After the Korean war, two major attempts were made to reconstruct Gwanghwamun Gate as an important part of Korea's lost cultural heritage. In December 2006, the Korean government replaced the concrete gate with a wooden one, yet traces of the attempts made in the 1960s to transform Gwanghwamun Gate and the main road remain to this day. At the time, the Third Republic of Korea, sought to legitimize itself in the name of modernity, and went on to modernize the architecture and urban landscape of Seoul. The location and design selected for the rebuilt Gwanghwamun illustrated the symbolic relationship between historic heritage and urban development. The reconstruction of the gate began as part of the Third Republic's project to restore the Central Administration Building and culminated in the transformation of the main road in front of the gate. By reconstructing the traditional gate using concrete, the military government intended to convey the message that we could inherit our proud tradition using modern materials, and that we should actively adopt the new technologies of the modern era. This study begins with the premise that the Gwanghwamun reconstruction project of 1968 represents the application of new technological thinking to Korea's architectural style, and has two objectives. The first is to summarize the reconstruction process and method using the records and drawings from the 1968 project, which was then under the leadership of architect Kang Bong-jin. The second is to analyze the characteristics of the architectural style and structure of the reconstructed Gwanghwamun so as to reinterpret the relationship between Korean tradition and modern technology.

Objectives : High-normal blood pressure' is a factor influencing decision to initiate targeted intensive intervention strategy in westernized populations. JNC-VI offered the vigorous lifestyle modification for persons with 'high-normal blood pressure', who could be early detected. As a hypertension seems to be the result of multiple genetic factors operating in concert with associated environmental factors, it will be necessary to identify the high-normal blood pressure as a risk factor of hypertension for applying primary prevention strategy in Korean people. Methods : Although cohort study design might be adequate to recruit incidence cases, to keep time sequence of events, and to prevent information bias, nested case-control study was chosen for avoiding measurement errors because hypertension is a benign disease. Source population was the 'Seoul Cohort' participants and follow-up was done by using Korea Medical Insurance Corporation's database on the utilization of health services from 1 Jan93 to 30Jun97. Incidence cases were ascertained through the chart review, telephone contacts, and direct blood pressure measurements. Controls included the pairing of 4 individuals to each case on the basis of age. Results : As 75% of 247 incident cases had high-normal blood pressure, the crude odds ratio for hypertension was 2.04 (95% CI 1.47-2.83). Another statistically significant risk factors of hypertension were body mass index, dietary fiber, alcohol consumption, weekly activity and history of quitting smoking. The multivariate odds ratio of high-normal blood pressure adjusted for all risk factors was 1.84 (95% CI 1.31-2.56). Among high-normal blood pressure group, body mass index, weekly ethanol amounts, weekly physical activity, and dietary fiber except history of quitting smoking were still risk factors of hypertension. Conclusion : 'High-normal blood pressure' is a risk factor for hypertension in Korean middle-aged men, which represents that the vigorous lifestyle modification for persons with 'high-normal blood pressure' is need.

Even though the United States and Australia have a relatively short history, the preservation and reuse of their historical heritage and cultural heritage are considered to be very important. In the case of Korea, which has a long historical heritage, there is a lack of development and restoration systems and there are no clear guidelines on how to preserve and reuse these precious legacies. In this study, we examine and analyze through examples how the historic buildings have been preserved and reused in Australia and the United States, which have a shorter history than our own. Also, we suggest that the raising of awareness of the historicity associated with the existing architecture and that of the architectural environment following its full-scale reconstruction will enable them be considered historical heritages with the passing of time.

While going into troops for writing in the vignette style(小品文) in opposition to the Classical Chinese(古文), Yi Ok stopped by Songgwangsa Temple in Wanju. The things he felt during this stop were recorded in the Temple Chapter("寺觀") written in 1795. Therefore, the present dissertation evaluates the Songgwangsa Temple of the time based on this Temple Chapter. Data in the Temple Chapter draws attention to the fact that it records the layout of the temple in detail. Thus the study was able to confirm the change in layout by reviewing relevant records about repair. This reveals that the form of layout in general has been maintained although there were changes involving the relocation of the buildings and their names. Furthermore, the original Buddhist building was changed to a quarter for the monks. Also, in terms of layout after the 18th century, there are frequent name changes of the Myeongbujeon(冥府殿) and Nahanjeon(羅漢殿). After two repairs, in order to find the appearance of a Daeungjeon(Main Buddhist hall) with a two-storied structure of five bays at the front, the study evaluated the Geugnakjeon at Muryangsa Temple and the Daeungbojeon at Magoksa Temple. The evaluation revealed that the 'Jeol' used in the Temple Chapter were small pillars erected on a ridgepole just like the Geugnakjeon at Muryangsa Temple, and that the angle rafters were installed to corner bays in rectangular form. The intellectual Yi Ok left behind invaluable architectural data that reveals the Songgwangsa Temple of the 18th century.

