Robot design serves as the crucial link between a human and a robot, the cutting edge technology. The importance of the robot design certainly will be more emphasized when the consumer robot market matures. For coexistence of a human and a robot, human friendly interface design and robot design with consideration of human interaction need to be developed. This research extracts series of functions in need which are consisted of series of case studies for planning and designing of 'A Shopping Support Robot'. The plan for the robot is carried out according to HRI aspects of Design and the designing process fellows. Definite results are derived by the application of series of HRI aspects such as gestures, expressions and sound. In order to verify the effectiveness of application of HRI aspects, this research suggests unified interaction that is consisted of motion-capture, animation, brain waves and sound between a human and a robot.

This study is subway station canopy evaluation to improve the landscape of a street furniture design. From a survey of the professional abstracted the design elements of subway station canopy in Daegu. And then, it practiced a canopy design appreciation by the analysis of appreciation items. The results are as follows. First, this research analyzes each quality a classified by the four characteristics at the subway station. In general station case, the slope roof was consistent in used to be unified. If the symbol of the express station wasn't common in cross-section or material. In addition, the design evaluation in the lower canopy were evaluated. Therefore, in case of the city installed in the canopy, the characteristic of city gateway and the symbolic characteristic of a design that is required. Second, subway station canopy existed in widely opened site come out a lower rating about safety. Therefore, considering the safety light device or system need to do. Third, if the horizontal or sloping roof shape come out in a lower rating, the highly evaluated curve shape is considered to apply. Forth, a structure material of the canopy was highly evaluated the aluminum composite panels and structural steel pipes. Therefore, to improve a beauty of the city, to give rhythm to a structure material of the canopy of the aluminum composite panels and structural steel pipes will be desirable to use as the main ingredient.

Recently, application area on the Location Based System(LBS) is increasing because of development of mobile-communication and GPS technique. Previous studies on the index of moving objects are classified as either index for past trajectories or current/future positions. It is necessary to develop a unified index because many applications need to process queries about both past trajectories and current/future positions at the same time. In this paper, the past trajectories of moving objects are represented as line segments and the current and future positions are represented as the function of time. We propose a new index called PCR-tree(Past, Current R-tree) for unification of past, current and future positions. Nodes of the index have bounding boxes that enclose all position data and entries in the nodes are accessed with only one interface. We implement the proposed index and show a feasibility of processing the queries about temporal-spatial domain with the query tool which we develop.

This study intends to gather terminology as a first step for encyclopedia of furniture from four areas such as traditional Korean furniture and architecture, modern and contemporary furniture, wood science, and wood culture by each expert. Since China, Japan, America, and European countries have chronologically influenced domestic furniture culture, the furniture terms are currently used by mixed languages such as Chinese characters, Japanese, English, Russian, Korean, etc., in the furniture fields and education. Domestic furniture companies and schools have had lots of difficulties in carrying out works due to the furniture terms not unified. This paper carried out through domestic furniture fields, internet, and furniture books from the inside and outside of the country, including the references of architecture, interior, crafts, and wood science and culture in order to research the terminology, results in the confusing language use of furniture terms at the furniture companies, schools for furniture education, and wood workshops having their own furniture terms. Therefore, for unified and standard furniture terminology, the terms gathered must be reviewed and conformed through the committee composed with the relevant experts so that it will be able to help the relevant business and education carry out their work better.

According to the development of service industry recently, the use of call taxi service is increased to use a taxi more comfortably. But related firms hesitate to construct a call center on account of enormous expense of constructing. Hence we developed the system that can minimize expense of constructing a call center which use a cellular phone. The proposed system is different from the existing call system of using a terminal method. we designed by applying UML(Unified Modeling Language) the system that can integrate and manage operations of customer management, driver management, order management and settlement of accounts etc. more efficiently using CTI(Computer Telephony Integration). Then the designed system is constructed by using Visual Basic 6.0. For implementing CTI more effectively, calling number of customer is received in PC using CID that is commercialized and then the customer's information is retrieved in the Database in real-time. The system proposed in this paper is possible to construct at low expense, can improve customer service level through an efficient customer management solution.

