Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has placed unprecedented pressure on healthcare systems, even in advanced economies. While the number of cases of SARS-CoV-2 in Africa compared to other continents has so far been low, there are concerns about under-reporting, inadequate diagnostic tools, and insufficient treatment facilities. Moreover, proactiveness on the part of African governments has been under scrutiny. For instance, issues have emerged regarding the responsiveness of African countries in closing international borders to limit trans-continental transmission of the virus. Overdependence on imported products and outsourced services could have contributed to African governments' hesitation to shut down international air and seaports. In this era of emerging and re-emerging pathogens, we recommend that African nations should consider self-sufficiency in the health sector as an urgent priority, as this will not be the last outbreak to occur. In addition to the Regional Disease Surveillance Systems Enhancement fund (US$600 million) provided by the World Bank for strengthening health systems and disease surveillance, each country should further establish an epidemic emergency fund for epidemic preparedness and response. We also recommend that epidemic surveillance units should create a secure database of previous and ongoing pandemics in terms of aetiology, spread, and treatment, as well as financial management records. Strategic collection and analysis of data should also be a central focus of these units to facilitate studies of disease trends and to estimate the scale of requirements in preparation and response to any future pandemic or epidemic.

의료 이미지는 사람 신체의 비정상적인 상태를 발견하는데 효과적인 자료로 사용되고 있다. 일반적으로 환자는 다양한 이유로 다른 종류의 의료 기관을 방문하고, 심각한 질병 특징을 가지는 의료 이미지에 대해 2차 소견을 얻기를 원한다. 현재에는 개인의 의료 이미지가 여러 의료 기관에 산재되어 있기 때문에, 2차 소견을 얻을 때 자신과 관련된 모든 정보를 직접 가지고 다른 의료진을 찾아가야 하는 불편함이 있다. 이런 두 가지 동기로 인해, 본 논문에서는 의료 이미지 보관 및 판독 서비스를 제안하고자 한다. 그러므로, 의료 이미지 보관 및 판독 서비스의 설계 모델 및 구현 결과를 본 논문에서 제시하고, 저비용 개인 헬스케어 서비스로서의 실용적 가치를 증명하고자 한다. 환자는 제안하는 서비스를 사용함으로써 언제든 자신의 의료 이미지 정보를 확인할 수 있고 의료진을 찾아갈 필요 없이 간편하게 의료 이미지 분석을 할 수 있다.

Expenditures on pharmaceuticals of different concepts were estimated and their functional, financing and providers' breakdowns were examined in line with the OECD's System of Health Accounts (SHA) manual. This study also shows the way such estimates are made. The results are then analyzed particularly from the international perspective. Data from both Household Survey by the National Statistical Office and the National Health and Nutritional Survey by the Ministry of Health and Welfare of Korea were used to estimate pharmaceutical expenditures that. are financed by out-of-pocket payments of the household, while national health insurance data etc. were used for estimation of pharmaceutical expenditures that are financed by public funding sources. The 'per capita expenditure on pharmaceutical/medical non-durables' in Korea stood at 380 US$ PPPs, less than the OECD average of 443 US$ PPPs in 2006, but its share of the per capita health expenditure of 25.9% noticeably outnumbered the OECD average of 17.1%, due partly to low per capita health expenditure as a denominator of the ratio. This indicates that Koreans tend to spend less on health care than an OECD average, while tending to spend more on pharmaceuticals than on other health care services, much like the pattern found in relatively low income countries. An international pharmaceuticals pricing mechanism is most likely responsible for such a tendency. In addition, it is to be noted that the percentage comes down to 21.0%, when expenditures on both medical non-durables and herbal medicine, which is locally quite popular among the elderly, have been excluded.

Objectives : This study examined the health policy researchers' needs and their accessibility towards health insurance claim datasets according to their academic capacity. Methods : An online questionnaire to capture relevant proxy variables for academic needs, accessibility, and research capacity was constructed based on previous studies. The survey was delivered to active health policy researchers through three major scholarly associations in South Korea. Seven-hundred and one scholars responded while the survey as open for 12 days (starting on December 20th, 2010). Descriptive statistics and logistic regression analysis were carried out. Results : Regardless of the definition for operational needs, the prevalent needs of survey respondents were not met with the current provision of claim data. Greater research capacity was shown to be correlated with increased demand for claim data along with a positive correlation between attempts to obtain claim datasets and research capacity. A greater research capacity, however, was not necessarily correlated with better accessibility to the claim data. Conclusions : The substantial unmet need for claim data among the healthcare policy research community calls for establishing proactive institutions which could systematically prepare and make available public datasets and provide call-in services to facilitate proper handling of data.

