This study researched that the remodeling was executed desirably in the side of deweller's household to the subject of ten apartment housings located in Gwang-ju, Jun-nam province. The study method was used the field study method and used in parallel with participant observation. As a result of the study, first, the problems of remodeling enforcement process are brought about standardized design, bad construction and the difficulty of solution in the defect occurrence. Second, By that request of the household is not reflected, the room except bedroom and the bathroom of inner room are low practical use degree. And wash space, garden space, assistant space of kitchen work were becoming hindrance factor of the residing environment because the use is irrational.

The roll Pass design is one of the most important processes to design the whole equipment of the rods and bars rolling system. In this study, the roll pass design program named TollRo(Rolling Factory Organizer) was developed. conventional methods to design roll pass were analyzed and a new algorithm to design the dimension of the intermediate groove was introduced. Object oriented programming technology was implemented in this design program. It comprises GUI(Graphic User Interface), function of automatic pass design, function of modifying pass schedule and database of material properties. The developed program can be used to design roll pass with consistency for the rods and bars rolling system. The man-hours for the whole design can be drastically reduced. The design parameters of rolling system can be extracted quickly by this program.

The current user interface (UI) of NEIS school affairs business system is not efficient in conducting the business because of complicated data input forms as well as unharmonious connection between similar items and functional menu. In the paper, the term UI means a comprehensive concept including input/output, input/output related functionality, and menu configuration for users to perform their tasks. The first survey, carried out with one hundred teachers at three elementary schools of Kyeonggi-do, shows that the UI problems of the system are manual inputs, inconvenient menu configuration, disconnection between academic calendar and educational process, complexities of managing attendance report and curriculum evaluation, etc. We have improved the UI design by providing more efficient input method and more systematic menu configuration compared to the current system, and then evaluated the design through the second survey. Evaluation results show that users prefer the proposed UI design especially from the viewpoint of user-friendly input interface and user-oriented view composition.

Design traceability has been widely recognized as being an integral aspect of software development. Also many projects for software application development have failed because that the projects did not analyze user requirements sufficiently and reflected them in the projects adequately. This thesis proposes a specification and tracing technique for object-oriented analysis and design. The subject of this study is the artifacts of UML development methodology. Therefore, to improve the quality of the software development cycle, in short, the system requirement of customers will be able to respond quickly.

A connected car's major factor is connectivity and it can be applied for new concept smart PC hardware and software design method of digital virtual assistance using voice recognition engine at server when infotainment functions are implemented because internet connecting LTE or 5G wireless mobile communication is always is possible. In this paper, a hardware architecture of smart auto-PC and software architecture based on GENIVI platform, and necessary functions are proposed. Also an effective analysis and design method of connected car infotainment system will be presented by showing user requirement analysis using object-oriented method, flowchart and screen design.

This thesis implements retrieving systems with easy to retrieve photos which end-user want to find based m end-user computing(EUC)'s a theoretical study on factors in exert a effect on the computing systems. And also this systems allow a photographer to store his works in the database of this systems by himself on internet environment. This sock photo systems is developed with object oriented design methodology so it is easy to modify and to reuse software. And this systems can use for electronic commerce by adding the electronic payment systems.

Digital technology With the popularization of computers and IT technology development is causing a dramatic change across the human life. Increase of profit in fashion industry has a significant impact on the overall industry. It has been studied to develop consumer oriented higher value-added fashion products of including clothes using digital technology abroad. In this paper, we propose a system that when user stand in front of display, user can show body captured depth camera look the coordination of a variety of costume and fashion concept through a magic mirror. Using the system, we will satisfy the convenience of user and be used as a way appropriate to clothing shopping in the shortest time. The system will develop personalized fashion content industry enhanced interaction.

In this study, we propose an ensemble engine, which is a framework for game engine optimized for visual novels genre, focusing on storytelling among various game genres. The game of Visual Nobel genre is based on multi-ending story and features branching of various scenarios according to user's choice. The proposed engine supports various multi-scenarios and multi-endings based on nodes according to the characteristics of these genres. In addition, it provides a convenient and intuitive user interface that not only enhances user immersion but also provides VR function to maximize the sense of presence. We will demonstrate the usefulness of the proposed game engine by designing the framework of a game engine suitable for this feature and actually creating variety stories automatically.

In this paper, we propose an efficient car management system based on object-oriented modeling using car number recognition and smart phone. The proposed system perceives car number of repair vehicle after recognizing the licence plate using an IP camera in real time. And then, existing repair history information of the recognized car is be displayed in DID. In addition, maintenance process is shooting video while auto maintenance mechanic repairs car through IP-camera. That will be provide customer car identification and repairs history management function by sending key frames extracted from recorded video automatically. We provide user graphic interface based on web and mobile for your convenience. The module design of the proposed system apply software design modeling based on granular object-oriented considering reuse and extensibility after implementation. Car repairs center and maintenance companies can improve business efficiency, as well as the requested vehicle repair can increase customer confidence.

Objective: This paper targets a framework of a hand gesture based interface design. Background: While a modeling of contact-based interfaces has focused on users' ergonomic interface designs and real-time technologies, an implementation of a contactless interface needs error-free classifications as an essential prior condition. These trends made many research studies concentrate on the designs of feature vectors, learning models and their tests. Even though there have been remarkable advances in this field, the ignorance of ergonomics and users' cognitions result in several problems including a user's uneasy behaviors. Method: In order to incorporate compatibilities considering users' comfortable behaviors and device's classification abilities simultaneously, classification-oriented gestures are extracted using the suggested human-hand model and closed-loop classification procedures. Out of the extracted gestures, the compatibility-oriented gestures are acquired though human's ergonomic and cognitive experiments. Then, the obtained hand gestures are converted into a series of hand behaviors - Handycon - which is mapped into several functions in a mobile device. Results: This Handycon model guarantees users' easy behavior and helps fast understandings as well as the high classification rate. Conclusion and Application: The suggested framework contributes to develop a hand gesture-based contactless interface model considering compatibilities between human and device. The suggested procedures can be applied effectively into other contactless interface designs.
