Network Traffic Measurement Analysis using Machine Learning

Hae-Duck Joshua Jeong(Hae-Duck Joshua Jeong) 한국인공지능학회 2023 인공지능연구 (KJAI) Vol.11 No.2

In recent times, an exponential increase in Internet traffic has been observed as a result of advancing development of the Internet of Things, mobile networks with sensors, and communication functions within various devices. Further, the COVID-19 pandemic has inevitably led to an explosion of social network traffic. Within this context, considerable attention has been drawn to research on network traffic analysis based on machine learning. In this paper, we design and develop a new machine learning framework for network traffic analysis whereby normal and abnormal traffic is distinguished from one another. To achieve this, we combine together well-known machine learning algorithms and network traffic analysis techniques. Using one of the most widely used datasets KDD CUP'99 in the Weka and Apache Spark environments, we compare and investigate results obtained from time series type analysis of various aspects including malicious codes, feature extraction, data formalization, network traffic measurement tool implementation. Experimental analysis showed that while both the logistic regression and the support vector machine algorithm were excellent for performance evaluation, among these, the logistic regression algorithm performs better. The quantitative analysis results of our proposed machine learning framework show that this approach is reliable and practical, and the performance of the proposed system and another paper is compared and analyzed. In addition, we determined that the framework developed in the Apache Spark environment exhibits a much faster processing speed in the Spark environment than in Weka as there are more datasets used to create and classify machine learning models.

According to the Wheelchair Foundation, over 131 million individuals depend on a wheelchair. Wheelchairs drastically improve the quality of life by providing partially disabled persons with mobility. Moreover, wheelchairs have become a central component of many hospitals, necessary to transport patients. However, manual wheelchairs limit users’ or helpers’ freedom by requiring direct actuation, either by turning the wheels or pushing the wheelchair. Electric wheelchairs allow users to navigate a wheelchair through a single control mechanism to improve flexibility. Autonomous wheelchairs are the next step in improving the quality of life and further enhancing user freedom. This paper presents the optimization of an automated wheelchair implementing unique and novel path planning and localization indoors. The results illustrate the implementation of camera vision with LiDAR for obstacle avoidance and advancements in a modular infrastructure.

A review of chronic pectoralis major tears: what options are available?

Joshua R. Giordano,Brandon Klein,Benjamin Hershfeld,Joshua Gruber,Robert Trasolini,Randy M. Cohn 대한견주관절의학회 2023 대한견주관절의학회지 Vol.26 No.3

Rupture of the pectoralis major muscle typically occurs in the young, active male. Acute management of these injuries is recommended; however, what if the patient presents with a chronic tear of the pectoralis major? Physical exams and magnetic resonance imaging can help identify the injury and guide the physician with a plan for management. Nonoperative management is feasible, but is recommended for elderly, low-demand patients whose functional goals are minimal. Repair of chronic tears should be reserved for younger, healthier patients with high functional demands. Although operative management provides better functional outcomes, operative treatment of chronic pectoralis tears can be challenging. Tendon retraction, poor tendinous substance and quality of tissue, muscle atrophy, scar formation, and altered anatomy make direct repairs complicated, often necessitating auto- or allograft use. We review the various graft options and fixation methods that can be used when treating patients with chronic pectoralis major tears.

Retention of Polyphenolic Species in Spray-Dried Blackberry Extract Using Mannitol as a Thermoprotectant

Joshua A. Eldridge,Debra Repko,Russell J. Mumper 한국식품영양과학회 2014 Journal of medicinal food Vol.17 No.10

The purpose of these studies was to determine if a Bu¨chi Mini Spray Dryer B-290 (Bu¨chi Corporation, New Castle, DE, USA) could be used to prepare blackberry extract powders containing mannitol as a thermoprotectant without extensively degrading anthocyanins and polyphenols in the resulting powders. Three blackberry puree extract samples were each prepared by sonication of puree in 30/70% ethanol/water containing 0.003% HCl. Blackberry puree extract sample 1 (S1) contained no mannitol, while blackberry puree extract sample 2 (S2) contained 3.0:1 (w/w) mannitol:berry extract, and blackberry puree extract sample 3 (S3) contained 6.3:1 (w/w) mannitol:berry extract. The levels of anthocyanins and polyphenols in reconstituted spray-dried powders produced from S1–S3 were compared to solutions of S1–S3 that were held at 4 C as controls. All extract samples could be spray-dried using the Bu¨chi Mini Spray Dryer B-290. S1, with no mannitol, showed a 30.8% decrease in anthocyanins and a 24.1% decrease in polyphenols following spray-drying. However, S2 had a reduction in anthocyanins of only 13.8%, while polyphenols were reduced by only 6.1%. S3, with a ratio of mannitol to berry extract of 6.3:1, exhibited a 12.5% decrease in anthocyanins while the decrease in polyphenols after spray-drying was not statistically significant (P = .16). Collectively, these data indicate that a Bu¨chi Mini Spray Dryer B-290 is a suitable platform for producing stable berry extract powders, and that mannitol is a suitable thermoprotectant that facilitates retention of thermosensitive polyphenolic species in berry extracts during spray-drying.

