Authors: Hamidah Hamidah
Published: January 2021

ABSTRACT

        Organic farming continues to grow in line with the rapid market demand for organic fruit and vegetables. In our country, organic agriculture is experiencing rapid development due to the fact that agricultural products, especially fresh vegetables and fruit, are grown using organic farming systems. Organic agricultural products are starting to attract consumers, especially the upper middle class, who are willing to pay more for food products that are healthy, safe, and environmentally friendly. The purpose of this study was to determine the use of organic fertilizers for washing rice water and pruning water shoots on the growth and yield of tomato plants. The research was conducted in Gunung Kelua village, Samarinda, East Kalimantan for approximately 4 (four) months, from March to July 2020. This study used a randomized block design arranged 3x2 factorial with 3 replications. The first factor is liquid organic fertilizer which consists of 3 (three) levels, including: P0 Without Treatment, P1 (Liquid Organic Fertilizer 250 ml / l water), P2 (Liquid Organic Fertilizer 500 ml / l water). The second factor is pruning water shoots consisting of 2 (two), namely T0 without pruning water shoots on tomato plants, T1 by pruning water shoots on tomato plants. The results showed that the application of liquid organic fertilizer had no significant effect on plant height, but had a significant effect on the number of fruits and production.
Zróżnicowanie rozwoju społeczno-gospodarczego obszarów wiejskich w województwie małopolskim
Authors: Semczuk Marcin
Published: January 2021

Za główny cel pracy przyjęto określenie zróżnicowania rozwoju społeczno-gospodarczego na obszarach wiejskich województwa małopolskiego, jak i określenie dynamiki jego zmian w przyjętym okresie. Wykorzystano dane statystyczne dla 168 wiejskich jednostek przestrzennych – gmin wiejskich oraz obszarów wiejskich gmin miejsko-wiejskich. Podstawowym źródłem danych był Główny Urząd Statystyczny (dla lat 2002–2017) oraz Urząd Komunikacji Elektronicznej (dla roku 2017). Pozyskane dane posłużyły do obliczenia wskaźnika syntetycznego rozwoju społeczno-gospodarczego dla obszarów wiejskich, który składa się z następujących grup wskaźników: społecznych, demograficznych, rynku pracy, sektora rolniczego, warunków mieszkaniowych i infrastruktury. Łącznie, na potrzeby analizy, wykorzystano dwadzieścia sześć wskaźników. Stały się one podstawą do określenia obszarów wiejskich charakteryzujących się najwyższym poziomem rozwoju, tych będące na etapie stagnacji oraz jednostek wyróżniających się regresem społeczno-gospodarczego. Jednocześnie zbadano dla analizowanego obszaru, dynamikę poszczególnych grup określając cztery typy jednostek, uwzględniając relację wartości danych grup wskaźników i ich dynamikę w przyjętym okresie. Z przeprowadzonej analizy wynika, że narastają dysproporcje pomiędzy gminami bardzo słabo i bardzo wysoko rozwiniętymi gospodarczo, zwłaszcza w zakresie wskaźników opisujących rynek pracy. Jednocześnie widać zmniejszanie dysproporcji rozwojowych wśród wskaźników opisujących cechy demograficzne, jak i warunki mieszkaniowe.
Zmiany przyrostu naturalnego i salda migracji w gminach wiejskich Miejskich Obszarów Funkcjonalnych w Polsce w latach 2002–2017
Authors: Serafin Piotr
Published: January 2021

