현재 일반 중,고등학교에서 장애학생을 만나는 일은 매우 흔한 일이 되었다. 하지만 일반교육과정에 접근하여 장애학생이 통합수업에 참여하게 하는 교육과정적 통합은 제대로 이루어지지 않고 있는 현실이다. 따라서 본 연구에서는 과학교과를 선택하여 자기결정교수학습모델(SDLMI)을 활용한 교수적 지원을 실시, 통합된 중학교 장애학생들의 과학과 수행평가 성취도와 수업참여행동의 향상에 어떠한 영향을 미치는지 알아보았다. 본 연구의 참여자는 서울시내 공립중학교에 소속되어 있는 특수교육 대상자 3명이며, 실험은 단일대상연구방법으로 대상자간 중다 간헐 기초선 설계 방법을 사용하여 연구 참여자의 소속학교에서 실시되었다. 실험 결과, 3명의 연구 참여자 모두 중재를 시작한 이후, 수업참여행동이 기초선 구간보다 향상되었고, 그 행동은 유지 및 다른과목에서도 일반화 되었다. 중재 기간동안 실시된 과학과수행평가에서도 모두 점수가 향상되었으며, 일반화를 위해 측정된 다른 과목의 수행평가 점수도 모두 중재 실시 전보다 향상되었다. 또한 목표달성척도(GAS)를 통해 연구 참여자 본인이 스스로 세운 수행평가 목표점수에도 2명의 학생이 도달하였다. 본 연구는 통합된 장애학생들이 스스로 목표를 정하고, 그 목표를 달성하기 위해 노력하는 과정에서 학생들의 잠재력이 발현되고, 기존의 교사 주도적 학습전략이 아닌 학생 주도적인 학습전략의 활용으로 통합된장애 학생들의 일반학급에서의 수업참여행동 및 수행평가 성취도의 향상을 가져왔다는 것에 의의가 있다. According to the Korean annual report for special education in 2012, 70.7% of students with disabilities have studied in general education classrooms. Especially, in spite of that science class has more possibility to allow students to interact with other classmates through experiments and activities, students’ participations are still limited. In this respect, this study investigated the effects of instructive supports with SDLMI on performance assessment and academic engagement behaviors of 3 students with disabilities. Multiple probe design across subjects was applied for this study including baseline, intervention, and maintenance period. Effects of generalization of intervention were also examined in other subjects. The results of this study showed positive influence of instructional supports with SDLMI on students’ performance and academic engagement behaviors in classrooms by analyzing data observed in class and performance worksheets. Based on the results, this study has proved that the students with disabilities would be able to enhance their potential to improve their performance and academic engagement in class along with achieving their goals by using various student-directed instructional strategies.

국내 육종 사과 품종인 ‘홍로’의 과피와 과육에서 발현되는 단백질체를 추출하여 이차원 전기영동으로 분리하였다. 그 결과 대부분의 단백질들은 과피와 과육에서 유사한 정도로 발현되었으나, 30개의 단백질 spot들은 과피 또는 과육에서의 발현 정도가 2배 이상 차이가 났다. 이들 중 25개는 과피에서, 5개는 과육에서 더 높게 발현되었다. 이들 단백질들을 MALDI-TOF/TOF로 분석한 결과, 과피에서 더 높게 발현된 단백질 spot들 중 18개는 각각의 기능을 갖는 단백질로 동정 되었고, 나머지 7개는 기능이 밝혀지지 않은 것으로 동정되었거나 미동정 되었다. 과육에서 더 높게 발현된 단백질 spot들의 경우 2개는 각각의 기능을 갖는 단백질로 동정 되었고, 나머지 3개는 미동정 되었다. 과피에서 더 높게 발현된 단백질은 에틸렌의 생합성과 관련된 1-aminocyclopropane-1-carboxylate oxidase homolog(spot 21번), 이차대사산물의 생합성과 관련된 acetyl-CoA acetyltransferase, cytosolic 1(spot 148), acetyl-CoA acetyltransferase, cytosolic 1-like(spot 316) 및 8-hydroxygeraniol dehydrogenase-like(spot 348), 광합성과 관련된 oxygen-evolving enhancer protein 1, chloroplastic(spot 210) 및 ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit(spot 273), 생체방어 및 스트레스 반응과 관련된 (+)-neomenthol dehydrogenase-like(spot 216 및 219), formate dehydrogenase, mitochondrial(spot 305), glutathione S-transferase-like(spot 483 및 484) 및 acidic endochitinase SE 2-like, partial(spot 391 및 392), 항산화효소인 L-ascorbate peroxidase 2(spot 221), 알레르기 관련 단백질인 MLP-like protein 34(spot 406), major allergen Mal d 1(spot 451 및 452) 및 major allergen Mal d 1.06A01(spot 457)이었다. 