Dialogue Testing
Authors: Lunden A. O.
Published: May 2020

Dialogue testing refers to individual oral impromptu presentations of specific questions, topics, or problems from the subject matter of a course. Tape recorded answers provide: (i) a semipermanent record for grading and evaluation; (ii) practical experience in oral presentation and handling of a microphone; (iii) the opportunity to evaluate responses by other students; and (iv) self‐evaluation by subsequent reply of the taped responses. Dialogue testing develops, as a primary objective, a learning experience to the student, and as a secondary objective, an acceptable means of evaluation by the instructor. This method was used experimentally in a junior‐level grain crops course in the fall semester of 1970. The most effective technique was to assign specific questions, provide at least 5 min for preparation, and allow 1 to 3 min for each response. Subject matter knowledge, understanding and presentation of principles of the course, and general growth of the student's confidence and oral communication were highly satisfactory. The method appears to have considerable merit for many teaching situations, as it provides the student with much needed experience in oral presentation, develops meaningful understanding of the subject matter, and allows effective evaluation.

A Theoretical Evaluation of Group Behavior on Social Media
Authors: Özdemir Osman
Published: May 2020

On social media in the digital era, individuals can easily reach out and comment to everyone on everything. Introducing themselves, exchanging opinions and participating in discussions are more likely on social media. They have provided the opportunity to benefit from others or to benefit others as a member of a group. On the other hand, social media have become a sociological field where one or a group can share every moment and make comments to everyone, including those they do not know. It is also seen as an area where the privacy limit is weakened and respect for rules decreases. In this context, group behavior, social media and related topics are discussed in this chapter including the definition, benefits and effects of the group; evolution, functions, classification and the importance of social media; the effects of social media and the group on social capital, social cohesion and social intelligence; and factors determining group behavior on social media.
Recent Advancements in Pathogenesis, Diagnostics and Treatment of Alzheimer’s Disease
Authors: Khan Sahil , Barve Kalyani H. , Kumar Maushmi S.
Published: May 2020

Background:

The only conclusive way to diagnose Alzheimer’s is to carry out brain
autopsy of the patient’s brain tissue and ascertain whether the subject had Alzheimer’s or any other
form of dementia. However, due to the non-feasibility of such methods, to diagnose and conclude
the conditions, medical practitioners use tests that examine a patient’s mental ability.

Objective:

Accurate diagnosis at an early stage is the need of the hour for initiation of therapy. The
cause for most Alzheimer’s cases still remains unknown except where genetic distinctions have
been observed. Thus, a standard drug regimen ensues in every Alzheimer’s patient, irrespective of
the cause, which may not always be beneficial in halting or reversing the disease progression. To
provide a better life to such patients by suppressing existing symptoms, early diagnosis, curative
therapy, site-specific delivery of drugs, and application of hyphenated methods like artificial intelligence
need to be brought into the main field of Alzheimer’s therapeutics.

Methods:

In this review, we have compiled existing hypotheses to explain the cause of the disease,
and highlighted gene therapy, immunotherapy, peptidomimetics, metal chelators, probiotics and
quantum dots as advancements in the existing strategies to manage Alzheimer’s.

Conclusion:

Biomarkers, brain-imaging, and theranostics, along with artificial intelligence, are
understood to be the future of the management of Alzheimer’s.

Authors: Guarnieri Renzo , Miccoli Gabriele , Seracchiani Marco , D’Angelo Maurilio , Di Nardo Dario , Testarelli Luca
Published: May 2020

Objectives:

The progressive peri-implant bone remodeling caused by dynamic cycles of microdamage may change peri-implant bone characteristics and volume after the functional loading.

This prospective study was designed to evaluate the radiographic trabecular bone density and peri-implant vertical dimensional changes around the non submerged dental implant with a laser-microtextured collar (NSLI)s after 5 years of functional loading.

