As a consequence of the 1985 Mexico City earthquake, the authorities of the city have decided to evaluate the seismic capacity of the buildings without damage with the purpose of detecting those with the most vulnerability, in order to take the preventive actions necessary to improve the security of the citizens in future earthquakes. Based on the census of the structures of the city, the procedure of evaluation used considers three levels of increasing precision permitting a progressive selection of the buildings in bad condition. Work is now under process in the main districts of the city with good results.

Resistance Coefficients

Using a simplified method for the evaluation of the seismic capacity of medium rise concrete structures, it was possible to obtain the base shear coefficient corresponding to failure (resistance coefficient) for 162 buildings, and use it as an evaluation index. The resistance coefficients of the 90 evaluated structures that suffered severe damage were used to elaborate a map of intensities for the 1985 Mexico City earthquake. This map shows the strong interaction of neighboring zones of firm soil or rock that amplify the ground motion in the soft soil between them as much as 100%, this being the main reason for the high intensities observed in some districts of the city. Based on these results, a new seismic zoning was proposed for the chapter of the 1987 Mexico City Building Code.

The City

The earthquake that shook Mexico City on 19 September 1985, destroyed several hundred buildings and took thousands of lives. Two buildings located in the most highly damaged part of the city experienced strong shaking, but suffered only slight damage. These reinforced concrete frame buildings had been retrofit with steel bracing systems and infill reinforced concrete walls prior to the earthquake. Forced vibration tests, analytical studies and geotechnical investigations for each building have been conducted. The results indicate that the steel bracing systems strengthened the buildings and stiffened them, moving their natural periods away from the 2.0-second predominant ground period in that part of the city. Implications for the design of strengthening systems have been determined.

The September 19, 2017 intraslab earthquake (Mw7.1), whose epicenter was located near the limits between the states of Puebla and Morelos at approximately 120km from Mexico City, caused severe damage in these regions. In Mexico City more than 40 buildings collapsed, and hundreds had moderate to severe damage; dozens of them are to be demolished. This article analyzes the spectral ratios of accelerometric stations in the lake-bed of Mexico City with respect to the average Fourier spectra at hill zone sites in order to study and compare over time the changes in the behavior of local effects and their relationship with the damage presented during this earthquake; these ratios exhibit also the settlement problem in some places in the city due to over exploiting the aquifer for water supply purposes. Finally, pseudoacceleration and hysteretic energy maps for Mexico City with a discussion with a possible correlation with reported damages are presented.

The rapid development of information and technology, the city of Bandung tourism has also increased. However, tourists who visit the city of Bandung have problems with a limited time when visiting Bandung tourist attractions. Traffic congestion, distance, and the number of tourist destinations are the problems for tourists travel. The optimal route selection is the solution for those problems. Congestion and distance data are processed using the Simple Additive Weighting (SAW) method. Route selection uses the Floyd-Warshall Algorithm. In this study, the selection of the best route gets the smallest weight with a value of 5.127 from the Algorithm process. Based on testing, from two to five tourist attractions get an average calculation time of 3 to 5 seconds. This application is expected to provide optimal solutions for tourists in the selection of tourist travel routes.

This article aims to encourage the interdisciplinary study of ‘languaculture,’ an approach to language and culture in which ideology, linguistic and cultural forms, as well as praxis are studied in relation to one another. An integrated analysis of the selection of linguistic and cultural elements provides insight into how these choices arise from internalized norms and values, and how people position themselves toward received categories and hegemonic ideologies. An interdisciplinary approach will stimulate a rethinking of established concepts and methods of research. It will also lead to a mutual strengthening of linguistic, sociolinguistic, and anthropological research. This contribution focuses on Limburg and the linguistic political context of this Southern-Netherlands region where people are strongly aware of their linguistic distinctiveness. The argument of the paper is based on a case study of languaculture, viz. the carnivalesque song ‘Naar Talia’ (To Italy) by the Getske Boys from the city of Heerlen.

