This study was performed to investigate the consumption pattern of school milk programs for elementary school students. The subjects were 518 students residing in Seoul area. The survey was conducted by using a self-administered questionnaire, and the collected data were analyzed by SAS package. Of the subjects, 88.2% of the students were provided with a school milk program, and the number of the students was higher in male students than in female ones(p<0.05). 81.8% of them drink milk every day from the school milk program. For the degree of satisfaction for milk served in the school milk program, 47.9% of the students were satisfied. An upset stomach after drinking milk and poor taste of milk were the main reasons why milk consumption decreased. Only 30.7% of the subjects perceived that they should drink milk in the school milk program. And the subjects anticipated that flavored milk and yogurt should be served to promote milk consumption in a school milk program. Therefore, a proper food guide and a dairy education program should be developed for elementary school students.

Purpose: The purpose of this study was to examine the current status of home care nursing services provided by community health nurses and to identify barriers to the services. Methods: A cross-sectional survey was conducted with three types of community health care nurses. Participants were 257 nurses, 46 of whom were hospital based home care nurses, 176 were community based visiting nurses, and 35 were long term care insurance based visiting nurses. A structured questionnaire on 7 domains of home care nursing services with a 4-point Likert scale was used to measure activities and barriers to care. Data were analyzed using SPSS WIN 21.0 program. Results: Hospital based home care nurses showed a high level of service performance activity in the domain of clinical laboratory tests, medications and injections, therapeutic nursing, and education. Community based visiting nurses had a high level of service performance in the reference domain. Long term care insurance based visiting nurses showed a high level of performance in the service domains of fundamental nursing and counseling. Conclusion: The results show that although health care service provided by the three types of community health nurse overlapped, the focus of the service is differentiated. Therefore, these results suggest that existing home care services will need to be utilized efficiently in the development of a new nursing care service for patients living in the community after hospital discharge.

Objective: In this study, the dental health care knowledge, dental health behaviors and dental health status of elementary school students were compared and analyzed in the cases of their schools having dental health care center or not one. Methods: The target groups were 167 students of A school (experimental group) where pit-and-fissure sealants, fluoride mouthrinsing, and fluoride gel application were carried out with all grades of students by school dental health care center and 158 students of B school (control group) where fluoride mouthrinsing, for all grades students and pit-and-fissure sealants for the first grade students are carried out but have no the school dental health care center. Results: This study was carried out through the answer sheets and recordings of dental inspection. The findings of this study are as follows: 1. The dental health care knowledge was compared and the results showed that on average 14.2$\pm$2.1 in experimental group and 14.0$\pm$1.9 in the control group were no significantly different (p>0.05). 2. The dental health behaviors were compared and the results showed that the experimental group was significantly different(p<0.05) in terms of the number of times of dental brushing a day, the method of tooth brushing, the time of tooth brushing, the experience of tooth brushing with fluorine, the kinds of snacks and tooth brushing in school after lunch. But there was no significant difference(p>0.05) in the time of tooth brushing and the tooth brushing after eating snacks. 3. The DMF rate was compared and the results showed the significantly difference between the average experimental group and 53.8$\pm$5.0 in the control group(p<0.05). 4. The DMFT index was compared and the results showed the significantly difference between the average 0.6$\pm$2 in the experimental group and 1.4$\pm$1.6 in the control group(p<0.05). 5. The DMFI rate was compared and the results showed the significantly difference between the average 4.2$\pm$8.3 in the experimental group and 9.5$\pm$11.0 in the control group. (p<0.05). 6. The DT rate were compared and the results showed the significantly difference between the average 10.2$\pm$29.5 in the experimental group and 32.4$\pm$44.0 in the control group(p<0.05). 7. The FT rate were compared and the results showed the significantly difference between the average 88.5$\pm$31.0 in the experimental group and 67.5$\pm$44.0 in the control group(p<0.05). Conclusions: Based on the results, above there was no significant difference in dental health care knowledge between both the experimental and the control group. But we discovered that the experimental group is better than the other one in dental health care behaviors and dental health status. Therefore, we could conclude that the school dental health care center efficiently carried out the dental care and treatment. As school dental health care centers did not work out efficiently in terms of their educating on the dental health acre knowledge, the related programs to be developed and supported.

