그림책을 활용한 반편견 교육활동이 유아의 장애 수용 인식 및 태도에 미치는 영향
원계선,최일선 국립특수교육원 2004 특수교육연구 Vol.11 No.2
본 연구의 목적은 그림책을 활용한 반편견 교육프로그램이 만 5세 유아의 장애에 대한 인식 및 태도에 미치는 효과를 밝히는 데 있다. 본 연구의 대상은 이천 시 소재 유치원의 만 5세 일반 유아 50명으로, 실험 집단 유아 25명에게는 그림책을 활용한 반편견 교육활동을, 통제집단 유아 25명에게는 정규 유아교육활동을 시행하였다. 연구결과, 두 집단 유아들 간에 장애인에 대한 상호작용의도, 인식 및 수용태도에 있어서 유의한 차이가 있는 것으로 나타났다. 이는 장애와 관련된 그림책을 선정하여 반편견 교육활동을 시행한 것이 일반 유아들의 장애에 대한 인식과 태도에 긍정적인 영향을 끼친다는 점을 시사한다. This study investigates the effects of the anti-bias program using literature on children's intentions, recognitions and attitudes toward children with disabilities. In this study, the subjects were 50 children without disabilities 5 years old kindergarten children. They were placed to an experimental or a control group, with 25 children in each other. While normal regular program was provided for the control group, the anti-bias program through literature was applied to the experimental group for 4 weeks. Significant differences were showed between the pre and post-test scores in intentions, recognitions and attitudes toward the disabled. This results indicates that the anti-bias program using literature affects positive influences to children's intentions, recognitions and attitudes toward children with disabilities.
Comprehensive Plan to Reduce Sodium and Sugar Intake
Gye-Sun Choi 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10
While socioeconomic costs increase resulting from excessive consumption of sodium and sugar which triggers to increase in chronic diseases, the cost can be highly saved by improving eating habit. The daily sodium intake in South Korea is still about 1.6 times higher than recommended daily intake of the WHO standard, and the children’s daily sugar intake also exceeds the WHO recommended value. The sodium and sugar reduction policy being promoted so far contributes to declining intake to 32% for sodium and 19% for sugar. Recognized for heightening public awareness for reducing sodium and sugar intake, MFDS was appointed as an international excellent institution in preventing and managing chronic diseases such as obesity and diabetes. However, due to the lack of production and distribution base for sodium and sugar reduced products and insufficient measures to create the healthy eating environment, it is necessary to present a strategy to foster healthy eating habits for our daily life. To this end, a survey on the national dietary environment was conducted and its result showed that interests and demands for healthy diet are increasing since consumption patterns have changed to value quality of life, non-face-to-face transactions including online shopping are accelerated due to COVID-19 and big data analysis and artificial intelligence utilization in the food management sector is increasing. Furthermore, examining overseas trends, the WHO strongly recommends the target sodium intake be maintained by less than 2,000 mg and the sugar intake be maintained within 10% of total energy intake. The goal of the 3rd comprehensive plan for sodium and sugar reduction is to maintain daily sodium intake at 3,000 mg or lower by 2025 and to control sugar intake from processed food within 10% of the recommend daily total calorie intake. The first strategy is to flexibly operate labelling standards for sodium and sugar reduced products by establishing production base, to expand the mandatory list of nutrition labelling for processed food, to support development and utilization of sodium and sugar substitute preparations, and to utilize integrated nutrition information. The second strategy is to expand consumers’ access to sodium and sugar-reduced products by fostering the environment for distributing and purchasing such products, to strengthen nutrition labelling for food such as delivery food, and to boost distribution and consumption of sodium and sugar-reduced products. The third strategy is to induce changes in consumers’ eating habits, thereby developing and distributing personalized nutrition information utilization programs, expanding dietary education and promotion to the public for each life cycle, and implementing a campaign to reduce sodium and sugar participation. The fourth strategy is to establish an institutional foundation for privately led reduction policies and a scientific statistics system for the information on sodium and sugar. To do this, the government plans to push for four major strategies, 12 projects and 35 detailed tasks over the next five years aiming to realize sustainable reduction of sodium and sugar from production to consumption.

