Increasing sugar intake of population has become a nutritional issue in Korea. Sweet taste perception may be related to behaviors such as eating sweet food including high sugars and total sugar intake. This study aimed to evaluate objective and subjective sweet taste perception and the association among objective sweet taste perception, dietary behaviors related to eating sweet snack food including high sugar, and total sugar intake from the snacks. Participants were 261 healthy female college students (mean age: $21.0{\pm}1.6years$), who were divided into three subgroups based on oral sweet taste evaluation using a sweet taste assessment tool provided by Ministry of Food and Drug Safety: sweet-seeker group (n=139), medium sweet-seeker group (n=54), and unsweet-seeker group (n=68). There was no significant difference in weight and body mass index (BMI) among the three groups; however, the sweet-seeker group had significantly higher sweet taste preference than that of the other groups. Though more people in the sweet-seeker group thought they tended to eat sweet foods than the medium sweet-seeker and unsweet-seeker groups, over half of the sweet-seekers did not think they tended to eat sweet foods. The sweet-seeker group was more likely to eat sweet snacks such as breads, chocolate products, sugar-sweetened milk, and so on than the unsweet-seeker group. Total sugar intake from the selected sweet snacks was 44.4 g for the sweet-seeker group, 34.4 g for the medium sweet-seeker group, and 28.0 g for the unsweet-seeker group with a significant difference. These results indicated the absence of relationship between objective sweet taste perception and the obesity index; however, significant associations were detected among objective sweet taste perception, eating sweet snacks and total sugar intake from the snacks. We also found high disagreement between objective and subjective sweet taste perception of the subjects. The present study provided the novel insight that measuring objective sweet taste perception may be useful for assessing the risk of high sugar consumption and undesirable dietary behaviors.

The widespread adoption of smartphones and advancements in internet technology have notably shifted content consumption habits toward video. This research aims to dissect the nature of videos posted on YouTube, the global video-sharing platform, to understand the characteristics of both produced and preferred content. For this study, dance was chosen as a specific subject from a variety of video categories. Data on YouTube videos associated with the term "dance" was compiled over three years, from 2019 to 2021. The investigation revealed a clear distinction between the types of dance videos frequently uploaded to YouTube and those that receive a high number of views. The empirical analysis of this study indicates a viewer preference for vlogs that provide insights into the daily lives of dance students, as well as for purpose-driven videos, such as those highlighting dance exam preparations or school dance events. Notably, the vlogs that attract the most attention are typically created by dance students at the college or secondary school level, rather than by professionals. Although the study was focused on dance, its methodologies can be applied to different subjects. These insights are expected to contribute to the development of a recommendation system that aids content creators in effectively targeting their productions.

Narratively I have described interactions between two teachers performing an introduction to the engineering class with various situations such as place, teacher, student and subject. I have specifically illuminated a three-dimensional narrative inquiry space embracing the culture of the university, the college of engineering and the ABEEK(Accreditation Board of Engineering Education of Korea)program. The result of the study is as follows: First, in order to stimulate the students' motivation, the teachers have to make not only their class PowerPoint slides match the size of the classroom, but the content of the slides must be condensed with core concepts. They also should utilized some video clips to empower students' interest in the subject within their classrooms. Second, the teachers should do various class activities in the classroom. Instead of spending most of the class time with his/her explanation, it would be advantageous for the teachers to allow the students to perform a task in class. Third, the teachers should ask their students about assignments which are helping students' understanding of the subject and planning of their future. Lastly, the teachers need to design the mid-term and the final tests inducing the students' motivation. Those tests also must test students' creativity and insight of the subject. Thus, the test should consist of an interpretive exercise and an essay type of item thus reducing the multiple choice types of items. There are several limitations to the study. First it is difficult to generalize what we found here because it is a case study. Second, we could not study in depth the effect of the interaction between the two teachers who were performing the introduction to the engineering course during the academic semester. Third, this study just probed into the difficulties of teaching the course. Hence, we have to understand more by focusing on each issue such as adapting to a new learning environment as a student from abroad, a practical experience boosting the students' interest in the introduction to the engineering course, also a practical experience on process based learning-versus result based learning, and an effective management of the student team presentation etc.

