As Origens do Mal em Agostinho/Les origines du Mal chez Augustin
Authors: Erculino Siloe Cristina do Nascimento 
Published: November 2019

Valendo-se de O Livre Arbítrio e As Confissões como principais referências, este estudo visa analisar a problematização que Agostinho faz do Mal, vez que o Bispo de Hipona refletiu sobre a possibilidade de conciliar o pilar cristão de infinita bondade divina com a existência do mal no real. Neste artigo separamos duas fases dessa reflexão. A primeira busca resolver o problema do mal como existente no universo físico, desenvolvendo para tanto uma ontologia que culmina na impossibilidade da existência do mal como substância: o Mal é privação do Bem. Já que o Mal não é substância, mas sim privação do Bem, não existe o mal natural: o mal genuíno é resultado da ação humana. Na segunda fase, o debate se dirige para o sujeito e o livre-arbítrio, ou seja, o âmbito moral. É preciso explicar por quais razões Deus nos deu o livre-arbítrio se com ele praticamos o mal. Como veremos, a possibilidade de escolher é um bem dado por Deus que permite a qualificação moral do ato, dessa forma, o homem deve possuir o livre-arbítrio para que possa ser justo ou injusto. Por fim, concluímos mostrando que as origens do mal estão na defecção da vontade que se afasta de Deus. Résumé : Nous analysons ici le problème du mal chez Augustin, en utilisant comme références principales les œuvres Le Libre Arbitre et Les Confessions. L'évêque d'Hippone a réfléchit sur la possibilité de concilier le pilier chrétien de la bonté infinie de Dieu avec l'existence du mal dans le réel. Nous avons séparé dans cet article deux phases de cette réflexion. La première vise à résoudre le problème du mal comme existant dans l'univers physique. Elle développe une ontologie qui culmine dans l'impossibilité de l'existence du mal en tant que substance: le mal est une privation du bien. Puisque le mal n'est pas une substance, mais bien il s’agit d’une privation du bien, il n’y a pas du mal naturel: le mal véritable est le résultat de l'action humaine. Dans la deuxième phase, le débat se dirige vers le sujet et le libre arbitre, en d'autres termes, le domaine de la morale. Il faut expliquer pourquoi Dieu nous a donné le libre arbitre alors que nous faisons du mal. Comme nous le verrons, la capacité de choisir est un Bien donné par Dieu qui permet à l'action morale, ainsi, l'homme doit avoir le libre arbitre afin qu'il puisse être juste ou injuste. On conclut en montrant que les origines du mal se trouvent dans la défection de la volonté qui se détourne de Dieu. Mots-clés : Augustin. Mal. Libre arbitre. Dieu.
Aristóteles e o problema da responsabilidade moral: predeterminismo ou indeterminismo?/Aristotle and the Problem of Moral Responsibility: Pre-determinism or Indeterminism?
Authors: Andreazza Tiaraju Molina 
Published: November 2019

Quando discute os atos voluntários, em EN III 1-5, Aristóteles aborda duas questões: (i) sob que condições alguém pode ser moralmente responsabilizado por suas ações e (ii) quando alguém pode ser dito livre para executar suas ações. Aristóteles defende que podemos ser moralmente responsabilizado apenas se está em nosso poder agir e também não agir. O objetivo deste ensaio é analisar (i) e (ii), investigando se a noção “está em seu poder” é utilizada em um sentido indeterminista ou predeterminista por Aristóteles. Será defendido que há referências textuais para ambas as leituras, o que torna a questão insolúvel. Abstract: When discusses the voluntary acts, in EN III 1-5, Aristotle deals with two questions: (i) under which conditions someone can be morally responsible for his actions and (ii) when someone can be seen as free to act. Aristotle argues that we can be morally responsible only if is in our power to act and also it is in our power not to act. The aim of this essay is to analyze (i) and (ii), considering if the concept of “in our power” is used by Aristotle in an indeterminist or pre-determinist sense. It will be defended that there are textual references in favor of both interpretations, from which we can conclude that the question is unsolvable. Key words: Indeterminism. Predeterminism. Voluntary.

