This study was conducted to analyze the policy impacts of the '2014 Rural Field Forum'. From 2013, Ministry of Agriculture, Food and Rural Affairs implemented Rural Field Forum to push forward rural development of inhabitants' initiative. In this study, we have evaluated that Rural Field Forum has crucial impacts on residents' competence, region capability and driving force of project by targeting the 374 residents of 350 villages in 9 states who participated in 2014 Rural Field Forum. We also sought for the solution to institutional improvement. Futhermore we analyzed each of leader group and normal residents for departmentalization of policy effects. Taken together, the analysis reveals that: 1)Rural field forum is demonstrated to have a positive effect on the establishment and execution of village development plan and all of its necessary components. 2)Regarding the effect on the village capabilities, the understanding and recognition of village organization was shown to be improved. 3)About regional capabilities, the interest in village project was advanced. 4)In terms of the project execution, Rural field forum turned out to affect the village council processes positively. 5)lastly, between the leader and the residents, the difference effectiveness between them revealed, with the same directivity and considerably bigger effect felt by the leader than by the residents overall.

This study analyzed business ecosystems in 4 case regions(Yeongdong, Seocheon, Sunchang, and Hadong) that carry forward the regional $6^{th}$ industrialization. The analysis aimed to draw implications to build a healthy ecosystem for the sustainable development of the regional $6^{th}$ industrialization. As a result of the analysis, 4 districts show different characteristics for their growth stages, and these results provide implications for policy directions for the development of the regional industry. The following basic direction was set for the sustainable regional $6^{th}$ industrialization based on the healthy ecosystem. First, policy support should be differentiated by considering each region's growth stage. Second, to improve the regional innovation capacity, it is needed to lay the foundation continually and strengthen diverse support for it. Third, a stronger and efficient implementation system is necessary for the regional $6^{th}$ industrialization.

This paper presents the autonomous swimming technology developed for an Autonomous Underwater Vehicle (AUV) operating in the underwater jacket structure environment. To prevent the position divergence of the inertial navigation system constructed for the primary navigation solution for the vehicle, we've developed kinds of marker-recognition based underwater localization methods using both of optical and acoustic cameras. However, these two methods all require the artificial markers to be located near to the cameras mounted on the vehicle. Therefore, in the case of the vehicle far away from the structure where the markers are usually mounted on, we may need alternative position-aiding solution to guarantee the navigation accuracy. For this purpose, we develop a sonar image processing based underwater localization method using a Forward Looking Sonar (FLS) mounted in front of the vehicle. The primary purpose of this FLS is to detect the obstacles in front of the vehicle. According to the detected obstacle(s), we apply an Occupancy Grid Map (OGM) based path planning algorithm to derive an obstacle collision-free reference path. Experimental studies are carried out in the water tank and also in the Pohang Yeongilman port sea environment to demonstrate the effectiveness of the proposed autonomous swimming technology.

This paper analyzes the motion of a horseback riding robot which has two actuators and three joints. It is impossible to control the saddle to get to any position and orientation using the two motors because the robot has less degrees of freedom than the number of joints. Therefore it is required to know the possible location and orientation along with the velocity characteristics of each pose prior to motion planning. For this purpose, this paper analyzes the characteristics of the robot motion. The authors derive the forward and inverse kinematics of the robot motion and developed the trajectory editor for motion planning. Also, Jacobian of the robot is analyzed. It reveals that one of the actuator has little influence to the speed of the saddle motion while the other affects the speed of the saddle motion dominantly. The approach of the paper can be applied for the analysis of characteristics of a robot which has less number of actuators than that of joints.

Recently, as the concern over environmental problem has been serious all over the world, carbon has become a key issue to mitigate the problem. In the field of Architecture, various sustainable assessment systems and LCCO2 assessment strategies have been developed, guiding low carbon building while planning. However, assessment system for low carbon neighborhood, which can be more efficient strategy, is still in the stage of research. In this paper, as a research for low carbon assessment system and planning guideline for neighborhood, scope meeting domestic condition has been set and sustainable assessment system for neighborhood, which is similar to low carbon concept, have been compared. LEED-Neighborhood Development, BREEAM-Communities, CASBEE-Urban Development, and GBCC-Apartment Houses were used for comparison. As a result, it is found that those systems has many differences in judging system, aggregating method, scope of evaluation, and relations with a building assessment system. The concern about carbon is not insufficient yet. Finally, assessment system for low carbon neighborhood, which is not only for establishing the plan, but also for giving guideline at the very first state of the plan, should be developed as fast as passible. With the result of this paper, establishment of assessment criteria and the way to measure quantitative $CO_2$ should be studied forward.

