This study examined the effect service learning combined with self-directed study had on transferring skills from the university classroom to their practical application in local community centers. The subjects of this study were students who took service learning classes from September 1, 2019 to December 28, 2019. The research question in this paper is 'What is the relationship between service learning-based general classes and self-directed learning?'. That is, how do service learning-based general classes affect sub-elements of self-directed learning? We then tried to determine how the variables of individual learners can affect self-directed learning ability. The results showed that autonomy and problem solving were the greatest at r=.66. Openness and self-assessment (r=.60), autonomy and self-assessment (r=.55) had significant correlation. Learner autonomy had a significant correlation with facilitation and collaboration of service learning (**p<.01). According to this result of the study, it is possible for learners to deepen what they have learned at school and to practice and gain experience through community service. Further, practical problem solving and self-assessment through reflection are possible. Learners were able to inspire responsibility as members of society and increase self-esteem as democratic citizens.

BACKGROUND/OBJECTIVES: Korea is quickly becoming an aged society. Dementia is also becoming a vital public health problem in Korea. Cognitive impairment as a pre-stage of dementia shares most risk factors for dementia. The aim of the present study was to determine associations of serum levels of vitamins A, C, and E with the risk of cognitive impairment among elderly Koreans. SUBJECTS/METHODS: In this cross-sectional study, a total of 230 participants aged 60-79 years from Yangpyeong cohort were included. Cognitive function was assessed by the Korean version of the Mini-Mental State Examination for Dementia Screening. The logistic multivariable regression model was applied to determine the effect of serum vitamins A, C, and E on the risk of cognitive impairment. RESULTS: There was no significant association between the risk of cognitive impairment and serum levels of vitamin A and vitamin C. There was a significant odd ratio when the second tertile group of beta-gamma tocopherol level was compared to the first tertile group [odds ratio (OR) = 0.37, 95% confidence interval (CI) = 0.14-0.98, P for trend = 0.051]. In subgroup analyses, there were significant negative associations between beta-gamma tocopherol level and the risk of cognitive impairment in men (OR = 0.17, 95% CI = 0.03-0.87, P for trend = 0.028), non-drinkers or former drinkers (OR = 0.13, 95% CI = 0.02-0.66, P for trend = 0.025), and non-smokers or former smokers (OR = 0.27, 95% CI = 0.09-0.82, P for trend = 0.017). CONCLUSION: Serum beta-gamma tocopherol levels tended to be inversely associated with the risk of cognitive impairment. Further prospective large-scaled studies are needed to examine this association.

Purpose : This study was performed to find out the influence of the change on proprioception and coordination of the lower limb by experimentally induced paraspinal muscle fatigue, Methods : Twelve subjects(6 males, 6 females) with no history low back and lower limbs problem volunteered for this study. Subjects were pre-tested proprioception and coordination using the MR-FSS(Mornitored Rehab Functional Squat System). And then the subjects performed isometric paraspinal muscles contraction for induced muscle fatigue. Muscle fatigue was defined surface EMG(MP 150). After isometric contraction, the subjects were post-tested using the MR-FSS. Results : In comparison of coordination, deviation of concentric coordination was increased(from $0.50{\pm}0.13cm$ to $0.67{\pm}0.21$)(p<0.05) and deviation of eccentric coordination was also increased(from $0.51{\pm}0.15cm$ to $0.70{\pm}0.26cm$)(p<0.05). And deviation movement of proprioceptive test was increased(from $4.98{\pm}1.80cm$ to $5.69{\pm}1.98cm$), but there was no significant different(p>0.05). Conclusion : Fatigue of paraspinal muscles was decreased concentric and eccentric coordination of the lower limb.

