MANAGEMENT OF AVASCULAR NECROSIS THROUGH PANCHAKARMA -A CASE STUDY

Avascular necrosis of the femoral head (AVNF) is an increasingly common cause of musculoskeletal disability. It is a progressive pathological process, resulting in the death of bone cells of the femur head due to disruption of blood supply to the proximal femur. However, the healing process is usually effective in AVN, and the bone tissue breaks down faster than the body can repair. All the treatment procedures are cost worthy, and the prognosis is poor. Management of AVNF aims to prevent structural deformity, regulate functional activity, and relieve pain. There is no direct diagnostic correlation to AVNF in Ayurvedic classics; however, signs and symptoms of AVNF are nearer to Vatarakta and Asthimajjagata vata (disorders of musculoskeletal origin). Objectives: By considering AVNF as Vatarakta, Asthimajjagata vata has attempted in the present study to evaluate the efficiency of Ayurvedic formulation in the conservative management of AVNF. Method-A case of AVN with bilateral femoral head presented with complaints of pain in the bilateral hip region with difficulty in routine work, i.e. walking, sitting, squatting, along with a change in gait. Initially, the patient was treated with Manjishtadi Kshara Basti, followed by Manjishtadi Ksheera Basti and Anuvasana Basti with Panchatiktaka gritha as per Karma Basti schedule (modified), followed by Shaman Aushadhi. Result-Patient was observed for symptomatic improvement based on a questionnaire over graded signs & symptoms, also observed for clinical examination before & after treatment, and the therapy provided marked relief from pain, tenderness, stiffness and improvement in the gait & hip joint movements. Conclusion: The study has shown that conservative management of AVNF can be managed effectively through Ayurvedic principles and improve quality of life.

Dynamic Oligopolistic Competition with Uncertainty and Supply Disruption Effects

We consider a finite-horizon discrete-time dynamic model of oligopolistic competition, with uncertain supply. The firms (retailers) make their decisions on quantities (sales) and orders of goods from a nonstrategic manufacturer taking into account uncertainty in demand parameters and available supply capacity. The retailers need to satisfy the joint available supply capacity constraint. The model is described as a game played over an event tree with given transition probabilities. We find a normalized equilibrium for the game with coupling constraints. The two-step procedure to find this equilibrium is described. We provide the necessary conditions of the equilibrium and examine different scenarios of uncertainties in the model by numerical simulations.

Multi-objective optimization and long-term performance evaluation of a hybrid solar-hydrogen energy system with retired electric vehicle batteries for off-grid power and heat supply

This paper presents a novel off-grid hybrid renewable energy system integrated with hydrogen production and retired electric vehicle (EV) batteries for combined power and heat supply to a small rural community. The system consists of photovoltaic (PV) panels, evacuated tube solar collectors, a proton exchange membrane fuel cell (PEMFC), an alkaline electrolyzer, compressed hydrogen storage tanks, and reused lithium-ion batteries from EVs. A new battery model is developed in the Transient System Simulation Program (TRNSYS) to capture the capacity degradation of retired batteries. A two-stage energy management strategy is proposed to regulate power flow and maximize solar energy utilization. The system is optimized for minimum power supply disruption, hot water supply disruption, energy waste, and annualized costs over a 20-year lifetime using a multi-objective NSGA-II algorithm coupling MATLAB and TRNSYS. Optimization results reveal tradeoffs between the competing objectives. Dynamic simulations show the water tank temperature fluctuates between 20 and 100 °C with mean values dropping slightly in later years due to battery degradation. Energy waste from components rises in later years for the same reason. The replacement interval for a retired EV battery module is around 2.5 years. The integrated system proves feasible for off-grid combined power and heat supply using solar energy and retired EV batteries as storage, though battery degradation impacts long-term performance.

Unraveling the Role of Endothelial Dysfunction in Osteonecrosis of the Femoral Head: A Pathway to New Therapies.

