Secondary data has been used as source of information that obtained by the publication of financial reports that submitted by the Indonesia Stock Exchange (IDX). This study implemented the purposive sampling strategy to select 180 manufacturing companies which have been registered on the Indonesia Stock Exchange between 2018 and 2$020 as research samples. Normality test, heteroscedastic test, autocorrelation test, multicollinearity test, coefficient determination test, linear regression analysis and t-test, those are analysis methods used in this research. The t-test revealed that the characteristics of the commissioners has impact to the company’s dividend policy. While gender representative on the board of commissioners has negatively impacts on dividend policy, number of commissioners and free cash flow both positively affect the dividend policy. The policy relates to dividend distribution did not influence the proportion of independent commissioners, firm size or profitability. However, dividend policy has greatly affected by free cash flow. The research outcomes showed that the proportion of independent commissioners in a company usually lower than the total of commissioners owned by the company. Those Companies tends to allocate retained earnings to develop more profitable projects to get maximum profits. Companies that generate large inflows of free cash are more likely to make large dividend payments to reduce waste on unprofitable projects.

Published: May 2023

Security method of data transmission process has been growing rapidly with the science of cryptography. Cryptography can provide security services that includes security aspects like confidentiality, data integrity, authentication and non-repudiation. Modern cryptography uses a key that must be kept secret to overcome the problem of cryptographic security. Problem in the use of the same key by two entities that communicate with each other in exchanging messages is a way to distribute the key. This problem can be overcome by using public-key cryptography, which allows users to communicate securely without a shared secret key. Digital signature is the application of public-key cryptography. When accessing important digital documents, it is necessary to verify the signature given. Implementation of digital signature always requires a hash function. Hash function used in this research namely SHA-256, SHA-384 and Tiger. Federal Information Processing Standards (FIPS) set the cryptographic standard for digital signatures is the Digital Signature Standard (DSS). Algorithms included in the DSS are the Digital Standard Algorithm (DSA), Ron Rives, Adi Shamir, and Leonard Adleman (RSA) and Elliptic Curve Digital Signature Algorithm (ECDSA). So it is necessary to test the best digital signature implementation strategy that can be used by optimizing the performance of the hash function. Performance testing of the three algorithms is done by making an application using a computer programming language C++. Implementation program using C++ class library for cryptographic scheme that is Crypto++ Library 5.6.0. Class libraries used in the classes functions for digital signatures. On the application of digital signatures generated, conducted tests is done by combining each hash function algorithm with each of the DSS in order to compare their performance in terms of time and memory usage. Against the test results are then analyzed using statistical tests. The result shows that pair of Tiger hash function and DSA algorithm is the best combination.

This research aims to provide several ways that can be done by the Indonesian government on how to use the development of information technology that is now available and especially in the Republic of Indonesia. The data presented in this research journal can be used as a reference as a way to eradicate corruption, and can help the government in eradicating the disease that has undermined the Indonesian State, namely corruption or fraud. Corruption is one of the causes for the inadequate use of state revenues, which can be in the form of taxes, PNBP, customs etc. So that indirectly it can affect the development process in Indonesia, where the source of funds for the construction of public facilities, health and education comes from Indonesia's state revenue. This study uses an approach based on quantitative analysis methods with survey results based on data on the daily life of Indonesians in various circles of society carried out by various survey bodies or institutions in various countries that remain focused on the use of technology in Indonesia so that contrasting ideas can arise. which can shed some light on those who care about this country to fight for their rights which are taken away by the corruptors and other rats of the country. The use of technology can not only be used to prevent acts of corruption but can also be done in eradicating it, this is possible because the development of this information technology has reached a government system where everything someone does must have digital traces left such as corruption. This study uses a data presentation method with descriptions, charts and survey results.

The Concept of Justice in the Perspective of Greece Philosophy and its Relevance to the Development of Modern Political Law
Authors: Wahyudi Ade Arga , Marlian Arif Nasution  , Paisal Rahmat
Published: May 2023

The concept of justice will continue to develop in line with social developments. Justice in life is an important need for humans so that everyone can balance between demanding their rights and carrying out their obligations in an effort to achieve the truth. Thus, truth and duty must be harmonious and balanced in life. The development of legal thought has gone through a long journey from classical to modern times. The number of understandings that developed starting in the 20th century had an impact on increasingly rational legal learning. The law is just a collection of words when the law does not achieve justice. When the law does not recognize justice, then the law is meaningless. Legal formulation is the harmony between legal certainty and legal proportionality.

