“…Gas chromatography coupled to mass spectrometry (GC-MS) was mainly applied in targeted detecting of fatty acids or polar lipid components in wheat [25,26]. Volatile compounds of wheat samples have drawn much attention, and they have been applied in wheat geographical discrimination using the GC-MS approach [27]. Finnie and colleagues quantitatively characterized the polar lipid components of different layers of wheat fractions based on liquid chromatography-mass spectrometry (LC-MS) techniques [28].…”

Wheat is the staple food for the world’s major populations. However, chemical characters of geographically authentic wheat samples, especially for the lipids, have not been deeply studied. The present research aimed to investigate lipid compositions of Chinese wheat samples and clarify the major markers that contribute to the geographical differences. A total of 94 wheat samples from eight main wheat-producing provinces in China were evaluated to differentiate their lipid compositions. Based on the data collected from ultra-high-performance-liquid-chromatography tandem time-of-flight mass spectrometry (UPLC-Q/TOF MS), an optimized non-targeted lipidomic method was utilized for analyses. As the results, 62 lipid compounds, including fatty acids, phospholipids, galactolipids, triglycerides, diglycerides, alkylresorcinol, and ceramide were tentatively identified. Partial least squares discriminant analysis (PLS-DA) demonstrated a more satisfying performance in distinguishing wheat samples from different origins compared with principal component analysis (PCA). Further, the abundances of triglycerides and glycerophospholipids with more unsaturated fatty acids were found greater in wheat samples from northern origins of China, while more glycolipids and unsaturated fatty acids arose in southern original wheat samples. These findings describe the lipid profiles of wheat samples in China and could contribute to the quality and safety control for the wheat flour products.

This research aims to analyze the relationship of age, sex, years of work, nutritional status and work shifts to work fatigue. This research is a quantitative observational analytic study with an analytic cross-sectional study design and a sample size of 60 people. Primary data were collected by direct observation, interviews with the KAUPK2 questionnaire and measurement of Lassidaya L77. The results of bivariate analysis showed a relationship between age and nurse work fatigue (p = 0.026). There was no gender relationship (p = 0.552), years of service (p = 0.104), nutritional status (p = 0.288) and work shift (p = 0.132) with work fatigue. Arifin Achmad Hospital (p = 0.009) POR 12,199 (95%: 1,847 - 80,575). Counfonding work shifts with tenure. There is no relationship between sex and nutritional status with the incidence of work fatigue. Nutritional status (p = 0.571), POR 1.458 (95%: 0.395 - 5.379). Nutritional status (p = 0.866) 1.062 POR (95%: 0.527 - 2.140). The age variable was not included in the multivariate analysis because it was homogeneous. From the results of the analysis it was concluded that the working period ≥ 10 years affects work fatigue compared to ten years <10 years.

“…For example, Lim Dong Kyu et al [10] used untargeted metabolomics approaches to analyze the geographical origin of rice and proposed a phospholipid-based discrimination method. For example, Lim Dong Kyu et al [11] successfully established a classification model based on linear discriminant analysis by gas chromatography to discriminate the geographic origin of Chinese winter wheat. This model could be used to distinguish between geographical origin and variety, but the accuracy rate for origin identification was low.…”

Soybeans have the characteristics of balanced amino acid species and high nutritional value. In this paper, the feasibility of the identification soybean from three typical origins (Argentina, the United States and China) by interval partial least squares (iPLS) optimized terahertz (THz) spectroscopy combined with chemometrics was investigated. Firstly, the THz frequency-domain spectrum was optimized using iPLS. Then, 168 soybean samples were selected as the correction set, and soybean origin identification models were respectively built using the extreme learning machine (ELM), genetic algorithm support vector machine (GA-SVM), and artificial bee colony algorithm support vector machine (ABC-SVM) combined with 8 pre-processing techniques. Finally, the models were verified through 57 samples of the test set and the comprehensive identification accuracy rate of the ABC-SVM model reached 94.74%. The experimental results showed that after iPLS optimization and appropriate pre-processing technique, THz spectroscopy and chemometrics could accurately identify the origin of soybean. INDEX TERMS Terahertz, origin, pre-processing technique, iPLS, chemometrics I. INTRODUCTION Soybeans from different origins have large differences in appearance, color, nutritional value, and internal chemical composition [1]-[2]. According to the database of the Food and Agriculture Organization of the United Nations, the United States and Argentina are among the top three soybean producing countries in the world in 2019. At the same time, they are also the main sources of imported soybeans for China.
