Objective. The aim of this paper is to gain insight into changes in information needs and habits of users of the online reference service Ask the Librarians provided by Croatian public libraries since 2004. Methodology. Based on the research of Jagoda Ille and Helena Novak and the analysis of user information queries in the fi rst four years of service implementation from 2004 to 2008, an analysis of posted information inquiries was conducted from 2018 to 2022. By using the same methodology and time frame, the aim was to enable a comparative analysis of the obtained data regarding users' level of education, the number and type of information inquiries (divided into four categories: requests for direction, quick or factual information, bibliographic information and other inquiries), user satisfaction and the number of librarians involved in the service. Results. The research results for the period from 2018 to 2022 indicated a higher number of posted inquiries, a change in the educational structure of users and a change in the type of inquiries compared to the fi rst four years of service implementation from 2004 to 2008, as well as a constant increase in the number of librarians involved in the online reference service Ask the Librarians. Originality/Value. The value of the research lies in detecting changes in information inquiries and new information needs of users of the Croatian public libraries' online reference service Ask the Librarians, available to users since 2004.

The goal of this article is to explore – from the given theoretical framework – the effectiveness of the European Union’s data protection capabilities, namely through the General Data Protection Regulation. The first and second sections develop the theory of control societies – as well as its historical background – and connects it with the theory of surveillance capitalism as its essential component. The third section delas with some critiques that have arisen in the few years after the GDPR came into force. The conclusion of the paper is that, only a few years after the GDPR came into force, it is still too early to decisively say what effect will it have on the big data industry. However, from the problems that have been elaborated, it seems unlikely that the big data industry will be meaningfully challenged when it comes to data protection.

LIBRARIES , *DATA analysis , *SEMANTIC Web , *UNIFORM Resource Identifiers , *LIBRARY catalogs - Abstract
The paper brings a review of the linked data concept as a semantic upgrade of the existing World Wide Web. It also analyzes the possibility of integrating library catalog and services into the intelligently linked network -- semantic web. The irst part of the paper presents some basic principles of the semantic web in general. Then we discuss the main elements of the linked data (URI - Uniform Resource Identifiers and RDF - Resource Description Framework), its principal concepts, publishing procedure, licensing and some security issues. The next section explains the main advantage of linked data searching in comparison with the conventional web search. Furthermore, we discuss the application of linked data on library catalogue records. MARC properties are analyzed in a network environment as well as the difference between catalogue with linked data and traditional library catalogue. The analysis has shown that MARC record is only readable, while the same record in RDF/XML format integrated into linked data is also understandable in the semantic sense. The conclusion is that the linked data technology presents a great opportunity for further development of library catalogues and library services, but also a was to improve eficiency in the intelligently linked global network.

Ovaj rad je opisao koncept okruženja Interneta stvari i važnosti kibernetičke sigurnosti u modernom svijetu. Dan je pregled osnovnih elemenata umjetne inteligencije u kontekstu neuronskih mreža koje su zatim korištene kako bi se pokušao izgraditi osnovni element nadzornog alata koji bi detektirao kibernetičke napade u IoT mrežama. Rad je obradio tri pristupa ovakvom alatu, jedan koristeći isključivo analizu metrika dostupnih na rubnim uređajima, te dva različita pristupa s gledišta umjetne inteligencije kojima se isti alat pokušao realizirati uz pomoć analize mrežnog prometa rubnih uređaja. Posljednja poglavlja ovog rada prilažu rezultate i prijedloge za buduća istraživanja. This paper describes the concept of an IoT network and the importance of cybersecurity in the modern world. An overview of basic elements used in the field of artificial intelligence was given. Specifically, an overview of neural networks which were then used as a foundation upon which a cyberattack detection system would be built in order to detect such hazards in an IoT network. The paper presents three approaches to creating such software, one of which exclusively analyses the telemetry data collected on the edge devices themselves, whilst the other two employ different artificial intelligence strategies in order to build software which would analyze the network traffic in the IoT edge layer. The final chapters present the final results and provide suggestions for future research.

Natura 2000 is the European ecological network established to protect important habitat areas and to maintain the biodiversity of the European Union. The network consists of the Special Protection Areas (SPA) selected in accordance with the Directive on the Protection of Birds, and the Special Areas of Conservation (SAC) selected in accordance with the Directive on the conservation of natural habitats and wild fauna and flora. During the EU accession process, the Republic of Croatia has had to harmonize the legal framework for the environmental protection and to propose sites for the Natura 2000 network. This paper describes proposed sites mapping process and gives a brief summary of the INSPIRE Data Specification on Protected Sites according to which the spatial data of the ecological network should be adjusted.

