Authors: Hapsari Roro Endah Dwi Putri , Nurhayati Dies
Published: November 2023

Peningkatan kesejahteraan penduduk dapat dipicu oleh perkembangan ekonomi. Salah satu faktor yang memiliki dampak pada pertumbuhan ekonomi suatu negara adalah aktivitas perdagangan lintas negara. Selain produk kaca, produk hasil laut juga menjadi salah barang dengan permintaan cukup tinggi di pasar internasional. Ragam hasil laut Indonesia memiliki kualitas baik yang membuat hasil laut banyak diminati untuk ekspor, salah satunya adalah hasil udang vaname yang ada di wilayah Jawa Timur. Penelitian ini bertujuan untuk menganalisis bagaimana perdagangan internasional, khususnya ekspor hasil laut seperti udang vannamei, berkontribusi terhadap pertumbuhan ekonomi Indonesia. Metode penelitian yang digunakan adalah kualitatif-deskriptif. Hasil penelitian ini menunjukkan bahwa perdagangan internasional, khususnya melalui ekspor produk seperti udang vannamei dan hasil laut lainnya, telah memberikan kontribusi yang signifikan terhadap pertumbuhan ekonomi. Ekspor tersebut telah memberikan devisa negara, menciptakan lapangan kerja, dan mendorong berkembangnya sektor-sektor terkait. Namun, tantangan seperti fluktuasi harga internasional dan ketergantungan pada satu komoditas ekspor perlu diatasi melalui peningkatan diversifikasi ekonomi.

Published: November 2023

Background: Neuropsychiatric symptoms (NPS) carry an increased risk of progression from mild cognitive impairment (MCI) to Alzheimer’s disease (AD). There is a need to understand how to integrate NPS into the paradigm outlined in the 2018 NIA-AA Research Framework. Objective: To evaluate a prediction model of MCI-AD progression using a collection of variables, including NPS, cognitive testing, apolipoprotein E4 status (APOE4), imaging and laboratory AD biomarkers. Methods: Of 300 elderly subjects, 219 had stable MCI and 81 MCI-AD progression over a 5-year follow-up. NPS were measured using the Neuropsychiatric Inventory (NPI). A multivariate Cox Proportional Hazards Regression Analysis assessed the effects of APOE4, baseline NPI, baseline CSF amyloid-β, phosphorylated and total tau, baseline AD-signature MRI biomarker, baseline memory and executive function on MCI-AD progression. Results: 27% progressed to dementia (median follow-up = 43 months). NPS were found in stable MCI (62.6%) and MCI-AD converters (70.3%). The Cox model exhibited a good fit (p < 0.001), and NPS (HR = 1.033, p = 0.027), phosphorylated tau (HR = 1.011, p = 0.025), total tau (HR = 1.005, p = 0.024), AD-signature MRI biomarker (HR = 0.111, p = 0.002), executive function (HR = 0.727, p = 0.045), and memory performance (HR = 0.387, p < 0.001) were significantly associated with dementia. Conclusions: NPS may inform dementia risk assessment in conjunction with cognitive testing and imaging and laboratory AD biomarkers. NPS is independently associated with the risk of MCI-dementia progression, over and beyond the contributions of CSF biomarkers.
Sex and Sleep Disruption as Contributing Factors in Alzheimer’s Disease
Authors: Johnson Carrie E. , Duncan Marilyn J. , Murphy M. Paul
Published: November 2023

Alzheimer’s disease (AD) affects more women than men, with women throughout the menopausal transition potentially being the most under researched and at-risk group. Sleep disruptions, which are an established risk factor for AD, increase in prevalence with normal aging and are exacerbated in women during menopause. Sex differences showing more disrupted sleep patterns and increased AD pathology in women and female animal models have been established in literature, with much emphasis placed on loss of circulating gonadal hormones with age. Interestingly, increases in gonadotropins such as follicle stimulating hormone are emerging to be a major contributor to AD pathogenesis and may also play a role in sleep disruption, perhaps in combination with other lesser studied hormones. Several sleep influencing regions of the brain appear to be affected early in AD progression and some may exhibit sexual dimorphisms that may contribute to increased sleep disruptions in women with age. Additionally, some of the most common sleep disorders, as well as multiple health conditions that impair sleep quality, are more prevalent and more severe in women. These conditions are often comorbid with AD and have bi-directional relationships that contribute synergistically to cognitive decline and neuropathology. The association during aging of increased sleep disruption and sleep disorders, dramatic hormonal changes during and after menopause, and increased AD pathology may be interacting and contributing factors that lead to the increased number of women living with AD.
S1PR2 Regulates Autophagy Through the AKT/mTOR Pathway to Promote Pathological Damage in Alzheimer’s Disease
Authors: Wang Xiaoping , Huang Rui , Huang Bin , Li Xiaojia
Published: November 2023

