Value prediction of instruction issue width in superscalar processor is a technique to obtain performance gains by supplying earlier source values of its data dependent instructions using predicted value of a instruction. In this paper, the mean performance improvement by predictor as well as prediction accuracy and prediction rate are moaned and assessed by comparison and analysis of value predictor that instruction issue width(4,8,16) in parallel and run by predicting value, which is for performance improvements of ILP[4]. The experiment result show the superiority hight performance of 8-issue.

This paper proposed an application of agile management method to resolve the electrical system issues identified during the mass production phase of aged aircraft performance improvement. The proposed method was applied from issue analysis to on-site verification and testing stage, before the formal configuration control process. At this time, the project was carried out by setting a sprint period to complete the verification according to requirements through daily scrum and sprint review. As a result, It was verified that the wiring installation of the aircraft, which was the output of the sprint, met requirements within the defined sprint period.

Purpose: This study aimed to develop an educational program on nursing records especially focused on legal issues, and to test the effects of the educational program on nurses' knowledge, performance, and behavior. Methods: A textbook on legal issue-focused nursing records and an instrument with 36 items rated on a 5-point scale (1-5) for measuring the nurses' charting-related performance and behavior were developed from November 2007 through March 2008. A nonequivalent control group pretest-posttest design was employed to test the effects of the education program. Knowledge was self-reported by the Nurse Charting Knowledge Scale, while performance and behavior were measured by their nurse managers. The pretest and posttest were conducted from March through May in 2008. A total of 226 Korean nurses participated in this study. Data were analyzed with descriptive statistics, t-test, Chi-square, paired t-test, Spearman's coefficient, and multiple regression. Results: Nurses who received the intervention showed greater levels of knowledge (t=10.28, p<.001), performance (t=2.53, p=.013), and behavior scores (t=3.07, p=.002) than those of the control group. The factors influencing the improvement of knowledge were 'job attitude' (t=-3.32, p=.001) and 'career in present unit' (t=2.95, p=.004). The factor influencing the improvement of performance was 'career in present unit' (t=-3.39, p=.001). The factor influencing the improvement of behavior was 'job attitude' (t=-3.46, p=.001). Conclusion: The educational program on legal issue-focused nursing records was effective in improving nurse charting-related knowledge, performance, and behavior.

This paper grasped the labor productivity actual condition by the standard of per unit working hour and production about the main products of our country's industrial the main materials and could understand the average of our country's labor productivity as compared this with the labor productivity actual condition of Japan. As the point at issue of analitical result. 1. Low a matter of thinking about productivity. 2. Have a lot of difficult problem in an industrial part. 3. Have the point at issue on technical development and accumulation. 4. Have the point at issue on management. As a countermeasure about these. 1. must convert the way of use of industrial policy. 2. must make a housing development and special serialization of a small and medium enterprise. 3. must establish an organic technical development system. 4. must grope the policy of management rationalization.

One of the hot issues on GNSS might be that China declared to broadcast the signal of the new Global Navigation Satellite System called Beidou-Compass in December 2011. The multi-GNSS systems with the existing GPS and GLONASS consist of more than 100 GNSS satellites and transmit their signals in near future. Many benefits are expected in accuracy, availability, integrity and increasing anti-jam performance. In this presentation, we have mainly investigated the latest issue for multi- GNSS and discussed spectrum analysis as well as the accuracy improvement issue. The use of the modern weapon system based on satellite navigation information was also briefly investigated in warfare.

This study investigated the effect of the environmental issue analysis instruction on the decision making ability of middle school students. A pretest-posttest control group design was employed. The participants for the research were 288 1st grade male students in middle school in Seoul, the environmental issue analysis lesson group consisted of 142 members and the non-environmental education group consisted of 146 members. The cognitive level of the students were divided into three groups-concrete, transition, formal-as the result of GALT test. Students take issue analysis lessons during 6 weeks, one lesson per a week. Students had studied through worksheets reconstructed and developed by researcher on basis of issue analysis suggested by Ramsey et al. (1997). The results of the research were followings: After lesson for environmental issue analysis, all of the students were improved in decision-making ability regardless of cognitive level (p<.05). Especially, decision-making ability of the transition group students was improved to a high degree. Scores of searching relevant information, generation of alternatives, identification of values for selection criteria, the evaluation of alternatives' merits and demerits, prediction of consequence were increased in experimental group (p<.05). But the ability of selection of alternatives according to value was not reached statistically meaningful improvement. The decision-making ability of the control group students was not improved but ability of selection of alternatives, the evaluation of consequence were increased (p<.05).

The reliability is the critical issue in many computer applications, particularly in process control system. In this paper we describe how to achieve the reliability improvement in controller system based multiprocessor. The proposed method is accomplished by using the techniques of fault detection, fault isolation, safe action, and fault diagnosis.

The large surface micro machining system includes the equipments and processes for manufacturing the ultra precision micro patterned products with large surface through the mechanical machining. Recent major issue on the micro machining technology may be the development of optical parts for the back light unit of display which has the largest market. This special issue makes up with three parts; the large surface micro machining system and machine, machining process and forming process. In this paper, the state-of-the-art and core technology of large surface micro machining system is introduced with focus on the manufacturing technology for the back light unit of LCD TV. Then, some research results on the development of a roll die lathe is introduced which involves the concept of machine design, improvement of thermal characteristics in the spindle system, improvement of relative parallelism and straightness between spindle system and long stroke feed table, machining of micro pitch patterns. Finally, the direct forming process is introduced as the future work in the large surface micro machining field.

Objectives : Motivational factor is a unique contributor to the typically poor academic performance of children with ADHD. However, few study has directly intervened learning motivation in children with ADHD. We conducted this study to explore the direct effects of the learning motivation improvement program applied to children with ADHD. Method The program was designed in order to increase an interest-inducing educational intervention, an academic skills integration, a basic learning activity (reading, writing, and math), and children's self-esteem. We conducted the program twice a week (total 10 sessions) and assessed learning motivation, teaming attitude, self-esteem, academic performance, and problem behaviors of participating children. Results : After the program, teachers reported improvement in teaming motivation. In addition, parents notified sisnificant reduction of problem behaviors. Children reported improvement in a few domains of teaming motivation and learning attitude. Conclusion : While loaming motivation is regarded as an important factor in education, there have been few studies considering this issue in both educational and psychiatric fields. The teaming motivation improvement would be needed in both field in order to reduce the deficits in academic performance in children with ADHD.
