This Technical Report was reaffirmed March 2021.
A working knowledge of contraception will assist the pediatrician in both sexual health promotion as well as treatment of common adolescent gynecologic problems. Best practices in adolescent anticipatory guidance and screening include a sexual health history, screening for pregnancy and sexually transmitted infections, counseling, and if indicated, providing access to contraceptives. Pediatricians’ long-term relationships with adolescents and families allow them to help promote healthy sexual decision-making, including abstinence and contraceptive use. Additionally, medical indications for contraception, such as acne, dysmenorrhea, and heavy menstrual bleeding, are frequently uncovered during adolescent visits. This technical report provides an evidence base for the accompanying policy statement and addresses key aspects of adolescent contraceptive use, including the following: (1) sexual history taking, confidentiality, and counseling; (2) adolescent data on the use and side effects of newer contraceptive methods; (3) new data on older contraceptive methods; and (4) evidence supporting the use of contraceptives in adolescent patients with complex medical conditions.

Published: September 2014

Purpose :
Ectopia lentis (EL) is a major criteria for the diagnosis of Marfan syndrome, it may vary from an asymptomatic mild displacement to a significant subluxation that places the equator of the lens in the pupillary axis. The purpose of this work is to present the case of a patient with Marfan syndrome who received treatment for subluxation at our institution.

Case Report :
A 51-year-old female diagnosed with Marfan syndrome presented to the emergency department with bilateral eye redness, foreign body sensation and crusting around the eyes on awakening. She had the following history of cardiac and ophthalmologic complications, including: 1. Lens subluxation 2. High myopia 3. Aortic root dilation, 4. Mitral valve prolapse and 5. Tricuspid insufficiency.

Conclusion :
The ophthalmological management of Marfan patients is challenging and periodical follow-up is needed. Surgical versus conservative management is controversial, each case needs to be evaluated individually to analyze the risks and benefits of the procedures.
Surface Roughness and Gloss of Actual Composites as Polished With Different Polishing Systems
Authors: Rodrigues-Junior SA , Chemin P , Piaia PP , Ferracane JL 
Published: September 2014

SUMMARY
Objective: This in vitro study evaluated the effect of polishing with different polishing systems on the surface roughness and gloss of commercial composites. Methods: One hundred disk-shaped specimens (10 mm in diameter × 2 mm thick) were made with Filtek P-90, Filtek Z350 XT, Opallis, and Grandio. The specimens were manually finished with #400 sandpaper and polished by a single operator using three multistep systems (Superfix, Diamond Pro, and Sof-lex), one two-step system (Polidores DFL), and one one-step system (Enhance), following the manufacturer's instructions. The average surface roughness (μm) was measured with a surface profilometer (TR 200 Surface Roughness Tester), and gloss was measured using a small-area glossmeter (Novo-Curve, Rhopoint Instrumentation, East Sussex, UK). Data were analyzed by two-way analysis of variance and Tukey's test (α=0.05). Results: Statistically significant differences in surface roughness were identified by varying the polishing systems (p&lt;0.0001) and by the interaction between polishing system and composite (p&lt;0.0001). Pairwise comparisons revealed higher surface roughness for Grandio when polished with Sof-Lex and Filtek Z250 and Opallis when polished with Enhance. Gloss was influenced by the composites (p&lt;0.0001), the polishing systems (p&lt;0.0001), and the interaction between them (p&lt;0.0001). The one-step system, Enhance, produced the lowest gloss for all composites. Conclusions: Surface roughness and gloss were affected by composites and polishing systems. The interaction between both also influenced these surface characteristics, meaning that a single polishing system will not behave similarly for all composites. The multistep systems produced higher gloss, while the one-step system produced the highest surface roughness and the lowest gloss of all.

