The study attempted to assess the water quality around paper mill effluents discharge areas. Several physicochemical parameters and the Canadian Council of Ministers of the Environment (CCME) Water Quality Index (WQI) were considered to determine the pollution level of surface and groundwater in the selected paper mills areas located in Saidpur, Gobindaganj, and Dupchanchia Upazilas of Bangladesh. Physicochemical characterization of the surface water around the paper mills areas showed that the concentration of EC, TSS, BOD5, COD, phenols, NO3−-N, and K+were exceeded the surface water standard, whereas the DO level ranged from 1.63 to 3.5 were found below the Environmental Conservation Rules (ECR), 1997 standard. Besides, the BOD, COD, and Mn ion concentrations of groundwater exceeded the drinking water standard. In most sampling sites, the WQI of the surface water showed ‘marginal’ category, and the groundwater quality showed 'fair' category. The study observed that the toxic effluents discharged from the paper mills caused harm to the aquatic ecosystem.

«Memories of a Caucasian Officer», the main work of Fjodor Tornau
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Avidzba Regina L.
Published: October 2021

The article provides an overview of Fjodor Tornau in the context of studying the Caucasus in the 19th century. Special attention is paid to the main book of the writer — “Memories of a Caucasian Officer”, created on the basis of the author’s own experience as a scout. The history of the publication of “Memories ...” testifies to the genuine interest of readers in the exciting story of Fjodor Tornau’s stay among the mountaineers in captivity and several escapes from capture. However, the storyline is far from the main advantage of the book, which has become a tabletop for several generations of Caucasian scholars. Fjodor Tornau managed to collect extremely rare material. Russian ethnography, historiography, physical geography and related branches of knowledge were significantly enriched by unique materials compiled on the basis of personal observations by Fjodor Tornau, with numerous details of military operations in the Caucasus; individual observations of the scout writer have no analogues in the science of the Caucasus. Fjodor Tornau’s undoubted literary talent and natural artistic talent manifested itself in his stylistic manner, which attracts the most sophisticated connoisseurs of the word.
Hieromonk Arseniy (Worldly Aleksandr Minin) — Founder of the New Athos Monastery Named After Simon the Canaanean
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Shcherbakova Marina I.
Published: October 2021

The article presents an outline of the life of Hieromonk Arseniy (worldly Aleksandr Minin) — founder and first builder of the New Athos Monastery named after Simon the Canaanean. According to the preserved sources, his path is traced, which preceded the trip to Athos. Upon arrival at the Holy Mountain of Athos, Aleksandr Minin carried out various assignments of the elders in the monastery. The return to Russia was associated with a new taking of God’s orders by collecting donations for Panteleimon Russian Monastery on Athos. Vigorous activity about Arseny consisted in the arrangement of a permanent monastery courtyard in Moscow, a chapel, where the Athonite shrines brought by him were preserved. Fr. Arseny stood at the origins of the publishing activity of the Athos Saint Panteleimon Monastery, founded in 1878 in Moscow its periodical “The Soul-Saving Reflections” (“The Soul-Saving Interlocutor”). He himself wrote a lot, mainly spiritual and moral instructions, instructive letters. In the mid- 1870s Fr. Arseniy’s taking of God’s orders was supplemented with one more, more difficult one — the response to the oppression of the Russian monks on the Holy Mountain, he was instructed to find a place on the Black Sea coast where a monastery could be built, a certain prototype of Russik, where its monastic traditions and Rule would be observed. Fr. Arseniy found such a place near Sukhumi, where there was a destroyed church in the name of St. the Apostle Simon the Canaanean. In 1875 the dispensation of the New Athos Monastery named after Simon the Canaanean began. For the history of the monastery, information about its founder is of absolute value.

Abkhaz lectures by Anatoliy Genko
Authors:   Institute of Ethnology and Anthropology, Anchabadze Yuri D. ,   D. I. Gulia Abkhazian Institute for Research in the Humanities, Abkhazian Academy of Sciences
Published: October 2021

