Ergonomic ship design aims to improve the safety and convenience of crew and passenger. Recently, ergonomic design is a key issue in the warship design, as a basis of analysing and evaluating ergonomic design and evaluation methods for warship, existing military design guidelines and navy criteria in the fields of ergonomics were surveyed. Also, the methodology including ergonomic human model was introduced. Finally, it is shown that the ergonomics evaluation of a design at the early stage of warship design can be performed using commercial ergonomics evaluation model such as Delmia's ERGO.

This study is to suggest a strategy and trend of products development by major construction companies to form a trend and to set the trend in housing market through investigation about brand image campaign for TV ad, individual design items, result of products development and special plans. It is the strategy for products development of construction companies surveyed to be divided into five kinds. First, the change from in the unit to outside. Second, centralization of design powers about products development through submit and the wining of a prize in the domestic & foreign design fair to publicize a excellent quality in a roundabout way. Third, reinforcement of service for support the habitability and design manual for secure uniform quality. Forth, investment in the environment-friendly housing and new recycling energy. Fifth, reinforcement of organizational power for improving production capability.

The best feature of Hotels is they have 24 business hours providing various services. But Interior designers can't change space to answer every demands, it's mood can be changed by lighting design. Especially guest rooms have complex functions like space with habitability and office use. Well planed lighting design in guest rooms is an essential element to help creating interior space in designer's intention with cozy feeling. Here this study is purposed to present a desirable lighting environment satisfying future-oriented function and design throughout the latest examples' analysis of guest room carrying out various functions in hotels.

A previous exo-terrestrial life-detecting experiment, which was conducted on Mars, sought to detect the products of glucose metabolism, the most common biological process on Earth (Viking biological experiment). Today, glucose metabolism is not considered the universal process of life survival. As NASA plans to launch an orbiter mission in the near future (2020s, the Clipper) and ultimately conduct a lander mission on Europa, a detection experiment that can give broader information regarding habitability is highly required. In this study, we designed a life-detecting experiment using a more universal feature of life, the amphipathic molecular membrane, theoretically considering the environment of Europa (waterdominant environment). This designed experiment focuses on finding and profiling hydrophobic cellular membrane-like microstructures. Expected results are given by conceptual data analysis with plausible hypothetical samples.

Vehicle's airtight integrity is a very important factor that greatly affects passenger's habitability. However, when a door is closed, the pressure in the passenger compartment increases due to the vehicle's airtight integrity. That pressurizes the eardrums of the passenger, and makes passenger unpleasant. Thus, in this study, the configurations of air ventilation hasve been investigated to reduce pressure in the passenger compartment. Truck cab is utilized to measure the pressure in the passenger compartment. Various kinds of air ventilations are considered to find out optimized pressure in truck cab when a door is closed.

Habitability is one of the most important points when a passenger ship is cruising. In particular, anti-vibration design should be considered preferentially to offer passenger a comfort cabin and leisure space. But, a passenger ship is different from a general commercial ship in the view point of the structural arrangement. It is restricted within narrow limits to reinforce wide panels and local structures of a passenger ship because of its interior design. Moreover, the allowable vibratory limits for a passenger ship are much lower than those of a commercial ship. In this study are introduced the procedure of the vibration analysis, the structural improvement method for prevention of vibration and the results of vibration measurement during exciter test and sea trials.

Underwater radiated noises from marine vehicles are mostly due to the propulsion systems. Recently, the propeller noise problems are becoming crucial issues in terms of habitability of passenger ships. Especially in military area, propeller noise is directly related to the survivability of submarines and warships, and thus propeller noise analysis and reductions are very important. Generally, propeller noise can be classified into non-cavitating noise and cavitating noise which is dominant. In this paper the methodology of propeller noise analysis is announced and new approach to consider scattering effect is proposed. Unsteady blade surface pressure and sheet cavity volume analyzed with potential based panel method are used as noise source.

Noise reduction and control is an important problem in the performance of underwater acoustic system and on the habitability of the passenger ship for crew and passenger. Furthermore, sound generated by a propeller is critical in underwater detection and is often related to the survivability of the vessel especially for military purpose. Generally propeller noise is often the dominant noise source of marine vehicle. The flow field is analyzed with potential-based panel method, and then the time dependent pressure and sheet cavity volume data are used as the input for Ffowcs Williams-Hawkings formulation to predict the far-field acoustics. Through this study, the dominant noise source of underwater propeller is analyzed, which will provide a basis for proper noise control strategies.

This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of row-rise housing as an alternative housing type on hilly sites. Several generic solutions are proposed by considering the density of dwelling, parking plans, exterior space and access patterns, making full use of geographical features of hilly site and existing facilities. In order to promote development feasibility of proposed plans, the efficiency of the proposed techniques are verified in terms of development density, enhancement of community space, habitability of housing.
