The main objective of this article lies in discussing dependecy issues as related to information development in NICs. The theoretical foundation was drawn from theories of 'dependency' and of 'information societies,' The main assertion of the dependency school (the more dependency, the less development) was applied for a test of the relationship between dependency on foreign scientific and technical information (STI) resources and indigenous STI development in NICs. Utilizing a case study method, this study explored the causes and results of dependency on foreign STI in a leading NIC­the Republic of Korea (ROK). First identified were the economic factors that might have influenced the ROK's dependency on foreign STI. Also investigated were the social factors that might have had associations with the R&D personnel's dependency on foreign STI. Regarding the development of information area, this study discussed general features in the process of producing, organizng, and gatekeeping indigenous STIIdentified regarding the ROK's information dependency was the R&D personnel's pattern of using foreign STI resources as well as the country's dependency on foreign STI resources. This study also discussed the socio-economic progress toward an information society in ROK for the past decades. Finally, specific linkages between the selected five variables were examined on the basis of the proposed four hypotheses.

This study focuses on exploring the behaviours of high-tech start-up firms in response to the policy interventions undertaken to promote regional innovation in South Korea since 1997. High-tech start-ups and their technological entrepreneurship are increasingly considered by policy makers and academics to play a crucial role in the generation of innovation and economic development. However, this study started from a basic concern of why government intervention does not necessarily result in an increase of regional innovation capacity. To explain this concern, we constructed a new conceptual framework of 'government dependency' and apply this to 'Daedeok,' a regional innovation system in South Korea, to explore the reproduction of path dependency as an impact induced by innovation policy. This conceptual framework was developed by remodeling path dependency approaches through a systemic and interactive lens. An empirical study used qualitative interviews of start-up founders to delineate the emergence of a new development path and the extent to which dependency was reproduced in the Daedeok regional innovation system. Empirical analysis suggested that 'reliance' and 'persistence' were the crucial factors in the production and reproduction of the government dependency. Some firms accepted dependency as reliance, but others regarded it as policy utilization. Thus, a critical juncture could not be clearly identified in actors' behaviour. It was also unclear if dependency had hindered innovation, but it was shown that the regional and institutional contexts strongly influenced the reproduction process. The study concludes that the construct of government dependency can also provide useful insights into policy learning as well as the success of government interventions.

The contents of this paper can be divided into three parts. First assert is that the attributes of technology determine the characters of the technology transfer and such technology transfer is an unequal exchange. Second, the progresses of the states of development countries and under-development countries made the technology transfer into the technology dependency, that is, from the dependency of consumption to the dependency of Production. Final1y, we analyzed the problems of technology self-reliance and presented the Polices overcoming the technology dependency.

The purpose of this study lies in identifying Korean scientists' dependency on foreign scientific and technical information (STI), with emphasis on investigating the causes and results. Especially, this study intends to investigate the impacts that a growing dependency on foreign STI might have brought and will bring about on the development of indigenous STI in ROK. To the end, the present discussion covers the following specific research questions: 1) what are the major information sources used by Korean scientists to locate STI necessary for research-related activities\ulcorner 2) to what extent do Korean scientists use foreign STI for research-related activates, as compared to the use of domestic STI\ulcorner 3) what are the major factors causing the information dependency among Korean scientists and what are the results of the growing information dependency\ulcorner And finally, 4) what suggestions can be made for ROK to further its indigenous STI development, while minimizing its dependency on foreign STI\ulcorner Survey method, together with citation analysis method, is employed as the major data collection technique. The survey sample consists of 167 most 'representative' Korean scientists selected on the basis of their research productivity. 167 specially-designed questionnaires were mailed and 104 out of 167 were responded. Follow-up interviews were carried out for 32 out of 104 respondents, who returned the questionnaire but did not answer some specific questions. The data collected from these 104 respondents were analyzed on the basis of two distinguished groups namely, junior and senior scientist groups. Among the 104 respondents, 58 a n.0, ppeared to belong to a group of senior scientists (older than age 45 and finished their final degrees since 1980), and 46 belonged to a group of junior scientists (younger than age 45 and finished their final degrees before 1980). The major findings of the present study include: 1) Korean scientists regard 'scientific and technical journals and books'as the most important information source to obtain the recent STI; 2) their dependency on foreign STI, for the purposes of research and teaching, is extremely high (information dependency for research activities is 88.5%, and that for teaching activities 91.2%); 3) the information dependency of junior scientists are higher than that of senior scientists; 4) Korean scientists' growing information dependency is closely related to both small quantity and low quality of domestically-produced STI, and has a statistically significant relationship with their educational background; and finally, 5) in order to theoretically explain the growing information dependency of Korean scientists, a hypothesis - 'chronic cycle of information dependency' was developed and introduced. The present study suggests the promotion of indigenous STI as a desirable alternative to escape from the 'chronic cycle of information dependency. Localization of the imported foreign STI is suggested as a good strategy for the indigenous STI development, and also suggested are STI policies for both success of localization process and promotion of more efficient STI flows at national and international level.

