Integrate Ergonomics into Production System Design
Authors: Neumann Patrick , Kihlberg S. , Medbo P. , Winkel Jorgen 
Published: September 2022

<p> A case study is presented evaluating the productivity and ergonomic consequences ofstrategies implemented in a re-design of an electronics assembly system. The companyapplied partial automation strategies for assembly and transportation functions, movingfrom a parallel-batch to a serial line-based production system. Through simultaneousconsideration of technical and ergonomic indicators we aimed to identify linkagesbetween design decisions, productivity, and ergonomics. Data obtained from companyrecords and key company informants were combined with detailed video analysis,biomechanical modelling and field observations of the system. Implementation of thestrategy to partly automate assembly operations was seen to reduce labour inputs forcomponent assembly work without directly affecting ergonomic conditions. The automation of transportation strategy reduced both labour inputs and work in progress.This strategy also resulted in considerable reductions in work-task variability, and henceincreases in repetitiveness for operators at manual assembly workstations. The manualassembly station examined had some increase in shoulder load amplitudes and a largerincrease in the time-density of work (reduced porosity). Work activities were focusedalmost exclusively on stereotyped ‘get and put’ actions which increased in averagefrequency from one every 8.3 seconds to one every 7.4 seconds. Workstation design wasconstrained by initial decisions to adopt automation technologies and also affected bylater problems in the automation of assembly. Ergonomic conditions varied acrossindividuals and stations in the system. The adopted work organisation plan resulted inuneven distribution of risk factors across operators in the production system. It isconcluded that strategic decisions made early in the design of the production system haveconsiderable impact on ergonomic conditions in the production system. Optimal designfor sustainable and efficient production require simultaneous and integrated considerationof technological and operator functions in the manufacturing system. </p>
Technical Object, Baby Mimesis, and Affective Scaffolding

Published: September 2022

Posthumanism perspectives see the relationship between humans and technology in inter-connected ways exploring cognition, perception, and awareness co-developmental implications with technology. This article focuses on the interplay between technical objects and the baby niche of development. Two main concepts will guide the discussion: posthuman mimesis and the affective dimension as a possible regulative mediator for object-subject relationships. The broad research question is: How do babies deal with increasingly complex technology daily? Which regulative role does mimesis and affective scaffolding play in regulating babies—technical objects relationship? Considering the two main concepts of baby mimesis and affective scaffolding, I discuss two examples of two babies (one boy and one girl of about 1 year old) via a naturalistic observation of babies interacting with the smartphone. The baby’s niche becomes a mimetic and affective space where the interaction is enacted. The article questions the relationship with the technological in a subject and object dialectic in a time of digital, social, technological, and economic significative transformation.

Turkiye’s Africa-Sub-Saharan Policies and Its Competition with France
Authors: TEKİR Osman 
Published: September 2022

Turkiye increased its presence in Central Asia, Caucasus, Balkans, and especially Africa by transforming its foreign policy. Undoubtedly, this situation requires a new perception in foreign policy. Therefore, it required the causes of the policy of disinterestedness to these regions in the 20th century.
Turkiye, endeavored to structure its African policy with the soft power instruments emanated from its historical background by stressing cultural and religious values. Being aware of the fact that soft power is not sufficient enough, hard power instruments have also been implemented after Arab Spring in 2011. Certainly, Türkiye’s foreign policy in Africa disturbs imperialist powers especially France which wants to maintain its influence.
This study deals with Türkiye’s historical presence in Africa, its soft and hard power instruments and its relations with France which has interests in the region.

