The legal regime of international humanitarian assistance provided during armed conflicts is based on several general legal principles. They are guiding principles that apply in all circumstances and situations, regardless of the nature of the armed conflict. The first principle entails that the state has primary responsibility to ensure that the basic needs of population under its jurisdiction are met during the armed conflict. The second principle, closely related to the first one, is the principle that third countries and international humanitarian organizations may offer assistance if a party to the conflict fails to undertake its duty to provide supplies necessary for the survival of the population. The next principles calls for the consent of all concerned parties in the provision of humanitarian assistance, as well as the duty of the parties to the conflict and all third countries to approve and facilitate the unimpeded passage of aid. The last principle is that staff involved in relief operations must be respected and protected. In addition to these general legal principles, international humanitarian assistance is regulated by a dozen of special rules covering various aspects of providing international humanitarian assistance during armed conflict. These rules are the result of a compromise between efforts to provide the vulnerable population with the necessities of life and a demand to protect the sovereignty of all parties to the conflict, but particularly of the state in which the aid is being sent. There is a difference between the rules governing humanitarian aid operations in international armed conflicts and the rules applicable in non-international conflicts. The first group of rules is far more numerous; they regulate in detail the issues related to relief actions, including the conditions for passage, delivery and distribution of consignments, the types of goods and services that can be sent, the category of persons who they are intended for, the position of the personnel engaged in these operations, and the technical conditions for implementing these rules. As regards non-international armed conflicts, the rules on humanitarian assistance are fewer, shorter and more general. These scarce rules are sometimes vague, and they mainly come down to the principle of humane treatment and the right of international humanitarian organizations to offer their assistance. Given that non international conflicts are the predominant form of armed conflict today, there is a strong tendency to extend the application of codified rules of international law governing the provision of humanitarian assistance to these conflicts. The practice of respecting almost all codified rules governing the provision of humanitarian assistance in modern armed conflicts and its wide acceptance by states and other participants confirms that the rules of customary International Humanitarian Law created in this area are applicable in both international and non-international armed conflicts.

The reimbursement of the costs and expenses incurred by the applicant in the proceedings is the one form of just satisfaction which is not explicitly provided for in Article 41 of the ECHR. The costs and expenses incurred in order to prevent a violation of the Convention or to remedy the consequences of a violation thereof shall be reimbursed. They cannot be covered by the mere statement that the injury itself constitutes just satisfaction without awarding a monetary sum. The award relates both to the costs incurred by the applicant before the domestic authorities and in the proceedings before the ECtHR itself. In terms of costs payment, the applicants are at a disadvantage as compared to the States. In order to mitigate this inequality, free legal aid has been established. It is granted by the ECtHR upon the applicant's written request or on its own motion. Legal aid shall be given if it is necessary for the proper conduct of the proceedings and if the applicant has insufficient means to meet all or part of the costs entailed. Free legal aid covers the fees of the applicant's legal representatives as well as other expenses incurred by the applicant and related to the proceedings. The Convention does not provide the criteria for affording costs and expenses, but the issue is settled by the Court in each particular case. Through long-standing and extensive case law, a four-part test for awarding costs and expenses has been established. According to that test, the costs must cumulatively fulfill the following conditions in order to be reimbursed: they were incurred in connection with a violation of the Convention; they were actually incurred; they are necessary; and they are reasonable as to quantum. As regards the procedure, the Court does not award the costs on its own motion or in excess of the amount claimed by the applicant. A claim for reimbursement can be made only by the plaintiff in his own name and within the time limit set by the Court. The request must be accompanied by all the necessary evidence to show that the costs were actually incurred. The Court may decide on the submitted request in the principal judgment or postpone this issue and settle it in a separate judgment. If the Court has accepted the claim, it awards in the judgment the lump sum covering all recognized costs. The state must pay the reimbursement within three months and interest will accrue after the expiry of that period.

