Authors: Tseimakh A. Е. , Mitshenko A. N. , Kurtukov V. А. , Shoykhet Ia. N.
Published: August 2023

The article presents the results of a study of survival, markers of hemostasis, proteolysis, and tumor invasion after complex palliative treatment of patients with histologically verified malignant tumors of the bile ducts complicated by obstructive jaundice in two comparable groups of patients. The aim of the study was to evaluate the effectiveness of palliative surgical treatment using photodynamic therapy in patients with malignant tumors of the biliary system complicated by obstructive jaundice. In 10 patients of the main group, palliative surgical treatment was performed using photodynamic therapy; in 20 patients of the comparison group, palliative surgical treatment was performed without photodynamic therapy. In patients of the main group, a statistically significant increase in life expectancy by 104 days (p=0.033) was observed compared to the comparison group. At the same time, a statistically significant effect of tumor necrosis factor α, a marker of tumor invasion, on survival (p = 0.012) and a decrease in its level after photodynamic therapy by 15 pg/ml (p=0.041) was revealed. Thus, palliative treatment using photodynamic therapy of malignant tumors of the bile ducts, complicated by obstructive jaundice, can increase the survival rate of patients by reducing tumor invasion.
PROFILAXIA EM PACIENTES ESPLENECTOMIZADOS: A IMPORTÂNCIA DO BAÇO E AS POSSÍVEIS COMPLICAÇÕES DE SUA AUSÊNCIA
Authors: Rocha Sofia , Rojas Converso Thiago , Darrieux Michelle
Published: August 2023

O baço é um órgão que se localiza acima do rim esquerdo, na porção esquerda superior do abdômen; tem função imunológica e hematológica, ou seja, além de suas funções de filtragem do sangue, ele armazena células brancas do sistema imune, e a ausência desse feito, significa que o organismo estará vulnerável a micróbios. Neste sentido, a profilaxia pós esplenectomia se faz necessária para reduzir o risco de infecções severas e morte. Infelizmente, os pacientes esplenectomizados não possuem o conhecimento da importância do baço, dado que não são instruídos corretamente sobre a profilaxia dessa cirurgia. O objetivo é realizar uma revisão sobre a importância do baço e suas funções, entender os efeitos de sua ausência e a importância da profilaxia nesses casos, com propósito de obtenção de conhecimento para, assim, evitar sequelas e até mortes por conta dessa cirurgia. A metodologia utilizada foi de coleta de dados nas bases virtuais de sites que contém dissertações, artigos científicos, monografias, sites informativos e revista científica.

The Importance of The Minimum Limitation of Criminal Proof as The Implementation of The Unus Testis Nullus Testis Principle In Court
Authors: Lase Albert Michael Julyan
Published: August 2023

The main requirements in proving a criminal case must be based on valid evidence according to law and the judge's conviction on deciding a case. In the practice of the criminal justice system, there is often a lack of accuracy by judges in deciding a case, so unclear cases are still decided guilty by judges. That was only the accused's statement that proved the criminal act. What is the regulation regarding the minimum limit for proving a crime as a strength of the accused's statement as evidence of a crime in terms of the unus testis nullus testis? The imposition of decisions for perpetrators of criminal acts is regulated in Article 183 of the Criminal Procedure Code. However, there is no minimum limit for judges to consider proving a crime. Based on Article 189 (4) of the Criminal Procedure Code, the accused's statement is insufficient to prove a crime. This is because the interpretation of the article could be more precise. However, in practice, the accused's testimony has been used as the only evidence in deciding the accused's guilt in a criminal case in an Indonesian court. So, a minimum limit is needed in proving a criminal case. Criminal law as an ultimum remedium is not used arbitrarily by law enforcers and guarantees the protection of citizens' human rights as the goal of criminal law.

