대규모 연초건조장 부근의 뽕잎이 잠작에 미치는 영향을 알고자 무독상엽으로 인정되는 잠업시험장 (수원)의 유업을 대조로 하여 충남 논산군 논산읍 소재 연초건조장으로부터 30∼50m, 300∼400m 및 700∼800m 지점에 위치한 유전의 뽕을 채취하여 이를 소잠시부터 상족전까지 급여 시험한 결과를 분석하여 각각의 계량형질에 미친 영향을 요약하면 다음과 같다. 1. 누에 경과는 1령부터 3령까지는 대조와 같았으나 4령기부터 길어지기 시작하여 5령 및 전령에서 유의차가 있었다. 2. 숙잠발현기간은 대조구에 비하여 누에의 경과 및 발육이 고르지 못하여 건조장에 가까운 순으로 길었다. 3. 감잠비율은 장잠, 족중, 명중 공히 건조장에 가까운 처리구가 가장 높았고 특히 장잠 및 난중에서 심했다. 4. 화용비율은 근거리구가 가장 낮았고 중간 및 원거리구는 같은 수준으로 대조와 유의차가 없었다. 5. 전견중, 견증중은 각 처리구 공히 피해가 인정되었으며 대조구와 유의차가 있었고 견층비율은 대조에 비하여 각 구가 공히 같은 비율로 감소되어 유의차가 없었다. 6. 각견비율은 대조구의 상견비율 87.1%에 비하여 각 처리구간에 유의차가 있었으며 근거리구가 가장 고치가 고르지 못하고 중간거리구와 원거리구는 같은 수준이었다. 7. 수견량 (대 4령기잠 1만두 상견)에서는 연초건조장에서 가까운구가 대조구에 비하여 현저히 감수되었으며 중간 및 원거리구는 같은 수준으로 감수되어 고도의 유의차가 있었다. 이상을 종합하여 보면 충질, 견질 및 수견량에 피해를 주는 거리는 건조장과 유전의 위치 및 풍향 등에 따라 다르겠으나 본 시험에서는 800m까지도 피해가 있었다. 8. 본 시험은 Nicotine에 오염된 뽕을 채취하여 잠업시험장에서 누에를 사육한 관계로 누에가 오염된 뽕을 식하하므로 생기는 식중독만을 인정할 수 있다. 따라서 현지에서 누에를 사육할 경우에는 뽕 오염에 의한 식중독뿐만 아니라 연초건조장 부근의 오염된 공기가 누에의 피부에 접촉되어 발생하는 경피독 및 누에의 호흡시 기문을 통하여 일어나는 호흡 독에 의한 피해도 예상할 수가 있는 것이다. The objective of the present study was to investigate the effect of nicotine-contaminated mulberry-leaf, which was grown in the vicinity of tobacco drying plant (TDP), on cocoon crop. Mulberry-leaf harvested from the field at Sericultural Experiment Station (SES), Suweon, Korea, was used as control, supposedly nicotine-free leaf. Leaf harvested from the field in the distances of 30-50m, 300-400m and 700-800m from TDP was fed during the whole larval stage of the silkworm at SES. The effect of leaf in each treatment level on the quantitative characters of the silkworm was summarized as follows; 1. Larval duration from 4th instar on was significantly longer in the TDP-leaf treatments than for the control. 2. Duration of matured silkworm appearance became longer as the distance of the mulberry-field from TDP got shorter, because the larval duration and growth of the silkworm were not uniform in the TDP-leaf treatments. 3. Mortality rates during the late larval, cocoon spinning, and pupal stages were highest for the 30-50m leaf, especially mortality rates during the late larval and pupal stage were serious. 4. Pupation rate was lowest for the 30-50m leaf and those for the 300-400m and the 700-800m leaf were not significantly different from that of the control. 5. Nicotine damage to cocoon weight and cocoon shell weight was significant in each TDP-leaf level. Cocoon shell ratio was reduced at the same extent in each level, compared with the control. 6. The ratio among cocoon-classes was significantly different between treatments, compared with best-cocoon ratio of 87.1% for the control. Cocoons were not uniform for the 30-50m leaf, and those for the 300-400m and the 700-800m leaf were as almost uniform as those for the control. 7. Loss of fresh cocoon yield became greater as the distance of the mulberry-field from the TDP-got shorter. In conclusion, the critical distance of mulberry-field, which influences larval health, cocoon quality and yield, appeared to be 800m from the TDP. Such other factors as wind direction and topographic location may be involved in the critical distance. 8. From the present experiment, we could obtain only the effect of nicotine on the silkworm through digestive system, since the silkworm was raised at SES in Suweon. If the silkworm, were raised in the vicinity of the TDP, poison effect of nicotine on the silkworm could beo expected through exoskeleton and tracheal system as well as through digestive system.

