Given the global impact of the AIDS pandemic, it is necessary to take every measure to prevent an epidemic of this disease in Korea. The only available strategy is prevention. Considering college students as a potential risk group, this study examined their knowledge of, and attitudes toward AIDS. In this study, a self-report questionnaire was administered to 167 students from three colleges in Taegu and Kyungbook province area. Findings indicated that most of the students had lacked knowledge about the AIDS. While knowledge about the modes of transmission and prevention improved, some respondents still believed that AIDS could be transmitted by sharing cups (17.4%), by coughing or sneezing(29.3%), and by moskito (25.7%). About 10% of the students reported that they had received some instruction about AIDS, and 87.3% indicated a desire to know more about the disease. Most of the students reported that they obtained AIDS information from media devices such as TV and newspaper. To the questions designed to examine attitude towards AIDS patients, the students showed a tendency to view AIDS patients as responsible for their own illness (85.6%). Interestingly, they showed sympathy to their imaginary friends and relatives suffering from AIDS (78.4%-90.2%). Eighty percercent of the respondents felt that they personally were not at risk. The study findings suggest a need for the development of AIDS educational programs for college students.

The primary purpose of this study is to identify the educational contents of the research paper writing program. In addition, this searches for the appropriate application method as information literacy instructional course. For clarifying and supporting the purpose, this study analyzes the expository texts with the seven kinds of published references book on research paper writing program. As the results of examination, the study reveals that they are made up with seven important contents. Evidently, this analysis makes up for the information literacy strategy to intensify the information literacy instructional course. Convincingly, we propose the educational contents which contain ideas of 'making research plan,' 'managing information,' and 'writing essay' in order to optimize for the current school library environment.

Purpose: This study was conducted to develop a Web-based learning program on cardiopulmonary emergency care for clinical nurses and to evaluate learners' responses. Methods: Based on the assessment of learning needs of clinical nurses, a total of three self-directed learning modules were developed according to the procedure of the ADDIE (assessment, design, development, implementation, & evaluation) model. Results: Each learning module included the emergency treatments and drugs used in the real patients' situations with cardiopulmonary crisis, which had been adopted from the emergency department of a C University hospital located in G-city. Real video clips for endotracheal intubation and ACLS (advanced cardiac life support) were developed with the help of the staff of the department of emergency medicine using a human simulator, $SimMan^{(R)}$. The program published on the Web was evaluated by 20 clinical nurses who are working in the emergency department and wards of a C-University hospital. About 80% of the respondents were satisfied with the program contents, design, and learning strategy. Conclusions: Web-based learning programs on cardiopulmonary emergency care are needed for clinical nurses as educational material for staff education to increase their knowledge for making immediate clinical decisions and in giving skilled care in emergency situations.

Web-based instructional system gives us the greatest potential for supporting face-to-face classroom instruction in many ways. With the help of the Web in high school setting, all of the participants including teachers can share many different experiences, active interactions, and even learning outcomes. In this paper, web-based instructional strategy based on constructivism for extending the geographical thought is suggested. The results from the formative assessment, as well as the statistical results from regression analysis concerning the learners' satisfaction, are also provided.

For real-time systems it is important to obtain the accurate worst-case execution time (WCET). Furthermore, how to improve the WCET of applications that run on multicore processors is both significant and challenging as the WCET can be largely affected by the possible inter-core interferences in shared resources such as the shared L2 cache. In order to solve this problem, we propose an innovative approach that adopts a code positioning method to reduce the inter-core L2 cache interferences between the different real-time threads that adaptively run in a multi-core processor by using different strategies. The worst-case-oriented strategy is designed to decrease the worst-case WCET among these threads to as low as possible. The other two strategies aim at reducing the WCET of each thread to almost equal percentage or amount. Our experiments indicate that the proposed multicore-aware code positioning approaches, not only improve the worst-case performance of the real-time threads but also make good tradeoffs between efficiency and fairness for threads that run on multicore platforms.

