PURPOSE: Focusing on the factors that influence the infectious disease emergency response policy (approached by dividing the factors into health policy management and economic policies), both SARS and MERS cases were based on the legal system, manpower, and budget, but there has not been enough learning from the epidemic. This study focused on infectious disease emergency governance, which various studies have neglected despite its social and academic importance. METHODS: The research is based on an analysis of SARS, MERS, and COVID-19 and compares global policies. In this study, infectious disease emergency governance was divided into health policy management and economic factors. This study focused on planning and leadership before and after the outbreak of infectious diseases and how cooperation was achieved to monitor and respond to infectious diseases successfully. RESULTS and CONCLUSION: The limit of this study was that COVID-19 is a currently ongoing infectious disease with high uncertainty. Because it is an ongoing problem, only some data and statistics are reflected, and many limitations prevent a proper comparison under the same criteria as other infectious diseases. In addition, because continuous changes are expected, there is also room for infectious diseases to develop in a completely different pattern from the current situation, and continuous research must be accompanied in the future.

Hospice is the wholistic caring service for terminally ill patient and his family so that he can live in dignity and maintain the quality of life until he passes away peacefully. The purpose of this study is to compare the development of hospice movement in UK, USA, Japan and Korea, to analyze space configuration characteristics of facilities built between 1980-2009 through case study. The result is as follows. First, The modern hospice started in England and it has spread around the world rapidly. In Korea, hospice service was introduced even prior to US and Japan and developed in spite of poor medical environment. The application of health insurance subsidies were late compared to other countries, but the hospice and palliative care system was quickly set on the basis of precedent cases. Second, the number of hospital beds per facility is decreasing, and it has been divided into smaller clusters for the residential atmosphere. The controversy between private rooms and multi-patient room is still ongoing, and increasing facilities without in-patient service. Rather than establishing uniform and absolute regulations, it is necessary to design a flexible space which can cope with various situations such as patients' needs, service changes, and manpower status. Third, the spaces for family members and friends to stay in both private rooms and communal spaces are increasing. Forth, Facilities for patients with different needs, such as children and adolescents and AIDS patients, have been developed in UK and USA. Further research on of patients' diverse needs and customized environmental support is necessary.

The purpose of this study is to suggest a supervisory way to improve the efficiency of Building Supervision using Deep Learning, especially object detecting technology. Since the establishment of the Building Supervision system in Korea, it has been changed and improved many times systematically, but it is hard to find any improvement in terms of implementing methods. Therefore, the Supervision is until now the area where a lot of money, time and manpower are needed. This might give a room for superficial, formal and documentary supervision that could lead to faulty construction. This study suggests a way of Building Supervision which is more automatic and effective so that it can lead to save the time, effort and money. And the way is to detect the hoop-bars of a column and count the number of it automatically. For this study, we made a hoop-bar detecting network by transfor learnning of YOLOv2 network through MATLAB. Among many training experiments, relatively most accurate network was selected, and this network was able to detect rebar placement in building site pictures with the accuracy of 92.85% for similar images to those used in trainings, and 90% or more for new images at specific distance. It was also able to count the number of hoop-bars. The result showed the possibility of automatic Building Supervision and its efficiency improvement.

건설 프로젝트에서 공정계획은 사업 성패의 중요한 요인으로 작용한다. 그 중 공동주택 마감공사는 기초공사나 골조공사에 비해 작업 간의 간섭이 많다. 이로 인해 마감공사 시 공정관리 효율성 증대를 위한 Tact 공정관리기법이 적용되고 있다. Tact 공정관리는 작업 흐름이 일정하게 발생할 수 있도록 관리하며 마감 단위층을 통일시켜 작업속도를 균등화시킨다. 그러나 세부공종을 고려하지 않고 모든 작업이 균일하게 동기화되어 공사비가 증가하고 비효율적인 공정관리가 나타난다. 본 연구는 세부공종의 특성을 고려할 필요가 있다고 판단되어 기존 Tact 공정관리방식의 한계점을 파악하고 개선하고자 세부공종을 고려한 복합병행 Tact기법을 제안한다. 또한 기존 Tact기법과 복합병행 Tact기법을 비교분석하여 도출한 결과를 기반으로 복합병행 Tact기법의 타당성 및 실효성을 검증했다.