Landscape structure changes in the Slepiotka River drainage basin in the period 1824-1993 (The Silesian Upland, Poland)
Authors: Mazurek Kinga 
Published: September 2014

Abstract
The area of the Upper Silesian Coal Basin is the most important underground mining district in Poland. Coal mines, operating in the area since the eighteenth century, have contributed to massive transformations of the landscape structure. River valleys within range of intensive exploitation activities have been undergoing vast changes. The Slepiotka River drainage basin constitutes an interesting regional example of transformations in the river's watercourse as well as in its adjacent area. It is a left-hand tributary of the Klodnica River with a length of about 8.6 km.
Changes in the landscape structure that occurred between 1824-1993 have been analyzed. The starting material consisted of topographical maps that were digitized and calibrated and served as a basis to create colorful compositions. The areas occupied by the different land cover types have been calculated, which allowed to determine their participation in the drainage basin.
In about 169 years, significant changes took place in the area of research considering the share of different types of cover and land use. During this time, the river changed its course, both naturally and by human activities. Increasing urbanization and technological development contributed to the diametrical transformation of the landscape structure in the discussed area
Vanishing Point - or Meeting in the Middle? Student/Supervisor Transformation in a Self-Study Thesis
Authors: Pratt Dee , Peat Beth 
Published: September 2014

Abstract
This account explores the divergent perspectives of supervisor and student interacting in self-study research, showing how both participants were transformed by the experience. Although both supervisor and student had faced similar problems as mature students engaging in doctoral study, and both possessed strong convictions about their chosen paths, their focus was very different. The student, being visually creative, was investigating the value of integrated arts as a transformational learning medium; the supervisor, from a linguistics background, was focused on exploring the nature of written communication. The supervisor/student relationship comprises a complex nexus of interconnections between persons, material objects, times and places: it is never static, but always emerging, with the relationship often ending up being more collegial than at first, as with the authors of this paper. In the counterpoint dialogue presented by student and supervisor, it can be seen that both learned from each other: the student, the rigours of structuring a passionate argument intellectually; the supervisor, to express an intellectual argument more personally. Both authors were transformed by the supervisor/student interaction: the supervisor, in rediscovering the value of interpersonal communication; the student, in mastering a research approach which did justice to her belief in the creative power of the arts. The value of engaging with perspectives which initially appear to be irreconcilable is not just to ‘learn new things’, but to push the inner limits of our perspectives, transforming not only the ways in which we perceive things, but the ways in which we learn.
What can the ‘Transpersonal’ Contribute to Transformative Research?
Authors: Walton Joan 
Published: September 2014

Abstract
Since Mezirow, there has been considerable research into transformative learning. However the research methods generally used have been of the same kind that are drawn on to inquire into any area of interest. A key aim of this journal is to explore the transformative possibilities of research, and in the process to investigate creative methods which are expanding and transforming our understanding of what constitutes valid research in a postmodern world. In this context, where the assumptions and worldview of classical Newtonian science are being fundamentally challenged, the idea of the ‘transpersonal’ is receiving increasing attention, particularly within the field of psychology. This paper explains the origins of interest in the transpersonal, and provides an introduction to some emerging research methods which accept the idea of the transpersonal as valid. It concludes with the recognition that for many it will require a transformative shift in thinking and beliefs to accept a transpersonal worldview. However recent findings suggest that engaging in research which is accepting of this worldview can be truly transformative in its outcomes for the researcher, the research participants, and for the reader.

Abstract
The aim of this paper is comparing all possible scenarios to improve the performance of agricultural supply chain (ASC). For this purpose, at first all scenarios is discussed and the main constraints, i.e. available budget and time, is considered. In this study the drivers to improve the performance of ASC is select and distribute the best agricultural service packages in the target ASC. All discussed scenarios need a selection procedure. So a multilevel approach is developed to select the best service package for each scenario. All selection methods are based on performance measurement which had been selected in first level of the approach. Fuzzy decision making and Analytic Hierarchy Process have been used for the approach. A numerical example is solved at the end of the paper to show the capability of the approach and comparing the scenarios.
Features in Angiographic Evaluation of the Diabetic Patient
Authors: Taisia Tiron Andreea , Aron Gheorghiļa 
Published: September 2014

