Efisiensi pada Mesin Shuttle 75” SGA Tipe 1515 melalui Perbaikan Teropong Tidak Oper
Authors: Amar Amar , Rumiyati Valentina Sri Pertiwi , Oktaviani Bintan , Astutik Rina Aprilia Puji 
Published: August 2023

Penyebab dominan dari mesin tenun yang sering berhenti antara lain terjadinya kerusakan mesin, salah satu kerusakan pada bagian change berupa teropong yang tidak oper. Penelitian ini menggunakan metode observasi, dokumentasi dan wawancara. Hasil analisis ditemukan tiga faktor yang mempengaruhi teropong tidak oper yaitu, faktor manusia, faktor mesin, dan faktor metode. Faktor manusia disebabkan oleh mekanik kurang teliti dalam melakukan perbaikan yang menyebabkan mesin mengalami kerusakan berulang. Faktor mesin disebabkan oleh jarak cross spindle dengan cross spindle hook yang tidak sesuai akibat adanya getaran mesin. Faktor metode disebabkan oleh penyetelan weft feeler yang kurang tepat sehingga mengakibatkan feeler tidak bisa mendeteksi benang. Cara mengatasi faktor yang menyebabkan teropong tidak oper adalah melakukan penyetelan ulang terhadap weft feeler dengan jarak antara feeler dan palet 1,5 mm, melakukan penyetelan ulang terhadap cross spindle dengan cross spindle hook dengan jarak 0,8 mm, serta melakukan pengarahan terhadap mekanik supaya lebih meningkatkan ketelitian ketika melakukan perbaikan atau pengecekan mesin. Hasil pengamatan di lapangan menunjukkan bahwa jumlah teropong yang tidak oper pada salah satu mesin shuttle sebanyak 29 kali selama 7 jam dan rata-rata efisiensi selama tiga shift atau sebesar 65%. Setelah dilakukan penanganan dan perbaikan, jumlah teropong yang tidak oper mengalami penurunan sebesar 79,31 % dengan jumlah 6 kali selama 7 jam, sedangkan efisiensi mesin mengalami kenaikan sebesar 13,33% dengan rata-rata efisiensi selama tiga shift yaitu 75%.
Dialética em busca de hipóteses
Authors: Barahona Constança 
Published: August 2023

Dialética é a ferramenta do filósofo e auxilia-o na investigação do que é comum ao conhecimento geral. O debate acerca dos princípios pressupõe a idéia de que não há conhecimento strictu sensu do próprio funcionamento da adesão da base da ciência. Segundo esse modelo, a dialética, portanto, estaria fora do conhecimento cientifico, mesmo que isso seja discutível dentro da própria obra do Estagirita.
Notas para reflexão sobre o feminino com a Ética de Espinoza
Authors: Magalhães Alcina das Graças Ramos de 
Published: August 2023

Observa-se que na tradição filosófica ocidental -- Platão e todos os pensadores por ele influenciados --, o homem é pensado em termos do dualismo mente-corpo, em que a mente tem mais valor do que o corpo. Este artigo se propõe a refletir como a filosofia de Spinoza, em sua obra magna, a Ética, pode contribuir para avalorização do corpo e assim construir um novo conceito de “feminino”.
Considerações sobre a Genealogia de Nietzsche: má consciência e ideal ascético
Authors: Melo Igor Alves de 
Published: August 2023

Meu objetivo neste artigo é analisar a significação psicológica da má consciência na história da gênese do ideal ascético tomando a Genealogia como obra capital. Segundo minha hipótese, a má consciência se manifesta por meio de crises sucessivas, precisamente quando o corpo social atinge um limite no qual não consegue suportar a interiorização dos instintos agressivos, ao mesmo tempo em que o ideal ascético busca dar conta da crise com novos meios de consolo, sempre disfarçado sob novas roupagens e artifícios.
Sobre a Democracia Deliberativa: Joshua Cohen a Jürgen Habermas
Authors: Amorim Wellington Lima 
Published: August 2023

Esse artigo tem por objetivo fazer um balanço crítico sobre a teoria de democracia deliberativa de Jürgen Habermas a partir da teoria de democracia deliberativa de Joshua Cohen. Esse autor tem a vantagem de aproveitar criticamente as contribuições da idéia de democracia de Habermas, ampliando a sua teoria, Cohen critica Habermas porque este se limita a mostrar que os atores da sociedade civil podem “influenciar” em momentos de crise o sistema político. Para Cohen, ao contrário, é preciso pensar em formas de participação direta da sociedade civil nas tomadas de decisões políticas. Portanto, trata-se de participação e não de mera influência. Sendo assim, apresentaremos as limitações da teoria habermasiana superadas por Cohen.