Background: Alzheimer’s disease (AD) is a fatal and debilitating neurodegenerative disease. Sphingosine-1-phosphate receptor 2 (S1PR2), one of the receptors of S1P, is a key regulatory factor for various diseases. Objective: This study aimed to explore the role and possible mechanism of S1PR2 in AD. Methods: S1PR2 expression in the AD mice was detected, and after intervening S1PR2 expression with sh-S1PR2 in AD mice, the behavioral changes, pathological lesions of the hippocampus, autophagy level, and AKT/mTOR pathway activation were analyzed. Furthermore, SH-SY5Y cells were induced by Aβ25-35 to construct an AD cell model, and the effects of sh-S1PR2 on proliferation, apoptosis, autophagy, and AKT/mTOR pathway of AD cells were investigated. In addition, the effects of pathway inhibitor rapamycin on model cells were further analyzed. Results: The expression of S1PR2 was significantly increased in AD mice, the sh-S1PR2 significantly improved behavioral dysfunction, alleviated pathological injury of the hippocampus, increased the number of neurons, and inhibited Aβ production and p-tau expression, showing a positive effect on the AD pathology. In addition, silencing of S1PR2 expression significantly promoted the autophagy level and inhibited the activation of the AKT/mTOR pathway in AD model mice. In vitro experiments further confirmed that sh-S1PR2 promoted cell proliferation, inhibited apoptosis, relieved cytopathology, promoted autophagy, and inhibited the activation of the AKT/mTOR pathway in the cell model. The use of rapamycin further confirmed the role of AKT/mTOR pathway-mediated autophagy in the regulation of AD by S1PR2. Conclusion: S1PR2 promoted AD pathogenesis by inhibiting autophagy through the activation of AKT/mTOR pathway.

Background: There is a need for clinical quality indicators (CQIs) that can be applied to dementia quality registries to monitor care outcomes for people with Alzheimer’s disease and other forms of dementia. Objective: To develop tertiary and primary care-based dementia CQIs for application to clinical registries for individuals with dementia accessing aged care services and determine 1) annual trends in CQI incidence between 2011–2012 and 2015–2016, 2) associated factors, and 3) geographic and facility variation in CQI incidence. Methods: This retrospective repeated cross-sectional study included non-Indigenous individuals aged 65–105 years who lived with dementia between July 2008-June 2016, were assessed for government-funded aged care services, and resided in New South Wales or Victoria (n = 180,675). Poisson or negative binomial regression models estimated trends in annual CQI incidence and associated factors. Funnel plots examined CQI variation. Results: Between 2011–2012 and 2015–2016, CQI incidence increased for falls (11.0% to 13.9%, adjusted incidence rate ratio (aIRR) 1.05 (95% CI 1.01–1.06)) and delirium (4.7% to 6.7%, aIRR 1.09 (95% CI 1.07–1.10)), decreased for unplanned hospitalizations (28.7% to 27.9%, aIRR 0.99 (95% CI 0.98–0.99)) and remained steady for fracture (6.2% to 6.5%, aIRR 1.01 (95% CI 0.99–1.01)) and pressure injuries (0.5% to 0.4%, aIRR 0.99 (95% CI 0.96–1.02)). Being male, older, having more comorbidities and living in a major city were associated with higher CQI incidence. Considerable geographical and facility variation was observed for unplanned hospitalizations and delirium CQIs. Conclusions: The CQI results highlighted considerable morbidity. The CQIs tested should be considered for application in clinical quality registries to monitor dementia care quality.

Published: November 2023

Background: Alzheimer’s disease (AD) stands as the prevailing type of dementia, marked by gradual memory loss and cognitive decline. Transcranial direct current stimulation (tDCS) is a non-invasive method used to regulate cortical brain function and has been explored as a potential treatment for cognitive impairment. Objective: This study aimed to compare the effects of daily home-based active or sham tDCS on cognitive function in patients with early-stage AD and its follow-up after one month. Methods: The study involved a randomized, blinded, and controlled-placebo design, with 18 participants enrolled. The primary outcome measures were general cognitive function, immediate, and delayed recall, and executive function. Participants included in the study were randomly assigned to the anodal and sham tDCS groups. Participants were assessed before and after the intervention and one month after the end of treatment. The home-based intervention was applied for 5 consecutive days, daily. Results: The results showed a significant interaction between the active and sham groups; in particular, improvements in MMSE scores, immediate memory and delayed recall were observed at one-month follow-up in the active group. Conclusions: The positive effects of tDCS on cognitive function in AD patients observed suggest that tDCS may induce long-term neuroplastic changes, leading to sustained improvements in cognitive abilities.

