The Concept of Polish Music: In Search of Adequate Criteria
Authors: Golianek Ryszard Daniel 
Published: April 2019

Abstract
The article discusses the notion of Polish music, the possibilities of defining that notion, establishing its scope and listing specific problems related to it. For about 150 years, writers on Polish music have expressed the conviction that it has its own distinctive stylistic and expressive character. Studies concerning the specific qualities of Polish national style after WWII have naturally linked up to Polish music history, mainly that of the 19th century. The new political and cultural situation in Poland after 1989 calls, however, for a change of perspective. We must take into account the present-day cultural situation, in which boundaries are blurred, while supra-national structures and global thinking are beginning to dominate.
The paper attempts to define Polish music as a notion in contemporary discourse on history, to examine the resonance of that category, and to point to artistic phenomena which this notion may be said to describe. I will list and analyse the criteria that have been used to define that notion. Though the problem concerns the history of Polish music at large, the cognitive situation is particularly complex and ambivalent with reference to the 19th century. I will discuss the most common ways of defining the criterion of Polishness in music, namely: the origins and nationality of the composers; their place of activity; references to Polish music traditions, and the expressive qualities of the music itself. In the conclusion, I will present my thesis concerning the possibility of defining Polish music.
Folklorism as an Invention of the State. Contributions of Polish Ethnomusicologists in Historical Perspective
Authors: Dahlig Piotr 
Published: April 2019

Abstract
Folklorism is presented as a component of culture change. The aim of the article is to show how ethno- and musicologists, folklorists, music teachers, broadcasters, and others, have influenced traditional peasant culture in times of fundamental transformation during the 20th century, and how they have contributed to its documentation, understanding and invention of new meanings, including the Polishness of folklore in Poland. This review aims to exemplify this process. Each European country has its own history in this respect. The text consists of three parts. In the first one, folklore is confronted with social history; the second one is dedicated to generations of ethnomusicologists; the third one is dedicated to contemporary functions of music traditions and the role of ethnomusicologists, with emphasis on applied ethnomusicology. The comments on applied ethnomusicology summarise the author’s experiences acquired during field research in Poland since 1975 and attempt to demonstrate how the past (of traditional culture and music, including re/invented national values) is being transformed in the present or, rather, how history fuses with the present time.

Authors: Anand Rao , Vantagodi Nihal Vishnu , Shanbhag Kartik A , Mahesh M 
Published: April 2019

Abstract
Material handling and logistics management that involve transportation of work pieces on production floor are important aspects to manufacturing that affect productivity and efficiency. Tow vehicles that are manually driven are currently used for this purpose. These processes can be better performed through automation. Automated guided vehicle (AGV) is an apt solution. AGVs are unmanned autonomous vehicles that can be programmed to perform versatile tasks. AGVs available in market are imported and hence have high capital cost and increased lead time for spare parts. Proposed AGV is built with a capital cost that is less than half of the existing AGVs. Its design is made indigenously, with most of its parts locally sourced. It can achieve a speed of 0.83 m/s, with a pulling capacity of 1,300 kg. Its rechargeable batteries sustain four hours of continuous operation for one complete discharge. It has been tested and found to effectively replace tow vehicles.
An Overview of Carrier-based Modulation Methods for Z-Source Inverter
Authors: Roomi Muhammad M. 
Published: April 2019

Abstract
Single-stage energy converters, in particular, the Z-Source Inverter (ZSI) or impedance source inverter, has gained significant attention in the recent years. ZSI ensures flexible energy conversions (dc–dc, dc–ac, ac–ac and ac–dc) because of its unique ability to boost the output voltage in typical renewable energy systems. The impedance network integrated between the energy source and the load contributes to the unique functionality of the ZSI. As substantial research has been conducted on the ZSI, this article provides a review on the operation of ZSI. The article initially examines the various topologies commonly adopted for the application of the ZSI. Subsequently, details of the various modulation methods that are commonly used to obtain the voltage boosting using ZSI are documented. Additionally, the phenomenon of neutral point formation, which is an important impediment to the adoption of multilevel ZSIs and the limitation of the modulation methods, is explained.