DISTRIBUTION (Economic theory) , *FOREIGN investments , *SPATIAL analysis (Statistics) , *INVESTORS , *DATA analysis , *QUALITATIVE research - Abstract
The paper presents the results of research of spatial and national distribution of foreign direct investments in Bosnia and Herzegovina through quantitative and qualitative analysis of the available data. For a better insight into the origin of investments and possible geopolitical interest of the investors, investing countries are grouped according to the criteria of similarity. The spatial distribution of foreign direct investment presented at the entity level complements insight into the connection between national or religious affiliation with the origins of the investment. Furthermore, analysis of foreign direct investment by sector of activity indicates a possible orientation of investing countries towards target branches of the economy. Using various geographic graphical methods, processed data are presented by a series of parallel graphics. Mutual incompatibility of the information provided by various state authorities in Bosnia and Herzegovina produced some problems in processing of data. However, according to this analysis, the article confirms the initial assumption about the connection between the geopolitical interests of the countries investors and recipients in Bosnia and Herzegovina.

OCCUPATIONAL diseases , *COMMUNICABLE diseases , *MEDICAL care , *PREVENTIVE medicine , *DATA analysis , *COMPARATIVE studies , *DISEASE risk factors - Abstract
In the Republic of Croatia, occupational infectious diseases are defined in the Act on the List of Occupational Diseases as "infectious or parasitic diseases transmitted to people from animals or animal remains" and as "infectious or parasitic diseases caused while working in circumstances with proven increased risk of infection." The paper discusses the data on the occupational infectious diseases recorded in the Register of Occupational Diseases maintained by the Croatian Institute for Health Protection and Safety at Work for the period from 1st January 2001 to 31st December 2010. The occupational infectious diseases in the Register are reviewed according to their overall incidence, their portion in the total number of occupational diseases in the Republic of Croatia, according to the type of disease, occupation of the infected workers and the employers' business. From 2001 to 2010 the Register records show a total of 1054 occupational diseases, of which 10% were infectious diseases. When compared to other occupational diseases, the incidence of infectious diseases occupies a high third place, and in some years within the studied period even the second or first place. The most common occupational infectious disease was tuberculosis, followed by different types of hepatitis and zoonoses, Q fever and hemorrhagic fever. Zoonoses occur most commonly in agriculture, forestry and veterinary practice. Tuberculosis and hepatitis occur among health care workers, nurses in particular. Given that the results indicate a steadily increasing incidence of tuberculosis in the overall number of occupational infectious diseases, additional cautionary measures should be taken, especially in health care, to prevent further increase in the number of infected individuals.

PRECIPITATION variability , *METEOROLOGICAL stations , *DATA analysis , *RAIN gauges , *METEOROLOGY - Abstract
The paper deals with spatial differences in precipitation variability in Central Croatia. Precipitation variability is analysed for 8 meteorological stations for which data for the 1950-2007 period are available. All the researched stations have a continental pluviometric regime. The annual values of mean relative variability in the studied area have relatively small range. The precipitation variability maximum occurs in Autumn at most of the stations, and the minimum in Spring. The annual course of precipitation variability is characterised, at all stations, by a maximum in October. The secondary maximum of precipitation variability occurs in January or February. The primary minimum of precipitation variability is in June at all stations apart from Sisak, where the minimum is in April. The secondary minimum is in March or April. There are spatial differences in precipitation variability, although not particularly pronounced, especially in the March till July period. [ABSTRACT FROM AUTHOR]

PSYCHOLOGICAL stress , *TEACHERS , *HIGHER education , *INTERPERSONAL relations , *QUESTIONNAIRES , *QUALITATIVE research , *DATA analysis - Abstract
The aim of this study was to determine the sources of stress in the work of university teachers working in Croatia and to construct a questionnaire that would enable quantitative studies in this area. A qualitative study, aimed to determine the sources of stress at work, was conducted on a convenience sample of 34 higher education teachers in different academic ranks (assistants and professors), working in twelve faculties of the University of Zagreb and University in Split. Using the method of guided group discussions, we identified 125 characteristic sources of stress in the work that are logically categorized into nine content groups. Based on a qualitative study, we have constructed Questionnaire of Exposure to Stress in the Work for University Teachers and apply it on a sample of teachers (N=388) from three Croatian universities. After the implementation of confirmatory factor analysis procedures, the final questionnaire contains 68 items, which define the seven latent dimensions of sources of stress: Teaching and students, Consequences of the Bologna reform, Scientific-research work, Role-conflict, Remuneration and recognition, and Interpersonal relationships. The paper presents data on the metric characteristics of the structured questionnaire, and descriptive results of the pilot application. [ABSTRACT FROM AUTHOR]

