Reflecting the recent trends and needs of gifted education, this study set out to compare and analyze mathematically gifted elementary students and common students in self-efficacy and career attitude maturity, understand the characteristics of the former, and provide assistance for career education for both the groups. The subjects include 237 mathematically gifted elementary students and 221 common students in D Metropolitan City. The research findings were as follows: First, mathematically gifted elementary students turned out to have higher self-efficacy than common students at the significance level of .01 in the three self-efficacy subfactors, namely confidence, self-regulated efficacy, and task difficulty preference. The findings indicate that mathematically gifted elementary students have much confidence in themselves and strong faith in themselves, thus forming a habit of preferring a relatively high-level task by taking self-management and task difficulty into proper consideration. Second, mathematically gifted elementary students showed higher overall career attitude maturity than common students. There was significant difference at the significance level of .01 in decisiveness and preparedness between the two groups and significant difference at the significance level of .05 in assertiveness. However, there was no statistically significant difference in purposefulness and independence between the two groups. Finally, there were positive correlations at the significance level of .01 between all the subfactors of self-efficacy and those of career attitude maturity in all the subjects except for self-regulated efficacy and purposefulness, between which there were positive correlations at the significance level of .05. The mathematically gifted elementary students showed positive correlations between more subfactors of self-efficacy and career attitude maturity than common students. Given those findings, it is necessary to take differences in self-efficacy and career attitude maturity between mathematically gifted elementary students and common students into account when organizing and running a curriculum. The findings confirm the importance of providing students with various experiences fit for them and point to a need for helping mathematically gifted elementary students maintain a high level of self-efficacy and guiding them through career education with more appropriate career attitude maturity improvement programs.

In this study, volunteer experience(motive, durability, satisfaction, content) was set up as an independent variable, career maturity degree(determinacy, involvement, independence, tendency) was set up as a dependent variable, and the average difference and effect of the sub factors for each of them were reviewed. For this purpose, questionnaires were performed with 519 students at the middle schools and high schools in Busan. With 376 students having volunteer experiences among them, an analysis was done to find out the effect of volunteer experience on career maturity. The results of this study are as follows: First, whether having volunteer experience or not affected the career maturity among youths. That is the group with volunteer experience had higher level of interest, involvement and value in career and jobs than the group without them. Second, it showed that volunteer experience affected career maturity among youths. Specifically, career maturity was higher as their motive for volunteer activities was selfish, their satisfaction for volunteer activities was higher and they had more volunteer activities.

In this paper we describe interoperability maturity measurement, due to highlight a momentous issue on interoperability between heterogeneous distributed component based systems. it also suggests one of various ways for supporting interoperability between each other different component based systems, that is, using web services based mechanism and also revises 'LISI (Level of information systems interoperability)' model to measure interoperability maturity. We also develop the interoperability questionnaire based on the interoperability factors considered at each phase of component based development process, which is possible to measure interoperability maturity between heterogeneous distributed component systems. Based on revised interoperability maturity model and questionnaire we measure each interoperability maturity on examples of two different implementations, that is, web services and distributed object based mechanism. As a result, we suggest an enhanced interoperability way based on analysing problems af these measured results.

In an environment transformed by smart factories, measuring the current level of the manufacturing system, deriving improvement targets and tasks and increasing the level of manufacturing competitiveness become the basic activities of the company. However, research on the component analysis and maturity assessment to ensure the future competitiveness of the company is in progress and in the early stages. This study analyzed the existing research on various models, development process, and framework for manufacturing system. In addition, we designed a structural model by deriving the components of future manufacturing system through smart factory related maturity assessment studies. We designed a meta-model that includes an assesment model and a transformation model, and derived the framework development process to propose an integrated framework for the maturity assessment of the future manufacturing system. We verified it by applying it into an actual evaluation project of smart factory.

