Authors: Gierusz Witold , Rybczak Monika
Published: June 2020

The article described two full multidimensional controllers applied to steer a real vessel named ‘Blue Lady’ that is used by the Foundation for Safety of Navigation and Environment Protection at its training and research facility loacted at Silm lake in Poland. Both controllers were based on different approaches, but finally gave similar results. The first part describes the object to be controlled which is a training ship used for training of navigators in various conditions, areas and manoeuvres. This is followed by a short description of the theory for both controllers, Robust and Linear Matrix Inequalities (LMI). Next real time trials are described, which are 3 different manouvers for low velocities, executed by both LMI and Robust contrllers. In these trials ‘Blue Lady’ velocities, silhouete trajectory ans wind data are recorded. Finally the quality of work for both controllers is collected in two tables.
A Null Space-Based Blind Source Separation for Fetal Electrocardiogram Signals
Authors: Taha Luay , Abdel-Raheem Esam
Published: June 2020

This paper presents a new non-invasive deterministic algorithm of extracting the fetal Electrocardiogram (FECG) signal based on a new null space idempotent transformation matrix (NSITM). The mixture matrix is used to compute the ITM. Then, the fetal ECG (FECG) and maternal ECG (MECG) signals are extracted from the null space of the ITM. Next, MECG and FECG peaks detection, control logic, and adaptive comb filter are used to remove the unwanted MECG component from the raw FECG signal, thus extracting a clean FECG signal. The visual results from Daisy and Physionet real databases indicate that the proposed algorithm is effective in extracting the FECG signal, which can be compared with principal component analysis (PCA), fast independent component analysis (FastICA), and parallel linear predictor (PLP) filter algorithms. Results from Physionet synthesized ECG data show considerable improvement in extraction performances over other algorithms used in this work, considering different additive signal-to-noise ratio (SNR) increasing from 0 dB to 12 dB, and considering different fetal-to-maternal SNR increasing from −30 dB to 0 dB. The FECG detection of the NSITM is evaluated using statistical measures and results show considerable improvement in the sensitivity (SE), the accuracy (ACC), and the positive predictive value (PPV), as compared with other algorithms. The study demonstrated that the NSITM is a feasible algorithm for FECG extraction.

Authors: M. Siqueira Jucilene , A. Paço Teresa , Machado da Silva José , C. Silvestre José
Published: June 2020

The Biot-Granier (Gbt) is a new thermal dissipation-based sap flow measurement methodology, comprising sensors, data management and automatic data processing. It relies on the conventional Granier (Gcv) methodology upgraded with a modified Granier sensor set, as well as on an algorithm to measure the absolute temperatures in the two observation points and perform the Biot number approach. The work described herein addresses the construction details of the Gbt sensors and the characterization of the overall performance of the Gbt method after comparison with a commercial sap flow sensor and independent data (i.e., volumetric water content, vapor pressure deficit and eddy covariance technique). Its performance was evaluated in three trials: potted olive trees in a greenhouse and two vineyards. The trial with olive trees in a greenhouse showed that the transpiration measures provided by the Gbt sensors showed better agreement with the gravimetric approach, compared to those provided by the Gcv sensors. These tended to overestimate sap flow rates as much as 4 times, while Gbt sensors overestimated gravimetric values 1.5 times. The adjustments based on the Biot equations obtained with Gbt sensors contribute to reduce the overestimates yielded by the conventional approach. On the other hand, the heating capacity of the Gbt sensor provided a minimum of around 7 °C and maximum about 9 °C, contrasting with a minimum around 6 °C and a maximum of 12 °C given by the Gcv sensors. The positioning of the temperature sensor on the tip of the sap flow needle proposed in the Gbt sensors, closer to the sap measurement spot, allow to capture sap induced temperature variations more accurately. This explains the higher resolution and sensitivity of the Gbt sensor. Overall, the alternative Biot approach showed a significant improvement in sap flow estimations, contributing to adjust the Granier sap flow index, a vulnerability of that methodology.

