Promoting fruit and vegetable consumption during the COVID-19 pandemic – SportStudisMoveYou (SSMY): A randomized controlled trial
Authors: Weber Joram , Nigg Claudio R.
Published: October 2022

Background

The stay-at-home circumstances due to the global coronavirus pandemic have had some negative impacts on people's eating behavior.

Purpose

Therefore, this study attempted to improve fruit and vegetable (FV) consumption intention and behavior through an online video intervention based on the social cognitive theory.

Methods

Participants were recruited with a promotion video posted on social media channels. After consenting and completing a pre-survey, participants were randomly assigned to either a) the intervention group addressing FV consumption or the b) attention control group addressing physical activity. After two weeks, the participants completed an online post-survey.

Results

The participants (N = 82) were 77% female and 50% students; 95% chose German for the survey language, and 84% were from Switzerland. The mean baseline FV consumption intention was 3.05 (standard deviation: 1.03), and FV consumption was 4.64 (standard deviation: 2.06) portions a day. The analysis showed no significant change in FV consumption intention (F = (1, 78) = 0.02, p = 0.88, ηp2 = 0.00) or behavior (F = (1, 78) = 0.019, p = 0.89, ηp2 = 0.03) due to the intervention.

Conclusions

Plausible reasons why no significant effect was found were the brief intervention duration, the setting and insufficient tailoring. The lessons learned from this study are to plan better, tailor more to the needs of participants and carefully consider the goals before promoting an intervention.

Published: October 2022

In this paper, we analyze mean-field reflected backward stochastic differential equations when the driver has quadratic growth in the second unknown \begin{document}$ z $\end{document}. Using a linearization technique and the BMO martingale theory, we first apply a fixed-point argument to establish the uniqueness and existence result for the case with bounded terminal condition and obstacle. Then, with the help of the \begin{document}$ \theta $\end{document} -method, we develop a successive approximation procedure to remove the boundedness condition on the terminal condition and obstacle when the generator is concave (or convex) with respect to the second unknown \begin{document}$ z $\end{document}.

Published: October 2022

With the current developments of wind powered and wind assisted vessels comes the need for realistic ship model testing. Traditional test methods of free sailing models are somewhat limited by the difficulties to mimic the effects of the wind propulsion systems or at least for recreating them at the correct scale. Simulations are possible but time
consuming and they cannot grasp all aspects that free sailing models comprise. At the KTH Maritime Robotics Laboratory, a 1:30 scale model of Oceanbird was developed and equipped with numerous sensors to enable accurate and realistic measurements while sailing in unrestrained waters. The paper presents the model’s equipment and experimental results showing the abilities of the sailing demonstrator to gather high quality data for manoeuvring and aerodynamic studies. In particular, the definition of a zigzag manoeuvre for sailing ships is explained and results of tests are evaluated
regarding manoeuvrability and aerodynamics.
Sub-district costs and efficiency of a combination HIV/AIDS prevention-intervention in the Northwest Province of South Africa
Authors: Kevany Sebastian
Published: October 2022

Background: We reviewed a combination prevention program tostrengthen HIV prevention programming, community support mechanisms, community-based HIV testing, referral systems, and HIV prevention integration at the primary care level. The intervention included situational analysis to inform programming, community engagement and mobilization, and community-based biomedical and behavioral prevention. In support of PEPFAR’s country-ownership paradigm, we costed the combination HIV prevention program to determine data needed for local ownership. This research used costing and health system perspectives.Results: Cost per person reached with individual or small group prevention interventions ranged from $63.93 to $4,344.88. (cost per health facility strengthened). Personnel costs drove the intervention. This was true regardless of year or activity (i.e. wellness days or events, primary health care strengthening, community engagement, and wellness clubs).Conclusions: Labor-intensive rather than capital-intensive interventions for low-income settings, like this one, are important for treating and preventing HIV/AIDS and other health conditions sustainably. Over time, costs shifted from international cost centers to in-country headquarters offices, as required for sustainable PEPFAR initiatives. Such costing center evolution reflected changes in the intervention’s composition, including (1) the redesign and re-deployment of service delivery sites according to local needs, uptake, and implementation success and (2) the flexible and adaptable restructuring of intervention components in response to community needs.
Dyadic trauma and attachment: A monozygotic twin study assessing the efficacy of Somatic Experiencing®
Authors: Riordan Joseph P.
Published: October 2022

