This paper presents the empirical research results conducted in a Swedish care organization for elderly and handicapped. The objective of the research was to empirically assess the implementation and practices of a quality system (ISO 9000) from an organizational change and development perspective. The empirical data were collected through multiple methods; interviews were carried out with key-persons and leadership in the organisation and surveys were conducted to all employees. Interactive methods have been applied to various groups in the organisations e.g., directors, supervisors, and the leadership of the quality project and the local politicians. The empirical findings indicate, among others, that the implementation processes were received and perceived differently in the different parts of the care organisation due to different leadership strategies and employee involvement policies. Other critical factors such as acceptance, resistance, motivation, commitment, the role of leadership, learning possibility, etc. have also been investigated, analysed and discussed. Finally some recommendations on how to approach organisational change as well as strategies for implementing a quality system in the care sector are presented.

Construction safety should be considered prior to any other factors to execute construction projects smoothly and reduce the social expenses. Especially, the safety education is very important to the lives of labors and to control the four resources such as time, money, quality and safety. On this research, the present situation and related regulations of safety education are reviewed and the education contents and realities of the safety empirical education places are surveyed. Also questionnaire to education lecturers is performed to understand the satisfaction level of the education programs of the education places. Finally, the improvement directions are suggested to inspire trainees based on the results of the research.

Usability evaluation(UE) experiments are conducted to provide UE practitioners with guidelines for better outcomes. In UE research, significant quantities of empirical results have been accumulated in the past decades. While those results have been anticipated to integrate for producing generalized guidelines, traditional meta-analysis has limitations to combine UE empirical results that often show considerable heterogeneity. In this study, a new data mining method called weighted bi-clustering(WBC) was proposed to partition heterogeneous studies into homogeneous subsets. We applied the WBC to UE empirical results and identified two homogeneous subsets, each of which can be meta-analyzed. In addition, interactions between experimental conditions and UE methods were hypothesized based on the resulting partition and some interactions were confirmed via statistical tests.

In this study daily flow rates and delivered pollutant loads of Nakdong river basin are simulated with modified TANK model and minimum variance unbiased estimator. Based on the simulation results, flow duration curves, load duration curves, and delivery ratio duration curves have been established. Then GIS analysis is performed to obtain several hydrological geomorphic characteristics such as watershed area, stream length, watershed slope and runoff curve number. Finally, multiple regression analysis is carried out to estimate empirical equations for pollutants delivery ratio. The results show that there is positive relation between the flow rates and delivery ratios, and the proposed empirical formulas for delivery ratio can predict well river pollutant loads.

Construction companies with the highest proportion in death crash has been devoting much effort to prevent the crash accidents. In general, a crash-proof worker has been wearing a seatbelt. However, the G construction company had happened in industrial settings when workers fail to abide by the rules. The Carabiner, one of the composing of Safety Belt, must endure the Allowable Load. In this study, the Industrial accidents and cause of the crash analysis in G Construction company is performed by empirical research. And we have been studied the empirical research to setting up of the allowable limit for Carabiner.

This paper examines that determinants of BAOMAI, (i.e., behavior of Chinese tourist bulk purchase in duty free shop) with analytical framework and empirical tests. The results of applying the structural equation modeling to 196 samples suggest that Chinese tourist consumption orientations (conspicuous/compulsive/unplanned consumption) have a positive effect on BAOMAI decision value chain (perceived value and loyalty). The marketing mix of duty free shop as control variables in research framework also have a positive effect on BAOMAI perceived values (functional/social/emotional value). This paper has a contribution to prior literatures: the first empirical analysis on BAOMAI determinants with exploring scholarly definition.

The use of statistical methods in the MIS research is increasing. However, there has been a meager attempt to critically evaluate the use statistical methods in MIS research papers. The review of 33G papers published in MIS Quarterly from Volume 1 to 14 resulted in three findings; (1) the portion of empirical research has been gradually increasing compared with non-empirical research, (2) univariate parametric statistical methods are most popular among MIS researchers, (3) researchers do not comply with the writing code of scientific research. This paper disscusses what errors MIS researchers might commit in using statistical research methods and how to prevent those errors in each of three stages of research, research design phase, statistical inference phase, and interpretation phase.

Nursing theory is used to explain the goals and functions of nursing and improve practical affairs by providing information and knowledge about the principles which become the foundation of nursing practical affairs. Theoretical analytical compliance with C-T-E (Conceptual-Theoretical-Empirical) structures by Fawcett (1999) whose evaluation method illustrates the relationship of conceptual models, theory, research and structure. The evaluation allows the nurse to visualize the connection, evaluate research, and reduce errors in research. Consequently present doctorate dissertations in nursing science are theoretical propriety, connection in the structure of concepts, theory, research methods, and evaluation to reduce errors in future research plans and division of theoretical development process. So the following verifies logicality, propriety, and reliability which must apply to research in various different fields.

Recent trends in business are characterized by recognition of the importance of knowledge assets. Especially, this phenomenon is receiving more momentum as our society goes digital rapidly. The concept of Knowledge Management has long been used as an effective way of restructuring the management process of a firm. In literature regarding knowledge management, a number of successful cases were reported, where knowledge-based management activities could dramatically enhance a firm's strategic performance for years. However, there exists very little research investigating the effect of knowledge management on corporate competitiveness. Researchers as well as practitioners need more rigorous results about such issues, especially how much the knowledge management strategic initiatives may have an influence on the firm's competitiveness. In this sense, we need an empirical study adopting statistical approaches due to the existence of abundant knowledge management case studies. To fill this research void, this study proposes a research model testing whether knowledge management activities could improve corporate competitiveness. We collected 321 valid questionnaires from participants in knowledge management activities in the tourism industry and applied a structural equation model. Empirical results showed that knowledge management activities have a positive impact on knowledge management efficiency and finally corporate competitiveness. We hope that this study will shed light on further rigorous studies considering tourism industry as a major strategic activity.

This study is an empirical research in order to clarify whether or not the correlation between the satisfaction of users that is the performance measurement factor and the following three:(1) the attitude of users as an individual characteristic, (2) the supports of organization as an organizational characteristic, (3) the routine degree of jobs as an job characteristic, is the same as the previous study results. In addition, another empirical research was done to make clear how organizational supports and routine degree change the attitude and satisfaction of users. This study put a particular emphasis on the moderating effect because the study of this issue has not been done in any previous research. 38 corporations, whose computerization has already been made to some extent and who are listed on the stock exchange market as a leader group, was selected for research, given some hypotheses on the basis of theoretical studies. As results of this empirical study, first, the supports of organization and the routine degree of jobs changed the attitude of users, which was the same as the previous studies. Moreover, the supports of organization, the routine degree of jobs and the attitude of users had an influence on the satisfaction of users. Second, in respect of the correlation between the attitude of users and the satisfaction of users, the routine degree of jobs showed a moderating effect, but the organization supports did not show any moderating effect.
