Authors: Reddy V Venkateswara , Hadalgi Pradeep M
Published: July 2022

Using the CADFEKO tool, a T-shaped Microstrip patch antenna (MSPA) with an epoxy substrate was designed and simulated to achieve the best possible result. MSPA is frequently utilized because of its numerous benefits, including its light weight, low volume, and low manufacturing cost. The antenna's bandwidth, gain, return loss, VSWR, and radiation pattern were assessed. Maximum impedance is attained at 6.85 GHz, antenna gain is 8dB, directivity is 4.5, and return loss is -10.80dB at 5.725 GHz and 12.48dB at 10.6 GHz for the T-shape rectangular Microstrip patch antenna for ultra-wideband applications. 50Ω is used to power the T-shaped Microstrip antenna. The simulated results of the proposed antenna are good radiation patterns. The return loss is less than -10 dB and VSWR is less than 2 throughout the UWB band. At 3.1 to 10.6 GHz resonant frequencies, the S11are -10.80dB,-12.48dB, and antenna efficiency is 100 % due to all losses being zero.

5th Generation Cellular technology is not just one more technical innovation, rather it is going to be the the most prominant platform for the other innovations to get it happened. Mobile networks are changing the way people communicate and access information. Network access at anytime and anywhere is transforming the telecom industry. 5G technology will enable flexible, reliable, and secure wireless networks to connect people with all applications, services, and things, thus leading human race into the era of "Everything on Mobile". The 5th Generation of the Internet in Telecommunications will open the new doors to the Internet of Things (IoT), Industrial Internet of Things (IIoT), Artificial Intelligence (AI), Machine Learning (ML), Neural Networks, etc. But for the last several years since its designing and implementation strategies, 5G technology has been embroiled in various social and technical controversies. The testing of 5G in different countries of the world has shown that in future the user will get the expected data speed but the time to come will show how much the power level of high frequency signal harms human health and other services. Initially 3rd Generation Partnership Project (3GPP) and ITU have combinely proposed two way of infrastructure for the implementation of 5G i.e. SA architecture and NSA architecture with pros and cons with both. This analytical paper narrates the different issues that may arise upon the implementation of 5G infrastructure. The severity of issues related to multiple frequency bands availability, health hazards, airline frequency band conflict as well as coding discrepancy will be different for Stand Alone infrastruction option and for Non Stand-Alone infrastructure choice.

Performance Tuning Of Apache Spark Framework In Big Data Processing with Respect To Block Size And Replication Factor
Authors: Joshi Brijesh Y , . Poornashankar , Sawai Deepali
Published: July 2022

Apache Spark has recently become the most popular big data analytics framework. Default configurations are provided by Spark. HDFS stands for Hadoop Distributed File System. It means the large files will be physically stored on multiple nodes in a distributed fashion. The block size determines how large files are distributed, while the replication factor determines how reliable the files are. If there is just one copy of each block for a given file and the node fails, the data in the files become unreadable. The block size and replication factor are configurable per file. The results and analysis of the experimental study to determine the efficiency of adjusting the settings of tuning Apache Spark for minimizing application execution time as compared to standard values are described in this paper. Based on a vast number of studies, we employed a trial-anderror strategy to fine-tune these values. We chose two workloads to test the Apache framework for comparative analysis: Wordcount and Terasort. We used the elapsed time to evaluate the same.

Comparative Analysis of Image Enhancement Algorithms
Authors: Bane Sumedh , Choudhary Ritik , Gupta Shashwat , Tewari Kavita
Published: July 2022

