This study reports on the use of the trait and state cognitive/metacognitive strategy use and the difference of the trait/state strategy use according to students' proficiency level. First of all, for checking up the trait strategy use, 119 first-grade male students in a high school completed the questionnaire on strategies which they thought they used during a reading test. Secondly, to find out their state strategy use, students took a fifteen-item reading comprehension test, followed by filling out questionnaires on cognitive and metacognitive strategies used in the test. This study employed quantitative data analysis. The results suggested that (1) the cognitive and metacognitive strategy use in the trait and state conditions are used the most by the high proficiency group and they are correlated respectively; (2) these strategies are used with statistically significant difference according to students' proficiency level, especially to the lower level students. The highly successful group uses the cognitive and metacognitive strategy in the actual test situation more than the lower proficient group; there is no difference in trait and state strategy use.

본 연구는 약형 EMH에 대한 반론으로 제기되어 왔던 모멘텀전략과 반대전략의 우월성에 대하여 검정하였다. 모멘텀전략과 반대전략이 우월한 전략이라면 이는 약형 EMH에 대한 중대한 비판이 된다. 하지만 몬테카를로 시뮬레이션 결과에 따르면 기존의 검정방법은 유의수준왜곡이라는 오류를 갖고 있는 것으로 나타났다. 이에 본 연구는 데이터 스누핑 편의를 해결하는 것으로 알려진 White (2000)의 사실성 체크검정을 이용하여 모멘텀전략과 반대전략의 우월성을 검정하였다. 검정결과는 다음과 같다. 종합주가지수에 대한 정액정기매입전략을 벤치마크 포트폴리오로 정하였을 때 평균수익률을 이용하면 모멘텀전략 중 최선의 전략은 벤치마크 포트폴리오보다 우월한 것으로 나타났다. 하지만 위험을 고려한 성과측정치인 샤프비율을 이용할 경우 모멘텀전략과 반대전략 중 최선의 전략은 우월한 전략이라고 볼 수 없었다. 따라서 위험을 고려한다면 모멘텀전략과 반대전략의 우월성을 근거로 약형 EMH를 기각할 수는 없다.

This study was conducted to develop and effective strategy for environmental education. At first, the environmental education strategy through personalization of environment was proposed. Then students in a middle school participated the program according to the strategy and its. effect was investigated. The strategy was designed in basis of the role of the limbic system in brain and involved field-oriented experience such as viewing the non-personal environment as the personal environment. Gokneung stream was selected as the site to conduct this environmental education. Students investigated water quality by senses and biological method. The same content was taught for the classroom group and simple outdoor group selected for the comparison by traditional instructional method. The pre- and post-test by the instrument to test environmental attitude, qualitative questionnaire, cognitive test, the pre- and post-interview were conducted to investigate the effect the program. The achievement of the classroom group(personalization group). But the change of the attitude toward environment of personalization group between pre- and post-test was significantly higher than the classroom group. In qualitative questionnaire and pre- and post-interviews, attitude toward environment differed between two group. The behavioral change to discover and to solve environmental problems was demonstrated in case the personalization group, but was unclear in the classroom group. These results indicated the environmental education strategy through personalization of environment was an effective strategy to change the awareness, attitude and behavior toward the environment compared with a traditional teaching strategy.

Test methodology is diversity by devices and the number of test pattern is tremendous because the digital circuit includes TTL and CMOS family ICs as well as high density devices such as ROM and RAM. Accordingly, the quick and effective test strategy is required to enhance the test productivity. This paper proposes the test strategy which is able to be applied efficiently to the diversity devices on the digital circuit board by analyzing the structure and characteristic of the digital device. Especially, this test strategy detects the faulted digital device or the faulted digital circuit on the digital board using SSA(Serial Signature Analysis) technique based on the polynomial division theory The SSA technique identifies the faults by comparing the reminder from good device with reminder from the tested device. At this time, the reminder is obtained by enforcing the data stream obtained from output pins of the tested device on the LFSR(Linear Feedback Shift Register) representing the characteristic equation. Also, the method to obtain the optimal signature analysis circuit is explained by furnishing the short bit input streams to the long bit input streams to the LFSR having 8, 12, 16, 20bit input/output pins and by analyzing the occurring probability of error which is impossible to detect. Finally, the effectiveness of the proposed test strategy is verified by simulating the stuck at 1 errors or stuck at 0 errors for several devices on typical 8051 digital board.

A test plan is a high level document detailing objectives, processes, schedules and so on for verifying a developed software. And a test strategy, a component of a test plan, is about how to test software products to guarantee its quality and find bugs in the software in advance. Therefore, establishing effective and suitable test strategies is important for elaborating test processes. However, these tasks are difficult for project managers who write a test plan if they were not trained well in software test processes. And mis-designed test strategies will also mislead entire testing behaviors that testers would do. As a result, there would be a low quality software product in the end. To solve this problem, we propose a new test strategy reuse technique in this paper. By utilizing test plans of already completed software development projects, we lead test planer to reuse suitable and effective test strategies which were used in previous projects. To do so, we evaluate existing test strategies by utilizing ISO/IEC 25010 quality model for evaluating the suitability of test strategies and also use effectiveness metrics for test strategies. And from these evaluations, we predict completeness of new test plan that is written by reused test strategies. It can help the project manager to write an appropriate test plan for the quality characteristics which are selected as objectives for testing and software product. We show the possibility of our approach by implementing a prototype into the existing framework in a case study.

The SSA technique in the digital circuit test is required to be repeated the input pattern stream to n bits output nodes n times in case of using a multiplexor. Because the method adopting a parallel/serial bit convertor to remove this inefficiency has disadvantage of requiring the test time n times for a pattern, the test strategy is required, which can enhance the test productivity by reducing the test time based on simplified fault detection mechanism. Accordingly, this paper proposes a test strategy which enhances the test productivity and efficiency by appling PAS (Parallel Signature Analysis) technique to those after analyzing the structure and characteristics of the digital devices including TTL and CMOS family ICs as well as ROM and RAM. The PSA technique identifies the faults by comparing the reminder from good device with reminder from the tested device. At this time, the reminder is obtained by enforcing the data stream obtained from output pins of the tested device on the LFSR(Linear Feedback Shift Resister) representing the characteristic equation. Also, the method to obtain the optimal signature analyzer is explained by furnishing the short bit input streams to the long bit input streams to the LFSR having 8, 12, 16, 20bit input/output pins and by analyzing the occurring probability of error which is impossible to detect. Finally, the effectiveness of the proposed test strategy is verified by simulating the stuck at 1 errors or stuck at 0 errors for several devices on typical 8051 digital board.
