As the size of the gaming market continues to grow, game engines like Unity and Unreal are constantly being developed and updated for multi-platform support. In particular, Unity divides the Render Pipeline to be used. Among them, the Universal Render Pipeline (URP) has the advantage of supporting various platforms while improving performance by reducing draw calls and batches at the same quality settings and reducing the load on the CPU and GPU. However, only limited global illumination is supported in the real-time 3D rendering area within URP, such as Baked GI and Enlighten GI, and Enlighten GI will be deprecated after 2024LST, so real-time global illumination is not available in URP, which may reduce the realism and immersion of global illumination in games or applications that use URP. The main objective of this research is to incorporate precomputed spherical harmonics into URP to enable dynamic GI updates in real-time. The approach proposed in this research is to compute the coefficients of spherical harmonics offline and then run them within the URP rendering pipeline, where work exists to effectively simulate dynamic lighting conditions. To demonstrate this, experiments were conducted by changing the rotation and color of the lights, and a comparative analysis was performed to demonstrate the effectiveness of the theory proposed in this work.

In the case of nuclear projects, when developing a new reactor type, it is necessary to confirm the reactor type, secure the safety, and especially obtain the construction permit approval of the licensing authority for construction. Schedule management is necessary to carry out nuclear projects, and progress rate management of project progress management is largely composed of three elements: scope management, cost management, and resource management. However, in the case of the small modular reactor (SMR) project currently being carried out, it is difficult to calculate the progress rate including budget and resources due to the nature of the project. Therefore, in the SMR project, it took two years from the beginning to prepare the integrated project master schedule (IPMS) to prepare the draft, and then two revisions were made over a year and a half. In this SMR project, we will consider the entire construction period such as design, purchase and production, construction, commissioning, and operation in terms of scope management. The entire document list was created using the document review and approval sheet created at the beginning of the design. In the PMIS (Project Management Information System), the number of approved documents was calculated by comparing the list of engineering documents. In the purchase production part, the main core equipment such as the primary system nuclear steam supply system (NSSS), the secondary system turbine and condenser, and the man machine interface system (MMIS) are managed. Purchasing and manufacturing management shall be managed so that major equipment can be delivered in a timely manner in accordance with the schedule for delivery of equipment in the IPMS. In order to prevent delays in the start of production, it is necessary to minimize the waiting time for work through advance management tasks such as insurance of drawing, stocking of materials, availability of production facilities, etc. In this way, we decided to carry out the schedule management for the design, purchase and manufacturing part in the SMR project first, and the installation, construction and commissioning part will be prepared for the future schedule management.

초파리를 당뇨병을 연구하는데 사용하는 경우가 많으나 당뇨병이 유전적 요인에 작용하여 다음 세대에 미치 는 영향을 다루고 있는 연구는 적다. 따라서 본 연구에서는 초파리에 고당도의 먹이를 통해 당뇨병을 유발하고, 류신(leucine)의 당뇨병에 대한 치료효과를 확인하고 다음 세대에 미치는 영향을 알아보고자 했다. 본 연구에서 는 Drosophila melanogaster를 초파리 모델에 사용했다. 먹이에 고농도의 설탕, 고농도의 설탕과 류신을 첨가하여 당뇨의 발병과 당뇨병의 치료효과를 확인했다. 당뇨병의 발병을 확인하기 위해 초파리의 체내의 포도당을 측정 하여 대조군에 비해서 고농도의 설탕을 섭취한 경우에 포도당의 농도는 증가했고, 류신을 섭취한 경우에는 포도 당이 대조군에 비해서도 급격히 떨어지는 것을 확인했다. 고농도의 설탕이 포함된 먹이 조건을 유지하고 교배를 통해 자손을 얻고자 하였다. 그 결과, 고농도의 설탕을 섭취한 경우 자손의 몸의 크기가 0.1mm 정도 감소하고 무게 또한 감소했다. 그러나 고농도의 설탕과 류신을 섭취한 경우 자손을 얻지 못했다. 당뇨병을 유발시킨 초파리 를 이용해 류신과 운동의 효과를 동시에 확인했다. 당뇨병이 유발된 경우 운동만으로는 포도당의 감소에 영향을 주지 못하였으나, 류신 운동을 병행한 경우에는 포도당이 감소했고 수컷 초파리에서 잘 관찰되었다. 운동과 류신 섭취를 병행하는 실험에서는 당뇨병을 유발한 초파리의 자손을 사용했기 때문에 크기는 당뇨병을 유발하지 않은 것보다 작았다. 따라서 초파리의 당뇨병 모델을 통해서 당뇨병이 유전적으로 전달되며 Leucine에 의한 치료 는 성충에 수행되는 것이 효과적임을 알 수 있었다.

Essential macleod program (EMP) was used to optimize the transmittance of the transparent conducting layers in an oxidemetal- oxide structure. For EMP simulation, the optical coefficient of the material was extracted using an ellipsometer. Following the simulation studies, oxide-metal-oxide samples were fabricated experimentally, and their optical and electrical properties were analyzed. Multilayer SiInZnO/Ag/Siinzno (S/A/S) structures were grown on glass substrates using radio frequency (RF) and direct current (DC) sputtering at room temperature. Due to the occurrence of destructive interference at the metal and oxide interface, the S/A/S structure exhibited excellent optical properties. As the thickness of the top and bottom oxide layers was increased, the transmittance spectrum was red-shifted due to partial wave interference at the Ag interface. Change in thickness of the top oxide layer had a greater effect on the transmittance than that of the bottom oxide layer. This was due to the difference in refractive index occurring at each interface. Change in Ag thickness shifted the absorption edge in the short wavelength region. Whereas electrical properties, such as sheet resistance and carrier concentration, were found to be dependent on thickness of the sandwiched metal layer. An excellent figure of merit of 63.20 ×10−3Ω−1 was obtained when the thickness of the Ag layer was 11 nm, and the top and bottom oxide layer thickness were 45 and 60 nm, respectively. These values suggest promising optoelectronic properties and are encouraging for future transparent electrode applications.