Published: May 2023

We present the first results study of the effects of the powerful gamma-ray burst GRB 221009A that occurred on 2022 October 9, and was serendipitously recorded by electron and proton detectors on board the four spacecraft of the NASA THEMIS mission. Long-duration gamma-ray bursts (GRBs) are powerful cosmic explosions, signaling the death of massive stars, and, among them, GRB 221009A is so far the brightest burst ever observed due to its enormous energy (E

γ iso ≈ 1055 erg) and proximity (the redshift is z ≈ 0.1505). The THEMIS mission launched in 2008 was designed to study the plasma processes in the Earth’s magnetosphere and the solar wind. The particle flux measurements from the two inner magnetosphere THEMIS probes, THA and THE, and two outer probes (renamed ARTEMIS after 2010), THB and THC, orbiting the Moon captured the dynamics of GRB 221009A with a high time resolution of 4 (up to 8) measurements per second. This allowed us to resolve the fine structure of the GRB and determine the temporal scales of the two main bursts’ spiky structure, complementing the results from gamma-ray space telescopes and detectors.
The Bobovica Village on The Visocica Mountain
Authors: Hadrovic Ahmet
Published: May 2023

The Bobovica village is located on the northern slopes of the Visocica mountain (Geographic coordinates: 43º38'27.83''N, 18º13'47.60''E, elevation: 1306). It belongs to the municipality of Trnovo, and it is 17.6 km away from Trnovo by air. The main resources of the village are its geographical position on the slopes of Visocica (on which there are extensive pastures), a lot of arable land, a wealth of sources of drinking water, the proximity of the Rakitnica river (whose power was traditionally used to operate water mills) and good traffic connections with other villages on the Bjelašnica plateau. The Bobovica village was burned down in the 1992-1995 war, with rarely preserved traditional structures. After the war, new houses were built, in new locations and next to the ruins of old houses. At the same time, the newly built buildings sometimes follow the patterns of traditional architecture, but, as a rule, they are made with a modern disposition, design and materialization. After the war, some facilities were built that did not exist before.
According to the theory of Architecturally Defined Space (ADS) developed by the Author in 1987, the village of Bobovica will be observed in this paper as a system through consideration of its four basic elements: Environment, Man, Boundaries and Perspectives. The simultaneous presentation of these elements will establish their mutual cause-and-effect relationship and will not leave out anything that is important for the formation of the image of this space.
Temporal trends in the accumulation of alien vascular plant species through intentional and unintentional introductions in Japan
Authors: Egawa Chika , Koyama Asuka
Published: May 2023

Clarifying the temporal trends of alien plant accumulation is increasingly important for informing global and national management efforts to decelerate biological invasions, following the adoption of Target 6 of the Kunming-Montreal Global Biodiversity Framework. However, such trends have not yet been analysed in many countries including Japan, which has the highest number of naturalised alien plant species among islands. To clarify the past and recent trends in the accumulation of alien plant species in Japan, we compiled a dataset of the year of first record for 1,463 alien vascular plant species deliberately and accidentally introduced and analysed the changes in the annual number of first records over time for each overall, intentional and unintentional introductions. We found that, overall, the annual number of first records of alien plant species in Japan began to increase in the late 1800s, and the increase continued until the late 1950s, with an estimated maximum of 15.7 new species per year. The increase then halted by 1960 and began a slow decline; the estimated average records per year between 1991 and 2000 dropped to 13.3 species. Since 1900, the annual number of first records associated with intentional introductions has more than doubled the number linked to unintentional introductions. Additionally, the proportion of invasive species brought through intentional introductions was larger than that brought through unintentional introductions. We highlight that while Japan experienced a rapid accumulation of alien plant species, including invasive species, by the 1950s, the rate of accumulation showed signs of saturation by 1960 and has since been slowly declining. Further deceleration and prevention of the introduction of invasive alien species, as targeted in the Kunming-Montreal Global Biodiversity Framework, may be achieved through increased investment in pathway management, especially management of intentional pathways.
Culture et civilisation comme réponse à la crise du sens du travail : de l’humanisme d’Adriano Olivetti à sa postérité
Authors: Meattini Serena
Published: May 2023

