Published: October 2024

This study aimed to perform lactose hydrolysis using free and immobilised β-galactosidase in cow and sheep milk with different fat levels, followed by lactulose synthesis through the isomerisation of glucose to fructose using immobilised glucose isomerase. There was no significant difference (P > 0.05) in lactose hydrolysis (>95%) using the free enzyme in the different types of milk. In contrast, significant differences were observed for the hydrolysis of whole cow milk (WCM) and skimmed cow milk (SCM) with the immobilised enzyme (IE). WCM required a longer hydrolysis time (43 h). Thus, the fat content may have affected the lactose hydrolysis of bovine milk with immobilised β-galactosidase. No difference was observed for whole sheep milk and skimmed sheep milk hydrolysed by IE, possibly due to the presence of smaller fat globules, which did not affect the lactose hydrolysis. No significant differences were observed for lactulose synthesis in whole milk from the different species evaluated. The lactulose synthesis in cow and sheep milk by the enzymatic route may be a promising alternative, though further studies are required to optimise the production of this prebiotic in situ.

Published: October 2024

This article analyses the impact of the coronavirus pandemic on the social problems and poverty of the elderly. Quarantine measures caused increased isolation, loneliness, psychological problems and limited access to medical care, which negatively affected their physical and mental health. The demographic shift towards an aging population presents seniors with complex challenges, including the struggle to meet basic needs and live on the poverty line. These related problems, associated with a lack of attention from the environment, have a negative impact on their quality of life. In the article, we analyse the state of poverty development, based on current statistics. The current isolation, loneliness and loss of independence are intertwined with low income and the possibility of institutionalization, which has increased with the advent of the pandemic situation and the economic crisis.

Authors: Diomidov Ivan
Published: October 2024

Information systems are applied in the forestry sector to address a wide range of tasks. The process of their development has led to the emergence of a heterogeneous set of systems and methods. The aim of the research is to determine their further development and formulate a work plan. To achieve this, the author conducted a review of publications on the subject, including both theoretical works and existing systems and processing methods. The guiding principle of selection was to provide a comprehensive and thorough coverage of the subject area. The methods were classified according to the tasks they solve and presented in logical order, starting from the widely used ones and ending with experimental ones. As a result, it was found that analytical methods are developing significantly, which will lead to the emergence of new data models in the future. Geographic information systems, specifically distributed network-based ones, are also evolving. The problem of modeling forest vegetation is generally part of the task of modeling ecosystems as a whole. The author concluded that integrated information systems are a relevant direction for the industry. A project for further development was proposed, decomposing the task of building information systems. The author sees the forest inventory system as the main system, upon which all other systems depend and can be presented as separate services. The research contributes to the development of theoretical concepts of forest information processing systems. It is useful for specialists and researchers in the field of forestry, as well as developers of specialized software.

Authors: Burova Nadezhda , Osintseva Mariya
Published: October 2024

Biological reclamation is used to restore technogenically disturbed landscapes. Plant characteristics are important when choosing a plant assortment for the restoration of degraded areas. The purpose of this work was to study the principles and methods of creating artificial vegetation cover on disturbed industrial lands. Before carrying out biological reclamation, the surface was finished and a layer of potentially fertile soil layers with a capacity of at least 1 m and a fertile soil layer with a capacity of at least 0,5 m was applied. Before starting work, the quality of the seed material and its value were determined. Soil improvers (sapropel, latex, microorganisms, cellulose mulch) and biologics (TOP organic, complex of rhizospheric bacteria, hydrogel) were used for planting herbaceous and woody shrubby plants. After carrying out the hydraulic sowing activities, field germination of the seed was monitored every 10 days. Aerial photography was performed with an RGB camera using unmanned aerial vehicles of the DJI Phantom 4 Pro+ model with an on-board Global Navigation Satellite System receiver installed. It was found that the use of a biological product based on a complex of rhizospheric bacteria activated the processes of seed germination in experimental plots. Such activation made it possible to obtain productive bushiness of perennial crops in the early stages, due to which the area of vegetation covering the experimental site increased. The addition of hydrogel and TOP organic with a weight of 2 kg also had a positive effect on seed germination and plant survival. A comparative analysis of all experimental parameters revealed that the most effective projective coating of the site was obtained with the combined use of hydrogel and the preparation TOR-organic. At the same time, a further increase in the mass fraction of hydrogel in the substrate does not significantly affect the result of the creation of artificial vegetation cover on disturbed industrial lands.

