The purpose of this study was to investigate the effects of early storybook reading intervention participation on the first graders' language abilities in low income families. The subjects consisted of 148 first graders and their primary caregivers. The intervention group was composed of 100 first graders who participated in the early storybook reading intervention program in childcare or kindergarten. The comparison group comprised 48 first graders from equivalent social and economic backgrounds, who did not participate in the program. The language abilities of the children were tested and questionnaires regarding the home literacy environment, children's reading activities at home and parents' perceptions of their children's reading behaviors were completed by the children's primary caregivers. The data were analyzed by means of structural equation modeling. The results indicated that early intervention participation was directly associated with children's higher language abilities in first grade and indirectly influenced the children's language abilities through the home literacy environment, children's reading activities at home and parents' perceptions of their children's reading behaviors.

This study was designed to compare mothers' beliefs of literacy development and home literacy environment and to explore how the children interacted with their mother during literacy activities and how they used the strategies to develop knowledge of literacy. The qualitative data was collected from multiple sources of naturalistic information and analyzed through triangulation of diverse methods including participant observations in the home, parental during literacy events, written logs kept by the mothers, the children's writing products, three emergent assessment forms, and photographs. The three preschoolers and their mothers provided different literacy experiences to support their children's emerging conventional literacy development. Child 1's mother highly valued the rich home literacy environment and the child 1's initiative interactions during literacy events. Child 3's home literacy context was very similar to her Montessori classroom's phonic approach and writing skills. Child 2 was provided with an inappropriate literacy environment at home through direct instruction and an emphasis on correct writing. All of the children were interested and attended to story. Child 1 interacted with her mother in expanded cycles as child's initiation, mother's clarification, and child's evaluation, compared with the child 2's simple cycle and the child 3's classroom-like cycle as mother's initiation, child's response, and mother's evaluation. The children and their mothers employed a number of diverse strategies to understand knowledge of literacy. Importantly parent education needs to emphasize the importance of playful one to one mother-child interaction, a functional holistic literacy environment., and strategies for expanding child's knowledge with parent as mediator.

The aim of this study is to investigate the qualities for the reading education professionals and to suggest a training program of reading education professionals through comparing our educational programs for training of reading education professionals with those of U.S and Japan. The training program of reading education professionals in U.S is composed of Pedagogy and English language subjects and it emphasizes on literacy instruction. However, in Japan they make much account of the academic system of reading education and emphasize on various reading activities and the neighboring knowledge related with reading education. In our country, the program is composed with Korean language subjects concentrated on reading and comprehension. The training program of reading education professionals should consider three factors of reading such as readers, reading materials and reading professionals. It should include theory and philosophy and emphasize on educational experience and practice. It also should cover the neighboring knowledge related with reading education.

In the present study, we has been isolated the anti-cariogenic component, stigmasterol, from Aralia continentalis (A. continentalis) and identified by MS, $^1$H-NMR and $^{13}$C-NMR and also investigated the anti-cariogenic properties of stigmasterol. The methanol extract of ,A. continentalis showed concentration-dependent inhibitory activity against the growth and acid production of S. mutans. The MeOH extract was suspended in H$_2$O and sequentially partitioned with n-hexane, CHCl$_3$, EtOAc, and n-BuOH. The CHCl$_3$ fraction showed remarkable antibacterial activity against S. mutans. The anti-cariogenic compound, stigmasterol, has been isolated successively through the screening system and various chromatography methods. Anti-cariogenic properties of stigmasterol were also investigated. From this active chloroform subfraction, isolation and identification finally gave (24E)-stigmasta-5,22-dien-3${\beta}$-ol (stigmasterol) {[a]$_D\;^{25}$ -48.33$^{\circ}C$(C 0.28, CHCl$_3$)} by spectroscopic methods (MS, $^1$H-NMR and $^{13}$C-NMR) as an active principle. The compound, stigmasterol, showed significant growth, acid production, adhesion and water-insoluble glucan synthesis inhibitory effect against S. mutans. These results suggest that stigmasterol from ,A. continentalis may inhibit cariogenic properties of S. mutans and these properties may provide some scientific rationales that the local inhabitants used the extracts for treatment of dental diseases.

This study developed and evaluated a Seoul National University literacy program for multicultural family children (SNU-LPMFC). The program was developed to enhance Korean language ability for children from multicultural backgrounds. The characteristics of this program were education using fairy tales and nursery rhymes, individual education from home visiting teacher, and parent participation education for effective children's learning support. The effectiveness of this program was examined based on 54 young children and their mothers (34 in the experimental group and 20 in the control group). To examine the effect of SNU-LPMFC, we assessed children's literacy ability as pre-tests and post-tests as well as interviewed the home visiting teachers. After 8 weeks' field application, the experimental group exhibited higher scores than the control group in total language ability and phonology. Home visiting teachers highly praised the effectiveness of the program as the children showed a higher level of interest and attention. SNU-LPMFC was shown to be an effective program to improve multicultural family children's literacy. Implications for research and practice were discussed along with the main results of this study. This study extends the limitations of existing language education programs with uniform teaching methods, configured a customized education approach for children from multicultural families and helps develop concrete teaching material that validated its effectiveness.

