the impact of animal diversity by construction of leasure complex and to call attention to understand that impact. 8 species in 5 Families of 2 Orders in Amphibia and 5 species in 2 Families of 1 Order in Reptilia were observed in the Mulhan Valley during June 24, 1994 to June 25, 1994 which showed to be similar to the Natural Park in Korea. 4 of 8 species in Amphibia(Hynobius leechii, Onychodactylus fischeri, Bufo bufo gargarizans, and Rana dybowskii) and 3 of 5 species in Reptilia(Eluphe rufodorsata, Dinodon rufodonatum rufodonatum, and Agkistrodon saxatilus) were revealed the Special Wild Animal recorded by the Ministry of Environment in 1993. Therefore, the Minjujisan seems to have highly reason to conservation by these animal diversity. Around the Minjujisan province was significant connecting the Taebaek Mountains and the Sobaek Mountains on biogeographically with Dokyusan National Park. The plan of Leasure complex in the Mulhan Valley should be cancel in consideration of destruction around the Dokyusan National Park severely by the Muju Resort, Ski slopes, etc. The Minjujisan must be conserve to the Zone of Natural Environment on Amphibia and Reptilia diversity and animal migration route.

  • To see the influence of bird species by the change of temperature in city, we have carried out bird census 22 times for 6 years from 2003 to 2008 in Worldcup Park, Seoul. And we analysed the correlation between the temperature of Seoul and wildbirds. 15 orders, 38 families and 102 species were confirmed to have existed. We could find that Hypsipetes amaurotis gradually turned out to have increased with statistical significance for 6 years. To analyze the relationship between the temperature of Seoul and wildbirds, we have chosen 31 bird species observed more than 30% in frequency and proceeded the regression analysis. The survey shows that with the temperature rise the number of the resident birds such as Pica pica, Parus palustris, Anas platyrhynchos and Anas poecilorhyncha and the migratory birds such as Buteo buteo has declined. These 5 species have a possibility to be decreased as a global climate warming and maybe move to another habitat. In contrast, Oriolus chinensis and Falco tinnunculus are characterized into the species that increased due to the rising temperature. So they have a posibility to increase and expand their habitat. This survey shows that temperature rise can cause to change the composition of bird species. And 7 bird species related with the change of temperature have a great possibility as a indicator of the climate change.

  • Objectives: The aim of this study was to characterize the community health indicators affecting standardized mortality rate of cerebrovascular diseases(CVD) and to identify the relationship between CVD mortality and community health indicators in Gangwon-do. Methods: The community health indicators included material deprivation index, medical resource, rates of road pavement and local tax. CVD mortality and the material deprivation index were calculated in the registered death data and the 2000 census which were obtained from the Korean National Statistics Office. The community health indicators were measured using 2001 statistical year book of Ganwon-do. Data were analyzed by using Excel 2003, SAS 9.1. CVD mortality and material deprivation index were visualized by Arcview 9.1. Results: CVD mortality varied by region and sex in Gangwon-do. The highest CVD mortality in male and female were noted at Goseong-gun, the lowest CVD mortality in male was at Yangyang-gun as it of female at Pyeongchang-gun. In Taebaek city where material deprivation index was also the highest; in Pyeongchang-gun was the lowest. Also the higher material deprivation index in some regions was the higher CVD mortality was. CVD mortality was not related with community health indicators. Conclusions: The results showed the regional difference of mortality of CVD among counties and cities in Gangwon-do. It is recommended that other community health indicators besides material deprivation index, road pavement rate, medical resources and local tax affecting CVD mortality need to be considered to improve the preventive strategies.

