Emerging research concerns about the authenticated cloud service with high performance of security and assuring trust for distributed clients in a smart city. Cloud services are deployed by the third-party or web-based service providers. Thus, security and trust would be considered for every layer of cloud architecture. The principle objective of cloud service providers is to deliver better services with assurance of trust about clients' information. Cloud's users recurrently face different security challenges about the use of sharable resources. It is really difficult for Cloud Service Provider for adapting varieties of security policies to sustain their enterprises' goodwill. To make an optimistic decision that would be better suitable to provide a trusted cloud service for users' in smart city. Statistical method known as Multivariate Normal Distribution is used to select different attributes of different security entities for developing the proposed model. Finally, fuzzy multi objective decision making and Bio-Inspired Bat algorithm are applied to achieve the objective.

Hepatit B virüsü (HBV), Bangladeş'te morbidite ve mortalitenin önemli nedenlerinden biridir. Genel populasyonda yeterli düzeyde bilgi ve farkındalık, bu enfeksiyonun önlenmesinde ve kontrolünde şarttır. Gereç ve Yöntemler: Başvuran hastalar arasında kesitsel bir olgu kontrol çalışması yürütüldü. Veriler, kendi kendine yönetilen yapılandırılmış bir anket kullanılarak toplandı ve SPSS kullanılarak analiz edildi. Bulgular: Bu çalışmaya katılan 240 hastanın 120'si hepatit B yüzey antijeni (HBsAg)-pozitif iken, diğer 120'si negatif idi. Çalışma, HBsAg'nin negatif olduğu meslektaşlarıyla kıyaslandığında, okuma yazma bilmeyen hastalar ile çiftçi, perakendeci ve gündelik işçi grupları arasında HBsAg pozitifliğinin daha yüksek olduğunu göstermiştir. Anlamlı bir kısmın, hepatit B enfeksiyonunun sonuçları hakkında hiçbir bilgisi yoktu. Her iki gruptaki hastaların üçte ikisinden fazlası, bulaşma şeklinden ve hepatit B aşılarından habersizdi. Katılımcıların yaklaşık üçte biri (%30) hepatit A'yı hepatit B ile karıştırmıştır. Sonuç: Çalışmaya dahil edilen hastaların çoğu HBV enfeksiyonunun nedeni hakkında fikir sahibi idi. Bununla birlikte, bulaşma şekli ve sonuçları hakkında ciddi yanlış anlamaları mevcuttu. Dolayısıyla, hepatit B hakkındaki farkındalığı artırmak için spesifik olarak hedeflenen plan formüle edilmeli ve uygulanmalıdır. Anahtar Kelimeler: Bilgi, farkındalık, kabul edilen hastalar, hastane, Bangladeş ÖZ Objectives: Hepatitis B virus (HBV) infection is a major cause of morbidity and mortality in Bangladesh. An adequate level of knowledge and awareness among the general population is essential in prevention and control of the infection. Materials and Methods: A cross-sectional case-control study was conducted among patients who were admitted to our hospital. Data was collected using a self-administered structured questionnaire and analyzed by using SPSS. Results: Out of 240 respondents included in this study, 120 were hepatitis B surface antigen (HBsAg)-positive and 120, HBsAg-negative. The study shows that as compared to HBsAg-negative counterparts, HBsAg positivity rate was found to be higher in illiterate patients and among farmers, retailers, and day-laborer groups. A significant fraction did not have any knowledge about consequences of hepatitis B infection. More than two-thirds of the patients from both groups were unaware of transmission mode and vaccination of hepatitis B. About one-third (30%) of the respondents mixed up hepatitis A with hepatitis B. Conclusion: The majority of the patients included in this study had an idea about the cause of HBV infection. However, they had substantial misunderstandings about its mode of transmission and consequences. Hence, a specifically-targeted plan has to be formulated and implemented to increase the awareness about hepatitis B.

BACKGROUND Hepatitis B virus infection is a major public health problem worldwide. Pregnant women are a vulnerable group with a risk of transmitting the virus to the newborn if the mother is infected resulting in the risk of developing chronic infection and carrier state in the infants in later life. Effective strategies for reducing the incidence of chronic infection include screening of antenatal mothers combined with administration of HBV vaccination and immunoglobulin, immediately after birth to all children born to Hepatitis B surface antigen (HBsAg) positive mothers. HBsAg is the first serological marker of active HBV infection. Thus, screening of pregnant mothers for HBsAg would help in identifying mothers at risk of transmitting the infection to infants.
