Capital market has a strategic role for strengthening the economic resilience of the country and as an alternative for profitable investment. Capital market has an important role in economics of the country due to the dual functions, economics function and finance. Capital market is a national driving force through its role as a source of financing for the company and alternative for investor to invest. In capital market, Indonesia important role as this index can be used as barometer on the economic health of the country. Macroeconomics factor is high inflation, interest rate, and depreciation of rupiah to dollar, could lower the stock price. The aim of this research is to study the effect of macro economy e.g. inflation, rupiah exchange rate, and interest rate on Indonesian Composite Index (IDX) at Indonesian Stock Exchange (ISE).Method of analysis is carried out using linear regression model equation. Data used in this study is secondary monthly data during the period of 2013-2016. Total number of 36 samples is used. The effect of inflation, interest rate / BI Rate and exchange rate to ISE on model equation is 41.61%.

El estudio muestra que se imponen la lógica y el sentido de pertenencia a una identidad cultural por encima de la de género o la de una ciudadanía capaz de construir consensos a través de la diferencia.
Violencia sexual en casos de tortura, un castigo adicional por ser mujer
Authors: Velázquez Moreno Ana Laura , Espinoza Solano Elizabeth
Published: November 2018

En México la tortura es considerada como un problema generalizado. Cuando durante la tortura existen actos de violencia sexual, los estragos generados por éstos se suman al sufrimiento y daños físicos y psicológicos que la tortura provoca por sí misma. Consideramos que este tipo de agresiones sexuales se presentan de forma frecuente en torturas perpetradas contra mujeres, esto como un ejercicio de poder y sumisión del victimario hacia la víctima, aunado a un contexto de violencia de género que prevalece a nivel nacional, en el que se considera que la mujer puede ser violentada y castigada utilizando su sexualidad como un medio para generar sufrimiento. En el presente trabajo se estudiaron las recomendaciones emitidas en los últimos cinco años por hechos de tortura por dos organismos defensores de derechos humanos, en las cuales se observó una tendencia de violencia sexual hacia las mujeres víctimas de tortura.
Jefatura femenina y reproducción precaria familiar en hogares de la ciudad de Zacatecas-Guadalupe. Rasgos y tendencias de 2004 a 2012
Authors: González Hernández José Roberto , González Carrillo Yolanda Guadalupe
Published: November 2018

El presente trabajo es un estudio de tendencia basado en encuestas aplicadas a hogares que en 2004 y en 2012 vivían en áreas periurbanas de la ciudad de Zacatecas-Guadalupe en México. El objetivo de este artículo es revisar si las condiciones relacionadas con la reproducción precaria familiar dentro de los hogares encuestados se han modificado considerando un enfoque que diferencie entre jefaturas de hogar masculina y femenina. Con ello se puede identificar y analizar las condiciones desventajosas en que los hogares con jefatura femenina experimentan las actividades cotidianas que permiten la reproducción social. Se concluye que la reproducción familiar se ha vuelto más precaria en esos ocho años en el grupo social estudiado y que los hogares con jefatura femenina experimentaron con mayor intensidad la precariedad de su reproducción familiar. Con ello, se fortalecen las afirmaciones acerca de la interacción dialéctica entre la jefatura femenina de hogares y la reproducción social precaria.
Propuesta de un programa de atención a la salud y prevención del consumo de alcohol en adolescentes hablantes del maya. Una primera aproximación desde la interculturalidad
Authors: Pacheco Trejo Aymé Yolanda , Pérez Briceño Juan Alberto
Published: November 2018

