Deriving Upper Bound on Channel Capacity of LEO Satellite Communication Link at sub-THz Frequencies
Authors: Kumar Rajnish , Arnon Shlomi
Published: September 2022

The increasing demand in data rates and new emerging applications require that the future generation of satellite networks will be designed at sub-THz frequencies with ultra-broad bandwidth. At such frequencies, the satellite channel is impaired by the highly frequency dependent absorption of the signal by the gaseous atmospheric media besides the thermal noise from the sky, the ground, receiver circuit and molecular absorption noise thus, making it a highly frequency-selective channel. In this work, we derive a theoretical upper bound on the channel capacity of a LEO satellite communication link by optimizing the power spectral density (PSD) of the transmitted signal considering the physicla aspects of THz channel. We obtain a closed form expression of optimum transmitted signal PSD that maximizes the channel capacity of LEO satellite link as the elevation angle changes with the transmitted power held constant.

Entity modeling
Authors: Possemato Tiziana
Published: September 2022

In questo lavoro tratteremo il tema delle entità intese come oggetti del mondo reale (real-world object) e di come questo concetto sia utilizzato nell’ambito dell’entity modeling, quel processo di identificazione e modellamento delle entità che tanta parte occupa nei progetti di conversione dei cataloghi in linked open data. L’aiuto alla comprensione di cosa questo concetto esprima nell’ambito dell’universo bibliografico ci viene dalla programmazione orientata agli oggetti, che introduce il concetto di modellamento e gestione di un “oggetto” definendone uno stato e un comportamento. Ma per modellare un oggetto è necessario identificarlo e questo processo deve avvenire, spesso, trattando quantità imponenti di dati, non necessariamente omogeneamente strutturati: l’Entity Resolution è questo insieme di processi macchina che cerca di risolvere le ambiguità date dalla disomogeneità delle descrizioni riferibili alla medesima entità. L’adozione di queste pratiche, in ambito bibliografico, muove ancora l’orizzonte dell’azione catalografica, che già si era esteso verso la più generale metadatazione, verso quel web di dati che impone un nuovo modo di intendere gli oggetti e di trattarli: l’entity modeling si annuncia come il terzo passaggio generazionale nella gestione del dato bibliografico.
Conceptual and linguistic changes: document, resource, and item
Authors: Biagiotti Denise
Published: September 2022

The bibliographic universe has radically changed in a short time; the major innovations, mainly related to the digital environment, have had consequences in terms of terminology. This contribution offers an analysis of three specific international cataloguing terms: document, resource, and item. The terms document and resource constitute an example of terminological evolution; item, introduced in cataloguing by FRBR as the fourth entity of Group I, highlights the difficulties of transposition from one linguistic system to another, and the multiple terminological meanings linked to different disciplinary contexts.
Rule following
Authors: Cheti Alberto
Published: September 2022

The importance attached to subject indexing in library services, librarian awareness of its social role and practical purposes,attention to indexing practices and the use of catalogs: How are these elements reflected in the system of rules governingsubject indexing in Italy? What does “rule following”, to use Wittengenstein’s well-known expression, mean in our field?Why and how do we follow a rule? In which sense is following a rule a practice? How and in which conditions does therule relate to the practice and vice versa? Beginning with these questions, the main features of the Italian subject indexingrules are illustrated: explicit rules, based on linguistic criteria, contain justifications for why a given rule should be followedand should be sensitive to the use-context. All three of these features imply a relationship with practice; at the same time,the rules presuppose a social practice in which they are employed and express their pragmatic meaning. Thus, the indexingrules are manifested in the language of indexing through the means by which this language is used; that is, in the indexingactivity and in the use of catalogs. Hence, the call for libraries to attend to the pragmatic dimension of subject indexing.
Agrifood data processing in Italy: a conceptual model
Authors: Martorano Annantonia , Gonnelli Elena
Published: September 2022

Through the study and analysis of a precise economic sector, that of agribusiness, this contribution attempts to elaborate a replicable conceptual model that, in compliance with scientific methodologies, can contribute to the development of current archives, which will later be historical, capable of managing traceable and secure digital flows. In that absolute semantic individuality that characterizes each documentary complex, subject to "rules" of treatment only by productive affinities and common provenance characteristics, the application of standards has been a matter of discussion for the scientific literature. The example from which we wish to move concerns a specific category of Software Packages (LIMS) that are currently used in Italy by analytical laboratories and that implement integrated management of multiple data and processes.
АНАЛІЗ СТАТИЧНИХ ХАРАКТЕРИСТИК ВІДЦЕНТРОВОГО РЕГУЛЯТОРА РОТОРА ВІТРОУСТАНОВКИ ПРИ АНТИФЛЮГЕРНОМУ РЕГУЛЮВАННІ
Authors: Golovko V. , Kokhanevich V. , Shykhailov M. , Marchenko N.
Published: September 2022

