This study was to examine whether musically talented adolescents' passion and achievement goals influence their deliberate practice. Of the musically talented adolescents surveyed from two arts high schools in Seoul, Korea, 597 completed and returned the questionnaires. Their average age was 17.4 years. Paired t-test on musically talented adolescents' passion(i.e., harmonious passion, and obsessive passion) and achievement goals(i.e., mastery goals, performance-approach goals, and performance-avoidance goals) indicated that harmonious passion were higher than obsessive passion. Mastery goals were higher than performance-approach goals. And performance-approach goals were higher than performance-avoidance goals. Independent t-tests were measured between high and low deliberate practice(DP) groups. High DP group showed higher harmonious and obsessive passion, and mastery and performance goals than low DP group. It was also found that two types of passion(i.e., harmonious and obsessive) positively influenced on deliberate practice via mastery goals.

The purpose of this study was to investigate the effects of leisure-based occupational therapy on leisure satisfaction, activities of daily living, and rehabilitation motivation in elderly patients with chronic diseases. In the study, Subjects were assigned to either the control or experimental group. The experimental group consisted of 10 and the control group of 14 patients. The experimental group receive a Leisure-based occupational therapy intervention, and the control group receive a conventional occupational therapy intervention. Leisure satisfaction, activities of daily living, and rehabilitation motivation were measured to Canadian occupational performance measure(COPM), Korean Activities of Daily Living(K-ADL·K-IADL), and Patient Questionnaire of Rehabilitation Motivation(PAREMO). Evaluation scores were compared before and after intervention to determine whether or not there were differences over time. And we examined the correlation between the variables. The results of this study were as follows: 1) The leisure-based occupational therapy has a significant effect on leisure satisfaction and rehabilitation motivation(p<.01). 2) The conventional occupational therapy has a significant effect on activities of daily living(p<.01). 3) There was a significant correlation between ADL and IADL(p<.01). 4) There was a significant correlation between leisure satisfaction and Rehabilitation Motivation(p<.01). Implications for occupational therapy include that we must offer appropriate approach with considering the interests and value of patients to them. And proposing studies to demonstrate the efficacy of occupational therapy approaches.

The purpose of this study was to investigate the priority of menu management by importance-performance analysis (IPA) of school foodservice menu attributes. Questionnaires were distributed to 448 school dietitians with an official letter, and a total of 292 responses were used for analysis. From the 21 menu attributes, the factors of 'nutrition', 'educational effect', 'capability consideration', 'ease of quality management', 'efficiency', and 'preference of students' were induced from exploratory factor analysis. The levels of importance (p<0.01) and performance (p<0.05) of the 'nutrition' factor were significantly higher with nutrition teachers than school dietitians, while the importance of the 'preference of students' factor showed significantly higher score with school dietitians (p<0.05). As a result of gap analysis for IPA, only the 'efficiency' factor was located in the area where performance was higher than importance, whereas no menu attribute factors were included in the 'concentrate here' area by the usual IPA. Further analysis showed that there should be more effort to improve the performance of an 'educational effect' factor for a school foodservice menu.

An Isolation-with-Migration (IM) model is used to estimate extant population sizes, the splitting time of populations split away from their common ancestral populations, and migration rates between the extant populations. An evolutionary model such as IM models is estimated by analyzing DNA sequences sampled from the extant populations in the model. When a true model includes an unsampled 'ghost' population without data, the unsampled population is often ignored from the evolutionary model to infer. In this paper, we conduct a simulation study to investigate the effect of an unsampled population on the estimation of the size of the sampled population. When there exists an unsampled population that shares migrations with the sampled population, the size estimation of the sampled population was biased. However, the size estimation was improved if an evolutionary model, including the unsampled population, was estimated.

