This study sets out to assess the scientific literacy of secondary school students and to describe their differences according to gender, grade, course. This study involved 112 middle school students and 213 high school students. Their scientific literacy was measured by the Scientific Literacy Test designed by Manhart (1997). A 70-item multiple-choice test was used to assess their scientific literacy. The constructs of science factor included 36 items making up physical science, life science, and earth science subtests. The social aspects of science factor consisted of 34 items in nature of scientific inquiry/knowledge, science as a human endeavor, science and technology, and societal perspectives. A two-way analysis of variance (ANOVA) and t-test were conducted using the SPSS program. The scientific literacy score of the middle school students was 45.17. There was no significant difference according to gender but boys tended to perform better than girls on both the constructs of science factor and the social aspects of science factor. The scientific literacy score of the high school students was 51.79. There was no significant difference according to gender. But, boys tended to perform better than girls on the constructs of science factor. Girls tended to perform better than boys on the social aspects of science factor. The students taking a course on natural science got statistically higher scores than the students taking a course on humanities. The high school students got statistically higher scores than the middle school students.

인공지능 기술의 발달과 함께, 4차 산업 혁명에 관한 사회적 논의가 이슈화됨에 따라 교육 학계도 변화의 목소리를 높이고 있다. 지식기반 사회에서 컴퓨터 활용 역량이 강조되면서, 코딩/소프트웨어 교육 등 테크놀로지 기반 교수학습이 교과목과 관계없이 주목받고 있다. 최근에는 오픈소스를 만드는 사람들에 대한 긍정적 인식이 생겨나면서부터, 그들을 메이커라 지칭하고 메이커를 양성하기 위한 운동이 확산되기 시작하였다. 학계에서도 이 운동을 수용하려고 시도하였으나, 관련 연구에서는 기존 테크놀로지 기반 교수학습과 구분되는 특성을 명백하게 보여주지 못했다. 본 연구는 메이커 교육의 시론적 연구로서, 이재호와 장준형(2017)이 제안한 메이킹 역량을 중심으로 이를 키워줄 수 있는 피지컬 컴퓨팅 교구를 조사하였고, 동시에 활용 가능성을 제안하였다. 초기에 제안된 교구의 활용방안은 현장 교사 3인의 전문가 검토를 받았으며, 그들이 제공한 조언을 참고하여 수정하였다. 보완된 활용방안은 메이킹 역량을 구성하는 분석역량, 설계역량, 구현역량으로 구분하여 제시하였다. 이를 통해 메이커 교육의 이론적 발전과 확산에 기여하고자 하였다.

Objective: Patients with COPD have a lower overall quality of life than normal people. If patients with COPD do not regularly perform physical activities, their exercise capacity is reduced. It could lead to muscle loss, and negatively affect their general physical, social, and psycho-social status. The purpose of this study was to examine association with physical activity, sedentary life time and health-related quality of life in patients with COPD. Method: Of the total of 22,948 participants surveyed in Korean National Health and Nutrition Examination Survey (KNHANES 2013-2015), 8,626 participants were used for this study. Of these, under 40 years, over 80 years, missing values and abnormal values were excluded. Study variables included physical activity level, sedentary time and health-related quality of life variables. The physical activity level assessment tool was measured using International Physical Activity Questionnaire (IPAQ). Sedentary time referred to the amount of sitting time without moving the body. EQ-5D (Euro Quality of Life-5 Dimensions) was used as an index of health-related quality of life. Control variables were age, gender, income level, education level, marital status, comorbidity, smoking, BMI, cough, sputum, COPD severity. For this study, descriptive analysis, T-test, ANOVA and multivariate regression analysis were performed. Results: Of the 1,092 patients with COPD, 76.1% (n=831) were male and 23.9% (n=261) were female, while 39.0% (n=2,939) were male and 61.0% (n=4,595) were female in the comparison group without COPD. The COPD group with high level of physical activity showed a high level of EQ-5D scores ($0.9349{\pm}0.11$, p <0.001). Among patients with COPD, after adjusting for control variables, physical activity and sedentary time (physical activity level, Β=0.047, p <.001), (sedentary time, Β=-0.017, p <.05) were associated with health-related quality of life. Conclusion: Patients with COPD have a higher quality of life as their physical activity increases and the quality of life decreases as the time spent sitting increases. This study suggests that public health experts should consider improving COPD patient physical activity.

