Introduction Menstruation is the physiologic manifestation of cyclic uterine bleeding due to shedding and proliferation of the endometrium following invisible action and interplay of hormones mainly through the hypothalamus-pituitary-ovarian axis. Lack of proper menstrual hygiene predisposes women to different infectious and chronic obstetric and gynecological problems. Therefore, this study aimed to assess knowledge, attitude, practice and its associated factors of menstrual hygiene among high school students in North Wollo Zone, Woldia, Ethiopia.Methods A Facility based cross-sectional study was implemented from October 1-December 10, 2018. The data was collected using structured, pretested questioners among female high school students. Systematic random sampling technique was implemented. Data was entered and analyzed through Epi data 3.1 and SPSS respectively.Results This study revealed that 365(89.2%), 200(48.9%) and 196(47.9%) of the study participants have good knowledge, good practice and good attitude about menstrual hygiene respectively. Being grade 10 students [AOR=3.96, 95% CI =2.0-7.8], and having good practice of menstrual hygiene (AOR=2.52, 95% CI= 1.26-5) had positive association with menstrual hygiene knowledge. Maternal education level (AOR=1.86, 95% CI=1.18-2.9), being grade 10 students (AOR =2.3, 95% CI=1.48-3.56) were associated factors for practicing menstrual hygiene. Being grade 10 students (AOR=1.9, 95% CI=1.2-2.8), age ≥18 years (AOR=1.67, 95% CI=1.09-2.55) were statistically and positively associated with the attitude of menstrual hygiene.Conclusion This study revealed that the knowledge of the study participants towards menstrual hygiene was high whereas attitude and practice regarding menstrual hygiene was low. Being grade 10 students and having good practice were the associated factors of knowledge. Higher level maternal of education, being grade 10 students and having good knowledge towards menstrual hygiene were the identified associated factors for practicing of menstrual hygiene. Being grade 10 students and age ≥18 were statistically and positively associated with the attitude of menstrual hygiene. Therefore, creating awareness to reproductive health groups, educating their families and parents can change their poor practicing and attitude of menstrual hygiene.
Method for estimating non-study cigarette use among switchers to low nicotine content cigarettes in ambulatory clinical studies
Authors: Zhang Mingda , Edmiston Jeffery , Karles George , Smith Donna
Published: September 2019

Background FDA is considering to establish a product standard to reduce nicotine in cigarettes to make them “minimally addictive or nonaddictive.” FDA has funded many clinical studies where smokers are switched to smoking low nicotine cigarettes to determine a nicotine ceiling that is appropriate for the protection of the public health. Unlike typical clinical trials involving pharmaceuticals or medical devices, ambulatory studies with low nicotine cigarettes face a unique challenge in that conventional nicotine non-study cigarettes are readily available to participants when protocols require them to exclusively use study cigarettes. As a consequence, protocol deviation in non-study product use is a major limitation common in such ambulatory studies, with up to 80 percent of participants using non-study cigarettes during the study. There is no published method for estimating the magnitude of such protocol deviation, i.e., the number of non-study cigarettes smoked by participants, in such studies.Methods We present a method for estimating the magnitude of noncompliance based on the proposition that the level of biomarker of exposure to a smoke constituent is proportional to the amount of the constituent per cigarette and the number of cigarettes smoked by participants. The method estimates the number of non-study cigarettes smoked by participants based on the discrepancies between the yield of smoke constituents (e.g., nicotine) and the level of the corresponding biomarkers measured in a study.Results Data from a confined study confirmed the validity of this method. Under-reporting on the magnitude of non-study cigarette use is widespread across studies using different low nicotine cigarettes. Participants in one of the largest published studies under-reported the number of non-study cigarette used by 79-90%.Conclusions Controlling and accurately estimating non-study cigarette use is critical for ambulatory low nicotine cigarette switching studies to ensure the resulting data can be appropriately evaluated to support science-based regulatory decision-making. In planning future studies, researchers should consider incorporating specific biomarkers that would enable objective assessment of both the prevalence and the magnitude of non-study cigarette use.

