The Republican Period of China (1912 to 1949) was when the archetypes of thought (constituting contemporary China) engaged in heated rivalry and were directly influenced by Korea through frequent exchanges. This study analyzes the characteristic of Chinese women's aesthetics towards the human body with a focus on visual materials (such as articles and illustrations concerning hairstyle, makeup, skincare, fashion, and gymnastics) featured in the Chinese women magazines of Fun$\ddot{u}$zazhi (婦女雜誌) and Linglong (玲瓏). This study analyzes these magazines and compares them with Korean counterparts. The movement of the developed and controlled human body was a common characteristic of this period; however, compared to the Chinese, the Japanese colonial period of Korea resulted in an introspective self-examination through excessively objectified eyes. Dress and adornment as the symbol of a new civilization acted as the most remarkable signifier. The overlapping of a western image with a Japanese image led to more resistance in Korea. The criterion for the value of a women's external appearance (that traditionally dualized womanly virtues) collapsed and dress was accepted as an expression of individuality instead of as a social class. The human body was traditionally recognized as a microcosm of the universe that dominated the natural principle of Yin-Yang and the Five Elements. However, the ideal human body was postulated and the aesthetic consciousness of the body changed into an imaginary view of the human body that proceeded to keep the body fit for and gave birth to the concept of supplementing the deficiency of the beauty of the human body with dress and makeup.

We report the results on the investigation of the association of solar wind dynamics and the occurrence of geosynchronous relativistic electron events. This study analyzed E>2MeV electron fluxes measured by GOES 10 satellite and solar wind parameters by ACE satellite for April, 1999 to December, 2002. Most of the relativistic events during the time period are found to be accompanied by the prolonged period of quiet solar wind dynamics which is characterized as low solar wind pressure, weak interplanetary magnetic field, and fast fluctuations in IMF Bz.

Simulation and signal conditioning on the time domain surface elevation records are conducted to verify the proposed Welch's method in non-directional ocean wave spectrum analysis. These spectrum data are further conditioned to provide wave characteristic that better describe the sea states. Comparison of significant wave height and zero crossing period between the proposed method and a reference toolkit are presented.

Many South Korean universities highly value and place much investment on the development of students' characteristics as their core competency, offering corresponding educational initiatives and programs. The present study specifically evaluated the level of characteristic competency among freshmen at C University, in which characteristic development is at the central to the institution's core competency. The researchers conducted the study to utilize the findings to inform the design of liberal arts courses and extracurricular programs. The study recruited 210 freshmen at C University in Changwon, South Korea. To ensure anonymity of the respondents, an online questionnaire was administered during the data collection period (i.e., between December 5th and 7th, 2022) with a total of 201 faithful responses finally analyzed. The results showed an average characteristic competency level of 4.21 out of 5 among the freshman participants. Notably, the highest score was ranked in the 'righteous domain' (4.27±0.66), whereas the 'behavioral domain' scored the lowest (4.08±0.77). These findings provide valuable insights for the development of educational programs that aim to promote characteristic competency among university students. The implications of the findings are further discussed.

Mismatch between switching frequency and circuit parameters often occurs in industrial applications, which would lead to instability phenomena. The bifurcation behavior of $V^2$ controlled buck converter is investigated as the pulse width modulation period is varied. Nonlinear behavior is analyzed based on the monodromy matrix of the system. We observed that the stable period-1 orbit was first transformed to the period-2 bifurcation, which subsequently changed to chaos. The mechanism of the series of period-2 bifurcations shows that the characteristic eigenvalue of the monodromy matrix passes through the unit circle along the negative real axis. Resonant parametric perturbation technique has been applied to prevent the onset of instability. Meanwhile, the extended stability region of the converter is obtained. Simulation and experimental prototypes are built, and the corresponding results verify the theoretical analysis.

The quality of chaotic mixing in square cavity flow was studied numerically by CFD simulation and particle tracking technique. The chaotic mixing was generated by using time-periodic electro-osmotic flow. Finite Volume Method (FVM) was employed to get the stretching and folding field in cavity domain. With adjusting the initial condition of concentration distribution, the best values of modulation period and Peclet number which gave us good mixing performance was determined precisely. From $Poicar{\acute{e}}section$and Lyapunov exponents for characteristic trajectories we find that mixing performance also depends on modulation period. The higher value of modulation period, the better mixing performance wag achieved in this case. Furthermore, the results for tracking particle trajectories were also compared between using of Bilinear Interpolation and Higher-order scheme. The values of modulation period for obtaining best mixing effect were matched between using FVM and particle tracking techniques.

A bridge resistance deviation-to-period (BRD-to-P) converter is presented for interfacing resistive biosensors. It consists of a linear operational transconductance amplifier (OTA) and a current-controlled oscillator (CCO) formed by a current-tunable Schmitt trigger and an integrator. The free running period of the converter is 1.824 ms when the bridge offset resistance is $1k{\Omega}$. The conversion sensitivity of the converter amounts to $3.814ms/{\Omega}$ over the resistance deviation range of $0-1.2{\Omega}$. The linearity error of the conversion characteristic is less than ${\pm}0.004%$.

This paper presents quasi-zero-stiffness (QZS) characteristic of a passive isolator using flexures under compression force. The passive isolator consists of a positive stiffness element (a vertical coil spring) and a negative stiffness element (flexures under compression force), and their proper combination of the positive and negative stiffness elements can produce both substantial static and zero dynamic stiffness, so called QZS. Firstly, a nonlinear dimensionless expression of a flexure under compression force is derived. A dynamic model of the passive isolator is developed and numerical simulations of its time and frequency response are performed. Then, undesirable nonlinear vibration is quantified using a period doubling bifurcation diagram and a Poincare's map of the isolator under forced excitation. Finally, experiments are performed to validate the QZS characteristic of the passive isolator.

Water supply capacity and operational capability in agricultural reservoirs are expressed differently in the limited storage due to seasonal and local variation of precipitation. Since agricultural water supply and demand basically assumes the uncertainty of hydrological phenomena, it is necessary to improve probabilistic approach for potential risk assessment of water supply capacity in reservoir for enhanced operational storage management. Here, it was introduced the irrigation vulnerability characteristic curves to represent the water supply capacity corresponding to probability distribution of the water demand from the paddy field and water supply in agricultural reservoir. Irrigation vulnerability probability was formulated using reliability analysis method based on water supply and demand probability distribution. The lower duration of irrigation vulnerability probability defined as the time period requiring intensive water management, and it will be considered to assessment tools as a risk mitigated water supply planning in decision making with a limited reservoir storage.
