Effects of Anger and Entrapment on Psychological Health of High School Boys: Focused on the Mediating Effects of Social Support

PURPOSE: The aim of this study was to identify the status of psychological health among boys in high school and to examine the mediating effects of social support on the relationship between anger and entrapment on psychological health. METHODS: The participants in this study were 193 high school boys from Jeju. Measurements included state-trait anger expression inventory, entrapment scale, student social support scale, and questionnaires to assess mental and physical health. Data were analyzed using independent t-test, one-way ANOVA, Scheffé test, Pearson correlation coefficient, simple and multiple regression techniques with the SPSS 21.0. Mediation analysis was performed with the Baron and Kenny's method, and Sobel test. RESULTS: Mean scores for anger experience, entrapment, social support, and psychological health were 29.81±7.34, 34.09±16.33, 45.75±7.02, 22.51±9.91, respectively. There was a significant correlation between anger experience and psychological health. Entrapment was significantly correlated with psychological health. Social support showed partial mediating effects in the relationship between anger experience and psychological health (Sobel test: Z=54.18. p<.001). Social support showed partial mediating effects in the relationship between entrapment and psychological health (Sobel test: Z=2.24. p=.025). CONCLUSION: The results indicate a need to develop social support programs for boys in high school.

Validity and Reliability of the Peer Group Caring Interaction Scale-Korean Version

PURPOSE: This paper was conducted to validate the Korean version of the Peer Group Caring Interaction Scale (PGCIS-K) that measures caring behaviors as experienced by nursing students. METHODS: Translation of the PGCIS-K was validated through forward-backward translation methods. Survey data were collected from 218 nursing students in a nursing school. Construct validity and criterion-related validity were evaluated. Internal consistency and the Guttman split-half coefficient were calculated to assess reliability. RESULTS: The PGIS-K showed reliability except for 4 items (Cronbach's α=.91, Guttman split-half coefficient=.85), which were low (<.30) or negatively correlated with the total scale. A 12-item reduced form of the PGCIS-K was developed by item-analysis and construct validity evidence. Factor loading for the 12 items on 2 factors ranged from .47~.82, which explained 58.4% of the total variance. Two factors were named 'modeling and assistance (Cronbach's α=.87)' and 'communication and sharing (Cronbach's α=.82)'. Convergent validity, discriminant validity, and criterion validity were supported according to the correlation coefficients of the 2 factors with other measure. CONCLUSION: The findings suggest preliminary evidence that the 12-item PGCIS-K can be used to measure nursing students' peer group caring interactions in Korea. Additional studies are recommended to continue the psychometric evaluation of this scale. Also, it can be extended to measure graduate nursing students or staff nurses' peer group caring interaction.

Cardiopulmonary Resuscitation Learning Experience, Knowledge, and Performance in Newly Graduated Nurses / 기본간호학회지

PURPOSE: The purpose of this study was to evaluate the learning experience, knowledge, and performance of cardiopulmonary resuscitation (CPR) in newly graduated nurses, and to identify differences related to learning experience. METHODS: The participants were 114 new nurses in the hospital. They were asked to complete a questionnaire, which included CPR learning experience. They were evaluated by a written test and a skill test using a manikin and check list. RESULTS: All participants attended CPR lectures and underwent practice while in university. Only 12.28% of participants were taught by a certified Basic Life Support (BLS) instructor. The mean scores of the written and skill tests were 79.82+/-12.69 and 64.41+/-11.71, respectively. The nurses lacked CPR knowledge related to checking breathing, the frequency of 30 chest compressions, compression rate, and automated external defibrillator use. They also lacked skill in performing CPR related to checking breathing and pulse and giving 2 breaths. CPR performance differed according to learning time (p=.047) and BLS educator (p=.029). CONCLUSION: The findings of this study reveal that CPR performance by newly graduated nurses is poor and suggest that CPR education by trained instructors, practice-based education, and reeducation programs must be provided to newly graduated nurses in the hospital.

The Characteristics of Cultural Conditions for the Mycelial Growth of Macrolepiota procera

Macrolepiota procera, one of edible mushrooms belongs to Agaricaceae of Basidiomycota, has a good taste and good medicinal value. As a preliminary study for the development of artificial cultivation method of edible mushroom, cultural characteristics of M. procera was investigated on various culture media under different environmental conditions. Mycelial growth was compared on culture media composed of various carbon and nitrogen sources, and C/N ratios. The optimal conditions for the mycelial growth were 30degrees C and pH 7. M. procera showed the rapid mycelial growth in the PDA media. The optimal carbon and nitrogen sources were maltose and glycine, respectively. The optimum C/N ratio was about 10 : 1 in case that 1% glucose was supplemented to the basal media as carbon source.

Culture Conditions Affecting the Optimal Mycelial Growth of Cystoderma amianthinum

Cystoderma amianthinum, one of edible fungi belongs to Agaricaceae of Basidiomycota, has a good taste and flavor. This study was carried out to obtain the basic informations for the optimum mycelial growth of C. amianthinum. The optimal conditions for the mycelial growth were 25degrees C and pH 5 in potato dextrose agar (PDA). C. amianthinum showed the favorable growth in the PDA and yeast malt extract agar (YMA). The favorable carbon and nitrogen sources promoting mycelial growth were fructose and histidine, respectively. The optimum C/N ratio was about 30 : 1 in case that 1% glucose was supplemented to the basal medium as a carbon source.