Authors: Vadde Ramakrishna , Gupta Manoj Kumar
Published: October 2024

Machine learning (ML) holds great promise in advancing risk prediction and stratification for neuroblastoma, a highly heterogeneous pediatric cancer. By utilizing large-scale biological and clinical data, ML models can detect complex patterns that traditional approaches often overlook, enabling more personalized treatments and better patient outcomes. Various ML techniques, such as support vector machines, random forests, and deep learning, have shown superior performance in predicting survival, relapse, and treatment responses in neuroblastoma patients compared to conventional methods. However, challenges like limited data size, model interpretability, data variability, and difficulties in clinical integration hinder broader adoption. Additionally, ethical concerns related to bias and privacy must be addressed. Future work should focus on improving data quality, enhancing model transparency, and conducting thorough clinical validation. With these advancements, ML has the potential to revolutionize neuroblastoma care by refining early diagnosis, risk assessment, and therapeutic decision-making.

Published: October 2024

Key Points

Low-dose acetazolamide reversibly lowered GFR in persons with type 1 diabetes mellitus, suggesting a possible role in relieving glomerular hyperfiltration.

Low doses of acetazolamide were well tolerated in persons with type 1 diabetes.

Background

Sodium-glucose cotransporter-2 inhibitors (SGLT2is) lower the risk of kidney failure in persons with type 2 diabetes. The presumed mechanism of action is through greater delivery of sodium to the distal tubule and activation of tubuloglomerular feedback, which lowers GFR and intraglomerular pressure. SGLT2is are not approved for use in persons with type 1 diabetes because of the risk of diabetic ketoacidosis. Acetazolamide, a proximal tubule diuretic, delivers more sodium to the distal nephron and may activate tubuloglomerular feedback in a similar way to SGLT2is without a higher risk of diabetic ketoacidosis. The kidney effects and safety of acetazolamide in persons with type 1 diabetes have not been well studied.

Methods

We conducted a dose-escalation trial to determine the effects of three dosages of oral acetazolamide (62.5, 125, and 250 mg, all twice daily) in 12 persons with type 1 diabetes. Participants were treated for 2 weeks, followed by a 2-week washout period before exposure to the next dosage level. Blood and urine chemistries, as well as iohexol-measured GFR, were assessed before and after each treatment interval. We aimed to identify a dose that maximized measured GFR reductions while minimizing adverse effects.

Results

The mean age was 46±17 years, 100% were White, and 75% were female. The mean measured GFR was 89±18 ml/min per 1.73 m2 at baseline. Acetazolamide reduced measured GFR by 15% (95% confidence interval [CI], 9 to 21), 14% (95% CI, 7 to 21), and 15% (95% CI, 10 to 21) after 2 weeks at the 62.5, 125, and 250 mg twice-daily dosage levels, respectively. The measured GFR reduction was fully reversed after each 2-week washout. Serum bicarbonate was reduced by 2.3, 4.2, and 4.4 mEq/L with escalating doses, and no episodes of hypokalemia (<3.5 mEq/L) were observed.

Conclusions

Among persons with type 1 diabetes and preserved kidney function, acetazolamide caused an acute, reversible reduction in measured GFR without effects on glucose metabolism.

