Purpose: The relationship between the staff area and the patient's private area is the key factor in designing the structure and the environmental characteristics of ward spaces in a psychiatric hospital. Recent research has found that for the purpose of treatment and securing privacy, psychiatric patients need to be in an open space of relief rather than closed confined environment and under the watch of nursing staffs. Methods: A survey at three kinds of wards in a private psychiatric hospital in Japan was conducted in October 2002. These wards include an acute ward, a psychiatric convalescence ward, and a stress care ward. All three kinds of wards have the same structure. At each ward, spatial preferences of the 145 psychiatric inpatients were surveyed and data concerning the patient's diagnostic category, symptoms, and activities of daily living were recorded. Results: The patients in the stress care ward prefer to stay in private spaces than public spaces. On the other hand, in the acute ward the patients seem to have a preference between managed public spaces where are monitored by nursing staffs and their private rooms where the nurse station is close. In addition, the patients in the psychiatric convalescence ward spend most of their time in the public space, such as the hallways or the day room. Implications: Base on this research, the spaces at the acute ward that could be monitored by the nursing station serves effectively as a safety space for patients was concluded. However, in the stress care ward, the patients may perceive the monitoring by the nursing staff as interruption or nuisance to their relaxation. In order to design an ideal healing environment for psychiatric patients in psychiatric ward, it is important to consider how environmental characteristics of space affect the environmental sense of patients in each ward.

When a traumatic subject experiences extreme stress, various psychiatric problems, including PTSD, can occur if they do not respond appropriately. In addition, non-war soldiers who experience life-threatening events while serving in the military may experience severe and chronic PTSD symptoms. However, there are still insufficient domestic studies on what traumatic events soldiers are exposed to and how much PTSD symptoms they experience. Therefore, this study provides a method that can be used as basic data for PTSD and psychological support of military service personnel by identifying trends in domestic research. Furthermore, it studies PTSD not only of soldiers but also of 'civilians' who have experienced combat, and provides symptomatic treatment and relief programs to civilians according to the difference in PTSD between general trauma and war trauma. It is expected that these studies will increase military confidence and enable the military to play a leading role in war trauma PTSD research and prevention, treatment and mitigation.

Purpose: Music therapy helps alleviate anxiety, depression, and pain for cancer patients, contributing to stress relief. With such advantages, music therapy is applied across a broad spectrum of treatment areas, including mental disorders, developmental disabilities, and conditions affecting the elderly. It has been shown to enhance the quality of life for terminally ill cancer patients. Recent research has revealed its positive effects in boosting immune function and resilience. In light of these findings, the author conducted a study to investigate patient satisfaction with music listening. Materials and Methods: First, a survey was conducted with 30 individuals to inquire about the perceived necessity of listening to music in a waiting area. Next, participants were asked whether listening to music could contribute to psychological stability. Finally, preferences for music genres and satisfaction with music listening were assessed with a sample of 20 individuals. Results: In terms of the perceived necessity of listening to music in the waiting area, 28 out of 30 individuals, or 93%, expressed agreement. Regarding the belief that music listening could contribute to psychological stability, 28 out of 30 individuals, or 93%, believed that it would indeed help with stability. When it comes to preferred music genres, 4 individuals (13%) favored classical music, 2 individuals (6%) preferred traditional Korean music, 2 individuals (6%) enjoyed trot music, and 20 individuals (66%) had no specific genre preference. As for music listening satisfaction, 17 out of 20 individuals, or 85%, reported being satisfied. Conclusion: When patients visit the hospital, stress can increase due to concerns about their medical conditions. To address this, providing a variety of music genres at the hospital has been effective in reducing patient stress and promoting psychological stability.

The purpose of this study is to relieve the residual stress of Al6061 using cryogenic heat treatment. Experimental T6 and cryogenic heat treatments were carried out to define the convective heat-transfer coefficient, which was then applied in the finite-element method (FEM) to predict the residual stress. The predicted residual stress was compared with the residual stress measured by X-ray diffraction (XRD), and the results were in good agreement. The mechanical properties were estimated by measuring the electrical conductivity and hardness. In addition, the size and formation of the precipitations were observed by TEM and XRD analysis for both T6 and cryogenic heat treatments. The effects of the cryogenic heat treatment on the residual stress, mechanical properties, and precipitation of Al6061 alloys were thus confirmed.

