A force support system is composed of capital components such as combat equipments, supplies and so on to enable constant fighting power capability. Private technology level evaluation is on the rise as an important spin-on method in force support systems, which requires 92% of total munitions requirements, to obtain superior private technology. The evaluation of the private sector technology level on Korean force support systems has been conducted for the first time as follows: this research chose 38 items to be acquired within 2-3 years and grouped either identical or similar technology among those 38 items. A technology evaluating method was established based on the analysis of domestic and foreign technology level evaluations. Evaluation was performed by a Delphi survey from 180 private and military experts. To obtain an objective index and raise political availability, a technology system map and standard document were developed and applied to all 38 items.

Gwanghwamun was dismantled and displaced to the east side of the palace, at that time, the Chosun Government General Building was constructed in the Gyeongbokgung palace. After the Korea war, it remained as a stonework as a result of the fire. In 1968, The Gwanghwamun came back in front of the palace. Then, why it was rebuilt in the 3rd Republic period? What was the reason for selecting concrete? Since the May 16 coup, the military regime had been utilized palace and surrounding urban space to show a visible practice of modernization. Attempting the combination of modern technology in the 1960s and traditional cultural property and reconstructing a city as a pretext called Cultural Heritage conservation was a typical mechanism of the 1960s. In this study, I start by assume that reconstructing Gwanghwamun(1968) was a part of project to change the surrounding urban space of Gwanghwamun than to preserve cultural assets. Two main contributions of the study are following. First, I collect availabe data on the reconstructing surrounding urban space of the Gwanghwamun and re-organize them in chronological order to make them as fragments of a map. Second, I analysis and identify the nature and phase of the Gwanghwamun reconstruction.

An efficient outdoor local localization method is suggested using multi-sensor fusion with MU-EKF (Multi-Update Extended Kalman Filter) for car-like mobile robots. In outdoor environments, where mobile robots are used for explorations or military services, accurate localization with multiple sensors is indispensable. In this paper, multi-sensor fusion outdoor local localization algorithm is proposed, which fuses sensor data from LRF (Laser Range Finder), Encoder, and GPS. First, encoder data is used for the prediction stage of MU-EKF. Then the LRF data obtained by scanning the environment is used to extract objects, and estimates the robot position and orientation by mapping with map objects, as the first update stage of MU-EKF. This estimation is finally fused with GPS as the second update stage of MU-EKF. This MU-EKF algorithm can also fuse more than three sensor data efficiently even with different sensor data sampling periods, and ensures high accuracy in localization. The validity of the proposed algorithm is revealed via experiments.

This study examines the spatial structure of Jeju-eupseong (Town-castle) in the Joseon Dynasty. The spatial structure of Jeju-eupseong has distinctive features and regional characteristics that are substantially different from typical eupseong in inland regions. This is mainly attributed to the geographical characteristics of the island and the administrative system with strengthened military functions. Jeju-eupseong displays a distinctive layout of major buildings and road system with a plaza located in its center in comparison with the ones found in inland regions. Gwandeokjeong Plaza in Jeju-eupseong served as the center of Jeju's politics, administration, and culture during the Joseon Dynasty, and it, in the modernization period, has become an open public space in the heart of Old Downtown used for community gatherings. Therefore, this study aims to explore the historical background and distinctive spatial structure of Jeju-eupseong in comparison with eupseong in other parts of Korea. Moreover, the study examines the characteristics of Gwandeokjeong as a plaza that has not been dealt with in other studies of eupseong.

Most previous studies on A Gesture Life focused on illuminating the role and significance of Kkutaeh, the Korean comfort woman, whom Hata runs across at a military camp in the Burmese jungle. For instance, Carroll Hamilton argues that the return of Kkutaeh as a traumatic subject disrupts Hata's nationalist narrative, causing the protagonist's eventual failure at national enfranchisement. However, this paper focuses on Hata's relationship with Bedley Run, the sleepy suburban white town, in which the protagonist settles down right after immigration to the US. The racial/racist nature of Bedley Run has not received due critical attention, although a few studies on the novel saw Hata's gestures as a survival tactic deployed against the hostile environment of his new host society. This paper, resorting to Pierre Macherey's thesis on symptomatic reading, exposes what Hata, the narrator/protagonist, hides from his readers concerning his status in his muchbeloved town; and it also explores the subversive significance of Hata's ethnic memories. The aim of this study is, after all, to map both the subversive possibilities and the limitations of Hata's immigrant narrative as a bildungsroman.

Those land cover maps have widely been used in various fields, such as environmental studies, military strategies as well as in decision-makings. This study proposes a method to extract training data, automatically and classify the cover using ingle satellite images and national land cover maps, provided by the Ministry of Environment. For this purpose, as the initial training data, those three were used; the unsupervised classification, the ISODATA, and the existing land cover maps. The class was classified and named automatically using the class information in the existing land cover maps to overcome the difficulty in selecting classification by each class and in naming class by the unsupervised classification; so as achieve difficulty in selecting the training data in supervised classification. The extracted initial training data were utilized as the training data of MLC for the land cover classification of target satellite images, which increase the accuracy of unsupervised classification. Finally, the land cover maps could be extracted from updated training data that has been applied by an iterative method. Also, in order to reduce salt and pepper occurring in the pixel classification method, the MRF was applied in each repeated phase to enhance the accuracy of classification. It was verified quantitatively and visually that the proposed method could effectively generate the land cover maps.

