Hong Min Kim,Bong Seok Shin,Young Wook Song,Sang Mi Lee,Shin Hong Jung,Chang Won Kim,Ki Man Kang,In Sung Jung,Dong Jib Na 대한내과학회 2002 The Korean Journal of Internal Medicine Vol.17 No.1
Carcinosarcoma is defined as a malignant tumor with an admixture of carcinoma and sarcoma. Pulmonary carcinosarcoma accounts for about 0.27 percent of all lung neoplasms. It occurs frequently in males, particularly in smokers between 50 and 80 years of age
Transformation of Pisum sativum L. var sparkle; A Non Tissue Culture Method

완두에 있어서 보다 효율적인 형질전환 방법을 모색하고 형질전환된 개체를 얻고자 본실험을 수행하여 얻어진 결과는 다음과 같다. 형질전환은 발아중인 완두의 생장점(shoot tip)을 제거한 다음 T-DNA내에 GUS gene과 neomycin phosphotransferase Ⅱ gene이 들어있는 binary vector를 가진 Agrobacterium tumefaciens를 생장점을 제거한 부위에 감염시켰다. 감염후 새로 형성된 shoot는 개체당 4∼5개 였으며, 그중 GUS유전자가 발현하는 shoot만을 정상적인 식물체로 분화 시켰다. 감염부위에서 형성된 shoot에서의 GUS유전자의 발현빈도는 10%내외였다. 이들 개체로 부터 genomic DNA를 분리하여 Dot blot hybridization분석 결과 T-DNA가 식물체 내에 존재함을 알수 있었고, 수확한 종자를 발아시켜 Sorthern blot hybridization한 결과 T-DNA가 다음세대로 전달되었음이 확인되었으며 형질전환율은 2%이내였다. The transfer of genetic material into pea tissue was accomplished by using an avirulent strain of Agrobacterium tumefaciens containing the binary vector. The method used for transformation requires non-tissue culture steps as it involves the inoculation of the site of the shoot removed of germinating seeds. The identification of β-glucuronidase activity in the tissues of ?? pea plants indicates that the plant expressible β-glucuronidase gene, contained the T-DNA region from pLPBO2, had been transferred at least into somatic tissues. Putative transformed ?? pea plants were advanced to produce T₁plants which were also assayed for the presence of the transferred β-glucuronidase gene. The presence of the β-glucuronidase gene in DNAs isolated from T₁plant was demonstrated by DNA gel blot hybridization. This analysis revealed that the transformed plants contained β-glucuronidase gene.
진행성 비소세포 폐암에 대한 5 - Fluorouracil , Vinblastine 과 Cisplatin ( FVP ) 의 복합화학요법

N/A The 5 year survival rate after surgical resection for stage III non-small cell lung cancer(NSCLC) remains short, only 10-19%. Radiotherapy seems to show some benefit for local control, but it does not reflect to prolongation of survival, as distant metastasis prevails. Vinblastine is one of the most active agent against NSCLC. 5-Fluorouracil(5-FU) and cisplatin are synergistic in anti-cancer activity in adenocarcinoma of gastrointestinal tract and squamous cell cancer of head and neck. We initiated a phase II trial for advanced NSCLC to determine the effect of FVP regimen in response rate, survival and toxicities. The therapy consisted of 5-FU 500mg/m2/12 hours continious IV infusion for 36 hours from day 1, vinblastine 3mg/m2 IV bolus day 1 and 2, cisplatin 75mg/m2 IV infusion over 2 hours day 1 and it was repeated every 3 weeks. Among the 45 patients entered into this study, 40 patients were evaluable for response. The objective response rate was 50%(CR;1/40, 2.5% PRi19/40, 47.5%). The median survival of all the patients was 42.9 weeks(8.4+ - 140.6 weeks); the responding patients survived longer than the non-responders(mediansurvival; 54.4 weeks vs 29.7 weeks, p<0.05). The toxicities of this regimen were acceptable but 1 patient died of pneumonia associated with granulocytopenia. We concluded that the FVP regimen is effective in the treatment of advanced non-small cell lung cancer and a prospective randomized trial and long- term follow up is warranted.
Effect of Seeding Time on Fatty Acid Composition, Oil Contents and Seeds Yield in Flax
Choi, Hong Jib,Park, Shin Young,Kim, Sang Kuk The Plant Resources Society of Korea 2012 한국자원식물학회지 Vol.25 No.6
Influences of different seeding dates on growth, seed yield, fatty acid composition and oil content were investigated in flax plants for two years. The results indicated that plant height in early seeding date was higher than that of delayed seeding dates during first season. Furthermore, seeding date also significantly affected the ripened seed rate and the rate increased with the delay in seeding date in first season. Seed yield in the first crop season was significantly higher than the second crop season. Palmitic acid showed variation in different seeding dates. Contrarily, stearic acid was stable and did not changed by different seeding dates. Linolenic acid was found in highest amount in all seeding dates consecutively in two cropping years. Highest oil content was recovered from the seeds of flax sown at 29 Apr. and May 9 in first and second cropping year respectively.
보정 및 빔포밍 시간 최소화를 위한 묶음 REV와 최대값 보정 방법
윤홍집(Hong-jib Yoon),민병욱(Byung-Wook Min) 대한전자공학회 2017 대한전자공학회 학술대회 Vol.2017 No.6
In this paper, we proposed two new method. The fist method is bundle REV (Rotating electric-field vector), which significantly reduces the number of trials for array calibration. In the existing REV method, if array calibration is performed through N number of REV in the presence of N antennas, the proposed method can be reduced to logk N by combining k. The second method is the maximum value method, so that the total vector sum becomes the maximum when sweeping each element. In this way, we have confirmed that calibration and beam-forming times are minimized and that some accuracy is maintained.
Wideband 180° Phase Shifter Using Parallel-Coupled Three-Line
Yoon, Hong-Jib,Min, Byung-Wook THE INSTITUTE OF ELECTRICAL ENGINEERS 2019 Vol. No.
<P>In this letter, a wideband 180° phase shifter using a parallel-coupled three-line is demonstrated. The proposed phase shifter consists of a shorted coupled line and transmission line with shorted stubs. The bandwidth of the phase shifter is increased by a high coupling factor of the coupled line. When considering a coupling factor of 1, the bandwidth is infinite and the phase error is zero. Therefore, we adopted a parallel-coupled three-line to ensure a high coupling factor. Given a limited coupling factor, the transmission line impedance is optimized for the widest bandwidth of the return loss. The designed 180° phase shifter exhibits a return loss of less than −15 dB and a maximum phase error of less than 5° in the 1.14–2.79-GHz range and its fractional bandwidth is 83.9%.</P>
