Purpose : This study was conducted to assess the status of sarcopenia and locomotive syndrome in the Korean elderly population over 65 years of age by applying the recently updated screening tool for diagnostic evaluation of sarcopenia and locomotive syndrome. Methods : Sarcopenia and locomotive syndrome (LS) were diagnosed and evaluated in 210 Korean elderly people over 65 years of age. There were 36 patients in the "sarcopenia group", 164 in the "locomotive syndrome group", and 10 in the "normal group". The collected data were analyzed using the chi-square and Kruskal-Wallis tests. Results : The diagnostic evaluation of sarcopenia and LS showed the presence of sarcopenia in 9.05 % of males and 8.10% females among the Korean elderly population over 65 years of age. Prevalence of stage 1 locomotive syndrome (LS 1) was 95.24 %; stage 2, (LS 2) 36.19 %; and stage 3 (LS 3), 16.19 % among the study population. Both the sarcopenia diagnostic indicator and the LS evaluation indicators showed significant differences between the three groups. All the subjects in the sarcopenia group had LS; further, on comparison of the detailed composition ratio of each patient with LS, the prevalence of LS in the sarcopenia group was found to be: LS 1 41.67 %, LS 2 41.67 %, and LS 3 16.67 %, whereas in the LS group, it was found to be: LS 1 66.46 %, LS 2 16.46 %, and LS 3 17.07 %. The difference between the two groups was statistically significant. Conclusion : It was confirmed that sarcopenia is correlated with LS incidence. This suggests that the evaluation of motor LS can be used as a tool for the early diagnosis and prevention of sarcopenia in cases of functional decline due to aging in the elderly population.

Creep is a major parameter to represent long-term behavior of concrete structures concerning serviceability and durability. The effect of creep is recently taking account into crack resistance analysis of early-age concrete concerning durability evaluation. Since existing creep prediction models were proposed to predict creep for hardened concrete, most of them cannot consider effectively the information on microstructure formation and hydration developed in the early-age concrete. In this study, creep tests for early-age concrete made of the type I cement and the type V cement are carried out respectively and creep prediction models are evaluated for the prediction of creep behavior in early-age concrete. A creep prediction model is modified for the prediction of creep in early-age concrete and also verified by comparing prediction results with results of creep tests on early-age concrete.

The evaluation items to assess the consumer needs are thought to be varied depending on their age, education and income. It should be noted that consumer needs are getting too diversified to notice them in time due to the rapid economic, social and cultural development. It is, therefore, considered improper to try to assess the level of consumer satisfaction and correct consumer needs by employing one evaluation method for the vastly diversified consumer types. This research is going to conduct a written questionnaire survey to the apartment dwellers in order to identify like dweller groups according to their age, income and education. Then the scope of personal characteristics of each group will be identified and the importance assessment model will be developed. Then the items on the POE will be weighted according to the assessed importance. Finally a method of developing the customer satisfaction index will be produced to quantify how much the consumers are satisfied with the project.
