Optimization of Maritime Search and Rescue Resources Selection Based on Response Threshold Ant Colony Algorithm
Authors: Mao Jiahui , Guo Yu , Yang Qingqing , Gao Yingying , Yang Kewei
Published: August 2022

The timeliness and severity of maritime search and rescue (MSAR) determine that the resource selection should be fast and optimized as much as possible. At present, there is no intelligent optimization method to assist decision-making, which is suitable for the actual characteristics of MSAR. In this paper, the optimization problem of MSAR resource selection is abstracted into a multi-objective optimization problem. Considering the needs of actual MSAR resources, the response threshold model is introduced to improve the ant colony algorithm. It can effectively solve the situation that the ordinary optimization algorithm is easy to fall into the local optimal solution and ignore the better resources. The research work of this paper is divided into three parts: model construction, model solution and model verification. Firstly, a multi-objective optimization model with five practical constraints is constructed to minimize the search time and maximize the average utility of resources. Then, the response threshold model considering the actual resource demand is used as the heuristic information in the ant colony algorithm. The stimulus model and threshold model in the response threshold model represent the ability of resources to perform tasks and the threshold of resources to perform tasks respectively, so as to improve the efficiency and speed of the algorithm. Finally, the algorithm is verified and compared through an example. The experimental results show that the average resource utility of this algorithm is 20.6% higher than that of the basic ant colony algorithm, and the MSAR success rate is also improved, which verifies the effectiveness of this method.

Meteorological big data has a wide geographical range, large space-time density, many data types and strong timeliness. It has become the requirement of the development of meteorological industry to quickly extract huge information and knowledge from big data to solve the problem of weather prediction. Based on the measured data of maximum one-hour rainfall from six representative rainfall stations in Wuhan from 1992 to 2021, the variation law, characteristic analysis and return period of different aging precipitation in Wuhan city in the past 30 years are analyzed. The results show that although the number of days of precipitation in Wuhan has increased year by year in the past 30 years, the days of rainstorm and more than rainstorm generally show a decreasing trend. The precipitation is mainly concentrated in spring (March-May) and summer (June-August), with the most in summer. The monthly precipitation is mainly concentrated in July, with the least precipitation in December. The maximum daily precipitation is between 55.1∼285.7mm, and the average maximum hourly precipitation of 122.4mm reaches 98.6mm. At last, based on the parameters of GEV distribution, the maximum hourly precipitation, maximum 3h, 6h, 12h, 24h precipitation, continuous hourly precipitation, maximum daily precipitation and maximum continuous daily precipitation are fitted, and the values of different recurrence periods are estimated.

Published: August 2022

In order to study the wind flow field and dust transport law of the comprehensive mining work surface, taking the 21103 comprehensive mining working surface of Hulusu Coal Mine as the research object, SolidWorks was used to establish the comprehensive mining working surface model, and the comprehensive mining working surface under different inlet wind speed conditions was simulated and analyzed by Fluent. The results show that due to the existence of the high-speed wind flow belt, dust is mainly distributed near the downwind side working surface; when the inlet speed is 2.5m/s, the dust mass concentration of the comprehensive mining working surface is low and it is not easy to cause secondary dust, which is the optimal inlet speed; the dust distribution within 10m of the downwind side of the shearer is the most, which is the key area of dust prevention and control.
Understanding Hybrid Warfare in Cyberspace: Building Resiliance Through Understanding
Authors: Brill Alan , Bennett John
Published: August 2022

The technology associated with the Internet is said to evolve at the speed of light. That is certainly true when it comes to understanding the strategies and tactics used to commit cybercrimes, whether those crimes target military, governmental or private-sector organizations, and whether the threat actors are governments, government sponsored hackers, criminal cyber-gangs or individuals. In this paper, we examine recent evolutions of cyberspace threats to move them from simple and direct to more layered complex and stealthy methodologies. For example, what appears to be a ransomware attack encrypting files with the hope of collecting a ransom payment for a decryption key may actually hide the actual theft of that data, representing an actual data compromise. Suggestions for maintaining and improving an organization’s readiness to deal with these hybrid threats are provided

