Objectives: This study aims at making of cognitive function, barthel activities of daily living and self-perceived health toward elders and demented elders. Methods: The subjects were 50 elders who resided in Seoul, Cheongju, Wonju, Yongin, Jecheon and 56 demented elders who entered 3 randomly selected geriatric hospitals in Seoul, Yongin, Data were collected using questionnaires and interviews from March through May, 2011 T-test, Analysis of variance (ANOVA) were adopted in data analyses, Results: Most of the demented elders were diagnosed with Alzheimer`s disease and had another diseases. There was significant difference of cognitive function, barthel activities of daily living between both elderly groups. But there was no significant difference of self-perceived health between both elderly groups. Conclusions: To make generalizations of the results, replication studies are needed. And the significant difference of cognitive function between both elderly groups means that this thesis supports the studies considering the suspicious groups of dementia with CDR 0.5 the portion of normal process of aging.

Objectives: The purpose of this study was to find out how to affect of the elderly`s recognition and action on body image to successful aging between high level group of perceived health and low level group. Methods: The 297 survey samples were divided into high level group and low level group in terms of the perceived health. T-test was exploited to see the differences of extemal image and successful aging between two groups. Correlation and hierarchical regression were applied to see how the socio-economic and the external image influence the successful aging. Results: First, results showed the high level group of perceived health was significantly higher perception of self-other recognition, external image, appearance management and the elderly`s perception of successful aging than the low level group. Second, the high level group of perceived health showed the higher effect of socio-economic variables and the extemal image`s perception and management to the successful aging than the low level group. However, the low level group of perceived health perceived the external image and management was important to the successful aging. Conclusions: It is suggested to develop some programs and policies for improvement of external image and management in the context of successful aging.

Objectives: The study aims to identify and discuss the concept of the key assumption on which the indirect comparisons rely and to illustrate a practical approach to assure the validity. Methods: We firstly reviewed the theoretical background of the indirect comparisons and then suggested how the key assumptions can be assessed and accounted for using an example of common reference based indirect comparison. Results: The fundamental assumption behind the synthesized comparative effect obtained by indirect comparison is that the same effect would still be obtainable if it was directly measured in all of the trials that constitute the indirect comparison. An illustrative analysis demonstrated that conducting an indirect comparison without a meticulous assessment for the exchangeability could mislead the conclusion on the comparative effectiveness. Conclusions: Head-to-head trials could provide the most valid estimate of the comparative effect of a healthcare intervention. When competing interventions have not been evaluated in direct randomized trials or there is little available source by those trials, indirect comparisons may be utilized to provide an estimate of the comparative effect. However, the limitations also need to be highlighted, since the indirect comparison methodology relies upon certain important but conceptual and essentially unverifiable key assumption.

Objectives: The origin of medicinal herbs is crucial to quality control. We aimed to find statistical model to discriminate the origin of boxthron. Methods: We used three types of methods for choosing meaningful variables that to predict the origin of boxthron: standardization, binning, variable selection. Firstly we used LRPC (Iogistic regression model with principal components) and PLSR (partial least square regression) model to discriminate the origin of spectrum pattern, and then figured chemical substance out. Results: We compared prediction power of alternative models according to three factors: variable selection, standardization and modeling. Variable selection method was worse than modeling using all variables. An error rate of the first type of standardization showed the best results among three standardization types. PLSR lower rate of error compared to LRPC. Optimized model, through LOOCV (leave and out cross validation), predicted the time that find out Boxthron origin, and also differentiated the orogin of Boxthron by Glycerol (14.3 seconds) and malic acid (23.18 seconds). Conclusions: We identified and suggested statistical model to discriminate the origin of boxthron by simulation. However, further research is needed to enhance the rate of prediction.

