  • This study aims to explore social participation needs among the elderly in Korea from the perspective of the elderly participant's. 40 Q-samples are drawn from the Q-population including attitudes and needs toward social participation in later life based on news articles, essays, research, documentary, and television shows. 35 subjects are analysed by the QUANL program and the types of social participation needs are divided into four patterns which accounted for 60.16% of the total variance. The elderly's portrayal of an ideal social participation is about making independent decisions and being able to actively participate in the activities they chose to do. However, their most undesirable scenario would be being confused and uncertain of what they should do the remainder of their lives. The needs of social participation among the elderly varies on four indicators such as ego, social capital, life satisfaction, life vitality and these four indicators have two sub-categories with a total of 8 types of classification. These 8 types differ by priorities, adaptation to life changes, motivation to social participation, and desired activity. Findings suggest that researchers and policy makers need to consider service user perspective on social participation in later life, not service provider perspective.

  • Indobufen ($Ibustrin^{(R)}$), a reversible inhibitor of platelet aggregation, exists in two enantiomeric forms in 1:1 ratio. Here, we characterized the anti-platelet effect of S- and R-indobufen using response surface modeling using $NONMEM^{(R)}$ and predicted the therapeutic doses exerting the maximal efficacy of each enantioselective S- and R-indobufen formulation. S- and R-indobufen were added individually or together to 24 plasma samples from drug-naïve healthy subjects, generating 892 samples containing randomly selected concentrations of the drugs of 0-128 mg/L. Collagen-induced platelet aggregation in platelet-rich plasma was determined using a Chrono-log Lumi-Aggregometer. Inhibitory sigmoid $I_{max}$ model adequately described the anti-platelet effect. The S-form was more potent, whereas the R-form showed less inter-individual variation. No significant interaction was observed between the two enantiomers. The anti-platelet effect of multiple treatments with 200 mg indobufen twice daily doses was predicted in the simulation study, and the effect of S- or R-indobufen alone at various doses was predicted to define optimal dosing regimen for each enantiomer. Simulation study predicted that 200 mg twice daily administration of S-indobufen alone will produce more treatment effect than S-and R-mixture formulation. S-indobufen produced treatment effect at lower concentration than R-indobufen. However, inter-individual variation of the pharmacodynamic response was smaller in R-indobufen. The present study suggests the optimal doses of R-and S-enantioselective indobufen formulations in terms of treatment efficacy for patients with thromboembolic problems. The proposed methodology in this study can be applied to the develop novel enantio-selective drugs more efficiently.

  • This study developed prediction models of chlorine bulk decay coefficient by each condition of water quality, measuring chlorine bulk decay coefficients of the water and water quality by water purification processes. The second-reaction order of chlorine were selected as the optimal reaction order of research area because the decay of chlorine was best represented. Chlorine bulk decay coefficients of the water in conventional processes, advanced processes before rechlorination was respectively $5.9072(mg/L)^{-1}d^{-1}$ and $3.3974(mg/L)^{-1}d^{-1}$, and $1.2522(mg/L)^{-1}d^{-1}$ and $1.1998(mg/L)^{-1}d^{-1}$ after rechlorination. As a result, the reduction of organic material concentration during the retention time has greatly changed the chlorine bulk decay coefficient. All the coefficients of determination were higher than 0.8 in the developed models of the chlorine bulk decay coefficient, considering the drawn chlorine bulk decay coefficient and several parameters of water quality and statistically significant. Thus, it was judged that models that could express the actual values, properly were developed. In the meantime, the chlorine bulk decay coefficient was in proportion to the initial residual chlorine concentration and the concentration of rechlorination; however, it may greatly vary depending on rechlorination. Thus, it is judged that it is necessary to set a plan for the management of residual chlorine concentration after experimentally assessing this change, utilizing the methodology proposed in this study in the actual fields. The prediction models in this study would simulate the reduction of residual chlorine concentration according to the conditions of the operation of water purification plants and the introduction of rechlorination facilities, more reasonably considering water purification process and the time of chlorination. In addition, utilizing the prediction models, the reduction of residual chlorine concentration in the supply areas can be predicted, and it is judged that this can be utilized in setting plans for the management of residual chlorine concentration.

  • Images captured by drone have the advantage of quickly constructing spatial information in small areas and are applied to fields that require quick decision making. If an image registration technique that can automatically register the drone image on the ortho-image with the ground coordinate system is applied, it can be used for various analyses. In this study, a methodology for geo-referencing of a single image and sequential images using drones was proposed even if they differ in spatio-temporal resolution using linear features and distinct points. Through the method using linear features, projective transformation parameters for the initial geo-referencing between images were determined, and then finally the geo-referencing of the image was performed through the template matching for distinct points that can be extracted from the images. Experimental results showed that the accuracy of the geo-referencing was high in an area where relief displacement of the terrain was not large. On the other hand, there were some errors in the quantitative aspect of the area where the change of the terrain was large. However, it was considered that the results of geo-referencing of the sequential images could be fully utilized for the qualitative analysis.

