This paper introduces a computer program ARAP, explaining how it automatically analyzes and evaluates academic research articles and books. It also shows how ARAP can help trace the trend of a certain theory by reviewing existing publications. As an illustration, ARAP is used to review Korean linguistic publications in order to show how Western semantic theories have influenced semantic studies in Korea.

This paper will improve the quality of medical imaging to restore defective pixels on how to present the information you want to increase the efficiency, Using the filter is damaged pixel approximation of the same value to get value, but it is difficult to obtaion. How to get value for the restoration of the original imaged as a way to fill a sweater pattern of missing and how to restore the delta using the filter, compared to the extsting method of excellence.

Despite the importance of the impact of network structure on the relationships between firms and firm performance, few studies have investigated these effects. This study investigates how network openness influences the relationships between TSI, opportunism, technological uncertainty, and supplier performance. We also try to figure out how network openness functions as a governance mechanism.

The purpose of this study was to review the studies related to the problem of context in science education. Firstly, studies on context and context effects in science education (and also those related in cognitive psychology) were summarized according to the topics concerning science learning, such as deductive reasoning and probabilistic judgement, controlling variables, scientific inquiry skills, memory and consistency of misconceptions, selecting cognitive strategies and problem solving, achievement and momentum effect, and interest, religion and culture. Secondly, the common problems appeared from the analysis of the studies were discussed, such as (1) how to define contexts?, (2) how to classify contexts?, (3) how to characterize the effects of contexts? and (4) how to explain the context effects? Finally, the implications of the analysis of the studies on the problem of context were discussed in terms of recent development of science education, such as misconception studies, STS science education and the application of the history of science to science teaching.

Financial soundness in the household sector matters for financial stability and for the real economy. The level of household debt in Korea raises concern about the financial soundness of the household sector due to its size, growth rate and quality. Against this backdrop, we assess the financial vulnerability of borrowers based on an analysis of credit bureau (CB) data, in which the actual credit activities of most individuals are recorded at a high frequency in Korea. We construct over-indebtedness indicators from the CB data and then assess the predictability of forthcoming defaults. Based on the over-indebtedness indicators, we show how borrowers are distributed in terms of over-indebtedness and how the over-indebted differ from average borrowers in terms of their characteristics. Furthermore, we show how the aggregate credit risk in the household sector would change under macroeconomic distress by analyzing how each borrower's credit quality would be affected by adverse shocks. The findings of this paper may contribute to assessing household debt vulnerability and to enhancing regulatory and supervisory practices for financial stability.

This paper examines the social development process of technological innovation for national emergency management. There are relatively few studies on how technological innovations are developed and deployed within social context. This paper investigates innovation processes within social contexts and the role of innovation actors such as citizens, government, and private sector. The the Real-time Disaster Management System (RDMS) is an innovation for citizens to transmit digital images and video clips on disaster toward professional organizations to respond to disasters. This case shows how an innovation in disaster management was developed by social interactions, how open innovation mechanism was deployed, and how end-users involved in innovation processes for disaster management. Finally this paper suggests implications to accelerate innovations for social welfare and social change.

In the trim line of an automobile assembly process, 52.9% of the subjects complained the shoulder and low back pain simultaneously. The Alexander Technique is an educational method which shows people how they are misusing their bodies and how their daily habits of work can be harmful. It also teaches people how to avoid work habits which create excessive amounts of static work and how to reduce the amount of unnecessary muscular force they are applying to their bodies. The purpose of this paper is to investigate the importance of repetitive strain injury on automobile assembly line process and contribute reducing the repetitive strain injury through Alexander Technique.

High temporal-resolution and accurate measurement of skin impedance locus provides useful data for the identification of the physiological/psychological changes and also the identification of acupuncture point. An impedance spectroscopy method using digitally constructed current waveform consisting of many frequency components (multiples of 1Hz) was reported3. The time resolution of the method depends on the lowest frequency used in the waveform construction, and therefore, the measurement would be faster if the lowest frequency is the higher. However, it was not clear that how many and how low frequencies must be used for the estimation of the skin impedance parameters from which the impedance locus can be drawn. This study shows the relationship between the estimation error of the impedance parameters and the frequency coverage of the spectroscopy. The results of this study are expected to serve as the reference of the frequency selection in the impedance spectroscopy.

To survive in rapidly changing business environment, the enterprises of all over the world are trying to integrate their IT infra structure and are trying to automate their business process. Service Oriented Architecture (SOA) is being accepted as an IT standard to support efficient system integration and flexible business process automation between enterprises or departments. The material control system is required this software architecture between manufacturing company and materials supply vendors. This paper introduces concept of SOA, relevant technology about SOA such as Web Services and Business Process Execution Language (BPEL) and Enterprise Service Bus (ESB) and describes how to automate materials control process by designing the material control system based on SOA. The analysis of requirements is proceeded by Unified Modeling Language (UML) and SOA delivery strategy is selected the top-down strategy. And this paper describes how to derive services and operations and how to arrange services in three service layers and how to design business process.