European Union ,asylum ,Directive 2013/32/EU ,asylum applicant ,Dublin rules ,Law - Abstract
Directive 2013/32/EU established the common standards which the EU Member States are obliged to incorporate into their national legislations in order to regulate the procedure for deciding on asylum applications. Asylum proceedings are to be carried out by national authorities but states are obliged to comply with the standards set out in this Directive. The asylum procedure is initiated upon the request of an interested party and its aim is to examine whether a third-country national or a stateless person has met the requirements for obtaining a refugee status. Before examining the justifiability of the asylum application, it is essential to determine which EU Member State is responsible for examining the application, which is established by applying the Dublin rules. If it is established that the state of the applicant's current location is not the state responsible for examining the asylum application, the applicant will be transferred to the respective state. Then, the responsible state is obliged to institute the first instance procedure and examine the submitted application within the prescribed time limits. The examination is carried out in a regular court proceeding, unless there are reasons for instituting a special proceeding (a priority procedure, an admissibility procedure, an accelerated procedure, and a border procedure). Under this Directive, the applicant is guaranteed the right to remain in the territory of the deciding EU Member State, as long as the final decision at first instance is pending, and some other procedural guarantees aimed at ensuring that the decision on asylum has been rendered by observing the rules of fair proceedings. On the other hand, the applicant has certain obligations, the most important of which are the obligations to appear before the competent state authority, to submit the available documents, to agree to being photographed and fingerprinted, etc. If dissatisfied with the first instance decision, applicants may challenge the decision by filing an appeal with the competent national court. During the appeal proceedings, they have the right to remain in the territory of the EU Member States, except in cases involving a number of explicitly prescribed situations. If the asylum application is accepted by the final decision of the competent authority, the person acquires the legal status of a refugee and all the rights arising from that status. If the asylum application is denied, the person is obliged to leave the territory of that EU Member State.

Once the Schengen Agreement came into force, there was a need to adopt a framework of common rules which would regulate some asylum-related issues in the newly-created Schengen area without internal borders. The first step in that course was made in 1990 by adoption of the Convention Determining the State Responsible for Examining Applications for Asylum, as an instrument of classical intergovernmental cooperation. Whereas the Maastricht Treaty did not bring any significant developments in the field of asylum policy, the Amsterdam Treaty was a significant turning point in this field. Under this Treaty, the asylum policy became part of the first pillar of EU, which implies that the Brussels institutions were given the authority to embark on the process of establishing the Common European Asylum System (CEAS). In the first phase of development of the CEAS system (1999-2005), the EU adopted a number of binding Community acts which laid down minimum asylum standards. Drawing upon the shortcomings observed during the implementation of the adopted directives and regulations, the EU embarked on their review and recast. The instruments adopted in the second phase of developing the CEAS system (2006-2013) were much more detailed and advanced in terms of regulating both the procedure for providing international protection and the contents of that protection. However, such a concept of the CEAS has turned out to be quite ineffective in the circumstances of mass migrant flows. For this reason, in 2015, the EU has adopted a range of measures aimed at eliminating the observed shortcomings.

Axial magnetic force calculation between two ring permanent magnets is presented in the paper. One magnet is magnetized in radial direction while the other one is magnetized in axial direction. Configuration like this one resembles the one passive magnetic bearing has. Force calculation is performed using semi analytical approach based on fictitious magnetization charges and discretization technique. For comparison purposes, and in order to check preciseness of the method applied, Finite Element Method (FEM) results were used. [Projekat Ministarstva nauke Republike Srbije, br. TR 33008]

In this paper an approach to efficient computation of radiation pattern in FDTD simulation environment is presented. A necessary large distance from the radiating object is achieved by multigrid space discretization with unilaterally connected subdomains. A numerical dispersion is reduced using more general complex-envelope finite difference time domain (CE-FDTD) formulation and high order accuracy FDTD schemes where possible. In order to examine how much the introduced algorithm complexity and increased demands concerning computational power and memory are justified by the gain in accuracy, several different scenarios were considered.

