Women's Education: An Important Tool for Birth Reduction? A GMM - Poisson Regression Model Approach
Authors: Yedan Ali
Published: February 2020

Burkina Faso is a country with a shallow level of woman’s education. However, it is one of the most fertile countries. This paper analyzes whether the education of women reduces the number of births and the Total Fertility Rate in Burkina Faso. It also predicts the average number of births per woman and the Total Fertility Rate if women were better educated. Using data from the Demographic and Health Surveys, I model the two-stage Generalized Method of Moments (GMM) with the Heckman model and Poisson regression. The results show that the high fertility in Burkina Faso is mainly due to the low level of the woman’s education. The post-primary education increases the age at first birth. The number of births per woman would be decreased in the quarter and the Total Fertility Rate would pass from 5.4 to 3.6 if all women had at least completed the primary school. If all women had at least an incomplete secondary school, the number of births per woman would halve and the Total Fertility Rate would become 2.0. The government would do better to improve the education system allowing a good education for all, especially for women if it intends to reduce fertility.

Authors: Mejouar Asma , El Fatoiki Fatimzahra , Hali Fouzia , Chiheb Soumiya
Published: February 2020

Introduction: Infantile digital fibromatosis (FDI) is a rare, recurrent, benign tumor that occurs in the fingers and toes at birth or in the first months of life. We report a new case. Case report: A 2 1/2-year-old girl had light-pink, non-painful, hard, solid tumor formations, sitting on the dorsal surface of the fifth metatarsal bilaterally and the 2nd phalanx of the 5th left finger, resulting in joint deformity and then functional discomfort. X-rays of the front and the profile of the fingers showed a chondroma of P2 of the 5th finger, without anomaly on the X-ray of the knees. On the ultrasound of the soft parts: the presence of soft masses very hypoechogene avascular compared to the 5th ray measuring 2.81cm on the right and 1.21cm on the left. The diagnosis of infantile digital fibromatosis was retained. Surgical treatment was undertaken.Conclusion: The FDI is a rare and often easy diagnostic entity. Its recognition is important to consider adequate treatment knowing that this lesion can regress spontaneously and that post-surgical recurrence are frequent.
A Prelude to the Study of Indigenous, Pre-European, Church Architecture of Kerala
Authors: Sunil Edward
Published: February 2020

Christianity is believed to have been first introduced to Kerala in 52 CE through St. Thomas, the Apostle. This paper introduces the traditional indigenous Church architecture of Kerala that existed before the arrival of Portuguese in 1498 CE. The paper mainly looks into the circumstances under which it got destroyed and also analyses the reasons for its disappearance. The paper concludes that after the arrival of the Europeans and, in their initiative to bring the Kerala church closer to the Western church, they constituted a conscious attempt to alter the religious architecture of traditional Kerala Christians, declaring that it was Hindu by nature. Their intervention caused an irreparable break in the age-old system, and introduced a totally new and alien style to the traditional church building character, form and scale, forcing the traditional church architecture of centuries to be wiped off forever.

Authors: C. Hannah  , S. Tadepalli  , P. Gopalkrishnan
Published: February 2020

The practice of urban planning and building design largely follow traditional methods while transforming the structure and quality of life in the built environment. The process of managing cities requires updates and integration of new technologies and research efforts. In this context, development of smart, sustainable, energy efficient, healthy, safe and secure built environment is a priority that is shaping modern cities all over the world. Though management of Indian cities tries to address these issues to a certain extent, it can be said that, as compared to many developed countries, aspects of safety and security have not been the top priority of our planners and designers. Research on Environmental Criminology and Environmental Psychology clearly indicates the important role and benefits of crime prevention through appropriate design of the built environment. In this context, this paper highlights the role of crime prevention strategies and the relevance of environmental criminology in current building practices for addressing security concerns in India.

