Informative Value of Packaging as a Determinant of Food Purchase
Authors: Ankiel Magdalena , Grzybowska-Brzezińska Mariola
Published: July 2020

The purpose of the article is to present the concept of information value of food packaging, characterize determinants of information value and present the results of own research on the identification of key information on packaging affecting purchasing decisions of food consumers. Unit packaging constituting an inherent element of food products equipment should fulfill numerous, overlapping functions, which include: protection, transport andinformation — functional, as well as ecological and promotional. One of the priority functions of product packaging (not just food) is the informative function. It is assumed that the proper selection of information encoded on the packaging should inform the consumer exhaustively, reliably and comprehensively about the packed product, its composition, nutritional values or storage conditions. Analyzing the information included on food packaging, it can be stated that entities introducing these products onto the market still show a tendency to “excessively” label the packaging (as part of optional labeling). It is therefore reasonable to specify what information is analyzed by consumers in the purchasing process and what information constitutes the information value of unit packets from the point of view of individual consumers. The above will allow identifying key determinants of the information value of packaging and may constitute valuable information for entities introducing products to trade in the field of proper selection of characters and codes of unit packets on the food market.

Published: July 2020

The paper presents the issues of wearable technology, their role and use in the current economy. Ubiquitous digital transformation and universal access to broadband Internet are the foundation for the creation of interoperable ecosystems, where wearable technology is responsible for communication often in the relationship between machine to machine and machine to human. The authors researched the level of knowledge about these devices and the degree of their use. It turned out that despite the knowledge of worn devices and relatively positive attitudes, the degree of their use is low. The article is theoretical and empirical.
Making Concrete Pavements Competitive by Using the Standardized Framework for Comparisons of Infrastructure Projects in Terms of Cost-Efficiency and Climate Impact
Authors: Strömberg Larissa , Silfwerbrand Johan , Ansell Anders , Hintze Staffan
Published: July 2020

Despite the new Swedish client requirement to reduce the climate impact from the construction of roads, there has been relatively little research so far on how the optimization measures regarding the environmental impact of road pavements can be integrated in the traditional design. An increase in axle weights, changes of the traditional ways of travel, e.g. the use of automated and guided vehicles, and stricter customer requirements on reducing the climate impact require new approaches to steer the road and pavement industry towards more climate neutral solutions. This paper analyzes the latest standards for sustainability assessment of engineering works in an attempt to adjust these standards for assessing various road design options in a comparable and fair way, also when various materials are included.
The Relationship between Control over a Deal and Cognitive-Based Trust in an International Business Partnership
Authors: Boštjančič Eva , Ismagilova Fayruza , Maltcev Alexey
Published: July 2020

Background and purpose: Trust is embedded into the national culture. It is a tool that helps create strategic partnerships and facilitates deals that carry certain risks. Cultural differences and norms can affect business relations, but more often focus is on the obvious differences. Although trust in a business partner may be due to non-obvious differences, for example, which part of the deal the partner wants to control himself and which part of the deal he wants to give to the partner to control. If the difference between the real and desired levels of the partner’s control over the deal is large, then is trust possible, especially in intercultural business relations?

Objective: One aim of our study is to find out whether trust may be considered as moderator of control in a business deal. In other words, if the level of trust in a business partner is higher, are the partners more open to sharing their control over the deal with each other? The other aim is to identify the links between these indicators (trust and control) in business partnerships of partners from different cultures.

Design/Methodology/Approach: The study investigated the answers of 103 Slovenian and 124 Russian business partners. The Organizational Trust Inventory (OTI) and the 5-items questionnaire on control over deal were used to collect data. Descriptive and inferential statistics were used to process the data collected.

Results: The probability that the business partner will not fulfil their obligations in the deal negatively relates to the level of trust. The difference between degree of desired control and degree of control negatively relates to the level of trust.

