A Comparative Analysis of Corporate Governance Guidelines: Bangladesh Perspective
Rahman,Md,Musfiqur,Khatun,Naima 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
The purpose of this research study is to make a comparative analysis between corporate governance guidelines 2006 and 2012 and area of further improvement to ensure better governance, accountability and transparency. This research study is mainly based on the corporate governance guidelines 2006 and 2012 issued by the regulatory authority known as Bangladesh Securities and Exchange Commission (BSEC). This study finds that corporate governance guideline 2012 include some new issues such as criteria and qualification of independent director; some additional statements in the directors report; mandatory requirement of separation of chairman and CEO; constitution of audit committee, chairman of audit committee; role of audit committee; duties of CEO and CFO on financial statements; and collection of compliance certificate from professional accountant or secretary in compare to corporate governance guidelines 2006. This study suggests that the regulatory authority should include more issues such as tax management and reporting, risk management and reporting; individual and overall performance analysis of the board and independent directors; separate nomination and compensation committee; assessment of true independence of the board and its supporting committees to ensure higher quality of corporate governance and transparency.

A thermophilic Bacillus stearothermophilus F1 produces an extremely thermostable serine protease. The F1 protease sequence was used to predict its three-dimensional (3D) structure to provide better insights into the relationship between the protein structure and biological function and to identify opportunities for protein engineering. The final model was evaluated to ensure its accuracy using three independent methods: Procheck, Verify3D, and Errat. The predicted 3D structure of F1 protease was compared with the crystal structure of serine proteases from mesophilic bacteria and archaea, and led to the identification of features that were related to protein stabilization. Higher thermostability correlated with an increased number of residues that were involved in ion pairs or networks of ion pairs. Therefore, the mutants W200R and D58S were designed using site-directed mutagenesis to investigate F1 protease stability. The effects of addition and disruption of ion pair networks on the activity and various stabilities of mutant F1 proteases were compared with those of the wild-type F1 protease.

A study was conducted for indentifying the floral biodiversity of woody species by calculating four diversity indices using data collected from 4 stands of different age groups and disturbance regimes in two areas of Madhupur tract. Results showed that highest species diversity in the old growth secondary coppice forest (>60 years) under moderate anthropogenic disturbances of Madhupur National Park area (delete (D=0.74, Hʼ=3.36) followed by old growth secondary forest stands (>40 years) under moderate disturbances at Bhawal National Park area (D=0.65, Hʼ=2.81). Plant species diversity of the young enrichment plantations (<20 years and <15 years) under high anthropogenic disturbances in both the areas are much low (D=0.54 and Hʼ=2.16 and D=0.52 and Hʼ=1.92 respectively), which indicate high anthropogenic disturbances coupled with introduction of invasive exotics that are rival for endemic species are detrimental for conservation of biological diversity of tropical moist deciduous forests of Madhupur tract in Bangladesh.

Rahman, M.M.,Rahman, M.Mashiar,Arafat, S.M.,Rahman, Atiqur,Khan, M.Z.H.,Rahman, M.S. The Korean Society for Applied Biological Chemistr 2008 Applied Biological Chemistry (Appl Biol Chem) Vol.53 No.4
Different types of milk products, such as kwacha golla, mawa, cheese, curd, and chocolate are popular in Bangladesh. However, the microbiological safety of these products is poorly understood. This study was performed to assess the microbiological quality of kwacha golla, a local milk product. Kwacha golla samples were collected from ten different areas of Rajshahi and Kushtia regions, and the quality of the each sample was assessed using various parameters including standard plate count, total coliform, fecal coliform, total fungi, and spore-forming bacteria, as well as food-borne microorganisms. Out of 300 samples, total coliform was detected at 56.66% (n= 300), exceeding the minimum allowable limit of 36.66%. Similarly, experiments were carried out with fungi and food-borne pathogens including Escherichia coli, Listeria monocytogenes, Salmonella sp., and Staphylococcus aureus. Results revealed 85.33, 53, and 49.33% of the samples were contaminated by fungi, E. coli, and L. monocytogenes, respectively. However, all samples showed no contaminations of Salmonella sp. and Staphylococcus sp. Therefore, this study could be helpful to the people of Bangladesh by providing information on the possibility of a major health problem caused by the consumption of kwacha golla.

