This study was conducted to evaluate changes in nutritional knowledge, attitudes, behavior intention and behavior in a sample of 27 insulin dependent diabetic students participating in diabetics' camp. Nutritional knowledge related to diabetes, attitudes toward diabetes treatment and behavior intention about dietary changes were tested before and after nutrition education. Six months after nutrition education, an open ended questionnaire about their actual behavior changes was mailed to all participants and 17 of them responded. Pre-and post-testing showed that nutrition education was effective in significant changes in knowledge and in promoting positive attitudes and behavior intention. Increases of knowledge were consistently the same regardless of sex, level of education, regularity of diet, and duration of disease. Compared to male students, female students showed more positive change in knowledge, attitudes and behavior intention. It also appeared that middle school students showed more positive improvement in knowledge, attitudes and behavior than elementary and high school students. A follow-up test showed that their actual behavior changes were not squared with their behavior intention. They pointed out difficulties in having proper amount of meals and snack and the conflict with school time schedule as the major reason for discordance. These findings suggest that nutrition education for diabetics can be effective to improve their knowledge, attitudes and behavior intention and understanding about barriers to behavior change is important for better compliance to the disease.

This study aims to investigate Korean fashion-related research trends and knowledge structures on digital transformation through information-based approaches. Accordingly, we first identified the current status of the relevant research in Korean academic literature by year and journal; subsequently, we derived key research topics through network analysis, and then analyzed major research trends and knowledge structures by time. From 2010 to 2020, we collected 159 studies published on Korean academic platforms, cleansed data through Python 3.7, and measured centrality and network implementation through NodeXL 1.0.1. The results are as follows: first, related research has been actively conducted since 2016, mainly concentrated in clothing and art areas. Second, the online platform, AR/VR, appeared as the most frequently mentioned topic, and consumer psychological analysis, marketing strategy suggestion, and case analysis were used as the main research methods. Through clustering, major research contents for each sub-major of clothing were derived. Third, major subject by period was considered, which has, over time, changed from consumer-centered research to strategy suggestion, and design development research of platforms or services. This study contributes to enhancing insight into the fashion field on digital transformation, and can be used as a basic research to design research on related topics.

Expert system is a practical application part of the artificial intelligence and can be generally described as a computer-based system designed to simulate the knowledge and reasoning of a human expert, and to make that knowledge conveniently available to other people in a useful way. Expert systems consist of three major components, knowledge base, inference engine and user interface. In this paper, it is aimed to construct a prototype system to design the horizontal-typed pressure vessel. To do this, a representative artificial programming language, Turbo Prolog, was employed, and the knowledge representation was mainly done by the production rule such as "If(condition), than (action)" style and by the predicate logic. In the developed system, it was quite easy to represent the knowledge of "If(condition), then (action)"style and by the predicate logic. In the developed system, it was quite easy to represent the knowledge of "If(condition). then(action)" style and the various table-like data. It was also effective to represent the graphics. Though this expert system is by now small and incomplete, it is possible to expand it to a larger and refined system later.rger and refined system later.

The purpose of this study was to assess the adolescents' perceptions of AIDS by reviewing the research findings on adolescents' knowledge and attitudes about AIDS, and to provide basic data for the development of AIDS prevention education program. Literature for the analysis was searched by using the terms 'AIDS', 'HIV', 'Adolescent', 'Student'. Finally, 17 articles from Korea and 3 from abroad were analysed. Major conclusions were as follows: 1. For the knowledge level of AIDS, most of the adolescents knew the definition, high risk group, and infection rout of AIDS. On the contrary, the knowledge level of the treatment of AIDS was low. 2. For the attitudes toward AIDS, the level of perceived severity was high. But the level of perceived susceptibility found to be low. Middle and high school students showed more positive attitudes toward AIDS patients than college students. Attitudes toward AIDS prevention education program were positive, but taking the blood test for the detection of AIDS was negative. 3. The experience rates of AIDS Education were ranged from 13.6% to 60%. Major channel for getting AIDS information were TV, newspaper and radio. The experience rates of sexual intercourse were ranged from 4% to 48.3%. The intention of using condom was 66.7%, but the rate of condom use was 38.4%. AIDS infection rates have been increasing rapidly among teens in recent years. Therefore, It is urgent to identify the determinants affecting AIDS related perception and preventive behavior, and to develop the prevention program for AIDS.

