Contribuições da Demanda Efetiva à Teoria do Crescimento Puxado pelas Exportações sob a perspectiva do Novo-desenvolvimento
Authors: Cavessana Letícia Vieira
Published: March 2024

A partir do Princípio da Demanda Efetiva em Keynes, é quebrado o pressuposto clássico de que o crescimento da economia estaria limitado pela oferta de fatores de produção e que seria independente do nível de demanda, o que deu origem a modelos econômicos e políticos de diferentes conjecturas, inclusive teorias que defendem que o crescimento econômico de uma nação pode ser liderado pelo crescimento da demanda externa. Dessa forma, o presente estudo possui como objetivo expor e discutir o arcabouço teórico que colaborou para a construção do modelo de crescimento puxado pelas exportações, sob a perspectiva do Novo-desenvolvimentismo. Para esse fim, foi adotado o método dedutivo de análise, que inclui exposições detalhadas e discussões acerca das possíveis influências e contribuições.
A economia após a pandemia
Authors: Canuto Otaviano
Published: March 2024

O trabalho aborda algumas consequências duráveis da pandemia sobre as economias, ou seja, impactos da crise pandêmica com desdobramentos no futuro em economias nacionais em todo o mundo. Para além de perdas permanentes de produto e de um legado em termos de dívidas públicas mais elevadas, a pandemia deixará cicatrizes no mercado de trabalho, com efeitos sobre os estoques futuros de capital humano. A crise pandêmica também reforçou tendências prévias de remodelação da globalização, assim como acelerou a transformação digital. O trabalho destaca uma contradição em movimento entre, por um lado, o reforço da reorientação para dentro dos países e, por outro, a necessidade de coordenação política entre os países em muitas áreas. Lidar com futuras pandemias, mudanças climáticas, ciber-segurança, terrorismo, tendências migratórias e outras exigirá mais multilateralismo e não menos.

Published: March 2024

The aim of this study is to assess the effectiveness of human resource management (HRM) practices on employee contentment in the service sectors, focusing particularly on the Nigerian banking industry. A questionnaire was designed and distributed to 540 individuals working in service sectors, with a specific emphasis on the banking sector in Nigeria. Of these, 406 responses were collected. Statistical analyses including regression analysis using the Statistical Package for Social Science (SPSS) and one-way ANOVA were employed to test the research hypotheses.
The findings revealed that overall, HRM practices, including HR planning, staffing, training & development, and performance appraisal, demonstrated high levels of effectiveness. However, the efficacy of remuneration was deemed to be moderate. Employee contentment levels were found to be moderate as well. Importantly, a strong positive correlation was observed between the effectiveness of HRM practices and employee contentment. The report suggests that banks should enhance their financial compensation policies to improve employee morale and contentment. Additionally, it recommends conducting comparative studies between commercial banks and Islamic banks to gain further insights.

Emir Sultan'ın Nurbahşiliği Hakkında Kaynakların Tenkidi
Authors: Gökbulut Süleyman
Published: March 2024

Tarihimize yön vermiş ve manevî hafızamızda yer etmiş büyük önderler vardır. Aradan asırlar geçse de onların etkileri hâlâ canlıdır. Bunlardan biri de Emir Sultan (ö. 833/1429)’dır. O, Osmanlı kuruluş devri tasavvuf hayatının önde gelen şahsiyetlerindendir. Hem Yıldırım Bayezid (1389-1403)’in damadı olması hem de kurduğu tekkesiyle devlet erkânının yanı sıra halkın yaşamına da yön veren Emir Sultan’ın hayatı menkıbelerle örülmüştür. Kendisi hakkındaki tarihî bilgilerin azlığı bazı klasik biyografi yazarlarının ve modern araştırmacıların onun tasavvufî silsilesi üzerinde farklı bilgiler vermelerine sebep olmuştur. Bunların en başında onun bir Nurbahşî şeyhi olarak Anadolu’ya geldiği ve bu kolu yaydığı hususu gelmektedir. Fakat Nurbahşiyye’nin ve bu hareketin önderi Muhammed Nurbahş (ö. 869/1464)’ın pek bilinmemesi söz konusu müellifleri, Emir Sultan’ın Kübreviyye, Nakşibendiyye ve Halvetiyye’den hangisine bağlı olduğu konusunda tarihsel hatalara sürüklemiştir. Bu makalede tarih usulüne uygun bir şekilde kaynak tenkidi yöntemi kullanılarak öncelikle Emir Sultan hakkında kaleme alınan menâkıbnâmeler gözden geçirilecek, ardından onunla ilgili bilgi veren biyografi yazarlarına müracaat edilerek şeyhin tasavvufî bir silsilesi ortaya konulmaya çalışılacaktır. Kaynakların verdiği bilgiler tarihî ve tasavvufî açıdan tenkit süzgecinden geçirilerek bu söylemlerin hangi nedenlerle ortaya çıkmış olabileceği üzerinde değerlendirmeler yapılacaktır. Makalenin sonunda da Emir Sultan Dergâhı şeyhlerinden Lütfullah Efendi (ö. 894/1490)’nin, tarikatı “Buhâriyye” adıyla yeniden inşa etme çabalarına yer verilecektir.

