In this paper, we propose a psychological state estimation process that computes children's attention and tension in response to training stimuli. Joint attention was adopted as the training stimulus required for behavioral intervention, and the Discrete trial training (DTT) technique was applied as the training protocol. Three types of training stimulation contents are composed to check the user's attention and tension level and provided mounted on a character-shaped tabletop robot. Then, the gaze response to the user's training stimulus is estimated with the vision-based head pose recognition and geometrical calculation model, and the nervous system response is analyzed using the PPG and GSR bio-signals using heart rate variability(HRV) and histogram techniques. Through experiments using robots, it was confirmed that the psychological response of users to training contents on joint attention could be quantified.

제조물 책임법(PL： Product Liability) 시행을 앞두고, 최근 고객 및 기업에 주목을 받고 있는 제도가 리콜제도이다. 본 연구에서는 고객 보호측면에서 국내에서 시행중인 리콜제도에 대한 고객반응을 연구하여 장차 시행될 PL에 대한 대응방향을 제시하고자 한다. 기존의 연구에서는 리콜에 대한 고객의 반응을 알아보기 위한 방법으로 경쟁을 고려하자 않은 리콜 시나리오를 구성하여 기존과 잠재고객의 반응을 파악하였다. 본 연구에서는 리콜 관련 신문보도 이후 고객의 반응을 알아보고자 경쟁관계에 있는 국내 2개 자동차사의 브랜드에 대한 상대적인지도, 리콜 정보에 대한 상대적 심각도, 그리고 각 기업의 리콜대응에 대한 고객 만족도 등이 향후 신규구매 및 재구매에 미치는 영향을 분석하고자 로지스틱 모형을 이용하였다. 그 결과, 향후 재구매시는 기업의 상대적 사회적인지도, 리콜정보에 대한 상대적 심각도 등이 유의한 영향을 미치는 것으로 나타났다. 이에 반해 신규 구매시는 향후 구매하고자 하는 제조기업과 구매시 고려하는 상품정보가 관련성이 있는 것으로 파악되었다.

현재 수요반응(Demand Response) 프로그램은 발전설비 용량의 부족이나 높은 발전 연료비용의 상승으로 인해 다양한 나라들에서 도입되고 있는 실정이다. 그것은 실시간으로 소비자들이 그들의 소비패턴을 선택할 수 있는 프로그램이라 말할 수 있다. 다시 말하면, 수요반응이란 소비자들의 일반적인 전력소비패턴에서 전력가격이나 기타 다른 신호에 반응하여 전력 사용량을 변화시키는 것으로 정의할 수 있다. 수요반응의 효과는 전력가격의 급상승 방지, 공급 신뢰도 향상, 그로 인한 사회적인 복지향상 등 여러 가지 측면에서 생각해 볼 수 있다. 이러한 다양한 효과 가운데, 본 논문에서는 thermal comfort zone을 고려하여 수요반응 프로그램을 수행하는 동안 전력판매사업자 입장에서 최대의 이득을 얻기 위한 적정 인센티브와 부하 감축량을 결정한다.

The purposes of the study is builded upon previous researches to investigate the relationship among store's physical environment, customers' emotional responses and behavior intention. For achieving study purposes, research model and hypotheses were set up after reviewing previous researches. The data were collected from a sample of 659 consumers of korea and china department stores, then used to conduct an empirical analysis. The results showed: First, the significant relationship were partially found among store's physical environment, emotional responses and behavior intention, design factor, social factor of store' physical environment both influence shoppers' positive emotions, indirectly influence shoppers' behavior intention through positive emotions, and social factor influence shoppers' negative emotions, indirectly influence shoppers' behavior intention through negative emotions. Second, the results also showed that they are different between korea and the china customer. Therefor, this study has provided a variety of theoretical and practical implications for global retailers to set up marketing strategies.

There are an increasing emphasis on affective domain, for example interest or belief, in science education. But decreasing interest on learning science and tendency to avoid science-related job are serious problems of secondary science education, especially in case of vocational high school students. However there are few researches for vocational high school students. In this study, preference for science is assumed to be a multidimensional property that reveals ones' behavioral volition and valuation as well as emotional response upon learning science. To investigate vocational high school students' preference for science and its causal factors, a Likert style questionnaire was developed through factor analysis. Students' preference for science was analyzed by 3 categories, and its causal factors are investigated by path analysis using structural equation model.

The aim of this study was to know the experience of emergency nurses on hospital violence and violence's effect on nurses via convergent approach of phenomenological methodology to be known for a good method to study alive human's experience. This study is a qualitative study converged the phenomenological methods and 5 emergency nurses participated in an in-depth interview. From the transcript, 41 significant statements, 17 clusters of theme, 6 categories were extracted. The extracted categories are violence's background, emotional response, physical response, social response, passive coping and active coping. The hospital violence's negative effect on emergency nurses occurred in various sides and the countermeasure is required to prevent violence from hospital setting anymore.

