Quantifying Stream Return Flow of Agricultural Water Using SWAT-MODFLOW-PADDY Model in Korean Paddy Fields

In many countries, the irrigation return flow focuses only on surface and subsurface flows. In contrast, South Korea adopts a broader approach, defining the stream return flow as encompassing both quick and delayed return flows, which include subsurface flow and deep percolation. This study proposes redefining the stream return flow to include only the subsurface return flow, excluding deep percolation. We quantified the subsurface return flow and deep percolation using the SWAT-MODFLOW-PADDY (SMP) model, confirming that the current definition overestimated the stream return flow in Korea. The results show that the subsurface return flow accounted for 20% to 60% of the total infiltration, with the remaining 40% to 80% contributing to deep percolation and groundwater recharge. These findings reveal significant regional variations in the subsurface return flow rates, underscoring the limitations of applying a uniform stream return flow rate. We propose that allocated management water, subsurface, and quick return flows should be the primary components considered in stream return flow calculations, as the current practice of including delayed return flow leads to overestimated results. This study highlights the challenges in monitoring the subsurface return flow and the need for region-specific models that account for local conditions such as topography, soil characteristics, and climate. Our findings provide a more accurate approach to estimating the subsurface return flow, which is crucial for improving the efficiency and sustainability of agricultural water management in Korea.

Application of disease activity index in rheumatoid arthritis management in Korea.

Effective management of rheumatoid arthritis (RA) necessitates the accurate measurement of disease activity using a treat-to-target strategy established as a cornerstone approach. Disease activity assessment tools such as the Disease Activity Score in 28 joints (DAS28), Simplified Disease Activity Index, Clinical Disease Activity Index, and Routine Assessment of Patient Index Data 3 have been internationally validated and recognised. In Korea, the government initiated a quality assessment program mandating routine measurement of DAS28 to ensure high-quality RA management. However, whether the DAS28 is the most suitable disease activity measurement tool in the Korean clinical environment is a topic worth considering. In this review, we comprehensively examined disease activity measurement tools and their performance in the Korean context. We also propose a new strategy for measuring RA disease activity, tailored to the different situations encountered by physicians in routine clinical practice. This review may contribute to the improvement of the quality of care for patients with RA in Korea.

A Single Center Experience of Pulmonary Arterial Hypertension Management in Korea: A 25-Year Comparative Analysis Following the Introduction of Targeted Therapy.

The transformation of pulmonary arterial hypertension (PAH) treatment in Korea, ushered by targeted therapy's advent, prompted our analysis of baseline attributes, treatment trends, and survival shifts within our single-center registry. We examined 230 patients (72.6% female, mean age 40.6±17.4 years) diagnosed and/or treated between 1980 and 2021 in our PAH clinic. Given targeted therapy's introduction and active use since 2007, we compared diagnostic classification, demographics, and treatment patterns at that juncture. Survival analysis encompassed PAH types and the overall population. For historical survival comparison, 50 non-registry patients were retrospectively added, and age-sex matching enabled pooled analysis. Congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH) constituted the largest subset (43.0%), trailed by connective tissue disease-associated PAH (CTD-PAH, 29.6%) and idiopathic PAH (IPAH, 19.1%). Post-2007, CTD-PAH proportions surged, notably with an elevated initiation rate of targeted therapy (95.4%). Overall survival rates at 1, 5, and 10 years stood at 91.3%, 77.4%, and 65.8%, respectively, with CHD-PAH exhibiting superior survival to idiopathic or CTD-PAH. Age-sex matching analysis indicated survival disparities between those starting immediate targeted therapy vs. conservative treatment upon diagnosis, especially driven by IPAH. In the post-introduction of the targeted therapy era, patients with PAH promptly started treatment right away, and higher survival rates of patients who started initial PAH-targeted therapy were demonstrated. The transition towards early treatment initiation might have likely contributed to the elevated survival rates observed in Korea's PAH patient cohort.

Unlocking the potential of green human resource management in Korea: a comprehensive review

ABSTRACT This study provides a comprehensive review of the Green Human Resource Management (GHRM) literature, emphasizing recent developments in the Korean business sphere, where sustainability has become increasingly significant. The study also aims to mitigate the limited focus on GHRM in Korea by analysing recent practices and initiatives, as demonstrated through case studies from six major Korean firms. We find that GHRM in Korea serves as a strategic response to intensifying institutional pressures, such as regulatory changes and stakeholder expectations, facilitating firms’ navigation through the complex landscape of Environmental, Social and Governance (ESG) management in alignment with societal norms and expectations. In particular, GHRM in Korea is aligned with performance-based HR models, predominantly focusing on enhancing both environmental responsibility and business performance through strategic goal setting and high-powered ESG-linked performance incentives. This integration facilitates the quantitative management of environmental and social impacts, boosting sustainability alongside business performance.

Assessing the Feasibility of Biorefineries for a Sustainable Citrus Waste Management in Korea.

