The purpose of this study was to investigate the status of a school foodservice menu evaluation and the perception of the school's dietitian on menu evaluation. Questionnaires were distributed to 448 school dietitians with an official letter, and a total of 292 responses were used for analysis. More than 90% of the respondents stated that a menu evaluation for the school foodservice was necessary. The major barriers to menu evaluation were "excessive workload" and a "lack of know-how", and the expected benefits were "increased satisfaction of customers" and "increased foodservice efficiency". The menu evaluation for "student preferences", "health improvement", and "ease of quality management" categories were performed in more than 45% of schools. The proportion of subjects who answered that "customer satisfaction" and "increased efficiency of foodservice" were expected benefits of menu evaluation were significantly higher in the menu evaluation group (p<0.05).

An important element to consider in information subjects is problem solving skills. It is problem solving skills that emphasize "practical usage of learning" in which knowledge of information subjects is integrated along with the cross curricular characteristics of the information subjects. What is usually considered paramount in a subject is knowledge, so the question is, should problem solving be considered more important in information subjects? This study discusses the foundation of subjects based on knowledge in information science, and the specifics of the 2014 amendment to the U.K. curriculum. And based on the core subjects of the U.K. curriculum, this study also offers educational implications as to how knowledge and problem solving skills should be discussed.

Ultrastructure of ocellar system was studied in adult Drosophila melanogaster. Ocellus was composed of terminal receptors, interneuron and glia. These three part showed different brightness each other and each component was distinct. In the glial cell, rER was abundant, and terminal receptors and interneuron showed numerous microtubules, special transporting system. The terminal receptors have particular structure referred as capital projection connecting the terminal receptor to glia. In synaptic active zone between terminal receptor and interneuron, ribbon-like structures and synaptic vesicles around the structures were frequently observed. In addition, the cross section of giant interneuron was also observed.

Background: This study was conducted to investigate the actual status of dental hygienists' CPR-related educational experiences and the actual status of dental hygienists' CPR license retention, and to investigate the differences and correlations among CPR-related knowledge, attitudes, and performance abilities. Methods: An online self-reported questionnaire was filled out by 200 dental hygienists nationwide from May 6 to 29, 2019. The data regarding the sociodemographic characteristics, CPR-related knowledge, attitudes, and performance abilities were collected and analyzed using the chi-square test, independent t-test, one-way ANOVA, and the Pearson correlation coefficient using IBM SPSS Statistics version 20.0. Results: Dental hygienists with CPR-related education experience showed high levels of knowledge in the area. Dental hygienists with CPR-related education experiences and dental hygienists with CPR licenses showed high CPR performance abilities. Positive correlations are observed among CPR-related knowledge, attitude, and performance abilities. Conclusion: As CPR-related education has been found to be of value and importance to dental hygienists, systematic educational programs as well as support for regular education will need to be implemented.

The purpose of this study was to investigate the effect of science-based STEAM program on the positive science experience of elementary school students. The participants of this study were 64 fourth graders of S elementary school located in Gyeonggi-do. They were divided into the experimental group of 30 students and the comparative group of 34 students. The program was reorganized into the STEAM program, which emphasized communication with students in the second semester of 4th grade, centered on 'Earth and Moon' unit which were carried out in total 16 times. The experimental group was giving the science-centered STEAM program, and the comparative group was giving the general instruction model based on the instructional book guidelines. The results of the study are as follows. The science-centered STEAM program showed a further influence on the positive science experience of elementary school students. Based on these results, it can be confirmed that the class using the science-centered STEAM program positively influenced the improvement of students' positive science experience.

Science textbook is the most frequently used teaching material in elementary schools of the United States and Korea. Elementary science textbooks of the United States and Korea are analyzed to find out the educational objectives and characteristics of contents shown in textbooks. About 100 pages each in the first grade and fourth grade science textbooks each nations are selected randomly for educational objective analysis. Life science contents of 1st to 6th grade are analyzed from elementary science textbooks of the United States and Korea. The analyzed textbooks in Korea are 'Wise life,' an integrated subject with social studies and science, and 'science.' The analyzed elementary science textbooks of the United States are Harcourt Science, which is one of the frequently used textbooks. The educational objective framework used includes science knowledge, scientific inquiry, scientific attitude, STS, and philosophy and history of science. The results show science textbooks of the United States emphasize scientific knowledge more than scientific inquiry. Korean science textbooks emphasize scientific inquiry more than scientific knowledge. Elementary science textbooks of the United States present some life science topics redundantly and expose more difficult topics than Korean.

The IT(Information Technology) is very important growth power in the knowledge information based society. But there is nothing an educational program or system for putting the computer science education in the primary and secondary school into practice. We can talk this problem because of the national curriculum. This existing state brings to a conclusion not only to the political and administrative support but also to the national curriculum. These internal problems are two. First problem is the content in the computer textbook. And second problem is the connection between the computer science education curriculum of university and that of primary and secondary school. This study analyzed the relation about it. And this study suggested the ideal method for connecting those of them. Finally, the results of this study are two. First result is the necessary to reconstruct the domain knowledge of the computer based on the computer science for getting the identity. And second result is necessary to connect between the domain knowledge of the computer based on the computer science identity of university and that of primary and secondary school.

The purpose of this research is to estimate the chemistry teacher's perceptions of Chemistry I course based on the 7th national curriculum through actual class teaching situations and interviews and teaching guidance of an actual class through a lesson and an interview. For this research, four chemistry teachers who have had an experience teaching the chemistry I course were selected. As the results of the research show, chemistry teachers had the correct understanding of the purpose of the Chemistry I course, but they were teaching the concepts of Chemistry II . They thought the reason for the teaching was the national scholastic aptitude test. But according to analysis, the contents of the previous tests were hardly beyond the limit of Chemistry I course. For this research, the chemistry teachers looked for the purpose of Chemistry I course based on the 7th curriculum only at the superficial views, and the teacher's wrong understanding about the tests disturbed the revelation of the spirit of Chemistry I course of the 7th national curriculum.

한ㆍ중수교는 두나라 국민의 염원에 따라 실현되었다. 한·중수교는 양국의 정치, 경제, 외고, 군사, 과학기술 및 사회의 모든 영역에 획기적 변화를 가져올 것이다. 중국은 정치국면이 안정돼 개혁개방을 기본 국책으로 장기간 정책을 집행해 나갈 것이다. 생산활동이 사회화, 국제화 시대에 접어든 새로운 시대에 그 어느 나라도 개혁, 개방하지 않으면 그 나라는 가난에 빠지고 결국은 남에게 억눌리게 된다.(중략)
