Multimorbidity and its Associated Factors in Korean Shift Workers: Population-Based Cross-Sectional Study (Preprint)
Authors: Hong Hye Chong , Kim Young Man
Published: November 2023

BACKGROUND

Multimorbidity is a crucial factor that influences premature death rates, poor health, depression, quality of life, and use of health care. Approximately one-fifth of the global workforce is involved in shift work, which is associated with increased risk for several chronic diseases and multimorbidity. About 12% to 14% of wage workers in Korea are shift workers. However, the prevalence of multimorbidity and its associated factors in Korean shift workers are rarely reported.

OBJECTIVE

This study aimed to assess multimorbidity prevalence, examine the factors associated with multimorbidity, and identify multimorbidity patterns among shift workers in Korea.

METHODS

This study is a population-based cross-sectional study using Korea National Health and Nutrition Examination Survey data from 2016 to 2020. The study included 1704 (weighted n=2,697,228) Korean shift workers aged 19 years and older. Multimorbidity was defined as participants having 2 or more chronic diseases. Demographic and job-related variables, including regular work status, average working hours per week, and shift work type, as well as health behaviors, including BMI, smoking status, alcohol use, physical activity, and sleep duration, were included in the analysis. A survey-corrected logistic regression analysis was performed to identify factors influencing multimorbidity among the workers, and multimorbidity patterns were identified with a network analysis.

RESULTS

The overall prevalence of multimorbidity was 13.7% (302/1704). Logistic regression indicated that age, income, regular work, and obesity were significant factors influencing multimorbidity. Network analysis results revealed that chronic diseases clustered into three groups: (1) cardiometabolic multimorbidity (hypertension, dyslipidemia, diabetes, coronary heart disease, and stroke), (2) musculoskeletal multimorbidity (arthritis and osteoporosis), and (3) unclassified diseases (depression, chronic liver disease, thyroid disease, asthma, cancer, and chronic kidney disease).

CONCLUSIONS

The findings revealed that several socioeconomic and behavioral factors were associated with multimorbidity among shift workers, indicating the need for policy development related to work schedule modification. Further organization-level screening and intervention programs are needed to prevent and manage multimorbidity among shift workers. We also recommend longitudinal studies to confirm the effects of job-related factors and health behaviors on multimorbidity among shift workers in the future.

Introduction. This study examines the effect of job descriptions and capability specifications on the information seeking behaviour patterns of policy analysts at the Ministry of Administrative and Bureaucratic Reform.

Data Collection Methods. Data was gathered via questionnaires. The respondents were 118 policy analysts across beginner, intermediate, and advanced levels.

Data Analysis. Research data were analysed using PLS-SEM.

Results and Discussion. The study reveals that the job descriptions had a positive impact on the policy analysts’ information-seeking habits at the Ministry of Administrative and Bureaucratic Reform. However, the capability specifications did not show any substantial positive effect.

Conclusion. The research concludes that job descriptions play a crucial role in shaping the information-seeking behaviour of policy analysts, whereas the impact of capability specifications remains insignificant. The study further suggests several stakeholders responsible for managing information, like libraries, should take an active role in handling the data produced by policy analysts from various units. This would help the sustainable use of such data in the creation of public policies.