Orientation: Monozygotic twins offer a unique opportunity to examine the contagious nature of trauma in attachment dyads when one twin experiences trauma, but the other does not. Dyadic trauma is antagonistic to secure phylogenetic attachment (SPA).Research purpose: Attachment perturbations in trauma may be complicit in psychopathology. Somatic Experiencing (SE) is an effective treatment for post-traumatic stress disorder (PTSD), and attachment focused somatic experiencing (AF-SE) resolves dyadic trauma.Motivation for the study: Monozygotic twins may share a unique form of sibling attachment, described here as monozygotic attachment, characterised by elevated somatic congruence resulting in suboptimal attachment. The study was conducted to determine whether dyadic trauma is contagious and compromises SPA and whether SE and AF-SE are effective treatments to restore SPA.Research approach/design and method: A quantitative experimental approach was used to examine the nature of trauma in monozygotic attachment and the significance of trauma in relation to psychopathology. Smartphone devices were used to record seven autonomic variables pre- and post-treatment for both twins: heart rate variability (HRV), three HRV index variables, heart rate, sleep duration and sleep disturbances. Mean and small sample t-tests were applied to determine statistical significance.Main findings: Results conclude that trauma is contagious in attachment dyads and contributes to psychopathology. Somatic Experiencing is an effective treatment for trauma. The AF-SE resolves dyadic trauma restoring SPA as the antithesis of trauma.Implications for practice: Traumatology and attachment theory may be linked theoretically to resolve trauma.Contribution/value-add: Secure phylogenetic attachment offers a new category of attachment theory that defines trauma in dyads and its relationship to psychopathology.

Published: October 2022

Many divergent notions exist in theory and in practice about the formulation of the primary objectives of the enterprise. In theory it often is concerned with maximisation of wealth of either the common shareholder or the enterprise. In practice, on the other hand, the primary objective is often to make a satisfactory profit per share. How can these obvious differences be reconciled and what is the relationship between primary financial selection criteria in practice and their primary objective?
The role of glypican 3, arginase 1, and CD34 in differentiation between benign and malignant primary hepatic lesions
Authors: Mohamed Said Abu-Alkhair , Eldowik Yasser Mohamed
Published: October 2022

Background and aim

Benign hepatic nodular lesions mimicking hepatocellular carcinoma (HCC) may be categorized into hyperplastic nodular lesions, neoplastic nodular lesions, and miscellaneous nodular lesions. This study aimed to assess the role of glypican 3 (GPC3), arginase 1 (ARG-1), and CD34 in differentiation between benign and malignant primary hepatic lesions.

Materials and methods

This study included 48 cases, where 25 (52.08%) cases were diagnosed as primary HCC in the liver and 23 (47.92%) cases were diagnosed as benign hepatic lesions. Of the 48 patients, five (10.42%) cases were diagnosed as focal nodular hyperplasia, four (8.33%) cases were diagnosed as hepatic adenoma, eight (16.67%) cases were diagnosed as dysplastic nodule, and six (12.50%) cases were diagnosed as regenerative nodule.

Results

The sensitivity of GPC3 for differentiation between benign and malignant primary hepatic lesions was 80% and its specificity was 82.5%. The sensitivity of ARG-1 was 90%, and its specificity was 0.0%. The sensitivity of CD34 for HCC in the study group was 84% and its specificity was 91.3%.

Conclusion

There was high sensitivity and specificity of both GPC3 and CD34 immunostaining for distinction of primary HCC from benign hepatic mimicker lesions, whereas there was high sensitivity of ARG-1 in both benign and malignant primary hepatic lesions but with no specificity for differentiating the benign from malignant primary hepatic lesions.
Expression of matrix metalloproteinase-2 and survivin in pancreatic carcinoma
Authors: Mohamed Said Abu-Alkhair , Eldowik Yasser Mohamed
Published: October 2022

Background and Aim

Matrix metalloproteinase (MMP) is a member of the MMP family, which is a zinc-dependent endopeptidase that degrades all extracellular matrix components and vascular basement membrane. Survivin plays a leading role in the process of apoptosis regulation. Survivin is unique for its expression in human malignancies but not in normal adult cells. This study aimed to assess immunoexpression of MMP-2 and survivin in pancreatic carcinoma.

Patients and methods

A total of 25 pancreatic carcinomas were evaluated for immunohistochemical expression of MMP-2 and survivin. The expression was evaluated by immunoreactive score that combines the intensity of immunoreactions with the percentage of positive cells.

Results

In this study, 24/25 of the cases were pancreatic ductal adenocarcinoma (PDAC) and 1/25 was acinar cell carcinoma. Regarding tumor differentiation, PDAC included five cases of adenocarcinoma that were well differentiated, 16 cases were moderately differentiated, and three cases were poorly differentiated. Pancreatic carcinoma specimens showed positive cytoplasmic MMP-2 staining with high expression in 22/25 (88%) studied specimens ranging from 6/9 to 9/9 with high extent and intensity. Survivin staining with high expression was seen in 23/25 (92%) studied specimens, ranging from 9/12 to 12/12 with high extent and intensity.

