Published: June 2019

Abstract: The Hellenic Library Union Catalog (HLUC) is one of the projects that were developed as a result of the relocation of the National Library of Greece (NLG), as a part of Action 2 "Development of Digital Services" and was fully funded by the Stavros Niarchos Foundation. It is an information system that aims to integrate and highlight all the collections from the Greek libraries in one single catalog. It was designed and implemented by the NTUA Annex of the Hellenic Academic Libraries Link, in collaboration with the National Library of Greece. It essentially organizes an open access collection of high- quality bibliographic data and aims to promote, amongst other things, rare, special and other types of bibliographic material. All Greek libraries are invited to participate.Currently HLUC is in a pilot phase. So far, more than 50 libraries from Greece and Cyprus are participating and the number of participants is increasing. The objective of the pilot phase was to test the operation of the HLUC by controlling the entire workflow starting from the moment that the data is imported to the system, incorporated and presented via the HLUC environment. Also system failures will be identified and corrected and functions as well as the general infrastructure will be improved. During this pilot phase, system reports will be sent to the member libraries aiming to receive their feedback, in order to improve the services provided by the HLUC. The purpose of this paper is to describe all the procedures followed for studying, designing and developing the system and to present how it works.

Published: June 2019

The purpose of this study was to determine the effect of depression on mathematical problem solving abilities. This research is a qualitative research with a cross-sectional approach. This study involved 30 subjects from students of the Department of Mathematics Education, FKIP Universitas Islam Malang. The sampling technique used was convenience sampling. The data were collected through a questionnaire from the Beck Depression Inventory II (BDI-II) consisting of 21 questions. The process of solving mathematical problems is seen from the answer of the subject when working on mathematical questions based on Polya's problem solving steps. The results showed that subjects with normal levels of depression tended to have complete and sequential characteristics of mathematical solutions . Meanwhile, subjects with mild levels of depression tend to solve problems sequentially but incomplete. In addition, subjects with moderate levels of depression tended to solve mathematical problems in an irregular and incomplete manner. Further research is still required to examine the same issue by involving more research samples.الاكتئاب مشكلة في الصحة العقلية. كان الغرض من هذه الدراسة هو تحديد تأثير الاكتئاب على قدرات حل المشكلات الرياضية. هذا البحث هو بحث نوعي مع نهج مستعرض. شملت الدراسة 30 مادة من طلاب قسم تعليم الرياضيات، FKIP Universitas Islam Malang. كانت تقنية أخذ العينات المستخدمة هي أخذ العينات الملائمة. تتألف تقنية جمع البيانات المستخدمة في هذه الدراسة باستخدام استبيان من Beck Depression Inventory II (BDI-II) من 21 سؤالًا. يُنظر إلى عملية حل المشكلات الرياضية من إجابة الموضوع عند العمل على حل المشكلات الرياضية استنادًا إلى خطوات حل مشكلة Polya. أظهرت النتائج أن الأشخاص الذين يعانون من مستويات طبيعية من الاكتئاب يميلون إلى أن يكون لديهم خاصية كاملة ومتسلسلة للمشاكل الرياضية. وفي الوقت نفسه، تميل الأشخاص الذين يعانون من مستويات خفيفة من الاكتئاب إلى حل المشاكل في التسلسل ولكن غير مكتملة. علاوة على ذلك، يميل الأشخاص ذوو المستويات المعتدلة من الاكتئاب إلى حل المشكلات الرياضية بطريقة غير منتظمة وغير مكتملة. البحث اللاحق يجعل من الممكن فحص نفس الشيء الذي يتضمن المزيد من عينات البحث.
Parental Curse as Invisible Violence: Тhe Discourse of Anti-Maternity in the Traditional Culture of the XIX Century
Authors: Radulović Lidija 
Published: June 2019

