Purpose: The purpose of the study was to examine the relationships between cognitive coping, hope, depression, and life satisfaction of hemodialysis patients based on the stress-coping model. Methods: For this cross-sectional survey, 142 participants were recruited from 10 local clinics in Seoul and Daegu during 2012-2013. The data collection instruments included the Cognitive Emotion Regulation Questionnaire, the Herth Hope Index, the Hospital Anxiety and Depression Scale, and the Satisfaction with Life Scale. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation analysis, and stepwise multiple regression. Results: The cognitive coping scores were significantly related to hope, depression, and life satisfaction. The coping strategies explained 80%, 37%, and 38% of the variances in hope, depression, and life satisfaction, respectively. The most powerful coping strategy was positive refocusing, explaining 73% in hope, 25% in depression, and 25% in life satisfaction. Conclusion: The results of the study indicate that cognitive coping plays an essential role for psychological adaptation of hemodialysis patients. Thus, interventions integrating positive refocusing would help instilling hope of hemodialysis patients in Korea.

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: Focusing manner is very powerful mind-body self-help and self-awareness competence. So focusing manner may affect nurses' emotional labor and nursing performance, but few are known about it to date. The purpose of this study was to identify the degree of focusing manner, emotional labor, nursing performance of clinical nurses, and the factors that affect nursing performance. Methods: In order to collect data, structured questionnaires were administered to 212 nurses who worked at 2 university hospitals located in D city. Data were analyzed by t-test, ANOVA, correlation and multiple regression using SPSS/WIN 20.0. Results: Nursing performance had positive relationship with focusing manner (r=.45, p<.001), and negative relationship with emotional labor (r=-.25, p<.001). And the most prediction factor influencing nursing performance was focusing manner (${\beta}=.41$, p<.001) and the other factors were age (${\beta}=.30$, p=.002), and emotional labor (${\beta}=.14$, p=.012). The total variance was 37.1% by those predictors (F=25.87, p<.001). Conclusion: Based on the results of this study, it is necessary to develop and educational program on focusing manner-oriented psychotherapy in order to improve the nursing performance. Also, the management system for controlling emotional labor needs to be set up for nurses in clinical settings.

China is a land of guanxi, everything is connected with guanxi. China has a business culture based on guanxi connections underpinned by strong Confucian ethics. However, there are some reasons why it is difficult for western companies to run businesses in China. Firstly, foreign firms lack the understanding and experiences necessary for doing business in China. They don't know the absence of alternatives is one of reasons that guanxi is so powerful in Chinese society. Secondly, there are many misconceptions about guanxi. It is easier for many foreign scholars or businessmen to equate guanxi with corruption due to the ambiguity of guanxi. Thus, if a foreign enterprise possesses guanxi, it can be a source of competitive advantage for doing business due to lack of law systems for anti-corruption activities in China. Furthermore, it is gaining increasing importance not only in Business to Government(B2G) but also in Business to Consumers(B2C) relationships. Therefore,managers should pay great attention to the proper use of guanxi instead of being involved in corrupt behaviours because now the governments hold a strong attitude against corruption. In particular, establishment of working guanxi through red envelops(basically giving money) or illegal gifts can cause a great problem for both parties, which were naturally accepted among most government officials and businessmen until recently.

As the applications within Internet becoming more extensive, the security issues of those applications are appearing to be the most important concern. We have to be sure if all elements of the system are robust and perform well. Even if some small part of the system is vulnerable, it might cause the total system crash-down. Therefore, every part of the system should be thoroughly designed and mutually coordinated in order to support overall security of the system. In this paper, we propose new technique which uses the fingerprint features in order to generate one time passwords(OTPs). Fingerprint is considered to be one of the powerful personal authentication factors and it can be used for generating variable passwords for one time use. Also we performed a simulation for proposed password generation method.

