Published: April 2019

The objectives of this research were two: first to investigate experimentally the behavior of pineappl (Ananas comosus, L.) thin layer drying in a greenhouse-type solar dryer and second to describe the best fitting kinetic and mathematical model taken from literature. A large scale greenhouse dryer designed and installed at Silpakorn University, Nakhon Pathom, Thailand was used to dry slices 1 cm width at temperature range between 25-60 °C with relative humidity between 50-90%. Nine statistical models, either empirical or semi-empirical, were tested in order to validate the experimental data. A non-linear regression analysis conducted by a statistical computer program was applied to evaluate the constants of all the models. The parameter values, root mean square error (RMSE), mean absolute error (MAE) and modelling efficiency (EFF) of the nine models were calculated. Comparison outcomes of two experiments are displayed between the predicted moisture content and the observed pineapple moisture content. Hasibuan and Daud drying model proved to describe the best pineapple solar drying curves. The two experiments were carried out on sunny days, the second experiment on the third day showed cloudiness decreasing the solar radiation. Mathematical models of pineapple drying in a greenhouse dryer have not been found so far in the literature. Drying curves obtained from experiments showed that the constant drying and the falling drying rate periods exist. Nine thin-layer drying models were fitted to two experimental data in order to describe the drying characteristics of pineapple founding that the Hasibuan and Daud model was the best fitting.

Authors: Olivares Gallardo Alan Paulo , Guerra Rojas Rodrigo Alejandro , Alfaro Guerra Marco Antonio
Published: April 2019

En el presente trabajo se diseñó y construyó un sistema hidráulico para la determinación experimental delfactor de fricción en una tubería de PVC bajo flujo turbulento. Este sistema permite conducir el agua por una tubería donde se midieron el caudal y la diferencia de presión para calcular la pérdida de carga entre dos puntos de control, considerando las propiedades asociadas a la tubería como es la rugosidad relativa, su diámetro y longitud. Utilizando la ecuación de Darcy-Weisbach se determinó el factor de fricción experimental. El objetivo del presente trabajo fue evaluar en forma experimental el factor de fricción y compararlo con el obtenido utilizando la fórmula n-ésima como aproximación de la solución exacta de la ecuación de Colebrook-White propuesta por Mikata y Walczak en 2015. La fórmula n-ésima predice el factor de fricción con un error relativo que tiende a disminuir dependiendo de la profundidad de la recursión. En nuestro análisis, para un valor de n igual a 15 el error en la determinación del factor de fricción reportó valores inferiores a 1E-16. Se desarrolló una macro de Excel en lenguaje VBA para evaluar la recursión dada la dificultad numérica de resolver el valor analítico exacto de la ecuación de Colebrook-White. La originalidad del presente trabajo corresponde a la evaluación de la fórmula n-ésima del factor de fricción y su comparación con los resultados experimentales obtenidos en el laboratorio, lo que permite probar la validez de la predicción de la fórmula con un caso real. Esto permitió encontrar el error relativo porcentual respecto al valor experimental.
EFFECTIVENESS VS. EFFICIENCY: AN ANALYSIS OF VALENCY AND COLLOCABILITY IN A TECHNICAL CONTEXT
Authors: Filyasova Yulia A
Published: April 2019

