This paper aims to quantify the determinants of the Gulf Cooperation Council (GCC) countries' exports by using an augmented gravity model. The gravity model was applied to the six members of the GCC (Kuwait, Saudi Arabia, Bahrain, Qatar, the United Arab Emirates and Oman) with datasets that consist of their major 55 trading partners. The findings of this paper reveal that the product of the exporter's GDP and its trading partner's GDP had a significantly positive effect on the exports of five GCC members, except for Qatar. Distance had a significant and negative effect on the exports of the UAE, Saudi Arabia and Oman, while it had a significantly positive effect on those of Bahrain and Qatar. The exporter's GDP per capita had a significantly positive effect on the exports of Bahrain, the UAE and Oman, while a negative effect on Saudi Arabia's exports. The exporter's population had a significantly positive effect on the exports of all six GCC members, while the importer's population had a significantly positive effect on the exports of Kuwait, Bahrain and Qatar, yet, a significantly negative effect on Saudi Arabia's exports. Borders had an insignificant effect on the exports of the six members. The common language had a significant and positive effect on the exports of Kuwait, Saudi Arabia, Bahrain and Oman. FTAs had a significantly positive effect on the exports of Bahrain and a significantly negative effect on Qatar's and Oman's exports. The membership of the GCC had a significantly positive effect on the exports of Kuwait, Bahrain and Qatar, while it had a negative effect on Saudi Arabia's exports.

Over the last decade, Saudi Arabia has experienced significant economic increases as evidenced by the 30% growth in its gross domestic product; furthermore, the construction industry has increased 10% in the same time period. Due to this significant growth, the construction industry is encountering issues related to construction quality resulting in significant waste and associated environmental impacts. In this research, we applied our previously developed framework that integrates three different methods-Lean, Green, and Six-sigma - to a residential construction complex in Saudi Arabia. Our aim of this case study was to explore the application of the framework in practice to glean quantitative results and further validate the framework. In the case study, we used the developed framework to identify a significant issue related to quality and delays - final completion of 53 residential units was delayed because of failed exterior buildings surfaces. We then used the framework to define the causes behind the defects via a field investigation of the 53 units. Of the defect, construction execution was responsible for 43% of the defect, 31% untrained workers, 19% unfavorable construction weather condition, with 7% accounting for other issues. A procedure was developed in concert with the construction manager and overall developer reducing the amount of rework and waste causes revealed by the field examination and the framework. Although two steps were added to the original construction process to overcome waste causes, still save a lot of resources and reduces environmental impact. In summary, we found that the Lean, Green, Six-sigma framework increased productivity, quality, and reduced waste.

Background: Patients' demographics, presenting clinical and histopathological features for colo-rectal cancer (CRC) are important factors for patients' outcome and disease prognosis. This study aimed to describe the pattern of CRC in terms of patients' demographics, main presenting symptoms and histopathological features in Al Hassa region of Saudi Arabia. Subjects and Methods: A retrospective hospital records-based study which included reviewing of patients' records diagnosed with CRC at three general hospitals in Al Hassa region, Saudi Arabia. A compilation form was designed to collect information regarding socio-demographics, age at diagnosis; referral sites and the main presentations at CRC diagnosis. sites and the main presentations at CRC diagnosis. Histopathological reports were reviewed to delineate the main cytopathologic features, prominent cytological characteristics, the presence of predisposing pathology, and disease stage. Results: Of the 142 cases with CRC, 15.5% and 33.1% were affected before 40 and 50 years of age respectively. Emergency rooms were main referral sites for CRC cases (31.0%). Right colon was affected in 16.9% while left colonic lesions accounted for 62.7%. Intestinal obstruction was the main presentations (41.5%), and 26.1% presented with symptoms indicating distant metastastic lesions. Adenocarcinoma was the predominant pathological lesions (86.6%). Metastastic CRC was diagnosed in 62.7%. Duke's staging showed that 22.5% and 40.1% of lesions were classified into C and D categories respectively. Conclusion: Saudi patients with CRC present late with distant metastasis, and advanced disease stage. A sizeable proportion of patients developed the lesions at relatively young age. Screening recommendations should be enacted and revised in response to current change with younger age of affection.

In Saudi Arabia, cancer of breast is ranked the most frequent neoplasm and second source of cancer death in the female population. Breast cancer (BC) fast diagnosis, prognosis and medication management necessitate, these days, immunohistochemistry (IHC) assessment of hormone receptors and HER2 expression profile. The present report defines the IHC profile of ER, PR and HER2 in Saudi female breast neoplasms of ductal and lobular types and associations ER, PR and HER2 expression patterns with various clinicopathological factors (age, type of tumor, size, laterality, histological grade, and involvement of axillaries lymph nodes). Ninety nine cases of breast tumors were recruited from the pathology department archive of King Abdulaziz University Hospital, Kingdom of Saudi Arabia. ER, PR and HER2 expression was assessed using IHC staining. Ductal carcinomas with a variety of histological grades constituted 88 (88.8%) of total cases. Seventy four (77.8%), 59 (62.1%), and 35 (36.8%) of ductal carcinomas showed positive staining for ER, PR and HER2, in that order. Remaining breast cancer cases were four (4%) lobular carcinomas and two (2%) mixed form of ductal and lobular types, which were ER+, PR+, and HER2-. Breast cancer expression pattern of ER, PR and HER2 in Saudi female is different from that of Tunisian and Jordanian female populations and closer to the expression pattern of Egyptian, Lebanese, Iraqi and western country females. Furthermore, the present study found two IHC patterns of breast cancer ER+/PR-/HER2+ (5%) and ER+/PR-/HER2- (11.1%), which had not been reported in other Arabic studies. Thus the rates of IHC expression patterns in breast cancer show some variation among Arabic female populations.

