Authors: Lolić Dejan , Kovač Relja , Bajrić Senad , Basara Svetozar
Published: November 2017

Populaciju iz koje je uzet uzorak od 40 ispitanika, čine učenici osnovnih škola, muškog pola, uzrasta 13 i 14 godina ± 6 mjeseci, podjeljenih na grupu od 20 polaznika škole smučanja (eksperimentalna grupa) i grupu od 20 učenika obuhvaćenih samo redovnom nastavom fizičkog vaspitanja (kontrolna grupa). Cilj istraživanja je bio da se utvrde efekti posebno programiranog vježbanja na razvoj agilnosti i fleksibilnosti u okviru škole skijanja kod ispitanika eksperimentalne grupe. Za procjenu motoričkih sposobnosti primjenjeno je 10 testova koji definišu: 1. agilnost ( koverta test, koraci u stranu, osmica sa savijanjem, poligon natraške i okretnost) i 2. fleksibilnost ( pretklon desno, pretklon, zasuk dodir, pretklon raskoračno, duboki pretklon na klupici i čeona špaga). Rezultati multivarijantne analize kovarijanse su pokazali da se ispitanici eksperimentalne grupe statistički značajno razlikuju većim nivoom agilnosti i fleksibilnosti od ispitanika kontrolne grupe.
Selektivna baterija motoričkih testova atletske discipline skok udalj // The Selective Battery of Motor Tests for a Track and Field Event Long Jump

Published: November 2017

Sažetak: Osnovni cilj ove studije je bio identifikacija selektivne baterija motoričkih testova za skok udalj. Na taj način bi se u budućnosti omogućilo trenerima da na jednostavniji način određuju takmičarske potencijale, kao i da preciznije usmjeravaju organizaciju trenažnog procesa.Uzorak ispitanika za ovu studiju je bio sačinjen od 1200 dječaka osnovnih i srednjih škola. Osnovni uzorak je bio podijeljen na osam subuzoraka od po 150 dječaka od petog razreda osnovne škole (11 godina ± 6 mjeseci) do četvrtog razreda srednje škole (18 godina ± 6 mjeseci). Polje motoričkih pokazatelja iz kojeg je trebalo odrediti selektivnu bateriju je bio strukturiran od pokazatelja onih motoričkih sposobnosti, koje su presudne za kvalitetan rezultat u skoku udalj (brzina, eksplozivna snaga gornjih ekstremiteta, eksplozivna snaga donjih ekstremiteta i gipkost).Ovim istraživanjem je utvrđeno da najveći nivo selektivnog kvaliteta imaju testovi za procjenu eksplozivne snage donjih ekstremiteta horizontalnog tipa: skok uvis s mjesta i troskok s mjesta, testovi za procjenu brzine trčanja: trčanje 20 metara leteći start i trčanje 30 metara visoki start, kao i test za procjenu eksplozivne snage gornjih ekstremiteta, bacanje medicinke iz ležanja. To su testovi koji se moraju naći u svakoj bateriji testova, koja za cilj ima selekciju mladih atletičara za skok udalj.

Published: November 2017

Apstrakt: Uvođenjem inkluzivnog modela obrazovanja u Republici Srbiji, školske 2010/11. godine, u središtu stručnog i naučnog interesovanja našli su se nastavnici kao neposredni realizatori inkluzivne nastave. S obzirom da stavovi nastavnika prema inkluzivnoj nastavi fizičkog vaspitanja predstavljaju jedan od ključnih faktora efektivnosti inkluzivne nastave, kao i da 70% teritorije Srbije čine ruralne regije, sprovedeno je istraživanje sa ciljem da se ispitaju razlike u stavovima prema inkluzivnom fizičkom vaspitanju učitelja seoskih i gradskih škola. Na uzorku od ukupno 84 učitelja (80 žena, 4 muškarca) primenjen je upitnik ATIPE (Hutzler, Zach, & Gafni, 2005) za procenu stavova prema inkluzivnom fizičkom vaspitanju. Dobijeni rezultati pokazuju da učitelji iz seoske i gradske sredine imaju slična obeležja socio-profesionalnog statusa. Učitelji naginju umereno pozitivnim stavovima prema inkluzivnom fizičkom vaspitanju. Razlike između subuzoraka su na granici značajnosti (p = .06), pri čemu su u proseku nešto pozitivnije stavove iskazali seoski učitelji.
Социолошки приступ и научно посредовање у спорту // Sociological Approach and Scientific Mediation in Sports
Authors: Коковић Драган , Латиновић Борис
Published: November 2017

