The purpose of this study was to determine the relationships among the functional status, hostility, and social support in patients with percutaneous coronary intervention (PCI). The subjects were comprised of 135 patients who had received PCI from two general hospitals in Seoul, Korea. The functional status differed significantly according to gender (t=5.880, p<0.001), age (F=23.620, p<0.001), education (F=17.718, p<0.001), occupation (t=-6.498, p<0.001), monthly income (F=7.237, p<0.001), and smoking (t=2.327, p=0.025). The hostility differed significantly according to age (F=6.150, p=0.001), period after PCI (F=6.141, p=0.001), and family history (t=2.514, p=0.013). Differences were observed in the scores for social support according to age (F=2.866, p=0.039) and education (F=5.136, p=0.002). Significant positive correlations were found among functional status and social support (r=.20, p=0.025), friends support (r=.22, p=0.010) and a significant negative correlation between functional status and hostility (r=-.24, p=0.005). A significant negative correlation was found between hostility and friends support (r=-.17, p=0.046). Nurses should consider the characteristics of patients who have undergone PCI and develop nursing intervention programs to improve their functional status, hostility, and social support.

The purpose of this study was to investigate the somatic symptoms, trait anger, and anger expression styles perceived by cancer patients, examine their relationships, and identify variables influencing somatic symptoms. The mean of patients' somatic symptoms was 8.59 ± 5.34, trait anger was 1.78±0.53, and anger suppression was 2.02±0.36, which is the highest. In terms of differences in somatic symptoms according to the general characteristics of the subjects, stage 3 cancer stage was the highest compared to other stages(F=2.745, p=.045), and the presence of cancer-related pain was significantly higher compared to its absence(t=5.046, p<.001). Differences in trait anger according to the general characteristics of the patients were found to be significant based on monthly income(F=3.952, p=.004). Differences in anger expression styles were found by age(F=4.186, p=.017), monthly income(F=3.302, p=.012), and experience of cancer-related pain(t=2.715, p=.007) in anger suppression, while differences were observed by age(F=3.637, p=.028), employment status(t=2.563, p=.011), monthly income(F=3.580, p=.008), and duration of treatment(F=3.726, p=.026) in anger regulation. The somatic symptoms perceived by the patients had positive correlations with trait anger(r=.209, p=.006), anger suppression(r=.206, p=.006), anger expression(r=.199, p=.008), and anger regulation(r=.194, p=.009). It was found that a greater presence of cancer-related pain was related with a higher level of somatic symptoms of patients among other variables.

The geometries and isomerization of the alkylidene silylenoid $H_2C$ = SiLiF as well as its insertion reactions with R-H (R = F, OH, $NH_2$) have been systematically investigated at the B3LYP/6-311+$G^*$ level of theory. The potential barriers of the three insertion reactions are 97.5, 103.3, and 126.1 kJ/mol, respectively. Here, all the mechanisms of the three reactions are identical to each other, i.e., an intermediate has been formed first during the insertion reaction. Then, the intermediate could dissociate into the substituted silylene ($H_2C$ = SiHR) and LiF with a barrier corresponding to their respective dissociation energies. Correspondingly, the reaction energies for the three reactions are -36.4, -24.3, and 3.7 kJ/mol, respectively. Compared with the insertion reaction of $H_2C$ = Si: and R-H (R = F, OH and $NH_2$), the introduction of LiF makes the insertion reaction occur more easily. Furthermore, the effects of halogen (F, Cl, Br) substitution and inorganic salts employed on the reaction activity have also been discussed. As a result, the relative reactivity among the three insertion reactions should be as follows: H-F > H-OH > H-$NH_2$.

