Triglycerides of cottonseed oil were separated by thin layer chromatography (TLC), and fractionated by high-performance liquid chromatography (HPLC) on the basis of partition numbers. From each fraction, it was fractionated again on the basis of acyl carbon numbers using gas liquid chromatography (GLC). The fatty acids of triglyceride for each partition number group were analyzed by GLC. From, these results, triglyceride constituents of cotton seed oil were estimated to be 37 kinds of triglycerides. The major triglycerides and their contents in cotton seed oil were as follows: 25.8%$(C_{16:0},\;C_{18:2},\;C_{18:2})$, 15.5%$(C_{18:2},\;C_{18:2},\;C_{18:2})$, 13.8%$(C_{16:0},\;C_{18:2},\;C_{16:0})$, 8.3%$(C_{18:2},\;C_{18:1},\;C_{18:2})$, 6.2%$(C_{18:2},\;C_{18:1},\;C_{18:1})$, 4.1%$(C_{18:1},\;C_{18:1},\;C_{14:0})$, 3.4%$(C_{16:0},\;C_{18:1},\;C_{16:0})$, 2.3%$(C_{18:1},\;C_{18:2},\;C_{16:0})$, 2.2%$(C_{18:1},\;C_{18:1},\;C_{18:1})$, 1.0%$(C_{14:0},\;C_{18:2},\;C_{18:1})$.

Given that cognitive demands of mathematical tasks can be changed during instruction, this study attempts to provide a detailed description to explore how tasks are set up and implemented in the classroom and what are the classroom-based factors. As an exploratory and qualitative case study, 4 of six-grade classrooms where high-level tasks on ratio and proportion were used were videotaped and analyzed with regard to the patterns emerged during the task setup and implementation. With regard to 16 tasks, four kinds of Patterns emerged: (a) maintenance of high-level cognitive demands (7 tasks), (b) decline into the procedure without connection to the meaning (1 task), (c) decline into unsystematic exploration (2 tasks), and (d) decline into not-sufficient exploration (6 tasks), which means that the only partial meaning of a given task is addressed. The 4th pattern is particularly significant, mainly because previous studies have not identified. Contributing factors to this pattern include private-learning without reasonable explanation, well-performed model presented at the beginning of a lesson, and mathematical concepts which are not clear in the textbook. On the one hand, factors associated with the maintenance of high-level cognitive demands include Improvising a task based on students' for knowledge, scaffolding of students' thinking, encouraging students to justify and explain their reasoning, using group-activity appropriately, and rethinking the solution processes. On the other hand, factors associated with the decline of high-level cognitive demands include too much or too little time, inappropriateness of a task for given students, little interest in high-level thinking process, and emphasis on the correct answer in place of its meaning. These factors may urge teachers to be sensitive of what should be focused during their teaching practices to keep the high-level cognitive demands. To emphasize, cognitive demands are fixed neither by the task nor by the teacher. So, we need to study them in the process of teaching and learning.

This study was conducted in order to promote students' interest in overseas employment and to present methods of improving education that suits globalization and internalization. From responses to individual written survey questionnaires answered by $3^{rd}$grade 200 students who are studying dental hygiene at colleges in Daegu. They had most interested in Japan (60.3%), and they want to work abroad if they are given the changes (38.1%), which indicate that the dental hygiene majors have much interest and positive attitude in overseas employment. In Japan, there are 158 schools had department of dental hygiene (51 to 2 years, 101 to 3 years, 6 to 4 years). Especially, Kanto area has 25 private schools. When compared Korea and Japan, they similar were curriculum, 39 at 3 years, 44 at 4 years, respectively. The current national board dental hygiene examination system was 200 in total score, and 19 in total subjects. The 9 basic clinical courses including oral anatomy have 100 scores, and the 8 subjects including preclinical course have 50 scores, one dental assistant course have 50 scores. In Japan, 4 years pre-dental hygiene curriculum content provide certificate of dental hygiene after graduation. They provide additionally 'social worker' in Tokyo University, 'teacher in nursing' in Hirosima University. They scheduled the various foundational knowledge and skill such as competencies to communicate effectively, to participate community health program, and to make decisions regarding dental hygiene service.

