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 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.

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.

일반적인 CHMM 어휘 인식 시스템은 어휘 인식에 대한 모델들의 관측 확률 인식률이 낮고, 일부 단위 음소 모델에만 적용되어 제한적으로 사용되는 문제점이 있다. 또한, 어휘 탐색에서 어휘의 의미가 다양하여 탐색된 어휘가 사용자의 요구에 부합되지 않는 문제점을 가진다. 이러한 문제를 개선하기 위해 GMM(Gaussian Mixture Model)을 이용한 음소인식을 수행하고, 개선된 k-means 알고리즘을 이용하여 어휘 특성에 따른 제한적인 탐색 문제점을 해결하였다. 성능 실험은 기존의 시스템과 비교하여 정확도와 재현율로 대변되는 효과성을 측정하였으며, 성능 실험 결과 정확도는 83%, 재현율은 67%로 나타났다.

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.

영재아들을 대상으로 한 수업에서 모호성을 적극적으로 강조하였을 때, 영재아들이 모호성에 어떻게 대처하는지, 모호성을 해소하기 위해 어떠한 방식을 선택하는지, 구체적으로 모호성이 이들의 수학적 정당화와 관점전환 활동에 어떠한 영향을 미치는지 알아보았다. 모호성은 당연한 것을 의문시하고 수학적 정당화의 필요성을 의식하는데 도움이 되었으며, 특히 서로 경쟁하는 관점을 비교하면서 학생들은 유연한 관점전환을 경험하고 이 통해 자신의 수학적 지식을 검증하고 강화하는 기회를 가질 수 있었다. 자신의 관점에서 깨닫지 못했던 새로운 기회와 가능성을 다른 관점과의 소통을 통해 발견하였다. 영재아들은 모호성을 해소하는 과정에서 두 관점 사이의 관계를 형성하면서 유연한 관점 전환이 가능해지고 결국 일반적이고 통합된 수학적 지식을 구성하였다.

본 연구는 국민건강영양조사 자료를 활용하여 자살생각이 있는 우리나라 성인의 도움추구에 영향을 미치는 요인을 분석하였다. 지난 2주간 자살생각을 경험한 만 19세 이상 성인을 조사대상으로 하였으며 이들이 우울증상과 관련하여 상담이나 도움을 요청하였는지의 여부에 영향을 미치는 선행요인, 욕구요인, 가능요인들을 알아보는 이항 로지스틱 회귀분석을 실시하였다. 분석결과 기혼자, 가구소득이 낮은 사람, 그리고 예전에 우울증 진단을 받은 적이 없는 사람은 도움추구를 할 가능성이 낮은 것으로 나타났다. 성별, 나이, 교육수준, PHQ-9 총점, 거주지, 건강보험은 통계적으로 유의미한 결과를 나타내지 않았다. 이를 바탕으로 도움추구 증진을 통한 자살예방을 위해서 저소득계층, 예전에 관련 의료체계를 이용한 경험이 없는 사람들, 비공식적 도움을 선호하는 사람들에 대한 의료 및 상담 체계 접근성 향상이 필요함을 제안한다.
