The ecosystem for digital payments in India has expanded quickly during the last decade. A synthesis of technical advancements and progressive governmental laws and regulations has fuelled this expansion. Particularly, the UPI system has assisted India in transitioning from a nation heavily reliant on cash for daily transactions to one with fewer cash transactions. The study attempted to determine how Financial Inclusion (FI) through a socio-techno-ecosystem impacts digital payment systems. FI involves ensuring financial services, products, and an adequate amount of credit without discrimination against the weaker section of society. The study has established that FI impacts the UPI. The finance infrastructure thus helps to develop an ecosystem where financial access and the awareness level help people to transit to new channels of payment. We have used secondary data of 27 banks for sixteen quarters and four years, i.e., for the financial years 2016-17 to 2019-20. It is observed from the current study that the offsite_ATM plays a significant role in the value creation of the UPI. Our study implies that it will help retailers, individuals, and business houses to use UPI platforms for swift payments without hassle. Also helpful for industries that are still not digitally disrupted and industry-specific UPI transactions.

For a minimally invasive approach to access the facial nerve, we designed an extended epitympanotomy via a transmastoid approach that has proven useful in cases of traumatic facial nerve palsy and pre-cholesteatoma. To evaluate the surgical exposure through an extended epitympanotomy, six patients with traumatic facial nerve palsy were enrolled in this study. The same surgical technique was used in all patients. Patients were assessed and the degree of facial nerve paralysis was determined prior to surgery, 1-week post-operatively, and 6-months post-operatively using the House-Brackmann grading system. In all cases, surgical exposure was adequate. All patients with traumatic facial nerve palsy were male and the age range was 13 to 83 years. In all cases, the location of the facial nerve damage was limited to the area between the first and second genu. Symptoms of all the patients improved by 6 months post-operation (p=0.024). There were no complications in any of the patients. Extended epitympanotomy is useful for safe, rapid surgical exposure of the attic area, sparing the patient post-operative dimpling, skin incision complications, and lengthy exposure to anesthesia. We suggest that surgery for patients with facial nerve palsy secondary to trauma be performed using this described technique.

After a disaster like the catastrophic earthquake, the government have to use rapid assessment of the condition (or damage) of bridges, buildings and other infrastructures is mandatory for rapid feedbacks, rescue and post-event management. Many domain schemes based on the measured vibration computations, including least squares estimation and neural fuzzy logic control, have been studied and found to be effective for online/offline monitoring of structural damage. Traditional strategies require all external stimulus data (input data) which have been measured available, but this may not be the generalized for all structures. In this article, a new method with unknown inputs (excitations) is provided to identify structural matrix such as stiffness, mass, damping and other nonlinear parts, unknown disturbances for example. An analytical solution is thus constructed and presented because the solution in the existing literature has not been available. The goals of this paper are towards access to adequate, safe and affordable housing and basic services, promotion of inclusive and sustainable urbanization and participation, implementation of sustainable and disaster-resilient buildings, sustainable human settlement planning and manage. Simulation results of linear and nonlinear structures show that the proposed method is able to identify structural parameters and their changes due to damage and unknown excitations. Therefore, the goal is believed to achieved in the near future by the ongoing development of AI and control theory.

This paper proposes a composite design of fuzzy adaptive control scheme based on TMD RC structural system and the gain of two-dimensional fuzzy control is controlled by parameters. Monitoring and learning in LMI then produces performance indicators with a weighting matrix as a function of cost. It allows to control the trade-off between the two efficiencies by adjusting the appropriate weighting matrix. The two-dimensional Boost control model is equivalent to the LMI-constrained multi-objective optimization problem under dual performance criteria. By using the proposed intelligent control model, the fuzzy nonlinear criterion is satisfied. Therefore, the data connection can be further extended. Evaluation of controller performance the proposed controller is compared with other control techniques. This ensures good performance of the control routines used for position and trajectory control in the presence of model uncertainties and external influences. Quantitative verification of the effectiveness of monitoring and control. The purpose of this article is to ensure access to adequate, safe and affordable housing and basic services. Therefore, it is assumed that this goal will be achieved in the near future through the continuous development of artificial intelligence and control theory.

This paper proposes a composite form of fuzzy adaptive control plan based on a robust observer. The fuzzy 2D control gains are regulated by the parameters in the LMIs. Then, control and learning performance indices with weight matrices are constructed as the cost functions, which allows the regulation of the trade-off between the two performance by setting appropriate weight matrices. The design of 2D control gains is equivalent to the LMIs-constrained multi-objective optimization problem under dual performance indices. By using this proposed smart tracking design via fuzzy nonlinear criterion, the data link can be further extended. To evaluate the performance of the controller, the proposed controller was compared with other control technologies. This ensures the execution of the control program used to track position and trajectory in the presence of great model uncertainty and external disturbances. The performance of monitoring and control is verified by quantitative analysis. The goals of this paper are towards access to adequate, safe and affordable housing and basic services, promotion of inclusive and sustainable urbanization and participation, implementation of sustainable and disaster-resilient buildings, sustainable human settlement planning and manage. Therefore, the goal is believed to achieved in the near future by the ongoing development of AI and control theory.

