The purpose of this study is to evaluate the relationship of blood pressure with dietary habit and level of physical fitness of middle-aged male workers by age. The study subjects included 511 male employees who have worked at a company in C City, whose age was more than 40 years old. Between April 10 and May 30. 1998, all of the study subjects measured physical fitness (Balance, strength, power, agility, flexibility and endurance) and blood pressure. A questionnair was administered for dietary habit and socio-demographic characteristics. The average age (SD) of the study subjects was 46.61(3.98) years. The study subjects were classified by age into 3 groups; 40-44 aged group(34.6%), 45-49 aged group(41.3%), and 50-54 aged group (24.1%). The score of dietary habit of 40-44 aged group was $69.77{\pm}5.82$. that of 45-49 aged group was $69.77{\pm}5.83$, and that of 50-54 aged group was $71.85{\pm}6.82$(p=0.005). But age of health physical fitness tend to weaken in the age of 40-44. Systolic(p=.011) and Diastolic blood pressure (p= .011) were significantly increased with age increment. Diastolic blood pressure and dietary habit of 45-49 aged group showed the significant negative-correlation(r= .280. P<0.05). and Diastolic blood pressure and age of health physical fitness of 40-44 aged group showed the significant positive-correlation(r= .182. P<0.05). On the basis of the results of this study. I hope occupational nurses should play an active role to improve dietary habit and physical fitness for prevention of hypertension with increase of age in middle-aged male workers.

Purpose: The purpose this study was to evaluate the marginal fitness of metal copings fabricated using rapid prototyping method and to compare the fitness with copings by conventional method. Then clinical availability of fixed dental prostheses (FDPs) fabricated using rapid prototyping method shall be confirmed based on marginal fitness. Methods: Ten same cases of3 unit FDPs epoxy models (abutment teeth 14 and 16) were manufactured. Each of ten epoxy models were scanned by 3shape D-700 scanner to be designed by experienced technician, and photopolymer 3 unit FDPs were fabricated using rapid prototyping methodand fabricated using Lost wax technique (LW) with same models. Marginal fitness of 3 unit FDPs were measured by silicone replica technique. T-test of independent sample for statistical analysis was executed with SPSS 12.0K for Windows. (${\alpha}$=.05) Results: Significantly higher mean (SD) marginal fitness (P<.000) were observed in the RP group $(95.9(18.0){\mu}m$ compared to the conventionally LW group $(80.1(13.8){\mu}m$. Conclusion: Marginal fitness of LW group showed excellent rather than RP group. However marginal fitness of 3 unit FDPs fabricated by RP method did not get out of clinical allowance value range significantly to allow clinical application.

Background: Recommendations have been proposed for minimum aerobic fitness among firefighters but it is unclear if those criteria relate to performance on the fireground. Less fit individuals fatigue more quickly than fit individuals when working at comparable intensity and may have gait changes, increasing risk of falls. We evaluated the effect of fatigue during a live burn evolution on gait parameters and functional balance comparing them to aerobic fitness levels. Methods: A total of 24 firefighters had gait and balance tested before and after a live burn evolution. Data were stratified by aerobic fitness of greater/less than 14 metabolic equivalents (METs). Results: Analysis of gait cycles measurements before and after the live burn evolution revealed that single leg stance, cycle, and swing time decreased (p < 0.05) but there were no differences in the other measures. There were no differences in time to complete the functional balance test, or errors committed before or after a live burn evolution. When firefighters were sorted by fitness level of 14 METs, there were no differences for errors or time before or after the live burn evolution. Balance data were analyzed using a linear regression. Individuals with lower fitness levels required more time to complete the test. Conclusion: A 14-MET criterion failed to distinguish gait or balance characteristics in this group. However, less fit firefighters did require more time to complete the balance test (p = 0.003). Aerobic fitness alone does not predict gait changes among firefighters following a live burn evolution but does appear to influence functional balance.

There is growing interest in the use of cloud services these days because the amount of sensitive physical information related to u-fitness-based exercise management increase in explosive. However, it is possible to illegally access information stored in a cloud server, and to find out who owns the information, even, to illegally deduce an association among the information stored in its memory. The cloud server may also intentionally pass over the owner's legitimate operation requests such as modification and deletion of stored information, and may lose or damage information due to its malfunction. So, it is strongly required to solve the above problems because we can not trust the cloud server entirely. In this paper, we propose a protocol to preserve the privacy of the owner for u-Fitness-based exercise management in a cloud computing environment. And we show that our proposed architecture is applicable in real environment through security analysis and performance analysis.
