Let R be a prime ring with center Z and characteristic different from two, U a nonzero Lie ideal of R such that $u^2{\in}U$ for all $u{\in}U$ and $d$ be a nonzero (${\sigma}$, ${\tau}$)-derivation of R. We prove the following results: (i) If $[d(u),u]_{{\sigma},{\tau}}$ = 0 or $[d(u),u]_{{\sigma},{\tau}}{\in}C_{{\sigma},{\tau}}$ for all $u{\in}U$, then $U{\subseteq}Z$. (ii) If $a{\in}R$ and $[d(u),a]_{{\sigma},{\tau}}$ = 0 for all $u{\in}U$, then $U{\subseteq}Z$ or $a{\in}Z$. (iii) If $d([u,v])={\pm}[u,v]_{{\sigma},{\tau}}$ for all $u{\in}U$, then $U{\subseteq}Z$.

A Science Camp Program was developed and applied as an intensified course for gifted students. The implications for the development and implementation of out-of-school science activities were also deduced through the analysis of the preliminary application results. The key point of the science camp program is to boost students' science inquiry skills through self-directed activities. Several positive effects in terms of interest and participation in the program were observed and some implications were derived as follows; (1) The program should provide the students with more opportunities for discussion and debate in group activities. (2) The tasks need be divided into two parts; basic tasks and optional tasks in order to ensure that the students engage in fewer tasks more intensively. (3) Each activity needs sufficient orientation taking consideration of the possibility that not all students may be ready for the inquiry. (4) The use of real examples of scientific research processes can help the students develop open inquiry skills and problem posing skills.

This research examines the views of teachers and parents of special schools in Saudi Arabia, exploring the schools' strengths and disadvantages, as well as their impact on teachers, parents, and students with disabilities. The respondents' key views of the schools are identified, including the areas of consensus and conflict, and recommendations are made for the future, based on the findings. This research concerns a specific special education school in Saudi Arabia, and focuses on the understanding of special education in the country. The approach to the study is targeted and qualitative, with the six participants, three teachers and three parents, intentionally selected. The data collection is conducted via semi-structured interviews that explore the participants' views of special education in Saudi Arabia. A number of issues emerge from the results, and one raised by all three teachers is the need to improve school facilities. Although all three parents report that their children clearly benefited from attending a special school, two felt that the offering was insufficient, in terms of the teaching methods, and of supporting cognitive skills.

The survey is intended to improve science education by the analysis of problems produced in the following nine aspects (objectives, contents, materials, inquring methods, teaching methods, teachers, children, evalutions, admininative supports) during the past five years often the revision of new science curriculum. 1. View for science education. 1) The teacher's and children's view for science education can be seen renewed, being different from the old one. 2) Inquring method in learning and teaching began to take firm root and children came to know that it is the only way to study science. 3) Writers think that the new science education has stepped into the stage of being fixed to a considerable degree. 2. The aspect of administrative policy. 1) The amount of materials in possession is small and the present materials are lacking in solidity and precision. 2) Class room teacher's over load with miscellaneous things is a difficult problem to solve. 3) The shortage of the printed materials and books for children and teachers has an influence on the development of inquring method. 4) It causes cramming to examine all children at the same time by paper test. 5) It is more desirable to appoint qualified teacher only for science teaching. 3. Contents of science curriculum. 1) In current science textbooks. There can be found some contents which are difficult for teachers to understand and not in accordance with the reality of Korea. Therefore, it is imperative that contents of science textbooks should be reexamined. 2) As it is hard to teach concepts of reciprocal action and to prepare materials with teaching of the system of biological concepts, the teaching of contents is likely to be a cramming. 4. The aspect of in-service education. 1) It is obsolutely predominant reation that in-service education is making a great contribution to class room teaching. 2) As adiministrators' policy for science education has a great effect, in-service education for their enlightenment is needed.

This study reviewed and discussed the nature of scientific hypothesis described in philosophy, the philosophy of science, science, and science education. In these descriptions, a hypothesis was defined as one of five types: hypothesis as an assumption, hypothesis as a prediction, hypothesis as a tentative explanation, hypothesis as a tentative law, and hypothesis as a tentative causal explanation. Most scholars agreed that a hypothesis is a proposition or a set of propositions proposed as an explanation for an observed situation. In this view, a hypothesis is a possible answer to or an explanation of a question that accounts for all the observed facts. Also, it is a statement that explains why things happen in nature or an explanation for an observation that can be tested. In the five types of hypothesis meanings, a tentative explanation includes a tentative law and a tentative causal explanation. However, tentative laws are not explanation but description which are general statements drawn from specific experiences by way of a process known as induction. A number of studies also have distinguished hypothesis from assumption, tentative explanation, tentative law, and prediction. Therefore, a hypothesis is concluded to be a proposition or a set of propositions proposed as a tentative causal explanation for an observed situation.

The purpose of this research is to find out the change in graduate students' perceptions before and after they take a class on qualitative research. The class on qualitative research was held by the researcher in the winter semester of 2009. The subjects are nine graduate students (two male and eight female) and all elementary school teachers. An open-ended questionnaire with 5 items was used. The responses were interpreted, analyzed and categorized into several main conceptions. The results are as follow: First, some students perceived qualitative research as the counterpart for quantitative research, some perceived that qualitative research supplements quantitative research, while the rest of them had no concept of either before they took the class. Second, they all agreed that qualitative research is necessary in gifted education after they took the class. In order to better understand what is happening in classrooms, in terms of gifted education, a well organized curriculum for gifted education should be developed and conducted in graduate schools.

Most schools and educational institutions, as well as most companies, show willingness to teach CPR. However, as an essential element for the health care workers, this study aims to analyze the appropriate timing of education and improvements to the education, focusing on those who have trained for CPR. The survey was conducted for only those who applied for CPR education regardless of their profession in medical institutions. There were 105 males and 93 females by gender, and an average of 198 females were 33.5 years. The difference in CPR education depending on individual characteristics showed a high demand that all research subjects' gender, age and marital status should be improved to a practical education. During the education period, the efficiency of CPR was high. It is expected that the education of CPR will be used for the improvement of the training cycle and the training content since it is the enhancement of the performance capabilities that require practical application.
