Objective : The purpose of this study was to examine the level of the cognitive function, and to identify the influencing factors on cognitive function in women cancer patients receiving chemotherapy. This study attempted to provide basic data useful to development of nursing intervention and improve the quality of life in women cancer patients. Methods : As a cross-sectional descriptive study, women with receiving chemotherapy above one cycle were recruited. One hundred and twenty-five women cancer patients who met the study criteria agreed to participate in the study. The questionnaire set consisted of cognitive function, quality of life, depression, anxiety and information on demographic and clinical characteristics. Results : There was no statistically significant difference in clinical characteristics according to the cognitive function. The cognitive function was higher the more low age (F=9.937, p<.001), and the more high education level (F=12.332, p<.001). Multiple regression analysis showed the predictors were significantly related to cognitive function. age, education, and the number of chemotherapy explained 31.8% of the cognitive function. Conclusions : This result of this study provides basic information about factors influencing cognitive function, although study findings are insufficient in explaining related variables among women cancer patients. Even though women cancer patients were receiving chemotherapy, this study showed that the level of cognitive function was high. In order to receive better results and findings the period decreasing cognitive function, further studies are need to measure cognitive function according to the passage of time during or after chemotherapy.

In this study, the optimal location of the MR fluid segments in a partially treated laminated composite sandwich plate has been identified to maximize the natural frequencies and the loss factors. The finite element formulation is used to derive the governing differential equations of motion for a partially treated laminated composite sandwich plate embedded with MR fluid and rubber material as the core layer and laminated composite plate as the face layers. An optimization problem is formulated and solved by combining finite element analysis (FEA) and genetic algorithm (GA) to obtain the optimal locations to yield maximum natural frequency and loss factor corresponding to first five modes of flexural vibration of the sandwich plate with various combinations of weighting factors under various boundary conditions. The proposed methodology is validated by comparing the natural frequencies evaluated at optimal locations of MR fluid pockets identified through GA coupled with FEA and the experimental measurements. The converged results suggest that the optimal location of MR fluid pockets is strongly influenced not only by the boundary conditions and modes of vibrations but also by the objectives of maximization of natural frequency and loss factors either individually or combined. The optimal layout could be useful to apply the MR fluid pockets at critical components of large structure to realize more efficient and compact vibration control mechanism with variable damping.

This study was designed to investigate the stability of a lipase fused with a cellulose­binding domain (CBD) to cellulase. The fusion protein was derived from a gene cluster of a CBD fragment of a cellulase gene in Trichoderma hazianum and a lipase gene in Bacillus stearother­mophilus L1. Due to the CBD, this lipase can be immobilized to a cellulose material. Factors affecting the lipase stability were divided into the reaction-independent factors (RIF), and the re­action-dependent factors (RDF). RIF includes the reaction conditions such as pH and tempera­ture, whereas substrate limitation and product inhibition are examples of RDF. As pH 10 and $50^{\circ}C$ were found to be optimum reaction conditions for oil hydrolysis by this lipase, the stability of the free and the immobilized lipase was studied under these conditions. Avicel (microcrystal­line cellulose) was used as a support for lipase immobilization. The effects of both RIF and RDF on the enzyme activity were less for the immobilized lipase than for the free lipase. Due to the irreversible binding of CBD to Avicel and the high stability of the immobilized lipase, the enzyme activity after five times of use was over $70\%$ of the initial activity.

This study compares the benefits for online clothing purchases between Korean and U.S. consumers. A total of 464 usable questionnaires were obtained from respondents who resided in Korea (n=253) and the United States (n=21l). Data were analyzed by descriptive statistics, factor analysis, and MANOVA. For online clothing purchases, the benefit consisted of five factors: product attribute, transaction services, security, country of origin, and brand symbolism. Results showed that the main effect of nationality and gender on the benefit factors were significant; there was an effect of nationality on product attributes, transaction services, and country of origin. Compared with Korean consumer, U.S. consumers were more likely to consider the benefits of product attributes, transaction services, and country of origin for clothing in online purchases. In addition, there was a gender difference in benefit factors of product attributes, transaction services, country of origin, and brand symbolism. Females were more likely than males to consider the benefits for clothing in online purchases. An interaction effect of nationality and gender was not significant in online purchases for clothing. The managerial implications are discussed for global fashion marketing across the countries.

The main objectives of this study were to (1) examine and compare the importance of store attributes, store commitment, store attitude, and revisit intention concerning Korean mass cosmetic brand stores between female teenage consumers and those in 20's, and (2) investigate and compare the two groups in terms of the influences of five store commitment factors on store attitude and revisit intention. On-line surveys were conducted by the marketing research company, and a total of 354 questionnaires were used in the final analysis. The results showed several significant differences between the female consumer groups in 10's and 20's. The teenage respondents placed greater importance on all store attributes except price and sales, and showed higher commitment in terms of affective commitment, and normative commitment factors than the respondents in 20's. For the teenage respondents, all four commitment factors except the normative commitment significantly influenced their store attitude and revisit intention, while the affective commitment factor did not have significant influence on either store attitude and revisit intention for the group in 20's. Normative commitment factor also did not have significant influence on revisit intention of the group in 20's. For both age groups, the negative affects of the forced commitment on store attitude and revisit intention were found.

