  • The purpose of this study was to verify the moderating effect of parental learning involvement in the effect of adolescents' time management ability on face-to-face and non-face-to-face learning flow. The participants were 363 middle and high school adolescents, and data were collected through an online survey. The main statistical analysis methods were ANOVA, correlation analysis, and regression analysis. The major findings were as follows. First, learning flow was significantly higher in the face-to-face class than in the non-face-to-face class. Second, there was a statistically significant positive correlation among time management ability, parental involvement in learning, and learning flow. Third, in the effect of time management ability on face-to-face learning flow, the moderating effect of parental learning involvement was statistically significant. Fourth, in the effect of time management ability on non-face-to-face learning flow, the moderating effect of parental learning involvement was statistically significant. In other words, the higher the positive parental involvement in learning, the stronger the effect of adolescents' time management ability on learning flow. Finally, the importance of positive parental involvement for the improvement of adolescents' learning flow and methods of enhancing time management ability were discussed.

  • Purpose: This study aimed to assess the weight fluctuations in college students during the coronavirus disease 2019 (COVID-19) pandemic and identify lifestyle and dietary changes related to weight gain. Methods: An online survey was conducted on 270 college students from September 22 to October 26, 2021. A logistic regression analysis was performed to analyze the relationship of weight gain with the general characteristics, lifestyle, and dietary changes of the students. Results: Among the respondents, 42.9% of men and 44.7% of women reported weight gain. The main reasons given for weight gain were reduced activities due to restrictions during lockdown and diet changes, mainly relating to delivered or fast foods. Among the general characteristics and lifestyle factors poor perceived health (odds ratio [OR], 3.97, 95% confidence interval [CI], 1.98-7.96) and being underweight (OR, 0.19, 95% CI, 0.05-0.83) were significantly associated with weight gain. With respect to the diet, increased frequency of eating breakfasts (OR, 4.44, 95% CI, 1.76-11.21), decreased frequency of eating snacks (OR, 0.35, 95% CI, 0.16-0.77), decreased frequency of fruit intake (OR, 3.0, 95% CI, 1.32-6.80), increased frequency of carbonated and sweetened beverage intake (OR, 2.74, 95% CI, 1.26-5.99) and increased frequency of fast food consumption (OR, 2.32, 95% CI, 1.14-4.70) were significantly associated with weight gain. Conclusion: The COVID-19 pandemic affected weight gain and caused lifestyle and dietary changes. Specific health and nutrition management plans should be prepared for handling future epidemics of infectious diseases based on the results of surveys conducted on larger sample size.

  • Background: To date, various genotypes of infectious bronchitis virus (IBV) have co-circulated and in Korea, GI-15 and GI-19 lineages were prevailing. The spike protein, particularly S1 subunit, is responsible for receptor binding, contains hypervariable regions and is also responsible for the emerging of novel variants. Objective: This study aims to investigate the putative major amino acid substitutions for the variants in GI-19. Methods: The S1 sequence data of IBV isolated from 1986 to 2021 in Korea (n = 188) were analyzed. Sequence alignments were carried out using Multiple alignment using Fast Fourier Transform of Geneious prime. The phylogenetic tree was generated using MEGA-11 (ver. 11.0.10) and Bayesian analysis was performed by BEAST v1.10.4. Selective pressure was analyzed via online server Datamonkey. Highlights and visualization of putative critical amino acid were conducted by using PyMol software (version 2.3). Results: Most (93.5%) belonged to the GI-19 lineage in Korea, and the GI-19 lineage was further divided into seven subgroups: KM91-like (Clade A and B), K40/09-like, QX-like (I-IV). Positive selection was identified at nine and six residues in S1 for KM91-like and QX-like IBVs, respectively. In addition, several positive selection sites of S1-NTD were indicated to have mutations at common locations even when new clades were generated. They were all located on the lateral surface of the quaternary structure of the S1 subunits in close proximity to the receptor-binding motif (RBM), putative RBM motif and neutralizing antigenic sites in S1. Conclusions: Our results suggest RBM surrounding sites in the S1 subunit of IBV are highly susceptible to mutation by selective pressure during evolution.

