Recently, negative emotional responses by drivers are a growing problem, which leads to not only a traffic accident but a crime so called 'road rage' in countries with heavy traffics including South Korea. Under such a circumstance, measuring stress- and fatigue-induced emotional responses by means of wireless communication and a wearable system would be useful. The purpose of this study is to implement a system that measures various signals from a driver, derives and monitors his emotional responses from the measurements and verify its derivations with reliability. This paper, as a first part of the research, describes how the system has been implemented with experimental methods.

The purpose of this study was to investigate factors such as self-esteem, depression, anger expression and social support that affect the health promoting lifestyle in middle-aged women. Number of middle-aged women participated in the survey were 150. Data were collected by means of self reported questionnaires from 1. September to 30. November 2011 and analyzed by using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients and multiple regression with SPSS windows version 17.0. There were statistically significant differences in the health promoting lifestyle according to the frequency of physical activities, frequency of hobbies or social activities and menstruation state. There were significant positive correlations between health promoting lifestyle and self-esteem, anger-control and social support. Negative correlations were found between health promoting lifestyle and depression, anger-in and anger-out. Self-esteem, social support, frequency of physical activities and frequency of hobbies or social activities were predictors of a health promoting lifestyle. Nurses should focus on factors identified in this study when developing nursing interventions to improve a health promoting lifestyle for middle-aged women.

The purpose of this study is to examine the relationship between stress symptoms and health-promoting behaviors (HPB) among two residence groups of university students. Data were collected by questionnaires from 313 students living in a dormitory and 281 students not living in a dormitory. Data were collected from October 21 to November 20, 2015. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression. Dormitory residents presented higher HPB scores among both genders. For dormitory residents, smoking and drinking affected the HPB, and for non-dormitory residents, scholastic achievement and health status affected the HPB significantly. HPB had significantly negative correlations with depression, anxiety, and anger for dormitory residents and with cognitive disorganization, depression, and anger for non-dormitory residents. The results of multiple regression analysis show that the significant factors for dormitory students in order of importance were depression, anger, and anxiety, and the variance was 67%. For non-dormitory students, the significant factors were depression and anger with a variance of 63%. The results suggest that it is necessary to develop a suitable HPB program for university students.

This study describes an emotion classification method using two different feature parameters of four-channel EEG signals. One of the parameters is linear prediction coefficients based on AR modelling. Another one is cross-correlation coefficients on frequencies of ${\theta}$, ${\alpha}$, ${\beta}$ bands of FFT spectra. Using the linear predictor coefficients and the cross-correlation coefficients of frequencies, the emotion classification test for four emotions, such as anger, sad, joy, and relaxation is performed with an artificial neural network. The results of the two parameters showed that the linear prediction coefficients have produced the better results for emotion classification than the cross-correlation coefficients of FFT spectra.

이 연구의 목적은 IAPS(국제정저사진체계) 사진자극에 의해 유발된 각각의 주관적 정서상태에 특정적인 자율신경계 반응이 존재하는지를 규명하는 것이다. 부정적 정서(분노, 슬픔, 놀람)와 긍정적 정서(행복, 흥분)를 유발하는 IAPS사진을 각 60초 동안 제시하였을 때 유발되는 심박률, 호흡률, 피부전도반응을 측정하였다. 시각자극이 주어진 초리 30초 동안 통계적으로 유의미한 심박률 감속 및 호흡률 감소를 보여주었으며, 뚜렷한 피부전도반응이 출현하였다. 심박률 감속은 혐오보다 흥분에서 더 크게 나타났고, 피부전도반응의 진폭은 혐오보다 흥분에서 더 큰 것으로 나타났다. 한편, 피부전도반응의 진폭이 상승하는 시간은 슬픔, 행복, 놀람보다 혐오에서 더 짧아지는 경향을 보여주었다. 이와 같은 자율신경계 반응(심박률, 호흡률, 피부전도반응)은 정서상태간에 뚜렷한 차이를 보여주며, 특정 정서상태에서 자율신경계 반응은 개인차가 있기는 하지만 전체적으로 매우 전형적인 반응패턴을 보여주었다. 본 연구의 결과는 정서 특정적인 자율신경계 반응이 존재할 가능성을 시사해주며, 생리신호분석을 통해서 심리적 정서를 결정할 수 있는 형판(template)의 구성을 위해서 다양한 자율신경계 정서반응의 지표를 포괄적으로 측정 분석하는 후속연구가 요구된다.

