Published: January 2022

This research examines how women voice their narratives through tattoos by studying the experiences of seven tattooed women. Using the in-depth interview method, this research presents the narratives of these tattooed women in relation to their tattoos. Such narratives seem to be strongly intertwined with their life stories. The body is a medium in which a person can place certain markers to achieve certain purposes. As Butler theorizes, what the body displays is not the real self, but only an appearance according to the assumed or chosen role. In addition, according to Cixous, tattooing can be considered as a form of writing and appropriation of expression for women who are far removed from traditional forms of language as a medium of communication which often serves patriarchic interests. As such, tattoos differ from symbols that outsiders can simply read. Women have their own process of choosing the permanent mode of writing on their bodies, and to understand that, we need to listen to the their narratives. When referring to the process and life story of women, tattoos also contain a narrative that is full of women's specific life experiences.

Published: January 2022

Background: Comparative features of embryos developed under in vitro and in vivo conditions are particularly important in designing embryo transfer procedures that fulfil embryo-recipient synchronization requirements. Objective: To determine the degree of asynchrony in rabbit embryo development between cultured and in vivo embryos. Methods: A total of 55 non-lactating multiparous female rabbits were used. Embryos were classified as 16-cells or early morulae at 48 hours post-coitum (hpc). Embryos were cultured during 30 or 32 h and embryo development was compared with in vivo embryos of 72 hpc. In vitro and in vivo embryos at 72 hpc were classified as early or compacted morulae. Bayesian statistics was used. Difference between in vivo and in vitro embryos and the actual probability of the difference between the in vivo and in vitro embryo higher than zero (P) was estimated. Results: The percentage of compacted morulae was higher in in vivo embryos than in in vitro embryos with +6 h of asynchrony (73.5 and 32.8%, P=1.00). But the percentage of compacted morulae was similar with +8 h asynchrony. Conclusions: In vitro embryos delay their development by + 8 hours compared to in vivo embryos.

Published: January 2022

Plug and Prognose bietet eine Diagnoselösung, die einem Plug-and-Play-Konzept so nahe kommt wie möglich. Das in diesem Beitrag behandelte Werkzeug ist dafür konzipiert, den Maschinenzustand zu beobachten und entstehende Störungen zu erkennen, ohne dass dafür eine Modellierung der Maschinenphysik, eine manuelle Parametrierung oder spezielle Maschinentestzyklen erforderlich sind. Die Software des Plug-and-Prognose-Prototyps kommuniziert mit der Maschinensteuerung, um die Betriebsbedingungen der Maschine - oder welche Funktion sie gerade ausführt - zu erfassen, und nimmt die Daten von der Maschine und ihren Sensoren auf. Anschließend wird die Datenanalyse anhand von in der Vergangenheit erfassten Daten für diese spezifischen Bedingungen angepasst. Um auch neue Betriebsbedingungen berücksichtigen zu können, erstellt Plug and Prognose automatisch neue Analysemodelle, wenn neue Bedingungen erkannt werden.

Published: January 2022

In einer idealen Umsetzung von Plug-and-produce würde eine noch unbekannte Anlagenkomponente während des laufenden Betriebs angekoppelt, automatisch erkannt und funktional in die Produktionsabläufe integriert; und das ohne manuellen Integrationsaufwand. Ein Ansatz dafür ist die Modellierung von Fähigkeiten in der Produktion. Sind die Fähigkeiten einer Anlagenkomponente bekannt, können diese mit den Anforderungen an einen Produktionsschritt abgeglichen und gezielt eingesetzt werden. In diesem Beitrag werden die Fähigkeiten technischer Anlagen über ihre Relationen zu Produkt, Prozess und Ressource definiert. Das Spannungsfeld des resultierenden Frameworks entsteht durch die Notwendigkeit, Fähigkeiten sehr allgemein zu definieren, um alle potentiellen Einsatzmöglichkeiten zu berücksichtigen. Im Gegensatz dazu müssen für die Automatisierung eines konkreten Produktionsschritts spezifische Details operationalisiert werden.

