Authors: Ismiyana Putri Dwi , Yudhi Putra Mardi
Published: July 2023

Perkembangan teknologi informasi dan keuangan telah mendorong penggunaan metode prediksi harga saham yang efektif. Dalam penelitian ini, dilakukan komparasi terhadap tiga algoritma populer, yaitu Regresi Linear (RL), Support Vector Machine (SVM), dan Neural Net (NN), untuk memprediksi perubahan harga saham GOTO dengan menggunakan aplikasi RapidMiner sebagai alat analisis yang kuat dalam mengimplementasikan dan membandingkan kinerja algoritma-algoritma tersebut. Untuk mengukur dan membandingkan kinerja ketiga model prediksi, peneliti menerapkan metode evaluasi 10 K-Fold Cross Validation dengan pembagian data 90:10. Analisis dilakukan berdasarkan hasil Root Mean Square Error (RMSE), yang merupakan indikator umum untuk mengukur sejauh mana perbedaan antara nilai prediksi dan nilai aktual dalam unit yang sama. Hasil analisa menunjukkan bahwa model Neural Net (NN) memberikan nilai RMSE terendah dengan angka sebesar 16.562. Ini menunjukkan bahwa model Neural Net memiliki tingkat akurasi yang lebih baik dalam memprediksi perubahan harga saham GOTO dibandingkan dengan model Regresi Linear (22.479) dan Support Vector Machine (31.326). Meskipun RL dan SVM juga memberikan prediksi yang cukup akurat, NN menonjol dengan performa terbaik. Penemuan ini menunjukkan bahwa algoritma Neural Net adalah pilihan yang lebih baik dalam memprediksi perubahan harga saham GOTO. Namun, penting untuk mencatat bahwa evaluasi dan pemilihan model harus selalu dipertimbangkan dalam konteks bisnis atau penelitian yang relevan.
Sino -Indian Political Relations: An Overview
Authors: Singh Ranjit , Singh Hakim
Published: July 2023

While discussing the political systems as well as the political leadership of both countries, an effort was made to understand the political and strategic relations between both neighbors e.g. India and China.  This paper examined the historical peaceful coexistence between the both, which has undergone a decline since the Chinese Communists won the Chinese Civil War and the annexation of Tibet. This has led to border disputes and economic nationalism. Both countries worked hard to re-establish their cultural, social, and economic ties, and eventually, China became India's most important trading partner. Currently, the two nations have established a strategic and collaborative alliance aimed at promoting peace and prosperity. This partnership is characterized by a significant level of involvement and enhanced comprehension in the areas of political, cultural, economic, and military cooperation. The foundation of their enhanced relationship is predicated upon a mutual comprehension of their respective concerns.
Computer use at work and carpal tunnel syndrome
Authors: Lisica Mandek Denis , Brborović Hana
Published: July 2023

There are many discussions regarding the impact of computer work, especially computer mouse use, in the development of carpal tunnel syndrome (CTS). The mechanism of such damage could be pressure or stretching of the median nerve in the carpal canal area. There is evidence that repetitive motion along with the use of force is a factor that contributes to the development of CTS, but computer work consists of mostly repetitive movements, without the use of force. Studies show that the prevalence of CTS in computer workers is similar to its prevalence in the general population. The general aim of this paper is to perform a literature search on the topic of whether there is a causal link between computer work and the development of CTS. The first specific goal is to try to quantitatively determine a relationship between exposure time and the development of symptoms, and the second specific goal is to try to set criteria, or guidelines, for the recognition of CTS as an occupational disease for those working on computers. A literature search on the databases ProQuest, PubMed, Google Scholar, and Cochrane Library. The key words used were: carpal tunnel syndrome AND computer work OR computer exposure OR keyboard use OR mouse use AND systematic review OR prospective cohort. The last search was performed on March 15, 2021. A total of 12 studies were included in this paper. The results were contradictory. Nine studies state that computer work does not pose an increased risk of CTS development. Two studies found that longer-term mouse use of more than 20 hours per week and keyboard use of more than 240,500,000 strokes per year may be associated with the development of CTS. One study showed people have a lower risk of developing CTSwhen working on a computer. We cannot determine with certainty the connection between computer work and the development of carpal tunnel syndrome. This calls into question the recognition of CTS as an occupational disease among those working on computers. Better planning and structured studies are needed to determine the intensity and duration of computer exposure and the level of damage to the median nerve, and then set criteria for the recognition of CTS as an occupational disease in these circumstances. Regardless of whether we recognize a particular disease as occupational, it is necessary to carry out preventive measures so that these health problems do not even occur, thereby keeping workers healthy and productive for as long as possible.

