Objective: This study examined the gossip, an evaluative conversation about an absent third party, through qualitative research methods, and explored the subjects and the social function of gossip among young children. Methods: The subject of this study included 24 five-year-olds children in Somang class at Baram kindergarten in Seoul. The data consisted of 20 participant observation, 2 in-depth interviews with the teacher, and informal interviews with the children. Results: The subjects of gossip among young children were peers, teachers, and family members. The social function of gossip among children was strengthening peer relationship, selecting peers, confirming rules, and pleasure. The results of this study confirmed that children are sensitive observers of their surroundings and that their peers, teachers, and families are important beings with influence in their lives. It also showed that children's gossip was a social conversation in which children build peer relationships, learn norms and experience pleasant emotions. Conclusion/Implications: This study has the significance of providing various perspectives on the socialization process of young children by looking at gossip which was perceived as a negative image, from a new perspective.

Objectives: We analyzed the reports of philosophical counseling and derived the characteristics of the questions that were administered in philosophical counseling. We also wanted to discuss if philosophical questions are necessary and applicable in Oriental medicine counseling. Methods: A systematic search of three Korean databases were performed. Case reports or case series that apply philosophical counseling to clients were included in this study (through June 27, 2019). We extracted questions and answers from the dialogue of each case. Extracted conversations between counselor and client were analyzed qualitatively. Results: Seven published articles with 17 cases were included and were analyzed for philosophical counseling. Philosophical questions have the following characteristics to help clients: (1) To clarify the phenomenon, (2) To identify subject and object, (3) To consider other people's perspective, (4) To review the premise, (5) To review the association relationship (6) To allow opportunities to think differently, and (7) To think of identity and values. Philosophical counseling and Korean medical counseling have commonalities in improving patients' resilience through logical conversation. The use of philosophical counseling in Korean medical counseling will maximize clients' philosophical resilience and the reparative power of nature. Thus, it is desirable to apply philosophical counseling to the practice of Korean medicine (KM). Conclusions: Through the qualitative analysis, we analyzed and categorized major characteristics of philosophical counseling. In the future, the possibility of using philosophical counseling should be explored in the KM practice.

Recognition of named entity such as proper nouns in conversation sentences is the most fundamental and important field of study for efficient conversational information prediction. The most important part of a task-oriented dialogue system is to recognize what attributes an object in a conversation has. The named entity recognition model carries out recognition of the named entity through the preprocessing, word embedding, and prediction steps for the dialogue sentence. This study aims at using user - defined dictionary in preprocessing stage and finding optimal parameters at word embedding stage for efficient dialogue information prediction. In order to test the designed object name recognition model, we selected the field of daily chemical products and constructed the named entity recognition model that can be applied in the task-oriented dialogue system in the related domain.

Due to the aging of the population, the number of the elderly is increasing, and the nuclear family is rapidly progressing. Today's AI speakers respond to user's commands rather than conversations that occur on a daily basis. If the elderly living alone do not talk first, the usability of the AI speaker will decrease. In this paper, it describes the development of AI speakers for active interaction tailored to the aged. This speaker can identify the movements of the elderly who live alone and their surroundings, actively speak to them, and display emotional expressions appropriate to the content of the conversation. Through this, users will be able to anthropomorphize AI speakers, so they can feel familiarity and emotional conversation is expected to play a positive role in easing their loneliness.

This study developed an English conversation learning program using virtual reality(VR) and mobile devices. Participants learned and practiced English conversational patterns in immersive virtual reality and mobile conditions. In the program, participants learned and practiced nine conversational patterns with virtual characters in four steps. Language anxiety and conversational fluency were measured to examine the effects of this program. Language anxiety questionnaire was administered before and after the experiment. The results showed that language anxiety was significantly reduced after learning in both conditions, and the reduction waa significantly greater in the immersive condition. Conversational fluency was assessed based on the changes in the length, appropriateness, and accuracy of the responses before and after participants learned and practiced conversational episodes. The results showed that the length, appropriateness, and accuracy of the responses were improved in both conditions after learning. The response length was significantly longer in the immersive VR conditions. These results suggest that immersive VR can be an effective tool to enhance English conversational abilities.