The article provides a brief overview of the main stages of development and increment of scientific knowledge about Abkhazia, describes the most important achievements in the field of collecting, source research and systematization of the material. It is noted that, in General, abkhazov studies have not reached the completeness and abundance of publications that are typical for other regional sections of Russian kavkazov studies. This indicates the relevance of studying the scientific heritage of Anatoly Nestorovich Genko, an outstanding scientist, linguist, ethnologist, and kavkazologist. The main attention is paid to Genko’s lectures delivered in the autumn semester of 1940 to students of the ethnographic Department of the Geographical faculty of Leningrad University. The lecture course on Ethnography of the peoples of the Caucasus consisted of twenty lectures, two of which were devoted to Abkhazia. The article describes the structure of the course, the author’s methodology and techniques. It is noted that, choosing an example from the phenomena of everyday culture, Genko considered it in more detail, in detail, and, as a rule, extrapolating to the entire Caucasus, within the framework of regional specifics as an element of the Caucasian civilizational universe. The problems formulated by Genko related to the study of the history, religion, and Ethnography of Abkhazia were aimed at identifying the most striking features of the region. Lectures abound with rare material related to the manifestations of ancient ethnic traditions, Patriarchal features of Abkhazian life, and the specifics of national culture, which makes them relevant today.

A luz no cinema, Fabrice Revault d´Allonnes
Authors: D´Artemare Antoine , Freitas Bruna
Published: October 2021

Encontra-se aqui a tradução do primeiro capítulo do livro La lumière au cinéma (1991), do teórico francês Fabrice Revault d’Allonnes. Neste livro, o autor desenvolve uma reflexão teórica sobre a questão da iluminação no cinema, elencando seus diferentes regimes e suas diversas funções. Ele também retraça um panorama histórico da direção de fotografia, assinalando as diversas inovações decorrentes de mudanças tecnológicas ou estilísticas. Inédito em língua portuguesa, o livro é uma referência para os estudos de direção de fotografia. Neste primeiro capítulo aqui traduzido, Revault cunha dois conceitos para a análise da luz no cinema: o de “iluminação clássica” e o de “iluminação moderna”. Se o autor inscreve essas noções em um quadro histórico em que esses tipos de iluminação emergem, ele, no entanto, não as restringe a determinados períodos da história do cinema. Esses conceitos dizem respeito, antes de tudo, à possibilidade de significar ou não através da luz. Para o autor, a luz clássica é aquela expressiva, dramatizada, teatral, metaforizada, que carrega luminosamente um sentido pleno e transparente em conflito com o mundo. Nesse primeiro regime, faz-se falar a luz, expressa-se através dela. Por outro lado, é a luz moderna que, como argumenta o autor, possui uma essência documental, inexpressiva, não dramatizada, recusando-se a produzir sentido e indo ao encontro, dessa forma, da insignificância da luz no mundo e de seu caráter absurdo. Trata-se de uma reflexão sobre as possibilidades de produção de sentidos através da luz no cinema que possui, ainda hoje, grande relevância.
La erotización del nazismo en el cine de autor italiano. Un acercamiento al ciclo sadiconazista a partir de “Il portiere di notte” (Cavani, 1974)
Authors: Pagés Natalio
Published: October 2021

Como señaló Susan Sontag, la erotización del nazismo refiere a la producción de imágenes fascinantes sobre la iconografía o el proceso concentracionario nacionalsocialista en discursos de la cultura masiva. Aunque se encuentra asociada comúnmente a la producción de posmemoria durante la posguerra, la “erotización” es un esquema representacional que puede rastrearse desde la literatura modernista europea de los años treinta hasta la producción cinematográfica contemporánea. Sin embargo, uno de sus picos de notoriedad y consolidación de rasgos discursivos —que luego se expandirá a la literatura de bolsillo y el exploitation, al comic y las novelas gráficas, al cine mainstream norteamericano de los años ochenta y el cine de género de las últimas décadas— ha sido una serie de largometrajes italianos de los años setenta —denominados posteriormente “ciclo sadiconazista”— conformado por obras de autores reconocidos como Visconti, Cavani, Wertmüller, Brass y Pasolini. Este artículo se dedica a analizar en detalle los motivos temáticos y las operaciones retóricas y enunciativas de Il portiere di notte (Cavani, 1974) intentando asir los rasgos comunes del ciclo sadiconazista, como primer paso hacia un objetivo mayor: comprender los efectos de la erotización en la producción de memoria sobre el genocidio nazi.
Intrigas políticas, tramas escópicas: Eastwood, De Palma e as artimanhas do poder
Authors: Oliveira Junior Luiz Carlos
Published: October 2021

