The construction industry causes the most accidents and fatalities among all industries. Although many efforts have been made to reduce safety accidents in construction, the study on the lost workdays that return to work place is insufficient. Therefore, this study proposes a model that classifies the lost workdays lost into moderate and severity, and derives the importance of variable and analyzes important factors through the trained random forest model. We analyze the learning process of the random forest which is a black box model, and extracted important variables that impact on the severity of the lost workdays through the extracted feature importance. The factors existing inside were analyzed through the extracted variables. The purpose of this study is to analyze the accident case data at the construction site through a random forest model and to review variables that have a high impact on the lost workdays. In the future, this sutdy can apply to improve construction safety management and reduce the accident of industrial accidents.

The main purpose of this research is to examine the relation of variables related to the worker's stress symptoms and coping. The influence of emotional support(from family, colleague, and boss), self-efficacy (self-regulatory, social, relational, resiliency, and management of work), job-satisfaction, and job-performance on worker's stress symptoms and coping is analyzed. Participants were 559 teachers (elementary 205, junior high 203, senior high 151; male 132, female 427). The results were as follows: There were no significant differences in stress symptoms and coping among primary, junior and senior high school teachers. On the other hand, there were significant differences in stress symptoms and coping between male and female teachers. Female teachers experienced more stress symptoms than male teachers. At the same time female teachers coped more efficiently in stress situation than male teachers. With emotional support, self-efficacy, job-performance and job-satisfaction as independent variables, the result of multiple regression showed that job-satisfaction has a negative influence on stress symptoms. Positive influences on stress coping was found for resiliency of self-efficacy in case of male teachers, and in case of female teachers resiliency of self-efficacy, emotional support from colleague, job-performance, and emotional support from family. Therefore, regardless of the gender of the teachers, high job-satisfaction decreased stress symptoms and high resiliency of self-efficacy increased efficient stress coping. As for female teachers, not only resiliency of self-efficacy but also emotional support from colleague and family, job-performance contributed to coping with stress.

현대 중소기업들은 기업 현장에서 각종 불필요한 경비의 지출이나 인력의 감원, 시간의 낭비 등을 위해 각종 개선활동의 참여를 독려하고 있다. 그러나 각종 개선활동에도 불구하고 그 효과나 영향력 등의 분석을 효과적으로 관리하지 못하여 지속적인 개선활동을 영위하지 못하고 있는 것이 현실이다. 이에 본 논문에서는 중소기업들이 현장에서 발생하는 각종 업무 및 시설 등에 관한 개선 사항의 건의 및 실행 활동 등을 관리할 수 있는 시스템을 제안한다.

본 연구는 기업과 그 기업이 속한 사회에서 사업을 영위하면서 자연재해의 발생이나 COVID-19와 같은 감염병의 유행으로 조직의 업무 중단이 발생하고 난 뒤 다시 사업을 재개하는 데에는 회복탄력성이 중요하다. 기업의 회복탄력성은 기업을 경영하는데 필요한 수많은 요소와 관련이 있다. 또한 기업과 연결된 많은 네트워크와 인프라에 의존하고 있다. 회복탄력성은 재난을 당한 뒤에 다시 사업을 영위하는 능력이라 할 수 있다. 재난에 대응하는 저항의 능력 보다는 기업의 핵심 기능이 단기간에 연속성을 확보하는데 그 의의가 있다고 하겠다. 이를 위하여 기업의 재난에 대한 '예방 활동', '대비 활동', '대응 활동'을 필수 요소로 삼고 있다. 그 외에 회복탄력성에 영향을 미치는 요인을 연구하기 위하여, 여유 자원, 협력관계, 전략적 유연성, 혁신성, 기술 변화 대응력이 조직역량에 미치는 영향력을 파악하고, 조직역량이 기업의 회복탄력성에 기여하는 정도를 파악하고자 하였다. (권재득, 2018). 회복탄력성의 미치는 추가요인인 외적 효과 분석에 대한 연구를 제안한다.

The purpose of this study is to explore the relationships between the empowerment, nursing performance, job satisfaction and turnover intention of long-term care hospital nurses. The subjects were 258 nurses at a long-term care hospital in B and U city. The data were collected from November 23, 2012 to January 21, 2013. Data were analyzed by SPSS win 20.0 program. The mean score of empowerment was 3.22, nursing performance was 3.78, job satisfaction was 3.25 and turnover intention was 2.87. Empowerment was correlated with nursing performance and job satisfaction positively, but correlated with turnover intention negatively. As a result of multiple regression, empowerment has 50.3% of the explanatory power on job satisfaction, 13.4% on nursing performance, and 21.9% on turnover intention. The significant predictive factors of nursing performance and job satisfaction were information and support in empowerment. In addition, turnover intention was resources in empowerment. These results suggest that empowerment improvement programs should be focused on developments to improve the quality of nursing.

This paper identifies the determinants of adoption of e-government services. The on-line tax filing and payment system, called Hometax, is a well-known e-government service for taxpayers. Using a theoretical model based on Technology acceptance model, this case study examines the causal relationships among the variables of the adoption behavior for on-line tax filing and payment system. Major research variables include satisfaction, perceived usefulness, perceived ease of use, words of mouth, subjective norms, trust, interaction and facilitating conditions. Results from 279 survey responses indicate that the usefulness and ease of use affect the user satisfaction, which, in turn, with the word of mouth influences intentions to use an e-government service. Subjective norms and trust has been found to affect the usefulness, and interaction as well as facilitating conditions have also some impact on the ease of use. As a conclusion, the academic and practical implications of these findings are discussed.

Based on the assumption that client violence against social workers may impede the effectiveness of social work intervention, this study investigated the prevalence and negative effects of client violence among child protection workers. A national sample of 207 child protection workers participated to the study. The results showed that 62.8%(n＝130) of the respondents experienced violence by children's parents or other guardians in the year of 2007. This prevalence was similar level to that of other service fields. However, perception about client violence of the respondents was more serious than workers in other fields. Respondents who have experienced client violence showed emotional reactions such as angry, burnout, frustrated. This emotional reaction impacted more on woman respondents. This study further found that client violence had negative effects on such work-related variables as workers job satisfaction and intention to leave.