Bolesti uzrokovane čimbenicima okoliša obuhvaćaju poremećaje koji su uzrokovani različitim okolišnim čimbenicima te promjenama ponašanja stanovnika. Urbana područja diljem svijeta suočavaju se s velikim brojem čimbenika okoliša koji utječu na javno zdravlje, kao što su onečišćenje zraka, voda, buka, polutanti, gustoća prometa, prenapučenost u gradovima, smanjenje zelenih površina, itd. Pravovremeno otkrivanje i kvantifikacija rizičnih čimbenika okoliša, koji utječu na javno zdravlje, veoma je važna jer svaka intervencija na ovom području može smanjiti rizik od obolijevanja i poboljšati zdravlje stanovništva. Unutarstanične matriks metaloproteinaze (MMPs) lokalizirane su u različitim odjeljcima unutar stanice uključujući citosol, sarkomeru, mitohondrije i jezgru. Intracelularne MMPs pridonose patogenezi različitih bolesti. Cilj ovog preglednog rada je istražiti uloge matriks metaloproteinaza u razvoju bolesti respiracijskog sustava uzrokovanih čimbenicima okoliša te važnost njihovog određivanja kao potencijalnih pokazatelja ranih tkivnih oštećenja u ljudi. MMP su se dokazale, uz imunološki status, kao dobar biljeg za praćenje bolesti uzrokovanih čimbenicima okoliša. Osim u dijagnostici i monitoringu bolesti uzrokovanih čimbenicima okoliša, MMPs i njihovi tkivni inhibitori (TIMP, engl. tissue inhibitor of metalloproteinase) predstavljaju potencijalni cilj liječenja.

Published: July 2023

The use of an internet network in an organization cannot be divorced from the numerous types of challenges that occur inside it, particularly those connected to network service quality., In addition, the high demand for service users has become a severe issue where people believe that the network needs to be optimally utilized. This research examined the connection between ISP service quality and B2B customer loyalty to business Internet services. This work employs Structural Equation Modeling with Partial Least Square methodology for SEM data analysis (PLS-SEM). The research revealed a favourable and statistically significant correlation between BP trust and BP loyalty. Because BP believes in the quality and service of ISP providers, they are typically loyal to BP. In addition, NQ and SP have a sizeable direct association with client loyalty. Moreover, this research showed that QSTS had a good and substantial effect on BP's level of trust. Meanwhile, CSTS, NQ, and SP have a favourable and significant impact on BP value.

Published: July 2023

Underwater remotely operated vehicles (ROV) are important in marine industries to accomplish underwater exploration and surveying. The underwater environment makes it hard for ROV operators to control the manipulator while holding position simultaneously. This led to modelling and controller design for the vertical trajectory of ROV. In this paper, the System Identification (SI) modeling technique was used to model the vertical trajectory of the ROV. Then, the Proportional, Integral, and Derivative (PID) controller was implemented to control the trajectory. The SI modelling technique was used as it estimates the model based on the input and output relationship. MATLAB SI toolbox was used as the analytical software. Step and multiple step inputs were given to the system and the responses were recorded. The model with the best fit of 84.7% was selected and verified by comparing with actual output. The model response was then analyzed and the PID controller was implemented. The actual model had high percent overshoot (%OS) and steady state error (SSE). The PID implementation successfully reduced the %OS and eliminated the SSE.
ABSTRAK: Kenderaan bawah air kendalian jauh (ROV) adalah penting dalam industri marin bagi melaksanakan penerokaan dan pemerhatian bawah air. Persekitaran dalam air menyukarkan pengendali ROV bagi memanipulasi manipulator sambil memastikan kedudukan ROV secara serentak.

Published: July 2023

Three-dimensional printing has recently come into the spotlight due to its promising potential to create physically three-dimensional parts or structures through computer-aided design. While there are many options for 3D printing methods, photopolymerization 3D printing has garnered much attention because of its high resolution. However, the mechanical properties of photopolymerized 3D printed parts can vary widely depending on the manufacturing parameters and post-processing settings used. This research focuses on studying the effect of printing variables on the mechanical properties of samples printed using a Stereolithography machine (Formlabs, Form+3). Three variables are used: layer thickness (25 and 50 ?m), part orientation (X and Z directions), and post-curing. Also, eight groups of 3D-printed photopolymer specimens for twenty-four specimens are used for the tensile test results. The results showed the printing variables affected the mechanical properties of samples, which were proven by Young's modulus, ultimate stress, and ultimate strain.

