  • The streamflow depletion due to groundwater pumping from deep aquifer near the Juksan stream has been simulated, in this study, by using the surface water and groundwater integrated model, SWAT-ODFLOW in order to analyze the relationship between the stream depletion and hydraulic properties of aquifer and streambed, and to spatially assess the streamflow depletion. The simulated results showed that the streamflow depletion rate divided by the pumping rate for each well location ranges from 10% to 90% with reflecting the various well-stream distance, transmissivity, storativity, and streambed hydraulic conductance. In particular, the streamflow depletion exceeds about 50% of pumping rate for conditions with transmissivity higher than $10m^2/day$ or storage coefficient lower than 0.1. The simulated results in the form of spatial maps indicated that the spatially averaged percent depletion of streamflow is about 53.6% for five years of pumping which is lower than that for shallow aquifer pumping by 12.9%. From the spatially distributed stream depletion, it was found that higher and more rapid stream depletion to pumping occurs near middle-downstream reach.

  • The purpose of this paper is to provide a better understanding of the unprecedented reform movement of geographic education in the United States since 1980 and extract some implications from this movement for geographic education in Korea. For the purpose, the history to this movement was reviewed through following three stages. In the first stage(1980~1984: form :HSGP" to :"Guideline"), the voluntary improvement movement appeared at California and the orgni-zational movement began in 1982 such as the Committee on Geography and International Knowledge. The national educational refrom imperatives, presented at "A Nation at Risk", and "Back to Basics" movement provided good opportunities to resurrect geography as a basic subject. For next real resurrection movement, the very important document "Guidelines for Geographic Education" was published at 1984. In the second stage(1985~1989: from "Guide-lines" to "Public"), the "Guideline" gave power-full motives and foci for reconstructiong the contents of geography, especially by the five fundamental themes(Location, Place, Relation-ships within Places, Movement, and Region). Also GENIP as the symbol of unity of all four major geography organization(AAG, NCGE, NGS, AGS) contributed to expanding and stren-gthening geography education. Also Geography Educagtion Program of NGS was a smart and well organized program to improve geographic education through it's a five strategies: Grass-roots organization(Alliances), Teacher education, Pu-blic awareness, Educational materials develo-pment, Targeted outreach to education decision-makers. In the late 1980s, the last focus of movement was the Public awareness and Edua-ction decision-making. In the third stage(1990-present: from "Public" to "Core Subject"), the initiative pendulum swung from geography organization to nation curricu-lum. In this National Curriculum, Geography was approved as a "Core Subject" and The 1994 National Geography Assessment Framework was constructed to assess the outcome of student's education in geography in grades, 4,8, and 12. Some Implications extracted from the process and contents of renaissance movement of geogr-aphic education in the Uinted States since 1980 are as follows. First, It shows the importance of the unity and target assignment among the geography organization. Second, interactive relationship between the academic geography and school geography develops each other. Third, teacher education, including pre-service education, including pre-service education and in-service education, is a key element to improve the quality of geography. And teacher organization is a good clearing house to exchange information for good geography. Forth, the positive and active response to changes in socketies such as globalism and inter-nationalizing, national education policy, and the trend of pedagogy is needed to rejuvenate geo-graphic education. Above all, we need to establish a well organized and powerfull program, sophisticated activities strategies, and long-term implementa-tion plan if we want more and better school geography.

  • Authors report a case of poststroke bipolar disorder that occurs much less frequently than poststroke depression(PSD). A MRI study performed to identify the etiology of a secondary manic episode in a patient with preceded PSD after left basal ganglia infarction revealed newly developed right basal ganglia infarction associated with poststroke bipolar disorder. It is interesting to note that (1) the temporal relationship was found between the occurrence of PSD after left hemisphere stroke and the occurrence of poststroke bipolar disorder following right hemisphere stroke, and that (2) the occurrence of PSD and the occurrence of poststroke bipolar disorder are associated with lesion location respectively. It has been reported that bipolar disorders were associated with subcortical lesions of the right hemisphere, whereas right-cortical lesions led to unipolar mania and that risk factors for mania included a family history of psychiatric disorders and mild subcortical atrophy. In this case, MR image shows subcortical lesions of the right hemisphere and mild subcortical atrophy. The investigation of the relationships among stroke lesion locations and potstroke mood disorders and risk factors for poststroke bipolar disorder may contribute to understanding the neurobiology of primary mood disorder. A clinical implication is that the risk of secondary bipolar disorder after cerebral infarction should be highlighted.

