Published: June 2023

Breast cancer is the most commonly diagnosed disease in women as well as the leading cause of cancer death. Neoadjuvant chemotherapy (NAC) is a standard treatment technique for locally advanced breast tumors, with the goal of clinical downstaging. Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) is used to diagnose breast cancer and could be used to access the NAC treatment response. However, the assessment of treatment response at the early phase is crucial and challenging. Previous studies show that radiomic features have the potential in quantifying the pathological changes due to NAC. In this work, an attempt has been made to objectively quantify the early phase changes observed on the DCE-MRI due to NAC using radiomic features. Different radiomic features are extracted from DCE-MR images of Visit 1 (pre-treatment) & 2 (post-treatment) to quantify the treatment response and are statistically analyzed. Further, kinetic features from the images are also extracted and associated with the radiomic features and are tested using Spearman’s correlation test. Results demonstrate that radiomic features such as energy, homogeneity, entropy, kurtosis have shown a highly significant difference between the two visits (p ≤ 0.05). Similarly, the association between significant radiomic features and kinetic parameters shown a positive correlation with r = (0.48 - 0.66), p = (0.00029 - 0.016) respectively. Hence it appears that the association of radiomic and kinetic parameters would be used as an adjunct measure in differentiating the NAC treatment visits at early stages.

The loading experienced by military helicopter and fighter aircrew can lead to spinal injury by degrading the soft tissues. Fighter pilots endure low frequency high magnitude loading, while helicopter pilots endure high frequency vibrational loading over longer periods of time. The purpose of this study is to analyze intervertebral disc material properties, including elastic modulus, failure strain, and failure stress. This will provide data to model the annulus fibrosus to predict the risk of injuries. Quantifying the risk to specific spinal locations could provide insight to improve the design of protective clothing and equipment. Single layers of the porcine annulus fibrosus were subjected to tensile failure tests to determine the mechanical properties. Results showed a significantly (p< 0.05) higher elastic modulus in the circumferential direction compared to the axial direction. There was also a significantly greater elastic modulus for samples from the lateral region of the disc compared to the posterior region. There was no significant difference for the anterior region or specimen depth with regards to elastic modulus. Failure stress showed significant differences between superficial and deep specimens as circumferential and axial testing directions. Failure strain only had differences between circumferential and axial directions. This data can be used to help predict where in the disc an injury may occur. Because of the decreased posterior elastic modulus, tensile failure is more likely to occur in that region.

Published: June 2023

Prediction techniques are extensively used in medical applications and health care devices. The prediction of the infusion flow rate for the required drug dosage and drug concentration in a smart wireless infusion pump is necessary for precise drug flow for the patients. In this paper, the prediction model has been developed to predict the lag time using Gaussian Process Regression (GPR) technique with a squared exponential kernel. Currently, a smart wireless infusion pump is incorporated with its smart drug library. The required parameters such as drug dosage, drug flow rate are utilized as inputs to predict the lag time and to minimize start-up delays using the proposed regression technique. The evaluation of the prediction model is done by the coefficient of determination (R2), mean absolute error (MAE), and root-mean-squared error (RMSE). These prediction results are verified for predicting lag time for two different carrier flowrates 10 ml/hr and 50 ml/hr. The outcome of the study indicates that the regression model GPR has better prediction accuracy with a mean R2 of 0.9. Hence, the GPR technique is capable to achieve quick infusion and optimal flow rate with minimized lag time for smart infusion pumps.

In this work, an attempt has been made to classify dichotomous emotional states using Electrodermal activity (EDA) and geometric features. For this, the annotated happy and sad EDA is obtained from the online public database. The EDA is subjected to discrete Fourier transform, and Fourier coefficients in the complex plane are obtained. The envelope of the complex plane is identified using the α-shape method. Five geometric features, namely center of gravity, eccentricity, convexity, rectangularity, and convex hull area are computed from the envelope and statistical analysis is performed. Two machine-learning algorithms, namely random forest (RF) and support vector machine, are considered for the classification. The results show that the proposed approach is able to classify the dichotomous emotional states. The rectangularity feature is found to be distinct and shows a statistically significant difference between the happy and sad emotional states (p<0.05). The RF classifier yields the highest F-m and AUC of 87.8% and 93.8%, respectively in differentiating emotional states. Thus, it appears that the proposed method could be used to understand the neurological, psychiatric, and biobehavioral mechanisms associated with happy and sad emotional states.

