High-intensity Fitness Training Among a National Sample of Male Career Firefighters
Jahnke, Sara A.,Hyder, Melissa L.,Haddock, Christopher K.,Jitnarin, Nattinee,Day, R. Sue,Carlos Poston, Walker S. Occupational Safety and Health Research Institute 2015 Safety and health at work Vol.6 No.1
Obesity and fitness have been identified as key health concerns among USA firefighters yet little is known about the current habits related to exercise and diet. In particular, high-intensity training (HIT) has gained increasing popularity among this population but limited quantitative data are available about how often it is used and the relationship between HIT and other outcomes. Using survey methodology, the current study evaluated self-reported HIT and diet practice among 625 male firefighters. Almost one-third (32.3%) of participants reported engaging in HIT. Body composition, as measured by waist circumference and percentage body fat, was significantly related to HIT training, with HIT participants being approximately half as likely to be classified as obese using body fat [odds ratio (OR) = 0.52, 95% confidence interval (CI) = 0.34-0.78] or waist circumference (OR = 0.61, 95% CI = 0.37-0.98). Those who engaged in HIT were more than twice as likely as those who did not (OR = 2.24, 95% CI = 1.42-3.55) to meet fitness recommendations. Findings highlight directions for future prevention and intervention efforts.

Hannelore LEE-JAHNKE, (2006). Is there an Ideal Curriculum for the Training of Translators?. Interpreting and Translation Studies 10-1, pp.133-171. 번역사, 가장 긴 역사를 가진 직업 중에 하나임에도 정작 그 교육의 역사는 일천하다. 그리고 그 출발점에는 번역 교육이 과연 가능한 것인가에 대한 근본적, 존재론적 물음이 존재하였다. 그러나 번역 이론의 대두를 통해 이를 긍정할 수 있게 되었고, 나아가 번역 교육의 이상향을 찾는 여정이 시작되었다. 여기에 함께한 몇몇 학자들은 그 첫 번째 기착지로 교과 과정 설계를 선택하였다. 그렇다면, 이상적인 번역 교과 과정은 존재하는가? 번역 교육에 필요한 기본 소양을 검증할 입학 시험, 풍부한 실무 경험을 갖춘 교강사진은 물론, 전공 언어 숙달, 최신 테크놀러지, 다양한 주제 분야에 관한 강의 등 응당 합의된 번역 교과 과정의 필요 조건을 넘어, 강도 높은 번역 교육의 시행과 맞물려 학술적 관심은 과정 중심 번역 교육(process-oriented translation training)으로 이동하였다. 양질의 목표 텍스트를 산출하는 과정에 대한 이해를 심화함으로써 궁극적으로는 번역 교육에의 함의를 모색하려는 과정 중심 연구에서는, 인지 과학의 힘을 빌어 오기도 한다. 이를 통해 학생, 지식, 교수의 3대 축으로 구성된 번역 교육에서 심적 표상(mental representation), 추론력, 평가적/예측적 판단력, 유추력 등의 인지 과정을 분석할 수 있기 때문이다. 예컨대 필자는 전공 언어 숙달의 정도에 따라 번역 과정에서 발생하는 휴지(pause)의 빈도와 시간의 차이를 ‘Translog’ 소프트웨어를 통해 분석함으로써, 이것이 용어, 표현 등 번역 품질에 어떤 영향을 주는지를 연구하고 있다. 요컨대 이와 같은 노력을 계속함으로써 적절한(proper) 번역 교육을 구현한다면, 이상적인 번역 교과 과정의 존재 여부를 묻는 질문에 긍정할 수 있을 뿐만 아니라 나아가 적재적소에서 일할 번역사를 양성한다고 자부할 수 있다.
Le defi de la formation des traducteurs
( Hannelore Lee Jahnke ) 한국통역번역학회 2004 FORUM Vol.2 No.1
Which are the factors that allow the most adequate training of translators? In other words, a training which satisfies market needs. This presupposes to know about these needs which are in permanent change. Students have to be trained in Quality, Flexibility and Efficiency. This requires evaluation instruments- especially for formative evaluation. We wish to offer some examples of such instruments and ask the somewhat delicate question of the competence of the trainers.

