Metadata enhanced content management in media companies
Media companies are facing new opportunities and challenges. Communications, computing, and content industries are converging into a single, horizontally connected content value chain, where changes are frequent and activities are highly interdependent. However, before convergence and digital content are taken seriously, media companies must understand what is expected from them, how their operations will be affected, and why they should be involved.
The production, distribution, and use of content rely heavily on computers and automation. This requires the content essence to be enhanced with explicit descriptions of semantics, or more specifically, semantic metadata. However, semantic metadata is useful only if its nature is understood clearly, and when its structure and usage are well defined. For this purpose, ontologies are needed to capture the essential characteristics of the content domain into a limited set of meaningful concepts.
The creation and management of ontologies and semantic metadata require skills and activities that do not necessarily exist in traditional print-based publishing or broadcasting. Companies developing ontologies must understand the essential characteristics of available content, user needs, and planned or existing use of content. Furthermore, they must be able to express this information explicitly in an ontology and then reflect changes in the environment back to that ontology.
Content production and distribution should be flexible and able to support the reuse of content. This thesis introduces two abstract models, a component model and a process model. Both models assist in the understanding and analysis of electronic publishing of content for multiple media products and on multiple media platforms.
When semantic metadata, ontologies, and improved publishing processes are available, new advanced content-based products, such as personalized information feeds, are possible. The SmartPush project, for which the author was the project manager and worked as a researcher, has shown that semantic metadata is useful in creating advanced content-based products, and that media companies are willing to alter their existing publishing processes. Media companies participating in the SmartPush project have acknowledged the impact of our work on their plans and operations. Their acknowledgement emphasizes the practical importance of semantic metadata, ontologies, improved electronic publishing process, and personalization research.reviewe
Depth sensors in augmented reality solutions. Literature review
The emergence of depth sensors has made it possible to track â not only monocular
cues â but also the actual depth values of the environment. This is especially
useful in augmented reality solutions, where the position and orientation (pose) of
the observer need to be accurately determined. This allows virtual objects to be
installed to the view of the user through, for example, a screen of a tablet or augmented
reality glasses (e.g. Google glass, etc.). Although the early 3D sensors have
been physically quite large, the size of these sensors is decreasing, and possibly â
eventually â a 3D sensor could be embedded â for example â to augmented reality
glasses. The wider subject area considered in this review is 3D SLAM methods,
which take advantage of the 3D information available by modern RGB-D sensors,
such as Microsoft Kinect. Thus the review for SLAM (Simultaneous Localization
and Mapping) and 3D tracking in augmented reality is a timely subject. We also try
to find out the limitations and possibilities of different tracking methods, and how
they should be improved, in order to allow efficient integration of the methods to
the augmented reality solutions of the future.Siirretty Doriast