Alzheimerâ€™s Disease (AD) is a progressive irreversible neurodegenerative disorder which involves the deformations in brain sub-anatomic regions. Recent studies suggest that these deformations could be characterized using bi-planar information extracted from structural Magnetic Resonance (MR) image features. However, analysis and fusion of these bi-planar features have been a challenging task in AD differentiation. In this study, an attempt has been made to fuse the characteristics of axial and sagittal view MR images using Canonical Correlation Analysis (CCA) for the differentiation of Healthy Controls (HC) and AD. For this, MR brain images obtained from a public database are skull stripped and spatially registered. Morphometric features are extracted from the pre-processed mid-sagittal and mid-axial images using histogram of oriented gradients. Further, these extracted features are fused using CCA. The performance of classifier is analyzed for the variations in canonical component dimensions. Results indicate that the morphometric feature spaces extracted from sagittal and axial planes individually overlap for HC and AD. The proposed CCA based fusion of sagittal and axial features exhibit variations between HC and AD images for a canonical feature dimension of 30. Performance of the adopted approach confirms that the bi-planar feature fusion is essential for the differentiation of AD.
MODELAGEM DE DADOS EM DATA WAREHOUSES MODERNOS: COMPARAÇÃO ENTRE MODELOS NO CONTEXTO NAS NOVAS PLATAFORMAS ANALÍTICAS

Published: June 2023

After the second half of the 1980s, companies only stored data from their transactional systems. However, naturally, the need arose to obtain metrics based on data that could support decision makers in their management activities. As a result, several types of Decision Support Systems were developed, such as Data Warehouses. This is a technology in which data is extracted from transactional systems, subsequently transformed and loaded into a database. In this way, end users were able to perform analyses from multiple perspectives through a single, integrated source of data. This was a successful model for a long time, until the 2000s saw an exponential growth in the amount and variety of data generated by organizations. This spurred the development of technologies for distributed storage and processing such as Hadoop, and then cloud computing platforms such as Azure, AWS, and Google Cloud. This new context of analytical environments has brought about important changes, such as a significant decrease in data storage costs and the decoupling of processing and storage. In view of this, it is natural to ask questions such as: do traditional data models like Star Schema still make sense nowadays or is the best option to embrace bolder proposals like One Big Table? When investigating what data professionals are thinking about the subject, one realizes that there is no consensus around the topic. This is because each specific case presents its own peculiarities, so that no model will meet the needs of all situations. However, despite these limitations, it is possible to achieve a balanced result between storage, maintenance, and performance by knowing the advantages and disadvantages presented by each of them.

Authors: Dantas Ribeiro Hellen , Guilherme Galvão José , Robson de Araújo Lazaro , de Oliveira Nóbrega Rafaela
Published: June 2023

INTRODUÇÃO: A obesidade é caracterizada pelo acúmulo excedente e atípico de gordura corpórea, sendo capaz de predispor, no paciente, outras comorbidades. Desta forma, pacientes obesos acabam optando por uma terapia farmacológica para a perda de peso, método considerado por eles rápido e fácil, descartando as dietas e exercícios físicos como meios naturais essenciais a esse procedimento. O tratamento é baseado no uso de anorexígenos, sendo, muitas vezes, utilizados de forma incoerente, indo contra as especificações dos órgãos sanitários. OBJETIVO: Evidenciar o emprego errôneo dos anorexígenos anfetamínicos no processo de emagrecimento. METODOLOGIA: O presente trabalho refere-se a uma revisão integrativa de literatura, considerando a inserção de artigos publicados na última década (2012-2022), nos idiomas inglês e português, oriundos das posteriores bases de dados eletrônicos: Biblioteca Virtual em Saúde (BVS), Scientific Electronic Library Online (SciELO) e National Library of Medicine National Institutes of Health (PubMed). Durante esse processo, foram empregados para a busca descritores em Ciências de Saúde (DeCS) e em associação com o operador booleano AND. RESULTADOS E DISCUSSÕES: As drogas anfetaminas são de grande abrangência em nosso país. Diante das pesquisas na literatura, foi possível observar que a obesidade implicou o aumento do consumo destas substâncias, especialmente em atribuição dos seus efeitos anorexígenos e das promessas de uma aparência física padronizada. A falha na informação e a facilidade de aquisição são outros quesitos fundamentais que cooperam com a utilização indiscriminada desses fármacos. CONCLUSÃO: A obesidade teve um aumento considerável na sociedade contemporânea, e a busca pelo emagrecimento rápido, com finalidades estéticas, tornou o consumo inadequado dos anorexígenos constante, principalmente os de origem anfetamínicos, e com um perfil de segurança cada vez mais reduzido, mediante o uso alienado por parte dos usuários, favorecido pelo fácil acesso a esses receituários prescritos.