Abatract. The article presents the results of a lexico-syntactic analysis of valency and collocability of English words, related to one semantic group: effectiveness and efficiency . The aim of the research was to study the ability of these words to syntactically and lexically contact with other words, taking into consideration certain difference between their lexical meanings. The objectives included determining semantic variations and analysis of word classes in the left and right contexts. The material, 177,144 words, comprised 700 article titles and abstracts from seven international journals with geological and petroleumrelated specializations. Methods of study involved continuous sampling, classification, and analysis of lexical meanings of relevant words. It was found that the frequency of effectiveness was 40% higher than that of efficiency. Both of them had similarities in syntactic valency: they occurred in identical syntactic structures, however, with different rates of occurrence. The difference is the most obvious in such syntactic structures as N(E)+of+N - characteristic of effectiveness, and V+A+N(E) - specific to efficiency. A typical example of effectiveness was the effectiveness of the proposed method , while that of efficiency - improve production efficiency . Effectiveness collocated more often with method-related notions, whereas efficiency - with processes. The gained data correlate with the definitions: effectiveness has a wider semantic field (which explains a higher rate of its occurrence) and is oriented towards result, while efficiency implies process and has an additional technical meaning. The data can be used in the practice of teaching English as a second language for students with technical specializations and technical translation.
ACTIVE PROCESSES IN MODERN RUSSIAN IN THE LIGHT OF DETERMINANTAL ANALYSIS
Authors: Valentinova Olga I , Rybakov Mikhail A
Published: April 2019

The authors of the article discuss the possible ways to analyze the facts of mass modern Russian speech, which are traditionally considered from a normative-didactic point of view, from the standpoint of systemic linguistics, that is, applying analysis of the relationship between the determinants of a language of a certain morphological type and particular phenomena at all levels of linguistic structure. Such facts include, for example, violation of case coordination, use of nominative case instead of indirect, occurrence of the plural in abstract nouns outside the formation of concrete figurative meanings, incorrect usage of verb voice forms, luck of correlation between subject and verbal participle, lack of correlation of wordorder structure of a sentence to the communicative (thematic-rhematic) structure of an utterance, the misuse of synonyms, etc. The method of determinant analysis of languages developed within the framework of a systemic typology allow researchers to identify the tendency to break down inflectional connections between words at a formal and substantive level, which is surely fixed in modern Russian, and increase the analytical methods of constructing a phrase. The deformation of the inflection of the Russian language, caused by the growth of the national, social and cultural heterogeneity of the linguistic group, while retaining such parameters of the external determinant that determine the inflectional grammatical type, like the scale of the linguistic collective and the mode of communication, not only makes it difficult to express complex meanings, but also makes them ultimately account unclaimed in society, reducing the continuity in the transfer of socially significant experience. The authors focus on such problems as comparing the typological standard of inflectional languages and characteristics of the grammatical system of the Russian language, the correspondence of the accepted literary norm to the typological ideal, the correspondence of mass speech practice with the literary norm, the factors changing the frequency of grammatical forms, the interaction of external and internal determinants of the modern Russian language. The theoretical basis of the article was developed in the second half of the 20th century, but still not widely known in linguistics the systemic linguistic concept of Professor Gennady Prokop'evich Mel’nikov, which revealed large prospective for the synthesis of special linguistic disciplines, as well as linguistics, semiotics and computer science.
Group Medical Visit Training in Family Medicine Residency:
Authors: Strickland Carmen , Sandberg Joanne C. , Davis Stephen W. , Weaver Sally P.
Published: April 2019

Background and Objectives: Group medical visits (GMV) have been shown to improve clinical outcomes and patient satisfaction and are included as a new tool in the patient-centered medical home (PCMH). The capacity for and interest in developing GMV skills in family medicine residency have not been assessed. This study aims to describe the extent of existing training in GMV as well as attitudes toward and barriers to this training.
Methods: The Council of Academic Family Medicine Educational Research Alliance (CERA) sent a survey in the fall of 2015 to all US family medicine residency program directors (PDs) containing questions about the status of GMV training for their residents.
Results: The survey response rate was 53%. Fifty-nine percent of program director respondents report access to GMV and 61% note some form of training in this model of care. Seventy-nine percent of respondents indicate that GMV training is important for residents. Multiple barriers exist to optimizing GMV as part of current family medicine training.
Conclusions: A majority of family medicine PD respondents report both access to and curriculum for GMV. While program directors endorse this practice model as an important element in resident training, they acknowledge challenges that may limit its availability. Opportunities to better understand and overcome barriers may increase programs’ capacity to deliver GMV skills.
Exploring Change After Implementation of Family Medicine Residency Curriculum Reform