Cette contribution invite à considérer la culture et la civilisation comme réponse à la crise contemporaine du sens du travail, en attirant l’attention sur certaines expériences entrepreneuriales actuelles. À partir de l’analyse de l’humanisme d’Adriano Olivetti, en tant qu’exemple d’interaction profonde entre le travail, la culture et la civilisation, nous essayons d’y souligner l’anticipation de certaines questions importantes relatives au rapport entre éthique et entreprise aujourd’hui. Puis l’analyse se concentre sur la relation entre le monde de l’art et celui de l’entreprise, en particulier sur les interventions artistiques dans l’entreprise, afin de valoriser l’impact éthique possible, en avançant l’hypothèse d’une « possible postérité » de l’expérience entrepreneuriale mise en œuvre par Adriano Olivetti.

Loss aversion in sequential auctions
Authors: Rosato Antonio
Published: May 2023

I analyze sequential auctions with expectations‐based loss‐averse bidders who have independent private values and unit demand. Equilibrium bids are history dependent and subject to a “discouragement effect”: the higher is the winning bid in the current round, the less aggressive are the bids of the remaining bidders in the next round. Moreover, because they experience a loss in each round in which they fail to obtain an object, bidders are willing to pay a premium to win sooner rather than later. This desire to win earlier leads prices to decline in equilibrium. I also show how various disclosure policies regarding the outcome of earlier auctions affect equilibrium bids, and that sequential and simultaneous auctions are neither bidder‐payoff equivalent nor revenue equivalent.
Subjective information choice processes
Authors: Dillenberger David , Krishna R. Vijay , Sadowski Philipp
Published: May 2023

We propose a class of dynamic models that capture subjective (and, hence, unobservable) constraints on the amount of information a decision maker can acquire, pay attention to, or absorb via an information choice process (ICP). An ICP specifies the information that can be acquired about the payoff‐relevant state in the current period and how this choice affects what can be learned in the future. In spite of their generality, wherein ICPs can accommodate
any dependence of the information constraint on the history of information choices and state realizations, we show that the constraints imposed by them are identified up to a dynamic extension of Blackwell dominance. All the other parameters of the model are also uniquely identified.
Kaijō, Jakuchō, and Repurposing Wood for Sacred Images in Kamakura-Period Sculpture
Authors: Morse Samuel
Published: May 2023

Sculptors during the Kamakura period at times looked to unconventional sources for the material for their images and other projects. In 1183 Unkei used fragments of wood from the destroyed Great Buddha Hall at Tōdaiji for the rollers of two sets of the Lotus Sutra, and in 1206 an anonymous sculptor used a piece of charred wood, presumably from the same structure, for the right shoulder of the memorial portrait of Shunjōbō Chōgen, the monk who rebuilt the temple after it burned in 1180. Unkei’s father, Kōkei, employed wood from a sacred pillar beneath one of the halls at Ise Shrine for a now-lost image of Dainichi that was originally installed at Hosshōji in Kyoto in the late twelfth century. In 1256 the Nara sculptor Kaijō carved statues of Aizen Myōō and Jizō commissioned by the monk Jakuchō. The inscriptions indicate that they were fashioned from wood from the pillars of the Great Buddha Hall, most likely ones that remained after the conflagration. When preparing to carve the statues, Jakuchō and Kaijō consecrated the wood, and the sculptor and his two assistants maintained the Eight Pure Precepts while sculpting the image. Through the use of repurposed wood from structures with potent connections to Japan’s religious history, the installations of dedicatory objects, and their own personal devotions, Kaijō and other sculptors of the period embedded their works into multiple networks of meaning that reinforced the spiritual authority of their statues in ways that went far beyond their immediate visual impact.鎌倉時代の仏師たちは、彫像や他の作品に通常考慮外の木材使用に目を向けることがあった。1183年に運慶は、火災した東大寺大仏殿の焼け残りの木片を「法華経」二部の軸棒に使用した。また1206年には、無名の仏師が、おそらくこれも大仏殿の焼けた木片を俊乗房重源の遺像の右肩に使った。重源は、1180年に東大寺の焼尽後、再建のために奔走した僧だ。運慶の父の康慶は、今は存在しないのだが、12世紀後半に京都の法勝寺に安置されていた大日如来像に、伊勢神宮の正殿の床下の中央に立てられた心御柱を利用した。1256年には、奈良の仏師であった快成が、仏僧の寂澄からの依頼を受け、愛染明王坐像と地蔵菩薩像を制作している。銘文を読むと、これらの像が大仏殿の柱に使用されていた木材を転用されたということが分かる。おそらく、火災で焼け残ったものを利用したのだろう。彫像制作の過程においては、寂澄と快成は使用木材を清め、彫像を彫るあいだは、仏師及び二人の弟子共々、八斎戒を守り続けた。このようにして日本宗教史との強い繋がりのある建築物に使用されていた木材を転用し、納入品を入れ、個々の献身をすることにより、快成やこの時代の他の仏師たちは、視覚的迫力を超えた精神面での権威を強化し、その多面な意図を彫像に組み込んだのであった。

