The present paper deals with the ordering problem for how to teach mathematical concepts successfully. Main object is the concept of continuous functions which is fundamental in analysis and topology. At first, the theoretical organization of this concept is investigated through several texts in related field, calculus, analysis and topology. And next, the historical order for this concept from the viewpoint of problem-solving is considered. Based on these two materials, we suggest a lecturing organization order in order to establish a balanced unification of three concepts - intuitive, logical and formal concepts.

The Purpose of this paper is to establish development strategies for sustainability of environment-Friendly agriculture based on farm awareness analysis. To analysis farm management, a series of farm household surveys were conducted on farmers residing in Embong-Myun. The sample size of the survey is 108 respectively. As a survey result, satisfaction level about market stability and understanding of upper organization is high, on the contrary, awareness of related organization is low in a relative sense. Most of farmers reveal their intention to sustain environment-Friendly agriculture but future agriculturalist and an ageing society that one face as well. In order to establish development strategies for sustainability of environment-Friendly agriculture, an infrastructure should be consistently expanded. On the other hand, self-supporting ability of farmer's organization and education system attempt to expand for sustainability.

In order to cope with the rapidly changing product development environment, individual manufacturing enterprises are forced to collaborate with each other through establishing a virtual organization. In collaboration, designated organizations work together for mutual gain based on product data interoperability. However, product data interoperability is not fully facilitated due to semantic inconsistency among product data models of individual enterprises. In order to overcome the semantic inconsistency problem, this paper proposes a reference ontology, Reference Domain Ontology(RDO), and a methodology for product data interoperability with semantic consistency using RDO. RDO describes semantics of product data model and metamodel for all application domains in a virtual organization. Using RDO, application domains in a virtual organization can easily understand the product data models of others. RDO is agile and temporal such that it is created with the formation of a virtual organization, copes with changes of the organization, and disappears with the vanishment of the organization. RDO is built by a hybrid approach of top-down using a upper ontology and bottom-up based on the merging of ontologies of application domains in a virtual organization. With this methodology, every domain in a virtual organization can achieve product data model interoperability without model transformation.

The organization effectiveness subi-items, such as job satisfaction, organization citizen's action, and organizational commitment are dependent variables. Sociodemographic variables are used for control variables. Findings are as follows: First, in terms of dental technicians' work ethic, the level of relation with coworker was the highest, and work centrality was the lowest. Second, in terms of dental technicians' organization effectiveness, the level of citizen's organizational action was the highest followed by organizational commitment and job satisfaction in order. Third, the effects of industry, work centrality, time save, relation with coworker, and morality showed statistically significant relationships with organizational effectiveness. Fourth, the effects of industry, work centrality, time save, relation with co-worker, and morality statistically significant relationships with job satisfaction. Fifth, in terms of organization citizen's action, the effects of industry, work centrality, and time save were statistically significant. Sixth, work centrality, time save, relation with coworker, and independence were statistically significant with organizational commitment. Conclusion: Some policy implications for the improvement of organizational effectiveness are introduced and discussed. Dental technicians are required to have vocation and work ethic for themselves and the organization, and by doing so, they may contribute to the improvement of national oral health. Policies and educational programs, which can support them may be necessary.

This paper suggests the measurement method of evaluation of management performance factors in health organization using AHP and Factor Analysis technique. To achieve this goal, this study applies AHP method to different size of hospitals. AHP method is deployed in three steps. At first step, the major factors, which indicate the management performance in health organizations, will be formed through factor analysis. At second step, the pairwise comparison between two factors will be performed to calculate the weights of each variables. At the last step, the order of priority of all factors will be determined. This order list will be used in measurement of the management performance in health organization. The results of this paper show that the financial factors take the top position, and followed by customer related factors, process factors and education & growth factors. This result could be the milestone for the measurement of management performance of medical organization in Korea.

The purpose of this study is to reduce the costs required to proactively prevent the turnover intention by the results of personality type of locus of control. which is the behavioral outcome of the members of the organization. Based on this problem consciousness, the present study focused on the personal characteristics of the members of the organization in the enterprise. Among the individual characteristics, the intentions, which are distinct from others, are called personality, Focusing on the locus of control among these types of characteristics of the organization members, the study about how these control positions affect their job involvement and their turnover intention. The results validated in this study are summarized as follows. Among the personality types of the organization's members, internals are found to have higher job involvement than externals. In addition, it was found that internals among the personality types of the members of the organization lower the meaning of turnover intention than external member. In order to overcome uncertain management environment and create and sustain a competitive advantage in the organization, management has a weight-oriented trend and Increasing job involvement in organizational members and lowering their turnover intention will lead to continued productivity, among other things, important management items that managers and managers should pursue. Given these aspects, it is deemed necessary to analyze the personality aspects of the members of the organization and to transform and manage a new management mindset that leads to the enhancement of the personality as an internal rather than an external one and the task immersion of the members of the organization based on it.

Self-organization of distributed wireless sensor nodes is a critical issue in wireless sensor networks (WSNs), since each sensor node has limited energy, bandwidth, and scalability. These issues prevent sensor nodes from actively collaborating with the other types of sensor nodes deployed in a typical heterogeneous and somewhat hostile environment. The automated self-organization of a WSN becomes more challenging as the number of sensor nodes increases in the network. In this paper, we propose a dynamic self-organized architecture that combines tree topology with a drawn-grid algorithm to automate the self-organization process for WSNs. In order to make our proposed architecture scalable, we assume that all participating active sensor nodes are unaware of their primary locations. In particular, this paper presents two algorithms called active-tree and drawn-grid. The proposed active-tree algorithm uses a tree topology to assign node IDs and define different roles to each participating sensor node. On the other hand, the drawn-grid algorithm divides the sensor nodes into cells with respect to the radio coverage area and the specific roles assigned by the active-tree algorithm. Thus, both proposed algorithms collaborate with each other to automate the self-organizing process for WSNs. The numerical and simulation results demonstrate that the proposed dynamic architecture performs much better than a static architecture in terms of the self-organization of wireless sensor nodes and energy consumption.

In this study, we used 170 copies of the 190 questionnaires from March 18 to April 20, 2018, except for 20 that can't be used as statistical value. The purpose of this study is to analyze the relationship between organizational entrepreneurship and social capital, organizational performance, and the relationship between entrepreneurship and social capital. The main implications of this study are as follows. First, the entrepreneurship of the executives recognized by the organization members has a positive influence on the social capital in the organization. In other words, the higher the entrepreneurship of management, the higher the social capital in the organization. Second, the effect of the entrepreneurship of the management on the organizational performance is shown to have a statistically significant positive effect. In other words, the entrepreneurship of management was a key factor in achieving organizational performance. Third, social capital in the organization has a statistically significant effect on organizational performance. In order to improve organizational performance, it is necessary to systematically improve and reinforce entrepreneurship and social capital in management. On the other hand, it is considered that the executives' entrepreneurial spirit consistent with the characteristics of the company type, management environment, and organizational members should be continuously demonstrated, and the implementation plan for the social capital in the organization should be developed. Therefore, high quality organizational performance for corporate sustainability management emphasized the importance of executive power on the systematic and continuous implementation of management entrepreneurship and the improvement of social capital for strengthening cohesion.
