Published: September 2022

Quality is an important thing to be discussed anywhere and anytime. Service quality is a determining factor in satisfying customers to achieve economic improvement. Based on previous research, it was found that there is a relationship between organizational culture and customer satisfaction. The quality culture in a laboratory organization reflects the overall organizational culture. This is in line with the ISO/IEC 17025:2017 which requires the application of a quality culture in a calibration laboratory. Price is also an element that needs to be analyzed to achieve customer satisfaction in a calibration laboratory. This study aims to analyze the effect of service quality on customer satisfaction by moderating organizational culture and prices in an ISO/IEC 17025:2017 accredited laboratory in the province of West Sumatra. The data was collected by distributing questionnaires to 93 respondents from government agencies and private companies in West Sumatra. Then, the data was processed using the method of Partial Least Square-Structural Equation Modeling (PLS-SEM). The results of this study indicate that service quality, organizational culture, and price have a positive and significant effect on customer satisfaction in a calibration laboratory. Moderation of organizational culture and price have no significant effect on the relationship of service quality to customer satisfaction in a calibration laboratory.

Günümüzde insanlar yemek ihtiyaçlarını restoranlarda karşılayabilmektedirler. İnsanların restoran tercihlerinde önemli faktörlerden bir tanesi hizmet kalitesidir. Restoran işletmeleri diğer işletmeler ile rekabette öne çıkabilmek adına sundukları hizmetin kalitesine daha fazla dikkat etmektedirler. Çünkü hizmet kalitesi hem müşterilerinin tatminini sağlamakta hem de müşterilerinin işletmelerini tekrar tercih etmelerinde etkili olmaktadır. Bu durum restoran işletmelerinin karlılıklarına da olumlu katkı sağlamaktadır. Bu doğrultuda araştırmanın temel amacı restoranlarda algılanan hizmet kalitesinin müşteri tatmini ve tekrar ziyaret etme niyeti üzerine etkisi olup olmadığını belirlemektir. Araştırmada nicel araştırma yaklaşımlarından ilişkisel tarama modeli kullanılmıştır. Araştırma Malatya merkezde bulunan restoranlardan hizmet alan müşterilerin katılımıyla gerçekleştirilmiştir. Toplam 391 katılımcıya anket uygulanmıştır. Elde edilen veriler SPSS ve Smart PLS istatistik programları ile analiz edilmiştir. Araştırma sonuçlarına göre hizmet kalitesinin müşteri tatmini ve tekrar ziyaret etme niyeti üzerinde doğrudan etkisi olduğu tespit edilmiştir. Müşteri tatminin tekrar ziyaret etme niyeti üzerinde doğrudan etkisi olduğu tespit edilmiştir. Ayrıca müşteri tatmininin hizmet kalitesi ile tekrar ziyaret etme niyeti arasında kısmi aracılık rolü olduğu bulunmuştur.

Authors: Li Lan , Zhang Weihua
Published: September 2022

Objective: To investigate the efficacy and prognosis of venetoclax combined with hypomethylating agents (HMAs) in the treatment of relapsed/refractory acute myeloid leukemia (AML). Methods: From June 2021 to February 2022, 14 patients with relapsed/refractory AML were treated with venetoclax combined with HMAs, among which nine patients were treated with venetoclax + azacytidine, while five patients were treated with venetoclax + decitabine. The efficacy of the treatments was observed, and the patients were followed up. Results: All patients received one to five courses of treatment, in which the median course of treatment was three; four cases achieved CR and another four achieved PR, with NR in six cases; there was no treatment-related death. There were seven deaths up to the end of the follow-up period, all of which were progressive deaths at the end of the disease, and the overall survival rate was 50.00%. All the patients experienced different degrees of nausea, vomiting, and myelosuppression (Grade II–IV), nine patients had Grade 3–4 hematological adverse reactions, and seven patients had infection. Conclusion: Venetoclax combined with hypomethylating agents is effective in the treatment of relapsed/refractory AML, with good prognosis, and some patients may even achieve CR. Although bone marrow suppression is serious with this combination, it is well tolerated.

