Published: October 2020

Object detection and tracking are essential and testing undertaking in numerous PC vision appliances. To distinguish the object first find a way to accumulate information. In this design, the robot can distinguish the item and track it just as it can turn left and right position and afterward push ahead and in reverse contingent on the object motion. It keeps up the consistent separation between the item and the robot. We have designed a webpage that is used to display a live feed from the camera and the camera can be controlled by the user efficiently. Implementation of machine learning is done for detection purposes along with open cv and creating cloud storage. The pan-tilt mechanism is used for camera control which is attached to our 3-wheel chassis robot through servo motors. This idea can be used for surveillance purposes, monitoring local stuff, and human-machine interaction.

Mobile Ad hoc Network (MANET), which is comprised of a number of self-organized and battery equipped mobile nodes, is used widely in different applications, like private sectors and military. However, security is a major issue in MANET routing, as the network is prone to attacks. The main objective of intrusion detection system is for categorizing normal and suspicious activities in network. This paper introduce the intrusion detection scheme for establishing the secured path in MANET. For mobile ad hoc networks, swarm optimization approach based novel intrusion detection system is proposed in this paper. The proposed system is based on Cat swarm optimization (CSO) for detecting, one of vey possible attack, i.e. packet dropping attack in mobile ad hoc networks. Also Failure node discovery can be optimized by considering nodes historical information along with the neighbor node information. Before using the swarm optimization for findingsensor node’s trust values and for improving provenance data transmission security, an Extend the secure provenance scheme with Side Channel Monitoring – Information gaining ability (SCM) for detecting packet drop attacks staged by malicious data forwarding nodes is used. It assist in finding presence of selfish nodes as well as packet drop behaviours. With low false positive rate and high true positive rate, packet dropping attacks are detected effectively using proposed technique as shown in simulation results.

In the recent era, voltage reduction procedure is gaining most attention for achieving minimum energy consumption. Full adder is the primary computational arithmetic block in numerous of the computing executions and hence is the critical component of ALU.Various existing full adders proposed in literature fail to accomplish low power delay product (PDP) and lacks driving strength when used in chainsstructure.In this paper two new hybrid full adders have been proposedwith an aim to achieve low PDP.Further the paper proposesripple carry adder (RCA) in chainstructure using triplet design approach to improve the driving strength. Fivedifferent hybrid full adders topologies have been implementedto build 4-bit RCA adder in regular and triplet logic design and PDP improvement is obtained in triplet design approach. All the simulations are done on 45nm technology and performance analysis done over the voltage range 0.6 V to 1.2V in Cadence Virtuoso simulation software. Simulation results are obtained to show that delay and PDP has improved in triplet designing and the proposed hybrid adders represents least PDP among other implemented reference circuits.

“A STUDY OF MICROALBUMINURIA IN NON DIABETIC HYPERTENSIVE PATIENTS”
Authors: Latne Anup , Jirvankar Prabhakar
Published: October 2020

Hypertension is a major public health problem all over the world. The incidence of hypertension is increasing year after year and the prevalence of hypertension is increasing day by day due to increased life expectancy and aging population and their sedentary lifestyle. Hypertension is known to cause microvascular changes and increased cardiovascular risk from it. Microalbuminuria possibly reflects a state of increased renal endothelial permeability and is an easily measured marker of rather diffuse endothelial dysfunction, low grade inflammation and vascular disease burden2. Microalbuminuria has been determined as an important prognostic indicator and has been reported to be associated with increased cardiovascular risk and progressive renal damage. Reliable data on the prevalence of microalbuminuria in the general population and its association with cardiovascular risk factors is limited. Till now, there is little data available regarding screening and early treatment of hypertensive patients with microalbuminuria, as in the case of microalbuminuric non diabetic subjects. With these perspective this cross sectional study of microalbuminuria in non-diabetic hypertensive patients was undertaken to study prevalence of microalbuminuria in Non Diabetic hypertensive patients.
Objectives: To determine the prevalence of microalbuminuria in non-diabetic hypertensive patients and to correlate the presence of microalbuminuria with the patients of different clinical profiles.
Materials and Methods: This was observational, cross sectional study of Patients diagnosed with hypertension either admitted in ward or attending OPD of Medical College and Tertiary Care Centre. Urine microalbumin creatinine ratio was used for estimation of microalbuminuria.
Conclusion: It was proved that microalbuminuria prevalence was directly proportional to the duration of hypertension, the stage of hypertension. Prevalence of microalbuminria was low in ACE inhibitor and ARB treated hypertensive patients.

