El objetivo del estudio fue determinar el efecto de tres curvas de congelación sobre la viabilidad pos-descongelación de espermatozoides colectados del conducto deferente de llamas. Se utilizaron seis llamas machos con desviación quirúrgica de los conductos deferentes. Las muestras de los seis machos se mezclaron para su procesamiento (pools) y se diluyeron con Tris-yema de huevo. Se procedió al enfriamiento hasta los 5 °C donde se completó la dilución (dilutor con glicerol) y se mantuvo por media hora (fase de equilibrio). Las muestras en pajillas de 0.25 ml fueron sometidas a congelamiento utilizando una tasa de descenso de temperatura de -20°C/min hasta llegar a -80°C (TI), a -100 °C (TII) y a -120 °C (TIII) en 4, 5 y 6 minutos, respectivamente, para finalmente almacenarlas en nitrógeno líquido. Las muestras fueron colectadas durante tres meses (n=19 pooles). Se determinó la motilidad total (motilidad progresiva, circular, oscilatoria), viabilidad y funcionalidad de membrana luego de la colecta, en la fase de equilibrio y al descongelamiento. Se observó una disminución significativa (p˂0.05) en todas las características espermáticas evaluadas en las muestras equilibradas respecto a las muestras luego de la colecta. Se obtuvo una correlación alta positiva entre viabilidad y motilidad total (r2=0.78) y en fase de equilibrio entre funcionalidad de membrana y motilidad total (r2=0.881) En las muestras descongeladas, la motilidad total y viabilidad fueron significativamente mayores en las muestras congeladas con la curva de congelamiento TIII respecto al TI (p=0.041 y p=0.003, respectivamente). No se observaron diferencias significativas en la funcionalidad de membrana entre las tres curvas de congelamiento (p˃0.27). En conclusión, la curva de descenso de la temperatura hasta los -120 °C utilizando una tasa de -20 °C/min sería la más adecuada para criopreservar espermatozoides de llama obtenidos a partir de la desviación de los conductos deferentes.

El estudio tuvo como objetivo determinar la prevalencia de helmintos hepáticos zoonóticos y su caracterización histopatológica en roedores (Rattus spp.) procedentes de un zoológico, granjas porcinas y mercados de abastos en Lima, Perú. Se registraron los parámetros morfométricos de cada roedor para determinar la edad e identificar las especies computándose un total de 267 animales. El manejo y la metodología de captura se realizó según los estándares de bioseguridad establecidos por el Centro de Enfermedades Infecciosas y Prevención de Atlanta. Los hígados fueron evaluados macroscópicamente en busca de lesiones. Para la confirmación diagnóstica por histopatología se tomó muestras del lóbulo lateral derecho de todos los hígados junto con otras áreas que evidenciaron daño en búsqueda de lesiones tisulares y respuesta inflamatoria relacionadas con la presencia de los parásitos. El análisis patológico determinó una prevalencia de 3.74% de Cysticercus fasciolaris en Rattus spp. no hallándose Capillaria hepatica. El análisis estadístico no evidenció asociación estadísticamente significativa entre las variables de estudio con C. fasciolaris (p>0.05). El diagnóstico histopatológico más común fue una moderada a severa colangiohepatitis eosinofílica granulomatosa asociada a C. fasciolaris. Los resultados indican que las ratas pueden ser fuentes de infecciones por C. fasciolaris en diversos entornos medioambientales, por tanto, permiten comprender el riesgo sanitario de las zoonosis que transmiten y su manejo.
On the non-closure under convolution for strong subexponential distributions
Authors: Konstantinides Dimitrios , Leipus Remigijus , Šiaulys Jonas
Published: December 2022

In this paper, we consider the convolution closure problem for the class of strong subexponential distributions, denoted as S*. First, we show that, if F, G ∈ L, then inclusions of F*G, FG, and pF + (1 – p)G for all (some) p ∈ (0; 1) into the class S* are equivalent. Then, using examples constructed by Klüppelberg and Villasenor [The full solution of the convolution closure problem for convolution-equivalent distributions, J. Math. Anal. Appl., 41:79–92, 1991], we show that S* is not closed under convolution.