Authors: Alfathoni Muhammad Ilham , Lubis Cherilla Izzata Putri , Astapradja Muhammad Bijak Ramadhan
Published: August 2023

Job Loss Guarantee (JKP) is a program created by the government for workers who experienced termination of employment (PHK) with benefits in cash, job market information, and job training. Workers are still overshadowed by the uncertainty of legal protection, including JKP. JKP has been guaranteed by the Job Creation Law Act No. 11 of 2020 and then published government regulation (PP) number 37 of 2021 concerning implementing the Job Loss Guarantee program. However, the regulation of Article 20 PP No. 37 of 2021 concerning JKP explains the benefits of JKP for participants who experience layoffs are excluded from dismissals due to resignation, total permanent disability, retirement or death. This study outlines two problems: how to follow up the Job Creation Law to protect workers? and the rights of workers if they experience job loss through termination of employment?. The research method used is juridical normative. Implementing the Job Creation Law made by the government to bring a change to the JKP system is expected to be carried out in the interests of workers. Then, the government, as the controller, constantly supervises the implementation of the Job Creation Law and the National Social Security System in the field so that workers will get legal certainty.

Published: August 2023

Cuidados Paliativos (CP) consiste em uma modalidade multiprofissional onde pacientes fora de possibilidade de cura e sua família, recebem cuidados totais, ativos e integrais amparados pelo direito do paciente de morrer com dignidade. Apesar de ser uma modalidade assistencial crescente no mundo, ainda é pouco abordada na formação médica brasileira. Os objetivos do presente trabalho são discutir a importância da incorporação do tema na formação médica sob a luz da legislação vigente, a visão e o cuidado ofertado pelos CP e apresentar como sugestão uma disciplina sobre cuidados paliativos para a matriz curricular do curso de medicina. O avanço das tecnologias médicas tem prolongado e, possibilitado melhorias para a qualidade de vida da população, mesmo diante de casos de doenças graves, sem possibilidade terapêutica, incapacitantes e progressivas. A formação adequada de profissionais médicos com os recursos da paliação tem exigido que escolas médicas atendam às necessidades de saúde dos pacientes e de seus familiares. Estudantes de medicina devem ter acesso à comunicação compassiva e efetiva com pacientes, gerenciamento de dor e outros sintomas, princípios e boas práticas de cuidados paliativos. O conhecimento dos critérios para indicação de cuidados paliativos precoces e o manejo dos cuidados de fim de vida incluindo, além do controle de sintomas de sofrimento físico, a abordagem de aspectos psicossociais, espirituais e culturais dos pacientes e a identificação de riscos potenciais de luto são primordiais para a prática. Diante disso, a necessidade da inserção do ensino em CP na graduação tornou-se evidente, culminando nas publicações de Resoluções para abranger as prerrogativas previstas nas Diretrizes Curriculares Nacionais (DCNs) para o Curso de medicina. Essa discussão torna-se fundamental diante do cenário que atravessamos com a expansão de escolas médicas no país. Discute-se que uma proposta multicêntrica de disciplina transversal sobre cuidados paliativos inserida na matriz curricular do curso de medicina como um modelo factível para a sua abordagem.

The poetics of the author's situativeness in the story "The Sisters of the Cross" by A.M. Remizov
Authors: Guseva Ekaterina Vladimirovna
Published: August 2023