Conclusion

MMP-2 and survivin expressions were positive in pancreatic carcinoma with various grades but negative in non-neoplastic parenchymal, acinar, and pancreatic ductal epithelium. There were significant positive relationships between MMP-2 and survivin expression and poor histological grade in PDAC (P<0.024 and 0.021, respectively).

Authors: Abdelhafez Aisha H.T.M. , El Shawaf Zainab A. , Abbas Mervat A. , El-Kader Mona A. Abd , Ibrahim Eman E.
Published: October 2022

Background and aim

4Low-grade inflammation plays an important role in type-2 diabetes and coronary-artery disease pathogenesis. YKL-40 is expressed in cells of innate immunity and is associated with endothelial dysfunction. The research aims to see if YKL-40 levels in the blood could be used as a diagnostic biomarker in type-2 diabetic patients. Additionally, to evaluate if there is a link between YKL-40 and ischemic heart disease in diabetic patients.

Patients and methods

The study was carried out on 75 Egyptian individuals (25 healthy persons as control, 25 type-2 diabetic patients without ischemic heart disease, and 25 type-2 diabetic patients with ischemic heart disease). Enzyme-linked immunosorbent assay was used to assess YKL-40 levels.

Results

There was a significant elevation in the levels of YKL-40 when patients with type-2 diabetes mellitus (T2DM) uncomplicated by ischemic heart disease and patients with T2DM complicated by ischemic heart disease compared with the control group (P<0.05). The optimal YKL-40 cutoff threshold was greater than 65 ng/ml. Furthermore, the level of YKL-40 was significantly higher (P<0.05) in patients with T2DM complicated by ischemic heart disease compared with individuals with T2DM not complicated by ischemic heart disease. The best cutoff point for YKL-40 to differentiate between those two groups was greater than 110 ng/ml.

Conclusion

In type-2 diabetic patients, YKL-40 could be a valuable diagnostic marker for vascular complications.

Published: October 2022

Aim:

To evaluate the prevalence of substance use disorder (SUD) and its association with the course and outcome of bipolar disorder (BD).

Materials and Methods:

A total of 773 patients with BD were recruited from 14 centers in different parts of India, and they were evaluated for the prevalence of comorbid substance dependence, course and outcome, subjective cognitive functioning, and disability.

Results:

About one-fourth (22.9%) of the participants had one or more substance dependence. In terms of specific substance of abuse, 136 (17.6%) had nicotine dependence, 80 (10.3%) patients had alcohol dependence, 13 (1.7%) had cannabis dependence, and nine (1.2%) had opioid dependence. Compared to those without comorbid substance dependence, those with a dual diagnosis (i.e., using at least one substance in a dependent pattern) were less educated, more often males, more often currently single, more often employed, had a lower number of depressive episodes per year of illness, had a higher number of manic and mixed episodes per year of illness in the first 5 years of illness, had a higher level of disability, and more often had a history of hospitalization and a history of receiving electroconvulsive therapy (ECT); also, a higher proportion of them had manic predominant polarity, more often had recurrent mania course, and were more often receiving a combination of lithium and valproate.

Conclusion:

About one-fourth of BD patients have comorbid SUDs, and presence of SUD has a negative impact on the course and outcome of BD.

Authors: Saxena Vrinda , Pal Arghya , Talukdar S. K. , Gupta Ravi
Published: October 2022

Objective:

Major depressive disorder (MDD) is often linked with a number of coexisting disorders with a relation that is poorly understood. The aim of this study was to find out the role of obstructive sleep apnea (OSA) in metabolic syndrome (MS) in subjects with MDD and to develop a model for factors leading to MS.

Methods:

It was a cross-sectional study conducted on 119 subjects. They were evaluated on sociodemographic and clinical parameters, Berlin questionnaire, and Quick Inventory of Depressive Symptomatology. Comparisons were made using appropriate statistics. Binary logistic regression was used to find out the role of clinical parameters in the development of MS.

Results:

A total of 34% with MDD had a high risk of developing OSA while 19% had metabolic syndrome. Among all clinical variables, antidepressant exposure in terms of total fluoxetine units, duration of treatment, and risk of developing OSA was found to be significantly more in patients with MS. A higher risk of OSA was found to have a higher likelihood to cause MS in patients with MDD.