The Korean government has invested a tremendous amount of money in the last 10 years to build large public research infrastructures (LPRI). For efficient operation and maintenance of LPRI built with expensive equipment and professional engineers, reasonable budget needs to be allocated. However, it is difficult to fulfill sustainable operation and maintenance (O&M) because there is no standard on budgeting for efficient LPRI operation, including expensive equipment and manpower allocation. There have been a lot of cost assessment studies regarding O&M of high-demand facilities such as hospitals, hotels and residential buildings, but a very few on sustainable O&M of LPRI. Therefore, mid/long-term budget establishment plans for efficient LPRI O&M are required from the initial planning stage and a cost assessment model to support the plans should be developed. The objective of this paper is to propose a cost assessment model for sustainable operation and maintenance of large public research infrastructures. To do so, actual O&M data of 6 LPRI types in operation are collected, and regression analysis model (RAM) is used for development and evaluation a cost assessment model. The study result will support sustainable operation of LPRI from a business perspective and be used as basic data for continuous development of cost assessment models to establish budgets for LPRI operation from an academic perspective.

Due to rapid decrease in population of farming and fishing villages and drain of young rural manpower to the cities, aging is being intensified, and the conditions of housing and welfare of elderly households are inadequate. Currently, group home is being discussed as part of specialized housing and welfare support policy for the people in the vulnerable class with poor self-supporting abilities such as the aged living alone in farming and fishing villages, and aged farming and fishing households. So the purpose of this research is to present the basic data for proposing the policy of supplying group home through examining the realities of housing and welfare of the people in the vulnerable class in farming and fishing villages. Survey was conducted on the 4 regions -Cheonan-si, Gongju-si, Yesan-gun, and Seosan-si - whose apartments were all occupied by the residents among the group homes for the elderly living alone in Chungcheongnam-do and the following results were derived from the analysis on the data collected from the survey. First, great effects can be attained at small costs by reorganizing and utilizing the public facilities that are unused or little used and the existing houses that are exposed to risks due to improper maintenance. Second, it can be pointed out that the residential environment of the vulnerable members of society was improved without impairing the existing village landscape. Third, housing welfare was enhanced without investing a large sum of money and the system to promptly cope with negligent accidents and emergency can be built and operated. Fourth, the cases promoted to solve the problems of the poor, unhygienic, and unsafe housing of the elderly and the vulnerable members of society were very positive and well worthy of being presented as planning direction of future group homes in farming and fishing villages. Finally, if they are operated entirely for free, it will cause the lack of the sense of ownership and the problems in securing the budget, so the ways of paying minimum individual housing expenses should be examined. The alternatives of housing welfare for the vulnerable members of farming and fishing villages are needed and the ways of constructive planning and researches should be continuously made. Also, the government's support policy should be actively promoted.

