This study was conducted to evaluate the efficacy of herbicide mixtures of benzobicyclon and carfentrazone-ethyl in direct-seeding flooded rice. The efficacy of benzobicyclon mixtures and carfentrazone-ethyl mixtures was greater than that of pyrazosolfuron-ethyl + pyriminobac-methyl GR. Herbicide mixtures with benzobicyclon controlled average 97% and herbicide mixtures with carfentrazone-ethyl controlled average 95% 60 days after application. When compared with untreated control, no visual injuries were detected at single and double dosage of herbicide mixtures. The yield of rice increased in both benzobicyclon and carfentrazone-ethyl treatments when compared with pyrazosolfuron-ethyl + pyriminobac-methyl GR. Based on these data, combinations of these herbicides can be applied to provide effective weed management in rice field.

The concept of social entrepreneurship (SE) is gaining attention in developing economies for the purpose of greater societal welfare maximization. Still, findings in the field of SE studies have been riddled with conflicting results and counterstatement. Also, the determinants of developing SE are not robustly investigated in developing economies like Bangladesh. This context has mobilized the authors of this current study to focus on determining student's intention to pursue SE as their career choice. Hence, the study aims to examine the predictive determinants of social entrepreneurial intentions (SEI) among Bangladeshi students. The study has investigated the influence of entrepreneurial self-efficacy, social support, prior experience, and educational support on SEI. The survey was conducted from a public university of Bangladesh, and 231 students participated in the study. Questionnaire items under each construct variable have been adopted from pre-tested research studies. Five-point Likert scale questionnaire was applied to measure the variables. SPSS version 23.0 has been used for statistical analysis through which correlation and multiple regression analysis were conducted to measure the impact of the independent variables on SEI. Results exhibited that self-efficacy, social support, and educational support positively and significantly predicted SEI, while prior experience does not influence SEI.

This study empirical analysed how senior's technical stress and self-efficacy affected entrepreneurial intentions and whether resilience functioned as a mediating effects between them. 207 data were collected from the field survey questionnaires administered to a convenience sample of senior men and women aged 40 and over who had entrepreneurial intentions. For hypothesis testing, the IBM SPSS Statistics 24.0 was used. Frequency analysis, exploratory factor analysis, correlation analysis, and hierarchical regression analysis were conducted. Empirical studies showed as follows. First, technical stress affected senior's entrepreneurial intentions. Second, self-efficacy turned out to affect senior's entrepreneurial intentions. Third, resilience came out to have a partial-mediating effects between technical stress and the senior's entrepreneurial intentions as well as between self-efficacy and the senior's entrepreneurial intentions. These research outcomes supported the preceding studies that self-efficacy played key roles in maximizing senior's entrepreneurial intentions and demonstrated the importance of self-efficacy as an independent variable for seniors to promote entrepreneurial activities with an intention of starting a new business. Furthermore, the technical stress newly introduced as an independent variable was found to be the next most important factor after the self-efficacy. The study also confirmed that the resilience has been doing an partial-mediating effects. However, it appeared that the technical stress affected the will of start-up, but it appeared to be a positive relationship. For generalization of this finding, further studies are required.

To determine clinical nursing instructors' teaching efficacy, students' clinical practice satisfaction, and confirm between correlation, and develop a plan for operating nursing education efficiently for clinical practice. Clinical practice could create an optimal learning situation. We applied CNITEs and CPS to measure clinical nursing instructor teaching efficacy and clinical practice satisfaction. The differences in teaching efficacy by the general characteristics were measured and analyzed; the higher the level of the participants' education, position, clinical career, and clinical teaching career, the higher their teaching efficacy. The higher the age at clinical practice, the higher the clinical efficacy of clinical practitioners with clinical career and higher education level students were more satisfied with the practice subject and nursing instruction than other categories. Therefore, in order to increase the satisfaction of nursing students' practice in the clinical field, we hope to improve various things that can be used not only teaching efficacy but also in clinical practice satisfaction.

