  • In current complex nature of management with task-structures, a method to reach the enterprise's informationalization success is not common. To satisfy these various requirement, improving the usability of information technology (IT) is a key factor which defining the level of organizational requirement first. Imposing an IT-solution which has excess service of the organization's previous task-environment, procedure and scope is not effective to SME-level unit, which unit could not have a formal organization structure and task structure. SME level informationalization will be success if each function realizes easier on the task-employee's viewpoint. Achieving this objective, a solution provider or department must reflect their work characteristics of nature which has least level of work performing resistance. It is most useful system for SME level unit, if a provider develops single programs which based on task activities, and each program can configure network-linking.

  • The purpose of this study was to develop a program for the history of science and technology in order for the technical high school students to understand the nature of science (NOS). The program was composed of the six topics based on the textbooks such as convergence science and physics I, and was taught to 290 10th graders at a technical high school located in the metropolitan area. The questionnaire about NOS was asked the students before and after the instruction, so as to investigate the effect of the program on improving their understandings of NOS. The analysis followed t-test and ANOVA using SPSS 23.0 for Windows program. The questionnaire based on the conceptual framework of the four themes of the NOS (Lee, 2014). The research findings were as follows. First, the program was effective in improving their understanding of NOS since the t-test result was significant statistically for the overall domains of NOS (p<.01). Second, there was no significant gender differences in the understanding of NOS among technical high school students (p<.05), neither did their majors (p<.05). Third, all domains in NOS were statistically correlated (p<.01), and in a particular, each domain was consistently correlated with the aspect of the nature of the interactions among science, technology, and society. Hence, the further studies should be conducted to examine how the history of science and technology effects the understanding of the NOS and how the domains in NOS affected each other.

  • This study reflects the aim of analyzing the fashion design connection with ecology. Ecology has been linked to human life through its changing relations with environment. In order to recover eco-system ecology-nature oriented methodology and technology oriented approach will suffice. On the modern design field Green design Recycling and Green marketing resulted in increasing rates of environment-friendly production and an effort to deliver environment-friendly corporate image. Based on above research ecological image on fashion design during the year 1990 to 1995 represents the following conclusion. In the fashion design field natural image primitive image nature -harmonious image material-recyling image culture-recycling image are proposed. In the technology field clean image and high-tech image are proposed. In the marketing field happy image harmonious image serious image and realistic image are proposed.

  • In this paper, we try to explore the nature of open source software development process. The process involves peculiar characteristics which seem to defy the traditional economic reasoning for technology policy. Based upon the comparative case study of open source software development process with the two innovation processes adopted from literature on economic history, we argue that technology policy should strike the balance between provision of innovation incentives and voluntary disclosure of information.

  • This study is to observe the meaning, aesthetic formative nature of the human body which has been not only a main issue and discussion object but also socially, culturally connected with clothing by contemplating it in the respect of the trend of art. Additionally, a work of contemplation about human body introduced to fashion design was analyzed to renew the meaning and value of the formative art inside the human body. The way and scope of this study is to contemplate the concept and meaning of human body, based on the documentary records such as art history and clothing history in the West society as a main theme. The results of the analysis were as follows: In the first place, the formative characteristics shown in the modem arts expressing the human body since 1990 which are cubism, futurism, metaphysical painting, dadaism, surrealism, pop art, happening, feminism, body art, and technology art are distortion, exaggeration and dismantling. Second, the aesthetic formative nature and meaning in the human body appear to be different according to the standard of ideal beauty of human body when we examine the expression of it from the aspect of art-history and the meaning of human body implied in it. Besides, human body is being used as a messenger which delivers the message of modem artist to other people. So the changed meaning of human body has affected the clothing and made it possible to manufacture and form new styles of clothing that have never been before. In conclusion, the human body in the modem era plays an important role as a brand-new formative medium of communication in the human society and contributes to the development which applies the aesthetic formative nature of the human body to fashion design.

  • The structure of the human ear is divided into the outer ear, the middle ear, and the inner ear. The inner ear includes the cochlea that plays a very important role in hearing. Recently, the development of an artificial cochlear device for the hearing impaired with cochlear damage has been actively researched. Research has been carried out on the biomimetic piezoelectric thin film ABM (Artificial Basilar Membrane) in particular. In an effort to improve the frequency separation performance of the existing piezoelectric thin film ABM, this paper presents the design, fabrication, and characterization of the production and performance of a partially etched-type ABM material. $O_2$ plasma etching equipment was used to partially etch a piezoelectric thin film ABM to make it more flexible. The mechanical-behavior characterization of the manufactured partially etched-type ABM showed that the overall separation frequency range shifted to a lower frequency range more suitable for audible frequency bandwidths and it displayed an improved frequency separation performance. In addition, the maximum magnitude of the vibration displacement at the first local resonant frequency was enhanced by three times from 38 nm to 112 nm. It is expected that the newly designed, partially etched-type ABM will improve the issue of cross-talk between nearby electrodes and that the manufactured partially etched-type ABM will be utilized for next-generation ABM research.

  • In the previous study, we reported the antioxidative activity, antiaging activity, antibacterial activity and moisturizing effect of cream containing Persicaria hydropiper L. extract. In this study, the components of Persicaria hydropiper L. extract were analyzed by TLC and HPLC. Aglycone fractions obtained from the deglycosylation reaction of ethyl acetate fraction among the Persicaria hydropiper L. extract, showed 2 bands and 2 peaks in TLC and HPLC experiments, respectively. Two components were identified as quercetin and kaempferol. TLC chromatogram of ethyl acetate fraction of Persicaria hydropiper L. extract revealed 6 bands and HPLC chromatogram showed 7 peaks, which were identified as quercetin, hyperin, isoquercitrin, quercitrin, kaempferol. In conclusion, with the antioxidative activity, antiaging activity, antibacterial activity and moisturizing effect reported previously, component analysis of Persicaria hydropiper L. extracts could be applicable to new cosmeceuticals.
