In this research, a gamma ray sensor (The Mole) was used to get the natural radionuclides concentration in situ in the surface layer of cultivated soils. For sand, silt and clay predictions, an adaptive neuro fuzzy inference system (ANFIS) was performed to predict such fractions (Sugeno model). The inputs to the system were Potassium (40K), Uranium (238U), Thorium (232Th) and Cesium (137Cs) concentrations. It is concluded that ANFIS structure is acceptable in the prediction of sand, silt and clay considering the studied inputs. Test results and predicted outcomes were compared and acceptable correlations were obtained.

圆盘犁的阻力和能耗需求被认为是与推土机功率正确匹配的重要因素。该研究通过与多元线性回归(MLR)模型的对比,测试了使用自适应神经模糊推理系统(ANFIS)来确定圆盘犁的阻力和能耗需求的可能性及其性能。通过实地试验和各种文献,共获得了133种数据模式。从这133个数据点中,随机选取了121个作为训练集,其余12个用于模型验证。输入变量为犁深度、犁速、土壤质地指数、初始土壤含水率、初始土壤体积密度、圆盘直径、圆盘角度和倾斜角度,输出变量为圆盘犁的阻力。ANFIS使用了四个从属函数:三角形从属函数、通用钟形从属函数、梯形从属函数和高斯曲线从属函数。对ANFIS和MLR建模结果的评估显示,三角形成员函数比其他函数执行效果更好。当将ANFIS模型预测与测量值进行比较时,阻力平均相对误差为-1.97%。ANFIS模型与其他方法进行比较的结果表明,圆盘犁的阻力和能耗需求可以得到令人满意的预估。

Background: Health information systems (HIS) play a major role in decision-making. The aim is to identify the components of computerized HIS and their relationship to administrative decisions at the main referral hospitals for Sana’a city. Method: This applied research is a descriptive, cross-sectional study in which the HIS of 7 hospitals affiliated with Sana’a city hospitals during “2017-2020”, was evaluated based on Self-administered questionnaires. Data were collected by using Self-administered questionnaires and analyzed in SPSS 16 by using descriptive statistics. Results: A total of 626 users (95.7%) had responded. 73%, 75%, 69%, 70%, 71% of users mentioned that resources were available, for physical, software, human, organizational, and decision computerized HIS, respectively. The study showed a strong relationship between computerized information systems with their physical, software, human and organizational components, and medical and administrative decisions. While the study showed the absence of a relationship between demographic factors and computerized information systems with their hardware, software, human and organizational components, medical and administrative decisions, except for gender with organizational components, age, qualification with hardware and software components, and years of experience with all study variables. Conclusion: The application of HIS at hospitals in decision-making has several challenges, including the lack of updating of hardware and software components Furthermore, the absence of specific, focusing on developing their technical staffs, and mobilizing financial resources to achieve implementation properly. Therefore, establishing the technical management with clear roles and tasks with multi-disciplinary, and increasing the support of the administrative leadership in the process of implementing HIS are recommended.

The past decade witnessed rapid development of constraint satisfaction technologies, where algorithms are now able to cope with larger and harder problems. However, owing to the fact that constraints are inherently declarative, attention is quickly turning toward developing high-level programming languages within which such problems can be modeled and also solved. Along these lines, this paper presents DEPICT, the language. Its use is illustrated through modeling a number of benchmark examples. The paper continues with a description of a prototype system within which such models may be interpreted. The paper concludes with a description of a sample run of this interpreter showing how a problem modeled as such is typically solved.

Background: Total quality management (TQM) plays a major role in quality health services improvement. The aims of the study are to identify the concepts of total quality management in health institutions to know the nature of the relationship between the application of TQM and improving the quality of health services in Sana’a Governorate. Method: This applied research is a descriptive cross-sectional study in which the TQM of 13 affiliated Sana’a Governorate hospitals during “2017-2020”, were evaluated based on self-administered questionnaires. Data were collected by questionnaires including demographical variables, TQM dimensions variables. Data were analyzed by using SPSS version 16. Results: A total of 281 users 98.6% had responded. The employee’s responses for sixth study dimensions were the top manager’s commitment (TMC) 80.46%, customers focusing CF 81.55%, continuous improvement (CI) 82.32%, training (T) 71.51%, and strategic planning of the quality (SPQ) 74.76%, health services quality improvement (HSQI) 74.25%. There is a strong relationship between TQM and HSQI. There is no relationship between demographic factors gender, profession, years of experience, except age with TMC, T, HSQI, qualification with the TMC, CI, T, HSQI and job with all study variables. Conclusion: The application of TQM at hospitals in quality of health services improvement has several challenges, lacking staff experience and lacking leadership support, weakness of the training, customers focusing, continuous improvement, and strategic planning of the quality. Therefore, benefiting from the experiences of leading hospitals in implementing total quality management programs by sending some cadres to these hospitals for training and gaining experience or by hosting experienced cadres to conduct training courses is recommended.

Background: Hypertension is associated with an increased risk of cardiovascular events, cardiovascular and all-cause mortality. However, the diagnostic ability of hypertension for the presence and severity of CAD (coronary artery disease) has not been elucidated. This study investigates the relationship between hypertension and CAD complexity using the SYNTAX score to determine hypertension’s roles in coronary heart disease progression. Method: This is a prospective study that includes consecutive 410 adult patients at mean age (61 ± 11 years) who are admitted to Cardiology Department and undergo invasive coronary angiography (CAG) where a significant coronary lesion (SCL) is defined as stenosis ≥50% in vessel diameter ≥ 1.5 mm. The SYNTAX scores were calculated using the SYNTAX score algorithm. Results: The mean rank of SYNTAX score was significantly higher among hypertension than non-hypertension (mean rank: 279, 184, p = 0.006) groups. SYNTAX score was positively correlated with age (r: 0.263, p significantly independent predictor of increase or decrease probability of falling in high syntax score group. Conclusion Hypertension affects the distribution of SYNTAX score among patients with and without hypertension, and the prevalence of significant coronary lesions was more frequent in hypertensive patients. Hypertension was not a predictor of significant or complex coronary artery lesion, but a
