The aim of this study is to provide the background of developing guides to clinical performance and basic clinical skills and to introduce how to teach and learn using the guide. The students' performance problems presented in an objective clinical skills examination were disease-centered tertiary hospital clinical care, incomplete performance, doing by rote, and an exam-oriented learning attitude. The problems were caused by a tertiary hospital-based educational environment as well as schools and faculty who are unfamiliar with the concept of patient-centered care. The purpose of the guide to clinical performance and basic clinical skills is to overcome these problems and address the causes. The guides show a clinical presentation approach to primary care; clinical care integrated with knowledge, skills, and attitude; a schematic approach; and a patient-centered attitude. To achieve these goals, a strategy to change the educational culture is important. Curricular reform, faculty development, and improving educational facilities and environments are suggested.

Style is considered a pivotal construct in sociolinguistic variation studies. While previous studies have examined style in traditional forms of language such as speech, very little research has examined new and emerging styles such as computer-mediated discourse. Thus, the present study attempts to investigate style in the online communication mode of chat. In so doing, the study compares text-based online chat with speech and writing. Online chat has been previously described as a hybrid form of language that is close to speech. Here, the exact nature of online chat is elucidated by focusing on contraction use. Differential acquisition of stylistic variation is also examined according to English learning background. The empirical component consists of data from Korean speakers of English. Data is taken from a written summary, an oral interview, and a text-based online chat session. A multivariate analysis was conducted. Results indicate that online chat is indeed a hybrid form that is difficult to delineate from speech and writing. Text-based online chat shows a somewhat similar rate of contraction to speech, which confirms its hybridity.. Lastly, some implications of the study are given in terms of the learning and acquisition of style in general and in online contextual modes.

This study aims to build a model is capable of classifying the categories of hadith, according to the reliability of hadith' narrators (sahih, hassan, da'if, maudu) and according to what was attributed to the Prophet Muhammad (saying, doing, describing, reporting ) using the supervised learning algorithms, with a view to discover a relationship between these classifications, based on the outputs of this model, which might be useful to avoid the controversy and useless debate on automatic classifications of hadith, using some of the statistical methods such as chi-square, information gain and association rules. The experimental results showed that there is a relation between these classifications, most of Sahih hadiths are belong to saying class, and most of maudu hadiths are belong to reporting class. Also the best classifier had given high accuracy was MultinomialNB, it achieved higher accuracy reached up to 0.9708 %, for his ability to process high dimensional problems and identifying the most important features that are relevant to target data in training stage. Followed by LinearSVC classifier, reached up to 0.9655, and finally, KNeighborsClassifier reached up to 0.9644.

The field of facial expression recognition (FER) has been actively researched to improve human-computer interaction. In recent years, deep learning techniques have gained popularity for addressing FER, with numerous studies proposing end-to-end frameworks that stack or widen significant convolutional neural network layers. While this has led to improved performance, it has also resulted in larger model sizes and longer inference times. To overcome this challenge, our work introduces a novel lightweight model architecture. The architecture incorporates three key factors: Depth-wise Separable Convolution, Residual Block, and Attention Modules. By doing so, we aim to strike a balance between model size, inference speed, and accuracy in FER tasks. Through extensive experimentation on popular benchmark FER datasets, our proposed method has demonstrated promising results. Notably, it stands out due to its substantial reduction in parameter count and faster inference time, while maintaining accuracy levels comparable to other lightweight models discussed in the existing literature.

언어학습 도구로서 스마트폰은 강의실 밖과 비교했을 때 수업시간에 활용되는 경우는 흔하지 않다. 따라서 본 연구의 목적은 영어 듣기의 수업 활동에서 스마트폰의 유용성을 파악하는 것이다. 71명의 학생들이 한 학기 동안 Practical English Listening and Reading 과목에서 개별적으로 스마트폰을 이용하여 듣기 활동을 하였다. 학기 말에 학생들은 스마트폰 활동에 관한 10문항의 설문에 응답하였다. 설문을 분석한 결과 스마트폰을 이용한 듣기 활동은 학생들의 영어 듣기에 대한 흥미를 유발하였으며 개인별 맞춤 학습으로서 듣기 능력을 향상시키는 효과를 가져왔다. 그런데 스마트폰이 지닌 다른 기능들이 학생들의 듣기 활동을 방해한다는 사실이 스마트폰 활용의 가장 큰 단점으로 나타났다. 이를 해결하기 위해 듣기 활동을 모두 스마트폰 활동으로 할 것이 아니라 강의실 컴퓨터를 사용한 전체 활동도 병행할 것을 제안한다. 학생들이 원하는 혼합율은 50대 50 이었다. 학생 집단의 수준에 따라 그 혼합율은 달라질 수 있을 것이다. 이러한 연구결과는 디지털 융합 영어학습을 활성화하는데 기여할 것이다.

The purpose of this study was investigated the perceptions and expectations of science gifted elementary students in the laboratory-based science learning. For the purpose of this study, semi-structured interviews were conducted with 20 science gifted elementary students in J city. The question of the interview is constructed with perception and expectation of science gifted elementary students in divided with 4steps of understanding of lesson object, planning experiment, performing experiment and drawing conclusion in laboratory-based science learning and an attitude for science. The interview is progressed per individual and all the content of the interview is recorded. The result of this research is as follows. The science gifted elementary students have a wish for building an assumption and expectation and planning an experiment with discussion more than following the textbook and teacher present. In the step of the experiment, they wanted general more discussion of their own activities rather than teacher's instruction and they wanted teacher's instruction and they wanted teacher's mediation conflicts within small groups and comments for students' experiment results. The science gifted elementary students wish to open a science lab, which man who likes science can go and come freely and to study with friends who have a same interest to make a theme. And from top to bottom they want to test autonomous and ask to salute like a representative experiment of teacher. And they ask to have a chance to test individually and want to see a movie related to an experiment before doing an experiment. Like this, it presents that the scientifically gifted elementary students want to do an experiment what they can, want to have a class which can plan and can do an experiment by themselves through discussion with the unit more than following explanation of a teacher and a textbook without condition.

To introduce an emissions trading system for GHG that currently have no reduction requirements, the following should be considered as priorities: eliciting the participation of the industrial sector and linking GHG emission trading systems to the emissions trading system (implemented from July 2007) that has become part of national policy with the enactment of the Special Act. Two directions can serve as viable alternatives in that regard. One is a baseline-and-credit method based on incentive auctioning. This has the advantage of inducing participation through economic incentives without a reductions commitment. The downside of this method is that it requires vast investments, as well as the fact that reaching an agreement between participants and the government to decide an objective baseline is difficult. On the other hand, the cap-and-trade method set forth in the Special Act is attractive in that it can be integrated with the air pollutant emissions trading system, but it would be difficult to elicit the participation of the industrial sector in the absence of GHG emission reduction requirements. In the current situation, it would be preferable for the government to induce the participation of the industrial sector by devising a wide variety of incentives because taking part in the emissions trading system before reducing GHG emissions offers large incentives through learning by doing. The timing of GHG reduction commitments and emissions trading system implementation may be uncertain but their Implementation will be unavoidable. Thus the government needs to facilitate preparations for emissions trading of GHG in the future and continuously review its operation in integration with the air pollutant emissions trading system to maximize adaptation and teaming by doing effect in the industrial sector.
