Published: December 2019

Este artículo explora las relaciones comerciales de Ecuador con China en el periodo 2010-2013, se centra en las líneas de crédito que el Ecuador ha obtenido para financiar sus proyectos. China es la segunda potencia después de Estados Unidos, el segundo consumidor de petróleo, el mayor exportador mundial y un país en busca de recursos naturales que hagan posible suplir su demanda interna. Ecuador por su parte es un país en vías de desarrollo que necesita financiamientos para realizar proyectos y utiliza como medio de garantía la materia prima que posee, el petróleo, para obtenerlos. El objetivo de la investigación es conocer el nivel de endeudamiento que el Ecuador tiene actualmente, además de determinar la existencia de beneficios para Ecuador. Se utiliza el estudio de las balanzas comerciales, las ventajas y desventajas de cada proyecto, y las condiciones de los préstamos como métodos para obtener resultados. Las relaciones comerciales de Ecuador con China han crecido en los últimos años, debido a que China ha mostrado interés en los países latino-americanos y ha otorgado líneas de crédito. Sin embargo acorde a la investigación realizada se concluye que Ecuador se encuentra en una posición de desventaja en dichas negociaciones, principalmente por la venta anticipada de petróleo y la perdida monetaria que ello significa.

ANALYSIS OF THE ECONOMIC IMPACT OF ECUADOR'S TRADE RELATIONS WITH CHINA IN THE 2010 – 2013 PERIOD
Abstract
This article explores Ecuador's trade relations with China in the 2010-2013 period; it is focused in the credit lines that Ecuador has obtained for financing its projects. China is the second Largest Economic Power after the United States, the world's second oil consumer, the world's largest exporter and a country in search of natural resources to cover its domestic demand. Meanwhile Ecuador is a developing country that needs financing for projects and uses its raw materials as guarantee for funding. The aim of the research are to determine the level of debt that Ecuador currently has, in addition to determining the existence of benefits for Ecuador The study of trade balances, the pros and cons of each project, and loan terms are methods used to obtain results. Ecuador's trade relations with China have grown in recent years, as China has shown interest in Latin American countries and has granted many credit lines. However, according to the research done, Ecuador is in a disadvantaged position in these negotiations, mainly due to the anticipated sale of oil and the monetary loss that it represents.

Potential drug-drug interactions in the psychiatric hospital: Frequency analysis
Authors: Kirilochev Oleg O. , Dorfman Inna P. , Umerova Adelya R. , Bataeva Svetlana E. 
Published: December 2019

Introduction: Drug-drug interactions are an important clinical problem in pharmacotherapy. This study is focused on different types of drugs used in a psychiatric hospital.
Materials and methods: The pharmacoepidemiological study included the analysis of medical records of 500 psychiatric inpatients. The patients were divided into 2 groups: under 65 and over 65 years of age. All the drug prescriptions were analyzed to identify the combinations of drugs that can induce drug-drug interactions and determine their clinical significance.
Results and discussion: Over 77% of hospitalized patients were administered drug combinations that could induce drug-drug interactions, most of which were of moderate clinical significance. A reliable association was found between the patient’s age, the clinical significance of drug-drug interactions, and the pharmacotherapy structure. The most common irrational drug combinations were identified.
Conclusion: Timely analysis of drug prescriptions for potential drug-drug interactions can enhance the safety of pharmacotherapy and decrease the risk of adverse drug reactions in the psychiatric inpatient setting.
Le Samaritain, le bidonville qui voulait devenir un village
Authors: Cousin Saskia 
Published: December 2019

Organisé autour de l’église de la Samaritaine qui lui donne son nom, ce bidonville de La Courneuve (France) rassemblait, en 2015, environ trois cent trente personnes installées depuis sept ans. Alors que tous les recours juridiques pour empêcher l’expulsion étaient épuisés, un collectif constitué d’habitants et d’intervenants militants (santé, droits, architecture, plaidoyer) a monté un projet de sortie progressive du bidonville. Doté de moyens et de nombreux soutiens, il avait pour ambition de préserver le Samaritain, mais aussi de proposer des innovations sociales, culturelles et urbaines ayant valeur d’exemple. Après plusieurs mois de luttes et une immense mobilisation de soutien, le Samaritain a été expulsé en août 2015 : il fallait faire place nette pour la « COP 21 ».
Effectiveness of landscape decontamination following the Fukushima nuclear accident: a review
Authors: Evrard Olivier , Laceby J. Patrick , Nakao Atsushi 
Published: December 2019

Abstract. The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident in March 2011
resulted in the contamination of Japanese landscapes with radioactive
fallout. Accordingly, the Japanese authorities decided to conduct extensive
remediation activities in the impacted region to allow for the relatively
rapid return of the local population. The objective of this review is to
provide an overview of the decontamination strategies and their potential
effectiveness in Japan, focussing on particle-bound radiocesium. In the
Fukushima Prefecture, the decision was taken to decontaminate the
fallout-impacted landscapes in November 2011 for the 11 municipalities
evacuated after the accident (Special Decontamination Zone – SDZ – 1117 km2) and for the 40 non-evacuated municipalities affected by
lower, although still significant, levels of radioactivity (Intensive
Contamination Survey Areas, 7836 km2). Decontamination
activities predominantly targeted agricultural landscapes and residential
areas. No decontamination activities are currently planned for the majority
of forested areas, which cover ∼75 % of the main
fallout-impacted region. Research investigating the effectiveness of
decontamination activities underlined the need to undertake concerted
actions at the catchment scale to avoid renewed contamination
from the catchment headwaters after the completion of remediation
activities. Although the impact of decontamination on the radioactive dose
rates for the local population remains a subject of debate in the literature
and in the local communities, outdoor workers in the SDZ represent a group
of the local population that may exceed the long-term dosimetric target of
1 mSv yr−1. Decontamination activities generated ∼20 million m3 of soil waste by early 2019. The volume of waste generated
by decontamination may be decreased through incineration of combustible
material and recycling of the less contaminated soil for civil engineering
structures. However, most of this material will have to be stored for
∼30 years at interim facilities opened in 2017 in the
vicinity of the FDNPP before being potentially transported to final disposal
sites outside of the Fukushima Prefecture. Further research is required to
investigate the perennial contribution of radiocesium from forest sources.
In addition, the re-cultivation of farmland after decontamination raises
additional questions associated with the fertility of remediated soils and
the potential transfer of residual radiocesium to the plants. Overall, we
believe it is important to synthesise the remediation lessons learnt
following the FDNPP nuclear accident, which could be fundamental if a
similar catastrophe occurs somewhere on Earth in the future.
State of the Field—Mahmoud Darwish and His Poetics: Between Women and Intellectual Duties
Authors: Abu Eid Muna 
Published: December 2019