Authors: Buzinov Roman V. , Syurin Sergei A. , Kizeev Aleksei N.
Published: June 2023

Introduction: Despite all preventive measures constantly taken, high incidence of occupational diseases is still registered in workers of copper-nickel enterprises.
Objective: To obtain new knowledge about the conditions, timing, structure and frequency of occupational diseases in order to develop methods for their more effective prevention in workers involved in pyrometallurgical copper-nickel ore processing.
Materials and methods: We have analyzed incidence rates of occupational diseases in a cohort of 664 workers who processed copper-nickel ore in 2007–2020.
Results: Working conditions during pyrometallurgical processing of copper-nickel ore correspond to hazard classes 3.2–3.4 with the chemical exposure being of paramount importance in the development of health disorders (45.6 % of cases). In 2007, 664 workers were examined and 158 occupational diseases were diagnosed in 65 (9.8 %) of them in the years 2008–2020, respiratory and musculoskeletal diseases being the most prevalent categories (50.6 % and 29.1 %, respectively) and chronic bronchitis and sensorineural hearing loss – the most prevalent diseases (27.8 % and 17.1 %, respectively). We established non-occupational disorders (arthralgia, osteochondrosis, early signs of hearing impairment, etc.) contributing to further development of occupational diseases. Smoking history (> 5 packs/year) was found to promote occupational diseases of the respiratory system (RR = 4.84; 95 % CI: 2.51–9.35). Crane operators (17.5 % of the workers) were found to be at highest risk of occupational diseases (366.1 cases per 10,000 workers).
Conclusions: Based on data on previously registered occupational diseases, working conditions, length of service, occupation, and clinical conditions, criteria for five risk categories have been developed to predict occupational diseases by time, nosology, and severity of the course in metallurgists involved in copper-nickel ore processing.

Authors: Nikitchenko Serhii
Published: June 2023

Introduction. The economic expediency of the diversification of production activities is determined by its impact on the economic and financial state of the enterprise, since the result of any diversification should be the reduction of risk and the emergence of synergistic effects, especially in the field of finance, thanks to the possibility of free intra-company transfer of funds to the areas of activity that develop the most dynamically. The effect of diversification largely depends on the choice of directions (vertical integration, diversification based on existing types of activities, creation of conglomerates). Methods. Modern general scientific and special methods of economic research were used during the research, in particular: systematic approach, comparative, dialectical, abstract and logical methods. The results. It has been proven that the diversification of production activity will be expedient in the following cases: narrowing the possibilities of development of the current business; strengthening the competitive advantages of the enterprise and its products due to diversification; the opportunity to use the existing potential for organizing activities in other fields; the ability to reduce production costs; availability of financial and organizational resources to implement diversification. Discussion. In the post-war period, there will be a change in the priorities of production and economic activity of business entities, which is caused by a change in the direction of the country's economic development. This circumstance will lead to the improvement of the theoretical foundations of the diversification of business entities. Keywords: activity, business entity, diversification, economic feasibility, directions of diversification.

