The present methodological proposal allows the generation of three-dimensional maps of vulnerability for breakwaters, through the employment of videoimagery techniques and statistical analysis. On one hand, the knowledge of videoimagery techniques (Molina et al., 2005) as an extended and applicable tool for maritime engineering (ZEUS Project “Zenital Unattended System”) and on the other hand the usefulness of applying statistical techniques to the study of damage evolution in maritime structures motivated the fusion of both to obtain wide information from the images which is not evident to the naked eye. The 3D maps show graphically the behaviour of breakwaters facing the actions of the environment, and this makes the tasks of conservation, maintenance or design easy and improve damage prediction for a better management during the building process.

Abstract The art of bodypainting that is fairly unknown to a wider public turns the body into a canvas - it is a frequently used phrase in the field of bodypainting that illustrates the challenge it faces: it uses a three-dimensional surface and has to cope with its irregularities, but also with the model’s abilities and characteristics. This paper looks at individuals who are turned into art by bodypainting. Although body painting can be very challenging for them - they have to expose their bodies and to stand still for a long time while getting transformed - models report that they enjoy both the process and the result, even if they are not confident about their own bodies. Among the reasons there are physical aspects like the sensual enjoyment, but also the feeling of being part of something artistic. This is enhanced and preserved through double staging - becoming a threedimentional work of art and then being staged for photography or film clips. This process gives the model the chance to experience their own body in a detached way. On the one hand, bodypainting closely relates to the body and on the other hand, it can help to over-come the body.

First Session

The purpose of this study was to compare the effectiveness of plaque control performed with electric and manual toothbrushes. Fifteen children with primary dentition and 14 children with mixed dentition were divided in two groups and randomly assigned to utilize a manual or an electric toothbrush. In the first session, professional plaque removal was performed, and the children spent 24 hours without brushing their teeth. In the second session, plaque was disclosed and assessed on all facial and lingual surfaces. After that, all children brushed their teeth with the predetermined toothbrush. The next procedure was the disclosure and measurement of residual plaque. After a period of 7 days, the children switched the kind of toothbrush, and the same procedures were repeated. According to the statistical analysis of the results, there were no significant differences concerning plaque removal when the toothbrushes were utilized by children with mixed dentition. On the other hand, the electric toothbrush promoted significantly greater plaque removal on the lingual surfaces of teeth from children with primary dentition.

In a study on the prevention of injury in patients with H63D syndrome and cataplexy, statistical analysis revealed an unexpected but clinically highly significant finding. Apparently, in this patient population, an inverse correlation exists between the severity of tic symptomatology on the one hand and narcolepsy with cataplexy on the other hand, as well as a parallel increase in the typical signs of degeneration observed in transcranial sonography of the substantia nigra. This finding has clinically far-reaching implications.

Scherk's graph is a subgraph of the three-dimensional lattice. It was shown by Markvorsen, McGuinness and Thomassen (1992) that Scherk's graph is transient. Consider the Bernoulli bond percolation in Scherk's graph. We prove that the infinite cluster is transient for p > ½ and is recurrent for p < ½. This implies the well-known result of Grimmett, Kesten and Zhang (1993) on the transience of the infinite cluster of the Bernoulli bond percolation in the three-dimensional lattice for p > ½. On the other hand, Scherk's graph exhibits a new dichotomy in the supercritical region.

There is no doubt to the fact that globalization has become a buzz word of our time and has significantly impacted the whole world and Africa without exception. Despite it being a buzz word, it has also become very confusing. Some people when asked to specify how they understand it, reply with considerable hesitation, vagueness and inconsistency. However, whether one understands it or not, the fact remains that globalization is real and it is impossible to avoid it, but we have to act. In recent decades globalization has become a factor that obstructs nation-building process in the developing world and Africa in particular. Increasing inequalities between social classes, ethnic groups, regions and nations are on the rise while nations are becoming more powerless to solve these problems. On the other hand, globalization will represent a golden opportunity for nation-building process, if Africa manages to grab the opportunities presented.

