The armillary sphere, an astronomical observation device embodying the Orbital Heaven Theory of the Later Han Dynasty in China, holds both historical and scientific significance. It has been produced in various forms by many individuals since its inception in the era of King Sejong in the Joseon Dynasty. A prominent figure in this field was Nam Byeong-cheol (南秉哲, 1817-1863), known for his work 'Uigijipseol' (儀器輯說), published in 1859, which detailed the history, production methods, and usage of the armillary sphere. This text particularly highlights 21 applications of the armillary sphere, divided into 33 measurements, covering aspects like installation, time, and positional measurements, supplemented with explanations of spherical trigonometry. Despite numerous records of the armillary sphere's design during the Joseon Dynasty, detailed usage information remains scarce. In this study, the 33 measurements described in 'Uigijipseol' (儀器輯說) were systematically classified into six for installation, nineteen for position measurement, seven for time measurement, and one for other purposes. Additionally, the measurement methods were analyzed and organized by dividing them into the ecliptic ring, moving equatorial ring, and fixed equatorial ring of the armillary sphere. In other words, from a modern astronomical perspective, the results of schematization for each step were presented by analyzing it from the viewpoint of longitude, right ascension, and solar time. Through the analysis of Nam's armillary sphere, this study not only aims to validate the restoration model of the armillary sphere but also suggests the potential for its use in basic astronomical education based on the understanding of the 19th-century Joseon armillary sphere.

제품생산자동화를 위한 로봇제어

남부희,이상재,이석원 강원대학교 석재복합신소재제품연구센터 1996 석재연 논문집 Vol.1 No.-

본 연구에서 신경망 회로를 이용하여 토크계산제어기를 갖는 로봇 매니퓰레이터의 비선형성과 불확실성을 보상하는 제어기를 설계한다. 여기서 사용한 신경망 회로는 앞되먹임구조의 자율학습을 하는 제어기이며 Ishiguro등이 제안한 학습 데이터가 필요로 하는 감독학습 방법의 보상기제어기 구조보다 간단하다. In this research we research the controller using neural network to compensate for the nonlinearities and uncertainties of the robotic manipulators with the computed torque method. This neural network is used as the feed forward controller which is trained on-line by unsupervised learning and is simpler in the control scheme than the neural network controller proposed by Ishiguro et al. which needs the teaching signals of the neural network compensators and whose learning is supervised.

MMPI에 의한 알코올 의존의 통계적 아형분류

남궁기,조현상,김병천,현명호,안혜리,이희상,유계준 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.5

목적 및 방법 : 본 연구에서는 알코올 의존으로 진단된 남자 환자 75명을 대상으로 MMPI 점수를 이용하여 군집 분석으로 아형 분류를 시도한 후, 사회인구학적 특성과 음주와 관련된 변인으로 그 분류가 판별 타당성이 있는지를 알아보았다. 결 과 : 군집 분석 결과 전체 대상은 6(Pa)-7(Pt)-8(Sc) 프로파일의 정신병적 아형(21.4%), 2(D)-3(Hy)-1(Hs) 프로파일의 신경증적 아형(49.3%), 그리고 정상 프로파일 아형(29.3%)의 세 아형으로 분류되었다. 이 세 아형간의 연령, 학력, 결혼 상태, 음주로 인한 입원 경력, 주당 평균 음주 일수, 음주시 평균 음주량, 음주 시작 연령, 직계가족상의 알코올리즘의 가족력 유무의 차이를 비교한 결과 통계적으로 유의한 차이는 없었다. 결 론 : 본 연구의 결과는 통계학적으로 유의한 세 아형으로 분류되었으나 이 아형 분류가 판별 타당성을 갖추지 못했음을 시사한다. Obects & Methods : The authors tried to classify 75 male patients with alcohol dependence by using cluster analysis of their MMPI data, to identify the characteristics of each subtype classified through that process and to evaluate the discriminant validity of the classification. Results : The subjects were divided into 3 subtypes by K-means cluster analysis of MMPI scores : a psychotic subtype of 6(Pa)-7(Pt)-8(Sc) profile(21.4%), a neurotic subtype of 2(D)-3(Hy)-1(Hs) profile(49.3%), a normal subtype(29.3%). But, there were no statistically significant differences of age, educational level, marital status, admission history due to alcoholic problems, number of drinking day per week, average amount of ethanol consumed per drinking occasion, age at onset of drinking and family history of alcoholism among these three subtypes. Conclusion : It seems that the subjects with alcohol dependence could be classified into three subtypes with statistical significance, but this statistical classification does not constitute any evidence of discriminant validity.

