Maskne: A Potential Misnomer?
Authors: Ilyas Muneeb , Hund William , Vasile Gabriella , Weiss Eduardo
Published: May 2021

The COVID-19 pandemic has led to the global adoption of mask wearing to contain he rampant spread of the virus. Certain occupational groups, particularly health care providers, must wear masks for prolonged periods. Alongside this pandemic emerged the use of the all-encompassing term “Maskne”, used to describe mask-related dermatologic pathologies. Although there is an increase in acne and acneiform lesions associated with prolonged facial mask use, “Maskne” may be a misnomer, causing non-dermatologic providers to misdiagnose patients with acne when they, in fact, have perioral dermatitis.

Published: May 2021

Malignant melanoma and particularly metastatic melanoma represent a diagnostic challenge due to the wide variety of histologic patterns, resemblance to benign entities, and extensive range of clinical presentations.  A high index of suspicion for melanoma is important for accurate diagnosis, especially when there is a previous history of malignancy.  Here, we present a patient with a history of melanoma and locally metastatic melanoma, who subsequently developed a nodule on his right forearm near the site of his previous melanoma excision.  Histologically, the melanoma appeared as granuloma annulare (GA) with benign cytologic features, but was identified as metastatic melanoma using SOX-10 immunohistochemical staining.  Other malignancies, including lymphomas, leukemias, sarcomas, and cutaneous metastases of internal malignancies, have mimicked GA and interstitial granulomatous processes.  Therefore, further immunohistochemical staining should be performed to assess for metastatic disease in the setting of a histological pattern that resembles a benign granulomatous process in a patient with a history of malignancy, including malignant melanoma.
True Serum Sickness, Pearls for Clinical Diagnosis
Authors: Lee Jack , Carr Patrick , Zlotoff Barrett , Guffey Darren
Published: May 2021

Background: True serum sickness is a type 3 hypersensitivity reaction against foreign antibodies, resulting in vasculitis and an acute clinical presentation. Historically reported with anti-venin, currently anti-thymocyte globulin in the context of transplant rejection prophylaxis remains one of the most common causes. The classic clinical triad of fevers, arthralgias, and rash is not consistently present, and the rash is often difficult to distinguish from typical drug reactions. However, certain unique findings can assist with diagnosis.
Case Presentation: We present a case of true serum sickness secondary to anti-thymocyte globulin featuring key exam and laboratory findings that enabled differentiation from other possible overlapping clinical entities, particularly drug reactions.
Conclusions: Marked temporomandibular jaw pain is an important early clue to the diagnosis. Linear serpiginous erythema along the plantar margin may be a specific feature when rash is present. To our knowledge, neither have been reported in similar clinical entities including serum-sickness-like reaction. Serum complement levels and direct immunofluorescence (if skin biopsy done) are useful for distinguishing true serum sickness from primary differentials serum sickness-like reaction and drug rash with eosinophilia and systemic symptoms.

Politik Bağlamda Yeni Eleştirel Teori: Özne ve İktidar Sorunsalları
Authors: AKDAĞ İnan
Published: May 2021

