The Archaeological Records of Oman: The Challenge of Information Management

Although Oman’s National Heritage Protection Law (NHPL) of 1980 explicitly emphasises the importance of recording the country’s archaeological resource, no major attempt has yet been made to quantify it in a truly comprehensive way. And what few attempts have been made to do so in consistent and standard ways have seen attention limited to specific geographical regions and usually with research objectives that did not include recording. With Oman’s accelerating pace of modernization since the 1970s, parts of the nation’s archaeological resource have become exposed to and endangered by both natural and human factors. Some components have been partially destroyed, others increasingly threatened. It is, therefore, beyond dispute that the establishment of a national archaeology record is an urgent need. In response to such a reality, this paper highlights the neglected role of the archaeological records in the practices of both researchers and management. It reviews the present practices of the relevant bodies when compiling, verifying, storing, managing and exploiting information related to the nation’s archaeological resources. The paper also examines existing records in terms of their aims, scope, development, usage, limitations and adequacy. Finally, it suggests ways to enhance current practice and establish a national record of archaeological resources

IMPROVING BREAST CANCER AWARENESS THROUGH AN EXPERT SYSTEM (18)

The mission of this research paper is to demonstrate the development of a breast cancer awareness and diagnosis expert system utilizing human experts’ knowledge that focuses on users’ lifestyle, personal and family history, and various symptoms of breast cancer to raise awareness about this disease and help early detection. Breast cancer is considered a second kind of cancer impacting women’s lives globally, and it affects about twenty percent of women in Oman, mainly due to a lack of awareness and early detection programs in some places and to cultural barriers. This study developed a simple breast cancer awareness and diagnosis expert system prototype to raise awareness among the female population in particular and to help diagnose breast cancer at early stages for better success rates in treatment. The system has been developed by using a web content rule-based expert system shell. Subsequent to the development of the system, it was evaluated by various users to check its benefits and advantages through a set of evaluation criteria. The potential users noted the advantages and limitations of the system

Evaluation of the Quality of Academic Programs from the Perspective of Students in the College of Arts and Social Sciences at Sultan Qaboos University

Objectives: This study assesses the quality of academic programs in the College of Arts and Social Sciences at Sultan Qaboos University from the students' perspective. It examines variations in perceived program quality among the college's scientific departments. Methods: The study employs a descriptive survey approach, utilizing a questionnaire with 48 items across five dimensions to gauge the quality of academic program performance from the perspective of first-stage undergraduate students. A five-point Likert scale measures students' attitudes. The study population comprises all first-stage undergraduate students with a minimum of 75 credited hours across various programs, totaling 761 students for the spring semester of 2020. It consists of 336 students. Results: The overall evaluation of the quality of academic programs in the college, from the students' perspective, was rated as "moderate." It revealed that the quality levels of academic programs in the departments of Media, Arabic Language and Literature, English Language and Literature, and Geography were higher than the remaining departments: History, Information Studies, Tourism, Music, and Musicology. It identified significant differences in response means across all dimensions of academic program quality based on scientific department. No statistically significant differences were found in student responses across quality dimensions when considering the variable of gender. Conclusions: The study suggests implementing targeted programs in scientific departments to maximize the advantages of academic accreditation and improve academic program quality. It also recommends creating effective monitoring programs to address feedback from accreditation bodies and international evaluators, focusing on identifying strengths, weaknesses, and optimal methods for enhancement

Development and performance evaluation of a solar tunnel date dryer in Oman

Taking into consideration the date harvesting and landholding capacities of the marginalized rural farmers in Oman, a 12 meter long and 2 meter wide tunnel was designed and constructed to dry about 180-200 kg of freshly harvested dates per batch. Half of the tunnel base was used as a flat plate air heating solar collector and the other half as a dryer. The drying air was forced from the collector region (South side) to the drying region (North side) of the half circled tunnel where the product is to be dried. The drying temperature could be easily raised by some 5-30 oC above the ambient temperature inside the tunnel at an air velocity of approximately 0.5 m/sec. The test was conducted with 190.2 kg freshly harvested dates with initial moisture content of 32.8% (wet-basis) to analyze the performance of the dryer. The dates were dried to a final average moisture content of 18.6% (wet-basis) within two days (20 hours). The results indicated that the drying was faster in a solar tunnel dryer than the natural open air sun drying. It was possible to reach the moisture content level for safe storage within less than two days (20 hrs) with a solar tunnel dryer and 5-7 days in open air natural sun drying. The improvement in the quality of dates in terms of color and brightness was distinctly recognized

