The ever increasing demand for energy and the shortage of resources all over the world have generated interest in recycling renewable sources such as lignocelluloses which otherwise would go to waste and cause environmental pollution. Lignin is the incrustation material for cellulose and hemicellulose, therefore, cellulose and hemicellulose are not easily degraded. Recycling lignocellulosic wastes as agricultural material are benefit to everybody and everything. In order to improve ligninase and laccase production of Phanerochaete chrysosporium, BKM-F-1767 and Ceriporiopsis subvermispora, FP 90031-SP, were compared. The ligninase activity of P. chrysosporium was maximum on day 4.5 of shaking culture at 150 rpm 2.5 cm in a back and forth cycle. The laccase activity of C. subvermispora was maximum on day 5.5 for 2% malt extract+0.1% yeast extract+0.1% Tween 20+6 mM Benzyl alcohol culture medium at stationary state.

The purpose of this study was to develop the E-STEAM program emphasizing the engineering design process and apply them to young children to examine their effects on scientific problem-solving ability and communication ability. In order to develop the E-STEAM program, activities were organized by reviewing previous studies and websites related to STEAM and engineering education. The organized activities were selected as final activities after consulting with experts. To examine the effectiveness of the program, 50 subjects(experimental group: 25, control group:25) participated in K kindergarten in G city. The experimental group took part in the E-STEAM activities during 7 weeks, while the control group took part in the traditional science activities. The procedure for this study consisted of a pre-study, a pre-test, the treatment, and a post-test schedule. The results of this study were as follows: First, the experimental group showed significantly higher score than the control group in total problem-solving ability. Second, the experimental group showed significantly higher score than the control group in total communication ability. These findings suggest that the experience of E-STEAM activities for young children can be effective teaching-learning methods for young children's problem solving ability and communication ability.

This paper examines the aspect of the novel which appeared in the union of the male and female relationship of "OkSuki", one of the novels of the 19th century. "Oksuki" is a work focusing on the relationship between men and women. It takes a narrative structure based on the relationship. It shows various aspects of the relationship through the structure in which the pluralities of plural persons are repeated. Other events and illustrations, except for the talk, are both an occasion of the alliance and an auxiliary role. At the beginning of the work, the main character's parents are described in detail.By arranging the prophecies related to the relationship between the protagonist and the brothers, it suggests that subsequent narratives will flow into the center of the relationship. The male characters that make up the alliance are characteristically trained and have a good taste, and the Caines are colorfully colored. It is believed that the marriage pattern faithfully follows the medieval status order. The reason why the figure of the person who becomes his wife and the person of the concubine are set differently is because the image of the wife and the concubine are different from each other ideally. The characters who are going to be hungry are emphasized on the clause, efficacy, knowledge, and inner peace, and are actively involved in. On the other hand, conciliatory characters emphasize talent and craftsmanship, and their role is reduced after marriage. The wife is a person who has both Confucian culture and knowledge and is able to care for her husband and family well. Concultation is shaped as a person who can enjoy joyful life and emphasize more affection in relation with his wife.

The purpose of this study was to investigate the stage of concern and use level of early childhood teachers' STEAM, and to find out whether there is a difference in the stage of concern according to individual teachers' variables. The subjects were 242 teachers in charge of 3-5 years old kindergarten and daycare center in G city. The research tool was the stages of concern questionnaire (SoCQ). The collected data were converted to relative intensity by applying percentile conversion chart in the guidelines, and this was expressed as a concern profile graph, and t-test and ANOVA were performed to find out the difference in concern according to teacher's background variables. The research results are as follows. First, the stage of concern in early childhood teachers' STEAM was identified as a critical non-user profile. Second, the stage of concern in the teacher's STEAM was judged as a person who did not use, or was implemented for less than 2 years, and was a non-user or a novice. In addition, it was found that most of the teachers did not receive formal education for STEAM. third. There were differences in the educational background, career, current execution status of teachers, whether or not to take related courses in pre-service teacher education, and whether to plan for future implementation. And there were no differences in the majors and institution types of teachers. Based on these results, a support plan for changing the stage of concern of teachers about STEAM and improving the level of use was suggested.
