KAERI is developing the Advanced Spent Fuel Conditioning Process (ACP) as a pre-disposal treatment process for spent fuel. In this process, the management process must operate in intense radiation fields as well as in a high temperature. Therefore, remote maintenance has played a significant role in this process. Hence suitable remote handling and maintenance technology needs to be developed along with the design of the process concepts. To do this, we developed the digital mockup for the ACP. The digital mockup provides the capability of verifying the remote operability of the process without fabrication of the process equipment. In other words, by applying virtual reality to the remote maintenance operation, a remote operation task can be simulated in the digital mockup. Through utilizing this graphic simulation in this digital mockup, general guidelines can be established for designing equipment intended for remote handling and maintenance. Also, the designer of the equipment that must be remotely maintained should ensure that there is adequate access to the process equipment. The graphic simulator will substantially reduce the cost of the develo363pment of the remote handling and maintenance procedure as well as the process equipment.

Digital therapy has emerged as a novel treatment modality, propelled by advancements in information and communication technology. In the last five years, there has been a substantial surge in research publications addressing digital therapeutics (DTx) interventions, signaling a sustained upward trajectory in this field. The dynamic nature of computer science, marked by continuous innovation and development, underscores the need for agile adaptation to rapid changes. Consequently, computer science education is compelled to offer students insights into the latest trends. This research endeavors to contribute to the evolving landscape by developing textbooks that impart knowledge about DTx, an integration of information technology. The study focuses on the application of these textbooks to elementary and middle school students in South Korea. The instructional materials have been carefully organized to enable students to learn about the principle of Attention Deficit Hyperactivity Disorder (ADHD) DTx at the elementary level and the DTx that can prevent and address the digital drama at the middle school level. Based on the application of the textbook, students who received instruction using the textbook showed statistically significant improvements in all subcategories of creative problem-solving ability, including idea modification, visualization, task focus, analogy, idea generation, and elaboration (p<.01). Additionally, there were statistically significant changes in students' self-efficacy before and after using the textbook, with negative efficacy decreasing, and positive efficacy and social efficacy increasing (p<.001).

This research was a descriptive study to investigate the effects of nursing students' biomedical ethics, and critical thinking on attitudes toward withdrawal of life-sustaining treatment. The Participant were 367 nursing students and date were collected from November until December of 2017. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression with SPSS/WIN 21.0. There was a significant positive correlation between attitudes toward withdrawal of life-sustaining treatment. Also, the influencing factor on attitudes toward withdrawal of life-sustaining treatment were biomedical ethics, academic grade, subjective health status, and personality types. These factors explained 36.6% of variance. In conclusion, the higher the awareness of biomedical ethics, the more positive attitude toward the withdrawal of lifelong treatment. Based on the results above, we need to develop diverse and systematic educational programs for nursing students.

As the effectiveness of ionic water that mainly used for the purpose of treatment has been widely known with the recent "well-being" trend, people's interest in it is also gradually increasing. Especially, the alkaline ionic water for drinking purpose could conveniently provide different types/amount of inorganics required for different dietary life depending on nature and race, could effectively provide alkaline inorganics that could be insufficient to modern Korean people, and also could provide alkaline inorganics that prevent/cure/relieve pregnant women's morning sickness. Applying the suggested performance/manufacturing method of alkaline ionic water through the performance assessment of alkaline electrolytic ionic water of the developed product, it would be necessary to have additional researches on the improvement of product or parallel development that could be applied to diverse areas.

This study is a qualitative study applying phenomenological methodology to understand the experiences of childrens with precocious puberty and to describe the whole meaning. Participants were randomly selected from six childrens who had been diagnosed with precocious puberty. From October 12, 2016 to November 18, 2016, data were collected through in-depth interviews with individuals and group interviews. The method proposed by Colaizzi (1978) was used to guide the process of data analysis. Four theme clusters were derived from interview data : the treatment chosen by the mother, uncomfortable treatment, illness not understood well, and don't want to get treatment again. we identified the various emotional and psychological difficulties experienced by childrens with precocious puberty. Future research should develop a nursing intervention program to reduce the burden of the children and accept the treatment as a positive emotion.

Objective: To investigate the three-dimensional lip vermilion changes after extraction and non-extraction orthodontic treatment in female adult patients and explore the correlation between lip vermilion changes and incisor changes. Methods: Forty-seven young female adult patients were enrolled in this study (skeletal Class III patients were excluded), including 34 lip-protruding patients treated by extraction of four first premolars (18 patients requiring mini-implants for maximum anchorage control and 16 patients without mini-implants) and 13 patients requiring non-extraction treatment. Nine angles, seven distances, and the surface area of the lip vermilion were measured by using pre- and post-treatment three-dimensional facial scans. Linear and angular measurements of incisors were performed on lateral cephalograms. Results: There were no significant changes in the vermilion measurements in the non-extraction group. The vermilion angle, vermilion height, central bow angle, height/width ratio, and vermilion surface area decreased significantly after the orthodontic treatment in the extraction groups, but the upper/lower vermilion proportion remained unchanged. Significant correlations were found between the changes in incisor position and those in vermilion angles, vermilion height, and surface area. Conclusions: Extraction of the four first premolars probably produced an aesthetic improvement in lip vermilion morphology. However, the upper/lower vermilion proportion remained unchanged. The variations in the vermilion were closely related to incisor changes, especially the upper incisor inclination changes.

Long-term use of inappropriate prosthesis often results in habitual closure or irregular mandibular movements. In that case, guide to the stable centric position is difficult. Therefore, by using a treatment denture, the muscles and TMJ should be stabilized and the jaw relation should be acquired with the treatment position. Compared to the conventional method, digital technology in fabrication complete denture has the advantage of reproducing a stable tooth arrangement in cases of difficult tooth alignment, minimizing laboratory errors and reducing denture fabrication time. Therefore, in this case, the final denture was fabricated by digitally reproducing the stable treatment position, vertical dimension, and lip support with a treatment denture, and satisfactory results were obtained.
