This study was conducted to investigate the effects of computer attitudes such as anxiety, confidence, preference, usefulness, and computer literacy on their critical thinking ability, targeting college students at unspecified university universities. The period of data collection was from January 10, 2020 to January 17, 2020. A total of 213 people participated in the study. For data analysis, SPSS 18.0 was used for frequency analysis, Pearson correlation, x2 square, and simple regression analysis. As a result of the analysis, the difference of interests under the statistical significance level among general characteristics was Gender (x²=55.7^***, p<0.001), Age (x²=407.5^***, p<0.001), Resident (x²=127.5^***, p<0.001) Family (x²=289.4^***, p<0.001). In the simple regression analysis, computer liking (t=2.102, p<0.05) and computer use ability affected Truth seeking (t=-6.319, p<0.01), computer use ability was affecting analyticity (t=-5.630, p<0.01), computer use ability was affecting systematicity (t=-2.545, p<0.05), computer use ability was affecting maturity under statistical significance (t=-2.583, p<0.05). In conclusion, this study suggests that computer liking and computer use ability affect the sub-factor components of critical thinking disposition, truth seeking, analyticity, systematicity, and maturity, therefore the emphasis of this study is to emphasize that it is desirable to use the computer as a medium of learning based on computer literacy rather than worrying about excessive computer use.

The Criminal Law of South Korea has needed to cope with new kinds of crimes such as the fraud by use of computer efficiently in a legislative way because the society has witnessed the rapid progress of the industrialization and informatization after established in 1953. As a result, the Criminal Law revised on December 29, 1995, created the regulations of the crimes related to fraud by use of computer, work disturbance, and secret piracy by using information processing units. The regulation stipulated in Clause 347, Article 2 of Criminal Law is the most typical one against the new crimes. However, the new regulation of fraud by use of computer, established and revised to supplement the lacking parts of the current rules of the punishment of fraud, limits its object to "any benefits to property." not to "property" itself, and so cannot achieve the purpose of the revision of the law. This paper aims to suggest a new legislative measure about the object of the regulation of fraud by use of computer to solve this kind of problem efficiently.

This study was to investigate whether there are any differences in social competence by the frequency of young children's video and computer game use. Social development was categorized as peer popularity and social competence. The subjects were 215 children(118 boys, 97 girls) aged 4-6 years(M= 63.6 months, SD=6.8) from 3 kindergartens in Chung-Cheong Nam Do. The frequency of children's video and computer game use was reported by their parents. Peer popularity was rated by their classmates and social competence by their teachers with Kohn Social Competence Scale(KSCS). No significant relationship was found between game use and peer popularity. The children who played video and computer games once or twice a week got the highest score on the‘social interest and participation’But social cooperation dimension was not related with the frequency of video and computer game use but with the sex of children.

The purpose of this study is to examine middle school teachers' use of technology and problem-based learning (PBL) in their teaching practice. Factors related to teachers' use of technology and PBL are also investigated including: teachers' computer and Internet skills, feelings of preparedness to use the Internet, attitudes toward the use of web resources, pedagogical beliefs, science teaching efficacy, and the use of general teaching strategies. Twenty-seven middle school science, math, and technology teachers participated in the study. Research results describe the participants as slightly proficient in computer and Internet skills, positive toward use of web resources, and neutral on feelings of preparedness toward use of computer and the Internet. Participants also tended toward constructivist pedagogical beliefs and used various teaching strategies. They, however, reported low science teaching efficacy. Teachers' use of computers and the Internet correlated with pedagogical beliefs and feelings of preparedness toward the use of computers and the Internet. The study also found the relationships between the use of PBL and teachers' computer and internet skills, pedagogical beliefs, and the use of general teaching strategies. Also discussed are meaningful implications for teachers' professional development, especially for the programs designed to facilitate the use of web-enhanced PBL.