Published: April 2019

Background and Objectives: In 2010, the College of Family Physicians of Canada (CFPC) launched its competency-based medical education (CBME) approach to residency curriculum and assessment. Named Triple C, this innovation was developed to ensure graduates of family medicine training programs are competent to begin unsupervised practice. Further, Triple C was intended to promote interest in practicing comprehensive family medicine. A program evaluation plan was launched by the CFPC alongside the implementation of Triple C to explore if intended outcomes were achieved.
Methods: We conducted retrospective secondary data analysis of survey findings from graduating family medicine residents from two sources: National Physician Survey (NPS 2007 and 2010); and the Family Medicine Longitudinal Survey (FMLS 2015). Demographics and practice intentions reported by residents in the NPS 2007, NPS 2010, and FMLS 2015 were included in the analyses and a comparison between years was undertaken using a series of Pearson χ2 test.
Results: Findings indicate that in comparison to pre-Triple C (NPS 2007 and NPS 2010), significantly more residents reported the intention to include palliative care, intrapartum care, in-patient hospital care, care in the home, and practicing in rural settings after the implementation of Triple C (FMLS 2015; P<0.01).
Conclusions: Family medicine graduates report an increase in intention to include a broader range of clinical domains after implementation of Triple C. While a causal relationship cannot be determined, using a historical control in the form of survey data that predates Triple C implementation could support future approaches to evaluation of education reform.

The paper presents results of the influence of mechanical activation of
shungite, a carbon-mineral rock material rich in silica and carbon, on its
sintering behaviour, and obtaining of pure SiC ceramics. The mechanical
activation of the starting powder was performed in a high-energy ball mill
in time intervals from 30 to 480min. The phase composition of the starting
powders and sintered samples was analysed by the X-ray diffraction method.
The first traces of SiC were detected after sintering at 1350?C for 2h in
an Ar atmosphere, along with traces of unreacted SiO2. The scanning electron
microscopy was performed in order to determine changes in the
microstructure. Sintering was performed at various temperatures for 2 h, in
an Ar atmosphere and a vacuum. Dielectric properties of the sintered samples
were measured in the frequency range from 1 to 500MHz. The obtained results
indicate that the sintered powder is a good candidate for applications as an
absorber of electromagnetic waves in microwave engineering. [Project of the

Magneto-dielectric properties of ferrites and ferrite/ferroelectric multiferroic composites
Authors: Dzunuzovic Adis , Vijatovic-Petrovic Mirjana , Ilic Nikola , Bobic Jelena , Stojanovic Biljana
Published: April 2019

Ni-Zn ferrites, with the general formula Ni1-xZnxFe2O4 (x = 0.0, 0.3, 0.5,
0.7, 1.0), CoFe2O4, BaTiO3 and PbZr0.52Ti0.48O3 powders were synthesized by
auto-combustion method. The composites were prepared by mixing the
appropriate amounts of individual phases, pressing and conventional
sintering. X-ray analysis, for individual phase and composites, indicated
the formation of crystallized structure of NiZnFe2O4, BaTiO3 and
PbZr0.52Ti0.48O3 without the presence of secondary phases or any impurities.
SEM analyses indicated a formation of uniform grain distribution for
ferromagnetic and ferroelectric phases and formation of two types of grains,
polygonal and rounded, respectively. Magneto-dielectric effect was exhibited
in all samples because of the applied stress occurring due to the
piezomagnetic effect and the magnetic field induced the variation of the
dielectric constant. For all samples the dielectric constant was higher in
applied magnetic field. At the low frequency, the dispersion of dielectric
losses appeared, while at the higher frequency the value of tan ? become
constant (Maxwell-Wagner relaxation). Investigation of J-E relation between
leakage and electric field revealed that both nickel zinc ferrite and
composites have three different regions of conduction: region with ohmic
conduction mechanism, region with the trap-controlled space charge limited
current mechanism and region with space charge limited current mechanism.