It is more emphasized on the software architecture recently, as the scale of a software becomes huge and the need of the software management becomes more dynamic. Software architecture is a representation of structures of software framework just like the blueprint of building architecture. In order to describe software components and their relationships accurately and entirely, software architecture is documented in some different views, by using of modeling tools. UML(Unified Modeling Language) is a software modeling tool recently used for documentation of software and as well as software architecture. Nevertheless, what we have to agree with is that UML is not easy to use and its standard changed continuously. And also the documentation with UML is found some burden because of its difficulties in learning and using. This inconvenience enforces us to purchase and use commercial tool for UML. The study introduces the architecture views refined from 4+1 Views for architecture design and shows how to represent architecture views for software architecture. Especially, we simplifies UML diagrams for the purpose of focusing on architecture views and facile manipulation. At the end, we add the evaluation on the refined architecture views as well as refined UML diagram.

UML class diagrams are used to visualize the static aspects of a software system and are involved from analysis and design to documentation and testing. Software modeling using class diagrams is essential for software development, but it may be not an easy activity for inexperienced modelers. The modeling productivity could be improved with a dataset of class diagrams which are classified by domain categories. To this end, this paper provides a classification method for a dataset of class diagram images. First, real class diagrams are selected from collected images. Then, class names are extracted from the real class diagram images and the class diagram images are classified according to domain categories. The proposed classification model has achieved 100.00%, 95.59%, 97.74%, and 97.77% in precision, recall, F1-score, and accuracy, respectively. The accuracy scores for the domain categorization are distributed between 81.1% and 95.2%. Although the number of class diagram images in the experiment is not large enough, the experimental results indicate that it is worth considering the proposed approach to class diagram image classification.

Recently, the number of people wishing to return to farming is increasing, However, the lack of farming experience and management information of returnees is one of the main reasons for increasing the probability of agricultural failure. This study proposes an interface to support early facility cultivation management decision-making for returnees who want facility cultivation. The proposed interface is designed with UML(Unified Modeling Language) and provides key decision-making information such as land/crop suitability, land/facility costs, and management costs according to input data such as cultivation areas, selected crops, and cultivation types selected by the user. Through the proposed interface, facility cultivators can effectively and quickly acquire initial decision-making information for facility cultivation in the desired target area.

In this paper, union-based rule antecedent neuro-fuzzy controller, which can guarantee a parsimonious knowledge base with reduced number of rules, is proposed. The proposed neuro-fuzzy controller allows union operation of input fuzzy sets in the antecedents to cover bigger input domain compared with the complete structure rule which consists of AND combination of all input variables in its premise. To construct the proposed neuro-fuzzy controller, we consider the multiple-term unified logic processor (MULP) which consists of OR and AND fuzzy neurons. The fuzzy neurons exhibit learning abilities as they come with a collection of adjustable connection weights. In the development stage, the genetic algorithm (GA) constructs a Boolean skeleton of the proposed neuro-fuzzy controller, while the stochastic reinforcement learning refines the binary connections of the GA-optimized controller for further improvement of the performance index. An inverted pendulum system is considered to verify the effectiveness of the proposed method by simulation and experiment.

To ensure stable urban flight of electric vertical take-off and landing(eVTOL) aircraft, securing handling qualities and stability is essential. However, clear handling qualities standards for eVTOL aircraft, which have different characteristics from conventional manned aircraft, have not yet been established. Therefore, this paper identifies handling qualities evaluation criteria suitable for eVTOL aircraft based on the handling qualities standards for manned aircraft and designs a control system that meets the predicted handling qualities criteria through evaluation. simplified vehicle operation(SVO) control laws and stability and control augmentation system(SCAS)-based control laws were applied to the lift-cruise configuration eVTOL aircraft. Using control designer's unified interface(CONDUIT), it was confirmed that the level 1 standard was met, and to validate the system, assigned handling qualities evaluation was performed using handling qualities task elements(HQTE) in an X-Plane based simulation environment, resulting in the design of a control system that ensures handling qualities.