Toplumsal yaşamın çelişkili yapısı, eleştirel teorinin ortaya çıkışını, yazılı tarihin başlarına kadar götürmüştür. İnsanlık, çevresine, sürekli eleştirel bir çerçeveden bakmıştır. Bu bağlamda sistematik bakış açısı, zamanla, gelenekler yaratmıştır. Bu çalışmada amaç, sistematik eleştiri bakış açısı olan eleştirel teori ve o gelenekten gelen yeni eleştirel teoriyi incelemektir. Yeni eleştirel teori, 1960’larla birlikte ortaya çıkan, klasik eleştirel teori ile süreklilik içerisinde kopuş ilişkisi olan bir düşünce sistemidir. Post modern felsefeden temel alan bu bakış açısı, temelinde klasik eleştirel teorinin izlerini taşımış ancak klasik eleştirel teoriyi aşmıştır. Özne ve iktidar olgusuna bakış açısından yeni eleştirel teoriyi irdeleyen bu çalışma, klasik eleştirel teori ile yeni eleştirel teori arasında süreklilik içerisinde kopuş ilişkisi tespit etmiştir. Klasik teori, özne konusunda sınıfları ve onların arasında ayrıcalıklı özne olarak işçi sınıfını vurgularken yeni eleştirel teori, özne yerine özne konumlarını ve çoğul özneler olarak kimlikleri ikame etmiştir. Ek olarak, klasik eleştirel teori, iktidara gelmeyi savunurken yeni eleştirel teori iktidar olgusuna mesafeli yaklaşmıştır. Politik anlamda, klasik eleştirel teori, politik proje olarak sosyalizm hedefi koyarken yeni eleştirel teori, liberal demokrasi içerisinde reform arayışı içerisindedir. Sınıfsal kökleri itibarıyla, klasik eleştirel teori, işçi sınıfının düşünce biçimiyken yeni eleştirel teori küçük burjuvazinin düşünce tarzı olmuştur. Çalışmanın kapsamı, 1968 sonrası biçimlenen yeni eleştirel teoridir. Çalışmanın hipotezi, politik bağlamda yeni eleştirel teori, klasik eleştirel teoriden süreklilik içinde kopuş anlamına gelmektedir.

Authors: KALYONCUOĞLU Kamil Semih
Published: May 2021

One of the fronts that caused many economic and social problems for the Ottoman Empire during the First World War, in which the Ottoman Empire was a part, is the Caucasus Front. Shortly after the war started, the Russians attacked the Ottoman Empire from the Caucasus Front by sea and land, and the region was severely damaged. With the fall of the Caucasus Front, which had great hopes, the Russians started to bomb and capture the present Eastern Black Sea region, including Rize. Especially between 1916-1918, Rize, one of the important centers in the region, was badly affected economically by this war and the people of the region had to migrate to the west. In this study, the economic effects of the war on Rize were examined, and it was understood that Rize suffered severe damage both economically and socially.

Therapeutic targets in COVID-19 coagulopathy
Authors: Кондашевская М.В.
Published: May 2021

В обзоре представлены сведения о некоторых биохимических и клеточных механизмах патогенеза потенциально смертельного вирусного заболевания, получившего название COVID-19, провоцируемого вирусами из семейства коронавирусов SARS-CoV-2. Наибольшую опасность для жизни и здоровья пациентов представляет коагулопатия, обусловленная ответной реакцией на инфекцию — чрезмерной генерацией клетками пациента внеклеточных мембранных нановезикул (ВМН), которые могут спровоцировать активизацию гемостаза, приводящую к разрушительной полиорганной недостаточности. Вирусы также способны генерировать внеклеточные везикулы, называемые виросомами. Встраивая вирусные компоненты в свои виросомы, вирусы повышают персистентность за счет маскировки своих геномов, умножая вирусную инфекцию. В статье охарактеризованы свойства нейтрофильных гранулоцитов, активирующихся при инфицировании, и представлены сведения о молекулярных механизмах действия их компонентов при попадании во внеклеточное пространство. ВМН уже имеют практическое применение в качестве вакцинных носителей для иммунизации человека и животных против многих инфекционных заболеваний. В настоящее время актуальнейшей темой, обуславливающей большой практический интерес, стала роль ВМН в индуцировании иммунитета против коронавирусной инфекции. Охарактеризованы другие возможные терапевтические мишени.

Virus-induced coagulopathy is a typical example of the tight connection between inflammation and thrombosis. These two reactions are linked by pro-inflammatory agents, generated by activated neutrophils and their neutrophil extracellular traps (NETs). Extracellular membrane nanobubbles (EMNs), formed by a wide variety of cell types, have recently been identified as new entrants that play a key role in coagulopathy. EMNs directly and indirectly activate coagulation systems that lead to the further upregulation of inflammation and life-threatening organ dysfunction and thrombosis. EMNs are known to be responsible for the secretion, exchange, and transmission of important active biomolecules in COVID-19. Indeed, EMNs represent an essential mechanism in intercellular communication, and the roles of EMNs in infection and thrombosis have been increasingly recognized. The extracellular microvesicles of viruses, virosomes, represent a new type of infectious agents, which determines new therapeutic goals in solving the problems of controlling viral infections. Understanding the biological nature of all these microvesicles when studying them in vivo is of paramount importance for the development of diagnostic and therapeutic methods.
Türkiye’de Uygulanan Çevresel Etki Değerlendirme Sürecine Halkın Katılımının Fransa’daki Uygulamayla Karşılaştırılması
Authors: ÖZLÜ Rukiye Mehtap
Published: May 2021