Сучасні вітроустановки (ВУ) повинні надійно та безпечно функціонувати в широкому діапазоні швидкостей вітру, що потребує їх обладнання засобами регулювання обертів та потужності. При цьому в ВУ малої потужності пріоритетним є регулювання поворотом лопаті навколо її вісі в використанням відцентрові регуляторів, що зарекомендували себе як одні з найбільш простих та надійних засобів регулювання. Проектування даних регуляторів для ВУ має свою специфіку і повинно враховувати крім параметрів самого регулятора також параметри ротора. Запропоновані Г.Х. Сабініним математична модель відцентрового регулятора для флюгерного регулювання та співробітниками Інституту відновлюваної енергетики НАН України математична модель для антифлюгерного регулювання дозволяють розробникам визначити параметри відцентрового регулятора при його проектуванні.

В даний час технологічні можливості виготовлення лопаті дозволяють отримати профіль лопаті максимально наближений до розрахункового, тобто розширення лопаті від кінця до комеля до 1:4 і закруту до 30°, що потребує врахування кута між хордою лопаті і її вектором моменту інерції. В ряді робіт були запропоновані математичні моделі для флюгерного та антифлюгерного регулювання з урахуванням даного кута. Проведений в даній роботі аналіз статичних характеристик відцентрового регулятора ротора вітроустановки при антифлюгерному регулюванні за різних кутів між хордою лопаті і вектором її моменту інерції показав, що даний параметр впливає на точність регулювання і його необхідно враховувати при розрахунку параметрів регулятора. Так різниця в обертах регулятора для лопатей, коли кути між хордою та моментом інерції складають 0° та 20° та з урахуванням діапазону регулювання в 20°, складе 9%. При налаштуванні регулятора на номінальні оберти для його узгодження з аеромеханічною характеристикою ротора для ефективної роботи вітроустановки також є необхідним врахування кута між хордою лопаті і її вектором моменту інерції. Так відхилення від номінальних обертів регулятора і, відповідно, ротора без урахування закруту лопаті в 10° буде складати 8,3%, в порівнянні з лопаттю що немає закруту. Бібл. 12, рис. 10.

Published: September 2022

Завдяки екологічним перевагам вітрові технології та їх широке застосування є одним із перспективних сучасних напрямів генерації електричної енергії. У роботі представлено результати теоретичних і прикладних досліджень щодо впливу параметрів вітрового потоку регіону Полісся на вибір характеристик автономної системи електропостачання на основі вітроелектричної установки.

Зокрема, виведено аналітичні залежності для визначення: потужності вітрового потоку, коефіцієнта використання енергії вітру, електричної потужності, що розвивається вітроенергетичною установкою, та середньорічної кількості часу роботи установки. 

Прикладні дослідження відображені в графічній залежності коефіцієнта використання енергії вітру від швидкохідності вітрового колеса та залежності потужності вітроенергетичної установки і коефіцієнта використання енергії вітру від швидкості вітру. Також відповідно до номограми розподілу середньої швидкості вітру по місяцям за період з 2011 до 2021 року та відповідно до номограми щомісячної частини вітрів, придатних для потреб вітроенергетики, обґрунтовано вибір вітроелектричної установки малої потужності.

Використовуючи методи статистичного розподілу, а саме розподіл Релея, нормальний розподіл, за середнім значенням параметра (швидкість вітру) та емпіричну функцію розподілу, досліджено щільність імовірності швидкості вітру. Встановлено, що застосування розподілу Релея дозволяє підвищити точність обчислення на 18,8 % і 36 % в порівнянні з нормальним розподілом і розрахунком за середнім значенням швидкості вітру відповідно. За 100 % було прийнято значення енергії, отримане розрахунком за емпіричними даними. Під час розрахунків мали місце похибки, спричинені нерівномірністю добового використання енергії споживачем та імпульсним характером надходження енергії. З метою уникнення зазначених похибок надалі рекомендовано використовувати математичне та комп'ютерне моделювання.