Published: March 2024

Waste is a global problem that must be resolved so that the environment is well maintained, especially in developing countries such as Indonesia. A good understanding of waste will have an impact on optimal waste management. Waste banks are one way out in waste management so that what was originally useless becomes marketable. In its implementation, the waste bank must have data collection and transparency of customer waste data in real time. Technology is one of the main solutions to produce digital products that make it easier for people to access information accurately. By using the Convolutional Neural Network (CNN) algorithm, an image of image data can be predicted with good accuracy. Along with the development of technology today, various kinds of architectures are present, one of which is Mobilenet. This architecture has the ability to run machine learning models on mobile and IoT devices. Furthermore, the resulting model is quite good with an accuracy rate of 96% on Metal waste, 92% on Paper and Organic waste, 80% on Cardboard waste, 76% on Glass waste, and 72% on Plastic waste. The disadvantages that exist in this model when predicting with almost similar shapes and images that have many objects in them, the error will be greater so there is a possibility of error in predicting the results of the garbage image.

Authors:   Korean Institute of Smart Media, KIM Tai Hoon , NA In Seop
Published: March 2024

The construction of a stress measurement dataset plays a crucial role in various modern applications. In particular, for the efficient training of artificial intelligence models for stress measurement, it is essential to compare various biases and construct a quality-controlled dataset. In this paper, we propose the construction of a stress measurement dataset with quality management through the comparison of various biases. To achieve this, we introduce stress definitions and measurement tools, the process of building an artificial intelligence stress dataset, strategies to overcome biases for quality improvement, and considerations for stress data collection. Specifically, to manage dataset quality, we discuss various biases such as selection bias, measurement bias, causal bias, confirmation bias, and artificial intelligence bias that may arise during stress data collection. Through this paper, we aim to systematically understand considerations for stress data collection and various biases that may occur during the construction of a stress dataset, contributing to the construction of a dataset with guaranteed quality by overcoming these biases.

Türkiye’de neoliberal politikaların yaygınlaşmasına koşut olarak yerel ölçekte de kamu hizmetleri özel sektöre gördürülmeye başlanmıştır. Özelleştirilen başlıca alanlar arasında su, kanalizasyon ve taşıma hizmetleri bulunmaktadır. Özelleştirme deneyimlerinin birçoğunda hizmet kalitesinde düşüş, fiyatlarda artış görülmüştür. Bu sorunlara çözüm olarak yeniden belediyeleştirme gündeme gelmiştir. Bu araştırmanın amacı Türkiye’de yeniden belediyeleştirme örneklerden birisi olan Çeşme-Alaçatı bölgesindeki su hizmetleri sunumunun incelenmesidir. Kapsam, Çeşme-Alaçatı belediyeleri tarafından kurulan Çeşme-Alaçatı Çevre Koruma Altyapı Tesisler Yapma ve İşletme Birliği (ÇALBİR) aracılığıyla, Dünya Bankası yönlendirmesiyle on yıl boyunca özel sektöre gördürülen su sayacı okuma ve bakım-onarım hizmetinin yeniden belediyeleştirilme sürecidir. Araştırmada su hizmetlerine ilişkin dünyadaki uygulama örnekleri ve istatistikler incelenmiştir. Veri toplama tekniği olarak belge analizinin yanı sıra dört yarı yapılandırılmış görüşme yapılmıştır. Sonuç olarak, 6360 sayılı Yasa ile getirilen değişiklikler nedeniyle yeniden belediyeleştirilen Çeşme-Alaçatı su hizmetinin tipik bir yeniden belediyeleştirme örneği olmadığı, İZSU tarafından yerine getirilen hizmetlerin de klasik anlamda hizmetin bir kamu idaresi tarafından kendi olanaklarıyla doğrudan yerine getirilmesi olarak adlandırılamayacağı belirlenmiştir.

