'정상' 배추의 배축절편을 선발마커로서 paromomycin 저항 성유전자를 갖고 있는 pPTN290으로 각각 형질전환된 EHA101, LBA4404, GV3101균주와 공동배양한 후 갤러스유도배지에서 형질전환캘러스를 얻은 후, 뿌리유도배지에서 부정근을 그리고 신초유도배지에서 신초를 각각 순차적으로 유도하였다. 형질전환캘러스를 얻은 후, 뿌리유도배지에서 부정근을 그리고 신초유도배지에서 신초를 가각 순차적으로 유도하였다. 형질전환캘러스 형성은 Agrobacterium균주에 따라 차이가 있었으며, 특히 EHA101균주에 공동배양된 배축절편으로부터 최대 6.1%까지 얻어졌다. 또한 각각의 형질전환캘러스 클론으로부터 형질전환 부정근과 신초 발생은 EHA101균주에서 60.7%와 38.2%, LBA4404에서 8.3%와 0%, GV3101에서 20.5%와 85.7%까지 각각 얻을 수 있었다. 형질전환식물체는 특별한 형태적 이상 없이 온실에서 정상적으로 자라 $T_{2}$종자를 얻을 수 있었다. GUS방법으로 7개의 후대 유식물체를 분석한 결과 gus유전자가 안정적으로 발현하고 있음을 확인하였고, 배추 genome에 single 또는 multiple copy로 전달되고 있음을 추측할 수 있었다. Hypocotyl explants of Chinese cabbage (cvs. "Jeong Sang") produced transgenic calli on callus induction medium (MS salt, B5 vitamin, 5 mg/L acetosyringone, 1 mg/L 2,4-D, 3% sucrose, 400 mg/L cefotaxime, 100 mg/L paromomycin, pH 5.8) after cocultivation with strains of Agrobacterium tumefaciens (EHA101, LBA4404, GV3101) harboring the pPTN290 containing paromomycin-resistance gene as a selectable marker, and then they transferred to root induction medium (1/2MS salt, MS vitamins, 2% sucrose, 100 mg/L paromomycin, 100 mg/L cefotaxime, pH 5.8) and shoot induction medium (MS salt, B5 vitamin, 4 mg/L $AgNO_3$, 4 mg/L 6-benzyladenine, 3 mg/L alpha-naphthaleneacetic acid, 100 mg/L paromomycin, 100 mg/L cefotaxime, 3% sucrose, pH 5.8) in order. There was a significant difference in the frequency of transgenic calli depending on Agrobacterium strains. In particular, the highest frequency (6.1%) of transgenic calli was obtained from the hypocotyls cocultivated with EHA101 strains. Also, the frequency (%) of transgenic root and plants from each transgenic callus clone were obtained with 60.7% and 38.2% in EHA101, with 8.3% and 0% in LBA4404, with 20.5% and 85.7% in GV3101 strains, respectively. They were grown to maturity in a greenhouse and normally produced $T_2$ seeds. GUS histochemical assay for progeny ($T_2$) revealed that the transgenes was expressed in the plant genome, and progeny analysis from 7 independent transgenic events demonstrated that the transformants transmitted the transgene as a single or multiple functional locus.

( Sung Pil Hong ),( Tae Il Kim ),( Hyun Gun Kim ),( Hyun Soo Kim ),( Seong Eun Kim ),( Kyu Chan Huh ),( Jeong Eun Shin ),( Jae Myung Cha ),( Suck Ho Lee ) 대한장연구학회 2013 Intestinal Research Vol.11 No.4

Background/Aims: Recent guidelines strongly recommend that the interval of surveillance colonoscopy be determined according to the risk stratification obtained at index colonoscopy. However, because of the differences in perception of the classification of colorectal intraepithelial neoplasia between Asian and Western countries, there is some confusion about surveillance colonoscopy. The aim of the present study was to evaluate the clinicopathological characteristics and the interval of surveillance colonoscopy between patients with high-grade dysplasia/carcinoma in situ and those with intramucosal carcinoma. Methods: From January 2003 to June 2010, 727 patients were included from 8 tertiary centers. Four hundred fifteen patients (57.1%) had high-grade dysplasia /carcinoma in situ (group A), and 312 (43.9%) had intramucosal carcinoma (group B). Clinicopathological data were reviewed retrospectively. Results: Group A had a significantly more frequent family history of colorectal cancer (3.1% vs. 0.6%, P<0.001), smaller polyp size (12 mm vs. 15 mm, P=0.001), and more proximal location (31.1% vs. 21.8%, P=0.005) than did group B. Among 727 patients, surveillance colonoscopy was performed within 6 months in 55.8% of patients and within 12 months in 77.8%. Group B had a significantly shorter interval of surveillance colonoscopy than did group A (P<0.001). There was no difference in detection of advanced neoplasia at surveillance colonoscopy between the 2 groups (6.6% vs. 5.4%, P=0.638). Conclusions: The recommended interval of surveillance colonoscopy is not followed in Korea. More education about post-polypectomy surveillance guidelines is required. (Intest Res 2013;11:276-282)

Kim, Koung-Suk,Jang, Wan-Shik,Hong, Myung-Seak,Kang, Ki-Soo,Jung, Hyun-Chul,Kang, Young-Jun,Yang, Sung-Pil The Korean Society of Mechanical Engineers 2000 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.14 No.5

This study discusses a non-contact optical technique (electronic speckle pattern interferometry) that is well suited for thermal deformation measurement without any surface preparation and compensating process. Fiber reinforced plastics ($[0]_{16},\;[0/90]_{8S}$) were analyzed by ESPI to determine their thermal expansion coefficients. The thermal expansion coefficient of the transverse direction of a uniaxial composite is evaluated as $48.78{\times}10^{-6}(1/^{\circ}C)$. Also, the thermal expansion coefficient of the cross-ply laminate $[0/90]_{8S}$ is numerically estimated as $3.23{\times}10^{-6}(1/^{\circ}C)$ that is compared with that measured by ESPI.

