The out-of-plane response of infill walls has recently gained a growing attention and has been recognised fundamental in the damage assessment of reinforced concrete and steel framed buildings subjected to seismic loads. The observation of damage after earthquakes highlighted that out-of-plane collapse of masonry infills may occur even during seismic events of low or moderate intensity, causing both casualty risks and unfavourable situations affecting the overall structural response. Even though studies concerning the out-of-plane behaviour of infills are not as many as those focused on the in-plane response, in the last decades, a substantial number of researches have been carried out on the out-of-plane behaviour of infills. In this study, the out-of-plane response is investigated considering different aspects. First, damages observed after past earthquakes are examined, with the aim of identifying the main parameters involved and the most critical configurations. Secondly, the response recorded in about 150 experimental tests is deeply examined, focusing on the influence of geometrical characteristics, boundary conditions, prior in-plane damage, presence of reinforcing elements and openings. Finally, different theoretical capacity models and code provisions are discussed and compared, giving specific attention to those based on the arching theory. The reliability of some of these models is herein tested with reference to experimental results. The comparison between analytically predicted and experimental values allows to appreciate the extent of approximation of such methods.

The purpose of this study is to investigate the overall recognition on attitudes of well-dying and evaluation the importance of planning factors of well-dying space in college students. This will serve as a basis to accumulate materials on the recognition of well-dying and well-dying spaces of various generations of South Korea. This study conducted a survey from October 4th to 8th, 2016 with 119 college students from U University and K University. As the contents of the survey, were comprised of general socio-demographic elements, subjective recognition and attitudes toward well-dying, and the importance of the planning factors of the physical, emotional, social and spiritual environments of the well-dying space. The main results are as follows. (1) The interest of university students on death education is high, and there was a preference for 'home' where they could be comfortable and be with loved ones as the space for dying. Also, in case of events of bereaving them after death, formal grieving ceremonies were undesired. The funeral was desired to be simple, serene, and not too sad. (2) In evaluation of the importance of physical, emotional, and spiritual environmental planning factors, physical environmental factors were considered to be the most important overall, and the recognition of importance of the planning factors of spiritual environment was low.

The purpose of this study is to look for the basic formative elements of housekeeping space of our cultural life which are worthy to succeed and develop by revaluating in modern view and to reveal what we should maintain form the women's view of the housework in those days. In this study, out look on Chosun Dynasty housekeeping is based on the norm of the women in those days. The research on the housekeeping space for norm of the women in those days. the research on the housekeeping space for Chosun Dynasty upperclass is focused on the house built from early till late Chosun Dynasty, which is now a cultural asset. As a result, norm of Chosun Dynasty have created a social wide atmosphere for women to devote herselves to the housekeeping. Moreover the constructions of Chosun Dynasty's upperclass are affected by Korea's natural environment and socio-cultural environment. Primary factors for natural environment are building materials and the change of seasons. Because of changeable seasons, there were places for storing massive commodities. The other primary factors for socio-cultural environment affecting housekeeping space were social positions, and extended family system, worshipping the ancestors standard of living, the theory of“Poong Soo”(風水, a kind of geomancy) and thought of“Yin and Yang, Five Elements”(陰陽五行) and popular belief of that time. Affected by these two environments, the characteristics of housekeeping space for Chosun Dynasty are ; the main building of the house was used as a diverted area for women to work, and was reconstructed for household affairs. There were inefficient points in the housekeeping space of that time and the space remained stagnant because of the restricted sex and the social position of housekeeping doer. But you could find some points that are efficient and functional to adjust in those living conditions. The storehouse, storage barn, shed and soyjar terrace are the specialized storing place, according to the kinds and characteristics of the commodities. the kitchen, for example, is the combinations of many abilities. It is not only for cooking or heating the room, but also for storing drinking water. The hall which was the storing place, housekeeping place and also the place for family events are used as a diverted place. The linked arrangement of kitchen, store house, boudoir and the other rooms. In addition, we can see that the construction of the kitchen for more than tow people could work in.

