Due to the increasing influence of the Korean Wave, traditional themes are emerging to the forefront of performance content development, emphasizing the necessity of applying the art of storytelling to the creative process. The purpose of this research is to examine the differentiated costume design of the Pansori ballet "Dokkaeba! Dokkaeba!," developed through the implementation of storytelling in its performance creation process. Choreographers, writers, and costume designer collaborated throughout the storytelling process from planning to content creation. This resulted in a clarified depiction of the Dokkaebi as divine beings with transcendental powers who are simultaneously friendly and familiar entities, often appearing in the form of humans and objects. Accordingly, the costume design based on this collaborative storytelling deliberately avoided the appearance of Dokkaebi reminiscent of 'Kwimyeonwa' or Japanese 'Oni', typically expressed with horns or decorations, and instead implemented novel design elements, such as fusion Hanbok with a variety of dimensionally aesthetic accessories, meaningful color contrast in modern clothing, textural elements indirectly expressing character and transmogrification, and daily clothing attire to illustrate the humanized Dokkaebi. Therefore, this study seeks to contribute to the production of new performance art showcasing the Dokkaebi by identifying the diversity of expression and direction within costume design.

Purpose: This study was performed to find the current problems of PET/CT data from other hospitals. Materials and Methods: The subjects were acquired from 64 hospitals referred to our department for image interpretation. The formats and contents of PET/CT data were reviewed and the phone questionnaire survey about these were performed. Results: PET/CT data from 39 of 64 hospitals (61%) included all transaxial CT and PET images with DICOM (Digital Imaging Communications in Medicine) standard format which were required for authentic interpretation. PET/CT data from the others included only secondary capture images or fusion PET/CT images. Conclusion: The majority of hospitals provided limited PET/CT data which could be inadequate for accurate interpretation and clinical decision making. It is necessary to standardize the format of PET/CT data to transfer including all transaxial CT and PET images with DICOM standard format.

We designed a borehole deviation survey tool applicable for steel-cased holes, K-DEV, and developed a prototype for a depth of 500 m aiming to development of own equipment required to secure deep subsurface characterization technologies. K-DEV is equipped with sensors that provide digital output with verified high performance; moreover, it is also compatible with logging winch systems used in Korea. The K-DEV prototype has a nonmagnetic stainless steel housing with an outer diameter of 48.3 mm, which has been tested in the laboratory for water resistance up to 20 MPa and for durability by running into a 1-km deep borehole. We confirmed the operational stability and data repeatability of the prototype by constantly logging up and down to the depth of 600 m. A high-precision micro-electro-mechanical system (MEMS) gyroscope was used for the K-DEV prototype as the gyro sensor, which is crucial for azimuth determination in cased holes. Additionally, we devised an accurate trajectory survey algorithm by employing Unscented Kalman filtering and data fusion for optimization. The borehole test with K-DEV and a commercial logging tool produced sufficiently similar results. Furthermore, the issue of error accumulation due to drift over time of the MEMS gyro was successfully overcome by compensating with stationary measurements for the same attitude at the wellhead before and after logging, as demonstrated by the nearly identical result to the open hole. We believe that the methodology of K-DEV development and operational stability, as well as the data reliability of the prototype, were confirmed through these test applications.
