The purpose of this study is to verify the mediating effect of job stress between childcare teacher personality and child abuse, and provides basic data on personality education and coping strategies for childcare teachers' job stress. A survey was conducted on 326 childcare teachers working at daycare centers in Incheon, Korea. The collected questionnaires were subjected to regression analysis, multiple regression analysis, and Sobel's Z-test according to the research purpose with using SPSS 20.0. The research results are as follow. First, it was found that job performance, a sub-factor of childcare teacher personality, had an effect on child abuse. Second, it was found that the sub-factors of childcare teacher personality, humanity, creativity and personality, social relations, and job performance had an effect on job stress. Third, it was found that childcare activities, the sub-factors of job stress, and the relationship with parents had an effect on child abuse. Fourth, it was found that childcare activities, sub-factors of job stress, partially mediated between job performance and child abuse, a sub-factor of childcare teacher personality. These findings suggest that in order to prevent and contain child abuse by childcare teachers, specific plan must be actively prepared to improve job performance skills related to childcare teacher personality and reduce the burden of child care activities which is a sub-factor of job stress.

The study was conducted to identify the relationship between the e-cigarette smoking rate and demographic factors, health status and health behavior factors within the last one month of adults over 19 years of age, and to provide basic data for cessation education and health policy establishment to reduce the e-cigarette smoking rate. This is a secondary data analysis study using survey data of 22,908 people over the age of 19 who participated in the 2018 Community Health Survey in Seoul and the SAS program was used for analysis. Smoking rate of e-cigarettes within the last one month was 4.5%, and as a result of multivariate logistic regression analysis, factors related to e-cigarette smoking were sex, age, education level, occupation and general cigarette smoking status. In order to prevent e-cigarette smoking and reduce the smoking rate, education should first be given to professionals with educational backgrounds of college graduates or higher to inform the dangers of e-cigarettes. In addition, public relations and campaigns to inform the general public that e-cigarette smoking is no different from general cigarette smoking are required, and deployment of the same anti-smoking policy that treats e-cigarettes as general cigarettes is required.

Elderly suicide is a major public health issue in South Korea. The aim of this study was to systematically examine the current knowledge about suicidal ideation among Korean older adults with specific focus on risk and preventive factors. In order to achieve this aim, a meta-analysis was conducted using Korean academic peer-reviewed journals published since 2001. A total of 97 articles were selected that met the research criteria (e.g., original study findings and key words of suicidal ideation, suicidal thought, and suicide). Three domains were identified and used for further analysis: individual, family, and society. Results showed that among individual factors, depression and burden or stress increased the risk of suicidal ideation, while better mental health reduced the risk of suicidal ideation. Among family factors, living alone was a risk factor for suicidal ideation, while family cohesion was a preventive factor for suicidal ideation. Among social factors, elderly discrimination, social isolation, and negative relationships were significant risk factors, while social support, social environment, and social activities were significant preventive factors affecting suicidal ideation. The results suggest several practical implications for developing suicide prevention programs and counseling approaches to address suicidal ideation. For example, depression and stress can be reduced by MBSR (Mindfulness-Based Stress Reduction) program where meditation is used as a coping strategy. In addition, counseling programs specifically focused on improving family and social relations should be implemented. Government should continuously support for these programs to prevent suicide among older Koreans.

This study is aimed at articulating the policy communication concept and developing the policy communication index between the Korean government and the public. Theoretically guided by dialogic communication theory, two step research was employed. In the first stage, the elements of policy communication were derived through literature review and in-depth interviews. In the second stage, online survey was conducted for the general public and reliability and validity were secured through confirmatory factor analysis and structural equation model analysis. The finalized policy communication index has two dimensions of mutuality and openness. The mutuality has six sub dimensions and the openness has three sub dimensions. The level of mutuality and openness of the policy communication index differed according to the policy type. In the cultural policy, which represents the traits of distribution policy, the degree of mutuality was strong, but the degree of openness was important in communication of education policy, which represents the traits of redistribution policy. This study is meaningful as an empirical study that verifies and suggests the influence of the policy communication index in the context of the policy communication and practical applicability to strategic public relations by understanding the dimensions of policy communication.

