Increasing life expectancy leads to a rise in the prevalence of aging-related mental diseases and a concomitant increase in the financial and societal pressures related to their prevention and management. This issue is attracting increasing attention from researchers. Therefore, this study aimed to determine whether a healing program in a forest environment is effective for improving cognitive function, depression, anxiety, and stress in elderly people. A nonequivalent control group pretest-posttest design was used. The experimental group consisted of 18 males and females aged 60 to 80 years who participated in a forest healing program for seven days, while the comparison group comprised 10 people with similar demographics. For the process of data analysis, this study performed a cross-analysis to determine the homogeneity of the data and carried out the Wilcoxon signed-rank test, a nonparametric statistical test, to verify the significance of each group. Participation in the forest healing program led to a significant improve-ment in cognitive function (p=0.030). The levels of depression decreased, but this result was not statistically significant. The levels of anxiety decreased significantly (p=0.004). The mean cortisol score, a measurement of stress, decreased, but it was not statistically significant. These findings confirmed the effectiveness of this program for improving certain mental conditions of elderly people, and affirmed that the use of long-term forest healing programs can be expected to alleviate national pressures created by aging societies.

Purpose: This study aims to determine the correlation between the effects of contract-relax-antagonist-contract (CRAC) and contract-relax (CR) forms of proprioceptive neuromuscular facilitation (PNF) stretching on balance during single-leg standing in elderly people. Methods: The participants were 20 elderly people in healthy condition and divided equally into two groups: the CRAC stretching group and the CR stretching group. Subjects were made to walk on a treadmill for 6 minutes before the stretching as a warm-up. CR and CRAC stretching were performed on the soleus. The dependent variables used to assess single-leg standing balance were overall stability(OSI), anterior/posterior(A/P) movement, and medial/lateral(M/L) movement. The statistical methods used to assess the differences between groups were verified using the Mann-Whitney U test and the Wilcoxon signed-rank test. Results: The CRAC group had significantly increased OSI, A/P and M/L after the PNF stretching intervention (p < 0.05). The CR group had significantly increased OSI and A/P after the PNF stretching intervention (p < 0.05), but M/L did not significantly increase (p > 0.05). There was no significant difference in stretching between CRAC and CR (p > 0.05). Conclusion: The results of this study revealed that CR and CRAC PNF stretching improved single-leg standing balance. CARC stretching before exercise is helpful for elderly people, as it improves balance.

The COVID-19 pandemic has hurt the economy and negatively impacted all enterprises' financial performance. The COVID-19 pandemic has put a strain on global manufacturing capacity and supply chains, and it is also the pandemic that has given up new opportunities for the logistics industry to develop as e-commerce has developed. By analyzing the financial performance of logistic firms listed on the Vietnam Stock Exchange, this study tries to quantify those consequences. A total of 114 logistic companies were included in the study's sample. The Wilcoxon Signed Rank Test was performed to test the difference between some ratios in 2019 and 2020. This study found that the financial performance of 114 logistic firms listed on the Vietnam stock exchange has not improved. The data show that during the COVID-19 pandemic, the leverage ratio increased while the profitability and efficiency ratios decreased. The liquidity ratio did not show any significant differences. On the contrary, these businesses' performance, such as returns on assets, receivable turnover, and leverage, has decreased. The COVID-19 had a global impact on supply chains, therefore export activity and international transportation were badly hampered, with only a few domestic logistic enterprises growing.

Objective: This study designed an Augmented Reality-based intervention program for children with conflicted shyness and examined its effects on social avoidance motivation and preference for being with others. Methods: Sixteen six-year-old children were randomly assigned to either the experimental or control group. The experimental group participated in a six-week AR-based program. Both teachers and children rated social avoidance motivation and preference for being with others to evaluate the program's effectiveness. Data were analyzed using the Wilcoxon signed-rank test and the Mann-Whitney U test. Results: Social avoidance motivation decreased only for the experimental group. Conversely, the control group showed increased motivation scores as reported by the children. The preference for being with others increased in the experimental group based on teacher reports. For the control group, preference scores reported by teachers and children were maintained and decreased, respectively. Conclusion/Implications: This study highlights the effectiveness of the intervention in reducing social avoidance motivation and maintaining a preference for being with others in children experiencing conflicted shyness. Furthermore, the use of AR technology provided a psychologically safe environment for them to initiate social interactions without fear of negative evaluation, highlighting its potential as a primary intervention tool for this population.

