Purpose - This study verified the mediating effect of volunteer activities in the influence of global citizenship consciousness on human rights sensitivity of university students majoring in business administration. Research design, data, and methodology - The survey was conducted on 172 4-year college students in G City, Korea. SPSS 23.0 program was used to perform frequency analysis, descriptive statistics analysis, correlation analysis, reliability analysis, and multiple regression analysis. In addition, path analysis was conducted to confirm the mediating effect of volunteer activities. Result - First, the "justice domain" had a statistically significant effect on human rights sensitivity. Second, the "cognitive domain" had a positive and significant effect on volunteer participation. Third, the volunteer participation of university students majoring in business administration had a positive and significant effect on human rights sensitivity. Fourth, in the relationship between global citizenship consciousness and human rights sensibility of university students, volunteer participation had a partial mediating effect. Conclusion - The period of college enrollment is an important time to establish life goals and strategies as adults. Therefore, if the university environment is built to grow into a healthy global citizen, it will help to cultivate global competence and the "sensitivity to human rights" that is more emphasized in the era of the 4th industrial revolution.

Vasoactive intestinal peptide (VIP) is a very potent dilatator and a nonadrenergic, noncholinergic (NANC) neurotransmitter or neuromodulator in the peripheral and the central nervous systems. The mechanisms of action of VIP were examined in aortic circular and in uterine longitudinal smooth muscle strips of the rat. The effects of sympathetic neurotransmitter were investigated in gastric and aortic circular muscle strips of the mouse and the rat. The effects of silver spike point, SSP, low frequency electrical stimulations of VIP, sympathetic neurotransmitter and $\beta$-endorphin were examined in plasma, serum and 24h urine from the healthy volunteer. In gastric smooth muscle strips from the mouse, adrenergic neurotransmitter norepinephrine was inhibitory effected, followed by caused phasic and tonic contraction to the, muscrine receptor agonist carbachol and acetylcholine, respectively. In urine from the healthy volunteer, both norepinephrine and epinephrine were significantly decreased in continue type and low frequency (3 Hz) of SSP electrical stimulations. The contractile responses to S-HT in uterine longitudinal smooth muscle strips of the rats were completely decreased by a VIP 1 $\mu$M. The contractile responses to PGF2$\alpha$ were not decreased by a VIP. In plasma and serum from the healthy volunteer, both VIP and $\beta$-endorphin were significantly increased in continue type and low frequency (3 Hz) of SSP electrical stimulations. Therefore, this study demonstrate that VIP has the capacity to relax vascular or gastric smooth muscles in part by stimulating the generation of NO, and silver spike point low frequency electrical stimulation has the capacity both to decrease sympathetic neurotransmitters and to increase VIP, $\beta$-endorphin.

In the Digital Transformation infrastructure at the addition to research on mental health such as depression and well-being, research on middle-aged health requires a study consisting of specific measures of cognitive health. This study used social, mental, and physical cognitive health as a sub-domain of cognitive health. The purpose of this study was to investigate the positive effects of volunteer activities on cognitive health for middle-aged women. The questionnaire survey was conducted on middle-aged women aged 40 to 59, focusing on the question "How well does cognitive health work for middle-aged women through volunteer activities?" The goal of this study is to examine the effect of volunteer activities on the cognitive health of middle-aged women and to analyze the meaning and influencing factors of volunteer activities needed to maintain the desirable life of middle-aged women and the healthy life of the elderly. The necessity to diversify and activate volunteer activities of middle-aged women was proved through the survey.

Objectives In Sasang Constitutional medicine(SCM), it is an important factor to assess the degree of cold/heat and healthy status. We purposed to check the agreement among the experts on the assessment of cold/heat and healthy status. Methods Six SCM experts and 10 healthy volunteers were recruited for this study. The SCM experts had an interviewed with each volunteer in the similar condition like that of the actual clinic. And then the expert evaluated each volunteer's cold/heat and healthy status. Intraclass correlation coefficient(ICC) was used to measure the interrater reliability and interrater agreement among the experts. Results Two volunteers are excluded due to the missing data, therefore eight persons' data (3 males and 5 females) were included in our analysis. The mean of age and BMI are 21.73(${\pm}2.32$) and 29.63(${\pm}4.66$), respectively. In health status, cold status and heat status, the ICC was 0.789, 0.904, 0.925, respectively. Conclusions We found that the assessment of cold/heat and healthy status was continued reliable among SCM experts. The assessment of cold/heat status was more consistent than the assessment of healthy status.