사상의학에서는 사람을 네 종류로 구분하며, 한의사들은 종종 이 네 종류에 기반을 두어 특별한 건강 정보와 치료 방법을 제안한다. 얼굴의 특징 비율(표 1)은 사상체질을 판단하는데 있어서 매우 중요한 기준으로 사용되는데, 본 논문에서는 측면얼굴에서 특징 비율을 추출하기 위한 시스템을 제안하였다. 특징 비율을 얻기 위해서는 두 가지를 고려하여야 한다. 하나는 대표 특징들을 선택하는 것이고, 다른 하나는 측면 얼굴 이미지에서 효과적으로 관심 영역을 검출하고, 정확하게 특징 비율을 계산하는 것이다. 논 논문에서 제시한 시스템에서는 적응형 색상 모델을 사용하여 배경에서 측면 얼굴을 분리하였고, 관심 영역 검출을 위해서 기하 모델에 기반한 방법이 사용되었다. 또한 이미지 크기와 머리 포즈에 따른 이미지 변화에 의해서 야기되는 에러 분석을 제시하였다. 제시한 시스템의 성능을 평가하기 위하여 173명의 한국인 왼쪽 얼굴 사진을 이용하여 시스템을 테스트하였고, 정면 사진과 측면 사진을 함께 사용하였을 경우 정면 사진만을 사용한 경우보다 17.99%의 성능 향상을 나타내었다.

It is a daunting task to theorize the process effectiveness of IT convergence based service model. Despite the criticalness of investigating process enhancement impact of IT-convergence based service model, the theoretical research in this field is relatively scarce, possibly due to the too wide and comprehensiveness of research scope. In this vein, we conducted exploratory study to understand the contributional impact of IT convergence based service model on resolving service process limitations. We first identified five IT convergence based service models in the area of typical service industry, which include entertainment, learning, location based services, tourism, and healthcare. Our research model classified value creation factors of the IT convergence model in twofold. The one is defined as basic value creation factor of the IT convergence, which is treated as the second-order factor that consists of two first-order factors of mobile functionality and Internet with digital contents merging functionality. The other is defined as service process limitations resolving factor which are comprised with the two first-order factors of simultaneousity and perishability. Both the second-order factors are modeled, each respectively, with the two first-order factors in formative manner. Using PLS, empirical validation is executed to analyze each value creating factor's contribution impact on the relative advantage, as well as the mediating effect of basic value creation factor on resolving service process limitations. On the basis of the insights revealed from this paper, further theory building research could be elaborated in the area of IT convergence applications for service industry.

Purpose: This qualitative study aimed to develop a substantive theory of the process of adaptation to motherhood in Central Asian-Korean immigrants to Korea. Methods: Individual, in-depth interviews were conducted from July to September 2017, with 18 women who emigrated of Korean ethnicity from Central Asia to Korea, and took care of their baby for at least a year after their first delivery in Korea. The interviews were audio-recorded and transcribed verbatim. Data from the transcriptions were analyzed through Strauss and Corbin's grounded theory method, and data analysis was conducted simultaneously with data collection. Results: As a result of categorizing the interview data through the process of open coding, 10 categories, with 31 subcategories and 102 concepts were drawn, and "growth as a Central Asian-Korean mother in an unfamiliar, historical hometown" was found to be the core category of the process of adaptation to motherhood in Central Asian-Korean immigrants to Korea. Conclusion: A characteristic of the process of adaptation to motherhood in Central Asian-Korean immigrants to Korea, drawn from this study, is that it differs according to the level of initiative to carry out interaction strategies, and the use of various supportive social resources. The findings indicate the need for Medicare eligibility adjustment for antenatal care, the extension of the visa renewal period during childbirth, the development of web- or mobile application-based educational programs in Russian language, and the establishment of integrated visiting healthcare services, community service resources, and policy support to enable these women to utilize various supportive social resources.

Purpose: This study aimed to suggest strategies for advancing local-government-based accreditation systems and surveyor training in long-term care facilities in Korea. Methods: A comprehensive review of the literature including research papers and official reports issued by governments from the United States, Australia, and Japan was conducted to explore domestic and international policies related to long-term care facility certification and accreditation systems. Results: The USA has two types of care quality assurance systems including mandatory certification (5-star rating system) by the Centers for Medicare and Medicaid Services and voluntary accreditation by the Joint Commission on Accreditation of Healthcare Organizations. Australia operates a government-based mandatory accreditation system for all long-term care facilities through the Australian Aged Care Quality Agency. Japan, particularly the Tokyo district, operates a third-party evaluation system that involves the voluntary participation of long-term care facilities. Conclusion: This study provides several strategies to enhance accreditation processes and surveyors'expertise. For instance, motivating facilities to voluntarily participate in accreditation is necessary by 1) providing sufficient and continuous consultations and feedback about how to improve care quality, 2) differentiating accreditation domains and indicators from the national health insurance certification system, and 3) actively utilizing accreditation results and providing incentives.
