ABSTRACT
Objective To study the optical imaging quality of multifocal intraocular lens (IOL) following Nd∶YAG laser damage.Methods Three hydrophobic acrylate discs used to make multifocal IOL were placed in line,and the Nd∶YAG laser was used to emit the posterior surface,mid-plane and anterior surface of the discs by gradually increasing the emitting energy to determine the damaged threshold energy of various planes.Eight multifocal IOLs were divided into 2 groups.IOL damage models were established by emitting 12 points along 12 clocks on circle of 3.0 mm in diameter in the group 1 (IOLs NO.1,2,3,4) and 6 points with 1-clock interval on circle of 1.0 mm in diameter in the group 2 (IOLs NO.5,6,7,8) with Nd∶YAG laser.The modulation transfer function (MTF),line spread function (LSF) and United States air force (USAF) test target images of the IOLs were tested under the optical aperture at 2.0,3.0 and 4.5 mm.Results The damage thresholds of laser power were not significantly different among three hydrophobic acrylate discs (Fgroup =1.100,P =0.337),and the thresholds were significantly different among different planes in the discs (Fposition =195.279,P=0.000),with the highest damage threshold in the anterior surface and the lowest damage threshold in the mid-plane of the discs(all at P＜0.01).The shifts of far focus and near focus MTF curves,LSF curves and USAF target images of the IOLs under the 2.0,3.0 and 4.5 mm optical aperture after laser damage were in coincidence with those before laser damage both in group 1 and group 2.The glare phenomenon of the USAF target image was observed at near focus under the 4.5 mm optical aperture both before and after laser damage.Conclusions Multifocal IOL is vulnerable to injury when the laser beam focuses on the midplane,and the anterior surface of IOL can tolerate certain degree of damage.In standard model eye,the MTF curves,LSF curves and USAF target images of multifocal IOL was not impacted by laser induced spots injuries under different pupil diameters.
ABSTRACT
Objective To analyze the characteristics and changes in the disease spectrum of Air Force(AF) servicemen in order to provide reference for the determinatron of the overall level of health of AF and priorities of disease prevention and control.Methods The data of outpatient and inpatient diseases between 2009 and 2013 in AF was collected and analyzed statistically according to the International Classification of Diseases-9(ICD-9),and statistical description was performed with SPSS18.0.Results Between 2009 and 2013,unit B had the highest number of outpatients and inpatients,accounting for 47.74% and 39.64% respectively.The upper respiratory tract infections,gastroenteritis/gastritis,chronic low back pain,skin diseases,nasal sinusitis,training injury,trauma,hemorrhoids,varicocele and stone diseases were the common and frequently occurring diseases in AF,which were the top ten in the disease spectrum.Among them,the incidence and admission rate of skin diseases kept declining.However,the incidence of gastroenteritis/gastritis in unit A,the incidence and admission rate of chronic low back pain in unit B and D,the incidence of injury in unit D,as well as the incidence of neurological headache and hypertension in unit C and D were higher than in other units.Conclusion Respiratory system disease,and occupation-related diseases such as low back pain,training injuries,trauma,skin disease and digestive system disease are the focus of health care in AF.Health education and health promotion for these diseases should be improved,and health intervention for key populations should be enhanced.
ABSTRACT
Objective To analyze the results of the final aviation medical examination of 1281 students recruited into Air Force youth aviation schools in Hunan and Hubei provinces in order to provide reference for establishing the items and standards of medical selection .Methods The data of 1281 students who participated in final aviation medical examination of Air Force youth aviation schools in 2016 were collected , who came from 28 cities in the above two provinces .The disqualification rate and related unqualified medical items were calculated , and the differences of the disqualification rate and medical geographical areas in the 28 cities were analyzed .Results According to the disqualification rate , the top five departments were ophthalmology , otolaryngology, surgery, radiology and ultrasonic departments .The top 10 unqualified items were the lack of distant vision , fundus diseases , nasal anomaly , ametropia and strabismus , spine abnormality , audition abnormality, vestibular function badness , vitreous opacity, and lens abnormalities.There was no significant difference between the 28 cities in the disqualification rate (P >0.05) or between the two provinces (P >0.05). Conclusion The results of the final aviation medical examination reflect the quality and efficiency of the initial aviation medical examination .To improve the quality of medical selection , further research is needed to set a scientific standard for the initial aviation medical examination while strengthening the scientific protection and intervention of distant vision .The efficiency of selection depends on improving the accuracy of initial aviation medical examination in nasal cavity structure, body shape ,and lens opacity .With a better understanding of the disqualification rate and abnormal items in different cities , a scientific arrangement of professional staff and technical force can make the initial aviation medical examination better, thus effectively reducing the rate of false elimination rate and misdiagnosis .
