일제강점기인 1910년에 작성된 1:50,000 지도(이하 근세 한국 오만분지일 지형도)는 전국을 망라한 최초의 근대적 방법에 의해 제작된 지도이다. 본 지도는 주로 인문 지리적 관점에서 이용되어 왔으나 최근 지도의 높은 정확성이 인식됨에 따라 다양한 분야에서 유용하게 되었다. 특히 해안분야에 있어서는 해안 구조물 건설에 따른 장기적인 지형변화를 제공할 것으로 기대된다. 본 연구는 독립된 해안 표사계에 대해 구조물의 건설 전후에 진행된 지형변화의 분석방법에 관한 것이다. 장기적인 해안의 지형변화를 분석하기 위한 기점은 1910년도의 지형도로 하였다.

일제가 한반도를 본격적으로 수탈할 목적으로 조선총독부를 통하여 1914년에서 1918년까지 5년간 제작한 축척 1:50,000의 '근세한국 오만분지일 지형도'는 근대적인 토목공사에 의한 개발이 본격적으로 진행되기 이전인 구한말 한반도의 삶의 모습을 그대로 담고 있는 자료이다. 이 연구에서는 1910년대의 경관을 담고 있는 근세한국 오만분지일 지형도 이미지에 좌표를 부여한 후, GIS 환경에서 오늘날의 지도와 중첩하여 토지이용변화를 분석하였다. 연구 결과 근대적인 토목공사가 시작되기 이전에는 개발이 어려웠던 구릉지역과 잦은 침수로 인하여 방치되고 있던 하천부지, 산업구조의 변화로 인하여 경쟁력을 상실한 농경지 등이 오늘날에는 도시지역으로 개발되었다.

대동여지도의 공간적 정확성을 측정하기위하여 이를 현대지도와 비교할 경우 가장 문제되는 것의 하나가 현대지도의 도법이며 이는 곧바로 대동여지도의 도법과 연관된다. 본 연구에서는 이러한 비교를 위하여 대동여지도의 도법을 각종 도법에 의한 현대지도와 대동 여지도의 유사성, 김정호와 관련된 지지 또는 지도의 기록, 그리고 대동여지도의 제작자료를 중심으로 검토하였다. 그 결과 대동여지도의 도법으로는 몇가지의 가능성이 있으나 현재 대 축척의 지형도와 같은 지도의 제작에 사용되고 있는 TM 도법이 적절할 것으로 판단되었다.

현대문학은 사회적 배경에 따라 그 시대적 상황을 표현하여 왔다. 즉 시대가 변하면 문학작품도 변화를 가져왔다. 따라서 우리는 현대문학을 통해 그 시대를 이해할 수 있고, 그 시대의 사회적 요구를 습득할 수 있다. 이러한 문학작품들은 정보통신의 발달에 따라 미디어 매체로 제작됨으로서 사용자들에게 보다 가까이 접근하는 계기를 만들어 주고 있다. 최근, IT 융합, 디지털 융합이라는 새로운 학문의 기류는 서로 다른 학문분야를 접목하여 보다 많은 시너지 효과를 가져 오고 있다. 따라서 본 논문은 현대문학작품들을 디지털화 하는데 필요한 온톨로지를 설계하고자 한다. 이를 위하여 시대별 문학작품의 구조를 분석하고 각 요소들과의 관계를 명세한다. 명세의 방법은 토픽맵을 이용하였다. 또한 각 관계 모델은 토픽벡터를 통해 연결을 명세하였다.

This study aims at examining the background and development process of Masan city after Koryo Dynasty, making a reconstructive map of Original Masan using the first registration maps made in 1912 and analyzing the urban structure of the Original Masan area. The origin of Masan city went back to Koryo dynasty. Around 1040 Koryo government placed an official shipping facility in Masan to transport the taxed grain to the capital city. After that Masan became an important port covering the southern part of KyungSang-Do. And the urbanization of the Original Masan began to bud after a shipping facility was again established by the Chosun Dynasty in 1760 and strengthened in the 19th century after the social standing system was broken and many peasants moved to cities as daily workers. In 1899 Masan was forced to be opened to foreign powers and they placed an international settlement distanced from the area(Original Masan). After this many Japanese advanced to the international settlement and further to the area. The advancement of Japanese brought a critical change in the urban structure of the area. Land was owned by Japanese and many modern sysytems were introduced such as modern buildings, new roads, railroad and modern factories. According to the reconstructive map of the area, 80.5% of land lots are less than $200m^2$ showing the size of each land lot is comparatively small. And Japanese occupied 31.5% of the land in the area. Their land was located on the stratigic points near the port and the center of commerce. The ratio of the road area to the whole land was around 14%, not so low for urban areas in that time. The reconstructive map reveals the exact coastline of the year 1912 erased now due to filling the sea and extending the land, Present Masan city has been developed having the Original Masan as its nucleus. The area has been always the center of urban activities for Masan city. Making an exact reconstructive map for the area and analyzing the urban structure of the area in 1912 is a very important work to understand Masan city wholy.