PURPOSE This study was intended to analyze the play-form of normal preschool children as related to age, sex, educational experience and social maturity. METHOD 1. Subjects The subjects of this study were eighty seven 3-, 4- and 5-year-old preschool children attending educational institutions in Seoul. 2. Instruments The instruments used in this study consisted of twenty one-minute observations in 5 preschool settings and a questionnaire designed to measure the children's social maturity filled in by their parents. The observations provided information on the children's free play, that is 1) play-form: solitary, parallel and group play 2) use/non-use of toys 3) behavior: play, activity, doing nothing, onlooking 4) stationary/moving dimensions 5) play group size The questionnaire measured such factors as communication, socialization, locomotion, self-help and self-direction. 3. Data Analysis Data analysis consisted of percentage and Chi square. RESULTS 1. Play-Form The relationship between age and play-form proved to be significant at the .05 level. That is, in both boys and girls, solitary play decreased with age and group play increased with age while parallel play maintained a similar position. The relationship between sex and play-form proved to be significant at the .05 level in 3-& 4-year-old children, but not significant in 5-year-old children. That is, in their $3^{rd}$ year boys engage in the solitary play more than girls and in their $4^{th}$ year boys engage in more group play than girls. 2. Toys Without differentiation of sex and age, cases of using toys in play exceed those cases where toys were not used. 3. Behavior The relationship between age and behavior proved to be significant at the .05 level in both boys and girls. That is, with increase of age, play decreased and activity increased in boys while play increased and doing nothing decreased in girls. 4. Moving Status Totally, moving occurred more frequently in play than stationary status. Moving proved not to have a significant relationship with age, but it did Navel a significant relationship with sex at the .05 level. That is, moving tended to increase with the increase in age in both boys and girls, but not at a significant level. Boys moved significantly more than girls in all three age levels. 5. The Relationship between Educational Experience and Play-Form There was a tendency for children with longer preschool experience to engage in less solitary play and more group play than children who had less than one semester of preschool experience, but this difference was not statistically significant. 6. The Relationship between Social Maturity and Play-Form The high social maturity group engaged in less solitary play and more group play than the low social maturity group, but this was not a statistically significant difference. 7. Play Group Size Play group size was 2~10 children, but the majority of play groups consisted of 2~3 children. There was a tendency for play groups composed of 2 children to decrease with age and play groups composed of 3 children to increase with age. No significant difference was found between the sexes in play group size.

In order to investigate the relationship between the menarche and the bone maturity of growing girls, the author interviewed about the date of menarche of 70 girls and assessed their bone maturity by hand-wrist radiographs. The results and conclusion were as iollows ; 1. The mean menarcheal age was $12.04{\pm}0.82$ year. 2. There was significant correlation between the time interval after menarche and the ossification stage. 3. The skeletal maturation level at menarche was stage SMI 7 and SMI 8. 4. There was statistically different among the time intervals after menarche according to the ossification stage. 5. The epiphyseal union of radius began about 2 years after menarche. According to this study, the probability of clinical use can be accepted in some range. In another words, skeletal age can be predicted by just interviewing the date and time interval of menarche without hand-wrist radiograph, also, with this information, the level of maxillofacial growth can be assessed.

Quality sorting of cut flowers is very essential to increase the value of products. There are many factors that determine the quality of cut flowers such as length, thickness, and straightness of stem, and color and maturity of bud. Among these factors, the straightness of stem and the maturity of bud are generally considered to be more difficult to evaluate. A prototype grading and sorting machine for cut flowers was developed and tested for a rose variety. The machine consisted of a chain-drive feed mechanism, a pneumatic discharge system, and a grading system utilizing color image processing and neural network. Artificial neural network algorithm was utilized to grade cut roses based on the straightness of stem and maturity of bud. Test results showed 89% agreement with human expert for the straightness of stem and 90% agreement for the maturity of bud. Average processing time for evaluating straightness of the stem and maturity of the bud were 1.01 and 0.44 second, respectively. Application of neural network eliminated difficulties in determining criteria of each grade category while maintaining similar level of classification error.