In the complex instruments utilised in essential fields such as satellite cameras, CT scanners, and High-Resolution Cameras (Underwater), image capture is critical without human-rated aberrations, sounds, or atmospheric disturbances. Even full reference QA (quality assessment) approaches have a limited ability to predict quality accurately. As a result, the difficulty of evaluating and enhancing photographs is further subdivided into domain-specific issues by focusing on a small set of artefacts. The most popular is entropy, which is usually relevant in picture coding: it is a lower limit for the average coding length in bits per pixel that may be attained without any loss of information by an optimal coding scheme. The word 'specific' is significant because it establishes right away that the strategies covered in this paper are primarily problemsolving techniques. For example, a procedure that works well for improving X-ray images may not be the ideal option. Thus, a method that works well for boosting X-ray photos may not be the greatest option for enhancing photographs obtained by a satellite thousands of miles away from the Earth. Image enhancement algorithms proposed in this paper are Intensity-Hue-Saturation transformation, Histogram Equalization algorithms, Edge Detection techniques and Retinex theory algorithms. These algorithms are implemented under satellite imagery, medical scans, underwater images, and their parameter analysis.
The Definition of Asbestos - A Manufactured Defense to Avoid Regulation and Victim Compensation
Authors: Tran Triet , Egilman David , Bird Tess , Clancy Kate
Published: July 2022

Background: The Occupational Safety and Health Administration (OSHA) first identified asbestos as a regulated workplace hazard in 1971. In the half century since, OSHA has fully rescinded only one of its hundreds of regulations, one that happened to regulate a form of asbestos found as an accessory mineral in cosmetic talc. This extremely rare action grew out of a 20-year campaign by Talc Mining and Manufacturing Companies (TM&MCs) to redefine some of the asbestos routinely found in talc as “non-asbestos” to keep talc out of the regulation. Under this new definition, at least 50% of the products sold as asbestos became “non-asbestos.” Methods: We used systematic search techniques and grounded theory to review published studies, government records, corporate documents and public statements. Results: Current asbestos regulations and test methods rely heavily on asbestos geologic definition which determine the majority of asbestos fibers as “non-asbestos.” In essence, this geologic definition defined some asbestos out of existence. However, asbestos regulations should be driven by the health effects of asbestos. Conclusions: TM&MCs funded experts and lobbied OSHA to promote an overly restrictive definition of asbestos and to support inadequate test methods in place of more effective procedures. These companies subsequently relied on these same restrictive definitions and inadequate tests to falsely claim that their cosmetic talcs are free of asbestos. Replacing the restrictive geologic definition of asbestos with a health definition is needed to protect the public from the well-known dangers of asbestos.

Published: July 2022

Purpose: Viral infections had been historically observed in chronic disease development and complications including although not limited to hepatitis C, influenza A, cytomegalovirus (CMV), Epstein bar virus (EBV), HIV and herpes simplex. Epidemiologic data had implicated CMV, herpes simplex and hepatitis C in type II diabetes (T2D). With the observed increased incidence T2D in COVID-19 among children and adults, this review aimed to examine scientific literature on immune and endocrine systems dysregulation in T2D and pancreatic neoplasm. Materials & Method: A qualitative systematic review (QSR) was utilized in assessing the immune system deregulation and endocrine system involvement in chronic disease development such as T2D. The PubMed was the main search engine in studies identification with several search terms such as “SARS-CoV-2 and T2D”, “COVID-19 and T2D”, SARS-CoV-2 and insulin resistant”, etc. Results: Viral pathogens such as CMV, influenza A, and herpes simplex and hepatitis C infections have been implicated in decreased insulin sensitivity (IS) and increased insulin resistant (IR). Similarly, these pathogenic microbes increased the T2D incidence and complications. SARS-CoV-2 a COVID-19 causative pathogen had been observed in increased risk and incidence of T2D among children and adults. While data are not currently available on the precise mechanistic process, SARS-CoV-2 viral infection in T2D incidence may be explained by excess pro-inflammatory cytokines elaboration (cytokine storm) resulting in increased IR and decreased IS, leading to glucose intolerance and T2D. Further COVID-19 may increase pancreatic neoplasm in populations with increased incidence of COVID-19, due to pancreatic beta cells and insulin receptors dysregulation and cellular dysfunctionality as abnormal cellular proliferation. Conclusions/Recommendation: SARS-CoV-2 a causative pathogen in COVID-19 morbidity is associated with increased incidence of T2D, which is explained in part by immune and endocrine system integration dysregulation, resulting in cytokine storm, decreased IS and increased IR, implying glucose intolerance and T2D. Additionally this pathogenic microbe may result in increasing incidence of pancreatic neoplasm, a malignant neoplasm with the worst prognosis and excess mortality due to late stage at diagnosis and marginalized biomarkers of susceptibility and morbidity.
Nothing Short of Devastation: Disabled Writers’ Responses to the COVID-19 Lockdown During the First Year of the Pandemic
Authors: Herat Manel
Published: July 2022

