Authors: Мельничук Н. І. , Шабат Г. І. , Чурпій І. К.
Published: October 2019

Резюме. На сьогоднішній день, колоректальний рак залишається одним з найважливіших в клінічній онкології, тому що є другим за летальністю серед онкологічної патології в cвіті (1 з 3 осіб, в яких діагностовано колоректальний рак помирають від цього захворювання). В Україні колоректальний рак знаходиться на четвертому місці серед причин смертності від онкологічної патології в чоловіків, та на третьому – у жінок.

В статті коротко розглянуто фактори ризику, скринінгові методи колоректального раку, економічну ефективність та шляхи впровадження скринінгової програми. Завдяки скринінгу колоректального раку можна виявляти премалігнізовані утворення та виявляти рак на ранній стадії, що дозволяє проводити своєчасне та високоякісне лікування, а також знижувати смертність від даного захворювання.

Оскільки Україна входить в групу країн із низьким та середнім рівнем доходу, то впровадження ефективної скринінгової програми для КРР зустрічає ряд перешкод. В більшості високорозвинених країн Світу скринінг КРР розпочинається у віці 45 – 50 років, але в осіб з підвищеним ризиком скринінг розпочинається раніше.

Всі скринінгові програми крім покращення якості та збільшення тривалості життя пацієнтів є ще і економічно ефективними порівнюючи із ситуацією відсутності скринінгу.

Скринінг найкраще впроваджувати шляхом розробки системи ідентифікації прицільної когорти пацієнтів, яким потрібен скринінг (включаючи фактори ризику), проводити регулярне оновлення інформації, та навігацію тих пацієнтів, в яких виявлено позитивні результати обстеження в послідуючому процесі лікування та спостереження.

В статті надано аналіз ефективності трьох скринінгових методик колоректального раку  для пацієнтів із помірним ризиком розвитку раку у віці від 50 до 75 років.

Authors: Smit Eline Suzanne , Zeidler Chamoetal , Resnicow Ken , de Vries Hein
Published: October 2019

Background

The effectiveness of digital health communication may be increased by enhancing autonomy supportiveness.

Objective

This study aimed to identify the most autonomy-supportive message frame within an intervention for increasing vegetable intake by testing the effect of the following 2 strategies: (1) using autonomy-supportive language and (2) providing choice.

Methods

A Web-based 2 (autonomy-supportive vs controlling language)×2 (choice vs no choice) experiment was conducted among 526 participants, recruited via a research panel. The main outcome measures were perceived autonomy support (measured using the Virtual Care Climate Questionnaire, answered with scores 1 to 5), perceived relevance (measured with one question, answered with scores 1 to 5), and overall evaluation of the intervention (measured with 1 open-ended question, answered with scores 1 to 10).

Results

Choice had a significant positive effect on the overall evaluation of the intervention (b=.12; P=.003), whereas for participants with a high need for autonomy, there was a significant positive effect on perceived relevance (b=.13; P=.02). The positive effect of choice on perceived autonomy support approached significance (b=.07; P=.07). No significant effects on any of the three outcomes were observed for language.

Conclusions

Results suggest that provision of choice rather than the use of autonomy-supportive language can be an easy-to-implement strategy to increase the effectiveness of digital forms of health communication, especially for people with a high need for autonomy.
Quality of Deaf and Hard-of-Hearing Mobile Apps: Evaluation Using the Mobile App Rating Scale (MARS) With Additional Criteria From a Content Expert
Authors: Romero Ryan Lee , Kates Frederick , Hart Mark , Ojeda Amanda , Meirom Itai , Hardy Stephen
Published: October 2019

Background

The spread of technology and dissemination of knowledge across the World Wide Web has prompted the development of apps for American Sign Language (ASL) translation, interpretation, and syntax recognition. There is limited literature regarding the quality, effectiveness, and appropriateness of mobile health (mHealth) apps for the deaf and hard-of-hearing (DHOH) that pose to aid the DHOH in their everyday communication and activities. Other than the star-rating system with minimal comments regarding quality, the evaluation metrics used to rate mobile apps are commonly subjective.