Istnienie problemów AI-zupełnych przyczyniło się do poszukiwań alternatywnych sposobów rozwiązywania problemów sztucznej inteligencji, nie opartych wyłącznie na pracy komputera. Pomimo że komunikacja jest dla ludzi czymś oczywistym, nadal nie istnieje sposób jej automatyzacji. Aktualnie powszechnie stosowanym podejściem w rozwiązywaniu problemów NLP jest podejście statystyczne, którego powodzenie zależy od wielkości korpusu językowego. Przygotowanie rzetelnego zbioru danych jest zatem kluczowym aspektem tworzenia statystycznego systemu sztucznej inteligencji. Z uwagi na zaangażowanie specjalistów jest to proces czasochłonny i kosztowny. Jednym z obiecujących podejść, pomagających zredukować czas i koszt tworzenia otagowanego korpusu, jest korzystanie z gier skierowanych na cel. Ambicją niniejszej pracy jest przybliżenie poszczególnych etapów tworzenia gry przeznaczonej do pozyskania zasobów językowych oraz omówienie skuteczności jej działania. Analiza ta zostanie przeprowadzona na podstawie kolekcji gier Wordrobe wspierających anotacje korpusu języka naturalnego.
Za młodzi, za biedni? Orientacja na małżeństwo młodych dorosłych niebędących w związku małżeńskim
Authors: Wieteska Magda
Published: February 2020

Młodzi Polacy coraz rzadziej wstępują w związki małżeńskie. W 2013 r. zawarto 180,4 tys. małżeństw – to o ponad 20 tys. mniej niż rok wcześniej. Wraz ze spadkiem liczby zawieranych związków małżeńskich wzrósł z kolei wiek osób, które decydują się na małżeństwo. Wśród powodów, dla których młodzi dorośli nie legalizują intymnych relacji, wymienia się upowszechnienie kultury indywidualizmu, brak gotowości emocjonalnej korelującej z przedłużaniem okresu moratorium psychospołecznego, a także deficyt zasobów finansowych stanowiących niezbędne podłoże dla założenia rodziny.

W artykule przedstawiam poglądy młodych dorosłych na instytucję małżeństwa oraz czynniki, które nie/motywują ich do zalegalizowania intymnej relacji.

Jesteśmy z wami, ludzie walczącej Korei. Obraz Korei Północnej w Polskiej Kronice Filmowej 1947 – 1984
Authors: Matusik Marta Maria
Published: February 2020

Zmiany ustrojowe w Polsce po zakończeniu drugiej wojny światowej przyniosły nie tylko przekształcenia dotychczasowej sytuacji wewnętrznej. Polska zyskała także nowych sojuszników, dobieranych wobec ideologicznego klucza. Interesująca wydaje się kwestia, w jaki sposób komunistyczna propaganda przedstawiała w oficjalnych przekazach nowych, pozaeuropejskich sojuszników, na temat których wiedza była z całą pewnością bardzo ograniczona. Szczególnie reprezentatywna dla tego grona jest Korea Północna, której – za sprawą toczącej się w latach 1950-1953 wojny koreańskiej – propaganda poświęcała szczególnie dużo uwagi, zwłaszcza w swoim podstawowym środku przekazu, jakim była funkcjonująca już od 1944 r. Polska Kronika Filmowa. Celem artykułu jest – poprzez analizę kronik poświęconych tematyce koreańskiej – pokazanie, w jaki sposób propaganda starała się tworzyć obraz nowego i nieznanego sojusznika, by uczynić go bliskim sprawy polskiej.

On Some Criminological Parameters of Ensuring Anti-Drug Security
Authors: Sudakova Tatyana , Vasilyeva Maria
Published: February 2020

