This study performs the subjective evaluations of LED illumination conditions according to three types of color temperatures (7,000[K], 5,000[K], 3,000[K]) after employing LED illumination system in the classroom, Since the objective of this study is to develop an artificial lighting conditions like day light comfortable to students in the classroom, the learning effect based on three types of LED illumination conditions are analyzed. Three factors (learning intention, learning environment, learning motivation) are extracted by ANOVA and there are preference differences of LED illumination conditions between learning intention and learning environment factors. Especially, preference differences of LED illumination conditions are existed about calculation, reading and fatigue reduction. The test results of this study can be applied to obtaining high achievement of learning based on the lighting conditions.

현재까지 연구된 SRGM을 이용하여 정해진 시각에 수집된 테스트 데이터를 가지고 예상되는 소프트웨어 고장이나 잔존 에러수를 추정할 수 있다. 그러므로 소프트웨어 신뢰성 달성 정도 및 운용 단계에서 소프트웨어 신뢰도를 예측할 수 있다. 그러나 어느 모델을 선택하는가에 따라 신뢰도 평가는 달라질 수 있다. 그러므로 본 연구에서는 에러제거 비용을 고려한 SRGM으로서 테스트 비용을 에러 검출 및 에러제거 비용까지도 고려한 SRGM을 제시하고자 한다. 또한 이를 이용하여 소프트웨어에 있는 잔존 에러수와 릴리즈 이후 신뢰도 값과 최적 릴리즈 시기를 추정하여 보다 더 정확한 신뢰성 평가를 할 수 있다.

For the purpose of diagnosing the problems in inquiry instruction and evaluation in secondary schools of Korea, an inquiry achievement test and a questionnaire were administered to a sample of 127 science teachers and 610 junior high school students. The analysis of the results served to the clarification of broo:J. range of problems concerning inquiry teaching. Based on the data gathered and analyzed in this study, the major suggestions are as follows. 1. The content of science textbooks must be diminished, and be written for easier understanding. 2. Science instruction and entrance exams must be changed from content-oriented to inquiry-oriented. 3. Effective teacher education program regarding inquiry teaching and evaluating method must be developed and performed.

This study is about the influence of recording reflective journals and receiving feedback from professors on academic achievements in technical writing. We analyzed the differences between the test group who had recorded reflective journals and getting feedback, and the control group who had gotten feedback without reflective journals. And we compared academic achievements by conducting both professor evaluation and peer evaluation in technical writing. The results showed better learning effect, learning satisfaction and academic achievements in the test group than the other.

The Inquiry Activities the newly developed Korean High Schol Biology Textbooks were evaluated using SIEI(Seientific Inquiry Evaluation Inventory). The textbook evaluated are five Introductory Biology books and five Advanced Biology books developed in 1990. The instrument, SIEI, was developed by Myung Hur in his doctoral study at Columbia University in 1984. The major findings of the study are summarized below. 1. The inquiry activities in the textbooks are focusing on the low level science process skills 2. Students are rarely asked to formulate a hypothesis or to design an experiment. 3. The structure of the Inguiry Activities are mostly competitive, thus inhibiting the inquiry achievement of students. 4. The Inquiry Indices of the textbooks are between 14 and 16, meaning only 14 to 16 percent of the total instructional time are to be devoted to inquiry activities.

This paper is concerned with education courses operating practices for basic computer literacy training. In this study, we propose an example for students to effectively measure and evaluate the achievement of defined ability in the performance measurement and analysis, learning objectives and learning outcomes set in operation throughout the course. Through research and development use case presents the tools for teaching method and effective and objective measurement of the related subjects. And based on the results, we propose the possibility of utilizing NCS-based course operation and education certification. In this study, the measurement process is based on the association with the objective of the development and operation, and measurement tools, measuring tools for measuring learning outcomes associated with the curriculum design methods for the measurement and evaluation of the case of the operation of the course units of learning outcomes and the method proposed.

It is difficult to develop objective evaluation techniques for the productivity in an R&D organization because there exists such as time lag between inputs and outputs, difficulties of measuring the influencing factors and results of a research and of comparing R&Ds with other objects towards innovation, and problems in identifying analysis elements. Particularly, governmental research institutes, pursuing publicity, have more difficulties in evaluating research achievement than the private ones. In evaluating the productivity of R&D organizations, this study aims at practically using the quantitative evaluation techniques by applying them to the public as well as private institutes. This will be finally contributing to decision making for effective management of R&D organization.

Capstone design is a subject taught in a setting where students gather in a team, decide on their own selected topic, and collaborate with one another to perform a project. A fair assessment is very important in a team project-based capstone design course for students. Many instructors agree that harmonizing creative evaluation and outcome assessment is hard in capstone design class. In also, it is not easy to assess students' individual efforts and achievements fairly in accordance with team-based assessment practices. To resolve this issue in this paper, we have surveyed various engineering design education methodologies, and have modelled existing evaluating elements into a modified creative process and outcome assessment framework for team project assessment. In particular, we focused on a method of fairly assigning credits by combining team based and individual-level assessments. Analyzing students' achievement and grade evaluation and verifying the validity of the proposed method was performed.

This paper analyses how technological capabilities and entrepreneurship of technology-based start-ups affect their performance. In this paper, a multiple regression analysis was conducted on 248 technology-based start-ups. The effects of indicators of technological capacity like R&D intensity, R&D organization, technology competitiveness, patents, and certification were analyzed. Factors affecting sales were R&D intensity and technological competitiveness. Technology competitiveness and patents were the significant factors influencing product competitiveness. The factor that positively influenced organizational performance, customer performance, and achievement of start-up goals was technological competitiveness. The results of such an analysis should be designed to discover and foster long-term innovation potential, rather than relying on short-term financial performance.

This study aimed to test method on the accuracy of estimating the items parameters and ability, using the Three Parameter Logistic. To achieve the objectives of the study, an achievement test in chemistry was constructed for third-year secondary school students in the course of "natural sciences". A descriptive approach was employed to conduct the study. The test was applied to a sample of (507) students of the third year of secondary school in the "Natural Sciences Course". The study's results revealed that the (EAP) method showed a higher degree of accuracy in the estimation of the difficulty parameter and the abilities of persons higher than the MML method. There were no statistically significant differences in the accuracy of the parameter estimation of discrimination and guessing regarding the difference of the two methods: (MML) and (EAP).