This study aimed to investigate the actual smoking status, knowledge of oral health related to smoking, and attitude toward smoking cessation in 161 health students of the University in Jeonnam. This was done to examine the role of smoking cessation guidance as health care professionals after graduation. The collected data were analyzed using SPSS version 18.0. The significance level was α=0.05. Of those surveyed, 33.3% had previously smoked, and 30.4% were current smokers. The high school period had the highest smoking rate, at 59.2%. A daily smoking rate of 20 or more cigarettes was the highest at 30.4%. Of the respondents, 68.3% had received smoking cessation, while 10.6% said that they were encouraged by others to quit, such as friends. As a result of a correlation analysis between major satisfaction, smoking-related oral health knowledge, and attitudes toward smoking cessation, major satisfaction showed a negative correlation(r=-.394, -.337^*) with smoking-related oral health knowledge and attitude towards smoking cessation. Smoking-related oral health knowledge showed a positive correlation(r=.546^**) with attitude towards smoking cessation. As a result of a regression analysis, the knowledge of oral health related to smoking was the primary variable that affected the attitude towards smoking cessation(t=6.799, p<0.001). Based on these results, it is suggested that education on smoking cessation and the risk of smoking is delivered so that health care workers can be better prepared and educated for their future roles.

Generally mathematics is regarded as a subtle subject to grasp their true meaning. And teacher's personal conceptions of mathematics influence greatly on the teaching and learning of mathematics. More over often teachers confess their difficulties in explaining the true nature of mathematics. In this paper, applying the theory of epistemology, we tried to search factors that must be counted important when trying to understand the true nature of mathematics. As results, we identified five characteristics of mathematical knowledge such as logical reasoning, abstractive concept, mathematical representation, systematical structure, and axiomatic validation. Next, we tried to investigate math education major students' conception of mathematics using these items. To proceed this research we asked 51 students from three Universities to answer their opinion on 'What do you think is mathematics?'. Analysing their answers in the light of the above five items, we got the following facts. 1. Only 38% of the students regarded mathematics as one of the five items, which can be considered to reveal students' low concern about the basic nature of mathematics. 2. The status of students' responses to the question were greatly different among the three Universities. This shows that mathematics professors need to lead students to have concern about the true nature of mathematics.

Purpose: The purpose of this study was to investigate influencing factors in self-efficacy among college students. Methods: The sample consisted of 553 college students in C & K cities. Self-report questionnaires were used to measure the variables. In data analysis, SPSS WIN 20.0 program was utilized for descriptive statistics, Pearson's correlation coefficients, and regression analysis. Results: The mean score for Self-Efficacy was 66.62. Self-Efficacy was significantly different according to gender(t=2.076, p=.038), grade(F=11.077, p<.001), religion(F=4.666, p=.003), major(F=19.598, p<.001), economic status(F=6.570, p<.001), perceived health status(F=6.168, p<.001), and self-rated knowledge about health(F=12.936, p<.001). Multivariate analysis showed that major, self-rated knowledge about health, economic status, and perceived health status were significant predictors of self-efficacy and could explain 15.9% of total variability in this model. Conclusion: This study suggests that perceived health status and self-rated knowledge about health are significant factors in self-efficacy among college students. Therefore, the strategies of nursing intervention which improve these variables must be developed for college students.

One of the major roots of the value and power of mathematical knowledge is the belief on ‘the Pythagorian-Platonic divine mathematicity of the universe’ and the ‘pre-established harmony between mathematics and physics’. This kind of the nature of mathematical knowledge demands strongly the school mathematics to become a subject for humanity education going beyond the practical usefulness. Here, investigating the roots of the thought of mathematical education, we tried to clarify that the traditional educational ideal which has maintained the theoretical knowledge-centered mathematical education is the education of humanity, and investigate the way today's mathematical pedagogy should first turn to if it should realize this ideal.

The purpose of this study was to identify common and domain-specific cognitive characteristics of gifted students based on a hierarchical structural model of human abilities. This study is based on the premise that abilities identified by tests can appear as observable characteristics in test or school situations. Abilities proposed by major models of intelligence were reviewed in terms of their power to explain cognitive characteristics of gifted students. However, due to the lack of their explanatory power and disagreement on common and domain-specific cognitive abilities, a new hierarchical structural model was conceptualized in a unique way based on interrelationships between abilities proposed by the models. The newly established model hypothesizes a cognitive mechanism that accounts for how domain-specific knowledge is formed, as well as which abilities are common and domain-specific, how they are related functionally, and how they account for common and domain-specific cognitive characteristics of gifted students. The cognitive mechanism has important implications for our understanding of the chronically controversial concepts, 'intelligence' and 'knowledge.' Clearer definitions of what intelligence is (g or multiple), what knowledge is, and how knowledge develops ('genetic or environmental,' 'rationalistic or empiricist') may result from this model.
