Misconceptions are one of the most important and long-lasting studied themes on science education. It is because their nature is obstinate and settled as well as they corrupt students' understanding of science concepts. This study examines whether preservice elementary school teachers enrolled in biology teaching material research course changed positively on science teaching efficacy and correcting life science misconceptions when they used the handbook developed for this study. The handbook comprises 203 life science concepts surveyed among preservice teachers holding from advanced researches and arranged by 2007 Revised Science Curriculum. 107 preservice elementary school teachers participated in the study. Forty-six (46) of them were assigned to the experimental group and the other 61 to the control group. ANOVA was conducted for analyzing data. Science Teaching Efficacy Belief Instrument (STEBI) and the life science misconception test which was developed for this study, were administrated as assessing instruments for pretest and posttest. The experimental group, using the handbook, acquired higher scores in both tests on statistical significance level than the control group who were not using the handbook. The results indicate the handbook developed for correcting life science misconceptions for this study is effective in enhancing science teaching efficacy and correcting life science misconceptions.

This study was performed to determine the whitening effect of several solvent fractions of Diospyros kaki extracts. Fractions from ethanol extracts of D. kaki were prepared by a systematic fractionation procedure using hexane, ethyl acetate, butanol, and $H_2O$. The ethyl acetate fractions were used to evaluate the inhibitory effects on tyrosinase activity and melanin synthesis in B16F10 melanoma cells. Ethyl acetate fractions suppressed the expression of tyrosinase, TRP-1 and TRP-2 in B16F10 melanoma cells. These results showed that ethyl acetate fractions of D. kaki could be developed as a skin whitening material in cosmetics.

Both interests in nature-friendly education and demands for nature experience program are steadily increasing in children education field in korea. This study aims to find out that five-sense experience-activity with healing factors of forest can have an effect on both self-efficacy and respectful recognition of life of children. 5-year-old young children were chosen as the subjects for this study. Test group participated two times a week in the special forest class in a children education institute in Chungju oo-dong while control group did not. Both test group and control group were composed of 20 young children respectively and each group were 11 boys and 9 girls respectively. The five senses experience activity program was conducted two sessions a week from 8 August to 20 September in 2016 and each session was one hour (60 minutes) long. Five senses experience activity is an activity that young children awaken their five senses in the forest, recognize seasonal change with their five senses, build up their selves and become intimate with nature. Before and after the program self- efficacy test and respectful recognition of life test were conducted and the data was analyzed using SPSS 18.0 program. The results indicated that after participating five senses experience activity program both children's self-efficacy which means having positive-thinking and self-confidence and respectful recognition of life which means valuing nature coexisting with nature were improved significantly(p<0.05). Through five senses experience activity young children felt nature freely and to their heart's content with their bodies and five senses experience activity had better positive impacts on children's self- efficacy and respectful recognition of life than classroom activities.

Huge amount of persimmon peels, which are byproducts usually arising after making dried persimmons from fresh persimmons, are generated in fall, every year. As the dry matter of persimmon peel contains carbohydrates over 80%, it could be a good candidate for feed. In this study, we evaluated the persimmon peel as a feed resource for a hen laying eggs. Persimmon peel has lower ratio of crude protein and fat composition while higher ratio of crude fiber composition compared to a basal laying hen feed. Feeding the persimmon peel by adding to the feed at the level of 2% or 5% did not affect the egg-laying rate from beginning to the peak of laying. In addition, feeding the persimmon peel did not affect the egg quality either, as the pH, Haugh unit, yolk color and shell thickness of the egg were not different from each other. The composition of amino acids and fatty acids were also almost same for each other, except for the linolenic acid which was slightly higher in the persimmon peel feeding groups. In conclusion, addition of persimmon peel to the feed up to 5% might be helpful to increase the income and reduce the waste produced from the agricultural byproduct.

This study evaluated the effects of presoaking apple slices in 2 or 5% brine solution prior to air-drying at $50^{\circ}C$. Several quality factors of the dried apples were measured including moisture content (MC), water activity ($a_w$), shear force, color values, appearance and consumer likability. Except at time 0, the $a_w$ of presoaked samples was lower than those of control during and after drying. The relationship between MC and water activity during drying was well-fit by an exponential model. During drying, the moisture contents of presoaked samples were slightly higher than control samples with no presoaking. However, the $a_w$ of presoaked slices were lower than control at a given drying time. At a given $a_w$, presoaked slices had higher moisture content. The shear force was lower for samples presoaked in brine solution, particularly at shorter drying times. Presoaked apple slices also were lighter in color after drying than controls. Sensory evaluations suggest that presoaking of apple slices before drying may help enhance palatability. Samples presoaked in 2% brine solution had the highest scores for taste, texture and overallacceptability, while those presoaked in 5% brine solution had the highest scores for appearance.

The purpose of this study is to investigate the factors affecting the respect for life of nursing students and to prepare the basic data for developing educational programs to establish proper awareness of the life of nursing students and nurturing it. This is a descriptive research study. A total of 146 nursing students were included in this study. Data analysis was performed using t-test, ANOVA, Pearson correlation coefficients, and multiple regression. The results of this study confirmed the meaning of life, spiritual wellbeing, and attitude toward death as factors influencing respect and will for life. The explanatory power of these three factors was 26.3%. Therefore, nursing students will be able to cultivate respect for life by increasing their understanding of the meaning of life, improving their level of spiritual well-being, and reducing their negative attitudes about death. Also, in order to improve the respect for life of nursing students, it will be possible to develop an intervention program to improve life respect including the factors identified in this study. Ultimately, it is expected to grow into a nurse who can provide real help to patients who are at the end of life or who are dying.

A response surface method based on a central composite design experiment was used to determine the optimum conditions for pretreatment of persimmon peel. It was mathematically predicted that the maximum amount of reducing sugars would be obtained at an $H_2SO_4$ concentration of 1.77% (w/v) and a heat treatment time of 26.4 min. A reducing sugar concentration of 63.23 g/l was obtained under the optimum pretreatment conditions determined by RSM. Under anaerobic growth conditions, Saccharomyces cerevisiae NK28 produced 15.52 g/l of ethanol with a yield of 0.34 g ethanol/g glucose from pretreated persimmon peel, which corresponded to 14% and 26% enhancements in ethanol productivity and ethanol yield, respectively, compared with those obtained in aerobic growth conditions. This study suggests that persimmon peel might be a useful substrate for bioethanol production by yeast fermentation.
