The number of traffic accidents in Korea has been increasing since 2014. In most school zones, safety signs are installed to prevent children's traffic accidents. However, it has been known that the effects of those signs are not significant. A variable message sign(VMS), one of the components of Intelligent Transport System(ITS), has emerged as an alternative method. Therefore, this study examines relative effects of two different VMS messages(Timely vs. Continuous) on vehicle speed. Experiments were conducted in two school zones. 6,676 vehicles were measured for speed limit compliance. A counterbalanced multiple baseline design was adopted. The results showed that both types of message are effective in reducing the speed of vehicle. Specifically, A timely message was more effective in slowing down vehicle speed and improving speed limit compliance than a continuous message. The present study suggested that a VMS with human factors can be effective.

Traditionally, self-efficacy, burnout and engagement are defined as work related states of mind, and formally speaking, students are not employees. But, we assume that from a psychological perspective, student core activities can be considered work. Therefore, based on SCT(social cognitive theory), we examine the mediating role of self-efficacy in the prediction of student burnout and engagement, and also the mediation of burnout and engagement between self-efficacy and performance(GPA). There is no research to date wether there would be mediating role of these variables between past success and performance. These effects were analysed in the context of mediating role of the variables in a university in a sample of 438 students. This study utilized a convenience sample drawn from various major scholar area. Results of structural equation modeling analyses were consist with a full mediation model in which academic past success predicts self-efficacy, which in turn, predicts student burnout and engagement. Also our proposed model showed that burnout and engagement are partial or full mediating variables between self-efficacy and performance. Our study's findings provide evidence that engagement fully accounted for the relationship between self-efficacy and performance, and burnout partially explained the relationships. These findings aligns with the general theorizing supported by JD-R model and SCT(social cognitive theory). More specifically, it builds on the JD-R literature as it tests one of the proposed mechanisms in the relationship between job resources and work engagement. Implications of study are discussed, together with limitations and suggestions for future research.

The purpose of this study is to examine how the workplace bullying recognition level of an employee in Korean foodservice industry, which more strongly depends on human services than other industries, influences on job satisfaction and turnover intention. To this end, we collected 250 samples of employees working in the kitchen of family restaurants. Among the collected 250 sample, 241 samples were usable for the analysis excluding 9. The result is as follows. Firstly, there is a difference in average of satisfaction in work according to each group of causes to recognize workplace bullying. That is, the group which vaguely recognizes bullying as for threat to professional status and isolation, and psychological harassment shows higher satisfaction in work than the group which recognizes the bullying well, which is statistically significant. The latter demonstrates more turnover intention than the former. Secondly, the research examining the effects of the causes of workplace bullying over the employees' satisfaction in work and turnover intention shows the following result. The causes to recognize workplace bullying of the employees have a negative effect(-) on job satisfaction on the whole. The causes to recognize workplace bullying of the employees have a positive influence(+) on turnover intention. In conclusion, manager in foodservice industry will need to provide employees with the environment which can help staff improve cooperation, unity and solidarity within the organization.

The purpose of this research is to investigate the determinants of life satisfaction and social support among the elderly. For this purpose, a set of characteristic factors that are supposed to affect elderly life satisfaction were suggested and empirically analyzed. To achieve this study used final analysis with 470 questionnaires which did a questionnaire survey after gathering purposeful sampling method of 500 person who were visiting on Senior Club and Senior Welfare Center. The collected data were analyzed by using the SPSS statistical program. The methods of analysis were frequency, factor analysis, and regression analysis. The results of this study are as follows. Firstly, characteristic factors such as the family relation, health and economic of the elderly have significant impacts on their life satisfaction. Secondly, it was seen that social support regulated the effects of family relation and economic on characteristic factors. The implications of this study are, above all, to build a human network for training, education and social support for career development while participating in the labor market. Such activities could lead to social support for economic independence in old age.

