This descriptive study was conducted to identify the factors affecting the psychological well-being of nursing students. A questionnaire survey was conducted on 298 nursing college students attending two universities in G city from April 10 to May 9, 2018. The research tools were used 27 items of Professor Trust Scale, 25 items of emotional regulation, 25 items of Connor-Davison Resilience Scale, and 18 items of psychological well-being scale. psychological well-being was significant different according to gender(p=.019), grade(p=.011), motivation of choosing a nursing(p=.003), major satisfaction(p<.001), stress of clinical practice(p=.002), and current health status(p<.001). There were significant positive correlations between psychological well-being and professor trust, active emotion regulation, support-seeking emotion regulation, and ego-resilience and negative correlation between psychological well-being and avoidant-distractive emotion regulation. The results of multiple regression analysis are as follows. Factors influencing the psychological well-being of nursing students were ego-resilience, support-seeking emotion regulation, avoidant-distractive emotion regulation, major satisfaction and these variables explained the psychological well-being by 55.0%(F=30.92, p<.001). It is necessary to develop a curriculum/comparative programs and student coaching plans for improving ego-resilience which is the most influential variable. Also internal or environmental and social support should be strengthened so that negative emotions caused by various causes can be efficiently managed.

Cognitive impairment responses are important research topics in the study of degenerative brain diseases as well as in understanding of human mental activities. To compare response to scopolamine (SPL)-induced cognitive impairment, we measured altered parameters for learning and memory ability, inflammatory response, oxidative stress, cholinergic dysfunction and neuronal cell damages, in Korl:ICR stock and two commercial breeder stocks (A:ICR and B:ICR) after relevant SPL exposure. In the water maze test, Korl:ICR showed no significant difference in SPL-induced learning and memory impairment compared to the two different ICRs, although escape latency was increased after SPL exposure. Although behavioral assessment using the manual avoidance test revealed reduced latency in all ICR mice after SPL treatment as compared to Vehicle, no differences were observed between the three ICR stocks. To determine cholinergic dysfunction induction by SPL exposure, activity of acetylcholinesterase (AChE) assessed in the three ICR stocks revealed no difference of acetylcholinesterase activity. Furthermore, low levels of superoxide dismutase (SOD) activity and high levels of inflammatory cytokines in SPL-treated group were maintained in all three ICR stocks, although some variations were observed between the SPL-treated groups. Neuronal cell damages induced by SPL showed similar response in all three ICR stocks, as assessed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, Nissl staining analysis and expression analyses of apoptosis-related proteins. Thus, the results of this study provide strong evidence that Korl:ICR is similar to the other two ICR. Stocks in response to learning and memory capacity.

Recently, the form of education has changed from one-way to two-way and mutual exchange rather than the existing one-way order form, and accordingly, it is necessary to consider creating a suitable learning environment for each type of education. The basic form of education consists of the delivery of knowledge, that is, the delivery of knowledge by teachers to education consumers through voice delivery, so the sound environment is considered an essential factor in creating a pleasant learning environment. The indoor sound environment is very closely related to the mental stress of the inmate, so the quality level of education will also change greatly depending on whether or not the appropriate sound environment is created. However, the importance of the sound environment in educational facilities such as classrooms has not been highlighted due to the lack of research and related laws on the sound environment. Therefore, in this study, auditory tests were conducted using the auralization based on the physical acoustic performance data presented in the preceding study. Through this, we wanted to verify the validity of this research by analyzing the subjective acoustic performance satisfaction of the occupants due to the improvement of the physical acoustic performance. Based on these research results, it is estimated that the improvement of the sound environment of educational facilities through remodeling in the future will be possible to verify whether the sound environment suitable for educational facilities is created only after the analysis stage on the improvement of subjective sound performance as well as physical sound performance.

