일반적으로 사용되는 비탈면 보강공법은 중력식 혹은 가압식 네일링, 앵커 등이 있다. 이들 공법은 주입재 주입압력이 중력식무압 혹은 낮은 압력의 가압에 의한 것으로서, 실제로 단층파쇄대, 붕적층, 이완 및 절리 등이 발달한 지반에서는 일정압력의 가압주입에 의한 지반보강과 보강재에 의한 네일링 효과를 동시에 기대해야 한다. 본 사례에서는 가압주입의 효과를 높이기 위해 보강구간을 일정한 간격으로 나누고 구간별 별도의 주입펌프를 연결하여 보강길이 전구간을 동시에 주입하는 멀티패커시스템(MPS)공법을 소개하고자 한다.

The purpose of this study was to analyze critical needs and demands for the multifunctional traveler's jacket and to develop design prototypes based on the findings from the analysis. A self-report questionnaire with the stimuli was applied. Total 163 travelers were purposively sampled for the survey and the data were analyzed quantitatively as well as qualitatively. The results were as follows: 1. The respondents were divided into three groups - "digital-functionality-needs group", "non-digitalfunctionality-needs group", "no-need group", according to their preference and needs for the multifunctional traveler's jacket. 2. The three groups were analyzed (1) to have meaningful differences in experiencing inconvenience in their traveling, (2) to have statistically significant differences in their needs for the multifunctional traveler's jacket, (3) while some imperative consensus in their needs were found in part. 3. Based on the findings of the analysis mentioned above, three design prototypes were developed and visualized with conclusion.
