Purpose This study aims to identify the factors that negatively affect the perceived usefulness of ChatGPT and their impact on perceived usefulness. Furthermore, this study aims to investigate whether AI literacy can reduce the degree of influence in the relationship between negative factors and perceived usefulness. Design/methodology/approach In this study, we surveyed users aged 20 or older who have been using ChatGPT for at least 3 months. A total of 191 questionnaires were distributed and collected for analysis. To test the hypotheses, path analysis and multiple group analysis were performed. Findings Privacy, limited comprehension, and hallucination were found to have a negative impact on perceived usefulness, while cost risk had no effect. AI literacy was also found to moderate in the relationships between privacy and perceived usefulness and between limited comprehension and perceived usefulness.

This study investigated differences in children's story comprehension as they related to the types of reading media. The participants comprised 62 four-years-olds from two child-care centers located in a middle-income region of Seoul and Gyeonggi Province. In order to control the experience effect, newly developed stories published into two formats of reading media (paperback books and electronic books) were provided to the participants. The results indicated that there were no significant differences in children's story comprehension depending on the types of reading media. Paperback book readers and electronic book readers did not show any significant difference in story comprehension, which consists of recall, recognition and reasoning tasks. As literature pertaining to children's usage of electronic books is limited, the present study offers guidelines for the development of children's reading media and may serve as a useful resource for future studies.

본 논문은 인식론적인 측면에서 디지털 인터페이스의 새로운 가능성을 확인하는데 그 목적이 있다. 우선 디지털 인터페이스의 역사를 개관함으로써 현재의 인터페이스가 우연적 계기들의 산물임을 밝히고 있다. 그것이 필연적인 결과가 아니라는 사실은 새로운 디지털 인터페이스가 무한히 존재할 수 있음을 암묵적으로 증언한다. 현실의 제한된 인터페이스는 디지털 기술과 디지털 미디어에 대한 제한적 이해로부터 파생하였다. '블랙박스'라는 은유를 통한 이해가 바로 그것이다. 본 논문은 디지털을 일종의 빛으로 보는 사유를 통해 이러한 이해를 극복하고 있다. 빛으로서의 디지털과 디지털 미디어라는 새로운 인식론은 인터페이스 디자인 활동이 차이를 긍정하고 생성하는 창조적 활동으로 나아가야 한다는 윤리학으로 발전한다.

The purpose of the present study was to investigate the effectiveness of reciprocal teaching procedure for improving Korean college students' reading comprehension of English text. In particular, this study sought to explore the qualitative features, if any, in students' use of reading comprehension strategies presented in the process of Reciprocal Reading Procedure (RRP). In order to accomplish the goal of the study, transcripts of the students' dialogues, open-ended questionnaires, and researchers' observation notes were examined. The results of the study showed that the participants used different four kinds of reading strategies in the process of RRP (questioning, clarifying, predicting, summarizing). The findings also suggested that the readers with limited knowledge of vocabulary had difficulty in moving on to the next level. Additionally, future research direction and some pedagogical implications are presented for the practical EFL classroom.

Object : The purpose of this study is to understand age-related maculardegeneration(AMD) with both western and Korean medicine.Methods : We investigated the comprehension of general AMD degenation in both western and Korean medicine through literature review.Results : The results are as follows.1. AMD prevalent increasing as the population ages; however, treatment options remain limited and incompletely defined.2. Generally macular degeneration has been affected by aging and is associate with the function of kidney(腎) and liver(肝) in Korean medicine.Conclusion : Further studies are needed to apply comprehension of AMD in Korean medicine to clinical stage.

