According to cultural characteristics, Jung-Won cultural region are divided 10 sub-regions. These regions must be highlighted cultural image as core symbols and created new and regional culture to differentiate development strategy of cultural resources: (1) Chungju: historical and cultural region(stone pagoda of Tap-Pungri), (2) Zechun: cultural region of the righteous soldiers (captain Yu, In-Suk), (3) Dunyang: cultural region of Gogurue(mountain castle of On-Dal), (4) Chongju: educational and cultural region(Zikzi and Chull Dandgan), (5) Boeun: cultural region of buddhism(Bupzoo temple,) (6) Okchun: cultural region of Silla and Bakje(war of Silla and Bakje), (7) Yongdong: cultural region of three provinces(harmony monument stone of Samdobong), (8) Eunsung: cultural region of scholar spirit(Monument of 6. 25 war), (9) Goessan: cultural legion of cofucianism(confucianist Song, Shi-Reull), (10) Zinchun: cultural region of Sam-Guk unification spirit (general Kim, You-Shin).
This study was to look into the press policy and the related activities performed by North Korea in the South during the Korean War and to evaluate them. In order to understand the concrete contents of the activities and their characteristics, the two representative newspapers published in the South by North Korea at that times - the Chosuninmin Bo and the Haebang Ilbo - were reviewed and analyzed. North Korea operated broadcasting and started newspapers just after the possession of Seoul. and also performed various positive press activities - such as the distribution of the newspapers and periodicals of North Korea and U.S.S.R., putting the movies on the screen, and founding the weekly, etc. But the target of all the media were the same. It aimed to support Kim Il-Sung's scheme which intended to carry out the war successfully and to make the South under occupation Communism System by introducing the Northern law and system. The two newspapers, as agent of power, made only such a role to agitate and exaggerate the false things with unrealistic optimism. They intended to ideologically mobilize the South people and to affect on their perspectives and acts. However the media including the two newspapers being operated in the South during the war had not got the faith or the good response from the South people as an audience. Most of South Koreans were tired with their endless and one-sided propaganda, agitation and ideological enlightenment. It could therefore be evaluated that the press activities by North Korea in the South during the Korean War resulted with many limitations in ideologically organizing and mobilizing the South Koreans.
This study investigated a graded-refractive-index (GRIN) coating pattern capable of improving the light extraction efficiency of GaN light-emitting diodes (LEDs). The planar LEDs had total internal reflection thanks to the large difference in refractive index between the LED semiconductor and the surrounding medium (air). The main goal of this paper was to reduce the trapped light inside the LED by controlling the refractive index using various compositions of (TiO2)x(SiO2)1-x in GRIN LEDs consisting of five dielectric layers. Several types of multilayer LEDs were simulated and it was determined the transmittance value of the LEDs with many layers was greater than the LEDs with less layers. Then, the specific ranges of incident angles of the individual layers which depend on the refractive index were evaluated. According to theoretical calculations, the light extraction efficiency (LEE) of the five-layer GRIN is 25.29 %, 28.54 % and 30.22 %, respectively. Consequently, the five-layer GRIN LEDs patterned enhancement outcome LEE over the reference planar LEDs. The results suggest the increased light extraction efficiency is related to the loss of Fresnel transmission and the release of the light mode trapped inside the LED chip by the graded-refractive-index.
The formation of early korean scientific community is a dynamic process of korean modern history in which colonialization, liberation, United States Army Military Government and Korean War is included. Particularly, scientist's crossing over the border into north korea and south korea have profound effect on the early stage of our scientific community. This period is so important to understand the nature of korean scientific community that we need to re-interpret the role of 'ideology' in the development of scientific community. On the other hand, war is a important element in our formation of the image of the science. This study purported to interpret the problem of political ideology, it's role in the formation of early scientific society, it's implication on our idea of science positively. Also the study is a an attempt to re-construct the scientist's struggle(1945-1950) to demarcate new science from old, colonial science.

