This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

임상에서 점차 Mineral Trioxide Aggregate (MTA) 에 대한 우수성이 소개되면서, apical matrix로의 사용은 주목할 만하다 할 수 있다. 본 연구의 목적은 개방형근관에서 MTA가 apical matrix로 사용될 때의 치근단 밀폐효과를 알아보고, 근관충전의 시기와 matrix의 두께가 치근단 밀폐에 미치는 영향을 치근단 미세누출의 측면과 matrix탈락빈도의 측면에서 관찰하고자 하는 것이다. 개방형 근관을 재현하고자 45개의 발거된 단근치에 #90크기로 근단공을 형성하였고, 투명레진등을 이용하여 치근단병소를 갖는 치조골을 재현한 후, 4개의 실험 군과 1개의 대조 군으로 분류하였다. A군: 2mm두께의 MTA matrix 형성후, 열연화된 Gutta-percha와AH26 sealer를 이용하여 즉시 근관충전. B군: 2mm두께의 MTA matrix 형성후, A군과 같은 방법으로 24시간 후 근관충전. C군: 4mm 두께의 MTA matrix 형성후, A군과 같은 방법으로 즉시 근관충전. D군: 4mm두께의 MTA matrix 형성후, A군과 같은 방법으로 24시간 후 근관충전. 대조군: matrix를 사용하지 않고 열연화된 Gutta-percha와 AH26 sealer를 이용하여 근관충전하였다. Matrix의 탈락이 있는 경우 기록하고 완전수세 후 다시 시행하였다. 색소침투정도의 평가를 위해 methylene blue 에 치아를 48시간 침수시킨 후 협설로 양분하였다. 각 시편들을 고배율 현미경 관찰 후 비디오촬영 하였고, digitalized image analysing program 을 이용하여 두명의 관찰자가 누출의 정도를 평가한 후, One-way ANOVA로 통계적 유의성을 검증하여 다음과 같은 결과를 얻었다. 1. Matrix를 사용한 실험 군이 matrix를 사용하지 않은 대조 군에 비해 유의성 있게 낮은 누출을 보였다(p<0.05) . 그러나 근관충전시기와 matrix의 두께를 달리한 실험군 내에서는 누출에 유의성 있는 차이가 나타나지 않았다. 2 모든 실험군에서 gutta-percha를 이용한 근관충전의 시기에 matrix탈락 및 gutta-percha 의 압출은 발생하지 않았다.

