Since the apple company adopted the desktop-office metaphor in Macintosh, the metaphoric interface has been used generally in multimedia products or services, on which user-friendly knowledge, conception, and images are represented metaphorically. Although the metaphor can be employed as one of ways to identify the essence or pattern of information, a theoretical framework on its relation with the user interface is not fully established. In this study, the user interface considered as a core of multimedia design was discussed, and the form of the graphic metaphor was investigated. The seven forms of the graphical metaphor presented herein would be applied as one of approaches to the user interface in relevant researches.

Steroid $9{\alpha}$.-hydroxylase is a key enzyme system in steroid nucleus degradation in company with ${\Delta}$-dehydrogenase. To examine $9{\alpha}$-hydroxylase activity during microbial transformation of steroids, 9(11)-dehydro-$17{\alpha}$-methyl-testosterone was adopted as a stable substrate for preventing the rupture of steroid nucleus. Using Nocardia restrictus ATCC 14887 capable of introducing a $9{\alpha}$-hydroxyl group into steroids, $9{\alpha}$,$11{\alpha}$-oxido-$17{\beta}$-hydroxy-$17{\alpha}$-methyl-4-androstene-3-one and $9{\alpha}$-hydroxyl group into steroids,$9{\alpha}$,$11{\alpha}$-oxido-$17{\beta}$-hydroxy-$17{\alpha}$-methyl-1,4-androstadiene-3- one were obtained. These microbiologically transformed products could be used as reference compounds in the enzyme assay.

Conjoined twins are rare, and each set of conjoined twins has a unique conjoined anatomy. It is necessary to perform separation to increase the chance of patient survival. Tissue expansion is an advanced technique for providing sufficient soft tissue and skin for wound closure. We report the successful application of rapid tissue expansion in 10-month-old xipho-omphalopagus conjoined twins in Vietnam. A tissue expander was placed on the anterior body between the sternum and umbilicus with a baseline of 70 mL sterile saline (0.9% NaCl). The first injection into the tissue expander began on the 6th day after expander insertion, and injections continued every 2 days with approximately 30-70 mL per injection according to the expansion of the skin. The expander reached 335 mL after six injections and within 10 days. In order to prepare for surgical separation, expansion was completed on the 15th day after insertion. The expanded skin area was estimated to be 180 cm², which was sufficient to cover both patients' skin deficiencies. The twins presented for surgical separation 6 days following the completion of tissue expansion. Both babies were discharged in good health 1 month after separation.

The objective of the present research is to develop the novel multi-compaction technology to produce hybrid structure in powder metallurgy (P/M) components using dissimilar Fe-based alloys. Two distinct powder alloys with different compositions were are used in this study: Fe-Cr-Mo-C pre-alloyed powder for high strength and Fe-Cu-C mixed powder for enhanced machinability and lower material cost. Initially, Fe-Cu-C was pre-compacted using a bar-shaped die with lower compaction pressure. The green compact of Fe-Cu-C alloy was inserted into a die residing a half of the die, and another half of the die was filled with the Fe-Cr-Mo-C powder. Then they subsequently underwent re-compaction with higher pressure. The final compact was sintered at 1120℃ for 60 min. In order to determine the mechanical behavior, transverse rupture strength (TRS) and Vickers hardness of sintered materials were measured and correlated with density variations. The microstructure was characterized using optical microscope and scanning electron microscope to investigate the interfacial characteristics between dissimilar P/M alloys.

In this study, the effect of the coiling temperature on the tensile properties of API X70 linepipe steel plates is investigated in terms of the microstructure and related anisotropy. Two coiling temperatures are selected to control the microstructure and tensile properties. The API X70 linepipe steels consist mostly of ferritic microstructures such as polygonal ferrite, acicular ferrite, granular bainite, and pearlite irrespective of the coiling temperature. In order to evaluate the anisotropy in the tensile properties, tensile tests in various directions, in this case 0° (rolling direction), 30°, 45° (diagonal direction), 60°, and 90° (transverse direction) are conducted. As the higher coiling temperature, the larger amount of pearlite is formed, resulting in higher strength and better deformability. The steel has higher ductility and lower strength in the rolling direction than in the transverse direction due to the development of γ-fiber, particularly the {111}<112> texture.

Nowadays most business organizations wish to hire competent people who can do their own jobs efficiently right after their employment. The primary goal of this study is to focus on how we can train undergraduate students in academia-industry collaboration to satisfy this requirement. By making use of the funding from the Ministry of Education & Human Resources Development to support academia-industry collaboration program, we established an intramural company, Hankyong Design Company, and set up several studio courses for junior and senior students. To develop these courses efficiently for the first semester of 2005, studied both intramural and extramural environments of academia-industry collaboration and searched for good examples of them. Based on this investigation, I made some assumptions that how we can perform the academia-industry collaboration program for undergraduate students successfully. I chose several design tasks related to digital communications, and appointed WisePost Inc., an Internet communication service company for MSN Messenger, to be a collaborator. We made the 'Interactive Design' studio courses together and applied the courses to 20 juniors. At the end of the semester, we evaluated the works of the students, and selected and commercialized some excellent items among them. During the course work, I realized the fact that education programs in academia-industry collaboration is feasible for undergraduate students majoring in design. I understanded the overall merits and demerits of conventional studio and academia-industry collaboration courses. In addition, the results from the present study suggest that the role of professor in academia-industry collaboration program would be quite different from conventional studio courses.

As for the public, it is hard to understand semiotics because of the scope of an enormous semiotics education. This study is making semiotics of Charles Sanders Peirce the subject. I thought that utilization can hold his semiotics study in a visual design field. First of all, this study considered design related papers related to the existing semiotics again and study found an error of the existing semiotics study and understanding did category concept with re-definition about semiotics of Peirce. Explained a symbol mark through understanding of semiotics of Peirce. This study was able to get the following conclusion through these results. 1) A symbol mark means one product, sonics, company oneself with a custom. Therefore, it is a rule symbol in the Representation side. 2) A symbol mark symbolizes an object with one symbol, so a symbol mark is a symbol in an object. 3) Because a symbol mark exists through a social rule, in semiotics definition of Peirce, this must become understanding with a Argument symbol. 4) A symbol mark is what a company or an organization field used from the past, and the public are recognizing this how. Therefore, it works as fact a company attaches a symbol mark to own product, and to show the public a symbol mark. A symbol mark is Dicent Sign in Interpretant. A rule and understanding about a lot of types which have various mutual relation, Peirce classification and understanding of a symbol mark tells to demand is holding that understanding a type of semiotics with the concept that is not an image to us.