The current state strategy of national security enumerates some crucial directions of its implementation. Illegal drug trade, when carried out by criminal organizations and groups in most dangerous forms, is identified by legislators as a separate problem among the threats to national security. Thus, the anti-drug security today acquires a specific meaning and significance within the context of determining its vital indicators and criteria of effectiveness to ensure the protection and sustainable development of society. The understanding of anti-drug security is connected with a complex of consolidated legal, political, information, socio-economic and other measures aimed at further development and implementation of the state policy of counteracting the activities of criminal organizations and groups connected with illegal drug trade with the goal of ensuring national interests and strategic national priorities. One of the criteria of the effectiveness of anti-drug security measures is the implementation of the policy of counteracting illegal drug trade and other forms of illegal trafficking carried out in a group. The official information on the effectiveness of such policy shows that there are no serious results in this sphere. These conclusions are based on the stable average statistical domination of persons convicted for illegal operations with drugs without the goal of selling (over 70 % of all persons convicted for drug crimes) among all those convicted for such operations. This indicator has been increasing year-on-year practically during the whole past decade. The specific weight of persons convicted for collective crimes has traditionally been insignificant in the structure of all illegal drug trade and does not exceed 8–9 % of all drug-related crime. These statistical facts are totally in discord with the priorities outlined in the policy of counteracting illegal drug trade. The causes of statistical dominance of such indicators are connected with the organizational and legal difficulties in the work of the law enforcement system, which is supported by the statistical and specific sociological methods used in the research of the regional specifics of these processes.
Waiver of the Right (Loss of the Right) to a Confrontation by Committing an Unlawful Act (Forfeiture by Wrongdoing)
Authors: Ghambaryan Artur
Published: February 2020

The article deals with a number of theoretical issues of the waiver, in particular, the concept and types of waiver of the right to a confrontation. The author shows the correlation between the concepts «waiver of the right» and «loss of the right» and points out that when a person commits an unlawful act, he waives the right to a confrontation and hinders the normal course of court hearings through the unlawful influence on trial participants, evasion from proceedings or unauthorized leaving of a courtroom. If the defendant impedes the natural progress of court hearings, he is warned about the possibility of being removed from the courtroom if the unlawful conduct does not stop. If he continues to commit unlawful acts during the court session, then he in fact waives his right to participate in the court hearing and the right to a confrontation (loses these rights). The author points out that in practice there are cases when the accused person evades the investigation and stays on the wanted list for years or when a person leaves for another country to evade the investigation and, as a result, is deprived of an opportunity to interrogate the witnesses who testified against him because these witnesses are no longer available, for example, they have died, or are in the country where the crime was committed. The author also considers the situations when the accused leaves the court hearing without authorization as a waiver of the right to confrontation. In this case the accused does not insist on his right and waives these constitutional privileges because he was given a right to confrontation but chose not to use it and not to meet the witnesses who have testified against him.
Improved tear film stability in patients with dry eye after hyaluronic acid and galactoxyloglucan use v1
Authors: Molina Solana Pedro
Published: February 2020

Purpose:Artificial tears only provide transient relief for dry eye. To the best of our knowledge, this is the first study to objectively compare treatment with artificial tears with Keratograph 5M, which allows accurate and objective investigation of dry eye and artificial tear treatment. We aimed to evaluate whether a preservative-free combination of 0.4% hyaluronic acid and 0.2% galactoxyloglucan can improve dry eye using the new topographer, Keratograph 5M. Patients and methods: This prospective longitudinal, single-arm interventional cohort study was performed at a tertiary referral center and involved 20 patients with dry eye (40 eyes). Preservative-free artificial tears were administered every 3 hours. The participants underwent clinical and instrumental evaluations at baseline and 1 week and 1 month after treatment. Baseline values were considered as the controls. All patients were assessed with Keratograph 5M for non-invasive Keratograph first break-up time and non-invasive Keratograph average break-up time, conjunctival hyperemia, and tear meniscus height. Ocular surface staining with fluorescein was evaluated using the slit-lamp and fluorescein break-up time examinations, and the ocular surface disease index score was recorded for each patient. Results:The signs and symptoms improved after 1 month of preservative-free 0.4% hyaluronic acid and 0.2% galactoxyloglucan treatment. There was a significant increase in the non-invasive Keratograph first break-up time and non-invasive Keratograph average break-up time at 15, 30, 60, and 90 min, and 1 week and 1 month (P < .05) and a decrease in hyperemia, corneal staining, and Ocular Surface Disease Index scores after 1 week and 1 month (P < .05). No treatment-related adverse event was observed. Conclusions: A combination of 0.4% hyaluronic acid 0.2% galactoxyloglucan artificial tears seems effective for treating dry eye. Keratograph 5M can objectively detect these changes during the follow-up period.
Practical evaluation of velocity effects on the magnetic flux leakage technique for storage tank inspection
Authors: Pullen A L , Charlton P C , Pearson N R , Whitehead N J
Published: February 2020