Published: January 2022

Ein in das Prozessleitsystem integrierter modellbasierter Prädiktivregler bietet hinsichtlich Verfügbarkeit, Benutzerfreundlichkeit, Wartung und Kosten dieselben Vorzüge wie ein konventioneller PID-Regler, hat aber das Potenzial zu deutlich höherer Regelgüte. Dies ermöglicht die Erschließung neuer Einsatzmöglichkeiten, bei denen ein separates full-blown MPC-Softwarepaket auf einem externen PC aus wirtschaftlichen Gründen nicht zu rechtfertigen ist. Der Beitrag fasst Aspekte zusammen, die bei der Auswahl von Einsatzmöglichkeiten für leitsystemintegrierte MPC-Lösungen relevant sind. Durch die Einbindung von MPC-Funktionen in wiederverwendbare Module auf der Ebene von Equipment Modules und auf der Ebene verfahrenstechnischer Units (Unit Templates) kann APC-Know-how einfach angewendet und der Engineering-Aufwand für MPC-Projekte reduziert werden.

Published: January 2022

Eine fundamentale Fragestellung der akademischen und industriellen Forschung des letzten Jahrzehnts war die Automatisierung der Automatisierung. Dabei wurden Konzepte mit dem Ziel einer teilautomatisierten Projektierung von Automatisierungslösungen entwickelt. Die Anwendbarkeit der Algorithmen ist abhängig vom Vorhandensein einer Beschreibung der Anlagentopologie in einem maschinenlesbaren Format. Da diese bei Altanlagen für Engineering-Aufgaben im Betrieb und bei der Modernisierung oft nicht zur Verfügung steht, müssen Alternativen gefunden werden, um die benötigte Information zu gewinnen. Im Beitrag wird eine Methode vorgestellt, die die benötigte Information aus der Mensch-Maschine-Schnittstelle erzeugt. Diese wird in einem Topologiemodell abgelegt, sodass sich die Algorithmen der Automatisierung der Automatisierung darauf anwenden lassen.

Published: January 2022

Ethernet-basierte Kommunikationssysteme unterliegen aufgrund ihrer Offenheit und Anbindung an das Internet einer besonderen Sicherheitsbetrachtung. Aus Sicht der IT sind vielfältige Erfahrungen vorhanden, um den Gefahren zu begegnen. Derzeit gelangen auch risikobehaftete Schwachstellen direkt an den Automatisierungsgeräten in den Blickpunkt, die sich entweder gezielt für Produktionsstörungen ausnutzen lassen oder die Stabilität des Netzwerks beeinflussen können. Um einen stabilen Netzwerkbetrieb zu gewährleisten, müssen Konzepte für Robustheitstests und für ganzheitliche Analysen, insbesondere für Profinet-basierte Produktionsnetzwerke, in Zusammenarbeit mit den Nutzerorganisationen erarbeitet werden. Für eine weiterführende Bewertung und Ableitung von notwendigen Maßnahmen ist dann die Formulierung von Anforderungen und Akzeptanzkriterien notwendig, die neben der Analyse von Lasttestszenarien in diesem Beitrag behandelt werden.

forma no como prefijo de negaci´ón
Authors: Esquivel Shaila
Published: January 2022

En este artículo se estudia el estatus morfológico de la forma no antepuesta a sustantivos, en donde parece estar funcionando como un prefijo; este uso no se ha estudiado a profundidad en la actualidad e, incluso, no es aceptado de manera general. Debido a lo anterior, se analizaron 196 contextos en los que aparece esta forma y a partir de ellos se planteó una descripción detallada de las condiciones de adjunción que presenta, así como todas las peculiaridades formales y funcionales de las palabras derivadas a partir de este elemento antepuesto. Este trabajo se aborda desde un punto de vista onomasiológico, a partir de un modelo dinámico que da cuenta de las nuevas palabras existentes, por tanto, este método se enfoca esencialmente en el estudio del proceso de nombrar, tomando como punto de partida el nivel conceptual que se orienta hacia la forma, camino opuesto al que se sigue en los más comunes estudios semasiológicos, cuyo análisis se centra en palabras ya existentes (Štekauer, 2005a, p. 207). Los resultados indican que la forma no se está integrando al paradigma de la negación morfológica en español, en donde es posible observar una especialización en sustantivos en comparación con el resto de los prefijos de negación.