  • Minimum Housing Standard is an instrument to cope with the problems of public health and community hygiene, deterioration of working class housing conditions appeared commonly in the process of capitalist industrialization and rapid rural-to-urban migration. This paper aims to examine the institutionalization of histories of minimum housing standard in the advanced countries, and analyze the spatio-temporal changes and characteristics of households failing to meet the New Minimum Housing Standard in Seoul Metropolitan since 1995. The analysis of this paper is based on the census data on population and housing. The results are as follows; Households failing to meet the New Minimum Housing Standard in Seoul are 501,000 households(1.368 million person, 14.4%). This means Seoul has overtaken the national average 11.8% for the first time and there are structurally marginal band of households who can not improve the housing conditions by themselves. In addition, the fact that the rate of Seoul households living in the marginal shelter including the basement and rooftop room is the highest in Korea means the housing quality issues of Seoul is serious. Spatial distribution of households failing to meet the standard is divided into the northeast area and the southwest area in Seoul. Main features of the households are female-headed families, middle and old-aged people, divorce families, lower educated people, under and graduate students, non-apartments, dweller in 15~20 year old houses.

  • This paper aims at examining the regional comparison of the business organization of retailing in the Seoul and Taegu metropolitan areas, as an attempt to understand regional structure of retailing within metropolitan areas which represents the suburbanization. On the national level, retail sales have concentrated on larger metropolitan area, the Seoul metroplitan area, the first largest metropolitan area, having higher sales for population scale. While the Taegu metropolitan area, the third largest metropolitan area, appears to lower retail sales for population scale. In order to confirm such phenomenon, this paper is to analyze and to compare the industrial composition of retailing by industry in 1991 of Seoul with that of Taegu. And this paper is to analyze the regional comparison of business organization of retailing: the percents of establishments under four employees, of juridical establishments, of employees of ordinary times, the annual sales per establishment of retailing. And the characteristics of business organization of retailing by industry are analyzed by principal components analysis, and the explanation of the types with component in each district(city, county, ward) is analyzed by cluster analysis(Ward method). The data of 1991 were obtained from the statistics in the Report on Establishment Census(Vol.3 Wholesale and Retail Trade) published by the National Statistics Office. The results are as follows: 1. The composition of retailing by industry in Seoul metropolitan area by annual sales in 1991 is characterized as appeared very higher composition rates of retailing of textiles, clothing, footwear and apparel accessaries', ‘retailing of furniture, home furnishings and equipment’, retailing of jewellery and watches’, ‘retailing of printed matter and stationery’, ‘retailing of personal transport equipment and gasoline service stations’, and ‘general merchandise stores’. But in Taegu metropolitan area, ‘retailing of food, beverages and tobacco’, ‘retailing of drugs, cosmetics and other chemical goods’, 'retailing household fuel’, and ‘genernal retail trade, n.e.c.’appears very high. Therefore Seoul metropolitan area has larger business scale and retailing of shopping goods has developed than Taegu metropolitan area.

  • Background: Breast cancer is the most common cancer in women worldwide with a rising incidence rate in most countries. Considering the increase in life expectancy and change in lifestyle of Iranian women, this study investigated the age-adjusted trend of breast cancer incidence during 2000-2009 and predicted its incidence to 2020. Materials and Methods: The 1997 and 2006 census results were used for the projection of female population by age through the cohort-component method over the studied years. Data from the Iranian cancer registration system were used to calculate the annual incidence rate of breast cancer. The age-adjusted incidence rate was then calculated using the WHO standard population distribution. The five-year-age-specific incidence rates were also obtained for each year and future incidence was determined using the trend analysis method. Annual percentage change (APC) was calculated through the joinpoint regression method. Results: The bias adjusted incidence rate of breast cancer increased from 16.7 per 100,000 women in 2000 to 33.6 per 100,000 women in 2009. The incidence of breast cancer had a growing trend in almost all age groups above 30 years over the studied years. In this period, the age groups of 45-65 years had the highest incidence. Investigation into the joinpoint curve showed that the curve had a steep slope with an APC of 23.4% before the first joinpoint, but became milder after this. From 2005 to 2009, the APC was calculated as 2.7%, through which the incidence of breast cancer in 2020 was predicted as 63.0 per 100,000 women. Conclusions: The age-adjusted incidence rate of breast cancer continues to increas in Iranian women. It is predicted that this trend will continue until 2020. Therefore, it seems necessary to prioritize the prevention, control and care for breast cancer in Iran.

