This study analyzes the attitudes of users who use the automatic-play function of mobile-games. It also observes changes in different emotions to enjoyment. For the analysis, the Q methodology appropriate for the subjectivity study was used, and it classified two types of attitudes based on the analysis. After the classification, it defined the characteristic of each type based on Lazzaro's theory on classification of fun. Types with high rate of convenience feature dependency utilize automatic-play feature to play games for collecting and growth, and they prefer managing the game outdoors. Another type enjoyed the experience of problem solving through games. They want the process to be a good skill to possess in game-play. There was also a tendency to perceive oneself as the game's character. Both types were responded positively to using automatic-play to play mobile-games. This is expected to be used as important data for game production, leading to usability evaluation for analyzing the emotional sensitivity of mobile game users.

New game systems have emerged with the rapid growth of Korea smartphone game industry. Especially auto battle system introduced in RPG which is the most popular genre, which has brought a significant change in the understanding of the computer games. To understand this change, it is necessary to look at what circumstances did emerge auto battle system. What is important here is the smart phone as the technical apparatus which defines the presence of a smart phone game, and the use pattern of the smart phone. the technical device and Its use pattern are affecting the activity of the user how to play the game, game developers are to create the game system according to this play style. By examining the appearance and growth of this auto battle system, we can confirm that the micro changes in the game system, reflect changes in the present form of a computer game. This fact will widen the understanding of the history of computer games.

The purpose of this study is to analyze how auto-combat function in mobile RPG satisfies player's desires. The auto-combat is classified into two types-complete and partial- by timing of activation and degree of control. With elicited aspects of play, players' desires are examined based on Lacan's Desire Theory. A player employing partial auto-combat desires to master higher stages with perfect or flawless control, and one's 'object petit a' is to be the difficulty of the stages. On the other hand, a player applying the complete auto-combat demands to fully comprehend the rules of the game and to attain the rewards of completed stage to build more competent characters. Once a player acquires the desirable object, one recognizes the illusion of one's achievement and seeks for new objects. In this succession, auto-combat function is utilized as an active action of willingness for fulfilling one's desire.

Purpose: This study aims to examine such relationships as the experiential value that customers respond to with regard to maintenance service by empirically revealing how the quality of auto maintenance and repair service affects both customer satisfaction and intention to reuse the same service through the Perceived-experiential Value of customers. Research design, data and methodology: The research model was designed with service qualities such as human quality, material quality, interaction quality, and system quality as independent variables, perceived-experiential value as a parameter, and service satisfaction and return visit intention as dependent variables. Through a questionnaire composed of 24 items, a total of 319 survey data from customers with the experience of using car maintenance service centers in Korea were collected and analyzed using a structural equation. Results: The material quality did not affect the customers' perceived-experiential value, whereas the interaction quality had the greatest influence. It is confirmed that human quality, interaction quality, and system quality can generate customer satisfaction and repurchase intention through the perceived-experiential value. Conclusions: The experiential value of customers can play an important medium role in improving satisfaction, with customers considering interaction quality important. Therefore, the auto maintenance and repair service should consider relationship-focused service strategies.

Middleware enables different networking devices and protocols to inter-operate in ubiquitous home network environments. The UPnP(Universal Plug and Play) middleware, which runs on a PC and is based on the IPv4 protocol, has attracted much interest in the field of home network research since it has versatility The UPnP, however, cannot be easily accessed via the public Internet since the UPnP devices that provide services and the Control Points that control the devices are configured with non-routable local private or Auto IP networks. The critical question is how to access UPnP network via the public Internet. The purpose of this paper is to deal with the non-routability problem in local private and Auto IP networks by improving the conventional Control Point used in UPnP middleware-based home networks. For this purpose, this paper proposes an improved Control Point for accessing and controlling the home network from remote sites via the public Internet, by adding a web server to the conventional Control Point. The improved Control Point is implemented in an embedded GNU/Linux system running on an ARM9 platform. Also this paper implements the security of the home network system based on the UPnP (Universal Plug and Play), adding VPN (Virtual Private Network) router that uses the IPsec to the home network system which is consisted of the ARM9 and the Embedded Linux.

The roller bearings play an important role not only sustain radial or axial load of system, but carry out a rotatory movement as a various operating conditions. They happen that incipient faults which were caused by excessive load, manufacturing or assembling process's errors and many other reasons are created. The bearing faults make noise and vibration by a continuous collision of rotatory components, which can lower the quality and stability of auto-transmission. Therefore, it is important to detect the early fault as soon as possible. This paper presents a detecting method for the improvement in quality by developing the program which can be used to analyze and predict the vibrational characteristics caused by roller bearing faults. We completed development of the inspection system of vibration by appling the most efficient detecting methods and verified the system's reliability through experiments.

CD4⁺ regulatory T cells (Tregs) are essential for normal immune surveillance, and their dysfunction can lead to the development of autoimmune diseases, such as type-1 diabetes (T1D). T1D is a T cell-mediated autoimmune disease characterized by islet b cell destruction, hypoinsulinemia, and severely altered glucose homeostasis. Tregs play a critical role in the development of T1D and participate in peripheral tolerance. Pluripotent stem cells (PSCs) can be utilized to obtain a renewable source of healthy Tregs to treat T1D as they have the ability to produce almost all cell types in the body, including Tregs. However, the right conditions for the development of antigen (Ag)-specific Tregs from PSCs (i.e., PSC-Tregs) remain undefined, especially molecular mechanisms that direct differentiation of such Tregs. Auto Ag-specific PSC-Tregs can be programmed to be tissue-associated and infiltrate to local inflamed tissue (e.g., islets) to suppress autoimmune responses after adoptive transfer, thereby avoiding potential overall immunosuppression from non-specific Tregs. Developing auto Ag-specific PSC-Tregs can reduce overall immunosuppression after adoptive transfer by accumulating inflamed islets, which drives forward the use of therapeutic PSC-Tregs for cell-based therapies in T1D.

최근의 차량 인포테인먼트 시스템은 모바일 네트워크 및 스마트폰과 연결하여 다양한 서비스를 제공한다. 과거에는 제조사에서 독자적으로 개발한 OEM 인포테인먼트 시스템이 주를 이뤘지만, Android Auto, Apple CarPlay, Amazon Echo Auto 등의 개방형 플랫폼 생태계가 구축됨에 따라 다양한 차량들이 AI 음성인식 기반 차량 인포테인먼트 시스템을 탑재하고 있다. 이러한 차량 내 인포테인먼트 시스템은 스마트폰과 연동되며, 사용자에 대한 방대한 정보를 저장하고 처리함으로써 사용자의 선호도에 따른 On-Demand 서비스 등 다양한 편리성을 제공한다. 하지만 사용자에 대한 다양한 정보를 차량에 연동하여 사용하는 만큼 개인정보 문제로 이어질 수 있다. 그렇기 때문에 차량 인포테인먼트 시스템은 스마트폰과 같이 포렌식 관점에서 많은 증거를 획득할 수 있는 매체가 된다. 더욱이 스마트폰과 연동되는 시스템이기에 기존 모바일 포렌식 기법을 적용할 수 있다. 따라서 본 논문에서는 차량 인포테인먼트 시스템을 대상으로 수행된 포렌식 연구 분석을 통해 기존 연구에서의 포렌식 기법과 보완점을 도출하고자 한다.