This study is intended to analyze current status of costume in the cultural industry and explore feasibility of integrating costume as important cultural contents in the digital era. Among the websites for contents as the cultural archetypes, some have strong foundations while others don't. First, as for various archetypal characters restored based on the Korean history, most of their clothes focus on shapes and colors but lack details. They should be produced in 3D to provide back views or textile patterns to users. To ease understanding of the history of costume, user-friendly services such as launch of a pop-up window when users click on specific contents in question should be available for detailed information. At least there should be a link to other related sites where users can conveniently find more details. Second, some sites have too much data under one subject, increasing complexity and undermining orderliness. As a result, it takes long time to identify the site map. In this case, it is required to rearrange the contents with Quick View by subject and related links for in-depth study. Third, each subject is important to develop the archetypes for a variety of purposes. Creation of design derived from them or their commercialization can be an example but these activities should not restrict imagination of users or degrade the value of the archetypes. Last, it is needed to adopt validation system to detect the needs for a regular update (renewal) and to fix errors. We found many servers whose operation is not stable in general. When these technical issues are addressed for stable operation, users will rely on the sites to utilize them for their purpose of developing the cultural archetypes. In conclusion, advancement of www.culturecontent.com is essential. Based on efficient management and operation of the system, the quality of contents would be increased and multi-faceted advertising campaigns focusing on needs should be launched, to promote application of the contents. This is the recommendation for the future of the cultural archetype industry in Korea.

In the case of boiling on high temperature wall, vapor film covers fully or parcially the surface. This phenomenon, film boiling or transition boiling, is very important in the surface heat treatment of metal, design of cryogenic heat exchanger and emergency cooling of nuclear reactor. Mainly supposed hydraulic-thermal accidents in nuclear reactor are LCCA (Loss of Coolant Accident) and PCM (Power-Cooling Mismatch). Recently, world-wide studies on reflooding of high temperature rod bundles after the occurrence of the above accidents focus attention on wall temperature history and required time in transient cooling process, wall superheat at rewet point, heat flux-wall superheat relationship beyond the transition boiling region, and two-phase flow state near the surface. It is considered that the further systematical study in this field will be in need in spite of the previous results in ref. (2), (3), (4). The paper is the study about the fast transient cooling process following the wall temperature excursion under the CHF (Critical Heat Flux) condition in a forced convective subcooled boiling system. The test section is a vertically arranged concentric annulus of 800 mm long and 10 mm hydraulic diameter. The inner tube, SUS 304 of 400 mm long, 8 mm I.D, and 7 mm O.D., is heated uniformly by the low voltage AC power. The wall temperature measurements were performed at the axial distance from the inlet of the heating tube, z=390 mm. 6 chromel- alumel thermocouples of 76 .mu.m were press fitted to the inner surface of the heating tube periphery. To investigate the heat transfer characteristics during the fast transient cooling process, the outer surface (fluid side) temperature and the surface heat flux are computed from the measured inner surface temperature history by means of a numerical method for inverse problems of transient heat conduction. Present cooling (boiling) curve is sufficiently compared with the previous results.

