Purpose: Objective of this study was to investigate how often nurses to perform patient safety activities. Methods: 521 observations were collected in 9 hospitals by 107 nursing students. Nurses' patient safety care activities were measured 0 (not at all) to 10 (all the time) scores. Descriptive statistics, independent t-test, one way ANOVA, correlation, multiple regression used to analyse data. Results: Items like 'Initial nursing assessment', 'drug management bring on', 'preparation for radiology test', 'falls assessment', 'nursing record' got high scores. But, scores of 'patient identification', 'verbal order management', 'hand hygiene' were lower than others. Each scores were different significantly according to institutions and departments. Within a same institution, the variance of scores, especially in 'patient identification', 'hand hygiene' were great. Scores of activities were different according to characteristics of institutions like type, location, number of beds, teaching hospital, number of accreditation, JCI accreditation. Predictors influencing nurses' patient safety activities were type, location and accreditation. These predictors account for 19.4% of variance. Conclusion: Performance of nurses' patient safety activities were different significantly according to characteristics of institutions. The important items like 'patient identification', 'hand hygiene' had achieved lowest performance. Further researches are needed to improve the basic safety activities.

Purpose: This study was aimed to compare and contrast the evaluation scores on students OSCE performance between the instructors and students according to the Bloom's taxonomy. Methods: A total of sixty six students in a nursing college in Seoul, Korea and four instructors were recruited in the study. The 28 sophomore students were assigned to an OSCE on intravenous injection, whereas 38 junior students on tracheostomy care. Knowledge levels were measured by the students using the researcher developed knowledge questionnaires, and the attitudes and skills by the students and instructors by the modified clinical performance checklists. The data were analyzed by SPSS 22.0 program. Results: For knowledge, the higher GPA of the previous semester was only significant factor of higher knowledge scores. There were statistically significant differences in scores of total (t=-2.740, p=.008) and skill (t=-2.528, p=0.014), but not in attitude between the instructors and students' evaluations. The students evaluated their skill scores significantly higher than those of the instructors. For knowledge, the higher GPA of the previous semester was the only significant factor of higher knowledge scores. In attitude scores, the students in higher grade significantly overestimated themselves (t=3.076, p=.003). Conclusion: Clinical performance assessment requires methodological validity and reliability for student to attain necessary clinical skills properly and efficiently. The findings of this study mandate various assessment methods for nursing simulation evaluations to be valid.

We investigated how bibliometric indicators such as publication count and citation count affect the assessment of research performance by computing various bibliometric scores of the works of Korean LIS faculty members and comparing the rankings by those scores. For the study data, we used the publication and citation data of 159 tenure-track faculty members of Library and Information Science departments in 34 Korean universities. The study results showed correlation between publication count and citation count for authors with many publications but the opposite evidence for authors with few publications. The study results suggest that as authors publish more and more work, citations to their work tend to increase along with publication count. However, for junior faculty members who have not yet accumulated enough publications, citations to their work are of great importance in assessing their research performance. The study data also showed that there are marked differences in the magnitude of citations between papers published in Korean journals and papers published in international journals.

This study investigates the effects of soft story, short columns, heavy overhangs, pounding, and construction and workmanship quality parameters on seismic response of reinforced concrete buildings through nonlinear static and dynamic procedures. The accounted parameters are selected for their common use in rapid screening of RC buildings. The 4- and 7-story buildings designed according to pre-modern codes are used to reflect majority of the existing building stock. The relative penalty scores are employed in this study to evaluate relative importance of certain irregularities in the existing rapid seismic assessment procedures. Comparison of relative scores for the irregularities considered in this study show that the overall trend is similar. The relatively small differences may be accounted for regional construction practices. It is concluded that initial-phase seismic assessment procedures based on architectural features yield in somewhat similar results independent of their bases. However, the differences in the scores emphasize the proper selection of the method based on the regional structure characteristics.

A common approach to the problem of predicting student test scores is based on the student's previous educational history. In this study, high school transcripts of about two thousand candidates, who took the High-school Student Assessment (HSA) were collected. The data were estimated through building a regression model - Random Forest and optimizing the model's parameters based on Genetic Algorithm (GA) to predict the HSA scores. The RMSE (Root Mean Square Error) measure of the predictive models was used to evaluate the model's performance.

A CCTV inspection method has been widely used to assess sewer condition and performance, but Korea lacks a proper decision support system for prioritizing sewer repair and rehabilitation (R&R). The objective of this paper is to introduce the results that we have developed in the Sewer Condition Assessment and Rehabilitation Decision-making (SCARD) Program using MS-EXCEL. The SCARD-Program is based on a standardized defect score for sewer structural and hydraulic assessment. Priorities are ranked based on risk scores, which are calculated by multiplying the sewer severity scores by the environmental impacts. This program is composed of three parts, which are decision-making for sewer condition and performance assessment, decision-making for sewer R&R priority assessment, and decision-making for optimal budget allocation. The SCARD-Program is useful for decision-makers, as it enables them to assess the sewer condition and to prioritize sewer R&R within the limited annual budget. In the future, this program logic will applied to the GIS-based sewer asset management system in local governments.

Purpose:The healthcare system of South Korea is at the extreme of the dispersed system. Few regulations limit patients from directly visiting higher-level medical institutions for primary care sensitive conditions. As a result, similar to local clinics, general and tertiary teaching hospitals also provide diverse primary care services. Our study aimed to examine the general public's perceptions of their primary care performance. Methods: Face-to-face surveys were conducted with 1000 adults who were living in South Korea with the aid of a questionnaire that included the Korean Primary Care Assessment Tool (KPCAT). The KPCAT consists of five domains, which are the main indicators of primary care performance: first contact, comprehensiveness, coordination, personalized care, and family/community orientation. One-way analysis of variance and post hoc tests were used to compare the KPCAT scores across the three types of medical institutions. Results: Domain-wise analyses revealed two different patterns. With regard to first contact and its subdomains, the highest and lowest scores emerged for local clinics and tertiary teaching hospitals, respectively. However, the other four domain scores were significantly lower for local clinics than for the other two types of medical institutions. Conclusions: Local clinics were perceived to be medical institutions that are responsible for providing primary care. However, the general public perceived only one domain of their primary care to be superior to that of the other two types of medical institutions: first contact. National efforts should be taken to strengthen their other four domains of primary care by training their workforce and providing appropriate incentives.

The purpose of Green Building Certification System is to promote the environment-friendly building construction as the life-cycle environmental performance of a certain building is assessed and certified nationally(domestically). By the way, a building can get the green building certificate just with the minimum standard in prerequisite assessment criteria and with the designated scores in totals. GBCS consists of 9 assessment issues and it has 4 grades. Nevertheless the 1st. grade green building has uneven scores in each issue. In other words, it has even 0 point in a special issue. Due to the above problem, the discrimination and reliability in the GBCS grading and scoring has to be secured. This study aims at a new grading and scoring system equipped with the discrimination and reliability through analysing the scores of prerequisite assessment criteria and the scores by issues in the actually certified green office buildings.
