Communication through the internet is one of the dominant methods of exchanging information. TCP and UDP are the transport layer protocols responsible for transit of nearly all Internet communications. Due to the growth of real-time audio and video applications, UDP is being used more frequently as a transport protocol, but unlike TCP, UDP has no mechanism for congestion control leading to wasted bandwidth and poor performance, so the DCCP protocol has appeared as a replacement for UDP. In this article, the author performs some simulations using NS2 for Drop Tail and RED queuing models to evaluate the performance of TCP, UDP, DCCP CCID2, and DCCP CCID3 protocols in congested wired networks. The performance metrics used are throughput, end to end delay, number of sent and lost packets. The obtained results show that the DCCP CCID2 performs the best throughput with the minimum of delay as compared to UDP, TCP, and DCCP CCID3.

The issue of disability is one of the most important social issues in all human societies. Disability has become particularly important as a result of the statistics done by many international organizations and bodies. These statistics have strikingly confirmed high rates of disabilities. It is worth noting that these high rates of disability are viewed as a real waste of human resources in the human society, where human resources are one of the most important elements of its development. Every child who is born in a family and diagnosed as a disabled child with one of the motor, mental, sensory or social disabilities makes changes in the social environment where he or she lives. The change starts in concepts and determinants of family members' understanding of the new situation.

Building maintenance is gaining increased attention in the various fields of scientific research, Building information modelling (BIM) is used in the maintenance management and has helped facility management to handle a large volume of maintenance information, including drawings, specifications, lists and reports. BIM proved its effectiveness as a repository for various types of data in buildings maintenance and a tool to support decision making in maintenance. stepping the best decision at the facility is not only based on quantitative data but also on the knowledge and experience acquired by the company and the employees. this experience may be lost forever due to resignation and retirement if they are not documented. In this research work the authors provide a methodology for obtaining knowledge while performing maintenance of public buildings using BIM and DYNAMO applications, where parametric models provide us with a high-central frame for storing information and by adopting of visual programming, which provides great capabilities for processing, extraction, classification and the export of data from the BIM model to organize the knowledge management process extensively. This serves to facilitate decision-making through the BIM dependent knowledge base which helps to obtain and re-use of generated knowledge.

Volunteering is one of the various social activities that human societies have known and practiced since their inception. It is not the outcome of the last decades of the life of these societies, but it was present in almost every human civilization in its various forms and methods. Voluntary work is of great importance as far as individuals and societies are concerned. It is a symbol of solidarity among the members of the community and all its institutions. It positively affects people's lives as well as the community at large. It symbolizes the meanings of good, giving, and help. Accordingly, volunteering has become a cornerstone in building society and social cohesion among its members. In this regard, voluntary work is of great importance. It necessitates the need to spread this culture in the society and to promote and develop volunteerism among young people using all available and possible methods.

Blockchain technology is an electronic ledger of digital records that is distributed over a network of computers rather than located on single or multiple servers. As the technology is by itself transparent and secure even without a trusted third party involvement, many applications are being developed as a means of eliminating corruption around the world. This article examines how the blockchain technology could be used to curb corruption and take integrity to higher standards at a firm level, within-country level and cross-country level. Possible risks and challenges related to the technology were identified and found that without considering the data governance and security issues, the blockchain technology may not always lead to a socio-economic benefit.

The learning process has evolved with time. The primary change that technologies have brought into the learning process is more structure and activity based. It has become a necessity and a mandate as well to keep a track of details of educational activities so that it can be referred back to at any point in time. Moreover, it requires a secure protocol which is trustworthy, transparent, less vulnerable and requires near zero involvement of mediators. Blockchain technology has a tremendous potential to disrupt the education sector. Its implementation will help to maintain time-stamped record keeping that can be validated for all types of activities involved in the professional education system. This article proposes a blockchain-based model for professional education systems. The model not only ensures digital identity, verifiable records, but also motivates learning process by rewarding B-coins for learning activities. It inherits the security, robustness of underlying blockchain technology and eliminates the need for verification by an intermediate agency.