9. Proposals for regulating future humanitarian interventions

Although the legality of approved humanitarian intervention is undisputable in the positive international law, this legal institute should be further regulated in order to remove certain legal ambiguity and difficulties in its application. The future regulation of humanitarian intervention may be carried out in one of the three ways: by adopting a special international treaty, by entering amendments in the UN Charter, or by embarking on the factual revision of the UN Charter. Due to the limiting effects of Article 103 of the UN Charter as well as the problematic status of UN member states which would not ratify the international agreements on humanitarian intervention, the regulation of future humanitarian intervention seems to be the least likely option. Formal revision of the UN Charter is not a viable option either because, thus far, the major world powers have been against introducing any substantial changes to this treaty. For this reason, the factual revision of the UN Charter is currently the most appropriate way of regulating future humanitarian interventions. When it comes to substantive rules governing humanitarian intervention, it is necessary to focus on the problem of humanitarian intervention decision-making as well as on the conditions and criteria for the approval and carrying out a humanitarian intervention. The UN Security Council must retain the right to decide on approving such an intervention but it is also necessary to establish an independent expert body whose task would be to determine the presence of serious and mass violations of human rights in a specific country and notify the Security Council about such occurrences. The specification of conditions and criteria for undertaking a humanitarian intervention should strengthen its legitimacy and prevent unreasonable disruption of states' territorial integrity and political independence.

One of the significant competences of the European Court of Justice is to issue a preliminary ruling on an issue which has been referred to this Court by the national courts of the EU Member States. In this procedure, the national courts are provided the necessary explanation on the applicable EU law, either through by interpreting some legal provisions or by assessing the validity of a legal act adopted by the EU institutions. The preliminary ruling of the Court of Justice is binding for the national court which referred the issue to the Court. The decision is also binding for all national courts which have jurisdiction to decide on legal remedies in this matter. On the other hand, the effect of the preliminary ruling on other national courts is not quite clear. In other words, there is a dilemma as to whether the preliminary ruling on a disputed issue posed in one proceeding is binding for all other courts, which have not been actually involved in this particular proceeding. As for the temporal effect of a preliminary ruling, there is a general rule that the Court's preliminary ruling has a retroactive effect. However, in some situation, the Court of Justice may limit the retroactive effect of its rulings if their ex tunc application is incompatible with the principle of legal certainty.

international humanitarian law ,protection of the environment ,international environmental law ,international treaties ,international customary law ,soft law ,Law - Abstract
The article deals with the problem of environment protection during armed conflicts. The authors primarily focus on examining the possibility of applying international environmental law in armed conflicts. In the first part of the paper, the authors provide an overview of relevant rules of international humanitarian law which are important for environment protection and contained in different sources of law governing this area (international treaties, international customs and general principles). In this part, the authors point out to the weaknesses and shortcomings of the IHL environmental provisions, including both the traditional rules which have an indirect effect on environment protection and the contemporary rules which in most cases directly protect the environment. The second part of the article deals with the rules of international environmental law applicable in armed conflicts. The authors first examine the possibility of applying multilateral environmental treaties in armed conflicts. In that context, the authors point out to different types of such treaties, with specific reference to the treaties which do not contain provisions on their applicability during armed conflicts. Further on, the authors analyze the application of customary environmental rules in armed conflicts. These rules are considerably less important than international treaties and they commonly comprise a few general principles which may be considered nowadays as the rules of customary law. Finally, the authors explore the possibility of applying the rules of environmental soft law, such as the rules contained in different declarations and resolutions adopted at international conferences or within the framework of international organizations.

In International law, the status of persons with mental disabilities is regulated within the framework on the protection of persons with disabilities. Their rights are protected not only by international treaties comprising legal provisions of binding character for the parties but also by means of the so-called "soft law" comprising international documents which are not legally binding. Most of the general and subject specific treaties on human rights do not explicitly deal with the status of persons with disabilities. Only recently have some treaties been made containing legal provisions on special protection of persons with disabilities. The most important treaty of this kind is the UN Convention on the Rights of Persons with Disabilities, adopted in the year 2006. The protection of such persons is regulated in much more detail by "soft law" which includes a number of documents adopted by the UN, the Council of Europe and the European Union. Although most of these documents primarily pertain to the rights and the status of persons with disabilities, there are a few that exclusively deal with the protection of persons with mental disorder.

Experimental evaluation of the measurement results based on FSM (Frequency Shift Method) concept in the non-conventional FOP (Fall-of-Potential) measuring scheme, for different angles between the test conductors, is presented in this paper. As it is well known, the optimal angle between the test conductors is θ = 90°. However, in practice, most often because of the physical obstacles in the surround substation, this condition cannot be provided. We have experimentally determined that the angle between the test conductors must be less than 60° relative to the optimal angle θ. In that case the corresponding measurement error is less than 3%.

