Purpose: This study aimed to investigate the mediating effects of health promotion behavior (HPB) in the relationship between anxiety and quality of life (QoL) in young adults living in the post-pandemic era. Methods: A cross-sectional descriptive online survey design was utilized. Data on anxiety, QoL, HPB, and demographic characteristics were collected from 213 adults aged 19-35 years in Korea via an online survey in January 2024. The collected data were analyzed using SPSS 27.0 and PROCESS MACRO 4.2 software. Results: Strong correlations were observed among anxiety, QoL, and post-pandemic HPB (PP-HPB) in young adults, and anxiety and PP-HPB were identified as significant predictors of QoL. The total effect of anxiety on QoL was significant (B = -1.40, bootstrapped SE = 0.10), with both the direct effect (B = -0.70, bootstrapped SE = 0.09) and the indirect effect (B = -0.70, bootstrapped SE = 0.11) being significant. This suggests that PP-HPB partially mediated the relationship between anxiety and QoL. Conclusion: This study highlights the importance of strengthening HPB with consideration of life changes since the coronavirus disease 2019 pandemic to improve QoL among young adults with anxiety.

Purpose : This study aimed to evaluate the effects of a cognitive enhancement brain yoga program on short-term memory and serum brain-derived neurotrophic factor (BDNF) levels according to the cognitive state in men aged 20-29 years. Methods : Thirty healthy volunteers aged 20-29 years were divided into four groups: brain yoga group, yoga group, combined exercise group, and control group. Seven people were assigned randomly per group. A single-session intervention was conducted over 50 min and consisted of three parts: warm-up, main exercise (brain yoga, yoga, combined exercise, or non-exercise), and cool-down. Serum BDNF levels were measured using enzyme-linked immunosorbent assay, and short-term memory was evaluated using the forward number span test before and after the intervention. Results : BDNF levels significantly increased within the brain yoga group after the intervention (from 28874.37±5185.57 to 34074.80±7321.12, p=.003), whereas there were no significant differences pre-and post-intervention in the other groups. The inter-group comparison showed a significant interaction between the brain yoga group and the combined exercise group (p=.036) but no significant interaction between any of the other groups. Forward number span scores were significantly increased in the brain yoga group (from 9.43±9.83 to 23±7.92, p=.012) and theyoga group after the intervention (from 13.43±9.41 to 24.14±8.45, p=.011), whereas there were no significant changes after the intervention in any other groups. Conclusion : Our findings showed that a single-session, 50-minute brain yoga exercise improved short-term memory and increased serum BDNF levels in healthy men aged 20-29 years and that yoga improved only short-term memory in healthy men of this age group.

The purpose of this study was to assess the effect of nutrition education by the difference of BMI(Body Mass Index) group for adults at rural area. Eighty four adults (mean age : 55.9$\pm$11.8) participated in nutrition education program. Data collection includes measured physical status and serum collections for health status. The impact of nutrition KAP (knowledge attitude and practice) and retention was examined among participants who were assessed at program entry, 3 times of education and 1 month of follow-up. The results were as follows: The participants were composed 14 persons of under 20kg/$m^2$ of BMI, 40 persons of 20-25 and 27 persons over 25 of BMI , female 60 persons but male 23 only. Serum albumin and calcium content of female(3.5$\pm$1.2g/㎗, 7.5$\pm$3.9mg/㎗) were significantly lower than males(4.7$\pm$0.9g/㎗, 11.2$\pm$4.6mg/㎗) but there was not significantly different with BMI groups. Serum TG and cholesterol contents of over 25kg/$m^2$ of BMI group(157$\pm$87mg/㎗, 249$\pm$16mg/㎗) were higher than other groups, but significantly different in cholesterol contents only. Via the 10 questions of nutrition attitude, the participants improved significantly between pre and post education(the score of pre, post and after 1 month, 6.5$\pm$1.8, 7.2$\pm$1.5, 7.2$\pm$1.9), and were also attributed to better personal feeling health by modified CMI test, but dietary food habit was not significantly improved. As the differences of BMI groups were compared, 20-25kg/$m^2$ group had better the effect of nutrition education score than other groups, and female had better nutrition attitude and practice score than male.

