The purpose of this study was to compare the different environment among the young children of large and small cities and rural areas in Korea, in order to know how these different environment have an effect on the children's intellectual and emotional development. For this subjects, 2,700 questionares with 51 items were distributed to the infants' mothers in each area to interview and answer. About 1,800 questionaires were gathered from 3 metropolitan, 6 cities and 6 rural areas in (each 2 farming, fishing and mining villages) The results of analyzing these questionaires were like following; 1. The average number of children of each family was 2.5 in large cities, 3.0 in small cities and 3.6 in the rural areas. 2. White about 75% of infants' parents of large cities graduated college education, only 6% of the rural parents did it. Most infants' parents of the rural areas have only graduated the elementary school. 3. About 90% of the rural, small and large cities family have had radios and T.V sets, and 90% of infants watched T.V program for 2 hours a day in average. 4. While about 50% of large cities' young children were not reared by their mother's milk but by milk and other foods, about 95% of rural infants by breasting mills. 5. Young children of large cities were wearing about 5 months earlier than those of the rural. 6. While 20% children of cities were taught in the kindergarten, most children of the rural areas could not be taught in the kindergarten. 7. About 45% young children of the rural areas and cities were understood and taught reading, writing letters and numbers by their parents, brothers and sisters before entering primary school. 8. While 50% young children of large cities have had pianos and were taught music in kindergarten or piano tutor's, most of the rural areas have not had pianos and could not be taught music. 9. Most children's favorite music songs were T.V signals or C.M songs in both the rural and cities. 10. While most children of cities have had lots of children's pictures or fairy tale books. most infants of the rural areas have had nothing or a few. 11. As lots of infants could not find their pleasure resorts of sport tools outside, they used to play in side streets or publicroads with their friends. 12. While most infant's parents in cities wanted to make their infants lawyer or medicine doctor, most parents in rural areas wanted to make their children teacher or technician. 13. About a half of Korean infants have had their own rooms or have lived in it together with their brother or sister. In conclusion, as children of large cities have had more various kinds of cultural circumstances than the rural areas in aspects of cultural institutions' tools and environment of their parents' education, books, toys, pleasure resorts and their own rooms, the intellectual development of the former could be considered to surpass those of the latter. In other words, the average IQ points of urban's young children are 10 point higher than those of the rural areas, which means the better circumstance would affect the infant's intellectual development. Therefore, the government must support to make good circumstances of the children in the rural areas.

This study aims to analyze the relationship between scientific content knowledge of science-gifted elementary students and their expression of scientific creativity, and the characteristics of divided groups according to the levels of their scientific content knowledge and scientific creativity. A science-gifted program was implemented to 33 forth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea. The method of evaluating scientific knowledge was divided into well-structured paper-pencil test (asking specific and limited range of content knowledge of plants) and ill-structured descriptive test (stating all the knowledge they know about plants) to find out which methods were more related to scientific creativity. In addition, in order to find out the characteristics of each group according to the level of scientific content knowledge and scientific creativity, students were required to answer a questionnaire about their own self-perception of scientific knowledge and scientific creativity and how to obtain scientific knowledge. The main results of this study are as follows. First, Both well-structured paper-pencil test (r=.38) and ill-structured descriptive test (r=.51) results of elementary science gifted students were significantly correlated with scientific creativity. Second, As a result of the regression analysis on scientific creativity of science-gifted elementary students, both the knowledge measured by the two evaluation methods have the ability to explain scientific creativity. Third, the students were categorized into four groups according to the levels of their scientific content knowledge and their expression of scientific creativity, and the result showed that the higher the knowledge of science, the higher the scientific creativity. Fourth, the description about self-perception of scientific knowledge revealed that the highest percentage of Type LL students of all 13 students (53.8%, 7 students) answered 'I have little knowledge of plants because I have little interest in them.' Fifth, the description about self-perception of scientific knowledge revealed that the highest percentage of Type HH students of all 15 students (40%, 6 students) answered 'I think my science creativity is high through my experience of scientific creativity. Sixth, the responses to the Questionnaire revealed that 'reading' was the most popular way to obtain scientific knowledge, with 27 out of total 33 students choosing it. In particular, all 18 students from Type HH (high scientific knowledge and high scientific creativity) and Type HL (high scientific knowledge and low scientific creativity) - those with high scientific knowledge - gave that response. On the basis of this research, we should explore practical teaching methods and environment for gifted students to improve their scientific creativity by revealing the nature of the factors that affect scientific creativity and analyzing relationship between knowledge and scientific creativity.

Purpose : To investigate the change of bone healing process after endodontic treatment of the tooth with an apical lesion by fractal analysis. Materials and Methods Radiographic images of 35 teeth from 33 patients taken on first diagnosis, 6 months, and 1 year after endodontic treatment were selected. Radiographic images were taken by JUPITER Computerized Dental X-ray $System^{(R)}$. Fractal dimensions were calculated three times at each area by Scion Image $PC^{(R)}$ program. Rectangular region of interest $(30\times30)$ were selected at apical lesion and normal apex of each image. Results : The fractal dimension at apical lesion of first diagnosis $(L_0)$ is $0.940{\pm}0.361$ and that of normal area $(N_0)$ is $1.186{\pm}0.727(p<0.05)$. Fractal dimension at apical lesion of 6 months after endodontic treatment $(L_1)$ is $1.076{\pm}0.069$ and that of normal area $ (N_1)$ is $1.192{\pm}0.055(p<0.05)$. Fractal dimension at apical lesion of 1 year after endodontic treatment $(L_2)$ is $1.163{\pm}0.074$ and that of normal area $(N_2)$ is $1.225{\pm}0.079(p<0.05)$. After endodontic treatment, the fractal dimensions at each apical lesions depending on time showed statistically significant difference. And there are statistically significant different between normal area and apical lesion on first diagnosis, 6 months after, 1 year after. But the differences were grow smaller as time flows. Conclusion : The evaluation of the prognosis after the endodontic treatment of the apical lesion was estimated by bone regeneration in apical region. Fractal analysis was attempted to overcome the limit of subjective reading, and as a result the change of the bone during the healing process was able to be detected objectively and quantitatively.

