Composite coatings were prepared by co-depositing fine particles of metallic or non-metallic compounds with the metal matrix. With a newly developed nano powder, the nano particles strengthened composite coatings are increasingly attracting scientific and technological interest by virtue of their high hardness, lo friction coefficient and total inertness to any acid or other chemical attack. Among these ultra fine particles, ultra dispersed diamond particles are increasingly attracting considerable scientific and technological interest. However, commercially available powders of detonation nano diamond are complex conglomerates consisting of discrete levels of aggregation. In this work, experiments have been carried out to study the effect of ultrasonic treatment time on the mechanical properties and surface morphology of the electroless Ni-P/nano diamond(ND) composite coating. The results show that the nano-particles are uniformly distributed in the composite coating, and the microstructure of the composite coating is much finer and denser compared with the pure Ni plating.

This article aims to looking for the direction of the modern literature studies in the media convergence age. The critical situation facing literature today is related with changes in media as well as changes in society. Therefore, it is needed to find out which changes have been occurred in realism, modernism, postmodernism, and digital literature. First, when it comes to the attitude on understanding of reality, realism is strong for objective reflection on reality, modernism is strong for the inner world. Postmodernism is strong for constitutive reality, and digital literature is strong for virtuality or a fantasy. Second, writers have the absolute position in realism and modernism literatures, however, in postmodernism, readers hold prominent position over writers, and in digital literature, the writer-reader comes out. Third, the writings were canon in realism and modernism literature, and they changed to texts in postmodernism literature, finally they turn out hypertext in digital literature. As a result, digital literature breaking away from conventional text-literature, is regarded as exceptional literature or a new genre. Nevertheless, the studies on literature in the era of information society have no choice but to find out new direction. They require to expand the scope into the culture studies through humanities computing method and literature.
논문 : 무전해 Ni-W-P 도금에서 착화제의 종류가 피막특성에 미치는 영향
조진기 ( Jin Ki Cho ),박상욱 ( Sang Wook Park ),강성군 ( Seung Goon Kang ),손성호 ( Seong Ho Son ) 대한금속재료학회 ( 구 대한금속학회 ) 2008 대한금속·재료학회지 Vol.46 No.11
Deposition characteristics of electroless plated Ni-W-P films were investigated for various complexing agents. Used complexing agents are sodium citrate, sodium gluconate and sodium malonate. In this study, the existing mixed potential theory could explain the overall mechanism of Ni-W-P electroless plating for all complexing agents. The deposition rate could be also expected by the theory. The deposited Ni- W-P films were evaluated in term of surface hardness and corrosion resistance. Microhardness of the deposit increased about 1,000 Hv after heat treatment for one hour at 400℃, because it was above the crystallization temperature of Ni3P. The deposited Ni-W-P films can exhibit excellent corrosion resistance in using sodium malonate as a complexing agent, the other hand the using sodium gluconate was the worst corrosion resistance. The worst corrosion resistance was due to a large number of nano-sized pin-holes or small pores. The plating current at the mixed potential increases when the using sodium malonate as a complexing agent, it was explained by the cross section.

The 1940’s literature should be separately examined as the former term's and the latter term's. The literature of the former period was called as the dark ages of the Korean literature, as the end of the Japanese imperialism, however, the literature of the latter period played the important role in ideological conflicts, as well as reflected on the colonial era. Since the literature of the former period and that of the latter period were based on the different spaces each other, they should be studied separately. Therefore, in this study, the literature of the former period, the end of the Japanese colonialism will be examined. The literature of the end of the Japanese Imperialism was characterized as political works. As a result, the study on the literature in this period are able to make clear its characteristics, only when examined connected with the national policies in the end of the Japanese imperialism. The pro-Japanese literature in this period tends to be studied as following three views. The first view is to explain the meaning of the pro-Japanese literature and the characteristics of the works, the second view is to explain the characteristics of Manchurian literature, and the third view is to explicate the characteristics of the works written in Japanese. As the study of the pro-Japanese literature was started by Lim Jong-kuk, in 1966. it was put into shape by Chang Duk-Soon, Song Min-Ho, and Shin Hi-Kyo in the 1990's. In the 2000's, Kim Jae-Young, Ryu Bo-Sun took an interests in the notion and methodology of the pro-Japanese literature. The studies on Manchurian literature has been done by Kim Yoon-Sik, Oh Yang-Ho, and Cho Jin-Ki. The studies also revealed the feature of the Manchurian literature, only when connected with Japan's colonial rule of Manchuria. The works written in Japanese was studied by Kim Yoon-Sik and Rho Sang-Rae. However, the studies should have been focused on the directivity of the works, beyond the level of language expression itself. The pro-Japanese literature can be called as a national literature, in terms of inculcating the readers with the national policies of Japanese imperialism, and forcing to act. Therefore, the studies on pro-Japanese literature must show how the Japan's national policies to be expressed in the literary works. To do that, the criticism on the original texts should be done simultaneously.
