The purpose of this study was to investigate the effects of nutrition education focus on food habit, eating behaviors, dietary attitude, nutrition knowledge, and nutrients intake. The nutrition education was provided to 103 overweight and obese children in Chonbuk area. Nutrition education lessons were conducted 40 min/lesson, 12 times in year (6 times/semester). We assessed the change in knowledge using a questionnaire on food habit, eating behaviors, dietary attitude, nutrition knowledge and nutrients intake using 24 hr recall method. After the nutrition education, dietary habits were significantly improved. Especially, the answer of 'Don't eat when feel full' were significantly improved (boys (p<0.01), girls (p<0.05)). And the answer of 'Eat sugar meal frequently (chocolate, candy)' which is a dietary attitude question was significantly improved (girls (p<0.05)). There were positively changes in the dietary attitude and nutrition knowledge, but there were no significant differences after program. The results suggest that this nutrition education must be continue for positive food habit change in the long term.

The Purpose of this study was to investigate college students' attitude toward body weight control, health-related lifestyle and dietary behavior by their perception on body image and obesity index. The subjects were 871 nation- wide college students (330 male and 541 female students) participating in a nutritional education program via internet- A cross-sectional survey was conducted using a self-administered questionnaire via internet. The data were analyzed by a SPSS 10.0 program. Height and weight (p < 0.05), and the distribution of obesity index (p < 0.001) showed significant differences between male and female college students. As for self perception on body image, the necessity of body weight control and the experience of efforts to change the body weight, there were significant differences between male and female college students (p < 0.001). There were significant differences among groups by obesity index in the hours of exercise (p < 0.01), drinking (p < 0.01) and smoking (P < 0.001). As for methods of body weight control, all the groups by obesity index thought that program of body weight control by diet company is the most desirable method. Therefore, we must recognize that it is hard to correct health problems resulting from wrong lifestyle and dietary behavior fixed during college life and prepare a system for college students to obtain correct lifestyle and dietary behavior.

The purpose in this study was to develope the concept maps of sub-units included in 'resource management and environment' area of Home Economics(HE) as an advance organizer after analyzing the overlapped and connected contents between HE textbooks and those of other subject matters(Ethics, Social Studies, Sciences, and Physical Education) taught in the middle schools. The results of this study were as follows. First, the unit of 'resource facilitation and environment' of HE is dealt in Ethics. Specifically the overlapped content in this unit between HE and Ethics is the content of the savings of resources, recycling, and environment conservation. The unit of 'work and time of youth' is dealt in Ethics and Science. The overlapped content of this unit is that of the concept of 'work'. While Ethics focuses on the general concept of work, Science focuses on the scientific concept of work. Home Economics doesn't focus on the concept of work but on how to manage the work. In the unit of the 'adolescents and their consumption', there are many overlapped contents among three subject matters, HE, Ethics and Social Studies. Second, the 7 concept maps were developed by following the steps: (1) confirming the learning objectives presented in the 'resource management and environment' area of HE; (2) identifying the overlapped and connected contents between HE and other subject matters(Eethics, Social Studies, Sciences, and Physical Education); (3) organizing the overlapped and connected contents between HE textbooks and those of other subject matters.

The purpose of this study was to obtain information related to life style characteristics, school achievement and snacking behaviors among underweight and overweight adolescents in Ulsan area. The survey was carried out by self-questionnaires with 464 adolescents (333 underweight and 131 overweight). The results were as follows: Average BMI of the subjects was $19.81{\pm}3.10\;kg/m^2$ which was normal range, but average BMI of underweight and overweight were $16.90{\pm}1.19\;kg/m^2$ and $25.38{\pm}2.16\;kg/m^2$ respectively. The 49.5% of underweight and 94.7% of overweight students have correct perception about their body image. In the sleeping time, 58.9% of underweight and 66.4% of overweight students go to bed after PM 12 o'clock. In the regularity of eating breakfast, 68.5% of underweight and 67.9% of overweight students skipping breakfast at least 5 times per week. 32.6% of the subjects had snack once or more a day. Underweight students had more frequently ate snack than overweight students. The criteria of choosing snack were taste (77.4%), nutrition (9.3%), and price (6.3%). Food as snack they frequently had fruits, milk & milk products, cookies in order. Underweight students had more dodkboki & sundae, candy & chocolate and cake & bread than overweight students, although overweight students had more milk & yogurt than underweight students. The group who had a higher school record, they significantly had more fruits, milk & milk products (p < 0.01) and had not less nutritious foods (p < 0.001). This study may provide basic information on weight status, sleeping and snacking behaviors of adolescents. Therefore they should have nutrition education program to improve their life style and snacking patterns for underweight and overweight adolescents toward healthy weight.

