The objective of this article was to describe 1) the validation of 2 similar but not identical food security modules used to collect data from 2 vulnerable populations, southern Lebanon residents (n = 815) and Palestinian refugees in Lebanon (n = 2501), and 2) the development and validation of an Arab Family Food Security Scale (AFFSS). The surveys used a cluster-randomized sampling design. The...

BACKGROUND Many developing countries increasingly recognize and acknowledge family planning as a critical part of socio-economic development. However, with few health dollars to go around, countries tend to provide essential drugs for curative care, rather than for family planning products. Donors have historically provided free contraceptives for family planning services. Whether products are ...

background: considering the effect of socioeconomic factors on the appearance of chronic diseases, and also the importance of this issue for policy makers of health care services, we tried to assess the role socioeconomic factors have in diabetes complications. this survey may have some benefits in prevention and control of diabetes.   methods: this cross-sectional study was conducted on 384 di...

Over the recent months it has become clear that the current generation of cryptographic hashing algorithms are insufficient to meet future needs. The ASH family of algorithms provides modifications to the existing SHA-2 family. These modifications are designed with two main goals: 1) Providing increased collision resistance. 2) Increasing mitigation of security risks post-collision. The unique ...

Introduction: Suicide resulting of psychological and social disturbances. Family, as an intermediate institute, has a bilateral role; on one hand provides a protective factor for health. Meanwhile, family malfunctions work as a risk factor in suicide. This research is performed to study family risk factors and functioning among suicide attempted. ...

A “strong” cryptographic hash function suitable for practical applications should simultaneously satisfy many security properties, like pseudo-randomness, collision resistance and unforgeability. This paper shows how to combine two hash function families each satisfying different security property into one hash function family, which satisfies both properties. In particular, given two hash func...