CATHOLIC priests , *EIGHTEENTH century , *HEADACHE treatment , *MEDICINAL plants , *DATA analysis - Abstract
Manuscripts containing collections of folk recipes for treatment of deseases were written mostly by Catholic priests especially Franciscians in Croatia in the past centuries. They were used as manuals for preparation of remedies and gave directions for their use. These writtings provide valuble data for etnographers and historians of ethnomedicine. The paper describes the manuscript "Many different remedies for headache treatment" written by unknown author probably in 18. century in Sinj, Dalmatia. The manuscript was found in the archives of Sinj Friary. The collection contains 16 recipes for headache treatment. Materia medica of the manuscript is composed of drugs of plant origin. Valuable information is given about the folk names for medicinal plants as well as descriptions of the ways of preparing remedies. Latin as well as contemporaly croatian names are attributed to the plants species mentioned in the manuscript. Use of the plants for treatment of the specific deseases were compared with their use in modem fitotherapy [ABSTRACT FROM AUTHOR]

tourist traffic of island Hvar ,data analysis ,primary data ,tourist market research ,secondary data - Abstract
Ovaj završni rad govori o primjeni sekundarnih podataka u istraživanju turističkih tržišta. U prvom dijelu rada napisane su opće informacije o marketinškom informacijskom sustavu, primarnim i sekundarnim podacima i metodama kojima se do njih dolazi. Govori se o značaju sekundarnih podataka za istraživanje turističkih tržišta , a osobito zbog lakšeg načina njihovog prikupljanja koji je ujedno i mnogo jeftiniji i brži od načina na koji se dolazi do primarnih podataka. Drugi dio rada govori o otoku Hvaru i to o njemu prvenstveno kao turističkoj destinaciji s time da se govori i o povijesti samog otoka, a zatim slijedi usporedba turističkog tržišta između administrativnih jedinica otoka Hvara u posljednje četiri godine, a to su Općina Jelsa, Općina Sućuraj, grad Stari grad i grad Hvar. Na temelju podataka iz eVisitora, koji spadaju u sekundarne podatke, uspoređuje se broj posjeta i broj noćenja turista u te 4 jedinice za posljednje četiri godine te se izvodi zaključak da li su neke od tih jedinica posjećenije više od ostalih, da li se taj broj posjeta i noćenja povećava ili smanjuje iz godine u godinu, kolika je razlika u posjetima ovisno općini odnosno gradu, a sve da bi se na temelju dobivenih podataka izvukao zaključak o turizmu na otoku Hvaru u te posljednje 4 godine., The paper focus on the usage of secundary data in the research of tourist market. In the first part deals with informations about marketing information system, followed by informations about primary and secundary dana and metods of usege. The importance of secodary data for analysis of tourist market is highlighted. The second part of paper is about the island Hvar, especially as a tourist destination with the focuos on the comparasion of tourist market between administrative units of island Hvar in the last four years. Those administrative units are: municipality Jelsa and Sućuraj and city of Hvar and city of Stari grad. Using secondary data from eVisitor in this work the number of tourists and overnights in this units for last four years are compared. According to those informations it is possibile to conclude are some units more visited than others and that the structure is changing over years.

U ovome se radu obrađuju alati i metode prikupljanja podataka te se raspravlja o etičnim pitanjima kod svakog pojedinačnog elementa procesa prikupljanja podataka. Na početku rada se pobliže pojašnjavaju pojedinačni elementi procesa analize podataka pod kojem spada i proces prikupljanja podataka kao drugi korak poslije postavljanja ciljeva a prije obrade i tumačenja i prikazivanja rezultata. Nadalje, kreće se u obradu alata pomoću kojih se provode procesi prikupljanja podataka. Pod klasične metode svrstavaju se govor i ručne metode (sredstva za pisanje). Pod moderne metode svrstavaju se telekomunikacije i Internet. U nastavku rada obrađuju se metode putem kojih se prikupljaju podaci a to su: anketa, intervju, fokus grupa, opažanje te rudarenje podataka. Od navedenih metoda anketa, intervju, fokus grupa i opažanje spadaju pod klasične metode dok rudarenje podataka spada pod moderne. Pri kraju rada, spajaju se klasični i moderni alati i metode prikupljanja podataka te se kroz dva aspekta (iskrivljenje rezultata istraživanja i svjesnost sudjelovanja u istraživanju) detaljnije razrađuje tema etičnost alata i metoda. This paper discusses the tools and methods of data collection and discusses the ethical issues in each individual element of the data collection process. At the beginning of the paper, the individual elements of the data analysis process are explained in more detail, which includes the data collection process as the second step after setting goals and before processing and interpreting and presenting the results. Furthermore, it moves to the processing of tools by which data collection processes are carried out. Classical methods include speech and manual methods (writing aids). Modern methods include telecommunications and the Internet. In the continuation of the paper, the methods by which data are collected are discussed, which are: survey, interview, focus group, observation and data mining. Of these methods, survey, interview, focus group and observation fall under the classical methods while data mining falls under the modern ones. At the end of the paper, classical and modern tools and methods of data collection are combined, and through two aspects (distortion of research results and awareness of participation in research) the topic of ethics of tools and methods is elaborated in more detail.

