This study explores the effects of exports on the innovation of Korean firms listed on two Korean stock markets, the Korean Stock Exchange and the Korean Securities Dealers Quotations, between 1999 and 2016. By matching exporting firms to non-exporting ones with propensity score matching, this study accounts for a problem from sample selection bias that may arise from differences in firm-characteristics between the two groups. From the study results, first, both export participation and export volume significantly increase subsequent innovation performance, as measured by the number of patent applications. This result seems to support the "learning by exporting" hypothesis for Korean listed firms. Second, both export participation and export volume narrow innovation scope, proxied as the number of unique International Patent Classification (IPC) codes of the patent applied, the degree to which patents are concentrated in a particular class, and the degree of proximity in the patents. The findings of innovation scope suggest a possible explanation that the learning effect appears in familiar technology fields that firms have previously held, rather than in unfamiliar ones. Third, these results are robust using alternative proxies in the innovation scope, Tobit regressions to consider the non-trivial portion of sample firms with patent applications equal to zeros, and generalized method of moments (GMM) to control for the persistence of innovation measures hearing over years. Finally, the two main results are more pronounced in large firms than in small and medium-sized ones. As for Chaebol firms, however, these results do not appear.

This study analyzed per capita consumption expenditure by the consumption quintile of Middle and Older Elderly Households and the variables that affected it. Sample of 2,983 households was collected from the 6th KLoSA in 2016. First, when comparing the HH's living expenses by the number of family members, two persons to a person ratio, more than six persons to a person ratio were 2.007 and 4.148, respectively. The ratio increased as the number of family member increased; however, the rate of ratio increase decreased. Second, the per capita living expenses for the first and fifth quintile were 5.11 million won and 16.93 million won at the per capita living expenses that applied the OECD's equivalence scale to the HH's living expenses. The per capita living expenses for the fifth quintile was 3.31 times higher than in the first quintile. Third, among the variables influencing per capita living expenses by the consumption quintile, the marital status was the significant for all consumption quintiles; however, HH's income, HH's total asset, HH's financial asset, pension, subjective perception of the economy class, home ownership, residence (metropolitan or small city), education (elementary school), participation groups were significant in some quintiles among all quintiles. Fourth, of the significant variables influencing per capita living expenses, the most influential variables were first quintile followed by second quintile, third quintile, fourth quintile, marital status, HH's income, home ownership, HH's total asset, participation groups, residence (metropolitan), subjective perception of the economy class, in order.

This study investigated associations between exercise habit and bone mineral density (BMD) and bone mineral content (BMC) in postmenopausal women. The BMD and BMC of the spinal skeleton was measured by dual energy x-ray absorptiometry. Exercise and energy expenditure of physical activity were estimated by questionnaire. For exercise activities, subjects were asked to identify all exercises they have participated in. The subjects were further asked to estimate the number of years of participation, the number of weeks per year, the number of times per week, and the number of hours per time. Subjects were then categorized into exercise (more than 3 times/wk, more than 30min per session exercise (n = 47) and nonexercise group (n = 72). Results indicated that there were no significant differences in BMD and BMC when comparisons were made between subjects in exercise habit, a general exercise group and a nonexercise control group. However, when exercise subjects were divided into weight-bearing and nonweight-bearing groups, significant differences were found. These results suggest that weight-bearing exercise positively influences bone mineral density and bone mineral content in postmenopausal women. Sedentary women should be encouraged to adopt a weight-bearing exercise to maintain the health of their skeletons. Exercise interventions are practical and feasible for healthy women and should be encouraged at the earliest possible age. Our findings lend support to recommendations for physical activity and weight-bearing exercise as a means of osteoporosis prevention.

Purpose: Since 2010, many universities in Korea have been implementing Green Leader Training Programs which are usually run by students themselves. In the last five years of 2015, the Green Leader Training Program under the sponsorship of Korean Association for Green Campus Initiative has promoted the practice of a green campus and many relative projects have been carried out in various fields. Method: We utilized the green campus component index established by the Presidential Committee on Green Growth in Korea and have analyzed 480 activities during the years of 2010~2015. Result: We found that many activities were classified into the environmental field(264, 55.0%). This was followed by university members' participation(130, 27.1%), community engagement(68, 14.2%), and university management(18, 3.7%). These results showed that the green campus initiatives were focused on the environmental field. The number of universities participating from 2010 to 2015 were 20 in the metropolitan area and 15 in the non-metropolitan are. In the metropolitan area, 81.7% of green leader activities were conducted at universities in Seoul, and those in non-capital areas were active in the Middle region(51.3%) and Yeongnam region(48.7%). On the other hand, there was no activity in the Honam region, and it shows that there was a noticeable differential by regional groups.

