Authors: Neelamana Sandhya K. , Janakiram Chandrasekhar , Vijayakumar Priya , Varma Beena , Gopakumar Divya
Published: March 2023

ABSTRACT

Introduction:

Globally, the elderly population is growing at a rate of 2.6% per year. Understanding the health profile and healthcare needs of the elderly is important. The elderly is the most vulnerable and high-risk groups in terms of health status. Their healthcare-seeking behaviour is crucial in any society. There is a need to generate awareness among the public, politicians, and policymakers regarding multiple issues related to the ageing population in the country.

Objective:

To know the health profile and health-related problems of geriatric patients visiting the department of geriatrics at a medical college.

Methodology:

A five-year retrospective analysis of medical records of patients visiting the department of geriatrics from 4 September 2016 to 4 September 2021 was done using Microsoft Excel software and IBM SPSS Statistics. All records in that duration were reviewed and included.

Results:

Descriptive statistics of medical and dental problems of geriatric patients were recorded. The association of medical and dental problems with gender was assessed.

Conclusion:

A majority of geriatricians are unaware of oral health problems. Medical–dental collaboration is inadequate and should be improved in geriatrics.

Published: March 2023

ABSTRACT

Liver diseases are now the leading cause of both morbidity and mortality profile globally with rising trends due to unhealthy lifestyle. Most of the liver diseases are preventable. Scientific evidences have well supported and documented that almost 90 percent of all major liver diseases are either the manifestations of asymptomatic hepatitis virus infections or poor lifestyle choices leading to accumulation of fat in liver that could be detected even before they present themselves as chronic liver diseases. Understanding liver diseases as a preventable disease and practising necessary preventive measures will help in lowering the risks of various types of liver diseases as well as liver cancer.
Atypical presentations of ectopic pregnancies in a rural tertiary care hospital—A case series
Authors: Nongrum Saahil Manna L. , Bhandari Purnima , Jain Shuchi
Published: March 2023

ABSTRACT

In spite of advances in medical sciences, diagnosis of ectopic pregnancy eludes the clinician. In this case series, we describe three variants of life-threatening pregnancies. The successful management of these cases hinged on a strong index of suspicion and early detection. Heterotopic pregnancy is the occurrence of two pregnancies in different implantation sites at the same time, which is uncommon. Heterotopic pregnancy is uncommon in natural conception, despite its prevalence in assisted reproductive technologies. A strong index of suspicion and timely laparotomy was life-saving for the woman. Caesarean scar pregnancy is a form of ectopic pregnancy in which an aberrant pregnancy is implanted at the hysterotomy site of a prior caesarean procedure. Unexplained excessive bleeding at the time of medical termination of pregnancy prompted us to explore and make a timely diagnosis of caesarean scar pregnancy. Finally, tubal choriocarcinoma is a very aggressive, extremely rare trophoblastic tumour that can be either gestational or non-gestational. High serum beta HCG raised the suspicion and timely laparotomy confirmed the diagnosis. An alert clinician who takes timely decisions can avert life-threatening complications in these pregnancies.
Out of breath in pandemic – Is pressure swing adsorption (PSA) technology a solution for saving lives?
Authors: Jain Vishakha , Bhatia Vikas
Published: March 2023

ABSTRACT

In these unprecedented times of COVID-19 pandemic, globally there has been a shortage of medical supplies, hospital beds, health care workers, etc. This was accentuated in India with a shortage of oxygen in the second wave of pandemic. The reasons for shortage were mainly imbalance between demand-supply and these also led to implementation of ingenious solutions in the form of oxygen generators based on PSA technology. The technology was an off shot from OBOGS developed by DRDO and DEBEL for light combat military air crafts. This review discusses the scientific technology behind medical oxygen plants based on PSA, its applications and its advantages to combat the dearth of oxygen.

Authors: Senthilkumar Eyakshara , Gopika Manoharan G. V. Murali
Published: March 2023

Introduction:

The use of morphological features of the mandible is a common approach used by anthropologists and forensic dentists in the determination of sex. Among many anatomical landmarks of the skull, the mental foramen (MF) is a stable landmark on the mandible.

Aim of the Study:

The aim of the study was to analyze the sex-based variations of MF using cone-beam computed tomography (CBCT).