The purpose of this study was to evaluate effects of sacroiliac joint mobilization and lumbopelvic stabilizing exercises on the equilibrium ability. The subjects were consisted of ninety healthy adult two decade(43 females. 47 males; mean aged 22.1) from 20 to 29. All subjects randomly assigned to the control group, sacroiliac joint mobilization group, lumbopelvic stabilizing exercises group. Lumbopelvic stabilizing exercises group received lumbopelvic stabilizing exercises for 30 minutes, sacroiliac joint mobilization group received sacroiliac joint mobilization for 2-3 minutes per day and three times a week during 3 weeks period. Active balancer(SAKAI EAB-100) was used to measure equilibrium ability. All measurements of each subjects were measured at pre-experiment, after 10 days, and post-experiment. The results of this study were summarized as follows: 1. The WPL of control group, sacroiliac joint mobilization group, lumbopelvic stabilizing exercises group was no significantly differences at pre-experiment(p>.05), but significantly reduced after 10 days and post-experiment(p<.05). The results of analyzed effects of WPL was significantly reduced between experiment type of control group, sacroiliac joint mobilization group, lumbopelvic stabilizing exercises group according to pre-experiment, after 10 days, and post-experiment(p<.05). 2. The RA of control group, sacroiliac joint mobilization group, lumbopelvic stabilizing exercises group was no significantly differences at pre-experiment(p>.05), but significantly reduced after 10 days, and post-experiment(p<.05). The results of analyzed effects of RA was significantly reduced between experiment type of control group, sacroiliac joint mobilization group, lumbopelvic stabilizing exercises group according to pre-experiment, after 10 days, and post-experiment(p<.05). Conclusionally these data suggest that a 3-week SI joint mobilization and lumbopelvic stabilizing exercises improved equilibrium. Additional randomized controlled trials to more fully investigate treatment effects and factors that may mediate these effects are needed.

Background and objective: This study was carried out to investigate and analyze the preference for plant fragrance and the psychological effects of a agro-healing activity in 101 firefighters aged 39.71 ± 10.94. Methods: For the psychological evaluation, post-traumatic stress symptoms, Korean occupational stress scale short form (KOSS-SF), emotional intelligence, and job satisfaction were surveyed on the Likert scale. For the preference for plant fragrances, 20 ㎕ of commercially available essential oils from four plant species (Mentha spp., Lavandula spp., Citrus limon, C. sinensis) were absorbed into each test paper and provided to the participants. Results: The rate of post-traumatic stress symptoms was high at 37.6% of the firefighters surveyed.. C. limon fragrance had the highest preference among the four plant fragrances, followed by C. sinensis > Mentha spp. > Lavandula spp. with statistically significant difference (F = 14.256, p < .001). The lower their age, income, and position, and higher the education level, the higher the preference for plant fragrances. And the administrative group had higher preference for plant fragrances than field group. In addition, as a result of examining the correlation between job satisfaction, preference for plant fragrance, post-traumatic stress, emotional intelligence, and job stress for fire-fighters, the higher the job satisfaction, the higher the fragrance preference and emotional intelligence, and the lower the post-traumatic stress and job stress. Conclusion: Therefore, installing a garden using botanical fragrances at workplaces that firefighters can easily access will improve job satisfaction and relieve stress. It can be concluded that applying the fragrance of plants to the healing farming activities at the fire-fighter's workplace can increase the usefulness of the healing activities.

Purpose: The purpose of this study was to identify the effects of meridian massage on menopausal symptoms and Shin-Hur in middle-aged menopausal women. Method: The research design was a nonequivalent control group pre-post experimental design. The subjects of the study were middle-aged women who had had no menstruation in the last 12 months after the last menstrual bleeding. Cards of invitation on bulletin boards of several apartments were placed to recruit the subjects. The cards of invitation included: purpose of the study, eligibility criteria, method and period. Eighteen women in the experimental group and 16 women in the control group were conveniently assigned, respectively. The experimental group received 20 min meridian massage 3 times per week for 4 weeks. The menopausal symptoms and Shin-hur were measured and compared between the two groups before and after the intervention. Data were analyzed with the SPSS program by Fisher's exact test, Wilcoxon Sign Rank test, Mann Whitney U-test and Spearman's rank correlation. Result: The experimental group showed a significant decrease of menopausal symptoms (U=77.00, p=.020) and Shin-Hur (U=76.00, p=.017). There was a significantly positive correlation between menopausal symptoms and Shin-Hur (r=.497, p=.003). Conclusion: Meridian massage was effective in improving menopausal symptoms and Shin-Hur in middle-aged menopausal women. Thus it can be useful as a nursing intervention for menopausal women.