The increased number of elderly in Korea presents great challenges for community nutrition programs. Strategies to enhance elderly nutrition are needed, as well as dietary advice that are reality-based and tailored to the need of the elderly. The purpose of this study was to evaluate the overall effectiveness of an elderly nutrition improvement program(ENIP), by assessing changes in nutrition knowledge, attitudes, and behavior after program completion. ENIP was conducted in Suwon for 4 months in 1998 at 5 centers for the elderly. The program provided individual nutrition counseling and brief biweekly group education sessions. To stimulate participation and motivation, the elderly in two centers were served free milk packs(200ml) three time a week during the program(milk＋education group), and the elderly in 3 other centers were served yoghurt on the program day(education group). Altogether, 102 subjects finished the program(milk＋education group 67 ; education group 35). Data about nutrition knowledge, dietary attitudes, diet records(24 hour recall) and dietary habit was collected before(baseline) and after the program(follow-up). The Drop-out rate for the milk＋education group(2.9%) was significantly lower than that for the education group(30.0%)(p<.001). The Nutrition Knowledge fo females milk＋education group increased significantly after the program, but no significant differences were observed in other groups. Over 60% of all the elderly showed positive responses to the healthy eating attitudes. Energy, protein, vitamin A, riboflavin, Calcium and Potassium intakes improved in the male milk＋education group. The Vitamin C intake improved in the male education group. Energy and vitamin A intakes improved in the female milk＋education group and energy, vitamin A, thiamin, riboflavin, niacin, Ca nad P in the female education group. A stepwise multiple regression analysis was performed to examine the effects of food intake changes on overall nutrient quality. For all elderly, the fish intake explained 12.6% of the variance, followed by candy intake and vegetable intake(model $R^2$=19.6%). Dietary habits such as meal time regularity and salty food reduction were markedly improved in both groups. Sixty-one percent of the milk＋education subjects stated their participation was voluntary and active, while 51% of education subjects did. Sixty four percent of the subjects stated their interest on diet increased remarkably through program participation. Considering the results, it is conjectured that ENIP had a great impact on nutrient intake, dietary attitudes and habits. Milk supplement showed no direct effects on elderly nutrition improvement, but it encouraged the program by reducing drop-out rates and inducing voluntary participation. Therefore milk supplement could enhance the community nutrition education program. Moreover it is strongly suggested that the ENIP be expanded to other communities.

The purpose of this study is to examine the effects of the rural community planning focusing on the stepwise empowerment system in Jinan-gun, Jeollabuk-do province. This paper also tries to examine how this system affect the awareness for community planning and empowerment of the residents. The satisfaction of the people who join this program were also investigated. The subjects of the research were divided into two groups. Group A consisted of the people who join the system from the first stage, and group B consisted of the people who joined the fourth stage directly. The differences of the recognition, capability changes and satisfaction between two groups were compared and analyzed by questionnaires. The results of this research can be summarized as follows. The first, group A recognized the community planning system in Jinan-gun more positively than group B. They thought that it's very useful and beneficial for their community and this system should be continued further. The second, group A considered that they achieved bigger advancement in community design capabilities in terms of personal, relational and social aspects than group B. In addition, group A also showed higher satisfaction for rural community planning than group B. Based on the results, alternatives for rural community planning were drawn as follows. The first, considering that group A showed more positive responses, starting from the first stage is more stable way to succeed in rural community planning. Which means the critical condition of community design is not the community business but the improving the public awareness and community mind. The second, it's considered that the number of participation is proportional to the advancement of capability in community project, so improving residents' opportunity to participation in community design might be effective. The third, community leader is another critical condition. It is needed to pay more attention to the education for the rural community leader with good experience and capability of community affairs.

