The study was carried out to identify the relationship of patients' self-rating and nurses' rating on health literacy of hospitalized patients. Data were collected using the Korean Functional Health Literacy Test (KFHLT) which was revised for hospitalized patients and Single Item Literacy Screener. A total of 178 subjects, which consisted of 89 hospitalized patients and 89 nurses taking care of them, were recruited from medical and surgical wards of E university hospital. Collected data were analyzed using SPSS 23.0 program. The results showed that the average health literacy score of the subjects was $11.45{\pm}4.22$ out of 17 and the average correct answer rate was 67.3%. Patient health literacy was significantly different by age, education, occupation and reading handouts. The patients' self-rating had significant correlation with health literacy measured by KFHLT while nurses' rating did not. There was no significant correlation between patients' self-rating and nurses' rating. The findings suggest that patients' self-rating might be available to assess patient health literacy in hospitals and a careful approach is required when nurses use a single-item rating.

In this paper, we propose a novel construction scheme for the personalized e-Learning system based on IRT(item response theory), which can be applied to the content including non-hierarchical and horizontal learning objects in its learning nodes. Especially the proposed system performs tests and re-estimates examinee ability during the learning nodes are operating so that the results are directly applied to the next node. This scheme can be called a dynamic relationship between test and learning which is totally different from conventional customization based on learning procedures separated from test steps. Moreover, we should periodically modify the averages of node difficulties, item parameters, and ability parameters of students so that the system have more accurate personalized learning capability. As a result, this scheme maximizes learning efficiency offering the most appropriate learning objects and items to the individual students according to their estimated abilities and the system itself should obtain continuous improvements by modifying the parameters and fulfilling periodical feedbacks.

This study was conducted to investigate the relationship among major satisfaction (MS), clinical competence (CC), career decision-making self-efficacy (CDMS), and career decision level (CDL) for undergraduate nursing students. A self-report instrument was used to measure MS, CC, CDMS, and CDL. Questionnaires were completed by 307 nursing students in three nursing colleges, and path analysis was employed to validate the proposed model and analyze the causal relationships among variables. Four constructs (MS, CC, CDMS, and career decision) were analyzed. To build a path model, MS and CC were linked to CDMS and career decision. The initial analysis suggested that the modification needed modification; therefore, a covariance link was added. The overall goodness of fit for indices indicated satisfactory path analysis. The indices were revealed as $x^2=2412$, GFI=0.996, AGFI=0.961, and RMSEA=0.068. As a result, the proposed model was acceptable with a good fit, and there were significant direct and indirect effects of paths in the model. Specifically, MS and CC had a direct influence on CDMS, and MS and CDMS directly affected CDL. Moreover, MS and CC had indirect effects on CDL through CDMS. These results imply that students' CDMS should be seriously considered when designing counseling programs for career guidance, and substantiality of CC education is needed to improve CDMS. These results may provide a practical guideline to provide educational intervention for nursing students.

While transforming the inelastic system into the equivalent elastic one gives an advantage of simpler analysis, the actual inelastic behavior of the system is hardly modeled in the capacity spectrum method (CSM). Therefore, the accuracy of CSM depends on the precise estimation of equivalent period and damping ratio as well as the modification of the elastic response spectrum and the corresponding demand spectrum. In this paper, the effect of demand spectrums on the accuracy of CSM is evaluated. First, the response reduction factors provided in ATC-40 and Euro Code are evaluated. Numerical analysis results indicated that the acceleration responses obtained using the factor of Euro Code are closer to the actual response than those obtained using the factors of ATC-40. Next, the accuracy of CSM is evaluated constructing the demand spectrum using the absolute acceleration responses and pseudo acceleration responses. The results obtained using the absolute acceleration responses were found to be generally larger than those obtained using the pseudo ones. Since CSM often underestimates the response, the use of absolute acceleration response gives the response relatively closer to the exact ones. However, the difference becomes negligible as the hardening ratio and the yield strength ratio become larger.

The objective of this study was to test the effect of catalase on penetration in vitro by spermatozoa preincubated with xanthine and/or xanthine oxidase. The penetration rates were, significantly (p<0.05) higher in spermatozoa preincubated without (66 and 38%) than with (40 and 15%) catalase for 0 and 30 min. When spermatozoa were preincubated and inseminated in medium with xanthine, the penetration rates were significantly higher (p<0.05) in medium with (68, 70 and 49% for 0, 30 and 60 min) than without (33, 41 and 19% for 0, 30 and 60 min) catalase. However, in oocytes were' inseminated with spermatozoa pre incubated with or without catalase in the presence of xanthine oxidase, no decrease in penetrations rates were observed for up to 60 min of preincubation. In another experiment, the penetration rates were significantly (p<0.00l) higher in medium with (75, 55 and 52%) than without (14, 4 and 8%) catalase when oocytes were inseminated with spermatozoa preincubated for 0, 30 and 60 min in the presence of xanthine plus xanthine oxidase. On the other hand, The rate of polyspermy in oocytes penetrated in medium without catalase in the presence of xanthine or xanthine plus xanthine oxidase decreased with time of spermatozoa preincubation. However, no differences were observed in polyspermy rates in the medium with xanthine oxidase alone despite presence of catalase. These results indicate the advantages of spermatozoa pre incubated with xanthine plus xanthine oxidase in the presence of catalase to increase penetration potential and with suppressed polyspermy in porcine.

This paper presents an Modified Orthogonal Neural Network(MONN), new modified model of Orthogonal Neural Network(0NN) based on orthogonal functions, and applies it to nonlinear system approximator. ONN proposed by Yang and Tseng, doesn't have the problems of traditional multilayer feedforward neural networks such as the determination of initial weights and the numbers of layers and processing elements. And tranining of ONN converges rapidly. But ONN cannot adapt its orthogonal functions to a given system. The accuracy of ONN, in terms of the minimal possible deviation between system and approximator, is essentially dependent on the choice of basic orthogonal functions. In order to improve ability and effectiveness of approximate nonlinear systems, MONN has an input transformation layer to adapt its basic orthogonal functions to a given nonlinear system. The results show that MONN has the excellent performance of approximate nonlinear systems and the input transfnrmation makes the ability of MONN better than one of ONN.