The purpose of this paper is to investigate the impact that the coronavirus pandemic has had on people with disabilities and underlying health conditions by analysing their personal stories. The research questions explored in this paper are (1) what impact did lockdown have on disabled people’s mental health? and (2) were there any positive impacts of lockdown? To answer these research questions, 46 personal stories from the first year of the pandemic from March 2020 to March 2021, when restrictions were imposed on people’s lives, were selected from the internet to examine how lockdown and self-isolation impacted people’s lives. The data was analysed using two corpus software: first, LIWC (Pennebaker, Conglomerates, 2022), to see what the language reveals about people’s emotional struggles during the pandemic through analysing stylistic features such as the use of words for cognitive processes, emotional affect and personal pronouns; secondly, SketchEngine was used to search for keywords and to analyse concordance lines. The results from the data analysis reveals that paradoxically, while the first year of the pandemic has had a massive impact on mental health breakdown, it has also at the same time, given people the opportunity to find themselves and to explore avenues they would not have done, if not for the lockdown. The results also show that the duration of the lockdown had a severe impact on mental health, particularly anxiety and depression. In terms of language use, there was a high frequency of use of cognitive processes, first person singular pronouns and negative emotions. The high use of cognitive processes revealed that through their stories, the writers were reappraising and reflecting on the events they have experienced; the use of first person singular pronouns illustrated the self-focus of the writers and the negative emotions showcased their immersion in the events and the state of their mental health condition. The low number of positive emotions reveal the upheaval caused by the pandemic.

Published: July 2022

Ovarian teratomas are the ovary's most frequent germ cell tumors and can be either mature or immature. Ovarian teratomas can also have a monodermal form; struma ovarii is the most common type and are usually multilocular cystic lesions with variable locules. Another less common types of monodermal lesion are ovarian carcinoids. Mature cystic teratomas are composed of predominantly fat, while immature teratomas have a larger solid component with only small foci of fat. This review article discusses the various types of ovarian teratomas with their respective imaging findings, gross pathological, histopathological, complications, and clinical management.

Published: July 2022

Purpose: To identify the MRI features that aid in the characterization of ovarian granulosa cell tumors. Materials and methods: 11 MR pelvis of an adult woman with pathology-proven ovarian granulosa cell tumors with surgical pathology. We evaluated the patient's age, Ca-125, size, laterality, and with MRI features such as indirect signs (i.e., thickened endometrium > 0.9 cm), morphology (cystic, solid-cystic, or solid), subacute hemorrhage, T2 signal (low or intermediate-to-high), restricted diffusion (B values: 0, 50, 1000 sec/mm3/ADC), and dynamic enhancement (intense or similar to myometrium). Also, the presence of ascites, peritoneal implants, or adenopathy. Results: The final cohort included 11 women with a surgical-pathological diagnosis of granulosa cell tumors. The median age was 52.4 years (range, 17-80). The Ca-125 level was with a median within normal limits. The median size was 9.4 cm. Most cases were unilateral (81.8%) and more frequent on the left (54.5%). MRI Analysis: 36.4% had endometrial thickening. Ovarian granulosa cell tumors were polymorphous: cystic (54.6%), mixed solid-cystic (9.1%), and solid (36.3%). Most GC had intermediate to high signal on T2 (90.9%), restricted diffusion (81.8%), intense enhancement (81.8%), and 36.4% had intraparenchymal bleeding. 9.1% had associated implants/adenopathy/ ascites at diagnosis. Conclusion: The MRI features characteristic of ovarian granulosa cell tumors were the polymorphous morphology, an intense enhancement to the myometrium, restricted diffusion, and the presence of intraparenchymal hemorrhage.
A Case Report of Accessory Breast Cancer in the Anterior Chest Wall