Methods:

Digital periapical radiographs of 58 NSLIs supported fixed single crowns and fixed partial dentures in 26 patients (14 men, mean age of 52 ± 3.8 years) were used for comparative evaluation between the implant placement [Baseline (BSL)], the definitive Crowns Delivery (CD) and the 5 years post-functional loading examination (T5). Regions of interest (ROI) were taken into consideration for the measurement of mean gray levels, standard deviation, and variation coefficient. The texture parameters, such as contrast, correlation, angular second moment and entropy, were investigated by using the software ImageJ (v.1.50i), by means of the Gray-level Co-occurrence Matrix (GLCM) Texture Tool plugin. Vertical Peri-implant Marginal Bone Level (VPMBL) was assessed at the mesial and the distal sides of each implant by subtracting the measure at BSL from the measure at T5 by means of dedicate software (VixWin Platinum Imaging Software). Mixed regression models were adopted to analyze data. The possible effects of some variables, such as the use of provisional denture, location, crown/implant ratio, type of prosthetic design (single or splinted), on radiographic dimensional vertical changes, gray levels and texture analysis variables were also evaluated.

Results:

From BSL to T5, mesial and distal VPMBL showed a statistically significant gain of 0.9 ±0.5, and 0.10 mm ±0.6, respectively (P<0.05). From CD to T5, mean gray levels increased from 94.4±26.8) to 111.8±27.1 (P<0.05), while the coefficient of variation decreased from 0.08±0,03 to 0.05±0.04) (P<0.05). Variables showed no statistically significant correlation with texture parameters (P > 0.05).

Conclusion:

NSLIs showed an increase in radiographic vertical peri-implant marginal bone levels and bone density up to 5 years of loading.

Authors: Marascio Nadia , Mazzitelli Maria , Scarlata Giuseppe G.M. , Giancotti Aida , Barreca Giorgio S. , Lamberti Angelo G. , Divenuto Francesca , Costa Chiara , Trecarichi Enrico M. , Matera Giovanni , Liberto Maria C. , Torti Carlo
Published: May 2020

Background:

Hepatitis C Virus (HCV) infection is associated with a high risk of developing liver diseases. Globally, HCV prevalence is changing due to improving health care procedures, population movement, and availability of new antiviral therapy. In Italy, data on the prevalence of HCV infection are insufficient, out-dated, and restricted to specific areas.

Objective:

Between 2008 and 2018, we investigated HCV antibody (Ab) seroprevalence and genotypes distribution among patients presenting for testing at our Teaching Hospital.

Methods:

The HCV Ab and genotyping assays were performed by routine diagnostic methods. Chi-square for linear trend was carried out by OpenEpi (v3.01).

Results:

Among 120,009 consecutive patients, 5877 subjects were HCV Ab positive (4.89%). During the observational period 2008-2018, prevalence decreased significantly (p<0.001) from 4.7% in 2008 to 3.6% in 2018. HCV1b was the most prevalent subtype (47.2%) followed by HCV2a/2c (20.2%), and HCV3 (9.7%), while HCV4 showed a rate of 6.1%. HCV infection was more frequent in males (55.4%) than in females (44.6%). Overall, most infected patients were born before 1949.

Conclusion:

Epidemiological analyses are important to understand the evolution of the HCV epidemics under the influence of several factors, such as risk behaviour and therapy with direct-acting antivirals.
Contrast-enhanced Magnetic Resonance Imaging Revealing the Joint Capsule Pathology of a Refractory Frozen Shoulder
Authors: Ando Akira , Hagiwara Yoshihiro , Sekiguchi Takuya , Koide Masashi , Suzuki Kazuaki , Kanazawa Kenji , Itoi Eiji
Published: May 2020

Background:

Frozen shoulder (FS) is clinically diagnosed on the basis of patients’ medical history and physical examination. Its confirmation is based on joint capsule and coracohumeral ligament thickening, subcoracoid fat obliteration, and joint capsule contrast enhancement on magnetic resonance imaging (MRI). We performed bilateral contrast-enhanced MRI (CE-MRI) in FS patients to compare the outcomes with those of their unaffected contralateral counterparts.

