본 연구의 목적은 중력모형을 이용하여 걸프협력회의(GCC) 6개국 수출의 결정요인이무엇인가를 정량적으로 분석하는 것이다. 중력모형을 이용하여 GCC 회원국인 쿠웨이트, 사우디아라비아, 바레인, 카타르, 연합아랍에머리트 및 오만의 55개 주요 무역국과의 수출 결정요인을 분석하였다. 본 연구의 주요 분석 결과는 다음과 같다. 수출국의 GDP와 수입국의 GDP의 곱이 카타르를 제외한 GCC 5개국의 수출에 통계적으로 유의한 수준의 긍정적 영향을 준 것으로 분석되었다. 거리는 아랍에메리에트(UAE), 사우디아라이바 및 오만에 부정적인 영향을 준 것으로 분석된 반면에, 바레인과 카타르의 수출에는 긍정적인 영향을 준 것으로 분석되었다. 수출국의 1인당 GDP는 바레인, UAE와 오만의 수출에는 통계적으로 유의한 수준의 긍정적인 영향을 준 것으로 분석되었지만, 사우디아라비아의 수출에는 부정적인 영향을 준 것으로 분석되었다. 수출국의 인구는 GCC 6개국 모든 나라의 수출에 긍정적인 영향을 준 것으로 분석되었다. 이와 대조적으로 수입국의 인구는 쿠웨이트, 바레인과 카타르의 수출에는 긍정적인 영향을 주었지만 사우디아라비아의 수출에는 부정적인 영향을 준 것으로 분석되었다. 국경은 GCC 회원국 중 어느 나라의 수출에도 유의한 영향을 주지 못한 것으로 분석되었다. 공동언어의 경우 쿠웨이트, 사우디아라비아, 바레인 및 오만의 수출에 긍정적인 영향을 준 것으로 분석되었다. 자유무역협정(FTA)는 바레인의 수출에만 긍정적인 영향을 준 것으로 분석되었으며, 카타르와 오만의 수출에는 부정적인 영향을 준 것으로 분석되었다. GCC회원국자격은 쿠웨이트, 바레인 및 카타르의 수출에는 긍정적인 영향을 주었지만 사우디아라비아의 수출에는 부정적인 영향을 준 것으로 분석되었다.

This study seeks to reveal why the U.S. House Democrats showed different levels of support in the voting of the U.S.-Morocco FTA, U.S.-Bahrain FTA, and U.S.-Oman FTA. Existing studies focusing on the constituency or members' ideology do not properly account for the variance of these three FTA voting results. All of these FTAs, however, were promoted as a part of the president's foreign policies. If so, FTA support in Congress could depend on representatives' evaluation of the presidential foreign policy. Based on this, the study analyzes how representatives' evaluation of President Bush's foreign policy changed according to the period of the three FTA votes. The vote on the FTAs has been influenced by their evaluation of the presidential foreign and national security policies.

This article introduces the notion of almost deferred weighted convergence, statistical deferred weighted almost convergence and almost deferred weighted statistical convergence for real valued sequences. Further, with the aid of interesting examples, we investigated some relationships among our proposed methods. Moreover, we prove a new type of approximation theorem and demonstrated that our theorem effectively extends and improves most of the earlier existing results. Finally, we have presented an example which proves that our theorem is a stronger than its classical versions.

Background: Celiac disease (CD) is a chronic autoimmune enteropathy. It results from genetic predisposition and exposure to gluten-containing food. The prevalence and presentation of CD vary among populations. Purpose: This study aimed to describe the prevalence and clinical characteristics of CD in children in Bahrain. Methods: We retrospectively reviewed the medical records of children diagnosed with CD in the pediatric department, Salmaniya Medical Complex, Bahrain, in 1988-2018. Their clinical, biochemical, serological, and histopathological findings were documented. Adherence to the recommended gluten-free diet (GFD) was assessed. Results: Of 86 patients with CD, 67 were included. The CD prevalence was 0.02%. A significant increase in prevalence in the last decade was observed (P<0.0001). Thirty-eight patients (56.7%) were males. The median (interquartile range) age at presentation was 4.45 (1.5-7.3) years. A family history of CD was positive in 13 out of 43 patients (30.2%). Pallor and failure to thrive were the most common presentations. The most frequent associated disease was iron-deficiency anemia in 23 patients (69.7%). Positive serology was found in 32 of 45 patients (71.1%). Marsh-Oberhuber type III was found in 16 of 35 patients (45.7%). Seropositive patients were significantly older (P=0.025) and had more severe duodenal histology (P=0.002). Adherence to GFD was poor in 27 patients (64.3%). Conclusion: This study revealed a significant increase in CD prevalence over the last decade. Atypical presentations were frequent. Most patients had poor adherence to GFD.

Renewable energy or green energy is a hot issue in theses days. Since wind resource can be endlessly supplied by nature, researchers and common people are interested in study how to use that resource at home or company. Especially, many architects have tried to integrate wind power generator for a part of building. So in this paper, three buildings installed wind power turbine are targed to CFD analysis and these buildings are Bahrain trade center, Discovery tower, and Pearl river tower. Bahrain trade center is the first building installed real wind turbine, Discovery tower is constructing at Texas, and Pearl river tower is designed and proved by china researchers. These buildings have very different type of wind power turbine and each turbine has different conditions f3r best power generation. Therefor this paper will focus on characteristic shape of buildings, wind power turbine type, and expected purpose of construction. Moreover, CFD analysis will show wind flow pattern and wind speed while wind is passing through wind turbine of three tall buildings. CFD analysis for three buildings make comparison the wind flow patterns with experimental result.

The main aim of this investigation is to explore the relationships between emotional exhaustion, depersonalization, personal accomplishment, and job satisfaction among employees working in the banking sector. A total of 214 respondents were surveyed for the purpose of this investigation and selected randomly from different banks located in the Kingdom of Saudi Arabia (K.S.A.). Job Burnout Inventory developed by Maslach and Jackson (1981) was taken into consideration to assess emotional exhaustion, depersonalization, and sense of personal accomplishment, and job satisfaction scale was used to measure the degree of satisfaction level of the employees. The collected data were analyzed by means of descriptive and inferential statistics with the help of statistical Package for Social Sciences (SPSS). The most eye-catching findings of the investigation revealed that emotional exhaustion had the greater mean as compared to depersonalization and personal accomplishment. The inverse significant correlation has been observed between emotional exhaustion, depersonalization, and job satisfaction while positive and significant relationship was observed between personal accomplishment and job satisfaction. Further, the result of the investigation from regression test indicates that the relationship existed between emotional exhaustion, depersonalization, personal accomplishment, and job satisfaction among employees working in the banking sector in the Kingdom.
