Recently, in Korea, a few construction companies have been tried to develop a management system, which is able to integrate schedule and cost. In spite of these attempts, however, advanced management techniques can be hardly applied under the BoQ based management system. In order to improve these problems, many studies have been peformed, but yet could not overcome practical limitations. Besides, the application of historical data is below the level since it is so difficult to accumulate and feed-back historical data under the unique character of construction industry. Consequently, lots of time and effort have being wasted to establish control criteria. The newly generated Information is not systematically managed as well. Therefore, this study suggests Integrated Construction Management System complemented the existing practical problems.

The purpose of this thesis is to study on the philosophical analysis model and its methodological application of information systems research evaluation from critical realist perspective. Fist of all, I examine ontological epistemological methodological assertions of critical realism. Because the philosophy of critical realism is an opportunity for information systems study. I examine Dobson and Mutch's critical realist perspective on actors-structure model. I suggest a critical realist actors-praxis-structure model. This model provides the potential for a new approach to social investigations in its provision of an ontology for the analytical separation of structure and agency. Of most importance might be the incorporation of non-humans into the analysis of social interaction and of technology into the elaboration of structures. I also examine Tsoukas's critical realistic meta-theory of management. I suggest a critical realist IS management model. This model elucidate the nature of management and delineate the scope of applicability of various perspectives on management. The causal powers of management reside in the real domain and, taken together, their logics are contradictory, the effects of their contradictory composition are contingent upon prevailing contingencies. I analyze Carlsson's theory of design knowledge. His framework builds on that the aim of IS design science research is to develop practical knowledge for the design and realization of different classes of IS initiatives, where IS are viewed as socio-technical systems and not just IT artefacts. The framework proposes that the output of IS design science research is practical IS design knowledge in the form of field-tested and grounded technological rules. The IS design knowledge is developed through an IS design science research cycle. In conclusion, I think that IS actors-praxis-structure model, meta-theoretical IS management model, and IS design knowledge model according to critical realistic approach are very useful for IS research evaluation. Nevertheless, important problems are left not resolved.

Purpose One of the success factors of information system projects is to reduce requirements uncertainty through user engagement. So, in many recent IS development environment, a business analyst or business analysts are positioned between users and developers to drive user engagement to reduce requirements uncertainty. But, there are few studies that research about the competencies of business analysts for training and staffing. So, this study analyzed which underlying and practical competencies that positively influence user engagement are required. Design/methodology/approach The level of underlying and practical competencies required for business analysts and the level of user enagement in the IS development environment are collected through the survey. And, the causal relationship between the construct concepts which are underlying competencies, practical competencies and the user participation is analzed through the PLS analysis. Findings The results of this study show that the practial competencies of business analysts that positively have a significant impact on user engaement were studied as requirements development skills. Additionally, the underlying competencies of business analysts which have a significant impact on requirements development skills were examined as business knowledge and interaction skills rather than technical knowledge and communication skills.

The purpose of this study was to research adolescents' practical awareness about the contents(classify them into four units, choice and dressing of clothes, textile and management of clothes, design and sewing of clothes, knitting and embroidery) clothing and textiles education in their real life. This is the investigation of which 730(middle school students 246, high school students 248, university students 236) girl students located in Junrabukdo and Choongchungnam. In this statistical analysis. SPSS 10.0 for Windows Program was utilized to calculate percentage, mean and standard deviation. Also, these materials wert verified by t-test, One-way Anova. The main results of obtained this study are as follows. Adolescents' practical awareness about the contents of clothing and textiles education in their real life appears to be low(only 8 items were over median point of 3.0) There was a significant difference in practical awareness of contents of clothing and textiles education according to early$.$middle$.$latter adolescents and demographic variables differed significantly. These results should be provide fundamental information for improving students' critical practice in their real life. Since this study has touched only limited research on the topic of clothing and textiles education, it is essential that further research covering a wider array of themes be done in the future.

This study was to review the child research articles in the field of home economics in Korea for the last two decades and to evaluate the child studies in terms of home much the child research had contributed to society. For the purposes of this study all the child research articles that had been published in the three representative academic journals of Korea were reviewed. A framework to evaluate child studies was decided in accordance with objectives of the research theoretical and practical, Theoretical studies imply ones dealt with child development and personality parent-child relations development of measures and thoughts on children while practical studies mean the research on development of parent education programs child education programs mental health of children wellbeing of children and child welfare policies. Results of qualntitative analysis in this study showed increases in numbers of both theoretical and practical studies. Practical studies however occupied j st 4-12% of all the research article published in the last 20 years. The Results of this study indicated researcher' low involvement in pratical studies. Researchers in the field of child studies had most frequently conducted research on child development and parent-child relations which were conducted based on theoretical knoledges from the West. For the practical child studies there were some studies on developing parent education programs and a few articles dealt with child welfare policies and wellbeing of children for two decades. Furthermore the major variables of the practical studies were analyzed and evaluated with respect to their contribution to society as well as socializing child relate issues. Finally the reasons of scholars' low involvement in practical studies and some suggestions for further studies to deal with practical child issues were discussed.

For practical education, many practices using various practical equipments have to be provided to students. In this study, the application of learning curve to represent student's learning process in a practical education using a equipment was studied. Learning curve model was originally developed in production management and based on human performance in human factors aspects. In this study, the application of learning curve model was studied on the eye tracking system, which is used to evaluate the usability of a product in design area. As a case study for its applicability, practical education for eye tracking system was provided to three students and then task completion times were measured for hardware system setup and gaze image recording. Learning curves were estimated for two tasks and then task completion times were predicted using the learning curves. Through ANOVA(analysis of variance) and correlation analysis, the applicability of learning curve to practical education was analysed. As the result, learning curve could be effectively applied to practical eduacation using equipment.

Objectives : The purpose of this study was to examine the problems with the current practical examination, to suggest some of the right directions for that and to facilitate the improvement of the exam. Methods : The subjects in this study were the selected professors involving professors in charge of practice and the selected clinical dental hygienists who had ever served as the graders of the national practical exam. Results : A direct practical test was required in the national practical exam (77.3%), and educational facilities(79.2%)(p<0.05). They didn't put confidence in the national practical exam(81.0%) nor viewed the items about the removal and detection of dental calculus as appropriate(58.5%), either. Specifically, the items were considered to be more inappropriate by the professors in charge of practice(74.3%) than by the other professors and clinical dental hygienists(p<0.05). Concerning ways of administering the national exam, the largest group preferred that a professional evaluator should evaluate students in person by visiting their colleges(66.8%). Conclusions : The above-mentioned findings illustrated that both of the dental hygiene professors and the clinical dental hygienists thought the current national dental hygienist practical exam would absolutely be necessary since it exerted a great influence on education and educational facilities, and that the national exam should be improved to gain more confidence, to solve comprehensive problems and to ensure the efficiency of administration.

Company A, an embedded system manufacturer, has been managing multiple development projects. Executives need to understand the risk level of every project and prioritize resource distribution. Traditional project monitoring tools or excel sheets are too complex for calculating the risk factors across a functional organization. Two new charts, "Spear-head Chart" and "Float Chart" were designed to assist high level decision making processes. Two charts were used for weekly executive meetings in order to monitor project progress and rectify project direction. One page graphical monitoring tools in Company A are good enough for high management decision making. Authors explain the characteristics of two charts and propose its practical implementation in real working environment. Spear-head chart was also implemented as a system.
