Authors: Park Sooyeol , Walker Brigham , Anderson Andrew , Shao Yixue , Callison Kevin
Published: February 2023

BACKGROUND

Limited availability of in-person health care services and fear of contracting COVID-19 during the pandemic promoted an increased reliance on telemedicine. However, long-standing inequities in telemedicine due to unequal levels of digital literacy and internet connectivity among different age groups raise concerns about whether the uptake of telemedicine has exacerbated or alleviated those inequities.

OBJECTIVE

The aim of this study is to examine changes in telemedicine and in-person health service use during the COVID-19 pandemic across age groups for Medicaid beneficiaries in the state of Louisiana.

METHODS

Interrupted time series models were used on Louisiana Medicaid claims data to estimate trends in total, in-person, and telemedicine monthly office visit claims per 1000 Medicaid beneficiaries between January 2018 and December 2020. Changes in care pattern trends and levels were estimated around the infection peaks (April 2020 and July 2020) and for an end-of-year infection leveling off period (December 2020). Four mutually exclusive age categories (0 to 17, 18 to 34, 35 to 49, and 50 to 64 years) were used to compare the differences.

RESULTS

Prior to the COVID-19 pandemic, telemedicine services accounted for less than 1% of total office visit claim volume across the age groups. Each age group followed similar patterns of sharp increases in April 2020, downward trends until sharp increases again in July 2020, followed by flat trends thereafter until December 2020. These sharp increases were most pronounced for older patients, with those aged 50 to 64 years seeing increases of 184.09 telemedicine claims per 1000 Medicaid beneficiaries in April 2020 (95% CI 172.19 to 195.99) and 120.81 in July 2020 (95% CI 101.32 to 140.31) compared with those aged 18 to 34 years, seeing increases of 84.47 (95% CI 78.64 to 90.31) and 57.00 (95% CI 48.21 to 65.79), respectively. This resulted in overall changes from baseline to December 2020 levels of 123.65 (95% CI 112.79 to 134.51) for those aged 50 to 64 years compared with 59.07 (95% CI 53.89 to 64.24) for those aged 18 to 34 years.

CONCLUSIONS

Older Medicaid beneficiaries in Louisiana had higher rates of telemedicine claim volume during the COVID-19 pandemic compared with younger beneficiaries.

Published: February 2023

The fabrication, optimization and validation of measurement using a modified carbon paste electrode (CPE) with dibenzo-18-crown-6 were carried out for the determination of paracetamol in commercial products. The pH, dibenzo-18-crown-6 concentration in carbon paste, and scan rate parameters were optimized. Validation of the measurement was observed from linear concentration range, LoD, LoQ, precision, and percentage of the recovery. The result showed that the optimum pH was at 2, the optimum concentration of dibenzo-18-crown-6 in carbon paste was 0.6%, optimum scan rates were 35 mV/s for CPE, and increased to 50 mV/s using modified CPE. The linear concentration range for CPE was obtained at 10-300 µM with LoD and LoQ of 28.88 and 96.28 µM, respectively. Meanwhile, CPE modified with dibenzo-18-crown-6 gave wider linear concentration range at 1–700 µM with LoD and LoQ of 52.36 and 174.53 µM, respectively. The CPE and modified CPE had good precision, with Horwitz ratio values of less than two. The percentage of recovery for two samples with three replicates measurements was obtained (89.81 ± 1.38)% and (108.02 ± 0.42)% for samples A and B, respectively. Dibenzo-18-crown-6 modified CPE was used for the determination of paracetamol in both samples yielding 97–98% compared with the paracetamol composition on its labels.

Fluctuations of pipelines of gas-containing liquids under changing bearing conditions
Authors: Leontiev Yevgeny V. , Travush Vladimir I.
Published: February 2023

The authors deal with the vibration of the pipeline that occurs during the transportation of a gas-containing liquid due to the uneven distribution of gas accumulation along the length of the pipeline, which produces pulsating movements of the center of gravity of the moving liquid, when the conditions for supporting the middle part change. The solution is constructed using the calculation scheme of a beam lying on an elastic foundation described by the Winkler model. To assess the impact on the stress-strain state of the beam of the sudden exclusion of the elastic foundation under the middle part of the beam, the circular frequencies and forms of natural transverse vibrations of the beam that occur in the absence of disturbing forces are determined. The given solution of the problem of vibrations of a pipe, through which a gas-containing liquid is transported, with a change in the conditions of support of the middle part of the beam, can be used to predict the durability of the pipe.
Numerical calculation of bent reinforced concrete elements of rectangular section in the Abaqus software
Authors: Rimshin Vladimir I. , Amelin Pavel A.
Published: February 2023

