Role of Psychosocial Support in Women Empowerment

Rabia FAYYAZ 이화여자대학교 아시아여성학센터 2012 이화여자대학교 아시아여성학센터 학술대회자료집 Vol.2012 No.7

Comprehensive Health and Education Forum (CHEF) International is working in the Charsadda District of Khyber Pakhtunkhwa Province of Pakistan, which has a population of over a million people. Culturally, Charsadda is one of the most conservative areas of KPK where men are considered dominant, and women have been victims of a wide range of discriminations, resulting in the deterioration of their mental health. Most of the people living in Charsadda belong to a poor socio-economic class. The area is recently affected by both conflict as well as natural disasters which makes the need for psychosocial support in women empowerment even more critical. Women empowerment educates and empowers women with the skills and confidence necessary to develop a healthy lifestyle, but it is not possible until she is provided with psychological / psychosocial empowerment. Thus the first step towards empowerment is psychologically empowering women. CHEF International is promoting and contributing towards comprehensive development especially for persons with disabilities. Mental Health is one of the major components where CHEF International is promoting and empowering individuals with a special focus on women in its field based hospital District Medical and Rehabilitation Complex. The team of Psychologists provides psychosocial support to women by initially identifying the needy, providing assessment and psychosocial support in order to rehabilitate them back into their respective communities. The rehabilitation process includes regular follow-ups inside the community by paying home visits, free medical camps on need basis, provision of awareness about mental health, and making referrals to the concerned departments. After complete psychosocial support, women also feel empowered in the other domains of life as well. With regular provision of awareness and education on mental health people have gradually started understanding the importance of mental health on their lives, leading to empowerment and behavioral change in a very cost efficient manner. With the passage of time and provision of high quality services the community has gained a lot of confidence in the Mental Health Unit of DMRC, and as a result the number of visitors has increased manifolds. CHEF International is planning to strengthen and extend the program on mental health in future so as to empower and rehabilitate more and more women from the community.

Rabia, Benferhat,Tahar, Hassaine Daouadji,Abderezak, Rabahi Techno-Press 2020 Coupled systems mechanics Vol.9 No.6

The effect of porosity on the thermo-mechanical behavior of simply supported functionally graded plate reposed on the Winkler-Pasternak foundation is investigated analytically in the present paper using new refined hyperbolic shear deformation plate theory. Both even and uneven distribution of porosity are taken into account and the effective properties of FG plates with porosity are defined by theoretical formula with an additional term of porosity. The present formulation is based on a refined higher order shear deformation theory, which is based on four variables and it still accounts for parabolic distribution of the transverse shearing strains and stresses through the thickness of the FG plate and takes into account the various distribution shape of porosity. The elastic foundation is described by the Winkler-Pasternak model. Anew modified power-law formulation is used to describe the material properties of FGM plates in the thickness direction. The closed form solutions are obtained by using Navier technique. The present results are verified in comparison with the published ones in the literature. The results show that the dimensionless and stresses are affected by the porosity volume fraction, constituent volume fraction, and thermal load.

Analysis and sizing of RC beams reinforced by external bonding of imperfect functionally graded plate

Rabia, Benferhat,Daouadji, Tahar Hassaine,Abderezak, Rabahi Techno-Press 2021 Advances in materials research Vol.10 No.2

An analytical method based on the compatibility of deformations and equilibrium of forces is investigated to predict the reinforcement plate area in concrete beams strengthened with Functionally Graded (FG) plates bonded to the tension face of the beams. The models are given for beams having rectangular and T-cross-sections. The effect of porosity that can happen inside FGM materials during their manufacture is also shown. New rules of the mixture that take into account different distribution rates of porosity in FG plates have been developed in this study. A parametric study is conducted to investigate the effect of several parameters such as the ultimate moment, plate stiffness, the distribution rate of the porosity, and compressive strength of the concrete. The results obtained show a significant gain in the reinforcement plate area of the RC beam strengthened with an FG plate relative to another reinforced with FRP plate, which makes it possible to reduce the interfacial stresses and prevents detachment of the reinforcing plate.

Predictions of the maximum plate end stresses of imperfect FRP strengthened RC beams: study and analysis

Rabia, Benferhat,Daouadji, Tahar Hassaine,Abderezak, Rabahi Techno-Press 2020 Advances in materials research Vol.9 No.4

A theoretical method to predict the interfacial stresses in the adhesive layer of reinforced concrete beams strengthened with porous FRP plate is presented in this paper. The effect due to porosity is incorporated utilizing a new modified rule of mixture covering the porosity phases. The adherend shear deformations have been included in the present theoretical analyses by assuming a linear shear stress through the thickness of the adherends. Remarkable effect of the porosity has been noted in the results. Indeed, the resulting interfacial stresses concentrations are considerably smaller than those obtained by other models which neglect the porosity effect. It was found that the interfacial stresses are highly concentrated at the end of the FRP plate, the minimization of the latter can be achieved by using porous FRP plate in particular at the end. It is also shown that the interfacial stresses of the RC beam increase with volume fraction of fibers, but decrease with the thickness of the adhesive layer.

Structural, dielectric and magnetic properties of cobalt based spinel ferrites

Rabia Qindeel,Norah H. Alonizan 한국물리학회 2018 Current Applied Physics Vol.18 No.5

CoYbxFe2-xO4 (x=0.00, 0.025, 0.05, 0.075, 0.10) spinel ferrites were synthesized by co-precipitation technique. Structural, dielectric and magnetic properties were measured. X-ray diffraction analysis showed that all the prepared spinel ferrites possessed cubic spinel structure. Dielectric constant, AC conductivity and dielectric loss decreased with the addition of rare earth ions. The impedance analysis explained the role of grains and grain boundaries with in prepared samples. Cole-Cole plots helped to measure the values of grains and grain boundary's resistance. The magnetic properties proved the soft nature of these ferrites. Saturation magnetization and remanence decreased while coercivity was enhanced with the addition of ytterbium concentration. All these parameters suggested that these prepared samples might be suitable for high frequency applications.

In this paper, a closed-form rigorous solution for interfacial shear stress in simply supported beams strengthened with bonded prestressed E-FGM plates and subjected to an arbitrarily positioned single point load, or two symmetric point loads is developed using linear elastic theory. This improved solution is intended for application to beams made of all kinds of materials bonded with a thin plate, while all existing solutions have been developed focusing on the strengthening of reinforced concrete beams, which allowed the omission of certain terms. The theoretical predictions are compared with other existing solutions. Finally, numerical results from the present analysis are presented to study the effects of various parameters of the beams on the distributions of the interfacial shear stresses. The results of this study indicated that the E-FGM plate strengthening systems are effective in enhancing flexural behavior of the strengthened RC beams.

Emergency Signal Detection based on Arm Gesture by Motion Vector Tracking in Face Area

Rabia Fayyaz,박대준,이은주 한국정보전자통신기술학회 2019 한국정보전자통신기술학회논문지 Vol.12 No.1

This paper presents a method for detection of an emergency signal expressed by arm gestures based on motion segmentation and face area detection in the surveillance system. The important indicators of emergency can be arm gestures and voice. We define an emergency signal as the ‘Help Me’ arm gestures in a rectangle around the face. The ‘Help Me’ arm gestures are detected by tracking changes in the direction of the horizontal motion vectors of left and right arms. The experimental results show that the proposed method successfully detects ‘Help Me’ emergency signal for a single person and distinguishes it from other similar arm gestures such as hand waving for ‘Bye’ and stretching. The proposed method can be used effectively in situations where people can’t speak, and there is a language or voice disability.
