The government of South Korea discusses ways to expand computer science education to solve the digital divide. In-service elementary school teachers are also aware of the need for computer science education, with 77.3% of those who responded positively to the expansion of computer science education. The participating elementary school in this study has conducted computer science education for more than an hour per a week since the 1980s. As a result of a survey, the proportion of students taking private education was 16.2%. It shows 50.3% lower than 66.5% of other surveys conducted in 2021, which means the effectiveness in reducing private education when continuous computer science education is being conducted in the school system. In the case study analysis, teachers pointed out that the instructional content varies by instructors due to the absence of the national curriculum. The parents recognized the importance of computer science education but did not know the learning content and mentioned the necessity of the national computer science education curriculum. It means that computer science education should provide a universal educational opportunity as an independent subject in elementary schools for nurturing future talents.

Multilayer co-extrusion blown film construction is a popular technique for producing plastic films for various packaging industries. Automated detection of defective films can improve the quality of film production process. In this paper, we propose a film inspection system that can detect and classify film defects robustly. In our system, first, film images are acquired through a high speed line-scan camera under an appropriate lighting system. In order to detect and classify film defects, an inspection algorithm is developed. The algorithm divides the typical film defects into two groups: intensity-based and texture-based. Intensity-based defects are classified based on geometric features. Whereas, to classify texture-based defects, a texture analysis technique based on local binary pattern (LBP) is adopted. Experimental results revealed that our film inspection system is effective in detecting and classifying defects for the multilayer co-extrusion blown film construction line.

The purpose of the research is to designing of web-based expert system in assessment, programming, evaluation for infants and young children with developmental disability. For this purpose, research articles such as curriculum-based assessment evaluation, web-based expert system, use of the computer technology in special education were analyzed. The design of web-based expert system for infants and young children with developmental disability connected with information analysis, optimum levels, data collection, data analysis, decision-making, and intervention.

The general objectives of this study were to develop a health education management information system to effectively deal with community health problems. This study aimed at 1) to development an health education management information system, and 2) to offer computer-based communication channels among the District Health System components such as health center, health subcenters, and community hospital, 3) lastly, to identify the key issues and effectiveness of health education. Major findings of the study were as follows: The major benefits and significances of this information system included: improvement of quality of health education statistics by reducing manual data processing, improvement of productivity of health educators by reducing paper works, improvement of decision-making capability of managers by providing more information for planning, organizing, and evaluating health education programes, and improvement of communication flow among health institutions. Based on the findings of the study, the following are recommended: (1) The health education information system will connect with computerized information systems of various health-related institutions in a district and computer-based communication channels among them, and of the superior agencies in the future. (2) The major functions of the computerized health education program are: to keep client medical records, to inquire about information on the client and his family's history. (3) The program will provide outputs in various forms, such as files for patient records, data on some chronic diseases, information on the patient and his family members, and various kinds of statistics.

초중등학교에서는 교육 목적의 설문조사를 종종 실시하고 있다. 유료 시스템을 이용하거나 오프라인 설문을 하거나 클라우드 서비스 사이트를 이용하곤 한다. 라임서베이는 학교내에서 설치 운영이 가능한 오픈 소스이지만 사용자 인터페이스가 불편하게 느껴지는 점이 있어 그 사용이 적은 편인데, 본 연구에서는 이를 개선함으로써 사용을 보다 원활하게 하고자 한다.

The primary purpose of security mechanisms in a computer systems is to control the access to information. There are two types of access control mechanisms to be used typically. One is discretionary access control(DAC) and another is mandatory access control(MAC). In this study an access control mechanism is introduced for secure access path in security system. The security policy of this access control is that no disclosure of information and no unauthorized modification of information. To make this access control correspond to security policy, we introduce three properties; read, write and create.

Reading education in elementary school is being performed without connection between the curriculums and is searching for a diversified method of reading education. There are other problems in reading education such as absence of several reading education programs lack of experts with field experiences and difficulties in practicing a continuous reading education due to the emotional and disconnection between school and home. We designed a web-based reading education support system as a supplement for the reading education in which an electronic library and information about each reading-related activity can be shared. This reading education support system based on internet can connect reading education to the students everyday life. The electronic library can activate reading education by providing book management, a bulletin about the impression of a book and the information on recommended books. In addition, this electronic library can develop various reading education programs and can strengthen the relationship between school and home. This system also can make knowledge and information related activities after reading books be commonly available to all schools through the realization module, according to school and class. Therefore, various material related to reading education can be shared and statistical works are possible with the system we developed in this study.

Theorema system is built on top of Mathematica to automate deductive reasoning processes as the combination of computer algebra system and deductive system. Theorema system that was developed at RISC in Austria provides three modes based on rewriting techniques; computation, problem solving and proving. This paper shows how the computation mode of Theorema can simulate Derive part for TI-92 graphic calculators to produce TI-92 manuals. Moreover, it also describes how such manuals can be converted to web-based learning materials via Java servlet.