Health Information Exchange (HIE) is expected to improve the quality and efficiency of care by allowing providers online access to healthcare information generated by other providers at the point of care. However, the adoption of the technology in Korea has been slow since its pilot program in 2007~2010 at Seoul National University Bundang Hospital. The objective of this study was to survey stakeholders on the incentive program for the facilitation of HIE adoption. We surveyed 39 experts representing 6 categories of stakeholders-provider, insurer, government, information service firms, customers, and medical informatics experts for the interviews. Interview questions included program objectives, program participation requirements, incentive payment method, and administrative burden for program participation. Experts indicated that the quality of care was the most important value the program should aim to achieve through the HIE adoption. They suggested that the requirements and administrative burden for participation should be kept at minimum to recruit a large number of providers to the program, which is an indicator of program success. Experts were divided on the payment method whether the incentive should be paid as a part of the fee payment scheme operated by the National Health Insurance (NHI) or should be a payment made independent of the NHI. The source of the divide was conflict of interest among stakeholders as to who pays for the program, and the insurer and consumer groups were against the NHI taking the financial burden. It appeared to be the most significant factor for the successful program launching to resolve the gap in perceptions about benefits of the technology among stakeholders and to win the willingness to pay for the program.

Background: Pregabalin is an anticonvulsant and analgesic agent that interacts selectively with the voltage-sensitive-$Ca^{2+}$-channel alpha-2-delta subunit. The aim of this study was to evaluate whether the analgesic action of intrathecal (IT) pregabalin is associated with KATP channels in the rat formalin test. Methods: IT PE-10 catheters were implanted in male Sprague-Dawley rats (250.300 g) under inhalation anesthesia using enflurane. Nociceptive behavior was defined as the number of hind paw flinches during 60 min after formalin injection. Ten min before formalin injection, IT drug treatments were divided into 3 groups: normal saline (NS) $20\;{\mu}l$ (CON group); pregabalin 0.3, 1, 3 and $10\;{\mu}g$ in NS $10\;{\mu}l$ (PGB group); glibenclamide $100\;{\mu}g$ in DMSO $5\;{\mu}l$ with pregabalin 0.3, 1, 3 and $10\;{\mu}g$ in NS $5\;{\mu}l$ (GBC group). All the drugs were flushed with NS $10\;{\mu}l$. Immunohistochemistry for the $K_{ATP}$ channel was done with a different set of rats divided into naive, NS and PGB groups. Results: IT pregabalin dose-dependently decreased the flinching number only in phase 2 of formalin test. The log dose response curve of the GBC group shifted to the right with respect to that of the PGB group. Immunohistochemistry for the $K_{ATP}$ channel expression on the spinal cord dorsal horn showed no difference among the groups 1 hr after the formalin test. Conclusions: The antinociceptive effect of pregabalin in the rat formalin test was associated with the activation of the $K_{ATP}$ channel. However, pregabalin did not induce $K_{ATP}$ channel expression in the spinal cord dorsal horn.

Background: Pharmacists communicate with a variety of healthcare experts to prevent medication errors. Situation-Background-Assessment-Recommendation (SBAR) is a tool used for concise and accurate communication. In 2018, we developed the pharmacy-SBAR (P-SBAR) to deliver pharmacists intervention more quickly and effectively through quality improvement activities. Objectives: This study evaluates the efficacy of P-SBAR on pharmacists' intervention activities before and after the implementation of P-SBAR applications. We assessed the impact of P-SBAR on reducing the burden of intervention work, promoting pharmacists' participation, and enhancing the acceptance rate. Methods: This is a retrospective study of the two groups before and after P-SBAR implementation. All pharmacists' intervention records during two periods (2016-2017 and 2019-2020) were extracted from the data warehouse system at Kyunghee University Hospital at Gangdong, Seoul. The outcome was the number of inpatients and pharmacists who participated in the prescription monitoring activity, the number of interventions, and the physicians' acceptance rate. Results: Although the total number of inpatients decreased (364,753 vs. 348,229), the number of pharmacists who participated in intervention activity increased (monthly mean: 15.8 vs. 18.0, p=0.001). The total number of interventions (2,767 vs. 4,389), the frequency of full acceptance (2,018 vs. 3,710), and the monthly acceptance rate increased significantly (73.8% vs. 83.8%, p<0.001). Conclusion: P-SBAR improved accessibility and convenience by digitalizing the intervention activities performed in an offline environment. Improvement in work burden and acceptance rate using P-SBAR is expected to contribute toward reducing medication errors.