Published: October 2020

While some engineering fields have benefited from systematic design optimization studies, wave energy converters have yet to successfully incorporate such analyses into practical engineering workflows. The current iterative approach to wave energy converter design leads to suboptimal solutions. This short paper presents an open-source MATLAB toolbox for performing design optimization studies on wave energy converters where power take-off behavior and realistic constraints can be easily included. This tool incorporates an adaptable control co-design approach, in that a constrained optimal controller is used to simulate device dynamics and populate an arbitrary objective function of the user's choosing. A brief explanation of the tool's structure and underlying theory is presented. In order to demonstrate the capabilities of the tool, verify its functionality, and begin to explore some basic wave energy converter design relationships, three conceptual case studies are presented. In particular, the importance of considering (and constraining) the magnitudes of device motion and forces is shown.

Authors: YALÇIN Emre Deniz , ÇANAKÇI Aykut
Published: October 2020

In this research paper, dry sliding (unlubricated), corrosion and abrasive wear behavior of ZA27/ Graphene/ B4C hybrid nanocomposites were studied. The hybrid nanocomposite samples were fabricated by powder metallurgy technique. Tribological tests were performed by employing a ball-on-disc type in the unlubricated situation and different loads (1, 2, 5 and 10 N). The examination of the worn and corroded surfaces, the powder characterization was performed using scanning electron microscopy (SEM). The findings indicated that the increase in B4C nano-particle content can positively effect on the corrosion and wear behavior of the hybrid nanocomposites. The electrochemical polarization measurements showed that increasing of the nano B4C content causes high corrosion resistance in the hybrid nanocomposites. The corrosion tests showed that the corrosion rate value of the ZA27/Graphene/B4C hybrid nanocomposites decreased from 59.02 mpy to 16.77 mpy with increasing the nano B4C content from 0.25% to 2%.
HEAT TREATMENT EFFECT ON INTERFACE MICROSTRUCTURE AND HARDNESS OF A MEDIUM CARBON STEEL CLADDED BY AISI 316 STAINLESS STEEL
Authors: Di Schino Andrea
Published: October 2020

This paper focuses on carbon steel/stainless steel clad plate properties. The cladding was performed by submerged arc welding (SAW) overlay process. Following chemical element diffusion a  diffusion layer is formed between stainless steel and carbon steel interface of the cladded plate. Some hardness peaks were detected in the micro-alloyed steel close to the molten interface line in the coarse grained heat affected zone (CGHAZ). Results show that a stress relieving treatment is not sufficient to avoid hardness peaks. On the other hand, the hardness peaks in the CGHAZ of the micro-alloyed steel disappeared after quenching and tempering (Q&T).

Authors: AJAYI Olaoluwa Oluwafunto
Published: October 2020

The response of Bambara groundnut to co-inoculation with Abuscular mychorrhizal fungi (G. mossea) and Bradhyrhizobium japonicum (strain USDA110) with regard to leaf chlorophyll, percentage shoot nitrogen and phosphorus, nodule weight and plant biomass was studied. Bambara plants were grown under screen house conditions in pots. Plants were inoculated with 1ml of B. japonicum USDA 110 strain (109 cfu /ml), Mychorrizal was applied to the plants 10g, and 20g (90 spores/g) and water was applied at 10ml, 20 ml and 50ml every other day. The obtained results showed that dual inoculation activity was able to improve both nitrogen and phosphorus in plant shoot, MIE, but did not improve biomass and leaf chlorophyll when compared with plants subjected to single inoculation with only G. mossea and only B. japonicum. More Nitrogen and Phosphorus was retained in the shoot of plants co-inoculated with B. japonicum and 20g G. mossea when given 50ml of water and also had higher biomass. Leaf chlorophyll reduced in plants as flowering approached. B. japonicum was able to positively inﬂuence and establish symbiosis with G.mossea and synergistically effectively act as “mycorrhiza helper bacteria” (MHB) when both were co-inoculated in Bambara plant.

