The concept of proper nutrition implies meeting the needs of the body concerning daily energy intake and a sufficient amount of nutrients and protective substances necessary to maintain the physiological functions of the body and its health. Nutrients are divided into macronutrients (proteins, carbohydrates and fats) and micronutrients (vitamins and minerals). Accelerated growth and development during adolescence increase nutrient requirements. Therefore, energy and nutrition requirements must meet the needs of adolescents. During their growth and development, there is an increased need for vitamins and minerals, especially for calcium, iron, zinc and vitamin D. During intensive growth, adolescents require more vitamins, especially B-complex vitamins and vitamin C, the intake of calcium and phosphorus is necessary as well, and the insufficient needs for proteins affect the development of muscles and energy levels. Proper nutrition and eating habits during the period of growth are of the utmost importance for the appropriate physical, psychosocial and cognitive growth and development of a child. Eating disorders usually occur as a result of low or high energy intake, and the most common types of these disorders are anemia, anorexia and bulimia, obesity and comorbidities, and poor eating habits. When it comes to the implementation of various programs concerning the prevention of bad eating habits and eating disorders, the school management, expert teams and student parents should bear the overall responsibility. Once or twice a year, preventive check-ups and BMI measurements are recommended to identify eating disorders.

Introduction. The aim of the study was to examine the correlation between subjective well-being and quality of life of the elderly in relation to their demographic characteristics, health, social and financial status. Methods. The study sample was comprised of 159 subjects of both sexes and of older age. The respondents underwent research in Banja Luka in the premises of the Association of Pensioners of the Republic of Srpska, senior citizens' clubs when coming to some of financial institutions to get help, to open bank accounts etc., as well as in the premises where pensioners gather to socialize and communicate. The survey questionnaire developed for the purpose of the paper and adapted to this population was used in the study. The survey questionnaire consisted of the following elements: sociodemographic data, self-assessment concerning the quality of life and Quality of Life Scale for the Elderly. Results. The study included a total of 159 subjects, 56.6% males and 43.4% females, of whom the majority were 65-75 years old (67.3%). The average health status (M = 2.17; SD = 0.68) was higher than the expected value, while the social status (M = 1.93; SD = 0.60) and the social needs (M = 1.91; SD = 0.72) were slightly lower compared to theoretical mean. Furthermore, the financial status had an average value (M = 2.08; SD = 0.59). The distribution of social needs was unsatisfactory. The obtained value of the Self-Perceived Quality of Life Scale was within the range of the theoretical mean values (M = 5.54, SD = 2.47), indicating that the distribution of the obtained quality of life values was symmetrical. Conclusion. Financial status significantly affects the quality of life of the elderly. The distribution of social needs is unsatisfactory. The level of education significantly affects the quality of life: highly educated respondents have a better health, social and financial status compared to the elderly with a lower level of education.

The working class was, at least formally, a formative basis of the former Socialist Federative Republic of Yugoslavia (SFRY). The transformation of the system from the Communist to the capitalistic one led to its alienation, poverty, and social exclusion. This transformation, as part of the neoliberal globalisation, occurred through the introduction of the so-called 'shock therapy' measures: liberalisation, privatisation, and stabilisation. Large industrial complexes and leading stateowned companies in the SFRY were the subject of, often dubious, privatisation processes. Through such processes, workers, who were once owners and motors of companies they worked at, are now stripped of the ownership and the opportunity to work at the same companies. The majority of research on postCommunist economic transformation focuses on changes to the system, on economic aspects of privatisation processes, and on introduction of market economy. Yet, there are few research focusing on the privatisation and transformation from a workers' perspective. This paper attempts to fill in this gap by providing a different angle to the current studies of transformation of the SFRY and its successor states. Through interviews with former workers of privatised and/or closed factories and industrial complexes (using the local company of 'Rudi Čajavec' as an example), the research presented in this paper analyses workers' attitudes and sentiments towards the labour in the Communist Yugoslavia and the labour today, as well as towards the privatisation processes accompanying the latter.The research gives a voice to the workers, and, by looking at the past, gives a worker-centred approach to imagining labour in the future.

Social transformation and transition from socialist to liberal market economy in Bosnia and Herzegovina and other countries of former Yugoslavia, followed by war atrocities, initiated a series of economic and social challenges: deindustrialization, high unemployment, dubious privatizations, impoverishment, ethnic rivalries and structural changes. In this paper, we observe the mentioned social processes focusing on identity politics resulting in transformation of class identity into workers' national identity. The main presumption is that certain critical social moments serve as a trigger for "shift" in primacy of class compared to national identity and vice versa. To address this, we are using cases of workers' resistance/strikes/ protests during the social transformation from socialist into market economy, and after the completed privatization and reign of ethno-national policies in former Yugoslavia countries.

The environmental benefits of green roofs have been widely recognized. In recent years, increasing attention has been paid to moisture management in the green roof systems. The moisture in the green roof has an influence on its thermal and hydrological performances. An accurate measurement of water content in green roof substrate is important for irrigation monitoring, optimal irrigation management, and plant growth. Knowing the performance and characteristics of the sensor for the chosen substrate layer in a green roof system is essential. This paper presents laboratory calibration of the capacitive moisture sensor in two types of the green roof substrate layer. The volumetric water content of several mineral wool and soil samples, with the water content from low until saturated, were measured using the gravimetric method and related to frequency obtained by the sensor. The results have shown that the capacitive moisture sensor has a good response to water content variation.