This study reviewed the planning characteristics of contemporary Japanese middle school architecture on which related studies are insufficient, aiming to obtain new ideas for planning Korean middle school facilities. Fourteen case schools built after 1990s were selected and analyzed. They were divided into learning-living space and other major spaces. The planning characteristics of the case schools are summarized as follows 1) The case schools were classified into two categories, departmentalized classroom type (D type) and usual with variation type (UV type) by school system. These categories can also be the classification standard for basic architectural characteristics in learning and living space of case schools. 2) D type case schools have departmentalized classrooms, home base, media space and teacher's space for learning-living space. D type case schools are divided into 'attached-to-classroom type' and 'separate type' depending on the adjacency of the home base and departmentalized classroom. 3) UV type case schools have multipurpose space around the classroom for learning-living space and can be divided into two types, i.e., 'directly adjacent' and 'separate', depending on the connectivity to classroom of multipurpose room. 4) Specialized classrooms are designed to have the openness to the public and the own characteristics of school subjects strengthened and show the spatial differentiation with connected ancillary spaces. 5) Libraries are designed as complex zones grouped with computer labs, audio visual rooms and multipurpose halls not as a single room and as open plan not with a closed wall. 6) The gymnasium is the basic sports facility with a martial arts room and outdoor pool, which are for after-school activities as well as physical education class. 7) The terrace, balcony and outdoor stairs are frequently used architectural vocabularies as diverse outdoor spaces with a variety of functions.

This study is intended to look into parents' satisfaction of contracting-out system in employer-supported childcare centers. To achieve this, a survey was carried out to 400 parents who use national, public and private employer-supported childcare centers. The results were as follows. First, employer-supported childcare factors were the qualities of childcare environment, childcare program and early childhood teacher in both contracted-out and in-house services. The satisfaction with facility, program, operation and childcare training was improved in good employer-supported childcare factors And the satisfaction with the relationship between these factors could improve the expectation for the use of employer-supported childcare centers. Second, the difference in the operation of employer-supported childcare centers showed that the most preferred size was 50 to 74 children. The contracted-out services was more preferred than in-house services. And the location of on-the-job facility was more preferred than off-the-job facility. As stated above, the preference of employer-supported childcare centers was more raised than that of general kindergartens or childcare centers by an increase in the trend of working child parents' dual income. In other words, small and medium sized childcare centers of some 50 children were more preferred than large scaled childcare centers. Consequently, the retainment of childcare programs, facilities and quality teachers contracted out to professional childcare centers can improve the satisfaction with them.

This study examines children's responses on Audie music activity based on Gordon's Music Learning Method. Subjects of study were 3 five year old children(2 boys, 1 girl) in kindergarten. Data collection drew from participatory observation, researcher journal, the classroom teacher interview. Where more specific data were necessary, video and digital camera recorded. The data were described, analyzed, and interpreted. The main findings in this study are as follows : The children who participated in Audie music activity showed desirable changes in many ways. Their music listening attitude was the one that changed most remarkably. At the beginning activity application, the children were not naturally and could not listen attentively while researcher was singing song without words. Gradually children could listen attentively to the researcher's singing without words. Through the Audie music activity, the children began to think carefully the tone and rhythm of music and to express themselves freely and creatively. At the beginning activity application, the children who showed negative responses and blocked up activity became gradually able to show positive aptitude and to amuse. Also the children who showed passive attitude and no responses became gradually able to react spontaneously.

The purpose of this study was to examine how a therapeutic drumming intervention would impact middle school students with regard to school violence prevention. Participants were all in the third-year class of a middle school in Korea. A school music teacher and a music therapist designed and implemented the program collaboratively, and mainly used dyadic, synchronized, and improvisational drumming based on the Social Emotional Learning core competencies. A total of 65 students participated in a weekly 45-minute program for 10 weeks. Ten participants out of 65 were selected for interviews and the rest of the 55 participants were asked to fill out an open-ended survey. Content analysis of the survey and interviews produced 492 meaningful statements, which were categorized into seven themes: somatic responses to drumming, emotional processing, group cohesion, empathy, relationship with peers, self-esteem, and self-regulation. The findings indicated that dyadic, synchronized, and improvisational drumming may promote prosocial behaviors in students of this age. The author discussed that drumming produces physical input directly from the instruments, which prompts students to identify and empathize with their own or others' emotions. This study therefore suggests that collaborative work between school music teachers and music therapists may positively impact middle school students' prosocial behaviors, as they pertain to school violence in Korea.

