Wood and bark structure of Laurus, which is considered as an important spice resources was characterized by several transitional and advanced features. Annual rings are distinct: vessel elements are moderately short and narrow, both simple and sealariform perforation plates. alternate intervascular pitting; irregularly septate fiber are present; parenchyma strands are scanty paratracheal: rays are both homogeneous and heterogeneous with multiseriate: phloem rays are dilated. Comparisons with other genera of Lauraceae suggest that Laurus is transitional and advanced state in evolutionary trends in the family.

The transitional zone between tunnel and earthwork is one of the most vulnerable areas site for railway lines and because of differential settlement due to different stiffness of each supporting layer, it has to conducted a maintenance work constantly. In this study, it is conducted to compare the effect of reinforcement by wheel load and displacement of the sleepers after existing sleepers are replaced with the large sleepers for 20m long in-field transitional zone. Also, numerical parametric study using multi-layer elastic method has been performed to compare rail force, settlement and stresses of ballast while varying size and space of the sleeper. The field test and numerical results show that replacing the large sleepers improves about 10% of total settlement and coefficient of wheel force than conventional sleepers. Effectiveness of improvement is about 9.3%, 4%, 14.5% for rail seat force, settlement of sleepers and ballast pressure respectively with size of sleepers.

Purpose: The purpose of this study was to evaluate the effects of Doula support during labor on anxiety, labor pain, and perceived childbirth experience of primiparas. Method: Of 65 primiparas who were hospitalized in LDR from March 1 to September 30, 2007. 32 women were placed in the Doula group and 33 in the control group. VAS was used to measure the degree of labor pain and anxiety in the latent, active, and transitional phases. Perceived childbirth experience was measured within 2 hours after birth. Results: The Doula group had a significantly lower anxiety level than the control group in the active phase (t=-2.13, p=.04) and the transitional phase (t=-3.99, p=.000). The degree of labor pain of the Doula group was significantly lower than that of the control group for the active phase (t=-3.10, p=.003) and the transitional phase (t=-7.24, p=.000). Also, There was no significant difference in perceived childbirth experience between the two groups (t=.19, p=.85). Conclusion: The results of this study show Doula support in LDR decreases not only anxiety of primiparas but also labor pain in the active and transitional phases. Therefore Doula support by nurses in LDR can be a useful intervention during childbirth.

In this study, numerical simulations were performed using the ${\gamma}-Re_{\theta}$ transition model of KFLOW for the transitional flow over the KARI-11-180 airfoil. Numerical results of KFLOW were compared with experimental data and two other numerical results of XFoil and MSES. Fully turbulence model was predicted high skin friction drag than transition model because fully turbulence model could not solve the transitional flow. Numerical predictions using the ${\gamma}-Re_{\theta}$ model of KFLOW show a good agreement with experimental data and other numerical results. Present numerical results were confirmed the state of drag bucket due to dramatic changing of the transition location on the airfoil surface.

Objectives: The purpose of this study was to determine the relationship between methylation status of the Dact1 gene and MTHFR a1298c polymorphic forms in transitional cell carcinoma tissues in a Chinese population. Methods: Polymorphisms of folate metabolism enzyme gene MTHFR were assessed by restrictive fragment length polymorphism (RFLP) methods and PCR-based DNA methylation analysis was used to determine the CpG island methylation status of the Dact1 gene. Associations between the methylation status of the Dact1 gene and clinical characteristics, as well as MTHFR a1298c polymorphisms, were analyzed. Results: aberrant methylation of the Dact1 gene was found in 68.3% of cancer tissues and 12.4% of normal tissues,. The methylation rate of the Dact1 gene in cancer tissues was significantly higher in patients with lymph node metastasis than in those without lymph node metastasis (46.3% vs. 17.2%, P = 0.018). No association was found between aberrant DNA methylation and selected factors including sex, age, tobacco smoking, alcohol consumption and green tea consumption. After adjusting for potential confounding variables, variant allele of MTHFR a1298c was found to be associated with methylation of the Dact1 gene. Compared with wild type CC, the odds ratio was 4.33 (95% CI: 1.06-10.59) for AC and 4.95 (95% CI: 1.18-12.74) for AA. The N stage in TNM staging and the occurrence of lymph node metastasis were associated with an MTHFR 1298 AA+AC genotype (P<0.05). Conclusion: MTHFR 1298 AC and AA genotypes might help maintain a normal methylation status of the Dact1 gene, aberrant CpG island methylation of which is closely related to the genesis and progression of transitional cell carcinoma.

The youth with developmental disorders have substantial limitations in intellectual capacities and adaptive behaviors. For them to live independently as members of the local society after they graduate from high school, a continuous education in consideration of individual and environmental differences should be accompanied. The computer education can be a useful tool in their integration into the local society by 'Expansion of universality and the equality of education'. Particularly, the computer education as a transitional educational process can be of practical help for them to sustain independent and daily lives in the adult world. In this regard, this writing reviews 1) the integration into the local society of the youth with developmental disorders and the transitional education, 2) the significance and meaning of computer education for the youth with developmental disorders, and 3) the status of computer education for the youth with developmental disorders to present improvements for the computer education of the youth with development disorders.

A four-year-old spayed female Maltese dog weighing 3 kg was referred with reverse sneezing and fourmonth history of unilateral nasal discharge. She was diagnosed as nasal transitional carcinoma which in bilateral nasal cavity and extending into the frontal sinus by biopsy with rhinoscopy. Metronomic chemotherapy with cyclophosphamide ($12.5mg/m^2$) and toceranib phosphate (2.5 mg/kg) was initiated following after surgical treatment of nasal mass debulking. Clinical response was good and had no side effects during the chemotherapy period (11 months after diagnosis). This is a case report describing adjuvant metronomic chemotherapy in nasal transitional carcinoma in Korea.

Purpose: Recently, dental implant systems have been widely used for the treatment of the extraction site, but we have been confronted with many limitations in esthetics, phonetics and function. Transitional implants(TI) were developed as a method of providing fixed provisional restorations during conventional implant healing. Until now, little data have been provided on korean transitional implants. The purpose of this study is to evaluate the implant placement site histologically after 4 weeks and 8 weeks. Materials and Methods : Test group( IntermetzzoTM MEGAGEN, KOREA) and control group(Mini Drive Lock, Intra Rock, U.S.A.) were immediately placed in interseptal or interproximal bone of beagle dog after mandibular premolars extraction, and had a healing period with non-submerged state but without loading, Both TI surfaces were composed of rough surfaces. Results: In the test group, the average percentage of BIC were respectively 39.40%(SD7.35) after 4 weeks and 44.05%(16.76) after 8 weeks, and In the control group were 50.75%(1.48) and 59.40%(0.00). Discussion: We evaluated the initial ability of the osseointegration of TI through this study. Because TI is placed with a conventional implant simultaneously and loaded immediately, the ability of osseointegration is a very important factor for the success of TI during the initial healing phase. Conclusion: The results of the histological evaluation of these two groups were similar to those mentioned in other studies for osseointegration of implant.
