Authors: Shrestha Soni , Gautam Deepa 
Published: February 2017

Background: Progressive urbanization and adoption of the “western” lifestyle contributes to the rising burden of cardiovascular diseases in the developing world. Coronary Heart Disease (CHD) is no longer confined by geographical area or socioeconomic boundary. Knowledge is an important pre-requisite for implementing both primary and secondary preventive strategies of CHD and for behavioral change. Objective: This study attempts to quantify level of knowledge on risk factors of Coronary Heart Disease among middle aged administrative staffs of Tribhuvan University, Kritipur Kathmandu.Methodology: Descriptive Cross Sectional study was conducted in different departments of Tribhuvan University, Kathmandu from December 22, 2014 to January 2, 2015.A total of 130 middle aged administrative staffs (40-60 years) have participated in the study. Structured questionnaires and interview schedule were used to collect data and descriptive statistics was used for data analysis. Results: Among total respondents, 56.2 % had mean knowledge score equal to or more than 13.91. Only less than half (47.7%) knew age as non - modifiable risk factor of CHD followed by sex (30.8%) and family history (30%). Regarding modifiable risk factors, most participant response was fatty food consumption (80.8%) followed by tobacco use (80%), excessive alcohol consumption (78.5%), hypertension(76.2%), Stress(74.6%), lack of exercise/inactive lifestyle (73.8%), mellitus (46.9%). In regards to the symptom of CHD, most cited response was chest Obesity (70.8%), excessive salt consumption in diet (60.8%) and diabetes pain/discomfort (55%). The risk factors prevalent among the study participants included overweight (44.6%) and alcohol consumption (30.8%)Conclusion: The findings concluded that significant percentage (43.8%) of respondent’s mean knowledge score was less than 13.91. Thus, understanding of the behavioral determinants of heart disease knowledge and risk factors is necessary in designing effective prevention strategies.

Authors: Rayamajhi Kedar Bahadur 
Published: February 2017

Stress is the mental phenomenon; caused from the various environmental factors. The main aim of this study is to explore relationship between the role-stress and mental health of government officer working under the different ministries of Nepal. The study was conducted among the 284 government officers comprising level I to III. Standard structured questionnaires were used to measure the role-stress and mental health. The study found that there was no significant difference between position regarding the impact of organizational role stress on their mental and physical health. There was no significant difference found between the class I and III at P = 1.000 followed by class I and II at P = 1.000 and class III and class II at P = 1.000. Data shows that perception of mental and physical health has no different on the basis of their position and job roles. The study observed that there is relationship between the role-stress and mental health. If role stress increased then it negatively effect in mental health. Government employee reported the effect of role stress in their daily life but study has not found the serious effect of role stress in mental health of employees because of their practices of coping mechanism. So, there is need to explore their coping mechanism to manage the stress. Journal of Advanced Academic Research Vol. 3, No. 2, 2016, Page: 40-54
Stereoscopic Correspondence of Particles for 3-Dimensional Particle Tracking Velocimetry by using Genetic Algorithm
Authors: Panday Sanjeeb Prasad 
Published: February 2017

The genetic algorithm (GA) based stereo particle-pairing algorithm has been developed and applied to the spatial particle-pairing problem of the stereoscopic three-dimensional (3-D) PTV system. In this 3 D PTV system, particles viewed by two (or more than two) stereoscopic cameras with a parallax have to be correctly paired at every synchronized time step. This is important because the 3-D coordinates of individual particles cannot be computed without the knowledge of the correct stereo correspondence of the particles. In the present study, the GA algorithm is applied to the epipolar line proximity analysis for establishing correspondence of particles pairs between two co-instantaneous stereoscopic particles images, in order to compute the 3-D coordinates of every individual particle. The results are tested with various standard images and it’s found that the new strategy using GA works better than conventional particle pairing methods of 3-D particle tracking velocimetry for steoroscopic PTV.