Citrus fruits are one of the most widely used fruits around the world and are used as raw fruits, but are also processed into products such as beverages, and large amounts of by-products and waste are generated in this process. Globally, disposal of citrus waste (CW) through simple landfilling or ocean dumping can result in soil and groundwater contamination, which can negatively impact ecosystem health. The case of Korea is not much different in that these wastes are simply buried or recycled wastes are used as livestock feed additives. However, there are many reports that CW, which is a waste, has high potential to produce a variety of products that can minimize environmental load and increase added value through appropriate waste management. In this study, we aim to explore the latest developments in the evaluation and valorization of the growing CW green technologies in an effort to efficiently and environmentally transform these CW for resource recovery, sustainability, and economic benefits. Recent research strategies on integrated biorefinery approaches have confirmed that CW can be converted into various bioproducts such as enzymes, biofuels and biopolymers, further contributing to energy security. It was found that more efforts are needed to scale up green recovery technologies and achieve diverse product profiling to achieve zero waste levels and industrial viability.

Evaluation of the Characteristics of Pollutant Discharge in Tomato Hydroponic Wastewater (HWW) for Sustainable Water Management in Korea

In South Korea, the use of hydroponic cultivation has been on the rise. However, this system produces a large amount of wastewater. In this study, the amount of wastewater generated by hydroponic tomato cultivation is identified, and a management plan is proposed. Based on the analysis of 103 tomato HWW samples, it was found that the electrical conductivity (EC) was 4.25 ± 1.01 dS/m, the nitrogen (N) content was 411.21 ± 122.64 mg/L, and the phosphorus (P) content was 47.74 mg/L, which caused eutrophication. Therefore, agricultural reuse and HWW treatment were proposed. Regarding the annual HWW load, 1 ha of hydroponics discharges 964.26 kg/ha of N, 111.95 of P, 937.46 of K, 795.14 of Ca, 313.83 of Mg, and 405.40 of S. The trace elements were heavy metals, which were calculated as Fe—4.03, Mn—0.77, Zn—1.08, B—2.25, Cu—0.38, and Mo—0.05 kg/ha. Since wastewater is a national source of drinking water, it needs to be collected and treated. Inter-item correlation analysis showed that most of the fertilizer components were correlated with the EC concentrations. This study can be used to determine the concentrations required for agricultural reuse and to determine the treatment capacity in HWW management.

The Status of Cord Blood Banks and Their Management in Korea

Korean cord blood banks (CBBs) are stagnant, so we explore how to overcome this. For eligible CB units (CBUs), CBBs need to strengthen quality control and conduct innovative clinical trials to facilitate cord blood transplantation (CBT). For ineligible CBUs, it is necessary to promote domestic research and remove unnecessary regulations regarding foreign research. Establishing a Korean cord blood network will facilitate communication among related groups. Now cellular immunotherapy is the new horizon for CBBs. Thus, CBBs will shift the paradigm of our mission in diverse ways.

Comparative Study of Legal Responsibility of B3 Waste Producers in Medical B3 Waste Management Crowded in Hospitals Under the Law Indonesia and South Korean Law

This study uses a normative legal research type, while the nature of the research used in this writing is descriptive, analytical to analyze and describe the comparative legal responsibility of B3 waste producers in solid medical B3 waste management in hospitals in Indonesia and South Korea. The regulation of the legal responsibility of B3 waste producers in the management of solid medical B3 waste in hospitals in Indonesia is regulated in Law No. 32 of 2009 which states that everyone who produces B3 waste is obliged to manage the waste they produce, including in this case health service facilities that produce medical B3 waste. Medical B3 waste management activities include Reduction and sorting, Storage, Transportation, Processing, Burial and/or Landfill activities of B3 Waste. The management of solid medical B3 waste in hospitals in South Korea was regulated by the Medical Law under the Ministry of Health and Welfare until 1999. The Ministry of Environment announced several regulations for the definition, segregation, packaging, tracking, and final disposal of medical waste. Medical B3 waste management in Korea and Indonesia has similarities in legal, technical and operational aspects. This is one of them because Korea and Indonesia adhere to the same legal system, namely the continental European legal system (civil law).

결합건축제도와 용적률 거래제의 관계에 관한 연구

Under the Building Act, the “combined building system” refers to the construction of a building by integrating the area ratio of a building to two or more sites without applying it to each individual site. All buildings in Korea are subject to floor area ratios under the Building Act. However, the “combined building system” is a system that eases the existing floor area ratio standard because it does not apply the floor area ratio under Article 56 of the Building Act to each individual site, but integrates it to two or more sites.
 The ‘combined building system’ is sometimes referred to as the ‘capacity ratio transaction system’ that is distinct from the ‘development rights transfer system’ of the United States in the sense of transferring unused volumes in Korea. The transfer (transaction) of a volume means that a volume that is permitted but not in use for an existing building can be transferred to an adjacent or nearby land for use. Prior to that, the transfer of floor area ratio in Korea was an unfamiliar concept, and it was relatively recent to be introduced through the Building Act, but overseas such as the United States and Japan have already introduced and implemented a system to transfer and trade unused volumes, and as many cases have been accumulated, the structure has been used in various ways to go through continuous maintenance.
 Efforts should be made to prepare and materialize practical policy alternatives in order for important policy directions to be pursued nationally, such as green growth and the realization of a fair society, to not stop at empty slogans. The floor area ratio transaction system and the purchase system can be said to be a system that lays the foundation for advancing the framework of the land market and national land management in Korea.

