  • The axiomatic design principles are applied to the conceptual design of semi-submersible type mobile harbor (B1). The process of how the design of mobile harbor is elaborated, evaluated and improved from the very beginning is presented in this paper. The concept of mobile harbor is a functional harbor, which can move to a container ship anchoring out of ports in the deep water to load/unload containers on sea and transfer them to their destination ports. This floating system will innovate the maritime transport and distribution since it will greatly enhance the accessibility of super-sized container ships to existing harbors and harbors without enough infrastructures. Designing a mobile system which can perform the functions of traditional harbors on the floating system requires innovative ideas as well as rigorous validations of each sub systems. In order to enhance the chance of design success, we try to satisfy the design axioms in early stage of conceptual design. We use the zigzagging process for defining Functional Requirements (FR)-Design Parameters (DP) hierarchy due to the complexity of the system. In other words, we decomposed the complexity of the design by FR-DP hierarchy and reduced coupled design logically and systematically. This paper shows applicability of the axiomatic design principles to the field of ocean systems engineering.

  • In connection with medical care, designs have been developed by forming relationships, typically supporting Visual Communication Design, Product Design and Environment Design healthcare environment aesthetically pleasing and convenient. However, in recent designs, expertise has increased, new areas specialized are merged with various areas and academic disciplines and subdivided. In addition, due to the development of technology, the design has been continuously changing, creating a new form of model by fusing with various industries, academics and services. Recognizing the changes and developments of these designs, we are promoting research on utilization of design in medical services, we can create a new value by getting out of design that we have limitedly used in areas of traditional design I will try to know about developing into a design.

  • A multi-level overtopping wave energy converter was designed according to the large tidal range and small wave heights in China. It consists of two reservoirs with sloping walls at different levels. The reservoirs share a common outflow duct and a low-head axial turbine. The experimental study was carried out in a laboratory wave-flume to investigate the overtopping performance of the device. The depth-gauges were used to measure the variation of the water level in the reservoirs. The data was processed to derive the time-averaged overtopping discharges. It was found that the lower reservoir can store wave waters at the low water level and break the waves which try to climb up to the upper reservoir. The upper sloping angle and the opening width of the lower reservoir both have significant effects on the overtopping discharges, which can provide more information to the design and optimization of this type of device.

  • Objectives : The aim of this study was to find out some rationales for using Hominis placental extract(HPE) pharmaco-acupuncture on asthmatic patients, and to suggest an appropriate clinical research of HPE pharmaco-acupuncture on asthma. Methods : Articles regarding immunologic experiments about HPE and clinical reports about HPE-contained pharmaco-acupuncture on asthmatic patients were reviewed by on-line and off-line searching. Results and Conclusions : HPE is suggested to have several pharmacological effects on allergic diseases including asthma as well as autoimmune diseases. There are some observational studies of HPE-contained pharmaco-acupuncture on asthmatic patients. However, the designs of these studies are not sufficient to investigate the exact effect of HPE pharmaco-acupuncture on asthma. To investigate HPE pharmaco- acupuncture as a novel asthma therapy, it will be needed to perform further experiments about HPE's pharmacological mechanism on asthma and to try further advanced clinical researches such as well-designed randomized controlled trial of HPE pharmaco-acupuncture.

  • The promoter that plays a very important role in gene expression as a signal part has various binding sites for transcription factors. These binding sites are located on various parts in promoter region and have highly conserved consensus sequence patterns. This paper presents a new method for the consensus pattern search in promoter regions using genetic algorithm, which adopts the assumption of N-occurrence-per-dataset model of MEME algorithm and employs the advantage of Wataru method in determining the pattern length. Our method will be employed by genome researchers who try to predict the promoter region on anonymous DNA sequence and to find out the binding site for a specific transcription factor.

  • Purpose: The purpose of this study was to identify the relationship among stress, physical symptoms and coping styles of high school students. Methods: In this study, 356 second grade high school students (male 181, female 175) from two schools, which were located in Dae-gu city, participated in the study. Mean scores with standard deviation, T-test, ANOVA, Pearson's Correlation Coefficient were used to analyze the data. Analysis was done using the SPSS/PC program. Results: The stress level of high school students averaged 2.59 out of a possible score range between 1 and 5, and physical symptoms, 2.38. The average level for coping styles was 1.36 of a possible range between 0 and 3. The correlations between stress and physical symptoms (r=.506), between physical symptoms and coping styles (r=.304) and between stress and coping styles (r=.363) were all significant. Conclusions: To guide the high school health program, we must try to understand the traits of the students and make efforts to identify personal and concrete difficulties in coping. Therefore it is necessary to use a stress care program to systematically improve their health.

  • Since the previous cut-and-try design algorithm requires much cost and time, the automated design technique with the CFD and optimum design algorithm has recently been concerned. In this work, the Navier-Stokes equation was solved to gain more detailed viscous flow information of cascade with rotor-stator interactions. The H-grid embedded by O-grid was generated to obtain more accurate solution by eliminating the branch cut of H-grid near airfoil surface. To handle the relative motion of the rotor to the stationary stator, the sliding multiblock method was applied and the cubic-spline interpolation was used on the block interface boundary. To validate present procedure, the time-averaged aerodynamic loads were compared with experimeatal data. A good agreement was obtained. The Modified Method of Feasible Direction (MMFD) was used to carry out the sensitivity analysis of the change of aerodynamic performance by the changes of the cascade geometry. The present optimization of the cascade gave a dramatic reduction of the drag while the lift maintains at the value within the user-specified tolerance.

  • This research consists of (1) building (or molding) the Dynamics Simulation Model on Return Policy mainly used in publications, phonographs, and computer industry; which are seen used in supply chain contract known as effective control mechanism under the varied supply chain situations, and (2) analyzing the effects that return rates and seller's contract parameters have in the outcome of the model and (3) observing how the effectiveness of Return Policy changes under such circumstances where the buyer's sales ability and the seller's risk inclination are taken into account. Thus, the main purpose of this research lies in analyzing what exactly are the effects (and or outcome) that sales ability and risk inclination have in Return Policy, and additionally by conducting comprehensive research on Supply Chain Policy Dynamics Simulation Model, we will try to prove that not only the Systems Dynamics approach is highly contributive in supply chain management but also that it will serve as a foothold in future research. As a result of the research, supply chain achievement level turned out to be high when Return Policy is enforced, and the achievement level was even higher when seller's sales ability was taken into consideration along with the Return Policy. On the other hand, the achievement level decreased when the seller had risk aversive tendencies.