Queens of Bombus diversus tersatus (Hymenoptera: Apidae) are innately attracted to floral scents emitted by Cremastra appendiculata (Orchidaceae)
Authors: Kubo Ryohei , Ono Masato 
Published: February 2017

AbstractThe rewarding orchid, Cremastra appendiculata (Orchidaceae), has a strong floral scent and is pollinated by long-tongued bumble bee queens (Bombus diversus tersatus Smith; Hymenoptera: Apidae). The response of queens of B. diversus tersatus to the scent of C. appendiculata was investigated using a gas chromatography–electroantennographic detector system and Y-tube olfactometer. Gas chromatography–electroantennographic detector analysis of flower extracts showed that seven compounds (nerol, methyl decanoate, methyl dodecanoate, methyl tetradecanoate, methyl hexadecanoate, ethyl dodecanoate, and ethyl tetradecanoate) elicited antennal responses from B. diversus tersatus queens. Further, Y-tube olfactometer test results showed that queens significantly preferred both the flower extracts and synthetic mixture of seven EAD active compounds compared with pentane (a solvent control). These results suggest that floral scents play an important role in attracting queens and promote successful pollination.

Abstract. The presence of airborne aerosols affects the meteorology as it induces a perturbation in the radiation budget, the number of cloud condensation nuclei and the cloud micro-physics. Those effects are difficult to model at regional scale as regional chemistry-transport models are usually driven by a distinct meteorological model or data. In this paper, the coupling of the CHIMERE chemistry-transport model with the WRF meteorological model using the OASIS3-MCT coupler is presented. WRF meteorological fields along with CHIMERE aerosol optical properties are exchanged through the coupler at a high frequency in order to model the aerosol–radiation interactions. The WRF-CHIMERE online model has a higher computational burden than both models run separately in offline mode (up to 42 % higher). This is mainly due to some additional computations made within the models such as more frequent calls to meteorology treatment routines or calls to optical properties computation routines. On the other hand, the overall time required to perform the OASIS3-MCT exchanges is not significant compared to the total duration of the simulations. The impact of the coupling is evaluated on a case study over Europe, northern Africa, the Middle East and western Asia during the summer of 2012, through comparisons of the offline and two online simulations (with and without the aerosol optical properties feedback) to observations of temperature, aerosol optical depth (AOD) and surface PM10 (particulate matter with diameters lower than 10 µm) concentrations. The result shows that using the optical properties feedback induces a radiative forcing (average forcing of −4.8 W m−2) which creates a perturbation in the average surface temperatures over desert areas (up to 2.6° locally) along with an increase in both AOD and PM10 concentrations.
Developing a representative snow-monitoring network in a forested mountain watershed

Abstract. A challenge in establishing new ground-based stations for monitoring snowpack accumulation and ablation is to locate the sites in areas that represent the key processes affecting snow accumulation and ablation. This is especially challenging in forested montane watersheds where the combined effects of terrain, climate, and land cover affect seasonal snowpack. We present a coupled modeling approach used to objectively identify representative snow-monitoring locations in a forested watershed in the western Oregon Cascades mountain range. We used a binary regression tree (BRT) non-parametric statistical model to classify peak snow water equivalent (SWE) based on physiographic landscape characteristics in an average snow year, an above-average snow year, and a below-average snow year. Training data for the BRT classification were derived using spatially distributed estimates of SWE from a validated physically based model of snow evolution. The optimal BRT model showed that elevation and land cover type were the most significant drivers of spatial variability in peak SWE across the watershed (R2  =  0.93, p value  <  0.01). Geospatial elevation and land cover data were used to map the BRT-derived snow classes across the watershed. Specific snow-monitoring sites were selected randomly within the dominant BRT-derived snow classes to capture the range of spatial variability in snowpack conditions in the McKenzie River basin. The Forest Elevational Snow Transect (ForEST) is a result of this coupled modeling approach and represents combinations of forested and open land cover types at low, mid-, and high elevations. After 5 years of snowpack monitoring, the ForEST network provides a valuable and detailed dataset of snow accumulation, snow ablation, and snowpack energy balance in forested and open sites from the rain–snow transition zone to the upper seasonal snow zone in the western Oregon Cascades.
Las viviendas que pudieron hundir la economía española. La caída del mercado de vivienda y sus consecuencias
Authors: Rodríguez López Julio 
Published: February 2017

