The purpose of this study is to investigate the effect of voluntary purchasing motives on insurance consumer satisfaction. The purpose of this study is to investigate the direct and indirect effects of insurance consumption satisfaction including psychological needs of consumers that induce voluntary purchase motivation based on psychological self-determinism theory. The research hypotheses and models were verified through structural equation analysis using online surveys of 1,225 insurance consumers. As a result of the study, the satisfaction of insurance consumption is increased when purchasing by voluntary purchase motive, in which consumers perceive the necessity of purchasing themselves. The positive perception of insurance consumption autonomy and insurance consumption environment increases the motivation to purchase voluntarily, Respectively. Through this study, it is suggested that excessive marketing of insurance companies and self-confidence of insurance consumers may hinder insurance consumption satisfaction and education of consumption attitudes of financial consumers to raise awareness of autonomous rights and responsibilities of insurance consumers.

Objective: The purpose of this study was to assess the changes in height and inclination of the articular eminence during the growth period. Methods: One hundred and sixty subjects (71 males and 89 females) with a normal skeletal pattern and TMJ function, ranging in age from 5.9 to 19.7 years were divided according to their chronological age into six groups. Lateral individualized corrected TMJ tomograms were taken of all subjects, and the height and inclination of the articular eminence were measured. UNIANOVA was used to compare the differences between the age groups. Mann-Whitney test was used to compare the differences between male and female subjects. Results: The height and the inclination of the articular eminence were increased and became steeper with age, and the height and the inclination were larger in male than in female subjects. Conclusions: Dynamic changes in the height and the inclination of the articular eminence were observed during the growth period, therefore a full understanding of the growth of the articular eminence is important for orthodontic and orthopedic treatment in this period.

The travel time of flash floods along mountain streams is mainly governed by reach-average velocity, rather than by the point velocity of the locations of interest. Reach-average velocity is influenced by various factors such as stream geometry, streambed materials, and the hydraulic roughness of streams. In this study, the reach-average velocity in mountain streams was measured for storm periods using rhodamine dye tracing. The point cloud data obtained from a LiDAR survey was used to extract the average hydraulic roughness height, such as R_a, R_max, and R_z. The size distribution of the streambed materials (D₅₀, D₈₄) was also considered in the estimation of the roughness height. The field experiments revealed that the reach-average velocities had a significant relationship with flow discharges (v = 0.5499Q^0.6165 ), with an R² value of 0.77. The root mean square error in the roughness height of the R_a-based estimation (0.45) was lower than those of the other estimations (0.47-1.04). Among the parameters for roughness height estimation, the R_a -based roughness height was the most reliable and suitable for developing the reach-average velocity equation for estimating the travel time of flood waves in mountain streams.

Chin is located on most prominent portion of the face, so make more important esthetic value in impression. So historicaly, many authors had made efforts on correction of deformed chin, termed genioplasty. But those technique have been performed on limited cases, which have normal shape or width of chin. In the cases with more narrow or short chin, location of mental foramen or root of incisors restrict the use of such technique. But modified genioplasty technique we used can be performed without any restriction and change of frontal profile of chin. So we report a case that was performed with modified horizontal step osteotomy for advancement genioplasty, which had been reported by Hinds and Kent, with some complications.

The counter weight filling is a technology to accumulate soils on the side of berm with a proper width and height for improving the stability of the embankment. This study aims to assess a feasibility of the counter weight filling in the construction of pavement roads for recovery of shear failure during the construction. An effective counter weight filling section was suggested using the numerical analysis. The results showed that the effective counter weight filling section is two-fold (x2) higher than the ratio of width in counter weight filling : embankment height and one third (1/3) to the ratio of height in counter weight filling : embankment height. Also a range of effective trench crossing the counter weight filling required when a trench crossing counter weight filling is installed was suggested by supplying a proper distance between the counter weight filling section and cross-sectional trench.

The present study examined the reversal cyclic flexural behavior of walls with jacket section approach for seismic strengthening through forming the boundary elements at both ends of the wall. The prestressed wire ropes were used for the lateral reinforcement to confine the boundary element of the wall. The main parameter investigated was the height of the jacket section for strengthening. The limit height of the strengthening jacket section was determined by comparing the moment distributions between the existing and strengthened walls. Test results showed that the examined jacket section approach was significantly effective in enhancing the flexural resistance of walls, indicating 46% higher stiffness at peak strength and 210% greater work damage indicator, compared with the flexural performance of the unstrengthened wall. The ductility of the strengthened walls was insignificantly affected by the height of the jacket section when the height is greater than twice the wall length. The flexural capacity of the strengthened walls was 22% higher than the predictions obtained using the equivalent stress block specified in ACI 318-14.
