Objective: This research measured physiological and psychological effects of Vibroacoustic stimulation(VA) to scapular and sacrum of supine position on the mattress. Background: When vibroacoustic stimulation applies to human body, it has a positive influence on physiological and psychological effects by stimulating the organs, tissues and cells of whole body. Method: This experiment was conducted to 10 normal males in two conditions: no stimulation and vibroacoustic stimulation. No stimulation experiment was executed as a supine position for 30 minutes without any vibrational stimulus, while vibroacoustic stimulation was transmitted by the vibrational speaker, which uses 40Hz frequency. Subjects had a laser Doppler flowmeter probe in scapular, sacrum, and also had 8 channel electroencephalogram(EEG) measurement sensor in the scalp. Blood pressure and skin temperature were measured in two conditions with an underlying posture for 30 minutes. Additionally, blood flow rate and EEG were measured before and after for two minutes on two conditions. Results: According to the vibroacoustic stimulation, blood flow rate and skin temperature were increased, while blood pressure was decreased. When using vibroacoustic stimulation compared to no stimulation, blood flow rate went approximately two times higher, and skin temperature also higher 3~4 times. Furthermore, the relative alpha power of brain wave was significantly increased when we applied to vibroacoustic stimulation. Conclusion: This experiment tested the VAT embedded in mattress in two conditions. According to this experiment, VAT decreases blood pressure, improves not only a physiological effect on blood flow rate as well as skin temperature, but also psychological functions by increasing relative alpha power. Application: The results of the publishing trend analysis might help physiological and psychological effects of vibroacoustic stimulation.

Objectives: Subjective well-being is a representative indicator of quality of life. Work and life are not separated, and work itself is a part of life. The purpose of this study was to confirm the effect of psychological resources such as self-esteem, self-efficacy, GRIT, and resilience on the subjective career success and subjective well-being in dental hygienists. Methods: From November 12, 2020 to December 30, 2020, an online survey was conducted on 650 dental hygienists, and data from 630 were analyzed. For the analysis, independent two-sample t-test and one-way ANOVA were performed, and the confirmatory factor analysis and measurement model, construct validity, construct reliability, convergent validity, and discriminant validity were confirmed. This was verified using a structural equation model. SPSS 18.0 and AMOS 18.0 were used for the statistical analyses; p<0.05 were considered statistically significant. Results: The final model fit was found to be suitable. There was no significant difference in subjective career success with respect to the personal characteristics and career characteristics, except for total career and number of turnovers. There was no significant difference in subjective well-being according to personal characteristics and career characteristics. Psychological resources such as self-esteem, self-efficacy, GRIT, and resilience were significant for subjective career success (p<0.05, R²=0.637). Subjective career success was significant for subjective well-being (p<0.05, R²=0.378). Among the psychological resources, self-esteem had both direct and indirect effects on subjective well-being (p<0.05). Conclusions: Positive psychological resources, rather than external conditions, are an important prerequisite for subjective career success and subjective well-being. Thus, it is proven that work is a part of life.

This study was conducted to investigate the response of the human body to stress induced by wall recording of subway stations in the city center. The experiment was conducted as a simulation exercise, and six images were selected and produced based on Subway Line 2, a representative underground space in Seoul. The study participants included 24 male and female college students. A three-minute experiment was conducted, during which the participants were shown the control image and green wall image once each. To measure psychological status, the following measurement indicators were used: Semantic Differential, Positive Affect and Negative Affect Schedule and State-Trait Anxiety Inventory. Physiological changes were investigated by tracking participants' heart rate and blood pressure. Results showed that parasympathetic and sympathetic nerves were activated in the presence of the green wall in the subway station. The psychological evaluation analysis revealed that negative affect toward underground space decreased, while positive affect increased. This study found that the green wall in subway stations has a stable effect on the human body, both psychologically and physiologically. In the future, green walls in underground spaces can be used to reduce psychological stress and increase physiological relaxation.