Background: This study was aimed to determine the effects of deep abdominal muscle exercises (DAME) and thoracic mobility exercises (TME) on pulmonary function. Methods: This study was conducted with 22 college students who are in their 20s and have no problem carrying out activities of daily living. All subjects were randomly assigned to either the DAME group (11) or the TME group (11) to undertake the exercises for 2 weeks. To measure pulmonary function of subjects, forced vital capacity (FVC), forced exploratory volume in 1 second (FEV1) and peak expiratory flow (PEF) were measured using chest graph. Chest expansion of subjects was also measured with tape ruler. These measurements were performed on the first day before the exercise program started and on the next day after the 2-week exercise program was completed. A paired-t test was performed to compare the differences in pulmonary function before and after the exercise program, and an independent t-test was performed to compare the two groups. Results: The results of this study were as follows: 1) In comparison of pre- and post-exercise changes in the DAME and TME groups, both groups showed significant increase in chest expansion and PEF after the exercise program, compared with the baseline data (p<.05). Both groups also demonstrated improvements in FVC and FEV1 after the exercise program, compared with the baseline data. However, the differences were not statistically significant (p>.05). 2) The comparison of the DAME and TME groups revealed no significant differences in chest expansion, FVC, FEV1 and PEF (p>.05). Conclusion: It is therefore concluded that both DAME and TME were effective in improving pulmonary function.

Background: Panax ginseng C. A. Meyer is wood-cultivated ginseng (WCG) in Korea which depends on an artificial forest growth method. To produce this type of ginseng, various P. ginseng cultivars can be used. To obtain a WCG similar to wild ginseng (WG), this method is usually performed in a mountain using seeds or seedlings of cultivated ginseng (CG) and WG. Recently, the WCG industry is suffering a problem in that Panax notoginseng (Burk.) F. H. Chen or Panax quinquefolium L. are being sold as WCG Korean market; These morphological similarities have created confusion among customers. Methods and Results: WCG samples were collected from five areas in Korea. After polymerase chain reaction (PCR) amplification using the primer pair labeled with fluorescence dye (FAM, NED, PET, or VIC), fragment analysis were performed. PCR products were separated by capillary electrophoresis with an ABI 3730 DNA analyzer. From the results, WCG cultivated in Korea showed very diverse genetic background. Conclusions: In this study, we tried to develop a method to discriminate between WCG, P. notoginseng or P. quinquefolium using simple sequence repeat (SSR) markers. Furthermore, we analyzed the genetic diversity of WCG collected from five cultivation areas in Korea.
Objective: The purpose of this study was to compare with different distance across three conditions in stroke survivors with the grading of cognitive state. Design: Cross-sectional study. Methods: Twelve stroke patients who agreed to active participation were included. Participants were allotted to normal cognitive (CN) group (n=7) and cognitive impairment (CI) group (n=5) and then walked on a self-paced walkway at three conditions on the Time Up and Go (TUG) test and the 6 minute walk test (6MWT): 1) walking with your comfortable speed, 2) walking while carrying a tray with glasses, 3) walking with a verbal cognitive task. The TUG test was repeated three successful times on each condition. For the 6MWT, participants were tested one time. Results: The CI group walked slower than the CN group at the three conditions on the TUG test. However, there was no significant difference between two groups to each condition. A significant effect of dual tasking was found only in error of verbal cognitive task condition for the TUG test (p<0.05). On the 6MWT, the participants in the CI group walked short distance rather than the CN group (p<0.05). There were significant differences between two groups not only at all conditions but also at error of verbal cognitive task condition as well (p<0.05). Conclusions: To consider the results of different distances such as the TUG test and the 6MWT, we think that exercises in long distance would be more effective to patients with CI. Those would be improved patient's endurance in cognitive problem.
The purpose of this study is to explore methods to prevent and improve the problem of overdependence on smartphones by analyzing the differences in satisfaction with college life satisfaction of freshmen. For this, data on freshmen of KCYPS were extracted and used. The data were analyzed using non-hierarchical cluster(K-means) analysis, T-test, one-way ANOVA, and Scheffé tests. The results of this study are as follows. First, it has been shown that freshmen who are overdependent on smartphones experience inconvenience in their daily life, withdrawal and anxiety, and resistance. Second, there is no significant difference in the level of satisfaction with college life according to gender(t=-.015, p<.05). Third, it is shown that the level of satisfaction with college life of overdependent freshmen on smartphone is significantly lower compared to that of average and moderate dependent freshmen. Based on the results, it was suggested that university-level efforts such as emotional support and learning strategy support are needed for freshmen who are overdependent on smartphones.