Published: July 2022

We present and discuss a case report of a 70-year-old patient with a primary carcinoma in accessory breast tissue in the anterior chest wall. Accessory breast tissue has a reported incidence of 0.3% to 6% in the general population, resulting from an incomplete involution of the mammary milk line. It usually presents as a palpable mass. The most frequent localization of accessory breast tissue and its possible pathologies is the armpit, although it can occur in the inframammary region and rarely on thighs, perineum, groin, or vulva. The diagnosis is mainly clinical, but imaging findings may be helpful to confirm the suspicion because they are similar to breast cancer within the breast. Ultrasound is the most useful radiological method to evaluate these lesions and guide the suspected diagnosis together with the clinical presentation. Treatment should be performed under the same principles as breast cancer, both surgical and systemic therapies. The prognosis of accessory breast carcinoma may be poor in cases with delayed diagnosis compared to native breast cancer.
Implications of the 8th TNM Classification on the Bronchoscopist, a future perspective
Authors: Shakya Sabnam , Sahni Sonu , Assallum Hussein
Published: July 2022

Primary lung malignancy remains the leading cause of cancer related deaths globally. A better understanding of the disease process with advancing diagnostic modalities has led to a change in the standard of care. Endobronchial ultrasound (EBUS) with transbronchial lymph node needle aspiration allows for mediastinal and hilar lymph node sampling for accurate staging and prognostication. In the latest 8th edition of the TNM classification, several changes were made including redefining T based on size, redefinition of metastasis (M) and changes were made to stage groupings. Nodal staging has remained the same as of the 7th edition of the TNM classifications. In this review, we are reemphasizing the importance of the extra step of nodal staging and its clinical significance. Furthermore, we highlight the necessity of more aggressive nodal staging using EBUS-TBNA in stage 1 lung cancer.
Alcoholic Cardiomyopathy: Where do we stand?
Authors: Romani Andrea
Published: July 2022

The effect of alcohol consumption on cardiac and cardiovascular functions remains a point of contention in the medical field. The consumption of low or moderate amounts of alcohol has been largely associated with having beneficial effect on cardiac contractility and the cardiovascular system as a whole, owing to the detected vasodilatory effect exerted by the alcohol, and the reduction in mortality documented by several studies. In contrast, excessive alcohol consumption results in negative outcomes in both men and women, with cardiac arrhythmias and atrial fibrillation, abnormality in cardiac contraction leading to heart failure, and dilated cardiomyopathy, and overall cardiovascular dysfunctions, including hypertension. The main points of contention are two-fold: the dose of alcohol at which its perceived beneficial effects disappear and proper cardiac and cardiovascular functions become progressively impaired, and how to clinical and therapeutically address cardiac and cardiovascular pathologies in chronic alcoholics to ameliorate their general conditions and their prognosis. The present review aims at providing the reader with a general understanding of the effects of alcohol on the cardiovascular system and the pathophysiological mechanisms that lead to the most common cases of cardiac dysfunction, and highlight the current guidelines for treatment of alcoholic cardiomyopathy to ameliorate clinical presentation and prognosis in alcoholic patients.
Comparison of the Degree of Deconditioning in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Patients with and without Orthostatic Intolerance
Authors: Campen Linda , Visser Frans
Published: July 2022

