目的研究Aerospace Medicine and Human Performance更名前后的主要报道方向、国别、发文机构的变化情况等,以期为国内同行提供参考。方法主要利用CiteSpace的共词网络功能来对期刊报道方向、发刊国别、发文机构等变化进行分析。数据来自Web of Science核心合集的SCI拓展版,以期刊名“Aviation Space and Environmental Medicine”检索,时间跨度为1991年1月1日至2014年12月31日,剔除征稿启事、会议通知等非学术文献。导入NoteExpress软件进行去重,共有4830篇文章。该刊于2015年更名为“Aerospace Medicine and Human Performance”,检索策略为:时间跨度为2015年1月1日至2023年6月13日,数据清洗方法同上,共检索到1076篇文章。结果(1)主要发文机构:更名前主要供稿机构为美国空军(160篇)、美国国防部(93篇)和美国宇航局(NASA,77篇);更名后主要供稿机构未发生变化,但发文数量均较更名前减少,美国空军47篇,美国国防部24篇,NASA 24篇。(2)主要关键词对比:更名后主要关键词与飞行、航天相关的连接强度显著增加,而对一般健康问题的关注相对减少,出现了spaceflight、air travel等直接与飞行行为相关的内容。(3)主要国别:更名前美国发文2411篇(49.91%)、加拿大发文314篇(6.50%)、英国发文279篇(5.77%)、法国发文167篇(3.45%)、德国发文160篇(3.31%);更名后美国发文501篇(46.56%)、英国发文98篇(9.10%)、中国发文54篇(5.01%)、加拿大发文53篇(4.92%)、法国发文42篇(3.90%)。(4)年均发文量:根据检索结果,更名前共24年,年均发文201篇;更名后从2015年至本文检索截止时间共8.5年,年均发文127篇,年均报道量下降较多。(5)影响因子:截止2014年更名前共发文164篇,影响因子1.0051(含自引);2016年是该刊更名有影响因子等统计数据的第一年,共发文132篇,影响因子0.8250;2022年发文109篇,影响因子1.0001(含自引)。综合考量发文量和影响因子,该刊的综合影响力更名后并无显著提升。结论该刊在更名后,对于飞行环境的影响报道有所减少,主要讨论范围从之前的所有飞行类型聚焦为以太空飞行为主,关于飞行行为对人体健康的影响和绩效表现的报道大幅增长,同时也增加了关于飞行装备对飞行安全影响的讨论。随着航空航天技术的进步和航空装备的发展,更深入地探讨航空活动中环境因素对人体长时间复合作用的影响是必然。在该刊更名后,我国的发文数量排名第三,也在一定程度上说明存在高质量原创性成果外流的情况。我国期刊在坚持刊物原有特色的前提下,根据领域研究的发展,与时俱进,探索可持续发展的办刊模式;要进一步明确期刊定位与服务对象,以国家重大需求为导向,聚焦航空航天领域前沿、热点,适时调整栏目设置,提升期刊的学术质量和学科影响力,打造高质量的学术交流平台。

VR and AR in human performance research―An NUS experience

With the mindset of constant improvement in efficiency and safety in the workspace and training in Singapore,there is a need to explore varying technologies and their capabilities to fulfil this need.The ability of Virtual Reality(VR)and Augmented Reality(AR)to create an immersive experience of tying the virtual and physical environments coupled with information filtering capabilities brings a possibility of introducing this technology into the training process and workspace.This paper surveys current research trends,findings and limitation of VR and AR in its effect on human performance,specifically in Singapore,and our experience in the National University of Singapore(NUS).

Bayesian estimator of human error probability based on human performance data

A Bayesian method for estimating human error probability（HEP） is presented.The main idea of the method is incorporating human performance data into the HEP estimation process.By integrating human performance data and prior information about human performance together,a more accurate and specific HEP estimation can be achieved.For the time-unrelated task without rigorous time restriction,the HEP estimated by the common-used human reliability analysis（HRA） methods or expert judgments is collected as the source of prior information.And for the time-related task with rigorous time restriction,the human error is expressed as non-response making.Therefore,HEP is the time curve of non-response probability（NRP）.The prior information is collected from system safety and reliability specifications or by expert judgments.The（joint） posterior distribution of HEP or NRP-related parameter（s） is constructed after prior information has been collected.Based on the posterior distribution,the point or interval estimation of HEP/NRP is obtained.Two illustrative examples are introduced to demonstrate the practicality of the aforementioned approach.

