A Mobile Ad-Hoc Routing Algorithm with Comparative Study of Earlier Proposed Algorithms

引用

International Journal of Communications, Network and System Sciences 2010年第3期3卷 289-293页

作者： Kumar Verma Pawan Gupta Tarun Rakesh nitin nitin nitin 不详

A mobile ad-hoc network is an autonomous collection of mobile nodes that communicate over bandwidth constrained wireless links. Due to nodal mobility, the network topology may change rapidly and unpredictably over time. The routing protocols meant for wired network cannot be used for mobile ad-hoc network because of mobility of network. A number of routing protocols like Destination-Sequenced Distance-Vector (DSDV), Ad-Hoc On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Temporally Ordered Routing Algorithm have been implemented. The ad-hoc routing protocols can be divided into two classes;Table-Driven and On-Demand. This paper examines two routing protocols for mobile ad-hoc networks—the Destination Sequenced Distance Vector (DSDV), the table-driven protocol and the Ad-Hoc On- Demand Distance Vector routing (AODV), an on-demand protocol and propose an algorithm that facilitates efficient routing of the packet and failure recovery

Weight loss endoscopy: Development, applications, and current status

引用

World Journal of Gastroenterology 2016年第31期22卷 7069-7079页

作者： nitin Kumar Bariatric Endoscopy Institute

Obesity and its comorbidities- including diabetes and obstructive sleep apnea- have taken a large and increasing toll on the United States and the rest of the world. The availability of commercial, clinical, and operative therapies for weight management have not been effective at a societal level. Endoscopic bariatric therapy is gaining acceptance as more effective than diet and lifestyle measures, and less invasive than bariatric surgery. Various endoscopic therapies are analogues of the restrictive or bypass components of bariatric surgery, utilizing gastric remodeling or intestinal anastomosis to achieve proven weight loss and metabolic benefits. Others, such as aspiration therapy, employnovel mechanisms of action. Intragastric balloons have recently been approved by the United States Food and Drug Administration, and a number of other technologies have completed large multicenter trials(such as AspireA ssist aspiration therapy and Primary Obesity Surgery Endolumenal). Endoscopic sleeve gastroplasty and transoral outlet reduction for endoscopic revision of gastric bypass have proven safe and effective in a number of studies. As devices are approved for use, data will continue to accumulate for safety, effectiveness, and cost effectiveness. Bariatric endoscopists should be prepared to appropriately target and apply various endoscopic bariatric therapies in the context of a comprehensive long-term weight management program.

Prevalence of excessive internet use and its correlation with associated psychopathology in 11th and 12th grade students

引用

General Psychiatry 2019年第2期32卷 84-91页

作者： nitin Kumar Arvind Kumar Subodh Kumar Mahto Manish Kandpal Smita Neelkanth Deshpande Parul Tanwar Department of Psychiatry Dr Ram Manohar Lohia Hospital and Post Graduate Institute of Medical Education and Research New Delhi India Department of Medicine Dr Ram Manohar Lohia Hospital and Post Graduate Institute of Medical Education and Research New Delhi India Vardhman Mahavir Medical College and Safdarjung Hospital New Delhi India

Background Globally, the number of internet users has crossed the three-billion mark, while in India users grew over 17% in the first 6 months of 2015 to 354 million. This study presented a background on internet use and the existence of excessive internet use. Aim To study the extent of internet use in 11th and 12th grade students and the psychopathology, if any, associated with excessive internet use. Methods 426 students who met the inclusion criteria were recruited from 11 th and 12th grade classes from Kendriya Vidyalaya, New Delhi, India, and were assessed by Young's Internet Addiction Test and the Strength and Difficulties Questionnaire. Results Among the 426 students, the mean internet addiction total score was 36.63 (20.78), which indicated mild level of internet addiction. 1.41%(six students) was diagnosed as excessive internet users, while 30.28% and 23.94% were classified as moderate and mild internet users, respectively. The prevalence of internet addiction between gender was 58.22% in males and 41.78% in females. While both positive (prosocial) and negative (hyperactivity, emotional, conduct and peer problem) impacts of internet use were reported by students, in the current study excessive use of internet had a negative impact on students' lives as compared with positive impact, which was statistically significant (p<0.0001). Conclusion Excessive internet use led to abnormal behaviours which cause negative consequences to users. Early diagnosis of risk factors related to excessive internet use, provides education about responsible use and supervision of students by family members.

Attitudes of Undergraduate Public Health and Health Science Students towards Interprofessional Education (IPE) at a California University

引用

Open Journal of Nursing 2022年第11期12卷 796-815页

作者： Charl Mattheus nitin Roy Department Public Health California State University Sacramento USA

Introduction: The study revealed that many healthcare professional students begin their academic studies with positive and high expectations towards interprofessional collaborative studies. Unfortunately, students lose interest if their initial expectations are not met with consistent opportunities to enhance their communication skills and better understand the different healthcare professions. The study aimed to explore health science and public health students’ attitudes toward IPE. The participants’ backgrounds and demographics were used as the variations for the study. Methods: A pre-post semi-quantitative anonymous survey was designed to assess health science and public health undergraduate students’ attitudes toward IPE. The reason for this design was to capture the participants’ attitudes toward IPE at the start of a semester when they had no academic exposure to IPE. Qualtrics was used to collect the research data. A valid and reliable scale was used to measure attitudes toward IPE. A post-survey was included to measure the participants’ change in attitude toward IPE during the semester. The goal was to measure the IPE curriculum effectiveness. There were 21 survey questions. The questions were divided into four validated subscales. The first seven questions (Questions 1 - 7) pertained to the participants’ demographics s, such as gender, age, race, ethnicity, major field of study, and prior education. Questions 8, 9, 16, & 20 were designed to determine how the participants perceived their roles and responsibilities in their future healthcare careers. Each IPE attitude question’s central tendency and demographic variations were measured. The correlation between demographics and IPE attitudes was measured. Results: The pre-survey had 192 participants, and the post-survey had 97 participants. The pre-survey had 87% of participants in the age group 17 - 25 years, while the post-survey had 82.5% in the same age group. Only 5.7% of the participants were 36 years o