This paper proposes to examine the relationship between the two trade unions of Hyundai Motor Company (HMC) - those of the regular workers and of the in-house subcontract workers - around the issue of converting irregular workers to regular ones, which has been a social issue for a long time, and, furthermore, to find a desirable solution. The politics of the in-house subcontracting rotate around three axes: the conflictive collusion between the company and the regular workers'union regarding the internal labor market; the exclusion and resistance between the company and the subcontract workers'union; and the solidaristic conflict relationship between the two unions. After the final decree by the supreme court in 2012 the conflict and collusion/solidarity relationship of the three social actors have been amplified in scale - the continuous limping of the special bargaining between the company and the unions, the intensified conflict between the company and the subcontract workers'union, and the crisis of the collusion between the branches of the two unions are all evidence of this. A clue to the solution to the issues of in-house subcontracting in HMC can be found through reestablishment of the relationship among the three actors. In order to solve the in-house subcontracting issues in HMC, phased and lawful switching from irregular to regular positions, improvement of working conditions for the irregular workers, integration of the two unions (realization of 'one company one union'), and negotiated flexibility in the internal labor market will be required. Also to be considered are installation of a special committee for the issue, and utilization of external consultants. The result would be the possibility for the corporate labor market of HMC to be composed of regular workers, legal contract workers and directly-employed contract workers, which could be realized through bilateral relations of 'the labor and management conflict partnership'.

This study compares and analyzes precarious labor market in Korea and Japan in terms of gender and occupational class. Previous studies have analyzed precarious labor limited to the level of employment type such as non-standard workers. This study reconceptualizes precarious labor in terms of the combination of employment relations and income level. In addition. we analyzed whether there are differences in the characteristics of precarious labor between Korea and Japan. In order to analyze the labor market precariousness in Korea. we used data from the 17th Korea Labor Panel Survey (2014) and for Japan. we used the 9th (2012) data from the Keio Household Panel Survey. As a result. we could confirm the feminization of labor market precariousness and horizontal division by occupation in both Korea and Japan. Also. ordered logistic regression analysis showed that the more women. and those in their 60s or older. the less skilled service workers. or the manufacturing workers are likely to face labor market instability in both Korea and Japan. The results of this analysis reflect the fact that Korea and Japan have experienced similar changes in the labor market structure with institutionalized employment protection system based on male workers.

This study focuses on the individual characteristics of consumers and creating shared value in relation to recent increasing value consumption. Specifically, it was intended to verify what socio-psychological variables of consumers affect value congruency and product purchase intentions in relation to cosmetics products based on creating shared value activities. In order to verify hypothesis, an online survey was conducted, and the main and mediate effects of the variables were verified through SPSS' Process Macro method. As a result of empirical analysis, the higher the ethical identity, altruism, and consumer effectiveness, the higher the value congruency. Altruism and consumer effectiveness had a positive impact on purchase intentions. We also find that value congruency has a significant mediating effect on the effect of socio-psychological variables on purchase intention. The results of this study provide practical values and implications for companies' need to emphasize consumers' consumption behavior as it can have a significant positive impact on society. It also suggests the importance of finding out what values consumers seek. In other words, this study can provide strategic implications for public relations plans when performing marketing activities by utilizing the values pursued by CSV in companies. Future research will provide strategic implications for promotional measures when marketing is carried out if the consumer's segment is further refined to verify the effectiveness of creating shared value.

This study aimed to identify the causes of adult cyberbullying, an issue which arouses little academic interest despite its seriousness and its harmful consequences, in order to provide basic data for the formulation of reasonable measures for preventing and reducing adult cyberbullying. To that end, the author of the study analyzed the results of the government-led Cyber Violence Survey conducted in 2019. First, the online survey panel owned by the research company selected a sample of 1,500 adult men and women in their 20s to 50s in proportion to reflect the composition of the local population. The survey was conducted online, with male subjects and female subjects accounting for 51.5% and 48.7% of the respondents, respectively. The result of the analysis shows that the respondents' attitude towards cyberbullying was fully mediaed according to such factors as gender, age, family relations, relationship with colleagues, Internet usage time, and contact with illegal content. In addition, partial mediation was observed with regard to online delinquency colleague numbers and cyberbullying victimization. As a result, the respondents' attitude towards cyberbullying was found to be the most important factor affecting adult cyberbullying. Based on these results, this study suggests that the formation of a non-conservative attitude towards cyberbullying should be considered to be more important than any other factors when preparing programs aimed at preventing cyberbullying.

There are unrestricted conditions on the driver's face inside the vehicle, such as changes in lighting, partial occlusion and various changes in the driver's condition. In this paper, we propose a face identification system in an unrestricted vehicle environment. The proposed method uses a near-infrared (NIR) camera to minimize the changes in facial images that occur according to the illumination changes inside and outside the vehicle. In order to process a face exposed to extreme light, the normal face image is changed to a simulated overexposed image using mean and variance for training. Thus, facial classifiers are simultaneously generated under both normal and extreme illumination conditions. Our method identifies a face by detecting facial landmarks and aggregating the confidence score of each landmark for the final decision. In particular, the performance improvement is the highest in the class where the driver wears glasses or sunglasses, owing to the robustness to partial occlusions by recognizing each landmark. We can recognize the driver by using the scores of remaining visible landmarks. We also propose a novel robust rejection and a new evaluation method, which considers the relations between registered and unregistered drivers. The experimental results on our dataset, PolyU and ORL datasets demonstrate the effectiveness of the proposed method.
