Recently, it is much more required to approach the accurate shaft alignment analysis according to the tendency of active showing in large container vessel and that of the heavy weight of propeller in connection with it. Shaft alignment calculation lies upon how the pressure apply on bearings properly in operation of main engine and how the stress of shaft puts within that of limit of bearing material and how the movement of shaft is prospected owing to propeller forces and moments. Therefore, we have conducted the shaft alignment calculation of very large container vessel considering the deformation of hull structure and the propeller forces and moments and the static and dynamic condition of shaft. The calculation results show the pressure distribution of aft bush and the movement of shaft in bearing. The shaft alignment calculation helps the stable application of shaft alignment, which was proved in sea trial.

The purpose of this article was to determine how the current auto mechanic's coverall restricts movements, to develop prototype coverall, and finally, to improve working efficiency. To investigate the problem and complaint of current coveralls, 35 mechanics were interviewed. Video captured method was used to analyze the representative movement. Based on the previous investigation, the prototype coverall was developed. Pleats and band were inserted on each side of the back, under the armhole, and the back waist area for flexibility. To analyze the mobility of current and prototype coveralls objectively, range-of-motion of selected movements was measured by Leighton flexometer and goniometer. Also, wearer acceptability scale was tested to investigate subjective preference of current and prototype coveralls. As subjects, 10 auto mechanics were participated. Order of testing was randomized. ANOBA and LSD were used for statistical analysis. As a results, prototype coverall was significantly different from current coverall at all test movements. Also, prototype coverall was significantly different from current coverall at 13 scales among 23 subjective scales. The results identified that prototype coverall design improved auto mechanic's body movement and subjective acceptability.

In this study, we provided examples of light emitting diodes (LEDS) in everyday sportswear and confirmed their usefulness to provide functionality, aesthetics, and entertainment. One type of sports jacket and one set of sportswear were designed and manufactured using LEDs and made available to the general public for use in daily life to provide functionality, aesthetics, and entertainment. To generate digital images, a textural design of a circuit image was developed and applied, and the LEDs were placed on the developed textile in an attempt to merge the LEDs with the design. The product was equipped with a tilt sensor and produced a randomly lighted jacket with LEDs that adjusted according to movement. The LEDs turned on in the desired location by lifting the arm during night sports activities. The tricolor of NEO PIXEL LEDs lit randomly and its rhythmical design could be maximized when moving or exercising outdoors, and also for entertainment. The role of creating interest for lively and unexpected pleasures and the aesthetic beauty of LED lights were also obtained. There was no inconvenience or restriction of movement by LEDs or internal structures using the hot-melting technique, and the removable attachment of the device made it easier to wash.

This study analyzes a new fashion phenomenon for critical fashion. Critical fashion is a message-centered fashion that delivers consciousness and sociocultural issues for contemporary society. The research method for this study combined literature reviews and case studies along with a research scope, that reviewed aspects of critical fashion through works, presentations, and images of collections, various media, and joint projects from the 2000s to the present day. This study indicates that critical fashion exhibits a conceptual pattern that metaphorically expresses the message of designers' perspectives on society and the fashion system. Critical fashion designers' socially critical messages began to emerge in avant-garde fashion influenced by avant-garde art movement that then developed into a conceptual fashion heavily influenced by conceptual art movement before it evolves into concepts of critical fashion. Critical fashion has been influenced by community-oriented critical art, which signifies that the characteristic of criticism of an art system is expressed through the language of fashion. In conclusion, critical fashion resists the idea of the integration of a cultural industry whose homogeneity is continuously collapsing the differences for the purpose of consumption and challenges to the established fashion system.

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.