Objective

This study aimed to evaluate the quality and effectiveness of DHOH apps using a standardized scale. In addition, it also aimed to identify content-specific criteria to improve the evaluation process by using a content expert, and to use the content expert to more accurately evaluate apps and features supporting the DHOH.

Methods

A list of potential apps for evaluation was generated after a preliminary screening for apps related to the DHOH. Inclusion and exclusion criteria were developed to refine the master list of apps. The study modified a standardized rating scale with additional content-specific criteria applicable to the DHOH population for app evaluation. This was accomplished by including a DHOH content expert in the design of content-specific criteria.

Results

The results indicate a clear distinction in Mobile App Rating Scale (MARS) scores among apps within the study’s three app categories: ASL translators (highest score=3.72), speech-to-text (highest score=3.6), and hard-of-hearing assistants (highest score=3.90). Of the 217 apps obtained from the search criteria, 21 apps met the inclusion and exclusion criteria. Furthermore, the limited consideration for measures specific to the target population along with a high app turnover rate suggests opportunities for improved app effectiveness and evaluation.

Conclusions

As more mHealth apps enter the market for the DHOH population, more criteria-based evaluation is needed to ensure the safety and appropriateness of the apps for the intended users. Evaluation of population-specific mHealth apps can benefit from content-specific measurement criteria developed by a content expert in the field.
Effects and Implementation of a Mindfulness and Relaxation App for Patients With Cancer: Mixed Methods Feasibility Study (Preprint)
Authors: Mikolasek Michael , Witt Claudia Margitta , Barth Jürgen
Published: October 2019

BACKGROUND

Cancer diagnosis and cancer treatment can cause high levels of distress, which is often not sufficiently addressed in standard medical care. Therefore, a variety of supportive nonpharmacological treatments have been suggested to reduce distress in patients with cancer. However, not all patients use these interventions because of limited access or lack of awareness. To overcome these barriers, mobile health may be a promising way to deliver the respective supportive treatments.

OBJECTIVE

The aim of this study is to evaluate the effects and implementation of a mindfulness and relaxation app intervention for patients with cancer as well as patients’ adherence to such an intervention.

METHODS

In this observational feasibility study with a mixed methods approach, patients with cancer were recruited through the web and through hospitals in Switzerland. All enrolled patients received access to a mindfulness and relaxation app. Patients completed self-reported outcomes (general health, health-related quality of life, anxiety, depression, distress, mindfulness, and fear of progression) at baseline and at weeks 4, 10, and 20. The frequency of app exercise usage was gathered directly through the app to assess the adherence of patients. In addition, we conducted interviews with 5 health professionals for their thoughts on the implementation of the app intervention in standard medical care. We analyzed patients’ self-reported outcomes using linear mixed models (LMMs) and qualitative data with content analysis.

RESULTS

A total of 100 patients with cancer (74 female) with a mean age of 53.2 years (SD 11.6) participated in the study, of which 25 patients used the app regularly until week 20. LMM analyses revealed improvements in anxiety (P=.04), distress (P<.001), fatigue (P=.01), sleep disturbance (P=.02), quality of life (P=.03), and mindfulness (P<.001) over the course of 20 weeks. Further LMM analyses revealed a larger improvement in distress (P<.001), a moderate improvement in anxiety (P=.001), and a larger improvement in depression (P=.03) in patients with high levels of symptoms at baseline in the respective domains. The interviews revealed that the health professionals perceived the app as a helpful addition to standard care. They also made suggestions for improvements, which could facilitate the implementation of and adherence to such an app.

CONCLUSIONS

This study indicates that a mindfulness and relaxation app for patients with cancer can be a feasible and effective way to deliver a self-care intervention, especially for highly distressed patients. Future studies should investigate if the appeal of the app can be increased with more content, and the effectiveness of such an intervention needs to be tested in a randomized controlled trial.

