Reem Adnan AL Kharouf,Abdel Rahman Alzoubaidi,Mazher Jweihan 대한공간정보학회 2017 Spatial Information Research Vol.25 No.1

Spatial data infrastructure had ensured the availability of geospatial data over the local and global boundaries to be used in more flexible and efficient manner. With the enhancement in web service technologies the need of geoprocessing the geospatial data from various heterogeneous sources over the web, to produce valuable information is of great interest among research community. Towards this implementation of geoprocessing web, open geospatial consortium (OGC) has provided several web processing service standards for handling the geoprocess over the web. Most of the current existing geoprocessing web platforms inherit the capabilities of these web processing service standards and protocols define by OGC. However there exist several challenges that includes, growing intensity of data, high performance computing, real time data processing, and to provide robust, reliable, and cost effective geoprocess services to the end user. The future of geo-processing lies in the adoption of cloud computing to overcome the existing challenges. Characteristics of cloud computing including scalability, elasticity, pay-per-use, and self provisioning, offers a more reliable, on demand, and cost effective geoprocessing services to its end user. In this context the study makes an attempt to analyze the current state of geoprocessing services over cloud, with exiting GIS Cloud platform solutions in the literature to counter the challenges of GIS cloud. Furthermore, study proposes a design and architectural framework for geoprocessing over Cloud platform, based on OGC standards. The architecture includes developing geoprocessing service, and data management services as an essential part while storing/processing the geospatial data from heterogeneous sources. The architecture model including data management and geoprocessing can be bind together in a cloud platform to have an on demand service as per the requirement of end user.

Policy borrowing and developing knowledge economies in GCC countries: a critique from a Human Capital Theory perspective

Reem Khalid Abu-Shawish,Michael H. Romanowski,Tasneem Amatullah 서울대학교 교육연구소 2021 Asia Pacific Education Review Vol.22 No.1

Globalization presents Gulf Cooperation Council (GCC) countries with opportunities for economic growth and transformation, as many of these nations face economic challenges such as the need for a diversified knowledge-based economy because of the finite resource of hydrocarbons. This requires the development of human capital providing workers with new and advanced skills and competencies. Education has become increasingly important on national agendas in the GCC, leading to an increase in transferring educational reforms often founded on Human Capital Theory (HCT). This article examines how HCT is embedded in the development of knowledge economies and reforms in many GCC countries and identifies the possible differences between western understandings of Human Capital Development (HCD) and GCC nations. In particular, the article addresses cultural preservation, specifically identity and language, against the backdrop of HCD in the GCC nations. Discussion centers on HCD from a local perspective raising concerns about HCT as a guiding educational theory in the GCC. This is followed by several suggestions for policymakers to consider when developing an education system that includes the skills deemed necessary for economic development while simultaneously preserving national identity and the Arabic language.

Unique Spatial Compositions of Traditional Cairene Courtyard Houses in Cairo

Reem Abdelkader(림 압델카데르),Park Jin-ho(박진호) 대한건축학회 2017 대한건축학회 학술발표대회 논문집 Vol.37 No.1

Architecture’s identity had been reflecting the characteristics of country’s people, environment, and society’s features. Due to the recent globalization, the unique architecture identity of each country has been faded so that it has become hard to figure out each country’s unique local and regional identity. In particular, traditional houses in Cairo, known as Cairene houses, are considered as an iconic style of Cairo’s architectural history. The objective of this paper is to underly the principles of spatial compositions which are extracted to explain unique spatial characteristics in these houses. Through the analysis, it is expected to characterize distinct spatial quality appeared in traditional Cairene courtyard houses in Cairo, exposing identity and values of the houses.

Kinematic geometry of a line trajectory in spatial motion

Reem A. Al-Ghefari,Rashad A. Abdel-Baky 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.9

This paper derives the equations of line-trajectory in spatial motion by means of the E. Study dual-line coordinates. A special emphasisgoes to the second-order motion properties for deriving a new proof of the Disteli formulae. As an application concise explicit expressionsof the inflection line congruence are directly obtained. Also, a new metric is developed and used to investigate the geometricalproperties and kinematics of line trajectory as well as Disteli axis. Finally, a theoretical expressions of point trajectories with special valuesof velocity and acceleration, which can be considered as a form Euler-Savary equation, for spherical and planar motions are discussed.

Mobile Payments from Merchants' Perspective: An Empirical Study Using the TAM Model in Saudi Arabia

Altwairesh, Reem,Aloud, Monira International Journal of Computer ScienceNetwork S 2021 International journal of computer science and netw Vol.21 No.8

This study aims to examine the factors that affect the intention of merchants to adopt mobile payments in Saudi Arabia. The underlying model used in the study is the technology acceptance model, which includes two factors: perceived ease of use and perceived usefulness. The effects of trust, cost, and compatibility are also examined because these are among the common factors used based on the literature. An online questionnaire was completed by 242 merchants in Saudi Arabia who had already adopted mobile payment services. A significant relationship was identified between perceived usefulness and compatibility in terms of merchants' intention to adopt mobile payment systems, while an insignificant relationship was identified with perceived ease of use, trust, and cost.