Poder absoluto (Abolute Power, 1997), de Clint Eastwood, e Olhos de serpente (Snake Eyes, 1998), de Brian De Palma, possuem elementos em comum e pertencem ao mesmo período histórico, mas desenvolvem perspectivas distintas sobre o tema da conspiração política, de acordo com as visões de mundo e as preferências estilísticas de seus realizadores. O artigo analisa ambos os filmes a partir das estratégias adotadas por eles para compor dispositivos de reflexão sobre o olhar, o ponto de vista e a dimensão política dos atos de observar e vigiar.
Notas sobre (in)visibilidade dissidente e políticas públicas no audiovisual brasileiro
Authors: Pinto Bravo Juliana Ribeiro
Published: October 2021

O presente artigo tem o objetivo de refletir sobre a representatividade de sujeitos dissidentes no audiovisual brasileiro, a partir da perspectiva de políticas públicas de incentivo e fomento ao setor. Considerando o boom da produção independente no país após a criação da Lei 12.485/11, impulsionado pelas cotas de tela e novas linhas de financiamento para cinema e TV, propõe-se neste trabalho ponderar sobre medidas e mecanismos que possibilitam uma discussão sobre a noção de diversidade: a existência ou invisibilidade de sujeitos e corpos LGBTQIA+ e queer nas obras audiovisuais brasileiras.
Fisuras, desvíos y transgresiones a las leyes de los machos. Masculinidades en O menino e o vento y A intrusa de Carlos Hugo Christensen
Authors: Gil Mariño Cecilia Nuria
Published: October 2021

El presente trabajo propone abordar dos obras sumamente diferentes en cuestiones genéricas, estéticas y temáticas del cineasta argentino radicado en Brasil Carlos Hugo Christensen, para analizar las desestabilizaciones a las matrices culturales binarias de las imágenes de lo masculino y lo femenino a través de la puesta en escena de sexualidades que desafían a la heteronormatividad. Estos filmes son O menino e o vento(1966) y A intrusa(1979). Con este objetivo, se plantea, por un lado, analizar el rol del paisaje como metáfora de la libertad u opresión para el delineamiento de subjetividades que ponen en cuestión las relaciones de poder de las masculinidades y sus categorías. Por el otro, se indagará sobre los procesos de tensión entre la transgresión y la ley, el deseo y la condena, de estas figuras masculinas frente a los tribunales del patriarcado que adoptan características muy distintas en ambas películas. Explorar ambos filmes en diálogo pone de manifiesto el trabajo estético sobre los universos genéricos y el tratamiento del espacio para plantear desde la cultura de masas fisuras, desvíos y transgresiones a las leyes de los machos y las relaciones de poder de las masculinidades.
Relação entre Desempenho Econômico-financeiro e Performance Esportiva dos principais Clubes de Futebol do Estado de São Paulo
Authors: Lima Batista Elvis , Da Silva Cajaiba Kleber
Published: October 2021

Esta pesquisa teve como objetivo analisar se indicadores econômico-financeiros dos principais clubes de futebol do estado de São Paulo estão atrelados aos resultados esportivos conquistados por essas agremiações. A metodologia propôs o estudo de correlação entre as variáveis independentes: Receita Bruta; Despesa com Salário; Ebit; Endividamento; e a variável dependente: ranking CBF, ao testar duas hipóteses; a H0: Não existe correlação estatística significante entre indicadores financeiros e desempenhos esportivos dos principais clubes de futebol paulistas; e, a H1: Existe correlação estatística significante entre indicadores financeiros e desempenhos esportivos dos principais clubes de futebol paulistas, por meio da ferramenta estatística ‘Correlação de Spearman’. Os principais achados mostraram que, especificamente para Palmeiras e Corinthians, maiores receitas guardaram correlação com melhores resultados esportivos, da mesma maneira que menores receitas guardaram correlação com piores resultados esportivos. Todos os demais resultados não se apresentaram estatisticamente significantes, quando testados ao nível de significância de 5%, ou inferiores. Assim, não se pôde afirmar que maiores despesas com salários; melhores marcadores EBIT e maior ou menor endividamento estivessem correlacionados a melhores ou piores performances esportivas dos clubes da amostra. Assim, não se pôde rejeitar a hipótese H0. Os principais clubes do estado de São Paulo, especificamente, não apresentaram comportamento isolado diverso de estudos anteriores que englobavam amostra nacional.