Magnetic flux leakage (MFL) is a technique commonly used to inspect storage tank floors. This paper describes a practical evaluation of the effect of scanning velocity on defect detection in mild steel plates with thicknesses of 6 mm, 12 mm and 16 mm using a fixed permanent magnetic
yoke. Each plate includes four semi-spherical defects ranging from 20% to 80% through-wall thickness. It was found that scanning velocity has a direct effect on defect characterisation due to the distorted magnetic field resulting from induced eddy currents that affect the MFL signal amplitude.
This occurs when the inspection velocity is increased and a reduction in the MFL signal amplitudes is observed for far-surface defects. The opposite applies for the top surface, where an increase is seen for near-surface MFL amplitudes when there is insufficient flux saturating the inspection
material due to the concentration of induced flux near the top surface. These findings suggest that procedures should be altered to minimise these effects based on inspection requirements. For thicker plates and when far-surface defects are of interest, inspection speeds should be reduced.
If only near-surface defects are being considered then increased speeds can be used, provided that the sensor range is sufficient to cope with the increased signal amplitudes so that signal clipping does not become an issue.
Defect size estimation method for magnetic flux leakage signals using convolutional neural networks
Authors: Wang Hong'an , Chen Guoming
Published: February 2020

A method for defect size estimation of magnetic flux leakage (MFL) signals using convolutional neural networks (CNNs) is proposed to overcome the problem of quantitative identification of pipeline MFL testing. The model mainly includes two modules: defect classification and defect size
regression. The former is used to realise data fusion, feature extraction and tasks of three components (axial, circumferential and radial) of the MFL defect signal. The defect size regression module includes seven CNNs, which realise the size estimation of different types of defect. The input
is a different type of defect in the defect classification module and the output is the length, width and depth information of the defect. Finally, the training and prediction are conducted using a defect dataset. The results show that the proposed method can effectively identify the MFL defect
size of the pipeline.

Published: February 2020

Background: In the management of head and neck cancer (HNC), assessment of quality of life (QoL) is imperative because of the potentially debilitating effect of treatment toxicities. Currently, there are no published data assessing the QoL in Filipino HNC patients, thus this study.

Methods: This cross-sectional study utilized the University of the Philippines - Department of Health Quality of Life scale. Patients with head and neck cancers at the University of the Philippines - Philippine General Hospital from February to September 2019 were invited to participate.  

Results: A total of 418 patients were included in the study with a mean age of 42 years old (range 18 to 73 years old). In general, Filipino head and neck cancer patients had moderate QoL (mean score of 4.59±0.79). All of the QoL domains (physical, emotional, cognitive, and related functions) had a score of 3-5 (moderate), except for the social status domain which had a mean score of 5.51±0.83 (high). Among socio-demographic factors, patients who are employed and with additional funding sources on top of their income have better global QoL (p<0.01). Clinically, patients with higher stages of disease, fungating tumors, post-laryngectomy, have a feeding tube, with a tracheostomy, and had chemotherapy have lower global QoL (p<0.01).

Conclusions: Filipino patients with head and neck cancers have an overall moderate quality of life, with high scores in the social domain. Patients with higher tumor burdens and have been exposed to chemotherapy have lower QoL scores, while patients with financial stability and aid have better QoL scores.

Published: February 2020

Employee turnover is a current challenge of human resource management in organizations. Staff turnover is regarded as a key performance indicator for Human Resources departments, and a serious rise in its level points to events, issues or problems which may severely hamper the successful and efficient operation of any organization. Hence, in such cases immediate measures should be taken to curtail turnover. The paper reviews briefly current trends of labor market and specific HRM challenges of public services. In this study an empirical research is also introduced. Employees with adequate professional experience represent outstanding value for operational efficiency, a turnover index compiled by on a sectoral basis, highlights the fact that turnover is highest among blue collar workers in the private sector. Surprisingly, within the same group in the public sector turnover is typically low. At the same time, however, our 2017 results show that astonishingly high levels of turnover (even 40%) may also occur in public sector organizations. Public sector in Hungary has provided life long employment but the new labor regulation and labor shortages have drastic changed the particular traits.

