Previous research on work and life balance mainly focused on workers' passive acceptance of interferences rather than active management of them. However, workers can also actively manage boundaries to enhance work and life balance. To find ways to enhance work and life balance, especially in the context of Smart Work, factors having effects on the work/nonwork interferences and their relationships should be firstly investigated. The results show that in a work domain, both boundary strength at work and job autonomy negatively influence on the nonwork to work interferences; in a nonwork domain, both boundary strength at nonwork and autonomy have negative effects on the work to nonwork interferences.

The goal of the research is to identify the relationship between organizational justice, job satisfaction, and work attitudes in the context of job rotation. The competence and loyalty of the employees of an organization are critical to the organization's success. Therefore, organization should invest in developing their employees, including creating effective procedures and human resource management policies. A job rotation program is one of the critical policies in developing employees, as through this program employees can develop and actualize their abilities. However, there are some challenges in practice regarding implementing the procedures of job rotation. One of the challenges is related to the concept of organizational justice, which then impacts on employees' job satisfaction and work attitudes. This study was conducted in focused group discussions. The sample is 272 of a state-owned organization. In this study, the concept of organizational justice, with the dimensions of distributive justice, procedural justice, and interactional justice, were used along with the discussion of job satisfaction and other work attitudes. The results were issues of fairness in perceiving organizational justice in the job rotation context, and the most significant response lies in procedural justice.

This article dealt with the formation and dissolution of tautological structure in the Frank Stella's work from 1959 to 1980 years by the analysis of signifier. A characteristic of Stella's work change is that it has the gradual progress which condensed into three periods -1) the formation and fixation period of tautological structure 2) the relaxation period of tautological structure and 3) the dissolution period of tautological structure. In other words, the early works of stella in the early 1960s has the structure which minimize differences in one hand, and maximize strictness, clearness, and identity on the other hand However, the stella's work from mid 1960s to mid 1970s extend differences gradually, while keeping a characteristic of prior work. And the stella's work after late 1970s has the decentered disintegration, namely anti-tautological structure which maximize differences. 'The formation and dissolution of tautological structure' in the Stella's work could be understood in relation to the fact that the Greenberg's modernist canon has loss the power gradually after late 1960s. That is to say, the dissolution of tautological structure in the late stella's work could be interpreted as the inevitable product which is produced in the searching for a new canon of painting. However, on the other hand, the structural change of stella's work in the late 20th Century is also understood in relation to the broader context, the social, and cultural context. Here, it is interpreted as the one of typical example which reflect a social and cultural convulsion designated as a 'Coming of Postmodernism'. In short, the late Stella's work which emphasize differences and unclearness, while diverging from early Stella's work which stress identity and rationality could be interpreted that it has the homology with the change of ways of thinking in the late 20th century Society.

For the policy makers and managers as well as the workers at work, it is important to identify what affects, to what extent, the safety level and costs of work sites. Within this context, the author analyzes fifteen construction work sites of the Incheon International Airport from 1996 to 1999 and shows that the expenditures for safety personnel and education programs contribute to reducing industrial accident costs. In addition, the author demonstrates that the regression analysis out-performs Heinrich method in estimating the accident costs of those work sites.

The purpose of this study is to discover the context and pattern of turnover social workers have experienced. To achieve this purpose, researchers collected data from in-depth interviews with seven social workers who have experiences of turnover and analysed the data using context-pattern analysis method. Research findings are composed of individual context-pattern analysis and integrated context-pattern analysis. In individual context-pattern analysis, researchers mixed time-dimension(before turnover/on the process/after turnover) and level-dimension(experienced phenomenon/meaning of experiences/context connected with phenomenon and meaning) and analysed the context of every stages and serial pattern. Also, we connected with each contexts and patterns and integrated the context-pattern of turnover. Integrated context-pattern structure is divided for four areas; organization before turnover, organization after turnover, social worker as a stakeholder of turnover, and network of social worker. Based on the results of the study, administrative recommendations were suggested in order to manage the turnover of social workers in social work fields.

