Analysis and Modeling of Customer Requirements Management for Repair Service Companies

Većina današnjih tvrtki radi u natjecateljskom okruženju, što vodi ka potrebi povećanja konkurentne pozicije na tržištu. Da bi tvrtke bile konkurentne na tržištu moraju nužno optimizirati svoje unutarnje procese. Ta optimizacija zahtijeva poslovne modele koji predstavljaju strukturu poslovanja koja omogućava organizacijama analizu i simulaciju promjena prije implementacije. U radu je analizirana problematika upravljanja zahtjevima za servisom u servisnom centru te su primjenom odgovarajućih UML (engl. Unified Modeling Language) dijagrama prikazani poslovni procesi upravljanja tim zahtjevima. Razvijena je web aplikacija koja omogućava cjelokupni proces vođenja termina i evidencija lokacija predviđenih za servisere koji odlaze do krajnjeg korisnika. Predloženi način upravljanja zahtjevima u servisnom centru omogućava povećanje kvalitete usluge servisera i minimiziranje troškova pružanja usluge.Most of today's businesses operate in a competitive environment, leading to the need to increase their competitive position in the market. In order to be competitive in the market, companies must necessarily optimize their internal processes. This optimization requires business models that represent a business structure that enables organizations to analyze and simulate changes before implementation. The paper analyzes the problems of managing service requests in a service center and presents the business processes of managing these requests using the appropriate Unified Modeling Language (UML) diagrams. A web application has been developed that enables the complete process of keeping dates and records of locations intended for end-user repairers. The proposed method of managing requests in a service center allows to increase the quality of service of the servicer and to minimize the cost of providing the service

Planning Migration from IPv4 to IPv6 Protocol

Internet protokol IP je internetski protokol mrežne razine koji ima osnovne funkcije adresiranja i usmjeravanja, odnosno prijenos datagrama kroz mrežu. Prilagođava se izvedbama prijenosne mreže i osigurava prijenos jedinica podataka. Postoje dvije verzije Internet protokola, a to su Internet Protokol verzije 4 i Internet Protokol verzije 6. Internet Protokol verzije 6 (IPv6) zamjenjuje Internet Protokol verzije 4 (IPv4) kao Internet standard, te je sljedeća evolucija Internet protokola. IPv6 protokol donosi nova poboljšanja koja bi trebala doprinijeti bržem i sigurnijem prijenosu podataka. Primjer primjene protokola IPv4 i IPv6 u radu je prikazan pomoću programskog alata Cisco Packet Tracer.Internet Protocol IP is an online network protocol that has basic functions addressing and routing, or transferring data across the network. It adjusts Performs transmission networks and ensures data transfer. There are two versions of the Internet Protocol, which are Internet Protocol Version 4 and Internet Protocol Version 6. Internet Protocol Version 6 (IPv6) replaces Internet Protocol Version 4 (IPv4) as an Internet Standard and is the next evolution of the Internet Protocol. IPv6 protocol has been improved in such a way as to enable a faster and safer data transfer. Example of IPv4 and IPv6 protocol implementation is shown in the program tool Cisco Packet Tracer

Sex-Related Differences in Oxidant and Antioxidant Profiles of Murine Kidney and Brain: A Focus on Sirt3-Mediated Regulation

Background: Sirt3 is a mitochondrial deacetylase with an important role in maintainance of cellular redox and metabolic homeostasis and mitochondrial function. As growing evidence support the existence of sex-specific responses to metabolic and oxidative stress, we aimed to investigate sex- and organ-specific effects of Sirt3 loss. Materials and methods: Expression of Sirt3, PGC-1a, CuZnSOD, MnSOD and Cat proteins in kidneys and brains of Sirt3-wild type (Sirt3 WT) and Sirt3-knockout (Sirt3 KO) mice was assessed by Western blotting. Protein carbonylation and lipid peroxidation levels were measured using ELISA and fluorometric assays, respectively. SOD and Cat activities were determined using standard enzymatic assays. Results: Significant sex- and organ- specific differences in response to Sirt3 loss were detected. Sirt3 knockout affected kidneys more than brain tissue, with females showing lower levels PC and LPO. In kidneys, female KO showed higher MnSOD, but lower CuZnSOD and Cat activity compared to males. In brains, WT females show higher activities of these enzymes than males, suggesting a sex-specific protection mechanism, but female KO brains show a larger decrease in these parameters. Conclusion: Our study provides comprehensive insights into the complex interplay of Sirt3, oxidative stress, and antioxidant defenses in murine kidney and brain. The observed differences between the two organs and the impact of sex highlight the need for studying Sirt3 function in diverse physiological contexts. The tissue-specific responses and sex-related variations underscore the importance of considering these factors in the development of therapeutic strategies targeting mitochondrial function and redox homeostasis

Structural Characterization of FAU Gene/Protein from Marine Sponge Suberites domuncula

Finkel-Biskis-Reilly murine sarcoma virus (FBR-MuSV) ubiquitously expressed (FAU) gene is down-regulated in human prostate, breast and ovarian cancers. Moreover, its dysregulation is associated with poor prognosis in breast cancer. Sponges (Porifera) are animals without tissues which branched off first from the common ancestor of all metazoans. A large majority of genes implicated in human cancers have their homologues in the sponge genome. Our study suggests that FAU gene from the sponge Suberites domuncula reflects characteristics of the FAU gene from the metazoan ancestor, which have changed only slightly during the course of animal evolution. We found pro-apoptotic activity of sponge FAU protein. The same as its human homologue, sponge FAU increases apoptosis in human HEK293T cells. This indicates that the biological functions of FAU, usually associated with “higher” metazoans, particularly in cancer etiology, possess a biochemical background established early in metazoan evolution. The ancestor of all animals possibly possessed FAU protein with the structure and function similar to evolutionarily more recent versions of the protein, even before the appearance of true tissues and the origin of tumors and metastasis. It provides an opportunity to use pre-bilaterian animals as a simpler model for studying complex interactions in human cancerogenesis