Unmanned aerial vehicles UAVs have been developed and refined for decades. Using an integrated software system, autonomous unmanned aerial vehicles (UAVs) perform missions automatically and return to a pre-programmed point. Malaysia has a lot of unoccupied airspace, yet autonomous UAV applications and research are still rare. In critical conditions, autonomous UAVs must deal with a variety of environmental and flight issues. This project involves a decentralized 3D collision avoidance system for an autonomous UAV. Ultrasonic, infrared, and laser rangefinders were chosen for the 3D collision avoidance system. The UAV's obstacle recognition and collision avoidance performance are also tested in four experiments. In various flight conditions, the 3D collision avoidance system can identify several material types and opacities by integrating selected rangefinders. Finally, the 3D collision avoidance system quickly reacts to obstacles in the X, Y, and Z axes.

Beyond Erasmus. Communication of European Universities alliances on social media
Authors: García-Gordillo Mar , Ramos-Serrano Marina , Rivas-de-Roca Rubén
Published: July 2023

The European Union has suffered several problems in recent years, which triggers a proactive action by its institutions to generate a united citizenry and awareness of the importance of the EU. In the field of higher education, the European Strategy for Universities born in 2019 aims to strengthen and developed a common university system. The Erasmus program has traditionally been identified as the main driver of integration, but the emergence of European universities may mark a new phase in the shaping of the European Public Sphere (EPS). In this sense, social media are the key communication tool for higher education centers. The objective of this work is to examine the activity on social media of the 40 consortia of European Universities belonging to the first and second calls. First, the presence on the different social networks of these entities is analyzed to establish a map of the alliances, based on the number of social networks used, the volume of followers, the coordinating university and the year of the call. After identifying Twitter as the most used network, a content analysis is carried out on 12 variables of all the messages published by these consortia since their creation, with the aim of determining whether the content published on their Twitter accounts is professional in tone. The results reveal scant interactivity that does not take advantage of the potential of social networks. However, there is a certain influence of the national cultures in terms of use of digital platforms in the different countries that head each consortium, with Spain and France being rather remarkable in this aspect. Likewise, the advantage acquired by first-generation consortia boosts their greater impact. This leads to a reflection upon the true transnational dimension of the communication implemented by these universities.
Controllability and optimal speed-in-action of linear systems with boundary conditions
Authors: Aisagaliev S. , Korpebay G.T.
Published: July 2023

The paper proposes a method for solving the problem of optimal performance for linear systems of ordinary differential equations in the presence of phase and integral restrictions, when the initial and final states of the system are elements of given convex closed sets, taking into account the control value restriction. The presented work refers to the mathematical theory of optimal processes from L.S. Pontryagin and his students and the theory of controllability of dynamic systems from R.E. Kalman. We study the problem of optimal speed for linear systems with boundary conditions from given sets close to the presence of phase and integral constraints, as well as constraints on the control value. A theory of the boundary value problem has been created and a method for solving it based on the study of solvability and the construction of a general solution to the Fredholm integral equation of the first kind has been developed. The main results are the distribution of all controls’ sets, each subject of which transfers the trajectory of the system from any initial state to any final state; reducing the initial boundary point to a special initial optimal control problem; constructing a system of algorithms for the gamma-algorithm study on the derivation of problems and rational execution with restrictions on the solution of the optimal speed’ problem with restrictions.
On quasi-identities of finite modular lattices. II
Authors: Basheyeva A.O. , Lutsak S.M.
Published: July 2023

The existence of a finite identity basis for any finite lattice was established by R. McKenzie in 1970, but the analogous statement for quasi-identities is incorrect. So, there is a finite lattice that does not have a finite quasi-identity basis and, V.A. Gorbunov and D.M. Smirnov asked which finite lattices have finite quasiidentity bases. In 1984 V.I. Tumanov conjectured that a proper quasivariety generated by a finite modular lattice is not finitely based. He also found two conditions for quasivarieties which provide this conjecture. We construct a finite modular lattice that does not satisfy Tumanov’s conditions but quasivariety generated by this lattice is not finitely based.

