The Effect Analysis of Aging Preparation Between National and Private Medical Workers
The purpose of this study is to find out the differences in between national and private medical institutions` perception towards aging, and to analyze how their different perceptions effect each of their later life preparation. A total of 783 questionnaires were distributed among national and private medical institution workers. Frequency analysis, t-test, hierarchical regression analysis was conducted from the collected data via SPSS 21.0. The results were the following. Firstly, there was a partial difference in their perception of aging, government policy satisfaction and later life preparation. National medical institutions were better than private medical institutions in all three terms. Also, perception of aging and government policy satisfaction were higher-than-average in both institutions, but in later life preparation, both scored lower-than-average. Secondly, the factors affecting preparation for aging were significantly different between these two institutions. Also, how each factors affected later life preparation was partially different. In conclusion, effects of factor was difference in aging preparation between national and private medical institutions workers. We need to provide as basic data for education and policy making for aging preparation.
Preparation for Old Age Life of Dental Hygienists
This study was carried out in order to seek social support direction by allowing them to recognize necessity of preparing for their stably old age life and by inquiring into the preparation for old age life targeting dental hygienists who work at dental clinics. It sent questionnaire by post to dental hygienists of 1,560 dental clinics, which were sampled with a stratified sampling method, and then conducted a cross-sectional study based on self-administration. As a result of a problem of being worried in old age life, the ratio with the response as saying of being `economy` was indicated to be the highest. The ratio of financial preparation for old age was shown to be high with 84.3%. Its method was the highest in `fixed deposit and installment savings` with 62.6%. The satisfaction with financial preparation for old age stood at averagely 2.60, thereby having shown to be dissatisfied. It was shown to be low with 2.97 in the mean score of physical preparation for old age life, 3.59 in emotional preparation, and 2.56 in preparation for leisure. In conclusion, the satisfaction with financial preparation for old age life in our country`s dental hygienists was low. Even the physical, emotional, and leisure-based preparations were shown to be low. Hence, it is considered to be likely needed to be planned preparation for old age life from the 30s. Also, for this, Korean Dental Hygienists Association needs to positively develop several kinds of programs such as education, policy and system for old age life following these people`s retirement.
Centrifuge modelling of effects of shield tunnels on existing tunnels in soft clay
With the rapid development of the subway network,the phenomena of shield tunnels going across the adjacent tunnels are becoming more and more common.The interaction between shield tunneling and nearby tunnels is more complicated than the ordinary shield tunneling in intact soil strata.Based on the project of Shanghai Bund Passage crossing Metro Line 2,the method of centrifuge modeling together with the field measurement is employed to study the effects shield tunneling on nearby strata and existing tunnels.In centrifugal model tests,the effects simulation techniques considering the unloading of excavation,ground loss and grouting are developed to analyze the longitudinal settlement of the shield tunnel and the existing tunnel induced by the shield tunneling.Besides,the deformation distribution and settlement curves of the existing tunnels during shield construction are studied by using the monitoring data.