Procesy demograficzne w warunkach stabilnej gospodarki z reguły odznaczają się wolnym przebiegiem. Obecny stan i struktura ludności Polski jest konsekwencją przeszłych oraz zachodzących obecnie procesów demograficznych (m.in. zmian w ruchu naturalnym, migracji, wydłużania życia), ekonomicznych (m.in. dostępu do rynku pracy, usług, mieszkania) jak i społeczno-kulturowych (m.in. zmiany wzorców prokreacyjnych, bogacenia się społeczeństwa). Cechą wyróżniającą obecne zmiany ludnościowe w Polsce jest zmniejszanie się liczby Polaków. Niekorzystną sytuację potwierdzają: postępujący proces starzenia ludności, depopulacja obszarów wiejskich oraz znaczącej liczby miast. Za cel przyjęto określenie kierunków zachodzących zmian w zaludnieniu, ruchu naturalnym i migracjach ludności mieszkającej w gminach wiejskich, położonych w Miejskich Obszarach Funkcjonalnych wyznaczonych dla miast wojewódzkich. Badaniami objęte zostały gminy wiejskie należące do 18-tu Miejskich Obszarów Funkcjonalnych (MOF) ośrodków wojewódzkich, wyznaczonych przez prof. P. Śleszyńskiego. Analizą czasową objęto lata 2002–2017. W badaniu posłużono się metodą typów rozwoju ludnościowego Webba, która pozwala określić relacje między przyrostem naturalnym i saldem migracji. Przeprowadzone grupowanie wykazało, iż obecnie szczególnie ważnym czynnikiem rzutującym na liczebność mieszkańców w większości gmin wiejskich skupionych wokół rdzenia, jest notowane dodatnie saldo migracji, przeważające nad dodatnim przyrostem naturalnym. Charakterystyczną cechą badanych obszarów jest także znaczne ich wewnętrzne zróżnicowanie przestrzenne pod względem analizowanych wskaźników ludnościowych, jak i składowych przyrostu rzeczywistego, co będzie warunkować odmiennie przebiegające w nich procesy rozwojowe w przyszłości.
Wpływ podnoszenia mrozowego na infrastrukturę drogową na północ od Krakowa oraz możliwości przeciwdziałania
Authors: Augustowski Karol
Published: January 2021

Procesy mrozowe odgrywają dużą rolę w przekształcaniu powierzchni drogowej zarówno na obszarach wiejskich, jak i w miastach. Stopień tych przekształceń jest różny i najczęściej jest on większy na drogach o niższej kategorii. Pomimo znacznie większej przepustowości dróg krajowych i wojewódzkich większe zmiany zaobserwujemy na drogach powiatowych i gminnych. Wynika to najczęściej z niższych nakładów finansowych na właściwe przygotowanie podłoża przed budową / modernizacją takiej drogi. Współczynnik zniszczeń dla dróg krajowych wyniósł 0,07 dziur w nawierzchni / km, dla dróg wojewódzkich – 0,2, dla dróg powiatowych – 0,73, a dla dróg gminnych – 0,8. By zniszczenia nawierzchni drogowych były niższe stosuje się jedną z kilku metod ograniczających działanie procesów mrozowych. Zalicza się do nich metodę przechwycenia wody, metodę zastępowania materiału, metodę chemiczną, czy metodę czasowego dociążenia / odciążenia.
Pojęcie, przedmiot i zadania geografii medycznej ze szczególnym uwzględnieniem Polski i Ukrainy
Authors: Góra Dariusz
Published: January 2021

W literaturze naukowej brak jest jednoznacznej odpowiedzi na pytanie, kogo należy uważać za twórcę pojęcia geografii medycznej. W literaturze międzynarodowej termin geografia zdrowia pojawił się dopiero w latach 80., zastępując geografię medyczną. Obecnie geografia medyczna (zdrowia) koncentruje się na badaniu: przestrzennego zróżnicowania incydentów chorobowych i procesu dyfuzji chorób, geograficznych nierówności w poziomie zdrowia ludności i uwarunkowań zachorowalności wśród społeczeństwa krajów rozwijających się. Geografia medyczna w Polsce rozwijała się nierównomiernie. W okresie powojennym zaobserwowano natężenie badań w tej dziedzinie, zwłaszcza na przełomie lat 50. i 60. oraz 80. i 90. XX wieku. W latach 80. i 90. XX w. badacze skupili się na analizie czynników środowiska życia człowieka i jego cech indywidualnych oraz ich roli w powstawaniu społecznych i przestrzennych nierówności w poziomie zdrowia. Obecnie tematyka geografii medycznej (zdrowia) poruszana jest zazwyczaj w pracach doktorskich. Celem artykułu jest próba przedstawienia rozwoju geografii zdrowia, zarówno samego pojęcia jak i kierunku jej badań, począwszy od momentu jej istnienia.

