This study analyzed the cases of three teacher communities participating in an innovative professional development program and clarified the characteristics and the process of lessons for mathematics-oriented convergence that were developed and applied during the program. Each of the teacher communities designed and implemented lessons according to the context of each community and the concept of lessons for mathematics-oriented convergence were developed and refined. The lessons developed by the three teacher communities were characterized as convergence problem posing lessons using technology, convergence of various subject content focused on mathematical concepts through team teaching, and convergence lessons according to students' achievement levels. The program contributed to teacher community activities by proving sustainable professional development in the area of convergence education, a connection between the content of their professional development and the context of the field, and opportunities for active participation in the process of developing and implementing the convergence lessons.

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 this study is to examine the characteristics and the relationships of PCK components of elementary school teacher in the chapter of electric circuit unit. The subjects of this study were two teachers serving as main teachers in the 5th grade and data were collected through qualitative research methods such as questionnaires for teachers, classroom observations and teacher interviews. The collected data were transcribed and then analyzed. Results of analysis showed that teacher A thought that science was a class to explore and study the principles of nature phenomena and scientific knowledge by themselves In addition, teacher A helped students to understand the content by using strategies of analogy. The teacher B conveyed the contents of text without any reconstruction. But teacher B understood the standards of curriculum, and didn't want to teach students over the standards. Based on the analysis, we could conclude that PCK is formed on the basis of knowledge and belief about curriculum and knowledge and belief about learners.

Development and Evaluation of the Effectiveness of a Web-Based Learning System Program for Nursing Education on Peritoneal Dialysis Ji-Soo Yoo(Professor, College of Nursing, Yonsei University, Seoul, Korea) Seong-Mi Moon(Doctoral Candidate, College of Nursing, Yonsei University, Seoul, Korea) The purpose of this study was to develop a nursing education program using a web-based learning system to teach peritoneal dialysis and to evaluate the effectiveness of the program. The program was developed in two steps. The first step was to develop the content using CVI, and the second was to program it using HTML. The program which was developed was evaluated with 50 nurses of whom 48 responded to the questionnaire. The results are as follows: Of the subjects, 85.4% responded that they were satisfied with this web-based learning system and 87.5% stated that they would recommend this system to nurses who are in other nursing education programs. Of the educational material charac- teristics, the item that the subjects evaluated as most valuable was "accuracy of the content". For system related charact- eristics, the item to which the subjects gave the most positive response was "clarity of the system tool marking" (81.3%). In conclusion, it was verified that a web-based learning system is an effective and satisfactory method for nursing education.

As the tendency of children's overdependence on smart phones increased, it was obligatory to carry out preventive education more than once a year in kindergarten and day care center, but there is no specific guidance on contents and method of preventive education. This is due to the lack of prior studies on the actual use of smartphones and the influence variables of infants and young children. The purpose of this study was to investigate the effects of use time, frequency of use, and sociological background variables on the actual situation of smartphone usage and overdependency on smartphone among 3-5 year old children nationwide. For the analysis, the frequency of the use of smartphone for 3-5 year old children was analyzed by frequency analysis, and the influence variables were correlated and multiple regression analysis. Research shows that smartphone overdependence of 3-5 year old children have an influence on the use time and frequency of use. The results should include content that restricts the use time and frequency of use of smartphones and prevention education programs for 3-5 year olds and young children. Suggesting a need for a transition to the educational method used.

The purpose of this study was to test the effects of Practical Problem-Based Home Economics Instruction (PPBHEI) on middle school students' creativity, focusing on the content on "clothing management and recycling." This study carried out quasi-experimental research with an independent variable of PPBHEI and a dependent variable of creativity. The experiment was based on a sample of 62 (31 in each group) second grade students in the Cheongju area over four class hours. ANCOVA was performed to examine pre-test and post-test differences between the experimental group and the control group. The results showed that PPBHEI did not improve the level of creativity but improved the level of creative motivation among the sub-elements of creativity (creative thinking, creative tendency, creative motivation). In particular, PPBHEI improved the level of independence in creative tendency, intrinsic motivation, and diligence in creative motivation. From the results of this study, it can be concluded that PPBHEI is effective in improving independence, intrinsic motivation, and diligence in respect of middle school students'creativity.

This research investigates the availability of information resources for visually impaired students in University libraries in Nigeria; a tool for inclusive University education. A Descriptive survey research design was adopted for the study and a total number of 20 University libraries took parts in the study. A self-constructed online questionnaire was designed and distributed to collect the data from respondents (librarians) using a simple random sampling technique. A total of 45 respondents filled out the online questionnaire, but 40 were valid and useful for analysis. The use of frequency count and percentages method of data analysis was adopted for this research work. The study reveals that most of the University libraries lacked information resources for visually impaired students, it was found that the inclusion of information resources for visually impaired persons will promote inclusive education and librarians' skills. The challenges hindering the availability of information resources to the visually impaired students are insufficient funds for maintenance, erratic power supply and inadequate skills by users, among others. Recommendations were made for the campaign for inclusive education and the provision of information resources for visually impaired students.

Presently, media for sanitation education consisting of a sanitation manual and a CD-ROM intended for restaurant employers and employees was developed and evaluated. The sanitation manual consisted of five principles: prevention of foodborne illness, personal hygiene, control of food production, instrument and equipment cleaning and sanitation, and management of environmental sanitation. The CD-ROM was composed of animations detailed real-life examples of Salmonella, Staphylococcus aureus, and Norovirus foodborned illness outbreaks; slides summarizing the five principles of the manual; and a poster entitled You can prevent foodborne illness listing and describing the principles. A 15 question evaluation survey was developed to gauge the efficacy of the animations. The survey was divided into five sections on comprehension of the instructions, content organization concerning understanding, content organization concerning the information presented, content organization concerning retention of interest (concentration), and recommendations concerning concentration. Ranked on a 5-point scale the survey produced a mean value of 3.80$\pm$0.39 and individual scores of 3.92$\pm$0.45 (learning instruction), 3.86$\pm$0.48 (understanding), 3.82$\pm$0.52 (information), 3.75$\pm$0.49 (concentration), and 3.67$\pm$0.58 (concentration-recommendation). Overall, evaluation results of the animation were good and easy to understand, with only a few respondents electing to watch the animations more than once. In terms of continuous and recurring education, sanitation training programs should be easy to learn and contain sufficient and specific examples of the importance of sanitation in achieving food safety.

Using poly(ethylene oxide) (PEO) as a polymer host, poly(ethylene glycol) (PEG) as a plasticizer, potassium iodide and iodine as sources of $I^-/{I_3}^-$ PEO-PEG-KI/$I_2$ polymer gel electrolytes were prepared. Based on the polymer gel electrolytes, solid-state dye-sensitized solar cell(DSSC)s were fabricated. The content of PEG in the electrolyte was changed from 0 to 85%. The electrolyte showed self-supporting form through whole range of the PEG content. As the PEG content increased, the ionic conductivity and ${I_3}^-$ diffusivity increased and the light-to electrical energy conversion efficiency increased under irradiation of 100 $mWcm^{-2}$ simulated sunlight.