Authors: Wujdi Arief , Kim Han Ju , Oh Chul Woong
Published: January 2022

The Indian mackerel, Rastrelliger kanagurta, is a commercially important resource across Indonesia's archipelagic waters. Despite its essential role in the fisheries industry, information regarding its population structures for management purposes is still limited. The present study investigates the variability of otolith shape as an efficient tool for stock discrimination. A total of 159 pairs of sagittal otolith were sampled at four localities along the southern Java-Bali coastal waters. Otolith outline was modeled by using Wavelet coefficients and was compared between localities using ANOVA-like permutation test, Canonical Analysis of Principal Coordinates (CAP), and classification test performed using linear discriminant analysis. The results showed significant differences in the shape of otolith between populations, reflected explicitly in the morphological feature of the excisura major. The differences in otolith shape were examined from all localities (ANOVA-like, p<0.001, and CAP p>0.05), except those otoliths between Palabuhanratu and Pacitan, thus, a mixed stock may occur in these two locations. These findings were also confirmed by the low classification success rate using LDA 44.26%. These results suggested that at least two distinct stocks potentially contributed to the fishery, impacting species management and conservation.

Authors: Zhou Jiang-Ming
Published: January 2022

It is important to develop a new convenient and environmentally-friendly technology of liming for sustainable rice production on acidic soil area. Thus, an experiment was conducted to evaluate the effect of application methods and rate of lime on soil properties and rice yield. The results showed that a similar ameliorating effect on agricultural acidic soil were found between massive quicklime and powered hydrated lime. Interestingly, optimized application rate of lime significantly increases rice yield, while over-liming leads to an adverse effect to the rice production. The changes of soil nutrients affected by liming rates were related to organic matter content and soil texture, with elevated mineralization of organic matter were found in organic and sandy soil. Conclusively, massive quicklime method has been found to be optimal for rice cultivation on acidic soil conditions with rates of 1500-2250 kg/ha for clay soil and 2250-3000 kg/ha for sandy soil, respectively.

Published: January 2022

Mitochondrial dysfunction is common in the brain with age. Prevention of mitochondrial dysfunction at an early age may protect the brain against neurodegeneration in later life. Tocotrienol-rich fraction (TRF) has been reported to be neuroprotective in old rats, but its effect remains unknown for middle-aged animals. This study aimed to determine the effect of TRF on activities of mitochondrial respiratory chain complexes in the hippocampus of middle-aged rats. Male Sprague Dawley rats were divided into 4 groups: young control (3 months old), adult control (12 months old), adult rats supplemented with palm kernel oil (PKO) as the vehicle, and adult rats supplemented with TRF by gavage at 200 mg/kg body weight/day for 3 months. At the end of the supplementation, activities of complex I, I+III, II, II+III, III, IV, and citrate synthase in the isolated mitochondria of the hippocampus were measured by spectrophotometry. Complex II activity was higher, while citrate synthase activity was lower in adult rats than in young rats. A decrease of citrate synthase activity suggests loss of mitochondrial mass and intactness in the hippocampus at middle age. Interestingly, PKO-treated adult rats had lower complex I and IV activities, but higher complex I+III activity than adult control rats. These findings indicate PKO modulated activities of the complexes. In TRF-treated adult rats, the complex I activity was higher, while the complex IV activity was lower than PKO-treated adult rats. TRF restored the complex I activity and may have the potential to reverse complex I deficiency.

Ethanol cannot be excreted and must be metabolized in the liver. Alcoholic liver disease is a blanket term for conditions related specifically to the liver and alcohol use. The study aimed to evaluate the metabolic, biochemical and histological effects of the oral supplementation with β-carotene on the liver of C57BL/6 mice exposed to ethanol consumption. Thirty male C57BL/6 mice (Mus musculus) were divided into six experimental groups: Control (C), Low-dose alcohol (LA), Moderate-dose alcohol (MA), β-carotene (B), Low-dose alcohol+β-carotene (LA+B) and Moderate-dose alcohol+β-carotene (MA+B) group. One-way ANOVA was used. The greatest intake of calories was noted in the LA (65.4 ± 12.5 kJ) and MA (68.6 ± 18.6 kJ) groups. The LA+B and MA+B groups shown an improvement in the HOMA-IR index (8.7 ± 2.4 and 6.7 ± 3.5, respectively), increased ADH levels (16.2 ± 1.6 and 18.9 ± 0.5 pmol/minmL-1, respectively) and decreased insulin levels (14.0 ± 3.3 and 10.6 ± 5.7 µUmL-1, respectively). It was also observed that oral supplementation with β-carotene improved the hepatic parenchyma in the LA+B group, showing normal-sized hepatocytes, whereas in the MA+B group it relieved the structural damage, revealing fewer lipid droplets than the MA group.