Materials and Methods:

This retrospective study evaluated 60 CBCT scans, retrieved from the radiological archives of our institution. MF was identified in the sagittal section of both the right and left sides. Parameters such as width of MF (W), the height of MF (H), the distance from superior border of MF to the lower border of the mandible (SMF-LM), the distance from inferior border of MF to the lower border of the mandible (IMF-LM), and the interforaminal distance (IFD) were evaluated and compared between the two groups.

Statistical Analysis:

The data obtained were analyzed using the SPSS 27 version software. Paired t-test was done for intragroup analysis; unpaired t-test was done for intergroup analysis.

Results:

The SMF-LM distance, IMF-LM distance, and the IFD were significantly greater in males compared to females.

Conclusion:

Based on the results of this study, the distance from MF to the lower border of the mandible and the IFD showed clear sexual dimorphism and can be used as an effective tool for sex discrimination.

Authors: Koothati Ramesh Kumar , Yendluru Mercy Sravanthi , Dirasantchu Suresh , Muvva Himapavana , Khandare Samadhan , Kallumatta Avinash
Published: March 2023

Background:

Uncinate process (UP) is a key landmark in the lateral wall of the nose which plays a vital role in the ventilation of paranasal sinuses and is also the first structure to be resected during functional endoscopic sinus surgery (FESS). The variations in this structure can lead to intraoperative and postsurgical complications during the FESS procedure.

Aim:

The aim of this study was to evaluate the variations of UP of ethmoid bone using cone-beam computed tomography (CBCT).

Materials and Methods:

Retrospective data of 100 cone-beam computed radiographic CBCT images of paranasal sinuses were evaluated using CS 3D version 3.10.12 software for variations in the superior attachment of UP (SAUP) using Landsberg and Friedman and the presence of pneumatization of UP. Out of 100 CBCT images, 56 were of males and 44 were of females.

Statistical Analysis Used:

Chi-square test was used for statistical analysis.

Results:

In our study, a total of 200 sides in 100 CBCT images were studied and Type I SAUP (51%) was observed as the most common type, followed by Type II (17%), Type IV (11.5%), Type III (10%), Type V (6.5%), and Type VI (4%) is the least common type observed. No statistically significant difference was observed among gender regarding SAUP. Pneumatization of UP was seen in 7% of cases, out of which 4% were in males and 3% were in females.

Conclusion:

Preoperative analysis of UP variations using CBCT can reduce intraoperative and postoperative complications during FESS with less radiation exposure.

Authors: Koothati Ramesh Kumar , Khandare Samadhan , Suresh Dirasantchu , Sravanthi Yendluru Mercy , Avinash Kallumata , Himapavana Muvva
Published: March 2023

Background:

The mandible is considered one of the most reliable bones available for gender discrimination. The mandibular Bonwill's triangle measurements can be used for the identification of gender either on the dry mandible or through three-dimensional imaging like computed tomography (CT) or cone-beam CT (CBCT).

Aim:

The aim of this study was to evaluate the mandibular Bonwill's triangle parameters using CBCT for gender determination.

Materials and Methods:

Morphometric analysis was performed on 80 CBCT images of Indian participants. The mandibular Bonwill's triangle parameters (C-LR, IC-L, IC-R, and semi-perimeter) were measured in the axial sections of CBCT images to predict the gender.

Statistical Analysis:

The Mann–Whitney test was used to compare the mean values between males and females, and the Kruskal–Wallis test was used to compare the mean values among different age groups.

Results:

The participants' ages ranged from 20 to 60 years, with an equal number of males (40) and females (40). The mean distance of C-LR was 106.72 mm in males and 102.59 mm in females. The mean distance of IC-L was 105.09 mm in males and 100.10 mm in females, while that of IC-R was 104.02 mm in males and 99.50 mm in females. The mean value of the semi-perimeter of the Bonwill's triangle was 157.93 mm in males and 151.09 mm in females. All these differences in variables between males and females were statistically significant. Using these variables, the overall prediction accuracy of this study was 75%, with 77.5% in males and 72.5% in females.

Conclusion:

The parameters of the mandibular Bonwill's triangle in the Indian population were observed to be larger in males than females. Hence, these parameters can be used for gender identification in forensic and medicolegal practice.
Model-free cluster analysis for multi-b-value diffusion-weighted imaging of the inferior alveolar nerve
Authors: Otsuka Akiko , Terumitsu Makoto , Matsuzawa Hitoshi , Watanabe Masaki , Seo Kenji
Published: March 2023

Objectives:

Multi-b-value diffusion-weighted imaging (DWI) is useful for the detection of pathological tissues. The signal decay curve of each voxel is generally analyzed using an exponential model; however, the most appropriate curve for an analysis does not necessarily follow a single function. We used model-free analysis to classify data from the inferior alveolar nerve (IAN) into clusters according to the pattern of decay curves. This clustering should be able to classify groups of voxels representing different tissue properties in the neurovascular bundle of the IAN.

