This paper seeks to describe XML technologies and to show how they can be applied for developing web‐based courses and supporting authors who do not have much experience with the preparation of web‐based courses.

When developing online courses the academic staff has to address the following problem – how to keep pace with the ever‐changing technology. Using XML technologies helps to develop a learning environment which can be useful for academics when designing web‐based courses, preparing the materials and then reusing them.

The paper discusses the benefits of using XML for developing computer‐based courses. The task of introducing new versions of existing courses can be reduced to editing appropriate XML files without any need for program change and an author can perform this task easily from a computer connected to the internet. What is more – using XML makes it possible to reuse data in different teaching situations.

The environment has only been used for two years and further research is needed on how user‐friendly the system really is and how it can still be improved.

The paper describes the environment which can be used to develop and reuse online materials, courses, metadata etc.

The paper offers practical help to academics interested in web‐based teaching.

The aim of this paper is to examine how indoor aromatization affects the expressed and unexpressed satisfaction with the work environment in the production hall of an industrial company.

The aroma was flavored by an aromatization unit, the expressed satisfaction was measured on a scale and biometrics of facial recognition (FaceReader) was used to measure unexpressed satisfaction, enabling the recording of eight emotions and two basic emotions.

Research has shown the effect of aroma on two emotions – neutral and angry – which partially confirmed the sense of flavoring production facilities. Previous research has shown that positive feelings caused by a pleasant smell influence customers' purchasing decisions. As the use of aroma affects the mental state of the individual, it could be also applied for non-marketing purposes.

To date, there has been no research that systematically addresses the impact of aromatization on the perception of the work environment in a manufacturing company. The presented study is unique in its design and focus and provides basic information about the impact of aroma on individuals. The findings of this study can help to examine further aspects that indirectly affect performance.
