Purpose : This study aimed to determine the experiences of the disaster response team 9 participants who participated in the disaster after the fire incident occurred in Jecheon Sports Center and their meaning and essence. Methods : Nine disaster response teams were the subjects of the study, and Individual in-depth interviews were conducted. Data were collected online between January 6 and April 30, 2021, from the software Zoom^TM. This study was conducted as a qualitative study by applying Giorgi's phenomenological experiential research method, which has an advantage in revealing the essential structure and meaning of experience. Results : Three major themes were derived from the study results: the stimulus through unfamiliar experiences, the grievances due to work environment and regional characteristics, and dullness resulting from hiding and enduring. The following 17 sub-themes were identified: learning through unfamiliar experiences, frustration due to unexpected circumstances, shock from unfamiliar experiences, doing my best in the present, confidence due to increased experience, disunified system, intervention of various interests, the atmosphere that puts responsibility on others, inactive help, unforgettable regional characteristics, working without time to settle, tolerating it in my own way, memories left in the unconsciousness, sudden suffering from memories that come to mind, movement in anxiety and tension, dullness, work with colleagues in the same situation. Conclusion : This study is meaningful in that it attempted to provide basic data in preparing a long-term strategy for effective policy direction and institutional protection based on the systematic mental health management of the disaster response team. Additionally, this study's results can be used as primary data for future research among Disaster Response Team.

In this paper, we design and implement an online exhibition application based on an Android platform that can showcase the artistic works of disabled artists. This application considers user convenience for disabled artists, particularly providing STT(Speech-to-Text) and TTS(Text-to-Speech) features for visually and hearing impaired individuals. Additionally, for the exhibition of works by disabled artists, the application implements disability certification during registration using disability certificates and registration numbers, ensuring that only authenticated disabled artists can exhibit their works. The database storing personal information of disabled artists and information about art pieces is implemented using MySQL. The server module utilizes RestAPI to transmit data in Json format. To address the large data size of art piece information, it is stored using Firebase Storage, eliminating data size limitations on the server. This application can alleviate issues such as a lack of exhibition space for disabled artists and a lack of communication with the general public.

This paper proposes a new real-time fire monitoring and evacuation navigation system by integrating Augmented Reality (AR) technology with Internet of Things (IoT) technology. The proposed system collects temperature data through IoT temperature measurement devices installed in buildings and automatically transmits it to a MySQL cloud database via an IoT platform, enabling real-time and accurate data monitoring. Subsequently, the real-time IoT data is visualized on a 3D building model generated through Building Information Modeling (BIM), and the model is represented in the real world using AR technology, allowing intuitive identification of the fire origin. Furthermore, by utilizing Vuforia engine's Device Tracking and Area Targets features, the system tracks the user's real-time location and employs an enhanced A^* algorithm to find the optimal evacuation route among multiple exits. The paper evaluates the proposed system's practicality and demonstrates its effectiveness in rapid and safe evacuation through user experiments based on various virtual fire scenarios.

In this paper we study a nudging continuous data assimilation algorithm for the three-dimensional Leray-α model, where measurement errors are represented by stochastic noise. First, we show that the stochastic data assimilation equations are well-posed. Then we provide explicit conditions on the observation density (resolution) and the relaxation (nudging) parameter which guarantee explicit asymptotic bounds, as the time tends to infinity, on the error between the approximate solution and the actual solution which is corresponding to these measurements, in terms of the variance of the noise in the measurements.

Purpose: To evaluate the effects of a logotherapy program entitled 'Finding meaning in my life' for adolescents with terminal cancer. Methods: A nonequivalent control group, non-synchronized design was conducted with a convenience sample of 44 late adolescents with terminal cancer. The experimental group (n=22) participated in the 'Finding meaning in my life' program which consisted of five-day sessions for one week. The control group (n=22) received the usual nursing care. The effects were measured using adolescent meaning in life (AMIL), and quality of life (QOL) scales. The collected data were analyzed by descriptive statistics, Chi-square, and t-test using SPSS/PC 17.0 program. Results: There were significant differences in AMIL (t=3.36, p<.05) and QOL (t=2.67, p<.05) between the experimental and control groups. Conclusion: Logotherapy is effective in improving the meaning in life and quality of life of late adolescents with terminal cancer, and can be used to prevent existential distress.

The main purpose of this study was to provide understanding of the meaning of post menopausal womens' lived body changing experience. The methodological approach was guided by Van Manen's hermeneutic phenomenological methodology : inquiring and investigating experience as it was lived rather than as conceptualized : reflecting and analyzing the essential themes which characterize the phenomenon : and describing the phenomenon through the art of writing and rewriting. Multiple strategies for data collecting were used ; in depth face-to-face interview ; analysis of womens' writings : artistic work : and analysis of examples of phenomenon in art, literature, and drama. Although the experience was different for all of the women interviewed, essential themes of experience emerged ; Drifting through the years (solitude, in the twilight of life, loneliness, change of taste, forgetfulness, the sense of missing something), A walking weather forecast, Standing on the threshold of losing ki energy, Lately taking care of my body, Seized with fear all of a sudden, Keenly feeling the preciousness of life, Preferring comfortableness to prettiness, Wanting to recall my past years, A strong impulse to rechallenge life, Becoming more fond of friends. Findings from the artistic and creative inquiry further validated the interview findings and the meaning discovered. The study illuminated meaning and simultaneously validated the phenomenological research process. Essential themes for understanding women's experience, implications for education, research, and practice, direction and need for continuing inquiry were identified.

While a lot of comparisons of DBMS performance for processing large scale database are given as results of bench-mark tests, there are few comparisons of DBMS performance for processing small scale database. Therefore, in this study, we compared and analyzed on the performance of commercial DBMS and public DBMS for small scale database. Analysis results show that while Oracle has low performance on the operations of update and insert due to the overhead of rollback for data safety, MySQL and MS-SQL have good performance without additional overhead.