Nepristupačnost podataka o akademskim radovima predstavlja poseban problem za analizu i pregled podataka. Servisi koji poslužuju ovakve podatke obično nemaju sve potrebne podatke, ne prate odredenu strukturu podataka ili imaju druga ograničenja poput broja podataka koje je mogu´ce preuzeti, vremenski okviri u kojima je podatke moguće preuzeti, posebni zahtjevi na pristup podacima, zabrana izvođenja analize nad preuzetim podacima i tome slično. Cilj ovog rada bio demonstrirati jednostavnijei pristupačnije rješenje za korištenje podataka o akademskim radovima u svrhu analize i pregleda podataka. Predloženo je prikupljanje, obrada i pohrana podataka. Za prikupljanje podataka korišteni su skriptni jezici. Oni ubrzavaju razvoj privremenih sustava svojom pristupačnošću i visokom razinom apstrakcije. Obrada podataka napravljena je nad prikupljenim podacima u više koraka. Nakon analize prikupljenih podataka, svi podaci koje je bilo moguće dobiti iz podatkovnog izvora pretvoreni su u predloženi format. Opisane su i odredene metode za ubrzavanje obrade podataka. Sustav je predloženo otvoriti za korištenje kako bi potakli kolaboraciju i daljnji razvoj. Opisano je postavljanje sustava u produkcijsko okruže, osiguravanje prometa podataka i različiti načini za posluživanje podataka. The lack of availability of information on academic papers is a problem, especially if they are to be used for analysis and data overview. Services that provide such information usually do not have all the information required, do not follow a particular data structure, or have other limitations such as the amount of data that can be downloaded, time frames within which data can be retrieved, data access requirements, disallowing data analysis on downloaded data, and the like. The aim of this paper was to provide a simpler and more accessible solution for using academic data for analysis and data overview. Data collection, processing and storage methods are suggested. Scripting languages were used to collect data. They accelerate the development of temporary systems with their accessibility and high level of abstraction. Collected data was processed in several steps. After analyzing the data collected, all the data that was available from the data source was converted into the proposed format. Some methods for accelerating data processing are also described. The system was proposed to be opened for use to encourage collaboration and further development. System setup for production environment was described as well as data transfer security and various ways of serving data.

Brendiranje gradova i destinacija je važan proces koji se već godinama uvelike razlikuje od brendiranja države. Dok se država brendira kao cjelina, brendiranje gradova fokusira se na posebnosti manje geografske jedinice. Brendiranje gradova može utjecati na reputaciju gradova unutar iste države, regije ili na međunarodnoj sceni. Ovaj rad obuhvaća pojmove vezane za brendiranje gradova s naglaskom na New York koji je već desetljećima jedan od najjačih gradskih brendova. Analiza kreće od općenitih pojmova o načinu bredniranja gradova, kriterijima koji se uzimaju u obzir kada se promatra vrijednost brenda i usporedbu s drugim poznatim primjerima uspješnog bredniranja gradova i manjih država poput Novog Zelanda. Također jedno od poglavlja posvećeno je osvrtu na američku kulturu i utjecaj kroz kulturnu industriju, s posebnim naglaskom na filmsku industriju. Rad se potom osvrće na prve marketinške kampanje koje su provedene sedamdesetih godina prošlog stoljeća, s osvrtom na povijest grada i stvaranjem logotipa I ♥ New York koji je do dan danas ostao najpoznatiji logotip grada na svijetu. Izuzev toga, rad obuhvaća i kratku povijest kazališne industrije i ulice Broadway koja je igrala bitnu ulogu u kulturnoj industriji grada. Analitički dio se sastoji od analize filmova i tv serija koje su smještene u New Yorku, pregleda najpoznatijih lokacija te usporedbom broja filmova snimljenih u New Yorku u odnosu na druge lokacije u svijetu. Zaključak rada jest da je New York usprkos tome što je relativno mlad grad bez prirodnih i povijesnih znamenitosti uspio zauzeti visoko mjesto na svjetskoj ljestvici destinacija s najjačim gradskim brendom., Cities and destination branding has become important process and in past few years it greatly differs from state brading. While country branding refers to a country as a one unit, cities and destinations branding focuses on one particular geographical unit. Cities branding can influence one city's reputation among cities in the same country, region or on international scale. This paper explains topics connected to the city branding with ephasis on New York which has, for decades had one of the strongest cities brands. The analysis starts from general concepts that define city branding, criteria which are taken into consideration when defining city brand value, and comparment to other succesfull projects of cities and smaller states branding, one of which is New Zeland. Also, one of the chapters reviews american culture and it's influence trough strog cultural industry with special emphasis on film industry. Further analysis in the paper is after focused on the first marketing campaigns that were started back in the 1970's, with research of the city's history and creation of I ♥New York logo, which has, to this day remained most famous logo belonging to one city. Above that, the paper contains short review of the history of the theather industry and Broadway street which has had major role in shaping city's cultral industry. Analytical part is made of analysis focused on observing movies and tv shows set in New York, overview of most famous location and compairment of number of movies filmed in New York and other cities. The conclusion of the whole paper is that New York, despite being relatively young city, succeded in becoming one of the world's most famous city brands.

