Recently, deep learning-based image recognition systems have been adopted to various surveillance environments, but most of them are still picture-type object recognition methods, which are insufficient for the long term temporal analysis and high-dimensional situation management. Therefore, we propose a method recognizing the specific dangerous situation generated by human in real-time, and utilizing deep learning-based object analysis techniques. The proposed method uses deep learning-based object detection and tracking algorithms in order to recognize the situations such as 'trespassing', 'loitering', and so on. In addition, human's joint pose data are extracted and analyzed for the emergent awareness function such as 'falling down' to notify not only in the security but also in the emergency environmental utilizations.

To accept the doctor's professional negligence in the medical malpractice, the mistakes, by which the doctor did not foresee the production of the results in spite of the possibility of foresight and did not avoid the production of the results in spite of the possibility of avoidance, must be considered, and to decide the presence of the doctor's professional negligence, the standard must be the attention standard of general-common doctor engaged in the same business and the same function, and the medical enviornments, the conditions, the extraordinary nature of medical behavior, and etc should be considered by the general level of medical science at the time of accident. This principlel must be applied to the medical malpractice case occurred being on duty without exception. But, because of the extraordinary nature of duty work, it is difficult for any doctor to do one's best technical practice by making all diagnosis, medical treatment with all the equipment on the same plane as the ordinary times. That cannot be also expected for any doctor to do one's best technical practice in the terms of a social idea. From this point of view looking into The Precedent case related to Medical-service person being on duty sentenced by The Supreme Court, unlike the general medical malpractice case, the presence of the professional negligence in the medical malpractice occurred being on duty seems to be decided with more consideration on the general level of medical science, the medical enviornments and the conditions, particularities of medical practice at the time of accident. Especially, the extraordinary nature of medical behavior of the medical service person being on duty in the emergency room seems to be admitted compared to that of the medical service person being on duty in ward.

The purpose of this study was to investigate spatial characteristics and using behavior of activity room in skilled nursing facilities for the elderly and to provide basic guidelines about its space planning. The activity rooms in the most of the research facilities were arranged by usage modification of unnecessary spaces after the foundation of the facility, and were used not only for the program service but for the staff lounge. It decreased space speciality and resulted in limited area of the space and crowded furniture arrangement. The design guidelines for activity room were as follows. First, the space plan of activity room is based on the use of once to twice per week and for 30 minutes per use, and is mainly for the human knowledge and art programs that are appropriate for small group. Second, the activity room of the facility with less than 3 stories needs to be in the same floor as elderly individual room, but should be independent and easy to be controlled by the staff. On the other hand, in more than 4 stories facility, it is better to be in the different floor as the elderly living area such as administrational area close to the lounge and garden. Third, at least $5.9m^{2}$ per user for the area of the activity room is recommended including the elderly, staff, furniture, equipments and restroom. Fourth, the furniture of activity room includes the shelves, big table with enough knee space, wheel, and stopper, and stackable chairs. Toilets and water closet are needed for the emergency, and the windows to the corridor and curtain door should be avoided for soundproof and easy access of wheelchair users.

As the number of CFRD constructions increases, the necessity of an accurate assessment on its behavior also has been increasing accordingly. The performance of concrete faced rockfill dam (CFRD) under different water levels is greatly concerned by dam engineers and designers in the world. However, domestic research on CFRD design and construction has yet been insignificant. This study deals with three centrifuge model tests, mainly investigates the deformation of the concrete faced slabs with different face slab stiffness under different water levels. The prototype of a centrifugal model dam is half size of domestic CFRD dam. Detailed material preparation, model design, model set-up, model instrumentation and testing procedures are presented. In order to simulate the prototype concrete faced slab, three kinds of thin fiberglass plates with different thickness was adopted in the three model tests. The water level control facility was specially designed for this experiment to control the water level rise and drawdown during centrifuge flight. Although most of the results from the three model tests are satisfactory, it is also required that the centrifuge test results should be compared with those of numerical analysis and field measurements to analyze the centrifuge test results more in detail.

In this study, the large scale test was performed to investigate the behavior of failure on the embankment and spillway transitional zone by overtopping. The pore water pressure, earth pressure, settlement and failure behaviors according to several reinforcing method were compared and analyzed. The pore water pressure showed a small change in the spillway transition zone and core, indicating that the riprap and geotextile efficiently reinforced the embankment, but non-reinforcement showed a largely change in pore water pressure. The earth pressure by riprap and geotextile at upstream slope and bottom core increased rapidly with the infiltration of the pore water by overtopping. And the earth pressure at crest showed a smally change due to effect of the inclined core. A settlement by riprap showed a small change and the geotextile decreased a rapidly due to failure of crest. The width of failure by riprap at intermediate stage (50 min) showed a largely due to sliding of crest. But, the width and depth of the seepage erosion after the intermediate overtopping period (100 min) were very small due to the effect of riprap than geotextile and non-reinforcement which delayed failure. It has the effect that protect reservoir embankment from erosion in the central part. The pore water pressure at the spillway transition zone due to overtopping increased a rapidly in the case of non-reinforcement, but the reinforced methods by geotextile and riprap showed a smally change. Therefore, the reinforced method by riprap and geotextile was a very effective method to protect permanently and the emergency an embankment due to overtopping, respectively.

Background : In order to improve the quality of life of dying patients, they need to receive not only the physical, psychological, social, and spiritual care, but also systematic and continuous care to die with dignity. However, no adequate medical services are available for these terminal cancer patients. We studied their behavior patterns of health care utilization to understand more of their medical and social needs. Methods : We investigated 108 bereaved families through the telephone interview with structured questionnaires. They were randomly selected through the retrospective chart review of the terminal patients who passed away due to cancer. Results : Most of the terminal cancer patients received their care from proper medical services including admission to hospital (45.4%), outpatient clinic (22.2%), emergency room (16.7%), and oriental medicine (12.0%). But during the terminal phase of their illness, 32.4% of patients never received medical care including oriental medicine, and 28.7% received alterative natural care. 26 bereaved families (24.1%) pointed out the indifference of medical staff as a problem receiving proper hospital care, and 22 (20.4%) emphasized emotional strain of their helplessness with the patients' suffering as a problem of caring at home. Over 90% suggested availability of continuous care, hospice care, home care, and 24 hour telephone service to be improved. Conclusions : Due to various reasons, adequate medical care is not delivered to the terminal cancer patients in our present medical system. These problems can be approached with the establishment of proper education and medical delivery system. The role of comprehensive medical specialty cannot be overly emphasized to accomplish this most effectively.
