Investigating and comparing data of cancer cases of Chonnam University Hospital, a model hospital treating cancer patients in Kwangju District, and Korea Cancer Center Hospital, a representing hospital treating cancer patients in Sedul District, as shown in their annual reports from January 1990 to December 1997, results are obtained as the following: 1. The cumulative total of 52,546 cancer patients for 8 years in Seoul District, consists of 6,294 cases (11.98%) in 1990, 6,881 cases (13.10%) in 1991, 6,672 cases (12.70%) in 1992, 6,705 cases (12.76%) in 1993, 6,461 cases (12.30%) in 1994, 6,350 cases (12.08%) in 1995, 6,865 cases (13.06%) in 1996, and 6,318 cases (12.02%) in 1997. There was no increase or decrease notable in number of cancer patients for 8 years. 2. The cumulative total of 9,091 cancer patients for 8 years in Kwangju District, consists of 1,144 cases (12.58%) in 1990, 792 cases (8.71%) in 991, 692 cases(7.61%) in 1992, 892 cases (9.81%) in 1993, 1,306 cases (14.37%) in 1994, 1,233 cases (13.56%) in 1995, 1,608 cases (17.69%) in 1996, and 1,424 cases (15.66%) in 1997, Number of cancer patients rapidly increased in 1994. Change in number of cancer cases is scarcely noticed in Seoul Distirct, but somewhat extensive of change is noticed for these 8 years in Kwangju Distirct; average 10.08% increase every year, from 7.61% at the lowest to 17.69% at the highest. 3. The total of 52,546 patients in Seoul District, was classified by physical regions attacked, 12,238 cases (23.48%) at stomach, 8,375 (15.94%) at cervix & uteri,n6,294 (11.98%) at lung, and 5,608 (10.67%) at liver in order. Male patients were attacked at stomach, liver, lung, and colon and rectum in order, and female patients were done at cervix & uteri, stomach, breast, and liver in order. 4. The total 9,091 cancer patients in Kwangju District, was classified by physical regions attacked, 1,054 cases (16.54%) at stomach, 1,085 (11.93%) at liver, 972 (10.96%) at lung, 913 (5.75%) at cervix & uteri, and 456 (5.02%) at breast in order. Male patients were attacked at stomach, liver, lung, and colon & rectum, and female patients were done at cervix & uteri, stomach, and breast in order. Distribution pattern by physical regions did not agree with that of Seoul Dirstrict, but it was much the same each other when looking into it in division by sex. 5. Counting all 13,173 cancer patients in Seuol District by age, patients between 1 to 4 years old are 95 cases (0.72%), 5 to 14 years are 172 cases (1.30%), 15 to 24 years are 264 cases (2.00%), 25 to 24 years are 911 cases (6.92%), 35 to 44 years 2,010 cases (15.26%), 45 to 54 years are 2,732 (20.74%), 55 to 64 years are 4,238 cases (32.17%), and 65 years and older are 2,751 (20.88%). The most is found in the age between 55 to 64 years, in the age over 65 is the next found in number, and then comes the group of 45 to 54 years. So patients from 45 to 65 compose over 70%. 6. Grouping cancer patients in Kwangju District by age, patients between 1 to 4 years old are 35 cases (1.15%), 5 to 14 years are 45 cases (1.48%), 15 to 24 years are 66 cases (2.18%), 25 to 34 years are 136 cases (4.49%), 35 to 44 years are 339 (11.18%), 45 to 54 years are 579 cases (19.10%), 55 to 64 years are 1,001 cases (33.01%), and 65 years and older are 831 (27.41%). The most is found in the age between 55 to 64 years, and then comes the group in the age over 65, and then does that of 45 to 54 years in order. Those from 45 to 65 compose over 70% here too. That makes almost similar pattern of distribution of cancer patients in age groups. 7. Of the whole 100,715 cancer patients all over the nation in 1992, 6,672 cases (6.62%) are from Seoul District, and 692 cases (0.96%) are from Kwangju District. Cancer patients all over the nation are composed of 24,215 cases (24.04%) of stomach cancer, 10,647 cases (10.57%) of cervix & uteri cancer, 9,769 cases (9.70%) of lung cancer, and 9,620 cases (9.55%) of liver cancer in order. The whole 6,672 cancer patients in Seoul District in 1992 are composed of 1,450 cases (21.738%) of stomach cancer, 735 cases (11.12%) of lung cancer, and 675 cases (10.21%) of liver cancer in order. Of the whole 692 cancer patients in Kwangju District are 160 cases (23.12%) of stomach cancer, 110 cases (17.34%) of cancer at colon and rectum, and 81 cases (11.71%) of cancer at liver in order. By physical region, two districts show different pattern of distribution. In Kwangju District, stomach, the most frequently attacked region by cancer is followed by colon and rectum. 8. Of all 6,865 cancer patients in Seoul District, as methods to diagnose to detect cancer 4,737 cases (69%) were detected by histologic test at the primary cancer-struck area, 1,098 cases (16%) by clinical investigation, and 481 cases(7%) by cytodiagnostic test in order. In Kwangju District, 1,014 cases (63%) were diagnosed by histologic test at the primary cancer-struck area, 369 cases (23%) by clinical investigation, and 195 cases (12%) by cytodiagnostic in order. In both Seoul, and Kwangju Districts, histologic test at the primary cancer-struck area, and clinical investigation account for over 85% of diagnosing methods applied to detection of cancer.

