The Radiotherapy Result of Esophageal Cancer

정웅기,안성자,나병식,Chung, Woong-Ki,Ahn, Sung-Ja,Nah, Byung-Sik The Korean Society for Radiation Oncology 1991 Radiation Oncology Journal Vol.9 No.2

Ninety patients of esophageal cancer treated with radiation since November 1985 to June 1990 at the Department of Therapeutic Radiology, Chonnam University Hospital, were analysed retrospectively regarding survival. Seventy five patients ($94.9\%$) revealed squamous cell carcinoma in its histologic type, and most of patients were in advanced stage with 25 patients ($27.8\%$) of T2 and 64 patients ($71.1\%$) of T3. Minimum follow up period was 12 months and median was 5 months. Overall actuarial 2 year survival rate was $11.6\%$. Two year survival rates according to the parameters such as treatment aim, T stage, site, length, radiation dose and response were compared and resulted that survival by tumor length only had statistically significant impact on survival of esophageal carcinoma. 1985년 11월부터 1990년 6월까지 전남대학교병원 치료방사선과에서 방사선 치료를 받은 90예의 식도암 환자를 대상으로 생존율에 관하여 후향적 분석을 시행하였으며 다음과 같은 결과를 얻었다. 조직학적으로 75예 ($94.9\%$)가 편평상피 세포암으로 관찰되었으며, 병기는 25예 ($27.8\%$)가 T2, 64예 ($71.1\%$)가 T3로 대부분 진행된 암이었다. 최소 추적기간은 12개월 이었으며 중앙값은 5개월이었다. Kaplan Meier 법에 의한 2년 생존율은 $11.6\%$이었다. 치료목표, T병기, 병변부위, 병변길이, 방사선량, 관해정도에 따른 2년 생존율을 구하여 비교하였으며, 이들중 종양의 침범길이만 생존율에 영향을 미쳤다.

이진 분류기법을 이용한 24 GHz 실외용 도플러 레이더 모듈

정웅기,김충환,백동현 대한전자공학회 2019 전자공학회논문지 Vol.56 No.11

본 논문에서는 저가형 24GHz 도플러 레이더 모듈을 제작하였으며 실외에서 절전용 움직임 감지센서로 사용가능하도록 고안된 알고리듬을 적용하였다. 제안된 24GHz 도플러 레이더에 사용된 바이너리 분류 기법을 사용하여 주 감지대상인 보행자, 자전거, 자동차 등은 원하는 신호로 감지하면서 그 외의 외부환경에 의한 감지는 무시함으로서 오감지율을 줄였다. 제안된 알고리즘은 부수적으로 SNR을 개선하는 효과가 있어 감지대상에 대한 감지거리를 늘림으로서 실외 절전용 움직임 센서분야에 적용 할 수 있도록 하였다. 외부환경에 의한 오감지율이 충분히 작음을 확인하기 위해, 바람에 의하여 흔들리는 나뭇잎과 가로등 주변에서 날아다니는 곤충에 의한 오감지율을 실험하여 검증하였다. 보행자 감지거리 테스트 결과, 최소 30m 이상의 감지거리를 확인하였다. 24GHz doppler radar module has been fabricated for low-cost and an algorithm which can be used for the energy saving of outdoor lamps has been proposed. The proposed algorithm can differentiate targets such as pedestrians, moving bicycles and vehicles from false alarms caused by environments. By increasing SNR, detection range for targets can be increased and applied to outdoor power-saving motion sensors. In order to verify that false alarm rate by the external environment is small enough, false alarm rate has been tested against swaying trees by wind and flying insects nearby the radar. The detection range for the pedestrian has been found to be more than 30m.

합리적인 사찰경영을 위한 제언 -한국사찰의 미래지향적 포지셔닝 전략수립을 위하여-

Subject : Temple management, Buddhist community, Buddhist order, System of temple management, Reformation of buddhism Temple is like an organic body. Various resources are communicated by the medium of the space, and Buddhist cultures and customs of the time are created in the temples. The temple is like a bowl to put the contents of today`s Korean Buddhism in, and to express them. Although the status of Buddhism becomes higher, and how much the status of the religious body becomes stronger, the future of Buddhism must be dark if the temple becomes hollow and becomes to be dead place. From now on we must not postpone looking for the identity of the temple and making specialized model. he biggest crisis in Korean Buddhism of today is that the investigation of the identity of the temple- which is like a cell and a basic unit of Buddhism- is weak and the status of disorder of the premodern, modern, and post modern Buddhism is continuing because the investigation depends on the individuals. We must not support the blind fundamentalism of tradition, or becoming bigger which is no longer realistic under our circumstances. The appropriate modeling of the temple under our circumstances is urgently needed for us. If we can`t visualize these urgent tasks in the next few years, it will crumble soon however much we may try to praise the cultural capacity and the superiority of Buddhist doctrines. For the future oriented positioning, after we feel the pulse of macroscopic social change and look back over the path of the Korean temple objectively, we have to set up the model of rational management of the temple. The rational management of the temple needs to have a precondition of three elements like transparency, democracy, and social contribution, and on the other hand, it also needs to be approached by establishing a special identity appropriate to the circumstances of the individual temple.