Manuver jaringan merupakan serangkaian kegiatan manipulasi jaringan tegangan menengah yang melibatkan dua penyulang atau lebih dengan tujuan meminimalisasi terjadinya padam akibat gangguan dengan memperhatikan susut daya pada jaringan. Dalam melakukan manuver jaringan, pemilihan susut daya terendah bertujuan meminimalisasi kerugian dan mendapatkan penyaluran maksimal. Susut daya terjadi akibat adanya resistansi pada kawat penghantar jaringan tegangan menengah yang teraliri arus sehingga menimbulkan suhu tinggi. Manuver jaringan pada penyulang PWO2 Purworejo dapat dilakukan pada penyulang PWO5 atau penyulang PWO11 karena memiliki konfigurasi loop. Penyulang PWO2 memerlukan pelimpahan beban sebesar 144,3 A dengan opsi manuver jaringan pada penyulang PWO5 memiliki arus beban total 148,97 A dan penyulang PWO 11 memiliki arus beban total 204 A. Berdasarkan perhitungan susut daya resistansi dari kedua opsi manuver jaringan memiliki perbedaan dimana, PWO5 sebesar 2,7% dan PWO11 sebesar 6,7% dari total daya penyulang. Menimbang dari total beban dan susut daya aktif jaringan, PWO5 menjadi opsi utama dalam manuver jaringan pelimpahan beban dari penyulang PWO2. Persentase susut daya pasca manuver jaringan mengalami kenaikan menjadi 6,3% dari total daya penyulang penerima beban (PWO5). Dalam manuver jaringan, tingkat Energy Not Supplied (ENS) pada saat pemadaman turun dari 13.493,67 kWh menjadi 77,64 kWh. Kerugian yang dialami dari ENS dan kenaikan susut daya pasca manuver jaringan, saat terjadinya pemadaman tanpa manuver jaringan kerugian total sebesar 20,1 juta rupiah. Namun, dengan manuver jaringan saat terjadi pemandaman,  kerugian total 2,8 juta rupiah atau turun hingga 85,9%.

Aloe vera (Aloe vera) has a unique texture because it is in the form of a gel which has anti-inflammatory, wound healing, antibacterial and anticancer properties. Aloe vera can be developed as a disclosing agent. Clinical trials and toxicity tests can be the basis for the clinical use of aloe vera gel. The purpose of this study was to determine the ability of aloe vera gel as a disclosing agent based on clinical trials and toxicity tests. The research method is by carrying out sample preparation, extraction, gel preparation, clinical trials on human test subjects, and toxicity tests with the BSLT method. Data were analyzed descriptively, linear regression. The test results showed that the average plaque score in formula I (thick gel) was 3.62, while the average plaque score in formula II (less viscous gel) was 2.58. This shows that the more viscous aloe vera gel formula is better than the less viscous aloe vera gel. Based on the test, it is known that the average LC50 value is 2596.88 µg/ml. According to the literature, if the LC50 value is above 1000 µg/ml then the sample does not have a toxic effect.

Cancer continues to be one of the most difficult global healthcare problems. Although there is a large library of drugs that can be used in cancer treatment, the problem is selectively killing all the cancer cells while reducing collateral toxicity to healthy cells. There are several biological barriers to effective drug delivery in cancer such as renal, hepatic, or immune clearance. Nanoparticles loaded with drugs can be designed to overcome these biological barriers to improve efficacy while reducing morbidity. The pathological processes of cancer are complex. Current methods used for chemotherapy have various limitations, such as cytotoxicity, multi-drug resistance, stem-like cells growth, and lack of specificity. Nanomedicine plays an important role in these evolving tumor treatment modalities. We discuss how nanomedicine can be combined with these treatment modalities, provide typical examples, and summarize the advantages brought by the application of nanomedicine. This highlights the progress, challenges and opportunities in cancer nanomedicine and discusses novel engineering approaches that capitalize on our growing understanding of tumour biology and nano–bio interactions to develop more effective nanotherapeutics for cancer patients. This review discusses the current use of clinically approved nanomedicines, the investigation of nanomedicines in clinical trials, and the challenges that may hinder development of the nanomedicinesfor cancer treatment.

Until 2019, 10.9 million DM cases were found in Indonesia and are suspected of continuing to increase. Cinnamon (Cinnamomum Burmannii) has several active ingredients vizcoumarin, cinnamat, cinnamaldehid, polyphenols and flavonoid can increase glucose transport by GLUT 4 in adipose cells and skeletal muscles so as to significantly reduce blood glucose. Thus, cinnamon has the potential to be a useful product for the community, namely a diabetes herbal medicine. The purpose of this research was to determine the ratio of the temperature of the cinnamon steeping water with the duration of steeping on the glycemic response of diabetic rats.