Materials and Methods:

DWI with eight b-values was acquired from the IANs of 13 normal volunteers. K-means cluster analysis was used to classify the data. Silhouette analysis was performed to define the optimum number of clusters. The suitability of single and double exponential functions was evaluated for each cluster. The fitting and spatial distributions of parameters associated with diffusion and perfusion using the double exponential model were tested.

Results:

The optimum number of clusters was three. The cluster that exhibited the steepest decay curve showed a higher apparent diffusion coefficient than the others, and was affected by the perfusion component. The cluster with the most gradual decay curve showed the best fit to the double exponential function, and contained the highest volume fraction of the slow diffusion component, indicating a different distribution to the other clusters.

Conclusions:

Clustering of DWI was accomplished without model fitting and was presumably based on the diffusivity properties of IAN, which may be influenced by microcirculation and fascicles.

Published: March 2023

Pediatric critical care is highly sophisticated and precise and is possible only in specialized areas such as pediatric intensive care units (PICUs) or high dependency units equipped with round-the-clock monitoring facilities, skilled and trained staff, and treatment equipment. The need for critical care beds was sharply felt during the COVID-19 pandemic and the Government of India launched the COVID-19 emergency response and health system preparedness package: phase II (ECRP-II) with a hub and spoke model to strengthen pediatric critical care delivery at district level under the skilled supervision of state-level PICUs of the identified center of excellence (CoE). The CoEs will have well-equipped PICUs providing tele-ICU service, mentoring, and technical hand-holding to the district pediatric unit. This model was envisioned to be extended to critically ill children with nonCOVID illnesses after the pandemic abates. For achieving the proposed objectives under the ECRP-II scheme, this guideline aims to provide a practical framework for setting up comprehensive pediatric care units at district hospitals and medical colleges (spoke) well connected with a CoE (hub) for teleconsultation, knowledge exchange, referral, and back referral between hub and spokes.
Insulin Resistance and its Detection Tools
Authors: Mahajan Janhavi , Acharya Sourya , Kumar Sunil
Published: March 2023

Insulin resistance (IR) is a defining feature of obesity, diabetes, and cardiovascular disease, and it contributes to many of the metabolic syndrome's abnormalities. Although our understanding of IR has vastly increased over time, several parts of its assessment continue to elude researchers and doctors. Although the quantitative assessment of insulin sensitivity is not regularly utilized in biochemical investigations for diagnostic purposes, the growing importance of IR has led to further research into its application. IR must be assessed in a number of clinical situations when insulin sensitivity is reduced. IR is being studied more and more in numerous disease states to help researchers better understand its pathophysiology, etiology, and implications. The gold standard approach for determining insulin sensitivity is the hyperinsulinemic euglycemic glucose clamp, although it is impractical due to its labor- and time-intensive nature. As a result, a variety of surrogate indices have been used to make determining IR easier and more accurate. The goal of this study is to highlight different elements and approaches for present and future insulin sensitivity/resistance measurements. Understanding and exploiting the condition will be aided by a thorough understanding of these signs.
The Cross-Cultural Adaptation Process of a Patient-Reported Outcome Measure
Authors: Alagappan Thangamani Ramalingam
Published: March 2023

Patient-reported outcome measures (PROMs) are increasingly being used in the field of physiotherapy. In India, they are primarily used to determine clinical improvement in patients following intervention or for clinical audit purposes. However, clinical, academic, and research professionals' understanding of the construct, development, and psychometric validation of PROMs are uncertain, on the darker side, and unclear. As a result, this state could potentially lead to significant constraints in practice in terms of proper PROM selection, application, and administration. Furthermore, the lack of availability of PROMs in the patients' native language may necessitate a cross-cultural approach.

Published: March 2023

Multicystic dysplastic kidney (MCDK) is a congenital somatic maldevelopment in which the renal cortex is replaced by numerous cysts of varying sizes with insinuating dysplastic parenchyma in between. In 76% of cases, it is unilateral occurring on the left kidney. The condition could be diagnosed by ultrasound during pregnancy or after delivery. According to various studies, it follows a benign course and can be managed conservatively. Here, we present a series of five cases of unilateral MCDK that required surgical management due to either parent's psychosocial constraints or incidental discovery during surgery.

