We present a detailed study of emission-line systems in the Galaxy And Mass Assembly (GAMA) G23 region, making use of Wide-field Infrared Survey Explorer (WISE) photometry that includes carefully measured resolved sources. After applying several cuts to the initial catalog of ∼41,000 galaxies, we extract a sample of 9809 galaxies. We then compare the spectral diagnostic Baldwin, Philips & Terlevich (BPT) classification of 1154 emission-line galaxies (38% resolved in W1) to their location in the WISE color–color diagram, leading to the creation of a new zone for mid-infrared “warm” galaxies located 2σ above the star-forming sequence, below the standard WISE active galactic nucleus (AGN) region. We find that the BPT and WISE diagrams agree on the classification for 85% and 8% of the galaxies as non-AGN (star-forming = SF) and AGN, respectively, and disagree on ∼7% of the entire classified sample. Thirty-nine percent of the AGNs (all types) are broad-line systems for which the [N ii] and [Hα] fluxes can barely be disentangled, giving in most cases spurious [N ii]/[Hα] flux ratios. However, several optical AGNs appear to be completely consistent with SF in WISE. We argue that these could be low-power AGNs, or systems whose hosts dominate the IR emission. Alternatively, given the sometimes high [O iii] luminosity in these galaxies, the emission lines may be generated by shocks coming from super-winds associated with SF rather than AGN activity. Based on our findings, we have created a new diagnostic: [W1 – W2] versus [N ii]/[Hα], which has the virtue of separating SF from AGNs and high-excitation sources. It classifies 3 to ∼5 times more galaxies than the classic BPT.
Space Weathering Affects the Remote Near-IR Identification of Phyllosilicates

Published: November 2020

Near-infrared (NIR) spectrometers on board current sample return missions Hayabusa2 and the Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) from primitive bodies detected the presence of hydrated silicates on the surface of asteroids Ryugu and Bennu, respectively. These detections relied upon the study of the 2.7 μm OH-stretching spectral feature, whose peak position is related to the composition and structure of minerals. However, space weathering might alter the band profile, depth and position, thus complicating the interpretation of remote sensing data. In order to better understand these processes and provide support to space missions, we performed ion bombardment experiments on serpentine and saponite analogs. These two phyllosilicates are among the dominant mineral phases found in hydrated carbonaceous chondrites, which are possible analogs to surface materials observed on these primitive asteroids. We studied the behavior of the 2.7 μm band as a function of ion fluence and found that the evolution of the phyllosilicate depends on its nature. For the saponite sample, the band is only slightly affected by ion bombardment, while for both serpentine samples it shifts toward longer wavelengths. For both samples, peak intensity and width is not strongly affected. The band shift for serpentine indicates that space weathering introduces a bias in the interpretation of NIR remote sensing observations of phyllosilicates. The shift observed in our experiments can be detected by instruments on board Hayabusa2 and OSIRIS-REx, depending on the geometry of observation. Our findings provide support to the interpretation of such data.
HER-2 positivity is a high risk of recurrence of stage I gastric cancer
Authors: Kim Seonhoo , Kim Yeon-Ji , Chung Woo Chul
Published: November 2020

Background/Aims: The treatment of gastric cancer remains unsatisfactory. We aimed to investigate the prognostic value of immunohistochemical staining in gastric cancer.Methods: We analyzed 505 (279 early staged, 226 advanced-staged) gastric cancer tissues from patients who underwent radical gastric resection between January 2014 and December 2016. Available surgical specimens immunohistochemically stained for p53, epidermal growth factor receptor (EGFR), human EGFR 2 (HER-2), E-cadherin, and Ki-67 were reviewed. We evaluated the association between positivity to various biomarkers and disease recurrence, disease-free survival, lymph node metastasis, and microscopic lymphovascular invasion.Results: The median follow-up duration was 32.5 months (range, 7 to 70). Advanced gastric cancer cases showed high Ki-67 expression; other cases showed unremarkable expression. Concerning disease recurrence, lymphatic invasion, and disease-free interval, all biomarkers had no prognostic effects. HER-2-positive stage I gastric cancer tended to occur in old patients and in the upper one-third of the stomach (p = 0.01). HER-2 positivity was significantly correlated with disease recurrence (p = 0.01), lymphatic invasion (p = 0.03), and vascular invasion (p = 0.03) in stage I cases.Conclusions: Only HER-2 was associated with the recurrence of stage I gastric cancer. HER-2-positive stage I gastric cancer requires additional therapy despite curative resection.
RWRM: Residual Wasserstein regularization model for image restoration
Authors: He Ruiqiang , Feng Xiangchu , Zhu Xiaolong , Huang Hua , Wei Bingzhe
Published: November 2020

