The purpose of this study was to identify the characteristics of the culture of parents participating in schooling of special school. For this purpose, this study dealt with 5 key areas relating to culture of parents: 1) the educational view of parents(or the educational goal), 2) roles and limits of parents in their participation in schooling, 3) ways and types, 4) range, and 5) cooperation and conflict in their participation in schooling. Data were collected through participant observation and depth interview with parents of the middle class students attended A special school. Based on data collected in this study, the characteristics of parents` culture in schooling were defined as follows. First, parents tended to emphasize their offspring`s self-help ability for daily life as a ultimate educational value and goal because he or she had severe disability. They hoped that their offspring have basic self-help abilities for daily life when they can`t take care of him any longer. Therefore, because they thought of such educational goal as Maginot Line, they taken an active part in schooling and thought of it as a mean to affect schooling policies and to derive it`s positive change. Second, parents thought of participating in school events and activities as their roles in schooling, but they also wanted to see their offspring`s school life as it is. Factors facilitating parents` participation in schooling were as follows: a wish to see their offspring`s adaptive change and get a feeling of relief, the apprehension that their offspring may not adjust due to his disability, and disadvantages to be when they don`t participate in schooling and advantages when they do. These factors indicate parents` earnest wish for their offspring`s adjustment and strong demand for school authorities` concerns with their offspring. Factors hindering from parents` participation in schooling were a long distance to school from home and a lack of time. Third, parents primarily had participated in schooling through bonding among parents. Actually they have a meeting more than once a month along class, grade, or the degree of disability. At the meeting, they have shared a lot of information relating to the day-to-day happenings in school and their own difficulties or experiences. Such bonding among parents have played a critical role in communicating with teachers and school authority. Parents have created tight culture based on trust for each other. Fourth, parents thought that they need to had the authority to evaluate and appoint part-time instructors taken on after school and weekend programs, which is ran by parents` bill. Also parents thought that they need to had the right to receive feedback about their demands from school authority. Of course, parents thought that they shouldn`t invade teacher`s specialty. These demands basically seem to imply the need for feedback about practice of teaching made in school. Finally, as parents` participation in schooling had increased in both quantitative and qualitative aspect, there ware cooperation and conflict between parents and school. Parents actively participated in school events and activities, but rapped out a complaint directly with school, especially when they thought that their offspring have a disadvantage from school. Behind such rapping out it, there was parents` complicated mind, such as feeling of guilt and responsibility for their offspring with disability and anxiety that this disadvantage will recur, if not rap out it.

When the exposed surface of rock slopes investigated, various factors have not been considered. The factors required to be considered include the vlume swelling of rock caused by stress release at the fault zone, unexposed discontinuities in the earth and so on. Also, rock slope failure occurs sometimes due to these factors. In this paper, we intend to help engineers to judge about the stability of similar new cutting-slopes or the maintenance of already cut-slope, so that they can consider these factors. 암반사면에 대한 표면조사 시에는, 암반 사면파괴로 인한 재해의 원인이 될 수 있는 파쇄대에서의 응력이완, 노출되지 않은 불연속면 등의 요인들을 고려하지 못하는 한계가 있다. 이에 본 고에서는 사면의 절취 또는 절취사면의 유지관리에 있어서 사면 안정성에 대한 판단을 도와 사연 파괴로 인한 재해를 예방하는 방안을 제시하고자 한다.

It is well known that stiffness of composites depends on layup sequence of CFRP(carbon fiber reinforced plastics) laminates because the layup of composite laminates influences their properties. Ultrasonic NDE of composite laminates is often based on the backwall echoes of the sample. A pair of such transducers was mounted in a holder in a nose-to-nose fashion to be used as a scanning probe on composites. Miniature potted angle beam transducers were used ( Rayleigh waves in steel) on solid laminates of composites. Experiments were performed to understand the behavior of the transducers and the nature of the waves generated in the composite (mode, wave speed, angle of refraction). C-scan images of flaws and impact damage were then produced by combining the pitch-catch probe with a portable manual scanner known as the Generic Scanner (”GenScan”). The pitch-catch signal was found to be more sensitive than normal incidence backwall echo of longitudinal wave to fiber orientation of the CFRP composites, including low level porosity, ply waviness, and cracks. Therefore, it is found that the experimentally Rayleigh wave variation of pitch-catch ultrasonic signal was consistent with numerical results and one-side ultrasonic measurement might be very useful to detect the defects.

Objectives:Considering the significant limitations of current available interventions on attention-deficit/hyperactivity disorder(ADHD), it has become a consensus among clinicians that new treatment options for ADHD are needed. In recent years, Neurofeedback(NF) has been suggested as a promising possibility. This article aims to review studies that have existing evidence and to inform clinicians on the use of NF as an alternative treatment for ADHD. Methods:Website Pubmed was searched in order to get studies that NF used for treatment of ADHD. We had select studies designed randomized controlled trials, peer reviewed. Results:10 studies and 1 consult study reviewed. There are no positive results except 2 studies reported statistically significant improvement of neurocognitive function. All other studies either did not directly test or did not demonstrate significant differences between θ/β training compared to wait list control, placebo control, or active treatment control. The findings of the studies reviewed do not support NF training as a first-line therapy. Conclusion:ADHD patients have treated with NF in many studies reported results statistically not significant improvement of neurocognitive function. But It’s therapeutic value can not be entirely refuse compared to different empirical treatments. In future, more research is needed on issues such as diversified NF according to ADHD subtypes, patient characteristics, and other non-specific treatment effects.