This research uses Completely randomized design (CRD) with 2 factors, namely the first factor (P): steeping water temperature (65 oC, 75 oC, and 85 oC) and brewing time (20 minutes, 25 minutes and 30 minutes) and the second factor (L): test time (30 minutes, 60 minutes, 90 minutes and 120 minutes).  This study also carried out control (-) and control (+) as a preliminary study to determine the glycemic response in test animals. Each treatment will be repeated 3 times to obtain 33 experimental units. The parameters analyzed were blood sugar levels, the percentage (%) increase in blood sugar levels, and the percentage (%) decrease in blood sugar levels.

The results showed that temperature of the cinnamon steeping water (Cinnamomum Burmannii) and the duration of brewing can reduce the blood sugar levels of mice every time the test is carried out. The best treatment was obtained from the ratio of the temperature of the steeping water and the duration of steeping, namely 65 oC and brewing time for 25 minutes, determined based on the percentage decrease in blood sugar level, which is equal to 53,02%.

Published: November 2023

Creep behavior of wood plays a fundamental role in precision processing of wood. In this work, experimental creep tests have been conducted to determine the influence of earlywood vessel location and moisture content on creep behavior of Quercus alba (white oak). Time-moisture superposition principle was applied to predict long-term creep behavior of white oak. Results revealed that both of instantaneous and 45-min strain of specimens increased with the increasing of moisture content and decreased with increasing distance between earlywood vessel belt and load-bearing surface significantly. Additionally, the time-moisture superposition principle was found to have feasibility to predict creep behavior of white oak with various earlywood vessel locations and moisture content ranges (6 % - 18 %). We believe that the proposed investigation was beneficial for the processing precision and civil engineering applications of wood.

Published: November 2023

Since 1993, in the Russian Federation, only according to formal criteria, there have been at least 5 attempts to reform the civil public service. With each new round of reforms, the number of laws and regulations regulating the civil service increased and the transformations multiplied. But the quality of reforms and the socio-economic and political consequences they caused remained low. The author’s many years of research experience on the issues of the state civil service, as well as the practice of consulting activities and work on the jury of the All-Russian competition “Best HR Practices and Initiatives in the System of State and Municipal Administration” suggested that one of the reasons for the failures lies in ignoring the special property of state organizations - their personal dependence. The purpose of this article is to develop the concept of personnel-dependent organizations as applied to the state civil service system. A detailed analysis of the characteristics of personnel-dependent organizations is carried out, their impact on approaches to personnel management in the civil service, and recommendations are offered for restructuring the management of the civil service system, taking into account its personnel-dependent nature.
RESTRUCTURING INVESTMENT CAPITAL IN MANAGING THE RISK OF FINANCIAL LEVERAGE OF BUSINESS STRUCTURES
Authors:   Central Russian Institute of Management, Branch of RANEPA, MATVEEV V.V.
Published: November 2023

Carrying out investment activities in the context of modern macroeconomic and geopolitical uncertainty is associated with many different financial and economic risks. They can not only reduce the effectiveness of investment processes, but also lead to the financial insolvency of the entity as a whole. A striking example of such a critical threat is the risk of financial leverage. It is based on the irrational use of equity and borrowed capital. Approaches to leveling out this problem involve, on the one hand, the provision of specialized regulatory influence at the state level on the parameters of attracted capital. On the other hand, practical local decisions of management personnel are formed on restructuring the sources of financing investment projects. At the same time, the first group of methods is actively and specifically applied by the Government of the Russian Federation according to the end of 2023, but the second group is actually “at the mercy” of the professionalism of risk managers. The purpose: the formation of scientific and practical recommendations for the restructuring capital of business structures in order to maximize the effectiveness of investment projects in the conditions of stabilization (preservation) of financial stability. Methodology: based on an assessment of the risks of using capital for a specific research object of the research object, practical recommendations for leveling the risks of financial leverage are formulated. As a result, when implementing an investment project, in order to stabilize the financial stability of the company, the use of five promising areas of capital restructuring is justified. Among them, a certain variability between scenarios can be noted. Firstly, to increase equity and simultaneously reduce borrowed capital. Secondly, to exclusively reduce the company's liabilities and reduce the value of its property. And thirdly, to expand the property complex by attracting new co-investors (attracting new equity capital without the possibility of management). In this case, the direct selection of the optimal and most effective approach should be made not only on the basis of the selected particular features, but only after calculating all costs, as well as after analyzing all updated profitability parameters.