Отримані розрахунки параметрів елементів системи автономного електропостачання на основі вітроенергетичної установки, адаптованої до характеристик вітрового потоку регіону Полісся, свідчать про можливість забезпечення в даному регіоні надійного та безперебійного постачання споживачам електричної енергії.

Published: September 2022

Introduction: Rhupus is the combination of manifestations of RA and SLE, meeting the respective classification criteria of these two pathologies. This uncommon clinical entity with a prevalence of about 0.09% was described by Toone in 1960. Objective: To prove the mutual exclusivity of RA and SLE in rhupus. Observation 1: This was a 40-year-old patient, without children, hypertensive on 10mg of nifedipine, followed for 10 years for RA on 15mg of methotrexate. Admitted for polyarthritis, discoid lupus lesions on the ears, facial erythema in vespertilio, oral ulcers, otherwise, the rest of the physical examination was normal. The biological finds hemolytic anemia (hemoglobin to 9.8g/dl), biological inflammatory syndrome (CRP to 101 mg / l), rheumatoid factors, antinuclear antibodies to 1/564 type speckled appearance, U1RNP, anti-Sm and anti-SSA / Ro 52 were positive and hypocomplementemia CH50 to 21.80 (N : 41-94 U / ml). By the classification criteria the diagnosis of rhupus was retained, 400mg of hydroxychloroquine added to his treatment for 6 months gave a favorable evolution. Observation 2: This was a 21-year-old Guinean student living in Dakar who had been treated for RA for 2 years with 15 mg of methotrexate. She consulted for photosensitivity, erythema in the décolleté and the anterior chest and persistent polyarthritis. Antinuclear antibodies at 1/198 in indirect immunofluorescence on Hep20-10 euroimmun slide, anti-double-stranded DNA antibodies at 640U/ml and anti-Sm at 9U/ml were positive. She received 15mg of methotrexate, 400mg of hydroxychloroquine and 10mg of Prednisolone for 6 months which gave a good improvement. Conclusion: Rhupus seems to be underdiagnosed, its existence is a reality to be understood to face the challenge.

Authors: Rahman Dr. Mohammad Khalilur
Published: September 2022

Introduction: Traumatic vascular injury is caused by explosions and projectiles which may affect arteries and veins of the limbs, and is common in wartime and RTA, triggering bleeding and ischemia. The increasing use of high-energy weapons in modern warfare is associated with severe vascular injuries. The peripheral arteries and veins of the extremities are among the most commonly injured vessels in both civilian and military vascular trauma. Vascular injuries are classified as contusion, intimal disruption, puncture, lateral disruption, transections with hemorrhage or occlusion, arteriovenous fistula, spasm, and pseudoaneurysms. Any kind of bleeding whether inside or outside of the body is a sign of vascular trauma. Symptoms of vascular trauma include bleeding, swelling and/or pain, bruising, and a lump beneath the skin (haematoma). Patients with emergency peripheral vascular injury are usually diagnosed clinically. Non-invasive tests may confirm the diagnosis and are useful in-patient follow-up. Invasive tests can document the lesion and extent of disease if angiogram, angioplasty, local fibrinolytic therapy, or surgical bypass is contemplated. With the change of time background, the treatment of vascular injury is also changing. Nowadays advanced medical equipment provides benefits to patients with vascular injuries. Meanwhile, traditional treatments are still playing an important role. If vascular trauma has not been treated in time, it may cause disability or even death, especially for limb vascular injury. There are several management options for traumatic peripheral vascular injury including some interventional and non-interventional therapies. The study aimed to analyze the Success Rate of different management options for traumatic peripheral vascular injury. Methods: This retrospective study was carried out among fifty cases who attended in the vascular surgery department at the National Institute of Cardiovascular Disease (NICVD) and casualty block, .....

Introduction: Hematuria is the presence of erythrocytes in abnormal amounts in the urine during urination, it is macroscopic if the number of erythrocytes is greater than 500 000 red blood cells / min. considered as a banal sign, particularly the endemic countries of Bilharzia, it remains a frequent reason for consultation and a concern in urology. A total of 71 patients met our inclusion criteria; the mean age was 54.28 ± 18 with extremes ranging from 11 years to 85 years. The sex ratio is 2.22 in favors of men, 70% of our patients had consulted for total hematuria and 49.3% in outpatient. The duration of evolution of hematuria was greater than three months in 42% of cases, cystoscopy was performed in 38% of patients and the selected diagnoses were dominated by bladder tumors (67.9%). prostate adenoma (14%), adenocarcinoma of the prostate (7.2%). Saline bladder irrigation was performed in 63.4% of patients for 1 to 3 days in 53%. The discharge of our patients was done after diagnosis and specific treatment in 38.4% of cases and in 25% of cases after the management of hematuria. Conclusion: Macroscopic hematuria affects twice as many men as women, bladder tumors and prostatic disease alone are responsible for almost all etiologies. Bladder irrigation and specific treatment play an important role in its management.

