This paper considers those aspects of space technology which must be brought together into a system to carry educational programmes. The required levels of technology are achievable, but in such systems the space sector cost is much less than that of the ground sector, and an economic and effective system must optimize the spacecraft design in conjunction with the ground transmitters and particularly the large number of receiving stations. The implications of hybrid video systems are examined, incorporating fixed picture presentations, thus economizing on band-width demands, as alternatives to the use of normal television. A critical aspect of the educational system operation is likely to be the production of the software comprising the programmes. The implications of, and requirements for, these are discussed. Finally, the technical and logistic operational problems of a typical system are explored, emphasizing the critical relationship of design and serviceability of all elements of the system, and indicating the importance of planning adequate servicing and operational facilities.

The article examines the etymology and prehistory of the introduction of the institution of antimonopoly compliance in Russian business practice, the relationship of this institution with the institution of general compliance. The article considers the definition of the concept of antimonopoly compliance, enshrined in the new article 91 of the Federal Law "On Protection of Competition".The authors propose their own definition of the concept of antimonopoly compliance as an activity of an economic entity aimed at ensuring compliance with antimonopoly legislation by employees of an economic entity and an economic entity as a whole by preventing and suppressing violations of the requirements of such legislation and regulatory legal and law enforcement acts based on it.The authors also substantiate the advisability of developing a special national standard GOST R "System of internal compliance with the requirements of antimonopoly legislation (antimonopoly compliance system) of an economic entity".It is noted that the effectiveness of the antimonopoly compliance system will depend not only on the ability of an economic entity to form an antimonopoly compliance system on the basis of an appropriate national standard, but also on the state's ability to determine and guarantee effective incentives to comply with antimonopoly legislation.The authors substantiate the advisability of supplementing the Code of Administrative Offenses of the Russian Federation with provisions that provide for the obligation and limits to reduce the amount of punishment or replace the punishment with a softer one in the event of an anticompetitive administrative offense by a person who has implemented an effective system of antimonopoly compliance.

The article discusses the process of designing office work in the field of accounting for goods and equipment of objects of hotel and restaurant facilities. It is noted that it is one of the elements in the safety of tourism activities and a necessary component of the competitiveness of any enterprise operating in market conditions. It is noted that inadequate information on all possible directions of movement of purchased and manufactured goods leads to ineffective management decisions and deterioration of the enterprise. Therefore, there is a need for effective design of the accounting of goods and equipment in their information support. This will ensure the consistency and relationship of indicators of accounting registers; will provide information of the required level of detail and generalization, to meet the needs of management. The complexity of the construction of the accounting process for the objects of the hotel and restaurant economy is highlighted for the purpose of effective accounting and successful management of stocks of goods. To improve organizational support and design an effective system for documenting the accounting of goods and equipment of objects, an analysis of the directions of movement of goods and business transactions that arise in their process was carried out; the composition of accounting and control objects was clarified. In the hotel and restaurant industry, there are three main groups of business transactions related to the movement of goods: the receipt of placement and disposal of goods. In general, the organization of accounting for goods at the enterprise also includes three main stages: methodological, technical and organizational. At the same time, at all stages it is important to have timely primary accounting and a clear procedure for organizing the compilation and processing of primary documents, which is called the schedule of documents. There is a need to reflect the system of record keeping of goods in the Order on the accounting policy of the enterprise and its design given the rationality of accounting and the effectiveness of internal control to meet the information needs of owners at all stages of movement of goods.

System Functioning

The cargo system of FPSO units is of particular interest due to its rigorous operational requirements. In addition to structural and static stability requirements, the offloading operation of FPSO units should satisfy rigorous requirements related to the dynamic behavior of the vessel. In this sense, the cargo offloading process of FPSO units represents a critical aspect related to its design and operation. Unfortunately, due to the great computation effort usually required to analyze complex pipe networks, it is not a common practice to perform the analysis of the cargo system functioning at the design stage. This paper presents the analysis of the offloading operation of a typical FPSO unit. The analysis comprehends the simulation of the operation of the cargo system during the offloading process. The author adopted a new method to the analysis of pipe networks that seems to be more adequate for the analysis of fully branched systems. The results obtained indicate that the simulation of the cargo system operation is a useful tool for the analysis of the offloading process of FPSO units both at the design stage and during site operation.

Since 1999, the French Educational System has spread some units based upon the encounter between some teaching disciplines and the school documentation centre with an emphasis on the pupils’ interests, research and information re-writing methods and multi-disciplinary approaches. A set of “pedagogical barriers” seem to become open to change (a fragmented relationship of disciplines and knowledge, new constructions and assessments of the pupils’ work); however some new forms of barriers appear (such as technicist barriers, discrimination in access to information, new misunderstandings among pupils, etc.).

Significant Interference

Global Navigation Satellite Systems or GNSS is a space technology that has become an essential element nowadays for positioning, navigation & timing (PNT) with wide range of applications in many civilian sectors as well as across military. The reliability, accuracy and availability of GNSS are highly important especially for critical and precise positioning applications. However, the signals from space are weak and it can be easily blocked, disrupted or compromised by several other threats including intentional and unintentional interferences or jamming. GPS jammer is widely available off the shelf with an affordable price and capable of interfering the GPS signal, and many authorities worldwide have raised concerns and a lot of efforts and research have been put in place to reduce and mitigate the threats. In Malaysia, understanding and countering threats to GNSS/GPS based applications will be a new and unfamiliar discipline for public and organizations. This study intended to provide an overview of the GNSS interferences environment in a local study area, in terms of interference type and the number of activity pattern that were detected. A system called Detector V1 has been used in this study. The result showed that significant interference cases happened in the study area and some of the high power interferences may impact GNSS tracking and precision of the positioning output. The role objective of having this done is to create a public awareness regarding the threat of GNSS interferences to the local users. The content also includes the proposed initiative to overcome the issue.

Purpose – This paper aims to present a model that explains how knowledge contributions of international joint venture (“IJV”) partners can be balanced or imbalanced, which affects each partners’ trust needs, with implications for future partner relationships. Design/methodology/approach – Illustrative examples aid in explaining propositions associated with the knowledge/trust needs balance model. In addition, consideration is given to the trust-building complication of liability of foreignness and the implications balance or imbalance. Findings – In total, 12 illustrative cases are evaluated to determine whether the knowledge contributions of the IJV partners are balanced. Knowledge intensity associated with the venture is assessed to determine the value of the foreign firm partner’s knowledge contribution. Cultural distance between the relevant countries provides a measure of the host country partner’s knowledge contribution. Balance is assessed after factoring in mitigating partner experience. The cases provide examples of four different balance/imbalance situations. Practical implications – A critical aspect of a successful IJV is knowledge sharing and trust is required for the freest flow of information. It is important for firms entering into IJVs to more fully understand the relationship between the knowledge contributions of IJV partners and trust. When knowledge contributions are more evenly balanced, the relationship between the partners will be stronger. Originality/value – The paper distinguishes between balance and stability/instability, expands the literature on knowledge intensity and contributes the new concept of trust needs. Balance at the start of an IJV has implications for the future relationship of the partners.