Authors: Zhang Xinghao , Wu Pengfei , Zhao Yue
Published: November 2023

The potential link between COVID-19 and Alzheimer’s disease (AD) has been an intriguing topic in the global pandemic. Whether the susceptibility and severity of COVID-19 affects the onset and progression of AD is of great concern. Clinical studies suggested an increased risk of AD occurrence or cognitive deficit after COVID-19. Basic research found that severe COVID-19 induced changes resembling AD. Evidence synthesis should always take into account diverse study designs, both traditional and novel. The recent study by Ding et al. aimed to investigate the association of COVID-19 with AD using a non-overlapping two-sample Mendelian randomization analysis.

Authors: Jia Wanjun , Li Changyong
Published: November 2023

This study proposes a method to help people with different degrees of hearing impairment to better integrate into society and perform more convenient human-to-human and human-to-robot sign language interaction through computer vision. Traditional sign language recognition methods make it challenging to get good results on scenes with backgrounds close to skin color, background clutter, and partial occlusion. In order to realize faster real-time display, by comparing standard single-target recognition algorithms, we choose the best effect YOLOv8 model, and based on this, we propose a lighter and more accurate SLR-YOLO network model that improves YOLOv8. Firstly, the SPPF module is replaced with RFB module in the backbone network to enhance the feature extraction capability of the network; secondly, in the neck, BiFPN is used to enhance the feature fusion of the network, and the Ghost module is added to make the network lighter; lastly, in order to introduce partial masking during the training process and to improve the data generalization capability, Mixup, Random Erasing and Cutout three data enhancement methods are compared, and finally the Cutout method is selected. The accuracy of the improved SLR-YOLO model on the validation sets of the American Sign Language Letters Dataset and Bengali Sign Language Alphabet Dataset is 90.6% and 98.5%, respectively. Compared with the performance of the original YOLOv8, the accuracy of both is improved by 1.3 percentage points, the amount of parameters is reduced by 11.31%, and FLOPs are reduced by 11.58%.

Published: November 2023

BACKGROUND: Students with intellectual and developmental disabilities lag behind their peers without disabilities when it comes to participation in college and employment. In response to this, researchers at Virginia Commonwealth University (VCU) created an online, six-week course for staff who work with students with disabilities in inclusive postsecondary education (IPSE) programs. OBJECTIVE: To create a course and technical assistance (TA) based on implementing supported employment strategies through VCU’s ACE-IT in College model, using evidence-based employment practices. The course and TA were developed to increase the skills of IPSE program staff, as well as increase the number of paid internship opportunities for the students in their programs. METHODS: VCU staff offered a six-week training program, followed by yearlong technical assistance to college and university staff who implement inclusive postsecondary education programs. The researchers conducted a case study of one program and followed them through the course and their TA activities. Data examined were: facilitated discussion board responses, needs assessment results, meeting notes and case study notes, as well as goals and strategies they developed. RESULTS: Results indicate a need for more staff and funding, as well as university buy-in. The fidelity of implementation allowed researchers to make slight adjustments for future TA participants. CONCLUSION: One participating program emerged as a case study site, and results indicate a need for more staff and funding. Detailed descriptions and technical assistant support strategies are provided, as well as implications for further research.

Depending on their anatomical site and size, the lesions can cause a variety of aesthetic and functional deficits. Several treatment options are available, the most suitable is still under debate. The experience gained at our Centre and the review of the literature can be useful to improve prenatal counseling, that is challenging due to the heterogeneity of clinical presentation and treatment.
Investigation of forming of structural components of iron ore sinter of different basicity under heating
Authors: VYAZNIKOVA E. A. , Dmitriev A. N. , Vit’kina G. Yu. , Vedmid’ L. B.
Published: November 2023

