목적: 초기 자궁내막암의 수술적치료 시 복강경유도하 질식 자궁절제술 및 골반림프절절제술군과 복식수술군의 수술결과 및 재발율에 대해 비교하고자하였다. 연구 방법: 2003년 3월부터 2005년 5월까지 초기 자궁내막암 환자를 인구학적 특성이 같은 63명을 선택하여 복강경유도하 질식 자궁절제술 및 골반림프절절제술군 26명, 복식수술군 37명으로 나누어 수술 전후 혈색소 차이, 평균수술시간, 취득한 골반림프절갯수, 평균재원일수, 추가치료율, 재발률을 비교하였다. 결과: 복강경유도하 질식 자궁절제술 및 골반림프절절제술을 시행한 군과 복식수술을 시행한 군과의 비교에서 수술 전후 혈색소 차이, 평균수술시간, 취득한 골반림프절 갯수, 평균재원일수, 재발률에 통계적으로 유의한 차이가 없었다. 결론: 초기 자궁내막암의 수술 시 복강경유도하 질식자궁절제술 및 골반림프절절제술 방법이 복식방법에 비해 수술결과 및 재발률에 통계적으로 유의한 차이가 없으며 그 대체 수술법으로 많은 활용이 기대되었다. Objective: To compare laparoscopic surgery with conventional abdominal surgery in patients with early stage endometrial cancer. Methods: A retrospective review of 63 patients with early stage endometrial cancer managed between March 2003 and May 2005. Two groups were defined whether they had been treated by laparoscopy (case group: n=26) or by laparotomy (control group: n=37). We compared age, body mass index (BMI), hemoglobin change, operation time, number of pelvic lymph nodes, hospital stay, case with adjuvant treatment and recurrence between two groups. Results: There was no statistical difference in characteristics (age, BMI, nulliparity, previous abdominal surgery, FIGO stage, histologic grade). between case and control group. In addition, there was no statistical difference in operation data and outcomes between two groups. Hemoglobin changes were 1.1 g/dL (case group) vs 1.7 g/dL (control group) (p=0.072). Operation time was 131 min vs. 115 min. The numbers of lymph nodes obtained were 8.7 vs 7.7 (right) 9.2 vs. 7.6 (left). Hospital stays were 8.4 vs. 9.2 days. Adjuvant treatment cases were 7 vs. 15. Recurrent case was one in each group. Two patients initially evaluated by laparoscopy were converted to laparotomy due to bleeding and adhesion. Conclusion: Laparoscopic surgery for treatment of early endometrial cancer is a safe and effective alternative to laparotomy . However, long-term survival and risk of recurrence have yet to be determined.

The purpose of this study was to find the characteristics of lateral cephalogram of skeletal class Ⅲ malocclusion patients to whom orthognathic surgery was essential. For this study 37 patients with skeletal class Ⅲ and going to treat or be treated orthognathic surgey(age7-17) were selected to experimental group and 56 people with normal occlusion (age8-13) were selected to normal group and the two groups were evaluated and statistically analyzed and the results were as follows 1. In comparison of experimental group and normal group in prepubertal group, there were significant differences in ANS-U1/Me-L1, Mx. Length/Mn. Length, S-N/Go-Me, Wits, ANB, SN-Pog, IMPA, Facial Convexity, APDI(p<0.05) 2. In comparison of experimental group and normal group in pubertal group, there were significant differences in ANS-U1/Me-L1, S-Go/N-Me, Mx. Length/Mn. Length, S-N/Go-Me, Wits, Saddle Angle, SNB, ANB, SN-Pog, IMPA, Interincisal Angle, Facial Convexity, APDI (P<0.05) 3. Among items showing characteristics of skeletal class Ⅲ malocclusion, there were no significant differences between prepubertal group and pubertal group in other items except Mx. Length/MN. Length, APDI (P<0.05) 4. The significant correlationship was the highest between Saddle Angle and SNB, SN-Pog and SNB, ANB and Facial Convexity in experimental group