The purpose of this study is to find out influential variables related to Home Management Ability of urban home makers. This study focuses on the following aspects; 1) to find out which variables of sociodemographic variables (ie. home maker's age, level of education-husband, wife, job-husband, wife, income, duration of marriage), of psychological variables (ie. degree of resourcefulness recognition, degree of stress recognition, degree of life level recognition) have significant effects on home management ability. 2) to find out which variables of sociodemographic variables have significant effects on degree of resourcefulness recognition, of stress recognition, and of life level recognition. 3) to identify the influence of significant variables related to home management ability. Data was analyzed by frequency. percentage, mean , F-test, t-test, Duncan's multiple range test. regression analysis , path analysis pearson's r. x2-test. Major findings are as follows; 1) The level of education (husband , wife)and occupation of husband were variables to have influences on home management ability. 2) a. The level of education (husband, wife) and income were variable to have influences on degree of resourcefulness recognition. b. The employment of home makers. income, and the form of family were variables to have influences on degree of stress recognition. c. The level of education (husband, wife) occupation of husband , income , and duration of marriage were variables to have influences on degree of life level recognition. 3) There were significant relationships between home management ability and degree of resourcefulness recognition and of stress recognition (r=0.13, r=-0.12, p<.05). a. The higher degree of resourcefulness recognition, the higher home management ability (x2=11.17. df=4. p<.05) b. The higher degree of stress recognition, the lower home n=management ability (x2=14.64. df=4. p<.01) 4) The education level of homemakers (β =0.15) and income (β=0.12) were variables to have indirect influences on home management ability through the medium of the degree of resourcefulness recognition (β =0.13) 5) The employment of home makers (β=-0.17) was a variable to have indirect influence on home management ability through the medium of the degree of stress recognition(β=-0.12) 6) the education level of husband (β=0.16) and income (β=0.32) were variables to have direct influence on degree of life level recognition. 7) The degree of life level recognition (β=0.13) and education level of home makers (β=0.17) were variables to have indirect influences on home management ability through the medium of the degree of resourcefulness recognition (β=0.13) 8)The degree of life level recognition (β=-0.22) the employment of home makers(β=-0.17) and the from of family(β=-0.10) were variables to have indirect influences on home management ability through the medium of the degree of stress recognition.

One of the major causes of morbidity and mortality in breast cancer patients is delay in seeking help. Leventhal's self-regulation model provides an appropriate framework to assess delay in seeking help. The aim of this study was to investigate the relationship between "illness perception" and "help seeking delay" in breast cancer patients based on Leventhal's self-regulation model. In this correlational descriptive study with convenience sampling conducted in 2013, participants were 120 women with breast cancer who were diagnosed in the last year and referred to chemotherapy and radiotherapy centers in Rasht, Iran. Data collection scales included demographic data, Revised Illness Perception Questionnaire (IPQ-R)and a researcher made questionnaire to measure the delay in seeking help. Pre-hospital delay (help seeking delay) was evaluated in 3 phases (assessment, disease, behavior). The data were analyzed using SPSS-19. The mean (SD) age calculated for the patients was $47.3{\pm}10.2$. Some 43% of the patients had a high school or higher education level and 82% were married. The "pre-hospital delay" was reported ${\geq}3months$. Logistic regression analysis showed that none of the illness perception components were correlated with appraisal and behavioral delay phases. In the illness delay phase, "time line" (p-value =0.04) and "risk factors"(p-value=0.03) had significant effects on reducing and "psychological attributions" had significant effects on increasing the delay (p-value =0.01). "Illness coherence" was correlated with decreased pre-hospital patient delay (p-value<0.01). Women's perceptions of breast cancer influences delay in seeking help. In addition to verifying the validity of Leventhal's self-regulation model in explaining delay in seeking help, the results signify the importance of the "illness delay phase" (decision to seek help) and educational interventions-counseling for women in the community.