Zoological museums and mammal collections in Kyiv for the last two centuries: history, values, and prospects
Authors:   National Museum of Natural History, NAS of Ukraine (Kyiv, Ukraine), Zagorodniuk Igor
Published: December 2022

The history of formation, development, and transformations of mammal collections in Kyiv in the 19th–21st centuries is considered. A description of the history of formation of key natural history museums and the pres-ence in them of scientific collections of mammals are presented. Descriptions are given by periods and institu-tions, including old museums that has existed since the late 20th century. Among the descriptions are historical collections that has existed since the first half of the 20th century (including museums of Kyiv Polytechnic In-stitute, Ukrainian Scientific Society, Institute of History of Material Culture, and Pedagogical Museum) and collections that disappeared during World War II (museums of Kyiv State University and Ukrainian Agricul-tural Academy). The second part of the review is about modern museum collections that exist in such institu-tions as Kyiv National University (KNU), National Museum of Natural History (NMNH), and two museums (anatomical and forest birds and mammals) at the National University of Life and Environmental Sciences (NUBiP), as well as collections at the Institute of Geological Sciences (IGS) and the Institute of Zoology (IZAN) of the NAS of Ukraine. Additionally, brief information about famous museologists (taxidermists, researchers, collectors, and heads) as well as information about catalogues and other reviews of mammal collections are given. The details of migration of the collections are analysed, in particular as a result of social and military conflicts, due to the closure, merger, and status change of institutions. Despite the great risks of losing the col-lections, they had been saved repeatedly thanks to the care of museum workers and scientists. The NMNH is the leader by the volume of collections, among which the collections originally deposited in KNU, IZAN, and NUBiP occupy a special place. The prospects of further existence of the collections in their current state and the importance of supplementing the traditional criteria of their value with new ones that will meet the new tasks of faunal, morphological, biogeographical, and phylogenetic research are considered. Materials suitable for 3D morphological and genetic analyses are important among such new challenges.

Objective

To evaluate the impact of a motion-correction (MC) algorithm, applicable post-hoc and not dependent on extended padding, on the image quality and interpretability of coronary computed tomography angiography (CCTA).

Methods

Ninety consecutive patients undergoing CCTA on a latest-generation 256-slice CT device were prospectively included. CCTA was performed with prospective electrocardiogram-triggering and the shortest possible acquisition window (without padding) at 75% of the R-R-interval. All datasets were reconstructed without and with MC of the coronaries. The latter exploits the minimal padding inherent in cardiac CT scans with this device due to data acquisition also during the short time interval needed for the tube to reach target currents and voltage (“free” multiphase). Two blinded readers independently assessed image quality on a 4-point Likert scale for all segments.

Results

A total of 1,030 coronary segments were evaluated. Application of MC both with automatic and manual coronary centerline tracking resulted in a significant improvement in image quality as compared to the standard reconstruction without MC (mean Likert score 3.67 [3.50;3.81] vs 3.58 [3.40;3.73], P = 0.005, and 3.7 [3.55;3.82] vs 3.58 [3.40;3.73], P < 0.001, respectively). Furthermore, MC significantly reduced the proportion of non-evaluable segments and patients with at least one non-evaluable coronary segment from 2% to as low as 0.3%, and from 14% to as low as 3%. Reduction of motion artifacts was predominantly observed in the right coronary artery.