The article is devoted to the consideration of the poetics of the author's situativeness in the story "The Sisters of the Cross" by A. M. Remizov. Methods (historical and literary, structural, semantic) and methodological basis of the research are the works of Russian and Western scientists in the field of philology (M. M. Bakhtin, B. O. Korman, Y. M. Lotman), Russian theology (N. O. Lossky, P. A. Florensky, L. I. Shestov) and remizology (I. A. Ilyin, Greta Slobin, A.M. Gracheva, E. V. Tyryshkina, etc.). The result of the work is that the situations in the story "The Sisters of the Cross" were highlighted, their classification and a detailed analysis of the poetics of the author's situativeness by A.M. Remizov were made.    The scientific novelty of the work lies in the fact that the poetics of the author's situativeness is analyzed in detail within the framework of a global problem in the work of A.M. Remizov – the author's duality. All this allows us to conclude that the author's situativeness of A.M. Remizov is the author's individual view of the world order and man, it is a reflection of all the extra–textual factors that influenced the writer in different periods of his life and found artistic embodiment on the pages of the writer's works. The practical scope of the results of the work is seen in the possibility of using this material for deep understanding and studying such courses as "Literature of the Russian abroad", university historical and literary courses, during independent research work of students, when writing term papers and diploma projects.
PERAN NEGATIVE SOCIAL COGNITION DAN SELF-FOCUSED ATTENTION TERHADAP GEJALA GANGGUAN KECEMASAN SOSIAL PADA EMERGING ADULT DI INDONESIA
Authors: Hartanto Steffi , Priadi Mohammad Adi Ganjar , Sukmaningrum Evi
Published: August 2023

A strong fear of one or more social situations where one might be subject to criticism and scrutiny from others is a sign of social anxiety disorder. Untreated social anxiety disorder symptoms have been linked to risky conduct, including risky sexual activity, abuse of alcohol, tobacco, and other drugs, which peaks throughout the emerging adulthood stage. The key variables that contribute to the symptoms of social anxiety disorder are self-focused attention and negative social cognition, according to a number of cognitive theories. This study looked at the effects of self-focused attention and negative social cognition on social anxiety disorder symptoms in emerging adults in Indonesia. This study's design was a correlational study, and convenience sampling was used to choose participants who were between the ages of 18 and 25 and had at least a high school diploma. The Social Cognitions Questionnaire (SCQ), Self-Consciousness Scale (SCS), and Social Phobia Inventory (SPIN) were made available online to gather data. There were 124 people in all that took part in the study. The results of the multiple regression test reveal that while self-focused attention is not connected with social anxiety, negative social cognition significantly contributes to it. To research the connection between self-focused attention and symptoms of social anxiety disorder in Eastern nations, cultural factors like self-construal can be looked into.
HUBUNGAN ANTARA ADVERSE CHILDHOOD EXPERIENCE DAN SELF-CRITICISM PADA INDIVIDU DEWASA MUDA DENGAN ATTACHMENT STYLE SEBAGAI MODERASI
Authors: Purnomo Valerie , Lukita Dewi Zahrasari
Published: August 2023

Self-evaluation evolves because of all the experiences they have; experiences can alter selfevaluation. Indonesian children may encounter developmental disruption in the form of Adverse Childhood Experiences (ACE), leading to increased self-criticism and negative self-assessment. On the other hand, there are various protective characteristics against adverse childhood experiences, one of which is attachment styles, which urge researchers to perform study on the association between ACE and self-criticism mediated by attachment styles in early adult individuals. The ACE Questionnaire, Levels of Self-Criticism, and Relationship Style Questionnaire were used to assess ACE, self-criticism, and attachment styles, which were then moderately analyzed using PROCESS. 223 participants' data (ranging from 19 to 40 years old) were gathered via digital forms. The results of the moderation calculation revealed that ACE was considerably positively connected to the level of self-criticism. Attachment styles—negative with Secure and positive with Preoccupied, Fearful, and Dismissing—have a major impact on one's level of self-criticism. Individuals who experience ACE and have an attachment style of Dismissingare more prone to experience strong Internalized Self-Criticism. Including ACE characteristics such as socioeconomic position, bullying, or peer rejection in the calculation might broaden the picture of ACE and highlight their distinct impact on self-criticism levels.