Çevresel etki değerlendirmesi, mevzuatta belirlenen yatırım projelerinin çevreye etkisinin değerlendirildiği, alternatif çözümlerle irdelendiği ve gereken tedbirlerin alınmasının sağlandığı önemli bir planlama aracıdır. Çevrenin korunması için değerli olan bu araca halkın katılımı, hukuken düzenlendiği için hem idare hukuku hem de çevre hukuku açısından önemlidir. Zira karar verme yetkisi, idarede olsa da bu araç sayesinde çevreye ilişkin konularda halk, bilgilendirilmekte olup halkın görüş ve önerileri, idari karar verme sürecine dahil edilmektedir. Bu konuda dünyada yaşanan olumlu gelişmeleri yakından izleyen ülkemizde de çevresel etki değerlendirme aracı ve halkın katılımı, hukuki düzenlemelerde yerini almaktadır. Ancak çevresel etki değerlendirme sürecine halkın katılımı hem uluslararası hem de ulusal platformlarda nicel ve nitel yönden yetersiz bulunarak eleştirilmektedir. Bu durum, farklı devlet pratiklerinin incelenerek alternatif uygulamaların araştırılması zorunluluğunu doğurmaktadır. Bu sebeple çalışmada, Fransa’da uygulanan kamu anketi aracı Türkiye’deki uygulamayla karşılaştırmalı hukukun metotlarından faydalanılarak incelenmektedir. Çalışmada; iki ülke uygulamaları arasındaki benzerlik ve farklılıklar ortaya konulduktan sonra, Türkiye’deki çevresel etki değerlendirme sürecine halkın katılımının geliştirilmesine yönelik birtakım önerilerde bulunulmaktadır.

Bu çalışmada, etik liderliğin çalışanların bilgi paylaşımına olan etkisini kavramsal olarak ortaya koymak amaçlanmaktadır. Bu bağlamda, sistematik literatür incelemesi yapılmıştır. İncelemeler sonucunda, çalışanların bilgi paylaşımı davranışı sergilemesinde etik liderliğin güçlü etkilerinin olduğu belirlenmiştir. Ayrıca, detaylı literatür taraması sonucuna göre; lider-üye değişimi, örgütsel vatandaşlık davranışı, iş tatmini, öz-yeterlilik, lidere olan güven, algılanan örgütsel destek, içsel motivasyon, örgütsel bağlılık ve örgütsel özdeşleşme gibi bazı faktörlerin hem etik liderliğin çıktısı hem de bilgi paylaşımının öncülleri olduğu anlaşılmaktadır. Belirlenen bu ortak faktörler çerçevesinde literatürde yeterince ilişki kurulmadığı sonucuna ulaşılmıştır. Etik liderlik ile bilgi paylaşımı arasındaki ilişki, sosyal değişim teorisi, rol model teorisi, karşılıklılık teorisi, sosyal öğrenme teorisi vb. teoriler çerçevesinde ele alınmadığı gözlemlenmektedir. Bununla birlikte, kültürel farklılıkların etik liderlik ile bilgi paylaşım davranışı arasındaki ilişkiye olan muhtemel etkileri araştırmacılar tarafından incelenmediği de görülmektedir.

