In come cases, people differently respond on the same joke or thoughtless behavior - sometimes like it and laugh, another time feel annoyed or angry. This fact is explained that experiences which we had in the past are remembered by emotional memory, so they cause different responses. When people face similar situation or feel similar emotion, they evoke the emotion experienced in the past and the emotional memory affects current emotion. This paper suggested the mechanism of the emotional memory using SOM through the similarity between the emotional memory and SOM learning algorithm. It was assumed that the mechanism of the emotional memory has also the characteristics of association memory, long-term memory and short-term memory in its process of remembering emotional experience, which are known as the characteristics of the process of remembering factual experience. And then these characteristics were applied. The mechanism of the emotional memory designed like this was applied to toy hammer game and I measured the change in the power of toy hammer caused by differently responding on the same stimulus. The mechanism of the emotional memory suggest in above is expected to apply to the fields of game, robot engineering, because the mechanism can express various emotions on the same stimulus.

시스템의 기능이 많아지면서 시스템의 반응시간은 중요한 요소로 인식되고 있다. 반응지연에 대한 기존의 연구들은 대부분 컴퓨터를 사용하는 상황을 바탕으로 이루어졌고 더 단순한 과제를 사용하는 기기를 바탕으로 이루어진 연구는 부족한 실정이다. 이에 본 연구는 휴대전화를 사용하는 상황에서 반응지연이 사용자들의 행동과 감정에 미치는 영향을 알아보고자 하였다(실험 1; 독립변인: 반응지연 정도, 종속변인: 행동적, 정서적 평가). 더 나아가 사용자가 제품을 사용하는 상황(활성화된 모드)에 따라 동일한 반응지연이 있을 경우 행동 및 감정 평가에서 차이가 나타나는지 알아보았다(실험 2; 독립변인: 반응지연 정도, 사용모드, 종속변인: 행동적, 정서적 평가, 스트레스, 정신적 노력). 그 결과, 반응지연이 있으면 과제를 수행하는 시간(효율성)이 길어지고 부정적인 감정이 유발됨을 알 수 있었다. 또한 상황(활성화된 사용 모드)에 따라서 동일한 과제를 수행하는 경우라도 그 평가에서 차이가 나타남을 알 수 있었다. 즉, 뚜렷한 목적을 가지고 과제를 했을 경우 반응지연이 있게 되면 그렇지 않은 경우보다 더 부정적인 감정을 느끼고 이 경우 반응지연의 유무가 큰 영향을 미친다는 결과가 나타났다. 또한 같은 과제를 수행함에 있어서도 정신적인 노력이 더 많이 소모된다고 느끼는 것으로 나타났다. 본 연구는 휴대전화 상황에서 반응지연 정도가 사용자들의 감정뿐 아니라 수행에도 영향을 줌을 확인하였고 동일한 과제의 제시한 경우라도 사용 환경에 따라 제품 평가에 차이를 보임을 실험을 통하여 확인하였다.

정서조절은 정서와 관련된 개인차 요인이 개인의 정서 생활 및 행동에 미치는 영향을 매개하는 것으로 알려져 있다. 본 연구는 기존 매개모델에 상황 요인을 추가하여 상황에 따라 정서조절의 매개효과가 변화하는지 알아보았다. 이를 위해 다양한 직종에서 고객응대를 주 업무로 하고 있는 180명의 감정노동자를 대상으로 설문을 실시하여 감정노동자의 일상적 부정정서, 인지적 재평가, 정서적 소진, 본인이 경험하는 고객 불만의 강도 등을 측정하였다. 조절된 매개효과를 알아보기 위하여 조건적 간접효과를 분석한 결과, 고객 불만의 강도가 높은 상황에서는 부정정서가 인지적 재평가를 매개로 하여 정서적 소진에 미치는 간접효과가 정적으로 유의하였으나 고객 불만의 강도가 낮은 상황에서는 해당 간접효과가 부적으로 유의하였다. 이는 높은 강도의 부정정서 유발 상황에서는 인지적 재평가의 매개효과를 통해 감정노동자의 정서적 소진이 감소될 수 있지만, 낮은 강도의 부정적서 유발 상황에서는 인지적 재평가의 매개효과를 통해 정서적 소진이 증가될 수도 있다는 것을 보여준다. 이러한 결과는 정서조절 연구에 있어 개인차적인 측면과 상황적 측면이 통합적으로 고려되어야 함을 강조하며, 감정노동자 직군의 정서적 특수성에 대한 정보를 제공한다.

