관객의 감정 반응은 개별 관객들의 반응을 관측하여 판단할 수 있다. 영상 카메라를 이용한 시각적 데이터를 분석하여 활용하는 방법을 이용할 경우, 관객의 반응을 적은 비용으로 데이터를 추출하여 판단할 수 있는 것이 가능하다. 하지만, 영상 카메라를 이용할 경우 다수의 관객으로부터 발생하는 대규모의 영상 신호로부터 관객의 특징값들을 분석하여 반응을 판단하기 위한 방법과 시스템이 필요하다. 이를 위해 본 논문에서는 관객의 영상 데이터를 신경회로망 기법을 이용하여 관객의 반응을 관측하여 판단하는 방법과 시스템을 제안하고, 기존의 관객석을 고정적인 영역으로 분할하여 데이터를 취합하여 분석하기 때문에 발생하는 문제를 개선하기 위해 얼굴 검출을 통해 자동적으로 관객 영역을 분할하는 방법을 제안한다. 또한 실험을 통해 기존의 고정적으로 관객 영역을 지정하는 방법에 비해 10.5 %(7.75의 Hit Ratio)의 성능향상이 있음을 확인하였다. 이를 통해 제안하는 방법이 실제 관객 반응을 판단하는데 더 적합하다는 것을 알 수 있다.

Objectives : Indirect contact with trauma may occur when a person empathically listens to detailed descriptions, exposing the person to intense emotional pain from trauma victims. Although less severe than direct trauma, indirectly traumatized persons may experience the same fear, rage, and despair as direct trauma victims. This phenomenon has been variously termed vicarious trauma, traumatic countertransference, burnout, compassion fatigue, and secondary traumatic stress. Using a psychiatric symptoms questionnaires, this study investigated the effects of indirect exposure to co-worker's trauma on the mental health of firefighters who had not directly experienced traumatic events in the previous year. Methods : We administered self-report questionnaires, such as the Impact of Event Scale-Revised (IESR) and Alcohol Use Disorder Identification Test (AUDIT), to firefighters working at two fire stations in a metropolitan city. We analyzed 188 of 232 collected surveys, after excluding falsely entered data (28 cases) and questionnaires by directly-traumatized victims (16 cases). Results : Alcohol consumption and posttraumatic stress disorder (PTSD) symptoms, as determined by the AUDIT and IES-R, were significantly higher in the indirectly-traumatized group. The ratio of high-risk members scoring higher than 23 in IES-R was larger in the indirectly traumatized group, although this was not statistically significant. Conclusion : Alcohol consumption was significantly higher in the indirectly traumatized group. This group also included more members at high risk for PTSD. Further research, with a larger group of indirectly traumatized firefighters and ongoing investigation of PTSD development and other psychiatric symptoms, is needed.

Purpose: Premenstrual syndrome(PMS) is a collection of physical, psychological and emotional symptoms related to a women's menstrual cycle. The symptoms are related with Autonomic Nervous system. The purpose of this study is to investigate the activity of Autonomic Nervous system in women with premenstrual syndrome(PMS) by using Heart Rate Variability(HRV). Methods: We studied 26 patients visiting ㅇㅇ hospital from 26th December 2005 to 26th April 2006. Activity of Autonomic Nervous system was assesed by means of Heart Rate Variability(HRV). The subjects were categorized in two groups, PMS group(10) and non-PMS group(16). We studied the difference of HRV between two groups by Mann-Whitney U-test using SPSS for windows (version 12.0). Results: SDNN of PMS group was non-significantly lower than non-PMS group. RMS-SD of PMS group was significantly lower than non-PMS group. Mean PR of PMS group was non-significantly higher than non-PMS group. TP, VLF, LF, HF norm of PMS group was non-significantly lower than non-PMS group. HF of PMS group was significantly lower than non-PMS group. LF norm, LF/HF ratio of PMS group was non-significantly higher than non-PMS group. Conclusion: The results suggest that PMS can be related to decreased activity of parasympathetic nervous system. HRV can be useful to diagnose PMS. The more studies to diagnose PMS would be needed.

