Semiconductor devices are usually formed on a single silicon wafer during a batch processing method. Individual devices are separated from the wafer during the wafer sawing or dicing step. Subsequent packaging processes are then performed on the individual devices, whose edge portions are very susceptible to mechanical damage from the sawing process. Defects formed along device edges due to the dicing saw blade often provide potential sites for serious reliability problems. If the scribing area is reduced, the number of the separated devices from a single wafer increases, which results in productivity improvement. However, the closer the scribing position of the saw blade comes to the active device pattern, the greater possibility of sawing-induced damage to the active pattern is. Thus, this work shows methods to reduce the negative impact of the saw blade while maintaining close proximity of the scribe lines to the IC devices. In particular, this work suggests that a decrease in the size of the diamond particles embedded in the saw blade and in the rotation speed of the saw blade might contribute to the prevention of sawing-induced damage to device patterns.

The purpose and tasks of the work are to analyze the contemporary Ukrainian mass culture in terms of its value and humanistic components, as well as the importance of cultural studies and Ukrainian studies in educational disciplines for the formation of a holistic worldview of modern youth.Analysis of research and publications. Scientists repeatedly turned to the problems of the role of spirituality in the formation of society and its culture. This problem is highlighted in the publications by O. Losev, V. Lytvyn, D. Likhachev, S. Avierintsev, M. Zakovych, I. Stepanenko and E. Kostyshyn.Experts see the main negative impact of mass culture on the quality approach, which determines mass culture through the market, because mass culture, from our point of view, is everything that is sold and used in mass demand.One of the most interesting studies on this issue was the work by the representatives of Frankfurt School M. Horkheimer and T. Adorno «Dialectics of Enlightenment» (1947), devoted to a detailed analysis of mass culture. Propaganda at all socio-cultural levels in the form is similar in both totalitarian and democratic countries. It is connected, according to the authors, with the direction of European enlightenment. The tendency to unify people is a manifestation of the influence of mass culture, from cinema to pop. Mass culture is a phenomenon whose existence is associated with commerce (accumulation in any form – this is the main feature of education), in general, the fact that it exists in this form is related to the direction of the history of civilization.Modern mass culture, with its externally attractive and easily assimilated ideas and symbols, appealing to the trends of modern fashion, becomes a standard of prestigious consumption, does not require intense reflection, allows you to relax, distract, not teach, but entertains, preaches hedonism as the main spiritual value. And as a consequence, there are socio-cultural risks: an active rejection of other people, which leads to the formation of indifference; cruelty as a character trait; increase of violent and mercenary crime; increase in the number of alcohol and drug addicts; anti-patriotism; indifference to the values of the family and as a result of social orphanhood and prostitution.Conclusions, perspectives of research. Thus, we can conclude that modern Ukrainian education is predominantly formed by the values of mass culture. Namely, according to the «Dialectic» by Horkheimer and Adorno, «semi-enlightenment becomes an objective spirit» of our modern society.It is concluded that only high-quality education can create the opposite of the onset of mass culture and the destruction of spirituality in our society. It is proved that only by realizing the importance of cultivating disciplines in the educational process and the spiritual upbringing of the nation, through educational reforms, humanitarian knowledge will gradually return to student audiences.Formation of youth occurs under the influence of social environment, culture, education and self-education. The optimal combination of these factors determines both the process of socialization itself and how successful it will be. In this context, one can see the leading role of education and upbringing. It turns out that the main task of modern education is to spread its influence on the development of spiritual culture of the individual, which eventually becomes a solid foundation for the formation of the individual. Such a subject requires both philosophical and humanitarian approaches in further integrated interdisciplinary research, since the availability of such research will provide the theoretical foundation for truly modern educational and personal development.