Published: September 2022

Pyoderma gangrenosum (PG) is a rare entity belonging to the neutrophilic dermatoses. It is an inflammatory dermatosis with a chronic evolution by relapses, often revealing an associated underlying disease. The location to the breast represents is unusual, poorly documented in the literature localization and whose diagnosis remains difficult to establish. We report the case of a 51-year-old female patient, with no particular pathological history, who presented for 4 months a painful ulceration of the left breast, of centrifugal extension measuring 9 cm of the great axis, with a hemorrhagic base, well limited by an inflammatory violaceous border with no other localizations and no notion of trauma. A skin biopsy revealed a dermal neutropilic infiltrate. The patient was given oral corticosteroid therapy at a dose of 0.5mg/Kg/day coupled with topical corticosteroids. The results were satisfying: the ulcer gradually healed and the pain reduced. Pyoderma gangrenosum is a poorly understood clinical entity, classically presenting with inflammatory and painful skin ulcerations. It may occur in a post-surgical or post-traumatic context defining the phenomenon of pathergy described in neutrophilic dermatoses. Treatment is mainly based on topical corticosteroids or in severe cases oral immunosuppressants and the treatment of the underlying pathology.

A Case Study: Consumer Behavior of Frozen Fruit in terms of Preferences and Purchasing Power
Authors: Putlia Grace
Published: September 2022

Frozen food or what is known as frozen food is the result of food preservation methods that are carried out by lowering the temperature to the freezing point, this aims to slow down the spoilage process. One published study found that frozen fruit was, in some cases, more nutritious. Of course, this is suitable when conditioned during a pandemic like today, because frozen fruit is more durable, of course, it can minimize the frequency of people going out to buy stock. But on the other hand, apart from the price of frozen fruit which tends to be more expensive, there is a paradigm in the community that fresh fruit is healthier than frozen fruit. Although it is undeniable that fresh ingredients have a high amount of nutrients at harvest, the nutrients will quickly break down when the food is picked, packaged, and displayed. These nutrients will break down even more when placed in the refrigerator. This research is a qualitative research with a case study design. A total of 23 informants as end consumers really helped the completion of this research. The results of this study found that the paradigm in society that fresh fruit is healthier than frozen fruit is still rolling down and down, on the other hand factors such as price are also another cause.

The effect of gender diversity on firm performance in Indonesia
Authors: Tania Keyi Sylvia , Hesniati Hesniati
Published: September 2022

This study investigates the relationships between gender diversity in the board of directors and firm performance. It also uses several control variables: education, age, tenure, board size, board meeting, firm size, firm age, and leverage. We examine the relationship between variables with several methods, such as descriptive statistic methods, correlation tests, t-tests, and hypothesis testing on 29 LQ45 companies from 2016-2020. Our finding shows that gender diversity on the board of directors significantly negatively impacts firm performance. Despite the negative research results, we still recommend that companies increase gender diversity on the board of directors because many studies state a positive relationship between gender diversity on the board of directors and firm performance. In addition, the small number of women on the board of directors is less capable of positively affecting company performance, whereas, in this study, the number of women in each company each year is relatively small. The limitations of this study are that the number of years studied is only five years and the measurement of gender diversity only uses one proxy.

