Summary This study aimed to (i) assess the prevalence and perceived need for treatment of TMD pain, its association with socio‐economic factors gender, in adolescents Xi᾽an, Shaanxi Province, China, (ii) compare gender pain Xi᾽an an age‐matched Swedish population. We surveyed Chinese aged 15 19 years Xi'an, China ( n = 5524), using a questionnaire two‐stage stratified sampling school as unit. The included second‐year students at selected high schools. It also population 17 015) same...

The traditional optimal allocation of water resources mostly focuses on the different supply sources to various types users in life, production, and ecology, cannot reflect differences time space a certain type users. Therefore, this paper constructs refined model for resources, further explores with multiple sources, users, objectives. main steps construction are: (1) Regional gridding. planting structure map land use same resolution study area are selected superimposed them, application...

As a major grain-producing province in China’s Central Plains, Henan Province is severely impacted by drought, making the study of agricultural drought characteristics region crucial. Theil–Sen (Sen) trend analysis, Mann–Kendall (M-K) test and Hurst index method were used to systematically analyze spatial variation based on Temperature Vegetation Dryness Index (TVDI). The results show that: (1) occurs central, northwestern southern an annual scale. situation will continue increase northern,...

In recent years, the increasing frequency of extreme rainfall has exacerbated urban waterlogging, which seriously constrained sustainable development cities. Given problem that impact social information on waterlogging risk is easy to ignore in assessment process, it great significance carry out a comprehensive and identify for prevention control. Based hazard–vulnerability framework, this study comprehensively considers flood disaster hazard socio-economic vulnerability multi-scenario...

This study aims to investigate the antitumor effects of saikosaponin A (SSA) on acute myeloid leukemia (AML) and elucidate its underlying mechanisms, particularly focusing endoplasmic reticulum stress (ERS)-mediated MAPK-p-JNK signaling pathway. The inhibitory SSA proliferation AML cell lines K562 HL60 were evaluated using CCK8 EdU assays. Apoptotic induced by analyzed via flow cytometry. RNA sequencing was performed identify differentially expressed genes enriched pathways. Western blot...

Background and Objectives: Maintaining an appropriate hydration status is crucial for promoting health. Children, who are in the process of growth development, at a higher risk insufficient water intake dehydration. This study aimed to compare among children with different levels dietary sodium intake, explore relationship between status, intake. Methods: In this cross-sectional survey, 155 students grades 4–6 from primary school Binyang County, Nanning, Guangxi, were recruited. Water fluid...

The inclusion measure, the similarity and fuzziness of fuzzy sets are three important measures in set theory. In this article, we investigate relations among measures, sets, prove eight theorems that can be transformed by each other based on their axiomatic definitions, propose some new formulas to calculate sets. These results applied many fields, such as pattern recognition, image processing, neural networks, reasoning, control. © 2006 Wiley Periodicals, Inc. Int J Syst 21: 639–653, 2006.

To determine the impact of oral diseases on everyday life, measures quality life are needed. In complementing traditional disease-based measures, they assess need for care to evaluate health programs and management treatment. reliability validity Oral Impact Daily Performance (OIDP) short-form Health Profile (OHIP-14) among high school students in Xi’an, capital Shanxi province, China. Cross-sectional one-stage stratified random cluster sample using schools as primary sampling unit. Students...

A novel family of numerical integration closed Newton-Cotes quadrature rules is presented which uses the derivative value at midpoint. It proved that these kinds obtain an increase two orders precision over classical formula, and error terms are given. The computational cost for methods analyzed from point view, it has shown proposed formulas superior computationally to same order formula when they reduce below level. Finally, some examples show superiority approach with respect formulas.

Intermittent water supply (IWS) is a relatively common phenomenon across the world as well in rural and peri-urban areas China, though there has been little IWS-focused research from China published to date. IWS consumers typically adopt range of strategies cope with insufficient supply, poor drinking quality, associated inconveniences. In this study, we collected data small-scale utilities households two systems continuous (CWS) systems, comparison groups, Shandong Hubei provinces. Data...

Background: Inadequate access to safe drinking water remains a global health problem, particularly in rural areas. Boiling is the most commonly used form of point-of-use household treatment (HWT) globally, although use bottled low- and middle-income countries (LMICs) increasing rapidly. Objectives: We assessed regional seasonal prevalence HWT practices (including use) low-income areas two Chinese provinces, evaluated microbiological safety associated outcomes, estimated air pollution burden...

In China, achieving rural drinking water safety—meaning access to a safe, affordable, sufficient, and sustainable supply—remains key challenge for government agencies researchers. Using cross-sectional data at the provincial level, in this paper we examine impacts of socioeconomic development on safety China. theoretical framework called Pressure-State-Response (PSR), existing were organized into state pressure indicators. Canonical Correlation Analysis was then used analyze provincial-level...

Drinking water monitoring is essential for identifying health-related risks, as well building foundations management of safe drinking supplies. However, statistical analyses quality data are challenging because non-normal (skewed distributions) and missing values. Therefore, a new method combining index (WQI) with spatial analysis introduced in this paper to fill the gap between collection analysis. Water constituent concentrations different seasons from sources were compared based on WQIs....

In paper [1], the definition of fuzzy set similarity measure and it's application to inference are given. So we introduce set-valued, which is called measure. Fuzzy a generalized measure, axiomatic description given, some examples proposed, meanwhile its pattern recognition shown.
