From middle of 90's, SCM had emphasized the importance of connection of all companies which participate to a market, and outsourcing has emphasizes the slim structure of companies for pursing cost reduction and service improvement. But outsourcing as '2-1=1' and integration as '1+1=2' not adapt to the advanced market but return to the former state. Besides, it is impossible of subcontractors and logistics companies to execute these strategies which are win-win strategy and outsourcing. So many logistics companies have sharp competition in price recently. Therefore logistics companies have increased the need for a profitable business model and strategy. This paper researches the limitations of logistics market and redefines the role of logistics through the evolution of logistics. Also this paper proposes new role(Logister) and structure(Velcro structure) for not maker-oriented logistics but market-oriented logistics. The introductory case study will help to understand 2 terms(logister and velcro structure).

A seismic strengthening method using Velcro is proposed to improve the seismic performance of columns in RC frame structures. The proposed method was evaluated experimentally using three fabricated RC specimens. Velcro was wrapped around the columns of the RC-frame specimen to prevent concrete spall falling. The reinforcing performance of the Velcro was determined from comparison of results on seismic performance (i.e., strength, displacement, failure mode, displacement ductility capacity and amount of dissipated energy). As the displacement of the reinforced specimens was increased, the amount of dissipated energy increased drastically, and the displacement-ductility-capacity of the reinforced specimens also increased. The final failure mode of RC frame structure was changed. As a result, it was concluded that the proposed seismic strengthening method using Velcro could be used to increase the displacement ductility of RC columns, and could be used to change the final failure mode of RC-frame structures.

다층 구조물의 경우 1층이 연약한 경우 지진 시 1층에 변형이 집중되어 기둥 부재에 심각한 손상이 발생하거나 파괴되어 구조물이 붕괴하는 사례가 발생하게 된다. 국내의 경우 포항지진 당시 필로티 구조물의 손상사례를 예로 들 수 있다. 2016년 국립재난 안전연구원의 "국내 비내진 건축물의 내진보강공법 조사 및 소요비용 분석 연구"에 따르면 민간 철근콘크리트조 건축물 중 주택의 내진화 비율은 38.3 %고, 그 중 2층 구조물 7.1 %에서 6층 96.3 % 그 외 99.4 %로 2~5층 구조물의 경우 내진비율이 50 %이하로 저조한 것으로 보고하였다. 이에 정부는 지원사업을 통해서 내진화율을 개선코자 하고있으나, 종래의 보강법은 여전히 시공비용이 고가이고 긴급시공이 어려운 단점이 있다. 따라서 본 연구에서는 2014년 국토교통부의 연구사업을 통해서 개발된 저렴하고 긴급시공이 가능한 벨크로를 사용한 내진보강법의 성능을 개선하고자 벨크로와 콘크리트 기둥 사이에 고발포의 경질 우레탄 내부 충진을 통해서 벨크로의 초기긴장력을 도입하고, 이를 통해서 콘크리트 구속효과에 따른 벨크로의 연성보강성능 개선을 목표로 이를 평가하기 위한 실험을 수행하였다. 시험체의 최대 연성도를 통한 평가에서 벨크로 내진 보강재의 최대 연성도 증진 효과를 재확인할 수 있었다. 에너지 소산 능력을 통한 평가에서는 VELCRO1 대비 VELCRO2 눈에 띄는 개선을 보인 반면, VELCRO1와 VELCRO2 시험체의 최대 연성도는 큰 차이를 보이지 않았다. 결과적으로 충진재가 사용된 VELCRO2 시험체에서 에너지 소산 능력은 크게 증진되었으나, 최대 연성도 평가에서 최대변위(∆_max)의 증가가 크지 않은 것을 확인하였다. 따라서 내부 충진재 재료의 개선과 균일한 충진재 시공을 개선의 필요성이 확인되었다.

The viewpoint of growth pursuit is changed to that of life quality's and happiness' pursuit by modern people. Modern people in digital environment, tired of fast-changing and oppressive daily life, prefer well-being trend providing tranquility and relaxation. Well-being is related to digital, because negative influences of digital lead human-oriented, environment-friendly well-being design. Therefore the purpose of this study is to research and analyze the relation of well-being fashion design and digital environment through case study in contemporary well-being fashion design. The results of this study are as follows: 1. This study shows that the attributes of digital environment make up function-intensive, interactivity, mobility & nomad, human & emotion-oriented and environment-friendly. And this study shows the design characteristics of digital environment consist of function-intensive design by digital convergence, open structure design for interactivity, modular design for mobility & nomad, emotion-oriented & multi-sensory design and environment- friendly design. 2. Function-intensive design in modem well-being fashion composed of vogue of caports style(casual+sports), practical use of multi-functional new-healthy textiles, and popularity of many style's mixture at once. Open structure design consist of wrapover design, use of transparent materials. Modular design are layered styling, practical use of zipper and velcro. Emotion-oriented & multi-sensory design are constitute of fad of wrinkle materials, application of bright & vivid tone, personal color and family look. Environment-friendly design in contemporary well-being fashion are comprised in use of natural color, re-advent of natural floral motif and eco-design.