Methods:

Ten patients (3 men, 7 women, median age: 54.5 years) with unilateral FS, requiring arthroscopic capsular release after failed conservative treatment, were included. The median forward elevation, abduction, external rotation, and internal rotation of the 10 patients were 100°, 60°, 7.5°, and the buttock, respectively. The median visual analog scale score was 5.3, and American Shoulder and Elbow Surgeons (ASES) score was 42. Bilateral CE-MRI was simultaneously performed on the day before surgery, and MRI findings were compared between FS and contralateral healthy shoulders (controls).

Results:

Significant axillary pouch enhancement and rotator interval were observed in all FS, but not in the unaffected comparable sides (p=0.002, respectively). The thickness of the axillary pouch (FS: 4.8 mm, C: 4.4 mm, p=0.58), coracohumeral ligament (FS: 3.9 mm, C: 4.1 mm, p=0.33), and subcoracoid fat obliteration (p=1.00) were not significantly different between FS and controls.

Conclusion:

CE-MRI aids in the clinical diagnosis of FS. However, axillary pouch joint capsule and coracohumeral ligament thickening or subcoracoid fat obliteration differences were not characteristic findings when contralateral shoulders were compared.
Development and Validation of Instrument to Measure Thinking Patterns: A Structural Equation Modeling Analysis
Authors: Maksum Ali , Khory Fifukha D.
Published: May 2020

Background:

As an instrument that measures thinking processes, the cognitive reflection test still has a number of problems, especially in terms of its validity and reliability.

Aims:

This research aimed to develop instruments to identify patterns of thinking that meet psychometric requirements.

Methods and Results:

Participants in the research were 727 students from the State University of Surabaya, including 322 (44%) men and 405 (56%) women with a mean age of 19.17 years. The first examination using exploratory factor analysis showed that the scale of thinking patterns, which we later called Intuitive-Reflective Scale (IRS), had a conceptual relations structure consisting of 5 factors with a loading factor of .40 - .80. The five factors explained 52.57% of the total variance and had Cronbach’s Alpha reliability of .71. The second examination using confirmatory factor analysis based on structural equation modeling proved that the IRS had factors structure that was consistent with the results of the first examination and was a significant predictor of academic performance.

Conclusion:

Hypothesized factor structure fits with empirical data based on the comparative fit index of .96 and root mean square error of approximation of .07.
Ultimate Behaviour of Perforated Steel Plate Girders Subjected to Shear Loading
Authors: Bahrami Alireza , Najarnasab Mahdi
Published: May 2020

Background:

The Perforated Steel Plate Girders (PSPGs) are those Steel Plate Girders (SPGs) that have openings in their web. The PSPGs are significant structural members to withstand bending mainly. The proper combination of steel plates is applied to fabricate the PSPGs. When the available rolled steel profiles cannot carry the applied loads, the use of beams made of the steel plates is unavoidable.

Objective:

The present paper presents the ultimate behaviour of PSPGs subjected to shear loading.

Methods:

In order to carry out the study, the finite element method is used as a practical design tool for predicting the ultimate behaviour of the PSPGs under shear loading. Two experimentally tested PSPGs are selected to conduct the modelling accuracy using ABAQUS. All the features of the tested specimens are considered in the modelling. The finite element modelling results are compared with the experimental tests results, which verify the modelling. Since the accuracy of the modelling is demonstrated, thereafter, the method is used for the nonlinear analysis of the developed PSPGs having different circular and rectangular openings. Various parameters are adopted in the analysis to vastly evaluate their effects on the ultimate behaviour of the PSPGs. The parameters include shape of the openings (circular and rectangular openings), number of the openings (2 and 4 openings), arrangement of the openings (horizontal and vertical openings), using steel frame around the openings, utilising diagonal steel stiffeners to connect the steel frame to the corners of the PSPGs, and thicknesses (2 mm and 4 mm) of the steel frame and the diagonal steel stiffeners.

Results:

The obtained results from the nonlinear analysis of the PSPGs are summarised considering various parameters. The results are compared and discussed, taking into account the effects of the parameters on the ultimate behaviour of the PSPGs.