Published: October 2021

Este artigo tem como objetivo analisar as contribuições freirianas para a Formação Continuada de professores/as da Educação Infantil, de uma universidade estadual pública baiana, em um contexto pandêmico. Para tanto, optamos por uma pesquisa com abordagem qualitativa, do tipo exploratória e descritiva. Utilizamos o questionário virtual (Google Forms) para produzir os dados e contamos com a participação de 26 pós-graduandos/as, sendo 25 mulheres e 1 homem.  Os dados revelam que embora a pandemia tenha trazido diversos desafios para os/as professores/as em formação continuada, também possibilitou novas aprendizagens, superação de sentimentos, medos, exigiu mais dedicação etc. Além disso, os questionários nos mostram que algumas palavras geradoras das obras freirianas se fazem presentes nas respostas dos/as colaboradores/as da pesquisa, como: autonomia, dialogicidade, conscientização, libertadora, humanização, reflexão crítica, cidadão, entre outras. Posto isto, observamos que Paulo Freire contribuiu para os/as professores/as terem um olhar mais sensível, compreenderem o desenvolvimento humano, verem a educação como lugar de troca de aprendizagens entre docentes e discentes, isto é, lugar de preparação para a vida.
GESTÃO DEMOCRÁTICA DA ESCOLA: REFLEXÕES A PARTIR DA PRÁTICA DE LIBERDADE EM PAULO FREIRE
Authors: Ferreira Maria Jucilene Lima , Santos Júnior Paulo A.
Published: October 2021

Neste artigo trata-se do conceito de gestão democrática da escola e suas relações com o conceito de prática de liberdade em Paulo Freire, considerando-se a seguinte indagação: Em que medida a concepção e os princípios subjacentes às proposições de gestão democrática na “Proposta de gestão escolar para o trato com a diversidade” para uma escola pública no interior do Estado da Bahia-Brasil dialogam com a perspectiva da prática de liberdade em Paulo Freire? Propõe-se refletir sobre os processos de gestão escolar de perspectiva crítica, relacionando os princípios apresentados na proposta de gestão de uma escola pública na Bahia-Brasil com a concepção de educação em Freire. O caminho metodológico pauta-se pela pesquisa bibliográfica e documental articulada à análise de um plano de gestão escolar de perspectiva democrática, crítico-libertadora. Os resultados apontam características da gestão e suas relações com prática de liberdade. Conclui-se que a administração/gestão escolar, desde que seja assumida nos termos apresentados, quais sejam, de respeito aos sujeitos partícipes do cotidiano escolar, assumindo os princípios e práticas de descentralização de poder na escola, concorre para a desconstrução de práticas pedagógico-administrativas alienantes e, por isso, desumanizadoras.

Violência contra adolescentes: fatores associados, manifestações e enfrentamento
Authors: Costa José Ronildo da , Magalhães Beatriz de Castro , Silva Mauro Mccarthy de Oliveira , Albuquerque Grayce Alencar
Published: October 2021

Objetivou-se identificar na literatura fatores associados, manifestações da violência e estratégias de enfrentamento à violência contra adolescentes. Trata-se de uma revisão não sistemática da literatura, em que realizou-se levantamento de artigos em bases e biblioteca de dados com os descritores em ciências da saúde: "saúde do adolescente", "vulnerabilidade social" e "violência". Aplicaram-se como critérios de seleção: textos completos em idioma português, inglês e espanhol; publicados entre 2011 a 2020 sendo descartados artigos repetidos, indisponíveis gratuitamente e sem relação com a temática. Identificou-se 129 artigos, onde 67 foram utilizados na construção. Os dados foram analisados conforme a literatura pertinente. A vulnerabilidade e dependência, próprias da faixa etária, elevam a susceptibilidade de adolescentes àS violências, principalmente em meios de menor nível socioeconômico, afetando o contexto familiar e ambiental na qual está inserido. As consequências, muitas vezes invisíveis, podem se perpetuar até a fase adulta, com sentimentos de desvalorização, baixa autoestima, depressão, ansiedade, comportamento suicida, isolamento social, consumo de álcool e drogas, dentre outros. Denota-se a necessidade de políticas públicas que direcionem ações de prevenção e enfrentamento da violência, principalmente pelas escolas, uma vez que é neste espaço que adolescentes podem ser assistidos de forma individual e coletiva, e com apoio das equipes de saúde, para suporte físico e emocional aos adolescentes.