Published: April 2019

Abstract
Introduction: Since the CT operators play an important role in the diagnosis and treatment of diseases and exposing the patients to radiation exposure, they must be aware of all CT parameters which affect the image quality and patient dose and update their knowledge in parallel with the progresses in CT technology. Therefore, the knowledge of radiographers and CT technologists regarding the CT parameters was assessed in this study to identify and resolve any potential deficiencies.
Material and methods: This study was conducted in 2018 among 113 radiographers and 103 CT technologists in Khuzestan province using a three-part questionnaire containing demographic characteristics, general opinion on CT scan dose and questions assessing technologists’ knowledge of CT exposure parameters. Data were analyzed using SPSS software.
Results: Total knowledge scores of radiographers and CT technologists about CT exposure parameters were 36 and 42, respectively. The highest knowledge score among technologist was the knowledge of changing parameters based on patient characteristics and the lowest was in the field of awareness of noise index and diagnostic reference levels.
Conclusion: Total knowledge scores of radiographers and CT technologists about different scan parameters affecting dose and image quality was very low. Reviewing and updating the content of academic education and holding retraining courses are suggested.

Authors: Khoramian Daryoush , Sistani Soroush , Hejazi Peyman 
Published: April 2019

Abstract
Objective: The literature has approved that the use of the concept of diagnostic reference level (DRL) as a part of an optimization process could help to reduce patient doses in diagnostic radiology comprising the Computed Tomography (CT) examinations. There are four public/governmental CT centers in the province (Semnan, Iran) and, to our knowledge, after about 12 years since the launch of the first CT scanner in the province there is no dosimetry information on those CT scanners. The aim of this study was to evaluate CT dose indices with the aim of the establishment of the DRL for head, chest, cervical spine, and abdomen-pelvis examinations.
Methods: Scan parameters of 381 patients were collected during two months from 4 CT scanners. The CT dose index (CTDI) was measured using a calibrated ionization chamber on two cylindrical poly methyl methacrylate (PMMA) phantoms. For each sequences, weighted CTDI (CTDIw), volumetric CTDI (CTDIv) and dose length product (DLP) were calculated. The 75th percentile was proposed as the criterion for DRL values.
Results: Proposed DRL (CTDIw, CTDIv, DLP) for the head, chest, cervical spine, and abdomen-pelvis were (46.1 mGy, 46.1 mGy, 723 mGy × cm), (13.8 mGy, 12.0 mGy, 377 mGy × cm), (40.0 mGy, 40.0 mGy, 572 mGy × cm) and (14.9 mGy, 12.1 mGy, 524 mGy × cm), respectively.
Conclusion: Comparison with the others results from the other countries indicates that the head, chest and abdomen-pelvis scans in our region are lower or in the range of the other studies investigated in terms of dose. In the case of cervical spine scanning it’s necessary to review and regulate scan protocols to reach acceptable dose levels.

Authors: Javid Zeinab , Norouzy Abdolreza , Bangaleh Zahra , Shadnoush Mahdi 
Published: April 2019

Abstract

Introduction: Skin flap application in the clinical practice is restricted due to the ischemic damage and flap necrosis. Rosmarinus oil has been shown to improve a skin flap survival. In the present work we studied the role of mammalian target of rapamycin (mTOR) signaling on rosmarinus-induced flap protection. Methods: A flap surgery was performed on Sprauge-Dawley rats (8 cm in by 3 cm). A week before and a week after the surgery the flaps were treated with topical rosmarinus oil (twice per day). Rapamycin (m-TOR inhibitor) was administered 30 minutes before the flap surgery in rosmarinus-treated or not treated groups. A week after the surgery the malondialdehyde (MDA) contents, myeloperoxidase (MPO) and superoxide dismutase (SOD) activities, expression of Bax, Bcl-2, mTOR and p-mTOR were measured in the flap tissue. Results: Topical application of the rosmarinus increased the flap survival (p<0.05), anti-oxidative enzyme activity (SOD, p<0.05) and anti-apoptotic protein Bcl-2 expression. Rosmarinus treatment decreased the flap MDA content, MPO activity, and pro-apoptotic protein Bax expression (p<0.05). Rosmarinus topical application did not change mTOR expression and phosphorylation in the flap tissue. Expression of p-mTOR in rosmarinus treated group was suppressed by rapamycin pre-treatment, which also abolished rosmarinus effects on the flap survival (p<0.05). Conclusion: These data suggested p-mTOR dependent mechanism in rosmarinus-induced flap survival.
Dermoscopy of the Month Dermoscopic Features of Sebaceous Nevus - a Report of 4 Cases
Authors: Tirnanić Tanja , Mijušković Željko 
Published: April 2019

Abstract
Sebaceous nevus is a congenital hamartoma commonly associated with the development of secondary neoplasms. It has a predilection for the scalp and less commonly manifests on the face, the neck, and the trunk. The lesions presented in our cases are from the trunk of a 19-year old man, the forehead of a 25-year old man, the scalp of a 22-year old woman and from the face of a 45-year old man. Two of four cases were associated with secondary neoplasms, syringoma and basal cell carcinoma. Dermoscopy of nevus sebaceous demonstrated yellowish-brown globular structures, presenting either singly or in clusters and pink-brown-grey papillary appearance. The specific dermoscopic findings in our case associated with basal cell carcinoma were fine arborizing and serpiginous vessels at the periphery of the lesion and exophytic grey papillary structures. Dermoscopy can be a useful diagnostic tool for diagnosing and monitoring nevus sebaceous in order to detect different tumors associated with nevus sebaceous and avoid unnecessary excisions and scars in aesthetically sensitive locations.