Existing image restoration methods mostly make full use of various image prior information. However, they rarely exploit the potential of residual histograms, especially their role as ensemble regularization constraint. In this paper, we propose a residual Wasserstein regularization model (RWRM), in which a residual histogram constraint is subtly embedded into a type of variational minimization problems. Specifically, utilizing the Wasserstein distance from the optimal transport theory, this scheme is achieved by enforcing the observed image residual histogram as close as possible to the reference residual histogram. Furthermore, the RWRM unifies the residual Wasserstein regularization and image prior regularization to improve image restoration performance. The robustness of parameter selection in the RWRM makes the proposed algorithms easier to implement. Finally, extensive experiments have confirmed that our RWRM applied to Gaussian denoising and non-blind deconvolution is effective.

Published: November 2020

In the present investigation, our aim is to define a generalized subclass of analytic and bi-univalent functions associated with a certain $q$-integral operator in the open unit disk $\mathbb{U}$. We estimate bounds on the initial Taylor-Maclaurin coefficients $\left \vert a_{2}\right \vert$ and $\left \vert a_{3}\right \vert $ for normalized analytic functions $f$ in the open unit disk by considering the function $f$ and its inverse $g = f^{{-}{1}}$. Furthermore, we derive special consequences of the results presented here, which would apply to several (known or new) subclasses of analytic and bi-univalent functions.

Published: November 2020

El taquínido norteamericano Trichopoda pennipes (Fabricius, 1781) es una especie parasitoide introducida en Europa, a consecuencia de su uso en el control de hemípteros plaga como Nezara viridula (Linnaeus, 1758). La captura de dos ejemplares en el municipio de Alicante (España) condujo a una revisión exhaustiva de la bibliografía e información disponible en bases de datos en línea sobre esta especie, con el fin de estudiar su distribución y fenología en el ámbito ibero-balear. El número de cuadrículas UTM de 10 × 10 km en las que se ha detectado T. pennipes se incrementa en un 90% con respecto a lo publicado hasta la fecha, con una gran cantidad de referencias fotográficas frente a otro tipo de citas (82:7). A través de este estudio, la Península Ibérica se convierte en la región europea donde está mejor caracterizada la distribución y fenología de esta especie exótica. Se pone de relieve la importancia que los bancos de datos fotográficos y la ciencia ciudadana tienen para el conocimiento de la biodiversidad.

Authors: Hamme Gilles Van , Waiengnier Maëlys , Bassens David , Hendrikse Reijer
Published: November 2020

Based on an analysis of the dynamics of advanced services in the Brussels economy, which account for more than a third of the total added value in BCR (Brussels-Capital Region), this article looks at the necessity for international attractiveness which accompanies the development of these services. Three reflections are developed in this framework. Firstly, given the international nature of the Brussels economy, the need as well as the possibility to strengthen the international economy linked to advanced services are examined. Next, the competition between the centre and the outskirts in the area of advanced services is examined. Finally, a critical analysis of the social impact of this economy is carried out, highlighting in particular the fact that these activities create few jobs.

