EFFECTIVENESS AND COST-EFFECTIVENESS OF DOUBLE READING IN DIGITAL MAMMOGRAPHY SCREENING: A SYSTEMATIC REVIEW AND META-ANALYSIS
Authors: Tjiayadi Jonathan Billy Christian , Theresia Deborah Josephine 
Published: May 2023

Background: Female breast cancer has become the global leading cause of cancer-related mortality. Although digital mammography has been proposed as an effective and cost-efficient screening method, its real performance and cost-benefit value has been debated by several studies especially concerning the available reading methods. Double reading of digital mammography has been said to increase reading sensitivity but often found some challenges in terms of cost and false positive rate. This systematic review and meta-analysis aim to evaluate the effectiveness and cost-effectiveness of double reading for digital mammography screening.
Methods: This review included comparative studies and cost-effectiveness studies from databases such as Pubmed and Cochrane up to April 2023. We excluded non-English studies, cost-effectiveness studies with lacking adequate statistics, single-armed trials, study protocols, earlier meta-analyses, review articles, and studies that merely evaluated double reading of two different methodologies. Study quality was assessed using the QUADAS-2 tool and CHEERS 2022 checklist. Meta-analysis was conducted to evaluate cancer detection and false positive rate of double reading.
Ten studies were included in this review, three of which were obtained from a reference article. Mammograms in this review were obtained from a total of 260,501 women. Double reading had a slightly but significant chance of finding a breast cancer (OR = 1.137; p-value = 0.004). False-positive rate in double reading was also prominent (ER = 0.041; p value = 0.000). Single reading with CAD was still proven to be a more cost-effective method.
Discussion: Studies in this review was generally had low risk of bias and applicability concern. High cost of double reading may be attributed to the high number of false positive result. Integration of CAD with AI or deep learning may enhance the performance of digital mammography single reading.
Conclusion: with consensus and arbitration, double reading strategy present itself as a screening method for breast cancer, however single reading with CAD has proven more superior as a more-cost effective method.
Maritime Least Cost Path Analysis: Archaic Travel Routes in the Upper Great Lakes
Authors: Peterson Ryan Edward 
Published: May 2023

AbstractThe use of the Cost Path tool in geospatial technologies has allowed for the creation of digital models that can predict past behaviors and movements. While often applied to terrestrial landscapes, these models have gained increasing popularity in modeling movement across maritime and composite landscapes. The methods used in this article, first laid out by Gustas and Supernant, allow for the creation of a model not reliant on known origin and destination points but rather utilize a matrix of points placed arbitrarily around the edge of the study area. This article applies the principles of maritime least cost path analysis to create a predictability model for travel in the upper Great Lakes during the Nipissing high paleolake level event. The result of this paper is a heat density map that can identify (1) high probability travel corridors and (2) coastal areas of high probability travel.

Published: May 2023

Abstract
Here we summarize the current state of knowledge about the precontact archaeology of the Michigan State University (MSU) campus as revealed through work conducted by the MSU Campus Archaeology Program (CAP), the MSU Museum, and the Department of Anthropology. A multipronged approach places this collective work in programmatic, institutional, historical, geographic, and archaeological context. The history of CAP and its impact on campus operations and understandings of campus history demonstrate the strength of such programs. Unpacking the MSU Museum collections reveals additional insight into the deep Indigenous history of university lands. Results of the first systematic excavations of a precontact Archaic site on the MSU campus, the Beaumont West site (20IN205), are reported alongside accounts of systematic archaeological survey conducted over a span of 70 years, recent geomorphological work, and the cumulative collections of precontact material culture from the MSU campus housed at the MSU Museum. Collectively, this paints an engaging multifaceted story of an ever-changing natural and social landscape that highlights the value of understanding the role college campuses can play in providing information about the distant as well as the recent past.