The condition of thesubstationgrounding grid is vital for the safety of the people. Inadequate grounding may cause failures in majorsubstation's equipment, as well as in control, metering and telecommunication equipment. Therefore, it is necessary to clearly identify damaged elements on grounding grid. This paper presents an approach to test the integrity of the grounding grid in a general framework of IEEE Std. 81-2012. More precisely, in order to locate damaged grounding riser(s) and/or grounding grid conductor(s), this paper is focused on novel unambiguous criteria for post-processing of raw-data collected from the measurements. In order to avoid the effect of power frequency interference on the measurement, we use DC test current of 100A. The field test is described and discussed in details. The outcome of field test clearly shows the validity and feasibility of the proposed approach.

GPS device, longitudinal speed, vehicle drag, estimation, bicycle electrification - Abstract
When designing an electric motor drive for a conversion of bicycle to an electric vehicle it is obligatory to determine the required power of the electric motor and the energy of a battery pack. By using a classical method, drive requirements can be established with speed and torque measurement on the drive wheel of the vehicle using a torque meter. The given traction profile is used for the design of the drive. This paper describes the method for estimation of power and required energy of vehicle only by means of global positioning system (GPS). When selecting a GPS device, it is necessary to take the resolution of the device and accuracy of vehicle speed and altitude into account. Using the measured track (speed and altitude profile) and the drag model of the vehicle it is possible to calculate both power that the vehicle develops, and energy consumed for a certain distance. The GPS device measurements, selection of electric drive, bicycle electrification and analysis of processed KTM Knoxville electric bicycle is presented.

Cable termination and joint, stress grading, Hybrid Boundary Elements Method, High frequency, Deflector - Abstract
Power cables and application of various power electronic devices, such as voltage source converters play very important role in the transmission and converting green energy. In these systems high frequency harmonics of voltages and currents appear, stressing additionally the insulation of the cables and their joints and terminations. The analysis of basic kinds of electric stress grading in the cable termination has been particularly made in high frequency range. Possible insulation failure can occur because of lower breakdown strength of dielectric material under HF voltage and appearance of hot-spot due to distortion of electric field distribution amid resonance. The Hybrid boundary element method (HBEM) can be successfully applied for analysis of such structures. Combined with theoretical analysis, it is possible to calculate right position of hot-spots because of the existence of a harmonics. The practical solution is application of geometric stress grading method, which is not susceptible in HF range. The total losses effects in HF range generate more intensive heat dissipation. The distribution of the thermal field in cable accessories was also determined. The experiments show a good agreement with the numerical results.

This paper describes a modification of the Hybrid Boundary Element Method (HBEM) for electrostatic problems solving. Such improved method is applied for transmission lines analyses. By taking a quasi-static TEM approach, the Hybrid Boundary Element Method is applied to determine the effective relative permittivity and the characteristic impedance of different stripline structures. Comparisons with already published numerical results and software simulation have been also performed with an aim to test the validity of the proposed approach. A close results match can be noticed. The main novelties of the proposed HBEM modification are better accuracy and ability to determine the polarization charges distribution on the separating surface between a strip and a dielectric layer. This was not possible before, using the previous version of the method. [ABSTRACT FROM AUTHOR]

- Abstract
In this PhD thesis two-channel QMF IIR filter banks have been discussed. As a part of this research, direct synthesis of a new IIR filter class, as a lowpass protoype function which satisfies condition for complementary decomposition, has been proposed. Since attenuation characteristic of the new filter class lies in the area between the Butterworth’s and the Elliptic’s attenuation characteristics of the same order, new class has been referred to as Transitional Butter-Elliptic filters. Transfer function of the the lowpass prototype function was separated into two allpass filters by complementary decomposition. Then, lowpass and highpass filters, as power symmetric filter pair, are obtained using those allpass filters. The main advantage of complementary IIR filters based on parallel connection of two allpass filters, is its smaller sensitivity to digital word length change compared to standard filters and low-cost implementation since the same hardware is used for the lowpass and the highpass transfer function. Within the analysis of the new filter class, transfer functions of the odd order with one, two, three and four extremal values of attenuation characteristics in the passband and in the stopband, has been discussed. All types of Transitional filters have been compared with the Butterworth’s and the Elliptic’s filters of the same order. It is shown that in comparison with Butterworth filter, the Transitional filter has better selectivity but lower selectivity than Elliptic filter. However, the proposed new filter class has pure imaginary poles and accuracy in complementary decomposition is at very high level, which the Elliptic filter cannot achieve. Also, the practical realization of the new filter class is easier than for the Elliptic filter since the new class has conjugate-complex zeros on the unit circle and one multiple zero at z = −1. Further, poles and zeros of the Elliptic filter are accumulated near the passband edge and the distance between them dec

