Purpose : The purpose of the present study was to access the prevalence of orthostatic dysregulation(OD) and the frequency of each category for major and minor criteria among elementary school students using the OD questionnaire. Methods : We carried out inquiry by questionnaire as to the frequency of OD among two elementary schools with 725 students, 10 to 12 years of age, residing in Gwangju, Korea. The questionnaire was made according to criteria proposed by the Japan OD Study Group. Results : Of the 725 students(male 390; female 335) questioned, the OD was found in 338 students (53.5 percent). Prevalence of OD in males(59.2 percent) was significantly higher than in females(46.8 percent)(P<0.05). Palpitation with slight exercise(95.9 percent) was the most frequent major symptom. Headaches(85.8 percent) were the most frequent minor symptom among cases of OD. Conclusion : The prevalence of OD in elementary school students in this study(53.5 percent) was higher than in other studies. Contrary to studies from other countries, the male to female ratio was reversed. Because the diagnostic criteria seem to be dependent on subjective reporting of the symptoms, a newer diagnostic system based on more objective findings should be established.

The implant prosthesis of anterior maxilla requires careful consideration in planning. In order to satisfy both esthetic and functional needs of a patient, fusion of intra-oral scan in Cone-beam computed tomography (CBCT) and facial scan can be considered. Bony structures and soft tissues captured in CBCT and occlusal surfaces of intra oral scan were incorporated into personal characteristics from facial scan. The patient had insufficient buccal bone on maxillary anterior area. The maxillary implants could not be placed on the most ideal position. However, the "top down" approach completed by computer-generated arranging of teeth in implant planning and surgery with surgical guide resulted in esthetically and functionally satisfying result regardless of the limitation. Careful diagnosis with digital technique and the usage of surgical guide resulted in successful surgery and esthetic restoration. The temporary fixed prostheses were designed, restored and evaluated. The patient was not satisfied with the first design of temporary prosthesis, which showed uneven space distribution between teeth due to the position of maxillary implant. The design was modified by changing proximal emergence contours and line angle to alter the perceived since of incisors. The patient was satisfied with the new design of provisional restoration. A digital occlusion analyzer (Arcus Digma II, KaVo, Leutkirch, Germany) was used to measure inherent condylar guidance and anterior guidance of a patient to provide a definitive prosthesis.

This study aimed to evaluate the effects of utilizing educational game content for science learning on science-related attitudes. The content was applied to 24 students in an after-school science club at an elementary school in Gyeongsangbuk-do Province followed by a pre and posttest analysis using the Attitude About the Relevance of Science Test and the Creative Personality Test. This study used Tino's Journey, which was developed by the Korea Creative Content Agency and is currently distributed for free through the Ministry of Education to develop nine lessons that include scientific scenarios and concepts presented in the game. The results demonstrated that science lessons utilizing educational game content significantly influenced the science-related attitudes of the students. Among the subdomains, enjoyment of science lessons increased the most followed by the attitude toward scientific inquiry, social meaning of science, and hobby of science. However, the commonness of scientists, acceptance of scientific attitudes, and career in science did not reveal significant differences. This study classified the students into two groups (i.e., high and low, n=12 each) using the Creative Personality Test in advance. This study performed covariate analysis with the score for pre-science-related attitude as the covariate. Result revealed that the scores for science-related attitude significantly differed between the high and low groups. Specifically, the increase in the scores of the low group was larger than that of the high group. Lastly, the study presented implications for the utilization of educational game content in science learning.

The purpose of this study was to provide basic data for improving health promotion behavior by identifying the effects of life stress and coping with stress among nursing college students on health promotion behavior. The data was collected from 352 nursing students in 6 colleges in B and K city, and the data was analyzed with SPSS/Win 23.0. Factors influencing health promotion behavior were school life satisfaction (F=9.18, p<.001), happiness score (F=20.64, p<.001), health status (F=12.40, p<.001), eating breakfast (t=-3.31, p=.001), unbalanced diet (t=-4.20, p<.001), time spent sleeping (F=2.64, p=.049), and exercise (t=5.20, p<.001). In the correlations, health promotion behavior was negatively correlated with life stress (r=-.289, p<.001), but it was positively correlated with coping with stress (r=.539, p<.001). The factors influencing health promotion behavior were stress coping (β=.439, p<.001), happiness score (β=.251, p<.001), exercise (β=.172, p<.001), unbalanced diet (β=.125, p=.002), life stress (β=-.121, p=.005), and eating breakfast (β=.083, p=.046). The above variables explained 46.0% for the health promotion behavior. Thus, in order to improve the health promotion behavior of nursing college students, integrated nursing interventions need to be developed through improving coping with stress, creating a sense of happiness, reducing life stress, and maintaining exercise and good eating habits.
