Although the improvements in the health sanitary facilities of the elementary school were made by the implementation of the 7th curriculum, color design and concept of toilets used by lower classes students were shown to be still insufficient and so, it is also necessary to have color planning for toilets considering users' preferences. This study is targeting lower classes children of elementary schools under Seoul Gangseo Office of Education. The purpose of this study is to propose a toilet color design direction preferred by children as users. Therefore, the toilets of elementary school were investigated and at the same time, juvenile pictures were analyzed. The results of this study are that the color space used in the current design, the following gives a substantial psychological and emotional impact for many elementary school children in the developmental stages of children leads to an interesting use of color. Therefore, this study propose to improve the toilet to a more familiar environment with high accessibility considering the development of the child when using color in design space through color preference.

The purpose of this study was to investigate the related factor for the prevalence of musculoskeletal symptoms among 212 sewing worker. The survey was performed with self-administered questionnaire for the risk factors related to musculoskeletal disorders(MSDs) from August 5 to 7 in 2005. The prevalence of musculoskeletal symptoms were 75.8% and the those of the local symptoms were 71.7 % for shoulder, 60.4 % for neck, 35.8 % for arm and 50.9 % for wrist. The risk factors related the self-reported MSDs had not shown in general characteristics. But, there was a significant difference between daily working hour and wrist, working speed and neck, the degree of satisfaction and wrist for work related factor. Also, it was shown the significant difference between chair height and neck, the height of sewing machine and wrist among the space below work station, neck, waist for the prevalence of musculoskeletal symptoms. The significant correlation was shown for daily working hour and wrist, working speed and arm, work load and shoulder and the degree of satisfaction and arm for work related subjective symptom. Considering above results, it is suggested the ergonomic design be provided to working hour, the height of chair and work station as well as daily working hour even there is a significant difference for the prevalence of symptoms in each body part for sewing workers.

Elementary school's physical environment is critical to lower grade students. Among the many physical conditions, Toilet, which belongs to health and sanitation category is very important to those who start school for the first time. The purpose of this study is for suggesting the guidelines of toilet design reflecting psychological and behavioral aspects of lower grade students. The research was executed as follows. Firstly, focused survey groups were carefully chosen. Five elementary schools were selected, being all open after 2005 under Seoul Gangseo District Office of Education. Secondly, field study was executed to find out toilet usage, during the period between April to June 2012, by visiting schools to see basic facilities, taking pictures and making actual measurement in each toilets. The architectural analysis was focused on location, moving line, actual size and space zoning, while the interior analysis being on finishing materials and the design of sanitary equipments. And the design elements such as color, lighting fixture, art works or signage were analysed, too. Finally, questionnaire survey was done to find out preferences of lower grade students. As a result, the guidelines of toilet design can be divided into two main parts, Physical and Psychological. For the Physical part, it is necessary for related facilities to be concentrated in order to give easy access. In addition, good ventilation, better lighting and to install sanitary equipments ergonomically are required. Furthermore, safe and clean maintenance should be considered. Psychologically, the design should be directed for making lower grade students come to toilets with comfort and more pleasantly.

While the ideal universality of the modern period has achieved outstanding results in terms of establishing sanitary cities in contemporary urban environments, it has caused the decline of the genius loci. This study raises the question of the lost sense of place and proposes a solution, 'The Human-Environmental Ecological City'. The Human-Environmental Ecological City, called 'Ecoumenal City', does not provide a fake idealism with the conclusion of modernity of non-place or sense of place without modernity. It is both cosmological and geogenic, and the technology of the time is projected onto it human-environmentally. It does not pursue any more a urban planning as the overall work of an individual, but it aims at a balance rediscovered through the individual spontaneousness.

Concerns regarding work and food safety in foodservice operations are growing. The purpose of the study is to suggest guidelines for designing foodservice facilities, including school foodservices and Korean restaurants. A case of a franchise restaurant specializing in a Korean food item, Seolleongtang, was used to explain the facility design. The contents of the manual included ways to determine space allocation, calculate the application of utilities and the diameters of supply utility pipelines, and suggestions on how to decide on air conditioning equipment. The standards of the American Gas Association and the Japan Foodservice Equipment Association (JFEA) were applied to design the restaurant space. The JFEA standards and knowledge based on experience and statistics were applied to calculate the usage of utilities like fuel and water. The standards of JFEA and the Society of Heating, Air-Conditioning, and Sanitary Engineers of Japan were applied to calculate the diameters of the water supply and drainage pipelines. For the setting of the heating, ventilation, and air conditioning systems, three ways to carry out the calculation of effective ventilation were explained, as well as options to dicide the standard parameters of the duct and ventilation fans. This manual can contribute to the design of effective and efficient foodservice facilities and help secure the work safety of foodservice employees thereby ensuring food safety.

Purpose: The main purpose of this study is to develop an evaluation system using the weighted-values of various users and experts for the public space to apply Universal Design, and additionally to find out the commonalities and differences by comparing the importance of evaluation indicators between users and expert groups. Method: A one-sample t-test was conducted to verify that the components of the public space to universal design application are suitable as evaluation indicators, and AHP(analytic hierarchy process) was performed to derive weight-values for the evaluation system. Results: The importance-values for the total 23 facilities to be used as evaluation indicators were derived by multiplying the weighted-values of each sector, domain, and facility by the disabled, non-disabled, and experts. To summarize the results of overall importance-values derived from the AHP, The disabled showed high-rank weighted-values in facilities of building sector > park & recreation sector > cross domain and low-rank weighted-values for sidewalk and roadway domain. The non-disabled showed high-rank weighted-values in facilities of park & recreation sector > roadway domain > building sector > cross domain and low-rank weighted-values for sidewalk domain. Experts mainly showed high-rank weighted-values in the cross domain and in facilities related to entry and movement to the target space in all sectors and domains. However, it showed moderate importance-values in the sanitary space. The disabled who are restricted to movement have a high demand for universal design in buildings consisting of vertical moving line, and non-disabled people who are not limited to physical movement have a high demand for universal design in parks and recreation sector for increased leisure time. It means that experts are important to recognize the principles of making space because they value cross domain and the key spaces and facilities for suitable the purpose of use. In addition, it can be inferred that non-disabled people have a higher demand for safety than disabled people due to their high importance in roadway domain and facilities of safety and disaster prevention. Implications: The significance of this study is the establishment of a quantitative universal design evaluation system for public spaces considering the different perspectives of the disabled and the non-disabled.

A study on child care centers has been developed with a focus on normal children. Also the child care centers which take care of children with disability are rare. In Seoul, Korea, only 2% of children with disability are taken care of in child care centers. And even the disabled children at the child care centers are mostly mentally or emotionally disabled because the building, programs and services of the centers are restrictive to the children with severe physical disabilities. In Korea, it is not yet an obligation for child care centers to adopt Disability Accessibility Guidelines to make facilities accessible by the disabled. Also, Korea does not have specific design guidelines or legal standards. This study aims to review the legal standards and design guidelines which are applicable to child care centers for children with disability through a reference review. Japanese legal standards and references were collected and analyzed. As a result, we categorized the guidelines according to contents such as locations, areas, space organizations, nursing spaces, sanitary spaces, and doors and corridors. The goal of this study is to provide the basic information to develop domestic design guidelines to ensure that the child care centers are welcoming and usable for everyone possible.
