The aim of this study was to investigate the relationship among the variables and the influence of academic self-efficacy and critical thinking disposition on the problem solving ability of nursing students. A descriptive research design was employed in this study. The participants were 404 sophomore nursing students in D city, who were surveyed between May 2 and May 20, 2016, using self-report questionnaire. The data were analyzed with SPSS WIN 21.0 using descriptive statistics, ANOVA, t-test, Scheffe test, Pearson's correlation coefficient, and multiple stepwise regression analysis. Significant correlations among the academic self-efficacy, critical thinking disposition, and problem solving ability were found. In academic self-efficacy and critical thinking disposition, there were significant differences in gender, academic credit, interpersonal relationship, and satisfaction with nursing as a major. The problem solving ability showed statistically significant differences in academic credit, interpersonal relationships, and satisfaction with nursing as a major. The regression model explained 51.7% of the effect on the problem solving ability. Academic self-efficacy and critical thinking disposition were factors influencing the problem solving ability of nursing students. Based on these results, to increase problem solving ability of nursing students, it will be necessary to develop an educational program and strategy for improving the academic self-efficacy and critical thinking disposition.

Let $X_i,...,X_n$ be a random sample from a distribution with cumulants $K_1, K_2,...$. The statistic $t = \frac{\sqrt{x}(\bar{X}-K_1)}{S}$ has the well-known 'student' distribution with $\nu = n-1$ degrees of freedom if the $X_i$ are normally distributed (i.e., $K_i = 0$ for $i \geq 3$). An Edgeworth series expansion for the distribution of t when the $X_i$ are not normally distributed is obtained. The form of this expansion is Prob $(t

A total of 129 midlife women who have lived in seoul, Kyeung ki and Kangwon were selected conveniently and data were collected by structured questionnaire from May to June, 1998. The instruments were the menopausal symptoms scale developed by Neugarten, Ci Sung-Ai & Kim Hy-Eun. Data analysis was done by Chi-square test, ANOVA, t-test. The results of this study were summarized as follows ; 1. The mean score for the menopausal symptoms of midlife women was 2.12. Serious menopausal symptoms which could be found in this study were "joint pain and numbness of arm and leg"(2.63), "fatigue and powerlessness"(2.58), "nervousness"(2.44). Over 97.8% of women complained menopausal symptoms. 2. In the relationship between social demographic variables and menopausal symptoms of midlife women were significant difference in urban area and rural area(t=-4.569, P=.000), marriage status(F=4.809, P=.010), education(F=7.359, P=.000), married son and daughter(F=7.359, P=.000), mensturational status(F=5.993, P=.003), and satisfaction to husband(F=9.093, P=.000). 3. In the relationship of menopausal symptoms of midlife women between two groups were statistically significant differences(t=-4.569, P=.000). The mean score of menopausal symptoms of rural women(2.34) were higher than those of urban women(1.85). This study shows the possible implication for nursing intervention of midlife women's health to prevent and relieve menopausal symptoms.

Among solute carrier proteins, the organic anion transporters (OATs) play an important role for the elimination or reabsorption of endogenous and exogenous negatively charged anionic compounds. Among OATs, SLC22A9 (hOAT7) transports estrone sulfate with high affinity. The net decrease of estrogen, especially in post-menopausal women induces rapid bone loss. The present study was performed to search the SNP within exon regions of SLC22A9 in Korean females with osteoporosis. Fifty healthy controls and 50 osteoporosis patients were screened for the genetic polymorphism in the coding region of SLC22A9 using GC-clamped PCR and denaturing gradient gel electrophoresis (DGGE). Six SNPs were found on the SLC22A9 gene from Korean women with/without osteoporosis. The SNPs were located as follows: two SNPs in the osteoporosis group (A645G and T1277C), three SNPs in the control group (G1449T, C1467T and C1487T) and one SNP in both the osteoporosis and control groups (G767A). The G767A, T1277C and C1487T SNPs result in an amino acid substitution, from synonymous vs nonsynonymous substitution arginine to glutamine (R256Q), phenylalanine to serine (F426S) and proline to leucine (P496L), respectively. The Km values and Vmax of the wild type, R256Q, P496L and F426S were 8.84, 8.87, 9.83 and $12.74{\mu}M$, and 1.97, 1.96, 2.06 and 1.55 pmol/oocyte/h, respectively. The present study demonstrates that the SLC22A9 variant F426S is causing inter-individual variation that is leading to the differences in transport of the steroid sulfate conjugate (estrone sulfate) and, therefore this could be used as a marker for certain disease including osteoporosis.

Working depth of the model net was determined by using of the same experimental tank and the same model net that used in the forwarded report in a series studies. The depth of the net which indicates the depth of the head rope from the water surface, was determined by the photographs taken in front of the net mouth with the combination of towing velocity, warp length and distance between paired boats. The results obtained can be summarized as follows: 1. Working depth of model nets A and B was varied in the range of 0.09~1.66$m$,and 0.04~1.34$m$(which can be converted into 2.7~40.2$m$and 1.2~49.8$m$in the full-scale net) respectively, and the depth of model net A was slightly deeper than the depth of the model net B. 2. Working depth ($D$,which is appendixed m for the model net, f for the full-scale net, A and B for the types of the model nets) can be expressed as the function of towing velocity$V_t$, as in the model net($V_t$=$m$/$sec$) $D_{mA}$=(-1.99+0.65$L_w$) $e^{-1.72V_t}$ $D_{mA]$=(-1.91+1.04 $L_w$) $e^{2.88V_t}$ in the full-scale net($V_t$=$k$'$t$ $D_{fA}$=(-29.32+0.65$L_w$)$e^{0.40 V_t}$ $D_{fB}$=(-57.60+1.04$L_w$)$e^{-0.67 V_t}$ 3. Working depth 9$D$ appendixes are as same as the former) can be expressed as the function of warp length$L_w$) in the model net, and can be converted into full-scale net as in the model net ($V_t$=$m$/$sec$) $D_{mA}$=-0.99 $e^{-1.42V_t}$+0.67$e^{-1359V_t}$$L_w$ $D_{mB}$=-.258$e^{-3.77V_t}$+1.16$e^{-3.15V_t$ $L^w$, in the full-scale net($V_t$=k't) $D_{fA}$=-29.28$e^{-0.32V_t}$+0.67$e^{-0.37V_t$$L_w$ $D_{fB}$=-69.10$e^{-0.81V_t}$+1.16$e^{-0.72V_t}$$L_w$. 4. Working depth was gradually shallowed according to the increase of the distance between paired boats.
