Among many factors that affect the development of the talent of gifted children, the family factor that first finds and cultivates the talent of gifted children is quite important. The researches on the family of gifted children are mostly concentrated on physical environment out of the home environment, neglecting psychological environment. Although the recreational activity of family with gifted children considerably contributes to the emotional, intellectual and social development of gifted children themselves and to the improvement of life quality of the family members, the recreation of family with gifted children has not yet been studied. Thus, the objective of this research is to present basic materials for seeking the direction to educate parents and to support family with gifted children in order to encourage synergy effect in emotional and social growth of family with gifted children by surveying the property of recreation of family with gifted children. The result of result is as follows. First, the type of family with gifted children tends to be remarkably biased to 'family-oriented activity' and 'elf-development activity.' Second, verifying the significant level of motive for recreational activity of family with gifted children at the variables such as number of family members, parents' age, parents' education level, parents' occupation, etc, it was concluded that they were not statistically significant. The result of this research suggests that education and support for efficient recreation of family with gifted children is necessary to achieve healthy talent of gifted children.

웹과 같은 분산 환경에서는, 웹 브라우저 상에서 SQL 형식의 공간 질의를 수행시키는 것과 또한 서버로부터 그 질의 결과를 보는 것이 가능하다. 그러나, 격자 이미지(raster image)와 같은 대용량 공간 데이타를 포함하는 질의 결과를 웹 브라우징할 때 발생하는 많은 문제점들 중에서, 사용자 응답 시간의 지연은 매우 중요한 문제이다. 본 논문에서는 사용자의 재요청(callback) 접근 패턴이 공간적 근접성(spatial locality)을 따른다는 가정하에서의, 사용자 응답 시간을 최소화하기 위한 새로운 프리페치(prefetch) 전략에 대해서 서술한다. 본 논문의 프리페치 전략은 다음과 같이 요약될 수 있다. 첫째, 프리페치 알고리즘은 사용자의 접근 패턴을 잘 반영하는 힐버트 곡선(Hilbert-curve) 모델을 바탕으로 한다. 둘째, 프리페치 전송 비용을 줄이기 위해서 사용자의 재요청 시간 간격(think time)을 이용한다. 본 논문에서는, 힐버트 곡선을 이용한 프리페치 전략의 성능 평가를 위해서 다양한 실험을 하였으며, 그 결과로 프리페치를 하지 않는 방식보다 높은 성능 향상이 있음을 보인다.Abstract In distributed environment(e.g., WWW), it would be possible for the users to submit SQL-like spatial queries and to see their query results from the server on the Web browser. However, of many obstacles which result from browsing query results including large spatial data such as raster image, the delay of user response time is very critical. In this paper we present a new prefetch policy which can alleviate user response time on the assumption that user's callback access pattern has spatial locality. Our prefetch policy can be summerized as follows: 1) our prefetch algorithm is based on the Hibert-curve model which well replects user's access pattern, and 2) it utilizes user's callback interval to reduce prefetch network transmission cost. In this paper we conducted diverse experiments to show that our prefetch policy achieves higher performance improvement compared to other non-prefetch methods.

As studies on ubiquitous computing are actively conducted, desire for various services, including image transmission storage, search and remote monitoring. has been expanding into mobile environment as well as to PCs. while CCTV (closed circuit TV) and un DVR (Digital video Recording) are used in places where security service such as intrusion detection system is required, these are high-end equipment. So it is not easy for ordinary users or household and small-sized companies to use them. Besides, they are difficult to be carried and camera solution for mobile device does not support high-quality function and provides low-definition of QVGA for picture quality. Therefore, in this study, design and implementation of embedded system of high-definition image transmission for ubiquitous mobile device which is not inferior to PC or DVR are described. To this end, usage of dedicated CPU for mobile device and design and implementation of MPEG-4 H/W CODEC also are examined. The implemented system showed excellent performance in mobile environment, in terms of speed, picture quality.

Objective: The purpose is to verify that whether there are significant correlation between parent-teacher cooperation, quality of home environment, and mathematical interaction of parents and cognitive development of 3-year-olds, and the quality of home environment and mathematical interaction mediate the relationship between the parent-teacher cooperation and the cognitive development. Methods: A test was performed on 110 3-year-olds enrolledin a daycare center located in city S, and a questionnaire survey was conducted on their parents. We analyzed our data using SPSS WIN 21.0 and pearson's correlation, tested the mediating effect using regression, and used the Sobel test to check significance of the mediating effect. Results: Cognitive development of 3-year-olds was correlated with the parent- teacher cooperation, the quality of home environment, and mathematical interaction of parents. The quality of home environment showed complete mediating effect on the relationship between the parent-teacher cooperation and the cognitive development, and the mathematical interaction showed complete mediating effect on the relationship between the parent-teacher cooperation and the cognitive development. Conclusion/Implications: The parent-teacher cooperation indirectly predicts the cognitive development through the quality of home environment and the mathematical interaction. This research can contribute to the development of the family- institution connection program to facilitate the parent-teacher cooperation.

To improve the quality of healthcare and build up the health delivery system, electronic health record system is important for healthcare institutions providing health services. However, the systems currently operated in domestic healthcare institutions use independent software interface with distributed environment for data search and process. Therefore, it raises an additional expense to buy or develop each interface module when there is a link to new system and the problem of complexity. To solve these problems, this study implemented the service oriented architecture basis for home nursing service and carried out an assessment. The study defined the process modeling and business requirements based on the scenario of service and drew 17 suitable services based on five verification items for service design. To draw the final service, seven services were selected by service litmus test (SLT). The study found that, by the improvement of business process for healthcare service support department, SOA based information system has an effect of time reduction of patient processing time. In conclusion, to enable the hospital information system to cope with various demands of healthcare consumers, it is necessary to consider the application of SOA technology which has excellent interoperability, reusability and maintenance.
