This paper investigated the effects of dynamic postural control for maintaining upright standing on a support surface during continuous sinusoidal horizontal translation in anterior-posterior direction. 15 healthy young subjects participated in this experiment. The analysis of body movement was analyzed using Ariel Performance Analysis System. Motion pattern was analyzed by seven markers on subject's body. Position of markers were head, chest, hip, right knee, left knee, right ankle and left ankle. Seven different frequencies of support surface were employed ; 0.1, 0.25, 0.5, 0.75, 1, 1.5 and 2Hz at 2cm of moving path of motionbase. The experiments were performed dynamic postural reponses at the condition of eye open. The results showed that median frequency of the knee, ankle were increased in all frequency bands. Following the frequency of perturbation increased, postural control strategy was changed from ankle strategy to combined strategy. The experiment results could be applied to the dynamic postural training for the elderly and the rehabilitation training for the patients to improving the ability of postural control.

This paper investigated the effects of dynamic postural response for maintaining upright standing on a support surface during horizontal vibration in anterior-posterior and medial-lateral direction. Seven healthy young subjects participated in this study. Postural control was analyzed by the measurement of COP (center of pressure) sway. Three different frequencies and two different amplitudes of support surface were employed: O.6Hz, 102Hz, 1.8Hz and 204Hz at 1cm, 3cm. The experiments were performed dynamic postural reponses at the condition of eye open and close. The electrornyographic signals of the four muscles in lower extremities were recorded and analyzed in the frequency domain: the muscles of interest were rectus femoris (RF), biceps femoris (BF), gastrocnemius (Ga), tibialis anterior (T A). The experimental results showed the difference of muscular activities at the different frequencies, amplitudes and the vibration directions of the support surface. For the anterior-posterior and medial-lateral direction, the Ga showed highest activities. Also, the rate of the increase in the muscular activities was affected by the frequency and amplitude. This paper could be applied to the dynamic postural training for the elderly and the rehabilitation training for the patients to improving the ability of postural control.

Nowadays, juvenile's sexual-related delinquency is increasing and their immature sexual behavior is on issue with this recent phenomenon. That is the reason people realize offering right sex education for them is important. So, we are going to study for trying to make an improvement in sex education field based on the fact that is practicing now at school. We will reference "소중한 성 바로알기" in this study which is published in 2008 for schoolteacher to compensate some limitations of former education material. This study was done from June 15 to July 20, 2009(Total : 36days) and aimed for surveying senior year students of middle school located in Seoul, S. Korea. We sampled 248 students by random from 8 classes of 4 schools. We analyzed final 209 samples(the other 39 samples were omitted for inappropriate response and return.) using SPSS WIN 12.0. The questionnaire includes 4 parts of relationship and psychosexual, physical growth and sexual health, social environment and sexual equality, and healthy family with marriage and it consists of 31 questions. We made this questionnaire base on the reference as we stated above. From this study we found the part of healthy family with marriage has not enough contents compared with the other 3 parts. And also we could see students don't feel satisfaction with one-off, one-sided sex education, and the education which is performed with only one single method. Therefore we make a judgement that middle school students have their needs toward sex education at school and those are considered as regular education by well-trained education provider, and various means for education such as case study, discussion, or role play. As well we think sex education for middle school students need to offer more about sexual equality and also alert the increasing possibilities of sexual commit in cyber space to adolescent.
