This study was researched to provide the accurate nutrition information and the menu. We questionnaired an recognition and necessity of the nutrition labeling to 684 customers in fast-food restaurants. After data cleaning, we used spss package 14.0 and analyzed about the nutrition contents and place that display the nutrition labeling. First, we finded out lower recognition of nutrition labeling in restaurants than processed food. Second, many people hoped that calory and fat in various nutritions were displayed each 100 g or 100 mL. Third, the place displaying the nutrition information was the menu board and the counter to identify easily. Fourth, we analyzed the recognition and necessity of the nutrition labeling in fast-food restaurants by t-test and ANOVA. So, we knew that the recognition and necessity of the nutrition labeling was higher woman than man. And the more they earn much money and learned, the more the nutrition labeling are needed. But house-wife recognized the nutrition labeling lower than others.

The purpose of this study is to understand how the shift of the Pythagorean theorem influenced the representation of irrational numbers in the 3rd grade textbook of 2015 revised mathematics curriculum by textbook analysis. Specifically, the changes in the representation of irrational numbers were examined in two aspects based on the nature of irrational numbers and the teaching and learning methods of the 2015 revised mathematics curriculum. First, we analyzed the learning opportunities related to the existence of irrational numbers that were potentially provided by treating irrational numbers as geometric representations in textbooks, and confirmed that Pythagorean theorem was used. Next, we analyzed opportunities to recognize the necessity of irrational numbers provided by numerical representations of irrational numbers. This study has significance in that it confirmed the possibility and limitation of learning opportunities related to the existence and necessity of irrational numbers that were potentially provided by changes in irrational number representations in the 2015 revised textbooks.

In recent years, use of machine automation is rising in the industry. Ships also obtain machine condition information from sensor as digital information. However, on ships, crew members regularly surveil the engine room to check the condition of equipment and their information through analog gauges. This is a time-consuming and tedious process and poses safety risks to the crew while on surveillance. To address this, engine room surveillance using an autonomous mobile robot is being actively explored as a solution because it can reduce time, costs, and the safety risks for crew. Analog gauge reading using an autonomous mobile robot requires digitization for the robot to recognize the gauge value. In this study, image processing techniques were applied to achieve this. Analog gauge images were subjected to image preprocessing to remove noise and highlight their features. The center point, indicator point, minimum value and maximum value of the analog gauge were detected through image processing. Through the straight line connecting these points, the angle from the minimum value to the maximum value and the angle from the minimum value to indicator point were obtained. The obtained angle is digitized as the value currently indicated by the analog gauge through a formula. It was confirmed from the experiments that the digitization of the analog gauge using image processing was successful, indicating the equivalent current value shown by the gauge. When applied to surveillance robots, this algorithm can minimize safety risks and time and opportunity costs of crew members for engine room surveillance.

This study investigated for perception about particulate matter in daily lives of mothers who have children aged from three to five years old and the difference of perception after participating in forest experience programs. The data were compiled from 122 mothers of preschoolers composed by 61 mothers who participated in the forest experience and those who did not. 82.8 percent of 122 mothers were concerned with particulate matters, and 84.4 percent frequently checked information on particulate matters. However, they lacked knowledge, countermeasures, and active practice to reduce it. Awareness of forest and fine particulate matter was high among mothers who had participated in the forest experience, with a high positive perception of forest role and forest environment. Therefore, expanding the opportunity for mothers to actively experience forest will contribute not only the forest experience in infants being activated but also to improve harmful environment such as fine particulate matter.

This study analyzed faculties' perceptions on the importance and performance of effective teaching behaviors. The effective teaching behaviors scale consisted of 40 items belonging to 8 factors. A survey was conducted with 86 faculties from 2 universities. It was found that the differences between the importance and performance levels of all items except for 'applying emphasis on important contents' were statistically significant. The scores of importance were higher than those of performance. The results of the IPA showed that 'keep up the good work' area included 19 items that those were high the scores of importance and performance. The 'concentrate here' area included 5 items that need to be improved for effective teaching. The first priority items needing to be improved were 1) Establishing instructional methods and strategies suitable for the objectives, 2) establishing clear objectives, appropriate examples and systematic classes, 3) providing questions, opportunities and appropriate feedback. We suggested that a faculty development program needs to be developed for effective teaching.

As the influence of SW spreads, many countries concentrate on SW education policies for women. Although the SW education is strengthened, study on the curriculum suitable for women is still insufficient. The study conducted 422 middle school students to investigate differences in perception of SW by gender. It consisted of 207 male students and 215 female students, and survey analyzed in three categories : SW environment, SW education awareness and SW career interest. The analysis showed that SW education for female students is necessary to increase the confidence and interest in them, and that SW education opportunities for female students should be expanded so that interest and expectation of information education should be increased. In addition, it is necessary to introduce and promote SW related career path which can increase interest in SW related job and SW related major. This study is meaningful in that at this point when the revised curriculum begins to be applied, there are differences in perception of informatics and SW by gender, and that it is necessary to study the SW curriculum suitable for gender for effective achievement.
