Previous studies on English spelling have investigated the types of spelling errors and their frequencies, and studies on why learners made those errors have been called for. This study aimed to identify factors leading to errors in the English-spelling of Korean elementary school students. The factors were investigated by using the following methods: A total of 130 students from O Elementary School were given three types of word-writing tasks: dictation of single words, dictation of short sentences, and writing words as many as the students can based on pictures depicting familiar scenes. The errors in their writing samples were classified into five types. The students were interviewed about why they made those errors. The results showed that the errors were influenced by the factors: the students’ first language, background knowledge, pronunciation, and morphological reasons. The results suggest that if teachers understood these factors, they would be able to explore better teaching methods for reducing errors in English spelling, and that future research could apply these factors for further investigations.

We aimed to develop and analyze the effectiveness of a “Room of Errors” simulation program for educating nursing students in patient safety management. Methods: This study used a quasi-experimental method (two group, before and after evaluation) and enrolled 35 nursing students as the participants. Data were collected using a self-reported questionnaire and analyzed through descriptive statistics and the independent t-test and Mann-Whitney U test using SPSS/WIN Statistics version 25.0. Results: After completing the “Room of Errors” simulation program, the participants’ score of intention and confidence in performance for patient safety management in the experimental group were significantly higher than those in the control group. Conclusion: A “Room of Errors” simulation education program for nursing students effectively increased the intention and confidence in performance of nursing students in patient safety management.

According to the ROK-IAEA Comprehensive Safeguards Agreement (CSA), the ROK submits inventory change reports (ICRs), physical inventory lists (PILs), and material balance reports (MBRs). Suppose inventory changes occur in each material balance area (MBA). In that case, the facility operators prepare ICRs monthly, conduct physical inventory taking (PIT) every 12 to 18 months, and submit PILs and MBRs to KINAC. KINAC reviews ICR presented by the facility operators, submits it to the IAEA, and reports it to the Nuclear Safety and Security Commission (NSSC). Various methods have been prepared and implemented to minimize errors in reviewing the accounting reports submitted by the facility operators. Accordingly, this paper analyzes the mistakes in the accounting reports that occurred over the past two years and proposed methods to improve them. The basis for carrying out the accounting reports is stipulated mainly in the CSA and the Nuclear Safety Act. First, Article 63 of the CSA describes the rationale for submitting the accounting reports, and the details are described in detail in the subsidiary arrangement. Article 98 of the Nuclear Safety Act stipulates information related to accounting reports, and details are described in the regulations on reporting internationally regulated materials, etc., of the NSSC Notice No. 2017-84. Among the accounting reports submitted in 2021, a total of 36 errors were confirmed. There were ten errors related to inventory changes, followed by six errors in the material balance period (MBP) in the header information. There were four cases of spacing, weight mismatch, and overdue errors, and the rest were related to grammar errors. There were a total of 30 errors in the accounting reports identified in 2022. MBP errors of header information, which occurred the second most in 2021, was the highest with nine, followed by six inventory change errors and five weight mismatch and overdue errors, respectively. Compared to 2021, the total number of errors has decreased by about six, which is interpreted as the result of outreach activities through accounting reporting workshops and nuclear control education conducted by KINAC. Accounting reporting is the most critical part of the Nuclear Material Accounting and Control (NMAC) system. Efforts to check errors in accounting reports and improve report quality through outreach activities could be confirmed by the statistics of the two years analyzed earlier. In the future, if the reporting program used by the facility operators is improved to minimize errors and manage the accounting reporting system through continuous maintenance work, the quality of the accounting reports will be upgraded to the next level.

Background: Korea citation index (KCI) enhances the quality of journals by securing a management system for domestic journals and strengthening the international competitiveness of excellent domestic journals. Errors in studies, papers, and investigations of statistical methods have been reported worldwide in the medical field. However, there is a lack of studies on statistical methods and error investigations in physical therapy journals in Korea. Objectives: To investigated the frequency of statistical methods and research errors in physical therapy journal articles evaluated by KCI. Design: Review. Methods: Ten journals classified as physical therapy journals by December 2021, which are candidate journals or higher, were targeted. The study focused on original articles published from 2017 to 2021 and investigated the frequency of statistical methods used, sample size calculations, result tables, effect sizes, and confidence intervals. Results: Statistical methods used in physical therapy studies in Korean journals mainly employed group comparative analysis. However, in most cases, the basis for sampling, effect size, and confidence interval were not presented, even though most of the results tables were included. Conclusion: This study allowed us to examine the most frequently used statistical methods in Korean physical therapy studies and assess the reporting status of sample size calculations, result tables, effect sizes, and confidence intervals. Efforts are needed to publish high-quality papers to improve the quality of Korean physical therapy journals.

