        A New Framework of Design Management and Three Additional Requirements To Apply Design Management to Korean Companies: Experience Design, Collaboration, and Trial and Error

        주재우,이희진,박정호,주재우 디자인융복합학회(구.한국인포디자인학회) 2018 디자인융복합연구 Vol.17 No.6

        The present research has two objectives. First, we introduce a new framework of design management proposed by Heather Fraser, the Director of Rotman Designworks. It comprises three gears: (1) user understanding, (2) concept visualization, and (3) strategic business design. Second, we investigate the key requirements that are necessary to apply the new framework to Korean companies. We collected fifty reports about the five special lectures from a new product development course at a university in Korea. These lectures were given by three designers and two product managers. We used interpretative analysis and followed three process of qualitative analysis of transcription, coding, and theme discovery. We derived specific requirements for applying design management to Korean companies: (1) experience design, (2) collaboration, and (3) trial and error. We introduced a novel design management framework and clarified the requirements how to successfully apply it to Korean companies. These findings imply that, firstly, executives and practitioners need to improve mutual communication and, secondly, corporations and agencies respect each other in their partner relationships.

      • 有機質土의 剪斷特性에 관한 硏究

        朱宰佑 순천대학교 공업기술연구소 1991 工業技術硏究所論文集 Vol.5 No.-

        This study aims at scrutizing the shear characteristics of three kinds of organic soils located near the southwestern coast of Korea. Loboratory tests such as unconfined, triaxial compression were performed. The main conclusions analyzed are as follows: 1. The existence of a critical state line was confirmed in organic soils as in clayey soils. 2. The more organic contents the specimen included, the higher unconfined strength it showed, which is understood to be due to tensile strength resulting from fiber material that is not yet decomposed in organic soils. 3. The effective internal friction angle, Φ was increased in the order of the organic contents with the cohesion intercept nearly zero. Especially the specimen of I-Ri(IR) showed the small cohesion but a large effective internal friction angle(55°), which is considered due to the effect of fiber.

      • 지오그리드 매트리스기호의 전파듣력에 관한 연구

        주재우,장용채,박종범,Ju, Jae-U,Jang, Yong-Chae,Park, Jong-Beom 한국지반공학회 1998 지반 : 한국지반공학회지 Vol.14 No.4

        지오그리드를 이용한 입체적인 매트리스기초는 연약지반의 지지력을 증가시키기 위해서 증증 사용되며 그 효과를 인정받고 있다. 지오그리드-매트리스 시스템이란 그 자체의 강성에 의해 하중을 보다 더 넓게 기초지반에 분산시킴으로서 지지력의 증대효과 및 침하억제효과를 가져오는 공법이다. 그러나, 이에 대한 메카니즘은 아직 명확하게 규명되어 있지 않다. 본 연구에서는 지오그리드 매트리스기초 아래 전파응력분포 특성을 파악하기 위해 모형실험을 실시하였고, 실험에서는 지오그리드 매트리스기초와 두께 및 지지하는 기초의 강성 등을 영향인자로서 고려하였다. 실험결과로부터 매트리스기초하의 전파응력분포 특성을 파악하였고, 지오그리드 매트리스기초 설계시 지지력을 구할 수 있는 방법을 제안하였다. Solid mattress foundation using geogrid has often been used on soft grounds to increase the bearing capacity, and its effect has received much recognition. Geogrid-mattress system is the method of construction which increases the bearing capacity and the effect of controlling settlement by dispersing load to wider foundation through its stiffness. But ifs mechanism has not been examined exactly yet. considered to be influential factors in the experiments. As a result of the experiments, the characteristic of dispersing stress under mattress foundations was understood and the way of calculating the bearing capacity in designing the mattress foundations was suggested.

