Background: To determine effects of mobilization with movements (MWM) application on stroke patient with hypomobility on sacroiliac joint. Methods: The subject was 47years old male who have left hemiplegia because of right intra-cerebral hemorrhage. The subject was have hypomobility on sacroiliac joint. MWM using during 4weeks and using Berg balance scale (BBS), Timed up and go (TUG), 10meter walking (10MW) test for evaluation. Results: The results of this study were summarized below; BBS score for evaluating balance ability was increased, and TUG time, 10MW test time was decrease. Conclusion: We consider that MWM application on stroke patient with hypomobility on sacroiliac joint is not only regain mobility on sacroiliac joint but also increase in balance ability and walking speed.

Subjects with 0.7[clo]'s amount of clothing were estimated on their thermal comfort, concentrativeness, heart rate variability, stress and fatigue degree when given variation in relative humidity to 30, 40, 50, 60, 70, and 80[RH%], in an environmental test room of temperature 25[$^{\circ}C$], illumination 1000[lux] and air velocity 0.02[m/sec], by using EEG, learning ability and HRV. At the result, it was at 50~60[RH%] of relative humidity that subject's thermal comfort and concentrativeness were at the highest while stress were at the lowest, and it was at 60[RH%] of relative humidity that heart rate variability was most stabilized. It was found that when temperature and humidity of the environmental test room are at 25[$^{\circ}C$] and 50~60[RH%], subject's productivity and psychological state are least affected.

This paper describes a method of human sensibility evaluation for pleasant and unpleasant environments. Conditions of the environment are room temperature and humidity. Changing the conditions, 10-channel EEG signals for 4 subjects are collected. Linear predictor coefficients of the recorded EEGs are extracted as the feature parameter of human sensibility. A neural network-based human sensibility estimation algorithm is developed. The developed algorithm showed good performance in the pleasantness evaluation. The neural network output produced accurate states of pleasantness sensibility. Subject-independent test showed similar results with subject-dependent test.

The purpose of this study is to analyze the planning dimensions according to homemaker's age and education. In this study the dimensions of planning are participation, time span , significance, specifity and flexibly. The subject areas of planning are family economy, household activities, child rearing and purchasing. Questionnaires were given to the selected 181 homemakers living in Seoul and Incheon. Data were analyzed by frequency, percent, x2 -test, F-test. The result are as follows: 1) There are significant differences in planning dimensions according to homemaker's age and education in some subject areas. 2)The younger the homemaker is and the higher her educational level is, the more cooperatively the couple plan in family life. 3)The family of which homemaker is younger and more educational tends to plan significantly, specifically and flexibly in family life.

In this study we developed monosyllable lists for articulation test for Korean. We sampled 103,581 colloquial monosyllables, applied them to five selection rules that based on Korean linguistic characteristics, and finally constructed five different lists with fifty monosyllables. The validity test using the monaural impairment factors such as S/N ratio and cut-off frequency showed that articulation scores were chanted systematically according to the level of impairment factors. In addition, we investigated the effect of azimuth of a single competing sound upon articulation scores. The syllables were always reproduced by the loudspeaker in front of the subject, while Hoth noise were reproduced by the loudspeaker with varying azimuth around subject. The result indicated that the articulation depended on the azimuth of competing sound sources. Finally, no significant differences among lists were found in all experimental conditions.

Magnetic Levitated(Maglev) Vehicle, which utilizes electromagnetic forces between dual-pole electromagnets and a steel rail, generally runs on guideway structures. A prototype of an Urban Maglev Vehicle has been developed and tested in Korea, This study was conducted as a cooperation research subject of the 3-1 subject, performance improvement of maglev track structures, of the Center for Urban Maglev Program, statred in 2006. As the Maglev load is distributed rather than concentrated, a field test was conducted on Simple Span PSC-BOX Girder Bridge(L=25.0m) of the Expo-Maglev test track in Daejeon to examine the dynamic effect of the Maglev load on the bridge. Numerical analyses were also performed up to the maximum passing speed of 110 km/h by 10 km/h increments of Maglev Vehicle using Finite Element model of bridge, and girder deflections, accelerations and Dynamic Amplification Factor (DAF) are analysed.

Background: The objective of this study was to determine whether sensorimotor training using an unstable surface affects dynamic balance and gait function in patients with hemiparesis, and to compare the effect of sensorimotor training with that of cycling exercise. Methods: Two subjects with post-stroke hemiparesis volunteered to participate in this study. Single-subject A-B design with alternating treatment was used for this study. Baseline(A) and intervention(B) phases were performed for 7 and 8 sessions, respectively. Sensorimotor training and cycling exercise were performed for 20 minutes in randomized order. Assessment tools were made by using a step test, timed up and go(TUG) test, and 6-minute walk test(6MWT). Results: Each of the participants improved in all three tests after the two interventions. Participants 1 and 2 showed the improvement for their assessment score after sensorimotor training in the step test by 42.1%(p<.05) and 58%, in the TUG, 31% and 19.5%, and in the 6MWT test, 32.3% and 10.6%(p<.05), respectively. After cycling exercise, participants 1 and 2 also improved in the step test by 32.5% and 53.1%, in the TUG, 27.4% and 18%, and in the 6MWT test, 28.8% and 3%. In statistical analysis between the two interventions, sensorimotor training showed a significant increased values in the step test for participant 1 and the 6MWT for participant 2 as compared with those of cycling exercise. Conclusion: Sensorimotor training and cycling exercise are helpful for improving dynamic balance and gait capacity. Furthermore, sensorimotor training may be more helpful than cycling exercise.