Objective: To investigate the effectiveness of applying a multidisciplinary collaborative model for the diagnosis and treatment of patients with vertigo. Methods: The study was carried out in Xianyang Hospital of Yan’an University, in which 100 patients with vertigo were selected from April 2021 to April 2022 and were divided into two groups: the control group was under the single diagnosis and treatment model, whereas the experimental group was under the multidisciplinary collaborative diagnosis and treatment model, with 50 cases in each group. The diagnostic effects of the two groups were compared. Results: The diagnostic and therapeutic efficiency of the patients in the experimental group were 94% and 98%, respectively, while those of the patients in the control group were 78% and 82%, respectively, with a significant difference between the two groups (p < 0.05). The balance scores of the patients in both groups were low before the treatment, in which the difference was not significant (p > 0.05); after the treatment, the scores improved, with those of the patients in the experimental group being significantly higher than those in the control group (p < 0.05). Moreover, the satisfaction rate of patients in the experimental group (98%) was significantly higher than that of the control group (80%) (p < 0.05). Conclusion: The application of the multidisciplinary collaborative diagnosis and treatment model in the diagnosis of patients with vertigo is effective. The multidisciplinary model can improve clinical diagnosis, enhance the treatment effect, improve the clinical symptoms of patients, and increase the satisfaction of patient care. Hence, it is of high clinical application value.
HIRİSTİYAN AVRUPA’NIN CADILARINDAN SİNEMANIN MASUMLARINA DÖNÜŞÜM (NETFLIX FİLMLERİ ÖRNEĞİ)
Authors: ÖNER Yasin , SEYFELİ Canan
Published: September 2022

Makalenin konusu Hıristiyan Avrupa’nın cadılık fikrinin sinemanın gücüyle masumlara dönüşümüdür. Konu, Netflix’in orjinal yapımı olan Cursed (Lanetli), Luna Nera (Kara Ay) ve Akelarre (Kurtuluş Ayini) isimli filmlerle sınırlandırılmıştır. Bu filmler hem konunun anlaşılması hem de Netflix’in konuya bakış açısının ortaya konulması açısından yeterli düzeydedir. Burada temel amaç Hıristiyan dünyada cadılığa yüklenen anlamı ve bu anlamın sinemanın gücüyle masumiyete dönüştürülmesini açığa çıkarmaktır. Çalışmada önce Avrupa’da cadılık ve bunun Hıristiyanlıkla ilişkisi tarihsel verilere dayanarak ele alınmıştır. Film çözümlemesinde ise Avrupa’da eskiden yaşananla sinemadaki kurgusal yansıması arasında karşılaştırmaya dayalı yorumu hedeflenmiştir. Avrupa’da yaşanan cadı avı sürecinde Kilise, topluma zarar vereceğini düşündüğü cadılığın karşısında yer almış ve koruma içgüdüsüyle hareket ederek yıkıcı sonuçlara ve ölümlere sebep olmuştur. Sinema, suçluların masumiyetini açığa çıkarma yoluyla Kilise’nin geçmişteki bu değiştiremediği günahı ifadeye dökmekte ve itiraf mekanizmasını çalıştırmaktadır. Böylece bugünkü Kilise’nin itirafını ve masumiyetini mümkün kılmaktadır. Dolayısıyla çalışmada örneklem olarak seçilen üç filmin yayıncı platformu olan Netflix, bir yandan cadı olarak nitelendirilen insanların masumiyetini ortaya koymaya çalışırken diğer yandan Kilise açısından bir günah çıkarma eylemine girişmiştir. Burada verilmek istenen mesajlar neticesinde cadılarla birlikte Kilise de aklanmaya çalışılmış ve böylece dinden uzaklaşma eğiliminde olan modern insanla bağların güçlendirilmesi hedeflenmiştir.
PLOTINUS' THOUGHTS ON SEEING AND A METAPHORICAL APPROACH
Authors: AYDOĞAN Hüseyin
Published: September 2022

The relationship between the eye and seeing is one of the most studied areas of ancient philosophy. The Aristotelian relationship between the eye and seeing in the context of energeia assigned the eye the most competent and specialized position among the senses. On the other hand, the analogy Plato made between the good, the sun, the light and the eye is a more remarkable point. Plotinus, on the other hand, puts this question in a different focus in the Enneads: Do things that are far away appear to be smaller, and do things that are far removed from us seem to be at a short distance from us, while things that are near appear to be as large as they actually are and to have the distance from us that they actually have? Plotinos tries to find an answer to this question by explaining it in five different ways. As commentators like Kalligas and Armstrong have pointed out, he is close to the fourth explanation, which he compares to the relationship between color and dimness.