In this paper, we consider a boundary control problem for a parabolic equation in a segment. In the part of the domain’s bound it is a given value of the solution and it is required to find controls to get the average value of the solution. The given control problem is reduced to a system of Volterra integral equations of the first kind. By the mathematical-physics methods it is proved that like this control functions exist over some domain, the necessary estimates were found and obtained.
Development of a Prediction Model for Acute Kidney Injury after Colistin Treatment for Multidrug-resistant Acinetobacter baumanii Ventilator-Associated Pneumonia: A Pilot Study
Authors: Seanglaw Dussadee , Morasert Thotsaporn
Published: July 2023

Objective: Multidrug-resistant Acinetobacter baumanii (MDR-AB) ventilator-associated pneumonia (VAP) is the major complication following hospital admission in Thailand, increasing morbidity and prolonging hospital stay duration. Treatment of MDR-AB VAP usually requires colistin which has highly nephrotoxic properties. Therefore, we aimed to develop a pilot prediction model for acute kidney injury (AKI) after colistin treatment.Material and Methods: We conducted a retrospective cohort study. All MDR-AB VAP patients who received colistin for at least 72 hours in Suratthani Hospital from January to July 2017 were eligible for inclusion. The primary outcome was the overall presence of AKI on days 3, 5 or 7 after colistin administration. Multivariable logistic regression analysis was used to develop the final prediction model.Results: Of 85 MDR-AB VAP patients, 51 (61%) developed AKI after colistin treatment. Nine factors, female, intensive care unit (ICU) admission, diabetes mellitus, systolic blood pressure (SBP), diastolic blood pressure (DBP), serum sodium, creatinine, blood urea nitrogen (BUN) and glomerular filtration rate were potential predictors of AKI. Multivariable logistic regression with backward stepwise selection revealed the best prediction model had four predictors: female, ICU admission, BUN, and DBP. The area under the receiver operating characteristic curve for the model in predicting AKI among MDR-AB VAP patients was 0.801 (95% confidence interval: 0.703, 0.898).Conclusion: The prediction model containing four predictors, female gender, ICU admission, BUN level, and DBP had fair to good performance in predicting AKI after colistin treatment among MDR-AB VAP patients.

Published: July 2023

Objective: To compare the postoperative analgesic effects of 0.2% ropivacaine with Dexmedetomidine (2 g/kg) and tramadol (2 mg/kg) among pediatric patients undergoing infra umbilical surgery.Material and Methods: This hospital based, randomized double blind interventional study included 60 pediatric patients, aged 1–7 years, having American Society of Anaesthesiology grade I and II, weighing 7-25 kg, and undergoing infraumbilical surgeries under general anesthesia. Subjects were randomly allocated into two groups to receive either: 2 mcg/ kg of Dexmedetomidine or 2 mg/kg of Tramadol, as adjuvant to 0.2% of Ropivacaine. Pain intensity was assessed using the pediatric observational Children’s Hospital of Eastern Ontario Pain Scale (CHEOPS) score. Rescue analgesia was given, when the CHEOPS score was ≥6. Duration of analgesia was defined as: the time period between administrations of block until rescue analgesia was given. Level of sedation was assessed by the Ramsay sedation score.Results: Kaplan Meier analysis showed that the median time to first rescue analgesia (duration of analgesia) was significantly (p-value<0.001) prolonged with Dexmedetomidine (780 minutes; 95% CI: 760.68–799.32 minutes) as compared to Tramadol (648 minutes; 95% CI: 635.92–660.38 minutes). Mean emergence time and duration of sedation were also significantly prolonged with Dexmedetomidine as compared to Tramadol.Conclusion: In pediatric patients undergoing infraumbilical surgeries, Dexmedetomidine as adjuvant to Ropivacaine provides an advantage of longer post-operative analgesia and lack of opioid related adverse events associated with Tramadol.

Published: July 2023

Objective: Diabetic foot ulcers (DFUs) are a diabetes mellitus (DM) complication with a high mortality rate. This research aimed to demonstrate a mortality prediction model in patients with DFUs.Material and Methods: This research conducted a case-control study based on secondary data from the medical records of DFU patients in Dr. Soetomo General Hospital, a tertiary referral hospital in Surabaya, Indonesia, between 2016-2018. The association between various risk factors and mortality was analyzed using bivariate and multivariate analyses to make a mortality prediction model.Results: 358 subjects (179 cases and 179 controls) were included in the final analysis. Septic shock was the major cause of DFU death. Both bivariate and multivariate analyses determined that 5 independent variables were associated with the mortality in DFU patients, namely albumin level (p-value<0.001 OR 16.52 CI 95% 3.42–79.86), sepsis (p-value<0.001 OR 23.47 CI 95% 5.80–26.85), renal function impairment (p-value<0.001 OR 3.41 CI 95% 1.87–6.21), cardiovascular complications (p-value<0.001 OR 2.93 CI 95% 1.64–5.25), and the severity level of the ulcers using Wagner’s classification (p-value<0.001 OR 6.80 CI 95% 3.77–12.27). The mortality prediction model showed a maximum score of 7, indicating a 98.4% mortality risk.Conclusion: Low albumin level, sepsis, renal function impairment, cardiovascular complications, and Wagner’s severity level IV–V of the DF ulcers were the predictors of mortality in DFUs.