Contrastive vowel length and segment duration in production and perception in Djambarrpuyŋu
Authors: Jepson Kathleen
Published: October 2024

This paper deals with segment duration and phonological length in production and perception in the Australian language Djambarrpuyŋu. It provides an acoustic phonetic account of vowel and consonant duration to ascertain whether the phonetic evidence supports the analysis of contrastive vowel length in production. From a perception perspective, how Djambarrpuyŋu listeners use segment duration in categorising a pair of words that are proposed to be phonologically distinct by vowel length is tested. In the production study, phonemically long vowels were found to be approximately twice as long as short vowels, and consonants following short vowels were somewhat longer than when following long vowels, though the patterns were affected by syllable structure. In perception, listeners relied on vowel duration to distinguish between words that differed phonologically by vowel length, though consonant duration did influence the perceptual crossover point between words. The results are considered to address the questions of what evidence supports the vowel length contrast in Djambarrpuyŋu, and identifying the underlying mechanisms that result in the observed segment duration patterns.

Are Manufacturing Jobs Still Good Jobs? An Exploration of the Manufacturing Wage Premium
Authors: Bayard Kimberly , Cajner Tomaz , Gregorich Genevieve , Tito Maria D.
Published: October 2024

This paper explores the factors behind the disappearance of the manufacturing wage premium—the additional pay a manufacturing worker earns relative to a comparable nonmanufacturing worker. With substantially larger declines across union members, we quantify the role of unionization by exploiting the heterogeneity in membership status across manufacturing industries. We find that the decline in union membership explains more than 70 percent of the decline in the wage premium since the 1990s for union members but does not affect nonunion premia. Our findings suggest that the erosion of “good” manufacturing jobs has contributed to the increase in overall wage inequality.

Published: October 2024

This paper examines labor markets across Latin American countries, revealing substantial differences in unemployment, informality, and worker transitions. Using surveys from eight countries, we construct comparable statistics on employment stocks and mobility patterns. Notable cross-country differences emerge, with economies mostly clustered into high unemployment-low informality or low unemployment-high informality groups. Transition probabilities and directional flows also vary significantly. We highlight the importance of using country-specific parameters when simulating labor market and aggregate outcomes. Finally, we compare our main results with those by sex and education groups.

Authors: Nagy László
Published: October 2024

Minden állam hivatalos politikájának szerves részét képezi a kül-, a biztonság- és a védelempolitika, amelyekből kettőnek önálló minisztériuma van a legtöbb országban. A biztonságpolitikai funkciók döntő többsége megoszlik a két minisztérium és a titkosszolgálatok között. Oroszországban tetemes számú biztonságpolitikai dokumentum rögzíti a biztonsággal kapcsolatos hivatalos állásfoglalást, ezen belül a biztonsági kockázatokat (veszélyeket, fenyegetéseket) és az állam reagálását ezekre a kihívásokra. Az orosz-atlanti és ezen belül az orosz-amerikai kapcsolatok alakulása jól tükröződik a biztonságpolitika változásaiban.

Staphylococcus epidermidis, a coagulase-negative staphylococcus, is a prevalent skin commensal that has increasingly been recognized as a significant pathogen, particularly in hospital environments, where it is associated with device-related infections. The emergence of multi-drug resistance and its ability to form biofilms complicate the clinical management of infections caused by this organism, posing a growing public health concern. This study aimed to investigate the nasal carriage of S. epidermidis among healthy young individuals and to analyze its antibiotic resistance patterns, resistance genes, and biofilm formation capabilities. Nasal swabs were collected from 40 undergraduate students at Mahasarakham University, Thailand, aged between 20 and 22 years. A total of 38 isolates were confirmed as S. epidermidis through both phenotypic and molecular characterization. Antibiotic susceptibility testing demonstrated resistance to various classes of antimicrobials, including beta-lactams, macrolides, and tetracyclines. Notably, five isolates exhibited methicillin resistance S. epidermidis (MRSE). Resistance genes, such as mecA, ermA, tetM, tetL, and tetK, were identified across the isolates, contributing to the observed resistance profiles. Biofilm formation assays revealed that most isolates displayed weak to moderate biofilm formation, with only one isolate demonstrating strong biofilm-forming capacity. Genetic analysis indicated a significant correlation between biofilm formation and the presence of the icaA gene, which is crucial for biofilm production. This study suggests the necessity for ongoing surveillance of nasal carriage of S. epidermidis to enhance understanding of its role in the dissemination of antimicrobial resistance and biofilm-associated infections, particularly within healthcare settings.