Authors: Ma'mun Abdul Rahman , Kosandi Meidi
Published: October 2020

Tulisan ini membahas politik pendanaan kampanye pada pemilihan presiden (Pilpres) 2019 dengan fokus pada dimensi penerimaan sumbangan dana kampanye yang besar dari kalangan oligark kepada pasangan Calon Presiden dan Calon Wakil Presiden Jokowi-Ma’ruf dan Prabowo-Sandi, dan dimensi pembayaran kembali pada saat pascapilpres kepada penyumbang dan pemilih. Dalam kaitan tersebut tulisan ini juga mendiskusikan pola pendanaan kampanye Jokowi-Ma’ruf sebagai pemenang Pilpres 2019, yang memengaruhi perubahan bentuk struktur politik oligarkis yang dihasilkan dari Pilpres 2019. Analisis tulisan ini didasarkan pada teori Oligarki dari Jeffrey A. Winters yang didukung oleh konsep pendanaan kampanye dari USAID dengan mengandalkan pada data sekunder laporan dana kampanye Jokowi-Ma’ruf dan Prabowo-Sandi yang dilaporkan ke KPU dan telah diaudit oleh kantor akuntan publik. Argumen yang ditawarkan adalah bahwa politik pendanaan kampanye pasangan Jokowi-Ma’ruf, sebagai pemenang Pilpres 2019, yang melibatkan para penyumbang besar dari kalangan oligark, memengaruhi perubahan sifat politik oligarkis pemerintahan hasil pilpres, yaitu perubahan sifat keterlibatan oligark dalam pemaksaan dan kekuasaan dari yang ‘terpecah’ menjadi ‘kolektif’, dan perubahan dari yang bersaing ‘liar’ antar-oligark menjadi ‘lunak’ bekerjasama dalam pemerintahan.

Published: October 2020

Introduction: Prevention is an important strategy to reduce the incidence of Exertional heat-related illnesses (EHRI) during training. It comprises a group of symptoms that occur in response to heat accumulation in the body caused by exercise or work in a hot and humid environment for a long period of time until the body is unable to regulate its temperature. The aim of the study is to find out associated risk factors and factors contributing EHRI especially in recruits of Nepal Army.

Methods: A case-control study was conducted in  recruit training center of Nepal army from June to September of 2017 using a Semi- structured questionnaire after taking ethical approval from IRB. All EHRI cases were included during data collection. The risk factors were analyzed with controls from the same center. 36 cases and 84 controls were taken. We computed the odd ratio (OR), corresponding 95% confidence interval (95% CI), Chi-Square test and Binary Logistic Regression test with SPSS version 20 software.

Results: 85% were wearing army uniform with camouflage vest during the exertional phase of training which was identified as noticeable risk factor with odd ratio (OR) of 13.26 with 95% CI: 5.05 – 34.84 in comparisons to controls. Fear from instructors and seniors in following rules were the protective factors for EHRI (P<0.05).

Conclusions: Wearing camouflouge vests and previous history of EHRI were significant risk factors associated with EHRI during training period. Proper clothing protocol and identifying vulnerable groups by the commanders and trainees may prevent EHRI in future.

Published: October 2020

Introduction: Subarachnoid block is commonly employed technique for lower abdominal and lower limb procedures. Bupivacaine and ropivacaine are commonly used local anesthetics for subarachnoid block. The aim of this study is to compare the efficacy and safety of isobaric Ropivacaine over hyperbaric Bupivacaine.

Methods: This was a prospective comparative study for a duration of six months. 60 ASA grade I-II adult patients between 16-60 years undergoing lower limb surgery under spinal anesthesia were randomized into two groups. Group I including patients who received 15 mg of hyperbaric bupivacaine 0.5% and group II including patients who received 22.5 mg of isobaric ropivacaine 0.75%. The onset and duration of sensory and motor block and hemodynamics including heart rate (HR), non invasive mean arterial blood pressure (MAP) and respiratory depression were recorded. Data were entered in Microsoft excel and statistical analysis was done by chi square test and T test using SPSS (version 23.0).

Results: Both the groups were demographically statistically insignificant. Successful block was attained in all patients in both groups. The sensory onset and motor onset were significantly delayed in the Ropivacaine Group compared to the Bupivacaine Group P<0.001. There was no significant difference in the hemodynamics (heart rate and mean arterial pressure ).

Conclusions: Though isobaric ropivacaine provided lesser degree of sensory and motor block with delayed onset compared to hyperbaric bupivacaine, it can effectively and safely used in subarachnoid block in lower limb surgeries without any major hemodynamic changes and adverse effects.