The purpose of this study was to promote an enhanced understanding of burnout among medical school professors by reviewing the literature on burnout in domestic and international medical professors, and to seek measures to prevent burnout. To this end, the general concept of burnout and the physical, cognitive, psychological, social, and behavioral symptoms that result from burnout were explained. In addition, the causes and results of high burnout among medical school professors were summarized in terms of demographic characteristics and the duties of educators, researchers, and physicians, and measures to prevent burnout in medical school professors were divided into individual and organizational levels. In order to prevent burnout among medical school professors, sensitive interest in themselves and self-reflection are required at the personal level. At the organizational level, it is necessary to regularly monitor burnout among medical school professors, improve systems, encourage participation in the policy-making process, and develop customized education programs. At the social level, it is necessary to recognize that burnout of medical school professors is a social problem, for which further research is needed. Therefore, in order for medical school professors not to burn out, there must be appropriate interactions among the individuals, organizations, and society, and the consistent attention should be paid to this issue.

The policy regarding school sport club participation that was implemented in 2007 to mitigate reductions in fitness has been reported to be satisfactory at improving the physical, mental, and social health of elementary, middle, and high school students by the students as well as by their teachers and parents. The purpose of this systematic review is to investigate the association between participation in school sport club and character-building among adolescents in Korea, and to provide evidence to inform physical education policies in the future. Using "School Sport Club" as the key word, the Korean electronic databases were searched, and this systematic review included a total of 13 articles. School sport club participation among school students is closely correlated to character-building, prevention of school violence, attitude towards life and attitude toward education. The findings of this study support the Ministry of Education's new policy (2015) to extend and expand school sport club participation and highlights the importance of physical activity.

Software education has started as a compulsary subject or part in elementary, middle and high school, but there is a limitation for using the physical computing toolkit and instructional guidelines that teacher can use. The purpose of this study is to propose a computing education program using a physical computing toolkit called the Micro:bit. The novel instructional model is called "MDIAP" which consists of five stages : Motivation, Demonstration, Imitation, Application, Presentation. Instructional process is presented in spiral, consisting of basic micro-bit sensors, and maker's learning using additional sensors and actuators. This study will help students to enhance creative computational thinking through the MDIAP instructional activities.

Objectives: This study identified how personal characteristics, healthy behavior and social capital might influence on physical activity of adults. Methods: This study used data from the health survey of a city of Korea. We surveyed 1,000 adults sampled by stratified sampling methods from 67,889 households. Outcome variable was the stage of physical activity which was broken into 5 categories. Sociodemographic factors, healthy behavior, self-rated health status and social capital were used as control variables. Sociodemographic factors included age, sex, educational status, economic status measured by deprivation score, residential period within survey city. Social capital was measured by Integrated Questionnaire for the Measurement of Social Capital (SC-IQ). This study used chi-square test and ordered logistic regression models to examine the associations between independent variables and physical activity. Variables were added to the regression model in three groups using a hierarchical approach. Results: Physical activity was significantly more likely to become active if they have higher educational status, healthier behavior. Among the six dimensions of SC-IQ, only "groups and networks" that is structural dimensions of social capital and "trust and solidarity" that is cognitive dimensions of social capital were significantly related to physical activity of adults. We found that a person having higher density of membership and having larger size of networks showed the high possibility of active physical activity. A person having high solidarity was significantly associated with physical activity, but general trust was inversely related to physical activity. Output dimensions of social capital did not show significant relationship to physical activity. Conclusion: We found that social capital is useful concept to explain health behaviors like physical activity. However we must consider social, cultural and political context of the study to evaluate the effect of social capital to health status and health determinants and to capture the exact meaning of relationship between them. We suggest further researches to refine the concept of social capital and to explain the relationship of social capital to diverse health determinants.