Safeguarding Oman’s Cultural Heritage: Legislative Perspective: Safeguarding Oman’s Cultural Heritage: Legislative Perspective

Oman’s cultural heritage is protected by a number of laws, the most important of which is the Cultural Heritage Law (CHL), which was issued in 2019 as a replacement for the National Heritage Protection Law (NHPL) that was in force since 1980. This paper reviews the protection and management of various types of cultural heritage under both these laws and other relevant national legislative tools. It discusses the aptness and adequacy of these laws to manage this heritage in light of the unprecedented development that the country has been witnessing since 1970. The study concludes that there are a number of aspects that need to be considered for the refinement and reformation of extant laws. For example, the legal and practical challenges that can arise from having a single law must be considered to manage and protect all types of cultural heritage. Also, the practicability of having two different organizations to manage both tangible and intangible heritage must be assessed. Finally, the study proposes to include the protection of cultural heritage in laws that have a direct and indirect relationship. Finally, it suggests the reconsideration of the separation of the bodies concerned with heritage from those concerned with culture.   Keywords: Sultanate of Oman; cultural heritage; tangible heritage; intangible heritage; law

Diagnostic Value of Electrocardiographic T Wave Inversion in Lead aVL in Diagnosing Coronary Artery Disease in Patients with Chronic Stable Angina

Objectives: The clinical value of T wave inversion in lead aVL in diagnosing coronary artery disease (CAD) remains unclear. This study aims to investigate the correlation between aVL T wave inversion and CAD in patients with chronic stable angina.Methods: Electrocardiograms (ECGs) of 257 consecutive patients undergoing coronary angiography were analyzed. All patients had chronic stable angina. All patients with secondary T wave inversion had been excluded (66 patients). The remaining 191 patients constituted the study population. Detailed ECG interpretation and coronary angiographic findings were conducted by experienced cardiologists.Results: T wave inversion in aVL was identified in 89 ECGs (46.8%) with definite ischemic Q-ST-T changes in different leads in 97 ECGs (50.8%). Stand alone aVL T wave inversion was found in 27 ECGs (14.1%) while ischemic changes in other leads with normal aVL were identified in 36 ECGs (18.8%). The incidence of CAD was 86.3%. Single, two- and multi-vessel CAD were found in 38.8%, 28.5% and 32.7% of cases respectively. The prevalence of left main, left anterior descending, left circumflex and right coronary arteries were 4.7%, 61.2%, 29.3% and 44.5%, respectively. T wave inversion in aVL was found to be the only ECG variable significantly predicting mid segment left anterior descending artery (LAD) lesions (Odds Ratio 2.93, 95% Confidence Interval 1.59-5.37, p=0.001).Conclusion: This study provides new information relating to T wave inversion in lead aVL to mid segment LAD lesions. Implication of this simple finding may help in bedside diagnosis of CAD typically mid LAD lesions. However, further studies are needed to corroborate this finding

Hemorrhagic Cardioembolic Stroke Secondary to a Left Ventricular Thrombus: a Therapeutic Dilemma

Cardiogenic embolism is a major cause of stroke and often leads to significant morbidity and mortality. Despite the recent advances in our understanding of the pathophysiology of stroke and its risk factors, diagnosis and therapy; some case scenarios still present a real challenge for the treating physicians. We report a case of a 50 year old male patient presenting with multi-territory cerebral infarctions due to a left ventricular mobile thrombus complicated with hemorrhagic transformation at the time of presentation. Gradual introduction of anticoagulation coupled with a multidisciplinary team approach advocating careful daily clinical assessment of the patient and regular echocardiographic and neuroimaging studies have resulted in a better management and achievement of therapeutic goals
