Evaluation of the parameters of importance for quality of life of laryngectomized patients.

Uvod:Kvalitet života trenutno predstavlja najaktuelniji koncept savremene nauke i smatra se idealom moderne medicine. Holistički pristup lečenju čoveka a ne samo bolesti igra značajnu ulogu u ostvarenju koncepta kvaliteta života povezanog sa zdravljem. Kvalitetu života laringektomisanih bolesnika u našoj sredini nije posvećena adekvatna pažnja. Totalna laringektomija kao veoma mutilantna operacija dovodi do drastičnih promena u kvalitetu života. Multidisciplinarni rehabilitacioni program je neophodan laringektomisanim bolesnicima da bi poboljšali kvalitet života. Fonijatrijska rehabilitacija je najznačajniji vid rehabilitacije jer omogućava uspostavljanje verbalne komunikacije. Rehabilitacioni tim koga čine fonijatri, logopedi, psiholozi i medicinske sestre zaslužan je za uspešnu rehabilitaciju oko 87% laringektomisanih pacijenata koji su savladali ezofagusni glas i govor. Psihološka rehabilitacija omogućava resocijalizaciju, povratak u porodično okruženje i društvene aktivnosti. Plod ove studije je i konačno formirano Udruženje laringektomisanih pacijenata Srbije. Ciljevi studije:1.Proceniti demografske i kliničke karakteristike laringektomisanih bolesnika i ispitati faktore od značaja za kvalitet života laringektomisanih bolesnika; 2.Evaluirati karakteristike ezofagusnog glasa i govora i izvršiti objektivizaciju kvaliteta uspostavljanja alarinksnog govora; 3.Proceniti osnovne psihometrijske karakteristike upitnika EORTC QLQ –C30 i EORTC QLQ H&N 43. Materijal i metode: Istraživanje je sprovedeno u Klinici za otorinolaringologiju i maksilofacijalnu hirurgiju Kliničkog centra Srbije u Beogradu u periodu od 01. marta 2012. do 01. marta 2015. godine. Ispitivanjem je obuhvaćeno 223 pacijenta kojima je zbog verifikovanog karcinoma larinksa učinjena totalna laringektomija u Klinici za otorinolaringologiju i maksilofacijalnu hirurgiju Kliničkog centra Srbije a fonijatrijska rehabilitacija je sprovedena u Odseku za fonijatriju Klinike. U okviru istraživanja pacijenti su podeljeni u dve grupe: • Prvu grupu je predstavljalo 168 laringektomisanih pacijenata koji su prošli sve planirane faze fonijatrijske rehabilitacije...Introduction: Quality of life currently represents the most modern concepts of science and it is considered the ideal of modern medicine. A holistic approach to the treatment of the human, not only a disease, plays an important role in the realization of the concept of health related to quality of life. In our community we do not pay adequate attention to the quality of life of laryngectomized patients. Total laryngectomy as a mutilant operation leads to drastic changes in life quality. A multidisciplinary rehabilitation program is essential for the laryngectomized patients to improve their quality of life. Phoniatric rehabilitation is the most important aspect of rehabilitation because it allows the restitution of verbal communication. Rehabilitation team, consisting of phoniatricians, speech therapists, psychologists and nurses, was responsible for the successful rehabilitation of about 87% of laryngectomized patients who have mastered the esophageal voice and speech. Psychological rehabilitation allows the resocialization, return to the family environment and social activities. The yield of this study is the final establishment of the Association of laryngectomized patients of Serbia. Objectives of the study: 1.Evaluate the demographic and clinical characteristics of laryngectomized patients and examine important factors for the life quality of laryngectomized patients; 2.Evaluate characteristics of esophageal voice and speech and perform objectification of quality established alaryngeal speech; 3.Evaluate basic psychometric characteristics of the questionnaire EORTC QLQ - C30 and EORTC QLQ H&N43. Material and Methods: The study was conducted at the Clinic of Otorhinolaryngology and Maxillofacial Surgery, Clinical Center of Serbia in Belgrade, in the period from 1st March 2012 to 1st March 2015. The study included 223 patients, who were verified laryngeal cancer and underwent total laryngectomy in the Clinic of Otorhinolaryngology and Maxillofacial Surgery, Clinical Center of Serbia and phoniatric rehabilitation was conducted in the Phoniatric Department. In this study the patients were divided into two groups: • The first group consisted of 168 laryngectomized patients who underwent all planned phases of phoniatric rehabilitation..