Authors: Que Yixiang , De La Hera Teresa , Jansz Jeroen
Published: October 2024

This study delves into the representation of intangible Chinese cultural heritage in Chinese mobile games. Nowadays, even with huge economic potential, Chinese mobile games are still faced with negative comments, especially from parents. To develop their reputation, Chinese mobile games have portrayed considerate Chinese intangible cultural heritage (ICH). The representation of cultural heritage in video games has been a subject of discussion for a long time, while console and computer games and tangible cultural heritage have been at the centre of academic studies. Hence, we strived to investigate how Chinese ICH is depicted in Chinese mobile games. A thematic analysis was conducted on data collected through analytical gameplay of 30 Chinese mobile games selected from Apple’s App Store and the Chinese TapTap platform. Our analysis indicates that Chinese ICH is represented in Chinese mobile games to fulfil the persona of game characters, to create a more engaging and immersive game world experience, to provide more intense combat moments, to offer visually enjoyable virtual goods, and to deliver culturally driven updates during traditional festivals. Among the various forms of Chinese ICH, Chinese traditional craftsmanship is found to be used most frequently because of the huge effort it requires to be mastered, which could be educational to players. Theatrical traditions were found to be depicted in most game elements because they combine visual, audio, and motional elements. Lastly, folk and classical literature is portrayed in Chinese mobile games to provide a narrative resource that culturally resonates with players.
Effect of abutment geometry on the microgap size in a taper connection
Authors: Kirsanova Viktoriya V. , Furtsev Taras V. , Lukin Roman S.
Published: October 2024

Background: For implant-supported restorations, clinicians use both original and non-original abutments, which are widely available in today’s dental market. The finite element analysis previously conducted by the authors revealed that the microgap size in a taper connection depends on the selected abutment and affects the state of the marginal bone surrounding the implant.
Aim: To determine the distinguishing factor between original and non-original abutments that has the greatest impact on the microgap size in a taper connection during masticatory force modeling.
Materials and methods: The study used Straumann Bone Level (BL), BioHorizons Tapered Internal, and NobelParallel Conical Connection (CC) implants and standard abutments, as well as non-original ADM Dental abutments. Before conducting a serial computational experiment, the geometric parameters of the samples were manually measured. In the first stage of the study, four main factors were identified: screw material, abutment material, screw geometry, and abutment geometry. The calculations were based on the authors’ earlier research findings and were performed using finite element modelling with the Mechanical module of the ANSYS Workbench software.
The NeoScan N80 microtomography system was used in the second stage of the study. Moreover, the microgap size and length of cone generatrixes between the components were measured to better understand the geometry of the samples. The results were processed using the DataViewer and CTVox (Bruker Micro-CT) software.
Results: The abutment geometry had the greatest impact on the microgap size of a taper connection in both the Straumann BL and BioHorizons Tapered Internal systems. In the NobelParallel CC system, the abutment screw geometry had a greater impact on the microgap size. The microtomography findings revealed a difference in the length of implant-abutment cone generatrixes for the Straumann BL (0.1 mm) and BioHorizons Tapered Internal (0.07 mm) systems, with no difference between the original and non-original abutment for NobelParallel CC implants. The cone generatrix of the screw is smaller with the original NobelParallel CC abutment compared to the non-original one. This is the only negative difference value (–0.34 mm), with the modulus significantly exceeding that of the difference between Straumann BL (0.2 mm) and BioHorizons Tapered Internal (0.2 mm).
Conclusion: The study revealed that selecting an original versus non-original abutment has a greater impact on the microgap size of a taper connection due to differences in abutment geometry, particularly the geometry of its fixing screw.
A Damping Modification Factor Prediction Model for Horizontal Pseudoacceleration Spectrum for Subduction Slab Earthquakes Using Offshore Ground Motions in the Japan Trench Area
Authors: Liu Mingji , Hu Jinjun , Tan Jingyang , Shi Hao
Published: October 2024

