Authors: Hassan Uzma
Published: June 2019

Objectives: To evaluate cervical cancer awareness among females of reproductive age group. Study Design: Descriptive Cross-sectional study. Setting: Gynecology OPD of Rawal General and Dental Hospital, Islamabad. Period: Six months; March to September 2016. Methods: Total 200 females of reproductive age group (15-49 years) were included (patients and their attendants), by using the non-probability convenience sampling. A semi structured questionnaire was filled by interview method by the researcher. Questions were related to awareness of females regarding cervical cancer. The response was noted in ‘Yes’ and ‘No’ and they were calculated in percentages. Results: Married females (56%), majority (45%) belonged to 27-38 years of age group, and maximum (46%) had intermediate education. Response in ‘Yes’ was; Heard about cervical cancer (68%), Heard about pap smear test (32%), Had pap smear test (5%), HPV is most common cause of cervical cancer (26%), HPV can spread through direct sexual contact (40%), Multiple sexual partners increase risk of cancer (64%), Smoking increase risk of cancer (40%), Vaccines available to prevent cervical cancer (38%). Cervical cancer be prevented by following all measures (40%), Never heard about Pap smear test (58%). Majority did not know how often pap smear test be done (43%). Both genders should have vaccine (55%). By following all the measures awareness of cervical cancer can be increased (48%). Conclusion: In this study awareness of cervical cancer along with its prevention was quite low in the women of reproductive age group. Insufficient knowledge of HPV infection was the reason of cervical cancer. The females were inadequately aware of the indications and significance of cervical cancer screening. Majority believed that Pap smear is performed only on the symptomatic women. The knowledge of women about the recipient of cervical cancer screening was poor.

THE PRINCIPLES OF NECESSITY AND SUFFICIENCY TO SYSTEMATIZE SOFTWARE
Authors: Аршинский Вадим , Arshinskiy Vadim , Аршинский Леонид , Arshinskiy Leonid , Бахвалов Сергей , Bakhvalov Sergey
Published: June 2019

The paper presents a possible approach to the systematization (including classification) of modern software. Most authors in the systematization implicitly proceed from the principle of sufficiency: the program is enrolled in a particular class based on what it can do, what tasks it is able to solve. This blurs the boundaries of the classes, since the same program object sometimes corresponds to different tasks. The paper proposes to proceed from the principle of necessity: the program belongs to the class, what tasks it needs to solve. Then the secondary capabilities of the software recede into the background and are not taken into account in the classification. The relationship of necessity between the software objects themselves is also taken into account. This allows you to organize software objects, stratifying them according to principles of the mutual need. Moreover, different types of necessity are introduced: existential, functional and target, with a hierarchy between them. The latter allows you to keep the hierarchy of necessity, when program objects are mutually necessary for each other, but in a various senses. As a result, a hierarchy is built inside the software similar to the known one: hardware, system software, application software, but with its own characteristics. In particular, the software tool designed for creating software objects, splits into two layers: the tools to create custom programs to compile and tools for creating interpreted programs type. Accordingly, the application software is stratified. In general, the principle of necessity should be considered as an approach to classification, allowing to make a certain order in the question of systematization of software and its division into classes.

Published: June 2019

MES systems are one of the tools of The industry 4.0 concept. MES systems plan technological operations performed at certain workplaces. The main tasks solved by systems of this class include optimization, operational planning, production process management, operational recalculation of the production schedule. Mechanism used in MES-systems for calculating production schedules allows to take into account the interrelation of all elements of the operational plan, to ensure the choice of alternative technological routes and the adaptive mode of material flow management. MES allows you to simulate different production situations, for example, to calculate the optimal load of the equipment in the event of a machine failure. It allows to plan the production schedule in case of need of carrying out planned or extraordinary repairing of the equipment. The production schedule in the MES system is visualized using a Gantt chart.In the Russian Federation, MES-systems are increasingly recognized.MES systems are especially in demand in enterprises with multi-level technological processes, which depend on many factors.When implementing the MES-system in the technical control department, the data of defective products obtained by measuring any parameters on the measuring equipment are transferred to the MES-system. Next, the production schedule is recalculated in order to optimally load the machine-tool fleet. Thus, the introduction of the MES-system can improve the efficiency of the entire enterprise.

