  • Purpose: The purpose of this study was to examine the relationship of psychosocial wellbeing status and self leadership with job satisfaction of fire officers. The effects of these variables on job satisfaction were also examined. Methods: The study design was a descriptive, correlational design. For this study, data were collected from 189 fire officers in B metropolitan city, K and Y cities. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and multiple regression analysis with SPSS 21.0 program. Results: The results showed that job satisfaction had a significant correlation with psychosocial wellbeing status (r=-.38, p<.001) and self leadership (r=.26, p<.001). Psychosocial wellbeing status had a significant correlation with self leadership(r=-.47, p<.001). Multiple regression analysis for job satisfaction revealed that the most powerful predictor was psychosocial wellbeing status followed by self leadership. Pychosocial wellbeing status, self leadership, age, marital status and current job task career explained 25.0% of the variance in job satisfaction. Conclusion: Findings indicate that various factors are related to the job satisfaction of fire officers. Based on the results of this study, further development and application of programs to improve fire officers' job satisfaction are needed.

  • The effects of long-term fertilization on soil biological properties and microbial community structure in the plough layer in a rice paddy soil in southern Korea were investigated in relation to the continuous application of chemical fertilizers (NPK), straw based compost (Compost), combination these two (NPK + Compost) for last 40 years. No fertilization plot (Control) was installed for comparison. Though fertilization significantly improved rice productivity over control, the long-term fertilization of NPK and compost combination was more effective on increasing rice productivity and soil nutrient status than single application of compost or chemical fertilizer. All fertilization treatments had shown significant improvement in soil microbial properties, however, continuous compost fertilization markedly increased soil enzyme and microbial activities as compared to sole chemical fertilization. Results of microbial community structure, evaluated by EL-FAME (ester-linked fatty acid methyl esters) method, revealed big difference among Control, NPK, and Compost. However, both Compost and Compost+NPK treatments belonged to the same cluster after statistical analysis. The combined application of chemical fertilizer and organic amendments could be more rational strategy to improve soil nutrient status and promote soil microbial communities than the single chemical fertilizer or compost application.
