In National Curriculum of Science revised in 2007, free inquiry was newly introduced to increase student's interest in science and to foster creativity by having students make their own curiosity questions and find answers by themselves. The purpose of this study is to analyze elementary school students' perceptions on free science inquiry activities applying a brain-based evolutionary approach. For this study, 106 the fifth grade students participated, and then completed a questionnaire on free inquiry activities according to a brain-based evolutionary science teaching and learning principles. The students performed a series of steps of the Diversifying, Estimating-Evaluating-Executing, and Furthering activities in each of Affective, Behavioral, and Cognitive domains (ABC-DEF approach) and constructed their own free inquiry diary, then the observations by the researcher and interviews with the students were analyzed both quantitatively and qualitatively. The major results of the study were as follows: First, the majority of the students perceived the each domain and step positively although a few of them perceived negatively. The reasons perceived as negatively were categorized into two; preference dimension of like or dislike and ability dimension of metacognitive or self-reflective capacity. Also, they perceived the free inquiry experience in the form of ABC-DEF as helpful to understand the nature of scientists' scientific activities. Based on these findings, implications for supporting authentic inquiry in school science are discussed.

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.

In this study, Tongue fern (Pyrrosia lingua) plants that have been used traditionally as medicines. Their traditional medicinal uses, regions where indigenous people use the plants, parts of the plants used as medicines. This study was designed to assess the antioxidant and inhibition activities of extracts from P. lingua. In the P. lingua extracts was measured ethanol activity, 80.0% ethanol was high activity. The antioxidant activity was measured in 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-Azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), assays. DPPH and ABTS radical in this experiment, solid and phenolic of extract were tested, but only an average concentration of 100 ㎍/mL was used. However, the phenolic extract is shown phenolic activity reached a peak. Also, phenolic extracts ware reached peak water and ethanol extracts. As a result, using the phenolic extracts did other antioxidant assays such as DPPH, ABTS, protection factor, and thiobarbituric acid reactive substances at 50-200 ㎍/mL concentrations. The activity of elastase and collagenase, inhibiting their activities may retard skin aging. α-Glucosidase and α-amylase, inhibitors need to be explored for the benefit of postprandial hyperglycemia in diabetic patients. Activities of tyrosinase, hyaluronidase and xanthine oxidase inhibitors of these enzymes are increasingly important ingredients in cosmetics and medications to protect the skin against hyperpigmentation and skin aging. Inhibition effects were investigated using the P. lingua extracts at 50-200 ㎍/mL concentrations. The expression levels of enzyme inhibitions activities were decrease in dependent-concentrations manner when P. lingua extracts were treated.

We previously isolated Bacillus strains with high fibrinolytic activities (FAs) from cheonggukjang prepared by traditional ways. To test their potential as starters for cheonggukjang, soybean was fermented for 72 hr at $37^{\circ}C$ with each isolate and a control lab strain: B. subtilis CH3-25 (BS3-25), B. amyloliquefaciens CH51 (BA51), B. amyloliquefaciens CH86-1 (BA86-1), and B. subtilis 168 (BS168, control, lab strain). Viable cell numbers of all cheonggukjang samples rapidly increased and reached about $10^9$ CFU/g after 6 hr. During 72 hr, the initial pH of 6.3 rapidly increased to 8.1$\sim$8.2 for cheonggukjang fermented with BS3-25 or BA86-1, and 7.3 for those with BA51 or BS168. FAs and protease activities (acid, neutral, and alkaline) rapidly increased in cheonggukjang fermented with BS3-25, BA51, or BA86-1 during the first 12 hr. On the other hand, those of cheonggukjang fermented with BS168 slightly increased during the first 36 hr. There were significant changes in acid and neutral protease activities in cheonggukjang fermented with BA51 or BA86-1 during the 24 hr. Rapid increases of $\beta$-glucosidase activity corresponded well with rapid increases of $\alpha$-amylase and $\alpha$-galactosidase activities in addition to increases in antioxidant activities and the TPCs (total phenolic contents). The highest increase in the TPCs was observed in cheonggukjang fermented with BA86-1 while the least was that fermented with BS168.
