This paper presents energy self-sufficiency simulated in municipal wastewater treatment plants (WWTPs) by adopting solar energy production systems that vary with installation conditions. Relative to the national average energy consumption in WWTPs, the employment of 100 kW photovoltaics (PVs) was simulated to achieve 2.75% of energy self-sufficiency. The simulated results suggested that the installation of PVs toward South or South west would produce the highest energy self-sufficiency in WWTPs. When super-hydrophilic coating was employed in the conventional PVs, 5% of additional solar energy production was achievable as compared to uncoated conventional PVs. When 100 kW of PVs were installed in a future test-bed site, Kihyeung Respida located in Yougin, Sourth Korea, the energy self-sufficiency by solar energy was simulated to be 1.77% (2010). The simulated energy self-sufficiency by azimuth(direction) will be useful reference for practitioners in designing the solar PV systems in the WWTPs.

Purpose: The purpose of the study was to investigate psychological factors such as eating psychopathology, depression, and obsessive-compulsion that might influence self-harm behavior in patients with eating disorders. Methods: Patients with eating disorders (n=135) who visited "M" clinic for eating disorders participated in the study. Data were collected from March to August 2007 using the Eating Disorder Inventory-2, Beck Depression Inventory, Maudsley Obsessional-Compulsive Inventory, and Self-Harm Inventory (SHI). Results: The participants scored high on self-harm as well as on depression and obsessive-compulsion. On the SHI, a high frequency of self harm behavior such as 'torturing self with self-defeating thoughts', 'abused alcohol', 'hit self', and 'suicide attempt' were found for the participants. There were significant correlations between most eating psychopathology variables, depression, obsessive-compulsion, and self-harm behavior. 'Interoceptive awareness' (eating psychopathology), depression, and 'checking' (obsessive-compulsion) were significant predictors of self-harm behavior. Conclusion: Future interventions for patients with eating disorders should focus on assessing the possibility of self-harm and suicidal attempts, especially in those patients with high levels of eating psychopathology, depression, or obsessive-compulsion. Early intervention for depression and obsessive-compulsion could contribute to preventing self-harm and suicide in patients with eating disorders.

This study investigates the effects of the fulfillment of self-motivation including self-development, self-therapy, and self-presentation on the outcomes such as subjective quality of life, omnivorous cultural engagement, and visitor loyalty via visitor satisfaction in art museums. The analyses on 285 valid survey responses demonstrated that fulfillment of self-development and self-therapy needs have significant positive influence on visitor satisfaction. The effect of fulfilling self-presentation need on visitor satisfaction was found to be moderated by attitude toward SNS posting, while the age factor, based on generations, did not show a significant moderation effect. It was also found that visitor satisfaction positively influences visitor loyalty, including intentions of revisit and recommendation. Increased satisfaction also enhances subjective QOL and omnivorous cultural engagement among art museum visitors, implying promising collaboration among cultural arts institutions. The findings have both theoretical and practical implications for enhancing visitor experiences and promoting diverse cultural engagement. Limitations and future research directions are also discussed.

This is a group pretest-posttest design study that aim to evaluate the effect of self-reflection promotion program of nursing students. The subjects of this study were 42 first-year nursing students. The data was collected from October 5 to November 2, 2020. A questionnaire was used to measure self-reflection and self-efficacy. The self-reflection promotion program was operated for a total of 8 hours in 4 sessions over 4 weeks. Online lectures were conducted using books, movies, and art recommended by expert. The subjects could take lectures using their smartphones, laptops, desktops, and tablet PC. As a result of the study, self-reflection was significantly improved after intervention than before intervention (t=-2.594, p=.013). In the sub-items, self-exploration and self-understanding were statistically significantly improved (t=-2.527, p=.015; t=-2.471, p=.018). However, other-exploration and other-understanding were not statistically significant (t=-1.226, p=.227; t=-.758, p=.453). The self-efficacy of the subjects was not statistically significant (t=-.170, p=.866). In future research, it will be necessary to develop and verify specific teaching and learning methods utilizing various contents that can improve self-reflection for nursing students.
