Authors: Campos Maria Luiza de Almeida , Barbosa Nilson Theobald
Published: January 2021

Na atualidade, com todo o avanço tecnológico e a diversidade de repositórios, bases de dados e usuários e com a variedadede terminologias para o tratamento e a recuperação da informação, questões relacionadas à interoperação semântica secolocam. No âmbito da Ciência da Informação, um dos procedimentos para solucionar estes problemas de heterogeneidade,no que tange à diversidade de vocabulários existentes nos vários repositórios e bases de informações é o mapeamentosemântico. O mapeamento é o processo de estabelecer relações entre os conceitos de um vocabulário para outros e é usadolargamente para obter a interoperabilidade sintática e semântica nos SOCs. Neste artigo, a fim de endereçar tal problema,apresentamos a proposta metodológica de I. Dahlberg, na qual o mapeamento é o primeiro passo para que se possaidentificar o nível de compatibilidade entre os SOCs, denominados por essa autora de Sistemas Ordenados, com o propósitode permitir o uso comum dessas linguagens, quando forem efetuadas buscas em diferentes bases de dados ou quando sedeseja intercambiar informações indexadas com estas linguagens.

Os rankings universitários como sistemas de organização do conhecimento: considerações teóricas
Authors: Guimarães José Augusto Chaves
Published: January 2021

Considerando que os Sistemas de Organização do Conhecimento – SOC – constituem tradicionalmente o núcleo do campo disciplinar da Organização do Conhecimento, por permitirem o processo de representação, busca-se identificar e caracterizar os rankings universitários por meio da análise de sua natureza classificatória, valendo-se dos quatro rankings internacionais mais importantes: THE, Shangai, Leiden e QS a partir de suas notações, facetas, edições e formas de atualização, Os resultados confirmam que tais rankings atuam como SOC pois organizam um conhecimento para propiciar a geração de um novo conhecimento, mais específicamente como sistemas facetados de classificação permeados, como os demais SOC, por vieses culturais específicos Por outro lado, seu dinâmico processo de actualização permite uma constante remodelação de sua estructura, em consonância com a velocidade dos tempos atuais.

Oil Palm Empty Bunch Compost as a Source of Humic Acid
Authors: Oktavianta Irma D. , Gusrizal Gusrizal , Nurlina Nurlina
Published: January 2021

Humic acid is a fraction of humic compounds that are part of soil organic matter. In this research, humic acid is extracted from oil palm empty fruit bunches compost. Compost is made from the process of counting the empty oil palm bunches, which are composted until the compost is cooked. The humic acid extraction process uses a strong base extraction method. The principle of humic acid extraction is to dissolve the humic compound with a base solution and then separate it by adding an acid solution (HCl solution). The extraction of humic acid from oil palm empty fruit bunches compost produced blackish-brown humic acid with a yield of 4.895%. The result showed that the main functional group content of palm oil empty fruit bunches compost humic acid was the -OH group and phenol group which had a conjugated carbonyl group and a more aliphatic humic acid structure. Quantitatively, the functional groups of humic acid functional groups each amounted to a total acidity of 7,400 cmol/kg, a carboxylic group of 520 cmol/kg, and a phenolic -OH group content of 6,880 cmol/kg. Research results show that oil palm empty fruit bunches compost can be used as a source of humic acid.

Authors: Nirmalasari M. A. Y. , Bolly Yovita Y.
Published: January 2021

The use of inorganic fertilizer in the tillage was mostly used by Sikkanese. The reason was the large supply of inorganic fertilizer on the market, fast response, easy to absorb, and not to waste times. In the implementation, inorganic fertilizer was not used accordance with the stipulation of the four rights (4T): right dose, right time, right place, and right source. The result was the decrease of soil quality and the death of soil-degrading microorganisms so that the soil became infertile. Therefore, the booklet as a learning media gave the right information about the proper fertilization system. The research aims to know the appropriateness of the booklet development of inorganic fertilization system. The method used was the research and development (R n D) method by adopting a Borg and Gall model. The sample was taken by using purposive sampling. The analysis technical was validity analysis (valid percentage) and appropriate analysis (Widoyoko categorial). The result of the study showed that the booklet was appropriated to use as a medium of information for the farmer with the feasibility category both at the initial field trial and field trial stages. Furthermore, in the field trial implementation, the booklet was suitable to use with the very good feasibility category.
The Hadiya Case: Human Rights Violations and State Islamophobic Propaganda in India
Authors: Kalidasan Adhvaidha
Published: January 2021