Резиме: Са социолошког становишта, поготово у ситуацијама кад се живот повлачи на све ужи понтон око кога хуманист треба да се бори у „води до кољена“, идеја да се наука и на подручју спорта примијени у хуманитарне сврхе добија све више присталица. Наглашавању овакве оријентације допринијело је сазнање и околност да је наука доведена у ситуацију да недостојно служи туђем користољубљу, да се претвара у средство против хуманитета и вриједности и да се све више преобраћа у увјежбаност, некритичну послушност и институционалну моћ. У односу на раније, традиционално схватање спорта, чини се да је потребно рећи шта се подразумјева под савременим спортом. У питању је један еластични епитет који више говори о ономе ко га употребљава, него о појави о којој је ријеч. Зато би увијек требало разграничити о којој врсти спорта се говори, шта се подразумијева под спортом итд. Социлогија у својим анализама узима у обзир ове специфичности покушавајући да одговори на питања зашто је спорт тако популаран. Као начин призводње друштвеног живота, спорт производи побједнике и поражене, а све то произлази из репродукције супарништва и такмичарског духа. Он поприма одређене садржаје, карактер, правце и вриједности у зависности од конкретно историјских услова, структуре друштва у чијим се оквирима развија. Спортска такмичења, на различите начине, изражавају вриједности и односе који реално постоје у друштву и међу људима.
Razlike u posedima lopte, kontaktima sa loptom i kontakt indeksima osvajača medalja na svetskom fudbalskom prvenstvu 2010. godine // Differances in Ball Possessions, Contacts With the Ball and Contact Index of the Medal Winners on the World Championship 2

Sažetak: Istraživačka pažnja je usmerena na evidentiranje poseda lopte, kontakata sa loptom i kontakt indeksa u igri osvajača medalja na Svetskom fudbalskom prvenstvu 2010. godine. Očekuje se s obzirom na plasman reprezentacija da nema statistički značajne razlike u posmatranim karakteristikama fudbalske igre. Posmatrana je ukupno 21 utakmica. Na osnovu rezultata dobijenih statističkom obradom prikupljenih podataka primenom Kruskall Wallis testa može se zaključiti da postoje statistički značajne razlike u zastupljenosti poseda lopte (p=0,005) i kontakata sa loptom (p=0,005), a da kod kontakt indeksa (p=0,129 ) nisu utvrđene statistički značajne razlike u igri posmatranih reprezentacija. Testiranjem razlika između parova reprezentacija Mann Whitny testom utvrđeno je da između reprezentacija Španije i Holandije postoji statistički značajna razlika u sve tri varijable (p<0.05), a između reprezentacija Holandije i Nemačke nisu utvrđene statistički značajne razlike (p>0,05). Između reprezentacija Španije i Nemačke utvrđene su statistički značajne razlike u posedima lopte i kontaktima sa loptom, a kod kontakt indeksa nije utvrđena statistički značajna razlika.
Upravljanje zdravstvenim rizicima od mikrobioloških opasnosti pri korištenju voda bazena za kupanje i rekreaciju // The Management of Health Risks From Microbiological Dangers While Using Swimming Pool Water for Swimming and Recreation
Authors: Antonić Bogoljub , Mihajlović Branislav , Antonić Darijana
Published: November 2017

Sažetak: Potreba za rekreacijom kao jednim od načina održavanja psihofizičkog zdravlja i radne sposobnosti, je bitna potreba savremanog čovjeka. Značajan broj ljudi, povremeno ili stalno, koristi u te svrhe bazene. Međutim, rekreativne aktivnosti na bazenima, ali i korištenje bazena u svrhu liječenja ili oporavka, mogu da ugroze zdravlje, tako da je neophodno odgovarajuće upravljanje bazenima kako bi se taj uticaj sveo na što manju mjeru.Korisnici bazena izloženi su različitim opasnostima od kojih je rizik obolijevanja prouzrokovan mikrobiološkom kontaminacijom vode bazena najveći. Rizik bolesti ili infekcija zbog korištenja bazena povezan je, u prvom redu, sa fekalnom kontaminacijom vode zbog fecesa kupača ili fekalnom kontaminacijom vode sa kojom se puni bazen. Patogeni mikroorganizmi predstavljaju najčešći i najrašireniji zdravstveni rizik vezan za vodu kao sredinu zbog pojava infektivnih bolesti izazvanih bakterijama, virusima i parazitskim protozoama. Prećišćavanje vode smanjuje dijelom taj rizik, ali se najveća mjera sigurnosti korisnika može ostvariti tek dezinfekcijom vode u bazenu. Kulatura i samodisciplina kupača su doprinosni činioci njenoj bezbijednosti.Razmatranje problema upravljanja mikrobiološkim kvalitetom vode u bazenima, izloženo u ovom radu, bazira se najvećim dijelom na odgovarajućim Preporukama Svjetske zdravstvene organizacije (WHO, 2000).