  • The previous researches of gambling have been rather focused on the legal gambling industry and gambling addiction and ignored the issue of illegal gambling. But, illegal gambling in Korea has been continuously growing in its volume and the numbers of the relevant mental and social problems such as gambling addiction, crimes, suicides, and etc. have been increasing rapidly. The present study investigated the psychological characteristics of illegal gamblers with comparing gamblers who never experienced illegal gambling (NE), who experienced illegal gambling but participate mainly in legal gambling (EIG), and who participate mainly in illegal gambling (MIG). 1317 NEs, 177 EIGs, and 37 MIGs were recruited and completed an online survey that measured individual dispositions (risk-taking tendency, regulatory focus, locus of control), attitudes towards gambling regulations, misconception of illegal gambling, motives (monetary, excitement, socialization), and emotions. First, EIGs and MIGs, compared to NEs, preferred risk-taking, and EIGs were more promotion focused than NEs. Also, EIGs perceived illegal gambling as less illegal and tended to hold more misconceptions about illegal gambling, compared to NEs. Furthermore, EIGs and MIGs had stronger monetary and excitement motivation than NEs. Finally, MIGs were more likely to feel anxious than other groups. Focusing on the illegality of gambling, the characteristics of illegal gamblers are discussed and political implication on illegal gambling is suggested.

  • Negative experience related to work-family multiple roles has been associated with internalizing problems in mothers. In particular, employed mothers with preschool children report high degree of stress. As such, the need to examine potential factors that may explain and alleviate such difficulties has been emphasized. The purpose of this study was thus to examine the mediating effect of sociotropy on the relationship between negative work-family multiple roles and internalizing problems in employed mothers with preschool children. The Negative Experience of Work-Family Multiple Roles Scale, Adult Self Report (ASR) Scale, and Personal Style Inventory-II (PSI-II), were completed by 208 employed mothers with preschool children through an online survey. The results indicated that the direct effect of negative experience of work-family multiple roles on internalizing problems was statistically significant and the indirect effect of sociotropy in this relationship was significant. These findings suggest that sociotropy in employed mothers may indirectly explain internalizing problems related to multiple roles. The implications of sociotropy in negative experience of work-family multiple roles and internalizing problems are discussed.

  • Wheat was brought to solve food scarcity with aid from the United States caused by the Korean War. The Korean government launched a campaign to encourage mixed rice and wheat meals due to shortage of rice production in the 1960s, Wheat consumption began in earnest. However, it is difficult to rebuild the domestic wheat production base devastated by the Korean War with the technology at the time. Thus, wheat was mainly consumed from imported in the past. Since then, as wheat consumption has increased due to westernization and diversification of dietary life, wheat became the second staple grain in Korea. In this situation, the government enacted the Wheat Industry Promotion Act to create a basis for sustainable production and consumption of wheat in Korea. This study sought to improve the self-sufficiency of domestic wheat by examining the possibility of using "Ariheuk", a variety of new Korean wheat, as a rice supplement in the same context as the govemment's policy. Wheat has been used as a raw material for the processed food, such as noodles and bread. However, we approached it by using whole wheat as a nutritional grain. Participants were recruited from the agri-food consumer panel conducted by Rural Development Administration. We set a final sample of 525 consumer panels based on the age of census household heads. The experiment was conducted in such a way that participants cooked and ate 100% rice meal and rice containing 20% whole wheat meal. Participants completed the sensory evaluation questionnaire with online. For this experiment, all participants were given same whole wheat product. The sensory evaluation questionnaire consisted of color, glossiness, stickiness, aroma, chewing, sweetness, nuttiness, chewiness, softness, bursting, flavor, texture and swallowability. The sensory evaluation results were analyzed by giving -3 points to +3 points. The former points were given to the response that 100% rice meal is very superior to the response that rice containing 20% whole wheat meal. The latter points were given vice versa. Zero point was given to the response that they are similar each other. As a result, rice with 20% whole wheat meal was better than 100% rice meal in terms of color, aroma, chewiness, bursting and flavor. In case of sweetness and glossiness, there didn't exist significantly different. On the other hands, 100% rice meal was better in terms of softness and swallowability. As a result of ANOVA by age groups, from 30s or younger to 60s or more, there was significant difference among the groups in terms of color, chewiness and bursting. As a result of post-hoc analysis with Duncan's multiple range test (p < 0.05), 50s were evaluated to be significantly superior in color, chewiness and bursting compared to other age groups. In conclusion, it is appropriate to use whole wheat as a supplement to rice in order to improve the self-sufficiency of domestic wheat. As a strategy to promote domestic wheat consumption, in case of Ariheuk, it is necessary to provide an experience through whole wheat tasting and to establish a marketing strategy segmented by age groups.