The spectral characteristics of the gyrotron with a megawatt power level in the 170 GHz range were modeled numerically. The calculations were carried out using the large particle method implemented in the KARAT code. The problem of three-dimensional modeling of the excitation of an asymmetric type mode was reduced to a 2.5-dimensional one. For this model, the presence of high-frequency fluctuations at the output of high-voltage power supplies, which determine the initial energy of electrons, was taken into account. The relationship between the shape and width of the radiation spectrum of the simulated gyrotron and the time dependence of the accelerating voltage has been studied. It is shown that the best agreement with experimental data is obtained by combining a relatively slow sawtooth change in particle energy with fast random fluctuations.

In the presence of chronic liver diseases, the post‑infectious period of COVID‑19 is difficult and potentially mortal. The impact of COVID‑19 on liver transplant patients has not been thoroughly investigated.
Objective —  to study the characteristics of the clinical course of COVID‑19 in liver transplant patients.
Materials and methods. At the end of December 2014, the first successful liver transplant operation in Georgia was performed at the Batumi Referral Hospital of the Autonomous Republic of Adjara. To date, a total of surgical interventions have been conducted, including 42 surgeries since the beginning of the pandemic. We analysed
The incidence of COVID‑19 infection in the cohort of 88 patients throughout their hospital stay after liver transplant and at the late postoperative period was analysed, as well as the characteristics of the clinical course of COVID‑19. To prevent COVID‑19 transmission within the hospital, a special protocol been developed: to ensure that the patient is safely isolated from contact with the source of infection. In the postoperative period, all patients received immunosuppressive therapy. To monitor the course of the disease, an interdisciplinary team was created, which consisted of a transplant surgeon, hepatologist, gastroenterologist, infectious disease specialist, therapist, and immunologist. The consultation was held at the place of residence and treatment of a patient.
Results. No cases of COVID‑19 infection were reported among patients at the hospital where the liver transplant was conducted. In the late period, COVID‑19 was registered in 17 (19.3%) patients, of whom one (5.9%) died from the infection. One patient was infected with COVID‑19 twice. We have identified four variants of the clinical course of COVID‑19: mild (23.5%) — without any symptoms except for mild respiratory symptoms; aggravated (41.2%) — mild respiratory symptoms and dyspeptic symptoms without significant changes in clinical diagnostic parameters; moderate (29.4%) — cough without sputum, hyperthermia for three days, decreased sense of smell, the presence of dyspeptic symptoms, increased average values of biochemical parameters (alanine aminotransferase, aspartate aminotransferase, γ‑glutamyl transpeptidase, alkaline phosphatase, total bilirubin); severe (5.9%) — development of multiple organ failure.
Conclusions. The implemented set of preventive measures ensured the patient’s protection from COVID‑19 infection in all cases during their hospital stay. In liver transplant patients.

Hemorrhoids are detected in 11% of the adult population, and they account for 42% of all rectal disorders. According to leading coloproctology centres, about 30% of patients with chronic hemorrhoids require surgical intervention. Each of these methods has its own advantages and disadvantages. None of them, however, provides minimally invasive intervention, which is the prevailing trend in modern surgery.
Objective — to conduct a comparative analysis and evaluate the outcomes of laser hemorrhoidoplasty and Milligan‑Morgan hemorrhoidectomy for patients with grade 2—3 chronic hemorrhoids.
Materials and methods. The study presents the treatment outcomes of 59 patients with grade 2—3 chronic internal hemorrhoids. The main group included 29 patients who underwent laser hemorrhoidoplasty. As a surgical treatment, the 30 patients in the control group underwent the Milligan‑Morgan operation using an Ethicon Harmonic ultrasonic electrosurgical coagulator.
Results. Treatment of hemorrhoids with a diode laser performed by a trained surgeon in accordance with the protocol and manner of execution offers a number of advantages compared to the traditional Milligan‑Morgan procedure. These advantages include a shorter operation time (p <0.001), reduced intensity and duration of postoperative pain after laser hemorrhoidoplasty (an average of 3.59±1.15 days), whereas after Milligan‑Morgan surgery, it was 5.60±1.22 days (p <0.001), decreased incidence of postoperative bleeding, and maintaining the radicality of the removal of the cavernous tissue substrate.
Conclusions. In the surgical treatment of grade 2—3 chronic internal hemorrhoids, laser hemorrhoidoplasty of internal hemorrhoidal nodes has undeniable advantages over the standard Milligan‑Morgan procedure.
A clinical case of successful treatment of acute phlegmonous appendicitis incarcerated in a hernial sac (Amyand’s hernia)
Authors: Haluzynska О. І. , Bilianskyi L. S.
Published: March 2024

