Legal deposit system is an essential tool for a national library to ensure the preservation and access to a nation's intellectual heritage over time. Substantial amounts of digital materials of national cultural value are already being published. There is a global trend towards extending legal deposit to cover digital materials in order to maintain comprehensive national archives. This paper gives a progress report of some countries around the world whose legal deposit laws have already updated or are under revision. Some strategies are suggested for the digital collection building of the Korean National Digital Library which will open in 2008.

The purpose of this study is to suggest guidelines for legal deposit process on online digital materials and use of the deposited materials both in National Digital Libraries and other places. At present, two Acts -- 'Act on Legal Deposit Process and Use of Online Digital Materials, ' 'Act on Partially Revised Library Law' -- are still pending in National Assembly. For the establishment of the guidelines in this study, advanced countries' legal deposit Acts in this area are searched and investigated. Also, in order to present various opinions from many parties immediately interested in the guidelines and Acts, survey, visitation, and consultancy methods are used.

Background: Human biological materials from cancer patients are linked directly with public health issues in medical science research as foundational resources so securing "human biological material" is truly important in bio-industry. However, because South Korea's national R and D project lacks a proper managing system for establishing a national standard for the outputs of certain processes, high-value added human biological material produced by the national R and D project could be lost or neglected. As a result, it is necessary to develop a managing process, which can be started by establishing operating guidelines to handle the output of human biological materials. Materials and Methods: The current law and regulations related to submitting research outcome resources was reviewed, and the process of data 'acquisition' and data 'distribution' from the point of view of big data and health 2.0 was examined in order to arrive at a method for switching paradigms to better utilize human biological materials. Results: For the deposit of biological research resources, the original process was modified and a standard process with relative forms was developed. With deposit forms, research information, researchers, and deposit type are submitted. The checklist's 26 items are provided for publishing. This is a checklist of items that should be addressed in deposit reports. Lastly, XML-based deposit procedure forms were designed and developed to collect data in a structured form, to help researchers distribute their data in an electronic way. Conclusions: Through guidelines included with the plan for profit sharing between depositor and user it is possible to manage the material effectively and safely, so high-quality human biological material can be supplied and utilized by researchers from universities, industry and institutes. Furthermore, this will improve national competitiveness by leading to development in the national bio-science industry.

After the establishment of the Korean Government in 1945, we were busy building up library collections, especially expanding the quantity of books. As a result, nowadays we witness the problem of limited space to keep the books. Space is one of the most important factors in the environment of library materials preservation. To solve this problem, we have to establish many levels of deposit library. The deposit library functions to preserve library materials. Preservation is defined as 'preservation', 'conservation' and 'restoration'. Deposit library was not for circulation that established in the Korea Dynasty, was succeeded by the branch libraries for Historical Deposit Libraries and branch library of Kanghwa magistracy of Kyujang-gak in the Chosun Dynasty. This study is to analyze the establishment, the activities and functions of the branch library of Kyujang-gak at Kanghwa Magistracy as a deposit library. Hence this study provides valuable information for future research of the history of deposit libraries in Korea.

This study was conducted to investigate the materials deposit policies and service policies of overseas collaborative repositories and provide practical data that can be referred to the management of the collaborative repository in Korea. For this purpose, this study tried to analyzed websites of 7 collaborative repositories and related data. Materials deposit policies were focused on duplicate materials, criteria of materials to be accepted, ownership and withdrawal and service policies were focused on on-site services and off-site services including circulation and document delivery service(electronic copy and photocopy). The results of this study can be used as practical data for the establishment of guidelines for collaborative repository in Korea.

Stellite 12 alloy-powder was overlaid on 410 stainless steel valve seat using plasma transferred arc(PTA) process. Variation of characteristic of microstructure and hardness of deposit with current(90~150 A) and preheat temperature(R.T.~$400^{\circ}C$) was investigated. Important conclusion obtained are as follows; All welding conditions used produced a sound deposit layer with no defect in single pass welding. The maximum deposit had 4.0~4.8 mm in thickness and its bead width was increased with increase of current and preheat temperature. The deposit showed hypoeutectic microstruture, which was consisting of primary cobalt dendrite and networked $M_7C_3$ type eutectic carbides. The amount of eutectic carbides was decreased and its dendritic secondary arm spacing was increased with increase of current. Hardness of the deposit was decreased with increase of current. Preheat temperature up to $400^{\circ}C$, however, showed little influence on the hardness and microstructure. The hardness was also influenced by diluted Fe content near the interface in addition to microstructure and dendritic secondary arm spacing. Hot hardness at $500^{\circ}C$ showed higher than 300 HV.

A miniaturized lab-scale Cu plating cell for the metallization of electronic devices was fabricated and its deposit uniformity and profile were investigated. The plating cell was composed of a polypropylene bath, an electrolyte ejection nozzle which is connected to a circulation pump. In deposit uniformity evaluation, thicker deposit was found on the bottom and sides of substrate, indicating the spatial variation of deposit thickness was governed by the tertiary current distribution which is related to $Cu^{2+}$ transport. The surface morphology of Cu deposit inside photo-resist pattern was controlled by organic additives in the electrolyte as it led to the flatter top surface compared to convex surface which was observed in the deposit grown without organic additives.

Cold spray (Cold gas dynamic spray, kinetic spray) is the latest spray coating process that is known as solid state deposition process. In cold spray, inert gases (typically nitrogen and helium) accelerate powder particles prior to impact onto the substrate. Accelerating particles start to deposit onto the substrate after reaching certain critical velocities depending on the coating materials and substrate. Since process gas temperatures are kept below to melting temperature of the coating materials, it is possible to spray temperature sensitive materials such as copper and titanium, nanocrystal materials, and amorphous metals without affecting the phase change and oxide formation. It is also possible to deposit thick coatings because cold spray coatings present compressive residual stresses. This ability to deposit thick coatings is suitable to repair or rebuild parts as an additive manufacturing process. In this presentation, cold spray is introduced and compared to other additive manufacturing processes such as laser and electron beam based processes. It is also presented some applications especially in the view point of additive manufacturing process.

In digital environment the hallmark of the national libraries is its responsibility or function of acquiring and preserving the county´s off-line and on-line publications in term of legal deposit. But the legal deposit system based on print materials in Korea predates the digital age and requires a new legal framework. It would be a tragedy if national library was not to archive the nation´s intellectual and cultural heritage because of limitation of legal deposit system. The purpose of this paper is to analyze form of the current deposit system and to suggest a reform model for legal deposit legislation with priority given to legal scheme and elements(terms, the depositor, the depository, object of deposit, number of copies, time of deposit, compensation and fine, right of migration and free access, etc.).
