Background/aims Conjunctival squamous cell carcinoma (CSCC) is the most frequent malignant tumour of the conjunctiva, with scarce recurrence and infrequent metastasis. The purpose of this study is to describe the clinical and pathological characteristics of this neoplasm and to identify the prognostic factors for recurrence and metastasis in a cancer hospital in Peru. Materials and method A longitudinal, retrospective study of 176 consecutive patients diagnosed with SCC of the conjunctiva. Sociodemographic and clinical characteristics were evaluated. In addition, Kaplan-Meier curves were performed, and Cox regression was used to determine prognostic factors for recurrence and metastasis over time. Result Only 12.5% presented tumour size ≤5 mm. The highest proportion according to the histopathological type was the well-differentiated infiltrative forms (40.9%), and according to tumour, node, metastases (TNM), stage T3 was the most frequent (31.3%). The most performed initial treatment was orbital exenteration (38.6%). The proportion of recurrence was 6.8% and 8.0% for metastasis. The annual survival rate was 7% and the annual metastasis rate was 6%; for recurrence after 5 years, the survival rate was 11% and the metastasis rate was 14%. No prognostic factor evaluated was significant. Conclusion This is the most extensive patient study in Latin America with CSCC, with a high proportion of advanced histopathological grade, TNM stages, and radical treatments such as exenteration. Recurrence rates on average are similar to other reported studies, and it describes the rates of metastasis that have been poorly described in the literature. / Revisión por pares

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2003. / Includes bibliographical references (leaves 96-104). / Over the next 30 years, the Boomers will double the 65+ population in the United States and comprise a new generation of older Americans. This study forecasts the aging Boomers' travel. Previous efforts to forecast 65+ travel are lacking in key two respects: they have failed to incorporate generation differences and have forecasted only broad travel characteristics (e.g. vehicle miles traveled). Drawing on the theory of generations, this study investigates empirically whether cohort differences in travel exist between the Boomers and the current 65+ population. It incorporates theoretically motivated cohort variables related to the historical processes of motorization, proxied by registered automobiles per person, and gender role evolution, proxied by labor force participation rates of women. The resulting forecast predicts the aging Boomers' travel demand with respect to activities requiring travel, person miles traveled, usage of transit and non-motorized modes, and trip chaining propensity. Data extracted from the 1977, 1983, 1990, and 1995 National Personal Transportation Surveys (NPTS) are used to estimate discrete and joint discrete/continuous demand models. Multiple imputation is used to impute missing survey data. Iterative proportional fitting is used to simulate future populations for forecasting purposes. Although 65+ travel is predicted to increase across all the modeled travel indicators, the results indicate that the current national forecast of 65+ travel prepared for the National Highway Traffic Safety Administration and the U. S. Department of Health and Human Services may overestimate future demand. The forecasts also suggest that investment in transit could increase 65+ transit usage propensities; opportunities for increasing transit viability are identified. / (cont.) Finally, in the estimated models, the cohort variables are significant, and with the exception of forecasted person-miles, cohort variable inclusion increases forecasted travel. The implication for transportation modeling is that historical location and generation membership affects transportation behavior. The implication for planners is that in preparing for future 65+ transportation needs, studying the current 65+ population is not adequate. The Boomers will comprise a new generation of 65+ with different associated travel needs. / by Sara Bush. / Ph.D.

According to the definition given by World Health Organization (WHO), if a country¡¦s percentage of people who are older than 65 years old is greater than 7% of total population, it is an aging society. Based on the forecast statistics for the aged population from the Ministry of Interior, Taiwan¡¦s aged population will rise to 14% in 2010 and will be over 20% in 2030. The fast growth of the aged population is a common social phenomenon around the world. Indeed, how to take care of the aged is an important issue, especially in Taiwan. Purpose: This research aims to understand problems of aging population, such as employment, medical care, care of the aged, long-term care, long-term family support, leisure, and education. The result of the study might serve as a reference for Kaohsiung city government in making caring policies for the aged population. Material and method: This study is conducted through deep interview and questionnaire. The content focused on Kaohsiung city government¡¦s caring policies for the aged population. 170 subjects received interview and questionnaire. 150 cases were obtained, 20 being excluded due to incomplete data. Result: (1) 34.7% of the Kaohsiung residents do not have the concept of the care of the aged and only 20% of the 50-to-60-year-old residents¡¦ plan their later life. (2) 30% of the Kaohsiung residents¡¦ first choice is living with their children and their next choice is living in the community (26%). The third choice is living in private nursing centers (18.7%). (3) 60.6% of old people are not willing to live in nursing centers. Discussion: In Taiwan traditional culture, people believe that the best life of the aged is living with children, playing with grand-children, and then died by nature. From the result of this study, Kaohsiung city government¡¦s caring policies for the aged population will achieve the goal to create a high-quality and peaceful environment.

Top Choice (n = 48) and Select (n = 48) paired bone-in ribeye rolls, bone-in strip loins, and boneless top sirloin butts were assigned randomly to one of two aging treatments (dry or wet) and aged 14, 21, 28 or 35 days. Sensory and Warner-Bratzler shear (WBS) evaluation was conducted to determine palatability characteristics. WBS values and consumer ratings showed wet-aged ribeye steaks to be more tender than their dry-aged counterparts. WBS values for ribeye and top sirloin steaks decreased with increased aging time. Consumer ratings for tenderness like increased with increased aging time for beef steaks from all three subprimals. No significant differences were found for consumer evaluation of top sirloin steaks. Top Choice ribeye and top loin steaks received higher consumer ratings for overall like and juiciness attributes when compared to Select steaks. Cutting tests were performed at the end of each aging period to determine retail yields and processing times. Retail cutting tests showed dry-aged subprimals had lower total saleable yield percentages and increased processing times compared to wet-aged subprimals. Cooler shrink and gross cut loss percentages increased with increased aging time for both Top Choice and Select subprimals.