Published: August 2022

Recent advances in machine learning show great potential for automatic detection of abnormalities in electroencephalography (EEG). While simple and interpretable models combined with expert-comprehensible input features offer full control of the decision making process, these methods commonly lag behind complex deep learning and feature extraction methods in terms of performance. Here we study a feasibility of a bridging solution, where deep learning is combined with interpretable input and an algorithm computing the importance of particular EEG features in the decision process. We built a convolutional neural network with multi-channel EEG frequency bands as input and investigated four different methods for feature importance attribution: Layer-wise Relevance Propagation (LRP), DeepLIFT, Integrated Gradients (IG) and Guided GradCAM. Our analysis showed consistency between the first three methods, and deviating attributions of the fourth method, suggesting the importance of using a package of methods together to ensure the robustness of medical interpretation.

Authors: Beckmann Catharina Lena , Lodde Georg , Livingstone Elisabeth , Schadendorf Dirk , Böckmann Britta
Published: August 2022

Introduction: The provision of knowledge through clinical practice guidelines and hospital-specific standard operating procedures (SOPs) is ubiquitous in the medical context and in the treatment of melanoma patients. However, these knowledge sources are only available in unstructured text form and without any contextual link to real patient data. The aim of our project is to give a modeled decision support for the next treatment step based on the actual data and position of a patient. Methods: First, we identified passages for qualified decision-making necessary at the point of care from the SOP for melanoma. Thereby, the patient-specific contextual reference data at decision points was considered in parallel and represented by FHIR (Fast Healthcare Interoperability Resource) resources. The decision algorithm was then formalized using BPMN modeling with FHIR annotations. Validation was provided by medical experts, dermatooncologists from University Hospital Essen. Results: The resulting BPMN model is presented here with the diagnostic procedure of sentinel lymph node excision as the example snippet from the whole algorithm. Each decision point is edited with FHIR resources covering the patient data and preparing the context sensitivity of the model. Conclusion: Modeling guideline-based information into a decision algorithm that can be presented at the point of care with contextual reference, may have the potential to support patient-specific clinical decision-making. For patients from a certain status like in the metastatic setting modeling becomes highly tailored to specific patient cases, alternative and individualized treatment options.
Identification of Cervical Epidural Space: A Comparison Study between Contrast Spread and Loss of Resistance Techniques
Authors: Perper Yakov
Published: August 2022

BACKGROUND AND OBJECTIVES: Early epidural space identification is critical to the efficacy and safety of cervical epidural steroid injections (CESI). Currently, the accepted method for epidural space recognition is the loss of resistance technique (LORT). I hypothesized that the contrast spread technique might recognize epidural space concurrently with or sooner than LORT and that smaller needles might be employed with the fluoroscopy-only method but not with LORT. To test my hypotheses, I conducted a comparison study.

METHODS: The study participants were patients from my practice with a clinical diagnosis of cervical radiculitis divided into two groups of 20 each, who underwent CESI with either an 18G or a 25G Tuohy needle. All CESIs were performed utilizing the fluoroscopy-only method. Then, LOR was tested using an Epidrum device that was observed for 30 seconds; if the Epidrum deflated, the result was positive.

RESULTS: LOR was positive in 12 out of 20 patients in the 18G group and 2 out of 20 in the 25G group. The 95% confidence interval test for proportion revealed a statistically significantly lower rate for epidural space detection by LORT in both groups: [0.385, 0.815] in the 18G and [-0.031, 0.231] in the 25G group. Statistical significance of the difference between groups in LOR accuracy rate (60% vs. 10%) was confirmed by z-test for independent proportions: z = 3.31 (p < 0.001), Cohen’s h = 1.13.

CONCLUSION: Fluoroscopy only method might be a safer alternative to LORT as it employs a different concept, might recognize epidural space sooner, and favors smaller needles.