Authors: Đokić Zoran , Idrizović Kemal , Dulić Slaven , Levajac Dragomir
Published: November 2017

Istraživanje sa ciljem procene vannastavne fizičke aktivnosti i fizičke forme sprovedeno je na uzorku od 333 učenika starijeg školskog uzrasta. Analize su sprovedene prema polu, školskom urastu i vannastavnoj fizičkoj aktivnosti. Učenici i učenice petih razreda su najmanje uključeni u vannastavnu fizičku aktivnost. Učenici su aktivniji u odnosu na učenice. Kod učenika i učenica koji nisu fizički aktivni vrednosti indeksa telesne mase su povišene (gojaznost kod fizički neaktivnih učenika je 5.2 – 6.2%, kod učenica 3.4 – 6.7%, dok je kod fizički aktivnih učenika 1.2-1.4%, i učenica 0.7-2.1%). Kod učenica, u svim analiziranim grupama zabeležena je gojaznost. Osim kod učenica petog razreda, između svih ostalih grupa ispitanika, zabeležena je statistički značajna razlika u odnosu na vrednosti kardirespiratorne forme, u korist ispitanika koji su imali vannastavnu fizičku aktivnost. Kardiorespiratorna forma je uglavnom ispod nivoa dobrih u odnosu na optimalne kriterijume.
Matrična forma kompromisne optimizacije funkcionalne ishrane // Matrix Form of Compromising Optimization of Functional Nutrition
Authors: Landika Mirjana
Published: November 2017

Funkcija ishrane ljudskog organizama jeste da se obezbijede hranljivi sastojci potrebni za njegovo optimalno funkcionisanje. Poznato je da se zahtjevi ishrane razlikuju prema zdravstvenom stanju, fizičkoj kostituciji, starosti, polu, psihofizičkom opterećenju i drugim internim i eksternim faktorima svakog pojedinca.Moderan način života karakterišu, pored ostalog, nekvalitetna, neredovna ishrana u kombinaciji sa intenzivnim psihičko – psihološkim opterećenjima, pretežno „sjedelački“ životni stil, nedovoljno kretanje i izostanak boravka u prirodi. Takav stil života intenzivno korelira sa brojnim zdravstvenim problemima, pri čemu se brojni mogu prevenirati, pa i „liječiti“ formulacijom adekvatne ishrane, čija struktura i kvalitet podižu funkcionalnu potentnost ljudskog organizma kao složenog sistema .Jedna od osnovnih karakteristika sistema sastoji se u tome da se promjene na jednom elementu direktno ili posredno reflektuju na sisitem kao cjelinu. Brojni su pokušaji da se „propišu“ adekvatni programi ishrane, koji u velikom broju uzrokuju rezistenciju korisnika, jer se odnose na ograničavanje, izbacivanje pojedinih namirnica, zatim nemogućnost ili nepristupačnost propisanih komponenti jelovnika, neadaptivnost i nefleksibilnost programiranih režima ishrane. Ishrana ljudskih organizama, kao složenih sistema, treba da omogući odgovarajući kvalitet koji se iskazuje i mjeri sadržajem ugljikohidrata, masnoća, proteina, vode, vitamina i minerala sa jedne strane, sa potrebama, mogućnostima, dostupnošću pojedinih namirnica, platežnom moći i ličnim preferencijama individualnih korisnika sa druge strane. Podizanje stepena fleksibilnosti, adaptivnosti, dostupnosti programa ishrane usklađene sa individualnim zahtjevima i potrebama različitih korisnika uz očuvanje potrebne visine kvaliteta i kvantiteta iste, moguće je postići i održavati korištenjem optimizacionih modela iz sfere kompromisnog programiranja.
Korisnička percepcija sistema sportskih usluga karate kluba // Users’ Perception of a Sports Service System in a Karate Club
Authors: Nešić Milan , Dačić Dušan , Srdić Velibor
Published: November 2017

Karate klub kao sportska organizacija konstitutivno je definisana kao specifičan organizacioni sistem koji ima svoju odgovarajuću strukturu, koja se, u prvom redu, odnosi na fizičke elemente i informacione veze. U praksi strukturu većine karate klubova uglavnom karakteriše postojanje dva segmenta - organizacioni blokovi i operativne aktivnosti. Operativne aktivnosti su najodgovornije za realizaciju postavljenih ciljeva, jer se kroz njih vrši protok ljudi - korisnika usluga i ljudskih resursa organizacije. S obzirom da danas karate klubovi u najvećem broju egzistiraju kao udruženja (neprofitne organizacije), na njih se sasvim aplikativno odnosi teorijsko stanovište da uspeh neprofitnih organizacija upravo zavisi od činjenice koliko efektivno i efikasno zadovoljavaju potrebe svojih korisnika. Odnosno, u kojoj meri raspolažu organizacionim kapacitetima koji su u stanju da „sportskom tržištu“ isporuče efektivnu uslugu.Takođe, kompleksnost ciljeva karate kluba kao neprofitne sportske organizacije imanentna je i složenom individualnom doživljaju konzumenta usluge u celini, čime se profiliše pažnja davaoca usluge ka zadovoljstvu korisnika. Stoga je pitanje adekvatne percepcije relacije „kvalitetna usluga – zadovoljstvo korisnika“ veoma kompleksno, suptilno i delikatno, te često zavisi prevashodno od različitih pogleda korisnika i njihovog shvatanja (poimanja) kvaliteta. Ovo se, svakako, mora uzeti u obzir prilikom različitih aktivnosti evaluacije od strane menadžmenta sportske organizacije. Empirijsko istraživanje koje je realizovano na uzorku od 215 ispitanika korisnika usluga karate kluba „Yu Karate Do“ iz Novog Sada imala je za cilj uvtrđivanje pojedinih činilaca kojima se može vršiti valorizacija rada i kvaliteta usluga koje pruža klub, na osnovu percepcije i zadovoljstva neposrednih korisnika. Dobijeni rezultati su pokazali da korisnici usluga predstavljaju značajnu odrednicu valorizacije njegovog rada, s obzirom da kroz svoje stavove i mišljenja iskazuju vrlo precizne i eksplicitne odrednice o pojedinim činiocima sistema usluga i rada kluba.

