UNLABELLED:The purpose of this study was to assess the prevalence of sagittal lumbar spine postural abnormalities and associated factors among students in the federal educational system in Florianópolis. METHODS:288 adolescents (156 males and 132 females), aged from 15 to 18 years, who were students in the federal educational system in Florianópolis, Santa Catarina, were evaluated. To gather data, photogrammetry was used following a specific protocol for postural assessment, and a questionnaire was used to identify the prevalence and frequency of pain, and the activities that triggered the problem. In the data analysis, descriptive statistics, Student's t-test for independent samples, chi-square test and Poisson's regression were used, with the significance level set at p<0.05 for all the tests. RESULTS:The prevalence of low back pain was 49.3%, with weekly frequency in 43.1% of the sample. The prevalence of deviation was 53.8%, and 90.9% corresponded to rectification of lumbar curvature, and this affected males more frequently. A significant difference in lumbar angle was found between the sexes; higher prevalence ratios of postural deviations were found in the male group. CONCLUSIONS:The prevalences of low back pain and lumbar postural deviation were high, but the relationship between these variables did not present significance. The main causes of the lumbar pain were sports practice or vigorous activities and remaining in a seated position for extended periods of time.

From the assumption that mariculture is increasing,this paper discusses proposals for the ergonomics contribution into sustainable development of Small Groups Productive with family characteristics(GPPPf).The results have been indicated the adoption of techniques and knowledge involved in ergonomics domains,especially in the areas of physical ergonomics and organizational ergonomics within the production engineering,without neglecting other *** aspects aim to engage people,the productive activity,and the environment,related to the mussel perna perna cultivation,as a proposal to incorporate social,economic and environmental dimensions of sustainability.

NAVAL ENGINEERS JOURNAL 1996年第1期108卷 61-72页

作者： Calvano, CN Riedel, JS Professor Charles N. Calvano Capt. USN (Ret.): of the Naval Postgraduate School is responsible for a program in Total Ship Systems Engineering. He is a graduate of the Naval Academy who served as a surface warfare officer. After completion of his graduate education at MIT he became an Engineering Duty Officer and served at Boston Naval Shipyard in several capacities. He was the Repair Facilities Advisor to the Vietnamese Navy the Project Officer for construction of nuclear powered guided missile cruisers (CGNs) at the Supervisor of Shipbuilding Newport News Virginia and served on the staff of the Commander Naval Surface Forces U.S. Atlantic Fleet and later at the Supervisor of Shipbuilding in Portsmouth Virginia in maintenance and overhaul management positions. He was Officer in Charge of the Annapolis Laboratory of the David Taylor Research Center and Commanding Officer of the Engineering Duty Officer School. He retired from active duty in October 1991 after serving in the Naval Sea Systems Command as the Director of the Ship Design Group and of the Advanced Concepts and Technology Group. Lt. Jeffrey S. Riedel USN:is an Engineering Duty Officer currently assigned to the Supervisor of Shipbuilding Bath Maine. He obtained his B.S. degree in Marine Engineering from Maine Maritime Academy in 1986 and his M.S. degree in Mechanical Engineering plus a Mechanical Engineer's degree from the Naval Postgraduate School in 1993. Lt. Riedel's naval career has included duty aboaqrd USS Wainwright (CG 28) as auxiliaries officer damage control assistant and main machinery officer. Currently he serves as the assistant production officer at SUPSHIP Bath in charge of DDG 51 class construction and delivery.

This paper describes the design of a Regional Deterrence Ship (RDS 2010) for the 2010 timeframe. The requirements for the design were for a ship to operate in littoral areas of the world with a mission of deterring regional conflicts and of hampering the efforts of the aggressor in such a conflict. In addition the ship's mission included the evacuation of friendly personnel as hostilities become likely. The problem countering the littoral threat during times of constrained budgets is addressed. Top level requirements for the design, generated in parallel with ''.... From the Sea'' [1], were used to set the design goals. The paper describes the manner in which littoral warfare changes the nature of the challenges faced by Navy surface combatants, including a ship such as the RDS 2010. A number of factors become more crucial design concerns than for blue water ships, including reduced reaction times, likelihood of attack from hidden land sites, shallow water mines and shallow water USW Certain other factors become less critical in littoral areas and this also has ship design impacts. While some present ship designs can perform some of the tasks needed in a littoral warfare/regional conflict environment, none represents a completely integrated design (hull, mechanical & electrical;combat systems;fiscal and manning constraints;reduced vulnerability;robust self-defense etc.) for a vessel stationed in waters that, without warning, can become hostile. After describing the mission requirements to which the RDS 2010 was designed, the paper discusses the controlling design philosophy and decisions and describes the process used to assess threats to the ship. The process of combat system selection, against the backdrop of expected threat scenarios, is described and the intended approach to integration of the combat system is discussed. In recognition that decreased reaction times and surprise attacks are likely to threaten a ship engaged in regional deterrence, discussions oi
