RESUMO
[Purpose] A scalp massage was conducted on female office workers divided into a 15 minute group and 25 minute group and its effect on stress hormone, blood pressure and heart rate was analyzed in order to provide a theoretical rationale to apply scalp massage as stress therapy. [Subjects and Methods] A scalp massage was applied to 34 female office workers twice a week for a total of 10 weeks; the subjects were classified into 15â min., 25â min. and control groups, and their stress hormone levels, blood pressure and heart rate were evaluated. [Results] Significant differences in norepinephrine, cortisol and blood pressure (SBP & DBP) were found in terms of interaction by time interval and between groups. [Conclusion] As a result of applying scalp massage to female office workers for 15 and 25 minutes, positive effects were observed on stress hormone, blood pressure and heart rate. Therefore, scalp massage can be used for stress control with no spatial or time limit.
RESUMO
We aimed to identify the level of stress, ego-resiliency (ER), and coping strategies of university students during the onset of coronavirus disease 2019 (COVID-19) and examine the mediating role of ER in the relationship between stress and coping strategies (e.g., problem-solving, social support seeking, and avoidance). We analyzed responses from 160 university students and found that problem-solving was the most common coping strategy (26.02 ± 4.65), followed by social support-seeking (25.08 ± 5.23), and avoidance (19.21 ± 3.78). ER was negatively associated with stress and showed a mediating effect on the relationship between stress and social support, and stress and problem-solving coping strategies. These findings indicate that ER helps decrease stress caused by the pandemic among university students and should be considered a significant factor for developing adaptive stress coping strategies.

BACKGROUND: This study investigated depression, problematic alcohol use, and non-suicidal self-injury (NSSI) of university students in Korea during COVID-19 lockdown and evaluated the moderating effect of problematic alcohol use in the relationship between depression and NSSI. METHODS: In this descriptive cross-sectional study, 234 Korean university students' data were used to analyze the relationship between depression and NSSI and the moderating effect of problematic alcohol use. To analyze the moderating effect, Hayes PROCESS macro (model 1) was used. RESULTS: Of the participants, 69.7% were problematic alcohol drinkers and 58.1% were binge drinkers. Depression and NSSI scores were 13.948 and 0.901, respectively. Of the participants, 33.3% had experienced NSSI for 6 months. Depression was positively associated with NSSI among university students. Furthermore, problematic alcohol use had a conditional moderating effect on the relationship between depression and NSSI. CONCLUSIONS: Problematic alcohol use had conditional moderating effects on the relationship between depression and NSSI. Additionally, since the COVID-19 pandemic is ongoing, to prevent NSSI, health care professionals in the university should screen students with problematic alcohol use and depressive symptoms.
RESUMO
BACKGROUND: Recently, there has been a trend that cigarette smoking rate in Asian and Africa adults has increased while the age group to start smoking has decreased gradually. This study aimed to investigate the relationships between lifetime smoking and hypertension, diabetes, obesity, waist measure, fasting blood pressure and food consumption, in order to look into health status depending on smoking status in Koreans. METHODS: Totally, 1075 men and 697 women with no disease participated in this study, in which one-way ANOVA was conducted by using SPSS version 18.0 for statistical process. The level of statistical significance was 0.05. RESULTS: As a result of analysis on relationship between lifetime smoking and hypertension, obesity and diabetes, statistically significant differences were revealed.Lifetime smoking was found to be significantly associated with increased waist measure, higher level of fasting blood sugar, and more ingestion of nutrients (carbohydrate, fat, and protein). CONCLUSION: Increased amount of lifetime cigarette smoking was shown to negatively influence various health factors, which might become to be a drive to cause diseases. Therefore, method to improve health factors must be sought for via education and campaign to control an amount of cigarette smoking in Korean adults.
RESUMO
PURPOSE: This research was conducted to provide basic information about the effects of aerobic exercise on physiological change in middle-aged obese women according to differences of beta 3-adrenergic receptor polymorphisms. METHOD: Twenty-nine middle aged obese women with over 30%BMI were divided into three groups according to beta 3-adrenergic receptor gene polymorphism [Variable Group (VG):9, Normal Group (NG):10, Control Group (CG):10]. The VG and NG groups performed walking at 50% exercise intensity for 30 minutes a day, 4 days a week, for 12 weeks. The data was analyzed using the SPSS program. RESULT: The level of leptin, insulin and % body fat in the VG and NG groups was significantly lower than those of the CG after 12 weeks. In addition, the level of HDL-C in the VG and NG was significantly higher than that of the CG after 12 weeks. However, TC, TG and body weight between groups didn't appear significant at the end of 12 weeks. CONCLUSIONS: Aerobic exercise didn't cause differences in persons with differing beta 3-adrenergic receptor gene polymorphisms, but aerobic exercise affected the physiological change in middle-aged obese women. The findings suggest that aerobic exercise is a desirable nursing intervention for obesity control in middle-aged obese women.

Two-photon absorption properties of 1,4-bis{4'-[N,N-bis(6''-trimethylammoniumhexyl)amino]styryl}benzene tetrabromide (C1) and its inclusion complexes (ICs) with cyclodextrins (CDs) have been studied. Upon complexation with CDs, the absorption spectra of C1 showed a slight red shift, whereas the emission spectra showed a blue shift with concomitant increase in the fluorescence quantum efficiency. A Stern-Volmer study using K(3)Fe(CN)(6) as a quencher revealed significant reduction in the photoinduced charge transfer quenching, in accord with the IC formation. Comparison of the spectroscopic results reveals that C1 forms increasingly more stable ICs in the order C1/beta-CD < C1/gamma-CD < C1/(3gamma:beta)-CD (gamma-CD/beta-CD 3:1, mole ratio). Moreover, the two-photon action cross section of C1 increased from 200 GM for C1 to 400 GM for C1/beta-CD, 460 GM for C1/gamma-CD, and 650 GM for C1/(3gamma:beta)-CD, respectively. Furthermore, the two-photon microscopy images of HeLa cells stained with C1 emitted strong two-photon excited fluorescence in the plasma membrane. These results provide a useful guideline for the development of efficient two-photon materials for bioimaging applications.