Published: October 2019

BACKGROUND

The clinical benefits of enhanced recovery programs (ERPs) have been extensively researched, but few studies have evaluated their cost-effectiveness. Our ERP for open liver resection is based closely on the guidelines produced by the Enhanced Recovery After Surgery Society (2016). This study follows on from a previous randomized controlled trial. We also undertook a long-term follow-up of the patients enrolled in the original trial alongside an analysis of the associated health economics.

OBJECTIVE

We aimed to undertake a health economic and long-term survival analysis as part of a trial investigating the implementation of an ERP for open liver resection.

METHODS

The enhanced recovery elements utilized included extra preoperative education, carbohydrate loading, oral nutritional supplements, postresection goal-directed fluid therapy (LiDCOrapid), early mobilization, and physiotherapy (twice a
day compared with once per day in the standard care group). A decision-analytic model was used to compare the study endpoints for ERP versus standard care provided to patients undergoing open liver resection. Outcomes obtained included costs per life-years gained. Resource use and costs were estimated from the perspective of the National Health Service of the United Kingdom. A decision tree and Markov model were constructed using results from our earlier trial and augmented by external data from other published clinical trials. Long-term follow-up was also undertaken for up to 5 years after the surgery, and data were analyzed to ascertain if the ERP conferred any benefit on long-term survival.

RESULTS

Patients receiving ERP had an average life expectancy of 6.9 years versus 6.1 years in the standard care group. The overall costs were £9538.279 (£1=US $1.60) for ERP and £14,793.05 for standard treatment. This results in a cost-effectiveness ratio of –£6748.33/QALY. Patients receiving ERP required fewer visits to their general practitioner (P=.006) and required lesser help at home with day-to-day activities (P=.04) than patients in the standard care group. Survival was significantly improved at 2 years at 91% (42/46) for patients receiving ERP versus 73% (33/45) for the standard care group (P=.03). There was no statistically significant difference at 5 years after the surgery.

CONCLUSIONS

ERPs for patients undergoing open liver resection can improve their medium-term survival and are cost-effective for both hospital and community settings.

Authors: Mubashir Muhammad , Fong Yeong Yin , Keong Lau Kok , Sharrif Mohd. Azmi Bin
Published: October 2019

CO2 capture technologies including absorption, adsorption, and cryogenic distillation are reported. Conventional technologies for CO2 separation from natural gas have several disadvantages including high cost, high maintenance, occupy more space and consume high energy. Thus, membrane technology is introduced to separate CO2 due to their several advantages over conventional separation techniques. Inorganic membranes exhibit high thermal stability, chemical stability, permeability and selectivity for CO2 and CH4 separation as compared to other type of membranes. Zeolite membranes are potential for CO2 separation due to their characteristics such as, well define the pore structure and molecular sieving property. Among the zeolite membranes, DDR membranes exhibit highest selectivity for CO2 and CH4 separation. DDR membranes are synthesized by conventional hydrothermal and secondary growth methods. These methods required very long synthesis duration (25 days) due to extremely low nucleation and crystal growth rate of DDR zeolite. In this review, synthesis and performance of DDR membrane in CO2 separation from CH4 reported by various researchers are discussed. Challenges and upcoming guidelines related to the synthesis DDR membrane and performance of DDR membrane also included.