Published: April 2019

Chronic venous insufficiency (CVI) is a common, but underdiagnozed clinical disorder associated with a variety of signs and symptoms. The presence of leg edema in association  with varicose veins, and venous leg ulcer in later disease stages defines the disease. The pathogenesis of chronic venous disease  is based on venous reflux, obstruction, or a combination thereof.  Prior postthrombotic syndrome   is one of risk factor for CVI which may explain observed  prevalence of thrombophilia in CVI. Color flow duplex ultrasound is the gold standard for nearly all diagnostic issues related to chronic venous disease. Compression stockings are the mainstay for conservative management. Earlier use of venous ablation therapy should be considered in symptomatic patients with superficial tortuous vein
MODELING THE EFFECTS OF LEAD POLLUTION ON LACTATE DEHYDROGENASE ACTIVITY
Authors: Konovalova Olena
Published: April 2019

The changes of activity of LDH and its isoenzymatic fractions under load with lead acetate are described. The introduction of a subacute dose of Pb2 + led to a decrease in the LDH activity of the rat liver and an increase in the heart. Preliminary introduction of small doses of Pb2 + partially prevents increased LDH activity in the heart and completely inhibits its increase in the liver. The proportion of urea-stable fraction in the heart and blood serum is significantly increased, indicating an increase in the aerobic direction of energy metabolism. The obtained results are the experimental substantiation of further investigations of influence mechanism of heavy metals on the organism, as well as the motivation to prevent environmental pollution by man-made xenobiotics.

Authors: Dosviadchynska Mariana , Antonyak Halyna
Published: April 2019

Contamination of agricultural products with mycotoxins is a widespread phenomenon that is manifested in many countries. Among mycotoxins, which significantly affect human and animal health, aflatoxins produced by Aspergillus micromycetic fungi (mainly A. flavus) are of serious concern because of their high toxicity and carcinogenicity. The aim of our study was to investigate the effect of aflatoxin B1 (AFB1) on intracellular metabolism in laboratory animals. The dynamics of the lipid peroxidation (LPO) and activities of antioxidant system enzymes (superoxide dismutase, glutathione peroxidase, and glutathione reductase) in lung cells and erythrocytes of white rats were analyzed within 14 days after administration of AFB1 (dose 1/10 LD50). The results of the study have shown the activation of the LPO processes and a decrease in the activity of enzymes of the antioxidant system in the cells of rats of the experimental groups. In general, the obtained results suggest the development of oxidative stress in the lungs cells and erythrocytes of animals under the influence of aflatoxin B1.

Published: April 2019

Studied the issues of the water quality suitable for consumption in some mountainous regions of Lviv region, in particular in Skolivsky, Turkivsky, and Starosambirsky districts. The obtained results based on the main hydrochemical indicators show the water quality meets the requirements for the degree of pollution of the hygienic classification of water objects. The conditions for the habitat of hydrobionts and terrestrial biota are normal. Most water samples have a weakly alkaline reaction, indicating a possible high content of hydrocarbonates. Concerning the hardness, all studied samples are soft and medium hard water types. The value of total alkalinity of water samples ranges from 1.8 to 6.1 mmol/m3, which corresponds to the physiological integrity of the composition of drinking water. Sulphate ions and chloride ions are present in almost all natural waters, their content is mainly due to chemical weathering with sedimentary rocks during oxidation of sulfides, dissolution of sulfur-containing and chlorine-containing minerals.It has been investigated the sequence between hardness of water and non-infectious diseases in the studied regions. Constant consumption of such water may cause a danger to the population suffering from cardiovascular disease, blood congestion, myocardial infarction.

