The purpose of this study was to develop Team Based Learning (TBL) course for students majoring skin care and analyze the effectiveness as well as derive improvement plans. TBL focuses on putting pre-class learning about learning content and the time saved by it into practice activities that apply what is learned. The ADDIE model and the TBL model were applied as the developmental research methodology, and the 'skin care' subject, which was previously taught by lecture base, was redesigned as a TBL class. In addition, the study developed weekly based pre-class learning materials, quiz items for checking pre-class learning, and the team activities' plan. Then, an experimental study was conducted with 43 university students and the effects of TBL instruction were analyzed as follows. First, students who participated in the TBL class showed higher achievement than those who participated in the lecture class, which is a comparative group, especially in the academic achievement that evaluated the acquisition and application of the major concept. Second, there was no significant difference in pretest and posttest results on problem solving ability and cooperative self-efficacy for TBL students. Third, overall satisfaction with TBL class was 4.0, which is high. The discussion of these findings was described, and three suggestions for improving and researching TBL classes were presented.

This study aims to reflect the origin and the meaning of open education and to derive pedagogical principles for open mathematics education. Open education originates from Socrates who was the founder of discovery learning and has been developed by Locke, Rousseau, Froebel, Montessori, Dewey, Piaget, and so on. Thus open education is based on Humanism and Piaget's psychology. The aim of open education consists in developing potentials of children. The characteristics of open education can be summarized as follows: open curriculum, individualized instruction, diverse group organization and various instruction models, rich educational environment, and cooperative interaction based on open human relations. After considering the aims and the characteristics of open education, this study tries to suggest the aims and the directions for open mathematics education according to the philosophy of open education. The aim of open mathematics education is to develop mathematical potentials of children and to foster their mathematical appreciative view. In order to realize the aim, this study suggests five pedagogical principles. Firstly, the mathematical knowledge of children should be integrated by structurizing. Secondly, exploration activities for all kinds of real and concrete situations should be starting points of mathematics learning for the children. Thirdly, open-ended problem approach can facilitate children's diverse ways of thinking. Fourthly, the mathematics educators should emphasize the social interaction through small-group cooperation. Finally, rich educational environment should be provided by offering concrete and diverse material. In order to make open mathematics education effective, some considerations are required in terms of open mathematics curriculum, integrated construction of textbooks, autonomy of teachers and inquiry into children's mathematical capability.

This study is to implement a model of CPC-mentoring program based on the mentoring theory and research environment analysis as well as to present the operation case of teaching and learning in colleges. Major research results should use the practical research methods utilizing the statistical program in order to verify the effectiveness of the program of CPC-mentoring program by comparing the before with the after of running the CPC-mentoring program of the research objects, comparison group (61 people) and experiment group (33 people). After running the CPC-mentoring program, whether there was a certification's acquisition or not of the comparison group and the experiment group, a statistically significant difference between the comparison group 34.3% (21) and the experiment group 72.7% (24), (p<0.05) was shown. The goal of the students participating in the CPC-mentoring program was to help one another in order to obtain certification. moreover, by engaging in mutually developing human relationship activities thru various methods, such as adaptation of college life, development of sociality, graduation, etc., good cooperative relationships with one another as well as further development of the relationship was formed. CPC-mentoring program is neither doing only people that want nor being effective for people only that want. A successful matching will naturally lead to all success since mentoring is human relationships is the misunderstanding. The role of a mentoring coordinator(professor) for the operation of a successful CPC-mentoring program and for the application method of detailed CPC-mentoring program was set. In addition, by considering the connectivity with the counseling guidance (shared and individual guidance) of students, which is the characterization direction of technical department of the college, it is expected to make a positive contribution if utilized in a multilateral manner.

BACKGROUND/OBJECTIVES: Ultraviolet radiation (UV) is a major cause of skin photoaging. Previous studies reported that ethanol extract (PET) of Prunus persica (L.) Batsch flowers (PPF, peach flowers) and its subfractions, particularly the ethylacetate (PEA) and n-butanol extracts (PBT), have potent antioxidant activity and attenuate the UV-induced matrix metalloproteinase (MMP) expression in human skin cells. In this study, we investigated the protective activity of PPF extract against UV-induced photoaging in a mouse model. MATERIALS/METHODS: Hairless mice were treated with PET or a mixture of PEA and PBT either topically or orally along with UV irradiation. Histological changes and biochemical alterations of mouse skin were examined. Major phenolic compounds in PPF extract were analyzed using an ACQUITY UPLC system. RESULTS: The overall effects of topical and oral treatments with PPF extract on the UV-induced skin responses exhibited similar patterns. In both experiments, the mixture of PEA and PBT significantly inhibited the UV-induced skin and epidermal thickening, while PET inhibited only the UV-induced epidermal thickening. Treatment of PET or the mixture of PEA and PBT significantly inhibited the UV-induced MMP-13 expression, but not type I collagen expression. Topical treatment of the mixture of PEA and PBT with UV irradiation significantly elevated catalase, superoxide dismutase (SOD) and glutathione-peroxidase (GPx) activities in the skin compared to those in the UV irradiated control group, while oral treatment of the mixture of PEA and PBT or PET elevated only catalase and SOD activities, but not GPx. Thirteen phytochemical compounds including 4-O-caffeoylquinic acid, cimicifugic acid E and B, quercetin-3-O-rhamnoside and kaempferol glycoside derivatives were identified in the PPF extract. CONCLUSIONS: These results demonstrate that treatment with PET or the mixture of PEA and PBT, both topically or orally, attenuates UV-induced photoaging via the cooperative interactions of phenolic components having anti-oxidative and collagen-protective activities.

The objective of this study is to suggest the developmental tasks for the successful fostering the Farmer's Study Group which have been guided by the agricultural extension work since 1994 in Korea. The 3,278 farmers study groups with 148,420 memberships have been organized in field of grains, cash crop, horticulture, livestock, improving living conditions, food processing and so on. Although the number of study groups have rapidly expanded, there also are tasks to be secured for their successful development in terms of (a) desirable phase of the study groups and goals of its fostering, (b) managements / administration of them, (c) long-term tasks to be reviewed. With regard to the desirable phase of the study groups and goals of its fostering, they should secure differential mission and the way of works compare to the other farmer's groups. Also, there should be consensus on the proper number of study groups to be fostered with a agricultural technical center at local level. With regard to the managements / administration of the study groups, there should be the different support, assistance and guidance according to the developmental level of the groups. For these, there should be evaluation works on the groups, and guidance manuals for the extension workers. Also extension works should facilitate the establishment of networks among groups over the counties. Finally, to establish the nationwide association in hierarchy and to make the cooperative works with similar farmer's group, doing the value-added activities rather than mere information exchange, and the introduction of capacity building programs for the extension workers are long-term tasks needed to review for the successful fostering study groups.