Osteonecrosis of the femoral head (ONFH) is a disabling disease characterized by the disruption of the blood supply to the femoral head, leading to the apoptosis and necrosis of bone cells and subsequent joint collapse. Total hip arthroplasty is not optimal since most patients are young. Multiple risk factors contribute to osteonecrosis, including glucocorticoid (GC) usage, excessive alcohol intake, hypercholesterolemia, and smoking. Continuous stimulation by many variables causes a chronic inflammatory milieu, with clinical repercussions including endothelial dysfunction, leading to thrombosis, coagulopathy, and poor angiogenesis. Immune cells are the primary regulators of inflammation. Innate and adaptive immune cells interact with endothelial cells to hinder the regeneration and repair of bone lesions. An in-depth examination of the pathological drivers of ONFH reveals that endothelial dysfunction may be a major cause of osteonecrosis. Understanding the involvement of endothelial dysfunction in the chronic inflammation of osteonecrosis could aid in the development of possible therapies. This review summarizes the role of endothelial cells in osteonecrosis and further explains the pathophysiological mechanism of endothelial dysfunction in this disease from the perspective of inflammation to provide new ideas for the treatment of osteonecrosis.

Economic Policy of Renewable Energy Adoption, Economic Policy of Digital Technology, Human Resource Management, Business Decision

Energy fluctuations and global economic directly hit Indian Subcontinent (Geopolitically, it generally includes the countries of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka) economy and social welfare, which are the net importer of energy sources. This study investigates the relationship between strategic petroleum reserve and welfare losses for Indian Subcontinent. The breakdown of crude oil energy supply has a significant impact on energy security & welfare losses. Oil supply security was quantified in terms of the Indian Subcontinent's oil vulnerability index (which accounts for 84 percent of global oil imports), and welfare losses based on oil supply disruption were calculated. Afghanistan is the most susceptible country in the Indian Subcontinent in terms of energy reserves, as per the composite index results, whereas India is the lowest vulnerable. Empirical findings pointed to a 30% deficit of oil supply as the cause of the most volatile pattern of oil pricing, which exacerbates the estimated welfare loss by a 40% drop in GDP, which is around $700 in the Indian Subcontinent & $9000 in the top oil-consuming countries. According to this analysis, the Indian Subcontinent should keep at least a hundred days' worth of strategic oil resources to avert social and economic losses due to oil price fluctuations.

Diplomatic activities of M.M. Litvinov in the USA during the Great Patriotic War (1941–1943)

The Great Patriotic War is one of the highlights in the history of Soviet-American cooperation. The USSR and the United States managed to overcome the inertia of mutual mistrust that persisted throughout most of the interwarperiod, taking together the lead in the fight against the Axis powers. However, rapprochement between the two future superpowers was neither plain nor swift; rather was it constantly hampered by mutual suspicion, aggravated by differences in their political cultures. Under these conditions, the fate of their alliance depended on the willingness of the ‘Big Three’ leaders to respect each other’s interest and concerns, as well as on the personal initiative and determination of individual politicians and diplomats. In this regard, the figure of M.M. Litvinov, appointed ambassador of the USSR to the United States at the most alarming and dangerous moment of the Great Patriotic War, deserves particular attention. Having played a major role in the Soviet-American cooperation in 1941–1943, M.M. Litvinov has been then forgotten for many years in both Soviet and Russian historiography. On the basis of new archive materials, the authors reexamine the activities of M.M. Litvinov as an ambassador to the United States and the specifics of his relationship with J.V. Stalin and V.M. Molotov during the period under review. The first section covers the initial steps of M.M. Litvinov in his new position. Special attention is paid to his efforts aimed at clarifying the Soviet position on the most sensitive issues of bilateral relations and establishing contacts with various groups of the American political, economic and intellectual elites. The second section analyzes M.M. Litvinov’s activities in the context of increasing contradictions between the Allies with regard to the opening of the second front and disruption of supplies under lend-lease. The authors show that M.M. Litvinov used all the diplomatic tools available to defend the interests of the USSR, instantly reacting to any changes in the moods of the U.S. military and political establishment and immediately reporting them to Moscow. In this context, the authors question the widespread claims in historiography about the ambassador’s excessive independence and willfulness. On the contrary, M.M. Litvinov can be said to have consistently adhered to the official foreign policy line of the Soviet leadership in both his speeches and practical steps. This indicates the need for further study of the M.M. Litvinov’s figure in order to avoid oversimplified, cliched assessments of this personality.