Um método de fuga da contradição no Fédon de Platão
Authors: Delgado Gabriel Ribeiro 
Published: August 2023

Na última prova da imortalidade da alma do Fédon vemos a aplicação de um método raro nos diálogos platônicos, a saber, um método que cria a necessidade de um juízo através da procura de um objeto que impossibilite o contrário desse juízo. Esse método alcança verdades impressionantes, e iremos expô-lo como possível chave interpretativa para solucionar algumas questões platônicas importantes. Referências bibliográficas PLATÃO.

A compreensão da existência como condição pré-significativa diante da significação analítica da existência a partir da crítica de Søren Aabye Kierkegaard
Authors: Reis Pereira Claudinei 
Published: August 2023

Este trabalho aborda a categoria da existência em Søren Kierkegaard.Objetiva-se apresentar um contraponto entre a análise crítico-reflexiva kierkegaardiana e a compreensão especulativo-abstrata da existência, ou seja, sob uma ótica objetivante, analítico-lógico-linguística da existência. Explica-se como o indivíduo fora reduzido à especulação, a teorias, a sistemas linguísticos que, no fundo, nada dizem a respeito da existência. Por outro lado, detemo-nos na reflexão kierkegaardiana do valor do sujeito existente, pensado a partir do olhar sobre a condição, necessariamente, pré-significativa, pré-sistemática do indivíduo.

O princípio de individuação em Schelling e as influências na construção da categoria da subjetividade em Kierkegaard
Authors: Miranda de Almeida Jorge 
Published: August 2023

O principal objetivo desse artigo consiste em evidenciar como Kierkegaard dialoga com Schelling em torno da categoria da individuação e de que maneira o pensador alemão influencia o filósofo dinamarquês na construção da categoria pelo qual tem a maior estima e considera a sua maior contribuição para com a Filosofia. O deslocamento realizado por Kierkegaard quanto a ruptura da compreensão de Schelling do indivíduo e como se realiza a individuação de Deus e a singularização do homem enquanto liberdade enredada é uma influência direta e que encontra-se em Kierkegaard especialmente em obras como O conceito de Angústia e em As Obras do Amor. Dessa forma, ao artigo problematiza nos dois autores a intrínseca relação entre a liberdade, a existência, o existente e a recusa de inclui-los em qualquer tipo de sistema, pois liberdade e sistema são incompatíveis, onde há sistema, há fatalismo ou determinismo; ou se não há determinismo é uma existência de conceitos, uma existência lógica, logo, uma não existência real e efetiva.Referências bibliográficas ARENDT, Hannah.

Ultrasound-Guided Tenotomy Via a Hydrosurgery Resection Device Improves Symptoms of Chronic Elbow Tendinopathy: A Multi-Center Prospective Study
Authors: Strauser-Curtis Kaylin , Varacallo Christopher P. , Voss Tyler T. , Stephens Chad B. , Kapteyn Reginald W. 
Published: August 2023

Objectives To test the hypothesis that ultrasound-guided, minimally invasive tenotomy using the TenJet™ resection device might provide symptomatic pain relief and functional recovery to patients with chronic tennis or golfer’s elbow. Methods This multi-center, prospective, single-arm study enrolled patients who experienced pain symptoms persisting >3 months, failed conservative care, demonstrated ultrasound or magnetic resonance imaging findings consistent with the diagnosis of tendinosis, and had opted for ultrasound-guided treatment using the TenJet resection device. Post-procedure follow-ups occurred at 2 and 6 weeks and 3, 6, and 12 months. Outcome measures included a patient-rated elbow evaluation (PREE) questionnaire for pain and function, visual analog scale (VAS) for pain, procedure complications, and adverse events. Results A total of 29 patients (32 elbows) were enrolled in the study. Significant improvements in mean PREE total scores and mean VAS scores were observed at all follow-up time points (both p < 0.05). There were no device malfunctions or procedure-related complications. Two patients (6.9%) proceeded to have open debridement, one after the 2-week follow-up visit and the other after the 3-month follow-up visit. Conclusion Ultrasound-guided tenotomy and debridement using the TenJet resection device provided patients with significant pain relief and functional recovery. Additional studies may be necessary to further validate the clinical outcomes observed in this study.
Surgical Device Representatives Preference for Experiential Learning via Immersive Virtual Reality
Authors: Pickham David , Lohre Ryan , Goel Danny 
Published: August 2023