Introduction: Cystic fibrosis is a genetic pathological condition, affecting chromosome 7, which encodes the CFTR protein. This pathology is characterised by abundant mucus production, which in turn leads to blockage of the airways and blockage of the digestive tract.
Objective: The aim of this literature review is to gather the largest available amount of information related to cystic fibrosis and analyse it in detail, indicating the results and expectations that have been had with the use of some drugs over time in patients with cystic fibrosis. It is also intended to mention updates of procedures and their effectiveness.
Methodology: a systematic and complete search was carried out using the Cochrane Library database, with the term Cystic Fibrosis. The documents found were in Spanish and English. Some articles were excluded due to lack of updated information.
Results: Inhalation Dornase alfa alfa is a useful drug for airway improvement and mucus viscosity reduction, as are bronchodilators. Pancreatic enzymes and ursodeoxycholic acid are beneficial in the gastrointestinal area, reducing intestinal symptomatology. In patients with diabetes, Insulin is preferred. Only glutathione has a beneficial effect in patients with cystic fibrosis. Rehabilitation and management of postural abnormalities is vital to improve patients lives. In patients with nutritional deficiencies, nasogastric tube placement or gastrostomy is preferred to improve their nutrition.
Conclusions: Cystic fibrosis is a disease that has an inevitable progression. The treatments studied here show that they only help quality of life and pulmonary and gastrointestinal functions temporarily. Further studies are needed to determine therapies that can significantly improve patients, both physically and psychologically; and who knows, some therapy or therapies that may lead to a cure for this disease.

Published: September 2022

The problem of the status of a foreign language in the context of actualization of practical training of students and graduate students and increasing demand by employers' professional foreign language competence of graduates of Russian non-language universities were raised. Foreign language for a modern graduate, for example, a technical university, no longer the passing discipline, which not yet so long ago could not remember after receiving a diploma, but an effective tool for solving professional tasks of various types, and often the key to building a professional career. The results of a critical assessment of the current system of foreign language training of students and graduate students in several dozens of non-language universities conducted by the authors of the open documentation laid out on the Internet showed its imperfection in terms of professionalization and led to the conclusion about the need to change primarily with the emphasis on communication. Initious training of students with their future professional activities, and the presence of prerequisites for this. The regulatory and legal framework necessary to conduct changes has already been formed, so the initiative of local changes in the system should manifest themselves on the ground by the universities themselves. The authors of the article describes corrective activities regarding the foreign language training of students of a non-language university related to clarifications or changes in the basic characteristics of education and / or organizational and pedagogical conditions for the implementation of specific educational programs for training students and graduate students of directions 22.03.02 Metallurgy, 22.04.02 Metallurgy and 22.06.01 Material Technologies Department Metallurgical Technologies and Equipment of the Nizhny Novgorod State Technical University named after R.E. Alekseev, and already proven its effectiveness. Among them: extension in practical classes in the language as a study within each of the levels and transition from a level on the level of training in the share of foreign language practical training associated with the implementation of students in individual types of work related to future professional activities and aimed at forming, consolidation, development of practical skills and competencies on the profile of the relevant educational program; conducting practical training on optional disciplines of foreign language preparation included in the curriculum is fully in the format of practical training, as well as the organization of practical foreign language preparation within the framework of the production practices of students on the sites of Russian and foreign organizations engaged in the profile of a specific educational program.

Published: September 2022

In patients with obesity or type 2 diabetes, the accumulation of lipotoxic by-products in cardiomyocytes leads to apoptosis and contractile dysfunction, eventually resulting in metabolic cardiomyopathy (MC). However, the underlying mechanisms remain unclear. Inb this study, a comparative proteome analysis was conducted to evaluate the differentially expressed proteins (DEPs) in the hearts of normal mice on standard diet (control group) and of high-fat diet (HFD)-induced MC mice (HFD group). We identified 90 DEPs unique to the control group and 18 DEPs unique to the HFD group. In 90 DEPs unique to the control group, only 74 DEPs were annotated in the gene ontology (GO) database. These annotated DEPs are involved in 114 biological processes, 68 molecular functions, and 174 cellular components. In 18 DEPs unique to the HFD group, only 14 DEPs were annotated in the GO database. These annotated DEPs are involved in 24 biological processes, 22 molecular functions, and six cellular components. Protein levels of two fatty acid metabolism-related enzymes, carnitine palmitoyltransferase 1B (CPT1B) and acetyl-CoA acyltransferase 2 (ACAA2), in the hearts of the mice in control group and HFD group were analyzed by immunostaining and Western blot. The results showed that the protein levels of CPT1B and ACAA2 were elevated in hearts of the mice in HFD group, which were consistent with the proteomic analysis. Our results reveal the differentially expressed proteome related to the progression of MC, providing a series of potential therapeutic targets for MC.
Invasive exotic plant monitoring at Fossil Butte National Monument: 2021 field season