Published: August 2023

Electrochemical CO2 reduction (CO2RR) has attracted significant interest as a pathway for achieving a carbon-neutral society. However, conventional gas-phase CO2 electrolysis configurations suffer from low CO2 utilization and expensive integration with carbon capture. Here, we demonstrate experimentally how a bipolar membrane (BPM) membrane electrode assembly (MEA) electrolysis cell can convert CO2 released from carbon capture solutions (K2CO3) directly into ethylene (C2H4). Using an optimized Cu-Ag electrocatalyst we demonstrate the conversion of CO2 to C2H4 with a 10% Faradaic efficiency (with a partial current density of 10 mA cm-2). During all tests, the BPM-MEA electrolysis cell also achieved ~100% CO2 utilization efficiency over 24 hours. Additionally, we discuss the impact of the cost of electricity and water loss play on the economic feasibility of BPM-MEA systems.
Hammett Structural Relationships Revealed in Chalcogen Bonded Co-crystals of Electron Rich Pyridines with 4′-Substituted Ebselen Derivatives
Authors: Fellowes Thomas , Lee Eric , Tran Jennifer , Xu Ruyi , Barber Alec , Brydon Samuel , Clegg Jack , White Jonathan
Published: August 2023

In this work, a detailed Hammett structure-structure correlation was applied to a range of chalcogen bonded co-crystals prepared by combining 4′-substituted derivatives of the selenium-based drug ebselen with three different 4-amino-substituted pyridine based chalcogen bond acceptors of differing basicities. This established that the N · · · Se chalcogen bond distance is well within the sum of the van der Waals radii of Se and N and is sensitive to the electronic nature of the substituent. Thus N · · · Se distances ranging from 2.2424(5)–2.4496(9) Å were observed with the shorter distances being observed in co-crystals of ebselen substituted with electron withdrawing groups. Associated with trends of the N · · · Se distance as a function of the 4′-substituent was lengthening of the internal Se−N bond distance consistent with a significant covalent contribution to N · · · Se chalcogen bonding in these derivatives. We define a covalency quotient for the chalcogen bond as the negative slope of the plot of the internal Se−N bond distance vs the external N · · · Se chalcogen bond distance. A value of 0.31 was obtained implying a significant covalent contribution to N · · · Se chalcogen bond. A similar result was obtained by an analysis of chalcogen bonded selenium containing molecules harvested from the Cambridge Crystallographic Database. The covalency quotient is extended to the general case for sigma-hole interactions including halogen bonding and hydrogen bonding, and we show that the covalent component of such interactions can be inferred from the lengthening of the donor bond. The degree of charge transfer in a smaller number of chalcogen bonded co-crystals of ebselen was established by measuring experimental electron density using high-resolution x-ray diffraction to more accurately measure the degree of electron transfer and hence covalency. This showed that in the most strongly bound systems, up to 1 electron worth of charge is transferred from the Lewis base to the Ch-bond donor, which again clearly points to significant covalent character.
Dependence of the structure and properties of Ba6Co6O15+δCl on the starting materials
Authors: Walensky Seth , Ni Danrui , Cava Robert
Published: August 2023

Structural refinements of Ba6Co6O15+δCl prepared using two different sources of barium oxide reveals that two different values of δ, 0.574(3) and 0.914(8), are obtained on synthesis at the same temperature in air. The refinements are based on powder X-ray diffraction data obtained with high intensity synchrotron radiation, performed to increase the sensitivity of the refinements to the oxygen contents. The magnetic and electronic properties of the materials, measured and reported here, support the differences in formula and structure but are not changed dramatically by the change in oxygen content.
Iron-Catalyzed Enantioselective Multicomponent Cross-Couplings of alpha-Boryl Radicals
Authors: Youshaw Cassandra , Yang Ming-Hsiu , Achyut Gogoi , Rentería-Gómez Angel , Liu Lei , Morehead Lukas , Gutierrez Osvaldo
Published: August 2023