The purpose of this study was to identify the impact of the mood state on the quality of life (QOL) of the female breast cancer survivor. The study was cross-sectional survey. This study was conducted from September 10th to September 20th, 2013. The subjects were 120 breast cancer survivors in Seoul city in Korea. The obtained data were analyzed by SPSS/WIN 21.0 program. The mean score of mood state was 39.20 and the mean score of the quality of life was 83.59. The levels of mood state and the quality of life were negatively correlated. The significant factors influencing quality of life were vigor and anger of the mood state, religion that explained 39.1% of the variance. The results suggests that appropriate support service should be provided to improve the quality of life after nurses evaluate breast cancer survivor's mood states and identify the symptoms of mood disturbances.

People generally think that negative effects of violent game contents are more serious in active playing behavior than passive watching video. This research examined the negative emotions which could arise out of playing violent games as fear, anxiety, hate, state-anger, hostility, and depression and performed an experiment methodology to assess those emotion effects between playing and watching violent game. The results of this research found that the watching group of violent video game showed a stronger internal negative feeling such as hate and depression, but the playing group of violent game had a deeper state-anger and hostility as external negative feeling than watching group. This research concludes that each media delivers different negative feelings, and there is little difference in the intensity of negative effects between playing and watching violent game.

This study was a randomized before-and-after design of 17 subjects in the experimental group and 17 subjects in the control group to investigate the effects of listening to relaxing music on the mood state and autonomic nervous system, that is, heart rate of hospitalized patients with mental illness. The collected data were analyzed with SPSS V15.0. There was a statistically significant difference between the two groups in mood state and autonomic nervous system, that is heart rate and the effect of listening to relaxation music was objectively verified(<.05). among the subdomains of mood states, tension(<.00), depression (<.00), vitality (<.03), fatigue () <.01), excluding anger (>.39) and confusion (>.33) showed a significant difference, proving that it is an effective intervention method applied to hospitalized mentally ill patients. In the future, we would like to suggest long-term intervention research and development and application, and research on the effect of mood change and heart rate using individual preferred music.

Tele-marketing service has been provided through voice media in a several places such as modern call centers. In modern call centers, they are trying to measure their service quality, and one of the measuring method is a extracting speaker's feeling information in their voice. In this study, it is proposed to analyze speaker's voice in order to extract their feeling information. For this purpose, a person's feeling is categorized by analyzing several types of signal parameters in the voice signal. A person's feeling can be categorized in four different states: joy, sorrow, excitement, and normality. In a normal condition, excited or angry state can be major factor of service quality. In this paper, it is proposed to select a conversation with problems by extracting the speaker's feeling information based on pitches and amplitudes of voice.

정서인식분야에서 현재 활발히 연구되고 있는 방법은 다양한 생체신호를 통해 인간의 감정을 인식하는 것이다. 생리심리학적 연구에서 인간의 감정상태와 생체반응은 강한 상관이 있다고 알려져 있다. 생체신호는 센서 등으로 비교적 간단하게 획득할 수 있으며, 이를 이용한 감정인식은 사회적, 문화적인 차이에 덜 민감하므로 최근에 주목 받고 있다. 본 연구에서는 audio-visual film clips 자극으로 기쁨, 분노, 놀람, 스트레스 4종류의 정서를 유발하고 그에 대한 반응으로써 생체신호를 측정하였다. 그리고 생체신호로부터 feature를 추출하였고, 주성분분석(PCA)로 특징 축소를 수행하였다. 4가지 정서를 분류 한 결과, 9명의 가우시안 프로세스 분류기에 의한 평균 정서 판별율은 64.85 % (57.14~70.0)의 결과를 얻었다.
