Novel Framework for Hidden Data in the Image Page within Executable File Using Computation between Advanced Encryption Standard and Distortion Techniques
The hurried development of multimedia and internet allows for wide
distribution of digital media data. It becomes much easier to edit, modify and
duplicate digital information. In additional, digital document is also easy to
copy and distribute, therefore it may face many threats. It became necessary to
find an appropriate protection due to the significance, accuracy and
sensitivity of the information. Furthermore, there is no formal method to be
followed to discover a hidden data. In this paper, a new information hiding
framework is presented.The proposed framework aim is implementation of
framework computation between advance encryption standard (AES) and distortion
technique (DT) which embeds information in image page within executable file
(EXE file) to find a secure solution to cover file without change the size of
cover file. The framework includes two main functions; first is the hiding of
the information in the image page of EXE file, through the execution of four
process (specify the cover file, specify the information file, encryption of
the information, and hiding the information) and the second function is the
extraction of the hiding information through three process (specify the stego
file, extract the information, and decryption of the information).Comment: 6 Pages IEEE Format, International Journal of Computer Science and

Growth yield and segregation of several f3 generation of pepper accessions selected from the cross of curly and cayenne peppers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 358-369). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Suboptimal land, in general, refers to condition of the land not prefectly suitable for cultivation, including those containing propagul caused disease infestation. On pepper cultivation, very often occurs disease infestation such as antracnose desease. Crossing curly and cayenne peppers was intended to obtain accessions of curly pepper having fruit position upward such as in cayenne pepper that capable of avoiding several diseases infestation. The F3-seeds were prepared 3 years prior to this research with selection to choose plant genotypes having fruit position upward. Research was done in-cooperation with farmer at Kecamatan Gunung Megang, Muaraenim on December 2022 to May 2023 based on Randomized Block Design with two accessions and three blocks with 10-15 plants per plot. Research indicated that both accessions showed good growth and yield with relatively similar harvesting period and yield potential. Interestingly, we observed several recombinat plants having fruit shape identical to curly peppers with fruit position upward. The plants of CK3(2)xCR3(6) accession, however had more slender fruit shape as compared to CK6(8)xCR6(4) accession. Furthermore observation indicated the presence of segregation of this character. Accession of CK3(2)xCR3(6) showed higher segregation value of 50% than CK6(8)xCR6(4) accession with segregation value of 25%
Factors Influencing Innovation Management in Iraq’s Small- and Medium-sized Enterprises
By adopting technology, enhancing productivity, and fostering economic growth in small and medium-sized enterprises (SMEs), owners and managers can improve their innovation management methods. Owners and managers can optimize their innovation management approaches in small and medium-sized firms (SMEs) by incorporating technology, improving productivity, and promoting economic growth. Despite heightened knowledge of technology, productivity, and economic growth, innovation management has not been adequately examined. This study presents a theoretical framework for evaluating the effects of technology, productivity, and economic growth. A quantitative methodology was utilized, and questionnaires were sent to employees in small and medium-sized enterprises in Erbil, Iraq. This research involved 260 Iraqi workers, and 242 were analysed in Smart PLS. SMEs can address constraints in technology, productivity, and economic growth by implementing these strategies, as indicated by the results. Identifying opportunities for improvement, efficiently allocating resources, and fostering an innovative culture are essential for your company. Technology, productivity, and economic growth have a direct and considerable influence on innovation management. The technological aspect is the most crucial feature in predicting innovation management
Эффективность in vitro инактивации бактерий Bacillus subtilis и Escherichia coli в стерилизаторах с использованием облучения в фиолетовой области
Bacteria are inactivated using a technique called photodynamic inactivation, which combines light with a photosensitizer with the right spectrum. The objective of this study is to ascertain the eciency of purple LEDs for photoinactivating Bacillus subtilis and Escherichia coli bacteria as well as the ideal purple LED exposure energy density. This study technique involves exposing bacteria to purple LED radiation. Two elements of variation are used during irradiation. The first variation is the illumination variation at distances of 3 cm, 6 cm, 9 cm, and 12 cm. The second variation involves changing the amount of radiation for 30, 60, 90, and 120 minutes. The Total Plate Count (TPC) method was used to count the number of colonies. Statistical tests were utilized in data analysis, namely the One Way Anova test (analysis of variance). The results of this study indicated that 395 nm purple LED irradiation caused a decrease in Log CFU/mL of Bacillus subtilis and Escherichia coli bacteria. Inactivation of Bacillus subtilis bacteria showed a higher mortality percentage than Escherichia coli bacteria. Changes in other irradiation distances also showed a higher percentage of death for Bacillus subtilis bacteria than Escherichia coli bacteria. The highest percentage of death was 98.5% for Bacillus subtilis bacteria and 94.3% for Escherichia coli bacteria at position C with an irradiation distance of 3 cm and an energy density of 524 J/cm2 with an LED exposure time of 120 minutes. This shows that the percentage of death of bacteria Bacillus subtilis and Escherichia coli increased with increasing doses of LED energy with the greatest percentage of death in Gram-positive bacteria Bacillus subtilis.Инактивация бактерий может быть выполнена с использованием метода, называемого фотодинамической инактивацией, в основе которого лежит активация фотосенсибилизатора светом определенного спектра. Целью данного исследования является определение эффективности светодиодов с излучением в фиолетовой области спектра для фотоинактивации бактерий Bacillus subtilis и Escherichia coli, а также определение оптимальной плотности энергии воздействия. При облучении были использованы два изменяемых параметра. Первый параметр – это расстояние от источника облучения до облучаемой поверхности (3 см, 6 см, 9 см и 12 см). Второй параметр – время облучения (30, 60, 90 и 120 мин). Для подсчета количества колоний использовали метод общего подсчета чашек (Total Plate Count). При анализе данных использовали статистические тесты, а именно тест One Way Anova (дисперсионный анализ). Результаты этого исследования показали, что светодиодное излучение в фиолетовой области спектра с длиной волны 395 нм вызывало снижение log КОЕ/мл бактерий Bacillus subtilis и Escherichia coli. Воздействие на бактерии Bacillus subtilis показало более высокий процент смертности, чем для бактерий Escherichia coli. Лучшие результаты были получены при расстоянии до источника облучения 3 см, плотности энергии 524 Дж/см2, и времени воздействия светодиода 120 мин. В этом режиме было инактивировано 98,5% бактерий Bacillus subtilis и 94,3% бактерий Escherichia coli
Single nucleotide polymorphisms from Theobroma cacao expressed sequence tags associated with witches' broom disease in cacao
In order to increase the efficiency of cacao tree resistance to witches¿ broom disease, which is caused by Moniliophthora perniciosa (Tricholomataceae), we looked for molecular markers that could help in the selection of resistant cacao genotypes. Among the different markers useful for developing marker-assisted selection, single nucleotide polymorphisms (SNPs) constitute the most common type of sequence difference between alleles and can be easily detected by in silico analysis from expressed sequence tag libraries. We report the first detection and analysis of SNPs from cacao-M. perniciosa interaction expressed sequence tags, using bioinformatics. Selection based on analysis of these SNPs should be useful for developing cacao varieties resistant to this devastating disease. (Résumé d'auteur