Es una realidad que los adolescentes de las comunidades indígenas de nuestro país representan un sector poblacional con severas carencias de salud, educación y derechos, entre otras necesidades imperantes. Problemas de salud como desnutrición, alcoholismo, drogadicción, vih / sida y suicidio, se encuentran con frecuencia en esta población como causas principales de mortalidad. Atender estas problemáticas de manera efectiva y urgente, necesariamente requiere alejarse del modelo médico hegemónico y acercarse a las comunidades con otra visión, desde un enfoque intercultural que incluya el conocimiento y respeto por la lengua, sus formas de comunicación, sus valores y creencias, así como su organización social y rescate de los recursos terapéuticos. En este contexto, se presenta el Programa de Atención Integral a la Salud para Adolescentes en Condiciones de Vulnerabilidad (paisav), el cual tiene como propósito general prevenir e intervenir en las conductas de riesgo que se han identificado con mayor incidencia en 300 estudiantes de secundaria, en tres comunidades de alto riesgo con población maya hablante de la región oriente del estado de Yucatán. La intervención se implementará en modalidad de talleres grupales en los salones de la escuela en el turno vespertino, dos veces por semana durante 4 meses. Se usará apoyo audiovisual, videos, diapositivas, música, además de folletos informativos y diferentes dinámicas participativas. Se concluye con una serie de recomendaciones derivadas de un primer acercamiento con una aplicación piloto del programa con 30 estudiantes: 15 hombres y 14 mujeres de la Escuela Secundaria No. 69 de Xocén, Valladolid, mismas que se integrarán en las aplicaciones subsiguientes del programa, a fin de mejorar el trabajo desde una perspectiva intercultural con población adolescente hablante del maya.

Loving the Other Beyond Death
Authors: Saghafi Kas
Published: November 2018

Turning to an example provided by Aristotle and taken up by Derrida in Politics of Friendship, which functions as a limit case—loving the other beyond death—I argue that Derrida's short-lived term, aimance, gently and lovingly contests the primacy given either to love or to friendship in the Western tradition, but also to the living act of loving and the figure of the lover, putting pressure on the very conceptual differences between these terms.
Seeking Justice in the Midst of War: The Experience of War for Chinese Christians as Revealed inThe True Light Review, 1937–1941
Authors: Kwok Wai Luen
Published: November 2018

This paper aims to offer a critique of the traditional just war theory and pacifist claims through analysing how Chinese Christians as civilians sought a sense of justice in the midst of war through the medium of a Christian periodical. During 1937 to 1941, The True Light Review was edited and published in the isolated Shanghai International Settlement. Through a dialogue with the debate of the Niebuhr brothers on just war, I argue that the literary discourses in The True Light Review are a kind of ‘realistic ethic’ used to seek an understanding of justice in the midst of war and violence. They show us that, from a world Christianity perspective, the traditional just war and pacifism dichotomy has its limitation. They lead us to propose a new understanding of Christian justice in war.
Total Phenolic Content and Antioxidant Activity of Yacon (Smallanthus Sonchifolius Poepp. and Endl.) Chips: Effect of Cultivar, Pre-Treatment and Drying
Authors: Khajehei Forough , Hartung Jens , Graeff-Hönninger Simone
Published: November 2018

Recent studies have associated the consumption of yacon root as a functional plant food with reduced glycemic index and, due to its considerable phenolic acid levels, a protection of cell membranes against free radical damage. This study examined the effect of four different treatments including: (1) storage duration after harvest (one and three weeks after harvest); (2) pre-treatment before drying (untreated, pre-treatment with diluted lime juice); (3) drying method (freeze drying (FD) and convective hot air drying (CHAD)); and (4) cultivar (white and red), on the quality of yacon (Smallanthus sonchifolius Poepp. and Endl.) chips in terms of their total phenolic content (TPC) and antioxidant activity (AA) (ABTS (2,2′-Azino-Bis (3-Ethylbenzothiazoline-6-Sulfonic Acid) Diammonium Salt) radical scavenging activity, DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity and ferric reducing antioxidant power (FRAP)). Overall, the chips that were produced using pre-treatment with diluted lime juice and FD had the highest amounts of TPC and AA. Regarding the chips produced by means of CHAD, retention of higher TPC and AA was possible with lime-juice pre-treatment and use of higher hot air temperatures. Moreover, chips produced from the white cultivar had higher TPC and AA than chips produced from the red cultivar.
Exogenously Applied Nitric Oxide Enhances Salt Tolerance in Rice (Oryza sativa L.) at Seedling Stage
Authors: Adamu Teferi Alem , Mun Bong-Gyu , Lee Sang-Uk , Hussain Adil , Yun Byung-Wook
Published: November 2018

