Developing the "Choosing Health" Digital Weight Loss and Maintenance Intervention: Intervention Mapping Study
2022
Background Digital health promotion programs tailored to the individual are a potential cost-effective and scalable solution to enable self-management and provide support to people with excess body weight. However, solutions that are widely accessible, personalized, and theory- and evidence-based are still limited. Objective This study aimed to develop a digital behavior change program, Choosing Health, that could identify modifiable predictors of weight loss and maintenance for each individual and use these to provide tailored support. Methods We applied an Intervention Mapping protocol to design the program. This systematic approach to develop theory- and evidence-based health promotion …
Inflammation status of healthy young men : initial and specific responses to resistance training
2018
Our primary aim was to study the effects of a 4-week preparatory resistance-training (RT) period followed by 12 weeks of 2 specific RT protocols (either hypertrophic-strength (HS) or strength-hypertrophy-power training) on inflammation markers and the possible relationship of the changes in abdominal fat and lean mass to the changes in inflammation status. A total of 82 healthy men were included in the study. Maximal concentric leg press strength (1-repetition maximum), total body lean mass, total body and abdominal fat mass, circulating high-sensitivity C-reactive protein, interleukin-6, interleukin-1 receptor antagonist (IL-1ra), monocyte chemoattractant protein 1 (MCP-1), and selected ad…
A reckoning with the maintenance of the built environment, a Sisyphean task
2023
Maintenance concerns most of the artifacts, referring simultaneously to the socio-cultural, technical and managerial spheres. Contemporary scenarios impose an overall rethinking, where key-topics such as tradition, consumerism, sustainability and digitization become pivotal in the search for suitable production models, between post-industrial and neo-craftsmanship, in order to have fresher references for the maintenance activities.
 In the construction field, maintenance is not limited to the objective of prolonging the duration of quality levels that only affect direct users, but also has important implications of a social and collective nature, in the case of both public and private …
Artificial Intelligence in Monitoring and Diagnostics of Electrical Energy Conversion Systems
2020
Diagnostics and prognostics of electrical energy conversion systems are moving forward with the rapid development of IT and artificial intelligence possibilities. This also broadens the horizons for classical and advanced condition and operation monitoring techniques, resulting in more accurate fault detection, degradation prognosis and calculation of remaining life of energy conversion systems, utilized in every aspect and field of industry today. This paper gives an overview of the necessity for condition monitoring and diagnostics of the mentioned systems, explaining the classical and advanced techniques for diagnostics. Methodology to diagnose and prognose the energy conversion units, w…
Smart Technologies for Improved Software Maintenance
2015
Steadily increasing complexity of software systems makes them difficult to configure and use without special IT knowledge. One of the solutions is to improve software systems making them “smarter”, i.e. to supplement software systems with features of self-management, at least partially. This paper describes several software components known as smart technologies, which facilitate software use and maintenance. As to date smart technologies incorporate version updating, execution environment testing, self-testing, runtime verification and business process execution. The proposed approach has been successfully applied in several software projects.
The United Nations and the European Union
2019
The European Union (EU) and the United Nations (UN) are expressions of a rules-based global order. The EU has enshrined support to the UN in its security strategies, and its priorities indicate an engagement in a wide range of UN programs and activities to maintain the rules-based order and adapt it to face internal and external challenges. The EU and its member states are the largest contributors to the UN budget. Following the adoption of the Lisbon treaty, the EU has increased its representation at the UN, gaining enhanced observer status in the General Assembly. However, because of the intergovernmental nature of the forum, only its member states have the right to vote. This has led sch…
IS evolution benefit assessment: Challenges with economic investment criteria
2007
Maintenance and system evolution activities have a significant role in the information system (IS) life cycle. It has been estimated that approximately 80% of the total IT expenses are allocated for maintenance activities [20]. According to Lehman’s first law, maintenance is necessary, because software needs to be continuously improved or it will get out of date and cannot respond to the requirements of its environment [19]. Despite the importance of IS evolution investments, there is a gap between the IT related costs and company profitability [27]. Brynjolfssen [10] described this as a productivity paradox: information technology utilization has increased since the 70’s but simultaneously…
Cerība un tās nozīme smagi slimu pacientu aprūpē
2021
Jau izsenis cerības jēdziens ir ticis aktīvi locīts daudzu tautu kultūrās. Tā izpratne un lietojums dažādos laikos un dažādās kultūrās gan bijis visai atšķirīgs. Sākotnēji apspriesta teologu vidū, cerība saistījusi arī filozofu prātus, bet līdz ar zinātņu (it īpaši veselības zinātņu) attīstību aizvien lielāka nozīme tai piešķirta arī zinātnieku, sevišķi darbojošos medicīnas jomā, aprindās. Apjomīgais, ar cerību saistītais, pētījumu klāsts liecina, ka arī šodien šī interese nav mazinājusies. Gluži otrādi, attīstoties medicīnas un humanitāro zinātņu nozarēm, cerības kā būtiska resursu avota aktualitāte ir tikai augusi, kļūstot par visnotaļ aizraujošu sava veida “izpētes objektu” arī plašajā p…
An effective approach for the maintenance scheduling in large systems with required reliability level: A case study
2015
This paper deals with the problem of the maintenance scheduling in a multi-component system for which a required reliability level has to be warranted until the next planned stop for maintenance. Particularly, the tackled problem concerns both the determination of the elements set on which to perform preventive maintenance and the optimal number of maintenance crews in order to warranty the required reliability level at the minimum maintenance cost. The problem is formulated as a mathematical programming model that becomes very hard to solve for large practical systems. For such reason, a new effective approach based on a constrained genetic algorithm is herein proposed and tested with refe…