The IPCC 5th Assessment Report (Climate Change 2013: The Physical Science Basis) was accepted at the 36th Session of the IPCC on 26 September 2013 in Stockholm, Sweden. It consists of the full scientific and technical assessment undertaken by Working Group I. This comprehensive assessment of the physical aspects of climate change puts a focus on those elements that are relevant to understand past, document current, and project future of climate change. The assessment builds on the IPCC Fourth Assessment Report and the recent Special Report on Managing the Risk of Extreme Events and Disasters to Advance Climate Change Adaptation. The assessment covers the current knowledge of various processes within, and interactions among, climate system components, which determine the sensitivity and response of the system to changes in forcing, and they quantify the link between the changes in atmospheric constituents, and hence radiative forcing, and the consequent detection and attribution of climate change. Projections of changes in all climate system components are based on model simulations forced by a new set of scenarios. The report also provides a comprehensive assessment of past and future sea level change in a dedicated chapter. The primary purpose of this Technical Summary is to provide the link between the complete assessment of the multiple lines of independent evidence presented in the main report and the highly condensed summary prepared as Policy makers Summary. The Technical Summary thus serves as a starting point for those readers who seek the full information on more specific topics covered by this assessment. Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased. Total radiative forcing is positive, and has led to an uptake of energy by the climate system. The largest contribution to total radiative forcing is caused by the increase in the atmospheric concentration of $CO_2$ since 1750. Human influence on the climate system is clear. This is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding of the climate system. Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions. The in-depth review for past, present and future of climate change is carried out on the basis of the IPCC 5th Assessment Report.

The key features of maritime accidents are the change of their attributes by new risks from time to time. To prevent maritime accidents in Korea, the impacts by new risks on domestic safety environments should be identified or predicted. The purpose of this paper is to find the hazard factors by new risks on maritime safety in Korea. The meaning of new risks is the elements of accident hazard which is compiled from new or rare or unprecedented events in the worldwide maritime transportations. The problems of new risks are the lacks of optimum countermeasures to mitigate accident risks. Using the questionnaires with 152 event scenarios classified by 20 accident causes, the hazard identification and risk analysis of new risks was performed based on the Formal Safety Assessment (FSA) by IMO. A total of 22 Influence Diagrams, which is to depict the transit flows between accident causes to consequences, is used in the construction of 152 event scenarios. A total of 20 accidents causes is the same contents as the causation factors represented in Statistical Year Book for Maritime Accidents of Korean Maritime Safety Tribunals. After defining the evaluation equations to the response results of questionnaires by 46 experts, the work for risk analysis is carried out. As results from the analysis of 152 scenarios, it is known that the root cause to affect on maritime safety in Korea is the pressure of business competition and it led to the lacks of well experienced crews, the overload of vessel operations and crew's fatigue. In addition, as results from the analysis of 20 accident causes, the three accident causes are to be candidate as main issues in Korea such as the inadequate preparedness of departure, the neglecting of watch keeping in bridge and the inadequate management of ship operations. All of the results are thought to be as basic hazard factors to safety impediments. It is thus found that the optimum Risk Control Options to remove the hazard factors and to mitigate consequences required are the following two factors: business competition and crewing problems.

Most local governments make an attempt to attract tourists through the large-scale development projects or regional festival events. But, its possibility of success is actually low, so they must take care of ecotourism industry which has higher efficiency in comparison with investing expense. Seocheon area couldn't be focused greatly in spite of the excellent ecological and cultural resources. However, there are lots of possibilities to be a new center of ecotourism because of newly opened National Institute of Ecology and National Marine Biology Resource Institute. Therefore, the purposes of this thesis are to analyze several eco-cultural property all over Seocheon, introduce ecotourism, a main function of ecosystem services, and develop the program satisfying 3 elements of ecotourism; natural environment, visitors and residents. In Seocheon located in where the sea meets the river, ecological property could be reorganized into 4 areas in relation to existing famous tourist attractions. As a measure to let visitors stay, we induced them to lodge in the region through the field work. To realize slow life, we designed it so that they can enjoy each landscape slowly. we also suggested the program which can guide visitors onto the vicinity of habitat for migratory birds at the mouth of Geumgang River and Seocheon foreshore nominated as Ramsar wetlands by focusing on National Institute of Ecology and National Marine Biology Resource Institute which will be the Mecca of ecology research. Through this research, there will be an opportunity to satisfy visitors of Seocheon and enrich local residents' lives.

