This is a study on perception errors of Korean stops in word initial position. This study will show how listeners perceive manipulated Korean stops through two experiments and I will analyze why they are confused. In addition, 1 will show those perception errors not only reflect the relationship between the place and manner of articulation but also ate deeply related to the length of aspiration.

Purpose: This study was carried out to investigate perception and experience of medication errors by nurses. Method: Data collection through a survey was performed using structured questionnaires over the period of September 1 to October 15, 2004. Questionnaire were delivered to 222 nurses from 15 hospitals; thereafter, 205 questionnaires were responded (i.e., 92% response rate). The subject in the study was a nurse who had been working in the hospital for less than one year. Results: The average perception rate was 87.5%. The perception rates of subjects in medication errors from four areas are 62% in wrong dosage form for drug administration, 61.5% in air into an IV set, 63% in crystals in an IV lines, and 83.5% in wrong time. The experience rates of subjects in medication errors from four areas are 85.5% in wrong time, 39.5% in wrong injection site, 34.5% in omission error, and 28% in wrong patient. Conclusion: The average perception rate and experience rates of medication errors were 87.5% and 23.5%, respectively. Education about the Five right in medication and knowledges about drugs would improve the perception of medication errors of nurses whose work experience is less than one year, and prevent them from medication errors.

This study examined the perception and production of Korean lax, fortis and aspirated stops in three apraxic patients. All of tile subjects made more production errors than perception errors. This indicates that apraxic patients have problems in phonetic execution rather than phonological representation. Additionally, in both production and perception, there were more errors in non-word-initial consonants than in word-initial consonants. These findings contradict those of the previous studies which report more errors in word-initial consonants. This study also found that, unlike previous studies in the types of errors made, distortion errors were high in both non-word-initial and word-initial consonants in apraxic patients. Generally, VOT of the stops showed significant differences among lax, fortis, and aspirated stops, which indicates that there is a failure not in choosing the appropriate stop but in positioning or motor planning at the articulation stage.

Purpose: Human factor is one of the major causes of medication errors. The purpose of this study was to identify nurses' perception and experience of medication errors, examine the relationship of Dominance, Influence, Steadiness, Conscientiousness (DISC) behavior patterns and medication errors by nurses. Methods: A descriptive survey design with a convenience sampling was used. Data collection was done using self-report questionnaires answered by 308 nurses from one university hospital and two general hospitals. Results: The most frequent DISC behavioral style of nurses was influence style (41.9%), followed by steadiness style (23.7%), conscientiousness style (20.4%), and dominance style (14.0%). Differences in the perception and experience level of medication errors by nurses' behavioral pattern were not statistically significant. However, nurses with conscientiousness style had the lowest scores for in experience of medication errors and the highest scores for perception of medication errors. Conclusion: The results of this study show that identification of the behavior pattern of nurses and application of this education program can prevent medication errors by nurses in hospitals.

Integral imaging is a three-dimensional display method which has full parallax and continuous viewpoints. However, we found an error between the depth expressed by integral imaging and the depth perceived by the observer through binocular disparity. We analyze the depth perception errors of the threedimensional image constructed by integral imaging.

The objectives of this study were (1) to describe doctors' perception and attitudes toward patient safety culture and medical error reporting in their working unit and hospitals, (2) to examine whether these perception and attitudes differ by doctors' characteristics, such as sex, position, and specialties, and (3) to understand the relationship between overall perception of patient safety in their working unit and each sub domain of patient safety culture. A survey was conducted with 135 doctors working in a university hospital in Korea. After descriptive analyses and chi-square tests of subgroup differences, a multivariate-regression of overall perception of patient safety in their unit with sub-domains of patient safety culture was conducted. Overall, a significant proportion of doctors expressed negative perception of their working units' patient safety culture, many reporting potentials for patient safety problems to occur in their unit. They also negatively viewed their hospital leadership's commitment on patient safety. Regarding the patient safety in their working unit, doctors were most worried about staffing level and observance of safety procedures. Most doctors did not know how and which medical error to report. They also perceived that medical errors would work against them personally and penalize them. About 22 percent of respondents believed that even seriously harmful medical errors were not reported.

