Flipped classroom (FC) has gained attention as an active learning approach. Designing effective out-of-class activities to help prepare students for in-class activities is fundamental for successful implementation of FC. This study investigated the effectiveness of Goal-Based Scenarios (GBS) for out-of-class learning in FC. Four out of twelve units in a medical humanities course for Year 2 medical students was redesigned into a FC format, where e-learning modules were designed using a GBS approach for out-of-class activities and classroom debates were implemented for in-class activities. The other eight units were delivered in a conventional classroom debate format, which included reading text materials as pre-class assignments. A formative evaluation study was conducted using questionnaires and interview methods and students' academic achievements were evaluated by comparing their pre- and post-test scores between FC and conventional units. Students had positive perceptions of the e-learning modules in GBS approach and preferred the structure of learning in the FC format. Students' pre-test scores were slightly higher in the FC units, yet their post-test scores were comparable with conventional units. This study illustrates students' perceptions that the learning was bettered structured in FC and that the out-of-class learning using the GBS approach helped them better prepared for in-class activities.

In this study, we embark on a journey to uncover the essence of emotions by exploring the depths of transfer learning on three pre-trained transformer models. Our quest to classify five emotions culminates in discovering the KLUE (Korean Language Understanding Evaluation)-BERT (Bidirectional Encoder Representations from Transformers) model, which is the most exceptional among its peers. Our analysis of F1 scores attests to its superior learning and generalization abilities on the experimental data. To delve deeper into the mystery behind its success, we employ the powerful SHAP (Shapley Additive Explanations) method to unravel the intricacies of the KLUE-BERT model. The findings of our investigation are presented with a mesmerizing text plot visualization, which serves as a window into the model's soul. This approach enables us to grasp the impact of individual tokens on emotion classification and provides irrefutable, visually appealing evidence to support the predictions of the KLUE-BERT model.

Objectives : This paper studies the Tangaek-Unhoei(湯液韻彙) index of herbal medicine in the Inje-Ji(仁濟志) of the Imwon-Gyeongje-Ji(林園經濟志), which contains about 4,800 formulas. Created by 19th-century Joseon scholar Seo, Yugu, it not only lists the formulas according to their names, but also provides index by topic, which enabled the collection and effective application of massive medical information. Methods : We quantitatively examined the nearly 4,800 herbal medicines in the Tangaek-Unhoei and their categorization. Any uncommon or particular categorization was examined further by analyzing the original text. Results & Conclusions : The prescriptions contained in the Inje-Ji are categorized under 26 headings. They are listed according to the 106 units of the Chinese character dictionary and organized by double headings. This unique index makes it easy to browse the contents of such a vast book containing massive medicinal knowledge. In addition, the fifty or so remedies called 'Fang(方)' exemplify the author's attitude toward medicinal knowledge, which is both rational and inclusive. This is an attitude that should be recognized beyond tradition.

In this study, we delve into the effects of personalization algorithms on the creation of "filter bubbles," which can isolate individuals intellectually by reinforcing their pre-existing biases, particularly through personalized Google searches. By setting up accounts with distinct ideological learnings-progressive and conservative-and employing deep neural networks to simulate user interactions, we quantitatively confirmed the existence of filter bubbles. Our investigation extends to the deployment of an LSTM model designed to assess political orientation in text, enabling us to bias accounts deliberately and monitor their increasing ideological inclinations. We observed politically biased search results appearing over time in searches through biased accounts. Additionally, the political bias of the accounts continued to increase. These results provide numerical evidence for the existence of filter bubbles and demonstrate that these bubbles exert a greater influence on search results over time. Moreover, we explored potential solutions to mitigate the influence of filter bubbles, proposing methods to promote a more diverse and inclusive information ecosystem. Our findings underscore the significance of filter bubbles in shaping users' access to information and highlight the urgency of addressing this issue to prevent further political polarization and media habit entrenchment. Through this research, we contribute to a broader understanding of the challenges posed by personalized digital environments and offer insights into strategies that can help alleviate the risks of intellectual isolation caused by filter bubbles.

As Damyang has preserved both beautiful natural environment and tradition very well, it needs colors which can coexist with Damyang while preserving it as it is rather than colorful and refined colors. However, the present Damyang deteriorates the quality of beautiful natural scenes by chaotic uses of colors. Therefore, colors which can represent symbolism based on the present colors of Damyang should be used so that everyone can be pleased with them. Finally, the basic colors decided were classified into main, supplement and highlight colors in consideration of characteristics of each scene and they were effectively arranged based on the colors decided. If such colors and color schemes are properly applied according to characteristics of scenes, ecological, historical, cultural and traditional scenes of Damyang can be preserved consistently. Academic literature uses the abstract to succinctly communicate complex research. An abstract may act as a stand-alone entity instead of a full paper. As such, an abstract is used by many organizations as the basis for selecting research that is proposed for presentation in the form of a poster, platform/oral presentation or workshop presentation at an academic conference. Most literature database search engines index only abstracts rather than providing the entire text of the paper. Full texts of scientific papers must often be purchased because of copyright and/or publisher fees and therefore the abstract is a significant selling point for the reprint or electronic version of the full-text. Abstracts are protected under copyright law just as any other form of written speech is protected. However, publishers of scientific articles invariably make abstracts publicly available, even when the article itself is protected by a toll barrier. For example, articles in the biomedical literature are available publicly from medline which is accessible through design. It is a common misconception that the abstracts in medline provide sufficient information for medical practitioners, students, scholars and patients. The abstract can convey the main results and conclusions of a scientific article but the full text article must be consulted for details of the methodology.