Molecular identification of forensically important beetles in Saudi Arabia based on mitochondrial 16 s rRNA gene

Alajmi Reem,Abdel‐Gaber Rewaida,Haddadi Rania 한국곤충학회 2020 Entomological Research Vol.50 No.7

Forensic science uses scientific methods to help the scientists who study evidence to assist in the solving of crimes. Coleoptera is the most diverse and speciose group of insects that have an important role in many scientific fields especially forensic entomology. In addition, it is difficult to morphologically identify and discriminate between them. In the present study, the molecular analysis using mitochondrial DNA information was conducted to swiftly and accurately identify the recovered Coleoptera species. A molecular identification method involving a 221-bp segment of the 16 s ribosomal RNA (16 s rRNA) gene from three beetle species, collected from a rabbit carcass, was evaluated. The analysis with maximum likelihood method recovered a generally well supported phylogeny, with most currently accepted taxa and species groups as monophyletic. These results will be instrumental for the implementation of the Saudian database of forensically relevant beetles.

Study of 100 food service workers who were positioned in low and middle levels of their organizations used a multidimentional approach to examine the effects of multiple predictors from three categories; 1) job characteristics, 2) organizational characteristics, and 3) worker characteristics on job satisfaction. Questionnaire were used to collect information from respondents regarding their individual and group characteristics in addition to characteristics of their jobs and their job satisfaction. The relationship between job satisfaction and each predictor in the three categories was calculated through multiple regression. A statistical method, hierarchical sums of squares, was also used to determine which category included the best set of predictors of job satisfaction. The results indicated that job category was the strongest predictor of three categories that were investigated. And then, this study discussed the implications of the findings.

A Qualitative Study of Intervention for Adolescents with Severe Internet Addiction

Ha-Reem Chang 한국자치행정학회 2016 한국자치행정학보 Vol.30 No.1

한국 청소년의 인터넷 이용에 대한 활용과 관심이 높아지면서 인터넷 중독률에 대한 우려는 최근 다양한 학문영역에서 논의되고 있다. 높은 인터넷 이용률과 함께 등장한 청소년 인터넷 중독에 대하여 정부의 역할과 책임이 강조되는 것에 비해, 정부의 인터넷 중독 집중 치료기관인 RESCUE School이 제공하는 치료프로그램은 무엇인지, 치료과정의 갈등요소는 무엇인지, 중재가 실제적으로 효과가 있는지 등에 대한 구체적인 논의는 매우 미흡한 실정이다. 본 연구의 목적은 RESCUE School에서 치료받은 청소년의 치료과정과 경험, 부모의 경험을 살펴봄으로써 실제 치료프로그램의 효과성을 질적 연구를 통해 논의해보고자 하는 것이다. 이에 본 연구는 RESCUE School에 참가했던 인터넷 중독 고위험군 청소년과 그들의 부모를 대상으로 심층인터뷰를 실시하였다. McMillan & Morrison(2006)의 이론에 근거하여 자아, 가족, 현실/가상세계에서 인터넷 중독의 의미와 치료경험을 분석하였다. RESCUE School 프로그램을 통한 치료경험은 능동적 자아, 가족관계증진, 현실세계의 긍정적 측면 및 가상세계의 부정적 측면에 대한 인식이 높아진 것으로 나타났다. 본 연구결과는 고위험군 인터넷 중독 청소년들의 경험 분석을 통해 RESCUE School프로그램이 치료를 위한 개입전략으로서 기능하고 있다는 점을 밝히고 있다. The increasing public concern about Internet Addiction has become a hot issue in recent years and it is always accompanied by how to define and cope with problem. Adolescents are particularly susceptible to the lure of the internet, and they are described as being obsessed with the internet. This study aimed to investigate the intervention programme called RESCUE School with attempts to provide some insights from narratives perspective. The narratives in this study provided insights into ways of feeling, relating and acting in the interviewees’ personal experiences based on four spheres theorized by McMillan & Morrison(2006). The findings revealed that people addicted to the internet suffer the standard problems associated with addictive behaviours. After the RESCUE School, the participants experienced active themselves, improvement of relationship with family, better real communities and worse virtual communities. The study aimed to provide an opportunity for academics, health care professionals, teachers, social workers, community leaders and members from parent school associations, government officials and the general public to better understand the signs of internet addiction and the preventive responses.
