While past studies on e-books have mainly focused on the uses and gratifications (UG) and technology acceptance model(TAM), this study rather analysed the innovation resistance factors of adopting the e-book based on the innovation resistance model. The research model comprises of two factors: 1) innovation characteristics which include relative advantages, compatability and complexity, 2) user characteristics which encompass attitudes towards innovation and existing products (i.e., paper books). Using online survey questionnaire, this study examined the effects of those innovation and user characteristics on the innovation resistance, and the relationship between innovation resistance and intention of adoption. The results showed that complexity and attitude towards existing products affected the innovation resistance which has negative influence on the intention of adoption. Accordingly, it is necessary to improve the ease of use in the whole process from purchase to reading experiences, and highlight e-books' own interactive features and functions which are perceived as different from paper-book user experience.

This paper proposes a cost-efficient and flexible FPGA-based logic circuit emulation platform. By improving the performance and adding more features, this new platform is an enhanced version of our LAPG. It consists of an FPGA-based hardware engine and software element to drive the emulation and monitor the results. It also provides an interactive verification environment which uses an efficient communication protocol through a bi-directional serial link between the host and the FPGA board. The experimental results show that this new approach saves $55%{\sim}99%$ of communication overhead compared with other methods. According to the test results, the new LAPG is more area efficient in complex circuits with many I/O ports.

Because chronic pain disorder may has multiple causes or contributing factors, including physical, psychological, and socio-environmental variables, the treatment of patients with the disorder requires biopsychosocial approaches in a multidisciplinary setting. In treating chronic pain, it is important to address functioning as well as pain, and treatment should be to increase functional capacity and manage the pain as opposed to curing it. Therefore treatment goal should be adaptation to pain or minimizing pain with corresponding greater functioning. Treatment begins with the initial assessment, which includes evaluation of psychophysiologic mechanisms, operant mechanisms, and overt psychiatric comorbidity. Psychiatric treatment of the patients requires adherence to sound pharmacologic and behavioral principles. There are four categories of drugs useful to psychiatrist in the management of chronic pain patients : 1) narcotic analgesics, 2) nonsteroidal antiinflammatory drugs, 3) psychotropic medications, and 4) anticonvulsants, but antidepressants are the most valuable drugs in pharmnacotherpy for them. Psychological treatments tend to emphasize behavioral and cognitive-behavioral modalities, which are divided into self-management techniques and operant techniques. Psychodynamic and insight-oriented therapies are indicated to some patients with long-standing interpersonal dysfunction or a history of childhood abuse.

Today, Internet service is a most important Information Source. So, the Power Line Communication has been achieved to offer Internet service to Last-Mile area. But, Power Line is not suitable for communication, So, electromagnetic wave is generated from Power Line during flow of communication information. And the electromagnetic wave is interfered with Wireless Communication Service using the same frequency range. In this paper, the Notch Filter and the Spectrum Sensing technology are proposed to reduction of interference between Power Line Communication and Wireless Communication Service. The Spectrum Sensing technology is the core technology of the Cognitive Radio (CR) system. CR is the technology that temporarily allocates the frequency bandwidth by scanning surrounding wireless environments to keep licensed terminals and search the unused frequency bandwidth. The proposed emulator is implemented with Spectrum Sensing and Notch Filter system using Embedded Board.

The digital divide has become an important social issue in the two waves of informatization and aging society. This study is to comprehensively examine various theoretical approaches and discussions on the mechanisms of the digital divide and to synthetically understand the features of the digital divide in old age. This study examines 1) four theoretical approaches on the mechanisms of digital divide among people in general, 2) three theoretical perspectives and six specific explanations on the digital divide in old age, and 3) five controversial features and concepts of the digital divide in old age. Consequently, this study suggests the need for a comprehensive approach to the multi-dimensional digital divide in old age and more attention to the digital divide in old age in terms of individual well-being and social inequalities. Further implications and limitations are discussed.

This paper is studied on the effect of the bolt joint stiffness on the Thrust Measurement Stand(TMS). TMS is a test stand for thrust performance of the propulsion system, which depends on two factors: The $1^{st}$ is the parallel degree between directions of the thrust vector and action lines of the corresponding measuring load cells for the vector, and the $2^{nd}$ is the orthogonality between action lines of the measuring load cells. Therefore, it is essential to maintain the original shape of the TMS under operating conditions. In this paper, it is examined how the geometric tolerance of the bolt joints and threads of the load cell trains affect the performance of the TMS. Also, some techniques to overcome related problems are proposed.

The purpose of this research is to suggest effective teaching and learning method suitable for IT-gifted primary school students based on their learning style. This study investigated the means of identifying IT-gifted students by comparing IT-gifted's learning style with average student's. Grasha-Reichmann Student Learning Style Inventory was used, which was proved to identify gifted IT students with 66.45% accuracy. As a result, The learning style of IT-gifted was determined as independent, competitive, participant Therefore, self-directed learning methods seem to be suitable for IT-gifted. IT-gifted also need to have more opportunities to participate in learning activities and discussion with their peers.

Nursing problems of 48 hospitalized patients with Conduct Disorder at a Child-Adolescent psychiatry inpatient were analyzed by reviewing nursing records. The results showed that the problems such as ineffective individual coping, impaired social interaction, disturbance in self-concept, potential for violence, alteration in parenting, altered growth and development were continued from early to later phase of the hospitalization and the other problems such as self-care deficit, anxiety, sleep disturbance, altered nutrition, hyperthermia were temporary. The etiologic factors related to these problems were underdeveloped ego, low self-esteem, dysfunctional parent-child relationship, some situational crises in family and handicap like mental retardation or epilepsy. Therefore nursing approach for the patients with Conduct Disorder should focus on ego growth and improvement of interpersonal relationship through systematic and long-term nursing plans and interventions for these patients and their family.

RFID-based games, which use a RFID reader and RFID chips, will expand existing computer games, which use a computer screen, a keyboard or a mouse. This paper presents 4 RFID digital board game contents which are conducted by initial developers; the three of them use the screen and control the games with RFID chips and, one is a different attempted game which can exclude the screen and be immersed to the board. While initial developers use object recognition of RFID, we need to develop game contents and game interface which can recognize positions of the objects. According to the initial developer"s developing process, the cooperative system between the game technical developers and the contents developers should be necessary. Also, the interface should be developed for young children to participate and operate.

A virtual enterprise (VE) can be mapped into a multi-agent system (MAS) that consists of various agents with specific role(s), communicating with each other to accomplish common goal(s). However, a MAS for enacting VE requires more advanced mechanism such as context that can guarantee autonomy and dynamism of VE members considering heterogeneity and complex structure of them. This paper is to suggest a context-based MAS as a platform for constructing and managing virtual enterprises. In the Context-based MAS a VE is a collection of Actor, Interaction (among Actors), Actor Context, and Interaction Context. It can raise the speed and correctness of decision-making and operation of VE enactment using context, i.e., information about the situation (e.g., goal, role, task, time, location, media) of Actors and Interactions, as well as simple data of their properties. The Context-based MAS for VE we proposed('VECoM') may consists of Context Ontology, Context Model, Context Analyzer, and Context Reasoner. The suggested approach and system is validated through an example where a VE tries to find a partner that could join co-development of new technology.
