In Korea, efforts have been made continuously to improve the environment of traditional markets concerning the issues of urban regeneration. In particular, many old cities and traditional markets face a lack of parking spaces. As a solution to this, attempts are being made to prepare underground parking spaces by designing urban planning facilities in three-dimensional ways and utilizing the upper part as a more meaningful space. This study is about the master plan to use the upper green area while creating an underground parking lot at 571 Sinmae-dong, Suseong-gu, Daegu. This green area was defined as a space with dual values, 'defensive green space' that needs to be ecologically protected, and 'active cultural space' where walking flows to the market and various events are concentrated. Three specific design strategies to balance these values were presented. First, to prevent indiscriminate occupation and damage by people and maintain a healthy green environment, securing the maximum amount of undivided green space in the site was suggested. Second, a space layout and a topography and planting patterns that can overcome the morphological characteristics of narrow and long-shaped sites enable the experience of abundant green spaces. Third, providing space to strengthen the connections with nearby urban facilities such as Sinmae Market and Gosan Library can also intensively accommodate cultural activities in various cities. This study has academic significance in providing implications for urban regeneration projects with similar contexts in the future.

Today, fishing villages are on the verge of extinction due to severe aging within the population and outward migration. Recent projects and studies targeting fishing villages viewed the fishing villages from an outsider-centered perspective, without a local-centered understanding of the village as a daily living space. Therefore, to understand the settlement environment of fishing villages, this study analyzed empirical data on the usage behavior of fishing village residents to gain insight into the characteristics of the outdoor space uses of residents in fishing villages. In this regard, a face-to-face survey was conducted among residents, and a village map drawn by the villagers showedthe spatial perception of the villagers. Empirical data on the behavior of fishing villagers using the village space was collected and analyzed through GPS. The study results suggested that residents of fishing villages tend to focus on productive activities, such as fishing, leading to a lack of awareness of other leisure activities and spaces. This monotonous pattern of space utilization within the village appears to stem from an absolute lack of available facilities within the target area. Therefore, in future village regeneration projects aimed at improving the quality of life for residents in fishing villages, it is essential to consider the residents' perception and utilization of space as a priority. The results of this study can be considered valuable foundational data for understanding the utilization of spaces within fishing villages and can be effectively utilized in planning initiatives to enhance quality of life.

Jansen mechanism is composed of mechanical walking linkages that are designed and optimized by Theo Jansen in 1990. Although he has made optimum values for linkage dimensions for Jansen Mechanism, there are still various applications for this mechanism and also various optimum values for each application. In this paper, Jansen Mechanism optimization has been processed for the Science Box. The Science Box has its own linkage dimensions and related components and makes space for optimization process. For the optimization 3 to 4 linkage were selected which had no similar ratios of linkages between other applied Jansen mechanisms and to reduce experiment numbers. Response Surface Method was used with Minitab 17 for optimization and m.sketch was used for experimentation. Intuitive method had to be used to find optimum values as with RSM optimum value could not be found. EDISON Designer was used to make final CAD model with optimum values and laser cutter was used to get appropriate acryl panels for legs.

This design proposal was presented to a design competition for renovation of the Pagoda Park, located in Chongro-2ga, Chongro-gu, Seoul, where the first ˝Manse˝ (hurrah) Movement fighting against Japanese colonization, broke out on March 1st, 1919. The park has been considered to be the first modern park in Korea also. The objectives for the design were to make a sacred place to commemorate the 3.1 ˝Manse˝ Movement, to preserve and symbolically memorialize historic remains of the old ˝Wongaksa˝ Temple, an to provide natural and rest areas for citizen. For the space composition, three axes symbolic of, ´freedom and independence´, ´mercy´, and ´nature´, were created. For the freedom and independence axis, exiting facilities, such as statures and monuments related to the 3.1 Movement, were relocated centering around the octagonal pavilion, which was the starting point for the movement, to give order of the site. For the ercy axis, symbols of traditional temple structures, such as, ´Iljugate´-´Pian bridge´-´Chongwang gate´-´Haetal gate´-Pagoda-Buddhist sanctum, were created to symbolize the temple remains and placeness. For the nature axis, tree groves, walking trails, and rest areas for citizen were provided around the site. As a whole the design provided structural orders from secular spaces outside to sacred spaces inside.

The purpose of the study was to identify the level of housing choice behavior by using the factors of residential satisfaction level, mobility motivation, and housing needs of potential purchasers in Bukgu New Housing Area, Ulsan. The survey used questionnaire from 326 households living in Bukgu and nearby area and analyzed using descriptive statistics. The research results showed low degree of residential satisfaction in storage space and neighborhood. The mobility motivations were improvement of physical environment improvement, education environment, walking road, view and lighting. The housing needs for indoor spaces showed to want more functional arrangement than the room size. The housing needs for outdoor spaces showed to want neighborhood environment in connection with the education or hospital facilities, the welfare facilities for pre-kindergarten children and elders and the leisure facilities. And the housing needs for facilities were floor furnishing for health, crime prevention system for safety needs, housekeeping appliance against environmental pollution, additional function for energy saving. The housing needs for common spaces showed that the residents preferred playing facilities by age group, exercise facilities, the community hall and the rest room which can do games or meetings.