The study was carried out to analyze the roentgenological findings associated with clinical symptoms and physical findings about 18 cases of congenital hydronephrosis confirmed at the Dept. of Urology, Chonnam National University Hospital from Jan. 1977 to Dec. 1981. The results were summarized as follows: 1. The congenital hydronephrosis developed mostly in male (89%) and the distribution of age was between 4 months and 34 years. 2. The incidence of pathologial side was 10 patients in left, 3 patients in right and 5 patients in bilateral. 3. The most common etiological factor was congenial UPJ stricture (33%), others composed of aberrant. renal vessel (22%), ureterocele (22%), posterior urethral valve (11%), fibrous band (6%) and renal fusion (6%). 4. The main symptom was flank pain (56%) and in 7 cases (39%) abdominal mass was palpable. 5. On laboratory examination, serum BUN and creatinine level were normal in 14 cases (78%) and 15 cases (82%) respectively. In 2 cases of posterior urethral valves, renal function was severely damaged. 6. Intravenous pyelography was performed in all cases and showed pelvicaliceal dilatation in 13 cases, non-visualizing kidney in 5 cases, and characteristic crescent sign in one case.

정웅기,안성자,남택근,나병식,김영진,Chung, Woong-Ki,Ahn, Sung-Ja,Nam, Taek-Keun,Nah, Byung-Sik,Kim, Young-Jin The Korean Society for Radiation Oncology 1992 Radiation Oncology Journal Vol.10 No.2

1982년 1월 부터 1990년 12월까지 전남대학교 병원에서 치료를 받은 95명의 직장암 환자를 대상으로 국소종양제어에 대한 수술후 방사선 치료의 역할을 알아보기 위하여 후향적 분석을 시행하였다. 95명의 환자중 72명은 수술만 받았으며 나머지 23명은 수술후 방사선 치료를 함께 받았다. 환자의 성별 분포는 남자가 45명 여자가 50명으로 비슷하였으며 연령의 중앙치는 53세 였다. 최소 추적기간은 19개월(범위 : $19\~125$)이었으며 중앙치는 47개월이었다. 종양의 국소재발율과 생존율은 Kaplan-Meier 법으로 계산하였으며 두 군간의 비교는 Log-rank test에 의하였다. 전체 95명의 환자중 27명 ($28.4\%$)에서 국소 종양의 재발이 관찰되었으며 13명($17.3\%$)에서는 원격 전이가 동시에 관찰되었다. 국소 종양 재발이 관찰된 27명중 24명 ($89\%$)이 수술 후 24개월이내에 재발되었으며 부위는 원발 병소 주위의 골반강내 조직에 가장 흔하였다. 수술만 받은 72명의 환자중 24명에서 국소 재발이 관찰되었다. 병기 A와 B1의 17명중 6명에서, B2와 B3 33 명중 7명 ($29.9\%$)에서, C2와 C3 19명중 11 명 ($54.7\%$)에서 각각 재발되었으며 병기에 따른 재발율의 차이는 통계학적 의의가 있었다(p<0.05). 수술후 방사선 치료를 받은 23명의 환자중 병기 B2와 B3 10명중 1명 ($10\%$)에서, 병기 C2와 C3 10명중 2명($22.2\%$)에서 재발이 관찰되었으며 두 군간의 차이는 통계학적 의의가 없었다(p<0.05). 한편 병기 B2와 B3에서 수술 후 방사선 치료를 시행한지 않은 군 보다 시행한 군에서 국소 종양 재발율이 낮았으나 통계학적 의의를 갖지 못하였으며 ($29.9\%$ vs $10.0\%$, p<0.05), 병기 C2와 C3의 경우는 수술 후 방사선 치료를 시행한 군에서 종양의 재발이 낮았으며 통계학적 의의가 있었다($34.7\%$ vs $22.2\%$, p<0.05). Ninety five patients of rectal cancer treated with surgery with or without adjuvant radiation therapy since January 1982 to December 1990 at the Chonnam University Hospital were analysed retrospectively regarding local failure. Of these 95 patients 72 patients were treated with surgery alone and remaining 23 patients received postoperative radiation therapy to pelvis. There were 45 men and 50 women with 53 years of median age. Minimum follow-up period was 19 months and median was47 months (range, 19-125 months). Kaplan-Meier method was used to calculate actuarial risk of local recurrence and survival rate. Comparison between two groups was evaluated by Log rank test. Of total 95 patients twenty seven patients ($28.4\%$) developed local recurrence and 13 patients ($17.3\%$) developed local and distant metastasis concomitantly. Eighty nine percent (24/27) of patients developed local recurrence within 24 months. Pelvic organ adjacent to the primary tumor area was the most common site of initial local recurrence. Of 72 patients treated with surgery alone local recurrence developed in 24 patients. Of 17 patients with stage A and 81 (Gunderson-Sosin modification of Dukes' staging system) 6 patients experienced local recurrence ($31.2\%$). The local recurrence rate of B2 and B3 group was $29.9\%$ (7/33) and that of C2 and C3 was $54.7\%$ (11/19), respectively. There was statistically significant difference between two groups (p<0.05). Of 23 patients treated with definitive surgery and radiation therapy $10\%$ (1/10) recurred in B2 and B3 patients. This was slightly lower than C2 and C3 patients ($22.2\%$, 2/10) of similar policy, but revealed no statistically significant difference (p>0.05). In the patients of B2+3 local failure rate decreased when radiation therapy was added ($29.9\%$ vs $10\%$, p>0.05) and also similar results in C2+3 group ($34.7\%$ vs $22.2\%$, p<0.05). The local failure rate in relation to distance from the anal verge had no statistically significant difference.
