개량 Mulching 재배법에 의한 조기재배담배밭부근 뽕잎이 춘잠작에 미치는 영향을 알고져, 담배 밭으로부터 뽕밭이 서북쪽에 위치하고, 경사도는 20% 미만으로 뽕밭이 높게 위치하였으며, 시험기간중의 풍향은 담배밭을 거쳐 뽕밭 쪽으로 불어오는 남풍과 동남풍이 각각 36%로 주풍이었고 동풍이 그 다음으로 18%의 상태인, 담배 밭으로부터 l00m 떨어진 처리구를 대조로 하고 10m, 25m, 50m, 80m별로 시험구를 설정하여 각처리의 뽕으로 누에 사육을 통한 영향여부를 조사한 결과, 시험사육기간중 육만으로 식별할 수 있을 정도의 중독잠 내지 폐사잠은 발견할 수 없었으나 그 결과에 나타난 피해상황은 다음과 같다. 다만, 같은 뽕밭의 뽕이라도 경사도가 낮고, 담배 밭에 가까운 곳일수록 뽕나무의 발육이 양호하였고, 엽질면에서도 우량한 뽕잎의 사육결과였음에도 불구하고, 본 시험결과에 대한 분석결과를 요약하면 다음과 같다. 1. 5영극도 잠종중에는 담배 밭으로부터 25m 구까지 감초의 영향을 미쳤다. 2. 생견 1ι과수 역시 담배 밭으로부터 25m 구까지는 고치가 작았다. 3. 전견종과 견층종에서도 담배 밭으로부터 25m 구까지 피해를 주었으며 그 정도는 전견중보다 견층중에 더 큰 영향이 미치어서 그 결과 견층비율이 일층 낮아지는 경향을 보였다. 4. 옥견포함 1만두 수견량에서도 담배 밭에서 25m 구까지는 수량이 감소되고 있으며 그 정도는 1차 시험에 있어서는 처리구는 대조에 비하여 10m 구에서는 2.4kg, 25m 구는 2.5kg의 차이로 대조보다 19%가 감수되었으며, 2차에서는 10m 구는 1.8kg, 25m 구는 1.5kg의 차이로 각각 11%, 9%의 감수를 보였다. 이상을 종합하여 보면 대조구의 뽕의 질이 좋지 못하였던 점을 감안한다면 본 시험에서 얻어진 거리 및 감량이상의 피해를 받을 가능성을 시사하며, 본 시험에서의 피해한계 거리는 25m∼50m 사이에 있는 것 같다. The studies are to know how much cocoon crops is damaged by the stained leaf with nicotine produced from the tobacco field cultivated in mulching system in spring season and by residual nicotine in autumn season. Furthermore, the new knowledges are to make both industries keep up with their development. In spring season mulberry field is located higher on the West-North of tobacco held below 20 degrees of slope and with 36 per cent of East-South wind and 18 per cent of South wind blowing from tobacco field to the mulberry field. In addition, silkworm larvae are fed with the mulberry leaf produced in the different plots placing by the different distances, 10m, 25m, 50m, 80m, and 100m far from the tobacco field as a control and it is also considered that narcotic larvae including the dead larvae are not observed. On the other hand, it is noted that better leaf quality and abundant growth of mulberry tree is produced from the mulberry fold closer to the tobacco field and with a low slope. 1) Maximum weight of larval body at the 5th stage is damaged by the stained leaf with the nicotine up to 25m far from the tobacco field. 2) The larvae fed with the mulberry leaf in mulberry Held up to 25m far from the tobacco field produce small number of the fresh cocoons per 1 litre. 3) Low single cocoon weight and low cocoon shell weight are produced by the poison damaged larvae fed with the mulberry, leaf up to 25m far from the tobacco field and weight of cocoon shell is damaged higher than the single cocoon weight. It is resulted in low percentage of cocoon shell. 4) Cocoon yield including the double cocoon from 10,000 larvae is decreased by the larvae fed with the stained leaf in the mulberry fold up to 25m far from the tobacco field and 19 per cent of cocoon yield is decreased with 2.4kg of cocoon yield in 10m plot and with 2.5kg of cocoon yield in 25m plot at the first season and at the 2nd season with 1.8kg of cocoon yield in 10m plot and with 11.5kg of cocoon yield in 25m plot, 11 per cent and 9 per cent of cocoon yield including double cocoon from 10,000 larvae is decreased, as compared with the control, respectively. With these results, it is observed that nicotine damage is occurred to the silkworm larvae if the larvae are fed with the leaf in the mulberry Held within 25m-50m far from the tobacco field.