A new numerical procedure for optimization of the coaxial ring conductor’s system for electrostatic shielding is developed in the paper. The optimization of functional, consisting of electrostatic energy density and system of equations that is derived from the equipotential character of conductor’s system, is used. By minimizing this functional, the system of nonlinear equations is obtained and then numerically solved. The energy density is defined in the points along the axis of the system. A few numerical examples are given.

Measuring of above ground permanent connections electrical resistance may be a difficult task to achieve, when the high-voltage power facility is in normal operating condition. In order to improve the susceptibility to the power frequency interference in the measurements, we present a measurement approach, which utilizes the DC test current of 100 A through the grounding grid connections to structures or equipment. The main advantage of the proposed approach is reflected in the fact that we create an algorithm for detection of above ground permanent connection with high value of electrical resistance. The criteria for evaluation of poor connection are empirically derived. Field test results justify and validate the proposed approach., ISBN 978-86-7877-027-2

grounding system ,electromagnetic interference ,spectral analysis - Abstract
The measurements which are related to the high-voltage substation grounding system are inevitably affected by electromagnetic interference caused by power frequency and its harmonics. In order to avoid the problem due to interferers, traditional measurements are based on heavy test current injection. In most cases this approach is impractical. In this paper, we evaluate experimentally an effective method for eliminating the effect of interference at power frequency. This approach based on test signal at three frequencies, is slightly different from the power frequency. For that matter, there are two problems: 1. How to choose adequate set of test frequencies, and 2. How to determine optimal intensity of the test current. In this paper, we solve the mentioned problems based on the results of extensive field test measurements at substations 110/X kV, 220/X kV and 400/X kV. We show that the set of suitable test frequencies are: 40 Hz, 60 Hz and 75 Hz. Also shown is a method for finding the optimal intensity of the test current.

The measurement of grounding system impedance of an energized substation is usually required. Consequently, the power system frequency interference and harmonic frequencies may adversely affect the measurement. In order to improve the signal-to-interference ratio, we can increase the intensity of the test current or the test current frequency should be slightly differ-ent from the power system frequency. In the latter case, so called Frequency Shift Method (FSM), the intensity of test current may be relatively low. In this paper, we empirically examine the suffi-cient intensity of the test current. The corresponding field test in the 220/110/10 kV substation is described

The measurement of grounding system impedance may be affected by power system frequency interference and its harmonics. The Shifted Frequency Method (SFM) is potentially insensitive to the electromagnetic interference. In this paper, we evaluate this method in the hydroelectric power plant for two different load conditions of the connected overhead power lines. Presented field tests results further validate and justify the SFM method.

Non-pecuniary damages are a form of just satisfaction that the ECtHR may award if a violation of protected rights is found. These damages can be claimed by individuals, groups of persons, non-governmental organizations and states, whereby the awarded amount must be distributed to individual victims. However, for the Court to award compensation for non-pecuniary damage, several requirements must be met. The Court has awarded compensation for non-pecuniary damage on several grounds, such as pain, stress, anxiety, frustration, embarrassment, humiliation, and loss of reputation. Unfortunately, the criteria for determining the amounts of compensation for moral damage are still not clear and precise, so they have been determined by the Court on an equitable basis, taking into account its case-law standards.

MAGNETISM - Abstract
Magnetic force between U-shaped permanent magnet and linear infinite plane is determined in the paper. Two different cross-sections (circular and rectangular cross section) are considered in the paper in order to analyse their effects on the attraction force. It is confirmed that results obtained using presented method, in case of rectangular cross section, enable more rapid parametric studies of the attraction force, relative to dimensions and spacing.