        한중관계에서 북한 요인이 주는 전략적 함수관계 연구

        주재우 중국지역학회 2022 중국지역연구 Vol.9 No.3

        The paper explores the impact North Korea as a factor on the ebb and flow of South Korea-China relations during the past thirty years since the normalization of the relationship in 1992. Aside from its respective domestic politico-social factors, North Korea as one of the outside factors affects the development of the bilateral relationship of the South and China. The North apparently needs to survive against any negative spinoffs possibly engendering from close relationship of the two and compelled to intervene to distance the two for its own interests. The power structure of the relationships of the states in the Northeast Asia dictates that each country’s external relations must be looked at in a triangular relations for its respective bilateral alliance relationship. South Korea and China are subject to this demand for its alliance with the United States and the North, respectively. The paper hopes to offer a base that will facilitate the predictability of North Korea’s behavior in the relationship between the South and China. 본 연구는 지난 30년 동안 북한이 한중관계의 부침(浮沈)에 한 요인으로 어떠한, 어떻게 영향을 미쳤는지를 분석하였다. 한중관계의 부침에는 한중 각국의 국내정치·사회적 요인의 영향도 있었지만 대외적으로 북한의 영향력을 배제할 수 없다. 이는 남북관계, 북중관계에서 생존하려는 북한이 한중관계의 발전으로 입을 수 있는 부정적인 영향 및 결과를 최소화하려는 생전전략에서 기인한다고 본 문은 가정한다. 특히 여기에 북한 핵문제로 인한 미국의 요인도 추가되면서 한미관계와 미중관계가 북한의 대외 행위에 영향을 주었다. 그러면서 한중관계에서 북한은 미국 요인의 영향에 따라 변화하는 남북관계와 북중관계를 자신의 안보이익에 이용하려는 전략적 계산에 따라 한중관계의 부침에 영향력을 발휘하였다. 따라서 본문은 이 같이 다양한 3국간의 역학관계를 이른바 ‘삼단논법’의 논리에서 조망하고 다양한 3국 관계 속에서 북한이 한중관계의 부침에 미친 영향을 분석하고자한다. 이를 통해 3국간의 역학관계의 속성을 파악함으로써 한중관계와 북한 간의 상호작용이 보다 예측 가능한 기초를 제공하는 것이 본 연구의 목적이다.

        화강토와 표준사를 이용한 토목섬유의 인발시험결과 비교

        주재우,박종범,김장홍,송춘석,백경종,Ju, Jae-Woo,Park, Jong-Beom,Kim, Jang-Heung,Song, Chun Seok,Baek, Kyung-Jong 한국지반신소재학회 2005 한국지반신소재학회 논문집 Vol.4 No.2

        인발 저항각이라는 새로운 개념은 토목섬유로 보강된 지반에서 인발 시험을 행할 때 발생되는 마찰력, 점착력, 수동저항을 포함하는 것이다. 인발 면적을 계산함에 있어 분포 면적법을 사용하였는데, 이는 그리드에 발생되는 인장력 곡선을 이용하는 방법이다. 분포면적비는 화강토나 표준사 지반에서 거의 비슷한 결과를 나타내었다. 인발 저항각은 낮은 구속하중인 $0.2kg/cm^2$일 때는 마찰각보다 더 큰 값을 보이지만, 높은 구속하중인 $0.8kg/cm^2$일 때는 마찰각보다 더 작은 각을 보였다. New concept called the pullout resistance angle has been used to express the friction, cohesion and passive resistance by pullout test at geosynthetics reinforced soil. And also in order to calculate the pullout area, the distribution area method has been used, which is a method of using the curve of tensile force exerted in geogrid. The distribution area ratio showed nearly the same result in the two kind of soils, the granite soil and the standard soil. The pullout resistance angle showed the greater value than friction angle of soil in case of low confining stress of $0.2kg/cm^2$, while it showed the smaller angle than friction of soil in case of high confining stress of $0.8kg/cm^2$.

        고함수비를 가진 준설토의 압밀특성

        주재우,정규향,김영규 한국농공학회 2003 한국농공학회논문집 Vol.45 No.5

        Dredged soil from sea has much higher water content than liquid limit of clay and even if small loads apply, it will suffer a great settlement. Therefore it is very difficult to perform a consolidation test with general consolidation apparatus because of high water content. In this study Rowe Cell Apparatus consolidation tests have been performed with 1 remolding clay of water content 56% and 4 slurry clays of a water content of 100%, 120%, 133% and 150%. From the test results the consolidation characteristics such as compression index, secondary compression index and consolidation coefficient have been investigated with a variation of water content of dredged soil. The equations to get consolidation constants such as a compression index, a consolidation coefficient have been proposed with the field water content.

        해성점토의 반복재하 및 제하압밀특성

        주재우,김재영 한국농공학회 1982 한국농공학회논문집 Vol.24 No.3

        This study was conducted to investigate the consolidation characteristics of repeated increasing and decreasing load m marine clay. Consolidation test was performed by the whole repetition of increasing and decreasing load and the partial repetition of increasing and decreasing load. The results obtained were as follows: 1. The void ratio e was decreased according to the increase of preloading and the repe- tition of increasing and decreasing load. 2. In case of the partial repetition of increasing and decreasing load the compression index Cc was decreased with the increase of preloading and the repetition of increa- sing and decreasing load 3. The expansion rate was greatly increased with the whole repetition of increasing and decreasing load and it was inclined to be increased with the increase of preloading in case of the partial repetition. 4. The coefficient of volume compressibility were decreased according to the repetition of increasing and decreasing load 5. The secondary consolidation coefficient was decreased with the repetition of increasing and decreasing load. Especially in case of the partial repetition, the peaks of secon- dary consolidation curves could be found to move toward the vicinity of preloading.