Dijabetes je bolest čije posljedice mogu ozbiljno ugroziti zdravstveno stanje bolesnika. Ukoliko dođe do komplikacija, one mogu utjecati na kvalitetu života i životni vijek. Upravo zbog toga ova bolest zahtijeva redovito praćenje i regulaciju bolesti. Dostupnost elektroničkih rezultata mjerenja omogućava akumulaciju velikih količina podataka kojima mogu pristupiti svi uključeni u liječenje (liječnici, pacijenti i sl.). Štoviše, s obzirom da je dijabetes bolest koja traje cijeli život, čak i podaci jednog pacijenta mogu biti brojni a njihova interpretacija kompleksna. Zbog navedenih razloga postoji čitav niz metoda i alata koji su dizajnirani i izvedeni za praćenje podataka o razini glukoze u krvi "od kuće". Osim statističkih metoda, glavne metode korištene u ovom radu su modalni dan (grupiran prema danu u tjednu, mjesecu u godini te prema tome je li dan bio radni ili neradni) i graf trenda. Modalni dan je prikaz standardnog dana koji prikazuje vrijednosti mjerenja podijeljena u kategorije određene satima u kojima su mjerene. Graf trenda ilustrira vrijednosti mjerenja poredane slijedno. Sve navedene funkcije su izvedene kao MATLAB funkcije. Rad također stvara temelj za dubinsku analizu podataka koja omogućuje temeljitiju obradu podataka o razini glukoze u krvi. Diabetes is a serious disease which can affect the entire body. If complications develop, it can have a significant impact on quality of life and can reduce life expectancy. That is why this disease requires daily self care and monitoring. The availability of electronic health records and monitoring facilities is leading to accumulating huge data sets that are accessible to doctors, patients or any other health care decision makers. Moreover, because diabetes is a lifelong disease, even data available for an individual patient may be massive and difficult to interpret. Therefore a variety of methods and tools have been designed and implemented to support interpreting blood glucose home monitoring data. Except the statistic methodes, the main methodes explained in this paper are glucose modal day reports (sorted by day of the weeek, month of the year, working and nonworking days) and trendgraph. The glucose modal day report shows the daily pattern of glucose levels over the specified date range. A trendgraph illustrates the activity or progress of blood glucose levels monitored as time series data. All those methodes are implemented as MATLAB functions. This paper is also a short introduction to data mining which improves data analysis of blood glucose level.

Temperatura i vlažnost zraka dvije su najčešće mjerene atmosferske veličine, što se može i očekivati s obzirom da je većina fizičkih, elektronskih, kemijskih, mehaničkih i bioloških sustava pod utjecajem temperature i vlažnosti. U radu je prikazan primjer mjerenja temperature, vlažnosti i intenziteta svjetlosti uz pomoć mikroupravljača. Izmjerene vrijednosti u realnom vremenu, šalju se na računalo serijskom komunikacijskom vezom te analiziraju i prikazuju uz pomoć Matlab-a. Prikazano je i razvojno okruženje Arduino koje se koristi za mjerenje fizikalnih veličina, a jedno je od najpopularnijih razvojnih platformi u današnjem akademskom i inženjerskom svijetu., Temperature and humidity are two most commonly measured atmospheric values as can be expected, since most of physical, electronic, chemical, medical and biological systems are influenced by them. This paper presents an example of measuring temperature, humidity and light intensity realized by microcontroller. Real time measured values are sent to the computer by serial communication link then analyzed and displayed in MATLAB. The paper also presents Arduino development environment, used for measuring physical variables. Thus it is represented as one of the most popular development platforms in todays academic and hobby engineering world.

