No full textOhranjanje narave in njenih virov vztrajno pridobiva na pomenu. Različne organizacije so v zadnjih letih napravile velik korak k boljšemu ozaveščanju ljudi o oskrbi za naš planet. Med te dejavnosti lahko uvrščamo tudi recikliranje. V diplomskem projektu smo se osredotočil na recikliranje izdelkov, kot so lesena okna, za katere reciklaža še ni našla pravih rešitev. Pri lesenih oknih se srečujemo z več materiali, kar nam samo recikliranje zelo oteži. Osnovni materiali v oknu so namreč kovine, steklo in les. V diplomskem projektu smo se osredotočili na reciklažo dveh materialov (les in steklo), iz katerih je bila izdelana hibridna kompozitna plošča. Za ploščo je bilo uporabljeno zmleto steklo in zmlet les, kot lepilo pa je bila uporabljena melaminska smola. Plošči so bile določene protitermitska odpornost, odpornost proti glivam in ognjevarnost. Rezultati kažejo, da dodatek stekla v ploščo ne vpliva bistveno na njene lastnostiPreserving nature and is resources steadily gaining in importance. Different organizations have taken a substantial step up to raise awareness of people about the care of our planet in recent years. These activities may also include the recycling. In this project we focused on the recycling of products, like wooden windows, for which recycling has not yet found the right solutions. Wooden windows are made from several materials, which makes recycling very difficult. The base window materials is metal, glass and wood. In this project we focused on the recovery of the two materials (wood and glass) from which it was made hybrid composite panel. For the plate were used ground glass, and ground wood, as an adhesive, was applied melamine resin. The plates were made tests for termite`s resistance, fungal resistance and flame retardance. The results obtained clearly indicates, that boards made from old wood, already have excellent properties, therefore addition of the glass do not improve their performanc

Zato se tudi v lesarstvu trudimo, da bi povečali odstotek izkoriščanja lesne surovine. Nezaželeno je, da bi se lesno surovino direktno uporabljalo za pridobivanje energije, a vseeno gre velik delež lesa prav v ta namen. V magistrskem delu smo želeli dokazati, da pomodrel les, ki ima precej nižjo tržno vrednost, še vedno lahko dobra vhodna surovina za proizvodnjo materialov z višjo dodano vrednostjo, kot na primer termično modificiran les. Uporaba tega lesa v veliki meri zavisi od njegovih lastnosti. Zato smo pomodrelem lesu in kontrolnemu nepomodrelem lesu določili klasične sorpcijske lastnosti, dinamično sorpcijo vodne pare, izmerili stični kot, določili kapilarni vlek, lastnosti namakanja, impregnabilnost, izpiranje učinkovin, odpornost proti glivam razkrojevalkam ter, upogibno trdnost in tlačno trdnost. Na podlagi vseh teh parametrov smo videli, da pomodrel les hitreje vpija vodo a ima še vedno enake mehanske lastnosti kot nepomodrel les.Preserving nature and its resources is steadily gaining on importance. Different organizations have in recent years taken a substantial step to raise awareness of people on care for our planet. Therefore, in the wood industry we are working hard to increase the use of wood as a raw material. It is not optimal from any point of view to use solid wood for energetic purposes, but still a large proportion of wood is misused for this way. In this master project, we wanted to prove that coloured wood, which has a lot lower market value, can still be a good input material for production of high added value materials such as thermally modified wood. However the use of such material depends on its properties. For this reason we tested the coloured and non-coloured control timber and defined their classic sorption properties, the dynamic sorption of water vapour, contact angle, determined capillary suction, long-term water uptake, impregnability, resistance to fungal decay, flexural strength and compressive strength. Based on all of these parameters, we have seen that the coloured wood absorbs water quicker but still has the same mechanical properties as a non-coloured timber