This study is a spatial analysis of the boundaries related to the division of the Korean peninsula. The boundary space was extracted by extracting $38^{th}$ parallel and digitizing the map of the Armistice Agreement Annex. The purpose of this analysis was to extract more accurate scope based on the armistice agreement, the appendices, and the UNC regulations and to analyze the wrong information correctly. The range of demilitarized zones was determined by UNC 551-4(2014) and UNC 551-5(2015) to ensure that there is no change in the location of the Southern Limit Line. It also confirmed that the MACHA was excluded in the DMZ. As a result, the area of the DMZ was measured at $889.7km^2$. Also this study identified the interval and number of markers in the MDL and the Han River estuary. It could be confirmed that the interval of markers within the MDL depends on the subject of management. This study is more accurate from the start and can be used as basic data needed in the study and education of DMZ and border areas after verification by public organizations.

The boundaries of ROK maritime jurisdictional area remains unclear as two Koreas failed to draw clear maritime boundaries at the armistice agreement and there are no clear maritime boundaries with China and Japan. After the Korean War, the United Nations Command established the northern limit line(NLL) as well as the area of operations(AO) to enforce the DPRK's compliance with the armistice agreement and has been controlling all of the maritime and air activities in the region. ROK also has been controlling the passage of DPRK vessels in the area. Within the AO, third nation vessels have freedom of navigation, Yet, due to the division followed by the Korean War, ROK classifies DPRK as a hostile state and unique controling system is applied to DPRK vessels. Since the establishment of the AO, many changes have been occurring such as adoption of the UN Convention on the Law of the Sea(UNCLOS) and two Koreas' joining the UN. Also, there are continuous inter-Korean conflicts. Therefore, the geographical span of the AO needs to be reconsidered. Furthermore, a legal measure which ensures ROKN vessel's functional capability of controling DPRK vessels must be introduced. This thesis examines post-Korean War DPRK vessel control system in the Korean peninsula as well as how it should be improved.
This study references preceding studies to examine the history of paint application techniques using various paints in the past, with the aim to contribute to the long-term preservation of large military cultural heritage assets situated outdoors. To this end, the study compared the findings of preceding research with the findings of an analysis conducted on a H-13 helicopter housed at the War Memorial of Korea. Upon collecting and analyzing samples from three grounded WWII aircraft from above-ground by preceding studies, it was confirmed from each sample that the various chemical properties of chrome ensured the effectiveness of the protective coating. The compound was first tested as a corrosion-inhibiting pigment in the early 1940s and proved its excellent moisture-resistant properties over the course of 80 years, despite the deterioration of the paint layer and long-term exposure to the natural environment. For this reason, it has been widely used as a corrosion inhibitor for aluminum alloys in the aviation industry. In other word, the most widely-used material for preventing corrosion was an organic primer containing chromate. In this study, based on the paint analysis of a H-13 helicopter operated in the Korean War, it was shown that the second layer, consisting of the primer, contains chromium oxide (Cr2O3). In addition, it was estimated that red lead tetraoxide (Pb3O4) was used for the vehicle. Analysis results and data from previous studies can help to confirm the continued effectiveness of corrosion prevention function provided by chromate. Meanwhile, the result of infrared spectroscopy analysis confirmed the use of alkyd resin. In the future, comparisons with a more diverse range of artifacts will allow the identification of changes in the manufacturing technology of paints used to protect alloys from corrosion.
The $76^{th}$ National Treasure is consisted of seven volumes of Nanjung Ilgi (War Diary of Admiral Yi Sun-sin; each titled by the author based on the zodiac name of the year covered, i.e. Imjin Ilgi, Gyesa Ilgi, Gabo Ilgi, Byeongsin Ilgi, Jeongyu Ilgi, Sok Jeongyu Ilgi, Musul Ilgi), Seogancheob (Letters of Admiral Yi) and Imjin Jangcho (Drafts of Imjin War Reports of Admiral Yi). These are currently in the custody of Hyeonchungsa shrine, the state-managed memorial shrine of Admiral Yi, and has been added to UNESCO's Memory of the World Register in June 2013 in the appreciation of its historical and academic importance as a commander's hand-written battlefield accounts during Japanese invasions of Korea. Imjin Jangcho, among these nine volumes, is a record of battles, including observations on the enemy fleets, suggestions on naval matters, battle expenditure, and methods of battle preparation, transcribed by someone else according to Admiral Yi's instructions. It is Admiral Yi's honest detailobservations on the war situation during Japanese invasions of Korea from 1592 as a Naval Commander of Left Jeolla Province, till 1594 (Year 27 of King Seonjo's reign) as a Commander-in-Chief of the Naval Forces of the South. It is a draft of the war report to be submitted to the King in a single volume as a folio (each sheet folded once to produce one leaf) bound in a side-stitched binding with five holes and inner binding of twisted paper. This study explores the condition and the treatment performed on Imjin Jangcho which could have an implication for the conservation of cultural assets on paper of late Joseon Dynasty.