Poremećaji hoda i poremećaji ravnoteže uobičajeni su klinički problemi za starije osobe. Uzroci poremećaja hoda su individualni, često zbog fiziološkog procesa starenja i somatskih bolesti. Poremećaji hoda dovode do gubitka lične slobode, pada i povreda i rezultiraju značajnim smanjenjem kvaliteta života. Kod starijih osoba, kontrola statičke i dinamičke kontrole položaja i ritma je poremećena, što dovodi do izmijenjenog hoda, smanjuje se korak, povećava se širina hoda kako bi se održala ravnoteža, gornji dio tijela se savija prema naprijed da bi se održala ravnoteža, ruke se ne pomiču dok hodaju, hod je nepravilan, teže je započeti prve korake nakon sjedenja ili stajanja, kao i okretanja. Ako je moguće, najbolje je tretirati etiološki faktor, tj. osnovne bolesti, kao što su parkinsonizam, neki metabolički poremećaji itd. Treba voditi računa o nusefektima nekih lijekova, naročito antiparkinsonika, sedativa, hipnotika i antidepresiva. Također je potrebno uključiti i druge specijaliste, kao što su reumatolozi, fizijatri i fizioterapeuti, kao i internisti, kardiolozi i dijabetolozi. Kognitivne strategije također mogu biti korisne, na primjer usmjeravanje pažnje na svaki pojedinačni korak, a ne čin hodanja kao takav, svjesno pokušavajući napraviti pojedinačne velike korake, ili mentalno brojanje, kao i upotreba pomagala za hodanje.

SAŽETAK: Uvod: Alergija na hranu je u zadnjih 20 godina postala značajan zdravstveni problem. Prevalencija se kreće od 3-38% samoprijavljenih slučajeva, odnosno od 1-7% dijagnosticiranih slučajeva alergije. Zadnjih godina su poduzeti brojni projekti kako bi se odredila prevalencija, vrsta alergena, uzroci alergija, veza sa ostalim zdravstvenim problemima, načini dijagnosticiranja, provođenje kontrole rizika u prehrambenoj industriji, prilagođavanje zakonske regulative potrebama alergičnih osoba itd. Dok su neke države uradile mnogo po ovom pitanju, još uvijek je veliki broj onih koji nemaju podataka o alergijama na hranu na svom području, a takva je situacija i u BiH. Cilj rada: Utvrditi prevalenciju alergija na hranu iz anketnog ispitivanja u Kantonu Sarajevo. Utvrditi kakva je učestalost nekih drugih alergija kod ispitanika. Materijal i metod rada: Ovo presječno istraživanje o alergiji na hranu provedeno je tokom marta i aprila 2017. među stanovnicima Kantona Sarajevo oba spola i svih dobnih skupina metodom slučajnog uzorka. Posebno dizajniran anketni upitnik od 16 pitanja popunilo je 480 ispitanika. Istraživanje je provedeno retrospektivno. Rezultati: Rezultati ankete provedene na području Kantona Sarajevo pokazuju procenat od 51% osoba koje prijavljuju da imaju neku vrstu alergije, među njima je 20% prijavljenih alergija na hranu, odnosno 11,7 % slučajeva dijagnosticiranih alergija na hranu, a u odnosu na ukupan broj od 480 (100%) ispitanika koji su učestvovali u anketi. Najčešće prijavljeni alergeni su: mlijeko i mliječni proizvodi, žitarice, jaja, kikiriki, orašasti plodovi, riba (sa školjkama i rakovima) i jaja. Zaključak: Dobiveni rezultat prevalencije alergije na hranu u našem istraživanju u ukupnom ispitanom uzorku od 480 anketiranih, njih je 96 (20%) ispitanika što ukazuje da je problem alergija na području Kantona Sarajevo značajan, i da se učestalost kreće u vrijednostima koje su karakteristične i za druge regije Evrope i svijeta. Zakonska regulativa se redovno usklađuje sa pravnom tekovinom Evropske unije, ali postoji nedostatak lako dostupnih informacija, koje bi alergičnim osobama olakšale proces dijagnosticiranja, preveniranja kontakta sa alergenima i snalaženje u svakodnevnom životu.

In general, the mixing the reactants is very important to the process and the rate of combustion of each fuel, especially low-ranked coals with low reactivity. The appropriate excess air coefficient for combustion and the position and mode of supply of individual portions (air sta- ging) of the total air in the furnace are one of the key influ- encing factors for the mixing, respectively the efficiency of the combustion process, and the level of emissions. Today, the air staging (primary, secondary, tertiary and over fire air-OFA) is an indispensable process in the design of new industrial and energy boilers. Also, this measures are used for the reconstru- ction of existing furnace of large boilers. The implementation of this primary measure in the furnace does not require signi- ficant financial resources - the costs of investing in the intro- duction of air staging supply for combustion in the furnace are very low in relation to the multiple positive effects and bene- fits of such a system, especially a lower NOx emissions. However, the first condition for the correct and reliable design of the air staging system in the furnace is the choice of the optimal position for the supply OFA air. Determination of this position on the furnace depends on several factors, primarily the type and characteristics of the fuel, grinding quality, co- mbustion technology, furnace structure, type, number and arra- ngement of burners. On this topic, the Faculty of Mechanical Engineering of the University of Sarajevo, in the Laboratory for Coal and Biomass Combustion, conducted extensive rese- arch on the pulverized combustion of coal blends of the Ce- ntral Bosnia Mining Basin, including co-firing of these coals with waste wood biomass (beech and spruce sawdust). Here is presented some of the results of those NOx emission studies for different fuels and combustion temperatures, depending on the mode of supply and the positions of the combustion air supply in the boiler furnace.