The calculation of building structures to a large extent began to be performed using automated software systems based on the finite element method. An urgent issue of the widespread use of this type of calculation is the accuracy of the calculation results in comparison with experimental data. In this study, by numerical simulation using the Abaqus software package, the stress-strain state of a bent reinforced concrete element of a rectangular cross section is investigated. Numerical modeling of the element is performed by volumetric finite elements, taking into account the non-linear (actual) state diagram of concrete, described by the model of plastic fracture of concrete with damage (CDP). Reinforcement is specified by rod finite elements, with a combination of elastic properties and metal plasticity model. The loading of the beam element in the model is performed statically with the application of concentrated forces at the centers of the thirds of the design span. As a result of the finite element calculation, the distribution of stresses in concrete and reinforcement according to Mises, deformations of finite elements along the main axes, as well as a model of concrete damage with increasing load were obtained. The obtained results showed a high convergence with the experimental data of testing beams for bending along a normal section, which allows using this algorithm for automated finite element analysis in the design of bending reinforced concrete structures.

Authors: Zhong Xiaoping , Wang Jingjing , Yu Xiaohua
Published: February 2023

Internet celebrities have powerful influence on public opinions and behaviors through affecting their feelings and attitudes. This study proposes a comprehensive framework which consists of individual-social-subjectiveobjective (IS-SO) dimensions to assess the influence of internet celebrities as opinion leaders on public’s subjective values, consumption decisions, perceived cultural changes, and opinions on agribusiness rural development. The IS-SO framework is then applied to analyze an internet celebrity who is named Ms. Li, Ziqi and well-known for her beautiful and influential videos on food and rural issues in China. The findings confirms that the internet celebrities do influence the public’s feelings, opinions, and emotional values at both the individual and societal levels. Specifically, the internet celebrity could change food system by promoting both the sales of related agricultural products and the positive image of rural society as well.

Authors: Eiff M. Patrice , Ericson Annie , Dinh Dang H. , Valenzuela Steele , Nadeau Mark T. , Dickinson W.  Perry , Conry Colleen M. , Martin James C. , Carney Patricia A.
Published: February 2023

Background and Objectives: Training models in the Length of Training Pilot (LOTP) vary. How innovations in training length affect patient visits and resident perceptions of continuity is unknown.
Methods: We analyzed resident in-person patient encounters (2013-2014 through 2018-2019) for each postgraduate year (PGY) and total visits at graduation derived from the Accreditation Council for Graduate Medical Education reports for each LOTP program. We collected data on residents’ perceptions of continuity from annual surveys (2015-2019). We analyzed continuous variables using independent samples t tests with unequal variance and categorical variables using χ2 tests in comparing 3-year (3YR) versus 4-year (4YR) programs.
Results: PGY-1 and PGY-2 residents in 4YR programs saw statistically more patients than their counterparts in 3YR programs. In PGY3, 3YR program residents had statistically higher visit volume compared to 4YR program residents. Visits conducted in PGY4 ranged from 832 to 884. The additional year of training resulted in approximately 1,000 more total patient visits. Most residents in 3YR and 4YR programs rated their continuity clinic experience as somewhat or very adequate (range 86.3% to 93.7%), which did not statistically differ according to length of training.
Conclusions: Resident visits were significantly different at each PGY level when comparing 3YR and 4YR programs in the LOTP and the additional year of training resulted in about 1,000 more total visits. Resident perspectives on the adequacy of their continuity clinic experience appeared to not be affected by length of training. Future research should explore how the volume of patient visits performed in residency affects scope of practice and clinical preparedness.
Challenges Meeting Training Requirements in the Care of Children in Family Medicine Residency Programs: A CERA Study
Authors: Krugman Scott , Hodo Laura Nell , Morgan Zachary J. , Eden Aimee R.
Published: February 2023

