In recent years, the sharing economy has become a new buzzword, providing various business opportunities and challenges to conventional businesses. It is characterized by the transformation of conventional business sectors and many companies are already facing the pressure of adapting their operations to the changing conditions. Human resource management, especially when it comes to experts and knowledge workers, is among the affected business activities. In particular, due to the apparent high demand, this type of workforce has the opportunity to share services among many businesses. Therefore, human resource managers should tackle the issue of cultivating employee organizational identification to increase employee retention and achieve the desired performance. In this regard, this paper proposes a model that binds human resource management practices to employee organizational identification, innovative behaviour, knowledge sharing, and finally, employee job performance. The model is estimated using the survey method and structural equation modelling technique for data analysis. The results imply that selective recruiting, participation in decision-making, and rewarding contribute to employees' organizational identification, while training does not directly affect it. The findings, therefore, indicate that adequate human resource management practices, mainly through the simultaneous impact of the critical capabilities examined by this model, can serve as a foundation for business success in the sharing economy.

INTRODUCTION Breast cancer is the most common malignancy in women. Modern research attempts to investigate the relationship between psychoemotional parameters and the length of survival of breast cancer patients. Understanding the factors which affect a higher level of resilience can have important clinical implications and can represent a guiding principle for designing psychological interventions that would accelerate recovery and improve the quality of life of cancer patients. To explore the relationship between resilience and quality of life of women with breast cancer. METHODS The study was conducted at the Clinic of Oncology of the University Clinical Hospital Mostar, which included 60 subjects. Objective realization was achieved through using the socio-demographic questionnaire purposely made for this research, the quality of life questionnaire WHQOL-BREF and the psychological resilience questionnaire CD-RISC-25. RESULTS Subjects treated with radiotherapy achieved statistically significantly higher scores on subscales of the quality of life: mental health, social relations, and the environment. No statistically significant correlations were found between the level of resilience and results in the domains of quality of life. CONCLUSION There is not a statistically significant association between resilience levels and quality of life in patients with breast cancer.

In the logistics world, special attention should be given to warehousing systems, cost rationalization, and improvement of all the factors that affect efficiency and contribute to smooth functioning of logistics subsystems. In real time industrial practice, the issue of evaluating and selecting the most appropriate forklift involves a complex decision-making problem that should be formulated through an efficient analytical model. The forklifts efficiency plays a very important role in the company. The forklifts are being used on a daily basis and no logistical processes could be done without them. Therefore, it has been decided to determine their efficiency, which will contribute to the optimization of the process in this logistics subsystem. This study puts forward an integrated forklift selection model using Data Envelopment Analysis (DEA), Full Consistency Method (FUCOM) and Measurement Alternatives and Ranking According to the Compromise Solution (MARCOS) methods. Five input parameters (regular servicing costs, fuel costs, exceptional servicing costs, total number of all minor accidents and damage caused by forklifts) and one output parameter (number of operating hours) were first identified to assess efficiency of eight forklifts in a warehousing system of the Natron-Hayat company using the DEA model. This step allows sorting of efficient forklifts which are subsequently evaluated and ranked using FUCOM and MARCOS methods. A sensitivity analysis is also performed in order to check reliability and accuracy of the results. The findings of this research clearly show that the proposed decision-making model can significantly contribute to all spheres of business applications.

Introduction. Successful endodontic treatment depends upon the clinician's knowledge and ability to recognize and diagnose the presence of anatomical and morphological variations of the root and canal system. The aim of this study was to establish the number of roots and root canal configurations of the maxillary second premolar in the population of Bosnia and Herzegovina. Methods. The study sample was comprised of 150 maxillary second premolar teeth extracted for orthodontic or prosthetic reasons. Endodontic drills were used for trepanation of cavum dentis, and the number and patency of each root canal were determined by Kexpander # 15. Then, the samples were decalcified, made transparent and colored, to enable 3D viewing of the canal system. Decalcified teeth were observed from two projections (clinical and approximal) and analyzed in detail with a magnifying glass under 3 × and 5 × magnification in order to determine the number of roots, number of canals, root canal configuration using Vertucci's classification and number of anastomoses between canals. Statistical significance was obtained using Chi-square test. Results. The results obtained by decalcification of the teeth showed that, by radiographic analysis from the clinical projection, all the teeth had a single root. While, by the analysis from the approximal projection, 94.0% had one, 6.0% two roots. From the approximal projection, 70.7% with a single root canal and 29.3% with two root canals are visualized. The most common type of root canal configuration in the maxillary second premolars was Type I in both clinical (87.9%) and approximal projection (40.7%). Conclusion. These results emphasize the importance of knowing the variations in root canal morphology, because excluding the possibility of morphological variations can lead to failure of endodontic therapy

Introduction. Late metastases of malignant tumors in the temporal bone are very rare lesions. They can be asymptomatic for a long time, and usually manifest themselves in the form of hearing loss, dizziness, tinnitus, and paralysis of the facial nerve. Modern radiological diagnostics and explorative surgery with biopsy are essential for diagnosis. Case report. We present a rare and unusual case of a 66-year-old female patient with a facial nerve paralysis that appeared as the first sign of metastatic breast cancer in the temporal bone 10 years after treatment. A sudden hearing loss and dizziness occurred six months later and value of CA 15-3 was elevated. Scintigraphy pointed to susceptible metastatic deposits of the axial skeleton, without lesions in the temporal bone. Finally, repeated computerized tomography revealed osteolytic changes of the temporal bone six months after that. Immunohistochemical analysis of mastoid tissue samples confirmed that it was a breast cancer metastasis. One year after palliative radiotherapy and oral hormone therapy, a patient has a good general condition with better function of the facial nerve. Conclusion. A high degree of clinical suspicion sometimes requires repeated radiological diagnostics in order to detect osteolytic metastatic changes in the temporal bone, but also in other bone structures within the hematogenous dissemination of the malignant disease.

The morphological characteristics of elite basketball players are of great interest to some authors in order to define the best morphological profile for a particular playing position and different levels of competition. The aim of the research was to determine the differences in morphological characteristics in professional basketball players in relation to the playing position in different league competitions and to determine the relevance of these characteristics for success in the game. The survey included a sample of 773 elite basketball players competing in five different leagues in Europe. In our study, we found that centers are significantly taller and heavier than guards and forwards are. In addition to other components of basketball (technique, tactics, coach strategy), body height, body mass and body mass index play a major role in overall performance in a basketball game in all positions. The obtained data can help coaches in the scouting process in which leagues in Europe are played by players with certain morphological characteristics in relation to the playing position.