This paper examines the “Hadiya case” which in the years 2016 and 2017 was well known throughout India and revolved around a woman, named Hadiya, her conversion from Hinduism to Islam and her marriage to a Muslim man. It caught the attention of the entire nation through intense coverage by the national media. The decision of Hadiya, who is an adult with her own conscience, to practice the religion of her choice and marry the person with whom she wishes to share her life, instigated a public legal debate. Hadiya’s case, which evoked Islamophobic and patriarchal ideologies, should be placed within the current political conditions of India. With regard to language, religion and ethnicity, India’s diversity under a right-wing political regime has been questioned, while the human rights of women, religious minorities like Muslims and Christians, dalits (lower caste people) and indigenous people from tribal communities have been violated. Paying close attention to the legal and logical reasoning of the Indian High Court during the year-long trial, this paper also evokes a critical perspective on the understanding of growing Islamophobia, hatred politics against Muslims and the violation of women’s rights, particularly of those from minority religious communities and lower castes in. Indian society is facing cultural dominance under the Hindutva ideology – an ideology that is intent on the dominance of Hindus and Hinduism. Such a cultural and ideological dominance can be seen in the everyday life of Indians, in legal systems, media institutions and other formal and informal organizations. As will become clear, such cultural politics were disguised in the form of legality in the Hadiya case.

A partir del contraste de percepciones, se pretende analizar la incidencia que pueden tener las prácticas didácticas en el interés por el área, y su potencial relevancia en la formación del pensamiento social e histórico del estudiante. El método utilizado fue el mixto; las muestras se recogieron a partir de dos encuestas, una aplicada a 10 profesores y otra a 661 estudiantes de grado 6.o, 9.o y 11.o en las cuatro instituciones educativas. El texto concluye que la enseñanza centrada en la trasmisión de contenidos es promotora del desinterés y que es necesario aprovechar los métodos de la investigación social e histórica para transitar hacia metodologías de enseñanza que promuevan la movilización de pensamiento social e histórico.
La región de Sumapaz y la guerra irregular en Colombia. Violencia Política 1948-2008
Authors: Pabón Quintero Wilson Rigoberto
Published: January 2021

La región de Sumapaz ha sido foco de organizaciones campesinas y de movilización social. Las diversas violencias, al igual que los procesos de paz de los distintos momentos en Colombia, se han manifestado allí. Lo que ha marcado la memoria de sus habitantes y la ha convertido en referente de estudios locales-nacionales e incluso globales sobre estos temas. De esta manera, desde los años cincuenta con la contienda bipartidista, pasando por la violencia del Frente Nacional y el conflicto armado interno, se desarrollaron prácticas violentas que se enmarcan en estrategias de guerra irregular, tan característica de los enfrentamientos políticos a nivel mundial durante la Guerra Fría. Todos los actores armados utilizaron métodos no convencionales para atacar a sus enemigos, lo que hace que la violencia en Colombia se haya manifestado de forma macabra y sea un referente permanente en los recuerdos de sus habitantes. Así, el presente artículo pretende entender la manera en que se manifestó la guerra irregular en un caso emblemático en el país, la región de Sumapaz, como epicentro de prácticas virulentas por parte de actores armados legales e ilegales desde mitad del siglo xx.

Bajo el pretexto de conocer un poco la experiencia del periodista Jesús Abad Colorado en el grupo de Memoria Histórica de la Comisión Nacional de Reparación y Reconciliación (CNRR), tuve la oportunidad de conversar con él en Bogotá en 2010, en un momento en el que hacía mi tesis doctoral y los trabajos con la memoria comenzaban a ganar en reconocimiento y protagonismo .

Este “narrador con imágenes” ha recreado la geografía de nuestra guerra, los rostros de la tragedia, pero también las esperanzas nacionales.

La conversación que sostuvimos por espacio de dos horas fue editada para facilitar su lectura y convertida en un breve relato, conservando la fidelidad de lo dicho.

Aunque nos separan casi 10 años de este momento, Jesús Abad me ha autorizado para circular lo conversado-narrado, por el valor que revisten sus valoraciones y apreciaciones en las circunstancias actuales del país.

Pteridine pigments compensate for environmental availability of carotenoids
Authors: Stuart-Fox Devi , Rankin Katrina , Lutz Adrian , Elliott Adam , Hugall Andrew , McLean Claire , Medina Iliana
Published: January 2021

Carotenoid-based colours are a textbook example of honest signalling
because carotenoids must be acquired from the environment. However, many
species produce similar colours using self-synthesised pteridine
pigments. A compelling but untested hypothesis is that pteridines
compensate for low environmental availability of carotenoids because it
is metabolically cheaper to synthesise pteridines than to acquire and
sequester carotenoids. Based on a phylogenetic comparative analysis of
11 pigment concentrations in skin tissue of agamid lizards, we show that
pteridine concentrations are higher and carotenoid concentrations lower
in less productive environments. Both carotenoid and pteridine pigments
were present in all species, but only pteridine concentrations explained
colour variation among species. Furthermore, pigment concentrations were
uncorrelated with indices of sexual selection. These results suggest
that variation among species in pteridine synthesis compensates for
environmental availability of carotenoids and challenge the paradigm of
honest carotenoid signalling in vertebrates with complex colour
production mechanisms.