Objective：In this study, we hypothesized that deficit in processing rapid linguistic stimuli is at the heart of Reading Disability(RD) and deficit in response inhibition is at the heart of Attention Deficit/Hyperactivity(ADHD). We conducted experiments to identify the core cognitive characteristics of children either with RD or with ADHD or with both, using attentional tasks and phoneme differential tests. Method：In the study 1, 28 children with ADHD, 16 children with RD+ADHD were individually administered visual/auditory performance tests. Then, the differences of performance on attentional tasks between two groups were compared while IQs of two groups were controlled. In the study 2, 13 children with RD+ADHD/RD, 13 children with ADHD, and 13 normal children were administered computerized phoneme differential tests. Result：Visual attentional tasks did not distinguish an ADHD group from a RD+ADHD group. With auditory attentional tasks, however, the comorbid group showed significantly more difficulties, causing a large variance in reaction time. RD, RD+ADHD, and ADHD groups showed more errors in phoneme differential tests than a normal control group, and each group showed distinctive performance patterns. Discussion：An ADHD group had difficulty in response inhibition and sustained attention, and children who also had RD along with ADHD magnified the auditory attentional difficulties. Even though children with RD had more trouble with responding correctly to target stimuli, their responses were not significantly different from those of children with ADHD.

This study aims to verity effects of project method on the girl students' task performance ability in the unit of 'Energy and Transportation Technology' of Technology' Home Economics Subject in High schools. The task performance ability are composed of collecting information, performing achievement, planning of solving the task, and performance evaluation. The results of this research conducted for girl students of two classes of H high school located in Gyeong-gi Province are as follows: First, the group with the project method was more effective, in general, in learning ability of performing the tasks of 'Energy and Transportation Technology' than the group with traditional teaching. Second, the group with the project method was more effective than the group with traditional teaching in ability of task performance of subordinate elements of performing tasks in the unit of 'Energy and Transportation Technology', such as collecting information and performing achievement. However, in the fields of another subordinate elements of planning of solving the task and performing evaluation, the degree of effectiveness was unknown. After examining the results of all the cases, it was found that project method was more effective than the traditional teaching method in increasing the performing task abilities of the students in the lesson of 'Energy and Transportation Technology' in high schools.

빙산 질의란 대용량의 데이터에 대해 집단 함수를 수행하여 특정 임계값 이상인 데이터를 결과로 반환하는 연산을 의미한다. 빙산 질의는 도메인의 크기가 대단히 큰 다차원, 대용량의 데이터에 대해 적용되므로 집단 함수의 수행을 위한 카운터를 전부 메모리에 적재할 수 없는 상황이 발생한다. 이 논문에서는 빙산 질의에 대한 저장뷰를 통해 효율적으로 빙산질의를 수행하는 방법을 제시하였다. 빙산 질의의 임계값이 저장뷰 내에 포함되는 경우에는 즉각적으로 결과를 돌려줄 수 있으며, 그렇지 않음 경우에도 표본추출 대신 저장뷰를 사용함으로써 빙산 질의 중간 단계의 후보 수를 크게 감소시키고, 질의 수행 시간 또한 단축시킬 수 있다. 또한 순위 빙산 질의를 수행하는 방법을 제시하여 사용자로 하여금 보다 직관적인 질의를 작성할 수 있도록 하였다.

In this study, we investigated the cognitive characteristics of low science achieving middle school students in K-WISC-IV, and compared the results with high science achieving and achieving students. The results showed us that high science achieving students scored higher than counterparts in FSIQ. Low science achieving students scored lower than high science achieving and achieving students in VCI. Especially low science achieving students scored lower than two groups in subtest SI. The low level of abstraction in low science achieving students is due to the lack of scientific reasoning ability. Therefore subtest SI is considered as highly discriminating test for low science achieving group. Low levels in verbal comprehension, abstraction and reasoning ability are the major factors in poor school performance. High science achieving students scored more than achieving and low achieving students in WMI. Because the working memory is involved in scientific reasoning problem solving process, it is believed to play an important role in science achieved.

The purpose of this study was explored the effect of Flipped PBL on Communication and Problem Solving skill of University students. For study, students in the college of education at A University and S University located in Gyeonggi-do were set up 60 students. They majored in Christian education and early childhood education, and the level of education was similar in the same region and department. In the experiment, the comparison group and the experimental group were separated, and data were collected through pre-test before class and post-test after class, followed by analysis covariance(ANCOVA). Between the comparative group performing flipped learning and the experimental group performing flipped PBL, the problem solving ability and communication ability using the flipped PBL averaged 4.28 and the communication ability averaged 4.06. As a result, it was higher than each of the comparison groups, confirming that it had a significant effect. This will be able to present a flipped PBL class design as an alternative method to overcome the limitations of the existing flip learning in a changing classroom situation and to improve the communication and problem solving ability of the learner.