Authors: Acharya Jenash , Dixit Sanjaya Mani , Ghimire Samir
Published: October 2020

Introduction: Self-medication signifies using drugs that have not been prescribed, recommended or controlled by a licensed health professional. At present self medication is reportedly a global issue and the practice is predominant in developing and under-developed countries. The main aim of this study is to try and uncover the attitude and practice of students in a medical school located inside Kathmandu valley towards prescription and self-medication

Methods: A total of 104 students currently studying in one of the medical schools located inside Kathmandu Valley was provided a informed implied and verbal consent to participate in the study. All students were given a pre-validated, semi-structured questionnaire inside a lecture hall in their free hours between lectures. The data was analyzed and chi square test was done (p value<0.05) to see the association between medical students and their mind-set towards self medication.

Results: Among the total respondents, 80.8% thought that self medication was a part of self-care and 89.4% planned to continue self medication, 47.1% of them reported that they would advise their friends to stop practicing self medication, 70% reported having a registered medical practitioner with permission to prescribe medicines within 5-9 minutes walking distance from their abode, whereas around 1% reported that they self medicated so that they would not disturb the practioners. From the total, 6.7% presented with some side effects and had to visit the hospital

Conclusions: High incidence of self medication among undergraduate medical students might be able to sense false entitlement of almost being a doctor with authority to prescribe soon.
Safety Factor for Drilled Shaft Foundations Subjected to Wind-Induced Torsion
Authors: Aguilar Victor
Published: October 2020

Public transportation agencies commonly use drilled shaft foundations as support of mast arm traffic signs and signal pole structures. These structures and their foundations are subjected to wind-induced torsion. Design provisions can be found in AASHTO specifications for structural supports for highway signs, luminaires and traffic signals; nevertheless, those standards do not provide guidance to estimate the torsional resistance of drilled shaft foundations, or what an appropriate factor of safety (or resistance factor) for design could be. Although load and resistance factors format is desired because AASHTO is moving in that direction, still many Departments of Transportation design requirements are based on factors of safety. In this study, a probabilistic approach is used to recommend a rational procedure to determine factors of safety that consider the uncertainties and the consequences of failure. This procedure can be modified for load and resistance factors design calibration, as well. The skin friction approach was calibrated employing reliability analysis, available statistics, published experimental data, and simulations. However, a lack of field test data has been noticed. Factors of safety for cohesive, cohesionless, and layered soils are recommended. They are presented as a function of the target reliability index, and which in-situ test is performed to obtain the soil strength properties. Three alternatives were considered: standard penetration test, cone penetration test, and vane shear test. The procedure described can be used by practitioners to select appropriate factors of safety based on local conditions when statistical parameters from a particular site investigation are available.
Development of Experimental P-Y Curves From Centrifuge Tests for Piles Subjected to Static Loading and Liquefaction-Induced Lateral Spreading
Authors: Souri Milad
Published: October 2020

The results of five centrifuge models were used to evaluate the response of pile-supported wharves subjected to inertial and liquefaction-induced lateral spreading loads. The centrifuge models contained pile groups that were embedded in rockfill dikes over layers of loose to dense sand and were shaken by a series of ground motions. The p-y curves were back-calculated for both dynamic and static loading from centrifuge data and were compared against commonly used American Petroleum Institute p-y relationships. It was found that liquefaction in loose sand resulted in a significant reduction in ultimate soil resistance. It was also found that incorporating p-multipliers that are proportional to the pore water pressure ratio in granular materials is adequate for estimating pile demands in pseudo-static analysis. The unique contribution of this study is that the piles in these tests were subjected to combined effects of inertial loads from the superstructure and kinematic loads from liquefaction-induced lateral spreading.

