In this paper, we develop technology to improve the stability and quality of boat equipment manufacturing through vacuum injection process fusion to increase the safety of boats. Safe mold design and fabrication are carried out to determine the resin flow rate and water flow rate of a boat, and the performance of vacuum maintenance work is guaranteed through the tensile and compressive strength of the manufactured hull and deck. When manufacturing the boat air mechanism (Aerostat), the adhesion between equipment materials and the deformation of the joints are very important factors for safety. Due to the nature of equipment manufacturing, process fusion to minimize manual process minimizes deformation after manufacturing through accurate manufacturing ratio. Accordingly, it is possible to accurately control the mixing ratio of resin and hardener as optimal conditions for boat drying and securing safety, and to convert optimal information into a database by analyzing working conditions over time such as resin flow rate and flow rate, thereby improving durability and quality. Through this, it is expected that production efficiency and safety design will be improved by enabling efficient production process management with a small number of personnel.

In this paper, a metaverse-based safety operation service platform is implemented for safe maintenance and operation of RTO devices. Most RTO systems operating 24 hours a day have limitations in responding immediately to a failure over a long distance, resulting in inefficient maintenance situations. In particular, the aging of field personnel, inexperience in equipment operation, and lack of transition due to the turnover of professional personnel cause many problems in equipment operation. Therefore, long-distance monitoring and safety training are required.A virtual space is constructed based on the metaverse, and the equipment structure, circuit diagram, part characteristics, and detailed configuration are constructed in a 3D shape using digital twin technology. To this end, 3D modeling technology generates a mesh based on the design data of the RTO equipment and generates the texture of the equipment based on the actual picture. Low latency and high-quality data should be provided to multiple users in remote locations. It is delivered to XR devices, PCs, and smartphones to build a 3D virtual space on the site. At this time, the location of the remote user is shared with the site as location data using AR glasses (smartphones). Therefore, monitoring, which was operated as an existing 2D screen, is combined with 3D space to provide an environment and efficiency that can be intuitively and visually recognized.

The term ‘pregnancy-associated breast cancer’ is no longer used as it has been consistently reported that breast cancer during pregnancy and breast cancer after delivery (postpartum breast cancer) have different characteristics and prognosis. The purpose of this study is to define postpartum breast cancer by analyzing the incidence rate, related factors, and prognosis according to the timing of breast cancer. Data from the Korean National Health Insurance Service were used to analyze 1,292,727 women aged 20-49 years who birthed their first child between 2007 and 2012. The annual incidence rate of breast cancer after delivery increased every year (7.7 per 10,000 person-years after 5 years, 19.36 per 10,000 person-years after 10 years). The risk of breast cancer was significantly higher (hazard ratio 1.15, 95% CI 1.05-1.27, P=0.0037) in women diagnosed with gestational diabetes, but that was not associated with overall survival (OS). Patients diagnosed with breast cancer within 5 years of delivery had a poorer prognosis than those diagnosed later (5-year OS, <5 years: 91.1% vs. 5-10 years: 96.0%). In multivariate analysis of OS, the hazard ratio of patients diagnosed within 5 years after delivery was twice as high as of patients diagnosed between 5 and 10 years. Women diagnosed with gestational diabetes had an increased risk of breast cancer. Breast cancer patients diagnosed within 5 years of delivery had a poorer prognosis than those diagnosed later. In this regard, careful screening for early diagnosis of high-risk patients and intensive research on new treatment strategies are needed.

Nam June Paik was a pioneering creator of interactive sound art before he became a cult figure in the field of video art. While Paik gradually developed interactive sound art in West Germany, he wrote several articles about contemporary music in Europe. Specifically, a musique concrète article for Korean readers is significant as a seed of his interactive projects. This study examines the content of the music article and articulates the relationship between musique concrète and Paik’s interactive sound projects: Record Shashlik (1963) and Random Access (1963).

Despite the fact that more breast cancer survivors are currently enjoying longer lifespans, there remains limited knowledge about the factors and issues that are of greatest significance for these survivors, particularly from their perspectives. This review was based on the concept that the topics addressed should focus on the perspectives of current survivors and should be extended to future modalities, which physicians will be able to use to gain a better understanding of the hidden needs of these patients. We intended to choose and review dimensions other than the pathology and the disease process that could have been overlooked during treatment. The eight topics upon which we focused included: delay of treatment and survival outcome; sexual well-being; concerns about childbearing; tailored follow-up; presence of a family history of breast cancer; diet and physical activity for survivors and their families; qualitative approach toward understanding of breast cancer survivorship, and; mobile health care for breast cancer survivors. Through this review, we aimed to examine the present clinical basis of the central issues noted from the survivors' perspectives and suggest a direction for future survivorship-related research.

This paper presents a method of shoal motion with an effective leadership of autonomous virtual fish. Shoal motion is led by a leader and computed by five steering behavior vectors including cohesion, separation, velocity, escape and goal vectors. Through experiments, we demonstrate that a leader of the motion simulation has great effect in leadership and great accuracy to guide the group.