Authors: Goossen Käthe , Hess Simone , Lunny Carole , Pieper Dawid
Published: September 2019

Background When conducting an Overviews of Reviews on health-related topics it is unclear which combination of bibliographic databases authors should use for searching for systematic reviews. Our goal was to determine which databases indexed the most systematic reviews and identify an optimal database combination for searching systematic reviews. Methods A set of 86 Overviews of Reviews with 1219 included systematic reviews was extracted from a previous study. Indexing of the systematic reviews was assessed in MEDLINE, CINAHL, DARE, Embase, Epistemonikos, PsycINFO, and TRIP. The mean indexing rate (% of indexed systematic reviews) and corresponding 95% confidence interval were calculated for each database individually, as well as for combinations of MEDLINE with other databases and reference checking. Results Indexing of systematic reviews was higher in MEDLINE than in any other single database (mean indexing rate 89.7%; 95% confidence interval [89.0–90.3%]). Combined with reference checking, this value increased to 93.7% [93.2–94.2%]. The best combination of two databases plus reference checking consisted of MEDLINE and Epistemonikos (99.2% [99.0–99.3%]). Stratification by Health Technology Assessment reports (97.7% [96.5–98.9%]) vs. Cochrane overviews (100.0%) vs. non-Cochrane overviews (99.3% [99.1–99.4%]) showed that indexing was only slightly lower for Health Technology Assessment reports. However, MEDLINE, Epistemonikos, and reference checking remained the best combination. Among the 10/1219 systematic reviews not identified by this combination, five were published as websites rather than journals, two were indexed in CINAHL and Embase, and one was indexed in the database ERIC. Conclusions MEDLINE/Epistemonikos, complemented by reference checking, is the best database combination to identify systematic reviews on health-related topics.

Objective: The objective of this study was to determine CYP2D6 phenotype in a Javanese and Sundanese healthy subject in Indonesia.Methods: Ninety unrelated healthy Indonesian subjects from Java and Sunda were studied. Metoprolol was used as phenotyping substrate. A 100 mgoral tablet of metoprolol was administered to all the subjects. Urinary metoprolol and α-hydroxymetoprolol were determined to calculate metoprololmetabolic ratio (MR). Determination of metoprolol and α-hydroxymetoprolol was carried out by high performance liquid chromatography method.Results: Metoprolol MR varied widely (from 0.08 to 72.75). One subject (1.11%) in the study was classified as poor metabolizer (PM), one subject(1.11%) as ultrarapid metabolizer, and the remaining 88 subjects (97.78%) were classified as extensive metabolizers.Conclusion: The frequencies of PM for the CYP2D6 phenotype (1.11%) in the Javanese and Sundanese population are in concordance with mostresults of oxidation metabolizers in other Asian populations.

Objective: The correct shaping of the socket for appropriate load distribution is a critical process in the design of lower limb prosthesis sockets.Several studies have been conducted to disclose these parameters; they can be divided into two methods: Experiment method and computationmethod. The finite element (FE) analysis has highly effective for study the interface pressure between the residual limb and socket. However, there isa little study focus on creating separate models of the socket and residual limb. Almost research using the same shape of socket and residual limb orusing the unreal model of the socket. This study will be given some solutions for the above issues.Methods: The author creates two models of the residual limb: Same and different with the shape of the socket. After that, the FE models weregenerated with appropriate conditions of the donning process. The experimental procedure was conducted for comparison and discussion with theresults of the simulation.Results: The results in case of different shape of socket and residual limb suggest that it is the better model for evaluating the interface pressure.Conclusions: The procedure developed through this work can be used by future researchers and prosthesis designers in understanding how to betterdesign the socket and transfemoral prostheses.
El declive de la utopía
Authors: Quintanilla Lourdes
Published: September 2019

La utopía es una ficción, una imaginaria representación de la mejor sociedad posible, la comunidad de la felicidad realizada. A lo largo de la historia occidental abundan los testimonios utópicos: Platón, Tomás Moro, Campanella. Hay también anti-utopías que revelan un profundo escepticismo frente a la realización de los sueños utópicos: Huxley, Orwell. Hoy se afirma que hay un declive de la utopía, pero lo que ha muerto es el proyecto racionalista que suprimía la fantasía y ahogaba la libertad. Así, podemos ahora asumir el presente como posibilidad, el instante como la cínica posesión: todos los mundos posibles están en éste y velar por él aquí y ahora supone no permitir la complicidad con un porvenir totalitario.
Afuera los dioses sonreían (la lección de los tiempos modernos)
Authors: García-Robles Jorge
Published: September 2019

Los tiempos modernos fracasaron. La felicidad prometida por los creyentes de la razón, de la ciencia y del progreso, nunca llegó. No se trata, sin embargo, de condenarlos sino de constatar este fracaso. El humanismo moderno no tiene un paradigma pero sí un espíritu, un sueño: hacer la historia confiando sólo en las fuerzas humanas. No abolió la religiosidad, la secularizó. Mantuvo los mismos deseos y anhelos de la Edad Media, pero con envoltura humana: el hombre y la historia son el ser supremo, la sustancia divina. Así, polarizó el ideal religioso y el humanista. La nueva cultura debe romper con el hábito de oponer los contrarios: masculino- femenino, cielo-tierra, mal-bien. Ha de ser andrógina, abalórica, y permitirse todas las posibilidades de ser.