Authors: Zhao Liuyang , Sha Yezhou , Zhang Kaiwen , Yang Jiaxin
Published: May 2023

Blockchain and distributed ledger technologies have attracted massive attention from both legal communities and businesses. Asset securitization is the procedure in which an issuer designs a financial instrument that is marketable by combining or merging different financial assets into one group. However, most securitization occurs with loans and other assets that generate receivables, such as consumer or business debt of various types. This article discusses the possible benefits of blockchain during the securitization process using the deep learning-based adaptive online intelligent framework (DLAOIF). The benefits can be significant, from reduced costs, time, and fraud risks to increased safety, trust, and accuracy. Tracking financial assets on a blockchain can reduce dependence on credit rating organizations and allow investors to monitor asset performance and the associated risk more carefully. It should improve investor confidence and increase secondary market interest.

Authors: Li Guoliang , Wang Bing , You Maoyin
Published: May 2023

With the development of the internet, online education platforms have become the main means of acquiring knowledge for people. To improve the efficiency of user analysis, this paper proposes a framework for user sentiment recognition based on course review information of online education platforms. Firstly, according to the characteristics of the review data of online platforms, the authors use crawlers and open-source word separation tools to complete data collection and collation; secondly, the authors use TextCNN (text convolutional neural networks) and BILSTM (bi-long-short-term-memory) to combine to build a feature layer fusion text sentiment classification model. The results show that the average precision of the model built is 95.1% for the three sentiment classifications. Finally, a test of the reviews of new courses on online education platforms is conducted. The sentiment recognition rate of all three types of new courses exceeds 90%. Therefore, the proposed model provides new ideas for user analysis.
Numerical and Experimental Investigation of Axially Loaded Columns with Spiral Reinforcement
Authors: Krishan A.L. , Astafeva M.A. , Chernyshova Elvira P.
Published: May 2023

The study object is compressed reinforced concrete elements of different flexibility with indirect spiral reinforcement, and the study subject is their strength. A deformation method has been proposed to calculate the strength of these elements. The method is based on new dependencies for determining stresses and strains in a concrete core and spiral reinforcement at all loading levels. These dependencies have been obtained theoretically and reflect the main features of the force resistance of the elements. In the studied structures, the concrete core inside the spiral operates under volumetric compression. Moreover, as the axial shortening strain grows, not only axial compressive stresses increase gradually but also transverse stresses caused by the restraining impact of indirect reinforcement change constantly. This feature significantly complicates the deformation-strength calculation, which is based on the strain diagrams of materials. When calculating strength, flexibility is considered by increasing the initial eccentricity by the deflection value. When determining the deflection, the variable stiffness of the compressed bar along its length is considered. The comparison of the calculation and experimental results on the strength of compressed elements with indirect reinforcement indicates the reliability of the method proposed.
Compression Behavior of Pilar Octahedral Lattice Structures
Authors: Syrlybayev Daniyar , Perveen Asma , Talamona Didier
Published: May 2023