The purpose of this study was to explore the types of mother's language and literacy information as they collaborated to write a letter during a 10-minute session. Subjects of the study consisted of 60 mothers and their children 10 boys and 10 girls each at the age of 3,4 and 5 The mothers' teaching language was analyzed on the basis of hoffman(1987)'s study and the types of information thant mothers and children exchanged during writing letters was analyzed by Burns and Casbergue (1992)'s categories. Frequency percentages and χ2 tests were used to analyze the data. The resuls of this study were as follows. 1. The types of the mothers' teaching language from the most to the least were mother-initiated statements mother-initiated questions and mother's responses to child's efforts. There were significant differences according to children's age in mothers' language. In the mother-initiated questions request questions were used most frequently and followed by interrogation questions and invitation questions next. The statements initiated by mothers were directive comments informative comments supportive comments insistence comments and invitation comments in order. Mothers' responses to child's efforts were corrects/controls additional cues confirmation promotion and praise in order. In all three types of the teaching language significant promotion and praise in order. In all three types of the teaching language significant differences were found according to children's age. 2. The types of information about writing were spelling content off task/preparation mechanical conventions and conceptual meaning of writing in order. Significant differences were found according to children's age. In the age group of 4-and 5-year-olds the mothers exchanged more information about spelling than the mothers of 3-years-olds who frequently used information about content and off task or preparation of writing the letter.

Streptococcus mutans is considered one of the primary etiologic agents of dental caries. we studied the effect of the ethanol extracts of Tribuli fructus (T. fructus) on the growth, biofilm formation, acid production, adhesion and insoluble glucan synthesis of S. mutans. The ethanol extracts of T. fructus showed concentration dependent inhibitory activity against the growth and acid production of S. mutans, and produced significant inhibition at the concentration of 0.025, 0.05, 0.1, 0.2, 0.3, 0.5 mg/ml compared to the control group. In the biofilm assay, the ethanol extracts of T. fructus inhibited formation of biofilm synthesized by S. mutans at the concentration of 0.05 mg/ml. The extracts markedly inhibited S. mutans adherence to HA treated with saliva, and cell adherence was repressed by more than 50% at the concentration 0.05 mg/ml. On the activity of glucosyltransferase which synthesizes water insoluble glucan form sucrose, ethanol extract of T. fructus showed more than 10% inhibition over the concentration of 0.025 mg/ml. Hence, we conclude that T. fructus might be a candidate of anticaries agent. Further studies are necessary to clarify the active constituents of T. fructus responsible for such biomolecular activities.

The purpose of this study is to investigate the effectiveness of education for information literacy by measuring information literacy of selected experimental group and controlled group from university students. Information literacy of each group was measured through structured questionnaires before and after taking the instruction course. The result showed there was a significant difference between two groups after the instruction. and the effectiveness of information literacy showed especially high in the area of information ethics and information analysis. It was also revealed that the education for information literacy is not affected by basic environmental factors at all. Also. students taken the course showed strong self-confidence and positive recognition in information literacy and library use, thus proved that education of information literacy is highly effective both in cognitive and attitudinal side for university students as a liberal arts course.

This study investigates on emergent process of the library in Republic of Indonesia through historical review. Under the Dutch and Japanese colonial control for around 350 years, library played a role as information control center. After independence of Republic of Indonesia, library was built as a result of government literacy project, but it has not been settled down as a public information center. Therefore, as an alternative activity, community libraries have been constructed to give a books and programs with its local community users in a private sectors. This situation represents that it is urgent to discuss with all society sectors to improve library role as a lifelong learning center and give a way to have a cultural sprit the citizens. The study suggests several policy agendas to improve library's public role in Indonesia society.

This study aimed to exploratorily investigate the new roles of libraries in the era of K-MOOC. For this, potential roles were derived and categorized from former researches and practices. And to evaluate the appropriacy of those roles, two expert surveys were conducted. Panel A was comprised of 30 professors who had been running K-MOOC classes and Panel B was comprised of 30 librarians of Universities that had adopted K-MOOC. The result shows that they both agree about distinct roles of library as information provider such as licensing and providing digital contents requested from information users, while technological part, for example, recording video and audio, managing website, and providing open access, was considered inappropriate because those roles were already taken by CTLs. Also, professors agree that information literacy education is required for teachers not just for students as the speed of technological development is too swift and librarians agree that they have to equipped with core competence in preparation for upcoming change by creating added value, establishing closer relationship with various educational and technological institutes, and securing organizational flexibility.
