There are various macroscopic traces recognizable and readable on the surfaces of historical structures and materials. According to their origin they can be divided into several groups including traces of the transportation or other manipulation during construction; geometric schedules, height and direction lines, auxiliary design sketches; signs of wear and natural aging of materials; structural failures and impact of natural disasters; traces of subsequent additional modifications or conservation interventions; small epigraphical relics such as inscriptions, datings, the names of artisans or craftsmen, various graffiti etc.The traces of working tools are among the most important ones. They allow us to reconstruct forgotten arts and techniques performed by craftsmen or artisans in the past. For tool marks examination, the original surfaces intact with no later modifications or even conservation activities are very important. The sites with authentically preserved surfaces or details should therefore be registered, documented and then rigorously protected from adverse environmental factors and, if possible, in future spared any interventions including even attempts at conservation and restoration.

Tremendous progress has been made in industry including artificial intelligence, robotics and 4th generation of industry. People in most countries work smarter, hard work is supplied by machines and automatics do constantly repeated operations. Modern technology has made work smarter, quicker and more precise than human works. But there are still many problems to tackle. Tension on effective work is much than higher. Companies prioritize well educated people. The value of the company is measured not only by the level of financial capital, either intellectual capital is also rated. There are economic reasons for prioritizing effectivity in industrial development, and intellectual capital increasing level of effectivity. On the other hand, there are some arguments for prioritizing social and ethical responsibility. Economic growth could not be the only reason for development in business. In addition, involvement in corruption scandals and environmental accidents can severely damage the reputation of a company. Innovation in management is needed. Some results of investigations in that area suggested that ethical leadership could gain negative consequences of human behavior. Finally, it has been found that the development in ethical leadership could bring the benefits for employee and employers and can increase level of productivity and thus profits of companies. The main aim of the article is to describe an investigation of ethical leadership influence on companies.

The Candida hemagglutination test (Candida-HA-Test), the complement fixation, Candida immunofluorescent test (Candida-IF-Test) and the agglutination-test were performed in 34 patients suffering from genital candidosis and in 34 healthy controls. The results obtained were: Candida hemagglutination and complement fixation titers are raised to the same extent in patients suffering from Candida albicans-balanoposthitis when soluble polysaccharide antigens are used in both tests. The high titers indicate a great portion of mercaptoethanol susceptible antibodies in those subjects. When compared with controls, the hemagglutination titers are fourfold lower than those of the patients. There is a four-to-sixfold decrease of the hemagglutination titers performed after mercaptoethanol treatment of the sera in the patients. On the other hand, there is only a twofold decrease of hemagglutination titers in the controls. In chronically infected persons the hemagglutination titers are within the normal range or are raised insignificantly. There is only a twofold decrease in HA-titers after treatment of the sera with mercaptoethanol. On the other hand, the agglutination- and the Candida-IF-titers seem to be elevated as a rule in chronically infected. In those patients the gamma G- and the gamma A-titers are significantly raised, too. The results mentioned above are discussed with regard to their clinical significance.

The aim of this paper is to present the Report of innovative restoration techniques, technologies and materials used in conservation in the context of natural sciences and heritage science of the RUINS Project. First, the specifics of preservation and maintenance of ruins are briefly described. Subsequently, the context of natural sciences and the new scientific discipline of heritage science, including the link to innovation, are indicated. The paper then presents the structure of the report and an example of one record representing one specific technique. Record structure is ready to be transferred to versatile data set so it could be converted into an updatable online database in the future.
