The purpose of this research was to investigate the comparison of core muscle activities according to different performance in static Plank exercise. Ten "J" University's males(age, 23.20±0.65 years; height, 174.54±1.51 cm; body mass, 70.00±2.24 kg; and BMI, 22.94±0.51 kg/m²) completed this study as the subjects. Four type's static Plank motions were performed(full Plank, FP; elbow Plank, EP; side Plank, SP; reverse Plank, RP). For the EMG analysis, we measured the core muscle activities of right side on the rectus abdominis(RA), external oblique(EO), latissimus dorsi(LD), and erector spinae(ES). This research's results were as follows. LD and ES muscle activities were greatest during RP(p<.001). RA and EO muscle activities were greatest during EP(p<.001). Therefore, this results are anticipated to serve as basic data for static Plank performance applications in effective exercise programs.

The purpose of this study is to examine the relationships between process variables, personality traits, intrinsic/extrinsic motivation and their mathematical creativity and how much these factors affect this creativity. These results show the major factor in mathematical creativity as being the gender difference between the gifted male and female middle school students. This also suggests that the education and living guidance of both gifted male and female students should take a different direction in relation to their gender differences in middle schools. In conclusion, all of the normal intellective and non-intellective factors, as well as home process variables, are the basic major data concerned with the effects of mathematical creativity. So, it is with all of this research that the proof for researching synthetically via a new creative research model can be offered.

This study seeks to analyze how children's moral emotions affect their social competence. Moral emotions focus on empathy and sympathy. The purpose of this research is to offer basic data for establishing both amoral and emotional educational program. The subjects of this research involve 182 children(either 4 or 5 year olds) that have lived in Korea. Analysis of the collected data have yielded some interesting results. First, it is found that children's empathy and sympathy are dependent on children's age and their fathers' educational level; as a result, increasing the age of the children and their fathers' educational level are found to increase empathy and sympathy. Secondly, both empathy and sympathy scores are found to have correlation to the scores of positive reciprocity, capability, and interpersonal relation on social competence. Sympathy scores increase with respect to the leadership scores of social competence. Lastly, children's empathy is a factor that affects positive reciprocity, capability, interpersonal relation, and participation on social competence. Their sympathy affects leadership on social competence. The results of this study suggest that strengthening the empathy and sympathy levels of children could partially enhance their social competence.

In the homepage of 16 municipal provincial office of education, school information service displays text-based results through search step or presents the simple information of the selected area when an area is clicked on the static image map. And it has several problems such as server load and slow transfer speed by the search of the synchronous transfer. Thus, in this study, we used the open API of Google map to provide location-based school information and implemented the mash up service for school information with the Ajax program of asynchronous transfer to reduce server load and to increase transmission speed. This service gives the efficiency and convenience to students, teachers, parents and education family members of various levels because it includes the location with school information on a dynamic map.

본 논문에서는 부쉬 트리를 할당 트리로 변환한 후 결합 연산을 수행하면서 실제 실행시간을 동적으로 계산하고 그 결과에 의해 실시간에 프로세서를 할당하는 동적 프로세서 할당 기법을 이용한 파이프라인 해쉬 결합 알고리즘을 제안하였다. 프로세서를 할당하는 과정에서 초기 릴레이션의 기본 정보만을 이용하여 미리 프로세서를 할당하는 기존의 정적 프로세서 할당 기법은 정확한 실행시간을 예측할 수 없었다. 따라서 본 논문에서는 할당 트리 각 노드의 실행결과를 포함한 결합 과정 중의 정보를 다음 노드의 실행시간에 충분히 반영하는 동적 프로세서 할당 기법을 제안하였으며, 이로써 프로세서를 효율적으로 분배하고 전체적인 실행시간을 최소화하였다. 또한 전체적인 질의 실행시간을 줄이기 위하여 결합 가능성이 없는 튜플들을 제거한 후 결합 연산을 수행할 수 있도록 해쉬 필터 기법을 이용하였다. 결합 연산을 수행하기에 앞서 모든 결합 속성 값에 대해 해쉬 필터를 생성하는 정적 필터 기법은 모든 결합 연산의 중간 결과로 발생할 수 있으나 최종 결과 릴레이션의 튜플이 될 수 없는 튜플들까지도 모두 추출이 가능하다. 따라서 각각의 결합 연산 직전에 해쉬 필터를 생성하는 동적 필터 기법에 비해 결합 가능성이 없는 튜플을 최대한 제거할 수 있으며 이로써 결합 연산의 실행비용을 크게 줄일 수 있었다.

The purpose of this study was to investigate the impact of a teacher's leadership (initiating and consideration), class climate, and friendship on academic attitudes. In order to accomplish this, 1,533 elementary school students were recruited. Descriptive statistics and path analysis were employed to examine relationships. The major findings of this study are as follows. First, there were positive correlations between academic attitudes and the teacher's leadership, class climate, and friendship. Second, results of path analysis illustrated that a teacher's leadership consideration indicator had a direct impact on class climate, friendship, and academic attitudes. Furthermore, the teacher's leadership consideration indirectly affected academic attitudes through mediation of class climate and friendship. However, the teacher's leadership initiating indicator did not have a direct impact on class climate, friendship, and academic attitude. The indices of the best fit model for these variables were adequate (GFI, NFI, CFI > 0.90). This study shows that the teacher's leadership consideration is the significant predictor for elementary school students' class climate, friendship, and academic attitudes. Finally, the meaning and limitations of this research, and its implications on academic assistance and intervention, are discussed in detail.

The objective of this study is to determine the structural relationships among the infant's temperament, father's involvement in child-rearing, and the infant's social and emotional behavior. To this end, research was conducted with 330 parents of infants aged 1 and 2 in 55 day care centers located in J city and I city, Jeollabukdo. Frequency analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and structural model equation analysis were conducted using SPSS 21.0 and AMOS 21.0. First, the results of the structural model equation analysis showed that the infant's temperament had a negative correlation with leisure and guidance, while it had a positive correlation with activity and impulsivity, which are external manifestations of their social and emotional behavior. Father's involvement in child-rearing had a negative correlation with the adaptability and mood aspects of the child's temperament, and also with general anxiety, an internal aspect of his or her social and emotional behavior. Social and emotional behavior had a positive correlation with the approach avoidance aspect of the infant's temperament. Second, according to the results of the analysis of the route between the variables, infant temperament was found to be a significant route, having a statistically negative correlation with father's involvement in child-rearing. The results of this study showed that infant's temperament and father's involvement in child-rearing had effects on the infant's social and emotional behavior, and suggested the importance of having a proper understanding of the educational implications of the father's involvement in child-rearing, in terms of its effects on the infant's social and emotional behavior.