Every person needs to use critical thinking, therefore, it is important to develop students' critical thinking in all classes including Physics. We summarize various definitions of critical thinking and we describe the survey, where students solve problems whose solution requires critical thinking. We compare students' results to see if they can solve problems without physics content with better successfulness than the problems with physics content and to see how the school attendance impacts its development.
Educational Digital Media Tools to Reformulate Activity and Object in Indigenous Science and Environmental Education
Authors: Morales Reynaldo A.
Published: October 2020

This paper examines the functioning of and underlying assumptions about digital media in collaborative curriculum design processes in public science and environmental education, and community-designed action research learning programs. The article discusses teaching practices in US rural Northeast Wisconsin among Native Youth learning processes, from the complementation and articulation of formal and informal education to meaningful engagement and participation in science. The focus on the transformative use of digital media in science community education is intended to serve two interrelated purposes: First, it helps to address cultural-historical relations around the production of knowledge and relevant curriculums and pedagogies for rural tribal youth. Second, it intersects with the opportunities for the transferability of activity systems and action research centered around the production of mediational artifacts designed for the collective negotiation between First Nations Tribal communities and western modeled schools, institutions, workplaces, and societal roles. The transferability of this model envisions the incorporation of local actors and institutions in a deep artifact-based dialogue around epistemologies of self-determination and sustainability for Peoples who are fighting for their survival. These propositions take a new level when the transformative power of digital media shifts representations of power in historically marginalized communities, serving a larger activity of reorganizing ecologies of learning in education for culturally distinctive communities of practice.

FEATURES OF SUBJECTIVE REGULATION OF THE INVESTIGATOR'S ACTIVITIES DEPENDING ON ITS COMPLEXITY
Authors: Литвинова Марина Александровна
Published: October 2020

В статье обосновывается концепция сложности деятельности следователя органов внутренних дел, которая обуславливается уровнем сложности уголовного дела, критериями которой выступают показатели темпоральности и процессуальной неопределенности. Дается характеристика понятиям «темпоральность» и «процессуальная неопределенность» в дискурсе расследования уголовного дела. Автор приходит к выводу, что увеличение сложности деятельности следователей, то есть появление в ней сравнительно широкого спектра проблем, затруднений и неопределенностей, приводит к возрастанию сложности функций психической регуляции. Каждая из функций когнитивного, аффективного, регулятивного, коммуникативного или конативного характера актуализируются в процессе расследования сложных уголовных дел. При написании статьи автором использован собственный опыт следственной практики по расследованию уголовных дел и данные проведенного исследования субъективного мнения следователей органов внутренних дел, осуществляющих деятельность на территории Республики Карелии, о критериях сложности расследования уголовного дела. Автором предложено в теоретическом дискурсе классифицировать сложность деятельности следователя на три уровня: простой, сложный и особо сложный, которые определяются рядом характеристик расследования уголовного дела.

The article establishes the concept of complexity of the activity of the investigator of internal affairs bodies, which is determined by the level of complexity of the criminal case, the criteria of which are indicators of temporality and procedural uncertainty. The article describes the concepts of «temporality» and «procedural uncertainty» in the discourse of criminal investigation. The author comes to the conclusion that the increase in the complexity of the investigators ' activities, i.e. the appearance of a relatively wide range of problems, ambiguities, difficulties and uncertainties leads to an increase in the complexity of the functions of mental regulation. Each of the functions of a cognitive, affective, regulatory, communicative or conative nature is updated in the process of investigating complex criminal cases. When writing the article, the author uses his own experience of investigative practice in criminal cases and data from the study of the subjective opinion of investigators of internal Affairs bodies operating in the Republic of Karelia on the criteria for the complexity of criminal investigation. The author proposes to classify the complexity of the investigator's activity into three levels: simple, complex and particularly complex, which are determined by a number of characteristics of the criminal investigation.

Authors: Selvanayagam Stephen , Kang Amy , Ha David
Published: October 2020

Baloxavir is a newly approved, single-dose, oral influenza antiviral indicated for acute uncomplicated influenza in patients 12 years and older if symptomatic for less than 48 hours. The purpose of this article is to review currently available literature on the mechanism of action, pharmacokinetics, safety, and clinical and virologic efficacy of baloxavir. Its novel mechanism of action prevents influenza replication by targeting the viral cap-dependent endonuclease enzyme. In clinical trials baloxavir was shown to be superior to placebo and comparable to oseltamivir with regard to time to alleviation of symptoms and viral titer reduction and was well tolerated with minimal adverse effects. Baloxavir is a viable treatment option for acute uncomplicated influenza in certain age groups.