Background: Orthostatic intolerance (OI) is a core finding in individuals with myalgic encephalomyelitis /chronic fatigue syndrome (ME/CFS). Deconditioning is often proposed as an important determinant for OI. Deconditioning can be objectively classified using the predicted peak oxygen consumption (%VO2 peak) values as derived from cardiopulmonary exercise testing (CPET) and OI can be objectively quantified using cerebral blood flow (CBF) changes during tilt testing. Therefore, if deconditioning contributes to OI, a correlation between peak VO2 and the %CBF reduction is expected. Methods and results: 18 healthy controls (HC) and 122 ME/CFS patients without hypotension or tachycardia on tilt testing were studied. Deconditioning was classified as follows: %VO2 peak ≥85%= no deconditioning, %VO2 peak 65-85%= mild deconditioning, %VO2 peak<65%= severe deconditioning. HC had higher %VO2 peak compared to ME/CFS patients (p<0.0001). ME/CFS patients had significantly larger CBF reduction than HC (p<0.0001). No relation between the degree of deconditioning by the %VO2 peak and the %CBF reduction in ME/CFS patients was found. Moreover, we separately analyzed ME/CFS patients without an abnormal CBF reduction. Despite equal CBF reductions compared to HC and large differences between these patients and the patients with an abnormal CBF reduction, cardiac index (CI) changes (measured by suprasternal Doppler) were significantly less compared to ME/CFS patients with an abnormal CBF reduction (p<0.0001) but larger than in HC (p=0.004). Despite these different hemodynamic findings, %VO2 values were not different between the two patient groups, argumenting again against the causative role of hemodynamic abnormalities in deconditioning. Conclusion: In ME/CFS patients without hypotension or tachycardia there is no relation between the %VO2 peak during CPET and the %CBF and %CI reduction during tilt testing, whether or not patients have an abnormal CBF reduction during tilt testing. It suggests again that deconditioning does not play an important role in OI.

Authors: Singh Mohita , Sharma Pankaj , Mahajan Anil , Tandon Vishal
Published: July 2022

Rheumatoid Arthritis is an autoimmune disease of unknown aetiology. The worldwide prevalence of rheumatoid arthritis is estimated to vary between 0.5 to 1.5% with geographic variation. The rationale behind relating vitamin D and RA is based on two facts. The first one is that there is evidence indicating that patients with RA have low levels of vitamin D. The second one is that the presence of vitamin D and VDR in macrophages, chondrocytes and synovial cells in the joints of these patients has also been demonstrated. The present study was designed to study the vitamin D status/ level in rheumatoid arthritis in males and females.

The study was carried on 100 subjects chosen randomly with 75 females and 25 males in age group of 16 – 65 years. Their demographic data was collected. Vitamin D level, rheumatoid factor assay and ESR were analyzed.

Higher level of disease activity as measured by DAS 28 score was associated with vitamin D deficiency. Females reported higher values for ESR, DAS 28 score and lower levels of vitamin D level as compared to males.

Vitamin D deficiency was positively associated with increase in DAS 28 score and rheumatoid arthritis (RA). Female sex had more preponderance for RA development. Rheumatoid factor had no gender preponderance.
Fracture neck of femur in severe coxa-vara – Challenging management in an Achondroplasia patient
Authors: Kumar Vishnu Senthil
Published: July 2022

Achondroplasia is a skeletal dysplasia of autosomal dominant inheritance. Fibroblast growth factor receptor 3 mutation at p16.3 locus of chromosome 4 leads to inhibition of sub-chondral growth. Middle aged achondroplastic patient with left fracture neck of femur following a fall of heavy object. It was a challenging case because of coxa-vara and meticulous templating is needed.

38 year old male sustained fracture neck of left femur in severe coxa-vara. Closed reduction with 16 mm partially threaded cannulated cancellous screw perpendicular to native neck- shaft angle. At regular follow up, mild lysis was seen around the screw and implant removal was done. Now with neck of femur non-union, walking full weight bearing with walker. The future course included excision arthroplasty or custom made prosthesis.

Achrondroplasia characterised by defects in en-chondral bone formation leading to retarded cartilage growth. Literature search on peri-articular fracture management showed peadiatric disatal femur fracture fixed with percutaneous screws. In adult, neck of femur fracture is managed by percutaneous screw, DHS or prosthesis. Due to altered geometry of proximal femur DHS and Prosthesis was deferred.Early failure of CC screws in our case is due to perpendicular placement of screws which increased strain due to altered bio-mechanics.

Achondroplastic dwarfs live a normal life. They are prone to peri-articular fractures because of anatomical variations. We wanted to highlight the difficulties and importance of pre-op planning and implant choice of fracture fixation in an adult achondroplasia patient.