Published: September 2022

Invasive exotic plant (IEP) species are one of the biggest threats to natural ecosystem integrity and biodiversity, and controlling them is a high priority for the National Park Service. The Northern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. This report represents work completed during the 2021 field season at Fossil Butte National Monument (NM). From June 26 to 29, 2021, we recorded a total of 12 different priority IEP species during monitoring. A total of 763 priority IEP patches were recorded along 61.9 kilometers (38.5 mi) of 22 monitoring routes. Summer cypress (Bassia scoparia) was detected for the first time on monitoring routes along the Main Park Road. The highest densities of IEP patches were detected in several drainages and one trail: Sage Grouse Lek Drainage (32.7 patches/km), East Red Hill Drainage (19.4/km), Moose Bones Canyon (19.4/km), Main Park Road (19.0/km), West Fork Chicken Creek (17.6/km), Chicken Creek (15.0/km), Smallpox Creek (13.5/km) and the Historic Quarry Trail (11.1/km). The Fossil Butte Northwest, Wasatch Saddle, and North Dam Fork of Chicken Creek drainages were the only routes free of priority IEPs in 2021. Cheatgrass (Bromus tectorum), creeping foxtail (Alopecurus arundi-naceus), and Japanese brome (Bromus japonicus) were the most widespread species. Creeping foxtail continues to increase parkwide and along the Main Park Road and southern drainages. The two brome species have declined somewhat since 2018, but these species can fluctuate widely based on precipitation. Flixweed (Descurainia sophia), whitetop (Cardaria sp.), and quackgrass (Elymus repens) all appear to have declined since 2018 and their previous highs in earlier years. Control efforts by park staff are likely helping to prevent some IEP increases in the park. Network staff plan to return to Fossil Butte NM for an eighth round of monitoring in 2023.

Retained placenta is the unborn placenta after 30 minutes of the childbirth. Factors that cause retained placenta include maternal age, parity, curettage history, history of cesarean section, history of endometritis, and placenta previa. According to WHO, retained placenta was the factor that contributed 15-20% of maternal mortality rate. In Indonesia, the incidence of retained placenta in 2015 was 40.3%. In East Java itself, the incidence was 53.7% in 2015. Furthermore, in the Hospital of Permata Bunda Malang City, the incidence was 30.7% in January 2018 alone. The aim of the study was to determine the relationship between curettage history and the incidence of retained placenta of birth mothers in the Hospital of Permata Bunda, Malang City. This study used a Correlation design with Cross- sectional approach. The population in this study were 95  mothers with a sample of 76 respondents who delivered the baby normally. The sampling technique implemented was the Simple Random Sampling. The method of data analysis was Chi-square analysis. Based on the result, it was found that 35 responden (46.1%) had a history of curettage, 39 respondents (51.3%) had retained placenta, and 26 respondents (34.2%) who had curettage history had retained placenta. The result of Chi-square analysis demonstrated p-value 0,001 (< α 0,05). Therefore, it can be concluded that there was a significant relationship between curettage history and the incidence of retained placenta.

According to Basic Health Research in 2014-2018, the achievement of exclusive breastfeeding in East Java is still below the target set by the Ministry of Health of the Republic of Indonesia. The lack of exclusive breastfeeding given by the mother can be caused by so many factors, one of them is the lack of support that mothers get from their environment, especially from their husband. This study was held to determine the correlation of husband's support in exclusive breastfeeding. Articles were collected through Google and PubMed using “Father’s role and exclusive breastfeeding”, and “Husband’s role in exclusive breastfeeding” as the keywords. Screening towards the articles was based on PEOS frameworks, which consist of 2 international articles and 7 national articles. From those articles, 4 articles have been accredited by SCOPUS, ISI, and ARJUNA. The analysis showed that there is a significant correlation of husband support in exclusive breastfeeding. Husband's support can give a significant effect on exclusive breastfeeding. From the analysis that has been done, 66.7% of the journal articles stated that there is a relationship between husband's support in exclusive breastfeeding, and the rest of them (33.3%) stated that there is no relationship between husband's support in exclusive breastfeeding.