Conclusion:

There is a high risk of MS and OSA in subjects with MDD. The increased risk of MS is contributed by an increased risk of developing OSA among patients with MDD. Cross-sectional design and limited generalizability are the major limitations of this study.
Gene therapy in hereditary retinal dystrophy
Authors: Chien Jia-Ying , Huang Shun-Ping
Published: October 2022

Hereditary retinal dystrophies (HRDs), such as retinitis pigmentosa, Leber's congenital amaurosis (LCA), Usher syndrome, and retinoschisis, are a group of genetic retinal disorders exhibiting both genetic and phenotypic heterogeneity. Symptoms include progressive retinal degeneration and constricted visual field. Some patients will be legal or completely blind. Advanced sequencing technologies improve the genetic diagnosis of HRD and lead to a new era of research into gene-targeted therapies. Following the first Food and Drug Administration approval of gene augmentation therapy for LCA caused by RPE65 mutations, multiple clinical trials are currently underway applying different techniques. In this review, we provide an overview of gene therapy for HRD and emphasize four distinct approaches to gene-targeted therapy that have the potential to slow or even reverse retinal degeneration: (1) viral vector-based and nonviral gene delivery, (2) RNA-based antisense oligonucleotide, (3) genome editing by the Clustered Regularly Interspaced Short Palindromic Repeat/cas9 system, and (4) optogenetics gene therapy.
Многовременные пропагаторы и условие согласованности
Authors: Sungted Siwaporn , Yoo-Kong Sikarin
Published: October 2022

Для нерелятивистской квантовой системы $N$ частиц волновая функция является функцией $3N$ пространственных координат и одной временно́й координаты. Релятивистское обобщение волновой функции зависит от $N$ временны́х переменных и известно как многовременная волновая функция. Ее эволюция описывается $N$ уравнениями Шредингера, по одному для каждой временной переменной. Чтобы система уравнений имела нетривиальное решение, $N$ гамильтонианов должны удовлетворять условию совместности, также называемому условием интегрируемости. В настоящей работе условие интегрируемости выражено в терминах лагранжианов. С помощью фейнмановского подхода к квантовой механике получена эволюция волновой функции по $N$ временным переменным. Уравнения этой эволюции совместны тогда и только тогда, когда $N$ лагранжианов удовлетворяют определенному соотношению, называемому условием согласованности, которое можно записать в терминах линии Вильсона. Условие согласованности порождает ключевое свойство эволюции волновой функции: независимость эволюции от траектории в пространстве временных переменных. Это дает основания предполагать, что необходимо учитывать все возможные траектории не только в пространстве зависимых (пространственных) переменных, но и в пространстве независимых (временных) переменных. С геометрической точки зрения условие согласованности можно рассматривать как условие нулевой кривизны, а многовременные эволюции - как согласованные параллельные переносы в плоском пространстве временных переменных.

Authors: Hibono Paulus Ronald , Wibisono Andito
Published: October 2022

Background: Post-traumatic arthrosis can occur subsequent to fracture of the distal femur related to residual malalignment or direct intraarticular injury. The presence of extra articular deformities either in the femur or the tibia with arthritis of the knee makes total knee arthroplasty (TKA) technically demanding. We report our initial experience on such complex knee arthroplastyCase Presentation: A 69-year-old female complained of progressive right knee pain, limited range of motion and obvious varus deformity of the right knee. She had a trauma history 13 years ago on femur side, operated and subsequent removal of implant 2 years after. Preoperative radiographs showed severe osteoarthritis on medial side and patellofemoral joint and malunion supracondylar and varus deformity. Total knee arthroplasty (TKA) was done using standard jig and equipmentConclusion: Correction could be possible to perform in majority of TKA for extraarticular deformities with good preoperative planning and templating, intraarticular bone resection and good soft tissue balancing both in flexion and extension.
Excellent Result of Revision Total Hip Replacement with Unexpected Metallosis
Authors: Farhadi Azmi , Hernugrahanto Kukuh Dwiputra , Sedar Jifaldiafrian Maharajadinda , Chilmi Mohammad Zaim
Published: October 2022