본 논문에서는 다양한 종류의 CNC 선반을 위한 공작물 적재 장치의 제어장치를 설계하였다. CNC 선반은 자동차 부품, 항공기 부품, 선박 부품 등 각종 부품을 가공하는데 사용되는 기계장치이다. CNC 선반의 대부분은 척에 가공전의 원자재를 넣어주면 자동으로 최종 부품까지 가공한다. 가공 전 원자재와 가공 후 공작물을 CNC 선반에 장착하고 탈착하는 것은 작업자가 수행하는 경우도 있고, 겐츄리 로봇, 산업용 로봇, 스카라 로봇 등이 수행하는 경우도 있다. 로봇들이 수행하는 경우에는 가공 전의 원자재를 적재하는 자동 적재 장치와 가공 후의 공작물을 적재하는 자동 적재 장치가 필요하다. 또한 고속화, 고능률화, 복합화, 다기능화, 시스템화를 추구하면서 이에 대응할 수 있는 주변장치의 요구가 많아지고 있고, 이를 위해 기존의 시스템과는 달리 원자재와 가공품의 크기에 맞춰 조절이 가능한 자동 적재 장치가 필요하다. CNC 선반을 위한 적재 장치의 제어장치는 TMS320F28377D 를 주연산장치로 사용하였고, 공작물 및 원자재 위치 감지 센서, 공작물 및 원자재가 올라가는 Table 의 위치를 감지하는 위치 감지 센서, 원판과 Lifter 의 결합을 감지하는 고정핀 감지 센서, 원판의 높이를 감지하는 Lifter 센서, 레버 및 스위치의 입력을 받기 위한 입력부와 Lifter 모터, Table 모터, 고정핀, 에어 컴프레셔의 제어를 위한 출력부, 5 축 로봇 제어장치와 통신을 위한 CAN 통신부로 구성하였다. 적재 장치의 제어장치를 설계 및 제작하였고, 제어를 위한 알고리즘을 개발하여 프로그램을 작성하였다.

To understand the current status of neonatal surgery in Korea, a survey was made among the 36 members of the Korean Association of Pediatric Surgeons. The response rate was 75 % (26 surgeons in 20 hospitals). Five hundred fifty three neonatal surgical patients treated in 1999 were analyzed. Regional numbers of patients were closely related to the regional population in most areas. Ano-rectal malformations (17 %), pyloric stenosis (16 %), Hirschsprung's disease (13 %), atresia/stenosis of the gut (11 %), esophageal atresia (8 %) were the most common anomalies treated. The majority of operations were done within the first week of life. Seventy one per cent of cases were major life threatening or so-called neonatal index cases. Over-all mortality was 8 per cent. Higher mortality was observed in patients with diaphragmatic hernia (26 %), gastro-intestinal perforation (18 %), NEC (18 %), and esophageal atresia(14 %). Higher mortality was observed in patients with extremely low birth weight (33%) and low birth weight (18 %). Associated anomalies were observed in 20 %. Prenatal ultrasound was performed in 36 per cent with sensitivity of 20 %. Result of this study was compared to the previous report (1994) and that of Japan (1998).

Purpose: Thyroid cancer is rare in childhood. Although thyroid cancer is biologically more aggressive in children because of the high incidence of lymph node metastasis and distant metastasis when compared with that of adults, the prognosis is better. This study investigated the prognosis of pediatric differentiated thyroid cancer with 15 years or greater follow-up and we consider the proper treatment of pediatric differentiated thyroid cancer. Methods: From January, 1979 to December, 1994 during 16 years, 17 patients younger than 17 years old and who underwent thyroid surgery for well differentiated thyroid cancer at the Department of Surgery at Presbyterian Medical Center were retrospectively reviewed by the medical records and they were interviewed by telephone. Results: Total thyroidectomy was performed in 4 patients (23.5%), subtotal thyroidectomy was performed in 10 patients (58.8%) and lobectomy was performed in 3 patients (17.7%). The mean follow-up period was 23.5 years (range: 15∼28.2 years) and recurrence was found in 7 cases (41.3%). Five cases (29.5%) showed locoregional recurrence and 2 cases (11.8%) showed distant metastasis. Postoperative radioiodine (<SUP>131</SUP>I) therapy was done in 6 cases (35%) and 6 cases (35%) underwent radioiodine therapy as a therapeutic modality for metastasis. Conclusion: The pediatric well differentiated thyroid cancer in this study showed high rates of lymph node metastasis at the time of diagnosis and a high recurrence rate, but the prognosis was good (100% overall survival rate during the follow-up period). Therefore, total thyroidectomy, radical lymph node dissection and postoperative radioiodine therapy are considered the initial patient management. This aggressive therapeutic management can decrease of the recurrence rate and increase the therapeutic effect. A radioiodine scan and thyroglobulin can used for follow-up.

The prevalence of microprocessor-based controllers in automotive systems has greatly increased the need for tools which can be used to validate and test control systems over their full time range of operation. The objective of this paper is to develope the real time simulator of anti-lock braking system using hardware-in-the-loop simulationbased on a personal computer. By use of this simulator, the analyses of commercial electronic control unit as well as the validation of the developed control logics for ABS were performed successfully. The simulator of this research can be applied to development of more advanced control system, such as traction control cystem,vehicle dynamic control system and etc.<br/>