This study develops a damping modification factor (DMF) model for offshore ground motion from subduction slab earthquakes that is a function of the damping ratio, spectral period, moment magnitude, focal depth, and rupture distance. The DMF values for 10 damping ratios between 1% and 30% and 34 spectral periods ranging from 0.03 to 5.0 s are calculated using 2803 offshore ground-motion records obtained from the S-net in Japan. An examination of the residuals from a median model, which considers deployment methods, indicates that DMF is influenced by parameters such as magnitude, depth, and distance. The DMF model includes the following components: a median model considering deployment method, a magnitude linear term, a magnitude square term, a focal depth term, an ln(R) scaling, and a constant term. The influence of damping ratio on model coefficients can be simulated by a quadratic function of the damping ratio. In addition, we established a DMF standard deviation model, for which the influence of damping ratio and spectral period on the standard deviation can be simulated by a quadratic function of the damping ratio and a quartic polynomial of the spectral period, respectively. The uncertainty related to the path and site effects is the main source of the deviation of the DMF model. We have conducted a comparison between the offshore DMF model and onshore model proposed by Rezaeian, Al Atik, et al. (2021), revealing that for lower damping ratios, the offshore DMF is generally lower at periods less than 0.2 s and larger at periods greater than 2.0 s compared to its onshore counterparts. The offshore DMF model adjusts the acceleration spectrum proposed by Tan and Hu (2024) to generate smooth pseudoacceleration spectra for most spectral periods.
Precise Relocation and Source Characterization of Two Earthquake Sequences in Yellow Sea Using Regional Lg-Wave Observations
Authors: Park Jun Yong , Kim Won-Young , Kim YoungHee , Shen Xuzhang
Published: October 2024

Two significant earthquakes of magnitude ML 4.6 and 4.5 occurred on 18 January and 3 December 2021 in the central region of the Yellow Sea, respectively. The earthquakes occurred beneath the Gunsan sedimentary basin at about 10 km depth with a strike-slip faulting mechanism on nodal planes striking northwest–southeast (NW–SE) and north-northeast–south-southwest (NNE–SSW). Despite a lack of close-by seismographic stations, we successfully utilized regional Lg-wave observations on both coasts of the sea—the Korean peninsula on the east and eastern China on the west. For nine earthquakes in two event sequences, the Lg-wave differential travel times of the nearby event pairs at the common station are carefully measured using the waveform cross-correlation technique. The double-difference earthquake relocation method is employed to obtain precise relative epicentral locations using the Lg correlation measurements. Relocated epicenters align along the NW–SE direction, indicating that the nodal plane striking the same direction is the likely fault plane on which both sequences occurred. This is the first case reported in the literature in which the causative fault plane has been identified for earthquakes in the central Yellow Sea region. It has an important implication for current regional tectonics; it favors neither old tectonic features trending NE–SW (Qianliyan uplift) nor the north–south alignment of significant earthquakes in the region along the Amur plate boundary. The Lg waves from the earthquake sequences are dominant seismic signals on all three-component records at stations in 160–550 km and allowed us to analyze source properties of the two largest earthquakes using the empirical Green’s function approach. Azimuthal variations of the source corner frequencies suggest that earthquake rupture likely propagated toward southeast (125°) along the fault plane, supporting the aftershock relocation results.
Domestic Demand and Export Performance in CEMAC: An Assessment with Endogeneity-related Model
Authors: Kuikeu Oscar
Published: October 2024

Based on several alternative approaches there is by now some evidence suggesting that there is a negative relationship between exports and domestic sales. But in the majority of cases this regularity has focused on industrialized countries. While the external trade of African countries faces numerous challenges, with the low level of intra regional trade and the concentration of exports in some raw materials. Thus the aim of this paper to assess this new export channel for African countries. We then estimate a dynamic panel model with an error correction mechanism of the export market share (the difference between exports and foreign demand) for the six economies of the CEMAC zone between 1974 and 2021. Through the use of instrumental variables (2SLS) we address the role of endogeneity. According to the results, such link is prominent for African countries such the CEMAC countries where domestic demand impacts effectively negatively exports in CEMAC with a negative elasticity of around 53 %. When allowing for an asymmetric relationship between domestic sales and exports the results remain unchanged suggesting that a significant relationship between domestic demand and exports performance still holds.

