본 연구는 2012년 12월 19일 한국대통령의 정치캠페인 기간 중 할당표본 추출된 시청율 패널 유권자 서울외 15개 지역 609명을 대상으로 설문하였다. 인게이지먼트 속성에서 후보자태도와 정책지지도, 유권자의 변수간 득표에 미치는 영향정도 등을 분석하였다. 분석에서 정치캠페인에서 정치관여도 고저에 따라 인게이지먼트의 속성에서 참여가 높다하여 반드시 정치후보자에 대하여 만족한 것은 아니라는 분석이다. 또한 인게이지먼트 속성 중 어느 인게이지먼트 속성이 높다하여 반드시 다른 속성에 영향을 주지 않는 것으로 분석되어 인게이지먼트 속성이 정치캠페인에서 상관관계가 없다는 해석이다. 그리고 후보자 태도와 정책지지도에서 인게이지먼트 속성 간 차이를 나타내고 있어, 후보자는 유권자에게 보다 신중하게 접근해야 할 것이다. 인게이지먼트의 속성에서 유권자들의 사호적변수인 성별, 지역별, 소득, 결혼여부에 따라 별로 차이가 없지만 연령과 학련 간에는 차이가 있는 것으로 나타나서 향후 정치캠페인에서 주요한 지표가 될 것이다.

Purpose: This study aimed to examine the relationship between organizational health (OH), safety climate (SC), the nursing working environment (NWE), and engagement in patient safety management activities (PSMA) among operating room nurses and identify the factors that predict engagement in PSMA. Methods: From August 10th to 25th, 2018, 176 operating room nurses who were working in tertiary and general hospitals responded to a structured questionnaire. Using SPSS/WIN 25.0, the collected data were subjected to independent-samples t-test, one-way analysis of variance, Scheffe?test, and Pearson's correlational and multiple stepwise regression analyses. Results: OH and SC were significantly correlated with engagement in PSMA. The factors that predicted engagement in PSMA were OH, NWE, participation in accreditation, years of work experience, and hospital size; together, they explained 17% of the variance in engagement in PSMA. Conclusion: This study revealed that OH has a significant influence on engagement in PSMA among operating room nurses. Therefore, hospitals should aim to create healthy working environments to promote engagement in PSMA among operating room nurses, actively delegate responsibilities to increase their level of participation in accreditation, and implement strategies that maintain high levels of nurse retention.

We consider a supply chain where products are shipped to warehouse from manufacturing system to customers. Products are supplied from either in-house regular manufacturing or the secondary source such as subcontractor. The inventory in warehouse is controlled by base-stock policy, that is, whenever a demand arrives from customer, an order is released to the manufacturing system. Unsatisfied demand is backlogged. The manufacturing system is modeled as M/M/s+1/c queueing system, and the orders exceeding the given limit care blocked and lost. The steady state distribution of the outstanding orders and the throughput of the manufacturing system are functions of the level of engagement In the secondary source. There is a profit obtained from throughput and cost not only due to the engagement of the secondary source in the manufacturing system but also inventory positions. We want to maximize the total production profit minus the total cost of the production system by simultaneously determining the optimal level of engagement of the secondary source and the optimal base-stock level of the inventory. We develop two algorithms : one without guarantee of the optimal solution but with the small number of computations, the other optimal but with more computations.

The paper examines the determinants of employee engagement in the not-for-profit organization (NFPO) sector. A structured questionnaire survey of 205 NFPO employees in Vietnam was employed, preceded by in-depth interviews with NFPO associates and managers. After a multiple regression analysis to study the impact of five independent variables on one dependent variable, the study reveals that Work design and Work-life balance are positively and significantly associated with employee engagement. Of which, Work design is measured by the level of job fit, job autonomy, job challenge, and job meaningfulness. On the other hand, Work-life balance involves measurement aspects consisting of how reasonable the workload is and organizational support. Meanwhile, different from the business world, Leadership, Learning and Development, and Recognition do not show statistically positive impacts on employee engagement in NFPOs. Still, they are crucial back-supporting factors to ensure employee experience at work. Further, the study finds that personal growth contributes a great part to keep employees in the sector motivated. This paper brings the area of study to the forefront in an effort to benefit the practice of human resources management in NFPOs as well as support employees in the sector with a higher quality working experience.

The study set out to identify the number of types of parental attitude profiles and their characteristics, as perceived by adolescents. The study also examined whether predictor variables (parent life satisfaction and self-esteem) influence parenting attitude profiles and whether these profiles, in turn, influence adolescent academic engagement and academic helplessness. The sample consisted of data on 2,590 adolescents and their parents from the 2018 Korean Children and Youths Panel Survey (KCYPS). The adolescents were in the first grade of middle school. Using Mplus, the author applied latent profile analysis to identify the parenting attitude profiles and predictor and outcome variables associated with these profiles. Three profiles were identified based on major features: (1) coercion-inconsistency (8.3%), (2) general (47.3%), and (3) warmth-autonomy support (44.4%). Parent life satisfaction and self-esteem predicted the classification of the profiles. Also, the parental profiles identified the level of adolescent academic engagement and academic helplessness. The findings have important implications for family policies and practices given the significance of parent psychological status, particularly life satisfaction and self-esteem, on their adolescent children's academic engagement and academic helplessness.
