  • This study aims to provide basic data about the diversification and the development of sauces by making four kinds of Teriyaki sauce, and the findings are as follows. The satisfaction with Teriyaki sauce by age and cooking career and groups showed a significant difference in several items. According to the result of the preference analysis on professors and teachers, the preference for health/nutrition showed a significant difference; also, the result of the preference analysis on Teriyaki sauce ingredients among the culinary students showed a significant difference in awareness and health/nutrition. In addition, the result of the preference analysis on Teriyaki sauce ingredients among college students showed a significant difference in the order of taste, awareness, price, and health/nutrition. Lastly, the result of the preference analysis on Teriyaki sauce ingredients among all groups showed a significant difference in the order of awareness, price and health/nutrition. As the mindset that main ingredient of Teriyaki sauce is eel bone prevails and the sauce made by crab shells is highly preferred, sauces added with sea food products are considered to be possibly developed. The follow-up study will have to deal with a manufacturing method of sauce with high nutrition and economy efficiency resulting from cheap manufacturing unit price by making Teriyaki sauce with inedible but nutritions sea food products.

  • The purposes of this study was to investigate the effect of inductive Instructional method and deductive one concerning the learners' population genetic concepts and achievement according to learners' cognitive characteristics. For the study, 180 students were sampled from a boys' high school: 90 students for inductive teaching method and 90 students for deductive teaching method. Group Assessment of Logical Thinking(GALT) and Group Embedded Figure Test (GEFT) were used as the measure of cognitive characteristics. The results of this study were as follows. 1) The inductive instructional method was more effective in the understanding of population genetic concepts and their achievement. 2) Inductive instructional method was more effective than deductive one for the learners in formal operational level and in field independent cognitive style. 3) For the learners in a transitional level and field dependent cognitive style, deductive instructional way was more effective than inductive way on the average, but it was not statistically significant. It was turned out that learners' cognitive level was one of important factors when teachers instruct the concept of population genetics.

  • Many researches related to STEAM education have been actively conducted for developing elementary and secondary school students' comprehensive and logical thinking ability in relation to creativity education in Korea. Each sub factor of STEAM education requires creative thinking with the ability to be merged together to solve problems as integrated or combined forms in the fields of Science, Technology, Engineering, Arts, and Mathematics. Also, these STEAM activities and experiences should be carried out at various places outside the classroom in school. Although various educational programs to enhance mathematical creativity have been emphasized for elementary and secondary school students, recent tendency to focus on classroom learning in the school makes it difficult to develop creative thinking ability of students. This research is mainly based on the result of the project "Development and Administration of STEAM Outreach Program in 2016" supported by KOFAC(Korea Foundation for the Achievement of Science & Creativity). The purpose of this research is to develop a STEAM outreach program including students' activity books, teachers' manuals and administration manual that can maximize STEAM-related interest of students, and to provide a chance for elementary and secondary school students to experience creative thinking based on sub factors of STEAM. The STEAM competency total score and the perception of convergence education were significantly increased for all students participating this program, but some sub factors showed different result by school levels. The STEAM outreach program developed by this study is designed to emphasize STEAM education especially 'based on' mathematics in order to provide students with the opportunity to experience more interest in the field of mathematics and will be able to provide an interesting creative STEAM outreach program that utilizes a variety of activities which, we expect, would help students to consider their career in the future.

  • An increasing number of students are giving up on learning mathematics at all grade levels, including elementary school. The study in this paper considers seven non-cognitive student characteristics to identify which are strongly correlated with giving up on mathematics at the elementary school level. Data were collected with a survey on the non-cognitive domain of mathematics learning that was developed by the Korea Foundation for the Advancement of Science and Creativity in 2015. The data were collected from 3,636 elementary school students in Korea, and we analyzed the data using the statistical computing program R. Of the seven components, efficacy and interest have a strong correlation with students' tendency to profess that they have given up trying to learn mathematics. The findings of the study shed light on which non-cognitive domain areas mathematics teachers need to pay more attention to in order to make their teaching effective. This study further investigated the correlation between responses to each of the 24 survey items and students' claim that they have given up on mathematics. Using the 8 items with the highest correlations, we have developed a shorter, 8-item version of the survey, which will be useful for similar future studies.

