Objectives : Dementia has rapidly increased with the prolongation of life expectancy and aging in Korea. This study was conducted to estimate the prevalence of, and find related factors for, dementia in an urban elderly population, using a newly developed screening method. Methods : Seven hundred and six people, aged over 65 years-old, in Dong district of Gwangju, Korea, were recruited using stratified cluster sampling, and completed Korean version of Geriatric Mental State Schedule B3 (GMS B3-K), the Korean version of the Community Screening Interview for Dementia (CSID-K) and modified 10 word list-learning from the Consortium to Establish a Registry of Alzheimer's Disease (CERAD). Dementia was diagnosed by an algorithm derived from all three of these measures. Results : The crude and age adjusted prevalence rates of dementia were 13.0 and 11.5%, respectively. Age, education, marital status and a history of cerebrovascular disease were identified as factors related with dementia. Conclusions : The new instrument, using the GMS B3-K, CSID-K and modified 10 word list-learning from the CERAD, was considered effective as a community screening and diagnostic tool for dementia. The results of this study can also be used to develop a community-based prevention and management system for dementia in the future.

This study aims at analyzing the course selecting standards of college students including Electives and Major courses. For the purpose of this study, we developed a survey through analyzing previous related-research and conducting interviews and pilot study. Using our survey questions, on- and off-line survey was conducted for 301 college students from November 1st to December 5th. As a result of the survey, college student's course selecting standards consist of five factors including 'convenience in learning', 'characteristics of instructors', 'practicality of courses', 'expectations of and interests in learning', and 'external factors.' With the result of factor analysis, we analyzed course selecting standards of college students divided into Electives and Major courses. For electives, 'convenience in learning' was most considered among five factors, followed by 'expectations of and interests in learning', 'external factors', 'characteristics of instructors' and 'practicality of courses.' On the other hand, 'characteristics of instructors' was the highest consideration of college students when selecting courses in Major subjects, followed by 'convenience in learning', 'expectations of and interests in learning', 'external factors' and 'practicality of courses.' This study examined what standards affect college student's course selection, considering Electives and Major courses respectively. We suggested further study on how college students select their courses and how this affect their satisfaction with college education.

Objective : Recently, robotic-assisted spine surgery (RASS) has been considered a minimally invasive and relatively accurate method. In total, 495 robotic-assisted pedicle screw fixation (RAPSF) procedures were attempted on 100 patients during a 14-month period. The current study aimed to analyze the accuracy, potential risk factors, and learning curve of RAPSF. Methods : This retrospective study evaluated the position of RAPSF using the Gertzbein and Robbins scale (GRS). The accuracy was analyzed using the ratio of the clinically acceptable group (GRS grades A and B), the dissatisfying group (GRS grades C, D, and E), and the Surgical Evaluation Assistant program. The RAPSF was divided into the no-breached group (GRS grade A) and breached group (GRS grades B, C, D, and E), and the potential risk factors of RAPSF were evaluated. The learning curve was analyzed by changes in robot-used time per screw and the occurrence tendency of breached and failed screws according to case accumulation. Results : The clinically acceptable group in RAPSF was 98.12%. In the analysis using the Surgical Evaluation Assistant program, the tip offset was 2.37±1.89 mm, the tail offset was 3.09±1.90 mm, and the angular offset was 3.72°±2.72°. In the analysis of potential risk factors, the difference in screw fixation level (p=0.009) and segmental distance between the tracker and the instrumented level (p=0.001) between the no-breached and breached group were statistically significant, but not for the other factors. The mean difference between the no-breach and breach groups was statistically significant in terms of pedicle width (p<0.001) and tail offset (p=0.042). In the learning curve analysis, the occurrence of breached and failed screws and the robot-used time per screw screws showed a significant decreasing trend. Conclusion : In the current study, RAPSF was highly accurate and the specific potential risk factors were not identified. However, pedicle width was presumed to be related to breached screw. Meanwhile, the robot-used time per screw and the incidence of breached and failed screws decreased with the learning curve.

With the digital transformation of the entire industry, software competency has become the core competency for the future talent. However, it is difficult to find researches related to the corporate education for improving employee's software capability. Therefore, this study tried to verify the relationship between factors affecting the learning performance of employees in online software education. For this purpose, a survey of 223 employees with online software education experience was analyzed using the SPSS PROCESS macro. As a result of analysis, perceived usefulness and self-regulated learning have been found to have a significant multiple mediating effect on learning performance by digital literacy and satisfaction. This suggests that not only learner factors but also the characteristics of education should be considered. The results of this study are expected to be helpful in designing effective online education programs.

Korean students ranked the 3rd out of 32 participating countries in the first cycle of PISA(Programme for International Student Assessment) science field, which assessed 15-years-old students' scientific literacy. PISA developed several variables such as parents' socio-economic status, parents' educational attainment, family wealth, and cultural possession, to investigate the effects of background variables on scientific literacy. On the other hand, motivation and engagement in science study were not given much attention, partly because science was the minor area in the first cycle of PISA. Therefore, PISA Korea developed a series of variables to collect data on students' learning motives and out-of-school activities in science as a national option. The results are as followings. First, Korea was found to be one of the PISA participating countries with the scientific literacy achievement least influenced by parents' socio-economic status, family wealth, and parents' cultural possession. Second, the degree of achievement in scientific literacy according to parents' educational attainment was in a positive correlation, similar to the overall tendency of PISA. Third, the most crucial learning motive for Korean students was their desire to develop scientific thinking abilities or obtain science knowledge. On the other hand, choosing jobs in the field of science or parental expectation was the least important learning motive. In particular, the motive for scientific learning was found to have a positive relationship with the degree of scientific literacy achievement. Therefore, the higher the students achievement, the stronger the motive for scientific learning in order to develop their ability to think scientifically or acquire science knowledge. Fourth, Korean students were shown to participate very little in out-of-school scientific activities other than watching TV programs related to science. Whatever the activities may be, the more actively involved students are in out-of-school scientific activities, the higher their scientific literacy achievement. Fifth, Korean girls were rather passive compared to boys in all areas, including science learning motive and out-of-school scientific activities. The gender difference was especially more pronounced in out-of-school scientific activities with wider gaps in such activities as reading scientific books or articles and visiting science-related web sites.

The purpose of this study was to survey the students' career choice related to science. Important factors of career choice were identified through factor analysis. 'Perception of career related to science', 'preference for science learning' and 'participation in science-related activity' were three main factors of science-related career choice. Students' responses to the three main factors were compared according to their career choice, grade and gender using ANOVA. Regression analysis was adopted to find out the relative importance among the three main factors. The subjects were 947 grade 6, 9 and 11 students in Seoul. Numbers of boys and girls in each grade was almost same. The questionnaire was developed to know the factors of students' science-related career choice after preliminary research and literature survey. The ratio of science-related career choice was not high (26%). Students' responses to and the relative importance of the three main factors differed with the grade and gender. From the results, making students have preference for science and giving them more opportunities of science-related activity is more important than making them have positive perception of science-related career. It is required to make a material for science career education considering the differences of age and gender using this study results.
