The objective of this study is to survey and analyze convenience of the disabled people to use the facilities in accommodations. The data used in this research has been obtained in the southern sea of Korea. According to the survey, it was very difficult for the disabled people with a wheel chair to access to the room because of the staircase, doorsill and the narrowed passage. Also, there was no the grab bar, braille blocks and exclusive elevators for the disabled. Moreover, it was not easy for them to access to the bedroom since there was a doorsill and a serious height difference between the lobby and the bedroom. It was shown that the disabled People also have a difficulty in using the toilet and the bathroom, because the width of door and floor height was not suitable for the design criteria. In the toilet, there was no handle on a chamber pot for the disabled people to hold, and the space was not enough for them to access to the pot and turn with a wheel chair.

A submarine good military weapon because of its confidentiality and intimidating power. Therefore, training warfighters how to maneuver submarine is very important. Because submarine is very expensive and has regional and temporal limitations, M&S(Modeling and Simulation) can be a good alternative. However, as the existing M&S systems of submarine generally use expensive commercial software and dedicated hardware, which cause the warfighters to take troubles to visit the secured places, and then to train themselves during limited time slots. Also, many M&S systems have only one-channel display system which reduces the sense of immersiveness. Another problem is that many heterogeneous simulators can hardly be used as an integrated system. To solve these problems, X3D, a platform-independent and open standard graphic file format, is used with the general-purpose PCs. To increase immersiveness, multi-channel display system and a motion chair are used. Finally, HLA/RTI is used to integrate individual components of the simulator. All of these are verified through experiments.

The global movie industry is continuing rapid growth through application of the latest technology. 3D movies are being produced and shown for a more effective viewing experience. Special chairs for audiences are being experimentally manufactured and installed for the greatest viewing effect. This special chair has a structure that applies vibrating stimuli to specific parts of the body by attaching vibration transducers to theater chairs and synchronizing it with each scene of the movie. In a previous study, it has been confirmed that we can analyze the vibration transfer characteristics of sponge seats through the application of an experimental modal analysis method and obtain design variables easily. In this paper, we examine the major design parameters needed in the development of a foaming sponge seat in which auxiliary springs are inserted to improve the vibration transfer effect of a chair seat. Through analyzing several prototypes by applying experimentation as well as the experimental modal analysis method, it was confirmed that the effect of vibration transfer can be improved through the use of an auxiliary member.

The volume changes associated with moisture or suction variation in expansive soils are of geotechnical and geoenvironmental design concern. These changes can impact the performance of infrastructure projects and lightweight structures. Assessment of unsaturated function for these materials leads to better interpretation and understanding, as well as providing accurate and economic design. In this study, expansive soils from different regions of Saudi Arabia were studied for their basic properties including gradation, plasticity and shrinkage, swelling, and consolidation characteristics. The unsaturated soil functions of saturated water content, air-entry values, and residual states were determined by conducting the tests for the entire soil water characteristic curves (SWCC) using different techniques. An attempt has been made to provide a prediction model for unsaturated properties based on the basic properties of these soils. Once the profile of SWCC has been predicted the time and cost for many tests can be saved. These predictions can be utilized in practice for the application of unsaturated soil mechanics on geotechnical and geoenvironmental projects.

Purpose: The purpose of this paper is to provide logical basis on enlargement of toilet floor space for the disabled by "ACT ON GUARANTEE OF PROMOTION OF CONVENIENCE OF PERSONS WITH DISABILITIES, THE AGED, PREGNANT WOMEN. ETC" Revised Enforcement regulation [Asterisk 1] (2018.2.10.) and to help with making plans, designs and establishing policies by conducting experimental study with the enhanced floor area regulations. Methods: We conduct Experimental study, field work and interview for this paper. In experimental study, verification of the effective floor area was proceeded by measuring activity space for people in manual wheelchair, electric wheel chair and electric scooter and also reviewed useable area with the space expanded 0.2m both width and depth. In filed work, conducted an observation what other things (ex. sanitary equipment, hand rail and so on) can also affect the active space as well as effective floor space. In the interview, other problems and requirements that were not revealed were experimental study and observation of field work. Results : it's expected to provide better access to toilets for the disabled with the law revision of effective floor area. But, with the usage increasement of enlarged wheel chair and electric wheel chair, expanding side areas of toilet is also highly likely to be required going forward. Implications : Additional research is required on locations of exists and internal arrangement that effect the usage of toilet. It should be led to Universal design by making additional investigation and verification of the users patterns.