Enhancing Supply Chain Resilience in Coal Mining: A Review of Managing Disruptions

Objective – Coal mining operations encounter substantial risks and uncertainties that originate from a wide array of sources, encompassing but not limited to natural calamities, supplier disruptions, market volatilities, regulatory modifications, and geopolitical instability. This study aims to conduct a comprehensive literature review on supply chain resilience in the coal mining industry and pinpoint potential avenues for further investigation. Methodology – A systematic literature review (SLR) was utilized to examine a total of 115 studies in the field of management and the coal mining supply chain. The studies were published from 2010 to 2023. The vulnerabilities and resilience strategies within the coal mining supply chain are the focal points of our research. We have integrated viewpoints from the domains of management and the coal mining supply chain to support our analysis. Findings – Challenges such as resource distribution, government policies, and maintenance are prevalent, pointing to the need for strategies that enhance performance through dynamic optimization and incentivizing integration. Practitioners must identify vulnerabilities in the coal mining supply chain to proactively anticipate and effectively manage potential disruptions, thus bolstering operational resilience. Novelty –This study fills the gap in extant literature by investigating the sequential application of supply chain resilience in the context of coal mining operations using the integrative view of supply chain nodes.

Optimal resilience strategy for manufacturers to deal with supply disruptions: Investment in supply stability versus dual sourcing

Enhancing supply chain resilience is fundamental to the stable development of manufacturing enterprises. By comparing three resilience strategies (investment in fixed supplier for stable supply, dual sourcing by adding backup suppliers, and hybrid strategy), we investigate their effects on improving supply chain resilience under supply disruption and selecting resilience strategies for manufacturing enterprises in a complex supply chain environment. We then propose a corresponding management approach for manufacturers. This study reveals the following: (1) Compared with the non-resilience strategy, the investment strategy for supply stability and hybrid strategy may adversely impact the manufacturer’s profits while concurrently enhancing expected sales when the manufacturer’s investment cost is high, whereas the dual sourcing strategy is an effective strategy to increase the manufacturer’s expected profit. (2) Compared with investment and dual sourcing strategies, the hybrid strategy has a lower wholesale price but not always a lower sale price. (3) Manufacturers who prefer supply stability always adopt a hybrid strategy to ensure maximum expected sales volume; manufacturers who prefer profit adopt a hybrid strategy only when the investment cost is within a certain range; otherwise, they adopt a dual sourcing strategy to obtain higher profits. (4) Under an asymmetric sourcing strategy, when suppliers’ costs of production differ significantly, manufacturers adopting dual sourcing and hybrid strategies do not always increase sales, and adopting an investment strategy for supply stability is a more sales-resilient strategy. (5) The results of manufacturer resilience strategy selection under a multi-product supply chain are similar to those for a single product.

Research on the efficiency optimization of food reserve under the complementary reserve mode of government and enterprise in China

Food reserve is the cornerstone of national strategic security. China strives to build a complementary reserve system between government and enterprises, and how to improve the efficiency of food reserves is a matter of great concern to the government and society. Based on the analysis of the connotation of food reserve efficiency, this paper constructs the revenue function and the cost function of food reserve in an emergency and uses the cost–benefit method to explore the best ratio of government reserve, corporate social responsibility reserve, and commercial inventory when maximizing the efficiency of food reserve. This ratio is closely related to the total food reserve, the scale of supply interruption, the reserve cost of food stored by enterprises, and the government’s subsidy cost for the social responsibility reserve. The unit subsidy cost of government to social responsibility reserve is inversely proportional to the proportion of corporate social responsibility reserve to corporate reserve. Doing a good job in the social responsibility management of food enterprises is an effective way to improve the efficiency of food reserves. To expand the scale of social responsibility reserves and realize “storing food in enterprises,” the subsidies given by the government for corporate social responsibility reserves should not be too high. Taking food social responsibility reserve as an important part of corporate social responsibility, it’s the key to promoting enterprises to actively undertake food social responsibility reserves. The conclusion of this paper provides a theoretical basis and decision-making reference for how to improve the efficiency of food reserves.

Is interest rate hiking a recipe for missing several goals of monetary policy—beating inflation, preserving financial stability, and keeping up output growth?

After the corona crisis, and even more so when the war in Ukraine struck, the price levels of all goods in the US and Europe rose surprisingly quickly and persistently. The FED began in March 2022 and the ECB in July 2022 with historically unique interest rate increases to combat the wage-price spiral that had not yet begun. In this article we show that energy, commodities and food were the main drivers of inflation. For this reason, central banks' goal of weakening demand for labor through historically large interest rate hikes seems unwise. We argue that the current measures cannot achieve all of their objectives: slowing inflation, stabilizing financial markets and sustaining growth. If interest rates remain high, but external forces emerge with a lasting effect and keep inflation rates high, especially in smaller emerging countries, it will be difficult to counteract this on a country or regional basis through high interest rate policy and national control of the price- and wage-Phillips curve. Significant negative side effects of interest rate hikes increase the risk of not making the necessary investments and, in particular, weaken the bargaining power of particularly vulnerable employment groups. Other tools are needed to curb inflation and keep it under control, for example more investment in sectors with supply disruptions and a massive expansion of investment in renewable energy.

