An intelligent recognition method of factory personnel behavior based on deep learning

The real-time and accurate recognition of abnormal behavior among factory personnel helps enhance their awareness of hazardous environments, thereby reducing the occurrence of accidents. This paper proposes a behavior recognition network based on an attention mechanism and a high-efficiency convolution module. The Bi-Level Routing Attention was introduced to the backbone network, thus enhancing the attention of the recognition network to the target region effectively. The recognition accuracy was further strengthened by improving the neck network based on the ConvNeXt Block module while reducing the model complexity. Thirteen additional recognition models were constructed to enhance the original network from various perspectives. Subsequently, the mean average precision and detection speed of each model were evaluated. Experimental results demonstrated that the detection accuracy of the target recognition network proposed in this paper has been significantly improved, the detection speed meets the real-time requirements, and the comprehensive performance is the most superior compared with other diverse and improved networks. The proposed recognition model can accurately identify a variety of factory personnel's abnormal behaviors in real-time, and it has practical application significance for the problem of personnel safety identification in the factory.

Population Structure and Size of Early Yekaterinburg (1723-1744)

The article is dedicated to the study of the social structure of the population of early Ekaterinburg. The main objective was to investigate individual social groups of the population, as well as the specifics of their formation in a situation of a rapidly growing and developing industrial and administrative center. The research was based on documentary sources of official record-keeping, the most significant of which were the data from local (factory) censuses of residents of the fortress factory in the 1720s — 1740s. Using quantitative analysis methods and social history approaches, the main social groups of the population were identified and characterized. Their numbers were determined, and the history of their formation and employment specifics in the mining industry were analyzed. The conclusions were drawn about the existence of a special social policy by the mining plant administration. It was found that it was aimed not only at maintaining optimal working capacity but also at progressively expanding the group of factory personnel by including representatives of new social groups such as soldiers, recruits, schoolchildren, exiles, and convicts in labor processes. It was shown that by the mid-18th century, Ekaterinburg, founded in 1723, was not inferior to both old and new urban centers in terms of infrastructure development, administrative, industrial, and social institutions, and population composition.

The effect of occupational burnout on Cognitive Failure and General Health in Industrial Workers (Case Study: Iran Tire Factory)

BackgroundHuman resources are the most important organizational resources and play the most important role in the production and productivity cycle. Considering the importance of people's health and the study of their burnout as a possible cause of occupational cognitive failures, this study aimed to investigate the relationship between burnout, cognitive failure, and general health.Participants and procedureA cross-sectional-analytical study was conducted in Iran Tire Factory. The statistical population of this study was 302 personnel who were randomly selected. Data were collected by four valid questionnaires (demographic information, Maslach burnout, cognitive failure, and general health questionnaire). Then data were analyzed using Spss software.ResultsThe results of the analysis revealed that there is a significant and direct relationship between burnout and cognitive failure (P <0.001), and a meaningful inverse relationship was found between cognitive failure and physical health (P = 0.022). The other results showed that emotional exhaustion and depersonalization dimensions are significantly associated with cognitive failure(P <0.001, p=0.016).ConclusionsAccording to the results of this study, burnout causes cognitive failures among factory personnel and on the other hand, cognitive fractures affect the physical health of individuals and lead to deterioration of physical health, which in turn can reduce a person's performance and reduce work efficiency.

The Impact of Occupational Noise on Hypertension Risk: A Case-Control Study in Automobile Factory Personnel.

BackgroundMany epidemiological studies have investigated the relationship between occupational noise and hypertension, but with conflicting findings. This study aimed to assess the relationship between occupational noise exposure and the risk of hypertension.MethodsA case-control study was conducted to explore hypertension predictors, and then sensitivity analysis was performed based on propensity score matching (PSM). Data were collected from participants' annual physical examinations and occupational noise exposure measurements. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression analysis. A restricted cubic spline (RCS) function was used to fit the dose-effect relationship.Results500 cases and 4,356 controls were included in the study. Multivariate logistic regression showed that an increase in the level of occupational noise [range 68–102 dB(A)] of 1 dB(A), corresponded to an increase in hypertension risk of 8.3% (OR: 1.083, 95% CI: 1.058–1.109). Compared to the first quartile, the risk of hypertension in the fourth quartile was 1.742 (95% CI: 1.313–2.310). After applying PSM to minimize bias, we obtained a population of 500 cases and 1,000 controls. Noise level was significantly associated with the risk of hypertension. In addition, the RCS curve showed the risk of hypertension was relatively stable until a predicted noise level of around 80 dB(A) and then started to increase rapidly afterward (Pnonlinear = 0.002).ConclusionsOccupational noise exposure was significantly associated with hypertension risk and there was a positively correlated dose-response relationship.