BIOCHEMICAL INDICES OF PROOXIDANT-ANTIOXIDANT PROCESSES IN CALENDULA OFFICINALIS L., GROWN UNDER THE INFLUENCE OF GROWTH BIOSTIMULANTS
Authors: Lupak Oksana
Published: April 2019

The effect of plant growth biostimulants «Vermymag», «Vermyiodis» and «Vermystym» on the content of enzymes of antioxidant protection and metabolites of the prooxidant-antioxidant system of C. officinalis flowers of the cultivated variety «Poliova Krasunia» cultivated in the soil and climatic conditions of the Precarpathian region has been analyzed. It was shown that applying biostimulants during cultivation of C. officinalis flowers contributed to the increase (p<0.05-0.01) of antioxidant enzymes activity compared with control plants. In particular, the superoxide dismutase and catalase activity was higher with applying biostimulants «Vermymag» and «Vermyiodis». The biostimulant «Vermymag» had a positive influence on the peroxidase activity, contributing to the increase of enzyme content up to 21% comparing with the control. The content of ascorbic acid increased under the influence of all biostimulants in plant cells. The use of stimulants positively influenced the redox state of C. officinalis cells, contributing to suppressing lipoperoxidation processes and increasing the resistance of plants to the action of stress factors. It is found out that growth biostimulants promote the balance of prooxidant-antioxidant processes in C. officinalis plants.
Communicating Cultural Heritage Resources to the Public: Experiences from the Makonde of Mtwara Region, Tanzania.
Authors: Gabriel Festo Wachawaseme
Published: April 2019

Communicating cultural heritage to the public has gained popularity in many African countries and the world at large. However,little efforts have been done to promote the practice of public archaeology in Tanzania. The main reason is the dominance of conventional archaeology which is mainly meant for academic consumption. In this kind of practice, the participation of local communities has been passive. This paper explores local communities’ understanding of cultural heritage resources focusing on local communities in the Mtwara Region of Tanzania. The results of this study reveal that little effort has been made by archaeologists and cultural heritage professionals to create awareness among local communities on matters related to archaeology and cultural heritage resources. Apart from discussing the state of local communities’ awareness on archaeology and cultural heritage resources, the paper also discusses the importance of communicating cultural heritage resources to the general public and the need to engage local communities in the conservation and preservation of cultural heritage resources.
Russia-Japan Security Dialogue
Authors: Paramonov O. G.
Published: April 2019

In the face of deteriorating the regional security environment in East Asia, a noticeable growth of Japan’s defense capabilities and Tokyo’s departure from most self-restraints in the field of security policy look quite expected and natural process. At the same time, Japan continues to rely on the alliance with the United States. On the other hand, relations between Washington and Moscow are now at their lowest point since the Cold War. Japan itself has territorial claims to Russia. This means, based on confrontational logic that returns to the international agenda, that Japan’s traditionally reserved attitude towards Russia should be maintained. However, today we are witnessing a different situation. After the start of regular personal meetings between Russian President Vladimir Putin and Japanese Prime Minister Shinzo Abe, the dialogue is intensified on a wide range of issues, including those related to international security, and especially its regional aspect. Although certain background for that was noted before the Sochi meeting between V. Putin and S. Abe, this foreign policy turn, and, in particular, its speed, came as a surprise not only for Tokyo’s Western partners, but also for many Japanese politicians and experts. This article is devoted to the analysis of its possible causes, as well as the search for an answer to the next question.Is the dialogue between Russia and Japan a situational political maneuver or a step towards cooperation on security issues?
Russia-Australia Relations before and after the Ukrainian Crisis
Authors: Krivushin I. V.
Published: April 2019