Conclusion:

The study highlights that the shape of the openings affects the behaviour of the PSPGs. Accordingly, circular openings are preferred compared with the rectangular ones. Also, as the number of the openings is increased, the ultimate capacity of the PSPGs is reduced. The behaviour of the PSPGs is considerably affected by the arrangement of the openings in which the horizontal openings have better performance than the vertical ones. If the steel frame and/or the steel stiffeners are utilised, the ultimate capacity is enhanced. The ultimate capacity of the PSPGs is improved by increasing the thickness of the steel frame and/or stiffeners. The failure modes of the PSPGs with circular and rectangular openings are indicated and evaluated.

Authors: Martini Rachel , Carvalho Jorge , Arêde António , Varum Humberto
Published: May 2020

Background:

In this study , a methodology based on non-destructive tests was used to characterize historical masonry and later to obtain information regarding the mechanical parameters of these elements. Due to the historical and cultural value that these buildings represent, the maintenance and rehabilitation work are important to maintain the appreciation of history. The preservation of buildings classified as historical-cultural heritage is of social interest, since they are important to the history of society. Considering the research object as a historical building, it is not recommended to use destructive investigative techniques.

Objective:

This work contributes to the technical-scientific knowledge regarding the characterization of granite masonry based on geophysical, mechanical and neural networks techniques.

Methods:

The database was built using the GPR (Ground Penetrating Radar) method, sonic and dynamic tests, for the characterization of eight stone masonry walls constructed in a controlled environment. The mechanical characterization was performed with conventional tests of resistance to uniaxial compression, and the elastic modulus was the parameter used as output data of ANNs.

Results:

For the construction and selection of network architecture, some possible combinations of input data were defined, with variations in the number of hidden layer neurons (5, 10, 15, 20, 25 and 30 nodes), with 122 trained networks.

Conclusion:

A mechanical characterization tool was developed applying the Artificial Neural Networks (ANN), which may be used in historic granite walls. From all the trained ANNs, based on the errors attributed to the estimated elastic modulus, networks with acceptable errors were selected.

Authors: Metekiya Workua M. , Wondafrash Dawit Z. , Tesfaw Mekonnen T.
Published: May 2020

Background:

Mental illness is the leading cause of disability all over the world greatly impacting several vulnerable groups particularly people living with the Human Immunodeficiency Virus (HIV). Depression is the most common mental illness especially in people with human immunodeficiency virus and its prevalence is increasing rapidly in the world at an alarming rate among this group population.

Objectives:

The main aim of this study was to investigate the prevalence and severity of depressive symptoms and related factors among patients living with the Human Immunodeficiency Virus

Methods:

An institutional-based cross-sectional study design was conducted among 398 Human Immunodeficiency Virus patients. Patient Health Questionnaire (PHQ-9) and Logistic regression analysis were used to determine predictors of depressive symptoms.

Results:

A total of 398 patients with the diagnosis of HIV were enrolled in the present study, whereby the majority were females (275, 69.9%). Prevalence of depressive symptoms among HIV-positive patients was 43.5% (95% CI: 38.2, 48.7). In multivariate analysis, poor sleep quality (AOR: 5.72, 95% CI: 3.52,9.27), Poor social support (AOR: 1.95, 95% CI: 1.15,3.29), lack of education status (AOR: 4.10, 95% CI: 1.92,8.76) elementary school (AOR: 2.46,95% CI: 1.26,4.79) and high school educational status (AOR: 2.11,95% CI: 1.01,4.42) were positively associated with depressive symptoms in people living with the Human Immunodeficiency Virus.

Conclusion:

The prevalence of depression symptoms was found to be significantly high in patients living with HIV. Patient’s poor sleep quality, poor social support and lower educational status were found to be dependent predictors of depressive symptoms. Hence, it is important to conduct more interventions to assess the depressive symptoms among HIV patients.

