Purpose: The purpose of this study was to evaluate the effects of standardized patient simulation on nursing students' communication skills, problem-solving skills, critical thinking dispositions, and clinical competency. Methods: A one-group pretest-posttest design was used. Data were collected from a convenient sample of 47 junior nursing students at W University. Scenarios to train SP and checklists to evaluate the students''competence were developed by our research team. The collected data were analyzed with descriptive analysis t-test, Pearson's Correlation Coefficient and Cronbach's ${\alpha}$ using SPSS WIN 21.0 Program. Results: The simulation practicum using a standardized patient was conducted based on four steps, namely, selections of scenario modules, standard patient training, implementation, and evaluation. The differences between the pre and post-test scores of problem-solving skills(t=-2.94, p=.005) and clinical competency(t=-2.84, p=.007) were statistically significant. But communication skill(t=-.32, p=.747) and critical thinking(t=-.68, p=.498) was not different in group. Conclusion: Standardized patient simulation in nursing education may be useful the improvement of problem-solving skills and clinical competency.

Oxidative stress potentially induces neurotoxicity which is believed to underlie several major age-related diseases of the central nervous system. This study sought to identify the cytoprotective effects of sixty-nine Cambodian plants against glutamate-induced cell death. Cultured HT22 cells were applied as an in vitro model, and neurotoxicity was induced in these neuronal cells by exposure to a determined concentration of glutamate. Sixty-nine plant sources, as Cambodia's indigenous species, were purchased from O'reusey Market, Phnom Penh, and extracted with ethanol. These extracts were screened for cytoprotective effects against glutamate-triggered neurotoxicity in HT22 cells at concentrations of 100 and 300 ${\mu}g/ml$. Of these, eight ethanol extracts, bark of Anacardium occidentale, bark and sapwood of Bauhinia pulla, flowers of Borassus flabellifer, stems and leaves of Coix lacryma-jobi, bark and sapwood of Diospyros nitida, sapwood of Dipterocarpus obtusifolius, stems of Oryza rufipogon, and fruits of Phyllanthus emblica, showed significant cytoprotective effects against glutamate-induced cell damage and degeneration in HT22 cells.

Background: The purpose of this study was to propose a method for developing a measure of hospital-wide all-cause risk-standardized readmissions using administrative claims data in Korea and to discuss further considerations in the refinement and implementation of the readmission measure. Methods: By adapting the methodology of the United States Center for Medicare & Medicaid Services for creating a 30-day readmission measure, we developed a 6-step approach for generating a comparable measure using Korean datasets. Using the 2010 Korean National Health Insurance (NHI) claims data as the development dataset, hierarchical regression models were fitted to calculate a hospital-wide all-cause risk-standardized readmission measure. Six regression models were fitted to calculate the readmission rates of six clinical condition groups, respectively and a single, weighted, overall readmission rate was calculated from the readmission rates of these subgroups. Lastly, the case mix differences among hospitals were risk-adjusted using patient-level comorbidity variables. The model was validated using the 2009 NHI claims data as the validation dataset. Results: The unadjusted, hospital-wide all-cause readmission rate was 13.37%, and the adjusted risk-standardized rate was 10.90%, varying by hospital type. The highest risk-standardized readmission rate was in hospitals (11.43%), followed by general hospitals (9.40%) and tertiary hospitals (7.04%). Conclusion: The newly developed, hospital-wide all-cause readmission measure can be used in quality and performance evaluations of hospitals in Korea. Needed are further methodological refinements of the readmission measures and also strategies to implement the measure as a hospital performance indicator.

This study reviews an English enhancement course implemented for medical and nursing college students of 2011 to improve their standardized English test scores. A total of 117 first-year students underwent the pre-test and the post-TOEIC in November 2011. After the pre-test, lectures on listening enhancement strategies and problem solving tactics on reading comprehension were supplemented with 4 times of enhancement-tests. Their pre- and post-TOEIC results were compared to see if such enhancement strategies were effective to improve their TOEIC scores. It was further to investigate, through survey questionnaires, how the subjects felt about a number of pre-test-type TOEIC exercise with what-to-listen and how-to-infer listening strategies and pattern-drill practices for reading comprehension. It was found that the scores of listening comprehension improved significantly for both major students whereas reading scores showed slight decrease among nursing majors. It is concluded that administering numerous pre-test-type-TOEIC exercise is effective for students to improve their listening scores supplemented with listening strategies Also, students' response showed positive toward the enhancement course.

A selected subject and a standardized scoring system were newly enforced at college entrance examination from 1999. A selected subject system means each student can select one subject in addition to common subject in the field of mathematical research II and a standardized scoring system means we standardize the score of each field as mean 50 and standard deviation 10 in order to adjust the degree of difficulty between fields. In the field of mathematical research II, there may exist not only difference of the degree of difficulty but also that of general studying ability between groups of selected subjects. So when we standardize score, we have to consider them. So far a linear equating which is a parametric method and an equi-percentile equating which is a nonparametric method have been published, but both of them supposed that the general studying ability between groups was equal. So in this paper an adjusted linear and percentile equating method which seems to be adequate to our entrance examination is suggested and is investigated by computer simulation.

This study was aimed to verify the acceptable contact force between power collector and 3rd rail type conductor rail for the Korean standardized rubber-tired AGT light rail vehicle. The power collector was designed and manufactured to satisfy the Korean standardized Specifications of the rubber-tired AGT light rail vehicle. Based on the dynamic behavior, contact force variation and interruption in the worst installation tolerance of the conductor rail, its initial contact force was set up. At the test track for the Korean standardized rubber-tired AGT light rail vehicle, interruptions, stresses, vibrations, and contact force variations were measured. As the results, initial contact force was verified to ensure power collection stability.

Recently a number of social surveys on community response to environmental noises have been conducted to summarize response relationship obtained from different areas. Some problems have been pointed out in comparing the result of surveys using verbal scales with different number of categories. ICBEN (International Commission on Biological Environment of Noise) Team 6 planned a international joint study and constructed comparable standardized noise annoyance scales using the same method. In Korea the survey was conducted in four areas such as Seoul, Taejon, Taegu, Kwangju. About 100 subjects participated in each area approximately. Finally five verbal annoyance were constructed as follows; 1 (Jeonhyu), 2 (Jokm), 3 (Bikyojerk), 4 (Ajoo), 5 (Umcheongnage).

The automatic/driverless operation which are great important techniques in metro railway are required to increase higher safety, greater reliability, and transport capacity. To satisfy such demands, we must have the system design and testing technique for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS(Train Control and Monitoring System), ATO(Automatic Train Operation), ATC(Automatic Train Control), and TWC(Train to Wayside Communication). These sub-systems must be interfacing with not only each others but also the signal system on the ground. We tested the train control system on Test line that has been developed on the basis of the standardized type EMU for korea railway systems. This test line which is located in Sangju, have been constructed for testing 7 ＆ 8 line of Seoul Metro railway.

The hospital readmission rate has been widely used as an indicator of the quality of hospital care in many countries. However, the transferrability of this indicator that has been developed in a different health care system can be questioned. We reviewed what should be considered when using the risk-standardized readmission rate (RSRR) as a generic quality indicator in the Korean setting. We addressed the relationship between RSRR and the quality of hospital care, methodological aspects of RSRR, and use of RSRR for external purposes. These issues can influence the validity of the readmission rate as a generic quality indicator. Therefore RSRR should be used with care and further studies are needed to enhance the validity of the readmission rate indicator.
