  • Most long-span bridges such as a cable-stayed bridges have a number of long-period modes due to the flexibility, thus the design concept extending the natural period of structures using base isolation system may be difficult to use directly to these structures. But, the effectiveness of LRB for cable-stayed bridges is indicated in several papers. In this study, the guidelines of designing LRB for a seismically excited cable-stayed bridge using benchmark cable-stayed bridge are presented. The design properties of LRB are chosen that the design index(DI) is minimized or little changed for variation of properties. And the seismic performance of designed LRB is also investigated. The consequences show that the perforamnce of designed LRB is better than that of simply designed LRB for several history earthquakes. Moreover, the design properties of LRB are researched to several diffrent dominant frequency of earthquake. The results present that the plastic and elastic stiffness of LRB are affected by the dominant frequency of earthquake.

  • As people have paid much attention to their health along with increased interest in high quality of living, they have managed their health in organized manners. Space is a physical field which directly and indirectly interacts with human life, there is a little research on its therapeutic aspect and it is only negatively applied for development of products and alternative medicine. This study aims to identify research trends and flows targeting previous research on therapeutic approaches in domestic space design and present basic materials on space design approaches in a therapeutic view, which will be helpful in ultimate development of space design in theories and practices. As a result, it was discovered that there were only a few papers which were searched with direct key words on curative environment, which indicates that specific studies as therapeutic approaches are insufficient. When the studies were analysed according to annual publications, research on residential welfare and medical space was active, and research on design methodology, design techniques, and design plans was active, but research on psychology, behaviors, laws and institutions was relatively insufficient, which indicates studies on physical and psychological aspects of space design are necessary. In conclusion, it is suggested that further studies on therapeutic environment for direct and specific persons should be defined and classified although there have been relevant studies in various fields.

  • To find out more efficient ways of implementing health promotion programs and to determine the factors affecting the results of various interventions, we reviewed 73 articles un the effectiveness of health promotion programs. These include the papers on the smoking, alcohol, drug abuse, nutrition(obesity) and stress management etc. Specific interventions evaluated in this review are education based on the lecture or video shows, health-related event activities, modifications of policy or the environment, health risk appraisal etc. By using KIHASA Line of Korea Institute of Health and Social Affairs, National Congress Library Database MEDLINE, we identified 201 articles published from 1980 to Jun. 1979 and finally selected 73 papers which contain the implementation process, and result of each program. The factors used in the analysis of the programs are (1) characteristics of participants (2) interventions evaluated (3) research design (4) length of programs and evacuation point (7) outcome indices (6) effect of program evaluated by each author. The study results did not prove positive effect of education based on lectures or video shows etc. Rather, it was suggested that lecture-based education has negative effect on the result. Event activity such as contest or health festivals has positive effect, and policy change or environmental change is closely related to the event activity. Also, the result shows that the overall effect of programs fur the students is less than that of the programs for the others. The programs conducted over, 1-year are mere likely to have positive outcomes than shorter ones. And, the outcomes of the programs with controlled research design such as experimental or quasi-experimental study tend to be evaluated inferiorly to those with non-experimental design.

  • The use of post-compressed plates (PCP) to strengthen preloaded reinforced concrete (RC) columns is an innovative approach for alleviating the effects of stress-lagging between the original column and the additional steel plates. Experimental and theoretical studies on PCP-strengthened RC columns have been presented in our companion papers. The results have demonstrated the effectiveness of this technique for improving the strength, deformability and ductility of preloaded RC columns when subjected to axial or eccentric compression loading. An original and comprehensive design procedure is presented in this paper to aid engineers in designing this new type of PCP-strengthened RC column and to ensure proper strengthening details for desirable performance. The proposed design procedure consists of five parts: (1) the estimation of the ultimate load capacity of the strengthened column, (2) the design of the initial pre-camber displacement of the steel plate, (3) the design of the vertical spacing of the bolts, (4) the design of the bearing ends of the steel plates, and (5) the calculation of the tightening force of the bolts. A worked example of the design of a PCP-strengthened RC column is shown to demonstrate the application of the proposed design procedure.

