The basic condition of forest management development is the accessibility of the forest. A design of the forest road network in relation to all-society functions of forests has been made in the catchment of the Vilčok stream. The catchment is situated in Protected Landscape Area Beskydy. The method Quantification and quantitative evaluation of functions of forests as a basis for their evaluation (Vyskot et al. 2003) was used for the design. This method can be applied to road planning. It can serve as another component in the decision-making process of the planning of forest road construction.

In most cases, the planning of funding for the construction of a forest truck road causes difficulty to planners. Although a forest management plan (FMP) indicates the number of roads to be built annually for the next development period with the average cost of construction, this information is quite general and based on experiential estimates. The aim of this paper is to determine the average cost of forest truck road construction in the Republic of Srpska, as well as to calculate the average costs of individual phases of operation. The obtained average cost of forest road construction, resulting from the analysis of 71 major projects in 11 forest areas encompassing 178 km of forest roads, is 32,490.87 ?/km. The obtained results point to the interesting fact that forest road construction is the most expensive in hilly areas with an altitude ranging between 200 and 500 m (34,298.28 ?/km), while it is the cheapest (30,922.88 ?/km) in medium mountainous areas, with altitudes between 1000 and 2000 m.

A traditional approach to problems of the opening-up of forests has been based primarily on technical and economic aspects. It results particularly from the ground configuration and calculations of minimum costs for logging and transport operations. Optimum density of main forest roads is determined by a minimum value of the summary curve of costs of forest road construction and timber skidding. A new conception from the aspect of integrated forest management taking into account forest functions is based on a standard approach when technical and economic aspects are complemented by the particular functions of the forest. Thus, the technical and economic approach is changed to a technical-economic-environmental conception that will contribute to a reduction in negative effects of the construction of forest road network on the environment.

Forest road planning is a time-consuming and complicated process both because it requires environmentfriendly road building, and due to the requirement to observe economic costs. This costs will be increase depending on maneuverability requirements of vehicle dimension. The main aim of this study is to analyze maneuverability of recreational vehicles on forest roads that primarily serve utilization of vehicles intended for production as well as geometrical characteristics of roads on computer environment. Both dynamic horizontal driving analysis and dynamic vertical driving analysis can be made with Autopath driving analysis module of Plateia 2013 software. Computer-aided horizontal driving analysis, which is used in examination of opportunities for utilization of available roads by different vehicle types, appears as an effective method for the decision maker in consideration of geometrical standards of vehicles during decision-making process. Graphical report is another output of driving analysis which visually presents vehicle maneuverability. In this context, Maneuverability of automobile, midibus and bus were analyzed on forest road with 4 m platform width. As a results of this study, it was concluded that computer-aided driving analysis is a beneficial tool in decision making process for re-planning of forest roads. As a consequence, it is considered that driver safety, as well as project costs, would increase by utilization of driving analysis during forest road planning and design.

In Canada, Lemmon's Holly Fern, Polystichum lemmonii, is restricted to the Baldy Mountain area on the eastern side of the Okanagan River valley in south-central British Columbia. This population represents the northern limits of the species which ranges south through northern Idaho, Washington and Oregon to northern California. In British Columbia, P. lemmonii is associated with ultramafic rocky ridges within a montane forest at an elevation of 1900 m. The population in the Baldy Mountain area is relatively small, unprotected and potentially imperilled by mining exploration, forest road construction or wildfires.

The paper investigates how different hierarchy structuring in analytic hierarchy process (AHP) may affect the final results in the decision-making process. This problem is analyzed in a case study of the Rila monastery forest stands in Bulgaria. There were three similar and mutually overlapped hierarchies defined. A decision maker evaluated all of them and after analyzing final results and consistency performance, he selected and revised the most appropriate hierarchy structure. Consistency check assisted in detecting the judgments which have strongly violated evaluation procedure. These mistakes are interpreted as a consequence of a large number of required pair-wise comparisons. The paper emphases the importance of properly defining hierarchy structure and recommends using consistency analysis as a guide and not as a directive for the revision of judgments.

