The purpose of this study is to compare and analyze bust point information presented in literature and the 8th Korean Anthropometric Survey (Size Korea 2021) as a basis for pattern making for Korean adult women. Therefore, the the bust point position was analyzed through the length from the side neckline to the bust point and the horizontal length from the bust point to the chest. The results are as follows. First, Size Korea's population shows an increase in bust circumference and Side Neck Point to Bust Point with age, with the largest Bust-Point Breadth in the 30s, followed by the 20s, 40s, 60s, and 50s. Second, the Bust-Point Breadth in the female Basic Bodice pattern of Kang Soon-hee, and Oh Sun-hee, which were created from the bust circumference measurements of Size Korea's population, was wider than the measurements, and the difference was verified as a highly significant. Third, in the female Basic Bodice pattern of Kang Soon-hee, and Oh Sun-hee created with the bust circumference dimensions of Size Korea's population, the length of Neck Point to Bust Point was shorter than the measured value, and the difference was highly significant. Fourth, the Bust-Point Breadth and Neck Point to Bust Point in the female Basic Bodice pattern of Kang Soon-hee, and Oh Sun-hee, which were created with the bust circumference of the population of Size Korea by age, were analyzed in different age groups and showed significant differences from the measurements of Size Korea.

We consider the problem of estimating the change-point in mean change model with the one change-point. Lombard (1987) suggested change-point estimation based on score functions. Gombay and Huskova (1998) derived a class of change-point estimators with the score function of rank. Various change-point estimators with the log score functions of ranks are suggested and compared via simulation.

This paper proposes a new simplification algorithm that simplifies reconstructed polygonal mesh from 3D point set considering an original point set. Previous method computes error using mesh information, but it makes to increase error of difference between an original and a simplified model by reason of implementation of simplification. Proposed method simplifies a reconstructed model using an original point data, we acquire a simplified model similar an original. We show several simplified results to demonstrate the usability of our methods.

The aim of this paper is to establish a new fixed point theorem for a set-valued mapping defined on a metric space satisfying a weak contractive type condition and to establish a new common fixed point theorem for a pair of set-valued mappings defined on a metric space satisfying a weak contractive type inequality. And we give periodic point theorems for single-valued mappings defined on a metric space satisfying weak contractive type conditions.

In this paper, we define the concepts of commute proximally, dominate proximally, weakly dominate proximally, proximal generalized ${\varphi}$-contraction and common best proximity point in probabilistic Menger space. We prove some common best proximity point and common fixed point theorems for dominate proximally and weakly dominate proximally mappings in probabilistic Menger space under certain conditions. Finally we show that proximal generalized ${\varphi}$-contractions have best proximity point in probabilistic Menger space. Our results generalize many known results in metric space.

Some interesting electrochemical characteristics of waterpen point-to-plate airgaps for dc and ac powers have been investigated at room atmosphere in a metal chamber. It is found that the ac discharge on the Pt point generated much ozone, while the negative do discharge on the waterpen point generated the highest ozone. And, the ac discharges of the waterpen point and the Pt point produced a little $NO_x$. But the dc discharge of the Pt point and waterpen point did not generated $NO_x$ anyway. As a result, it could be said that the water on the pen point acts something to generate ozone and $NO_x$ in room atmosphere.

In this research an equilibrium point of a Wheeled Inverted Pendulum (WIP) running on an inclined road is derived and validated by some experiments. Generally, The WIP has stable and unstable equilibrium point. Only unstable equilibrium point is interested in the research. To keep the WIP on the unstable equilibrium point, the WIP is consistently controlled. A controller for the WIP needs a reference state for the equilibrium point. The reference state can be obtained by studying an equilibrium point of the WIP. This research is deriving dynamic equations of the WIP running on the inclined road and equilibrium of it based on statics. Several experiments are carried out to show the validation of the equilibrium point.

This paper describes static and dynamic weak point analysis of spindle systems to eliminate high concentrated bending point on spindle and improve total stiffness of spindle systems. The weak point analysis is based on the evaluation of bending curves of spindles. For static weak point analysis the bending curve is derived from static deflection curve and for dynamic weak point analysis it is derived from the mode shape curves in consideration of the transfer function at exciting point. The validity of the weak point search methodology is verified by comparison of the static deflection, the natural frequency and the dynamic compliance between the original and the improved spindle.