Published: January 2022

The developments in new communication technologies in recent years have made it possible to exist in political communication outside the election period. Social networks that emerged with Web 2.0 are important channels for providing and managing this communication. Social networks used by political actors such as Instagram, Facebook and Twitter are also of great importance in the continuity of political communication. Political parties already carry out this communication facility through the official accounts of the party headquarters. At the local level, the task of maintaining active communication with citizens falls on the provincial presidencies of political parties. Being visible in new communication environments, creating an agenda and ensuring the continuity of political communication, especially the young population, brings it with the advantage of winning. In this study, the use of social media by the Provincial Presidency of the Justice and Development Party, the Republican People’s Party, the Nationalist Movement Party and the IYI Party of the parties that entered the last local elections in Giresun Province, outside the election period, were evaluated using the content analysis method within the framework of the theory of gatekeeping, which was transformed by the emergence of digital technologies.
Frankfurt School’s Critical Theory and a Critique of Video Games as Popular Culture Products
Authors: SIĞIN Aykut
Published: January 2022

Frankfurt School’s critical theory provides a framework to study mass media. In Dialectic of Enlightenment, Adorno and Horkheimer, two of the most prominent theorists of the School, coined the term “culture industry” to discuss the state of the entertainment sector. However, the critical theorists of the Frankfurt School were either dead or they simply did not analyze the case of video games when the medium became an important agent both in social and economic terms. The main argument of this paper is that, as an inseparable part of the entertainment sector of today’s capitalist societies, video games are eligible for an analysis as products of the culture industry. It is argued in the study that the fantasy worlds of video games divert people’s attention away from the problems of capitalist societies. Further, the commodities are claimed to be getting increasingly standardized and are aimed at providing easy pleasures to consumers. Besides, a discussion of video games is carried out in accordance with the view that the video games of today seem to cater more to casual gamers than “serious” gamers, transpiring a dichotomy akin to that of high culture versus low culture.

Tüm dünyayı etkisi altına alarak, her geçen gün artan sayıda ölüme neden olan COVID-19 virüsü kaynaklı salgına karşı ciddi önlemler alınmış ve kısa sürede birçok farklı ülkede aşı çalışması başlatılmıştır. Geliştirilen aşıların onaylanması ve uygulanmaya başlanmasıyla birlikte, aşıların içeriği ve niteliğine dair üretildiği ülkenin imajıyla ilişkilendirilen çok sayıda görüş dijital ortamda dolaşım bulmuştur. Bu odak noktasından yola çıkan çalışma kapsamında, COVID-19 aşısının geliştirilmesiyle gerçekleştirilen bilimsel üretimin bir ülkenin imajıyla nasıl ilişkilendiğinin ve marka imajına nasıl bir katkıda bulunabileceğinin dijital ortamdaki kullanıcı yorumları analiz edilerek tespit edilmesi amaçlanmaktadır. Söz konusu amaç doğrultusunda, tek öğeli örnek olay incelemesi gerçekleştirilerek, Çin’de üretilen Sinovac aşısına Dünya Sağlık Örgütü’nün onay vermesini içeren haber kanallarının yayımladığı video haberlere gelen kullanıcı yorumları analiz edilmiştir. Çalışma sonucunda, aşıya ilişkin ülke orijiniyle ilişkilenen olumsuz kullanıcı yorumlarının (manipülasyon/ülke propagandası, aşı içeriğine güvenmeme) daha fazla olduğu; ancak olumlu yorumların (güçlü devlet imajı, gelişmiş sağlık teknolojisi, insan sağlığını önemseme) daha fazla etkileşim aldığı tespit edilmiştir.