The Trade
Authors: Okikiolu Ayooluwanimi
Published: May 2021

This poem explores Canadian history, specifically Indigenous relations with North American colonizers. Originally a Native Studies 201 Winter 2020 creative assignment, this poem describes the advent and settling of European colonizers. The Trade discusses these events from a uniquely personal immigrant perspective and attempts to detail them. Finally, the poem explores the relevance of this history to the author’s own personal history and future experiences by looking back at history for an important quest: looking forward. Hopefully, this poem will inspire readers to reflect on their own identities in relationship to the past as well.
Self-regulation as a Mediator of Mindfulness and Physical Activity: A Narrative Review
Authors: Boyle Aaron , Mosewich Amber
Published: May 2021

Mindfulness is gaining increased attention as a means of increasing physical activity (PA) participation. Given that only 15.4% of adult Canadians currently meet the Canadian Physical Activity Guidelines (Colley et al., 2011), it is imperative to find ways to increase PA among adults. One way to do this is to promote self-regulation skills as self-regulation is among the top predictors of PA participation (Teixeira et al., 2015).  The purpose of this narrative review was to further understand the role of self-regulation as a potential mechanism by which mindfulness may be related to PA participation. Initially, 160 papers were identified by title for this review. After reading abstracts, 37 papers were identified as possibly relating to the topic of interest. Following full readings, 26 papers were included in the final review. Likely due to the novelty of this topic, there is limited research on the mechanisms by which mindfulness may be related to physical activity. Review of the literature suggests that self-regulation appears to be a promising mechanism by which mindfulness could improve physical activity participation (Shapiro et al., 2006; Samdal et al., 2017), as self-regulation has been shown to play an important role in behaviour change, however, other alternative mechanisms include improved self-efficacy, as well as improved satisfaction (Neace et al., 2020; Tsafou et al., 2016). The authors conclude that more research on the mechanisms of mindfulness on PA, specifically self-regulation as a mechanism, could foster more knowledgeable intervention practices, and consequently improve mindfulness-based interventions efficacy.
Make-Believe Spelunking
Authors: Dunch Jonah
Published: May 2021

To what extent, and in what ways, is it possible for works of fiction to influence their readers’ ethical development? In this essay, I explore different answers to this descriptive question in philosophy and literary studies. I dub a view shared by Iris Murdoch and Martha Nussbaum as the attention account: that great works of fiction can influence their reader’s ethical development by compelling them to cultivate ethically charged attention. I then evaluate Joshua Landy’s criticism of this account and his alternative, which I dub the clarification account: that works of fiction can influence their reader’s ethical development by helping them clarify their core ethical commitments. I argue that neither the attention account nor the invitation account describes the one and only way in which works of fiction can influence their readers’ ethical development. I then ask a normative question: what ways in which works of fiction can influence our ethical development should we embrace? Drawing on Kendall Walton’s make-believe model of fictional experience, I develop an account of a third way in which works of fiction can influence their readers’ ethical development, which I call the invitation account: works of fiction can influence their readers’ ethical development by inviting them to unseat and positively revise their ethical commitments. I make the case for the invitation account by using it to analyze two contemporary novels, Rachel Cusk’s Outline and Marilynne Robinson’s Gilead. I argue that the process described by the invitation account—that is, the way of invitation—is one we should embrace.
Terahertz radiation may not alter rat basophilic leukemia cell membrane permeability to propidium iodide
Authors: Ayyalasomayajula Savita , Willows Steven , Hough Cameron , Hegmann Frank , Kulka Marianna
Published: May 2021

Terahertz radiation (THz) technology is fast-growing, with applications in sensing, security, monitoring and pharmaceutical industries. Since it is non-invasive, THz has been used as a diagnostic and therapeutic tool in medicine but its specific effects on biological systems is still largely under-studied. THz has been used to image tissues and cells mainly because it allows for identification of morphological features without the need for fluorescent or radioactive labels, but the potential effects of high intensities of THz radiation are currently not well understood.  One of the hypotheses that has been proposed for possible effects of THz on living cells, is that it disrupts the cell membrane and induces increased permeability. To test this hypothesis we exposed a rat basophilic leukemia cell line (RBL-2H3) to non-thermal intense THz radiation (duration, dose, etc) and observed the internalization of propidium iodide, a fluorescent intercalating agent that binds to DNA. We did not observe any changes in RBL-2H3 fluorescence following exposure to these intense THz pulses suggesting that exposure of RBL-2H3 to THz radiation may not increase their membrane permeability. These experiments were preliminary and further optimization and analysis is required before we can make definitive conclusions. However, our preliminary observations have set a baseline of RBL-2H3 internalization of propidium iodide, show that it is possible to expose RBL-2H3 cells to THz radiation using our configuration, and set the stage for future experiments.
Immunogenetic Epidemiology of Dementia and Parkinson’s Disease in 14 Continental European Countries: Shared Human Leukocyte Antigen (HLA) Profiles
Authors: James Lisa M. , Georgopoulos Apostolos P.
Published: May 2021