Dentro de las numerosas etapas de auge del mercado de vivienda experimentadas por la economía española desde la segunda mitad del pasado siglo, la del periodo comprendido entre 1997 y 2007 ha sido la de mayor alcance. Destacó en la misma la fuerte expansión del crédito destinado a financiar la promoción y la compra de viviendas. La crisis financiera mundial de 2007-2008 provocó una fuerte restricción crediticia en España que frenó las ventas y la nueva construcción residencial. El peso del ajuste recayó sobre todo en las viviendas iniciadas, y resultó moderado el descenso de los precios. Se generó un importante volumen de viviendas nuevas no vendidas. La recesión se prolongó hasta 2013 y ocasionó una significativa destrucción de empleos. El impacto sobre el sistema financiero fue importante, provocando la desaparición de las cajas de ahorros. En 2015-2016 ha tenido lugar una recuperación del mercado de vivienda y de la nueva construcción residencial. Desde la política económica se debe de impedir la creación de nuevas “burbujas” inmobiliarias, que obstaculizan la consolidación de un modelo productivo sostenible en la economía española.
Exploring Korean Heritage Learners' Perceptions of Heritage Language and Learning
Authors: Lee-Smith Angela 
Published: February 2017

ABSTRACTThe present article explores Korean heritage language (HL) and learners from the learners' perspective, and calls for further discussion and/or collaborative work from the field of HL education. This is a survey study that aimed to address seven aspects regarding HL and learning from the learners' perspectives. These included issues of HL learner identity and the benefits and challenges of studying their HL in an academic environment. The qualitative responses were collected through an online anonymous survey of heritage students (N = 22), who took a heritage track intermediate language course at a private university in the United States during the academic years 2014–2016. Findings from the data collected accounted for whom and where the learners are in terms of their HL identity and motivation in learning. This allows Korean language educators to gain insight into HL learners' perceptions and learn which language-learning strategies students find most useful. By the same token, the students' learning goals and self-identified strengths and weaknesses should be reflected in all respects in developing an appropriate HL curriculum and learning materials.

Published: February 2017

In this paper we provide a reference Bayesian framework to a new two-parameter lifetime distribution with increasing failure rate, the complementary exponential geometric (CEG). To this end, we presented some of the main properties of this model and its characteristics related to the reliability analysis. A simulation study is performed to analyse the frequentist properties of credible intervals from the reference posterior distribution among of the standard error and mean square error (MSE) of estimations. The presented methodology is illustrated by the use of a real data set which presents the study of time until the cure of cervix lesions, that are precursors cancer lesions in the cervix. According to to INCA (Cancer National Institute), cervical cancer stands as the fourth cause of death among women in Brazil. Together with breast cancer, it is one of the most common malignancy affecting women worldwide. For this reason, patients must be carefully evaluated for metastatic disease. These data were collected in the Woman Clinic which is sited in Maring\'{a} city (Paran\'{a} State, Brazil).

La contribution des blogues juridiques à la connaissance, à la critique et aux transformations du droit
Authors: Guilhermont Édith 
Published: February 2017

Le blogging juridique est un phénomène tout juste émergent au Québec comparativement à d’autres systèmes juridiques où il est pratiqué de longue date. La blogosphère juridique québécoise compte aujourd’hui une cinquantaine de blogues actifs. Ceux-ci demeurent encore largement méconnus de la communauté juridique, qui ne leur accorde généralement pas de valeur. Ils sont pourtant des outils efficaces de diffusion de la doctrine juridique et de commentaires de jurisprudence, que les juges québécois hésitent d’ailleurs beaucoup moins à utiliser.
Cet article tente de montrer, en s’appuyant notamment sur des exemples étrangers et québécois, dans quelle mesure les blogues juridiques peuvent contribuer, de manière originale, non seulement à la diffusion du savoir juridique, mais aussi à la critique et aux transformations du droit. Pour ce faire, le présent texte propose avant tout de dresser un portrait en instantané de la blogosphère juridique québécoise. Il se poursuit par une discussion au sujet de la nature et de la valeur de la contribution des blogues, et finit par s’interroger sur l’influence, réelle ou potentielle, des blogues juridiques sur les acteurs du droit.
Atmospheric dayglow diagnostics involving the O2(b‐X) Atmospheric band emission: Global Oxygen and Temperature (GOAT) mapping