Abstract
Currently it is estimated that there are over 382 million patients with diabetes worldwide and their number is increasing, which makes this metabolic disorder the most common non-contagious disease, particularly related to obesity and physical inactivity. There is a close relationship between diabetes and cardiovascular disease, statistics showing that over 50% of deaths in patients with diabetes are produced by cardiovascular complications. This requires a close collaboration between diabetologists and cardiologists. The mortality caused by atherosclerotic complications is 65-80% for diabetic patients compared to 33% in non-diabetic patients. Moreover, 20% of the patients requiring coronary revascularization procedures are diabetics and over 30% of patients with angiographic exploration have diabetes. Among the patients with diabetes the coronary lesions are present in 50% of cases and the peripheral arteries lesions in 30% of cases.
The Gutenberg galaxy and its “twilight” in the context of contemporary electronic media
Authors: Gálik Slavomír , Tolnaiová Sabína 
Published: September 2014

Abstract
In this article, the authors are concerned with the question of the nature of print and the impact print has on shaping the collective mentality, especially in the context of the electronic media “boom”. Based on their analysis, they state that print has, since its creation, promoted a subject-object dualism, the development of abstract, linear thinking and the shaping of a collective mentality. Print is currently already under the strong, paradigmatic influence of electronic media resulting in a qualitatively new kind of “reading”. That is to say that the electronic media cyberspace encourages the “hyper-textual” interlinking of different kinds of information in our learning or thinking, which can be referred to as “rhizomorphic”. This kind of process is bound up with non-linear “reading”, where the image dominates the word in cyberspace. The electronic media cyberspace thus dominates and shapes the contemporary collective mentality in our culture, including its approach to print.

Authors: Kubátová Jaroslava , Kukelková Adéla 
Published: September 2014

Abstract
This article presents our research into cultural differences in the motivation of Generation Y knowledge workers. The goal of our research was to verify whether the motivation of young knowledge workers (members of Generation Y) could be assessed only in relation to the specifics of their generation, or whether it is necessary to take their national cultural background into account as well. The research carried out among two hundred respondents in four countries has confirmed that it is essential to take into account both generation differences and cultural differences.
Biographical research in social work
Authors: Kozlová Lucie , Hrušková Martina 
Published: September 2014

Abstract
This paper looks at the possibilities of using biographical research in social work focusing on the elderly. Social work with the elderly uses or should use biographical data to create individual plans for clients or for the purpose of sensory activation. Narrative interviews are a form of interaction between a senior client and a social worker. The social worker supports the senior’s narrative so they can view their life for themselves and explain its meaning from their own perspective. The use of sensory activation in social work is only possible when the individual’s identity is supported by a sufficient amount of environmental stimuli, which can be achieved only by acquiring and analyzing data on the life events of the individual. The paper contains examples of the use of biographical data in social work with the elderly, which is essential for further structuring their lives.
Genetic evolution of programs
Authors: Kollár Ján , Pietriková Emília 
Published: September 2014

Abstract
We present evolutionary approach to program development based on absorption of genetic strings at different metalevels. Introducing the principles of software evolution as processes of semantical stability, expansion and contraction, we continue with an example illustrating how it is possible to integrate metalevel with base level and how this integrated computation works when driven by genetic string of codons, determining decisions for program construction and the result of constructed program execution. Next, we analyse the evolutionary circle at metalevel and we show that mentioned expansion and contraction is possible. The main contribution of the paper is that it breaks classic boundaries between models and programs because formal binding of metalevels and base level have been reached.

This paper analyses basic concept of elastic cluster as a hybrid solution of high-performance computing tasks for computing grid and cloud. The analysis is focused on the context of managing resources and tasks in the elastic cluster. In this work design, model and implementation of scheduling algorithm is described. The scheduling algorithm is based on particle swarm optimization (PSO) and hill climbing (HC) optimization and it is appropriate combination of good features the both methods. The algorithm is implemented on HPC cluster into the resource manager Torque. There is included methodology of measurement and evaluation of the algorithm. The paper presents methods of verifying behaviour of algorithm for different tasks requirements, which are typical for grid or elastic cluster. We compare suitability of the proposed algorithm with known solutions. On the base of analysed results is confirmed that proposed algorithm better satisfies specific criteria of elastic cluster.