Published: January 2021

Characterizing potential interactions between red ginseng, an herb with desirable health effects, and metformin, a commonly used drug for the treatment of type 2 diabetes mellitus, is of high clinical importance. In this study, we evaluate the effects of Korean red ginseng on the pharmacokinetic and pharmacodynamic properties of metformin in healthy subjects. The study was conducted in an open-label, two-period and single-sequence design. A total of 11 subjects received multiple doses of metformin in the first study period followed by multiple doses of metformin and red ginseng in the second study period. The Geometric Mean Ratio (GMR) (90% Confidence Interval (CI)) between the groups for area under the plasma drug concentration-time curve within a dosing interval (tau) at steady state (AUCtau,ss) of metformin was out of the range of bioequivalence, indicating that the systemic exposure of metformin when combined with red ginseng was reduced compared with administration of metformin alone. However, the pharmacodynamic analysis showed that the GMR (90% CI) between the groups for area under the blood glucose values–time curve from time zero to the time of the last measurable value (AUClast) and maximum blood glucose value (Gmax) were within the range of bioequivalence. We concluded that the observed reduction in the systemic exposure of metformin when administered with red ginseng is clinically insignificant. This study demonstrated that Korean red ginseng did not have clinically significant pharmacokinetic or pharmacodynamic herb–drug interactions with metformin in healthy subjects.

Published: January 2021

The state of mining enterprises of the Russian Federation, despite the development of high-performance equipment and high-efficiency technologies, the use of modern technical means of monitoring the production environment and other measures, is characterized by the preservation of a high level of severe and fatal injuries. An analysis of the accident investigation shows that prior to 90 % injuries and accidents are caused by staff misconduct, including 60 % due to misconceptions about the actual level of danger. This is because the lack of reliable information at all levels of the production system hierarchy does not allow reliable forecasting and timely prevention of dangerous production situations. It is known that the conduct of forensic technical examinations on labour protection in criminal cases related to accidents at work greatly facilitates the work of the investigator. The purpose of this work was to identify safety problems at crushing and sorting factories of quarries based on the results of forensic technical examinations. The work includes an analysis of the results of technical examinations on labor protection of two fatal accidents that occurred in 2016-2017 at transport systems of crushing mills of two quarries of Perm region and conclusions on them are drawn. The main safety problems at the crushing and sorting mills of quarries were identified and recommendations were proposed.
Alteration of initial stress state in the north area of the Sokolov deposit in the course of mining
Authors: Mengel D. A.
Published: January 2021

The stress-strain behavior of rocks is one of the major factors which govern the value and nature of strata pressure, while the latter in many ways determines the safety and efficiency of underground mineral mining. The subject of the research is the stress-strain behavior of rock mass in the north of the Sokolov deposit developed by the underground method. The aim of the research is to study the change in the stress-strain behavior in the north area of the Sokolov deposit in the course of mining. The methods of the research involve the analysis of the stress-strain behavior measured instrumentally using the borehole slotter technique and the comparison of the data with the instrumental measurements of acoustic emission by GS-01 device. The analysis yields that mined-out space has influence on the stress-strain behavior of rocks, while the effective loads across the orebody strike beyond the influence zone of the mined-out area remain yet high and approach the initial values.
Forecast of the stability of the array of gold ore deposits based on the analysis of core material from exploration core drilling wells
Authors: Sosnovskaya E. L. , Avdeev A. N.
Published: January 2021