Background and Objective: In 2014, the Accreditation Council for Graduate Medical Education (ACGME) implemented numeric requirements for family medicine (FM) pediatric patient encounters. Impact on residency programs is unclear. We aimed to identify any difficulties faced by FM program directors (PDs) meeting these numeric requirements.
Methods: Questions about pediatric training in family medicine residencies were included in a survey of PDs conducted by the Council of Academic Family Medicine Educational Research Alliance (CERA). We performed univariate analysis of the demographic and program characteristics. We then used χ2 tests of independence to test for bivariate associations between these characteristics and our primary outcome: the most difficult ACGME pediatric care requirement to meet.
Results: Most programs reported the hospital as the primary location of training (n=131, 46%) and their family medicine practice (FMP) patient population consisted of over 20% pediatric patients (n=153, 56%). Over 80% of program directors reported challenges meeting FM requirements for the care of children. Challenges meeting pediatric requirements were associated with fewer than 20% FMP patients under 19 years of age (P<.0001), fewer than 50% of core FM faculty caring for sick children (P=.0128), and primary location of pediatric training in a family health center (P=.0006).
Conclusion: Difficulty meeting ACGME requirements for the care of children in FM residency programs is common, especially for programs with fewer than 20% FMP patients under 19 years of age. Further research is needed to determine how best to assure FM resident competencies in the care of children and adolescents.
The tip of the iceberg fibroid effect; when to avoid transcervical resection. The utilisation of 3D pelvic ultrasonography for fibroid mapping.
Authors: Lazaridis Alexandros , Kogeorgos Stylianos , Al-Achmar Nikolaos , Pistofidis George
Published: February 2023

ABSTRACT Our objective is to demonstrate that moderate size type 2-4
fibroids should be removed with laparoscopic myomectomy. The use of 3D
ultrasound imaging to accurately identify size and position of fibroid
is essential, since it guides operative strategy especially when
hysteroscopic evaluation of the submucosal fibroid component may give a
false impression of its size and transcervical resection feasibility. We
present a video demonstration of the diagnostic sequence and then
laparoscopic myomectomy in simple steps. In conclusion, robust
pre-operative assessment is necessary to avoid transcervical fibroid
resections requiring prolonged operative time or multiple sessions.
Effect of a community-based primary healthcare program on adverse pregnancy outcomes in Northern Ghana
Authors: Kanmiki Edmund Wedam , Mamun Abdullah A. , Phillips James F. , O’Flaherty Martin J.
Published: February 2023

Background: Pregnancy complications and adverse birth outcomes
are among the major contributors to poor maternal and child health.
Mothers in remote communities are at higher risk of adverse birth
outcomes due to constraints in access to maternal healthcare services.
In Ghana, a community-based primary healthcare program called the Ghana
Essential Health Interventions Program (GEHIP) was implemented in a
rural region to help strengthen primary healthcare delivery and improve
maternal and child healthcare services delivery. This study assessed the
effect of this program on adverse birth outcomes. Methods:
Secondary household survey data from reproductive-aged women from the
GEHIP project were used in this analysis. Difference-in-differences
regression and logistic regression were used to examine the effect of
GEHIP on adverse birth outcomes and equity in the distribution of
adverse birth outcomes using household wealth index and maternal
educational attainment as equity measures. The analysis involves the
comparison of project baseline and end-line outcomes in intervention and
non-intervention districts. Results: The intervention had a
significant effect in the reduction of adverse pregnancy outcomes
(DiD=-0.043; p-value=0.010). Although disadvantaged groups experience
larger reductions in adverse pregnancy outcomes, controlling for
covariates, there was no statistically significant equity effect of
GEHIP on adverse pregnancy outcomes using either the household wealth
index or maternal educational attainment as equity measures.
Conclusion: GEHIP’s community-based healthcare program reduced
adverse birth outcomes but no effect on relative equity was established.
Factoring in approaches for targeting disadvantaged populations in the
implementation of community-based health programs is crucial to ensuring
equity in health outcomes.