Despite recent interest in the development of iron-catalyzed transformations, methods that use iron-based catalysts capable of controlling enantioselectivity in carbon-carbon cross-couplings are underdeveloped. Herein, we report a practical and simple protocol that uses commercially available and expensive iron salts in combination with chiral bisphosphine ligands to enable thåe regio- and enantioselective (up to 91:9) multicomponent cross-coupling of vinyl boronates, (fluoro)alkyl halides, and Grignard reagents. Preliminary mechanistic studies are consistent with rapid formation of α-boryl radical followed by reversible radical addition to mono-aryl bisphosphine-Fe(II) and subsequent enantioselective inner-sphere reductive elimination. From a broader perspective, this work provides a blueprint to develop asymmetric Fe-catalyzed multicomponent cross-couplings via the use of alkenes as lynchpins to translocate alkyl radicals, modify their steric and electronic properties, and induce stereocontrol.
Probing degradation in lithium-ion batteries with on-chip electrochemistry-mass spectrometry
Authors: Thornton Daisy , Davies Bethan , Scott Soren , Aguadero Ainara , Ryan Mary , Stephens Ifan
Published: August 2023

The rapid uptake of lithium-ion batteries (LIBs) for large scale electric vehicle and energy storage applications requires a deeper understanding of the degradation mechanisms that contribute to fading performance. Capacity fade has been attributed to a variety of complex and interlinking degradation mechanisms such as phase transitions, electrolyte decomposition and transition metal dissolution. These parasitic reactions are still poorly understood, however many of them evolve gases as a side product. Here we present a novel cell design that enables ultra-sensitive, fully quantified and time resolved detection of volatile species evolving from an operating LIB with on-chip electrochemistry mass spectrometry. The technique’s electrochemical performance and mass transport is described by a finite element model and then experimentally used to demonstrate the variety of new insight into LIB performance it is able to provide. Oxygen is observed to evolve from a LiNiMnCoO2 cathode, and the ensuing electrolyte degradation caused by the oxygen release is monitored. The solid electrolyte interphase reaction on graphite is monitored here too, in a variety of electrolyte systems, enabling the deconvolution of lithium consuming parasitic reactions. Finally, the improved time resolution from the novel technique reveals the first direct evidence of electrocatalytic carbon dioxide reduction to ethylene in a LIB. This finding not only elucidates the role of any evolved CO2 on LIB degradation but also provides a new avenue for fundamental understanding of a much sought-after electrochemical reaction. The emerging insight gained through the use of this novel characterisation technique may be used to guide and validate battery lifetime models, as well as inform the development of ageing mitigation strategies, facilitating the commercialisation of better batteries with longer lifetimes.

Authors: Browne Ericka Souza , Pereira Marcos , Barreto Ana , Zeppelini Caio Graco , Oliveira Daiana de , Costa Federico
Published: August 2023

Objective.

To describe the prevalence of leptospirosis in the Americas.

Methods.

A systematic review and meta-analysis, in the period 1930 to 2017, performed on a search of six platforms: PubMed, Web of Science, Scopus, Lilacs, Embase, and Cochrane.

Results.

The search found 77 publications of which 53 (68%) were from the period 2000–2017. Of the 77, 62 studies were included in the analysis, from North America (11, 17%), Central America (9, 14%), and South America (42, 67%), and 22 studies were from urban areas. Leptospirosis prevalence in the 62 studies analyzed corresponded to 28% (95% CI [23, 32]). Countries with higher prevalence were United States of America (41%), Colombia (29%), and Brazil (21%). The most frequent serovars found were Icterohaemorrhagiae (43 of 77 publications, 55%), Canicola (35, 45%), Pomona (28, 36%), and Grippotyphosa (26, 33%).

Conclusions.

There is variability of Leptospira species and serovars with heterogenous distribution throughout the Americas, with high prevalence in some countries, highlighting the need for action to control the disease.
A COVID-19 vaccination program for high-risk children aged 12–17 years in Curacao
Authors: Janssen Lindy J.F. , Lo-A-Njoe Shirley M. , ten Pas Charlotte , Duits Ashley J.
Published: August 2023

Objective.