Skeletal Senescence with Aging and Type 2 Diabetes

Joshua Nicholas Farr 대한내분비학회 2023 Endocrinology and metabolism Vol.38 No.3

Osteoporosis and type 2 diabetes (T2D) are common diseases that often coexist. While both of these diseases are associated withpoor bone quality and increased fracture risk, their pathogenesis of increased fracture risk differs and is multifactorial. Mounting evidence now indicates that key fundamental mechanisms that are central to both aging and energy metabolism exist. Importantly, thesemechanisms represent potentially modifiable therapeutic targets for interventions that could prevent or alleviate multiple complications of osteoporosis and T2D, including poor bone quality. One such mechanism that has gained increasing momentum is senescence, which is a cell fate that contributes to multiple chronic diseases. Accumulating evidence has established that numerous boneresident cell types become susceptible to cellular senescence with old age. Recent work also demonstrates that T2D causes the premature accumulation of senescent osteocytes during young adulthood, at least in mice, although it remains to be seen which otherbone-resident cell types become senescent with T2D. Given that therapeutically removing senescent cells can alleviate age-relatedbone loss and T2D-induced metabolic dysfunction, it will be important in future studies to rigorously test whether interventions thateliminate senescent cells can also alleviate skeletal dysfunction in context of T2D, as it does with aging.

Background: Patellofemoral tendinopathy is a common condition that is associated with anteromedial knee pain due to chronicrepetitive tendon overloading. Physical therapy in combination with an eccentric exercise program has been thought to be the goldstandard of treatment for patellofemoral tendinopathy. The aim of this study was to examine the literature regarding theeffectiveness of treating patellofemoral tendinopathy with eccentric exercise and other interventions. Methods: A literature search of Medline Complete, PubMed, CINAHL Complete, and Journal of Science and Medicine in Sports was conducted using PEDro guidelines. Results: Eight articles met our selection criteria. The 8 articles investigated individuals who all had pain at the inferior pole of thepatella or were diagnosed via ultrasound for patellar tendinopathy. The articles investigated the effects of eccentric exercise versus other treatments such as, progressive tendon-loading exercise therapy (PTLE), extracorporeal shock wave therapy (ESWT),percutaneous electrolysis (PNE), dry needling (DN), and concentric hip muscle strengthening. Ultimately, each treatment resultedin decreased pain and patellar stiffness, along with improvement in outcome measures, but it was found that no intervention was more effective than eccentric exercise alone, besides progressive tendon-loading exercise therapy. Conclusions: Moderate to strong mixed evidence exists to show the effect of eccentric exercise in combination with otherinterventions decreases patellofemoral pain and increased functional mobility in individuals with patellofemoral tendinopathy. Progressive tendon-loading exercise therapy was the one treatment that showed more significant improvements in outcome

A Farce that Wounds Both High and Low: the Guan Yu Cult in Chosŏn-Ming Relations

Joshua Van Lieu 서강대학교 종교연구소 2014 Journal of Korean Religions Vol.5 No.2

Scholarship on Chosŏn gratitude to the Ming in the wake of the Imjin Wars stresses Chosŏnloyalism and nostalgia for a lost civilizational order then only remnant as a final human outposton the Korean peninsula standing firm before the tides of northern savagery. There wasa very different undercurrent, however, in which the Chosŏn officialdom of the capital sawthe Ming as irrational and even culturally alien, if not barbarous, violators of propriety. This paper examines these tensions and contradictions through the construction of Chosŏnstate temples to Guan Yu, known in his deified form as Kwan Wang, at the close of thesixteenth century and the roles the cult and its temples played as a discursive space in whichthe Ming and Chosŏn governments negotiated the nature and dynamics of their relationship.