Published: January 2021

Background: Pediatric B-Lymphoblastic lymphoma(pB-LBL) is a rare entity,
and appropriate treatment for pB-LBL is not well defined. While
intensive Acute Lymphoblastic leukemia(ALL) type regimens achieve long
term event free survival of 90% across western co-operative group
trials, published data from Asian studies on long term outcomes in
pB-LBL are scarce. We evaluated the outcomes and prognostic factors of
pediatric B-LBL patients treated at our center. Methods: We
retrospectively analyzed the data of pediatric B-LBL patients treated
between January 2010 and December 2017 on a uniform protocol(modified
BFM 90). Patients were evaluated for early response post-induction and
monitored for toxicity and long term outcomes. Kaplan-Meier method was
used to estimate the event free survival(EFS) and overall survival(OS).
Cox regression models were performed to identify prognostic factors.
Results: Of 21 patients who received treatment on the modified BFM 90
protocol, 17(81%) were alive in remission, 3(14%) had relapse, and
1(4%) had treatment-related mortality(TRM) while in remission. Two of 3
relapsed patients subsequently expired. With a median follow-up of 66
months(range 6–114), 5-year Event free survival(EFS) and overall
survival(OS) were 80%(95% CI:71–89%) and 91% (95% CI:85–97%),
respectively. While delayed presentation (≥3 months) had inferior
EFS(p-0.030), patients with elevated baseline Lactate Dehydrogenase(LDH)
had a worse OS(p-0.037). Age, gender, site of origin, stage, and
post-induction response had no bearing on outcome. Conclusions: Outcomes
of pB-LBL patients treated on modified BFM 90 protocol are excellent.
Higher disease burden manifested by elevated baseline LDH and delayed
presentation(≥3 months) portend poorer survival.

Detection rate of specific antibodies to the HCV CORE+1 protein in “naive” cronically HCV-infected patients in depends on the stage of liver fibrosis and the HCV subtype
Authors: Lichnaya E. V. , Belopolskaya M. A. , Verbov V. N. , Yakovlev A. A. , Dmitriev A. V. , Kalinina O. V.
Published: January 2021

Objective: The goal of this study was to examine the prevalence of anti-core+1 in “naive” patients with chronic hepatitis C and different stages of liver fibrosis infected by HCV subtypes 1b and 3a.

Materials and methods: A total of 86 “naive” patients (37 men and 49 women) with CHC observed in the Botkin infectious disease hospital in 2017, were included in this study. The average age was 50,7±2,7. Laboratory tests included ALT and bilirubin. In 53 patients, the fibrosis stage in the liver tissue was evaluated by the TE method using Fibroscan (Echosens, France). The presence of antibodies to the core+1 protein in blood serum samples was determined by the “inhouse” indirect ELISA method using synthetic peptides F10 and F13, which amino acid sequences correspond to the antigenic determinants of core+1 protein of the HCV subtypes 1b and 3a, respectively.

Results: In total, anti-core + 1 were detected in 27 (31,4%) subjects. It has been shown that the detection rate of anticore+1 does not depend on the HCV subtype. The study has indicated no statistically significant dependence between the presence of anti-core+1 and biochemical activity es of the infectious process (ALT, bilirubin). Anti-core+1 were detected in patients with all stages of fibrosis, however, the detection rate of anti-core+1 was statistically higher in patients with stage F4 fibrosis than in patients without liver fibrosis.

Conclusion: The obtained results suggest a possible role of the core+1 protein in the development of fibrosis. In the natural course of HCV infection, the detection of anti-core+1 can be considered as a prognostic marker for the progression of fibrosis in the liver tissue.
Predisposing factors contributing to the development of renal dysfunction in acute infectious diarrhea associated with hemocolitis (AIDH)

Outcomes of severe variants of acute infectious diarrhea in children with acute renal injury/failure (ARI/ARF) remain unsatisfactory, and mortality reaches 70% and more. ARI/ ARF therapy requires high material costs, which represent significant burden on health financing systems. It makes us consider AFR as one of the most important medical and social problems.

The aim of our studywas to investigate predisposing factors contributing to the development of renal dysfunction in acute infectious diarrhea associated with hemocolitis (AIDH), as well as to study the relationship of the developed renal dysfunction with the severity of endogenous intoxication, damage of vascular endothelium and hemostasis system.

We examined 60 sick children with AIDH, divided into two groups: with ARF and without kidney pathology.

