While variety of content on the internet has increased with the development of IT and person's needs about suitable information are increasing rapidly, studies for personalized service have been actively performed. In the study, we proposed the Hypertension and Diabetes risk analysis system according to personal food intake preference using the analysis method of buying preferences in product recommendation system. For the analysis of food intake preference, the Pearson correlation coefficient is used to calculate similarity weights between each reference analysis data and sample data and then reference data should be grouping into the similarity weights and calculating risk of hypertension and diabetes each group. To evaluate the significance of this system, 1,021 subjects are applied the system. Hypertension and diabetes groups' risk is significant higher than normal group statistically so, it is confirmed that food intake preference and the diseases were relevant. In this paper, we verify the validity of hypertension and diabetes risk analysis system using a personal food intake preference.

In order to produce the variety of UCC, the recommendation service is required which considers the copyright of UCC producer discriminated from one for UCC consumers and the purpose of its production. The recommender system designed in this thesis enables UCC which is much similar to one UCC producer utilizes to be used with custom-made when recommending and producing based on UCC view history and production list, etc. of its producer. The recommender system is largely divided into filtering based on the preferred tag, UCC filtering used when producing the preferred UCC and creating process of recommended UCC using the Pearson formula. The recommender system in this thesis requires the data which were used when producing UCC. For that, we added the reference factor so that the data of UCC which were utilized when producing UCC into the existing metadata can be recorded. If the recommender system suggested in this thesis is used, the more effective and convenient UCC recommendation services with custom-made for producers can be provided.

Objectives This study analyzed the correlation between lumbar spine and pelvic body parameters measured using body shape analysis system and X-ray view. Methods Body shape analysis system and X-ray view were performed for 100 patients to diagnose subluxation using body parameters such as pelvic obliquity angle, anterior superior iliac spine to posterior superior iliac spine angle (ASIS-PSIS angle), lumbar lateral flexion angle. The correlation analysis using body parameters obtained through the body shape analysis system and X-ray view was performed by measuring the Pearson correlation coefficient, a parameter test. Results Significant correlations were observed between the values for pelvic obliquity angle, ASIS-PSIS angle, lumbar lateral flexion angle measured by X-ray view and body shape analysis system. The most significant correlation was observed in the value of pelvic obliquity angle. Conclusions Body parameters and posture analysis measured by the body shape analysis system can be used in place of X-ray view. Additional research and samples are still necessary.

A systematic procedure of probability analysis for general distributions is developed based on the first four moments estimated from polynomial interpolation of the system response function and the Pearson system. The function approximation is based on a specially selected experimental region for accuracy and the number of function evaluations is taken equal to that of the unknown coefficient for efficiency. For this purpose, three error-minimizing conditions are proposed and corresponding canonical experimental regions are formed for popular probability. This approach is applied to study the stochastic properties of the performance functions of a MEMS structure, which has quite large fabrication errors compared to other structures. Especially, the vibratory micro-gyroscope is studied using the statistical moments and probability density function (PDF) of the performance function to be the difference between resonant frequencies corresponding to sensing and driving mode. The results show that it is very sensitive to the fabrication errors and that the types of PDF of each variable also affect the stochastic properties of the performance function although they have same the mean and variance.

In the current study, we measured the hands and other representative body items of 223 elementary school girls using Martin Anthropometer and a digital camera so that we would be able to provide information on both size and shape of hands for design of hand-related products. As time goes on, hands get bigger, yet they get thinner at the same time. The data implies that the frame of hands grows, but the skin fat lessens, which could be a determinant factor in the size system of hand-related products. According to the results of a factor analysis on 26 hand items, 5 factors including hand laterality and linearity, fingertip shape, finger breadth, and hand depth, have been extracted. Pearson's correlation showed that most of hand-related factors were strongly associated with other body items. Finger breadth and hand depth, however, were found less related to other body items. The ANOVA test used in testing the difference of hand factors showed, in most items, a difference by ages, but there was no significant differences in fingertip breadth, the third factor, Interestingly, in hand depth, the fifth factor, lower grade girls' hands were thicker than higher grade girls'. This research suggests that the size system of uniformly increasing the size of all hand parts by age groups should be reconsidered and leaves much for improvement.

In recent years, many recommendation service systems that search or recommend information automatically considering user's taste or property are developed. However, there is a weak point that correct recommendation is hard without considering the preference of user's context. This paper proposes a filtering method that gives correct recommendation considering the preference of user's context. To support this method, we get UCOP(User-Context Object Preference) using the preference of user's context and Pearson correlation coefficient. The results of the experiment show the improvement of 11%, 2% of precision and 8%, 4% of recall comparing with the existing service systems. Our recommendation service systems show 77% of precision and 53% of recall overall.

Purpose: The purpose of this study was to explore job stress, job satisfaction and their relationship among Workers' Compensation Case Managers. Method: 137 Workers' Compensation Case Managers (89 case workers and 48 nurses) responded to a self-administered questionnaire. The data were collected in october, 2006 and analyzed using t-test and Pearson's Correlation Coefficient with SPSS WIN 14.0 program. Result: The mean score of job stress of nurses was 2.60 which was higher than that of the Korean female workers'. The mean score of job satisfaction was 2.30. The significant inverse correlation between job stress and job satisfaction was found (P<.01). In regard to the 7 items, the significant inverse correlations were found in lack of reward, interpersonal conflict, organizational system, insufficient job control, and occupational environment. Conclusion: The result indicated that the Workers' Compensation Case Managers have higher occupational stress and lower job satisfaction. To improve their job satisfaction, it is necessary to reinforce reward, organizational system, job autonomy, and cooperative occupational environment.
