Sports facilities are the material basis for people to participate in physical exercise. The construction of facilities is conducive to improving people’s health and their expectations for a happy life. Sports facilities are part of the infrastructure. The reasonable layout of sports facilities is conducive to shortening the gap between urban and rural areas, achieving common economic prosperity, and promoting social harmony and unity. Public sports facilities are of great significance to urban construction and people’s daily lives. Based on big data and machine vision, this document constructs a big data model framework for urban public sports and leisure facilities, quantifies the diversity and overall coordination of sports facilities, and conducts simulation experiments on the designed urban leisure and sports public facility model. The experimental results show that compared with the traditional method, this method effectively improves the coverage of urban leisure and sports public facilities, and the space utilization rate is increased by 15.32% compared with the traditional method, which maximizes the use of regional space and makes it more convenient for urban residents. It can carry out physical exercise quickly and improve the quality of life of residents.

The Impact

The layout of public service facilities and their accessibility are important factors affecting spatial justice. Previous studies have verified the positive influence of public facilities accessibility on house prices; however, the spatial scale of the impact of various public facilities accessibility on house prices is not yet clear. This study takes transportation analysis zone of Wuhan city as the spatial unit, measure the public facilities accessibility of schools, hospitals, green space, and public transit stations with four kinds of accessibility models such as the nearest distance, real time travel cost, kernel density, and two step floating catchment area (2SFCA), and explores the multiscale effect of public services accessibility on house prices with multiscale geographically weighted regression model. The results show that the differentiated scale effect not only exists among different public facility accessibilities, but also exists in different accessibility models of the same sort of facility. The article also suggests that different facilities should adopt its appropriate accessibility model. This study provides insights into spatial heterogeneity of urban public service facilities accessibility, which will benefit decision making in equal accessibility planning and policy formulation for the layout of urban service facilities.

Resumen: En España, en la primera década del régimen de 1978 las políticas deportivas se implementaron con un fuerte contenidos social, mejorando las instalaciones públicas dentro de un proceso de democratización del deporte. Posteriormente, en los primeros 1990s, Europa liberalizó los mercados y se apostó por invertir en la alta competición, construir grandes estadios y organizar mega-eventos. España potenció esa política y ello permitió el éxito deportivo de muchos atletas españoles que se integraron en la elite mundial. Contradictoriamente, hubo un aumento del ejercicio físico entre la población como recreación y por razones de salud, más que por competir, y que no tenían una oferta pública adecuada  para realizar su actividad. Esta necesidad popular no fue resuelta por las políticas deportivas ni en Europa ni en España. La metodología de la investigación se basó en la investigación cuantitativa y el análisis comparativo. Los datos analizados proceden de fuentes oficiales y series históricas.Abstract: In Spain, in the first decade of the 1978 regime, sports policies were implemented with a strong social content, improving public facilities within a of democratization process. Subsequently, in the early 1990s, in an international context of market liberalization, the Spanish governments began investing in high competition, building large stadiums and organizing mega-events. There was a sporting success of many Spanish athletes who were integrated into the world elite. Contradictorily, there was an increase in physical exercise among the population, as recreation and for health reasons, rather than competing. But this popular demand was not resolved by sports policies. The methodology was based in quantitative research and comparative analysis. The data analyzed come from official indirect sources using historical series.

ABSTRACT Northern Sanur Beach (Sanur Kaja Beach) consisting of Matahari Terbit Beach and the main Sanur Beach is a polular tourist destination on the island of Bali. Its strategic location, famous history, public and additional facilities, makes Sanur a demanding location for tourists. But one important role for such tourist destination is the cleanliness of the beach itself, providing comfort to travellers. A direct observational study and a descriptive cross-sectional study with randomized survey of 100 travellers (50 domestic and 50 international) regarding the cleanliness of Northern Sanur beach. Through the survey we gathered traveller’s evaluation on current sanitation of public facility (toilet, parking, and resting), additional facilities (restaurant, gift shop, and street vendors), and sanitary facility (rubbish bins) condition in Northern Sanur beach giving a score of very clean, moderate, or poor. Through direct observational we looked at physical objects around the environement such as its geography and facilities available in Northern Sanur beach collected through interviews from local informans. Respondents showed an overall positive response of “moderate” 25 of respondents or (50%) of domestics, and 32 respondents or (64% ) foreigners regarding sanitation quality of Northern Sanur beach. Public facilities as well as additional facilities are generally considered to be moderately clean by the total respondents. But traveller’s opinion suggested the “poor” availability of rubbish bins 25 of respondent or (50%) domestics and 23of respondents or  (46%) foreigners. Public facilities of four public toilets, two parking area, rubbish bins, are available for travellers and taken care by local employees assigned by the head of village. As travellers states Northern Sanur to be moderately clean, other results that are considered poor or below expectation regarding specific public facilities should be taken care of to provide a better tourist attraction. Cleanliness is a tourist attraction itself, therefore keeping clean it is important for the sustainability of tourism.

