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.

기업결합에서의 경쟁제한성을 판단하는데 있어 지리적 시장의 범위를 획정하는 것은 매우 어려운 문제이다. 지리적 관련시장을 세계시장으로 획정하는 경우 국제시장의 정치, 경제적 복잡성을 무시하는 결과가 될 뿐 아니라 반경쟁적 행위를 허용하게 되는 위험이 있음도 부정할 수 없다. 그러나 오늘날 국제화가 진전되고, 특히 IT기술 등의 발전에 힘입어 지리적 관련시장이 확대되는 추세에 있는 점은 부인하지 못할 것이다. 독일의 경우 지리적 시장범위가 독일국내를 벗어날 수 있는 근거규정을 아예 입법화한 것도 이러한 추세를 반영한 결과의 하나가 아닌가 생각된다. 세계시장이 인정되기 위해서는 어떤 요소가 충족되어야 하는가에 대한 국내외의 사례분석이 필요하다고 본다.

기존 개발되어 왔던 센서 네트워크 시뮬레이터는 외부 환경적인 영향요소를 고려하지 않고 네트워크 중심적으로 설계 및 구현되어 왔다. 하지만 센서 네트워크의 사용 목적이 다양해지면서 센서 네트워크를 실내뿐만 아니라 실외 환경에도 적용하려 하고 있다. 실내보다 실외 환경에 센서 네트워크를 구축할 경우 가장 먼저 고려해야 할 사항은 초소형, 저전력의 특징을 가지고 있는 센서들을 배치하는 것이기 때문에 센서가 배치되는 지리적 요소를 고려해야 한다. 따라서 기존 센서 네트워크 시뮬레이터는 지리적 요소가 배제되어 있기 때문에 외부 환경에 적용하여 센서 네트워크를 시뮬레이션하게 되면 상당히 많은 차이점을 보일 수 밖에 없다. 따라서 본 연구에서는 외부 환경에 센서 네트워크를 구축 시 고려되는 핵심 영향요소 중 지리적 요소를 고려하여, 시뮬레이터에 접목시킬 수 있도록 세분화 및 분석하였다. 이를 통해 외부 환경에 센서 네트워크 구축 시 효율적으로 센서를 배치할 수 있도록 앞에서 분석한 지형 정보를 고려하여 센서 탐지 영역 감소율 분석을 위한 시뮬레이터 모듈을 설계한다.

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.

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.

In this study, we examine business start-up and closing business in a geographical context. In particular, we analyze the geographical characteristics of business start-up and closing business according to the type of industry. For the purpose, we use the last 10 years data that have been related with current economic situation since the financial crisis. In first, we identify the spatial distribution patterns of business start-up and closing business, We examine the difference between individual businesses and corporations. Finally, we construct general linear regression models and spatial regression models for them, and derive meaningful socioeconomic variables that explain their location distribution. The results of this study could provide basic data for regional planning of national and local governments that activate local economies as well as job creation.

Human life has been inextricably linked with healing. Recently, as the demands of healing are higher, it is more necessary to study spaces, places and mobilities related to healing in geographical studies. This paper draws on a case study of urban peoples walks along Seoul City Wall to explore what healing factors affect the people walking along historical landscapes in urban center and understand geographical implications of the healing process. Based on the concept and analytical lens of 'therapeutic mobilities' introduced by Gatrell, this research analyzes texts written on 181 blogs. The results show the main factors that affect their healing are 'weather climate', 'walk stroll', and 'nightscape'. Futhermore, the blogs' narratives focusing on these main factors imply healing place-making, time as limiting factor, and the social body within nightscape in the healing process.

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.

The purpose of this study is to develop documentation elements that can effectively record urban regeneration projects, focusing on port cities, in line with the historical background of urban regeneration projects. In order to develop recording elements, elements that need to be recorded were derived from eight fields, including geographical information, industrial information, and legal and administrative changes, from the Urban Regeneration Act, Port-related Act, and Urban Regeneration-related research. A Delphi survey was conducted three times targeting 20 experts related to urban regeneration to gather their opinions on elements derived from the Urban Regeneration Act, Port-related Act, and related research, and 32 final elements were derived. The recording elements for each selected area are geographical information(6), immaterial information(4), environmental maintenance(5), industrial and economic primary and secondary industries(2), and industrial and economic tertiary industries(3), changes(6), member participation(4), local legal and administrative systems(2). In addition, the applicability of urban regeneration documentation elements to local government records management experts was verified.

This study focused on the geographical concepts development and its zone of proximal development(ZPD) through the collaborative interaction. Among the conclusions are: 1) Students who have higher cognitive structure represented the Creator Seoul Metropolitan Area(GSMA) as a geographical concepts, not as a spontaneous concepts. The concepts is developed from concrete facts, subordinate element concept to basic element concept hierarchically. The most difficult concept that the learner should internalize was represented as the basic element concept. 2) Although ZPD of GSMA is individualized, it could be divided into 9 types. The ZPD was developed differently according to the qualitative differences how much more and how systematically represented the geographical concepts. The characteristics shown in this development procedure was that there was a quality change based on quantity extensive.
