Egypt has been known as the light house of science and innovation not only in the Middle East but to the world across ages. Recently, there have been many ups and downs that positioned Egypt in a lower rank that it actually deserves according to its long history. This review entitles the current condition of science, technology and innovation in Egypt and the consequent setting up of best practices of science and technology parks (STPs) experiences. Egypt's science, technology and innovation (STI) system is highly centralized and dominated by the public sector, with R&D happening mostly in state-run universities and research centers supervised by the Ministry of Higher Education and Ministry of Scientific Research. R&D indicators state that Egypt ranking is 40th worldwide for the published articles (around 10,000 papers in 2011), while the numbers of issued patents (350 local and 50 international in 2011) is still far beyond expected. STPs in Egypt are addressed in this review by three examples; smart village in Cairo, Investment zone in Borg El-Arab City and Technology Valley in Ismailia. The three models are discussed in details and a suggested road map for developing more STPs is estimated.

The synthesis of osme quinoxaline derivatives containing indoline-2, 3-dione or thiazolidlinone residue is described. The synthesized derivatives were sureened in vitro for their growth inhibitory activity against six species of bacteria, viz. Staphylococcus aureus, Streptococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Serratia marcescens and Mycobacterium semegmatils. Most of the compounds exhibited antimicrobial activity especially those having indoline-2, 3-dione moiety.

Five aromatic compounds, of which two are new glucosides, and six flavonols were isolated and identified for the first time from the flower heads and aerial shoots of Helichrysum conglobatum (Asteraceae). Their structures were established on the basis of chemical and spectroscopic methods including UV, MS, 1D- and 2D-NMR. Some fractions and isolates were screened for anti-microbial activities. This is the first report of the isolation of the chemical constituents of this species.

Manual elections processes in Egypt have several negative effects; that mainly leads to political corruption due to the lack of transparency. These issues negatively influence citizen's participation in the political life; while electronic voting systems aim to increase efficiency, transparency, and reduce the cost comparing to the manual voting. The main research objectives are, finding the successful factors that positively affects E-voting implementation in Egypt, in addition of finding out the reasons that keep Egyptian government far from applying E-voting, and to come up with the road map that Egyptian government has to take into consideration to successfully implement E-voting systems. The findings of the study suggest that there are seven independent variables affecting e-voting implementation which are; leadership, government willingness, legal framework, technical quality, awareness, citizen's trust in government and IT literacy. Technology-Organization-Environment (TOE) theory was used to provide an analytical framework for the study. A quantitative approach (i.e., survey questionnaire) strategy was used to collect data. A random sampling method was used to select the participants for the survey, whom are targeted voters in Egypt and have access to the internet, since the questionnaire was distributed online and the data is analyzed using regression analysis. Practical implications of this study will lead for more citizen participation in the political life due to the transparency that E-voting system will create, in addition to reduce the political corruption.

A series of Schiff's benzimidazole bases, thiosemicarbazides were synthesized, azole ring systems as 1,3,4-triazole, 1,3,4-oxadiazole were prepared. 1-Methylbenzimidazole incorporated to substituted dithio-carbamate, thiophenol, diethylamine via acetamido group were synthesized. A series of pyrimidinobenzimidazoles, triazinobenz-imidazoles, and 2-(acetonylamino)-1-methyl-benzimidazole were prepared. The antimicrobial and molluscicidal activities of some newly prepared compounds were carried out.

This study aims to isolate and identify the causal pathogen of tomato bacterial wilt in Egypt. In 2008, tomato plants showing typical symptoms of bacterial wilt disease with no foliar yellowing were observed in Minia, Assiut and Sohag governorates, Egypt. When cut stems of symptomatic plants were submerged in water, whitish ooze was evident and longitudinal sections showed a brown discoloration in the vascular tissues. Bacteria were isolated on triphenyl tetrazolium chloride medium and fifteen isolates shown typical morphological and cultural characteristics were confirmed as Ralstonia solanacearum biovar 2 race 1. Pathogenicity tests showed that all isolates proved to be pathogenic to tomato plants, varied from 52 to 97% wilting. This is the first report of R. solanacearum biovar 2 race 1 causing bacterial wilt in tomato crop in Egypt.

본 연구는 이집트의 농업발달을 사회 및 정치적인 변화와 관련하여 고찰하고, 오늘날 농업의 공간적 분포를 주요 작물 및 지역별로 설명하고자 하였다. 또한 이 지역에서 농업용 토지개발의 과정과 영농의 주체를 살펴보았다. 이집트 농업은 국제무역 관계에서 발전하였고, 특히 목화 및 사탕수수와 같은 작물은 국가의 전략적 작물로서 보호 및 관리되었다. 토지소유와 같은 문제는 주요 시대별 정치환경에 의해서 뚜렷이 대조가 되지만, 전략적 작물에 대한 국가의 관리는 어느 정도의 차이는 있으나 비교적 일관되게 유지되었다. 1990년대 이후 국가 경제의 자유화 정책과 맞물려 농업에서도 그 영향이 반영되어 작물의 경작과 토지 개간 사업의 개방에 뚜렷이 나타나고 있다. 농업의 공간적 및 영농의 성격은 델타, 중 이집트 및 상 이집트(Middle and Upper Egypt), 사막지역으로 나누어 파악하였다. 아울러 1950년대 이후 이집트의 경제 및 사회문제를 해결하기 위한 국가적 사업인 토지 개간의 발전과 개간된 토지에 대한 영농 주체의 성격을 고찰하였다.
