This study introduces a development of calculus contents which makes to understand the main concepts of calculus in a short period of time and to enhance problem solving and computational thinking for complex problems encountered in the real world for college freshmen with diverse backgrounds. As a concrete measure, we developed 'Teaching and Learning' contents and Python-based code for Calculus I and II which was used in actual classroom. In other words, the entire process of teaching and learning, action plan, and evaluation method for calculus class with Python based coding are reported and shared. In anytime and anywhere, our students were able to freely practice and effectively exercise calculus problems. By using the given code, students could gain meaningful understanding of calculus contents and were able to expand their computational thinking skills. In addition, we share a way that it motivated student activities, and evaluated students fairly based on data which they generated, but still instructor's work load is less than before. Therefore, it can be a teaching and learning model for college mathematics which shows a possibility to cover calculus concepts and computational thinking at once in a innovative way for the 21st century.
Objective : The purpose of this study was to analyze the format and effects of lifestyle intervention provided to community dwelling older adults. This systematic review was written following the PRISMA guideline. Methods : The National Digital Science Library(NDSL), RISS, PubMed, and CINAHL were used to search for articles published from January 2008 to December 2017. In total, 20 articles were selected for the analysis and the risk of bias was screened through the Physiotherapy Evidence Database Scale. Lifestyle interventions in the articles were classified according to the disease of the participants. Results : Major contents of the lifestyle interventions were increased physical activity like moderately intensive exercise and education or training to help participants have a healthy diet. Of the 20 articles, 17 included more than 2 types of contents. Examining biochemical factors was the most common measurement among the multifaceted measurements used to assess the effects of lifestyle interventions. The results of the lifestyle interventions described in each article did not indicate congruent effects. 14 of the 20 articles reported the lifestyle interventions had significant effects. Conclusions : The results of this study could help practitioners select the contents of and provide lifestyle interventions to older adults. Further study on the various applications of lifestyle interventions in a community setting is necessary.
This study aims to provide the research for dental technician's stress prevention and management with basic materials by understanding dental technician's psychosocial stress level and examining relevant factors. The subject of this study is 255 dental technologists who work mainly in Seoul Gyeonggi district for a month of April of 2009 and I conducted cross-sectional study through self administered survey. The contents of survey include general feature, occupational feature, health behavior feature. I used Karasek's Job Content Questionnaire, JCQ and Psychosocial well-being index, PWI-SF as means of measurement. To compare the level of dental technician's psychosocial stress, I conducted t-test and ANOVA and I measured the factors that are related with psychosocial stress symptom with step by step multiple regressive analysis. According to the result of Cronbach's a value which is yielded to verify the reliability of means of measurement, the reliability of concept is sufficient. The detailed result of this study is as follows. 1. According to the result of analyzing the stress symptom in accordance with general feature and occupational feature, those dental technologists who are older and not married, graduate from junior college, have lower position, work at university hospital or general hospital show lower stress(p<0.05). There is no difference in the level of psychosocial stress with regard to duty related feature, period of service, daily average working hours, monthly average pay. 2. With regard to health behavior feature, those dental technologists who control weight better and have meal more regularly show lower stress(p<0.05). Those dental technicians who smoke, drink liquid and take a suitable sleep show low stress but the difference does not have significance statistically. 3. With regard to the factors of stress in the workplace, those dental technicians who have lower duty related requirement, have higher duty related control ability, have higher social support, have less instability of employment and have less workload and physical burden show lower stress(p<0.05). 4. According to the result of analyzing the factors that influence dental technologist's stress symptom, social support has the most enormous influence on stress symptom. Unstable employment, regular exercise, regular eating, daily average sleeping hours and technological capacity are also important in this order. According to the result of this study, those dental technicians who have higher social support, less instability of employment, do exercise more regularly, take enough sleep more soundly and have higher technological capacity show lower psychosocial stress symptom. Therefore, to adjust appropriately the dental technician's stress and properly maintain and improve the dental technician's mental health, effective management plan that enables dental technicians to maintain smooth human relationships for dental technicians should be sought. In addition, heath education and health management for dental technicians should be given more thoroughly so that they can establish desirable health behavior in daily life.
The aim of this study was to investigate the cardiometabolic risk factors (CRF) of community dwelling women based on a combination of body mass index (BMI) and waist circumference (WC). This cross-sectional study was based on 1,447 subjects between 30 and 60 years of age. Subjects were categorized into 4 groups by BMI and WC [group 1, BMI<$25kg/m^2$ and WC<85 cm; group 2, BMI<$25kg/m^2$ and WC>85 cm; group 3, BMI>$25kg/m^2$ and WC<85 cm; and group 4 (BMI>$25kg/m^2$ and WC>85 cm. Logistic regression analyses showed that subjects in group 2 had 1.75 times increased risk of clustering of 2 or more CRFs compared with subjects in group 1 (p<0.001). In conclusion, early detection of people with normal weight but high waist circumference may prevent them from getting worse by implementation of lifestyle intervention, consisting of regular exercise and healthy eating. In addition, further studies on appropriate exercise contents for them should be examined.