Praktična vrednost diplomskega dela se odraža v optimiziranem upravljanju zalog, kar prispeva k večji učinkovitosti in zmanjšanju stroškov v podjetju.This diploma thesis addresses the problem of internal traceability of packaging, castings, and rings within a company. The motivation for the thesis was to improve stock accuracy and traceability of materials, which are crucial for the efficient operation of the company. The aim of the work was to analyze the existing processes and propose solutions for better internal traceability. The research employed methods of observation and analysis of the current situation by conducting inventories and collaborating with different departments. We proposed the installation of scanning boards equipped with barcodes of materials, allowing better traceability between warehouses and production plants. We also proposed optimizing the production piece lists to improve the accuracy of inventories in the SAP system, which is an original solution to the problem. The findings show that the scanning boards and the optimized production picking lines will significantly improve the traceability of materials and reduce stock-keeping errors. The practical value of this diploma thesis is reflected in optimized inventory management, which contributes to increased efficiency and cost reduction in the company
Management of methicillin resistant strains of bacteria Staphylococcus aureus in homes for elderly
No full textUvod: Staphylococcus aureus je bakterija, ki jo najdemo na in v človeškem telesu, načeloma ni patogena, v določenih situacijah pa je sposobna povzročanja bolezni. Uspešno se prilagaja na različne spremembe v okolju. Kolonizira kožo, kožne žleze in sluznice, kar lahko povzroča okužbe pri ljudeh in živalih v obliki izpuščajev, vnetij kosti in možganskih ovojnic ter v napredovanju okužbe, septikemijo. Obvladovanje MRSA v domovih za starejše občane je velik izziv, čeprav smo priča napredku na področju higiene, pravil o preprečevanju in obvladovanju MRSA in morebitnega zdravljenja. Namen diplomskega dela je analizirati prakse obvladovanja MRSA v različnih domovih za starejše v Sloveniji. Ugotoviti stopnjo poznavanja problematike med zdravstvenimi delavci in različne pristope pri spopadanju z preprečevanjem in obvladovanjem okužb z MRSA. Metode dela: Pri naši raziskavi smo vključili kvantitativni in kvalitativni pristop z anketiranjem 106 zdravstvenih delavcev iz šestih različnih domov. Anketa vsebuje 24 vprašanj, ki ocenjujejo ozaveščenost, znanje, prakse in izzive pri obvladovanju MRSA. Rezultati: Rezultati so pokazali, da je ozaveščenost zdravstvenega osebja o MRSA povprečna (65 %), pri čemer so najbolj ozaveščene diplomirane medicinske sestre. Večina zdravstvenih delavcev meni, da potrebujejo več izobraževanj na temo MRSA. V domovih za starejše običajno izvajajo izolacijo okuženih stanovalcev v enoposteljnih sobah in dajejo velik poudarek higieni rok kot pomembnemu preventivnemu ukrepu. Glavni izzivi vključujejo izolacijo okuženih, dosledno spoštovanje higienskih standardov in sodelovanje s svojci. Razprava in zaključek: Rezultati raziskave niso pokazali jasne povezave med višjo ozaveščenostjo in manjšim številom okužb, kar kaže na potrebo po večplastnem pristopu. Z anketami smo dobili več zanimivih rezultatov, vključno s tem, da je zdravstvene delavce pogosto še vedno strah MRSA. Z raziskavo smo dobili vpogled, s kakšnimi izzivi se soočajo posamezni domovi za starejše. Spodbudno je, da so zaposleni izrazili željo po bolj pogostih in ciljnih izobraževanjih o MRSA. Priporočila za domove za starejše vključujejo povečanje števila izobraževalnih programov, izboljšanje higienskih protokolov in boljše sodelovanje s svojci. Dom za starejše 1 se je izkazal kot primer dobre prakse, saj dosega, kljub velikemu številu stanovalcev, najboljše rezultate pri obvladovanju MRSA zaradi visoke ozaveščenosti in učinkovitega pristopa pri reševanju težav.Introduction: Staphylococcus aureus is a bacterium found on and in the human body. While it is generally non-pathogenic, under certain circumstances, it can cause diseases. It successfully adapts to various environmental changes. It colonizes the skin, skin glands, and mucous membranes, potentially causing infections in humans and animals, such as rashes, bone inflammations, meningitis, and, in the progression of infection, septicemia. Managing MRSA in nursing homes poses a significant challenge, despite advancements in hygiene, rules for the prevention and control of MRSA, and possible treatments. The purpose: of this diploma work is to analyze MRSA control practices in various nursing homes in Slovenia, to determine the level of awareness among healthcare workers, and to examine different approaches to preventing and managing MRSA infections. Methods: In our study, we employed both quantitative and qualitative approaches, surveying 106 healthcare workers from six different nursing homes. The survey consists of 24 questions that assess awareness, knowledge, practices, and challenges in MRSA control. Results: The results showed that the awareness of healthcare staff regarding MRSA is average (65 %), with registered nurses being the most informed. The majority of healthcare workers believe that more training