This paper sought to find significant learning behavioral indicators and their correlation with the academic achievements of elementary teacher candidates engaged in an online course using MS Teams during the COVID-19 pandemic. Focused on variables such as the number of visiting days to MS Teams, on-time online assignments, conversation activities, posts, and replies, MS Insights data in the LMS environment were collected in the fall term of the 2020 academic year and analyzed in Pearson correlation and multiple regression. The number of visiting days and on-time online assignments were significantly correlated with their grades, whereas the indicators including average weekly conversation activity, posts, and replies did not have a significant effect on the achievements. Furthermore, the results revealed that the subject's behavioral intention to submit on-time assignments significantly predicted learner achievements.

This paper is a study on the relationship of archives and writing. Writing is an big issue these days. Archival studies need to be interested with writings. It's not just about writing skills. Archival studies have to try archiving more good relationships. Symbiotic approach can be worth the efforts. The main focus of this paper is on the writing in archives workshop. Archives workshop is a good place where writing and archiving have a symbiotic relationships. Writing is an archival try to invite the values of 'requests, inquiring after, observes, conversation' to archives. These archival practices can contribute the symbiotic approach to constructed archives.

In this paper, we proposed of the results of the noise level and appropriate conversation distance by applying the noise characteristics generated during treatment at a dental clinic to the NR-curve and PSIL. As a result of analyzing the noise characteristics during treatment at a dental clinic, it was analyzed that the noise level exceeded 60dB(A), which is the health preservation limit value caused by noise, and the noise level increased as the frequency increased. the result of evaluation applying it to the NR curve, some treatment exceeded the workplace noise standard, and as a result of analyzing the level of conversational disturbance between the worker and the patient, it is desirable to have the conversation at a distance of less than 1M for accurate communication. In order to improve the quality of medical service in dental clinic and to reduce dental fear, it is judged that soundproofing protective equipment is provided to workers, and soundproofing measures are needed for noise sources (treatment devices used in treatment) and sound sources (patients and workers).

Recently, research and development using various Artificial Intelligence (AI) technologies are being conducted in the field of education. Among the AI in Education (AIEd), conversational agents are not limited by time and space, and can learn more effectively by combining them with various AI technologies such as voice recognition and translation. This paper conducted a trend analysis on platforms that have a large number of users and used conversational agents for English learning among commercialized application. Currently commercialized educational platforms using conversational agent through trend analysis has several limitations and problems. To analyze specific problems and limitations, a comparative experiment was conducted with the latest pre-trained large-capacity dialogue model. Sensibleness and Specificity Average (SSA) human evaluation was conducted to evaluate conversational human-likeness. Based on the experiment, this paper propose the need for trained with large-capacity parameters dialogue models, educational data, and information retrieval functions for effective English conversation learning.

Currently, droplet protective screens (DPSs) are used to prevent the spread of respiratory diseases. As virus particles can maintain their infective in indoor environments, recent studies have investigated the risk of airborne transmission. However, the ability of DPSs to block airborne transmission has not been verified yet. In this study, the preventive ability of DPSs against droplet and airborne transmission was evaluated. Moreover, the effectiveness of a Portable air purifier (PAP) was investigated. According to results, in a simulated room where an infectious person spoke, the DPS blocked more than 90% of the micron-sized droplets (with a diameter larger than 1 ㎛) transmitted to the front of the infectious person. However, sub-micron droplets (with a diameter smaller than 1 ㎛) passed through the DPS and spread in a room. However, the PAP reduced the amount of both micron and sub-micron droplets transmitted to the front of the infectious person. When the PAP airflow direction was set from the DPS surface to the free space near the infectious person, improved prevention against droplet and airborne transmission was recorded. However, airborne transmission was accelerated when the PAP airflow direction was set from the free space to the DPS surface.