Through this trace, I will try to transfer the relationship between sight and the visible object to the relationship between thought and what is thought. In this way I will compare the distance between the visible and the sight with the distance between thinking and what is thought. At this point, I would like to focus on the word speculation, which is the scholastic equivalent of the word theoria. Finally, I will conclude that in the noesis activity without sense data, our knowledge of the eidos is most comprehensive and most distant from visible objects.
ANDIJAN UPRISING OF 1898. BY MATERIALS FROM THE PHOTO ARCHIVE OF THE EARTH SCIENCE MUSEUM, MSU
Authors: Maksimov Yuriy , Mambetova Alfia
Published: September 2022

The paper continues our series of publications telling about the results of the study of the photo collection collected by D.N. Anuchin in the late 19th - early 20th centuries and currently stored in the Earth Scence Museum of Moscow State University. In particular, this collection contains several dozen photographs by S.A. Melik-Sarkisyan (1866 - after 1913), taken by him in the Fergana region at the turn of the 19-20th centuries. On the basis of these photographs, historical literary and modern scientific publications, the causes, course and consequences of the Andijan uprising of 1898 are analyzed, as well as the biography of its leader Dukchi Ishan (1856-1898), a resident of the Min-Tube village in the Margilan district of the Fergana region, a follower of Sufism. Statistical data on the dead and wounded from both the Russian side (soldiers of the 20th Turkestan line-cadre battalion) and from the rebels, as well as on the penalties applied to the rebels, are given. Conclusions are drawn about the short-sighted policy of ignoring Islam on the part of Russian officials, which became one of the causes of the uprising. Dukchi Ishan’s negative influence on the local population mood is shown: the leader of rebels distorted the true Muslim values through falsifications and forgeries.

Schoolchildren, under the guidance of researchers from the Williams Research Center and accompanied by teachers of biology, geography, chemistry, learn to work independently with plants at the molecular genetic level, to isolate genes from plants, to study the processes of plant breeding and cultivation, to take care of experimental samples, and to observe changes in the growth of different varieties and hybrids plants...
Compaction trend and its implication in the overpressures estimate for the formations of the Colombian Foothills of the Eastern Plains
Authors: Mendoza Javier Oswaldo , Bueno Jael Andrea , Mateus Darwin , Moreno Luis-Eduardo
Published: September 2022

The main objective of this article is to raise a hypothesis to explain the main causes of overpressure in the formations of the Tertiary sequence for the stratigraphic column of the Colombian Foothill. For this purpose it was conducted an analysis of compaction trends from the Guayabo Formation until the unit C8 of the Carbonera Formation; in the area of foreland, where the tectonic affectation has been minimal. This analysis integrates the most representative basins modeling and tectono-stratigraphic events for such sedimentary sequence. It mapped overpressure areas, comparing them with geological parameters such as the subsidence, uplift, heat flow and speeds of sedimentation, to identify relations of these parameters with the overpressure of the area.  As the main result, it stresses the identification of different sedimentation and compacting rates for each tectono-stratigraphic sequence and its relationship with the overpressure of the formations. These differences are represented in specific equations presented in this work. One of the main conclusions relates the rapid uplift of the basin, occurred in mid Miocene and the lack of liberation of stresses; as one of the causes of the pressures that are currently observed.
ESTIMACIÓN DE PRESIÓN DE PORO A PARTIR DE VELOCIDADES SÍSMICAS.
Authors: Pérez Zayra , Ojeda German Y. , Mateus Darwin
Published: September 2022

