As the environments of world economy have been changed so rapidly, the conditions of marketing and distribution also have been altered. In korea distribution industry has been changed according to the introduction of various patterns of distribution and marketing. Among them the emerging of network marketing, same meaning with multi-level marketing in this research, is a important phenomenon of distribution industry in Korea. Not only it contributes the progress of national economy, especially distribution industry, but also it includes some limitations and criticism from the dissenters. In this paper, the clear definitions and characteristics of network marketing are suggested. And the current situations of network marketing in this country has been analyzed and compared, The future perspectives and problems of this network marketing have been diagnosed and classified for the future development and contribution for national economy. The various alternatives for the future development of network marketing have been studied and suggested in terms of each role of this industry such as distributers, consumers and government. Though this paper has a small contribution, it contains many limitations for research. Therefore it suggest future directions for further research.

Design factors such as design objects establishment, analysis, synthesis, production, test and evaluation should be educated in a systematic way. Also design ability to reflect practical restrictive conditions such as industrial standards, economic feasibility, environmental impact, aesthetics, safety and reliability, ethical impacts and social impacts should be cultivated. In this paper, we explain the meaning of these terms and propose a systematic engineering design education framework satisfying Korean engineering education accreditation criteria. We also present a simple implementation in information network engineering.

This study is about the influence of authors' centrality on research outcomes in a large-scale collaborative research network. Using the social network analysis method, five types of centralities were derived. Six research outcomes of individual researchers were also derived through bibliographic information of the social science field for the last 10 years. A multivariate regression analysis was conducted to examine the causal relationship between the centrality and research outcome, and the effect of centrality on research outcomes was found to be statistically significant. The result of this study shows that the revised citation and H-index significantly influenced the authors' centrality. This result can imply that the centrality of the researcher can expect a considerable influence of the thesis as well as a certain level of productivity. The meaning of this study is to analyze the effect of centrality on the research outcomes of the large-scale collaborative research network in the past decade, and is carefully to suggest a guideline in order to support new research information services for active researchers and the advancement of collaborative research. This study has its limitation for interpreting the diverse academic fields of the social sciences in a uniform way. In future study, it is necessary to conduct studies using various weighted indices for network centrality in order to measure the influence of research.

A "task network" is a type of social network that consists of experts who exchange professional help and advice regarding executing tasks. In this study, we investigate the task network used within the IS department of a national bank in Korea. We identify how this network moderates the influence of computer-mediated communication (CMC) technology on an individual s task performance. Size, density, and centrality were measured as the characteristics of a personal task networks. Size equates to the total number of colleagues who work with a specific member for a certain project. Density is the ratio of the number of actual relationships to the total number of available relationships. Centrality defines whether an individual s position is in the exact center of whole network, and is measured by betweenness centrality, meaning the position one member holds between others in a network. Our findings conclude that the conditions - the larger the size of the task network, the smaller its density and the higher its level of centrality - lead to more benefits of using CMC media. Further, this positive effect of CMC is more noticeable when it provides synchronicity.

As an attempt to consider what to pay attention to in science learning, this study was conducted with the aim of discussing the meaning of science learning as a heterogeneous network. As a result of theoretical investigation, the characteristics of the heterogeneous network were described in three aspects: heterogeneous composition, existence by relations, and construction and change by translation. And it was discussed that science learning also has these characteristics of heterogeneous network. Relating to what to pay attention to in science learning, it was also discussed that science learning as a heterogeneous network requires us to pay attention to the elevation of things, the concept as a punctualized heterogeneous network, and the construction and expansion of heterogeneous network with neonadeuri of 'unripe' and 'ripe'. Finally, several suggestions for the science learning were given.

In the post-genomic era, researches on proteins as well as genes have been increasingly required. Particularly, work on protein-protein interaction and protein network construction have been recently establishing. Most biologists publish their research results through papers or other media. However, biologists do not use the information effectively, because the published research results are very large. As the growth of internet field, it becomes easy to access these research results. It is important to extract information with a biological meaning from various media. Therefore, In this paper, we efficiently extract the protein information from many open papers or other media and construct the database of the extracted information. We build a protein network from the established database and then design and implement various pathway analysis algorithms which find biological meaning from the protein network.

An extended form of lexical network is explored by presenting U-WIN, which applies lexical relations that include not only semantic relations but also conceptual relations, morphological relations and syntactic relations, in a way different with existing lexical networks that have been centered around linking structures with semantic relations. So, This study introduces the new methodology for constructing a syntactic relation automatically. First of all, we extract probable nouns which related to verb based on verb's sentence type. However we should decided the extracted noun's meaning because extracted noun has many meanings. So in this study, we propose that noun's meaning is decided by the example matching rule/syntactic pattern/semantic similarity, frequency information. In addition, syntactic pattern is expanded using nouns which have high frequency in corpora.

Background: The publicness concept in healthcare has been built to its social consensus relying on historical context, with the result that the meaning of publicness has a great diversity and heterogeneous nature in Korea. Thus it needs to be addressed to clarify the meaning and boundary of the publicness concept in healthcare, so as to discuss its social implication. Methods: In order to investigate whether or how the publicness concept is used in healthcare, we conducted a text network analysis in 779 news articles from 8 Korean daily newspapers over a recent 5-year period. Results: The publicness concept was closely related to medicine and medical institution, and formed a conceptual network with public health, medicine, welfare, patient, government, Jin-ju city, and health. Keywords relating publicness tended to be similar between four major newspapers; however, the association with Jin-ju city, government, and society was noticeable in Kyunghyang Shinmun and Hankyoreh, and so was patient and service in Dong-A Ilbo. Conclusion: Publicness and medicine was closely associated, and government seemed to remain as a main actor for public interest. Publicness was related with a variety of actors and values, with its expanded boundary. The different contexts of publicness by newspapers might reflect each ideological inclination. The textual importance of publicness was relatively low in part, which suggests that publicness was used in a loose sense or as a routine.

This paper analyzes the meaning of sustainability in sustainable development in the ecological ethics, and suggests the importance of ecological sustainability. In the discussion of ecological sustainability the relation between sustainability and change should be regarded as not conflictual but interactive. The concept 'ecological' in this context means network, and the concept 'sustainability' means the relationship between changing being(or beings) which constitutes ecological system and its unchanging being(or whole relation). So there are two axes of human and ecological system, and three elements namely network which means mutual dependence of human and nature, sustainability which means the maintenance of ecological relations, and responsibility which humans should take for the sustainability, in the ecological sustainability. The maintenance between being and relations of beings, changing sustainability, the priority of being to non-being, mutual interdependence on the basis of solidarity of beings are important values in the ecological sustainability.
