이 연구의 목적은 초등학교 고학년을 대상으로 학급응집력 향상을 위한 집단상담 프로그램을 구안하고 그 효과를 검증하는데 있다. 이 연구는 박인우(1995)의 체계적인 상담 프로그램 개발 모형을 바탕으로 구성되었으며, 초등학교 고학년의 특성과 학급응집력 관련 선행연구 분석, 초등학교 고학년의 학급응집력에 관한 요구조사 결과를 토대로 설계하였다. 본 연구의 가설 검증을 위해 C지역에 소재하고 있는 B초등학교 5학년 한 학급 22명을 실험집단, 사전응집력검사정도가 가장 유사한 M초등학교 5학년 한 학급 21명을 통제집단으로 선정하여 프로그램을 실시하였다. 검사도구로는 이상희 외(2000)의 학급응집력검사지를 사용하였고 자료 처리는 혼합변량분석(Mixed ANOVA)으로 하였으며 양적 연구의 한계를 보완하기 위하여 집단원의 경험보고서와 상담자의 관찰내용을 분석하였다. 그 결과, 실험집단과 통제집단 간의 학급응집력에 유의한 차이가 있어 본 프로그램이 초등학교 고학년의 학급응집력 향상에 긍정적인 영향을 준 것으로 나타났다. The purpose of this study is to design and apply a group counseling program to improve the class cohesiveness to verify how the program affects the improvement of the class cohesiveness of the higher graders of the elementary school. The program was developed based on the systematic counseling program development model suggested by Inwoo Park (1995,) a review of the existing studies on the class cohesiveness and other characteristics of the higher-graders of elementary schools, and the resultant analysis of a test and survey on the class cohesiveness by the target population. For this study, 22 samples from the 5th year classes in B Elementary School located in J city (the name of the city given in an initial.), Choongbuk, and another 21 students from the 5th year classes of M Elementary School, which had the most similar level of class cohesiveness compared to the first group, were accepted as the test group and the control group, respectively. The tools of the test were the class cohesiveness test questionnaire developed by Sanghee Lee (2000) and the collected data were analyzed using a Mixed ANOVA analysis on SPSS/Windows 18.0 software. In order to compensate for the limitations of a quantitative study, the self-reports of the samples in the groups and the observations by the counselors were used for further analysis. The findings from the study were as follows; firstly, there was a significant difference between the test group and the control group in terms of the class cohesiveness. Secondly, the self-reports from the subjects achieved at each session and the observations by the counselors were analyzed to reach the conclusion that the program in this study had a positive influence on the class cohesiveness of the target population.

As chorion and amnion fusion usually occurs between 14 and 16 weeks of gestation, sonographic identification of chorion and amniotic membrane separation is a normal finding before 14 weeks. However, persistent separation after 16 weeks of gestation is considered rare and abnormal findings. Complete chorioamniotic membrane separation (CMS) may occur spontaneously, but has also been described as a complication of all invasive intrauterine procedures, including amniocentesis. Complete CMS have a significant morbidity and mortality due to intrauterine fetal death, cord complications, and preterm delivery. Aggressive treatment with hospitalization is necessary. We now report 2 cases of complete CMS identified by prenatal ultrasound; 1 in spontaneous complete CMS diagnosed at 24 weeks of gestation, and health premature child was born at 29+3 weeks of gestation, who was alive and well at present; 1 in complete CMS diagnosed at 21 weeks of gestation after amniocentesis, and fetal demise at 24 weeks of gestation due to cord strangulation by an amniotic band. We experienced two cases of complete CMS and report with a brief review of literatures.

Magnetic fluid seal is characterized by its simple design, low friction and being dustless. Those advantages are deduced from the fact that the sealing element is not a solid such as rubber or plastic but it is a fluid. Those are critical for application to a rotating shaft which is inserted into a vacuum chamber where high level of vacuum and cleanness are required. For the reason the magnetic fluid seal has become a standard for vacuum chambers for semiconductor and LCD processing. It should be noted that its sealing performance is sensitive to temperature. If necessary, water cooling should be considered. Thus anticipation of the temperature distribution of the magnetic fluid seal is important before applying it. In this paper an FEM analysis of the heat transfer has been executed and compared with experimental results. An overall convective heat transfer coefficient has been adopted for the analysis, which results in satisfactory consistency of the theoretical and experimental results.