The Ideal

The water-powder relationship is essential to achieve a proper performance of gypsum for prosthetic purposes. The ideal measure can be obtained with a balance, but this is clinically unavailable, once it is timeconsuming. A powder-compacting technique using a volume measurement is suggested in order to substitute the balance. The technique consists of using a gypsum meter within the gypsum bag. While the operator holds the gypsum meter with one hand, the palm of the other hand is pressed over the surface of the meter, supported by the ventral aspect of the fingers of the hand that is pressing. This procedure is based upon three compactation movements for each operator, then counting the average of compacting sample. Each of the ten operators repeated six times the procedure, and the final average was defined. The resulting samples for each procedure, of each operator, were weighted, and the statistical analysis showed significant differences (p = 0,006) among the operators.

Due to the hazardous current cyber environment, cyber resilience is more necessary than ever. Companies are exposed to an often-ignored risk of suffering a cyber incident. This places cyber incidents as one of the main risks for companies in the past few years. On the other hand, the literature meant to aid on the operationalization of cyber resilience is mostly focused on listing the policies required to operationalize it, but is often lacking on how to prioritize these actions and how to strategize their implementation. Therefore, the usage of the current literature in this state is not optimal for companies. Thus, this study proposes a progression model to help companies strategize and prioritize cyber resilience policies by proposing the natural evolution of the policies over time. To develop the model, this study used semi-structured interviews and an analysis of the data obtained from the interviews. Through this methodology, this study found the starting points for each cyber resilience policy and their natural progression over time. These results can help companies in their cyber resilience building process by giving them insights on how to strategize the implementation of the cyber resilience policies.

The Empirical Analysis

Although we appreciate the attention the critic has given to our paper, we are somewhat disappointed about the kind of criticism. It is said that the ‘empirical analysis is fundamentally flawed’. But if the analysis is flawed it must be very easy to show it by a reanalysis of the data. However, if one takes the time to look at the data used in this study one can see immediately that when the USSR's level of armaments is very low the USA is producing large amounts of missiles. On the other hand, when the USSR has a large number of missiles the USA's production is nil or very little. Consequently one must conclude that the USA cannot possibly be reacting to the activities of the USSR in the simple ways suggested by Richardson or Hamblin et al. This result was confirmed by our statistical analysis of the data. One can of course try other statistical procedures, as we did, but they all produce the same result: there is no reaction effect in the USA's behaviour.

The technological growth in the last years have conducted to the development of virtual reality (VR) systems able to immerse the user into a three-dimensional (3D) virtual environment where the user can interact in real time with virtual objects. This interaction is mainly based on visualizing the virtual environment and objects. However, with the recent beginning of haptic systems, the interaction with the virtual world has been extended to also feel, touch and manipulate virtual objects. Virtual reality has been successfully used in the development of applications in different scientific areas ranging from basic sciences, social science, education and entertainment. On the other hand, the use of haptics has increased in the last decade in domains from sciences and engineering to art and entertainment. Despite many developments, there is still relatively little knowledge about the confluence of software, enabling hardware, visual and haptic representations, to enable the conditions that best provide for an immersive sensory environment to convey information about a particular subject domain. In this paper, the state of the art of the research work regarding virtual reality and haptic technologies carried out by the authors in the last years is presented. The aim is to evidence the potential use of these technologies to develop usable systems for analysis and simulation in different areas of knowledge. The development of three different systems in the areas of engineering, medicine and art is presented. In the area of engineering, a system for the planning, evaluation and training of assembly and manufacturing tasks has been developed. The system, named as HAMS (Haptic Assembly and Manufacturing System), is able to simulate assembly tasks of complex components with force feedback provided by the haptic device. On the other hand, in the area of medicine, a surgical simulator for planning and training orthognathic surgeries has been developed. The system, named as VOSS (Virtual Osteotomy Simulator System), allows the realization of virtual osteotomies with force feedback. Finally, in the area of art, an interactive cinema system for blind people has been developed. The system is able to play a 3D virtual movie for the blind user to listen to and touch by means of the haptic device. The development of these applications and the results obtained from these developments are presented and discussed in this paper.