Susceptibility to ARI/ARF in severe forms of AIDH is mediated by early childhood (up to 3 years in 89,5% of patients), artificial and mixed feeding (in 52,6% and 36,8% of children respectively), pathology of pregnancy in the first trimester, mother diseases during pregnancy (84,2%) and the late admission to hospital (89,5%) on the 4,9±0,2 day of the disease, i/m administration of furosemide without volume circulating blood restoration, i/m administration of nephrotoxic antibacterial medicines. Shigella spp. and Escherichia coli as etiologic factors of diarrhea in 42,1% and 47,4% of cases respectively. Thus due these parameters we can predict the loss of kidneys adaptation ability in diseases with severe course including acute infectious diarrheas.

Interrelationships between elevation of the number of antigen binding lymphocytes to tissue antigens of vascular endothelium up to 8,1±0,6% in children with ARF and development of hemorrhagic syndrome (decrease of PTI to 72,5%) and intensity of endogenic intoxication (average molecular peptides up to 9,7±0,6 g/l) and worsening of AFR signs were established.

Thus, it was found that AKI most often develops when rehydration therapy is started late or inferiorly performed, when nephrotoxic antibiotics and loop diuretics are prescribed without circulating blood volume (CBV) compensation and is accompanied by an increase in the degree of endogenous intoxication and vascular endothelial damage.

In Russia, Hemorrhagic Fever with Renal Syndrome (HFRS) takes the leading place among all natural focal infections, the incidence rate in 2018 was 3,99 per 100 thousand population. In the Northwestern Federal District of the Russian Federation, HFRS occurs much less frequently – 1,46 cases per 100 thousand population. The disease is more susceptible to men aged 16–50 years, children rarely get sick. In 2019, 73 cases of HFRS (1,36 per 100 thousand population) were registered in St. Petersburg, among them only 2 episodes – in children under 18 years of age. A clinical case of HFRS in a child aged 1 year and 8 months is presented. The diagnosis was established on the basis of clinical and epidemiological data (acute onset of the disease, the presence of fever, thrombohemorrhagic syndrome, oliguria, anuria, information on cases of HFRS at the place of residence of the child) and laboratory data (detection of specific IgM antibodies to the Hantaan virus) in the later stages of the disease. The described case should alert pediatricians regarding possible natural focal diseases, including HFRS. A thorough analysis of the anamnestic, epidemiological and clinical data of the patient will help in the early stages of the disease to suggest a diagnosis, conduct laboratory diagnostics and prescribe appropriate therapy.

Soul Restoration in Islamic Tradition (Ibn Tufail's Perspective of Tazkiyya an-Nafs Model)
Authors: Arroisi Jarman , Puspita Erva Dewi Arqomi
Published: January 2021

The modern era has had both positive and negative impacts on the progress of human civilization. The positive impact can be seen from the increasing advances in technology and science that help human life. Meanwhile, one of the negative impacts that emerged from the modern era is the spread of mental health problems in society. Not a few in modern society there are several symptoms and mental health problems that make it difficult for someone to find happiness. This article aims to explain efforts to cleanse the soul in Islamic tradition such as the pattern of cleansing the soul by Ibn Tufail. By using a descriptive critical analysis method with this type of literature research, this research found several important points. First, tazkiyya al-nafs is an important effort that must be made by someone to get a sense of happiness. Second, one of the important strategies and ways to get happiness according to Ibn Tufail is to attain knowledge of God. Third, if someone has come to the knowledge of God, then he will come to Ma'rifatullah. The attainment of this ma'rifatullah stage can only be achieved by someone if that person has cleansed his soul. With tazkiyya al-nafs that is done consistently one will come to what is called musyahadatullah or ma'rifah billah.
Nursi’s Sufism Without Sufi Order: A Centemporary Debate Among The Ulama
Authors: Munandar Siswoyo Aris , Sakhok Jazilus , Astuti Puji , Malikhaturrahma Elia
Published: January 2021

Some scholars think that people who take up religious beliefs are synonymous with being committed so that many people want to have tarekat. Even so, there are scholars like Badiuzzaman Said Nursi who think that tasawuf does not have to be committed. The statement of Sufism and sufi order according to Nursi is a way to recognize the nature of faith and the essence of the Qor’an to become a spiritual path under the guidance of the Prophet's sunnah. For Nursi, the spiritual activator is dhikr to Allah and continuous tafakkur to eliminate gloom, fear, and a sense of alienation from humans. The problem in this research is how the basic thoughts of Sufism Nursi and how the thoughts of Nursi about tasawuf without being committed. This study aims to determine the thoughts of Nursi about Sufism without any commitment. The results of this study are expected to provide a new understanding of the context of Sufism. This research is qualitative research that emphasizes library research. The type of approach carried out uses a socio-historical approach. Data collection was done by using the documentation method. Data analysis was performed using content analysis techniques. The analysis was carried out by proving the contents of the book, then analyzed and matched with existing data. This research also uses the method of interpretation (hermeneutic) so that Nursi's thoughts can be understood in a broader context and his childhood Nursi and his family adhered to the Nahsyabandiyah sufi order. Even so, Nursi stated firmly that he was not a follower of a sufi order. If the conventional view says that the nature path must be through sufi order, Nursi says: the nature path is sufficient through the Qur'an and following the behavior of the Prophet Muhammad. These characteristics can be used to describe al-Nursi's model of Sufism, namely sufism without sufi order. The results showed that Sufism without sufi order, according to Nursi, is someone who has sufism does not have to follow the teachings of a sufi order that has a teacher or murshid, only by always making dhikr glorifying the name of Allah, and always carrying out God's mandatory commands and sunnah so he will feel close God. I think Nursi thinking is something new that will make it easier for someone to be closer to Allah
Examining Semitic Rhetoric: A Qur’anic Sciences Perspective
Authors: Asnawi Aqdi Rofiq , Idri Idri
Published: January 2021

