Predicting the effect of decompression sickness on survival following submarine tower escape

Purpose The purpose of the present study was the development of a methodology for translating predicted rates of decompression sickness (DCS), following tower escape from a sunken submarine, into predicted probability of survival, a more useful statistic for making operational decisions. Design/methodology/approach Predictions were made, using existing models, for the probabilities of a range of DCS symptoms following submarine tower escape. Subject matter expert estimates of the effect of these symptoms on a submariner’s ability to survive in benign weather conditions on the sea surface until rescued were combined with the likelihoods of the different symptoms occurring using standard probability theory. Plots were generated showing the dependence of predicted probability of survival following escape on the escape depth and the pressure within the stricken submarine. Findings Current advice on whether to attempt tower escape is based on avoiding rates of DCS above approximately 5%–10%. Consideration of predicted survival rates, based on subject matter expert opinion, suggests that the current advice might be considered as conservative in the distressed submarine scenario, as DCS rates of 10% are not anticipated to markedly affect survival rates. Originality/value According to the authors’ knowledge, this study represents the first attempt to quantify the effect of different DCS symptoms on the probability of survival in submarine tower escape.

Pengembangan Buku Ajar Berbasis HOTS Dimensi Taksonomi Bloom Tema 8 Subtema 1 Kelas 4

The research aimed to compile HOTS textbooks based on Bloom's Taxonomy dimensions for grade 4 students at MI Dwi Dasa Warsa. The development of this book is limited to thematic subjects, namely the theme of 8 sub-themes 1 class 4. This research is a Research and Development research with a 4-D development model approach to the Thiagarajan Model which has 4 stages, namely Define, Design, and Develop ( Development) and Disseminate (Spread). This textbook was validated by 2 material experts (subject matter expert lecturers and subject teachers), 1 media expert and 24 students who were the research objects. Textbooks were tested on 24 grade 4 students of MI Dwi Dasa Warsa. Data collection used interview techniques to subject teachers and grade 4 students. The results showed that this textbook as a whole was suitable for use as teaching materials. This is indicated by the results of the validation by the material expert lecturer with a total score (X) greater than the total comparison score (138> 104.95) and is included in the category A value (very good) and the validation results by the subject teacher with a total score ( X) is greater than the total comparison score (167> 104.95) and is in the category A score or very good. Meanwhile, the results of the validation by media experts got a total score (X) greater than the total comparison score (106> 72) which was categorized as A or very good. Validation by students with the calculation of SPSS Person Correlation shows that all scores have reached more than 0.05 and can be said to be valid

Pengembangan Buku Panduan Penggunaan Aplikasi Resertifikasi Kompetensi untuk Karyawan Perhimpunan Dokter Sepsialis Penyakit Dalam Seluruh Indonesia

This development research aims to produce a print media in the form of a guidebook to use of the Application “Resertifikasi Kompetensi KIPD”. This guidelines is meant to be used by employees Branch of PAPDI in Indonesia. This development research is referring to Rowntree’s model that consists of three major stages; planning; preparation of writing; writing and editing. The evaluation on this development research was conducted through expert review and one-to-one evaluation. The evaluation involving one subject matter expert, one media expert, and five users. The average value obtainded from the expert review by the subject matter expert was 3,46 overall excellent. The average value obtainded from the expert review by the media expert was 2,56 overall good. In one-to-one evaluation, obtained the average score 3,4 which signifies the overall guidance is excellent and can be used to guide the employees Branch of PAPDI to using the Application “Resertifikasi Kompetensi KIPD” correctly and precisely.

Profiles, Proxies, and Assumptions: Decentralized, Communications-Resilient Planning, Allocation, and Scheduling

Degraded communications are expected in large-scale disaster response and military operations, which nevertheless require rapid, concerted actions by distributed decision makers, each with limited visibility into the changing situation and in charge of a limited set of resources. We describe LAPLATA, a novel architecture that addresses these challenges by separating mission planning from allocation/scheduling for scalability but at the cost of some negotiation. We describe formal algorithms that achieve near-optimal performance according to mission completion percentage and subject matter expert review: assumption-based planning and replanning, profileassisted cooperative allocation, and schedule negotiation. We validate our approach on a realistic problem specification and compare results against subject matter expert solutions.