Published: October 2024

This research seeks to prove the hypothesis regarding the performance of the Acting Governor of Aceh using the framework of Key Performance Indicators. The measurement variables for the Main Performance Indicators are Adaptability to Change, Financial Management, Infrastructure Development, Public Service, and Stakeholder Satisfaction. Since June 2022, Aceh Province has become a new chapter of leadership after the Helsinki MoU from the Military, this is in contrast to the message of the struggle, that the Military has a place in the hearts of the Acehnese people. So the presence of the military in the Aceh leadership system is interesting to study from its performance during its tenure. This research uses a quantitative descriptive method with data sources from questionnaires via Google Forms with 100 respondents, and data processing is carried out using Smart PLS software. The results of this research show an R Square value of 0.705, thus it can be concluded that 70.5% of the variation in the performance of the Acting Governor of Aceh can be explained by the independent variables in the regression model. R Square identifies quality in the form of strong/medium/weak categories. Several KPI variables that have a significant influence on the performance of the Acting Governor of Aceh are financial management, public service, and stakeholder satisfaction, with P Values ​​of 0.011, 0.020, and 0.035, with these results the performance of the Acting Governor of Aceh was successful in achieving the Main Performance Indicators. Meanwhile, the variables adaptability to change and infrastructure development with P values ​​of 0.405 and 0.343 do not have a significant effect on the performance of the Acting Governor of Aceh on the KPI Indicators.

Published: October 2024

This research aimed at understanding the implementation concerning the Denpasar Municipality government policy which is called “Kube". Kube is a form of community joint business group program that aims to empower village communities in the form of cash assistance. This research used a qualitative approach and explores the opinions of key informants. The results of the analysis showed that various problems in the field caused the “Kube” program to be ineffective due to limited facilities and infrastructure, small development capital and the absence of final marketing of home industry products. Eventually, it became one of the causes of high poverty rates in villages. To overcome this problem, the government is expected to provide greater capital, create a marketing network for home industry products, and train community groups and provide technical assistants in the field

Gastric cyst of the posterior Mediastinum is a rare congenital anomaly of the gastrointestinal tract. They are classified according to their embryological origin, epithelial lining and location, as thymic cyst, cystic hygroma, mesothelial cysts, thoracic duct cyst and cystic malformation of the primitive foregut.

They usually present in neonates or in infancy and are discovered incidentally on radiological examination or gastric endoscopy. Accurate diagnosis of these cysts before resection is difficult and differential diagnosis are varied.

This case report presents a 6-year-old boy who complained of fever for 3 weeks. Chest X-ray revealed right para median oval shaped opacity. HRCT showed a well-defined cystic lesion measuring 9x4.4x3.3 cm in the right side of the posterior mediastinum in the perihilar location. There was also noted vertebral segmentation anomaly in the cervicothoracic spine. Cystectomy was and Gastric cyst was diagnosed through histopathological examination. This case report is presented for its rarity and an unusual delayed clinical presentation.

One of the opportunities how to foster sustainability of public procurement is via purchasing goods and services taking into account balanced and integrated social, economic and environmental aspects while meeting the needs of public institutions. However, more exact methodological procedures are absent in the implementation of green public procurement. Such methodology could enable assessing the quality, quantification and significant connectivity to green and knowledge economy in current practice. Authors of the paper provide more exact methodology of green public procurement of goods and services based on its connectivity to the worldwide standardized indicators of sustainable socio-economic development as well as the results of their own research.

