Background: To evaluate the efficacy of peri-urethral thrombin instillation at the surgical site after trans-urethral prostate surgery in benign prostatic hyperplasia (BPH), with the objective of reducing post-operative hematuria and preserving voiding function. Methods: The study was retrospectively analyzed a total of 122 patients who had trans-urethral prostate surgery between January 2019 and March 2023. Among these, 33 received thrombin instillation, while 89 did not receive it. In the test group, a mixture of 5 cc of saline solution and 5,000 IU of thrombin was instilled below the balloon, targeting the surgical site by inserting a 5 Fr feeding tube along with the Foley catheter. We compared hematologic data and uroflowmetry (UFM) between pre and post-operative periods, the duration of continuous bladder irrigation (CBI) and Foley catheter indwelling period. Results: The mean age and prostate size in the test group were 71.52±7.15 years and 54.05±24.73 g, while 71.38±8.22 years and 64.52±28.43 g in the control group. The prostate resected weight was 24.97±15.77 g and 27.58±17.00 g respectively. The hemoglobin and platelet levels were −1.05±0.81 g/dL and −42.79±35.59×103/L in the test group, and −1.08±0.97 g/dL and −27.93±40.49×103/L, in the control group. The test group showed better outcomes in CBI application time (21.31±12.15 hours) and Foley catheter indwelling time (50.97±14.63 hours) compared to the control group (34.42±22.68 hours and 70.33±33.95 hours) (P<0.001). Conclusion: After trans-urethral prostate surgery, thrombin agent instillation can prevent post-operative hematuria and facilitate quicker recovery to daily activities.

Previously, two events (H15 and B20) of transgenic pepper (Capsicum annuum L.) that enhanced resistance to Cucumber mosaic virus (CMV) by the introduction of CMV coat protein (CP) gene were constructed. Presently, a single copy number of the CP gene was revealed in H15 and B20 by Southern blot. To predict possible unintended effects due to transgene insertion in an endogenous gene, we carried out sequencing of the 5'-flanking region of the CP gene and a Blastbased search. The results revealed that insertion of the transgene into genes encoding putative proteins may occur in the H15 and B20 transgenic event. Mutiplex polymerase chain reaction (PCR) for simultaneous detection and identification of transgenic pepper was conducted with a set of nine primers. Both transgenic event were differentiated from non-transgenic event by the presence of 267 bp and 430 bp PCR products indicative of CP gene specific primer pairs and primer pairs targeting the CP gene and 35S promoter. H15 and B20 uniquely possessed a 390 bp and 596 bp PCR product, respectively. The presence of a 1115 bp product corresponding to intrinsic pepper actin gene confirmed the use of pepper DNA as the PCR template. The primer set and PCR conditions used presently may allow the accurate and simple identification of CMV resistant transgenic pepper.

Background: As all HLA class II genes, the DQ genes show their polymorphic variation mainly in the second exon, which encodes the first extracellular domain of the molecule. PCR-SSOP (Polymerase chain reaction-Sequence specific oligonucleotide probe) techniques were frequently used for HLA-DQA1 and DQB1 typing but certain alleles, $DQA1^*0101/0104/0105$, $^*302/0303$, $*0501/0505$ and $DQB1^*0201/^*0202$ which differ from each other in segment other than exon 2, could not be unequivocally assigned. Methods: To overcome this problem, we applied additional PCR-SSP (PCR-Sequence specific primer) method to analyze DQA1 exons 1, 3 and 4 and DQB1 exon 3. And we investigated the distributions and haplotypes of HLA-DRB1, DQA1 and DQB1 alleles in 406 unrelated Korean healthy individuals. Results: Using this method the indistinguishable alleles of DQA1 and DQB1 in PCR-SSOP were typed definitively. We also found several important associations between DQA1 and DQB1 alleles in the Korean population; $DQA1^*0101-DQB1^*0501$, $DQA1^*0104-DQB1^*0502$ or $-^*0503$, $DQA1^*0105-DQB1^*0501$, $DQA1^*0302-DQB1^*0303$, $DQA1^*0303-DQB1^*0401$ or $-^*0402$, $DQA1^*0501-DQB1^*0201$, $DQA1^*0505-DQB1^*0301$, and $DQA1^*0201-DQB1^*0202$. The haplotypes of DRB1-DQA1-DQB1 associated with $DQA1^*01$, $^*03$, $^*05$, and $DQB1^*02$ subtypes were investigated. Several haplotypes associated with these alleles were observed in the Korean population. Conclusion: Our results can be helpful to find potential unrelated donors for bone marrow registries and study the HLA-associated disease and anthropology at high-resolution allelic level.