Published: July 2022

O Brasil se destaca na produção mundial de coco. Contudo, aproximadamente 80% do peso bruto do coco é considerado resíduo, o que, por sua difícil degradação, grande volume e descarte inadequado, gera problemas ao meio ambiente. O presente trabalho tem por objetivo analisar as características das cinzas geradas pela queima da casca do coco, produzidas no litoral sul de Alagoas, visando à aplicação como adição mineral em concretos. As cinzas foram caracterizadas através dos ensaios de Análise Granulométrica, Fluorescência de Raios X (FRX), Difração de Raios X (DRX), Análise Termogravimétrica (TG – Thermogravimetric Analysis) e Microscopia Eletrônica de Varredura (MEV). Nos resultados obtidos por DRX, quanto à composição química, os principais compostos identificados foram KCl, SiO2 e Ca2(SiO4). Para os ensaios tecnológicos no concreto, os percentuais adotados de substituição de cimento por cinzas foram de 3%, 5% e 7%. A consistência do concreto tende a aumentar quanto maior o percentual das cinzas incorporadas no concreto. A absorção de água foi maior quanto maior o percentual de cinzas incorporadas, variando de 5,85% a 7,56%. Quanto à resistência à compressão, houve aumento de 12,19% de resistência em MPa na formulação com substituição de 3% de cimento por cinzas. Conforme os resultados obtidos, pode-se concluir que existe viabilidade de utilização das cinzas produzidas como adição mineral no concreto nos percentuais abaixo de 5%.

Published: July 2022

O resíduo florestal é todo e qualquer material que resulta da colheita ou do processamento da madeira que possa permanecer sem utilização definida no processo. As cinzas advindas da queima de carvão têm sido amplamente utilizadas em pesquisas; trabalhos com o uso de cinzas de biomassa, no entanto, ainda são recentes. O objetivo desta pesquisa consistiu em verificar a viabilidade da inserção de cinzas no traço de um compósito cimento-madeira. Foram realizados testes físicos para a determinação das propriedades físicas, densidade, inchamento e absorção de água, sendo também avaliadas a inibição do cimento com os materiais adicionais e a temperatura de hidratação da mistura. Para as cinzas, foram realizados testes para a obtenção do seu teor, avaliação da composição química, análise da distribuição granulométrica e espectroscopia de infravermelho com a transformada de Fourier (FTIR). A mistura com a cinza apresentou resultado superior em relação à mistura sem a cinza, nas propriedades de densidade e inchamento, dando indícios de que a utilização da cinza de biomassa é recomendada na fabricação de materiais cimentícios compósitos com resíduo de madeira, pois pode contribuir com menor degradação do material, que será avaliado em testes de durabilidade na sequência deste estudo.

Published: July 2022

Este estudo assume como objeto o fenômeno da interação entre seres humanos e máquinas e seus sucedâneos a partir dos fundamentos da técnica, da ética e da estética. O estudo está contextualizado no horizonte contemporâneo do ciberespaço, considerando que o advento das tecnologias digitais e o avanço sem precedente dos inventos tecnológicos estabelecem desafios ao diálogo entre técnica, ética e estética que, se não são inéditos na história, têm graves implicações no desenrolar da experiência de desenvolvimento civilizatório promovida em esfera global. Revisando algumas fontes teóricas (especialmente na filosofia, nas ciências sociais e na literatura) que se dedicam – direta ou indiretamente – a essa problemática, a conclusão da análise trouxe a compreensão de que o progresso de qualquer civilização humana não se constrói apenas com o desenvolvimento da técnica e dos produtos tecnológicos que lhe são derivados: os tratos ético e estético são igualmente importantes para firmar práticas produtivas que não afetem as vidas que podem ser impactadas pelo saber fazer humano.
O amor nas entrelinhas: a tentativa do (in)dizível no conto “Para uma avenca partindo”, de Caio Fernando Abreu
Authors: Silva Rian Lucas Da , Aragão Jackelinne Maria De Albuquerque
Published: July 2022