Authors: Lo Chang-Cheng , Lee Ching-Hung , Huang Wen-Cheng
Published: June 2020

This study aimed to propose a prognostic method based on a one-dimensional convolutional neural network (1-D CNN) with clustering loss by classification training. The 1-D CNN was trained by collecting the vibration signals of normal and malfunction data in hybrid loss function (i.e., classification loss in output and clustering loss in feature space). Subsequently, the obtained feature was adopted to estimate the status for prognosis. The open bearing dataset and established gear platform were utilized to validate the functionality and feasibility of the proposed model. Moreover, the experimental platform was used to simulate the gear mechanism of the semiconductor robot to conduct a practical experiment to verify the accuracy of the model estimation. The experimental results demonstrate the performance and effectiveness of the proposed method.
An Ultrasonic Rheometer to Measure Gas Absorption in Ionic Liquids: Design, Calibration and Testing
Authors: Schirru Michele , Adler Michael
Published: June 2020

The first goal of this study is to identify the ideal piezoelectric material for the manufacturing of rheological reflectance ultrasonic sensors. The second goal is to integrate the ultrasonic rheometer within a gas absorption reactor and to measure viscosity changes in an ionic liquid (IL) caused by gas absorption. To achieve the objectives, bismuth titanate, lead titanate, lead metaniobate and lead zirconate titanate materials in layer, tungsten bronze and perovskite structures were assembled on aluminum delay lines and tested under thermal cycling between room temperature and 150 °C. The results showed that lead metaniobate in tungsten bronze structure is the most suitable material for long time duration thermal cycling. Therefore, the ultrasonic rheometer was assembled using this material and installed in a pressurized reactor to test a reference IL at the operating conditions of 50 °C and at a pressure of 80 bar. The reference IL was saturated with nitrogen as well as hydrogen gas. Viscosity signals remained constant under the hydrogen atmosphere, while in nitrogen atmosphere the absorption of the gas lead to a rise in the value of viscosity.
A Theoretical and Empirical Investigation of Design Characteristics in a Pb(Zr,Ti)O3-Based Piezoelectric Accelerometer
Authors: Lee Min-Ku , Han Seung-Ho , Park Jin-Ju , Lee Gyoung-Ja
Published: June 2020

A theoretical and experimental study on the design-to-performance characteristics of a compression-mode Pb(Zr,Ti)O3-based piezoelectric accelerometer is presented. Using the metamodeling to approximate the relationship between the design variables and the performances, the constituent components were optimized so that the generated electric voltage, representing sensitivity, could be maximized at different set values of the resonant frequency (25–40 kHz). Four kinds of optimized designs were created and fabricated into the accelerometer modules for empirical validation. The accelerometer modules fabricated according to the optimized designs were highly reliable with a broad range of resonant frequency as well as sufficiently high values of charge sensitivity. The fixed (or mounted) resonant frequency was between 16.1–30.1 kHz based on the impedance measurement. The charge sensitivity decreased from 296.8 to 79.4 pC/g with an increase of the resonant frequency, showing an inverse relation with respect to the resonant frequency. The design-dependent behaviors of the sensitivity and resonant frequency were almost identical in both numerical analysis and experimental investigation. This work shows that the piezoelectric accelerometer can be selectively prepared with best outcomes according to the requirements for the sensitivity and resonant frequency, fundamentally associated with trade-off relation.

Published: June 2020

Fumaroles represent evidence of volcanic activity, emitting steam and volcanic gases at temperatures between 70 and 100 ∘ C . Due to the well-known advantages of thermoelectricity, such as reliability, reduced maintenance and scalability, the present paper studies the possibilities of thermoelectric generators, devices based on solid-state physics, to directly convert fumaroles heat into electricity due to the Seebeck effect. For this purpose, a thermoelectric generator composed of two bismuth-telluride thermoelectric modules and heat pipes as heat exchangers was installed, for the first time, at Teide volcano (Canary Islands, Spain), where fumaroles arise in the surface at 82 ∘ C . The installed thermoelectric generator has demonstrated the feasibility of the proposed solution, leading to a compact generator with no moving parts that produces a net generation between 0.32 and 0.33 W per module given a temperature difference between the heat reservoirs encompassed in the 69–86 ∘ C range. These results become interesting due to the possibilities of supplying power to the volcanic monitoring stations that measure the precursors of volcanic eruptions, making them completely autonomous. Nonetheless, in order to achieve this objective, corrosion prevention measures must be taken because the hydrogen sulfide contained in the fumaroles reacts with steam, forming sulfuric acid.
Fast and Reliable Alternative to Encoder-Based Measurements of Multiple 2-DOF Rotary-Linear Transformable Objects Using a Network of Image Sensors with Application to Table Football
Authors: Bošnak Matevž , Klančar Gregor
Published: June 2020