Published: February 2023

Background: Left ventricular ejection fraction (LVEF) has
prognostic value and is used to guide medical treatment and device
implantation. The preferred technique is two-dimensional echo (2DE),
although three-dimensional echo (3DE) is more accurate when compared to
cardiac magnetic resonance imaging. Our study evaluates the agreement
between 2D and 3D LVEF and the potential clinical impact of
disagreements. Methods: Participants ≥50 years were included
from the Copenhagen City Heart Study. Means of difference (MD) between
2D and 3D volumes and LVEF were assessed, Cox regression models were
used to estimate the association between 2D and 3D LVEF <40%
and outcome. 3DE were used as reference. Results: In all 1606
participants were included. Median age was 65.4 (IQR: 57.89‒73.6) and
702 (43.7%) were males. Median follow-up was 5.5 (IQR: 4.72‒6.3) in
which 102 (6.4%) died and 142 (8.8%) experienced a major adverse
cardiovascular event (MACE) and 194 (12.1%) any cardiovascular event.
The MD between 2D and 3D LVEF as the LV deteriorated the LV got (LVEF
<40%, MD: -14.4 (-15.9 ‒ -13.0) vs. LVEF 40-49% -9.2 (-9.8 ‒
-8.7) vs. LVEF >50%, MD: -0.96 (-1.4 ‒ -0.51)). 3D LVEF
<40% was significantly associated with all outcomes (2.85
(95% CI: 1.64‒4.95), (all-cause mortality), 2.71 (95% CI: 1.68‒4.36),
(MACE) and 2.41 (95% CI: 1.68‒4.36) (any cardiovascular event). 2D LVEF
<40% was only associated to MACE 2.69 (95% CI: 1.25‒5.77).
2DE misclassified (defined as ≥10 percentage units of difference between
2D and 3d LVEF) LVEFs in 508 (31.6%) of all exams. Conclusion:
In this population study in low-risk subjects, only 3D LVEF was
associated with excess mortality, whereas 2D LVEF was not.

Authors: Bowman Emma , Bowman Patrick , Weir Tony , Dreyer Craig , Meade Maurice J.
Published: February 2023

Objectives

To quantify the predicted occlusal contact outcomes compared with the clinically achieved occlusal contacts following treatment using the Invisalign aligner appliance.

Materials and Methods

The occlusal contacts of 33 adult patients presenting with a Class I mild-to-moderate malocclusion (spacing <4 mm or crowding of <6 mm) and treated using the Invisalign appliance were measured at the initial, predicted, and achieved stages of treatment by the metrology software Geomagic Control X. Assessed measurements were related to individual teeth and anterior, posterior, and overall contacts.

Results

The mean (standard deviation) difference between the achieved occlusal contact was significantly less than that predicted for overall occlusal contact and posterior occlusal contact (P < .0025). The achieved posterior occlusal contact was also less than pretreatment initial posterior occlusal contact. There was no difference in anterior occlusal contact between the predicted and achieved outcomes (P > .05). The central and lateral incisors displayed no statistically significant difference between the predicted and achieved occlusal contact. The patients with prescribed overcorrection demonstrated a statistically significant difference in predicted occlusal contact compared with those with nonprescribed overcorrection (P ≤ .0025), but no statistically significant difference in achieved occlusal contact.

Conclusions

Treatment by the Invisalign appliance in Class I mild-to-moderate malocclusion resulted in a decrease in posterior occlusal contact. Further research is required to account for the deficiencies between the predicted and achieved clinical outcome related to occlusal contact and to determine the corrective changes required in the treatment protocols.
Mechanism of laser-inducing hierarchical surface structures improving bonding strength of metal-plastic hybrids

Published: February 2023

The mechanism of laser-inducing hierarchical metal surface structures was investigated both experimentally and numerically, providing insights into improving bonding strength of metal-plastic hybrids (MPHs). For this purpose, metal sheets were first treated with the nanosecond pulsed laser to induce surface microstructures, followed by being put into the mold cavity, and jointed with plastic via the injection molding process. Both aluminum and titanium alloys were adopted as the metals and the glass fiber reinforced polyphenylene sulfide was chosen as the plastic material for MPHs. Specifically, laser parameters including the scanning speed, laser frequency, scan repetition, and modulation switch pulse-width were varied to investigate their impact on metal surface microstructure morphology and thus the MPH bonding strength. It is found that although having no clear trend while changing the laser parameters, the MPH bonding strength is strongly dependent on both surface morphology and material type of the metals. Finally, the process was optimized based on observations concerning the laser-inducing mechanism. The titanium alloy surfaces with bumpy morphology facilitated forming microscale mechanical interlocking between the metal and the plastic, leading to enhanced MPH bonding strength.