Many uncertainties affect the stability assessment of rock structures. Some of these factors significantly influence technology decisions. Some of these factors belong to the geological domain, and spatial uncertainty measurements are useful for structural stability analysis. This paper presents an integrated approach to study the stability of rock structures, including spatial factors. This study models two main components: discrete structures (fault zones) and well known geotechnical parameters (rock quality indicators). The geostatistical modeling criterion are used to quantify geographic uncertainty by producing simulated maps and RQD values for multiple equally likely error regions. Slope stability theorem would be demonstrated by modeling local failure zones and RQDs. The approach proided is validated and finally, the slope stability analysis method and fuzzy Laypunov criterion are applied to mining projects with limited measurement data. The goals of this paper are towards access to adequate, safe and affordable housing and basic services, promotion of inclusive and sustainable urbanization and participation, implementation of sustainable and disaster-resilient buildings, sustainable human settlement planning and manage. Simulation results of linear and nonlinear structures show that the proposed method is able to identify structural parameters and their changes due to damage and unknown excitations. Therefore, the goal is believed to achieved in the near future by the ongoing development of AI and fuzzy theory.

전통적으로 도서관에서는 이용자들이 필요로 하는 정보를 찾을 수 있도록 가르쳐주는 교육봉사를 해오고 있다. 그러나 현재 정보테크놀로지의 급격한 발달은 정보원의 형태, 이용자들의 정보이용 행태, 도서관에서 제공하는 정보봉사 등에 많은 변화를 낳고 있다. 인터넷정보원을 포함하여 전자정보원이 점점 많아지고 있으므로 이러한 형태의 정보원들을 이용자들이 제대로 이용할 수 있으려면 새로운 정보이용법을 익혀야 하고 이에 따라 도서관에서는 이전보다 더 큰 비중을 정보이용교육에 두어야 할 상황을 맞고 있다. 본 논문에서는 새로운 개념의 도서관에 알맞는 이용자교육방법으로 대학도서관의 웹사이트를 통해 이루어지는 원격정보이용교육에 대하여 조사하여 보았다. 한국 대학도서관의 웹사이트에는 주로 정보에 물리적 접근을 가능하게 하는 도서관의 위치, 정책, 운영, 소장 상황, 네트워크로 연결된 도서관 밖의 정보원 등을 설명하는 항목이 많은 반면, 미국이나 캐나다의 대학도서관의 경우에는 정보에 물리적 접근뿐만 아니라 한단계 더 나아가 원하는 정보 그 자체를 찾을 수 있도록 하는 즉, 정보에 지적 접근을 가능하게 해주는 항목이 많은 것으로 나타났다. 우리나라의 대학도서관에서도 학생들의 학업과 연구활동에 도움이 될 뿐만 아니라 일평생 살아가면서 필요한 정보를 스스로 찾아 쓸 수 있는 정보이용능력을 갖출 수 있도록 실질적인 정보이용교육이 이루어져야 할 것이며, 이를 위해 강력한 정보전달 수단으로 선호되어 점차 많이 보급되고 있는 도서관 웹사이트를 충분히 활용할 수 있어야 할 것이다.

Central venous catheter (CVC) for long-term venous access is indispensable for various reasons including hyperalimentation, frequent blood sampling, frequent IV drug use in pediatric patients. We report clinical experience of surgical neonates in whom CVC was inserted primarily via great saphenous vein into suprarenal inferior vena cava. From March 2004 to March 2006, we performed CVC insertion via saphenous vein - contralateral side to main wound - into suprarenal inferior vena cava in surgeries of neonates. 2.7Fr or 4.2Fr, single lumen, tunneled Broviac catheters (Bard Access system, Inc, Salt Lake City, Utah) were used. Skin exit site of tunneled catheter was located in ipsilateral flank area just below edge lower rib. At the end of the procedure, location of the catheter tip was confirmed by plain radiography of abdomen. We retrospectively reviewed the admission records of the patients including nursing staff charts. Nine (50.0 %) patients were male and nine (50.0%) were female. Median gestational age was 38 weeks (range, 29-42 weeks) and median birth weight was 3,105 gm (range, 1,040-3,720 gm). Median age at catheter insertion was 38.5 days (range, 1-236 days). The purpose of CVC insertion was short-and long-term hyperalimentation in nine (50.0 %) patients. CVC insertion was performed in operation room under general anesthesia in sixteen (88.9 %) patients (in these cases, CVC insertion was performed just prior to concurrent operation) and neonatal intensive care unit (NICU) under local anesthesia with adequate sedation in two (11.2%). During the admission period (total catheter-indwelling time: 553 days), CVC functioned well without any significant side effects. Transient swelling of the ipsilateral leg (n=1, 5.6 %) and transient migration of catheter tip (n=1, 5.6 %) were noted, which did not affect function of the indwelled CVC. Mean catheter-indwelling time was 30.7days (range, 3-72 days). All catheters were removed electively except two mortality case. Complications, such as thrombosis, infection, kinking or extravasation of drugs, were not observed in our study period. Tunneled trans-great saphenous vein inferior vena cava catheters are not only comparable to cervical CVCs in terms of function and complication rates, but also very beneficial in selected patients, especially those in whom cervical approach is technically impossible or contraindicated.
