School mathematics are composed of five major units of numbers& algebraic expressions, equations & inequalities, functions, figures, and statistics & probabilities. But if we look into the general activities of mathematics teachers in their class, they rather do not take into account students\` cognitive and affective traits or degree of difficulty which each of the unit has. For successful teaching of mathematics, teachers should take into consideration many affective items which influence the students\` scholastic achievement. Among them student\`s liking for the mathematics is commonly accepted as the most important factor for successful learning. In this study, with the five units of school mathematics, we investigated the students\` degree of likings for each unit. To fined out whether there are any differences in students\` likings for the mathematics, between regions and kind of schools, we classified the population according to the locations and kinds of schools. To do this, we divided the whole region into four parts such as Seoul, large city, medium city and town. Moreover, we partitioned the whole secondary school students into four groups of middle school students, vocational high school students, pro-science students of academic high schools, and pro-liberal arts students of academic high schools. From each partition, we sampled similar size of experimental groups which came up to total 1260 students. Analysing the answer sheets which the students responded about the questionnaire, we investigated the following questions using the ANOVA test. 1. Is there any differences in the trend of likings for each unit between the regional classifications? 2. Is there any differences in the trend of likings for each unit between the classifications of secondary schools? 3. What trends of changes are there in the degree of likings for each unit according to the rising of students\` grade?

This study was conducted to investigate the situation of internal facilities and sanitary management of elementary, middle, and high school foodservice in Chonbuk area. Self administered questionnaires were collected from 252 nutrition teachers and school dietitians. Statistical data analysis was completed using a SPSS 11.5 program. The results are summarized as follows: Approximately 99.2% of the subjects were women and those who were married accounted for 76.6%. Those in their 30s to 40s accounted for over 87%, those with more than 11 years experience accounted for 56.8%, and those 69.0% were regular nutrition teachers. Among the 280 school foodservice systems, 51.6% of the schools were located in urban areas and 48.0% in rural areas. About 68% of the schools prepared meals the conventional way and 32.3% prepared them the commissary way. The number of employees accounted for in the schools was 37.7% with 1 to 3 employees, 27.8% with 4 to 6 employees, and 25.4% with 7 to 9 employees. About 54% of schools have an expectance of school meal service for more than 11 years. However 67.5% of their facilities had not been remodeled since the implementation of the foodservice. As a result of the conditions of the school foodservice facilities, there were significant differences between elementary and middle & high schools; preparation room (p<0.01), toilet (p<0.01), and boiler room (p<0.01). About 62% of the nutrition teachers responded that they were dissatisfied with the situation of the facilities (e.g. size and materials of the kitchen, heating and cooling systems). The washing and disinfection methods in elementary, middle and high schools were very different, because they had no sanitizers and disinfectant guidelines. Therefore the governmental regulating agencies must review and approve of the plans prior to new construction or extensive remodeling of the school foodservice facilities. In addition, we suggest that it is necessary to provide practical sanitizers and disinfectant guidelines and other useful education.

Purposes: The aim of this study was to examine the awareness of health education environment, teacher efficacy, and job satisfaction and to identify their relationship. Methods: A total of 193 school nurses from elementary/middle/high schools in Korea were enrolled in this descriptive study. The awareness of health education environment, teacher efficacy, and job satisfaction were measured using structured questionnaires. Results: The awareness on health education environment was $3.10{\pm}.56$ on average. School nurses with positive awareness on the environment showed significantly greater efficacy and job satisfaction than those with negative awareness, and school nurses at elementary schools had positive awareness on the environment compared with those in middle/high schools. Those with work experience of 11 years or more had a positive awareness on the environment. However, heavy workload, lots of work irrelevant to school nursing and few training opportunities on health education were recognized negative items. The awareness on the health education environment was positively correlated with teacher efficacy and job satisfaction, respectively. In particular, the awareness on health education environment influenced teacher efficacy and job satisfaction. Conclusion: Teacher efficacy and job satisfaction should be enhanced through continued improvement of the health education environment to promote the effect of health education.

Purpose: The purposes of the study were to evaluate dietitian's practices for sustainability management and identify barriers of sustainability management at school foodservice. Methods: A total of 220 dietitians working in Daejeon and Chungnam area were surveyed. 187 responses were analyzed for the study. Data were analyzed using SPSS Windows. Results: The respondents were 36% in their 20 s, 38% in their 30 s, 39.6% in elementary schools, 33.7% in middle schools and 26.4% in high schools. Among dietitian's practices for sustainability management, the item with the highest self-evaluation was purchase eco-friendly food (3.75). The category with the highest score was procurement (3.52), by waste management (3.48), production (3.39), menu management (3.36), facility and energy management (3.20), personnel management (3.18), and nutrition education (3.04). In the area of menu management, production management, facility and energy management, nutrition education, and personnel management, scores of elementary school working dietitians were the highest, followed by middle school and high school (p<0.001). The most perceived factor for barriers to sustainability management was principal's indifference to sustainability management (4.10 out of 5 points). ietitian's sustainability management practices and barriers showed a negative correlation. Conclusion: It is necessary to dietitians, employees, and principals' awareness about sustainability management in order to perform effective sustainable management school foodservice.