Kophenag Okulu tarafından geliştirilen ‘güvenlikleştirme teorisi’ bir sorunun söylem yoluyla güvenlik sorunu olarak inşa edilmesi süreciyle ilgilenir. Bu araştırmada güvenlikleştirme teorisi ve bu teoriyi siber alana uyarlayan Hansen ve Nissenbaum’un yaklaşımından hareketle, popüler korku ve gerilim filmlerindeki siber güvenlikleştirme söylemi incelenmektedir. Bu bağlamda, farklı ülke sinemalarından internetin risklerine odaklanan 13 adet korku/gerilim filmi seçilmiştir. Bu filmlerde internet ve siber alandan kaynaklı bireysel ve toplumsal güvenlik tehditlerinin nasıl tanımlandığı, referans nesneleri, güvenlikleştirici aktörler gibi unsurların nasıl konumlandığı içerik analizi yöntemiyle incelenmiştir. Filmlerde internetin her türlü kontrol ve denetimden azade, tehlikeli ve kuralsız bir alan olarak sunulduğu, internet aracılığıyla tehdit unsurlarının kılık değiştirerek gündelik hayatın içerisine kadar sızabildiği ve kişisel mahremiyetin ihlal edildiği yolundaki argümanların öne çıktığı görülmektedir. Öte yandan gençler siber güvenlik söyleminin en temel referans nesnesi olarak sunulmakta ve siber alanın denetim altına alınması için devletin, uzmanların, bireylerin ve/veya ailenin vakit kaybetmeksizin harekete geçmesi gerektiği savunulmaktadır.

Korku, insanların herhangi bir tehlike unsuruna ya da düşüncesine yönelik verdiği duygusal bir tepkidir. Korkunun duygusal bir tepki dışında, insanların herhangi bir konu hakkında ikna edilmesi amacıyla kullanılması sonucunda ise karşımıza korku çekiciliği kavramı çıkmaktadır. Korku çekiciliğinde, “korku” öğesinin sunumuyla insanların istenilen şekilde hareket etmediği takdirde karşılaşabileceği olumsuz sonuçlar ön plana çıkarılmaktadır. Bu çalışmanın konusunu ise gazete haberlerinde Covid-19 pandemisinin korku çekiciliği bağlamında hangi dil ve söylem pratikleri kullanılarak inşa edildiğini ortaya koymak oluşturmaktadır. Çalışmada, Türkiye’de yayınlanmakta olan ve günlük tirajı yüksek olan Hürriyet, Milliyet, Posta, Sabah, Sözcü ve Türkiye gazetelerinin Covid-19 pandemisini manşete taşıyan haberlerinde korku çekiciliğini hangi dil ve söylem pratiklerini kullanarak haberleştirdiklerinin ortaya koyulması amaçlanmaktadır. Çalışmanın örneklemi, amaçlı örnekleme tekniğinden yararlanılarak belirlenmiştir. Bu bağlamda çalışmanın örneklemini Covid-19 pandemisinin ülkemizde ilk görüldüğü 11 Mart 2020 ile 1 Temmuz 2020 tarihleri arasında Hürriyet, Milliyet, Posta, Sabah, Sözcü ve Türkiye gazetelerinin pandemiyi manşete taşıyan haberleri oluşturmaktadır. Araştırmanın örneklemine dâhil edilen gazetelerden seçilen örnek haberler, korku çekiciliği bağlamında ele alınmıştır. Gazetelerin pandemiye yönelik bakış açıları Teun van Dijk’ın sistematikleştirdiği söylem analizi yöntemi ile çözümlenmiştir. Çalışma sonucunda, gazete haberlerinde Covid-19 pandemisi ile ilgili yaşanan gelişmelerin korku çekiciliği bağlamında ön plana çıkarıldığı ve bu doğrultuda dil ve söylem pratiklerinin tercih edildiği görülmüştür.
Siyasal Mit İnşasında Görsel Retorik Ya Da Kötülüğün Sıradanlığı
Authors: SAF Hacı Hasan
Published: January 2022

