This paper presents the analysis of the human driving behavior based on the expression as a GMDH technique focusing on the driver's collision avoidance maneuver. The driving data are collected by using the three dimensional driving simulator based on CAVE, which provides stereoscopic immersive vision. A GMDH is also introduced and applied to the measured data in order to build a mathematical model of driving behavior. From the obtained model, it is found that the longitudinal distance between cars($x_1$), the longitudinal relative velocity($x_2$) and the lateral displacement between cars($x_4$) play important roles in the collision avoidance maneuver under the 3D environments.

Purpose: To investigate the effect of a mother's modeling and feeding practices on the eating behavior of the children. Methods: From April to June 2018, 1,036 young children aged 2 to 6 years and their mothers in Gyeongsan, Gyeongsangbuk-do, were examined for their eating behavior and feeding practices using a verified dietary behavior test (DBT). The children's dietary behavior was classified into four categories: "access evasiveness", "sensory acuity", "hyperactivity", and "irregularity". The mother's eating behavior was classified into three categories: "pickiness", "negligence", and "irregularity", and feeding practice types were classified into two categories: "responsibility/monitoring", and "restriction/pressure". The differences between the groups were tested using the t-test, ANOVA, and Duncan's multiple range test. The influence of feeding practices on the children's eating behavior was analyzed by hierarchical regression analysis while controlling for the mother's modeling. Results: The problem rates of irregularity, negligence and pickiness in the mother's modeling were 33.7%, 22.8%, and 20.7%, respectively. An analysis of the mother's feeding practices revealed that responsibility/monitoring had a middle, high and low significance in 74.2%, 17.3%, and 8.5% of respondents, respectively and the risk rate of restriction/pressure when guiding children to eat was 15.3%. The problem rates for sensory acuity, access evasiveness, irregularity, and hyperactivity in children were 27.9%, 26.1%, 24.8%, and 22.0%, respectively. Among the four eating behavior characteristics of children, the child's access evasiveness and sensory acuity were more affected by their pickiness rather than the mother's feeding practices, and the child's hyperactivity was more influenced by feeding practices than the mother's eating behavior. The child's irregularity was similarly affected by the mother's eating behavior and feeding practices. Conclusion: Since the mother's eating behavior and feeding practices affect the children's eating behavior, a diet improvement program for children should consider not only the nutrition education of children but also the mother's eating behavior and provide the necessary intervention for feeding practices.

This study was carried out to examine the drift of Gammarus sobaegensis by acid stress as pH depression in Oweol creek from April 1996 to October 1996. The behavioral drifting was revealed to the characteristics of G. sobaegensis that is tend to increase as acid stress. And, tolerance level of G. sobaegensis to pH depression was different among the size classes. Individuals belong to small to medium size classes were weak in lower pH. Pattern of response in G. sobaegensis has a lower tolerance to acid stress at below pH 4.0 than above pH 5.0 in the artificial channel and show the possibility as an effective aquatic ecotoxicity test organism. The result of analysis of variance, water temperature (F-ratio : 66.596, p< 0.0005) and the size classes (F-ratio : 71.386, p< 0.0005) except pH level (F-ratio : 353.415, p<0.0005) were showed to the major factor for drift behavior by acid depression.

Online firms collect consumers' private information, which serves as a valuable database for marketing activities. In order to encourage consumers to provide their private information, online firms offer high quality websites for consumers who provide private information. However, identity theft, phishing, and pharming, become critical social issues, consumers started to avoid providing their private information to online firms. Thus, consumers often provide false or limited information, which lacks value for practical use for the online firms. The main issue raised in this study is to discuss how online marketing activities has influence on consumers attitude and information providing behavior. From the result, this paper found that websites reputation had greatest impact on willingness of providing information. Also this study revealed that unauthorized use is the key factor for increasing distrust and avoidance of providing information.

본 논문은 이동로봇의 다양한 작업들 중에 선행하는 물체를 안정하게 추종하는 동작중 예기치 못한 움직이는 장애물의 효과적인 회피 방법을 고려한다. 센서 기반의 이동로보트에서는 이동물체 추종과 충돌회피를 센서정보에 의존해서 해결해야 하는데 동일한 센서 정보로 추종물체와 충돌물체를 구분하는 것이 쉽지 않은 문제이다. 또한 명확히 규정되지 않은 환경에서 적용하기 어렵다. 따라서 본 논문에서는 이와 같이 명확히 규정되지 않은 환경에서 선행물체의 안정한 추종과 추종 중에 마주치는 이동 장애물에 대한 충돌회피를 위하여 이동로봇의 상태 판단에 따라 구분된 행동 선택 모드를 제안하고 실험적으로 확인한다.

This study explored the influence of conflict management styles (i.e., Integrating, Considering, Compromising, Dominating, Avoiding) adopted by early childhood teachers to deal with conflict that may arise with parents on parents' behavioral intentions (i.e., re-registration intentions, oral transmission intentions) with the mediating role of parents' trust in teacher on the relationship between conflict management styles and parents' behavioral intentions. The data were collected from 356 parents in southern Gyung-gi-do and data analysis was done through structural equation modeling using AMOS 26.0. The study results show that the Integrating style of teachers was positively related to the parents' intention of re-registration. Trust in teacher was found to have an mediation effect on the Integrating, the Avoiding and the Compromising styles and re-registration intentions and oral transmission intentions of parents respectively. The results imply the importance of conflict management styles and building trust for enhancing the parents' behavioral intentions.

This study explores the relationship between indirect contacts of older adults and ageism related behaviors by investigating adults' exposure to portrayals of older people and their images in media. This study also investigates how indirect contacts of older adults influence ageism related behaviors such as avoidance and discrimination against older adults through attitudes and social norms about older adults. Using an online survey collected from 252 adults aged 18-64 years, the authors found that indirect contacts of older adults through media predicted attitude toward older adults as well as social norms. The results also revealed that social norm predicted both avoidance and discrimination behavior against older adults while attitude toward older adults only predicted avoidance behavior. Finally, the findings indicated that attitude toward older adults mediated the relationship between indirect contacts through media and avoidance behavior. However, social norm mediated the relationships between indirect contacts through media and discrimination as well as avoidance behaviors. Implication and limitation of the findings are discussed.

This study explores and examines the impacts of the cultural characters on the brand attitude of Chinese regional consumers. This study used the 1,500 sample sized data collected from three major cities: Beijing, Shanghai and Guangzhou. We investigate that power distance, individualism/collectivism, uncertainty avoidance and long-orientation are statistically different across cities. The empirical studies show that individualism/collectivism and uncertainty avoidance have significant impacts on the brand attitude of Chinese regional consumers. We tested that the relationship between the brand power and the brand attitude is moderated by individualism/collectivism, the results indicate that the effect of the brand power on the brand attitude is moderated by uncertainty avoidance. These results imply that Chinese consumers' culture character of individualism/collectivism and uncertainty avoidance moderate their brand attitude. Based on this results, We suggested some implications for further market segmentation strategy, brand marketing strategy, and Chinese regional consumer culture research.