This study examined the effect of job stress and mental health factors on the oral symptoms of caring service workers in Seoul. For the research method, a survey was conducted from July 24 to August 6, targeting 150 caring service workers. The survey items were job stress, mental health (physical symptoms, anxiety, and insomnia), and self-diagnosed oral symptoms. The results of the study were as follows. Job stress (p=0.001) had a significant effect on the oral symptoms. In addition, physical symptoms (p<0.001), anxiety symptoms (p<0.001), and insomnia symptoms (p<0.001) all had significant effects on the oral symptoms. Among the risk factors, physical symptoms had the greatest influence on oral symptoms. In addition, according to the correlation result of job stress, anxiety symptoms, insomnia symptoms, oral symptoms, as job stress increases, physical symptoms (p<0.001), anxiety symptoms (p<0.001), insomnia symptoms (p<0.001), oral symptoms (p<0.01) showed an increasing positive correlation and a statistically significant difference. Physical and psychological labor power is greatly exhausted by care service workers performing tasks that require physical and mental care for those who are being cared for. Therefore, there is a need for systematic expansion measures for the mental health of workers and the introduction of customized oral health education programs to improve oral health because improved health and oral health conditions can increase work performance.

Stroop effect(Stroop, 1935) is a reliable paradigm which has been used in various psychological research. Although classic Stroop experiment used color and color name for experimental stimuli, subsequent research reported that a color(e.g. green) and an object(e.g. grass) which displays a typical color show similar effects depending on color-object congruency(Klein, 1964). Because past research that used Stroop effect to investigate semantic representation tested association between concrete object and color, they predominantly used concrete nouns and their corresponding color names as stimuli(e.g. Dalrymple-Alford, 1968, 1972; Klein, 1964). Recently, Sherman and Clore(2009) reported that response time to white or black words is affected by moral value of words (e.g., honesty, crime) even when the words do not have specific referents. Based on this result, we tested association between thermesthesia-related adjectives(e.g., 따스한, 냉정한) and color(warm color, cold color) using Stroop task. The results showed that subjects were faster in their response to color when adjective-color was congruent than when incongruent, and there was an interaction between color and meaning of adjectives. The Stroop effect in this research is unique because, contrary to previous research that used concrete nouns, the effect was obtained even with abstract adjectives which do not have specific referents. In addition, unlike Sherman and Clore(2009) that used achromatic color, our results show that Stroop effect obtains between abstract adjectives and chromatic color.

This study investigated the effects of song discussion on depression and rehabilitation motivation in stroke patients. Older adults with chronic stroke participated in this study: nine for the experimental group and eight for the control group. The experimental group was divided into three subgroups and participated in 12 sessions over 6 weeks. Target lyrics were selected by the investigator among popular songs from the participants' young adulthood. The song-based discussion was facilitated to address issues targeted at supportive, insight-focused, or reconstructive stage. The control group was provided with delayed intervention. At pre and posttest, the short form of Geriatric Depression Scale and the Rehabilitation Motivation Scale were measured. The experimental group showed significantly decreased depression and significantly increased rehabilitation motivation (p < .01), while the control group showed no significant changes. Positive changes were also observed in all subcategories of rehabilitation motivation in the experimental group, particularly in significantly increased task-oriented motivation and decreased amotivation. This study suggests that song discussion will be effectively applied in rehabilitative settings to address psychological issues of older adults with stroke.

This study attends to the effects of political entertainment as a newly emerging television genre on citizens' political talk. Particularly, this study suggests audience involvement and political information efficacy as key psychological factors that mediate the relationship between political entertainment and political discussion. More specifically, audience involvement was deemed as a conclusive concept that consists of such sub-dimensions as audience identification and parasocial interaction with program characters and transportation into the messages. Among 317 participants in an online survey, a total of 273 subjects, who had at least some viewing experience with political entertainment TV programs, were included in the final analysis. According to the findings, softer programs that piggyback political information on top of their entertainment content were more likely to increase viewers' identification and transportation. The viewer experience of identification further heightened the level of political information efficacy, which in turn positively contributed to one's willingness to participate in political talk and to hear the other side. It also appeared that political information efficacy significantly mediated the relationship between political entertainment viewing and political talk.