Authors: Sharma Pooja , Pahuja Sharvan Kumar , Veer Karan
Published: May 2020

Background:

Over recent years, the security of the publicly available audio, video and
text data has become a big challenge, i.e., social media communication; hence the author presents
an exceedingly secure communication system to hide the data from an attentive adversary.

Objective:

The study aims to design and analyze a novel algorithm to be implemented for message
transmission using multi-image LSB steganography and crucial variable-length cryptography. Encoder,
decoder and social media as a channel are the main parts of the study.

Methods:

Various computer techniques like cryptography and steganography with video handling
are used to perform the proposed work. The main objective of this work is to implement the raw
video as the cover on the QR code image. This image is to be transmitted as information by enshrouding
it in the raw footage. Additionally, encryption of QR code image using VLMKG (Variable
Length Mixed key Generation) cryptography enhances the reliability of work. The variablelength
Key is generated separately to implement the cryptography. Multi-image LSB steganography
is imposed with one-bit replacement in the spatial domain. Wavelet Transform (Daubechies
family) is applied for denoising, which enhances the accuracy of the received data.

Results:

The proposed work provides a secure way to transmit any information in the form of QR
code image successfully. It is verified with the help of five QR Code images and three raw video
groupings.

Conclusion:

Implementation of LSB steganography, variable-length key cryptography and
MATLAB usage had superbly extracted the image features; calculations and the consequences
were observed to be palatable.
Oral Sex Knowledge and Experience of Transgender Youth: An Opportunity for Dental Education
Authors: Macdonald David W. , Grossoehme Daniel H. , Mazzola Amanda , Pestian Teresa , Schwartz Scott B.
Published: May 2020

Recent evidence suggests that, when compared to their cisgender counterparts, transgender youth exhibit more unsafe sexual behavior that may elevate their risk for sexually transmitted infections. The aim of this study was to better understand what transgender youth know about oral sex, related consequences, and mechanisms of protection and where they obtained this information. The findings can be helpful in preparing oral health providers to play a role in meeting this public health need. The study took place at a U.S. academic pediatric medical center in 2017. Participants were recruited at a Transgender Research Day and during Transgender Clinic sessions. English‐speaking transgender adolescents ages 14 to 24 were invited to participate in a previously validated survey about their knowledge and behaviors related to oral sex. Of the 138 transgender youth invited to participate, 57 completed the surveys, for a 41% response rate. Most respondents reported feeling they understood the necessity of protection and consequences of oral sex but did not use protection. Over half of the participants (58%) said they had not had a physician, dentist, or parent speak to them about oral sex. Given the lack of standardized, evidence‐based sex education, it is imperative that adolescents, particularly in highly vulnerable populations like transgender youth, receive accurate information about oral sexual contact. Dental schools should prepare future practitioners to address these issues with youth using a culturally competent, evidence‐based approach.

Kendali Adaptif Neuro Fuzzy PID untuk Kestabilan Terbang Fixed Wing UAV (Adaptive Control of Neuro Fuzzy PID for Fixed Wing UAV Flight Stability)
Authors: Irmawan Erwhin , Eko Prasetiyo Erwan
Published: May 2020

Unmanned Aerial Vehicle (UAV), especially fixed wing, are widely used to carry out various missions, namely civil and military missions. To support the implementation of this mission, it is necessary to develop an intelligent automatic control system (autopilot). In this paper, an autopilot system with adaptive neuro fuzzy PID control is developed to control lateral (pitch) and longitudinal (roll) motion, by taking advantage of PID, fuzzy, and neural network control. Therefore, robust controls which can handle non-linear conditions can be formed. This paper aims to determine the performance of adaptive control of neuro fuzzy PID controllers for longitudinal and lateral motion on UAV. The result shows that adaptive control of neuro fuzzy PID are able to control the lateral and longitudinal motion of the aircraft and able to compensate for interferences from environmental disturbances in flying condition, such as changes in direction and wind speed that causes changes in aircraft attitude. The control characteristics of neuro fuzzy PID adaptive control in lateral and longitudinal motion are relatively similar. Adaptive control of neuro fuzzy PID has better performance than fuzzy PID control, i.e., faster settling time and lower percentage of maximum overshoot.
Antena Susun Berpolarisasi Sirkular dengan Menggunakan Distribusi Daya Dolph Tschebycheff (Circularly Polarized Array Antenna Using Dolph Tschebycheff Power Distribution)
Authors: Zaskia Pratiwi Citra , Munir Achmad
Published: May 2020