Published: March 2023

The process of medical education delivery has evolved constantly considering the rapid progress in the field of medical sciences, and the varied roles expected of a health-care professional. The current review has been done to explore the role of virtual reality in medical education, and to identify the potential challenges and the suggestions that can aid in the successful introduction of the same in the undergraduate teaching period. An extensive search of all materials related to the topic was carried out in the PubMed search engine, and a total of 23 articles were selected based on their suitability with the current review objectives and analyzed. Keywords used in the search include virtual reality and medical education in the title alone only. Virtual reality is a kind of dynamic and adaptive learning and has been associated with multiple benefits that extend much beyond what is being offered by conventional teaching. Regardless of the multiple benefits, we must realize that it should be used to keep the intended learning outcomes in mind, so as to ensure that it can be integrated into the curriculum effectively. In conclusion, the tool of virtual reality has all the potential to transform medical education delivery in the coming days. Since virtual reality advocates principles of adult learning and gives them a platform to apply their knowledge to practice and subsequently improve on, it is quite necessary that all the medical colleges look to introduce the same within their setup and integrate it with conventional learning.

Published: March 2023

Background:

Restoration of caries having multisurface involvement in primary teeth is a challenge to dentists. The success of the restoration often depends on its longevity. Hence, it is important to systematically review the longevity of stainless steel crowns (SSCs) on primary molars.

Objectives:

To determine the longevity of SSC and to determine the reasons of failure for the same.

Data Sources:

A systematic search was conducted in three databases: PubMed, Embase, and Google Scholar for the studies published from January 1, 2009 to September 25, 2019. Cross references of the selected articles were also searched and hand searching was done for the studies whose full texts were not available through the electronic search. Gray literature was also searched for the studies according to the relevance of this review.

Study Eligibility:

Studies were included if they were published between January 1, 2009 and September 25, 2019, which included comparative assessment of SSCs and other multisurface restorations in primary teeth. The study setting should be clinical based. The study designs included in the review were prospective, retrospective, and randomized control clinical trials. Studies written in the English language and studies written in any other language but are possible to get translated into English were included. Reviews, letters to the editor, and short communications were not included in the review. Studies conducted in permanent dentition were not included. For meta-analysis, randomized control trials and retrospective studies were included.

Authors: Rodrigues Lisa Merlyn , Da Silva Vanita G. Pinto
Published: March 2023

Background:

The portrayal of alcohol as necessary for a vibrant social life has diverted attention from the harms of alcohol use. There is no safe level of alcohol consumption. Studies focusing on problems associated with alcohol use in the elderly are limited.

Aim:

The aim of this study is to determine the pattern of alcohol use in the study population and to study some factors associated with alcohol use in the study population.

Methods:

This was a cross-sectional, hospital-based study conducted in the Rural Health and Training Center at Mandur, Goa, India, over 3 months from February 2022 to April 2022 in persons ≥65 years recruited using systematic random sampling method.

Results:

Out of 207 participants, 114 (55%) were females and 93 (45%) were males. The mean (±standard deviation) age of the study population was 72.73 ± 7.87 years. The total proportion of alcohol use in the study population was 35.3%. Among those who consumed alcohol, 64.4% were current users and 35.6% were former users. Among the current users, 61.7% were low-risk drinkers, 21.3% were at-risk drinkers, and 10.6% indulged in harmful and hazardous drinking, whereas 6.4% had possible dependence on alcohol.

Conclusions:

Increase in aging populations implies that the absolute number of older people with alcohol use is on the increase. Hence, health services need to cater to alcohol screening and treatment methods and services in the elderly population.

Authors: Konikkara Pearl S. , Sahoo Bimal Kumar , Pal Debkumar , Taywade Manish
Published: March 2023

The major purpose of posting MBBS students in community medicine is to understand the ground realities of different existing problems leading to the disease. The students chalk out possible solutions using the available resources and transform the solution to an intervention explicitly designed for the family or individual. Family Health Advisory Services provides a platform to learn the above intent, make family visits in the community, reach a community diagnosis associated with various prevailing and contributing factors, and finally formulate a structured and specific elucidation to root out the disease or health condition. The village visit during the posting in the department of community medicine is crucial for making the preventive and promotive steps before the arrival of ill-health conditions. It also thrills the motive of different schemes and programs by state and central government in their approach and consequence if appropriately and adequately implemented in the anticipated circumstance and situation. The current article explores how a student utilizes community posting to go deep into a family's running and prevailing problems, identify the responsible and probable causes, and find a feasible and possible solution concerning the family's affordability, accessibility, and acceptability.
Automated Detection of fundus retinal image using EGODD algorithm
Authors: K. Subha , Mohideen S. Kother
Published: March 2023

