Multiple bilobar liver matastases (MBLM) are the main cause of low resectability in the colon cancer liver metastases. The authors experienced one case of initially non-resectable colon cancer liver metastases. He was curatively and safely treated with a two-stage hepatectomy using the new method of future remnant liver volume growing. A 54-year-old man was referred to our department with the sigmoid colon cancer combined with MBLM, which were checked in two small metastatic lesions in the left lobe and five large sized lesions in the right lobe in the computed tomogram (CT). A laparoscopic assisted anterior resection was primarily performed. We performed the 1^(st) stage hepatectomy 3 weeks after the colon resection. Intra-operative Ultrasonogram (US) found 9 small superficial metastatic lesions in the left lobe. All that lesions were completely removed by non-anatomical wedge resection. An occlusion ballon catheter was placed in the right portal vein through a small branch of the inferior mesenteric vein at that time. The future remnant liver volume was sufficiently increased 3 weeks after the 1^(st) hepatectomy. A right hepatectomy was safely performed 22 days after the 1^(st) hepatectomy. The patient received a regional chemotherapy (interleukin2 based immuno-chemotherapy through hepatic artery) for 4 months, then received 9 cycles of systemic chemotherapy (biweekly Oxaliplation, leucovorin, plus 5-fluorouracil) without any recurrence evidence.

This study is to review a change of characteristics and degree of preference for a mixture which is composed of skin of thorny ash tree, root of arrowroot, and an ingredient of samkyet'ang including extract of skin of thorny ash tree. For this study, a total of 45 broilers that are 4 weeks old are placed at each process area with 15 thorny ash tree chickens, 15 samkyet'ang chickens, and 15 average chickens. The test results for product development are such as; In the nutrition analysis, thorny ash tree chicken is analyzed to have protein of 10.07% to 11.08%. Thorny ash tree chicken has more fat than samkyet'ang chicken by 0.04% and has less fat than average chicken by 4.65%. As white-meat chicken, especially apart from red-meat, includes Omega-polyunsaturated fatty acids 3, 6 = ω -3,6) which is reportedly to have a growth function, reproduction function, treatment effect for arteriosclerosis and prevention effect for blood solidification, it is predicted to be continuously popular from gourmets. Relatively lime percentage is high and because of characteristics of cooking itself water still remains, so that the condition of nutrition can be kept which may be lost due to cooking. In the test of organic functions like<Figure 3-1, 2, 3>and<Table 3-7) the most important thing is the degree of preference of customers. If the visual aspect is a little bit corrected, this product will be a good one beyond description. Thorny ash tree chicken is evaluated to have sense of smell with 90% and taste with 97% degrees of preference from customers, organized degree with 83% from customers, and satisfaction degree with 97% from customers. Though it is thought that the visual aspect of thorny ash tree chicken is not a big problem as it has skin of thorny ash tree and root of arrowroot, ginseng, chestnut, garlic, jujube tree, gingko nut, ginger, red pepper, the only problem is our national consciousness about processed food and current economic atmosphere. The author hopes a product named thorny ash tree chicken will be fitted in with the $12,000 era of nation income.

추진호,조성호,강태호 中央大學校 建設環境硏究所 2002 環境科學硏究 Vol.13 No.2

터널 라이닝의 두께와 강성(stiffness)의 평가에 웨이브릿(wavelet)을 이용하여 신호 해석의 극대화와 터널의 건전도 평가에 있어서 직접적인 수직 균열의 유무, 위치, 다양한 반사면의 탐지에 관한 웨이브릿해석의 적용성을 평가하였다. 기존의 탄성파 해석은 시간 혹은 주파수의 한 영역에서만 해석이 이루어져 왔으나, Wavelet 해석은 신호처리에 있어서 시간-주파수 영역을 동시에 살펴보면서 해석을 할 수 있다. 본 연구에서는 콘크리트의 두께와 강성 균열을 평가하기 위하여 탄성파 기법의 하나인 충격반향 시험법에 대하여 Wavelet 해석을 시행하였다. 유한요소법의 하나인 ABAQUS를 이용한 수치해석과 실규모 현장시험체에서 시행한 실측 데이터 해석에 연속 Wavelet을 적용하여 보았으며, 그 결과 구조물 내에 존재하는 균열의 존재 여부와 균열의 위치를 확인하는데 Wavelet 기법이 매우 효과적이며, 향상된 신뢰성을 제공함을 확인하였다. The feasibility of the continuous wavelet analysis was evaluated for the nondestructive assessment of the structural integrity of a tunnel concrete liner. The conventional approach to analyze the signal of the wave propagation is focused on just one domain of time or frequency, while the wavelet analysis analyzes both domains of time and frequency. This study introduced the continuous wavelet analysis to interpret and analyze the stress-wave signal in both frequency and time domains for the better identification of the vertical cracks in the tunnel concrete liner. The synthetic stress-wave signals from ABAQUS were used to establish the methodology to employ the wavelet analysis, and later the real measurements at the real-scale tunnel concrete liner were analyzed. As a result, it was concluded that the continuous wavelet analysis is a reliable and effective tool to identify the vertical cracks in the tunnel concrete liner.