On pore pressure calculations it is common to obtain a profile in a wellbore, which is then extrapolated toward offset wells. This practice might generate mistakes on pore pressure measurements, since geological conditions may change from a wellbore to another, even into the same basin. Therefore, it is important to use other tools which allow engineers not only to detect and estimate in an indirect way overpressure zones, but also to keep a lateral tracking of possible changes that may affect those values in the different formations. Taking into account this situation, we applied a methodology that estimates formation pressure from 3D seismic velocities by using the Eaton method. First, we estimated formation pore pressure; then, we identified possible overpressure zones. Finally, those results obtained from seismic information were analyzed involving well logs and pore pressure tests, in order to compare real data with prediction based on seismic information from the Colombian foothill.
STRAIGHT LINE METHODS FOR ESTIMATING PERMEABILITY OR WIDTH FOR A TWO-ZONE COMPOSITE CHANNELIZED RESERVOIR
Authors: Escobar Freddy Humberto , Montealegre Madero Matilde , Carrillo Moreno Daniel
Published: September 2022

Some well pressure tests conducted in channelized systems which result from either fluvial deposition or faulting, cannot be completely interpreted by conventional techniques, since variation in facies or reservoir width are not normally recognized yet in the oil literature. In this case, the corresponding equations traditionally used for single linear flow will provide inaccurate results. Therefore, they must be corrected. In this study, new equations to be used in conventional analysis for the linear flow (pseudo linear) regime formed during the acting of the anomaly - reservoir width or permeability - are introduced to the oil literature. The equations do not consider the simultaneous variation of both parameters. The proposed equations were validated by applying them to synthetic and field examples.
DESIGN AND APPLICATION OF FLOTATION SYSTEMS FOR THE TREATMENT OF REINJECTED WATER IN A COLOMBIAN PETROLEUM FIELD
Authors: Forero Jorge Enrique , Ortiz Olga Patricia , Duque José Javier
Published: September 2022

This document presents the application of a new flotation process, developed by Ecopetrol S.A., for the treatment of produced or residual production waters for injection. Recently, treatment costs of these waters have increased due to stricter quality specifications, especially in the content of suspended solids and emulsified oils, which should be eliminated to minimum levels (less than 5 ppm). In the same way, in the increase of the volumes to be treated, which have elevated –in some cases- more than 100 times. Considering the industrial results obtained, we observed that the application in this flotation process in production fields is a valuable treatment alternative, with advantages over the conventional processes, in terms of efficiency, energy, financial and of process.
Female athlete triad and relative energy deficiency in sport – endocrine changes and treatment in women
Authors: Witkoś Joanna , Hartman-Petrycka Magdalena
Published: September 2022

Introduction

Female athlete triad (FAT) it is a syndrome of three tightly interrelated components: amenorrhea, eating disorder, and osteoporosis. FAT syndrome has been re-evaluated and re-defined and the International Olympic Committee introduced a new relative energy deficiency in sport (RED-S) syndrome.

Aim

The aim of the study was to review the knowledge on the issues of endocrine changes occurring in FAT and RED-S, and treatment of those conditions on a basis of available literature.

Material and methods

This article was based on a review of the literature search in the electronic databases Medline (PubMed), EBSCO, ClinicalKey, and Willey Online Library, using the terms: ‘female athlete triad,’ ‘relative energy deficiency in sport,’ ‘FAT and RED-S and endocrine changes,’ ‘low energy availability (LEA) and endocrine changes,’ ‘FAT and RED-S and treatment and women’.

Results and discussion

LEA influences abnormal secretion of gonadotropin-releasing hormone (GnRH) and this leads to the disrupted follicle-stimulating hormone (FSH) and luteinising hormone (LH) secretion. Higher ghrelin levels inhibit secretion of GnRH and of adrenocorticotropic hormone (ACTH), growth hormone (GH), FSH and LH. A high peptide YY (PYY) results in a significant suppression of GnRH secretion. Hypercortisolemia occurring in athletes may directly affect reproductive functions. Lack of estrogen contributes both to disrupted mineralization of bones and to endothelial dysfunction.

Conclusions

Low energy levels found in female athletes diagnosed with FAT or RED-S syndrome significantly influence hormonal pathways, disrupting the function of their reproductive system, and this noticeably affects the overall health of sportswomen, influencing endothelial dysfunctions and bone mineral density.
The significance of race-related differences in anaesthesiological setting
Authors: Szymonek Katarzyna , Kędziora Bartosz , Tomczyk Hubert , Podlińska Iwona , Dariusz Onichimowski
Published: September 2022

Introduction

The human species shows a great variability. The differences involve culture, customs, appearance but they also come to include some biological or physiological aspects which have a potential bearing on the course of diseases and the effects of treatment. Over the recent years, the increasing globalisation and improved travel opportunities have resulted in a growing mass mobility. The arrival of people representing other ethnicities may pose a challenge to doctors traditionally offering treatment to individuals within ethnically homogenous societies.