The developed device is tested for optical disc identification in the retinal image of the fundus. The theme chosen was interesting, as optical disc detection plays a critical role in retinal image processing for recognizing other fundus structures and is essential for identifying eye-related diseases. Because human visual vision has been little researched for optical disc detection and an effort to extract data analytics based on eye eyes, the proposed study first discovers how human perception functions for optical disc detection using a bottom-up visual focus paradigm. Eye-view data as the user conducts basic target-search tasks are obtained from separate user groups made up of experts and no expert groups. Extensive data processing has been carried out to extract eye gazing characteristics such as fixation and using computer approach mark regions in the fundus' retinal picture. Segregated labeled data was used to build up a piece of top-down information to bend the search map to the target area. The resulting Eye-based Optical Disk Detection System (EGODD) was tested through normal machine learning algorithms. This proposed framework has been testedand approved for optical disc detection; however, it can also be applied to other applications.
Suicidal Behavior Prediction and Socioeconomic Suicide Indicators
Authors: Nouman Muhammad , Ullah Kareem , Azam Muhammad
Published: March 2023

INTRODUCTION: According to the WHO (World Health Organization), nearly 0.8 million people commit suicide each year, with more than 20 suicide attempts for every self-immolation. Suicidal behaviors have a profound effect on communities, societies, families, friends, and colleagues. After the recognition of public health as a priority by the WHO, various studies are being conducted to prevent it.OBJECTIVES: The investigation's goals were to improve understanding of suicide by identifying socioeconomic indicators correlated with rising suicide rates among divergent legions globally and to develop a prediction model for those who are at a higher risk of suicide by using different predictors of suicide such as tension, depression, anxiety, and so on.METHODS: We used a variety of data mining techniques to create a prediction model for suicide, including Logistic Regression, Multilayer Perceptron, Polynomial/Gaussian/Sigmoid SVM, Decision Tree, and K-Nearest Neighbors. For identifying socioeconomic suicide indicators, we used various descriptive and exploratory analysis techniques such as mean, regression, and correlation.RESULTS: Classification through the Gaussian Kernel - SVM has been shown to have the best results relative to others. Results also stated that many countries saw a decrease in suicide rates between 2006 and 2015, compared to 1996 to 2005. The highest concentrations have been reported in Europe, while the lower has been observed in South America.CONCLUSION: Things are improving, at least according to the statistics. The performance of Gaussian Kernel-SVM has been demonstrated to be superior to the other algorithms for suicide prediction. Data on suicide and suicide attempts are imprecise and difficult to gather. Suicide and suicide attempt monitoring, and surveillance must be improved for suicide prevention initiatives to be effective.

Published: March 2023

Moving and transporting by canoe and boat on rivers and canals is a cultural feature of the Mekong Delta and plays an important role in the economy and society. However, the management and use of equipment to support the monitoring of waterway transport vehicles in this area has yet to receive adequate investment and attention. Given the complicated evolution of the COVID-19 epidemic, it is critical to strengthen oversight of inland waterway management, as well as freight and passenger transportation. This paper presents the design and implementation of an IoT-based support system for managing and monitoring passenger ships and tourism activities in smart cities. This study proposes a hybrid wireless communication network solution that takes advantage of the strengths of LoRa and Zigbee wireless communication technologies, as well as telecommunication networks, to ensure that the system has a wide operating range of several kilometers, low power consumption, and can be deployed in areas where telecommunications are not available. Aside from tracking the journey and managing information about vehicles, drivers, and passengers, the system also aids in the collection of environmental parameters along river routes according to the travel route. An experimental evaluation of the system's operation was carried out for the tourist boat route between two famous tourist sites, Ninh Kieu Key and Cai Rang floating market in Can Tho city, Vietnam.