Salinity is one of the major abiotic factors that limit rice production worldwide. Previous trends show that salt concentration in rivers is increasing consistently, posing potentially adverse threats in the near future. Thus, crops currently being cultivated, particularly in small-scale farming systems, are under high threat from salinity. In this study, we investigated the mitigating effect of nitric oxide (NO) on salt stress in rice based on the assessment of changes in the transcript levels of different genes and the phenotypic response of rice genotypes. We observed that exogenously applied NO increased the expression levels of OsHIPP38, OsGR1, and OsP5CS2 in the susceptible genotype of rice, whereas in the tolerant genotype, the effect of NO was mainly in counteracting the salt-induced gene expression that diverts cellular energy for defense. Moreover, seedlings that were pretreated with NO showed high biomass production under salt stress conditions, indicating the positive role of NO against salt-induced leaf chlorosis and early senescence. The effect of NO-mediated enhancement was more pronounced in the salt tolerant genotype. Therefore, the use of NO with the integration of tolerant genes or genotypes will enhance salt tolerance levels in rice.
Microwave Deicing Efficiency: Study on the Difference between Microwave Frequencies and Road Structure Materials
Authors: Ding Longting , Wang Xuancang , Zhang Wengang , Wang Shuai , Zhao Jing , Li Yongquan
Published: November 2018

A method of deicing using microwave heating is proposed to make scientific and economical road deicing in a cold area, and to make up for deficiencies in the existing methods for melting snow and ice. This paper proposes to define microwave deicing efficiency as the heating rate of a concrete surface when heated to 0 °C (the efficiency of deicing is equal to the difference divided by heating time, which is between 0 °C and the initial temperature at the junction of ice and concrete). Based on the mechanism of microwave heating and deicing, a method combining the finite element simulation model with indoor experiments was proposed to study the deicing efficiency of microwaves, and the effects of different microwave frequencies and different road structure materials on microwave deicing efficiency were analyzed. The results show that the microwave frequency and road structure materials have a great influence on microwave deicing. For asphalt concrete, the ice melting efficiency of 5.8 GHz is 4.31 times that of 2.45 GHz, but the heating depth is less than that of 2.45 GHz. At 2.45 GHz, the melting efficiency of cement concrete is 3.89 times that of asphalt concrete. At 5.8 GHz, the melting efficiency of cement concrete is 5.23 times that of asphalt concrete. Through the consistency of the simulation and experimental results, the validity of the simulation model based on the finite element theory is verified. The results provide theoretical guidance and a practical basis for future applications of microwave deicing.
The Electronic, Magnetic, Half-Metallic and Mechanical Properties of the Equiatomic Quaternary Heusler Compounds FeRhCrSi and FePdCrSi: A First-Principles Study
Authors: Feng Liefeng , Ma Jiannan , Yang Yue , Lin Tingting , Wang Liying
Published: November 2018

By using the first-principles method, the electronic structures and magnetism of equiatomic quaternary Heusler alloys FeRhCrSi and FePdCrSi were calculated. The results show that both FeRhCrSi and FePdCrSi compounds are ferrimagnets. Both compounds are half-metals and their half-metallicity can be maintained in a wide range of variation of the lattice constant under hydrostatic strain and c/a ratio range under tetragonal distortion, implying that they have low sensitivity to external interference. Furthermore, the total magnetic moments are integers, which are typical characteristics of half-metals. The calculated negative formation energy and cohesive energy indicate that these two alloys have good chemical stability. Furthermore, the value of the elastic constants and the various moduli indicate the mechanical stability of these two alloys. Thus, FeRhCrSi and FePdCrSi are likely to be synthesized in the experiment.
Vibing with Blackness: Critical Considerations of Black Panther and Exceptional Black Positionings
Authors: Marco Derilene (Dee)
Published: November 2018

This article considers different ways in which Blackness is represented as exceptional in the 2018 film Black Panther. It also considers other iterations of Black visibility and legibility in the current popular culture context which appears to privilege Black narratives in interesting ways. The essay uses conceptual lenses from diaspora studies, Afro science fiction and Black feminist studies to critically engage the film and to critically question the notion of Black exceptionalism.
Tracing the Provenance of Long-Range Transported Dust Deposition in Cryospheric Basins of the Northeast Tibetan Plateau: REEs and Trace Element Evidences
Authors: Wei Ting , Dong Zhiwen , Kang Shichang , Ulbrich Sven
Published: November 2018