Purpose: The objective of this study was to examine patient safety culture (PSC) and patient safety initiatives (PSI) according to IT-based medication errors prevention system which is constructed in this study, and to identify the relationships among system construction, perception to the usage, PSC and PSI. Methods: The subjects were 180 nurses who work at 12 different hospitals with over 300 beds. The questionnaire included the characteristics of participants, a system construction status, the perception to the usage using electric pharmacopoeia (EP), a drug dose calculation system (DDCS), a patient safety reporting system (PSRS) and a bar-code system (BS). The data were collected from July 2011 to August 2011. Descriptive statistics, ANOVA, Pearson correlation and MANOVA were used for data analysis. Results: Systems were constructed in participating hospitals; For EP and PSRS, 83.9%, DDCS, 50%, and BS, 18.3%. The perceptions on the usage of the system were marked highest in BS as 4.54 followed by EP as 3.85. There were significant positive correlations between PSI and EP construction (r=.17, p=.028); PSRS (r=.17, p=.028) and DDCS (r=.23, p=.002). Conclusion: The developed system for improving the user experiences and reducing medication errors was found out well accepted. It is hoped that the system is helpful for PSC and PSI improvement in clinical settings.

Eleven Korean learners of English took part in an experiment where the production and perception of English /r/ and /l/ in four different word positions was investigated. Overall the subjects made more errors on /l/ in both production and identification tests. The frequency of the subjects' errors was also sensitive to word positions in which the two English liquids occur. Especially the subjects made noticeably fewer errors in intervocalic medial position. It is suggested that the Korean subjects' acquisitional pattern in this particular case of foreign phone learning can be explained more by language particular 'interference' effects rather than 'universal' acoustic arguments such as those given in Dissosway et a1. (1982) and Sheldon and Strange (1982). The results of the experiment also support the minority position among second language educators that in some cases of non-native phone acquisition, learners' production abilities can be developed earlier than their perceptual abilities.

The purpose of this study was to investigate the characteristics of error types in naming task for 8 questionable demeatia groups, 9 definite dementia groups, and 10 normal groups. The items of naming error analysis were classified into visual perception errors, semantic association errors, semantic non-correlation errors, phoneme errors, Don't Know, and No Response. For the analysis, descriptive statistics analysis, analysis of variance, and multivariate analysis of variance were conducted using SPSS 21.0. As a result, there was a significant difference in the error rate between groups according to the error type. The errors that showed significant differences between the normal group and the other two groups were visual perception errors and semantic non-related errors. The error of non-response was different from the dementia confirmation group, but there was no significant difference from the dementia suspicion group. These results showed that Alzheimer's patients had a defect in confrontation naming ability. Also, it was found that it is appropriate to provid other clues when the defects caused by the degeneration of a specific step during the information processing process become severe.

The purpose of this study was to identify the of patient safety related to perception of Hospital environment, Organizational culture, Reporting system and Factors Influencing on Perception of Medical Errors Report Related to Patient Safety of Healthcare Workers in a General Hospital. Healthcare Workers in a General Hospital in B City who signed on the written consent participated in this study between February 12 and 28, 2017. A total of 244 copies were collected and were analyzed using the SPSS 22.0 program. The result mean score perception of Hospital environment was 3.26(${\pm}0.31$)point on a scale of 0 to 5, and Organizational culture 3.74(${\pm}0.54$)point, Reporting system 3.64(${\pm}0.57$)point. Factors influencing on perception of medical errors report is sex(${\beta}=.137$, p=.023), Type of occupation(${\beta}=289$, p=.001), Department of Nursing(${\beta}=-.196$, p=.023), Hospital environment(${\beta}=.327$, p=<.001), Organizational culture(${\beta}=.288$, p=<.001). Therefore management and hospital management efforts should be made to establish a system that enables healthcare workers to report without fear of medical errors reporting, and appropriate staffing and open communication.