"The City of Oslo in Jan Erik Vold’s Poems. The aim of this paper is to examine, from a cultural and social perspective, the Norwegian urban areas and everyday situations in Jan Erik Vold’s (b. 1939) poems. Our close-reading technique reveals important social aspects, different places and streets, located in the capital city of Norway, Oslo. These urban poems written by the contemporary Norwegian poet Jan Erik Vold contribute to the reconstruction of a new Norwegian cultural identity as it is reflected in a selection of poems taken from Mor Godhjertas glade versjon. Ja (Mother Goodhearted’s Happy Version. Yes, 1968), followed by the poet’s wanderings in the city of Oslo in En som het Abel Ek (One Named Abel Ek, 1988), and concluding with his bitter social criticism in Elg (Moose, 1989) and IKKE. Skillingstrykk fra nittitallet (Not: Broadsides from the Nineties, 1993). Vold’s urban poems emphasise the transition from nyenkle (new simple), friendly and descriptive poems which present closely the city of Oslo on foot, to short, political and social critical poems from the 90s. Thus, it is of great importance to traverse various urban ‘landscapes’ in different periods of time, beginning with the 1960s, followed by the 80s and the 90s. Keywords: Jan Erik Vold, urban poems, social criticism, Norwegian urban areas, the city of Oslo "

OBJECTIVE: To characterize deaths from pulmonary tuberculosis, according to sociodemographic and operational variables, in the city of São Luís, Brazil, and to describe their spatial distribution. METHODS: This was an exploratory ecological study based on secondary data from death certificates, obtained from the Brazilian Mortality Database, related to deaths from pulmonary tuberculosis. We included all deaths attributed to pulmonary tuberculosis that occurred in the urban area of São Luís between 2008 and 2012. We performed univariate and bivariate analyses of the sociodemographic and operational variables of the deaths investigated, as well as evaluating the spatial distribution of the events by kernel density estimation. RESULTS: During the study period, there were 193 deaths from pulmonary tuberculosis in São Luís. The median age of the affected individuals was 52 years. Of the 193 individuals who died, 142 (73.60%) were male, 133 (68.91%) were Mulatto, 102 (53.13%) were single, and 64 (33.16%) had completed middle school. There was a significant positive association between not having received medical care prior to death and an autopsy having been performed (p = 0.001). A thematic map by density of points showed that the spatial distribution of those deaths was heterogeneous and that the density was as high as 8.12 deaths/km2. CONCLUSIONS: The sociodemographic and operational characteristics of the deaths from pulmonary tuberculosis evaluated in this study, as well as the identification of priority areas for control and surveillance of the disease, could promote public health policies aimed at reducing health inequities, allowing the optimization of resources, as well as informing decisions regarding the selection of strategies and specific interventions targeting the most vulnerable populations.

Aims: To evaluate the understanding of drug prescriptions by patients, comparing the user self-report with the researcher assessment.Methods: A cross-sectional study was conducted from November 2013 to February 2014 at a Basic Health Unit in the city of Belo Horizonte, Minas Gerais, Brazil. Users 18 years of age or older who sought medicines in the unit's pharmacy, for themselves or for minors under their care, were interviewed. The selection of the sample was non-probabilistic, for convenience. During the interview, the users informed if they had understood the following data of the prescriptions: drug name, dose and frequency of administration. Participants then repeated the data for researchers, being allowed to check the prescriptions at the same time. After the interviews, the answers to the questions were interpreted by the researchers, who evaluated the agreement between the information provided by the users and the actual instructions of the recipes, using the Kappa test.Results: Data were collected from 69 users of the unit's pharmacy (corresponding to 69 delivered prescriptions). Fifty-nine (85.5%) users reported having understood all the prescriptions data (self-report), while according to the measurement of the researchers, 23 (33.3%) were the respondents who simultaneously understood all data, relating to the name of the drug, number of daily doses and schedule. Kappa test indicated a degree of agreement between self-report and measurement of researchers of 0.138 (slight) considering all items of the prescription, and specifically on the number of doses the agreement was -0.055 (poor).Conclusions: Self-reported rate of patient's understanding of drug prescriptions was higher than the assessed by the researchers. This result suggests that self-report of patients with respect to the understanding of prescriptions has limitations and should be interpreted with caution both in research and in clinical practice. It is recommended to enhance the means of providing information to patients, in order to contribute to the proper understanding of drug prescriptions.