Most current 3D digital maps are 2.5 dimension models based on DEM, which can only be recognized, browsed and operated by a special software, far from meeting the needs of a modern digital city (global) with the distributed, isomerous and multiple application on the real 3D representation and open sharing models. In this paper, a new generation digital city oriented 3D digital map is studied. Firstly, a real 3D digital map representation is presented. And then, some key techniques and methods for browser-based 3D digital map’s representation, display and operation are introduced, which can realized the open sharing of 3D map in distributed, isomerous and multiple application environment. Furthermore, the scale driving technique of proposed 3D digital map is also studied. And currently, some developments based on some of the above methods are being carried to provide key and general platform for other application software’s development.

Modern speaker verification systems based on support vector machines (SVMs) use Gaussian mixture model (GMM) supervectors as their input feature vectors, and the maximum a posteriori (MAP) adaptation is a conventional method for generating speaker-dependent GMMs by adapting a universal background model (UBM). MAP adaptation requires the appropriate amount of input utterance due to the number of model parameters to be estimated. On the other hand, with limited utterances, unreliable MAP adaptation can be performed, which causes adaptation noise even though the Bayesian priors used in the MAP adaptation smooth the movements between the UBM and speaker dependent GMMs. This paper proposes a sparse MAP adaptation method, which is known to perform well in the automatic speech recognition area. By introducing sparse MAP adaptation to the GMM-SVM-based speaker verification system, the adaptation noise can be mitigated effectively. The proposed method utilizes the L0 norm as a regularizer to induce sparsity. The experimental results on the TIMIT database showed that the sparse MAP-based GMM-SVM speaker verification system yields a 42.6% relative reduction in the equal error rate with few additional computations.

Today is a 'high concept' era in which consumers make sensible consumption that shares a sensible bond with a brand. Therefore, it is important to analyze consumers' aesthetic awareness; namely, fashion feeling in the fashion industry. This study conducted research into a fashion design planning process according to a fashion feeling focusing on computer graphics suited to the 21st century digital trend. First, the study classified a fashion feeling with eight senses including elegance, classic, modern, mannish, sporty, avant-garde, ethnic, and romantic feelings. Second, the study made an image map, color map, material map, and style map with Adobe Photoshop CS3 by dividing a fashion planning process with a computer graphics program. Also, the study made a flat illustration with Adobe Illustrator CS3. Third, the study proposed the image map, color map, material map, style map, fashion illustration and flat illustration in the design planning process under the theme of the aforementioned eight fashion feelings.

Modern society has moved from a phosphorus recycling loop, where animal manure and human wastes were spread on farming land to recycle nutrients, to a once-through system, where phosphates are extracted from mined, non-renewable phosphate rock and end up either in landfill(sewage sludge, incinerator ash) or in surface waters. In this research, crystallization of nitrogen and phosphate with natural sources of $Mg^{2+}$ in synthetic water was tested. The operational parameters of pH, mixing time, and the magnesium molar ratio were investigated to find optimal conditions of the MAP precipitation using synthetic wastewater. The removal efficiency of phosphate increased with pH up to 11. By MAP precipitaiton of the synthetic waste water, 94% of the phosphate were eliminated at pH 11. It was found that at least 10 minutes mixing time was required and 20 minutes mixing time was recommended for efficient phosphate removal. High efficiency removal of phosphate was possible when the magnesium molar ratio was 1.0~2.0. The comparative study of different magnesium sources showed that coagulants (PAC) was the more efficient sources than only magnesium. The result showed that 97% of phosphate removal. In conclusion, coagulants (PAC) induced crystallization of struvite and hydroxyapatite was shown to be a technically viable process that could prove cost effective for removing phosphate in wastewater.

Efficiency and limitations of HAZUS-MH, a GIS based systematic and informative system developed by FEMA and NIBS for natural hazard loss estimations, are discussed by means of a pilot study in the Korean Peninsular. Gyeongsang-do has been selected for the test after careful reviews of previous studies including historical and modern seismicity in the peninsular. A ShakeMap for the selected scenario earthquake with magnitude 6.7 in Gyeongju area is prepared. Then, any losses due to the scenario event have been estimated using HAZUS. Results of the pilot test show that the study area may experience significant physical, economic and social damages. Detailed study in the future will provide efficient and crucial information to the decision makers and emergency agents to mitigate any disaster posed by natural hazards.