Conclusions

A post-hoc device-specific MC algorithm improves image quality and interpretability of prospectively electrocardiogram-triggered CCTA and reduces the proportion of non-evaluable scans without any additional radiation dose exposure.
Towards Continual Reinforcement Learning: A Review and Perspectives
Authors: Khetarpal Khimya , Riemer Matthew , Rish Irina , Precup Doina
Published: December 2022

In this article, we aim to provide a literature review of different formulations and approaches to continual reinforcement learning (RL), also known as lifelong or non-stationary RL. We begin by discussing our perspective on why RL is a natural fit for studying continual learning. We then provide a taxonomy of different continual RL formulations by mathematically characterizing two key properties of non-stationarity, namely, the scope and driver non-stationarity. This offers a unified view of various formulations. Next, we review and present a taxonomy of continual RL approaches. We go on to discuss evaluation of continual RL agents, providing an overview of benchmarks used in the literature and important metrics for understanding agent performance. Finally, we highlight open problems and challenges in bridging the gap between the current state of continual RL and findings in neuroscience. While still in its early days, the study of continual RL has the promise to develop better incremental reinforcement learners that can function in increasingly realistic applications where non-stationarity plays a vital role. These include applications such as those in the fields of healthcare, education, logistics, and robotics.
A call for action: Air Pollution, a serious health and economic hazard suffocating Africa
Authors: Isaxon Christina , Abera Asmamaw , Asfaw Araya , Bililign Solomon , Eriksson Axel , Malmqvist Ebba , Teji Roba Kedir
Published: December 2022

Air pollution research has been conducted in Europe and North America as well as in Asia and South America for decades. Until recently, global inventories of pollutants from North America Europe and Asia have been used for air quality and climate change modelling in Africa (Bond et al., 2004, Streets et al., 2004, Bond et al., 2007, Klimont et al., 2009, Klimont et al., 2013, Lamarque et al., 2010). Research in air pollution has, however, been lagging far behind in Africa, despite the increasing death toll and the economic impact associated with air pollution in these nations. The health impact of air pollution in African cities has only been sparsely studied: a review from 2018 (Coker and Kizito, 2018) found only 3 studies outside South Africa. Earlier last year, a study showed that air pollution was responsible for 1.1 million deaths across Africa in 2019, with household air pollution—driven largely by solid biofuel used in indoor cook stoves—accounting for 697 000 fatalities (64%), while increased outdoor air pollution claimed 394 000 lives (36%) (Fisher et al., 2021).

Published: December 2022

The purpose of the study was to develop and experimentally justify the effectiveness of the algorithm for building individual training programs for highly qualified multi-sport athletes at the stage of direct preparation for the main competitions of the winter season.
Materials and methods. Five highly qualified multi-sport athletes, whose sports qualification is the Master of Sports of Ukraine, took part in the pedagogical experiment. The mean age of the participants was (M±SD) 25.2±1.79 years. The main goal of the formative stage of the experiment (2020-2021) was to develop programs for the structural units of the training process (training classes, microcycles, mesocycles, and the stage of direct preparation for the main competitions) based on the developed algorithm for building individual programs. We have developed six consecutive steps for the purpose of achieving full preparation of athletes for major competitions.
Results. The implementation of an individual program at the stage of direct preparation for winter season competitions is effective and enables qualified multi-sport athletes to reach the peak of their sports form during participation in the competitions of the Ukrainian indoor heptathlon championship. This is evidenced by the achieved statistically significant differences (р<0.05) in all indicators of physical and functional fitness compared to the ascertainment stage of the experiment. The increase in indicators was 2.8–4.4 % in the running tests, 4.0–4.2 % in the tests reflecting speed and strength abilities, 6.6 % in the strength control exercise. We note a statistically significant (p<0.05) positive increase during the formative stage in the indicators of physical performance of multi-sport athletes within the range of 5.8–6.0 % and in the indicators of aerobic productivity within the range of 4.4–4.5 %.
Conclusions. The use of the algorithm for building an individual program of preparation for competitions of highly qualified multi-sport athletes orients the coach and athlete towards achieving the desired sports result in the shortest way with economical and rational use of training equipment at the most difficult and responsible stage of direct preparation for the main competitions. Compliance with the stated provisions of the algorithm made it possible to rationally plan and choose the best option for building the training process.
The Significance of Students’ Physical Activity for Their Engagement in Learning Activities During the Covid-19 Pandemic
Authors: Kemeryte-Ivanauskiene Egle , Brandisauskiene Agne , Cesnaviciene Jurate , Daugirdiene Ausra
Published: December 2022

