The purpose of this research was to examine the quality features of experimental case studies in early childhood special education in Korea through contents and methodology analysis. For this, 35 experimental case studies that were published from 1998 to 2004 in eight journals were reviewed. Studies were analysed according to participants' characteristics and settings, and contexts of methodology and quality features. The effectiveness of practices was examined according to the criterion of the American Psychological Association. The quality features of study that were assessed included research designs, fidelity of intervention, maintenance, generalization of effect, and social validity.The results of this study were as follows: first, the primary participants were children with developmental delays and language disorders, and the research was mostly conducted in clinical or segregated settings such as theraputic rooms and special classrooms. The descriptions of subjects and settings were insufficient. Second, the research studies primarily employed multiple baseline experimental designs, though AB design was also popular. Third, the analysis of quality features found insufficient fidelity of intervention procedures and evidence of generalization effect and social validity, and relative sufficiency with regard to the evidence of effectiveness and maintenance. Fourth, practices with well-established evidence of effectiveness were play activities structured and response prompting. Probably efficacious practices included functional assessment and positive behavior support, reinforcement, linguistic and acoustic approaches, naturalistic teaching approaches, family participation, and assistive technology.It is suggested that researchers should provide detailed descriptions of participants and settings, use a variety of research designs, measure independent variables and fidelity of intervention, evidence of intervention generalization, and social validity. We need more researchers in Korea, who are interested in investigating current practices or intervention strategies that are recommended in early childhood special education. It is necessary to introduce new practices to the field, which have well-established evidence of effectiveness. We also need research in inclusive settings to support young children with disabilities and provide comprehensive services to them.

The purpose of this study was to investigate the ways which educational evaluation was implemented in early childhood special education programs. Six teachers from early childhood special education programs were interviewed and relevant documents were collected. The findings of this study were as below: First, as for the purpose and content of evaluation, the teachers who participated were found to only be aware that educational evaluation was geared toward collecting information about children and choosing appropriate educational programs. Few considered it necessary to assess family services or the educational program itself. Second, it was found that an accurate and workable evaluation plan is required to be established in the beginning of every year to increase its adequacy and efficiency. Third, it was found that the type and frequency of evaluation differed. There were no specific criteria for evaluations, and they were fulfilled only in some fixed ways. The evaluation methods and instruments should be diversified and suitable for young children. Fourth, regarding evaluation procedure and feedback, it was found that the teachers rarely consulted with other professionals or parents, even when they saw a need to do so. Fifth, it was found that the number of teaching personnel should be increased to reduce the teacher to child ratios to ensure more successful individualized education and evaluation.

본 연구는 야영장의 선호요인과 이용 만족도를 분석하여 이용객의 만족도에 영향을 주는 요인을 조사하여 야영장의 설치 및 운영에 필요한 자료를 제공한다. 연구 결과를 요약하면 다음과 같다. 1. 야영장의 이용은 남성이 여성에 비하여 이용 빈도가 높게 나타났다. 야영장의 주된 이용 연령은 30대가 가장 높으며 휴식을 목적으로 야영장을 이용한다. 이용 집단의 규모는 $2{\sim}4$명이 가장 높게 나타났다. 2. 시설 만족도에 관한 13가지 항목에 대한 요인분석 결과, 시설 요인, 심리 요인, 주변 환경 요인, 접근 요인으로 분류할 수 있다. 3. 시설 요인에서는 화장실에 대한 만족도, 심리 요인에서는 재방문 의사에 대한 만족도, 주변환경 요인에 대한 항목에서는 경관적 요소, 접근성 요인에 대한 항목에서는 안내 표식체계에 대한 항목이 높은 영향력이 있다. 4. 전체 만족도에 영향을 주는 요인은 시설 요인, 심리 요인, 접근 요인, 주변환경 요인 순으로 영향을 주는 것으로 나타났다.

We analyzed wind speed over South Korea for HALE UAV(High Altitude Long Endurance Unmaned Aerial Vehicle) flight safety. Annual variation of wind speed at 200 hPa showed that winter season was stronger than summer. According to latitude, wind speeds in January and August were found to be $52{\sim}74m\;s^{-1}$ and $15{\sim}26m\;s^{-1}$, respectively. Wind speed was stronger(weaker) at lower latitudes than higher latitudes in winter(summer). Frequency(%) of wind speed less than threshold value($18m\;s^{-1}$) for the operation date was investigated. The days showing the frequency greater than 60 % in all altitudes of surface ~ 50 hPa showed the range of 1 ~ 33 days at 7 stations. Operation date was the longest period at Gosan. The appropriate date of HALE UAV operation at Gosan and Osan is considered as the middle of July ~ middle of August and end of July ~ early August, respectively. These results can be used to determine the operation date of HALE UAV.
