As marine leisure is getting popular around the world, people's interest in cruise ship is increasing rapidly. Now it became possible to make cruise ship with Korean technology, as a result of continuous research and development. However, as cruise ships are getting bigger and more popular, new cruise interior design is required to satisfy various clients' aesthetic and functional demands. Therefore, more researches for cruise interior design are needed. The purpose of this study is to analyze the characteristics of planning and design of passenger's cabins in cruise ship. The scope of this research is limited to the types in the 2004-2010 in Large Cruise Ships. Method of this study are document study and case study, in particularly, case study is conducted for the specific design methods through case analysis. The results of this study are as follow : One of the transitions in the cruise cabin designs is that cabins with balconies occupy a large portion of the entire cabins. As the functions of these balconies are diversifying, more distinctive forms of balcony are showing up. In particular, the cabins which are connected to public space differentiate themselves from those with the same rates; it meets the demands of the clients who require high quality services. In terms of cabin design, a futuristic, distinctive cabin that has incorporated will be a very important function in determining the value of the cruise ship. Based on the results of this research, application of the rapid changes in cabin design and studies about more diversified and advanced design are required.

In this study, shape optimization was performed to improve the vibration isolation capability of an anti-vibration rubber assembly, which is used in the field option cabin of agricultural tractors. A uniaxial tension test and biaxial tension test were performed to characterize the hyper-elastic material properties of rubber, and the data were used to calibrate the material model used in the finite element analyses. A field test was performed to quantify the input excitation from the tractor and the output response at the cabin frame. To account for the nonlinear behavior of rubber, static analyses were performed and the load-displacement curve of rubber was derived. The stiffness of the rubber was calculated from this curve and input to the harmonic analyses of the cabin. The results were verified using the test data. Taguchi's parameter design method was used to find the optimal shape of the anti-vibration rubber assembly, which indicated a shape with reduced stiffness. The vibration of the cabin frame was reduced by the optimization by as much as 35% compared to the initial design.

The demand for the stable and comfortable cabin of a high speed passenger ship is increasing. The study on shipboard comfort has been mainly concentrated on the motion control of a whole hull body. In this study, however, a new control system operated by two parallel robots (3RPS, 3SPR) such as the active suspension system of motor vehicle is proposed. The goal of this control is keeping zero velocity of the upper robot (cabin) although the lower robot (ship) is moving by the waves. Jacobian matrix was used to design the controller, From the simulation results, the remarkable reduction of motion of the cabin (upper platform) was observed. The 3SPR parallel robot shows better performance compared to the 3RPS robot.

A finite analysis of tractor cabin for ROPS design was performed. Finite element model was made to take account of the tractor cabin structures. Four tests were defined in OECD standard; (1) longitudinal loading (2) rear crushing test (3) side loading (4) front crushing test. The results of four independent analyses and sequential analysis are compared with test results.

Zero tail type mini excavator is small in size and capacity compared with medium or large excavator. Therefore noise and heat problems are major issues in design due to layout of each components such as engine and hydraulic module. It is necessary to assure reduction of noise and vibration in construction machine, due to be enforced regulation for high noise construction machinery at home and abroad. The objective of this study is to provide basic data which is apply to predict noise effect in detail design stage by estimating noise of cabin for zero tail type mini excavator.

Purpose - In order for companies to be competitive and adapt to the trend of development, it is important for many airlines to secure outstanding human resources and the need to nurture them. It can be expected that by systematically analyzing and organizing the characteristics and types of competences considering the duties of the airline cabin crew, the personal and organizational capacities of the cabin crew can be defined and presented theoretically. Research Design, Data, and Methodology - This survey was conducted over a seven-month period from February 1 to September 30, 2018 and was designated as a domestic airline flight attendant. Direct visits to Incheon International Airport and Gimpo International Airport were also conducted through an online questionnaire. A total of 515 questionnaires were used for empirical analysis. To verify two hypothesis of this study, a regression analysis and exploratory factor analysis (EFA) were performed using SPSS WIN 26.0. Results - Analysis on the impact of personal capacity of airline cabin crew on job satisfaction showed that technical competence, knowledge capacity and ability capacity, which are sub-factor factors of personal capacity, had a positive effect on job satisfaction. Recovery resilience also plays a positive role in relationships between individual competence and job satisfaction. Conclusions - It has been empirically analyzed that the personal characteristics of the airline crew have a significant effect on flight attendant's job satisfaction. It can be seen that flight attendants tend to perform well beyond what is required in their duties, and that active and confident cabin crew members tend to perform well in the direction of improving their duties, and are also highly satisfied with their duties.

The ROPS of an agricultural tractor is designed to protect its driver when the tractor overturns. Although the current OECD tests to determine whether the ROPS meets the requirements of the OECD regulation are desirable, they need long time to test. We experimental time and effort by using CAE. We conducted a finite element analysis for the ROPS design of a Dae-Dong tractor cabin in an attempt to reduce the design and manufacturing time. This study shows the interpretative skill using MARC(v.2000) for designing ROPS and difference between the results of testing and FEA. Design process is generally divided into two phases: a concept and a detail design. The concept design uses simple analysis to predict structural behavior, whereas the detail design involves a finite element analysis performed by the results of the concept design. This study focused on the detail design and used Patran(v.2000r2) and MARC(v.2000) of the MSC software corporation. The model consisted of 4812 elements and 4582 nodes. Four tests. specified in the OECD standards, were performed: (1) longitudinal loading test (2) rear crushing test (3) side loading test (4), and front crushing test. Independent analyses were also performed for each test, along with a sequential analysis. When compared, the results of the independent and sequential analyses were found to be similar to the test results.