Study purpose. This study aims to clarify the extent to which students’ physical activity is significant for their engagement in the learning process.
Materials and methods. The study sample was composed of 202 7th-10th grade students. The data collection was performed in May 2021. The research participants completed the anonymous questionnaire on an online platform. The standardized Physical Activity Questionnaire for Adolescents and the standardized Student Engagement Scale were used to assess levels of physical activity and affective and behavioural engagement.
Results. The research findings showed that students’ physical activity depended on the time they participated in physical activities. The highest level of physical activity was during physical education classes. A statistically significant difference was determined in the boys’ and girls’ affective and behavioural engagement. The mean for the girls was higher than the mean for the boys. A statistically significant difference in the behavioural engagement of the 9th and 10th grade students was also found: 9th grade students were more engaged than 10th grade students. The multiple linear regression analysis demonstrated that gender (β = 0.332, p < 0.0001) and physical activity (β = 0.323, p < 0.0001) as predictors had a significant moderate effect on behavioural engagement.
Conclusions. The research findings reveal that although the students’ physical activity was low during the COVID-19 pandemic period, this phenomenon (physical activity) still remains a predictor, which has a significant moderate effect on behavioural engagement. It was also determined that during the pandemic, the highest physical activity level of students depended mostly on obligatory physical education lessons. Thus, bearing in mind that physical education lessons were the main physical activity-enhancing measures, we would like to emphasise the importance of these lessons and their proper organisation.

Published: December 2022

Study purpose. Physical education, sports and health for elementary school students are oriented to learning locomotor movements, so learning these skills requires fun activities, such as games. This research aims to develop a basic locomotor learning model based on a small game competition for elementary school students.

Materials and methods. This study used a research and development approach using ADDIE model. This research was carried out in three elementary schools, namely: Elementary school 22 Gelumbang, Elementary school 11 Gelumbang and Elementary school 2 Lembak. Data were collected using observation, interview, questionnaire, and test. The questionnaire instrument used in this study was the Guttman scale questionnaire because of using the Guttman scale. Expert judgments were used to analyze the product.

Results. The model can be applied in all elementary schools in the territory of Indonesia because product development has referred to competencies and learning outcomes in the 2013 curriculum. There are four types of games that have been developed for learning locomotor skills, namely 1) jump rope game, 2) watch out for crocodiles, 3) continuous running game, and 4) box jump game. Each game has different locomotor skill movements, including walk, run, slide, leap, gallop, skip, jump, and hop. Based on the effectiveness aspect, the results of the product trial show that the ‘wary crocodile game’ is a game that is in great demand and favored by students.

Conclusions. The locomotor skills learning model for elementary school students based on small game competitions has been feasible and effective for use in sports and health physical education classes. This model can also be applied in all elementary schools in the territory of Indonesia because product development has referred to competencies and learning outcomes in the 2013 curriculum.
Relation Between Physical Abilities and Fundamental Motor Skills in Preschoolers
Authors: Milenković Dejan
Published: December 2022

The aim of this study was to determine the interconnection between physical abilities and fundamental motor skills in preschool children. The aim was also to determine the differences in the observed variables in relation to gender.

Materials and methods. The testing successfully included 52 preschool children, 30 boys and 22 girls. Five tests of physical ability (modified agility "T" (MAT) test, broad jump test, standing balance test, squat test and sit up test) were used, and fundamental motor skills were assessed with the Test of Gross Motor Development, 3rd edition (TGMD-3). One-way ANOVA was used to determine the effects of gender on results in physical abilities and fundamental motor skills. The Pearson product-moment correlation coefficient was used to determine the relation between physical abilities and fundamental motor skills.