Purpose: Room of Errors is a little-known method in Korea, effective for patient safety education. This study aimed to examine nursing students’ recognition of pre-staged medical errors while working as individuals or in a team. Methods: Thirty-four errors for a pre-op care scenario and thirty errors for a post-op care scenario were pre-set in two simulated patient rooms. Fifty-six nursing students randomly participated as individuals or as a team in one of two “Room of Errors” to find as many errors as possible within a certain time. The evaluation of error detection and debriefing occurred immediately following the simulation. Results: “Wrong patient name on wrist band” (77-100%) and “bedside rails down” (91-100%) were the most frequently identified errors by both individuals and teams. Few students found “injection of a drug to which the patient is allergic” (0-9%) and “administration of a contraindicated drug to the patient” (0-7.7%). The performance of students working in a team was much better than those working alone. Conclusion: This study found that “Room of Errors” provided very experiential and practical learning to nursing students in identifying simulated patient threats. The method is also useful for interprofessional patient safety education to develop teamwork and communication.

Yi Qie Jing Yin Yi written by Xuan Ying of the Tang Dynasty is a model work of the sound and meaning of Buddhist sutras. At present, two collated editions have been published, but there are still many errors that have not been corrected. These errors can be divided into three types: primary errors, secondary version errors and other kinds of errors. Primary errors are annotation errors caused by the limitations of the author’s own knowledge; The secondary version errors refer to the errors added in the spreading of the book. Other kinds of errors are the errors that we can not determine whether they belong to the primary errors or secondary version errors according to the existing materials. Based on this classification, this paper lists several errors that were not reached by predecessors in the previous practice, in order to seek advice from others.

The present study aims to categorize common word choice errors in Korean EFL writing and help teachers understand students’ word choice patterns. This study reassures that both L1 and its background cultures affect language learners’ choice of vocabulary in English learning. Korean first-year undergraduate students with low levels of English proficiency participated in this study. The students were required to carry out a writing log, a collection of nine pieces of weekly assignments of paragraph writing during the semester. They were allowed to use any type of automatic translation such as Google Translate or Papago for revision and editing. The errors that the students produced were classified into three categories, and significant findings were obtained regarding lexical errors caused by literal translation, cultural differences, and L1 word order. The findings are interpreted in terms of cultural and linguistic differences between the first and target languages. They can give ideas for teachers to instruct EFL writing strategies on students’ word choice errors.

To investigate L2 adolescent learners’ use of machine translation (MT), an MT error correction (EC) test was developed, based on the analysis of MT errors arising from translating the learners’ L1 of middle school EFL textbooks. Learners were also asked to report on their use of MT EC strategies on the EC task. Results indicated that mistranslated sentence and verb tense are the most difficult types of MT errors to correct. Furthermore, to resolve MT errors, guessing from context and literal translations were the two most frequently employed EC strategies. When multiple regression analysis was conducted to examine the contribution of EC strategies to the learners’ ability to correct errors, the mid proficiency learners’ reliance on literal translations and the low proficiency learners’ use of multiple EC strategies were positively associated with improved corrections of MT errors. The results of the study are discussed in light of how L2 learners need to develop competence for using MT in L2 writing.

Since the Korean pronoun system does not specify gender indication, Korean speakers of English tend to have difficulties when they use English pronouns. This paper explores how absence of obligatory gender marking in Korean affects gender errors in the production of English. Gender pronoun errors made by Korean learners of English were analyzed using recordings of English conversations of seven Korean subjects. Findings of this study revealed that Korean English learners struggled with the use of gender pronouns due to differences in gender pronoun systems between Korean and English. Both gender-neutrality and pro-drop practices do not require Korean speakers to pay close attention to gender factors when using pronouns in their native language, resulting in native language interference. Considering that the Korean language lacks specific gender orientation in its usage of pronouns whereas English requires clear gender specification, findings of this study imply that native language gender concept can influence second language use.

