The purpose of this study is to survey what strategy BACHE, a bathtub manufacturing company, chooses to implement knowledge management. Generally speaking, the success factors of this case company is follow-up management. The first factor is to use linguistic metaphors for employees to understand difficult knowledge management terms easily. The second one is that CEO tries to set and lead pro-knowledge management corporate culture. The third one is based on the CKO's competence to read business circumstances and apply the theory of knowledge management to the workplace. The fourth one has something to do with a way of knowledge creation, for example, a suggestion system and QC circle. The fifth one depends upon CKO's mission to share knowledge invented from his own company's with the rivals and large companies which order bathtubs so that overall bathtub industry can upgrade knowledge management.

일정 경사 해저면을 갖는 해안에 입사한 파가 천수변형을 거치고 쇄파하는 과정에서 발생하는 라디에이션 응력 및 평균수위 변화를 다루었다. 일반적으로 선형파동 이론에 의해 산정된 라디에이션 응력은 쇄파대내 및 그 부근에서 과대 평가되는데, 이것이 평균수위 변동의 계산치와 실험치와의 불일치의 원인이 된다. 본 연구에서는 Svendsen(1984)이 제안한 라디에이션 응력을 수정해서, 수심의 함수로 표시하고, 계산결과를 선형이론, 쇄파의 성분파고 스펙트럼에 기초한 Sawaragi(19梨) 방법 및 기왕의 실험데이타와 비교하였다. 수정된 Svendsen의 방법은 실험치와 비교적 양호한 일치를 보여 주었다.

The aims of the study are first, in other to meet the demand for a new product design process, to review the prototype theory and to find out the conceptual structure of product aesthetics, which is another properly thought to be as important as the typical pattern in an effort to patch up the theory second to help designers overcome the limits of idea generation and create consumer oriented designs with a high success rate by setting up a new product design process that is established through the application of the aesthetically influential factor 'proportion'based on the preceeding studies that tested product aesthetics measuring devices. In other words, this study tries to find out product categories, making use of the prototype theory to introduce an ideal proportion for product design, recognizing the importance of proportion by conducting product pattern analysis: to create a differentiated method that can product consumer oriented designs, even if it only manipulate proportion and to establish a new design process that can systematically explain the methodology for various form generation that applies proportion. This study reviews the theoretical aspects of concepts pertaining to the above … and, based on them, empirically tests them by patting to use the programs, for proportion manipulation. This study was conducted in the following way: To begin with, this study takes out proportion out of some aesthetically influential factors that has a great impact on the way consumers prefer certain product designs and tries to see how proportion affects the consumer preference when consumers select a product. In addition, we could analyze the difference between the ideal proportion that consumers prefer and the traditional golden proportion produced through theoretical studies. The correlations between preferred proportion and ideal proportion, and preferred proportion and golden proportion could be shown. In order that we may create form variations through more detailed proportion manipulation on the basis of the ideal proportion verified as preferable, we again applied the proportion factor to the process utilizing PDS(proportion Distortion System). In the way the restraint of form generation could be pursued. All in all, this study makes an attempt to set up a design process to create new product forms through the application of Proportion.

Some applications require structural health monitoring in inaccessible components. This paper presents a technique useful for Structural Health Monitoring of double wall structures, such as double wall steam pipes and double wall pressure vessels separated from an ultrasonic transducer by three layers. Detection has been demonstrated at distances in excess of one meter for a fixed transducer. The case presented here is for one of the layers, the middle layer, being a fluid. For certain transducer configurations the wave propagating in the fluid is a wave with low velocity and attenuation. The paper presents a model based on wave theory and finite element simulation; the experimental set-up and observations, and comparison between theory and experiment. The results provide a description of the technique, understanding of the phenomenon and its possible applications in Structural Health Monitoring.

This study has two aims. one is to devide the ideology of reference service into three groups such as conservative, moderative, and progressive theories, and then investigate the validity of each theory as well as any problems to be suggested. The other is to establish appropriate standards of reference service according to the types of libraries and users, based on the analysis of such theories. Each theory has its own merits and demerits. Accordingly, it seems to be difficult to apply uniformly and theory into users who have different types of question and educational levels. And also it is difficult to apply into various libraries which have different aims of establishment, characteristics, and the users of each library. Consequently, it is suggested to set up a norm of reference service according to the types of libraries and users respectively. The conservative theory is applicable to small and medium sized public libraries, school libraries, and college and university libraries of which the users are mainly students and citizens. The progressive theory is desirable for special and academic libraries as well as large public libraries where the users are mainly specialists. and scholars.

This study aims to suggest a Biophilic classroom design of high school to obtain attention restoration for students. The learning space for youth in the modern society is composed of dry artificial structures. This space is considered to be a space that can not relieve stress caused by learning. "The Attention Restoration Theory" is divided into "Directed Attention" of humans, which is the cause of fatigue and stress, and "Involuntary Attention" as a solution to it. "Involuntary Attention" takes place in a rest state and helps the brain recover when exposed to nature. And the core of "Biophilic-Design Theory" is that humans can recover physical and mental conditions when exposed to nature. The purpose of this study is to apply "The Biophilic-Design Theory" that emphasizes the importance of exposure to nature to the educational space and plan the space where the 'Attention Restoration' can be achieved. The research method is as follows. First, we review previous studies related to "The Biophilic-Design Theory" and "The Attention Restoration Theory". Second, we analyze the application examples of "The Biophilic-Design Theory" and "The Attention Restoration Theory" in domestic and foreign educational spaces. Third, the concept of educational space is set up based on the elements derived from previous studies. Finally, we propose the planning direction of classroom design based on Biophilic-Design. The following conclusions were drawn. First, The creation of the education space to restore the learner's attention requires a visual space plan that utilizes natural elements such as natural light, artificial light, plants, and natural materials that can directly experience nature. Second, the direction in which students in the classroom can be "The Attention Restoration Theory" should consider the use of indirect natural elements that bring the surrounding natural landscape into the interior. This study will be used as the baseline data for the spatial design and planning of education facilities based on Biophilic-Design.

The purposes of the study were to investigate the participation of artists in paper circuit computing learning and to conduct an in-depth study on the formation and development of practical knowledge. To do this, we selected as research participants six artists who participated in the learning program of an art museum, and used various methods such as pre-open questionnaires, participation observation, and individual interviews to collect data. The collected data were analyzed based on community of practice theory. Results showed that the artists participated in the learning based on a desire to use new technology or find a new work production method for interacting with their audiences. In addition, the artists actively formed practical knowledge in the curriculum and tried to apply paper circuit computing to their works. To continuously develop the research, participants formed a study group or set up a practical goal through planned exhibitions. The results of this study can provide implications for practical approaches to, and utilization of, paper circuit computing.

Residual Deformation Analysis(RDA) is a new method for ratings of the continuous bridges. The RDA makes it possible to expand the inelastic steel girder bridge design method set forth in the American Association of State Highway Officals'(AASHTO) Guide Specifications for Alternate Load Factor Design Procedures for Steel Beam Bridges Using Braced Compact Sections(1986) into an inelastic rating method. It is a method to assess the residual moments and deformations that are set up in a beam that has been loaded into the post-elastic range This method combines classical elastic conjugate beam theory with linear moment-rotation relationships for midspan inelastic positive moment. The limit state is inelastic serviceability limit. which is defined as the ratio of the span to midspan inelastic deflection(C=L/D).
