The Content Personalization area, in digital videos domain, makes use of segmentation techniques to facilitate the processing of large data amounts while performing services as content selection or recommendation. Current researches have been directed to scene segmentation, which is based on clustering related shots. In this context, it is relevant to properly characterize shots using descriptors, because a good shot descriptor has potential to contribute to the improving of scene segmentation techniques already developed and, consequently, improve Content Personalization services. Our work aims to evaluate descriptors based on histograms for shot characterization. We present comparative results of scene segmentation by shot clustering using two approaches for shot representation: key frame and average histogram. The experiments were performed in two video domains: movies and television news. The results show that there aren't significant advantages between the approaches investigated and that they don't present good performance in assisting to identify scenes, showing the need of more research on new methods on shot representation.

The International Classification for Nursing Practice (ICNP)--Alpha Version, is the first rendition of the International Council of Nurses (ICN) efforts to develop a standardized international nursing language system. This system has three principal components: nursing phenomena; nursing actions; and nursing outcomes. This article describes a study of agreements between terms used by nurses of the intensive care unit at the Hospital of the University of Sao Paulo, to designate patients' nursing problems and the terms proposed by the ICNP--Alpha Version. The records of 59 interned patients, admitted to the intensive therapy unit, were analysed for nursing problems. Of 336 problem categories listed by the nurses, 153 (45.5%) corresponded to the ICNP terms. The 183 categories of problems that did not correspond to the ICNP terms were categorized by the authors as the following: medical diagnoses (37.2%); signs (28.4%); interventions (26.2%); and historical data (8.2%). These results show that there may be no agreement between the concept of nursing phenomena for the ICNP and of nursing problems for the nurses whose records were analysed. Considering that medical diagnoses, intervention and historical data could not be accepted as nursing phenomena for the ICNP, the agreement is potentially higher than 45.5%.

Smoking is a public health problem associated with high morbimortality. Smoking cessation services, although effective, have limited reach and have been compromised by the pandemic. This study aimed to analyze the care for smokers in João Pessoa (PB), Brazil, during the COVID-19 pandemic. A descriptive, exploratory, and quantitative study was conducted in two phases: a survey of health indicators and an evaluation of sociodemographic profiles of professionals and service clients during the study years. Seven professionals, smoking group coordinators, and 20 clients participated in the research. The results showed low program coverage, with a declining number of smokers treated during the pandemic, down from 419 in 2019 to 129 in 2020. Interviews identified the program’s positive aspects and limitations, good effectiveness, and low access, especially in primary health care. Tobacco consumption and risk reduction strategies during the COVID-19 pandemic originated from services and professionals involved. We can conclude that the National Tobacco Control Program has an incipient implementation in primary health care in this region and that the number of services offered was reduced during the pandemic, decreasing demand and actions.
