Assessment of potential locations for evacuation in Depok Municipality using images from UAV

This study aims to perform assessment of public facilities in Perumnas Depok Utara, Depok Municipality, Indonesia for evacuation locations using images from UAV. A UAV device, a DJI Phantom 4 was flown at 100 metres height to capture seven locations of public facilities located within Perumnas Depok Utara residential area. Raw images from DJI Phantom 4 underwent image processing and georeferencing process to generate smooth aerial images. Public facilities locations were identified from acquired images and later digitized to generate layers of assessment parameters. Each locations were scored based on rating of all criteria’s parameters. Seven criteria serve as foundation layers for evacuation assessment namely size, ownership, availability, capacity, infrastructure, transportation and safety. Study result shows that Jawa Soccer Field is the first rank of potential evacuation location while Balai Rakyat Meeting Place is the least potential evacuation location. Total area for potential evacuation locations around 43,000 m2 and can accommodate 28,961 people or equal to 60.5% of Beji Village’s population.

Perbandingan latihan resistance dan ladder untuk meningkatkan kecepatan lari pemain futsal SMA N 3 Pemalang

This research is motivated by the physical condition of the running speed of the extracurricular futsal team of SMA Negeri 3 Pemalang which is not good, this can be seen from the many players who do not have a maximum running speed. This study aims to determine the effect of the resistance band and ladder exercises in increasing running speed in futsal games and to find out which exercises are more effective. The research subjects sampled in the study were 16 students of SMA N 3 Pemalang who participated in futsal extracurricular activities which were divided into 2 groups, namely the first group of 8 resistance band exercises and the second group of 8 ladder exercises. Data collection was carried out with a 60-meter running speed test on the Cibelok soccer field. The research design used was a pre-test and post-test group, therefore, data collection was carriedout during the pretest and posttest. Based on the calculation results, it was found that the increase in running speed with Resistance band training was 4.95%, while with Ladder training it was 13.58%. So that Ladder training is more effective to increase running speed. The conclusion of this study is that the Ladder training method is more effective and good in increasing the running speed of futsal extracurricular players at SMAN 3 Pemalang.

Construction of maintenance staffing model for managing sports venues in comprehensive sports games: A research based on the practice of the 7th military world games

The operation and maintenance of sports venues is the basis of ensuring the orderly organization of various events in large-scale comprehensive sports games. Due to the lack of evaluation methods and an index system, it was difficult to predict the input of operating and managing sports venues in large-scale comprehensive sports games. Excessive manpower is often put to guarantee the smooth operation work, causing the problem of waste on all resources. Based on the practice of the operational work for specified sports fields during the 7th World Army Games, this paper establishes a staffing allocation model for the maintenance and operation of sports venues. On the premise of building up a clear maintenance scope, a clarified organization structure and working procedure, the maintenance index of 15 specified venues is evaluated with analytic hierarchy process (AHP), and a set of allocation criteria of the operation team is put forward. The maintenance coefficients of studied venues range from 0.08 to 0.91, and the venues with highest coefficients are the main stadium, the naval pentathlon venues and the soccer field, etc.

The Spatial Ingroup Bias: Ingroup Teams Are Positioned Where Writing Starts

In four studies, we test the hypothesis that people, asked to envisage interactions between an ingroup and an outgroup, tend to spatially represent the ingroup where writing starts (e.g., left in Italian) and as acting along script direction. Using soccer as a highly competitive intergroup setting, in Study 1 ( N = 100) Italian soccer fans were found to envisage their team on the left side of a horizontal soccer field, hence playing rightward. Studies 2a and 2b ( N = 219 Italian and N = 200 English speakers) replicate this finding, regardless of whether the own team was stronger or weaker than the rival team. Study 3 ( N = 67 Italian and N = 67 Arabic speakers) illustrates the cultural underpinnings of the Spatial Intergroup Bias, showing a rightward ingroup bias for Italian speakers and a leftward ingroup bias for Arabic speakers. Findings are discussed in relation to how space is deployed to symbolically express ingroup favoritism (Spatial Ingroup Bias) versus shared stereotypes (Spatial Agency Bias).

The Moral Gatekeeper: Soccer and Technology, the Case of Video Assistant Referee (VAR)

Video assistant referee was officially introduced into soccer regulations in 2018, after many years in which referee errors were justified as being “part of the game.” The technology’s penetration into the soccer field was accompanied by concerns and much criticism that, to a large degree, continues to be voiced with frequency. This paper argues that, despite fierce objections and extensive criticism, VAR represents an important revision in modern professional soccer, and moreover, it completes a moral revolution in the evolution of the sport as a whole. Theoretically speaking, this technology enables an improvement in the sport’s professional standards and its public image and prestige, and especially its moral standards – Fair play. Furthermore, the introduction of this technology makes it possible to discover additional weaknesses (Standardization for extra time, a clear definition of a handball offense and more) that professional soccer regulations will probably be forced to address in the future.

Sports infrastructure for football in Częstochowa in the interwar period

The article presents the sports infrastructure for football in Częstochowa in the interwar years. The article was written mainly on the basis of archival and press sources. The conducted research shows that in Częstochowa in the interwar period, several sports facilities adapted to playing foot-ball were built. Both the quantity and quality, compared to the national scale, was insufficient. Investors in sports infrastructure were municipal governments, the army andstate authorities. Sports clubs and associations also tried to create sports facilities. In Częstochowa, the first munic-ipal soccer field was opened in 1923 in the ‘Zawodzie’district. A representative sports facility of regional importance was put into operation in the early 1930s. The “Ogniska Obrony Niepod-ległości” Stadium named after Marshal Józef Piłsudski was considered to be one of the leading ones in the ‘Kielce’Province. However, it could not compete with the best facilities in Poland in terms of infrastructure. A national and international stadium could be a facility that was to be built atOlsztyńska street. Despite the commenced works, the investment was not completed due to lack of money and the outbreak of World War II. In the years 1918-1939, several pitches for the football discipline were built. Local sports clubs were mostly responsible for them.

CNN-Based Self Localization Using Visual Modelling of a Gyrocompass Line Mark and Omni-Vision Image for a Wheeled Soccer Robot Application

The Convolutional Neural Network (CNN) is an object classification method that has been widely used in recent research. In this paper, we propose CNN for use in the self-localization of wheeled soccer robots on a soccer field. If the soccer field is divided into equally sized quadrants with imaginary vertical and horizontal lines intersecting in the middle of the field, then the soccer field has an identical shape for each quadrant. Every quadrant is a reflection of the other quadrants. Superficially similar images appearing in different positions may result in positioning mistakes. This paper proposes a solution to this problem by using a visual modelling of the gyrocompass line mark and omni-vision image for the CNN-based self-localization system. A gyrocompass is used to obtain the angle of the robot on the soccer field. A 360° omni-vision camera is used to capture images that cover all parts of the soccer field wherever the robot is located. The angle of the robot is added to the omni-vision image using the visual modelling method. The implementation of self-localization without visual modelling gives accuracy rates of 0.3262, and this result is increased to 0.6827 with the proposed methods. The experiment was carried out in the robotics laboratory of the Institut Teknologi Sepuluh Nopember (ITS) with the ITS Robot with Intelligent System (IRIS) robot.