Learning at the elbow of scientist is a well-known educational approach to improve students' understanding of science and scientific practice. This study, in the perspective of legitimate peripheral participation in a community of practice, explores how students' scientific practice and perception could be shifted through R&E program with the development of participation. Data from participant observation for 18 months and in-depth interviews were analyzed based on constant comparative method to extract common characteristics of students' participation and major shifts in their scientific practices and perceptions. Students' development of participation was categorized into three stages: legitimate, peripheral, and full participation. In the stage of peripheral participation, students perceived themselves as mere students and showed passive engagement. They just followed the directions of researchers and didn't know what they should be doing. But through continuous participation, students showed enhanced engagement like voluntary article reading, role assignments, and establishing norms in a community of practice with the reference of scientists'. In this stage of transitional participation, students also showed a deepened perception on everyday life of scientist and the community of scientist. And finally in the stage of full participation, students showed responsibility and ownership on research and continuous efforts to refine their research. They recognized themselves as beginning scientists. With these findings, this paper highlighted the dynamic processes of students' development of scientific practices and identity through R&E participation. It also suggests implications for research programs for education, especially for students who have already articulated a science-related career but still have only foggy notions about science.

The full-length heat shock protein 88 (HSP88) complementary DNA (cDNA) of Paecilomyces tenuipes Jocheon-1 was obtained by screening the Paecilomyces tenuipes (P. tenuipes) Jocheon-1 Uni-Zap cDNA library and performing 5' RACE polymerase chain reaction (PCR). The P. tenuipes Jocheon-1 HSP88 cDNA contained an open reading frame (ORF) of 2,139-basepair encoding 713 amino acid residues. The deduced amino acid sequence of the P. tenuipe s Jocheon-1 HSP88 cDNA showed 77% identity to Nectria haematococca HSP88 and 45-76% identity to other fungal homologous HSP88s. Phylogenetic analysis and BLAST program analysis confirmed that the deduced amino acid sequences of the P. tenuipes Jocheon-1 HSP88 gene belonged to the ascomycetes group within the fungal clade. The P. tenuipes Jocheon-1 HSP88 also contained the conserved ATPase domain at the N-terminal region. The cDNA encoding P. tenuipes Jocheon-1 HSP88 was expressed as an 88 kilodalton (kDa) polypeptide in baculovirus-infected insect Sf9 cells. Under higher temperature conditions for the growth of the entomopathogenic fungus, mRNA expression of P. tenuipes Jocheon-1 HSP88 was quantified by real time PCR (qPCR). The results showed that heat shock stress induced a higher level of mRNA expression compared to normal growth conditions.

This study was carried out on specialized library librarians to investigate the status and overall satisfaction of specialized services and to compare the degree of importance and satisfaction of specialized subject data, specialized service places, specialization programs, specialized subject area facilities and environment based on ISA technique in order to derive problems and improvement measures for the operation of specialized libraries. As results, first, it was found that a specialized library subject should be selected based on the characteristics, history, and resources of the library location as well as based on the demand survey of the local residents and users. Second, based on the appropriate program type of specialized subject and the results from users' demand surveys, specialized libraries should develop different types of experience-type, lecture-type, view-type and the likes. Third, specialized library space types can be divided into integrated type, independent-in-integration type, and independent type. Even though it is most ideal to provide independently specialized space, the space must be constructed considering the circumstances and subject of specialization of each library. Fourth, specialized libraries should have at least one dedicated specialist in the corresponding subject. Dedicated specialists should provide lending and reference services related to the specialization such as tidying, browsing, reading and operating specialized programs. And a dedicated specialist must be an expert in the specialized subject and also a librarian who is responsible of the general library operation.

The purpose of this study is to find out what kind of experience docent programs provide to visitors in museums by means of Giorgi's phenomenological method. In-depth interview was conducted with 6 visitors who had experienced firsthand. As a result of the coding based upon Giorgi's method, it was divided into 6 categories and 21 subcategories, and the following results were obtained. First, the reason that the subjects of the study participated in the docent program was due to factors such as information, coincidence, induction of companions, and habits. Second, from participating in the docent guide, they felt that the docent led them to actively visit the exhibition, get the educational effect, and generate interest and curiosity. Third, looking at the reaction after participating in the docent guide, in addition to the positive influence, the docent's reading-like explanation and the problem of the microphone facility were negative experiences. Through this study, it was confirmed that there were many visitors who recognized that the docent guide was helpful in viewing the exhibition and experienced positive reactions. In addition, in the evaluation of the commentary of docent, there was a difference of views between art-related majors and non-majors. In addition, as a result of analyzing the participants' experiences according to Holt's frame of experiential consumption, it was found that the docent experience was a comprehensive consumption behavior appearing in all four fields.