During underground mining of gold deposits it is necessary to promptly assess the degree of stability and potential impact hazard of rocks. A common and reliable source of information on the structure of the deposit is photodocumented core material from exploration core drilling wells. In the course of research of geotechnical processes at gold ore deposits, the authors developed a method of analysis of the degree of core material destruction in order to identify high-tension areas of rock masses. The method is based on a synergetic scientific and methodological approach. The fractal structure of tectonic fractal fracturing obtained as a result of core material analysis is considered as a consequence of a self-organizing process, the nature of which is associated with the dynamics of tectonic movements of the deposit region. The areas of anomalously fractured core detected as a result of the analysis are used as a marker of zones of increased tension and instability of the rock mass. The proposed methodology has been tested in a number of fields in Siberia and the Far East. As an example of the use of the technique, the analysis of the field of destructive elements of the Karalveem field is considered illustratively. The method allows to make an assessment of the geomechanical situation in conditions of limited information about the tectonic structure of the gold ore deposit.
Geomechanical regularities of horizontal and vertical deformations of the rock mass in the area of the Kachkanar iron ore Deposit
Authors: Tagil’tsev S. N. , Panzhin A. A.
Published: January 2021

Since the beginning of the 2000s, observations of horizontal and vertical deformations of the earth’s surface using GPS technologies have been carried out in the area of the Kachkanar field. It was found that all observation points experience significant deformations. It is shown that the direction of movement is dominated by sub-latitude movements, and the vector of movement is directed mainly to the East. Vertical displacements of support points have a multidirectional character. the array sections that are experiencing a rise, as well as zones that are experiencing a fall, are identified. At the same time, the vertical displacement pattern is cellular in nature. Based on the assumption that the areas of horizontal and vertical movements are formed by the processes of deformation of the rock mass in the field of tectonic stresses, a geomechanical analysis of movements based on active tectonic disturbances is performed. The analysis is based on the patterns characteristic of the tectonic stress field in the Ural region. In the Central part of the field, 4 main zones of vertical deformations were identified. Analysis of the faults separating the compression and stretching zones shows that the vector of the main stress generating tectonic activity of the mountain range is oriented along the azimuth of 285°. The study shows that the upper part of the earth’s crust reacts to a powerful manmade impact associated with the extraction of minerals. The natural field of tectonic stresses generates activation of existing tectonic disturbances and the formation of new ones. The results of modern activation of the geological environment must be taken into account in the operation and construction of man-made facilities.

Published: January 2021

Geophysical methods of research of rock mass are one of the most effective ways of solving various problems in mining and are widely used in mining, gas and oil industry, as well as in science. They allow remote search and assessment works, detection of structural inhomogeneities, voids, contact zones of various media in the rock mass with sufficient high accuracy. The article presents research and comparative analysis of geophysical methods of geophysical sensing and spectral seismo-profiling in underground mine conditions with determination of permissible tasks for which these methods are capable. In complex geophysical studies, methods of spectral seismo-profiling and geo-radar sensing in underground mine conditions have been applied. Measurements were made to search for different objects and at different angles to the object being searched. The use of geophysical methods made it possible to detect the metal shelf under the bulked rock mass with the separation of the boundaries of two tiers of the shelf during vertical measurements. In the process of searching for the underlying excavation in the mass during vertical geophysical measurements, which were carried out 20 meters from the shaft, a change in spectrum density at a depth of about 55 m was detected, which coincides with the actual location of the required mine working. The results of the search for caverns in the rock mass, when taking measurements at an angle to the object sought, showed the absence of sufficiently explicit boundaries of the caverns.
Prediction of ground surface collapse by instrumental observation data on rock mass movements during underground mining
Authors: Kharisova O. D. , Kharisov T. F.
Published: January 2021