Evacuation process has been considered as one of the most important elements to be managed in public facilities. Although the importance is highlighted through numerous literatures, disaster evacuation planning, particularly fire accidents, faces a number of human behavior related limitations for a similar application to different types of facilities/occupants. To overcome the obstacles including complexity in human behaviors, a number of simulation techniques with limited consideration on human behaviors are utilized to predict foreseeable problems in evacuation process. Therefore, this research aims to propose system dynamics models incorporating human behaviors considering different types of occupants under disaster evacuation events. Analysis on emergent human behaviors such as group forming and interactions under urgent situation are conducted based on the main stream theories in social science field. The results suggest the influences of human behavior factors including cooperative intention, information sharing, and mobility change to evacuation behavior. The implications are expected to provide safety consideration at planning/designing phase of buildings and help facility safety managers for evacuation planning with more realistic management approaches.

The main research is on how to find source stories and develop and utilize content that will properly show the value of Panmunjom and the surrounding DMZ on the Korean Peninsula, which are receiving worldwide attention. Three methods were used as research for the high-end branding of Panmunjom and the surrounding DMZ. The first is the interest of prospective visitors through the travel cycle, using Joseph Campbell's "The Hero's Journey." The second was to incorporate Roland Bart's "third meaning" into the subjective travel and emotional stimulation, which is the trend of modern travel. The third introduced Kevin Lynch's theory and tried to place five elements of the path, edge, district, node and landmark in the core location of Panmunjom. Through the study, the excavation of contents in Panmunjom and the surrounding DMZ needs to be collected to a third meaning using a direct interview method that listens to the stories of related figures as well as organizing historical events. The priority should be given to those over the age of 80 and interviews should be conducted at least three times and over three generations. The process of building it into an archive, selecting a story, and then going through a culture collage and networking and branding takes place in five stages. This can create a virtuous circle of content processing, content utilization, job creation in the region and revitalizing the local economy through discovery of source stories and storytelling. Content development should be able to touch sensibility while saving time, history, place, originality and sincerity. Taking the center between tourism and travel, development and damage concerns, a careful but long-term plan and large-scale discovery of source stories should be made, and a consensus should be formed on the need for proper storytelling.

Collaboration between teacher librarians and parents is one of the very important elements for school library management in characteristics of learning communities and expanding its' administration. These partnerships are necessary to relieve stress and risk conditions and improve ego-resilience of students. This study analyzed cases of student guidance within the partnerships between teacher librarians and parents and then inquired into formal or informal communication channels for their partnerships through written interview with 10 teacher librarians. The results of analyses teacher librarians have appreciated the necessity of collaboration with parents, and they have experienced student guidance, career guidance, reader's advisory and balancing acts between classroom teachers and parents. It turns out that reading programs with parents are formal communication channel rather than institutional committee such as School Library Council and Parents' Library-Assisting Volunteers and Parent Association and Training in the school library are informal communication channels. The teacher librarians also provide periodic reading events and training for parents and they utilize the School Homepage and Educational Newsletters as the main ways of public relation. In order to promote students' ego-resilience through their collaboration, parents should involve in School Library Council as an essential way for formal communication. And parents' role in school library management should be expanded from offering helping hands to activities to read book, library instruction, assisting teacher librarians in the Library-Assisted Instruction and production of teaching mediums.

The development of reliable and objective definitions as well as automated processes for the detection of health care-associated infections (HAIs) is crucial; however, transformation to an automated surveillance system remains a challenge. Early outbreak identification usually requires clinicians who can recognize abnormal events as well as ongoing disease surveillance to determine the baseline rate of cases. The system screens the laboratory information system (LIS) data daily to detect candidates for health care-associated bloodstream infection (HABSI) according to well-defined detection rules. The system detects and reserves professional autonomy by requiring further confirmation. In addition, web-based HABSI surveillance and classification systems use discrete data elements obtained from the LIS, and the LIS-provided data correlates strongly with the conventional infection-control personnel surveillance system. The system was timely, acceptable, useful, and sensitive according to the prevention guidelines. The surveillance system is useful because it can help health care professionals better understand when and where the transmission of a wide range of potential pathogens may be occurring in a hospital. A national plan is needed to strengthen the main structures in HAI prevention, Healthcare Associated Prevention and Control Committee (HAIPCC), sterilization service (SS), microbiology laboratories, and hand hygiene resources, considering their impact on HAI prevention.
