본 논문에서는 인체 감지형 자기장 코일의 감지거리 13.4mm를 이용한 디지털 잠금장치 설계에 관한 연구를 하고자 한다. 현재 사용되는 디지털 잠금장치와는 다르게 실외 케이스는 기존의 고유번호 입력버튼, 조명, 보호 커버, 해당 pcb, 외곽 케이스, 데이터 전송 케이블 등이 삭제되고 구동전원 ON/OFF 스위치와 비상 단자로만 구성하였다. 실내 케이스는 내부에 설치 된 자기장 코일기판이 유리문 몸체에 밀착된 상태로 12mm 간격의 맞은편 실외에서 전송되는 전기적 저항 값을 감지하 면 그에 대응하는 유도전류가 흐르게 된다. 이때, 해당 원형 코일의 주파수 변환이 이루어지면 자기장 코일은 센서의 역할을 수행하게 된다. 센서로서의 자기장 코일은 인체가 감지되기 전과 감지 후에 출력되는 발진 주파수의 크기 변화를 감지하고 2,000%이상 증폭시켜 디지털 신호로 변환 조합한 다음 전용 소프트웨어에 전송하여 내장된 고정 데이터와 비교하여 검색하 는 역할을 한다. 연구결과 자기장 코일 12.8Ø 기준으로 인체의 터치 면적에 따른 감지시간은 30% 대비 0.08sec, 80% 대비 0.03sec이며 감지거리는 13.4mm로 최고 수준으로 측정되었다. This study evaluated a digital locking device design using detection distance of 13.4mm of a human body sensing type magnetic field coil. In contrast to digital locking devices that are used nowadays, the existing serial number entering buttons, lighting, number cover, corresponding pcb, exterior case, and data delivery cables have been deleted and are only composed of control ON/OFF power switches and emergency terminals. When the magnetic field coil substrates installed inside the inner case detects the electric resistance delivered from the opposite side of the 12mm interval exterior contacting the glass body part, the corresponding induced current flows. At this time, the magnetic field coil takes the role as a sensor when coil frequency of the circular coil is transformed. The magnetic coil as a sensor detects a change in the oscillation frequency output before and after the body is detected. This is then amplified to larger than 2,000%, transformed into digital signals, and delivered to exclusive software to compare and search for embedded data. The detection time followed by the touch area of the body standard to a 12.8Ø magnetic field coil was 30% contrast at 0.08sec and 80% contrast at 0.03sec, in which the detection distance was 13.4mm, showing the best level

Primary multiple cancer means that more than two cancers occur independently in an individual. There have been many reports on primary multiple cancer since Billorth reported it for the first time in 1889. Owing to advancement of diagnostic procedures, reported cases of primary multiple cancers have been increased in number. The most frequent association in stomach cancer was followed by esophagus, larynx, liver, uterus. Here we report 1 case of primary multiple cancer who was a 60-year-old woman with epigastric pain. Endoscopy disclosed white patch and irregular base lesion on the antrum. A CT scan of the abdomen showed a lobulated soft tissue mass in the left kidney. The biopsy specimens showed adenocarcinoma on stomach and renal cell carcinoma on kidney. (Korean J Gastroenterol 1995;27:734 - 738)

Inflammatory fibroid polyps(IFP) is a relatively rare, benign polyp which is composed of fi- brous connective tissue, blood vessels, and infiltration of eosinophils. The majority of inflam- matory fibroid polyps has been reported with pathologic specimen in stomach and small intes tine. Terminal ileal inflammatory fibroid polyps differ from gastric lesion because they are larger and are almost all pedunculated. As a result, they tend to produce intussusception with intestinal obstruction. We present a case of inflamrnatory fibroid polyp of distal ileum causing intussusception with literature review.(Korean J Gastroenterol 1994; 26: 874 878)

This study was done to examine whether cigarette smoking improved smooth pursuit eye movement(SPEM) abnormalities in chronic schizophrenic inpatients. Fifteen schizophrenic and twelve alcoholic subjects abstained from their usual cigarette smoking for a minimum of nine hours and their baseline performances during the constant velocity smooth pursuit tasks were assessed. Then, the subjects smoked as much as they desired in a 10 minutes period and were retested immediately after smoking and 15 minutes after smoking. Electrooculographic recordings during the eye movements were converted and saved as digitized files. Power spectral density curves and natural logarithm value of signal/noise(Ln S/N) ratios were computed from them. In the schizophrenic patients, Ln S/N ratios increased significantly immediately after smoking compared to baseline. But, Ln S/N ratios showed no statistically significant changes after 15 minutes compared to baseline. In alcoholic subjects, Ln S/N ratios showed no statistically significant changes immediately after smoking and after 15 minutes compared to baseline. In conclusion, SPEM was improved in schizophrenic patients immediately after smoking and we hypothesized that nicotinic receptor dysfunction maybe a candidate mechanism for smooth pursuit eye movement abnormalities in schizophrenia.