한편 과육에서 더 높게 발현된 단백질은 protein folding과 관련된 chaperonin 60 subunit alpha 1, chloroplastic(spot 8) 및 탄수화물 대사와 관련된 NADP-dependent D-sorbitol-6-phosphate dehydrogenase(spot 380)이었다. 이상의 연구 결과들은 사과의 육종, 저장, 품질, 환경에 대한 내성 등과 관련된 광범위한 연구에 유용하게 이용될 수 있을 것으로 사료되었다. The proteome expressed in the peel and flesh of ‘Hongro’, a domestic breeding apple cultivar, was extracted and separated by two-dimensional electrophoresis. Most of the proteins were expressed at similar levels in the peel and flesh, but 30 protein spots showed a difference of more than two times higher in expression level in the peel and flesh. Of these, 25 were higher in the peel and 5 were higher in the flesh. By analyzing these proteins with MALDI-TOF/TOF, 18 of the protein spots that were higher in the peel were identified as proteins with their respective functions, and the remaining 7 were identified as having unknown function or were unidentified. In the case of the protein spots expressed higher in the flesh, two were identified as proteins having respective functions, and the other three were unidentified. Proteins more highly expressed in the peel were 1-aminocyclopropane-1-carboxylate oxidase homolog (spot 21) related to the biosynthesis of ethylene; acetyl-CoA acetyltransferase (spot 148), cytosolic 1, acetyl-CoA acetyltransferase, cytosolic 1-like (spot 316) and 8-hydroxygeraniol dehydrogenase-like (spot 348) related to the biosynthesis of secondary metabolites; oxygen-evolving enhancer protein 1, chloroplastic (spot 210), and ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit (spot 273) related to the photosynthesis;(+)-neomenthol dehydrogenase-like (spot 216 and 219), formate dehydrogenase, mitochondrial (spot 305), glutathione S-transferase-like (spot 483 and 484), and acidic endochitinase SE 2-like, partial (spot 391 and 392) related to the biological defense and stress response; and antioxidant enzyme L-ascorbate peroxidase 2 (spot 221), MLP-like protein 34 (spot 406), major allergen Mal d 1 (spot 451 and 452), and major allergen Mal d 1.06A01 (spot 457) related to allergies. On the other hand, proteins that were more highly expressed in the flesh were chaperonin 60 subunit alpha 1, chloroplastic (spot 8) related to protein folding, and NADP-dependent D-sorbitol-6-phosphate dehydrogenase (spot 380) related to carbohydrate metabolism. These results will be useful in a wide range of studies related to apple breeding, storage, quality, and environmental tolerance.

