Researchers and curricula continue to call for proof to serve a central role in learning of mathematics throughout kindergarten to grade 12 and beyond. Despite its prominence and recognition gained during past decades, proof is still a stumbling block for both teachers and students. Research efforts have been made to address issues related to teaching and learning of proof. An area in which such research efforts have been made is analysis of curriculum material (i.e. textbook analysis) with a focus on proof. This study is another research effort in this area of research through investigating the guidance offered in curriculum materials with the following research question: What is the nature (e.g., kinds of content knowledge, pedagogical content knowledge) of guidance is offered for teachers to implement proof tasks in grade 8 geometry textbooks? Results indicate that the guidance offered for proof tasks are concerned more with content knowledge about the content-specific instructional goals than with pedagogical content knowledge which supports teachers in preparing in-class interactions with students to teach proof.

The purpose of this study is to investigate the desirable method of courtesy education for middle school students. The major research questions of this study are to identify and test the follows： 1) The influence of the environment (grade, sex, the educational background of father, the educational background of mother, the scale of family, the presence of grandfather, the presence of grandmother, students’age ranking among their brothers and sisters, religion, academie record) on the middle school students’ knowledge and attitude on courtesy. 2) The influence of the courtesy education on students’knowledge and attitudes on courtesy. 3) The degree of change on their knowledge and attitudes after courtesy education. The response were given by 485 middle school students and their mothers in Wanju county Chonbuk province. Frequences, Percentages, Means and Standard Deviations were calculated, T-test and Pearson Correlation Coefficients were used for data analysis. The result of this study are as follows, 1. The influence of environment： 1) Higher grade students gained more score of courtesy test than lower grade ones. 2) Female students gained more score than male students. 3) The students who had higher academic record gained more score of courtesy test than any other students. 2. The influence of courtesy education： Most of educated groups changed significantly due to courtesy education. It showed that courtesy education contributed to improve their knowledge and attitudes on courtesy. 3. After courtesy education： On the one hand, the most changed attitude was bow-courtesy area and then good-manners area, conversation-courtesy area, etc. On the other hand, the basic spirit area on courtesy changed less than any other areas. It means that long-term courtesy education should be done in order to change students’ attitudes on courtesy basically, even though they could improve their knowledge and attitudes externally in a short time.

This study was conducted to identify adults' knowledge, attitude, dietary behavior, and lifestyle for cancer prevention, and to examine the relation between these variables. The participants were 414 adults in the Jeonbuk area. The data were analyzed using Pearson correlation coefficients, ANOVA and Duncan test with SPSS v. 12.0. The score for participants' knowledge about cancer was 23.98 points of a possible 30, the score for attitude towards cancer was 44.46 points of a possible 55, the score for preventive dietary behavior for cancer was 36.79 points of a possible 55, and their score for preventive lifestyle for cancer was 29.76 points of a possible 40. The knowledge, attitude towards cancer, dietary behavior, and lifestyle for cancer prevention showed significant differences according to the general characteristics (e.g., age, religion, monthly income, educational level, job, health condition, and interests). There was a significant positive correlation between knowledge about cancer, attitude towards cancer, dietary behavior, and lifestyle for cancer prevention. Dietary behavior for cancer prevention showed a positive correlation with lifestyle for cancer prevention. In conclusion, it is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive health behavior for cancer among adults.

The current exploratory study attempted to investigate the influence of environment-friendly agricultural products(EAPs) perception on EAPs consumption behavior. The survey was conducted to parents of elementary school in Chung-buk area by the help of homeroom teachers of each school. Out of 500 questionnaires administered, a total of 305 completed questionnaires were returned, yielding a response rate of 61%. Regarding buying behavior, 89.6% of respondents have ever bought EAPs, among them, 52.9% usually bought in a mart. The reason to buy EAPs was mostly safety(57.6%), nutrition & health(30.4%), and quality(7.0%). The 11 items representing the attitude and knowledge were analyzed, resulting in three distinct dimensions-'attitude', 'knowledge', and 'concern'. The knowledge level of EAPs was slightly higher than medium. Concerning the influence of EAPs perception on EAPs consumption behavior, the more having high knowledge and attitude level on EAPs, the more lead to the EAPs consumption behavior. This implicit the importance of education to enhance the knowledge level and positive attitude towards EAPs.

The study examined the perceived benefits and knowledge level of the mushroom farmers on mushroom production in selected local governments area of Oyo State, Nigeria. The data obtained were analyzed with frequency, percentage, mean and standard deviation. Multistage sampling procedure was used to select 143 respondents using questionnaire and interview schedule. From the result it was affirmed that the majority (63.0%) of the respondents were males, also about 81.8% of the farmers were married. Radio (96.5%) was the most common source of information available to farmers, seconded by family and friends 86.0%. Based on the distribution of the knowledge level of farmers in mushroom production (63.6%) of the farmers had highest knowledge in mushroom production with the mean score (9.28). Majority (64.3%) of the mushroom farmers perceived mushroom production to be of benefit to them, with the mean score (10.35). It was concluded that majority of the farmers that had knowledge of mushroom production needs training in some specific aspects of the production process. It is recommended that research institutes, extension agents and Non-governmental organizations needs to organize training to enlightened and provide necessary information needed to the farmers on mushroom production.

Purpose: The objective of this study was to evaluate the effects of a urinary incontinence management program for middle aged women living in a rural area. Method: The research design was a one-group pretest-posttest design. Forty eight women with urinary incontinence aged 40-64, who lived in a rural area were included in the study. The urinary incontinence management program was composed of urinary incontinence education, pelvic floor muscle exercise, behavior management using a voiding diary. The program had three weekly sessions. Knowledge about urinary incontinence, physical symptoms, self-efficacy, and urinary incontinence related quality of life were measured before and after the program. Results: After carrying the urinary incontinence management program, knowledge score improved significantly compared to before the program ($6.31{\pm}3.30$ vs $7.77{\pm}2.55$, p=.01). But the score for self-efficacy, and urinary incontinence related quality of life did not improve. Conclusion: The 3 week urinary incontinence program had an effect on knowledge related to urinary incontinence, but not self efficacy nor urinary incontinence related quality of life. Thus further study is required to better evaluate the effects of the urinary incontinence program.

Multinational Corporations (MNCs) are establishing globally-distributed R&D centers around the world. Firms can overcome resource constraints and achieve superior innovative performance not only by using internal resources but also acquiring knowledge from oversea R&D centers. This paper explores the key factors that have been cited as significant influences on the ability to transfer knowledge, an important area of knowledge management of MNCs. Also, we identify the emerging outcomes in terms of R&D transfer and for the education, employment, and retention of knowledge works in MNCs. The result will be helpful for both MNC's managers and governments' decision makers with respect to R&D centers.
