The purpose of this research is to introduce the simplified equivalent frame model for the equivalent lateral force procedure, the response spectrum procedure and nonlinear procedure according to ASCE7-10 in order to reduce the time of performance and reasonably evaluate the effect of applying the damping system with the various conditions for the analysis and the variable. In this research, the seismic performance assessment and the design of the damping system were conducted through the nonlinear time history analysis based on the performance based seismic design in ASCE7-10 in regard to applying the damping system to apartment buildings which is lately issued. The optimal design based on the 75% of seismic base shear was performed for an apartment building. The seismic performance assessment were conducted to check the safety of the building, and the economic evaluation was performed by comparing the amount of resource for the optimal designed building with the amount of resource for the original building. In addition, hysteresis dampers was applied to the apartment building, and the suggested equivalent frame model was performed using the damping system design in ASCE7-10, then its control effects were proved in the full scale model of the apartment building which was used in this research.

Park Myoung Jin (1903-1957) was a respectable leader who disseminated dental medical education to make our path as the leading dental medical education developing a new global history of dental medicine. Dr. Park was born in Seoul on 3 July 1903. He graduated Kyongseong dental medical school and studied at the pharmacology department achieving his M.D. In 1938, as the president representing the Hanseong dentists association equivalent to the Japanese dentists association, Dr. Park participated in various events. After liberation, Dr. Park tried his best to achieve Korean dental medical education as the pursuit of ideal ego with self-centered ego. He reorganized the Kyongseong dental medical school and incorporated it to the Seoul National University dental college. Even during the Korea war, Dr. Park still sincerely carried out his duties as the director of the Seoul National University dental medical college by recruiting university entrants and turned out graduates. In 1954, Dr. Park as the director of the Seoul National University dental medical college, he frontiered an opportunity to adapt the American dental medicine by sending school staffs to study overseas. On 25 June 1954, Dr. Park received 25 years of meritorius service award presented by Seoul National University Dental Medical College. Further, on 6 Aril 1954, Dr. Park became a member of an academic research committee. In April 1946, Dr. Park was elected as the president of the Chosun Dentists Association(Korean Dental Association). On 19 May 1947, Dr. Park was also appointed as the director of the Korea dental medicine association leading the general meetings and academic conferences from 2nd through the 8th sessions. On 30 November 1954, as the president of the Korea dental medicine association, Dr. Park also published the Korea dental association publications. In 1957, Dr. Park donated the school housing for the principle of the Kyongseong dental medical school establishing the basis for the Korea dentists association center. Dr. Park also participated in establishment of the oral hygiene campaigne, dental administration policy, organization of the specialized subject delegation board members and the dental materials association. On 10 December 1955, we can recognize Dr. Park's respective historical consciousness through his declaration 'history is a true record of historical traces of a national'. Dr. Park was a living witness of the Korean dental industry. Especially, he stated that the origin of the Korean dentists association was in the Hanseong dentists association. Dr. Park overcame the pressure and indignity during the Japanese colonization. The joy of liberation did not last long since he also had to experience the fraticidal tragedy of the Korea war. Dr. Park was a professional dental specialist and a leader researching dental medicine. He was a great leader who understood the dental medicine and dedicated for the dentist association and dental medicine association with compassion for the nation and national as a Korean.

In this study observation records of the National Natural Environment Survey (2008-2012, 2014-2017) and the Korean Natural History Research Information System (KNHRIS) for the common kestrel (2013-2016) were consulted to determine the correlation of the distribution of kestrels in an area and the area's land use type. Distribution characteristics were studied based on data collected over the last 10 years (2008-2017). Findings show that the common kestrel is widely distributed between 4,407 sites registered in KNHRIS in the period of 2008-2012, 3,899 sites in 2014-2017, and 508 sites in 2013-2016. Relationship analysis was conducted for the altitude and urban planning factors of statistics based on a 2017 GIS check to determine the distribution characteristics. The birds' altitude was confirmed to range from 0 to 1,200 metersck but was most commonly observed at less than 100 meters. Above 200 meters, the rate of occurrence decreased rapidly. The rate of occurrence of the common kestrel was highest in Chungcheongnam-do province, followed by Gyeongsangbuk-do, Kyonggi-do, Jeollanam-do and Jeollabuk-do. As urban areas, green areas, commercial areas, and industrial areas the presence of swere positively correlated with the presence of kestrels, the rate of occurrence of the kestrel was higher in those regions. However, there was no significant relationship between the incidence of kestrels and housing construction or residential areas.

