In this study, the researchers analyzed the 2015 revised 3rd~6th grade Korean mathematics textbooks from the aspects of social justice in mathematics education. For this study, the researchers constructed a textbook analysis framework for social justice subjects, which categorized by social issues, economy education, democratic education, personality education, safety education, environmental education, and career education. As a result, the 2015 revised elementary mathematics textbooks were reflected the subject matter of social justice in the order of social issues, economic education and democratic education, personality education and environmental education, safety education and career education. Also, the subject of social justice appears in all 3rd~6th grade mathematics textbooks, but it is not explicitly dealt with by combining it with mathematical content. The researchers suggested that mathematics lessons should be developed including social justice issues aligned with elementary mathematics contents.

In road work zones, pedestrian workers' habituated inattention to warning alarms from construction vehicles can lead to fatal accidents. Previous studies have theorized that human factors such as personality traits may affect workers' inattentiveness to workplace hazards. However, there has been no study that directly examined how road construction workers' personality traits affect their attention to warning alarms within a work zone and the likelihood of engagement in a struck-by accident. This study examines how workers' sensation-seeking (especially boredom susceptibility) is related to inattention to warning alarms while performing a task in road work zones. An experiment with actual road construction workers was conducted using a virtual road construction environment. Workers' attention to repeatedly presented warning alarms was measured using eye-tracking sensors. In response to workers' frequent inattentive behaviors, a virtual accident was simulated. Results revealed a significant association between boredom susceptibility and workers' engagement in the virtual accident, a consequence of inattentiveness to warning alarms. The findings suggest that workers' personality traits predispose them to tune out warning alarms and become vulnerable to accidents in road work zones. The findings of this study can be used to develop targeted interventions aimed at preventing workers' inattention to repeatedly exposed workplace hazards, thereby contributing to reducing fatal accidents in road work zones.

본 연구는 다변량 통계분석을 이용하여 자동차사고성향에 대한 공통적인 특성을 찾아내고 그것이 심리적 성격특성과 관련이 있는가를 분석하고자 수행되었다. 이를 위하여 학생집단, 일반인집단 그리고 운전기사집단의 성격적 특성과 자동차사고경험 혹은 그 가능성을 비교 검토하였다. KG식 일반생활질문지에 의한 설문분석결과에 따르면 사고친화성향에 따라 2개의 집단으로 분류하는 것이 타당하다고 판단되었고, 수량화분석에 의해서도 집단을 구분할수 있었지만 일반인과 운전자 집단간에는 차이가 있었다.

The number of traffic accidents has been decreased since 2000; however, the downward trend of crash occurrence has been slower after 2006. A few decades ago, physical improvement projects such as alignment improvement and the installation of safety facilities were usually implemented to decrease the occurrence of traffic accidents, but the effects of physical improvement on safety have been gradually decreased. The main objective of this study is to identify how the drivers' characteristics affect and/or are related to traffic accidents. Most of previous works have focused on revealing the difference of the nature of the drivers between the drivers who have no experience and the drivers with experience of traffic accidents. This study tries to analyze the habitual accidents proneness through a survey of drivers' personalities for drivers who were involved in traffic accidents at least once. As a result, nine personality factors were found to be statistically significant: Neuroticism(N), Lie(L), Psychoticism* Neuroticism(PN), Psychoticism*Lie(PL), Extraversion*Lie(EL), Neuroticism*Lie(NL), Impulsiveness(IMP), Venturesomeness(VEN), Empathy(EMP). Among these factors, single character factors were found to increase accidents, whereas complex factors were found to decrease the occurrence of accidents.

Purpose: The purpose of this study was to examine lifestyle, BMI, BP, and lipids profiles in male subjects and to explore the relationships among variables. Methods: A total of 148 male subjects were recruited from one life insurance company from December 1, 2005 to February 28, 2006. Data collection methods were structured questionnaire, anthropometry and serum analysis. The relationships among lifestyle, BMI, BP, and serum lipid profiles were assessed by descriptive analysis, t-test, ANOVA, and partial Pearson's correlation coefficient of variables after controlling for age, educational level, and economic status. Results: The mean BMI of the participants was relatively high as 25.38(range: 18.38 - 32.83). The differences of serum lipid profiles according to age, educational level, and economic status were significant. 'Use of caffeine and drugs'(r = -.187, p < .05) and 'consciousness of safety'( r= -.200, p < .05) was negatively related to BMI. Higher score of 'type of personality' domain was correlated with lower systolic BP(r = -.221, p < .01) and lower diastolic BP(r = -.195, p < .05) and was positively correlated with HDL(r = .191, p < .05). Conclusion: 'Use of caffeine and drugs', 'consciousness of safety' and 'type of personality' of lifestyle as well as 'dietary habit' and 'exercise' played a key role in circulatory disease.

Recently, increases in major disasters such as fires, earthquakes and typhoons have raised public expectations for safety. In addition to this increase in expectations of safety, the government continues to push for more manpower and better treatment for firefighters who are operating in the disaster scene. Despite the improvement of working conditions and increased welfare for firefighters, however, the incidence and turnover of various mental diseases continues to increase. It is reported that many of the diseases such as post-traumatic stress disorder and the turnover of firefighters are due to a mismatch in individual's personality and work environment. In this study, 108 firefighters were evaluated for their vocational aptitude in the new curriculum. Based on the analysis results, new firefighters were proposed to provide employment and education training improvements, and to provide job security suitable for the individual's personality type through the introduction of the vocational aptitude test for firefighters who are working in the fire service. In addition, we would like to use the vocational aptitude test as a material for reducing post-traumatic stress disorder and increasing turnover through long-term tracking and observation, rather than from a one-off perspective.

Over the past decades there has been a growing body of researches that examines the psychological traits related to safety outcomes. After briefly reviewing the relationships between psychological dispositions and safety outcomes, we empirically examine the relationships with 2 samples of 1,102 participants. Fifteen psychological dispositions (big 5 personality, locus of control, cognitive failure, affection from job and relations, 4 achievement goal orientations, self-efficacy, fatigue, and depression) and four psychological outcomes (safe behavior, unsafe behavior, accidents, and injuries) are examined. After covariance structure modeling variances of safety outcomes are well explained by simple 4 dispositions of consciousness, mastery-approach goal orientation, self-efficacy, and depression. We name them 'core safety disposition', and name four psychological outcomes 'safety consciousness', and the relationships between those latent variables are stronger than between measurement variables. We propose core safety disposition as a cause of safety consciousness, and discuss implications for research and practices.

Job stresses are realized as harmful factors affected workers' mental health. Job stresses can be defined as the physical and emotional responses that are occurred when the job requirements should be beyond the workers' abilities, followed with health problems and even work-related injuries. Job stresses could be resulted from the work environment and conditions related with workers' personality. This study is conducted to evaluate the job stresses for managers in the construction industry, by the questionaires which collected 302(75.5%) among 400 ones. The evaluation items are the levels of job stresses and stressors as well as the relationship between the variables. The controls should be recommended for physical and mental health.

The purpose of this study was to propose appropriate requirements to obtain a pilot's license in order to improve the safety of pilotage related to a survey of experts involved with pilotage. The survey has been conducted by experts from stakeholders in various fields. To suggest requirements for the license, a hypothesis test has been conducted. It turns out that onboard experience with higher gross tonnage is eligible for pilot. Secondly, it is required to have onboard experience of more than one year as a captain, within 5 years from the date that the individual takes the pilot's written test, with 5 years onboard experience as a captain. Lastly, if personality and aptitude tests are added to the requirements to obtain a pilot's license, the safety of pilotage will increase rapidly.
