Construction program management requires more systematic management than traditional management methods due to the complexity of the project and various stakeholders. In particular, the systematization of closure phase of the process is in urgent need as there is a difference between the owner's expectations and the contractor's deliverables, resulting in delayed handovers, conflicts, frictions, and increased legal disputes. This study identified the process and activities of closure phase through domestic and international literature and case studies for the successful closure of the construction program. Further, the proposed processes and activities were verified through expert verification for appropriateness and the possibility of application to the site. By utilizing the processes and activities proposed in this study, the project aims to overcome the limits of closure phase and improve the satisfaction of the owner, as well as to enhance the global competitiveness of domestic construction companies.

Purpose: The purpose of this study was to analyze the impact of healthcare accreditation and to provide empirical evidence to validate positive effectiveness. Methods:Six electronic databases (KERIS, KoreaMed, NDSL, Ovid-medline, Embase, Cochrane library) were accessed in May 2016. Keywords used were 'accreditation' and 'Joint Commission on Accreditation of Healthcare Organization (JCAHO)'. Of the initially identified 3,008 articles, 60 studies on healthcare accreditation were selected based on inclusion criteria that are hospital accreditation, accreditation by disease and clinical center accreditation. These were retrieved and analyzed. Result: The 60 study results were on the impact of healthcare accreditation. Results were classified into four perspectives of Balanced Score Card (Financial, Customer, Internal Process, Learning & Growth). In internal process perspective, results revealed that healthcare accreditation has made a positive impact on "care process and procedure". In learning & growth perspective, healthcare accreditation has made a positive influence on "leadership", "organizational cultures" and "change mechanisms". However, it revealed that healthcare accreditation does not directly affect financial performance. It is also difficult to reach a definitive conclusion that healthcare accreditation programs affect patient satisfaction of customer and clinical outcome of the internal process. Conclusion: Healthcare accreditation programs provide positive impact on change of care process and building communication-oriented hospital culture. However, more rigorous and diverse research is needed on financial effects and clinical outcomes of healthcare accreditation.

This study has developed a design indicator required to promote green remodeling in school facilities. And, implemented the green remodeling pilot test on the school facilities that are planning actual remodeling. This pilot test suggested user participation design methodology such as verification of the developed design indicator, design goal setting, evaluation and adjustment of design proposal. The Green Remodeling Design Indicators were classified into 3 large categories of architectural performance, usability, and design through analysis of cases related to 'green buildings' and 'remodeling'. We have developed nine middle categories such as architectural and structural performance, facility performance, environmentally-friendly, circulation, space, amenity, harmony with surroundings, form and symbolization. In addition, 42 detailed indicators were developed for each category, including general, functional, and special indicators. For the verification of this study, two green remodeling design workshops were conducted for Gwangju J elementary school. The first design workshop presented the importance of the design indicator and set the goal of the design plan of green remodeling for project. And, the second Workshop presented the evaluation of the satisfaction with the design and the direction of future adjustment for project. The design indicator developed in this study can be utilized as a design indicator of design quality management and decision system for the school green remodeling in the future.

Purpose: Healthcare is on the whole a personal and critical service that consumer's use, whereas hospitalization is as a rule painful, because nature nurtures and Sun Light Luminosity for healthcare settings is considered healing. The performance and design of climate responsive buildings such as AKU requires a detailed study of attributes of climate both at micro as well as macro level. The therapeutic value of contact with nature through window view, greenery and landscape is calculated there. Method: A two prong strategy is been devised for this article, at micro level three typical morphologies are analysed by creating same environment of neighboring building on sun shading chart, radiation and temperature range. Since the analysis of local climate helps to determine the design strategies for hospital Healing Environment which is suitable for Karachi climate; in order to track the macro climatic behaviour, a considerable analysis of psychometrics chart for AKU Karachi are designed on Climate Consultant (CC) and analysed by Machine Learning. Climate Consultant proposes different design strategies suitable for Karachi. And on the other hand time wise illumination sources for clinical area which are then measured on psychrometric chart- according to singular space: multi patient admission, secondly: acute ambulatory ward, and tertiary: multi windowed space according to the mushrabiyah and sky light pattern. Result: Our findings support the hypothesis that windowed wall is 75-80% more healing wall; an accelerated evidence was found for healing at macro level if the form of the hospital is designed according to the climatologically preferences, whereas at micro level: the light resource becomes the staff attentiveness determinant. In Conclusion evidence was provided that the actual form of luminosity results consequently in satisfaction while light entering from several set of windows and other sources might be valued if design according to the healing environment. The data added on the sun shading chart to calculate rays entraining into space in patient room equal to 124416.21 Watts/ meter $m^2$ is calculated as precise healing rate-and is confirmed by questionnaire from patients belonging from each clinical stage having different illnesses.