This study investigates the characteristics and physical habitat requirements for each Bufo gargarizans life history through a literature survey. After deriving variables for each component of Bufo gargarizans, in order to reduce regional deviations from eight previously studied literature research areas for deriving the criteria for variables, a total of 12 natural habitats of Bufo gargarizanss are selected as spatial ranges by selecting four additional sites such as Umyeonsan Ecological Park in Seoul, Wonheungibangjuk in Cheongju in the central region, Changnyeong Isan Reservoir in the southern region, and Mangwonji in Daegu. This study presents Bufo gargarizans SI, a species endemic to Korea, whose population is rapidly declining due to large-scale housing site development and road development, and develops a Bufo gargarizans HSI model accordingly to improve the function of the damaged Bufo gargarizans habitat and to present an objective basis for site selection of alternative habitat. At the same time, it provides basic data for adaptive management and follow-up monitoring. The three basic habitat requirements of amphibians, the physical habitat requirements of Bufo gargarizans, synthesized with shelter, food, and water, and the characteristics of each life history, are classified into five components by adding space and threats through literature research and expert advice. Variables are proposed by synthesizing and comparing the general characteristics of amphibians, among the previously studied single species of amphibians, the components of HSI of goldfrogs and Bufo gargarizans, and the ecological and physical environmental characteristics of Bufo gargarizans. Afterwards, through consultation with an amphibian expert, a total of 10 variables are finally presented by adjacent forest area(ha), the distance between spawning area and the nearest forest land(m), the soil, the distance from the wetland(m), the forest layered structure, the low grassland space, the permanent wetland area(ha), shoreline slope(%), PH, presence of predators, distance from road(m), presence or absence of obstacles. n order to derive the final criteria for each of the 10 variables, the criteria(alternative) for each variable are presented through geographic information analysis of the site survey area and field surveys of the previously studied literature research area. After a focus group interview(FGI) of 30 people related to the Bufo gargarizans colony in Cheongju, a questionnaire and in-depth interviews with three amphibians experts are conducted to verify and supplement the criteria for each final variable. Based on the finally developed Bufo gargarizans HSI, the Bufo gargarizans habitat model is presented through the SI graph model and the drawing centering on the Bufo gargarizans spawning area

In this study, historical and cultural landscapes were reviewed focusing on Mangjinsan Mountain in Jinju, Gyeongsangnam-do, and the scenic value was examined through this. First, Mangjinsan Mountain was noted in history, as Ansan(案山, a mountain on the opposite side of a housing/grave site) in Jinju, where Bongsu(烽燧, the beacon fire station) is located. Information on Mangjinsan Mountain was gradually doubled due to its status, and the beacon fire station of Mangjinsan Mountain was in charge of defending the Jinju area. Mangjinsan Mountain was described as a symbolic landscape of Jinju. Regarding the etymology of Mangjinsan Mountain, Sung Yeo-Sin(成汝信) analyzed the geography of Jinju and suggested that it was a place name originating from the phoenix. However, looking at various records, it is confirmed that the name of Mangjinsan Mountain is maintained uniformly, but the inscription is not unified. Second, Mangjinsan Mountain became one of the major stage for the Japanese Invasion of Korea in 1592, and in 1597. It is confirmed to be a place which has joys and sorrows, for that it provided an opportunity to win the Siege of Jinju in 1592, but many casualties occurred in 1597. On the other hand, in the area of Mangjinsan Mountain Byeolseo(別墅), temples, and administrative facilities were located to establish cultural history of the time, and in the 19th century, Manggyeongdae Pavilion was built due to the scenic value of viewing Jinju Castle. These are examples of testimony how Mangjinsan Mountain has an important meaning in Jinju's history and culture. Third, in the late Joseon Dynasty, a poem reciting Mangjinsan Mountain appears, which shows that the Mountain has established itself as a scenic site in Jinju. The description of Mangjinsan Mountain is confirmed in the literature that lists the scenic sites of Jinju. On the other hand, writers who lived in Jinju paid attention to the beacon fire station, singing about the peaceful world without war and looking back the history. In the 19th century, Jeonbyeolyeon(a farewell party) was held, which seems to be the result of the beauty of viewing Jinju and overviewing the area. Through the facts, the symbolism and scenic value of Mangjinsan Mountain in Jinju were confirmed.