ABSTRACT
Objective To reveal the difference between the standards for genu varum and genu valgum in the medical standard directory PLA Air Force( PLAAF) for recruitment of flying cadets and those adopted in the United States Air Force ( USAF) , and suggest a method for the reform of our flying cadets recruitment.Methods The rejection rate and comprehe nsive assessment qualification rate of genu varum and genu valgum during physical examinations for recruitment of flying cadets between 2012 and 2015 were analyzed.The different standards for genu varum and genu valgum in PLAAF and USAF flying cadets recruitment were compared and subjected to an empirical study.Results During the final physical examination for selection of flying cadets between 2012 and 2015, only 18 candidates were eliminated because of genu varum and genu valgum, accounting 9.1% of the total eliminated candidates because of orthopadics diseases.Four candidates with genu varum and genu valgum passed the comprehensive assessment in 2014 and 31 in 2015, which accounted for 15%of the candidates with orthopaedics diseases approved by comprehensive assessment.The standards for genu varum and genu valgum in PLAAF were based on morphology while those in the USAF based on the function of knees.According to the USAF medical standard directory, 9 of the candidates rejected because of genu varum and genu valgum were qualified and 9 disqualified.Among the candidates with genu varum and genu valgum approved by comprehensive assessment, 32 were qualified and 3 disqualified.Conclusion The standards for genu varum and genu valgum in PLAAF medical standard directory are of lower accuracy.The standards of USAF should be referred to and the function of knees should be considered in selection of flying cadets.Femur-tibia angle should be measured to improve the morphological standards.
ABSTRACT
El objetivo del presente estudio fue proponer un instrumento para medir el clima laboral en la Fuerza Aérea Colombiana. Para ello se diseñó el cuestionario de clima laboral, se evaluaron las características psicométricas y se estableció su utilidad como instrumento de medida. El estudio fue de tipo instrumental, con la participación de 3272 de sus funcionarios, diferenciados por grupos de rango, dependencia, jefatura y bases en el ámbito nacional. Se realizó el análisis de ítems para identificar la potencia discriminativa de cada uno de los ítems, para diferenciar entre quiénes tienen alta percepción de un buen clima laboral y los que no la tienen; la homogeneidad y la consistencia interna. Todas las escalas obtuvieron un alpha mayor a 0,72 y del análisis de cada ítem, se propone una escala de 58 elementos. Se concluye que el cuestionario de clima laboral tiene buena capacidad discriminativa y de homogeneidad.
The purpose of the study was to propose an instrument in order to measure the work environment in the Colombian Air Forces. In order to do this, a questionnaire of work environment was designed; then the psychometric characteristics were evaluated and the utility as an instrument of measurement was established. This study was instrumental and 3272 military servants took part in it and were classified according to their rank, branch where they work, if they were the chief of a division and location in the national territory. In order to identify the discriminative potential of each one of the items to differentiate among the military servants who have a high perception of a good work environment and those who do not have it, each item was analyzed. Homogeneity and inner consistency were also studied. All the scales got an alpha bigger than 0,72 and according to each item, a scale of 58 items is proposed. It was concluded that the questionnaire of work environment has a good homogeneity and discriminative capacity.
ABSTRACT
O artigo apresenta parte dos resultados de um estudo realizado com seis mulheres oficiais formadas na primeira turma do curso de aviação da Aeronáutica. Seu objetivo foi investigar como elas vivenciam a experiência de uma carreira até então vedada a mulheres, como percebem a hierarquia e as relações de poder típicas dessa carreira, e quais os seus projetos profissionais e pessoais para o futuro. Utilizamos entrevistas semiestruturadas, que foram gravadas e transcritas na íntegra; os textos resultantes foram submetidos à análise de discurso. Pudemos constatar nos relatos das entrevistadas a coexistência de padrões contemporâneos e arcaicos; ou seja, ao mesmo tempo em que, de forma pioneira, estão investindo em uma carreira profissional até então aberta apenas aos homens, continuam a sonhar com o casamento e a maternidade nos moldes tradicionais, reforçando a ideia de que a mulher é responsável pelos cuidados com a casa e a criação e educação dos filhos.
