Objectives: The purpose of the study was to investigate the cumulative dental caries rate of pit and fissure sealant in community public health program from 2005 to 2008 follow-up. Methods: The subjects were 4,768 students of 34 elementary schools in Gimcheon. The survey included direct oral examination and cumulative retention rate of pit and fissure sealant from 2005 to 2008. Data were analyzed using PASW statistical package version 18.0 and the level of significance was set at p<0.05. Results: The cumulative retention rate of sealant was 18%, 25%, and 33% after 1 year, 2 years, and 3 years, respectively. In addition, the cumulative retention rate of lower teeth was higher than that of upper teeth. Cumulative dental caries rate increased in sealed group and no sealed group. The cumulative dental caries rate decreased owing to tooth brushing frequency in sealed group and no sealed group. Conclusions: Regular and timely tooth brushing can maintain good oral health condition after tooth sealing. The school based oral health education can prevent loss of sealant and secondary caries.

Identification of gravitational wave (GW) sources in electromagnetic (EM) wave observations is important because it enables us to understand the property of the GW-emitting sources/mechanisms much better than the GW detection. For that reason, a large number of astronomers are working on observations to identify the position and the nature of GW sources. We give a short overview of the expected EM signals from GW sources and the current EM follow-up observations that have been undertaken in Korea and the world.

국제 학업 성취도인 PISA2007, TIMSS 2011에 의하면 우리나라 학생들의 수학, 과학 학업성취도는 최상위에 해당하지만, 관련 태도가 낮다는 결과가 나왔다. 또, 사회에 만연한 이공계 기피현상, 초중고에서 점점 사라지고 있는 정보과학 교육의 현실을 반영하는 학습 경험을 제공해야 할 필요성이 제기되었다. 이러한 필요성에 의해 본 연구자는 2012년에 Physical Computing 기반의 STEAM 프로그램을 개발하고 그 효과를 연구하였다. 그 결과 과학적 문제해결력, 과학적 태도, 인성 등에서 향상되는 결과를 얻었다. 본 연구에서는 2012년 연구의 후속연구이다. STEAM 프로그램을 적용하여 향상을 가져 온 4학년 학생들이 1년 후에 STEAM 교육을 받지 않았을 때 학생들에게 어떤 변화가 생겼는가를 연구하였다. 분석 방법은 4학년 초, STEAM 교육을 받은 4학년말, STEAM 교육을 받지 않은 5학년말의 검사 결과를 비교하였다. 그 결과 과학적 탐구에 대한 태도를 제외한 모든 영역에서 STEAM 교육을 받지 않은 5학년말은 4학년 초에 비해 향상이 없는 결과를 얻었다. 이것은 STEAM 교육의 필요성에 대한 역설적인 증거라고 할 수 있다.

This study investigated the effect of food consumption monitoring and real-time communication-based weight control program using a smartphone on weight reduction and maintenance in obese women. This study consisted of two phases: an 8-week weight control program with food consumption monitoring and real-time communication using a smartphone and an 8-week follow-up. Sixteen obese female college students (>30% body fat) participated in this program, and we measured changes in body composition and dietary intake volume. Follow-up analysis focused on weight maintenance after 8 weeks of no contact. Total energy intake (P<0.01), body weight (P<0.001), percent body fat (P<0.001), body fat (P<0.05), and body mass index (P <0.001) decreased significantly after the 8-week weight control program. However, we could not observe total energy intake or body composition regain after the follow-up period. These results suggest that food consumption monitoring and real-time communication using a smartphone can be effective for weight control and maintenance.