This study aimed to describe and critically evaluate the COVID-19 vaccination program for high-risk children in Curacao and provide information about important factors such as parents’ vaccination hesitancy and effective strategies for communicating and delivering information about vaccination.

Methods.

This was a cross-sectional study. It was important to identify children aged 12–17 years who were at high risk of severe COVID-19 infection because of the limited medical facilities on the island; children considered to be at high risk were those with diseases such as obesity, hypertension or diabetes mellitus type 2. These children or their caregivers were invited by their pediatricians to be vaccinated as part of a program run by the Public Health Department of Curacao. These high-risk patients were vaccinated between 30 May 2021 and 25 February 2022 in designated child-friendly spaces, with a pediatrician present for guidance and reassurance. Children received the Pfizer-BioNTech COVID-19 vaccine at the recommended dose for their age. The primary outcome was a description and evaluation of the attendance for vaccination. The secondary outcomes were side effects after vaccination for the age groups 12–15 years and 16–17 years. Reasons for refusal or nonadherence were also registered.

Results.

Altogether 51% (24/47) of those aged 16–17 years who were invited were vaccinated compared with 42% (26/69) of those aged 12–15 years who were invited. Altogether, 46% of these high-risk children were vaccinated compared with 48% of children aged 12–17 years without risk factors. In our population, most patients did not experience any side effects and if they did, the side effects were mild. No cases of myocarditis or pericarditis were observed. A lack of trust in the vaccine and a lack of prioritization of vaccination when scheduling daily activities were important factors in refusal and nonadherence.

Conclusions.

To organize a successful vaccination program in a small community with limited resources for treating high-risk children it is crucial for medical professionals to provide reliable information. Public health initiatives should focus on assuaging parents’ fears about vaccines. In addition, ensuring there is good cooperation between doctors and the Public Health Department can help to make implementation successful.

Предмет: Экономическое значение континентальности российской территории. Цель: Выявление предпосылок формирования органически единой континентальной экономики России, имеющей центр тяжести внутри страны. Задачи: Обосновать, что континентальность территории России, с одной стороны, выступает фактором ее экономической уязвимости, а с другой – заключает в себе потенциал экономического развития. Объект исследования: Российская экономика как континентальное (материковое) хозяйство. Методология: В исследовании использованы методы историко-экономического анализа, теории производственно-технологической сбалансированности экономики, системной парадигмы, эволюционно-институциональной теории, экспертных и аналитических оценок. Результаты: События последнего времени ясно показали опасность экономической взаимозависимости, вследствие которой Россия стала жертвой ограничительных мер со стороны недружественных стран. Континентальность российской территории несет в себе идею хозяйственной самодостаточности, возможности завершения в пределах географического мира России основных процессов экономического обмена. Однако, поскольку экономическое самоутверждение никогда не достигнет своей полной завершенности, то в определенной степени останется место океаническому принципу связи с мировым рынком. Выводы. В своем экономическом развитии Россия уже идет к созданию новой мощной промышленности, ориентированной на удовлетворение внутренних потребностей, и к интенсификации своего сельского хозяйства. Транспортная необеспеченность континентальных областей не позволяет рассчитывать на мировой рынок и побуждает создавать новые центры производства ранее импортированных продуктов. Это, в свою очередь, расширит основу и будет способствовать внутриматериковой консолидации, интенсивному использованию принципа "континентальных соседств". Область применения результатов. Полученные результаты могут быть использованы при корректировке приоритетов и направлений пространственного развития России, ее внутренней и внешней экономической политики.
СРАВНИТЕЛЬНЫЙ АНАЛИЗ РАЗВИТИЯ ЖИЛИЩНОГО СТРОИТЕЛЬСТВА В 15 РЕСПУБЛИКАХ СССР В 1940–1980-Х ГОДАХ (ЧАСТЬ I)
Authors: Пилипенко Игорь Валерьевич
Published: August 2023

