The HLA is the simulation architecture standard that the civilian and military simulation communities are deeply interested in. We can find various successful practices applying HLA to constructive simulations such as war games in domestics and overseas. However, any case of real-time distributed simulations has not been reported. The reason is that a message transmission period via RTI in a network layer varies according to computing power, simulation nodes, transmission types, and packet size; further a message processing time in an application layer depends on its processing methods, thus too difficult to set up real-time constraints for the enhancement of a real-time resolution. Hence, in this paper we have studied the real-time constraints of RTI for the development of the M-SAM simulator. Thus we have developed a HLA based pilot simulator using 6 PC's in LAN and then measured and analysed the performance of the RTI. As the results of our work, we could obtain the quantitative values for message delay, RTI overhead and RTI packet transmission ratio by a real operation scenario and loads, which are not shown in the previous works. We also expect that the results can be used as a guideline to set up the number of targets, transmission frequency and message processing method in the development of the M-SAM simulator and similar applications.

he guarding system of the "Choson" era is completed by the Gyeongguk-daejeon(an administrative canon) at the kings "Sejong" and "Yejong", and it is supplemented at the King "Seongjong". "Geum-gun" is composed of "Naegeum-wi", "Gyeombok-sa", "Wirim-wi" and "Jeongro-wi" in the period before the Japanese Aggression of Korea in 1952, and in the period after the aggression war, the organization of the "Geum-gun" is changed repeatedly according to circumstances in the period after the aggression. They("Geum-gun") devote themselves to the protection of kings and the capital defense in the first period of the "Choson" era. The most important change of the "Geum-gun" is the practice of five military units system, three military units of them, "Hunryeon-dogam", "Eoyeong-cheong" and "Geumwi-yeong", take charge of the guard of kings and the capital defense, and "Chongyung-cheong" and "Sueo-cheong" take charge of the defense of the outer areas of the capital region with key positions located at "Namhan-sanseong" and "Bukhan-sanseong"(mountain fortress Walls). The function of the "Geum-gun" is extended through the aggressions, therefore the number of soldiers is increased greatly. The guarding system for the country and its royal family is frequently changed according to the improvement of the people's position with themselves-awakening and their understanding of realities. The reorganization of the "Geum-gun" including "Howi-cheong", "Geumgun-cheong", "Sukwi-so" and "Jangyong-yeong" is unavoidable to strengthen the royal rights that are weaken by deposing the king "Injo". The standing of the existing organizations is changed many times with financial problems. The enthronement of the king "Jeongjo" is a great epoch in the change of the guarding system.

The late Professor Lee CB (1915~1967) was one of the pioneers in the early stages of thoracic surgery in Korea while he was in charge of the Department of Thoracic and Cardiovascular Surgery at Seoul National University hospital as the first director from 1957 until he died of liver cancer in 1967. He was a graduate from the old Seoul National University, and he dedicated himself to the field of lung surgery after he joined the army during the Korean War, which broke out in 1950. Among his many contributions to pulmonary surgery, he performed the first partial lung resection in Korea in 1953. His lecture notes were recently found. These lecture notes for medical students were written by hand in late 1950s, Considering the content and form of the lecture notes, they are thought to have very significant historical value. The lecture notes were a total of 277 pages on general thoracic surgery and cardiovascular surgery with 75 self-drawn figures. This study was intended to facilitate a better understanding of the history of thoracic surgery in Korea, and especially for young thoracic surgeons. These notes may well contribute to the field of Thoracic and Cardiovascular Surgery in Korea.

This study is for species identification for each structure member such as Pillar, Bo, Changbang, Dori, Jangyeo, Judu, Donjaju, Chunyeo, Guitle, and Jongdae, of Pungnammun Gate (Treasure 308). Jeonju is the birthplace of Joseon Dynasty and Pungnammun Gate was the southern gate of old Jeonjueupseong which was walled town. Provincial Governor of Koryeo Dynasty, Yu Gyeong Choi built Jeonjubuseong and four gates at all cardinal points in 1388. And the gate was burnt down by Jeongyujaeran (war with Japan in 1597). It was rebuilt by King Yeongjo (Joseon Dynasty) in 1734 and renamed 'Pungnammun' after 34 years. It was designated for Treasure 308 for its unique style of architecture and historic values in 1963. In this study, all of wooden structure members were Pinus spp.. This result was matched for the result of major species for wooden building of late Joseon Dynasty. It can be used to complete database for architecture of Castle's Gate and help for restoration of cultural heritage in the future.

Satae cheon, a tributary of the Suip cheon in Yanggu, Gangwon province, is an international river extended to North Korea. Most of drainage basin area of the river was the fierce battle field during the Korean War(1950-1953) and hard to access as it located between the MDL(Military Demarcation Line) and the CCZ(Civilian Control Zone: about 10km south from MDL). By the restriction of access to the sites, most of natural landscape have been well conserved except limited use for military activities. Even the landfoms in that area were not studied, except the government's heritage reports. Satae Cheon's channel follows the Imdang fault line(N-S) to Satae-ri and flow to west to the Dutayeon area. The river meanders along geological structure or weak line at the Dutayeon area. The meandering channel was shorten by the meander cut which linked the thalweg line of meander loop ant the meander neck. As a result of this cut, the river cliff formed by the Satae cheon became the part of newly formed channel bed and the S-forms are formed. After the channel route stabilized, channel incised the rock with large potholes and undulating walls were formed. The channel width changes from 1m to 10m with restriction of the undulating walls, so this part can be regarded as inner channel or inner gorge. From the point of planar forms it also can be slot-type canyon.

