The present research aims to examine whether learning from the supervisor influences readiness for change with the mediating impact of planfulness. Drawing upon the theory of planned behavior, it is hypothesized that learning from the supervisor positively impacts planfulness ability in individuals, which in turn enhances the readiness for change. Through using convenience sampling, the sample of 451 was collected from employees working full-time in the manufacturing and I.T. service organizations in India. Structural equation modeling and regression analysis indicate that learning from the supervisor is positively associated with readiness for change and planfulness. Additionally, planfulness fully mediated the relationship between learning from the supervisor and readiness to change. The findings of the present research highlight that continuous support and learning from the supervisor enhances the planfulness ability of the individual and consequently enhances individual readiness for change. The current research is pioneering in testing the hypothetical model associating learning from the supervisor, planfulness, and readiness for change.

The purpose of the study was to apply and to expand the six sigma to reduce waiting times for computed tomography (CT) examination which manipulated by the department of radiology. It was preceded by DMAIC (Define, Measure, Analyze, Improve, and Control). In the stage of definition, it wereselected for total 5 critical to quality (CTQ), which were the kindness, the waiting time, the examination explanation, the waiting day and the waiting stand environment, that increased the reserved time of CT examination. In the stage of measurement, the number of examinations and of reservation waiting days performed and resulted in final CTQ(Y) which measured each 1.68 and 1.85 sigma. In the stage of analysis, the examination concentrated on morning time, non-scheduled examination of the day, the delayed time of booking, frequent telephone contacting and equipment malfunction were determined as variable key causes. In the stage of improvement, it were performed with expansion of the examination in the morning time, integration of laboratories that used to in each steps, developing the ability of simultaneous booking schedule for the multiple examinations, developing program of examination request, and the customer management team operations. For the control, the number of examinations and reserved waiting days were measured each 3.14 and 1.13 sigma.

Achieving situation awareness is especially challenging for real-time data stream applications because they i) operate on continuous unbounded streams of data, and ii) have inherent realtime requirements. In this paper we showed how formal data stream modeling and analysis can be used to better understand stream behavior, evaluate query costs, and improve application performance. We used MEDAL, a formal specification language based on Petri nets, to model the data stream queries and the quality-of-service management mechanisms of RT-STREAM, a prototype system for data stream management. MEDAL's ability to combine query logic and data admission control in one model allows us to design a single comprehensive model of the system. This model can be used to perform a large set of analyses to help improve the application's performance and quality of service.

The objective of this study is to forecast the operational continuous ability using Artificial Neural Networks in battalion defensive operation for the commander decision making support. The forecasting of the combat result is one of the most complex issue in military science. However, it is difficult to formulate a mathematical model to evaluate the combat power of a battalion in defensive operation since there are so many parameters and high temporal and spatial variability among variables. So in this study, we used company combat power level data in Battalion Command in Battle Training as input data and used Feed-Forward Multilayer Perceptrons(MLP) and General Regression Neural Network (GRNN) to evaluate operational continuous ability. The results show 82.62%, 85.48% of forecasting ability in spite of non-linear interactions among variables. We think that GRNN is a suitable technique for real-time commander's decision making and evaluation of the commitment priority of troops in reserve.

This study examines the effect of managerial ability on managers' opportunistic reporting discretion in recognizing the goodwill impairment losses after the adoption of K-IFRS. Cross-sectional regression results show that goodwill impairment losses are not recognized timely at the time of the goodwill impairment symptom, but rather managers make bad use of goodwill impairment losses as tools of income smoothing and big-bath. Managerial ability is not directly related to the recognition of goodwill impairment losses, but firms with more able managers recognize timely goodwill impairment losses when the symptom of goodwill impairment exists, and they use less income smoothing when the firms' expected pre-impairment earnings are abnormally high. This study is the first research to consider the relationship between managerial ability and manager' earnings management in goodwill impairment accounting.

When certificates of qualification relating to computer have shown up like dam water and meeting the age of office automation (OA) utilizing computer throughout the community, and at the point of time when the promotion of efficiency of duty is attempted by utilizing internet, the improvement plans should be groped for to expect to cultivate the national industrial manpower efficiently and by easily approaching the related OA certificates of qualification related to computer so that everyone can acauire the additional points for recognition of credit, entering company and promotion by the dimension of public trust, recognition degree, practial using level in actual affairs, reliability of problems and after manpower management of the certificates of qualification less expensively and saving time. the concrete plans are as follows: First, in the standard of making questions for the examination of 'Computer Utilizing Ability' executed by the chamber of commerce and Industry, there is the independent examination, but by inserting the presentation portion in the higher grade and middle grade, it should be contributed to improve office efficiency both in mane and reality. Second, though the internet retriever's examination is executed by the nongovernment specialized examination, since it is actually widely utilized in the office activities due to universality of using internet, it is now the time to newly establish and accommodate it as the national examination of 'internet Utilizing Ability', not the interest specialized retriever. Third, the applicants, shall take examination for the nongoverment certificate of qualification or enterprise's certificate of qualification at the date and place designated by the applicant, but there are much restrictions for the national certificate of qualification, so the date of examination shall be decided flexibly and efficiently to give chances to students by adjusting to the semesters of the students. Fourth, in this rapidly changing age of the informationalization community, the acquisition of the certificates of qualification through the university and the designated and entrusted educational institutes should be increased the proportion of activation to become officially recognized, and the extent of special treatment for obtainers of the certificate of qualification should be expanded to equip manpower competitive power in the age of informationalization.
