Emamectin benzoate와 pyridaben에 대한 담배가루이의 잔효성과 섭식행동의 상관관계를 조사하였다. EPG의 파형은 non-probe time과 phloem phase time과 같은 파형을 신호개시 후 3시간 동안 기록하여 분석하였다. EPG 파형 중 non-probe time과 phloem phase time의 두 파형과 emamectin benzoate와 Pyridaben의 두 약제 간 잔효성의 상관관계 분석에서 모두 상관관계가 있는 것으로 나타났다. 잔효성은 두 약제 모두 2일까지는 50%로 비슷하였으나, 그 이후로는 pyridaben보다 emamectin benzoate가 급격히 감소하였다. EPG를 이용한 두 약제의 잔효성에 따른 구침을 찌른 시간과 체관부 섭식행동은 9일 이후부터 증가하는 경향을 보였으며, emamectin benzoate가 pyridaben보다 증가하는 속도가 빨랐다.

This study aimed to assess the association between the weight status and dietary behavior of preschool children. The survey included 412 preschool children aged 2-5 years in 31 childcare facilities in Gwangju. General characteristics of children and their mothers, weight, height, feeding type, complementary feeding, food allergy, and dietary behavior of children based on the Nutrition Quotient for preschoolers (NQ-P) questionnaire were considered. Children were classified into 4 groups by weight status; underweight, normal, overweight, and obese, based on the 2017 Korean National Growth Charts. The percentage of children in the respective groups was 5.3, 70.9, 10.7, 13.1%. Weight status was not related to breast feeding duration nor the starting time of complementary feeding. The NQ-P scores of underweight, normal, overweight, and obese groups were 55.4, 60.0, 60.8, 60.0. Among the three factors covered by the NQ-P, 'balance' and 'environment' scores of the underweight group were lower than that of other groups. Underweight children consumed beans, fish, and white milk less frequently. The 'moderation' scores of the overweight/obese group were lower than those of the normal or obese groups. Obese children more frequently ate processed meat and fast foods. Proper nutrition education is thus needed for not only obese children but also underweight children based on their age, along with their parents, and caregivers.

Studies on the feeding and resting behavior of Culex pipiens pallens, a possible vector of Japanese encephalitis in Korea, was carried out at Kobu-Ri, Kobu-Myon, Chongup Kun. Cholla Pukdo in 1967. 1. Indoor and outdoor human biting collections showed that 47.3 per cent Culex pipiens pallens were collected indoors and 52.7 per cent outdoors. 2.Feeding occurred throughout the night from dusk to dawn, with the peak period from 23:00-24:00 hours outside the house and from 24:00-01:00 hours inside. 3. Culex pipiens pallens females preferred man for their blood feeding to domestic animals. The results of human and cow biting collections showed that the feeding ratio between man and cow was 2.1 to 1. As to the feeding preference to the domestic animals, the ratio among cow, pig and horse was 7.3 to 5.1 to 5.4 4. Daytime resting collections showed that large numbers of Culex pipiens pallens females rest inside the house, especially in the bed room and the chicken pen. As temperatures increased, fewer mosquitoes resting indoors and more mosquitoes rest ing outdoors were caught. By means of sweep-net collections at outdoors resting places, a small number of Culex pipiens pallens mosquitoes were caught in such places as grass fields, vegetable fields, barley fields, bean fields, culverts, bomb shelters, and so on. A comparison between number of mosquitoes collected resting during the day in bedrooms and verandahs with resting collections in the same places at night showed that more mosquitoes were present at night. It was observed that the majority of the unfed females rested before feeding at night.

In this study, a rigid multi-body dynamic model has been developed for mechatronic analysis to evaluate dynamic behavior of a machine tool. The development environment was the commercialized analysis tool, ADAMS, for rigid multi-body dynamic analysis. A simplified servo control logic was implemented in the tool using its functions in order to negate any external tool of control definition. The advantage of the internal implementation includes convenience of the analysis process by saving time and efforts. Application of this development to a machine tool helps to evaluate its dynamic behavior against feeding its component, to calculate the motor torque, and to optimize parameters of the control logic.

This paper proposes a design of small controlled reception pattern antenna (CRPA) arrays using circular microstrip loops with frequency-insensitive characteristics. The proposed array consists of seven identical upper and lower circular loops that are electromagnetically coupled, which results in a frequency-insensitive behavior. To demonstrate the feasibility of the proposed feeding mechanism, the proposed array is fabricated, and its antenna characteristics are measured in a full-anechoic chamber. The operating principle of the proposed feeding mechanism is then interpreted using an equivalent circuit model, and the effectiveness of the circular loop shape is demonstrated by calculating near electromagnetic fields in proximity to the radiator. The results confirm that the proposed feeding mechanism is suitable to have frequency-insensitive behavior and induces strong electric and magnetic field strengths for higher radiation gain in extremely small antenna arrays.

In many machines handling lightweight and flexible media, such as automated teller machines(ATM) and printers etc., the media must transit an open space. In the paper feeding mechanism, it is important to feed the sheet without jamming under any conditions. To avoid sheet jamming, first we need to predict the behavior of the sheet exactly. The nonlinear theory of the dynamic elastica has often been used to a nonlinear dynamic deflection model. In this paper, the governing equation is derived and simulated by the finite difference method. The analysis has to include aerodynamic effect for more exact behavior analysis. For verification of the numerical simulation, the experiments were performed using high-speed camera and feeding mechanism. The experimental results show good agreement with the numerical simulations.