This study aims at providing necessary resources in developing the sustainable project of the exchanges between cities and rural areas in Korea. And so I investigated and analyzed the model of the Setagaya Ward and the Gawaba Village in Japan, which has successively continued the exchanges between city and rural areas for thirty years, with the documentation, field work, interviews and field investigation. The two local autonomous entities have promoted the project of the exchanges between cities and rural areas by keeping in touch with a making the second home and linking agriculture with sightseeing. They passed an agreement of mutual help and established regulations to push forward the agreement in order to carry out the agreement. And they have operated a section which will do nothing but focus on this, established a management company which takes charge of the stronghold facilities of the exchange between city and rural areas, operated a caucus to examine the project steadily and to develop new programs, and made a publicity work continually for thirty years. In conclusion, I think we should promote the joint capital stronghold facilities of the exchange between city and rural areas which is based upon the agreements. And we should promote the infrastructure like a management company which takes charge of the facilities and build the proper foundation which can develop the various programs for the exchange between city and rural areas and operate them.

Foot bionic robot could be supported and towed through a series of discrete footholds and be adapted to rugged terrain through attitude adjustment. The vibration isolation of the robot could decouple the fuselage from foot-end trajectories, thus, the robot walked smoothly even if in a significant terrain. The gait programming and foot end trajectory algorithm were simulated. The quadruped robot of parallel five linkages with eight degrees of freedom were tested. The kinematics model of the robot was established by setting the corresponding coordinate system. The forward and inverse kinematics of both supporting and swinging legs were analyzed, and the angle function of single leg driving joint was obtained. The trajectory planning of both supporting and swinging phases was carried out, based on the control strategy of compound cycloid foot-end trajectory planning algorithm with zero impact. The single leg was simulated in Matlab with the established kinematic model. Finally, the walking mode of the robot was studied according to bionics principles. The diagonal gait was simulated and verified through the foot-end trajectory and the kinematics.

This paper proposes a novel fault-tolerant gait planning of a hexapod robot considering kinematic constraints. The failure concerned in this paper is a locked joint failure for which a joint in a leg cannot move and is locked in place. It is shown that the conventional fault-tolerant gait of a hexapod robot for forward walking on even terrain may be fallen into deadlock, depending on the configuration of the failed leg. For coping with such deadlock situation, a novel fault-tolerant gait planning is proposed. It can avoid deadlock by adjusting the position of the foot trajectory, and has the same leg sequence and stride length as those of the conventional fault-tolerant gait. To demonstrate the superiority of the proposed scheme, a case study is presented in which a hexapod robot, having walked over even terrain before a locked joint failure, could avoid deadlock and continue its walking by the proposed fault-tolerant gait planning.

The meaning and role of public space has existed based on the periodical situation like history. The more the time has passed, the faster the meaning of it has changed. We can see the differences of it from the one which used to be. This study is about Platoon Kunsthalle which is so-called the complex cultural space. The purpose of this study is to show how the user is related to the program for the planning of the public space. It is based on the procedure of the research with absorbing the place. The people who are using the space are absorbed for knowing the user's action. And then, the specific actions are written and the status of the using space is photographed. The research is based on asking and answering about that. The result of this study is as follows : The first is that young people between 20's and 30's are using a hall comparing with other age through daily using of space and features of users. Also, Using between 7p.m. and 9p.m., a dinnertime, takes the first place and using of meals and beverages is major at lunch due to restaurant and bar. User behavior of "sitting" is the biggest part and the hall is used for the public purpose connected with "talking". The second is that the daily hall space is classified with the spacial area indirectly based on the condition. Also, it depends on the time and the using. The third is that the unusual hall space is depended on the program which is the role of leading the extention of using the space. That is why the program is important because it is effected directly to the way of using the space and the place of the furniture. I am looking forward that this study is the basic data for the planning of the public space in the complicated culture.

The playgrounds installed in the city try a variety of changes in play equipment more than traditional playgrounds, these playgrounds with formal rides are still different from nature friendly playground. For this reason, when in 2014 the department of environment pushed forward 'Aitteulag' project constructing ecological playground, the department aimed to provide the natural ecological spaces that are insufficient in the city and act as play space for children, leisure and community space for residents. Therefore, after inspecting 10 ecological playgrounds in Europe and Japan, in this study we suggested the construction guidelines of ideal ecological playground by comparing and analyzing these cases. We checked the environment-friendliness of these playgrounds in the 2 fields (playground component, ecological program) based on the ecological playground guidelines presented by the ministry of environment. The playground components are classified as siting location, spatial configurations, natural elements, play area, amusement facilities, play materials, open spaces, additional facilities. The ecological programs are divided into habitat, species, natural material, five senses. The following is the summary of the results about the reflection of eco-friendly planning factors. In terms of "habitat": bush and shade wood were highest at 95%. In terms of "species": local indigene(100%) and habitat for insects(95%) were higher than others. In terms of "natural material": wood(61.1%) was the highest. In terms of "details of wood(61.1%)": wood fence (95%), exploring wood and using sticks(85%) were higher than others. In terms of "five senses": hearing (32.1%), tactile(26.4%), and visual(23.9%) were in order. Therefore, on the basis of these results, this study proposed the planning factors that should be considered and complemented more in the construction of domestic urban ecological playground in future.