Published: October 2019

Mechanical and morphological properties of acrylonitrile-butadiene-styrene (ABS)/zinc oxide (ZnO) nanocomposites used ethylene-vinyl acetate copolymer (EVA) as compatibilizer were investigated. The ABS/ZnO nanocomposites without and with EVA 4 wt% were prepared by melting-blend with an internal mixer. The results showed that the addition of ZnO nanoparticles did not improve the mechanical properties of ABS/ZnO nanocomposites. The impact strength of the ABS/ZnO nanocomposites decreased with increasing ZnO content. The addition of EVA in ABS showed a decrease the impact strength but increased after adding ZnO in ABS/EVA matrix. The ABS/ZnO nanocomposites with EVA was higher the percent strain at break, but lower Young’s modulus, tensile strength and impact strength than the neat ABS and ABS/ZnO nanocomposites. The percent strain at break of ABS/ZnO nanocomposites increased with incorporation of EVA all ZnO compositions. However, the poor compatibility between ethylene in EVA and ABS matrix reduced as most of the mechanical properties of ABS/EVA/ZnO nanocomposites. The ZnO particle distributions in nanocomposites were studied by scanning electron microscopy (SEM), which observed that ZnO particles agglomerated in ABS and ABS/EVA matrix. The fractured surfaces of impact test samples were also observed through SEM and revealed that the ductile fracture of ABS was converted to brittle fracture with addition of ZnO.

Authors: Rattan Gaurav , Prasad R.
Published: October 2019

In the present study four catalysts, prepared by four different methods i.e. co- impregnation, citric acid sol-gel, urea nitrate combustion and urea gelation co- precipitation methods, have been used to study the effect of CO oxidation. The precursor Cu(NO3) 23H2O has been used as for the preparation of catalysts having the composition CuCe5.17Zr3.83Ox/-Al2O3(25wt%). Catalysts were calcined at 5000C and characterized by BET, XRD, TGA/DSC and SEM. A fixed weight (100 mg) of the catalyst was taken in a tubular fixed bed reactor at atmospheric pressure. 2.0% CO in air at a total feed rate of 60 ml/min was used in the reactor. The oxidation of CO to carbon dioxide was carried out at temperature ambient to 280oC. The preparation methods effect the catalytic activity of the catalysts as is discussed in the results. Excellent activity for CO oxidation is shown by the catalyst prepared by sol – gel method followed by co-impregnation, urea gelation and urea nitrate combustion methods. It exhibited the total conversion at 210oC. All the four catalysts prepared did not show any deactivation activity for 50 hours of continuous runs.

Published: October 2019

Cutinase is a hydrolytic enzyme that has both properties of lipase and esterase, thus finding its use in many areas. Previous studies have investigated both upstream and downstream processes for cutinase production from microbial source. However, no study has yet to address the use of membrane chromatography for cutinase purification, which is more favourable in terms of process resolution and product throughput as compared to the conventional gel chromatography. Hydrophobic interaction was chosen as the separation mechanism for cutinase purification in this study. The optimisation of cutinase purification in two different types of chromatographic media; conventional packed-gel and membrane matrix, were pre-determined by the best compromise between the recovery and purity of the purified cutinase. It was found that the optimised condition were of pH 4.0 and 1.0 M ammonium sulfate for the conventional column (50% recovery, 4.8-fold purity) and pH 6.0 with 1.5 M ammonium sulfate for the membrane–matrix column(87% recovery, 30-fold purity). Preferential interaction analysis was used to describe the protein chromatographic behaviour in each chromatographic media. Graph of natural algorithm of protein retention data to the function of salt concentration at pH 4.0 and 6.0 for each column were plotted. It was found that at the optimum pH condition for gel-packed column, a small amount of ammonium sulfate was sufficient to achieve maximum cutinase recovery and purity since the effect of salt at that particular pH were less significant. Consequently, the number of released water molecules were calculated and it was observed that for membrane column, larger number of water was released at pH 6.0 illustrating more protein were bounded to the stationary phase, thus explaining the optimum pH condition of the particular column.

