Multiple cohorts (e.g., current students and graduates) were formed to collect information on the entire educational process from admission to graduation regarding students' educational performances at Kosin University College of Medicine. Data that had already been collected and analyzed by different committees for different purposes were grouped into a more systematic and comprehensive system called the cohort system, enabling the necessary data to be collected promptly and analyzed in accordance with the purpose of providing meaningful information in each area of the educational process. Therefore, comprehensive cohort data that can be used for mission statement revision, curriculum development and improvement, student counseling, and student selection were established and utilized. The cohort data were collected from performance evaluation indicators including self-evaluation surveys, evaluation tools for learning outcomes, academic achievement, results of the Korean Medical Licensing Examination, and career placement. Based on the results obtained by analyzing cohort data, a comprehensive cohort report has been published. The data analyzed through the cohort were reported to each committee and used in various ways. Currently, however, only some data have been analyzed and used. In the future, after complete data collection, the cohort data can be used as meaningful basic data for achieving the institution's mission and educational goals, developing and improving the curriculum, counseling students, and selecting students through the analysis of learning performance data from student admission to graduation and after graduation.

The high cost of ultra-high-performance engineered cementitious composite (UHP-ECC) is currently a crucial issue, especially in terms of the polyethylene (PE) fibers use. In this paper, cheap calcium carbonate whiskers (CW) were evaluated on the feasibility of hybrid with PE fibers. Diverse combinations of PE fibers and CW were employed to investigate the multi-scale enhancement on the UHP-ECC performance. A probabilistic-based UHP-ECC tensile strain reliability analysis approach was utilized, which was in general agreement with the experimental results. Furthermore, a multi-dimensional integrated representation was conducted for the comprehensive assessment of UHP-ECC. Results illustrated that CW improved the compressive strength and energy dissipation capacity of UHP-ECC owing to the microscopic strengthening mechanism. CW and PE fiber further promoted the saturated cracking of composite by multi-scale crack arresting effect. In particular, PE1.75-CW0.5 specimen possessed the best overall performance. The ultimate cracking width of PE1.75-CW0.5 group had 98 ㎛, which was 46.18% lower compared to PE2-CW0 group, the 28d compressive strength were slightly improved, the tensile strain capacity was comparable to that of PE2-CW0 group. The results above demonstrated that combinations of PE fiber and CW could significantly enhance the comprehensive performance of UHP-ECC, which was beneficial for large-scale engineering applications.

Purpose: This study aimed to investigate whether the comprehensive nursing care service positively affected accidental falls and pressure injuries. Methods: This study was a retrospective study that analyzed the accidental falls and pressure injuries cases in an acute care hospital located in Seoul and compared the rates of accidental falls and pressure injuries before and after the comprehensive nursing care service was operated. Results: Comparing the accidental fall incidence rates per 100 person-months between a comprehensive nursing care ward and a general ward, it showed fewer accidental falls by 0.44 in comprehensive nursing care wards, but the result was not statistically significant. In the case of pressure ulcers, the incident rate per 100 person-month was 6.17 in general wards and 4.77 in comprehensive nursing care wards, which showed that the number of pressure ulcer patients was lower in comprehensive nursing care wards, however it was also not statistically significant. Conclusion: It is not confirmed that the operation of the comprehensive nursing care service contributes to the reduction of accidental hospital falls or pressure injuries. Follow-up studies are recommended to determine the effectiveness of comprehensive nursing services in quality indicators.

Mental workload (MWL) is a major consideration for the user interface design in nuclear power plants (NPPs). However, each MWL evaluation method has its advantages and limitations, thus the evaluation and control methods based on multi-index methods are needed. In this study, fuzzy comprehensive evaluation (FCE) theory was adopted for assessment of interface designs in NPP based on operators' MWL. An evaluation index system and membership functions were established, and the weights were given using the combination of the variation coefficient and the entropy method. The results showed that multi-index methods such as performance measures (speed of task and error rate), subjective rating (NASA-TLX) and physiological measure (eye response) can be successfully integrated in FCE for user interface design assessment. The FCE method has a correlation coefficient compared with most of the original evaluation indices. Thus, this method might be applied for developing the tool to quickly and accurately assess the different display interfaces when considering the aspect of the operators' MWL.