Aim

The paper aims to present a comprehensive summary of state-of-the-art knowledge on race-related differences which may be of great importance for patient management in anaesthesiological setting.

Material and methods

This paper is based on the available literature.

Results and discussion

A literature review reveals a number of anatomical, pharmacokinetic and pharmacodynamic differences between the races. Moreover, particular ethnic groups show dissimilarities in the prevalence of some diseases requiring modifications in anaesthesiological management.

Conclusions

Prior to the commencement of treatment, patient’s ethnicity and the consequent differences in terms of physiology should be recognised and considered in the treatment to ensure it is conducted appropriately and safely.
The forgotten bomb: Ramussens’s aneurysm
Authors: Akkaya Hüseyin , Dilek Okan , Sözütok Sinan , Onan Hasan , Yılmaz Cengiz , Çelik Ümit , Gülek Bozkurt
Published: September 2022

Introduction

Rasmussen’s aneurysm is an inflammatory pseudoaneurysmal dilatation of a branch of the pulmonary artery adjacent to the tuberculous cavity. It often presents with hemoptysis resulting from its rupture. Massive hemoptysis seen in giant aneurysms is a rare but life-threatening complication of cavitary tuberculosis.

Aim

In this case, we aimed to present a case of giant rasmussen aneurysm that did not bleed and was diagnosed incidentally.

Case study

In this article, we present a female patient who was surprisingly diagnosed with Rasmussen’s aneurysm during her follow-up after having been admitted to our emergency department due to diabetic ketoacidosis, fever, and shortness of breath and not responding to tuberculosis treatment. She was diagnosed using multi-detector computed tomography angiography and underwent embolization with a percutaneous thrombin injection. On the day after the procedure, thoracotomy had to be performed because the pseudoaneurysm continued to show contrast enhancement on imaging. She was successfully treated with surgery.

Results and discussion

Although pulmonary artery aneurysms are rare, it should be kept in mind that they may be related to tuberculosis. Pulmonary artery aneurysms are large asymptomatic and can reach gigantic dimensions as in this case. Rupture of an aneurysm of this size can be predicted to be mortal. Percutaneous thrombin injection can be used for treatment. However, percutaneous treatment may recur in large aneurysms, in which case surgical treatment is curative.

Conclusions

Rasmussen aneurysm is very rare, and when it is asymptomatic, its diagnosis may be delayed until it reaches gigantic dimensions. Contrast-enhanced thorax computed tomography and especially multi-detector computed tomography angiography are helpful in diagnosis.

Enerji sistemlerinde kullanılan soğutucu akışkanların seçimi ve çevre dostu soğutucu akışkanların kullanımının önemi gün geçtikçe artmaktadır. Düşük küresel ısınma potansiyeline (KIP) ve ozon delme potansiyeline (ODP) sahip soğutucu akışkan seçimi çevre duyarlılığı açısından araştırmacılara önemli bir misyon yüklemektedir. Bu çalışmada, hidrokarbon soğutucu akışkan propan (R290) kullanılarak tasarlanmış bir ısı pompası sisteminin verimlilik analizi gerçekleştirilmiştir. Geleneksel ısı pompalarından farklı olarak tasarlanan bu sistemde; ısı geri kazanımı yapılarak, hem gerektiğinde kompresör çıkışındaki yüksek sıcaklıktaki soğutkanın hem de kondenser çıkışındaki soğutucu akışkanın ısısının depolanması ile bu durumlardaki verimlilik analizleri yapılmıştır. Yapılan analizlerde, ısı pompasının performans katsayısı (COP) değeri 2,75 olarak hesaplanmıştır. Geliştirilen modelde, defrost sürecince harcanan enerji miktarı elektrikli ısıtıcılı defrost yöntemine göre %63,6 oranında azaltılmıştır. Sistemin güneş enerjisinden de yararlanılarak daha da veriminin artırılabileceği öngörülmüştür.