This survey was conducted to obtain basic data about organic matter such as BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), DOC (Dissolved Organic Carbon) and TOC (Total Organic Carbon) in agricultural water in Gyeongnam province. BOD and COD are currently used for water quality indices, but adoption of TOC is being suggested. The surface water samples were collected at 39 locations in Gyeongnam province in April, July and October. Average concentrations of BOD, COD, DOC and TOC were 1.6, 3.3, 5.3 and 5.7 mg L<SUP>-</SUP>1, respectively. In July, average concentrations of BOD and COD were 2.4 and 3.9 mg L<SUP>-1</SUP>, respectively, showing these values were higher than other months. Average concentrations of TOC in April, July and October were 4.8, 7.4 and 4.8 mg L<SUP>-1</SUP>, respectively. This suggested that the highest value of TOC was in July. Average decomposition efficiencies for BOD-C/TOC and COD-C/TOC were 11.4 and 23.9%, respectively. Correlation coefficient of TOC and DOC was higher by 0.995, whereas that of TOC and COD was lower by 0.763. Especially, TOC and DOC were highly related than others.

A Study on the Treatment Method and Packaging Concept by of Radioactive Waste

Seong-Sik Shin,Jung-Hoon Choi,Jae-Young Pyo,Ki Rak Lee,Hwan-Seo Park,Hyun Woo Kang 한국방사성폐기물학회 2023 한국방사성폐기물학회 학술논문요약집 Vol.21 No.2

Radioactive iodine-129, a byproduct of nuclear fission in nuclear power plants, presents significant environmental and health risks due to its high solubility in water and volatility. Iodine-129, with its half-life of 1.57×1017 years, necessitates safe management and disposal. Therefore, safely capturing and managing I-129 during spent nuclear fuel reprocessing is of paramount importance. To address these challenges, various glass waste forms containing silver iodide have been developed, such as borosilicate, silver phosphate, silver vanadate, and silver tellurite glasses. These glasses effectively immobilize iodine, but the high cost of silver raises affordability concerns. This study introduces CuI·Cu2O·TeO2 glass waste forms for iodine immobilization, a novel approach. The cost-effectiveness of copper, in contrast to silver, makes it an attractive alternative. The CuI·Cu2O·TeO2 glass waste forms were synthesized with varying CuI content (x) in (1-x)(0.3Cu2O·0.7TeO2) glass matrices. Xray diffraction (XRD) confirmed amorphous structures, and X-ray fluorescence (XRF) quantified composition. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy provided insights into structural properties. Durability assessments using a 7-day product consistency test (PCT-A) and inductively coupled plasma-mass spectrometry (ICP-MS) revealed compliance with U.S. glass regulations, making CuI·Cu2O·TeO2 glasses a promising choice for iodine immobilization in radioactive waste.

Much progress has been made in an effort to improve accounting standards and strengthen the oversight of corporate financial reporting in the years following the 1997 financial crisis. The government decided to introduce the class action lawsuit in the capital market. The class action lawsuit is one of the most effective measures to improve the transparency of corporate accounting, but it may cause many problems due to the low level of reliability of financial reporting for the past periods in Korea. The Financial Supervisory Commission set the grace period of 2005 and 2006 for companies to revise the fraudulent financial statements of past periods before implementing the Class Action Lawsuit Act in the Capital Market. Many firms voluntarily disclosed fraud and revised financial statements for past periods in the grace period. Investors may be shocked at the voluntary disclosure of fraud. However, they may positively react to the disclosure because it is a signal of improvement in the transparency of the firms. It is an empirical research issue to analyze whether the capital market will positively interpret the disclosure and increase the reliability of accounting information of the firms after disclosing fraud. This study investigates weather the relevance of accounting information on market value is different after voluntary disclosure of fraud. Specifically, we compare the value relevance of accounting information between fraud firms and other firms. The results provide that the earnings and annual cumulative abnormal returns of fraud firms are not associated even after the voluntary fraud disclosure. In the analysis on the relevance of book value and earnings to the market value, however, the book value of all firms has a positive coefficient, while the earnings variable has a positive coefficient only in other firms. The adjusted determinant coefficients of other firms is found higher than those of voluntary fraud disclosure firms, which shows different relevance of earnings between fraud firms and other firms. The findings suggest that investors are not satisfied with the level of transparency of financial statements of the voluntary fraud disclosure firms even after the voluntary fraud disclosure. An alternate explanation is that the coefficient of earning variable of the voluntary fraud disclosure firms is insignificant because many fraud firms report net loss in the year.