This article presents part of the results of a study developed with the first Brazilian Air Force women pilots. Its objective was to investigate how they experience the career until then prohibited to women, how they perceive the hierarchy and power relations typical of that professional realm, and what they project for their future. We interviewed six women pilots, whose reports were audio recorded, transcribed, and submitted to discourse analysis. Such analysis pointed to the fact that contemporary and traditional patterns of behavior coexist. At the same time those women invest in a pioneering professional career and search for financial independence, they continue to dream about marriage and motherhood in traditional formats, reinforcing the idea that women are the main responsible for household care and for raising and educating the children.

ABSTRACT
BACKGROUND: Though nursing officer system was introduced to ROKAF with the changes in ROKAF's medical environment and expectations toward nursing profession, its role is not clearly defined yet and this leads to the necessity of further research on systematic role development. This work, therefore, tried to supply basic information for its role development by finding out role expectations on nursing officer in ROKAF Base from air force members. METHODS: Surveys were conducted from Oct. 10 to Oct. 25, 2002 on three groups in ROKAF air bases: nursing officers, medical team and consumers of nursing services. For data collection, survey instrument was developed through research surveys and delphi method. Data were analyzed with SPSS Win 10.1. RESULTS: Results of the study is summarized as follows; 1) Surveys were conducted on 169 persons : consumers 109 (64.9%), medical team 32 (18.9%), and nursing officers 28 (16.6%). 2) The type of that nursing officers assumed were conducting are clinician, educator, researcher, consultant, administrator and military officer. 3)The degrees of role expectation on above roles were highest in nursing officers, followed by medical team and consumers. In detail, for the nursing officers group, the order was clinician (3.68+/-21), researcher (3.62+/-35), educator (3.59+/-27), consultant (3.42+/-43), administrator (3.42+/-39) and military officer (3.30+/-34). For the medical team group, the order was researcher (3.49+/-41), educator (3.48+/-49), clinician (3.38+/-37), military officer (3.23+/-45) and consultant (3.17+/-56). For the consumers group, the order of role expectation is researcher(3.18+/-48), clinician (3.14+/-39), consultant (3.12+/-53), military officer (3.10+/-48), educator (3.09+/-49) and administrator (2.93+/-44). All of the roles were defined as necessary by the three surveyed groups except the consumer group for the role of administrator. There were significant differences in the role expectation, between medical team group and nursing officers group, for the role as a whole (t=-2.46, P=.017) and for the role as clinician specifically (t=-3.79, P=.000). DISCUSSION: Based on the research results, I propose that clinician, educator, researcher, consultant, administrator and military officer the role of assumed by nursing officers in air base should be defined. Since role establishment and proper execution requires more comprehensive research to cope with excluded roles and on related matters such as personnel, organizational system, institution and regulation, inter-disciplinary studies are necessary.

ABSTRACT
The survey of occupational injury has not been performed in Korean Air Force. The aim of this survey is to identify the feature of the occupational injury at the Korean Air force base. The occupational injury were monitored at the medical group in a Korean air base, from Aug 1998 to Jul 1999. Because the medical group has supported 2 different groups, we analysed and described some results seperately; group 1 consisted of workers in line maintenance operation, group 2 included workers in base maintenance operation. There were 59 injuries(injured persons) in group 1, and 9 injuries in group 2, so the incidence(per 1000) were 21.5, 4.46 respectively. 11 persons transferred to well-equiped hospital. Most of injured persons were air men, and then sergeant, civilian employee in order. The median age of injured persons was 22 years old in group 1 and 21 years old in group 2. The median work experience was 0.8 and 8 years respectively. The median delay time to arrive at the hospital from the time of injury were 30 min in group 1, 20 min in group 2, but maximum delay in group 1 was about 9 days. The occupational injuries were most common in October in the year, Tuesday in a week. Also the injury occurred common from 13 to 13:59, and from 11 to 11:59 in a day. The injury occurred most commonly by the collision with something, when working with more than 4 coworkers, and repairing the machinery. The most common injured part of the body were hands and feet, the patterns of injury were laceration and fracture.