Four of which are the endemic species of Lesser Sunda Islands, namely Oreophryne monticola, Limnonectes kadarsani, Limnonectes dammermani dan Hylarana florensis. However, the information regarding the habitat characteristic which supports animal survival is limited. This study aimed to explore the types of habitat characteristics according to amphibian diversity in the Island of Lombok. The survey study was conducted at 9 locations (3 of habitat type) from March to July 2016. The collected data includes species composition and a sum of individuals of species. Amphibian diversity was analyzed using relative abundance and the Shannon-Wiener index. This study revealed that the nonforest habitat type was appropriate for five species, while secondary and primary forest habitat type was appropriate for seven species. Diversity of species index directly proportional to a natural level of habitat (H’ Nonforest = 1.3; H’ Secondary Forest = 1.7; H’ Primary Forest = 1.8). The highest species abundance was Bufo melanostictus (23.9%), and the lowest species abundance was Oreophryne monticola (0.9%). According to the distribution and relative abundance, the species that require conservation priorities are Oreophryne monticola and Hylarana florensis.

Korosi merupakan masalah besar bagi bangunan dan peralatan yang menggunakan material dasar logam. Beberapa cara yang dapat memperlambat laju reaksi korosi antara lain, dengan cara penambahan zat (inhibitor). Bahan alam dapat digunakan sebagai inhibitor organik, seperti biji kopi dan daun teh. Metode pengukuran korosi yang digunakan dalam penelitian ini adalah metode kehilangan berat (gravimetri). Dengan penambahan inhibitor biji kopi dan daun teh, mampu menghambat laju korosi pada logam seng dalam larutan HCl. Koefisien korelasi linear yang didapatkan untuk masing-masing inhibitor alami adalah untuk inhibitor biji kopi adalah 0,661 dan koefisien korelasi linear untuk inhibitor daun teh adalah 0,6392, berdasarkan teori Adsorpsi Isoterm Langmuir. Dari persamaan linear pada logam seng  diperoleh nilai regresi tanpa inhibitor yaitu 0,9579, regresi dengan penambahan inhibitor biji kopi yaitu 0,77 dan regresi dengan penambahan inhibitor daun teh yaitu 0,7547

Pestisida merupakan racun yang sengaja dibuat oleh manusia untuk membunuh organisme pengganggu tanaman dan insekta penyebar penyakit. Organofosfat merupakan jenis pestisida yang paling banyak di gunakan di bidang pertanian. Paparan pestisida yang terlalu sering dapat menimbulkan berbagai masalah kesehatan. Biomarker yang paling sering dipakai dalam menentukan gejala keracunan pestisida adalah kadar kolinesterase. Oleh karena itu pada penelitian ini akan diteliti pengaruh lama paparan pestisida terhadap kolinesterase (ChE) dan transaminase (SGOT dan SGPT). Pemeriksaan kolinesterase dilakukan dengan menggunakan metode spektrofotometri menggunakan reagen thiol 5,5'-dithio-bis (2-nitro asam benzoat) (DTNB), sedangkan pemeriksaan SGOT dan SGPT dilakukan menggunakan photometer. Hasil menunjukkan bahwa tidak ada pengaruh antara lama paparan pestisida organofosfat dengan kadar SGOT, SGPT, dan kolinesterase. Hal ini disebabkan karena seluruh responden tertib dalam pemakaian APD selama bekerja.

