This paper examines the effect of patriarchal family on female delinquency from the perspective of power-control theory, employing various measures for testing the theory. Extending power-control theory, this study measures the concept of 'patriarchal anomie' which implies the situation where girls' progressive views on gender role are in conflict with parents' patriarchal values. In addition, the mediating effects of the delinquent associations and the parental supervision are investigated. The results generally show that a series of variables on patriarchal family have statistically significant effects on female delinquency. Specifically, the variables for patriarchal family measured in terms of parents' occupation and education level significantly decrease female delinquency. This study also finds that girls with patriarchal attitudes are less likely to be delinquent. However, girls with progressive views on gender role living with patriarchal parents are more likely to be delinquent. This study finds that the deterrent effects of patriarchal family as well as the facilitating effect of patriarchal anomie are mediated by delinquent association. And it reports that the variable of patriarchal family measured by parents' occupation decreases female delinquency through parental supervision.

The objective of this study is to compare and assess the effectiveness of real-time polymerase chain reaction (RT-PCR), loop-mediated isothermal amplification (LAMP), and the selective agar plate method for the detection of Salmonella spp. and Listeria monocytogenes in ready-to-eat (RTE) foods. In RTE foods, the detection performance of the three methods (RT-PCR [SureTect^TM kit and PowerChek^TM kit], LAMP [3M MDS], selective agar) were similar at 0-10, 10-50, 50-100, and 100- CFU/mL of Salmonella spp. and L. monocytogenes. We found that with RT-PCR, the Ct value of salad was significantly higher (p<0.05) than other RTE foods, indicating that fiber plays a critical role as an obstacle to the rapid detection of Salmonella spp. However, the Ct value displayed a mixed pattern according to the inoculation level of L. monocytogenes. The use of rapid detection kits and machines mostly depends on the user's choice, with accuracy, ease of use, and economy being the primary considerations. As an RT-PCR kit, SureTect^TM and PowerChek^TM showed high accuracy in detecting Salmonella spp. and L. monocytogenes in RTE foods, showing that they can replace the existing RT-PCR kits available. Additionally, LAMP also showed excellent detection performance, suggesting that it has the potential to be used as a food safety management tool.

The purpose of this descriptive survey study was to explore the effects of emotional labor on professional quality of life of emergency department nurses and to elucidate any mediating effects of emotional dissonance between emotional labor and professional quality of life. A total of 227 nurses, including general, charge, and head nurses, who have worked in an emergency department at university hospitals, general hospitals, and junior general hospitals located in Gyeongnam, Daegu and Gyeongbuk areas over a period of 6 months. Data were collected between December 12 and December 29 of 2015. We analyzed the data with descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and three-step mediated regression analysis using SPSS/WIN 21.0 program. The average scores of emotional labor, compassion satisfaction, compassion fatigue, burnout, and emotional dissonance were 4.50 out of 7.00, 31.62 out of 50.00, 29.48 out of 50.00, 29.27 out of 50.00, and 5.02 out of 7.00, respectively. Emotional labor had significant effects on compassion fatigue and burnout, showing explanatory power of 12% and 29%, respectively. Emotional dissonance had partial mediating effects in the relationship between emotional labor and compassion fatigue and complete mediating effects in the relationship between emotional labor and burnout. In summary, to improve the professional quality of life of nurses, it is necessary to develop effective strategies to minimize their emotional labor and emotional dissonance.

In this study, the optimization of the biodiesel production process from waste oil using microwave with response surface methodology (RSM) was conducted. The microwave irradiation time and power in addition to the alcohol/oil mole ratio were chosen as process parameters. Also the fatty acid methyl ester (FAME) content (over 96.5%) and kinematic viscosity (1.9~5.5 cSt) were selected as response values. From basic experiments, the range of quantitative factors were set as following; 4~6 min, 400~600 W, and 7~9 for the microwave irradiation time and power, and alcohol/oil molar ratio, respectively. The optimum conditions for the methanolysis were 5.0~5.1 min, 481.3~525.5 W, 7.9~8.4, and 2.0 or 3.0 mg KOH/g for the microwave irradiation time and power, methanol/oil molar ratio, and each acid value, respectively. The FAME content and kinematic viscosity were predicted as 97.49~96.34% and 4.01~4.12 cSt, respectively, under the condition above. Under the optimum experimental conditions, the results showed that the FAME content and kinematic viscosity of 97.82~96.42% and 4.07~4.16 cSt, respectively were measured and the mean error rates were 0.22% and 0.98%, respectively.