Authors: Prabhakar Anjana , Abdulkhayarkutty Kabeer , Cheruvallil Shaji Velayudhan , Sudhakaran Prasanth
Published: November 2020

Background:

Exposure to high fluoride levels in drinking water can lead to a number of adverse effects in children, including cognitive dysfunction. Despite being endemic for fluorosis, studies on its effect on the cognitive function of children are lacking in Kerala.

Aims:

The aim of this study was to compare the cognitive function of school children with fluorosis with that of normal children and to correlate between the severity of dental fluorosis and cognitive function.

Settings and Design:

Cross-sectional study, conducted in collaboration with the National Fluorosis Control Programme, among school children in Alappuzha district, Kerala.

Methods:

Children aged 8–10 years, studying in 2 lower primary schools in Alappuzha district with confirmed fluorosis were selected, and compared with healthy age- and sex-matched children from the same school. Raven's Standard Progressive Matrices and MISIC digit span subtest were used to assess the cognitive function.

Statistical Analysis:

Continuous variables were assessed by independent samples t test and categorical variables by Chi-square test. The relationship between severity of dental fluorosis and grade of cognitive impairment was assessed using Spearman's correlation.

Results:

There were 60 children each in fluorosis and control groups. The mean age of the children was 8.95 ± 0.50. Only 15% of the children with fluorosis scored Grade I and II Raven's SPM grades (Intellectually superior/above the average) versus 30% in the control group. None of the children without fluorosis scored Grade V (intellectually impaired) category versus 20% in the fluorosis group. The mean digit span was significantly higher in the control group. A strong positive correlation between severity of dental fluorosis and Raven's SPM grades was found (Spearman's correlation coefficient = 0.740).

Conclusions:

Fluorosis is associated with impaired cognition in children. There is a positive correlation between severity of dental fluorosis and the grade of cognitive impairment.
Effects of Asset Allocation on Financial Performance of Unit Trust Schemes in Kenya
Authors: Mokaya Humphrey , Chogi Ronald , Nyamute Winnie
Published: November 2020

Abstract

Unit Trust Schemes provide diversification, liquidity, professional management among other benefits. In order to diversify the funds raised from various unit holders, fund managers adopt a criterion with which funds are allocated optimally. A descriptive research design was adopted, and the study period was 5-years. The ratio of the composition of different asset classes to the fund value was used as the independent variables. Fund age was used as the control variable. Sharpe ratio was used to measure investment returns and that represented the dependent variable of the study. Data was collected from secondary sources and a multiple linear regression model was adopted to assess the association of the variables. Collected data showed normality traits, positive autocorrelation when measured using Pearson correlation coefficients. The data also showed mixed results for multicollinearity tests. The weight of money market instruments, corporate bonds, treasury bonds and equity significantly affected performance of Unit Trust Scheme funds. They all had probability values in the interval of 0 and 0.05. Therefore, the study concluded that asset allocation significantly affects how a fund will perform. Other factors such as timing, manager experience and prevailing economic conditions have to be considered when evaluating performance of a fund.
Keywords: Asset allocation, Financial performance, Unit trust schemes, Kenya.
Verbalization of Precedent Thinking from the Perspective of Cross-Cultural Communication
Authors:   Nizhny Novgorod Linguistics University, Golubeva Nadezhda
Published: November 2020

