탄성파 지연선의 진동자에서 전단과 지연매질사이의 접착제의 두께를 고려하여 변환손실을 계산하는 방법을 제안하며, 수치계산결과 접착제의 두께가 진동자 두께의 1/100정도 이하로 하여야 하며 전극의 두께가 진동자 두께의 1/10정도 될 때 중심주파수의 이동이 생진다. 접착제의 두께를 진동자와 거의 같거나 그 이상으로 하면 주파수 대역폭에서 현상이 점점 커지게 된다. In this paper, the methode of calculating conversion loss is proposed by considering the thickness of bonding medium between electrode and delay material in the vibrator of Elastic delay lines. As the result of computations using digital computer, it is shown that the thickness of bonding medium must be less than about 1/100 of the thickness of vibrator and when the thickness of electrode is about 1110 of vibrator, the center fnequency is shifted. When the thickness of bonding medium is equal to or more than the thickness of vibrator, the 리uctuations in frequency Bandwidth become larger and larger.

Marbling dyeing technique shows beautiful flowing pattern because the pattern is transferred to the medium by the pigments floating onto the viscous solution base. However, this marbling pattern does not have any reproducibility and the result of accidental pattern formation. Marbling process contains many complicated procedures such as making marbling base, mordanting the medium, and bubble removal with size limitation. Computer changed the many aspects in textile design and digital technique is used in many design production. However, it is impossible to produce marbling pattern with digital drawing. In this research, the digital textile design starting from marbling pattern was developed for digital textile printing. Marbling was done to produce the initial motifs and scanned. Several marbling media such as silk, polyester, and paper were used. Photoshop was used to process and develop textile design based on these marbling motifs. One repeat was developed and various colorways were tried. The developed textile design were printed using DTP.

Introduction of digital broadcasting service does not only mean the change of information transmission method but also the change of total broadcasting system. In past day, Television was only received one-sided information from broadcasting station, but digital broadcasting means that digital television becomes the most important means of information transmission by the introduction of new programming, lots of channels, data service, multi communication. In the age of the digital broadcasting, the recording and replay medium's interest is getting higher. The medium is able to record more than 24 hours' digital broadcasting programs without additional tapes. In this paper the recording and replay device using HDD was implemented and device driver based on linux was programmed. It has Intel PXA250 processor and hard disk is used as storage equipment. And transport Stream is saved on hard disk through PXA250's data bus. FIFO is added to solve the different saving speed and FPGA is also added to display the saved data.

본 연구는 정보화 분야에 있어서 우리나라 중소기업이 처한 일반적 상황 속에서 부산지역 중소기업의 위치를 확인하고 그에 대한 시책의 현황 및 실태 그리고 시책에 대한 수요자의 태도를 분석하였다. 분석결과, 부산은 전자상거래율을 포함하여 전국 평균 이하로 나타났다. 국내 총생산에서의 부산경제 비중을 고려할 때 부산지역의 중소기업 정보화 격차는 시급히 개선되어야 하는 과제이며 더욱 심각한 점은 제조업의 정보화 격차이다. 따라서 제조업 정보화 지원시책의 활성화와 현행 생산기술 정보화 지원사업의 확대가 필요하다고 보인다. 또한 문제해결과정에서 부산광역시도 적극적으로 자기 역할을 찾아야 할 것으로 보인다.

The purpose of this study is to analyze the impact of quality management system requirements, which are techniques for management innovation to secure competitiveness of small and medium-sized manufacturers, on management performance as economic uncertainties increase and non-face-to-face culture spread. To this end, a survey was conducted on small and medium-sized manufacturing companies that maintain ISO certification. As a result of the study, first, it was found that planning had a positive effect on management performance among the requirements of the quality management system. Second, it was found that improvement among the requirements of the quality management system had a positive effect on management performance. Third, in the relationship between the requirements of the quality management system and management performance, leadership was found to have a complete mediating effect on planning.

In the modern society based on information and communication, which is exposed to the risks of a lot of information security breaches, corporate information assets may be an economical scale in a country. Most of damages derived from corporate technological information leak often occur in small and medium corporations. Although many information security managers in corporations have focused on certification systems such as information security management system, small and medium corporations are poorly aware of the information security, and their environments surrounding it should be also improved. In addition, it is difficult to expect spontaneous participations in it, since the sustainable information security management systems are often not forced to be certified. Thus, the purpose of this study is to examine plans to improve small and medium corporations' technological protections by using some component of the information security management system. On the basis of this examination, it also attempts to discuss some methods for effective and efficient information security in the small and medium corporations' technological protections.
