So far, various researches have been conducted on evaluation of e-learning software, but subjective evaluation criteria are formed according to the classification presented from the viewpoint of the researcher rather than systematized form according to related standards. In addition, standards for software evaluation are continuously being supplemented for practical use, so it is urgent to establish evaluation bases by establishing evaluation criteria. Therefore, in order to establish the quality evaluation standard of e-learning software, this study analyzes the quality requirements of e-learning software based on the usability system among the quality characteristics of ISO/IEC 25000 series. This evaluation standard is distinguished by the fact that the evaluation standard of e-learning software that reflects the latest trend of related standardization has been established and practical utilization has been improved. It can be used effectively for quality evaluation and certification of e-learning software in the future.

This study is to organize the manual for the safety accidents in campsite. For this, analyzing the types of safety accidents and reviewing the regulations of campsite. Through theoretical considerations, the problem was diagnosed and the elements of improvement were presented. Eventually, part of the Responsive and Preventative Behavior manuals were developed to organize 'Preparation Behavior Manual'. Especially, examples of safety accident prevention behavior manual were divided into: 1st, suffocation, 2nd, traffic accident, 3rd, fire, 4th, and electrical accident. "S.A.F.E.", An example, was created with the accident specific initials that were more frequently caused. Furthermore, it was emphasized that it is necessary to process of understood by the user. Subsequent studies recommended the study of cases, improvement of safety management indicators, and the specialization of campground manager and safety guard.

The goal of U-Eco City testbed is improving the technical completion of ubiquitous technology/Services which have been developed in other core projects in U-Eco City, by implementing newly developed ubiquitous technology/Services to testbed. When the newly developed ubiquitous technology/Services are implemented in the testbed, we will monitor whether the developed ubiquitous technology/Services can be applied in the real situation and if they have problems we will find out the solution to solve the problems. Final goal of this reaserch is framework development for the U-Eco City construction guideline. We developed the framework development for the U-Eco City construction guideline by i)analyzing steps for construction of U-Eco City, ii) analyzing details of each steps for construction of U-Eco City, and iii) including results of research which have been developed in other core projects in U-Eco City.

Throughout the nation, each local Agricultural Cooperative (AC) has built its own agri-products processing factory in order to provide the steady demand source for the locally produced agri-products. However, each factory of AC has performed poorly with no competitive advantages against the national brands of private companies. Thus, from the perspective of the National Agricultural Cooperative Federation (NACF), the current situation of unorganized and inefficient management of the factories under the control of each local AC needs to be improved. In this case analysis, we introduce the problems of the AC factories and discuss the NACF's approach to solve the problems. In particular, given that AC as well as NACF are the non-profit organizations, it is worthwhile to fay special attention to the process of restructuring the system of distribution channels for the processed agri-products with the concept of marketing.

Existing railway bridges have been going through various improvements since the past, with new improvement plans being formed based on social and technological demands. However, there is the need, above all, for an efficient execution plan due to the great number of sites and excessive amount of required expenses contrary to limited assets. The system itself must be held in question in order to systemize various improvement plans, to define and describe factors while utilizing evaluation methods for significance and correlation to achieve generalization. This paper is focused on determining the priority of various improvement plans through the optimization selection process of mutually evaluating alternative plans under various evaluation standards, thus corresponding to the decision-making purpose. The AHP analysis technique was applied for systemization setting and preference evaluation, while the HPT procedure was applied to develop and select appropriate improvement plan factors.

A folksonomy is a new classification approach for organizing information by users to freely attach one or more tags to various resources published on the web. Recently, in order to provide useful services and organize the folksonomy data, many collaborative tagging systems based on folksonomy offer additional functionalities for grouping each elements of a folksonomy. In this paper, organization framework for grouped folksonomy is proposed. That is, we suggest the grouped folksonomy model that is an extended folksonomy with the concept of "group" and fundamental operations(Group Aggregation, Group Composition, Group Intersection, Group Difference) for grouping of folksonomy elements. Also, we developed a supporting tool(GFO) that constructs grouped folksonomy and executes fundamental operations. And we introduce some cases using the fundamental operations for grouping of each elements of folksonomy. Based on suggested our approach, we can construct grouped folksonomy and organize and extract useful information from the folksonomy data by grouping each elements of a folksonomy.