Based on cryoconite and snow dust samples collected from various glaciers and snowpacks in northeast Tibetan Plateau (NETP) margin and surrounding areas, this study investigated the rare earth element (REE) and trace element composition of long-range transported (LRT) dust in glacier surfaces at the NETP locations, in order to trace its source areas and the transport over the region. Results showed that the deposited dust in NETP mainly originated from the adjacent Qaidam Basin, Badain Jaran and Taklimakan Deserts based on the similarity in (La/Sm)N, Th/YbN and Nb/YbN ratios. However, most samples collected at Miaoergou Glacier (MG) located in the Tianshan Mountains showed very different rare earth elements (REEs) ratios from the above locations attributed to the dominant contribution of LRT dust emitted by the southern Gobi Deserts. We found that large central Asian deserts rarely contributed LRT dust to Yuzhufeng (YG) in the hinterland Tibetan Plateau (TP). Taking the region as a whole, it was found that most of the glacier and snowpacks showed mixed dust sources and inputs from different parts of surrounding central Asian deserts that are characterized by different mineralogical settings. Geochemical data indicated that the NETP region acts as an important channel for aeolian transport from large Asian deserts into Loess Plateau and eastern regions, with atmospheric circulations bringing plenty of dust particles deposition to the high-altitude glacier surface in NETP margin. This work is of great importance in providing a new complete view of LRT aeolian emission and transport over the NETP region.

Published: November 2018

Liquid crystals are defined as the fourth state of matter forming between solid and liquid states. Earlier the applications of liquid crystals were confined to electronic instruments, but recent research findings suggest multiple applications of liquid crystals in biology and medicine. Here, the purpose of this review article is to discuss the potential biological impacts of liquid crystals in the diagnosis and prognosis of cancer along with the risk assessment. In this review, we also discussed the recent advances of liquid crystals in cancer biomarker detection and treatment in multiple cell line models. Cases reviewed here will demonstrate that cancer diagnostics based on the multidisciplinary technology and intriguingly utilization of liquid crystals may become an alternative to regular cancer detection methodologies. Additionally, we discussed the formidable challenges and problems in applying liquid crystal technologies. Solving these problems will require great effort and the way forward is through the multidisciplinary collaboration of physicists, biologists, chemists, material-scientists, clinicians, and engineers. The triumphant outcome of these liquid crystals and their applications in cancer research would be convenient testing for the detection of cancer and may result in treating the cancer patients non-invasively.

Published: November 2018

To investigate whether peripheral blood biomarkers predict the outcome of anti-PD-1 antibody treatment for head and neck squamous cell carcinoma (HNSCC). Patients treated with nivolumab for platinum-refractory recurrent or metastatic HNSCC were retrospectively reviewed. Fifty-three patients treated between April 2017 and March 2018 were included in the study. The median progression-free survival (PFS) and overall survival (OS) were 2.5 and 8.7 months, respectively. In the univariate analysis, performance status (PS) ≥ 3, relative neutrophil count ≥ 0.65, relative lymphocyte count ≥ 0.17, and relative eosinophil count (REC) ≥ 0.015 were significantly associated with both PFS and OS. On multivariate analysis, PS ≥ 3 and REC ≥ 0.015 were significantly associated with PFS and OS. Low REC and poor PS were independent poor prognostic factors for both PFS and OS in patients with recurrent or metastatic HNSCC treated with nivolumab.
An Attack Bound for Small Multiplicative Inverse of φ(N) mod e with a Composed Prime Sum p + q Using Sublattice Based Techniques
Authors: Kameswari Pratha Anuradha , Jyotsna Lambadi
Published: November 2018

In this paper, we gave an attack on RSA (Rivest–Shamir–Adleman) Cryptosystem when φ ( N ) has small multiplicative inverse modulo e and the prime sum p + q is of the form p + q = 2 n k 0 + k 1 , where n is a given positive integer and k 0 and k 1 are two suitably small unknown integers using sublattice reduction techniques and Coppersmith’s methods for finding small roots of modular polynomial equations. When we compare this method with an approach using lattice based techniques, this procedure slightly improves the bound and reduces the lattice dimension. Employing the previous tools, we provide a new attack bound for the deciphering exponent when the prime sum p + q = 2 n k 0 + k 1 and performed an analysis with Boneh and Durfee’s deciphering exponent bound for appropriately small k 0 and k 1 .

