Efficient scheduling for software development is a major concern for software engineers. A industry simultaneously performs a variety of projects with the limited resources without overdue. A way to overcome the limitation of resources is sharing of the resources through the projects. This study discusses the matrix organization for software development. A scheduling for matrix organization is a special case of project management problem. The ultimate goal of scheduling problem in this study is to reduce the overall duration of the multiple projects. A genetic algorithm is presented to solve the scheduling problem of the matrix organization and is substantiated with numerical results.

Nowadays many companies expect to apply knowledge management mechanism for the explicit business performance improvement. Because peoples who employees are the understanding of knowledge contribution in the organization should try to achieve goal through the effective knowledge management activities. The purpose of this study is to examine the effect of major factors to support the performance of knowledge management in the company by using structural equation modeling. From the empirical result of this study with 485 leading corporation in Busan, we came to know that the infrastructure of knowledge management has influence on knowledge sharing and creating mechanism related to knowledge management activities. And, the knowledge management activities has positive influence on internal and external customer' satisfaction, and firm's social responsibility.

In today's engineering world, any product development activity requires the expertise and the interaction of many different engineering. Therefore the various activities in a product development architecture are highly distributed and interdependent. The interdependence may be due to sharing of databases and transfer of information between various activities. This will require an integrated product model. That can support distributed design such that participants from different backgrounds collaborate towards one common goal. This paper presents the architecture of the product modeling system for the integration of CAD and CAE. It then reports on the study of STEP 10303 and UG open API focused on the integration of different technical environments.

In IoT(Internet of Things) environment, users want to receive customized service by users' personal device such as smart watch and pendant. To fulfill this requirement, the mobile device should support a lot of functions. However, the miniaturization of mobile devices is another requirement and has limitation such as tiny display. limited I/O, and less powerful processors. To solve this limitation problem and provide customized service to users, this paper proposes a collaboration system for sharing various computing resources. The paper also proposes the method for reasoning and recommending suitable resources to compose the user-requested service in small device with limited power on expected time. For this goal, our system adopts MBTI(Myers-Briggs Type Indicator) to analyzes user's behavior pattern and recommends personalized resources based on the result of the analyzation. The evaluation in this paper shows that our approach not only reduces recommendation time but also increases user satisfaction with the result of recommendation.

The power of the internet community as a social network exerts great influence on all areas of our society not only on knowledge creation and knowledge sharing but also on politics, economy, and culture. This study aims to investigate how the diffusion process of information evolves on the internet in the new environment. The focus of the study is particularly on aspects of using information and the process of information production and the types and methods of online communities. It is the goal of the study to clarify aspects of the online community as an important mediator among universal means of communication in our society. Ways of social communication are changing rapidly and thus the reasoning for this change is very important policy issues to form a social consensus.

Since 1974, the first subway is constructed in Seoul metropolitan area, from 1985 country metropolitan subways have been built. But most country metropolitan subways cannot reach the goal of transportation sharing ratio and show a loss. In this paper, I investigate the issues of country metropolitan subways and present the methods to improve them focusing on strengthening transit network. At first, it is introduced that the method can complement incomplete network from insufficient subway lines. And I propose the consolidation method using KORAIL railway lines. Finally, the connecting method into subway missing area is presented with various transit systems like BRT, Guideway Bus and single railway line extension.

For decades, thousands of corporation introduced knowledge management systems to respond knowledge-based society. However, it seems that the systems merely focusing on knowledge accumulation and its sharing have been bounded by many restrictions in terms of new knowledge creation based on the life cycle of knowledge management systems. Moreover, recently, a variety of knowledge management activities regarding organization, systems, and process is emphasized as a strategic asset for a corporation to create core knowledge. Therefore, this study adopted the Csikszentmihalyi's flow theory to investigate the factors affecting knowledge creation and the success factors of knowledge management systems in virtual space. Prior studies argued that flow experience should be a prerequisite for creative knowledge creation. In that vein, this research revealed the causal relationships for flow experience between the determinants of clear goal, immediate feedback, congruence of challenge and skill. Additionally, it empirically examined how flow experience affected the exploratory behavior of knowledge creation.

This study examined the influence of lexical factors on verbal Eojeol recognition. To meet the goal, forty-five L2 Korean learners and twenty-two Korean native speakers took Eojeol decision tasks measured with the lexical factors such as 'number of strokes', 'number of consonants and vowels', 'number of syllables', 'number of morphemes', 'whole Eojeol frequency', 'root frequency', 'first-syllable-sharing frequency', and 'number of dictionary meanings.' As a result, 'whole Eojeol frequency' was the most effective factor to predict Eojeol recognition reaction time for native speakers and L2 learners, which supports the full-list model. Other lexical factors influencing Eojeol recognition reaction time in L2 learners were different following their proficiency level.

Various hyper-intelligent and ultra-realistic data-driven services are being increasingly developed with the goal of achieving a hyper-connected intelligent society. To sustain this trend, our research focuses on the integration and optimization of data-driven applications from several aspects such as delivery, storage, execution, and sharing of data and software, beyond the limitations of the existing network infrastructure. In this paper, we present important research issues of data-centric hyper-distributed autonomous infrastructure technologies.

In recently, the SNS which is the hot issue of the knowledge-based information age use various goal based on human networking. This service construct a human relationship which exchange of information and opinion freely, and can extend the human network relationship using open his profile and closeness others. But, each individual's privacy invasions and pissing based on information open and sharing are rising. In this paper we present a method of protecting the SNS group's communications and information interchangeability efficiently.
