이 논문에서는 MPEG audio 알고리즘의 필터뱅크를 덧셈을 사용하여 저전력으로 구현할 수 있는 구조를 제안하였다. 제안된 구조는 CSD(Canonic Signed Digit) 형의 계수를 사용하며, 입력신호 샘플을 최대로 공유함으로서 사용되는 덧셈기의 수를 최소화하였다. 제안된 구조는 알고리즘에서 사용된 공통입력 공유, 선형위상 대칭 필터계수를 이용한 공유, 공통입력을 이용한 블록 공유, CSD 형의 계수와 공통패턴 공유를 통하여 사용되는 덧셈의 수를 최소화할 수 있음을 보였다. Verilog-HDL 코딩을 통하여 시뮬레이션을 수행한 결과, 제안된 구조는 기존의 곱셈기 구조의 구현면적과 비교하여 $59.6\%$를 감소시킬 수 있음을 보였다. 또한 제안된 구조의 전력소모도 곱셈기 구조와 비교하여 $59.6\%$를 감소시킬 수 있음을 보였다. 따라서 곱셈기가 내장된 DSP 프로세서를 사용하지 않고도, Arithmetic Unit나 마이크로프로세서를 사용하여 효과적으로 MPEG audio 필터뱅크를 구현할 수 있음을 보였다.

본 연구는 시장지향성이 사업성과에 영향을 미치는데 있어서 시장지향성의 관점에서 사업성과와의 관계를 조명 해보고, 시장지향성과 사업성과간의 관계 연구에서 통합적 매개변수들의 역할을 연구하였다. 기존 선행연구에서 매개변수로 사용한 종업원 만족, 차별화 전략, 벤치마킹, 혁신, 경쟁전략, 시장지향성, 직무만족, 조직몰입, 조직간 정보공유 둥을 통합하여 변수들의 중복을 피하고, 상호 독립성이 유지되는 변수들만을 채택하여 종업원만족, 혁신, 경쟁전략의 선택과 실행 등 3개의 변수를 도출하였으며, 여기에다 국내 선행연구에선 아직 사용하지 않은 조직학습을 신규 매개변수로 추가하여 기업역량변수로 설정하였다. 또한 고객만족, 서비스품질, 서비스충성도(애호도), 서비스이미지, 기업이미지, 등을 통합하여 고객만족, 서비스품질, 충성도 등 3개의 변수로 도출하였으며 신규 매개변수로써 기업과 고객간 정보공유를 채택하여 고객반응으로 명명하였다. 여기에서, 각각 4개씩 도출된 변수들은 각각 하나의 차원으로 통합하였으며, 두 차원의 통합적 매개변수들이 어떠한 인과적 역할을 하는지 보다 깊이 연구하였다. 연구가설은 6개의 가설 중 시장지향성과 사업성과 간 기업역량과 고객반응의 통합적 매개변수들의 간접효과가 지지되어 4개의 가설이 채택되었다. 그러나, 시장지향성과 사업성과 간의 직접효과와 기업역량과 고객반응의 중복매개는 기각되었다. 본 연구에서는 이러한 연구결과를 바탕으로 이론적 실무적 공헌을 제안하였으며, 끝으로 본 연구의 한계점과 향후 연구방향을 제언하였다.

As integrated management of scattered knowledge in the organization contributes to organizational performance, organizations are increasing their investment in knowledge management(KM) policies and technologies. For KM to be operated efficiently, the participation of employees performing knowledge-sharing activities is important. This study suggests how shared goal, value congruence, and task interdependence reduce the negative effects of relation and role conflict on the intention to share knowledge. We surveyed workers in organizations that have more than 50 employees and have KM policies, and 381 samples were used for hypothesis testing. As a result of hypothesis testing, we confirmed that a shared goal affects the intention to share knowledge through each of the factors of value congruence, relation conflict, and role conflict. In addition, we confirmed that value congruence and task interdependence moderated conflicts that negatively affected the intention to share knowledge. We identified the conditions that affect the knowledge-sharing activities of employees in terms of individual, organizational, and work structure. Therefore, the results contribute to the establishment of strategies for achieving the performance of the organization's KM.