  • This paper aims to develop a map for optimized class space using ZEP among the metaverse platforms. As a research method, the classroom space was organized so that the subject of learning became a learner, and the classroom space was modified and supplemented to optimize while being applied to elementary school computer classes. The contents of the study investigated learners' prior perception of metaverse, and compared and analyzed the advantages and disadvantages of the metaverse platform. In addition, the map was designed by reflecting the results of the survey, and after applying the map to the class, necessary APIs and apps were installed to supplement it. As a result, the learner became the subject of learning in the metaverse space, freely identified the space, and actively participated in the class. In particular, we found that students who were passive offline and those who had a low participation rate due to lack of skills participated more actively. In particular, students who were passive offline or whose participation was low due to lack of skills participated more actively. If API and JavaScript programs are added to collect log data of learners for learning analysis, real-time feedback is possible for learners, and learner feedback is possible for instructors with statistical data. If this is possible, the metaverse space can fully expect the role of a learning assistant for learners and a teaching assistant for instructors.

  • Objective : This study sought to explore occupational therapy students' awareness of Developmental Rehabilitation Services (DRSs) and the certification of Sensory Developmental Rehabilitation Service Providers (SDRSPs). Moreover, it also aimed to examine the differences in students' awareness based on general characteristics. The findings were intended to provide a foundation for research on sensory developmental rehabilitation. Methods : An online survey was conducted among 199 occupational therapy students nationwide from October 4 to November 5, 2022. Frequency analysis was used to assess the general characteristics and additional items. Both descriptive statistics and frequency analysis were employed to assess the students' awareness of DRSs and SDRSP certification. Any differences in the students' awareness based on their general characteristics were examined using t-tests and an analysis of variance. Results : The students' awareness of DRSs was moderate (4.50 ± 2.40), while their awareness of SDRSP certification was also moderate (4.22 ± 2.55). The awareness of DRSs varied significantly based on the students' academic year and child-related practice experience. Similarly, the awareness of SDRSP certification differed significantly based on the students' academic program, academic year, recognition by the related department, and child-related practice experience. Conclusion : The occupational therapy students expressed a strong intention to provide DRSs and become certified as SDRSPs. However, their awareness levels were moderate. These findings emphasize the importance of educational efforts and the provision of relevant information about DRSs and SDRSP certification in universities to foster the development of competent SDRSPs.

  • This study analyzed the awareness and actual condition on metaverse utilization in education for design major students. An online survey was conducted for 14 days from May 10 to 23, 2023, targeting 120 students majoring in design at D University. The evaluation method of the questionnaire was a nominal scale and a 5-point scale, and the questionnaire results were analyzed through SPSS 29.0. First, it is necessary to sufficiently share the advantages of metaverse utilization in education with students, and to provide basic literacy programs utilizing the characteristics of metaverse and supporting class activities. Second, students' response will be higher in studio classes where practical training is conducted rather than information delivery or understanding-oriented lectures. Third, in order for the metaverse to become a means of education in the digital transformation era rather than just a temporarily medium in COVID-19 era, specific and systematic design education programs reflecting the characteristics of the metaverse need to be continuously developed. In addition, it is important for instructors to actively review the use of the metaverse and search for various ways to utilize it.
