  • 우리들은 초 중등교육을 통해 암석의 종류와 특징, 지질형태와 퇴적구조, 그리고 화석에 대해 지속적으로 교육 받아왔다. 그러나 암석이나 노두를 보고 학교에서 배운 지식을 바르게 적용할 수 있는 학생은 매우 드물다. 또한 아름다운 경관을 보며 지질학적으로 형성과정을 해석할 수 있는 사람도 매우 드물 것이다. 여기서는 지질경관에 대한 정보를 어떻게 제공하고 있는가에 대한 연구 성과를 정리해보고 문제점을 도출하고자 한다. 현재까지 지질경관을 알려주는 연구 성과를 크게 나누면 3종류가 있다. 첫째, 지질학습장의 개발 및 활용에 관한 연구이다. 이 부류의 수집된 자료는 학위논문(29편)과 전문학술지(27편)로 현재 56편이나 검색에 따라 더 늘어날 것이다. 이들은 야외 노두에 대한 효과적인 지질학습을 위한 자료개발을 위주로 하고 있다. 이러한 내용들은 전문가 양성에는 대단히 좋은 프로그램이지만 청소년이나 일반대중들에게 너무 어려운 내용으로 구성되어 있다. 또한 교육청에서 주관하는 탐방계획으로 "경기도 지구과학교사 연구회"가 있는데, 주로 경기도 한탄강유역을 대상으로 하고 있다. 이 연구회 자료에서는 지역의 특성을 살린 야외지질학습장을 개발하고 현장에 적용하기 위한 노력을 볼 수가 있다. 두 번째로 과학전람회 자료로서 현장교사와 학생들의 야외학습에 대한 인식이 잘 나타나 있다. 수집된 자료는 총 55편으로 야외지질조사를 통해 관찰 자체에 중점을 두었는데, 최근에는 노두관찰에 덧붙여 탐구학습 태도와 창의성을 함양하는 쪽으로 옮겨가고 있다. 세 번째 자료는 일반대중을 위한 서적이다. 이 서적들은 저자들의 전공에 따라 그 내용이 다소 다르다. 즉 일반여행안내 책자는 노두나 암석은 소개하고 있으나 지질학적 설명이 전혀없으며(예, 남도해안 2000리), 지리학자들의 저술에는 지형의 형성을 지질학적으로 설명하려 애쓴 흔적이 보인다(예, 한국지리이야기). 다음으로 지구과학들의 저술은 전형적인 지질답사 안내서에 가까워 내용 자체는 좋으나 흥미가 다소 떨어진다(예, 가족이 함께 떠나는 지질여행, 제주도 지질여행). 지질학과 흥미를 적절히 혼합한 책으로 '우리 땅 과학 답사기'정도가 있다. 최근 한국암석학회에서는 "우리의 명산"을 지질과 경관의 관점에서 해석하려는 심포지엄을 2차례 가졌다. 그러나 그 내용면에서는 경관지질이라는 개념을 정립했다고 보기에는 다소 미흡 하나, 황상구 교수의 주왕산에 관한 내용은 앞으로 경관지질 연구에 대한 발전의 여지를 보여주었다. 앞으로 지질경관에 대하여 지질학적 야외답사나 과학지식 습득에 국한시키지 말고, 그 지역의 특성을 살린 관광 또는 민속과 연계하여 지구과학적 학습효과와 더불어 인성교육에 도움이 되는 학습 콘텐츠를 개발하도록 노력해야 할 것이다. 일반 대중이 우리나라의 빼어난 지질 경관을 손쉽게 이해하고 즐기게 되면, 세계자연유산이나 세계지질공원을 지정 받는 과정도 더 쉬워질 것이다.

  • This study critically examines the social and personal meanings that luxury consumption have in contemporary Korean society through understanding the consumption experiences of men in their 30s. Interviews with nine male consumers who are committed to luxury brands, especially those that produce suits, watches, fountain pens, and shoes, were conducted to collect qualitative data. We found that participants are satisfied with the whole process of luxury brand consumption including buying, using, and managing and try to consume the products for self-expression, congruent with their lifestyle and identity. Individuals have learned how to consume the luxury brand from their role models. Their consumption follows hybrid and postmodern patterns and combines luxury brand products with non-luxury one. In contemporary Korean society, using the luxury products is considered necessary to achieve some advantages in social contexts and can be also functioned as a sort of social signifier and self-help, as well as, a tool for self satisfaction or well-being.