Simultaneous determination of linear and angular positions of rotating objects is a challenging task for traditional sensor applications and a very limited set of solutions is available. The paper presents a novel approach of replacing a set of traditional linear and rotational sensors by a small set of image sensors. While the camera’s angle of view can be a limiting factor in the tracking of multiple objects, the presented approach allows for a network of image sensors to extend the covered area. Furthermore, rich image data allows for the application of different data processing algorithms to effectively and accurately determine the object’s position. The proposed solution thus provides a set of smart visual encoders emulated by an image sensor or a network of image sensors for more demanding spatially distributed tasks. As a proof of concept, we present the results of the experiment in the target application, where a 1.6 MP image sensor was used to obtain sub-degree angular resolution at 600 rpm and thus exceeding the design parameters and requirements. The solution allows for a compact, cost-effective, and robust integration into the final product.

The scientific article describes the concept and essence of forensic support of criminal proceedings, defines the levels, directions and forms of its implementation. It is substantiated that forensic support is realized during the investigation and prevention of criminal offenses, as well as the judicial review of criminal proceedings (cases) using forensic means, methods, techniques according to certain levels, directions and forms. The levels of forensic support of criminal proceedings are distinguished, namely: local; regional; state; international. Considering the established system of forensics, according to which the development of theoretical foundations and practical recommendations of forensic support is based on the provisions of the general theory of forensic science, forensic techniques, tactics and methods, three main areas of forensic crime are defined: forensic. In this case, the general theory of forensic science is of methodological importance for the formation of their scientific foundations. According to the mentioned directions, the main forms of forensic support of criminal proceedings are distinguished: – in the direction of technical and forensic support: the use of technical means and methods of detecting, fixing, collecting, investigating the traces of crime, other forensically relevant information, including through the use of special knowledge, involving specialists in investigative (investigative) actions; fixing the course and results of investigative (investigative), court actions; maintaining criminal registration and forensic records systems; involvement of experts and carrying out of expertise; – in the direction of tactical and criminalistic support: improvement of existing and development of new tactical techniques and their complexes; formation of tactics of investigative (search) actions; – in the direction of methodological and forensic support: development of new methods of investigation of criminal offenses (according to the criminal law and forensic classification); formulating recommendations to increase the effectiveness of the method of investigation of certain types (groups) of criminal offenses. These levels, directions and forms of forensic support should be considered in the scientific and practical aspect, which consists in creating the scientific basis of the tools, methods and techniques used the formation of practical recommendations for their application. The unity of theory and practice ensures effective achievement of the set goals in the system of forensic support of criminal proceedings.
SOME FEATURES OF EVALUATION OF EXPERT CONCLUSION IN THE CIVIL PROCESS (COMPARISON OF FORENSIC PRACTICES OF THE REPUBLIC OF ARMENIA AND THE USA)
Authors: Voskanyan P. , Titanyan E.
Published: June 2020

An expert conclusion is evaluated according to the criteria of its relevance, admissibility and reliability. In the judicial practice of the RA the legality or validity of a conclusion, as well as the contradictions in the conclusions, are directly related to the need for the description of the methodology in the expert conclusion. Therefore, the question often arises about the judge’s actions in the light of the absence of a note on the methods used during the examination. This article also examines the question of the possibility of assessment of an expert conclusion as appropriate evidence in a situation where the expert testifies about the methods used in making up the conclusion, but does not make the corresponding note in the conclusion.

The authors of the article analyze some judicial precedents, which had an important influence on this issue in the judicial practices of the Republic of Armenia and the USA, and referred to different, sometimes conflicting positions of judges of the Court of Appeal.

