  • In this paper, behaviors performing controls of a mobile robots are designed based on the concept of closed-loop controls. A control architecture, in which the behaviors coordinate concurrently with one others to achieve a task is also proposed. In the control architecture, task manager allocates valid resources and configures the weight of the behavior outputs to achieve the task. For practical implementation, a rate modulation strategy based on RMS(Rate Modulation Strategy) is proposed for efficient resource allocations. The rate modulation strategy is performed with considering control stability. The efficiency of the proposed rate modulation strategy is validated through simulation tests.

  • Obesity is a worldwide epidemic problem. The downward trend of an obesity onset age calls for research efforts on how to develop useful nutrition educational programs for children to maintain adequate body weight. Understanding the roles of objective and subjective body status in obesity-related attitudes, knowledge, and behaviors can provide important information. The current study aimed to examine obesity-related attitudes and knowledge and practices of eating behavior guidelines in relation to obesity and body shape satisfaction among children. The gender effect in the relations was also investigated. A self-administered survey was conducted with 260 fifth grade children at 2 public elementary schools in the suburbs of Seoul. Information on demographics, body size, body satisfaction, obesity-related attitudes and knowledge, and eating behaviors was collected. Study findings from one-way analysis of variance tests indicated no differences in mean scores of the attitudes, knowledge, and eating behaviors across the levels of obesity for both gender. The levels of body shape satisfaction was, however, found to be significantly related with the attitudes and eating behaviors in girls, while no such relation was seen in boys. Girls with lower body shape dissatisfaction had significantly more negative attitudes toward obesity which was not translated into practice of healthy eating behaviors. That is, contrary to general expectation, the level of practicing the eating behavior guidelines was significantly lower in those girls. While underlying reasons for this observation is not fully answered, gender-specific, body satisfaction-stratified, and behavior-focused approach in designing obesity prevention programs for elementary school girls is suggested efficient and useful.

  • 본 논문에서는 사용자 시스템이 악성 프로그램에 의해 피해를 입은 후 시그니처나 보안 패치가 나오기 전에 피해를 최소화하기 위한 방법으로 파일 DNA 기반의 행위 패턴 분석을 통한 탐지 기법을 연구하였다. 기존의 네트워크 기반의 패킷 탐지기법과 프로세스 기반 탐지 기법의 단점을 보완하여 제로데이 공격을 방어하고 오탐지를 최소화하기 위해 파일 DNA 기반 탐지기법을 적용하였다. 파일 DNA 기반 탐지기법은 악성코드의 비정상 행위를 네트워크 관련 행위와 프로세스 관련 행위로 나누어 정의하였다. 사용자 시스템에서 작동되는 프로세스의 중요한 행위와 네트워크 행위를 정해진 조건에 의해 검사 및 차단하며, 프로세스 행위, 네트워크 행위들이 조합된 파일 DNA를 기반하여 악성코드의 행위 패턴의 유사도를 분석하여 위험경고 및 차단을 통한 대응 기법을 연구하였다.

  • Purpose - The purpose of this study is to investigate the relationship among narcissism, usage motives, usage behaviors, satisfaction with and continuance intention to use fashion social media. Research design, data, methodology - A questionnaire survey was used to collect data after conducting a pilot test. Based on the reliability test of the preliminary questionnaire used for the pilot test, the questionnaire was revised. The final questionnaires were administered to 238 fashion social media users and 216 were used for the data analysis. To assess the validity of these measures, exploratory factor analysis and the confirmatory factor analysis were performed. Structural equation modeling analysis were employed for data analysis. Results - Five factors of the usage motivation of fashion social media were extracted: information-seeking, relationship-seeking, practicality-seeking, enjoyment-seeking and self-expression motives. The statistical analysis confirmed the influence of the narcissism tendency on all of the usage motives of fashion social media, three of the fashion social media usage motives influencing information diffusion behavior, and the influence of the information diffusion behavior on users' satisfaction and continuance intention to use fashion social media. Narcissism exerted the highest influences on self-expression motive followed by information-seeking, enjoyment-seeking, relationship-seeking and practicality-seeking motives in order. Factors affecting fashion information diffusion behaviors are practicality-seeking motive, self-expression motive, and relationship-seeking motive. The greater the diffusion of information, the higher the satisfaction with using fashion social media. The consumers with higher satisfaction intended to use fashion social media and share information more frequently. Conclusions - The results indicate that narcissism is an important factor in fashion social media usage motivation. The main motives for narcissistic people to spread information is for the practical purpose at the most, and then to express their personality and style, and to build relationship with others. The satisfaction through active information sharing behaviors seems to play a key role to lead high continuance intention of fashion social media. These implies that marketing strategies to satisfy consumers' narcissism and motives to use social media, and to stimulate the information diffusion behaviors can be used to meet their needs for higher satisfaction with fashion social media.

  • Children's sex, temperament, and empathy were studied as antecedents of preschoolers' prosocial development. Eighty eight 5-, and 6-year-old children, 41 boys and 47 girls, were sampled in two kindergartens. Children's naturally occurring prosocial behaviors were videotaped in their classrooms for 21 minutes in 3 days. Teachers rated the children's prosocial tendency using a questionnaire. Empathy was measured individually with a picture/story measure, and mothers provided information on children's temperament using a questionnaire. The two measures of preschoolers' prosocial behaviors, teacher ratings and free play observations, were moderately related. Girls were more prosocial in terms of helping/sharing/cooperation in both teacher-ratings and free-play observations. Preschoolers' adjustability was moderately related to the prosocial behaviors of children in both teacher-ratings and observations. Boys' verbal empathy was related to the observed prosocial behaviors.
