Traditionally, simulation method is used to test and evaluate the performance of communication protocol or functional elements for mobile communication service. In this paper, wireless network simulator is implemented using the C++ object-oriented programming language. This simulator can simulate wireless data services, like as ad-hoc networks, by considering the user's mobility. In this paper, the simulator includes network traffic model to reflect wireless data service and traffic source model to represent a user's mobility similar to real service environment and traffic characteristics can be reflected on the simulation, and also more accurate simulation results can be got through that. In addition, by using object-oriented techniques, new service feature or environment can be easily added or changed so that the developed mobile communication simulator can reflect the real service environment all the time. This simulator can be used in adjusting the characteristics of wireless data hosts following the mobility of the user, and also can be used in building new wireless ad-hoc network routing protocols.

This study was intended to investigate the satisfaction degree of users with ward design, and on the basis of this, to suggest the design guidelines of user-oriented general hospital ward. A general hospital in Busan was case-studied. Subjects were 49 patients, 50 families, 50 nurses in this hospital. The results were as follows; The satisfaction degree of users with the psychological factors of ward design was relatively low, while the user satisfaction degree with the functional aspects was relatively high. As for the difference among users, the satisfaction degree of patients and their families with the functional aspects of ward design was higher than that of nurses, and there were no many cases to show the difference among users' satisfaction degree with the psychological factors.

Since the guaranteed service quality(QoS) is spotlighted as a strategic competitive tool to Broadband Convergence Network(BcN) service providers, many scholars have dealt with QoS issues in the BcN environment. However, just a few researchers focus on end-users and most are lean toward service providers or technology itself. In this paper, therefore, we investigated how end-users could measure service quality in the BcN environment, and moreover, proposed the end-user oriented measurement guideline for BcN QoS. Through literature review and two surveys, four QoS dimensions and nineteen measurement items were derived from end-user's perspective. proposed QoS dimension and items would be utilized as meaningful tools for future BcN service.

This paper describes a design model for the conceptual design of ships. Existing design models have problems such that their operating mode of batch versions cannot reflect the design procedures in reality. Reliability of the results is low because the performance estimations are based mainly on empirical formulas. To improve the problems of existing design models, a new design model has been developed. The new model consists of an interactive user interface, a database of main engines, a database of particulars of existing ships, and ten modules for performance estimations. To develop such a user-oriented system, the concept of graphical user interface (GUI) is adopted.

Living labs are an increasingly popular methodology to enhance innovation. Living labs aim to span boundaries between different organizations, among others Triple helix actors, by acting as a network organization typically in a real-life environment to foster co-creation by user-groups. This paper presents critical factors of Living labs in boundary-spanning between Triple Helix actors. Derived from a mixed-method approach and applications in the healthcare sector, the three main critical factors turn out to be 1) an adequate user-group selection and involvement, specifically a rich interaction and absorption of its results, 2) a balanced involvement of all relevant actors, and 3) a sufficient (early) attention for values, both values of user-groups and values of the management. People-oriented Living labs tend to differ from institution-oriented Living labs regarding these critical factors. Further, universities tend to take on diverse roles and strength of involvement, while the business sector tends to be actively involved only if this has been set as an explicit aim at start. The paper closes with a summary and future research paths.

This research investigates a kill probability model for the performance evaluation of guided missile system, and also develops graphical user interface for the input and output of the model based on the visual object-oriented programming application. The major simulation events used in this research are missile guidance homing point, burst points, and kill mechanism(direct kill, blast kill and fragment kill). For the user interface, we also design and implement the visualization system that can show the graphic style of the kill probability attained by the model. The results of sample run are shown, but these could be improved to be better with visual simulation which can visulaize all the simulation process of the model.

Since container throughput is continually increasing, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations that support user needs require modeling tools that are both easy to use and sufficiently to reflect real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. This paper present the design procedure a simulator for port container terminal that was based on the object-oriented approach. The simulator in order to model and simulate the TC-based container terminals is developed.

최근 다양한 컨버전스 제품이 활발하게 개발되면서 사용자 유저 인터페이스의 연구가 매우 활발하게 이루지고 있으며 사용자 중심 연구에서 좀 더 구체적인 방향으로 사용자 경험 중심으로 사용자 인터페이스를 개발하고 있는 추세이다. 이러한 경향은 사용자의 중심개발 단계에서 다음 단계로 사용자의 감성을 잘 나타낼 수 있는 제품 개발을 초점을 맞추고자 하자 객관적 접근이 어려운 점이 있어 과거 사용자의 경험 자료를 기반 근거를 제시함으로써 판단 근거가 있는 사용자 유저 인터페이스 디자인 프로세스 및 설계 방향을 정립하게 되므로 좀 더 구체적이고 객관적 근거를 나타낼 수 있게 되었다. 이러한 관점에서 사용자의 경험을 나타내는 심리학적 설명 변수로서는 연령, 직업 등 은 제품 개발 시점에 사용자에 연구를 통해서 활발히 연구가 되어왔으며 해당 변수에 따른 제품들이 출시되고 있다. 반면에 문화적 차이로서 사용자의 경험을 구분하는 등의 심리적 차이에 대한 고려한 제품 개발은 아직 진척이 되고 있지 않다. 문화적 차이를 익히 알고 있지만 판단 근거가 연령이나 나이, 직업처럼 구분하기 어려운 점도 있다. 따라서 먼저 문화적 차이에 대한 이론적 배경 중 사용자 인터페이스 디자인에 관련하여 고려할 수 있는 사고유형에 따른 메뉴 정보 구조를 어떻게 디자인 할 것 인지에 대한 개념을 제시한다. 사고 유형 중 사물에 범주에 관한 사고 유형에 따른 구분으로 분석적 유형과 관계적 유형으로 구분하여 컨버전스 제품의 대표적인 디지털 TV의 메뉴 정보에 대한 유사성 및 관계성에 대한 평가를 실시하였다. 실시한 결과 분석적 유형 집단과 관계적 유형 집단의 결과가 차이를 나타내고 있고 이러한 차이를 고려한 메뉴 정보 디자인 컨셉을 이용하여 사용자 경험 중심 디자인 개발의 설명 변수로 사용하고자 한다.

This study aims to improve plans by analyzing spatial compositions of cohousing common houses, their role depending on the types of users and spaces, and satisfaction from the user-oriented design perspective. For this study, a basic concept was examined based on previous studies and literature reviews. So-Haeng-Ju(Happy House with Communication) Houses 1, 2, and 3 in Seongmisan Village was analyzed. As well, interviews with residents of these houses were conducted to analyze the role of user behavior in common house depending on the types of users and spaces. As a result, it was found that there were common characteristics of roles in an exchange with neighbors, cooperative child-care, and residents' meetings. The time and behavioral types were different depending on the living patterns, characteristics, and family members of residents. User satisfaction with the locations of community facilities including communal kitchen and communal living room, the composition of rooms, communication with residents, and the connection between communal living space and personal living space, was above the average. However, user satisfaction with storage facilities, or defect repair and facility maintenance was low. Most of cohousing common house users were satisfied with the use and size of spaces, and a sense of community, including communication with neighbors beyond the environment and Seongmisan Village. In conclusion, a realistic alternative is required for future cohousing by developing a system regarding human resources networks and cost bearing issues.