Authors: Hamzah Jenan Abdulhasan , Nima Mohammed A.
Published: June 2019

The influence of adding metal foam fins on the heat transfer characteristics of an air to water double pipe heat exchanger is numerically investigated. The hot fluid is water which flows in the inner cylinder whereas the cold fluid is air which circulates in the annular gap in parallel flow with water. Ten fins of metal foam (Porosity = 0.93), are added in the gap between the two cylinder, and distributed periodically with the axial distance. Finite volume method is used to solve the governing equations in porous and non-porous regions. The numerical investigations cover three values for Reynolds number (1000 ,1500, 2000), and Darcy number (1 x10-1, 1 x10-2, 1x10-3). The comparison between the two case with and without insertion the metal foam fins are examined in this study. Results show that the temperature of the inner pipe wall is affected by the Reynolds number, water inlet temperature, Darcy number variation. The resulting values and the behavior of the local and average coefficient of heat transfer are presented. The improvement in the mean coefficient of heat transfer (hm) is found to be 129 % with the using of the metal foam fins.

Issues of Privilege in University Service-Learning
Authors: Lee Tina , Buchanan Elizabeth , Berg Devin R.
Published: June 2019

Service-learning activities, such as development projects organized under the Engineers Without Borders USA organization, are popular on many university campuses as a mechanism for providing applied, global learning experiences for both engineering and non-engineering students. Existing studies have found that these experiences are meaningful for students and help them to apply what they learn in the classroom to the “real world” while learning valuable teamwork, communication, project management, and other skills. In this paper, we report on our ongoing research about EWB-USA participation and outcomes and, using case studies from our ethnographic research, discuss barriers to EWB-USA project participation among less privileged students. The implications this issue has for institutions interested in using service-learning to meet core learning outcomes as well as the need to diversify service-learning will be considered.

Economic growth is a process of increasing per capita output that occurs continuously in the long run. Economic growth is one indicator of the success of development. Increasingly increasing economic growth usually increases people's welfare. While economic development is an effort to increase per capita income by processing potential economic forces into the real economy through investment, increasing knowledge, increasing skills, using technology, adding management skills and organizing.Economic growth is also related to the increase in "per capita output". The theory must include theories about GDP growth and theories about population growth. Then the third aspect is economic growth in a long-term perspective, that is, if for a long period of time the per capita output shows an increasing tendency.The distribution of income distribution in Indonesia is increasingly uneven. This can be seen from the increasing Indonesian Gini Index. As is known, the Gini index measures the income distribution of a country. The size of the Gini index Between 0 (zero) to 1 (one), the Gini index Equal to 0 (zero) indicates the index that the income distribution is perfectly equal, while the Gini index is 1 (one ) shows that the income distribution is totally uneven. Based on the data, the Indonesian Gini index continues to increase from year to year.The state of income distribution in Indonesia since 1970 can be said not to improve, this is caused by many factors, including the First production factor market (input market) which is the increase in labor supply which results in excess labor, low labor wages and limited employment opportunities in urban areas resulting in unemployment and urban slums.Second, land ownership. Land distribution is the main determinant of the extent of poverty and income distribution.

Economic growth is the process of increasing per capita output in the long run. economic growth only discuss about how much output growth or how much gnp is received without questioning the largest source of contribution from the total output received. So it is not surprising if one of the development indicators cannot be used as a reflection of the distribution of income of a country. It is also not surprising, when a country experiences growth, the country will also face the problem of inequality in income distribution, so that the rich the richer the poor the poorer they become.

Identifying Situational, Individual, and Demographic Determinants of Social Anxiety Using a Naive Bayesian Classification Algorithm
Authors: Krieg Alexander , Okamura Kelsie , McMillan Charmaine Higa
Published: June 2019

Social situations may play a role in the conceptualization and treatment of social anxiety disorder. However, situational variance is rarely examined and has not yet been directly compared to dispositional or demographic variance. We used situation-sampling methodology and naive Bayesian classification to determine the predictive power of situational features compared to individual and demographic variables. In Study 1, a sub-sample of 309 undergraduate students responded to random subsets of 680 situations to train a machine-learning algorithm that predicted whether a participant would endorse situational social anxiety. The predictions were then tested on the remaining participants in order to generate accuracy estimates. Situational variance alone improved accuracy by 21.39% (from 50%) whereas the addition of individual variance (+3.8%) and demographic information (-1.11%), did not add to the predictive accuracy. Situational features were rank-ordered by their likelihood ratios, and were grammatically edited to reflect the top, middle, and bottom features. In Study 2, a community sample of 211 people responded to these new situations and endorsement rate was compared to predictive accuracy estimations. We found consistent accuracy for high and middle social anxiety-provoking situations indicating that situational features may be particularly relevant when treating clients with higher levels of anxiety.
Learning Representations by Humans, for Humans
Authors: Hilgard Sophie , Rosenfeld Nir , Banaji Mahzarin R. , Cao Jack , Parkes David
Published: June 2019