  • In this study was classified the cadastral control points and parcel boundary points into 40m, 100m by flight altitude of UAV (Unmanned Aerial Vehicle) which compared the coordinates extracted from the orthophoto with the parcel boundary point coordinates by GNSS (Global Navigation Satellite System) ground survey. As a results of this study, first, in the spatial resolution analysis that the average error of the orthoimage by flight altitude were 0.024m at 40m, and 0.034m at 100m which were higher 40m than 100m for spatial resolution of orthophotos and position accuracy. Second, in order to analyze the accuracy of image recognition by airmark of flight altitude that was divided into three cases of nothing, green, and red of RMSE (Root Mean Square Error) were X=0.039m, Y=0.019m and Z=0.055m, the highest accuracy. Third, the result of the comparison between orthophotos and field survey results that showed the total RMSE error of the cadastral control points were X=0.029m, Y=0.028m, H=0.051m, and the parcel boundary points were X=0.041m, Y=0.030m. In conclusion, based on the results of this study, it is expected that if the average error of flight altitude is limited to less than 0.05m in the legal regulations related to orthophotos for cadastral surveying, it will be an economical and efficient method for cadastral survey as well as spatial information acquisition.

  • The geography, circulation pattern, and ecology show that the semi-closed seas of Northwest Pacific be managed as one complete system. Ongoing multilateral cooperative efforts relevant to marine environmental protection in the Northwest Pacific area, include the Working Group for the Western Pacific (WESTPAC) established under the auspices of WNESCO's Intergovernmental Oceanographic Commissions, the UNDP/GEF Programme on Prevention and Management of Marine Pollution in East Asian Seas (PEMSEA), the North Pacific Marine Science Organization(PICES), and the United Nations Environment Programme(WNEP)'s Northwest Pacific Action Plan(NOWPAP). The present report firstly describes the current situations on the existing regional cooperative regimes for marine environmental conservation in the Northwest Pacific region, with a special respect to the Northwest Pacific Action Plan(NOWPAP) which was adopted in 1994 by Japan, People's Republic of China, Republic of Korea and Russian Federation. Then, problems of the existing regimes are also discussed, together with the suggestion of the possible solutions, focusing on NOWPAP. Suggestions include: 1) the Northeast Asian countries should understand the importance of legally-binding regional convention, and should build up any legally-binding instrument which can function as a big umbrella for real regional cooperation without prejudice to the rights of the States, 2) At present stage, it will be possible to make a regional convention flexible without prejudice to the sovereign right of the States or territorial issues; 3) taking into account that the region often faces many generic political problems that often inhibit the effective collective actions on environmental issues, the leadership from UNEP or other international organizations is required; 4) strong institutional and financial framework should be made, and 5) multilateral efforts to respond to the new marine environmental threats should be taken at the regional level in order to protect the coastal and marine environments in the Northwest Pacific.

  • In this thesis, GPS and the electronic mapping were used to realize such a system by recognizing license plate numbers and identifying the location of objects that move at synchronous times with simulated movement in the electronic map. As well, throughout the study, a camera attached to a PDA, one of the mobile devices, automatically recognized and confirmed acquired license plate numbers from the front and back of each cu. Using this mobile technique in a wireless network searches for specific plate numbers and information about the location of the car is transmitted to a remote sewer. The use of such a GPS-based system allows for the measurement of topography and the effective acquisition of a car's location. The information is then transmitted to a central controlling center and stored as text to be reproduced later in the form of diagrams. Getting positional information through GPS and using image-processing with a PDA makes it possible to estimate the correct information of a car's location and to transmit the specific information of the car to a control center simultaneously, so that the center will get information such as type of the cu, possibility of the defects that a car might have, and possibly to offer help with those functions. Such information can establish a mobile system that can recognize and accurately trace the location of cars.

