Background: This study aims to compare the burden of disease in Korea with other Organization for Economic Cooperation and Development (OECD) countries using the OECD health statistics from 1985 to 2020. Methods: We analyzed potential years of life lost (YLL) per 100,000 population using the Positive value for relative comparison (PARC) index, trend test, and average annual percentage change (AAPC) with logistic regression analysis. Results: The relative disease burden was good for many diseases, but the disease burden was severe for a few diseases in Korea. Diseases with a high relative burden of disease in Korea are as follows; intentional self-harm (YLL2020 575.6, AAPCYLL 2.6%; PARC2020 -1.000, AAPCPARC -15.8%), malignant neoplasms of the liver (YLL2020 136.6, AAPCYLL -3.9%; PARC2020 -1.000, AAPCPARC 0.0%), malignant neoplasms of the stomach (YLL2020 9.0, AAPCYLL 3.2%; PARC2020 -0.556, AAPCPARC -22.9%), Parkinson's disease (YLL2020 575.6, AAPCYLL 2.6%; PARC2020 -1.000, AAPCPARC -15.8%). Conclusion: Diseases with a high burden of disease are needed to be prioritized in the planning and execution of healthcare policies that can contribute to the efficient use of healthcare resources.

BACKGROUND/OBJECTIVES: The skin is the outermost organ of the human body and plays a protective role against external environmental damages, such as sunlight and pollution, which affect anti-oxidant defenses and skin inflammation, resulting in erythema or skin reddening, immunosuppression, and epidermal DNA damage. MATERIALS/METHODS: The present study aimed to investigate the potential protective effects of red orange complex H extract (ROC) against ultraviolet (UV)-induced skin photoaging in Skh:HR-2 mice. ROC was orally administered at doses of 20, 40, and 80 mg/kg/day for 13 weeks, along with UV irradiation of the mice for 10 weeks. RESULTS: ROC improved UV-induced skin barrier parameters, including erythema, melanin production, transepidermal water loss, elasticity, and wrinkle formation. Notably, ROC inhibited the mRNA expression of pro-inflammatory cytokines (interleukin 6 and tumor necrosis factor α) and melanogenesis. In addition, ROC recovered the UV-induced decrease in the hyaluronic acid and collagen levels by enhancing genes expression. Furthermore, ROC significantly downregulated the protein and mRNA expression of matrix metalloproteinases responsible for collagen degradation. These protective effects of ROC against photoaging are associated with the suppression of UV-induced phosphorylation of c-Jun NH2-terminal kinase and activator protein 1 activation. CONCLUSIONS: Altogether, our findings suggest that the oral administration of ROC exerts potential protective activities against photoaging in UV-irradiated hairless mice.

Healthcare organizations need mutual cooperation among various medical professionals in order to carry out the performance of their duties spite of haying a strong job specialization and independence based on license. However, spite of the importance of leadership roles, there have not been enough researches dealt with leadership effect under the complex duties' relationship of a healthcare organization. This study suggested a new model by combining characteristics of leadership style, job satisfaction, and organizational commitment using Structural Equation Model (SEM). The data were self-administered questionnaires collected in 2006 from 437 employees (nurses, medical technicians, and administrative staffs) of 5 hospitals located in Seoul. The items of questionnaire were composed as a method of choosing new leadership style based on the Bass's standardized questionnaire on a Iransactionaljtransformational leadership combining the Leader Behavior Description Questionnaire-XII (LBDQ-XII) of the Ohio State University and Graen and Uhl-Bien's LMK scale through simulation techniques responding to organizational commitment. As a result, the leadership style increasing employees' self-confidence and having continuous response relationship between managers and employees improved their discretion and empowerment as well as worthwhileness and pride. However, the leadership style emphasizing reward and a sense of duty brought about a bed result that was not able to effectively respond to employees' discretion and empowerment and even weakened their worthwhileness and pride. After all, the leadership style based on vision and change had an effect on organizational commitment but the other one based on reward and a sense of duty seemed to be unsuccessful in organizational commitment. Therefore, the desirable leadership in a healthcare organization should be based on employees' self-confidence and continuous response relationship between managers and employees.

Although there are many positive sides of the current fee-for-service payment schedule, there is a strong necessity to control the rapidly increasing national healthcare expenditure. The global budget is often mentioned as one prominent alternative for solutions. In this article, both microscopic and macroscopic approaches are considered to set the hospital medical expenditure budget. In a macroscopic aspect, the SGR model, which considers the financial limit of the healthcare system, is used to set the next year target budget. In addition, the DEA model is used to measure the inefficiency and cost recognition. In this article, the national medical target expenditure is distributed to an individual hospital based on the level of efficiency. By combining the SGR and DEA, it will be possible to set a real world applicable target medical expenditure budget model.

