The purpose of this study was to investigate the effects of the satisfaction of college students majoring in healthcare-related fields with their major and with their clinical practice on their career decision-making level and to investigate the mediating effect of their satisfaction with clinical practice on the relationship between their satisfaction with their major and their career decision-making level. The subjects were 180 college students who had completed clinical practice as part of their healthcare-related majors at C University in A-gun, B-do Province. Their completed questionnaires were collected between March 2 and March 5, 2020; 165 questionnaires were used for the data analysis. Questionnaires with missing or insincere responses were excluded. According to the results of this study, the students showed a mean of 3.99 points in their satisfaction with their major, 3.33 points in their career decision-making level, and 3.71 points in their satisfaction with clinical practice. Statistically significant positive correlations were found between the students' satisfaction with their major, their career decision-making level, and their satisfaction with clinical practice. In addition, their satisfaction with clinical practice produced a partial mediating effect on the relationship between their satisfaction with their major and their career decision-making level, and those with a higher level of satisfaction with their major and with their clinical practice also presented higher career decision-making levels. Therefore, the present study suggests that healthcare-related students' satisfaction with their major and with clinical practice should be enhanced to increase their career decision-making levels.

The purpose of the review article was to summarize and discuss the available information concerning the effect of bleaching on human teeth and reduced treatment on negative influence. Tooth bleaching effect was differ from extent of concentration and application period of a tooth bleaching agent, certainly full knowledge prior treatment about adverse effect possible appearance and follow clinical treatment for the least reduce. It remains unclear in how far those observation may result in significant adverse effect under clinical conditions. Nevertheless, further investigation are necessary to elucidate these aspect more precisely. The findings of the study were as follows : 1. It is recommended to delay placement of restorations after termination of bleaching therapy for at least 1-3 weeks. 2. Reduced negative influence that is clinical feasibility of catalase in protecting bleached surface against Oxygen radical. 3. The residual peroxide in tooth after bleaching seems to be removed by gradual diffusion and it may be possible to eliminate the adverse effect on tooth by using water displacement solution, ethylalcohol and aceton including it for effective removal of free radical oxygen.

Raphiolepis indica (R. indica) is one of evergreen shrubs belonging to the Rosaceae and is grown wildly in Jeju. This study was performed to evaluate the hepatoprotective effect of different fractions (n-hexane, dichloromethane, ethyl acetate, butanol, water) from R. indica. Anti-oxidative effects were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and total phenol contents. Hepatoprotective effect was identified by 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay in Huh7 cells. Among various fractions, ethyl acetate and butanol fractions showed the lowest DPPH remained rate reaching approximately 78.7 and 65.5% at $400{\mu}g/mL$. Ethyl acetate and butanol fractions showed the total phenolic content at 164.5 and 137.3 mg GAE/g extract. The ethyl acetate and butanol fractions were resistant against oxidative stress in MTT assay and showed higher hepatoprotective effect than other fractions. Therefore, these results suggest that the ethyl acetate and butanol fractions of R. indica might have therapeutic value in liver damage.

Purpose: The purpose of this study was to systematically review and identify factors relevant to the positive psychological capital of clinical nurses. Methods: These was no limit on year of publication. Articles related to Korean clinical nurses were retrieved from computerized database using a manual search. A systematic review was conducted based on the PRISMA flow. The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. Funnel plots, fail-safe numbers, and Egger regression tests were used to evaluate publication bias in meta-analysis studies. The correlational effect size of 25 studies was analyzed through meta-analysis using Comprehensive Meta-Analysis software 3.0 (CMA). Results: The review included 25 studies. In the systematic review, 14 demographic factors and 46 organizational factors were found to be influential. Eleven factors (6 demographic factors and 5 organizational factors) were appropriate for meta-analysis. The overall effect size was .26. The demographic total correlation effect size of related factors was .20 and the total effect size of organization was .46. Organizational commitment (ESr=.38) and job satisfaction (ESr=.54) were statistically positively related variables. Negative variables were burnout (ESr=-.61), turnover intention (ESr=-.41) and workplace bullying (ESr=-.33). The total effect size of the organizational factors was larger than the demographic total effect size. There was no publication bias except for demographic variables. Conclusion: Organizational factors and adjustable variables have a significant impact on positive psychological capital. The results of this study support the need for development of interventions focusing on organizational factors.