Turistički sektor može polučiti velike benefite od kvalitetne primjene analize podataka. Kvalitetan uvid u dinamiku rezervacija smještaja, potražnju i potrebe klijenata može ponuđaču turističkih usluga dati mogućnost donošenja poslovnih odluka koje će s jedne strane dodatno podići kvalitetu ponude i zadovoljstvo klijenata, a s druge rezultirati većim profitima. Zadatak ovog rada jest prikupiti podatkovni skup povezan uz turistički sektor, provesti eksploratornu analizu nad tim podacima i razviti prediktivni model za odabrane zavisne varijable. Konačno rješenje potrebno je realizirati u obliku programske skripte koje će implementirati razvijene modele i evaluirati njihovu učinkovitost uz komparativnu analizu korištenih metoda. The tourism sector can benefit from the quality application of data analysis. Quality insight into the dynamics of accommodation reservations, demand and customer needs can give the tourism service provider the opportunity to make business decisions that will on the one hand, further raise the quality of the offer and customer satisfaction, and on the other hand, result higher profits. The task of this paper is to collect a data set related to the tourism sector, to implement exploratory analysis of these data and develop a predictive model for selected dependent variables. The final solution needs to be implemented in the form of a program script that will implement the developed models and evaluate their effectiveness with comparative analysis of used methods.

Napadi na komunikacijsku mrežu predstavljaju problem ostvarenja sigurnosti podataka. Detekcija napada i provođenje ispravnih postupaka za njegovo otklanjanje jedan su od glavnih načina borbe protiv napada. Tema napisanog rada je analiza podataka koji predstavljaju promet mreže i gradnja klasifikatora koji bi prepoznavali razrede napada. Analizom podataka ustanovljena je neravnomjerna rasprostranjenost podataka između razreda. Naduzorkovanjem pa poduzorkovanjem je uklonjen taj problem te su ponovljeni algoritmi klasifikacije. Pokazalo se da su se rezultati klasifikatora poboljšali. Modeli s najboljim rezultatima su ekstremno pojačavanje gradijenta i stroj potpornih vektora. Klasifikatori su postizali točnost od 49\% do 79\%. Model koji je imao najlošiju točnost prije naduzorkovanja i poduzorkovanja, ali kojem se i točnost povećala za 15\% je naivni Bayesov klasifikator. Attacks on the communication network are a problem of data security. Detecting an attack and carrying out the correct procedures to eliminate it are one of the main ways to fight an attack. The topic of this paper is the analysis of data representing network traffic and the construction of classifiers that would identify attack classes. Data analysis revealed an uneven distribution of data between classes. Oversampling and then undersampling over data removed this problem and the classification algorithms were repeated. Classifier results have been shown to improve. Model with best results are Extreme gradient boosting and Support vector machines. Classifiers achieved accuracy from 49% to 79%. The model that had the worst accuracy before oversampling and undersampling, but whose accuracy also increased by 15% is Naive Bayes classifier.

Korištenje društvene mreže Reddit postaje sve važnije u analizi i vizualizaciji podataka. U sklopu ovog završnog rada implementiran je radni okvir za analizu podataka s Reddita te vizualizaciju istih. Napravljena je deskriptivna analiza podataka, a sami podaci prikupljeni su sa r/croatia subreddita. Podaci su razvrstani u kategorije u skladu s Redditovom implementacijom sortiranja podataka po određenim parametrima. Za svaku kategoriju u obzir se uzima score (razlika pozitivnih i negativnih ocjena na objavi) te broj komentara kako bi se samoj objavi odredila popularnost. Glavna tema proučavanja bili su gradonačelnički i lokalni izbori 2021. godine te objave vezane uz iste. The use of the social network Reddit is becoming increasingly important in the analysis and visualization of data. As part of this final paper, a framework for the analysis of data from Facebook and their visualization has been implemented. A descriptive analysis of the data was made, and the data themselves were collected from r / croatia subreddita. The data are categorized according to Reddit’s implementation of sorting data by specific parameters. For each category, the score (difference between positive and negative ratings on the post) and the number of comments are taken into account in order to determine the popularity of the post itself. The main topic of the study was the mayoral and local elections in 2021 and the announcements related to them.