Therefore, this study aims to find out what are the influences of gadgets on communication in the family using qualitative methods, namely by using interviews and observations. The results of this study show the influence of the use of gadgets in communication in the family is the deterioration of communication and relationships in the family, loss of empathy and concern for the outside environment and children feel foreign and parents lose their roles. The influence of the use of gadgets in family communication can occur due to excessive use of gadgets so that it can have a negative impact on parent-child communication in the family. The intensity of direct communication between parents and children becomes reduced because they are too engrossed in using gadgets, interaction and communication with the outside environment is also lacking which makes it difficult for children to empathize and care and parents who are addicted to gadgets will be more negligent with responsibilities at home so as to make children feel foreign because of lack of affection. From this study, it is hoped that future research can examine more deeply the influence of gadgets that can be caused by family communication and can make this research a reference in knowing what are the effects of gagdet on family communication. _____________________________________________________________ Salah satu pengaruh negatif meningkatnya pengguna gadget bagi umat manusia adalah pengaruh gadget terhadap pola komunikasi rumah tangga. Oleh karena itu penelitian ini bertujuan untuk mengetahui apa saja pengaruh yang ditimbulkan gadget terhadap komunikasi dalam keluarga dengan menggunakan metode kualititatif, yaitu dengan menggunakan wawancara dan observasi. Hasil penelitian ini menunjukan pengaruh dari penggunaan gadget dalam komunikasi dalam keluarga adalah memburuknya komunikasi dan hubungan dalam keluarga, hilangnya rasa empati dan kepedulian terhadap lingkungan luar dan anak merasa asing serta orang tua kehilangan perannya. Pengaruh penggunaan gadget dalam komunikasi keluarga dapat terjadi dikarenakan penggunaan gadget yang berlebihan sehingga dapat berdampak negatif pada komunikasi orangtua-anak dalam keluarga. Intensitas komunikasi langsung antara orang tua dan anak menjadi berkurang karena terlalu asyik menggunakan gadget, interaksi dan komunikasi dengan lingkungan luar juga kurang yang menimbulkan anak susah berempati dan peduli, orang tua yang kecanduan gadget akan semakin lalai dengan tanggung jawab dirumah sehingga membuat anak merasa asing karna kurang kasih sayang. Dari penelitian ini diharapkan untuk penelitian selanjutnya dapat mengkaji lebih dalam pengaruh gadget yang dapat ditimbulkan terhadap komunikasi keluarga dan bisa menjadikan penelitian ini sebagai acuan dalam mengetahui apa saja pengaruh gagdet terhadap komunikasi keluarga.

Day in day out of human life the use of metal is inevitable, metals are needed for different purposes such as  in construction of bridges houses, roads etc. but despite the availability of huge amount of metal, it does not meet the global demand thus this paper investigate the effect of reduction of power of heat loss on the cost of production of electric arc furnace. In order to achieve maximum precision during production, getting product at relatively reduced price has remained a major challenge to the scientists. The experiment was conducted at industrial scale whereby power of heat loss was varied from 7.707- 4.624 MW while energy consumption fell from 0.5463 to 0.5317 MW-Hour per ton and productivity q tremendously increased from 253.0 ton to 254.0 ton per hour . Data used were collected from active furnace in Zerepaves Metallurgical plant, Russia and further analyzed with software package for accuracy

This study focuses on developing a prototype for a seawater desalination system powered by solarpanel. The desalination process is heated by a solar collector and 150 WP solar panel. The primaryobjective is to design, develop, and evaluate the prototype's efficacy, affordability, and scalability.The efficiency was measured by the quantity of freshwater produced per unit of solar energy. Ofthe three distillation tests, it was determined that the addition of a heater enhanced theperformance of the system. However, the overall efficiency was limited due to the solar panel andcollector's low heat output. A positive correlation was observed between irradiance andtemperature, but incomplete evaporation indicated the need for additional research to optimizethe process. The system consisted of a solar collector, a heater, and a distillation apparatus. Threedistillation tests revealed that the addition of a heater improved the system's performance,resulting in a maximum achievable efficiency of 0.99% and the production of 16 ml of fresh water.This study demonstrates the potential for renewable energy sources to power seawaterdesalination and lays the groundwork for future sustainable desalination technologies despite itslimitations.