The results of this work indicated, in most cases, a moderate and significant correlation of fundamental motor skills and parameters of physical abilities both in the total sample and also individually in boys and girls (p≤0.05). A significant difference in almost all variables of physical abilities and fundamental motor skills was noted in favor of boys (p≤0.05 and p≤0.01), except for the Standing balance test which indicated that there were not considerable differences between the sexes (p > 0.05).

Conclusions. So it can be concluded that the information obtained can lead physical education educators to better understanding of the relations between motor status variables, which further enables them to work effectively with children who will, by virtue of a proper physical development and education, become and remain physically active throughout their life.

Authors: Zima Dmytro , Ivashchenko Olha
Published: December 2022

The study's purpose was to determine the specific features of the effect of the number of repetitions and rest intervals on the effectiveness of the standing long jump training program for 14-year-old girls.

Materials and methods. The study participants were 40 girls aged 14. The study participants were informed about all the features of the experiment and gave their consent to participate therein. The study used methods of analysis of scientific and methodological literature, observation, pedagogical experiment, and methods of mathematical statistics. The pedagogical experiment was designed as a full factorial experiment with a 2к factorial design. The effect of the number of repetitions (6 to 12 times) and the rest interval (60 to 120 s) on the effectiveness of the standing long jump training program for 14-year-old girls was investigated. Discriminant analysis was used for data analysis.

Results. The analysis of the experimental data showed that the modes of alternating physical exercise performance and rest intervals have a statistically significant effect on the formation of the motor skill of standing long jump in 14-year-old girls (p < 0.001). It is after the third exercise performance mode that the girls spent the smallest total number of repetitions required for the formation of the standing long jump skill. Thus, the 1st, 4th and 6th series of training tasks are learned faster after the third exercise performance mode, the 3rd series of training tasks is learned faster after the second exercise performance mode, and the 2nd and 5th series of training tasks are learned faster after the fourth exercise performance mode (p<0.001).

Conclusions. It was established that the mode of alternating exercises in 3 sets of 2 repetitions with a rest interval of 120 s is classified as the most rational. A specific feature of the formation of the motor skill is that each of the modes can be considered as a priority for one or another motor task. In the investigation of the learning process, discriminant analysis makes it possible to classify work modes and determine the relationship between the motor tasks within the training program.
Non-Cognitive Skills of NEET Youth in Russia
Authors: Zudina Anna
Published: December 2022

The study of non-cognitive skills of NEET youth — e.g., those who are out of employment, education or training — presents an important development in the research framework of the factors of being NEET. The very presence and level of various non-cognitive skills since childhood affect the process of accumulation of human capital, future productivity, wage level, occupational choice, duration and quality of job search. The empirical basis of the study was provided by the data of the Russia Longitudinal Monitoring Survey Higher School of Economics (RLMSHSE) for 2016-2017. The choice of this period is determined by the special module of questions about non-cognitive skills according to the Big Five classification, included in RLMS-HSE questionnaire in 2016. They provided the empirical assessment of five personality traits of respondents, which are most often analysed in modern research literature on non-cognitive skills. Different types of NEET youth, students and employed young people were compared with respect to their level of these non-cognitive skills. Measures of non-cognitive skills have also been used as explanatory variables in multinomial logit models of ‘choice’ of particular labour market status type among young people, as well as in dynamic multinomial logit models, describing their transition from education to one of the NEET types. Research results revealed differences in non-cognitive characteristics between groups of young people occupying different positions in the field of education and employment. The obtained results indicate that non-cognitive framework of analysis of success of young people in education and work confirms its relevance on Russian data.
From Passing the Exam to Self-Actualisation: Different Ways of Conceptualising Success among Adult Students in Online Higher Education
Authors: Rotar Olga
Published: December 2022