Objectives This study aims to build the baseline data for school health care program by analyzing the questionnaires about satisfaction regarding Oriental Medical Doctor's (Korean Medicine) student health and wellness program. Methods The association of Korean medicine doctor in Sung-nam city conducted Oriental Medical Doctor's student health and wellness program for 12 middle schools and 8 high schools in Sung-nam from August to December, 2015. The participating Oriental Medical Doctor visited each school for 8 times during 5 months period, and conducted health consultations, health education classes and Korean medicine treatment for the school students and school employees. Teachers and administrators from the participating schools answered the self-reported satisfaction questionnaires and the satisfaction questionnaires results were analyzed. Results 85 people responded the program satisfaction questionnaires; 69% responders were very satisfied and 28% were satisfied about the program specifically about the student's health check-ups, informatory brochures for the parents, good participation enrollment process. Responders were pleased about doctor's consultations regarding 'Advising students about their general health', 'Ways to cure sick students fast', 'Providing students with useful information about health', and 'Teaching students how to manage their health in a good shape'. 92.94% of participants agreed to the needs of the school health and wellness program. Conclusions One of the fundamental national health policies is to provide students opportunities to maintain their good health. We have developed a successful pilot program called, "Oriental Medical Doctor's student health and wellness program". We got positive feedback from the participating school teachers regarding our program. Further studies based on this study are needed to show the benefit of the program to broaden its use.

Objectives: This study assessed the influences of various factors that are related to youth smoking such as gender, age and type of school, and we wanted to provide supporting data for tailored and effective policy initiatives to reduce adolescent smoking. Methods: A self-report survey was conducted on 14,910 teen-age students who were selected based on the nationwide distribution of students in large and small cities and counties, the gender ratio of the students and the ratio of students attending various type of school at 38 middle and high schools in six representative areas of each province. The survey was handled and managed by a health education teacher at each school. Binary and multinomial logistic regression was used in the analyses. Results: Smoking by adolescents was associated with gender, age and even height. Male high school students tended to smoke more than female high school students, but this differences was not significant for middle school students. The older the adolescents were, the more likely that they smoked, except for the female high school students. Height was meaningful for all adolescents, except for the boys at the vocational high schools. Monthly allowance was significant for all adolescents. School factors such as type of school and the students' school performance were also crucial factors. Attending a vocational high school was strongly related to smoking, especially for girls. Students' school performance and the perceived level of stress were strongly associated with smoking, especially for boys. Home factors such as the relationship with parents and conversation time with family members were closely related to smoking behavior. Knowledge about the health hazard of smoking was also found to be strongly related to adolescent smoking. Conclusions: In conclusion, demographic factors, school factors, home surroundings and the perception on the harmfulness of smoking are strongly related to adolescent smoking behavior, but these differ from gender and type of school.

In this report, we set up a simple device which enabled us to obtain data useful to estimate the relative capacity of thermal energy retention of greenhouse built with various plastic coverings. A box($20cm{\times}20cm{\times}30cm$) framed with flexiglass at the edges and covered with thin plastic films was made, in which were placed a thermostat-controlled nichrom wire heater and a thermal probe made of thermister to monitor temperature changes. A wheaston-bridge type transducer and a chart recorder were used to record the changes of temperature inside the box The data obtained by using the device showed that the relative rate of heat toss through plastic films with identical thickness decreased in the order of PE film>EVA film>PVC film and that IR additives such as fine silica gel improved the insulating power of plastic films. This observations are in well accord with general information, demostrating the feasibility of the device in usefulness for the purpose of screening of various commercial plastic coverings.
