Marine Plastic Pollution in Indo-Pacific: ‘Together’ for Better ‘Future’
S. Sivakumar,Prakash Sharma 한국법제연구원 2021 KLRI journal of law and legislation Vol.11 No.2
According to a 2020 study titled “Changing Sails: Accelerating Regional Actions for Sustainable Oceans in Asia and the Pacific,” the Indo-Pacific region produces nearly half, together with consuming “more than one-third of the total world’s plastic.” It further reveals that owing to the inbuilt constraints in terms of methodology, coupled with inconvenient statistical systems, there remains serious concern for proper data procurement. Further, due to unchecked and uncontrolled human activities, the salubrity of oceans and seas is now “being pushed to a tipping point” and without proper data, the world appears to “swim in the dark.” The picture appears more horrific with COVID-19, particularly with additional reliance placed on the use of plastic. With plenty of challenges there are calls for review of goods production cycles through efficient strategies. In this perspective, we argue, first, no matter where we live, the ocean influences all of us. Therefore, the future we want demand easing of the complex relation between human and oceans, especially in the light of limited Earth’s ability to back rampant human desires. Secondly, the inherently wasteful linear plastic economy has resulted in overconsumption, destructive practices, acidification and subsidies that have caused irreplaceable damage to the state of oceans. As a result, the article maintains that (a) there is a weak legal and institutional framework, and (b) interaction between ocean and human activities, calls for better data demands. Further, the Sustainable Development Goal No. 14 strives towards promoting the health and sustainability of oceans. This holds a great importance, especially for the viable development of the Asia and the Pacific region which inhibits richest pool of the living natural resources in the world. The article suggests that both India and South Korea can take the lead and build up a mechanism of strengthening and promoting scientific know-how, develop research skills and share marine technology.

Urbanization and industrialization have significantly increased the amount of solid waste produced in recent decades, posing considerable disposal problems and environmental burdens. The practice of waste utilization in concrete has gained popularity among construction practitioners and researchers for the efficient use of resources and the transition to the circular economy in construction. This study employed Lytag aggregate, an environmentally friendly pulverized fuel ash-based lightweight aggregate, as a substitute for natural coarse aggregate. At the same time, fly ash, an industrial by-product, was used as a partial substitute for cement. Concrete mix M20 was experimented with using fly ash and Lytag lightweight aggregate. The percentages of fly ash that make up the replacements were 5%, 10%, 15%, 20%, and 25%. The Compressive Strength (CS), Split Tensile Strength (STS), and deflection were discovered at these percentages after 56 days of testing. The concrete cube, cylinder, and beam specimens were examined in the explorations, as mentioned earlier. The results indicate that a 10% substitution of cement with fly ash and a replacement of coarse aggregate with Lytag lightweight aggregate produced concrete that performed well in terms of mechanical properties and deflection. The cementitious composites have varying characteristics as the environment changes. Therefore, understanding their mechanical properties are crucial for safety reasons. CS, STS, and deflection are the essential property of concrete. Machine learning (ML) approaches have been necessary to predict the CS of concrete. The Artificial Fish Swarm Optimization (AFSO), Particle Swarm Optimization (PSO), and Harmony Search (HS) algorithms were investigated for the prediction of outcomes. This work deftly explains the tremendous AFSO technique, which achieves the precise ideal values of the weights in the model to crown the mathematical modeling technique. This has been proved by the minimum, maximum, and sample median, and the first and third quartiles were used as the basis for a boxplot through the standardized method of showing the dataset. It graphically displays the quantitative value distribution of a field. The correlation matrix and confidence interval were represented graphically using the corrupt method.

Insolvency and Bankruptcy Framework:India Perspective
S. Sivakumar 한국법제연구원 2019 KLRI journal of law and legislation Vol.9 No.2
Insolvency or Bankruptcy is a state where an individual or an entity is unable to pay its debts as and when they fall due or when the realizable value of assets are insufficient to meet the liabilities. A strong insolvency and bankruptcy regime should provide for resolution/reorganization to enable the entity to become financially sound in a time-bound manner. If this is not possible, it should ensure that a quick liquidation/bankruptcy mechanism is put in place to enable take over and disposal of assets and make payment of the proceeds to creditors. India has enacted comprehensive legislation called Insolvency and Bankruptcy Code 2016 (IBC) for dealing with insolvency resolution and liquidation of corporate entities and insolvency resolution and bankruptcy for non-corporate entities like individuals and firms. A separate regulatory body, the Insolvency and Bankruptcy Board of India, has been set up for overseeing the process and also to regulate the entities involved in the process, i.e., insolvency professional agencies and professionals, information utilities, registered valuers, etc. Special courts, i.e., National Company Law Tribunal and National Company Law Appellate Tribunal, have been set up for handling matters relating to Insolvency and Bankruptcy of corporates. While the corporate insolvency process has been implemented, the provisions of the Code relating to individuals and firms would be implemented in a phased manner. With the enactment and implementation of IBC, the necessary infrastructure – legal, regulatory, institutional and capacity building – for handling insolvency and bankruptcy in the country under single legislation has been put in place. This important reform has helped India leap significantly in the ranking in World Bank’s Ease of Doing Business and resolving insolvency. IBC has shown promising results in facilitating the resolution/reorganization of companies in distress and recovery of money from the sale of business and take over and sale of their assets. Simultaneously, there are several concerns in effective resolution and liquidation making it necessary for further reforms to make the law more effective. The paper discusses the historical perspective, key aspects of Insolvency and Bankruptcy Code of India, its performance and the progress made, issues faced and the future agenda, including suggestions to improve the system.

Decentralization has been a significant trend in governance and economic development in many countries over the past few decades. It involves the transfer of decision-making power from central authorities to local governments, allowing for greater participation and involvement of citizens in the democratic process. In response to the demands of ethnic and national diversity, federalism required a unique and robust institutional design. Decentralization became an institutional design that catered for a distinct way of conceptualizing the sharing of powers. However, there is a lack of systematic research on the impact of decentralization on economic growth and democratic governance. The issue of local autonomy wherein the local governments can act independently requires answering multifaceted questions about whether decentralization will yield the desired results. The article explores the two imperative aspects of decentralization. It first explores the meaning and definition of decentralization and its desired objective. Both India and the Republic of Korea (ROK) provide insights into these questions and highlight the stages of democratization at various governance levels. While doing so, the variations in the extent and effectiveness of decentralization reforms in these two countries due to differences in their political, economic, and social contexts are kept in mind, as it seeks to explore the impact of decentralization in India and South Korea, two countries that have undergone significant decentralization reforms.

Soluble cutting fluids (SCFs) have been used in metal machining processes to improve the quality of metal processing equipment and products in modern society. Because the characteristics among metal machining processes differ, various types of cutting fluids are manufactured to enhance the cutting efficiency of different metals. Although SCFs are useful and essential materials, particular treatment is required attributable to the high concentration of nitrogen materials and chemical oxygen demand (COD). In this study, the removal efficiency of total nitrogen (T-N) contained in SCFs was analyzed using electrochemical treatment. The electrode was made of 316 stainless steel, which had been perforated to prevent an imbalanced sample concentration in the reactor. Cathodic and anodic electrodes were alternately inserted into an acrylic reactor. The removal efficiency of T-N in SCFs using 40 A/m2, 60 A/m2, and 80 A/m2 current density, was 48.2%, 61.5% and 69.3%, respectively. The removal efficiency of T-N in SCFs with the addition of 0, 5 mM, and 10 mM NaCl was 69.3%, 74.6%, 77.6%, respectively.
