Arsenic poisoning in ground water is one of the most sensitive environmental pollutant causing serious pollution all over the world. Chronic arsenic exposure through drinking water to humans leads to major public health related issues. There have been very meagre studies which reported that, the plant constituents proved to exhibit protective effect from arsenicosis. Therefore, the present study aims to evaluate the protective efficacy of Coriandrum sativum seeds extract against sodium arsenite induced toxicity in Swiss albino mice. In the present study twenty-four male healthy Swiss albino mice (30 ± 5 g) were divided into four groups (n = 6), where the control group received normal diet and water; group II and group III treated with sodium arsenite (2 mg per kg body weight per day) for 2 and 4 weeks respectively. The group IV mice were administered with C.sativum seeds extract at the dose of 150 mg per kg body weight per day for 4 weeks upon sodium arsenite pretreated (2 mg/kg body weight for 4 weeks per day) mice. After the complete dose duration, all the treatment group animals were sacrificed same day for haematological, biochemical and histopathological study. In the arsenic treated mice, there were significant (p < 0.0001) changes in the serum levels of ALT, AST, ALP, urea, uric acid and creatinine as well as in the haematological parameters. In contrast, after the administration with C.sativum seeds extract upon arsenic pretreated mice, there was significant (p < 0.0001) improvement observed in the hepatic and renal biomarker parameters as well as haematological variables. In the arsenic intoxicated mice, after administration with C.sativum seeds extract there was significant (p < 0.0001) reduction in the arsenic concentration in blood, liver and kidney tissues as well as in the serum LPO levels. Furthermore, the histopathological study showed that, C.sativum seeds extract administrated group of mice significantly restored the liver and kidney at cellular level against arsenic induced toxicity. The entire study concludes that C.sativum seeds extract possesses the ameliorative effect against arsenic induced liver and kidney intoxication.

India’s Policy towards the North Korean Nuclear Weapons Program

Ranjit Kumar Dhawan 통일연구원 2020 International journal of korean unification studie Vol.29 No.1

After the end of the Cold War, which marked the end of ideological rivalry between the two superpowers of the world, it was often thought that the threats of nuclear warfare had declined. However, the South Asian region and the Korean Peninsula in Northeast Asia have emerged as the new nuclear hotspots. The denuclearization of the Korean Peninsula is being regarded as a necessary step towards building peace in the region. Although the conflict on the Korean Peninsula does not affect India directly, the exchange of nuclear and missile technology between Pakistan and North Korea has been an issue of deep concern to New Delhi. India’s stand on the North Korean nuclear weapons issue has evolved over the years and in 2017 the Indian Government came out with official notifications which have imposed severe restrictions on any cooperation with North Korea, except for providing food and medical assistance to this isolated state. This article aims to explain India’s policy towards the North Korean nuclear weapons program.

Mahatma Gandhi’s Swadeshi and KimIl-sung’s Juche Ideas in the Era of Globalization: A Comparative Analysis

Ranjit Kumar Dhawan 통일연구원 2023 International journal of korean unification studie Vol.32 No.1

The advent ofimperialisminthe modernperiod triggered a wave of self-reliance movements in colonized countries. In India, Mahatma Gandhi promoted the idea of Swadeshi to boycott foreign-made products and supported the growth of indigenous industries in order to gain national independence. In North Korea, Kim Il-sung made the Juche idea a guiding philosophy of the state for autonomous economic development and make the country self-reliant. Although the ideas of Swadeshi and Juche share several similarities, there are also major differences between these two views on self-reliance. Ironically, the overemphasis on self-reliance inthe realm of economic development in both India and North Korea led to poverty and backwardness in these two nations. However, compared to North Korea, India adopted economic liberalization measures in the post-Cold War period, but the Indian Government still aims for achieving self-reliance. Therefore, this article is aneffort to compare andexplainthe ideas of Swadeshi and Juche in the era of globalization and argues that the North Korean regime may have to implement some serious economic reforms for the survival of the country in the coming times

South Korea’s Policy towards China’s “Belt and Road Initiative”: Implications for India

( Ranjit Kumar Dhawan ) 한국국방연구원 2020 The Korean Journal of Defense Analysis Vol.32 No.3

China’s “Belt and Road Initiative” (BRI) is being projected as one of the biggest infrastructure and connectivity projects of the 21st century. This Chinese mega project has evoked varied responses from the Asian nations. South Korea (hereafter Korea) which is the fourth biggest economy in Asia and an important trade partner of India has been supportive of the BRI, as this strategy is compatible with Seoul’s own vision of increased connectivity with the Eurasian market, capital, labor and resources, and is conducive to the promotion of Korean national reunification. On the other hand, India has been opposed to the BRI as it overlooks New Delhi’s sovereignty concerns and serves China’s geopolitical interests. Also, India has been supporting the “Indo-Pacific strategy” along with the United States, Japan and Australia to counter China’s rising hegemony in the region. As a result, Korea and India have different views on the BRI. This article aims to conduct an analysis of Korea’s policy towards China’s BRI which could have detrimental implications for India and argues that there is a need to take some serious measures to improve Korea-India relations in the coming times.