Objective: Female sex workers (FSWs) under 20 years of age range from 1,000 to 575,000 in different cities and countries across the globe. There is only a handful of information on the reproductive health (RH) issues of these younger FSWs in the perspective of service utilization and healthcare system. We reviewed existing literature with a view to describe the reproductive health problems, service utilization, and service availability as well as information sources among the FSWs ages <20 years.
Materials and methods: A web-based search using Google, Google Scholar, MEDLINE/ PubMed/ PubMed Central, HINARI and JSTOR was performed in English Language. The prevalence of a health issue and percentage of service utilization had been shown using ranges of minimum and maximum value which were calculated by different studies.
Results: Findings identified the following RH problems: unintended pregnancies (52% - 95%), induced abortion (51% - 53%), repeated or multiple abortions (13% - 43%), childbirth experiences, sexually transmitted infections (74%-84%), HIV (1% - 60.6%), violence (beaten, robbed, not paid, forced or coerced sex, rape) and mental disorders (depression, suicidal thoughts). The consistent use of condom (26%-55%) was not satisfactory. Overall 64% of under 20 years FSWs reported little or no access to healthcare in the previous year and access to RH information sources was also poor.
Conclusion: This review has potentially meant to bring forward the RH issues of younger FSWs to the policy makers and programme planners to implement targeted reproductive health interventions for the FSWs ages <20 years.

Published: November 2019

Background: Birth defect is one of the most important causes of neonatal mortality worldwide. In a developing country like Bangladesh many possible factors for birth defects are present which should be identified. This study was performed to determine those risk factors of birth defect and complications associated with it.
Materials and Methods: A hospital based matched case-control study was conducted from August 2015 to July 2016 in department of Neonatology along with Obstetrics and Gynecology at BSMMU. A total of 98 mother-infant pair (49 babies with birth defect as cases and 49 healthy babies without any birth defects as controls) was included in the study. For each case, a gestational age, sex and post-natal age matched control was taken. Data was collected by face to face interview. Univariate and multivariate conditional logistic regression models were computed to examine the effect of independent variables on outcome variable using SPSS 23.0. Variables with p-value <0.05 were considered statistically significant.
Results: The mean (± SD) birth weight for cases and controls were 2718.37 (±756.9) grams, and 2617.14 (±978.8) grams respectively. Cardiovascular system was the predominant system (21%) involved in birth defects. Maternal age between 20-29 years (AOR: 4.69; 95% CI 1.078, 20.448), less than four antenatal care visits (AOR: 10.07; 95% CI 2.816, 36.0), no multivitamin intake (AOR: 7.38; 95% CI 1.791, 30.365) and presence of maternal diabetes (AOR: 0.194; 95% CI 0.047, 0.799) were significantly associated with birth defects among newborns. Sepsis, asphyxia, hypoglycemia and dyselectrolytemia were the most prevalent problems among these babies. The need of intravenous fluid, thermal care, antibiotics and mechanical ventilation was also high among the cases.
Conclusion: Birth defect is an upcoming issue in current newborn health situation which need to be prioritized. Significant risk factors should be addressed timely for early diagnosis and proper management of these babies can help in reduction of mortality.

