This study aims to suggest a new method to escape crisis of manufacturing industry. We focused on the field - oriented management innovation promotion performance divided into qualitative performance and quantitative performance. The site-centered management innovation is an organization that helps managers to quickly solve the problems faced by field management personnel by switching from manager-centered management method to on-site management personnel-oriented management. Find out the waste factors of the work and improve the process and set the process standards according to the customer's needs. Before working on the site, an employee should know exactly the process standard of what I will do, and frequently inspect the raw materials to make sure they meet the specifications. After the self-inspection is carried out, the standard is reviewed. If there is no abnormality, the cross-validation is carried out by the method which is carried over to the next step. The results of this study can be used to enhance the competitiveness of manufacturing companies. New management innovation techniques are required to adapt to the rapidly changing international business environment, and this study has implications for this research.

In recent years, Big Data has been a topic of great interest for the production and operation work of offshore plants as well as for enterprise resource planning. The ability to predict future equipment performance based on historical results can be useful to shuttling assets to more productive areas. Specifically, a centrifugal compressor is one of the major piece of equipment in offshore plants. This machinery is very dangerous because it can explode due to failure, so it is necessary to monitor its performance in real time. In this paper, we present stream data processing architecture that can be used to compute the performance of the centrifugal compressor. Our system consists of two major components: a virtual tag stream generator and a real-time data stream manager. In order to provide scalability for our system, we exploit a parallel programming approach to use multi-core CPUs to process the massive amount of stream data. In addition, we provide experimental evidence that demonstrates improvements in the stream data processing for the centrifugal compressor.

The purpose of this study is to investigate the effect of leader-member exchange (LMX) on envy and counterproductive behaviors (CWB) moderated by similarity. Specifically, we focused on the negative side of LMX to examine the relationship between LMX and envy, and the mediating role of envy on the relationship between LMX and CWB. Further, we also examined the moderating role of similarity on the relationship between envy and CWB. Given that CWB can be harmful to any organizational, it was worthwhile to find possible antecedents of CWB, envy and LMX. A total number of 238 employees participated in this study and the results supported our hypotheses. The results of this study can have managerial implications, showing the important role of manager's personalized treatment for each of his/her subordinates.

The development of unmanned AI continues, and the development of AI unmanned is aimed at more efficiently, accurately, and speedily the work that has been resolved by manpower such as industry, welfare, and manpower. AI unmanned technology is evolving in various places, and it is time to switch to unmanned systems from many industries and factories. We take this into consideration, and use the Deep Learning technology, which is one of the core technologies of artificial intelligence (AI), not the manpower but the fruits that pour the rails at once in a large orchard. We want to study the unmanned fruit sorting machine that can be operated under manager's supervision without dividing the fruit by type and grade and dividing by country of origin and grade. This unmanned automated classification system aims to reduce the labor cost by minimizing the manpower and to improve the

This paper presents vulnerability identification method based on meaning which is making use of the concept of atomic vulnerability. Also, we are making use of decomposition and specialization processes which were used in DEVS/SES to get identifiers. This vulnerability representation method is useful for managing and removing vulnerability in organized way. It is helpful to make a relation between vulnerability assessing and intrusion detection rules in lower level. The relation enables security manager to response more quickly and conveniently. Especially, this paper shows a mapping between Nessus plugins and Snort rules using meaning based vulnerability identification method and lists usages based on three goals that security officer keeps in mind about vulnerability. The contribution of this work is in suggestion of meaning based vulnerability identification method and showing the cases of its usage for the rule integration of vulnerability assessment and intrusion detection.

This study was conducted to suggest a direction in which safety managers can concentrate on industrial accident prevention and safety management for the organization. The job resources of safety managers were divided into organizational and individual levels, and the magnitude of the impact on organizational commitment was compared. Furthermore, job demands were classified into environmental risk factors and personal psychological factors to confirm their effect on organizational commitment. The moderating effect of job resources and sub-factors of the variable in the relationship between job demands and organizational commitment was verified. In this study, a questionnaire survey was conducted on 193 safety managers in the domestic electric construction business, data were collected, and a questionnaire of 180 people was used for the final analysis. Based on the results, organization-level resources among the sub-factors of job resources and individual psychological factors among the sub-factors of job demand had a more significant influence on organizational commitment. In the relationship between job resources and organizational commitment, the moderating effect of job demand was verified, confirming that job demand had a negative moderating effect. Individual psychological factors had a modulating effect, whereas environmental factors did not. The significance, implications, and limitations of this study are discussed based on the research results.

Due to the dense and complicated working environment, the construction industry is susceptible to many accidents. Worker's fall is a severe problem at the construction site, including falling into holes or openings because of the inadequate coverings as per the safety rules. During the construction or demolition of a building, openings and holes are formed in the floors and roofs. Many workers neglect to cover openings for ease of work while being aware of the risks of holes, openings, and gaps at heights. However, there are safety rules for worker safety; the holes and openings must be covered to prevent falls. The safety inspector typically examines it by visiting the construction site, which is time-consuming and requires safety manager efforts. Therefore, this study presented a worker-driven approach (the worker is involved in the reporting process) to facilitate safety managers by developing integrated computer vision and inertia sensors-based mobile applications to identify openings. The TensorFlow framework is used to design Convolutional Neural Network (CNN); the designed CNN is trained on a custom dataset for binary class openings and covered and deployed on an android smartphone. When an application captures an image, the device also extracts the accelerometer values to determine the inclination in parallel with the classification task of the device to predict the final output as floor (openings/ covered), wall (openings/covered), and roof (openings / covered). The proposed worker-driven approach will be extended with other case scenarios at the construction site.
