Fireworks display is called as younwha in korean, pokjuk in chinese, hanabi in japanese and fireworks display in English. Fireworks is a kind of art calling as engineering art program that presents its artistic sense by making up light, sound, heat, form, smoke, smoke screen, time delay and kinetic energy etc. which are made by combustion and deflagrations of explosives. Korea's fireworks skill is world class. In 1980s, we already developed the skills. After 2010 year, It would develop as Nano-biotechnology considering its environmental safety passing by 1990s' grow fully step. After pleasant fireworks, it requires a environmental pollution control measure, ability of emergency state control, management of storing place, a blind shell and waste disposal and citizenship elevation etc. This paper indicated around fireworks the present conditions, environmental pollution buzz, direction of development and plan.

This study proposes the use of firework shapes to design fashion accessories in the judgment that they are appropriate for the expression of creative images in consideration of the display of fireworks as a kind of entertainment and a festive symbol. This study promotes the sustainable application of firework shapes to develop the designs of fashion culture items that feature a distinctive personality and uniqueness. In this present study, the proposed fashion accessory design was intended to create an entertaining new atmosphere that uses an Organic Light Emitting Diode (OLED) that draws attention as a futuristic display. In terms of methodology, a literature review of firework shapes and OLED was conducted; in addition, Adobe Illustrator CS2 and Adobe Photoshop CS2 were used to develop six different standard motive designs with formative design elements represented by a variety of firework shapes. Each of the six motifs was further expanded with different color combinations. Rich images are produced with the use of pink, blue, purple, green, yellow, orange, and red, in conjunction with various OLED effects to express the three-dimensional images of fireworks. The motifs are applied to three types of items: bags, bracelets, and necklaces. For the video images, evening and tote bags, pendants, and bangles were used. Shifting images and lights should produce unique images as well as satisfy the consumer desire for entertainment. The Adobe Image Ready software was used to present the motive of fireworks applied to the design of fashion accessories in video images but not in still-cut images due to physical constraints of this paper.

불꽃놀이는 한국명 연화(煙火), 중국명 폭죽(爆竹), 일본명 하나비(花火), 영어명 파이어웍스 디스플레이(Fireworks display) 표기되며 화약류를 연소 폭발시켜서 빛, 소리, 형태, 연기, 연막, 시간지연, 운동에너지 등을 조합하여 예술적인 감각을 연출시키는 공학으로써 공예술학으로 불랴는 일종의 예술작품이다. 우리나라의 연화기술은 세계적이다. 1980년대에 개발이 완료되었고, 1990년대에 완숙단계흘 거쳐 향후 2010년 이후에는 환경안전을 고려한 최첨단 나노 생명공학으로 발전하여야 할 것이다. 즐거운 불꽃축제 후에 환경오염방지 대책과 비상체제 운영능력, 저장소관리, 불발탄 및 폐기물처리, 시민의식 향상 등이 더욱 요망된다. 본 논문은 올해 제4회를 맞는 부산불꽃축제를 중심으로 현황 및 발전방향과 개선안을 제시하였다.

Although precision blasting constructions are increased by explosive industry, the studies on the history of explosive are small in number. In this study, we tried to find the origin of explosive and make it, which we found, be storization to develop the technology of modern explosive and blasting. Also, we presented the methods that apply storytelling about the explosive technology to construction project.

The purpose of this study was to investigate mathematics teaching of an elementary school teacher and to understand the meaning of it. This study was a qualitative case study using by analyzing metaphors. The notion of metaphors was newly set up. Traditionally, it had been regarded as a mere tool for better understanding, but it was recognized as the primary source of all of our concept(Sfard, 1998). The subject of this case study was a researcher 'I' and also an elementary school teacher. The three selves named Mee1, Mee2, Mee3, respectively. Mee1 was the 'I' who developed the 4th graders' activities on mathematical patterns in 1996 and wrote mathematics textbook for the 4th graders in 1998-1999. Mee2 was the 'I' who taught mathematical patterns to her students in 2002. Mee3 was the 'I' who criticized the teaching of Mee2 in 2005. [ADVENTURE], [HIDE-AND-SEEK], and [FIREWORKS DISPLAY] were deter-mined to be key metaphors of mathematics teaching. [ADVENTURE] of Mee] was focused on profound understanding of mathematics, [HIDE-AND-SEEK] of Mee2 on construction of mathematics, and [FIRE-WORKS DISPLAY] of Mee3 on making meaning and participating in communities. Studies of metaphors give us the power of understanding mathematics teaching and also generate it. And viewing mathematics teaching via metaphors makes teaching studies open to new ways.
