This study examines how interactivity and usage mode of a chatbot interface affects user experience. Chatbot has rapidly been commercialized in accordance with improvements in artificial intelligence and natural language processing. However, most of the researches have focused on the technical aspect to improve the performance of chatbots, and it is necessary to study user experience on a chatbot interface. In this article, we investigated how 'interactivity' of an interface and the 'usage mode' referring to situations of a user affect the satisfaction, flow, and perceived usefulness of a chatbot for exploring user experience. As the result, first, the higher level of interactivity, the higher user experience. Second, usage mode showed interaction effect with interactivity on flow, although it didn't show the main effect. In specific, when interactivity is high in usage mode, flow was the highest rather than other conditions. Thus, for designing better chatbot interfaces, it should be considered to increase the degree of interactivity, and for users to achieve a goal easily through various functions with high interactivity.

The present study intends to understand how multimodality can be implemented in a content course curriculum and how students perceive multimodal tasks. Twenty-eight students majoring in English were engaged in a digital storytelling assignment as a part of the content curriculum. Findings from the questionnaire and reflective essays that investigated students perceptions of digital storytelling showed that students felt that the assignment helped them engage in the task and felt motivated. In comparison to traditional writing tasks, students perceived digital storytelling to be more engaging and motivating, but felt that the assignment required more mental effort and caused more anxiety. By supporting students to explore technology and implement multimodal aspects in the learning process, digital storytelling can encourage engagement and autonomous learning to create meaningful works that are purposeful and enjoyable.

The setting of the target area for ground stability evaluation during ground excavation is categorized into theoretical and empirical estimation methods and numerical analysis methods. Generally, the applied theoretical and empirical estimation methods include those by Peck (1969), Caspe (1966), and Clough et al. (1990). The numerical analysis method comprehensively considered the current status of the task section (maximum excavation depth section, ground condition vulnerable section, etc.). It reflected the results of performing two and three-dimensional numerical analyses on the weakest section. Therefore, this study shows an example of setting the scope of influence when excavating the vertical and tunnel sections of a 000-line double-track private investment project through the above theoretical, empirical, and numerical analysis methods.

This study explored the lexical sophistication features to distinguish the group membership of English proficiency, using the automatic analysis program of lexical sophistication. A total of 600 essays written by 300 Korean college students were extracted from the ICNALE (International Corpus Network of Asian Learners of English) corpus and a discriminant function analysis was performed using SPSS program. Results showed that the lexical features to distinguish three groups of English proficiency are SUBTLEXUS frequency content words, age of acquisition content words, lexical decision mean reaction time function words, and hypernymy verbs. High-level Korean students used frequent content words from SUBTLEXUS corpus to a lesser degree and produced more sophisticated words that can be learned at a later age and take longer reaction time in lexical decision task, and more concrete verbs.

하천단면이나 하상변동 추적 등 하천공간정보는 유량이나 강우 등 수문시계열 정보와 더불어 계획홍수위 산정이나 하천구조물 신설로 인한 하천의 변화를 추적하는 데 있어 근간을 이루는 주요 정보로 국가차원의 유지 및 관리가 필요하다. 국내의 하천공간정보는 RIMGIS, WAMIS, 하천 일람, WINS와 같은 웹기반 시스템에서 정보화 되어 관리되고 있다. 그러나, RIMGIS는 여러 가지 문제점을 노정하고 있어 개선을 적극적으로 검토해볼 시점이라고 볼 있다. 우선, RIMGIS는 구축이 10년 이상된 기술로 구성되어 온라인 시스템 실행속도가 느리고, 물관리 일원화 와중에 관리주체가 불분명해진 상태이며, 제공되는 정보도 하천망이나 유역 정도로 차원 및 정확도도 낮고 활용도 및 현행화도 부족한 상태이다. 또한 공간정보 관리 DB표준으로 효율적인 관계형 구조 대신 하천대장 등을 수치화한 개념의 레이어 단위의 주제도로 관리하다보니 자료중복이 불가피하여 시스템이 무겁고, 자료간 연관검색이 거의 불가하고, 신속한 하천지형 변화 업데이트가 어려운 상태이다. 최근 진행되고 있는 RIMGIS 개선 사업은 여전히 종래의 레이어 단위의 주제도들을 추가하거나 개정하는 데 머물고 있는 상태이다. 이러다 보니 현재 우리나라의 대표적인 하천정보시스템인 RIMGIS의 실무 활용도는 낮은 것으로 알려져 있다. 가장 실무활용도를 저하시키고 현행화 상의 문제로 지적되는 부분은 하천정비기본계획 수립 시 발생한 공간자료 관리 부실이다. 현재 RIMGIS에서는 하천기본계획보고서만 PDF 형태로 제공할 뿐, 실제 지형자료는 과업을 수행한 설계사에 개별 보관되어 활용도뿐만아니라 망실의 우려가 높은 상황이다. 본 연구에서는 하천기본계획수립 시 측량되는 단면을 포함한 다양한 공간자료를 관계형으로 표준화 DB에 효율적으로 저장할 수 있게 하는 방안을 제시하고자 한다.
