This study examined the construction method shown in literatures and materials discovered in rampart, barbican and guard platform for Cheongdo-Eupseong castle which was constructed immediately before Japanese Invasions of Korea (1592-98). According to the result of the examination, the construction method used in the coastal areas and inland areas of Gyeongsang province in the early Joseon period was applied to the rampart, barbican and guard platform in the east and north castle walls, which was constructed earlier than other parts of Cheongdo-Eupseong castle. However, from the western end of the northern castle wall, which was later constructed, to the western castle wall was rebuilt using a construction method different from the method applied to the parts that were constructed earlier after Japanese Invasions of Korea. Cheongdo-Eupseong castle was constructed on a flatland on a large scale and at a low height under unreasonable pressures to construct the castle in a short period of time for military defense as well as civil agitation in the imminent situation just before the outbreak of Japanese Invasions of Korea. In addition, various methods of constructing Eupseong castle utilized at that time were used together, and barbican and guard platform were built generally focusing on rapid completion and convenience, using other methods than the one mainly used at that time. This is the reason why there was a difference in the characteristics of the method and period of castle construction between Cheongdo-Eupseong castle and other Eupseong castles in the coastal areas and inland areas of Gyeongsang province.

Periodically, the Japanese Castle was created in the domestic of Japan and then 2 Invasions into Chosun was started. The Japanese Castle in the domestic of Japan was repaired several times by the building boom of castle before & after 2 invasions and so the initially-built type of castles was changed. Accordingly, there are much difficulties to understand the original shape of Japanese Castle. Through the Japanese Castle within Korea called as the fossil of Japanese Castle, I would like to examine & consider its building period and characteristics. The terminology called as [Two Side Stone's Wall] is that of castle which is not acknowledged in the Japanese Academic Circles. However, it means the two-fold wall of Japanese Castle which was widely applied to the fortification way in the Age of Japan Edo. The terminology of [Sori] says the stonework curve in the corner of Japanese Castle which is indicated best in the Japanese Castle. It calls the curve as like the fan frame. [Curb Stone's Wall] says the type of castle wall constructed with over 1 face in wall body of Japanese Castle. (1) About classifying the construction period of Japanese Castle, the curb stone's wall and the castle having no two side stone's wall must consider the building period as that of Japanese Invasion of Korea in 1592. If there was [Sori], the two-side stone's wall was used and the place which supported the documentary data, in particular, the place having the record of contraction is considered to be confirmed as the castle constructed in the period of Japanese Invasion of Korea in 1597. (2) The two-side-type stone's wall shown in the Modern Japanese Stone Castle is difficultly considered to be generated from the Japanese Castle at the period of Japanese Invasion of Korea in 1592 and in 1597. (3) The beautiful [Sori] shown in the Modern Japanese Stone Castle was started from the Japanese Castle of Korea at the period of Japanese Invasion of Korea in 1597. It is difficultly considered which its indication was firstly generated by the Chaesung-Folded Segment Structure.

In information retrieval process through search engine, some users want to retrieve several documents that are corresponding with specific time period situation. For example, if user wants to search a document that contains the situation before 'Japanese invasions of Korea era', he may use the keyword 'Japanese invasions of Korea' by using searching query. Then, search engine gives all of documents about 'Japanese invasions of Korea' disregarding time period in order. It makes user to do an additional work. In addition, a large percentage of cases which is related to historical documents have different time period between generation date of a document and record time of contents. If time period in document contents can be extracted, it may facilitate effective information for retrieval and various applications. Consequently, we pursue a research extracting time period of Joseon era's historical documents by using historic literature for Joseon era in order to deduct the time period corresponding with document content in this paper. We define historical objects based on historic literature that was collected from web and confirm a possibility of extracting time period of web document by machine learning techniques. In addition to the machine learning techniques, we propose and apply the similarity filtering based on the comparison between the historical objects. Finally, we'll evaluate the result of temporal indexing accuracy and improvement.

This is the paper on the descriptive perspective and writing method in Yeheon(旅軒)'s Piranrok(避亂錄). Piranrok was Yeheon's diary which was written during Japanese invasions of Korea. Many intellectual recorded their diaries during the war. Yeheon's Piranrok was a typical example among war journals. I tried to take view of the descriptive perspective and writing method in Yeheon's Piranrok. First, sourceful introspection was distinct characteristic in the descriptive perspective. Yeheon penetrated into a chaotic state of affairs during Japanese invasions of Korea. And Yeheon had reflective consciousness about self-existence. He contemplated his existence through diary writing. I had a task to study the writing methods in Yeheon's diary. One of the distinct characteristic in writing methods was to increase specific gravity of discussion. Yeheon advocated strongly his opinion and position about cause of war, war responsibility, morality, fortification and righteous army. Yeheon made the best use of communication method and catechetic method. He answered his own questions about the enter and retirement of public office. He expressed his worry and conflict through various techniques of expression. I have a task to study the diary in Chosun dynasty. I believe that analyzing characteristics of Yeheon's diary can contribute to understanding the literature history of diaries in Chosun dynasty.