The purpose of this study was to identify the health promotion behavior and its related factors of persons who wanted a comprehensive health check-up in order to provide a basis for health education to promote health enhancing behavior. Study variables were induced from Pender's Health Promotion Model. The subjects were 160 persons who had a check-up at the health promotion center in a university hospital in Tae-Gu, between September 8 and 22, 1998. The following instruments were used in the study : Lee Tae Wha's Health Promoting Life-style Profile, Park Chai soon's Self-efficacy Instrument and Moon Jeong Soon's Perceived Benefit and Barrier Instrument. Data was collected by self-reporting questionnaire. Analysis of the data was done by SAS program, t-test, ANOVA and Pearson-Correlation Coefficient. The results of this study were as follows. 1. The average score for the health-promotion behavior was 104.64. In the subcategories, self-actualization showed the highest degree of performance and physical exercise showed the lowest degree of performance. 2. In the relation of general characteristics of subjects to the level of health-promoting behavior, the male, the married, the group with several symptoms showed a high level of health-promoting behavior. 3. The relationship between the degree of performance in health-promotion behavior and its correlates were as follows: Self-efficacy was positively correlated to health promotion behavior, while the perceived barrier was correlated negatively. But the perceived benefit did not show a significant correlation with health promotion behavior. Results suggest that the development of programs with strategies to strengthen doing physical exercise and concerning health, increase self-efficacy and exclude the barriers to health promotion is recommended to individuals seeking a comprehensive health check-up.

Technology plays an important role in e-Government with people and policies to make e-Government more efficient. And much attention and investment has been given to the technological development, so called informatization, of electronic government (e-Government) in Korea. But the measures of quality and efficiency for the e-Government initiatives have not been verified well. For this reason, a great deal of effort has been devoted to develop the measurement of e-Government system; however, a measurement model to support such effort has not been developed enough yet. In this empirical study, we proposed a comprehensive theoretical model for measuring performance of e-Government initiatives and analyzed such model through 112 collected questionnaires from people in charge of informatization in central government administrations.

In order to achieve the comprehensive rehabilitation, ultra high performance cementitious composites is proposed to existing RC parapet rehabilitation. The influence factors of UHPCC rehabilitation includes two parts, i.e., internal factors related with material, such as UHPCC layer thickness, corrosion ratio of rebars, fiber volume fraction, and external factors related with the load, such as impact speeds, impact angles, vehicle mass. The influence of the factors was analyzed in this paper based on the nonlinear finite element. The analysis results of the maximum dynamic deformation and the peak impact load of parapets revealed the influence of the internal factors and the external factors on anti-collision performance and degree degradation. This research may provide a reference for the comprehensive multifunctional rehabilitation of existing bridge parapets.

The importance of Information technology (IT) has been growing. Thus, it is critical for firms to choose the optimal information technology development mode in order to ensure that maximum benefit is derived from IT. Despite its importance, however, there is little comprehensive research on choosing the IT development mode that firms undertake. To fill this gap, this study attempts to propose a parsimonious as well as comprehensive IT development framework based on strategic value and the uniqueness of IT resources. In addition, this study analyzes the impact of the fit between the theoretically proposed IT development mode and the actually used mode on the performance of Korean firms. This study contributes to and expands the literature on IT development modes by considering various development modes in real time. Moreover, the results serve as a stepping stone for managers who want to develop or adopt IT effectively.

Entering the era of low growth due to changes in social and economic conditions, most cities across the country are actively promoting urban regeneration. Although urban regeneration is a project with huge national finances, a clear evaluation system has not yet been established. In order to ensure the sustainability of urban regeneration, it is necessary to secure the validity of urban regeneration policies and establish a reflux system to supplement the policies. The purpose of this study is to derive the limitations of the existing comprehensive performance evaluation and to develop an improved urban regeneration policy comprehensive performance evaluation technique based on spatial big data. The urban regeneration comprehensive performance evaluation technique differentiated the areas affected by the urban regeneration project and the surrounding areas based on the type of urban regeneration project and the presence or absence of large cities and middle cities. The effects of urban regeneration were quantitatively verified through relative comparison between the areas affected by urban regeneration projects and the surrounding areas of population, society, economy, industry, physical and environmental evaluation indicators.