  • With industrialization, environmental problems have become severe worldwide as resources are exhausted for mass production purposes and pollutants are produced in excess of nature's capacity to absorb them. Since modernity, urban parks have emerged as an important element for addressing challenges facing urban environments, which include environmental degradation. In 1987, the Brundtland Commission's report presented a sustainable developmental perspective in solving environmental problems and provided ideas for sustainable design and sustainable urban park landscape design. The purpose of this study is to analyze sustainable design applied to Houtan Park in central Shanghai, China from the perspective of social culture preservation, ecological restoration, and economic effect, and to provide the basic data for urban park design in similar areas in the future. This study consists of a literature survey and a field investigation. The field investigation lead to analysis from three perspectives: social culture preservation, ecological restoration, and economic effect. The literature survey examined sustainable urban parks and Houtan Park based on relevant papers, newspaper articles, and reports. Through actual visits (Aug. 28 - Sep. 1, 2018), it also examined the elements of sustainable design that were applied to the architecture. The three sustainable design elements derived from this study, being a sustainable design for the future, will be used as an important basis for developing urban parks for the regeneration of brownfields in many areas in China.

  • The purpose of this study is to derive and type utilization indexes by comparing public design indicators with preceding studies related to closed school facilities, and to derive preliminary classification systems through a correlation review between indicators. Pre-research was conducted in the scope of academic papers, academic journals, research reports, and special act for promoting the utilization of closed school assets. Public design indicators were set in the scope of domestic design guidelines, the Seoul city public design assessment system, the 'Good Building' designation system, and the UK Design Quality Index (DQI). and the design review of the British architects. First of all, the research method looked at laws, procedures and utilization of closed schools, and reviewed the preceding study and domestic and international public design indicators sequentially. Next, the association was reviewed through a comparison between the preceding study and the public design indicators, and a preliminary classification system for the use of closed schools was derived from this.

  • Purpose: This study was to determine the current trend of nursing research as exploring both quantitative and qualitative methodologies, and to provide the explicit direction to improve the quality of published papers. Methods: Total of 366 articles published between 2004 and 2006 was reviewed using the criteria of analysis. Results: There was more number of quantitative studies than qualitative studies. More studies were conducted with subjects who had health problems, and studies that targeted women and elderly population have been significantly increased. In quantitative methodology, utilization of experimental and quasi-experimental designs has been increased, however descriptive study was dominant as yet. In qualitative methodology, studies using grounded theory and phenomenology were frequently published. It was noted that theoretical framework and rational for sample size were rarely presented in quantitative study. Philosophical position and the process of preparation for study, which guided the research, were not clearly described in qualitative study. Conclusion: The findings of this review suggest that published studies have been improved and diversified, however, detailed and clear evaluation tool that assesses study process and method should be developed as a way to further improve the quality of published papers.

  • It has been almost 20 years since Korea has started the research of school facilities, but there has not been any form of organized information or studies done about such a trend of the research. In this respect, this research places its focus on categorizing 44 policy studies initiated and proceeded by different organizations for last twenty years(1983-2004) and 186 volumes of the research about education facility plans and projects released by journal of Architectural Institute of Korea and journal of Korean Institute of Educational Facilities in 17 subjects of this study. It also concentrates on organizing data based on different levels of schools and periods of time as well as understanding the trend. The result of this research is followings. Considering every volume of the paper and the subjects that have previously been treated in those papers, the trend of this study is divided into the first stage of research period(1983-1993), the second stage of research period(1994-2001), and the third stage of research period(2002-present). Of all the papers, there has been the most number of papers objecting elementary schools(110 volumes, 56.1%), and most of them focused on space formation, size, and the present situation of utilization of each classroom in elementary schools. In the meantime, the studies about educational information, application of the media, space formation and size under teachers'consent, two-dimension types, a design of outdoor space(including gardens), the present situation of utilization, remodeling of school facilities, an evaluation of space and recognition-awareness analysis have been mainly done since 1995. Such a result mentioned above provides a sense of understanding about a level of studies about education facilities in our country, and as a basic source for future guidelines of studies and contents, in my personal opinion, it contains a high level of application.
