The purpose of this study is to investigate the overall recognition on attitudes of well-dying and evaluation the importance of planning factors of well-dying space in college students. This will serve as a basis to accumulate materials on the recognition of well-dying and well-dying spaces of various generations of South Korea. This study conducted a survey from October 4th to 8th, 2016 with 119 college students from U University and K University. As the contents of the survey, were comprised of general socio-demographic elements, subjective recognition and attitudes toward well-dying, and the importance of the planning factors of the physical, emotional, social and spiritual environments of the well-dying space. The main results are as follows. (1) The interest of university students on death education is high, and there was a preference for 'home' where they could be comfortable and be with loved ones as the space for dying. Also, in case of events of bereaving them after death, formal grieving ceremonies were undesired. The funeral was desired to be simple, serene, and not too sad. (2) In evaluation of the importance of physical, emotional, and spiritual environmental planning factors, physical environmental factors were considered to be the most important overall, and the recognition of importance of the planning factors of spiritual environment was low.

The storage style has changed because of diversity of family types, improvement of cost of living, and increase of leisure time. In spite of this change, storage space has still caused discomfort since it did not consider residents' convenience. Therefore, in this study, Brand Apartments were selected, furniture detail drawing was analyzed by plan of housing size and zone to calculate storage area and capacity, and finally needs of storage space were analyzed using survey. Satisfaction of storage space was generally low and $20{\sim}30%$ increase of storage space was demanded. The reasons why the storage space was not satisfied are followed. First, storage space was insufficient. Second, the inner structure of storage space was unified. According to change of life style, needs have changed. To satisfy these needs, the inner division of storage space is planned with considering various items. In addition, development of hardware, flexible division, and priority of storage space with considering user's convenience are needed.

Robot usually requires spline motion to move through multiple knots. In this paper, catmull-rom spline method is applied to the trajectory planning of industrial robot in task space. Centripetal catmull-rom is selected to avoid self-intersection and slow motion which can be occurred in uniform and chordal spline. The method to set two control points are proposed to satisfy velocity conditions of initial and final knots. To optimize robot motion, time scaling method is presented to minimize margin between real robot value and maximum value in velocity and acceleration. The simulation results show that the proposed methods are applied to trajectory planning and robot can follow the planned trajectory while robot motion does not exceed maximum value of velocity and acceleration.

The most important thing for navigation of a mobile robot is to find the most suitable path and avoid the obstacles in the static and dynamic environment. This paper presents a method to search the optimal path in start space extended to time domain with considering a velocity and a direction of moving obstacles. A modified version of $A^*$ algorithm has been applied for path planning in this work and proposed a method of path search to avoid a collision with moving obstacle in space-tim domain with a velocity and an orientation of obstacles. The velocity and the direction for moving obstacle are assumed as linear form. The simulation result shows that a mobile robot navigates safely among moving obstacles of constant linear velocity. This work can be applied for not only a moving robot but also a legged humanoid robot and all fields where the path planning is required.

We propose a planning algorithm to automatically generate a robust behavior plan (RBP) with which mobile robots can achieve their task goal from any initial states under dynamically changing environments. For this, task description space (TDS) is formulated, where a redundant task configuration space and simulation model of physical space are employed. Successful task episodes are collected, where $A^*$ algorithm is employed. Interesting TDS state vectors are extracted, where occurrence frequency is used. Clusters of TDS state vectors are found by using state transition tuples and features of state transition tuples. From these operations, characteristics of successfully performed tasks by a simulator are abstracted and generalized. Then, a robust behavior plan is constructed as an ordered tree structure, where nodes of the tree are represented by attentive TDS state vector of each cluster. The validity of our method is tested by real robot's experimentation for a box-pushing-into-a-goal task.