Purpose: This study aims to investigate the effects of an intervention of self-feeding for elderly residents who were eating with assistance or eating by himself/herself with spilling food. Methods: The Participants were 11 elderly people and 6 formal caregivers from 7 nursing homes in Korea. The intervention was to use the spoon and chopstick sets designed for compensating the weakened eating function. Both quantitative and qualitative data were collected through observation, structured questions, and in-depth interviews. Results: The mealtime was significantly increased by 3.2 minutes (p=.011) after the intervention. Three themes were extracted for the meaning of self-feeding expressed by the elders; fighting alone for self-feeding, pride of participating in the study, and burden for self-feeding and research participation. Caregivers expressed the meaning of the elder's self-feeding such as the regret of missed chances, facilitating rehabilitation, the increase of the eating pleasure and quality of care, and ambivalence. Conclusion: Self-feeding has become an opportunity to recognize life values for the elders in nursing homes; for the caregivers, to reconsider caring of the elderly. Posture and eating utensils were also important to improve self-feeding skills.

목적 : 자폐 스펙트럼 장애(Autistic Spectrum Disorders: ASD) 아동은 감각 처리, 제한된 흥미, 행동, 인지, 사회성, 구강 운동, 소화 등 복합적인 원인으로 인해 섭식장애가 흔하게 동반된다. 주요한 섭식장애 문제로는 식사 시간 행동 문제, 까다로운 먹기, 선택적 먹기, 새로운 음식 거부, 음식 다양성 저하 등이며 이로 인해 영양 섭취 및 건강 문제, 발달, 사회적 활동 참여 제한, 가족과 보호자 스트레스를 유발하기도 한다. 따라서 ASD 아동의 섭식장애를 조기에 확인하여 적절한 중재 제공과 적합한 평가도구 사용이 필요하다. 본 논문에서는 최신 문헌 고찰을 통해 ASD 아동의 섭식장애 평가도구에 대한 심도 있는 이해를 위한 고찰을 실시하였다. 연구방법 : 본 연구는 ASD, ASD의 섭식문제, ASD의 섭식평가 등의 키워드를 검색하여 최근 약 10년간의 선행연구를 바탕으로 ASD 섭식문제 평가도구를 분석하였다. 결과 : ASD 섭식장애 평가는 직접 평가와 간접 평가로 나뉘는데 그 중, 부모와 보호자가 아동의 전반적인 상황을 척도화 한 질문지나 평가도구로 측정하는 간접 평가가 주로 사용되고 있었다. 평가는 주로 식사 시간 중 아동이 보이는 섭식 행동, 구강 및 미각 관련 감각 처리, 음식 선택 및 선호도를 확인하였으며 보호자의 섭식 태도가 아동의 섭식 행동에 미치는 영향을 평가하기도 하였다. 결론 : ASD 아동의 섭식 장애 평가는 1) 식사 시간 섭식 행동, 2) 감각 처리, 3) 섭취 음식, 4) 기타로 구분되었다. ASD 아동의 주요한 섭식장애 특징은 매우 다양하기 때문에 종합적인 평가가 이루어져야 하지만 아직 제한적이다. 또한 구강 운동 기능, 소화 등 추가적인 영역의 평가도 고려되어야 할 것으로 보인다. 작업치료사 등 연하재활 전문가는 ASD 아동의 섭식 문제, 행동, 감각 등에 대한 기본적인 이해를 바탕으로 한 종합적인 평가도구를 적용해야 할 것이다.

Obesity is increasing worldwide and has become a major health burden in Western societies affecting every third American and every fifth European. Obesity makes a major contribution to morbidity and mortality, predisposing individuals to cardiovascular disease and diabetes. Many new substances are currently being investigated for their usefulness in the pharmacotherapy of obesity. Most anti-obesity drugs can be divided into four groups: those that reduce food intake; those that alter metabolism; those that increase thermogenesis; and those that regulate hormone involved in feeding behavior. In this article we review these and other agents available in various countries for the treatment of obesity. Perhaps more importantly, we have focussed on areas of potential productivity in the future. Over the last 5 or so years, this impetus in obesity research has provided us with exciting new drugs targets involved in the regulation of feeding behavior and cellular mechanism involved in energy expenditure. Recent development in the quest for control of human obesity include the discovery of hormones, neuropeptides, receptors and transcription factors involved in feeding behavior, metabolic rate and adipocyte development. For developing new, perhaps even more specific pharmacological agents, further research is needed to understand the individual different genetic and physiological basis of obesity. It remains the hope of research scientists that in the not too distant future we shall see a new class of anti-obesity drugs arising logically from the molecular biology revolutions.

The purpose of this study was to determine the correlation between young children's picky eating behavior and mother's attitudes, beliefs and practices regarding the eating habits of children. Using a sample of 304 mothers of four or five year-old children, confirmatory factor analysis was conducted to test a 7 factor model, which included mother's beliefs and practices related to the feeding of their children. Following this, a t-test was conducted to examine the differences between the feeding behaviors of mothers of both of picky and non-oicky eaters, respectively. The results indicated that picky eater's eating behaviors were positively related to the pressures exerted by mothers and negatively related to the mother's concerns about their child's weight and child's BMI. These findings suggest that the pressures mothers exert upon their children to eat, their child's weight and picky eating behaviors are correlated to each other.
