Prepositional stranding (P-Stranding), which was possible only in certain types of constructions in Old English, began to be allowed more freely in the Middle English (ME) period, resulting in many new types of P-Stranding. Although many relevant studies have tried to account for the development of these new P-Stranding types, none of them or no combination of them seem to adequately explain how the new types came into being in ME and why they occurred in the order in which they occurred. In this paper, I explain why the development of new P-Stranding types in Middle English cannot be properly explained by any of the previous studies and then provide an alternative account of the advent of each new type of P-Stranding and the chronology involved on the basis of the displacement of the prepositional object from PP (DPO), a constraint on DPO (DPO), and the subject requirement (SubjR).

The effects of additional P-doping on the magnetic properties, thermal stability and cation distribution of Co-doped ${\gamma}-{Fe_2} {O_3}$have been investigated by means of magnetic annealing and measurements with vibration sample magnetometer and torque magnetometer. It is found that the P-doping promotes the coercivity and its magnetic-thermal stability, which may be attributed to increase of the cubic magneto-crystalline anisotropy constant, $K_1$ and the activation energy, E, for cation rearrangement, respectively. The cation distribution of P and Co-substituted iron oxide was calculated from the variation of the saturation magnetization with P-doping on the basis of the Neel model. It was found that the most of P ions in the iron oxides occupied the B-site of spinel lattice.

The p-version crack model based on integrals of Legendre polynomial and virtual crack extension method is proposed with its potential for application to stress intensity factor computations in linear elastic fracture mechanics. The main advantage of this model is that the data preparation effort is minimal because only a small number of elements are used and the high accuracy and the rapid rate of convergence can be achieved in the vicinity of crack tip. There are two important findings from this study. Firstly, the limit value, the strain energy of the exact solution can be estimated with successive three p-version approximations by ascertaining the approximations is entered the asymptotic range. Secondly, the rate of convergence of p-version model is almost twice that of h-version model on the basis of uniform or quasiuniform mesh refinement for the cracked panel problem subjected tension.

A general stiffener element which includes transverse shear deformation(TSD) is formulated using the p-version of finite element method. Hierarchic C"-shape functions, derived from Integrals of Legendre polynomials, are used to define the assembled stiffness matrix of the stiffener and plate on the basis of 5 D.0.F displacement fields. The stiffness matrix for the stiffener with respect to the local reference frame is transformed to the plate reference system by applying the appropriate transformation matrices in order to insure compatibility of displacements at the junction of the stiffener and plate. The transformation matrices which account for the orientation and the eccentricity effects of the stiffener with respect to the plate reference axes are used to find local behavior at the junction of the stiffener and the relative contributions of the plate and stiffener to the strength of the composite system. The results obtained by the p-version of the finite element method are compared with the results in literatures, especially those by the h-version software, MICROFEAP-II.P-II.

The rate constants of hydrolysis of ${\alpha}$, N-diphenylnitrone and its derivatives have been determined by UV spectrophotometry from pH 2.0 to 13.5, and a rate equation which can be applied over a wide pH range was obtained. On the basis of rate equation, hydrolysis product, and general base and substituent effects, a plausible mechanism of hydrolysis has been proposed: Below pH 5, the hydrolysis was initiated by the protonation and followed by the addition of water to ${\alpha}$-carbon. However, above pH 11, the hydrolysis was proceeded by the addition of hydroxide ion to ${\alpha}$-carbon. In the range of pH 5-11, the addition of water to nitrone is rate controlling step.

The purpose of this study was to compare the differences of attitude to death and perception on HPC between nursing and medical students. The data was collected by questionnaires and the period of data collection was from September 17 to October 12, 2012. The results were as followings. Statistically significant differences were found course of knowing HPC(${\chi}^2$=24.29, p<.001), reason of unactive introduction(${\chi}^2$=15.92, p=.003), having to CPR in irresponsive terminal situation to you(${\chi}^2$=4.62, p=.032) and to your family(${\chi}^2$=5.64, p=.018), decision-making about DNR(${\chi}^2$=12.28, p=.002), awareness to medical authority legal representative(${\chi}^2$=14.75, p<.001), awareness (${\chi}^2$=11.01, p=.001) and subject(${\chi}^2$=24.73, p<.001) of AD, addiction(p<.001), tolerance(p<.001), taking a point(${\chi}^2$=23.28, p<.001) of narcotic analgesics and control of pain(p=.532). The findings of the study provides the basis for expanding practice and education to hospice-palliative care for nursing and medical students.

The pharmacokinetics of orally administered paclitlxel (50 mg/kg) was studied in six rabbits after 1hr pretreatment (2.0 mg/kg and 10 mg/kg) of tetramethoxyflavone or coadministration of (2.0 mg/kg, 10 mg/kg and 20 mg/kg) tetramethoxyflavone. The area under the plasma concentration-tine curve (AUC) and plasma concentration of paclitaxe1 coadministered with tetramethoxyflavone (10 mglkg) were increased significantly (p<0.05) compared with control. However, coadministration of tetramethoxyflavone (2 and 20 mg/kg) showed no significant effect on the pharmacokinetic parameters of paclitaxel. Pretreatment with tetramethoxyflavone significantly (p<0.05) increased the plasma concentration of paclitaxel. The area under the plasma concentration-time curve (AUC) and the peak concentration (C$_{max}$) of paclitaxel pretreated with tetramethoxyflavone were increased significantly (p<0.01, p<0.05) compared with control. The terminal half. life of paclitaxel pretreated with tetramethoxyflavone (2 mg/kg and 10 mg/kg) was significantly (p<0.05) prolonged compared with control. Pretreatment with tetramethoxyflavone (2.0 mg/kg, 10 mg/kg) significantly (p<0.01, p<0.05) increased the absolute bioavailability of paclitaxel compared with the control (154∼179%). On the basis of the results, it might be considered that tetramethoxyflavone may inhibit cytochrome P450 or P-glycoprotein efflux pump which are engaged in paclitaxel metabolism, result in increased AUC and t$_{1}$2/ of paclitaxel. However, further study should be conducted to clarify the roles of cytochrome P450 and P-glycoprotein on paclitaxel bioavailability with/or without tetramethoxyflavone. P-glycoprotein on paclitaxel bioavailability with/or without tetramethoxyflavone.

Two species of Phytophthora were isolated from infected fruits of jujube. Among 18 isolates collected, 6 were identified as P. nicotianae and 12 as P. patmivora on the basis of their mycological characteristics. The former produced no caduceus, ovoid to spherical sporangia in contrast to caduceus, ellipsoid, and broadly avoid to spherical ones of the latter. These two species were shown to be heterothallic and markedly papilate, chlamydospores abundant, and Al mating type. They skewed strong pathogenicity to fruits of jujube and pear while no symptom was produced on apple fruit by artificial inoculation. This is the first report of juiube fruit rot caused by P. ninotianae and P. palmivora in Korea.

In this paper, we introduce metrics d, p and ${\mu}$ on a normed almost linear space (X, III.III). And we prove that above three metrics are equivalent if a normed almost linear space X has a basis and splits as X = W$_X$ + V$_X$.