Conclusion: As our results showed, trust cannot be considered as a strong moderator of control between partners. In response to greater trust, the respondents only agree to increase their partner’s control, but are not willing to reduce their own. Moreover, this finding is stronger in the group of Russian partners than in the Slovenian ones.
Fraud Prevention in the Leasing Industry Using the Kohonen Self-Organising Maps
Authors: Bach Mirjana Pejić , Vlahović Nikola , Pivar Jasmina
Published: July 2020

Background and Purpose: Data mining techniques are intensely used in various industries for the purpose of fraud prevention and detection. Research that focuses on the leasing industry is scarce, although frauds in the field of leasing occur rather often. First, we identify clusters of business clients in one leasing company by using the method of self-organising maps based on leasing contract attributes. Second, we compare clusters based on the presence of fraudulent clients, in order to develop fraudsters’ profiles.

Methodology: For detecting characteristics of fraudulent clients, we use a client database containing leasing contract attributes of one Croatian leasing company. In order to develop profiles of fraudulent clients, we utilise a clustering procedure with the Kohonen Self-Organizing Maps supported by Viscovery SOMine software.

Results: Five clusters were identified and labelled according to the modal values of attributes describing the leasing object and the industry in which the client operates: (i) New cars / Trade; (ii) Used trucks or tugboats / Other services; (iii) New machinery / Construction; (iv) New motors / Trade; and (v) New machinery and tractors / Agriculture.

Conclusion: Self-organising maps have proved to be a useful methodology for developing profiles of fraudulent clients in leasing companies. Companies can use our results and make additional efforts in monitoring clients from the identified industries, buying specific leasing objects. In addition, companies can apply our methodology to their own databases, in order to develop fraudster profiles for their specific purposes, and implement fraud alert mechanisms in their client database.

Published: July 2020

The article presents the results of monitoring studies on the population dynamics of goose species at one of the largest stopover sites in Northern Kazakhstan during the springs of 2011–2018. Comparative analysis of the phenological phases at the beginning and end of migration over a 50-year period is conducted and changes in timing of migration for the studied groups are established. Data on the number of flocks at various stages of the migration process are presented. Authors revealed characteristics of the distribution of birds in the directions of migration through the region associated with the presence of various migration strategies. Based on the distribution and number of geese in the region for rest and feeding, key zones with characteristics of their natural and anthropogenic state were identified. It has been established that water bodies and large areas have optimal conditions for rest and replenishment of energy reserves for the birds.

Authors: Rashid Ghulam Mustafa , Butt Abida , Qadir Abdul , Ali Mirza Habib
Published: July 2020

Diversity in avian assemblages of urban (UR), peri-urban (PE) and rural (RU) areas was studied to explore variations in the avian community dynamics in rural – urban gradient. For this purpose, sampling was done from September 2013 to August 2015. A total of 35 sites, each covering an area of 300 m2 were sampled by using point count method. At each site, randomly three points (minimally 5 m apart from each other) were selected to study the birds. According to data, species richness (F2, 32=47.18, P<0.001) varied significantly along a rural-urban gradient. A significant difference in avian density per sampling site (F2, 32=105.41, P<0.001) was also observed along urbanization gradient. In PE and RU areas, avian assemblages were more diverse than UR areas. Among avian guilds, omnivores were the most abundant in UR while insectivores in PE areas. Frugivores and carnivores were abundant in RU areas. Granivores were recorded in all habitats with similar diversity. A close association was recorded in bird density of RU and PE areas than UR areas. Bird species richness and diversity showed negative correlation with built area and positive correlation with vegetation cover in an area.
Woodcock (Scolopax rusticola L.) nestings in Carpatian Basin from the second half of the 19th century to present days
Authors: Bende Attila , László Richárd
Published: July 2020