As an advance in medical technology development is being made, and people are increasingly aware of the importance of health, related investments and people's average life expectancy rise, which in turn leads to an increase in elderly people. Also, with a growing number of elderly people enjoying their leisure activities, the utilization of multimedia contents using computers is on the increase, leading to an activated research into the establishment of digital culture for the elderly people. This paper proposes a Korean text input system to enable the elderly to utilize digital contents. Text input interface has conventionally depended on keyboards. However, the keyboard wherein many keys are dispersed creates problems for the elderly, such as a protracted recognition of keys and a lowered concentration when they use the keyboard. To address these problems, in this paper, the grip type controller interface for console games was used and a corresponding alphabet location algorithm was developed. To verify these efforts, a simulator was developed to test 20 elderly people; as a result, their satisfaction over and convenience of using the grip type interface increased.

This paper suggested MyeonGu(面垢), symptom of Baekho-tang(白虎湯) in text 219 of Shang-Han-Lun(傷寒論), could be reinterpreted. There were 4 cases, 1 case on atopic dermatitis and 3 cases on psoriasis. All of them were diagnosed by Ying-Ming-Bing(陽明病) symptom. After taking Baekho-tang, SCORAD index of atopic dermatitis in case 1 improved 62.8 to 12.8 and PASI score of psoriasis in case 2, 3, and 4 improved 13.0 to 2.4, 10.8 to 0.8, and 8.6 to 1.0 respectively. Since Baekho-tang was effective for certain skin disease with Ying-Ming-Bing(陽明病) symptom, MyeonGu could be related on skin problem. MyeonGu was mainly translated in 'someone's face seems to be covered with dirt'. However if Myeon(面) is translated in 'surface of the body' and Gu(垢) is translated in 'inflammation', it means the surface of the body suffered from papules, erythema, white scales, etc. These are features of chronic inflammatory cutaneous disease like atopic dermatitis and psoriasis. This study is meaningful in case of giving specific clinical case of MyeonGu of Baekhotang text of Shanghanlun.

Purpose : This Study was conducted to evaluate clinical manifestations of abdominal pain(AP) in childhood according to its symptoms and to find out characteristic of children with abdominal pain. Methods : Pacients who visited Dong-Eui Oriental Medical hospital from August to November 2001 due to abdominal pain were included. According to questionaire and history taking abdominal pain was classified by its six subtype in the Oriental Pediatic Text Book and Dong Eui Bo Gam(東醫寶鑑). Result : According to the Oriental Pediatic Text Book, among 41 children, 31.7% had symptoms of AP caused by cold in internal organs of deficiency(臟腑虛冷腹痛), 29.3% had symptoms of AP caused by diet(食積腹痛), 19.5% had symptoms of AP caused by cold(寒腹痛), 9.8% had symptoms of AP caused by both cold and diet, 7.3% had symptoms of AP caused by internal diet and external cold(內食外寒腹痛), 2.4% had symptoms of AP caused by stagnation of Ki and stasis of blood(氣滯血瘀腹痛). There is no AP caused by parasites(蟲腹痛). Otherwise, according to Dong Eui Bo Gam, 43.9% had symptoms of AP caused by cold, 26.8% had symptoms of AP caused by diet, 9.8% had symptoms of AP caused by both cold and diet, 7.3% had symptoms of AP caused by fire(熱腹痛), 7.3% had symptoms of AP caused by phlegm(痰飮腹痛), 4.9% had symptoms of AP caused by stagnated blood(瘀血腹痛). Also There is no AP caused by parasites. Conclusion : 1. The type of AP in Childhood is different from AP in adults. AP in Childhood is most occured by cold of deficiency and food, and there is few AP caused by fire. Six subtype in Dong Eui Bo Gam prefer adults to children and It is more studied that what kind of subtype is proper for AP caused by stress or drugs. So the study on subclassification and clinical Manifestations of AP in Childhood is more performed.

Recently, the participation, opening and joint ownership of the users are important issue. The users want professional and accurate information from web. But users often suffer from retrieving accurate information. Even though the users find information they want, it is not guaranteed that the information is reliable since there are too much information placed on the web. Thus, we propose the novel rank metric to promote reliability and efficiency in information retrieval. In order to verify our approach, we implement a web site based on the proposed rank metric for nonofficial medical science information. The proposed rank metric based on user's level. This is to give score of text through differential rate depending on the user's level. The proposed rank metric enhances the reliability of text which is reflecting the user's mental factor. Thus, this method can be used for enhancing the reliability of text.
