Evaluation of Preprocessing Techniques for Tumor Classification Using Numerical Dataset
Harun Ur Rashid(하룬 우르 라시드),Seong-Ho Jeong(정성호) 한국통신학회 2022 한국통신학회 학술대회논문집 Vol.2022 No.2
It is commonly recognized that the performance of any prediction model is highly dependent on a variety of parameters. The preprocessing approach is one of the most significant ways for data analysis. Furthermore, preprocessing is a crucial step in developing an efficient and successful classification model. The purpose of this paper is to determine the effect of the most generally used preprocessing approaches on the performance of classification algorithms with regard to numerical features. The effect of combining various normalization approaches and strategies for handling missing values is evaluated using a well-known classification algorithm on a privately gathered breast cancer dataset. According to the stated experimental results, the influence of the preprocessing techniques used varies depending on the combination of preprocessing techniques used.
Mycobacterial infections in solid organ transplant recipients
Harun Ur Rashid,Nura Afza Salma Begum,Tasnuva Sarah Kashem 대한이식학회 2021 Korean Journal of Transplantation Vol.35 No.4
Mycobacterium tuberculosis (MTB) infection in solid organ transplant (SOT) recipients remains a major challenge for physicians and surgeons. Active tuberculosis (TB) is associated with increased morbidity and mortality in SOT recipients. MTB usually develops after transplantation in a recipient with latent TB infection (LTBI) before transplantation and may also be transmitted from the donor or acquired from the community. Therefore, screening for LTBI in donors and recipients before transplantation is very important in preventing active disease after transplantation. This review article is based on recently published data, case series, and expert recommendations. We reviewed updated information about the epidemiology, diagnosis, and treatment of latent and active TB before and after transplantation. We also reviewed recent treatments for multidrug-resistant TB.

Background: Cervical cancer is a major public health problem in Bangladesh. Persistence of high risk human papillomavirus (HRHPV) influences the progression of the disease, with an important role in followup for cervical intraepithelial neoplasia (CIN). Objective: To establish application of high risk HPV DNA test in the follow-up of women after treatment of CIN. Materials and Methods: This cross-sectional and hospital based study was carried out among 145 CIN treated women during the previous six months to three years at the colposcopy clinic of Bangabandhu Sheikh Mujib Medical University, Dhaka, between January 2011 and June 2012. Pap smear and HPV samples were collected and colposcopy was performed to find out the persistence of the disease. Cervical samples obtained were tested for HPV DNA using the Hybrid Capture II (HC-II) test. A cervical biopsy was collected whenever necessary. The results were compared to assess the efficacy of different methods during follow up such as Pap smear, HPV test and colposcopy. Results: Mean age of the recruited women (n=145) was 33.6 (${\pm}7.6$), mean age of marriage was 16.8 (${\pm}2.9$) and mean age of 1st delivery was 18.8 (${\pm}3.5$) years. More than half had high grade CIN before treatment and 115 (79.3%) women were managed by LEEP and 20.7% were managed by cold coagulation. Among the 145 treated women, 139 were negative for HPV DNA and six of them (4.1%) were HPV positive. Sensitivity of Pap smear (40.0) and HPV DNA test (40.0) was poor, but specificity was quite satisfactory (>93.0) for all the tests. Conclusions: The high risk HPV DNA test can be an effective method of identifying residual disease. It can be added to colposcopy and this should be applied to all treated women attending for their first or second post-treatment follow-up visit at 6 months to one year, irrespective of the grade of treated CIN.

The coronavirus disease-19 (COVID-19) pandemic has affected 1,029,968 people in Asia as of May 16, 2020. Although Asia was the first continent to be affected, many countries in the region continue to battle COVID-19, which challenges the way transplant programs provide their services. Given the diversity of healthcare systems in Asia, the countermeasures in response to COVID-19 are as potentially diverse. This review reports the experiences of transplant services in member countries of the Asian Society of Transplantation (AST) as well as provides a platform for sharing of best practices during the COVID-19 pandemic. AST invited member countries to provide a short description of their transplant experiences during the COVID-19 pandemic. Whenever information is available, countries were asked to provide information on COVID-19 related statistics, status of transplant programs, mitigation measures taken to prevent COVID-19, and other areas of transplant programs impacted by COVID-19. Ten countries responded to the invitation of which seven still have active transplant programs at varying levels of activity. All countries have protocols for donor/recipient screening and countermeasures to prevent COVID-19 infections in recipients and healthcare providers. Interestingly, these countries report only 16 transplant recipients with COVID-19 infection but no cases of donor-transmitted COVID-19 infection. Despite the diversity of healthcare systems in Asia, transplant centers in Asia have taken appropriate precautions to avoid COVID-19 infections, though the long-term impact of COVID-19 remains unclear.

The study examines the impact of corporate governance mechanisms, such as board characteristics on corporate social responsibility disclosure (CSRD). The data on CSRD items and board characteristics have been collected by content analysis of the annual reports of 30 publicly-listed banks in Bangladesh covering six years, from 2013 to 2018. More specifically, the directors' report, the chairman's statement, notes to the financial statement and CSR disclosure reports included in annual reports were used to collect the CSRD data. The empirical analysis applies the ordinary least square and the generalized method of moments. The results of the study have revealed that board size, board independence, female board member, and foreign directors have a significant positive impact on CSRD. By contrast, political directors and audit committee size have a negative impact on CSRD. Interestingly, accounting experts on boards ensure more CSRD as they curb the influence of politicians on the board. Thus, it is better to increase accounting experts and decrease politicians on the board. These findings provide valuable insights into the process of forming a suitable CSR policy by connecting the efforts of the board, government, and regulatory bodies to enhance the performance of banks to CSR as well as to CSRD.
