컴퓨터도서 출판은 많은 문제점을 안고 있다. 저작권계약이 없는 외국 소프트웨어의 무단전재, 중복출판, 부적절한 번역출판에 따른 오류, 관련도서들의 발췌를 통한 짜집기 출판이 그런 예이다. 아래아 한글을 다룬 책이 43종이나 중복출판되고 있는 등 형식과 내용에 있어서 별 차이가 없는 출판양태 때문에 좋은 컴퓨터도서를 고르기란 쉽지 않은 일이다.

Facts, which constitute news, are as free as air. When they are transformed into news via labor and capital investment of a news organization, the news is deemed to have property values, and the media can claim exclusive rights over the news. The copyright law protects the originality of a work, the uniqueness of reporter's analysis, the selection of words, the arrangement of materials, and the emphasis given on particular points. The name of the game of copyright infringement lies in the infringement of the similarity of the method of expression, not the infringement of the subject. Even though news articles convey information by specifying factual elements of an event or accident, they still have some originality. The judgement that news articles lack of originality is inconsistent with the purpose of the copyright law. Therefore, the law should be amended to articulate that the unauthorized use of news articles without a proper citation shall be the subject of legal action, and courts should decide related cases accordingly.

The continuously variable transmission (CVT) of which speed ratio can change continuously in a fixed range has the benefits of low fuel consumption and exhaust gas because it enables the engine of a vehicle to operate in a high efficiency range regardless of vehicle speed. The speed ratio of belt type CVT is controlled by adjusting line pressure. The one of the line pressure control methods, mechanical-hydraulic control is usually adopting VDT's control method, in which the secondary solenoid valve has two functions both a regulator and a line pressure controller. However, this control method could not show the high performance of CVT with optimal driving capability because of the limitation of simple control algorithm, and it could not gain market share sufficiently in spite of the advantage of CVT with low fuel consumption. On the other hand, the electro-hydraulic control method gives the enhancement of power performance and low fuel consumption by implementing various driving mode using the proportional control or PWM control. The key of CVT technique is to develop a control algorithm of the electro-hydraulic solenoid valve in order to implement the speed ratio efficiently. In this paper, the line pressure control algorithm is proposed and the hydraulic system is controlled using metal belt type CVT test rig and the embedded ECU platform.