Risk Factors of Childhood Cancer in Armenia: A Case-Control Study
Authors: Avagyan Manushak , Abrahamyan Lusine , Demirchyan Anahit
Published: October 2021

Background: Childhood cancer (CC) is a leading cause of death among
children aged 0-19 years worldwide. Each year, 400,000 new cases of CC
are diagnosed globally. Given the between-country differences in CC
incidence rates, types and trends, this study aimed to identify possible
risk factors for CC in Armenia. Methods: We used a case-control study
design by enrolling participants from the only specialized pediatric
hematology and oncology center in Armenia. Cases included patients ≤14
years old diagnosed and treated with a malignant disease between
2017-2020 in the centre. Controls included patients diagnosed and
treated in the center during the same period for a non-malignant
disease. We conducted telephone interviews with mothers of cases and
controls. Independent risk factors of cancer were identified using
multivariable logistic regression analysis. Results: Overall, 234
participants (117 cases, 117 controls) were included in the study. Based
on the fitted model, maternal usage of folic acid during pregnancy was
protective against CC, almost twice decreasing its odds (OR=0.54; 95%
CI: 0.31-0.94). On the contrary, experiencing horrifying/terrifying
event(s) during pregnancy (OR=2.19; 95% CI: 1.18-4.07) and having
induced abortions before getting pregnant with the given child (OR=2.94;
95% CI: 1.45-5.96) were associated with higher odds for a child to
develop cancer. Conclusion: This study identified three important
modifiable risk factors for CC in Armenia, all related to the period of
pregnancy. The findings indicate the importance of education on stress
reduction during pregnancy, the use of folic acid prior to and during

Objective Programmed intermittent epidural bolus (PIEB) was reported to
provide superior maintenance of labour analgesia with better pain
relief, and less motor block than continuous epidural infusion (CEI).
Whether this is also evident for uterine contraction pain relief after
caesarean section remains unknown. Design Randomised, double blind,
positive-control trial. Setting Guangzhou Women and Children’s Medical
Center, China Population Parturients scheduled for elective caesarean
section under combined spinal-epidural anaesthesia were enrolled.
Methods At the end of the surgery, after a similar epidural loading dose
given, patients received either PIEB (6 mL every hour) or CEI (6 mL/h)
of 0.1% ropivacaine. Main outcome measures The primary outcome was the
effectiveness of uterine contraction pain relief during breastfeeding
assessed with visual analog scale score (VAS-UD) at the postoperative 36
h. Secondary main outcome was lower extremity motor block (defined as
Bromage score > 0). Results One hundred and twenty
parturients were studied (PIEB, 60; CEI, 60). The VAS-UD at the
postoperative 36 h was significantly lower in the PIEB group than in the
CEI group [median (IQR), 30 (20 to 40) mm] compared with the CEI
group [40 (30 to 50) mm], with an estimated difference of -10 mm
(95% CI -15 to -5 mm; P=0.001). Motor block was higher in the CEI group
than in the PIEB group during the study period except 2 h (all
P<0.05). Conclusions PIEB provides more effective uterine
contraction pain relief and less motor block after caesarean section
than CEI.

Background: Cryoballoon (CB) based pulmonary vein isolation (PVI) has
proven to be as effective as radiofrequency (RF) based ablation.
Different ablation protocols took the individual time-to-isolation (TTI)
into account aiming at shorter but equally or even more effective
freeze-cycles. The current study sought to assess the impact of the TTI
on PVI durability in patients undergoing a repeat procedure for
recurrence of atrial tachyarrhythmia (ATA). Methods and Results: In 205
patients with ATA recurrence after previous CB-based PVI a total of 806
PVs were identified. One hundred-twenty-six out of 806 PVs (16%) were
previously treated with a TTI guided ablation (protocol #1; TTI+120
sec.), in 92/806 (11%) PVs TTI was only monitored (m) but fixed
freeze-cycles were applied (protocol #2; mTTI) and in 588/806 (73%) a
fixed freeze-cycle was applied without TTI-monitoring. There was no
difference in the PV-reconduction rate between the groups (P=0.23). The
right inferior pulmonary vein (RIPV) showed overall significantly higher
reconduction rates compared to the other PVs (RIPV – left inferior PV
(LIPV) p<0.003, -left superior PV (LSPV) p<0.001, -
right superior PV RSPV p<0.013). In 21 patients (10%) only
for the RIPV reconduction was assessed. Conclusions: TTI based CB
ablation did not show significant differences regarding PV-reconduction
rates compared to the other protocols.

