  • 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.

  • 비교적 짧은 역사를 지니고 있는 미국과 호주에서도 조차 역사유산, 문화유산에 대한 보존 및 재사용에 대한 중요성을 크게 인식하고 이를 보존, 활용하는 데에 매우 체계적이고 현실적인 방안을 모색하여 이를 실천하고 있다. 반면, 반만년이란 오랜 역사를 지니고 있는 우리나라의 경우, 소중한 건축유산을 어떻게 보존하고 다시 사용해야 하는지에 대한 복원 시스템 및 활용방안에 대해 명확한 기준들이 매우 부족한 것이 현실이다. 본 논문은 이렇게 역사가 짧고 따라서 역사, 문화유산이 그리 많지 않을 것 같은 호주, 미국을 대상으로 이 나라에서의 이들 유산에 대한 보존 및 활용방안이 어떻게 이루어지고 있는 지를 사례를 통하여 그의 제도와 시스템을 면밀히 조사, 분석하고자 하였다. 이를 통하여 지금까지 재개발에 의해 한순간에 사라져 갔던 우리들의 옛 건축, 구도심 환경, 특히 현재의 건축물들에 대한 인식 제고와 일괄적인 재건축에서 벗어나 역사와 함께 건축적 환경이 지속될 수 있는 건축물 및 도시환경의 가이드라인을 제시하고자 하였다.

  • 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.

  • 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.