Funkcionalno programiranje jedna je od programskih paradigmi koja ima mnoge primjene. Jedna od primjena funkcionalnog programiranja je analiza podataka. U ovom radu je u programskom jeziku F# ostvaren program za analizu podataka. Taj program analizira podatke o emisijama ugljikovog dioksida, BDP-u i postotku korištenja energije dobivene iz obnovljivih izvora za pojedine regije u svijetu računajući Pearsonov i Spearmanov koeficijent korelacije. Prije izračunavanja koeficijenata korelacije potrebno je dohvatiti podatke iz CSV datoteke te filtrirati vrijednosti potrebne za izračun koeficijenata. Pomoću grafičkog sučelja implementiranog u jeziku C#, program omogućuje prikaz vrijednosti koeficijenata za izabranu regiju kao i prikaz grafova vrijednosti indikatora te regije. Iz izračunatih koeficijenata korelacije može se vidjeti jesu li indikatori korelirani i podudaraju li se vrijednosti Spearmanovog i Pearsonovog koeficijenta korelacije ili među njihovim vrijednostima postoji veća razlika. Functional programming is one of the programming paradigms that has many applications. One of which is data analysis. In this paper F# was used to realize a program for data analysis. That program analyses carbon dioxide emissions, GDP and percentage of renewable energy use data for individual regions in the world by calculating Pearson’s and Spearman’s correlation coefficients. Before calculating correlation coefficients, it is necessary to extract data from CSV file and filter it so that only the needed values remain. Through graphical user interface implemented in C# the program enables display of values of the coefficients for chosen region as well as charts which display values of the indicators. From calculated correlation coefficients it is possible to see if the indicators are in correlation and whether the values of Spearman’s and Pearson’s coefficients match or is there a difference between them.

Zloćudne obitelji koje koriste algoritme za generiranje imena domena se svakodnevno ažuriraju i kompromitiraju sve više novih poslužitelja. Istraživači konstantno ulažu napore u smišljanje klasifikatora koji bi uspješno detektirao sve nove umjetno generirane domene, no nailaze na mnoge prepreke od kojih su najznačajnije ogromna količina računalnih resursa i analiza mrežnog prometa. Cilj ovog rada je objasniti zbog čega je detekcija umjetno generiranih domena zahtjevan problem i prikazati performanse različitih klasifikatora koji su se pokazali kao dobrim modelima za detekciju. Malicious families based on domain generation algorithms are updated daily and keep on compromising new servers on a daily basis. Researchers are constantly making efforts to create a classifier that would successfully detect all new artificially generated domains but they encounter many obstacles, the most significant of which are the huge amount of computer resources and network traffic analysis. The aim of this paper is to explain why the detection of algorithmically generated domains is a complicated problem and to present the performance of different classifiers that have proven to be good models for detection.

Digitalni se marketing po mnogo čemu razlikuje od tradicionalnog marketinga, a u novije doba ulaganja u digitalni marketing premašuju ulaganja u tradicionalni marketing. Utjecaj društvenih mreža rapidno raste i nadilazi tradicionalne kanale komunikacije. Društvene su mreže postale iznimno važne za uspješno poslovanje. Kompanije mijenjaju svoje organizacijske postavke i poslovanje razvijajući digitalne kanale promocije i podrške s ciljem stjecanja konkurentske prednosti. Među važnijim karakteristikama digitalnog marketinga jest da su kupci konstantno dostupni, a njihova je reakcija promptna. Brz rast korištenja pametnih uređaja mijenja navike korisnika. Stvarna važnost digitalnog poslovanja nije u nastanku novih tehnologija, nego upravo u promjeni ponašanja kupaca. Targetiranje predstavlja jednu od osnovnih prednosti digitalnog oglašavanja i daje mogućnost visoke preciznosti u plasiranju oglasa ciljanoj publici. Korištenje društvenih mreža omogućava mjerenje broja posjetitelja na web stranici, njihovo kretanje, preferencije i navike. Kompanije, koje prepoznaju važnost društvenih mreža, ulažu velike napore u analizi dobivenih podataka za kreiranje taktičkih planova. Cilj je rada prikazati, na primjeru HT Mostar, kretanja i ponašanja korisnika u promotivnoj kampanji putem digitalnog marketinga te utvrditi njegovu važnost u prikupljanju i analizi korisničkih podataka, s ciljem preciznijeg pozicioniranja kompanije i efikasnijeg korištenja digitalnog marketinga., Digital marketing differs in many ways from traditional marketing, and recently investments into digital marketing have exceeded investments into traditional marketing. Influence of social networks rapidly grows and goes beyond traditional communication channels. Social networks have become very important for successful business. Companies change their organization settings and business by developing digital channels of promotion and support with the aim of gaining the competitive advantage. Constant availability of customers and their prompt reaction belong to more important characteristics of digital marketing. Fast growth of using smart devices changes customers’ habits. The real importance of digital business is not in the emergence of new technologies, but in the change of customers’ behavior. Targeting represents one of the basic advantages of digital advertising and gives the opportunity for high precision in placing of advertisements to the target audience. Using of social networks allows measuring the number of visitors to the web site, their movement, preferences and habits. Companies, which recognize the importance of social networks, make great efforts in the analysis of the received data for creating tactical plans. Using the example of HT Mostar, the aim of this paper is to show movements and behavior of users in the promotional campaign through digital marketing and to determine its importance in collecting and analysis of the user data with the aim of more precise positioning of the company and more efficient using of digital marketing.