The standards for school library in America affected school library policy in US as well as worlds. The America standards for school library established by NEA for the first time in 1920. After the first standard established, America standards revised about 10 times to accommodate educational and technological changes. The Americas new school library standards 'empowering learners: guidelines for school library media programs' established by AASL in 2009. The guidelines are relevant to the 'standards for the 21st-century learner', 'standards for the 21st-century learner in action'. The guidelines expected to affect US as well as school library policy of worlds. Thus, this study aimed to analyze the 'standards for the 21st-century learner' and 'standards for the 21st-century learner in action'. The standard for 21st-century learner offer vision for teaching and learning to both guide and beckon our profession as education leaders. They will both shape the library program and serve as a tool for library media specialists to use to shape the learning of students in the school. The standards for the 21st-century learner in action offer how are AASL's new learning standards, the standards for the 21st-century learner, incorporated into the school library.

In this study, science history program was developed to enhance student's concepts toward the particulate nature of matter and the understanding about the nature of science. And the effects of its application was investigated in the lesson of ‘Composition of Matter' in middle school science class. This science history program was based on genetic approach and included the contents from the old Greek natural philosophers to Avogadro. Before instruction, the test of understanding about nature of science was administered, and the science scores of the previous course were obtained, which were used as covariates. During 24 class hours, this study was conducted with two classes(experimental and comparison group) in a middle school in Seoul. The experimental group was received lessons by science history programs and the comparison group was received traditional lessons. After instruction, the scientific concept test, the test of understanding about nature of science were administered. The result of this study indicates that the scientific concept scores of experimental group were significantly higher than comparison group at p <.01 level of significance. It means that the students in experimental group has more sound conceptions about the particulate nature of matter and less mis conceptions about matter than the students in comparison group. However, there was no significant difference between two groups in the score of understanding about the nature of science.

The purpose of this study is to explore the effects of a VR(virtual reality)-based biology class on both the cognitive and affective domains by developing and applying a VR-based biology program for 6th-grade elementary school students. For this research, we developed a VR teaching material about 'digestion' reflecting virtual reality characteristics and one hundred five students in an elementary school in an urban area participated in this study and took three VR-based lessons. To examine the cognitive effects of a VR-based biology class, the study subjects were divided into two groups. The experimental group was composed of 50 individuals who participated in VR-based biology lessons, while 55 students of a control group learned through general lessons. We collected data using drawing tasks for measuring students' modeling performance level from these groups and analyzed the cognitive effect of VR-based instruction. We also recorded 21 interviews of students after the intervention, which were transcribed to verify the students' perception of cognitive and affective effects. The key results are as follows: First, we demonstrated the possibility of applying a VR program reflecting VR characteristics (manipulation, multi-sensory, and interaction). Second, we found out that a VR-based biology class significantly enhances higher levels of thinking (spatial, abstract, and reflective thinking). Third, we examined students' perceptions on this program and came to the conclusion that VR characteristics positively affected cognitive and affective domains. This study may be able to contribute to offering guidelines on how to apply VR-programs to future science education effectively.

The purpose of this study was to investgate combined effects of L-carnitine supplementation and exercise on body composition, serum lipids and adiponectin in obese high school female students. Eighteen female students with 35% fat in body weight participated in the study. Students were randomly divided into the following three groups; exercise and L-carnitine supplementation group (ELG: n=5), exercise group (EG: n=6) and control group (CG: n=7), each with seven students. They underwent 10 weeks of exercise (50 min/day, 5 times/wk, 10 wk, RPE 11~16). ELG was given L-carnitine (1 g/day), EG and CG were given placebos. Before and after this period, body composition, serum lipids and adiponectin in plasma were measured. The results of the study in the three groups were as follows: Fat mass and %BF were significantly decreased in ELG. On the other hand, free fat mass was significantly increased in ELG, however, other groups showed no changes. Total cholesterol was significantly increased in the control group. High density lipoprotein cholesterol and low density lipoprotein cholesterol were not different in the three groups. Triglyceride was significantly decreased in ELG. Adiponectin was significantly increased in ELG. This study demonstrated that exercise and carnitine supplementation have a positive effect on fat mass, %BF, free fat mass and adiponetin. Thus, we can improve proper dietary and training programs for obese students.