Published: September 2022

Graphene platelets (GPLs) are frequently preferred as reinforcement material to improve the mechanical properties of many advanced technology ceramics, thanks to their superior properties. However, their reinforcement levels vary depending on whether they are homogeneously distributed in the matrix microstructure. This is generally controlled by the thickness (number of layers) of the GPLs. In general, single- or few-layer GPLs show high performance as reinforcement but are commercially expensive. This limits their large-scale use. This study aims to achieve the performance of the GPLs (GPLRef), which is determined to have a high mechanical reinforcement level but is quite expensive, by economically thinning other GPLs (C0-GPL) with similar platelet size but cheaper and thicker structure. For this purpose, the microfluidization technique, a new approach to the dispersion of GPLs, was applied. C0-GPL is exposed to 1, 2, 4 and 8 cycles of microfluidization process. Microfluidized GPLs were added to the SiAlON matrix at a ratio of 1.5 wt %, and the GPLs-SiAlON composites were sintered using the spark plasma sintering (SPS) technique. The platelet size of C0-GPL decreased as the number of applied microfluidization cycles increased. However, while this reduction in platelet size was not significant up to 2 cycles, it was very pronounced at 4 and 8 cycles. Raman analyses revealed that GPLs could be dispersed effectively for up to 4 cycles. After this point, the GPLs fragmented rather than thin as the number of cycles increased. GPLs slightly thinner than GPLRef could be obtained with 2 cycles of microfluidization (C2-GPL). Therefore, C2-GPL were more homogeneously dispersed in SiAlON matrix microstructure compared to GPLRef. As a result, both the through-plane and in-plane direction fracture toughness values of SiAlON matrix containing C2-GPL, which partially preserved the platelet size, were higher than those of GPLRef-SiAlON. The fracture toughness of SiAlON matrix composites containing 4 and 8 cycles of microfluidized GPLs were lower than that of GPLRef-SiAlON as an adverse effect of decreasing platelet size. It has been determined that the mechanical reinforcement performance of commercially expensive GPLRef can be achieved economically by applying 2 cycles of microfluidization to cost-effective C0-GPL.

Pati merupakan salah satu disintegran sediaan tablet yang berfungsi menghancurkan tablet sehingga zat aktif dapat dilepaskan. Tujuan penelitian ini untuk memanfaatkan pati hasil pregelatinasi dari buah sukun (Artocarpus altilis (Parkinson ex F.A.Zorn) Fosberg) sebagai bahan penghancur pada tablet eritromisin stearat (ERS). Penelitian diawali dengan mengidentifikasi kemampuan pati pregelatinasi buah sukun (PPBS) dengan melakukan uji swelling power dari pregelatinasi pati pada suhu 0, 60, 70, 80 dan 90oC. Pati yang memiliki swelling power yang paling baik dipilih sebagai bahan penghancur pada tablet ERS. Dalam penelitian ini dibuat 4 formula, yaitu F1 (ERS tunggal), F2 (ERS-PPBS, 9:1), F3 (ERS-PPBS, 7:3) dan F4 (ERS-PPBS, 1:1). Tablet dikempa langsung dengan alat kompaktibilitas (hydrolic press), selanjutnya tablet dievaluasi kekerasan, kerapuhan, kompaktibilitas dan waktu hancur tablet serta dikarakterisasi dengan scanning electron microscopy (SEM). Hasil penelitian menunjukkan bahwa penambahan pati pregelatinasi buah sukun dapat menurunkan nilai kekuatan tarik (tensile strength) campuran massa kempa. Fotomikrograf SEM menunjukkan penambahan pati pregelatinasi buah sukun dapat mencegah terjadinya sintering pada tablet ERS. Tablet campuran ERS-PPBS dapat meningkatkan waktu hancur dari pada tablet ERS tunggal. Waktu hancur paling cepat terjadi pada F4 yaitu pada 0,45±0,06 menit. Hasil ini mengindikasikan bahwa pati pregelatinasi buah sukun dapat mencegah terjadinya fenomena sintering dan meningkatkan waktu hancur tablet eritromisin stearat.