The history of the APOCP/APJCP goes back to 1999 when a number of interested scientists joined together to form the organization and to launch a new journal to support cancer prevention research in the Asian-Pacific area. Since the initial Founding Conference, some six General Assemblies (GAs) and ten Regional Conferences (RCs) and Special Study Sessions have been organized. Already the decisions have been made for two further GAs and at least three RCs. As of the April issue of 2013, a total of nearly 3,700 papers have already been published in regular issues of the APJCP or special supplements. With support of the Korean National Cancer Center, housing the Chief Editorial Office, the journal is now including approximately 100 papers a month. Although it experienced a set-back by reduction in the Impact Factor (IF) from 1.29 in 2010 to 0.67 in 2011, there are good grounds to expect an improvement in 2012. However, the future of the APOCP/APJCP will continue to depend on its membership, making continuous efforts to attend our conferences and submit good quality manuscripts. It is particularly important to cite papers in the APJCP wherever possible, if the wish is for an IF commensurate with our long term aims. In that sense it is up to all authors, since the journal will continue to have a very positive ploicy towards accepting papers from all countries within the Asian-Pacific, with continue to varied levels of resources. The editorial team looks forward to your considered support. The APOCP also hopes to see you in person at future meeetings, so that you have a more active voice in deciding the best way forward in our cooperative enterprise.

The virtual reality technology is currently used classifying functional types such as the observation operation type, the experimental activity type, the learning information type, the field problem-solving type, and other different types, based on the media's characteristics implementing 3D form of multi-sensory information. Using Virtual Reality, the restoration of the 'Doksu Palace' has been grafted onto J. Keller's ARCS model, suggesting a field restoration concept that reenacts the lives of the people that had been in the field with the cultural heritage and history based on a scenario based scene direction. This paper also summarizes 3 different types of implementation of the field restoration assorting multi-scene direction. Certain limitations exist, due to the fact that a completed prototype hasn't been suggested and that a detailed notion of the housing and 3D audio connection has been omitted.

The National Welfare Pension Act of 1973 and the National Pension Act of 1986 were legislated for an anticipative response to future population ageing. But the enforcement of these acts gained momentum as they became effective tools to realize the present potential demographic bonus. This article investigates the history related to the enactment of these two acts, focusing on these acts' role in raising funds managed by the government (National Investment Fund and National Housing Fund). This article shows the historical origin of full-dress debates on the sustainability of the National Pension Fund.

This research has a significance on providing basic material of landscape ecological planning and open space planning of the future site by selecting Sinseo innovative city area, large residential land development district in rural area, by classifying biotope types and implementing recreational value assessment in the level of area. First of all, as a result of classification of biotope types in research site, total 11 biotope type groups including stream biotope and its subordinate 51 biotope types. Also, as a result of the first value assessment of classified biotopes, there are total 5 types such as vegetation-full natural river, fallow ground in I grade. In addition, it is analyzed that grade II have 18 types, III are 10, IV are 12, the least valuable V are 6. Especially, grassland biotope(GD) was classified into grade II, which is one grade raised, because it is analyzed that it has high value in terms of normal access and availability although it was assessed as grade ill in terms of natural experience quality. Lastly, as a result of the second assessment, special areas for natural experience and recreation(1a, 1b) are 15, areas for natural experience and recreation(2a, 2b, 2c) are 47. Especially, the 52th drawing mark space was grade II in the first assessment but its value grade was upgraded because of its high value in terms of use evidence, size of the area, accessibility with housing area, history and cultural character and so on.

Objectives: Subjective life expectancy (SLE) has been found to show a significant association with mortality. In this study, we aimed to investigate the major factors affecting SLE. We also examined whether any differences existed between SLE and actuarial life expectancy (LE) in Korea. Methods: A cross-sectional survey of 1000 individuals in Korea aged 20-59 was conducted. Participants were asked about SLE via a self-reported questionnaire. LE from the National Health Insurance database in Korea was used to evaluate differences between SLE and actuarial LE. Age-adjusted least-squares means, correlations, and regression analyses were used to test the relationship of SLE with four categories of predictors: demographic factors, socioeconomic factors, health behaviors, and psychosocial factors. Results: Among the 1000 participants, women (mean SLE, 83.43 years; 95% confidence interval, 82.41 to 84.46 years; 48% of the total sample) had an expected LE 1.59 years longer than that of men. The socioeconomic factors of household income and housing arrangements were related to SLE. Among the health behaviors, smoking status, alcohol status, and physical activity were associated with SLE. Among the psychosocial factors, stress, self-rated health, and social connectedness were related to SLE. SLE had a positive correlation with actuarial estimates (r=0.61, p<0.001). Gender, household income, history of smoking, and distress were related to the presence of a gap between SLE and actuarial LE. Conclusions: Demographic factors, socioeconomic factors, health behaviors, and psychosocial factors showed significant associations with SLE, in the expected directions. Further studies are needed to determine the reasons for these results.