Recently, there is becoming larger interest in the public practice centers equipped with advanced manufacturing equipment of industries that is difficult to have in all vocational high schools for strengthening practical education and technical education tailored to the Fourth Industrial Revolution in vocational high schools. In this study, using spatial optimization approaches, we explored the optimal location sets of the public practice centers of vocational high schools in Seoul for an illustration. For the proposed optimial location methods, P-median Problem (PMP) and Maximal Coverage Location (MCLP) were used because, when the public practice centers located in priority of large vocational high schools based on the number of students, it showed that the result is not minimizing the travel distance and maximizing the demand of the vocational high school students. This study found that the PMP can find the optimal location sets that minimize the travel distance of whole students. In addition, all students can be captured through locating five public practice centers by MCLP. It should be noted that the optimal locations of this study are limited in Seoul. However, the frame of this methodology applied in this study can be utilized to locate the public practice centers in other regions based on the spatial decision making.

Geometric mean of airborne welding fume concentration at technical high schools was 4.80mg/㎥(N.D∼35.39mg/㎥) and the percentage of samples exceeded TLV of the Korean ministry of labor was 43.6％, Geometric mean of airborne Mn concentration was 0.06mg/㎥(N.D∼0.42mg/㎥) and the percentage of samples exceeded TLV of ACGIH was 15.4％. In case of airborne Mn concentration, there is a significant difference among schools (P＜0.05). Mn concentrations in blood of the exposed and control groups were 1.84$\mu\textrm{g}$/㎗ and 1.91$\mu\textrm{g}$/㎗, respectively. Mn concentrations in urine of the exposed and control groups were 1.36$\mu\textrm{g}$/$\ell$ and 0.57$\mu\textrm{g}$/$\ell$, respectively. In case of Mn concentrations in urine, there is a significant difference between both groups(P＜0.001) and among schools(P＜0.05). Mn concentrations in blood and urine of exposed group were not over BEIs of the Korean ministry of labor. Mn levels in blood and urine were not significantly affected by smoking, drinking and residence. There was no correlation between Mn concentration in air and blood, but there was a statistically significant correlation between Mn concentration in air and urine(r=0.323). There was no a Statistically significant correlation between Mn concentration in blood and urine.

In Korea, the school foodservice program has been expanding rapidly in recent years, partly as a result of increased government support. With the growth in the number of schools offering foodservice programs, food safety and sanitation concerns have been increasing. To assist with program improvement, a situation analysis was carried out, with the focus on equipment and sanitary management of school foodservice programs under flour different management systems. A questionnaire was mailed to the foodservice directors of 234 randomly selected schools chi[h included elementary, middle and high schools at the national level. Among them, one hundred and sixty-five responses reasonably completed were used for the analysis. This study classified each school's foodservice management into one of four types : independent-conventional, independent-commissary, contract-conventional, and contract-delivery. The results show that the monitoring of employees' health and personal hygiene, and employees' sanitary education was well conducted, but that the sanitary education of the voluntary parent workers was largely ignored. Eighty-six percent of the schools had their drinking water tested for sanitation, and the results showed that more effort is needed in careful management of drinking water in order to prevent foodborne illnesses and bacillary dysentery. In general, contract management showed lower scores in foodservice equipment and their efficiency, compared with independent management. A relatively high number of schools on the contract-delivery management system employed nurses and leachers instead of dietitians and foodservice directors. The adoption of the HACCP (Hazard Analysis Critical Control Point) system was lowest in contract-conventional and contract-delivery management systems, and highest in elementary schools using the independent-conventional system.

This paper aims to find out how did elementary students understand scientific units in science textbooks. The subjects were 191 students of the 6th grade from 7 elementary schools in 3 different areas, consisting of 70 from 4 village schools of, 64 from 2 town schools of Gyeongnam province, and 57 from one city school in Ulsan Metro City. A test was developed based on the analysis of scientific units in the science textbooks and teacher's manuals constructed according to the 6th and 7th National Science Curriculum. The understanding of elementary students' on the scientific units(Temperature, Length, Weight, Volume, Speed, Plane Angle) were surveyed. The result are as follows: Regarding the temperature unit, the students generally well understand why to measure and how to read temperature, but had some problem in recording it, in confusion with the plane angle sign. As for the length unit, they obtained high scores in understanding the purpose of measuring length as well as recording and reading it. Which indicates that they are well aware of and use the unit appropriately. With respect to the weight unit, they got high scores in reading and recording weight, which means most students have no problem using the unit. However, it was found that they do not understand why to use the plate balance scale. The volume unit was one in which the students got relatively lower scores. They do not perceive the object of using a scale cylinder and confuse it with a device of length measurement. The unit of speed is the most difficult one for children's of science to understand, presumably, because it is an derived unit from two basic units. It is also assumed that the students got the highest score in the plane angle unit because they studied the unit immediately before the test. From the children's understanding of science units above the teacher's understanding and teaching methods presumed to play a major role for children to understand and use the science units properly.