We propose a new, complementary approach to interpretability, in which machines are not considered as experts whose role it is to suggest what should be done and why, but rather as advisers. The objective of these models is to communicate to a human decision-maker not what to decide but how to decide. In this way, we propose that machine learning pipelines will be more readily adopted, since they allow a decision-maker to retain agency. Specifically, we develop a framework for learning representations by humans, for humans, in which we learn representations of inputs (‘advice’) that are effective for human decision-making. Representation generating models are trained with humans-in-the-loop, implicitly incorporating the human decision-making model. We show that optimizing for human decision-making rather than accuracy is effective in promoting good decisions in various classification tasks while inherently maintaining a sense of interpretability.
Impaired sensitivity to temporal fine structure but not the envelope for children with mild-to-moderate sensorineural hearing loss
Authors: Halliday Lorna , Rosen Stuart , Tuomainen Outi , Calcus Axelle
Published: June 2019

Psychophysical thresholds were measured for 8-16 year-old children with mild-to-moderate sensorineural hearing loss (MMHL; N = 46) on a battery of auditory processing tasks that included measures designed to be predominantly reliant upon frequency selectivity, and sensitivity to temporal fine structure (TFS) or envelope cues. Children with MMHL who wore hearing aids were tested in both unaided and aided conditions, and all were compared to a group of normally hearing (NH) age-matched controls. Children with MMHL performed more poorly than NH controls on tasks considered to be dependent upon frequency selectivity, sensitivity to TFS, and speech discrimination (/bɑ/-/dɑ/), but not on tasks measuring sensitivity to envelope cues. Auditory processing deficits remained regardless of age, were observed in both unaided and aided conditions, and could not be attributed to differences in nonverbal IQ or attention between groups. However, better auditory processing for children with MMHL was predicted by better audiometric thresholds and, for aided tasks only, higher levels of maternal education. These results suggest that, as for adults with MMHL, children with MMHL may show deficits in their frequency selectivity and sensitivity to TFS, but that sensitivity to envelope cues may remain intact.
Psychometric Network Analysis of the Hungarian WAIS
Authors: Schmank Christopher J. , Goring Sara Anne , Kovacs Kristof , Conway Andrew R. A.
Published: June 2019

The positive manifold—the finding that cognitive ability measures demonstrate positive correlations with one another—has led to models of intelligence that include a general cognitive ability or general intelligence (g). This view has been reinforced using factor analysis and latent variable models. However, a new theory of intelligence, Process Overlap Theory (POT; Kovacs & Conway, 2016), posits that g is not a psychological attribute but an index of cognitive abilities that results from an interconnected network of cognitive processes. From this perspective, psychometric network analysis is an attractive alternative to latent variable modeling. Network analyses display partial correlations among observed variables that demonstrate direct relationships among observed variables. To demonstrate the benefits of this approach, the Hungarian Wechsler Adult Intelligence Scale Fourth Edition (H-WAIS-IV; Wechsler, 2008) was analyzed using both psychometric network analysis and latent variable modeling. Network models were directly compared to latent variable models. Results indicate that the H-WAIS-IV data was better fit by network models than by latent variable models. We argue that POT, and network models, provide a more accurate view of the structure of intelligence than traditional approaches.

Authors: Pérez Céspedes Natalia , Sainz Mejías Amaya , Camacho Solís Ana Elena
Published: June 2019

El síndrome de hiperestimulación ovárica es una de las complicaciones iatrogénicas más serias de las técnicas reproductivas asistidas. Dicho síndrome está mediado por la liberación exagerada de factores vasoactivos por parte de las células de los folículos ováricos desarrollados mediante la estimulación ovárica controlada, y se caracteriza principalmente por aumento de tamaño ovárico junto con el desplazamiento de líquido y proteínas del espacio intravascular hacia un tercer espacio. Su diagnóstico es principalmente clínico, apoyado en la ecografía pélvica, y su manejo depende de la clasificación según su severidad. Es posible identificar a las pacientes en riesgo de presentarlo, y se deben aplicar estrategias preventivas previo, durante y posterior a la implementación de técnicas reproductivas asistidas para disminuir el riesgo de presentar esta complicación.
Analgesia espinal-epidural combinada versus epidural durante la labor de parto: efectos sobre el feto y el parto
Authors: Solar Del Valle Thania
Published: June 2019

