Objectives: The purpose of this study was to provide basic data for air pollutant exposure modelling and understanding the contribution of respective microenvironments by assessing the time-activity patterns of Korean students according to variables such as grade, sex, weekday, and weekend. Methods: In this study, we compared the residential time of 521 (both weekday and weekend) lower elementary students, 1,735 (1,054 on weekdays, 681 on weekends) upper elementary students, 2,210 (1,294 on weekdays, 916 on weekends) middle school students, and 2,366 (1,387 on weekdays, 979 on weekends) high school students in different microenvironments according to grade, sex, weekday, and weekend. We used data from the 2014 Time-Use Survey by the Korean National Statistical Office for upper elementary students through high school students, and surveyed time-activity patterns of 521 lower elementary students aged 7-9 years. Each microenvironment was divided into indoor, outdoor, and transport. Indoor environments were divided into home, school, and other places. In addition, the results of previous studies were compared to this study. Results: Weekday time-activity patterns of Korean students indicated that lower elementary students spent $16.02{\pm}2.53hr$ in the home and $5.37{\pm}2.32hr$ in school. Upper elementary students spent $14.11{\pm}1.79hr$ in the home and $6.27{\pm}1.37hr$ in school. Middle school students spent $12.83{\pm}2.22hr$ in the home and $7.48{\pm}1.88hr$ in school. High school students spent $10.65{\pm}2.86hr$ in the home and $10.23{\pm}2.86hr$ in school on weekdays. High school students spent the least amount of time in the home and the most time in school compared to other grades Conclusions: Students spent most of their time indoors, including in the home, school, and other indoors. On weekdays, as the grade increases, home residential times were decreased and school residential times were increased. Differences in time-activity patterns according to sex were not found for either weekdays or weekends. It is estimated that Korean students could be affected by school indoor air quality. High school students could be most affected by school indoor air quality since they spent the most time at school.

This study had been analysed the establishment, the closing and the actual conditions of the fisheries school according to the four times revision and promulgation of the law of education of korea which were devided by the early term (the first Chosun educational decree), the middle term (the second Chosun educational decree) and the last term (the third and fourth Chosun educational decree), and also been investigated how the fisheries education of the school had been acted to the mobocracy and the assimilation policy and together with it's back ground through this analysis. The aim of this study is to contribute to the study of the history of the fisheries school education, analysis of change of the fisheries school education according to practical application of the Chosun educational decree. The summary of the characteristic of the each term are as under. First, in the early term of the fisheries education under the first Chosun educational decree, Experts were despatched to the each province with donated money from emperor and opened seasonal the fishing training centre, a kind of social fisheries education, and trained directly fishing technic and were going to train fisheries trainees regularly under name of elementary fisheries school. Japanese imperialism attached great importance to the vocational education in order to snack economical products from colonized Korea but actually had a purpose to train low quality technician who follow blindly their colony policy of Japanese imperialism. The fisheries schools in the circle of system in early time of Japanese imperialism, Kunsan public elementary fisheries school was established in April 1915, Yosu public elementary fisheries school was established ill May 1917 and Kyungnam Tongyoung training school was established in March 1917. Secondly, After 3.1 movement, the Japanese imperialism established an appeasement policy so called cultural politics and continued assimilation policy with skilful methods. After revision of the second Chosun educational decree, the Elementary vocational school was changed as the vocational training school. The school of fisheries education in middle of Japanese imperialism trained low quality technicians to snack fisheries resources from colonized Korea. After the middle of Japanese imperialism they paid attention on training fisheries technician through fisheries school rather than training school. With high interest and crowded volunteers, Kunsan public fisheries school was promoted in 1922, Tongyoung public fisheries school was promoted in 1923, Yongampo fisheries training school established in 1922 was promoted as Yongampo public fisheries school in 1926. Thirdly, in the time of the third and fourth Chosun educational decree, the end of Japanese imperialism, they met Pacific war after Japan vs China war. During the war time they considered the vocational school as the source of supply for materials and manpower and consequently had to expanded vocational education and systematically despatched students to war field and practiced military training. In 1938, Namhae public fisheries school was established and Chungjin fisheries school was permitted. But in order to supply manpower to Pacific war, the study period of Yosu public fisheries school was shorten from 5 years to 4 year in 1943 and also that of Tongyoung public fisheries school shorten in 1944.

