The aim of this paper is to analyze the safety of forklift brakes. The research methodology used to analyze forklift brake safety is presented using the checklist descriptive method. The study was conducted on 127 forklifts with an average age of 15 years, where it was found that about 10% of the forklifts did not have a proper parking brake and that about 2% of the forklifts had defective service brakes. Finally, the results obtained from the research on brake safety have been discussed and further research has been proposed.

OBJECTIVE To describe the technical nuances of multimodal transseptal-transsphenoid surgery for pituitary tumors using a combination of microneurosurgery, neuroendoscopy, and electromagnetic neuronavigation. MATERIALS AND METHODS A transnasal approach to the sella is performed endoscopically and widely exposed by an otolaryngologic surgeon. Surgery is next performed by the neurosurgeon with microscope and neuronavigation for microsurgical resection of pituitary tumors. Neuroendoscope is also used at the end of surgery to confirm tumor resection and inspect operative site. During surgery, the patient's head, angle and height of the microscope, and position of the table are repositionable to allow for multiple angle views. Abdominal fat harvested prior to the procedure is used to ensure cerebrospinal fluid seal. RESULTS The senior author (KIA) has used the combined approach with 84 consecutive patients. Radical resection was achieved in 66 patients, subtotal in 11, and partial in 7. There were no perioperative complications. Six patients experienced postoperative transient diabetes insipidus. The pituitary gland and stalk were preserved in all cases. Visual symptoms were improved in 78% and endocrinological symptoms in 56% of cases. CONCLUSION This combined approach is safe and effective. It increases the efficacy and radicality of surgical resection, helps to preserve the pituitary gland, and improves and resolves preoperatively altered patient hormonal function and impaired vision. It also reduces complications, provides less postoperative pain and discomfort, reduces the surgery time, and enables a shorter hospital-stay.

On September 9-12, 2019, I traveled to Beijing, China for the World Congress of Neurosurgery. I was eager to attend the biggest event of my profession for two reasons. One was my nomination for second vice-president of the World Federation of Neurosurgical Societies (WFNS). The second reason was to learn about Chinese culture for the first time in my life. I was honored to be elected for an officer position of the WFNS and I tremendously enjoyed the grandiosity of the Great Wall of China (Figure 1), the Forbidden City, and Summer Palace; I also enjoyed trying authentic Chinese food.

As a consequence of the measures taken to remedy the medical problem, there may be a bigger one economically, all over the world. The paper analyzes the consequences of the current economic crisis caused by the COVID-19 virus pandemic. The key economic consequences of the pandemic for companies but also for the economy have been identified. Entrepreneurs, small and medium enterprises, with the smallest liquidity stocks, are expected to feel the greatest consequences of the economic crisis. Taught by the failures of the Great Depression and the relative successes of the crisis in 2008, governments have already announced and launched massive programs to help businesses. At this moment, the supply of liquidity of deficient economic entities is a critical issue. The previous crisis showed that governments have tried and tested mechanisms for supplying liquidity to the financial sector, but transmission mechanisms to end-users were the Achilles' heel of the mechanism. We believe that success in finding adequate channels for the transfer of liquidity to economic entities with a liquidity deficit will be crucial for the character, length, and depth of the crisis. The paper offers a number of proposals for key necessary measures at the state level to overcome the observed economic disruptions. One of them is the request of the regulator, the other is the reaction of the state, but an important part must also come from the company. In addition, the research conducted by the questionnaire method for joint-stock companies from the Western Balkans resulted in a set of measures that serve as a basis for determining the gap in the required and current set of measures taken at the level of an individual organization.The aim of this paper is to point out that in the short term it is possible to stabilize the system through the application of macroeconomic and microeconomic measures.