A Comparative Analysis of Epidemics Management in Korea: From the Unification of Shilla to Modern COVID-19

Epidemics have been a major threat to human health throughout history. The development of modern medicine has led to a decline in deaths from infectious diseases, but they remain a major public health concern. The COVID-19 pandemic has highlighted the importance of effective infectious disease management. This study examines the management of infectious diseases in Korea. The study finds many similarities between how infectious diseases were managed in the past and how they are managed today. However, the study also finds some critical differences between how contagious diseases were managed in the past and how they are managed today. The study concludes by arguing that studying the history of infectious diseases can help us better understand and manage infectious diseases in the future.

Impacts of COVID-19 pandemic on corporate cash holdings: Evidence from Korea

We examine how corporate cash management in Korea has evolved during the COVID-19 crisis, focusing on the interaction between COVID-19-related uncertainty and financing frictions. Compared with the 2008 global financial crisis, massive expansionary financial policy measures have resulted in low external financing costs shortly after the early negative shocks to external financing. This provides a unique opportunity to investigate the separate effects of uncertainty and financing frictions on corporate cash holdings. Consistent with the precautionary motive for cash holdings, we find that firms reserve more cash in 2020 in response to the increased uncertainty; this is especially the case if they are negatively affected by the COVID-19 crisis and financially constrained. However, unaffected firms with better access to financial markets and internal capital markets also increase their cash holdings. The COVID-19 pandemic does not systematically change corporate cash management policies. In 2021, firms decrease their cash holdings as uncertainty declines. Overall, our evidence implies that uncertainty is the primary determinant of corporate cash management decisions, whereas financing frictions play a secondary role. We discuss the policy implications of the amplified inequality between financially constrained and unconstrained firms resulting from massive expansionary financial policy measures.

Development and Utilization of Drug Lifecycle Data in the United States, Japan, and Europe

Objectives: With the growing interest in big data, regulatory agencies in United States, Japan, and Europe are showing active movements to use RWD and RWE to manage drug safety and development activation. Along with the global movements, it is necessary to establish a basic system for utilizing RWD based drug lifecycle data for drug safety management in Korea. The purpose of this study is to review and find implication of the collection and utilization of drug lifecycle data in the U.S., Japan, and Europe.Methods: In order to investigate the current status and contents of each country’s system, we searched the websites of each country’s regulatory agency and related agencies, and collected and investigated related laws, papers, and reports. We compared and analyzed focusing on solving regulatory problems that may occur in the drug lifecycle or exploring the safety and potential effects of drugs in drug lifecycle phases.Results: Based on FDA Sentinel 5-year plan and MID-NET, the U.S. and Japan are accelerating the generation of real data and real evidence for regulatory decision-making in post-marketing safety management. In Europe, various clinical field-specific projects have been undertaken to assess the effectiveness and safety of drugs due to disease. Various research cases using drug lifecycle data collected from drug safety management systems in each country have been represented.Conclusions: By identifying drug safety management systems and cases of drug lifecycle data utilization in various countries, we expect to serve as a stepping stone for discussions on the direction and utilization plan to efficiently develop drug safety management systems in Korea.

Global Radioactive Waste Disposal Trends and Prospects

Nuclear power generation, which began in the Soviet Union in June 1954, has now become a main source of electrical energy in 33 countries around the world. However, radioactive waste and its safety have always been at the center of controversy, and even after 70 years, there is no official regulation on the disposal of radioactive waste under international law. In this review, the policies and current status of radioactive waste disposal in major countries around the world, including Korea, are investigated. Based on this, the direction for radioactive waste management in Korea was presented. Currently, radioactive waste is disposed of in two ways. Finland, Sweden, and France are conducting deep permanent disposal according to the recommendation of the International Atomic Energy Agency, and Japan, the United Kingdom, and India are promoting reprocessing of spent nuclear fuel to reduce waste and the volume of the repository. Korea has been temporarily storing radioactive waste at the site of the power plant since the completion of Kori Unit 1 in 1978, but it is expected that the capacity of the temporary storage facility will reach its limit in 2031. Accordingly, the securing of a permanent disposal site and the development of reprocessing technology are being studied together, but no tangible results have been achieved so far. Korea's radioactive waste disposal has problems such as a small land area, institutional difficulties in developing reprocessing technology, frequent policy changes, ignorance and indifference, and lack of smooth communication. Although public concern about nuclear power generation has increased due to the Fukushima disaster, not many people are interested in spent nuclear fuel. Within the framework of reprocessing and permanent disposal, Korea should refrain from frequent policy changes that can confuse public opinion and research and development, and come up with a long-term realistic policy.