This study proposes to implement premarital education programs designed to enhance potential capacity in marital life, targeted at marriage expectant couple and verify the effectiveness of the programs. For this study, 8 marriage expectant couples residing in Seoul participated. For this study, advance and follow-up surveys were conducted. To be specific, the advanced surveys questions were posed regarding general features, the level of communication, conflict-resolution skills and the attitude toward the role of the gender and so forth of those persons polled. In follow-up surveys, questions were asked regarding the extent to which the participant was satisfied with the contents of the education and teaching process in each session of the programs, the attitude toward the role of the gender, the level of communication and conflict-resolution skills. The effectiveness of the program was verified based on the subjective level of satisfaction of the instructor and the program manager and the statistical analyses of advance and follow-up surveys. Our findings show: First, the changes in 'the attitude toward the role of the gender' of the participants after 'the education of the role of the gender' were not significantly related. Second, after 'the education of communication' was implemented, the capability of the participants to communicate proved to have improved. Third, the extent to which the participants were satisfied with the contents of the education scored higher than the average, the level of educational satisfaction with 'the skills of communication between the husband and wife' scoring the highest. Fourth, with respect to the level of overall satisfaction with the educational effects of the program, the level of satisfaction with improved relationship between each party of the couple turned out relatively high, and the level of the overall education program also proved to be high.

As a new way to explore the universe, astronomers are now performing time-domain astronomy by surveying the universe looking for new transient phenomena and taking movies of the universe with telescopes. Large-area, time-series survey of astronomical objects are uncovering many interesting, fast-changing objects that have now been poorly understood before, such as GRBs, tidal disruption phenomena, and new types of supernova. In order to characterize these new, exciting events, it is very critical to perform follow-up observations, and 1-2m telescopes can effectively contribute to such efforts. Since 2007, our group has been performing follow-up observations of gamma-ray bursts (GRBs) and interesting transients using BOAO and other KASI facilities. Here, we present results from several key transient studies that were done by using BOAO: (1) tidal disruption event Swift J1644+57; (2) SN 2011fe that occurred in M101; and (3) several GRB events. These study demonstrates the usefulness of BOAO as a powerful transient follow-up facility. Finally, we will discuss how BOAO research activities can possibly be bolstered in this newly emerging field of astronomy.

This study was executed to examine the effect of group-psychotheray oriented psychodrama on child's depression. For this study self-reporting Kovacs's children's depression inventory(C.D.I) was administered for primary school children. and 8 children were selected in experimental and control group each. The experimental group acted the psychodrama for 15 session. The first follow-up test was executed at 8 weeks after pre-test and second follow-up test at 10 weeks after first follow- up. Every time children acted the psychodrama all behaviors had been recorded. Also in order to find out any changes in daily life after the psychodrama their parents class teachers and children themselves were interviewed. Basal depression level was 23.38 for experimental group and 23.63 for control group. Depression level of experimental group was reduced to 12.38(p<0.01) There was significant difference in depression level between experimental and control group (p<0.01) Reducing effect of experi ental group by the psychodrama was maintained as well. As a result group psychotherapy oriented psychodrama was effective to reduce depression level of childern. Group psychotherapy oriented psychodrama program for children need to be developed for more effectiveness.

Purpose. This study investigated changes in attitudes toward elders in general and elders with dementia after students finished a gerontological nursing practicum. Methods. Questionnaires developed for Asian cultures were administered pre practicum, immediately post practicum, and at 8-months follow up to 31 senior students in a baccalaureate nursing program. The 1-week practicum occurred at two adult day care centers: a center for elders with dementia and a center for elders with stroke. Repeated measures ANOVA and Bonferroni correction procedures were used to analyze data. Results. Students' evaluation of elder vitality and flexibility increased significantly at post practicum, however this increase was not sustained at follow up. Score of generosity of elders, the only positively evaluated dimension for elders in general, improved partly at post practicum. Students evaluated flexibility and generosity of elders with dementia more negatively than general elders. All of the decreased attitudes at follow up were not significantly different from those at pre practicum. Conclusions. Students had more negative attitudes toward elders with dementia. Attitudes of students in direct contact with elders with dementia were improved through the practicum regarding generosity and flexibility. However the sustainability of the immediate effect was not observed at follow up.
