Tool Wear Condition Monitoring by Combining Variational Mode Decomposition and Ensemble Learning
Authors: Yuan Jun , Liu Libing , Yang Zeqing , Zhang Yanrui
Published: October 2020

Most online tool condition monitoring (TCM) methods easily cause machining interference. To solve this problem, we propose a method based on the analysis of the spindle motor current signal of a machine tool. Firstly, cutting experiments under multi-conditions were carried out at a Fanuc vertical machining center, using the Fanuc Servo Guide software to obtain the spindle motor current data of the built-in current sensor of the machine tool, which can not only apply to the actual processing conditions but, also, save costs. Secondly, we propose the variational mode decomposition (VMD) algorithm for feature extraction, which can describe the tool conditions under different cutting conditions due to its excellent performance in processing the nonstationary current signal. In contrast with the popular wavelet packet decomposition (WPD) method, the VMD method was verified as a more effective signal-processing technique according to the experimental results. Thirdly, the most indicative features that relate to the tool condition were fed into the ensemble learning (EL) classifier to establish a nonlinear mapping relationship between the features and the tool wear level. Compared with existing TCM methods based on current sensor signals, the operation process and experimental results show that using the proposed method for the monitoring signal acquisition is suitable for the actual processing conditions, and the established tool wear prediction model has better performance in both accuracy and robustness due to its good generalization capability.
Lightweight and Resource-Constrained Learning Network for Face Recognition with Performance Optimization
Authors: Li Hsiao-Chi , Deng Zong-Yue , Chiang Hsin-Han
Published: October 2020

Despite considerable progress in face recognition technology in recent years, deep learning (DL) and convolutional neural networks (CNN) have revealed commendable recognition effects with the advent of artificial intelligence and big data. FaceNet was presented in 2015 and is able to significantly improve the accuracy of face recognition, while also being powerfully built to counteract several common issues, such as occlusion, blur, illumination change, and different angles of head pose. However, not all hardware can sustain the heavy computing load in the execution of the FaceNet model. In applications in the security industry, lightweight and efficient face recognition are two key points for facilitating the deployment of DL and CNN models directly in field devices, due to their limited edge computing capability and low equipment cost. To this end, this paper provides a lightweight learning network improved from FaceNet, which is called FN13, to break through the hardware limitation of constrained computational resources. The proposed FN13 takes the advantage of center loss to reduce the variations of the between-class features and enlarge the difference of the within-class features, instead of the triplet loss by using FaceNet. The resulting model reduces the number of parameters and maintains a high degree of accuracy, only requiring few grayscale reference images per subject. The validity of FN13 is demonstrated by conducting experiments on the Labeled Faces in the Wild (LFW) dataset, as well as an analytical discussion regarding specific disguise problems.

After many years of TB ‘control’ and incremental progress, the TB community is talking about ending the disease, yet this will only be possible with a shift in the way we approach the TB response. While the Asia-Pacific region has the highest TB burden worldwide, it also has the opportunity to lead the quest to end TB by embracing the four areas laid out in this series: using data to target hotspots, initiating active case finding, provisioning preventive TB treatment, and employing a biosocial approach. The Stop TB Partnership’s TB REACH initiative provides a platform to support partners in the development, evaluation and scale-up of new and innovative technologies and approaches to advance TB programs. We present several approaches TB REACH is taking to support its partners in the Asia-Pacific and globally to advance our collective response to end TB.
Aiding Users in Green IS Adoption with Persuasive Systems Design
Authors: Shevchuk Nataliya , Oinas-Kukkonen Harri
Published: October 2020

Green information systems (IS) is a research domain that contributes to finding solutions for fostering environmental behavior in individuals, organizations, and communities. So far, researching Green IS for individual users has been less abundant and requires more insight. Users’ engagement with technologies start from adoption. Green IS challenges users to modify their lifestyles in order to achieve sustainable behavior patterns. This article is focused on persuasive Green IS, which have in-built features to convince users to modify their lifestyles and to improve technology adoption intention. In the theoretical background, main concepts, especially sustainable behavior, Green IS, IS adoption, persuasive systems, and persuasive systems design (PSD) model are presented. In this article, we analyzed three studies that focused on individual sustainable behavior change with persuasive Green IS. Overviews of these studies are presented and the studies were analyzed as a whole. The reviewed studies suggest that the PSD model has a high potential for becoming a tool for Green IS enhancement. The key themes identified from the studies bring value to both academics and practitioners, as well as suggest directions for researching the individual behavior change with persuasive Green IS in the future.
Törnqvist Formula for Сalculating a Consumer Price Index in Russia: Theory and Practice
Authors: Kozlova М. A.
Published: October 2020