The article provides methodological grounds for identifying the middle class in general and the representatives of the youth middle class in particular. It is especially noted that representatives of the middle class serve as the state support in the socio-political sphere, as they have a high level of legal consciousness, civil and political culture, are the main driving force of reforms and innovations in the socio-economic sphere, bearers and disseminators of highly cultural and moral values in the spiritual -cultural sphere of modern Russian society and actively relay all of the above to other segments of the population. Accordingly, expanding the boundaries of the middle class is one of the primary tasks for Russian society, and young people are the immediate potential for its development. All of the above determined the purpose of the work - on the basis of the developed methodology, to identify the characteristics of youth as the potential for the formation of the middle class in modern Russian society, to draw up a portrait of young representatives of the middle class. The article presents a comprehensive methodology for identifying the middle class in general and its young representatives in particular, as well as its theoretical model, including the core, semi-core, near and far periphery. This model involves the use of such criteria as socio-professional, self-identification, leisure and recreational and the criterion of personal responsibility. The aprobation of the presented methodology was carried out in the sociological laboratory of the Department of Sociology and Social Technologies as part of the study “Youth as the potential for the development of the middle class.” An analysis of the youth middle class according to all the stated criteria allowed us to assert that it is this social group that has the immediate potential for the development and expansion of the Russian middle class.

Study of the Geotechnical Methods of the Structure Tilts Elimination
Authors: Petrakov A. A. , Petrakova M. A. , Panasyuk M. D.
Published: November 2023

Introduction. Nowadays, in the frame of development of the new territories, when building the industrial and business facilities, there arises the need to develop the territories having the so-called complicated engineering-geological and mining-geological conditions. Ensuring the normal operation of the buildings and structures built on the territories of the land slide hazard, subsiding soils and on the underworked territories is the problem which is relevant to solve.

Materials and Methods. The parameters of the new geotechnical method of the structure tilts elimination by digging a deep trench along the outer contour of a foundation slab’s part are investigated. The soil massif is modeled by the solid finite elements. Correlations for determining the Poisson coefficients of the soil as a function of its strength properties are proposed. The problem is solved taking into account the building and mounting works sequence. For this purpose, the "Mounting works" module of the "Lira" software has been used.

Results. The implementation of the geotechnical method of eliminating the tilts allows ensuring the overall stability of the soil massifs during the works. It provides the opportunity to hold the maximum pressures acting on the massif fixed within the values slightly differing from the mean pressures of the normal operation of the structure. Moreover, deepening the compensation trench causes practically no changes of the vertical pressures values, which leads to the pressures displacements deeper into the soil massif. The possible reasons for the subfoundation extra settlements, in case of implementing this method of tilts elimination, are investigated. It has been found that these processes are related to the lateral pressures reductions in the soil massif due to the subfoundation pliability increase, as well as to the edge pressures rises beneath a foundation slab.

Discussion and Conclusion. The proposed method of tilts elimination (geotechnical method), which includes the design of a compensation trench along the building foundation contour, minimises the impact on the massif’s overall stability and reduces the impact on the nearby buildings and structures during eliminating the tilts of the existing foundations. Practical recommendations for correcting the tilts by the geotechnical method are given.
Quality Control of Hidden Construction Work Using Photographs Attached to Inspection Reports
Authors: Mamonova O. A. , Zholobova E. A.
Published: November 2023

Introduction. In construction production the problem of increasing the reliability of information contained in the certificates of inspection of concealed works is more and more often solved with the help of their photofixation. Based on the results of earlier studies, the authors prove that using the diagnostic informativeness of photographs it is possible not only to confirm the fact of execution of concealed works in the required volume, but also to obtain additional information about their quality. For effective extraction of this information it is necessary to develop a method of quality control of hidden construction works on the basis of photographs attached to the inspection certificates, taking into account modern scientific achievements in the field of photogrammetry and color-texture analysis of photographic images.

Materials and Methods. The developed method of quality control of hidden construction work is based on the use of contour, pixel, macro- and micro-texture analysis of photographic images. When developing the method, the results of numerous visual inspections of building structures (including the opening of their internal elements) and comparison of these results with the information contained in the certificates of certification of concealed works were used.