İkna edici iletişimde bir enstrüman olarak kullanılan retorik, çeşitli tekniklerle inandırıcılığı artırma amacıyla araçsallaştırılmaktadır. Bu araçsallaştırma, sanattan edebiyata, iletişimden tüketime kadar birçok alanda görülmektedir. Son yıllarda yeni iletişim teknolojileri ile kolaylaşan görsel üretme pratikleri, retoriğe de yansımış ve görsel retorik örneklerinin arttığı görülmüştür. Hemen her konuda üretilen görseller siyaset ve siyasal iletişimde kullanılan retoriğe de yansımıştır. Siyasal mit bunlardan yalnızca biridir. Siyasal tutum ve davranışı değiştirmek için yaratılan siyasal mitlerin bir toplumu bir arada tutma misyonu edindiği de görülmüştür. Böyle bir durumda görsel retorik, siyasal mit inşasındaki en önemli etmenlerden biri olmuştur. Amacı siyasal mit inşasında görsel retoriği incelemek olan çalışmada Hollandalı ırkçı siyasetçi Geert Wilders’in Instagram hesabından 2021 yılında paylaştığı görseller çözümlenmiştir. Göstergebilimsel analiz yönteminin kullanıldığı çözümlemede kötülük kavramın en sık karşılaşılan suretleri olan nefret söylemi ve ötekileştirme ile sınırlandırılmıştır. Analiz sonucunda nefret söylemi ve ötekileştirme gibi unsurların varlığı görülmüştür. Bu durum siyasal mit inşası gibi bir durumda bile görsel retorikte kullanılan unsurlarda kötülüğün sıradanlığını gözler önüne sermiştir.
Kamu Diplomasisi ve Dijital İletişim
Authors: BUDAK Muhammet Musa
Published: January 2022

Development in communication technologies and digitalization have deeply affected the norms, goals and working procedures of public diplomacy actors and institutions. This article discusses digitalization of public diplomacy and communication with two different dimensions. The first part is a functional dimension that focuses on the use of digital communication tools in public diplomacy activities. Effects of digital communication platforms on the working procedures and activities of public diplomacy institutions and the use of digital technologies in the evaluation of public diplomacy activities will be discussed. In the second part, how the values and norms of the digital society affect the practice of public diplomacy and the value perceptions of its practitioners will be analyzed with a normative approach.
Digitalization of public diplomacy processes cannot be understood without characterizing the digital society that emerged with developments in communication technologies. Digitalization in public diplomacy is an ongoing process where every country is at different levels. Although digitalization has caused radical changes from the language of public diplomacy to the use of social media in policy making, it has not been able to prevent the ongoing discussions in terms of values. As a requirement of digital society, structures of public diplomacy institutions should be flexible and may use digital technologies in innovative ways. Their response to innovation may not be immediate, but over time they are expected to learn to balance the possibilities of digital technologies, the demands of the digital society and their own goals.
Dijital Oyunlarda İhlal Biçimleri
Authors: DEMİRBAŞ Yavuz
Published: January 2022

Dijital oyunlar çağımızın en popüler iletişim ortamlarından biri haline gelmiş durumdadır. Genelde oyunlar ve özelde dijital oyunlar sıklıkla belli normları takip eden nitelikleriyle değerlendirilmektedir, ancak tarih boyunca oyunlar ihlallerin de alanı olmuştur. İhlal belirli bir sınırın, limitin geçilmesi, bir kuralın çiğnenmesi anlamına gelmektedir. Bu çalışmada oyunlardaki ve oyunlarla ilgili ihlal biçimleri incelenmektedir. Oyun ve gerçek yaşam ayrımı ihlale konu ilk sınırdır, ancak oyunlarla ilgili tek sınır bu değildir. Oyunların kuralları veya bir bütün olarak oyun alanı da ihlale konu olabilir. Oyunlardaki temsiller üzerinden toplumsal kurallar, yasaklar ve tabularla oynamak bazı oyunların esas öğesidir. Bu çalışma iletişim bilimleri ile kesişen dijital oyun çalışmalarının ve oyun biçimcilik olarak da anılan ludolojinin yöntemlerini kullanarak ihlal biçimleri ve örneklerini ele almaktadır. İhlal biçimlerini anlamlandırabilmek için öncelikle oyunların ihlale imkân veren nitelikleri ve oyun tanımları üzerinde durulmuştur. İhlal biçimleri belirlendikten sonra ihlal sınıflamaları ele alınmış ve var olan çalışmalarda eksik bırakılan bazı nitelikleri içerecek şekilde yeni bir sınıflama önerilmiştir.