Introduction. Atopic dermatitis (AD) is a global problem of the 21st century, as the number of people suffering from this disease is steadily increasing, and around the world, about 20% of the population with clinical manifestations of this disease seek medical help. Aim of the study. Evaluation of the clinical course of AD in children in the hot climate of Uzbekistan. Patients and methods. 215 patients with atopic dermatitis aged from 1 to 18 years were under observation. The severity of AD was determined using the SCORAD index. Results. Among 215 patients, the erythematous-squamous form was observed in 63 (29.3%), erythematous-squamous with lichenification - in 47 (21.8%), lichenoid - in 55 (25.6%), exudative - in 34 (15.8%), and pruriginous form of AD - in 16 (7.4%). Most observed patients were adolescents, and the number of boys and girls with AD in this group was similar (49.6% and 50.4%, respectively). In terms of severity, taking into account the SCORAD index, in infancy, most patients had moderate (47.4%) and mild (36.8%) clinical course; in childhood - moderate (56.1%); in adolescence - moderate (40.3%) and severe (33.8%). In infancy, the exudative form was the most prevalent (52.6%). At the age of 2 to 11 years, the erythematous-squamous and lichenoid forms were the most frequently diagnosed (43.8% and 31.6% of cases, respectively). Meanwhile, at the age of 12 to 18 years, the patients were characterized by a different distribution of forms: the erythematous-squamous form with lichenification was observed in 28.1%, the lichenoid form - in 26.6%, and the erythematous-squamous form in 20.8%. Conclusion. In the present study, we assessed the relative frequency of forms of atopic dermatitis in children of different age groups in the hot climate of Uzbekistan.

Background: Allergic rhinitis is a recurrent inflammation of the nasal mucosa that is triggered by various allergens and has an extremely negative impact on the quality of a patient's life. With the increasing morbidity of seasonal allergic rhinitis worldwide, the possibility of a deterioration in the course of the disease must be taken into account. Consequently, its prompt diagnosis is essential. High levels of total immunoglobulin E, eosinophil cationic protein and eosinophil count, along with appropriate clinical data, are associated with allergic rhinitis. However, studies regarding the relation of allergic reaction predictors with severity of allergic rhinitis symptoms are currently insufficient and inconsistent. The objective of this study was to determine the total immunoglobulin E (IgE), eosinophil cationic protein (ECP) and eosinophil count in blood serum and to identify the relationship of each parameter with the severity of seasonal allergic rhinitis. Methods: This cross-sectional study was conducted in the regional allergological center “DiVera” which is located in Karaganda city (central Kazakhstan). In order to perform statistical analysis, we used initial levels of seasonal allergic rhinitis markers and 4-point scale aspects for assessing symptoms (Daily Symptom Score). Allergic rhinitis markers were identified by using automatic modular and immunological analyzers. The study involved 49 patients aged 18-60 years with a diagnosis of seasonal allergic rhinitis. Verification of the diagnosis was carried out on the basis of a positive allergic anamnesis, objective and subjective patients data. Statistical analysis was performed using the “Statistica” software version 13.0 for Windows. The results were analyzed using descriptive statistics, and Spearman's rank correlation coefficient was applied to determine the relations between the studied parameters. Results: The study revealed a positive direct, strong statistically significant relationship (p<0.05) of all three serological markers - immunoglobulin E (r=0.96), eosinophilic cationic protein (r=0.91), and eosinophil count (r=0.86) with symptom severity of allergic rhinitis. Conclusion: This correlation analysis revealed a relation of eosinophil count, total IgE and eosinophil cationic protein levels to symptom severity in seasonal allergic rhinitis. The concentration of serological markers could be an important predictor of allergic sensitization, particularly in adult patients.