Human leukocyte antigen (HLA), which is critically involved in immune response to foreign antigens and in autoimmunity, has been implicated in dementia and Parkinson’s disease. Here we report on the correlations between the population frequencies of 127 HLA Class I and II alleles and the population prevalence of dementia and Parkinson’s disease in 14 Continental Western European countries, extending previous work1,2. We used these correlations to construct and compare HLA profiles for each disease3. We found that (a) the HLA profiles of the two diseases were significantly correlated across both HLA Class I and Class II alleles, (b) negative (“protective”) HLA-disease correlations did not differ significantly for either HLA class, but (c) positive (“susceptibility”) HLA-disease correlations were significantly higher in dementia than in Parkinson’s disease for both HLA classes of alleles. These findings indicate that (a) dementia and Parkinson’s disease share immunogenetic HLA-related mechanisms, (b) HLA-related protective mechanisms (presumably against pathogens) do not differ between the two diseases, but (c) HLA-related susceptibility mechanisms (presumably underlying autoimmunity) are significantly stronger in dementia than in Parkinson’s disease.

Published: May 2021

Objective: The FITT (Frequency, Intensity, Time, and Type) principle is an effective foundation in EP. However, the CORRECT components; C–Combination of interventions, O–Order of the Interventions, R–Repetitions, R–Rest period between sets and between sessions, E–Exercise at home, C–Cognitive domain, T–Total dose and re-evaluation plans, should be considered. The purpose of this paper was to describe the updated dynamic and evidence based FITT-CORRECT principle of EP and demonstrates its application using a case study. Results: Literatures, related to EP, clinical reasoning and clinical decision-making, were critically reviewed. Established evidence is summarized to describe an updated dynamic and evidence-based principle of EP. The gaps within the FITT and other related principles of EP are addressed. The FITT-CORRECT principle was introduced and an effective outcome of the updated principle was demonstrated using a case study. The FITT-CORRECT principle integrates many components that are missing in the FITT and other related EP principles. Based on the reported case study, the FITT-CORRECT principle of EP should optimize patients’ intervention outcomes. Physiotherapists can potentially improve their EP by utilizing the FITT-CORRECT in clinical practice.
Chronic fatigue syndrome and epigenetics: The case for hyperbaric oxygen therapy in biomarker identification
Authors: Rajit J Shah
Published: May 2021

Chronic fatigue syndrome (CFS) is a poorly-understood respiratory condition that affects millions of individuals. Hyperbaric oxygen therapy (HBOT) is a treatment option being considered to address CFS as it is suggested to combat fatigue and increase oxygenation. HBOT provides two opportunities in advancing research of CFS: it may provide data on symptom amelioration and be utilized in the search for a biomarker. By either identifying biomarkers before using HBOT to compare epigenomes of patients before and after treatment or using HBOT to find epigenetic discrepancies between patients with and without treatment, matching epigenetic regulation with symptom amelioration may significantly advance the understanding of the etiology and treatment mechanism for CFS. EPAS1/HIF-2α is a leading candidate for an epigenetic biomarker as it responds differentially to hypoxic and normoxic conditions, which degrades more slowly in hypoxic conditions. Epigenetic regulation of EPAS1/HIF-2α in such differential conditions may be explored in HBOT experiments. In addition to HBOT as a promising treatment option for CFS symptoms, it may aid the identification of biomarkers in CFS. Further research into both outcomes is strongly encouraged.