Authors: Nandari Wibiana W. , Prasetyo Imam , Fahrurrozi Moh.
Published: October 2019

Methane is a potential alternative energy source which is abundant and produces lower CO2 emissions when it is used as fuel due to the content of C in the methane molecule is much lesser than its H content. Besides in a form of gas, methane in nature can also be in the form of methane hydrates. The formation process of methane hydrates in nature can be adopted as a method of storage of methane. In this study, a thermodynamics review will be studied related to temperature and pressure in a phase equilibrium system of methane hydrate . Thermodynamic model aims to predict the stability of methane hydrates for effective storage of methane. Each volume of methane hydrate contains as 164 volumes of methane gas under standard conditions ( STP ). The study was conducted by adsorbing methane on a wet porous carbon with the method of static volumetric.. The experimental results show that at the temperature of 274 K methane hydrates was formed at a pressure of 2.75 MPa; at a temperature of 275 K, pressure of 3.16 MPa; at a temperature of 276 K, pressure of 3.44 MPa, while at a temperature of 277 K, pressure of 3.67 MPa. Temperatures and pressures data are used to calculate the parameters of Langmuir equation constants modeled by the Van der Waals - Platteeuw for the chemical potential of water in the hydrate phase, Holder et al for the chemical potential of water in the liquid phase, as well as for the Gibbs-Thomson effect of porous carbon media.
Influence of Water Content on Biofiltration Performance
Authors: Badilla Daisy B , Gostomski Peter A , Dalida Maria Lourdes P
Published: October 2019

In biofiltration, contaminants in a gas stream are transferred into a biofilm on the filter bed medium and are metabolized by the microorganisms. Water is essential for microbial growth/activity and for transport of nutrients. In both full-scale and laboratory-scale systems, the water content of the medium is difficult to control. In this study, a biofilter, with rigorous water content control and internal gas recycle, was used to determine the influence of the water content on the degradation of toluene. Soil was used as the medium for treating toluene-contaminated air at an average inlet concentration of 263 ppm and a flow rate of 21 ml min-1. Through a water retention curve, gravimetric water content was related to matric potential. Results showed that lowering the water content from 79 to 48% (dry weight) or -20 to -400 cm H2O matric potential decreased the elimination capacity (EC) by 42% (29.8 to 17.3 g m-3h-1). Wetting the medium by increasing the matric potential from -400 to -10 cm H2O increased the elimination capacity to 43.9 g m-3h-1. However, further increase of the matric potential from -10 to -5 cm H2O decreased the elimination capacity by 57% (43.9 to 19.0 g m-3 h-1). Thus, this study suggests the soil water content should be controlled at about 96% (dry weight) or a matric potential of -10 cm H2O and the maximum elimination capacity is restricted to a narrow water content/matric potential. This narrow range impacts on the operation of full-scale biofilters as traditional techniques for water content control would make maintaining this range difficult.

Published: October 2019

Untreated wastewater from textile industries when discharged to nearby waterways would cause considerable health concerns to humans and animal life and to the host environment. They contain various chemicals such as dyes, detergents and surfactants, some of which are recalcitrant to biodegradation. Such wastewater can be better remediated by chemical treatment. The treatment of a textile bleaching and dyeing industrial wastewater was done by Coagulation and Flocculation Method using a jar test apparatus. Alum, polyaluminum chloride (PAC), and ferrous sulfate were used in separate runs as coagulants, while excelfloc 264 (a polyacrylamide copolymer) was used as flocculant. Preliminary tests were first conducted to determine the appropriate coagulation and flocculation agitation rates and settling time. The initial pH of the sample effluent was varied from 5 to 8 for alum coagulation, 5 to 8.5 for PAC coagulation and 9 to 11 for ferrous sulfate coagulation. The dosages of each coagulant and the excelfloc were varied from 200 to 1000 ppm, and 0.5 to 2.5 ppm, respectively. Experimental results showed that the optimum initial pH of the wastewater using alum, PAC, and ferrous sulfate were 7, 7.5, and 10, respectively. The optimum dosages of the coagulants were found to be 600ppm for alum and 800ppm for both PAC, and ferrous sulfate. The optimum flocculant dosages were 1.5ppm with alum, 1 ppm with PAC and 2ppm with ferrous sulfate. The highest percentage removal of COD, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), chromium, and color were found to be 58.55%, 65%, 36.51%, 76.45%, and 78.96%, respectively, using alum: 65.4%, 67.5%, 35.84%, 44.92%, and 75.49%, respectively using PAC; and, 55.72%, 34.16%, 33.95%, 19.88%, and 48.56%, respectively, using ferrous sulfate. Among the three coagulants tried, coagulation with PAC gave the highest percentage of COD removal of 65.64% and TSS removal of 67.5% while alum gave the highest removal of both chromium and color at 76.45% and 94.49%, respectively. Rapid and slow agitation rates used were 240rpm for 1 minute and 40rpm for 20 minutes, respectively; while settling time was 30 minutes. Kinetics of the COD removal was studied at the optimum conditions. Kinetic model, determined by curve fitting with the coagulation/flocculation reaction, was observed to follow a first-order rate of reaction.

