Mulberry (Morus sp.) of the family Moraceae is very economically important in Asian countries including Korea, because its leaf and fruit have been commercially used in sericulture and horticultural industries. Therefore it is necessary to develop the optimal production system for rapid and cost-effective propagation of mulberry. Our studies focused on establishing an acclimatization method for the successful plantlet production of new cultivar 'Cheongsu' which was transferred ex vitro after in vitro culture. In particular, effect of abscisic acid (ABA) addition into the last subculture medium on plantlet response to subsequent ex vitro transfer and its growth was investigated. During acclimatization, stomatal conductance and transpiration rate of ABA-pretreated plantlets were significantly lower than those of non-treated plantlets. Net photosynthetic rate of ABA-pretreated plantlets decreased after ex vitro transfer but increased after 14 days, and it was mostly higher than that of non-treated plantlets. Moreover, relative water content as well as chlorophyll contents and its ratio were also higher in ABA-pretreated plantlets. On the other hand, proline was considerably higher than in control plantlets. After 1 month of ex vitro transfer, survival rate of ABA-pretreated plantlets was 85.6%, which increased by 29.1% in comparison with control (56.5%). More vigorous growth was also observed in ABA-pretreated plantlets. From these results, it was found that application of ABA to the last subculture medium could improve acclimatization and promote survival of mulberry plantlets after ex vitro transfer, inducing water stress tolerance and alleviating abiotic stresses.

This study was carried out to elucidate the influence of gibberellin soak and seed dressing with Toros wp. on the dehiscence of Eleutherococcus senticossus seeds. $GA_3$ treatment was effective on promoting after-ripening seed of Eleutherococcus senticossus whose concentration was higher until $500\;mg{\cdot}L^{-1}$, after-ripening period became shorter. But rotting percentage increased gradually up above $500\; mg{\cdot}L^{-1}\;GA_3$After all, $300\;mg{\cdot}L^{-1}\;GA_3$ was the most effective treatment for promoting after-ripening seed. Dressing treatment with Toros wp. on seeds reduced the dehiscent rate of E. senticosius. by suppressing activity of fungi living on the endocarp surface of seed.

The increasing elderly population has created an urgent need for well-managed convalescent hospitals, which should provide appropriate clinical nutrition services. The new accreditation policy requiring participation of all convalescent hospitals since 2013 may promote improvement of clinical nutrition services. This study examined whether or not the accreditation policy has increased practice level and dietitians' perception of the importance of clinical nutrition management. Of the 177 convalescent hospitals accredited by January 30, 2014, dietitians from 73 hospitals (41.2%) completed the survey questionnaire. The pre-tested questionnaire surveyed general characteristics of the hospital and dietitians, current status of clinical nutrition management, and changes in the perception and practice levels of various aspects of food and clinical nutrition management. In average, dietitians with more than 5 years of work experience (68.1%) provided food and clinical nutrition services (71.2%). After accreditation, dietitians' perception of the importance and practice level of clinical nutrition service increased (P<0.001). Level of perception, however, was significantly (P<0.001) higher than practice level before and after accreditation. During perception and practice level of initial nutrition assessment, a compulsory accreditation item, notably and significantly (P<0.001) improved after accreditation. The significant difference between perception and practice level disappeared after accreditation. In conclusion, the accreditation process had positive effects on clinical nutrition management in terms of dietitians' perception and practice levels. Making more accreditation items compulsory and providing motivation and professional education to dietitians in convalescent hospitals could lead to additional improvements.

Objectives: The purpose of this study is to investigate changes in public health-related perceptions of residents of Gangwon province after the outbreak of Coronavirus disease-19(COVID-19) of the public. Methods: We performed paired T-test analysis to measure the change in public health-related perceptions before and after COVID-19. We also utilized generalized estimating equations to identify demographic factors correlated with public health-related perceptions. Results: The public perceived public health as 'All citizens can use medical care and protect/promote health.' The concept was the most popular, from 94.3% in 2019 to 95.5% in 2020. In addition, after COVID-19, residents of Gangwon province's satisfaction with medical services increased, but the overall level was not high. Among the eight essential healthcare needs after COVID-19, cardiovascular disease and injury services have emerged as preferred services. However, by sociodemographic factors, distinctive responses were detected. Conclusions: Through COVID-19, Gangwon residents' awareness of the public's health rights has increased. Those living in vulnerable areas or with unmet medical care, supported strengthening public health care. In addition, although medical satisfaction has increased, it is not satisfied, so listening to the voices of the population group with low satisfaction is essential. Lastly, since the necessity of essential health care may change due to specific events, the local government needs to plan health projects reflecting the needs of residents. Therefore, when designing the public health care strategy in Gangwon province, the local government should consider not only political factors but also environmental factors, demographic and conceptual factors.