In order to see the development of Nursing related research activities in Korea over the last three decades, abstracts of almost all of the Master and Ph.D theses that appeared from 1961 up to August 1991 were collected. The number of theses was 2354, from which an index of key words has been constructed. Key words were defined as those terms in each thesis title that convey major objectives of the given thesis study and the important nursing concepts dealt with in the thesis. Although all the key words were picked from the thesis title only, full use was made of the abstracts in deciding the principal objectives and essential contents of the thesis studies and their important concepts as well. In total, 539 kinds of key words were identified from the 2354 titles, and the identified words were all found to be in the International Nursing Index. On an average each title has two key words. Which key words were most frequently used, how they have changed with time, what kind of concept is preferably dealt with by each graduate school, and the concepts to which a given key word is likely to be connected were examined. The results are summerized below : 1) For each decade the theses numbers were as follows : 54(2.3%) from the 60’s, 413(17.5%) from the 70’s, 1523(64.7%) from the 80’s, and 364(15.5%) from the 90’s. Master’s thesis contributed 96% (2252) of the papers and Ph. D’s theses filled the remaining 4%(102). 2) A total of 539 key words were used, averaging about 2 for each thesis. The most frequently used key words were ‘Nurse’, ‘Anxiety’, ‘Knowledge / Attitude /Practice’, ‘Stress /Stressor’, ‘Attitude’, ‘Job-Satisfaction’, ‘Mental Disorder’, ‘Operation’, ‘Elderly’, ‘Nursing Role’. 3) Each decades key words can be classified as : the 60’s : ‘Nursing Education’, ‘Pulmonary Tuberculosis’, ‘Mother-Child Health’, ‘Growth & Development’, ‘Public Facilities’, ‘Mental Disorder’ : the 70’s : ‘Nurse’, ‘Family Planning’, ‘Attitude’ / ‘Knowledge, Attitude / Practice’, ‘Curriculum in Nursing Education’, ‘Clinical Practice in Nursing’, ‘Analysis of the Work of the Nurse’, ‘Health Education of School’, : the 80’s : ‘Nurse’, ‘Anxiety’, ‘Stress /Stressor’, ‘Operation’, ‘Nursing Role’, ‘Job Satisfaction’ : the 90’s : ‘Nurse’, ‘Elderly’, ‘Family-Support’, ‘Stress /Stressor’, ‘Home Care’. Key word ‘Nurse’ appears continuously and most frequently through the years, which indicates that there has been active study of the characteristics of nurses and related fields. The concept ‘Anxiety’ has been studied steadly from the 80’s and it shows that interest in health and disease are increasing Which comes as a result of society changing to an industrial and informational community. 4) Looking into each graduate school’s study area key words ‘Anxiety’, ‘Nurse’, ‘Mental Disorder’, ‘Stress /Stressor’, ‘Operation’, ‘Attitude’, ‘Hemo-dialysis’, were studied in the regular graduate school : ‘Family Planning /Contraception’, ‘Knowledge / Attitude /Practice’, ‘Physical Health-State /Physical Health Examination’, ‘Nurse’, ‘Using Clinical Facilities’, ‘Health Education of School’, were studied in the Graduate School of Public Health’ ; ‘Nurse’, ‘Anxiety’, ‘Stress / Stressor’, ‘Job-Satisfaction’, ‘Clinical Practice Education’, ‘Nursing Education’, were studied in the Graduate School of Education : ‘Nurse’, ‘Job Satisfaction’, ‘Nursing Role’, ‘Administration - Employment /Employment Management’, ‘Leadership’, ‘Personnel Profile’, ‘Nursing Manpower / Changing Working Place’, were studied in the Graduate School of Public Administration. 5) The Connection between key words were : ‘Nurse Job Satisfaction’, ‘Stress / Stressor ⇔ Coping / Ajustment’, ‘Nurse ⇔ Nursing Role’, ‘Anxiety ⇔ Giving Information’, ‘Nurse ⇔ Stress / Stressor’, ‘Anxiety ⇔ Operation’, ‘Nurse ⇔ Burnout’, ‘Knowledge, Attitude, Practice ⇔ Family Planning’, ‘Nurse Administration ⇔ Employment’, ‘Anxiety Muscle ⇔ Relaxation Technic’, ‘Anxiety ⇔ Mental Disorder’. From the above it can be noted that many nursing concepts were handled in the thesis titles. But there were more than enough papers on the characteristics of the nurse. It is suggested that in depth research be made on ‘Nursing Accidents’, t-‘Ethics’, ‘Nurse - Patient Interactions’, ‘Spritual Care’, ‘Dying’, ‘Hospice’, ‘Resident Helper’ and that there should be in depth research relating to the physical and mental development of youth and in particular physical concepts like ‘Drug - Abuse’, ‘Child -Abuse and Teaching’.