발달장애학생을 위한 웹기반 의사소통능력신장 프로그램의 개발과 적용 사례

김동현,유영환,김좌중,천경철,이청용,김봉수 국립특수교육원 2005 연구보고서 Vol.- No.10

발달장애학생의 의사소통능력은 단순한 언어문제 이상의 의미를 지닌다. 의사소통능력은 모든 학습의 기초가 되고 결국 인간의 삶의 질을 좌우하게 하는 중요한 요소가 되고 있기 때문에 의사소통능력에 문제가 많은 발달장애학생에게 있어서 의사소통능력 신장은 매우 중요하다. 발달장애학생의 언어 및 의사소통능력의 결함은 사회적 결함과 인지적 결함에 상호 관련성이 있어 다른 사람으로부터의 의사소통을 이해하는 능력과 자신의 생각을 표현하는 능력이 제한되어 다른 사람과의 상호관계를 맺는데 어려움이 많았다. 따라서 발달장애학생의 언어지도는 생활 장면에서 교수하는 것이 가장 바람직하다고 하겠다. 그러나 지금까지 주로 활용된 전통적인 언어지도 방법은 어휘를 증가시키고, 발화의 길이를 널리는 데는 효과가 있었지만, 학습된 내용을 생활 장면에서의 일반화에는 문제점이 있는 것으로 지적되고 있다. 발달장애학생의 언어지도 방법은 일상생활 속에서 학습 내용을 선정하고 이를 실생활 장면 혹은 이와 유사한 환경에서 효과적으로 지도할 수 있는 적절한 교수 방법이 필요하다. 그래서 발달장애학생의 의사소통능력 신장을 위한 환경중심 언어지도 방법을 활용한 웹(Web)기반 언어지도 프로그램을 개발하였다. 웹(Web)기반 언어지도 프로그램은 제7차 특수학교 기본교육과정과 국립특수교육원에서 발간한 ‘발달장애학생의 언어교육 프로그램(1998)’ 분석을 통하여 개인 · 가정생활, 학교 · 사회생활, 경제 · 여가생활 등의 6개 영역으로 구분하여 각 영역별 학습주제를 선정하였으며, 학습주제에 대한 학습의 진행 형태는 학습목표, 낱말학습, 상황학습, 평가로 진행할 수 있도록 하였으나, 학습자의 현재 수행 능력을 고려하여 능력에 따른 진행의 절차를 학습자가 선택할 수 있게 하였다. 본 프로그램을 적용해본 결과 다음과 같은 교육적인 효과를 얻을 수 있었다. 첫째, 웹을 활용한 가상체험을 통하여 적극적이고 흥미 있는 참여를 유도하며, 학습자 중심의 주도적인 학습과 안내자, 촉진자로서의 교사의 역할을 통해 발달장애학생의 의사소통 능력을 신장시킬 수 있었다. 둘째, 교실에서 이루어지는 지금까지의 수업방식을 탈피하여 학습자가 언제, 어디서나, 누구든지 학습할 수 있는 열린 학습체제의 교육환경을 조성할 수 있었다. 셋째, 문자정보, 그래픽, 애니메이션, 사진, 음성, 비디오 등 다양한 형태의 정보가 상호대화 형식으로 활용되며, 수준별 반복학습을 실시함으로써 교수-학습 방법의 개선뿐만 아니라 양질의 수업을 진행하는데 도움을 줄 수 있었다. 본 프로그램을 활용한 언어지도가 발달장애학생의 의사소통능력 신장을 위한 최선의 방법이라고 말할 수는 없으며, 언어지도의 한 가지 방법이라고 말할 수 있다. 따라서 본 프로그램의 활용한 언어지도는 학교에서 교사가 학생의 능력과 흥미를 고려하여 지도한다면 발달장애 학생의 의사소통능력 신장에 많은 도움이 될 것이다. The developmental disability of the metal handicapped children means more than simple linguistic problem. The developmental disability is the base of all the learning and important factor which decides the happiness of the human being finally, so the extension of mutual understanding ability is so important, in the case of the metal handicapped children who have a problem of the mutual understanding ability. In the case of the metal handicapped children, the defects of the mutual understanding and linguistic ability are related with the social defect and the defect of recognition, and the ability of understanding about mutual relations with other people and self-expression ability are limited. So they have many problems in mutual relations with other people. Therefore, the linguistic instruction of the metal handicapped children is recommended to be done in the living. But, the traditional linguistic instruction which's used mainly as yet, is effective in increase of a vocabulary and the length of a locutionary act, but it has a problem in the popularization of the learning in the real life. The method of the linguistic instruction for the metal handicapped children, should be selected as contents in the real life, and the right learning method which can be done under the real life or the similar environment with it, is needed. Because of the above realities, the linguistic teaching web-based program is developed, using the linguistic instruction which is focused on the environment, for the extension of the mutual understanding ability of the metal handicapped children. In the linguistic teaching web-based program, it is divided with 6 field (personal · home life, school · social life, economical · leisure life) and the educational subject classified by each field is selected, by the analysis of 'The linguistic educational program for the children who have developmental disability' published by the 7th basic education course of special school and the national special education organization. Besides, the progress form of learning about the educational subject is directed by educational goal, word learning, situation learning and valuation, but a learner can choose a procedure followed by ability, regarding to his accomplishment ability. As the result of the application of this program, the educational effects that we could get are the following : 1. We could lead a positive and interesting participation by virtual experience through WEB, and the communication ability of the metal handicapped children was extended by a role of a teacher, as a guide and promoter and a leading learning focused on a learner. 2. The teaching method which is done in school now, is dismissed and we could form the educational environment of the learning system that a learner could learn, without distinction of time, a place and a person. 3. The various form of information, like text, graphic, animation, photo, sound, video and so on, is applied as a form of communication. Therefore, the program was useful in not only the improvement of the teaching-learning method, but also the proceeding of the effective lesson. The linguistic teaching which use this program, can not be the best method of the extension of the mutual understanding ability and it's just one method of linguistic teaching. if the linguistic teaching which use this program is conducted, regarding to a ability and a interest of a student, it will be so useful in the extension of the mutual understanding ability, for the children who have developmental disability.

The effect of polyethylene film(PE) packaging of golden mushroom wrapped with Korean paper containing 20% mica powder on the changes in weight, color, texture, PPO activity, number of total microbe(TM) and sensory quality during storage at 10℃ were investigated. The experiments were divided to 3 groups(control; only PE packaging, KP; PE packaging wrapped with Korean paper up and down of the sample, KPM; PE packaging with Korean paper containing 20% mica powder up and down of the sample). The weight of the mushroom in the KPM was the lowest until 9 days-storage, but the weight was the highest at 15 days-storage, showing 12.5% higher against the initial weight. L^(*) values of the mushrooms in the control and KP treatment were decreased, but the value in the KPM treatment was maintained as the same of the initial value during storage. The increasing rate of a^(*) and b^(*) values in the all plots during storage was the lowest in KPM and in order of KPM<KP<control. The activity of PPO and number of TM in the KPM treatment were maintained the lowest, but hardness and gumminess were maintained the highest during storage. Appearance of the mushroom stored for 15 days was the best, the degree of browning and softening were the lowest in the KPM. Off-flavor was lower in all plots, but the scores were the lowest in KPM. But further study on the fruit body was grown in the KPM at after-period of storage was required.

안동규,변경원,유영태 한국공작기계학회 2007 한국공작기계학회 추계학술대회논문집 Vol.2007 No.-

The objective of this research work is to investigate the influence of process parameters on the surface roughness and the formation of the cut section for the case of cutting of Inconel 718 sheet using high power CW Nd:YAG laser. In order to find the relationship between process parameters and surface roughness, Several linear cutting experiments have been carried out using 6-axis controlled robot laser cutting system. From the results of the experiments, the relationship between process parameters and surface roughness has been obtained. In addition, it has been shown that the surface roughness is highly related to the striation formation of the cut section. The results of experiments have been shown that the surface roughness of the cut section lies in the ranges of Ra of 1.39-5.70㎛ and R_(max), of 8.20-29.10㎛. Through the observation of the cut section, it has been shown that the cut area of the cut section has several oxidized substances and the ductile fracture occurs in the break area.