Enhanced Bagging (eBagging): A Novel Approach for Ensemble Learning
Authors: Tuysuzoglu Goksu , Birant Derya
Published: June 2020

Bagging is one of the well-known ensemble learning methods, which combines several classifiers trained on different subsamples of the dataset. However, a drawback of bagging is its random selection, where the classification performance depends on chance to choose a suitable subset of training objects. This paper proposes a novel modified version of bagging, named enhanced Bagging (eBagging), which uses a new mechanism (error-based bootstrapping) when constructing training sets in order to cope with this problem. In the experimental setting, the proposed eBagging technique was tested on 33 well-known benchmark datasets and compared with both bagging, random forest and boosting techniques using well-known classification algorithms: Support Vector Machines (SVM), decision trees (C4.5), k-Nearest Neighbour (kNN) and Naive Bayes (NB). The results show that eBagging outperforms its counterparts by classifying the data points more accurately while reducing the training error
Query Authentication of Outsourced Spatial Database
Authors: Hong Jun , Wen Tao , Guo Quan
Published: June 2020

Outsourcing spatial database to a third party is becoming a common practice for more and more individuals and companies to save the cost of managing and maintaining database, where a data owner delegates its spatial data management tasks to a third party and grants it to provide query services. However, the third party is not full trusted. Thus, authentication information should be provided to the client for query authentication. In this paper, we introduce an efficient space authenticated data structure, called Verifiable Similarity Indexing tree (VSS-tree), to support authenticated spatial query. We build VSS-tree based on SS-tree which employs bounding sphere rather than bounding rectangle for region shape and extend it with authentication information. Based on VSS-tree, the third party finds query results and builds their corresponding verification object. The client performs query authentication using the verification object and the public key published. Finally, we evaluate the performance and validity of our algorithms, the experiment results show that VSS-tree can efficiently support spatial query and have better performance than Merkle R tree (MR-tree)
Multi Label Ranking Based on Positive Pairwise Correlations Among Labels
Authors: Alazaidah Raed , Ahmad Farzana , Mohsin Mohamad
Published: June 2020

Multi-Label Classification (MLC) is a general type of classification that has attracted many researchers in the last few years. Two common approaches are being used to solve the problem of MLC: Problem Transformation Methods (PTMs) and Algorithm Adaptation Methods (AAMs). This Paper is more interested in the first approach; since it is more general and applicable to any domain. In specific, this paper aims to meet two objectives. The first objective is to propose a new multi-label ranking algorithm based on the positive pairwise correlations among labels, while the second objective aims to propose new simple PTMs that are based on labels correlations, and not based on labels frequency as in conventional PTMs. Experiments showed that the proposed algorithm overcomes the existing methods and algorithms on all evaluation metrics that have been used in the experiments. Also, the proposed PTMs show a superior performance when compared with the existing PTMs

Authors: Estakhri Rasoul , Bartari Lachin , Ghojazadeh Morteza
Published: June 2020

Introduction: Spontaneous bacterial peritonitis (SBP) is an infectious ascitic fluid with an unknown intraabdominal source. Rapid diagnosis of infection can improve prognosis in cirrhotic patients. Objectives: We aim to determine the diagnostic value of serum procalcitonin (PCT) and C-reactive protein (CRP) in SBP. Patients and Methods: In this cross-sectional study, we included 120 cirrhotic patients with possible diagnosis of SBP asities. Serum and ascitic fluid samples were taken from the patient before initiating antibiotics. The ascitic fluid parameters, serum levels of CRP, PCT and white blood cells were measured and the diagnostic value of the CRP and PCT were evaluated. Results: Of 120 patients, 59.16% had confirmed SBP. PCT with a cutoff of 0.8 ng/mL and CRP with cutoff of 10.5 mg/L had a sensitivity of 90.91% and 86.11% and specificity of 91.5% and 81.25% respectively in diagnosing of SBP. Considering PCT above 0.8 ng/mL and CRP above 10.5 mg/L both, they had the sensitivity and specificity of 96.87% and 83.92% in detecting SBP in cirrhotic patients. Conclusion: Serum PCT and CRP levels could predict SBP in cirrhotic patients while PCT had the most sensitivity and specificity. Considering both parameters, the sensitivity will increase, but the specificity is decreasing. Both PCT and CRP levels could be used as a less invasive method compared to ascites fluid analysis in diagnosing SBP.