In this study, we summarized and evaluated nesting data of 300 Woodcocks in both historic and present Hungary recorded from the 19th century until now that appeared in 108 ornithological and hunting literature including the results of Vönöczky Schenk’s study (1908–1917). We acquired a comprehensive picture of Woodcock nestings in the Carpathian Basin as we drew nesting maps based on previously collected data analysis. We classified those significant regions where nesting data of this sparsely nesting species were registered. It is ascertainable that the distribution of Woodcock nestings concentrated in certain regions of the country both before and after the First World War. Nesting data collected before 1921 concentrated to higher areas especially the well forested regions of the Carpathian Mountains where 3 main nesting regions can be distinguished with 72% of all nesting data. The most significant nesting area is the region of the North Carpathian Mountains (36%) (Pest-Pilis-Solt-Kiskun, Esztergom, Hont, Nógrád, Borsod, Gömör and Kis-Hont, Abaúj-Torna, Zólyom, Liptó, Sáros, Zemplén and Ung counties). The second main nesting region is situated on the ranges of the East and South Carpathian Mountains (26%) (Máramaros, Beszterce-Naszód, Maros-Torda, Udvarhely, Kisküküllő, Nagyküküllő, Brassó, Fogaras, Szeben, Alsó-Fehér, Torda-Aranyos counties). The third important nesting region can be found in the west part of Historic Hungary (10%) (Moson, Győr, Sopron, Vas, Zala counties). The distribution of nesting observations – based on data collected between 1921–2019 – can be connected well to mountainous nesting regions in the Kingdom of Hungary where nesting conditions were more favourable. Many of these regions are abroad now. Apart from sparse nestings on the Great Hungarian Plain, breeding grounds concentrate in well forested areas such as in North Hungarian counties (63%) (Pest, Nógrád and Borsod-Abaúj-Zemplén) and in some Transdanubian counties (31%) mainly in Győr-Moson Sopron, Vas, Veszprém and Baranya counties.

In the dominant nesting regions this species typically do not join to higher altitudes, however, in the south margin of their nesting region in the Carpathian Basin – based on 170 years nesting data (n=704) – it can be stated that they rather nest in woodlands of higher altitudes due to their more favourable (cool and rainy) climatic features.
Two Types of Verb Reduplications in Mandarin Chinese
Authors: Xie Zhu
Published: July 2020

This paper analyzes verb reduplication in Mandarin Chinese under a lexicalist framework. By adopting the Lexicalist Hypothesis proposed by Chomsky (1970), a distinction has been made between syntactic and morphological verb reduplications by means of five tests: productivity, le insertion, categorial stability, transitivity, and input/output constraints. It is found that the AA and ABAB patterns of verb reduplication have relatively high productivity and regular syntactic behaviors, whereas the AABB pattern of verb reduplication shows extremely low productivity and syntactic idiosyncrasy. Given these observations, this paper proposes that the AA and ABAB patterns should be syntactic verb reduplications derived at the syntactic level, whereas the AABB pattern should be morphological verb reduplication formed in the lexicon. The two types of verb reduplications have different generative mechanisms.

Authors: Zoričić Zdenka Obuljen , Cota Boris , Erjavec Nataša
Published: July 2020

Due to negotiations on accession to the EU, the new EU member states from Central and Eastern Europe went through the financial opening. In the pre-crisis period followed by high liquidity in global markets, most of the EU new member states experienced rapid credit growth, which conditioned the appreciation of the exchange rate. External imbalances and vulnerabilities built up. Countries experienced deterioration in their current accounts. This paper investigates the link between financial openness, real effective exchange rate, financial crisis and current account balance within the Panel Auto-Regressive Distributed Lag (ARDL) framework for 11 new European Union members during the period from 1999 to 2016. The results obtained by the use of pooled mean group estimator (PMG) show that in the long run, financial openness has a significant negative impact on the current account balance. In the short run, crisis significantly influences the current account balance having a positive sign.

Published: July 2020

Migraine is a common headache characterized by unilateral throbbing-like headache and pulsating in nature and sometimes associated with aura. Migraine is a disabling disorder that among adults is more prevalent among women than men. It is primary headache that is often found in pregnancy. Migraine is a common disorder in women of childbearing age, and usually requires pharmacological treatment. Migraine can be considered an important risk factor for hypertensive and vascular diseases during pregnancy. Migraine therapy in pregnancy is very challenging, it must taken into a consideration about the health of the mother and fetus.  Several effective antimigraine medications are reasonably safe for use by pregnant and breastfeeding women. Prophylactic theraphy should be given to patient with recurrent migraine attacks in pregnancy. Nonpharmacological strategies are always first-line treatment options for mild migraine, and should also be used complementarily whenever pharmacological treatment is required. Women with migraine should be offered periconceptional counselling to promote a safe and healthy pregnancy. Keywords: migraine; pregnancy; therapy