Importantly to study the coastal vegetation from Kekara Laut (Canavalia maritima Thou.) to observe the antibacterial agents towards Staphylococcus epidermidis. The purpose of this study to examine the variation concentration effect of an ethanol leaf extract from Canavalia maritima Thou. in inhibiting the growth of S. epiderimidis bacteria. The leaf of Canavalia maritima Thou. was prepared using a physicochemical method to obtain ethanol extract, then varied in several concentrations, namely 5% w/v; 10% w/v; 15% w/v; and 20% w/v. Based on these results, we obtain the ethanol leaf extract can inhibit the growth of S. epidermidis with a concentration of 15% w/v for 24 hours having an inhibition zone of 17.17 mm. The statistical analysis test was very significantly different from all antibacterial tests, the value of F count was 682.1 with F table (3.48), at the level of α = 0.05 (3.48) and α = 0.01 (5.99), which indicates that H0 is rejected, but using the Variance method in the Newman-Keuls range approach shows that each concentration has a good inhibitory ability. The use of Canavalia maritima Thou. leaf extract in low concentrations can significantly inhibit bacterial growth (bacteriostatic).

The study is devoted to defining the basic principles of formation of the style direction "unisex" as a design practice of fashion design; the formulation of generalized image-design characteristics of this style direction for the development of costume collections as a relevant fashion product for mass consumption. Methodology of research is based on a comprehensive approach to identifying image-design and artistic-compositional properties of costume collection development, in particular methods of socio-cultural analysis, historical and logical development, system-structural, comparative, compositional and stylistic analysis. At separate stages methods of morphological analysis and synthesis, sociological interrogation are applied. The origin of the "unisex" style direction, its features, the obligatory compositional elements in fashion design, the evolution of form, the main elements of products in the style of "unisex" are studied. The stylistic direction of "unisex" is characterized from the standpoint of assimilation of interactive development of men's and women's costume of the twentieth century. The systematization of figurative-design and constructive-compositional features of the main substrates of the style direction "unisex" in the modern market of fashionable clothes of general purpose is carried out. It is identified and characterized the artistic and compositional features of the collection of modern women's clothing in the stylistics of "unisex", taking into account modern materials. The general features of the collection models are systematized and the elements characteristic of the "unisex" style direction, which are the basis for designing the author's collection of women's clothing are structured. The author's collection of women's clothing, corresponding to the tendencies of the "unisex" style direction, has been designed. The scientific novelty of the study is to determine the image-design properties of the style direction "unisex" as a design practice in modern fashion design for mass consumption. The degree of aesthetics of the ideological content and gender aspects of the image-project of "unisex" phenomenon in the modern cultural and artistic space is determined. The main elements of the suit, which interactively interact with the design of men's and women's clothing as a fashion product, have been identified. The practical significance of the study of the main design characteristics of the application of the style direction of "unisex" in clothing design is determined by commercial potential, which allows fashion designers in the mass market segment and clothing brands to reduce production costs and further promotion: a single design, collection for men and women from the same materials, general advertising, etc.

The purposeof the study is to find the ways of the creation of the dynamic visual communications on bus stops. It will make the interaction of the message, a human and the environment harmonious. Methodology.The work is based on the system approach. It makes possible to consider dynamic visual communications as the integral area for the communication of a human and the environment. The results of the compositional and structural and functional analysis helped to make the generalization and systematization of the ways for the visual dynamic creation on bus stops. Results. In the study we consider the bus stop as the visual dynamic system with the intensive communicational processes, which are based on the integration of different forms of human sensitive experience and the urban environment. We proved that subject-visual, visual-sound, visual-tactile and digital visual communications substantiate the transformation of the information perception and deepen it. At the same time a human becomes a part of the communication. Bus stop turns into the experimental location and provides increased emotionality of the communicational processes due to the forming of the immersive context. The designer can afford to program the people’s behavior in the system of the visual dynamic communications. It allows creating opportunities for the stationary bus stops to adapt to the changing external living conditions. Scientific novelty.In the work we rethink the role of the visual communication in the bus stop structure and in the whole environment. The visual communication has an experimental nature. It proves that the communications in the environment are developing towards the increasing dynamics and immersion. Practical significance. The results of the study show the ways to increase the level of dynamics of the visual communications on bus stops. It will make the perception of the informational messages more effective and will make the urban environment more aesthetic. The features of the dynamical designing, which were found, can be used by specialists with the purpose of the designing of the modern environment. In addition, they can be used as the educational technology to form the system thinking of designers.