Published: February 2020

Background : Care pathways (CPWs) are complex interventions that have the potential to reduce treatment errors and optimize patient outcomes by translating evidence into local practice. To design an optimal implementation strategy, potential barriers to and facilitators of implementation must be considered. The objective of this systematic review is to identify barriers to and facilitators of the implementation of CPWs in primary care (PC). Methods : A systematic search via Cochrane Library, CINAHL, and MEDLINE via PubMed supplemented by hand searches and citation tracing was carried out. We considered articles reporting on CPWs targeting patients at least 65 years of age in outpatient settings that were written in the English or German language and were published between 2007 and 2019. We considered (non-)randomized controlled trials, controlled before-after studies, interrupted time series studies ( main project reports ) as well as associated process evaluation reports of either methodology. Two independent researchers performed the study selection; the data extraction and critical appraisal were duplicated until the point of perfect agreement between the two reviewers. Due to the heterogeneity of the included studies, a narrative synthesis was performed. Results : 14 studies (seven main project reports and seven process evaluation reports) of the identified 8,154 records in the search update were included in the synthesis. The structure and content of the interventions as well as the quality of evidence of the studies varied. The identified barriers and facilitators were classified using the Context and Implementation of Complex Interventions framework . The identified barriers were inadequate staffing, insufficient education, lack of financial compensation, low motivation and lack of time. Adequate skills and knowledge through training activities for health professionals, good interprofessional communication and individual tailored interventions were identified as facilitators. Conclusions : In the implementation of CPWs in PC, a multitude of barriers and facilitators must be considered, and most of them can be modified through the careful design of intervention and implementation strategies. Furthermore, process evaluations must become a standard component of implementing CPWs to enable other projects to build upon previous experience.

Plant calmodulin-binding transcription activator (CAMTA) proteins play important roles in hormone signal transduction, developmental regulation, and environmental stress tolerance. However, in wheat, the CAMTA gene family has not been systematically characterized. In this work, 15 wheat CAMTA genes were identified using a genome-wide search method. Their chromosome location, physicochemical properties, subcellular localization, gene structure, protein domain, and promoter cis-elements were systematically analyzed. Phylogenetic analysis classified the TaCAMTA genes into three groups (groups A, B, and C), numbered 7, 6, and 2, respectively. The results showed that most TaCAMTA genes contained stress-related cis-elements. Finally, to obtain tissue-specific and stress-responsive candidates, the expression profiles of the TaCAMTAs in various tissues and under biotic and abiotic stresses were investigated. Tissue-specific expression analysis showed that all of the TaCAMTA genes were expressed in multiple tissues, suggesting that the wheat CAMTA genes may play important roles in growth and development. Under abiotic stress, TaCAMTA1, 3, and 6 were up-regulated after drought treatment, while the expression levels of TaCAMTA1 and 3 were induced after cold treatment, indicating that they may be involved in drought and cold stress response. This work systematically identified the CAMTA gene family in wheat at the whole-genome-wide level, providing important candidates for further functional analysis in developmental regulation and the stress response in wheat.

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype defined by lack of hormone receptor expression and non-amplified HER2. Adavosertib (AZD1775) is a potent, small molecule, ATP-competitive inhibitor of the Wee1 kinase that potentiates the activity of many DNA-damaging chemotherapeutics and is currently in clinical development for multiple indications. The purpose of this study was to investigate the combination of AZD1775 and capecitabine/5-FU in preclinical TNBC models. Methods: TNBC cell lines were treated with AZD1775 and 5-FU and cellular proliferation was assessed in real-time using IncuCyte® Live Cell Analysis. Apoptosis was assessed via the Caspase-Glo 3/7 assay system. Western blotting was used to assess changes in expression of downstream effectors. TNBC PDX models were treated with AZD1775, capecitabine, or the combination and assessed for tumor growth inhibition. Results: From the initial PDX screen, two of the four TNBC PDX models demonstrated a better response in the combination treatment than either of the single agents. As confirmation, two PDX models were expanded for statistical comparison . Both PDX models demonstrated a significant growth inhibition in the combination versus either of the single agents. (TNBC012, p<0.05 combo vs adavosertib or capecitabine, TNBC013, p<0.01 combo vs adavosertib or capecitabine ). An enhanced antiproliferative effect was observed in the adavosertib/5-FU combination treatment as measured by live cell analysis. An increase in apoptosis was observed in two of the four cell lines in the combination when compared to single agent treatment. Treatment with single agent adavosertib resulted in an increase in p-CDC2 in a dose dependent manner that was also observed in the combination treatment. Similar results were observed with γH2AX in two of the four cell lines tested. No significant changes were observed in Bcl-xL following treatment in any of the cell lines. Conclusions: The combination of adavosertib and capecitabine/5-FU demonstrated enhanced combination effects both in vitro and in vivo in preclinical models of TNBC. These results support the clinical investigation of this combination in patients with TNBC, including those with brain metastasis given the CNS penetration of both agents.
