The objective of this study was to investigate the changes in flavor components of cheonggugjang prepared with hazelnut. Amino nitrogen content in cheonggukjang was significantly lower in the 30~40% hazelnut group compared to the control group. The volatile basic nitrogen of hazelnut added cheongkukjang showed a similar pattern to that of amino nitrogen. The number of B. subtilis was slightly increased in relation to the amount of hazelnut added, but there was no significant difference. The content of glucose increased proportionally with increasing hazelnut. Total amino acid content decreased with increasing hazelnut. The ratio of glutamic acid to total free amino acids increased with increasing hazelnut. Oleic acid content increased proportionally with increasing hazelnut, while linoleic acid content decreased. In conclusion, the addition of hazelnut may contribute to the quality diversification of cheonggukjang by changing the taste and flavor while maintaining the amino nitrogen content of cheonggukjang.

This research was conducted to elucidate the optimum conditions for the antibacterial activity of konjak jelly using the evolutionary operation-factorial design technique. In the first set of experiments, concentration of a coagulation agent, soaking liquid, and temperature of water were set to 0.4%, $0.6{\times}10^{-2}N$, and $65^{\circ}C$ as a central point, respectively. The highest antibacterial activity was acquired at E21, in which the number of bacteria was 1.25 log cfu/g. Because the code of changes in the main effect was (-), it could be decided that the central point of the first set was not the optimum point. Although antibacterial activity in the second set was improved, the values of the main effect were higher than that of changes in the mean effect. The central point of third set was concentration of coagulation agent 0.8%, concentration of soaking liquid $1.0{\times}10^{-2}N$, and temperature of water $65^{\circ}C$. It was found that the antibacterial activity of central point in the third set was highest among all the tested set. Further, all the necessary conditions were appropriate to reach the optimum condition. The antibacterial activity of the central point in third set was more than 1,000 times higher than that of E11, in first set.

Purpose: This study focuses on the relationship among burnout, job stress and self-efficacy of psychiatric nurses. This descriptive correlational research intend to offer a base on programs to reduce and prevent burnout that psychiatric nurses frequently occur. Methods: Two hundred and thirty seven psychiatric nurses were recruited from April to May, 2011. The instruments were the Burnout measurement instrument, Job stress measurement instrument, Self-efficacy measurement instrument. The data were analyzed by descriptive statistics, ANOVA, Pearson`s correlation coefficient, and Scheffe`s test using the SPSS/WIN program. Results: The analytic results reveal that job stress and self-efficacy have influence on burnout of psychiatric nurses. Conclusion: These analytic results in our research indicate that ``burnout``, ``job stress`` and ``self-efficacy`` have the significant positive correlations; The higher job stress has, the higher burnout becomes, whereas the lower self-efficacy becomes. The higher self-efficacy has, the lower burnout becomes. High job stress and low self-efficacy aggravate burnout. Therefore, an effective strategy to improve self-efficacy and decrease job stress requires to reduce burnout of psychiatric nurses.

Purpose: This study was to investigate the effects of communication styles and stress coping on college adaptation in nursing students. Methods: The data was collected by questionnaires from 180 nursing students in a university in Gyeongsan, Korea. The data were analyzed with the SPSS/Win 23.0 program, using descriptive statistics, independent t-test, and multiple logistic regression. Results: A positive correlation was found for college adaptation with a functional communication pattern such as leveling stance (r=.36, p<.001) and stress coping (r=.39, p<.001). With more using of functional communication and with higher level of active coping of stress coping, nursing students appeared to more successfully adaptation to college life. It was also found that an explanatory power for college adaptation of these factors was 29.8%(F=20.01, p<.001). Conclusion: The study results indicate that it is necessary to develop various programs that can improve effective communication and active coping of stress coping of nursing students in order to enhance the adaptation process to college life.
분노표현과 외현화 문제행동의 관계에서 사회적 민감성 기질과 인내력 기질의 조절효과

본 연구는 청소년의 분노표현과 외현화 문제행동의 관계에서 사회적 민감성 기질과 인내력 기질의 조절효과를 확인하는 데 목적이 있다. 이를 위해 2015년 12월 7일부터 18일까지 12일간 부산 소재 고등학교 3개교의 1·2학년생을 대상으로 수집된 547명의 자료를 사용하였다. SPSS 21.0 프로그램으로 신뢰도 분석과 기술통계, 상관분석을 시행하였으며, 다중공선성 문제를 해결하기 위해 독립변수와 조절변수의 값을 평균 중심화한 후, 위계적 회귀분석으로 조절 효과 분석을 하고 그래프로 나타냈다. 결과는 다음과 같다. 첫째, 분노조절, 분노억제와 외현화 문제행동의 관계에서 사회적 민감성 기질의 조절 효과가 검증되었다. 둘째, 분노표출, 분노억제와 외현화 문제행동의 관계에서 인내력 기질의 조절 효과가 검증되었다. 이는 사회적 민감성 기질과 인내력 기질에 따라 분노표현과 외현화 문제행동의 양상이 달라질 수 있음을 시사하므로 두 기질의 계발을 통하여 청소년의 대인관계 향상뿐 아니라 문제 상황에서 발생할 수 있는 충동성을 감소시켜 청소년 문제행동의 강도와 발생률을 낮출 수 있을 것으로 기대할 수 있다. The purpose of this study is to verify the moderating effect of both Reward-dependence temperament and persistence temperament in terms of adolescent anger expression and external behavior problem. This study used 547 students data collected by 1st and 2nd grad high school students from Busan 3 different schools. Reliability analysis, descriptive statistics and a correlation analysis are implemented by SPSS 21.0 program and variable moderating effect were analyzed and graped through hierarchical analysis to solve the multicollinearity after mean-centering of the independent variable and moderator, The result is as follows. First, the moderating effect of reward-dependence temperament was verified through the anger control, anger in and external behavior problem. Second, the moderating effect of persistent temperament was verified through Anger-out, anger-in and the external behavior problem. This study implies that the aspect of anger expression and external behavior problem can be different according to the reward-dependence temperament and persistence temperament, and so we can expect that the strength and incidence rate can be reduced through the development of two temperaments by improving adolescent interpersonal relation and reducing impulsiveness that can be happened in problematic situation.