Efficient Excitonic Photoluminescence in Direct and Indirect Band Gap Monolayer MoS<sub>2</sub>
Steinhoff, A.,Kim, J.-H.,Jahnke, F.,Rö,sner, M.,Kim, D.-S.,Lee, C.,Han, G. H.,Jeong, M. S.,Wehling, T. O.,Gies, C. American Chemical Society 2015 NANO LETTERS Vol.15 No.10
<P>We discuss the photoluminescence (PL) of semiconducting transition metal dichalcogenides on the basis of experiments and a microscopic theory. The latter connects ab initio calculations of the single-particle states and Coulomb matrix elements with a many-body description of optical emission spectra. For monolayer MoS<SUB>2</SUB>, we study the PL efficiency at the excitonic A and B transitions in terms of carrier populations in the band structure and provide a quantitative comparison to an (In)GaAs quantum well-structure. Suppression and enhancement of PL under biaxial strain is quantified in terms of changes in the local extrema of the conduction and valence bands. The large exciton binding energy in MoS<SUB>2</SUB> enables two distinctly different excitation methods: above-band gap excitation and quasi-resonant excitation of excitonic resonances below the single-particle band gap. The latter case creates a nonequilibrium distribution of carriers predominantly in the K-valleys, which leads to strong emission from the A-exciton transition and a visible B-peak even if the band gap is indirect. For above-band gap excitation, we predict a strongly reduced emission intensity at comparable carrier densities and the absence of B-exciton emission. The results agree well with PL measurements performed on monolayer MoS<SUB>2</SUB> at excitation wavelengths of 405 nm (above) and 532 nm (below the band gap).</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2015/nalefd.2015.15.issue-10/acs.nanolett.5b02719/production/images/medium/nl-2015-02719d_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl5b02719'>ACS Electronic Supporting Info</A></P>
Cancer Perceptions Among Smokeless Tobacco Users: A Qualitative Study of US Firefighters
Jitnarin, Nattinee,Poston, Walker S.C.,Jahnke, Sara A.,Haddock, Christopher K.,Kelley, Hannah N. Occupational Safety and Health Research Institute 2020 Safety and health at work Vol.11 No.3
Background: Prevalence rates of smokeless tobacco (SLT) use among firefighters are remarkably high and substantially higher than similar occupational groups and the general U.S. population. The purpose of this study was to explore the perspectives of fire service personnel regarding cancer and its associations with tobacco and SLT use. Methods: This descriptive study used a qualitative approach. Key informant interviews were conducted in 39 career firefighters and fire service administration from across the U.S. Discussion were recorded, transcribed verbatim and transferred to NVivo software for narrative analysis. Topics explored included cancer perceptions, attitudes and beliefs, and cultural factors related to SLT use behaviors. Results: Major themes that emerged among fire service personnel included concerns about cancer and its risk factors including firefighting tasks, such as fire overhaul operations, and from their lifestyle behaviors, such as alcohol and tobacco use. Firefighters also suggested a number of reasons for their increased SLT use, such as fire department tobacco-free policy and fire service culture. Conclusion: The current study provides a rich foundation for future research, prevention, and intervention efforts for the fire service and research communities regarding tobacco and SLT use and cancer risk. Additional research on firefighters' cancer beliefs deserves future research in order to improve messaging about the risks of cancer due to firefighting.
Targeting Bcr–Abl by combining allosteric with ATP-binding-site inhibitors
Zhang, Jianming,Adriá,n, Francisco J.,Jahnke, Wolfgang,Cowan-Jacob, Sandra W.,Li, Allen G.,Iacob, Roxana E.,Sim, Taebo,Powers, John,Dierks, Christine,Sun, Fangxian,Guo, Gui-Rong,Ding, Qiang,Okra Macmillan Publishers Limited. All rights reserved 2010 Nature Vol.463 No.7280
In an effort to find new pharmacological modalities to overcome resistance to ATP-binding-site inhibitors of Bcr–Abl, we recently reported the discovery of GNF-2, a selective allosteric Bcr–Abl inhibitor. Here, using solution NMR, X-ray crystallography, mutagenesis and hydrogen exchange mass spectrometry, we show that GNF-2 binds to the myristate-binding site of Abl, leading to changes in the structural dynamics of the ATP-binding site. GNF-5, an analogue of GNF-2 with improved pharmacokinetic properties, when used in combination with the ATP-competitive inhibitors imatinib or nilotinib, suppressed the emergence of resistance mutations in vitro, displayed additive inhibitory activity in biochemical and cellular assays against T315I mutant human Bcr–Abl and displayed in vivo efficacy against this recalcitrant mutant in a murine bone-marrow transplantation model. These results show that therapeutically relevant inhibition of Bcr–Abl activity can be achieved with inhibitors that bind to the myristate-binding site and that combining allosteric and ATP-competitive inhibitors can overcome resistance to either agent alone.
