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.
This study investigated the characteristics of architectural planning in the youth training centers, which were introduced to the magazines from 2000 to 2010. The result are as followings. Firstly, the youth training centers were located mainly in general residential area, that the youth could be easily accessible. And, it were located mainly in green natural area, which is adjacent to the mountain or park. The site area of the youth training center was analyzed to approximately $10,000m^2$ below. Secondly, the placement and the form of the youth training center is divided two types, which are a single and two buildings type. A single building case is found the type of 'ㄴ' and 'ㄷ' shape, and two buildings case is found the type of 'ㄴ + ㅡ', 'opened ㅁ', 'ㅡ + ㅡ' shape. It is found mostly the type of 'ㄷ' shape. Thirdly, the youth training center is planned mostly with fifth stories above ground and three underground levels. And, sometimes it is planned a mixed-use buildings with a sports center, community center and senior welfare center. Lastly, the space of youth training center is zoned horizontally for each mass of building, which is planned the educational, cultural and sports facilities. And, it is zoned vertically some of the sports facilities and administrative support facilities in the underground, and a educational and cultural facilities on the ground.

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.
This study was conducted to investigate the flora of Mt. Jang located at Haeundae-Gu in Busan. The survey for the flora was carried out from Oct. 2008 to Sep. 2009. The results were obtained as follows. The flora consists of 5 forms, 22 varieties, 238 species, 198 genera, 91 families, 47 orders, 7 classes, and 3 divisions as total 265 taxa. The typical communities were Osmunda japonica com., Stephanandra incisa com., Gleichenia japonica com., Eurya japonica-Pinus thunbergii com., Styrax japonica-Pinus thunbergii com., and Smilax china com. which were distributed along Forest Bathing Area and Yangun Falls, Miscanthus sinensis for. purpurascens com., Carpinus turczaibovii var. coreana com and Pseudosasa japonica were distributed around the top of mountain. According to the ecological characteristic species, the evergreen plants were observed 15 taxa 14 genera 13 families, the naturalized plants 18 taxa 17 genera 10 families, the specific plants categorized by Ministry of Environment 20 taxa 18 genera 18 families, the endangered plant 1 specie Utricularia yakusimensis, and the cultivated plants were observed 21 taxa 18 genera 14 families.
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.
Distribution types of native conifers (Juniperus chinensis, Pinus parviflora, Tusga sieboldii and Taxus cuspidata var. latifolia) were studied by phytosociological investigation and ZM method in Ulleung Island, South Korea. Two main types were divided maritime vegetation (Juniperus chinensis forest) and mountain vegetation (Taxus cuspidata var. latifolia forest and Pinus parviflora-Tusga sieboldii forest). The former was divided into sea cliff distribution (J-SC) and sea ridge distribution (J-SR) type. The latter was classified 7 distribution types; Taxus cuspidata var. latifolia forest was rock distribution (Ta-R) and mountain slope distribution (Ta-MS) type, and Pinus parviflora-Tusga sieboldii forest was rock distribution (P T-R), upper and ridge distribution (P T-UR, 3 units sub-types:1sub, 2sub, 3sub), and Mountain slope distribution (P T-MS) type. It was considered that J-SC, Ta- R, and P T-R were maintained by topographic climax, but J-SR, Ta-MS, P T-UR and P T-MS were the process of vegetation succession. Distribution types of topographic climax are entrusted to process of vegetation succession. Types in the process of vegetation succession will be needed tending of forest to promote saplings growth and seedlings germination. Especially in order to restore Tsuga sieboldii forest should be afforest and make forest gap because It is mid shade tolerant tree and purity percentage of its seed is 1~2%. It was considered that the composition of group mixture forest constituted Pinus parviflora, Tsuga sieboldii, Taxus cuspidata, Camellia japonica, Machilus thunbergii and Acer okamotoanum, etc. will be able to restore native vegetation, after take the form of forest gap by strong thinning and pruning of Pinus thunbergii forest.

This Study is about the "Comprehensive Landscape Improvement Plan for Gu-ryoung Seaside Village that was one of most exhibited projects for developing sea villages." The formulations of the plan were supervised by the Ministry of Land, Transport, and Maritime Affairs and were executed by the Goheung Country. Rather than proposing renovations for the landscape, this study maintains the existing order and attempts to examine the plan by scrutinizing the vernacular design language of the landscape. In the study, community members had the opportunity to express their opinions and ideas about the community through workshops composed of community participation programs, and participated in the decision-making process through consultation meetings. The conclusion of this study was relevant to the activities of the committee on landscape improvement. The Comprehensive Landscape Improvement Plan has three objectives: (1) resorting and modifying the natural landscape, (2) restructuring the roadways, and (3) modifying key spaces. In the end, the role of Gu-ryong Mountain as a background of the landscape was focused on tree planting drives that were undertaken, and accessibility to the sea front was improved. Second, in restructuring the roadways, rough roads were restored and unconnected roads were connected to ensure a network of roads along the sea front, inner roads in the village, roads at the Fringes Mountains, and stone roads on the mud flat. In addition, roads were named according to the character of the landscape and signs were installed. Finally, the existing key spaces, in which community members came together, were restored and new key spaces were created for the outdoor activities of the inhabitants and the diverse experience of visitors. A guideline was also created to regulate private areas such as roofs, walls, fences of residential buildings, and private container boxes and fishing gear along the sea front. The strength of this study is that it is seeking to determine the greatest potential of the landscape and set the plan by examining the lives of community members. Some problems were found during the development of this study. Further, there were problems in the community's understanding as elaborated below. First is the gap between community members' awareness and practice. Even though they were aware of the problems with the village landscape, they hesitated to implement improvements. Second, community members have misunderstandings about the landscape the improvement plan. The local government and the residents have understood this plan as a development project; for example, new building construction or the extension of roads. Third, residents are not aware that continuous attention and improvements are required for the upkeep of the landscape in the sea village. The plan to improve the landscape should promote a balance between making the area as a tourist attraction and maintaining the lives and cultural activities, because the sea village system incorporates settlements, economy, and culture.