Mi punge vaghezza di festeggiare Paola così…
Authors: D’Achille Paolo
Published: June 2023

L’articolo ricostruisce la storia dell’espressione mi punge vaghezza, documentata a partire dai primi anni del secolo XVII e che mantiene ancora una certa vitalità. Alle analisi morfologica e sintattica, che mostrano come vaghezza (formato dall’aggettivo vago nel senso di ‘desideroso’ e dal suffisso -ezza) sia soggetto e mi oggetto diretto, si affianca quella semantica: al significato di ‘desidero, ho voglia (di qualcosa)’ (legato all’uso metaforico di pungere ‘stimolare’), si è di recente sovrapposto quello di ‘ho il presentimento’ (probabilmente legato a un diverso valore di vago ‘incerto’).

Special Issue Introduction – The 2022 Italian general election: a political shock or the new normal?
Authors: Giovannini Arianna , Valbruzzi Marco , Vampa Davide
Published: June 2023

This introduction to the special issue places the 2022 Italian general election within the recent electoral history of Italy and the broader European context. Following the same multidimensional structure adopted for this collection of articles, here we address general questions regarding the significance of the last election, its dynamics, and implications. Firstly, to what extent did it represent a change compared to previous Italian elections? Secondly, can Italy still be regarded as an anomaly in the European context? Have the 2022 results widened or narrowed the political gap between the country and its neighbours? By providing a longitudinal and cross-sectional overview, our aim is to suggest some interpretative keys, which, in conjunction with the rich data presented and discussed by the authors of each article, may enable readers to draw general lessons about recent developments in Italian and European politics. Our overall argument is that, while clearly significant in its political implications – producing the most ideologically right-wing government in republican history led by the first female prime minister –, the 2022 general election did not represent a radical change from previous Italian elections. Instead, it marked a further step in the emergence of a ‘new political normal’ characterised by volatility, fragmentation, mainstreaming of populist ideas and actors, polarisation and the reframing of socio-economic and socio-cultural cleavages. Additionally, while Italy can be regarded as the most advanced manifestation of these transformations, we observe similar shifts in most Western European countries, indicating that their seemingly unshakable stability is now in question.

Isomyristicin results from myristicin isomerization and is reported to have the same biological activity as myristicin, an antidepressant. Myristicin at a specific dose causes toxicity, so it is necessary to study isomyristicin, which is estimated to have the same biological activity as myristicin. However, there has been no test related to isomyristicin having antidepressant activity. Therefore, this study aimed to determine the antidepressant activity and the optimum dose of isomyristicin to decrease the immobility time of male white mice (Mus musculus). This study used 30 male white mice divided into six groups: positive control, negative control, normal control, and isomyristicin dose 1.5 mg/Kg BW, 3 mg/Kg BW, and 6 mg/Kg BW mice. The method to measure the immobility time of male white mice is the Forced Swimming Test (FST) and Tail Suspension Test (TST) to induce depression. To analyze the normality data using a Shapiro Wilk and a one-way ANOVA to analyze the significant difference in the data. The result showed all doses of isomyristicin have the ability to antidepressant, and the optimal dose was 1,5 mg/kg BW mice with 82 % as the decrease percentage and proved by post hoc with sig. p (<0,05).

The practice of education in schools still needs to improve in the form of limited studies focusing on parental involvement in the learning process of children with special needs in Indonesia. This study aimed to identify the forms of parental involvement in planning, implementing, and evaluating learning programs from 2017 to 2022 using the Systematic Literature Review (SLR) method. The stages of implementation using the Cooper version are (1) formulating the problem, (2) collecting data, (3) evaluating the feasibility of the data, (4) analysis and interpreting the relevant data, and (5) organizing and presenting the results. Data was collected by searching for keywords related to the concept to be reviewed on the data source page (Google Scholar, Perpusnas.go.id, and Portal Garuda). The results of this study indicate that parental involvement in learning planning is as a giver and recipient of information about the child's condition in the assessment process but has yet to be involved in determining the learning program. Meanwhile, mostly parents accompanied children when studying at home during the pandemic, despite many challenges in the learning implementation.  As for the evaluation process, parents monitored their children’s progress and gave feedback to the teachers about their children’s achievements. The findings of this study indicate the need for further studies to improve school-parent collaboration in Indonesia.

