The main characteristics of a new cultivar 'Jinhyang', a cross of a collection of monokaryotic strains of the brown button mushroom, were examined. 'Jinhyang' was not significantly different from the control cultivar 'Dahyang' in mycelial culture and cultivation period. The cap of 'Jinhyang' was thicker and darker in color than that of 'Dahyang'. The hardness and individual weight of the fruiting body of 'Jinhyang' were slightly higher than those of 'Dahyang'; however, the differences were not significant. The yield of 'Jinhyang' was 14.1 kg/m², which was 8% higher than that of 'Dahyang'. Therefore, it is expected that it will be possible to supply this cultivar growers in the future.

Purpose: The purpose of this study was to identify factors associated with performance of nursing care for postoperative delirium of elderly patients among recovery room nurses. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 99 nurses from five urban recovery rooms. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with SPSS WIN 21.0. Results: The performance level of delirium nursing care was low because its mean score was 3.80 out of 5. Performance of nursing care was significantly positively correlated with the importance of nursing care and self-efficacy. Stepwise multiple regression analysis for performance of nursing care revealed that the most powerful predictor was the importance of nursing care. The importance of nursing care and self-efficacy explained 32.3% of the variance. Conclusion: The results indicate a need to enhance the performance of nursing care for postoperative delirium of elderly patients among recovery room nurses. The findings also suggest that consideration be given to strategies for improving the importance of nursing care and self-efficacy in developing programs to enhance the performance level of nursing care for elderly patients with postoperative delirium.

Purpose: This ethnography was performed to explore patterns and meanings of healthy life among aged women using senior centers. Methods: The informants were 21 individuals aged 65 years and older at 2 community-based senior centers. Data were collected from iterative fieldwork through in-depth interviews and participant observations and analyzed using text analysis and taxonomic methods developed by Spradley. Field notes were used with follow-up interviews and dialogue between authors to enhance interpretation. Results: Patterns of healthy life among aged women using senior centers were categorized by age groups within the context of the four cultural elements of taking care of the body, relationality, temporality, and spatiality: active and passive control, maintenance of interdependence and individuality, expansion and maintenance of the daily routine, unity of peer relations and sustenance of family relations, spending time productively and tediously, and complementary and alternative space of the family relations. Conclusion: The informants in this study demonstrated healthy life by maintaining and strengthening continuous relationships developed in the senior centers without being isolated from the family and society. Patterns of their healthy life differed across age groups within the socio-cultural context. Therefore, interventions should be tailored to address age groups and community needs.

In this work, an one-dimensional analysis on spontaneous combustion in a coal stockpile was conducted using a commercial software $gPROMS^{(R)}$ based on assumption suggested by Arioy and Akgun. According to them, it is assumed that there is temperature difference between the surface of coal particle and the gas surrounded around the particle, and it is also assumed that the velocity of the gas is constant and thus oxygen is fed to the stockpile with same velocity. The higher temperature zone is formed to the surface of the coal stockpile at the initial phase and it became deepen as time is taken. Finally it was found that the temperature difference between coal particle and the gas was calculated as $57^{\circ}C$ and spontaneous combustion have not been occurred during 6 months since coal was piled in the stock.

Purpose: This study was done to explore adaptation experience of living kidney donors after donation. Specific aims were to identify challenges donors face in the process of adaptation following surgery and how they interact with recipients and other people. Methods: Grounded theory methodology was utilized. Participants were 13 living kidney donors at six months or more after donation. Data were collected by in-depth interviews with individual participants. Data were analyzed using constants comparative method with theoretical saturation. Results: A core category emerged as 'keeping the fences of my family in spite of vulnerability'. The adaptation process after donation was manifested in four phases: exploration, balance, maintenance, and acclimatization. Phenomenon was perception of vulnerability. Strategies to manage the vulnerability were assessing changes of body awareness, tailoring regimen to one's own body condition, coping with health problems, keeping restoration of health, and ruminating on the meaning of one's kidney donation. Consequences were reestablishing family well-being, realizing the values of one's kidney donation, and living with uncertainty. Conclusion: Findings of the study indicate that there is a need for health professionals to understand the vulnerability of living kidney donors and help their family system maintain a healthy and productive life. The results of this study can be used to develop phase-specific, patient-centered, and tailored interventions for living kidney donors.

Purpose: Patients on hemodialysis need to manage the stress of having a life-threatening condition. The purpose of this study was to identify factors associated with stress among patients on hemodialysis. Methods: The research had a cross-sectional, descriptive design using a questionnaire. The participants were 91 adult patients on hemodialysis from four dialysis centers in a large Korean city. Data were analyzed with the SAS 9.2 program using descriptive statistics, t-tests, ANOVA, and multiple regression. Results: There were statistically significant differences in stress by age, dialysis period, and change in employment status. In hemodialysis patients, stress was significantly positive correlated with fatigue and depression, but negatively correlated with self-esteem. Stepwise multiple regression analysis for stress revealed that the most powerful predictor was depression. Depression and fatigue explained 32.5% of the variance. Conclusion: The results indicate a need to manage the stress of these patients. The findings also suggest that consideration be given to characteristics of age, dialysis period, and employment status in developing strategies to reduce depression and fatigue and developing programs to manage the stress of patients on hemodialysis.

Purpose: Influenza immunization among health personnel is of particular importance given their elevated risk of influenza infection, role in transmission and influence on patients' immunization status. The purpose of this study is to identify factors associated with the influenza vaccination intention among health personnel based on the theory of planned behavior. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 131 health personnel in five general hospitals in two cities in South Korea. The data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with the SPSS 26.0 program. Results: There were statistically significant differences in influenza vaccination intention according to the high-risk group in the family, occupation, length of employment, and influenza vaccination status within a year. The influenza vaccination intention of these health personnel showed significant positive correlations with attitude, subjective norms, and perceived behavioral control towards influenza vaccination. Multiple regression analysis for influenza vaccination intention revealed that the significant predictors were attitude, subjective norms, influenza vaccination within a year and physician in occupation. These factors explained 41.4% of the variance. Conclusion: The results suggest a need to strengthen attitude and subjective norms. The findings also suggest that their characteristics through influenza vaccination status within a year and occupation should be considered for tailored interventions related to the intention. Furthermore, it is necessary to develop programs strengthening attitude and subjective norms to enhance influenza vaccination intention among health personnel.
