This study aimed to examine the recent Hanbok school uniform design directions to contribute to the distribution of Hanbok school uniforms and the accumulation of Hanbok-inspired fashion design sources. We reviewed 16 academic papers published on Hanbok school uniform designs from 1998 to 2023 and summarized the design features proposed therein. We also analyzed 172 items of Hanbok school uniform designs developed under the Hanbok school uniform promotion project hosted by the Hanbok Advancement Center between 2019 and 2022. We found that the recent Hanbok school uniform design characteristics conformed to the design directions proposed in previous studies in terms of line, color, fabric, and textile pattern. Conforming design characteristics include the following. Overall, silhouettes were straight and moderately fitting to the body. Detailed straight and curved lines from Hanbok were applied. Designs showed traditional Hanbok colors, including white, black, and navy. Machine washable cotton and various blended fabrics were used. Modernized traditional patterns such as Saekdong, cloud, and Gwae were applied to textile designs. In contrast, some characteristics of recent designs deviated from the proposed design directions. Barrel silhouettes were found in casual styles of uniform items, including sweatshirts, hoodies, and jumpers. A wider range of materials, including fleece, quilted fabric, brocade, and Jinju silk, were used. Uniforms had looser silhouettes and were made with modern washable materials to meet students’ preference for casual uniforms.

Transition-metal phosphides (TMPs), a promising anode material for lithium-ion batteries (LIBs), are limited in application because of its serious volume effect in the cycle. In this work, a simple electrospinning strategy was proposed to restrict the grain size of CoP nanocrystals by nano-confined effect of carbon nanofibers with ligands. The addition of ligands not only could realize the uniform dispersion of CoP nanocrystals, but also strengthen the bond between the metals and carbon nanofibers. As a result, the CoP/CNF composite exhibits excellent lithium storage performance, and its reversible specific capacity could reach 1016.4 mAh g− 1 after 200 cycles at a current density of 200 mA g− 1. The research is anticipated to provide a new idea for the preparation of anode materials for lithium ion batteries.

Various electronic control parts and devices installed in electric vehicles have greatly improved the convenience of occupants, but electromagnetic waves emitted from electronic devices have greatly increased concerns about malfunctions, deterioration of performance, safety accidents, etc. There are two models of analysis. Case A is symmetrical about one axis of rotation. Case B has two axes of rotation. In this study, a flow analysis was conducted to find excellent flow conditions in the mixing process to develop a paint with excellent electromagnetic shielding and thermal insulation performance. The results of the flow analysis are reflected in manufacturing specifications and are intended to be used to develop high-quality systems.

In this experiment, the engine (i30 FD) was fabricated and installed in front of the intake manifold of the gasoline engine of the 2010 1,600cc MPI(Multi Point Injection) 4-cylinder 16-valve DOHC(Double Over Head Camshaft) electronic control fuel injection system, and the plenum chamber was 150cc, 300cc, 4. The engine rotation speed was increased from 1000rpm to 3000rpm by 500rpm, and the pressure change and engine volume efficiency change of the air intake manifold runner were analyzed. In this study, the volume of air flowing into the cylinder was maximized through the stabilization of pressure vibration in the intake manifold runner part due to the engine operation condition and the volume change of the intake manifold plenum chamber, and the uniform distribution rate of the intake air was confirmed by minimizing the interference between the cylinders. It has in the purpose to analyze the flow characteristic at the intake manifold inside. It can apply to obtain the optimal design factor.

This study is a development of a system for measuring the surface resistance of wafer and LCD by utilizing a three-axis positioner. Previous wafer measuring system is a developed product for measuring a wafer surface resistance. This is developed very long time. This is not a real action that it is needed a persistence development.. So, that is effected as weak point by simple mechanism and old software. This product is forecasted not being risen in world market. Therefore, this new product(surface measuring system by three axis positioner type) through this research is off the point a previous one axis revolute type, this new product is forecasted capable of a measurement not only wafer but also LCD.

This paper presents accelerated life tests for Type I censoring data under probabilistic stresses. Probabilistic stress, Sj, is the random variable for stress influenced by test environments, test equipments, sampling devices and use conditions. The hazard rate, ,thetaj, is the random variable of environments and the function of probabilistic stress. Also it is assumed that the general stress distribution is uniform, the life distribution for the given hazard rate, θ, is exponential and inverse power law model holds. In this paper, we obtained maximum likelihood estimators of model parameters and the mean life in use stress condition.
