  • This study was intended to answer the question, 'What kinds of effects will be aroused by experiential learning for environment based on living area?'. Experiential learning for environment was operated to 17 elementary school students in 4th grade in Kyeong-san city. The results were drawn analyzing the mind map for the changes of environmental consciousness before and after learning, and they are as below. First, it had an effect to change the meaning association of the relationship between 'river and me'. Meaning association was 'river-a thing' before experiential learning, but it was developed as 'river-a thing-me' after learning. This means that students expanded understanding of the world that they were belonging and self-spatialization was promoted. The expansion of meaning association would be a start point and a method to promote their segmentation for each student. Second, students could self-directly modify misconception and preconception after experiential learning. It showed that students could find meanings in the world that they were belonging by experiential learning for environment, and misconception obtained by concept learning without actual situation could be revised through the truth recognition in meanings, and student could see what things displayed. Therefore preconception would be corrected. Of course, everything would not be completed by just one time of experiential learning, and consistent experience learning should be operated. Third, experiential learning promoted the change of sensitivity. Students had shallow sensitivity, which appeared in the relation with things, since having learned only inside of class without a direct observation. However their sensitivity could be increased by experiencing specific things. Fourth, there was the change of classification recognition. Students found properties of things with a direct observation. It raised their ability to classify things, and to understand an individual thing in 'a class'.

  • This study analyzed the characteristics of vegan fashion produced by H&M and ZARA with respect to materials, design, development, production, and marketing to create social value. The results of this study are significant because they can be used as a reference to develop a vegan fashion market. Regarding the research method, this study assessed the concept and status of veganism through a literature review and examined vegan fashion case studies by analyzing official websites and media content. The study's scope covers the period from 2005, when H&M was the first SPA brand to create a vegan product line, until 2019. The characteristics of Global SPA's vegan fashion were as follows. Regarding materials, alternative materials were developed and an expanded use of organic materials was implemented. Regarding design, development was achieved through design collaboration and upcycling. In terms of production, an animal welfare policy was adopted and a sustainable supply chain was established. Marketing employed a campaign aimed at encouraging increased consumer participation. The findings regarding the social value of H&M and Zara's vegan fashion were as follows. First, a cyclical economy was realized through circular recycling in the entire process of resource selection, production, and waste disposal. Second, because product consumption indicated the importance of ethical consumption and sustainable consumer participation, corporate financial activities were created based on shared values to accomplish the social outcome. Third, collaborations with luxury brands or vegan fashion designers built a collaborative ecosystem in which vegan fashions were released and consumer participation campaigns were implemented.

  • In this study, we described a simple and facile method to generate uniform microwells poly(dimethyl siloxane) (PDMS) microstamps through micro-molding for efficient, rapid and reliable cell patterning of adipocyte differentiation. In contrast to the conventional methods, the microstamp technologies are low expensive, non-toxic, and using a small amount of solution. Recently, Orlistat known as tetrahydrolipstatin is a prescription drug designed to treat obesity which is used to aid in weight loss and help to reduce overweight obesity. Here, 3T3-L1 cells were treated under various concentration manners of Orlistat $0.2{\mu}M{\sim}5.0{\mu}M$. and it was confirmed maximum 26.5% inhibition activity compared to control. Thus, we elucidated this platform can be used for the real-time analyzing of cell proliferation, adipocyte differentiation for evaluation of anti-obesity agents on cell chip. Furthermore, we except that this platform technology designed here might be readily be expanded to discover a wider variety of anti-obesity agents.

  • This study started to deduce a permeability relationship that can consider the geometric features of various porous media under different flow regimes. With reference to the previous works of Kozeny and Carman, the conventional Darcy-Weisbach relation (Darcy's friction flow equation) was reviewed and expanded for porous flow analysis. Based on the capillary model, this relation was transformed to the friction equivalent permeability (FEP) definition. The validity of the FEP definition was confirmed by means of comparison with the Kozeny-Carman equation. Hereby, it was shown that the FEP definition is the generalized form of the Kozeny-Carman equation, which is confined to laminar flow through a circular capillary. In conclusion, the FEP definition as a new permeability estimation method was successfully developed by expanding the Darcy-Weisbach relation for porous flow analyses.

  • The expanded application of digital controls has raised the issue of cyber security for nuclear facilities. To cope with this, the cyber security technical standard RS-015 for Korean nuclear facilities requires nuclear system developers to apply security functions, analyze known vulnerabilities, and test and evaluate security functions. This requires the development of procedures and methods for testing the suitability of security functions in accordance with the nuclear cyber security technical standards. This study derived the security requirements required at the device level by classifying the details of the technical, operational and administrative security controls of RS-015 and developed procedures and methods to test whether the security functions implemented in the device meet the security requirements. This paper describes the process for developing security function compliance test procedures and methods and presents the developed test cases.

  • The esthetics of 'grotesque' and its entertaining values have many things in common with the characteristics and properties of animation as a medium of expression. The ways to express grotesque images in animation have expanded its realm of expression with the development of modern image digitalization technologies. The grotesque images that were expressed by the combination of photographs and animations and objet animations have been developing its disharmony in a more realistic manner with full 3D animation technology and realistic motions of virtual characters with motion capture. The subject matter also has become more diverse with the advance of modern scientific civilization. An example is the appearance of Cyborg(cybernetic+organism) characters and the grotesque images in the modern times mainly start to appear in animations dealing with the isolation of human beings among its characteristics. Also, the changes of the expression methods of grotesque images along with the development of visual technology development in the future will transform its methodological forms by changing its expression methods to VR forms and interactive visuals. Thus it is expected that the grotesque images and characteristics will change into a visual genre which emphasizes dehumanization.

  • In this study a 3-component rotating balance, which is designed to measure the thrust (Fz) and two moment components (Mx, My) simultaneously for a rotor test jig, is designed and its performance is validated experimentally. The low voltage signal from the strain gages mounted on the balance is amplified with a rotating amplifier, which is then fed through a slip-ring unit into the data acquisition system. In order to validate the accuracy of the calibration matrix obtained from a static calibration test, an additional reaction type balance is used to measure the thrust from a model rotor simultaneously, and shows very good result. Finally, the expanded uncertainty value, which is obtained from ISO method is estimated to be $2.82\times10^{-1}$, and the balance turns out to be reliable.