Authors: Sanfriska Ersa , Hastuti Rahmah
Published: August 2022

College student engagement is a sense of student engagement in carrying out their learning in terms of academics (expecting good learning outcomes), emotional (curiosity and a feeling of fun participating in class), cognitive (having good self-regulation skills, wanting challenges in learning), and behavior (full attendance and active involvement in class). As a result of the Covid-19 pandemic, learning systems around the world have been affected until they suddenly change from face-to-face to online learning. This change in the learning system makes students need to adapt again. In this process, college student engagement becomes a challenge that must be faced. The purpose of this research is to provide an overview of college student engagement during the 2 years of online learning. The total participants in this study were 291 students who had filled out a survey containing open-ended questions. The data in this study were analyzed using MAXQDA 2020 to code and categorize responses. The result is that there is a change in academic engagement to be effective in collecting assignments and being flexible, the grades are also good but not accompanied by understanding the material. In behavioral engagement, attendance is more awake but there is no involvement or activity. In cognitive engagement, there is a new strategy in learning, namely recording and adaptation because it is the responsibility of the learner. Lastly, in emotional engagement, students feel bored, lazier and more stressed during online learning because they cannot meet directly with lecturers and friends.

Aim: The aim of this study was to investigate the relationship between internet addiction and metaphorical perception of time with students procrastination during the Corona virus outbreak. Method: The method of this study was descriptive-correlational. The statistical population included all students in Tehran and Mashhad during the outbreak of Corona virus in 2021. To do this, 250 students were voluntarily asked via Instagram to complete Time Perception Metaphorical Questionnaire of Raiisi and Moghadasin (2020), Young Internet Addiction Questionnaire (1996) and Tuckman Procrastination Scale (1991). The statistical method was Pearson correlation and multivariate regression analysis. Data were then analyzed by using SPSS-22. Results: The results indicated that Internet addiction and metaphorical perception of time during Corona virus outbreak are related to the level of students procrastination at this time (P<0.05). Also, internet addiction and metaphorical perception of time can predict 17.8% and 14.6% of procrastination, respectively. Conclusion: To conclude, it can be said that the rate of students procrastination is predictable based on internet addiction and metaphorical understanding of time during the outbreak of the Corona virus. It is suggested that researchers pay more attention to cognitive factors such as metaphorical perception of time and behavioral factors such as internet addiction in their studies on procrastination in this period.

This review article presents the results of a study of Azerbaijan oils for their scientifically based sorting and processing, since they are a valuable raw material for petrochemical processes. Particular attention is paid to the study of light oil products, their qualities are decisive for the assessment of the oil itself. In oils, the qualities of fuel oils, distillate and oil fractions are also determined. Azerbaijan oils, due to their uniqueness, are used as a valuable raw material for petrochemistry. In addition, in connection with the export of oil to world markets, it is important to identify the valuable properties of Azerbaijani oils that allow them to compete with well-known marker oils. Also relevant is the assessment of the qualities of fuel oils and oil fractions of Azerbaijani oils. The review article discusses the quality of oil fractions from offshore fields oils in the Azerbaijan and Turkmen sectors of the Caspian Sea, containing 9-13% paraffin, 14-36% aromatic hydrocarbons. It has been established that base oils with a VI of 80-90 units (I group by API) are obtained by processes of selective purification and dewaxing, as we showed earlier when obtaining oil fractions from promising Azerbaijan oils Azeri, Chirag, etc. To obtain modern high-quality oils with IV 100 and higher, it is possible to use refined oil components from Azerbaijan oils (for example, from Balakhani oil) using and involving hydrocracking oils (20-40%) and a package of additives from foreign companies.