on MRSA is needed. Nursing homes typically isolate infected residents in single rooms and place a strong emphasis on hand hygiene as a key preventive measure. The main challenges include isolating infected residents, consistently adhering to hygiene standards, and collaborating with family members. Discussion and Conclusion: The results did not show a clear link between higher awareness and a lower number of infections, indicating the need for a multi-layered approach. The surveys provided several interesting insights, including that healthcare workers often still fear MRSA. The study gave us an understanding of the challenges faced by individual nursing homes. It is encouraging that employees expressed a desire for more frequent and targeted training on MRSA. Recommendations for nursing homes include increasing the number of educational programs, improving hygiene protocols, and enhancing cooperation with family members. Nursing home 1 stood out as an example of good practice, as it achieves the best results in controlling MRSA, despite having a large number of residents, due to high awareness and an effective problem-solving approach
Adaptation of study to the blind and visually impaired: comparison of Slovenian and Norwegian institutions
No full textUvod: Število invalidov, med katere uvrščamo tudi slepe in slabovidne, vpisanih na
univerze se v številnih državah povečuje. Samostojnost osebe se po pridobitvi izobrazbe
poveča predvsem zaradi socialnih dohodkov. Pomembno je, da pri pripravi učnih načrtov
študentov s posebnimi statusi ne izpuščamo, temveč jih integriramo v sistem po najboljših
močeh. Namen: V diplomskem delu smo predstavili problematiko slepih in slabovidnih v
njihovem študijskem obdobju. Primerjali smo Univerzo v Ljubljani in Univerzo v
Trondheimu, z vidika dostopnosti za slepe in slabovidne študente. Metode dela: Raziskava
je bila izvedena v obliki študije primera. Izbrana subjekta sta bila Univerza v Ljubljani in
Univerza v Trondheimu. Uporabljeno je bilo namensko vzorčenje. Podatke smo črpali iz
dokumentacije in intervjujev z izbranimi osebami na posameznih fakultetah. Rezultati: V
raziskavi smo se osredotočili nadostopnost prostorov, informacij in pripomočkov,
prilagoditve in dostopnosti študijskih obveznosti ter osebne izkušenje dela s študenti z
okvaro vida. Poglavitne razlike med univerzama, vključenima v raziskavo, izhajajo iz
pravilnika, ki je v Sloveniji zapisan zelo splošno, za vse študente s posebnimi potrebami na
Norveškem pa zelo natančno, s poglavji, ki se nanašajo neposredno na osebe z okvaro
vida. Raziskava je pokazala, da je število slepih in slabovidnih študentov, ki so fakultete
obiskovali v zadnjih desetih letih nizko, saj se številke na vseh vključenih fakultetah v
Sloveniji gibljejo pod deset, na Norveškem, pa kljub temu, da evidence ne vodijo,
poudarjajo, da jeteh študentov malo. Razprava in zaključek: Iz rezultatov lahko
sklepamo, da ustanove v Sloveniji, ki smo jih raziskali, morda res še niso kadrovsko,
organizacijsko in strokovno pripravljene na sprejem slepih in slabovidnih, kar pa ne
pomeni, da norveške ustanove, vključene v raziskavo, ki so formalno na to bolje
pripravljene, zagotavljajo dobro prakso vsem študentom. Populacijo slepih in slabovidnih
bi bilo tako treba vključiti v več tovrstnih raziskav, kar bi omogočilo globlji vpogled in
ugotavljanje potrebnih ukrepov. Razvoj kadrov je pomemben korak do ustvarjanja
univerze kot inkluzivne institucije. Tega ni lahko doseči, saj zahteva spremembo
razmišljanja tako družbe kot institucij. Delovni terapevti lahko prispevamo k spremembi
razmišljanja znotraj visokošolskih institucij, in sicer s specifičnimi izobraževanji in
osveščanjem zaposlenih.Introduction: In recent years the number of people with disabilities, including blind and
visually impaired, who are attending universities has increased in many countries. After
graduation, a person\u27s independence increases, mostly on account of social income. It is
important that we do not dismiss students with special statuses when preparing the
curriculum, but that we integrate them into the system to the best of our ability. Purpose:
The bachelor\u27s thesis presents the problems of the blind and visually impaired during their
studies. The University of Ljubljana and the University of Trondheim were compared in
terms of their adjustments to blind and visually impaired students. Methods: The research
was conducted in the form of a case study. The selected subjects were the University of
Ljubljana and the University of Trondheim. Dedicated sampling was used. Data were
drawn from documentation and interviews with selected persons at individual faculties.