Published: February 2017

AbstractThe terrestrial dayglow displays prominent emission features from the 0‐0 and 1‐1 bands of the O2 Atmospheric band system in the 760–780 nm region. We present an analysis of observations in this wavelength region recorded by the Space Shuttle during the Arizona Airglow Experiment. A major conclusion is that the dominant product of O(1D) + O2 energy transfer is O2(b, v = 1), a result that corroborates our previous laboratory studies. Moreover, critical to the interpretation of dayglow is the possible interference by N2 and N2+ bands in the 760–780 nm region, where the single‐most important component is the N2 1PG 3–1 band that overlaps with the O2(b‐X) 0‐0 band. When present, this background must be accounted for to reveal the O2(b‐X) 0‐0 and 1‐1 bands for altitudes at which the O2 and N2/N2+ emissions coincide. Finally, we exploit the very different collisional behavior of the two lowest O2(b) vibrational levels to outline a remote sensing technique that provides information on Atmospheric composition and temperature from space‐based observations of the 0‐0 and 1‐1 O2 atmospheric bands.
Identifying potentially induced seismicity and assessing statistical significance in Oklahoma and California

Published: February 2017

AbstractWe develop a statistical method for identifying induced seismicity from large data sets and apply the method to decades of wastewater disposal and seismicity data in California and Oklahoma. The study regions are divided into grid blocks. We use a longitudinal study design, seeking associations between seismicity and wastewater injection volume along time series within each grid block. In each grid block, we find the maximum likelihood estimate for a model parameter that relates induced seismicity hazard to total volume of wastewater injected each year. To assess significance, we compute likelihood ratio test statistics in each grid block and each state, California and Oklahoma. Resampling with permutation and random temporal offset of injection data is used to estimatepvalues from the likelihood ratio statistics. We focus on assessing whether observed associations between injection and seismicity occur more often than would be expected by chance; we do not attempt to quantify the overall incidence of induced seismicity. The study is designed so that, under reasonable assumptions, the associations can be formally interpreted as demonstrating causality. Wastewater disposal is associated with other activities that can induce seismicity, such as reservoir depletion. Therefore, our results should be interpreted as finding seismicity induced by wastewater disposal and all other associated activities. In Oklahoma, the analysis finds with extremely high confidence that seismicity associated with wastewater disposal has occurred. In California, the analysis finds moderate evidence that seismicity associated with wastewater disposal has occurred, but the result is not strong enough to be conclusive.
Low‐mode internal tides and balanced dynamics disentanglement in altimetric observations: Synergy with surface density observations
Authors: Ponte Aurélien L. , Klein Patrice , Dunphy Michael , Le Gentil Sylvie 
Published: February 2017

AbstractThe performance of a tentative method that disentangles the contributions of a low‐mode internal tide on sea level from that of the balanced mesoscale eddies is examined using an idealized high resolution numerical simulation. This disentanglement is essential for proper estimation from sea level of the ocean circulation related to balanced motions. The method relies on an independent observation of the sea surface water density whose variations are 1/dominated by the balanced dynamics and 2/correlate with variations of potential vorticity at depth for the chosen regime of surface‐intensified turbulence. The surface density therefore leads via potential vorticity inversion to an estimate of the balanced contribution to sea level fluctuations. The difference between instantaneous sea level (presumably observed with altimetry) and the balanced estimate compares moderately well with the contribution from the low‐mode tide. Application to realistic configurations remains to be tested. These results aim at motivating further developments of reconstruction methods of the ocean dynamics based on potential vorticity dynamics arguments. In that context, they are particularly relevant for the upcoming wide‐swath high resolution altimetric missions (SWOT).