Knowledge about adult students’ perspectives on success is scarce, with a slim history of research in online higher education. To fill this gap, this article reports on the results of a phenomenographic investigation of alternative perspectives on success among adult students from two online postgraduate programmes. The study uncovered that adults’ perspectives fell into five categories: obtaining satisfactory exam results and getting a degree, understanding, improvement in their professional practice, the opportunity to open doors, and self-actualisation. The study provides the research community and educators with information on what is missing from the full definition of the concept of success from the perspective of adult students in online higher education.
Learner Corpus in German as a Data Source for Education and Science
Authors: Kotiurova Irina , Shchegoleva Liudmila
Published: December 2022

One example of the digitalization of education is the creation of a linguistic learner corpus of student papers in a foreign language at an educational institution in order to use this corpus for research, teaching and learner analytics. This paper describes the experience of creating such linguistic learner corpus at Petrozavodsk State University. Petrozavodsk Annotated Corpus of Texts (PACT) was founded in 2020, but even 2 years of its development have already shown a wide field for implementing this experience in the work of a university. The article provides a general description of the learner corpus PACT and gives examples of its use – being implemented and planned to be implemented. The key research question is what opportunities for training and professional development of future foreign language teachers offers and what potential for educational data mining and management of the educational process the learner corpus in a foreign language has. Answering this basic question, the authors refer to the experience of another corpus of student texts — REALEC, the English annotated learner corpus, which is the prototype of the original PACT corpus. The authors conclude that the corpus of student texts in a foreign language, as an example of big data collected in a university, has great potential in several directions: for research purposes for specialists in linguistics, linguodidactics, psycholinguistics, information technology and artificial intelligence; for educational purposes directly applied in the foreign language classes, for students research work and as a resource for individual tasks automatic generator; for educational data mining.

For years, geotechnical engineers have been concerned about expansive soils. Expansive soils are characterized by large volumetric changes related to variations in moisture content. Variations in soil water content may take place naturally during seasonal changes or maybe manmade caused by dewatering activities. The quantity of shrinkage and swell is influenced by numerous parameters, including the quantity of minerals clay in the soil, moisture content, dry density, and climate change. In most countries, numerous structures, including pavements and buildings, are damaged as a result of this shrinkage/swelling. Several ground improvement techniques are available for stabilizing expansive soil to modify its engineering performance. These methods include soil replacement, mixing with chemical additives, and soil reinforcement. The present study expressions the effect of nano-lime (i.e., 0.1, 0.3, 0.5, 0.7, 1.0, 2.0 and 3.0%), and lime (1, 3, 5, 8, and 10%), as chemical additive to improve clayey soil (i.e., illite and kaolinite). The effect of nano-lime and lime were investigated using Atterberg’s limits tests. The Atterberg limits were screening significant changes in the proportion of additional nano-lime and lime. The results show that less amount of nano-lime (1% and 2% for illite and kaolinite respectively) decreased the plastic limit, while for lime it was reported 8% for illite and 5% for kaolinite respectively. In conclusion, less quantity of nano-lime (1-2%) is able to improve soil parameters.

An emergency route is a route designed for human use to save themselves from dangerous situations. However, if it is considered trivial, this has unknowingly led to an increase in accidents. The provision of emergency routes on a community scale in indoor areas in terms of time is rarely discussed in emergency evacuation studies. This study aims to investigate the emergency route in the building due to the environmental factors of the closed area and the arrangement of office equipment. The method of this study is divided into two sub-sections, namely data preparation and data analysis process. Demographic data and physical interactions were used as the selection of walking speed criteria while the use of geometric data to see the actual plan route position of the building. 3D building models are built through Revit software and then converted to industry foundation classes format (.IFC) and then to multipatch shapefile (.shp) to be integrated into ArcGIS software. This is intended for the use of the data analysis process that is to build a geometric network model (GNM). GNM is designed to determine the safest and shortest routes by taking into account a variety of obstacles based on the scenario conditions. The findings shows that the evacuation time is influenced by the speed and distance of the route. 80% of the safest route selection takes a long time compared to the shortest route, while 20% is the same distance and time for the shortest and safest route because route selection is the same. The findings able to be used as a reference and guideline to determine the selection of emergency routes, especially in complex buildings.