In the legislation interpretation and fundamental viewpoint about the legal system of insider trading, Japan strictly legislate under the proposition, the principle of 'nulla poena,' adopted 'the principle of limited enumeration,' and United states, under 'the principle of comprehension,' has entrusted courts with establishment of concrete concepts and standard, so the courts are very flexible in determining the range of insiders and the importance of inside information to show a strong will to eradicate insider trading. Korea has a legislative position of 'the principle of limited indication' which has been created by the negotiation between those principles of United states and Japan. Though this court has interpreted insider trading, insider trading using non-disclosed information has increased lately, needing the strengthening of its regulations. However, this shows us that sophisticate the regulations may be, the exposure of insider trading has limitations. The most important thing is to change recognition for transparency of the securities market, security of investors and to establish the atmosphere which is that fair stock trading made in a sound capital market to raise funds for corporation. The policies of improving unfair trading, self-regulation bodies, raising the transparency and legality of procedures of supervision and monitoring and applying 'compliance program' to stock companies are very needed to eliminate unfair trading in the securities market and establish the order of trading.

Eddy current induction is used in a wide range of electronic devices, for example in detection sensors. Due to the advances in computer hardware and software, the need for 3D computation and system comprehension is a requirement to develop and optimize such devices nowadays. Pure theoretical models are mostly limited to special cases. On the other hand, the classical use of commercial Finite Element (FE) electromagnetic 3D models is not computationally efficient and lacks modeling flexibility or robustness. The proposed approach focuses on: (1) implementing theoretical formulations in 3D (FE) model of a detection device as well as (2) an automatic Volumetric Estimation Method (VEM) developed to selectively model the target finite elements. Due to these two approaches, this model is suitable for parametric studies and optimization of the number, location, shape, and size of PCB receivers in order to get the desired target discrimination information preserving high accuracy with tenfold reduction in computation time compared to commercial FE software.

The purpose of this study is comprehension for relationships between job stress and mental health for dental technicians in performing their duties. and this study can make use of opportunity of accumulation of data on dental technician's health care and work environment in future. Job stress for dental technicians served in general hospital dental laboratory were more highly effected than in local dental laboratory. and this result was statistically reliable. There were no meaningful differences in mental health between dental technician in dental laboratory in dental climic dental laboratory and commercial dental laboratory. and this result was not statistically reliable. The analysis of this study could be used by preliminary data to further research of relationships between job stress and mental health for dental technicians in the future. This study was made progress partially under limited members of dental technician in Seoul. so future studies are suggested that the more advanced total figure study for whole dental technicians in Korea.

Reading fluency is an important variable in reading comprehension. However, a limited number of studies on reading fluency are available in Korea. The purpose of this study is to review the articles about reading fluency during last 10 years and to present a direction for future research. Forty research papers from the Journal of Learning Disabilities and Language Speech and Hearing Services in Schools were selected from 2002 to 2012. These papers were analyzed in terms of their subjects and research methods. About 64% of the articles focused on typically developing children and children with dyslexia. About 67% of the research consisted of descriptive studies. Based on these results, suggestions were made for future research on reading fluency.

어휘 학습은 영어 학습에 있어 기반이 되는 매우 중요한 요소임에도 불구하고, 실제 학교 현장에서는 문법이나 독해 등 다른 요소에 비해 중요하게 다루어지지 못하고 있는 실정이다. 또한, 영어학습을 위한 인터넷 사이트들도 많이 제공되고 있지만, 이들 사이트에서 조차도 어휘 학습보다는 문법이나, 구문. 독해 등에 그 초점이 맞추어져 있는 경우가 대부분이고 어휘학습을 위한 기능제공은 극히 제한적임을 볼 수 있었다. 이에 본 연구에서는, 한정된 수업시간 내에 이루어지기 어려운 영어어휘 학습을 수업전이나 후에 학습자 스스로 수행 할 수 있도록 하기 위해 웹 기반의 어휘학습 보조 시스템을 설계, 구현하였다. 이 시스템은 학습자가 스스로 문맥을 통한 어휘학습을 수행할 수 있도록 해 주며, 어렵거나 새로운 어휘를 반복 학습하는데 효과적인 학습구조를 갖추고 있다.