This paper discusses the design and realization of circularly polarized array antenna using Dolph Tschebycheff power distribution. The advantages of implementing circular polarization yield the array antenna suitable for outdoor communication system and can minimize the Faraday effect. The Dolph Tschebycheff power distribution is used to suppress the side lobe of array antenna. The proposed array antenna, which is intended to operate at the frequency of 5.3 GHz, consists of five square patch elements with seven diagonal slots upon each element to enhance the bandwidth and to produce the circular polarization. The array antenna is designed and realized using two layers of FR-4 epoxy dielectric substrate with the dimension of 119 mm × 44.1 mm and the thickness of 0.8 mm for each dielectric substrate. Each patch element is fed using a proximity coupling technique excited through a 50 Ω SMA connector. The measurement results show the bandwidth of 720 MHz, the side lobe level of 12.39 dB, the gain of more than 6 dBi around the frequency of 5.3 GHz, and the 3 dB axial ratio bandwidth of 200 MHz. It seems that the realized array antenna could produce wide bandwidth, low side lobe level, and circular polarization, so that it is suitable for WLAN application.
Applying Metacognitive Theory in Teaching Vietnamese Reading Skills to Foreign Students
Authors: Hong Chuyen Nguyen Thi
Published: May 2020

Since the late 1970s, the term “metacognition” has been used to generalize the thinking process of each individual in his or her own thinking. Theoretical contents of metacognition such as: understanding knowledge and thinking of oneself; monitoring and evaluating their cognitive processes; trying to adjust the cognitive process when solving problems... have brought a new perspective in teaching to promote the role of learners and make the process of learning turn the training process into self-training process. Within the scope of this article, we introduce briefly metacognitive theory in teaching Vietnamese reading skillto foreign students.
The U.S. Canned Soup Market: A Competitive Profile
Authors: Datta Y.
Published: May 2020

This paper follows the path of eight studies of U.S. markets: Men’s Shaving Cream, Beer, Shampoo, Shredded/Grated Cheese, Refrigerated Orange Juice, Men’s Razor-Blades, Women’s Razor-Blades, and Toothpaste.Porter associates high market share with cost leadership strategy which is based on the idea of competing on a price that is lower than that of the competition. However, customer-perceived quality—not low cost—should be the underpinning of competitive strategy, because it is far more vital to long-term competitive position and profitability than any other factor. So, a superior alternative is to offer better quality vs. the competition.In most consumer markets a business seeking market share leadership should try to serve the middle class by competing in the mid-price segment; and offering quality better than that of the competition: at a price somewhat higher, to signify an image of quality, and to ensure that the strategy is both profitable and sustainable in the long run. Quality, however, is a complex concept that consumers generally find hard to understand. So, they often use relative price, and a brand’s reputation, as a symbol of quality.In 2008 the U.S. retail sales for the Canned Soup market were $3.44 Billion. The market leader Campbell had a commanding share of 52.5%, followed by a far-distant second Progresso with a share of 17.8%. A notable feature of this market was the tremendous variety of soups, albeit many with minor variations, that equaled the unbelievable figure of 1011!We focused our attention on the two best-selling varieties of soup: (1) Chicken Broth canned, the market leader, with 11.1% market share, and (2) Chicken Noodle Soup canned, with a 7.4% share. Within each variety we chose the can-size range with the highest sales.Using Hierarchical Cluster Analysis, we tested Hypotheses I that a market leader is likely to compete in the mid-price segment. Employing U.S. retail sales data for 2008 and 2007, we found that for both Chicken Broth and Chicken Noodle Soup—for 2008 and 2007—the market leader Campbell was a member of the mid-price segment.For Hypothesis II we wanted to test the proposition that the unit price of the market leader would be somewhat higher than that of the nearest competition. For Chicken Broth we could not test this hypothesis because Progresso, the runner-up, could not be included in this analysis.However, for Chicken Noodle Soup the results did not support the hypothesis because Progresso happened not to be a part of the mid-price, but that of the premium segment.Finally, we discovered four strategic groups in the industry.
SMART Antimicrobial Resistance Goals to Drive Meat Safety Improvement
Authors: Schmidt John William
Published: May 2020

