This research was conducted to obtain basic data with regard to the heating performance that would be produced by installing an aluminum hot water pipe inside the greenhouse with the goal of reducing the heating energy in greenhouse. The research results are summarized as follows. The degree of difference in relation to the temperature by height within the greenhouse during the entire experiment was significant - within the range of 4.0~7.0℃. The temperature difference between incoming and outgoing water was about 3.3℃ greater when FCU was activated compared to when it was not activated. Meanwhile, the amount of energy consumed increased about 36.2~40.1%. The amount of pyrexia per hour also increased by 44.6~52.0%. During the experiment period, circulated flux was within the range of 0.48~0.49 L · s<SUP>?1</SUP> while average fluid speed was 1.53~1.56 m · s<SUP>?1</SUP>. The average temperature difference between incoming and outgoing water was 6.24~11.50℃. The amount of heating value by each set temperature within the minimum outdoor temperature range of ?14.0~?0.6℃ was 135,930~307,150 ㎉, and the range was within the 9,610~19,630 ㎉ · h<SUP>?1</SUP> per hour. This demonstrated that about 23~53% heating energy of the maximum heating load could be supplied. Total radiating value and amount of energy consumed were 2,548,306 ㎉ and 3,075.7 ㎾h, respectively. When heating takes place using oil, which is a fossil fuel, the total amount of light oil consumed was 281.6 L while the cost was 321,000 won. When the electricity cost for farms is applied, the total cost was about 110,730 won, which is about 33.5% of the cost required compared to oil consumption. The temperature at in the experiment area was about 8.3~14.6℃ higher compared to that of the control area.

Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.

( Mina Kang ),( Jihye Kim ),( Tae-joong Kim ),( Jeong-won Lee ),( Byoung-gie Kim ),( Duk-soo Bae ),( Chel Hun Choi ) 대한산부인과학회 2020 Obstetrics & Gynecology Science Vol.63 No.2

Objective To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi’s LM) and conventional 4-port LM. Methods A retrospective study of patients who underwent Choi’s LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with <3 symptomatic myomas sized <10 cm each and operated on by a single surgeon were included. Recurrence was confirmed when a myoma measuring ≥3 cm was detected. Results The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8±1.5 cm vs. 7.0±1.6 cm; P=0.40). In Choi’s LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi’s LM (3.4±0.7 cm vs. 5.7±2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. Conclusion Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi’s LM were acceptable. Considering its usability, Choi’s LM is feasible for the treatment of uterine leiomyoma.

Lee, Kang Soo,Choi, Sun Young,Choi, Won Yul 전북대학교 농업과학기술연구소 2000 農大論文集 Vol.31 No.1

Rice direct seeding on flooded paddy has a shortcoming of instability of seedling establishment due to hypoxia. This study was conducted to clarify the interrelationship between seeding rate and seedling growth in flooded condition and find out a optimum screening condition for anaerobic tolerant cultivars. The germinated seeds were sown in 250 ml flasks containing 150 ml (in water) and 5 ml distilled water(in air) at 25℃ respectively. The number of seeds sown (seeding rate) were 5, 15, 25, and 35 seeds per 250 ml flask. The characteristics measured, length of shoot and root, fresh weight of shoot and root and chlorophyll content, were not affected by seeding rate and cultivars in air while those in water were decreased as seeding rate increased. The dissolved oxygen in the soak water were affected by seeding rate and cultivars. The difference between the two cultivars in the characteristics were greatest when seeding rate was35 seeds in 250 ml flask containing 150 ml water. The characteristics at seeding rate of 35 seeds in 250 ml flask containing 150 ml water would be used in the screening of anaerobic tolerant cultivars for direct seeding.

Choi, Jae-Won,Kang, Dong-Ku,Park, Hyun,deMello, Andrew J.,Chang, Soo-Ik American ChemicalSociety 2012 ANALYTICAL CHEMISTRY - Vol.84 No.8

<P>Droplet-based microfluidic systems have emerged as a powerful platform for performing high-throughput biological experimentation. In addition, fluorescence polarization has been shown to be effective in reporting a diversity of bimolecular events such as protein-protein, DNA-protein, DNA-DNA, receptor-ligand, enzyme-substrate, and protein-drug interactions. Herein, we report the use of fluorescence polarization for high-throughput protein-protein interaction analysis in a droplet-based microfluidic system. To demonstrate the efficacy of the approach, we investigate the interaction between angiogenin (ANG) and antiangiogenin antibody (anti-ANG Ab) and demonstrate the efficient extraction of dissociation constants (K-D = 10.4 +/- 3.3 nM) within short time periods.</P>
