In this paper, we deal with an emotion recognition method using facial images and speech signal. Six basic human emotions including happiness, sadness, anger, surprise, fear and dislike are investigated. Emotion recognition using the facial expression is performed by using a multi-resolution analysis based on the discrete wavelet transform. And then, the feature vectors are extracted from the linear discriminant analysis method. On the other hand, the emotion recognition from speech signal method has a structure of performing the recognition algorithm independently for each wavelet subband and then the final recognition is obtained from a multi-decision making scheme.

Modern day people can easily use an e-mail client for general communication, because of using Internet and cellular phone. The mail client for the purpose of private and business affair, advertisement, news searching, and business letter is widely used and has side effects. People could send an important document via an electronic mail client. It is important to support an e-mail client intelligent. We think that many kinds of techniques of natural language processing must be provided in the client with human's emotion. We consider to design a new mail client with six kinds of senders' emotional information; delight, angry, sad feeling and message to express, manner of talking, a discomfort index etc. Before sending an e-mail, we suggest a user to correct a bad word because we do not want to feel bad to a receiver. We present a proper process of sending/receiving for users with a new designed e-mail clients.

최근의 정보보호 관련 사고를 살펴보면 기업 내부자로 인한 개인정보의 유출과 같이 특별한 기술 없이 이루어지는 인간 중심의 정보보호가 이슈화되고 있다. 그만큼 점점 사회공학적인 위협이 증가하고 있는 추세이며, 그 위험성이 사회 전반적으로 인식되어가고 있다. 본 지를 통해 사회공학의 의미에 대해 되짚어보고, 사회공학 라이프 사이클과 최근의 사회공학 공격 기법에 대해 분석한다. 또한 일반적 사회공학 의미인 인간 상호 작용의 깊은 신뢰를 바탕으로 사람들을 속여서 보안 절차를 우회하는 등의 기존 개념에 더하여 유사한 사례를 바탕으로 인간의 대표적 감정 상태(두려움, 슬픔, 기쁨)를 이용한 사회공학 기법에 대해 논한다.

본 논문은 분노, 행복, 평정, 슬픔, 놀람 둥과 같은 인간의 감정상태를 인식하는 새로운 접근에 대해 설명한다. 이러한 시도는 이산길이를 포함하는 연속 은닉 마르코프 모델(HMM)을 사용함으로써 이루어진다. 이를 위해, 우선 입력음성신호로부터 감정의 특징 파라메타를 정의 한다. 본 연구에서는 피치 신호, 에너지, 그리고 각각의 미분계수 등의 운율 파라메타를 사용하고, HMM으로 훈련과정을 거친다. 또한, 화자적응을 위해서 최대 사후확률(MAP) 추정에 기초한 감정 모델이 이용된다. 실험 결과, 음성에서의 감정 인식률은 적응 샘플수의 증가에 따라 점차적으로 증가함을 보여준다.

대화 시스템에서 사용자 발화에 대한 감정 분석은 적절한 시스템 응답과 서비스를 제공하는데 있어 매우 중요한 정보이다. 본 연구에서는 단순한 긍, 부정이 아닌 분노, 슬픔, 공포, 기쁨 등 Plutchick의 8 분류 체계에 해당하는 상세한 감정을 분석 하는 데 있어, 임베딩 모델을 사용하여 기존의 어휘 자질을 효과적으로 사용할 수 있는 새로운 방법을 제안한다. 또한 대화 속에서 발생한 감정의 지속성을 반영하기 위하여 문장 임베딩 벡터와 문맥 임베딩 벡터를 자질로서 이용하는 방법에 대해 제안한다. 실험 결과 제안하는 임베딩 자질은 특히 내용어에 대해 기존의 어휘 자질을 대체할 수 있으며, 데이터 부족 문제를 다소 해소하여 성능 향상에 도움이 되는 것으로 나타났다.