- Abstract
The grounding system has an important role to maintain safe and reliable operation of highvoltage (HV) power facility (usually substation). The main task of a grounding system is to discharge maximum ground fault current expected into the soil, without exceeding safety limits for touch and step voltages within the substation and the surrounding area. It is desirable that the substation grounding provides a near zero resistance to remote earth. The prevailing practice is to install a grounding grid of horizontal ground electrodes (buried bare copper conductors) supplemented by a number of vertical ground rods connected to the grid, and by a number of equipment grounding mats and interconnecting cables. The grounding grid provides a common ground for the electrical equipment and for all metallic structures at the substation. It also limits the surface potential gradient. Grounding is traditionally modeled as a pure resistance. This is a good approximation at low frequencies, but as the frequency gets higher, inductance starts to play an important role. National and international standards give detailed guidelines for grounding system design, as well as for testing, under power frequency conditions, but only limited recommendations for high frequency and transient conditions are available. The main performance metrics of the grounding system are: grounding grid integrity, grounding system impedance, and touch and step voltage. The performance metrics should be periodically tested. The goal is to perform the test when the substation is in-service (to avoid interruption of service and costly downtime). Due to conductive interference in the grounding system (usually several amperes, up to about 15 A), caused by power frequency, its harmonics and background noise, the active HV substation is an extremely challenging environment for the measurement on grounding system. This is further compounded by the impact of very low impedance of the grounding system (typically less tha

- Abstract
The area of freedom, security and justice was established by the EU constituent treaties and it was set as a special objective of the European integration. This area has undergone dynamic stages of institutional and normative development to become an integral part of the EU today. It would be difficult to imagine the existence of the EU without it. Historical development of the Union showed that protection of the basic citizens‘ values is not possible without clearly defined policies and joint cooperation of the Member States in the area of internal affairs and judiciary. Sensitivity of this cooperation stems from transferring national responsibilities to supranational level in the areas that are the core of every state‘s sovereignty. Use of legal force apparatus and criminal law jurisdiction have been until recently a national issue, and the Member States have been keeping this area from breakthrough of international or, in the case of EU, deeper mutual cooperation at any cost. The area of freedom, security and justice consists of three areas. The European area of freedom and free movement of people has been created by the Single Market. In addition to the advantages for the Union‘s citizens and citizens of third countries, the Single Market has enabled expansion and transfer of criminal activity in the area without internal borders. The European area of security entails police cooperation of the Member States on preserving security within the area of freedom and free movement of people. The cooperation in this area is the basis for efficient joint preventive and repressive action on fighting crime, especially serious crime with cross-border dimension. The European area of justice consists of elements of criminal law and civil law cooperation of the Member States. Joint definitions of criminal offences and sanctions, mutual recognition of verdicts and guaranteeing the rights of suspects or accused in a criminal procedure are crucial issues of the cooperation that h

A system which contains two or more multilayer solenoid coils is a kernel of step motors. There is a 'strong' permanent magnet inside the solenoid coils. The magnet is being moved by the action of electromagnetic field force, which is caused by the coils. Numerical calculations combined with analytical expressions for electromagnetic field strength that exists in the core of step motors, magnetic flux and force on moving magnet, which transforms translational motion into rotational motion, are given in this paper. By comparing with an experimental result, it will be shown that the proposed technique is accurate and effective in calculating both electromagnetic field distribution and strike force of permanent magnet.

Convention on the Law of the Sea ,Convention relative to the Laying of Automatic Sub ,naval mines ,armed conflict - Abstract
Naval mines are explosive warfare devices which are activated by contact or by proximity of a boat or a submarine. These mines can be used in times of peace and during armed conflicts. The rules on the use of naval mines in times of peace are explicitly provided in the 1982 Convention on the Law of the Sea, as well as in international customary law. Coastal states are allowed to lay mines in their internal waters, territorial sea and archipelagic sea. In case of laying mines in their territorial sea, a coastal state is obliged to give notice to all other coastal states on the location of the emplaced mines and the state shall not suspend the right of innocent passage to foreign ships. In case of laying mines in the archipelagic sea, mines may not be laid in archipelagic sea lanes. The rules on laying mines on the high seas are not so clear but there is a prevailing opinion that mining is prohibited of these areas. The emplacement of mines during armed conflicts is regulated by the 1907 Convention relative to the Laying of Automatic Submarine Contact Mines, as well as by some provisions contained in the 1907 Convention concerning the Rights and Duties of Neutral Powers in Naval War. These conventions contain fairly clear rules on the mining in the naval armed conflicts but there is a dilemma whether these rules apply to new types of naval mines. In order to promote the adoption of new rules in this area, a group of experts made San Remo Manual on International Law Applicable to Armed Conflict at Sea (1994), which includes 13 paragraphs on naval mines.