This study is the consideration about Hwaryeong-Jeon that enshrines Joseon Dynasty 22nd king Jeongjo's portrait of a king. Suwon's Hwaryeong-Jeon that accompanied a portrait and performed ritual ceremonies had several formalities and ceremonies which are connected with rituals. therefore, we will try to examine what relation between arrangement of building and plane composition had. And through this, it is thing to observe construction special quality that Hwaryeong-Jeon has. Joseon Dynasty's young-jeon (a hall where the royal portraits are kept) is retaining each other different state according to construction age every moment. Hwaryeong-Jeon among Joseon Dynasty's a hall of royal portraits is the construction form which is equiped well and is known for keeping the form well from the foundation to now And this building is evaluated as the standard form of early part young-jeon building of 19th century. Especially, Hwaryeong-Jeon shows the typical ritual equipments late Joseon Dynasty and at the same time has all kinds of characteristics which only we can find at Hwaryeong-Jeon. Namely, Hwaryeong-Jeon is the building which brings the design concept of the hall of royal portraits to completion as the building which enshrines single portrait of a king. After all, Hwaryeong-Jeon is evaluated as the building which can pass excellent form of late Joseon Dynasty, the hall of royal portraits building just as it is. Therefore, as I study its own style, I expect Joseon Dynasty's mind that enshrined the portrait of a king elaborately to be revealed.

Methods for the seismic demands evaluation of structures require iterative procedures. Many studies dealt with the development of different inelastic spectra with the aim to simplify the evaluation of inelastic deformations and performance of structures. Recently, the concept of inelastic spectra has been adopted in the global scheme of the Performance-Based Seismic Design (PBSD) through Capacity-Spectrum Method (CSM). For instance, the Modal Pushover Analysis (MPA) has been proved to provide accurate results for inelastic buildings to a similar degree of accuracy than the Response Spectrum Analysis (RSA) in estimating peak response for elastic buildings. In this paper, a simplified nonlinear procedure for evaluation of the seismic demand of structures is proposed with its applicability to multi-degree-of-freedom (MDOF) systems. The basic concept is to write the equation of motion of (MDOF) system into series of normal modes based on an inelastic modal decomposition in terms of ductility factor. The accuracy of the proposed procedure is verified against the Nonlinear Time History Analysis (NL-THA) results and Uncoupled Modal Response History Analysis (UMRHA) of a 9-story steel building subjected to El-Centro 1940 (N/S) as a first application. The comparison shows that the new theoretical approach is capable to provide accurate peak response with those obtained when using the NL-THA analysis. After that, a simplified nonlinear spectral analysis is proposed and illustrated by examples in order to describe inelastic response spectra and to relate it to the capacity curve (Pushover curve) by a new parameter of control, called normalized yield strength coefficient (${\eta}$). In the second application, the proposed procedure is verified against the NL-THA analysis results of two buildings for 80 selected real ground motions.

Once, the faster the digital technology developed, the more provocative obscure commercial film has spread like a trend. Researching the aspect of the successful films, about 10 million audience in 2016, we can find the similarities that only social phenomenon, stands itself without real-existence, which makes public sentiment. I will list up all the problems that I mention above with audience's review and analyze the famous film "the wailing" with big social attention, having 6.8 million audience. I will seek the better way to developthis movie, in terms of artistic dignity and depth as an public-art. With great depth, the realistic application of cultural inheritance, holding mankind common, such as culture, philosophy, religion, history, would be an essential proposition for obtaining cultural emotional empathy from the people in the society. Based on this, the theme and massage from a director, should be expressed in order to be a master piece work beyond time and space in the film history.

Jean Renaudie was an French architect who designed many urban social housing in France, especially in the city of Ivry-sur-Seine, near Paris, with Renee Gailhoustet, co-responsible as the architect of this city, communist city from long time. He was formed as an architect by the influence of Auguste Perret and Marcel Lods, two french architects, great specialist of the structure of concrete. He formed the Atelier Montrouge with Pierre Riboulet, Gerard Thurnauer, Jean-Louis Verret, and proposed many innovative projects, based on geometrically pure forms and masses. After he joined Renee Gailhoustet, the architect of the City of Ivry-sur-Seine, as a co-responsible for the redevelopment of this ideologically communist city. His urban housing concept approached to take the function as a space to welcome the urban life of the resident, not to offer the physical provision of housing repeating the simple housing unity. He accentuated the social role of Housing project not only as the level of a personal home but also as that of an urbanism. He offered divers choice opportunity to the citizen by the urban functional complex through his efforts to make characteristic complex of urban housing, and by the consequence, the innovative result was done which ameliorated the quality of life for resident. This is an exceptional example, not only in France but even in whole over the world. But the maintenance of building against the oldness and the closing shop of inside commercial zone of Jeanne Hachette became a problem, not only that of physical amelioration but also that of spiritual conservation of the works of Jean Renaudie.
