Abstract

The study aims to compare the perceptions of self-efficacy and job satisfaction level between Korean and Non-Korean teachers. Questionnaires based from literature review were administered to 44 teachers at Hanseo University. Descriptive statistics, Pearson Product Moment of Correlation and ANOVA have been used to analyze the data in the study. According to the result, there is no significant difference on the level of job satisfaction and the perception of efficacy between Korean and Non-Korean teachers. On the other hand, there is a significant positive relationship between teacher efficacy and job satisfaction level.

Abstract

Objectives: To identify the predominance of Total Quality Management (TQM) practices in small and medium sized manufacturing companies in the Philippines and its relationship to financial performance. Methods: Questionnaires were administered among the owners/managers of the 50 small and medium manufacturing firms which were chosen through multi-stage random sampling. The questionnaire was composed of questions relating to quality practices in terms of management commitment and leadership, continuous improvement, total customer satisfaction, employee involvement, education and training, and reward and recognition. Descriptive statistics and Pearson Product Moment of Correlation were used to analyse the data in the study. Findings: The results reveal that the TQM practices in terms of management leadership and commitment, customer satisfaction, and continuous improvement are highly predominant while employee involvement, training and education, and rewards and recognition are only moderately predominant. Furthermore, aside from continuous improvement which was found to have a significant relationship to the solvency of the companies, there was no significant relationship between the other areas of TQM and the financial performance of the companies in terms of liquidity, solvency and profitability. These results run parallel with the fact that the rewards of TQM are highly long-range which means that any investment in the quality efforts now may not necessarily lead to any positive improvement in financial performance at once, or in the short term. This is the reason why there is a high degree of management commitment necessary in order to keep the improvement efforts afloat. This study has produced an important insight that a long-term dedicated SME quality development campaign can be an ideal strategy to improve productivity. Improvements: A comparison on the adoption of TQM between companies in terms of time period would give insights of the effects of TQM, if any, when conducted over long-term.

Abstract

LEACH (Low Energy Adaptive Clustering Hierarchy) is the first network protocol that uses hierarchical routing for Wireless Sensor Networks (WSN) to increase the life time of network. Research on WSN has recently received much attention as they offer an advantage of monitoring various kinds of environment by sensing physical phenomenon, such as in-hospitable terrain, it is expected that suddenly active to gather the required data for some times when something is detected, and then remaining largely inactive for long periods of time. So, efficient energy saving schemes and corresponding algorithms must be developed and designed in order to provide reasonable energy consumption and to improve the network lifetime for WSN. WSN are networks consist of large number of tiny battery powered sensor nodes having limited on-board storage, processing, and radio capabilities. Nodes sense and send their reports toward a processing center which is called sink node or Base Station (BS). Since the transmission and reception process consumes lots of energy for data dispensation, it is necessary to designing protocols and applications for such networks has to be energy aware in order to prolong the lifetime of the network. The proposed, LEACH-PR (Low Energy Adaptive Clustering Hierarchy - Power Resourceful) protocol includes clustering, routing and radio propagation technique by balancing the energy consumption of sensor nodes to improve the efficiency of data transmission and prolonging the network lifetime. The goals of this scheme are, increase the stability period of network, and minimize the energy consumption. The performance analysis of proposed LEACH-PR is compared with I-LEACH (Improved LEACH), EHE-LEACH (Enhanced Heterogeneous LEACH), and EEM-LEACH (Energy Efficient Multi-hop LEACH) protocols and concluded that, the LEACH-PR has significant improvement over in terms of lifetime of network, both in homogeneous and heterogeneous environments.