Purpose: This study investigated the effects that music therapy by self-selected music listening has on the affect and stress relief in adult patients who have been diagnosed with terminal cancer by pain level. Methods: Participants were 20 terminally ill cancer patients who were over 18 years old and were admitted to the hospice and palliative care unit of a local hospital. At the beginning of each session, participants selected music of their choice. Each participant had a total of six 30-minute music listening sessions. Participants were grouped into two according to their self-rated perceived pain scores on the visual analogue scale and numeric rated score: 5 and above and less than 5. Each participant completed a questionnaire on their affect state before and after each session and a questionnaire on their stress level before the first session and after the last session. Further analysis was performed to compare differences between the two groups according to pain level. Results: There were significant differences in patients' affect before and after each session (P<0.001) and stress level before and after the therapy (P=0.001). Conclusion: In this study, self-selected music listening had positive effects on terminal cancer patients' affect and stress regardless of perceived pain level. Therefore, self-selected music listening can be used as an appropriate intervention to improve affect and reduce stress in terminal cancer patients in the hospice and palliative care unit.

Due to the coronavirus pandemic, interest in outdoor leisure activities is growing. Among outdoor leisure activities, marine sports can be seen as having good conditions to enjoy in Korea. In the case of yachting among marine sports, a number of yacht experience programs have recently been operated centered on Gwanganli and Suyeong Bay in Busan. This yacht experience is an attractive tourism product that can be enjoyed casually, and can bring stress relief to many users. This study tried to verify the effect of the attractiveness of the yacht experience on the stress recovery based on the tourists' experiences using the yacht experience tour. In addition, we tried to verify the intention of revisiting the yacht experience or sharing it with others through SNS through this stress recovery. In addition, as a moderator variable, the difference between the MZ generation and other generations, which use SNS more actively than other generations, was presented and its significance was verified. The survey of this study was conducted online for tourists who experienced yacht experience in Busan. As a result of the analysis, among the attractive factors of the yacht experience, the program, landscape, facilities and service was found to have a significant influence on the users' stress recovery, and satisfaction through stress recovery had a significant effect on the intention to revisit and to share the SNS. In the verification of the moderating effect according to age, a generational difference in revisit intention between the MZ generation and other generations was confirmed. Through this study, it was suggested that various programs of yacht experience should be developed to induce users to revisit, and various marketing using SNS should be carried out.

Background: Self-gravity acupressure (SGA), which complements the limitations of conventional manual therapies, is expected to have a positive effect on mood, closely related to reduction in stress. Purpose: This study aims to evaluate changes in mood states by SGA and to discuss its effects on stress relief and immunity. Methods: For 118 subjects (21 males and 97 females) who experienced the SGA program for 75 minutes, their mood states were assessed before and after the SGA session on 5 scales (0-4 points) using K-POMS consisting a total of 65 items grouped in six factors. For calculating the total mood disturbance score (iTMDs), the scores of the items in the only positive mood factor 'vigor-comfort' were reversed to have iTMDS increase the degree of the positive correlation with negative mood states. Results: The iTMDS decreased by 11.50% from 1.09±0.54 before SGA to 0.63±0.40 after SGA (p<0.001). The average score of the only positive factor 'vigor-comfort' increased by 10.78%, from 1.93±1.17 before SGA to 2.38±1.31 after SGA (p<0.001). On the other hand, the factor 'fatigue-inertia' of the 5 negative factors decreased most significantly in its average score by 16.73%, from 1.19±1.24 before SGA to 0.40±0.58 after SGA (p<0.001). The remaining 4 negative factors (depressed state, anxiety-fear, anger-hostility, and uncertainty-helplessness) decreased by within the range of 7.75% to 11.33% (p<0.001). Conclusions: Changes in K-POMS scores observed in this study indicate that the SGA program improves significantly mood. Since a mood state is closely related to stress and immunity, SGA is expected to have effects on stress relief and immunity enhancement (p<0.001). Continued studies are suggested to further validate the present results and to enhance the clinical utility, which include physiological signal measurements and clinical pathological examinations to test the effetcs of SGA on stress management and immunity enhancement.

This study was to develop a simulation model of a compound planetary gear reducer for the final driving shaft using a gear analysis software (KISSsoft, Version 2017, KISSsoft AG, Switzerland). The aim of this study is to analyze transmission error and the tooth load distribution through micro-geometry using the simulation model. The tip and root relief were modified with Micro-geometry in the profile direction, and crowning was modified with Micro-geometry in the lead direction. The transmission error was analyzed using the PPTE (Peak to Peak Transmission Error) value, and the tooth load distribution was analyzed for the concentrated stress on the tooth surface. As a result of modifying tip and relief in the profile direction, the transmission error was reduced up to 40.7%. In the case of modifying crowning in the lead direction, the tooth load was more evenly distributed than before and decreased the stress on the tooth surface. After modifying the profile direction for the 1st and 2nd planetary gear train, the bending and contact safety factors were increased by 31.7% and 17%, and 18.3% and 12.5% respectively. Moreover, the bending and safety factors after modifying lead direction were increased by 59.5% and 32.7%, respectively for the 1st planetary gear train, and 59.6% and 43.6%, respectively for the 2nd planetary gear train. In future studies, the optimal design of a compound planetary gear reducer for the final driving shaft is needed considering both the transmission error and tooth load distribution.
