The Medical Affairs Law regulates that Medical Doctor and Korean Medical Doctor(KMD) can practice in the boundary of each licence. But there is no clear provision to explain what practice in the boundary of MD's permitted region and what is KMD's. Moreover practice over the boundary of licence could be punished as a violation of the Law. KMD's use of medical devices have been objects of legal conflicts in the field. Because there is no clear provision in the Law, judical precedents have played the role as practical and final regulations. In this study, analyses on some judical precedents could show some rationales whether an issued KMD's use of medical devices is in the boundary of license. The courts considered the theories based on the practice, the level of required specialty and education, and the probability of danger to a patient. The judical precedents should be reviewed more precisely in the respects that it is adaptable in "the written law system"and it is desirable to divide boundaries between MD's and KMD's.

The ambulance service time interval, in particular the response time, has been used as an important indicator for the quality control of ambulance services in that it can be improved to increase the probability of survival and decrease the sequela-related disability. Based on the 2011~2014 Prehospital Care Reports in a metropolitan city, this study analyzed the time interval of ambulance services considering the patient's characteristics and chief complaints. If the definition of the time of ambulance services can be refined further, and a variety of economic and social factors and local characteristics would can be analyzed, the quality of the ambulance service is expected to be enhanced significantly.

The principal measure of housing demand is income and the preferences expressed by households through their respective indifference curves. In this context, housing essentially becomes a derived demand, i.e., the household consumes land and a location (or distance-in time and money costs), according to its relative preferences for space, accessibility, and all other nonhousing goods. This paper attempts to deal with both aspects of housing (apartment) demand and household mobility in the Seoul Metropolitan Areas. Housing services will be measured using hedonic regression technique. From observations on the market prices of dwelling units and on the underlying characteristics of housing, one can estimte the relationships between the two empirically. In predicting the probability of the future moves into new towns in the Seoul Metropolitan areas, the best predictors of the future moves into new best predictors are found to be the degree of satisfaction not only with the current residence as a whole, but with some of the major amenities, accessibility and child education. The reasons for moving into new towns are diverse depending on the households' current situation; the most frequently cited is "improvement of housing conditions," followed by "improvement of living environment," "asset improvement" and "home ownership". It appears that people move houses because of a dissatisfaction with their current housing status, relative their income or needs, or a desire to improve their housing and neighborhood amenities, or both. On the other hand, it is clear that the development of new towns in the Seoul Metropolitan Areas should be based on the analysis of housing demand and the pattern of household mobility in Seoul housing market.sehold mobility in Seoul housing market.

Objectives : The purpose of this study was to attempt to lay the foundation for the development of oral health programs geared toward promoting the oral health of low socioeconomic class children. Methods : The subjects of this study have been investigated for the use of children to 96 local children's center. Questionnaire for research purposes are described in more detail under the coordination of child care teachers to students, students to be able to record. The survey was conducted at the Health center. Analyzed the data collected by SPSS 18.0. Results : The findings of the study were as follows: The children were influenced by habits of having a snack in dental caries experience. Higher intake of bread and a lot of children more probability of dental caries experience. I've found a lot of sweet-food intake eleven cakes or fruits and vegetables that children prefer higher dental caries experience was low. Conclusions : Education on dietary behavior for low-income children was necessary because of the high correlation of the relationship between dietary habits and dental caries and diet.

Changes of phycobiliproteins(PBP) quantity and ferredoxin-NADP reductase(FNR) activity were investigated in various light illuminated cyanobacteria, Anabaena variabilis. PBP components were increased under blue light illumination, whereas decreased under red light illumination. PBP contents were twofolds in blue light than in red light. In view of the PBP composition, allophycocyanin(APC) in red light was higher 5.5% and phycoerythrocyanin(PEC) in blue light was higher 2.2% than in white light-illuminated PBP. It was suggested that PBP changes in bule light be the results of regulation of photosysthetic efficiency and protection of photosystem, whereas PBP changes in red light be effected by adaptation of adequate harvesting of light energy in photosystem. Changes of FNR activity were highest in red light, and sequenced lower to blue light and green light. It means that light-dependent production rate of NADP is the highest in red light. The difference of values was larger than that of values in comparison of red and blue light. It was suggested that increasing of FNR activity be due not to the function of isozyme, but to the synthesis of enzymes. Because of NAD/NADP regulation-effect to metabolism, it was considered that FNR activity might influence the metabolism indirectly and explain the probability of regulation in pathways of key enzyme activation. FNR activity was directly proportional to intensity of light. Optimum temperature and pH were about 25℃ and 7.5, respectively.

This study investigates the factors affecting Industry 4.0 adoption in the curriculum of university students in Ho Chi Minh City, Vietnam. Universities need to respond to the changing faces of Industry 4.0 and, hence, Education 4.0. A mixed method including both qualitative and quantitative methodologies was utilized. An in-depth interview was carried out for exploring, reviewing, and testing content validity of constructs and measurement items. The pilot study was conducted with 120 respondents. The conceptual model and hypotheses were developed using data collected by a questionnaire survey distributed to 584 respondents by both electronic and paper forms with non-probability and convenience sampling techniques. The result of structural equation modeling showed that occupation relevance, skills, facility conditions, and social influence impacted on the intermediates variables, namely, relevance advantage, perceived usefulness, behavioral intention-to-use, and actual use. The independent variables are occupation relevance, skills, facility conditions, and social influence. They impact actual use through mediating constructs such as relevance advantage, perceived usefulness, and behavioral intention-to-use. The findings suggest that universities and students' efforts aimed at increasing the factors' perceptions of adoption of Industry 4.0 will contribute to implementation success, where success is defined as effectual usage of Industry 4.0.

Given the yield shear of a single-story inelastic structure with simple eccentricity, the problem of strength distribution among the resisting elements is investigated, with respect to minimize its torsional response during a ground motion. Making the hypothesis that the peak accelerations, of both modes of vibration, are determined from the inelastic acceleration spectrum, and assuming further that a peak response quantity is obtained by an appropriate combination rule (square root of sum of squares-SRSS or complete quadratic combination-CQC), the first aim of this study is to present an interaction relationship between the yield shear and the maximum torque that may be developed in such systems. It is shown that this torque may be developed, with equal probability, in both directions (clockwise and anticlockwise), but as it is not concurrent with the yield shear, a rational design should be based on a combination of the yield shear with a fraction of the peak torque. The second aim is to examine the response of such model structures under characteristic ground motions. These models provide a rather small peak rotation and code provisions that are based on such principles (NBCC-1995, UBC-1994, EAK-2000, NZS-1992) are superiors to EC8 (1993) and to systems with a stiffness proportional strength distribution.

This study analyzed the data from Korea National Health and Nutrition Examination Survey to examine factors associated with help-seeking among Korean adults with suicidal ideation. The results from binary logistic regression analysis showed that being currently married, low family income, and absence of diagnosed clinical depression were negatively associated with seeking help. Gender, age, education, the PHQ total score, and health insurance did not significantly change the probability of seeking help. The future suicide help-seeking intervention should focus on those who are less likely to seek help.
