Microbial communities seem to predominate in Antarctica, one of the planet’s most pristine places. Fungi are prevalent in Antarctica’s terrestrial ecosystems and may thrive in even the harshest conditions. Fungal species from the phyla Ascomycota, Basidiomycota, Zygomycota, Chytridiomycota, and Glomeromycota have been found in Antarctica’s microbial communities, as have others. Mycological research in Antarctica has recently concentrated on marine-associated fungi. There is still a lot to learn about the mycological richness and potential biotechnological applications of the austral ocean. Extremophile microbial communities predominate in a variety of Antarctica’s pristine settings. Microorganisms from Antarctica can be attractive sources of bioproducts with potential commercial applications, despite their ecological relevance. Seven distinct macroalgal species from maritime Antarctica were studied for their agarolytic and carrageenolytic capabilities in this study. 44 fungal isolates were recovered and identified by biological molecular methods as belonging to the genera Antarctomyces, Beauveria, Cladosporium, Coprinellus, Doratomyces, Leucosporidiella, Metschnikowia, Penicillium, and Pseudogymnoascus after a selective isolation process. The fungus with the greatest potential for agarolytic and carrageenolytic activity were protected by Rhodophyta macroalgae. Agarolytic and carrageenolytic activities were demonstrated by Penicillium chrysogenum, Penicillium sp., and Cladosporium sp. 2 concurrently. According to our findings, the Antarctic macroalgae harbor saprobe fungus, which produce enzymes that can destroy algal biomass and release vital nutrients into the Antarctic Ocean’s water supply. If further commercial techniques are needed to extract agar and carrageenan, or their derivatives, from Antarctic fungi, they could be beneficial.

‘’Design Balanced Scorecard for Maintenance Department in King Abd-ulziz Airport Hajj Terminals’’

:Abstract 

Since Kaplan and Norton introduced the Balanced scorecard (BSC) it had the attention of the whole world. This research aims to measure the effect of maintenance practices and activities on King Abd-AlAziz airport – Hajj Terminal operation process. Recently, the role of maintenance doesn’t end at repairing or fixing a machine or system, the maintenance these days playing an important strategic role in achieving business goals. This can be in terms of money (Financial), Process performance (Internal Perspective) Agents satisfaction (Customer Perspective), and Organizational capacity (Learning & Growth Perspective).

The Hajj terminal maintenance department aims to reach the maximum efficiency in terms of clients’ satisfactions, staff performance developments, cost reduction, and quality assurance. This research is trying to help the Hajj Terminal maintenance department ensure efficiency of processes and systems by improving KPIs to measure the effect of maintenance activities on its current operation processes.

The value of Balanced Scorecard is the main driver of getting the desired results that helps in exploring the effect of maintenance on terminal’s operations. The study creates a Balanced Scorecard to measure the performance of general maintenance practices, and establish KPIs to measure the department performance in all four parts of the Balanced Scorecard from row data.