ABSTRACT Background: Metallosis is a syndrome of metal-induced synovitis with infiltration and accumulation of metallic debris into the periprosthetic structures, including soft and bony tissues. The debris causes a chronic inflammatory reaction due to joint instability, pain, osteolysis, implant loosening, or implant failure. The absence of a specific sign or symptom that indicates metallosis causes difficulty to diagnose.Presentation of Case: A 35-year-old female, history of primary left total hip replacement since seven years ago after avascular necrosis of the femoral head, presented with an eight-month history of left hip pain and limited range of motion. Radiograph results showed that there is no evidence of periprosthetic fracture or infection. The patient underwent a left revision total hip replacement, which revealed extensive necrotic black metal debris throughout the joint space.Discussion: Effective treatment requires a revision of total hip replacement to remove metal debris, bone graft area osteolysis, and to address the mechanical failure. The greatest possible of metallic debris during debridement is vital to avoid further osteolysis and prevent more extensive damage. Excellent clinical result was evaluated by Harris’s hip score in 18 months postoperatively.Conclusion: This case is a rare example of chronic metallosis presenting seven years following total hip replacement. Revision total hip replacement is the consensus management choice to avoid further destruction of the bone and joint capsule that can occur with metal-induced inflammation. Keywords:
Simultaneous Gradual Correction of Bilateral Late Onset Tibia Vara using High Tibial Osteotomy with a Mono-Axis Dynamic External Fixator: A Case Report
Authors: Sakti Triharto Banjaran , Siagian Natan Kevin Partogu , Kesuma Wongso , Siagian Andreas Marojahan Haratua
Published: October 2022

Tibia vara is a disease characterized by an abrupt angulation of the tibia into varus in the proximal end. This condition is caused by developmental growth defect of the proximal tibia physis. Tibia Vara can be classified into groups according to the age of the patient and the mainstay treatment is either acute or gradual surgical correction.A 21 year-old man with chief complaint bowing of the legs with leg pain since 3 years ago. Physical examination showed bilateral genu varum. The anteroposterior long leg standing X-Ray found that the deformity was of osseous origin at the proximal part of the tibia in varus position. Medial osteotomy of the proximal tibia was performed and a dynamic external fixator was installed. Gradual correction was performed at a rate of 1 mm per day. After 3 months, radiological evaluation showed good union and target angle of correction with acceptable mechanical axis was achieved. Patient had no complaint of pain or instability post-surgery.Gradual correction using external fixator provides a more flexible angle correction with lower risk of neurovascular compromises; but with its own disadvantage such as loss of correction after removal of the external device. In this case, gradual correction of late onset tibia vara using dynamic external fixator provides satisfactory outcome and enable a more fine-tuned angle correction.  It also potentially eliminate the need for a second surgery to remove the external device; thus reducing the length of hospitalization.
Functional and Radiological Outcome of Revision Total Hip Arthroplasty in the Indonesian National Referral Hospital
Authors: Sitorus Immanuel Panca , Dilogo Ismail Hadisoebroto
Published: October 2022

Background: Revision total hip arthroplasty (rTHA) rate has increased until 12-20% in the past few decades, despite the 95% success rate of THA approach in 10 years and 80% in 20 years. The most common causes of rTHA are dislocation, periprosthetic fracture, aseptic loosening, and periprosthetic joint infection. This study is aimed to describe the outcome of rTHA in Indonesia where there are limited types of revision implant and funding. Material and Methods: An analytic cross-sectional study was conducted on 31 rTHA in the Indonesian national referral hospital from January 2014 to December 2019. Data on the causes of rTHA was extracted. All subjects met the criteria underwent examination for functional outcome (Harris hip score) and radiological outcome (Harris or Engh criteria). All complications and outcomes after rTHA were identified. Results: Sixteen subjects met the criteria with the mean age of 48.13 (18.74). The most common causes of rTHA were dislocation, aseptic loosening, and perirosthetic joint infection (five cases each, 31.25%). The Harris hip score after complete rTHA was 79.42 (SD 6.14, range 70.50 – 91) with the mean follow up of 29.50 (SD 16.88, range 7 – 70 months). Only one possible loosening was identified in hybrid prosthesis (femoral component) from radiological exam. Three complications were observed, i.e. drop foot, recurrent dislocation, and extension knee contracture. Conclusion: Revision THA produces fair to good results in terms of functional outcome and no loosening in radiological exam. Revision THA is still a reliable technique to manage complications of THA.
Simultaneous Femoral Osteotomy and Primary Total Knee Arthroplasty in Patient with Severe Extra-articular Deformity : A Case Report
Authors: Brahmana Febrian , Hernugrahanto Kukuh Dwiputra
Published: October 2022