Precedence as one of the most universal categories in our thinking enjoys unflagging interest among experts in humanities and social sciences. The purpose of the article is to prove the hypothesis about interparadigmality of precedent linguistics as a research field whose object is precedence units. This issue is specially relevant since the study of any manifestation of precedence in linguistic, cognitive, semiotic, and cultural projection has a high heuristic po-tential. The article contributes to the already existing body of knowledge by attempting to find similarities in the terms that are different in their linguo-philosophical meanings, namely: “precedence”, “cross-cultural communication” and “globalization,” as well as adapt new terms within the field of precedent linguistics. The article presents current scholarly debates about the specifics of precedent thought as that which ontologically predominates in the system of thinking which is realized by precedent units. It leads to the conclusion that any language system goes back to precedent thinking as something genetically precedent. It means that, as objects of linguistic analysis, precedent lin-guistic units are a prioiri devoid of any research prospects. Nevertheless, scholars’ interest to precedent units is explained not only by the worldview-related value of precedence phenomena, but also by the field of linguistic knowledge expressed by precedence units with the help of certain linguistic mechanisms in the realization of concrete linguistic processes. In this case one can see the opportunity of linking the object under research (precedent units) to other systems of scientific coordinates. For the analysis of precedent units we used a set of special and linguistic methods, namely: the method of precedence, precedent modeling, reconstructions of cognitive structures, transformation, etc. The research resulted in an increase of terms that are methodologically obligatory for prece-dent linguistics: a precedent reality, a precedent sentence, a precedent object, etc. Therefore, the following thesis was formulated: the cognitive nature of a precedent is a reproduced meaning which forms the basis of lexical, grammatical, and other language meanings. It is established that precedent units are semiotic signs of precedent thinking. They have a national and cultural identity and, simultaneously, a cross-cultural universality. In terms of linguistics, they also possess a global categorical status.
Word-Formation Categories in “The Tale of Bygone Years” (With a Focus on Nominal Suffixed Derivatives)
Authors:   Moscow State Linguistic University, Kunkova Alexandra
Published: November 2020

The article looks at word-formation categories in the “Tale of Bygone Years” from the cogni-tive perspective, specifically focusing on nominal suffixed derivatives as one of the most pro-ductive groups of derivative lexemes in the text of the manuscript. The author makes a num-ber of observations on the “internal form of the language” — i. e. specific forms of expression of thought and their grammatical realization as well as the creative and intellectual activity of human thinking. The primary purpose of the article is to determine the ratio of derivative and non-derivative nouns, to identify the most productive means of word formation, primary word-formation categories and their conceptual structure, and to analyze word-formation models that guide the process of cognition. We used content analysis to categorize common nouns in terms of their productivity/non-productivity and to determine word-formation mechanisms that are characteristic for the text. The statistical method was used to identify key word-formation methods and categories of nominal derivatives, while the descriptive-analytical method was used to describe their conceptual structure. In the course of the study, we identified primary word-formation categories which gave us a better idea of the medieval language consciousness which seems to have been characterized by an extensive system of word-formation suffixes. In particular, the word-formation act reveals a close interweaving of sensory and speculative perception and an interdependence of the structures of knowledge and evaluation of the world. In addition, the study revealed a high generative potential of core non-derivative concepts that underly the ancient Slavic language picture of the world. The results of the study confirm the hypothesis that the ancient man had developed abstract think-ing, and exteriorization of its conceptual system at all stages of its development was largely realized by original linguistic means. The theoretical significance of this research project lies in the synchronous study of word-formation processes as well as in applying axiological methods to the study of the linguistic picture of the world. Its practical conclusions throw fresh light at language as activity and demonstrate the high potential of original word-formation means of the Old Slavonic language. The results of this research can be used in theoretical courses in anthropo- and ethnolinguistics as well as in teaching Russian as a foreign language for advanced students.
Toponyms as Elements of Region-Specific Studies: Problems of Translation (Based on Crimean Toponymy)
Authors:   Sevastopol State University, Abramicheva Elena , Sokol Anna ,   Sevastopol State University
Published: November 2020

The article examines toponymic realia as a means of verbalizing lococentrism in region-specific discourse. Bilingual region-specific texts about Crimea and Sevastopol serve as material for analysing methods of pragmatic adaptation, used in translation of culturally significant toponymic realia that are part of the culturally meaningful vocabulary. As in any translation, when translating toponyms one must consider the primary purpose of translation. If that pur-pose is to ensure that foreign guests should easily find their way around a new linguistic and cultural space, the translator’s task will be to recreate the initial sound of toponyms so that foreign recipients may accurately and quickly identify local realia. Conversely, if the purpose of translation is to introduce foreigners to the local history and culture, the main task of the translator will be to render pragmatic meanings and culturally significant connotations of toponyms, paying particular attention to symbolic and axiologically important objects. After a comprehensive analysis of the material, we have concluded that the most efficient method that allows the translator to accentuate culturally valuable characteristics of toponyms is the “add-on” translation (when a specific culture-focused commentary is introduced into the translated text). In our work we used methods of contextual, semantic, conceptual, and comparative analysis to identify the pragmatic status and the degree of cultural importance of toponymic realia, and to determine the best way of their pragmatic adaptation in translation. The results of the study may be used by translators working with region-specific tourism-related literature, travel periodicals and websites, especially those that are dedicated specifically to Crimea and Sevastopol. The present study may also be helpful at the initial stage of pre-translation analysis when the translator has to determine the pragmatic function of the original text and the type of region-specific vocabulary predominant in it.

