In this study, a numerical analysis study on the heat transfer characteristics according to the opening and closing of the hydrogen shut-off valve was performed, and the temperature distribution of the key components of the hydrogen shut-off valve was predicted through the result. The ANSYS CFX program was used to predict the heat transfer characteristics of the hydrogen shut-off valve. When the hydrogen shut-off valve was open, the average temperature of the O-ring, which prevents hydrogen leak inside the solenoid valve, was approximately -40℃, and the plunger showed a maximum of -40℃ and a minimum of -110℃. When the hydrogen shut-off valve was completely closed, the O-ring showed approximately 24.82℃ and the plunger showed approximately 24.71℃, which were almost at room temperature.

In this study, the tire FE model was used to predict the shape of the tire, and the change in tire shape was investigated by changing the characteristics of the belt and ply, which are factors that have an important influence on the characteristics of the tire. Tire was modeled and FEM was used to investigate changes in the shape of tires such as overall diameter, tread radius, and section width. The FE model was created and analyzed for 15-inch tire mounted on domestic cars, and it was found that the belt angle was the most sensitive to the shape of the tire, and as the belt angle increased, the overall diameter and tread radius of the tire increased and the tread section width decreased. In addition, it was confirmed that the increase in belt width suppressed the expansion of the tread shoulder, reducing the tread radius, and the belt EPI did not significantly affect the shape change of the tire, and the ply EPI was affecting the change in tire section width.

The blocked force from the electric vehicle compressor is transmitted through the mount to the body side, serving as a primary source of body vibration during air conditioner operation at idle. Accordingly, a method is required during the compressor development stage to quantitatively evaluate the blocked force and analyze its influence for each transmission path. In this study, the blocked force at the outlet of an electric compressor was measured, and a test model was constructed to predict the response of the vehicle body using the Frequency-Based Substructuring(FBS) method. The 6-DOF dynamic stiffness of the bushing up to 500 Hz, not measurable with the elastomer, was successfully obtained using the inverse substructuring(IS) method. Finally, the proposed method was validated by the close match between predicted and measured body vibrations for both conventional and low dynamic stiffness bushings.

Baengnyeong Airport is under review for construction to improve transportation accessibility in island regions and has passed the preliminary feasibility study. While airport development significantly enhances transportation convenience for residents, it may also cause aircraft noise issues and lead to conflicts within local communities. Previous studies estimated noise impacts based on ATR-42 and Q300 aircraft. However, this study focuses on a more realistic assessment using ATR-72 and E190-E2 aircraft. By utilizing the FAA’s Aviation Environmental Design Tool (AEDT), a projected noise contour map for Baengnyeong Airport was developed. The analysis shows that considering ATR-72 and E190-E2, which generate higher noise levels, provides a more practical evaluation of noise-affected areas. The results indicate that the noise impact is mostly confined within the runway area; however, potential noise complaints may arise from Baengnyeong Island and nearby regions. Based on these findings, this study suggests the need for optimized flight procedures and urban planning measures to mitigate aircraft noise issues.

Ride comfort is a key factor in vehicle performance, yet traditional evaluations often rely on subjective methods, leading to inconsistencies. This study presents a deep neural network (DNN)-based model trained on real-world driving data to objectively assess ride comfort. The model’s accuracy is validated using RMS, VDV, and Crest Factor based on ISO 2631. Results show that the DNN effectively captures nonlinear vibration characteristics and offers reliable predictions. This highlights the potential of AI in improving ride comfort assessment.

Since the small screen must be watched at the production and manufacturing site, when using the monitor without a separate paper for work and production instructions, it is necessary to look at the work instruction screen installed in a separate space to prevent work efficiency from deteriorating. It plays a role through a monitoring system using DPS or Barcode and RF-ID recognition as a safety device for installing heterogeneous parts in manufacturing and missing parts, but due to the high cost of introducing the system and difficulty in maintaining management, Visual POP is put into the production line. This study was produced by paying attention to the following five points in order to reduce the weight of these industrial Visual POPs and have global specifications and uses. These include instrument design and design, processing production, UI and control, application, thermal stress analysis and thermal analysis. In this study, it is considered to User Interface and control of Visual POP for two models.

A bolt-fastening method was invented for connecting prefabricated modular structures with a purpose of reducing production cost and enhancing delivery efficiency of precast structures by eliminating welding parts. In order to remove welded connections, a drawing part and a bending part were designed and bolted together to easily generate a long support structure. The bolt-fastened structure had a plate deflection of similar magnitude to that of the welded structure, and weighed about 2.5% less. The heat supplied inside the structure for concrete curing had a negligible effect on the deflection of the structure. Since the unit module is only 640 mm long, and welding is eliminated from production to export local assembly, and the long structure is completed only by fastening, significant reductions in shipping cost and local labor cost are expected.

In this study, we compared and analyzed the influence of the non-face-to-face contact restriction policy due to the COVID-19 pandemic (COVID-19) on the fishing output of two 70-ton offshore trap fishing vessels in Gyeongsangnam-do. Compared to the COVID-19 period, the fishing output increased by about 20% after the end of regulations, but there was almost no significant change in monthly sales. As a result of statistical processing, the unit price of consignment sales per kg showed a significant difference at the p<0.05 level, and there was no difference in variables in the output and monthly sales. It was determined that government support was needed to stabilize the supply of marine products and market prices in preparation for the future post-coronavirus.

ABS engineering plastic materials have excellent corrosion resistance and chemical resistance and are widely used as key materials for improving lightweight and structural performance in automobile interior and exterior materials, aerospace, electronics, and precision machinery industries. Due to these characteristics, as demand also increases, efficient processing methods and attempts to lower processing costs are needed. However, there are many opinions that downward cutting is more advantageous than upward cutting in end mill processing, and research on surface roughness cutting conditions for upward cutting in engineering plastics is insufficient. In this paper, we analyze the effect of upward cutting on surface roughness and present it as basic data for cutting conditions in upward cutting required for industrial sites by providing optimal data for cutting conditions
