        남궁재관,김덕중 서울産業大學校 産業大學院 1997 大學院論文集 Vol.5 No.-

        The stock-control is an important factor in reducing cost on the industrial spot. It is surely necessary that some part is keeping with fit and frequently using parts are preserved with proper quantities for sending out goods. But many stock goods are difficult to control. Particularly it is closely related to employ finance of company smoothly. The suitable stock quantities are surely necessary for producing goods. But it is harmful for stock quantities to be accumulated too muck for operating the company There are various kinds to solve this problem. But first of all, We can think out the standardization of productions After that we can have control with database given peculiar codes to standardized products. If it is a designed plan using standardized products from the design of products, We can easily inquire out the sorts and numbers if articles according to article code gained from designed plans and easily control products. Also if the designing plan is made by automatic planning program, we can conveniently produce the sorts and numbers of required articles by automatic planning program. If the database, the files and stock articles are employed together with automatic planning program, We can draw up not only the designing plans but also the detailed lists of required and the total stock. Therefore it can be widen much more the utility scope of program as well as the bushiness efficiency.

        한국인 집단의 적혈구 효소의 다형현상 및 유전적 변이

        이정주,남궁용 한국유전학회 1986 Genes & Genomics Vol.8 No.2

        Polymorphisms of six red cell enzymes were studied on unrelated individuals from three areas (Seoul, Kangreung and Cheju) of Korea by horizontal starch gel electrophoresis. There were two G-6-PD alleles, GdB^+ and GdB^-, in Korean populations. The allele frequencies of GdB^+ in males were 0.9723 in Seoul, 0.9689 in Kangreung and 0.9726 in Cheju. Three soluble GOT alleles, GOT¹_s, GOT²_s and GOT³_s, were found in Korean populations. The allele frequencies of GOT¹_s were 0.9832 in Seoul, 0.9852 in Kangreung and 0.9851 in Cheju. It was interesting to note that GOT³_s allele was detected in Korean populations. The frequencies of GOT³_s were 0.0049 in Seoul and Kangreoung, and 0.0030 in Cheju. In esterase D study, two common alleles, EsD¹and EsD²were found. Allele frequencies of EsD¹were 0.6702 in Seoul, 0.6640 in Kangreung and 0.6716 in Cheju. There were two common acid phosphatase alleles, AcP^a and AcP^b, in Korean populations. AcP^c allele which was common in Caucasoids and rare alleles were not found. The allele frequencies of AcP^a were 0.3930 in Seoul, 0.4071 in Kangreung and 0.3826 in Cheju. In LDH and MDH studies, only the normal phenotype and no variant type were found. No variant type was found in both enzyme systems. So, LDH and cytoplasmic MDH seem to be monomorphic traits in Korean populations. The gene frequencies and polymorphic phenotypes of the above red cell enzymes were discussed in comparison with the other populations.

        충전유동층에 있어서의 분립체혼합속도

        정우창,남궁식 한국화학공학회 1968 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.6 No.1

        In this work, the rate of lateral solid mixing in packed fluidized bed, packing porcelain sphere, telleret. and spiral type wire, was measured by method of internal wall with hole, proposed already by auther. It was found that the rate of lateral solid mixing in packed bed, corrected by void fraction of packings was in fair agreement with it in the ordinary fluidized bed.

      • The Results of Curative Radiotherapy for Carcinoma of Uterine Cervix

        Ryu, Ryeong,Chang, Gee Young,Namkong, Sung Eun,Bahk, Yong Whee,Shinn, Kyung Sub,Kim, Seung Jo,Suh, Tae Suk,Yoon, Sei Chul,Kang, Ki Mun CATHOLIC MEDICAL CENTER 1994 Bulletin of the Clinical Research Institute Vol.22 No.2

        One-hundred five patients with invasive carcinoma of the uterine cervix treated with curative radiotherapy from March 1983 through October 1989 at the Department of Therapeutic Radiology, Kang-Nam St. Mary's Hospital. Among them, 78 patients received radiotherapy alone and 42 patients treated with neoadjuvant chemotherapy followed by radiotherapy and 15 patients were lost to follow up. All patients had follow up from 2 to 106 months (median; 62 months). Age of the patients ranged from 32 to 79 years at presentation (median; 59 years). The overall 5-year survival rates was 50.8%, and the 5-year survival rates by stage ⅠB, ⅡA, ⅡB, ⅢA, ⅢB, ⅣA was 47.7%, 70.2%, 64.1%, 40.0%, 23.1%, 14.3%, respectively. The 5-year survival rates was noted 51.2% of radiotherapy alone and 50.4% of neoadjuvant chemotherapy followed by radiotherapy. The overall failure rate was 18.3% (22/120) including 11.7% (14/120) locoregional failure, 5.8% (7/120) distant metastasis and 0.8% (1/120) locoregional failure with distant metastasis. Treatment failure rates by the stages were 15% (3/20) in stage ⅠB, 10.5% (2/19) in stage ⅡA, 10.2% (5/49) in stage ⅡB, 20% (1/5) for stage ⅢA, 61.5% (8/13) in stage ⅢB, and 28.6% (4/14) in stage ⅣA. The overall complication rate was 34.2% (41/120), including wet desquamation 7.5% (9/120), diarrhea 6.7% (8/120), radiation proctitis 5.8% (7/120) in decreasing order. A multivariate analysis of factors influencing the survival showed patient age (P=0.0291), FIGO stage (P=0.0001), Karnofsky performance status (P=0.0043), initial hemoglobin level (P=0.0001), and intracavitary radiation (P=0.0004), but, no significancy in histology (P=0.29) and teatment method (P=0.87).

        Performance Comparison Between Harmonically Mode - Locked Ring and Figure - of - Eight Type Fiber Lasers

        Kyong Hon Kim,Hak Kyu Lee,Min-Yong Jeon,El-Hang Lee,Cheol Soon Song,Ki Un Namkong 한국광학회 1996 한국광학회지 Vol.7 No.4

        We report on comparative results obtained from harmonically mode-locked laser operations of ring-type and figure-of-eight(F8) type erbium-doped fiber lasers by using a directional-coupler type electro-optic modulator as an active mode-locker. The mode-locked and transform-limited pulses of 10.6 ㎰ width were obtained at harmonics of the fundamental cavity frequency with the F8 type laser while mode-locked laser pulses greater than 15 ㎰ were achieved with the ring type laser.