This paper proposes an algorithm for risk situation recognition using facial expression. The proposed method recognitions the surprise and fear expression among human's various emotional expression for recognizing dangerous situation. The proposed method firstly extracts the facial region using Harr-like technique from input, detects eye region and lip region from the extracted face. And then, the method applies Uniform LBP to each region, detects facial expression, and recognizes dangerous situation. The proposed method is evaluated for MUCT database image and web cam input. The proposed method produces good results of facial expression and discriminates dangerous situation well and the average recognition rate is 91.05%.

본 논문은 얼굴의 표정 인식을 이용한 위험상황 인지 알고리즘을 제안한다. 제안방법은 인간의 다양한 감정 표정 중 위험상황을 인지하기 위한 표정인 놀람과 공포의 표정을 인식한다. 제안방법은 먼저 얼굴 영역을 추출하고 검출된 얼굴 영역으로부터 눈 영역과 입술 영역을 추출한다. 각 영역에 Uniform LBP 방법을 적용하여 표정을 판별하고 위험 상황을 인식한다. 제안방법은 Cohn-Kanade 데이터베이스 영상을 대상으로 성능을 평가하였다. 그 결과 표정 인식에 좋은 결과를 보였으며 이를 이용하여 위험상황을 잘 판별하였다.

The aim of this study was to estimate the effects of an early childhood environmental education program developed on the basis of relationships among preschoolers' knowledge, emotional attitude, and perceived behavior control of environmental pollution on their knowledge, emotional attitude, perceived behavior control, and behavioral intention. A total of 146 five-year-old preschoolers from eight child-care centers in Seoul and Kyoungki Province participated in this study. The following are the main results of this study. first, the higher the level of knowledge the preschoolers had, the more negative emotional attitude they displayed. Furthermore, the more negative emotional attitude they displayed, the higher the level of perceived behavior control they had. On the contrary, the relationships between knowledge and perceived behavior control varied with exposure situation to environmental pollution. Second, after the environmental education program was administered to the experimental group, the preschoolers from experimental group exhibited more knowledge, more negative emotional attitude, higher perceived behavior control and more active behavioral intention towards environmental pollution than those in the control group.

The purposes of this study were to investigate (1) intention perspective taking, (2) cognitive cuing according to infant age, cue type, and emotional-situation fit, and (3) the relationship between a child's intention perspective taking and cognitive cuing. The subjects were 2 groups of 41 infants each aged 3- and S-years-old from two different day-care centers in Seoul and Kyonggi province. Each child was individually interviewed with pictorial tasks. There were significant differences in the children's intention perspective taking according to their age, type of intention, and intention-outcome fit. There were also significant differences in the children's cognitive cuing according to their age, cue type, and emotional-situation fit. A relationship between the intention perspective taking and cognitive cuing was also revealed that is, the thinking and application responses of cognitive cuing were positively related to the children's intention perspective taking.

The purpose of this study is to develop and evaluate a social competence enrichment program for institutionalized children in early childhood. The program was developed to enhance institutionalized children's social competence. The program consists of sixteen 30-minute sessions. 19 institutionalized children (11 boys and 8 girls) participated in this program. The effect of this program was evaluated by institutionalized preschool children's emotional knowledge and interpersonal problem solving strategy. Assessment of emotional knowledge consists of identification and situation task. Interpersonal problem solving strategy includes forceful, prosocial, and manipulative strategy. Results showed that there was a significant experimental effect for emotional knowledge. Experimental children showed higher scores of emotional knowledge than control children. Also, there was a significant experimental effect for prosocial and forceful strategy. Experimental children showed higher ratio of prosocial strategy and lower ratio of forceful strategy than control children. The results of program evaluation revealed that this program was helpful for promoting institutionalized children's social competence.

Objectives : The rapidly changing consumer-centric and customer-oriented nature of the medical environment results in significant cognitive load. We aimed to clarify the situation of emotional labor and job stress among hospital employees and seek policies and hospital management for employees' emotions. Methods : The study was conducted through a questionnaire about emotional labor and job stress among 554 individuals working in Seoul, in 9 national, public, and private hospitals. Results : The results of the emotional labor and job stress questionnaire showed statistically significant differences in surface behavior and job stress; both had higher values in employees from the private hospitals than employees from public hospitals. Conclusions : This study found that the stress of emotional labor is a serious problem in government medical institutions. In addition, these institutions need to provide internal customer satisfaction through the hospital ombudsman and harmonize work and healing programs by including plans for improvement.
