Quality management has been applied to the industry for strengthening the competitiveness regardless of the size of company. However, it has been argued that the operational models for quality management used in the large-sized enterprise could not be applied to the small & medium-sized enterprise (SME) directly. This paper analyzes the states and outcomes of movements for quality innovation in the SME and tries to give some suggestions for improving and spreading the movements within the framework of the cooperation with the large sized company. Survey results show that the preferable quality movements depends on the size of company. Especially, the Single PPM movement is most preferable in the SME. It contributes th decreasing the fraction defective and to vitalizing the communication and cooperation between large-sized company and SME.

In the modern society based on information and communication, which is exposed to the risks of a lot of information security breaches, corporate information assets may be an economical scale in a country. Most of damages derived from corporate technological information leak often occur in small and medium corporations. Although many information security managers in corporations have focused on certification systems such as information security management system, small and medium corporations are poorly aware of the information security, and their environments surrounding it should be also improved. In addition, it is difficult to expect spontaneous participations in it, since the sustainable information security management systems are often not forced to be certified. Thus, the purpose of this study is to examine plans to improve small and medium corporations' technological protections by using some component of the information security management system. On the basis of this examination, it also attempts to discuss some methods for effective and efficient information security in the small and medium corporations' technological protections.

The paper brings to question how image as a medium is becoming a replacement for traditional letters in the modern culture. Reflection the importance of image in the context of modern society with the changes in the values of communication. The importance of letters in its traditional format as a book that signified not only the method of communication but also power for those who governed during the days of illiteracy in the past has changed, in the beginning with the development of printing and today with movies etc. that supply endless images instead of words as a means of communication. The images are the next generation in the method of communication and can be noted from the earliest civilizations such as Egypt where the method of communication was not words but drawings that depicted specific significations. The use of images for communication purposes in light of this fact suggests that images was being used before words in societies and its communicative values greater than that of words.

This paper focus on a method to use Ethernet Network for Industrial Communication Network. Ethernet use the CSMA/CD MAC(Medium Access Control) Protocol at the Data-Link Layer, Which isn't suit for Industrial Communication Network requiring Real-Time Communication, periodic data processing, critical data processing characteristics. In this paper we proposed the Virtual Polling Algorithm at the Application Layer will be solution of using the Ethernet Network for the Industrial Communication Network, Proposed Algorithm terminate the Collision in the network thus Delay Time is reduced and Real-Time Communication will be implemented.

The fundamental conception in physics of the propagation of the electromagnetic wave polarization in matter is newly understood as the cardinal keyword in free-space quantum communication technology and cosmology in astrophysics. Interactive visualization of the propagation mechanism of polarized electromagnetism in a medium with its helicity has accordingly received attention from scientists exploiting the protocol of quantum key distribution (QKD) to guarantee unconditional security in cryptography communication. We have provided a dynamic polarization platform for presenting the polarization modes of a transverse electromagnetic wave, converting the state of polarization through the arrangement of optical elements, using Jones vectors calculations in Methematica. The platform graphically simulates the mechanism of production and propagation of the polarized waves in a medium while satisfying Maxwell's equations.

The objective of this study was to develop the classification method of various organic wastes. Specifically, the effects of proximate composition on the biogas production and degradation rates of agricultural by-production was investigated and a new standards for mixture of various organic wastes based on proximate composition combination was developed. Agricultural by-products (ABPs) with medium total carbohydrate, medium crude protein and low fat contents demonstrated the single step digestion process. ABPs with low total carbohydrate, high crude protein and high fat contents demonstrated the two step digestion process of Diauxic growth. The single ABP (Class No. 15) and the mixed ABPs (Class No. 12+18, 6+12+22, 9+12+18) after 10days showed the similar biogas yield pattern. We can use the classification method for the more ABPs and organic wastes from factory and municipal waste treatment plant for the high efficient biogas production.

In this paper, impedance characteristics of overhead medium-voltage (MV) power lines is reported for power line communication (PLC) over an MV power line network. For analysis, a two-port equivalent network model of MV power lines is derived. By applying the transmission line theory, reflection behavior and impedance of power lines are investigated. For verification, impedance of power lines is measured at a test field for an MV PLC. The results show that impedance of MV power lines is between $200{\Omega}$ and $300{\Omega}$ and converges to a half of their characteristic impedance.

This paper reviewed the relationship among safety education/managerial factors, safety motivation and safety appliance, and the moderating effect of safety motivation. Based on the responses from 225 employees in small & medium manufacturing and construction industry, hierarchical regressional analysis showed that all education/managerial factors have positive relationships with safety motivation. Also, safety motivation has mediating effect between education/managerial factors(safety education, communication, system, precautionary activity) and safety appliance.

A VPN is widely used in a communications environment which access is controlled to permit peer connections only within a defined community of interest. It is constructed through some form of partitioning of a common underlying communication medium, where this underlying communications medium provides services to the network on a non-exclusive basis. In this paper, we have analyzed a variety of architecture to implement Giga bps VPN system. The proposed architecture will satisfy the needs of clients who adopt Giga bps VPN system in the various environments.
