Despite various forms have been developed and applied to ship hull forms, the superiority of hard chine type over other forms of fishing boat has been recognized so far. As one of the ways of forms for new concept fishing boat, this paper presents the result of a performance evaluation for newly developed forms of hull, appendage and deck house, which features that have esthetic forms.

A series of wind tunnel tests, including 1:50 sectional model tests, 1:50 free-standing bridge tower tests and 1:70 full-bridge aeroelastic model tests were carried out to systematically investigate the aerodynamic performance of the Hong Kong-Zhuhai-Macao Bridge (HZMB). The test result indicates that there are three wind-resistant safety issues the HZMB encounters, including unacceptable low flutter critical wind speed, vertical vortex-induced vibration (VIV) of the main girder and galloping of the bridge tower in across-wind direction. Wind-induced vibration of HZMB can be effectively suppressed by the application of aerodynamic and mechanical measures. Acceptable flutter critical wind speed is achieved by optimizing the main girder form (before: large cantilever steel box girder, after: streamlined steel box girder) and cable type (before: central cable, after: double cable); The installations of wind fairing, guide plates and increasing structural damping are proved to be useful in suppressing the VIV of the HZMB; The galloping can be effectively suppressed by optimizing the interior angle on the windward side of the bridge tower. The present works provide scientific basis and guidance for wind resistance design of the HZMB.

This study focuses on Korea's traditional-style soryebok, in terms of its foundation, progression, and structural features. The research methods employed here include literature analyses of relevant laws and an official daily gazette, and practical analyses of artifacts and photographic documents. Especially, the artifacts of heukdannyeong(black uniform for officials with a round neck) in the form of chaksu(tight sleeves) were examined, which was regulated as soryebok in Eulmiuijegaehyeok. The term "soryebok" firstly appeared in "使和記略"(Sahwagiryak) written by Park Yeong-hyo, a foreign envoy to Japan, in 1882. Emperor's invitation written in the book asked him to wear daeryebok at the ritual and soryebok to the banquet. Soryebok was not adopted in Gapshinuijegaehyeok in 1884. However, several illustrated documents of the modern banquets at that time reveal that sabok, which was included in the 1884 reform, was used as soryebok. According to the Gapouijegaehyeok in December 1894, courtiers were required to wear heukdannyeong as daeryebok, and add juui(topcoat) and dapho(sleeveless coat) as tongsangyebok when they visited the royal palace. In Joseon's first daeryebok system, the term "tongsangyebok" that had been used in Japan was employed before soryebok was used. According to Eulmiuijegaehyeok in August 1895, the term "soryebok" originated from a costume ritual for courtiers of the Joseon Dynasty. Soryebok featured heokbannyeong chaksupo, samo (winged hat for officials), sokdae(belt), and hwaja (shoes for officials). There are around 24 artifact pieces of heukdannyeong in the form of chaksu(tight sleeves) in the following locations: garments of Prince Heungwangun and Wansungun, the court artifacts, Korea University Museum, Yun Ung-ryeol's family housed at Yonsei University, and Kyungwoon Museum. Artifacts have mu(godet) pulled back and a topcoat-like triangular mu. In conclusion, heukdannyeong, traditional-style soryebok has significance in the history of modern dress because streamlined traditional clothes and newly introduced Western dress system were able to be combined.