PERBANDINGAN EFEKTIVITAS DOSIS EKSTRAK BIJI ALPUKAT YANG DIPROSES DENGAN MILLING TERHADAP PENURUNAN KADAR GULA DARAH PADA TIKUS
Authors: Alief Clarence Marks , Manalu Jojor Lamsihar
Published: July 2020

Pendahuluan: Diabetes adalah penyakit metabolik yang disebabkan oleh pankreas yang tidak mampu memproduksi insulin (hormon yang mengatur kadar gula darah) atau tubuh yang tidak dapat menggunakan insulin secara efektif. Diabetes dapat menyebabkan gangguan penglihatan, penyakit kardiovaskuler, penyakit ginjal dan penyakit lainnya. Diabetes biasa diobati dengan obat kimia anti-diabetes atau dengan insulin. Namun saat ini, masyarakat sudah mulai mencari pengobatan alternatif yang menggunakan bahan alami. Salah satu bahan alami yang dapat dipakai sebagai pengobatan alternatif untuk diabetes adalah ekstrak biji alpukat (Persea americana Mill.). Biji alpukat dipilih karena memiliki zat aktif seperti astringen dan flavonoid yang sudah diteliti memiliki efek anti-diabetes.

Metode: Penelitian ini merupakan penelitian eksperimental menggunakan hewan uji tikus Sprague-Dawley. Kelompok tikus dibagi menjadi 4, yaitu kelompok I sebagai kelompok kontrol negatif, dan kelompok II, III dan IV. Kelompok tikus perlakuan diinjeksi dengan aloksan sehingga menginduksi kondisi diabetes, kemudian tikus diberikan ekstrak biji alpukat dengan konsentrasi berbeda setiap hari selama 5 hari. Ekstrak biji alpukat diperoleh dengan menggiling biji alpukat sehingga menjadi serbuk halus, lalu ekstraksi dilakukan dengan menggunakan metode maserasi.

Hasil: Setelah pemberian ekstrak biji alpukat, terdapat penurunan kadar gula darah pada kelompok II, III, dan IV. Hasil uji statistik one way anova menunjukkan hasil p=0,046, dengan demikian terjadi penurunan kadar gula darah yang bermakna. Namun berdasarkan hasil uji statistik Tukey HSD, kelompok uji tidak ada yang berbeda secara signifikan antara satu dan lainya.

Simpulan: Pemberian ekstrak biji alpukat (dosis of 150mg/kg, 300mg/kg, and 450mg/kg) menyebabkan penurunan kadar gula darah yang bermakna secara statistik, namun tidak terdapat dosis ekstrak yang paling efektif dari antara ketiganya.
Algunas reflexiones bogotanas sobre el conflicto armado colombiano
Authors: García-Ruiz Solángel
Published: July 2020

Nacer y vivir en un país en conflicto armado significa que este hace parte de la vida. Colombia ha atravesado ciclos de violencia de más de cincuenta años, con la firma del Acuerdo de Paz en 2016 se generó un marco de legalidad para iniciar un periodo de posconflicto en el cual la reconciliación se plantea como desafío. Ello pasa por el reconocimiento de cómo cada quien ha comprendido y vivido esa realidad. Así, usando el dibujo, la escritura y la conversación en un grupo, se indagó cómo ha sido para seis residentes en Bogotá vivir el conflicto. La reunión se convirtió en una pequeña clase de historia colectiva en la que emergió un llamado a despertar, a reconocer los propios privilegios, a asumir responsabilidades y a seguir conversando para sanar, perdonar y superar la indiferencia. Desde los saberes de las terapias ocupacionales pueden construirse alternativas y aportes a la construcción de paz en el país.