This study aims to determine the implementation process and the obstacles experienced during online learning. This type of research uses qualitative research with a case study design. Data collection techniques used are observation, interviews and documentation. The results show that 1) the process of implementing online learning has been going well using several media, namely Google Classroom, Google Form, Whatsapp, Zoom and several websites. The process begins with scheduling at the beginning of the semester, implementing the learning process and ending with an evaluation; 2) Constraints that occur during online learning at SMKN 3 Sukoharjo come from internal and external factors. Internal factors are laziness and addiction to playing games. While external factors are limited signal and internet quota used to access learning, lack of teacher knowledge or mastery of IT related to the media used during online learning; 3) The solution applied to internal factors for students is that the teacher always provides motivation at the beginning of the learning process by giving points each student can answer questions from the teacher, the solution that can be given to teachers is to provide training and coaching for teachers related to online learning. Then for external factors, namely providing free quota assistance to students, delivering material through media that does not drain internet quota too much, scheduling that has been neatly arranged so that students can know when to find a place to get a strong signal during the learning process.

Décès liés aux opioïdes dans la région de Kingston, Frontenac,Lennox et Addington en Ontario, Canada : l’épidémie invisible
Authors: Parent Stephanie , Buttemer Samantha , Philpott Jane , Moore Kieran
Published: February 2023

Introduction

Dans la circonscription sanitaire de Kingston, Frontenac, Lennox et Addington (KFLA), les surdoses d’opioïdes constituent une importante cause de décès évitable. La région de KFLA se différenciant des grands centres urbains par sa taille et sa culture, la littérature actuelle sur les surdoses, qui se concentre sur les zones de grande taille, est d’une aide limitée lorsqu’il s’agit de comprendre le contexte des surdoses dans des régions de plus petite taille. Cette étude établit les caractéristiques de la mortalité liée aux opioïdes dans la région de KFLA dans le but d’améliorer la compréhension du phénomène des surdoses d’opioïdes au sein des collectivités plus petites.

Méthodologie

Nous avons analysé les décès liés aux opioïdes qui ont eu lieu dans la région de KFLA de mai 2017 à juin 2021. Nous avons effectué des analyses descriptives (avec effectifs et pourcentages) à l’égard de facteurs conceptuellement pertinents en vue d’une meilleure compréhension du problème : variables cliniques et démographiques, substances en cause, lieux de décès et contexte de consommation (en solitaire ou non).

Résultats

En tout, 135 personnes sont décédées d’une surdose d’opioïdes. Leur âge moyen était de 42 ans, elles étaient en majorité blanches (94,8 %) et de sexe masculin (71,1 %). Elles présentaient fréquemment les caractéristiques suivantes : être incarcéré ou l’avoir déjà été, consommer des substances en solitaire, ne pas recourir au traitement de substitution aux opioïdes et avoir déjà reçu un diagnostic d’anxiété ou de dépression.

Conclusion

Des caractéristiques spécifiques comme l’incarcération, la consommation en solitaire et l’absence de recours au traitement de substitution aux opioïdes ont été repérées dans notre échantillon de personnes décédées d’une surdose d’opioïdes dans la région de KFLA. Une stratégie solide de réduction des méfaits, misant sur la télésanté, la technologie et des politiques progressistes comme l’approvisionnement s
Governance Challenges and Solutions of the Solar Energy for Poverty Alleviation Program in China: The Case of Jinzhai County
Authors: Jin Zhe , Dimiter Ialnazov
Published: February 2023

This paper discusses one of China's targeted poverty alleviation programs, namely the Solar Energy for Poverty Alleviation Program (SEPAP). SEPAP is an important and innovative policy that enables poor households to earn additional income by installing solar panels and selling the generated electricity to the grid. However, there are still some doubts regarding the actual effects of SEPAP. Based on the results of 30 semi-structured interviews with village leaders and local government officials in Jinzhai County, China, we explore in-depth the development stages and the types of SEPAP.

Determining the value of the default as an input variable into the valuation algorithm can be one of the fundamental problems in the valuation of machines. The value of a machine depends on the level of its properties. A machine is a complex system, and the properties of this system are described by several parameters. Increasing the level of these parameters usually significantly affects the production costs. Correct definition of pricing parameters and determination of their price dependencies can lead to improved approaches in the determination of the default value and thus to achieving more credible valuation results. The aim of the contribution was to create a price model for the calculation of the value of the default punching machine depending on its pricing parameters. The advantages of the chosen approach can be seen mainly in the possibilities of data processing and the use of processing outputs for creating practical applications.

In this second of a two-issue special volume comprising papers submitted by friends and colleagues of Bor-ming Jahn to commemorate the occasion of his official retirement, the authors address a number of fundamental issues regarding lithospheric processes. They do this from a variety of perspectives but primarily using state-of-the-art laboratory analyses integrated with detailed field observations; an approach used by Bor-ming throughout his distinguished career. The purpose of compiling these papers is to enhance our knowledge of global-scale processes that have contributed to our understanding of the lithosphere. As such, they provide a lasting tribute to Bor-ming’s outstanding career, motivated by the quest to understand the nature and complexity of both the crust and mantle.