  • The construction of Daedeok Science Town, located in Yuseong ward of Daejeon metropolitan city, began in the early 1970s. It started out as a national project to form an agglomeration of the major central government research institutions. Since that time Daedeok Science Town has also attracted private research institutions, mainly during the 1900s. This study geographically analyzes this research institutions to clarify the regional identity of Daedeok Science Town through an integrated approach of existing new regional geography approach, which is characteristics of labour market as the regional pattern of its laborers' residences, spatial labour division, its research network with other institutions, and networks of university, research institution, and corporations, through the spatial spread of intellectual right of property and through network of technology business incubator relationship with spin offs which is appeared to spatial interaction. The results of the study are as follows: First of all, Daedeok Science Town was not only self-sustenance with marketing garden of agricultural regions in the suburb of Daejeon city but also was consign of agricultural products to Daejeon city before 1972. Since that time, the identity of Daedeok Science town has been formed by externally factors of the science development, by the local decentralization of population and public offices in Seoul metropolitan area in terms of the world economy system, and by the internally accessibility maximization of the central location in Korea between 1992 and 1999. On the part of Daedeok Science Town it has some merits of in-migration from nation-wide, and of mother city's Daejeon. Lastly at the period of the venture business beginning after 1999, the role of institution, developing the existing high technology, made great contribution to an attraction of ventures business to here in need of high technology industry growth, including knowledge-based industry in the informated society. On these bases, Daedeok Science Town seems to grow spontaneously as a science park.

  • This study analyzed the effect of career preparation behavior of female college graduates on their job satisfaction. The results of this study are as follows: First, the relationship between job satisfaction and career preparation behavior and a regression analysis of job satisfaction were all examined. This study used the original data from the Korea Employment Information Service for '2012 College Graduates' Occupation Route Survey'. The subjects of this study were 1,569 women in the science and engineering fields (649 engineering graduates, and 920 science graduates). The data was analyzed by frequency analysis, independent sample t tests, correlation analysis, and hierarchical multiple regression analysis using SPSS WIN 19.0. As a result, women with 4 years of college have higher job stability and job satisfaction than college students, but the reasons for major selection, university type, college location, and department. The results of this study are as follows. First, the effect of the variables on career satisfaction and job satisfaction was not statistically significant. This suggests that the type of college does not have a significant effect on job satisfaction if the university systematically prepares people for a career and the university suits a person's aptitude.

  • This survey research was performed to determine the social capital that public officials generate within the relationship of the community at the individual level by performing their public office work as an administrative duty. To this end, a survey was conducted on 500 civil servants in Jeju province. The survey period was May 19-23, 2014. 476 subjects were analyzed using a T-test, One way ANOVA, and multiple regression analysis to on SPSS 19.0Win software. As a result of the analysis, 1. The norms of the community cultural, male staff participation and cooperation, and social capital level of civil servants, showed a significantly higher association than female civil servants. There was a difference between the populations of registration to an association to the work location type. In addition, the social capital increases generally as the level of the officers increases. 2. The sub-category in the social capital of a personal level on civil servants family & associates trust, participation & cooperation and neighbor trust had a positive impact on the efficiency of public services. On the other hand, community cultural associations (network) did not have an influence on efficiency.

  • The objective of this research was to investigate the way information is used by pedestrians in underground space. Furthermore, we wanted to know how pedestrians utilize information from signage of signs by pedestrians. Thus, we conducted an investigation on the pedestrians' walking behavior in Fukuoka City, Tenjin underground shopping centers, and 1) checked routes taken by the subjects; and 2) categorized the signs that were observed, the pedestrians' movement patterns, the way information from signage isused by the pedestrians, the signs' locations, the relationship between the spaces, the heights of the signs and the types of signs offering directions. The results showed that there is a need to solve certain problems related to the locations of the signs and the walking behaviors of the subjects. To solve the problems exhibited by the subjects' walking behaviors, we came up with a variety of guidance information that could be used. The contents of the guidance information differ depending on the specified heights for the placement of signs and the information used depending on the location. The results also showed that the continuity between places needs to be shown more effectively by the guidance system, and that too many signs are positioned in places where the frequency of use is low.