Purpose: The present study aimed to study the immunogenicity of the ChAdOx1 nCoV-19 vaccine in patients with hematologic malignancies. Materials and Methods: This prospective cohort study of hematology patients aimed to evaluate their antibody levels against the receptor-binding domain of the severe acute respiratory syndrome coronavirus 2 spike protein and seroconversion rates following two doses of the ChAdOx1 nCoV-19 vaccine. Between June and July 2021, we enrolled 61 patients and included 44 patients in our analysis. Antibody levels were assessed 8 and 4 weeks after the first and second injections, respectively, and compared with those of a healthy group. Results: Eight weeks after the first dose, the geometric mean antibody level was 1.02 binding antibody units (BAU)/mL in the patient group and 37.91 BAU/mL in the healthy volunteer group (p<0.01). Four weeks after the second dose, the geometric mean antibody level was 9.44 BAU/mL in patients and 641.6 BAU/mL in healthy volunteers (p<0.01). The seroconversion rates 8 weeks after the first dose were 27.27% and 98.86% in the patient and healthy volunteer groups, respectively (p<0.001). The seroconversion rate 4 weeks after the second dose was 47.73% in patients and 100% in healthy volunteers. Factors leading to lower seroconversion rates were rituximab therapy (p=0.002), steroid therapy (p<0.001), and ongoing chemotherapy (p=0.048). Factors that decreased antibody levels were hematologic cancer (p<0.001), ongoing chemotherapy (p=0.004), rituximab (p<0.001), steroid use (p<0.001), and absolute lymphocyte count <1,000/mm³ (p=0.009). Conclusion: Immune responses were impaired in individuals with hematologic malignancies, particularly patients undergoing ongoing therapy and B-cell-depleting therapy. Additional vaccinations should be considered for these patients, and further investigated.

Objective: To develop a population pharmacokinetics (PK)/pharmacodynamics (PD) model for alcohol in healthy volunteers and to elucidate individual characteristics to affects alcohol's PK or PD including dissolved oxygen. Methods: Following multiple intakes of total 540 mL alcohol (19.42 v/v%) to healthy volunteer, blood alcohol concentration was measured using a Breathe alcohol analyser (Lion SD-400 $Alcolmeter^{(R)}$). A sequential population PK/PD modeling was performed using NONMEM (ver 7.3). Results: Eighteen healthy volunteer were included in the study. PK model of alcohol was well explained by one-compartment model with first-order absorption and Michaelis-Menten elimination kinetics. $K_a$, V/F, $V_{max}$, $K_m$ is $8.1hr^{-1}$, 73.7 L, 9.65 g/hr, 0.041 g/L, respectively. Covariate analysis revealed that gender significantly influenced $V_{max}$ (Male vs Female, 9.65 g/hr vs 7.38 g/hr). PD model of temporary systolic blood pressure decreasing effect of alcohol was explained by biophase model with inhibitory $E_{max}$ model. $K_{e0}$, $I_{max}$, $E_0$, $IC_{50}$ were $0.23hr^{-1}$, 44.9 mmHg, 138 mmHg, 0.693 g/L, respectively. Conclusion: Model evaluation results suggested that this PK/PD model was robust and has good precision.

A wrist watch type wearable cardiovascular monitoring device is proposed for continuous and convenient monitoring of the patient's cardiovascular system. For comprehensive monitoring of the patient's cardiovascular system, the concurrent electrocardiogram (ECG) and arterial pulse wave (APW) sensor front-end are fabricated in $0.18{\mu}m$ CMOS technology. The ECG sensor frontend achieves 84.6-dB CMRR and $2.3-{\mu}Vrms$-input referred noise with $30-{\mu}W$ power consumption. The APW sensor front-end achieves $3.2-V/{\Omega}$ sensitivity with accurate bio-impedance measurement lesser than 1% error, consuming only $984-{\mu}W$. The ECG and APW sensor front-end is combined with power management unit, micro controller unit (MCU), display and Bluetooth transceiver so that concurrently measured ECG and APW can be transmitted into smartphone, showing patient's cardiovascular state in real time. In order to verify operation of the cardiovascular monitoring system, cardiovascular indicator is extracted from the healthy volunteer. As a result, 5.74 m/second-pulse wave velocity (PWV), 79.1 beats/minute-heart rate (HR) and positive slope of b-d peak-accelerated arterial pulse wave (AAPW) are achieved, showing the volunteer's healthy cardiovascular state.

The purpose of this study is to investigate voluntary activities of the elderly. Two hundred and eight older Cheongju residents were selected, and a questionnaire was used to collect data. The results are as follows: The number of participants in voluntary activities was relatively small. The main reasons for negative attitudes toward voluntary activities were significantly different according to sex, educational level, marital status, health status, economic level, religion, and life satisfaction. By using a cluster analysis, the elderly could be divided into four groups. Among them, a group with positive attitudes participating in volunteer activities was more likely to include males or those educated, healthy, and affluent. Based on the results of this study, it is revealed that participating in volunteer activities provides problem solutions and self development for elderly people.