Functionalization of academic content concerning carboxylic acids

Istraživanja [1, 2, 3, 4] su pokazala da se učenici srednjih škola suočavaju s problemima u učenju gradiva organske hemije, posebno s primenom ovih znanja u različitim kontekstima. Jedan od osnovnih uzroka je sama koncepcija nastave organske hemije, koja se prvenstveno svodi na izlaganje akademskih znanja u gotovom vidu [2, 3]. U situacijama kada se učenicima prenosi obimno i kompleksno gradivo, najčešće motivacija za učenje nije velika. Akademska znanja iz organske hemije nisu od velikog značaja učenicima, ukoliko oni ne uviđaju kako mogu da ih iskoriste za unapređivanje kvaliteta svakodnevnog života i pripremu za bavljenje budućom profesijom [1, 3, 4]. Da bismo utvrdili da li izlaganje gradiva organske hemije u kontekstu svakodnevnog života i različitih profesija može da doprinese poboljšanju učeničkih postignuća i funkcionalizaciji stečenih znanja, sproveli smo pedagoški eksperiment sa paralelnim grupama, sa učenicima trećeg razreda gimnazije prirodnomatematičkog smera, u kome je ovaj inovativni pristup nastavi iskorišćen za obradu nastavne teme Karboksilne kiseline i njihovi derivati. Utvrdili smo da primena ovog pristupa dovodi do statistički značajnog poboljšanja učeničkih postignuća i njihove sposobnosti za primenu stečenih znanja iz ove oblasti organske hemije u različitim životnim kontekstima.Research [1, 2, 3, 4] has indicated that high school students have problems related to the learning of organic chemistry content, particulary problems associated with the application of acquired knowledge in a variety of contexts. One of the main causes of this problem is the very conception of organic chemistry courses, which are primarely based on transmission of academic content [2, 3]. In situations where students are exposed to an extensive and complex teaching material, their motivation for learning usually isn’t high. Furthermore, academic content of organic chemistry is not relevant to students, if they are not aware of how they can use it to improve the quality of their everyday life, or whether mastery of this content is important for their future professions [1, 3, 4]. To determine whether teaching organic chemistry in the context of everyday life, different professions and historical context, can help to improve student achievement and functionalization of acquired knowledge, we have conducted a pedagogical experiment with parallel groups of third grade mathematics and science orientation gymnasium students. This innovative approach was used for teaching about carboxylic acids and their derivates. We found that the application of this approach leads to a statistically significant improvement in student achievement and their ability to apply the acquired organic chemistry knowledge in a variety of contexts.Prvi naučni simpozijum sa međunarodnim učešće

Educational value of the history of science content

Osamdesetih godina prošlog veka američki naučni odbor je istakao neraskidivost veze između razvoja nauke i razvoja tehnologije. S obzirom na tehnološki napredak društva u kojem živimo, učenici se u školama moraju osposobljavati za razumevanje tehnoloških inovacija i njihovog uticaja na kvalitet života, kao i za kritičko procenjivanje društvenih pitanja koja obuhvataju posledice razvoja tehnologije [1]. Da bi razumeli nauku i tehnologiju savremenog i budućeg doba, učenici treba da razumeju razvoj nauke i tehnologije u prošlosti. Na primer, kroz odgovarajuće epizode iz istorije prirodnih nauka, učenici mogu sagledati kako tehnologija traži odgovore nauke da bi se razvijala ili, kako se razvijala sposobnost čoveka da uoči problem koji je značajan za istraživanje i čije rešavanje doprinosi razvoju nauke, a samim tim i tehnologije. U ovom radu se govori o potencijalima sadržaja istorije prirodnih nauka za obrazovanje i vaspitanje učenika. Razmatra se uticaj sadržaja iz istorije prirodnih nauka na razumevanje pojmova iz savremenih prirodnih nauka, kao i uticaj na razvoj psiho-fizičkih sposobnosti i formiranje pogleda na svet kod učenika.In the eighties American Scientific Committee noted the connection between the development of science and technology. Because of the technological advancement of modern society, students in schools must be trained to understand the technological innovations and their impact on quality of life, as well as a critical evaluation of the social issues that include the effects of technology development [1]. To understand the science and technology of modern and future times, students need to understand the development of science and technology in the past. For example, through appropriate episodes from the history of science, students can see the relation between technology and science, and their influence on the ability of man to detect a problem that is significant for the study. The impact of the history of science content on student understanding of the concepts of modern science, and development of their skills and view of the world are examined in this paper.Prvi naučni simpozijum sa međunarodnim učešće

Recent landform evolution in Serbia

Serbia can be divided into two major geographical units: the Vojvodina Plain and the southern hills and mountains. In the plain fluvial and aeolian processes and landforms on loess are typical, while south of the Sava and Danube rivers, sheet and gully erosion, mass movements, fluvial, karstic, and fluvio-karstic landform evolution are most influential in shaping the present topography. Among the now inactive geomorphic processes tectonic movements, volcanic activity, coastal, glacial, and aeolian evolution have left behind traces still detectable in modern topography. Some examples of rapid topographic change resulting in the most spectacular landforms (landslides, rockfalls, natural bridges, and rock pinnacles) are presented and described in detail from various regions of Serbia

The algorithm for the assessment of functional work capacity of railway workers with chronic obstructive pulmonary disease (COPD)

The assessment of functional work capacity based on the biological function of the body and a specific job demands and job characteristics, determine whether a person is capable to do the job or group of jobs. Evaluation of work capacity (EWC) railway workers is conducted according to the program of Regulations for the former and periodic examinations of employees in workplaces with high risk published in the Official Gazette of RS no. 120/ 07 and 655. Regulations on health conditions to be met by railway workers, who are directly involved in railway transport. One of the most common chronic diseases during EWC is chronic obstructive pulmonary disease (COPD). The definition of contraindications for use of railway employees with COPD given by Ordinance 655 is in very general terms, trying to make it easier and improve the quality of assessment of work capacity, we have developed an algorithm for the assessment of work ability among these workers. When doubt the existence of COPD should first prove that the disease exists, according to GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines, and for occupational medicine we considered important to clarify and standardize the assessment criteria for EWC, which resulting in a diagnostic algorithm for EWC. It is also important to know which type of job will worker to do. Application of a diagnostic algorithm in EWC will allow optimal assessment of disease severity in railway and other workers suffering of COPD working at the workplace with an increased risk efficacy treatment evaluation; assess compensation of functional defects and determine schedule of periodical examination
