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.

쿠싱증후군 환자에서 당 대사 이상 정도에 따른 인슐린 감수성과 인슐린 저항성의 변화

정인경,김성훈,정재훈,민용기,이명식,이문규,유형준,안규정,노정현,김동준,김광원 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.4

연구배경 당질 코르티코이드는 당 대사에 매우 중요한 호르몬으로 내인성 당질 코르티코이드 과다상태인 쿠싱증후군에서는 말초조직에서 인슐린 저항이 증가하고 이를 보상하고자 인슐린 분비의 증가로 고인슐린혈증이 동반된다고 보고되고 있다. 하지만 생체 내에서와 달리 시험관내에서는 췌도세포에 당질 코르티코이드를 장시간 처리하면, 인슐린 분비 및 생합성이직접적으로 억제됨이 확인된 바 있어 쿠싱증후군 환자에서 당뇨병의 원인으로는 아마도 말초조직에서 증가된 인슐린 저항성 뿐 아니라 이를 충분히 보상하지 못하는 췌장에서의 인슐린 분비 저하가 같이 동반되어있지 않을까 하는 가설을 세우게 되었고, 아직까지 당질코르티코이드가 당대사 이상을 일으키는 기전에 대해 쿠싱증후군을 당대사 정도에 따라 인슐린 감수성과 분비능을 분석한 연구는 없었기에 이를 알아보고자 하였다. 방법: 삼성서울병원에서 쿠싱증후군으로 진단 받은 환자 15명을 대상으로 하였다. 이에 대한 대조군으로는 쿠싱증후군 환자와 같은 성별 그리고 체질량지수를 갖은 15명의 건강한 성인을 대상으로 비교 하였다 쿠싱증후군 환자를 대상으로 경구당부하 검사를 통해 당대사 정도를 정상군, 내당능장애군, 그리고 당뇨병군으로 나눈 후 정맥 당부하 검사를 시행하여 각군의 인슐린 저항성과 인슐린 분비능의 지표를 비교하고, 수술 후 쿠싱증후군이 완치된 상태에서 수술 전후의 당대사 지표의 변화를 조사하였다. 결과: 1) 쿠싱증후군 환자 중 정상인은 20%, 내당능 장애는 27%, 그리고 당뇨병은 53%였다. 체질량지수, 나이, 그리고 발병 기간은 세 군간에 의미 있는 차이가 없었으나, 24시간 소변검사의 코르티솔 농도는 당뇨병군에서 의미있게 높았다. 2) 정맥당부하 검사 결과, 인슐린 감수성 지표인 Sl는쿠싱증추린」서 1.58±0.10[×10^(-4)(min^(-1)(μU/mL)^(-1)]로 정상 대조군의 3.37±0.49[×10^(-4)(min^(-1)(μU/mL)^(-1)]에 비해 의미있게 낮았으나(P=0.024), 쿠싱증후군 환자 중 NGT, IGT, DM 군간에 서로 통계적인 차이는 없었다. 3) SG는 정상 대조군과 쿠싱증후군 환자간에는 의미있는 차이가 없었고, 쿠싱 증후군에 있어서 당대사가 악화될수록 감소하는 경향을 보였으나 의미있는 차이는 없었다. 4) 인슐린 분비능의 지표인 AIRg는 정상인에 비해 전체 쿠싱증후군 환자의 경우 증가하는 경향을 보였으나 의미있는 차이는 없었다. 하지만 쿠싱증후군 환자중에서 당대사 상태에 따라 NGT군은 1299 (1297∼1310)(mu/g/min ×10^(-2))로 정상 대조군(368.9±98.6[mu/g/min ×10^(-2)]) 보다도 의미있게 높았고, DM군{202.2 (91.1~371.4) [mu/g/min ×10^(-2)}은 NGT군에 비해 의미있게 낮았다(P=0.0031). 5) 15명중 현재 완치 상태에 있는 6명에 대해 수술전과 후로 비교하였다. 수술 전 당대사 상태가 1명은정상, 1명은 내당능 장애, 그리고 4명은 당뇨병이었으나 수술 후 시행한 경구 당부하 검사상 모두 정상 당대사 상태를 보였다. 6) 수술 후 완치된 환자 6명에 있어 인슐린 감수성지표인 Sl는 수술전에 중앙값이 1.22[×10^(-4)(min^(-1)(μU/mL)^(-1)]로 대조군에 비해 의미있게 감고』어 있었으나(p.0.05), 수술후 10.95 [×10^(-4)(min^(-1)(μU/mL)^(-1)]로 정상 수준으로 회복되었고(P=0.0022), 인슐린 분비능을 나타내는 AIRg [mu/g/min ×10^(-2)] 값도 정상수준으로 회복되었다. 특히 인슐린 분비능의 회복양상은 혈당농도에 따라 판이하게 나타나서, 정상과 내당능장애 상태에 있던 2명은 수술전에 1201 [mu/g/min ×10^(-2)]로 증가되어 있던 AIRg 값이 수술 후 정상 수준으로 감소하였고, 수술 전에 당뇨병 상태에 있던 4명의 경우 245.9 [mu/g/min ×10^(-2)]로 인슐린 분비능이 감고il어 있었는데 이들은 수술 후 모두 정상 수준으로 증가되었다 (P=0.0286). 결론: 쿠싱증후군 환자에서 당대사 이상은 80%로 높은 유병률을 보였다. 모든 쿠싱증후군환자에서 인슐린 감수성은 정상인에 비해 저하되어 있어 말초조직의 인슐린 저항이 선행됨을 시사하며, 인슐린 분비능은 당대사의 정도에 따라 다르게 나타났는데, 정상 당대사군에서는 인슐린의 저항성을 극복할 만큼 정상 대조군보다 더 많은 양의 인슐린 분비를 하다가 고코르티솔혈증이 심할수록 인슐린 분비능의 감소로 당뇨병으로 진행됨을 확인할 수 있었고, 이런 인슐린 저항성과 인슐린 분비장애는 수술 후 다시 회복되는 가역적인변화를 보였다. Background: Glucocorticoid plays an important role in the control of carbohydrate metabolism. Patients with Cushing's syndrome have been reported to have an increased incidence of carbohydrate intolerance due to peripheral insulin resistance and hyperinsulinemia, although the exact incidence and nature of this disorder have remained unclear. Few