The article reflects the author’s position on the adjustment of the so-called substitution bias, which affects the value of the consumer price index, currently calculated using the Laspeyres formula. The author proposes a solution to the problem of the adequacy of statistical measurements of the dynamics of consumer prices in the case when, as a result of changing cost of the consumer basket, a buyer replaces a relatively expensive product with a relatively cheaper one. This solution is based on the existing index construction methodology (axiomatic, economic and stochastic approaches). The article substantiates the use of the Törnqvist formula, which has better properties in comparison with other formulae used in the construction of superlative indices. The authors calculated the Törnqvist price index for Russia based on Rosstat methodology and data using country-level quarterly group price indices and shares of consumer spending. To evaluate the results of empirical testing Laspeyres price index was compiled using the same quarterly data as the Törnqvist index. The values of the Törnqvist price index in most cases are less than the price dynamics obtained according to the Laspeyres formula. This conclusion is proved both theoretically and empirically, and it is confirmed for Russia as well. However, due to the non-observance of the conditions of smooth trends in consumer prices, the difference between the values of the Törnqvist and Laspeyres indices is significantly larger in certain quarters than that presented in empirical studies in other countries. Consumer price index, calculated using the Törnqvist formula, in the system of indicators of price statistics in Russia can be defined as an indicator that specifies the main consumer price index. Calculation of its value is necessary for a more realistic description of the processes taking place in the consumer market.
Ficciones fundacionales argentinas en el teatro porteño contemporáneo
Authors: Noguera Lía
Published: October 2020

Durante el siglo XIX la literatura argentina configuró una serie de ficciones que se constituyeron en el paradigma literario para la fundación de saberes y discursos que procuraron sentar los cimientos de nuestra identidad política y cultural. Intelectuales como Hilario Ascasubi, Esteban Echeverría, Domingo Faustino Sarmiento, José Hernández, Eduardo Gutiérrez, entre muchos otros, delinearon el mapa literario decimonónico y propusieron discursos que circularon no sólo en el contexto del cual emergieron sino también se hicieron extensivos a los dos siglos que lo siguieron pero no sólo en el campo literario, sino también, en el teatral, el cinematográfico, el musical y en el de la danza. Dada esta productividad, nos interesa analizar en este artículo el modo en el que el teatro argentino actual se apropia, a partir de claves intermediales, de esas ficciones fundacionales con el fin de crear nuevos discursos y cuestionar ciertos paradigmas relacionados con la identidad política y cultural de la Argentina contemporánea. Para esto, nos concentraremos en el análisis de: Bufarra -carne a la parrilla- (2016-2018) de Eugenio Soto, Cosas como si nunca (2018), de Beatriz Catani y La vida extraordinaria (2018) de Mariano Tenconi Blanco.
THE STRUCTURE OF PHYLLOPHAGOUS INSECTS' COMPLEXES IN DECIDUOUS PLANTATIONS IN KHARKIV
Authors: Кардаш Є. С. , Соколова І. М.
Published: October 2020

