Radiological Technologists deals with the life of a person which means professional competency is essential for the job. Nevertheless, there have been no studies in Korea that identified the job competence of radiologists. In order to define the core job competencies of Korean radiologists and to present the factor models, 147 questionnaires on job competency of radiology were analyzed using 'PASW Statistics Version 18.0' and 'AMOS Version 18.0'. The valid model consisted of five core job competencies ('Patient management', 'Health and safety', 'Operation of equipment', 'Procedures and management') and 17 sub - competencies. As a result of the factor analysis, the RMSEA value was 0.1 and the CFI, and TLI values were close to 0.9 in the measurement model of the five core job competencies. The validity analysis showed that the mean variance extraction was 0.5 or more and the conceptual reliability value was 0.7 or more, And there was a high correlation between subordinate competencies included in each subordinate competencies. The results of this study are expected to provide specific information necessary for the training and management of human resources centered on competence by clearly showing the job competence required for radiologists in Korea's health environment.

Social medicine is recognized as one of medical specialties in many countries. However, social medicine has never been formally introduced to Korea, presumably because the term and its principles were not accepted for some years in the past in American medicine, which has strongly influenced Korean medicine. This paper describes the origins and evolution of social medicine and briefly discusses contemporary social medicine in Korea. Social medicine was initiated in France and Germany in 1848. Since then, it has expanded globally and developed in diverse ways. Included in core principles of social medicine is that social and economic conditions have important effects on health and disease, and that these relationships must be subjected to scientific investigation. The term 'social medicine' is rarely used in Korea, but many of its subject matters are incorporated into preventive medicine which, besides prevention, deals with population health that is inescapably social. However, the Korean preventive medicine directs little attention to the basic concepts and principles of social medicine, upon which systematic development of social medicine can be based. Thus, it is necessary to supplement the social medicine contents of preventive medicine through formalizing the linkages between the two fields. One way of doing so would be to change the title of 'preventive medicine' course in medical colleges to 'preventive and social medicine,' as in many other countries, and to adjust the course contents accordingly.

Purpose: To provide practical data for bioethics education, we identified correlations between recognition of good death, attitude towards withdrawal of meaningless life-sustaining treatment, and attitude towards euthanasia in nurses. Methods: Using convenience sampling, we recruited 218 nurses who had at least six-month work experience in one of the six general hospitals with 500 or more beds in Seoul, Busan, and Gyeongsang province. All participants understood the purpose of the study and agreed to take part in the study. The research tools used included the Concept of Good Death Measure (CoGD), the measurement tool for attitudes towards withdrawal of meaningless life-sustaining treatment (WoMLST), and the measurement tool for attitudes towards euthanasia. Data were analyzed using an Independent t-test, one-way ANOVA, and Pearson's correlation coefficient using SPSS 21 for Windows. Results: Nurses had normal levels on CoGD, WoMLST, and attitudes towards euthanasia. Nurses' CoGD, WoMLST, and euthanasia scores significantly differed depending on their education level, working period, and the importance of religion to them. A negative correlation was found between the CoGD and WoMLST scores, and WoMLST and euthanasia scores were positively correlated. Conclusion: Nurses should be trained to deal with ethical issues that may arise while caring for terminal patients. It is necessary for nurses to understand the concepts related to CoGD, WoMLST, and euthanasia, and to promote bioethics education with focus on decision-making and problem-solving ability in ethically conflicting situations.

Background and Aim : Lately the age of competition has come among the medical service area. At the same time disputes over the medical practice related to the medical person's territory tend to increase. In part it is due to the increased medical persons but in part it is because the medical practice is not defined clearly in the Medical Service Act for the practice of each medical person. So the legal definition of medical practice will be discussed here. Materials and Method : The cases from the court have been confirmed the difference between the two medical persons regarding the actual events. Legal aspects of medical practice in Korean medicine and the related cases will be reviewed and analysed. Results : The form of medical practice consists of administrating Korean medicine treatment and providing guidance for health based on Korean medicine. For medical doctors the practice includes medical treatment and guidance for health. Circular definition in the Medical Service Act over the medical practice, medical person and medical instruments makes it difficult to understand the whole idea. Therefore, the court has a tendency to decide the medical practice of medical doctor of Korean medicine from the some reliable points which is: 1) it is based on the principle of traditional Korean Medicine, 2) it is practiced by the medical doctor of Korean Medicine, 3) it can do harm to the patient without proper involvement of the medical doctor of Korean Medicine. Now the Act on the promotion of Korean Medicine and Pharmaceuticals makes it include the concept of "scientifically applied and developed" medical practice of Korean Medicine. Conclusions : With the essential change in the Act on the promotion of Korean Medicine and Pharmaceuticals, it is expected that even slight change can be seen in the court cases. However, still the concept of medical practice in the Medical Service Act remains the same. Modernisation of Korean Medicine, enhancement of textbooks and clinical practice training and the effort to amend the law to clearly define the medical practice of Korean Medicine will contribute to the clinical and academic environment. Evidence based Korean Medicine and even the unification of east-west medicine could be considered for the situation.

