This study was conducted to provide basic data for high-throughput screening (HTS) system construction based on phenomics. Rice (Oryza sativa cv. Chucheongbyeo) seedlings in vegetative growth stage were grown in the glass house and treated with 0, 3.75, 7.5, 15, and 30% (w/v) of polyethylene glycol (PEG) to give osmotic stress. Three days after PEG treatment, hyper-spectral reflectance images were obtained and analyzed after removing background image in several steps. The reflectance of rice seedlings treated with 15 and 30% of PEG solutions were significantly different at 680 nm, where differences in the chlorophyll reflectance spectrum and visual symptoms were not observed. These results thus indicate that hyper-spectral reflectance observed at 680 nm can be used to screen drought tolerant rice lines. A HTS system equipped with this hyper-spectral reflectance system may play an important role of future rice breeding program.

Objective: Congenital malformations of female genital tract have been associated with an increased rate of miscarriage, preterm delivery, poor obstetric outcome and risk of endometriosis. The aims of this study were to evaluate the prevalence of each type of congenital malformation and association of obstetric outcomes and endometriosis. Methods: All cases of congenital malformations of female genital tract were enrolled from January 2008 to April 2019 in Dongsan medical center. The prevalence of miscarriage, preterm birth and endometriosis in each types of anomalies were evaluated. Results: Three hundred five women were enrolled including MRKH (18 cases), unicornuate uterus (15 cases), bicornuate uterus (98 cases), uterine didelphys (73 cases), septate uterus (69 cases), transverse vaginal septum (6 cases), and imperforate hymen (26 cases). Common complaints were dysmenorrhea, infertility, amenorrhea, and miscarriage. Women complained of dysmenorrhea were diagnosed in the early age. Among 261 women performed laparoscopy, 74 women had endometriosis (28.3%). It was most prevalent in women with unicornuate uterus (66.7%), and also common in case of obstruction such as rudimentary horn and vaginal septum. In the 82 pregnant women, only 18 women had full-term birth. Miscarriage (34.1%) and preterm birth (43.9%) were happened regardless of the type of mullerian anomalies. Conclusion: Congenital malformations of female genital tract were related with the risk of miscarriage rate, preterm birth and endometriosis. Accurate diagnosis and meticulous management of congenital anomalies still remains a clinical challenge to prevent serious consequences of these patients.

Jin Won Kim,Tae-Young Lee,En-Su Park,Byoung Kwan Cho,Do-Soon Kim 한국육종학회 2013 한국육종학회 심포지엄 Vol.2013 No.07

This study was conducted to investigate plant body temperature response of soybean (Glycine max) to saline stress. Two-weeks-old seedlings of soybean in V1 growth stage were treated with 0, 10, 20, 40, 80 and 160 mM of NaCl for salt stress. Thermal images acquired using Flir T-420 (US) were obtained at 4 days after treatment. Soybean leaf temperature increased with increasing NaCl concentration, resulting in significant positive correlation between soybean leaf temperature and stress intensity (P < 0.01). Leaf temperature of soybean was significantly different at 160 mM of NaCl, where no visual symptom was observed. Therefore, soybean leaf temperature can be used for evaluating the response of soybean to salt stress as a non-destructive and phenomic parameter. Non-destructive diagnosis of soybean leaf temperature may be a key parameter in a high throughput screening (HTS) system in breeding program for salt stress tolerance soybean cultivars.

본 연구에서는 수성가스전환 고정층 촉매 멤브레인 반응기를 CFD(computational fluid dynamics)기술을 이용하여 해석했다. 수성가스전환반응에 대한 반응 속도식을 조사하고, 이를 모사할 수 있는 촉매 반응기 모델을 만들어 모사했으며 문헌치와 비교했다. 그리고 이에 합당한 반응속도식을 선정하고, 이를 이용하여 반응최적온도가 630 K임을 알아냈다. 수소 선택적 투과 멤브레인에 대한 CFD 모사 모듈을 개발하여 촉매 멤브레인 반응기에 대해 모사하고 문헌치와 비교, 분석했다. 멤브레인의 투과속도를 변화시켜 반응 전화율에 영향을 주는 변수들인 온도, 압력, 투과측 이송가스(sweep gas) 유속 및 흐름 방향, 멤브레인 두께를 가변시켜 해석했다. Results of the analysis of a catalytic membrane reactor for the water gas shift (WGS) reaction are presented and discussed using CFD (computational fluid dynamics) technique. Reaction kinetic expressions were researched, and Langmuir-Hinshelwood kinetic's expression gives the best result. The optimal operation temperature was found out to be 630K. A CFD module for the palladium (Pd) membrane, separating hydrogen, was also developed, simulated and compared to the references. It easily simulates the effects of the reaction temperature, pressure, sweep gas flow rate, sweep gas flow direction and palladium membrane thickness on the CO conversion of the catalytic membrane reactor. Results of the analysis are very useful in the commercialization of the hydrogen-generation process, and the developed simulation framework is easily adaptable for further design and modification when more detailed profiles are necessary.