Grupiranje velikog skupa podataka na temelju grafova je ne toliko istražena metoda grupiranja. U ovom radu je opisan pojam crtanja grafova i pojam grupiranja podataka. Prikazana su najvažnija obilježja za svaki pojam uz popratne slike. U implementaciji programske potpore od softvera za crtanje grafova je korišten Networkx, uz crtanje metodom temeljene na sili. Za grupiranje podataka bio je iskorišten model centroida uz algoritam k-sredine. Na kraju su prikazani rezultati izvođenja programa. Grouping a large dataset based on graphs is not so much researched method of clustering. This paper describes the concept of drawing graphs and the concept of data grouping. The most important features for each term with accompanying images are presented. Networkx was used in the implementation of program support from graph drawing software, drawing by force-based method. The centroid model with the K-means algorithm was used to cluster the data. The results of the program's performance are shown at the end.

Današnja se istraživanja u području obrazovanja zasnivaju na upotrebi odgovarajućih pristupa prikupljanju podataka te suvremenim modelima njihove analize. Metodološki su iskoraci u ovom području znatni, a istraživači u posljednjih nekoliko desetljeća prepoznaju važnost primjene longitudinalnih nacrta u obrazovnim istraživanjima. Također, uviđanje hijerarhijske organizacije prikupljenih podataka i njihova odgovarajuća statistička obrada postaju metodološki imperativ. U ovom je radu pružen metodološki pregled hijerarhijske i longitudinalne organizacije podataka te teorijski okvir njihove statističke analize. Istaknute su najčešće pogreške i poteškoće s kojima se istraživači prilikom korištenja ovih metoda susreću te načini kako ih ispravno prevladati. Kroz jednostavne i svakodnevne primjere pokušalo se čitatelju približiti ove metode i njihovu statističku podlogu te uputiti istraživače u području obrazovnih istraživanja na njihovo adekvatno korištenje., Contemporary educational research is based on the use of appropriate research designs, comprehensive data assessments and contemporary models of the data analysis. Methodological breakthroughs in this area, over the last few decades, are significant, and researchers have recognized the importance of longitudinal research designs. Moreover, the understanding of the hierarchical organization of collected data and the application of corresponding statistical analyses becomes a methodological imperative. This paper provides a methodological overview of hierarchical and longitudinal data organization and the theoretical framework of their statistical analysis. Most common errors and difficulties in the application of those methods are highlighted, and the approaches on how to overcome it are suggested. Through simple and everyday examples, these approaches are presented to the readers, and educational researchers are directed on how to adequately use it.

Rad obuhvaća teorijsku podlogu o praćenju zdravlja te računanju ocjene vremena kao i dokumentaciju razvijene programske podrške. Praćenje korisnikovog zdravlja uključuje različite parametre tijela. Neki od najbitnijih su masa, tjelesna temperatura, krvni tlak, broj otkucaja srca, dnevni unos i potrošnja nutrijenata i kalorija. Aplikacija sadrži podatke za preko 8000 vrsta hrane. Za svaku vrstu sadrži nutritivne vrijednosti kao što su kalorije, masti i proteini. Zbog meteoropata, vrlo je važno evidentirati parametre vremena. Neki od najbitnijih parametara vremena su temperatura zraka, vlažnost i tlak zraka. Razvijena programska podrška podržava unos različitih parametara zdravlja, dok parametre vremena evidentira sama. Sve prikupljene podatke prikazuje i analizira na zajedničkom grafu kako bi se što bolje prikazala međuovisnost između što više parametara. This paper work includes the theoretical knowledge of health monitoring and weather rating calculation and also documentation of software developed for this purpose. Health monitoring includes many different health parameters. Some of the most important are weight, body temperature, blood pressure, heart beats, daily nutrient and calories intake and consumption. Application contains details for over 8000 types of food. For each type of food there is nutrient information such as calories, fat and proteins. For meteoropathic subjects, it’s very important to record weather parameters. Some of the most important weather parameters are air temperature, humidity and air pressure. Developed software supports adding different user health parameters, while application records weather on its own. All gathered data are displayed and analysed at mutual graph for improved insight in as many parameters interdependence.
