More addition of calcium carbonate in printing paper allows savings of the wood fibers and the drying energy. Pre-flocculation of GCC (ground calcium carbonate) using functional polymers was known as the best available technology to make high loaded paper until now, and it allowed less reduction of the paper essential properties such as tensile strength and smoothness at higher GCC content. However, pre-flocculated GCC became unstable in size under the continued agitation in the mill. Therefore, pre-flocculation method was modified in such a way that the in-situ calcium carbonate was formed between the GCC particles of the pre-flocculated GCC, and the resultant became more stable in size, which we named as HCC (hybrid calcium carbonate). HCC turned out to make high tensile strength and smoothness as much as the pre-flocculated GCC and gave much better size stability against stirring. Furthermore, HCC gave high bulk that pre-flocculation could not make.

인쇄회로기판에 솔더 페이스트를 인쇄하기 위하여 스테인리스 스틸 (Stainless steel, (i.e., SUS)) 재질의 솔더 페이스트 인쇄용 스텐실 마스크가 사용되고 있다. 하지만, 솔더 페이스트가 스텐실 마스크에 쉽게 달라붙기 때문에 솔더 페이스트에 의한 오염으로 인하여 생산성이 떨어지며, 스텐실 마스크 수명이 짧아지는 문제점이 발생되고 있다. 이를 해결하기 위하여 본 연구에서는 스텐실 마스크 표면에 소수성을 가진 고분자 코팅을 함으로써 솔더 페이스트가 쉽게 붙는 것을 억제하고자 하였다. 더욱 중요하게 스텐실 마스크에 전해연마 및 플라즈마 처리를 통한 표면 개질을 부여함으로써 고분자 코팅의 내구성을 향상시키고자 하였다.

Academic research libraries are seeking a long-term preservation plan for journals for cost-effective stewardship. The emergence of shared print archives has given the library community the opportunity to resolve the problem of the lack of library storage and build a collaborative long-term archiving plan for the print journals. The purpose of this study is to examine Western Regional Storage Trust(WEST), the largest print journal archiving program in North America, and identify their strategies for building a distributed, retrospective print repository service for journals. Based on the analysis, this article will discuss the development of new trends of collaborative library management in a digital age.

인쇄전자(printed electronics) 기술은 인쇄가 가능한 기능성 전자 잉크 소재를 이용하여 초저가격의 프린팅 공정을 통해서 다양한 전자소자를 제작하는 기술로써, 차세대 ICT 기기의 제작에 적합한 전자제품을 생산하는데 적합한 공정기술로 잘 알려져 있다. 현재 인쇄전자의 기술수준은 일부 요소 부품들을 제작하고 간단한 전자회로를 구현하는 수준에 머무르고 있으나, 도체, 반도체, 절연체의 여러 잉크 소재 및 다양한 초미세 인쇄공정 기술의 개발이 진행됨에 따라 향후 폭넓은 분야에 적용될 것으로 기대된다. 이러한 인쇄전자의 관련 기술 중에서 최근 삼차원(3D) 프린팅 기술이 부상하고 있는데, 지난해 Economist에서는 3D 프린팅을 제3차 산업혁명을 가져올 기술 중 하나로 소개했으며, 세계경제포럼(WEF: World Economic Forum)에서는 2013년 10대 유망 기술 중 하나로 선정했다. 올해 초, 미국의 오바마 대통령은 국정연설에서 거의 모든 제품의 생산 방식을 바꿀 수 있는 잠재력을 가진 기술로 3D 프린팅을 언급했고, Optomec에서는 전자소자용 3D 프린팅 기술을 선보였다. 본 논문에서는 최근에 많이 연구되는 모바일용 무선통신소자나 차세대 디스플레이 백플레인용의 인쇄전자 기술과 상품의 모형인 목업(Mock-up)을 제작할때뿐 만 아니라 전자소자 제작에도 적용이 가능한 3D 프린팅 기술에 대하여 논하고자 한다.

In this paper, we propose a printed planar antenna suitable for mobile wireless communications. Since the printed antenna is easy to fabricate due to simplicity, low cost, and light weight, it is widely used in communications systems. The conventional patch antenna takes too much surface area to be applied to a mobile receiver. Although the size is reduced using the printed antenna, still reasonably wide bandwidth should be considered. To overcome the disadvantage of narrow bandwidth, the substrate should be physically thick and the dielectric constant should be small. In this work, we suggest a simple form of printed planar antenna and show the optimal input impedance depending on the antenna size and operating frequency. The performance evaluation is achieved analytically for a prototype antenna model.

Printing process generates a vast amount of toxical waste and wastewater by the development of printing and publishing industry. The regulations for various environmental pollution material, which were indispensably used in printing industries, were getting stronger. The printing industries should develop the cleaner technologies in order to avoid the regulations. In this paper, the separation characteristics of microfiltration, ultrafiltration, reverse osmosis were surveyed to make basic data for the optimization of process as cleaner technologies for printing industries. The $2kg/cm^2$ of operation pressure were suitable to the U/F System. Because of the permeate of U/F was below 3 NTU as turbidity, which was probed to be possible using the rinsing water in printing process. U/F System,

Generally, printers are common for users to use for public use over a wired or wireless local area network. The number of printers in the same network is increasing, and management of multiple printers is needed. To do this, a program that drives two or more printers and a computer connected by a wired or wireless network. When a computer's control department receives a print command for a designated file, it executes the steps of receiving status information from the printer, selecting the printer, and sending the print command execution. As a method of research, we presented a method for selecting differentiation from this study through prior art research and literature research. Therefore, the purpose of the study is to distribute smart print commands according to real-time status information of many printers to increase the efficiency of the printer's management, and to distribute print commands according to the cumulative and usable workload of many printers so that parts replacement of many printers can be instantaneously performed.