Independentemente de definições, teorias e vertentes a respeito do amor, é de comum acordo que esse sentimento pertence à subjetividade do homem desde que se tem conhecimento da origem do mundo. Em virtude da complexidade que envolve essa temática, objetiva-se, no presente estudo, analisar a forma como o amor é representado, tomando, como objeto de análise, o conto do escritor gaúcho Caio Fernando Abreu intitulado “Para uma avenca partindo”. Nesse sentido, a análise se deu mediante pesquisa de abordagem qualitativa-interpretativa de viés bibliográfico, com referencial teórico voltado a áreas diversas, como a História e a Sociologia, e a alguns autores, entre os quais são citados Moreno e Lima (2015), Moreira (2013), Ângelo (2012), Machado (2006), Borges (2004) e Bauman (2004). Posteriormente às análises empreendidas, foi averiguado que o amor se encontra inserido nas entrelinhas das falas dos personagens, ou melhor, no (in)dizível, de modo que os sujeitos representados no texto literário se encontram imersos em uma ambientação marcada por uma partida, revelando a representação do amor posto como algo acabado em virtude de uma viagem. Por fim, foi observado também que o amor surge, inicialmente, a partir de três etapas que se complementam durante todo o desenrolar da narrativa, a saber: a confissão do narrador personagem, as lembranças vividas pelos sujeitos e, por último, o cuidado tido para com a companheira do homem.

Nanoparticles of porous silicon with incorporated europium and gadolinium ions were prepared by using mechanical grinding of electrochemically grown mesoporous silicon films followed with impregnation with rare earth ions from aqueous solutions. The photoluminescence spectroscopy of europium doped porous silicon nanoparticles allowed us to reveal narrow lines associated with the 5D0→7F4 transitions in Eu3+ ions. Measurements of the proton relaxation in aqueous suspensions of nanoparticles with embedded Gd3+ ions showed an effect of the shortening of both the longitudinal and transverse relaxation times. Potential applications of rare earth doped porous silicon nanoparticles as contrast agents in MRI and fluorescent labels in bioimaging are discussed.

Penelitian kali ini memiliki tujuan untuk mengungkapkan bagaimana manajemen sumber daya manusia di Biro Cahaya Samarinda yang terdiri dari: perencanaan sumber daya manusia, proses konsultasi bersama psikolog disana, melakukan proses pengaturan terhadap klien yang datang, seperti apa psikolog mendapatkan pelatihan, hambatan apa saja yang hadir  semenjak biro ini didirikan. Pendekatan yang digunakan dalam penelitian ini adalah penelitian kualitatif. Subjek dalam penelitian ini ialah psikolog Biro Cahaya. Data dikumpulkan melalui wawancara bebas yang mana langsung oleh pemilik Biro Cahaya Samarinda dan dokumentasi. Hasil penelitian menunjukan bahwa Biro Cahaya Samarinda hanya memiliki 3 psikolog termasuk pendirinya dan sudah cukup lama berdiri. Klien yang datang ingin konsultasi sebelumnya akan mengatur janji dulu dengan admin Biro Cahaya melalui online yaitu media whatsapp atau datang langsung ke biro dihari sebelumnya. Psikolog di biro hanya mampu melayani 2-3 klien sehari dengan satu klien satu psikolog. Adapun pelatihan yang didapatkan psikolog di Biro Cahaya mereka mencari pelatihan-pelatihan secara eksternal. Adanya hambatan di Biro Cahaya masih kurang sumber daya psikolognya sendiri, banyaknya klien yang berdatangan membuat Biro Cahaya hanya menerima 2-3 klien perharinya membuat Biro Cahaya harus mencari psikolog dari luar dan mengatur kehari selanjutnya karena kurangnya psikolog untuk bisa melayani klien, tidak menerimanya tenaga-tenaga bantuan dari luar seperti misalnya mahasiswa-mahsiswa magang yang berjurusan psikolog atau konseling di biro ini, membuat biro ini sedikit kewalahan dalam melayani klien. Dan tidak adanya pelatihan di internal Biro Cahaya sendiri untuk para psikolognya, para psikolog harus mengikuti pelatihan secara eksternal.