The study was aimed to analyze the complexes of phyllophagous insect species with different ways of feeding on woody plants of certain genera. In 2017–2019, the research was carried out in street, park, and forest park plantations of Kharkiv on the material of woody plants of 13 genera: Tilia, Acer, Quercus, Ulmus, Populus, Aesculus, Robinia, Fraxinus, Betula, Sorbus, Salix, Alnus and Corylus. A total of 159 species of phyllophagous insects from 94 genera of 27 families of six orders were identified there. Representatives of Lepidoptera constitute 50.3% by the number of species, 50 and 51.9% by the number of genera and families, respectively, and Coleoptera – 35.8% of species, 28.7 and 22.2% of genera and families, respectively. The identified species of phyllophagous insects were divided into four groups based on the lifestyle and structure of the feeding apparatus of larvae: chewers, miners, galleries, and suckers. It was found that chewers and miners represent the orders Lepidoptera, Coleoptera and Hymenoptera, gallers – Hymenoptera and Diptera, suckers – Homoptera and Hemiptera. The suckers dominate by the number of species. The adventive species were found among the lepidopterous miners: Cameraria ohridella (Deschka & Dimic, 1986); Macrosaccus robiniella (Clemens, 1859); Phyllonorycter issikii (Kumata, 1963) and Parectopa robiniella (Clemens, 1863), as well as among the dipterous gallers, Obolodiplosis robiniae (Haldeman, 1847) was revealed. More than 30 similar species of phyllophagous insects were identified at typical forest plants, the most of them at the hazel (Corylus) and oak (Quercus) – 77 and 73 species (48.4 and 45.9% of all identified species), respectively. The similarity of the complexes of chewers from leaf beetles (Coleoptera: Chrysomelidae) at plants of certain genera is less than that of lepidopterous chewers, which is due to the biological characteristics of these insects. Thus, the polyphagia of lepidopterous chewers is explained by the limited ability of caterpillars to migrate in search of food at high population densities and severe defoliation of preferred plant species. Unlike lepidopterous caterpillars, the adults of leaf beetles are able to fly long distances in search of preferred plant species.

Authors: Hung Kevin KC , Walline Joseph H. , Chan Emily Ying Yang , Huang Zhe , Lo Eugene Siu Kai , Yeoh Eng Kiong , Graham Colin A.
Published: October 2020

Background: As health systems across the world respond to the coronavirus disease 2019 (COVID-19), there is rising concern that patients without COVID-19 are not receiving timely emergency care, resulting in avoidable deaths. This study examined patterns of self-reported health service utilization, their socio-demographic determinants and association with avoidable deaths during the COVID-19 outbreak. Methods: A cross-sectional telephone survey was conducted between March 22 and April 1, 2020, during the peak rise in confirmed COVID-19 cases in Hong Kong. Cantonese-speaking Hong Kong residents over 18-years-old were recruited using a computerised random digital dialling (RDD) system. The RDD method used stratified random sampling to ensure a representative sample of the target population by age, gender, and residential district. A structured self-reported questionnaire was used. Results: Out of 1738 placed calls, 765 subjects responded to the questionnaire (44.0% response rate). The factors associated with avoiding medical consultation included being female (37.2% vs. 22.5%, P<.001), married (32.8% vs. 27%, P=.044), completing tertiary education (35.3% vs. 27.7% (secondary) vs. 14.8% (primary), P=.005), and those who reported a "large/very large" impact of COVID-19 on their mental health (36.1% vs 30.5% (neutral) vs. 19.7% (very small/small), P=.047) using logistic regression analysis. Conclusion: Married females with both higher educational attainment and concern about COVID-19 were associated with avoiding healthcare services. Timely public communication to encourage and promote early health seeking treatment even during extreme events such as pandemics are needed.
High and Sustained Participation in a Multi-year Voluntary Performance Measurement Initiative Among Primary Care Teams
Authors: Mulder Carol , Rayner Jennifer
Published: October 2020

Background: The province of Ontario, Canada has made major investments in interdisciplinary primary care teams. There is interest in both demonstrating and improving the quality of care they provide. Challenges include lack of consensus on the definition of quality and evidence that the process of measuring quality can be counter-productive to actually achieving it. This study describes how primary care teams in Ontario voluntarily measured quality at the team level. Methods: Data for this 4-year observational study came from electronic medical records (EMRs), patient surveys and administrative reports. Descriptive statistics were calculated for individual measures (eg, access, preventive interventions) and composite indicators of quality and healthcare system costs. Repeated measures identified patient and practice characteristics related to quality and cost outcomes. Results: Teams participated in an average of 5 of 8 possible iterations of the reporting process. There was variation between teams. For example, cervical cancer screening rates ranged from 21 to 86% of eligible patients. Rural teams had significantly better performance on some indicators (eg, continuity) and worse on others (eg, cancer screening). There were some statistical but small changes in performance over time. Conclusion: High, sustained voluntary participation suggests that the initiative served a need for the primary care teams involved. The absence of robust data standards suggests that these standards were not crucial to achieve participation. The constant level of performance might mean that measurement has not yet led to improvement or that measures used might not accurately reflect improvement. The data reinforce the need to consider differences between rural and urban settings. They also suggest that further analysis is needed to identify characteristics that teams can change to improve the quality of care their patients experience. The study describes a practical, sustainable real-world approach to performance measurement in primary care that was attractive to interdisciplinary teams.
Doctor Retention or Migration: From Ireland to the World? Comment on "Doctor Retention: A Cross-sectional Study of How Ireland Has Been Losing the Battle"
Authors: Connell John
Published: October 2020

