The purpose of this study is to develop an astronomical observing education program that enables high school students to inquire the distance of astronomical bodies based on the research methods (observing open clusters and exploring collected big data) using small telescopes and DSLR cameras. After analyzing the 2015 revised science curriculum, we developed science club activity materials and teacher-student learning contents suitable for high school earth science education. A panel of six teachers and researchers of earth science education and astronomy, participated in developing the educational materials. The validity of the program was verified through establishing the agreement among the panels after in-depth discussions and clarifications. The program, developed with 10 lessons in total, showed high satisfactory content validity (CVI, .89) and conformity of school class (Likert's 5 point scales, 4.17). The feedback of the panels and the Delphi analysis continued to improve the quality of the program. The pilot testing result with high school students (N=9) showed that the students' satisfaction rate was high as 4.48. Using the astronomical observational education program of this study is expected to contribute in improving the convergence educational activity, interest, curiosity, and inquiry ability of students in the universe and the astronomical bodies.

The purpose of this study is to analyze components of conflicts and investigate causes of them between mentor teachers and mentee teachers, who participated in the collaborative mentoring program to improve beginning science teachers teaching practice. The most often occurring component of conflict for surveyed teams was class strategy on knowledge of teaching methods. Then, conflicts in understanding student characteristics as a component of understanding students and knowledge transfer of concepts in science as a component of teaching contents followed as main causes. Changes in conflicts showed that less frequency of conflict occurred with ongoing mentoring. Conflicts from class strategy decreased the most, which had been the most often occurring cause. This decrease was explained as mentees were changed gradually into the teacher's role recognition through continuous mentoring. This study suggests that education for mentor and mentee teachers be provided with consideration of causes of conflicts and reasons for those causes, which eventually lead sustainable and efficient mentoring program management.

Although several studies have made and policies have formulated for an increase in women's participation in economic activities, the participation rate of women in economic activities in Korea is only 50% and much lower than in other advanced countries. This study aims to analyze the factors that affect women's continuance intention in economic activities including their motivation for economic activities, women's perception of work, and government support recognition. We empirically analyze and examine such factors and the moderating effects of family support. The survey was conducted on women nationwide to be distributed evenly among various age groups, ranging from those in their 20s to those in their 50s. The results of the empirical analysis based on the data collected on a total of 406 people were as follows. First, the motivation for economic activities including economic and self-realization motivation, women's perception of work, and government support was seen as having a significantly positive effect on women's Continuance Intention in Economic Activities. Second, the impact of women's work perception on their continuance intention in economic activities varied depending on the level of family support, and its moderating effect was confirmed. But there was no moderating effect of family support between economic and self-realization motivation, government support recognition, and the women's continuance intention for economic activities To increase women's continuance intention for economic activities, both support for work-family compatibility policies and institutional support should be provided. Government support will also be needed in order to enable women with abundant experience to participate in economic activities.

The purpose of this study was to investigate students' views on the value of school science lessons and the aspects of science lessons that appeal to students. For the investigation, semi-structured in-depth interviews with 16 secondary school students were conducted. The results showed that about half of the participants thought that science lessons are important, but not all students have to learn science. And they considered only intrinsic interest and career hopes as critical elements in judging the necessity of science education for all. To appeal to students: first, science lessons should have relevance to students' career hopes, interest, curiosity, abilities, real life, experiences, and test scores. Second, they should acquire students' understanding. Third, they should include more experiments. Finally, they should be related to real life, reflect students' interest and concerns, and link new things with what students already know in terms of contexts and contents. Students thought that science lessons are not suitable for students who don't desire to pursue a science-related career. This suggests that present science curriculum perceived by students doesn't match well with the idea of science education for all. To overcome this problem, students need to be included in the debate about the relevance of science curriculum.

It is important to practice preventive method to control oral disease. Dental caries tendency has been decreased in developed countries, but early childhood caries(ECC, BBTD) became serious dental problems in many countries. To slove these problems, more positive and definite prenatal programs on infants and child are needed. Mostly the control of oral health was affected by a mother's knowledge and behavior in this stage. According to many studies, prenatal education is the most effective method to promote oral health in children. But in Korea, there is little oral health education programs for pregnant women, nursing mothers, infants and children. The purpose of this study was to access the knowledge and opinions of caries prevention among gravid women. 330 pregnant women(primiparae=181, multiparae=149), aged 23 to 39 years were randomly selected at prenatal health education courses in Seoul, Korea, 2000. Face-to-Face interviews were conducted by a trained interviewer using questionnaires included demographics, attitude toward children's dental cares, knowledge of early childhood caries, knowledge concerning pregnancy and oral health. The obtained results were as follows; (1) Most respondents were very concerned about their children's oral health. (2) 58% of the respondents were unaware of early childhood caries and the proportion was significantly higher among primipara (p<0.05). (3) Only 43% of the respondents believed that improper breast feeding could develop ECC, the proportion was significantly higher among primipara(p<0.05). (4) 82% of the respondents reportedly believed that the fetus takes away calcium from the mother's teeth during pregnancy. (5) 71% of the respondents believed that dental treatment during pregnancy was unsafe. There is a relatively low level of accurate knowledge regarding infant nutritions, maternal need for oral health and dental caries prevention among pregnant women. Oral health education and promotion programs that are science-based are needed for gravid women.