  • Korean government has taken positive policies, including making "An Basic Plan on the Conservation and Activation of the Royal Tombs of the Joseon Dynasty, UNESCO World Heritage", since 40 royal tombs of the Joseon Dynasty were inscribed as UNESCO World Heritage in 2009. However, projects utilizing the royal tombs of the Joseon Dynasty are in the beginning step and very few has been researched on those projects academically. This study analyzed total 311 projects utilizing the royal tombs of the Joseon Dynasty, which have been made by the Cultural Heritage Administration of Korea from 2009 to 2014, through the literature review and content analysis methodology. An analysis frame consists of educational, touristic, compound and industrial activation on the basis of the utilization types made by the Cultural Heritage Administration of Korea. Most projects utilizing the royal tombs of the Joseon Dynasty are in the very beginning step in terms of educational and touristic utilization. No project utilizing the royal tombs of the Joseon Dynasty in terms of industrial utilization is found. Those projects are almost similar without distinctive characteristics peculiar to each royal tombs. Most projects have been taken on the short term level and the budget size for those is not enough. Projects are mostly focused on the on-site of royal tombs with little paying attention to converging projects utilizing digital and on line techniques. Some suggestions are the followings: increase of the budget on projects utilizing the royal tombs of the Joseon Dynasty, development of content peculiar to each tomb, development of industrial projects, development of converging projects utilizing digital and on line techniques, establishment of new medium and long term plans for utilization of the royal tombs of the Joseon Dynasty and so on.

  • The more income and free time people have, the more interest in cultural heritage they get to improve the quality of life. In light of this, Local governments put more effort to create colorful events using their cultural heritage resources, and the central government also starts to implement policies to enhance the value of cultural heritage. To keep those efforts on utilizing cultural heritage, however, several issues seem to be addressed in advance. Firstly, it needs to define the concept of cultural heritage utilization that could cover its current policy trend. Secondly, the utilization methodology should be categorized and classified. Therefore, the study for those issues should be carried out to utilize the cultural heritage efficiently and systematically. This study contains the current status of the relevant policies and projects; the trend and meaning of the utilization. And, in this study, the cultural heritage utilization was defined as all activities producing positive effects or influences by cultural heritage such as enjoying cultural heritage values and creating additional profits. Furthermore, the cultural heritage utilization was categorized according to several criteria; the value, the objective, and the type of cultural heritage utilization. Finally, the final part of the study includes proposals on the future policy direction of cultural heritage utilization.

  • A short-turn bus is a bus that is operated within a subsection of an existing bus line. Previous studies regarding short-turn buses decided optimal turn-back points for a single bus line rather than a bus network. Also, in-vehicle crowding which has a significant impact on transit convenience was rarely considered. Therefore, this study aimed to develop a methodology to set priorities for the introduction of short-turn buses of bus lines and sections, considering crowding. To achieve this objective, we calculated occupancies and crowding alleviation benefits of existing bus lines overlapping a new short-turn route based on transit card data, before and after the introduction of short-turn strategy. Also, operator and social costs caused by the introduction of short-turn buses were calculated. Those procedures were iterated over bus lines and sections to operate a short-turn service, and a section whose benefit-to-cost ratio (B/C) is the largest in a line was selected to operate a short-turn service in the line. After, priorities of bus lines to introduce short-turn services could be determined based on B/C values, and the optimum total fleet size could be determined when a short-turn strategy is applied in multiple lines.

  • This study explored to analyze the winning determinants of the lawsuit cases on the urban and housing redevelopment project based on jurimetric methods. Based on affirm-rate and staircase matrix tables, 441 lawsuit judgments are analyzed. Research findings in affirm-rate analysis indicate that past legal relation, no own defect of accreditation, no ownership or association member status, lapse of period of litigation, and no legal interest are identified as higher rate in order for the reason for plea on the merit. And so are defect on calculation of consent rate, defect in relation with written consent, approval before zoning designation, defect in relation with general meeting, and defect on zoning designation for the issue on the merit. It is noteworthy from the staircase matrix table analysis that the criteria for affecting the lawsuit outcome is determined based on key forecasting variables such as past legal relation and no ownership or association member status. This study intends to provide the implication that the unnecessary disputes can be reduced in the urban and housing redevelopment project by the implementation of jurimetric quantitative analysis methodology from the perspective of empirical law.

  • Standards-curriculum based archival contents for education is the best effective teaching and learning units for historical thinking abilities. This paper purposes a developing procedures of an archival contents for education that is theoretical instructions of developing an archival contents for education by the National Archives of Korea. This paper can be used of the theoretical bases for the National Archives of Korea by proposing the methodology of development of an archival contents for education. The developing procedures of an archival contents for education is the same with the procedures of developing an e-learning contents that has planning, analyzing, designing, developing and assessing steps but it is characterized by an archival contents for education that is curriculum standards analysis, collection analysis, and detailed design for structured formats in effective-accomplishments for teaching-learning objectives. I propose the procedures for determining teaching-learning subjects that enable the development of an archival contents for education by curriculum standards analysis. I also propose the procedures for deriving the key words from the teaching-learning subjects. Collection analysis methods analyze key records that correspond to the learning subjects according to the selection criteria of primary sources. In the steps of designing, titles of contents and contents structures have to be determined and storyboards based on flowchart of learning have to be made of according to the results of analyses. In the steps of developing contents, making a copy of primary sources like a original is the key points. And also in the steps of assessment, products of teaching-learning contents to effectively achieve the teaching-learning objectives have to be estimated by the appraisal board. Finally I propose that user's survey research after the services have to be reflected on contents updates and new developments of contents.