In his study of Qur’anic structure, Michel Cuypers applied Semitic Rhetoric that has been used to analyze Biblical structure. Despite having received positive responses from Gabriel Said Reynolds and others, Cuypers’ method was criticized by Nicolai Sinai for ignoring rhyme in the Qur’an and overdoing in maintaining the existence of the ring structure in the Qur’an. This paper, then, attempts to examine this analytic method from the perspective of the Qur’anic sciences’ (‘ulu>m al-Qur’a>n). This study aims to determine proportionally the characteristics of the method and the effect it produces by using descriptive-analytic and comparative research methods. This paper argues that there are subjectivity and inconsistency in dividing the text and determining the structure of its composition, as in the study of surah al-Qa>ri‘ah by Cuypers, and an ignorance of the information about reasons for the revelations (asba>b al-nuzu>l) and Prophet’s explanation about verses. However, the application of this method can lead to a new interpretation of the Qur’an, namely by using the information in the Qur’an itself, indicators of wording around it (siya>q), and verse correlation (muna>saba>t). On the other hand, this method supports the authenticity and coherence of the Qur’anic text, which has become a debate among the Orientalists.
Determination of the attenuation coefficients from the measured frequency characteristics of the windings of power transformers. Part 1. Theoretical consideration
Authors:   FSUE «RFNC-VNIITF named after Academ. E.I. Zababakhin», LARIN Vasily S. , MATVEEV Daniil A. ,   NRU «MPEI»
Published: January 2021

To model high-frequency processes and determine the stresses on the internal insulation of transformer windings, reliable high-frequency models of power transformers are required. The accuracy of modeling high-frequency resonance processes in the windings depends on how correctly the model reproduces the natural frequencies and damping of free oscillations in the windings. To construct and verify high-frequency models of power transformers, it is necessary to have experimentally obtained data on the values of damping factors. There is a known method for determining the winding damping factors based on measurements of the voltage transfer functions at the internal points of the windings and their subsequent processing using the vector fitting technique, but its application is not always possible in practice. The article presents the results of theoretical studies performed for a simplified transformer winding equivalent circuit. It is shown that the damping factors can be estimated from the width of the resonance peaks of the frequency responses of the voltage modulus and reactive component at the midpoint of the equivalent circuit, and from the input admittance resistive component and current in the neutral of the considered resonance circuit.
The Poynting Vector and the New Theory of a Transformer. Part 11. Three-Phase Three-Core Transformers without a Neutral Wire
Authors:   Peter the Great St. Petersburg Palytechnic University, SHAKIROV Mansur A.
Published: January 2021

A topological equivalent circuit for a three-phase three-core transformer reflecting the spatial structure of its magnetic system is developed. Owing to this approach, it became possible to represent the magnetic fluxes of the magnetic circuit’s all main sections and the apertures for each of three phases directly in the circuit in the absence of the windings’ neutral wires. The circuit is constructed by stitching together the anatomical circuit models of single-phase transformers obtained in the previous parts with taking into account the relationships between the fluxes at the junctions of the phase zones in iron. Its validity is confirmed by the rigor nature of the physical and mathematical relations for idealized transformers with infinite magnetic permeability of iron and simplified magnetic field patterns, which corresponds to the generally accepted approach with neglecting the magnetization currents. The difference lies in the fact that the developed model takes into account the heterogeneity of magnetization in different parts of the magnetic circuit with allocating more than 30 sections in the iron and apertures. The transition to the model of a real three-core transformer is carried out by adding four nonlinear transverse magnetization branches in each extreme phase zone and eight branches in the central phase zone to the idealized equivalent circuit. It is shown that in cases of winding connections without neutral wires, there is no flux of the Poynting vector in interphase zones in any unbalanced mode. In this case, the problems connected with the occurrence of fluxes exceeding the no-load fluxes under the conditions of symmetric and asymmetric short circuits, as well as the occurrence of buckling fluxes in these modes in the region outside the transformer iron, are solved.