본 논문에서는 효율적인 환자관리를 위한 링거액 감지기 및 송수신기를 설계 하고자 한다. 링거액 감지기 및 송수신기는 메인 제어부, 링거액 감지부, 디스플레이 및 경고 발생부, 무선 송수신부, 전원 공급부로 구성된다. 메인 제어부에서는 GC89L591A0-MQ44IP의 CPU를 사용하여 전체 시스템을 제어하고 링거액 감지부는 수광부에 TSL235R-LF 포토다이오드, 투광부에 Water-Clear Type LED를 적용하였다. 또한, 디스플레이 및 경고 발생부는 7-세그먼트와 적색 LED를 적용하였으며 무선 송수신부는 NR-FPCX 모듈을 사용하여 데이터를 송수신하였다. 전원 공급부는 건전지를 사용하며 일반 전원이나 충전식 전원도 사용할 수 있도록 하였다. 따라서, 효율적인 환자관리를 위한 링거액 감지기 및 송수신기 설계에 대한 연구 결과 링거액이 포토다이오드에 의해 감지되었을 때 주파수는 11.95kHz이며, 감지되지 않았을 때는 9.6kHz로 측정되었다. 이때, 링거액의 감지 데이터가 링거액 송신기를 통해 출력되지 않을 때는 “0” 으로, 출력되었을 때는 해당 병실의 호실 정보가 링거액 수신기에 표시됨을 확인 할 수 있었다. 또한, 링거액 감지기의 사용전원은 신호가 감지되지 않을 때에는 Sleep 모드로 전환하여 배터리 절약 모드로 동작하며 링거액 송수신기는 대략 700m이내의 거리에서 무선 송수신이 가능하다. This paper reports a Ringer"s solution detector and transceiver design for the efficient management of patients. The ringer"s solution detection and transceiver consisted of the main control part, ringer"s solution detection part, display and warning light part, wireless transceiver, and power supply part. The light receiving part of the ringer"s solution detection part employed TSL260R-LF photodiode; light permeating part, Water-Clear type LED; and wireless transceiver part, the RF wireless data transceiver module, NR-FPCX. As a result of this Ringer"s solution detector and transceiver design that can manage the patient efficiently, it was found that when the ringer"s solution was detected by the double photodiode, the operating frequency was 11.95kHz; when it was not detected, the number was 9.6kHz. In the ringer"s solution receiver, when the ringer"s solution was detected, the number was 0. The corresponding unique RF code was displayed when not detected. The power used in the ringer"s solution detection part was converted to the Sleep mode to operate under battery save mode. The ringer"s solution transceiver can exchange wireless communication approximately within a 700m radius.

This thesis is about the system where the solar module is attached to the high functional guardrail posts with anti-weed, anti-plant, and road-kill applied to produce internal power, enabling the integrated control and real-time monitoring of appearance of wildlife and road conditions using the USN. The whole system consists of a photovoltaic module(PV), a detection sensor(pyroelectric), a controller(operation select and motion sensor), the USN system, the DB(sound and flash), an output unit of sound and flash, and the control system of road-kill prevention and safety induction for vehicles. Thus this study aims to address the remote control and monitoring system of multipurpose guardrails to improve road environment, prevent road-kills, protect wild animals, and guide cars safely by using the USN which is combined with new renewable energy and IT convergence technology. As a result of the study on the remote control and monitoring system using the USN, it was ascertained that the response time of the unmanned sensing system was within 5.1 ms with the current consumption of 0.328 mA, and the data transmission speed of the remote control system was 250 kbps with the current consumption of 0.283 mA.

Objectives : We investigated the association of Val108/158Met polymorphism on catechol-O-methyl transferase(COMT) gene with smooth pursuit eye movement(SPEM) abnormality in Korean schizophrenia patients. Methods : We measured SPEM in 217 Korean schizophrenia patients(male 116, female 101) and divided them into two groups, one was a good SPEM function group and the other was a poor SPEM function group. Then we analyzed Val108/158Met polymorphism on COMT gene. We compared the differences of genotype and allele distributions of the polymorphism on COMT gene between the two groups. Results : The natural logarithm value of signal/noise ratio(Ln S/N ratio) of the good SPEM function group was $4.39{\pm}0.33$(mean${\pm}$s.d.) and that of poor SPEM function group was $3.17{\pm}0.71$. There were no statistically significant differences of age and male/female ratio between the two groups. There were no significant differences of genotype or allele distributions of the Val108/158Met polymorphism on COMT gene between the two schizophrenic groups. Conclusions : The results suggest that Val108/158Met polymorphism on COMT gene is not related to SPEM function abnormality in schizophrenia.