The purpose of this study was to survey the cause factor and degree of stress experienced by second and third grade students of dental hygiene department in Gyeong-nam province and Ulsan Metropolitan city who were finished two weeks public health center training and four weeks dental hospital and local dental clinical training. It was to provide basic data and improve the problem of clinical training program. 1. In respect of their motives of choosing the hygiene department, 64.8% in second grade and 62.2% in third grade of those respondents cite guarantee of getting a job as main reason. In respect of the satisfaction for major field, 29.6% of second grade and 73.3% of third grade respondents were satisfied. 2. In the satisfaction for clinical training in public health center, 46.3% of second grade and 46.7% of third grade respondents were satisfied. In the satisfaction for clinical training in local dental clinic and hospital, 50.9% of second grade and 66.7% of third grade respondents were satisfied. 3. In the respect of major factor to feel stress in clinical training in public health center, the relation of school practice program and clinical training in public health center, 50.5% of respondents was felt stress because of the difference between school practice program and field condition was exist. 4. In the respect of major factor to feel stress in local dental clinic and hospital training, the relation of school practice program and clinical practice in public health center, 54.5% of respondents were felt stress. 62.1% of respondents were felt stress because of the difference between knowledge and practice. 58.1% of respondents were felt stress because of the difference between school practice program and field condition was exist. 50.5% of respondents were felt stress because of the lack of knowledge in related fields. As the above results, it is necessary to develop clinical practice program that is to increase satisfaction and provide motivation in oder to reduce the stress during clinical training.
Background: Chronic hepatitis B virus (HBV) infection related hepatocellular carcinoma (HCC) is a major health problem in the Asia-Pacific region including Thailand. Several factors have been proposed as contributing to hepatocarcinogenesis. This study was aimed to investigate the impact of CYP2C19 genotypic polymorphism in HCC related to chronic HBV infection in Thailand. Materials and Methods: A cross-sectional study was performed between April 2014 and January 2015. Chronic HBV patients with HCC (n=50) and without HCC (n=50) were included. Clinical information and blood samples of all patients were collected. The CYP2C19 genotype was determined by polymerase chain reaction-restriction fragment length polymorphism method, and was classified as rapid metabolizer (RM), intermediate metabolizer (IM) or poor metabolizer (PM). Results: The CYP2C19 genotype frequencies of RM, IM and PM in HBV patients were found to be 19/50 (38%), 25/50 (50%) and 6/50 (12%), respectively. The CYP2C19 genotype frequencies of RM, IM and PM in HBV with HCC patients were 21/50 (42%), 25/50 (50%) and 4/50 (8%), respectively. The distribution of CYP2C19 genotype was not different between patients with and without HCC. Interestingly, among HBV with HCC patients, the RM genotype of CYP2C19 tended to increase risk of aggressive manifestation (OR=2.89, 95%CI=0.76-11.25, P-value=0.07), compared with non RM genotype carriers. Conclusions: CYP2C19 genotype IM was the most common genotype in Thai patients with chronic HBV infection. In addition, genotype RM could be an associated factor for aggressive presentation in HCC related to chronic HBV infection.

Background: There is little data on the 3 year prognosis and quality of life of patients on long-term (>72 hour) mechanical ventilation in a medical intensive care unit (MICU). Methods: Patients with long-term mechanical ventilation from May 2003 through July 2003 in MICU of Asan Medical Center, Seoul were enrolled in this studay. The survival rates were observed prospectively at 1, 3, 6, 12, 24, 36 months, and the quality of life of survivor was measured at 12 months by using Short Form 36 (SF-36). Results: The survival rate at 1, 3, 6, 12, 24 and 36 months was 54.8% (40/73), 39.7% (29/73), 30.1% (22/73), 20.5% (15/73), 18.3% (13/71) and 16.9% (12/71), respectively. There was a similar survival rate regardless of the diseases that required mechanical ventilation. A neoplasm or chronic liver disease had a worse survival rate than chronic lung or kidney disease (p<0.05). Each SF-36 domain except for the Role-emotional was inferior to the general population. Conclusions: The survival rate of patients with mechanical ventilation more than 72 hours is decreases continuously until 12 months but is relatively constant from 12 to 36 months. In these patients quality of life is also decrased.