Este trabajo analiza los errores debidos a la interferencia coreana al escribir/traducir al español. Sostenemos que, cuando los alumnos ingresan una vez en la memoria una forma española α que corresponde preferentemente a una forma coreana A, tienden a equiparar esta correspondencia como ‘A = α’ y la aplican a los casos en los que dicha correspondencia no debería usarse. Para averiguar cuántos alumnos cometen este tipo de error, realizamos un experimento con 42 alumnos. En el experimento, dividimos las oraciones en dos grupos. Las oraciones que pueden producir un resultado apropiado se colocaron en el grupo A si usamos la correspondencia ‘A → α’, mientras que las que pueden producir un resultado inapropiado se ubicaron en el grupo B si lo hacemos. Nuestro análisis mostró que el error más común del grupo B es reutilizar la correspondencia utilizada en el grupo A. Por lo tanto, los estudiantes necesitan evitar una “ecuación excesiva” para reducir errores. Finalmente, para cada oración, sugerimos formas de reducir o evitar errores.

The purpose of this study is to examine phonetically if the spelling errors produced by foreign Korean learners are related to learners’ pronunciation by analyzing the pronunciation of plain, tense, and aspiration sounds of foreign Korean learners using a Praat. A statistical analysis was performed on the listening, reading, and writing data produced by 18 foreign university students at the beginner level. The results are summarized as follows. First, foreign Korean learners accounted for the majority of errors in plain and aspiration sound among initial obstruent words. This can be interpreted as an extremely strong or very weak pronunciation of the word, because learners do not properly recognize the intensity of range in plain sounds. Second, the more accurate the learner’s perception was, the more accurate production can be made. Statistically, it was found that the production rate increased by 0.178 each time the perception rate increased by 1. Therefore, the correlation between perception and production is established. Third, the relationship between pronunciation and spelling is a relationship that increases by 0.652 each time the pronunciation increases by 1. It can be explained that there is a possibility that the learner may often write words as they pronounce them.

목적 : 본 연구는 동공크기 변화에 따른 굴절이상과 고위수차를 노안 전후의 연령군으로 분류하고 비교 분석하여 노안 처방 등의 임상에 도움이 될 수 있는 정보를 제공하고자 한다. 방법 : 안질환 및 굴절교정 수술을 받은 경험이 없는 20세~80세의 성인 남녀를 20~40세 그룹과 45~80세 두 그 룹으로 나누어 굴절이상과 고위수차를 측정하였다. 동공크기 변화에 따른 굴절이상과 고위수차의 비교는 Paired-T test를 이용하였고, 연령에 따른 상관분석은 Pearson correlation으로 실시하였다. 결과 : 20~40세 대상자의 등가구면 굴절력은 동공크기 3 mm에서 –3.193±2.494 D, 5 mm에서 –3.386±2.451 D로 0.193 D 근시도가 증가하였으며, 45~80세 대상자의 등가구면 굴절력은 동공크기 3 mm에서 0.015±1.340 D, 5 mm에서 –0.054±1.566 D로 0.069 D 근시도가 증가하였다. 또한 동공크기 3 mm에서 20~40세 대상자보다 45~80세 대상자의 코마수차는 0.026 μm, 구면수차는 0.016 μm, 트레포일수차는 0.037 μm, 비점수차는 0.012 μ m, 콰트레포일수차는 0.022 μm 증가하였다. 결론 : 노안교정을 위한 누진굴절력렌즈 처방 시 시력을 저하시킬 수 있는 동공크기나 고위수차를 참고하여 처 방해야 할 것으로 생각된다.

