  • Human has been living in the relation with diverse artifacts ranging from simple tools to complex systems. The relation is an interaction between user and product with input and output process to achieve a certain goals. Natural inter-connection is very important to this interaction. The visualized operation and the dear feedback of product play a critical role in making input and output distinct at both sides. So product innovation means removing mental and physical loads between product and user based on understanding and analyzing interaction. This study proposes the interaction grid as a framework to visualize the interaction. The interaction grid is the format to describe the input and output process between user and product. Modeling and analysis of interaction is based on the interaction grid. Finally, this study discusses the idea exploration method for product innovation with interaction grid, and develops prototype of interaction analysis system for supporting idea exploration.

  • The spin-orbit interaction has received great attention in the field of spintronics, because of its property and applicability. For instance, the spin-orbit interaction induces spin precession which is the key element of spin transistor proposed by Datta and Das, since frequency of precession can be controlled by electric field. The spin-orbit interaction is classified according to its origin, Dresselhaus and Rashba spin-orbit interaction. In particular, the Rashba spin-orbit interaction is induced by inversion asymmetry of quantum well structure and the slope of conduction band represents the strength of Rashba spin-orbit interaction. The strength of spin-orbit interaction is experimentally obtained from the Shubnikov de Hass (SdH) oscillation. The SdH oscillation is resistance change of channel for perpendicular magnetic field as a result of Zeeman spin splitting of Landau level, quantization of cyclotron motion by applied magnetic field. The frequency of oscillation is different for spin up and down due to the Rashba spin-orbit interaction. Consequently, the SdH oscillation shows the beat patterns. In many research studies, the spin-orbit interaction was treated as a tool for electrical manipulation of spin. On the other hands, it can be considered that the Rashba field, effective magnetic field induced by Rashba effect, may interact with external magnetic field. In order to investigate this issue, we utilized InAs quantum well layer, sandwiched by InGaAs/InAlAs as cladding layer. Then, the SdH oscillation was observed with tilted magnetic field in y-z plane. The y-component (longitudinal term) of applied magnetic field will interact with the Rashba field and the z-component (perpendicular term) will induce the Zeeman effect. As a result, the strength of spin-orbit interaction was increased (decreased), when applied magnetic field is parallel (anti-parallel) to the Rashba field. We found a possibility to control the spin precession with magnetic field.

  • This study was to research and study whether the types of interaction design perform the effective functions and roles as the exhibition space that audiences want centered in the digital media exhibition space. It was to suggest effective space characteristics through analyzing how the interaction design was expressed at the exhibition space and its application. For the analysis, it completes theoretical inquiry on the classification of the space characteristics according to the concept type of interaction and design characteristics. Based on it, it directly visited the exhibition space that reflected the interaction design centered in Seoul City, experienced the given experience, and designed the analyzing frame by composing a checklist after the observation research. Through the designed analysis, it performed a site questionnaire to audiences. It induced the conclusion as follows after analyzing the case space that reflected the interaction design type. First, the program analysis of the space that has the variability is necessary through a variety of digital analysis as there is a limitation that the characteristic of digital media has. Second, in the concept type of the interaction design, it needs the interaction stage among people that can communicate with audiences and stimulate their senses through vidual factors. Third, in the characteristic of the interaction design, it should try to use effective contents to get over the limitation of the space through the interaction in the designated space in case of exhibition. In the following research, it needs to study on the variety of stage plans in detail by supplying contents to audiences and grafting to the exhibition space continuously through using the interaction design that uses digital media at there.

  • The purpose of this study was to analyze the within-group verbal interaction according to leader's personality in Thinking Science activities. For this study, 2 homogeneous small groups by cognitive level selected from one class of sixth grader. Each group was comprised of four students. Leaders of two groups selected from the results of NEO personality assessment and teacher's observation. One who got high scores in extraversion and agreeableness is named a sociable leader, the other who got low scores in extraversion and agreeableness is named a taciturn leader. Verbal interactions during small group activities were audio/video taped and students' interactions were classified into on-task and off-task. On-task included cognitive aspect and affective aspect. Interactions of cognitive aspect were divided into low and high level, also interactions of affective aspect were divided into positive and negative interaction. The results of this study showed that the verbal interactions in the sociable leader group were more activated than those in the taciturn leader group. Also, interaction level of the sociable leader group in cognitive aspect was higher than those of the taciturn leader group. In affective aspect, interaction pattern of the sociable leader group was similar to those of the taciturn leader group. The characteristics of leader's interaction are as follow. The rates of cognitive aspect in the sociable and the taciturn leaders' interactions were much higher than those of affective aspect. This tendency was especially remarkable in the taciturn leader's interactions. However, interaction level of the sociable leader in cognitive aspect was higher than those of the taciturn leader. In affective aspect, positive interaction rate of the sociable leader and the taciturn leader were higher than negative interaction rate.

  • Purpose: This study was conducted to develop a mother-fetus interaction promotion program aimed at enhancing the sensitivity of primiparas, and to evaluate the effects of a mother-infant play interaction. Method: Participants were recruited from OB-GY clinic with postpartum take-care center (17 mother-infant dyads for intervention group and 17 dyads for control group). Data were collected from January 18 to August 5, 2005. For the intervention group, programmed education which focused on mother-fetus interaction in the 3rd trimester was given. For the two groups, home visiting or a postpartum care center was used for data collection of the mother-infant interaction which was conducted at postpartum 1 week and 1 month. Also mother-infant interactions during feeding were videotaped and two trained observers analyzed the tapes. Results: A significant difference was found in mother-infant interaction between the two groups (postpartum 1 week, t=6.10, P=0.000, 1 month t=6.69, p=.000). For variations in mother-infant interaction in the control group, a significant difference was found in between postpartum 1 week and 1 month (t=-2.564, p=.021). In subscale analysis, interactional behavior of the infant significantly increased in both groups. Conclusion: This study showed that the mother-fetus interaction promotion program aimed at promoting mother-infant interaction increase maternal sensitivity. Therefore, this study suggests that this nursing intervention to increase maternal sensitivity to the fetus should be broadly applied with primiparas, as it can be beneficial for formation of the mother-infant relationship, and for promotion of the social, emotional, and cognitive developments of the children.

  • The aim of this study is to demonstrate interaction as a describable field and tries to understand interaction from the perspective of attributes, thus building a theoretical to help interactive designer understand this field by common rule, rather than waste huge time and labor cost on iteration. Since the concept of interaction language has been brought out in 2000, there are varies of related academical studies, but all with defect such as proposed theoretical models are built on a non-uniform scale, or the analyzing perspective are mainly based on researcher's personal experience and being too unobjective. The value of this study is the clustered resource of research which mainly based on academical review. It collected 21 papers researched on interaction paradigm or interaction attributes published since 2000, extracting 19 interaction attribute models which contains 174 interaction attributes. Furthermore, these 174 attributes were re-clustered based on a more unified standard scale, and the two theoretical models summarized from it are respectively focuses on interaction control and interaction experience, both of which covered 6 independent attributes. The propose of this theoretical models and the analyzation of the cluster static will contribute on further revealing of the importance of interaction attribute, or the attention interaction attribute has been paid on. Also, in this regard, the interactive designer could reasonably allocate their energy during design process, and the future potential on various direction of interaction design could be discussed.
