Purpose: In this study, the relationship between the interpersonal relationships, clinical stress and satisfaction of clinical practice among nursing was examined. Method: The participants were 261. Data collected from 7 September to 18 September 2015 were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Result: The mean scores for the interpersonal relationship ($3.74{\pm}0.39$), stress ($3.21{\pm}0.54$), and satisfaction ($3.44{\pm}0.45$) in clinical practice were above average. Interpersonal relationships differed significantly according to year (F=3.12, p=.046), satisfaction with nursing as a major (F=15.84, p<.001), important of interpersonal relationships (F=4.76, p=.001), and academic achievement (F=3.80, p=.011). Stress in clinical practice differed significantly according to the year (F=8.05, p<.001), application motivation (F=4.55, p=.001) and satisfaction with nursing as a major (F=2.69, p=.046). Satisfaction in clinical practice differed significantly according to satisfaction with nursing as a major (F=3.24, p=.022), important of interpersonal relationships (F=3.01, p=.019), and academic achievements (F=5.24, p=.002). Significant correlations were observed between the interpersonal relationships and satisfaction in clinical practice (r=.24, p<.001). Interpersonal relationship (${\beta}=.21$, p<.001), academic achievements (${\beta}=.12$, p=.045) were factors influencing satisfaction in clinical practice. Conclusion: The interpersonal relationships need to be improved to increase nursing students' satisfaction with clinical practice

For 0 < $p$ < ${\infty}$, ${\alpha}$ > -1 and 0 < $r$ < 1, we show that if $f$ is in the space of Dirichlet type $\mathfrak{D}^p_{p-1}$, then ${\int}_{1}^{0}M_{p}^{p}(r,f^{\prime})(1-r)^{p-1}rdr$ < ${\infty}$ and ${\int}_{1}^{0}M_{(2+{\alpha})p}^{(2+{\alpha})p}(r,f^{\prime})(1-r)^{(2+{\alpha})p+{\alpha}}rdr$ < ${\infty}$ where $M_p(r,f)=\[\frac{1}{2{\pi}}{\int}_{0}^{2{\pi}}{\mid}f(re^{it}){\mid}^pdt\]^{1/p}$. For 1 < $p$ < $q$ < ${\infty}$ and ${\alpha}+1$ < $p$, we show that if there exists some positive constant $c$ such that ${\parallel}f{\parallel}_{L^{q(d{\mu})}}{\leq}c{\parallel}f{\parallel}_{\mathfrak{D}^p_{\alpha}}$ for all $f{\in}\mathfrak{D}^p_{\alpha}$, then ${\parallel}f{\parallel}_{L^{q(d{\mu})}}{\leq}c{\parallel}f{\parallel}_{\mathcal{B}_p(q)}$ where $\mathcal{B}_p(q)$ is the weighted Besov space. We also find the condition of measure ${\mu}$ such that ${\sup}_{a{\in}D}{\int}_D(k_a(z)(1-{\mid}a{\mid}^2)^{(p-a-1)})^{q/p}d{\mu}(z)$ < ${\infty}$.

In this paper, we investigate the [p, q] - φ order and [p, q] - φ type of f₁ + f₁, ${\frac{f_1}{f_2}}$ and f₁ f₁, where f₁ and f₁ are analytic or meromorphic functions with the same [p, q]-φ order and different [p, q]-φ type in the unit disc. Also, we study the [p, q]-φ order and [p, q]-φ type of different f and its derivative. At the end, we investigate the relationship between two different [p, q] - φ convergence exponents of f. We extend some earlier precedent well known results.

Let A(p) be the class of functions $f\;:\;z^p\;+\;\sum\limits_{j=1}^{\infty}a_jz^{p+j}$ analytic in the open unit disc E. Let, for any integer n > -p, $f_{n+p-1}(z)\;=\;z^p+\sum\limits_{j=1}^{\infty}(p+j)^{n+p-1}z^{p+j}$. We define $f_{n+p-1}^{(-1)}(z)$ by using convolution * as $f_{n+p-1}\;*\;f_{n+p-1}^{-1}=\frac{z^p}{(1-z)^{n+p}$. A function p, analytic in E with p(0) = 1, is in the class $P_k(\rho)$ if ${\int}_0^{2\pi}\|\frac{Re\;p(z)-\rho}{p-\rho}\|\;d\theta\;\leq\;k{\pi}$, where $z=re^{i\theta}$, $k\;\geq\;2$ and $0\;{\leq}\;\rho\;{\leq}\;p$. We use the class $P_k(\rho)$ to introduce a new class of multivalent analytic functions and define an integral operator $L_{n+p-1}(f)\;\;=\;f_{n+p-1}^{-1}\;*\;f$ for f(z) belonging to this class. We derive some interesting properties of this generalized integral operator which include inclusion results and radius problems.