Intelligent Subtle Forces and Fields Decide Human Performance:Jain Perspective–I

In this article,emphasis is laid on the manifesting powers of the soul.The powers of the soul manifest as working intelligent force called here as faculties.Eight faculties are defined corresponding to eight types of karma.A schematic model of human system based on Jain principles and scientific findings is presented.The role of DNA and its inadequacies as physical force is discussed.It is stated that genes are only coding devices and the biological intelligence of the soul provides the information for design and structure of the body.The role of biophotons in regulating the biochemistry and biology of life is discussed.Scientific evidence suggests that biophotons originate from the coherent field in DNA.It is argued that the karman body exists as coherent field and the karmanvarganas shedding off the karman body form the biophotons.These biophotons have the information for the reactions to take place in cells.In this model,biophoton provides a link between the karman body and the gross physical body.

Human Performance in Critical Scenarios as a Benchmark for Highly Automated Vehicles

Before highly automated vehicles(HAVs)become part of everyday traffic,their safety has to be proven.The use of human performance as a benchmark represents a promising approach,but appropriate methods to quantify and compare human and HAV performance are rare.By adapting the method of constant stimuli,a scenario-based approach to quantify the limit of(human)performance is developed.The method is applied to a driving simulator study,in which participants are repeatedly confronted with a cut-in manoeuvre on a highway.By systematically manipulating the criticality of the manoeuvre in terms of time to collision,humans’collision avoidance performance is measured.The limit of human performance is then identified by means of logistic regression.The calculated regression curve and its inflection point can be used for direct comparison of human and HAV performance.Accordingly,the presented approach represents one means by which HAVs’safety performance could be proven.

Ontology-Based Approach for Human Competency Gap Analysis in Air Traffic Management:A Case Study of Georgia

The Global Air Navigation Plan is a flexible global engineering approach that allows all States to advance their Air Navigation capacities based on their specific operational requirements.Aviation professionals have an essential role in the transition to,and successful implementation of the GANP.The research work is focused on the creation of methodology for the partial automation of the comparison competences of Air Traffic Management(ATM)personal and synthesis of training courses and modules,using a formal,ontology-based approach as a tool to solve these problems.One of the problems in the implementation of the GANP is that,on the one hand,there are currently no unified requirements for all categories of ATM personnel,and on the other hand,the development of ATM technologies is far ahead of the pace of training of personnel of appropriate qualifications.This problem becomes even more noticeable in countries that have just started an active modernization of ATC systems and do not have enough experience in this field.The paper describes the general methodological approach based on the education ontology modelling for human competency gap analysis in ATM and for gap analysis between the university curricula outcomes and the ATM requirements.The ontology of key personnel competencies issues for the design and integration of large-scale future ATM programmes is proposed.

Elucidating regulatory processes of intense physical activity by multi-omics analysis

Background:Physiological and biochemical processes across tissues of the body are regulated in response to the high demands of intense physical activity in several occupations,such as firefighting,law enforcement,military,and sports.A better understanding of such processes can ultimately help improve human performance and prevent illnesses in the work environment.Methods:To study regulatory processes in intense physical activity simulating real-life conditions,we performed a multi-omics analysis of 3 biofluids(blood plasma,urine,and saliva)collected from 11 wildland firefighters before and after a 45 min,intense exercise regimen.Omics profiles post-vs.pre-exercise were compared by Student’s t-test followed by pathway analysis and comparison between the different omics modalities.Results:Our multi-omics analysis identified and quantified 3835 proteins,730 lipids and 182 metabolites combining the 3 different types of samples.The blood plasma analysis revealed signatures of tissue damage and acute repair response accompanied by enhanced carbon metabolism to meet energy demands.The urine analysis showed a strong,concomitant regulation of 6 out of 8 identified proteins from the renin-angiotensin system supporting increased excretion of catabolites,reabsorption of nutrients and maintenance of fluid balance.In saliva,we observed a decrease in 3 pro-inflammatory cytokines and an increase in 8 antimicrobial peptides.A systematic literature review identified 6 papers that support an altered susceptibility to respiratory infection.Conclusions:This study shows simultaneous regulatory signatures in biofluids indicative of homeostatic maintenance during intense physical activity with possible effects on increased infection susceptibility,suggesting that caution against respiratory diseases could benefit workers on highly physical demanding jobs.