Forty eight fungal isolates were isolated from the maeius collected through the whole nation. Out of them, nine isolate were observed to be zygomyceteous fungi(4 genera and 9 species): Mucor hiemalis, M. circinelloides f. griseo-cyanus, M. circinelloides, M. jansseni, M. racemosus f. racemosus, Mortierella isabellina, Rhizopus stolonifer, R. oryzae, and Absidia corymbifera. Four species(M. circinelloides f. griseo-cyanus, M. hiemalis, M. jansseni, and R. oryzae) identified here were known as species involved in maeiu but not described in detail. The others were first reported as a species inhabiting in the maeiu. Two species of M. hiemalis f. hiemalis. and M. circinelloides f. griseo-cyanus were determined to play a role in biochemical changes of soybean in the fermentation of maeiu. However, the others seldom inhabited but considered to be comtaminated fungi in maeiu.

Reynoutria japonica and R. sachalinensis have been used as medicinal resources in Korea. However, it is difficult to identify and determine these medicinal herbs correctly because they are usually customized and purchased as the fragmented rhizomes types. To develop molecular markers for distinguishing two species, we analyzed and compared the chloroplast DNA sequences of seven loci (atpB, matK, ccD-psaI, atpF-H, trnL-trnF, psbK-I and rpl32-trnL). Among them, we found two effective SNPs in psbK-I region for R. japonica and atpF-H region for R. sachalinensis. Based on these SNP sites, we designed the new R. japonica- specific primer which is able to amplify 300 bp fragment in psbK-I region. A similar strategy was applied for the atpF-H region of R. sachalinensis. These molecular markers would be successfully applied to recognize R. japonica and R. sachalinensis.

We say that an isometric immersed hypersurface x : $M^n\;{\rightarrow}\;{\mathbb{R}}^{n+1}$ is of $L_k$-finite type ($L_k$-f.t.) if $x\;=\;{\sum}^p_{i=0}x_i$ for some positive integer p < $\infty$, $x_i$ : $M{\rightarrow}{\mathbb{R}}^{n+1}$ is smooth and $L_kx_i={\lambda}_ix_i$, ${\lambda}_i\;{\in}\;{\mathbb{R}}$, $0{\leq}i{\leq}p$, $L_kf=trP_k\;{\circ}\;{\nabla}^2f$ for $f\;{\in}\'C^{\infty}(M)$, where $P_k$ is the kth Newton transformation, ${\nabla}^2f$ is the Hessian of f, $L_kx\;=\;(L_kx^1,\;{\ldots},\;L_kx^{n+1})$, $x=(x^1,\;{\ldots},\;x^{n+1})$. In this article we study the following(hyper)surfaces in ${\mathbb{R}}^{n+1}$ from the view point of $L_1$-finiteness type: totally umbilic ones, generalized cylinders $S^m(r){\times}{\mathbb{R}}^{n-m}$, ruled surfaces in ${\mathbb{R}}^{n+1}$ and some revolution surfaces in ${\mathbb{R}}^3$.

Let (${\Omega}$, $\mathcal{S}$, ${\mu}$) be a probabilistic measure space, ${\varepsilon}{\in}\mathbb{R}$, ${\delta}{\geq}0$, p > 0 be given numbers and let $P{\subset}\mathbb{R}$ be an open interval. We consider a class of functions $f:P{\rightarrow}\mathbb{R}$, satisfying the inequality $$f(EX){\leq}E(f{\circ}X)+{\varepsilon}E({\mid}X-EX{\mid}^p)+{\delta}$$ for each $\mathcal{S}$-measurable simple function $X:{\Omega}{\rightarrow}P$. We show that if additionally the set of values of ${\mu}$ is equal to [0, 1] then $f:P{\rightarrow}\mathbb{R}$ satisfies the above condition if and only if $$f(tx+(1-t)y){\leq}tf(x)+(1-t)f(y)+{\varepsilon}[(1-t)^pt+t^p(1-t)]{\mid}x-y{\mid}^p+{\delta}$$ for $x,y{\in}P$, $t{\in}[0,1]$. We also prove some basic properties of such functions, e.g. the existence of subdifferentials, Hermite-Hadamard inequality.
