The purpose of this study is to identify the perceptions of SW education among elementary, middle and high school students, parents, and teachers, and to identify the variables that influence the perception of SW education. For this study, a total of 50 elementary schools, 14 middle schools, and 8 high schools were selected from the stratified sampling method, and an online survey was conducted for students, parents, and teachers. According to the results, the questionnaires of 2,231 students, 615 parents, and 173 teachers were analyzed. According to the results of the study, students, parents, and teachers who had experienced SW leading schools had a high awareness of SW education, and school-level students showed higher recognition in the order of elementary, middle, and high school. As a result of analyzing the difference of perception according to the characteristics of the study subjects, the students were more aware of the fact that male students, students who participated in SW-related club activities, students who participated in SW-related competitions, higher class times of the desired. In the case of parents, the parents of male students, parents who taught SW-related educational activities outside the school, and the parents with high hopes had high awareness. In the case of teachers, the higher the educational experience of SW, the higher the students' perception of the desired time of 2 hours. As a result of analyzing the influence of the characteristics of the subjects on the perception through the multiple regression analysis, the students 'and parents' awareness and the degree of hemming on the SW-related education were found to have a positive effect. In addition, teacher awareness and SW education career were found to have a positive effect.

Objectives: The purpose of the study was to investigate the carbonated beverage consumption and related factors of dental hygiene students in Gwangju Jeonnam. Methods: A self-reported questionnaire was completed by 343 dental hygiene students in the Gwangju Jeonnam area from May 17, 2017 to June 1 based on convenience sampling. The questionnaire consisted of general characteristics of the subjects, the frequency of carbonated beverage intake, its degree of impact on oral health, oral care behavior following the intake of carbonated beverages, and the method of intake. Results:There were 293 people (85.4%) who drink carbonated beverages. The intake frequency was an average of 3.9 times a week, and the most frequently consumed beverage was cola with an average of 1.8 times a week. The intake frequency of carbonated beverage was correlated with a higher share of the cost of the beverage in the subject's monthly allowance, a lower intention of ceasing intake of carbonated beverage henceforth, and a lower grade. Conclusions: It is necessary to raise awareness on carbonated beverages through nutrition education concerning beverages including the harmful effects of carbonated beverages and reinforcement of oral health education in regular education courses. In addition, it is considered necessary to refrain from the consumption carbonated beverages by oneself as a preliminary dental hygienist.

Use of the viamin-mineral supplements markedly increased with the awareness of diet and health. Data were collected from the self-administered questionnaire of 450 free living elderly, 60 to 94 years old, in Korea, to assess the relationships between socioeconomic variables, beliefs about nutrition, and the factors affecting gupplements usage. In addition, vitamin-mineral intakes through the supplements were calculated, and compared with RDA. 44.9% of the subjects took the vitamin-mineral supplements, and significantly higher percentage of women(49.3%) than men(38.1%) took supplements(p<0.05). The higher the education level, monthly pocket money, the percentage of supplements consumption was higher. People living in large cities took more supplements than those in small cities. One of the mainly cited reasons for taking supplements was to maintain health. The most favored nutrient supplements used by the subjects were in the order of vitamin B complex, vitamin E and Calcium, and vitamin-mineral intake through the supplements were much greater than RDA and ranges of their intakes were very wide. Vitamin B1 and vitamin E were observed to consume excessive amount(63 times of RDA and 40 times of RDA, respectively). The reasons for supplementation were often inappropriate and unreliable sources of information were used. Thus nutritional understanding and education of the elderly peopled are needed in regard to the use of vitamin-mineral supplements, and the relationship between adequate diet and good health.

Purpose: Implicit motor learning is the capacity to acquire skill through physical practice without conscious awareness of what elements of performance improved. This study investigated whether subacute stroke patients can implicitly learn a perceptual-motor task. Methods: We recruited 12 patients with subacute stroke and 12 age-matched controls. All participants performed a perceptual-motor task that involved pressing a button corresponding with colored circles (blue, green, yellow, red) on a computer screen. The task consists of 7 blocks composed of 10 repetitions for a repeating 12-element sequence (total 120 responses). Results: Both groups demonstrated significant improvement in acquisition performance. Reaction times deceased in both groups at similar rate within the sequential block trials (2-5 blocks), and reaction times increased at a similar rate when the task paradigm was transferred from the sequential block trial to the random block trial (5-6-7 blocks). Conclusion: The results of this study suggest that patients with sub-actue stroke can implicitly learn a perceptual motor skill. Although explicit instructions should be used to focus the learner's attention rather than provide information about the task, the application of implicit motor learning strategies in the rehabilitation setting may be beneficial.

Objective: The purpose of this study was to determine the force of lower extremities, the change in walking ability on the ground by applying a walking training program based on perceptual learning to improve gait capacity of chronic stroke patients. Method: This study included Twenty-four patients with chronic stroke. Using a perceptual-based gait training, the experimental group trained twice a day for 30 minutes each time, 5 times a week, for a total of 8 weeks. The control group underwent ground gait training that excluded the element of a perceptual training for 30 minutes, 5 times a week for 8 weeks. Results: In the two groups, the maximum forefoot pressure after intervention was significantly different in both the LEPGT and GGT (p<0.05). The maximum midfoot pressure was significantly different in LEPGT (p<0.05). There was a significant difference in the maximum heel pressure after intervention between the two groups (p<0.05). As a result of comparing the change in step length and stride length after intervention in the two groups, there was a significant difference between the two groups (p<0.05). Conclusion: Both gait training programs was found that gait training based on perceptual learning and ground gait training were the training for improving the functional gait of stroke patient. Perceptual learning gait training utilizing intensive perceptual awareness was the training for improving gait capacity within the period than ground gait training.

In many applications of wireless sensor actor networks (WSANs) that often run in harsh environments, the reduction of completion times of tasks is highly desired. We present a new time-aware, energy-aware, and starvation-free algorithm called Scate for assigning tasks to actors while satisfying the scalability and distribution requirements of WSANs with semi-automated architecture. The proposed algorithm allows concurrent executions of any mix of small and large tasks and yet prevents probable starvation of tasks. To achieve this, it estimates the completion times of tasks on each available actor and then takes the remaining energies and the current workloads of these actors into account during task assignment to actors. The results of our experiments with a prototyped implementation of Scate show longer network lifetime, shorter makespan of resulting schedules, and more balanced loads on actors compared to when one of the three well-known task-scheduling algorithms, namely, the max-min, min-min, and opportunistic load balancing algorithms, is used.

This study examined the relationship between family meal time and emotional well-being for 5,186 fathers who were employed and had at least one child aged under 18 for the years 2009 and 2014 by analyzing their time diaries. In doing so, changes in time spent by fathers on family meals between 2009 and 2014 were also examined along with the factors associated with the amount of meal time for each year in order to understand ways to increase paternal participation in family meals. Analytic results showed that a father's family meal time had a positive association with his time use and life satisfaction; however, fathers who spent more than 40 minutes a day having meals with the family reported the highest score in time use and life satisfaction. The amount of time fathers spent on family meals increased from 38 minutes in 2009 to 43 minutes in 2014, whose change turned out to be mainly attributable to something more than the compositional change in the population between the two years, such as growing public awareness or cultural acceptance of the value of family meal. Fathers in dual-earner households tend to have longer family meal times; however, different factors were associated with their family meal times in 2009 and 2014. Policy implications are discussed in light of the government-initiated dining table education campaign to increase family meal time for the sake of children's character education at home.