This study investigated factors that affect stress recognition, depression, suicidal thoughts and health-related quality of life for diabetics over 50 years of age. Five hundred one diabetics were surveyed who participated in the 4th Korea National Health and Nutrition Examination Survey 2009. The data were analyzed with multiple regression analysis and Structural Equation Model to determine the factors. The results are as follows. Men, older and lower income groups, those not involved in economic activities, smokers, and drinkers showed a lower quality of life (p<0.001). There was no correlation with moderate-intensity exercise. Stress recognition (t=-4.229, p<0.001), depression (t=-2.156, p<0.05), and suicidal thoughts (t=-3.274, p<0.001) had significant effects on the quality of life (p <0.001, $R^2=0.25$). The most important of these factors is stress. Being diagnosed as a diabetic changes the lives of patients, who come under stress from controlling their blood sugar level. Societal support should be developed to help patients cope with the challenges of diabetes.

Purpose: The public sectors including government and public organizations have put an efforts to improve the quality of people's lives by providing enhanced services. The purpose of this paper is to investigate the factors that affect job attitude, job satisfaction, and job performance in the public sector, that are rarely examined by previous studies. Research Design, data, and methodology: The following research questions have been proposed: i) how do payroll system, personnel management system, cooperative working environment, and self-efficacy affect job attitude?; and ii) how does job attitude affect job satisfaction and performance? This paper used a survey through an online platform and collected data randomly from five classified public institutions. This study applied regression analysis and ANOVA. Results: This study found that cooperative working environment and self-efficacy had significant impacts on job attitude, while payroll system and personnel management system did not affect job attitude. Overall job attitude affected both job satisfaction and performance. Conclusions: The results provide policy implications to the public sector which factors should be considered to improve job attitude, job satisfaction, and job performance. The results also provide managerial implications how such efforts ultimately improve service quality to the citizens.

This study empirically analyzes how the career orientation factors of startup entrepreneurs affect entrepreneurial satisfaction as well as business sustainability. We propose directions for startup sustainability and development. Based on previous research, we defined the career orientation of entrepreneurs through the five orientation factors of security, autonomy, technical competence, managerial competence, and entrepreneurial creativity. We constructed a research model to determine whether these factors have a causal relationship with entrepreneurial satisfaction or business sustainability through the medium of organizational entrepreneurship. We surveyed startups in Korea using a questionnaire and collected and analyzed a total of 282 points of survey data. The analysis results demonstrated that the entrepreneurial creativity and managerial competence of the members of a startup can play an important role within entrepreneurial satisfaction and business sustainability. Both autonomy and technical competence exhibited no effect on entrepreneurial satisfaction and business sustainability through the medium of entrepreneurship, while security showed a negative effect. In order to improve entrepreneurial satisfaction and achieve business sustainability, we confirmed that it was more important for startups to consider the creativity and business management competences of entrepreneurs rather than pursue business security or have a technology-oriented attitude.

Purpose: To examine geographical imbalances by analyzing new graduate nurses' migration patterns among regions where they grew up, attended nursing school, and had their first employment and to identify factors related to working in non-metropolitan areas. Methods: The sample consisted of 507 new graduates working in hospitals as full-time registered nurses in South Korea. Migration patterns were categorized into 5 patterns based on sequential transitions of "geographic origin-nursing school-hospital." Multiple logistic regression analysis was conducted to identify factors associated with working in non-metropolitan hospitals. Results: Nurses who grew up, graduated, and worked in the same region accounted for the greatest proportion (54%). Sixty-five percent had their first employment in the region where they graduated. Nurses tended to move from poor to rich regions and from non-metropolitan to metropolitan areas. Working in non-metropolitan hospitals was related to older age, the father having completed less than 4 years of college education, non-metropolitan origin, non-capital city school graduation, and a diploma (vs. baccalaureate) degree. Conclusion: Admitting students with rural backgrounds, increasing rural nursing school admission capacities, and providing service-requiring scholarships, particularly for students from low-income families, are recommended to address geographical imbalances.

Background: this study was designed to estimate whether specific risk factors could increase the postoperative complication rate of pneumonectomy for chronic complicated inf-lammatory lung disease. Material and Method: Eighty-five patients underwent pneumon-ectomy for chronic complicated inflammatory lung disease(tuberculosis, 67 ; bronchiecasis 11; aspergio- losis, 4; others, 3) between January 1991 and August 1998. We performed a univariated statistical analysis to identify preoperative and intraoperative risk factors associated with postoperative complications, Result: There was no operative mortality. There were a total of 18 postoperative complications(22.2%) Bronchopleural fistula(BPF) and empyema occurred in 5(5.9%) and 2(2.4%) respectively. General complication rate was significantly higher in patients with right-sided pneumonectomy(p=.029) extrapleural pneu-monectomy(p=.009) and intraoperative pleural spillage due to cavity or lesion perforation (p=.004). The prevalence of BPF and empyema was higher in patients with right sided pneumonectomy(p=.007) extrapleural pneumonectomy(p=.015) and intraoperative pl- eural spillage due to cavity or lesion perforation(p=.003) which is as the same results as gen-eral complication rate. Conclusion: The postoperative complication rate of pneumone-ctomy for chronic complicated lung disease is accptably low. But it is increase in patients with right sided pneumonectomy extrapleural pneumonectomy and intraoperative pleural spillage due to cavity or lesion perforation. therefore more careful and meticulous intra-operatve management are needed in right sided extrapleural pneumonectomy without intra- pleural spillage.