SARS-CoV-2 Nucleocapsid Assembly Inhibitors: Repurposing Antiviral and Antimicrobial Drugs Targeting Nucleocapsid-RNA Interaction
Authors: Mukherjee Debica , RAY UPASANA
Published: July 2020

SARS-CoV-2 pandemic has become a serious concern due to high transmission of this virus and unavailability of any definitive drugs yet in clinics. While novel antivirals are under investigation stage, scientists are also rigorously trying to use drug repurposing as an option to fight against this highly infectious novel coronavirus. Several drugs are under regular use for other diseases that are getting screened for their usability against SARS-CoV2. In this study we have targeted SARS-CoV-2 nucleocapsid assembly to shortlist FDA approved drugs that could be tested for inhibition of SARS-CoV-2 virus particles inside the host cell. We could shortlist five antiviral and anti-microbial drugs. These showed good fit in docking studies inside the RNA binding cleft of the nucleocapsid protein. Also, these drugs have lipophilic properties suggesting that they have the potential to enter the host cells. We propose that these shortlisted drugs could potentially compete out binding of viral RNA to nucleocapsid and thus inhibit successful virus assembly leading to poor virus progeny levels.
Traceless Click-Assisted Native Chemical Ligation Enabled by Protecting Dibenzocyclooctyne from Acid-Mediated Rearrangement with Copper(I)
Authors: Erickson Patrick , Fulcher James , Kay Michael
Published: July 2020

Chemoselective ligation reactions, such as native chemical ligation (NCL), enable the assembly of synthetic peptides into proteins. However, the scope of proteins accessible to total chemical synthesis is limited by ligation efficiency. Sterically hindered thioesters and poorly soluble peptides can undergo incomplete ligations, leading to challenging purifications with low yields. This work describes a new method, ClickAssisted NCL (CAN), which overcomes these barriers. In CAN, peptides are modified with traceless “helping hand” lysine linkers that enable addition of dibenzocyclooctyne (DBCO) and azide handles for strain-promoted alkyne-azide cycloaddition (SPAAC) reactions. This cycloaddition templates the peptides to increase their effective concentration and greatly accelerate ligation kinetics. After ligation, mild hydroxylamine treatment tracelessly removes the linkers to afford the native ligated peptide. Although DBCO is incompatible with standard Fmoc solid-phase peptide synthesis (SPPS) due to an acid-mediated rearrangement that occurs during peptide cleavage, we demonstrate that copper(I) protects DBCO from this side reaction, enabling direct production of DBCO-containing synthetic peptides. Excitingly, low concentrations of triazole-linked model peptides reacted ~1,200-fold faster than predicted for non-templated control ligations, which also accumulated many side products due to the long reaction time. Using the E. coli ribosomal subunit L32 as a model protein, we further demonstrate that the SPAAC, ligation, desulfurization, and linker cleavage steps can be performed in a one-pot fashion. CAN will be useful for overcoming ligation challenges to expand the reach of chemical protein synthesis.
Rate Coefficients and Kinetic Isotope Effects of the Cl + XCl  XCl + Cl (X=H, D, Mu) Reactions from Ring Polymer Molecular Dynamics
Authors: fang junhua , Fan Wenbin , Yang Hui , Song Jianing , Li Yongle
Published: July 2020

The ring-polymer molecular dynamics (RPMD) was used to calculate the thermal rate coefficients and kinetic isotope effects of the heavy-light-heavy abstract reaction Cl + XCl ® XCl + Cl (X=H, D, Mu). For the Cl + HCl reaction, the excellent agreement between the RPMD and experimental values provides a strong proof for the accuracy of the RPMD theory. And the RPMD results also consistent with results from other theoretical methods including improved-canonical-variational-theory and quantum dynamics. The most novel finding is there is a double peak in Cl + MuCl reaction near the transition state, leaving a free energy well. It comes from the mode softening of the reaction system at the peak of the potential energy surface. Such an explicit free energy well suggests strongly there is an observable resonance. And for the Cl + DCl reaction, the RPMD rate coefficient again gives very accurate results comparing with experimental values. The only exception is at the temperature of 312.5 K, at this temperature, results from RPMD and all other theoretical methods are close to each other but slightly lower than the experimental value, which indicates experimental or potential energy surface deficiency.