In recently, a growing concern for the health of urban residents increased interests in a variety of outdoor activities simply be done in terms of cost and time. They are specially interested in low-impact and safe exercises around residential or working area. Walking is the one of easily doing exercise in daytime or nighttime near residential area. The sidewalks of boulevard near the residential area is the best place for exercise because of easy access and the green space with roadside trees. However, if the nighttime is not guaranteed the proper lighting condition, the possibility of exposure to crime and the threat to pedestrian safety can be increased. Because roadside trees are one of the potential obstacle for lighting condition, supplementary lightings are important to mitigate interruption for safety. To meet such a need, the purpose of this study is to propose a simulation approach which improves lighting condition on sidewalks of boulevard with variety of roadside trees. To do so, the simulation approach is applied for analyzing the interrupted condition by classified five standard types of roadside trees considering the growth of them and finding optimal layout of supplementary luminaires by lighting types. The results of this approach shows that it is useful for assessing the safety of pedestrian in nighttime.

The purpose of this survey study is to analyse the playground dimension of elementary school. To complete this mission, it is necessary to drive out elementary school have a lower dimension standard of playground through literal survey. Then, questionnaire and observation survey have been performed to teachers majored in physical education and these are focused on playground dimensions. The field survey study will provide the basic data for calculating proper playground dimensions and design source for planning space program of the school. The result of this survey study are as follows ; First, The Area of 'Gyo-ghi' is decreasing, and the land area of being used for 'Gyo-sa' is increasing. So the area of playground is decreasing. Second, The respondents require a playground size enough to contain 100m running track for testing the physical ability of students. But it is not possible to do so in current domestic condition, it is necessary to revise of the standard of physical test or enact a new one. Third, to solve the problems deviating from the playground size, the respondent suggests that set up a new gym or variable-size playgrounds rather than a large one Fourth, because playground has so much functions as rest, playing, walking and jogging etc besides physical education, it is necessary to consider the spaces for rest and play, when plan a tower-type school or small school.

Gait analysis is an effective clinical tool across a wide range of applications. Recently, inertial measurement units have been extensively utilized for gait analysis. Effective gait analyses require good estimates of heel-strike and toe-off events. Previous studies have focused on the effective device position and type of triaxis direction to detect gait events. This study proposes an effective heel-strike and toe-off detection algorithm using a smart insole with inertial measurement units. This method detects heel-strike and toe-off events through a time-frequency analysis by limiting the range. To assess its performance, gait data for seven healthy male subjects during walking and running were acquired. The proposed heel-strike and toe-off detection algorithm yielded the largest error of 0.03 seconds for running toe-off events, and an average of 0-0.01 seconds for other gait tests. Novel gait analyses could be conducted without suffering from space limitations because gait parameters such as the cadence, stance phase time, swing phase time, single-support time, and double-support time can all be estimated using the proposed heel-strike and toe-off detection algorithm.

Recently, many patients in a hospital are threatened life by fire disaster. Because many patients like vulnerable people have more evacuation problem than ordinary person. So a patient who can escape by oneself with walking assistance device like crutches or wheelchair and another patient who can't escape by oneself are should be supported safety technologies and service. Earlier research of 'hospital evacuation' led by actual experiments or computer evacuation simulation. Actual experiment is effective to gain credibility of result but it is difficult for patients to experiment repeatedly and it requires consideration for spatial problem and economic problems. Although computer evacuation simulation have been used to solve these problems, almost have concluded only results based on velocity without evacuation device. In this study, evacuation results with support device application or not are analysed used by computer evacuation simulation based on MAS(Multi Agent System). As a result, it is drawn through proof of efficiency of evacuation device in the vertical space like stairs that can improve the evacuation plan for vulnerable people in the hospital.

This study aimed at creation of bench design to be placed in the public spaces for the citizen who live in Jungnang-Gu. In Jungnang-Gu surrounded by the excellent natural environment like Jungnang-stream, Mangwoo Mt., Bongwha Mt. and Youngma Mt., there are many public places where a citizen can take a rest. Among the public facilities being in such public places however, the benches especially were installed so unplanned and disordered, even that they look unbalanced with the natural environment, though they need to play a meaningful role in park and walking paths. Hereupon this study intends to investigate the geographical environment in Jungnang-Gu and furthermore to develop the bench-design on the basis of the investigation. The concept of design lies in modern style of a bench matched up with the nature well and also taking the functional aspect for rest, in consideration of the public places utilized by the abundant natural greens. The environment-friendly timber, marble and metal were used here and the design with and without the back of a bench & the dimension for Korean people's figure were considered.
