        Imaging technique or computer vision (CV) technology has received huge attention as a rapid and non-destructive technique throughout the world for measuring quality attributes of agricultural products including meat and meat products. This study was conducted to test the ability of CV technology to predict the quality attributes of beef. Images were captured from longissimus dorsi muscle in beef at 24 h post-mortem. Traits evaluated were color value (L*, a*, b*), pH, drip loss, cooking loss, dry matter, moisture, crude protein, fat, ash, thiobarbituric acid reactive substance (TBARS), peroxide value (POV), free fatty acid (FFA), total coliform count (TCC), total viable count (TVC) and total yeast-mould count (TYMC). Images were analyzed using the Matlab software (R2015a). Different reference values were determined by physicochemical, proximate, biochemical and microbiological test. All determination were done in triplicate and the mean value was reported. Data analysis was carried out using the programme Statgraphics Centurion XVI. Calibration and validation model were fitted using the software Unscrambler X version 9.7. A higher correlation found in a* (r=0.65) and moisture (r=0.56) with ‘a*’ value obtained from image analysis and the highest calibration and prediction accuracy was found in lightness (r²c=0.73, r²p=0.69) in beef. Results of this work show that CV technology may be a useful tool for predicting meat quality traits in the laboratory and meat processing industries.

        SME sector’s success also depends on its employees’ job satisfaction as satisfied employees are likely to be more productive at the workplace and positively enhance SME business performance. Small and medium firms are the heart of the economy, and employees are the main and valuable asset for the SME firms. If SME business managers can increase employee satisfaction, then SMEs’ performance will also increase in the future. Hence, the current study aims to determine the job satisfaction of SME employees by analyzing the impact of job training (JT) and promotion (PRO) opportunities on employee job satisfaction. Purposive sampling is applied in the study, and 202 SME employees have participated as sample respondents. The final sample size is n = 202. SPSS 26.0 version is used to analyze the hypotheses. The study findings show that both job training (JT) and promotion (PRO) have a positive effect on SME employee job satisfaction. It does indicate that SME managers need to provide necessary training programs and timely promotion to their current working employees to keep them satisfied with their job. Promotion and effective job training will certainly enhance employees’ job satisfaction. The study has also offered a few strategic implications for SME business managers.

        Kidney disease is becoming a global public health issue. Acute kidney injury (AKI) and chronic kidney disease (CKD) have serious adverse health outcomes. However, there is no effective therapy to treat these diseases. Lactoferrin (LF), a multi-functional glycoprotein, is protective against various pathophysiological conditions in various disease models. LF shows protective effects against AKI and CKD. LF reduces markers related to inflammation, oxidative stress, apoptosis, and kidney fibrosis, and induces autophagy and mitochondrial biogenesis in the kidney. Although there are no clinical trials of LF to treat kidney disease, several clinical trials and studies on LF-based drug development are ongoing. In this review, we discussed the possible kidney protective mechanisms of LF, as well as the pharmacological and therapeutic advances. The evidence suggests that LF may become a potent pharmacological agent to treat kidney diseases.

        The primary objective of this study is to observe the impact of demographic factors on the job satisfaction of workers of the sugar industry in Bangladesh. Current research determines whether the age, level of education, marital status, and years of experience play a role in the job satisfaction of respondents and whether job satisfaction level differs among respondents in terms of age, level of education, marital status, and years of experience. A total of 300 respondents who are permanent production workers have been selected from state-owned sugar mills in Bangladesh on a random basis. A pre-structured questionnaire and for the information required face-to-face interview was conducted by the researcher. In analyzing data different statistical tools like Chi-square tests, ANOVA, Correlation were applied and data processed by using SPSS. The results of the present study revealed that a higher percentage of the high age workers was more satisfied with their present job than that of low age but statistically not significant. Other factors such as education, experience, and marital status, do not affect overall work satisfaction. The findings of this study suggest that the government and the concerned authority should draft proper policies and special programs to improve the level of satisfaction of sugar industrial workers.

