Abstract Puger sub-district is categorized as a tsunami-prone area because of its location in the South Coast, directly facing the Indian Ocean, which is the meeting point for two active tectonic plates. The active plate zone is prone to causing earthquakes that raise tsunamis. This article will describe the tsunami hazard and vulnerability level in Puger sub-district using the Geographic Information System (GIS) application. The method in this study uses a weighted overlay method. The weighting method is carried out to determine the level of tsunami hazard and vulnerability by following the weighting criteria in previous studies. Physical vulnerability criteria include land elevation, slope, beach type, land use, coastline distance, and rivers. The tsunami hazard level is determined based on the tsunami run-up map from previous studies. Based on the results of the risk mapping, it was found that there were five risk categories in Puger sub-district, namely the very low level (13.90 Ha), low level (271.99 Ha), medium level (7133.25 Ha), high level (644.22 Ha), and very high level (23.29 Ha).

Tsunami Run Up

Abstract. Tsunami run-up is a key value to determine when calculating and assessing the tsunami hazard in a tsunami-prone area. Run-up is accurately calculated by means of numerical models, but these models require high-resolution topobathymetric data, which are not always available, and long computational times. These drawbacks restrict the application of these models to the assessment of small areas. As an alternative method, to address large areas, empirical formulae are commonly applied to estimate run-up. These formulae are based on numerical or physical experiments on idealized geometries. In this paper, a new methodology is presented to calculate tsunami hazard at large scales. This methodology determines the tsunami flooding by using a coupled model that combines a nonlinear shallow water model (2D-H) and a volume-of-fluid model (RANS 2D-V) and applies the optimal numerical scheme in each phase of the tsunami generation-propagation-inundation process. The hybrid model has been widely applied to build a tsunami run-up database (TRD). The aim of this database is to form an interpolation domain with which to estimate the tsunami run-up of new scenarios without running a numerical simulation. The TRD was generated by simulating the propagation of parameterized tsunami waves on real non-scaled profiles. A database and hybrid numerical model were validated using real and synthetic scenarios. The new methodology provides feasible estimations of the tsunami run-up; engineers and scientists can use this methodology to address tsunami hazard at large scales.

Bali is one of the areas prone to earthquakes and tsunamis because it is located in the meeting area of ??two plates namely the Eurasian and Indo-Australian plates located in the south of Bali and a back-arc trust zone located in the north of Bali. Research has been carried out on tsunami hazard level analysis based on scenario modeling and earthquake seismicity in southern Bali. This study uses earthquake data in January 2010 - July 2018. Tsunami prone areas in southern Bali are Klungkung district, Nusa Penida, Kuta beach, Sanur beach, Tabanan and Gianyar districts. The research conducted aims to determine the level of tsunami hazard by looking at the tsunami run up and arrival time in the southern region of Bali. This simulation model uses 1427 data which is then processed using Generic Mapping Tools (GMT) software so that seismicity maps are obtained, and tsunami modeling uses the Tsunami Observation and Simulation Terminal (TOAST) software. The results obtained from the tsunami modeling simulation in the form of altitude (run up) and tsunami wave arrival time (arrival time) which have an average value of 1,385 - 2,776 meters with an arrival time of 20-24 minutes. The tsunami hazard level is obtained in scenario A with a magnitude of 7.5 which has a maximum value of <1 meter (low) and scenario B with a magnitude of 7.8 has a maximum tsunami run-up value of 1-3 meters (medium) and in scenario C with a magnitude 8.0 has a maximum run-up of tsunami waves of 1 - 3 meters (medium).

The nodes and links in urban networks are usually presented in a two-dimensional(2D) view. The co-occurrence of nodes and links can also be realized from a three-dimensional(3D) perspective to make the characteristics of urban network more intuitively revealed. Our result shows that the external connections of high-level cities are mainly affected by the level of cities(nodes) and less affected by geographical distance, while medium-level cities are affected by the interaction of the level of cities(nodes) and geographical distance. The external connections of low-level cities are greatly restricted by geographical distance.

The present study was conducted to assess the empowerment level of women in the fisheries sector in the Ganjam district of Odisha. In the inland sector, the highest numbers of women are of the fishermen population in Ganjam district i.e. 29476 out of a total 263514 number of female fisheries population of the state (Directorate of Fisheries, Government of Odisha, 2015). A very good concentration of women is involving in fisheries activities in this district. But when sector-specific cases are concerned, there are very few studies found where different dimensions of women empowerment through fisheries are discussed. The results revealed that the majority of the respondents (66.60%) in the Inland sector are grouped under a medium level of empowerment followed by low and high-level empowerment (16.70%). These results indicated that there is a significant move towards the empowerment of women in the case of inland fisheries. However, in the Marine sector equal percentage of respondents belonged to both medium and high levels of women empowerment i.e. each 30 (50.00%) and low level of empowerment was nil which indicates the level of empowerment in the marine fisheries activities compared to inland fisheries. With this background, the overall empowerment score was categorized into the low, medium, and high level of empowerment where a majority of the respondents (71.6%) were under the medium level of empowerment followed by the equal percentage of the low and high level of empowerment (14.2%). The composite score of empowerment of women is also encouraging. However, efforts are needed to bring women empowerment from medium level to a higher level. There is also a need to uplift a section of women who are still in the lower category of empowerment.

