The purpose of this study was to identify whether the elementary school students force conceptions may influence on designing tools experiments. Four questions with multiple choices and reasons for those choices were asked to identify scientific/alternative force conception. Also four tasks for tools experiments matched to each force conceptions were developed into open questions in hypothesizing. controlling variables and methods of experiments. Forty elementary students were selected from 4 classes in sixth grade of a school in Daegu city. The major findings of this study were that the types of force conceptions can be classified into scientific and alternative conceptions. The patterns of designing experiments could be identified with types of hypothesis, controlling variables and methods of experiments in each four tools experiments. But students those who had scientific force conception did not better in hypothesis, methods of controlling variables and results for simple experiment than those who had alternative force conceptions. These results imply that students' force conception did not influence on designing tools experiments. The assumption that scientific conception could improve designing experiments was not guaranteed by this results.

This study was conducted structural model analysis focusing on the factors influencing UHDTV service usage. The perceived quality, innovativeness, price sensitivity are adopted as independent variables and perceived usefulness, perceived easy use are adopted as intervening variables. Especially symbolism used it as a control variable. As a result of the analysis by PLS, the influence coefficient of perceived quality was significantly higher than other variables. However, the combined effect of symbolism and perceived quality has a negative effect on perceived usefulness, and the more the users consider the symbolism of UHDTV usage, the more negative the evaluation of UHD quality and usefulness. With the launch of the terrestrial UHDTV service in May 2017, the most important issue is the production and distribution of high-quality content that users want.

Unlike previous studies that focused on the diversity of YouTube content, this study tried to identify factors affecting users' satisfaction with the YouTube recommendation system. Specifically, by adding content preference suitability and privacy concerns to the technology acceptance model, we empirically analyzed how these variables affect user's satisfaction of the YouTube AI recommendation system. For this purpose, asurvey was conducted on college students in their 20s and 30s, and the main research results are as follows. First, in the respondents of this study, playfulness and usefulness, which are major variables of the technology acceptance model, appeared as significant factors affecting the satisfaction of the YouTube AI recommendation system, whereas the effect of ease to use was not found. Second, content preference suitability was found to affect the satisfaction with AI recommendation system, but privacy concerns did not affect the satisfaction with YouTube AI recommendation system. Based on these research results, the implications of the study and the directions for future studies were suggested.

The purpose of this study is to verify antecedent variables that positively influence behavioural engagement during school engagement, which is critical to adolescent socialization. The antecedent variable was categorized into the personal characteristics of adolescents who are the main agents of socialization and peer support and teacher support, which can be called social support at school sites. Individual characteristics include strength recognition, strength utilization, and learning goal orientation, and, peer supports include the supports for personality strength and academy, and, teacher supports include the supports for personality strength and perspective change. For this study, a survey was conducted on 539 high school students nationwide, collected data, 33 of them were removed, and 506 data were analyzed. Analysis shows that only learning goal orientation set as a sub-factor of individual characteristics has a static significant effect on behavioral engagement. Finally, based on the findings, we discuss the implications, limitations, and future research tasks of the study.

The purpose of this study was to examine whether gifted achievers and gifted underachievers differ in their learning strategies, motivation, beliefs in ability, and problem solving patterns. The sample for the study consisted of 68 gifted achievers and 34 gifted underachievers who were in 5th and 6th grades in elementary schools in the metropolitan area. Gifted achievers and gifted underachievers showed statistically significant differences in all aspects using the independent sample t-test. In addition, the discriminant analysis correctly classified over 77.5% of the sample as either gifted achievers or gifted underachievers using the variables used in the study, indicating factors related to learning strategies can be effective measures to identify gifted achievers and underachievers. Especially, extrinsic motivation and problem solving patterns were the most discriminant factors in these two groups. The implications of the study related to the identification and education of the gifted underachievers were discussed in depth.

This study is to know the relations between self-efficacy and a factor to decide their major for beautician students. with questionnaires from 180 beautician students in Seoul, we could see a significant result with p < .05 from self-confidence and self-control efficacy of self-efficacy according to major satisfaction, a high level of significant result with p < .01 from level of difficulty of assignment, a significant result with p < .05 from information collect of career-deciding factor, and a greatly high level with p < .001 from goal setting, career planning and self-rating. As to verify the correlation of sub variables between self-efficacy and career-deciding factor, I analyzed it. Then I found that every variables except problem solve in self-confidence of self-efficacy variables showed a significant result and every variables between sub-variables and others in career-deciding factor showed a significant outcome. In conclusion, it is considered that self-efficacy resulting from major satisfaction plays a critical role in students career decision-making and that students self-efficacy and career deciding factors are corelated, given the meaningful outcome from them.

This study aimed to identify the correlation between internal/external motive, academic failure (emotion, behavior, task preference), depression (depressive emotion, behavioral disorder, loss of interest, self-degradation and physiological symptom), and academic efficacy of elementary school students with underachievement basic learning, and discover the influential variables on internal/external motive, targeting 56 elementary school students with underachievement in third and fifth grade of 10 elementary schools in G metropolitan city. The research conducted T-test to figure out the difference between the children with underachievement by year and carried out theregression analysis to identify the predictors of self-determination motives. First, there was a difference between the third and fifth graders in terms of the external motives. Second, the influential variables for external motives of children with underachievement included depressive emotion, loss of interest and physiological symptom. Therefore, as more third graders with underachievement study under the external motives compared to the fifth graders, it is concluded necessary to adopt a program to reduce the variables for depression that influence the external motives.

The syllable frequency effect is defined as the inhibitory effect that words starting with high frequency syllable generate a longer lexical decision latency and a larger error rate than words starting with low frequency syllable do. Researchers agree that the reason of the inhibitory effect is the interference from syllable neighbors sharing a target's first syllable at the lexical level and the degree of the interference effect correlates with the number of syllable neighbors or stronger syllable neighbors which have a higher word frequency. However, although the syllable frequency can be classified as the syllable type and token frequency, previous studies in visual word recognition have used the syllable frequency without the classification. Recently Conrad, Carreiras, & Jacobs (2008) demonstrated that the syllable type frequency might reflect a sub-lexical processing level including matching from letters to syllables and the syllable token frequency might reflect competitions between a target and higher frequency words of syllable neighbors in the whole word lexical processing level. Therefore, the present study investigated their proposals using word naming tasks. Generally word naming tasks are more sensitive to sub-lexical processing. Thus, the present study expected a facilitative effect of high syllable type frequency and a null effect of high syllable token frequency. In Experiment 1, words starting with high syllable type frequency generated a faster naming latency than words starting with low syllable type frequency with holding syllable token frequency of them. In Experiment 2, high syllable token frequency also created a shorter naming time than low syllable token frequency with holding their syllable type frequency. For that reason, we rejected the propose of Conrad et al. and suggested that both type and token syllable frequency could relate to the sub-lexical processing.