인공지능은 학습, 추론, 판단, 이해, 행동 등 인간의 지적 능력의 일부 또는 전체가 컴퓨터 프로그램을 통하여 구현된 것을 말한다. 따라서 소프트웨어가 매우 중요하다고 할 것이다. 그럼에도 불구하고 인공지능의 소프트웨어와 관련하여서는 많은 연구가 이루어지지 않고 있다. 지원이 종료된 운영체제가 적용된 인공지능을 사용하다가 사고가 나는 것을 방지하기 위하여 운영체제의 지원이 종료되기 전 최신 운영체제로 업데이트해주는 것이 필요하다. 이러한 자동업데이트가 가능하도록 하기 위해서는 사전에 소비자에게 자동업데이트에 관한 동의를 얻어야 한다. 이러한 동의는 자유롭게 이루어져야하며, 구체적이고, 충분한 정보를 제공받았어야 하며, 명백한 표시여야 한다. 또한 이러한 자동 업데이트를 위한 동의는 사전에 포괄적으로 이루어질 수밖에 없을 것으로 보이고, 이러한 방식으로 동의를 얻는 것은 ‘약관’에 해당한다고 할 수 있다. 따라서 약관법의 적용을 받는다. 뿐만 아니라 소프트웨어의 안전을 위하여 지속적인 업데이트는 필요하기 때문에 자동업데이트에 반대한 경우라도 업데이트가 있을 때마다 개별적인 동의를 받는 등의 해결방법이 필요할 것으로 보인다. 만약 개별적인 동의를 얻는 과정에서 업데이트를 거부하여 업그레이드되지 않은 소프트웨어의 오류로 인하여 인공지능 등이 손해를 발생시키는 경우 그 손해에 대한 배상책임은 소유자가 지도록 하는 것이 타당하다. 제조자가 업데이트를 하지 않는 경우 소비자가 매도인에게 하자담보책임에 기하여 업데이트를 청구할 수는 있다. 그러나 단순 매매만을 한 매도인에게 업데이트를 청구하는 것은 바람직하지 않고, 소프트웨어에 관하여 가장 잘 알고 있는 것이 제조업자이기 때문에 제조업자에게 업데이트를 청구하는 것이 가장 바람직할 것이다. 그러나 인공지능의 소프트웨어는 이제 막 발전하고 있는 단계로 제조업자가 제조물을 공급한 당시의 과학·기술 수준으로는 결함의 존재를 발견할 수 없었다는 이른바 ‘개발위험의 항변’을 주장할 가능성이 크다. 이러한 점에서 더욱이 제조물관찰의무의 필요성이 대두된다. 그러나 우리나라의 제조물책임법은 제조물관찰의무 위반의 효과에 관해서만 규정하고 있을 뿐 의무의 이행방법에 관하여는 규정하고 있지 않다. 따라서 이러한 부분의 구체화가 필요할 것으로 보인다. 따라서 적극적 제조물관찰의무의 구체적인 이행방법에 관한 규정이 필요할 것으로 보이고, 이러한 적극적 제조물관찰의무의 이행 방법으로 설계의 변경과 회수의무의 법제화가 필요할 것으로 보인다. 또한 제조물책임법은 무과실책임을 그 원칙으로 하고 있어 제조자에게 큰 부담을 지우고 있다. 게다가 전술한 바와 같이 제조물관찰의무의 이행방법 중 하나인 회수의무와 설계의 변경을 의무화하는 경우 그 부담은 더욱 커질 것으로 보인다. 이러한 부담은 결국 제조물 즉, 인공지능의 가격을 높이게 만들 것이며 이는 소비자의 부담으로 이어질 것이다. 이러한 문제를 해결하기 위하여 제조물배상책임보험의 의무화가 필요하다.

There has been a significant decline in the number of rail accidents in Korea since system safety management activities were introduced. Nonetheless, analyzing and preventing human error-related accidents is still an important issue in railway industry. As a railway system is increasingly automated and intelligent, the mechanism and process of an accident occurrence are more and more complicated. It is now essential to consider a variety of factors and their intricate interactions in the analysis of rail accidents. However, it has proved that traditional accident models and methods based on a linear cause-effect relationship are inadequate to analyze and to assess accidents in complex systems such as railway systems. In order to supplement the limitations of traditional safety methods, recently some systemic safety models and methods have been developed. Of those, FRAM(Functional Resonance Analysis Method) has been recognized as one of the most useful methods for analyzing accidents in complex systems. It reflects the concepts of performance adjustment and performance variability in a system, which are fundamental to understanding the processes of an accident in complex systems. This study aims to apply FRAM to the analysis of a rail accident involving human errors, which occurred recently in South Korea. Through the application of FRAM, we found that it can be a useful alternative to traditional methods in the analysis and assessment of accidents in complex systems. In addition, it was also found that FRAM can help analysts understand the interactions between functional elements of a system in a systematic manner.