심장 박동기 신호검출 알고리즘 개발을 위한 심파의 시간영역에서의 특성화

김정국,이승한,허웅 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

심장 박동기는 정상보다 느리게 박동하는 심장의 박동수를 정상적으로 유지시키는 데 효과적으로 사용되어 왔으나 최근의 관련공학 분야 및 의학 발전에 힘입어 진단기능 강화 및 지능화가 요구되고 있다. 현재까지의 심장 박동기는 자발적 심장근육 수축의 유무만을 검출하여 필요한 경우 전기자극으로 심근을 탈분극시켜 인위적 수축을 야기시키는 비교적 단순한 동작을 수행하였으나, 심방세동 검출, 역행성 p-파 검출, PAC 검출, PVC 검출, Q-T 간격 검출, anti-tachy 부정맥 제거 페이싱, 급성 심근 경색 검출 등 더욱 지능적인 진단 및 치료 기능이 요구되고 있다. 본 논문에서는 현재 사용중인 대역 필터에 의존하는 심파 검출방식을 개선하여 중요한 신호정보를 보전하는 신호 검출 방법을 개발하기 위하여, 심장 박동기 리드 터미날로부터 신호를 증폭하여 저장하고 동시에 현재 가장 많이 사용중인 심장 박동기 필터들로 처리하여 필터링 전후의 신호를 비교하고 특성화하였다.

산업용 로봇의 일정한 방향성 생성

이승황,양승한,박용국 한국공작기계학회 2001 한국생산제조학회지 Vol.10 No.2

In general, there are many degrees of freedom(DOFs) in industrial robot. So they have many poses of several special end-effector's positions and orientations. For that reason, industrial robots are used in a wide scope of industrial applica-tions such as welding, spray painting, deburring, and so on. In this research, an off-line continuous path planning method based on linear interpolation with parabolic blend is developed. The method safely maintains the constant orientation for base frame and end-effector's path within allowable error and minimizes the number of segments in path. This algorithm may apply to welding and painting in which the orientation is particularly significant. The simulation study of cartesian curve is carried out to show the performance of this algorithm.

홍성표,김국세,한승조,김길준,김충원,이준 조선대학교 전자정보통신연구소 2001 電子情報通信硏究所論文誌 Vol.4 No.2

The 3-D shape use to effect of movie, animation, industrial design, medical treatment service, education, engineering etc... But it is not easy to make 3-D shape from the information of 2-D image. There are two methods in restoring 3-D video image through 2-D image; First the method of using a laser; Second, the method of acquiring 3-D image through stereo vision. Instead of doing two methods with many difficulties, I study the method of simple 3-D image in this research paper. We present here a simple and efficient method, called direct calibration, which does not require any equations at all. The direct calibration procedure builds a lookup table(LUT) image and 3-D coordinates by a real 3-D triangulation system. The LUT is built by measuring the image coordinates of a grid of known 3-D points, and recording both image and world coordinates for each point; the depth values of all other visible points are obtained by interpolation.

High-power Accelerator for Environmental Applications

Seung-Han Kuk,Sung-Myun Kim,Won-Gu Kang,한범수,Nikolai K. Kuksanov,Kwang-Young Jeong 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.61

A high-power electron accelerator has been developed for environmental applications by EB TECH Co. Ltd. and BINP. This accelerator, which has double extraction windows, can deliver an electron beam with a power up to 400 kW at 1 MeV through 3 irradiators. Titanium foils are used as the window material and are cooled both by water and a blowing air jet. High voltages are generated through the inductions of the coils in the main accelerator body and SF_6 gases are used to protect against electrical discharges. The first such accelerator was installed in 2005 at the Daegu Dyeing Industrial Complex, Korea, for treating industrial wastewater from textile dyeing industries.