Abstract This article explores the spatial differentiation and integration between the post-disaster victims and the indigenous peasants 8 years after a rapid off-site resettlement oriented by governments in New Beichuan. Data were broadly collected from placement documents, questionnaires, interviews and site measurement by empirical research and on-site investigation in 2014. The resettlement plan was introduced and analyzed for housing resettlement, open space systems, public facilities allocation and resettlement policies. Based on statistical analysis of the questionnaire data and observation on the usage of the built environment, problems with the spatial usage and mismatches between the specific spatial requirements and subjective planning intention of integration are analyzed and preliminary findings are shown. The results showed that the excessive pursuit of speed and deficiency in economically self-sustaining efforts might contribute to insufficient attention given to spatial, social and economic aspects and leads to inevitable and long-standing problems, such as housing quality problems, neighborhoods management and security concerns, contradictions between the housing layout and local living habits, different spatial usage preferences between the indigenous peasants and post-disaster migrants, and disequilibrium of public facility allocation.

Third-hand smoke (THS) causes pathological changes in the liver, lungs, and skin. THS exposure can be ubiquitous, chronic, and unconscious. However, little is known about THS exposure in public facilities and its susceptible population. This paper aimed to identify which public facilities and socio-demographic groups were especially vulnerable to THS. Data from 1360 adults obtained from Korean National Environmental Health Survey I (2009–2011) were analyzed. To study the sole effect of THS, we restricted the study population to those participants who had never smoked and who had no exposure to second-hand smoke. The assessed variables included the type and frequency of public transportation, frequency of use of 12 different public facilities, and 8 socio-demographic factors. Urinary cotinine was used as a biomarker. T-tests and analysis of variance were used for univariate analyses, while generalized linear regression was used for multivariate analysis. Frequent use of public transportation, bars, internet cafés, and participants with low levels of education, divorced or bereaved, living in multi-unit houses, and with smokers within the family were associated with significantly high urinary cotinine levels. These findings indicate that the frequent use of public transportation, certain public facilities and certain socio-demographic factors can result in high THS exposure.

Considering the confidentiality and integrity of big data in cloud storage, a MapReduce-based AES parallelization scheme is designed by using MapReduce framework of the open source Hadoop in this paper. The scheme takes full advantage of MapReduce and modern cryptography technologies to parallelize AES encryption and decryption process, in the way of data decomposition, which speeds up the efficiency in the implementation of encryption and decryption. Meanwhile, mix plaintext, separate storage and other technical means are taken into account in this scheme to ensure the confidentiality and security of the key and the ciphertext. By analyzing the performance, it is proved that the time consumption of new scheme is significantly reduced comparing with the traditional method.

Most fixed automations in traditional manufacturing systems are not equipped to manage product variations efficiently. This paper presents a design and configuration for a machine-vision-equipped robotic packing cell that is capable of managing a wide range of product sizes. Product size information is gathered at an earlier stage in the manufacturing process and then transferred electronically to the robot cell. Different controllers are needed to manage robot cell functions related to incoming product, machine vision, robot control, robot manipulator, and multiple layers of safety control information. Each controller, due to the nature of its function, has different advantages in processing different data types. In order to achieve the highest possible robot manipulator utilization rate, the assignment of information processing among controllers needs to be thoughtfully planned, especially for the critical mathematical routines. Coordination and calibration between charged-coupled device (CCD) cameras and robots in existing manufacturing facilities are configured with considerations for building vibrations, lighting conditions, and signal processing assignments among the available devices. System efficiency is improved when the vision signal, robot logical signal, and robot manipulator signal processing units are running cohesively in parallel. The capability of the machine-vision-assisted robot end effector automatic path adjustment, to pick up and pack different sizes of products dynamically, allows a higher level of flexibility and efficiency. This paper describes a feasible design and configuration for an integrated machine vision robotic cell in a manufacturing system.