A high-quality iron ore sinter must have sufficient mechanical strength both in the cold and hot state. Structural components such as the binding phases of calcium and aluminum silicoferrites SFCA and modifications of dicalcium silicate directly affect the strength characteristics of the sinter. During phase transitions, the volume of phases changes, which leads to the occurrence of stresses at the phase boundaries. Then stabilized phases of SFCA are key bundles in the iron ore sinter. Understanding the mechanisms of SFCA formation can lead to an increase in the efficiency of sintering process. The phase transformations occurring in sinter with a basicity of 1.2‒2.0 under controlled heating in an inert atmosphere and an air atmosphere are investigated. The temperatures of phase transitions during heating are shown. The study of the phase composition of sinter samples with different basicities showed that the ore phase consists of magnetite Fe3O4, hematite Fe2O3, calcium and aluminum silicoferrite SFCA and dicalcium silicate modifications α-2CaO•SiO2 and β-2CaO•SiO2. With an increase in the basicity of the sinter, the amount of magnetite and SFCA increases, the amount of hematite decreases, the content of α- and β-2CaO•SiO2 increases slightly. Heating of the sinter in the air atmosphere leads to the oxidation of magnetite to hematite, a decrease in the amount of SFCA, an increase in bicalcium and the appearance of tricalcium silicate. Heating in an inert atmosphere contributes to an increase in the amount of magnetite due to the reduction of hematite and the decomposition of the SFCA phase and an increase in the amount of dicalcium silicate.

Published: November 2023

In practice, it often becomes necessary in practice to identify a particular substance or chemical product as a whole, and also to quantify their content in the developed material. Corrosion inhibitors are special chemicals that retard the process of chemical and physical reactions. Determination of the minimum permissible concentration of the inhibitor in anticorrosive papers has an important practical significance because it specifies the duration of their protective effect. The possibility of practical application of infrared (IR) spectroscopy is considered in the study of structural features of volatile corrosion inhibitors and packaging materials with these inhibitors. Koring 501, Koring 505 inhibitors of Cortec Corporation (USA) and UNI inhibitor (a mixture of sodium nitrite and urotropine in a ratio of 1:1, Russia) were used as volatile corrosion inhibitors for anticorrosive packaging materials preparation. Aqueous solutions of inhibitors containing 5 % (wt.) of the active substance were applied on the surface of creped paper with thermoplastic polymer lamination on one side by roller method. IR spectra of pure inhibitors and inhibited samples of packaging material were plotted on an IR Fourier spectrometer FT 801. The IR spectra of each inhibitor exhibit peaks that are unique to it. This will allow the inhibitors to be distinguished from each other. It was found by means of IR analysis that the composition of foreign inhibitors includes compounds containing nitrite ions (NO2‒). It is shown that the IR spectroscopy can be used to control the quality of the anticorrosive packaging materials. This is particularly topical in the conditions of import substitution.

Published: November 2023

The influence of reducing metals on the metallurgical processes of thermite welding has been studied. Iron scale and powdery materials were used as starting materials for the metallothermic mixture: titanium powder PTS according to TU 15‒1958, aluminum powder PA-2 according to GOST 6058‒73. Aluminum gas purification dust was introduced into the composition of the metallothermic mixture. The chemical composition of the metal was determined by the atomic emission method using the DFS-71 spectrometer according to GOST RISO 14284‒2009, the slag composition was determined by the X-ray fluorescence method on the Shimadzu XRF-1800 spectrometer according to GOST 28033‒89. The composition of the titanothermite mixture has been developed, which ensures the production of dense metal. The addition of a small amount of aluminum powder to the composition of the titanium-thermite mixture ensures the completeness of the interaction and reduction of iron scale, at the same time, the amount of molten metal increases. The introduction of aluminum gas purification dust into the thermite mixture as a flux reduces gas emission during thermal processes. In addition, the addition of a carbon-fluorine-containing flux additive increases the carbon content in the resulting metal and improves its mechanical properties.
Designs of reinforcing ropes: history, current status and directions of development
Authors: Kharitonov V. A. , Ul’yanov S. A.
Published: November 2023

