This study examined the effects of growth factors in TCM199 on bovine 1-cell embryos development in vitro. After 6 day to 11 day in culture, 15.8%(19/120), 15.3%(20/130), 21.8%(35/160), 27.0%(56/207), 26.3%(53/201) and 30.7%(40/130) of the 1-cell embryos developed into expanding blastocysts in su, pp.ementing TCM199 with control, insulin, IGF-I, IGF-II, FGF and EGF, respectively. Hatching rate of 1-cell embryos in su, pp.ementing TCM199 with FGF, EGF and IGF-II were 21.4%(53/247), 20.3%(42/206) and 16.8%(41/243), respectively. The beneficial effect of growth factors on embryo development in vitro could be duplicated. These data indicate that the presence of FGF, EGF or IGF-II in the culture medium is beneficial for embryo development in vitro and accelerate cell differentiation.

Interleukin-4(IL-4) is known to be a major cytokine regulating immunoglobulin E(IgE) response by the induction of IgE production and type II IgE receptor(IgER II: CD23) expression. Recently, however, the role of neuroendocrine factors has been implicated in modulating the IgE response. Among various neuroendocrine growth factors, we investigated the effects of the insulin-like growth factor-1(IGF-1) since IL-4 and IGF-1 share common intracellular signaling molecules, such as the insulin receptor substrate-1/2(IRS-1/2) to induce a specific cellular response. In the human peripheral blood mononuclear cell (PBMC) cultures, IGF-1 was capable of inducing a substantial level of IgE production in a dose-dependent manner. It also noticeably upregulated the IL-4-induced or IL-4 plus anti-CD40-induced IgE production. Similarly, the IGF-1-induced IgE production was enhanced by IL-4 or anti-CD40 in an additive manner, which became saturated at high concentrations of IGF-1. Although IGF-1 alone did not induce IgER II (CD23) expression, it augmented the IL-4-induced surface CD23 expression in a manner similar to the action of anti-CD40. These results imply that IGF-1 is likely to utilize common signaling pathways with IL-4 and anti-CD40 to induce IgE and IgER II expression. In support of this notion, we observed that IGF-1 enhanced the IL-4-induced signal transducers and activators of transcription 6(STAT6) activation and independently induced $NF-{\kappa}B$ activation. Both of these bind to the IgE(C) or IgER II (CD23) promoters. Together, our data suggest that IL-4 and IGF-1 work cooperatively to activate STAT6 and $NF-{\kappa}B$. This leads to the subsequent binding of these transcription factors to the $C{\varepsilon}$ and CD23 promoters to enhance the expression of IgE and IgER II. The observed differential ability of IGF-1 on the induction of IgE vs. IgER II is discussed based on the different structure of the two promoters.

Purpose: This study was performed to identify factors affecting the functional status in disabled persons in the Jeiu Province. Method: Data were collected from 318 disabled persons in the Jeiu province during the period from the 6th of July to the 11th of October in 2006. The functional status was assessed by the disability assessment schedule II (Whodas II) of the World Health Organization and collected data were analyzed using the SAS 8.0 program. Result: The mean score of WHODAS II was 29.9. According to the results of multiple regression, factors affecting the functional status were perceived health condition(t=3.44, p<.001), brain disorder disability(t=2.55, p<.001), treatment status(t=-1.95, p=.05), drinking(t=2.09, p=.04), stress(t=-2.72, p=.01), depression(t=-2.70, p=.01). heart disease(t=2.62. p=.01) and anemia(t=2.20, p=.03). Conclusion: The functional status was affected by health behaviors, diseases, and the type of disability. Thus, future efforts to promote the functional status of disabled persons may need to take into account all these factors.

