This study defined the concepts of change-readiness, affordance system, agility, and performance, which are becoming increasingly important and necessary in service industry. Also, by verifying the relationship among these factors based on theoretical and empirical researches, it proposed strategic implications for service firms to reinforce their competitiveness. The results of the analysis in this study are as follows. First, the factors of technology, organization, and environment had significant effects on affordance system. Second, affordance system had significant effects on both agility and performance. Third, agility had a significant effect on performance. Fourth, job uncertainty moderated the relationship between affordance system and agility, but not between affordance system and performance. The results suggest that affordance system is a highly effective method of improving agility of the frontline employees. To maximize the utility of affordance system, sufficient change-readiness in technological, organizational, and environmental factors are required. Reasons and implications of these observed relationships are discussed.

This research aims to analyze gamer's behavior pattern on 'Blade for Kakao' RPG genre based on smart-phone. Three subjects were recruited using the concurrent protocol method to conduct ten episodes in region 1. As a result, it derived four behavior patterns according to the combination of space type affordance and the arrangement affordance of obstacle(monster). The result of this research revealed the forward attack arranged for the fixed obstacles in the wide space, the indirect attack as avoid-type arranged for scattered obstacles in the same space, the hunting up attack once arranged for the crowded obstacles in the same space, and the pulling attack arranged for obstacles in the narrow space. Moreover, it revealed the character growth and the optimization of attack method according to the attribute affordance of the obstacle(monster). This research expect to offer the design guideline for game level design to investigate the relationship between the game play and affordance in RPG genre based on smart-phone.

It has been known that the tool characteristics embedded in physical tools and virtual tools act with different underlying mechanisms in a user's knowledge acquisition and conceptual understanding. This overview study examines the learning process through the use of physical and virtual tools from the perspective of conceptual frameworks, affordability that tools present, and the depth of cognitive engagement that occurs in the process of learning concepts through various learning activities. Based on the conceptual frameworks, the results of previous comparative studies were reinterpreted. It was found that what mattered for learning is the amount of new information that a tool provides and the different level of cognitive engagement that students use through various learning activities. Finally, the implications to be considered when teachers use physical and virtual tools to help students better understand various concepts are discussed.

TV program favorability does not necessarily lead to actions related to programs such as producing videos, emotions, webtoons, and goods, participating in concerts, and fan meetings. Therefore, there might be a mediating variable between program favorability and related behaviors. This study presents relationships as a mediating variable. This study assumed that if the program favorability is high, a positive relationship can be formed with the program, the characters on the show, the groups appearing in the program, the viewers who watch it together, and viewing affordance. Those formed relations can have positive effects on the program related activities. In the conducted online survey, we found that high favorability has positive effects on intimate relationships with the program, viewing affordance, characters, and other viewers, and these relationships have positive effects on program-related offline and online activities. However, the relationship with the character group has a negative effect on program-related behavior. This may be the result of viewers feeling alienated from highly intimate relationships formed among characters appearing in the show.

Organizational trust (OT) plays a substantial role to attain competitive advantages. It is an effective way to enhance organizational effectiveness. OT makes employees to have a positive emotion toward a firm, also it contributes employees to bring a spontaneous behavior. The purpose of this study is to investigate the relationships among OT, organizational commitment (OC), and organizational citizenship behavior (OCB) theoretically and empirically. A total of 228 cases in 15 Chinese companies are used for empirical analysis. The results show that OT has a positive effect on OC and OCB. It is suggested that OT is an important variable to improve emotional and continuance commitment. Also the results reveal that OCB is a meaningful dependent factor that is affected by OC.

The bodyguard is continuously training basic physical training and security art martial to protect the privacy of security target, prepare and deal with external contingencies and threats. Currently, university students majoring in security are required to take a judo class, one of their security art martial, which can use a technology to catch, crush and repress opponent. Therefore, this study identified the effects of systematic training on body composition, Performance fitness, growth hormones, and IGF-1 among male university students through a 10-week judo training program so that it was committed to providing objective data to enhance the value of judo as a security art martial and as a result, we have a conclusion as follows: After 10 weeks of judo training, muscle mass increased significantly, and body fat rate and BMI decreased significantly. The muscular strength and power of Performance fitness were shown to increase significantly, and growth hormones were shown to increase significantly. In total, the above results showed that for judo training university students, overall body composition improved positively, the muscular strength and power of active physical fitness improved, and growth hormones increased. Thus, the increase in muscle strength and growth hormones through judo training will encourage fat breakdown due to the development of the body's muscles and increase bone density in the spine, thereby reducing the risk of fractures and preventing injury to the trainees who are performing a security art martial. It will also greatly help your health by preventing obesity, cardiovascular and metabolic diseases, which eventually will enhance your bodyguard function and prolong your life as a bodyguard.

During pregnancy, maternal immune activation (MIA) from infection increases the risk of neurodevelopmental diseases, including schizophrenia and autism spectrum disorders. MIA induced by polyinosinic-polycytidylic acid (poly (I:C)) and lipopolysaccharide (LPS) in animal experiments has led to offspring with abnormal behaviors and brain development. In addition, it has recently been reported that microglia, which reside in the brain and function as immune cells, play an important role in behavioral abnormalities and brain development in MIA-induced offspring. However, the underlying mechanism remains unclear. In this study, we investigated whether microglia-specific inhibition of GPR56, a member of the G protein-coupled receptor (GPCR) family, causes behavioral abnormalities in brain development. First, MIA induction did not affect the microglia population, but when examining the expression of microglial GRP56 in MIA-induced fetuses, GPR56 expression was inhibited between embryonic days 14.5 (E14.5) and E18.5 regardless of sex. Furthermore, microglial GPR56-suppressed mice showed abnormal behaviors in the MIA-induced offspring, including sociability deficits, repetitive behavioral patterns, and increased anxiety levels. Although abnormal cortical development such as that in the MIA-induced offspring were not observed in the microglial GPR56-suppressed mice, their brain activity was observed through c-fos staining. These results suggest that microglia-specific GPR56 deficiency may cause abnormal behaviors and could be used as a biomarker for the diagnosis and/or as a therapeutic target of behavioral deficits in MIA offspring.