  • The purpose of this study is to assert the fact that School Library Media Center(SLMC) is the most important body which influences the whole process of loaming in school and at the same time it functions as a very essential infrastructure of acquiring loaming in the society. The writer analysed the studies on learning outcomes across a range of educational conditions and settings. She found that loaming outcomes are influenced positively by the educational conditions and settings that accomodate the student diversity and individualization, and loaming materials for their individual needs. It means that the outcomes of effective teaming are influenced by using teaming materials of individual student guided by teachers and teacher librarians. In case, school education furnishes desirable programs of SLMC and use it properly, students canhave enough experiences what and how they learn by using library materials during their school days. As school days are in their early days of their lifetime, they are easy to carry their way of loaming with them even after they finish school. The members of society who are accustomed to use library materials during their school days will have loaming needs for their better life. The writer wants to call it the loaming needs of society that school produces. A teaming society is composed of two factors One is the loaming needs of the people and the other is the environment to meet them. SLMC produces loaming needs, and it meets to the needs of student learning. Consequently it can be said SLMC is the infrastructure for loaming society. The author pointed out that the Educational Reformation Draft of current Government does not mention about learning materials prerequisite to enhance student loaming outcomes, especially in relation to their creativity. She concluded educators of every level of school including government officials in charge of education have to think and do something about reformation of School Library Media Center for the fulfillment of the goal of Korean Educational Reformation Draft announced by the Educational Reformation Committee Draft announced by the Educational Reformation Committee May 31, 1995.

  • The international standard for the school library suggests that school librarians qualified for librarian and teacher should run the school library. And library assistants should support the teacher librarian to carry out a role as a teacher. Despite the difference of requirements, librarians without teachers' license are under the human resources for school library administration. Furthermore, the job description between the school librarian and librarian is not well-defined in Korea. The different requirements in the library standards and the school library related laws have led to weaken professionalism and social status of librarianship. The condition that teacher librarians are not in the school library have brought the pressure to overcome imperfect functions of the school library and unfairness of educational services. In order to solve these problems, it is necessary to strengthen teacher librarians' qualification system to improve their identity as educational subject specialist librarians. We ought to also build proper foundations of social recognition about librarianship through classifying the types of human resources in the school library into the teacher librarian, library paraprofessional and volunteers. Especially we should hold the job analysis based on administrator, teacher, service, leader, collaboration, and partner.

  • The purpose of this study was to investigate the priority of menu management by importance-performance analysis (IPA) of school foodservice menu attributes. Questionnaires were distributed to 448 school dietitians with an official letter, and a total of 292 responses were used for analysis. From the 21 menu attributes, the factors of 'nutrition', 'educational effect', 'capability consideration', 'ease of quality management', 'efficiency', and 'preference of students' were induced from exploratory factor analysis. The levels of importance (p<0.01) and performance (p<0.05) of the 'nutrition' factor were significantly higher with nutrition teachers than school dietitians, while the importance of the 'preference of students' factor showed significantly higher score with school dietitians (p<0.05). As a result of gap analysis for IPA, only the 'efficiency' factor was located in the area where performance was higher than importance, whereas no menu attribute factors were included in the 'concentrate here' area by the usual IPA. Further analysis showed that there should be more effort to improve the performance of an 'educational effect' factor for a school foodservice menu.

  • This study is based on parents that have preschool children of age 4~5, and analyzes the perception and parent education demand through parent experience of fire. As a result of the study about perception through parent experience about safety life, safety accidents, safety education of fire, the effect of parents' safety consciousness to fire safety life turned out to be moderate for fathers and large for mothers. The safety education method was mostly done in speaking than experience for fathers, while mothers did education through experience in daily life. Also the difficulties in safety education was lack of educating time for fathers while it was lack of knowledge and methods for mothers. Perception through parent experience of fire safety accidents showed that fathers did not have experience of fire safety accidents while mothers did. The locations perceived by parents where fires mostly occurred showed to be within home for both parents, and both administered first aid in managing fires. Perception through parent experience of fire safety education showed the importance of fire safety education to be important in both parents, and both parents had no experience in fire safety education. Also the fire safety education knowledge acquisition method was TV or the Internet for fathers, while it was participating in seminars or lectures for mothers. Fathers were moderately satisfied of the fire safety education instruction of childhood education centers, while mothers were slightly dissatisfied. For the demand of parent education about fire safety education, fathers were moderate while mothers thought it necessary of parent education necessity. The reason why parent education was needed was to be able to know immediate and prompt measures and first aid treatment in emergency situations for fathers, while it was to figure out the cause of fire safety accidents and prevent it beforehand for mothers. For the education institution of fire safety education, fathers demanded it for safety related institutions while mothers demanded it for children education institutions, and the number of times for parent education was once or twice a year for fathers while it was once a month for mothers. For the parent education instructor of fire safety education, fathers demanded safety education experts while mothers demanded infant teachers that completed the safety education course. For the fire safety education method of parent education, fathers demanded Internet searching while mothers demanded seminars or lectures.