Abstract
This article focuses on women and love in Mahmoud Darwish's cultural and intellectual projects. Darwish (1941–2008), the most well-known Palestinian poet and author, evolved over time within the milieu of Palestinian and Arab poetic trends. How did his poetics affect women's status on both national and social levels? To what extent did women's issues or status in society preoccupy Mahmoud Darwish before and after the signing of the Oslo Peace Accords in 1994? Finally, to what degree did the poet's writings vis-à-vis women reflect his personal experiences and values? The article finds that in the early part of his career he used imagery that fused the woman with the homeland. In his later years, Darwish sided with those who argued that the improvement of the status of women must wait until after Palestinian independence is achieved.
Hazardous Waste: The Beginning of International Organizations Addressing a Growing Global Challenge in the 1970s
Authors: Borowy Iris 
Published: December 2019

Hazardous waste began gaining public attention in industrialized countries in the 1970s, partly as a result of several scandals involving former waste sites. Early on, several international organizations (IOs), notably the EEC, NATO, OECD and WHO, addressed the issue in publications, surveys and the collection of data. Collectively, these initiatives addressed crucial questions regarding the definition, collection, transportation and disposal of hazardous waste. Above all, they provided space and subtle pressure for national authorities to gather information about a problem which, so far, had been all but ignored. These programs revealed the improvised nature of much policy-making at the time but also offered the opportunity to consider hazardous waste management within larger development pathways. The perspectives taken during discussions at IOs vacillated between pragmatic, simple collection of data and superficial searching for short-term management in terms of trying to get rid of the substances and more principled considerations of how to find long-term solutions for hazardous waste through comprehensive approaches that integrated all stages of production from produce planning to disposal. Thus, IOs did not prevent the increasing spread of toxic materials into the environment. But they may have mitigated its form and paved the way for alternative development planning in the long run.

O cajuzinho-arbóreo-do-cerrado (Anacardium othonianum Rizz) é uma frutífera originária do Cerrado brasileiro. Observa-se um aumento expressivo na demanda por mudas de espécies nativas do cerrado por agricultores, empresas alimentícias e farmacêuticas. Entretanto, há pouca informação sobre técnicas de propagações de cajuzinho, entre elas, a produção in vitro torna-se uma técnica bastante promissora, todavia, há uma grande limitação de informações de produção in vitro a partir de sementes, justificando a busca de estratégias para a sua propagação. Assim, o objetivo desta pesquisa foi avaliar o cultivo in vitro de A. othonianum provenientes de distintos municípios e concentrações de sais do meio Murashige & Skoog (MS). Para avaliar o cultivo foram semeadas sementes de cajuzinho-arbóreo-do-cerrado provenientes de três municípios do estado de Goiás: Silvânia, Vianópolis e Orizona, em quatro concentrações de meio MS: 100, 75, 50 e 25 %, utilizando o delineamento inteiramente casualizado, conduzido em arranjo fatorial 3 x 4 em vinte repetições. Foram realizadas avalições diárias observando a ocorrência de oxidação, contaminação, sobrevivência e germinação. Os dados foram submetidos a análise estatística a partir de intervalos de 95% de confiança do software R versão 3.5.2. Concluiu-se que os meios MS 50 e 25 % foram mais eficientes na sobrevivência e germinação de A. othonianum.

Este estudio explora las actividades sexuales a través de internet y analiza la relación entre estas actividades y la satisfacción sexual. Un total de 236 estudiantes universitarios completaron self-reported scales. Los resultados indicaron que las actividades sexuales online más realizadas fue la búsqueda de temas sexuales, ligar a través de chats y consultar videos eróticos o pornográficos. Con respecto a la relación entre las actividades sexuales online y la satisfacción sexual, se encontró que los participantes que manifestaron no buscar información sexual así como no utilizar chats para conversaciones sexuales, obtuvieron una mayor puntuación en satisfacción sexual. En conclusión, aunque la realización de actividades a través de internet con fines sexuales tiene una alta prevalencia, no queda acreditada de manera suficiente su influencia en la obtención de una mayor satisfacción sexual.
This study explores online sexual activities and analyzes the relationship between these activities and sexual satisfaction. A total of 236 university students completed self-reported scales. The results indicated that the most frequent online sexual activities were: searching for sexual issues, flirting via chat rooms and viewing erotic or pornographic videos. With regards to the relationship between online sexual activities and sexual satisfaction, it was found that participants who reported not seeking sexual information as well as not using chatrooms for sexual conversations, obtained a higher score in sexual satisfaction. In conclusion, although engaging in activities online for sexual purposes has a high prevalence, its influence on obtaining greater sexual satisfaction is not sufficiently proven.