Lattice structures have a great potential in the fields like aerospace and biomedical, due to their outstanding properties like high strength, low mass, and good energy absorption capacity. With the development of the Additive Manufacturing technologies, there was an increasing attention towards these structures. The compressive behavior of the pilar octahedral lattice structure, which has the high strength to weight ratio was analyzed in this work. Lattice structures with three strut diameters of 1.5, 1.75, and 2 mm were built using Fused Filament Fabrication from Tough Polylactic Acid (PLA) plastic. Quasi-static compression tests were performed and two finite element models using beam elements with and without nodal beam diameter correction were proposed. It was found that as the diameter of the strut increases strength and elastic moduli are increased as well, while specific mechanical properties almost do not change. It was also confirmed from numerical and experimental results that lattice structure fails by forming a diagonal shear band. The relative error of the simulation without nodal correction in predicting the strength of the lattice with a 1.5 mm strut diameter was 1.58%. However, due to the inability of the beam element to model the behavior at the nodes properly its accuracy decreases for larger diameters. By modifying the model and using a nodal beam diameter correction, it has been possible to achieve a relative error of 0.58% and 12.15% for strut diameters of 1.75 and 2 mm respectively.
Application of a Nonlinear Deformation Model to the Analysis of Complete Moment-Curvature Diagrams of Reinforced Concrete Elements with Reinforcement A500
Authors: Dzyuba V.A. , Zhuravleva E.V. , Starkova A.S.
Published: May 2023

This article suggests a calculation procedure for the parameters of complete moment-curvature deformation diagrams with a down leg that can be used for the calculations of the multistorey monolithic building frameworks taking into account the specifics of reinforced concrete. To construct complete deformation diagrams for bending elements, a non-linear deformation model is used that is based on using the physical diagrams of the concrete and reinforcements to calculate the inner moments of cross-sections at all loading stages via balance and strain compatibility equations. Using this model, the authors researched complete moment-curvature deformation diagrams for the elements with different percentages of longitudinal tensile reinforcement that changes the bending properties of the structure. We used grade А500 steel as the reinforcement. The parameters of the tensile reinforcement diagram were determined in the tension testing of samples with constant deformation rates. The performed computer tests to calculate the moment-curvature diagram parameters for reinforced concrete beams reinforced with grade А500 efficiency rods and conventional grade A400 reinforcement rods with different longitudinal reinforcement congestion rates helped the authors assess the bending properties of the elements under conditions approaching their destruction and determine their efficient use in the calculations of building frameworks taking into account the redistribution of forces.

The fat body plays a central role in the regulation of the life cycle of insects and acts as the major site for detoxification, nutrient storage, energy metabolism, and innate immunity. However, the diversity of cell types in the fat body, as well as how these cell subsets respond to virus infection, remains largely unknown. We used single-nucleus RNA sequencing to identify 23 distinct clusters representing adipocyte, hemocyte, epithelial cell, muscle cell, and glial cell types in the fat body of silkworm larvae. Further, by analysis of viral transcriptomes in each cell subset, we reveal that all fat body cells could be infected by Bombyx mori nucleopolyhedrovirus (BmNPV) at 72 h postinfection, and that the majority of infected cells carried at least a medium viral load, whereas most cells infected by BmNPV at 24 h postinfection had only low levels of infection. Finally, we characterize the responses occurring in the fat body cell clusters on BmNPV infection, which, on one hand, mainly reduce their metabolic functions, involving energy, carbohydrates, lipids, and amino acids, but, on the other hand, initiate a strong antiviral response. Our single-nucleus RNA sequencing analysis reveals the diversity of insect fat body cells and provides a resource of gene expression profiles for a systems-level understanding of their response to virus infection.

In dairy cattle farming, heat stress largely impairs production, health, and animal welfare. The goal of this study is to develop a workflow and a numerical analysis procedure to provide a real-time 3D distribution of the THI in a generic cattle barn based on temperature and humidity monitored in sample points, besides characterizing the relationship between indoor THI and outside weather conditions. This research was carried out with reference to the study case of a cattle barn. A model has been developed to define the indoor three-dimensional spatial distribution of the Temperature-Humidity Index of a cattle barn, based on environmental measurements at different heights of the building. As a core of the model, the Discrete Sibson Interpolation method was used to render a point cloud that represents the THI values in the non-sampled areas. The area between 1-2 meters was emphasized as the region of greatest interest to quantify the heat waves perceived by dairy cows. The model represents an effective tool to distinguish different areas of the animal occupied zone characterized by different values of THI.