results have been published about insulin resistance and insulin secretion according to the level of glucose concentration, or about the reversibility of such defects in patients with Cushing's syndrome. Methods: To assess the effect of glucocorticoid on the insulin sensitivity and insulin secretion in Cushing's syndrome, 15 patients with Cushing's syndrome were classified into 3 groups (normal glucose tolerance: NGT, impaired glucose tolerance: IGT, diabetes: DM) according to the degree of glucose tolerance based on the oral glucose tolerance test (OGTT). Insulin modified, frequently sampled, intravenous glucose tolerance test (FSIGT) was performed before and after curative surgery on these patients and on 15 healthy control subjects. Data were evaluated by non-parametric statistical analysis. Results: 1) Among the 15 patients with Cushing's syndrome, 3 (20%) were NGT, 4 (27%) IGT, and 8 (53%) DM, based on OGTT. Twenty-four hour urinary free cortisol (UFC) was significantly higher in the DM group. 2) Insulin sensitivity index (SI) of Cushing's syndrome was significantly lower than that of the control group p=0.0024), but was not significantly different among the three Cushing's syndrome groups of NGT, IGT and DM. 3) Glucose mediated glucose disposal (SG) (Ed- confirm this abbreviation; it does not seem to match the definition) of Cushing's syndrome was not significantly different from that of the control group. 4) Insulin secretion (AIRg) of Cushing's syndrome tended to be high, but it was not significantly different from that of control. However, according to the level of glucose concentration there was significant difference in AlRg among the three Cushing's syndrome groups p=0.0031); AIRg of DM was significantly lower than that of NGT. 5) After surgical treatment, parameters of insulin sensitivity and insulin secretion were normalized in 6 cured patients; 1 with NGT, 1 with IGT, and 4 with DM, preoperatively. Median SI of all 6 patients was significantly improved up to the normal range postoperatively p=0.0022). Median AIRg of these 6 patients was balanced around that of normal control postoperatively p=0.0286). Conclusion: Eighty percent of patients with Cushing's syndrome had abnormality of carbohydrate metabolism. Insulin sensitivity was significantly decreased in Cushing's syndrome. Insulin secretion was significantly higher only in the NGT and IGT groups of Cushing's syndrome. As the hypercortisolemia is exacerbated, insulin secretion is significantly decreased and causes DM, suggesting that glucocorticoid has a direct or indirect toxic effect on the pancreatic beta cell (J Kor SOC Endocrinol 18:392-403, 2003).

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.

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.

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.
