The purpose of this study was to analyze the food service management practices and productivity in 49 elementary schools in the Daegu and Gyeongsangbuk-do areas. Survey questionnaires were used to obtain a variety of quantitative and qualitative information, including general food service management and productivity, on elementary school food service systems. Descriptive analysis, $\div$2-test, t-test and one-way ANOVA analysis were used as the statistical methods in this study. Eighteen elementary schools were located in urban areas, 13 in provincial areas and 18 in isolated areas. The average number of meals was 565.1, with a significant difference (p＝0.001) between the areas. The average cost per a meal was 1151.0 Won, with a significant difference (p＝0.001) between the areas. The productivity Index (meal/hour) was 13.5, with a significant difference (p＝0.001) between the areas. There was a significant positive correlation of the productivity Index between the total number of meal, the number of employees, the total food cost, meals per employee and the employee's working period. There was a significant negative correlation between the productivity Index and the number of side dishes, the lost per meal, the labor cost per meal and the employee's job satisfaction degree index (JDI).

In this study, we analyzed types of explanation on osmosis concept that were represented in chemistry and biology textbooks of high school and college. There were 5 types of explanation on osmosis concept. The types of explanation were diffusion of solvent, collision, hydration, equilibrium of concentration and screen of holes. Last two types of explanation were classified into misconceptions. The various types of explanation on osmosis concept might cause to have be a reason that students had many misconceptions and to feel difficult to learn about osmosis concept. Many of textbooks is accord to types of concept explanation and figure explanation on osmosis but some is not.

The primary school library make high using convenience of teachers and students and support work of teachers efficiently because of transmission education and information fundamentally. Generally, the main purpose of space composition is economic Lay-out of space and furniture to connect faculty of between space and space. Therefore, to convenient for users and high effect of education, Lay-out of space and furniture, we survey and analyze Lay-out type of faculty space in primary school library. To this aspects, the purpose of this study is to understand state and analyze the occupancy character of space for students that user of primary school library then when we plan primary school library, accomplish more efficient space plan that specialization, pluralistic, individuality of primary school library and cope with environment of education and change of society actively.

A school library is where students develop their skills to cope with future uncertainty and can utilize various information materials to build their capability and response abilities to changes. Teachers' perception is crucial as their guidance is essential for the student to use the school library. Most studies, however, focused on quantitative measurement of the importance of the teachers' perception as an external environment, and there is a lack of specific categorization of different types of perceptions on the role of the school library. This study aims to examine types of perceptions about the school library among elementary school teachers. To do so, this study used Latent Profile Analysis (LPA), a person-centered approach, to identify teachers' complex perceptions about the role and importance of the school library, which were difficult to review in previous studies, and the teachers' most representative types of perceptions. Based on the findings from the above, this study is meaningful in proposing customized measures to operate and promote the school library depending on teachers' perceptions.

This paper examines the relationship between education and marriage in South Korea, based on a 2 percent data of the 2000 census. The result found strong educational homogamy and wife-hypergamy over the five age cohort, 21-30, 31-40, 41-50, 51-60, and 61-70. For the primary, junior secondary, upper secondary and tertiary educational levels, the chance of marrying within the same educational level was stronger for primary and tertiary education. In terms of trends, the educational homogamy increased across the four cohorts. We note that while upward marriage was stronger for women (hypergamy), it decreased over time.

The purpose of this study is to analyze and evaluate the characteristics of online catalogs' interface of elementary school libraries, and to propose how to design user-friendly interfaces. The online catalogs of elementary school libraries are categorized into 6 types. Such topics as the features of search methods, the record display formats, the terminology usage, and the special features of the 6 types are discussed. Some shortcomings are examined and how to improve them is suggested.

This study has been conducted to identify the types and longitudinal changes in the career values of students in science core school. Data collected from 174 students in science core school were analyzed using 11 career value items. First, this study found that there are three types of career value shown in students in science core schools. Second, the career value of students in science core school did not differ by their track. Third, many students of science core high schools have little or no change in their career value values depending on the time of collecting data. However, some students show rapidly changing career values. These findings suggest the need for individualized career education based on the changing trend of students' career values.

The purpose of this study is to explore the structural relationships among parents' educational involvement and parental efficacy on students' school life satisfaction and school achievement and to determine whether there are any differences depending on family type and school level. Using data from 2,497 families that participated in the 2018 National Survey on Children's Life, t-tests and structural equation modeling were conducted. The results of this study demonstrated that two-parent families reported higher levels of educational involvement than single-parent families and custodial grandparent families. Also, two-parent families raising children in elementary schools showed higher educational involvement than two-parent families raising children attending middle schools. Second, parental efficacy was found to mediate the effects of parents' educational involvement on students' school life satisfaction and school achievement. Third, the path coefficients between parents' educational involvement, students' school life satisfaction, and school achievement showed statistically significant differences depending on family type, with two-parent families having greater involvement than single-parent families and custodial grandparent families. Fourth, multiple group analysis reported a statistically significant difference in the relationship between parents' educational involvement and school achievement as well as parental efficacy and school achievement depending on the school level.

This study is to investigate how much highschool students, who have learned functional concepts included in the Middle school math curriculum, understand chapters of the function, to analyze the types of errors which they made in solving the mathematical problems and to look for the proper instructional program to prevent or minimize those ones. On the basis of the result of the above examination, it suggests a classification model for teaching-learning methods and teaching material development The result of this study is as follows. First, Students didn't fully understand the fundamental concept of function and they had tendency to approach the mathematical problems relying on their memory. Second, students got accustomed to conventional math problems too much, so they couldn't distinguish new types of mathematical problems from them sometimes and did faulty reasoning in the problem solving process. Finally, it was very common for students to make errors on calculation and to make technical errors in recognizing mathematical symbols in the problem solving process. When students fully understood the mathematical concepts including a definition of function and learned procedural knowledge of them by themselves, they did not repeat the same errors. Also, explaining the functional concept with a graph related to the function did facilitate their understanding,
