Background : Theoretically as the waiting-time of patient is estimated in queueing, many men and much money are needed. But being the estimation of patient s waiting-time very important in hospital service, so the continuous monitoring of waiting-time is inevitable. To verify that the estimation of waiting-time using parking time is economical, effective and continuous monitoring method and to develop utilizing the method, this study was done. Method : In parking confirmation office, the personnel of parking office wrote parking confirm time, chart number and whether medical examination and treatment finish or not in parking ticket. The next day the parking tickets were gathered and the above data were input. The input parking data were connected with the hospital outpatient file indexing chart number. Then the patient' s data for department, new patient or not, reservation or not, receipt time and payment time were retrieved. The group for finishing medical treatment were compared with that for not finishing in average time lag between confirmation and out-time for hospital. And In-time for hospital, receipt time, payment and out-time for hospital were also analyzed. Result : Confirming parking ticket, the group for finished medical treatment left hospital after 7 minutes. This result showed that the patient for finished medical treatment left hospital immediately. So parking time was reasonable to estimation of hospital-time was concluded. The time for medical treatment, diagnosis and test was constant for all patients and short for waiting time, Then I concluded that the parking time was reasonable for estimation patient's waiting time. Overall patient's waiting time was 113 minutes and new patient's time was 149 minutes, old patient's times was 109 minutes. Waiting time for reservation patient was 98 minutes and for non reservation patient was 122 minutes. The time from hospital arrival to payment was 50 minutes for the group of reservation patient and 69 minutes for non-reservation group. The time from payment to hospital leaving was 51 minutes and 56 minutes for non reservation group. The short time difference between reserved group and not reserved group from payment to hospital leaving time was due to bottle neck effect. Conclusion : The estimation of patient's waiting time using parking time was reasonable because the possession of car was common and the time for medical treatment was equal and the patient after treatment left hospital immediately. Using this method, timely, fast evaluation and continuous monitoring of the intervention effect were possible.

ATMega8535 Controller is the ideal solution for use as a standard controller in many applications. The small compact size combined with easy program updates and modifications, make it ideal for use in machinery and control systems, such as alarms, card readers, real-time monitoring applications and much more. This board is ideal as the brains of your robot or at the center of your home-monitoring system. Today, most drivers must use a parking place day by day. Therefore we make time shorten. Using above-mentioned ATmega8535, a sensor of infrared rays, led and lcd, we will make a parking system which is able to display parking situation and lead a car at the best position of Parking easily and quickly. Trying this project, we will be more closer to practical application of electronic engineering bit by bit.

본 연구는 주거지역에 대해 주차환경의 정량적 평가지표를 개발하는데 목적이 있다. 주차장법에 의한 주차환경개선지구 선정시 주차장확보율만이 평가지표로 활용되고 있다. 자치단체별로 주차환경개선 사업이 활발히 추진되고 있지만, 주차환경을 평가할 수 있는 분석지표가 없어 사업의 우선순위를 매기기 어렵고, 사업시행 이후 효과분석을 위한 모니터링이 어려운 실정이다. 이에 본 연구에서는 주거지역에 대한 주차환경 수준을 평가할 수 있는 가능한 지표를 검토한 후 전문가 집단에 의한 AHP 분석을 통해 실질적으로 자료수집이 용이한 평가지표(주차장확보율, 이용률, 불법주차율, 수요변화율)를 도출하고, 평가지표에 대한 가중치를 산출하였다. 이를 근거로 주차환경 평가도를 마련하였으며, 현장에서 수집된 주차실태조사 자료를 분석에 활용하였다. 본 연구의 평가도가 주차환경 개선사업 수행시 사업의 우선순위 선정 및 모니터링에 활용될 수 있을 것으로 기대된다.

주차장에서 빈 공간을 분석하는 기술은 주차공간의 효율적인 사용이나 교통이 혼잡한 곳에서 유용하게 사용될 수 있다. 그러나 기존의 주차 공간 분석 방법은 실용적이지 못하거나 빠른 처리속도가 필요하다. 그래서 본 논문에서는 실시간 주차검출에 적합한 주차 모니터링 방법을 제안하고자 한다. 제안된 방법은 그레이레벨 영상을 이용하여 주차여부를 확인하고, 주차공간을 분석하는 방법을 사용하였다. 제안된 방법의 성능을 확인하기 위해 야외 주차장에서 129개의 동영상을 획득하여 실험한 결과 98.5%의 주차 공간 분석에 성공하여 제안된 방법이 주차 공간 분석에 효율적인 것을 입증하였다.

RFID 기술은 도서관과 보안 분야와 같은 제어와 관련한 분야에서 유용하게 이용되고 있다. 차량의 통제는 이러한 분야 중의 하나로서 많은 장점이 있다. 특히, 승용차, 트럭 등에 태크(Tag)를 사용할 수 있다. 차량이 제한된 장소나 혹은 주차 구역에 진입할 때 리더기가 태그를 평가 한다. RFID 리더는 진입하는 차량을 인증하면서 차량 진입 시간을 서버에 전송한다. 그러면 장치가 활성화 된다. 차량이 주차구역에서 이동하면 RFID 리더기는 차량이 출발한 시간을 기록한다. 본 논문에서 우리는 불법 주차 모니터링 방법을 제안한다. 특히, 차량 소유자가 불법으로 차량을 주차할 경우 빠르고 정확하게 이와 같은 정보를 기록하는 방법을 제안했다.

In our contribution, the new idea of parking/moving discrimination is proposed by using Three Line Scanner Imagery. The framework of our study consists of three main stages: preprocessing, vehicle detection and parking/moving detection respectively. First two stages of framework have been done in our previous work. Parking/ Moving Discrimination algorithm have been developed by using generic vehicle characteristics and some principle of photogrammetry. By using detected vehicles from our previous work, stopping/moving vehicles are able to discriminate. Moving vehicle is detected by detecting generic moving vehicle in TLS, inter-band gap. Stopping vehicle is verified by 3 dimensional viewing of Stereoscopic measurement. Finally, the conceptual framework has been done and the result will been realized soon.