Objectives: Human papillomavirus (HPV) infection is highly associated with cervical cancer. So, the modification of the risk factors of HPV infection is essential for prevention of cervical cancer. This study was performed to evaluate the risk factors of HPV infection. Methods: HPV test of 12,337 study population conducted using Hybrid-Capture II assay(HC-II) and self-administered questionnaires were collected. The study population was people who visited hospital-based medical screening center from January to December 2007 and all were female employees or employees' partner. Results: In logistic regression analysis, smoking and alcohol drinking were significant factors, with odds ratios of 1.328 (95% CI 1.010~1.746) and 1.644 (95% CI 1.309~2.066), respectively. Nutritional supplements was also significant factor, which odds ratio was 1.161 (95% CI 1.004~1.343). Oral contraceptives was positive association with HPV infection (odds ratio 2.108; 95% CI 1.217~3.652), whereas condom was negative association (odds ratio 0.851; 95% CI 0.740~0.979). Conclusion: HPV Prevalence of 12,377 study population was 11.4%. Smoking, alcohol drinking, nutritional supplements and oral contraceptives were possible risk factors of HPV infection, and condom had possible preventive effect on HPV infection. Further prospective and comprehensive studies about HPV risk factors are required.

This study attempts to measure body sizes and somatotypes of 844 female middle and high students girls in their growth period and to investigate characteristics of each of the measured somatotypes. The data used for this study were 50 items of body sizes obtained from anthropometric measurements. The purposes of the study are as follows: 1. to analyze physical characteristics according to age. 2. to extract factors of somatotypes using factor analyses. 3. to classify somatotypes according to physical characteristics using cluster analyses. The study results were as follows: 1. TH anthropometric measurements indicated that three existed collective patterns of somatotypes across Group I(12∼13 years old), Group II(14∼15 years old), and Group III(16∼18 years old). 2. Through factor analyses, 6 factors were yielded from each age group. The cumulative proportions of these factors were 77% for Group I, 75% for Group II, and 72% for Group III. Factor I indicates a horizontal size factor and Factor 2 indicates a vertical size factor. 3. Group I and Group II ere classified into 5 types and Group III was classified as 3 types. In Group I, middle height and a little slim types were most prevalent(28%). In Group II, low height and very slim types were most prevalent(28.9%). Finally, In Group III, low height and slim types were most prevalent(4.6%)

Cracking at low temperatures is one of the frequently observed modes of failure in asphalt concretes. In this investigation, fracture tests were performed on cracked asphalt concrete subjected to pure mode I and pure mode II loading at different subzero temperatures. An improved semi-circular bend (SCB) specimen containing a vertical crack was used to conduct the experiments. The SCB specimens produced from the gyratory compacted cylindrical samples were compressively loaded, and critical stress intensity factors, $K_{If}$ and $K_{IIf}$, were then calculated using peak loads obtained from the tests. The experimental results showed that with decreasing the temperature, mode I and mode II critical stress intensity factors increased first but below a certain temperature they both decreased. It was also found that at a fixed temperature, the mode II fracture resistance of the asphalt concrete was higher than its mode I fracture resistance.

Some mixed mode fracture criterion may be converted in to elliptical or ellipsoidal formula with the aid of mathematical translation. Hence, the crack initiation in mixed mode fracture I+II emanating from notches, has been studied using notched circular ring specimens. On the basis of Irwin (1957) theory, a new criteria in mixed mode fracture I+II, based fracture elliptic criterion and notch stress intensity factors has been developed.

Connes [2] showed that if M is an injective .sigma.-finite factor of type II $I_{1}$ and $B_{\phi}$=C1 for some normal faithful state .phi. on M then M is isomorphic to the Araki-wood factor. In [7], Haagerup has succeeded to show that if M is an injective factor of type II $I_{1}$ with separable predual, then $B_{\phi}$=C1 for every normal faithful state on M. Since injective factors of type II $I_{\lambda}$, 0.leq..lambda.<1, were classified [9], this together classifies all injective factors of type III with separable predual. It is not known for non-injective case. In this paper we consider some conditions under which the bicentralizers be trivial.ivial.
