Recently, through the services that use drones at fire sites to deliver on-site and road conditions into the situation room and life-saving activities or the deliveries of first aid outfits at the accident scenes that are inaccessible to humans, there are more and more cases of dealing with emergency situations. Therefore, by studying the service design using drones in the initial stage of response to fires in dense residential areas, this study was intended to reify the service design area of the response stage, including the dispatch of fire sites and the fire suppression. To do this, through literature researches, research directions were explored by examining the concept and process review of service design, and by analyzing the application cases using service design. In order examine the validity of this study, a one-on-one interview was conducted to identify the use and problems of drones among incumbent firefighters, and identified the applicability of drones to fire sites by targeting drone experts. Field research was conducted to identify the location and distance of road conditions, site conditions, and 119 safety centers, by making Yongsan-gu, the most vulnerable area to fire in Seoul, as a research sample. And, among the methodologies of service design, Persona and Customer Journey Map were prepared and Insight was derived, by using virtual scenarios for the experience values and behavior analyses of the interested parties. Through these processes, this researcher intended to present the fire-response service design and help establish the direction of service design in the initial stages of fire in Korea.

Ludo-narrative dissonance is a prevalent problem among open-world genre video games. However, Ghost of Tsushima (2020) alleviates this issue by designing its characters and narrative structure influenced by Akira Kurosawa's samurai films. The game's protagonist represents "Bushido," a samurai code, and the structure exudes similarity to Joseph Campbell's "Hero's Journey," which heavily influenced Kurosawa's films. The developers also designed the gameplay mechanics such as level-up system, map design, and side quests based on these narrative traits, ultimately making the goal of the narrative and the gameplay mechanics cohesive.

서비스화(servitization)와 공유경제 패러다임이 확산되면서 서비스 산업에서도 IT기술을 융합시킨 다양한 형태의 새로운 비즈니스가 성공적으로 정착되고 있다. 특히 대중교통 서비스 산업에서 우버(Uber) 택시는 IT기술과 공유경제 개념을 절묘하게 접목시킨 새로운 차원의 성공적인 공유택시 비즈니스 모델로 자리매김하였고, IT기술을 적용한 교통예약 소프트웨어는 공유택시의 차별적 경쟁우위를 확보하기 위한 중요한 수단이 되고 있다. 공유택시 예약 프로그램은 택시이용자에게 신속하고 편리함을 제공할 뿐만 아니라 에너지 절약, 교통체증으로 인한 스트레스 완화 등의 많은 사회적 혜택과 이익을 제공하고 있기 때문에, 여러 분야에서 다양한 연구가 진행되고 있다. 최근 중국에서는 보다 진보된 공유택시 예약 프로그램이 공유택시에 접목되면서 공유택시 이용객이 급히 증가하고 있으며, 이와 함께 공유택시 차별화에 핵심적인 역할을 하는 소프트웨어 시장의 경쟁도 가속화 되고 있다. 그러나, 이용객을 대상으로 강력범죄 발생빈도 증가와 이로 인한 부정적인 여론의 급속한 확산은 공유택시 산업발전에 심각한 방해요인이 되고 있지만, 근본적인 해결방법에 관한 연구는 미비한 실정이다. 따라서 본 연구는 공유택시 예약 프로그램에 이용객의 안전을 위한 컨텐츠 개발과 적용을 통해 공유택시 이용객의 불안해소와 공유택시 산업 발전에 기여할 수 있는 방법을 제안하고자 하였다. 연구방법은 중국현지의 공유택시 이용객을 대상으로 실증연구를 진행할 계획이며, 고객여정맵(CJM)과 Kano 분석을 통해 결과와 시사점을 도출할 계획이다.

In the stealth game design, level designers are to develop many interesting game environments with a variety of difficulties. J. Tremblay and his co-authors developed a Unity-based level design tool to help and automate this process. Given a map, if the designer inputs several game factors such as guard paths and velocities, their vision, and the player's initial and goal positions, then the tool visualizes simulation results including (clustered) possible paths a player could take to avoid detection. Thus with the help of this tool, the designer can ensure in realtime if the current game factors result in the intended difficulties and players paths, and if necessary adjust the factors. In this note, we present our improvement on this tool in two aspects. First, we integrate a function that if the designer inputs some vertices in the map, then the tool systematically generates and suggests interesting guard paths containing these vertices of various difficulties, which enhances its convenience and usefulness as a tool. Second, we replace the collision-detection function and the RRT-based (player) path generation function, by our new collision-check function and a Delaunay roadmap-based path generation function, which remarkably improves the simulation process in time-efficiency.

The purpose of this study is to develop the usability evaluation contents based on the needs of different stakeholder's related to the usability of the product, and to derive the design direction and apply it as the evaluation standard by applying the product design based on the results. I created a stakeholder map for a fire detector product and identified stakeholders related to usability. Based on 3 factors(Physical, cognitive, emotional) of the usability evaluation, I conducted survey on the building users and the building managers who have different requirements. There are 12 directions (ease of installation, durability, maintainability, additional functionality, effectiveness, attractiveness, visibility, consistency of information, environmental harmony, consistency, Image suitability, reliability). Through weighted analysis of three usability evaluation factors, I found factors were ranked in the same order of importance, but they were different in importance figure. Based on the results of the survey, overall product usability aspects were improved but effectiveness and environmental coordination aspects needed to be improved.

Hierarchy which is often named as the tree-structure is used to reduce complexity and show primitive structures of complicated information. This paper aims at explaining information-visualization methods using hierarchies in multimedia domains and prospecting the possible applications by examining how they affect the user's tasks involved in information-seeking activities. As a result, four types of information visualization methods named Treemap, Hyperbolic, Cone Tree and DOI Tree employed in multimedia domain, are presented and pros and cons of each method are explained in this paper. Another important part is defining the core tasks and other related-tasks in information-seeking activities, such as, overview, zoom, filter, details-on-demand, relate, history, and extract. Followings are major findings. Treemap uses 'overview' as the core task, which makes user to gain a overall meaning of the whole information cluster. Hyperbolic and DOI Tree apply 'Boom' task through the function of focus+context or by the function of meaningful scaling to magnify or downsize each node. Cone Tree, also, makes the information organizer to classify the patterns of information acquired in the process of users' information-seeking activities by using 'extract' task. Through this study, it is finally found out that the information-visualization methods using hierarchies in multimedia domains should incorporate the wide variety of functional needs related to users' information-seeking behaviors beyond the visual representation of information.