Development of renewable, densified biomass for household energy in China

Recent national strategic plans in China have set renewable energy targets for rural household energy programs, including those that advance the production of densified biomass fuels (e.g. pellets, briquettes) for use in household cooking and heating stoves. There is presently very little information on potential barriers to the successful development of densified biomass for household cooking and heating in China, but such knowledge may be informative in settings that aim to replace unprocessed coal and other polluting fuels with renewable, cleaner-burning energy sources. We designed a case study to coordinate data-gathering efforts at rural field sites in southwestern Sichuan province and northeastern Jilin and Heilongjiang provinces, where production of densified biomass fuels is under development for household end-users. We conducted interviews with factory personnel, local administrative leaders, and sector experts involved in the production and distribution of densified fuel, including pellets and briquettes, for household use. Results from our qualitative textual data analysis yielded several recommendations for improving development of densified biomass fuels for household end-use. These included reducing heterogeneity of feedstocks, increasing financial support for operational costs (e.g. collection, transport, and storage of raw materials; storage and distribution of final products), improving household perceptions of and subsequent demand for densified biomass fuels, and increasing enforcement of national and provincial policies banning the use of coal and open-field biomass burning. Collection and storage of raw materials and the final densified fuel product were consistently noted as critical challenges to scaling up production at all three sites. Finally, the perspectives of factory managers and local village administrators that we present also indicated that production of densified biomass fuels would most likely be more successful and reproducible in places where national-level policies are viewed as obligatory.

A synthetic method for atmospheric diffusion simulation and environmental impact assessment of accidental pollution in the chemical industry in a WEBGIS context.

The chemical industry poses a potential security risk to factory personnel and neighboring residents. In order to mitigate prospective damage, a synthetic method must be developed for an emergency response. With the development of environmental numeric simulation models, model integration methods, and modern information technology, many Decision Support Systems (DSSs) have been established. However, existing systems still have limitations, in terms of synthetic simulation and network interoperation. In order to resolve these limitations, the matured simulation model for chemical accidents was integrated into the WEB Geographic Information System (WEBGIS) platform. The complete workflow of the emergency response, including raw data (meteorology information, and accident information) management, numeric simulation of different kinds of accidents, environmental impact assessments, and representation of the simulation results were achieved. This allowed comprehensive and real-time simulation of acute accidents in the chemical industry. The main contribution of this paper is that an organizational mechanism of the model set, based on the accident type and pollutant substance; a scheduling mechanism for the parallel processing of multi-accident-type, multi-accident-substance, and multi-simulation-model; and finally a presentation method for scalar and vector data on the web browser on the integration of a WEB Geographic Information System (WEBGIS) platform. The outcomes demonstrated that this method could provide effective support for deciding emergency responses of acute chemical accidents.

ANALYSIS OF EARLY-NINETEENTH-CENTURY MUSCOGEE CREEK FUR TRADE AT A UNITED STATES FACTORY STORE

We conducted an analysis of economic transaction records from the Fort Wilkinson Factory Store in central Georgia in an attempt to understand trade behaviors by the Muscogee Creek people of the southeastern United States. Between February 4, 1804, and November 29, 1806, factory personnel recorded 2,168 trade transactions at Fort Wilkinson. During this period, 38,226.5 deerskins and skins, 482 hides and rawhides, and 569 furs entered the fort. In exchange for these items, the Creek Indians primarily received cloth, followed by manufactured items such as kettles, gun supplies, and consumable groceries. We analyze the month-by-month exchange trends and compare the trade-good assemblages to archaeological sites that represent Creek occupations that date to the same time period in Georgia and Alabama. Further, we assess the biases of the data and interpret the data in relation to existing historical and archaeological studies of the Muscogee Creek people.

CaneInfo: A User-Centered Website for Cane Growers and Cane Development Personnel

Sugarcane production technologies have been delivered through different media over the years, in countries such as India. In the early years, radio had played a significant role in the transfer of technology process, followed by Television. Farm magazines and newspapers too have played a role throughout. In the 1990s, the Internet arrived and has interconnected the communities to an unimaginable extent. The extension educators in the developed countries had been quick to discover the power of posting information on the web where thousands of people can download and view this information. The commitment of Government of India is that by the end of 2012, every single panchayat will be connected with high-speed broadband access. It is imperative therefore for the sugarcane extension system operating across the states, to shift from being predominantly print-focused, in line with the demands and requirements of the information age. Keeping this in view, the Sugarcane Breeding Institute of the Indian Council of Agricultural Research, has taken the lead and developed a user-centered and database-driven website, CaneInfo (available in www.caneinfo.nic.in) to cater to the needs of the stakeholders in sugarcane farming. The paper describes how CaneInfo was developed systematically, taking into account the information needs of the target audience, and how it was evaluated before hosting. Finally, explaining various features of the website, the paper dwells on the role CaneInfo is expected to play, in disseminating research—based and timely information to the sugarcane growers and sugar factory personnel, in its quest to make sugarcane production more remunerative in the country.