Background: Urban bus drivers work under conditions that are among the most demanding, stressful, and unhealthy with higher rates of mortality and morbidity as well as absenteeism and turnover. Methods: Drawing on the job demand-resource model, this study investigates the impacts of job characteristics on emotional exhaustion and the effects of emotional exhaustion on job outcomes (including job satisfaction, life satisfaction, organizational commitment, and turnover intention) in the context of bus drivers. Results: Using self-reported survey data collected from a sample of 320 Taiwanese urban bus drivers, results reveal that role overload and work-family conflict (as job demand factors) positively relate to emotional exhaustion, and organizational support (as a job resource factor) is negatively associated with emotional exhaustion. Emotional exhaustion has negative effects on both job satisfaction and organizational commitment. Job satisfaction positively leads to life satisfaction, whereas organizational commitment negatively relates to turnover intention. Conclusion: This study concludes that role overload and work-family conflict as two stressors related to job demands and organizational support as the job resource factor to affect emotional exhaustion which further influence well-being in bus driver context. The moderating effects of both extraversion and neuroticism on the relationship between job demands and emotional exhaustion are evident.

Construction system modeling can enhance work performance by following the behaviors of a system. System behaviors may originate from physical aspects of a system, namely operation level variables, or from non-physical aspects of a system known as context level variables. However, construction system modelers usually focus on only one type of system variable (i.e., operation level or context level) which can lead to less accurate results. Hybrid modeling with System Dynamics (SD) and Discrete Event Simulation (DES) is one of the approaches that has been utilized to address this issue. In this research, an SD-DES hybrid model of a steel fabrication shop is developed, and the benefits of capturing context level variables together with operation level variables in the model are discussed.

The purpose of this study was to investigate how organization's ethical context, leader's agreeableness, conscientiousness and neuroticism affected his (or her) ethical leadership, and how leader's ethical leadership influenced subordinates' job satisfaction in the restaurant industry. The model was tested in hotel restaurants and family restaurants using a sample of employees in Pusan, Daegu and Gyeongsangbukdo. Empirical results confirmed that organization's ethical context, leader's agreeableness, conscientiousness and neuroticism influenced his (or her) ethical leadership, and leader's ethical leadership affected subordinates' job satisfaction. This research findings implied managerially that firstly, top management should establish employees' ethical regulations and motivate them to work ethically through training, incentives and punishment and secondly, should employee agreeable, conscientious and anti-neurotic person through aptitude test, if possible. In the future, restaurant's successful operations and management depends on partly its ethical status.

In order to provide customized services according to a specific user or environment, various service scenarios should be developed based on context-aware workflow model. As the context-aware workflow model is constructed using limited context information and service information in the service domain, overlapping elements can occur in many service scenarios. The repetitive work process that results from these overlapping elements delays the development process of the service scenario. Therefore, the elements of the context-aware workflow model must be reused to solve the unnecessary work processes of service scenario development. In this paper, we propose a reuse method XML Object in context-aware workflow model to improve the process of service scenario development. The proposed method documents and manages the independent XML Object of the context-aware workflow model and reuses it by invoking the unit document in the service scenario development process. It can also be applied to new service scenarios by changing the attribute values of reusable elements. Experiments show example that the development process of the service scenario is simplified by reusing the elements of the context-aware workflow model.

A video analysis system used to detect events in video streams generally has several processes, including object detection, object trajectories analysis, and recognition of the trajectories by comparison with an a priori trained model. However, these processes do not work well in a complex environment that has many occlusions, mirror effects, and/or shadow effects. We propose a new approach to a context-aware video surveillance system to detect predefined contexts in video streams. The proposed system consists of two modules: a feature extractor and a context recognizer. The feature extractor calculates the moving energy that represents the amount of moving objects in a video stream and the stationary energy that represents the amount of still objects in a video stream. We represent situations and events as motion changes and stationary energy in video streams. The context recognizer determines whether predefined contexts are included in video streams using the extracted moving and stationary energies from a feature extractor. To train each context model and recognize predefined contexts in video streams, we propose and use a new ensemble classifier based on the AdaBoost algorithm, DAdaBoost, which is one of the most famous ensemble classifier algorithms. Our proposed approach is expected to be a robust method in more complex environments that have a mirror effect and/or a shadow effect.
