Digital library in knowledge-information-based society of the 21st century should develop legally various digital information resources in order to provide information services to users. This study analyzes and examines in detail the related provisions of copyright law relating to the development of digital information resources(digitalized works, electronic books, electronic journals, electronic reserve materials etc.). This study also points out the problems of the current Copyright Act and proposed Copyright Act of Korea. And it suggests necessary measures and improved plans to promote the development of digital information resources.

The burst is to require abruptly high transmission rate in case of transmitting pre-stored variable bit rate video data, and it causes to be inefficient use of network resource, resource reservation. To avoid these problems, smoothing is transmission plan where variable rate video data is converted to a constant bit rate stream. These smoothing algorithms include CBA, MCBA, MVBA and others. To evaluate amount of burst reduction in the existing CBA, MCBA, MVBA algorithm, this paper compares the burst-related-factors of transmission plan in smoothing algorithms with original video sources which were stored Variable Bit Rate. There are maximum frame bytes, maximum GOP bytes, transmission rate variability per frame, transmission rate variability per GOP in burst-related evaluation factors. Experimental result shows burst-related factors of smoothing algorithms which were used for experiment lower than that of pre-stored video data, except special case.

ISDN is network which has been developed to integrate and transfer some information(data, video, voice). In the ISDN, security problem that threat and intrusion about important information resource increase because every information is transferred in the form of digital and access of network has patiency. In this paper, for protect important information resource, studied that apply application method and encryption system to ISDN, and system structure, ITU-T Q.931 protocol were analyzed, and proposable encryption key distribution protocol, call control with hybrid encryption system for user information privacy to provide security service.

As the city have been enlarged bigger and more complicated recently, a discussion about a city right, started on the base of perception that a city must be recognized as a public resource and the value. A city rights imply equal use and participation in these city resource. From a start of modern city, a city space have been developed mainly, as a man's economic business and industrial area, but now, to ensure a woman's city right is getting an important factor of citizen's settlement. Then many domestic cities tries to promote a woman friendly city creation. The main purpose of this paper is to find the concept of woman friendly city, based on a gender-sensitive perspective view point and to make an assessment index of Woman Friendliness of the City (WFC). In a case of Ansan City which city is in the planning stage of application for a woman friendly city.

This paper presents an advanced load control method in Direct Load Control(DLC) system. It is important to aggregate a various demand side resource which is surely controllable at the peak power time for a successful DLC system. Because the DLC system use simple On/Off control that may cause a harmful effect on a plant to reduce a peak power load, there are some restriction on deriving a voluntary participation of demand side resource. So it needs a new approach to direct load control method, and this paper describes an advanced load control method using control logic which is based on load properties. This method is easy to take account of a various characteristic of load, it can be use as a dynamic control logic which is good for adaptive control. The suggested control logic method is verified by modeling a control logic for a turbo refrigerator which affects on peak power in summer season.

In this paper the demand and supply of labor are forecasted over the next 10 years for customized nurturing human resource focused on Manufacturing Industry in Chung-Nam Province. Despite that the industrial structure is rapidly changing, industrial labors are nurturing on the basis of past industrial structure. This research is conducted for reducing mismatched labors throughout forecasting human resources until 2020. As a practical approach, the BLS Methodology is partially utilized. And the previous researches and official statistics data are reviewed. In conclusion, this study presents that more human resources on Manufacturing Industry than other Industries will be needed in Chung-Nam province. In details, it shows that there will be required more Industrial labors for strategic industries for examples, Audio and Video related industry, and Car related industry which is propelling by overall local government. In additions, policy implications are developed by analyzing current status and forecasting the labor demand and supply in the Chung-Nam Manufacturing sector.

This paper presents an efficient demapper architecture based soft-decision using the phase-section for Digital Video Broadcasting via satellite, Second Generation (DVB-S2). To achieve the satisfactory performance under a very low SNR conditions with the efficient hardware resource utilization, we propose a simple soft-decision demapper architecture using comparators to compare the phase of symbols and memories. The proposed architecture can decrease about 81% of the hardware resource, satisfying the BER requirements of DVB-S2. It has been thoroughly verified with an FPGA board and R&S(R)SFU (Rohde&Schwarz SFU-K108) broadcaast test equipment.

In this days, information resources are very important in the organization. So, Many public institutions as well as private companies eager to IRM(information resource management). Especially, one of core elements in this IRM is server's performance. Determinating server's performance is a big issue of an acquired organization. In this paper, we examine the key performance issue of server purchase and then we proposed the three measurement method of sever's performance that is considered environment of public sector.

Recently many documents have been written by HTML due to the expansion of the Internet and WWW. HTML allows scripting languages to interact between an user and an browser. Sometimes there might have problems with some functions of the script language. Some functions have the same name although the different contents and vice versa. It presents tremendous difficulties to maintain the functions. And, a file includes many functions shared among documents. If a user tries to see a HTML document, the file will be sent to the web browser in the user system. The network resource is wasted due to moving all data in the file through the network although some functions in the file is not used. So, we should design and implement the code library of a script language with a database. Each function has the name and arguments. A system of the code library manages functions with them. The system has the functions consistency and reduces the network resource consumption because there are only necessary functions in documents. Beside it is easy for the system to modify and reuse the functions.

In this paper, we propose the structure of multimedia file format based on MPEG-21 standard and the method to address a media resource within the file. The proposed multimedia file format supports the backward compatibility with MPEG-4 and the efficient addressing a media resource from a Digital Item that is XML-based MPEG-21 content. Also, the proposed multimedia file format can provide the functionality to package various types of media contents structurally and efficiently in digital broadcasting, Internet, and wireless environment. In addition, it can be a base model for multimedia file format that can be used for many different purposes such as integration and usage of metadata and multimedia contents.