This study analyzed some of the discrepancies in quantitative and qualitative data focusing on cognitive and affective achievement in science education. Academic and affective achievement score of 308 high school students were collected as quantitative data, and 33 students were interviewed for qualitative data. We examined the causes and types of discrepancies in terms of testing tools. As a result from quantitative data, there were a large number of students with a big difference between subjects in cognitive achievement, and constructs in affective achievement. More than 20% of the students did not match tendency between achievements in two areas. Through interviews, some examples such as intentional control of science learning for future study and careers, different responses by differences in perception between school science and science, appeared. A comparison of quantitative data by testing tool between qualitative ones and interviews showed conflicting result, where most students evaluated themselves differently from their own quantitative data. That is due to the students' interaction with the testing tools. Two types of discrepancy related to testing tool are found. One is 'the concept difference between the item developer and students,' the other is 'the difference between students' exposed response and their real mindset.' These are related to the ambiguity of the terms used in the tool and response bias due to various causes. Based on this study, an effort is required to elaborate the testing item that matches students' actual perception and to apply students' science learning experience to testing items.

자연적인 서식지에서 토끼는 번번히 육식 동물의 먹이가 된다. 이들의 일차적이고 우선적인 생존 반응은 발견을 피하기 위한 노력으로 조용히 있는 것이다. 토끼는 폭발적인 속도를 빠르게 낼 수 있고 짧은 거리에서 즉시 방향을 바꿀 수 있도록 가벼운 뼈, 작은 앞다리, 강력하고 잘 발달된 뒷다리를 가졌을 뿐만 아니라, 예민한 청각과 즉각적인 후각을 발달시킴으로써 'fight or flight(적자생존)'로 적응해왔다. 이런 생존 반응은 욕구가 없어진 것으로 나타나는 대부분의 집토끼에도 여전히 존재하지만, 이런 토끼들은 장애에 대해 반응이 불완전하고 변화에 쉽게 스트레스를 받는다. 스트레스를 받은 동물은 일차적으로 anorexia와 용변의 빈도와 일관성에 변화를 유발하는 건강, 생식, 행동적인 문제에 더욱 민감하다.

특정 환경이 제시하는 이미지는 색으로 나타내어진다. 그러면, 특정 사회적 환경을 생각할 때 사람들은 특정한 색채 반응으로 그것에 맞추려고 하는가\ulcorner 본 연구에서는 특정 상황에 따라 사람들이 다르게 표현하는 색채이미지를 파악하여, 각각의 사회적 상황에 맞는 색채 코디네이션과 이미지에 맞는 색채 감성 제품을 디자인하는 가능성을 제안하고자 한다. 색채와 관련된 대표적인 제품이 화장품이다. 화장품에서 사용되는 색감은 사용자의 취향과 같은 성격특성에 따라 달라지지만, 이것은 또한 사회적 상황에 따라 다르게 표현되기도 한다. 본 연구에서는 사회적 상황을 캐주얼, 비즈니스, 지적분위기, 이브닝(섹스어필)의 4가지 조건을 제시하고 이것에 따른 색채 감성 이미지가 어떻게 나타나는지를 살펴보았다. 연구결과는 각각의 상황은 일관적인 색채 이미지를 가지고 있을 뿐 아니라, 사람들에게 공통적으로 적용될 수 있는 색채이미지로 표현된다는 것을 밝힐 수 있었다. 특정 환경에 관한 기대는 특징적인 색채이미지로 반영되며, 이런 결과들은 환경색채의 디자인과 구체적인 상황과 맞는 제품의 색조 디자인 등에 직접 활용될 수 있을 것이다.

Nowadays, as many robots are developed for desktop, users interact with the robots based on speech. However, due to technical limitations related to speech-based interaction, an alternative is needed. We designed this research to design a robot that interacts with the user by using unconditional reflection of biological signals. In order to apply bio-signals to robots more effectively, we evaluated the robots' overall service evaluation, perceived intelligence, appropriateness, trustworthy, and sociability according to the degree of the robot's embodiment level and the response speed of the robot. The result showed that in terms of intelligence and appropriateness, 3D robot with higher embodiment level was more positively evaluated than 2D robot with lower embodiment level. Also, the robot with faster response rate was evaluated more favorably in overall service evaluation, intelligence, appropriateness, trustworthy, and sociability than the robot with slower response rate. In addition, in service evaluation, trustworthy, and sociability, there were interaction effects according to the robot's embodiment level and the response speed.