This study is to measure the length of the Demilitarized Zone and the Military Demarcation Line(MDL) on the Korean Peninsular. For this purpose, maps of the Armistice Agreement Volume II were used. These maps are nine sheets. In order to extract the MDL shown on the map, coordinates were assigned to the scanned image maps using the georeferencing module of ArcGIS based on the sheet line coordinates. The accuracy of the extracted vectors was checked by overlaying them on the maps of the Armistice Agreement Volume II. And I tried to validate these vectors through comparative analysis with vectors extracted from Kim(2007). Vectors extracted from Kim(2007) had errors in the curvilinear parts of the MDL, but the vectors extracted from this study exactly matched the MDL in the Armistice Agreement Volume II. The measured length is 239.42km(148.77miles). This means that the expression '155mile MDL' or '248km DMZ' in papers, reports or mass media has so far been inappropriate. I think this study will be able to provide information on the exact length of the DMZ in studies related with DMZ or in policy decisions by the national and local government. However, it is deemed necessary to verify this result by national organizations such as the NGII(National Geographic Information Institute). After these verification procedures, I hope that the national government will inform the people of the exact length of DMZ and MDL.

Because of the global warming, the Arctic Ocean is expected to be ice-free by the year 2035. When the Arctic Ocean will be opened, a number of national interests will become more salient as experiencing a shortened sailing distance and decreasing navigation expense, possibility of natural resources transport by sea from Arctic Circle, and indirect-profit making by building a herb port in Asia. To secure the national interests and support the free activities of people in this region, R.O.K government is trying to make advanced policies. In order to carry out the naval tasks in the Arctic Ocean, using the operational characteristics(mobility, flexibility, sustainability, presence of capabilities, projection) is necessary. To this end, ROK Navy should analyze the operational environment (O.E.) by its capability(weakness and strength), opportunity, and threat. R.O.K. Navy should make an effort over the following issues to implement the tasks in the Arctic Ocean: first, Navy needs to map out her own plan (Roadmap) under the direction of government policies and makes crews participate in the education·training programs in home and abroad for future polar experts. Third, to develop the forces and materials for the tasks in cold, far operations area, Navy should use domestic well-experienced shipbuilding skills and techniques of the fourth industrial revolution. Next, improving the combined operations capabilities and military trust with other countries in the Arctic region to cover the large area with lack of forces' number and to resolve the ports of call issues. Lastly, preparation in advance to execute a variety of missions against military and non-traditional threats such as epidemics, HA/DR, SOLAS, in the future operation area is required.

The objective of this paper is to extract and analyze the sediment environment change information in the Sachencheon, Gangneung, Korea that was seriously damaged as a result of typhoon Rusa aftermath early in September, 2002 using multi-temporal remote sensing data. For the extraction of change information, an unsupervised approach based on the automatic determination of thresholding values was applied. As the change detection results, turbidity changes right after typhoon Rusa, the decrease of wetlands, the increase of dry sand and channel width and changes of relative level in the stream due to seasonal variation were observed. Sedimentation in the cultivated areas and restoration works also affected the change near the Sacheoncheon. In addition to the change detection analysis, several environmental thematic maps including microtopographic map, distributions of estimated amount of flood deposits and flood hazard landform classification map were generated by using remote sensing and field survey data. In conclusion, multi-temporal remote sensing data can be effectively used for natural hazard analysis and damage information extraction and specific data processing techniques for high-resolution remote sensing data should also be developed.

Jang Sang-Hoon(장상훈) concluded that Dongyeo(東輿) seemed to be made between 1859 and 1866 but it was ahead of Cheonggudo(靑邱圖) in terms of the content and format. Accordingly he insisted that Cheonggudo was compiled based on the original version of Dongyeo which was supposed to be drawn between 1790 and 1834. This paper reappraised critically the previous researches and got several findings. Firstly, the changes of place names-4 places names were selected for the Jang Sang-Hoon's research and 2 were added in this paper-are reflected in the Yeodobiji(輿圖備志) and Dongyeo compiled by Choi Seonghwan(최성환) and Kim Jeongho(金正浩) between 1853 and 1856. Secondly, the sectioning format of Dongye shows some transitional character from the book style such as Cheonggudo to the folding style that was shown in Dongyeodo(東輿圖) and Daedongyeojido(大東輿地圖). Thirdly, the expression of the mountains in Dongyeo shares the same style which is shown in Dongyeodo and Daedongyejido. Fourth, Dongyeo contains the same information about old military bases and the castle locations in small local town centers that appear in Dongyeodo and Daedongyeojido but not in Cheonggudo and similar kinds of maps. In conclusion, Dongyeo and the original version of it are likely to be drawn by Kim Jeongho between 1853 and 1856 after Cheonggudo was made.