Purpose: to analyze the specifics of the Kyiv poster school of the Perestroika period. Methodology. Historical-comparative and art-scientific methods of analysis were used for the research. Results. The Perestroika period saw the final transformation of Ukrainian poster techniques and tools: from dogmatic system of Soviet school of visual arts to polystylistics of social, political, ecological and cultural posters at the time of fundamental social changes. Each of the major regional schools of the Ukrainian poster genre met the turning point of the era in accordance with its deeply rooted tradition or unconscious inertia. Appeal to the previously forbidden themes, repositioning of the theme of Ukrainianism in the poster, unexpected technical and artistic solutions, gravitating towards the smooth concepts of European poster movements – all this was presented and interpreted in terms of regional specificity. The attention of this study was focused on the Kyiv school. External and internal influences on the work of the Kyiv masters were analyzed. It was determined which themes were most often reflected in the posters and what were the stylistic changes. Scientific novelty. For the first time was covered the specifics of the Kyiv poster school and how it interacted with other poster schools in Ukraine. Practical significance. The study allows us to expand our knowledge about the activities and artistic features of the Kyiv school of posters during Perestroika. The findings can be used in further research of Ukrainian poster art.

Results.Stylistic features of satirical graphics by P. Kovzhun and E. Kozak in Lviv humorous magazines of 20–30s years of the XX century are determined. It is noted that the artistic style of these artists was influenced by Western European art trends, such as: modernism, expressionism, cubism, futurism. In their graphics, cartoonists use similar tools to achieve a greater effect – grotesque, allegory, zoomorphism. It is traced that each of these artists had his own individual style of satirical illustration, which was supported by national motives. The article draws parallels between German and Lviv satirical magazine graphics on the example of the magazine "Simplicissimus". It was found out that P. Kovzhun and E. Kozak, as leading artists of humorous publications, in addition to highly artistic illustrations, made high-quality graphic design for the magazines «Maski», «Zyz», «Komar». The artistic design of the covers and technical features of these publications are analyzed. Most satirical magazines had a symmetrical hierarchical composition of the title page with a limited polychrome palette. The logo-name on the cover of the magazine was harmoniously perceived together with the title illustration. The cover was made in color, usually in two colors, magazine covers were monochrome. The semantic load of visual satirical material in humorous editions of the interwar period is established. Scientific novelty. The satirical graphics with an emphasis on the national component of the leading illustrators P. Kovzhun and E. Kozak in Lviv humorous magazines of 20–30s years of the XX century is investigated and compared. The peculiarities of the design of the covers of popular Lviv satirical editions of the interwar twentieth century, such as «Maski», «Zyz», «Komar» are determined. Practical significance. Given data on satirical graphics in Lviv magazines of the 20–30s of the XX century and their artistic design will help in understanding the traditions of Ukrainian Galician satirical illustration and magazine design.

Kekasaran permukaan logam merupakan salah satu parameter yang dapat dijadikan acuan dalam penilaian mutu suatu logam. Nilai kekasaran permukaan suatu bahan logam dapat dilakukan dengan pendekatan matematik dan pengukuran. Pada penelitian ini, kajian mengenai kekasaran permukaan suatu logam dilakukan dengan menggunakan pengukuran langsung dan menggunakan analisis citra gambar. Adapun teknik pengukuran langsung dilakukan dengan  menggunakan Surftest  pada 20 titik (5 titik dari diagonal sisi kanan, 5 titik diagonal sisi kiri, 5 titik vertikal dan 5 titik horizontal) sedangkan analisis citra gambar dilakukan dengan menggunakan Image-J pada foto gambar permukaan besi. Berdasarkan metode penelitian yang telah dilakukan diperoleh kesimpulan yaitu semakin besar nilai grit abrasive paper yang digunakan pada permukaan besi, maka nilai kekasaran permukaan besi semakin kecil/semakin halus (nilai kekasaran permukaan cenderung menurun). Sedangkan hasil pengolahan citra gambar yang dilakukan dengan Image-J telah berhasil menunjukan surface plot permukaan sampel besi. Selain dari itu, gray value dari citra gambar yang dihasilkan mengalami fluktuasi seiring dengan semakin panjang/besarnya distance (pixels).