Although plants have evolved to possess various defense mechanisms from local biotic and abiotic stressors, most of yield loss is caused by theses stressors. Recent studies have revealed that several different stress responsive reactions are inter-networking. Therefore, the identification and dissection of stress responsive genes is an essential and first step towards understanding of the global defense mechanism in response to various stressors. For this purpose, we applied cDNA microarray analysis, because it has powerful ability to monitor the global gene expression in a specific situation. To date, more than 10,000 non-redundant genes were identified from seven different cDNA libraries and deposited in our EST database (http://plant.pdrs.re.kr/ks200201/pepper.html). For this study, we have built 5K cDNA microarray containing 4,685 unigene clones from three different cDNA libraries. Monitoring of gene expression profiles of hot pepper interactions with biotic stress, abiotic stresses and chemical treatments will be presented. Although this work shows expression profiling at the sub-genomic level, this could be a good starting point to understand the complexity of global defense mechanism in hot pepper.

This study was carried out to investigate the effect of Pine needle extract on lipid oxidation and free radical reaction in iron sources reacted with active oxygen species. The results were summarized as follow; The pine needle extracts didn`t show a distinct effect on reduction of lipid oxidation if the iron ion didn`t exist in oil emulsion. The pine needle extracts played role as a strong chelating agents to bind iron ion if Ferrous iron(Fe\ulcorner) exist in oil emulsion. Ferric iron(Fe) was lower effect than Ferrous iron(Fe) on free radical reaction in oil emulsion. And also, the Fe\ulcorner reacted with pine needle extract did not show distinct effect on free radical reaction, compared to Fe\ulcorner reacted with pine needle extract. And also, Pine needle extracts reacted with H\ulcornerO\ulcorner were tended to show a low oxygen scavenging ability in case of H\ulcornerO\ulcorner only was existed, compared to those of H\ulcornerO\ulcorner + Fe\ulcorner complex. Pine needle extracts were the most powerful Fe\ulcorner binding agents, compared to other strong synthetic antioxidants such as EDTA and DTPA.

This study examined the relationship between maternal attitudes toward children's expressiveness, children's emotional intelligence and problem behaviors. The question as to whether emotional intelligence mediated the relationship between maternal attitudes and problem behaviors was also explored. A sample of 307 preschool children were used as subjects. Mothers rated their levels of acceptance toward their children's emotions, while teachers reported on the children's emotional abilities and behavioral problems. The data were analyzed by means of regression analyses. Our results indicated that mothers' controlling attitudes were associated with low levels of worry-anxiety. Additionally, it was found that children with high emotional intelligence showed low levels of worry-anxiety, hostility-aggression, and hyperactivity-inattention. While multiple factors of emotional intelligence had differential impacts, the self-control factor was the most powerful predictor for all the problem behaviors. It was further found that a mother's receptive attitude was related to higher levels of self-awareness in children. Instead of the significant mediating effect of emotional intelligence, it was revealed that emotional intelligence had greater effects upon problem behaviors than maternal attitudes toward children's expressiveness.

Purpose: Patients with chronic hepatitis B need lifelong health care because of progressive liver damage. The purpose of this study was to identify factors associated with self-management compliance among patients with chronic hepatitis B. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 118 patients with chronic hepatitis B from outpatient department in a tertiary hospital. Their ages ranged from 20 to 64. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with PASW statistics 19.0 program. Results: There were statistically significant differences in self management compliance by gender, age, job, alcohol consumption, and smoking. A positive correlation existed between self-management compliance, awareness of the importance of management, and self efficacy. Stepwise multiple regression analysis for self-management compliance revealed that the most powerful predictor was self efficacy. Self efficacy, age, and alcohol consumption explained 37.5% of the variance. Conclusion: The results indicate a need to promote self-management compliance with these participants. The findings also suggest that consideration be given to characteristics of age and alcohol consumption in developing strategies for enhancing self efficacy and developing programs to promote self-management for patients with chronic hepatitis B.
