Model - Free Interval Prediction in a Class of Time Series with Varying Coefficients
Sang Woo Park,Sin Sup Cho,Sang Yeol Lee,Sun Y . Hwang 한국데이터정보과학회 2000 한국데이터정보과학회지 Vol.11 No.2
Interval prediction based on the empirical distribution function for the class of time series with time varying coefficients is discussed. To this end, strong mixing property of the model is shown and results due to Fotopoulos et. al.(1994) are employed. A simulation study is presented to assess the accuracy of the proposed interval predictor.

<P>Adoptive cytotoxic T lymphocyte (CTL) therapy has an important implication in treating cancer patients. Here, we investigate whether adoptive transfer of human papillomavirus (HPV) E7-specific CTL can enhance tumor chemoresponse using an established cervical cancer animal model. Cisplatin-based chemotherapy plus CTL therapy showed an improved therapeutic effectiveness, along with antitumor protective responses to a parental tumor cell rechallenge. Cisplatin treatment dose-dependently increased the expression of Fas, intercellular adhesion molecule (ICAM)-1, and major histocompatibility complex (MHC) class I antigens (Ags) on tumor cells in vitro. However, CTL-expressing FasL failed to improve antitumor activity in vitro and in animals, resulting from nonfunctional Fas expressed on tumor cells. In contrast, ethylene glycol tetraacetic acid (EGTA) treatment blocked increased sensitivity of cisplatin-treated tumor cells to CTL-mediated killing in vitro, suggesting an important role of the perforin/granzyme-mediated pathway for improved therapeutic effectiveness. This notion was further confirmed by perforin knockout animal studies. Thus, this study shows that (i) modulation of Ag (Fas, ICAM-1) expression by tumor cells has little effect on their increased sensitivity to CTL-mediated killing, (ii) improved therapeutic effectiveness is mediated mainly through the perforin/granzyme-mediated tumor killing pathway, and (iii) a combination of chemotherapy and adoptive E7-specific CTL transfer augments antitumor therapeutic activity in vivo. This finding may have important implications for treating HPV-associated cervical cancer.</P>

Surgical removal of impacted mandibular third molars frequently require tooth sectioning or bone removal. In this study, 361 mesioangular or horizontal impacted mandibular third molars are removed surgically by tooth section, the methods of tooth section are classified as 4 stages and 12 grades in the number of times and technics of crown or roots section and difficulties. Grades and their cases are followings: 1. occlusal crown first section(100, 28%) 2. distal crown first section(69, 19%) 3. occlusal crown second section(29, 8%) 4. distal crown second section(52, 14%) 5. occlusal crown first section and root section(10, 3%) 6. distal crown first section and root section(27, 7%) 7. occlusal crown third section(3, 1%) 8. distal crown third section(22, 6%) 9. occlusal crown second section and root section(13, 3%) 10. distal crown second section and root section(17, 5%) 11. occlusal crown third section and root section(2, 1%) 12. distal crown third section and root section(17, 5%)

The asymptotic distribution of residual autocorrelation functions from a generalized p-order random coefficient autoregressive process (GRCA(p)) is derived. To this end, we first describe the GRCA(p) models and then consider the normalised residuals after fitting the model. This result can be applied to the residual analysis for the diagonostic purpose.