During the operation of 0.4 kV electric networks, asymmetry of currents and voltages is unavoidable. As is known, unbalanced operation of 0.4 kV networks is stemming from nonuniform distribution of loads between the phases. This results in that a fundamental frequency zero-sequence current will flow through the neutral conductor in a four-wire three-phase electric network. On the other hand, during balanced operation of a four-wire electric network containing loads with a nonlinear volt-ampere characteristic, higher harmonic currents multiple to three are summed in the neutral conductor. Therefore, it is of relevance to analyze unbalanced operating conditions of a four-wire electric network containing loads with a nonlinear volt-ampere characteristic. The article presents the characteristics of a municipal load for analyzing unbalanced/nonsinusoidal conditions of its operation. For carrying out full-valued assessment of unbalanced operating conditions of a four-wire electric network, a simulation model of a 0.4 kV network section containing a nonsinusoidal load is developed. It is shown that during unbalanced operation of an electric network containing electric loads with a nonlinear volt-ampere characteristic it is recommended to take into account zero-sequence current higher harmonic components that are not multiple to three. An algorithm for calculating the neutral conductor current harmonic component for determining the cable temperature rating is developed.
polgári perrendtartás újragondolt alapelvei – elvárások és tapasztalatok
Authors: Dr. Molnár Tamás
Published: January 2021

Jelen tanulmány központi témája a magyar polgári perrendtartás kodifikációjának során újraszabályozott alapelvek egyes jellemzői. Elmondható, hogy az alapelvek száma és tartalma is koncentráltabb lett a kodifikáció eredményeképpen.

A polgári perrendtartásról szóló 2016. évi CXXX. törvény (továbbiakban: Pp.) számos koncepcionális változást hozott, ami az alapelvek tekintetében is megfigyelhető. Megújult a Pp. alapelvi fejezete, amelyben olyan elvek is rögzítésre kerültek, amelyeket a magyar polgári eljárásjog eddig még nem ismert. Jelen tanulmány áttekinti ezeket a változásokat és igyekszik állást foglalni az alapelvek tartalmát illetően is, külön vizsgálat tárgyává téve a jogalkotó által is kiemelt célkitűzésként megfogalmazott perkoncentráció elvét.

A dolgozat elemezni az alapelvekkel kapcsolatos szakmai vitákat, és megkísérel választ adni arra, hogy a hatályba lépés óta eltelt időszak tapasztalatai beváltották-e az alapelvi reformhoz fűzött egyes elvárásokat. A tanulmány vizsgálja a megváltozott szabályozást, amelyek a szakirodalomban is ellenkező álláspontok kialakulásához vezettek. Fontos témája a dolgozatnak, hogy az osztott perszerkezethez igazodóan a bíróság közrehatási tevékenysége is változáson ment keresztül. E változás az alapelvekben is megfigyelhető, mivel új alapelvként jelent meg a bíróság közrehatási kötelezettsége. Elemzésre kerül továbbá az igazmondás és a jóhiszeműség alapelvek egyes jellemzői.

A tanulmány igyekszik külföldi példákon keresztül megvilágítani a polgári perrendtartás alapelvi kérdéseit, amelynek során főként a német szabályozás egyes elemei kerülnek említésre.
bírósági jogkörben okozott kárért való felelősség és az ügyvédi felelősség összehasonlítása a felelősségi mérce szempontjából
Authors: Zsurzsa Zsolt
Published: January 2021

A tanulmány elsősorban a szerződésen kívüli károkozásért való felelősség egyik speciális alakzatára, a bírósági jogkörben okozott kárért való felelősségre koncentrál. Az utóbbi évek gyakorlata azt mutatja, hogy a bíróságokkal szemben indított kártérítési perek elhanyagolható hányadában marasztalják az eljárt bíróságokat a jogértelmezési vagy jogalkalmazási hibáikkal a feleknek okozott károk miatt. Indokolt ezért annak vizsgálata, hogy ennek a jelenségnek milyen okai lehetnek, valamint, hogy ezek az okok indokolják-e ezt a gyakorlatot. A vizsgálat eredményeként több olyan tényező is azonosítható, amelyek külön-külön is rendkívüli módon megnehezíthetnék a bíróságokkal szembeni igényérvényesítést, kombinálva pedig szinte lehetetlenné teszik azt. Ezen tényezők között elsősorban a kirívóan súlyos jogsértés doktrínáját, valamint a keresetet a jogerős bírósági döntések tartalmi immunitására hivatkozással elutasító ítéleteket lehet megjelölni.
Kutatásmódszertani szempontból célszerű volt a bíróságok kárfelelőssége kapcsán tett megállapításokat szembe állítani az ügyvédség kárfelelősségének bírói gyakorlatával, ahol egyértelműen megállapítható volt, hogy a bíróságok sokkal szigorúbb elvárhatósági mércét támasztanak, mint a bíróságokkal szemben, holott a két jogászi hivatásrend társadalmi felelőssége és munkaterhe ezt nem indokolná. Összehasonlításra került a két jogászi hivatásrend kárfelelősségének történeti kialakulása, a felelősségük jogszabályi háttere és a kapcsolódó joggyakorlat, rövid kitekintést téve külföldi példákra is. Az átfogó elemzés alapján javaslatok megfogalmazására kerül sor a jogalkalmazás és a jogalkotó számára is.
sérelemdíj funkció-analízise
Authors: Mátyus András
Published: January 2021