Furniture in the modern living environment, inclusive the importance of its practical value, is a plastic element of indoor space, and its artistic value also holds an important position. Moreover, emotional design based on the emotional engineering in a structural change of modern society such as urbanization, small family, aging society is proposed as an important keyword in the modern design. Namely, furniture as an component of modern residential space has been advanced as a human-oriented environmental element considering people's emotional and mental value to the functional satisfaction and artistic and emotional satisfaction. Furniture is a living tool that is much contacted to people, which affects highly on people's body and mind. This means that people's volition action can be naturally induced by furniture design, and that furniture can display a role as an active tool of means to make people's interpersonal communication and interchange. Namely, I think furniture design of emotional interchange that understands furniture user's pattern behavior and pattern, and observes furniture form and structure and functionality on users' relationship affecting on people's emotional stability and interpersonal interchange of emotion, as an indispensable element necessary for producing more human and prosperous environment of life.

Objective: The purpose of this study is to evaluate integral seat desk used in universities through comparison of real dimension values of the desk with KS/ISO standard and questionnaire survey. Background: School furniture that helps students sit comfortably for longer periods of time and allows for better concentration on learning is important. However, seat and desk have been generally designed based on the industry practice rather than user's anthropometry, and seats and desks used in universities of Korea have not been ergonomically evaluated. Method: Real 13 dimensions of the desk used in K University were measured using tape measure and inclinometer, and the dimension values were compared to the KS standard of desk and chair for lecture room (KS G 4210) and ergonomic design principles found in relevant references. Subjective appropriacies and preference for the desk were investigated based on questionnaire survey, in which 121 (male: 91, female: 30) college students participated. Results: Several dimensions for the desk and chair investigated except desk depth and width, leg room width, seat width have not met the KS standard, but all dimensions satisfied ergonomic design principles available in references. The questionnaire survey revealed that appropriacies for desk surface size, seat pan depth, seat pan cushion and backrest curvature were under middle point of 3.0, and that those for the other dimensions showed higher scores exceeding 3.0. Conclusion: The integral seat desk widely used in universities showed some design problems in terms of standards of KS G 2010 and KS G 4210, and ergonomic design principles. Compared to the general desk with separated desk and seat, subjective preference on the integral seat desk was low. Application: This would be used as a valuable guideline when designing or choosing new integral seat desk with high satisfaction of students.

Laying stress on the upper classes of Western Europe until from the seventeenth to the eighteenth century, the chinese mode in the fields of architecture, interior design and fashion was widely liked. It is called as ‘chinoiserie’into the French language. The chinese design with its quantity and ornamentation exerted an influence upon‘Rococo’in France and upon ‘Chippendale’ in England. The chinese mode that was made best use of the furniture design is the one of Ming dynasty. This was developed in relation to the interior design of ‘Siheyuan’ that is the architectural mode in those days. The furnitures at the times of Ming dynasty was raised to the position of the golden era in the history of chinese furnitures. The furniture has the technique laying stress on symmetrical proportion, simplicity. This technique showed as the formative modeling. also on the part of decoration ornamental designs showing the china ideology of Taoism, Buddhism and Confucianism it was used. In this formative modeling the ideological background of those days forms the groundwork. The combination of reason and sentiment and of heart and mind emphasizes that our emotion should be in control by the ration and our emotion and ration should be harmonized.