목적: 위장관의 내장 감각능 이상은 기능성 소화불량증의 중요한 병인으로 알려져 있으나 위장관의 감각을 지각하는 기전은 정확히 알려져 있지 않다. 세로토닌은 위장관의 운동과 감각능을 조절하는데 중요한 역할을 한다. 저자는 5-hydroxytryptamine-4 (5-HT4) 수용체 부분 작용제인 tegaserod가 건강인에서 소장의 감각능과 팽창도에 어떠한 영향을 주는지 알아보고자 하였다. 대상 및 방법: 건강 지원자 16명을 대상으로 위약이나 tegaserod (6 mg 하루 2회) 두가지 약물중 한 약제를 단일 맹검, 무작위 순서로 3일간 전투약한 후 검사를 시행하였다. 십이지장 3부에 최대 용적 120 mL의 풍선이 부착된 검사관을 위치시킨 후 바로스타트에 연결하여 소장의 팽창도 및 소장의 감각능을 평가하였다. 풍선의 용적을 단계적으로 증가시키면서 최초 인지 용적(처음으로 감각을 느끼는 용적), 최대 인내 용적(불편감/통증으로 참기 힘들때의 용적)을 기록하고 압력 변화를 관찰하여 소장 팽창도를 계산하였다. 소장 감각능은 20 mL, 40 mL, 60 mL의 3가지 팽창 자극을 무작위 순으로 3회씩 주어 피험자가 느끼는 감각을 시각적 선형척도에 기록하게 하여 평가하였다. 고칼로리 유동식인 엔슈어를 지속적으로 소장에 주입하면서 다시 무작위 순서로 3가지의 팽창자극을 주면서 피험자의 감각을 측정하였다. 결과: Tegaserod 투여군의 소장 팽창도는 2.59±0.74 mL/mmHg로 위약 투여군의 소장 팽창도 2.25±0.42mL/mmHg에 비해 유의한 차이가 없었다. tegaserod 투여군과 위약 투여군 사이에 최초 인지 용적의 차이는 없었지만 최대 인내 용적은 tegaserod 투여군에서 55.7±12.9 mL로 위약투여군 41.7±7.3 mL에 비해 유의하게 높았다( p<0.05). 20,40, 60 mL의 팽창자극을 하였을 때 오심, 팽만감, 불편감/통증 및 총 감각 지수는 tegaserod 투여군과 위약 투여군 사이에 차이가 없었다. 유동식을 주입하면서 팽창자극을 주었을때에도 두 군간에 팽창 자극에 대한 감각 점수에는 유의한 차이가 없었다. 결론: Tegaserod군과 위약군 사이에 빠른 위상성 팽창 자극에 대한 감각의 차이는 없었으나 단계적 팽창 자극에 대한 최대 인내 용적이 tegaserod군에서 위약군에 비해 유의하게 높아 tegaserod가 소장의 감각을 완화시키는 것으로 추정할 수 있다. Backgr ound/Aims: Disturbances in visceral perception contribute to postprandial symptoms in patients with functional dyspepsia. However, the mechanism of perceiving sensation has not been clearly defined. Our aim in this study was to evaluate the effect of tegaserod on compliance and visceral perception in the proximal small intestine. Methods: Sixteen healthy subjects were included in this study. Subjects underwent single blinded randomization to either a placebo group or a regimen group of 3-day pretreatment with tegaserod (6 mg bid). Thirty minutes after the insertion of a balloon-equipped, double-lumen tube into the duodenum, we sequentially measured the compliance and maximal tolerable volume to stepwise balloon distension. The maximum volume of the balloon was 120 mL, and an electronic barostat was used to maintain a constant volume within the balloon. Sensory function was assessed by grading accompanying symptoms of nausea, fullness, and abdominal discomfort/pain during random-ordered isovolumetric ditension of the balloon at volumes of 20 mL, 40 mL, and 60 mL. We made additional assessments on sensory function by slightly modifying the above method of randomized balloon distension to include continuous infusion of liquid meal into the tube. Results: There was no significant difference in compliance between the two groups. Maximal tolerable volume was significantly larger in the tegaserod group than in the placebo group (55.7±12.9 mL vs. 41.7±7.3 mL, p<0.05). Perceived sensations measured using the visual analogue scale during random ordered rapid phasic distension (20, 40, 60 mL) did not reveal differences between the two groups. Conclusions: Tegaserod had no effect on perceived sensation during rapid phasic distension, but it did increase the maximal tolerable volume during stepwise distension. These results suggest that tegaserod reduces the sensitivity to small bowel distension in healthy subjects. (Kor J Neur ogastr oenter ol Motil 2004;1:35-42)

A driver assistance system is critical to improve a convenience and stability of vehicle driving. Several systems have been already commercialized such as adaptive cruise control system and forward collision warning system. Efficient vehicle detection is very important to improve such driver assistance systems. Most existing vehicle detection systems are based on a radar system, which measures distance between a host and leading (or oncoming) vehicles under various weather conditions. However, it requires high deployment cost and complexity overload when there are many vehicles. A camera based vehicle detection technique is also good alternative method because of low cost and simple implementation. In general, night time vehicle detection is more complicated than day time vehicle detection, because it is much more difficult to distinguish the vehicle's features such as outline and color under the dim environment. This paper proposes a method to detect vehicles at night time using analysis of a captured color space with reduction of reflection and other light sources in images. Four colors spaces, namely RGB, YCbCr, normalized RGB and Ruta-RGB, are compared each other and evaluated. A suboptimal threshold value is determined by Otsu algorithm and applied to extract candidates of taillights of leading vehicles. Statistical features such as mean, variance, skewness, kurtosis, and entropy are extracted from the candidate regions and used as feature vector for SVM(Support Vector Machine) classifier. According to our simulation results, the proposed statistical feature based SVM provides relatively high performances of leading vehicle detection with various distances in variable nighttime environments.