The evolution of therapeutic technologies dictates the development of a strategy for their implementation in clinical practice. The first stage is the assessment of the capabilities, efficiency, advantages and disadvantages, development of indications and contraindications on models of eye diseases in the experiment.The purpose of the work: to develop criteria for assessing the effectiveness of anti‑angiogenic drugs and evaluate the proposed modeland neovascularization of the eye in the experiment.Materials and methods. Neoangiogenesis models – two chorioretinal and two corneal localizations – were formed in the experiment on rabbits of Sovetskaya Chinchilla breed. The advantages and disadvantages of each of them were analyzed empirically. Experimental animals with neovascular disease were treated with recombinant peptides with angiostatic potential (tumstatin, PEDF, endostatin). In the course of treatment, we developed efficacy criteria based on clinical, instrumental, and morphological studies.Results. Comprehensive efficacy evaluation criteria were developed and tested, allowing not only to reveal and describe the spectrum of biological effects of the tested drugs, but also to quantitatively assess and compare their therapeutic potential with each other at almost all stages of vascular assembly. The complex consisted of qualitative and quantitative clinical (hyperemia, edema, vascularization, antiangiogenic activity according to a score scale), angiographic (intensity and area of edema, area of neovascularization and index of corneal vascularization) and morphological (extent of edema, extent of vessels and their number in section, index of vascularization) indicators.Conclusion. To get the full amount of information about the tested drug with the claimed angiostatic potential, it is necessary to use several models of neoangiogenesis with different mechanisms to study the amplitude and spectrum of their effects.

Published: September 2022

A template-free and one-step carbonization process was developed for fabricating graphitic porous carbon spheres (GPCSs) on hemicelluloses as the electrode material for supercapacitors. This method is green, low-energy, and less time consuming compared to the conventional two-step process (pore-forming and graphitizing). It uses K2FeO4, a mild activating agent that fulfills synchronous activation and graphitization. The GPCSs is regular spherical shape, have high nanoporosity, a large specific surface area (1,250 m2 g−1), and have a high graphitization degree. A unique structural advantage includes a rich interconnected conductive network for electron transfer that shortens the ion transport distance of the electrolyte. Remarkably, the GPCSs electrode displays outstanding electrochemical performance including high specific capacitance (262 F g−1 at 1.0 A g−1), rate capability energy (80%, 20 A g−1), and excellent cycling stability (95%, 10,000 cycles). This work represents a powerful methodology to develop sustainable and low-cost energy storage devices from hemicellulose.
Exploring the relationship between bearing extrusion and postoperative persistent pain in Oxford unicompartmental knee arthroplasty: A trajectory measurement study
Authors: Wen Pengfei , Zhang Qidong , Sun Xiaowei , Zhang Binfei , Ma Tao , Zhang Yumin 
Published: September 2022

Objective: The aim of the study is to explore the relationship between the extrusion of the meniscus bearing and postoperative persistent pain of Oxford unicompartmental knee arthroplasty.Methods: Patients undertaking Oxford UKA from January 2019 to June 2020 were retrospectively analyzed. Intraoperatively, the displacement and movement trajectory of the meniscus bearing was recorded by the specially designed gridding mold of the tibial component. The k-means clustering analysis was applied based on the incidence of postoperative persistent knee pain and the bearing extrusion distance. The intraoperative meniscus bearing movement trajectories were analyzed between the two groups and the patients’ clinical outcomes and radiographic assessments.Results: The k-means clustering analysis indicated that the extrusion of the bearing of 5 mm was the grouping standard. There were 27 patients with 30 knees in the extrusion group and 58 patients with 68 knees in the non-extrusion group. The proportion of optimal bearing movement trajectories in the extrusion group was significantly lower than that in the non-extrusion group (p &lt; 0.05). Postoperative persistent knee pain occurred in six cases (6.1%), with four and two cases in the extrusion and non-extrusion groups, respectively. The incidence of postoperative persistent knee pain in the extrusion group was higher than that of the non-extrusion group (p &lt; 0.05). Radiographic assessment showed that the continuity of the femoral and tibial components in the extrusion group was greater than that in the non-extrusion group (p &lt; 0.05). However, there were no differences in pre- and postoperative HKAA, the varus/valgus degree of both femoral and tibial components, and the flexion/extension angles of the femoral component, and the tibial slope also showed no statistical difference (p &gt; 0.05).Conclusion: For Oxford mobile-bearing UKA, the extrusion of meniscus bearing over 5 mm may increase the incidence of postoperative persistent knee pain, while the improvement of the bearing movement trajectory can effectively reduce this complication.
