The phenotypic of durian plant (Durio zibethinus Murr.) in Tapanuli Tengah Regency, North Sumatra, Indonesia

Durian is a plant that is prone to genetic erosion. Exploration and characterization must be carried out to protect the local durian germplasm in Tapanuli Tengah Regency. This study aims to characterize the morphology of durian plants and determine the genetic relationship between the accessions of local durians in Tapanuli Tengah Regency. The research was done at Tukka, Sitahuis, and Kolang districts from December 2018 to February 2019 with a survey method using durian descriptor of IPGRI. Sampling techniques using purposive sampling with location judgment and morphological observation data were processed using NTSYS-pc 2.02 software and genetic relationship using the IBM SPSS (Statistical Package for the Social Sciences) program version 2.02 with cluster analysis. The result of the research showed that in Tukka, Sitahuis and Kolang district there were 75 accessions of durian been identified. The closest relationship is obtained on A61 and G71 originating from Kolang District with a similarity value of 7,345. The furthest relationship was obtained from A1 and A25 from Tukka district with the similarity value of 94,097.

Visual Analysis Algorithm or Sports Injury Intervention Effect from the Perspective of Sports Biomechanics

Using visualization technology to judge the effect of sports injury intervention under the key parts of sports injury is a cutting-edge technology. On this basis, the visual analysis algorithm of sports injury intervention effect from the perspective of sports biomechanics is proposed. On the basis of analyzing the characteristics of sports biomechanics injury, real-time monitoring of the change of sports injury posture was carried out, and the intervention information was visualized to make up for the defects of sports injury intervention, effectively identify potential injuries and take corresponding preventive measures. The simulation results show that the visual analysis algorithm of sports injury intervention effect from the perspective of sports biomechanics can effectively improve the accuracy and intervention effect of sports injury location judgment, and can effectively divide the spatial distribution of the medium in the injured part, reduce the damage probability and degree, and provide guarantee for the occurrence of potential sports.

Hospital Location Selection Targeting Indonesian NHI Patients for a Sustainable Business

Finding an optimal location is a strategic decision, and an error of location judgment causes problems in the process and directly affects cost and profitability. Currently, Indonesian National Health Insurance (BPJS) program has high coverage growth in Indonesia; however, building hospitals targeting BPJS patients have faced some challenges and may lead to an unprofitable business. Therefore, location selection is a crucial aspect of a hospital’s operation, highly relates to profitability, and impacts business performance. Moreover, being profitable is not enough for businesses to survive in the long run; they have to be sustainable. The purpose of this study is to develop a reference for a location selection for healthcare management when building hospitals targeting BPJS patients. This paper utilizes the EGSEE framework for a sustainable business to evaluate comprehensive hospital location selection sub-factors. The study employs a systematic literature review and a modified Delphi method to examine the experts’ judgment. Finally, the Analytic Hierarchy Process is applied to develop the evaluation method. The result, social factor has the highest priority with a total weight of 42%, followed by economic factor (38%), and environment factor (20%). Besides hospital targeting BPJS patients have a sustainable business by being social, hospitals also contribute to increase the welfare of people living near the facility.

Investigating the uncanny valley for prosthetic hands

Background: In 1970, Mori hypothesised the existence of an ‘uncanny valley’, whereby stimuli falling short of being fully human are found to be creepy or eerie. Objectives: To investigate how eerie people find different prosthetic hands and whether perceptions of eeriness can be accounted for by categorical ambiguity. Study design: Students participated in computerised experiments during which photographic images of hands were presented. Methods: We compared photographs of prosthetic hands pre-selected as more (H+) or less human-like (H–), as well as mechanical and real hands. Participants rated the hands for eeriness and human-likeness, as well as performing a speeded classification (human/non-human) and location judgment (control) task. Results: The H– prosthetic hands were rated as more eerie than the H+ prosthetic, mechanical and real hands, and this was unaffected by hand orientation. Participants were significantly slower to categorise the H+ prosthetic hands compared to the H– prosthetic and real hands, which was not due to generally slower responses to the H+ prosthetic hands (control task). Conclusion: People find prosthetic hands to be eerie, most consistently for less human-like prosthetic hands. This effect is not driven by ambiguity about whether to categorise the prosthetic hand as human or artificial. Clinical relevance More obviously artificial, less-realistic, prosthetic hands consistently generate a sense of eeriness, while more realistic prosthetic hands avoid the uncanny valley, at least on initial viewing. Thus, greater realism in prosthetic design may not always incur a cost, although the role of movement and cutaneous input requires further investigation.

Qualitative Analysis and Quantitive Account for Tunnel Fire Location

Fire is one of the major hazards in coal mines. After the fire broke out.the primary task of disaster rescue is to judge the location of fire and it is the prerequisite of analyzing the combustion state, the base of fire prediction. In this paper, the method of tunnel fire location judgment combining with qualitative and quantitative analysis is used, it includes the qualitative analysis basing on sets theory and quantitative analysis on fuzzy clustering. The potential location can be conversely reasoned by the warning sensors and the scope can be narrowed down widely. On this basis, the distance and similarity between the veritable time difference and the numerical simulation difference are calculated and by the value we can know the site of the fire.

Direction and Location Are Not Sufficient for Navigating in Nonrigid Environments: An Empirical Study in Augmented Reality

Nonrigid environments, such as the human colon, present unique challenges in maintaining spatial orientation during navigation. This paper presents a design concept for presenting spatial information in an augmented reality (AR) display, together with results of an experiment conducted to evaluate the relative usefulness of three types of spatial information for supporting navigation and spatial orientation in a nonrigid environment. Sixteen untrained subjects performed a simulated colonoscopy procedure, using rigid and nonrigid colon models and six different AR displays comprising various combinations of direction, location, and shape information related to the scope inside the colon. Results showed that, unlike navigating in rigid environments, subjects took 44% longer to navigate the nonrigid environment and were less efficient, and suggested that it may be useful to train aspiring endoscopists in an equivalent rigid environment initially. A navigational aid presenting shape information was more beneficial than location or direction information for navigating in the nonrigid environment. Even though the AR navigational aid display did not speed up travel time, navigation efficiency and confidence in direction and location judgment for all subjects were improved. Subjectively, subjects preferred having shape information, in addition to position and direction information, in the navigational aid.