Antropološki prostor je vrlo značajan i primaran u selekciji, usmjeravanju i postizanju rezultata u sportu. To se naročito ispoljava u vrhunskom sportu gdje se postižu izuzetni rezultati. Zavisno od sporta, sportske discipline zavisi i učešće i uticaj antropološkog prostora, odnosno njegovih segmenata na ukupan rezultat. Kada se opisuje i definiše određena populacija sportista, njihov morfološki prostor, najčešće se kao parametri analiziraju tjelesna visina, tjelesna masa, bodi mass index, a vrlo često i starosna dob ispitanika. Ovi parametri su vrlo pouzdani i daju realnu sliku o morfološkom prostoru ispitivane populacije. U radu su analizirane razlike u segmentima morfološkog prostora atletičarki skakačica, finalistkinja Olimpijskih igara u Pekingu. Uzorak je obuhvatio 32 takmičarke u četiri discipline (skok u dalj, skok u vis, troskok, skok motkom). Analizirane su razlike u tjelesnoj visini, masi tijela, BMI i starosnoj dobi. Za obradu podataka primjenjen je T-test za male nezavisne uzorke koji je potvrdio postojanje statistički značajnih razlika u tjelesnoj visini atletičarki u disciplinama: skok u dalj - skok u vis (T=-2.906, p<0.05), skok u vis - troskok (T=3,448; p<0.01), skok u vis - skok motkom (T=3,469; p<0.01). Razlike su potvrđene i u vrijednostima BMI u disciplinama: skok u vis-skok u dalj (T=3,496; p<0.01) i skok u vis-troskok (T=-3,136; p<0.01)

Uprkos značajnim teorijskim izvorima koji se odnose na loše držanje kod djece i adolescenata, a koje je izazvala promjena načina života, saznanja o problemu abnormalne kičmene krivine treba da budu dopunjena. Može se uvidjeti sve veći broj gojazne djece i ovaj problem težine može dovesti do veće učestalosti lošeg držanja tijela. Ovaj rad ima za cilj da utvrdi učestalost dobrog i lošeg držanja tijela kod djevojčica u odnosu na njihove tjelesne težine, kao i da otkrije da li prekomjerna težina (gojaznost) daju predispoziciju za loše držanje. Istraživanje je obuhvatilo 500 djevojčica uzrasta 7-15 godina, koje žive u Szczecinu u Poljskoj. U procjeni držanja tjela, korišćena je sferosomatometrijska metoda Ivanovskog. Djevojčice sa normalnom tjelesnom težinom su predstavljale 77,7% ispitanika. U 6,7% slučajeva, identifikovana je nedovoljna tjelesna težina. 11,3% su imale  višak kilograma , dok je 4,3% djevojčica bilo gojazno - što iznosi 15,6 % ispitanica. Nepravilno držanje tijela je identifikovano u 32,4% ispitanica. Najveći broj djevojčica sa lošim držanjem tijela pronađeno je među 9-godišnjakinjama (38,6%), 13-godišnjakinjama (35.2 %) i 15-godišnjakinjama (35,1%). Prekomjerna težina i gojaznost je bila predispozicija kod ispitanica za pojavu nepravilnog držanja kičme: abnormalna kičmena krivina je pronađena u 30,8% gojaznih djevojčica i djevojčica sa prekomjernom težinom.

Cilj istraživanja je da se dokaže djelotvornost programa Kegelovih vježbi na liječenje blage do umjerene stresne urinarne inkontinencije kod žena. Istraživanje je obuhvatilo 43 pacijentice, liječene u konsultativno-specijalističkoj ambulanti Javne zdravstvene ustanove Dom zdravlja Laktaši. Pacijenticama su uzeti: opšti podaci, indeks tjelesne mase, ginekološka anamneza, socijalna anamneza, svim pacijenticama je urađen ginekološki pregled na dan javljanja u konsultativno-specijalističku ambulantu, procijenjen defekt prednje stijenke rodnice prema POP-Q klasifikaciji. Bolji uspjeh u liječenju inkontinencije smo postigli kod žena u pre i perimenopauzi, u odnosu na žene u postmenopauzi. Kod 14 (35%) pacijentica nismo dobili povlačenje tegoba, izazvane inkontinencijom. Takođe, kod 10 (25%) pacijentica koje su rađale krupniju djecu program Kegelovih vježbi nije dao rezultate. Kod 30 (75%) pacijentica koje su imale visoku, višu ili srednju stručnu spremu nakon odrađenih Kegelovih vježbi, smo dobili prestanak inkontinencije. Kod 10 (25%) pacijentica koje su bile domaćice i obavljale teške fizičke poslove nije došlo do oporavka od inkontinencije.Na osnovu dobijenih rezultata, zaključili smo da su Kegelove vježbe efikasan način liječenja blage i srednje teške stres urinarne inkontinencije, ali da na efikasnost utiču brojni faktori, kao što su starosna dob žena, tjelesna težina, obrazovanje, broj poroda, težak fizički rad.

