Sargsyan, Mariam,신혜령,최정길 한국호텔외식관광경영학회 2023 호텔경영학연구 Vol.32 No.5

In the hotel industry, influencer marketing on social media is a huge issue. This study aims to explore the influencer characteristics that affect consumer behavioral intentions in influencer marketing conducted in the hotel industry. In particular, this study contributes to the existing literature by examining influencer characteristics from the perspective of information sources and utilizing mimetic theory in quantitative research to reveal the mechanisms underlying the relation between the influencer attributes and consumer behavior intentions. To this end, the final 302 data obtained through a survey of Generation Z, the main users of the social media platform Instagram, were analyzed using multiple regression analysis and Sobel's test. As a result, the influencer attributes have a positive and significant impact on consumers' intentions, and mimetic desire partially mediates the relationship. This study is meaningful as it was conducted from the perspective of hotel consumers and is one of the few studies that used mimetic desire as a quantitative variable. This study can provide guidance to other future researchers by providing empirical evidence and insights into how consumers perceive influence characteristics in real-world situations through the variable, mimetic desire. In particular, by comparing influencer attributes and their impact on consumer behavioral intention, it provides effective insights into which influencer characteristics should be considered to enhance the effectiveness of social media marketing when collaborating with influencers for hotel promotion.

Milk Consumption and Prostate Cancer: A Systematic Review

Sargsyan Alex,Dubasi Hima Bindu 대한남성과학회 2021 The World Journal of Men's Health Vol.39 No.3

Prostate cancer is the third most common cancer in men globally, and the most common cancer among men in the United States. Dietary choices may play an important role in developing prostate cancer; in particular, a higher dairy product intake has been associated with an increased risk of developing prostate cancer. The overall positive association between milk con-sumption and the risk of prostate cancer development and prostate cancer mortality has been well documented in multiple epidemiological studies. However, there is limited literature on the association between types of milk, as classified by fat content (skim, low fat, and whole), and the risk of developing prostate cancer. When further examining current state of the literature on this topic, there is a number of epidemiologic studies assessing the relationship between prostate cancer and milk consumption. On the contrary, very few experimental studies explore this topic. Further experimental research may be necessary to examine the relationship between dairy and dairy products consumption and the increased risk of development of prostate cancer. At this time, there are no formal clinical recommendations regarding dairy products consumption for pa-tients who are at risk of prostate cancer development or who have a history of prostate cancer. In this manuscript, we sought to systematically review the existing literature on the association between milk consumption classified by fat content, and the risk of developing prostate cancer. These findings may be useful for the clinicians who provide recommendations for the pa-tients at risk of developing prostate cancer.

이기진,알센바바쟈얀,Tigran Sargsyan,차덕준 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.2

Cadmium-sulphide (CdS) films were prepared on glass substrates by using a chemical bath deposition method. The dependences of the microstructures and the morphologies of CdS films on the annealing temperatures were investigated by using X-ray diffraction, scanning electron microscopy and atomic force microscopy. The change in the sheet resistance due to dierent annealing temperatures was studied by using a near-eld microwave microprobe by measuring the reflection coefficient S11. As the annealing temperature increased from room temperature to 300 ℃, the sheet resistance of the CdS films decreased, the surface roughness and grain size decreased and the surface showed a smoother morphology.

A near-field microwave microscope (NFMM) technique has been used to investigate the photovoltaic effect in solar cells. By measuring the reflection coefficient S11 at an operating frequency near 4.1 GHz, we could observe the photoconductivity changes inside the solar cells. The photoconductivity of the n-type silicon layer in a solar cell increased as the incident light’s intensity was increased due to the carrier motion through the pn junction. The photoconductivity also varied with the incident light’s wavelength. We found good agreement between the variations in the microwave reflection coefficient S11 and the IV characteristics of solar cells for different incidentlight intensities and wavelengths.