Background: Perioperative adverse cardiac events (PACE), a composite of myocardial infarction, coronary revascularization, congestive heart failure, arrhythmic attack, acute pulmonary embolism, cardiac arrest, and stroke during 30-day postoperative period, is associated with long-term mortality, but with limited clinical evidence. We compared long-term mortality with PACE using data from nationwide multicenter electronic health records.Methods: Data from 7 hospitals, converted to Observational Medical Outcomes Partnership Common Data Model, were used. We extracted records of 277,787 adult patients over 18 years old undergoing non-cardiac surgery for the first time at the hospital and had medical records for more than 180 days before surgery. We performed propensity score matching and then an aggregated meta‑analysis.Results: After 1:4 propensity score matching, 7,970 patients with PACE and 28,807 patients without PACE were matched. The meta‑analysis showed that PACE was associated with higher one-year mortality risk (hazard ratio [HR]: 1.33, 95% CI [1.10, 1.60], P = 0.005) and higher three-year mortality (HR: 1.18, 95% CI [1.01, 1.38], P = 0.038). In subgroup analysis, the risk of one-year mortality by PACE became greater with higher-risk surgical procedures (HR: 1.20, 95% CI [1.04, 1.39], P = 0.020 for low-risk surgery; HR: 1.69, 95% CI [1.45, 1.96], P < 0.001 for intermediate-risk; and HR: 2.38, 95% CI [1.47, 3.86], P = 0.034 for high-risk).Conclusions: A nationwide multicenter study showed that PACE was significantly associated with increased one-year mortality. This association was stronger in high-risk surgery, older, male, and chronic kidney disease subgroups. Further studies to improve mortality associated with PACE are needed.
Hormonal profile of survivors of breast cancer with fatigue: A pilot study
Authors: Gupta Shardool Vikram , Kaur Navneet , Madhu S.V.
Published: May 2023

Background & objectives:

One of the most common problems experienced by breast cancer survivors (BCSs) is fatigue. There has been little research about the status of hormones in breast cancer patients as an aetiology of cancer-related fatigue (CRF). Hence, a pilot study was conducted to assess the levels of hormones such as thyroid, cortisol, dehydroepiandrosterone sulphate (DHEAS), oestrogen and progesterone in BCSs with fatigue.

Methods:

BCSs with complaints of fatigue were assessed using the Brief Fatigue Inventory (BFI) tool and evaluation of the hormone profiles was done in moderate-to-severe fatigued survivors. Data collected were analyzed to look for any association between fatigue and altered hormonal levels.

Results:

In this study, 56 per cent (n=62) of survivors experienced moderate-to-severe fatigue out of 110 patients reporting fatigue. Thyroid functions were deranged in 22 patients (35.48%). The thyroid stimulating hormone (TSH) levels were found to have a significant negative association with the severity of fatigue, (P<0.05). Twelve patients (19.35%) had reduced DHEAS levels suggestive of impaired hormone synthesis in the adrenal gland. Twenty two postmenopausal survivors (35.48%) had raised oestradiol levels.

Interpretation & conclusions:

The findings of this study suggest that the hormonal milieu, especially thyroid hormone and DHEAS may have a role in CRF experienced by BCSs and needs further exploration.
The kinetics of isotonic and hypertonic resuscitation fluids is dependent on the sizes of the body fluid volumes
Authors: Hahn Robert G.
Published: May 2023

Background and Aims:

The extracellular and intracellular fluid volumes (ECV and ICV) vary not only with age, gender, and body weight but also with the habitual intake of water. The present study examines whether the baseline variations in the ECV and ICV change the distribution and elimination of subsequently given infusion fluids.

Material and Methods:

Twenty healthy male volunteers underwent 50 infusion experiments with crystalloid fluid for which the fluid volume kinetics was calculated based on frequent measurements of the hemodilution using mixed-effects modeling software. The results were compared with the ECV and ICV measured with multifrequency bioimpedance analysis before each infusion started. The fluids were given over 30 minutes and comprised 25 mL/kg Ringer’s acetate (N = 20), Ringer’s lactate, 5 mL/kg 7.5% saline, and 3 mL/kg 7.5% saline in 6% dextran 70 (these fluids, N = 10).

Results:

A large ICV was associated with a small extravascular accumulation of infused fluid, which increased the plasma volume expansion and the urinary excretion. With hypertonic fluid, a large ECV greatly accelerated urinary excretion. The body weight did not serve as a covariate in the kinetic models. Albumin was recruited to the plasma during infusion of both types of fluid. The hypertonic fluids served as diuretics. The infused excess sodium and osmolality were distributed over a 35% larger space than the sum of the ECV and ICV.

Conclusion:

A large ICV reduced the rate of distribution of Ringer’s solution, whereas a large ECV accelerated the excretion of hypertonic saline.