The recent study of prospective doctor migration and retention suggests that more than half of junior doctors intend to migrate from Ireland. While intent is not necessarily outcome, such intentions match similar survey results in Ireland and elsewhere. The rationale for migration is described as a function of difficult workplace circumstances (notably long hours and mismanagement). Lifestyle factors may however also be important for both migration and significant levels of return migration. These are related to family formation, and to an established culture of migration, that has contributed to a considerable circularity of mobility and migration, primarily between Anglophone countries. International migration may also have unspecified regional variations and impacts. Migration has taken a similar form for half a century and longstanding policies to constrain its more damaging impacts have been conspicuously unsuccessful yet responses remain urgent.

En la vertiginosidad actual la sociedad y las organizaciones están viviendo momentos de incertidumbre, riesgo y caos. Nos preguntamos ¿cómo se encuentran las organizaciones de cara a la pandemia? ¿Cómo reaccionan y deciden los directivos? ¿Qué rol ocupan los líderes? ¿Qué actitudes asumen? ¿Cómo responden los colaboradores? ¿Se implementan nuevas estrategias y prácticas de trabajo? ¿Cómo se asumen los nuevos cambios? Proponemos indagar los modos de entender y asumir el cambio por parte de los directivos y/o líderes empresariales, narrar las modalidades de trabajo y formas de adaptación de sus miembros en respuesta a los nuevos escenarios y comparar los tipos de empresas procurando realizar una primera aproximación del cambio organizacional en el presente. Resultó que el mayor escollo derivó del impedimento para trabajar, no por falta de adaptabilidad de las personas a la tecnología.La supervivencia de las organizaciones depende de varios factores, no solo de la capacidad de gestión en situaciones de crisis, por lo tanto no es factible aseverar la carencia de capacidades de conducción de sus directivos y/o líderes. En el mundo de las empresas y el trabajo, los cambios se aceleraron por y con la pandemia, dejando numerosos interrogantes en torno al impacto Pospandemia. ¿Podrán las organizaciones en crisis recuperarse? Las que queden en pie ¿cómo se verán afectadas en sus estrategias, culturas y estructuras?

Features of distribution and size-age composition of mackerel in the Norwegian Sea in the summer 2008–2018
Authors: Kalashnikov Y. N. , Seliverstova E. I.
Published: October 2020

The article analyzes the data on the size and age composition of mackerel during the sea expeditions on domestic fishing vessels in July-September 2008–2018. The features of the distribution of mackerel in the feeding period of its life cycle are Briefly studied. The information on areas of work of fishing fleet of Russia and features of its dislocation in the specified years is presented. It is noted that the main factors determining the nature of annual migrations, distribution of mackerel and its areas of thought in the Norwegian Sea are the features of the oceanographic situation and conditions of feeding in different years. It is shown that the change in the average length of fish in commercial aggregations is significantly influenced not only by the change of generations, but also by feeding conditions in the years under study, primarily the level of biomass of feed zooplankton in the Norwegian Sea. Distribution of mackerel in the Norwegian Sea in the summer period 2008–2018 confirmed the pattern, which was that large specimens of mackerel were feeding in the North and West of the sea, while small fish — much South and East. Feeding migrations of larger fish were earlier and longer.
Variability of hydrometeorological situation during fish kill events in the summer seasons of 2010–2018 in the Sea of Azov
Authors: Kochergin A. T.
Published: October 2020

Hydrometeorological situations during the fish kill events that took place in the Belosaray, Obitochny and Kazantip Bays in the summer seasons of 2010–2018 have been analyzed. Average monthly background water and air temperatures and wind velocity are considered, as well as their average daily values before, during and after a fish kill event. It is shown that background characteristics of water temperature and wind velocity influenced the development of a fish kill event more directly and definitely than air temperature, which influence was only indirect. In the majority of cases, hydrometeorological situation, leading to fish kill event, developed according to the typical pattern with increasing air and water temperature and decreasing wind activity. In the northern bays, the Belosaray and Obitochny Bays, fish kill events were recorded during the first half of summer season, and in the southern bay, the Kazantip Bay, they occurred in the second half of it. Since 2012, due to significant decrease in vertical thermohaline stability and increase in water homogeneity, no significant fish kill events were recorded under various temperature and wind conditions. Satellite imaging of sea surface temperature confirmed typical course of fish kill event development: the temperature increased in the pre-event period and then, after the event, stayed high in the southern bays and decreased in the northern ones.