В статье рассматривается проблема сравнения динамики и результатов жилищного строительства в 15 республиках СССР за 45-летний период, которой в российской научной литературе до недавнего времени уделялось мало внимания. На основе составленной автором базы данных по более чем 120 союзным и республиканским статистическим сборникам предлагается авторский метод сравнения, включающий расчет 89 показателей, характеризующих ввод жилых домов по республиках, в городских поселениях и в сельской местности, по источникам финансирования (государство, население, жилищно-строительные кооперативы и колхозы), размер жилищного фонда в городских поселениях и сельской местности; динамику построенных квартир/домов; число жителей, улучшивших свои жилищные условия. В первой части статьи приводятся общие результаты расчетов по республикам, а также рейтинги РСФСР с выделением случаев вхождения республики в тройку лучших по 89 показателям. Во второй части статьи представлены результаты вычислений индикаторов для 14 остальных союзных республик.

Целью статьи является представление гипотетического императива значимости системного подхода при применении сценарного анализа для разработки и исполнения национальной программы технологического предвидения. Базу исследования составили методы системного подхода, диалектического анализа и интуитивной логики, как общенаучные методы изучения явлений жизнеспособности экономической системы и сценарного подхода (метод дерева целей) в ее технологическом развитии, также идентифицируются методы контент-анализа документов, вторичного анализа результатов эмпирических исследований, сравнительно-аналитический метод. В работе рассмотрены теоретические и методологические аспекты сценарного анализа для развития экономической системы и институциональной поддержки передовых производственных технологий в интересах государства, науки, бизнеса и социальной сферы. Представлено исследование методики строительства архитектуры «дерева целей» – последовательность декомпозиции миссии развития экономической системы посредством представления иерархии детализированных целей более низкого уровня. В механизме технологического предвидения выделены этапы формирования дерева целей в процессе разработки сценарного подхода построения иерархической организационной структуры управления и реализации Федеральной программы технологического предвидения. Полученные в статье выводы позволили определить, что в условиях внешних шоков мировые ведущие транснациональные корпорации за счет конкурентных преимуществ технологических инноваций в условиях цифровизации экономики контролируют стратегически важные сферы. Применение методологии сценарного анализа позволяет определить ключевые направления и мотивирует реализацию институциональной иерархии организационной структуры управления и Федеральной программы технологического предвидения в России.

Цель работы. В современных условиях поддержка инновационной активности, особенно в промышленности, должна стать главным приоритетом в политике регионального правительства. Но для этого необходимо определение четких стратегических целей и ориентиров будущего экономики, концентрации имеющегося интеллектуального капитала, а также методов достижения поставленных задач. Метод или методология проведения работы. В статье проводится анализ динамики доли обрабатывающих производств, доли высокотехнологичных и наукоемких отраслей за последние 15 лет, а также объема инновационных товаров, работ, услуг в процентах от общего объема отгруженных товаров, выполненных работ, услуг в России и Республике Дагестан. Результаты. При формировании промышленной политики региона на инновационной основе она может и должна иметь свои особенности, и данные особенности необходимо учитывать, в первую очередь, при формировании и реализации долгосрочных целей, приоритетов, задач и конкретных проектов развития промышленности, что должно быть обозначено и в законе о промышленной политике региона и в стратегии его социально-экономического развития. Выводы. Каждый регион, а в данной статье мы рассматривали пример Республики Дагестан, должен сделать свой выбор, какую модель промышленной политики применить. Выбор модели, конечно же, должен зависеть от общего состояния экономики, особенностей социально-экономического развития региона, наличия производственного, технологического, трудового, природного, научного потенциалов, а также уровня их использования, исторически сложившейся специализации региона и его места во внутрироссийском и международном разделении труда, а также, что немаловажно, менталитета и традиций местного населения.
