In the organization with a hierarchical network queue structure a production function is derived whose input factors are the numbers of servers at nodes and output is the number of served customers. Its useful properties are investigated. Using this production function, the contributions of servers to the number of served customers are studied. Also given an expected waiting time in the system for each customer, the optimal numbers of servers at nodes are obtained minimizing a cost function.

This study was to identify the concept of oppression in nursing organization thereby providing basic data on nursing education to improve oppression in nursing organization. Using Walker and Avant's criteria to identify attributes, antecedents, and consequences of oppression in nursing organization, 17 research articles published from 2006 to 2020 were reviewed. The defining attributes of oppression in nursing identified in this study were low self-esteem, lack of authority, and horizontal violence. The antecedents to oppression in nursing organization were oppressors, hierarchical organizational structure, and marginalization. The consequences of oppression in nursing organization included job satisfaction, organizational silence, patient safety and quality of nursing. Considering the findings, improvement of the hierarchical working environment in hospitals and self-awareness as professional nurses are important for nurses to overcome oppression in nursing organization. Therefore, effective educational programs should be developed to ameliorate working environment and self-awareness of nurses.

The purpose of this study is to analyze the characteristics and types of contemporary houses. This study deals with single-unit Korean houses designed by architects, which are included in architectural periodicals and books published since 1990. This study uses three analysis criteria: general characteristics of the house, hierarchical order of the plan and planning elements of houses. These criteria are derived from preceding studies and typological and topographical theories on houses. As the results of this study, the types of contemporary houses's plan are obtained from the perspective of plan's shape, hierarchical space relationship and spatial organization. Ten types corresponding to the plan shape are proposed. And eleven types of hierarchical space relationship are made and six spatial organization plan types are shown in this paper.

This study analyzed the effects of organizational culture on psychological empowerment and organization efficiency, and the effects of psychological empowerment on organization efficiency in fashion companies. In addition, this study analyzed the differences between organizational culture, psychological empowerment and organization efficiency across demographic characteristics. The survey was conducted among employees of fashion companies, and 320 responses were used in the data analysis. As a result, the group culture and innovative culture in fashion companies positively influenced the competence and meaning of psychological empowerment. An innovative culture and rational culture positively influenced the self-determination, and the group culture and rational culture positively influenced the impact of psychological empowerment. The group culture, innovative culture, and rational culture of fashion companies positively influenced job satisfaction, and the group culture, innovative culture, and hierarchical culture positively influenced job commitment. The group culture and innovative culture negatively influenced the turnover intention, but the hierarchical culture positively influenced the turnover intention. In addition, the psychological empowerment (competence, self-determination, impact, and meaning) positively influenced job satisfaction, and the competence, self-determination, and impact positively influenced job commitment. Competence negatively influenced the turnover intention, but the impact positively influenced the turnover intention. There was a difference in the group culture and turnover intention by ages, as well as a difference in the hierarchical culture and self-determination by work departments. The results of this study will be helpful for the establishment of the management and business strategies in fashion companies.

This paper develops a framework for efficient resource management within the grid service environment. Resource management is the core element of the grid service; therefore, GridRMF(Grid Resource Management Framework) is modeled and developed in order to respond to such variable characteristics of resources as accordingly as possible. GridRMF uses the participation level of grid resource as a basis of its hierarchical management. This hierarchical management divides managing domains into two parts: VMS(Virtual Organization Management System) for virtual organization management and RMS(Resource Management System) for metadata management. VMS mediates resources according to optimal virtual organization selection mechanism, and responds to malfunctions of the virtual organization by LRM(Local Resource Manager) automatic recovery mechanism. RMS, on the other hand, responds to load balance and fault by applying resource status monitoring information into adaptive performance-based task allocation algorithm.

The purpose of this study is to establish the relationship of empowerment and organization attachment with the organization culture of security organization. This study is based by setting the security organization employed in security firms in the capital area(Seoul) in 2012 as the parent population and using the purposive sampling method to analyze a total amount of 280 examples. The frequency analysis, analysis on primary factors, reliability analysis, multiple regression analysis, path analysis methods using SPSSWIN 18.0 were used in analysis. The reliability of the survey showed a Cronbach's ${\alpha}$ value of over 0.690. The results are like the following. First, the organization culture of security organization affect empowerment. Thus, the more a practical development culture is settled, the more the capability of self-determinism, meaningfulness, and effect is amplified. Moreover, the more a consensual culture is established, the more the capability of self-determinism is enhanced, and the more a hierarchical culture is established, the more the meaningfulness is enhanced. Second, the organization culture of security organization affect organization attachment. Thus, the continuous normative attachment is enhanced when a more hierarchical culture is established. Moreover, emotional attachment is enhanced when a more practical development culture is established. Third, the empowerment of security organization affects organization attachment. Thus, the continuous normative attachment is decreased when one's capability of self-determinism is more lacking. However, the continuous normative attachment is higher when the meaningfulness and effect is enhanced. Moreover, emotional attachment is enhanced when meaningfulness is increased. Fourth, the organization culture of security organization directly/indirectly affects empowerment and organization attachment. Thus, empowerment is an important mediating factor between organization culture and organization attachment.

The purpose of this study is to analyze the characteristics of hospital organization structure, organization culture, organization conflict and the interrelation of influential factor in organization conflict. The data for this study were collected through a self-administered survey with a structured delivered to 755 subjects including several nursing staff members, administration staff members and medical technicians at six hospitals. The structural equation model was used to examine the relation of organization structure, organization culture and organization conflict. The results of the analysis in this study were as follows. First, organization structure had a positive influence on organization conflict, especially in terms of complexity and centralization. But, formalization had a negative influence on organization conflict. Second, organization culture had a positive influence on organization conflict, especially in terms of group culture, developmental culture, and hierarchical culture. But, group culture had a negative influence on organization conflict. Third, organization structure had positive influences, especially on organization culture complexity, centralization, and formalization. But, centralization had negative influences too.

This paper presents a framework for the hierarchical PPC(Production Planning and Control) in make-to-order environment with job shop. The characteristics of the environment are described as : 1) project with non-repetitive and individual production, 2) short delivery date, 3) process layout with large scales manufacturing. 4) job shops. The PPC in a make-to-order typically are organized along hierarchical fashions. A model is proposed for the hierarchical job shop scheduling based on new concepts of production system, work and worker organization. Then, a new integrated hierarchical framework is also developed for the PPC based on concepts of the proposed job shops scheduling model. Finally, the proposed framework has been implemented in the Electric Motor Manufacturing and the results showed good performance.