The impact of the development perspective of human resource management and lesson learned system of knowledge management on project success. The mediating role competency retention is examined by collecting the data from the regular employees of the telecommunication sector. A total of 380 questionnaires distributed, out of which 321 questionnaires were returned, and the study gained an actual response rate of 84.4%. Some surveys were excluded because of missing values using the list-wise deletion method, which includes a statistical analysis, and after that, 310 complete questionnaires were selected for further proceedings. The results confirmed that the development perspective of human resource management and lesson learned system of knowledge management has an insignificant positive relationship with project management competency retention and project success. There is no mediation of project management competency retention that has been proved between the development perspective of human resource management, and lesson learned system of knowledge management, and project success. A significant positive relationship has been shown between project management competency retention and project success. Finally, the results suggested that the organizations must retain competency to achieve project success.

Published: November 2020

How does? Market power effect the consumer purchase attention and buying behavior? To answer our research question in hypothetically and significant important perspective of price increase, we illustrate that (i) when the price increase is due to cost of goods sold consumer price fairness observation will decay with market power (ii) this fairness issue increase due to greater awareness of controllability of the firms with high market power (iii) when the price increase is not in the control of firms (and in this way saw as similarly reasonable for firms. with high and low market power). In our research above, predictions are empirically supported through quantitative studies of the survey. To address the research problem, we collect the data through convenience sampling from the consumers of Retail outlets. Our findings highlight how firm market power and pricing strategies influence the consumer awareness of price unfairness and the firm’s competition in the retail marketplace.

Published: November 2020

Generally, In Pakistan, people perceived that the quality of distance learning education is poor. Therefore, we decided to study to see if it's only people's opinion or legend. The study aims to analyze the association between instructor performance (IP), student-instructor interaction (SII), course evaluation (CE), and student satisfaction (SS) variables in distance education by taking Virtual COMSATS as a Case study. The target population of this research was the COMSATS (VIRTUAL CAMPUS). Students out of which 251 graduate and undergraduate students were selected as sample for current research. The purpose of this research study was to understand the key factors affecting student satisfaction in distance learning. Researchers also collect information through primary data using a survey questionnaire distributed through email to all the students of VCOMSAT. The literature review found that in distance learning education, student satisfaction is based on instructor performance, student-instructor interaction, course evaluation, Learning management system use, instructor attitude, etc. From the literature review, we found that course evaluation and instructor performance is very important for student satisfaction in distance learning. Researchers need to compare student's satisfaction with the subject wise. A comparison of practical subjects and without practical subjects needs to identify with student satisfaction. There is also required to compare lecturer motivation with student satisfaction and performance. Future research is also needed to compare the satisfaction of rural areas and urban areas students in distance learning education and the need to compare them with traditional education.