Published: March 2023

The study provides a unique method for creating an efficient substitution box (S-box) for advanced encryption standards using a Chaotic Logistic Map (CLM) and a Linear Congruential Generator (LCG) (AES) for secure communications in a smart city. The Pseudo-Random Number Generator (PRNG), which is further examined, is constructed using an extensive search of reasonable possibilities for the initial seed and set parameters. Using statistical testing, the performance analysis of the new S-box is assessed. Additionally, the resilience of differential, as well as linear cryptanalysis, is shown. It is derived using other features, including nonlinearity, the Bit Independence Criterion (BIC), and the Strict Avalanche Criterion (SAC). The suggested S-box has good potential and is usable for symmetric key cryptography, according to the features of the new S-cryptographic box.
Podmiotowość polityczna pierwszej Solidarności
Authors: Bäcker Roman
Published: March 2023

Podmiotowość polityczna pierwszej Solidarności znacząco ewoluowała w okresie między strajkami lata 1980 roku ogłoszonym 13 grudnia 1981 roku stanem wojennym. Na poziomie artykulacyjnym nastąpiło przejście od fazy suplik poprzez zagregowane postulaty do dojrzałego narodowego programu politycznego. Strajki okupacyjne stały się podstawą trwałego potencjału samoorganizacyjnego narodu polskiego. Nie osiągnięto jednak poziomu wielowymiarowości organizacyjnej. Potencjał mobilizacyjny rósł od lipca 1980 roku aż do strajku generalnego, po czym zaczął systematycznie spadać. Podpisanie porozumień oznaczało pisemną akceptację istnienia odrębnego podmiotu społecznego przez dotychczasowego monopolistę (partię rządzącą). Było to świadectwem uzyskania statusowego awansu społecznego. To formalne uznanie nie było bezwarunkowe i zostało ostatecznie zanegowane poprzez wprowadzenie stanu wojennego. Znaczna część środowisk robotniczych, studenckich rolniczych osiągnęła trwałą podmiotowość polityczną na poziomie podstawowym. Political subjectivity of first “Solidarity” The political subjectivity of the first “Solidarity” evolved significantly in the period between the strikes in the summer of 1980 and the martial law announced on December 13, 1981. At the articulation level, there was transition from the supplication stage through aggregated postulates to the mature political program of nation. Occupation strikes became the basis for the Polish nation’s lasting potential of the self-organization. However, the level of organizational multidimensionality was not achieved. The mobilization potential grew from July 1980 until the general warning strike, and then began to systematically decline. The signing of the agreements meant written acceptance of the existence of separate social entity by the former monopolist (ruling party). It was to obtain collective status benefits. This formal recognition was not unconditional and was finally denied by the imposition of martial law. Significant part of the working, student and agricultural circles achieved the level of political subjectivity at the basic level.
Koncepcje reformy gospodarczej rozważane podczas I Krajowego Zjazdu Delegatów NSZZ „Solidarność”
Authors: Wołk Grzegorz
Published: March 2023

Pogłębiający się od połowy lat siedemdziesiątych kryzys gospodarczy był jednym z głównych czynników wybuchu solidarnościowej rewolucji. Powstanie Solidarności nie sprawiło, że problem zniknął. Solidarnościowi delegaci zdawali sobie z tego doskonale sprawę. Chociaż najwięcej emocji podczas zjazdu NSZZ „Solidarność” budziły kwestie polityczne, to wątki gospodarcze pojawiały się podczas obrad nieustannie.

Większość wypowiedzi delegatów odnoszących się do reform gospodarczych ograniczała się do ogólników na temat konieczności reform i nie precyzowała, jak miałyby one wyglądać. Większość postulatów delegatów miała lewicowy i socjalny charakter. Niezwykle rzadko pojawiały się pomysły liberalne, takie jak koncepcja Stefana Kurowskiego. Analiza dyskursu gospodarczego jednoznacznie pokazuje, że NSZZ „Solidarność” – jak na związek zawodowy przystało – forsował pomysły reform jak najmniej szkodliwe dla najuboższych grup zawodowych, widział potrzebę wprowadzenia działań pomocowych, a kosztami reform niejednokrotnie chciał obciążyć przedstawicieli nomenklatury.

The concepts of economic reform considered at the First National Congress of Delegates of the Solidarity Trade Union

The economic crisis, which had been started since the mid-1970s, was one of the main factors in the outbreak of the Solidarity revolution. The birth of Solidarity did not make the problem disappear. The Solidarity delegates were well aware of this. Although political issues aroused most emotion during the debates, economic themes were constantly present.

