  • Gastric cancer (GC) is the fifth most common cancer in the world, with a wide variation in incidence rates across different geographical areas. In Iran GC is the most common cancer in males and it is reported to be the third most prevalent after breast and colorectal in females. A geographical information system (GIS) allows investigation of the geographical distribution of diseases. The purpose of the present study was to explore the relationship between gastric cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. Of all cases, 672 (73.8%) were in males with a sex ratio of 3 to1. The highest incidence by cities was seen in Namin with 137.5 per 100,000. The results of this study showed that the distribution of GC around the Sabalan volcanic mountain was significantly higher than other places in the same province. These results can be considered as a window to future comprehensive research on gastric cancer.

  • The purpose of this study is to investigate the location characteristics of the rice paddy fields and to predict shrinking areas of them. The study area is in South Korea nationwide, and a 300×300m raster level is adopted as a spatial analysis unit. The binary logit model and spatial simulation model are employed for the analyses. As a result, population, industry, climate and nature, and accessibility play a significant role in determining rice paddy fields' locations. It is predicted that the shrinking rate will be high in Gangwon-do, Gyeongsangbuk-do, and Gyeongsangnam-do until 2027. The hot spots are intensively shaped in the inland of Gangwon-do, eastern parts of Gyeonggi-do, and the borders of Gyeongsangnam-do and Jeollabuk-do between Charyeong and Sobaek mountain ranges. Using Gimcheon-si as an example, the study suggests fundamental policy implications for taking advantage of the simulation results from the lens of local agriculture. Several policy measures are proposed for improving management strategies for the rice paddy fields in the long run.

  • The purpose of this study is to offer basic data of education to improve farm lives though investigating rural homemakers' life style. The results of this study are as follows : 1. The life structure of rural homemakers was classified into two structures as a material resources and human resources. The life style of rural homemakers was classified into systematical life style, traditional value style, social active style, and progressive active style. 2. The life styles of rural homemakers according to social population variance were as follows. The lower of age, homemakers whose family incomes more 30 million won or below 10 million won, who has religions, who employed in livestock were showed at very systematical life style. The homemakers who live in mountain village, higher the much age becomes, and the education level become lower, have showed traditional value style. Rural homemakers the lower of age, the higher incomes, composed of single parent + children who remain single were appeared social active style. Rural homemakers the lower of age, the more shortened farm life periods, who employed in livestock were appeared progressive active style. 3. Systematical life style was more affected by material resources structure, traditional value style was affected by material resources. And social active style was more affected by human resources, progressive active style was affected by human resources.

  • This paper contains the results obtained by ecological investigation of ilora in Muie Island of Incheon Harbor in the xestern coast in Korea. 14 varieties, 1-27 species, 57 families and 142 genera of Tracheophyta were recorded by field investigations conducted over three times in May and July, 1976 and August, 1980. The flora of this island showed a plant community predominated by Pinus densiflol-a grown in miggle with Carpinus laxiflora, Quel-cus serrata and Rhododendron muucronulatum. Generally, the number of plant species was scarce, but it was an unexpected result that such remote mountainous plants as Lysinzachia clethrozdes, Sy7zeilesis palnzata and Lilzunz disttcum etc. were encountered in a wood surrounding Seohwang-dang, the shrine of a tutelary deity, on 126-Meter Hill at the northern end of the island. There also countered in Hoyong mountain valley were deciduous broad-leaved forests without pine tree which mainly consisted of Prunus leveillea7za, Fraxinus rhynchophylla, Platycarya strofilada, Quercus serrata. Quercus acutissznza and Acer mono. In addition, herbaceous plants, such as Syneilesis palmata, Codonopsis lanceolata and Lysi\ulcornerna barystnchy were grown as the undergrowth of these forests. Drosera rotundifolio, an unlooked-for plant, . appeared in the middle of the eastern coast of the island. Camellia japo7tica was grown spontaneously in Deogjeog Island 261cm southwest from the island, while no evergreen broa-leaved tree could be located except 2 species of Vztex rotztndifolia and Euo~zymus japonrca. It may be considered that such simple flora of this island compared with that of land is attributed to the fact that the formation of the former took place in the period far latter than that of the latter.

  • This study analyzed the impact of greenhouse cultivation area and groundwater level changes due to the water curtain cultivation in the greenhouse complexes. The groundwater observation data in the Miryang study area were used and classified into greenhouse and field cultivation areas to compare the groundwater impact of water curtain cultivation in the greenhouse complex. We identified the characteristics of the groundwater time series data by the terrain of the study area and selected the optimal model through time series analysis. We analyzed the time series data for each terrain's two representative groundwater observation wells. The Seasonal ARIMA model was chosen as the optimal model for riverside well, and for plain and mountain well, the ARIMA model and Seasonal ARIMA model were selected as the optimal model. A suitable prediction model is not limited to one model due to a change in a groundwater level fluctuation pattern caused by a surrounding environment change but may change over time. Therefore, it is necessary to periodically check and revise the optimal model rather than continuously applying one selected ARIMA model. Groundwater forecasting results through time series analysis can be used for sustainable groundwater resource management.