La creación periodística
Authors: González Reyna Susana
Published: September 2019

La imaginación es un esfuerzo intelectual que gratifica y ayuda al desarrollo de la sensibilidad humana. Desde esta perspectiva el periodismo es: 1. La capacidad de tomar el suceso cotidiano en suceso noticioso; 2. La capacidad de rebasar el significado evidente del suceso y comprender lo que acontece y lo que significa en ese momento para ese grupo social; 3. Es la capacidad de asombrarse, de agudizar sentimiento e intelecto y comprender el fenómeno social más allá de su expresión primaria. Se hace una distinción entre el periodista registrador y el periodista creador.

El neorrealismo en la reflexión teórica contemporánea: una reseña crítica
Authors: Sarquís R. David Jamil
Published: September 2019

Después de presentar una sucinta reseña de los postulados realistas en el marco de la teoría de las relaciones internacionales, se revisan los aspeaos adicionales formulados por los neorrealistas, en gran medida para responder a las numerosas críticas que suscitaron los primeros. El autor retoma las críticas que hace Richard Ashley, a su vez, al neorrealismo, del cual señala que ha trabajado sobre la base de un “círculo de errores”, creando una construcción teórica cerrada que se retroalimenta a sí misma a partir de una mezcla de estatismo, utilitarismo, positivismo y estructuralismo.
Crisis capitalista e inversiones extranjeras directas (las norteamericanas en México)
Authors: Arellanes Jiménez Paulino E.
Published: September 2019

De las inversiones extranjeras directas que existen en México, particularmente en época de crisis, las norteamericanas siguen teniendo una posición central. Además, es relevante su presencia en sectores no tradicionales, sobre todo en aquellos que han impactado al país durante un buen tiempo como son el sector manufacturero y ahora el de servicios. Dado su monto, su distribución sectorial y su calidad, dicha inversión juega un papel de suma importancia en la economía nacional y en la crisis por la que el país atraviesa, e influye también ampliamente en las relaciones internacionales de éste y en la internacionalización de su economía, en beneficio de Estados Unidos.

Los usos de los conceptos de tiempo y espacio en las interpretaciones de la Revolución Mexicana
Authors: Heau Lambert Catherine , Rajchenberg Enrique
Published: September 2019

El estudio de las corrientes interpretativas actuales de la Revolución Mexicana constituye una perspectiva útil para el análisis crítico de las tendencias que imperan en el conjunto de las ciencias sociales. Los autores del artículo consideran que las interpretaciones de la Revolución pueden ser ordenadas para su estudio en tomo a la definición, explícita o no, vertida por cada uno de los conceptos de tiempo y espacio.

Es revisado el boom reciente de la historia regional y de la microhistoria que ha conducido a una suerte de escepticismo ante los paradigmas teóricos y a un rechazo de la teoría.
 Los autores formulan una propuesta de análisis que procura evitar tanto el teoricismo reduccionista de los procesos históricos como el empiricismo.
Política y neoliberalismo
Authors: Rodríguez Araujo Octavio
Published: September 2019

En este artículo se discute el neoliberalismo como un modelo político de repercusiones económicas, sociales y culturales que sirve de fundamento a un proceso de globalización económica de grandes grupos empresariales cuya característica principal es la exclusión de países y regiones, principalmente en el mundo subdesarrollado. Asimismo, son analizados los principales estragos en la población mayoritaria del planeta y en especial en el llamado Tercer Mundo, destacándose la clausura de expectativas para pueblos enteros y un proceso de indudable disolución de la unidad constitutiva del Estado y de los capitales nacionales. Se intenta, por lo tanto, una propuesta alternativa de lucha, en primera instancia, contra el modelo.

