The study is to identify what the outcome of cyber university is, and develop the outcome-analysis model as a evaluation criteria of cyber university`s educational outcome. The outcome-analysis model of cyber university was developed in the first research and modified in the second research covering about a year period. In the first research, the first model which was mainly focused on the output of cyber university was developed being processed by 8 steps of review and examination. In the second research, the second model which was based on the systemic approach was developed by means of verification on the importance by the faculty of cyber universities and the experts of distance education. The outcome-analysis model of cyber university is composed of three aspects; input, process and output. Firstly, the input aspect is divided into students, university and social sectors. Secondly, the process aspect is divided into six sectors; curriculum, course development, course management, teaching and learning support, learner support, and system. Thirdly, the output aspect is divided into students, university and social sectors. The outcome-analysis model of cyber university would be a basis of quality management system for the cyber university so that it ultimately includes not only output aspect but also the input and process aspects which affect on the output. It is expected that the model which is composed of comprehensive criteria could be used as a systemic outcome-analysis model for cyber university.

Objectives : The purpose of this study was to examine what teaching behavior would have a good effect on learners in lecture-style instruction in the department of dental hygiene. Methods : The subjects in this study were 650 students who were in the three-year department of dental hygiene at four colleges in Gyeonggi Province and Chungcheong Province. After a survey was conducted, frequency analysis and ANOVA were utilized to analyze the collected data. The findings of the study were as follows. Results : The students put the highest value on knowledge among the factors of teaching behavior irrespective of their academic year, academic standing and learning style, followed by skills and attitude. Out of every subfactor, they set the highest value on a sense of humor regardless of their academic year, academic standing and learning style, and put the lowest value on the attitude factor such as enthusiasm. There were differences among the students in evaluation of the factors of teaching behavior according to academic year, and the students whose academic year was higher set a higher value on the factors of teaching behavior. There were no differences according to their academic standing and learning style. Conclusions : The dental hygiene students viewed the knowledge factor as the effective factor of teaching behavior, and regarded a sense of humor as the best subfactor. Although the attitude factor like enthusiasm is important, it seemed that the students hoped for the kind of instruction that would be delightful, intriguing and clearly convey what to learn.(J Korean Soc Dent Hygiene 2012;12(1):189-200)

Objectives. We developed PBL packages for oral health education and explored the course`s meaning of the packages for applying PBL to dental hygiene education. Methods. After PBL packages were developed and used, the components of the packages were compared to those of expository and practice centered instruction. Those are subject, main concept, an issue situation, degree of difficulty, achievement evaluation etc. Results. The PBL packages developed in this study provide problem situations that students might face in the clinic after graduation, and the packages stimulate independent problem-solving instead of relying on existing expository and practice-centered teaching practices that merely convey content. We assessed the application of problem-based learning, the preparation of educational plans, small grouping, tutor posting, and a variety of learning methods, and selected learners were interviewed to describe their PBL experiences. The significance of applying problem-based learning was also analyzed. The learners initially had difficulties with the PBL process, but became accustomed to it with experience, and this process learning did not disrupt the educational value. Conclusions. This study suggests ways to implement PBL in dental hygiene education.

The objective of this study was to examine the quality characteristics and antioxidant activity of yogurt containing hot water extract from maca. Four different levels (0, 4, 8, 12%) of maca extract were added to milk followed by fermentation with lactic acid bacteria at 37℃ for 12 hrs, and then the physicochemical properties of the samples were investigated. During 7 days of storage at 4±1℃, the acid production (pH and titratable acidity) of the yogurt increased with the addition of maca extract. The Hunter L value (lightness) decreased, while the b value (yellowness) increased as the maca extract level in the yogurt increased. Viable cell counts were not significantly different among the samples. The results of consumer acceptance tests showed that no significant differences in overall acceptability were observed between the yogurts containing 4% and 8% of maca extract and a control yogurt. The yogurt containing maca extract exhibited higher DPPH radical and superoxide anion radical scavenging activities than the control yogurt over the storage period.

Objectives. It was carried out in order to suggest basic materials for application to the dental-hygiene education field, which considers adoption of PBL, through verifying effects of PBL according to frequency of reflective journals prepared by learners. Methods. It was divided into three groups based on the number of preparing reflective journals targeting the second grade for Dept. of Dental Hygiene at 3-year college, prepared finally reflective journal for the definite classification, and then carried out paired t-test and GLM (General Linear Model) targeting the upper group (n=20) and the lower group (n=22). Results. The general problem-solving ability was shown the significant enhancement according to preparing reflective journal after experiencing PBL. As a result of comparing effects before and after learning by sub-element in each of the problem-solving ability test, the significant result wasn`t indicated in all of sub-elements. As a result of analyzing by dividing the reflective-journal number into upper group and lower group, the significant result was shown between groups in elements for selection of optimal plan (element 3), for establishment and execution in a plan (element 4), and for evaluation (element 5), which are 3 elements among 5 sub-elements. Also, the upper group for these 3 elements was increased the problem-solving ability. Conclusions. In the group of learners, who prepared lots of reflective journals, the problem-solving ability was indicated to be bullish trend after experiencing PBL. In the group of learners who prepared less was shown bearish trend. There is necessity for inducing learners to write reflective journal frequently to promote the effect of PBL.