The crisis of Australian-Russian relations after Russia’s annexation of Crimea in March 2014 and the set of factors that caused it have received little attention from scholars of international affairs. The article contributes to addressing this research lacuna. It examines the 2014–2015 crisis in bilateral relations from the point of view of both Moscow and of Canberra. The author analyses the evolution of these relations before 2014 to understand whether the Ukrainian crisis was the cause of their sharp deterioration in 2014–2015, or it only accelerated the process that began much earlier. He demonstrates that Australia had no close political and economic ties with Russia, and the two countries did not consider each other as priority partners. The article finds that in 2014–2015 the Kremlin did not take into account a number of factors, such as very limited interest of Australia in commercial exchanges with Russia, Canberra’s growing suspicions about Moscow’s foreign policy intentions and view of Russia as a revisionist power (especially after the 2008 Russia-Georgia war), a strong sense of solidarity with the West among Australia’s political elites, and Russia’s increasingly worsening public image in Australia, that negatively affected Canberra’s stance towards the Kremlin even before 2014, and which greatly contributed to the crisis in bilateral relations. As for future development, the author identifies two factors that may have a negative impact on Russian-Australian relations: 1) rising energy demand in China and India, making Russia and Australia potential competitors in Asia’s gas markets; 2) a too close rapprochement of Moscow with Beijing, fraughtwith the risk of embroiling Russia in a web of conflicts in the Western Pacific.
Russia, China and the Pacific Countries of Latin America: Opportunities for Multilateral Cooperation in the Asia-Pacific Region
Authors: Novikov D. P.
Published: April 2019

The article is devoted to the problems of the development of modern relations of Russia, China and the  Pacific states of Latin America. Author focuses on potential of cooperation of these states in multilateral  formats and dialogues and the reform of the economic and institutional order in the Asia-Pacific. The  relevance of such cooperation is increasing due to the crisis of the international order that has emerged  in the Asia-Pacific region. This crisis manifests itself in two aspects. First, we may observe a certain lack  of institutions of regulation of economic relations and ideas for their further development. Such a  complex agenda is shaped by Russia and China in relation to Eurasia (the concept of “Greater Eurasia”),  but the promotion of a similar agenda in the APEC faces many contradictions. Second, the Asia-Pacific region is becoming an area of confrontation between the United States and China, which is also  manifested in the struggle for the future configuration of the regional order in the region. The Pacific  countries of Latin America were not affected by either the Russian or Chinese mega-initiatives of recent  years, which are aimed precisely at creating a new international order. Meanwhile, these countries are  APEC members and participants in many regional initiatives, as well as potentially significant economic  partners for both Russia and China. Moreover, the author believes that a similar level of economic  development and similar needs objectively bring together the views and approaches of the leading  Eurasian powers and the Pacific states of Latin America to the development of multilateral institutions of  the regional order. However, the historically established institutional and political linkage of these  countries to the United States currently determines their support for American initiatives. This provision, however, is not a given, and some irregularity of the American regional policy under the Trump  administration makes the development of dialogue with these countries on the broad problems of  multilateral cooperation in Eurasia and the Asia-Pacific region even more in demand. The author  considers the proposed analysis and some conclusions as an opportunity for academic and expert  discussion on the identified issues.
Greater Eurasia, Indo-Pacific Region and Russia-ASEAN Relations
Authors: Kanaev E. A. , Korolev A. S.
Published: April 2019

