The present study has been performed to revise the forms of early-onset periodontitis(EOP) into the homogeneous phenotypic subsets by cluster analysis using sets of clinical parameters. Retrospective radiographic interproximal alveolar bone levels were measured from cemento-enamel junctions on patients who have previously been diagnosed as having one of EOP during last 5 years. Mean interproximal bone levels(BL) and mesial bone level(Ratio) of 1st molars relative to mean interproximal bone levels of adjacent teeth(lst and 2nd premolars and canines)were calculated on each patient. Using parameters BL and Ratio(BR group) or BL, Ratio and age(BRA group), cluster analysis was performed to revise EOP patients into homogeneous subsets. At least three or four cluster could be homogeneously formed both in BR or BRA groups with statistically significant differences in parameters used among clusters as evidenced by MANOVA test. It was shown that the greater the BL, the smaller the Ratio was. It was also evident that mean interproximal bone levels were lowest aroud 1st molars and/or incisors regardless of cluster types. The results has provided cluster-based studies for identifying laboratory markers responsible for the development of EOP subsets.

PURPOSE: We investigated the relationship between personality, music type and MVIC, power for the knee extensor on inducing muscle fatigue. METHODS: The subjects of this study were 22 healthy students. MVIC(Maximum Voluntary Isometric Contraction) and power in knee extension was measured by PRIMUS RS. Personality types was measured by MBTI(Myers-Briggs Type Indicator) that is an instrument designed to provide descriptive profiles of personality types and preferences. The collected data were analyzed using the independent t-test, MANOVA and Pearson-test. RESULTS: There was no significant differences both MVIC and power of the knee extensor according to personality and music type. The power was significantly increased by increasing the MVIC during a knee extension on inducing muscle fatigue without music type(r= .786~.896). There was no significant correlation both MVIC and power of the knee extensor according to personality. CONCLUSION: There was a positive correlation between power and MVIC during a knee extension on inducing muscle fatigue without music type. There was no significant correlation both MVIC and power of the knee extensor according to personality.

This paper investigates the relationship of service quality and user satisfaction in the wired and mobile Internet services based on the integrative framework of both systems. Given a moderate level of reliability and validity, the commonly driven dimensions for measuring service quality include responsiveness, assurance, empathy, convenience, usefulness, and diversity. User satisfaction is measurable by the dimensions of communication/entertainment, finance/economics, location/geography, and information/consulting. We apply the MANOVA tests to evaluate whether each of the service quality dimensions has an overall influence on user satisfaction. Next, multiple regression analyses are conducted to check if unique positive effect exists between each combination of service quality dimensions and user satisfaction dimensions. The results show that service quality must be taken care of with respect to the assurance dimension in order to enhance customer satisfaction in the dimensions of location/geography, which will contribute to increasing the utilization of mobile service. For improving user satisfaction in the dimension of information/consulting, service quality must be supported with respect to assurance and empathy in the mobile Internet market, in addition to diversity, which is the only significant service quality in the wired Internet service.
