본 연구는 국내 문헌정보학 분야 학술지를 대상으로 협업 특성과 연구주제를 파악하기 위해 지리적인 측면에서 기관들의 공동연구 특성을 살펴보았다. 기존의 협업 특성을 분석한 연구들은 공저 네트워크의 속성이나 연구자들의 연구생산성, 소속기관 및 국가 비교 등 통계적 측면에 초점을 맞추어 분석을 수행해왔다. 본 연구는 기존 연구에서 주된 분석수단으로 사용해 온 통계적 분석 외에 연구자의 협업 연구주제와 연구자가 속한 기관 및 지역정보를 활용하여 협업 패턴을 파악하도록 하였다. 연구자가 속한 기관들 간의 협업 네트워크를 지리적인 관점에서 연구주제와 함께 직관적으로 파악할 수 있다는 장점이 있다.

A geographical indication is a protected trade name or mark for a product that corresponds to a specific geographic location or origin. Geographical indications have been widely used in European countries over the last three decades, mainly for wine and food products. This study investigates the consumer perception of geographical indications for agricultural and processed products and purchase experiences of consumers. It also examines consumer intention to pay more for geographical indication products. The findings from the empirical investigation showed that only 24.0% of the respondents have purchased geographical indication products whereas 49.5% of the respondents have not. Meanwhile, 26.5% of the respondents reported that they were unaware of geographical indications. Main reasons of purchasing geographical indication products were trust in quality, safety, and better taste. On the other hand, main reasons of not purchasing geographical indication products were lack of knowledge and no distinctive quality. The respondents answered that they would pay more for geographical indication products especially for luxury items such as ginseng, wine, and beef.

The effects of geographical and climatic factors on annual and monthly pan and Penman evaporation were analyzed. 52 climatological stations were selected and trend analyses were performed. Furthermore, cluster analysis and multiple linear regression analysis were performed to understand the effects of geographical and climatic factors on pan and Penman evaporation. Based on stepwise multiple linear regression analysis, annual pan evaporation is proved to be mainly controlled by urbanization as geographical factor, and annual pan evaporation is also controlled by temperature, relative humidity, wind speed, and solar radiation as climatic factor. Especially wind speed is considered to be most significant climatic factor which affects pan evaporation. Meanwhile, Penman evaporation is not affected by geographical factors but it is affected by climate factors such as temperature, relative humidity, wind speed, and solar radiation except precipitation. Furthermore, the study results show that only proximity to coast affects pan evaporation trend on July; however, geographical and climatic factors do not affect pan evaporation trends in annual basis and monthly basis (January, April, and October). On the other hand, Penman evaporation trends were not affected by geographical factors in annual and monthly basises.

This study explains a turning to being cultured and geography management to get closer to popularization and specialization of geography, for which based on the assumption that they are for development of knowledge. It adopts the idea of human's geographical nature to solve the dualism which geography is referred as science and art. An object geographer studies is homogeneous, temporal as well as identifical and individual. To adopt human's geographical nature causes to human's geographical investigation, and uniting positivism to humanism. It deduces from the Bible and Evolutionism that it is characteristic of mobility, adaptabilty, connectivity, ideality, and hybridity. Geographical concepts is based on the fact that it can be applied to geographical research theme. Popularization of geography has to relate to being cultural, and specialization of geography has to relate to geography management.

수자원에 대한 효율적 활용 요구가 증대됨에 따라 한반도 수리적 특성을 보다 정밀하게 모의하고 이를 활용한 의사결정이 요구되고 있다. 한반도는 지리적 특성상 약 70%가 산학 구조로 되어 있어서 지형적 기상 현상이 복잡하여 가뭄지수의 공간 보간에 어려움이 있다. 따라서 지형적 특성-거리, 고도, 해양에서의 거리, 지향면 등을 고려할 수 있는 PRISM 기법을 기존의 공간 보간 기법과 비교 분석하여 한반도 전역의 가뭄 특성에 적합한 공간 보간 기법을 검출하고자 하였다. 자료의 분석은 기상청에서 제공하는 강우 관측소중 40년 이상의 연한을 가지고 있는 60개 지점을 선정하여 분석하였으며 방법 간의 비교는 지점을 선정하여 추정된 오차를 기초로 하여 판단하였다. 분석결과 PRISM 기법이 복잡한 지형적 특성을 가진 지역에서 더 적합한 방법으로 나타났다. 향후 연구에서는 미개측 지역의 가뭄지수 분석을 시행하여 관측소가 설치되지 않은 지역의 적합한 가뭄 특성을 분석하여 효율적인 수자원 활용을 위한 적절한 의사결정 지표를 선정하고자한다.

Human capital and higher education have been increasingly emphasized with the rise of a knowledge-based economy. Cities are recognized as places to attract human capital and spur economic development. Educated workforce supply is one of the critical parts to sustain IT industries, which have been leading recent economic development. This paper examines factors affecting geographies of educated workforce supply from colleges and universities to companies in U.S. metropolitan areas through questionnaire survey and interviews with IT companies and IT-related programs at colleges and universities. The results show that: (1) physical proximity between IT companies and colleges/universities enhances the degree of educated workforce supply from colleges/universities to IT companies; (2) IT companies which seek more specialized and rarer expertise recruit the workforce from colleges or universities over longer distance; (3) colleges and universities which offer a higher degree have geographically more extensive supply of educated workforce to IT companies than those which offer a lower degree; and (4) large IT companies have more geographically extensive supply of educated workforce to colleges/universities than small IT companies.

It is increasingly clear that student mastery of concepts and skills in geographic education is based on a complex set of variables. Sex and gender are the key variables. Much has been written about biological sex differences in learning, but less attention has been paid to the impacts of socio-cultural gender on learning geography. As such, the aims of this paper are two-fold. First, to examine theories which seek to explain why males and females might differ in their geographic and spatial knowledge or skill. Second, to examine the extent of sex differences and gender traits in the geographic learning. The results of study illustrate clearly that there are more similarities than differences between the sexes. Therefore, there are significant gender differences between the preferences of regions, contents, activities in the secondary geographic learning. The results also provide insights into improving contents and method of geographic education.

Radio navigation aids are very important elements to provide information necessary for safe navigation using radio waves. Recently, the number of radio equipment using radio waves is increasing, and the air frequency interference by adjacent channels is very high. In addition, the use of irregular jamming that threatening radio navigation aids and satellite navigation system frequency is rapidly increasing. Therefore, it is urgent to ensure the safety of air waves. In this paper, we investigated the characteristics and frequency of the domestic navigation system. And we were analyzed the geographical separation standard for implementation of analysis program. Also, we implemented a program for the geographical separation distance analysis that applying international standards and recommended practices.