Published: November 2020

In this dynamic and technological world, leadership became the backbone of every organization. To understand this contemporary life cycle, the present study reflects the role of male and female leadership in the Private Education sector. The objectives of this study are (1) to investigate the direct and indirect effect of authentic leadership on knowledge sharing behavior through the mediation of commitment, and (2) to compare the gender disparity of leading an organization. Two models are proposed theoretically that test the direct and indirect relationship between authentic leadership and employees’ knowledge sharing behavior; tacit knowledge. This Study addresses two measurement models such as direct and indirect effects using Mplus (structural equation modeling). This study employed a quantitative research design. For this purpose, the study administers 455 survey Questionnaires among the private school teachers in district Shiekhupura, Pakistan but in turn, 377 proved validly and fully answered. The Study found the direct significant and positive relationships among authentic leadership, commitment, and employees’ knowledge sharing behavior. In addition, the study found the indirect significant and positive relationship between authentic leadership and knowledge sharing behavior that represents partial mediation. Moreover, this study reflects that the male gender leadership directly impresses teachers’ commitment and knowledge sharing more than female gender leadership. On the other way, female gender leadership indirectly influences knowledge sharing more than the male gender. So, it could say that the teachers were directly more committed and shared more knowledge by male gender leadership. But in the case of female gender leadership, the teachers give priority to the commitment and then share knowledge. Educational institutions should hire competent and efficient headteachers to facilitate the teachers in turn; there will be good collaboration among them about sharing knowledge. In addition, the teachers will be committed to their institution.

The Interplay of Risk Management and Uncertainty: A Project Management Practice Perspective.
Authors: Besner Claude , Hobbs Brian
Published: November 2020

THE PAPER EMPIRICALLY MEASURES THE INTERPLAY BETWEEN RISK MANAGEMENT AND UNCERTAINTY AND THE CONTEXTUAL VARIABILITY OF RISK MANAGEMENT PRACTICE. THE RESEARCH FIRST CLARIFIES THE CONCEPTS OF UNCERTAINTY, RISK AND RISK MANAGEMENT. THE RESEARCH DEFINES RISK MANAGEMENT FROM AN EMPIRICAL PERSPECTIVE I.E., FROM AN EMPIRICALLY IDENTIFIED SET OF TOOLS THAT IS ACTUALLY USED TO PERFORM RISK MANAGEMENT. THIS TOOLSET IS DERIVED FROM THE RESULTS OF AN ONGOING MAJOR WORLDWIDE SURVEY ON WHAT EXPERIENCED PRACTITIONERS ACTUALLY DO TO MANAGE THEIR PROJECTS. THIS PAPER USES A SAMPLE OF 1,296 RESPONSES FOR WHICH THE INTERPLAY BETWEEN RISK MANAGEMENT AND UNCERTAINTY COULD BE MEASURED. The results are very coherent. They verify and empirically validate many of the propositions drawn from a review of the literature. But results challenge some of the propositions found in the conventional project management literature and some commonly held views. The research shows that the use of risk management practices and tools is negatively related to the degree of project uncertainty. This somewhat counter-intuitive result is consistent with a general tendency for all project management tools and techniques to be used more intensively in better defined contexts. The dominant project management paradigm is oriented towards reducing or controlling uncertainty, but is less well adapted to unforeseeable events and high levels of uncertainty. A better understanding of the reality of the actual practice leads to a discussion about supplementing the current paradigm with new approaches to manage the uncertainty that cannot be removed or reduced by the conventional project management approach.

Published: November 2020

Today knowledge has become a crucial asset. Knowledge Management is a tool that nurtures and helps such assets to grow. It helps in effective utilisation of intellectual capital and enhancement of the organization’s performance. It involves blending the company’s internal & external information and transforms it into actionable knowledge. Organizations are turning to knowledge management initiatives and technologies to leverage their knowledge resources. It is important that everyone focuses on ownership of intellectual capital and utilize them efficiently for development as well as competitive edge with the help of appropriate tool. A Knowledge Management System (KMS) based on the state-of-the-art Information Technology (IT) makes that possible. Many experts believe that in future the main source of competitive advantage will be organization’s ability to leverage corporate knowledge, its distribution and to learn faster than others. Knowledge Management is an integrated systematic approach to identify, manage and share organization’s information assets available in databases, documents, policies, and procedures, as well as unarticulated expertise and experience held by individual workers. The idea behind KM is to capture not only explicit factual information but also the tacit information and knowledge that exist in an organization. The objective is to achieve the mission of the organization by sharing all types of knowledge among the employees of the organization. There are also lots of challenges as experts retire or leave organizations. Importance of knowledge database to capture expertise available for future reference and competitive edge has been felt by all. The paper is based on work of design and development of software “Information Portal at RDCIS”, developed for RDCIS – Research and Development centre of for Iron and Steel, SAIL. Today, knowledge is the strategic key resource. This paper is based on the challenges faced in the implementation of Knowledge Management system at RDCIS, SAIL. This paper focuses on the different forms of knowledge’s available in R&D Units, features, access mechanism, security mechanism, its implementation in different departments, and the platform used for implementing KMS.