Background Surgical device representatives (SDRs) traditionally receive product training through didactic and hands-on learning. Immersive virtual reality (IVR) training effectiveness and user perceptions has not been studied in this population. The purpose of this study was to evaluate the learning efficiency of IVR for SDRs using a revision total knee arthroplasty system, determine SDR views on the use of IVR for training, and to perform a cost analysis of IVR training compared to traditional means. Methods A cross-sectional study of SDRs attending an anual sales meeting of a single orthopaedic implant company completed a revision total knee arthroplasty module using the Precision OS IVR System after a 1-hour traditional didactic lecture and small-group discussion training format. Immersive VR performance was tracked by the Precision OS software including repetitions, completion times, and performance measured using a previously validated performance metric, the Precision Score. An eight question survey was collected after IVR module completion. Results Two-hundred eighty-six SDRs completed over 1048 module repetitions for an average of approximately 4 module completions per SDR. The cumulative IVR training time was 18.3 minutes (SD 8.5). There was a high rate of critical injuries (n=458, 74%) measured including the medial and lateral collateral ligaments, popliteal artery, and amount of bony resection. The Precision Score had strong, inverse correlation to these injuries and were tracked over module repetitions. Two-hundred forty-five SDRs completed the post-training survery for a response rate of 86%. Most participants (91%) preferred IVR to standard training formats. Almost all participants (99%) intended to use their IVR learning in their current roles, and 99% felt the use of IVR was relevant to their roles. Similarly, 99% would recommend IVR training to others. The cumulative direct costs of IVR training compared to traditional didactic, in-person training formats for SDRs was 2.8x less costly, a lower bound as this did not account for lost productivity. Conclusion Immersive VR training is able to assess and track SDR learner performance and is valued by SDRs greater than traditional training formats. The cost of incorporating this technology is 2.8x less than current didactic and in-person learning formats. This is the first study of its kind to assess the use of IVR in the SDR population.
3D Bioprinted GelMA-Gelatin-Hydroxyapatite Osteoblast Laden Composite Hydrogels for Bone Tissue Engineering.

Published: August 2023

Introduction 3D bioprinting offers a novel solution to critical sized bone defects by allowing the placement of osteogenic cells, additive biomaterials and bioactive signaling that mimic native tissue. We describe the suitability of an extrusion-based 3D bioink composed of gelatin methacryloyl (GelMA), gelatin, hydroxyapatite (HA), and osteoblasts for bone tissue engineering. Methods A mouse calvarial osteoblast-laden GelMA-gelatin-LAP bioink consisting of various concentrations of HA was 3D-bioprinted into a porous hydrogel construct. After days 1, 14, and 28, five constructs from each HA concentration were analyzed. The water weight percent differences of the hydrogels and the degradation behavior in enzyme solution were characterized. An ALP assay and histological analysis were performed. Cell survivability was determined using a LIVE/DEAD Viability/Cytoxicity Kit and AlamarBlue Cell Viability reagent. Real-time polymerase chain reaction (RT-qPCR) was performed to measure expression levels of bone morphogenetic protein-7 (BMP-7) and Osteocalcin (BGLAP). Results The addition of 5, 10, and 20 mg/ml of HA significantly reduced hydrogel swelling (p ≤ 0.01) from baseline GelMA-Gelatin hydrogels (Figure 3A). HA significantly decreased hydrogel breakdown in a concentration dependent manner (Figure 3B, p ≤ 0.001). A significant increase in cell proliferation at day 28 was noted in all groups (Figure 3D). ALP activity (Figure 3E) significantly increased with the addition of 5mg/ml and 20mg/ml of HA at days 7 and 28 (p ≤ 0.05). Live/dead staining at 1, 14, and 28 days showed high chondrocyte viability. The addition of 20mg/ml of HA demonstrated significantly greater BMP7 and BGLAP gene expression at both 14 and 28 days over the hydrogels without HA (Figure 5, p ≤ 0.05). Conclusion The addition of HA to GelMA-gelatin hydrogels significantly decreased hydrogel swelling, improved the ability of the hydrogel to resist enzymatic degradation, increased osteoblastic differentiation and mineralization, and increased osteogenic gene expression while maintaining equal cell viability and proliferation to non-HA hydrogels.
Supine Elbow Arthroscopy: A decade of results with a vertical humerus and a free forearm
Authors: Hunter A. Lee 
Published: August 2023