The addition of organometallic reagents to ketones constitutes one of the most straightforward synthetic approaches to tertiary alcohols. However, due to the absence of a well-behaved class of cyclopropanone surrogates accessible in enantioenriched form, such a trivial synthetic disconnection has only received very little attention in the literature for the formation of tertiary cyclopropanols. In this work, we report a simple and high-yielding synthesis 1-substituted cyclopropanols via the addition of diverse organometallic reagents to 1- phenylsulfonylcyclopropanols, acting here as in situ precursors of the corresponding cyclopropanones.The transformation is shown to be amenable to sp, sp2 or sp3 -hybridized organometallic C-nucleophiles under mild conditions, and the use of enantioenriched substrates led to highly diastereoselective additions and the formation of optically active cyclopropanols.
Análisis sobre la estandarización estadística del movimiento de carga de los puertos de Buenaventura, Buenos Aires y San Antonio entre 2010 y 2016
Authors: Gómez Pérez Cristian Mauricio
Published: July 2020

El concepto de puerto es una plataforma de intercambio de mercancías que generan utilidades a las arcas del Estado, y al mismo tiempo, generan información económica (estadísticas). Se espera que los puertos en  pro de los procesos de globalización que las últimas décadas se han venido gestando, tuvieran estandarización sobre los parámetros del movimiento de carga.

 

El presente artículo reflexivo es el resultado de la revisión de informes de los puertos de Buenaventura, Buenos Aires y San Antonio con el fin de establecer si existe o no, parámetros y estadísticas unificados que permitan realizar un análisis objetivo acerca del movimiento de carga o si por el contrario, la diversidad estadística  obliga a acudir no solo a procedimientos de conversión (TEU a TON o viceversa) sino también  la subjetividad, en cuanto a la interpretación de las cifras sobre el movimiento de carga de las plataformas de intercambio a estudiar.

 

Se desarrolla una observación de los informes  de los puertos, para determinar si realmente el movimiento de carga se encuentra unificado y/o estandarizado bajo una misma unidad de medida, se logra evidenciar que  los diferentes formatos estadísticos cuentan con  diferentes unidades de medida de la carga que impiden un análisis objetivo,  pues de por sí, dichas unidades de medición no permiten lograr la exactitud una vez convertidas ya sean de TEUS a Toneladas  y viceversa, teniendo que acudir por medio de procedimientos, a la conversión y la interpretación de  resultados  aproximados

Esta revisión teórica pretende ser un punto de partida para futuros estudios de espumas de hormigón carbonatado. El documento recoge las propiedades de las espumas de hormigón relacionadas con el aislamien-to acústico, y los tipos ambientales y las implicaciones de dos agentes espumantes (ácido cítrico y bicarbonato de sodio). Finalmente, existe una mayor eficacia del aislamiento acústico cuando la densidad está en un rango más bajo debido a la conexión entre densidad y porosidad, por otro lado, el ácido cítrico tiene vías sostenibles de producción y emisión, a diferencia del proceso de bicarbonato de sodio.

Published: July 2020

Quality Function Deployment (QFD) is a meticulous procedure of translating consumers’ needs and demands into appropriate solutions. The application of QFD has been expanded, leaving no definite boundary for its potential use, to almost every field of life. It helps   identify not only the needs and demands of a certain matter but also helps find out the solutions of those matters along with assigning them the priorities. Primary education enjoys the fundamental role and provides the foundation for further upbringing of children with respect to their educational, social, intellectual, cultural, emotional and physical proficiencies. This research article is aimed at exploring the Voices of Parents, (VOPs) (parent’s needs and demands) regarding their children’s educational requirements at primary school level. This objective is achieved by identifying significant VOPs and then converting these into Technical Solution for better and high quality of education.  With the help of QFD methodology, a real-life case study has been conducted to identify VOPS their technical solutions, then the order of these technical solutions is determined and, finally, suggestions are made about which technical solution is the most important and which one is the least. The findings provide a guide line for primary school stakeholder to identify problems and their solutions for better standard and quality of education.