  • The present study is to investigate the characteristics and determinants of spatial distribution of strong small farm by defining the term, strong small farm (SSF) extracting the SSF households data dealing with apples, from 2010 Census of Agriculture, Forestry and Fisheries, Korea. Spatial distribution and concentration of SSF are analyzed based on spatial clustering techniques. We construct discrete dependent variables on strong and non-strong small farms and then analyze the determinants of the SSFs using probit model, with independent variables including population and economic characteristics and management characteristics. As of 2010, the apple SSFs, 1,529 households in total, are geographically concentrated in Gyeonsangbuk-do according to the analysis results. The determinants of SSF are similar to those of farms' earnings. When located in the apple producing area, and participating in producers organization while selling products directly, the farm is highly likely an SSF. The findings and results of the present study are expected to provide fundamental information helpful for preparing and implementing policies for SSFs in that the present study investigates the characteristics of SSF, which is a prerequisite step for SSF-related policies.

  • To evaluate the parasitic infection rates among inhabitants in urban area of Seoul, Korea, a total of 5,275 stool and anal swab specimens was obtained from 2,527 male and Z,748 female living in 24 Dongs of 17 Kus. Cases were sampled randomely to represent 1,000 inhabitants refereed to the census in 1980. The methods employed were formalin ether technique to detect helminth ova and protozoan cysts and scotch tape anal swab technique to detect eggs of Enterobius vermicularis. The results obtained are as follows ; 1) Total positive rate of helminthes was 23.5% among 5,275 (male 22.5% and female 24.5%) specimens. Nine kinds of the helminthes were detected and infection rates of each helminth were; Ascaris lumbricoides 4.1%, Hookworm 0.1%, Trichuris trichiura 11.1%, Trichostrongylus orientalis 0.1%. Clonorchis sinensis 1.2%, Metagonimus yokogawai 0.1%, Taenia spp. 0.2%, Hymenolepis nana 0.3 and Enterobius vermicularis 9.6%. 2) Total positive rate of intestinal protozoa was 1.4%. Four kinds of the protozoan cysts were detected and the infection rates of each protozoa were; Entamoeba histolytica 0.15%, E. coli 0.4%, Endolimax nana 0.04% and Giardia lamblia 0.89%. 3) No significant differences in the parasitic infection rate by sex was noticed although male group showed lower infection rate than female group. However the incidence of C. sinensis, M. yokogawai and Taenia spp. was twice as much in female group as in male group. 4) No difference in the infection rate by age was found although E. vermicularis positive rate was highest in "0~9 years group" by 2.1% and C. sinensis infection rate was higher in over "30~39 years group". The parasitic infection rate of the present study was significantly lower than those of previous reports in Seoul area and other provinces.

  • This paper proposes a method of boosting-based classification for the purpose of real-time face detection. The proposed method uses depth images to ensure strong performance of face detection in response to changes in lighting and face size, and uses the depth difference feature to conduct learning and recognition through the I-MCTBoost classifier. I-MCTBoost performs recognition by connecting the strong classifiers that are constituted from weak classifiers. The learning process for the weak classifiers is as follows: first, depth difference features are generated, and eight of these features are combined to form the weak classifier, and each feature is expressed as a binary bit. Strong classifiers undergo learning through the process of repeatedly selecting a specified number of weak classifiers, and become capable of strong classification through a learning process in which the weight of the learning samples are renewed and learning data is added. This paper explains depth difference features and proposes a learning method for the weak classifiers and strong classifiers of I-MCTBoost. Lastly, the paper presents comparisons of the proposed classifiers and the classifiers using conventional MCT through qualitative and quantitative analyses to establish the feasibility and efficiency of the proposed classifiers.
