The variable message sign(VMS) is a representative traffic information service medium which has the largest users and is provided and operated by a governmental agency. In this paper, we focused on psychological responses of individuals who use VMS traffic information in the light of the need for VMS to provide user-oriented service. A total of t재 scenarios were plotted to conduct our experiment on a virtual test track. A stress index analysis on VMS location, the first scenario, showed the lowest stress value at the point of 1.5 kilometers before the exit. A stress index analysis on the contents of VMS information (communication, time, and speed), the second scenario, showed the lowest stress value at time information.

The purpose of this study was to examine the effects of an elderly people's health promotion program performed in a senior center located in J-si. Most interesting were the effects on the physical, physiological, and psychological parameters for senior center participation of the elderly. A nonequivalent control group pre-posttest design was employed. A total of 41 people living in J-si were assigned to either an experimental group (n=21) or control group (n=20). The experimental group was provided with the eight-week elderly people's health promotion program from May 1 to September 2 in 2019. The data were analyzed using SPSS/WIN 24.0 using descriptive statistics, 𝒙²-test, Fisher's exact test, and t-test. The results indicated a significant difference between the experimental group and control group with respect to the scores of the physical parameters, including right grip strength (t=-3.01, p=.004) and flexibility of the waist (t=-2.11, p=.09); the physiological parameters, including the systolic blood pressure (t=-3.02, p=.004); and psychological, including depression (t=2.42, p=.020), hopelessness (t=5.22, p<.001), and quality of life (t=4.28, p<.001). Therefore, the elderly people's health promotion program with senior center participation of the elderly is a useful nursing intervention program that can improve the right grip strength, flexibility waist, reduce the systolic blood pressure, depression and hopelessness, and improve the quality of life.

This study was based on Job Demand-Resource Model and tried to understand the causes of presenteeism that work but have decreased productivity in spite of health problems. In order to examine the psychological causes of presenteeism, we reinterpreted job resources as psychological capital, which is a psychological resource of personal dimension, and examined the positive and negative aspects of job demands by classifying job demands into challenge and hindrance stressors. Data analysis was conducted using SPSS 21.0 and AMOS 20.0 statistical programs. Data were gathered from 329 employee in Korea. The results of this study are as follows: Hindrance and challenge stressor and psychological capital were fully mediated in the influence of presenteeism through job engagement, and hindrance stressor and psychological capital were fully mediated in the influence of presenteeism though job burnout. Based on the results.

With increasing interest in the 4th industrial revolution, data-driven scientific methodologies have developed. However, there are limitations of data collection in the real estate field of research. In addition, as the public becomes more knowledgeable about the real estate market, the qualitative sentiment comes to play a bigger role in the real estate market. Therefore, we propose a method to collect quantitative data that reflects sentiment using text mining and k-means algorithms, rather than the existing source data, and to predict the direction of housing index through artificial neural network learning based on the collected data. Data from 2012 to 2019 is set as the training period and 2020 as the prediction period. It is expected that this study will contribute to the utilization of scientific methods such as artificial neural networks rather than the use of the classical methodology for real estate market participants in their decision making process.

The purpose of this study was to identify the relationship between multi-cultural family husbands' stress related to their wife and their psychological abuse based on the Stress theory of Lazarus et al. Data from 271 subjects that answered to all questions regarding the subjects' social demographic characteristics, and the husbands' stress related to their wife and their psychological abuse of their wife in statistical analyses. To analyze the data, a study model was set using multi-cultural family husbands' stress related to their wife as an independent variable and their psychological abuse of their wife as a dependent variable and the goodness-of-fit of the model for the data and the relationship between the variables were reviewed using a structural equation model. According to the results, the goodness-of-fit index of the model satisfied the statistical acceptable standard with CFI=0.909 and RMSEA=0.057. The relationship between the variables indicated that multi-cultural family husbands' stress related to their wife had significant effects on their psychological abuse of their wife.

South Korea has become richer economically than the past, but still level of happiness is low. This research was conducted to verify the relationships among mental health, self-forgiveness, and psychological well-being. Participants were 232 college students in an university in Seoul. Methods of data analysis were ANOVA, regression analysis, and path analysis. As a result of analyses, first, MMPI-2 clinical scales which showed significant correlation with psychological well-being were as follows: Hs, D, Pd, Pa, Pt, Sc, Si. Second, PSY-5 scales which showed significant correlation with psychological well-being were as follows: PSYC, NEGE, INTR. Third, stepwise regression analysis revealed that Sc, Si and Pd among clinical scales of MMPI-2 were associated with psychological well-being. Fourth, PSYC, NEGE and INTR among clinical scales of PSY-5 scales were associated with psychological well-being. Fifth, self-forgiveness had a significant mediating effect in the relationship between mental health and psychological well-being. Based on the results, implications related to importances of mental health and self-forgiveness were discussed for increasing psychological well-being of college students.

This paper tries to develop a composite indicator for measuring trends and prospects of national technology commercialization through integrating large amount of information into easily understood formats. The indicator is composed of five sector indicators including activity, cooperation or networking, performance, environment, and psychology indicators, each of which aggregates five individual variables. The statistical method of standardizing and weighting variables in the aggregation process are also mentioned. This indicator is expected to be a useful monitoring and policy tool for the Korean technology market.

본 연구는 발달적 위기에 놓여있는 중년여성의 피로도와 스트레스 저항력 그리고 정서와의 상관관계를 알아보기 위하여 뇌신경 생리학적 지표인 뇌파 측정을 이용하여 분석해 보고자 하였다. 2005년 3월부터 2009년 6월까지 한국정신과학연구소에 뇌파 측정을 의뢰한 우리나라 중년여성 4403명(35세~65세)을 기준으로 선정된 뇌기능 지수(긴장도, 항스트레스지수, 정서지수)를 시계열 선형분석과 상관분석으로 한 결과 중년여성의 피로도, 스트레스 저항력 그리고 정서에는 밀접한 관계가 있었다. 그러므로 사회적으로나 가정적으로 성숙하고 책임감 있는 중년여성의 역할이 필요한 현대사회에서, 중년기의 심리적 생리적 문제에 적극적으로 대처하는 것이 개인생활은 물론 가족의 원만한 기능과 안녕을 유지, 증진하는데 반드시 필요하다.

"이성적이며 이상적인 합리적 인간"을 가정하는 기존 경제학의 이론이 항상 실제 상황과 일치하지는 않는 것으로 알려져 있다. 이의 대안으로 나온 행동경제학은, 인간의 경제적 의사결정에 심리, 인지, 감정, 사회문화적 배경 등이 영향을 미친다고 본다. 본 연구에서는 행동경제학에 의거하여, 개인의 감정과 경험이 경제적 의사결정에 영향을 미치는지 여부를 빅데이터 모델을 활용하여 분석하였다. SNS 여론으로는 Reddit, 주가지수로는 S&P 500 을 선정하였다. 수집한 텍스트 데이터를 전처리와 감정분석을 통해 독립변수 값으로 사용했고, 주가지수 등락의 방향성을 종속변수로 사용하여 로지스틱 모형을 구성했다. 모델을 활용하여 분석한 결과 Public sentiment 와 Market sentiment 간 양의 상관관계를 확인할 수 있었다. 또한, lag 를 설정하는 모델이 정확도가 더욱 높음을 확인해, 기존 경제학의 EMH 와 대립되는 바를 확인할 수 있었다. 하지만 최적의 lag 산정을 위해, 더 광범위한 데이터를 바탕으로 한 후속연구가 필요하다.
