The learning analytics dashboard (LAD) is a supporting tool for teaching and learning in its personalized, automatic, and visual aspects. While several studies have focused on the effect of using dashboard on learning achievement, there is a research gap concerning the impacts of learners' characteristics on it. Accordingly, this study attempted to verify the differences in learning achievement depending on learning motivation level (high vs. low) and dashboard intervention (use vs. non-use). The final participants were 231 university students enrolled in a basic statistics course. As a research design, a 2 × 2 factorial design was employed. The results showed that learning achievement varied with dashboard intervention and the interaction effect was significant between learning motivation and dashboard intervention. The results imply that the impact of LAD may vary depending on learner characteristics. Consequently, this study suggests that the dashboard interventions should be offered after careful consideration of individual students' differences, particularly their learning motivation.

Objective: This study examines the generational characteristics and job perceptions of early childhood teachers from Generations X, M, and Z. Methods: Seventeen teachers were selected based on their career and the types of childcare centers they worked in. Focus group interviews explored their job perceptions, teaching methods, career intentions, and strategies to attract future teachers. Results: The results revealed both positive and negative generational perceptions, with Generation X and M noted for diverse job experiences and Generation Z for digital skills. Individual differences were also observed. All generations reported low job satisfaction due to societal perceptions and environmental changes. Many teachers plan to change jobs. The study suggests utilizing generational strengths for peer support to enhance professional development. Conclusion/Implications: Furthermore, improvements in societal perception and treatment of childcare jobs are needed to attract future teachers. The findings suggest implications for enhanced intergenerational communication and collaboration in the childcare field.

This study focused on individual differences in social support among older adults. The purposes of this study were to investigate sex and age group differences in social support and to examine the effects of intergenerational social support on life satisfaction among the rural elderly. Data were from 545 elderly over 60 years of age living separately from adult children in the rural area. With regard to sex differences in support exchanges, no significant differences were found in support-giving and support-receiving. Men reported giving more financial support to children than women, while women reported receiving more financial support from children than men. With regard to age group differences in support exchanges, there was less support-giving in older age group. Older parents in their 60s reported giving more financial, instrumental, and emotional support and receiving less financial support than the group of age 70＋ Regression analyses showed that life satisfaction of both men and women was affected by support size and the frequency of contact with children. Giving financial and instrumental support was significantly associated with life satisfaction of men, but giving and receiving each type of social support had no effects on life satisfaction of women. Life satisfaction of parents in their 60s was found to be positively associated with support size, giving financial support and receiving emotional support, and negatively associated with giving instrumental support. In the group of age 70＋, the frequency of contact with adult children and giving financial support had positive influences on life satisfaction.

The purpose of this study was to examine the relationship between academic personality types and academic achievement in an effort to seek teaching and learning strategies geared toward improving the academic achievement of students. The subjects in this study were 400 dental hygiene students who were randomly selected from three-year colleges in Gyeonggi Province. Their academic personality types and academic achievement were investigated, and the findings of the study were as follows: 1. As for the academic personality types of the subjects, the inquiry-oriented type was most dominant, and the ideal-oriented one was least common. 2. In regard to differences in academic personality types according to academic year, the inquiry-oriented type was most common in every academic year, and there were statistically significant differences(p<.05). 3. As to differences in academic personality types according to academic achievement, the best academic achievement was found in the norm-oriented type, and there were statistically significant differences(p<.05). 4. Concerning differences among the subjects in academic satisfaction according to academic personality types, there were no statistically significant differences(p>.05). When the above-mentioned findings of the study were pieced together, the academic achievement of the subjects varied with their academic personality types, and it's consequently necessary to make an effort to apply different teaching methods and learning methods according to their preferences. As there are individual variances among students in achievement goal, preferred learning method and experience though they study in the same space with different learning methods, the development of student guidance programs tailored to academic personality types seems necessary.

This study would review how important to define emotional intelligence could be in measuring individual differences in emotional experience. For this purpose, the definitions of emotion, built by psychological theorists, would first reviewed, in connection to the newly developed techniques in the area of emotional engineering. Comparing peripheral theories of emotion and cognitive appraisal theories, the multi-facets of emotional experience would be illustrated and it would discussed what these facets mean to predict emotional health of individuals.

The causative role of polycyclic aromatic hydrocarbons (PAH) in human carcinogenesis is undisputed. Measurements of PAH-DNA adduct levels in easily accessible white blood cells therefore represent useful early endpoints in exposure intervention of chemoprevention studies. The successful applicability of DNA adducts as early endpoints depends on several criteria:i.adduct levels in easily accessible surrogate tissues should reflect adduct levels in target-tissues, ii. toxicokinetics and the temporal relevance should be properly defined.iii. sources of inter- and intra-individual variability must be known and controllable, and finally iv. adduct analyses must have advantages as compared to other markers of PAH-exposure. In general, higher DNA adduct levels or a higher proportion of subjects with detectable DNA adduct levels were found in exposed individuals as compared with non-exposed subjects, but saturation may occur at high exposures. Furthermore, DNA adduct levels varied according to changes in exposure, for example smoking cessation resulted in lower DNA adduct levels and adduct levels paralleled seasonal variations of air-pollution. Intra-individual variation during continuous exposure was low over a short period of time (weeks), but varied significantly when longer time periods (months) were investigated. Inter-individual variation is currently only partly explained by genetic polymorphisms in genes involved in PAH-metabolism and deserves further investigation. DNA adduct measurement may have three advantages over traditional exposure assessment: i. they can smooth the extreme variability in exposure which is typical for environmental toxicants and may integrate exposure over a longer period of time. Therefore, DNA adduct assessment may reduce the monitoring effort. ii. Biological monitoring of DNA adducts accounts for all exposure routes. iii. DNA adducts may account for inter-individual differences in uptake, elimination, distribution, metabolism and repair amongst exposed individuals. In conclusion, there is now a sufficiently large scientific basis to justify the application of DNA adduct measurement as biomarkers in exposure assessment and intervention studies. Their use in risk-assessment, however, requires further investigation.

This study was designed to evaluate the effect of the individual nutrition education for type 2 diabetes who participate the diabetes buffet. The subjects were 66 patients and divided into education (n=34) and control groups (n=32). The mean age of education and control groups were 59.8 and 56.6 years old, respectively. There were no differences in age and body mass index (BMI) between two groups. Initial glycosylated hemoglobin (HbA1c), post prandial plasma glucose (PP2), total plasma cholesterol, and blood pressure were not different between two groups. But fasting blood sugar (FBS) was higher in education group than in control group. On completion of the study, the education group showed significant decreases in body weight, BMI, FBS and PP2, however, the control group showed no changes in body weight, BMI and PP2, and showed a significant increase in FBS. Initial calorie and protein intakes of the education group did not meet the prescribed amount, however, mineral and vitamin intakes were higher than estimated average requirement (EAR). By the end of study, calorie and protein intakes were significantly increased to meet the prescription. In order to evaluate the effect of diet education, awareness of calorie requirement was used as an index of understanding diet prescription. The degree of awareness of calorie requirement was dependent on age: younger patients showed higher awareness than older subjects. The subject who showed better understanding of diet prescription showed lower levels of HbA1c, FBS, and PP2 at the end of the experiment period. The results of this study clearly show that individual diabetes diet education is effective to make the patient understand their diet prescription, and is effective to control body weight and blood sugar level. Awareness of calorie requirement could be used as an index of understanding of prescribed diet. Since age is an important variable to determine the awareness of calorie requirement, different strategies of nutrition education should be developed for different age groups, especially patients over 70 years old.
