최근 현대인의 영양불균형이 점점 심화됨에 따라 영양결핍과 비만의 위험도가 점점 증가하고 있다. 이에 따라 건강기능식품에 대한 관심이 증가하여 일반인들의 건강기능식품 소비가 증가하고 있지만, 적정섭취량에 비해 영양소를 과도하게 섭취 중이거나 영양제를 먹지만 정작 필요한 영양소를 섭취하지 못하는 경우가 빈번히 나타나고 있다. 이러한 문제를 해소하고자 본 논문에서는 7 일간 사용자가 섭취한 식단을 기반으로 부족한 영양소를 수치상으로 계산하여 개인 맞춤 영양제를 추천하는 시스템을 제안한다.

The purpose of this study was to examine university students' understanding of the nature of science, an aspect of scientific literacy, which is the goal of modern science education. To accomplish this, the differences and similarities by gender and major. on college students' understanding of the nature of science were investigated. 'Understanding of the Nature of Science' developed by Lee (2003) was implemented for this study. The instrument has three sub-scales; a scientific world view, scientific inquiry, and scientific enterprise. The instrument is only expected to give, and provides meaningful information on student understanding of the nature of science. A total of 120 college students, majoring in science education, liberal arts, and physical exercise participated in this study. Science education major students were verified to have a better understanding of the nature of science followed by liberal arts students and then physical exercise students. Moreover, men revealed slightly more comprehension that of women. More than 80% of students, majoring in science education, answered 11 out of 23 questions, approximately 50%. In the area of scientific inquiry, both science education and liberal arts students showed more comprehension that those in physical exercise. All participants showed relatively lower comprehension of the definition of scientific contribution than other subjects, but displayed a greater comprehension of the ethics of science. On the other hand, most students have relatively low apprehension in the contribution of science, while higher apprehension in the ethics of science.

The purpose of this study is to present the basic data needed to improve the arts, music, and physical education provided by local child care centers based on an investigation of the current status of and satisfaction with the education. The subjects of this study were 17 local child care centers in Gyeonggi-do, South Korea, and the situation of the arts, music, and physical education programs operated from 2014 to 2016 were examined. In addition, 419 children who received the education were surveyed to evaluate their level of satisfaction. The results of this study are as follows. As regards the status of the arts education from 2014 to 2016, it was observed that three of the 17 local child care centers did not have any arts, music or physical education at all, while six of them continuously implemented all three of these programs during this period of time. Two and six of the 17 institutes had arts, music, and physical education programs for two years and one year, respectively. All of the teachers who ran the arts and music education programs of the 17 institutes were arts and music majors who were certified teachers of the liberal arts. However, the physical education programs were run as volunteer activities by college students majoring in physical education. The survey on the level of satisfaction of the children who participated in the arts, music, and physical education programs showed that they were helpful for the overall life experience of the children and that they were more helpful for the boys than for the girls. The level of satisfaction with the education was high for most of the students who participated in the programs, however the boys were more satisfied than the girls. When asked whether they would participate in the arts, music, and physical education programs again, most of the respondents answered that they would do so. The boys were more likely to participate again than the girls. Based on this study, in order to enhance the creativity and personality education of the children using the local child care centers, higher quality education is needed. Arts and music education can be used to help children to learn to communicate smoothly with their friends. In addition, it seems to be necessary to enhance the education by setting goals that are suitable for its purpose, in order to provide creative arts and music education that contributes to the physical health and emotional stability of the children.

This research presented development contents for application of realistic content approach study that can experience T-ball sports used in regular physical education classes at indoor space with screen. The scope of application can be used for ball sports training in virtual reality sports room of elementary and junior high schools. The approach process presents an appropriate approach system for sustainable training education which is to improve T-ball sports training to target users through consultation-based collaboration with sports experts and T-ball leaders, focusing on basic training content of T-ball textbooks. In other words, the training mode was designed to induce immersion in T-ball sports classes and provide natural basic training for students at elementary schools rather than simply experience-based realistic content. The developed training content provided basic attack training according to weekly differentiated curriculum, and the approach process of training mode by difficulty level was presented to allow the user to improve the training by the degree of difficulty. In addition, the match mode approach process that reflects the game rules of T-ball sports was presented. This study can be presented as a reference production case that can be used to improve basic training and physical exercise of ball sports for industries related to development of realistic content.

This study was conducted on the assumption that bone age would be more effective when it comes to physique and physical fitness assessment for adolescents, and the purpose of this study was to identify the differences in physique and physical fitness for students in their adolescence through bone age and chronological age in order to contribute to the well-balanced physique and physical fitness development in adolescents and the health improvement in students. Total 874 adolescents(483 males, 391 females) aged 11~16 were selected as subjects out of the total population of 1100 adolescents aged 6~16 based on the PAPS(Physical Activity Promotion System) and age standards of the TW3 method; and skeletal maturation, which symbolize the indicators of biological maturation, were evaluated by using the TW3(Tanner-Whitehouse 3) method after hand-wrist radiographs, and birth date was used for chronological age. A stadiometer and InBody 270 (Biospace, Korea) were used to measure 2 components in physique. A total of 7 components in physical fitness, which included muscular strength, muscular endurance, flexibility, power, cardiovascular endurance, balance, agility, were measured as well. A independent samples t-test was conducted for data processing using SPSS 25.0, and the significance level was set at p< .05. The study results are as follows. First, bone age and chronological age used for physique comparison in males aged 11 and 12, height and weight showed significant difference; in males aged 13, weight showed signicant difference. Weight and height in females aged 11, and height in females aged 12 showed significant difference. Second, bone age and chronological age used for physical fitness comparison in males aged 11, muscular strength, power, flexibility, cardiovascular endurance showed significant difference; in males aged 12, muscular strength. power, cardiovascular endurance; in males aged 13, flexibility showed significant difference. Muscular strength, power, flexibility, muscular endurance, cardiovascular endurance in females aged 11, and flexibility in females aged 14 showed significant difference. As a result, this study concluded that in a period of rapid skeletal growth, evaluating physique and physical fitness based on bone age is more accurate than evaluating based on chronological age.