  • The classification accuracy of land cover has been considered as one of the major issues to estimate pollution loads generated from diffuse landuse patterns in a watershed. This research aimed to assess the effects of the acquisition methods and sampling size of training reference data on the classification accuracy of land cover using an imagery acquired by optical sensor(OPS) on JERS-1. Two kinds of data acquisition methods were considered to prepare training data. The first was to assign a certain land cover type to a specific pixel based on the researchers subjective discriminating capacity about current land use and the second was attributed to an aerial photograph incorporated with digital maps with GIS. Three different sizes of samples, 0.3%, 0.5%, and 1.0% of all pixels, were applied to examine the consistency of the classified land cover with the training data of corresponding pixels. Maximum likelihood scheme was applied to classify the land use patterns of JERS-1 imagery. Classification run applying an aerial photograph achieved 18 % higher consistency with the training data than the run applying the researchers subjective discriminating capacity. Regarding the sample size, it was proposed that the size of training area should be selected at least over 1% of all of the pixels in the study area in order to obtain the accuracy with 95% for JERS-1 satellite imagery on a typical small-to-medium-size urbanized area.

  • Spatial data integration using multiple geo-based data sets has been regarded as one of the primary GIS application issues. As for this issue, several integration schemes have been developed as the perspectives of mathematical geology or geo-mathematics. However, research-based approaches for statistical/quantitative assessments between integrated layer and input layers are not fully considered yet. Related to this niche point, in this study, spatial data integration using multiple geoscientific data sets by known integration algorithms was primarily performed. For spatial integration by using raster-based GIS functionality, geological, geochemical, geophysical data sets, DEM-driven data sets and remotely sensed imagery data sets from the Ogdong area were utilized for geological thematic mapping related by mineral potential mapping. In addition, statistical/quantitative information extraction with respective to relationships among used data sets and/or between each data set and integrated layer was carried out, with the scope of multiple data fusion and schematic statistical assessment methodology. As for the spatial integration scheme, certainty factor (CF) estimation and principal component analysis (PCA) were applied. However, this study was not aimed at direct comparison of both methodologies; whereas, for the statistical/quantitative assessment between integrated layer and input layers, some statistical methodologies based on contingency table were focused. Especially, for the bias reduction, jackknife technique was also applied in PCA-based spatial integration. Through the statistic analyses with respect to the integration information in this case study, new information for relationships of integrated layer and input layers was extracted. In addition, influence effects of input data sets with respect to integrated layer were assessed. This kind of approach provides a decision-making information in the viewpoint of GIS and is also exploratory data analysis in conjunction with GIS and geoscientific application, especially handing spatial integration or data fusion with complex variable data sets.

  • In this paper I will undertake three tasks: first, to identify the difference between John Rawls's liberal conception of liberty and Will Kymlicka's; second, to briefly examine the problems with liberal conception of liberty; finally, to propose a certain alternative that will be able to make liberal conception of liberty more meaningful In Kymlicka's view, Rawls seems to fail to make the best defence of freedom of choice because he wants to explain of individual freedom on the basis of Kant's moral theory about liberty. Kymlicka thinks that it is not a desirable way of defending liberal conception of liberty. According to his liberal theory, Rawls's defence of freedom of choice might make us think that we should have our freedom of choice for its own sake because freedom is the most valuable in the world. So Kymlicka wants to provide stronger argument to defend freedom of choice in liberalism. He insists that it is our projects and tasks that are most important things in our lives. Furthermore, he argues that we should conceive our freedom of choice as a precondition for pursuing those projects and practices that are valued for our good lives. Now I want to look at two concepts of liberty in liberalism with Rawls's theory and Kymlicaka's. In this paper, I shall look at criticisms of the liberal account of freedom of choice. These would give us a certain chance for understanding true freedom.

  • The recent success of populist parties and candidates in the US and European countries leads to a massive amount of empirical research on populism, a deviant form of representative democracy. Much ink has been spilled to define populism and to identify the causes of its rise and continued success in democratic political system. However, little is known about populist attitudes of individual voters. Using a large-scale online survey fielded in the context of the South Korean presidential election in 2017, this study examines (1) what determines populist attitudes of South Korean voters and (2) how populist attitudes are associated with evaluations of political parties, candidates, and political issues. Statistical analysis reveals that people high on populism are more likely to support an underdog left-wing political party and its presidential candidate, and are less likely to support policies implemented or proposed under the auspices of the Park Geun-hye administration. These findings do not necessarily suggest the inherent affinity between populism and left-wing ideology; rather, it implies populist attitudes happened to appear in 2017, in reactions to lack of confidence in the previous government.