Background: With advances in diagnostics and treatment approaches, patients with Hodgkin's lymphoma (HL) in developed countries can nowadays expect to have excellent outcomes. However, information about the characteristics and outcomes in the developing world is very scarce, and this is important given the fact that there are several reports about differences of disease characteristics depending on geographic location and the development level of the country. Materials and Methods: In this retrospective study we assessed the features of 36 adult (${\geq}18$ years old) patients with HL and their diagnosis and treatment and outcomes in the Clinic of Chemotherapy of Muratsan University Hospital of Yerevan State Medical University, Armenia, between 2008-2014. Results: All patients had classic HL and among them 19 (53%) had nodular sclerosis subtype, 8 (22%) mixed cellularity and 9 (25%) lymphocyte-rich. 16 (44.5%) patients were at stage II, 13 (36%) stage III and 7 (19.5%) stage IV. Median follow-up time was 24.5 months (range 1-71 months) and during the whole follow-up period only two relapses (early) were documented and there were no deaths. Twenty-three (64%) patients received a BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen, and 13 (36%) ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) regimen. A total of 25 (69.5%) patients received radiation in addition to chemotherapy. Conclusions: Although the number of patients involved in the study is small and the median follow-up time was just two years, this retrospective study shows that treatment of HL can be successfully organized in a resource-limited setting.

Streamflow, stomata, and soil pits: Sources of inference for complex models with fast, robust uncertainty quantification

Dwelle, M. Chase,Kim, Jongho,Sargsyan, Khachik,Ivanov, Valeriy Y. C.M.L. Publications 2019 ADVANCES IN WATER RESOURCES Vol. No.

<P><B>Abstract</B></P> <P>The scale and complexity of environmental and earth systems introduce an array of uncertainties that need to be systematically addressed. In numerical modeling, the ever-increasing complexity of representation of these systems confounds our ability to resolve relevant uncertainties. Specifically, the numerical representation of the governing processes involve many inputs and parameters that have been traditionally treated as deterministic. Considering them as uncertain introduces a large computational burden, stemming from the requirement of a prohibitive number of model simulations. Furthermore, within hydrology, most catchments are sparsely monitored, and there are limited, heterogeneous types of data available to confirm the model’s behavior. Here we present a blueprint of a general approach to uncertainty quantification for complex hydrologic models, taking advantage of recent methodological developments. We rely on polynomial chaos machinery to construct accurate surrogates that can be efficiently sampled for the ecohydrologic model tRIBS-VEGGIE to mimic its behavior with respect to a selected set of quantities of interest. The use of the Bayesian compressive sensing technique allows for fewer evaluations of the computationally expensive tRIBS-VEGGIE. The approach enables inference of model parameters using a set of observed hydrologic quantities including stream discharge, water table depth, evapotranspiration, and soil moisture from the Asu experimental catchment near Manaus, Brazil. The results demonstrate the flexibility of the framework for hydrologic inference in watersheds with sparse, irregular observations of varying accuracy. Significant computational savings imply that problems of greater computational complexity and dimension can be addressed using accurate, computationally cheap surrogates for complex hydrologic models. This will ultimately yield probabilistic representation of model behavior, robust parameter inference, and sensitivity analysis without the need for greater investment in computational resources.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A general approach to uncertainty quantification with a complex, process-rich model. </LI> <LI> Construction of efficient surrogate models with Bayesian compressive sensing. </LI> <LI> Robust parametric inference using heterogeneous sources of process-scale data. </LI> <LI> Simultaneous characterization of sensitivity of hydrologic outputs to uncertain variables. </LI> </UL> </P>

<P>A cryogenic 7-mm coaxial noise standard at 77.35 K has been designed and constructed. A ferrite composite-matched termination was used as a thermal noise source in the frequency range of 4.5-18 GHz. The noise temperature of the noise standard has been determined by measuring the temperature distribution and attenuation constant of a thermally isolated coaxial line and the attenuation of the output connector. The effective noise temperature has been evaluated to be 84.07-92.21 K with an uncertainty of 1.26-1.67 K (k = 2)</P>