Background Elbow arthroscopy has been in existence for decades, but to date little innovation in elbow positioning for arthroscopy has occurred. After experiencing disadvantages with lateral decubitus, prone, and supine suspended positioning techniques, the author has changed to a supine positioning technique that stabilizes the humerus vertically while leaving the forearm free for all elbow arthroscopy procedures. Methods A retrospective review was conducted for arthroscopic elbow surgeries performed by a single surgeon in a single surgery center in the supine elbow arthroscopy (SEA) position from 2011 to 2021. Efficiency, safety, and versatility of elbow arthroscopy performed in the SEA position were analyzed. Results In 298 relevant arthroscopic surgical procedures performed on 289 patients, the average total procedural time was 52.2 minutes, with an average arthroscopic (surgical) time of 31.2 minutes. No complications were found in the review of medical records. Conclusions SEA promotes safe, technically easier, and more efficient elbow arthroscopy with improved surgical access, intraoperative flexibility, and accelerated procedural times compared with other current techniques.
The Demographic Make-up of Orthopaedic Surgery Residents in the United States Post ACGME Merger
Authors: Ranson Rachel , Mao Herbert , Saker Christopher , Lehane Kevin , Gianakos Arianna , Stamm Michaela , Mulcahey Mary K 
Published: August 2023

Objective The purpose of this study was to investigate differences in the demographic characteristics of orthopaedic surgery residents in 2021 in regard to sex, degree earned, and regional or medical school affiliation. Design The Fellowship and Residency Electronic Interactive Database was used to identify all orthopaedic surgery residency programs in the United States. Resident sex, degree, residency year, and geographic region attended for residency and medical school were collected from each program website. Results 199 orthopaedic surgery residencies were identified: 153 traditional Accreditation Council for Graduate Medical Education (tACGME) programs, 38 traditional American Osteopathic Association (tAOA) programs, and 8 military programs, which were excluded. 4,095 orthopaedic surgery residents were identified. Females accounted for 16.6% (N=679) of residents, 17.6% (N=620) within tACGME programs and 10.4% (N=59) in tAOA programs (p<0.001). The 573 orthopaedic residents with DO degrees accounted for 14% of the residents identified, 97.6% (N=533) of residents in tAOA programs, and 1.1% (N=40) of residents in tACGME programs. Regional data showed that 34.4% (N=1208) of MDs trained in the Northeast, while 41.9% (N=240) of DOs trained in the Midwest. Conclusion There has been a slight increase in the representation of females and DOs in orthopaedic surgery residency programs since the mid-2000s; however, data following the ACGME and AOA merger still shows significant predilection for male and MD degree applicants. This study suggests that the Northeast and Midwest regions of the United States train more MDs and DOs, respectively. This finding offers potential data for interested applicants and demonstrates opportunity for more heterogeneity in applicant selection.
Number of Stairs at Home is Associated with Discharge to Post-Acute Care Facility Following Total Knee Arthroplasty
Authors: Williams Jaques , Held Michael B. , El Othmani Mouhanad , Neuwirth Alexander L. , Geller Jeffrey A. , Cooper H John , Shah Roshan P. 
Published: August 2023

Background Discharge to post-acute care facility (PACF) carries significant cost and quality burdens to patients undergoing total knee arthroplasty (TKA). In a recent study of pre-bundled payment model patients, the number of stairs (NOS) at home did not influence discharge to PACF for total hip arthroplasty. However, no study has yet examined NOS as it relates to discharge destination after TKA. In a large metropolitan market, it is not uncommon to have several flights of stairs leading to a home. We hypothesize that the number of unavoidable stairs to enter a home is a significant risk factor for discharge to PACF. Methods We reviewed 557 patients who underwent elective TKA at a single urban academic medical center between November 2011 and October 2014. Demographic data as well as NOS, ASA score, RAPT score, LOS, operative time, and tranexamic acid use were collected. T-tests, ANOVA, and Kruskal-Wallis analysis were conducted followed by a logistic regression to compare associations of factors to discharge to PACF. Results Of the 540 patients included in analysis, 193 (35.7%) were discharged home and 347 (64.3%) were discharged to a PACF. NOS (OR=1.457, p<0.001) and increased age (OR=1.057, p<0.001) were found to be significant risk factors for discharge to PACF while female sex (OR=0.57, p=0.013) and higher RAPT scores (OR=0.83, p=0.004) were protective against discharge to PACF. Conclusion With the conclusion of recent bundled payment programs, financial carrots may disappear, though it is likely that sticks will remain. Therefore, all risk factors must be identified and addressed. We found, in a pre-bundled payments era, that stairs is a risk factor for non-home discharge in a metropolitan population, and we confirmed other known risk factors of older age, higher ASA score, and lower RAPT score.