Purpose. The purpose of this study were to investigate the effects of a 12-week brisk walking program on triglycerides (TG) and apolipoprotein B (Apo B) and to compare these effects to those of a brisk walking plus diet program in middle-aged overweight/obese ($BMI{\geq}23$) Korean women with hypertriglyceridemia. Method. This analysis was done with nineteen middle-aged overweight/obese Korean women who completed either the brisk walking program (9 women) or the brisk walking plus diet program (10 women) for 12 weeks. The brisk walking consisted of walking for 20 to 50 minutes/day at an intensity of 40 to 70% of heart rate reserve (HRR) for 3 to 6 days/week. The diet consisted of 60 minutes of group education and 20 to 30 minutes of individual counseling every week. TG and Apo B were assessed pre- and post-intervention. Results. TG and Apo B decreased significantly after the brisk walking program (Z = -2.31, p = 0.021; Z = -2.59, p = 0.009). TG and Apo B lowering effects of the brisk walking program were not significantly different from those of the brisk walking plus diet program (U = 37.0, P = 0.549; U = 42.0, P = 0.842). Conclusion. Brisk walking can be an effective intervention for overweight/obese middle-aged women with hypertriglyceridemia in reducing cardiovascular risk by lowering TG and Apo B levels. Adding diet to brisk walking may have no additional significant effects on changes in TG and Apo B.

This study was designed to implement and evaluate a nutrition education program for hypertensive patients aged between 50 and over. Nutrition education consisted of four sessions and, 35 out of 51 patients completed all education sessions at the public health center. To assess program effectiveness (effectively), data about blood pressure, blood cholesterol, anthropometry, nutrition knowledge, eating behavior and dietary intake were collected before and after nutrition education. Data were analyzed using SAS package (ver. 9.2) and significant difference was evaluated by paired t-test, x2-test and Wilcoxon signed rank test. Blood cholesterol was significantly reduced from 200.7 mg/dL to 188.7 mg/dL after nutrition education, although there were not significant changes in blood pressure or blood triglyceride level. Weight (p < 0.05), % body fat (p < 0.001), BMI (p < 0.05) were significantly reduced, especially in women, after nutrition education. Nutrition knowledge was increased significantly (p < 0.05), and some eating behaviors such as 'having fruits & vegetables for snack' and 'having brown rice, barley rice than white rice' were improved after nutrition education (p < 0.05). Sodium intake was reduced from 3,888.9 mg/day to 3,157.4 mg/day after nutrition education (p < 0.05). Except protein and iron intakes, the nutrient intake of hypertensive patients was much below the recommended level for Koreans. Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. It appeared that nutrition education for the aged hypertensive patients was effective in reducing the percentage of % body fat and BMI, increasing the nutrition knowledge and some dietary behaviors. This nutrition education can be implemented at public health centers or senior centers for hypertensive patients.

In mammal, unfertilized oocytes remain in the oviduct or under in vitro culture, which is called "oocyte aging". This asynchrony negatively affects fertilization in pre- and post-implantation embryo development. Caffeine a phosphodiesterase inhibitor is known to rescue oocyte aging in several species. The objective of this study is to determine the cytoskeleton distribution in aged oocytes and the embryo developmental ability of aged oocytes in the present or absence of caffeine during maturation. Caffeine treatment increased the incidence of normal spindle assembly of aged oocytes (treatment, $67.57{\pm}4.11%$ aging, $44.61{\pm}6.4%$) and no significant differences compared to control group. Fluorescence values were compared using ROS (Reactive oxidation species) stain. Fluorescence values appear of control group intensity rate ($51.53.{\pm}3.80$), aging group ($68.10{\pm}5.54$) and treatment of caffeine ($45.04{\pm}2.98$). Aged oocytes that were derived from addition of caffeine to the IVM (in vitro maturation) medium had significantly increased 2-cell that developed to the blastocyst stage compared to the aging group. Blastocysts, derived from caffeine treatment group, significantly increased the total cell number compare aging ($90.44{\pm}10.18$ VS $67.88{\pm}7.72$). Apoptotic fragments of genomic DNA were measured in individual embryo using TUNEL assay. Blastocyst derived from caffeine treatment group decreased significantly the apoptotic index compared to blastocyst derived from aging group. In conclusion, we inferred that the caffeine treatment during oocyte aging can improve the developmental rate and quality in bovine embryos developing in vitro.
