  • The study conducted a survey on mathematics teachers' perception about the mathematics curriculum and carried out a field survey of schools' compliance of the 2009 revised mathematics curriculum. The questionnaires were distributed to and collected from 36 mathematics teachers in 22 middle and high schools. According to the results of the study, it was found that most mathematics teachers had low interest in and did not feel the necessity and importance of revising the mathematic curriculum. This was because that the necessity and direction of the curriculum revision was not well understood by secondary school teachers, thanks to a hasty revamping. In addition, schools are organizing and operating their own educational programs with the focus on the college entrance exams, regardless of the guidelines of the current revised curriculum.

  • This paper presents a development of operation scheduling and reactive operation scheduling system for hull fabrication. The methodology for implementing operation scheduling system is HHGA(Hierarchical Hybrid Genetic Algorithm) which exploits both the global perspective of the genetic algorithm and the rapid convergence of the heuristic search for operation scheduling. The methodology for the reactive operation scheduling is the revised HHGA which consists of manual schedule editor for occurrence of exceptional events and the revised scheduling method used in operation scheduling. As the results of experiment, it has been confirmed that HHGA is able to search good operation scheduling within reasonable time, and the revised HHGA is able to search load-balanced reactive operation scheduling with minimum changes of initial operation schedule within short period of time.

  • Side channel spillways based on Hinds theory were tested. Surface water level at the beginning point of side channel is the same as the crest level of weir in the usual design. Here, side channel section were moved upwards $\frac{1}{2}$ of the total head on the crest and test(revised experiment) were made. In the revised experiments, coefficients of discharge for design flood (Q) were the same with that of original design experiments. In case of 1.2Q a little influence of submergence were appeared, coefficients of discharge were decreased to be about 97.6% of that of original design experiments, therefore, Reservoir flood water level become higher about 2-3cm than original case. So revised design can be used for actual purpose and it will brings much savings in construction cost of side channel spillway.

  • Recently, multiple criteria decision making has been well established as a practical approach to seek a satisfactory solution to a decision making problem. Goal programming is one of the most powerful MCDM tools with satisfying operational assumptions that reflect the actual decision making process in real-world situations. In this paper we propose an efficient method implemented on a microcomputer for solving linear goal programming problems. It is an iterative revised goal simplex method using the sparsity technique. We design as interactive software package for microcomputers based on this method. From some computational experiences, we can state that the revised iterative goal simplex method using the sparsity technique is the most efficient one for microcomputer for solving goal programming problems.

  • This paper presents an application to a multimachine power system of power system stabilizer using revised pole shift adaptive algorithm. Controller parameters are determined by using adaptive control theory in order to maintain optimal operation of generator under the various operating conditions. To determine the optimal parameters of controller and overcome the problem of pole placement algorithm, this paper presents pole shift algorithm revised pole shift factor. Also, the difference between the speed deviation with weighted factor and voltage deviation is used as the input signal of adaptive controller, which provides good damping characteristics. The results tested on a multimachine power system verify that the proposed controller has better dynamic and transient performance than conventional controller.

  • The main objective of this study is to explore the relationship between psychological factors (i.e. math anxiety, attention, attitude, Working Memory Capacity (WMC), and Field dependency) and students' mathematics problem solving based on Revised Bloom Taxonomy. A sample of 169 K11 school girls were tested on (1) The Witkin's cognitive style (Group Embedded Figure Test). (2) Digit Span Backwards Test. (3) Mathematics Anxiety Rating Scale (MARS). (4) Modified Fennema-Sherman Attitude Scales. (5) Mathematics Attention Test (MAT), and (6) Mathematics questions based on Revised Bloom Taxonomy (RBT). Results obtained indicate that the effect of these items on students mathematical problem solving is different in each cognitive process and level of knowledge dimension.

  • China had revised Foreign Trade Law in order to fulfill its WTO commitments and duties, and fully exercise its rights and benefits as a WTO member. The main contents of the revised Foreign Trade Law as followed. For the first time, individuals are allowed to conduct foreign trade. Intellectual property is an important component of foreign trade, and protecting intellectual property rights is a key issue. A chapter on Intellectual property protection is one of the major additions to the Foreign Trade Law. New sections have also been added to allow and provide guidance for conducting investigations and seeking relief. Finally, the new law beefs up and clarifies enforcement procedures. It regulates the setting up of early warning and emergency systems and a foreign trade statistics system.

  • Demands on a quiet environment is increasing because of noisiness and annoyance due to the extended use of noisy electronic device. Determination of sound power levels of noise sources using sound pressure in a reverberation room is usually a relevant method for devices with comparatively large volume or unevenly distributed source position. This study aims to observe the contents of ISO 3741 and analyze its changes in the revised standard ISO 3741-1999. And also aims to assess the revised ISO 1999 its effectiveness and limitations with an actual application to measure the sound power level of a refrigerator.

  • This paper investigates what are the types and legal grounds for interim measures in the U.S. arbitration practices. The statutory ground for the interim measures is the Revised Uniform Arbitration Act. Another ground, probably the most important, is the parties' own intentions to adopt the interim measures in their arbitration proceeding. Most typical interim measures in arbitration include preliminary injuction, attachment and antisuit injunction. In the U.S ex parte motion for interim measure is rarely allowed while the Revised UNCITRAL Model Law specified an ex parte interim measure. In launching the interim measures, the US courts have demanded several requirements including imparability, probability of success and passing of the balance test. In general, the U.S. courts have properly interfered with the procedural issues in arbitration unreined but leaving the substantive issues untouched. It is believed that such interference has helped to enhance the credibility in arbitration with respect to fairness and justice.

  • The Revised Classroom Play(RCP) scale was validated for Korean 4th grade students. 104 boys and 80 girls took the translated RCP. Test-retest reliability was established with 41 children after 2 months, and test of criterion-related validation was established by the Social Behavior Scale administered to 71 children. All raw scores were standardized by classroom and sex to adjust for differences in the number of nominators and nominatees. The structure of the RCP resulted in 3 factors, 'sociability-disruptive' and 'shy-isolated', with 28 items similar to the original RCP 3 factors. For criterion-related validity, the correlations between the 3 factors of the RCP and the 3 factors of the Social Behavior Scale were positive. For internal consistencies, Cronbach's ${\alpha}$ of the RCP factors ranged from .77 to .94. Test-retest reliability coefficients ranged from .33 to .51. Analyses of variance revealed good item discrepancies for all 28 items. These results confirm the RCP as a valid and reliable measure of the quality of peer relations.