변화가 잦은 환경에서, 기업은 다른 조직들과의 유기적인 협력과 의존을 바탕으로 생태계(Ecosystem)를 이루고 있다. 이러한 조직간의 유기적인 형태를 기업생태계(Business ecosystem)라 하고, 기업생태계를 이루는 각 조직들은 기업생태계 전체와 운명을 공유한다. 기업이나 조직은 기업생태계 안의 개체가 되며, 각 개체는 생태계 안에서 고유한 역할을 하고, 생태계를 유지하는데 중요한 역할을 한다. 기업 전략의 범위를 기업 내에 한정하지 않고, 해당 기업이 속해있는 기업생태계의 범위로 확대하여 보고자 하는 이러한 관점에서, IT는 중요한 역할을 한다. 첫 째, 기업생태계는 기업 네트워크의 확장된 개념으로 파악할 수 있는데, 이러한 기업생태계에서 개체간의 상호작용에 IT가 중요한 역할을 한다. 두번째, 기업생태계에서는 외부의 자극이나 개체의 상태가 전체 건강성에 영향을 미치는데, 기업생태계를 다이나믹하고 건강하게 유지시키는데에 IT가 필요하다. 본 연구는 기업의 전략적 운명 공통체로써의 기업생태계에 대한 기존연구를 통해, 기업생태계 관점에서 IT 역할을 파악해야 할 필요성을 제시하고, IT역할 구분 시에 필요한 지침에 대해서 논의하여, 추후 수행될 연구의 기반을 마련하는 것을 목적으로 한다.

We examine how women entrepreneurs in contents business experience work/family role conflict and then reveal what kind of conflict management strategies they adopt in varying external and internal conditions. A critical problem faced by female entrepreneur is the tension that exists between their personal lives and business role. This tension is viewed as a form of inter-role conflict in which the role pressure from work and family competes for women's limited time and energy. First, we probe the content and nature of work- family role conflict on the part of female entrepreneurs. Second, we closely look at the three strategies of work/family role manipulation. Family role reduction strategy, work role reduction strategy, and work/family role sharing strategy are identified. Third, we discuss how the choice of the three strategies is affected by internal family salience and the external resources including spouse, family, and financial resources.

In this paper, we propose an efficient integer inverse transform structure for vp9 decoder. The proposed structure is a hardware structure which is easy to control and requires less hardware resources, and shares algorithms for realizing entire DCT(Discrete Cosine Transform), ADST(Asymmetric Discrete Sine Transform) and WHT(Walsh-Hadamard Transform) in vp9. The integer inverse transform for vp9 google model has a fast structure, named butterfly structure. The integer inverse transform for google C model, unlike universal fast structure, takes a constant rounding shift operator on each stage and includes an asymmetrical sine transform structure. Thus, the proposed structure approximates matrix coefficient values for all transform mode and is used to matrix operation method. With the proposed structure, shared operations for all inverse transform algorithm modes can be possible with reduced number of multipliers compared to the butterfly structure, which in turn manages the hardware resources more efficiently.

We explore the impact of individuals'network position toward knowledge sharing intention. In order to identify network positions, we utilize three centrality measures (degree/closeness/betweenness) of individual network participants. The research findings show that the individual network positions significantly affect knowledge sharing intentions. Since an individual with high degree centrality might be the leader or the hub, one makes considerable effort to maintain the network position by actively participating in intra-team and inter-team knowledge sharing, A participant who can quickly interact with many other participants within a team (high closeness centrality) is more interested in intra-team knowledge sharing than inter-team knowledge sharing. Unlike degree centrality and closeness centrality, the betweenness centrality provides a participant with diverse resources located in multiple sub-groups. Although an individual with high betweenness centrality is not at the center of the networks, one plays a crucial role in disseminating and regulating information. Therefore, the individual is likely to have more positive intention toward inter-team knowledge sharing than intra-team knowledge sharing.

A study of flow characteristics of supersonic fluidic oscillators with shared feedback channel inside was carried out. Unsteady CFD analysis were performed and the numerical results were validated by comparison with the experimental ones observed for the same operation conditions. It was found that the mass flow between individual oscillators through the shared feedback channel directly influenced on the oscillating flow mechanism inside the oscillator, and finally on the synchronization of the jet oscillations. It was also observed that the oscillator with shared feedback channel provided higher pressure loss as well as higher oscillation frequency as compared to the single oscillator of the same geometric shape.

With the advent of uniquitous life, changes of users' demands make a public library accomplish roles and functions of a complex service center providing information, education and culture service. As a multi-function center, a public library provides various services based on physical and digital space in ubiquitous environment. Information commons is a basement of physical space in an u-Library. Especially, with the advent of ubiquitous environment, design and use of physical space will be a critical issue for a public library to perform its role and function as a multiple complicated space. This study derives facilities and components for designing and implementing information commons in a public library as a physical space. To perform the goals, this study focuses on the newest trends and requirements through literature study, case study and survey. As a result, this study proposes components of facility and principles of design to implement information commons as a physical space in a public library.

ADHD is a neuro-developmental disorder that begins in childhood, yet may continue into adulthood. Although 3 to 4 percent of adults are affected by ADHD, but only a small proportion of adults ever receive a formal diagnosis and treatment. The core symptoms of ADHD frequently lead to significant academic difficulties that often result in the students' teacher being the first to suspect the disorder. In order for school teachers to effectively deal with ADHD students in school classrooms, they need to have positive attitude toward ADHD students. This study presents a list of ADHD-related web sites which provide educational contents and support for school teachers, and provides the discussions about the current status and the roles of those web sites.