Concerns that food-animal production significantly contributes to antibiotic-resistant human infections have persisted for more than 20 years. Most antibiotic resistance concerns are generalized, not specific. By their nature, non- specific concerns are unfalsifiable and can never be scientifically alleviated or remediated. Therefore, antibiotic resistance meat safety improvement begins with defining SMART (Specific, Measurable, Attainable, Relevant, and Time bound) antibiotic resistance goals. Two SMART goals related to high-priority antibiotic resistance in beef production are described as an example to facilitate scientific goal attainment

ULOGA VATIKANA I RKC U LIKVIDACIJI I RIMOKATELIČENjU SRBA U ”NDH”
Authors: Gacinovic Radoslav
Published: May 2020

U granicama ustaške ”NDH” bilo je oko 5 miliona katolika Hrvata, oko 1.900.000 pravoslavnih Srba i oko tri četvrtine miliona muslimana. Od prvog dana neprijateljske okupacije i fašističko-ustaške strahovlade započeta je besomučna hajka na pravoslavne stanovnike ”NDH”. Srbi pravoslavni stavljeni su, može se reći, izvan zakona.

La costa sur del estado de Nayarit (México) es escenario de un acelerado cambio de uso de suelo, en buena medida enfocado hacia el desarrollo de infraestructura turística y residencial; dado lo anterior es imprescindible contar con información de campo sobre la ocurrencia de especies de vida silvestre en determinadas áreas. Con el objetivo de conocer la diversidad de la avifauna asociada a los humedales costeros del sur de Nayarit, durante 2007 se realizaron observaciones de campo por puntos fijos y en transectos de banda al interior de diez humedales, complementado con información bibliográfica y avistamientos en AverAves. Se determinó una riqueza de al menos 167 especies, de las cuales 16 están incluidas en alguna categoría de riesgo (NOM-059) y 20 con algún tipo de endemismo. En los humedales de Boca de Tomates y El Quelele se observó la mayor riqueza específica, siendo las aves playeras el grupo más diverso (27 especies); y además se registró la anidación de 16 especies de aves. Se constató la importancia de estos humedales para la continuidad de los procesos ecológicos de las aves. Esta diversidad se ve amenazada por el desarrollo urbano en la región. Lo anterior implicaría implementar medidas urgentes hacia a un manejo integral de la costa.

Los hidrogeles basados en colágeno son redes tridimensionales (3D) con la capacidad de absorber agua y una alta biocompatibilidad para utilizarlos en la reparación de tejidos dañados. Estos materiales presentan pobres propiedades mecánicas y velocidades de degradación rápidas, limitando su aplicación a estrategias de ingeniería tisular y biomedicina; por ésto, la incorporación de fases inorgánicas en la matriz 3D del colágeno como la hidroxiapatita ha contribuido en la mejora de sus propiedades, incrementado la eficiencia de los hidrogeles híbridos obtenidos. Este trabajo, presenta las contribuciones más relevantes relacionadas con los sistemas de hidrogeles basados en colágeno y partículas de hidroxiapatita dispersas dentro de la matriz colagénica, lo que evidencia que la combinación de los materiales no altera la biocompatibilidad y biodegradabilidad típicas del colágeno, permitiendo la adhesión, proliferación, crecimiento celular y control del metabolismo de las células implicadas en los procesos de una reparación ósea, presentando a los hidrogeles como una estrategia para su uso potencial en la ingeniería tisular.
