아이템은 게임성을 높여주는 인터랙티브(Interactive) 요소이며, 플레이어에게 다양한 쾌감을 제공하는 요소로써 인간에게 내재된 원초적인 경제욕구를 충족시켜주고 있다. 본 논문에서는 아이템에 명성치를 주고 그것의 DB화를 통해서 플레이어들의 커뮤니티와 경제 시스템을 활성화하여 게임성을 높임과 동시에 해킹등 게임의 역기능 문제를 해결할 수 있다.

Objective: Cognitive-motor trainings had a positive impact on cognitive function and dual-task trainings led to improvements of global cognitive function. The brain activity of the prefrontal cortex (PFC) is another indicator that can infer cognitive function. This study aims to confirm the usability of the interactive system cognitive-motor training program and the changes in the prefrontal cortex through training. Design: Cross-sectional study Methods: In this study, two cognitive tasks were randomly applied to 20 adults as cognitive-motor training using an interactive system, and the same task was performed using the original method. During all tasks, the brain activity of the prefrontal cortex was measured by the change in oxyhemoglobin (HbO) in real-time using Functional Near-Infrastructure. After performing the tasks, the usability of the developed interactive system was evaluated by a usability questionnaire which consists of five items, and each item consists of a 7-point Likert scale that responds from 1 point to 7 points. Results: The HbO levels were increased during cognitive task performance than at the resting phase. And evaluating the usefulness of the interactive system, a questionnaire result showed that it would be useful for cognitive-motor programs. Conclusions: The cognitive-motor training using the interactive system increased the activity of the prefrontal cortex, and the developed wearable sensor-based interactive system confirmed its usefulness.

Purpose: Based on previous researches on social factors of digital item purchase in digital contents distribution platforms such as SNS, we aim to develop the integrated model that accounts for the dynamic and interactive relationship between social structure indicators and digital item purchase. Research design, data and methodology: A PVAR model was used to capture endogenous and dynamic relationships between digital item purchase and network indicators. Results: We find that there exist considerable endogenous and dynamic relationships between digital item purchase and network structure variables. Not only lagged in-degree and out-degree but also in-closeness and out-closeness centrality have significant and positive impacts on digital item purchase. Lagged clustering has a significant and negative effect on digital item purchase. Lagged purchase has a significant and positive impact just on the present in-closeness and out-closeness centrality; but there is no significant effect of lagged purchase on the other two degree variables and clustering coefficient. We also find that both closeness centralities have much higher carryover effect on digital item purchase and that the elasticity of both closeness centralities on the purchase of digital items is even higher than that of other network structure variables. Conclusions: In-closeness and out-closeness are the most influential factors among social structure variables of this study on digital item purchase.

The purpose of this study is to analyze the phenomenon of 'play' in contemporary fashion creation from an interactive point of view and to analyze cases in the contemporary fashion design creation process. The research method was a combined literature review and a case study. As a result of the research, we have derived the creations of interactive fashion design from the viewpoint can be categorized as 'play as creativity', 'mimesis', and 'deviance'. First, creativity can be seen in DIY products, customized products, and clothing that reflects the consumer's way of wearing. By actively intervening in the products and expressing their creativity in the product, it can be considered as a DIY creation. Second, mimesis in the creation of a fashion design that occurs when consumers imitate the designs of the famous fashion designers. Often similarity and difference are generated, while sometimes objects are newly constructed. Third, deviance means that an item is reborn with a completely different intention from the original shape and function by the intervention of the 'hacker' consumer. For example, the logo and the design of a luxury brand are transformed to satirize its legitimacy. In this paper, we analyzed the cases of fashion design creation as an interactive play and investigated their characteristics and tendencies.

체감형 스포츠 게임은 도심 생활 어린이들의 신체활동을 늘릴 수 있는 방안으로 부상하고 있다. 기존의 체감형 스포츠 게임 연구들은 성인 대상이 대부분이며, 어린이의 특성을 고려한 연구는 부족한 실정이다. 어린이를 위한 체감형 스포츠 게임 요소는 일반적인 체감형 스포츠 게임과 어린이 디자인의 공통 요소를 도출한 것이다. 도출된 요소는 실제 게임 종목에 적용하여 어린이용 게임을 제작한다. 본 논문에서는 도출된 어린이용 체감형 스포츠 게임 요소인 몰입감, 상호작용, 신체활동을 적용한 어린이용 스크린 클라이밍 게임을 제작하였고, 사용자평가를 통해 요소가 적절히 적용되었음을 확인하였다. 어린이를 위한 체감형 스포츠 게임 요소를 활용하여 보다 어린이의 특성을 고려한 게임을 제작할 수 있을 것으로 기대한다.

The purpose of this study was to evaluate the validity and reliability of the Penn Interactive Peer Play Scale (PIPPS) for Korean young children, with a special confirmative factor analysis. The participants were composed of 435 5-to 6-year-old children and their parents, and 42 teachers. The instruments included the 32-item exploratory PIPPS (Choi & Shin, 2008), the Preschool Behavior Questionnaire (PBQ; Park, 1992), and the PIPPS on parental reporting. The PIPPS was confirmed, and supported the following constructs resulting in the investigation of 3 factors, 'play disruption', 'play interaction', and 'play disconnection', along with 30 items similar to the PIPPS (2008). Inter-correlations between the sub-factors of PIPPS with those of criterion measures were validated by ratings from the PBQ and the parent version of the PIPPS. The reliability coefficients of the sub-factors of the PIPPS ranged from .85 to .92. In conclusion, 3 factor structure of the PIPPS was appropriate to represent the interactive peer play of Korean young children.

Over the past several years, numerous CALS technologies have been developed for improving productivity and the quality of products and services in an organization. Among these technologies, Interactive Electronic Technical Manual(IETM) has been recognized as one of the most important CALS technologies. IETM is a technical manual authored by means of an appropriate media in a digital format. This study was an attempt to establish conceptual foundations in the literature for IETM. This study described the concept of IETM and differentiated IETM from a technical manual. Also, the author suggested an effective approach to developing an ITEM and explained the relationship between HyTime/MID and IETM.

The purpose of this study was to investigate the construct validity of the Penn Interactive Peer Play Scale on the parent version. The participants of this study were 231 children in the Seoul and Gyeonggi provincial areas. The instruments included the 32-item exploratory PIPPS (Choi & Shin, 2008), and the Preschool Behavior Questionnaire (PBQ; Park, 1992). The data were analyzed by descriptive statistics, factor analysis, Pearson's r and Cronbach ${\alpha}$. The results were as follows. First, the PIPPPS on the parent version was validated with supporting three factors: Play Disruption, Play Disconnection and Play Interaction with 30 items. The sub-factors of the PIPPS were related with those of the PBQ as criterion measurements. The reliability coefficients of the sub-factors of the PIPPS were ranged from .78 to .82.

The looper control of hot strip finishing mill is one of the most important control item in hot strip rolling mill process. Loopers are placed between finishing mill stands and control the mass flow of the two stands. Another important action of the looper is to control the strip tension which influences on the width of the strip. So it is very important to control both the looper angle and the strip tension simultaneously but the looper angle and the strip tension are strongly interacted by each other. There are many control schemes such as conventional, non-interactive, LQ, LQG/LTR, and ILQ control in the looper control system. In this paper, we present the modeling for the looper of a hot strip finishing mill to control the tension of the strip and suggest the non-interactive(cross) and LQG/LTR control method.