Ashwagandha is an important ancient medicinal crops, being affected with many diseases, among which leaf blight caused by Alternaria alternata has become the constraint resulting in huge yield losses. Continuous usage of chemical methods leads to environment, soil and water pollution. Whereas biological control of diseases is long lasting, inexpensive, eco-friendly and harmless to target organisms. In this context, it is aimed to evaluate five Trichoderma strains viz. Trichoderma virens IMI-392430, T. pseudokoningii IMI-392431, T. harzianum IMI-392432, T. harzianum IMI-392433 and T. harzianum IMI-392434 as bio-control efficacy against A. alternata and growth promoting effect in Ashwagandha. All the Trichoderma strains had varied antagonistic effects against the pathogen. In dual culture technique, the strain T. harzianum IMI-392433 showed maximum percentage inhibition of mycelial growth (54.89%) followed by T. harzianum IMI-392432 (53.83%), T. harzianum IMI-392434 (48.94%) and T. virens IMI-392430, (43.62%) against the pathogen, while the least inhibition percentage was observed with the T. pseudokoningii IMI-392431 (36.60%). The culture filtrate of the Trichoderma strain, T. harzianum IMI-392433 recorded highest inhibition on the mycelial growth (39.05%) and spore germination (80.77%) of pathogen and the lowest was recorded in T. pseudokoningii IMI-392431 (20.45 and 50%). Moreover, seeds treated with spore suspension of the strain T. harzianum IMI-392433 reduced the percentages of disease severity index significantly. The strain T. harzianum IMI-392433 also significantly increased seed germination %, seedling vigor and growth of Ashwagandha. The correlation matrix showed that root yield per plant of Ashwagandha had significant and positive correlation with plant height (r=0.726**), number of leaf (r=0.514**), number of primary branch (r=0.820**), number of secondary branch (r=0.829**), fresh plant weight (r=0.887**), plant dry weight (r=0.613**), root length (r=0.824**), root diameter (r=0.786**), root dry weight (r=0.739**) and fresh root weight (r=0.731**). The significant and negative correlation (r=-0.336**) was observed with the root yield and percentages of disease severity index. The study recognized that the T. harzianum IMI-392433 strain performed well in inhibiting the mycelial growth and reduced the percentages of disease severity index of pathogen as well as increased the plant growth in Ashwagandha.

Hassan Abdel-Rahman Abdel-Rahman,전형규,송근호,강준구,김덕환 한국임상수의학회 2008 한국임상수의학회지 Vol.25 No.6
A 4-year-old male Maltese dog was referred with chief complaint of facial nerve paralysis and hyperthermia. These clinical signs were occurred after tooth extraction. Leukocytosis and swelling of left side of gums were detected. He was medicated with antibiotics for 9 days, however, inability of blinking in left eye, lacrimation and hyperthermia were not improved. The patient was administrated with Oyaksungisan (50 mg/kg, PO, BID) for 14 days and was treated by injection-acupuncture (AP) with bee venom (200 μg/head, two times/week, total three times). The patient was treated by injection-AP with dexamethasone (1 mg/kg, two times/week, total two times). As a result, Left blepharon was slightly blinked at session 4. Blinking of left blepharon became normal after session 5. The present patient was a case with canine facial nerve paralysis which showed favorable therapeutic response by alternative treatment.

Effect of Repeated Freeze-Thaw Cycles on Beef Quality and Safety
Rahman, Mohammad Hafizur,Hossain, Mohammad Mujaffar,Rahman, Syed Mohammad Ehsanur,Hashem, Mohammad Abul,Oh, Deog-Hwan Korean Society for Food Science of Animal Resource 2014 한국축산식품학회지 Vol.34 No.4
The objectives of this study were to know the effect of repeated freeze-thaw cycles of beef on the sensory, physicochemical quality and microbiological assessment. The effects of three successive freeze-thaw cycles on beef forelimb were investigated comparing with unfrozen fresh beef for 75 d by keeping at $-20{\pm}1^{\circ}C$. The freeze-thaw cycles were subjected to three thawing methods and carried out to know the best one. As the number of freeze-thaw cycles increased color and odor declined significantly before cook within the cycles and tenderness, overall acceptability also declined among the cycles after cook by thawing methods. The thawing loss increased and dripping loss decreased significantly (p<0.05). Water holding capacity (WHC) increased (p<0.05) until two cycles and then decreased. Cooking loss increased in cycle 1 and 3, but decreased in cycle 2. pH decreased significantly (p<0.05) among the cycles. Moreover, drip loss, cooking loss and WHC were affected (p<0.05) by thawing methods within the cycles. 2-Thiobarbituric acid (TBARS) value increased (p<0.05) gradually within the cycles and among the cycles by thawing methods. Total viable bacteria, total coliform and total yeast-mould count decreased significantly (p<0.05) within and among the cycles in comparison to the initial count in repeated freeze-thaw cycles. As a result, repeated freeze-thaw cycles affected the sensory, physicochemical and microbiological quality of beef, causing the deterioration of beef quality, but improved the microbiological quality. Although repeated freeze-thaw cycles did not affect much on beef quality and safety but it may be concluded that repeated freeze and thaw should be minimized in terms of beef color for commercial value and WHC and tenderness/juiciness for eating quality.