The purpose of this study is to measure the relative importance of the factors that affect school to work transition that food service-related majors and workers recognize. To this end, this study composed such factors into a second hierarchy level of individual background, educational background, and preparation effort to enter labor market. The study made us of the analytic hierarchy process(AHP), which calculates the importance of each factor through the relative evaluation of each factor in the hierarchy. The results of analysis are as follows. First, in the second hierarchy level, effort to enter the labor market exhibited the highest relative importance. In the case of four-year college students, educational background had the highest relative importance. Second, in case of third hierarchy level factors relating to personal background, gender had the highest relative importance. As for educational background, the type of college had the highest relative importance. As to the effort to enter labor market, overseas working experience while in college and job searching channels had high relative importance, while vocational training experience had the lowest relative importance. Third, the analysis result of complex weighted value showed that the type of college had the highest complex weighted value. In future studies, the type of businesses and business conditions in the food service industry should be subdivided for an analysis of influential factors, and, based on this, customized career guidance should be made for specific career paths of each student.

This study aimed to investigate beginner-level learners' use of translators in L2 writing, and shed light on its validity in writing performance through their responses on the necessity, reliability and limitation of machine translation. 117 university students from beginner-level L2 writing classes participated in the survey. Additionally, 11 of them were interviewed about their answers. The survey and interview data revealed varying viewpoints such as reliability and effects as well as reasons for choosing translator-assisted writing. The vast majority(76.1%) used web-based machine translators for their writing activities, and employed various strategies to help their insufficient L2 skills and to increase their motivation and confidence. On the other hand, they exhibited its detrimental effects including it could lead to plagiarism, and interfere with the learning process unless they post-edited the given translation. However, translators were viewed as a new, efficient, and valid educational tool for effective and successful L2 writing.

There were no significant differences in lumbar spine, femur and forearm BMD values among the three groups. However, the forearm BMD in the moderate activity group and low activity group groups were significantly different when the dominant hand and non-dominant hand were compared (p<0.05). In addition, walking, a form of weight-bearing exercise, is strongly recommended to improve bone health and prevent osteopenia in adolescents. Therefore we conclude that high amounts of daily walking could enhance the non-dominant hand BMD even though anatomically, the forearm bone is not a gravitational burden-bearing bone.

Internet shopping provides convenience to consumers, however, in recent years the consumer's return rate and return-related disputes continue to increase. This article examines the characteristics of return behavior through return experiences of internet clothing purchases. For an empirical study, questionnaires were handed out to 317 undergraduate male and female students, in which the results had been used for data analysis. Data were analyzed through SPSS 12.0 software, descriptive statistics, factor analysis, t-test, ANDVA analysis, Duncan test, and $x^2-test$. The results are the following: The analysis of consumers' return factor for clothes in Internet shopping showed there are five factors: product and quality, delivery, impulse buying, change of mind, and service. There is a significant difference in product quality of return factors depending on the availability of the return experience. Thus, consumers with return experience showed more return tendency owing to product quality factor than consumers without return experience. The availability of consumer's return experience was significantly related to information search. Consumers with return experience showed more consistent information search than consumers without return experience. There were significant differences in perceived risks depending on the availability and degree of consumer's return experience. In other words, consumers with return experience perceived more account related risk than consumers without return experience. Moreover, the more return experience the consumer has, the more risks consumers perceived in product performance.

The purpose of this study was to verify the mediating effects on self-regulated learning ability and sense of community in the relationship between parents' neglect and children's academic achievement. The subjects used in this study were 2,218 6th grade elementary school students from the third wave sample of the 2012 Korean Children and Youth Panel Survey (KCYPS). For data analysis, the three-step mediated regression analysis by Baron and Kenny (1986) was performed and the Sobel test was carried out in order to verify the effectiveness of mediation effects. The main results of the present study were as follows. First, the self-regulated learning ability and sub-component factors of achievement value, mastery goal orientation, behavioral control, academic time-management revealed to have a partial mediation effect in the relationship between parents' neglect and children's academic achievement. Second, the sense of community also showed to have a partial mediation effect on the relationship between parents' neglect and children's academic achievement. The findings of this study provide a viewpoint to deeply observe the problem of parents' neglect in connection with children's self-regulated learning ability and sense of community, and can be used as practical data to develop various programs for the benefit of improving children's academic achievement.