        The implications of both entrepreneurial orientation (EO) and market orientation (MO) have been very critical in grasping business performance in terms of SMEs. Still, the research application of EO and MO on performance is not very abundant in a developing country perspective. Also, past studies did not take into account gender difference in understanding the performance of SME business in light of EO and MO. The research has been undertaken in Dhaka city, Bangladesh, as there is a number of SME businesses currently developing, which are expected to contribute to the economic progress by generating new employment and more opportunities. Hence, the ultimate objectives of the study are to examine the impact of EO and MO on performance of SMEs, along considering gender difference. 233 SME entrepreneurs responded to this study as survey respondents, followed non-probability sampling measure (n = 233). For analysis, SPSS software is used, through which correlation, regression, and ANOVA analysis were run. Results reveal that both EO and MO were strong predictors of SME performance, while no gender difference was noticed among EO and MO. Also, study findings suggest that enhancing and implementing EO and MO will heighten business performance of SMEs in Bangladesh context.

        This study was performed to assess the comparison of the effects amongst butylated hydroxytoluene (BHT), clove extract (CE), and ascorbic acid (AA) as antioxidants on the oxidative stability and color values in fresh beef patties. The adding of BHT, AA, and CE to patties significantly restrained lipid oxidation, lowered hue angle as color value, and expanded redness and chroma values of fresh beef patties in comparison to the control (p<0.05). BHT and AA significantly led to impede the protein oxidation of patties by lowering carbonyl content (p<0.05). CE had no negative effect on protein oxidation. The antioxidant effects of BHT, AA, and CE were obviously manifested. Nonetheless, BHT, AA, and CE appeared to have insignificant difference of each other for lowering the protein oxidation at the end of storage. BHT and CE represented lowered lipid oxidation in comparison to AA. The antioxidant effects of BHT, AA, and CE on lipid oxidation were more marked than the effects on protein oxidation. Furthermore, CE as a natural antioxidant evinced the efficiency in oxidative stability and color stability in fresh beef patties. The study implied that CE could substitute the use of BHT and AA when making beef patties during storage.

        Financial reporting includes disclosures as prescribed by regulators, but few companies go beyond mandatory requirements and provide additional information voluntarily. This study evaluates the potential impact of voluntary information disclosure on the value of firms listed on the Dhaka Stock Exchange for the period 2017–2019. The study applies GLS and system-GMM (Two-stage) estimation for detecting the magnitude of voluntary disclosure information on the firms’ value. Study findings reveal a positive and significant relationship between voluntary disclosure relating to financial statistics, social responsibility information, corporate governance, and the firms’ value as measured by Tobin’s Q. However, there is a negative and significant relationship between company information, accounting policies, and the firms’ value as measured by Tobin’s Q. Study findings suggest that the impact of voluntary disclosure on the value of the firms varies with the appropriate selection of proxy measures. Nonetheless, it is believed that voluntary disclosure plays a major role in projecting a clean image in the market and in attracting potential investors with a positive note about the company’s prospects.

        The study explores the empirical impact of foreign remittances on Bangladesh s household income and poverty indicators using the most recent wave of nationally representative household income expenditure survey (HIES)-2016 dataset. The goal of this study is to fill a vacuum in the empirical evidence on overseas remittances in Bangladesh. Using a two-stage Heckman selection model to account for selection bias and endogeneity caused by prospective migrants self-selection, the study finds that remittances boost household income and reduce poverty regardless of the measures employed. I find that in Bangladesh, overseas migration and remittances generate many of the expected positive outcomes for migrant-sending households. The evidence of the study suggests that boosting migration and remittances requires enhancing the level of education and skill of expatriate aspirants along with easily accessible financing for the rural poor, particularly farming households so that more people from poorer sections can participate.

          We present a new approach to typify object contours in a database by a reduced number of data points and to match object shapes in occluded conditions. For simplicity, contours are approximated by a set of quadratic Bezier curves and all control points are stored in the database. Initial contour segmentation procedure is carried out based on scale space parameters. The scale is chosen imposing the condition that a particular number of curvature zero-crossing points survive on the object contour for a longer period of its changes. Its value is neither too small nor too large so that the influence of noise effects and the loss of important features can be avoided. We introduce the distance matrix, which is constructed from curve to curve distance measurement between the test and database contours. The maximum alignment of distance matrix elements for their verification gives the total cost of similarity between the test and database contours. We present the experimental results to confirm the effectiveness of the proposed method and demonstrate the successful performance on object contours containing noise and occlusion.
