This study proposes evaluation dimensions of object-oriented systems modelling tools and activities available in object-oriented systems development practices. The dimensions ale developed based on previous research in cognitive psychology, information systems modeling study, and object-oriented systems analysis arid design areas. The proposed dimension is composed of two dimensions. The one dimension includes abstraction levels of modelling and the other includes process and representation in modeling activities. Experts on object-oriented modeling were selected to evaluate the practical validity of the proposed dimensions and applications of major object-oriented modeling tools during systems development project. Most of the tools were observed to be used for representing objects rather than for modeling the process of related objects. The proposed modeling dimension will be evaluated for acquiring general validity in future empirical research.

This study explores the level of designer brands' market oriented attitude through a conceptual framework of market orientation. Designer brands have rapidly increased in the Korean fashion market with a competitive environment that pushes designers to improve market oriented attitudes and strategy. Designers working for 20 brands that the government designated as 'promising creative designer brands' were invited for in-depth interviews, 19 designers from 18 brands participated in this study. The generation of market intelligence that composes market orientation meant that the designers were confirmed to collecting different types of information according to information sources. They showed interest in collecting information on the exploration of design trends from overseas designers as well as operational and managerial information from domestic designers. Fashion-related stakeholders mainly collected feedback on design concepts from the press and public institutions. They collected customer feedback from buyers; however, appropriate feedback was inadequate. Designers generally appeared to place less value on the collection of customer responses and opinions; however, two groups of designers showed customer-oriented attitudes according to accumulated experience. The market-oriented attitude of top designers had an important role in designer brands; consequently, top designers should be properly trained to improve market-oriented attitudes to increase market performance.

Software quality is classified by quality of process and product. In experience of Quality Management, it is known that quality level of product as it depends on goodness and badness of process and organization. As a result, improvement of software process has been important subject. According as this trends, ISO 12207 is publicated as standard of software life cycle process by ISO. For UML based object oriented development process, it is necessary that we should research detailed definition of activity and task of ISO 12207 process which is added, deleted or tailored in according to organization and project characteristics. In this thesis, by according with ISO 12207 software life cycle process, UML based object oriented development process is proposed. This process is composed of 7 steps and 19 activities including development phase, activity and product to improve quality of reliability. Usefulness of object oriented process for improvement of software quality is proved at three ways, which are comparative analysis of process characteristics, SPICE process evaluation and SPICE rick analysis.

While object-oriented models are effective in achieving sharing and code reusability, they unfortunately lack a mechanism for giving scope to objects. We revisit an object-oriented model in which each object can be given a scope. We illustrate the usefulness of this model by showing that it supports the notion of parameterized modules without difficulty.

Issues on design of routing scheme and routing metric for multicast in multi-channel multi-radio (MCMR) wireless mesh networks (WMNs) are discussed. Emphasis is placed on channel-diversity oriented routing metrics. From case study the conclusion to be drawn is that the key for design of channel-diversity oriented routing metrics is how to construct an optimization function to quantify interdependence between channel assignment and multicast routing throughput.

Increasing affectability of high-speed Internet and convenient access devices has made the Internet a major source of information search and sharing. As the provision of information has rapidly becomes an important and viable business model, the objective utility and marketability of information contents have become a focus of interest among many academicians and managers. Researchers have traditionally focused on the design of the interface, availability of resources, network accessibility, the format of web sites and their underlying systems. However, the usefulness of contents has been left as a little explored issue. To correctly diagnose and pursue the viability of contents provision business a shift of perspective is required : a shift from technology-oriented perspective toward user-oriented perspective, and a shift from form and design focus toward content focus. This research attempted to analyze consumer-oriented information quality in a more systematic way by focusing on a limited domain travel-related information contents. We proposed a relationship among consumers'behavior, characteristics of information, and the values of information measured by users. An empirical examination of the model was performed using a survey on Internet users in Korea. Implications are drawn for managers responsible for creating marketable contents.

Purpose: This study aims to investigate the impact of two types of information quality, which are platform-oriented information quality and customer-oriented information quality, on customers' decision-making processes in the Online to offline (O2O) platform environment. Grounded in the product brokering efficiency model, which encompasses screening cost, evaluation cost, and decision quality, a model framework was developed. Furthermore, this study explores how these decision-making processes affect customer loyalty. Methods: Given that food delivery apps are the most widely used O2O service in Korea, this study targeted users of these apps for data analysis. We conducted hypothesis testing through a purposive sampling methodology focusing on food delivery app users. A Partial Least Squares Structural Equation Modeling analysis was conducted to analyze the data. The data collection occurred via an online survey from October to December 2021, with a total of 212 respondents participating. Results: The results of this study revealed the significant role of information quality in helping customers' decision processes while using food delivery apps. Specifically, it was found that platform-oriented information positively influences decision quality, while customer-oriented information significantly affects both the reduction of evaluation cost and the enhancement of decision quality. Additionally, the study indicated that lower evaluation costs and higher decision quality lead to increased platform loyalty. However, a reduction in screening cost did not have a significant impact on platform loyalty. Conclusion: While previous studies have overlooked the existence of two sides, service provider and user, in a platform, this research holds significance in its analysis of how information quality impacts loyalty by utilizing the two kinds of information quality. Practitioners can enhance customer loyalty to the platform by enriching customer-oriented information, thereby reducing customers' evaluation costs and encouraging more loyal usage of the platform.

Object-Oriented design method decomposes the program into object that establish the relationship between objects. It is the technique of object centered decomposition unlike function oriented legacy system. Since existing Object- Oriented design method doesn't fully explain of the design method of module and decomposition, and need to implement the Object-Oriented software as a total system init. It has many problems that whole object design method and application programs should be analyzed for the understanding an Object-Oriented software component. Therefore, this study provides a procedure for Object-Oriented module design and criteria of decomposition to practically support the complex and large system development. Futhermore, it shows a consistency between design model and implementation through a case study applying these module decomposition criteria to the real system.