Most of the delegates for the congress speeches referring to economic reforms were limited to general statements about the necessity of reforms, without specifying how they were to look like. Most of the demands of the delegates were of a leftist and socialist nature. Liberal ideas, such as Stefan Kurowski’s concept, were extremely rare. The analysis of the economic discourse shows very clearly that, as befits a trade union, the Solidarity pushed through the reform ideas which were the least harmful for the poorest part of society, saw the need to introduce aid measures, and often wanted to burden the representatives of the communist nomenclature with the costs of the reforms.
Władze Komitetu Krakowskiego PZPR wobec redakcji „Gazety Krakowskiej” od września 1980 do grudnia 1981 roku
Authors: Juchowski Piotr
Published: March 2023

W czasie tzw. „rewolucji Solidarności” (wrzesień 1980 – grudzień 1981) niektóre z czasopism Polskiej Zjednoczonej Partii Robotniczej stawały się bardziej autonomiczne względem sprawujących nad nimi kontrolę instancji partyjnych. Jeden z przykładów to redakcja „Gazety Krakowskiej”, która w tym okresie prezentowała często poglądy niezależne od instrukcji partii i jej lokalnego komitetu. W artykule autor dokonał analizy stosunku władz Komitetu Krakowskiego PZPR wobec przekazu „Gazety Krakowskiej”. Zwrócono uwagę na specyfikę tych relacji oraz wpływ, jaki w ówczesnym okresie władze KK wywierały na redakcję „GK”, a także ich rezonans wśród dziennikarzy. Tekst odnosi się także do ewolucji tych relacji i przyczyn ich zmiany w drugiej połowie 1981 roku. Autor zwrócił szczególną uwagę na stosunek władz KK PZPR do swoistej autonomii redakcyjnej „Gazety Krakowskiej”.

The authorities of the Krakow Committee of the Polish United Workers’ Party towards the editorial office of “Gazeta Krakowska” from September 1980 to December 1981

During the “Revolution of Solidarity” (September 1980 – December 1981), some of the magazines of the Polish United Workers’ Party (PUWP) became an independent way of local structures PUWP, which had controlled them. One of the example is the editorial office “Gazeta Krakowska” (GK), which during this period, presented often autonomous views towards to PUWP. In this article, the author analyzes the attitude of the authorities of the Krakow Committee PUWP (KC) towards to the content of GK. The attention was paid to the specificity of the reports and the impact of authorities KC on the editorial office of GK, as well as their resonance among journalists. The text also refers to the evolution of these relations and the reasons for their change in the second half of 1981. The author pays particular attention to the view authorities KC towards to specific autonomy of GK. In the article, the author presented in which spheres were allowed for freedom and in which party discipline was demanded. The text also refers to the “common interests” that could have been linked by the liberal-minded authorities of the KC and the editorial staff of GK for example in striving for internal party reforms or fighting the conservative part of PUWP.

Wykład wykładu: Rzecz o mowie noblowskiej Olgi Tokarczuk. On Olga Tokarczuk’s Nobel Speech: The Lecture about a Lecture
Authors: Kajtoch Wojciech
Published: March 2023

Esej monograficzny Wojciecha Kajtocha, znanego medioznawcy, historyka i teoretyka literatury, ma wiele walorów poznawczych. Porusza zasadniczo nowy temat, który wcześniej nie został zbadany, przy zastosowaniu oryginalnej metody badawczej łączącej w sobie elementy jakościowej i ilościowej analizy tekstu wystąpienia polskiej noblistki, a w istocie rzeczy – analizy dyskursu, jako że Kajtoch bierze pod uwagę także czynniki paralingwistyczne. W swoim badaniu nawiązuje do teorii tekstowego obrazu świata, której zresztą jest twórcą i która wydaje mi się niezwykle skuteczna w rozwiązaniu problemu, jakim są złożone i wieloaspektowe relacje między działalnością językową a kulturą. Z recenzji prof. dr. hab. Aleksandra Kiklewicza The monographic essay by Wojciech Kajtoch – renowned expert in media studies, literary historian and scholar – has a high cognitive value. It tackles an essentially novel, still unstudied subject with the use of an original research method which incorporates elements of qualitative and quantitative analysis and applies them to the text of the speech delivered by the Polish Nobel laureate. The method is in fact akin to discourse analysis, since Kajtoch is also interested in paralinguistic factors. In the discussion, the author refers to the theory of textual image of the world, which he himself has coined and which seems particularly useful for studying the issue of complex, multi-faceted relations between linguistic activity and culture.