Bor-ming has spent a great deal of his career studying Precambrian geology, accretionary and collisional terranes, ophiolites and the genesis of juvenile crust, and the second part of the special issue is focused on these subjects. The topics in this volume (issue 2, v. 314) cover a broad range of subjects including Precambrian cratonic development, juvenile crust formation in Central Asia, the India-Eurasian collision, ophiolites from Southeast Asia and the crustal evolution of northern Japan.

Proper nutrition along with physical activity promote health and well-being, affect the mental balance of a person, his perception of reality and interpersonal relationships. Automating pro-health behaviors affects behaviors that do not require large amounts of psychoenergetic resources, thus accumulating energy for other life processes. The aim of this article is to analyze the eating behavior and physical activity among employees of corporations with diet based on an externally supplied box diet which is make on their own nutritional choices (they use diet catering meals). The empirical study covered clients of enterprises offering dietary catering. An individual in-depth interview was used as a qualitative research technique. The conclusion to be drawn from the conducted empirical study is that people using externally supplied box diets do not develop healthy eating habits. In the periods when they eat independently, in most cases they do not pay attention to the health, regularity and caloric content of the consumed meals.

Authors: Radziejowska Maria , Niciejewska Marta
Published: February 2023

The use of an essential oil with a therapeutic purpose depends on many conditions. First of all, only substances whose quality meets the guidelines of the modern, current Polish standard PN-EN ISO 9235: 2021-12 (ICS 71.100.60 - Essential oils) and which are classified as essential oils can be used in aromatherapy, i.e. for therapeutic purposes. A very important role in obtaining essential oils of high therapeutic quality is played by the place and method of cultivation of the plant from which the oil is extracted, safety in maintaining the purity of the essential oil during its extraction, and compliance with the special requirement to label the essential oil package. Fragrance, synthetic and natural oils do not meet these requirements and cannot be used for therapeutic purposes.

Nowadays, more and more solar farms are being created in Poland. This is due to the development of PV technology, the appearance of more efficient systems on the market, but also the need for Poland to achieve a 50% share of energy production from zero-emission sources. In designing PV farms, an important issue is the selection of the right angle, but also the distance between individual rows of panels. The article shows the work analysis of the 1 MW PV farm consisting of 2000 units of 500 Wp panels with dimensions of 2220 mm x 1108 mm x 40 mm and a weight of 28.60 kg and 8 inverters SUN2000-105KTL-H1. The panels are arranged in 10 rows in two directions: south and south-west. The analysis was performed for the angles of 10°, 20°, 25° and 30°. The investigation was carried out in order to evaluate the effect of changing the angle of the panels and the distance between the rows on the PV farm efficiency.

Published: February 2023

The production and use of chemicals are continuously increasing worldwide. For example, the global output of chemicals increased approximately 12 times between 1970 and 2020. The burden of disease attributable to exposure to chemicals is significant. World Health Organization estimates that globally, about 5 million deaths and 90 million disability - adjusted life years are attributable to occupational, environmental exposure and management. Public authorities and employers need access to reliable information on chemicals and practical, widely-accepted risk assessment methods in order to effectively control and minimize this threat. To support the management of chemical substances in small and mediumsized enterprises, the UK Health and Safety Executive developed the Control of Substances Hazardous to Health Essentials (COSHH Essentials), a control banding technique that determines the management method by assigning the qualitative work environment characteristics of the enterprises to a hazard and exposure prediction band. Qualitative tools were used for assessing the risk of these chemicals, creating solutions, and implementing control measures in various industrial fields. The present paper synthesizes the results of an extensive research study, dedicated to the evaluation of chemical risks within a Romanian company which has as object of activity the mechanical processing of steel laminates and their treatment by methods of electrochemical deposition of hard chromium / electrochemical nickel plating. The application of the simplified health, safety and environmental risk assessment methodology developed by the French National Security Research Institute (INRS) was considered to be the most appropriate in the preliminary phase of identifying and prioritizing the risks associated with chemicals used in technological processes in selected company. Based on the obtained results, the prevention and protection plan regarding the chemical risks was elaborated, the implementation of which led to the reduction of the workers’ exposure and to the minimization of the probability and severity of the potential consequences.