The brain tumors are among the common deadly illness that requires early, reliable detection techniques, current identification, and imaging methods that depend on the decisions of neuro-specialists and radiologists who can make possible human error. This takes time to manually identify a brain tumor. This work aims to design an intelligent model capable of diagnosing and predicting the severity of magnetic resonance imaging (MRI) brain tumors to make an accurate decision. The main contribution is achieved by adopting a new multiclass classifier approach based on a collected real database with new proposed features that reflect the precise situation of the disease. In this work, two artificial neural networks (ANNs) methods namely, Feed Forward Back Propagation neural network (FFBPNN) and support vector machine (SVM), used to expectations the level of brain tumors. The results show that the prediction result by the (FFBPN) network will be better than the other method in time record to reach an automatic classification with classification accuracy was 97% for 3-class which is considered excellent accuracy. The software simulation and results of this work have been implemented via MATLAB (R2012b).

Published: October 2020

El absceso hepático es un reto diagnóstico y terapéutico. Es una patología poco frecuente en la niñez que predomina en países en desarrollo y se asocia a malnutrición y parasitosis. El absceso hepático piógeno es el más frecuente, es una causa de hospitalización prolongada por el requerimiento de antimicrobianos endovenosos; usualmente con baja mortalidad.A continuación, presentamos una serie de cuatro casos clínicos de pacientes con abscesos hepáticos piógenos que fueron manejados entre el 2016 y 2018 en el Hospital de Especialidades Pediátricas.Tres pacientes fueron del sexo femenino y uno masculino. En dos de los pacientes se identi có factor predisponente: diabetes mellitus e infección avanzada por VIH. Los síntomas más frecuentes fueron ebre (100%), dolor abdominal (100%) y hepatomegalia (50%). En ninguno de los casos se sospechó absceso hepático a su ingreso. Los casos fueron diagnosticados por sonograma hepático y corroborados con tomografía abdominal. El tamaño promedio de las lesiones fue de 6.88 x 6.18 x 6.12 cm. Tres fueron de localización derecha y uno de localización izquierda. Todos los pacientes recibieron antibioticoterapia de amplio espectro y drenaje percutáneo. Se identi có agente etiológico en uno de los pacientes: Staphylococcus aureus.Los pacientes recibieron una media de 33 + 3.5 días de tratamiento. Con evolución favorable en todos los casos y mejoría en seguimiento con ultrasonidos. Ningún paciente requirió intervención quirúrgica. Abstract The liver abscess involves an authentic diagnostic and therapeutic challenge. It is not frecuent in childhood. Occurs mainly in developing countries and is associated to malnutrition and parasitic infection, that are described as risk factors. Pyogenic liver abscess represents, in most of the cases, a cause of long-time hospitalizations because of the requirement of endovenous treatment, but usually with low mortality.We describe a four-case series of patients with pyogenic liver abscess between 2016 and 2018 in Hospital de Especialidades Pediatricas in Panamá City.Three patients were female and one was a male. In two of the cases, there were risk factors such as diabetes mellitus and advanced HIV infection.The most frequent symptoms were: fever (100%), abdominal pain (100%) and hepatomegaly (50%).In neither one of the cases, liver abscess was suspected as diagnosis. All cases were diagnosed by hepatic sonogram and con rmed by abdominal CT- scan. The mean size of lesions was 6.88 x 6.18 x 6.12 cm. Three of the cases were located in right lobe and one in the left lobe of the liver. They were managed with broad-spectrum antibiotics and percutaneous drainage.Staphylococcus aureus was isolated in one case.The patients received a mean of 33 + 3.5 days of treatment. All cases evolved well with improvement of lesion in ultrasonography. None of the patients required surgical intervention.

¿Por qué algunos adultos miran atrás en sus años de infancia y encuentran afecto, mientrasotros, ansiedad y dificultades? Es bien conocido en salud mental, el resultado negativoque los eventos adversos experimentados en la niñez introducen en la vida del serhumano. La depresión, el trastorno de uso de alcohol y drogas, el pensamiento y comportamientosuicida, todos tienen raíces en aquel escenario de muchos actos. ¿Cuánto detodo este resultado pasa desapercibido por los padres y los maestros?Al menos, en un estudio llevado a cabo en agosto de 2019 por C.S. Mott Children’s Hospital1, entre 819 padres de familia, para un 40% de los padres resulta difícil reconocer ladepresión en sus hijos, un 30% lo atribuyen a que los hijos lo saben ocultar muy bien, un14% acepta que entre ellos, padres e hijos, se conversa poco o se está poco tiempo juntos,dice un 7% de los padres. Interesante que solo un 4% refiere desconocer los signosde depresión que hay que buscar.