Using the data of long-term surveying at the Saranovsky chrome iron ore deposit, movements of rock mass were analyzed with a view to identifying potential early signs of ground surface collapse. The research findings are unique as one of the instrumental observation series was accomplished on the eve of the ground surface sinking above non-backfilled voids of earlier stoping. It was found that the test area experienced vertical alternating movements, and sinking was preceded by upheaval of ground surface. However, the further analysis revealed no clear cause-and-effect between the event and insufficiency of its study. The subsequent research identified a local cluster of rock mass subsidences at gradually increasing velocities, which showed up a few years before the sink appeared on ground surface above its initiation source. The absence of this cluster zone in the period before the collapse is explained by the damage of check points in this site. Finally, the conclusion is drawn that in certain geological conditions, deformation processes are localized and manifest no visible signs of impact on the enclosing rock mass and ground surface. Manifestations of these processes from the instrumental observations concentrate directly in the local area of their development, which should be taken into account in the analysis and prediction of movements. It is emphasized that the existing and new criteria of hazardous deformation processes should be corrected and updated for geomechanical monitoring of mineral mining objects.

This paper systematically deals with the matter of nomotechnical rules of drafting legal regulations with special reference to essential preconditions of drafting legal regulations. The national sources of law are studied relating to the procedure of drafting legal regulations, which arise from the Rules of Procedure of the Croatian Parliament and what possibilities the prescribed and unique methodological-nomotechnical rules have. The emphasis is on determining the essential preconditions for the enaction and drafting of legal regulations, and on the advantages that contribute to a better drafting of legal regulations in the national system. This is a very interesting topic since the so-called nomotechnical rules did not appear in scientific terms until the 19th century and are still evolving. The nomotechnical rules institute plays a very important role as a foundation of legal certainty.

Published: January 2021

The results of experimental investigations of the influence of distributed suction through a finely perforated surface on the spatial development of perturbations of the straight wing boundary layer at the nonlinear stage of its evolution are presented in this article. It was found that distributed suction reduces the intensity of integral pulsations for natural disturbances by 90 times. A spectral analysis of disturbances showed a decrease in the intensity of high-frequency fluctuations in a narrow frequency band by two orders of magnitude for natural and forced disturbances generated by an external acoustic field. It was found that the distributed suction affects the average flow, namely, when the suction is on, the turbulent state of the boundary layer is eliminated, its separation near the trailing edge of the wing and the laminar flow is defined in the boundary layer.
The Interrelation between the Optical Coefficients of Ultrathin Metal Films and Their Geometric Parameters of Surface Morphology
Authors: Mazinov Alim S.
Published: January 2021

The theoretical and experimental data on the study of the optical coefficients of electromagnetic waves in the super high frequency range 2–4,5 GHz and their relationship with the thickness of the conductive films by the example of aluminum are presented. It is showed that transformation of the relief of a thin-film structure with an increase in the bulk mass of the deposited material causes an increase in surface roughness with a maximum of 7 nanometers. It is worth noting that exactly for these thicknesses of the studied films the maximum absorption of the incident electromagnetic wave is experimentally achieved. Meanwhile, a theoretical calculation of the reflection, transmission and absorption coefficients showed the maximum absorption of the incident wave at a thickness of 5 nm. The difference between the experimental and theoretical values of the absorptivity is explained by the non-ideal geometry of ultrathin conductive surfaces. At the thicknesses from 1 nm to 10 nm the film itself is formed in the form of separate nanoislands.

Kuzbass: structural factors of regional dynamics
Authors: Fridman Yuri A. , Rechko Galina N. , Loginova Ekaterina Yu. , Khokhrina Olesya I.
Published: January 2021