Published: October 2019

The activity enhancement of metal ion-exchange mesoporous silicate FSM-16 (MeFSM-16) by sulfiding with hydrogen sulfide was studied using acid-catalyzed reactions, isomerization of I-butene, cis-2-butene and cyclopropane, as model reactions. It was revealed that the catalytic activities of MeFSM-16 for the acid-catalyzed reactions were remarkably enhanced after sulfiding with hydrogen sulfide. Moreover, it was observed that the optimum enhancement effect of hydrogen sulfide was obtained at the sulfiding temperature of 200°C. Infrared spectroscopic measurement of pyridine adsorption over sulfided MeFSM-16 showed that the activity enhancement of MeFSM-16 resulted in the generation of new Bronsted acid sites. Keywords: Metal ion-exchange, mesoporous silicate, hydrogen sulfide, and activity enhancement.
Heavy Metals Characterization of Sludge from a Philippine Recycling Paper Mill
Authors: Carrillo Lorraine A. , Gallardo Susan M.
Published: October 2019

Wastewater treatment sludge, which is the largest volume residual waste stream generated by the pulp and paper industry, is generally disposed of in a dedicated landfill. Composting the sludge is an alternative method proposed by the Asian Regional Research Program on Environmental Technology-De La Salle University (ARRPET-DLSU) Minor Issue Group. The Philippine Department of Agriculture's (DA) standards for an organic fertilizer's maximum allowable content of heavy metals provided the legislative regulation for the conversion of sludge to compost. The research was designed to characterize the sludge samples from TIPCO, a Philippine paper-recycling mill, and establish whether the sludge contained the heavy metals cadmium, chromium, lead, mercury, nickel, and zinc using atomic absorption spectrophotometer (MS). Sampling was done for four weeks during newsprint and white paper production. Three discharge terminals were established as sampling points. The samples showed that the metal content of the sludge vary from point to point and was highest throughout the manufacture of white paper. Chromium, mercury, and nickel, however, were nondetectable in all the samples, while cadmium was detectable only in very few samples. Lead and zinc were present at all three points and were highest at the de inking sludge. Comparing the results with Part 503 of the United States EPA and the DA's guidelines for organic fertilizers yield significantly lower parameter values. Composting the sludge was, therefore, found to be a feasible option for recycling paper-mill sludge since the metal content were very low compared to local and international standards.

This research aimed to empirically examine the effect of parents’ social support on academic achievement through the mediation of intrinsic motivation to learn. It was hypothesized that parents’ social support positively affect academic achievement through the mediation of intrinsic motivation to learn. Researcher adapted Gordon’s Parent Subscale Social Support Questionnaire for Children Rahmi’s Parental Support Scale and Rahmi’s Intrinsic Motivation to Learn Subscale along with weighted summative asessment tests to measure academic achievement. Participants were 84 students of grade 8 from three different junior high schools in Yogyakarta. Path analysis was used to investigate the hyphotesis. Results indicated that parents’ social support was a significant predictor of intrinsic motivation to learn, b = 0.55, (p < 0.05), and that intrinsic motivation to learn was a significant predictor of academic achievement, b = 0.47, (p < 0.05). These results supported the mediational hypothesis. Parents’ social support was no longer a significant predictor of academic achievement after including the mediator, parents’ social support, b = 0.16, (p > 0.05), consistent with full mediation.

