Dietary fiber (OF) is now considered as a part of healthful diet because it plays an important role in preventing many of organic diseases. A survey was conducted to evaluate the perceived ro le of DF in healthy diet and its intake level among educated urbanites of Dhaka city. For dietary information, a 24 hours recall method along with a 7 day food frequency questionnaire was used. The findings show that the respondents were aware of OF and were able to name fiber rich foods. They perceived that fruits and vegetables are the rich source of OF. But fiber consumption frequencies showed that majority of them do not take fruits and vegetables everyday. As a result OF intake of the respondents was found 7.87 gjday, far below the recommended level (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) glday or lO g/ 1000 Kcal). Thus the study revealed that though the health benefits of OF was perceived and recognized by our educated population but they do not practice it .

Various factors, including increase in traffic volume and weight, structural aging, and environmental impact, cause damage in structural members. This raises the importance of the maintenance, rehabilitation, and strengthening of reinforced concrete members. External post-tensioning is one of the widely-used strengthening techniques in many countries due to its advantages over other strengthening methods. Although flexural strengthening of existing structural members is a well-established method, shear strengthening of structural members, especially with existing shear cracks, has attained very little attention from researchers. Similarly, external fiber-reinforced polymer (FRP) bonding for shear strengthening of structural members, especially with existing shear cracks, is a relatively new area of research. This paper presents the results of an experimental study on the shear strengthening of reinforced concrete (RC) beams with existing shear cracks by external post-tensioning and external FRP bonding. The test result showed that the combined strengthening technique of external post-tensioning and external FRP bonding can effectively increase the shear capacity of RC beams with existing shear cracks.