A 2013. évi V. törvény (Ptk.) – felválta a korábbi, elméleti és gyakorlati ellentmondásoktól terhes nem vagyoni kártérítés jogintézményét – a személyiségi jogok megsértésének önálló szankciójaként vezeti be a sérelemdíjat, mely kettős funkcióval bír: egyrészt célja az, hogy akit személyiségi jogában megsértenek, olyan pénzbeli juttatásban részesüljön, amely az elszenvedett nem vagyoni sérelmeket hozzávetőlegesen kiegyensúlyozza, kompenzálja. Másrészt magánjogi büntetésnek is tekinthető a hasonló jogsértések megelőzése érdekében, preventív jelleggel.
A cél szerinti értelmezés szerint a sérelemdíj csak akkor kerülhet alkalmazásra, ha az képes betölteni a funkcióját, vagyis ha nem mutatható ki olyan nem vagyoni sérelem, amely arányos jóvátételére (elsődlegesen) hivatott lenne a sérelemdíj, akkor egyáltalán nincs helye megítélésének, hiszen a személyiséget érintetlenül hagyó jogsértések esetében kizárólag a büntető funkció érvényesülne, ami teljesen összeegyeztethetetlen a magánjog eredendően helyreállító, kiigazító jellegével.
A jogirodalom egyöntetű véleménye szerint az elsőbbség a kompenzációs funkcióé kell, hogy legyen és csak másodlagos helyet foglalhat el a magánjogi büntetés jelleg. Munkám alapján elmondható, hogy sérelemdíjra a bírák is elsősorban az elszenvedett immateriális sérelmeket orvosló, az elveszett életörömök pótlására szolgáló jogintézményként tekintenek és azt kizárólag preventív céllal nem ítélik meg, hanem az esetek döntő részében a prevenciós funkció a marasztalás összegét emelő tényezőként kerül értékelésre.
Tanulmányomban több szempontból kívánom elemezni, hogy a sérelemdíj kettős funkcióját a bíróságok hogyan értékelik az előttük fekvő ügyekben, melyik jelleg domborodik ki az összegszerűség és melyik a jogalap kapcsán. Lévén a kutatás alapvetően empirikus jellegű, ezért minél több ítélet feldolgozásán keresztül vizsgálom, hogy, milyen szempontokat értékel a judikatúra a kompenzációs (pl.: elszenvedett testi sérülések, lelki változások, életkor, a sértett családi élete, életvitel megváltozása stb…) és milyen szempontokat a prevenciós funkció (pl.: jogsértés súlya, elhúzódó jellege stb…) keretében. Végül meg kívánom válaszolni dolgozatom központi kérdését, vagyis: milyen funkciót tulajdonít a gyakorlat a sérelemdíjnak.

Tujuan pelaksanaan kegiatan pengabdian ini yakni meningkatkan pengetahuan dan pengalaman masyarakat lokal dalam memetakan potensi desa, khususnya produk unggulan kawasan pedesaan (Prukades). Untuk berikutnya, hasil pemetaan Prukades tersebut dapat dijadikan pengembangan usaha BUMDes di Pekon Sukabanjar. Metode PkM mencakup tiga tahapan, yakni (1) tahapan pendekatan, mulai dati upaya peningkatan aspek kognitif terhadap peserta PkM hingga tahap pendampingan dan pemberdayaan; (2) tahapan pekerjaan, yakni identifikasi faktor kekuatan dan kelemahan dalam upaya menemukenali potensi desa-Prukades; dan (3) tahapan tindak lanjut program. Mengacu dari hasil pelaksanaan PkM terungkap bahwa keberadaan BUMDes di Pekon Sukabanjar belum berdampak secara optimal meningkatkan kesejahteraan masyakat sekitar. Setidaknya kendala terbesar terletak pada masih lemahnya aspek tata kelola pengelolaan BUMDes di pekon tersebut. Adapun hasil pemetaan prukades di Pekon Sukabanjar mencakup: (1) keunggulan hasil pertanian yakni alpukat, kopi, singkong, sayur mayur, dan peyediaan bibit tanaman, dan (2) keunggulan potensi wisata mencakup jasa angkutan wisata air Danau Ranau, pemandian air panas di kaki Gunung Seminung, hingga ziarah tempat keramat/suci. Rekomendasi hasil PkM ini menekankan pada prukades yang dimiliki oleh pekon dapat dijadikan pengembangan jenis usaha pada BUMDes di Pekon Sukabanjar.
Transformation Of Social And Economic Livelihoods Of Rubber Farmers
Authors: Kasdi Muh Fajrin
Published: January 2021