Enzymatic activities and fluorescence spectroscopic properties of the double mutant proteins P96L/F139W, P96L/F258W and a triple mutant protein P96L/F139W/F258W of tryptophan synthase $\alpha$ subunit from Escherichia coli was examined to study tertiary and local structure changes around the tryptophan residues. The enzymatic activities of P96l./F139W and P96L/F258W were similar, but P96L/F139W/F258W had lower activity, as compared to wild type. The fluorescence intensities of double mutant, P96L/F139W and P96L/F258W, were decreased but that of a triple mutant, P96L/F139W/F258W, was increased when compared to wild type. The sum of the maximum fluorescence intensity (fluorescence intensity at the λ$_{max}$) for the double mutant proteins was not equal to the intensity seen in the triple mutant protein. The enzymatic activity and fluorescence data indicate that the replacement of Pro$^{96}$ longrightarrowLeu might affect on the stability of helix 8 and the loop located between strand 4 and helix4. The result suggests that the tertiary structure of triple mutant (P96L/F139W/F258W), being different from wild type, might have more compact residual structure at the vicinity of 139 and 258.8.

This experiment was carried out to obtain the information on the crossability, variation of chromosome number in pollen mother cell (PMC) and somatic cell of the progeny from the cross between hexaploid triticale cv. Sinkihomil and two diploid rye varieties. Seed set was 39.3 to 41.6% (averaged 40.5%) in the cross between triticale (P$_1$) and rye(P$_2$), which resulted in 0.33% in F$_2$(selfed F$_1$), 2.69% in F$_1$/P$_1$ 5.47% in F$_1$/P$_2$ respectively. However, seed set was extremely low in both reciprocal crosses when triticale was used as male. Germination rate of the crossed seed was 94.0% in F$_1$ 40.8% in F$_2$(selfed F$_1$), 59.5% in F$_1$/P$_1$ and 65.9% in F$_1$/P$_2$ from the cross between triticale and rye, respectively. Pollen fertility of F$_1$ plant was averaged 18.7% in the cross between triticale and rye. Number of Uni-, Bi-, and Trivalent in PMC was 12. 6, 6.94, and 0.53, respectively, in the F$_1$ between the triticale and rye. There were 28 chromosomes in F$_1$, 21 to 34 in F$_2$, 34 to 38 in F$_1$/P$_1$ and 19 to 23 in F$_1$/P$_2$ from the cross between the triticale and rye, respectively.

Asthma is a chronic and allergic inflammation in the lung, mainly caused by house dust mites (HDM). Recent studies have reported Der p 38 and Der f 38 (Dermatophagoides pteronyssinus and D. farinae, respectively) as crucial allergens of HDMs. This study investigates the different allergic effects of Der p 38 and Der f 38 in an asthma-like mouse model. Lung infiltration of neutrophils was induced by intranasal administration of Der p 38 and Der f 38, with stronger infiltration being observed after exposure to Der p 38. Intranasal and intraperitoneal administration of Der p 38 induced the infiltration of neutrophils and eosinophils in the lung, which was similar to the effect subsequent to Der f 38 administration. Although the number of mast cells was increased, no significant difference was obtained between the effects of both allergens. In TLR4 knockout BALB/c mice, Der p 38 and Der f 38 had no effect on the infiltration of neutrophils, eosinophils, and mast cells. Additionally, allergenicity induced by Der p 38 and Der f 38 in the basophils of Der p38+/Der f 38+ asthmatic subjects was similar, although Der f 38 presented stronger allergenicity in basophils of Der p38+/Der f 38+ allergic patients than Der p 38. These findings contribute to understanding the role of similar allergen components derived from different species in the pathogenesis of allergic diseases.