  • Building the new administration capital city, one of presidential candidate Moo-Hyun Rho's election pledges, is now listed as a priority national policy agenda of the Participation Government. However, so many people's negative attitudes ranging from cynical skepticism to firm objections against the national policy agenda may threaten its smooth policy actualization. At this juncture, this paper attempts to present persuasive arguments and discuss some critical issues to be considered for building the new administration capital city successfully. The paper begins with taking a look at the current state of hyper-concentration of Seoul agglomeration area and its harmful effects, paints a vision of 'an evenly developed country as a whole' via illustrating the vision from the Swiss case, and reviews the performance of the precedent governments' reform measures for rectifying the hyper-concentration of Seoul agglomeration area. And then, the paper argues for building the new administration capital city as a potent solution to the problem of excessive concentration of activities in Seoul agglomeration area, as well as a driving force to spur the government to realize the Participation Government' enthusiastic vision: 'a decentralized and evenly developed country as a whole' and 'the hub country in the Northeast Asia'. In addition, the paper discusses the location of the new administration capital city in connection with the forthcoming national unification. Lastly, the paper deals with the important issues such as the procedure of people's approval, the population size and legal status of the new administration capital city, the relationship between building the new administration capital city and decentralization reform, etc.

  • Lately due to the sudden growth of the construction of an apartment complex in domestic market, many construction companies are eager to provide various public facilities to increase the apartment distribution rate. An introduction of a fitness center is popularized as a part of such development. There has been a continuing development in a private fitness based on analyzing the user's data. However a public fitness is quite different from the private in terms of a user's classification, preference rate, the pattern of use, and location which requires a different facility plan. Nevertheless, all these days a public fitness in an apartment house has been developed without a specific facility plan based on relevant materials. It is worried that such development would cause the facilities not to function as appropriate resident facilities and sink to idle ones. Therefore the purpose of this paper is to make the standard considered in facility planning in future and the base to guide an applying method. In the paper the present condition of fitness centers inside apartment houses has been compared to analyze the progress of the existing facilities and the appropriateness of the organization and the structure division. The result of the research shows that public resident facilities is not the place to perform passive role for fixed activities but one to form a community through the human relationship based on the facility. Therefore a fitness center inside the apartment complex have to be designed to provide service and leisure space as one of main community facilities for residents. To obtain this purpose, when choosing facilities of an apartment complex, first of all the residents' standard of living, apartment size, residents' distinction rate of age and sex, the needs of the times should be fully considered Secondly, the size of each facility space have to be decided based on the practical data analysis in facility use such as space preference, average staying time. Also, future living culture requires the change of the function and space according to the change of social values, so continuing research and data analysis are required to related to fitness center inside an apartment complex in order to present systematic approaching method and the paper will be expected to be a little step toward it.

  • Aerosol optical properties as well as vertical location of layer can alter the radiative balance of the Earth by reflecting and absorbing solar radiation. In this study, radiative transfer model (RTM) and satellite-based analysis have been used to quantify the top-of-atmosphere (TOA) radiative effect of aerosol layers in the cloudy atmosphere of the northeast Asia. RTM simulation results show that the atmospheric warming effect of aerosols increases with their height in the presence of underlying cloud layer. This relationship is higher for stronger absorbing aerosols and higher surface albedo condition. Over study region ($20-50^{\circ}N$, $110-140^{\circ}E$) and aerosol event cases, it is possible to qualitatively identify absorbing aerosol effects in the presence of clouds by combining the UV Absorbing Aerosol Index (AAI) derived from Total Ozone Mapping Spectrometer (TOMS), cloud parameters derived from the Moderate Resolution Imaging Spectro-radiometer (MODIS), with TOA Upward Shortwave Flux (USF) from the Clouds and the Earth's Radiant Energy System (CERES). As the regional-mean radiative effect of aerosols, 6 - 26 % lower the USF between aerosols and cloud cover is taken into account. These results demonstrate the importance of estimation for the accurate quantification of aerosol's direct and indirect effect.
