  • The speed of the reformation of the Korean engineering and science education systems is very slow compared with the fast change of the society. Current society requires colleges to raise high quality gold color engineers, who can feed tens of thousands people, however current education system cannot fulfill the requirement. So we need a novel education system to adapt the fast change of the society. In this study, we analyzed the difference of the education quality between supplies and demands, and based on the analysis, we suggested a new continuous quality improving system. We also collected current data on the student capability of Korean engineering freshmen and surveyed on the required vocational basic skills. Finally we suggested some programs with that the government could support improving the quality of engineering and science college students.

  • In this study, we synthesize tungsten oxide thin films by electrodeposition and characterize their electrochromic properties. Depending on the deposition modes, compact and porous tungsten oxide films are fabricated on a transparent indium tin oxide (ITO) substrate. The morphology and crystal structure of the electrodeposited tungsten oxide thin films are investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). X-ray photoelectron spectroscopy is employed to verify the chemical composition and the oxidation state of the films. Compared to the compact tungsten oxides, the porous films show superior electrochemical activities with higher reversibility during electrochemical reactions. Furthermore, they exhibit very high color contrast (97.0%) and switching speed (3.1 and 3.2 s). The outstanding electrochromic performances of the porous tungsten oxide thin films are mainly attributed to the porous structure, which facilitates ion intercalation/deintercalation during electrochemical reactions.

  • This study aimed to assess the satisfaction levels of adolescents with beauty programs, investigate the factors influencing them, and present foundational insights for designing cosmetics and beauty education initiatives tailored to adolescents. Specifically focusing on the "Safety and Use Education for Youth Cosmetics" program implemented in Gwangju Metropolitan City, it examined the satisfaction of participants, including students, instructors, and school teachers involved in the education. The study was based on action research, a qualitative methodology. The conclusions are as follows: First, participants gained knowledge and information encompassing various aspects of cosmetics, such as types, expiration dates and usage span, face wash and skin types, shampooing methods, scalp care, role and significance of sunscreen, skin trouble management, and identification of skin type, through cosmetic education programs. Second, participants learned about techniques such as eyebrow trimming, eyebrow shape correction, facial contour correction, skin blush supplementation, color makeup, personal color, and tattooing. Third, there is an urgent need to develop different educational teaching resources suitable for implementation across elementary, middle, and high schools. Fourth, it is necessary to cultivate higher-quality instructors in this digital age. Fifth, it is crucial to explore new methods of delivering beauty education to adolescents. We hope the insights gleaned from this study will serve as useful foundational data, albeit modest, fostering new beauty trends amidst the challenging landscape of youth education.

  • Black-out Game(Lightout, Merlin Game, ${\sigma}$+Game) is an interesting game on the chessboard, when you click a button with black or white color, it changes color of itself and other buttons who shares edges. With this rule, we win the game when we have a chessboard with all same color after we click some of the buttons of it. Pretty much of research has been made on founding the winnable strategy for this type of game. In this paper, we first introduce a history of mathematical modeling on this game. Then we develop an algorithm to offer a winnable blackout game of any size. Our tools also show our new algorithm works. Finally, we show how we can use this game in mathematics education.

  • There are five contexts of division algorithm of fractions such as measurement division, determination of a unit rate, reduction of the quantities in the same measure, division as the inverse of multiplication and analogy with multiplication algorithm of fractions. The division algorithm, however, should be taught by 'dividing by using reciprocals' via 'measurement division' because dividing a fraction by a fraction results in 'multiplying the dividend by the reciprocal of the divisor'. If a fraction is divided by a large fraction, then we can teach the division algorithm of fractions by analogy with 'dividing by using reciprocals'. To achieve the teaching-learning methods above in elementary school, it is essential for children to use the maniplatives. As Piaget has suggested, Cuisenaire color rods is the most efficient maniplative for teaching fractions. The instruction, therefore, of division algorithm of fractions should be focused on 'dividing by using reciprocals' via 'measurement division' using Cuisenaire color rods through analogy if necessary.

  • This analysis of the educational facility planning is based on the various career, with historical backgrounds from white color, blue color to steel color, idea color, related to the planning of educational curriculum for all levels (from K-12 to higher education). The results of the analysis show that an institution for the research & development of educational facilities through the researchers and practioners occupied with architectural planning, designing and with educational curriculum planning, designing of the educational environments, is timely needed. It is fortunate that function of such institute can be carried out by Korean Educational Facility Institution which enables to research and develop educational facility in collaborative with architects and educators together. CEFPI research and development findings about educational facilities can be applied to our research and development, for the various career of our future students, with the various educational plannings.

  • This study aims to compare the properties of natural dye stuffs, such as color, dyeability, fastness, and marketability, to analyze the differences noted by expert groups regarding the properties of the stuffs, and to make a positioning of the stuffs. A survey of experts in academia, business, and the art of natural dyeing was conducted, with an evaluation of 23 types of the stuff's properties. There is a correlation between the properties of the stuffs, and evaluating dye stuffs differs according to the group to which it belongs. X-axis relates to color and Y-axis refers to fastness in the positioning of the stuff. There are different relationships between properties according to their group. Color is significantly associated with marketability in art experts however, fastness is closely connected with marketability in business. The stuffs can be divided into five clusters. Cluster I includes indigo and persimmon, and is marked by excellent color, dyeability, fastness, and marketability, Cluster II contains safflower and sappan wood, which are excellent colors, yet suffer from low marketability on account of their medium to low fastness. Cluster III includes red, purple, and brown dyes, and onion and rhubarb, and has medium properties. Cluster IV is mugwort and yellow dyes, except onion and rhubarb, and features low properties. Cluster V is loess, featuring medium color and low fastness.

  • The purpose of this study was to identify the analysis of men's wear color preference between Korean and Chinese college women. The experimental materials developed for this study were a set of stimulus and response scales. The 24 color pictures and 5-point scales were used for evaluation of preference. Data were obtained from 120 Korean college women living in Kyeongnam, Korea and 120 Chinese college women living in Shandog, China on October and November 2010. For data analysis, ANOVA and Duncan-test were used by using SPSS program. Results of this study were as follows. Korean and Chinese college women, shirts hue, tie hue, and shirts/tie tone showed an independent effect on men's wear color preference. Interaction effects of Korean and Chinese college women and shirts hue, Korean and Chinese college women and tie hue, suit hue and shirts hue, shirts hue and shirts/tie tone, and tie hue and shirts/tie tone were found. These results suggested that men's wear color preference can be affected by Korean and Chinese college women, suit hue, shirts hue, tie hue, and shirts/tie tone.