Expectativas de inflación, riesgo país y política monetaria en México
Authors: Schwartz Rosenthal Moisés J. , Torres García Alberto
Published: October 2020

En este artículo se analiza el mecanismo de transmisión de la política monetaria en México y se destaca la importancia de las expectativas de los agentes económicos en dicho proceso. Los resultados del estudio indican que la política monetaria tendrá mayores posibilidades de propiciar una disminución de la inflación cuando no se limite tan sólo a restringir las condiciones monetarias a fin de compensar las presiones inflacionarias derivadas de mayores expectativas de inflación y de un incremento en la percepción de riesgo país, sino cuando la restricción monetaria más que compense dichos fenómenos. Dada la importancia de las expectativas en el proceso de abatimiento de la inflación, el Banco de México no sólo debe vigilar su comportamiento, sino también, a través de sus acciones, tratar de influir sobre ellas. El trabajo presenta evidencia de que las acciones restrictivas de la política monetaria en México disminuyen tanto las expectativas de inflación de los agentes económicos como la percepción de riesgo país. Asimismo, el análisis muestra que en el régimen monetario vigente en México, la intensidad de la restricción monetaria en un momento determinado se identifica a través de la evaluación conjunta del nivel objetivo de los saldos acumulados de las instituciones de crédito en el Banco de México (“corto”) y del comportamiento de las tasas de interés de corto plazo. De esta manera, aún en períodos en los que el "corto" no registra cambio alguno, las tasas de interés pueden señalar condiciones monetarias más o menos restrictivas.

SPIGELIAN HERNIA : A DIAGNOSTIC DILEMMA
Authors: Rai Shailendra , Mazumdar Basanti , Pratap Arvind
Published: October 2020

PURPOSE- Spigelian Hernia[SH] constitutes 0.12% to 2% of total abdominal wall hernia. The diagnosis of SH poses great difficulty because of non-specific presentation, and non obvious finding on examination. Also, Surgeons are less experienced with this entity and have low index of suspicion further contributing to underdiagnosis. Thus, whether SH is a rare entity or an underdiagnosed condition is debatable. The aim is share our experience and discuss different clinical aspects and outcomes of SH with a literature review regarding diagnostic difficulties.
PATIENTS AND METHODS- This is a case series of 18 patients diagnosed with 20 SH, were operated in a single surgical unit of Sir Sunderlal Hospital from January 2016 to July 2019. Historical patient’s records including demographic profiles, clinical presentation, and management were analysed.
RESULTS- Total 18 patients were admitted with women preponderance. The mean age of presentation was 39.23years. The most common presentation is pain followed by swelling. Most patients don’t have any clinical finding. Defect is identified only in 3 patients. Ultrasound, Contrast-Enhanced Computed Tomography and Magnetic Resonance Imaging were used to diagnose the hernia. All the patients were managed operatively with pre-peritoneal fat as the most frequent content.
CONCLUSION- SH is a diagnostic challenge with rather simple management. A high index of clinical suspicion is the key to diagnosis. SH seems more of an under-diagnosed rather than a rare entity. Also the author suggests to scan whole length of spigelian aponeurosis whenever there is a suspicion or the failure to reach an otherwise diagnosis.
A HOSPITAL BASED OBSERVATIONAL STUDY TO STUDY THE ASSOCIATION OF IRON DEFICIENCY ANEMIA WITH FEBRILE SEIZURES IN CHILDREN OF AGE GROUP 6 MONTHS TO 5 YEARS AT TERTIARY CARE CENTER, HYDERABAD
Authors: M Lakshmi , M Sumapriya , Anusha Channamsetty
Published: October 2020