The Effects of COVID19 Disgust Experiences on Job Satisfaction: A Mediating Role of the Emotional Dissonance and the Moderating Role of Perceived Labor Protection System
Authors:   The Korean Association Of Personnel Administration, Cho Hyunmin , Jung Heungjun
Published: June 2023

With the COVID-19 pandemic increasing dislike for others, emotional management of essential workers who perform jobs where face-to-face work is unavoidable is becoming an important task for organizational and personnel management. This is because the disgust experienced by customers due to COVID-19 can cause negative emotions and affect job attitudes. This study has focused on the organizational management of COVID-19 disgust in a situation where the COVID-19 pandemic is prolonged and the possibility of repeated occurrence is predicted. This study analyzed the impact of COVID-19 disgust experienced from customers on job satisfaction through emotional dissonance for essential home visit workers (N=419) who had no choice but to perform face-to-face work even during the COVID-19 period. In addition, we empirically analyzed how the indirect effect of the COVID-19 abhorrence experience, which hinders job satisfaction through emotional dissonance, has a moderating effect regulated by the emotional labor protection system. As a result of the analysis, it was found that the experience of disgust to COVID-19 caused emotional dissonance and had a negative impact on job satisfaction, and it was confirmed that this relationship could be alleviated more than when the level of the emotional labor protection system was high. Overall, the results of this study have implications on the importance of managerial considerations for the essential workers facing customer’s bad behaviors.
A Case Study on a Typology of the Job-Based Pay System of Public Organizations: A Resistance to the Organizational Change Perspective
Authors:   The Korean Association Of Personnel Administration, Yoo Youngsam , Kim Taehyung
Published: June 2023

The wage system in public institutions has been cited as a target for government reform due to issues of excessive labor costs, debt growth, and low service quality. Those issues are partly due to seniority-based pay, which increases wages based on years of service. Although the government has emphasized the need for job-based pay for public organizations, very few public institutions have actually introduced this system. In order to promote the adoption of these policies, it is necessary to analyze how institutions introduced job-based pay system overcome resistance to change. This study aims to categorize job-based pay introduced by public institutions through case studies of seven public institutions that introduced job-based pay, and to clarify the reasons that these institutions can introduced job-based pay from the perspective of a resistance to organizational change. Our findings indicated that two out of seven public institutions are differentiating basic salaries according to job value, four are differentiating allowances, and one is differentiating incentives. First, from the perspective of organizational culture and characteristics, we found that organizational culture consistent with the purpose of the job-based pay system had a positive effect on overcoming resistance to the introduction of job-based pay. Next, it was found that minimizing negative expectations for the results after the introduction of the job-based pay helped overcome the resistance to the introduction of the job-based pay. Finally, we identified that the acceptance of job-level introduction was strengthened by utilizing external experts, holding employee briefings, and establishing a job-level introduction committee to overcome organizational change resistance. Based on these results, we discussed theoretical and practical implications of the study and future research directions.
Luxury Service and Distinction Work: A Qualitative Study on Luxury Hotel Employees
Authors:   The Korean Association Of Personnel Administration, Yang Kyunguk
Published: June 2023

Since Hochschild’s groundbreaking book, scholars have explored various aspects of service work. Yet, luxury services, which serve affluent customers who have more social and economic power than the service workers, have received less attention. These workers strive to make their customers feel special, performing works that affirm their elite status. This study proposes the term “distinction work” to describe these practices. By identifying a unique type of work in the luxury service sector, this study enriches the service work literature, which has traditionally examined different kinds of work (e.g. body work, care work, aesthetic work, etc.) in each service sector. This paper conducts a qualitative study to analyze the distinction work of hoteliers in luxury hotels. The researcher worked as a temporary worker for 5 weeks at a restaurant in a 5-star luxury hotel in downtown Seoul and also interviewed 32 hoteliers from 6 luxury hotels. The data was analyzed following the grounded theoretical method. The hotelier recognizes who each customer is, anticipates their needs, and fulfills them even before they ask. Moreover, the hotelier takes on the physical burden of the customer, which reinforces the customer’s privileged position and entitles them to make any demand to the employees. The discussion section highlights the theoretical importance of distinction work in the service work literature.
