This study aims at integrating the sociological study of technology and the economic study of technological learning. It is argued that the sociological approaches of innovation have some strong points in criticizing technological determinism, but have some weak points in explaining how the knowledge base for innovation is accumulated. On the contrary, the economic approaches of innovation have strong points in explaining technology accumulation, but ignore socio-political process of innovation. This study suggests the model which integrates the socio-political process and technological loaming process.

This study was conducted to identify sensory processing factors that affect motor and process skills of children with cerebral palsy. A total of 36 children with cerebral palsy who attended at the J pediatric development center and the N rehabilitation hospital in Seoul participated. Pearson's correlation coefficients were used to test the relationship between motor skills, process skills and sensory processing abilities of children. Moreover, hierarchical multiple regression was used to identify the sensory processing factors influencing motor and process skills. Motor skills of children with cerebral palsy were correlated with auditory filtering, low energy/weakness, and visual/auditory sensitivity of sensory processing items, whereas process skills were correlated with tactile sensitivity and taste/smell sensitivity. The hierarchical regression model for motor skills revealed movement sensitivity, auditory filtering, and low energy/weakness as significant factors influencing sensory processing items. However, no factors were shown to influence process skills. The results of this study will be useful as a basic resource for rehabilitation of children with cerebral palsy. However, further studies evaluating a larger population should be conducted to verify the results presented herein.

$C_p$ and other process capability indices are used extensively in industry, However, They are inadequate and widely misused. In a practical application, process average ${\mu}$ is almost always drifted by various assignable causes in process. And control charts will not detect these shifts in process average. In this study, incorporating these undetected shifts, a new capability analysis method is introduced.

In this paper, I have proposed a design of process support system based on CMMI process which can support integrated management and repository for CMMI model processes. The system assists small organization to improve business process and offers institutionalized automatic environment to users for use of CMMI processes. The proposed system also can enhance quality and productivity of project by including features such as convenience of project management, planned project administration and steady process improvement.

The purpose of the research is to propose an integrated project planning process and its implementation method. Although there is increasing interest in the application of the Earned Value Management(EVM) method in the project management area, the progress and maturity of the technical performance have not been included in assessing the Earned Value. The main concept of the planning process is to use cost, schedule, as well as the technical performance in the assessment of the Earned Value Management for Military R&D project management practices. The resulting process can enhance the efficiency of the project work by eliminating the currently duplicated activities between traditional project planning process and the newly implemented Earned Value Management process and by shortening the early planning process duration of projects adopting EVM practices.

The metal finishing industry generates a variety of pollutants such as acidic or alkaline wastewater, chromic compounds, cyanide, heavy metals, and toxic materials. Especially, zinc plating process is one of the processes which cause serious environmental problems. In this study, we applied the proven optimum technology to important unit processes in terms of implement effects through the process diagnosis and analysis. This study aimed to improve the working environment and the environmental pollutions in zinc plating process.

Due to the plasma applied from the outside, which acts as an etchant during the etching process, considerable heat is transferred to the wafer and a separate cooling process is performed to effectively remove the heat after the process. In this case, a direct cooling method using a refrigerant is suitable for cooling through effective heat exchange. The direct cooling method using the refrigerant using the latent heat exchange is superior to the cooling method using the sensible heat exchange. Therefore, in this paper, AMESim is used to design a direct refrigerant cooling system using latent heat exchange simulator was built.The constructed simulator is reliable compared with the actual experimental results. It is expected that this simulator will help to design and search for optimal process conditions.

While applying the systems engineering (SE) in systems development, a series of technical reviews play a critical role and is intended to monitor the status of the progress and outcomes of the project for which appropriate technical plans prepared earlier should be executed. It is noted however that during the technical review executed as planned, a lot of problems usually come out. Included are the ambiguity in the reports of the progress status and outcomes, discrepancies among the opinions from different participants, and the delay in carrying out the tasks. To solve those problems in an early stage, informal reviews are usually adopted before the formal technical reviews are held. A type of the informal reviews is the peer review. This paper is concerned with the peer review process model to make the later technical reviews more effective. Specifically, we first review the necessity and meaning of the peer reviews. We then study a model for the peer review process. To model the process, the methods of an IDEF modeling and schema definition have been applied using a computer-aided SE tool, Cradle(R), in the environment of the national research and development project. As a result, the implemented process model can show hew the peer review process is designed and managed to be utilized in the technical review. The documents related with the peer review process can also be generated automatically from the developed model Database. Finally, a general misunderstanding about the peer review and its improvement plan have also been mentioned.
