Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

The research investigates the effect of extracurricular activities to self - esteem and is classified into three factors:- physical factors, artistic factors, and intellectual factors. They were analized by the effects of self-physical and self-esteem The children who have extracurricular activities more than 2 times a week (each at least 50 mins after school). Children living in Southern part of Gwang-ju city( Nam Gwang-ju), were targeted for the study. We used a self-physical survey report and a self-esteem survey report as the method of research. However, we excluded some insincere survey datas such as double entrys or blank entrys, only secure data was included and analized by SPSS 10.0. We reach some conclusions from the collected datas used by a standard variance, a analysis of reliability, multiful response cross-tab, one-way anova, correlation, followed as below ; 1. The school childrens extracurricular activities on participation characteristics shows that depending on sex, family income, the intellectual activities, artistic activities, physical activities follow the academic level of the children in school. Also it shows that the physical activities of school children decrease as the increase in grade. 2. The psychological characteristics follow the dynamic statistic of population and the academic year, it shows the small contrast that is : first, the self-esteem depends on the family income and the academic year. second, the self-effect depends on sex, family income and the academic year. third, the self-physical depends on family income and the academic year. fourth, the self-achievement depends on family income, parents academic background (especially mother's )and the academic year. 3. The psychological characteristics follows the form of activities after school. It shows the small contrast in self-effect and self-physical. 4. We found that there is a high mutual relationship between the psychological characteristic factors. The self-esteem was getting higher as the childeren improved in self-physical and self-effect, through the extracurricular activities after school.

Tooth bleaching has been prevailing recently for its ability to recover the color and shape of natural teeth without reduction of tooth material. However, it has been reported that bleaching procedure adversely affects the adhesive bond strength of composite resin to tooth. At the same time the bond strength was reported to be regained by application of some chemical agents. The purpose of this in vitro study was to investigate the effect of the removal of residual peroxide on the composite- enamel adhesion and also evaluated fracture mode between resin and enamel after bleaching. Sixty extracted human anterior and premolar teeth were divided into 5 groups and bleached by combined technique using office bleaching with 35 % hydrogen peroxide and matrix bleaching with 10% carbamide peroxide for 4 weeks. After bleaching, the labial surfaces of each tooth were treated with catalase, 70% ethyl alcohol, distilled water and filled with composite resin. Shear bond strength was tested and the fractured surfaces were also examined with SEM. Analysis revealed significantly higher bond strength values. (p<0.05) for catalase-treated specimens, but water-treated specimens showed reduction of bond strength, alcohol- treated specimens had medium value between the two groups(p<0.05). The fracture mode was shown that the catalase group and the alchohol group had cohesive failure but the water sprayed group had adhesive failure. It was concluded that the per-oxide residues in tooth after bleaching seems to be removed by gradual diffusion and the free radical oxygen from peroxide prevents polymerization by combining catalyst in the resin monomer. Therefore it may be possible to eliminate the adverse effect on the adhesion of composite resin to enamel after bleaching by using water displacement solution or dentin bonding agent including it for effective removal of residual per-oxide Key words : Vital tooth bleaching, Shear bond strength, Composite resin, Fracture mode catalase, Ethylalcohol, Free oxygen radical, Adhesive failure, Cohesive failure

The purpose of this study was to analyze the professionalism of elementary school teachers and to draw out factors which elementary teachers should try to improve their professionalism for environmental education. For the study, both Quantitative analysis and qualitative methodologies were applied: First, randomly selected 483 elementary teachers from Seoul and Gyeonggi self responded to 5 evaluation areas by Hungerford et al. (1994) to evaluate their environmental education professionalism through the use of five point Likert scale. Second, 2 elementary teachers' environmental classes were observed for the purpose of analyzing strengths and weaknesses in classroom instruction, and then the results of self-evaluation on environmental education professionalism and teacher professionalism as shown in the classes were compared. It was found that 483 elementary teachers including 2 teachers for analyzing classroom instruction who performed a self-evaluation gave themselves mid-scores on the Hungerford et al.'s 5 evaluation areas. However, the result of self-evaluation did not correspond with the result of actual class observation and teacher interview. That is, the actual environmental classes conducted by 2 teachers did not seemed to reflect the evaluation areas which were the foundation of the study: the conceptual awareness, the investigation & evaluation, environmental action skills, and educational application. The results of this study can be used as the basis reference to develop teaching-learning program and in-service programs for professional development of teachers for successful application of environmental education in elementary school classes.

장애인의 기능을 향상시킬 수 있는 방법 중 하나는 보조공학기기의 제공이다. 보조공학기기의 제공은 감각, 지각, 인지, 운동능력 등을 전문적으로 평가할 수 있는 전문가에 의해 선택, 적용, 훈련되는 것이 중요하다. 또한 근골격계 질환을 예방하기 위한 인간공학적 접근에 대한 이해와 작업분석, 직무조정이 가능한 전문가에 의해 보조공학기기가 제공된다면 잔존기능의 향상 뿐 아니라 업무동안 바람직하지 못한 자세를 유지함으로써 발병할 수 있는 근골격계 질환 예방까지 기대할 수 있을 것이다. 본 연구에서는 보조공학기기의 이론적 배경과 인간공학적 접근의 이론적 배경을 소개하였고, 적절한 보조도구를 제공한 장애 근로자에 대해 근골격계 질환 위험요인을 측정하였으며, 이를 통한 자세보완이 장애 근로자의 작업 기능을 향상시킬 수 있음을 객관적으로 밝히는 평가결과를 제시하였다. 따라서 장애인의 직업능력을 향상시키려면 다양한 전문가들의 팀 어프로치가 필요하며 체계적인 서비스가 마련되어야 할 것이다. One of the methods to improve functions of the disabled person is to supply assistive devices. It is important for the disabled person that the devices should be supplied by an expert, who is capable of evaluating their sensory, perception, cognition and motor function. Moreover if the expert have knowledge about ergonomlcs, he or she will also prevent the musculo-skeletal disease which may be happen in work place. In this paper, we introduced the theoretical background of the assistive devices and ergonomic approach, and evaluate the risk factors of the musculo-skeletal disease of the disabled worker who was equipped a proper assistive device, and presented objective experimental results that posture intervention by using assistive device can be useful to improve work function of the disabled worker.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

On the Critical Behavior of Phase Changes of a Forward-Scattered Light in a Nonpolar Binary Liquid Mixture

The effect of concentration fluctuations on the changes of azimuth and ellipticity are analytically obtained in a binary chiral liquid mixture, when the incident light is completely linearly polarized above (or below) the horizontal at 45°. The important results are as follows;(1) When the binary liquid is in the critical region far from the cr5itical point, the ellipticity change is proportional to isothermal compressibility factor and the fifth order of frequency and shows the logarithmic divergence. (2) In the case that the system is in the critical region far from the critical point, the azimuth change is solely due to the molecular contribution. As the system approaches to the critical point, the effect of fluctuations becomes important. If it is in the extreme close to the critical point, the term due to the concentration fluctuations is comparable to or larger than the molecular contribution.