Objectives: In this study, we newly proposed to apply multiple logistic regression with elastic-net regularization to identify metabolomic markers that predict origins of herbal medicines. Methods: Herbal medicines were collected from two different origins, Korea and China. For each origin, 30 samples were extracted and profiled by nuclear magnetic resonance (NMR) technology, After binning and normalization, we obtained 60 profiles containing density of 240 metabolites, Logistic regression was applied with elastic-net regularization to identify metabolomics markers and build a classifier. We compared the performance of our classifier with the classifier based on orthogonal partial least squares-discriminant analysis (OPLS-DA), which has been commonly used in metabolomics. Results: A total of 14 metabolomic markers were selected to construct the classifier discriminating Korean and Chinese herbal medicines. In predicting the origin of additional samples, our classifier had no misclassification, while the OPLS-DA classifier showed 25˚ o misclassification rate. Conclusions: These results suggest that our method would have advantages against the OPLS-DA, including lower misclassification rate, better interpretability, and no need of an additional analysis for marker identification.

Objectives: We review the statistical considerations for superiority trial to design appropriate statistical hypothesis and decision-making. Methods: We plan superiority design especially for placebo-controlled trial or combination drug trial. Many previous studies employed two-sided hypothesis testing and misuse of significance level, and this resulted in wrong sample size and confidence interval. Therefore we compared sample size estimation and confidence interval according to one-sided and two-sided hypotheses, Results: There are differences in sample size estimation and confidence interval according to one-sided or two-sided hypotheses with the pre-determined power at the significance level, Conclusions: For superiority trial in the confirmatory stage, one-sided hypothesis is advisable, We can estimate a sample size from this hypothesis and recommend to use a confidence interval for decision-making.

Objectives: It has been proven that doing exercise regularly is effective in lowering the risk of cardiovascular disease. The purpose of this study is to evaluate the relationship between physical activity and the cardiovascular risk factors. Methods: The study samples were 404 men and women who went to Yonsei Fitness Center from May of 2009 to April of 2010. We tried to assess the relationship between physical activity and cardiovascular risk factors. We used paired t-test and multiple regression, Results: The result showed that the significant relationship between the mean value of body weight and the frequency of gym visit in men (mean of 75.9±8.3 in 2009 vs. 74.1±8.6 in 2010 (p=0.0067). Men who used 90 times in gym showed a significantly lower risk (GOT: p=-7.76978, p=0.0 629 GPT: 13=-12.45055, p=0.0003 GGT: p=-9.94185, p=0.0 194) of liver function vs. those who used 1-29 times. Women who used 60 times in gym showed a significantly lower risk (total cholesterol: 13=-28.265l3, p=0.0066; LDL cholesterol: 13=-23.69l64, p=0.0071) of lipid profile vs. those who used 1-29 times. Conclusions: Increased physical activity influences in lowering body weight, lipid profile and improving liver function. We need to conduct follow up research about physical activity program in the work place.

Objectives: This research tries to evaluate proper analysis sets for matched-pair noninferiority clinical trials based on Sanchez and Chen`s work (2006). Methods: We evaluate intention-to-treat (ITT) with last observation carried forward (LOCF), ITT with mixed model for repeated measures (MIVIRM) and per-protocol (PP) using simulation study wit various scenarios. Results: From the simulation study, it is found that LOCF is simple and convenient to handle missing data, but it should be used with caution because it can result in biased effect estimation and lack of control on Type I error. On the other hand, ITT-MMERM has more control over Type Tenor and bias compared with ITT-LOCF and PP. Conclusions: In matched-pair noninferiority clinical trials, ITT with consideration of MMRM can be recommended for the primary analysis.

Objectives: The purpose of this study is to explore how to use the estimation of supply and demand on burial and cremation for planning the long-term strategies of funeral facilities. Methods: This study consists of three directions. First, the population and the number of deaths were estimated, and how to estimate future population and the future number of deaths for potential users was explained. Second, the burial rate and cremation rate were estimated respectively, and how to use the Gompertz curve, to estimate potential users was explained. Third, using the results obtained, in the past, the supply and demand on funeral facilities were estimated. This includes the annual estimation of supply and demand on burial facilities and private enshrinement facilities. Results: The funeral facilities in Gyeonggi-do were analyzed and the types of installation were presented. In this in- depth research, most of all, the space for cemetery is relatively limited in Gyeonggi-do. There are sufficient urn facilities compared with the cemetery facilities in 2008. Conclusions: The solution to reduce inconvenience due to the lack of cemetery facilities needs to be found, and the natural ways to minimize damage and how to install green burial should be considered. The utilization of the Gompertz Curve has proved effective on the estimation of funeral facilities.