The past few years, many organizations have been using the Internet in quite arbitrary and experimental ways. This phase, which can be considered as a period of learning and experimentation, has created a need for a more systematic approach to the identification, the ordering and the assessment of e-business options. It is the objective of this paper to address this need by presenting a methodology that aims at supporting management in using alternative e-business applications in the first stage of the decision-making process. Figure 1 shows how a systematic decision-making process can be organized by using e-business options. The steps are based on Simon’s intelligence, design, and choice trichotomy (Simon, 1960). First, alternative e-business options have to be identified and ordered. Then the possible options have to be assessed and selected. After this stage the selected opportunities have to be specified and designed. Next, implementation, operation, maintenance, and evaluation may follow. In Figure 1 this is called the “formal life cycle”. We will apply the word “e-business option” referring to the possibility to use an electronic network for a business purpose. An e-business opportunity is defined here as an assessed and selected e-business option. In practice, different intermediate feedback activities, interrupts, delays and adjustments are often necessary to reconsider earlier steps (Mintzberg, Raisinghani, & Théorêt, 1976). This is—among other reasons—because decision-making processes of this kind take place in dynamic environments and decisions are made in political contexts (Pettigrew, 2002). Moreover, participants in decision-making processes are often lacking the necessary information to make well-considered decisions right from the start (Miller, Hickson, & Wilson, 1996). In Figure 1 these activities are called “intermediate feedback”.

Abstract A computer program has been developed to aid forest engineers in the cost estimation of forest road construction activities. This new tool, called ACCEL, uses Visual Basic for Applications within Microsoft Excel to compute the costs of construction components using interactive sheets, automated tasks, and advanced computer routines. The user is guided through road construction components and prompted for cost data, earthwork quantities, survey information, and the conditions of the construction environment to estimate total construction cost. Road design elements and site characteristics are variables used to optimize earthwork allocation, improving on using the mass diagram method. The program also estimates clearing and grubbing areas, rock surfacing volumes, and culvert lengths. ACCEL was validated by comparing the results to those of RoadEng (by Softree), ensuring that formulas were input correctly and showing close agreement in results. This program was created in a recognizable format, i.e., Microsoft Excel, and builds on basic quantity and cost estimation techniques. ACCEL is intended to improve the decisionmaking process for experienced forestry practitioners in forest road construction regardless of region, company, or agency affiliation by accepting their inputs and performing the calculations for different route alternative or varying design specifications.

Threats have accompanied humanity since the dawn of time. Most of them can develop into crisis situations that can be interpreted in many different ways. The crisis situation is closely linked with the concept of crisis management, which is implemented in four phases. At every stage of work, various elements are significant in terms of crisis management. There are also elements that are very important at every stage. These include: threat analysis, estimation of the probability of their occurrence in a given area, and assessment of their sensitivity. An appropriate information flow system supports the implementation of the above elements. This system should be effective in such relations as between services and between services and society. The effectiveness of information flow depends on the reliability of this information and its flow channel. Information is of particular importance in the decision-making process. It should have appropriate features and properties. Based on the information, both good and bad decisions can be made. In crisis management, this can be relevant to human health and even human life. This article discusses issues related to the nature of information in crisis management.

Governance today is of paramount apprehension for any state. Concern for governance therefore reveals new areas of articulation for a state and the people living within its jurisdiction. For many, governance refers to certain conditions necessary for a state through which it can exercise power in managing the nation's social and economic assets and also becomes the precondition for realizing democratic ideals. Though the notion of governance is different for different people, one common understanding of it is the decision making process as well as the process of implementation of those decisions. This process also identifies involvement of different structures from different walks of life, signifying both the formal as well as informal actors. In this background, the traditional institutions of a society also have their appeal for involvement of local structures in the issues of governance. The traditional institutions of Karbi Anglong also entails such appeals, because of its involvement in civil, socio-economic and religious jurisdiction of the local interests. Therefore the participation of people through such institutions has been recognized as a process of grass rooting the democratic principle of governance in its most popular form as mentioned above. In this paper an attempt is made in recognizing the effect of the traditional institutions in Karbi Anglong more specifically among the Karbi Tribes.