Relevance. It is known that antitoxic immunity saves from diphtheria, but does not prevent the carriage of Cd (tox+). Asymptomatic carriers of Cd (tox+) play a major role in maintaining the epidemiological process of diphtheria infection.

Aims. Characteristics of the population composition and specifics of the kinetic reactions of Cd (tox-) and Cd (tox+) simultaneously functioning among people.

Results. The functional features of the specific kinetic reactions of individual populations play an important role in the existence of microbial populations in human biotopes. The introduction of the corinephage tox+ gene into the symbiotic individual Cd (tox-) promoted the synthesis of the toxin and the adaptive stability of the Cd (tox-) population in the environment. Metabolites Cd (tox-) - autostabilizers of microbial growth form microecological symbiotic systems of human biotopes.

Conclusions. The use of the metabiotic drug Kodivac from symbiotic Cd (tox-) allows: to treat long-term carriers of Cd (tox+); reduce circulation of Cd (tox+) in the population; together with small doses of diphtheria toxoid to create protection against diphtheria; form symbiogenesis in human biotopes, suppressing dysbiotic inflammatory reactions.

In the study, the attention to the problems of formation and implementation of the state housing policy, in particular in the part of the development of the country's housing stock, is updated. The purpose of the study was to identify problematic aspects, as well as to substantiate effective mechanisms for regulating the development of the housing stock in Ukraine. The most problematic aspects of social housing construction in Ukraine are identified and the problems in this area, which have worsened in connection with full-scale military operations, are emphasized. Areas of improvement of the state policy of activation of social housing construction have been identified. Problematic aspects of state management of the development of the general housing stock of the state are pointed out. The most promising mechanisms that should be used to increase the efficiency of the state policy of increasing the volume of housing construction in Ukraine are identified, which in particular relate to: popularization of integrated systems, organizational measures, provision of information exchange, state financing of projects, assistance in the formation of cooperation networks, elimination of bureaucratic obstacles to cooperation, resource support for the activity of construction clusters and their participants, promoting the development of technology parks and business incubators.

The scientific novelty of the research results lies in the further development of the toolkit of the state policy of stimulating the increase in volumes and increasing the efficiency of housing construction in the country.

The applied value of the research results consists in determining the applied mechanisms and tools of state policy to improve the provision of housing for the population of Ukraine, in particular in the conditions of a full-scale war and its critically negative consequences for the social sphere and the country's system.

The article examines in detail the experience of the Iraq-Kuwait war in terms of receiving compensation for the damage caused by the war to the surrounding natural environment. In particular, the "Habitat Equivalency Analysis" methodology, which was used to determine the amount of compensatory restoration to cover losses in ecological services that were provided by natural resources before their damage. The methodology aims to estimate the total loss of services provided by a damaged or lost habitat. The FAO methodology for damage and loss assessment in agriculture was also analyzed. In which the focus is on the continuous collection of data on damage and loss in agriculture, recording the smaller and localized effects of disasters. The focus in the review of the methodology is focused on the determination of damages and losses in forestry. Such components as: damages and losses of forestry; loss of forestry production; loss of forestry products; damage to forestry assets. It was established that the considered methodology is suitable for determining the damage caused by military actions for forest resources in the part that directly concerns the forest cover.

One of the areas of damage assessment in the nature management sector is the determination of options for primary (restoration) recovery. This stage refers to actions aimed at restoring the damaged resource and, if possible, returning it to the basic level (before the war), which involves establishing recovery goals; determination of primary restoration options; selection of primary restoration options; assessment of intermediate damages, etc. The choice of primary restoration options should be the result of an evaluation process based on the following criteria, but not limited to cost of implementation; the length of time it will take for the recovery to be effective; probability of success, etc.

The next steps should be a large-scale damage assessment in accordance with generally accepted methods, development of ways to restore the natural environment and identification of funds to minimize or eliminate the damage caused to the elements of the environment or natural resources.