The article aims to specify the influence of the projects the Greater Eurasia and the Indo-Pacific Region on the prospective relations between Russia and ASEAN. The key component of its novelty is the authors’ original criteria of comparing the two projects: the degree of consolidating agenda of cooperation between their current and prospective participants, the congruence with the East Asia’s – assuming that it will be the economic driver of the forthcoming Greater Eurasia and Indo-Pacific Region – modality of multilateral dialogue and the preconditions for the survivability of both projects in the long-term perspective. Making this comparison, the authors substantiate the view that the Greater Euraya  sian Partnership is far more competitive that the Indo-Pacific Region. Exploring cooperation between Russia and ASEAN through the prism of their forthcoming strategic partnership, the authors offer an original interpretation of the reasons behind the presently insufficient cooperation and its most likely future directions proceeding from the mutual influence of Russia’s and ASEAN’s prospective planning and the emerging global context. In the near future, combating international terrorism and strengthening connectivity will come to the forefront of Russia’s and ASEAN’s priorities, with the focus shifting from Southeast Asia to the Eurasian area. In the authors’ view, if the present trends continue the aftereffects of the Indo-Pacific Region can stimulate downward trends in the Russia-ASEAN relationship. This will be premised upon the decrease in effectiveness of the Asia-Pacific multilateral dialogue platforms, likely Russian-Chinese joint maneuvers in the South China Sea and the necessity to specify, along with lack of impressive results, the essence of the Comprehensive Strategic Partnership between Russia and Vietnam as the foundation for the Russia-ASEAN strategic partnership. In its turn, the Greater Eurasia offers Russia and the association new promising possibilities, among which of particular importance are the development of connectivity narrative in Eurasia and combating international terrorism by means of adopting the ASEAN-led dialogue platforms ARF, ADMM+8 and EAS to the future system of security, cooperation and co-development from Lisbon to Jakarta. The realization of the forthcoming shift from the Asian century to the Eurasian century and the emergence of the Greater Eurasia as the second center in the global politics will allow Russia and the association to expand and diversify their cooperation and, in perspective, to develop it on the self-supporting and self-reproducing basis.

The Future of the Korean Peninsula: Topical Issues and Possible Solutions

Published: April 2019

The DPRK has become one of the most striking news-maker of 2018. Kim Jong-un took decisive steps to establish cooperation with the ROK – the parties had quite coordinated interaction during the Olympic Games in Pyeongchang, and hold three Inter-Korean summits in April, May and September 2018. Kim Jong-un have hold three meetings with Xi Jinping. The summit of Kim Jong-un and Trump in Singapore was equally resonant. The President of the Russian Federation during the WEF invited Kim Jongun to Russia, earlier the leader of North Korea had a meeting with S.V. Lavrov and V.I. Matvienko. These steps look  particularly important against the previous period, when the DPRK was mainly presented by the United States and other states as a security threat. However, despite the changes that took place and the fact that Kim Jong-un is attempting to build a dialogue in different areas, the position remains about the real interests and intentions of the DPRK and the future of the North Korean regime remains ambiguous. The article analyzes existing points of view on the issue and identifies and the prospects’ of the problem development. At the beginning of the study, a comprehensive analysis of the problem of the Korean Peninsula is presented. It examines the features of the interaction of the DPRK with key  international players, the question of sanctions against the country, and the peculiarities of the internal political line of the DPRK. Further analysis focuses on the current foreign policy line of Kim Jong Yin, assesses the results of major international meetings, including the opinion of experts and the analysis of the significance of specific agreements for understanding possible scenarios. Specific attention is payed to the Russian policy towards the inter-Korean settlement and Russian potential role in this process.
Inoculation of Potato Pulp with Antibacterial Lactic Acid Bacterium To Improve The Quality of Livestock Feed

Potato pulp was inoculated either with the antibacterial lactic acid bacteria Lactococcus lactis and L. diolivorans and the inoculated potato pulp was ensiled under anaerobic conditions for 30 d at room temperature in a mini-silo. We have previously reported that L. diolivorans produces antimicrobial peptides with potent antibacterial activity; therefore, the bacterium is expected to increase the fermentation quality of the potato pulp. The quality of the potato pulp silage was evaluated. The moisture content of the potato pulp silage was remained 822 g/kg before and after ensiling. The protein content in the silage increased from an initial concentration of 39 to 57 g/kg and 58 g/kg for L. lactis and L. diolivorans inoculations, respectively. The lactic acid content significantly increased from 2 to 52 g/kg (L. lactis) and 50 g/kg (L. diolivorans) after ensiling, whereas, toxic butyric acid was not detected with either treatment. These results suggest that the inoculation of potato pulp with L. lactis or L. diolivorans increases the quality and nutrition of potato pulp as silage. In particular, L. diolivorans is an efficient inoculant because it produces antibacterial peptides that prevent the increase of saprophyte in silage.