Hydrogeological survey and geophysical prospecting have been carried out in Saudi Arabia for the purpose of finding groundwater in the soil and rock at the request of General trading company in Jeddah, Saudi Arabia. The surveyed area is located on $38^{\circ}-39^{\circ}$ 30' in longitude and $26^{\circ}-26^{\circ}$ 30' in latitude. The topography of this area is dominated by northwest southeast mountain range composed mostly of precambrian rocks and basalt of tertiary period. Geology is mainly composed of greenstone, granite, andesite, diorite rhyolite of pre-cambrian era and sandstone of cambrian period which are underlained by basalt and andesite of tertiary period and alluvium of quaternary unconformably. The instruments used in this investigation are TR-18B2 radioactivity unit which isjapanese patented and A.C. Terrameter, a resistivity meter manufactured by ABEM of Stockholm, Sweden. Radioactivity method has been conducted along the Alula-Khaybar road, totally 164Km by the car-borne. As a result of the above survey 16 places have been selected and these anomalies show 1.2N-1.6N compared to background of each area in intensity with width of 10-50m. Resistivity vertical profiling which made use of Schlumberger configuration method has been made over selected areas by radioactivity method to provide hydrogeological information for a water resources survey. The result of resistivity shows that good aquifers are located in the western part of surveyed area where sedimentary rock is distributed. The strata showing 10-50, ${\Omega}-m$ in resistivity are thought to be waterbearing layer. The variations in aquifer resistivity found, are thought to be due to verying clay content, which could be related to aquifer yield. It has proved impossible to detect small salinity variation in the buried aquifer by geophysics. As a result of resistivity prospecting 10 places are recommended to be drilled at the anomalies as shown attached map. yields from the proposed holes have been estimated approximately from $20m^3$ to $200m^3$ per day. Prior to drilling for groundwater, test boring using ${\c}4"$ should be drilled in order to obtain more reliable hydrogeological information for the construction of perfect wells.ells.

Smoking is recognized as a health problem worldwide and there is an established tobacco epidemic in Saudi Arabia as in many other countries, with tobacco users at increased risk of developing many diseases. This cross sectional study was conducted to assess the prevalence of oral mucosal, potentially malignant or malignant, lesions associated with tobacco use among a stratified cluster sample of adults in Jeddah, Saudi Arabia. A sample size of 599 was collected and each participant underwent clinical conventional oral examination and filled a questionnaire providing information on demographics, tobacco use and other relevant habits. The most common form of tobacco used was cigarette smoking (65.6 %) followed by Shisha or Moasel (38.1%), while chewing tobacco, betel nuts and gat accounted for 21-2%, 7.7%, and 5% respectively. A high prevalence (88.8%) of soft tissue lesions was found among the tobacco users examined, and a wide range of lesions were detected, about 50% having hairy tongue, 36% smoker's melanosis, 28.9% stomatitis nicotina, 27% frictional keratosis, 26.7% fissured tongue, 26% gingival or periodontal inflammation and finally 20% leukodema. Suspicious potentially malignant lesions affected 10.5% of the subjects, most prevalent being keratosis (6.3%), leukoplakia (2.3%), erythroplakia (0.7%), oral submucous fibrosis (0.5%) and lichenoid lesions (0.4%), these being associated with male gender, lower level of education, presence of diabetes and a chewing tobacco habit. It is concluded that smoking was associated with a wide range of oral mucosal lesions, those suspicious for malignancy being linked with chewable forms, indicating serious effects.

Purpose: This research aims to examine gender preferences for men and women advertising models in Saudi advertisements. Saudi Arabia is known as one of the most gender-segregated society in the world, and it has gender-specific roles, characteristics, and behaviors that are undesirable for the other gender. Methodology: The questionnaire was developed with the help of earlier studies on perceptions towards advertising models and validated by a jury of experts and focus groups. The gender preferences for ten product categories (including automobiles, baby care products, cigarettes, cosmetics for women, fashion, food & beverages, motorcycles, personal care for men, personal care for women, sporting goods) were examined for men and women models. Similarly, three personal preferences characteristics for both genders (face beauty, voice quality, and Islamic dress), two characteristics for women models (body shape, femininity), and two characteristics for men models (height-weight balance, masculinity) were examined for men and women models separately. Finally, a survey was conducted to solicit responses from respondents (N=412). Findings: Results indicated significant gender preferences for gender-specific product categories and typical gender stereotypes in advertising models. Men models were preferred in men-specific products, and women models were required in women-specific products. Some product categories (including personal care for men and sporting goods) were ranked higher for men advertising models, while for women advertising models, other product categories (including personal care for women and cosmetics for women) were ranked higher. Masculinity was ranked highest as the preferred personal characteristic for men advertising models, while voice quality was highest for women advertising models. Finally, there is a significant difference between the preferred personal characteristic for men and women advertising models for three characteristics, including face beauty, Islamic dress, and masculinity and femininity. Implications: Saudi Arabia is a unique society with predominantly unique cultural dominance. Consequently, local culture greatly influences advertisements. It has stereotyped gender roles even in advertisements. This study will establish a baseline for further research on the subject area.
