Cryptographic System

Security is the most concerned topic in this today’s world of Information and Communication Technology. Single layer security can be breached easily so hybrid cryptographic system has been introduced. Hybrid system can be made by combining two or more algorithms of similar or dissimilar types. Here, combing of Blowfish algorithm along with RSA algorithm is performed. After combination their performance analysis is done based on five parameters namely Throughput, Encryption time, Decryption time, Total Execution time and Plain text size to cipher text size ratio with different key size of Blowfish algorithm ranging from 32 bit-448 bit. Among these 5 different hybrid cryptosystem we found that the Blowfish RSA system with key size 448 bit has better performance than all other bit size.

Information and Communication Technology (ICT) on buses and at major bus terminal in large cities in Indonesia is needed for sustainable transportation. Based on the existing condition of buses and major bus terminals, ICT implementation cannot be completed at one go, but needs to be done in different stages. The aims of this study are identification of existing ICT implementation, to determine the necessity and priority of ICT implementation based on passengers’ needs and to provide stages of ICT implementation on buses and at major bus terminals in Indonesia for the purpose of sustainable transportation. Case studies are carried on Trans-Sarbagita buses and at Mengwi major bus terminal in Denpasar, Bali and on Surabaya-Yogyakarta buses and at Purabaya major bus terminal in Surabaya, Indonesia. Five hundred and sixty-six passengers and the terminal authority are involved in this study. Data collecting method is questionnaire and interview. Important performance analysis is used in analysis. Results indicated that the stages are: 1) maintenance of existing ICT daily operations, i.e. CCTV and online-ticketing, 2) dissemination of existing and future ICT facilities to the society, 3) effort to implement ICT needed by passengers, 4) effort to implement ICT based on passengers’ priority, and 5) implementation of other advanced ICT in the future with financial support and the firm effort of local government, national government and industry, consistently and continuously.

This study delivers the importance-performance analysis of the information and communication technology (ICT) driven solutions among small and family-owned hotels (SFH) in Croatia. The analysis reflects the opinions of owners of 21 SFH, all of which are members of the National Association of Family and Small Hotels (OMH). The findings demonstrated the existence of a significant gap between the perception of the importance of specific innovations and actual hotel performances. In most cases, hotel performances are rated significantly lower than the perceived importance of particular innovation, which indicate that resources should be better and more wisely allocated. In some cases, hotels do not recognise the benefits of ICTs used or are not satisfied with the results. The primary constraint for higher integration of the ICTs within this sample is the lack of financial resources. The study reveals the importance-performance gaps within the perception of technological innovations in the SFHs, elaborates on potential constraints for more substantial reliance on ICTs and discusses the possible implications. Finally, the study provides recommendations for future research.

This paper studies whether and how information and communication technology (ICT) changes self-construal and cultural values in a developing country. Ethiopian children were given laptops in the context of an ICT for development scheme. We compared children who used laptops (n = 69) with a control group without laptops (n = 76) and a second control group of children whose laptop had broken down (n = 24). Results confirmed that after 1 year of laptop usage, the children’s self-concept had become more independent and children endorsed individualist values more strongly. Interestingly, the impact of laptop usage on cultural values was mediated by self-construal (moderated mediation). Importantly, modernization did not “crowd out” traditional culture: ICT usage was not associated with a reduction in traditional expressions (interdependent self-construal, collectivist values). Theoretical and practical implications are discussed.

School Learning

So far, in implementing school strategies, they tend not to utilize Information and Communication Technology (ICT), despite the availability of ICT resources available. Stages of strategic management are needed to generate the vision, mission, objectives, policy, program, budget, and procedures as well as control and evaluation process as an effort to utilize ICT to improve school quality. Based on the interpretation and the results of the study, it is concluded that schools have organized stages in strategic management that enable schools to have a quality profile. The impact of effective utilization of ICTs for schools is the achievement of effective school management, as per the National Education Standards, which is characterized by effective planning, implementation, control, and evaluation of school ICTs.The purpose of this study is to get a general description, describe, and reveal the Strategic Management of Information and Communication Technology Utilization to Improve the Quality of School Learning in Ciledug Al Musaddadiyah Vocational High School and Garut 1 Vocational High School, both on environmental analysis, strategic formulation, implementation and strategic evaluation. The research method used in this research is the case study method, because the problems studied occur in the place and situation of Ciledug Al Musaddadiyah Vocational School and Vocational High School 1 Garut. The use of case study models in this study is based on the consideration that to provide an overview of the strategic management activities of the use of ICTs carried out at vocational high schools with the ultimate goal of being able to improve the quality of school learning. Based on observations in the field of SMK 1 Garut and SMK Al Musaddadiyah Ciledug Garut is one of the public schools and private schools that have these advantages.

Role Of Information

If we want to convert our rural population into knowledge driven, progressive, self sufficient, self reliant, sustainable society, the role of Information and Communication Technologies (ICT’s) cannot be ignored. Timely availability information is considered as most important factor in Indian agriculture. At present ICT is the technology of this millennium. Transferring the developed technology to all end users is time-consuming and tiresome task and is often not completed due to paucity of resources and lack of manpower. In India, agriculture and rural development has gained significantly from ICT due to its widespread extension and adoption. In this era of internet, ICT is committed to provide real, timely accurate authentic information to the farmers and rural peoples.