Authors: JASELLI LUCA , PIERONI VITTORIO 
Published: May 2023

An echinoderm fauna from the San Salvatore Formation (Middle Triassic, Southern Alps) is here described in detail for the first time. Identifiable crinoids and echinoids were collected from three different localities: Mt. San Salvatore (Ticino, Switzerland), Rasa di Varese and San Michele (Lombardy, Italy). Crinoid taxa include Encrinus cf. aculeatus, Holocrinus sp. indet., Zardinicrinus cf. granulosus, Encrinidae gen. et sp. indet. Echinoid taxa include “Cidaris” cf. roemeri, Serpianotiaris sp. indet., Triadocidaris transversa, Triadocidaris sp. indet., and an indetermined form (Cidaridae). Most of the material was collected from Rasa di Varese, along with a rich upper Anisian ammonoid and conodont fauna, belonging to the upper Reitzi Zone and the Secedensis Zone. Migration of crinoids have been documented during the upper Anisian (from upper Pelsonian to lower Illyrian), mainly from the westernmost Tethyan Realm northward to the Germanic basin. Crinoid taxa already reported in the lower and upper Illyrian of the Germanic basin have also been collected, dated here to the late Illyrian (upper Reitzi Z.-Secedensis Z.) suggesting that several taxa migrated southwards in the Tethys realm during the late Illyrian.

Published: May 2023

Purpose:
The objective of this study was to investigate the association between trainee level and surgical time and postoperative complications of anterior cruciate ligament reconstruction (ACLR).

Methods:
A retrospective chart review of patients who underwent ACLR at an academic orthopaedic ambulatory surgery center collected demographic and clinical information, including the number of trainees present and trainee level. Unadjusted and adjusted regression analyses assessed the association between trainee number and level with surgical time (time from skin incision to closure) and postoperative complications.

Results:
Of 799 patients in this study operated on by one of five academic sports surgeons, 87% had at least one trainee involved. The average surgical time overall was 93 ± 21 minutes and by trainee level was 99.7 (junior resident), 88.5 (senior residents), 96.6 (fellows), and 95.6 (no trainees). Trainee level was significantly associated with surgical time (P = 0.0008), with increased surgical time in cases involving fellows (0.0011). Fifteen complications (1.9%) were observed within 90 days of surgery. No notable risk factors of postoperative complications were identified.

Conclusion:
Resident trainee level does not have a notable effect on surgical time or postoperative complications for ACLR at an ambulatory surgery center, although cases involving fellows had longer surgical times. Trainee level was not associated with risk of postoperative complications.

Abstract
Dadap River is located in Kosambi, Tanggerang, which often experiences flooding in the estuary. The problem of flooding is caused by the lack of rivers capacity and estuaries caused by sedimentation and tidal conditions. The flooding caused damage to city infrastructure and paralyzed the activities of the affected residents. The Dadap River was normalized in 2012 to overcome the flooding problems. This study aims to determine the capacity of rivers and estuaries as an alternative solution for flood management. Simulations were carried out in conditions before and after normalization and with alternative embankment elevations. Flood modeling using the HEC-RAS 1D unsteady flow. Boundary conditions in the upstream using flood discharge with a 50 and 100 yr return period and downstream using HHWL elevation and wave height. The analysis results show that the capacity of the Dadap River before normalization was not able to accommodate flood discharge at the 50 and 100 yr return period. After normalization, the water surface elevation may decrease by 24-29%. However, there is still flooding downstream due to the tides, so raising the embankment elevation of +3.5 m.

Kali Dadap sering mengalami banjir di bagian muara. Kali Dadap terletak di Kecamatan Kosambi, Kabupaten Tanggerang. Permasalahan banjir di Kali Dadap disebabkan oleh berkurangnya kapasitas sungai dan muara yang disebabkan oleh sedimentasi dan pengaruh oleh kondisi pasang pasang surut. Banjir yang terjadi menyebabkan rusaknya prasarana kota serta melumpuhkan aktivitas warga yang terdampak. Kali Dadap telah dilakukan normalisasi pada tahun 2012 untuk mengatasi permalahan banjir yang terjadi. Tujuan dari studi ini yaitu untuk mengetahui kapasitas kali dan muara Dadap serta sebagai alternatif solusi penanganan banjir. Simulasi pemodelan banjir dilakukan pada kondisi sebelum dan sesudah dinormalisasi serta dengan alternatif peninggian tanggul. Pemodelan banjir dilakukan menggunakan aplikasi HEC-RAS 1D aliran unsteady. Pemodelan akan dilakukan dengan kondisi batas di bagian hulu menggunakan debit banjir dengan kala ulang 50 dan 100 tahun dan di bagian hilir menggunakan elevasi HHWL dan tinggi gelombang. Hasil analisis menunjukkan bahwa kapasitas Kali Dadap sebelum di normalisasi tidak mampu mengalirkan debit banjir kala ulang 50 dan 100 tahun. Setelah dilakukan normalisasi pada Kali Dadap, elevasi muka air dapat menurun sekitar 24 -29% tetapi masih terjadi banjir pada bagian hilir akibat pasang surut sehingga perlu adanya peninggian elevasi tanggul yaitu +3.5 m.

