Online supporters are the group of people selected by companies for the online promotion of their products or services and focus on generating messages that are conducive to stimulating hands-on experiences with companies' products and services to create advertising effects. This study examined how reviews offered by blogs operated by fashion brands' online supporters influence consumer's brand attitudes and purchase intentions. Specifically, this study examined how brand awareness and directions of review messages influences consumers' brand attitudes and purchase intentions. This study employed a 2 (brand awareness: high awareness vs. low awareness) ${\times}$ 3 (review direction: one-sided positive, two-sided positive & negative, one-sided negative) between-subject factorial design. In total, 180 respondents participated, thus garnering 30 responses for each of the six conditions. The results of two-way ANOVA revealed the significant main effect supporters' review message direction on consumers' brand attitudes and purchase intentions. Two-sided messages were rated high for brand attitude and purchase intention compared to one-sided positive or negative or positive directions. The interactions between brand reputation and message direction were significant for brand attitude, but not for purchase intention.

A multi-megawatt long pulse ion source (LPIS) of neutral beam injector was developed for the KSTAR. Beam extraction experiments of the LPIS were carried out at the neutral beam test stand (NBTS). Design requirements for the ion source were 120 kV/65 A deuterium beam and a 300 s pulse length. A maximum ion density of $9.1310^{11}$ $cm^{-3}$ was measured by using electric probes, and an optimum arc efficiency of 0.46 A/kW was estimated with ion saturation current of the probes, arc power, and total beam area. An arcing problem, caused by the structural defect of decelerating grid supporter, in the third gap was solved by the blocking of backstream ion particles, originated from the plasma in the neutralizer duct, through the unnecessary spaces on the side of grid supporter. A maximum drain power of 1.5 MW (i.e. 70 kV/21 A) with hydrogen was measured for a pulse duration of 0.5 s. Optimum beam perveance was ranged from 0.75 to 0.85. An improved design of accelerator for the effective control of beam particle trajectory should provide higher beam perveance.

The purpose of this study was to examine the role performance and self-confidence of the fathers with children in grade school. Further, this study explored the variables that affect positively the self-confidence of the fathers. A survey questionnaire was used for this study. The participants of this study were 340 fathers with children aged between seven and nine residing in Gyeongsangnam-do. As for the performance of father's roles, the average score was higher in 'conversation with children' and 'expressing affection to children', whereas it was lower in 'raising children' and 'educating children'. As for the self-confidence regarding their father's roles, the score was higher in the cognitive dimension than in the emotional dimension. In general, the fathers tended to evaluate their role performance as fathers positively. The variables that affected the cognitive dimension of self-confidence as a father were conversation with children, supporter role, under-standing children, and educating children. The variables that influenced the emotional dimension, on the other hand, were child-rearing role, husband's role, supporter role, and expressing love to children.

SPS(Spark Plasma Sintering ) is known to be an excellent sintering method for porous materials. In the present work an attempt has been made of fabricating porous 316L Stainless steel with good mechanical properties by using controlled SPS process Porosity was 21%~53% at sintering temperature of $600^{\circ}C$~100$0^{\circ}C$ The limit of porosity with available mechanical strength was 30% at given experimental conditions. Porosity can be controlled by manipulating the intial height of the compact by means of the supporter and punch length. The applied pressure can be exerted entirely upon the supporter, giving no influence on the specimen. The specimen is then able to be sintered pressurelessly. In this case porosity could be controlled from 38 to 45% with good mechanical strength at sintering temperature of 90$0^{\circ}C$. As the holding time increased, neck between the particles grew progressively, but shrinkage of the specimen did not occur, implying that the porosity remained constant during the whole sintering process.

This paper describes the development of a novel walking assistance robot for the elderly and infirm. In the case of simple walking assistance devices, the walking safety and effectiveness are somewhat low; hence, caregivers are frequently required. The walking assistance robot developed in this research is capable of securely and conveniently assisting a walking user by using electric motors and various devices without a caregiver. The main features include the following. First, the walking safety is improved by using a pelvis supporter, and the robot is able to follow the user effectively by means of ergonomic motion sensors and electric powered wheels. Second, it is possible to adjust the load applied to the lower body by adjusting the height of the pelvis supporter. Finally, it is possible to inform the approximate distance and direction of any obstacle around the robot using the sounds and vibrations for the blind and the hearing impaired. The performance of the developed walking assistance robot was successfully verified using a walking assistance test in a narrow-corridor environment.

In this study, elastoplastic finite element analysis with multi-body treatment was used to elucidate the mechanical phenomena occurring from pre-stressing of die-system. A finite element analysis model with detailed conditions is proposed. The effects of die pre-stressing slope on the circumferential components of the pre-stressed die inserts were evaluated. The role of tight fitting between the supporter and die case was also emphasized because it has a significant effect on the undesirable change in the target slope of machined inner surface of the die case around the die insert. The two mechanical problems include the one between die-insert and die case and the other between supporter and die case, and their correlation is minimized to establish the optimum design in the die structural design stage because it cannot be quantitatively controlled owing to various factors affecting the die structural behavior during die pre-stressing.
