Abstract

Since the global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a symptom of the onset of SARS-CoV-2, olfactory dysfunction (OD), has attracted tremendous attention. OD is not only a negative factor for quality of life but also an independent hazard and early biomarker for various diseases, such as Parkinson's and Huntington's diseases. Therefore, early identification and treatment of OD in patients are critical. Many etiological factors are responsible for OD based on current opinions. Sniffin'Sticks are recommended to identify the initial position (central or peripheral) for OD when treating patients clinically. It is worth emphasizing that the olfactory region in nasal cavity is recognized as the primary and critical olfactory receptor. Many nasal diseases, such as those with traumatic, obstructive and inflammatory causes, can lead to OD. The key question is no refined diagnosis or treatment strategy for nasogenic OD currently. This study summarizes the differences in medical history, symptoms, auxiliary examination, treatment and prognosis of different types of nasogenic OD by analyzing the current studies. We propose using olfactory training after 4–6 weeks of initial treatment for nasogenic OD patients with no significant improvement in olfaction. We hope that our research can provide valuable clinical guidance by systematically summarizing the clinical characteristics of nasogenic OD. [ABSTRACT FROM AUTHOR]

Abstract

A lot of poisonous and harmful smoke flow with high temperature will be produced when there is a fire in coal mine underground. The smoke flow will move along mine roadway and have serious danger for underground personnel and devices. So the paper researched movement rule of fire smoke flow of inclined roadway and horizontal roadway: when fire happens in upstream ventilating roadway, fire smoke flow will move downstream of fire area because of functions of fire pressure and buoyancy effect; when fire happens in downstream ventilating roadway, fire pressure is smaller at early stage of fire, so fire smoke flow will move downward along direction of air flow of roadway; with increasing of fire, fire pressure increases constantly, fire smoke flow will move along direction of fresh air flow when air speed of upstream is lower than critical air speed; function of throttling effect is not obvious at early stage of fire in horizontal roadway, fire smoke flow will move along direction of fresh air flow; with increasing of fire, function of throttling effect increases, fire smoke flow will make reverse movement when value of throttling effect is as big as value of ventilating resistance of roadway. The paper has certain guilding function for relief work of fire of roadway.

Abstract

Because change of mine gas concentration is influenced by various factors, so prediction of mine gas emission ca't get some variables. To solve the problem, the paper proposed a prediction method of mine gas emission based on time series. It introduced implementation of using AR model of time series to predict mine gas emission in details. The experiment result showed that error rate of prediction for mine gas emission with the method was 4.3% and the prediction is reliable.

Abstract

In order to predict development status of future safety situation of China's coal industry, a prediction model of simple linear regression for annual death numbers and annual coal production in China's coal industry was established, and the model was used to predict annual death numbers and annual coal production of China's coal industry in three years. The prediction result showed that the model has certain feasibility, which can provide reliable theoretical basis for predicting safety situation of China's coal industry.

Abstract

Smoldering is an oxygen control reaction and its velocity is determined by oxygen supplying rate. Oxygen volume fraction gradient was used to characterize oxygen supplying rate in roadway according to situation that the velocity of wind flowing is very low during smoldering in roadway. Relationship of smoldering velocity and oxygen volume fraction gradient in roadway during lignite smoldering was researched in experiment drawing support of seam smoldering simulating experiment device in roadway and one-variable linear regression technology was used to establish the relation equation of smoldering velocity and oxygen volume fraction gradient in roadway when lignite was smoldering. This relation equation showed that smoldering velocity and oxygen volume fraction gradient took on linear increasing relationship in roadway during lignite smoldering.

Abstract

The theory of dynamic capabilities has made great contribution on explaining enterprises' competitive advantage in strategy management, yet it is rare to use dynamic capabilities theory in marketing research since the competitions in marketing are fierce among companies. In view of the literatures on market orientation and marketing dynamic capabilities, this paper takes service enterprises as the object of study and establishes a new theoretical model. Based on the analysis, (1) we try to identify market orientation in service enterprises in detail; (2) we build the dimensions of marketing dynamic capabilities in service enterprises; (3) we analyze the intrinsic mechanism among market orientation, marketing dynamic capabilities and performances of service enterprises and build a conceptual model with reference to the theoretical framework of "resources — capabilities — performance".