In order to investigate the factors influencing QOL and life satisfaction of the physically disabled, the author interviewed, by using structuralized questionnaire, 440 individuals among the physically disabled who were participated in Health Examination from April to July, 1997. The questionnaire consisted of the general characteristics(sex, age, marital status, family number, etc), the Reintegration to Normal Living Index(RNLI) to assess QOL, and the single item of five-likert scale to evaluate life satifaction. The means of RNLI were $16.2{\pm}4.8$ in total score, $12.2{\pm}3.4$ in daily functioning and $4.0{\pm}2.1$ in perception of self. The respondents were less reintegrated toward social activities and relationships than impairments or disabilities. While the satisfied group was 47.3%, the dissatisfied group was 52.7%. As the results of multiple regression and logistic regression analysis, the significant predictors of QOL were age, education, job, grade of disability and subjective health status. The life satisfaction were related to economic status, job and subjective health status. To improve QOL and life satisfaction of the physically disabled, it is important that we improve their basic socioeconomic status by getting a job through rehabilitation education and induce them to have positive self-assessment by extending the opportunity of social participation.

Astronomy is the subject that can easily draw students' interest in studying science, therefore plays an important role in developing scientific core competence. However, it is difficult to develop spatial thinking that is required in understanding astronomical concepts through the classroom lessons. Planetarium, along with the science museum, is one of the most representative informal educational institution where astronomical concepts can be taught beyond time and space constraints. In this study, we developed the astronomy education program that is operated in the planetarium and applied the program to the elementary, middle and high-school students to investigate the effects of the planetarium lesson compared to the classroom lesson. The duration of this research was about 8 months, and the number of the students involved is 761, including participants of the 1 night and 2 days camps in the Daegu National Science Museum. The newly developed planetarium lesson is comparable to the previous classroom lesson of which topics are cardinal points, constellation, and the rotation of the earth. Test items were developed to evaluate the understanding of the astronomical concepts. The study was conducted based on the pre- and post-test with non-equivalent groups design comparing classroom and planetarium lessons. The results of this study are as follows. First, planetarium lesson is more effective for understanding astronomical concepts such as the cardinal points, earth's rotation, and the constellation than classroom lesson. Second, planetarium has a positive effect irrespective of gender and previous knowledge. Third, planetarium for high school students has the same effect as additional observation activities followed by the classroom instruction. Therefore, planetarium can be used as an alternative, effective tool when night observation is not available. In summary, planetarium is an effective tool that helps students to understand the astronomical concepts.

For wide application of perilla leaf, which has various healthy functions and can be easily cultured across Korea, the physicochemical and sensory properties of pan bread made with various amounts of squeezed perilla leaf juice (SPLJ) were analyzed. When dough characteristics were analyzed by using farinograph, consistency and dough development time were not significantly different between the control and bread dough made with various amounts of SPLJ, whereas dough stability time increased with increasing SPLJ amount. Expansion rate of dough decreased with increasing SPLJ amount. The volume, specific volume, and baking loss rate of pan bread made with various SPLJ amounts decreased with increasing SPLJ amount. Pan bread crumb colors became thickened and greenish with increasing SPLJ amount. For physical properties of pan bread made with various SPLJ amounts, springiness and cohesiveness decreased with increasing SPLJ amount, whereas brittleness, chewiness, and hardness increased with increasing SPLJ amount. In the sensory strength analysis, pore uniformity and soft texture decreased with increasing SPLJ amount, whereas crumb color (dark greenish), perilla leaf odor, perilla leaf taste, and chewing texture increased with increasing SPLJ amount. In the overall acceptance analysis, 1.5% SPLJ was the most preferred with a score of 7.10. However, statistical differences between 1.5% and 1.0% SPLJ were not detected at P<0.05. In the partial least squares analysis, consumers liked bread with a green crumb color, perilla leaf odor, perilla leaf taste, and soft and chewing texture. In conclusion, physicochemical properties of pan bread made with SPLJ were less desirable than those of the control; however, consumer acceptance of pan bread made with 1.5% SPLJ was shown the highest. Therefore, methods for increasing physicochemical properties of pan bread made with SPLJ need to be developed for wide application of perilla leaf.

Purpose: In terminal cancer patients, pain control with narcotic analgesics and supportive care by hospice are very useful treatment modality. However, many patients and their caregivers are poorly compliant in using narcotic analgesics for fear of addiction and tolerance. And also many patients and family caregivers are reluctant to accept hospice, presuming that hospice means patient's condition is no longer reversible and progressively deteriorating. The purpose of this study was to evaluate and analyze the perception of using narcotic analgesics and hospice by family caregivers of terminal cancer patients who play a critical role in health care in Korean culture. Methods: A total of 54 terminal ranter patient's family caregivers participated in this study. Questionnaire consisted of 15 questions about narcotic analgesics and hospice. Results: The study revealed following results. 1) family caregivers who are not aware of hospice are more than half (56.7%). 2) 81.8% of family caregivers agreed that hospice care is beneficial to terminal cancer patients. 3) 85.1% of family caregivers were under financial burden. 4) 83.2% of patient complained pain in 24 hours. 3) while 88.5% of family caregivers believed that narcotic analgesics can control pair, 79.1% and 79.6% of them also believed that use of narcotic analgesics would result in addiction and tolerance, respectively. Conclusion: There still exist barriers to family caregivers in using narcotic analgesics for pain control. And also, terminal cancer patient's family caregivers have poor information about hospice. Therefore, educational intervention about narcotic analgesics by pharmacist and doctors are needed for proper pain control for terminal ranter patients. In addition, more precise information about hospice care should be provided for terminal cancer patients and their family caregivers.