The biggest use of contraceptives in Indonesia is 3-month injectable contraceptives, 3- month contraceptives containing Depo Medroxyprogesterone acetate (DMPA) where long-term use of DMPA contraception results in sex hormone deficiency so that the acceptor experiences sexual dysfunction in aspects of sexual desire (libido) and intercourse pain. The purpose of this study was to analyze the relationship between the long use of DMPA injectable hormonal contraceptives with the incidence of sexual dysfunction in acceptors based on literature studies. The study used is a literature study with the type of Systematic Mapping Study. Articles are taken from databases in the form of Google Schoolar and Elsevier. The population obtained from the database was 23 articles, then screened using the PEOS framework and obtained as many as 5 articles consisting of four national articles and one international article. The results of the analysis of 5 articles found that the duration of DMPA use >2 years was 52.6% and 61.8% experienced sexual dysfunction. The results of the analysis test on the five articles showed that there was a 100% relationship between the duration of using DMPA injectable contraception and the incidence of sexual dysfunction. DMPA injection family planning acceptors should pay attention to the duration of use to reduce long-term risk, one of which is sexual dysfunction.

Teeth with pulp necrosis, whether or not with periapical abnormalities, may be indicated for root canal treatment. Root canal treatment is a treatment carried out with the aim of removing infected dental pulp tissue, necrotic debris, and microorganisms. It aims to make the root canal sterile and can be filled with filling material so that a hermetic density is obtained in the apical area. Root canal treatment consists of three main stages (Triad Endodontics). The endodontic triad consists of preparation, sterilization and root canal filling. These three stages of root canal treatment are very important because not all root canal treatments end with success. The success of root canal treatment can be evaluated after a minimum of six months. Subjective, objective and radiographic examinations need to be conduct for determining the success of the treatment. Root canal treatment is said to be successful if the results of the three examinations are declared good. This type of research is descriptive research. The research method was carried out by subjective, objective and radiographic examination in the study sample who had performed root canal treatment in 2016 that met the criteria of the researcher. The results of the research are included in the table and interpreted with a percentage that is very low to very good. Based on this, it was concluded that the success rate of root canal treatment in non-vital teeth at RSGM University of Jember in 2016 was 54.54% and included in the sufficient category.

Coronavirus disease 2019 (COVID-19) has been declared as worldwide pandemic. The most common symptoms are fever, fatigue, flu-like syndrome and accompanied by respiratory distress. About 10% of patients with COVID-19 in the acute phase show manifestations in the eye, especially in the retina. The activity of the cell surface enzyme protein angiotensin-converting enzyme 2 (ACE2) is believed underlying the clinical manifestations in the eye. This study aim to describe the clinical findings of COVID-19 in the retina which serves as a reference for diagnosis. The study was carried out using the PRISMA method with the keywords "retinal findings in COVID-19", "ophthalmology finding", "retina" and "cotton wool spot COVID-19" with retinal manifestations as an outcome in the literature published in 2020-2021 with search using Google Scholar, SchiHub and Pubmed.  There were 14 literatures that matched the inclusion criteria. Involvement of the anterior segment of the eye such as conjunctivitis and keratitis are quite common. The retinal arteries and veins in COVID-19 patients are enlarged due to the inflammatory mediators. The width of the vein diameter is related to the severity of the disease. “COVID-19 retinopathy” has been proposed as a term to describe the appearance of cotton wool spots on the posterior pole of the retina associated with intraretinal hemorrhage without signs of ocular inflammation in COVID-19 patients. With fundoscopic examination, the clinical features of the retina of COVID-19 patients were cotton wool spots, flame shaped hemorrhages or microhemorrhages caused by an inflammatory process in the micro blood vessels in the retina.

Candidiasis is fungal infection caused by the Candida sp. generally by Candida albicans. Diabetes mellitus is one of the predisposing factors for C. albicans fungal infection. The risk of infection is increased in women with hyperglycemia which cause high blood sugar level in vaginal. This condition providing an ideal place for fungal growth. This study aims to determine the description of the C. albicans in the urine of women with diabetes mellitus at Public Health Centre (I) East Denpasar. The sampling technique in this study used purposive sampling with a total sample of 30 urine of women with diabetes mellitus at Public Health Centre (I) East Denpasar in December 2021. The examination method used urine culture techniques on Sabouraud Dextrose Agar media, Gram stain and germ tube test. Based on the results of the examination of positive samples, the characteristics of colonies growing on SDA media were smooth, slightly raised on the surface, yellowish white in color, and smelled of yeast. On Gram staining, the results show the presence of oval-shaped blastopores, and purple in color and the germ tube test shows blastopores that form sprouts. In this study, 2 samples (7%) were positive for C. albicans and 28 samples (93%) were negative for C. albicans. Based on the results of the study, patients are expected to always maintain cleanliness (hygiene) in the genital area and maintain body immunity to reduce the risk of fungal infections.