Introduction: Malignant bone tumors account for 6% of childhood malignancies. The peak incidence rate for bone cancer is in adolescents. Geographic and race differences in incidence rate of bone tumors are important for correct diagnosis and treatment. Objectives: This study aimed to investigate the demographic features of patients with malignant bone tumors and prognostic factors. Patients and Methods: In a retrospective study, records of all patients diagnosed and treated for malignant bone tumor from March 1996 to February 2014 were investigated. Data were collected using checklists and analyzed using SPSS software. Results: The most common type of bone tumor was Ewing sarcoma (73.7%) in patients who were over 10 years old (87.5%). Primary site of disease in most cases of osteosarcoma and Ewing sarcoma was distal femur (50% and 27.3%, respectively). Most common clinical manifestation was local pain and mass (88.5%). Regarding metastasis, 72.7% of osteosarcoma patients and 32.4% of Ewing sarcoma patients had metastasis. There was not statistically relationship between survival rate and gender, age group and stage of disease at diagnosis time. One, three and five-year survival rate was lower than the previous studies. Conclusion: The incidence of Ewing sarcoma is more then osteosarcoma in West Azerbaijan. In our study there were no statistically important differences in survival rates of patients with metastasis at diagnosis time and those without metastasis.

Published: June 2020

Introduction: Considering the important role of early detection of malnutrition in patients with cancer and its negative effects on the outcome, as well as the lack of any published article (to the best of our knowledge) about the dietary quality index in head and neck cancer patients treated with chemoradio therapy, we decided to evaluate the nutritional status and dietary quality index in these patients. Methods: In this study, thirty-seven volunteer patients with head and neck cancer were recruited. Nutritional status of the patients was evaluated by Mini Nutritional Assessment (MNA) questionnaire. Dietary diversity score, dietary variety score, and diet quality index–international were calculated to assess the dietary quality of the patients. Results: Our findings indicated that about half of the patients were well nourished and 48.6%were at the risk of malnutrition. We did not find any significant differences between variousdietary quality indices and nutritional status of the patients. However, a significant reverse correlation was observed between dietary quality indices and nutritional status of the patients. Conclusion: According to our findings, the evaluation of nutritional status and the prediction of the patients at higher risks of chemoradio therapy-induced adverse events, may have a major role in the prevention of treatment gaps.

Primary cancer metastasis to thyroid gland is rare. The most common metastatic tumors of the thyroid gland are from lung, breast and renal cell carcinoma. In this case report, a patient with breast cancer metastasized to the thyroid gland is presented. A 38-year-old female patient was diagnosed with breast cancer, and positron emission tomography-computed tomography (PET-CT) imaging for breast cancer staging revealed fluoro-2deoxy-D-glucose (FDG) uptake in the thyroid nodule. Fine needle aspiration biopsy (FNAB) of the nodule revealed atypia of undetermined significance (Bethesda III). After neoadjuvant chemotherapy, simultaneous breast conserving surgery and total thyroidectomy were performed. Immunohistochemical staining of the pathological specimens revealed breast cancer that had metastasized to the thyroid gland. Immunohistochemical methods helped distinguishing primary thyroid cancer from metastasis. Also, nodules that showed activity involvement were detected randomly in PET-CT, and had to be evaluated in terms of malignancy.

Published: June 2020

Introduction: The acute coronary events are one of the most common problems which are accounted to higher mortality and morbidity rate around the world. The underlying mechanism is related to occlusion, and the best therapy is to reopen the affected vessels. Many factors can influence the outcomes of percutaneous coronary intervention (PCI). Methods: This cross-sectional study was conducted on 845 cases with acute myocardial infarction (AMI) undergoing PCI for evaluation of the "No-Reflow" phenomenon who were referred to Shahid Madani hospital in 2018. All demographic, laboratory and angiographic studies were evaluated. The obtained data were recorded and analyzed by SPSS 21. Results: Among 845 patients with STEMI, the incidence of angiographic no-reflow was 28% (n = 245). The older cases with co-morbid diseases and cardiac-related risk factors were considered as vulnerable to no-reflow after PCI. The other parameters were partially decisive factors for the prediction of no-reflow and mortality rate, such as higher MPV and MPV to lymphocyte ratio. Conclusion: The coronary artery involvement is a troublesome event because of the established heart risk factors, and sometimes treating it with PCI could be complicated due to no-reflow. The simple predictors (i.e., MPV to lymphocyte ratio) could help us reduce morbidity and mortality.