La semiología de la comunicación audiovisual y sus modelos
Authors: Jost François
Published: September 2019

Este artículo hace una revisión de los enfoques y modelos teóricos de la semiología que han aportado conceptos especialmente útiles para el análisis de la comunicación visual, particularmente aquéllos avanzados por Metz. Según el autor, la semiología intentó en un primer momento disociar el documento visual del mundo de la analogía y, en la actualidad, se propone identificar al responsable de la comunicación narrativa. Llega a la conclusión de que el responsable de la comunicación narrativa, y en particular de la audiovisual, por un lado rebasa el texto y, por el otro, depende del juicio del destinatario.
El sentido de democracia en la prensa mexicana
Authors: Molina y Vedia Silvia
Published: September 2019

El objetivo de este artículo es analizar el significado actual de la democracia a través de la prensa mexicana. Los principales temas tratados en el artículo se refieren al proceso de comunicación política, a la democracia tal como es enfocada en las noticias, al significado actual de la democracia y la victoria de la oposición y a los riesgos que enfrenta el desarrollo democrático en México. Las conclusiones demuestran que la información de prensa no es optimista con relación al desarrollo de la democracia en México. Pero estas conclusiones no son definitivas. Para optimizar el cambio democrático es necesario que el pueblo mexicano se proponga objetivos más ambiciosos que la simple alternancia en el poder. México será una nación democrática cuando su sociedad se decida a implementar una cultura democrática sobre la base de sus propias experiencias y valores. Condición para ello es dejar de lado la corrupción.

In Indonesia, 72.41% of urban residents can surf in cyberspace. Meanwhile, in rural-urban areas or areas between villages and cities, only 49.5% are connected to the internet. While in rural or rural areas only 48.3% are connected to the internet. By region, the composition of the largest internet users is on Java, which is 58.1%. After that in Sumatra with composition of 19% and Kalimantan 8%. While the other regions, namely Sulawesi, Bali-Nusa Tenggara, and Maluku-Papua, the composition is 6.7%, 5.6%, and 2.5% respectively. To overcome this problem, several efforts have been made to equalize internet access in Indonesia, and one of the efforts offered by Google companies is (Project Loon) which is a communication technology based on Hight Altitude Platform (HAPs). Based on this, it is necessary to analyze the feasibility of the Project Loon so that there is no overlap and regulatory errors in its implementation. In conducting a feasibility analysis, the Regulatory Impact Analysis (RIA) method is used to measure the feasibility of Project Loons in terms of frequency management by observing the potential frequencies available in Indonesia and the regulations currently available. So that it can be obtained a conclusion that the Project Loon allows it to be applied in Indonesia, but it requires regulations that regulate it mainly in terms of frequency.

Literacy overview shows that almost all of valuation researches for heritages have built demand curves as that of private goods. We argue that heritages are high-end purity public goods. A heritage valuation research would yield more accurate results if the demand curve could be built as that of a public good. This paper presents arguments of the superiority of the public good demand curve over that of private good in the scope of heritage valuation, and initially apply for Zonal Travel Cost Method (ZTCM) in valuating Hoi An, a World Heritage in Central of Vietnam, to look for evidences of such superiority. Evidences show that: (i) the relationship between visits and travel cost could be represented more accurately by the public good’s demand curve rather than the private good’s one; (ii) To build the demand curve for such a World Heritage (tourists are inhomogeneous) it requires additional technique to minimize potential distortions, in which the purchasing power parity ratio (PPP ratio) has been used to adjust inconsistence of actual traveling costs; (iii) The values of Hoi An has been valuated at US $ 4,255,724,958 USD in accordance with its public good’s demand curve, shows 206.6% higher than the value computed according to the private goods’ demand curve.

Authors: Wu Weijing
Published: September 2019

Recent events and developments in China's economic reform have exposed the inadequacy of China's bankruptcy infrastructure. In this context, a new People's Republic of China (PRC) bankruptcy law has been proposed. This essay examines the problems in the most recent draft pertaining to the initiation of bankruptcy proceedings. In contrast with the bankruptcy laws of the United States and France, China's draft presents ambiguities and imperfections in the threshold requirement. Accordingly, further improvements have been proposed to facilitate the commencement of bankruptcy proceedings in the PRC.

Background: Nail plants (Pteridophyta) are cormus plants whose bodies can be clearly distinguished between roots, stems, and leaves. However, ferns cannot produce seeds because they breed with spores. Nail plants are divided into 4 classes, namely (1) Psilophytinae (ancient nail); (2) Lycopodiinae (wire nail); (3) Equisetinae (horsetail); and (4) Filicinae (true nail). Community structure is a concept that studies species composition or composition and its abundance in a community.

Method: This research is a quantitative descriptive study to reveal information about the community structure of ferns. The study was conducted on July 18, 2018 - August 18, 2018.