The article on the basis of the method of structural shifts analyzed the dynamics and structural transformations of employment and production of gross value added (GVA) in the Kemerovo region - Kuzbass. The authors attempted a quantitative analysis of the contribution of structural factors to economic dynamics, as well as an assessment of trends in diversification of region production. The basis for the calculations was compiled by state statistics for 2007-2018. It was shown that during this period regional employment dynamics were determined mainly by regional factors, whose contribution to the growth of this indicator turned out to be negative. In turn, the dynamics of GVA production was due to a complex of national trends and regional factors, whose influence was multi-directional (the positive effect of macroeconomic conditions and the negative contribution of the regional component). The contribution of structural shifts to the growth of the GVA was negative and insignificant, and the reduction in the number of employees in Kuzbass took place with an almost unchanged structure. To date, in the Kemerovo region, using a diversification mechanism, it has not been possible to create an economy structure resistant to internal and external shocks: coal mining remains the fundamental basis of the region's economy. All this gives reason to state that the structure of the economy that was formed in Soviet times, and the features "inherited" by it since then, continue to determine the dynamics of the development of Kuzbass and serve as a strategic challenge for the region.
On some dangerous practices for supporting public sector worker
Authors: Erzhenin Roman V.
Published: January 2021

The article studies the correctness of setting goals and establishing norms in the regional segment of social support for the population and some of the consequences of this issue. As an example, the author examines the decrees of the Governor of the Irkutsk Region on social support for public sector employees issued in the period 2017-2019. An analysis of the provisions set forth in the decrees and the approved procedures for submission of lump sum payments highlights the non-traditional methods of organizing transfers of budget funds to employees of the state and municipal organization in the region. In addition to giving budget workers the right to receive a lump sum payment on professional holidays, the decrees of the Governor of the Irkutsk Region in violation of federal law exempted these payments in the amount of RUB 1.5 billion from taxation. According to the author, the motive to avoid generally accepted mechanisms for fulfilling budget expenditure commitments could be a desire to receive unreasonable tax benefits for the regional budget by reducing payments to budgets of other levels and extra-budgetary funds. The obtained results of the research can be used to develop the guidelines for limiting the regional rule-making in the field of social support based on subjective understanding of unreasonable norms-goals.

Este artigo buscou analisar, por meio de revisão de literatura, a inter-relação entre parto cesariano e depressão pós-parto, avaliando causas, fatores de risco e reflexos. A depressão pós-parto é um distúrbio mental que afeta entre 10 e 20% da mulher e é observada, sobretudo, em gestante que experimentaram sintomas relacionados ao estresse, à ansiedade e à depressão, podendo também estar associado a condições sociais. A cesárea está associada a alterações biológicas no corpo da mãe, como variação do nível sérico de hormônios, de prolactina e de interleucina-6, a hemorragia, além de sensações de medo e dor. Mulheres primíparas, sobretudo com mais de 30 anos de idade, correm maior risco de apresentarem depressão pós-parto, assim como aquelas que tiveram uma gravidez indesejada ou não intencional. Além das repercussões do quadro depressivo para a mulher, o que inclui ideações suicidas e alterações na função sexual, há maior risco de infanticídio, atraso no desenvolvimento de habilidades de comunicação do bebê e aumento nos gastos com saúde. Assim, verificou-se a necessidade de a depressão pós-parto ser considerada por clínicos, visto que pode surgir antes ou depois do parto, ressaltando a importância da avaliação precoce, a qual pode incluir intervenções psicológicas, farmacológicas e hormonais.

Published: January 2021

Subaponeurotic fluid collection (SFC) is a rare cause of scalp swelling in infants that is not well described in textbooks. It can be diagnosed clinically and managed conservatively. We report two infants, who had scalp swelling, with findings suggestive of SFC that resolved spontaneously. We have reviewed literature on the possible mechanisms of fluid collection. We wish to highlight the self-limiting nature of this condition so that unnecessary investigations, referrals, and interventions are avoided.