Published: November 2018

Being sustainable, clean, and eco-friendly, photovoltaic technology is considered as one of the most hoped solutions face to worldwide energetic challenges. Morocco joins this context with the inauguration of numerous clean energy projects. However, one key factor in making photovoltaic installations a profitable investment are regular and effective inspections in order to detect occurred defects. Unmanned aerial vehicles (UAV) are increasingly used in various inspection fields. In this respect, this work focuses on the use of thermal and visual imagery taken by UAV in the inspection of photovoltaic installations. Visual and thermal images of photovoltaic modules, obtained by UAV, from different installations, and with different acquisition conditions and parameters, were exploited to generate orthomosaics for inspection purposes. The methodology was tested on a dataset we have acquired by a mission in Rabat (Morocco), and also on external datasets acquired in Switzerland. As final results, several visual defects were detected in visual RGB and thermal orthomosaics, such as cracks, soiling, and hotspots. In addition, a procedure of semi-automatic hotspots’ extraction was also developed and is presented within this work. On the other side, various tests were conducted on the influence of some acquisition and processing parameters (images’ overlap, the ground sampling distance, the flying height, the use of ground control points, the internal camera parameters’ optimization) on the detection of defects and the quality of visual and thermal generated orthomosaics. In the end, the potential of UAV thermal and visual imagery in the inspection of photovoltaic installations was discussed in function of various parameters. On the basis of the discussion feedback, UAV were concluded as advantageous tools within the thematic of this project, which proves the necessity of their implementation in this context.
Magnetization-Dependent Core-Loss Model in a Three-Phase Self-Excited Induction Generator
Authors: Al-Senaidi Saleh H. , Alolah Abdulrahman I. , Alkanhal Majeed A.
Published: November 2018

Steady-state, transient, as well as dynamic analyses of self-excited induction generators (SEIGs) are generally well-documented. However, in most of the documented studies, core losses have been neglected or inaccurately modeled. This paper is concerned with the accurate modeling of core losses in SEIG analysis. The core loss is presented as a function related to the level of saturation. This relation is determined experimentally and integrated into a nonlinear model of the SEIG. The nonlinear model is solved using a mathematical optimization scheme to obtain the performance parameters of the SEIG. A new set of curves describing accurate behavior of the SEIG parameters is produced and presented in this paper. The computed parameters of the model are validated experimentally, and the agreement attained demonstrates the functionality and accuracy of the proposed core-loss model.
The Influence of the Use of Windrowers in Baler Machinery on the Energy Balance during Pruned Biomass Harvesting in the Apple Orchard
Authors: Dyjakon Arkadiusz
Published: November 2018

The effective operation of machinery in agricultural processes is crucial in terms of energy efficiency, economic consequences, and environmental footprint. The agricultural sector provides many opportunities to bring biomass to the market. An interesting option is to collect the branches after a regular pruning of apple orchards in the winter-spring season. As the harvesting of pruning residues in apple orchards for energy purposes demands additional primary energy, any measures that increase the amount of collected biomass are desirable. In this study, the influence of pruning harvesting using a baler with and without windrowers on pruning biomass yield, energy input and output flow, energy balance, CO2 emission reduction, and costs of that operation in apple orchards was investigated. The performed analysis, based on the results from two apple orchards, revealed that the energy balance was positive for both variants. However, in comparison with the harvesting process without windrowers, the use of windrowers in these two orchards caused an increase in pruning biomass yield by 0.45 tDM·ha−1 per year (25%) and 0.54 tDM·ha−1 per year (33%), respectively. The energy balance increased up by ca. 0.8–1.0 GJ·ha−1, although the fuel consumption by the tractor was higher. The use of windrowers did not significantly increase the costs, but resulted in remarkably better income from biomass selling (ca. €30–40 ha−1). Finally, the increase in the mass of harvested biomass led to a higher potential CO2 emission reduction. As a result, pruning biomass is an attractive source of energy, especially for local markets.
Controlling a Switched Reluctance Motor with a Conventional Three-Phase Bridge Instead of Asymmetric H-Bridges

Published: November 2018

This paper proposes a new driving method for switched reluctance motors (SRMs) using the standard full-bridge inverter. In spite of changing the internal structure of an SRM, the proposed method uses an extra ring structure circuit to make it possible for the inverter to drive the SRM. Next to the standard converter, a controllable DC source is needed. With theoretical analysis and calculation, the reference value of the circulating current in the ring structure was determined and the new method was proven via simulation. A comparison was made with the conventional method for driving an SRM: the asymmetric H-bridges. Also, the current studies were then made to confirm that the SRM could be controlled without lowering the performance of the machine. Experimental verification was also made under different conditions, as well as comparison with the simulation results.
Capacitors Voltage Switching Ripple in Three-Phase Three-Level Neutral Point Clamped Inverters with Self-Balancing Carrier-Based Modulation
Authors: Hammami Manel , Rizzoli Gabriele , Mandrioli Riccardo , Grandi Gabriele
Published: November 2018

