This research aims to suggest a practical solution in order to make marriage immigrant women free from violence and stand on their own. The suggestion could be made by developing Substantive theory in terms of marriage immigrant women's coping with domestic violence. The research question is; How marriage immigrant women cope with domestic violence. The research used a route theory approach, and 11 of marriage immigrant women who have ever suffered from domestic violence participated in it. The research question used semi-structured open questions. As a result of paradigm model analysis, "mental and physical devastation" is defined as a core phenomenon, and causative conditions are "wheel of pain" and "helpless victims of violence". Besides, context conditions are "period growth with solitariness", "irrational marriage" and "indifferent reality". "Mental and physical devastation", the core phenomenon act and interact with effect of mediatory conditions; which are "social help", "cultural difference" and "helplessness". Here the action and reaction appear as "adaptation", "resistance", "self-protection" and "self-reinforcement", and the outcomes show up as "maintaining reality", "decision making" and "beginning a new life". "Coping with mental and physical devastation and standing on one's own feet" could be introduced as a core category. Process of coping with domestic violence presents its levels as; shocks ${\rightarrow}$ endurance ${\rightarrow}$ regret ${\rightarrow}$ overcoming. There are three patterns of coping, which are; "preserving realities", "returning", and "groping for the future".

The down-core distribution of chlorophyll a, organic carbon contents and ${\delta}^{13}C$ in the bottom sediments were measured to understand the evolution of eutrophication in Masan Bay. Bottom sediment were collected in January 1994. The chlorophyll a and organic carbon contents in the sediment core decreased with increasing sediment depth, respectively. Bottom sediments (0~20 cm) in Masan Bay was rich in chlorophyll a (avg. 9.6 ${\mu}g\;g^{-1}$ dryweight) and organic C (avg. 2.5%). The down-core distribution of chlorophyll a suggests that the inner part of Masan Bay has experienced the acceleration of chlorophyll a supply since 1960s. Flux of organic carbon to the sea floor is in the range of 10 $gCm^{-2}\;yr^{-1}$ assuming the C:Chl a ratio of 25. It suggests tht approximately 1.3% of the fixed carbon by phytoplankton appears to be deposited in the bottom sediments.

This study was carried out to exploit and utilize the exotic American Sycamore(Platanus occidentalis) grown in Korea as a veneer species for plywood manufacture. At present most parts of veneer Legs used in Korea were depended entirely upon the gonus Shorea woods(lauan logs) imported from Southeast Asia region. To decrease manufacturing cost and save imported lauan veneer logs, the effects on properties affecting to the six types of plywood made from proper veneer constructions composed by domestic American Sycamore and imported lauan veneers were compared and discussed. The study has important meanings for the promotion of plywood manufacture by domestic materials. Important items dealt with this study were dry and wet shear strength, moisture contents, specific gravties, and bending strength. By the results and discussions it may be summarized as follows: 1) In dry shear strength platanus(sycamore) core lauan plywood was shown most excellent strong results, and next orders were all lauan plywood, platanus faced lauan plywood, lauan core platanus plywood, lauan faced platanus plywood, and all platanus plywood. There was no difference between platanus core lauan plywood and all lauan plywood, but the differences between those plywoods and the other types of plywood were recognized. 2) In wet shear strength platanus core lauan plywood was shown excellent result the same as dry strength. The difference between platanus core lauan plywood and the other types of plywood was shown, but among the other types of plywood except platanus core lauan plywood were not recognized. 3) The differences among moisture contents according to the veneer construction were not recognized. 4) The plywood constructed by two or more sheets of lauan veneer was shown lower specific gravities than the plywood constructed by two or more sheets of platanus veneer. It is believed that this tendency due to the original specific gravities of veneer before construction. 5) The differences among specific gravities of lauan core platanus plywood, all platanus plywood and lauan faced platanus plywood were not recognized, and like this analyzed result among platanus core lauan plywood, all lauan plywood and platanus faced lauan plywood were not recognized. Accordingly it is believed that the differences are not shown among the plywood constructed by two or more veneers of same species. 6) In bending strength platanus core lauan plywood was shown most excellent values. Next orders were all lauan plywood, platanus faced lauan plywood and the other types of plywood. The differences among the plywood constructed by two or veneers of lauan were shown, but not shown among the plywood constructed by tow or more veneers of platanus.

Recently, digital rights management (DRM) related researches are widely spreading with prosperity of IT industries. The DRM technology protects proprietor of copyright by preventing mischanneling and illegal copy. In this paper, we propose a new DRM model that has an enhanced and efficient protocol based on certificate using smart card. The proposed model overcomes weaknesses of WCDRM model and has following additional advantages: first, copy protection is enhanced by hiding user's specific information from attacker by storing the information within smart card; second, server load for contents encryption is reduced by making clear protocols among author, distributer, certificate authority, and users; third, offline user authentication is guaranteed by combining partial secret values in media players and smart card. Exposure of core information also is minimized by storing them in smart card. In addition, we show that the proposed system is more secure than WCDRM model by comparing various factors of anonymous attackers.

In this paper, we implemented an Elliptic Curve Cryptography(ECC) processor for Digital Transmission Contents Protection (DTCP), which is a standard for protecting various digital contents in the network. Unlikely to other applications, DTCP uses ECC algorithm which is defined over GF(p), where p is a 160-bit prime integer. The core arithmetic operation of ECC is a scalar multiplication, and it involves large amount of very long integer modular multiplications and additions. In this paper, the modular multiplier was designed using the well-known Montgomery algorithm which was implemented with CSA(Carry-save Adder) and 4-level CLA(Carry-lookahead Adder). Our new ECC processor has been synthesized using Samsung 0.18 m CMOS standard cell library, and the maximum operation frequency was estimated 98 MHz, with the size about 65,000 gates. The resulting performance was 29.6 kbps, that is, it took 5.4 msec to process a 160-bit data frame. We assure that this performance is enough to be used for digital signature, encryption and decryption, and key exchanges in real time environments.