The effect of maternal age on Cesarean delivery, maternal and perinatal outcomes following induction of labor in uncomplicated nulliparous women

( Sung Pil Choo ),( Yeo Jin Rhee ),( Jisun Yun ),( Eui Hyeok Kim ) 대한산부인과학회 2019 대한산부인과학회 학술대회 Vol.105 No.-

Objective: Women who give birth at 35 years of age or older are generally referred to advanced maternal age (AMA), which is risk factors for various kinds of complication besides genetic changes in fetus. The primary outcome is to determine if AMA is associated with emergent cesarean delivery (CD) following induction of labor (IOL). The secondary outcomes were a composite of adverse maternal and perinatal events following IOL. Methods: This was a retrospective observational study of singleton, vertex-presenting non-anomalous pregnancy from 37 0/7 to 41 6/7 weeks of gestation who were delivered following IOL in uncomplicated nulliparous women. After IOL, outcomes in women with AMA were compared with women < 35 years. Results: A total of 314 nulliparous women were attempted IOL (≥ 35 years n=73, 23.2%; < 35 years n=257, 81.8%) and among them, 257 (81.8%) delivered vaginally. The rate of CD was significantly higher in women with AMA (31.5% vs. 14.1%, p=0.001). Multivariable analysis showed that AMA was an independently associated with CD (OR 2.98, 95% CI 1.56-5.71, p=0.001). The rate of instrumental deliveries and the blood loss during the delivery were similar between the two groups (13.7% vs. 7.9%, 1.97±1.32 vs. 1.86±1.25 mg/dl, respectively, all p > 0.05). Regarding neonatal outcomes, there was no different between the two groups in NICU admission rate and Apgar score < 7 at 5 minute (38.4% vs. 31.5%, 12.3% vs. 7.6%, respectively, all p > 0.005). Conclusion: Following IOL, AMA was associated with a more than three-fold increased likelihood of birth by CD in nulliparous women. We found, however, no evidence that induced labor in elderly primigravida increases adverse maternal and neonatal outcomes as compared with women < 35 years.

The effect of Diagnosis-Related Group payment system on the quaility of medical care, among the patient diagnosed with pelvic organ prolapse in Korean Tertiary Hospitals

( Sung Pil Choo ),( Eui Hyeok Kim ),( Myung Jae Jeon ) 대한산부인과학회 2018 대한산부인과학회 학술대회 Vol.104 No.-

Objective: To examine changes in clinical practice patterns including the number of simultaneous surgeries for patients diagnosed with pelvic organ prolapse (POP) following the introduction of diagnosis-related groups (DRGs) payment system of the Fee-for-service (FFS) in July 2013 in Korean tertiary hospitals and to evaluate its effect on the quality of hospital care. Methods: Using the 20112016 administrative database from National Health Insurance Service claim data, we reviewed medical information for 8115 patients who underwent hysterectomy with the diagnosis POP in 43 tertiary hospitals. We compared changes in the number of simultaneous operations during hysterectomy and several variables in length of stay (LOS), spillover, readmission rate from before to after introduction of the DRGs for 2 and a half years respectively. Results: DRGs significantly reduced the number of simultaneous surgeries, such as colpopexies and transobturator-tape procedures using expensive mesh or tape, during hysterectomy (9.37% vs. 6.64%, 9.66% vs. 3.16% respectively, all p<0.001) while there was no significant difference in the number of colporrhaphy using simple absorbable suture materials during hysterectomy (21.35% vs. 23.09%, p=0.199). Readmission rate increased after DRGs (3.01% vs. 4.51% p< 0.001) and spillover rate did not change. LOS was reduced (7.4 ± 3.5 vs. 6.4 ± 2.7, p < 0.001) after DRGs. Conclusion: Implementation of DRGs in the field of urogynecology in Korean tertiary hospitals led to reduce the number of co-surgeries requiring expensive medical operative equipment while the number of those that did not remained the same. DRGs also led to increase the readmission rate and reduction the LOS without increasing outpatient visits.

Solution Vicosity and Relative Reactivity of Branched and Linear Polycarbonates

Kim, Sang Hern,Kim, Whan Gi,Kim, Sang Pil,Lee, Bong Hee 한국유화학회 2000 한국응용과학기술학회지 Vol.17 No.2

The relative reactivities of branched and linear polycarbonates were investigated by measuring unreacted chloroformate concentration. It was found that the polymerization for the branched polymer proceeded ca. 10 times faster than that for the linear polymers. The effect of catalyst on a condensation step was studied by changing the amount of TEA (triethylamine) at t_0 and t_60 with keeping constant amount of TEA. The viscosity average molecular weight for the obtained branched polycarbonates were measured and compared with those of linear polycarbonates. It was found that the viscosity molecular weights of the obtained polymers decreased nonlinearly as wt % of added oligomer increased. The solution viscosities in methylenechloride for linear and branched polycarbonate increased nonlinearly as the content of polymer increased.