BACKGROUND:
Febrile convulsion (FC) is the most common CNS disorder in childhood. 2-5% of children (or 4.8 out of every 1000) are affected every year. Studies conducted on the effect of iron deficiency on febrile convulsions found in children have yielded completely conflicting results. Iron deficiency has been a risk factor for febrile convulsions in some studies, while in others, it was proved to be protective against febrile seizure as iron deficiency increases the threshold of neuron excitation. Aims: To study the relationship between iron deficiency anemia and febrile convulsion in children to prevent the treatable cause of FC. Objectives: Is to determine the relationship between iron deficiency anemia and febrile seizures and to find out the incidence of anemia in the febrile seizure in males and females. Methods: A Hospital-based observational study carried out at Andhra Mahila Sabha Hospital, Hyderabad, during the period May 2014 to May 2016 involving children aged about 6months to 5 years of age group with typical febrile convulsions meeting inclusion and exclusion criteria. The temperature at admission and nutritional status was recorded, and investigations like hemoglobin, blood indices (MCV, MCH, MCHC), RDW (Red Cell Distribution Width), serum iron, and peripheral smear did for detection of iron deficiency anemia and their relationship with febrile seizure was observed.
Results: Out of 350 children enrolled, 131 (37.4%) were female, and 219 (62.6%) were males. In our study males was slightly more prone to febrile seizure with the ratio of M: F is 1.6:1. There is a significant association of iron deficiency anemia with FC, and there is increased frequency with increased incidence of iron deficiency anemia,(i.e.) seizures tend to repeat itself in the presence of iron deficiency anemia ( with P-value of <0.001, at CI of 95%).
Conclusion: low serum iron levels and the presence of anemia can serve as strengthening factors for febrile seizures in children. Accordingly, children with febrile seizures are suggested to be monitored for the diagnosis and treatment of IDA.

An accurate anterior guidance is important for proper function, aesthetics, comfort, and phonetics. Anterior guidance should be established with extreme caution while restoring anterior teeth as even a slight error in this regard can have detrimental effects on the entire stomatognathic system. This article describes the anterior rehabilitation of a 50-year-old patient who met with a road traffic accident and lost his upper anterior teeth. Anterior guidance developed in the provisional restorations was accurately recorded in the customized incisal guide table and permanent restorations were fabricated accordingly. Although the patient presented for the replacement of the fractured prosthesis, a comprehensive evaluation determined that a customized incisal guide table was needed to correct an array of dental issues. The treatment plan dramatically improved overall esthetics, comfort, and function.

Published: October 2020

Introduction– Tumors of parapharyngeal space are rare. Schwannomas, originating either from Schwann cells or fibroblasts supporting the nerve, are one of the benign neurological tumors occurring in this space. Surgical excision is the mainstay of its management. Transcervical approach is carried out for most of the parapharyngeal schwannomas. This article aims to study the clinical and radiological presentation of parapharyngeal schwannoma and also to study post-operative neurological outcome.
Materials and methods – A retrospective study was conducted from June 2018 to November 2019 (1.5 years) at the Department of Otolaryngology, in a tertiary care medical college & hospital. A total of 7 cases of parapharyngeal schwannoma were selected; the clinical, radiological presentation was studied. Post-operative complications were studied within a follow up period of 8 months.
Results – The mean age of presentation was 44 years. Male: Female ratio was 5:2. Five patients (71.4%) presented with left sided lesions whereas 2 patients (28.6%) were with right sided lesions. The most common presentation was an asymptomatic palpable neck mass in 4 patients (57.1%). 4 patients (57.1%) had mass arising from vagus nerve, 2 patients (28.6%) had mass arising from sympathetic trunk and one patient (14.3%) had mass arising from hypoglossal nerve. 4 patients (57.1%) had neurological complication in immediate post-operative period, out of which 3 patients (42.8%) improved within 8 months follow up.
Conclusion – Most of the parapharyngeal schwannoma presents with asymptomatic slow growing neck and/or oropharyngeal mass. Progressive growth can result in dysphagia. Surgical excision may accompany neurological complications. Outcome of neurological sequelae depends on preserving the anatomical integrity of the nerve from which the tumor arises.

Oligodontia is the congenital absence of six or more than six teeth in either permanent or primary dentition. Because of the missing teeth in these patient’s esthetic, functional and psychological problems may arise. Oral rehabilitation is recommended for the positive development of self-esteem as well as for improved speech, masticatory function and facial esthetics. Congenital absence of incisors may jeopardize the esthetic appearance of a child, especially during years of transition into adolescence. In such situations, interim restorations can be provided before any definitive treatment. This paper deals with the full mouth oral rehabilitation of an 11-year old child using a multidisciplinary approach involving acrylic crowns, 2*4 appliance, anterior functional space maintainer and direct composite restoration.

