In this paper, we report some aspects of the process of the introduction of color to the Colombian television network. Our analytical approach is to see lineal comprehensions, typical of progressive histories of technological change, as problematic. Consequently, we try to take into account heterogeneous arrays of the historical, social, economical, cultural, technical and political circumstances involved in the process. This approach allows us to explain the technological alternatives that were considered and the technical and institutional pathways that were effectively implemented. The historical review suggests that an oversimplified comprehension of socio-technical change gives rise to a low capacity to guide it with respect to more ambitious social goals. ; En el artículo narramos aspectos del proceso de introducción del color en la red colombiana de televisión. Nuestro objetivo analítico consiste en problematizar la comprensión lineal característica de las narraciones históricas progresivas del cambio socio-técnico, mostrando una red heterogénea de circunstancias históricas, sociales, económicas, culturales, técnicas y políticas involucradas en el proceso, las cuales permiten explicar las alternativas tecnológicas consideradas y las trayectorias técnicas e institucionales resultantes. Las conclusiones de la revisión histórica sugieren que una comprensión sobresimplificada del cambio socio-técnico redunda en una baja capacidad para orientarlo de acuerdo con metas sociales ambiciosas.

Introduction: The social aspect of breast cancer presents a serious problem all the time. Quality of women´s life after surgery must be compared to life before it. Breast cancer treatments today are likely to cause less physical deformity from surgery than two decades ago but are more complex and extend over a longer period of time. Non-palpable breast lesions are findings with non-biologically specified importance, which can be responsible for development of cancer. The authors present the diagnosis and the results of the treatment of patients with non-palpable breast lesions. They were hospitalized at the Department of Surgery in Nitra from Jan uary 2014 untilJuly 2017 and we used the SNOLLmethod or wire guided excision under ultrasound control or digital stereotaxic. Results: From January 2014 until July 2017 there were 122 patients diagnosed with non-palpable breast lesions at the Department of Surgery at our hospital. 76 (62.3%) of these patients were diagnosed with carcinoma. Wire Guided Localization was performed in 99 (81.1%) patients; sentinel node was found in 41 (33.6%) patients using the SNOLL method. From all the patients a reoperation was conducted in 4 cases (3.3%) for close or positive margin status and in 3 cases (2.5%) for false negative perioperative sentinel biopsy.                                                                Conclusion: The technique combining 99mTc-MAA (albuminmacro aggregate marked by 99Technecium) and nanocoloid is a reliable localization method for non-palpable lesions and sentinel nodes. SNOLL is a practical and oncological safe technique of excision of a subclinical lesion in combination with sentinel biopsy. This technique brings new visions for the future, especially for quality of life after surgery, changes in body image and sexuality.

Danışman: DR. ÖĞR. ÜYESİ ALİHAN LİMONCUOĞLU Yer Bilgisi: İstanbul Gelişim Üniversitesi / Sosyal Bilimler Enstitüsü / Siyaset Bilimi ve Uluslararası İlişkiler Anabilim Dalı / Güvenlik Araştırmaları Bilim Dalı Konu: Uluslararası İlişkiler = International Relations ; PKK terör örgütünün, 1984-2018 yılları arasında Türkiye'de örgütsel yapılar oluşturarak cebir ve şiddet yoluyla terör eylemleri uyguladığı ve halen devam ettirdiği görülmektedir. PKK terör örgütünün ortaya çıkması ile eylemlerine başlaması dış ülkelerle ilişkilerin çok farklı düzeyde olup desteklerini aldığı görülmüştür. Toplumda terörün şiddet ve korku yaymasıyla birlikte tehdit eden bir yapıyla da karşımıza çıktığı görülmüştür. Bu oluşumun karşısında güvenlik güçleri terörizmle mücadelede etkili ve başarılı olup, birçok şehit vermiştir. Ayrıca terörle mücadelenin sadece askeri ve kolluk güçleriyle değil, toplumun her kesimiyle ortak hareket etme bilincine de sahip olması gerektiği görülmüştür. Terör ve terörizmle mücadelenin askeri, siyasi, kültürel, ekonomik, uluslararası diplomasi ve işbirliği ile sosyal olarak ele alınması önem arz etmektedir. Bu tez çalışmasının amacı, ilk bölümde terör, terör örgütü ve terörizmin anlaşılması konusu incelenmiştir. İkinci bölümde, PKK terör örgütü teşkilatının kurulmasının ardından dış bağlantılarla ilişkisi ve örgüt elebaşı kurucu üyesi Abdullah Öcalan'ın getirilmesi incelenmiştir. Son bölümde ise, terörün Türkiye'ye medya ve basın yayın yoluyla ülkemize sosyolojik ve psikolojik yönden etkilerinin yansıması analiz edilmiştir. Yapılan çalışma sonucunda, Terör örgütü eylemlerinin psikolojik savaş olarak topluma yansıması acıları da beraberinde getirmiş, sosyal problemler ve psikolojik problemler toplumu olumsuz yönde etkilediği görülmüştür. ; PKK terrorist organization has set up organizations in Turkey between 1984 and 2018. Violent terror attacks still continue today. PKK has managed gain support from foreign actors depending on its ability to form international bonds. It is obvious that society felt threatened by the actions of the terrorist group which used violence and intimidation as a tool. Security forces have fought a succesful battle against thi organization however has suffered many casualties.

In this study, it has been seen that the acts of terrorist organization as a psychological war have brought the pain to the society and social problems and psychological problems negatively affect the society.

The article is the first in a series of works presenting the potential and possibilities of using for energy purposes wood waste and wood by-products generated at various stages of production in companies of the wood industry. The management of all wood waste and wood by-products is a pending issue due to the growing importance of the circular economy and broadly understood environmental protection. It is the environmental aspects and the climate targets defined by the EU that are the basis to determine the precise courses of action for the Member States and, as a result, also for companies. The article proves that regardless of the decisions taken by governments of individual countries in terms of broadly understood environmental protection, companies are free to implement pro-environmental solutions as part of their business activity. Due to the broad subject of the management of waste and by-products generated in different units of the wood industry, the possibilities of their use in terms of energy in primary wood processing companies–sawmills—are presented first. On the example of selected entities, the energy potential and possibilities of generating energy from renewable sources taking into account the principles of circular economy are presented. The possibilities of optimising production by improving redistribution of thermal energy, which may result in improving the economic efficiency of the assessed enterprises, were indicated.