Problem upotrebe zabranjenih supstanci (dopinga) u sportu je bio, jeste i biće aktuelan problem koji narušava sam duh sporta, ljepotu i zadovoljstvo, a vrlo često i zdravlje sportiste. Zbog toga je neophodno pristupiti rješavanju ovoga problema, ako je moguće i trajno, mada je to nekada jednostavno neizvodljivo. U istraživanju je učestvovalo ukupno 200 studenata Fakulteta fizičkog vaspitanja i sporta, od čega 100 studenata Univerziteta u Istočnom Sarajevu (Bosna i Hercegovina) i 100 studenata AMU Aligarh PU (Indija), starosne dobi od 18-26 godina. Od ukupnog uzorka 170 (85%) su bili ispitanici muškog pola, dok je 30 (15%) ženskog pola. Osnovni cilj istraživanja je bio da se provjeri nivo znanja i utvrde stavovi studenata i utvrde njihove međusobne razlike o upotrebi zabranjenih supstanci u sportu. Za prikupljanje neophodnih informacija korišćen je anonimni anketni upitnik sa 13 jasno definisanih pitanja, (11 pitanja zatvorenog i 2 pitanja otvorenog tipa) koja su se odnosila na određena znanja, stavove o dopingu u sportu. Dobijeni su relevantni rezultati koji su globalni pokazatelj informisanosti, znanja i stavova populacije studenata fizičkog vaspitanja i sporta o sve većem problemu današnjeg modernog sporta koga nazivamo doping. Od ukupnog uzorka, čak 85% studenata oba subuzorka su označili atletiku kao sport sa najviše doping afera, a zatim slijedi biciklizam (43%), bodi bilding i dizanje tegova (22%), dok su sportske igre sa (28%), Cricket (25%), Streljaštvo i Šah sa (19%), kao sportovi sa najmanjim brojem doping afera.
Improving Teaching and Learning in Physical Education: Using a Developmental Continuum and Eliminating Traditional Grading / Unapređenje procesa nastave i učenja u fizičkom vaspitanju: Upotreba razvojnog kontinuuma i eliminisanje tradicionalnog ocjenjivanja
Authors: Haug Adrian J , Fischer Mila
Published: November 2017

Assessment methods and the ownership of learning in Physical Education remain, in most cases, as highly traditional practices which do not fully allow students to be active and enthusiastic participants in the process of learning physical skills and health related knowledge. This study focuses on the improvements of student accountability and ownership for learning in Physical Education classes when traditional grading is removed and a year-level-only curriculum is replaced with a developmental learning continuum. The context of this study is to identify the relationship between student motivation, interest in learning, and the accountability to reach set goals when grade rewards are replaced with clear descriptions of student performance and development along a schema of skills and knowledge in PE. The research of our project will determine that the modifications made to the process of teaching and learning has improved the learning experience of our test subjects. The study has proven that when traditional grading is removed and students have the opportunity for true differentiated learning, they demonstrate far more intrinsic motivation in their learning. The students have taken grater ownership over their development and have become more accountable for their own process of learning. To truly unlock the potential of each child, we educators need to support our students to be risk takers who are inquiring and reflective.
Relacije motoričkih sposobnosti i tehničko-taktičkih karakteristika stolnotenisača / Relations Between Motor Abilities and Technical and Tactical Characteristics of Table Tennis Players

This study was conducted with aim to determine the relations between motor skills and technical and tactical characteristics of table tennis players. The study was conducted on a sample of 48 of the best seniors with aged 18-36 years old (a representative sample) in Bosnia and Herzegovina. For this purpose was applied the system of (12) variables to estimate the basic motor skills, and (8) variables for evaluation of technical and tactical characteristics of table tennis players. In order to determine the relations between the basic motor skills and technical and tactical characteristics of table tennis players, the method applied was the method of canonical correlation analysis. Establishing the link between these two areas resulted in the separation of one canonical factor which was statistically significant. The most significant information for extracted canonical component gives the coefficients of the structure and the cross-structure. The coefficients of the structure represent the correlations of the original variables with canonical component derived from a set of variables to which this variable originally belongs, while coefficients of cross- structure provide correlations of adequate source variables with canonical component that was created in other set of variables. Onto the isolated canonical function the most significant influence have the variables of hand tapping, throwing a medicine 1kg ball by forehand, boom in gray, long jump from the place, while also slightly smaller significance show other variables, but from the same subspaces of basic motor abilities. Based on the coefficients of the structure can be summarized that all the technical and tactical characteristics highly correlate with the factor isolated from this area which is logical, because all manifest variables represent one area (technical skills / playing skill). The variables that are related to the attack phase (initiative in points) and elements of game movement (the safety and effectiveness of the attack over the table, safety and efficacy of the first entrance, efficiency of game movement) are significantly associated with canonical factor isolated in the area of motor abilities. These variables describe technical structures in which “imposes” and maintains the initiative in the point, and are the most aggressive attack techniques, and generally seek the largest motor engagement. No surprises then that exactly these variables of technical and tactical structures are significantly associated with the factor isolated in the area of motor abilities are the most important.