Poor respiratory health outcomes associated with high illness worry and alexithymia : Eleven-year prospective cohort study among the working-age population
Objective: Poor respiratory health outcomes have been associated with poorer physical health and higher psychological distress. The aim of this study was to investigate whether illness worry, alexithymia or low sense of coherence predict i) the onset of new respiratory disease, ii) respiratory symptoms or iii) lung function among the working-age population, independently of comorbidity mood-, anxiety, or alcohol abuse disorders.& nbsp;Methods: The study was conducted among a nationally representative sample of the Finnish population (BRIF8901) aged 30-54 years (N = 2310) in 2000-2001 and was followed up in 2011. Individuals with a diagnosed respiratory disease or a severe psychiatric disorder at baseline were excluded. Lung function was measured by a spirometry test and psychiatric disorders were diagnosed using a structured clinical interview. Structured questionnaires were used to measure self-reported respiratory symptoms and diseases, illness worry, alexithymia, and sense of coherence.& nbsp;Results: High illness worry predicted an 11-year incidence of asthma (OR 1.47, 95% CI 1.09-1.99, p = 0.01). Alexithymia predicted shortness of breath (OR 1.32, 95% CI 1.13-1.53, p < 0.01) and 11-year incidence of COPD (OR 2.84, 95% CI 1.37-5.88, p < 0.01), even after several adjustments for physical and mental health. Psychological dispositions did not associate with lung function in 2011.& nbsp;Conclusions: In the general population, psychological factors that modify health behaviour predicted adverse respiratory health outcomes independently of lung function after 11 years of follow-up. This indicates that considering them part of personalized treatment planning is important for promoting health-related behaviour among the working-age population.Peer reviewe
Depth sensors in augmented reality solutions. â Literature review
The emergence of depth sensors has made it possible to track – not only monocular cues – but also the actual depth values of the environment. This is especially useful in augmented reality solutions, where the position and orientation (pose) of the observer need to be accurately determined. This allows virtual objects to be installed to the view of the user through, for example, a screen of a tablet or augmented reality glasses (e.g. Google glass, etc.). Although the early 3D sensors have been physically quite large, the size of these sensors is decreasing, and possibly – eventually – a 3D sensor could be embedded – for example – to augmented reality glasses. The wider subject area considered in this review is 3D SLAM methods, which take advantage of the 3D information available by modern RGB-D sensors, such as Microsoft Kinect. Thus the review for SLAM (Simultaneous Localization and Mapping) and 3D tracking in augmented reality is a timely subject. We also try to ïŹnd out the limitations and possibilities of diïŹerent tracking methods, and how they should be improved, in order to allow eïŹcient integration of the methods to the augmented reality solutions of the future.

The association of psychological factors and healthcare use with the discrepancy between subjective and objective respiratory-health complaints in the general population
Background. We examined the prevalence of self-perceived respiratory symptoms (SRS) in the absence of any objective findings of respiratory pathology, and the association of such prevalence with psychological factors and healthcare use in the general population. Methods. The study was conducted among a nationally representative sample of Finnish adults (BRIF8901). Respiratory functioning was measured by a spirometry test. Structured questionnaires were used to measure SRS, physician visits and psychological factors of alexithymia, sense of coherence, illness worry and common mental disorders. Individuals with a diagnosed respiratory disease or a severe psychiatric disorder, determined in a diagnostic interview, were excluded, giving a sample comprising 4544 participants. Results. Twenty-six per cent of the general population and 36% of those with no diagnosed severe psychiatric disorder or respiratory disease experienced SRS despite a normal spirometry result. Psychological factors were associated with SRS (0.0001 <p <0.032), and on the number of physician visit explaining 42.7% of the difference in visits between individuals with and without SRS, respectively. Illness worry was associated most strongly with SRS [odds ratio (OR) 1.29, 95% confidence interval (CI) 1.19-1.41, p <0.0001] and higher numbers of physician visits (OR 1.35, CI 1.32-1.38, p <0.00001), even after several adjustments. Conclusions. Respiratory symptoms without objective findings are common in the general population. The study results underline the role of psychological factors in the reporting of respiratory symptoms and the associated medical burden, thereby indicating the functional nature of the symptomatology.Peer reviewe

Redan i kring tjugo Ă„rs tid har det organiserats publika utgrĂ€vningar i Finland, men angĂ„ende deras roll i den finska arkeologin har det inte diskuterats i nĂ„gon större utstrĂ€ckning. Gemensamma riktlinjer för de publika utgrĂ€vningsprojektens praktiska aspekter har hittills saknats, inte heller har det funderats vidare kring de etiska frĂ„gorna som berör sĂ€rskilt publika utgrĂ€vningar. Dessa Ă€renden behandlades i seminarier som arrangerades i Tammerfors och Ă
bo Ären 2018 och 2019, dÀrtill utfördes en enkÀtförfrÄgan till organisatörer av publika utgrÀvningar. UtgÄende frÄn seminariediskussionerna och enkÀtsvaren sammanstÀlls i denna artikel hurudan praxis som visat sig fungerande vid planering och genomförande av publika utgrÀvningsprojekt.</p