Curse is an appellative genre, a clichéd verbal proverb that is uttered in belief, that with the assistance of supernatural forces, God or demon, through the magical properties of words, evil will come upon an individual. It is ex­amined through the context of the ideal motherhood discourse in the tradition culture of the XIX and the first half of the XX century, in view that it was perceived to be an idiosyncrasy of female demeanor. Maternity as a cultural construct in the traditional culture of Serbia is based upon the ideal mother­hood discourses as a gift from god, as an innate role for women, an inherent instinct for caring towards others, as an unconditional motherly love. In prac­tice, normative regulations and the concrete actions of a mother are not in complete concurrence, mothers love is not an objective fact, it can be present or not, vary in intensity, it can be selective, but it will depend on the personal history and cultural construct. Through such a focal point, motherly curse is perceived as a form of behavior that can be signified as anti-maternity. In the conceptualization of a parental curse, from one viewpoint, the manner of usual behavior of women that has no real implications on the life of the child is legitimized, and on the other hand, it is believed that a mothers curse has the most potent magical effect and is delivered up to the ninth generation. Parental curse and the ritual of “cursing” do not include a black magic con­notation, and were considered a legitimate social mechanism through which evil was countered with evil i.e. the transgressor was being punished in cases where there existed no formal mechanism of punishment. Through such ac­tions, the community, or family are re-imposing order in the social relations, synchronously sending a message that reaffirms the correct matrix of behavior and moral values of the community.
Automatic calibration and selection of optimal performance criterion of a water quality model for a river controlled by total maximum daily load (TMDL)
Authors: Cho Jae Heon , Lee Jong Ho 
Published: June 2019

Abstract
When manually calibrating water quality models, considerable time and attention are required. Hence, developing an automated model that allows for efficient and objective automatic calibration is highly desirable. The QUAL2Kw model calibrates the QUAL2K automatically using a genetic algorithm (GA). This study analyzes auto-calibration results and selects the optimal criterion for each objective function from six performance criteria. Additionally, a multi-objective auto-calibration was conducted using two kinds of performance statistics as the objective function of the GA. The auto-calibration model was applied to the Yeongsan River and the total maximum daily load (TMDL) was established to achieve water quality goals at specific target points of this river. Among the six auto-calibration results based on a single performance criterion, Nash-Sutcliffe model efficiency (NSE) was the best criterion for calculating fitness through auto-calibration. To consider the calibration accuracies of the TMDL target points and the entire river simultaneously, an objective function using multiple performance criteria, specifically the weighted average of the normalized root mean squares error (CV(RMSE)) and the ratio of the RMSE to the standard deviation of the observed data (the RSR), was selected as the final auto-calibration of the model. The model calibration performance was good across the whole region as well as at the target points.

Background:In continuation of our work on Mannich reaction on 8-hydroxyquinoline, fifteen different combinations of aromatic aldehydes and aniline were subjected to Mannich reaction from which twelve products (eight Mannich bases, two imines and two intramolecularly cyclized products with benzofuranone skeleton) were obtained. Among them six compounds (1, 2, 6, 8, 9 and 12) are the new compounds. The structures of the compounds were characterized by UV, IR, MS and 1H NMR.Method:The compounds were tested for the inhibition of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and Interleukin-1β (IL-1β) at a concentration of 25 µg/mL. The cytokines were produced by THP-1 cells differentiated with PMA for 24hrs and stimulated with LPS for 4 hrs and supernatant were analyzed through ELISA technique.Results and Discussion:Compounds 1-5, 8 and 9 inhibited the production of TNF-α and IL-1β. Compounds 1, 3, and 8 exerted potent inhibitions of TNF-α with 71%, 71%, and 83% inhibition, respectively. Compounds 1 and 8 significantly inhibited the production of IL-1β with 64% and 78% inhibition, respectively.Conclusion:Compounds 1 and 8 significantly inhibited the production of IL-1β with 64% and 78% inhibition, respectively. Notably compound 8 showed the most potent inhibition of these cytokines. Additionally, the effect of compounds on viability of THP-1 cells was also evaluated. Moreover, molecular docking was carried out to study the mechanism of inhibition of TNF-α production.

