This study aims to explore the influencing factors and the process of enhancing science self-efficacy (SSE) and to lay the foundation in understanding science self-efficacy of students. The ten categories related to the science self-efficacy were derived through the coding of the interview data based on the grounded theory and paradigm analysis to develop a process model of science self-efficacy improvement. Through the process analysis, four cyclical phases were found in the process of enhancing SSE: 'Entering into learning science' phase, 'enhancing SSE' phase, 'adjustment' phase, and 'result' phase. More specifically, the phase of 'entering into learning science' is where students choose science track and stimulated to construct SSE. The phase of 'enhancing SSE' is where students taking a science track actively learn science and perform science activities. In the phase of 'adjustment', students come to have successful performance about learning science and performing science activities by using diverse strategies. Finally, 'result' phase indicates different appearances of students depending on SSE levels. The phases were non-linear and periodically repeat depending on situation. The core category in the selective coding was indicated to be 'enhancing science self-efficacy.' Students' SSE form by learning science and performing science activities. These finding may help better understand the behavior of students who are taking a science track by facilitating effective science learning through the increase of their SSE levels.

This study is for increasing evacuation safety by analyzing RSET(the required safe escape time) through the arrangement of personnel by floor and by room while evacuating in a Girls' High School Dormitory. For this study, PAPS(Physical Activity Promotion System) results that have not been studied so far were analyzed and reflected in evacuation simulations on the premise that individual student's physical strength can affect evacuation. Based on the PAPS results, four scenarios were applied. In addition, evacuation simulation using the pathfinder program was conducted in two situations: the evacuation route was assigned or not. Scenario 4 was the fastest at 168.5 seconds of RSET in assigning evacuation routes among scenarios. As a result of this study, the arrangement of students focusing on improving their academic ability and student life guidance excluding student physical strength has problem. In order to solve this problem, it is effective to place C group students(low grade on PAPS) on low floors and A group students(high grade on PAPS) on high floors and to assign evacuation routes in each room. In the future, the following ways need to be more studied. A study on how to increase evacuation safety through practical evacuation training, the way of assessing evacuation safety reflecting the lifestyle and physical strength of girls, the evacuation route assignment according to the fire occurrence point, and the method to secure evacuation routes in the event of a fire near stairs or entrances should be conducted.

Purchasing behavior for upcycled fashion products was examined along with analysis on environment consciousness, clothing recycling behavior, interest in fashion and awareness of upcycling. Students from middle schools, general high schools and design high schools participated in this research from August to September in 2013. 732 questionnaires were analyzed by SPSS WIN. Firstly the levels of environmental consciousness, clothing recycling behavior and interest in fashion of students were high, low and mediate respectively. Female students showed higher environmental consciousness compared to male ones and clothing recycling behavior were found to be higher in students of design high schools than those of general ones. The level of interest in fashion was found to be higher in students of general high school than those of middle school, and this was higher in design high school students than those of general ones. Secondly, more than half of students were unaware of upcycling. Female students and students of design high schools were highly aware of upcycling. Students who were aware of upcycling showed high level of environmental consciousness, clothing recycling behaviour and interest in fashion. Thirdly, students had low experiences in purchasing upcycled fashion products and the reason was lack of awareness of upcycling. The reason that students purchased upcycled fashion products was the uniqueness and design. Students who purchased upcycled fashion products showed high environmental consciousness, clothing recycling behaviour, and interest in fashion.

School uniform has improved greatly in terms of fit, size, function, and design due to steep competition in the market and the strong interest of researcher, while little effort has been made for physical training uniform, so the objective of this study is to provide basic research data of the training uniform for the improvement of its design and fitness. For this purpose, 327 high school girls provided information on size and design of their uniform, level of satisfaction, the recognized ease in uniform. Most students wore the physical training uniform in another classes and the long sleeved shirt were the most popular one. They often used the uniform for the protection from cold and for comfortable activeness. For a long sleeved shirt, most students preferred raglan sleeve, zip-up collar, straight waist line, and ribbed sleeve cuffs and hem. For long pants, students preferred elastic waist band and ribbed pants cuffs. Currently, the short-sleeved shirt mostly had a shirts collar, ribbed hem, straight waist line with raglan sleeve, but students wanted a round neck and set-in sleeve. For overall level of satisfaction, students showed high satisfaction in terms of function and psychological effect, while aesthetic quality of the uniform was needed to be much improved. Most students evaluated that the circumference of uniforms properly fit or had a little ease, and students considered waist size the most suitable. The long pants length evaluated properly fit or a little long. Students accepted that the ease of summer uniform was more suitable than winter uniform's both at circumference and at length. Depending on students' height distribution, the length of long pants and short pants varied significantly.