Published: June 2020

Introduction: The present study was an attempt to evaluate the role of ultrasonography on decreasing the number of attempts, failed punctures, time needed to perform the procedure and patients’ pain. Methods: This study is a prospective case-control. Patients were divided in two groups randomly. A two-dimensional probe was used to localize intervertebral space in the ultrasound guidance (US group). In manual palpation (MP group) however, insertion level was determined using the standard technique by manual palpation. The number of attempts (needle insertion) required for a successful tap and successful/unsuccessful attempts were considered as the primary outcome measures. Results: Male patients with an average age of 44.08±15.83 years accounted for 60% (30 individuals) of the population. Success rate was 92% in the US group and 34% in the MP group (P<0.001). It took 79.64± 19.91 and 85.4±11.62 minutes to identify the proper location in US and MP groups respectively (P=0.21). In the first attempt, it took 6.33±0.95 and 6.87±0.7 minutes to collect cerebrospinal fluid (CSF) in US and MP groups respectively (P=0.02). Average time taken to localize the sites in two attempts were 8.28±2.44 and 13.17±3.32 in US and MP groups respectively (P<0.001). Average number of attempts made in the US and MP groups were 1.08±0.27 and 1.64±0.66 (P<0.001) respectively. Conclusion: Ultrasonography has reduced the time needed for locating puncture to collect CSF, pain management in patients, determining the number of attempts, and defining the risk of traumatic puncture. Moreover, this technique is characterized by a higher success rate. Using ultrasonography in obese patients and people with lumbar problems is more important.

Published: June 2020

Wasp stings occur frequently in developing countries and often lead to fatal outcomes due to the effects of wasp venom. Hemolysis and rhabdomyolysis often complicate wasp stings and result in acute kidney injury (AKI). We report a case of multiple wasp stings leading to AKI and multiple organ dysfunction syndrome (MODS) in a 9-year-old Indonesian girl. Kidney biopsy revealed acute tubular necrosis and acute interstitial nephritis. Despite delayed admission, she recovered in 33 days after 3 days of intravenous steroid administration, eight sessions of intermittent hemodialysis, and two sessions of plasma exchange (PE). Complete recovery of kidney function, indicated by normal diuresis, normal estimated glomerular filtration rate, and negative albuminuria, was reached within 12 weeks. This case showed that immediate admission following multiple wasp stings (particularly >10 stings) to initiate early dialysis is important to promptly remove toxins and preserve kidney function. The case also showed that PE can be beneficial in cases of hemolysis and rhabdomyolysis complicated by MODS.

The features of the modification of acid-soluble chitosan by carbonyl-containing compounds in solution and by the method of surface modification of molded materials are investigated. The dependence of the rheological properties of polysaccharide solutions on the structure of the hydrocarbon radical of the modifier is established. The formed films based on iminochitosans, obtained by the interaction of the polymer with aldehydes in a solution of acetic acid, have lower surface, hydrophobic, and strength characteristics compared to chitosan films. The possibility of biodegradation of the obtained materials, as well as the dependence of the mass loss of the samples on the HLB level, which can be used to create wound dressings with programmed degradation, is shown.

Published: June 2020

El artículo analiza la evolución de la casación civil desde una perspectiva histórica, a partir de su inicial recepción y adecuación en nuestro ordenamiento jurídico hasta su actual configuración. Del mismo modo, analiza su problemática y posibilidades de reforma sistémica e integral que racionalice la actividad de los órganos casacionales de la Corte Suprema de Justicia de la República, reduzca la carga procesal y se asegure la igualdad de las partes en el proceso, con el fin de que se dé cabal cumplimiento a los fines de la casación y se garantice el principio de predictibilidad de las resoluciones judiciales en el ámbito de la justicia civil.
Lo que los juristas no dicen. Normas no expresadas y despositivización
Authors: Barberis Mauro
Published: June 2020

Uno de los problemas más intrigantes de la reciente teoría del derecho está representado por las reglas implícitas y/o no expresadas. Sin embargo, el tema, propuesto por Riccardo Guastini en los años noventa del siglo pasado, incomoda a otros juristas y teóricos: de hecho, lo discuten casi solo los genoveses y sus amigos, como veremos. El artículo reconstruye la tematización del problema, estrechamente relacionado con otros típicos temas «genoveses», como son la distinción interpretación/construcción y el mismo concepto de marco de Kelsen. Aquí se distinguen, especialmente, las normas implícitas de las normas (totalmente) no expresadas, volviendo a definir las primeras como una variable dependiente de su aplicación judicial, y considerando las segundas como un elemento del proceso que llamo despositivización del derecho.
Violencia familiar, un paso al feminicidio
Authors: Contreras Cuzcano Jhonny Hans
Published: June 2020