Background:Effective screening of colorectal cancer (CRC) in early stage could reduce the advancement of CRC and therefore mortality. Effective screening is based on either stool dependent tests or colon dependent examination.Aim:The aim of the study was a comparative evaluation of chromocolonoscopy and Colon Cancer-Specific Antigen-2 test for early detection of colorectal cancer in Egyptian patients.Methods:This case control study was carried out on 55 patients classified into 3 groups: Group I consisted of twenty patients with precancerous lesions detected by colonoscopy, Group II consisted of twenty patients diagnosed with colorectal cancer and Group III consisted of fifteen individuals (who underwent colonoscopy for other indications) as a control group. All the subjects were subjected to measure occult blood in the stool, measurement of Colon Cancer-Specific Antigen-2 level in serum and tissue and chromo colonoscopy using Indigo Carmine stain.Results:In group II, there was a statistically significant increase in CCSA2 in serum as compared to the other 2 groups. Cutoff >11.3 CCSA2 in serum showed 65% sensitivity, 85% specificity, 81.2% PPV, 70.8% NPV and 70.3% accuracy in the differentiation of group II with cancer colon from group I with premalignant colonic lesions. A cutoff > 9.1 CCSA2 in serum showed 95% sensitivity, 46.67% specificity, 70.4% PPV, 87.5% NPV and 73.5% accuracy in differentiating group II with cancer colon from normal controls (group III).Conclusion:CCSA-2 level in serum was significantly higher in cancer colon. Chromoendoscopy has a role in the detection of polyps, both neoplastic and non-neoplastic.

Understanding the globally harmonized system of classification and Labeling of Chemicals-The Purple Book
Authors: Rao Bayya Subba 
Published: June 2019

Global Harmonized System (GHS), relating to hazard chemicals, is a process of making a regulation among countries uniform to the extent possible so as to benefit an industry to export its products to several countries with one communication system. On one side, the system is helpful to develop communication as labeling and material safety data sheets, and on the other side is helpful for the personnel in the chemical and pharmaceutical industry in using chemicals carefully, especially hazardous. Such international guidelines are believed to be the most reliable information so that the end user of hazard chemicals is confident enough in handling and using. The current article is a brief understanding of the guideline, an attempt, how the hazard chemicals are being classified, communicated as labels, symbols and material safety data sheets.

Abstract
In this work is presented a pedagogical point of view of multifractal analysis deoxyribonucleic acid (DNA) sequences is presented. The DNA sequences are formed by 4 nucleotides (adenine, cytosine, guanine, and tymine). Following Jeffrey’s paper we associated a simple contractive function to each nucleotide, and constructed the Hutchinson’s operator W, which was used to build covers of different sizes of the unitary square Q, thus Wk
(Q) is a cover of Q, conformed by 4
k
squares Qk
of size 2

. Besides, it is obtained the optimal cover Ck
to the fractal F generated for each DNA sequence was obtained. We made a multifractal decomposition of Ck
in terms of the sets Jα
conformed by the Qk
’s with the same value of the Holder exponent α, and determined f (α), the Hausdorff dimension of Jα
, using the curdling theorem.

Published: June 2019

O objetivo do presente trabalho foi avaliar o potencial das imagens de radar do satélite Sentinel 1A (banda C) para discriminar classes representativas de uso e cobertura da terra do Distrito Federal, Brasil. As imagens de coerência interferométrica utilizadas nesse estudo foram obtidas a partir de pares de imagens Single Look Complex (SLC) de junho e julho de 2018. Foi gerada uma composição colorida RGB a partir de imagens de coerência, intensidade de retroespalhamento e razão de retroespalhamento. Essa imagen foi classificada pelos métodos supervisionados Support Vector Machine (SVM) e Random Forest (RF). A validação temática foi realizada por matrizes de confusão, índice Kappa e exatidão global. Nesse contexto, foram investigadas cinco classes temáticas (água, área urbana, vegetação nativa, pastagem e agricultura). O classificador RF obteve melhor desempenho classificatório (Kappa= 0,68 e exatidão global = 79,1%) que o classificador SVM (Kappa= 0,64 e exatidão global = 75,7%). A coerência mostrou-se eficiente principalmente na identificação de corpos d’água e da área urbana. Os resultados foram satisfatórios para a classificação de uso e cobertura da terra do Distrito Federal, no entanto, houve confusão entre algumas classes e erros de comissão na classe área urbana em ambas as classificações.