This article criticizes the dichotomous world view in which the East and the West are absolutely divided from each other and asserts that the East and the West should be understood as 'we' who ought to acknowledge each other not only as subjects but also reciprocally as 'others'. If the East is 'I', then the West is 'You' and vice versa and as such, the East differs from the West. Hence, supposing that they both regard themselves as subjects and if they realize that they can also be others against the other subject, they as different subjects should be understood as 'others in us'. Since the 19th Century the East has made efforts to learn and accept Western culture and thought. But it seems that the East has never regarded the West as an 'other in us', but rather as either an 'other outside of us' or as 'the real I that it should develop into'. This shows the self-contradictory perspective of the East. It can be thought that such an attitude was revealed as typical of the Far East in the 19th Century, in which the Opium War broke out and Sinocentrism collapsed. On the other hand, the West has never recognized the Eastasan 'other in us'. Nowadays we pursue the most actual value, that is, 'globalization'. In order to realize that value for the development of the whole human, it is necessary that both the East and West should first recognize each other as the 'other in us'.

After World War II, modular housing was developed as a means of quickly and efficiently meeting the housing supply demand. For the past 30 plus years, efforts have been made to improve modular housing in South Korea and to increase their competitiveness in the housing market. This study investigated modular houses based on a steel framed rahem structure which provides a flexible floor plan where walls are easily reconfigured to create rooms of various sizes and functions. Similar to the factory production methods used in the automotive industry, the modular housing industry can also benefit by standardizing such aspects as building components, manufacturing and construction methods, materials, process management, and floor plans. This study examined the feasibility of using a 3m × 3m module for developing various floor plans which are easy to produce and transport. Each 3m × 3m module can be configured to meet different living needs resulting in a complete home when multiple modules are connected. The module configurations can be varied to meet ground transportation and crane limitations. This study found that a 3m × 3m steel framed modular unit is a promising step towards providing residents with plans that meet their living preferences while improving and increasing the supply of modular houses.

Gwanghwamun Gate of Gyeongbokgung Palace was dismantled and relocated during the Japanese colonial period, destroyed during the Korean War, reconstructed with reinforced concrete in 1968, and finally erected at its present location in 2010. A pair of Haechi statues located in front of Gwanghwamun was dismantled and relocated several times, and the statues have yet to be returned precisely to their original positions. This study assesses the historical accuracy of their current placement under the Gwanghwamun Square Restructuring Project of the Seoul Metropolitan Government and the Cultural Heritage Administration based on archival photos from the early 1900s, and proposes a method to estimate the original positions of the Haechi through image analysis of contemporary photographs and recent digital camera photos. We estimated the original position of the Haechi before the Japanese colonial period by identifying the shooting location of the archival photo and reproducing contemporary photographs by calculating the angle and distance to the Haechi from the shooting location. The leftmost and rightmost Haechi were originally located about 9.6 m to the east and 7.4 m to the north and about 1.9 m to the west and 8.0 m to the north, respectively, of their current location indicators. As the first attempt to determine the original location of a building and its accessories using archival photos, this study launches a new scientific methodology for the restoration of cultural properties.

The purpose of this study is to trace the path of policy for urban parks and greenbelts (PUPG) pursued by Seoul Mayor Kim Hyeon-ok, who was a protagonist of Seoul's modernization and to reveal the policy's characteristics. A high modernism perspective was projected to advance his PUPG discussion. High modernism was an unavoidable phenomenon that appeared in post-war urban reconstruction projects and emerged in the form of a belief that the national elite creates the ideal social order and rational planning. Its characteristics were to build with legibility, immediacy, and convenience by power, with private participation and profit creation, while realizing the spectacle of "the city being built". As a high-modernist, Seoul Mayor Kim Hyun-ok's urban planning aimed to deal with the booming population and the expansion of Seoul's territory. Although his PUPG extended the parks to the outskirts of Seoul, he showed a dualistic attitude, diverting parks away from the city center. On the other hand, he induced the participation of the private sector to create parks. However, he showed the other side of modernization, eliminating the placeness and excluding related systems. The path taken by Mayor Kim Hyun-ok's PUPG was started to respond to population growth and resolve the encroachment of parks. The ultimate goal was to accept the realization of urban planning and experiment with non-financial methods. The characteristics of his PUPG reflecting high modernism were: First, elites were represented in the National Land Planning Association, HURPI, and Jang Moon-gi participated; second, legibility was ensured by using east-west and north-south axes, elevation standards, and rational planning. Third, parks were quickly released to respond to the rapid urban change. Fourth, it showed off events and spectacles to attract private capital.

In Europe, the diversity in religions, cultures, languages and historical backgrounds is enormous. World War II and the Soviet Regime have played a large part in this and the flow of refugees from other continents increases the pluralism. How can religious education add to bridging between differences? The language across European countries is different, literally between countries, but also figuratively speaking and even inside individual countries. These differences occur in cultural sense and across age groups as well. Secondary education has the task to form young people to become firmly rooted people who can hold their own in society. It is essential that they learn to examine their own core values and their roots. Recognising their values should be a main focus of religious education. However, schools are currently accommodating increasing numbers of non-religious pupils. What role do religious values still play in this situation? How do pupils feel about active involvement in religious institutions, and about basing life choices on religious beliefs? Can other, non-religious values be detected which could form the basis for value-oriented personal formation? Research of these subjects has been ongoing in the Netherlands for more than twenty years and is currently being expanded to the Czech Republic and(former East) Germany. These are also secularized countries but have a very different history. Does the history and context of these countries play a role, and does this show in the values that are important to pupils? A comparative pilot study is being conducted as start of this broadening perspective geared towards greater insight into the values of pupils in these three European countries. This information helps to design appropriate new forms of religious value-oriented worldview education.