Streptococcus mutans는 구강 내에 상존하는 치아우식증의 주요 원인균으로서 치면의 피막에 부착 후 glucan을 형성하여 세균의 군락을 이루며, 외부로부터 공급된 자당대사를 통하여 유기산을 생성함으로써 법랑질을 탈회시킨다. 치아우식 활성도의 평가를 위한 단클론항체를 이용한 방법은 진료실에서 빠른 시간 내에 간편하게 타액에 존재하는 Streptococcus mutans의 정량분석이 가능한 방법이다. 이 연구는 3세에서 6세 사이의 어린이 15명을 대상으로 자극성 타액을 채취하여 시판 중인 단클론항체를 이용한 Salivacheck Mutans, strip을 이용한 Dentocult-SM 그리고 MSB배지 배양법으로서 타액 내 Streptococcus mutans를 측정한 후 그 값을 우식경험치아수와 비교하여 상관관계를 알아보았다. Saliva-check Mutans를 이용한 방법은 Dentocult-SM과 MSB배지법과 통계학적으로 유의한 상관관계를 보였으나 (p<0.05), MSB배지법은 어린이의 우식경험치아수와 통계학적으로 유의한 결과를 나타내지 않았다 (p=0.34). Streptococcus mutans, one of the major causal agents of dental caries, is component of the dental plaque. It produces various organic acids such as lactic acid which is the end-product of glycolysis, and this leads to dental caries. A new system using species-specific monoclonal antibodies was developed to detect Streptococcus mutans in saliva. The system quickly detects salivary Streptococcus mutans in 30min and classifies the result into two levels. The purpose of this study was to investigate correlation between monoclonal antibody-based detecting system and selective medium-based detecting methods. Children's deft indices were also compared with Streptococcus mutans counts in MSB agar plate. Subjects consisted of 15 children in the age of 3 to 6 years. They were assigned to three groups: Group Ⅰ (deft index = 3), Group Ⅱ (deft index ≤ 3), Group Ⅲ (deft index ≥ 4). The results are as follows : 1. The rate of children with positive response was 13.3% and with negative response was 86.7% in the result of Saliva-check Mutans test kit. 2. There was a positive correlation between monoclonal antibody-based detecting system and selective medium-based detecting methods (p<0.05). 3. Streptococcus mutans counts in MSB agar plate were irrelevant to deft of children(p=0.34).

A Modified irradiation technique utilizing a linear accelerator for radiation surgery within the brain was performed in 4 patients. Three of them had brain tumors and one small arteriovenous malformation in midbrain. A Hitchcock stereotactic apparatus and a 10 MeV linear accelerator have been adapted and special computer programs for dosimetry were obtained and studied experimentally with a phantom model. Stereotactic radiosurgery is a valuable tool in the treatment of inoperable, deep seated intracranial lesions, the major advantage being high efficacy and smoothness of the procedure, as well as short hospitalization times.

기하학적으로 대칭인 세 점의 움직임 벡터를 이용한 카메라 움직임 추정 기술

문성헌,한성우,박영민,장주석,윤영우 영남대학교 공업기술연구소 2001 工業技術硏究所論文集 Vol.29 No.1

This paper proposes a global motion estimation technique that utilizes the special relations of motion vectors of geometrically symmetrical triple points of frames. The proposed technique calculates several kinds of the parameters, such as panning, tilting, rolling, and zooming of camera motions at once by applying the proposed equation sets to the motion vectors only once, and avoids the trial and error method which the existent works have used. Moreover it discriminates against the foreground region and effectively reflects only the background region into the calculation of motion parameters, thus making the calculation more accurate and fast enough to accommodate MPEG-4 requirements. Experimental results on various types of sequences show the validity and the broad applicability of the proposed technique.