Purpose: The study has been conducted to identify factors affecting the participation in leisure activities by elderly women living alone. Methods: Data were collected through a questionnaire survey among 150 elderly women in Seoul and Gyeong-gi Province. The measurement tools that were used include participation in leisure activities, perceived health status, Geriatric Depression Scale Short Form-Korea (GDSS-K), psychological well-being scale, and loneliness scale. The data were analyzed by using the Pearson correlation coefficients, t-test, analysis of variance ANOVA, and stepwise multiple regression with the SPSS/windows version 21.0 program. Results: The analysis shows that the affection for participation in leisure activities of the elderly women living alone who participated in the questionnaire survey is significant (F=14.6, p<.001). The value of the adjusted $R^2$ is 0.55, which accounts for the explanatory power of 55.4%. The predictor that has been found to have the greatest influence on the participation in leisure activities by the elderly women living alone include perceived health status, followed by monthly allowance (10,000 won), psychological well-being, economic status, religion, depression, family structure, and loneliness. Conclusion: The results suggest that in developing nursing interventions and practice for the participation in leisure activities by elderly women living alone, perceived health status, psychological well-being, depression, and loneliness should be considered.

This study investigated highschool students' brain waves on functional tasks such as a transition(F task) from equation to graph and the other transition(G task) vice versa. A total of 39 students participated in the study who attended a high school located in Gyunggi province. These students were divided into two groups, HMA and LMA by MASS test revised by Ko, & Yi (2012). The functional tasks for the stroop task to measure EEG were provided from a previous study, Seok(2015). The results indicated two groups on G tasks showed deeper and wider brain waves which demonstrated G tasks were more difficult than F tasks. However, HMA group had an effect of the non-psychological program which had given more chances on G tasks rather than F tasks within Students' Zone of Proximal Development. Also, HMA group's brain waves had more ranges in amplitude and width of waves. These results imply that the characteristics of students' brain waves with math anxiety are consistent to the previous studies.

The purpose of this study was to develop an impact force measurement device in order to facilitate the acquisition of quantitative data for the analysis of various sporting events. The device was designed to include cylindrical aluminum supports of 220 mm diameter, which allows mounting and dismounting of the device on walls and frames. In addition, a hard sponge for impact absorption, as well as 4 springs, were attached to the plate. Both were attached to prevent psychological variables and injuries. When a subject applies force on the device, accurate data about the maximum repulsive force is acquired in real time, with a lag of only 0.001 s. The device was calibrated in four steps: (1) increase, (2) increase, (3) increase-decrease, and (4) increase-decrease. The maximum relative expanded uncertainty was 0.166%, indicating that the impact force measurement was sufficiently reliable. The proposed device can be applied to various sporting situations and is expected to be useful for studying kinetics.

High temporal-resolution and accurate measurement of skin impedance locus provides useful data for the identification of the physiological/psychological changes and also the identification of acupuncture point. An impedance spectroscopy method using digitally constructed current waveform consisting of many frequency components (multiples of 1Hz) was reported3. The time resolution of the method depends on the lowest frequency used in the waveform construction, and therefore, the measurement would be faster if the lowest frequency is the higher. However, it was not clear that how many and how low frequencies must be used for the estimation of the skin impedance parameters from which the impedance locus can be drawn. This study shows the relationship between the estimation error of the impedance parameters and the frequency coverage of the spectroscopy. The results of this study are expected to serve as the reference of the frequency selection in the impedance spectroscopy.

The major goal of caring the elderly is not to cure the patient, but rather to improve or maintain the individual functional ability. With the aged population increases, there is increasing consensus among health care workers about the importance of developing a tool to measure and evaluate the health status of the elderly. As many writers is pointing out, care of the elderly embraces the spectrum of physical-social-psychological problems and an enormous number of variables could be introudeced into the health worker's routine measurement. But such an expansive approach to measurement could have disadvantages. The purpose of this study is to introduce the measurement tools of physical functioning, perhaps the most important measure required in long-term care, which are separated into three categories of measures; general physical health, ADL, IADL. It is important that all health workers who provide care to the elderly incorporate the concepts of functional health status into the routine assessments. And continuous study about reliability and validity is needed to apply those foreign tools to Korea.