Rubber production in Bulukumba Regency continues to increase the amount of production every year, to be precise in Bulukumpa District, Batulohe Village. But in fact, the life of rubber farmers is still very far from prosperous. The novelty of this research is to try to capture the livelihoods of rubber farmers from sociological and economic aspects. The purpose of this study was to determine the structure of land tenure, wage levels, education levels, access to information, and trade value chains in Batulohe Village, Bulukumpa District. This research was conducted in Batulohe Village, Bulukumpa District, Bulukumba Regency. This type of research is qualitative ethnographic in nature, this model seeks to study cultural events, which present the subject's view of life as an object of study. The data source of this research comes from direct interviews with rubber farmers. Data processing and data validation techniques used were source triangulation techniques to test the validity of the information obtained from informants. The results showed that there was no imbalance in land tenure structure because in fact the community already owned land. The level of wages given to farm laborers is not proportional because it does not follow the prevailing rubber price trend. The education level of farmers is still relatively low. Meanwhile, existing access to information is not transparent and unequal because it is monopolized by traders at both the village and city levels. Finally, the trade chain that occurs involves several actors, starting from farmers, village traders, urban traders to the processing industry, which tends not to benefit farmers. A big push intervention policy from the government is needed so that there will be a redistribution of fiscal allocations to the poor and an improvement in livelihoods and income. Keywords: Rubber Farmers, Social Economic; Welfare.

Proposed Innovative Correlations for some Nuclear and Radiological Fields using Theorem of S. El-Mongy
Authors: El-Mongy Sayed
Published: January 2021

Thinking and thought are divine urge in the Great Quran. The published S. El-Mongy theorem (L= eπrsA) correlates eπ with radius r of circular and spherical geometries by a factor sA (θ/10ϕ) to be used for calculations of arc length and astronomical distance. In this article, Sayed’s formula was used to produce correlations with the well-established laws and formulas of different nuclear and radiological fields. The formula was directed to be correlated with half-life time, activity, flux, reaction rate, reactor power, mean free path, photon fluence rate, radiation dose rate and half value thickness equations. It was also oriented to calculate fuel rods circumstances of different reactor types; PWR, BWR, VVER1200 and Candu-6. The produced correlations of eπ and sA with the above mentioned topics are given with simplified reduced forms, limitation and some comparative calculations between old and the proposed innovative formulas. New formulas for sphere volume and surface area and cylinder are also given based on eπ term.
Evaluation of the expression of hexokinase 1, glucokinase, and insulin by canine insulinoma cells maintained in short-term culture
Authors: Suwitheechon Orn-usa , Schermerhorn Thomas
Published: January 2021

OBJECTIVE

To develop a technique for isolation and culture of canine insulinoma cells and assess expression of cellular hexokinases (glucokinase and hexokinase I) and expression and secretion of insulin from these cells in vitro.

SAMPLE

Pancreatic insulinomas and normal pancreatic tissue from 4 and 3 dogs, respectively.

PROCEDURES

Tissues were collected by surgical excision or at necropsy. Insulinoma cells from 2 dogs were cultured for up to 10 weeks with standard techniques; insulin synthesis in vitro was confirmed by immunohistochemical analysis of freshly prepared slides of cultured cells, and insulin secretion was assessed by measurement of insulin concentrations in culture medium with an ultrasensitive mouse insulin ELISA. Expression of cellular hexokinases in insulinomas and adjacent normal (nontumor) pancreatic tissue from the same dog (n = 3) was examined by quantitative reverse transcriptase PCR assay.

RESULTS

Insulinoma cells survived for up to 10 weeks but did not proliferate in culture. Insulin was detected in isolated cells and secreted into culture medium for up to 10 weeks. Both cellular hexokinases were expressed; glucokinase appeared to be overexpressed in insulinomas, compared with normal pancreatic tissue from the same dogs.

CONCLUSIONS AND CLINICAL RELEVANCE

Canine insulinomas expressed hexokinases responsible for glucose responsiveness. Insulinoma cells were successfully maintained in short-term culture; cultured cells remained functional for 10 weeks as evidenced by cellular insulin content and had detectable secretion of insulin into the culture medium for ≥ 5 weeks. Apparent glucokinase overexpression by insulinomas suggested a possible mechanism underlying excessive insulin release by these tumors.