본 논문에서는 효과적인 정보를 표현하는 ICA(Independent Component Analysis)-Factorial 표현 방법을 이용하여 얼굴감정인식을 수행한다. 얼굴감정인식은 두 단계인 특징추출과 인식단계에 의해 이루어진다. 먼저 특징추출방법은 PCA(Principal Component Analysis)을 이용하여 얼굴영상의 고차원 공간을 저차원 특징공간으로 변환한 후 ICA-factorial 표현방법을 통해 좀 더 효과적으로 특징벡터를 추출한다. 인식단계는 최소거리 분류방법인 유클리디안 거리를 이용하여 얼굴감정을 인식한다. 이 방법의 유용성을 설명하기 위해 6개의 기본감정(행복, 슬픔, 화남, 놀람, 공포, 혐오)에 대해 얼굴데이터베이스를 구축하고, 기존의 방법인 Eigenfaces, Fishefaces와 비교하여 좋은 인식성능을 보이고자 한다.

This study aims to study the codes that can code the Sijo's emotional codes into AI and use them in literature therapy. In this study, we conducted emotional coding of the Sijo Crying Cuckoo at the Empty Mountain. As a result, the Emotion Codon was able to indicate the state of sadness catharsis. This implanting of the Sijo's emotional codes into Emotion Codon is like implanting human emotions into AI. If the basic emotion codes are implanted in the Emotion Codon and induced of AI's self-learning, We think AI can combine various emotions that occur in the human body. AI can then replace human emotions, which can be useful in treating of human emotions. It is believed that continuing this study will induce human emotions to heal the mind and spirit.

Purpose: The purpose of this qualitative study was to explore how adolescent survivors of childhood cancer grieve the death of cancer peers. Methods: Data were obtained from Korean adolescents with cancer between the ages of 13 and 18 (N=12) through semi-structured interviews (face-to-face, telephone, and Internet chatting), observations of the social dynamics of participants in self-help groups, and retrieval of personal Web journals. Based on the grounded theory methodology, data collection and analysis were conducted simultaneously, and constant comparative methods were used. Clarke's situational analysis was adopted, and this paper focused on presenting "how to" and "what we can learn" from this analytic strategy. Results: Mapping examples were visualized using of three modes of maps. Adolescent cancer survivors coped with reminders of the "darkness" that ultimately featured their overall grief. Additionally, adolescents' encounters and avoidance of grief were triggered by introspection and interactions with family and friends. Conclusion: Situational analysis provided an efficient way to analyze the experiences of adolescent survivors of childhood cancer by systematizing possible information within the relational social contexts of the research phenomenon.

Cho Gwang-jo(趙光祖, 1482-1519) was the moralist who had the purest conscience and aimed the devoted politics among many fellow Confucianists of Chosun Dynasty. He even criticized his teacher who was in his late forty years for not being able to control his emotions when he was just a teenager. That is to say, he was the one who have kept his cold reasons for entire life. Nevertheless, as mentioned before, Cho Gwang-jo was very faithful to his emotions and also very honest. We find that he was definitely emotional. He demanded to change the relationship between the king and the courtier to the one between the father and the son with humane communication. He expressed his mind and emotion he had used to have at the moment of his death: he loved his king just as he loved his father. However, the king, Joongjong, was indifferent at the human's emotion as if he was a senseless figure. That was the saddest frustration and grief he had. However, his grief did not remained just as the mere grief but again survived as the hope for the survivors and descendants with the big echo. In this respect, his gried did not just end as the grief but it can be said that it even revived itself as the strength and courage. Then, Cho Gwang-jo's life as a human being was never a failure. Moreover, his grief and agony did not just remained as the vain emotion and sadness.

In this paper, an emotion recognition method using speech signal is presented. Six basic human emotions including happiness, sadness, anger, surprise, fear and dislike are investigated. The proposed recognizer have each codebook constructed by using the wavelet transform for the emotional state. Here, we first verify the emotional state at each filterbank and then the final recognition is obtained from a multi-decision method scheme. The database consists of 360 emotional utterances from twenty person who talk a sentence three times for six emotional states. The proposed method showed more 5% improvement of the recognition rate than previous works.
