소셜 미디어 환경의 도래로 다수의 사용자들이 자신만의 콘텐츠를 생성하고 공유하는 일이 많아졌다. 특히 여행이 대중적 취미로 자리잡으면서 여행에 관련된 콘텐츠도 늘어나고 있다. 하지만 여행 콘텐츠를 위한 효율적 시스템은 많지 않으며 기능이 미약하거나 복잡한 인터페이스로 인해 사용률이 낮은 편이다. 따라서 본 논문에서는 이를 보완하기 위하여 스케치 기반의 비주얼 북마킹을 이용한 여행 플래너 시스템을 제안한다. 사용자가 스케치와 제스처를 사용한 비주얼 북마킹을 이용하여 여행지에 관련한 자료를 간단한 태그를 붙여 북마크를 생성하면 지도 위에 자동으로 북마크가 생성되어 사용자는 북마크의 위치를 보고 루트를 정할 수 있다. 이를 이용하여 사용자는 여행의 목적을 잘 표현할 수 있는 여행 일정을 쉽고 다양하게 작성할 수 있다. 또한 사용자가 자신만의 여행 후기를 정리하여 다른 사람들과 쉽게 공유할 수 있는 도구로 활용될 수 있다.

여행에서 스마트 폰을 활용하는 경우가 일반화되어 있지만, 대부분의 여행 애플리케이션들은 여행을 테마별 혹은 특정 지역 중심으로 여행객들의 관심 여행지를 추천만 해주는 형태가 대부분이다. 그러나 대부분의 여행객들은 여행 일정을 만드는데 많은 시간과 노력을 필요로 한다. 따라서 본 연구는 사용자가 원하는 코스를 계획하여 좋은 관광명소, 숙박시설을 최소 경비와 최소 시간으로 여행을 할 수 있게 서비스를 제공한다.

전통적 계획방식은 결정적 효과를 간진 동작들로 이루어진 도메인을 다룬다. 따라서 전통적 계획기는 동작이 환경을 어떻게 변화시킬지 명확하게 예측할 수 있다. 그러나, 많은 실제 응용들에서는 불완전한 정보와 비-결정적 효과를 처리할 수 있는 계획방식을 요구한다. 확률적 계획방식은 확률적 효과를 가진 동작들을 포함함으로써 이러한 요구를 만족한다. 확률적 계획기는 일반적으로 목표상태에 도달하기 위한 하나의 행동정책을 찾아내며, 이는 (상태, 동작)쌍들의 집합으로 표현된다. 그러나 확률적 효과를 포함시킴으로써 계획기들의 복잡도가 이전보다 증가되었다. 본 논문에서는 효율적인 확률적 계획기의 설계와 구현에 대해 설명한다. 이 계획기는 표준 PPDDL 언어로 표현된 도메인 묘사를 입력으로 받아들이며, 실시간 동적 프로그래밍 알고리즘을 채용하고, 간략화한 문제로부터 추출된 휴리스틱 지식을 이용한다. 생성된 상태들과 행동정책을 효율적으로 저장하기 위해, 이 확률적 계획기는 해쉬테이블을 이용한다.

The users' needs are expanded because of developing of educational robot market. However, the technology development doesn't fully adopt customer needs. In general, the most products are followed not user needs but technology trajectory. In this paper, we try to define the educational robot functions from analyzing usage propensity and customer needs with Kano model. According to results, there are key functions based on customer needs such as remote student control, Internet search, educational contents search and study planner. If the four key functions are offered, user's positive attitude to robot will be increased.

With the recently increasing need for more theoretical approach on family resources aiming healthy family in the society, this study is to emphasize how important time, a personal resource, means for a healthy family and to seek how effectively time can be managed by referring to some documents. The followings are to be suggested in order for anyone to be able to apply by oneself to achieve a healthy family. First, time should be planned minute by minute. Second, prioritization should be done. Third, deadline should be made. Fourth, day planner and keeping a journal on it are recommended.

This study aims at clarifying the planning methods and historical significance of Park Byung-Joo's New Seoul Blank Plan(1966) in the context of South Korea's Urban Design during the 1960-1970s. In addition, it also tries to reveal how the planner's ideas were transformed into realized urban projects in Korea. By the comparison of the New Seoul Blank Plan and these projects, we can come to understand how the new concepts of urban planning such as CIAM's planning principles, Neighborhood Unit Theory, New Town plan and green belt concept were adapted to Korean society in the 1960s and 1970s.

We propose a task and motion planning algorithm for clearing obstacles and wiping surfaces, which is essential for surface disinfection during the pathogen disinfection process. The proposed task and motion planning algorithm determines task parameters such as grasping pose and placement location during the planning process without using pre-specified or discretized values. Furthermore, to quickly inspect many unit motions, we propose a motion feasibility prediction algorithm consisting of collision checking and an SVM model for inverse mechanics and self-collision prediction. Planning time analysis shows that the feasibility prediction algorithm can significantly increase the planning speed and success rates in situations with multiple obstacles. Finally, we implemented a hierarchical control scheme to enable wiping motion while following a planner-generated joint trajectory. We verified our planning and control framework by conducted an obstacle-clearing and surface wiping experiment in a simulated disinfection environment.

It is commonly recognized to need performance management for successful construction project. PPC measurement of Last Planner System is one of construction project measurement method. PPC measurement is quantitatively assessment to go through construction, and that is not completely to be trusted when compare a project with another or an individual case work with another in same project. According to, purpose of this study is comparison indicator establishment that compare project with another or an individual case work with another it is not use PPC measurement for quantitatively assessment to go through construction. The procedure of this study is derive of the point at issue of existing PPC measurement for a aim PPC measurement in this study expenditure and select weight about that and it is applied to actually construction.

This paper presents a GA-based optimal algorithm for a resource leveling model that levels the resources of a set of non-critical activities experiencing conflicts simultaneously up to an assumed level of resource rates specified by the planner using a pair-wise comparison of the activities being considered. A parameter called the future float is adopted and applied as an indicator for assigning leveling priorities to the sets of activities experiencing conflicts. A construction project network example was worked out to demonstrate the performance of the proposed method. The histogram obtained using the algorithm proposed was shown to be the same as, or very close to that produced by the existing resource leveling method based on the least total float rule, which shifts non-critical activities individually.

In this paper, the automated initial process planning for 3-axis NC machining of sculptured surfaces is persented. The solution algorithms determining three process planning functions, i.e. machining feasibility, setup orientation and feasible machine selection are developed. The machining feasibility is determined by means of BSM(Binary Spherical Map) which derives its solution quickly in algebraic form, and the setup orientation is determined so that the cutting force is minimized. Finally, the feasible machine is determined by computing the minimum motion ranges of each control axisl. The developed algorithms are tested by numerical simulations, convincing they can by readily implemented on the CAD/CAM system as a process planner.
