대한복강경위장관연구회가 2004년 전국에서 시행된 복강경 위 수술의 현황을 조사하였다. 모두 36개의 기관으로부터 38명의 외과의가 설문에 응답하였다. 2004년 한 해 동안 시행된 복강경 위 수술은 총 1,089예였고 1995년부터 2004년까지 시행된 복강경 위 수술을 누적하면 모두 2,386예였다. 2004년에 위선암 환자에서 시행된 복강경 위 수술은 2003년보다 약 2배 많은 754예였다. 위선암에 대한 근치적 위절제술인 복강경보조위아전절제술 및 복강경보조위전절제술은 2001년도를 전환점으로 급속히 증가하였다(2001년 55예, 2002년 150예, 2003년 364예, 2004년 738예). 특히 복강경보조위전절제술은 작년에 폭발적 인 증가를 보였다. (2003년 20예, 2004년 112예). 그러나 복강경보조유문부보존위절제술 및 복강경보조근위부위절제술과 같은 복강경보조기능보존위절제술은 작년 각각 1예씩 시행되어 아직 보편화되지 않았다. 위 점막하종양에 시행된 복강경위쐐기절제술은 142예였다. Hand-assisted laparoscopic surgery는 2001년 39예, 2002년 55예, 2003년 49예가 시행되었으나 2004년에는 단 5예만 시행되어 급격한 감소를 보였다. 고도비만수술은 2003년도에 시작되어 2004년에는 49예로 증가하였다. 위선 암에서 복강경위수술의 적응증에 대한 견해로서 19명이 조기위암에서 시행한다고 하였고 7명은 적응증을 T2N0까지 넓히고 있었다. 앞으로 보험문제가 해결이 되고 장기 성적이 나온다면 위선암에 대한 복강경 위 수술은 널리 보편화될 것이다. The Korean laparoscopic Gastrointestinal Surgery Study Group made a survey of laparoscopic gastric surgeries which were performed in Korea during 2004. Thirty-eight surgeons from 36 Institutions responded to the questionnaires. One thousand eighty-nine laparoscopic gastric operations were performed during 2004. The cumulative number from 1995 to 2004 was about 2,386. Seven hundred fifty-four operations for a gastric adenocarcinoma were performed during 2004 which is almost two times the number performed during 2003. Laparoscopic radical procedures, such as a laparoscopy-assisted distal gastrectomy or total gastrectomy (LADG and LATG) have increased rapidly since 2001 (55 cases in 2001, 150 cases in 2002, 364 cases in 2003 and 738 cases in 2004). Especially, laparoscopic total gastrectomies were explosively adopted last year (20 cases in 2003 and 112 cases in 2004). However, laparoscopic function-preserving gastrectomies, which included one laparoscopy-assisted pylorus-preserving gastrectomy and laparoscopy-assisted proximal gastrectomy, are rarely performed at this time. One hundred forty-two wedge resections for a gastric submucosal tumor were performed during 2004. Hand-assisted laparoscopic surgery (HALS) was performed in 39 cases in 2001, 55 in 2002, and 49 in 2003; however, only 5 such surgeries were performed during 2004. In 2003, laparoscopic bariatric surgery began, and during 2004, 49 operations were performed. In terms of indications of laparoscopic gastric surgery for adenocarcinoma, 19 surgeons performed a LADG only for a T1 lesion, and 7 surgeons extended their indications to T2N0 lesions. In the near future, laparoscopic procedures for gastric cancer will be widely adopted in Korea if the medical-insurance obstacle is overcome, and the long-term survival results are verified.

본 연구는 비육돈 사료내 Se과 비타민 E를 첨가하였을 때 육질 특성 및 저장성을 알아보기 위해 실시하였다. 3원 교잡종($Landrace{\times}Yorkshire{\times}Duroc$) 비육돈 80두를 공시하였으며, 시험개시시의 체중은 74.74 kg이었다. 시험설계는 Se의 첨가수준과 첨가형태에 따라 1) CON(basal diet), 2) ISE2 (basal diet + 0.2 ppm inorganic Se + 100 ppm vitamin E), 3) ISE4(basal diet + 0.4 ppm inorganic Se + 100 ppm vitamin E), 4) OSE2(basal diet + 0.2 ppm organic Se + 100 ppm vitamin E) 및 5) OSE4(basal diet +0.4 ppm organic Se + 100 ppm vitamin E)로 5처리를 하여 처리당 4반복, 반복당 4마리 씩 완전임의 배치하였다. 가열 감량은 ISE4 처리구가 CON 처리구와 비교하여 유의적으로 낮게 나타났다(p<0.05). 조지방 함량은 OSE2 처리구가 다른 처리구들과 비교하여 유의적으로 높게 나타났다(p<0.05). 적색도를 나타내는 $a^*$-값은 저장 10일째 OSE2 처리구가 다른 처리구들과 비교하여 유의적으로 높게 나타났다(p<0.05). TBARS에서도 저장 10일째에 OSE4 처리구가 CON과 ISE2 처리구와 비교하여 유의적으로 낮게 나타났다(p<0.05). 결론적으로, 비육돈 사료내 Se와 비타민 E를 첨가하였을 때 가열감량, 육색 및 지방산패도에 미치는 영향은 미미한 것으로 사료된다. This study was conducted to investigate the effect of seleium (Se) and vitamin E supplementation on meat quality and shelf-life in finishing pigs. A total of eighty ($Landrace{\times}Yorkshire{\times}Duroc$) pigs (74.74 initial BW) were randomly allocated into five treatments with four replications and fed for six weeks. Dietary treatments included 1) CON (basal diet), 2) ISE2 (basal diet+0.2 ppm inorganic Se+100 ppm vitamin E), 3) ISE4 (basal diet+0.4 ppm inorganic Se+100 ppm vitamin E), 4) OSE2 (basal diet+0.2 ppm organic Se+100 ppm vitamin E) and 5) OSE4 (basal diet+0.4 ppm organic Se+100 ppm vitamin E). Cooking loss was decreased in treatment of ISE4 as compared with treatment of CON (p<0.05). Crude fat (%) of OSE2 was higher than those of others (p<0.05). Redness ($a^*$- value) of M. longissimus dorsi was increased in treatment of OSE2 as compared with other treatments after 100 of storage (p<0.05). Thiobarbituric acid reactive substances (TBARS) was decreased in treatment of OSE4 compared with treatments of CON and ISE2 after 10d of storage (p<0.05). In conclusion, Se and vitamin E combination did not significantly affect cooking loss,$a^*$- value and TBARS except for cases.

This paper describes a processing verification technique for developing about end-milling cutters. Developed software is processing verification module for manufacturing. By using cutting simulation method, we can obtain center points of grinding wheel via Boolean operation between a grinding wheel and a cylindrical workpiece. The obtained CL data can be used for calculating NC data. After then, we can simulate by using designed grinding machine and NC data. This research has been implemented on a commercial CAD system by using the API function programming. The operator can evaluate the cutting simulation process and reduce the time of design and manufacturing.

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).
