Newly discovered halos and outer features around southern planetary nebulae

We have used the SuperCOSMOS H-alpha Survey to look for faint outer structures such as halos, ansae and jets around known planetary nebulae across 4000 square degrees of the southern Milky Way. Our search will contribute to a more accurate census of these features in the Galactic PN population. Candidate common-envelope PNe have also been identified on the basis of their microstructures. We also intend to determine more reliable distances for these PNe, which should allow a much better statistical basis for the post-AGB total mass budget. Our survey offers fresh scope to address this important issue.Comment: 2 pages, 1 figure.

A retrospective study of surgical treatment of spinal injuries with rehabilitation program

Introduction: Traumatic injuries of the spinal column are among the most devastating injuries in orthopedics. The primary goals of rehabilitation of these injuries are prevention of secondary complications, maximizing physical functioning and reintegration into the community. Rehabilitation after spinal injury reqires multidisciplinary team approach. Team members include, but are not limited to, physical therapists, occupational therapists, nurses, psychologists, health care managers and social workers, with each member having role and responsibility in their area of expertise. This study aimed to determine the difference in the occurrence of spinal injuries according to gender, age, cause of injury, neurological phenomenon in injured patients, the treatment and physical procedures used in the early stages of rehabilitation.Methods: The study was conducted as a retrospective and comparative at the Department of Orthopedics and Traumatology of Clinical Center University of Sarajevo. Medical records of 100 patients, treated at from January 1st 2007 till June 30th 2008, were processed and data about outpatient protocols and surgery protocols analyzed.Results: The results obtained from the data showed greater proportion of women (56%) compared to men (44%). Most patients were in the age group between 41 and 60. Injuries were most often due to falls from height and make 32%, fall from a tree 25%, traffic accidents 12% (²=17.94, p=0.0061). 88% of patients were without neurologic events, while the neurological disturbances occurred 12% (χ²=3.397, p=0.3343). 56% of patients with spinal injuries were treated surgically, while 41% were treated conservatively (χ ²=7.264, p= 0.00153). 73% patient had physical therapy program of early rehabilitation exercises, with at least at least only a massage in 4% of patients X² = 6.573, p = 0.04270).Conclusion: The adoption of national protocols is necessary for future treatment of patients with spinal fractures

Production of Šar cheese: Development opportunity for Štrpce Municipality

As a result of the climate in which it is produced, as well as its recognizable taste and quality, the Šar cheese is a high demand product on the market of Kosovo and Metohija. The authors will, based on the research presented in this paper, give an overview of the production and the main carriers of the Šar cheese production. It will also present how Šar cheese production may be used in helping people survive in Sirinićka Župa. This paper would also, through direct surveys, observe perceptions and attitudes of the inhabitants of this region and provide practical guidelines on the production of the Šar cheese as development potential of the municipality of Štrpce, and recommend further agricultural reforms and tourist capacities of this region

Model-driven development of Data Vault based data warehouses.

U tezi je razmatrano više problema vezanih za projektovanje i razvoj skladišta podataka, kao što su: - neusaglašenost skladišta podataka sa izvorima podataka, nastala kao rezultat permanentnih promena strukture izvora, - nekompletnost podataka u skladištu podataka, - heterogenost modela izvora i njihova semantička neusaglašenost - nepostojanje standardnog konceptualnog modela i modela strukture skladišta podataka...Several issues, related to the design and development of data warehouses, are analyzed in this thesis: - inconsistency between the data warehouse and data sources due to the permanent changes in the structure of the data sources, - incompleteness of the stored data, - heterogeneity of data source models and their semantic inconsistency, - absence of standardized conceptual or structural data warehouse models..

Radio Planetary Nebulae in the Small Magellanic Cloud

We present ten new radio continuum (RC) detections at catalogued planetary nebula (PN) positions in the Small Magellanic Cloud (SMC): SMPS6, LIN 41, LIN 142, SMP S13, SMP S14, SMP S16, J18, SMP S18, SMP S19 and SMP S22. Additionally, six SMC radio PNe previously detected, LIN 45, SMP S11, SMPS17, LIN321, LIN339 and SMPS24 are also investigated (re-observed) here making up a population of 16 radio detections of catalogued PNe in the SMC. These 16 radio detections represent ~15 % of the total catalogued PN population in the SMC. We show that six of these objects have characteristics that suggest that they are PN mimics: LIN 41, LIN 45, SMP S11, LIN 142, LIN 321 and LIN 339. We also present our results for the surface brightness - PN radius relation ({\Sigma}-D) of the SMC radio PN population. These are consistent with previous SMC and LMC PN measurements of the ({\Sigma}-D) relation.Comment: Accepted for publication in Astrophysics and Space Scienc

KORELACIJA STILOVA LIDERSTVA I ZADRŽAVANJA ZAPOSLENIH

Liderstvo je u velikoj mjeri povezano s motivacijom i kao takvo utiče na fluktuaciju i zadržavanje zaposlenih. Lider uspostavlja planove, ima sposobnost predviđanja i dijagnosticiranja posljedica budućih događanja, te rješava kompleksna pitanja motivacije zaposlenih. Zadržavanje zaposlenih podrazumijeva različite akcije i strategije koje kompanija razvija kako bi zadržala zaposlene unutar kompanije. Unutar ovih strategija, liderstvo se smatra jednim od glavnih faktora koji mogu promovirati dugoročno zadržavanje. Istraživanje Work Institute iz 2020. godine pokazalo je da je ponašanje lidera na drugom mjestu razloga napuštanja organizacije. Pitanje zadržavanja i lojalnosti zaposlenih ne odnosi se samo na primjenu adekvatnih motivacionih tehnika, već i na uklanjanje demotivatora, kao što su stilovi liderstva koji ne omogućavaju dostizanje kompanijskih ciljeva aktiviranjem intrinzične i ekstrinzične motivacije zaposlenih. Ovaj rad analizira glavna obilježja transformacijskog i transakcijskog liderstva. Istraživanjem u odabranoj kompaniji ispituju se stavovi zaposlenih i menadžera u pogledu stila liderstva koji se primjenjuje, kao i glavnih faktora fluktuacije. Primjenom Pearsonovog koeficijenta korelacije, testira se hipoteza da transformacijsko liderstvo ima pozitivan korelacioni odnos sa zadržavanjem zaposlenih