This study was undertaken to determine the degree of quality of life, and factors influencing osteoarthritis in hypertensive elderly 65 years or older patients, using data from the 7th National Health and Nutrition Survey 2018. Totally, 843 subjects were included from a national sample. The SPSS WIN 26.0 program was used to analyze complex samples by applying the Rao-Scott chi-square test, t-test, and multiple regression analysis. Results indicate that quality of life of the hypertensive group with osteoarthritis is significantly lower than the group with only hypertension (t=5.07, p<0.001). Factors affecting the decrease in quality of life of the hypertensive group were age, subjective health status, and activity restrictions, and the explanatory power was 46.1% (F=12.33, p<0.001). In the hypertensive group with osteoarthritis, the effective factors included gender, cohabitation status, economic activity, subjective health status, activity restriction, body mass index, sleep time, stress perception, and depression, and the explanatory power was 44.6% (F=99.82, p<0.001). Subsequent studies showed that in order to improve the quality of life of hypertensive seniors, intervention programs are required to actively accommodate health conditions and minimize activity restrictions. In addition, for the elderly with osteoarthritis and hypertension, it is necessary to include exercise and nutrition education for body mass index management, and the development and intervention of multidisciplinary participation programs to strengthen mental health.

The purpose of this study was to develop a measuring tool for the health promotion behavior of Korean nurses. This would address the lack of a proven tool that reflects the nature of the nurses' nursing environment. This study was conducted on 530 nurses from January to December 2019. A literature review and focus group interview were conducted, data analysis was carried out to measure validity and reliability, and the conceptual framework was constructed by applying the IMB model. Five factors namely self-concept (2 questions), hospital life management (4 questions), knowledge and information regarding health (5 questions), physical and mental stress management (3 questions), and work adaptation (2 questions) were framed into 16 questions. The model fit was 346.23 (��<.001), Parsimonious Normed Fit Index (PNFI) was 0.60, and Parsimonious Comparative Fit Index (PCFI) was 0.63, which met the acceptance criteria, and the Root Mean Square Error of Approximation (RMSEA) was 0.10. Goodness of Fit Index (GFI) was 0.88, Comparative Fit Index (CFI) was 0.85, and Incremental Fit Index (IFI) was 0.85 which were found to be acceptable as per the applicable standards. All items had a Cronbach's �� score of .85, which ensured stable reliability. The nurse's health promotion behavior measurement tool developed in this study will be used to measure the nurse's health promotion behavior in terms of nursing practice which will help in understanding the broad contours of this behavior.

Background: Due to the emergence of new diseases such as COVID-19, an increasing number of people are struggling with stress and depression. Interest is growing in forest-based recreation for physical and mental relief. Objectives: A prediction model equation using meteorological factors and data was developed to predict the quantities of medicinal substances generated in forests (monoterpenes) in real-time. Methods: The concentration of phytoncide and meteorological factors in the forests near Chuncheon in South Korea were measured for nearly two years. Meteorological factors affecting the observation data were acquired through a multiple regression analysis. A model equation was developed by applying a linear regression equation with the main factors. Results: The linear regression analysis revealed a high explanatory power for the coefficients of determination of temperature and humidity in the coniferous forest (R²=0.7028 and R²=0.5859). With a temperature increase of 1℃, the phytoncide concentration increased by 31.7 ng/Sm³. A humidity increase of 1% led to an increase in the coniferous forest by 21.9 ng/Sm³. In the deciduous forest, the coefficients of determination of temperature and humidity had approximately 60% explanatory power (R²=0.6611 and R²=0.5893). A temperature increase of 1℃ led to an increase of approximately 9.6 ng/Sm³, and 1% humidity resulted in a change of approximately 6.9 ng/Sm³. A prediction model equation was suggested based on such meteorological factors and related equations that showed a 30% error with statistical verification. Conclusions: Follow-up research is required to reduce the prediction error. In addition, phytoncide data for each region can be acquired by applying actual regional phytoncide data and the prediction technique proposed in this study.

Recently, nonsuicidal self-injury (NSSI) has been increasing considerably in school counseling. According to the Youth Counseling and Welfare Development Institute, the number of counseling support for NSSI adolescent in 2018 was more than three times higher than the previous year, and the average time when NSSI behavior first appeared was 12.43 years old. As such, adolesnect NSSI continues to increase in recent years, and the age is also gradually decreasing. Nevertheless, research on the motives and characteristics of NSSI among domestic adolescents is still insufficient. This may be attributed to the difficulty of conducting research because self-injury behavior is secretly performed. However, it is also true that this reality has another limitation in the school field, which urgently requires counseling intervention and prevention of students' mental health problems. In addition, counseling for self-injury in the school scene is the biggest cause of exhaustion for counselors because they are under very great stress to cope with repeated self-harm in the dual role of counselors and teachers in school situations. Therefore, this study examines the causes and characteristics of involuntary self-injury through previous research analysis, and examines various difficulties experienced as a school counselor, as well as the effective intervention method of non suicidal self-injury in school counseling.

