The purpose of this study was to investigate the relationship between the self-efficacy and intention to use for digital health devices by middle-aged and aged groups. We conducted the frequency analysis, T-test analysis, and linear regression analysis using the 2019 Korean Senior Technology Acceptance Survey. The analysis results are as follows. First, the group of the middle-aged had higher score of the intention to use for digital health devices than the group of the elderly. Second, the group of the middle-aged group also had higher self-efficacy than the group of the elderly. Lastly, it was found that the relationship between the self-efficacy and intention to use was not significant in the middle-aged group. However, the relationship between the self-efficacy and intention to use in the elderly group had a positive influence. We suggested that the differentiated strategy is needed to promote the utilization of digital health devices for middle-aged and aged. This study is expected to be a fundamental study of digital health devices and suggest the research model including the usefulness, ease of use, and anxiety.

Due to the high incidence of cancer and cancer-related mortality in Korea, there is increased concern and psychological anxiety about this disease, leading to increasing numbers of cancer studies. Despite these, the trend of the cancer incidence rate has shown a significant increase. The detection of colorectal cancer, which has a high incidence rate, often tends to be delayed, causing a high mortality rate. Therefore, the prevention of colorectal cancer has become an important emergent issue. The cause of this cancer has not been confirmed. However, it may be attributable to westernized dietary patterns, which include consuming a high quantity of red meat. Consumption of dietary fiber promotes the production of butyrate short-chain fatty acids by enteric bacteria. In the treatment of cancer, anticancer medications have been shown to lead to the apoptosis of tumor cells, and a strong relationship between apoptosis mechanisms of tumor cells and cancer treatment has been confirmed. The results of many studies have confirmed that butyrate can directly promote the apoptosis of colorectal cancer cells. Therefore, increased consumption of dietary fiber, which promotes the production of butyrate shortchain fatty acids, can be expected to have an effect on the prevention and treatment of colorectal cancer.

The purpose of this study is to reduce the anxiety factors of fires by following evacuation tips in case of fire in an apartment household. This study analyzed the moderating effects of the control offices' competence in control on safety awareness and fire response. The study results were as follows. First, the residents and control staff's safety awareness had a positive effect on the fire response performance. This indicates that the higher the residents and control staff's safety awareness level, the higher the fire responsive performance. Second, the higher the control offices' control competence level, the better the apartment residents and control staff's safety awareness had a positive effect on the fire response performance. These results indicate that the higher the control office heads' leadership, the higher the apartment residents' housing satisfaction and that the more communicative the control office heads' attitude toward the residents, the better their attitude had a positive effect on the fire response performance. Lastly, the control offices' control competence was analyzed to have a moderating effects on the effect of the apartment residents and control staff's safety awareness level on the fire response performance. These results showed that the change in the model's R² value showed an increasing trend in stages as the value increased more in the stage 2 than the stage 1 and even more in the stage 3 with the interaction terms of the moderating variables added. For this reason, the control offices' control competence which was a moderating variable was analyzed to have a moderating effect on the effect of residents and control staff's safety awareness level on the fire response performance.

We propose to designs and to implements a robot analyzing the risk of occurrence of mental disorder of single-person households' workers through the facial expression-detecting system. Due to complex social factors, the number and proportion of single-person households continues to increase. In addition, contrast to the household of many family members, the prevalence of mental disorder among single-person household varies greatly. Since most patients with mental can not detect the disease on their own, counseling and treatment with doctors are often ignored. In this study, we design and implement a robot analyzing the risk of mental disorder of single-person households workers by constructing a system with Q.bo One, a social robot created by Thecorpora. Q.bo One is consisted of Arduino, ar raspberry pie, and other sensors designed to detect and respond to sensors in the direction users want to implement. Based on the DSM-5 provided by the American Psychiatric Association, the risk of mental disorder occurrence was specified based on mental disorder. Q.bo One analyzed the facial expressions of the subjects for a week or two to evaluate depressive disorder, anxiety disorder. If the mental disorder occurrence risk is high, Q.bo One is designd to inform the subject to counsel and have medical treatment with a specialist.

This study examines the relationship between retirement preparation, positive psychological capital and successful aging for retirees and retirees, promotes successful aging of retirees and retirees, and increases positive psychological capital to increase desirable retirement time. I want to find a direction I can have. This study was conducted on 537 retirees and retirees who were preparing for retirement or retired from across the country as a structural relationship analysis, and the data collection period was from April 1 to April 20, 2019. As for the data, frequency analysis, correlation analysis, and structural relationship analysis were performed using SPSS 20.0 and AMOS 9.0. As a result of the study, retirement preparation of retirees and retirees had a negative relationship with successful aging, and retirement readiness had a positive effect on self-acceptance of successful aging and autonomous life as mediators of resilience of positive psychological capital and self-efficacy. This means that the positive psychological factors of positive psychological capital have a positive effect on retirees and retirees who are struggling with anxiety about retirement preparations, enabling a successful retirement life. Therefore, when operating a retirement preparation program, it is necessary to organize and operate a program that can expand positive psychological capital.

This study is a descriptive research to analyze psychosocial factors affecting health behavior adherence among community-dwelling older adults undergoing Percutaneous Coronary Intervention. Data were collected with structured questionnaires from 126 patients discharged after hospitalization from a university hospital in J city, Gyeongnam, from July 15 to October 2 in 2018, and analyzed using SPSS/WIN 21.0. The result shows that the general characteristics, such as existence of spouse, education level, subjective health status, and subjective life satisfaction, have a significant influence on health behavior adherence. The research also identifies that medical support and resilience are positively correlated with health behavior adherence. In contrast, perceived stress, 3 sub-categories from perceived stress such as, family relations, anxiety and withdrawal, poverty and finance, and depression are negatively correlated. In the multiple regression analysis, resilience, perceived stress from poverty and finance, education level, and subjective life satisfaction explained 27.9% of health behavior adherence among older adults undergoing Percutaneous Coronary Intervention. Based on the results of this study, it is necessary to develop and apply a nursing intervention program to improve the health behavior adherence of local older adults who had Percutaneous Coronary Intervention.

Crosstalk between G-protein signaling and glutamatergic transmission within the brain reward circuits is critical for long-term emotional effects (depression and anxiety), cravings, and negative withdrawal symptoms associated with opioid addiction. A previous study showed that Regulator of G-protein signaling 4 (RGS4) may be implicated in opiate action in the nucleus accumbens (NAc). However, the mechanism of the NAc-specific RGS4 actions that induce the behavioral responses to opiates remains largely unknown. The present study used a short hairpin RNA (shRNA)-mediated knock-down of RGS4 in the NAc of the mouse brain to investigate the relationship between the activation of ionotropic glutamate receptors and RGS4 in the NAc during morphine reward. Additionally, the shRNA-mediated RGS4 knock-down was implemented in NAc/striatal primary-cultured neurons to investigate the role that striatal neurons have in the morphine-induced activation of ionotropic glutamate receptors. The results of this study show that the NAc-specific knock-down of RGS4 significantly increased the behaviors associated with morphine and did so by phosphorylation of the GluR1 (Ser831) and NR2A (Tyr1325) glutamate receptors in the NAc. Furthermore, the knock-down of RGS4 enhanced the phosphorylation of the GluR1 and NR2A glutamate receptors in the primary NAc/striatal neurons during spontaneous morphine withdrawal. These findings show a novel molecular mechanism of RGS4 in glutamatergic transmission that underlies the negative symptoms associated with morphine administration.