본 연구에서 확립한 분석법으로 총 393건의 시료를 분석한 결과 넙치에서 아목시실린 9건, 장어에서 옥소린산 4건과 플루메퀸 1건이 검출되었다. 아목시실린의 검출농도는 0.009-0.078 mg/kg의 범위를 나타내었고, 옥소린산의 검출농도는 0.02-0.20 mg/kg의 범위를 나타내었다. 플루메퀸은 잔류허용기준(0.5 mg/kg) 이하의 농도로 장어 1건(0.03 mg/kg)에서 검출되었다. The present study was performed to validate an analytical method for veterinary drugs, including amoxicillin, ampicillin, oxolinic acid and flumequin, in meat, fish, and their products as established in the 2007 Korea Food Code, and to monitor the respective drugs in 6 kinds of foods, namely beef, pork, flatfish, rockfish, freshwater eel and shrimp. Additionally, an HPLC-ESI-MS/MS method was developed for the qualification of these veterinary drugs. As a result of monitoring, these drugs were detected in 14 (3.6%) out of 393 samples. In particular, amoxicillin was detected in 9 flatfish samples, and oxolinic acid and flumequin were detected in 4 samples and 1 sample of freshwater eel, respectively. The detection levels of amoxicillin ranged from 0.009 to 0.078 mg/kg, in which 1 sample of flatfish contained more than the MRL (0.05 mg/kg). Flumequin detected in 1 sample of freshwater eel, was less than the MRL (0.5 mg/kg). Therefore, the majority of detected levels were less than the MRLs, with the exception of 2 samples showing amounts that were 1-2 times higher than the MRLs. The detected veterinary drugs were identified and confirmed by the HPLC-ESI-MS/MS method created in this study.
Compact band-notched ultrawideband Y-shaped antenna with dual inverted-L slots
Choi, By Sun-Ho,Jeong, Gye-Taek,Park, Ho-Hwan,Lee, Hwa-Choon,Kwak, Kyung-Sup Wiley Subscription Services, Inc., A Wiley Company 2008 MICROWAVE AND OPTICAL TECHNOLOGY LETTERS Vol.50 No.11
<P>In this work, a novel band-notched ultrawideband (3.1–10.6 GHz) Y-shaped microstrip patch antenna with dual inverted-L slots is presented. The proposed antenna consists of a wideband Y-shaped monopole antenna and dual inverted-L slots, producing band-notch characteristics. To obtain sufficient bandwidth when the return loss (RL) < −10 dB, but still generate band-notch characteristics, we propose that a partial ground plane, a coaxial probe source, and two inverted-L slots can be used. The measured bandwidth of the fabricated antenna is from 2.96 to 4.85 GHz (from 6.05 to 12.65 GHz when the RL < −10 dB), and the frequency notch band is from 5.15 to 5.825 GHz. The measured gain is 3.66–4.58 dBi, which drops to −3.80 dBi in the notch band. The azimuth and elevation of the experimental 3-dB beam width (HPBW) are 72.58° and 88.59° at 7.0 GHz, respectively. © 2008 Wiley Periodicals, Inc.

본 논문은 보행중인 시각장애인에 장착된 카메라로부터 획득한 영상에서 보도와 차도 영역을 구분하기 위한 영역분할 기법과 질감 특징추출 기법에 대해 제안한다. 허프 변환 알고리즘을 이용한 라인검출을 통해 도로 경계선을 검출하고, 분할된 영역을 원근에 따라 3단계의 레벨로 구분한다. 그리고 분할된 영역들의 질감 특징성분을 추출함으로써 보도와 차도영역으로 분리한다. 보도블록이 가지는 복잡하고 다양한 특성의 패턴과 차도의 균일한 질감을 가진 영역의 특성을 비교하기 위하여 회전에 강건한 LBP, GLCM 질감 특징성분들을 이용함으로써 두 영역을 구분하였다. 제안된 방법은 주간과 야간 영상에 대해 실험한 결과 조도의 변화에 강건하게 영역을 분리할 수 있었고, 또한 보행자와 장애물이 많은 영상에서도 회전이나 폐색에 관계없이 영역 분리가 가능함을 확인하였다. In this paper, we propose an region segmentation and texture based feature extraction method which split the pavement and roadway from the camera which equipped to the visually impaired person during a walk. We perform the hough transformation method for detect the boundary between pavement and roadway, and devide the segmented region into 3-level according to perspective. Next step, split into pavement and roadway according to the extracted texture feature of segmented regions. Our walking assistance system use rotation-invariant LBP and GLCM texture features for compare the characteristic of pavement block with various pattern and uniformity roadway. Our proposed method show that can segment two regions with illumination invariant in day and night image, and split there regions rotation and occlution invariant in complexed outdoor image.