Purpose: The purpose of this study was to identify the effects of general exercise after blood flow restriction on trunk muscles thickness in children with spastic cerebral palsy. Methods: Twenty children with cerebral palsy were assigned randomly to an experimental (n = 10) or a control (n = 10) group. The experimental group performed general exercise after blood flow restriction, while the control group performed general exercise alone. The study used an ultrasonic instrument to measure trunk muscles thickness. The Wilcoxon signed-rank test was used to determine differences before and after treatment, and the Mann-Whitney U test was used to determine differences between treatment groups. Results: From a comparison within the groups, the experimental and control groups showed significant difference in trunk muscle thickness after the experiment (p < 0.05). In a comparison between the two groups, the experimental group showed more significant difference in trunk muscle thickness than the control group (p < 0.05). Conclusion: Based on these results, general exercise after blood flow restriction effectively improves trunk muscle thickness in children with cerebral palsy.

타액에 존재하는 여러 항균물질은 상호작용을 통하여 부가적이거나 상승작용을 나타내고 때로는 저해작용을 나타내는 것으로 알려져 있다. 본 연구는 in vitro 상에서 lysozyme과 peroxidase 사이의 상호작용을 효소활성 측면에서 조사하고자 시행되었다. Lysozyme과 peroxidase의 상호작용은 hen egg-white lysozyme(HEWL)과 bovine lactoperoxidase(bLP)를 혼합하는 방법으로 조사되었고, peroxidase system이 lysozyme에 미치는 영향은 potassium thiocyanate와 hydrogen peroxide를 추가적으로 첨가하는 방법으로 조사되었다. Lysozyme 활성은 Micrococcus lysodeikticus 기질용액의 혼탁도 변화를 측정하는 방법으로 측정되었고, peroxidase 활성은 NbsSCN 법으로 측정되었다. Wilcoxon signed rank 법을 이용하여 lysozyme과 peroxidase 효소활성 변화를 대조군과 비교하였다. 생리적 농도범위에서 bLP는 HEWL의 효소활성을 증가시켰으며(P < 0.05), 그 효과는 bLP의 농도증가에 따라 영향을 받았다. 하지만 HEWL는 bLP의 효소활성에 영향을 주지 못하였다. Thiocyanate는 HEWL의 효소활성에 영향을 주지 못하였고, potassium thiocyanate와 hydrogen peroxide를 추가한 peroxidase system도 HEWL 효소활성의 추가적인 상승을 유도하지는 못하였으며, hydrogen peroxide의 농도변화도 영향을 미치지 못하였다. 본 연구의 결과는 타액 항균 물질을 포함하고 있는 구강건강용품이나 구강에서 lysozyme과 peroxidase의 상호작용을 이해하는데 필요한 중요한 정보를 제공해준다.

본 연구는 뇌졸중 환자에게 제공한 음악요법이 우울과 재활 동기에 미치는 효과를 규명함으로써 음악요법을 뇌졸중 환자의 간호중재방법으로 활용하기 위한 근거를 마련하고자 시도되었다. K병원에 뇌졸중 진단으로 입원한 33명을 대상으로 취침 전 30분 동안 사전에 선정된 10곡의 음악을 3일간 듣게 하였다. 그 결과 인구사회학적 특성에서 남성 참여자(25명)가 여성(8명) 참여자에 비해 많았고 연령대는 40대와 50대가 25명(75.8%)에 달했다. Wilcoxon-signed rank 검정을 사용하여 분석한 결과 우울과 재활 동기에는 영향이 없는 것으로 나타났으나, 인지수준이 낮은 MMSE 1그룹(≤ 29)에서 음악요법이 우울감소에 효과가 있는 것으로 확인되었다. 이 결과로 음악 요법의 효과성을 높이기 위한 다양한 간호중재로 적용하는데 기초자료로 제공될 것을 기대한다.
