This research proposes a new risk analysis method in order to guarantee successful performance of construction projects. The proposed risk analysis methods consists of four phases. First step, AHP model can help contractors decide whether or not they bid for a project by analysing risks involved in the project. Second step, the influence diagraming, decision tree and Monte Carlo simulation are used as tools to analyze and evaluate project risks quantitatively. Third step, Monte Carlo simulation is used to assess risk for groups of activities with probabilistic branching and calendars. Finally, Fuzzy theory suggests a risk management method for construction projects, which is using subjective knowledge of an expert and linguistic value, to analyze and quantify risk. The result of study is expected to improve the accuracy of risk analysis because three factors, such as probability, impact and exposure, for estimating membership function are introduced to quantify each risk factor. Consequently, it will help contractors identify risk elements in their projects and quantify the impact of risk on project time and cost.

In this paper, some applications of natural language processing techniques for information retrieval have been introduced, but the results are known not to be satisfied. In order to find the roles of some classical natural language processing techniques in information retrieval and to find which one is better we compared the effects with the various natural language techniques for information retrieval precision, and the experiment results show that basic natural language processing techniques with small calculated consumption and simple implementation help a small for information retrieval. Senior high complexity of natural language processing techniques with high calculated consumption and low precision can not help the information retrieval precision even harmful to it, so the role of natural language understanding may be larger in the question answering system, automatic abstract and information extraction.

In this paper, an assistive device for a knee joint to help a disabled person to stand up by supporting power is presented. The device is designed and controlled by using damping characteristics of the MR (Magneto-Rheological) damper. The MR damper helps the person to sit slowly and safely. A DC motor supports muscle power in the case of standing motion. Thus the device helps the disabled person to sit down and stand up. Through the experiments, it is feasible that an assistive device can help the disabled person to standup according to the foot pressure change.

Purpose: The purpose of this study was to help understand the life and illness-experiences of focusing on a positive lifestyle, patients with Parkinson's disease, Method: The present study adopted a ethno graphic methodology. The participants for this study were 4 men and 3 women, who were treated for Parkinson's disease. Data was collected by an interview and participant observations from August 2003 to September 2004. Tape-recorded interviews were transcribed after the interview and classified and described to realistic tale. Result: Patients with Parkinson's disease experienced the stage of retake-off pursuing positive life by overcoming the acceptance process of illness including the stage of recognition of change, the stage of disruption and the stage of acceptance. The factors of positive life of Patients with Parkinson's disease were their strong will and social support. Conclusion: This study may be used in future studies as an important resource to develop nursing intervention strategies and programs for patients with Parkinson's disease that can help the patients to achieve strong willingness and positive life in Korea.

The purpose of this study is to help for an in-depth understanding of their thinking process by observing and analyzing the response found by two elementary school students, Through this study, the following findings could be obtained. First, two students have a tendency trying to solve the complex situation at first. Second, we could know that it is an important factor in discovering the pattern to predict it. Third, we could know that the activity of reconstructing the data meaningfully is an important factor in discovering the pattern. Fourth, it is an important factor in finding the pattern to work organically the activity of predicting it with the activity of reconstructing the data meaningfully. We hope that this study offers the help for an in-depth understanding of students's thinking process.

The purpose of this study is to develop and apply effective teaching strategies and program for the gifted-in-science. The teaching material for the gifted students was focussed on microscope. This study consists of three steps according to the enrichment triad model of Renzulli. Firstly, the gifted students investigate and express themselves for theological backgrounds, for examples, kinds, structure and use in various ways of microscope. It is to provide basic data for the effective ideas and interest which help students have the appropriate microscopic conceptions. In the second step, it contains understanding of a term and function of microscope, making of simple microscope, principle of a statue focusing and size estimation of an outline of subjects by scientific investigation activity. Lastly, it focussed on enlargement of post-learning through investigation of relationship with inter-science and experiments using microscope. Therefore, it was concluded that this study may help teachers reconsider scientific program development for the gifted or enriched students and to be successful in the teaching-learning processes.

The present research investigated gender-specific response strategies for dealing with peer victimization of preadolescents. Furthermore, coping strategies were explored as moderators of the link between peer victimization and internalizing problems. The participants were 466 preadolescents. Peer victimization, coping strategies, and internalizing problems were assessed through self-report questionnaires. Results showed that girls had significantly higher scores on help seeking, avoidant strategies, and ruminative strategies than boys. In addition, use of avoidant coping and seeking help minimized the effects of peer victimization on internalizing problems in girls. Ruminative coping exacerbated the influence of peer victimization on internalizing problems for both boys and girls.

Traditional procurement methods have revealed many disadvantages especially the adversarial relationship between parties. After several decades of application, partnering has shown that it is an innovative arrangement that help to reduce many problems having existed in traditional arrangement. It can provide a win-win working attitude in a construction project. Partnering in construction has been applied in several ways in recent years in Vietnam. This mechanism can help both local and foreign construction participants to mutually offset their differences when implementing projects. This paper has investigated and introduced the incentives of partnering from Vietnam perspective in terms of foreign and local participants perceptions. It has been shown that 'to learn mutually among participants' and 'to increase bidding advantages' are the most important incentives according to foreign and local practitioners respectively.

In this study, we propose an efficient expert system (ES) construction mechanism by using dynamic knowledge map (DKM) and database management systems (DBMS). Generally, traditional ES and ES developing tools has some limitations such as, 1) a lot of time to extend the knowledge base (KB), 2) too difficult to change the inference path, 3) inflexible use of inference functions and operators. First, to overcome these limitations, we use DKM in extracting the complex relationships and causal rules from human expert and other knowledge resources. Then, elation database (RDB) and its management systems will help to transform the relationships from diagram to relational table. Therefore, our mechanism can help the ES or KBS (Knowledge-Based Systems) developers in several ways efficiently. In the experiment section, we used medical data to show the efficiency of our mechanism. Experimental results with various disease show that the mechanism is superior in terms of extension ability and flexible inference.