Results: The ferns found in the Kusu-Kusu forest area were 10 species and the Soya region as many as 20 species. Overall the types of ferns found in the two study locations were grouped into 2 classes, namely Filicinae / Pteropsida (true nail) and Lycopodiinae (wire nails). The Filicinae / Pteropsida class has a greater number of species, both in the Kusu-Kusu forest area (8 species) and the Soya forest area (13 species). The Lycopodiinae class has a smaller number of species, both in the Kusu-Kusu forest area (2 types), and the Soya forest area (7 species).

Conclusions: 10 ferns were found in the Kusu-Kusu Sereh forest area in Nusaniwe Subdistrict, while in the Soya District of Sirimau District there were 20 species.

Purpose. Consider, reveal, what value graphic images occupy in traditional modern Japanese artistic tattoo. The methodology of this study is to apply general scientific methods of comparative historical and image-stylistic analysis. Considered, analyzed and identified the main graphic images that affect the formation and preservation of traditional Japanese artistic tattoos. These are images: groups of flora (sakura flower or chrysanthemums, maple leaf), groups of fauna (dragon, tiger, carp) and national, heroic, mythological and religious images (samurai, demons and gods). These are the features of the Japanese tattoo: asymmetry, characteristic figures, shading of the decorative contour and its deep saturation, contrast, dynamics of each individual construction, filling the void with texts and hieroglyphs, dominance of the main graphic images, a combination of small motifs and pronounced large scale images. Given the dynamics of development and the prospects for the spread of artistic tattoos, the features of the influence of graphic images on the preservation of national traditions in modern Japanese tattoos are highlighted. This approach allows us to determine the trends in the development of modern tattoo.
The Diffusion of Exclusion: Medieval Expulsions of Jews
Authors: Doten-Snitker Kerice
Published: September 2019

What social processes guide the spread of ethnic or racial exclusion? I investigate the diffusion of medieval expulsions of Jews among over 500 polities in the western Holy Roman Empire, 1385-1520 CE. For medieval governors, religious and material concerns were strong rationales against expulsion. Yet expulsions increase markedly in the fifteenth century. Did an expulsion by one government affect another government’s choices about expulsion? I appraise three common theories of policy diffusion: learning, social reinterpretation, and social structural and resource constraints. Statistical models provide evidence only for the latter two. While theological changes gave expulsion fresh political value, the adoption of expulsion followed political and economic incentives that were embedded in inter-city relationships of power and dependency. The results indicate that social influence, especially spatial proximity, cannot be assumed to accelerate ethnoracial extremism.

The present investigation was carried out to determine the genetic purity of the crosses in chickpea using SSR markers. The application of molecular markers SSR21 and SSR22 in F1 hybrids and their parental lines produced two bands indicating similarity among the hybrids and parental lines. The mixtures and off-types did not show similar banding pattern as compared to hybrids. The D2 analysis showed high amount of genetic diversity among parents and parental lines. The value of heterosis in a cross, JG 315 x ICCV 96029 was positive significantly higher for days to 50 % flowering, days to maturity, secondary branches plant-1, pods plant, biological yield and seed yield plant-1, however, it was significantly negative only for 100 seed weight.

The food industry has recognized the important role that multi-layered, flexible packaging materials play and it uses them extensively within the packaging processes. Trends within food processing and packaging continuously encourage manufacturers to develop new technologies which extend a product’s shelf-life. The samples that were the subject of research described in this paper are retort stand-up pouches made of multi-layered flexible material, the layers of which have been bonded with a laminating process that aims to both extend a product’s shelf-life and stability, permitting the final processing of the finished product under aggressive regimes. It is intended that packaging, when subjected to graphic reproduction and high pressure processing, shall remain unchanged in all aspects, in particular the visual aspect that is the subject of the research. The samples were printed on polyester film (PET) using a rotogravure printing technique and laminated on aluminum (Al), oriented polyamide (OPA) and finally on inner polypropylene (PP) layers. The sample was monitored for the Vegeta Blue spot colorimetric difference in the CIE L*a*b* space throughout the individual graphic reproduction phases and the final high pressure processing (HPP) of the finished product. The goal is to determine the size of the spot color colorimetric difference (Δ????????∗) in relation to the defined formula and the established standard. On the basis of measured results, guidelines and recommendations for the correction and quality assessment of spot color reproduction throughout the entire process were defined, with the goal to minimize any deviation to the lowest possible level.