Günümüzde otomasyona dayalı üretim tekniklerinin kullanılmasından dolayı maliyetlerin maliyet yüklenicilerine dağıtımı son derece önemlidir. Geleneksel üretimin işgücü ağırlıklı olması ve toplam maliyet içerisinde genel üretim maliyetlerinin payının az olması durumunda geleneksel maliyet saptama yaklaşımının kullanılması yeterli olabilmekteydi. Ancak günümüzde maliyet yapısı çok değişmiştir. Geleneksel üretimden farklı olarak otomasyona dayalı üretim ortamı, kullanılan işgücünün azalmasına, maliyet yapısının değişmesine yol açmıştır. Üretim maliyetleri içerisinde direkt işçilik maliyetlerinin payı azalırken endirekt üretim maliyetlerinin payı artmaktadır. Dolayısıyla direkt işçilik maliyetlerinin önemi azalmaktadır. Ayrıca değişken maliyetler azalırken sabit maliyetler de artmaktadır. Üretim ortamı ve maliyet yapısının değişmesi, maliyet hesaplama sistemlerini doğrudan etkilemektedir. Bu çalışmanın amacı, bir halı üretim işletmesindeki örnek olay çalışması yoluyla zaman etkenli faaliyet tabanlı maliyet saptama yaklaşımının faaliyet tabanlı maliyet saptama yaklaşımına göre farklılıklarını ortaya koymak ve bu yöntemlerden elde edilmesi beklenen faydaların elde edilebilmesinde karşılaşılan zorluklar ile faaliyetlerin, maliyet yükleyicilerinin ve faaliyet yükleyicilerinin önemini açıklamaktır.

Biaya pakan menjadi kendala tersendiri bagi pembudidaya ikan khususnya di Desa Pedindang Kecamatan Pangkalan Baru Kabupaten Bangka Tengah. Tujuan pengabdian kepada masyarakat untuk membantu pembudidaya mampu memenuhi kebutuhan pakan secara mandiri, melalui pemanfaatan limbah ikan dan sayur. Selain itu, membantu pembudidaya mengatur keuangan usaha agar lebih professional. Metode pengabdian kepada masyarakat adalah aplikasi pembuatan pelet organik (pelor), sekaligus analisis kelayakan usaha pembuatan pakan meliputi analisa laba/rugi, payback period (PP), Return of Investmen (ROI), dan R/C Ratio. Hasil pengabdian, pembudidaya ikan dapat mengaplikasikan teknologi pembuatan pelor sederhana. Hasil analisa kelayakan usaha memberikan dampak signifikan terhadap pendapatan pembudidaya ikan. Jika sebelum ada teknologi keuntungan pembudidaya ikan sebesar Rp 8.069.600,- per 7.000 ekor lele budidaya, maka setelah adanya teknologi, pendapatan pembudidaya meningkat 23% menjadi Rp 9.962.189,5 per 7.000 ekor lele budidaya selama periode pemeliharaan 3 bulan. Aplikasi teknologi ini memiliki periode pengembalian investasi cukup pendek yaitu 0,4 tahun, nilai pengembalian investasi (ROI) sebesar 245,7%, dan R/C ratio sebesar 1,3 atau lebih dari 1 sehingga usaha pembuatan pakan ini layak dikembangkan. Pembudidayajuga mampu mengelola keuangan secara lebih professional

Pakan ikan merupakan permasalahan utama dalam kegiatan usaha bisnis budidaya ikan. Hal ini dikarenakan kebutuhan biaya untuk pembelian pakan ikan menghabiskan 60 – 70% biaya operasional produksi. Kondisi ini berdampak pada menurunnya pendapatan (income) bagi para pembudidaya ikan. Pembudidaya Ikan di Desa Tua Tunu, Kota Pangkalpinang merupakan pembudidaya ikan yang bergerak dalam kegiatan budidaya ikan air tawar. Selama ini kegiatan budidaya ikan yang dilakukan oleh para pembudidaya terkendala oleh besarnya biaya pakan yang dikeluarkan. Bangka Belitung memiliki potensi perairan laut yang menghasilkan ikan-ikan rucah dalam jumlah yang berlimpah. Ikan rucah harganya murah dan bisa digunakan sebagai bahan baku dalam pembuatan pakan ikan. Tujuan kegiatan ini adalah memberikan aplikasi IPTEKS berupa pemanfaatan bahan baku lokal berupa ikan rucah untuk dijadikan bahan baku bagi pembuatan pakan ikan dengan menggunakan teknologi sederhana yang aplikatif. Kegiatan ini dilaksanakan di kolam budidaya ikan yang dimiliki oleh para pembudidaya ikan di Desa Tua Tunu, Kota Pangkalpinang. Hasil dari kegiatan ini yaitu Aplikasi dan desain teknologimampu membantu pembudidaya ikan dalam membuat pakan mandiri. Teknologi yang diterapkan berjalan dengan baik dan membantu mitra pembudidaya ikan dalam mendapatkan keuntungan yang optimal. Biaya produksi untuk pembelian pakan ikan berkurang.