The main building material at present is concrete, strengthened by reinforcing elements of various configurations and methods of application. The most effective type of reinforcement for prestressed reinforced concrete structures is a reinforcing rope, which is reinforced in two ways: “on stop” and “on concrete”. The most important requirements for reinforcing ropes are high strength and adhesion to concrete when reinforcing “on the stop”, and a smooth surface when reinforcing “on concrete”. In the current practice of production and use of reinforcing ropes, round tempered or stabilized seven-wire ropes are most widely used. However, these ropes have a relatively low adhesion to concrete, which does not allow a higher prestress to be transferred to the concrete. The aim of the work is to determine the direction of development of production and application of reinforcing ropes based on the analysis of their structures. The analysis reveals the adhesion to concrete is determined by the design of the rope. In addition, the complexity of the manufacturing process, production costs and operating conditions depend on the design. The resistance to rope move-ment in concrete is determined by mechanical and “corkscrew” coupling, with mechanical coupling being the most ef-fective. An increase in the adhesion of the ropes was achieved by the developed surface, shaped section, and lay of wires with a periodic profile. However, these methods complicate the design, manufacturing technology and operating conditions of the rope. The most effective way to increase the adhesion of a reinforcing rope to concrete is the calibrat-ing compression of a twisted rope in a roller die with simultaneous application of a profile to the outer surfaces of the wires of the upper layer. This provides, without changing the design of the rope and the technology of its manufacture, a significant increase in the adhesion of the rope to concrete, its quality indicators and operational properties. In addition, the use of calibrating compression in a round gauge provides an increase in efficiency of reinforcing ropes for reinforcement “on concrete”.

Published: November 2023

This paper presents a novel switched-capacitor enhanced-boost quasi-Z-source inverter (SCEB-qZSI) for renewable energy applications. The described topology is a novel power electronic converter that uses switched-capacitors to increase the voltage boost. In the meanwhile, a reduced shoot-through condition results in a higher dc-link voltage. Moreover, the proposed concept has the advantages of continuous input current, smaller current ripple, common grounding, and high output voltage gain. The proposed topology is thoroughly examined, and simulation data are used to support the theoretical analysis. The proposed SCEB-qZSI topology has potential uses in electric vehicles, industrial applications, and renewable energy systems which may develop by using the inexpensive components making it an attractive option for applications that have limited funds. D represents the shoot-through duty ratio of the inverter switches which can range from 0<D<0.144. In the proposed topology inductor voltages, inductor currents, capacitor voltages, diode currents, and voltage source inverter outputs are extracted with and without filters and are discussed in brief. The theoretical and simulation evaluation for the above findings is presented in this paper.
Differentiating capabilities of papillary patterns in finger’s middle phalanges (using the example of Eurasian populations)

Published: November 2023

Introduction. An assessment of the currently known data on intergroup variability of papillary patterns of fingers' middle phalanges suggests the possibility of using these characteristics to differentiate Eurasian populations. Material and methods. The study conducted on the prints of fingers' middle phalanges of 1178 men from 12 ethno-territorial groups of Russia and Kyrgyzstan. These are mainly archival materials represented by impressions of the entire palmar surface of the hand. Therefore, we applied а classification that unites morphologically similar variants to eliminate possible errors in determining the types of skin patterns. Results. Statistically significant differences revealed when comparing the proportions of dermatoglyphic features in Caucasian populations, on the one hand, and mixed Caucasian-Mongoloid or Mongoloid populations, on the other. The occurrence frequencies of straight and hook patterns increase, and the frequencies of distal arc and complex double patterns decrease in the presence of a Mongoloid (or Uralic) component. The results of cluster analysis and multidimensional scaling confirmed the division of populations depending on the presence of a Mongoloid, including Ural, component in their racial composition. Within the main clusters, groups were differentiated according to anthropological similarity and territorial proximity. The skin patterns’ complex of digital middle phalanges is very sensitive to the presence of a Mongoloid (or Uralic) component in Caucasian populations, as well as the main dermatoglyphic features of the hand. The differentiation of samples according to the patterns of the middle phalanges largely corresponds to the division based on classical racial and key dermatoglyphic characteristics. However, as a result of multidimensional scaling, the Volga-Kama populations were located further from the Caucasoid than both Mongoloid samples. Therefore, shares’ distribution of united dermatoglyphic signs in Mongoloid populations requires clarification using additional data. Conclusion. The results of various statistical analyzes allow us to conclude that it is possible to use dermatoglyphic characteristics of digital middle phalanges to differentiate Caucasoid samples and groups with a Mongoloid (or Ural) component. The presence of the Mongoloid component in the groups is accompanied by a decrease in the complexity of the papillary patterns on the middle phalanges. @ 2023.