Objective: This study evaluated the effects of a non-face-to-face obesity management program, implemented during the pandemic. Methods: The non-face-to-face obesity management program used the Intervention mapping protocol (IMP). The program was put into effect over the course of eight weeks, from September 14 to November 13, 2020 in 48 overweight and obese adults, who applied to participate through the Daegu Citizen Health Support Center. Results: IMP was first a needs assessment was conducted; second, goal setting for behavior change was established; third, evidence-based selection of arbitration method and performance strategy was performed; fourth, program design and validation; fifth, the program was run; and sixth, the results were evaluated. The average weight after participation in the program was reduced by 1.2kg, average WC decreased by 3cm, and average BMI decreased by 0.8kg/m² (p<0.05). The results of the health behavior survey showed a positive improvement in lifestyle factors, including average daily intake calories, fruit intake, and time spent in walking exercise before and after participation in the program. A statistically significant difference was seen (p<0.05). The satisfaction level for program process evaluation was high, at 4.57±0.63 point. Conclusion: The non-face-to-face obesity management program was useful for obesity management for adults in communities, as it enables individual counseling by experts and active participation through self-body measurement and recording without restriction by time and place. However, the program had some restrictions on participation that may relate to the age of the subject, such as skill and comfort in using a mobile app.

This study was intended to investigate food, exercise habits, perception of health status and the effects of nutrient intake of female college students. Food habits such as regularity of meal time, repast of breakfast, numbers of night snack per week and duration of meal were assessed via a self reporting questionnaire, and 24hrs recall method for nutrient intake was obtained from 155 female college students in Yangju-si. The mean height and weight of the subjects were $161.25{\pm}3.52cm$ and $52.26{\pm}4.52kg$, respectively. The average intakes of energy and nutrients were below the Korea recommended dietary allowance(RDA). Especially, The nutrient intakes(energy, protein, fat, fiber, calcium, iron, phosphorus, zinc, sodium, potassium, vitamin B6, niacin, vitamin C, folate, vitamin E, cholesterol) of the group in which the regularity of meal time per week was 5~7 days was significantly higher than the group in which the regularity of meal time was < 3 days (p<0.005). The nutrient intakes influenced by the food habit such as the regularity of meal time, skipping breakfast, and the numbers of night snack per week but did not differ in accordance with the regular exercise habits and perception of health status. These findings suggest that nutritional education based on female college students' food habits(regularity of meal time, skipping breakfast and night snacks per week, and duration of meal) may be required to improve dietary variety. It is considered that the improvement in dietary habits will contribute to the improvement of nutrition.

ICT 융합 스마트팜 내의 환경계측 센서, 영상 및 사양관리 시스템의 증가에도 불구하고 이들 장비에서 확보되는 데이터를 적절히 유효하게 활용하는 기술이 미흡한 실정이다. 돈사의 경우 가축의 복지수준, 성장 변화를 실시간으로 모니터링 및 예측할 수 있는 데이터 분석 및 모델링 기술 확보가 필요하다. 이를 위해선 가축의 생리적 변화 및 행동적 변화를 조기에 감지하고 가축의 복지수준을 실시간으로 감시하고 분석 및 예측 기술이 필요한데 이를 위한 대표적인 정보 통신 공학적 접근법 중에 하나가 Data mining 이다. Data mining에 대한 연구 수행에 필요한 다양한 소프트웨어 중에서 Open source로 제공이 되는 4가지 도구를 비교 분석하였다. 스마트 돈사 내에서 열환경 모델링을 목표로 한 데이터 분석에서 고려해야할 요인으로 데이터 분석 알고리즘 도출 시간, 시각화 기능, 타 라이브러리와 연계 기능 등을 중점 적으로 분석하였다. 선정된 4가지 분석 도구는 1) R(https://cran.r-project.org), 2) OpenCV(http://opencv.org), 3) OpenNN (http://www.opennn.net), 4) Orange(http://orange.biolab.si) 이다. 비교 분석을 수행한 운영체제는 Linux-Ubuntu 16.04.4 LTS(X64)이며, CPU의 클럭속도는 3.6 Ghz, 메모리는 64 Gb를 설치하였다. 개발언어 측면에서 살펴보면 1) R 스크립트, 2) C/C++, Python, Java, 3) C++, 4) C/C++, Python, Cython을 지원하여 C/C++ 언어와 Python 개발 언어가 상대적으로 유리하였다. 데이터 분석 알고리즘의 경우 소스코드 범위에서 라이브러리를 제공하는 경우 Cross-Platform 개발이 가능하여 여러 운영체제에서 개발한 결과를 별도의 Porting 과정을 거치지 않고 사용할 수 있었다. 빌트인 라이브러리 경우 순서대로 R 의 경우 가장 많은 수의 Data mining 알고리즘을 제공하고 있다. 이는 R 운영 환경 자체가 개방형으로 되어 있어 온라인에서 추가되는 새로운 라이브러리를 클라우드를 통하여 공유하기 때문인 것으로 판단되었다. OpenCV의 경우 영상 처리에 강점이 있었으며, OpenNN은 신경망학습과 관련된 라이브러리를 소스코드 레벨에서 공개한 것이 강점이라 할 수 있다. Orage의 경우 라이브러리 집합을 제공하는 것에 중점을 둔 다른 패키지와 달리 시각화 기능 및 망 구성 등 사용자 인터페이스를 통합하여 운영한 것이 강점이라 할 수 있다. 열환경 모델링에 요구되는 시간 복잡도에 대응하기 위한 부가 정보 처리 기술에 대한 연구를 수행하여 스마트팜 열환경 모델링을 실시간으로 구현할 수 있는 방안 연구를 수행할 것이다.
