In today’s business conditions, the internationalisation of business becomes an almost inevitable precondition for future growth and development of organisations. However, internationalisation of business usually requires organisations to implement some changes in the way they operated in the previous period. One of the areas that require some changes is the area of human resource management, too. Factors which require modifications in this system are related primarily to the legal regulations of other countries, but also to the characteristics of their national culture. The former influence comes from the fact that national culture exerts a powerful influence on the system of values, attitudes and behaviour of people in a particular country and, among the other things, on the preferences for policies and procedures in the field of human resources management. Starting from the above, this paper analyses the impact of certain dimensions of national culture on the preferred content of human resources management in organisations in certain countries. The aim of the paper is to provide the theoretical basis for organisations that internationalised their business, or intend to do so, to create system of human resource management in the entities abroad which, at least, will represent the balance between the system that is applied at headquarter and one that is preferred in entities abroad, in order to be effective.

Controversies in the Choice of the Optimal Therapeutic Approach to High Grade Intraepithelial Lesions (HSIL) of the Cervix
The incidence of preinvasive changes in the cervix is constantly rising. It is particularly alarming that there is a larger number of younger patients in whom some stage of these changes has been diagnosed or who had already received some type of treatment before. Technological development and improvement of various forms of treatment have lead to changes in the surgical approach to intraepithelial lesions of the cervix. The techniques that have been developed for this purpose, besides the coldknife conization, include loop excision, radio wave conization, laser conization and, recently, the conization by Harmonic scalpel. The question that inevitably arises is: Has the technological development led to more conservative approaches and improvement in the results of surgical treatment? This paper will try to partly answer this question and initiate some new questions and dilemmas. A comparative review of all of the abovementioned surgical techniques and their detailed analysis is expected to provide at least some answers to the controversial opinions for and against the new surgical procedures. The results of surgical treatments and their complications were analyzed with particular emphasis on the influence that these methods have on fertility. The conclusion is that there is no ideal surgical procedure which could replace and neglect the experience of a colposcopist. New surgical techniques have brought more surgical comfort and faster recovery but have not demonstrated significant change in the final results of treatment and recurrence.

Medicinal herbs and their mixtures, which are widely used for prevention and treatment of some disease, can also present health risks due to the presence of toxic metals such as Pb and Cd. The application of different agrotechnical practices during plant growing season, as well as the process of circulation of substances in nature, may be the cause of plant contamination.
The aim of this study was to determine the content of lead, cadmium and copper from soil which are bioavailable for absorption by plant, as well as the total content of these metals in some medicinal herbs that were cultivated in two different locations. The presence of these metals in the samples was detected using highly sensitive microanalytical technique potentiometric stripping analysis (PSA).
The mean value of lead total content in the analyzed samples of medicinal herbs Chamimillae flos, Urticae folium, Menthae folium, Altheae radix and Basilici herba, which were grown at the sites near the industrial zone, was about 1.55 μg/g, 1.82 μg/g, 1.90 μg/g, 1.99 μg/g and 2.74 μg/g, respectively. Contrary to this, the total content of this toxic metal in the analyzed plant samples grown on rural areas was detected only on some sites.
Based on the results of this study, it can be concluded that medicinal herbs contained a certain amount of lead and that its content varied depending on the location at which the plant species were grown as well as on plant affinity to certain metal. Cadmium and copper were not detected in the tested plant material.
An ethical dilemma is a situation of making a choice between two or more alternatives. An agent is in unpleasant and difficult situation because he/she often needs to make a choice between ethical and unethical alternatives, and when it comes to the ethical alternatives, he/she should choose the best one. Selection reflects to a large number of principals, so this situation causes conflicts between different levels of ethical dilemmas, but also the conflicts within the same level. These conflicts can be solved by applying the hierarchy and priority rules which are incorporated in the procedure and, in particular,in the strategy for solving the ethical dilemmas. Through many case studies this paper points out the importance of an ethical dilemma in making business decisions, the so-called business ethical dilemma. It is the result of the incompatibilities between altruism, egoism and the common good. Neglecting the need for establishing the compatibility not only creates an ethical dilemma, but it becomes deeper, which is firstly manifested through the loss of reputation of the company, then through decreasing the financial results, and, in the worst case, in closing the company. Therefore, an ethical dilemma must be continuously managed.
A rising number of patients are being treated for overdosing with new psychoactive substances (NPS) available at the illegal drug market in Serbia. The aim of this study was to report clinical and analytical experience of the National Poison Control Centre of Serbia (NPCC) with synthetic cannabinoids (SCs) and point to the NPS available at the illegal drug market in our country. From January 2013 to December 2016, 58 patients (aged between 14 and 25) were treated for the effects of synthetic cannabinoids at the NPCC. Tachycardia was established in 53, mydriasis in 31, somnolence, nausea, vomiting, and agitation in 16, dizziness in 10, disorientation in 9, dyspnoea and chest pain in 4, and loss of consciousness, pallor, paraesthesia, muscle twitches, and short-term memory impairment in 2 patients. After receiving symptomatic and supportive treatment in the emergency ward, all patients had fully recovered within 8 h and were discharged shortly afterwards. Another part of the study was focused on the analysis of the products known under their local street names as “Biljni tamjan” (herbal incense), “Beli slez”, and “Rainbow Special” and the analysis of urine sampled from the patients with gas chromatography - mass spectrometry and high performance liquid chromatography. The detected synthetic cannabinoids were AB-PINACA, JWH-018, JWH-122, JWH-210, 5F-AKB48, and MDMB-CHMICA in herbal products and AB-FUBINACA, AB-CHMINACA, and MDMB-CHMICA in the urine samples. Our findings have shown the great capacity of NPCC to I) monitor NPS abuse in Serbia, II) reliably detect SCs in illicit products and biological samples, and III) clinically manage the adverse effects in their users. Future commitments of the NPCC will include systematic collection of relevant data on SCs and their adverse effects, detection of changes in purity and composition of the controlled NPS-based products, and raising the public awareness of NPS to improve the effectiveness of the national Early Warning System.