The purpose of this study was to examine the effects of pilates mat exercise and a ballet program on body fat percentage, blood lipid, and adiponectin in obese middle-aged women. The pilates mat exercise and ballet program were conducted with obese middle-aged women for eight weeks in the physical fitness center located in D-gu. Based on the results, the following conclusions were obtained. First, the exercise group conducting the pilates mat exercise and ballet program showed a significant decrease in the body fat percentage. Second, for blood lipid, the exercise group conducting the pilates mat exercise and ballet program had in total cholesterol, significant differences in triglyceride and LDL cholesterol. Third, the exercise group conducting the pilates mat exercise and ballet program showed a significant increase in adiponectin, suggesting the positive effect of the exercise. In conclusion, the pilates mat exercise and ballet program had positive exercise effects on the decrease in body fat percentage in obese middle-aged women. To prevent ongoing osteoporosis after middle age, the pilates mat exercise can be recommended to enhance muscle strength. Moreover, triglyceride and LDL cholesterol, which are risk factors of metabolic syndrome, were effectively decreased and the adiponectin in the blood, which is an obesity indicator, was increased. It suggests a positive effect on obesity improvement. Therefore the pilates mat exercises, which is good to enhance flexibility and muscle strength, and the ballet program, which is effective for aerobic exercise and posture correction, can be recommended to obese middle-aged women. It will greatly contribute to giving them the fun of exercise and promoting their health.

The blind spot is an area where drivers visibility does not reach. When drivers change a lane to adjacent lane, they need to give an attention because of the blind spot. If drivers try to change lane without notice of vehicle approaching in the blind spot, it causes a reason to have a car accident. This paper proposes a night-time blind spot vehicle detection using cameras. At nighttime, head-lights are used as characteristics to detect vehicles. Candidates of headlight are selected by high luminance feature and then shape filter and kalman filter are employed to remove other noisy blobs having similar luminance to head-lights. In addition, vehicle position is estimated from detected head-light, using virtual center line represented by approximated the first order linear equation. Experiments show that proposed method has relatively high detection porformance in clear weather independent to the road types, but has not sufficient performance in rainy weather because of various ground reflectors.

This research intended to investigate the consciousness and consumption behavior for processed foods and their preference among 330 male and female high school students in Daegu. The preferences for the processed food was highest for the ‘coffee & sports drinks’ and the average score of female students are significantly higher than their counterparts(p<0.05). The group with high dietary behavior showed significantly high preference for "dairy products" for the processed foods. Those who have low dietary behavior showed significantly high score for sweets such as ‘ice cream, candy and chocolate’. Female students put higher emphasis on ‘food’ and ‘expiration date’ for processed foods than male students. The group with higher dietary behavior score gives significantly higher score on ‘nutrition’ when selecting the processed foods. In general, consciousness on processed food was negative. Our results indicated that nutrition education for high school students should focus on selecting clean and nutritious products rather than taste, consuming proper amounts, and avoiding junk foods.