Due to serious humanitarian problems caused by landmines, the international community has adopted three international treaties containing a number of prohibitions and restrictions on this kind of conventional weapons. The use of landmines was first restricted by Protocol II on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices (1980), which was subsequently amended in 1996. The 1980 Protocol adopted the same restrictions for anti-personnel and anti-tank mines but, in practice, these restrictions proved to be inadequate for eliminating harmful humanitarian effects. The 1996 Amended Protocol brought some improvements in comparison to the initial version of this treaty. This Protocol contains special more stringent provisions on the use of anti-personnel mines, and brings additional restrictions on the use of remotely delivered mines. It has also significantly improved the rules on recording minefields for a later removal of landmines. The largest step forward was made by the adoption of the Ottawa Convention on the anti-personnel mines which explicitly prohibits the use of these mines, their stockpiling, production and transfer, and imposes the obligation to destroy the existent stocks.

In international humanitarian law there are only a few rules which directly protect the environment. These rules are contained in the Additional Protocol I of 1977, the ENMOD Convention of 1976 and the Convention on Conventional Weapons, as well as in its Protocol III on Prohibitions or Restrictions on the Use of Incendiary Weapons. In addition, there are a number of rules within this branch of law which indirectly protect the environment during armed conflicts. The most important among them are the general principles of international humanitarian law (military necessity, proportionality and distinction) which are applicable to all states due to their character of being customary law. Moreover, some treaty provisions provide for indirect environment protection, and they are contained in the Hague Regulations of 1907, the Fourth Geneva Convention of 1949 relative to the Protection of Civilians and the Additional Protocol I.

Every year, a large number of journalists are killed or injured in line of professional duty or on account of the results of their investigative journalism, particularly in the course of armed conflicts. Unfortunately, there is no single document in international law which would embody specific rules on the protection of journalists. Instead, the protection of journalists in international law is exercised on the basis of general rules contained in human rights treaties and special provisions of international humanitarian law. In the past period, there have been several attempts to adopt a special treaty on the protection of journalists engaged in dangerous missions. The first efforts came from some professional journalists’ associations at the end of the 1960s but the proposed drafts did not obtain necessary state support. Given the frequency of casualties involving journalists, the United Nations also engaged in improving the international protection of journalists. The UN General Assembly requested from the Human Rights Commission to draft a convention providing for the protection of journalists on dangerous missions. In 1971, the Human Rights Commission adopted a preliminary draft of an international convention and the next year it produced the Draft Articles of the International Convention on the Protection of Journalists Engaged in Dangerous Professional Missions in Areas of Armed Conflict. Unfortunately, neither of the proposed legal texts has been officially adopted by the General Assembly to the present day. For the lack of a special treaty governing this issue, the protection of journalists is nowadays based on the rules of international law which are contained in human rights treaties and international humanitarian law. Although they do not contain specific legal provisions on the protection of journalists, human rights treaties contain some fundamental human rights which are valuable for the protection of journalists, such as: the right to life, the prohibition of torture and inhuman treatment or punishment, the freedom of expression and the freedom of movement. Some of these rights provide for their physical protection while others enable the exercise of their professional activities. Unlike human rights treaties, international humanitarian law does contain special provisions on the protection of journalists. International humanitarian law distinguishes between accredited war correspondents and 'independent' (free-lance) journalists. Both categories of journalists are regarded as civilians but war correspondents are given the status of prisoners of war in case they are captured by enemy. As all other civilians, journalists lose their protection if they take a direct participation in hostilities.