Atypical localization of the vermiform appendix (VA) in acute appendicitis can lead to diagnostic and tactical errors in emergency abdominal surgery. The rarest and most atypical localization of the VA is within the hernial sac. This type of hernia is defined as Amyand’s hernia. The optimal scope of surgical intervention and access method (laparoscopic or open) for Amyand’s hernia have not been definitively determined. Questions remain regarding the necessity of removing an unaffected vermiform appendix, the approach to hernioplasty in destructive appendicitis, and the feasibility of using a mesh implant for hernioplasty. In cases of a sliding hernia, the destruction of the hernial sac can lead to difficulties with suturing the peritoneum, assessing the state of the strangulated testicle in men, and performing an orchidectomy. Therefore, it is imperative to establish an algorithm for the evaluation and surgical management of patients with strangulated inguinal hernias.
Objective —  present a clinical case of successful treatment of Amyand’s hernia with acute phlegmonous appendicitis incarcerated in a strangulated inguinal hernial sac and reactive orchoepididymitis, focusing on the selection of medical and diagnostic strategies to reduce the risk of complications.
The clinical case illustrates the effective management of a patient who presented with acute phlegmonous appendicitis and purulent orchoepididymitis. These abnormalities were found to be atypically localised within the sac of a strangulated right‑sided inguinal hernia, known as Amyand’s hernia. The necessary surgical procedures included an appendectomy and an orchidectomy.
Conclusions. Inflammation of the vermiform appendix in Amyand’s hernia can lead to various unpredictable purulent complications, such as acute typhlitis, purulent peritonitis, necrotizing orchoepididymitis, and Fournier’s phlegmon, necessitating extensive surgical intervention. The collective global and personal experience in treating Amyand’s hernia suggests the possibility of establishing standardised protocols for diagnosing and selecting a surgical intervention technique.
Comparative evaluation of different types of gastric conduits used for single-stage reconstruction during oesophageal cancer esophagectomy. Review
Authors: Shudrak Y. A.
Published: March 2024

In the treatment of local and local‑regional oesophageal cancer, esophagectomy takes centre stage. It is a complex procedure with a high rate of postoperative complications. There are different methods for oesophageal reconstruction, including colon interposition, supercharged jejunal interposition, and gastric pull‑up. Each has both advantages and disadvantages. However, a gastric graft is the preferred option due to the less traumatic nature of the operation. Currently, there are different methods for forming a gastric graft. Gastric conduits are classified based on their shape and can be categorised as whole‑stomach, sub‑total stomach, or gastric tube. Previous research on the functional characteristics of gastric conduits revealed that the most effective solution is a typical gastric tube. Due to its width (3—6 cm), the gastric tube limits its impact on lung movement within the pleural cavity, hence decreasing the incidence of postoperative respiratory complications (e.g., pneumonia). Pulmonary complications and anastomotic leaks are the main contributing causes of postoperative morbidity and mortality after esophagectomy. Other complications include technical and functional issues, as well as delayed problems such as anastomotic strictures and disease recurrence. However, the rate of complications remains between 20 and 80%, prompting oncologic surgeons to develop new methods for gastric conduit formation. Over the past 5 years, innovative methods using a special‑shaped gastric tube have been suggested. They appear to decrease the incidence of postoperative complications and enhance nutritional outcomes. This study aimed to evaluate the advantages of using special‑shaped gastric tubes in clinical practice as opposed to whole‑stomach and typical gastric tubes.