As the elderly population increases, real-time personal health monitoring is gaining new ground with advances in wireless communications. Such an approach is particularly beneficial to elderly and physically challenged people, as well as those who live alone and are not be able to seek help in case of medical emergencies. The aim of this study is to implement a wearable band which monitors personal vital signs, such as the body temperature and heart rate, and assists with healthcare decisions using a fuzzy logic based decision support system. Since the vital sign data measured from sensors are imprecise and their normal variation with age is nonlinear and not crisp, a fuzzy system is employed to deal with this imprecise or uncertain information. The proposed wearable band is designed to continuously capture and transmit vital signs and healthcare decisions to suitable apps developed for smartphones. In this way, health alerts can be sent to the guardian or caregiver who is registered in the apps.

The purpose of this study was to examine the level of stress, healthcare accreditation related job stress, adaptation, and turnover intentions, as well as to identify influencing factors of turnover intentions for operating room nurses. This study employed a descriptive correlational design. The data were collected from 163 operating room nurses using a structural questionnaire. Stress was different by age (F=5.629, p=.004), marital status (t=-2.907, p=.004), and children (t=-2.623, p=.010). Healthcare accreditation related job stress was different by age (F=11.924, p<.001), marital status (t=-4.747, p<.001), children (t=-4.434, p<.001), work experience in the OR (F=6.000, p=.003), and work reasons in the OR (t=-2.543, p=.012). Turnover intention was different by age (F=21.472, p<.001), education level (F=4.997, p<.008), religion (t=3.235, p=.001), work experience in the OR (F=13.599, p<.001), position (t=3.222, p=.002), work reasons in the OR (t=-3.001, p=.003), and a shift pattern of duties (t=-2.797, p=.006). Turnover intention was significantly correlated with stress, healthcare accreditation related job stress, and adaptation. Factors affecting turnover intention were healthcare accreditation related job stress, adaptation, and age. These factors accounted for 36.2% of turnover intention. These results suggest that relief of stress and healthcare accreditation related job stress and interventions for improving stress management.

This study examined the awareness of the healthcare accreditation system, job stress, organizational commitment, and the turnover intention to determine the effects of these factors on the turnover intention of small and medium sized hospitals. A total of 202 nurses who worked in hospitals with less than 500 beds located in Gyeonggi-do, participated in this study. Questionnaires were given to the nurses who experienced healthcare accreditation, and data were collected between 1 December 2015 and 30 March 2016. As a result, the factors and general characteristics, influencing the turnover intention were found to be age (F=4.68, p<.001), marital condition (F=3.92, p<.001), and department of work (F=3.23, p<.008). The turnover intention was negatively correlated with the awareness of the healthcare accreditation system (r=-.46, p<.001) and nursing organizational commitment(r=-.35, p<.001), but positively correlated with the job stress (r=.21, p=.002). Regression analysis showed that the turnover intention of nurses from small and medium sized hospitals had 22.0% on the organizational commitment, department type, and job stress. Therefore, to decrease the nurses' the turnover intention, managers of small and medium sized hospitals need to draw up measures to support job involvement and policy improvement. The results also showed the difference in turnover intention according to the department type. Accordingly, there is a need for a differentiated approach according to the department of work, such as a special unit, ward, and outpatient department.

This study was conducted to investigate the effects of implementation of the healthcare accreditation system on patient safety, quality of medical care, organization culture and management performance of convalescent hospitals. Ten hospitals were selected at random from among 36 convalescent hospitals in Daegu that had obtained accreditation until September 2015. To accomplish this, hospital staff were surveyed from 15 February to 25 March, 2016 using a questionnaire with 253 objects. We investigated how the healthcare accreditation system has influenced patient safety, service quality, organization culture and performance of hospital management. The change in the treatment support system showed the highest score of 3.93 among quality change and medical service items, while that of personnel source culture showed the highest score of 3.78 points among organization culture items, and that of internal process view, study and growth view showed the highest score of 3.71 among management performance items. Multiple regression analysis revealed that factors positively changing hospital management performance were nurses, employees and managers, basic value systems, organization culture, personnel source culture, open system culture, hierarchical culture, and production oriented culture. The quality of patient safety and medical care was positively influenced by changes in the quality of convalescent hospitals after implementation of the healthcare accreditation system. However, among the four types of organizational culture, the financial perspective was relatively low compared to other perspectives.
