The purpose of this study is to analyze the characteristics and symbolism of peony, the traditional noble flower, create knit fashion designer applying the aesthetic beauty of flower, and suggest the various possibility of developing knit fashion design. As for the study method, the study conducted review on literature and previous studies to investigate on history, characteristics, symbolism of peony, and examined various expressive technique through previous studies about fashion design using flower images. To express characteristics of peony in three dimensions, the study investigated and reflected on crochet expressive technique to design 4 women’s knitwear. The results are as below. First, as shape of peony is big, voluminous, fancy and noble, it symbolizes wealth and beauty. Including red which is the generally known color of peony, there are yellow, white, pink, purple, green, blue, black, gray, white purple, white color. This study reflected characteristics and symbolism of peony and created knit fashion design applying abundant aesthetic characteristics of flower. Second, crochet method is advantageous as it is operable with thread and hooked crochet hook without time and space restriction, it can create unique fashion design. Crochet knitting on hand knit can diversity changes to express relief textures, and as there is no limit in size, it can be applied to small props to big pieces. This study suggested the various possibility of knit fashion design development and various expressive possibility on modern fashion design.

우리나라에서 다랑어 선망어업은 국내 원양산업 중 업종별 생산량 1위의 업종으로, 1980년대 중 후반부터 연구가 지속적으로 수행되어왔으며, 기술의 현대화 연구가 활발히 진행되어왔다. 하지만, 어선에 탑재되는 보조작업선들은 원양어업에서 중요한 역할을 맡고 있음에도 관련 연구가 미흡한 실정이다. 이에 본 연구에서는 보조작업선들 중 네트보트의 추진기를 프로펠러에서 워터제트 형태로 변경하고, 그에 따른 선형 변환을 통한 선체 부가저항 감소 및 운항성능을 향상하고자 하였다. 이를 위해 전산수치해석을 통해서 선박의 유체 성능 변화를 계산하였으며, 또한 기존 선형 및 추진기 변화 선형에 대해 모형선 수조시험을 수행하여 속도별 저항성능 비교를 수행하였다. 수치해석 및 1/7의 축소모형의 수조시험 결과, 기존의 네트보트 대비 45~58% 저항성능이 크게 향상되었으며, 이는 철망 제거에 의한 단순 침수표면적 및 선형개선에 의한 저항성능 향상을 확인하였다.

Recently, researches on light weight of vehicles have been actively carried out to reduce fuel consumption. Researchers have generally attempted to replace metal materials with composites, but these materials do not meet the required strength and rigidity of the vehicle and require a variety of design approaches. In this paper, deck assembly of truck was compared and compared with assembly using existing floor as Apitong, and it was verified by structural analysis and modal analysis. To do this, we measured the mechanical properties of the material through tests and evaluated the safety of the Deck Assembly through maximum equivalent stress, total deformation, and safety factor values. In addition, the fit of the hybrid deck assembly structure was evaluated by measuring the approximation of the analysis by single component assembly test.