El dolor durante la labor de parto puede provocar diferentes respuestas que pueden llegar a ser perjudiciales tanto para la madre como para el feto. La analgesia neuroaxial ha demostrado ser el método más efectivo para el control del dolor durante el parto. La epidural y la combinación espinal-epidural son las técnicas más comunes de administración de analgesia neuroaxial. Múltiples estudios han analizado las reacciones adversas de estas técnicas, comparando sus efectos sobre la perfusión uteroplacentaria mediante la medición de contracciones uterinas, frecuencia cardíaca fetal y la necesidad de realizar una cesárea de emergencia debido a estas alteraciones. Al comparar los resultados obtenidos en estos estudios se pudo demostrar que, a pesar de que las pacientes a las que se les administró analgesia mediante combinación de espinal-epidural presentaron mayores alteraciones en la frecuencia cardíaca fetal, esto no aumentó de manera significativa las complicaciones perinatales. Se ha demostrado que estas alteraciones son transitorias y que, si se reconocen y se tratan oportunamente, no aumentan la morbimortalidad materna ni fetal.

Las masas ováricas, de trompas uterinas y de tejidos conectivos aledaños, se conocen como masas anexiales y son un problema ginecológico común. Pueden encontrarse en todas las edades y existen diferentes subtipos. Los más comunes en mujeres premenopáusicas son los tumores de células germinales, de los cuales el teratoma maduro es el más frecuente. Al evaluarlas, siempre deben descartarse emergencias quirúrgicas y signos de malignidad. El ultrasonido es el método radiológico de elección para estudiar una masa anexial. Esta revisión bibliográfica se enfoca en el abordaje inicial de una masa anexial y la diferenciación por ultrasonido de lesiones benignas y malignas. Cuando se sospechan lesiones malignas o en pacientes muy sintomáticas, el abordaje es quirúrgico y con el objetivo de preservar la fertilidad.

Los inhaladores de nicotina han demostrado ser igual de eficaces que el resto de formas comerciales de TSN. El Bupropión, inicialmente comercializado como antidepresivo, mostró ser altamente efectivo en el cese del fumado, además de controlar la ganancia de peso durante el proceso. La Vareniclina es tratamiento de más alta eficacia, mostrando superioridad sobre la TSN y el Bupropión, debido a su efecto dual sobre receptores nicotínicos de acetilcolina.

ABSTRACT: Lipase enzyme originated from wheat germ was immobilized on nylon -6- grafted with polyglycidyl methachrylate (PGMA). The immobilization of enzyme experiments were designed and studied using face centred central composite design (FCCCD) under response surface methodology (RSM). Prior to immobilization, the polymer was activated with diethyl amine/ethanol to introduce an amine functional group to facilitate covalent bonding with the enzyme. The immobilized and free enzymes were characterized for effect of temperature and pH on enzyme activity, stability, storage and reusability as well as kinetics studies. ANOVA revealed that optimum lipase activity of 0.287 U/ml was achieved at immobilization time of 5 h, pH of 6 and 1.0 mg/ml for enzyme concentration. The optimum temperatures and pH for immobilized and free enzymes were 45 °C and 35 °C, and 8 and 7, respectively. The immobilized enzyme showed higher stability compared to free enzyme. The immobilized enzyme retained 18% of its activity after being recycled 8 times. In a storage stability test, immobilized lipase was able to retain 70% of its activity after being stored for 30 days, while free enzyme activity dropped to 15 % after 20 days of storage.