The research includes participants of masculine and feminine genders, between 12 and 13 years of age that belong to the category of young juniors according to the categorisation of the Bosnia and Herzegovina Dance Association. The research validated metric characteristics of tests for assessment of coordination skills of the whole body and specific coordination skills in rhythm.The main objective of the research was to determine metric characteristics of measuring instruments (tests) for assessment of coordination skills of young juniors in dance.Based on the calculated metric characteristics of measuring instruments (tests) for assessment of coordination skills, it can be stated that almost all the tests assessing coordination skills have very good metric characteristics, because reliability coefficients are quite high and they range from 0.93 to 0.99. Given the high-quality structures of correlation matrices of items and their projection on the first principal component, it can be stated that all items of each measurement belong to one manifesting common space which indicates that the tests measured what they were intended to measure. Based on the results obtained in this research, the recommendation is to use the applied tests for the purposes of diagnosing coordination skills in dance, as well as for programming the training process of dancers.

Research was conducted on a sample of 121 respondents in total-sportsmen aged 14-16 years old from five different sports (skiing, boxing, swimming, volleyball and basketball), trough a questionnaire containing 19 representative indicators – qualities that the coach should possess. Examined are the attitudes of young and promising sportsmen of the desirable characteristics of a good coach. It’s about the selected young and promising sportsmen, whose quality is determined on the basis of achieved results at official championships in of Republic of Srpska, Bosnia and Herzegovina and international competitions. The survey questionnaire was administered in which any claim has 5 replies as follows: always, often, sometimes, rarely did I ever. It’s about five-point Liker scale. The survey contains questions related to gender, length of training period and type of sport. In order to determine the latent structure of the appropriateness of indicators was used factor analysis with Varimax rotation in solution. Given results of the factor analysis with Varimax rotation in solutions showed stable set of four isolated latent dimensions that can be described as: (1) technical quality of the trainers (2) the general human traits coaches (3) external characteristics of trainers and (4) the ratio of coaches to the sportsmen. The results point to the fact that the qualities that a coach has to exhibit the work of young and promising sportsmen in training and competition is of great importance for the formation of the whole personality and versatile young sportsmen in his sport promotion.

The research was aimed at determining the changes in functional abilities of women under the influence of recreational swimming. The sampled population consisted of healthy women, aged 35 to 45, chronologically, with a dominant sedentary lifestyle. The assessment of functional ability was tested using the following variables: vital capacity, heart rate at rest, working heart rate, systolic blood pressure, diastolic blood pressure and relative oxygen consumption. Basic parameters of descriptive statistics were calculated for all the results, whereas the T-test was applied to determine the difference between the initial and final measurement. The results of the research showed that there were statistically significant changes of vital capacity after three months of recreational swimming (p = 0.000), heart rate at rest (p = 0.000) and relative oxygen consumption (p = 0.000). The research found that the programme of recreational swimming with sedentary middle-aged women can act effectively to change functional abilities.

Man is by living in urban areas, exposed to a variety of factors that directly or indirectly affect its health, living conditions and the only life. People feel a lack of spatial freedom, a growing number of nervousness, depression, accidents in traffic, deformities, degenerative diseases, etc.. To prevent all this, one must increasingly move because certain physical activities increase the functional capability of all organ systems. Swimming is a physical activity that is at the effectiveness of the head, and a significant number of people, temporarily or permanently, to use swimming pools. Recreational activities at the pools could endanger health, so it is necessary to the proper management of the pools, to the negative impact of reduced to the smallest possible measure. Tests confirmed that the quality of the water depends on the proper disciplinary proceeding purification and disinfection of water, depending on the workload of the pool, the implementation of appropriate sanitary-hygienic measures and user behavior as a contributory factor to water pollution.

The Electromagnetic Considerations of the Nuclear Force
Authors: Bowen N L
Published: November 2017

This paper explores how the electromagnetic energies of the quarks within the nucleus affect the behavior of the nuclear force. By examining the electromagnetic energies and forces, many questions about nuclear behavior can be answered and many insights into the nucleus can be gained. Previous theoretical models for the nuclear force include only the Coulomb electric forces, but with a disregard of the electromagnetic characteristics of the quarks. By incorporating the electromagnetic energies and forces into nuclear theory, this model has been able to achieve predictions of binding energy better than any previous model, doing so by using only one variable instead of five. This model also directly unifies the nuclear force to the electromagnetic force.