This paper provides a comprehensive analysis of the capacitors voltage switching ripple for three-phase three-level neutral point clamped (NPC) inverter topologies. The voltage ripple amplitudes of the two dc-link capacitors are theoretically estimated as a function of both amplitude and phase angle of output current and the inverter modulation index. In particular, peak-to-peak distribution and maximum amplitudes of the capacitor voltage switching ripple over the fundamental period are obtained. A comparison is made considering different carrier-based pulse-width modulations in the case of almost all sinusoidal load currents, representing either grid connection or passive load with a negligible current ripple. Based on the voltage switching ripple requirements of capacitors, a simple and effective original equation for a preliminary sizing of the capacitors has been proposed. Numerical simulations and experimental tests have been carried out in order to verify the analytical developments.

Optimizing key parameters with energy consumption as the control target can minimize the heating and cooling needs of buildings. In this paper we focus on the optimization of performance parameters design and the prediction of energy consumption for nearly Zero Energy Buildings (nZEB). The optimal combination of various performance parameters and the Energy Saving Ratio (ESR)are studied by using a large volume of simulation data. Artificial neural networks (ANNs) are applied for the prediction of annual electrical energy consumption in a nearly Zero Energy Building designs located in Shenyang (China). The data of the energy demand for our test is obtained by using building simulation techniques. The results demonstrate that the heating energy demand for our test nearly Zero Energy Building is 17.42 KW·h/(m2·a). The Energy Saving Ratio of window-to-wall ratios optimization is the most obvious, followed by thermal performance parameters of the window, and finally the insulation thickness. The maximum relative error of building energy consumption prediction is 6.46% when using the artificial neural network model to predict energy consumption. The establishment of this prediction method enables architects to easily and accurately obtain the energy consumption of buildings during the design phase.

The sweetness seismic attribute is a very useful tool for proper description of the depositional environment, reservoir quality and lithofacies discrimination. This paper shows that depositional channels and turbidity sandstones deposited during the Upper Pannonian and Lower Pontian in the Sava Depression can be described using porosity–thickness and sweetness seismic attribute maps. Two studied reservoirs are of Neogene stage (“UP” reservoir of Upper Pannonian age and “LP” reservoir of Lower Pontian age) and located in the Sava Depression, Croatia. Both reservoirs contain medium to fine grained sandstones that are intercalated with basinal marls. A comparison of the sweetness seismic attribute and porosity–thickness maps show a good visual match with correlation coefficient of approximately 0.85. A mismatch was observed in areas with small reservoir thickness. This work demonstrates the importance of using porosity–thickness maps for reservoir characterization. The workflow presented in this work has wider applications in frontier areas with poor seismic data or coverage.

Permafrost degradation of coastal and marine sediments of the Arctic Seas can result in large amounts of methane emitted to the atmosphere. The quantitative assessment of such emissions requires data on variability of methane content in various types of permafrost strata. To evaluate the methane concentrations in sediments and ground ice of the Kara Sea coast, samples were collected at a series of coastal exposures. Methane concentrations were determined for more than 400 samples taken from frozen sediments, ground ice and active layer. In frozen sediments, methane concentrations were lowest in sands and highest in marine clays. In ground ice, the highest concentrations above 500 ppmV and higher were found in massive tabular ground ice, with much lower methane concentrations in ground ice wedges. The mean isotopic composition of methane is −68.6‰ in permafrost and −63.6‰ in the active layer indicative of microbial genesis. The isotopic compositions of the active layer is enriched relative to permafrost due to microbial oxidation and become more depleted with depth. Ice-rich sediments of Kara Sea coasts, especially those with massive tabular ground ice, hold large amounts of methane making them potential sources of methane emissions under projected warming temperatures and increasing rates of coastal erosion.