Several companies have migrated their existing monolithic web applications to microservice architectures. Consequently, research on the identification of microservices from monolithic web applications has been conducted. Meanwhile, the use-case model plays a crucial role in outlining the system's functionalities at a high level of abstraction, and studies have been conducted to identify microservices by utilizing this model. However, previous studies on microservice identification utilizing use-cases did not consider the components executed in the presentation layer. Unlike existing approaches, this paper proposes a technique that considers all three layers of web applications (presentation, business logic, and data access layers). Initially, the components used in the three layers of a web application are extracted by executing all the scenarios that constitute its use-cases. Thereafter, the usage rate of each component is determined for each use-case and the component is allocated to the use-case with the highest rate. Then, each use-case is realized as a microservice. To verify the proposed approach, microservice identification is performed using open-source web applications.

This study examined different individual and environmental factors that affect children's game addiction tendency. As individual variables, game user' motivation, self-control, and self-esteem were included in the analysis. As family variables, communications with mothers, parental control of children's computer use and parental internet use were examined, as school variables, school adjustment and teacher's supervision of children's computer use, and as peer variables, peer group's attitude toward computer games were used. The sample consisted of 994 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, two way ANOVA, Pearson's correlation and Hierarchical Regression. Several major results were found from the analysis. First, boys were addicted more than girls. No difference was found in the addiction tendency between the 5th graders and the 6th graders. Second, game users' motivation, that is, their interest-amusement motive, avoidance motive and aggressive motive, had a positive correlation with their game addiction tendency. However, self-control and self-esteem had a negative correlation with children's game addiction tendency. Third, problematic communications with mothers and parental control of children's computer use had a positive correlation with children's game addiction tendency. Open communications with mothers had a negative correlation with children's game addiction tendency. Fourth, school adjusaent had a negative correlation with children's game addiction tendency. And peer group's attitude towards computer games had a positive correlation with children's game addiction tendency. Fifth, low self-control, peer group's attitude towards computer games, children's interest-amusement motive, avoidance motive, aggressive motive, school lesson adjustment, parental control of children's computer use and school nile adjustment were important predicting variables of boy's game addiction tendency. Avoidance motive, low self-control, interest-amusement motive, peer group's attitude towards computer games, and parental control of children's computer use were important predicting variables of girl's game addiction tendency.

The purpose of this study is to provide basic data for school health computerization by investigating the nurse teacher's attitudes toward school health computerization. For this study, the questionnaires were given to 559 nurse teachers from 3. March to 17. March, 1995. Among them, 338 were returned and included for the analysis. The results of the study were as follows : 1. In general characteristics, the results showed average of 38.6 years in age ; and average of 11.1 years in education experience. In distribution of school, the result showed 47.0% in elementary school, 30.5% in middle school and 22.5% in high school ; 75.4% national and public school vs 26.4% private school. 2. In attitudes of computerization, the score was varied from 19 to 76 point. The attitudes was generally positive with the average of 60.23±7.63(SD) score. The respondents are willing to participate in computer education(the highest score, 3.69), they worry about electromagnetic waves by computer (the lowest score : 2.30). 3. 92.6％ of the respondents want to participate in computer education. The major reason the respondents have not yet learned computer is that they had little chance to learn. While 58.0% of them answered that they had an experience of computer use in school health works, few schools had computer in dispensary. In computer use, nurse teachers in public school have more experience than ones in private school. Word processing was the major function that the most respondents can do(62.7%). They answered that they have little knowledge of computer (84.0%). 4. Computer can be utilized in school health works as follows in order : message from school to home, reports, annual plan and statistics. 65.4% of them answered that computer can be used in 10 items of 13 items. 5. The attitudes of computerization showed differences in the following variables career, age, existence of computer in school health clinic, experience of computer use, intention to participate in computer education, computer knowledge, frequent computer use, ability of computer use, school health computerization areas, experience of computer education. Among there variables, age, existence of computer in school health clinic, intention to participate in computer education, ability of computer use, school health computerization areas showed significant explanation(28.3%) for the attitudes of computerization in multiple regression analysis The younger. the higher degree of intention, the more functions they can perform, the more school health computerization areas, and the more computers in school health clinic, the more positive attitude on school health computerization. In conclusion, to achieve the successful computerization of school health works, the positive attitudes of nurse teachers should be encourged for school health computerization. For this purpose, the chance of computer education should be given as many times as possible. And administerial as well as financial support are essential for enlarging the knowledge and ability of computer.