The urgency of the researched problem is connected with the growing role of mass media in modern conditions leads to change of values and transformation of identity of the person. The active growth of the role of the media, their influence on the formation and development of personality leads to the concept of “media socialization” and immutation in the media. The aim of the study is to outline the possibilities of the process of media socialization in the context of immutation in the media. The methods of our research are: analysis of pedagogical, psychological, literature, synthesis, comparison, generalization. The article analyzes the views of domestic and foreign scientists on the problem of immutation in the media and the transformation of the information space. In the context of the mass nature of the immutation of society, the concept of “media socialization” becomes relevant, which is the basis for reducing the negative impact of the media on the individual.The author identifies the lack of a thorough study of the concept of “media socialization” in modern scientific thought. Thus, media socialization is associated with the transformation of traditional means of socialization, and is to assimilate and reproduce the social experience of mankind with the help of new media.The article analyzes the essence of the concepts “media space”, “mass media” and “immutation”. The influence of mass media on the formation and development of the modern personality is described in detail.The study concluded that it is necessary to form a media culture of the individual, to establish safe and effective interaction of young people with the modern media system, the formation of media awareness, media literacy and media competence in accordance with age and individual characteristics for successful media socialization. The role of state bodies in solving the problem of media socialization of the individual was also determined. It is determined that the process of formation of media culture in youth should take place at the level of traditional institutions of socialization of the individual.The author sees the prospect of further research in a detailed analysis and study of the potential of educational institutions as an institution and a means of counteracting the mass nature of the immutation of society.Key words: immutation, media socialization, mass media, media space, information.

Purpose The purpose of this paper is to study the differentiated impact of factors that influence the propensity to entrepreneur in a sample of people in Chile. A distinction is made between individuals that live in primary cities and secondary cities. The differentiating factors are socio‐cultural aspects (reference models – positive examples of entrepreneurs – and perception of social fear of failure) and the gender of the individual. Design/methodology/approach For the research data from the survey used in Chile by the Global Entrepreneurship Monitor for the years 2010 and 2011 were used. A logit model was used to determine the differentiated impact of the analysed factors and interactions were done using the method proposed by Corneliâen and Sonderhof (2009). Findings These showed that the fact that an individual lives in a secondary city decreases his entrepreneurship probability. The positive impact that the reference models have is weaker in women. Contrary to what was expected, the negative impact of the fear of failure perception is weaker in women. Practical implications These results have the implications to suggest focused public policies and differentiations that consider the socio‐cultural, territorial (focused in cities) and gender aspects. Originality/value The research contributes by giving empirical evidence of the existence of the negative impact of living in a secondary city and of differentiated effects of socio‐cultural factors from the gender perspective.

AbstractThis review article is a summary of the current knowledge in the field of plastic coloring. Plastics belong as well as paints, coatings, printing inks, and cosmetic formulations to the most important application systems for colorants, both for pigments and dyes. Colorants have to meet increasing demands in plastic applications due to the growing number of polymers with specific properties. Crucial factors besides the plastic type are the processing method and the required fastness level. Among the most important polymers for coloring with pigments and dyes are polyolefins, polyvinyl chloride, polyurethane, polyamide, polycarbonate, polyester, and elastomers. Different processing methods are used for coloring of the individual plastics. The coloring processes need to be coordinated in accordance with the steps of the plastics processing leading to the final product.

Construction industry creates an environment for people's lives. On the other hand, construction activities have a negative impact on various aspects of the environment. It consumes natural raw materials, significantly contributes to carbon footprint, waste, etc. Appropriate choice of constructional, material, technical, technological and environmental parameters of buildings can partially reduce this negative impacts. By designing, implementing and using wood-based constructions it is possible to reduce the negative impact in the area of construction waste generation. Currently, the construction market offers a large number of construction systems of wooden buildings, which have both strengths and weaknesses. In this paper are identified construction systems of wooden buildings offered on the Slovak construction market. The aim of the paper is a detailed identification of construction waste generation during the realization of particular wooden structures and monitoring of waste generation in production factory (off site) and on construction site (on site) during the construction of wooden buildings. Based on the obtained information, the individual construction systems of wood-based constructions are compared in terms of construction waste generation

Protection of the natural environment is a key activity driving development in the transport discipline today. The use of simulators to train civil aviation pilots provides an excellent opportunity to maintain the balance between efficiency and limit the negative impact of transport on the environment. Therefore, we decided to determine the impact of selected simulations of air operations on energy consumption. The aim of the research was to determine the energy consumption of the flight simulator depending on the type of flight operation and configuration used. We also decided to compare the obtained result with the energy consumption of an aircraft of a similar class, performing a similar aviation operation and other means of transport. In order to obtain the results, a research plan was proposed consisting of 12 scenarios differing in the simulated aircraft model, weather conditions and the use of the simulator motion platform. In each of the scenarios, energy consumption was measured, taking into account the individual components of the simulator. The research showed that the use of a flight simulator has a much smaller negative impact on the natural environment than flying in a traditional plane. Use of a motion platform indicated a change in energy consumption of approximately 40% (in general, flight simulator configuration can change energy consumption by up to 50%). The deterioration of weather conditions during the simulation caused an increase in energy consumption of 14% when motion was disabled and 18% when motion was enabled. Energy consumption in the initial stages of pilot training can be reduced by 97% by using flight simulators compared to aircraft training.