Enzim pegun ini direka dan dikaji secara eksperimen menggunakan reka bentuk campuran pusat pada permukaan (FCCCD) di bawah kaedah tindak balas permukaan (RSM). Sebelum menjadi pegun, polimer ini telah diaktifkan dengan dietil amine/ethanol bagi menghasilkan kumpulan fungsi amine bagi membantu ikatan kovalen atom pada enzim. Enzim pegun dan bebas ini telah dikategorikan mengikut kesan enzim ke atas suhu, aktiviti enzim ke atas kesan pH, kestabilan, keboleh-simpanan dan keboleh-gunaan balik, serta ujian tindak balas kinetik. ANOVA membuktikan bahawa aktiviti optimum enzim lipase ini adalah sebanyak 0.287 U/ml telah terhasil selama 5 jam pegun, pada pH 6 dan kepekatan enzim sebanyak 1.0 mg/ml. Suhu dan pH optimum, pada enzim pegun dan enzim bebas ini adalah pada 45 °C dan 35 °C, dan pH 8 dan 7, masing-masing. Enzim pegun ini menunjukkan lebih stabil daripada enzim bebas. Enzim pegun dilihat kekal 18% daripada aktivitinya selepas 8 kali ulangan. Melalui ujian kestabilan simpanan, enzim lipase pegun dapat mengekalkan 70% daripada aktivinya selepas disimpan selama 30 hari, manakala aktiviti enzim bebas telah menurun kepada 15% selepas 20 hari dalam simpanan.

ABSTRACT:  Liquefaction phenomenon is generally caused by high dynamic vibrations in a very fast duration. This article investigated the behavior of dynamic vibrations caused by vehicles on the road. This study employed the HVSR (Horizontal Vertical Spectral Ratio) with an accelerometer. The result of dynamic vibration generated by the passing vehicle or the micro tremor / micro seismic vibration was recorded by seismic monitoring devices. This seismic monitoring equipment converted vibration into natural frequency (f0) and amplification (A0) using Geopsy software. The result of HVSR (Horizontal Vertical Spectral Ratio) was the soil vulnerability index (Kg). The results of this study indicated that the three parameters above were then analyzed with the assumption that if the amplification value (A0) was higher and associated with a lower natural frequency value (Æ’0) with a high vulnerability index (Kg), then the area had the potential liquefaction, with laboratory research results in the form of granular gradation testing as the supporting data. Therefore, the results of the analysis and the laboratory can concluded that the three research locations have the potential liquefaction.

ABSTRAK: Fenomena pececairan umumnya disebabkan oleh adanya getaran dinamik tinggi dalam tempoh yang sangat cepat. Artikel ini mengkaji fenomena getaran dinamik yang disebabkan oleh kenderaan di jalan raya. Kajian ini menggunakan HVSR (Nisbah Spektral Menegak Mendatar) dengan pecutan. Hasil getaran dinamik yang dihasilkan oleh kenderaan yang melalui atau gegaran mikro / mikro getaran seismik dicatatkan oleh alat pemantauan seismik. Peralatan pemantauan seismik ini mengubah getaran ke frekuensi semula jadi (f0) dan amplifikasi (A0) menggunakan perisian Geopsy. Hasil HVSR (Nisbah Spektral Vertikal Mendatar) adalah indeks kelemahan tanah (Kg). Keputusan kajian ini menunjukkan bahawa ketiga-tiga parameter di atas kemudian dianalisis dengan anggapan bahawa jika nilai amplifikasi (A0) lebih tinggi dan dikaitkan dengan nilai kekerapan semulajadi yang lebih rendah (Æ’0) dengan indeks kelemahan tinggi (Kg), maka kawasan mempunyai potensi pencairan, dengan hasil penyelidikan makmal berupa pengujian gradasi granular sebagai data pendukung. Oleh itu, hasil analisis dan makmal dapat menyimpulkan bahawa tiga lokasi penyelidikan mempunyai potensi adanya pececairan.

Published: June 2019

A grid-tied, single stage, three phase, PV system provides higher efficiency than a two-stage PV system. This paper presents a three-phase, single stage, grid-connected PV system with MPPT and reactive power injection capability into the grid using modified capacitor assisted extended boost quasi Z-source inverter (MCAEB q-ZSI) as the grid-tied PV inverter. The adaptability of the inverter for irradiance changes and the boost factor control with its shoot-through duty ratio adjustment made it highly recommended for the grid system. The shoot-through control technique like maximum constant boost control with a third harmonic injection enhances the performance of the inverter by reducing the low order ripples and voltage stress. The fuzzy voltage controller is proposed with the capacitor linearization algorithm to regulate the DC-link voltage. The current approach uses a fuzzy controller to control the real and the reactive power injection into the grid. The performance evaluation of the fuzzy and PI grid controller is carried out for the constant irradiance condition and from the investigation, parameters like boost factor (B), the shoot-through duty ratio(Ds), real power (P), reactive power (Q),  power factor and harmonics in the current injection are determined. A laboratory setup of the PV powered grid system is implemented, tested and validated with the simulation results.