Correction of an extra-articular deformity of the femur and tibia during total knee arthroplasty (TKA) in advanced knee osteoarthritis (OA) is a technically demanding procedure. The challenge is in the implications of the femoral and tibial realignment osteotomy in both coronal and sagittal planes either as step-by-step or simultaneous procedure. We herein describe an unusual case of knee OA characterized by fixed severe varus knee deformity, tibio-femoral bowing, and lower limb internal rotation. The patient underwent distal femoral osteotomy correction accompanied by TKA to restore mechanical and rotational alignment at the same time. A standard primary posterior stabilized (PS) implant was used. The procedure successfully provided stability, restored alignment and delivered good functional outcome. This case highlights the arthroplasty surgeon’s challenges, especially those who work in limited facilities.
PROXIMAL TIBIAL SLIDING OSTEOTOMY AS AN ALTERNATIVE SOLUTION FOR PATIENTS WITH PROXIMAL TIBIAL BONE DEFECT AFTER NEGLECTED TIBIAL PLATEAU FRACTURES UNDERGOING TOTAL KNEE ARTHROPLASTY: A CASE REPORT
Authors: Riyadli Muhammad , Mulyadi Dicky
Published: October 2022

Trauma case to the joints, especially the knee joint is a difficult and challenging case to manage. In the initial conditions of trauma, this case may be relatively more rational to do reduction and fixation. However, in cases of delayed treatment, it will be a challenge for an orthopedic, where in the late condition, the knee joint will degenerate earlier and becomes early osteoarthritis. The therapy that can be done depends on the severity of the joint damage itself. One of the actions that can be taken in severe conditions of osteoarthritis is Total Knee Arthroplasty (TKA). But if the defect is very large, a special additional tool is usually needed, which will also be more expensive. We report a 51 years old female patient with secondary osteoarthritis and severe depressed in the medial proximal tibia due to neglected tibial plateau fracture. The patient had a total knee arthroplasty performed with an oblique osteotomy on the medial side of the tibial plateau and shifting it proximally to cover the defect area. The operation went smoothly and the implant used was a primary Posterior Stabilized (PS) TKA implant without metal augmentation. After the procedure, the patient's knee is reassessed. There was improvement in knee deformity, with good stability and full range of motion of the knee. The purpose of this paper is to demonstrate a sliding osteotomy technique for medial proximal tibia in Total Knee Arthroplasty, with the hope of being an alternative solution and reducing additional costs for osteoarthritis cases with a severe defect in the medial proximal tibia.

Published: October 2022

Tragedyanın bir tiyatro biçimi olarak tespit edilişi Aristoteles’in Poetika’sıyla başlar, ancak trajedi teorisi Poetika’nın yazıldığı M.Ö. 4.yy’dan bugüne gelen süreçte büyük oranda değişmiş ve dönüşmüştür. Söz konusu dönüşüm, tragedyanın biçimsel özellikleri kadar trajik olanın kavramsal karşılığı ile de ilintilidir. Bu çalışmada, tragedyanın öz’sel nitelikleri ile bunların modern trajedi teorisindeki yeri, Ingeborg Bachmann’ın “Manhattan’ın İyi Tanrısı” adlı oyun metni üzerinden araştırılmıştır. Bunun için öncelikle, tragedyayı oluşturan temel öğeler, bu öğelerin kurgulanış biçimleri ve trajik olanın anlam bağlamı incelenmiştir. Ardından, trajedi teorisinin geçirdiği modernist evrim ve bunun sonucu olarak yaşanan anlam çoğullaşması mercek altına alınmıştır. Antik trajedi ile modern trajedi arasındaki belirgin farklılıkların bulgulanması ile trajik olanın trajedi teorisindeki karşılığının anlaşılmasına çalışılmıştır. Son olarak ise, Manhattan’ın İyi Tanrısı oyunu elde edilen bilgi ve bulgular doğrultusunda incelemeye alınmıştır. Böylelikle, metnin hem antik trajedi ile hem de modern trajedi ile ilintisi saptanabilmiştir. Metnin biçimsel öğeleri ile kavramsal katmanları trajedi teorisi üzerinden irdelenerek, oyunun tür bazındaki tespiti gerçekleştirilmiştir. Sonuç olarak; hem Manhattan’ın İyi Tanrısı oyununun trajedi teorisi içindeki yeri ve konumunu anlaşılır hale getirmek, hem de bir tiyatro biçimi olarak trajedinin belirleyici niteliklerini açığa çıkarmak amaçlanmıştır.

Reforma de la negociación colectiva en el Real Decreto Ley 32/2021
Authors: Alfonso Mellado Carlos L.
Published: October 2022

En este trabajo se analiza el impacto de la reforma de la legislación laboral en materia de negociación colectiva introducida por el Real Decreto-Ley 32/2021, de 30 de diciembre.

