본 연구는 농협 농산물 물류센터의 상적, 물적 유통체계를 파악하고, 물류의 효율성과 집약화를 위해 설립된 청주 물류센터의 계절별 농$.$축$.$수산물의 입하지를 고찰하고자 한다. 그리고 각 상품의 판매액에 의한 배송의 지역유형과 지역특성과의 관계를 밝히는 것을 연구목적으로 한다. 그 결과 청주 물류센터는 충북을 핵심지역으로 전국에서 농$.$축$.$수산물을 입하하여 충북과 충남, 대전시 일부 지역에 배송을 집중화시키고 있다. 이는 청주 물류센터가 취급하고 있는 농$.$축$.$수산물이 신선도를 요하는 상품이기 때문에 물류센터에서 상대적으로 가까운 지역에서 주로 입하하여 근거리 배송을 하는 지역 물류시스템을 형성하고 있다는 것이다. 이러한 농$.$축$.$수산물의 배송은 수급관계라는 경제원칙뿐만 아니라 물류센터의 판매전략도 크게 작용하고 있다.

This paper aims at an investigation of the features of bacterial communities in surface sediments of the South China Sea (SCS). In particular, biogeographical distribution patterns and the phylogenetic diversity of bacteria found in sediments collected from a coral reef platform, a continental slope, and a deep-sea basin were determined. Bacterial diversity was measured by an observation of 16S rRNA genes, and 18 phylogenetic groups were identified in the bacterial clone library. Planctomycetes, Deltaproteobacteria, candidate division OP11, and Alphaproteobacteria made up the majority of the bacteria in the samples, with their mean bacterial clones being 16%, 15%, 12%, and 9%, respectively. By comparison, the bacterial communities found in the SCS surface sediments were significantly different from other previously observed deep-sea bacterial communities. This research also emphasizes the fact that geographical factors have an impact on the biogeographical distribution patterns of bacterial communities. For instance, canonical correspondence analyses illustrated that the percentage of sand weight and water depth are important factors affecting the bacterial community composition. Therefore, this study highlights the importance of adequately determining the relationship between geographical factors and the distribution of bacteria in the world's seas and oceans.

We examined the evolutionary and ecological processes shaping current geographical distributions of a Korean wood-eating cockroach species, Cryptocercus kyebangensis. Our research aims were to understand evolutionary pattern of DNA sequences, to construct genetic network of Cryptocercus kyebangensis local populations and to understand evolutionary and ecological processes shaping their current geographical distribution patterns via DNA sequence information and genetic networks, using sequence data of two genes (ITS-2 and AT region) from local populations of C. kyebangensis. The results suggest that the ITS-2 and AT region are appropriate molecular markers for elucidating C. kyebangensis geographic patterns at the population level. The MSN-A based on the ITS-2 showed two possible routes, the Hwaak-san and Myeongji-san route and the Seorak-san and Gyebang-san route, for migration of ancestral C. kyebangensis into South Korea. The MSNs (MSN-A and -B) elucidate migration routes well within South Korea, especially the route of Group I and Group II.

Esophageal cancer is a mjaor health problems in many parts of the world. 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 esophageal cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. The highest degree of spread was in Germi town and the least was in Ardabil city. There was a significant relationship between effective environmental factors and esophageal cancer in Ardabil province. The results indicated that environmental factors probably are influential in determining the incidence of esophageal cancer. Also, these results can be considered as a window to future comprehensive research on esophageal cancer and related risk factors.

The purpose of this study was to identify the origin of diversity of costume material caused by environmental difference. For this purpose, this research involved theoretical studies and studies based on historical data obtained from previous related studies. The common truth was proved that environmental including the geographical distribution of plants and animals determines costume material. Also, It was found that the unique traditional costume styles were developed through unique combination of costume material and their culture. The major results of this study are as follow : 1. The traditional costume of North American Indian was well-developed and closely related to geographical distribution of plants and animals. Also, their costume was so diverse that it could not be categorized. 2. The traditional costume of North American Indian showed ideal har mony between nature and human being surrounding environment into their costume. 3. The application of plants and animal materials into their costume was one of the environment-friendly human activity and it seems to give us an important message.

In this paper, GIS (Geographical Information System) for KODAS (Korea Distribution Automation System) will be presented. It has been developed to display the status of distribution power line facilities with background geographical map information (eg. address, street, railways and building) and provides various menu screen that can be handled easily. We will discuss computer system I/F between Host computer and GIS, DB structure for GIS and It's functions.

Psalidoremus is one of the subgenus which consists of five species and eleven subspecies through Taiwan, Japan, Korea and north eastern part of China which present strong endemism to their distribution. While most of advance studies focus on the new species or subspecies from this taxon, this paper suggests paleogeographical assumption and hypothesis of how they diverged from common ancestors. Phylogeographical patterns illustrated by the distribution of five species, which including Prosopocoilus inclinatus, Prosopocoilus hachijoensis, Prosopocoilus dissimilis, Prospocoilus pseudodissimilis, Prosopocoilus motschulskii respectively, has been assessed in this research. Speciation history is suggested by morphological tendencies especially in male mandibles with assumption from geographical patterns of under sea level.

도시화 지역은 지역발전과 더불어 공간적 범위가 확대되고 있다. 수도권 역시 예외는 아니어서 1960년대 이후 우리나라의 경제개발을 주도하며 도시화 지역의 공간적 범위가 확대일로에 있다. 그러나 도시화 지역의 공간적 분포를 평가함에 있어 그 분포 양상이 집적형태인지 임의적 형태인지 아니면 분산된 형태인지는 정확히 판단하기 어렵다. 즉, 시기가 지남에 따라 도시화 지역이 확대되기는 하지만 정량적으로 그 분포를 판단하기란 쉽지 않다. 본 연구는 GIS의 통계적 분석 기법을 이용하여 도시화 지역의 확대와 성장이 도시화 지역의 분포 패턴에 어떠한 영향을 주었는지를 살펴보고자 하는 것이다. 시계열적 도시성장 과정에서 수도권 내 도시화 지역의 분포패턴을 파악하고자 래스터 기반의 GIS 분석방법, 방격 분석(quadrat analysis), 그리고 최근린 분석(nearest neighbor analysis)을 사용하였다. 실험 결과 수도권의 도시화 지역의 집적정도는 1980년대 초반까지는 증가하다가 그 후로는 약화되는 것으로 분석되었다. 또한 1980년대 중반 이후 수도권 내에서는 외연적 성장이 약화되고 비지적 도시성장 또는 도로망과 연계한 소규모 개발이 증가함을 알 수 있었다.
