This study was conducted to identify the subjective damage caused by COVID-19 and its related factors. The study subjects were members of the Korean Dental Association (KDA). We investigated the damage to dental clinics and hospitals caused by COVID-19 between January and April 2020. After analyzing the final 3,189 responses, the rate of decrease in patients was the highest at 34.9% in March, and the rate of decrease in income was the highest at 34.0% in April. As a result of the multilevel analysis, the damage caused by COVID-19 was greater in regions with more confirmed patients, more careers, and fewer dental staff. The government should establish a compensation plan for hospitals and clinics to prevent the collapse of the medical system due to the prolonged COVID-19. In addition, support for dentistry should be provided to maintain the oral health care system in the future.

Purpose. The purposes of this study were to develop a PBL program for continuing nurse education and to evaluate the program after its implementation. Methods. The PBL program was developed in the core cardio-pulmonary nursing concepts through a collaborative approach with a nursing school and a hospital. The PBL packages with simulation on ACLS were implemented to 40 clinical nurses. The entire PBL program consisted of six 3-hour weekly classes and was evaluated by the participants' subjective responses. Results. Two PBL packages in cardio-pulmonary system including clinical cases and tutorial guidelines were developed. The 57.5 % of the participants responded positively about the use of PBL as continuing nurse education in terms of self-motivated and cooperative learning, whereas 20.0% of the participants answered that the PBL method was not suitable for clinical nurses. Some modifications were suggested in grouping participants and program contents for PBL. Conclusion. The PBL method could be utilized to promote nurses' clinical competencies as well as self-learning abilities. Further research is needed in the implementation strategies of PBL-based continuing education in order to improve its effectiveness.

SoC(System on Chip)는 버스 아키텍처 안에 여러 개의 마스터, 슬레이브, 아비터 그리고 디코더로 구성되어 있다. 마스터는 CPU, DMA, DSP 둥과 같이 데이터 트랜잭션을 발생시키는 블록이고, 슬레이브는 SRAM, SDRAM, 레지스터 등과 같이 데이터 트랜잭션에 응답하는 블록이다. 또한 아비터는 마스터가 동시간대에 버스를 이용할 수 없기 때문에 이를 중재하는 역할을 수행하는데, 어떠한 중재 방식을 선택하는가에 따라 SoC의 성능이 크게 바뀔 수 있다. 일반적인 중재 방식에는 fixed priority 방식, round-robin 방식, TDM 중재 방식 등이 있다 본 논문에서는 TLM 알고리즘을 구성하여 일반적인 중재방식을 TLM 시뮬레이션을 통해 비교 분석하였다. 또한 새로운 중재 방식인 하이브리드 버스 중재 방식을 제안하고 다른 중재 방식과 비교하여 성능을 검증하였다.

Conducted as an ethnographic examination of science teaching and learning in an Innovative Middle School in Korea, this study employs sociocultural theory to examine how structures afford and limit student participation in an innovative school designed to promote student-centered learning. Data includes teacher and student interviews, student responses to a questionnaire, classroom observations, and analysis of video recordings of ten lessons in two in two 8th grade science classes. Using structure|agency dialectic theory, we identify and describe some structures that afford and limit teacher and student agency at the micro (science classrooms), meso (school), and macro (Korean society) levels to raise some questions about current reform measures, such as innovation schools, that seek to position classroom teachers as agents for change in science education reform in Korea. Findings suggest that while teachers and school administrators play an essential role in structuring learning opportunities at the meso and micro levels, they have limited agency to address structural constraints originating at the macro-level, which can negatively impact teaching and learning in the science classroom. We offer implications for policy and practice and argue the need for more qualitative research, informed by sociocultural theory, to inform science education reform efforts in Korea.

The Chicago-Bermuda system has been charaterizing international aviation order sine 1940's. Bilateralism was established as 'the' way of nogotiation in exchange of traffic rights among nations thanks to the system. The system was stable until new phenomena came into the scene. The orderly development of international aviation began to be threatened by a series of technological and commercial breakthroughs in the late 60's and 70's. Also, in the field of international aviation, aspiration of the newemerging third world countries was hightened and the emergence of an unified Europe was added to it. These caused worries on bilateralism as an efficient means of negotiation. New waves of multilateral(reginal or international) approaches have been conducted. Its formal discussion is accelerated by vigorous talk on multilateral liberalization of international trade in commodities and services, i.e., the Urguay Round. In this paper, we examine historical development of bilateralism and multilateralism in a perspective of political economy; changes in the international aviation industry, merits and demerits of the two regimes on competitiveness of negotiating partners. The ways Korea can respond to new changes are presented and compared and a tentative stance she can take is proposed.