Introduction: Physical activity is a predictor of the health outcomes of the older adults, and many approaches have been introduced for its implementation. The present study aimed to investigate the effect of group physical games on life quality (QOL) of older adults at an adult day care center.
 
Methods: This quasi-experimental study was conducted using pre-test and post-test. Using convenience sampling, a total of 50 senior citizens above 60 years of age from two adult daycare centers of Babol and Amol in 2017 was placed in an intervention (25) and a control (25) group, respectively. The intervention group received physical games program twice a week for 6 weeks. The SF12 questionnaire was used to assess the QOL. The statistical analysis of the variables was carried out using t-tests, Wilcoxon, and Mann-Whitney tests at a significant level (P < 0.05) with SPSS software.
 
Results: The QOL scores of the participants in the intervention group, compared to the control group have significantly improved (p < 0.001). The calculated difference for the quality of life of the intervention group was (d = 4.40±  2.36) being (d = 1.68±  1.74) and (d = 2.72±  1.51) in the physical and mental aspects, respectively.
 
Conclusion: Physical exercise program (especially stationary physical game) can improve the quality of life of the older adults both physically and mentally. Therefore, such activities can be used to improve the quality of life of the older adults.

Authors: Pengpid Supa , Peltzer Karl
Published: July 2022

Introduction: Dizziness may be associated with negative health outcomes. This study aimed to determine the associations between dizziness and mental and physical health outcomes in middle-aged and older community-dwelling adults in India.
 
Methods: Cross-sectional data from 72,262 individuals (≥ 45 years) of the Longitudinal Ageing Study in India (LASI) Wave 1 in 2017-2018 were analyzed. Dizziness was assessed with the question of having persistent or troublesome dizziness or light headedness in the past two years.
 
Results: More than one in seven participants (13.7%) reported past 2-years dizziness. In adjusted logistic, linear and Poisson regression analyses, dizziness was associated with worse self-rated health status, lower life satisfaction, major depressive disorder, insomnia symptoms and severe fatigue. Regarding physical health, dizziness increased the odds of pain conditions, cardiovascular conditions, chronic lung disease, functional limitations, fall history, hearing loss, impaired vision and higher number of medications currently used. In addition, in the unadjusted analysis, dizziness was negatively associated with cognitive functioning.
 
Conclusion: Dizziness was associated with six poor mental health and eight poor physical health outcomes. Findings support multidimensional management of dizziness in the general population.

Introduction: Aging is associated with biological changes and may lead to various cognitive behavioural disorders such as insomnia and depression. Non-pharmacological interventions with pharmacological therapies would be effective, economical, and safe. The present study compared the effect of muscle strength-range of movement (MSROM) training and digital game on insomnia and depression disorders in older women and men.
 
Methods: This was a quasi-experimental pre/post- intervention. After recruitment invitations and screening, 92 participants were randomly assigned into three groups including physical training (PT; n = 31), mental training (MT; n = 30) and control group (CG; n = 31). Insomnia and depression were measured by insomnia severity index and geriatric depression scale (short form), respectively. The training programs were held 3 days per week for 8 weeks. Physical training began with 25 minutes in the first week and finished with 60 minutes in the eighth week using Borg rating of perceived exertion within the desired 13 to 15 range. A mental game has been launched on Android operating systems on cell phones/tablets which consisted of 4 games with 3 levels. Differences in variables were assessed via Factorial ANOVA and Bonferroni post hoc test (p ≤ 0.05).
 
Results: The Bonferroni post-hoc test revealed significant decreases in PT compared with CG in men (p = 0.010) and women (p = 0.038) regarding insomnia. Furthermore, there were significant decreases in PT compared with CG (p = 0.005) and PT compared with MT (p = 0.003) in men regarding depression; Significant decreases were also observed through comparing PT with CG (p = 0.043) in women regarding depression.
 
Conclusion: Findings demonstrated that MSROM training improved moderate insomnia and mild depression compared to smart thinker training in older women and men regardless of gender.