A case of severe Epstein-Barr viral hepatitis with the development of hepatic cell failure and encephalopathy in a 1-year old child
Authors: Kramar L. V.
Published: October 2021

Objective: The article describes a clinical case of severe Epstein-Barr viral hepatitis in a child aged 1.

Materials and methods. The diagnosis of Epstein-Barr mononucleosis was confirmed by repeated isolation of Epstein-Barr virus DNA from the blood by PCR, and IgM to the capsid antigen detection in the blood. Atypical mononuclear cells in blood tests were not detected throughout the disease course.

Results. The main clinical symptoms in the first 2 weeks of the disease included a fever, severe lymphoproliferative syndrome, persistent purulent tonsillitis, and maculopapular rash. Severe hepatic damage developed on 20th day from the onset of the disease. The fact that the disease had an unusually severe course made it necessary to conduct differential diagnosis with lymphoproliferative and hemophagocytic syndromes. The child received the treatment with low-dose interferon agents (interferon α-2b) in suppositories, glucocorticoids (prednisone 3 mg/kg/day), intravenous immunoglobulins, symptomatic therapy. Acyclovir therapy was not administered. The patient made a complete recovery with full normalization of liver function.

In the attempt to understand the origin of autoantibody (AAb) production in patients with and at risk for type 1 diabetes (T1D), multiple studies have analyzed and reported alterations in T follicular helper (Tfh) cells in presymptomatic AAb+ subjects and patients with T1D. Yet, whether the regulatory counterpart of Tfh cells, represented by T follicular regulatory (Tfr) cells, is similarly altered is still unclear. To address this question, we performed analyses in peripheral blood, spleen, and pancreatic lymph nodes (PLN) of organ donor subjects with T1D. Blood analyses were also performed in living AAb− and AAb+ subjects. While negligible differences in the frequency and phenotype of blood Tfr cells were observed among T1D, AAb−, and AAb+ adult subjects, the frequency of Tfr cells was significantly reduced in spleen and PLN of T1D as compared with nondiabetic control subjects. Furthermore, adoptive transfer of Tfr cells delayed disease development in a mouse model of T1D, a finding that could indicate that Tfr cells play an important role in peripheral tolerance and regulation of autoreactive Tfh cells. Together, our findings provide evidence of Tfr cell alterations within disease-relevant tissues in patients with T1D, suggesting a role for Tfr cells in defective humoral tolerance and disease pathogenesis.
The Investigation of microstructure evolution in electron beam additive manufacturing by phase field method
Authors: Ai Yuewei , Huang Yi , Yu Long , Liu Xiaoying
Published: October 2021

The mechanical performance of the components is highly related to the microstructure characteristics in the electron beam additive manufacturing (EBAM). The solidification process with complicated behaviors during the EBAM plays a major role in the microstructure formation. This paper is focused on the dendrite evolution in the solidification process of the EBAM of Ti-6Al-4V. A phase field model coupled with macroscopic solidification of molten pool which takes the heat transfer of molten metal and transient temperature field into consideration is proposed. The microstructure evolution and solute field distribution about columnar crystal are analyzed quantitatively. The simulated results are compared with that from the analytical model and good agreement between them has been found. It is demonstrated that the evolution of microstructure is mainly determined by the temperature gradient and solidification velocity of the molten pool. The solute enrichment behavior and severe micro-segregation of columnar crystal have great effect on the morphology and growth velocity of microstructure during the EBAM. The proposed phase field model can be used to reduce the internal structure defects and select the optimal process for the desired components of the EBAM with excellent microstructure and performance.

The general objective pursued in this research is to describe and predict the students’ reading habit, reading interest, reading motivation, and reading self-efficacy to their reading competency in the Senior High School. The design applied is a quantitative research. There were 124 students recruited using cluster sampling technique. Data were gathered using four rating scales and a reading test. The obtained data were analyzed in two phases, namely: descriptively and inferentially. Descriptively, central tendency measures and dispersion were computed for the four predictor variables and one criterion variable. Whereas inferentially, gross and net contributions of the four predictor variables to the criterion variables were computed using regression analysis technique.  Descriptively, the mean scores of reading habit, reading interest, reading motivation, reading self-efficacy, and reading comprehension are categorically moderate. The multiple correlation between the predictor variables and the criterion variable is highly significant (R= 78.7%). The contribution of the predictor variable to the criterion variable is as much as 61.9%. The research findings imply effective efforts to the betterment of reading habit, interest, motivation, self-efficacy as well as the the students’ reading comprehension in SMAN 1 Kuta Selatan.