Seven diagnosis-related groups (DRGs) prospective payment system is going to expand to all hospitals including university hospitals this year. However there are few studies on the change of practice pattern under prospective payment system in the university hospital setting. So This study was intended to predict the practice pattern change after the introduction of 7 DRGs prospective payment system in a university hospital setting. To predict the change of practice pattern, this study used simulation technique. Five hundred and nineteen patients classified as 5 DRGs in a university hospital were selected for simulation. The change of practice pattern were predicted based on clinicians' opinion. We also predicted payment change by service items. Major findings of this study are as follows. First, the total medical payment was reduced by 14.4%. The drug payment change (8.8%) took most of total payment reduction. The followings are the change of treatment material cost (3.2%), the change of laboratory tests cost (1.8%), the change of room charge (0.5%), and other payment change (0.1%), respectively. Second, most of the reduction in total medical payment resulted from the decreased amount of medical services themselves. The transfer of medical services to outpatient setting took up only 4.9% of the total payment reduction. The change of unit price or composition took up 5.5% of the total payment reduction. In this study we found that it is possible to reduce the inpatient services through practice pattern change in university hospital setting. However, it needs to be careful to adjust DRG payment after the reduction of provided services, because most of reduction was not due to service transfer but to service volume reduction. It is desirable to utilize the saving from practice pattern change as incentive to improve quality of care.

To test if the developed ubiquitous health care devices working well and vital information could be collected and monitored systematically through internet and to test if the devices and services could be used further. Kyungwon University, KT Co., Gil Medical Center, LIG Nex1 Co., and Sujeong Health Center conducted an ubiquitous health care demonstration project in Sujeong-Gu, Sungnam, Korea from Mar. 5 to May 16. We developed and applied several medical devices to monitor health of the elderly in their houses through internet. The devices were sphygmomanometer, glucometer, body fat scale, Health Pad, and activity sensor. We distributed the devices to 20 recipients of home care and 7 diabetes patients. After received the devices and were explained how to use them, they used the devices in their houses. The vital signs of the residents were monitored through internet. A nurse monitored and consulted their vital signs in the monitoring center in Kyungwon University during the demonstration period. The consultant called them and consulted on their blood pressure, blood sugar level, and body fat after a few seconds they used the devices as well as provision of recommended contents such as diets and activities through Health Pad. To investigate cognition and satisfaction of the participants for the devices, we surveyed the participants at the end of the demonstration period. For the change in blood pressure, blood sugar level, and activities, we conducted statistical test. After the demonstration period. cognition and satisfaction for the devices and change in blood pressure, blood sugar level, and activities were evaluated. Most of the participants were acknowledged how to use the device and satisfied with the use of the devices. The internet monitoring and services are considered to be promising because most of the participants were satisfied especially because somebody was monitoring their health status. However some weaknesses such as short battery life of the activity sensor, lack of connection of consultations with hospitals, and low understanding on usage of some of the devices need to be complemented.

Purpose: This study utilized a strong quasi-experimental design to test the hypothesis that the implementation of a policy to expand dental care services resulted in an increase in the usage of dental outpatient services. Methods: A total of 45,650,000 subjects with diagnoses of gingivitis or advanced periodontitis who received dental scaling were selected and examined, utilizing National Health Insurance claims data from July 2010 through November 2015. We performed a segmented regression analysis of the interrupted time-series to analyze the time-series trend in dental costs before and after the policy implementation, and assessed immediate changes in dental costs. Results: After the policy change was implemented, a statistically significant 18% increase occurred in the observed total dental cost per patient, after adjustment for age, sex, and residence area. In addition, the dental costs of outpatient gingivitis treatment increased immediately by almost 47%, compared with a 15% increase in treatment costs for advanced periodontitis outpatients. This policy effect appears to be sustainable. Conclusions: The introduction of the new policy positively impacted the immediate and long-term outpatient utilization of dental scaling treatment in South Korea. While the policy was intended to entice patients to prevent periodontal disease, thus benefiting the insurance system, our results showed that the policy also increased treatment accessibility for potential periodontal disease patients and may improve long-term periodontal health in the South Korean population.

The aim of this study was to examine the current turnover status of hospital pharmacists and to analyze the factors which affected the turnover of them after the separation of prescribing and dispensing practice. We surveyed 19 managers of hospital pharmacies and 154 hospital pharmacists. Results are as follows. Pharmacist manpower of hospital pharmacies was only $63.99\%$ in tertiary hospitals and $76.78\%$ in general hospitals respectively of the number of pharmacists before the separation of prescription and dispensing practice. The ratio of those who left hospital pharmacies during the period of January 2000 and October 2001 was $80.23\%$ for tertiary hospitals, and $100.84\%$ for general hospitals. Decrease in the number of pharmacists brought the increase of work load and night duty. Major factors which affected the turnover of hospital pharmacists were found as following: income gap between hospital pharmacists and community pharmacists, increasing workload especially at night and on holidays, infrequent chance for the promotion, and low chance to provide clinical pharmacy services after the separation of prescribing and dispensing practice. Adequate manpower is the basic factor for providing hospital pharmacy services and improving clinical pharmacy services. The study suggested that proper number of hospital pharmacists is to be ensured through strengthening the legal requirement for the hospital pharmacists and improving health insurance reimbursement rate for the pharmaceutical services at hospital.
