Interfaces are the point of interconnection between distributed generation and the energy infrastructure. These interfaces are generally physical but can include a market dimension as well. While there are issues surrounding various interfaces, the most important issues in the short term are on the electrical interface. Much of the discussion and debate surrounding distributed generation interconnection has centered on technical issues. However, there are two elements of Interconnection that merit equal consideration-process and contractual issues. The solution of distributed generation Interconnection issues depends on whether existing requirements can be modified to make them more efficient, transparent, and standardized while maintaining the grid's reliability and safety. In this paper, two main courses, standardization and third party participation, are suggested for the resolution of these issues.

The flight control law of developed flight control computer(DFLCC) is developed based on operation flight program of advanced trainer aircraft full scale development final configuration. The flight control law design is used common use development tool in GUI(Graphic User Interface) environment. The flight control law transformed to C-Code is reflected in OFP. The OFP is verified by the standardized verification process. But, before standardized verification process, we need preliminary verification process such as similarity of flight control law and reliability of developed HILS. Similarity of flight control law is verified by comparing the aircraft response of advanced trainer aircraft and those of the developed control law. Also, reliability of developed HILS is verified by comparing the aircraft response of HILS and Non-real time simulation result. This paper verifies similarity of developed control law and reliability of HILS environment as comparing aircraft response.

For efficient compatible system between medical clinics, the medical information has to be built on a standardized protocol such as a HL7 for text data and a DICOM for image data. But it is difficult to exchange information between medical clinics because the systems and softwares are different and also a structure of data and a type of code. Therefore we analyze a structure of DICOM file and design an integrated database for effective information sharing and exchange. The WISD system suggested in this paper separate the DICOM file transmitted by medical clinics to text data and image data and store it in the integrated DB(database) by standardized protocol respectively. It is very efficient that each medical clinic can search and exchange information by web browser using the suggested system. The WISD system can not only search and control of image data and patient information through integrated database and internet, but share medical information without extra charge like construction of new system.

The existing Europe Standard, EN 50159 with respect of safety of railway signalling communication protocol has been changed into International Standard, IEC 62280. This Standard presents the requirement for safe communication between safety-related devices which connects with transmission system, there are both closed and open transmission system. Regardless of this international Standards, the communication protocol for interface between CTC communication server and external facilities has been standardized several years ago in our country, so this is applied to integrated CTC system in KORAIL. Two Standards are currently standardized as a protocol between CTC and external facilities, these standard protocols are also required high level safety as a communication link which is transmitted vital control information in common with the train control system. For that reason, we have made analysis of requirement for the safe transmission required by international standard. Under this analysis, we have studied safety features of communication protocol applying to our standard. In other words, we have researched that how many the requirement from international standard for safe transmission is reflected in domestic standard protocol, and also whether our standard makes sure of safety enough or not.

The present study investigates a standardized framework for support system of ship design engineering. The purpose of this research is to improve the efficiency of information gathering and its use in tasks of the ship design engineering support system. Due to their variety and complexity, the existing engineering methods tend to waste time in searching for the standardized method and knowledge or to cause errors on tasks. Generally, these kinds of system have serious problems. The most serious one among them is that the existing system consists of both useful and useless data. This finally leads engineers to a failure in finding out useful information from the system. We have designed a standardized framework, which enables users to properly recompose the menu form depending on the task process, simplifies the methods at several process levels, and provides a more intuitive method in user interface environment in order to resolve the existing problems, minimize the system-operating costs, and improve the efficiency of engineering tasks.

With the increased development of 3D VR applications augmented by recent VR/AR/MR technologies and by the advance of 3D devices, interchangeability and portability of 3D data have become essential. 3D files should be processed in a standard data format for common usage between applications. Providing standardized libraries and data structures along with the standard file format means that a more efficient system organization is possible and unnecessary processing due to the usage of different file formats and data structures depending on the applications can be omitted. In order to provide the function of using a common data file and data structure, this research is intended to provide a programming binding tool for generating and storing standardized data so that various services can be developed by accessing the common 3D files. To achieve this, this paper defines a common data structure including classes and functions to access X3D files with a standardized scheme using the Python programming language. It describes the implementation of a Python language binding viewer, which is an X3D VR viewer for rendering standard X3D data files based on the language binding interface. The VR viewer includes Python based 3D scene libraries and a data structure for creation, modification, exchange, and transfer of X3D objects. In addition, the viewer displays X3D objects and processes events using the libraries and data structure.

Since 2000, the Ministry of Information and Communication has spearhead the so-called Knowledge Information Resource Management Project to turn South Korea into an information-knowledge powerhouse. With the project, the ministry has digitalized major information content in various fields such as history, education, culture and science, enabling many people to benefit through the Internet. During the period,12 institutions have participated in the history fields, The participants are as follows: Muncheongak at Gyeongsang National University, Ministry of Patriots and Veterans Affairs, National Institute of Korean History, Independence Hall of Korea, Korean Classics Research Insitute, Korea Democracy Foundation, Gyujanggak Archives, Seoul National University, Jongyeonggak, Sungkyunkwan University, The War Memorial of Korea, Korean Studies Advancement Center, Korean Women's Development Institute, and The Academy of Korean Studies. Because the 12 information systems have different functional user interfaces, it is confusing for people to utilize them effectively That requires us to standardize the interfaces, which would improve the overall improvement in effectiveness. This paper compares each user interface of the 12 information systems to determine their similarities and differences in terms of how to search information and present results. This work will pave the way to build a standardized user interface .

Wireless LAN(Local Area Network) environment to support QoS in IEEE802.11 Working Group has standardized on the IEEE 802.11e. IEEE 802.11e EDCA channel access of the high priority traffic as by raising the probability of a chance to support QoS. This is a high priority traffic than low priority traffic, channel access is not necessarily the first. Therefore, as all traffic channels, if you have the same routing path, lower priority traffic on the performance of high priority traffic, sustainable impact. As a result, EDCA, such as voice or video to guarantee QoS for multimedia applications, follow the crowd. In this paper, to solve these problems by using Multi-Interface Multi-Path Routing Algorithm is proposed. Interface for each use in IEEE 802.11e EDCA Access Category much differently by each of the Routing Path for high priority traffic and guarantee QoS.

We recognize call centers as a interface frequently interacting with clients, and as the first portal of enterprises promoting customer satisfaction and increasing the rate of customer maintenance. The importance of service quality in call centers is gradually enlarged, as criteria for competitive power of enterprises, and the first-line interface of communications with customers in operating method and business management. Also, Enhancing service quality is the first task of both the management and telemarketers in order to adapt to the customer's requirement level. The curriculum for telemarketer education is not established or standardized within the country yet. We must therefore study on it as soon as possible, though it has a short history and insufficient theoretics. In this paper, we descirbe the development of a formal telemarketer education program in call centers included the result that analyze existing educational programs, and the opinion of call centers.
