Customer driven quality improvement of a specific product through ahp and entropy based qfd: a case study

Abstract: Understanding the voice of the customers (VOCs) and properly incorporating their preferences and perceptions into the conceptual design process is the core step of customer-driven product development. To improve customer satisfaction and market profitability, the design team should have a customer-driven quality management and product development system. Quality function deployment (QFD) is an important customer-driven quality management tool that helps identify customer requirements and translate them into proper technical measures. This paper focuses on the application of the AHP and an entropy-based QFD approach on a manufacturing company to improve the quality of its product (blender) and determine the priorities for further improvement. The paper shows how customer requirements can be identified and applied to prioritize the design requirements for improving the quality of a blender. The Analytic Hierarchy Process (AHP) is integrated to determine the final importance of the weights of the customer needs, and entropy is used to determine the set of priority ratings. This integrated framework can help achieve an effective evaluation of the final design solution for product development by overcoming the pitfalls of the traditional QFD approach. An application in a Bangladeshi company that produces blenders is presented to illustrate the performance of the proposed approach.

In-vivo evaluation of the anti-diarrheal effect of Lactococcus lactis subspecies lactis and Lactococcus piscium isolated from yogurt.

Abstract: Lactobacillus and Lactococcus species found in the yogurt of different sources are most widely assayed and used all over the world as a probiotic agent. This study aimed to isolate and identify novel probiotic agents with therapeutic value against diarrhea. Initially, the probiotic properties of the isolated lactic acid bacteria from the yogurt samples of the Chittagong division, Bangladesh, were evaluated. All probiotic candidates inhibited the growth of selected pathogens, including Escheriachia coli, Serratia sp. Salmonella paratyphi, Streptococcus Group-B, Staphylococcus aureus, Haemophillus influenzae, Bacillus subtillis, and Klebsiella pneumoniae. Lactococcus lactis subsp lactis were found most useful in inhibiting all the selected pathogens. When the probiotics were applied against castor oil-induced diarrhea in the rat model, Lactococcus lactis subspecies lactis and Lactococcus piscium were found significantly effective relative to the controls indicating their potentiality as an alternative therapeutic against diarrhea. HighlightsO_LILactococcus lactis subspecies lactis and Lactococcus piscium has shown potentiality to be a therapeutic agent against castor-oil induced diarrhea in an animal model.

Translating Ecology and Material Culture: Understanding Strategies and Shift in The Ballad of Ayesha

Abstract: The current study exposes the translation strategy of ecology and material culture in The Ballad of Ayesha (2018) and the resulting translation shift. This novel is Inam Ahmed’s English translation of the Bengali novel Ayeshamangal (2010) by Anisul Hoque. Ayeshamangal is a Bengali novel written in a fully Bengali context and it is quite difficult for the translator to translate the issues of ecology and material culture by keeping the flavor of the original text intact. The current paper attempts to evaluate whether the translator is successful or not in conveying the sense of the original text to the translated one. This research also investigates the translator’s attitude to equivalence in the TT as well as the problems and dilemma he faces in dealing with various cultural aspects of the novel as we know that English and Bengali languages have different structures. Peter Newmark’s concept of cultural categories in translation is a key to the discussions attempted in this study. The paper foregrounds the translating issues of ecology and material culture in the TT, attempts to investigate the procedures and strategies used by the translator, and probes the possible translation shift.

Increasing incidence of hepatitis A in Bangladesh

Abstract: Hepatitis A (HAV) infection is caused by the hepatitis A virus which is transmitted through the fecal-oral route. Life long protective antibodies are present after infection. The number of cases of adult hepatitis A has progressively been increasing during the last several decades in Bangladesh. In addition, the pattern of age-specific seroprevalence of anti-HAV has changed with economic growth. The prevalence of anti-HAV in 20-40 year age range has declined rapidly during the last 3 decades. As a result, this age groups has a high risk for HAV infection and clinically overt hepatitis A is increasing in adolescents and adult. The aim of the present study were to assess whether the proportion of adults with acute HAV infection has been increasing over the years and analyze the seroprevalence of immunoglobulin M(IgM) anti- HAV antibodies in young adults below the age of 20 years as well as in cases of chronic liver disease. Sera collected from 530 patients with acute and chronic liver disease attends the Somorita Hospital Ltd. during the previous 2 years and 6 months (Jan. 2008- Jun. 2010) were tested for various serological markers of acute and chronic hepatitis. In addition, 530 normal healthy attendants of the patients above the age of 20 years were tested for IgM anti-HAV as controls. Of 530 patients with acute hepatitis (13.42%) were positive for immunoglobulin M. The patients who were IgM anti-HAV negative were found to be hepatitis B (106 patients), hepatitis C, (10 patients), hepatitis E (150 patients) and unclassified (273 patients). Although the frequency of HAV infection among young adult (< 20 age) had increased (33.33% to 42.35%) in the 2 years and 6 months period, the frequency of HAV infection among adults had also increased (15.38% to 28.13%) during the same period. This study should be helpful for the identification of high risk population for vaccination of hepatitis A. DOI: http://dx.doi.org/10.3329/bjsir.v47i3.13065 Bangladesh J. Sci. Ind.

Responses of barley seedlings to arsenic toxicity under various pH levels in the rooting medium

Abstract: The water culture experiment was conducted to observe the effect of pH on the physiology and mineralogy of arsenic (As) toxic barley plants. The pH levels were 4.5, 5.5, 6.5 and 7.5 in presence and or in absence of 13.4 µM As. The experiments were done with 3 replications. Arsenic was used as sodium meta arsenite (NaAsO2). In presence of As, the lowest growth of the plants was at pH 4.5, the 2nd lowest growth was at pH 7.5 and the highest growth was at pH 6.5, indicating that As was more toxic at pH 4.5 and 7.5 as compared to pH 6.5. Arsenic concentrations were higher in the shoots and roots of pH 4.5 and 5.5 levels as compared to pH 6.5 level, suggesting that the bioavailability of As was much higher in acidic solution. Arsenic accumulation was the highest in the pH 5.5. The result suggested that, the bioavailability of As was less in around neutral pH condition. The findings also suggested that pH in the growth media might control the bioavailability and phytotoxicity of As. Concentrations of phosphorus (P), potassium (K), Calcium (Ca), magnesium (Mg), iron (Fe) and zinc (Zn) were not affected at all in the As treated shoots, but the accumulations of those elements increased in 6.5 pH treated shoots, indicating that the As-toxicity was lower at pH 6.5. The result suggested that the pH in the growth medium should be maintained at around the neutral condition to reduce As-toxicity for sustainable graminaceous crop production.
