Background and objectives: Maternal as well as infant mortality is high in Bangladesh. Utilization of post natal care (PNC) services is important to reduce maternal and infant mortality. Considering this matter, this study attempted to find out the level of PNC utilization by women living in slum areas of Dhaka city as well as to identify the factors associated with the utilization of PNC services. Methods: This study was conducted in Khilgaon and Rampura slums of Dhaka city. In each slum, women aged between 15-49 years who had given birth to at least one child were enrolled in the study by random sampling technique. Participants were interviewed with a semi-structured questionnaire which included information on socio-economic, demographic, cultural status as well as information on PNC service utilization. Results: Out of total 360 enrolled women in both slums, 58.6% utilized PNC services. The rate of utilization of PNC services was 55% and 62.2% in Khilgaon and Rampura slum respectively. Compared to 40-49 years age group, significantly (p<0.01) higher percentage of women aged <20, 20-29 and 30-39 years utilized PNC services (69.6%, 67.0% and 56.4% respectively). The significant associates of receiver of PNC were respondent’s education, number of antenatal care (ANC) received, level of tetanus vaccination, place of delivery, distance between home and clinic, mass media exposure, male participation and autonomy. Conclusion: Local socioeconomic and cultural aspects should be considered while planning intervention program to improve the utilization of PNC service. Ibrahim Med. Coll. J. 2019; 13(2): 53-58

This paper presents vibration control of a building model under earthquake loads. A magnetorheological (MR) damper is placed in the building between the first floor and ground for seismic response reduction. A new control algorithm to command the MR damper is proposed. The approach is inspired by a quasi-bang-bang controller; however, the proposed technique gives weights to control commands in a fashion that is similar to a fuzzy logic controller. Several control algorithms including decentralized bang-bang controller, Lyapunov controller, modulated homogeneous friction controller, maximum energy dissipation controller, and clipped-optimal controller are used for comparison. The new controller achieved the best reduction in maximum interstory drifts and maximum absolute accelerations over all the control algorithms presented. This reveals that the proposed controller with the MR damper is promising and may provide the best protection to the building and its contents.

The present study was an attempt to determine the factors affecting the livelihood of the socioeconomic improvement of migrants and to analyze the causes of rural-urban migration in slum areas. Slum areas have no available formal education facilities and slum people were found to be engaged in rickshaw pulling, day labourer, petty business, small job services etc. Analysis showed that migration and taking in micro credit were beneficial for the slum dwellers. Receiving and utilizing micro credit income level, consumption, expenditure and socio-economic status of the slum dwellers improved to some extent. Due to participation of slum dwellers in NGOs, their economic, social and decision making improved substantially. Credit disbursement through NGOs with integrated approach could bring positive changes in the life of poor slum women as well as their community. Findings showed that Fifty six per cent people migrated to Dhaka city for economic reason. Factors of migration had a significant contribution of rural urban migration and also significant livelihood improvement has taken place due to micro credit. At the individual level, the women were benefited in terms of mobility and skill, self confidence, widening of interests, access to financial services, build own savings, competence in public affairs and status at home and in the community that lead a better awareness for enhancing women's empowerment. However, there is a need for proper training for sustainable result in the long run. Keywords: Migration; Livelihood; Micro credit DOI: 10.3329/jbau.v7i2.4750 J. Bangladesh Agril.

Abstract On February 25 (UTC), 2018, the project, a combine of wellpads, gathering lines, transport pipelines and its facilities, sustained a Mw7.5 earthquake, and ca. 300 aftershocks, epicentered directly under the key facilities. Around 150 km of high-pressure gas and condensate pipelines were affected. A number of design and construction decisions protected the pipelines, and prevented serious damage. However, the earthquake disturbed several sections of the pipeline Right-of-Way (ROW), which subsequently required intervention and stabilization. The challenges associated with re-occupying the remotely-situated, mountainous and disturbed ROW, and safely installing stabilization structures, led to the development of a new pipeline stabilization concept: the contiguous Micropile-Wall system. The concept, leveraging tools and techniques from the tunneling industry, and practices from the Alpine region, consists of 139.7 mm micro piles, installed in 3 m joints, in rows along either side of the pipeline. Once installed, opposing rows of these micropiles are attached to each other at ground level with steel tendons. This new concept can be installed using light equipment with minimal vibration and ground disturbance. It is designed to sustain significant earthquake loads, does not retain groundwater, and is resistant to corrosion and third-party damage. This concept was developed and selected in order to repair parts of the damaged ROW and ensure pipe integrity. Future deterioration of the adjacent slopes was taken into account, but slope stabilization for several dozens of landslides was not looked into, as this would have been too large an effort considering the remoteness of the terrain, climatic conditions, safety considerations and other constraints.
