Background: Cervical cancer is the second most common cancer among females and also the most preventable. In the literature there is abundant evidence that awareness regarding cervical cancer and its prevention is low in the developing countries. Medical students are the future health professionals and can play an important role in increasing awareness among the general population. To assess the knowledge regarding symptoms, risk factors and prevention of cervical carcinoma among medical students in th Kingdom of Saudi Arabia, the present study was planned. Materials and Methods: This cross-sectional study was conducted using a self-administered questionnaire with students at the College of Medicine, King Faisal University, Al-Ahsa, KSA, from December 2012 to May 2013. Results: The responses of 188 students (males 111, females 77) in their second, third, fourth, and fifth years were recorded and used in the data analysis. The majority of the students were not aware of the early warning signs, symptoms and risk factors. On average, only 43.7% males and 56% of females were aware about the early signs and symptoms whereas 51.4% males and 57.8% females had knowledge about the risk factors of cervical cancers. Some 55% males and 46.8% females were unable to select the correct answer regarding human papilloma virus (HPV) infection as the cause of cervical cancer. Majority of the students (67%) were not aware about the availability of vaccine against HPV. Conclusions: Lack of knowledge regarding early signs and symptoms, risk factors and prevention of cervical cancer was observed in the present study.

Cholera represents an ongoing threat to many low-income and middle-income countries, but some cases of cholera even occur in high-income countries. Therefore, to prevent or combat cholera outbreaks, it is necessary to maintain the capacity to rapidly detect cholera cases, implement infection control measures, and improve general hygiene in terms of the environment, water, and food. The 2 cases, 1 imported and 1 secondary, described herein are broadly indicative of areas that require improvement. These cases were missed at the primary health care stage, which should be the first detection point even for unusual diseases such as cholera, and the absence of strict infection control practices at the primary care level is believed to contribute to secondary cases of infection. This report also encourages countries to ensure that rapid diagnostic stool tests are available to enable quick detection, as well as to provide information to people travelling to areas where cholera is endemic.

Background: There is a scarcity of information about the proportion of the adult Saudi population that meet the recommended guidelines of physical activity (PA) to reduce cancer risk. Moreover, their awareness about the role of PA in cancer prevention is unclear. Objectives: This cross-sectional study aimed at estimating the proportion of adult Saudis meeting the PA guidelines, specifically those recommended by American Cancer Society (ACS) for cancer prevention, and to assess the public awareness about the role of PA in cancer prevention. Materials and Methods: Using a multistage sampling method, 2,127 adult Saudis of both genders were recruited from 6 urban and 4 rural primary health care centers in Al Hassa, Saudi Arabia. Participants were personally interviewed to gather information about their sociodemographic characteristics, searching activity about PA and cancer, and the time spent in leisure time PA (moderate and vigorous)/week using the Global Physical Activity Questionnaire with show cards. Finally, items about the role of PA in cancer risk reduction were inquired. Results: Of the included participants, 11.6% met the recommendations for cancer prevention (${\geq}45$ minutes of moderate-vigorous PA activity/${\geq}5$ days/week or 225 minutes/week). Multivariate regression showed that being male (AOR=1.49, CI=1.09-2.06), <20 years of age (AOR=3.11, CI=2.03-4.76), and unemployed (AOR=2.22, CI=1.57-3.18) were significant predictors for meeting PA recommendations for cancer prevention. Only 11.4% of the sample indicated correctly the frequency and duration of PA required for an average adult to be physically active and while >70% of them indicated the role of PA in prevention of hypertension, coronary heart disease and lowering elevated blood cholesterol, only 18.6% and 21.7% correctly mentioned the role of PA in reducing colon and breast cancer risk, respectively. Poor knowledge was found among those with less than college education and aged ${\geq}50$ years. The level of knowledge was significantly positively correlated with total leisure time PA of the participants. Conclusions: A minority of adult Saudis in Al Hassa was aware about the role of PA in cancer prevention and engaged in sufficient LTPA for cancer risk reduction benefits, highlighting the need for public health actions to include policies and programs that address factors deterring their participation in LTPA and increasing their awareness with remedies to manage the prevalent misconceptions.
On the Universality of Auxiliary Verbs
Nasser Al-Horais 세종대학교 언어연구소 2012 Journal of Universal Language Vol.13 No.1
Cross-linguistically, it has often been observed that there is no any specific language-independent formal definition that can be used to determine the characterization of any given element as an auxiliary verb. This paper, though it agrees to some extent with this observation, argues that there is still room to find some universal properties that help us end up with the conclusion that auxiliaries and lexical verbs are two distinct types of syntactic entities. To this end, this paper describes the characteristics necessary for what is to count as an auxiliary verb. Having done that, the paper turns to illustrate the most common properties that can be found among languages in order to find a clear universally agreed definition of an auxiliary verb.
Intra-Gulf Cooperation Council : Saudi Arabia Effect
Nasser Al Mawali 세종대학교 경제통합연구소 2015 Journal of Economic Integration Vol.30 No.3
The main thrust of this study is to investigate the extent to which Saudi Arabia’s economic growth acts as an engine of growth for the Gulf Co-operation Council region. The estimation results of Gulf Cooperation Council for the last three decades suggest that the growth of Saudi Arabia, along with the growth of United Arab Emirates and Bahrain, is positive and statistically significant in explaining the overall growth of the Gulf Cooperation Council region. The main policy implication of these findings is that the positive intra-economic growth of these countries should serve as further motivation for the intra-regional integration of the Gulf Cooperation Council.
On Negation and Focus in Standard Arabic: Interface-based Approach
Nasser Al-Horais 세종대학교 언어연구소 2017 Journal of Universal Language Vol.18 No.1
This paper addresses the interface between syntax and information structure by interpreting focus under negation. To this end, data will be examined from the Arabic negative marker laysa, which exhibits interesting focus features that broaden our knowledgeof syntactic and semantic aspects of negation and deepen our understanding of what information structural effects play a role at the interface. Focus typology can be expressed by laysain its two major types, namely the information focus and contrastive focus, resulting in three different ways in which negation and focus can interact at the Syntax-Information Structure Interface. These ways are of three different readings of focus (wide, bound, and free). Each of these foci involves a different derivation which reflects how the autonomous notions of information structure–topic, focus, and contrast–interact in systematic ways with syntax as shown by the proposed minimalist analysis for each type.

Control and Modulation of Three to Asymmetrical Six-Phase Matrix Converters based on Space Vectors
Al-Hitmi, Mohammed A.,Rahman, Khaliqur,Iqbal, Atif,Al-Emadi, Nasser The Korean Institute of Power Electronics 2019 JOURNAL OF POWER ELECTRONICS Vol.19 No.2
This paper proposes the modulation and control of a three-to-six-phase matrix converter with an asymmetrical six-phase output. The matrix converter (MC) outputs consist of two sets of three-phase spatially shifted by $30^0$, where the two sets have two isolated neutrals. The space vector approach is considered for the modeling and subsequent modulation of the three-to-six phase MC. The intelligent selection of voltage space vectors is made to synthesize the reference voltages and to obtain a sinusoidal output. The dwell times of selected voltage space vectors are adjusted in such a way that the effect of the second and the third auxiliary plane vectors (i.e., x1-y1, and x2-y2) are nullified. To achieve the maximum output voltage gain and to ensure that no reactive power is drawn from the utility supply, the input side power factor is maintained at unity. Nevertheless, the source side power factor is controllable. The modulation technique is implemented in dSPACE working in conjunction with a FPGA. Hardware results that validate the proposed control algorithm are discussed.