In contemporary Korean society, urban community environment is often associated with high-density and high-rise residences that make people's relationships superficial, instrumental and impersonal. Furthermore, urban community consistently interplays with neighboring residents and childhood emotional experience are influential on their unconscious images and attitude about their current neighborhood environment, while affecting the environmental attitude and the formation of community sense. Previous research found evidences that increased level of community sense is fostering more feeling of living in so-called "real neighborhood environment." This study aimed to cross-culturally examine what the respondents' emotional perception and their attitude were about the community environment in their childhood through environmental autobiography method and to examine the effects of the results on adults' formation of sense of community for their current community environment. Extensive literature review explored a few important theoretical framework which are closely related to sense of community (SOC) as a result of emotional experience: membership, influence, integration and fulfillment of needs, shared emotional connection and community satisfaction. Chi-square and GLM analysis revealed that there were no demographic, and socio-economic differences between two groups of Korean and US residents. Correlation analysis indicated that childhood emotional experience of Koreans and US citizens was statistically significant on sense of community for their current living community. Multi-regression analysis also found that the degree of influence were the main predictors for building strong sense of current community throughout a cross-cultural group. Furthermore, the relationship between various emotional experience of each factor in previous and current community environment were statistically significantly related. It is concluded that as the positive childhood experience of influence in their past community was going up, the level of sense of community for their current community was strengthened across their cross-cultural background.

In this study, we analyzed the current status and limitations of software education in A education universities. In order to solve these problems, technical support assistant teachers were employed and operated. During the course of the course, we conducted interviews with the instructor and the technical support teacher. The satisfaction of the teacher in the training school was high and I wanted to be supported continuously. It also called for the capacity building of assistant teachers and the establishment of a pool of staff. On the other hand, the assistant teachers suggested that the role assignment of team teaching should be clarified and a guide of activities should be presented. The technical assistance assistant teacher input system discussed in this study may be different from the practice system of each university, and generalization may be limited. Therefore, it is expected that the effective implementation method will be shared and the software education will be activated.

The purpose of this study was to establish a model for constructing longitudinal data for medical school, and to structure cohort and longitudinal data using data from Yonsei University College of Medicine (YUCM) according to the established input-environment-output (I-E-O) model. The study was conducted according to the following procedure. First, the data that YUCM has collected was reviewed through data analysis and interviews with the person in charge of each questionnaire. Second, the opinions of experts on the validity of the I-E-O model were collected through the first expert consultation, and as a result, a model was established for each stage of medical education based on the I-E-O model. Finally, in order to further materialize and refine the previously established model for each stage of medical education, secondary expert consultation was conducted. As a result, the survey areas and time period for collecting longitudinal data were organized according to the model for each stage of medical education, and an example of the YUCM cohort constructed according to the established model for each stage of medical education was presented. The results derived from this study constitute a basic step toward building data from universities in longitudinal form, and if longitudinal data are actually constructed through this method, they could be used as an important basis for determining major policies or reorganizing the curricula of universities. These research results have implications in terms of the management and utilization of existing survey data, the composition of cohorts, and longitudinal studies for many medical schools that are conducting surveys in various areas targeting students, such as lecture evaluation and satisfaction surveys.