이 연구에서는 초등, 중, 고등학교의 학생과 교사가 선호하는 SSI 주제를 조사하여 학교급별 학생과 교사가 선호하는 SSI 주제의 유사성을 코사인 유사도 측정을 통해 분석하였다. 연구 대상은 초, 중, 고등학생 566명, 교사의 327명이었다. SSI 관련 선행연구 논문과 프로그램에 포함된 SSI 주제 60개를 환경, 과학기술, 보건·의학, 기타 사회 문제 영역로 구분하고 목록화하여, 연구 대상인 학생 또는 교사가 선호하는 주제 5개를 선택하도록 하였다. 자료수집은 서베이몽키를 이용한 온라인으로 진행하였고, 수집된 자료는 학생 및 교사별로 6개 집단으로 구분하고, 집단별로 주제의 선택 빈도를 조사하였다. 그리고 선택된 주제의 빈도를 기준으로 벡터 값을 계산하고, 학교급별 학생 간, 교사 간, 교사와 학생 간의 코사인 유사도를 측정하여 주제 선호 유사도를 분석하였다. 연구결과는 다음과 같다. 첫째, 학생의 학교급별 집단간 SSI 선호 주제 유사도는 중학생과 고등학생 사이의 코사인 유사도(0.982)가 초등학생과 중학생간(0.651) 또는 초등학생과 고등학생간(0.662)의 코사인유사도보다 높았다. 둘째, 교사의 학교급별 집단간 SSI 선호 주제 유사도는 초등, 중, 고등학교간의 모든 비교 집단에서 비교적 비슷한 코사인 유사도의 양상을 보였다. 셋째, 학생과 교사간 학교급별 SSI 선호 주제 유사도는 초등학교 학생과 교사 집단간 코사인 유사도(0.974)가 다른 학교급의 비교 집단, 중학교급(0.621) 또는 고등학교급(0.645)보다 높았다. 즉 초등학교의 학생과 교사는 서로 선호하는 SSI 주제가 73.33%의 수준에서 유사하고, 반면, 중학교 또는 고등학교의 학생과 교사는 서로 선호하는 주제가 33% 수준으로 유사한 경향을 보였다. SSI 교육에서 학생에게 관심 있는 주제로 접근하는 것은 학습 동기 유발과 지속, 그리고 즐거운 학습 경험과 학습에 대한 긍정적인 태도 형성과 긴밀하게 연관된다. 따라서, SSI 수업을 설계할 때, 학생 관심의 관점에서 주제를 검토해야 할 것이다. 특히 교사가 학생의 선호도와 다소 차이가 있는 SSI 주제를 선별한 경우, 그 차이를 극복할 수 있는 치밀한 교수 설계가 필요할 것이다.

With more emphasis on importance of software, many countries try to provide software education. Of course Korea includes informatics courses in 2015 revised curriculum, so that software education will be administered briskly in soon. However there are practical challenges including a lack of teaching hour in classes and the monotony of educational contents which occurs with that. To solve these problems, this research develop software education curriculum model that could be practically used for both middle and high school. First this study compare the curriculum of Korea to that of United States and United Kingdom. After analyzing the result, the curriculum model for middle and high school is developed. The curriculum model can be classified into three types, middle, high and advanced-high levels and include key concepts like collaboration and convergence, computational thinking, computing practice and programming, computers and communications devices, community, global, and ethical impacts. To assess the feasibility of our software education curriculum model, examination was made by expert group and a hearing was held by related researchers. Then the model was modified in a way that adjustable to Korea education system. This study provides some important guidances on designing a curriculum for software education at middle and high school. However, there still are difficulty adjusting to the elementary school and university course. To be able to further research, same kind of studies on elementary school and university course need to be done. Also, continuous modifications are required to reflect reality including technological advance, curriculum, and changes of education system.

This study conducted a survey and investigated students' opinions and design preferences to physical education (PE) uniforms for elementary, middle and high school students using PE uniforms for the following purposes: to increase satisfaction with PE uniforms; present basic data for the development of PE uniforms helping to improve the quality of school life; and propose the development direction of PE uniforms. PE uniforms shall be developed with the components of uniforms, symbolism, functionality and aesthetics. The symbolism of PE uniforms expresses the affiliations of people wearing them and makes them have a sense of affiliation. The functionality presents convenience in students' physical activities and intramural/extracurricular activities. The aesthetics reflects the aesthetically sophisticated sport wear trend in PE uniforms. The development direction of PE uniforms was organized based on the result of analyzing and investigating students' opinions and design preferences to PE uniforms. There were differences in students' opinions and preferences to PE uniforms according to the type of student groups (elementary, middle and high school). In addition, there were clear gender-differences in the same student group. An effort might be required to reflect students' preferences because PE uniforms which students had currently worn at school had been manufactured without the reflection of students' opinions.

A total of 262 dietitians (in 97 college foodservices nationwide, 86 elementary school foodservices, and 79 middle & high school foodservices in the Changwon area) were given a survey questionnaire composed of 18 GMP and 29 SSOP items from May to July, 2011. As a whole, total usage level of GMP facilities (3.65/5 points) and total management level of SSOP (3.86) in college foodservices showed no significant differences compared to those in elementary school foodservices (GMP 3.74, SSOP 4.02) and middle & high school foodservices (GMP 3.75, SSOP 3.95). However, the results of this study suggest that seven items of the GMP facilities and five items of the SSOP should be improved for the development of the HACCP facility model in college foodservices. Those items that showed considerably lower points in GMP were as follows: 'Drain pipes from sinks of the cooking area are connected directly to the drain (3.74)' (P<0.001), 'The grease trap is installed outside the cooking area equipped with an oil separator (3.24)' (P<0.01), 'Entrance and the cooking area are adequately equipped with hand-washing and shoe disinfecting facilities (3.61)' (P<0.001), 'Cooking area, food storage, and dining area are adequately equipped with insect and rodent repellents (3.72)' (P<0.001), 'Cooking areas are equipped with air-conditioning/heating system and ventilation facility for maintenance of temperature and humidity (3.35)' (P<0.05), and 'Toilets for cooking staff only are provided; the its doorways are not directly accessible from the cooking area (3.25)' (P<0.01).
