본 논문에서는 실제 통신망에서 발생할 수 있는 데이타 전송과정을 컴퓨터상에 시뮬레이션하는 프로그램으로서, PC의 WINSOW 환경하에서 Visual-Basic을 활용하여 통신신호의 흐름과정을 하나의 화면에서 구현하도록 부호화와 변조파형을 표현하고 이 신호의 복조와 복호과정을 시뮬에이션한다. 아울러 통신채널에서 발생하는 랜덤오류를 제어하는 오류정정을 포함함으로서 통신이론을 이해하고 학습하는데 많은 도움이 될 수 있도록 통신신호에 대한 그래픽 처리에 목적을 둔다. In this thesis, the graphic signal for communication is presented in the WINDOW using `Visual-Basic'. All signals of PCM encoding/decoding and modulation/demodulation are processed in the same picture. Especially, error control schemes which are parity check, longiudinal redundancy check, cyclic redundancy check, are described for more reliable communication.

Purpose: There have been no studies employing a specific questionnaire relating to patient satisfaction following ambulatory hernioplasty. Via the production of a novel specific questionnaire, attempts were made to determine the factors associated with patient satisfaction following hernioplasty on an ambulatory basis. Methods: Patient satisfaction was evaluated via cross-sectional telephone surveys administered 10.5 (range of 2∼23) months after their operations, consisting of six questions, regarding; anesthetic technique, surgical method, necessity for admission, necessity for follow-up, intraoperative pain, and postoperative pain. Each of the questions was then scored using a 4-point scoring system, with global satisfaction determined via the addition of each score. Factors related to global satisfaction were determined among preoperative, intraoperative and postoperative factors. Results: Telephone questionnaire interviews were conducted on all 131 consecutive patients. Four respondents (3.1%) expressed dissatisfaction with the ambulatory surgery. Twelve (9.2%) had been admitted overnight after the operation. Thirteen (9.9%) required analgesics for over 3 days. No patients required a re-operation, although 20 (15.3%) experienced minor postoperative complications. Significant factors for global dissatisfaction were analgesic requirement for over 3 days and the presence of surgical complication (P value <0.05). Time until return to work and required overnight admission were important factors for patient satisfaction, but these were not significant. Conclusion: Patient satisfaction was associated with postoperative pain and surgical complications. Therefore, a more appropriate method for pain control and prevention of minor surgical complication are suggested might serve to enhance patient satisfaction after hernioplasty on an ambulatory basis.