In 1895, the discovered X-ray is used for not only in this field of medicine wide but also field. The detection of radiation after, people realized the risk of the radiation exposured recommended the principle about the protection of radiation by the part of the effort for lowering the radiation exposure. In this recommendation, all unnecessary radiation exposure have to be prevented by All doses include the protection of radiation, general idea of applicable two kinds of that it has to low maintain. Presently, in the General X-ray room of the clinical, the lead (Pb) was used for the shielding, However, because it had the problem of the lead poisoning which is fatal in the human body, the alternatives was showed. and Among them, the material that it is the tungsten was presented. in this research, the absorbed spectrum according to the thickness in the continuous X-ray energy of the tungsten which is not harmful to the human body through the Monte Carlo simulation, tried to compare with the absorbed spectrum of the lead (Pb). The tungsten confirmed that simulation presumption than result lead in the whole domain that absorbed probability was higher and it is considered that tungsten shows the absorbed efficiency higher than the lead in particularly, 70 keV ~ 90 keV and the tungsten is more useful to the X-ray energy cover of the high energy diagnostic area.

As medical practices and procedures become more specialized and information technology develops in clinical settings, health organizations need medical personnel with special skills, knowledge and competency. But the lack of practical experience in clinical settings may impair competency in basic nursing skills among nursing students. This study used a cross-sectional survey to analyze factors related to nursing competency among nursing students in order to establish effective teaching methods to increase the clinical competency of nursing students. The data were collected from a questionnaire distributed in several universities among 106 nursing students who expressed a willingness to participate in the study during December 2011 in order to measure self-directedness, professional self-concepts, communication ability, learning satisfaction. The data were analyzed using the SPSS window program. There were differences regarding competency in basic nursing skills according to interpersonal relationships, grades, existence of an open lab. The level of learning satisfaction, communication skills and self-directedness were deemed influencing factors regarding competency in basic nursing skills. These 3 elements account for 49.9% of competency with regard to basic nursing skills. According to existing research, blended learning methods which consist of problem based learning, cyber education or case centered education should be considered as effective teaching methods for developing clinical nursing skills.

The results of this study are the two. First, for convergence technology and convergence technology transfer based on analysis of previous studies I suggested a framework for convergence-type technology transfer conceptualization and measurement. Second, I am compared convergence-type technology transfer to total technology transfer from public research(university and public institute) to SME. Overall, despite the trend to increase technology transfer to SMEs, convergence-type technology transfer is only 4.4%. Both total technology transfer and convergence-type technology transfer to the Industry is active to electronic components, machinery, chemicals, food and beverage, and the medical. The role of universities is emphasized in both total technology transfer and convergence-type technology transfer. There are small transactions of less than 5 million in both total technology transfer and convergence-type technology transfer. Both total technology transfer and convergence-type technology transfer to the region are concentrated in Seoul, Daejeon and Gyeonggi-do.

Scientific community agrees about the fact that base Isolation provides interesting solutions to minimize the seismic risk. Reliability of such a technique is nowadays proofed by a large number of applications like public buildings, nuclear plants, bridges, etc. This paper reports the results of performance verification tests of the base isolated RC building with the laminated rubber bearings which is manufactured by enterprise in Korea. The shaking table tests were performed using a three story model scaled to 1/3 of the prototype RC apartment building. Several major earthquake records were scaled to different peak ground accelerations and used as input base excitations. Especially in this study, effect of earthquake characteristics on response reduction and effect of the intensity of excitations are studied. Through the verification tests, the validity of the applied base isolaion device and the response reduction effect against earthquakes are confirmed.

This study is based on the theory of salutogenesis, and investigates factors affecting the health status of radiologists who experience high stress and health problems in the rapidly changing medical environment. The study enrolled 379 radiologists working at hospitals in Daegu. A health structure model was established by applying the theory of salutogenesis. Sense of coherence had a direct effect on the health status of radiologists. Psychological stress, social support, and drinking were also influential factors, due to their mediating effect on the sense of coherence. Moreover, social support was also found to be lower when job stresses were higher. Hence, increased psychological stress resulted in lower levels of sense of coherence, social support and exercise. Taken together, results of this study indicate that effects on the sense of coherence have maximum influence on the health status of radiologists, and social support among general resistance resources is an important factor for enhancing sense of coherence. In addition to social support and health behaviors, researches involving various resources and the development of organizational strategies and health promotion intervention programs are required in future, to enable radiologists to cope with their stresses and improve health.

Mobile healthcare is a fusion of information technology and biotechnology and is a new type of health management service to keep people's health at anytime and anywhere without regard to time and space. The WBAN(Wireless Body Area Network) technology that collects bio signals and the data analysis and monitoring technology using mobile devices are essential for serving mobile healthcare. WBAN consisting of users with mobile devices meet another WBAN during movement, WBANs transmit data to the other media. Because of WBAN conflict, several nodes transmit data in same time slot so a collision will occur, resulting in the data transmission being failed and need more energy for re-transmission. In this thesis, we proposed a MAC protocol for WBAN with mobility to solve these problems. First, we proposed a superframe structure for WBAN. The proposed superframe consists of a TDMA(Time Division Muliple Access) based contention access phase with which a node can transmit data in its own time slot and a contention phase using CSMA/CA algorithm. Second, we proposed a network merging algorithm for conflicting WBAN based on the proposed MAC protocol. When a WBAN with mobility conflicts with other WBAN, data frame collision is reduced through network reestablishment. Simulations are performed using a Castalia based on the OMNeT++ network simulation framework to estimate the performance of the proposed superframe and algorithms. We estimated the performance of WBAN based on the proposed MAC protocol by comparing the performance of the WBAN based on IEEE 802.15.6. Performance evaluation results show that the packet transmission success rate and energy efficiency are improved by reducing the probability of collision using the proposed MAC protocol.