This study aim to compare the effects of acute physical exercise on the serum enzyme, Creatine phosphokinase(CPK), Lactate dehydrgenaes(LDH), glutamic axaloacetic transaminase(GOT) and glutamic pyruvic transaminase(GPT) in two groups of Body Mass Index. The subject was divided two groups of 8 normal(BMI〈23) and 8 obesity (BMI〉30). The exercise consisted of running on a mater driven-treadmill until the subject reached exhaust. Blood sample were drawn from the antecubital vein before, immediately after exercise, postexercise 30 minute and postexercise 60 minute. Serum enzyme activity increase immediately after exercise the end of the tradmill test in the both groups for CPK(24.5%), LDH(15.3%), GOT(39.0%), and GPT(20.6%), and gradually decrease postexercise 60 minute to approximately to base activity. The serum enzyme activity significantly different between normal and obesity groups in before exercise of CPK(40.8%), LDH(14.7%), GOT(27.&%), and GPT(72.4%)(p〈0.05), and the immediately after exercise activity nonsignificantly different for CPK(29.0%), LDH(2.9%), GOT(8.1%), but GPT is significantly different(p〈0.05). It is concluded from this study that serum enzyme activity rise after exercise and recover to the base activity after postexercise 30 and 60 minute. It is indicate that sarum enzyme release to blood from skeletal muscle, tissue and organ. Obesity group's serum enzyme activity more higher than normal group is important pathological examination especially GOT, GPT.

Objective: To identify the effect of subcutaneous (SQ) drain on wound dehiscence and infection in patients who underwent midline laparotomy for gynecological disease. Methods: Patients planned to undergo midline laparotomy for gynecologic disease, BMI< 35, age >18 years and ECOG performance status 0-2 were 1:1 randomized to case (with SQ drain) vs. control (without SQ drain) at 9 institutes in Korea, from February 2021 to December 2021. We compared the incidence of wound dehiscence at 4 weeks post-surgery and cumulative incidence of wound dehiscence and infection up to 4 weeks post-surgery between case and control group. Results: Of the 174 randomized patients (case 84, control 90), 12 patients were dropped due to follow-up loss (case 5, control 7) and 162 patients (intention-to-treat [ITT] cohort: case 79, control 83) were included. Fourteen patients (case 10, control 4) did not follow assigned intervention depending on the operator’s decision because the SQ layer was either too thick or too thin, and were excluded from per-protocol [PP] analysis (case 69, control 79). In ITT cohort, the frequency of cancer surgery (63/79 [79.7%] vs. 64/83 [77.1%]; p=0.683) and surgery time (mean ± standard deviation = 227.7±133.9 minutes vs. 226.7±118.2 minutes; p=0.960) were comparable in the case and control group. Mean wound length was also similar in both groups (case vs. control; 24.2 cm vs. 24.3 cm; p=0.933). There were no significant differences in the incidence of wound dehiscence at 4 weeks post-surgery (1/79 [1.3%] vs. 2/83 [2.4%]; p>0.999), the cumulative incidence of wound dehiscence (7/79 [8.9%] vs. 5/83 [6.0%]; p=0.491), and the cumulative incidence of wound infection (1/79 [1.3%] vs. 0/83 [0.0%]; p=0.488) between case and control group. PP analysis showed similar result to ITT analysis. Conclusion: SQ drain insertion did not decrease wound dehiscence and infection in patients who underwent midline laparotomy for gynecological disease.
Learning of Cooperative Behavior between Robots in Distributed Autonomous Robotic System
Chel-Min Hwang,Kwee-Bo Sim 한국지능시스템학회 2005 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.5 No.2
This paper proposes a Distributed Autonomous Robotic System(DARS) based on an Artificial Immune System(AIS) and a Classifier System(CS). The behaviors of robots in the system are divided into global behaviors and local behaviors. The global behaviors are actions to search tasks in given environment. These actions are composed of two types: aggregation and dispersion. AIS decides one among these two actions, which robot should select and act on in the global. The local behaviors are actions to execute searched tasks. The robots learn the cooperative actions in these behaviors by the CS in the local one. The proposed system will be more adaptive than the existing system at the viewpoint that the robots learn and adapt the changing of tasks.
도메인 지식 반영 품셈 용어 사전 개발을 통한 신규 공종 공량 예측기법 연구

국가, 공공기관에서 발주하는 공사의 예정가격은 공사의 종류에 따라 거래실례가격, 표준시장단가, 견적가 등으로 산정되며 이중 전기 공사 등의 소규모 공사는 대부분 표준 품셈을 기준으로 산정되고 있다. 이 표준 품셈은 공사비 산정의 기준으로 발주기관과 시공업체의 이익에 직접적으로 연관된 중요한 자료이며, 대한전기협회 주관으로 제·개정 및 관리되고 있다. 하지만, 제·개정 절차는 복잡한 프로세스를 통해 이루어져 객관적이고 신속한 제·개정이 어려우며, 이로 인해 부정확한 공사비 산정을 유발하게 된다. 본 논문에서는 신속·정확한 품셈 제·개정에 도움이 되고자, 품셈 데이터의 분석 및 머신러닝, 딥러닝 기법을 활용하여 신규 공종의 공량을 예측하는 연구를 수행하였다.