Introduction: Psychological and social effects of infertility may cause decline in the quality of life of infertile couples. A cross sectional study was conducted among 100 infertile couples, to find out the association between level of stress, anxiety and depression with their quality of life.
Materials and methods: Data was collected using demographic and fertility information questionnaire, depression anxiety and stress scale (DASS-42) and fertility quality of life (fertiQol-malayalam).
Results: Infertile couples experiences higher levels of depression, anxiety and stress and it is more among women,(depression-(15.36 +_ 9.23), stress(16.3+-7.52) anxiety (9.36+_6.33) than men (depression(12.52+_10.30 )(P=0.030), stress(12.84+_ 7.94 )(P=0-002 ) anxiety(7.50+_5-55). Levels of depression, anxiety and stress have significant negative relation with their quality of life. Infertile women has significantly lower quality of life (P= 0.002) than men.
Conclusion: Interventions, to reduce depression, anxiety and stress among infertile couples may be helpful to improve their quality of life.

Introduction – Total knee arthroplasty is considered as one of the most painful procedures in field of orthopedic surgery. In this study we intended to evaluate the analgesic efficacy of Local Infiltration Analgesia (LIA) with post-surgical single shot of adductor canal block in terms of good post-operative analgesia and early post- operative mobilization thus allowing faster rehabilitation and recovery and thereby improving the final outcome of TKA in long term.
Material and method- A total of 60 patients were enrolled, 30 in each group. Group A received Standard General anesthesia & postoperative analgesia with a single shot of adductor canal block with 20cc of 0.25% ropivacaine along with intraoperative local infiltration analgesia. Group B also received Standard General anesthesia & postoperative analgesia with a single shot of adductor canal block with 20cc of 0.25% ropivacaine but intraoperative local infiltration analgesia was not administered in group B.
Result- Group B patients required a greater number of rescue analgesic doses in comparison to Group A patients. The majority of the patients in Group A had early postoperative mobilization in comparison to Group B (p=0.003). Mean preoperative and 6-week postoperative WOMAC scores showed that difference was statistically significant (p=0.034), showing a significantly lower 6-week postoperative WOMAC score in Group A in comparison to Group B.
Conclusion – Our study gives us a conclusion that intraoperative Local Infiltration Analgesia along with single shot of adductor canal block provides better post-operative pain relief & allows early mobilization of the patient thus enhancing the rehabilitation thereby improving the final outcome of the Total Knee Arthroplasty.
Relación entre motivación y rendimiento académico de los estudiantes de Administración de Empresas
Authors: González Cardona Marjorie Azucena
Published: October 2020

Se sostiene en diversas teorías y modelos que los estudiantes difieren entre sí, en su manera de pensar y actuar ante el hecho de estudiar, lo que da lugar a conducirse de una u otra manera cuando estudia y a hacerlo por motivos diferentes. Basado en ello, se pretende mostrar los resultados de la investigación orientada hacia conocer ¿Cuál es la relación que existe entre la motivación y el rendimiento académico de los estudiantes de la carrera de Administración de Empresas, plan fin de semana, del Centro Universitario de Oriente? Para abordar este propósito se hizo uso de la escala llamada CEAP-48 elaborada por Barca (2005), y para la variable rendimiento académico se utilizó el modelo matemático elaborado por Luque y Sequi, (2002) el cual considera los indicadores de regularización, aprobación y logro cognitivo, vinculado con la duración teórica de la carrera y el tiempo de permanencia real. Bajo un alcance de investigación correlacional se relacionó la motivación de los estudiantes vista desde la motivación académica y las atribuciones causales, con la variable rendimiento académico. Se tuvo acceso en el proceso de investigación a 313 estudiantes que representan el 91.78% de la población estudiantil de dicha carrera. Los resultados obtenidos, permitieron aceptar la hipótesis general planteada Ho = A mayor nivel de motivación, mayor rendimiento académico se muestra en los estudiantes de la carrera de Administración de Empresas, plan fin de semana, del Centro Universitario de Oriente. Esto con una correlación positiva alta (Sig.=0.000, p= 0.753). Significa que el 50.70% de la varianza en el rendimiento académico de los estudiantes, puede explicarse por la variación en la motivación que éstos muestran. Además, los datos indican que el 66.8% de los estudiantes son impulsados por una motivación profunda.