Craniofacial reconstructive procedures are frequently peformed with rigid fixation of the bone. During the period of active bone growth such manipulation may influence bone development. The purpose of this study was to determine the effects of metal plating of the mandible on the growth and morphology of the mandibulofacial skeleton. New Zealand white rabbits, 6 to7 weeks of age, were divided into 5 groups. They were designated as group Ⅰ(nonoperated control, n=10), group Ⅱ (rigid fixation of mandibular body after vertical osteotomy, n=10), group Ⅲ(rigid fixation without osteotomy, n=10), group Ⅳ(interosseous wire fixation after osteotomy, n=10), and group Ⅴ(rigid fixation and removal of plates and screws 4 weeks after osteotomy, n=7). Rabbits were sacrificed 12 weeks after operation and dry skull preparations were grossly measured and analyzed by direct measurement and by dorsoventral skull x-rays. Measurements taken were length, thickness, angle, and area of the mandibulofacial skeleton. Three-dimensional CT was used for volumetric measurement of the mandible. The data wee compared between the operated and nonoperated sides and significant differences between groups were evaluated using the paired t-test, the ANOVA test, and Dunn's test. The following results were obtained: 1. The length of the whole mandible and the anterior mandibular segment was decreased in groups ⅡandⅢ, compared with group Ⅰ(p<0.05). These results show growth restriction of the plated mandible regardless of osteotomy. 2. The maxillary alveolus of the operated side was more anteriorly placed in groups Ⅱ and Ⅲ, compared with group Ⅰ (p<0.05). 3. The thickness of the operated mandibular body showed a significant increase in groups Ⅱ and Ⅲ, compared with group Ⅰ(p<0.05). 4. The length of the zygomatic arch of the operated side in all the experimental groups showed a significant decrease, compared with group Ⅰ(p<0.05). The angular divergence of the mandibular ramus from the sagittal midline of the skull was increased in the operated side of groups Ⅱand Ⅲ, compared with the nonoperated side (p<0.05). 5. Volume measurements of the mandible in groups ⅡandⅢ showed a significant reduction of the volume on the operated sides in the anterior mandibular segment, compared with group Ⅰ(p0.05). The volume of the operated mandibular body showed a significant increase in groups Ⅱ and Ⅲ, compared with group Ⅰ(p<0.05). All gruops showed no significant difference in total hemiman dibular volume of the operated side compared with the nonoperated side. These results show that rigid fixation of mandibular fractures during the growth period causes a more severe growth restriction than either osteotomy or interosseous wiring.

목적: 현 병원의 CT 예약시스템은 2000년 중반에 도입이 되었다. 그 시스템 안에서 내⋅외부고객 만족을 위한 QI활동, CS활동 및 시스템 개선 활동을 하고 있었으나, 현 급변하고 있는 의료 환경과 환자들의 의식수준, 증가되고 있는 환자를 현 예약 시스템이 따라가지 못하는 실정이다. 이에 본 논문에서는 새로운 예약 알고리즘을 개발하고 적용시켜, 더욱 정확하고 안전한 검사를 도모하고, 내⋅외부고객 만족도를 상승시키고자 한다. 대상 및 방법: 예약시간은 각 진료부서와 통합예약센터에서 30분 단위로 설정 되어 있고, 당일요청검사는 시간당 2건으로 설정되어 있으며, 당일검사는 진료부서 및 예약센터에서 유⋅무선 통화와 당일검사예약프로그램을 사용하고 있다. 시간별로 가능한 검사는 병원 시스템 및 검사 프로토콜에 따라 예약시간이 다르다. 이미 시행되었던 예약스케줄을(Oracle 데이터베이스) PERT CPM 기법으로 Big data를 분석하여, Visual studio 2017(Visual Basic)을 이용해 프로그램을 개발하고자 한다. 결과: 예약 프로그램 도입 시, 고객이 진료 후 최소 2시간 이내 검사가 가능하고, 당일 실시간 예약이 가능함에 따라, 예약 부도를 보완하는 시스템을 활용하여 효율적인 예약 스케줄을 관리한다. 이를 토대로 시뮬레이션 한 결과, 예약이 10~20% 증가한 것으로 나타났다. 그리고 개선된 검사시간 관리로 예약관리가 더욱 원활하고, CT 장비 특성별로 검사가 용이한 장비를 우선순위로 하여, 예약이 가능한 시스템이 구축될 것이다. 결론: 진료부서와 CT실 사이 소통 간소화, 부서 간 업무 만족도 증가, 고객과 의료진 간 실시간 피드백으로 내⋅외부고객 만족도 상승이 있을 것으로 사료 된다. Purpose: The current appointment system for taking computed tomography (CT) was introduced in mid-2000 and various actions for the system improvement have been made to satisfy both hospital employees and patients. However, the current appointment system cannot keep up with the rapid change of medical environment, the enhanced consciousness level of patients, and the growing number of patients. Hereupon, a new algorism which will increase satisfaction of both hospital employees and patients was developed for more accurate and more safe medical examinations. Material and methods: The established appointments at each department and appointment center are set to be every 30 minutes starting from 9:00 AM. In addition, appointments for the same day examination appointment can be made up to two appointments through phone calls or the on-line by same day examination appointment program from each department and appointment center. The examination time differs depending on the hospital system and inspection protocol. I want to develop a new program with the PERT CPM method based on the analysis using Visual Studio 2017. Result: Patients can be examined within at least 2 hours after each treatment and an efficient management of appointment schedule will be achieved by decreased disruption in the schedule caused by canceling appointments. As a result, the appointment rate will be increased by 20~30% and the system that allows priority for the examinations backed up by the examination equipment. Conclusion: The communication between the treatment department and the CT department will be simplified, the job satisfaction at both departments will be improved, and the satisfaction of patients and hospital employees will be improved by the real time feedback.