Las sociedades como la nuestra actualmente se debaten en una crisis estructural de diversa índole, que afecta gravemente la convivencia pacífica. Uno de esos factores está dado por los casos de violencia familiar, los cuales a pesar de los esfuerzos de la comunidad internacional y del propio Estado peruano se incrementan geométricamente, y lo que es peor, ello no acaba allí, sino que casi todos estos casos de violencia doméstica terminan en «feminicidio». Estos hechos que determinan un vínculo unívoco entre la violencia familiar y el feminicidio requieren, además de leyes, un tratamiento integral y multidisciplinario de protección efectiva cuando se denuncia la violencia doméstica, como campañas y tratamiento de salud mental, así como reafirmar y potenciar a la familia en la crianza de los hijos en valores, complementándose ello con un trabajo formativo integral desde los primeros años en las escuelas públicas y privadas.

Representações de guerra nas pinturas rupestres da Serra da Capivara, Pi, Brasil
Authors: da Silva Belarmino Vanessa , Justamand Michel , Frechiani de Oliveira Gabriel
Published: June 2020

As primeiras pesquisas arqueológicas realizadas na área do Parque Nacional Serra da Capivara, sudeste do Piauí-Brasil, iniciaram-se na década de 70, conduzidas pela arqueóloga Niède Guidon, com o objetivo de contextualizar os sítios com grafismos rupestres, resultando em um ordenamento prévio hipotético para um reconhecimento das identidades culturais e cronologias. A definição classificatória de Tradição parte das semelhanças tipológicas que são encontradas entre os grafismos. Nas pesquisas, os grafismos rupestres são considerados como um meio de comunicação que seguem um código pré-estabelecido. O comportamento agressivo e violento pode ser identificado no registro arqueológico em aldeias destruídas, tais como esqueletos humanos com marcas de fraturas e na gestualidade representada nos grafismos rupestres. Nosso artigo se refere a uma pesquisa em andamento e tem por objetivo a identificação de padrões gráficos presentes nas cenas de guerra e, como objetivo específico, a identificação de elementos reconhecíveis, como antropomorfos, objetos de usos e outros possíveis atributos culturais. Parece-nos que entre os grupos primitivos, o comportamento agressivo e violento poderia ocorrer por diversas motivações, obedecendo a ritos culturais, conflitos entre grupos, ou ainda, a aquisição de recursos essenciais para a sobrevivência do grupo.

DAMPAK SOSIAL TEKNOLOGI KOMUNIKASI BARU: MEMIKIRKAN ULANG KONSEP COPYRIGHT DI INTERNET
Authors: Wahid Abdul
Published: June 2020

Permasalahan hak cipta terus melahirkan perdebatan cukup panjang sejak gagasan ini pertama kali dikenalkan pada abad 18. Beberapa aspek seperti diversitas budaya, penyebaran pengetahuan, fair use, kontrol dan monopoli karya, sampai durasi berlakunya hak cipta merupakan domain permasalahan yang masih diberdebatkan hingga saat ini. Aktivitas saling berbagi antar pengguna (peer to peer) di internet dinilai sebagai pelanggaran hak cipta. Padahal, aktivitas tersebut juga dilakukan dalam dunia nyata sebagai bentuk penggunaan wajar, sama seperti meminjamkan buku yang telah dibeli.  Jika kegiatan saling berbagi antar pengguna di internet ini didefinisikan sebagai pelanggaran hak cipta, maka sebenarnya di ranah media baru hukum bekerja secara lebih dalam; mengatur kebiasaan yang tidak diatur dalam kehidupan nyata. Melihat permasalahan tersebut, paper ini berusaha menganalisis dengan fokus spesifik: meninjau ulang konsep hak cipta dalam media baru. Tesis utama dari paper ini berusaha untuk mengkontekstualisasikan isu hak cipta sesuai dengan era perkembangan dan inovasi teknologi yang tak terelakkan. Untuk itu, beberapa hal akan dijabarkan; dampak sosial teknologi komunikasi, konteks sosial perkembangan internet, teknologi dan karya cipta, copyright, dan kritik terhadap copyright. Tinjauan kritis ini akan melahirkan gagasan alternatif mengenai konsep copy right ketika diterapkan dalam media baru.