The purpose of this study was to investigate the relation between the levels of cognitive conflict and students' conceptual change. In this study, 30 Korean high school students were selected from 450 10th graders by examining the pretest results. Two different strategies were used to induce cognitive conflicts in students, an anomalous or conflict situations; demonstrations and logical arguments against students' preconception. After arousing the students' cognitive conflict, the level of cognitive conflict was rated. Pretest, post-test and delayed post-test were administered to check the conceptual change. The tests consisted of 5 items in mechanics and electricity, respectively. Therefore, the demonstration method showed effective conceptual change, more than the logical argument method did. Students changed their conceptions more easily and frequently in the area of mechanics than in electricity. Students who showed higher levels of cognitive conflict indicated more positive conceptual change than those who showed lower conflict levels. 59 cases (56%) out of 105 who experienced high levels of cognitive conflict were changed into scientific conceptions one month later; however only 16 cases (35%) out of 46 who experienced low levels of cognitive conflict changed into scientific conceptions. Students who experienced higher levels of cognitive conflict showed higher rates of conceptual change. It could be concluded that designing instruction to induce cognitive conflict is a useful strategy to promote conceptual change.

The purpose of this study was to analyze middle school students' problem posing types and strategies. we analyzed problems posed by 120 middle school students during mathematics class focused on problem posing activities in various aspects. Students' posed problems were classified into five types: not a problem(NP), non-math(NM), impossible(IM), insufficient(IN), sufficient(SU) and each of the posed problems. Students used three kinds of problem posing strategies such as goal manipulation(GM), assumption manipulation(AM), and condition manipulation(CM), and in posing one problem, one or more than two strategies were used. According to the prior studies, problem posing can contributes to the development of students' problem solving ability, creativity, mathematical aptitude, and a broader understanding of mathematical concepts. However, we found that some students had difficulties in posing problems or limited understandings of that. We hope the results of the study contribute to encouraging problem posing activities in mathematics instruction.

The purpose of this study was to examine the questioning styles of $3rd{\sim}6th$ elementary science textbooks in terms of frequency, type, and placement of questions. This paper also sought to analyse and compare the kinds of scientific inquiry processes elicited by the questions in the content domains of textbooks. The instrument used was the Textbook Questioning Strategies Assessment Instrument (TQSAI). The average number of questions per book was 129 and the ratio of questions to sentences was 31.9%. The results were summarized as followings. First, many science textbook questions were used for the purposes of explanation or identifying levels of teaming. Second, process skills were located in each content domain, although it was not affected meaningfully. Third, the number of text question was below 3 in each elementary science class. Therefore, an effective questioning development framework is clearly needed for elementary science instruction.

The purpose of the study was to investigate the effects of the use of RNP curriculum based on Lesh translation model on third grade students' understandings of fraction concepts and problem solving ability. Students' conceptual understandings of fractions and problem solving ability were improved by the use of the curriculum. Various manipulative experiences and translation processes between and among representations facilitated students' conceptual understandings of fractions and contributed to the development of problem solving strategies. Expecially, in problem situations including fraction ordering which was not covered during the study, mental images of fractions constructed by the experiences with manipulatives played a central role as a problem solving strategy.

Delays in completing construction projects have significant financial and social impact to all parties involved in the construction process and in particular in developing countries. This is very evident in most construction projects in Libya and in both public and private sectors. The research study was initiated by Libyan Government and the main aim of the project is to develop a new strategy in reducing the impact of delay factors. In order to achieve this, a number of objectives have been set-to conduct a comprehensive literature survey, to conduct a comparative study of the delay factors in project completion in both Libya and UK using semi structured questionnaire and finally, to identify and analyse the causes of delay and ranked them using frequency of occurrence and severity. The critical causes of delay for construction projects were quite different between Libya and UK. For the former, the most critical causes of delay in Libyan construction industry were low skills of manpower, changes in the scope of the project, slowness in giving instruction and poor qualification of consultant, while for the latter they were financial problems, bad weather conditions on the job site and change in the scope of project. Statistical experiments including Paired Samples T-Test, was run to test the significance of the survey data in both countries Libya and UK. The statistical results confirmed the collected data from the survey were significant.