Published: November 2019

Pengolahan air limbah merupakan proses mengolah air buangan yang sudah tidak terpakai untuk dapat dikembalikan ke siklus air di lingkungan. Unit Waste Water Treatment Plant (WWTP) PT. Indonesia Power digunakan untuk mengolah air limbah yang berasal dari berbagai sumber salah satunya yaitu HRSG Sump Pit. Buangan air limbah yang berasal dari HRSG Sump Pit memiliki kandungan fosfat dikarenakan adanya penambahan fosfat pada unit sebelumnya yang bertujuan sebagai inhibitor proses korosi. Karakteristik limbah cair dapat ditentukan dari beberapa parameter diantaranya nilai pH, optical density (OD), dan kadar fosfat. Pengolahan air limbah dilakukan agar limbah cair yang dihasilkan dapat memenuhi baku mutu yang dipersyaratkan sebelum dibuang ke lingkungan. Penelitian ini dilakukan dengan mengaplikasikan reaksi fotokatalisis berbasis katalis TiO2/karbon aktif pada berbagai komposisi katalis dan durasi penyinaran. Proses fotokatalisis dilakukan dengan penambahan katalis pada perbandingan komposisi TiO2/karbon aktif 10:1, 5:1, 3:1 dan 2:1. Sedangkan lama waktu penyinaran 3, 4, 5, dan 6 jam. Hasil penelitian menunjukkan bahwa pH terendah sesuai baku mutu yaitu 8,13 dan penurunan kadar fosfat sebesar 70,12% mampu dicapai pada komposisi katalis TiO2/karbon aktif 3:1 dengan durasi penyinaran 5 jam. Penurunan OD tertinggi dicapai pada kondisi perbandingan komposisi katalis TiO2/karbon aktif 10:1 dan durasi penyinaran 6 jam yaitu sebesar 98,86%.

Water treatment is the process of treating water discharges that are not used to be discarded into the environment. Wastewater Treatment Unit Plant (WWTP) of PT. Indonesia Power is used to treat wastewater coming from several sources, one of which is HRSG Sump Pit. Wastewater from the HRSG Pit contains phosphate which is related to the phosphate addition in the previous unit which is needed as an inhibitor of corrosion process. The characteristics of liquid waste can be determined from several parameters such as pH value, optical density (OD), and phosphate content. Wastewater treatment is carried out to obtain liquid waste which comply to the quality standards before being discarded into the environment. This research was carried out by applying the photocatalysis reaction based on catalyst TiO2-activated carbon with various catalyst compositions and irradiation duration. The process of photocatalysis was carried out by adding catalysts to the ratio of the composition of TiO2 / activated carbon 10:1, 5:1, 3:1 and 2:1. While the irradiation time is 3, 4, 5 and 6 hours. The results show that the lowest pH according to quality standards was 8.13 and a reduction in phosphate content of 70.12% was achieved in the 3: 1 TiO2/activated carbon catalyst composition with a 5-hour irradiation duration. The highest OD reduction was achieved under the condition ratio of catalyst composition of TiO2/activated carbon 10:1 and the irradiation duration of 6 hours that was equal to 98.86%.
Effect of C Addition on as-Cast Microstructures of High Nb Containing TiAl Alloys

Published: November 2019

Two high Nb-containing TiAl alloys, Ti46.6Al7.5Nb0.5Si0.2B (Alloy A) and Ti46.1Al7.4Nb5C0.5Si0.2B (Alloy B), were prepared by graphite mold casting. As-cast microstructures of the two alloys were characterized to clarify the effect of carbon addition. The results show that 5 at.% carbon addition can change the primary solidification phase from β phase to α phase. The as-cast microstructure of Alloy A consists of a fully α2 + γ lamellar structure and interdendritic eutectic silicide with a volume fraction of 2.3%. However, in Alloy B, the lamellar structure only forms in the dendritic stem and the massive γ is observed in the interdendritic regions. Two types of carbides, Ti 2 AlC and TiC, are produced in Alloy B. A large number of randomly distributed primary Ti 2 AlC particles with volume fraction of 14.9% are observed in both the dendritic and interdendritic regions. Irregularly shaped TiC remains inside of the large Ti 2 AlC particle, suggesting TiC carbides transformed to Ti 2 AlC during cooling. The addition of carbon also changes the morphology of the silicides from a eutectic structure to a blocky structure in the massive γ matrix or at the interface of the Ti2AlC and the γ matrix. High level of niobium greatly increases the solid solution limit of carbon, since C content in the matrix is much higher than the solid solubility of that in the TiAl binary system. The hardness of the matrix increases from 325 HV to 917 HV caused by the addition of carbon.