Adolescents are active social media user. There are various interactions  that happen in social media, social support is one of them. In Instagram, the interaction between users can be giving likes, comments, and sending direct messages. Meanwhile, high school adolescents (15—18 years old) have high preoccupation toward their body image. Thus, online social support is considered to have relationship with body image in adolescents Instagram’s user. The purpose of this research was to examine the relationship between online social support and adolescent’s body image. The subjects of this research were adolecents who lived in DI Yogyakarta, DKI Jakarta, Bandung, and Surabaya (n = 235). Body image was  measured using MBSRQ-AS (The Multidimensional Body-Self Relations Questionnaire-Appearance Scales) and online social support was measured using Social Support in Social Media Scale. The result of product moment analysis showed that online social support significantly correlated with adolescent’s body image (r = 0.261; p < 0.05).

Actores sociales y formación de agendas regionalistas en la Región del Bío Bío en Chile
Authors: Sanzana Calvet Martín , Ramírez Valdés Felipe
Published: October 2019

El objetivo de esta investigación es presentar un análisis sobre la participación de actores sociales regionales en los debates actuales acerca del proceso descentralizador en Chile. Con base en la literatura académica se elaboró una metodología de análisis documental y cualitativo de un diario regional, para indagar sobre la relación entre dichos actores y la formación de agendas en la Región del Bío Bío. Aunque los resultados están limitados por la representatividad del estudio, indican la preponderancia de los actores estatales en los debates económicos y las reformas legales, y la ausencia de movimientos sociales. La contribución significativa de esta investigación es su potencial para enriquecer los estudios de evaluación del proceso descentralizador chileno, en medios de comunicación constructores de opinión pública, relacionados con quienes tienen poder para establecer la jerarquía de temas y actores, e incluso su omisión. Se concluye que existe un debate elitista sobre la descentralización y una agenda marcada por una dinámica centralista, lo que cuestiona la solidez local de dicho proceso.
Fronteras más allá de las fronteras. Inspecciones fronterizas extraterritoriales, controles yuxtapuestos, preclearance y la supresión de la protección internacional
Authors: Acosta Penco María Teresa
Published: October 2019

En este trabajo nos referiremos, concretamente, a los preclearence estadounidenses y a sus homólogos en el contexto de la Unión Europea: los controles yuxtapuestos o pasos fronterizos comunes. En ambos casos la frontera es exportada, de manera que una persona puede experimentar actuaciones de control fronterizo, como las inspecciones fronterizas, estando todavía en el territorio de su propio país o en el itinerario hasta su destino. En algunos países este cambio de emplazamiento de la frontera no ha ido acompañado, sin embargo, de un correlativo cambio en el ámbito de aplicación de su normativa en materia de protección internacional. Ello provoca una importante merma del derecho de asilo que asiste a las personas que tratan de cruzar dichas fronteras “anticipadas”.
El pensamiento constitucionalista en el pluralismo jurídico. Un paradigma del siglo XXI en construcción y desarrollo en el Estado de Derecho ecuatoriano
Authors: Almache Soto Emilio José
Published: October 2019

Desde las últimas décadas del siglo XX el pluralismo jurídico ha cobrado relevancia por su incidencia en el escenario social. Desde la Filosofía del Derecho y la Sociología, aunque con orientaciones y posturas diversas entre sí, se ocupan en la definición de nuevos constructos teóricos, requeridos para abordar la esencia del pluralismo jurídico en el contexto actual, reevaluándolo y brindándole nuevas vertientes de análisis. El Estado ecuatoriano garantiza a los pueblos indígenas la conservación y el desarrollo de sus formas tradicionales de convivencia y organización social originarias como expresión de la interculturalidad. Elementos que han tenido una incidencia positiva en la protección constitucional al medio ambiente y su desarrollo normativo a partir de los textos constitucionales. 
La fuerza política plurinacional, una posible salida a la crisis política en Guatemala, 2017-2018
Authors: León Pérez Rafael
Published: October 2019