The purpose of this paper look at the basis of the cultural differences of Korean and Japan by comparing the craftsmanship. Korean craftsmanship and master craftsman making traditional handcrafts and artwork would die out at a critical moment. The craftsmanship and system could not be established because of discrimination in the traditional four classes of society( scholars, farmers, artisans and tradesmen), invasions of other countries and discontinuity of tradition from modernization. On the contrast, in Japan, it was possible to establish traditional handcrafts and artworks, technique and craftsmanship with apprentice system and various social privilege and treatment even in the same traditional four classes of society ( scholars, farmers, artisans and tradesmen). It was common to pass down the family business for a hundreds of years with self respect between Japanese master craftsmen and lots of people succeed the family business will now. Japanese craftsmanship is originated from 'worship to god' Medieval Japanese believed that the thing changes human mind, artistic talent, masterpieces and faith were connected to sacred power. Therefore, master craftsmen and their works were also made by the power of god. In this context, craftsmen were protected and treated in socially and nationally. It is that the social treatments and supports in national level and their own pride and continuous training of techniques and abilities as the main driving force to maintain the craftsmanship in Japan. Korea has the sale level of competitive tradition and technique in comparison any other countries. Japanese craftsmanship study will be a critical data in the protection and maintenance of Korean traditional and technique.

This study explored the concept and use of two kinds of textiles goods (Cheongpo [blue textile] and Samseung) sold by Cheongpo-jeon merchants in the Joseon Dynasty of Korea. Research was conducted based on an analysis of relevant documents published during the Joseon Dynasty. The Cheongpo-jeon was a merchant group that predated 1637. They sold various imported goods such as Cheongpo, Samseung, cotton textiles, felts, hats, incense, and needles. Cheongpo and Samseung were the main products among these imported goods. Cheongpo was a blue cotton textile imported from China that was sold by Chengpo-jeon merchants. The Samseung sold by merchants was a kind of imported textile whose surface provided a feeling like cotton flannel. The concept of the two textiles were different from existing ideas. Generally, the Cheongpo was believed to be a hemp fabric dyed in blue and the Samseung was a textile with a density of three seung (a traditional density unit of textiles). Cheongpo was used as a currency for war supplies during the two Japanese invasions of Korea (1592 to 1598). In addition, it was also used to make military uniforms, tents, and flags after the Japanese invasion. Samseung was used in the combat uniforms of Chinese soldiers from Ming China during the Japanese invasion of Korea. In addition, it was continuously used to make quilted gambeson amour and some of military uniforms until the $19^{th}$ century.

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.

Since Korea and Japan established diplomatic relationship, Relationship between Korea and Japan has not been easygoing. There are two most explosive, and noticeable ones among topics which have affected the relationship ; Dokdo and Historical Distortion. Without these issues, relationship between two countries will take a turn for the better. However, unfortunately, it seems that it is almost never going to happen. There is the Japanese conservative right-wing who has an influence on those two issues. The right-wing takes regard getting negative view or finding out dark past as an action from Self-torture view of history, and tries to dilute the Japanese sense of guilt on past invasions to neighbor countries. Moreover, to become a "normal country", they are trying to revise Constitution of the Japan so that Japan can possess the military and re-arm, dispatch troops abroad, and get the right to break the war. In other words, they expect Japan to become a powerful nation with great influence on Asia and world, as the period in which Japan conquered Korean peninsula, China, and South-Eastern nations. Japan still harbours secret romanticism for bygone days of imperialist glory. That is why neighbors want to never make the painful history happen again. In order to deal with this effort, most of all, it is required to assert better argument with a careful, thorough analysis on Japanese opinion about Dokdo. There might be a hidden card which can be accepted in the international society considering Japanese persistent effort to make Dokdo disputed area, and that is why we have to know that it is. In addition, it is needed to secure a high-quality professional manpower because the issues of Dokdo and Historical Distortion are primarily the matter of logic and references. The professional manpower should have open-minded to break down walls of their own majors. We have to introduce our achievements and stances to the international society vigorously. As a definite way to solve these problems, we have to develop national power. We have to possess naval forces and coast guard to protect our territory and Koreans overseas. There are not many options Korea can do to Japan, except protesting denunciation, and pressing a joint efforts. Most of the suggestions stated before are what have to be conducted domestically. It is a miserable condition, because two problems are Japanese domestic issues, but they become international issues and we have to seek a solution for ourselves.

