A comprehension-based approach to learning assumes that incoming information and background knowledge are integrated to form a mental representation which is subsequently used to incorporate new knowledge. It is demonstrated that this approach can be validated by comparing human and computational model performance in the prompt learning context. A computational model (ADAPT-UNIX) based on the construction-integration theory of comprehension (Kintsch, 1988; 1998) predicted how users learn from help prompts which are designed to assist UNIX composite command production. In addition, the comparison also revealed high similarity in composite production task performance between model and human. Educational implications of present research are discussed on the basis of the fact that prompt instructions have differential effect on learning and application as background knowledge varies.

Information skill, which means information technology skill and information handling skill, is related to the aims and processes of higher education as a knowledge creation activity. In this study, a curriculum design is proposed for the development of the information literate student. The framework of this curriculum derives form the US Information literacy standards for higher education 2000, the UK Information skills in higher education 2004, and Australian and New Zealand Information literacy framework 2004. The teaching plan and content is based on the information literacy programs of NMSU, CSU Hayward, and IUE. It is proposed that the development of the idea of information literacy requires a collaborative and integrated approach to curriculum design and delivery based on investigation of user's satisfaction with the curriculum.

Doors are to be the most basics of our lives from opening, closing and even keeping our property. Hence, doors have been innovated to blend in and make our daily lives more convenient. However, we find it difficult to open and close the doors manually of offices or tour zones, where they open and close at a precise time everyday. To solve this, we added a dimension of time to previous Door Locks. By this, every door with this specific door lock will open and close at a certain time we want them to open or close. Also, through the application you can control the time or use it to open and close the doors remotely. In order to do this, we systemed the door lock time system based on Java Programing language to make it easy to communicate and open or close the doors through smart phone applications, with the C programming language for the ATmega128 which will open and close the doors.

Implicit citation sentence recognition is to locate citation sentences which lacks explicit citation markers, from articles' full-text. State-of-the-art approaches exploit word ngrams, clue words, researcher's surnames, mentions of previous methods, and distance relative to nearest explicit citation sentences, etc., reaching over 50% performance. However, most previous works have been conducted on English. As for Korean, a rule-based method using positive/negative clue patterns was reported to attain the performance of 42%, requiring further improvement. This study attempted to learn to recognize implicit citation sentences from Korean literatures' full-text using Korean lexical features. Different lexical feature units such as Eojeol, morpheme, and Eumjeol were evaluated to determine proper lexical features for Korean implicit citation sentence recognition. In addition, lexical features were combined with the position features representing backward/forward proximities to explicit citation sentences, improving the performance up to over 50%.

Statistics on the occurrence of fires in residential facilities over the past 10 years, show that approximately 40% are fires in apartment buildings. To prevent the spread of fire and support evacuation in apartment housing, the fire resistance performance and performance design of fire doors are becoming more important. This study established a database using 395 quality inspection reports from 2016 to 2020, which passed the fire performance test, and derived the fire door performance-influencing factors through an analysis of the structure (12 elements) of the fire door. As a result, the effect of core material, adhesive, hinge type, blowing agent, etc. was confirmed in 287 pass cases. On the other hand, it was confirmed that the occurrence of flames and crevices in the 108 cases of failure were the major failure factors in the fire door fire resistance test. Fire doors are composed of composite materials to prevent failure of fire resistance performance, and efficient design and quality control are required through standardization of components.

After COVID-19, communication through online platforms has increased, leading to an accumulation of massive amounts of conversational text data. With the growing importance of summarizing this text data to extract meaningful information, there has been active research on deep learning-based abstractive summarization. However, conversational data, compared to structured texts like news articles, often contains missing or transformed information, necessitating consideration from multiple perspectives due to its unique characteristics. In particular, vocabulary omissions and unrelated expressions in the conversation can hinder effective summarization. Therefore, in this study, we restructured by considering the characteristics of Korean conversational data, fine-tuning a pre-trained text summarization model based on KoBART, and improved conversation data summary perfomance through a refining operation to remove redundant elements from the summary. By restructuring the sentences based on the order of utterances and extracting a central speaker, we combined methods to restructure the conversation around them. As a result, there was about a 4 point improvement in the Rouge-1 score. This study has demonstrated the significance of our conversation restructuring approach, which considers the characteristics of dialogue, in enhancing Korean conversation summarization performance.

Background: Leakage, stricture formation, and tumor recurrence at the anastomotic site are serious problems after esophagectomy for cancer of the esophagus or cardia. The prevalence of these postoperative complications may be affected by whether an anastomosis is made in the neck or in the chest, therefore a comparison was made between anastomoses made at these two sites. Material and Method: Between 1987 and 1998, 36 patients with cancer of the esophagus underwent transthoracic esophagectomy with cervical(NA, n=20) or thoracic anastomosis(CA, n=16). The tumors were staged postoperatively(stage IIA, n=13; s tage IIB, n=7; stage III, n=16) and were located in the middle thoracic(n=22) or lower thoracic esophagus and cardia(n=14). Result: The overall operative mortality was 8.3%(5% for NA group, 12.5% for CA group). The anastomotic leak rate for the NA group was 15.0% and 12.5% for the CA group. The anastomotic leak rate differed according to the manual(27.3%) or stapled(8.0%) techniques(p < 0.05). The median proximal resection margins in the NA and CA groups were 9.6 cm and 5.8 cm, and the corresponding rates of anastomotic tumor recurrence were 5.3% and 28.6%(p < 0.05). The prevalence of benign stricture formation (defined as moderate/severe dysphagia) was higher in the NA group(36.8%) than in the CA group(21.4%). When an anastomosis was made by the stapled technique, smaller size of the staple increased the prevalence of stricture formation - 41.7% with 25-mm staple and 9.1% with 28-mm staple(p < 0.05). Conclusion: Wider resection margin could decrease the anastomotic tumor recurrence, and the stapled technique could decrease the anastomotic leak. The prevalence of benign stricture was higher in the cervical anastomosis but the anastomotic leak and smaller size(25-mm) of the staple should be considered as risk factors.