El objetivo del artículo consiste en analizar y reflexionar sobre la participación política de organizaciones indígenas y campesinas en Guatemala, durante la coyuntura actual que estalló en agosto de 2017; proceso que es parte de una crisis política en curso que comenzó en abril de 2015, con los casos de corrupción, dando paso a un nuevo ciclo de protestas y produciendo la caída del binomio presidencial. En este contexto, se pretende demostrar el surgimiento de una “fuerza política plurinacional”, que tiene su antecedente en un movimiento indígena y que está conformada por organizaciones, que tienen en común el planteamiento de la refundación estatal para salir de la crisis actual, mediante la constitución y construcción de una Asamblea Constituyente y un Estado, ambos de carácter plurinacional. Se podrá determinar el grado de conformación de esta fuerza política considerando la relación de fuerzas en la coyuntura actual, así como la historicidad, la acción colectiva y los medios-contenidos del repertorio de confrontación de las organizaciones.
Pelindungan Konsumen dalam Transaksi Dagang Melalui Sistem Elektronik (Consumer Protection in E-Commerce)
Authors: Rongiyati Sulasi
Published: October 2019

E-commerce in Indonesia is continuing to grow. As a transactions with a special characteristic which involves parties across many jurisdictions without having to be physically present, a form of legal protection is highly required for the consumers. Through the normative juridical research method, this paper examines consumer protection in trade transaction through electronic system (E-Commerce) and its dispute resolution. The result of the research show that the consumer protection cannot be maximally implemented because regulating it is still distributed in several laws and requesting implementing regulations. In addition, Law No. 8 of 1999 on Consumer Protection has not been able to extend consumer protection in the electronics’ trade transactions / e-commerce as a whole, especially in the common situation where parties have jurisdictional differences. Whereas in the case of consumer disputes, the parties can take the matter through litigation (on court) as well as non-litigation (off court), in accordance to the agreement agreed by the parties. Nevertheless, the alternative online dispute resolutions can be implemented in full. This research recommends that the Government shall immediately form a Government Regulation related on trade/commerce transactions through an electronic system and to regulate online dispute resolutions. AbstrakTransaksi dagang melalui sistem elektronik di Indonesia terus berkembang. Sebagai transaksi yang memiliki karakteristik khusus yang melibatkan para pihak lintas yuridiksi tanpa harus bertemu fisik, sangat diperlukan pelindungan hukum bagi konsumen. Melalui metode penelitian yuridis normatif, tulisan ini mengkaji pelindungan konsumen dalam transaksi dagang melalui sistem elektronik dan penyelesaian sengketanya. Hasil penelitian menunjukan pelindungan terhadap konsumen pada transaksi dagang melalui sistem elektronik belum dapat dilakukan secara optimal karena pengaturannya masih tersebar dalam beberapa Undang-Undang (UU) yang memerlukan peraturan pelaksanaan. Di samping itu UU No. 8 Tahun 1999 tentang Perlindungan Konsumen belum mampu menjangkau pelindungan konsumen dalam transaksi dagang secara elektronik secara keseluruhan, khususnya dalam hal para pihak memiliki perbedaan yurisdiksi. Sedangkan dalam hal sengketa konsumen, para pihak dapat menempuh jalur pengadilan maupun di luar pengadilan sesuai kesepakatan para pihak, namun alternatif penyelesaian sengketa secara online dapat dilaksanakan secara penuh. Penelitian ini menyarankan kepada pemerintah untuk segera membentuk Peraturan Pemerintah tentang transaksi dagang melalui sistem elektronik dan mengatur mengenai penyelesaian sengketa secara online.