Background: Gallbladder diseases are common in Jilin, China. However, there have been few previous studies on this disease. Our study used the chronic disease database in Jilin Province to study the factors correlated with gallbladder diseases. Methods: A total of 21,435 people were selected from the Jilin Province adult chronic disease survey conducted in 2012. Multistage stratified random cluster sampling was used in this cross-sectional study. Multiple logistic regression analysis was used to explore the independent associations of different factors with gallbladder diseases. Results: There were 1876 people with gallbladder diseases, and the prevalence of the diseases was 8.8% (males 4.4%, females 12.8%). Multivariate logistic regression analysis showed that female (prevalence odds ratio (POR) = 3.13, 95% confidence intervals (CIs): 2.76–3.55), older people (30–45 years (POR = 2.79, 95% CIs: 2.06–3.77), 45–60 years (POR = 4.26, 95% CIs: 3.17–5.73), 60–79 years (POR = 4.72, 95% CIs: 3.48–6.41)), people living in rural areas (POR = 1.65, 95% CIs: 1.49–1.82), smoking (current smoker (POR = 1.15, 95% CIs: 1.01–1.31), former smoker (POR = 1.37, 95% CIs: 1.13–1.66)), high frequency of eating seafood (POR = 0.77, 95% CIs: 0.63–0.93), and high frequency of eating soy products (POR = 0.50, 95% CIs: 0.44–0.58) were associated with gallbladder diseases. Conclusions: We found that there were some factors associated with gallbladder disease, and there needs to be further studies to confirm these associations.

Both periodontal disease (PD) and inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), are important diseases of the alimentary tract. Microbiome and immune-mediated inflammatory processes play important roles in these diseases. An association between PD and IBD may exist. This study investigated the risk of IBD in patients with PD. This study used data from the National Health Insurance Research Database of Taiwan from 1996 to 2013. A total of 27,041 patients with PD were enrolled as a study group, and 108,149 patients without PD were selected as the control group after matching by gender, age, insured region, urbanization, and income with a 1:4 ratio. Cox proportional hazards regression was used to calculate the risk of IBD. Of the 135,190 participants enrolled in this study, 5392 (4%) with newly diagnosed IBD were identified. The overall incidence of subsequent IBD was similar in both groups (3.8% vs. 4%, adjusted hazard ratio (aHR) = 1.01, 95% confidence interval (CI): 0.94–1.08). However, an increased risk of UC in the PD group was found after adjusting confounding factors (aHR: 1.56, 95% CI: 1.13–2.15; p < 0.05). This study demonstrated that patients with PD had approximately one-half higher risk of subsequent UC. Further studies are warranted to elucidate the relationship between PD and UC.

Published: November 2018

Among available home and community-based services in Taiwan, there should be a focus on providing people with people-centered, value-based services. This study aims to follow up the people-centered health outcomes of care recipients and to examine the factors associated with to feedback for policy and practice in long-term care. A total of 9889 persons from the long-term care dataset were followed up for two years (T0–T4). The Cox Proportional Hazard Regression analyses to analyze mortality and the mixed effect models for health outcomes were used. Three classes among the care recipients were identified. Health profiles (HR = 1.46 and 2.56 for FI and FD compared with RI, p < 0.001), subsidy gap (HR = 1.01), and living status (HR = 0.88 for those living with spouse only) had a significant impact on mortality. The overall dropout rate was 52.3% at two years, and the health profiles at baseline significantly influenced the health outcome’s change. The health heterogeneity matters and influences subsequent outcomes. To reach the goal of the HCBS, regular and exact monitoring of care recipients is crucial, while feedback regarding health outcomes and a greater focus on providing person-centered and responsive services in the community are also required.

Published: November 2018

Background: The aim of this study was to estimate the prevalence of diabetes mellitus in the Roma population and compare it to the prevalence in the Caucasian population. Methods: Using the words “Roma”, “Gypsies”, “Romani”, and ”traveler” in combination with “diabetes, “metabolic syndrome”, “cardiovascular disease” and “health status” we searched the MEDLINE, Pubmed and Scopus databases for articles in English that focused on the prevalence of diabetes mellitus among Roma populations published until December 2017. Results: Five studies met the inclusion criteria. The results of four of them suggested a higher prevalence of diabetes among Romani compared to Caucasians but none of them reached the standards regarding representative samples and number of cases for a conclusive result. Conclusion: Although some of the existing studies suggest a substantial prevalence of diabetes among Roma populations and even a higher risk of developing diabetes for Roma persons compared to Caucasians, the number of published literature on this topic remains very low and insufficient in design and number of participants to draw any conclusions.
