We attempted to determine how adolescents' general characteristics, appearance stress, and anxiety affect adolescents' body image distortion using data from the 16th Korea Youth Risk Behavior Survey. We confirmed Body image distortion in 38.2% of the subjects, and the results of underestimated body image in 19.9% and overestimation in 18.3%. Appearance stress and anxiety were found to have an effect in both underestimate and overestimate groups. We confirmed that demographic characteristics such as gender, economic level, and academic level influence different aspects in the underestimation and overestimation groups. Therefore, we suggested that comprehensive evaluation by subdividing the subjective perception of adolescents' weight into cases of overestimation and underestimation will be an important factor in determining mental health and weight control behavior in the future.

The effect of Al₂O₃ on isokom temperatures in soda-lime glass is estimated by comparing calculated isokom temperatures using viscosity model proposed by Lakatos. Substitution of SiO₂ with Al₂O₃ by 0.5 mol% raises the isokom temperatures by 3.1, 3.3, 3.6 and 7.2℃ at the viscosity of log η = 12.3, 10, 6.6 and 1 (Pa·s), respectively. Meanwhile, replacing 0.5 mol% of CaO with Al₂O₃ raises the isokom temperatures by 1.6, 2.3, 4.1 and 17.7℃ at the viscosity of log η = 12.3, 10, 6.6 and 1 (Pa·s), respectively.

The purpose of this study is to provide the basic data for establishing a unique admissions promotion strategy for each university and to innovate the paradigm of university admissions promotion through the examples of central universities in the practice of PR promotion based on big data analysis. To this end, prior literature related to university publicity (marketing), and recognition of prospective college students who visited the university, and database data were defined and analyzed as big data. As a result, first, the preliminary studies related to college entrance exam promotion (marketing) increased dramatically in the 2000s and 2010s as part of preparing for countermeasures against population decline in school age. Responding to the need for an admissions promotion strategy to accelerate visits to prospective college students, the database data analysis result suggested the selection and concentration of entrance exam strategies based on the university's regional and academic characteristics.

It is a reality that office workers in modern society cannot overlook their appearance management for promotion in the workplace that does not fall behind in competition with others and smooth human relationships. According to this social trend, it is time to conduct an in-depth cosmetology study on the appearance management and perception of office workers, including hair styles. Therefore, this study analyzed the hair style type and preference closely by cross-analyzing the differences between groups by classifying the occupational persons of female airline crew, female soldiers, female sportsmen, female lawyers, and female nurses into age, marriage, academic background, and occupation. As result of study, it was found that different women in each occupational group had different results, such as their current hair style type and hair texture, the use of current hair styling products, and their personal preference for women's hairstyles and hair colors. This study will be used as basic data for developing new mode items that meet customer needs in the beauty marketing market and researching customer demand.

This study explored the changes in storytelling styles in high school first-year textbooks between the 2007 Revised National Curriculum of Mathematics and the 2015 Revised National Curriculum of Mathematics. The results are indicated as follows. First, the quantitative aspect of storytelling gradually increased in the textbook aligned with the 2015 Revised National Curriculum of Mathematics. Second, as for types of storytelling, the real-life connection and academic convergence types appeared most frequently, followed by mathematical history inquiry types, decision-making types, and tool utilization types. Third, storytelling appeared most frequently in 'main-body' of a lesson in terms of textbook content composition, followed by 'introduction', 'lesson materials', and 'evaluation'. This study implies that more diverse stories need to be developed; including the mathematical history inquiry types, the decision-making types and the tool use types. Textbooks should be organized not that the piecemeal storytelling presented in 'introduction' of a lesson but that a coherent story penetrates the entire unit to be utilized until the end of the lesson.

In this study, I analyzed what rhetorical citation type students most frequently used when reinforcing logic of their opinions and arguments in research papers, and compared these rhetorical types between higher and lower Korean proficiency levels of students. These 30 student papers included the following rhetorical citation types: statistics, attribution, exemplification, statement of use, establishing connections between sources, and comparing one's own findings or interpretations with other sources. Statistics was the most frequently used rhetorical citation type. In addition, the group with the highest level of Korean proficiency used citations about 8 to 11 times in their papers, and incorporated a variety of citation types including attribution, statistics, exemplification, and statement of use. Lower level students used significantly less citations and citation types. Therefore, it is necessary to raise awareness that "citations" is an important strategy to reinforce one's own logic, teach various types of citations as important research writing strategies, and prepare a more citation-focused academic writing curriculum.

Posttraumatic growth literature has been rapidly expanding in multiple academic disciplines. Purpose of this study is to examine the knowledge structure of posttraumatic growth utilizing a network analysis. Papers published between 1996 and 2018 were searched on the Web of Science, focusing on terms related to posttraumatic growth. One thousand six-hundred and fifty-nine keywords were published 6,343 times in 1,780 papers; thus, a total of 322 keywords (5,195 appearances) were selected for the final analysis. The network analysis and network visualization tool used were NodeXL and PFnet, respectively. The keywords which appeared the most frequently were "Posttraumatic growth," followed by "Posttraumatic Stress Disease," "Cancer," and "Trauma." A total of 322 nodes have been reduced to 175 nodes and divided into a total of five groups. The five groups were "Posttraumatic Growth in Cancer, Chronic/Serious Illness, and Disability," "Posttraumatic Growth-related Psychological Variables and Psychotherapy," "Posttraumatic Growth in the Context of Death," "Cognitive Mechanisms of Posttraumatic Growth," and "Vicarious Posttraumatic Growth." This study provides a systematic overview on the knowledge structure of posttraumatic growth by quantitatively network analysis.

This study is aimed to verify the impact of health literacy on communication competence in nursing students. 104 nursing students participated in this descriptive research with an online self-reported questionnaire from May 3 to 21, 2021, at a university located in G city. The data were analyzed by two-sample t-test, ANOVA and hierarchical regression with SPSS program. The score of health literacy was 48.62/66 and the communication competence was 59.60/75. More than half perceived that the average reading level of Korean adults was higher than the actual. subjective health status(β=.309, p<.001), health literacy(β=.284, p=.002) and subjective academic grade(β=.235, p=.009) had significant influence on communication competence in the nursing students(F=10.546, p<.001). The explanatory power increased 7.3% more by adding health literacy(F=10.339, p=.002). To enhance communication competence of nursing students, more systematic curriculums to improve health literacy are needed.

The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.