Isolation and Characterization of Extracellular Chitinase Produced by Chitinolytic Bacteria Isolated from Soil Samples
Authors: Gupta Annika Durve , Khanna Shivani Kakkar , Gupta Pooja 
Published: May 2023

Chitin is one of the most common biopolymers found in both marine and terrestrial habitats. Chitinase enzyme has gained popularity due to its diverse biotechnological applications, particularly in agriculture for the biocontrol of phytopathogenic fungi and harmful insects. In this work bacteria producing chitinase enzyme were isolated from soil and water samples. Three bacterial isolates C2, C3, and C4 were found to be Gram-negative coccobacilli while bacterial isolate C9 was found to be Gram-positive cocci. The optimum pH and temperature for all the isolates were studied. The effect of pH, temperature, substrate variation, and incubation period on enzyme activity was studied. The activity of the chitinase enzyme for all the bacterial isolates increased with an increase in temperature up to 37°C. However, a further rise in reaction temperature caused a loss of chitinase activity. Michaelis-Menten plot and Line weaver Burk plot were constructed to calculate the Km and Vmax values. Partial Purification of the chitinase enzyme was carried out and the enzyme activity, protein content, specific activity, and purification fold were estimated. It was observed that the enzyme activity of the crude sample was less than the fractionated sample. The highest enzyme activity was found to be at a 40% fraction. Of the four isolates, C2 was the best in its enzyme activity. The future prospect is the production of chitinases at an industrial scale for various biotechnological applications. Chitinase-producing isolates have the ability to produce chitinase between temperatures 22ºC and 40ºC which is the field temperature for the cultivation of most the crop, so it may be applicable to field conditions against plant pathogenic fungi which is the major problem for agricultural food production. The management of seafood waste businesses may potentially benefit from the usage of this enzyme.

Published: May 2023

Penelitian ini dilakukan berdasarkan latar belakang dari siswa yang lambat ketika belajar dan peserta didik yang lemah dalam mengingat dan lemah dalam memahami pelajaran yang disampaikan oleh pendidik ketika kegiatan pembelajaran Bahasa Indonesia berlangsung, dan juga dikarenakan oleh siswa yang kurang aktif dalam belajar dan tidak menyelesaikan tugasnya dengan baik. Berdasarkan hal-hal diatas, maka dapat diambil rumusan masalah dalam peneltian ini ialah bagaimana gaya atau cara belajar yang digunakan oleh peserta didik ketika melakukan kegiatan pembelajaran Bahasa Indonesia pada kelas 5 SD. Adapun tujuan penelitian ini dilakukan untuk dapat mengetahui cara belajar peserta didik yang berbeda-beda dalam proses pembelajaran Bahasa Indonesia pada kelas 5 Sekolah Dasar. Penulis menggunakan jenis penelitian kualitatif yaitu penelitian lapangan (field research). Serta guru dan siswa kelas 5 akan menjadi subjek dari penelitian ini. Hasil penelitian yang penulis temui dari analisis data wawancara dengan siswa di kelas 5 ialah bahwa mereka lebih dominan menggunakan gaya belajar visual. Yang menjadi penyebabnya dikarenakan ada banyak siswa yang lebih menyukai belajar dengan melihat gurunya menyampaikan materi di depan kelas dan ketika berada di dalam kelas mereka lebih suka membaca yang di dalam buku bacaannya disertai dengan gambar yang berkaitan dengan bacaan ataupun materi dari pembelajaran yang mereka lakukan.