KKM-PPM (Kuliah Kerja Nyata Pembelajaran Pemberdayaan Masyarakat) di desa Sawoan kecamatan Buduran bertujuan untuk meningkatkan kesejahteraan masyarakat yang sebagian besar berprofesi sebagai buruh tambak. Berbeda dengan pematang tambak yang ada di desa lain, pematang tambak di desa Sawohan lebarnya 4-8 meter. Pematang tambak tersebut dapat dimanfaatkan untuk budidaya buah-buahan. Buah mentimun emas dan buah blewah dipilih untuk dibudidayakan karena jenis buat tersebut bisa bertahan di daerah panas dan lebih baik hasilnya apabila disiram dengan air asin. Salah satu keuntungan membudidayakan mentimun emas dan blewah di pematang tambak adalah permukaan pematang tambak yang miring sangat menguntungkan sebagai aliran air hujan karena buah mentimun emas dan blewah merupakan jenis buah-buahan yang tidak tahan dengan air hujan. Untuk memberikan ketahanan mentimun emas dan blewah terhadap cuaca ekstrim di tambak dibuat green house sebagai percobaan. Sistem pengairan yang digunakan bersumber dari air sungai dengan tujuan untuk meringankan petani. Metode pelaksanaan KKN-PPM ini dimulai dengan mengundang petani berpengalaman untuk memberikan pembekalan kepada mahasiswa. Selanjutnya pelaksanaan dan praktek tanam di tambak serta memberikan pendidikan kepada warga desa dengan melalui sosialisasi dan seminar. Kemudian warga desa dimotivasi untuk dapat mempraktekkan budidaya buah-buahan di pematang tambak. Melalui kegiatan ini kesejahteraan masyarakat desa Sawohan kecamatan Buduran kabupaten Sidoarjo dapat ditingkatkan. Dari kegiatan KKN-PPM ini diperoleh model dan sistem budidaya buah-buahan di pematang tambak, keahlian warga tambak untuk budidaya buah-buahan pada pematang tambak, dan produk berupa buah-buahan yang bisa secara berkala dihasilkan oleh warga.
The system of indicators for marketing monitoring the reorganization of business structures
Authors: Sozinova Anastasia A. , Savelyeva Nadezhda K.
Published: July 2020

The hypothesis of the study is that the new context of economic liberalization and globalization is characterized by rapid, profound and complex changes in the market environment in which business structures operate. Since, in today’s economic environment, market forces are becoming the main reason for the reorganization of entrepreneurial structures and the main indicator for assessing the advisability of restructuring entrepreneurial structures. The purpose of this article is to develop a system of marketing indicators for monitoring the reorganization of business structures and practical recommendations for the implementation of this system of indicators in the economic practice of economic systems.
Statistical methods are used to identify the nature and nature of the development of marketing indicators and to determine whether there is a close relationship between marketing activities and the reorganization processes of the economic systems of modern Russia, trend and correlation analysis. Using these methods, the authors analyse the relationship between the intensity of reorganization processes and the competitiveness of the global economy, which are contained in the Russian Merger and Acquisition Market Review and the World Economic Forum.
The study concluded that the research hypothesis was fully proven. Working on the basis of official dynamic statistical information on the example of modern Russia, it has been proved that the influence of marketing indicators on the processes of reorganization of business structures is strong. In addition, the feasibility of using an evaluation tool based on marketing indicators has been reviewed on a case-by-case basis. Business systems were selected for analysis and were reorganized in 2015.
The proposed system of marketing monitoring indicators contributes to the development of the foundations of the modern marketing concept. Scientific value and novelty is represented by the developed author’s system of marketing indicators assessing the appropriateness of reorganization, as well as the results of comparative analysis of the results of the economic activity of restructured enterprises. The practical significance of the indicator system proposed by the authors lies in the establishment of an applied basis for assessing the appropriateness of reorganizing processes based on the evaluation of the marketing performance of business systems.
