Recently, Statistical Energy Analysis(SEA) is being increasingly applied to describe vibro-acoustic behavior of complex structures, such as air plane, automobile, ship, building. In this paper, we discuss the application of SEA to predict the interior noise for KTX train. To validate the SEA model of KTX train, calculated the interior noise for motorized car is compared to measured one. Finally, the reduction measures of interior noise for KTX are also discussed.

This study compares optimization algorithms for efficient estimations of ship's hydrodynamic coefficients. Two constrained algorithms, the interior point and the sequential quadratic programming, are compared for the estimation. Mathematical optimization is designed to get optimal hydrodynamic coefficients for modelling a ship, and benchmark data are collected from sea trials of a training ship. A calibration for environmental influence and a sensitivity analysis for efficiency are carried out prior to implementing the optimization. The optimization is composed of three steps considering correlation between coefficients and manoeuvre characteristics. Manoeuvre characteristics of simulation results for both sets of optimized coefficients are close to each other, and they are also fit to the benchmark data. However, this similarity interferes with the comparison, and it is supposed that optimization conditions, such as designed variables and constraints, are not sufficient to compare them strictly. An enhanced optimization with additional sea trial measurement data should be carried out in future studies.

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.

The space of leisure boats & yachts is formed by interior design elements and shapes are formed by combination of those elements. By means of configuration of the design elements, space is made in a ship and patterns in an inside space are made through production. These space can be categorized as (1) cabin(common cabin, staterooms, one-cabin), (2) salon, (3) galleys & dinette, (4) heads(showers, toilets, bidets, sinks), (5) cockpit, (6) wheelhouses, navigation stations, (7) fore peaks, (8) engine room, (9) deck etc. Interior materials are classified into (1) walls(bulkheads & lining wall), (2) floors(sole), (3) ceilings(overheads), (4) doors & windows, (5) furniture, (6) lightings and (7) Hardware & decoration in large, medium and small sizes, which constitute interior design elements of a leisure boat & yacht. The materials used in leisure boats & yachts have properties of lightweight, noise and vibration resistance, fire & flame retardant, stability, strengths, lifespan, appearance and special operation in construction.

The purpose of this study was to investigate user satisfaction by identifying the problems and suggesting Improvement plans of interior design in the accommodation area of Ro-Pax ships. First, the characteristics of Ro-P ax ships' accommodation area through previous studies and references, and then a field survey was conducted on seven kinds of Ro-Pax ships. Based on the field study, a questionnaire survey was administered targeting 38 experts involved in passenger ships who indicated that public facilities were the most unsatisfactory of interior design in accommodation areas. As a result of Multiple Linear Regression Analysis, the satisfaction of color showed the highest influence on user satisfaction in accommodation areas, and required the standard of the interior design in accommodation areas. The suggested results of research were the types and layout of public facilities, improvement of color design, provision of interior design standard for accommodation areas, and improvement plans for interior design of Ro-Pax ships.

The cruiser trip which can have various experiences in a short time is growing as the best tourism package because there is less leisure time in contrast of the increased income in 21C. in other words, as the demand of the tourist goes up, the number of ships built newly is increasing. The order of the ship keeping first and second rank in Korea has arranged a long-term strategy in order to get into the global market with the cruiser with the high value added. They also set the objective related to the cruiser design and skillful construction work. We need to observe the change and trend of the cruiser with a care at this time when the cruiser industry is launched out. In this study, the cruiser industry is divided by four periods: the spring time, the depressed time, the developing time and the peak time, on the basis of the trend of the development and the change of space structure. In addition, it was analyzed in this study that there were the various trends such as the ratio, the structure and the type of the space as well as the interior plan in the passenger's residential place The aim of this study is to present the fundamental material about the interior plan to prepare for building the domestic cruisers in a foreseeable future.

year in Europe and Asia. Therefore the introduction of new ships continues at a great rate. There is a definite trend toward either large ships or smaller, more luxurious vessels in cruise industry. The day to design and build the large cruise vessel is coming to Korean shipyards, sooner or later. The most important thing to design large cruise vessel is to have a correct comprehension about the feature of cruise vessel, especially of the passenger accommodation area in cruise vessel. This paper is on the spatial features of the passenger accommodation area in cruise vessel. General arrangement drawings, deck plans and technical data of the newest large cruise ships are analysed to understand the spatial features and induce the direction of space planning of passenger accommodation area for the large cruise ship of tomorrow.

According to a progress in the quality of life and economy, recent years have seen an increase in interest in the cruise travel. However, it is important to provide them the optimum embarkation environment since there are to be many and unspecified persons staying for a long period on the cruise ship. In the architectural design field, a wide range of efforts are being recently made to meet customer's requirements by considering the rapidly changing society, environment, and economic trend. The most representative one of such efforts is the inclusive design concept. This concept means to perform design satisfying all the function, convenience, aesthetic appreciation, and utility, regardless of sex, age, ability, nationality, cultural background or any kinds of disabilities. Regarding this trend, the convenience-oriented design of a cruise ship using the inclusive design concept was performed in this study. To do this, the composition of cabins and swimming pools, and the exterior of the cruise ship were classified into several groups through literature survey. Then, in the point of view of the inclusive design concept, inconvenience matters of passengers about the cabins, swimming pools, and exterior were also extracted from literature survey. Next, basis designs for them were selected among the classified groups in order to solve such inconvenience matters. Finally, the convenience-oriented design of the Emerald Princess Cruise considering the inclusive design concept was performed by applying the basis designs. As a result, we can see that the inclusive design concept can be applied to cruise ship design.

As coffee's taste and scent are emphasized, and interior atmosphere has changed along with sale of brand's own products, there are also epochal trend changes in interior. So, changes within the space should be focused onto open type self coffee shop, a new cultural space distinguishable from existing coffee shops. Therefore, in this study, the following results could be obtained by performing customer-centered, spatial structural characteristics research on 5 take-out coffee shops opened after 2005 that are practicing self service in Busan and Gyeongsangnam-do regions. In this study, it was shown in the above results that location of the entrance, kitchen, and condiment bar, area per person, size and positioning of furniture, area of windows and doors, etc have strong influences for self service which customers themselves carry their food. Therefore, in planning the interior of self coffee ship in the future, presentation of more effective and practical space based on this analysis will be required.
