  • Electroencephalographic(EEG) is used to record activities of human brain in the area of psychology for many years. As technology develope, neural basis of functional areas of emotion processing is revealed gradually. So we measure fundamental areas of human brain that controls emotion of human by using EEG. Hands gestures such as shaking and head gesture such as nodding are often used as human body languages for communication with each other, and their recognition is important that it is a useful communication medium between human and computers. Research methods about gesture recognition are used of computer vision. Many researchers study Emotion Recognition method which uses one of EEG signals and Gestures in the existing research. In this paper, we use together EEG signals and Gestures for Emotion Recognition of human. And we select the driver emotion as a specific target. The experimental result shows that using of both EEG signals and gestures gets high recognition rates better than using EEG signals or gestures. Both EEG signals and gestures use Interactive Feature Selection(IFS) for the feature selection whose method is based on a reinforcement learning.

  • The intent of this study is to develop system dynamics model for assessment of organizational and human factors in nuclear power plant which can contribute to secure the nuclear safety. Previous studies are classified into two major approaches. One is engineering approach such as ergonomics and probability safety assessment(PSA). The other is social science approach such like sociology, organization theory and psychology. Both have contributed to find organization and human factors and to present guideline to lessen human error in NPP. But, since these methodologies assume that relationship among factors is independent they don't explain the interactions among factors or variables in NPP. To overcome these limits, we have developed system dynamics model which can show cause and effect among factors and quantify organizational and human factors. The model we developed is composed of 16 functions of job process in nuclear power, and shows interactions among various factors which affects employees' productivity and job quality. Handling variables such like degree of leadership, adjustment of number of employee, and workload in each department, users can simulate various situations in nuclear power plant in the organization side. Through simulation, user can get insight to improve safety in plants and to find managerial tools in the organization and human side. Analyzing pattern of variables, users can get knowledge of their organization structure, and understand stands of other departments or employees. Ultimately they can build learning organization to secure optimal safety in nuclear power plant.

  • Car crashes are the leading cause of death for persons of every age. Specially, human-related factor has been known to be the primary causal factor of such crashes than vehicle-and environmental-related factors. There are various studies to analyze driver's behavior and characteristics in driving for reducing the car crashes in many areas of car engineering, psychology, human factor, etc. However, there are almost no studies which analyze mainly the human errors in driving and estimate their probabilities in terms of human reliability analysis. This study estimates the probability of human error in driving, i.e. driver error probability. First, fifty driver errors are investigated through DBQ (Driver Behavior Questionnaire) revision and the error likelihoods in driving are collected which are judged by skillful drivers using revised DBQ. Next, these likelihoods are converted into driver error probabilities using the results that verbal probabilistic expressions are changed into quantitative probabilities. Using these probabilities we can improve the warning effects on drivers by indicating their driving error likelihoods quantitatively. We can also expect the reduction effects of car accident through controlling especially dangerous error groups which have higher probabilities. Like these, the results of this study can be used as the primary materials of safety education on drivers.

  • Purpose: This study investigates human error accidents in the Korean railway sector, emphasizing the need for systematic management to prevent such incidents, which can have fatal consequences, especially in driving-related jobs. Research design, data and methodology: This paper analyzed data from the Aviation and Railway Accident Investigation Board and the Korea Transportation Safety Authority, examining 240 human error accidents that occurred over the last five years (2018-2022). The analysis focused on accidents in the driving, facility, electric, and control fields. Results: The findings indicate that the majority of human error accidents stem from negligence in confirmation checks, issues with work methods, and oversight in facility maintenance. In the driving field, errors such as signal check neglect and braking failures are prevalent, while in the facility and electric fields, the main issues are maintenance delays and neglect of safety measures. Conclusions: The paper concludes that human error accidents are complex and multifaceted, often resulting from a high workload on engineers and systemic issues within the railway system. Future research should delve into the causal relationships of these accidents and develop targeted prevention strategies through improved work processes, education, and training.