Halotherapy as Adjuvant Therapy for Respiratory Diseases: A Literature Review
Authors: Nugraha Rhea Veda , Rhamdan Daffa Muhammad , Sari Ria Ardia Kartika
Published: October 2024

Halotherapy (HT) is part of salt therapy derived from speleotherapy/speleoclimate, which comes from using a micro size of dry salt in aerosol form (such as sodium, potassium, magnesium, calcium, and sodium chloride) with stable air temperature (18–24ºC) and moderate to high humidity (40–60%) for inhalation inside a cave/imitation cave since the nineteenth century. The benefits of HT as an adjuvant may help patients with many medical conditions, especially respiratory and dermatology diseases. This therapy is believed to alleviate inflammation and the immune response and improve respiratory function, etc. The clinical benefits of HT are advocated, but the mechanisms still need to be explicitly elucidated. This study’s main objective is to critically review and evaluate the evidence from existing literature of HT efficacy as an adjuvant therapy for respiratory disease in a narrative review. This review used a systematic approach and narrative synthesis. PubMed, Google Scholar, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched. Based on preset selection criteria, two reviewers separately looked over abstracts and chose relevant papers. HT improves mucociliary elimination, diminishes airway inflammation, and improves pulmonary function. This adjuvant therapy is safe and does not cause serious adverse events. Therefore, this therapy should be considered an adjuvant therapy for respiratory diseases because of its potential effects. However, scientific evidence of the effectiveness of HT is limited. High-quality further research is required to ascertain the effectiveness of this treatment for respiratory conditions.

Musculoskeletal disorders (MSDs) are abnormalities that affect the musculoskeletalsystem, triggered by various risk factors in the work environment. Commonly, MSDs occur due to non-ergonomic working conditions. It arises from chronic exposure to risk factors that can cause injury to the musculoskeletalsystem, this condition will impact on the social and economic aspects of employees. This research was conducted to determine the characteristics of employees, description of the region and the level of musculoskeletal complaints experienced, risk of work positions based on RULA assessment, and the relationship between risk of work positions and the level of musculoskeletal complaints with an analytic cross-sectional design. The study sample was 33 employees of the Engineering Section of private limited company personnel. The research instrument used was a questionnaire. The results show that the majority of the Engineering Department employees at private limited company personnel were 23 years old (36.4%) and had worked for two to three years (33.3%). As many as 48.5% of employees experienced moderate levels of musculoskeletal complaints. Of the 33 respondents, the majority of employees (63.6%) had a low-risk position, nine people (27.3%) had moderate risk, and three (9.1%) had high risk. There is a significant relationship between the risk of work position and the level of musculoskeletal complaints (P < 0.05). There is a significant relationship between the risk of working position and the level of musculoskeletal complaints in personnel of limited liability companies.

Linezolid as a Treatment for Multidrug-resistant Tuberculosis: A Literature Review
Authors: Nugraha Rhea Veda , Fauziyyah Tazkia , Kaffah Nafisa Silmi
Published: October 2024

Multidrug-resistant tuberculosis (MDR-TB) emerges when Mycobacterium tuberculosis develops resistance to both rifampicin and isoniazid, representing a significant threat that undermines global efforts to combat tuberculosis. The unfavorable prognosis of MDR-TB can be attributed to prolonged treatment duration, the utilization of multiple medications, and the adverse effects associated with drug therapy. This drug moved from Group C (third line) in 2016 and Group 5 (unclear efficacy) in 2011. This is a synthetic oxazolidinone antimicrobial drug and a non-selective mono oxidase inhibitor. Antimicrobials that are both vulnerable to and resistant to gram-positive bacteria can be effectively combatted by linezolid. This study investigates and appraises the utilization of linezolid as a therapeutic intervention in individuals afflicted with MDR-TB, while also scrutinizing the pharmacological attributes of the drug. We also discuss Linezolid’s safety, efficacy, and tolerability for treating MDR-TB. Linezolid medication should be utilized for most patients and is a part of more recent short-course regimens since it has been known to increase the success rate of treatment of DR-TB by increasing the conversion sputum rate. However, primarily hematologic and neurologic, linezolid toxicity is typically treatment-limiting yet should be monitored. Recent studies suggest that dose modification and intermittency can reduce linezolid toxicity. Also, using linezolid in the regimen potentially reduces the treatment duration, but it needs further research.