Cancer mortality among Chinese chrysotile asbestos textile workers

To determine mortality associated with exposure to chrysotile asbestos, a cohort of asbestos workers from an asbestos textile factory in China was followed prospectively from 1972 to 2008. A total 577 workers were successfully followed, achieving a follow-up rate of 98.5% over 37 years. Employment data and smoking information were obtained from factory and individual workers. Vital status was ascertained from factory personnel records and the municipal death registry. Workers were categorized into high, medium and low exposure groups in terms of their job titles and workshops. Follow-up generated 17,508 person-years, with 259 deaths from all causes, 96 all cancers and 53 lung cancers and 2 mesotheliomas. The highest cancer mortality was observed in the high exposure group, with 1.5-fold age-adjusted mortality from all cancers and 2-fold from lung cancer compared to the low exposure group. Age and smoking adjusted hazard ratio in the high exposure group was 2.99 (95%CI, 1.30, 6.91) for lung cancer and 2.04 (1.12, 3.71) for all cancers. Both smokers and nonsmokers at the high exposure level had a high death risk of lung cancer, with a clearer exposure-response trend seen in smokers. This study confirmed increased mortality from lung cancer and all cancers in asbestos workers, and the cancer mortality was associated with exposure level.

Modelling manufacturing process using a modified IDEF0 framework: a case study of a car door manufacturing plant

This research paper explores a modified framework for the modelling of a manufacturing process. A modified IDEF0 model has been followed as the methodology since it can ease access to decision details from an unstructured database. From the case study, the concepts enable to build a full information model for decision-making in a manufacturing system to support basic production activities (operations, transport, inspection, etc.). The results obtained after the simulation of the modified model was found to be remarkable when it was verified with factory personnel.

2A1-D12 腰部補助用マッスルスーツの開発

The use of the McKibben artificial muscle has opened the way to the introduction of "muscle suits"-compact, lightweight, reliable, wearable "assist-bots" enabling factory personnel to lift and carry weights greater than conventionally possible. Since low back pain is one of the most serious issues for the manual worker, we focus on developing sacroiliac support. In this paper, the concept, a new mechanical structure and effect of the sacroiliac support system is shown. From the experimental result to keep forward tilting posture with load indicates our system is very effective for keeping forward tilting posture and it becomes clear that more than 75% reduction of muscular power is realized.

Muscle Suit Development and Factory Application

Technological progress has liberated most industrial personnel in developed nations from heavy lifting tasks. Such work remains largely unchanged, however, in the fields of agriculture, manufacturing, and construction, among others. Such tasks are an important issue due to their potential for triggering work-related musculoskeletal disorders. The use of the McKibben artificial muscle has opened the way to the introduction of “muscle suits” - compact, lightweight, reliable, wearable “assist-bots” enabling factory personnel to lift and carry weights greater than conventionally possible.

Skills for the 21st Century Supervisor: What Factory Personnel Think

The study reported here is an attempt to fill a void in research regarding the opinions of people who actually work on the shop floor. In addition to providing historical and modern perspectives on the supervisory profession, its primary contribution is a prioritized set of 30 supervisory skills, synthesized from extant literature in the area of human performance. Factory personnel believe these skills are what are needed for leading and improving employee performance in the complex manufacturing environment of the 21st century. Using Likert-type rating scales to serve as the data collection instrument, subject groups (sorted by employees, supervisors, and managers) representing manufacturing firms in the Waterloo/Cedar Falls, Iowa, metropolitan areas were asked to rate the importance of each of the 30 skills. Three data analyses were conducted: a Pareto analysis to determine which categories and skills were most important, a comparative analysis to measure how the groups differed in their ratings, and a one-way analysis of variance F-test to determine significant differences between the mean ratings of the groups. Where significant differences were discovered, apost hoc test was also conducted to assess pairwise differences. This study was successful in identifying a Taxonomy of Supervisory Skills for improving employee performance. Although the subject groups rated all 30 skills relatively high, six specific skills were found to be most important. In the rating of nine particular skills, significant pairwise differences were discovered.

RE: “OCCUPATIONAL RISK FACTORS FOR ESOPHAGEAL AND STOMACH CANCERS AMONG FEMALE TEXTILE WORKERS IN SHANGHAI, CHINA”

The authors evaluated associations between occupational exposures in the textile industry and the risks of esophageal cancer and stomach cancer. The authors conducted a case-cohort study nested in a cohort of female textile workers in Shanghai, China. One hundred and two workers with incident esophageal cancer and 646 workers with incident stomach cancer diagnosed between 1989 and 1998 were compared with an age-stratified reference subcohort (n = 3,188). Work histories were ascertained for all study subjects from factory personnel records or interviews. Exposures were reconstructed for chemicals and dusts by linking work history data with a job-exposure matrix developed for the Shanghai textile industry. Hazard ratios and 95 percent confidence intervals were calculated with Cox proportional hazards modeling adapted for the case-cohort design. Risk of esophageal cancer was associated with long-term (> or = 10 years) exposure to silica dust (hazard ratio = 15.8, 95% confidence interval: 3.5, 70.6) and metals (hazard ratio = 3.7, 95% confidence interval: 1.9, 7.1). Cumulative exposure to endotoxin, a contaminant of cotton dust, was inversely related to risks of both esophageal cancer (p-trend = 0.01) and stomach cancer (p-trend < 0.001) when exposures were lagged 20 years. Endotoxin has not been previously reported to be a protective factor for either stomach cancer or esophageal cancer and therefore warrants further study.