Objectives : This study was to determine how the perception and the satisfaction of outpatients who utilized clinics and hospitals are structurally related with their willingness to utilize the same institution in the future. Methods : Three hundred and ten responses (via convenient sampling) were collected from 5 hospitals and 20 clinics located in Seoul listed in the "Korea National Hospital Directory 2005". Service quality was utilized as the satisfaction measurement tool. For analysis, we used a structural equation modeling method. Results : The determining factors for general satisfaction with medical services are as follows: medical staff, reasonability of payment, comfort and accessibility. Such results may involve increased competition in the medical market and increased demands for quality medical services, which drive the patients to visit hospitals on their own on the basis of changed determining factors for satisfaction. Conclusions : The structural equation model showed that the satisfaction of outpatients with the quality of medical services is influenced by a few sub-dimensional satisfaction factors. Among these sub-dimensional satisfaction factors, the satisfaction with medical staff and payment were determined to exert a significant effect on overall satisfaction with the quality of medical services. The structural relationship in which overall satisfaction perceived by patients significantly influences their willingness to use the same institution in the future was also verified.

There is general consensus in the research literature that market orientation is related to organizational performance. The study examines this relationship in the Korean hospital industry. One feature of this study is to examine the differences between large and small hospitals in terms of their market orientation, performance and the relationship between these constructs. The other feature is that both market orientation and performance are conceptualized as being multi-dimensional constructs. Hence a structural equations modeling (SEM) technique is used to examine the dimensionality of market orientation and performance and to examine the nature of this relationship. Data for this study are collected using a questionnaire that is mailed to the top marketing-related managers of 1,048 hospitals. Usable responses are obtained from 230 hospitals for a response rate of 21.9%. The SEM results confirm the multi-dimensional nature of both market orientation and performance, and the strong relationships between the constructs. Interestingly, this relationship is found to be much stronger for smaller hospitals than for larger hospitals. For smaller hospitals, this study shows that market orientation has a tremendous influence on performance, with almost 73.9% of the variance in performance being attributed to market orientation.

Background: Happiness is one of the most important indicators of health, wellbeing, and quality of life among older adults. The objective of the study was to investigate factors associated with happiness among senior citizens residing in rural areas using the 2017 National Survey of Older Koreans. Methods: A cross-sectional analytical study was conducted among 3,149 senior citizens living in rural areas using secondary data from the 2017 National Survey of Older Koreans. Happiness was measured by a single question and responses were recorded dichotomously. Descriptive and inferential statistics were computed at a 5% level of significance. Results: In all, 64.5% of the participants considered themselves as happy most of the time in the last 1 week. In the study, socio-demographic factors did not predict happiness except age. Satisfaction with a health status, financial situation, relationship with children, cultural satisfaction, and satisfaction with friends and society were positively associated with happiness among senior citizens residing in rural areas of Korea. Odds of reporting happiness were higher among those who traveled in the last 1 year, visited elderly welfare centers, and were involved in voluntary work than among those who did not. Conclusion: Happiness among senior citizen was significantly associated with life satisfaction with regard to health, finance, relationship with family, friends and society, and social activity participation.

As the competition among hospitals become intensified, hospital management is required to carry out more effective marketing and positioning of the hospital. Successful positioning of a hospital requires the knowledge about how the concrete attributes inherent in the medical service associated with the customer values that customers seek eventually in the medical service. Thus, it is required for hospital management to understand which hospital attributes should be emphasized in order to improve the customer values. The hierarchical structure of service attributes can provide valuable information about effective positioning and advertising. To obtain such knowledge, we employed the order analysis technique as an objective means-end chain method. Order analysis is useful for identifying the causal structure among attributes. Thus, we can examine the underlying causal relationship and eventually the vertical structure of hospital selection attributes. For this study, we conducted a survey to obtain 370 responses for the analysis. The result suggests that hospital management had better increase the scale of hospital, improve the services of health care providers, and modernize the hospital facilities and equipments so as to enhance customer values and eventually to lead them to recommend the hospital to others. Our findings would provide the valuable information for hospital management to develop the more effective hospital positioning and marketing strategies.