The purposes of the study is to classify the psychological characteristics of gamblers using by latent profile analysis and to identify the consequences according toof the latent profiles. The subjects of the study are 473 adults gamblers who responded to a online survey about gambling patterns, basic psychological needs(BPNs), and mental health status(MHS) such as stress, depression, and anxiety. Using latent profile analysis known as the person-centered analysis, the results showed that psychological characteristics of gamblers were classified into three groups: 'Lower MHS-BPNs', 'Middle MHS-BPNs', and 'Upper MHS-BPNs'. Also, the as outcome variable, levels of problematic gambling(KCPGI) showed significant differences across the latent profiles such as Problem gambling(M=11.393) on 'Lower MHS-BPNs', Moderate-risk gambling(M=4.277) on 'Middle MHS-BPNs' and Low-risk gambling (M=1.718) on 'Upper MHS-BPNs'. Overcoming the limitations of variable-centered analysis in the existing studies, this study providesreveals new insights onin the psychological characteristics of gamblers and how different latent profiles of gamblers may be in theirdistinct levels of problematic gambling. Finally, limitations of the study and future directions for research on gambling problems are discussed.

Walkability is an indicator of how much pedestrians are willing to walk and how well a walking environment is created. As walking can promote pedestrians' mental and physical health, there has been increasing focus on improving walkability in different ways. Thus, plenty of research has been undertaken to measure walkability. When measuring walkability, there are many objective and subjective variables. Subjective variables include a feeling of safety, pleasure, or comfort, which can significantly affect perceived walkability. However, these subjective factors are difficult to measure by making the walkability index more reliant on objective and physical factors. Because many subjective variables are associated with human emotional states, understanding pedestrians' emotional states provides an opportunity to measure the subjective walkability variables more quantitatively. Pedestrians' emotions can be examined through surveys, but there are social and economic difficulties involved when conducting surveys. Recently, an increasing number of studies have employed physiological data to measure pedestrians' stress responses when navigating unpleasant environmental barriers on their walking paths. However, studies investigating the emotional states of pedestrians in the walking environment, including assessing their positive emotions felt, such as pleasure, have rarely been conducted. Using wearable devices, this study examined the various emotional states of pedestrians affected by the walking environment. Specifically, this study aimed to demonstrate the feasibility of monitoring biometric data, such as electrodermal activity (EDA) and heart rate variability (HRV), using wearable devices as an indicator of pedestrians' emotional states-both pleasant-unpleasant and aroused-relaxed states. To this end, various walking environments with different characteristics were set up to collect and analyze the pedestrians' biometric data. Subsequently, the subjects wearing the wearable devices were allowed to walk on the experimental paths as usual. After the experiment, the valence (i.e., pleasant or unpleasant) and arousal (i.e., activated or relaxed) scale of the pedestrians was identified through a bipolar dimension survey. The survey results were compared with many potentially relevant EDA and HRV signal features. The research results revealed the potential for physiological responses to indicate the pedestrians' emotional states, but further investigation is warranted. The research results were expected to provide a method to measure the subjective factors of walkability by measuring emotions and monitoring pedestrians' positive or negative feelings when walking to improve the walking environment. However, due to the lack of samples and other internal and external factors influencing emotions (which need to be studied further), it cannot be comprehensively concluded that the pedestrians' emotional states were affected by the walking environment.

This study investigates the current situation of medical technologists for blood collection, which is considered the most important step for diagnosis. The survey enrolled 650 medical technologists working in hospitals and medical check centers in Busan, Ulsan, and Gyeongnam. We found that each medical technologist performed blood collection for about 100 patients. There was more than one blood collection failure per day, with more than one case of pain and filing of civil complaints per year. Hence, there was a high work burden on the medical technologists. Cases where a medical technologist was stabbed with a used needle occurred more than once a year, and about 15% of them received infection control and treatment because of stab wounds. Additionally, more than half of the participants suffered from musculoskeletal disorders and mental stress due to blood collection work. Unlike administering intravenous and intramuscular injections using the same needle, no fee is charged for blood collection. Based on the results of this study, it will be possible to improve the safety and rights of medical technologists by calculating the actual fee for blood collection work and assigning a relative value score.