Fatty Acids Play a Critical Role in Mitochondrial Oxidative Phosphorylation in Effector T Cells in Graft-versus-Host Disease.

Although the role of aerobic glycolysis in activated T cells has been well characterized, whether and how fatty acids (FAs) contribute to donor T cell function in allogeneic hematopoietic stem cell transplantation is unclear. Using xenogeneic graft-versus-host disease (GVHD) models, this study demonstrated that exogenous FAs serve as a crucial source of mitochondrial respiration in donor T cells in humans. By comparing human T cells isolated from wild-type NOD/Shi-scid-IL2rγnull (NOG) mice with those from MHC class I/II-deficient NOG mice, we found that donor T cells increased extracellular FA uptake, the extent of which correlates with their proliferation, and continued to increase FA uptake during effector differentiation. Gene expression analysis showed the upregulation of a wide range of lipid metabolism-related genes, including lipid hydrolysis, mitochondrial FA transport, and FA oxidation. Extracellular flux analysis demonstrated that mitochondrial FA transport was required to fully achieve the mitochondrial maximal respiration rate and spare respiratory capacity, whereas the substantial disruption of glucose supply by either glucose deprivation or mitochondrial pyruvate transport blockade did not impair oxidative phosphorylation. Taken together, FA-driven mitochondrial respiration is a hallmark that differentiates TCR-dependent T cell activation from TCR-independent immune response after hematopoietic stem cell transplant.

FGR-associated placental insufficiency and capillary angiogenesis involves disruptions in human placental miRNAs and mRNAs

Fetal growth restriction (FGR) is one of the most common pregnancy complications culminating in adverse fetal outcome, including preterm birth, neonatal mortality and stillbirth. Compromised placental development and function, especially disruption in angiogenesis and inadequate nutrient supply are contributing factors. Fetal sex also influences placental function. Knowledge of gene expression changes and epigenetic factors contributing to placental dysfunction in FGR pregnancies will help identify biomarkers and help target interventions. This study tested the hypothesis that FGR pregnancies are associated with disruptions in miRNA - an epigenetic factor and mRNAs involving key mediators of angiogenesis and microvessel development. Changes in expression of key genes/proteins involved in placental dysfunction by RT-PCR and immunohistochemistry and miRNA changes by RNA sequencing were undertaken with term placenta from 12 control and 20 FGR pregnancies. Findings showed changes in expression of genes involved in steroidogenesis, steroid action, IGF family members, inflammatory cytokines and angiogenic factors in FGR pregnancies. In addition, upregulation of MIR451A and downregulation of MIR543 in placentas from FGR group with female newborns and upregulation of MIR520G in placentas from FGR group with male newborns were also noted. MIR451A and MIR543 have been implicated in angiogenesis. Consistent with gene changes, CD34, the microvessel angiogenesis marker, also showed reduced staining only in female FGR group. These findings provide evidence that epigentically regulated gene expression changes in angiogenesis and capillary development influence placental impairment in FGR pregnancies. Our preliminary observations also support for these changes to be driven in a sex-specific manner.

WATER MANGEMENT IN SOCIAL HOUSING, STRETEGIES FOR SUSTAINABLE USE

Water is considered as a finite resource, in this context, studies suggest that by 2050, one in four people in the world will be affected by problems related to water service. In Ecuador, there is an alarming problem concerning the lack of awareness in the efficient use of water, since the daily consumption of liters per capita is 237 liters, which doubles the consumption recommended by the World Health Organization (WHO) and 40% higher than the regional average. The Sustainable Development Goals 6 and 11 aim to achieve universal and equitable access to water, sanitation and hygiene services by 2030. This research aims to propose sustainable strategies to optimize the use of water in single-family homes of social interest based on the results of the Ciudad Victoria, Loja-Ecuador housing complex. It was developed in four phases: climate data collection, satisfaction and demand surveys, housing characterization, data tabulation to propose strategies validated in water demand scenarios using CYPECAD MEP software. Data are obtained on the consumption of water used for household chores and 310-liter sanitary appliances, exceeding the 100-liter recommendation stated by the WHO. In this study, the data was alarming as households experience water supply interruptions throughout the year, and they lack reserve systems. Implemented strategies enabled a reduction in water consumption of between 30% and 50% per household.