The purpose of this study was designed to help the operation of the hospital organization through analysis of factors influencing organizational commitment of general hospital nurses. 129 nurses in general hospitals were targeted in G City. This study was conducted to analyze the effects of group efficacy, self-efficacy, and nursing professionals on organizational commitment. T-test, ANOVA, Pearson's correlation coefficient, Descriptive statistics and multiple regression were used. Stepwise regression analysis found that organizational commitment was affected by group efficacy(β=0.240, p =.003), nursing professionalism(β=0.229, p =.004) and daytime work(β=0.249, p =.003), The F statistic was 10.478 (p <.001). Therefore, in order to improve organizational commitment, it will be necessary to prepare communication programs and cooperation programs per unit to improve collective efficacy. In addition, it is necessary to improve the system, such as a system dedicated to night workers, so that the working hours of nurses in general hospitals can be maintained constant. In addition, it is necessary to develop a support program so that nursing professionals do not decrease due to disappointment in reality in the nursing field.

The growth of e-commerce market requires more delivery packagings, which protect goods from the damage factors on the delivery. In this study, we have analyzed the distribution environment data (vibration and impact) measured in previous study and compared with global standards (ISTA, ASTM), so that we developed the testing method for Field-to-Lab simulation suitable to the domestic delivery. In order to verify the efficacy of this method, we took the Field-to-Lab tests for 3 packaged products (detergents set, glass tableware set, small furniture), which has been frequent breakages or damages on the actual delivery by e-commerce order, so that we could find out the test results were similar to those of the actual delivery occasions. In addition, we could perform redesign and improvement of the parcel delivery packagings for safe transportation by taking this Field-to-Lab test repeatedly. This test methods was finally proposed to be Korean industrial standard (KS), and is expected to be useful as a designing tool for the packaging optimization between protecting goods and reducing packaging waste.

This study is about the effect of the founder's self-efficacy on the sales of the founding company by focusing on the factors that are currently emphasized in the founding education. In particular, this paper starts from the consciousness of the problem that the education that is being implemented to achieve the purpose of successful start-up among various government-based start-up support projects is failing to produce many start-up failures. Entrepreneurs cannot be assessed by objective financial data, but there is a high degree of uncertainty that should be determined based on their personal and learning abilities. In addition, many previous studies, which are likely to be successful when there is a high self-efficacy in a specific field due to the influence of factors such as personal experience or learning, will answer the direction of support for start-up companies. This study focuses on the impact of the founder's self-efficacy on the sales of the founding firms, especially the sales that are the key to the survival of the founding firms. This study has six major studies. First, to analyze whether the self-efficacy of entrepreneurs with respect to entrepreneurship affects the sales of entrepreneurs. Second, to analyze whether the self-efficacy of entrepreneurs with respect to market orientation affects the sales of entrepreneurs. Analysis of whether the founder's self-efficacy affects the sales of the founding firms. Fourth, analysis of whether the founder's self-efficiency affects the sales of the founding firms' understanding of management environment changes. An analysis of whether efficacy affects the sales of a start-up company, and sixth, an analysis of whether the founder's self-efficacy of business model building ability affects the sales of a start-up company. As a result of the empirical analysis, this study found that the self-efficacy of entrepreneurs on product differentiation capability and business model building capacity had a positive influence on the sales of entrepreneurs. The self-efficacy had a positive effect on self-efficacy, and the customer orientation had a positive effect on self-efficacy on business model building capacity. Also, it was confirmed that a path exists between the components of self-efficacy and that self-efficacy through the path has a positive effect on the sales of the start-up company. Therefore, the results of this study suggest the implications of establishing such a path and strengthening self-efficacy to create the survival and start-up performance of a start-up company if the goal of the start-up company is to survive when implementing various support projects for the start-up company.

ABSTRACT -- Recently, a method of magnetically-enhanced discharge columns is considered to increase the luminous efficacy of discharge lamps, which is based upon the face that the diffusion motion of charged particles in the discharge column strongly depends on the applied magnetic fields. This study investigates the effect of applied transverse magnetic fields on the light output of low-pressure Hg-Ar discharge. As a result, it is found that the electric field in the positive column increases according to the applied megnetic field, which causes an increase in the total light output. And this effect is much more pronounced upon the spectral line originating form the higher levels.