  • As human life and welfare become more valued in the Fourth Industrial Revolution era, the role and mission of human ecology are expanding. Therefore, a career exploration and education program for high school students covering all the academic fields of human ecology may be necessary. To investigate what would be needed to develop such a program, a focus group interview (FGI) targeting experts within the same field and a survey targeting high school students were conducted. As a result of the FGI, a total of 3 categories and 7 subcategories were identified. The three categories included "human ecology and high school education," "human ecology and career choices," and "education program development and management in human ecology." The results of the high schoolers' survey showed that they had a moderate level of awareness about careers related to human ecology majors, but their interests and known information about human ecology programs in universities were low. Within the sub-content of each major, the contents with the highest educational needs were fashion product management, nutrition by disease, housing market analysis, personal financial management, and children's rights and welfare. If a career exploration and education program is implemented in the future, the most preferred type is a mentoring program by professors, students, and graduates in the field of human ecology. In conclusion, it is necessary to develop and implement an integrative education program about human ecology majors based on the educational needs of high school students.

  • Background: The influence of sociocultural factors on human reliability within an open sociotechnical systems is highlighted. The design of such systems is enhanced by experience feedback. Methods: The study was focused on a survey related to the observation of working cases, and by processing of incident/accident statistics and semistructured interviews in the qualitative part. In order to consolidate the study approach, we considered a schedule for the purpose of standard statistical measurements. We tried to be unbiased by supporting an exhaustive list of all worker categories including age, sex, educational level, prescribed task, accountability level, etc. The survey was reinforced by a schedule distributed to 300 workers belonging to two oil companies. This schedule comprises 30 items related to six main factors that influence human reliability. Results: Qualitative observations and schedule data processing had shown that the sociocultural factors can negatively and positively influence operator behaviors. Conclusion: The explored sociocultural factors influence the human reliability both in qualitative and quantitative manners. The proposed model shows how reliability can be enhanced by some measures such as experience feedback based on, for example, safety improvements, training, and information. With that is added the continuous systems improvements to improve sociocultural reality and to reduce negative behaviors.

  • 재난(災難)은 외면적으로는 인간과 사회에 감당하기 힘든 피해를 주는 엄청난 사건이며, 내면적으로는 인간의 마음속에 있는 온갖 종류의 개인적, 집단적 콤플렉스들을 자극한다. 2014년 세월호 침몰 사고는 많은 인명이 갑자기 사망한 인재이며, 대한민국뿐 아니라 전 세계의 수많은 사람들이 큰 심리적 충격을 받았다. 저자는 이 사고의 재난정신건강지원에 직접 참여하면서, 현대 기술 문명의 발달에 대한 자만심이 무너지고 거대한 슬픔과 무력감에 빠진 사람들을 만나는 과정에서 의식적, 무의식적 반응들을 분석심리학적 관점에서 고찰하고 연구해야 할 필요성을 실감했다. 본 연구는 신화와 암각화를 중심으로 선사시대 인간의 재난에 대한 관념과 대처양식을 조사하여, 그 속에 나타난 보편적, 원초적, 원형적 인간 심성과 문화적 특수성을 찾아내고 그 의미와 지혜를 발견하여 현대의 재난대응의 문제점과 개선의 방향을 고찰하고자 한다. 세계 도처의 창세신화들은 태초에 우주적 창조의 일부로서 재난이 있었다는 것을 보여준다. 인류는 선사시대로부터 세계의 주기적 경신(更新)이라는 파괴와 창조의 양면성의 관념에서 재난을 이해하고 대처했으며, 금기의 위반이 재난을 일으킨다는 관념을 갖고 있었다. 재난은 외견상 파괴적 작용을 통해서 의식의 근본적 경신(更新)을 지향하는 '자기(Self)'의 의도로 해석할 수 있다. 재난이라는 정신적 위기 상황에서 행해진 다양한 의례는 무의식과의 소통을 통해 인간의식을 새롭게 하고, 전체 정신의 조화를 추구하는 정신적 재생의 기회가 됐다. 현대 사회는 재난대응에 있어서 외면적, 기술적, 행정적 대응에만 치중한 나머지 고통받는 인간의 심성과 내면적 대처의 중요성을 간과하고 있다. 우리는 재난의 발생을 결정할 수는 없지만, 재난의 대처방식을 결정할 수는 있다. 외면적 재난대응을 힘써 발달시킴과 동시에, 재난의 의미를 성찰하여 인간의 심성을 살피는 내면적 재난대응을 함으로써 인간은 재난을 통해 고통의 의미를 발견하고 성숙의 길로 나아갈 수 있을 것이다.