This study was designed to empirically analyze the effect of control activities(physical, managerial and technical securities) of information protection on organizational effectiveness and the mediating effects of information application. The result was summarized as follows. First, the effect of control activities(physical, technical and managerial securities) of information protection on organizational effectiveness showed that the physical, technical and managerial security factors have a significant positive effect on the organizational effectiveness(p < .01). Second, the effect of control activities(physical, technical and managerial securities) of information protection on information application showed that the technical and managerial security factors have a significant positive effect on the information application(p < .01). Third, the explanatory power of models, which additionally put the information protection control activities(physical, technical and managerial securities) and the interaction variables of information application to verify how the information protection control activities( physical, technical and managerial security controls) affecting the organizational effectiveness are mediated by the information application, was 50.6%~4.1% additional increase. And the interaction factor(${\beta}$ = .148, p < .01) of physical security and information application, and interaction factor(${\beta}$ = .196, p < .01) of physical security and information application among additionally-put interaction variables, were statistically significant(p < .01), indicating the information application has mediated the relationship between physical security and managerial security factors of control activities, and organizational effectiveness. As for results stated above, it was proven that physical, technical and managerial factors as internal control activities for information protection are main mechanisms affecting the organizational effectiveness very significantly by information application. In information protection control activities, the more all physical, technical and managerial security factors were efficiently well performed, the higher information application, and the more information application was efficiently controlled and mediated, which it was proven that all these three factors are variables for useful information application. It suggested that they have acted as promotion mechanisms showing a very significant result on the internal customer satisfaction of employees, the efficiency of information management and the reduction of risk in the organizational effectiveness for information protection by the mediating or difficulty of proved information application.

Purpose: This study aimed to investigate the influence of post-traumatic stress on professional quality of life as mediated by cognitive emotion regulation among nurses working in small and medium hospitals who have experienced violence and to develop and test a structural equation model of that professional quality of life. Methods: Participants were 215 nurses who had experienced violence working in medium and small hospitals. They were surveyed using a structured questionnaire. Results: The final model was shown to have good fit with χ² (2.83), GFI (.90), TLI (.90), and CIF (.90). Therefore, the model was selected as the final model, supporting 7 of the 11 hypotheses. Post-traumatic stress, adaptive emotional regulation, and maladaptive emotional regulation had significant impacts on empathy satisfaction (professional quality of life subscale) and empathy fatigue (subscale of professional life quality) among nurses who had experienced violence, and the explanatory power of these variables was 28.7% and 38.6%, respectively. Conclusion: In the development of nursing intervention programs to improve the professional quality of life of nurses who have experienced violence, factors such as post-traumatic stress and cognitive emotion regulation (adaptive and maladaptive) should be considered as they were identified in this study as influencing the professional quality of life of such nurses in medium and small hospitals.

The present study explored types of Twitter-mediated communication and emotional responses of Twitter users toward celebrities. Three perspectives of para-social interactions, information hub, and fandom were proposed as communication types on Twitter. Celebrities were classified by entertainer, politician, specialist, and blogger. Communication patterns according to each category of celebrities were analyzed. The patterns of emotional responses, which represents the use of emoticons and emotional expressions were also analyzed. The results show that the type of para-social interactions was frequently accepted for the interactions with politicians and specialists, while fandom style was salient for the entertainers. For the power bloggers, the users tend to adopt the type of information hub interaction. The use of emotions and emotional expressions were most frequent in case of fandom style communication and the messages to the entertainers. Implications were further discussed.

Drawn upon the analysis of Seoul community media, this study make six points. The generation of community is not essentially determined but has singularity and differences. Historical context, social conditionality, cultural orientation, and the subjects' will and anticipation bring out certain forms of community. Various power relations and desires are engaged in the formation of community. The process of the construction of community is necessarily and simultaneously mediated with collective acts of communication and sharing. Community is not so much cultivated within society as articulated with precariousness, negativity and limit. Community is able to create its own cultural sensibility and language to express it. Thereby community is a dynamics between articulation and disarticulation, convergency and divergency, similitude and difference living in our actual society.
