The purpose of this study was to determine the effect of gait training based on the way in a speed pattern on the respiratory function of general adults. A total of 37 people were divided into three groups to conduct fast, standard, and interval gait training. For gait training, a treadmill was used. Three groups were trained for 60 minutes, three times per week, for a period of 6 weeks. Inspiration pressure, maximum inspiration volume, and the size of diaphragm movement were measured. Repeated Measures ANOVA was used to compare times, groups, and interactions. For inspiratory pressure, maximum inspiration volume, and size changes in diaphragm movement, there were significant differences depending on the time and interaction between times and groups. For size changes in diaphragm's movement, there was a significant difference between interval gait training group and standard gait training group. Therefore, interval gait training had effects on size changes in diaphragm movement.

This study has been made to research on the brain wave characteristics of baduk expert by BCI(Brain Computer Interface). The test was based on the researches from 1th September, 2005 to 30th December, 2005, compared with the ones of the standardized general public. The number of the general public are 695 (elementary school students 423, middle and high school students 161, adults 111) and the number of the baduk players are 57 (researchstudents 15, Korean baduk club students 16, professional baduk players 26). The research data show that the baduk players have the higher indexes than the general public in Self Regulation quotient p=.002, Attention Quotient(left) p=.002, Emotion Quotient p=.027, Stress Quotient(left) p=.002 and Brain Quotient p=.006. There are some differences in brain functions between baduk players and the ordinary people. Difference in functions of the brain among baduk experts is also analyzed. That result shows that there is no different brain function between professional baduk player.

The present study attempted the segmentation of the art gallery visitors on the basis of leisure lifestyles. For this purpose, leisure lifestyle surveys were administered at Korea's three representative art galleries, the National Museum of Modern and Contemporary Art, Seoul Museum of Art, and Seoul Art Center's Hangaram Art Museum. A total of 314 questionnaires were analyzed to identify leisure lifestyle factors. On the basis of the lifestyle factors, a cluster analysis was performed, and then the differences of demographics, museum visiting behaviors, and general cultural consumption among the clusters were examined. The cluster analysis revealed four groups of lifestyles, 'culture and art lovers', 'active homebodies', 'low leisure spenders', and 'omnivorous culture and sports participants'. The four groups revealed the differences in terms of demographics, museum visiting behaviors, and general cultural consumption. On the basis of the findings, the marketing strategies targeting the segmented art gallery markets were discussed.

The purpose of this study is to examine whether the national pension affects the life satisfaction of old age, using the first and third-wave data from the Korean Retirement and Income Study. The study analyzes the relationship between the national pension and life satisfaction, using several operational definitions of these two variables. This study utilizes the Difference-in-Difference(2D) models and panel data analysis. The main results are : First, the result of simple 2D shows that there is not significantly difference between the pensioner and that of non-pensioner. Second, the result of 2D regression also shows that pension is not significantly associated with life satisfaction of the old age. Lastly, the result of fixed-effect model confirms that the national pension does not have a statistically meaningful effect on the life satisfaction, controling for the unobserved characteristics of the old age. This study also conducts sensitivity analysis and discusses policy implications.

문자메시지를 작성하는 작업 특성과 사용자의 특성간의 상호작용의 결과로, 휴대전화 사용자 집단간 통화량과 문자메시지 사용량은 다르게 나타난다. 본 연구에서는 문장 입력시간을 기준으로 청년층과 중장년층 집단 간의 운지 속도를 비교하여 노화로 인한 운지 속도의 차이를 고려한 지적활동의 시간 차이를 알아보고자 하였다. 그리고 한글 문자 입력 과제의 수행을 반복하여 청년층과 중장년층의 입력 속도 변화를 비교하였다. 즉, 사용자가 충분한 연습을 거치면 연령층에 관계없이 문장 입력 시간이 비슷해질 수 있는지를 실험을 통해 확인하였다. 휴대전화의 문자 입력 시스템에 익숙하지 않은 청년층과 중장년층 각각 8명을 선발하였으며, 50ms단위로 입력시간을 측정하였다. 실험결과, 두 집단의 연습 이후의 성취한 문장입력 수행도는 유의한 차이가 있는 것으로 나타났다 (P=0.039). 이러한 결과는 노화로 인한 인지적 기능의 저하가 문자 입력의 속도를 저해하는 주요 요인임을 보여준다.

We investigated the relationship of brain dominance with mathematics and science achievement. The participants were 131 middle school students (male: 74, female: 57). It was found that the above average group in mathematics and science achievement had the highest frequency with left lower brain (LLB) (mathematics: 33.8%, science: 35.0%), whereas the below average group in mathematics and science achievement had the highest frequency with right lower brain (RLB) (mathematics: 38.7%, science: 36.1%). The LLB score showed a significant difference between the above average group and the below average group in science (p<.05). In the correlational analysis, the LLB scores had the highest correlation coefficients (mathematics: r=.28, science: r=.26). The LUB scores had the second highest correlation coefficients (mathematics: r=.18, science: r=.24). These results suggest that LLB and LUB are related to mathematics and science achievement. Therefore, we insist that the assessment of mathematics and science achievement should consider brain dominance.

The purpose of this study is to gain knowledge about the influence of running time of 3D stereoscopic video on audience perceptions. This study compares the influence of running time between 20 minutes and 40 minutes of 3D stereoscopic music shows on audience perceptions such as perceived characteristics, impression, presence, entertainment, fatigue and unnatural looking images. After experiment with 40 samples, the present research found that when people watched shorter 3D stereoscopic music video, they perceived more 3D functionality, such as depth, image conveyance and message conveyance. The results also suggest that people who watched shorter 3D stereoscopic video felt more impression such as definiteness and freshness from the 3D images. Moreover, the result confirm that when watching shorter 3D images, people felt more a sense of presence. Findings of this study have important practical implications how running time is important to 3DTV viewers. Since the nature of this study is exploratory, more research about segmented running time and genre, etc. of 3D stereoscopic videos will be needed.

The importance of users on library catalogs cannot be overemphasized. However little is verified about how well the users' needs have been met. The purpose of this research is to explore the characteristics and differences between user groups on library catalogs, and to draw implications for follow-up research. To the end, this research classified the users into four groups: elementary students, middle and high school students, college students, and the general public. Investigated are unique features and differences in searching behavior on library catalogs between the four groups. The data was collected through a survey with 544 users, and analyzed for both frequency test and Chi-square test. The major research results shows that there were statistically meaningful differences between the four groups. Also discussed are several suggestions for more in-depth research.

본 연구의 목적은 일주일간 조사된 개인통행행태를 고려한 각 특성별 통행발생예측 방법을 제시하는데 있다. 이를 위하여 일주일간 통행빈도수의 차이를 고려한 집단간 차이를 검정하고, 그 원인을 분석하여 이에 따른 특성별 개인 통행발생예측 모형을 정립하였다. 전체 표본의 각 특성별 개인 내부 변이성을 분석해 본 결과 기간의 차이에 따른 개인 통행행태의 변화는 직업별, 나이별, 성별, 차량소유 유무, 주택소유 형태, 통행목적, 통행수단, 가구원수에 따라 집단간 차이를 보여주었다. 이러한 변수를 이용한 통행발생 예측모형의 분석결과 개인소득이 높을수록, 주책을 자가로 소유한 경우, 자동차를 소유한 경우, 학생일수록, 유직일수록 개인 통행발생량이 많은 것으로 분석되었다. 반면, 아니는 연령대가 높아질수록 통행수가 적어졌다.