Type 2 diabetes mellitus relavant to insulin resistance is a chronic and hard to control. In order to develop an antidiabetic agent from natural products, anti-hyperglycemic effect of herbal formula containing Mori Follium, Euonymi Lignum Suberalatum and Ginseng Radix(MEG) was investigated in db/db mice. Treatment group was administered orally with MEG formula at a dose of 300 mg/kg for 5 weeks, and blood glucose, insulin and lipid levels were determined. MEG treatment group showed a marked decrease in fasting blood glucose level and insulin resistance index(IRI) compared to those in diabetic control. Improvement of insulin resistance(60.6%) was indicative of reducing lipid levels in plasma and triglyceride contents in muscle and adipose tissue. In addition, expressions of an insulin responsive gene, glucose transporter 4(Glut4), in muscle and adipose tissue were upregulated in MEG treatment group. Compared islet morphology between groups, MEG formula prevented the ${\beta}$-cell destruction caused by high blood glucose. Taken together, MEG formula can act as an anti-hyperglycemic agent with insulin sensitizing effect, and thus deserves a clinical trial in the future.

Objective: This study was conducted to investigate the lipid-lowering effect and safety of Daeshiho-tang in patients with uncontrolled lipid levels by statins. Methods: We investigated patients who had an abnormal lipid profile even when taking statins and who were administered Daeshiho-tang at Kyung-Hee University Korean Medical Hospital for at least one day between January 2008 and December 2018. Their basal characteristics and examinations were reviewed retrospectively with respect to lipid profile, AST, ALT, GGT, BUN, and creatinine. The lipid profile was composed of total cholesterol, triglyceride, LDL-cholesterol, and HDL-cholesterol. Subgroup analysis was performed on each component of dyslipidemia. Results: Among 20 participants, there were 10 males and 10 females. The mean BMI was 23.52. Eighty five percent of the participants were diagnosed as having cerebral infarction. After the administration of Daeshiho-tang, total cholesterol and LDL cholesterol were significantly reduced, to 41.3 mg/dl and 33.95 mg/dl, respectively. In subgroup analyses, total cholesterol and LDL cholesterol were significantly decreased, to 63 mg/dl and 54.6 mg/dl, respectively. Liver and kidney function showed no significant difference after taking Daeshiho-tang. Conclusions: Daeshiho-tang as a decoction or powder had significant lipid-lowering effects on total cholesterol and LDL cholesterol in patients with dyslipidemia. The lipid-lowering effect on total and LDL cholesterol increased in patients with hypercholesterolemia and hyper-LDL-cholesterolemia, respectively. Based on the minimal changes in the liver and kidney function test, Daeshiho-tang would be safe enough to be used in clinics.

Objective: This study aimed to determine the safety and clinical effect of artificial shrinkage (AS) in terms of assisted hatching of fresh blastocysts. Also, we evaluated the correlation between patient age and the effect of AS on clinical outcome. Methods: Two AS methods, using a 29-gauge needle and laser pulse, were compared. Seventy-three blastocysts were shrunk using a 29-gauge needle and the same number of other blastocysts were shrunk by a laser pulse. We evaluated the shrunken blastocysts hourly and considered them viable if they re-expanded >70%. Blastocyst transfer cycles (n=134) were divided into two groups: a control group consisted of the cycles whose intact embryos were transferred (n=100), while the AS group consisted of the cycles whose embryos were replaced following AS (n=34). The implantation and pregnancy rates of the control group and AS group were compared ($p$ <0.05). Results: The re-expansion rates of the 29-gauge needle and laser pulse AS groups were similar (56 [76.7%] vs. 62 [84.9%], respectively). All of the remaining shrunken blastocysts were re-expanded within 2 hours. There was no degeneration of shrunken blastocysts. The total and clinical pregnancy rate of the AS group (23 [67.6%]; 20 [58.8%], respectively) was significantly higher than that of the control group (47 [47.0%]; 39 [39.0%], respectively). In the older patient group, there was no difference in the clinical outcomes between the AS and control groups. Conclusion: These results suggest that AS of blastocoele cavity, followed by the transfer, would be a useful approach to improve the clinical outcome in cycles in which fresh blastocyst stage embryos are transferred.