The World Health Organization (WHO) describes infertility as a disability for couples in childbirth to attain pregnancy within 12 months of daily sexual intercourse. The reproductive years of women starts when she starts her menstrual cycle during puberty and capacity to have a child typically ends about age (45) years. However, it may be possible for a woman to become pregnant before her cycles end with menopause. Infertility affects 13–20 per cent of couples worldwide, regardless of race or ethnicity. The present study aim was  To study the levels of prolactin and beta hCG in female infertility. And To correlate the levels of prolactin and beta hCG in infertile womens and healthy controls. The present study was conducted in the departments of biochemistry and dept. of obstetrics and gynaecology. The study was conducted on two groups of 40 infertile Females and 40 healthy controls. Serum sample used for estimation of prolactin and hCG, assessed by dry chemistry analyzer. Serum prolactin levels in infertile females is 33.96±11.46 and hCG levels was 86.38±12.45, which was higher in infertile female as compared to healthy control with a p-value of<0.05. The present study  concludes that Hyperprolactinemia is a major contributing hormonal factor in infertility among infertile women and, as such, prolactin and hCG should be measured in infertile women.
CULTURAL TRAUMA: MEMORY, OBLIVION, REPRESENTATION

Published: January 2021

В последние годы одной из самых актуальных проблем общественной науки становится проблема культурной травмы. По этой теме выходят сотни статей, монографий. Чрезвычайно популярным является направление Cultural Studies. Как формируется культурная травма? Как превращается из коллективной, коммуникативной в культурную? Что представляют собой память, интерпретация, забвение, репрезентация? Какую роль в этом процессе играют репрезентанты, носители, создатели новых культурных смыслов? Как в культуре возникает новый смысл, который коренным образом трансформирует сознание, жизненный мир, социальные связи? Смысл открывается, обнаруживается как нечто данное, как «объективная реальность» или же выдумывается, строится по образцу мифа, сказки? Как выстраивается борьба интерпретаций смыслов, их сохранение, проработка, разрушение, забвение? Какое значение имеют в этом процессе репрезентации медиа, праздники, традиции, фильмы, сериалы, музеи, общественные дискуссии и пр.? В статье дан анализ этих проблем с позиций умеренного конструктивизма.

In recent years, one of the most pressing problems of social science is the problem of cultural trauma. Hundreds of articles and monographs are published on this topic. The direction of Cultural Studies is becoming extremely popular. How is cultural trauma formed? How does it turn from a collective, communicative into a cultural one? What are memory, interpretation, oblivion, representation? What role do representatives, carriers, creators of new cultural meanings play in this process? How does a new meaning arise in culture that radically transforms consciousness, the life world, and social ties? The meaning is revealed as something given, as «objective reality» or is it invented, built on the model of a myth, a fairy tale? How is the struggle between interpretations of meanings built, their preservation, elaboration, destruction, oblivion? What is the significance of media representations, holidays, traditions, films, TV shows, museums, public discussions, etc. in this process? The article analyzes these problems from the standpoint of moderate constructivism.
I. BERLIN'S PHILOSOPHY: HISTORY AND ITS METHOD
Authors: Потамская Вера Павловна
Published: January 2021

Рассматривается трактовка истории И. Берлином. Следуя гуманистическому подходу Вико, Берлин отвергает идею применения естественно-научной методологии к человеческим делам. Определяется, что значительную роль в восприятии истории играют чувство реальности и воображение. Выявляется наиболее значимая для Берлина мысль, нашедшая отражение в представлениях Вико и Гердера, - именно различия, а не сходства определяют завершенность познавательного акта, исторического описания, индивидуальности, будь то предмет, человек или культура.

The article is devoted to Berlin’s interpretation of history. Following Vico's humanistic approach, Berlin rejects the idea of applying natural science methodology to human affairs. He claims that the comprehension of reality meaningful content and imagination play a significant role in the interpretation of history. The most significant Berlin’s thought, derived from the ideas of Vico and Herder, is revealed: it is differences, not similarities, that determine the completeness of the cognitive act, historical description, individuality, or culture.
Effect of different type of soil as growing media on physiological quality of harvested okra (Abelmoschus esculentus)