This study aimed to investigate whether breed, sex, and age affected temperament differently (more or less neophobic) in mature horses during a novel object test. The study included Jeju crossbred (n = 12, age = 9.42 ± 4.57 y), Thoroughbred (n = 15, age = 10.73 ± 3.09 y), and Warmblood horses (n = 12, age = 13.08 ± 3.55 y) with the females (n = 22, age = 11.36 ± 4.24 y) and geldings (n = 17, age = 10.65 ± 3.66 y). Jeju crossbreds (Jeju horse × Thoroughbred) are valuable considering their popular usage in Korea, but limited studies have explored temperament of Jeju crossbred horses. A trained experimenter touched the left side of the neck with a white plastic bag (novel object). The test ended when the horse stopped escape response and heart rate (HR) dropped to baseline. Behavioral score and escape duration were measured as behavioral variables. Multiple variables related to HR and heart rate variability (HRV) were measured to reflect emotional state. These included basal HR (BHR), maximum HR (MHR), delay to reach maximum heart rate (Time to MHR), standard deviation of beat-to-beat intervals (SDNN), root mean square of successive differences (RMSSD), and ratio of low to high frequency components of a continuous series of heartbeats (LF/HF). Statistics revealed that Thoroughbreds had significantly higher behavioral scores, and lower RMSSD than Jeju crossbreds (p < 0.05), suggesting greater excitement and fear to the novel object in Thoroughbreds. None of the behavioral or cardiac parameters exhibited sex differences (p < 0.05). Age was negatively correlated with SDNN and RMSSD (p < 0.05), indicating that older horses felt more anxiety to the novelty than younger horses. Thoroughbreds and females had distinct correlations between behavioral and HRV variables in comparison with other groups (p < 0.05), implying that escape duration might be a good indicator of stress, especially in these two groups. These results are expected to improve equine welfare, safety and utility, by providing insights into the temperament of particular horse groups, to better match reactivity levels with specific functions.

Purpose: This study examined the association between smoking and delayed neuropsychological sequelae (DNS) in acute carbon monoxide (CO) poisoning. Methods: Patients admitted to the medical center emergency department from March 2016 to March 2017 because of CO poisoning were examined retrospectively. The patients were divided into two groups: DNS and Non-DNS group. Multiple factors were analyzed to explain DNS, which was assessed by motor disturbances, cognitive impairment, dysphagia, Parkinson-like syndromes, epilepsy, and emotional lability in CO poisoning. Results: A total of 120 patients were included. The factors related to DNS were smoking (pack-years) (p=0.002) and initial carbon monoxide-hemoglobin level (p=0.015). On the other hand, after multivariate logistic regression analysis, smoking (Odds ratio 1.07; 95% CI, 1.02-1.13; p=0.004) was the only factor associated with DNS. Conclusion: Smoking is a very reliable factor for predicting the occurrence of DNS. A history of smoking in patients who suffer from CO intoxication is important. If a patient smokes, treatment should be started actively and as soon as possible.

Background: Emigration of health-care workers is a problem within global health systems which affects many countries, including Peru. Several factors have caused health-care workers to emigrate, including burnout syndrome (BS). This study aims to identify the association between BS and its dimensions with the intention of physicians and nurses to emigrate from Peru in 2014. Methods: A cross-sectional study, based on a secondary analysis of the National Survey of Health Users (ENSUSALUD - 2014) was conducted. Sampling was probabilistic, considering the 24 departments of Peru. We include the questionnaire for physicians and nurses, accounting for 5062 workers. BS was measured by the Maslach Burnout Inventory-Human Services Survey. Adjusted odds ratio (OR) was calculated using multiple logistic regression. Results: Of the study population, 44.1% were physicians, 37.7% males, and 23.1% were working in Lima. It was found that 2.8% [95% confidence interval (CI): 2.19-3.45] of health-care workers had BS. The overall prevalence of intention to emigrate among health-care workers was 7.4% (95% CI: 6.36-8.40). Association was found between BS and intention to emigrate in Peruvian health-care workers (OR = 2.15; 95% CI: 1.05-4.40). Emotional exhaustion was the BS dimension most associated with intention to emigrate (OR = 1.80; 95% CI: 1.16-2.78). Conclusion: Physicians and nurses from Peru who suffered from BS were more likely to have intention to emigrate. Policies should be established to reduce BS as a strategy to control "brain drain" from health-care workers of Peru.

In order to find out the relationship between the Eight Principle Pattern Identification of Yin-Yang, Exterior-Interior and the Sasang constitution, we analyzed the clinical data from 500 women with menstrual pain and women without menstrual pain. In the previous study, the subject's information of Typology Complexion Pulse and Symptom was collected, and Eight Principle Pattern Identification was executed based on this. Later, The relationship between the Sasang constitution and the Eight Principle Pattern Identification was statistically analyzed. The obvious difference between the experimental group and the control group in the patterns of Yin-Yang and Exterior-Interior is that patients who complain of menstrual pain do not maintain harmony with the yin-yang ratio, it can be said that the patterns of Yin-Yang and Exterior-Interior can be a identification standard that significantly obscures the condition of the disease. There was a significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Yin-Yang. There was no significant difference between the Sasang constitution and the Eight Principle Pattern Identification of Exterior-Interior. It is assumed that the relationship between the Eight Principle Pattern Identification and the Sasang constitution has changed depending on the difference a view of emotional Qi and pathogenic Qi.
