This study was started with concern about problem of increasing physical and personal injury caused by traffic accidents, despite of technological advances in transportation. As the vehicles, which is currently produced, informs the driver only detecting the proximity of an object by the front and rear sensor, this study implemented the color detection algorithm, the circular shape recognition algorithm, and the distance recognition algorithm and built the accident prevention beyond accident perception, which commends to avoid the object or to stop the robot, if object was detected by algorithms. For the simulation, we made the Arduino vehicle robot equipped with compact wireless communication camera and confirmed that the robot successfully avoids an object or stops itself in simulated driving.

This study sought to find out what the most ideal and appropriate native English speakers-Korean English teacher cooperative class model and the defining factors for organizing effective cooperative classes in the English education environment of our country. To achieve this goal, a total of 165 sixth graders of five elementary schools in Seoul were subject to the study. For about a month from April 1 to April 30, 2019, the survey and statistical analysis were conducted, including multiple return analysis, correlation analysis, cross analysis, and t/F verification. In summary, the results of the study are as follows. First, it was found that among the recognition of cooperative classes between native English speakers and Korean English teachers, it affected the defining factors in the order of class-related skills, task orientation, teaching-learning strategies, and motivation. Second, based on learner characteristics, the difference in perception of cooperative classes between native English speakers and Korean English teachers was verified, and the perception of native-Korean English teachers' cooperative classes was different depending on gender and the type of English cooperative classes currently participating, but the recognition of native-Korean English-Korean English cooperative classes, which were statistically significant, was not confirmed. Third, according to learner characteristics, the difference in the definition factors of the learner was verified and the difference between the sexes occurred, but the learner-defined factors according to the current type of English cooperative class did not occur. Also, there was no difference in the definition factors of scholars according to the type of English cooperative classes desired.

The purpose of this study is to identify the perception of New-Hanbok Skirts that female consumers have and to analyze the design preference based on the analysis of designs of skirt products currently in distribution. Based on the analysis of the New-Hanbok brand website, the research was conducted through a survey of 355 women in their 20s and older. The survey consisted of 24 questions which were divided into pattern, color, material, and recognition type questions. The research results are as follows. First, most adult women answered that a New-Hanbok skirt is appropriate to wear at a holiday, anniversary, or outer dress for the spring and autumn seasons, and the design is the most important thing when considering buying. However, the ratios of wearing experience and possession were very low. Second, the preferred design aspects of a New-Hanbok skirt were the Jarak-skirt or Deot-skirt, calf-length, 5cm width of the waistband, 3cm uniform crease, a normal length waistband, bright neutral colors, and a waistband in different colors. For the double skirt, the design that shows 4cm of lining fabric and the different colors of upper fabric was the most preferred. The most preferred material was plain cotton. On the other hand, small floral patterns were preferred for patterned materials, and opaque upper fabric was most preferred for the double skirt. Through this study, it was confirmed that the Hanbok is seen as a positive aspect for modern consumers.

The purpose of this study is to investigate the change of students 'perception and expression about the motion of object following distance function $={x \atop 3}$ and distance function $y=\frac{x^3}{3}+3$ according to the necessity of research on students' perception and expression about integral constant. In this paper, we present the recognition and the expression of the difference of the constant in the relationship between the distance function and the speed function of the students, while examining the process of constructing the speed function and the inverse process of the distance function. This provides implications for the relationship between the derivative and the indefinite integral corresponding to the inverse process. In particular, in a teaching experiment, a constructive activity was performed to analyze the motion of two distance functions, where the student had a difference of the constant term. At this time, the students used the expression 'starting point' for the constants in the distance function, and the motion was interpreted by using the meaning. This can be seen as a unique 'students' mathematics' in the process of analyzing the motion of objects. These scenes, in introducing the notion of the relation between differential and indefinite integral, it is beyond the comprehension of the integral constant as a computational procedure, so that the learner can understand the meaning of the integral constant in relation to the motion of the object. It is expected that it will be a meaningful basic research on the relationship between differential and integral.

This study was designed to examine the degree of dependence on dietary environment, evaluate the perception of metal service program and investigate factors affecting the demand for meal service programs for elderly parents. The purpose of this study provided the basic information for the development and systemization of meal service program for elderly. Eight hundred twenty semen adults who have elderly parents were surveyed using pre-designed written questionnaire. According to the results on the life environments of their elderly parents, psychological factors(41.7%), living condition(14.3%) and dietary environment (13.2%) had trouble. Physical and psychological conditions significantly affected the dietary environment(p<0.05). Only 9.2% of the subjects were already aware of recognized the meal service program for elderly, and the degree of recognition differed significantly by sex and education level. Women had better perception of meal service program for elderly than men. In men, they would expect to use congregate meal service(44.1%), home-delivered meal service (23.7%), nursing home meal service(16.9%) in order. On the other hand, for women, home-delivered meal service (41.2%), congregate meat service(44.1%), and nursing home meal service (16.8%) in order. Therefore there are significant differences between men and women what type they want(p<0.001). For those who haute both of the parents or either one of them, they would use more of congregate meal service (38.8%) and home-delivered meal service (38.8%) than nursing home meal service (15.5%). The group whose parents are lower socio-economic status would have tendency to use the nursing home meal service (p=0.06). The group of whom believe the dietary environment is the problem of their parents'life environment had preference of using congregate meal service and home-delivered meal service.