Soil properties are very important to be well understood before planting any crop.
Different types of soil will possess different properties. The properties of soil will
influence the yield and quality of crops. For instance, poor soil properties will produce
low quality of okra, thus reducing consumer demand. It is necessary to find conditions that
are suitable for soil in order to get the best okra quality to fulfil the demand of consumers.
The purpose of this research is to determine the physiological quality of harvested okra on
different types of soil which are peat soil (T1), mineral soil (T2) and alluvium soil (T3).
Each treatment was replicated five times and was applied with the same amount of
fertilizer (NPK 12: 12: 17: 2); 10 g. Parameters in term of quality of physical appearances
were taken once after the fruits were harvested. The parameters taken include the length of
fruit (cm), the diameter of fruit (mm), the colour of fruits and fruit tenderness. Parameters
for growth performance were also taken for each treatment. The result obtained shows a
high significant difference in term of physical features of okra such as length of fruit (cm),
the diameter of fruit (mm) and fruit tenderness for each treatment. Harvested alluvium soil
-based okra was found to be the most promising for fruit yield, physical quality and
quantitative characteristics. This is because the result of parameters of alluvium soil (T3)
is higher than peat soil and mineral soil in term of length of fruits; 17.18 cm, diameter of
fruit; 19.42, yield produced; 9.8 and tenderness; 9.2. The T3 soil also has rich in
micronutrients especially potassium. In conclusion, properties of soil whether chemically
or physically will influence the yield and quality of crops either directly or indirectly.
Effect of essential oils of oregano (Origanum vulgare), thyme (Thymus vulgaris), orange (Citrus sinensis var. Valencia) in the vapor phase on the antimicrobial and sensory properties of a meat emulsion inoculated with Salmonella enterica

The demand for healthier meat products is increasing remarkably and natural
antimicrobial agents such as essential oils (EOs) are required, which can be applied in the
vapor phase. For this experiment, the effectiveness of essential oils of oregano, thyme, and
orange in the vapor phase on the microbiological and sensory characteristics of sausages
inoculated with Salmonella enterica and stored at 4°C during 72 hrs and 144 hrs, were
studied. Oregano EO with 2000 ppm was the most effective treatment against Salmonella
enterica with a logarithmic reduction of 1.97 Log10 CFU/g compared to thyme 1.36 Log10
CFU/g and orange 1 Log10 CFU/g) after 144 hrs. In relation to the general acceptance
level, the meat product exposed to the orange EO in vapor phase presented the highest
approval by the judges nevertheless, however, were the ones that showed the least
reduction in the microbial population. Finally, the results showed that the addition of
essential oil in the vapor phase to meat products exerted a bactericidal effect with higher
EOs concentrations and some also caused alterations in the sensorial properties of the
product.

Mangosteen fruit (Garcinia mangostana L.) is consumed mainly for two purposes, i.e., its
aril for fresh or minimally processed products and its rind for herb and other health-related
products. In fact, due to the high portion of rind compared to its whole fruit, its rind has a
more important economic value, especially for its α-mangostin content. This study
reported the effects of flower baggings on the α-mangostin content during mangosteen
fruit growth. This field research was conducted in a farmer’s field at Gisting village,
Tanggamus District, Lampung Province, Indonesia. The study was arranged in a 2 × 3
factorial design. The first factor was bagging date [2 and 4 weeks after anthesis (WAA)],
and the second one was bagging material (unbagged or control, banana ‘Cavendish’-
paper bag, and balloon). Fruit samplings were conducted in every two weeks during the
periods of 8-16 WAA. The α-mangostin content was analyzed with HPLC [DionexUltiMate® 3000, autosampler, column compartment, Ultimate 3000 pump, UV detector,
column Enduro C-18 (250 mm × 4.6 mm, 5 µm) with C18 guard]. The results showed that
the α-mangostin content increased in a sigmoid pattern during fruit growth, and the
increase was mostly not affected by bagging, bagging materials, and application periods.
The α-mangostin content increased tremendously during 10-14 WAA, regardless of
bagging, bagging materials and application periods. Bagging had resulted in the decrease
of α-mangostin content during the latest period of fruit growth, regardless of bagging
materials and application periods