A design of Ice Cream Shop is an intended creation activity to increase the sales and profits by planning the space creativity and effectively. Accordingly, it should give the aesthetic and psychological satisfaction by making the space formative as a visual space expressed by a unique identity with a functional convenience. The design of Ice Cream Shop should reflect the changing demands and patterns of a consumption life as a result. Therefore a design plan is required to predict the living and culture. The design process can be divided into a basic planning, basic design and implementation design in large. The details are as follows. When a designer is assigned to the design from a client, he should start his work from surveying the site and arrangement, After arrangement, he sets up basic guidlines, which are called as a basic planning.

4D models help construction planners to develop and evaluate construction plans. However, current analyses using 4D models are mainly visual and limit the quantitative comparison of construction alternatives. This paper explores the usefulness of extracting quantitative information from 4D models to support time-space analyses. We use two 4D models of an industry test case to illustrate how to analyze 4D content quantitatively (i.e., work space areas and distances between concurrent activities). This paper shows how these two types of 4D content can be extracted from 4D models to support 4D-based-analysis and novel presentation of construction planning information. We suggest further research to formalize the content of 4D models to enable comparative quantitative analyses of construction planning alternatives. Formalized 4D content will enable the development of reasoning mechanisms that automate 4D-model-based analyses and provide the information content for informative presentations of construction planning information.

Taekwondo, Korean traditional martial art as one of the ten Korean cultural symbols, has acquired a reputation for introducing and globalizing Korean culture together with its standing as official Olympic Game in 2000, Sydney, Australia. Nevertheless the World Taekwondo Headquarters, Kukkiwon, which is an exclusive Taekwondo institution only accommodates for three thousand persons. Considering the worldwide reputation of Taekwondo, the scale of Kukkiwon leaves a big supply problem. This study therefore suggests the plan to design Taekwondo park that playa major role of Taekwondo development in the 21st century and represent the cultural heartland of Taekwondo. The study considers four points. The points are as follows: 1) Necessary programs drawn by analyzing and assessing Muju city as a site for Taekwondo park, then a survey conducted for potential visitors to a Taekwondo park. Under the theme of "A World Cultural Heritage Upon Our Own Lives", the park plan intends to become a shrine of Taekwondo as well as a big tourist attraction. 2) Programs are appropriate for the terms of the investment under the auspices of government, by considering potential visits and the site conditions. 3) The meaning of Taekwondo and its history should be reflected in the space distribution and facilities allotment. Three meaningful zones: symbolic zone, training zone and culture zone are considered in planning program and space distribution. 4) The plan also intends to harmonize with local development by groping Muju city's uplifting, not only designs a Taekwondo park.

The purpose of this study is to actualize the planning method of the shared community space (SCS). For this, it analyzed the residents' needs for the SCS and grasped the composition system of the needs and estimated the factors considered in the planning of the SCS. This study focused on seeking out the user-oriented design criteria for the planning of the SCS. The results of this study are as follows: First, as the results subdividing the residents' needs to understand the various requirements for the SCS, the composition system was classified into the fundamental SCS and the individual SCS. The fundamental SCS's to be considered as basic facilities in the planning of the multi-family housing complex, and the individual SCS to be more suited to a particular group. Second, regarding the investigation of detail guidelines in the SCS planning, it was found that there was a difference in the considered factors and the preferred locations according to the kinds of each SCS, the types of facilities, the main users of facilities, and the contents of activities available in the facilities.

The objective of this paper is to propose rural housing planning guidelines by conducting a survey on the needs of the elderly people engaged in farming activities and looking into complaints about their houses targeting 120 people from 50s to 70s. The method employed was a survey with questionnaires. The survey results showed the needs of the elderly for the rural housing are different from those of general retired elderly people because they still engage in farming activities even if they grow old. The needs are as follows. First, the respondents show high preference for the foyer storage to store equipments and goods related to agriculture. Second, the respondents have needs for enough kitchen area accommodating their house work and rural life. Lastly, the respondents highly prefer well planned storehouses in the exterior. In addition, they also want the storehouses directly connected with the house because this plan can save their workforce. They recognize storehouses are the most poorly planned space in the rural house because of the unsatisfactory space area and interior space planning. These needs should be reflected on the planning of rural housing for the elderly engaged in farming activities.
