This paper is very exploratory and addresses the issue 'Is a general quality model of software possible?'. If possible, how specific can/should it be?' ISO 25000 Series SQuaRE is generally regarded as a general quality model which can be applied to most kinds of software. Usability is one of the 8 characteristics of SQuaRE's Product Quality Model. It is the main issue associated with SQuaRE's Quality in Use Model too. it is the most important concept associated software quality since using is the only ultimate goal of software products. Playability, however, is generally regarded as a special type of usability, which can be applied to game software. This common idea contradicts with the idea that SQuaRE is valid for most kinds, at least many kinds, of software. The empirical evidences of this paper show that SQuaRE is too specific to be a general quality model of software.

Among emerging devices propelling the growth of mobile devices, smartphones and tablet-PCs are among the most recognizable. In this study, a research model is designed for exploring acceptance-diffusion strategies for tablet-PCs from the viewpoint of consumer perception, which is verified through a survey. The results of this study show that tablet-PCs have great potential to be versatile, multifunctional devices, even though they are currently considered mostly as entertainment-oriented rather than fulfilling the essential needs of everyday life. An analysis of the acceptance model for tablet-PCs revealed that playability, cost level, functionality, and complexity significantly affect user acceptance. An analysis of the diffusion model, on the other hand, showed that playability and user interface have a significant influence on satisfaction, trust, and positive behavioral intention. We also found that cost level is not a major hindrance in the market diffusion of tablet-PCs. The results of this study can be used to establish effective acceptance and diffusion strategies for tablet-PCs and other emerging devices.

Usability is one of the most important concepts regarding software quality. It can be interpreted as the goodness associated with using the software product. This paper distinguishes the goodness of an individual using experience and the goodness of a product for using. This paper proposes a software quality view model which classifies software quality views into two broad categories of end view and means view. End view includes long-term view and short-term view which is classified further into performer's view on software activity and third party's view on software activity. Means view includes intrinsic view and contingency view. The analysis of ISO 25000 Series SQuaRE demonstrates the necessity to decompose product quality model and quality in use model into five models corresponding to the software quality views respectively. The analysis on playability shows that the universal definition of usability may be an illusion. The results provide the theoretical basis to build a comprehensive and consistent body of knowledge regarding software quality, which is consisted with the set of quality models and the theories explaining the relationships among the elements of the models.

Objective: The purpose of this study is to examine the mediating effect of teacher-child emotional, verbal, and behavioral interactions on the relationship between teacher playfulness and children's peer abilities. Methods: The research method used the questionnaire method to collect data on 420 children aged 3-5 years old, targeting 108 homeroom teachers working at early childhood education institutions located in Seoul and Gyeonggi area. The collected data was analyzed using the IBM SPSS 23.0 statistical program and the PROCESS macro of Hayes (2013). Results: This study confirmed that teachers' verbal, emotional, and physical interactions are closely related to young children's peer competence. In addition, it was confirmed that the teacher's playability is an important variable that affects not only the emotional, verbal, and physical interactions between the teacher and the infant, but also the peer competence of young children. Conclusion/Implications: The results of this study have significance as basic data that suggests that it is necessary to improve the playability of teachers and increase the quality level of the multifaceted aspects of teacher-infant interaction in order to support young children's peer competence.

In recent years, the rapid development of VR technology has secured its significant position in the gaming industry. This paper selects the PC and VR versions of Resident Evil 4 as the research objects, aiming to compare the similarities and differences between these two platforms. Through this comparative study, it is evident that the PC version of the game offers most players an excellent gaming control experience through precise and flexible operations. On the other hand, the VR version not only achieves immersive gameplay through virtual reality technology but also delivers more impressive visual effects to players. However, in comparison to the traditional PC version, the VR version incurs higher development costs, necessitating the production team to invest more resources to optimize the gaming experience and strike a better balance between immersion and playability. In conclusion, this study provides a valuable reference for game developers, assisting them in meeting the diverse needs of player groups and enhancing game playability and user satisfaction.

This paper suggests a different reading of James Joyce's "Araby" by offering the video game as a lens through which we can reimagine the story. Understanding the unnamed boy's journey to the Araby bazaar as a fetch quest, this paper focuses on the boy's failure to complete this quest. As soon as the boy promises Mangan's sister something from Araby, his fetch quest begins. In order to complete the quest, the boy must successfully perform three sub-quests: get money from his uncle as early as he can, get on the train for the Araby bazaar on time, and pass through the sixpenny entrance at the bazaar. However, because his uncle comes home late, the boy fails to get the money early, and that sets off the subsequent failures. The boy then takes the train late and arrives at the bazaar so late that he feels he must go through any entrance. So he walks through the adult entrance by mistake. As a result, he does not have enough money to buy a gift, failing the larger quest. But, regardless of this failure, the boy can try these quests as many as he wants until he finally succeeds in completing them. But no matter how the boy tries to accomplish these subquests, he is doomed to fail them because he cannot make his uncle come home early. The more he tries his quest, the more bitterly he realizes that he will ultimately fail. In this respect, the boy's "anguish and anger" should be understood as his epiphany: the re-playability of the game is possible, but all the replays lead to the same failure: losing the game. In this regard, reading Joyce's "Araby" is much like playing a video game.

There has been lower the tilt margin by the increase of coma aberration due to the reduction of wave-length and the increase of numerical aperture for high density recording. The RF signal degradation is increased as the decrease of tilt margin. To compensate the tilt margin, the optical pick-up actuator for high-speed CD/DVD re-writable system should be able to drive the radial-tilt motion. We announce that the 3-axis drive actuator for high-speed CD/DVD rewritable system. And what was more, the DC/AC sensitivities of this actuator are suitable fur the low-speed playability, the high-speed readability and the high-speed rewritability.
