Lighting at the end of the tunnel:the design of adaptive and intelligent lighting for an underground workspace
Abstract. Callio has been established to manage the rehabilitation of Pyhäsalmi Mine into a world-class business and research underground facility. The reuse of Pyhäsalmi Mine serves as a backdrop for studying the effects of artificial light in an underground workspace. This provides a rationale for a hypothesis respecting the lighting environment as affecting the physiological and psychological state of people working in environments with restricted exposure to natural light. Although the current lighting infrastructure may be sufficient for mining operations, it is questionable that the visual and non-visual lighting requirements of the future users of the deep underground facility can be fulfilled under the existent lighting conditions. The main research question that this thesis intends to study is the ways in which future users of the deep underground workspace may benefit from adaptive and intelligent lighting in their day-to-day work activities. Whether the influence of a workspace equipped with adaptive and intelligent lighting and designed through a set of architectural lighting principles may promote well-being of employees and guests.
The first part of this thesis presents the theoretical background of the visual and non-visual effects of light and workspace architecture. The second part introduces the implementation of adaptive and intelligent technologies to architectural lighting design in the context of creating a new working environment in two underground spaces in Callio. Located on the main level, Retka restaurant will also operate as the new information centre. A few metres deeper, the Lab 2 will offer a new floor for research and business activities.
Through a series of scenarios, the design implementation of adaptive and intelligent lighting aims to respond to the visual and non-visual requirements of light of the future users of the deep underground workspace. The production of detailed descriptions for each scenario provides a robust conceptual framework for the lighting design. It aims to unfold the most adequate lighting behaviour that suits the underground working environment. The implementation plan for the lighting designs form a basis for future lighting pilots whereby the effects of lighting in underground environments will be studied
Omni-Channel Intensity and Shopping Value as Key Drivers of Customer Satisfaction and Loyalty
Omni-channel retailing consists of the complete alignment of the different channels and touchpoints that generate a seamless experience for consumers, allowing them to move freely through all channels. The consumer's perception of a seamless and consistent omni-channel experience is called intensity. This study reveals that this intensity in the shopping experience can offer value to consumers, and that intensity and shopping value also influence satisfaction and loyalty. We propose a relationship model that had been tested in a quantitative study with PLS, with a representative sample of buyers who had used the Click and Collect system. The main contribution of this study is to the literature on the analysis of omni-channels from the consumer experience perspective, through an in-depth analysis of the concepts of intensity and shopping value, as well as their relationship with satisfaction and loyalty. The results revealed the existence of a positive relationship between intensity and shopping value, and between these two variables and satisfaction and loyalty. Keywords: omni-channel; intensity; shopping value; satisfaction; loyalt

Using RAW as control plane for wireless deterministic networks: challenges ahead
MobiHoc '23: Proceedings of the Twenty-fourth International Symposium on Theory, Algorithmic Foundations, and Protocol Design for Mobile Networks and Mobile Computing, 23-26 October 2023, Washington DC, USA.This paper provides an extensive analysis of Reliable and Available Wireless (RAW) enhancements and solutions needed to manage industrial environments more effectively. Starting from the description of a representative industrial use case, an analysis of gaps and promising new extensions is performed. Namely, the need to (i) support multi-domain operation, at both technology and administrative levels; (ii) integrate RAW with edge architectures; and, (iii) increase the mobility support in RAW networks. The identified gaps are indeed not yet tackled by the relevant standardization development organizations, mainly the Internet Engineering Task Force (IETF), and are thus object of our future work.This work has been partially funded by the European Commission Horizon Europe SNS JU PREDICT-6G (GA 101095890) Project and the Spanish Ministry of Economic Affairs and Digital Transformation and the European Union-NextGenerationEU through the UNICO 5G I+D 6G-EDGEDT and 6G-DATADRIVEN
Impact of non-adherence to radiotherapy on 1-year survival in cancer patients in Catalonia, Spain