  • Background: Parthenium hysterophorus L. (Asteraceae; hereafter Parthenium) is an invasive alien species of global significance because of its' negative ecological and socioeconomic impacts. This species is spreading rapidly from lowland Tarai to Middle Mountain regions in Nepal. In the present study, we analyzed the impacts of Parthenium on plant community composition including their soil seedbank in subtropical grasslands located in central Nepal. Data was collected in a 10 m long transects passing through areas of high (> 90% cover), medium (40%-60%) and low (< 10%) levels of Parthenium cover using a plot of 1 m2. Altogether, we sampled 90 plots in 30 transects. Seedling emergence method was used to estimate soil seedbank density in the soil samples (0-10 cm depth) collected from the plots with high Parthenium cover. Results: There was no significant difference in the plant species richness at different levels of Parthenium invasion whereas there was a significant change in the species composition of above ground flora due to Parthenium invasion. There was also a significant difference in species composition between soil seedbank and aboveground flora in the highly invaded plots. Parthenium was the most dominant in soil seedbank, contributing 65% to the total soil seedbank. Conclusions: Our study suggests that Parthenium has considerable negative impact on the native grassland flora, and the dominance of Parthenium in the soil seedbank means there is a challenge for its management. It also suggests the need of monitoring the soil seedbank dynamics while managing Parthenium weed.

  • 본 연구는 '2010년도 해안마을 경관형성 시범사업'의 일환으로 국토해양부가 주관하고 고흥군이 시행한 '구룡 해안마을 경관형성 기본계획'을 다룬다. 해안마을 경관은 정주, 경제, 문화 활동을 포함하고 있는 시스템이므로 해안마을 경관형성 기본계획은 관광자원화와 정주환경조성, 문화 활동 간의 균형이 필요하다고 보았다. 이에 '주민들의 생활이 이루어지고 있는 경관의 잠재성과 생활문화방식을 존중하면서 경관의 개선 및 증진'을 주요 목적으로 설정했다. 연구 진행에 있어서는 주민참여 프로그램을 운영해 주민들 스스로가 자신들의 경관 인식과 아이디어를 이야기할 수 있도록 했고 경관 추진위원회라는 소통 창구를 통해 경관형성 계획과 관련된 의사결정을 진행했다. 경관형성 계획은 먼저 시간에 따라 훼손된 자연경관을 복원하고 정비하였다. 구룡산은 배후산으로서 역할을 할 수 있도록 나대지를 복원하고 산마루 지형을 활용하여 전망공간을 조성했다. 해안과 관련해서는 돌을 사용한 계단식 스탠드와 노두길 조성으로 접근성을 높였다. 마을 길 체계는 해안도로, 마을 안길, 산자락길, 노두길 등을 대상으로 사라진 길은 복원하고, 끊긴 부분은 잇고 연결하면서 경관 주제에 맞도록 재구성하였다. 또한 주민들의 외부활동 편의성 증진과 방문객이 체계적인 경험을 할 수 있도록 기존의 거점 공간을 정비하거나 새롭게 조성했다. 이와 함께 가이드라인을 통해 사적영역에서의 경관 개선이 이루어지도록 했다. 가이드라인은 건축물의 지붕 벽체 담장과 가로에 놓이는 컨테이너 박스와 어구를 대상으로 했다. 본 연구는 주민참여 프로그램과 주민들과의 협의를 통해 주민들의 생활에 밀착한 해안마을 경관형성 기본계획을 수립했다는데 의의가 있다. 연구를 진행하면서 해안마을 경관 형성 사업의 한계점과 과제도 발견할 수 있었는데, 첫째는 주민들의 인식과 실천 사이의 간극이다. 주민들은 마을경관의 문제점을 알고 있었으나 실제 행동으로 옮기는데 있어서는 한계를 나타냈다. 둘째는 마을 경관형성사업에 대한 이해와 인식의 부족이다. 지방정부와 주민들은 마을 경관형성 사업을 신규 건축이나 도로 확장 같은 개발 사업으로 이해하는 경향이 있었다. 셋째는 경관이 그러하듯이, 이러한 계획은 단시간에 이루어지지 않으므로 일회적인 사업보다는 지속적인 관심과 지원이 필요하다는 것이다.