This study was conducted to obtain accurate data on intake, excretion, apparent digestibility and balance of zinc which Korean take in habitually. This study applied to the seven high school girls from 15 to 16 years old. Their food intake, feces and urine were collected and intake and excretion of zinc in them were measured by atomic absorption spectrophotometry. The measurement continued for four weeks while they maintained their normal living pattern and body weight. Each girl's daily intake and excretion of zinc were measured and apparent digestibility and balance were also studied. Each girl's daily mean intake, fecal excretion and apparent digestibility of zinc were $9.26{\pm}2.30mg,\;3.31{\pm}2.15mg,\;and\;62.92{\pm}3.22%$, respectively. The urinary excretion of zinc was $3.23{\pm}1.03mg$ and showed the positive balance of $2.61{\pm}2.91mg$.

This study examined the food group and dietary nutrient intakes by sugar-sweetened beverage(SSB) intake level in high school students aged 15~18 years(n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey. Subjects were classified into three groups by SSB(included carbonated drinks, sports drinks, and caffeinated drinks that contained added sugars) intake level obtained from 24-hour recall method: SSB 1(SSB intake 0 g/d), SSB 2(0 g/d < SSB intake < 50th percentile) and SSB 3(SSB intake ≥ 50th percentile). Result of daily intakes of SSB were 160.6±10.5 g/d for boys and 98.6±7.1 g/d for girls and it increased for boys(p<0.0001) and girls(p=0.0280) by year. The highest intakes were carbonated drinks followed by fruit juices for boys and girls. Intakes of carbonated drinks increased as 2.7 times for boys(p<0.0001) and 1.6 times for girls between 2007 and 2015 year. Daily intakes of vegetables were the lowest in SSB 3 of three groups for boys and girls(p<0.0001), and those of fruits were lower in SSB 2 and SSB 3 than SSB 1 for boys(p=0.0013). Daily intakes of milk & milk products decreased toward SSB 3 group for boys(p<0.0001) while those were the lowest in SSB 3 of three groups for girls. Daily intakes of dietary fiber(21.3~25.3%) and calcium(49.6~59.8%) were very low compared to the dietary reference intakes. Percentage of daily intakes compared to the dietary reference intakes increased for energy for boys and girls(p<0.0001) while decreased for vitamin C toward SSB 3 group for boys(p<0.0001) and girls(p=0.0382). Those of calcium were the lowest in SSB 3 of three groups for boys(p<0.0001) and girls(p=0.0008). Ratio of excess intakes of energy/fat increased toward SSB 3 group for boys and girls(p=0.0002). Ratio of calcium deficiency was not different among groups but that was very high(85.9~92.5%). Therefore, it should be emphasized to reduce SSB intakes in order to improve diversity in food group and dietary nutrient intakes among high school students through dietary education and government support.

This study examined the influences of computer-assisted instruction(CAl) upon high school students' conceptual understanding, algorithmic problem solving ability, learning motivation, and attitudes toward chemistry instruction. CAl programs were designed to supply animated molecular motions for emphasizing the particulate dynamic nature of matter and immediate feedbacks according to students' response types at each stage of four stage problem-solving strategy(understanding, planning, solving, and reviewing). The CAl and control groups (2 classes) were selected from a girls high school in Seoul, and taught about gas law for four class hours. Data analysis indicated that the students at the CAl group scored significantly higher than those at the control group in the tests on conceptual understanding and algorithmic problem solving ability. In addition, the students at the CAl group performed significantly better in the tests on the learning motivation and attitudes toward chemistry instruction.
