The volatile oils obtained from the leaves of four pecan cultivars growing in Egypt were evaluated for their chemical composition and antimicrobial activity. The selected cultivars (cv.) were Carya illinoinensis (Wangneh.) K. Koch. cv. Wichita, C. illinoinensis cv. Western Schley, C. illinoinensis cv. Cherokee, and C. illinoinensis cv. Sioux. The gas chromatography-mass spectrometry analyses revealed that the volatile oils from samples of the different cultivars differ in composition and percentage of their components. b-Curcumene was found as the major constituent of the cv.Wichita oil, whereas germacrene D was the major component of cv. Sioux, cv. Cherokee, and cv. Western Schley. The antimicrobial activity was assayed using the Kirby-Bauer Method by measuring the zone of inhibition of growth. All volatile oils displayed an antimicrobial activity against the tested bacterial strains. On the other hand, only the volatile oil of cv. Wichita showed an antifungal effect on Aspergillus flavus. This work has identified candidates of volatile oils for future in vivo studies to develop antibiotic substitutes for the diminution of human and animal pathogenic bacteria. Nevertheless, the variations of the volatile oil components and antimicrobial potencies of the different studied cultivars, necessitate identifying the cultivars used in future studies.

[METHODS] Describe briefly the main methods or treatments applied; through the use of the Sasang Personality Questionnaire, Eat-26 questionnaire, and assessment of physical fitness (strength, agility, endurance, power, flexibility). SPQ is a 14-question self-report assessment tool for measuring temperament characteristics from the perspective of the Sasang typology. It is divided into three groups: So-Eum, Tae-Eum, So-Yang. Data analysis was performed by one-way ANOVA using statistical software SPSS version 18.0 program. [RESULTS] As to the results, there was a difference in physical fitness and eating attitude according to the SPQ group. Among the variables of physical fitness, So-Yang was significantly higher in back strength (strength) and total fitness score than So-Eum and Tae-Eum. The bulimia and eating behavior were also significantly higher than those of the other groups. [CONCLUSIONS] It was found that the So-Yang group had better physical fitness than the other constitutions but could have had a problem with eating attitude. The utilizing from the study that is able to provide a proper understanding of eating attitude and fitness in SPQ.

This study aims to investigate the difference between physical strength and eating attitude (dieting, bulimia, food behavior) according to BMI (kg/ ㎡ ) among 314 women's university students in through the use Eat-26 questionnaire and assessing physical fitness (strength, agility, endurance, power, flexibility). All data analyses were performed using statistical software SPSS version 18.0 program, along with one-way ANOVA and regression analysis. The study found that there were differences in eating attitudes and fitness (strength) according to BMI group. Moreover, eating attitudes factors affecting each fitness factors were different for each BMI groups. In overweight, behavior had a negative effect on strength, and in the normal group, dieting had a slight positive effect on flexibility. Accordingly, this study found that not only physical fitness and eats attitude were different according to BMI but also eating attitude factors affecting physical fitness factors by BMI group. These results it helps to improve their eating attitudes and fitness to female university students in considering their eating attitude according to body shape.

A Distributed Fog-based Access Control Architecture for IoT

( Seham Alnefaie ),( Asma Cherif ),( Suhair Alshehri ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.12

The evolution of IoT technology is having a significant impact on people’s lives. Almost all areas of people’s lives are benefiting from increased productivity and simplification made possible by this trending technology. On the downside, however, the application of IoT technology is posing some security challenges, among them, unauthorized access to IoT devices. This paper presents an Attribute-based Access Control Fog architecture that aims to achieve effective distribution, increase availability and decrease latency. In the proposed architecture, the main functional points of the Attribute-based Access Control are distributed to provide policy decision and policy information mechanisms in fog nodes, locating these functions near end nodes. To evaluate the proposed architecture, an access control engine based on the Attribute-based Access Control was built using the Balana library and simulated using EdgeCloudSim to compare it to the traditional cloud-based architecture. The experiments show that the fog-based architecture provides robust results in terms of reducing latency in making access decisions.

Seham Mohammed Abd El-Moghny,Manal Salah El-Din,Samah Attia El Shemy 대한배뇨장애요실금학회 2018 International Neurourology Journal Vol.22 No.4

Purpose: To compare the effects of intra-anal biofeedback (BF) and intra-anal electrical stimulation (ES) on pelvic floor muscles (PFMs) activity, nocturnal bladder capacity, and frequency of wet night episodes in children with refractory primary monosymptomatic nocturnal enuresis (PMNE). Methods: Ninety children of both sexes aged 8–12 years with refractory PMNE participated in this study. They were randomly assigned to 3 groups of equal number: control group (CON) that underwent behavioral therapy and PFM training, and 2 study groups (BF and ES) that underwent the same program in addition to intra-anal BF training and intra-anal ES, respectively. PFMs activity was assessed using electromyography, nocturnal bladder capacity was evaluated by measuring the first morning voided volume, and a nocturnal enuresis diary was used for documenting wet night episodes before treatment and after 3 months of treatment. Results: After training, all groups showed statistically significant improvements in all measured outcomes compared to their pretreatment findings. The ES group showed significantly greater improvements in all measured outcomes than the CON and BF groups. Conclusions: Both intra-anal BF training and ES combined with behavioral therapy and PFMs training were effective in the treatment of PMNE, with intra-anal ES being superior to BF training.

How Banks' Resources at the Retail Level Affect Their Output?

ALOTHMAN, Seham,AL-MAHISH, Mohammed Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.12

The study aims to measure the productivity of the Saudi banking sector at the retail level using secondary data for 11 local banks from the period 2015-2019. The study uses an extended version of the Cobb-Douglas production function to account for the fact that as banks openup more retail branches, they will need to employ more labor. The extended Cobb-Douglas production function was estimated using the two-way fixed effect model to account for unobserved heterogeneity across Saudi banks resulting from differences in labor competencies and leadership style. Besides, the model accounts for unobserved heterogeneity among Saudi banks due to the advancement in electronic services over time. The results showed that labor, branches, customers' deposits, and fixed deposits have a positive effect on the total value of generated loans. Conversely, ATM has an insignificant effect on generated loans. The average scale elasticity shows that the Saudi banks at the retail level are operating under decreasing returns to scale. The average marginal rate of technical substitution shows that Saudi banks need at least one ATM to replace one unit of labor at the retail level while keeping the same level of output.

Background: Fragile histidine triad (FHIT) gene is a tumor suppressor gene which involved in breast cancer pathogenesis. Epigenetics alterations in FHIT contributes to tumorigenesis of breast cancer. Objective: Our objective was to study FHIT promoter region hypermethylation in Egyptian breast cancer patients and its association with clinicopathological features. Materials and Methods: Methylation-specific polymerase chain reaction was performed to study the hypermethylation of FHIT promoter region in 20 benign breast tissues and 30 breast cancer tissues. Results: The frequency of hypermethylation of FHIT promoter region was significantly increased in breast cancer patients compared to bengin breast disease patients. The Odd's ratio (95%CI) of development of breast cancer in individuals with FHIT promoter hypermethylation (MM) was 11.0 (1.22-250.8). There were also significant associations between FHIT promoter hypermethylation and estrogen, progesterone receptors negativity, tumor stage and nodal involvment in breast cancer pateints. Conclusions: Our results support an association between FHIT promotor hypermethylation and development of breast cancer in Egyptian breast cancer patients. FHIT promoter hypermethylation is associated with some poor prognostic features of breast cancer.
