어머니에 대한 사회적 지지와 어머니와 자녀의 상호작용이 유아의 문제행동에 미치는 영향
김갑순,박윤조 한국보육학회 2016 한국보육학회지 Vol.16 No.3
The Purpose of this study was to examine the effect of Mother Social Support and Mother-Child Interaction on Children’s Problem Behavior. The data of 1614 children aged 5 years old and their mothers were collected from 6th Korean Child Survey Panel(2013) by Korea Institute of Child Care and Education. Data were analyzed using Pearson’s correlations, stepwise multiple regressions by SPSS 18.0. According to the result, there were significant relationships among age, education of mother’s demographic background, mother social support, mother-child interaction, and children’s problem behavior. Next, as well as mother’s demographic background, mother social support was indicated effective variance on mother-child interaction. Third, friends and colleagues of mother of mother social support and mother-child interaction were emphasized effective variances on child problem behavior. This study has a significance in some respects and leave positive implications for reduce the child problem behavior. 본 연구는 어머니에 대한 사회적 지지와 어머니와 자녀의 상호작용이 유아의 문제행동에 미치는 영향을 살펴보았다. 이를 위해 육아정책연구소에서 수행한 2013년도 제 6차 아동패널자료를 사용하였으며 연구대상은 만5세 유아 1614명과 그들의 어머니였다. 수집된 자료는 SPSS18.0을 이용하여 Pearson적률 상관분석 및 단계적 투입법에 의한 다중회귀분석을 실시하였다. 연구 결과는 첫째, 어머니의 인구학적 배경 중 연령과 학력, 그리고 어머니와 자녀의 상호작용, 어머니에 대한 사회적지지, 그리고 유아의 문제행동 간은 서로 유의미한 관련이 있었다. 둘째, 어머니의 인구학적 배경 뿐 아니라 어머니에 대한 사회적 지지가 어머니와 자녀의 상호작용에 영향을 미치는 것으로 나타났다. 셋째 어머니의 사회적지지 중 친구 및 동료지지와 어머니와 자녀의 상호작용이 유아의 문제행동에 영향을 주는 것으로 나타났다. 따라서 어머니의 사회적지지 중 친구 및 동료지지를 활용한 유아의 문제행동 감소를 위한 노력이 요구되어진다.
Design of a Robot’s Hand with Two 3-Axis Force Sensor for Grasping an Unknown Object
김갑순 한국정밀공학회 2003 International Journal of Precision Engineering and Vol.4 No.3
This paper describes the design of a robots hand with two fingers for stably grasping an unknown object, and the development of a 3-axis force sensor for which is necessary to constructing the robots fingers. In order to safely grasp an unknown object using the robots fingers, they should measure the forces in the gripping and in the gravity directions, and control the measured forces. The 3-axis force sensor should be used for accurately measuring the weight of an unknown object in the gravity direction. Thus, in this paper, the robots hand with two fingers for stably grasping an unknown object is designed, and the 3-axis force sensor is newly modeled and fabricated using several parallel-plate beams.
Development of a 6-axis robot's finger force/moment sensor for stable grasping of an unknown object
김갑순 한국정밀공학회 2004 International Journal of Precision Engineering and Vol.5 No.3
This paper describes the development of a 6-axis robots finger force/moment sensor, which measures forces (x-direction force), and , and moments (x-direction moment), and simultaneously, for stable grasping of an unknown object. In order to safely grasp an unknown object using the robots gripper, the force in the gripping direction and the force in the gravity direction should be measured, and the force control should be performed using the measured forces. Also, the moments , and to accurately perceive the position of the object in the grippers should be detected. Thus, the robots gripper should be composed of 6-axis robots finger force/moment sensor that can measure forces , and , and moments , and simultaneously. In this paper, the 6-axis robots finger force/moment sensor for measuring forces , and , and moments , and simultaneously was newly modeled using several parallel-plate beams, designed, and fabricated. The characteristic test of the fabricated sensor was performed, and the result shows that interference errors of the developed sensor are less than 3%. Also, Robots gripper with the 6-axis robots finger force/moment sensor for the characteristic test of force control was manufactured, and the characteristic test for grasping an unknown object using the sensors was performed using it. The fabricated gripper could grasp an unknown object stably. Thus, the developed 6-axis robots finger force/moment sensor can be used for robots gripper.
극저온 환경에서 스트레인 게이지의 게이지상수 및 변형률 측정에 관한 연구
김갑순,주진원 대한기계학회 1993 대한기계학회논문집 Vol.17 No.9
The characteristic test for gage factors of temperature self-compensated strain gages at cryogenic temperature is presented. By joining the international round robin test on electrical strain gages at cryogenic temperatures, the gage factors of three kinds of widely-used strain gages are obtained at the room temperature, the temperatures of liquid nitrogen and liquid helium. The calibration system which produce precise bending strain is by mechanical loading at cryogenic temperature. This paper also presents the creep characteristic of strain gages at maximum strain level.