Situation-Aware Load Restoration Considering Uncertainty and Correlation

In order to minimize power supply interruption to customers, power system restoration needs to be performed rapidly after a blackout. With the integration of intermittent renewable energy and flexible loads, power system load patterns are becoming more uncertain. The goal of this paper is to tackle the challenging task of developing a secure yet speedy load restoration planning strategy considering load uncertainty. The key is to leverage the real-time measurements of the restored load blocks to refine the statistical knowledge about the unrestored load blocks derived from historical data, such that the load restoration plans can be less conservative without harming security. Specifically, as the restoration process rolls forward and more loads are restored, we use a Kalman filter to update the probability distribution of the unrestored loads using the newly available measurements from the restored loads. With the updated distribution, a rolling-horizon load restoration problem for load-pickup decision making is formulated with given specified confidence levels under frequency, voltage, and power flow constraints. The effectiveness of the proposed method is evaluated through case studies on the IEEE 39-bus test system and the NPCC 140-bus system. Results demonstrate that the proposed method can restore loads more quickly and securely than conventional methods under load uncertainty.

Review: Rhenium and its smelting and recycling technologies

Rhenium is utilized as an additive to improve the high-temperature strength and stability of materials, such as nickel-based superalloys, which are employed in jet engine turbine blades, alloys for ultrahigh-temperature thermocouples, and platinum catalysts, which are used in oil refining. Currently, around 80% of rhenium demand is for superalloy production, and this demand has been increasing with the increase in demand for aircrafts. The abundance of rhenium in the earth's crust is only 1 ppb (10−9), which is less than those of platinum and gold. Owing to the rare and unevenly distributed nature of rhenium, there is the risk of supply disruption and rapid increases in its price. In this article, the recent situation of rhenium and its compounds are reviewed, especially with respect to their demand, distribution characteristics, smelting, and recycling. Some of the technologies recently developed for smelting and recycling rhenium are also introduced.

Photosynthesis of rice leaves with a parallel venation is highly tolerant to vein severing.

Vein severing in plants caused by leaf damage is common in fields where crops are cultivated. It is hypothesized that leaves with complex reticulate venation can withstand hydraulic disturbances caused by vein severing, thereby preserving leaf carbon assimilation. However, limited research focuses on vein damage of leaves with parallel venation. We studied how vein-severing affected the photosynthetic traits of rice (Oryza sativa) leaves in seconds, minutes and days, under varying water-demand conditions and differing extents of water supply disruption. Rice leaves completely lost their photosynthetic capacity within 2.5 minutes after excision. Severing the midrib resulted in reduced light-saturated photosynthetic rate (A), stomatal conductance (gsw ) and transpiration rate (E) by 2.6, 6.8 and 5.9%, respectively, already after thirty minutes. We further investigated the photosynthetic trait responses to various extents of leaf width severing, while keeping the midrib functional. Surprisingly, A, gsw and E in the downstream area of the severed leaves largely remained stable, showing minimal variation across different leaf width severing ratios. These traits declined only slightly even under increased ambient light intensity and leaf-to-air vapor pressure deficit. This sustained photosynthesis post-severing is attributed to the efficient lateral water transport. Long-term leaf damage slightly but not significantly, impacted the downstream photosynthetic traits within five days post-severing. However, a more pronounced reduction in gas exchange during leaf senescence was observed nine days after severing. These findings suggested that rice leaves can tolerate hydraulic disturbances from vein severing and maintain functionality under various conditions, which is crucial for crop yield stability. However, long-term consequences require further investigation.

Design of resilient and viable sourcing strategies in intertwined circular supply networks

This study examines the effects of intertwining and circularity on the design of resilient and viable sourcing and recovery strategies in supply chains. We first construct a case study where the supply chains of three industries (i.e., automotive, healthcare, and electronics) frame an intertwined supply network (ISN). Through a discrete-event simulation model developed in anyLogistix, we examine the impact of disruptions in supply and demand on the performance of individual supply chains and the ISN as a whole. We test the performance of several sourcing strategies and their combinations. A special focus is directed toward shared reverse flows. The results show that disruption impact and recovery processes in the Circular ISN do not always follow conventional patterns known from the resilience of individual supply chains due to intertwining and circularity effects. We offer some managerial recommendations for the design of resilient sourcing strategies in the ISN context that are triangulated around collaborative sourcing practices, coordinated production planning, shared reverse flows, and visibility in inventory management.