The purpose of this study was to determine the status of interventional studies to prevent falling in elderly with dementia and to determine the contents and effectiveness of intervention programs to prevent falling. Existing reports published between January 1, 2000 and December 31, 2016 were searched electronically using the RISS, National Library, KISS, PubMed, and CINAHL database with the keywords dementia, Alzheimer's or Alzheimer's disease, falling, and prevention of falling. After checking the original sources of the articles, 13 articles were included in the review. Therapeutic interventions used in the articles included exercise therapy (8, 61.5%), physiotherapy and occupational therapy (2, 15.4%), complementary therapies (2, 15.4%), and music therapy (1, 7.7%). As a result of the qualitative evaluation of the papers using a checklist of the Scottish Intercollegiate Guideline Network, two studies scored 9 out of 10 points, five studies scored 8 out of 10, and six studies scored 7 out of 10. Intervention sessions were conducted for 55 minutes, on average, for a total of 37 sessions. This study found that exercise, music therapy, physical and occupational therapy, and rhythmic motion therapy were effective in preventing falling in the elderly with dementia. In the future, these findings are expected to be used as a basis for the development of a preventive intervention program for nurses in a clinical setting.
The objective of this study is to describe the frequency of workplace health promotion activites. For this objective, questionaire was requested to 648 trainees of Korea Industrial Safety Corporation. Respondents' positions were safety manager, health care manager, or representatives of employee. Major findings are as follows: 1) Of responding workplaces, 66.2% supported the activities related to promote employees' health. The support rate was higher of Manufacturing and Tranport than others. And the lager workplaces had the higher support rate. 2) Most frequent activity is exercise program. But the prevalence of smoking cessation, stress management, nutrition education and women health care was very low. Major contents of support were to pay the cost of these activites and to equip the places or the facilities. 3) 24.9% had the non-smoking policy in the workplace. 98.6% equiped the places and facilities for employees. Mean number of facilities across all workplaces was 2.96 and that of exercise circles was 3.60. In conclusion, it was suggested that the stratege was needed to develop the Korean model for workplace health promotion on the basis of exisiting activites.

Effect of terrapin or snake extract on forced-swimming capacity and related biochemical parameters of SD rats was evaluated. Treatment groups were fed diet supplemented with 5% terrapin extract or 1% snake extract for 4 weeks. After adaptation for 1 week, each group was divided into two subgroups: one group swam for 90 min (90-min subgroups), and the other swam until exhaustion (all-out subgroups). No significant difference was observed in swimming time until exhaustion among the groups. After swimming for 90 min, contents of fatigue factors of serum such as lactate, inorganic phosphate, creatine kinase, and ammonia were not significantly different (p < 0.05) between control and treatment groups, including all-out subgroups, except for lactate concentration. These results indicated that terrapin or snake extract had little effect on forced-swimming capacity of rats.

The operations of fractions are the main contents of number and operations in the elementary mathematics curriculum. They are also difficult for students to understand conceptually. Nevertheless, there has been little study on the addition and subtraction of fractions. Given this, this paper explored the connection between the national mathematics curriculum and its concomitant textbooks, the adequacy of when to teach, and the method of constructing each unit to teach addition and subtraction of fractions. This paper then analyzed elementary mathematics textbooks and workbooks by three parts aligned with the general instructional flow: 'introduction', 'activity', and, 'exercise'. First, it was analyzed with regard to the introduction part whether the word problems of textbooks might reflect on students' daily lives as intended, how different meanings of operations would be expected to be taught, and how the subsequent activities were connected with the original word problems. Second, the main analysis of activity part of the textbooks dealt with how to use concrete or iconic models to promote students' conceptual understanding of operations and how to formalize the calculation methods and principles with regard to addition and subtraction of fractions. Third, the analysis of the part of exercise in the textbooks and workbooks was conducted with regard to problem types and meanings of operations. It is expected that the issues and suggestions stemming from this analysis of current textbooks and workbooks are informative in developing new instructional materials aligned to the recently revised mathematics curriculum.

This study was conducted with 50 elderly people each (5) participating in the cognitive rehabilitation treatment program at the Dementia Care Center in D City to derive the development direction and contents of a multidimensional therapeutic recreation program and a revitalization plan through analysis of the current status and actual conditions of the cognitive rehabilitation program at the Dementia Care Center. aperture) was selected, and 9 people were selected as the subject of expert group opinion collection. The collected data was SPSS ver. Using the 18.0 statistical program, descriptive statistics and the importance and priority of each component were analyzed by hierarchical structure analysis. First, unlike the needs of users, the cognitive rehabilitation support programs currently being provided are not sufficient and require considerable experience. It was found to be low, and the areas for improvement were the expansion of care and protection facilities and the development of various programs to meet the needs of users. Second, the importance and priority of each component of therapeutic recreation were categorized into 6 major categories: exercise therapy , middle category (16 items) behavior-centered approach to exercise therapy, small category (47 items) strength and brain gymnastics, and silver health gymnastics were the highest. This result shows that a multidimensional program plan that considers the priorities of each area must be made when developing a therapeutic recreation program.
