본 논문에서는 비월 주사 영상을 하나의 필드만을 사용하여 순차 주사 영상으로 변환시키는 투표 결정 기반 디인터레이싱 보간방법(VDD)을 제안한다. VDD는 투표 결정 방법을 이용하여 4단계 보간 과정을 거치게 된다. 1단계는 MM-ELA방법을 이용하여 거짓 에지 의심영역을 검출하는 과정이다. 검출된 영역은 상위 주변 화소 정보를 이용한 다수결 투표 결정 방법인 2단계 과정으로 에지 방향을 결정하며 미결정 방향은 3단계 과정인 상, 하위 주변 화소 정보를 이용한 다수결 투표 및 방향성 평균으로 에지 방향을 보존하고 화질 열화를 최소화한다. 마지막으로 위 단계에서 결정되지 못한 화소는 세밀한 방향을 고려할 수 있는 DOI를 이용하여 보간한다. 계층 구조의 VDD는 복잡도가 높지만 계조도 변화에 취약한 기존 방법들에 비하여 정교한 에지를 추출할 수 있으며 실험결과를 통해 객관적, 주관적 우수성을 나타낸다.

This study reviews several innovative electronic reference services that will be transformed in the age of the virtual library. This study focused on reference service via E-mail and electronic bulletin board which is regarded as the most important service in a variety of electronic reference services. Through E-mail and the electronic bulletin board, the user submits questions and the librarian responds with the answer. Though interest in using E-mail and electronic bulletin board as a basis for reference service has grown considerably in recent years, it is still in its infancy in Korea. Thus the purpose of this study is to propose a model electronic reference service system using E-mail and the electronic bulletin board for university libraries in Korea. This system consists of the following modules: electronic reference services policy, open reference service via electronic bulletin board, closed reference service via E-mail, and FAQ. This system is meant to be a guide for those considering implementing such a service.

The properties of LTCC green tape with addition of binder were investigated in order to understand an effects of binder on multilayer processing. A green sheet form was fabricated through tape casting method with the MLS-22 powder. The lamination density increased with increasing amount of binder and lamination pressure. With increasing amount of binder, the elongation of ceramic sheets increased but the tensile stress and air-permeability decreased. The addition of excessive binder is caused defects in the green sheet during via hole punching. The optimum condition of the via hole without defects was observed from amount of the binder 10 wt%.

Due to its unmanned feature and some of being matured underwater technologies, UUV(Unmanned Undersea Vehicle) is increasingly considered as a utility player in today's battle-field. The operational benefit of submarine-based UUV operation could be enormous yet the integration challenges are significant, particularly for most of small conventionally-powered submarines. In this paper, we consider UUV operational methodology via the conventional submarine's torpedo tube. Two previous attempts having been done to retrieve the UUV through torpedo tube are reviewed, and their pros and cons are also analyzed. Then, an alternative option is proposed for UUV operation via torpedo tube. In addition, some of practical challenges are also discussed in the paper.