Oil and natural gas reserves have been recognised abundantly in clayey rich rock formations in deep costal reservoirs. It is necessary to understand the sedimentary history of those reservoir rocks to well explore these natural resources. This work designs a group of laboratory experiments to mimic the physical process of the sedimentary clay-rich rock formation. It presents characterisation results of the physical properties of the artificial clayey rocks synthesized from illite clay, quartz sand and brine water by high-pressure consolidation tests. Special focus is given on the effects of illite clay content and high-stress consolidation on the physical properties. Multi-step loaded consolidation experiments were carried out with stress up to 35 MPa on mixtures constituting of the illite clay, quartz sand and brine water with five initial illite clay contents (w=85%, 70%, 55%, 40% and 25%). Compressibility and void ratio were characterised throughout the physical compaction process of the mixtures constituting of five illite clay contents and their water permeability was measured as well. Results show that the applied stress induces a great reduction of clayey rock void ratio. Illite clay contents has a significant influence on the compressibility, void ratio and the permeability of the physically synthesized clayey rocks. There is a critical illite clay content w=70% that induces the minimum void ratio in the physically synthesised clayey rocks. The SEM study indicates, in the high-pressure synthesised clayey rocks with high illite clay contents, the illite clay minerals are located in layers and serve as the material matrix, and the quartz minerals fill in the inter-mineral pores or are embedded in the illite clay matrix. The arrangements of the minerals in microscale originate the structural anisotropy of the high-pressure synthesised clayey rock. The test findings can give an intuitive physical understanding of the deep-buried clayey rock basins in energy reservoirs.

Chemical compositions of planetary nebulae are of interest for a study of the late stage of stellar evolution and for elemental contributions to the interstellar medium of reprocessed elements since possibly a large fraction of stars in 0.8 - 8 $M_{\bigodot}$ range go through this stage. One of the methods for getting chemical composition is a construction of theoretical photoionization models, which involves geometrical complexities and a variety of physical processes. With modelling effort, one can analyze the high dispersion and find the elemental abundances for a number of planetary nebulae. The model also gives the physical parameter of planetary nebula and its central star physical parameter along with the knowledge of its evolutionary status. Two planetary nebulae, NGC 7026 and Hu 1-2, which could have evolved from about one solar mass progenitor stars, showed radically different chemical abundances: the former has high chemical abundances in most elements, while the latter has extremely low abundances. We discuss their significance in the light of the evolution of our Galaxy.

The purposes of this study are to identify the degree of exercise intent and behavior and to determine factors influencing exercise and behavior in middle school students. The subjects for this study were 658 middle school students in Chonbuk area. The data were obtained by questionaire for the period from Nov. 1 to Dec. 20, 1990. The instrument used for the study were included 6 existing scales and 2 scales developed by the researcher for this study. They are: 1) The exercise intent scale to assess the exercise plan even when they had no longer physical education. 2) The current exercise behavior to measure of exercise frequency for 1 week. 3) The scale to measure the level of self -esteem. 4) The scale to measure the level of knowledge about exercise. 5) The scale to measure the level of the perceived ability to make commitment. 6) The scale to measure the level of the perceived benifit of exercise. 7) The scale to measure the level of the perceived athletic ability. 8) The scale to measure the level of the attitude toward physical education. The data were analyzed using frequency, percentage, one way ANOVA, Pearson Coeffecients Correlation and stepwise multiple regression. The following; results were obtained. 1. Exercise intent level was in the intermediate range(mean on five point scale of 3.66, with 1 = definitely no). 2. The current exercise behavior level was relatively low(mean=1.77, with l=less than once per week and 4 = 4 or more times per week). 3. Self -esteem levels were in the intermediate range(mean on five point scale of 2.96, a mean of 5.0 indicate highest level of self-esteem.) 4. The levels of perceived ability to make commitments were in the intermediate range(mean=3.05, with 5.0 as most able). 5. The levels of perceived exercise as benificial were relatively high(mean=3.72, with 5.0 as most benificial). 6. Knowledge levels about exercise were realatively high(mean=3.97, with 5.0 as most knowledgeable). 7. The levels of perceived athletic ability were in intermediate range(mean=3.01, with 5.0 as highest score). 8. The levels of attitudes toward physical education were in the intermediate range(mean=3.29, with 5.0 as most favorable). 9. Among the general characteristic variables, sex, interest sports activities were related to the difference of exercise intent levels. 10. Of the predictor variables analyzed, self - esteem, perceived benifit of exercise, perceived athletic ability, knowledge about exercise and attitude about physical education correlated significantly and positively with exercise intent. Correlations of predictors with current exercise behavior were similiar to exercise intent, exept knowledge about exercise. 11. The stepwise multiple regression analysis shows findings as follows: 1) The most important factor to explain the difference of exercise intent was current exercise behavior. 2) The most improtant factor to explain the difference of current exercise behavior was perceived athletic ability.