We study the correlation between distributions of astronomical records and historical events using historical meteor (shower) records. In Korean chronicles, planets and meteor (shower) records are the most abundant astronomical phenomena. And they represent a general tendency of the number distribution of whole astronomical observations. We examine the correlation for the number distribution between meteors (showers) and planets during A.D. 1200-1700 and find that both records have a similar distribution. We classify historical events into three grades according to the social impact, and investigate the correlation between distributions of meteor (shower) records with social events, such as, new king's accession to the throne, foreign invasions, and domestic turmoils. From the statistical analysis, we cannot find any correlation between the meteor (shower) records and the political events. Therefore, we conclude that Korean historical records have not been influenced by the political events. We also examine the correlation between Chinese and Japanese meteor (shower) records and political events for A.D. 1200-1700, respectively, but cannot find any correlations between them.

The purpose of this paper is to review the representative Buddhist policies enforced during the reign of Gwanghaegun (光海君), the 15th king of the Joseon Dynasty, and the aspects of the Buddhist community affected by them. Through this, the influence and dynamism of Buddhism during the reign of Gwanghaegun will be revealed. Some of the findings will run contrary to what is popularly known about Joseon Buddhism and the policy of Sungyueokbul (崇儒抑佛), 'Revering Confucianism and Supressing Buddhism.' During the Joseon Dynasty, Neo-Confucianism was taken as an ideological background, and consequently, Buddhism was ostracized by the ruling class who advocated the exclusion of heretical views. This also characterized King Gwanghaegun's reign during the Mid-Joseon Dynasty. In reality though, the ruling class held mixed opinions about Buddhism, and this influenced the Buddhist community in the Gwanghaegun Period. The military might of Japan demonstrated during the Japanese Invasion of Korea in 1592, led the ruling class to recognize Buddhism, and as a result, the status of Buddhism rose to a certain extent. Based on its elevated status and the aftermath of the Japanese Invasion of Korea, the Buddhist community engaged in social welfare activities inspired by the notion of requiting favors, and the Buddhist community gained recognition for providing relief services. As a result, the number of monks increased, and the economic situation improved as land ownership was granted to temples and monks. This is the means by which the Japanese Invasion of Korea influenced the Buddhist policies of the Gwanghaegun Period and changed the religious topography of Buddhism. During the reign of King Gwanghaegun, the ruling class regarded Buddhism as heretical, but offered posthumous titles to monks who engaged in meritorious services during the Japanese invasions of 1592~1598. Favorable and/or preferential treatment was also granted to some Buddhist monks. In addition, monks began to perform labor projects that demanded organizational and physical strength, such as those which related to national defense and architecture. However, throughout the Gwanghaegun Period, the monks were paid a certain amount of compensation for their labor, and the monks' responsibility for labor increased. This can be understood as a partial reconciliation with Buddhism or an acceptance of Buddhism rather than the suppression of Buddhism often presented by historians. As for policies which affected Buddhism, the Buddhist community showed signs of cooperation with the ruling class, the creation and reconstruction of temples, and the production of Buddhist art. Through close ties with the ruling class, Buddhism during the Gwanghaegun Period saw the Buddhist community actively responded policies that impacted Buddhism, and this allowed their religious orders to be maintained. In this way, it was also confirmed that the monk, Buhyu Seonsu (浮休 善修) and his disciple Byeogam Gakseong (碧巖 覺性), took up leadership roles in their Buddhist community. The Buddhist-aimed policies of Gwanghaegun were implemented against the backdrop of the Buddhist community, wherein the ruling class held mixed opinions regarding Buddhism. As such, both improvements and set backs for Buddhism could be observed during that time period. The ruling class actively utilized the organizational power of Buddhism for national defense and civil engineering after the Japanese invasions of 1592~1598. Out of gratitude, they implemented appropriate compensation for the Buddhists involved. The Buddhist community also responded to policies that affected them through exchanges with the ruling class. They succeeded in securing funds and support to repair and produce Buddhist temples and artworks. A thoughtful inspection of the policies towards and responses to Buddhism during the Gwanghaegun Period, shows that Buddhism actually enjoyed considerable organizational power and influence. This flies in the face of the general description of Joseon Buddhism as "Sungyueokbul (revering Confucianism and supressing Buddhism)."