The growing complexity of the medical profession places increased demands on the future physician’s adaptive capacity. The problem of the relationship of the aff ective spectrum disorders with such a dysfunctional personality trait as perfectionism is intensively discussed in clinical psychology. Medical students are in a more diffi cult position than others. It’s related to their future profession requires a high level of training and also associated with a high responsibility for the lives and patient’s health. High pace, intense workload, stress of life makes increased demands on the compensatory mechanisms of the medical student’s psyche, failure of which leads to psychological and social confl icts. The paper presents an empirical study of the severity of symptoms of depression, anxiety, and daily stress as the main components of emotional maladaptation, depending on the level of perfectionism in the medical student environment in conditions of increased psychological stress and pre-examination stress. Subjects with a low level of perfectionism are as emotionally prosperous as possible - they have no signs of depression in 89% of cases. In the group of subjects with a medium level of perfectionism, the number of respondents in whom there are no signs of depression decreases and the number with mild, moderate and high levels of depression increases. In the group with a high level of perfectionism, the number of people without signs of depression is half of the whole group, a sharp increase in the number of subjects with moderate and high levels of depression. The level of depression in all three groups is statistically signifi cantly diff erent from each other: the lowest in the group with a low level of perfectionism and the highest in the group with a high level of perfectionism (p <0.001). Positive correlations between the general indicator of perfectionism, its separate parameters and indicators of depression, anxiety and daily stress in the studied groups are revealed. The data obtained as a result of the study confi rm the high level of emotional maladaptation of medical students. In the academic student medical environment, respondents with a pronounced level of perfectionism experience more high-intensity, daily stress (both in the interpersonal and academic spheres of student life) compared to respondents with moderate and low levels of perfectionism.

This paper discusses the effects of different innovation search scopes on the performance of the N-K fitness landscape model with a focus on its contextual factors of technology complexity and environmental turbulence. Results show that the medium-level search scope has a significantly better outcome than the low-level search scope, especially when the technological complexity is high, while the high-level search scope would not provide a statistically significant advantage. After introducing the turbulent range and rapidity into the N-K model, we extend the model into a dynamic one to simulate better the real turbulent business world. The results of the simulation in dynamic landscapes show that the higher degree of environmental turbulence causes a higher search scope to become more valuable.

Farthing (2005) tested a prediction derived from costly-signaling theory, that women would prefer physical risk takers (brave, athletic, fit) over risk-avoiders as long-term mates. Using scenarios involving high-risk acts, the prediction was confirmed for heroic (brave, altruistic) but not for non-heroic (brave, non-altruistic) acts. Apparently, women's concerns over risks to their mates overrode any positive signal value of men's risk taking, when the acts were highly risky and had no redeeming practical value. The present studies revisited the costly-signaling hypothesis using both medium- and high-risk scenarios, and it was predicted that for non-heroic acts women would prefer risk takers over risk avoiders for medium-level risks but not for highly risky acts. The prediction was supported in two studies. In Study 1, risk takers were preferred for non-heroic medium-risk acts, but risk avoiders were preferred for high-risk acts. For heroic acts, risk takers were preferred for both high- and medium-risk acts. Study 2 crossed two act risk levels with two actor skill levels, with non-heroic risks. Risk takers were preferred for the least risky combination (medium-risk act, high-skill actor) and also for the two moderately risky combinations, but risk avoiders were preferred for the riskiest combination (high-risk act, medium-skill actor). In Study 1, participants compared high-level risk takers versus risk avoiders on several person adjectives. Both heroic and non-heroic risk takers were perceived as more brave, athletic, physically fit, impulsive, attention-seeking, and foolish, and less emotionally stable and self-controlled, compared to risk avoiders. But only heroic risk takers were perceived as more altruistic, agreeable, conscientious, and sexy than risk avoiders.

La distancia que recorren los jugadores por partido supone una forma de cuantificar el volumen de carga externa del juego, y su estudio tiene una gran aplicación en la planificación del entrenamiento deportivo. El objetivo de este estudio fue analizar la distancia recorrida en diferentes fases del partido (activa y pasiva) y su relación con el número de puntos disputados y nivel de juego de los deportistas. La muestra estuvo compuesta por 108 jugadores federados de pádel (edad media = 33.81 ± 6.72 años). Se analizaron, a través de observación sistemática con el sistema SAGIT, un total 4406 puntos correspondientes a 27 partidos de pádel. Los partidos fueron divididos en tres niveles de competición: nivel alto (9 partidos; 1158 puntos), nivel medio (9 partidos; 1352 puntos) y nivel bajo (9 partidos; 1044 puntos). Los resultados mostraron como los jugadores de pádel recorren una distancia media de 11 metros por punto y de 2900 metros por partido. Esta distancia total está dividida en un 51 % de fase activa (tiempo de juego) y un 49 % de fase pasiva (tiempo de descanso). Los jugadores de nivel medio recorrieron casi 400 metros más en la fase activa que los jugadores de nivel alto y casi 900 metros más que los jugadores de nivel bajo. Además, el número de puntos disputados correlacionó de forma positiva y significativamente en la distancia recorrida por los jugadores. Abstract. Volume of game external load can be calculated through distance covered by players per match and its study has a great application in the planning of sports trainings. The aim of this study was to analyze distance covered in passive and active game phases and its relation with number of points played and players’ level. Sample was made up of 108 federated padel players (Average age = 33.81 ± 6.72 years old). A total of 4406 points corresponding to 27 padel matches were analyzed through systematic observation with the SAGIT system. Matches were divided into three levels of competition: high level (9 matches; 1158 points), medium level (9 matches; 1352 points) and low level (9 matches; 1044 points). The results showed that padel players covered an average distance of 11 meters per point and 2900 meters per game. This total distance is divided into 51% active phase (playing time) and 49% passive phase (rest time). The mid-level players recorded almost 400 meters more in the active phase than the high-level players and almost 900 meters more than the low-level players. In addition, number of points correlated positively and significantly with the distance covered by the players.