Pendidikan mempengaruhi aspekaspek kehidupan manusia mulai dari segi ahlak, moral, pengetahuan hingga penghidupan seseorang di masa depan. Oleh karena itu pendidikan seharusnya menjadi salah satu prioritas utama dalam pembangunan, karena tingkat pendidikan masyarakat sangat mempengaruhi kualitas sumber daya manusia di suatu negara yang berdaulat. Sebagian diantara masyarakat Indonesia mengalami kemiskinan yang cukup memprihatikan sehingga terjadinya mata rantai pendidikan yang terputus. Oleh karena itu dengan adanya kegiatan IbM (IPTEK bagi Masyarakat), penulis mencoba berinisiatif untuk membuat sebuah wadah pembelajaran yang disebut Rumah Pendidikan dan Revolusi Mental bagi mereka yang kurang beruntung karena tidak memiliki orang tua, putus sekolah karena kekurangan biaya dan sebagai tindakan preventif dalam rangka menurunkan gejala vandalisme dan kriminalisme di Desa Balunijuk, Provinsi Kepulauan Bangka Belitung, Indonesia. Rumah Pendidikan dan Revolusi Mental yang penulis sediakan dibuat dengan beberapa kluster kompetensi yang dimiliki oleh peserta dengan jumlah maksimal 20 peserta dan batas waktu efektif dua bulan. Metode observasi lapangan, wawancara dan survei langsung digunakan untuk mendapatkan gambaran deskriptif kualitatif dankuantitatif serta uji Wilcoxon dengan aplikasi SPSS versi 22 untuk mengetahui nilai kemampuan ilmu komputer sebelum dan sesudah pelatihan para peserta. Program ini diharapkan dapat meningkatkan kualitas sumber daya manusia masyarakat perdesaaan dan memberikan kontribusi terhadap literatur pendidikan dalam bentuk publikasi ilmiah.

Desa Tanah Bawah memiliki potensi lahan dengan ketersediaan sumber air yang melimpah. Selain dapat dimanfaatkan untuk pemenuhan kebutuhan air baku konsumsi, mandi dan cuci, potensi lahan perairan dapat dioptimalkan untuk pengembangan budidaya perikanan. Budidaya polikultur diharapkan dapat memberdayakan masyarakat serta menjadikan Desa Tanah Bawah berpotensi menjadi desa mandiri pangan dari produksi padi sawah dan hasil perkebunan yang melimpah serta perikanan budidaya. Teknologi budidaya polikultur dinilai ramah lingkungan karena didesain untuk meminimalisir limbah buangan sisa pakan yang tidak termanfaatkan. Daya dukung lingkungan perairan bisa tetap dipertahankan. Selain itu secara hitungan ekonomi, pilihan teknologi budidaya polikultur dengan sistem KJA dinilai sangat menguntungkan karena hasil panen yang lebih tinggi dibandingkan dengan sistem monokultur. Hasil panen ikan yang berlipat dari dua komoditas yang dibudidayakan (ikan nila dan ikan mas), otomatis akan mendatangkan keuntungan yang berlipat juga walaupun dengan input biaya produksi yang sama, karena efisiensi dan pemanfaatan pakan yang optimal. Pelaksanaan IbM ini diharapkan dapat meningkatkan ekonomi masyarakat secara signifikan dan dapat berkelanjutan.