A vez do público?
Authors: Leo Luiz
Published: March 2023

A partir de uma revisão das contribuições epistemológicas do campo da comunicação política e propondo uma maior ênfase metodológica à percepção do “público” nas iniciativas de comunicação política, este trabalho destaca, de forma comparada, variáveis tecnológicas que cercam as rotinas de cidadãos em países latino-americanos, sobretudo aqueles que experimentaram recentes transições democráticas, de centro ou direita para regimes de esquerda. Com foco no México, Argentina, Chile, Colômbia e Brasil, são examinados, em perspectiva panorâmica, os recursos digitais mais característicos de cada país, bem como algumas das mobilizações que ganharam relevo naquelas respectivas realidades nacionais, em meio as discussões sobre política no ambiente digital. Desta forma, associa-se aos esforços de ampliação do leque dos estudos de comunicação política regionais, através da identificação e de uma sistematização, de caráter comparado, de iniciativas de comunicação política gestadas pela sociedade civil latino-americana.
O dito e o não dito no Twitter

A disputa pela prefeitura do Rio de Janeiro em 2020 ocorreu em eleições marcadas por circunstâncias atípicas, como a pandemia de Covid-19 e a ascensão da extrema direita no pleito anterior. O cenário político carioca também estava marcado por sucessivas prisões de ex-governadores. Nos últimos anos, a política se adaptou às plataformas de redes sociais, em especial o Twitter, que, atualmente, configuram o ambiente principal da comunicação, abrangendo as informações buscadas pela sociedade e os recursos de interação e integração social (GOMES, 2021). Com isso, os atores políticos ganharam novas obrigações, estratégias e riscos em suas interações com a sociedade. Dessa forma, monitoramos os perfis oficiais de Eduardo Paes e Marcelo Crivella no Twitter durante a eleição para a prefeitura do Rio de Janeiro em 2020. A pesquisa revela as estratégias adotadas pelos candidatos. Os resultados mostram que o perfil de Paes foi muito mais ativo e dialógico no Twitter.

On the Road: Emergent Spatiality in #Vanlife
Authors: May Lawrence
Published: March 2023

‘Vanlife’ is a term utilised on social media sites, including YouTube, to denote images and videos that represent a lifestyle centred around long-distance travel using converted vans. The Vanlife phenomenon demonstrates the potential for networked culture and storytelling to combine to create emergent spaces, fostered not only by individual digital media objects but also the connected digital networks they occupy. In this article I ask how digital media practices are used by Vanlife travellers in order to construct such emergent spaces, and what the characteristics of these spaces might be. This investigation has a particular focus on the capacity for the creative practices used to tell visual stories online to combine representations of ‘real world’ experiences and environments, with the individual and communal desires, rhetoric and, at times, fictions, of the burgeoning Vanlife alternative lifestyle. Taking a netnographic approach (Kozinets, 2002), and guided by Henri Lefebvre’s trialectic model of space (1974), I conduct analysis of a set of Vanlife YouTube videos and explore the construction of different layers of spatiality as well as the productive tensions that arise between these. As Vanlifers undertake and document their freewheeling travels, their production of spaces serves to establish the unending road trip as a viable alternative lifestyle. Vanlife videos also work to formulate new cultural and aesthetic dimensions for the areas their creators explore, destabilising and redefining the meanings of the spaces, experiences and communities its travellers encounter. Equally, the idealised spaces of Vanlife are themselves disrupted by jarring intrusions from the external world and its everyday problems, a tension that further illustrates the continually negotiable nature of spatial meanings and highlights the role digital media might play in accentuating and accelerating this fluidity.
experiencia del SIMA en los procedimientos relacionados con la legitimación y representatividad en la negociación colectiva (2012-2021)
Authors: Borrego Gutiérrez Martín
Published: March 2023

En un modelo de negociación colectiva de eficacia general como el español quien negocia de entre los posibles interesados en la negociación, en que ámbito y el porcentaje de representatividad que ostentan organizaciones empresariales y sindicales son aspectos de vital importancia para los negociadores.

El trabajo aborda las dificultades de los negociadores de convenios colectivos y de otras instituciones en la constitución de las mesas de negociación y durante la gobernanza del convenio colectivo, a través del análisis de los 283 procedimientos relacionados con la legitimación y representatividad que se tramitaron en el SIMA en la última década. El trabajo analiza también las causas de la discrepancia, tanto legales como extralegales, y el contenido de los acuerdos de mediación y laudos arbitrales dictados.