Triggering triboelectric nanogenerator antibacterial Activities: Effect of charge polarity and host material correlation

Triboelectric nanogenerators (TENGs) offer promising motion-driven energy harvesting for human–machine interactions, particularly in wearable healthcare and biomedical devices. However, direct skin contact demands addressing aggressive bacterial growth risks. The “triangle” interaction between bacteria, electrical stimulation, and host materials has been investigated comprehensively in the present study to facilitate appropriate self-antibacterial designs for TENGs. In so doing, it was revealed that the growth of negatively charged bacterial models (Escherichia coli and Staphylococcus aureus) was inhibited by induced positively charged substrates (Al or graphene oxide (GO)), regardless of the host material's composition due to the direct electrostatic interactions. Electron capture from the bacterial respiratory chain by the substrates leads to the interruption of the bacterial energy supply. In response to negative charges, however, an appreciable host-dependent antibacterial behaviour was observed, with Al showing a negligible bactericidal effect, while GO exhibited robust antibacterial properties. This effect was assigned to reactive oxygen species (ROS) generation, triggered by shuttling the negative charges to the oxygen functional groups in GO, suppressing bacterial growth efficaciously. The observed correlation between the electrostatic charge polarity and the material composition of the substrates (hosting the bacteria) highlights the superiority of ROS induction in the antibacterial properties of TENG. These findings pave the way for developing innovative approaches to control bacterial growth effectively and enhance the applicability of TENGs as advanced wearable devices with inherent antibacterial capabilities.

Evaluation of Biomass Energy Policy Implementation in Indonesia to National Defense Support

Biomass energy is recognized as having strategic potential in overcoming energy security challenges and its participation to reduce the impact of environmental problems. The research-purpose is to evaluate how implementing a biomass energy policy can support national defense and sustainability. Through the framework of the literature, this study describes the concept of biomass energy and examines its relation to national defense. Energy policy analysis and reversed with energy security in Indonesia are also obtained from the reflection of the literature. The results show that biomass energy can strengthen the security of a country's energy supply by diversifying energy sources and reducing dependence on imported fossil fuels. This will support the operational defense system in dealing with fluctuations in energy prices and supplies. The implementation of biomass energy also has the potential to increase national energy independence, reduce the risk of energy supply disruptions, and strengthen national resilience. Utilization of biomass energy also contributes to improving climate change and negative environmental impacts. With the right technology, reductions in greenhouse gas emissions can be achieved, supporting environmental sustainability goals and securing the future of national defense

Identifying the Role of Knowledge-Intensive Business Services in the Korean Economy as a Sustainable Innovation Tool Using Input–Output Analysis

This study aimed to determine the role of KIBSs as a tool for sustainable innovation in a country’s economic system. Specifically, the degree and role of their impact on the Korean economy were analyzed and compared for the entire KIBS sector, T-KIBSs (a new technology-based professional service), P-KIBSs (a traditional professional service), and every subsector. For this purpose, the demand inducement model, supply inducement model, and interlinkage effects method were applied using the 2019 input–output table published in 2022. The analysis showed that the indirect production inducement effect of the entire KIBS industry on other industries was KRW 0.800, the indirect added value inducement effect was KRW 0.330, and the supply disruption effect was KRW 1.144. For T-KIBS, the indirect production inducement effect was KRW 0.687, the indirect added value inducement effect was KRW 0.272, and the supply disruption effect was KRW 0.730. For P-KIBSs, the indirect production inducement effect was KRW 1.472, the indirect added value inducement effect was KRW 0.646, and the supply disruption effect was KRW 2.657. Finally, regarding the economic ripple effect of the KIBS subsector, legal and management support services and advertisements corresponding to P-KIBSs showed higher figures than the T-KIBS subsectors in all sectors, including production inducement, the added value inducement effect, and the supply disruption effect. These results revealed that in the South Korean economic system, KIBSs contribute to production and value addition across all industrial sectors. It is apparent that the absence of supply significantly disrupts other industries. Furthermore, production inducement effects are evenly distributed among all the KIBS subsectors in the secondary and tertiary sectors, while the value-added effects have a greater impact on the tertiary sector. In terms of the supply shortage effects, the secondary sector experiences a more significant impact. This underscores the crucial role of KIBSs in sustaining and enhancing overall economic activity in South Korea.