Introduction. In this paper, we compared patterns of longitudinal long bone growths of the Late Bronze Age population from Southern Urals, representing pastoral communities, predominantly cattle breeders, and the relatively synchronous agricultural population from Central Asia using standardized z-scores. Materials and methods. The analyzed sample comes from two cemeteries of the Srubnaya culture in Pre-Urals (Karanayevsky and Chumarovo-1), and two cemeteries of the Srubnaya-Alakul cultural type in Trans-Urals (Nepluyevsky and Yulaly-8). The comparative sample represents data from Gonur Depe, a Bronze Age proto-urban center in Southeastern Turkmenistan. The sample sizes were 32 and 56 individuals respectively, aged between 2 and 12 years old. The measurements of all six long bones and updated reference Maresh standards (mid-20th century, USA) were used to calculate z-scores. The obtained z-scores were analyzed using both parametric methods and nonparametric statistics. Results. Z-scores for the diaphyseal lengths differed significantly between the two analyzed samples. The distribution of z-scores for the Gonur Depe sample was more noticeably shifted towards lower values. In the Southern Ural sample, 6.7% of children had z-scores no lower than those in the reference group, while in the Gonur Depe sample this value constituted only 0.6%. Z-scores for the upper limb bones in both groups were significantly higher than those for the lower limb bones. In the Southern Ural sample, children under 6 years of age had significantly higher z-scores compared to 9–12-year old children. No such differences were found in the Gonur Depe sample. Discussion. The pooled Bronze Age sample from Southern Urals showed overall less stunting from the reference group compared to the Gonur Depe sample. This is consistent with the hypothesis of a smaller long bone lengths and shorter stature in agricultural compared to pastoral populations. In both groups, the lower limb bones had lower z-scores compared to the upper limb bones, indicating that growth stunting relative to the reference values is more expressed for the lower limbs.@ 2023.

OCB behavior can create a sense of employee attachment to the company so that it tends to avoid counterproductive attitudes. This study examines the effect of CWB on OCB in sales employees. The results of this causal study indicate that employees with high CWB behavior tend to have low OCB behavior and vice versa.

The urgency of the topic is due to the need to study the mechanism of the regulatory function of taxes through which the state actively influences the macroeconomic processes in conditions of economic instability. In conditions of economic ups and downs, the fiscal system, as a basic element of the economy, on the one hand, provides the financial foundation of the state, and on the other hand - is one of the main tools for tax policy and government intervention in the economic system. Taxes are an integral part of the fiscal system; they are an objectively existing institution of society, and one of the factors influencing social and economic development, which requires a study of its mission and content. The peculiarities of the regulatory function of taxes in the conditions of endogenous and exogenous factors of instability are revealed. It is shown that integration into the external uncertain financial space causes a number of non-standard problems for the national system of state regulation of the economy, in particular, the problem of choosing between the policy of nominal devaluation and the policy of fiscal devaluation. The article analyzes the quantitative criteria of tax policy and their impact on the effectiveness of the regulatory function of data in Ukraine during 2014-2022. Based on the analysis the conclusion is made about the predominantly fiscal focus of regulatory measures of modern state tax policy. To assess the limitations of the regulatory and instrumental role of taxes in performing the exclusive functions of the state in the economy and society, we described the institutional limitations of the regulatory function of taxes due to their connection with the institutional structure of the economy through the channels of economic sovereignty and legitimacy, trust and state debt. The content of institutional traps related to the deficit of tax revenues to the state budget is revealed, and it is shown that the tendency to avoid these traps is an institutional feature that limits the effect of tax instruments of state regulation of economic processes. Some ways of tax reform in Ukraine are given.

This process requires a significant array of data for making management decisions, which emphasizes the importance of information to ensure the development of the enterprise. The development of the enterprise is the goal of activity and acts as a separate object of management. The purpose of the article is to consider the content and tasks of the information management process in ensuring the development of the enterprise. In the research process, general and special methods were used, in particular: analysis and synthesis to determine the meaningful characteristics of the development of the enterprise and the information process, as well as methods of induction and deduction to clarify the parameters of the enterprise's development. By the method of system analysis, interdependencies between information and management decisions were established and a list of information process management tasks was formed to ensure the development of the enterprise. On the basis of the analysis of the dependence between the management process, information and the development of the enterprise, a scheme of the relationship between information and the management decision, which takes into account the reasons for its adoption, has been developed. The definition of enterprise development management has been clarified, in particular, attention has been focused on taking into account changes in individual elements of the system as a parameter of enterprise development. This made it possible to form management tasks within the management information process regarding the formation of the management system, support of its functioning, data interpretation, creation and observance of information work regulations, ensuring maximum compliance between material, financial and information flows. The obtained results can be used to improve the management of industrial enterprises by taking into account the recommendations regarding the functioning of the information process, namely the performance of tasks related to its regulation, the performance of mandatory tasks by personnel to ensure the construction of a clear system of formation and transmission of information messages.