Results. The article presents the results of a study carried out at the Don State Technical University on the development of a method for quality control of hidden construction work using photographs attached to inspection reports. The algorithms developed by the authors for analyzing photographs of building structures to control their quality are presented. The article contains proposals for the systematization and storage of typical textures of surfaces of building structures.

Discussion and Conclusion. The priority condition for successful application of the new method of quality control of concealed construction works is its methodological support, which establishes a unified procedure for their photo fixation, additional requirements for the composition and parameters of photographs, rules of registration, storage and use of them as annexes to certificates of inspection of concealed construction works, as well as the regulations for comprehensive analysis of photographs with the use of appropriate software.
The Effect of Borax Addition as Buffering Agent on Storage Stability of Melamine-Formaldehyde Resin in the Production of High-Pressure Laminates
Authors: Muslem Abdul Halim , Rahmi Rahmi , Fujiani Midia
Published: November 2023

High-pressure laminates (HPL) is one of the applications of thermosetting resins for wood-based materials as protective and decorative panels covering building furniture. Melamine-formaldehyde (MF) resin is one of the resins that play a role in the production of high-pressure laminates. This resin has low storage stability due to cross-linking between free melamine methylols accompanied by a decrease in pH during the storage process. This study aims to improve the storage stability of melamine-formaldehyde resin by adding borax as a buffering agent. Synthesis of MF resin was conducted by polymerization and condensation steps followed by the addition of borax at concentrations of 0, 0.5, 1, 1.5, and 2% when the endpoint was reached. The characterization of the resin includes the analysis of the physical and chemical parameters of the resin and the analysis of the functional groups of the resin by FT-IR. Storage stability study of MF resin was carried out by daily visual observation and determination of daily changes in pH and viscosity. MF resin was further used in the production of high-pressure laminates. High-pressure laminates characterization includes quality analysis based on SNIISO4586-7:2017 and analysis gloss level. In this study, 1.5% MF borax resin had the highest storage stability, namely 11 days. HPL quality analysis complies with SNIISO4586-7:2017 standards. High-pressure laminates of 1.5% borax MF resin has the highest gloss level, which is 115.

Pyrolysis that occurs with the equipment configuration used a heating rate of 7-14°C/minute, where the main reaction of pyrolysis occurs at a temperature of 150°C to 270°C so that the set temperature does not have a large effect on the yield or characteristics of bio-oil. EP pyrolysis produced an average bio-oil yield of 41.64%, while EFB pyrolysis produced an average bio-oil yield of 46.72%. Bio-oil produced by pyrolysis of EP has a characteristic average value for density of 1.062362 gr/mL, viscosity of 2.1749 cP, and pH 2-3. Meanwhile, bio-oil produced by pyrolysis of EFB has a characteristic average value for density of 1.043146 gr/mL, viscosity of 1.3582 cP, and pH 3-4. EP bio-oil has a composition of C7-C10 carbon, while EFB bio-oil has a composition of C6-C19 carbon.

Palm oil mill effluent (POME) is high strength wastewater obtained from palm fruit processing, which contains high chemical oxygen demand (COD), biological oxygen demand (BOD), and other contaminants. The pollutant load in POME can serve as a source of nutrients for microalgae growth. As a result, the goal of this work was to utilize Spirulina sp. and Nannochloropsis oculata to reduce the nutritional content of POME while producing biomass rich in high-value chemicals. The cultivation was conducted in a batch reactor using various POME fractions (0-20%) under 5,000 lux light intensity and continuous aeration at a temperature of 22-28°C and a salinity of 30 ppt for 14 consecutive-days. The results demonstrate that Spirulina sp. produced the most biomass at 15% POME, accounting for 4.67±0.95 g/L with 0.57±0.11 1/day of growth rate and 3.33% of COD reduction efficiency. Meanwhile, Nannochloropsis oculata thrived in 20% POME, producing 4.43±0.36 g/L biomass, 1.18±0.31 1/day growth rate, and 14.43% COD reduction efficiency. In the proximate analysis. Spirulina sp. and Nannochlorpsis oculata provided 0.87%; 1.11% lipid and 1.03%; 0.86% protein, respectively.