En el trabajo se estudian las medidas introducidas especialmente en tres direcciones: la recuperación del papel esencial del convenio de sector en la determinación del salario, la recuperación del régimen de prórroga indefinida del contenido del convenio en defecto de que otra cosa se pacte, y la determinación del convenio aplicable en los casos de contratas entre empresas. Se hace una mención también de aspectos clave del sistema de negociación colectiva que no se han modificado y se analizan las intenciones de la reforma, valorando su orientación hacia la recuperación de derechos que se vieron afectados por anteriores reformas legales, especialmente la del año 2012.

Authors: Vela Díaz Raquel
Published: October 2022

El presente artículo analiza el actual tratamiento y regulación del teletrabajo en las Administraciones Públicas. Partiendo de sus antecedentes normativos, este trabajo aborda detenidamente la regulación actual del teletrabajo tras la inclusión del art. 47 bis en el EBEP. Posteriormente, se hace referencia a las regulaciones que han ido adaptándose y aprobándose en las diferentes Administraciones Públicas  -entidades locales y Comunidades Autónomas- como respuesta al mandato contenido en la citada regulación básica, prestando una especial atención al proyecto de Real Decreto por el que se regula el teletrabajo en la Administración General del Estado.
materialización de los derechos sociales y la marginalización de la Carta Social Europea en el Reino Unido
Authors: Ewing Keith D.
Published: October 2022

Este artículo se ocupa del Reino Unido y de la Carta Social Europea.  Examina la ratificación de la Carta y el cumplimiento de las obligaciones derivadas de la misma.  El artículo analiza el papel de los tribunales nacionales, así como del Tribunal Europeo de Derechos Humanos, en el cumplimiento, directo o indirecto, de las obligaciones de la Carta. También se abordan las implicaciones del Acuerdo de Comercio y Cooperación UE-Reino Unido tras el Brexit, que impone a ambas partes la obligación de cumplir con las medidas aceptadas de la Carta Social.  Tras exponer el papel que puede desempeñar el control parlamentario en la supervisión del cumplimiento de la Carta, el presente trabajo concluye con una sombría valoración del escaso grado de cumplimiento por parte de los sucesivos gobiernos británicos así como de los métodos ineficaces de su aplicación en el ámbito nacional.

COVID y guerra de Ucrania. A vueltas con la prohibición de despedir
Authors: Bohigues Esparza María Desamparados
Published: October 2022

La fuerza mayor provocada por la COVID-19 ha sido priorizada por el legislador como mecanismo de flexibilidad interna frente a la extinción de los contratos de trabajo, al igual que ha sucedido ahora con la guerra de Ucrania, y, por ende, la denominada prohibición de despedir. En este contexto, cobran especial relevancia aquellos supuestos de tránsito de un expediente de regulación temporal de empleo al despido, en los que la empresa presente pérdidas con anterioridad a la COVID-19, y ahora también, con anterioridad a la guerra de Ucrania.

Por ello, se hace necesario realizar un análisis normativo y jurisprudencial de los preceptos que regulan la denominada prohibición de despedir, con la finalidad de determinar, si se establece o no, una “prohibición de despedir”, y si la misma vulnera la libertad de empresa, y cuál debería ser la calificación jurídica atribuida al despido; nulidad o improcedencia, así como su ámbito temporal, material, y subjetivo. Asimismo, se analizará, de manera sucinta, la calificación del despido sin causa justa, en relación con los textos internacionales y el control de convencionalidad tras la ratificación por España de la Carta Social Europea revisada.
Régimen jurídico de los contratos formativos tras las modificaciones introducidas por la reforma laboral
Authors: Ramos Moragues Francisco
Published: October 2022

El RDL 32/2021, de 28 de diciembre vuelve a modificar el marco normativo existente en relación con los contratos formativos regulados en el art. 11 del Estatuto de los Trabajadores. El objetivo del legislador sigue siendo el mismo que en otras modificaciones normativas pretéritas habidas en esta materia, a saber: facilitar el acceso de las personas jóvenes al mercado de trabajo sobre la base de mejorar su formación y, por ende, su empleabilidad. El presente artículo tiene por objeto analizar cuáles son las principales novedades, su alcance y valorar en qué medida pueden contribuir al alcanzar el mencionado objetivo.
ELEMENTAL ANALYSIS OF CERAMIC ARTEFACTS FROM TANJUNG SIMPANG MENGAYAU SHIPWRECK IN SABAH