This study aims to assess the effects of non-adherence to external beam radiation therapy in cancer patients receiving treatment with a curative. This retrospective cohort study collected health records data for all cancer patients treated with external beam radiotherapy with curative intent in 2016 in Catalonia, Spain. Adherence was defined as having received at least 90% of the total dose prescribed. A logistic regression model was used to assess factors related to non-adherence, and its association with one-year survival was evaluated using Cox regression. The final sample included 8721 patients (mean age 63.6 years): breast cancer was the most common tumour site (38.1%), followed by prostate and colon/rectum. Treatment interruptions prolonged the total duration of therapy in 70.7% of the patients, and 1.0% were non-adherent. Non-adherence was associated with advanced age, female gender, and some localization of primary tumour (head and neck, urinary bladder, and haematological cancers). The risk of death in non-adherent patients was higher than in adherent patients (hazard ratio [HR] 1.63, 95% confidence interval 0.97-2.74), after adjusting for the potential confounding effect of age, gender, tumour site and comorbidity. Non-adherence to radiotherapy, as measured by the received dose, is very low in our setting, and it may have an impact on one-year survival
Autolesiones no suicidas en adolescentes: revisión de los tratamientos psicológicos
Self-harm in teenagers has become more important in recent years, given its increased prevalence and the greater risk involved of making a suicidal attempt and developing a borderline personality disorder or a major depressive disorder. We aim to review the literature as to psychological treatments for non-suicidal self-injury (NSSI). Studies assessing a psychotherapeutic intervention for self-harm have been included. The results indicate that no treatment for self-harm has demonstrated enough evidence in adolescents. Mentalization based therapy (MBT-A) has shown efficacy in one study and the dialectical behavior therapy (DBT-A) has shown efficacy. However, the variety and heterogeneity of results make it difficult to draw more specific conclusions, such as regards the effective active components. Criteria and instruments in the field of the treatment of NSSI need to be standardized in order to improve the validity and clinical utility of results.Las autolesiones en adolescentes han adquirido mayor relevancia en los últimos años, por el aumento de prevalencia, el mayor riesgo de realizar una tentativa autolítica y de desarrollar un trastorno límite de la personalidad o un trastorno depresivo mayor. Nuestro objetivo es revisar la bibliografía referente a tratamientos psicológicos para las autolesiones no suicidas (non-suicidal self-injury; NSSI). Se incluyen estudios que evalúan una intervención psicoterapéutica para el tratamiento de las autolesiones. Los resultados indican que ningún tratamiento para las autolesiones ha demostrado suficiente evidencia en adolescentes. La terapia basada en mentalización (MBT-A) ha demostrado eficacia en un estudio y la terapia dialéctica-conductual (DBT-A) ha demostrado efectividad. La variedad y heterogeneidad de resultados dificulta extraer conclusiones más específicas, como cuáles son los componentes activos eficaces. Valoramos la necesidad de estandarizar criterios e instrumentos en el campo del tratamiento de las autolesiones para mejorar la validez y utilidad de los resultados

HII Region Metallicity Distribution in the Milky Way Disk
The distribution of metals in the Galaxy provides important information about
galaxy formation and evolution. HII regions are the most luminous objects in
the Milky Way at mid-infrared to radio wavelengths and can be seen across the
entire Galactic disk. We used the NRAO Green Bank Telescope (GBT) to measure
radio recombination line and continuum emission in 81 Galactic HII regions. We
calculated LTE electron temperatures using these data. In thermal equilibrium
metal abundances are expected to set the nebular electron temperature with high
abundances producing low temperatures. Our HII region distribution covers a
large range of Galactocentric radius (5 to 22 kpc) and samples the Galactic
azimuth range 330 degree to 60 degree. Using our highest quality data (72
objects) we derived an O/H Galactocentric radial gradient of -0.0383 +/- 0.0074
dex/kpc. Combining these data with a similar survey made with the NRAO 140 Foot
telescope we get a radial gradient of -0.0446 +/- 0.0049 dex/kpc for this
larger sample of 133 nebulae. The data are well fit by a linear model and no
discontinuities are detected. Dividing our sample into three Galactic azimuth
regions produced significantly different radial gradients that range from -0.03
to -0.07 dex/kpc. These inhomogeneities suggest that metals are not well mixed
at a given radius. We stress the importance of homogeneous samples to reduce
the confusion of comparing data sets with different systematics. Galactic
chemical evolution models typically derive chemical evolution along only the
radial dimension with time. Future models should consider azimuthal evolution
as well.Comment: Accepted for publication in Ap