The small businesses in Kafue District take place to provide solutions that answer the overall economic and social development difficulties such as increase in the levels of unemployment, poverty, and inequality. The government’s function has always been to create a favourable environment for business for all SMEs to thrive better. Due to such difficulties encountered by the citizenry, despite existing empowerment policies, the government introduced the Constituency Development Fund to support SMEs within their cooperatives in Zambia; this is to reduce the barriers that obstruct SMEs’ profile opportunities to grow and to be sustainable to fulfil government and society expectations. The drive of this study was to analyze thematically different profile opportunities of SMEs in the manner in which they can access CDF. The study focused on opportunities that lie in each SME’s profile and identified the profiles according to their needs. The method which was used in this study was qualitative and employed purposive sampling to comprehend SMEs’ profile opportunities. The results of this study resolved that SMEs’ profile needs to be helped to core exists as they utilize or struggle to access funding from the existing CDF. The emergent themes reported in this study show that there are significant qualitative profiles to consider as officers in charge of CDF disburse the funds to the beneficiaries. In conclusion, the study recommended policymakers support small businesses to grow in an inclusive, innovative and sustainable way in line with the financial opportunities available. The findings in this study will establish equal distribution, utilization, and management of resources by responsible government agencies in Kafue, Zambia.

Blockchain technology for small and medium business under the conditions of instability of the twenties of the 21st century
Authors: Kudryavtsev M. V.
Published: November 2023

This study is aimed at studying the possibility and necessity of using blockchain technology for payments by small and medium–sized businesses for various realistic scenarios in the context of instability associated with the consequences of the 2020–2021 pandemic, geopolitical changes and sanctions pressure on companies in the Russian Federation. Blockchain as a technology has been gaining interest in the last few years. A lot of research has been conducted to understand how technologies for payment can be used for large projects, and to determine if this technology is suitable for various realistic scenarios. When it comes to implementing blockchain technology for payments, companies and businesses find themselves at a crossroads due to the lack of a clear vision. This leads to serious doubts about whether such blockchain technology is suitable for payments by companies that intend to use it. There are real examples of the implementation of blockchain technology in large international companies as they have both financial and technical support for the development and implementation of the technology. However, when it comes to small and medium–sized businesses, it must be said that they often suffer from a lack of resources, especially when it comes to the introduction of new technologies. The purpose of this study is to consider the features to apply blockchain technology by small and medium enterprises for payments in unstable environments, define the opportunities to introduce and use this technology by small and medium enterprises, and also potential problems that may arise while using the blockchain technology to process the payments.

Published: November 2023

Perang makassar merupakan salah satu perang yang besar yang terjadi di Nusantara sehingga penting untuk di telaah. Melihat dampak yang disailkan cukup besar untuk terjadinya perubahan tatanan kehidupan masyaraka Makassar pada waktu itu sehingga membuat kerajaan Gowa-Tallo harus menerima kekalahan dan menganti semua kerugianperang, serta harus tunduk terhadap pemerintahan Hindia Belanda. Kajian ini merupakan kajian sejarah dengan tahapan heuristik, kritik, interpretasi, dan historiografi. Berdasarkan hasil kajian awal diperoleh informasi terkait latar belakang terjadinya perang Makassar, jalanya perang Makassar sampai pada akhirnya runtuknya kerajaan Gowa-Tallo sebagai tanda berahirnya perang Makassar. Walaupun demikian perlawan tetap dilanjutkan oleh raja-raja dari kerajaan bawahan Makassar sehingga membuat sebahagian masyarakat harus memilih antara ikut memberontak atau tunduk pada pemerintahan Hindia belanda. Pada akhirnya pada akhir abad ke-17 para pembangkan berhasil ditaklukkan dan pemerintah berhasil mendirikan Pusat Pemerintahan yang berpusat di Benteng Fort Roterdam. Hal inilah yang kemudian akan dikaji peneliti agara mampu memeberikah hasil terkai kehidupan sosial ekonomi pasca perang Makassar.