A Novel Approach for Task Scheduling in Parallel Computing using Priority Attributes

Ranjit Rajak,Shobhit Gupta,Girish Kumar Singh,Sanjay Jain 한국산학기술학회 2015 SmartCR Vol.5 No.4

The major objective of any task-scheduling algorithm in parallel computing is to minimize the overall scheduling length. In this research paper, we present a task-scheduling algorithm in parallel computing called the Critical Path and b-level Based Task Scheduling algorithm. This algorithm is based on a new attribute, which is called the CPB attribute, which is based on two well-known priority attributes: Critical Path and B-Level. This algorithm uses entry tasks as duplicates in all of the available processors. The major objective of any task-scheduling algorithm is to minimize the overall scheduling length. Here, an application program in task scheduling is represented by a directed acyclic graph. We consider all processors to be homogenous in nature and fully connected. The Critical Path and b-level Based Task Scheduling algorithm gives a minimum scheduling length when compared to heuristic task-scheduling algorithms like the HLFET, MCP, DLS, and ETF. We have also done an analysis of the proposed algorithm and heuristic algorithms based on other priority attributes: Speedup, Efficiency, Scheduling Length Ratio, Load Balancing, and Cost.

Determinants of Satisfaction in the Usage of Healthcare Information Systems by Hospital Workers in Hyderabad, India: Neural Network and SEM Approach

Surya Neeragatti,Ranjit Kumar Dehury 한국경영정보학회 2023 Asia Pacific Journal of Information Systems Vol.33 No.4

This study focuses on the adoption of Healthcare Information System (HIS) in India’s healthcare services, which has led to an increased use of HIS software for managing patient information in hospitals. The study aims to evaluate the factors that influence hospital workers’ satisfaction with HIS usage and its impact on their intention to continue in the use of HIS. Primary data was collected through a survey questionnaire from 265 hospital workers. A new framework was developed, and Structural Equation Modeling (SEM) was used for analysis. Sensitivity analysis was also conducted on demographic data using an Artificial Neural Network (ANN) approach. The results indicated that all hypotheses were significant (p < 0.05). Effort expectancy was the most significant factor influencing hospital workers’ satisfaction (p < 0.01). Sensitivity analysis showed that education (Model-A) and experience in use of HIS (Model-B) were the most important factors. The study contributes by proposing a new theoretical framework and extending the previous research on HIS usage satisfaction. Overall, the study highlights the importance of easiness and usefulness in predicting HIS usage satisfaction.

Shobhit Gupta,Ranjit Rajak,Girish Kumar Singh,Sanjay Jain 한국산학기술학회 2015 SmartCR Vol.5 No.1

Task scheduling is a well-known NP-complete problem. It is one of the research areas in parallel computing. Task scheduling consists of an application program and a set of processors for allocating the various tasks. An application program is represented using a directed acyclic graph(DAG) and a set of processors that are homogenous and fully connected. In this paper, we study different task duplication-based (TDB) scheduling algorithms and their priority attributes and time complexity. Also, we will discuss different types of performance metrics in task scheduling algorithms. These performance metrics help to analyze different task scheduling algorithms.

Arbitrary Processor Network Scheduling Algorithms in Parallel Computing

Shobhit Gupta,Ranjit Rajak,Girish Kumar Singh,Sanjay Jain 한국산학기술학회 2015 SmartCR Vol.5 No.3

Task scheduling in parallel computing is represented by a directed acyclic graph, and it is called multiprocessor task scheduling. The primary objective of task scheduling algorithm is to minimize the total execution time i.e. scheduling length. There are various types of task scheduling algorithms: Bound Number of Processor Scheduling, and Arbitrary Processor Network Scheduling Algorithms. Bound Number of Processor Scheduling algorithms are used for limited number of processors; since it does not use task duplication, link contention, and routing strategy for communication. But Arbitrary Processor Network scheduling algorithms are considered for link contention routing strategy in communication. It uses arbitrary network topology. In this paper, we have studied different Arbitrary Processor Network scheduling algorithms: Mapping Heuristic, Dynamic Level Scheduling, Bottom Up, and Bubble Scheduling and Allocation. The primary objective of this survey paper is to explain various Arbitrary Processor Network scheduling algorithms and their functionality, priority attributes, and time complexity. The performance metrics can also be used for comparison of different Arbitrary Processor Network scheduling algorithms.

Pandemic induced lockdown as a boon to the Environment: trends in air pollution concentration across India

Gautam Alok Sagar,Sanjeev Kumar,Sneha Gautam,Aryan Anand,Ranjit Kumar,Abhishek Joshi,Kuldeep Bauddh,Karan Singh 한국기상학회 2021 Asia-Pacific Journal of Atmospheric Sciences Vol.57 No.4

The present paper designed to understand the variations in the atmospheric pollutants viz. PM10, PM2.5, SO2, NO2, and CO during the COVID-19 pandemic over eight most polluted Indian cities (Mumbai, Delhi, Bangalore, Hyderabad, Lucknow, Chandigarh, Kolkata, and Ahmedabad). A significant reduction in the PM2.5 (63%), PM10 (56%), NO2 (50%), SO2 (9%), and CO (59%) were observed over Major Dhyan Chand Stadium. At Chhatrapati Shivaji International Airport, a decline of 44% in PM2.5 and 50% in PM10 was seen just a week during the initial phase of the lockdown. Gaseous pollutants (NO2, SO2 & CO) dropped up-to 36, 16, and 41%, respectively. The Air Quality Index (AQI) shows a dramatic change from 7% to 67% during observation at Chandigarh and Ballygunge during the inspection. Whereas, Ahmedabad, Worli, Income Tax Office, Talkatora, Lalbagh, and Ballygaunge have showed a significant change in AQI from 25.76% to 68.55%. However, Zoo Park, CST, Central School, and Victoria show relatively low variation in AQI in the range of 3.0% to 14.50% as compare to 2019 after lockdown. Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) analysis suggested that long range transportation of pollutants were also a part and parcel contributing to changes in AQI which were majorly coming from the regions of Iran, Afghanistan, Saudi Arabia, as well as a regional grant from Indian Gangatic plains and Delhi Non-capital region.