Published: November 2020

Background and Objectives. Tuberculosis (TB) continues to be a public health concern in the Philippines. Vulnerablepopulations in congregate settings such as drug abuse treatment and rehabilitation centers (DATRCs) have higherrisks of TB transmission and infection. With the Duterte administration’s intensified campaign against illegaldrugs, government-retained DATRCs are filled to capacity. There is an identified need to profile drug users anddependents living in DATRCs. Furthermore, national guidelines for TB management specific to this population isabsent. A study was conducted to determine the profile of admitted clients diagnosed with TB, TB prevalence,treatment outcomes and choice of TB diagnostic modalities in six (6) Luzon-based DATRCs from 2013-2015.

Methods. All medical records of drug users admitted in this period were reviewed. Information on the totalpatient census was sought from DATRC heads and used to compute for prevalence.

Results. A total of 347 records were obtained. Overall TB prevalence in the study sites was 7,216 per 100,000population. The typical individual diagnosed with TB in a DATRC was male, with a mean age of 35 years, with at leasthigh school education, and unemployed. Weight loss and fatigue were the most common symptoms reported. Themajority (79.83%) completed TB treatment in the DATRCs. Sputum microscopy and chest x-ray were both used forTB diagnosis in 92.80% (322) of the cases.

Conclusion. The high burden of TB in Luzon-based, government-retained DATRCs is alarming and underscorethe critical need for standards and guidelines in the National Tuberculosis Control Program addressing the uniquecontext of these facilities.

Background. The features and outcome of hepatobiliary tuberculosis (HBTB) have not been extensively reportedin children.

Objective. To describe the clinical, biochemical, radiologic, microbiologic and histologic features and outcome ofchildren diagnosed with HBTB.

Methods. Data of HBTB patients aged 0-18 years were collected by review of medical records and as they wereadmitted. Cases were classified as bacteriologically-confirmed (positive AFB smear, TB culture or PCR of bile/livertissue) or clinically-diagnosed (clinical, histologic and/or radiologic evidence).

Results. A total of 36 patients were included (mean age: 13yrs; 64% males): three bacteriologically-confirmed and33 clinically-diagnosed. Most common signs/symptoms were weight loss (69%), fever (67%), hepatomegaly (61%)and jaundice (53%). Of the total, 68% had hypoalbuminemia, 50% increased transaminases and 47% prolongedprothrombin time. Fifteen (42%) patients were AFB positive on various microbiologic specimens. Most commonimaging finding was hepatic calcification (64%). Of 11 patients with liver biopsy, seven (64%) had chronic/granulomatous inflammation. All 36 were managed medically. Eight were lost to follow up, six died, and 22 (61%)are alive, nine with complete resolution of liver disease.

Conclusion. Hepatobiliary tuberculosis presents with non-specific clinical and biochemical findings. Severalinvestigations are necessary to confirm the diagnosis. Overall response to anti-TB treatment is satisfactory withpossible resolution of liver disease.

Traditionally, absorbing boundary conditions are used to limit the domains of numerical approximation of partial differential equations in infinite domains. In the present paper, the simplest of these conditions is used to obtain an analytical approximation of the solution to the problem of heat propagation in a one-dimensional infinite harmonic lattice consisting of two semi-infinite homogeneous sublattices with different mechanical characteristics.