Results: The research examined the areas of accessibility to premises, information, aids,
performance of study obligations, and personal experience with students with visual
impairment. The main differences between the two universities stem from the rules, which
are written in a very general way in Slovenia and do not cover everything that a blind or
visually impaired student would need for easier entry into studies. In Norway, the rules are
very detailed and include several chapters that relate directly to people with visual
impairments, enabling them an easier transition. The number of blind and partially sighted
students over the last ten years at the faculties included in the survey is low. In Slovenia
the numbers on all faculties were below ten, in Norway however they do not have an
evidence that tracks the numbers but they have stated that it is a small populations of
students that are visually impaired. Discussion and conclusion: It can be concluded from
the results that institutions in Slovenia may not yet be properly staffed, organized and
professionally prepared to accept the blind and visually impairedhowever, that does not
mean that the surveyed institutions in Norway provide good practice to all students. The
population of the blind and visually impaired should therefore be included in more
research of this kind, which would provide a deeper insight into the current situation and
identify the necessary measures, as the development of a qualified staff is an important
step towards creating a university as an inclusive institution. This will not be easy to
achieve as it requires a change in how society and institutions think. Occupational
therapists can contribute to a change in thinking within higher education institutions
through specific education and disability awareness
Volunteering in the project the Elders for elderly
No full textMagistrska naloga vključuje teoretične opredelitve oskrbe starejših v skupnosti, opredelitve projekta Starejši za starejše, prostovoljnega dela (in prostovoljnega dela s starimi) ter socialnega dela s starimi ljudmi. Te predstavljajo izhodišče raziskovanja, na katero se v empiričnem delu naloge vežejo vprašanja o poteku dela, njegovih prednostih in slabostih, pa tudi predlogi glede dela v projektu in projekta samega.
Bistvo mojega raziskovanja je vpogled v izkušnje z delom prostovoljcev projekta Starejši za starejše v občinah Vrhnika in Logatec.
Projektno delo opravljajo pretežno ženske, ki so bile v projekt povabljene. V njem delujejo več let, zanj pa so se odločile predvsem zaradi potrebe in želje po stiku z ljudmi in želje pomagati drugim. Njihovo delo je načrtovano in dogovorjeno vnaprej, sama izvedba pa jim dopušča dokaj odprte roke. Priprave na delo in podporo ob delu jim društvo zagotavlja predvsem v obliki usposabljanj, izobraževanj in pogovornih srečanj. Znajo pa za to poskrbeti tudi sami na različne možne načine. Obiski potekajo tako samostojno kot v paru, najavljeni ali nenajavljeni. Tudi izpolnjevanje ankete ne poteka vselej na isti način. Za delo so opredelili več potrebnih spretnosti in znanj in so zelo podobna že znanim in značilnim za socialno-delavno ravnanje. Prav tako tudi vloge, ki jih pri delu prevzemajo. Prostovoljci za svoje delo prejemajo predvsem manjše simbolične nagrade in zadovoljstvo na osebni ravni. Njihove stiske in težave so vezane tako na organizacijo in izvedbo dela kot na odnose med prostovoljci in starejšimi, na odnos javnosti do njihovega dela ali na dejavnike osebne narave. Četudi je delo vse prej kot enostavno, ga vrednotijo na pozitiven način. Ocenjujejo ga kot uspešno. Z delom v projektu so prostovoljci veliko pridobili. Predlogi, ki so jih podali, so zelo konkretni, vezani pa so na izvedbo dela, podporo pri delu in ozaveščanje.This Master\u27s thesis includes some key theoretical definitions of elderly care within a community, different characterizations of a project Starejši za starejše, voluntary work (and voluntary work with elderly) as well as gerontological social work. Those various definitions present a starting point for the research in the empirical part of the thesis, where the process of working with the elderly within the project Starejši za starejše is presented, together with some advantages and disadvantages and additional suggestions for further work in this project and its improvement.
The core of my research gives an insight into practical experience of working in the project Starejši za starejše in municipalities Vrhnika and Logatec.
Mostly women, who have been previously invited, partake in this project. Some have been active for a number of yearsmost have joined due to their need and desire to connect with people and help others. Their work is previously planned, but the actual execution of work gives them some freedom. Preparations and support are ensured by the organization in the form of practical training, courses and conversational meetings. However, also volunteers have many ways of ensuring that their work is quality. Visits of elderly are either individual or in pairs, they are both announced and unannounced. Additionally, the survey is not always conducted in the same manner. Working with elderly requires a series of different skills, similar to those that are typical and required for social work in general. Same goes with roles they partake while working with elderly. Volunteers are awarded in a form of small symbolic prizes but mostly with the feeling of personal satisfaction. Their hardships and distress are related to various factors: organization and execution of work, relationships amongst volunteers and elderly, public’s attitude towards their work and other factors of personal nature. While work with elderly is anything but easy, they regard it as positive. They rate it as successful. Volunteers state that they have gained a lot from working in this project. They give some concrete proposals, related to the execution of work, support at work and raising awareness
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