In industry, the yeast Rhodotorula mucilaginosa is commonly used for the production of carotenoids. The production of carotenoids is important because they are used as natural colorants in food and some carotenoids are precursors of retinol (vitamin A). However, the identification and molecular characterization of the carotenoid pathway/s in species belonging to the genus Rhodotorula is scarce due to the lack of genomic information thus potentially impeding effective metabolic engineering of these yeast strains for improved carotenoid production. In this study, we report the isolation, identification, characterization and the whole nuclear genome and mitogenome sequence of the endophyte R. mucilaginosa RIT389 isolated from Distemonanthus benthamianus, a plant known for its anti-fungal and antibacterial properties and commonly used as chewing sticks. The assembled genome of R. mucilaginosa RIT389 is 19 Mbp in length with an estimated genomic heterozygosity of 9.29%. Whole genome phylogeny supports the species designation of strain RIT389 within the genus in addition to supporting the monophyly of the currently sequenced Rhodotorula species. Further, we report for the first time, the recovery of the complete mitochondrial genome of R. mucilaginosa using the genome skimming approach. The assembled mitogenome is at least 7,000 bases larger than that of Rhodotorula taiwanensis which is largely attributed to the presence of large intronic regions containing open reading frames coding for homing endonuclease from the LAGLIDADG and GIY-YIG families. Furthermore, genomic regions containing the key genes for carotenoid production were identified in R. mucilaginosa RIT389, revealing differences in gene synteny that may play a role in the regulation of the biotechnologically important carotenoid synthesis pathways in yeasts.

The presence of acetic acid during industrial alcohol fermentation reduces the yield of fermentation by imposing additional stress on the yeast cells. The biology of cellular responses to stress has been a subject of vigorous investigations. Although much has been learned, details of some of these responses remain poorly understood. Members of heat shock chaperone HSP proteins have been linked to acetic acid and heat shock stress responses in yeast. Both acetic acid and heat shock have been identified to trigger different cellular responses including reduction of global protein synthesis and induction of programmed cell death. Yeast HSC82 and HSP82 code for two important heat shock proteins that together account for 1–2% of total cellular proteins. Both proteins have been linked to responses to acetic acid and heat shock. In contrast to the overall rate of protein synthesis which is reduced, the expression of HSC82 and HSP82 is induced in response to acetic acid stress. In the current study we identified two yeast genes DOM34 and RPL36A that are linked to acetic acid and heat shock sensitivity. We investigated the influence of these genes on the expression of HSP proteins. Our observations suggest that Dom34 and RPL36A influence translation in a CAP-independent manner.

The At Home / Chez Soi demonstration project was conducted to investigate the effectiveness of the Housing First model in 5 Canadian cities. Using a randomized controlled trial design, this study evaluates the impact of this project on the use of health services by people with severe and persistent mental health problems and a history of homelessness in the greater Moncton area. The sample comprised 193 homeless persons, 95 in the control group and 98 in the treatment group. The results show a significant difference between the 2 groups only in the number of days of hospitalization, particularly in the psychiatric unit. Factors associated with the use of health services by people who are homeless and who have severe mental health problems need to be further investigated.
The Defining Characteristics of ENSO Extremes and the Strong 2015/2016 El Niño
Authors: Santoso Agus , Mcphaden Michael J. , Cai Wenju
Published: November 2017

The year 2015 was special for climate scientists, particularly for the El Niño Southern Oscillation (ENSO) research community, as a major El Niño finally materialized after a long pause since the 1997/1998 extreme El Niño. It was scientifically exciting since, due to the short observational record, our knowledge of an extreme El Niño has been based only on the 1982/1983 and 1997/1998 events. The 2015/2016 El Niño was marked by many environmental disasters that are consistent with what is expected for an extreme El Niño. Considering the dramatic impacts of extreme El Niño, and the risk of a potential increase in frequency of ENSO extremes under greenhouse warming, it is timely to evaluate how the recent event fits into our understanding of ENSO extremes. Here we provide a review of ENSO, its nature and dynamics, and through analysis of various observed key variables, we outline the processes that characterize its extremes. The 2015/2016 El Niño brings a useful perspective into the state of understanding of these events and highlights areas for future research. While the 2015/2016 El Niño is characteristically distinct from the 1982/1983 and 1997/1998 events, it still can be considered as the first extreme El Niño of the 21st century. Its extremity can be attributed in part to unusually warm condition in 2014 and to long‐term background warming. In effect, this study provides a list of physically meaningful indices that are straightforward to compute for identifying and tracking extreme ENSO events in observations and climate models.

Published: November 2017

A facile and efficient approach has been developed for the synthesis of carbazoles from 2‐iodobiphenyls and diaziridinone under palladium catalysis. A wide range of carbazoles were synthesized in good to excellent yields, and indole derivatives were obtained by using styrenes as the substrate. The palladacycles obtained from 2‐iodobiphenyls acted as the key intermediate, and the reaction should proceed via a tandem Pd‐catalyzed C−H activation/dual C−N bond formation sequence.