The aim of this study was to identify the differences in cellular phone dependency and its use levels of usage purposes according to children's gender, and also to analyze the differences in individual and interpersonal relations development due to cellular phone dependency in children based on gender. Using the first year data of the Korean Child and Youth Panel Survey(KCYPS) 2010, this study analyzed 1,604 fourth graders who have their own cellular phones. For statistical analysis, descriptive statistics were calculated and mean difference analyses were conducted. The results showed that there was no difference between boys and girls in cellular phone dependency. The girls' total phone use level was higher than that of boys and meaningful gender differences in the phone use levels were found in the five phone usage purposes. In both boys and girls, the higher phone dependency groups demonstrated higher levels of phone use in more than eight usage purposes, lower self-resilience and self-regulating learning ability, and less positive peer and teacher relations. These findings show the importance of being concerned about and educating children in the fourth grade about the proper uses of cellular phones.

This paper explores a structuring method for solid modeling processes of an automobile automatic transmission-lever design. The aim of this work is to establish standard procedures to minimize iterations and trial and errors during the product development process to increase development time and costs. The design of the transmission-lever is periodically required to be changed with the model change of an automobile. The transmission-lever design process has mainly depended on the designer's experience. It causes to make difficulties to handle the dependency of components. The design process can be improved by resolving the dependency problem using the DSM. The process of applying the DSM provides a systematic way for the solid modeling of transmission-lever by the consideration of geometry dependency.

The purpose of this study was to examine the longitudinal relationships between Korean adolescents'mobile phone dependency, trajectories of depression, and self-regulated learning abilities. To achieve these goals, structural equation modeling analysis was conducted, using the 3rd, 5th and 7th wave of the data on 4th graders taken from the Korean Children and Youth Panel Survey. The results can be summarized as follows. First, growth-curve longitudinal analysis indicates that depression in 6th through 10th grade has increased. Second, mobile phone dependency among adolescents at 6th grade has a significant effect on both the initial value and the rate of change in depression. Also, the initial value and the rate of change in depression have significant relationships with mobile phone dependency at 10th grade. Moreover, both increased levels of mobile phone dependency and the rate of change in depression significantly influence adolescents'self-regulated learning abilities at 10th grade. Based on a longitudinal data set, these findings demonstrate the causal relationships between Korean adolescents'trajectories of depression and their mobile phone dependency. The findings also provide a comprehensive framework with implications for adolescents'development through an understanding of the relationships between adolescents'depression and mobile phone dependency, which impact their self-regulated learning abilities.

The system optimization is a technique that changes the structure of the program in order to extract the duplicated modules without changing the source code, reuse of the extracted module. Structure-oriented development and object-oriented development are efficient at crosscutting concern modular, however can't be modular of crosscutting concept. To apply the crosscutting concept in an existing system, there is a need to a extracting technique for distributed system optimization module within the system. This paper proposes a method for extracting the redundant modules in the completed system. The proposed method extracts elements that overlap over a source code analysis to analyze the data dependency and control dependency. The extracted redundant element is used to program dependency analysis for the system optimization. Duplicated dependency analysis result is converted into a control flow graph, it is possible to produce a minimum crosscutting module. The element extracted by dependency analysis proposes a system optimization method which minimizes the duplicated code within system by setting the crosscutting concern module.

There have been numerous researches in minimizing the total cost of program development in order to improve productivity of the programs. The incremental evaluation is the evaluation method of reevaluating only affected parts instead of reevaluating overall program when the program has been changed. Since the incremental evaluation method carries its advantage, the method itself is very important when considering the execution efficiency of the program developing environment. This paper extends the dependency chart for an imperative language and presents the extended version of dependency chart which can be applied to the Object Oriented Programming Languages such 'Java'. This paper also presents the incremental evaluation algorithm for Object Oriented Programming Languages and proves its correctness, analyzing the efficiency of incremental evaluation by the simulation.

Software development process evolves by component based development(CBD) process and introduction to configuration management system is risen recently. In this paper, we explained component configuration management system evolved out of CBD methodology and focused on the specification management in component configuration management. The component specification is being based on XML that is a normalization document. Also, component version management and dependency management are achieved by a component name. And component dependency information is just the integration information using a component specification name used in the composition when component specification is composed. Thus we confirmed possibility of version management and dependency management using the specification.