Published: October 2022

This article discusses the scientific analysis of ceramic artefacts recovered from a shipwreck at Tanjung Simpang Mengayau in Kudat, Sabah. The main objective is to determine the chemical composition of these artefacts to identify the materials and technology used in the production of the ceramics. Understanding the ceramic materials and technology will assist archaeologists and conservators to find the best methods for long-term and sustainable preservation of the ceramics heritage in Sabah. In total, 16 ceramic jar and celadon bowl sherds recovered from the Tanjung Simpang Mengayau shipwreck were analysed using X-ray diffraction (XRD) and X-ray fluorescence (XRF). The results revealed the presence of quartz and mullite minerals in the jars while quartz, mullite and cristobalite minerals were found in the celadon bowls, suggesting that both the jars and celadon bowls were made of kaolinite clay with added sand and limestone, but fired at different temperatures of 1,345°C and 1,470°C, respectively. Data gathered from this study is important not only for finding out and comparing the ceramic materials and production methods, but also to identify the possible origins of the Tanjung Simpang Mengayau ceramics.
MORE THAN FIVE DECADES OF RESEARCH ON UREASE INHIBITORS: A BIBLIOMETRIC STUDY

This study focuses on works related to urease inhibitors published from 1970 to 2021, gathered from the Web of Science database. This paper aims to examine the trends of research involving urease inhibitors, as there have been no centralised study that utilises bibliometric methods on the related research fields, methods used, as well as collaborations. The total number of publications examined in this paper after filtering is 574 and the number of review articles on urease inhibitors is on the low side considering other research topics published within the 51-year period. Experimental works are still the core method of gathering information on the usefulness of urease inhibitors in all fields within the investigated time span. From the mid-2000s, theoretical investigations emerged as a complement to experimental research, mostly in the form of molecular docking studies. As in the other fields of study, theoretical works have been accepted as part of research methods to examine the molecular interactions between compounds and urease. The main partners to consider for cooperation in this field of study are those in Pakistan, China, the United States, New Zealand and Spain as their institutions house researchers that are outstanding in the field and they produce articles that are highly cited.
GREENHOUSE GAS EMISSION AWARENESS AND FARE-PURCHASING BEHAVIOUR OF PASSENGERS IN AIR CARRIERS: A SOCIO-DEMOGRAPHIC ANALYSIS
Authors:   Nişantaşı University, ÖLÇEN OLCAY , ÖNLER BÜŞRA ,   Istanbul Gelisim University
Published: October 2022

Fares are one of the main financial resources for air carriers, and passengers’ intentions and attitudes can have decisive effects on their profitability. This paper is distinct because it underlines and discusses the awareness and attitudes of air passengers towards greenhouse gas emissions. This paper sheds light on passengers’ intentions to make extra payments to reduce these emissions with the help of a qualitative questionnaire. An analysis in terms of the socio-demographic variables of the respondents was carried out. It was found that the air passengers’ awareness and attitudes and fare-purchasing behaviour towards greenhouse gas emissions of air passengers are at a saturated level. It was also found that air passengers were ready to join sustainability activities via purchasing airfares. These findings are important for air carriers.

Implementation of water sector acquis in Ukraine
Authors: Vykhryst Serhiy
Published: October 2022

This paper provides an overview and analysis of the progress made by Ukraine in implementing Water Sector acquis listed in the EU-Ukraine Association Agreement. The paper concludes that for the most part the transposition of the respective Directives is complete. It is argued, however, that extra effort is required under the Nitrates Directive and the Drinking Water Directive. Notwithstanding tangible gains in the development of River Basin Management Plans, Flood Risk Management Plans and the adoption of the Marine Environmental Strategy of Ukraine, the implementation of the State Water Monitoring Program suffers obvious difficulties caused by the unprovoked and unjustified russia’s military aggression against Ukraine, especially in the areas of active warfare. Massive destruction of infrastructure including centralized water supply and sewerage systems is likely to hinder implementation of the Drinking Water Directive and the Urban Waste Water Treatment Directive in Ukraine.
State of the acquis communautaire in environmental matters in Ukraine: waste management
Authors: Roller Gerhard , Tevkun Tetiana
Published: October 2022

The article looks at the legislative efforts that have been taken to adapt waste legislation in Ukraine to European requirements. Despite the difficult situation due to the military aggression Ukraine Parliament has on June 20, 2022 adopted in second reading a new waste law. The law complies with both the Association Agreement and the EU Waste Framework Directive (WFD). Certain points go beyond what is required by the WFD. The law provides for strict liability for the owner of the land on which abandoned waste has been identified. The Law also defines technical requirements for incineration and co-incineration. In this respect, the draft already complies with the provisions of the EU Industrial Emissions Directive. The law also addresses the problem of transboundary movement of waste, although this issue is not a part of the Association Agreement or the WFD. The import of waste for disposal is prohibited. Also basic requirements of the EU Landfill Directive are covered. The evaluation of the Waste Management Law shows that Ukraine is on a good path to fulfil EU requirements.