This thesis looks into the interpretation of the Korean War and mystery genre in Korea in the 1970s by analyzing the special drama , in which the theme was directly related to the Korean War, airing through MBC in 1979. It begins by finding the change in direction in the 1970s when the world of TV was dictated through the heavy censorship and the memory of the war by the government. It also looks at the intentions of the producer who was taking in the new way and the viewers who also accepted this drama and its reflections. In order to gain some insights into these issues, it compares between the drama "The Last Witness" and the original novel by Seong-jong Kim who holds the same time to see the way in which this is dramatized. The drama, "The Last Witness", was produced with a plan to generate a high-quality special drama which combined both artistry and sense of purpose. Nevertheless, as watching TV became a leisurely past-time during this period, TV dramas become more aggressive and suggestive in order to attract viewers. This ultimately was encored with obstacles due to the regime and the heavy censorship at the time. The genre of special drama that is well known in South Korea, is designed as an art form to satisfy both their unique artistry and its purpose. The conflict is seen between the key elements of the artistic drama crated by the producers and the 'encouraged' elements that often are needed to engage the viewers. Thus, more often than not, special dramas defeat the original intention of national harmony, encouraged by the regime. This is due to the 'novelty' aspect which grows from the effort of bringing enjoyment to viewers whilst also trying to achieve the artistic drama to life. Alongside this, crime element in this drama is designed in a way that visually embodies the process of deduction, becoming a new possibility to secure the reality of the times. However, it was also a paradoxical existence since it was indicated as an example of unrefined culture that lost its original intention. In that way, it is worth to think that detective suspense stories, which were not popular in Korea, influenced viewers as a tv drama series in the 1970s through the various elements that compose the genre. They went through a process of transplantation and acceptance whilst also attempting to satisfy the viewers and their encouraged elements to engage them. As is well known, crime drama in Korea has its own style by mixing anticommunism and detective reasoning. This combination is found in the way in which the genre naturally forms through the elements selected and excluded in the dramatization of "The Last Witness". The point is that the special drama "The Last Witness" can be seen as an intermediate form that shows the tendency of transformation from the detective reasoning form alongside the crime aspects as TV dramas began to include anticommunism messaging and investigation in the 1970s. In conclusion, when the detective reasoning is used as an element in a TV drama, it shows the trust of the public system and it constantly seeks the possibility of circumventing the political interpretation. The memories of the war is seen as a tool that neutralizes the dismal imaginations inscribed on the dark side of society and the system. As a result, "The Last Witness", broadcasted at the end of the Yushin regime in Korea, is a strange result which combines the logic of a special drama and the encouraged characteristics of television dramas. The viewers' desire which is the discussion about the hidden traces from the texts needs to be restored again.

The weapons excavated from the de-militarized zones (DMZ) of Korea are vulnerable to corrosion due to the immediate and drastic environmental change. Especially, the chloride ions (Cl-) in iron weapons cause active corrosion and require removal. In this study, conservation treatment and de-salination was performed for the discovered weapons from excavation sites of soldiers killed in action during the Korean War. Furthermore, an attempt was made to prepare the most stable plan for conservation treatment through the comparative study of soaking weapons in distilled water without chemicals and in a solution of sodium (SSC) at different temperatures. In the preliminarily experiments, the comparison of the eluted Cl- ions according to different conditions of de-salination showed that the highest number of ions were detected from the de-salination with SSC at a temperature of 100℃, and its duration was much smaller, i.e., 1~2 weeks. Accordingly, for the parts from the guns and rifles amongst other objects, a six-time de-salination was conducted in the SSC solution for 8 hours at 100℃ and subsequently, for 16 hours at room temperature during which the distilled water and SSC were exchanged every week. However, in the case of a loaded rifle, the de-salination was not conducted, considering the risk that the high temperature and pressure by impregnation in vacuum could cause an explosion