Heart failure (HF) is a complex syndrome with high mortality and hospitalization rates. Conventional care in patients with HF is usually based on clinical history and physical examination. Natriuretic peptides (NPs), B-type NP (BNP) and N-terminal proBNP, are the gold-standard biomarkers in HF. They are recommended for diagnosing HF, when the physician is uncertain of the diagnosis, and for estimating the prognosis. NPs also guide therapy in HF, as serial NP measurements inform medication adjustments to achieve targets independently of symptoms. In this regard, the data are conflicting. In patients with HF and reduced left ventricular ejection fraction (HFrEF) there is a suggestion that NP-guided therapy is helpful. The studies STARS-BNP and PROTECT demonstrated a reduction in cardiac events with NP-guided therapy. Additionally, mortality in patients aged <75 years reduced in the BATTLESCARRED and TIME-CHF studies, and in a meta-analysis. On the contrary, no differences were observed in the studies PRIMA and GUIDE-IT. In HF with preserved ejection fraction (HFpEF) and in the acute setting, no differences were detected with NP-guided therapy compared with conventional care. In patients at risk of developing HF, NP can be useful to guide therapy and prevent HF. In summary, NP-guided therapy seems to be useful in patients with HFrEF, especially in those aged <75 years, but has no use in HFpEF or in acute HF.

Hepatocellular carcinoma is the most common primary liver tumor. Hepatocellular carcinoma usually makes metastasis to bones. Prognosis of bone metastasis of hepatocellular carcinoma is becoming better with early diagnosis and improvements in treatment modalities. As survival increases, bone metastasis is faced more. However, humerus metastasis is very rare. Bone metastasis may result in symptoms and pathologic fractures. Hepatocellular carcinoma metastasis of bone worsens patients’ quality of life. Early diagnosis and proper treatment are very important. Herein we report a rare case with humerus metastasis of hepatocellular carcinoma which is treated with resection and endoprosthesis.

Reklam sembolik bir mesajdır ve göstergebilim klasik bir yöntem olarak, reklamcılık alanında özellikle de mesajları oluşturma ve analiz süreçlerinde yaygın olarak kullanılmaktadır. Reklamların etkili olabilmesi için stratejiler geliştirilirken işaretler, sembolizm ve tüketici davranışı gibi konulardan faydalanılmaktadır. Reklam göstergebilimi, pazardaki iletişim ve anlamı incelemek için en zengin kaynaklardan biridir. Göstergebilim işletmelere iletişim açısından da fırsatlar sunmaktadır. Çalışmada Lipton’un #konuşalımartık reklam kampanyasına ait reklam afişleri örnek olarak seçilmiştir. Bu kampanyada ideolojik açıdan aktarılmak istenen mesajın sembolik göndermelerle nasıl aktarıldığı “iletişimsel bir bakış açısı” ile incelenmiştir. Göstergebilimde öncü olan Ferdinand de Saussure’nin teorileri temel alınarak her bir afiş için analiz yapılmıştır. Yapılan analiz neticesinde belirli simgesel mesajların tutarlı bir şekilde tekrarlandığı, bu sayede hedef kitleye mesajın ideolojik olarak benimsetilmesinin kolaylaştığı görülmüştür. Kültürel simgelerin ve sembolik göstergelerin kendinden beklenen anlam aktarma işlevini başarı ile yerine getirdiği, ayrıca metin ve görsel unsurların birbirini desteklerken aynı zamanda anlamı da pekiştirdiği sonucuna varılmıştır.
