This paper presents a new group for multilevel converter that operates as symmetric and asymmetric state. The proposed multilevel converter generates DC voltage levels similar to other topologies with less number of semiconductor switches. It results in the reduction of the number of switches, losses, installation area, and converter cost. To verify the voltage injection capabilities of the proposed inverter, the proposed topology is used in dynamic voltage restorer (DVR) to restore load voltage. The operation and performance of the proposed multilevel converters are verified by simulation using SIMULINK/MATLAB and experimental results.

This paper presents a novel topology for cascaded transformer sub-multilevel converter. Eachsub-multilevel converter consists of two DC voltage sources with six switches to achieve five-level voltage. The proposed topology results in reduction of DC voltage sources and switches number. Single phase low frequency transformers are used in proposed topology and voltage transformation and galvanic isolation between load and sources are given by transformers. This topology can operate as symmetric or asymmetric converter but in this paper we have focused on symmetric state. The operation and performance of the suggested multilevel converter has been verified by the simulation results of a single-phase nine-level multilevel converter using MATLAB/SIMULINK.

The purpose of this paper is to study to the nature and function of scientific inquiry and research methods, particularly as they apply to the influencing factors in library schools. For the variables used, they are the average cost per student for training, the total percentage placement in library and library-related work, the average salary for year, and the type of schools. In interpreting data using, t -test analysis of correlation and regression are applied.

Small and Medium Enterprises (SMEs) are suitable to provide employment with lower investment in densely populated countries like Bangladesh. A stochastic frontier model is used to evaluate performance of SME Banking of the commercial banks in Bangladesh. Input (Total Deposit, Cost of Fund and Salary Expenditure) and output (Finance to SME) data are collected on 45 banks which are dealt with SME for 13 quarters from $1^{st}$quarter of 2010 to $2^{nd}$quarter of 2013. Average performance of the SME banking is 0.716 in Bangladesh. That is, banks have opportunity to increase 30% performance in SME banking from the same inputs. Bangladesh Development Bank has lowest performance (0.540) while Eastern bank has the highest performance (0.753). Highest (0.743) and lowest (0.662) performance is observed during the second quarter of 2013 and fourth quarter of 2010 respectively. Inefficient Bank might be benefited by following the rules of efficient banks.

The purpose of this study was to make a survey of the operation of childcare facilities in rural regions through in-depth interviews with 5 facility principals. Owing to regional disadvantages, rural childcare facilities have many problems as follows: uneven distribution of facilities, shortage of teachers, financial difficulties, unsuitable programs for rural regions, insufficient reeducation of principals and teachers, and poor operations and accessibility for handicapped or very young children. The principals proposed that many conditions might be made better as follows: evenly distributing facilities in step with needs and supply, raising the salary of teachers of rural facilities, supporting the facilities themselves side by side with supporting children, improving 'childcare fee supporting system' of the Ministry of Agriculture and Forestry, developing and spreading programs suitable for rural regions, and promoting the reeducation of principals and teachers through online programs.

The purposes of this study were to examine the motivation of career choice for chefs in luxury hotels through IPA analysis based on the differences between importance and satisfaction, and to investigate the impact of motivations of career choice on job satisfaction. The results are as follows. First, "matched aptitude" and "interest in cook" were found as factors of importance and satisfaction. Second, sufficient reward should be provided through incentive, increasing salary, and promotion. Third, the system of internship and temporary employee should be revised, and the motivation should be provided through performance-based reward and incentive system. Fourth, fair personal evaluation, transparent promotion system, fair reward system should be required to increase job satisfaction. Fifth, internal environment is important rather than social reputation or popularity for those who consider chefs as future career.

This study proposes a means of guiding undergraduate research assistants programs in a more positive direction. This will be achieved by researching the reality of the programs operated in engineering departments for graduate school students and by analyzing the problems thereof. To achieve this objective, a literature study and research were conducted, which comprised of a survey on 204 graduate school students within the metropolitan area of Korea. The results of the study demonstrated that experience as an undergraduate research assistant has a positive influence on the adaptation to and life in graduate school. However, the role of the student and the level of salary varied depending on the role of the student, based on the capacity and support of individual professors. Thus, it is deemed that there will be a need for systematic program improvement and the development of a program that can provide significant academic activities, rather than simple experimental assistance.

Using the data of Economically Active Population Survey and GOMS, we analyze youth employee's labor mobility. We found the causes of the youth employee's labor mobility as follows: work environment, salary, enterprise's vision, job satisfaction, job mismatching, organizational culture, mismatching of work and housing and so on. On the basis of results, we proposed a step by step solutions. The resulting policy implication is that rather than raising job finding rate of the unemployed youths, we need to focus more on reducing job mismatching.

The aim of this study is to analyze determinant factor on the strike action among hospital laborer in Korea. We collected data for 10days from 12 to 22 July, 2013. This study was surveyed 405 laborer in university hospital was located in the Seoul city and Gyeonggi-do. It was found as follow. There was statistically significant difference in the strike propensity and sub-domain on the job dissatisfaction by sex, age, education, wedding, occupation, position, salary, number of years of employment, position in labor union for strike action(p<0.05). From the multiple regression analysis, it was found that determinant factor on the strike action was occupation, strike propensity(sense of duty, after vote, depend on compensation) which was statistically significant difference(p<0.05). As a result, we suggest that hospital administrator must solve the problem related welfare benefits and personnel system in university hospital for preventing strike.

The purpose of this study is to analyze consumption expenditure patterns over family life cycle. The data used in the study is the 1994 Survey data from Annual Report on the Family Income and Expenditure Survey. The study sample included 26,980 salary and wage earners’ households living in cities. The family life cycle was classified into six stages and items of expenditure were classified into 12 categories. Frequency distribution, mean, one-way ANOVA, Scheff test, and regression analysis were used to analyze the data. The major findings of this study are as follows : First, the average consumption propensity differs among family life cycle. Second, the amount and budget share of consumption expenditure for each expenditure category differ significantly among family life cycle in all expenditure categories. Third, family life cycle is found to be a significant factor on expenditure of food and education, and also on budget share of education.