원발성 중추신경계 임파종 : 치료 및 생존율 Treatment and Survival Rate

남도현,이상형,김동규,정희원,지제근,왕규창,김현집,최길수,한대희 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.3

The authors report on 17 patients having primary central nervous system(CNS) lymphomas between January, 1981 and August, 1992. All patients were treated at Seoul National University Hospital. Only three cases underwent surgery only and fourteen cases underwent surgery and radiation therapy with or without chemotherapy. There were no immunosuppressive patients. Sixteen patients were analyzed for survival studies, because one case was lost during follow-up. The median survival time(MST) was 26 months and one- and two-year survival rates for the 16 patients were 87.5% and 65.6% respectively. The rate of survival was analyzed according to possible prognostic factors ; age and sex, multiplicity and location of tumors, preoperative Karnofsky performance score(KPS), pathological subclassification, type of surgery, preoperative steroid therapy, postoperative adjuvant therapy, extent of radiation, chemotherapy and the degree of response to treatment at three months follow-up. Postoperative adjuvant therapy and the degree of response to the treatment correlated with survival. Fourteen patients who underwent postoperative adjuvant therapy had a median survival time of 63 months. The one- and two-year survival rates were 100% and 75% respectively compared to the MST of 1.5 months with survival rates of 0% and 0% retrospectively for the two patients who did not. A higher long term survival rate was observed in the group with better immediate responses. In nine of 16 patients with complete responses, the MST, one-, and two-year survival rates were 63 months, 100%, and 83% respectively. The authors suggest that preoperative application of steroids may be considered in case of clinically suspected primary CNS lymphomas. It is concluded that after obtaining the tissue diagnosis of primary CNS lymphomas, radiotherapy with or without chemotherapy should be performed until the complete response.

MWPC 위치검출기의 X-선 천체물리학에의 응용

남욱원,최철성,문신행,강희동 경북대학교 센서기술연구소 1990 센서技術學術大會論文集 Vol.1 No.1

1983 년경 국내에서도 과학탐사 로케트와 인공위성이 발사될 예정에 있으며 이에 따라 X-선 천체물리학을 위한 방사선 센서의 국내 개발이 시급히 요청되는 바이다. 따라서 현재 방사선계측에 많이 이용되고 있는 방사선 센서들 중 국내에서 개발되어온 MWPC위치검출기를 소개하고 인공위성 혹은 과학탐사로케트에 탑재되어 X-선 천체물리학연구에 이용될 경우 연구 개발되어 나가야 할 방향을 제시하고자 한다. Domestic sounding rocket and scientific satellite are scheduled to launch around 1993. The development of radiation sensor is required to observe X-rays coming from celestial bodies by the use of those space vehicleS. In this study we introduce the multi-wire position sensitive detector and the future works of onboard detector for X-ray astrophysics.

Alloxan 유발성 당뇨쥐에서 혈장의 지질과산화 및 항산화효소에 미치는 Caffeic Acid의 영향

南昌祐,黃成姬 同德女子大學校 1992 同大論叢 Vol.22 No.1

This research was aimed to investigate the effect of caffeic acid on lipid peroxidation and antioxidative enzymes in alloxan induced d·i·acetic rats. The first group was administrated to intraperitoneal with alloxan to induce the diabetic mellitus, the second and third group was inhected with thiourea and caffeic acid before alloxan injection, respectively. The physiological saline solution was treated as control. At 24, 48 and 72 after treatment, the levels of lipid peroxide in plasma were estimated and the activities of supeoxide dismutase, catalase and glutathione peroxidase in the erythrocyte were also evaluated. The results obtained were summarized as fallows ; 1. The lipid peroxide level of plasma in alloxan group showed higher than that of other groups. But there was no significant difference among thiourea, caffeic acid and control group. 2. The activities of superoxide dismutase of erythrocyte in alloxan group was significantly higher than the all other groups at 24 hours and 48 hours after injection but showed no significant difference at 72 hours. 3. There was no significant difference in activities of catalase and glutathione peroxidase of erythrocyte between all gorups.

南尙熙 대구보건대학 1983 대구보건대학 論文集 Vol.7 No.-

The measured Values of the Voc and Isc as a relative light intensity the spectral photo response made by using Vaccum-evaporated Cds-Cu₂S this film. The spectral photoresponse peak was observed at the wave length longer than the wave length corresponding to a band gap of Cds-Cu₂S. The spectral photo response compared to work which has been done based on the Cds-Cu₂S single crystal material.