Published: April 2019

Abstract

Aim: The goal of this research is to improve the educational training process in Physical Education and Sport through the development of agility.

Methods: The research was conducted in two secondary schools in Mures County (Măgherani Secondary School and “Mátyus István” Chibed Secondary School) during February and April 2017 on a class of 32 pupils. Subjects were divided in two groups, the control group and the experiment group. As Agility Testing Methods we used the Compass Drill Test and the Arrowhead Drill Test; both tests are part of “SPARQ” - the acronym for Speed, Power, Agility, Reaction and Quickness.

Results: Our results indicate that by using specific agility development exercises, the results of experiment group have increased significantly (p = 0.0000103) compared to control group. In the latter case we used speed exercise only and therefore the increase of results was insignificant (p = 0.17).

Abstract

Introduction: We started from the idea that the association of dietary supplements recommended by specialists and approved by the World Anti-Doping Agency with natural honey-based products, is beneficial for improving body composition and effort capacity in elite rugby players. The main purpose of this study was to determine the type of carbohydrates with the most beneficial effects for recovery and performance.

Materials and methods: The study lasted 30 days and included 30 rugby players from SCM Timisoara Saracens Rugby team. They were randomly divided into 2 groups: the study group who consumed dietary supplements based on apiculture and herbal products, along with classical nutritional supplements and the control group that only used classical supplements. With the help of the InBody 720 Body Composition Analyzer, we evaluated the body composition parameters, and the player’s ability to repeatedly perform high-intensity aerobic work was established with the intermittent Recovery Level 2 YO-YO test.

Results: The results show a significant increase in the average running distance in the fitness test for the study group (p = 0.021) and also for the control group (p = 0.008), with a considerable difference between the groups in terms of running distance (increase by 300 meters versus 208 meters in the control group) but without a significant difference between groups at the end of the study (p = 0.789). Improvements in body composition parameters were found in both groups, but significant differences between groups occurred only in terms of extracellular fluids/total body fluids ratio (p = 0.047) and extracellular water/total water ratio (p = 0.042). The study group showed a significant decrease in total body fat (p = 0.054) and visceral fat area (p = 0.002) and an increase in extracellular water (p = 0.013). The control group experienced a significant decrease in body fat and body fat percentage (p = 0.013 and p = 0.017 respectively), and increase in terms of skeletal muscle mass (p = 0.03), intracellular water (p = 0.03) and total water = 0.032).

Conclusion: The results of this study highlight the importance of the type and quality of nutritional supplements in professional athletes training.
The potential value of kinesio taping for the management of nonspecific low back pain
Authors: Gligor Șerban , Gligor Răzvan 
Published: April 2019

Abstract

Background: Kinesio Taping (KT) is a widely used treatment method in the clinical practice that is also largely applied as a therapy for lumbar pain. The method was invented in 1970 by Kenzo Kase et al. and is represented by the application of adhesive tapes on the skin, that are very thin and with elasticity similar to the skin. Although it is frequently used, the efficacy of kinesio taping is still to be proven, and the mechanism it is based upon still remains unclear. Lumbar pain is a very important health issue worldwide; it is pain in the lumbar-sacral region, at the L4-L5 level. Chronic lumbar pain has a high prevalence across the world, affecting especially patients that are over 45 and being associated with high medical and social costs. The aim of this paper is to present a systematic literature analysis regarding the effects of kinesio taping on lumbar pain and on the degree of disability it can lead to.

Materials and methods: The research is based on the analysis of relevant scientific studies on the effects of kinesio taping on lumbar pain published in different data basis such as NCBI, PubMed, Crossref, Cochrane Library, Scope Med, Net Journals, and Research Gate between 2012 and 2017.

Results: 30 articles were included in the study out of the total number on the topic, articles that correspond with the aim of the study and that present the most recent advancements in the field.

Conclusions: KT generally has effects that are similar with those of traditional treatment methods for lower back pain and for the disabilities it can produce, but results appear much faster; moreover, the efficacy is higher when KT is associated with traditional treatment options.