Background: Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are severe body image disorders that severely interfere with the daily functioning of the individual. They are separate but overlapping nosologically entities. There is a study on the tendency of wrong eating behaviour in adolescents with specifications for anorexia nervosa in Jakarta 11.6% and there is also a study at High School in Jakarta 88.5% of adolescents experience wrong eating behaviour with the specifications of anorexia nervosa. And the two largest epidemiological surveys regarding BDD, there were 2.5% women and 2.2% men. With a fairly high number of these two events, this has the potential to have a negative impact on someone’s health. This study aims to discuss the impact of anorexia nervosa. Methods: The researcher used several literature and scientific journals, which was based on 15 journals and literature, discussing a tendency to anorexia nervosa with the incidence of Body Dysmorphic Disorder and its medical emergencies. Conclusion: There is a correlation of anorexia nervosa among teenager especially girl teenage

Coinfecting parasites and pathogens remain a leading challenge for global public health due to their consequences for individual-level infection risk and disease progression. However, a clear understanding of the population-level consequences of coinfection is lacking. Here, we constructed a model that includes three individual-level effects of coinfection: mortality, fecundity, and transmission. We used the model to investigate how these individual-level consequences of coinfection scale up to produce population-level infection patterns. To parameterize this model, we conducted a 4-y cohort study in African buffalo to estimate the individual-level effects of coinfection with two bacterial pathogens, bovine tuberculosis (bTB) and brucellosis, across a range of demographic and environmental contexts. At the individual level, our empirical results identified bTB as a risk factor for acquiring brucellosis, but we found no association between brucellosis and the risk of acquiring bTB. Both infections were associated with reductions in survival and neither infection was associated with reductions in fecundity. The model reproduced coinfection patterns in the data and predicted opposite impacts of coinfection at individual and population scales: Whereas bTB facilitated brucellosis infection at the individual level, our model predicted the presence of brucellosis to have a strong negative impact on bTB at the population level. In modeled populations where brucellosis was present, the endemic prevalence and basic reproduction number (R0) of bTB were lower than in populations without brucellosis. Therefore, these results provide a data-driven example of competition between coinfecting pathogens that occurs when one pathogen facilitates secondary infections at the individual level.

The experiences and marginalisation of international organisation employees with caring responsibilities has a direct negative impact on the type of security and justice being built in conflict-affected environments. This is in large part because international organisations fail to respond to the needs of those with caring responsibilities, which leads to their early departure from the field, and negatively affects their work while in post. In this toolkit we describe this problem, the exacerbating factors, and challenges to overcoming it. We offer a theory of change demonstrating how caring for carers can both improve the working conditions of employees of international organisations as well as the effectiveness, inclusivity and responsiveness of peace and justice interventions. This is important because it raises awareness among employers in the sector of the severity of the problem and its consequences. We also offer a guide for employers for how to take the caring responsibilities of their employees into account when developing human resource policies and practices, designing working conditions and planning interventions. Finally, we underscore the importance of conducting research on the gendered impacts of the marginalisation of employees with caring responsibilities, not least because of the breadth and depth of resultant individual, organisational and sectoral harms. In this regard, we also draw attention to the way in which gender stereotypes and gender biases not only inform and undermine peacebuilding efforts, but also permeate research in this field. Our toolkit is aimed at international organisation employees, employers and human resources personnel, as well as students and scholars of peacebuilding and international development. We see these communities of knowledge and action as overlapping, with insights to be brought to bear as well as challenges to be overcome in this area. The content of the toolkit is equally relevant across these knowledge communities as well as between different specialisms and disciplines. Peacebuilding and development draw in experts from economics, politics, anthropology, sociology and law, to name but a few. The authors of this toolkit have come together from gender studies, political science, and development studies to develop a theory of change informed by interdisciplinary insights. We hope, therefore, that this toolkit will be useful to an inclusive and interdisciplinary set of knowledge communities. Our core argument - that caring for carers benefits the individual, the sectors, and the intended beneficiaries of interventions - is relevant for students, researchers, policy makers and practitioners alike.