Authors: Lange Axel , Hentschel Manfred P. , Kupsch Andreas , Hilger André , Manke Ingo , Lück Sebastian , Ulm Volker Schmidt , Grothausmann Roman 
Published: September 2014

Kurzfassung
Typische „Missing Wedge“(MW)-Artefakte in Rekonstruktionen der Computertomografie können mit dem iterativen DIRECTT-Algorithmus (Direkte iterative Rekonstruktion computertomografischer Trajektorien) unterdrückt werden. Die durch fehlende Projektionswinkel bedingten MW-Restriktionen betreffen bisher nur Sonderapplikationen der Röntgen- und Neutronentomografie, müssen in der Nanometer auflösenden Elektronentomografie jedoch als Standard akzeptiert werden. Die MW-Artefakte werden besonders effektiv mit einer spezifischen DIRECTT-Prozedur partiell diskreter Zwischenlösungen beseitigt. Für die Beurteilung der Abbildungsqualität werden Rekonstruktionen von vollständigen und unvollständigen Mess- und Modell-Datensätzen erzeugt und mit Ergebnissen anderer Algorithmen (gefilterte Rückprojektion (FBP) und ART-Methoden) verglichen. Die Fourier-Transformierten der Rekonstruktionen demonstrieren die erfolgreiche Ergänzung der fehlenden Information im MW-Bereich. Die quantitative Bewertung der lokalen Rekonstruktionsqualität mit Methoden der räumlichen Statistik ergibt auch für unterschiedliche Signal-Rausch-Verhältnisse signifikante Vorteile gegenüber FBP und ART.
Mechanical and Thermal Properties of a Cu-CNT Composite with Carbon Nanotubes Synthesized by CVD Process
Authors: Güler Ömer 
Published: September 2014

Abstract
In this study, carbon nanotubes at 0.05–1 wt-% ratios reinforced pure copper powder. Carbon nanotubes (CNT) were used to reinforce the copper matrix, these materials were synthesized under laboratory conditions. Ultrasonic processes and ball-milling method were used to provide a homogenous dispersion during production of the Cu-CNT composite. The Cu-CNT composite powder was produced as bulk material and then, the thermal conductivity as well as the microhardness of the composite were measured. As a particular result, it turned out that the thermal conductivity and the hardness of the composite increased up to a specific ratio of the CNT reinforcement, while the reinforcement ratio exceeding this critical level provided an adverse effect.

Published: September 2014

Abstract
In this study, the fracture toughness of Fe2B boride layer on boronized AISI 304 stainless steel was investigated. Samples were boronized in an indirect heated fluidized bed furnace with Ekabor 1™ boronizing agent at 1123 K, 1223 K, and 1323 K for 1 h, 2 h, and 4 h, respectively. The boride phases were investigated by X-ray diffraction (XRD) analysis. Hardness and fracture toughness of borides were measured via Vickers indentation. With increasing boriding temperature and time the fracture toughness values were reduced. The boride layer thickness formed on the boronized samples ranged between 12 μm and 176 μm. The hardness of the borides ranged between 1709 HV0.1 and 2119 HV0.1 and fracture toughness was in the range of 2.19–4.47 MPa × m1/2 depending on the layer thickness and hardness.
Evaluation of HAZ Hardness in MMA Welding*
Authors: Bodea Marius , Brânduşan Liviu , Mureşan Radu 
Published: September 2014

Abstract
In this paper the primary objective was to establish a new and robust mathematic model that can be used to estimate the hardness in the heat affected zone of manual metal arc welds of low alloyed steels. The mathematical model was checked using a large database of experimental data, containing data for more than 1600 runs. Beside the conventional approaches using carbon equivalent formula, very sensitive coefficients have been included in the model that take into account the smallest chemical influence on the materials, like the oxygen content in ppm or other different elements such as Ti that can have a significant influence on the microstructure and mechanical properties of the welds. Also, the main welding parameters were considered in the mathematical model as primary variables and were combined with the chemical composition in a unitary formula.