A deuterium‐labeling reaction of nitroalkanes in deuterium oxide and the subsequent nitroaldol reaction have been accomplished under basic and organocatalytic conditions to provide the deuterium‐labeled β‐nitroalcohols in high yields and high deuterium contents. β‐Deuterated β‐nitroalcohols could be smoothly obtained from the reaction of nitroalkanes and various electrophiles using the easily‐removal basic resin WA30. Furthermore, the asymmetric nitroaldol reaction using nitromethane and α‐keto esters as electrophiles in the presence of a quinine‐derived organocatalyst in deuterium oxide could provide the desired β‐deuterated nitroalcohol derivatives with high enantioselectivities.

Published: November 2017

The aim of this work was to reduce/minimize Li in Li‐LSX by replacing the 70% Li+ cations in Li‐LSX that are bonded to the interior or inaccessible sites which are not used for adsorption. Thus, mixed‐cation LiCa‐LSX containing minimum lithium were prepared by exchanging small fractions of Li+ into Ca‐LSX, followed by dehydration under mild conditions to avoid migration/equilibration of Li cations. Comparisons of adsorption isotherms of N2/O2 and heats of adsorption for the LiCa‐LSX samples with that for pure‐cation Li‐LSX and Ca‐LSX provided strong evidence that significant amounts of these Li cations indeed remained on the exposed sites (SIII). The mixed‐cation LiCa‐LSX samples were compared against the pure‐cation Ca‐LSX and Li‐LSX based on their performance for oxygen production by PSA, via model simulation. The results showed that the mixed‐cation LiCa‐LSX samples yielded significantly higher O2 product productivities at the same product purity and recovery than their pure‐cation precursor (Ca‐LSX). © 2017 American Institute of Chemical Engineers AIChE J, 64: 406–415, 2018

Authors: Hikawa Hidemasa , Ichinose Risa , Kikkawa Shoko , Azumaya Isao
Published: November 2017

An “on water” synthetic strategy for the selective construction of 2‐arylbenzimidazoles involving the dehydrogenation of benzyl alcohols by a π‐benzylpalladium(II) system has been developed. This simple oxidant‐ and base‐free protocol can be achieved under mild conditions in an atom‐economic process from o‐phenylenediamines and benzyl alcohols, affording the desired products in moderate to excellent yields. Notably, the “on water” protocol is essential for achieving this new synthetic method in our catalytic system.

Background

The measurement of nasal specific IgE (NsIgE) in local allergic rhinitis (LAR) patients is challenging and shows variability. The objective of this work was to evaluate a minimally‐invasive method of direct detection of NsIgE in patients with LAR to Dermatophagoides pteronyssinus (DP) using an automated immunoassay.

Methods

Fifty patients participated (LAR, n = 14; allergic rhinitis (AR), n = 20; healthy controls [HC], n = 16). Detection of NsIgE was performed by direct application of the solid phase of a commercial DP ImmunoCAP® test 24 hours after DP nasal provocation.

Results

There was no difference in the median volume of secretion absorbed by the solid phase of the ImmunoCAP test in the 3 studied groups (p = 0.17). According to receiver operating characteristic (ROC) curve analysis, NsIgE ≥0.1450 was the optimal cutoff point, obtaining in LAR patients 42.86% sensitivity with the highest specificity (100%), and 75% sensitivity and 100% specificity for AR.

Conclusion

This study demonstrates the detection of NsIgE to DP in LAR by using a simple, commercial device with high specificity.
Characteristic Attributes of Multiple Cascaded Terahertz Metasurfaces with Magnetically Tunable Subwavelength Resonators
Authors: Serebryannikov Andriy E. , Lakhtakia Akhlesh , Ozbay Ekmel
Published: November 2017

The characteristics of multiple cascaded metasurfaces comprising H‐shaped, magnetostatically controllable, subwavelength terahertz (THz) resonators made of InAs were systematically investigated, using a commercial solver based on the finite‐integration method, for the design of tunable filters. Three configurations of the biasing magnetostatic field were compared with each other as well as with the bias‐free configuration for filtering of normally incident linearly polarized plane waves. A close study of only one metasurface was found sufficient to broadly determine the sensitivity to the direction of the magnetostatic field and the bandwidth of a stopband. Furthermore, the effects of metasurface geometry and biasing field can be considered separately for initial design purposes. All features in the transmittance spectra for the bias‐free configuration that are related to the number of cascaded metasurfaces are also observed when the biasing magnetostatic field is applied. The coupling of adjacent metasurfaces in a cascade is strongly affected by the relative permittivity and the thickness of the spacer between the two metasurfaces. The spectral locations of stopbands scale with respect to the spacer's relative permittivity, the scaling rule being different from a classical one. The stopbands are redshifted when the spacer thickness is increased, with the redshift dependent on the polarization of the incident plane wave. Inter‐metasurface coupling and inter‐resonator coupling on the same metasurface affect the spectral location of a stopband in opposite ways. On‐off type switching can be obtained by changing the orientation of magnetostatic field. The elucidated characteristics are expected to be important for not only filters but also other tunable THz devices.
