스마트버스정류장의 사례 조사 및 평가를 통한 유니버설디자인 적용방향 연구
박기돈 ( Park Ki Don ),고영준 ( Ko Young Jun ) 한국상품문화디자인학회 2021 상품문화디자인학연구 Vol.64 No.-
Recently, smart bus stops using smart technologies such as real-time bus usage information and smartphone charging have been installed nationwide. In the case of public transportation buses, the multifunctional convenience functions provided by smart bus stops need to be applied correctly from the perspective of universal design because they are used by various types of citizens. This study was conducted to identify problems in terms of universal design and to derive a solution direction through the analysis of precedents for smart bus stops installed at home and abroad and on-site evaluation of two smart bus stops in Gangnam-gu and Seongdong-gu, Seoul. The study found that guidance blocks to smart bus stops should be properly installed for the blind, and braille should be added to facilities such as smartphone chargers and emergency bell. Two entrances should be secured for smooth passage of general bus users by providing a waiting space for wheelchair users, and information provided through kiosks should be provided in foreign languages in addition to Korean, making it convenient for foreigners to use. It is hoped that the direction of applying Universal Design presented through this study will be applied to the smart bus stop to be installed in the future, which will help various bus users use bus stops.

유니버설디자인을 적용한 서울시 스마트버스정류장 무인정보단말기 디자인 제안
박기돈 ( Park Ki Don ),고영준 ( Ko Young Jun ) 한국상품문화디자인학회 2021 상품문화디자인학연구 Vol.66 No.-
Recently, smart bus stops that apply smart technology are being installed nationwide. Information on public transport buses and kiosks provided in them needs to be correctly applied from the perspective of universal design because it is used by various types of citizens. This study was conducted to identify the information provision method provided by smart bus stops and the universal design of kiosks by conducting service safari and customer travel maps at bus stops installed in Seoul, and to propose a kiosk design with improved universal design. Studies have shown that wheelchair users have difficulty accessing kiosks and body reach for manipulation, and visually impaired people have difficulty recognizing information that focuses on kiosks positioning and visualization. Foreigners had problems recognizing accurate information if they did not support their own language. Also, there was a difficulty in efficiently installing information providing devices in a narrow space of a smart bus stop. To solve this problem, the functions of various existing devices were integrated into one kiosk, and the monitor of the kiosk was divided into three parts to present a design that applied the functions necessary for each screen. It is expected that the design of the kiosk presented in this study will be applied to the kiosk at the smart bus stops to be installed in the future, so that various bus users can use the bus conveniently.

가열 온도에 의한 소나무와 잣나무 생엽과 생지의 연소 온도변화
김관수,장인수,박기돈 대전대학교 기초과학연구소 1995 自然科學 Vol.6 No.-
본 연구는 산불 발생시 연소대상 침엽수종인 소나무(Pinus densiflora)와 잣나무 (Plnus koraiensis)의 생엽과 생지를 가열온도에서 시료량에 따른 연소온도 변화와 연소열량의 관계를 조사한 것이다. 잣나무 시료의 함수량은 80℃ 에서 2시간이 경과될 때, 소나무 시료보다 9.91% 정도 많았으나 4 시간이 경과되면서 두 시료의 함수량은 5% 정도로 급격히 저하되어 강한 인화성 건엽으로 전환되었다. 소나무 생엽과 생지 시료의 착화는 400℃의 가영온도에서 각각 약 7분 10초와 13분 20초에 일어났으며, 발염은 각각 약 12분 20초와 15분경에 일어났다. 생엽과 생지 시료의 연소온도는 가열온도와 관계없이 각각 76℃, 106℃ 상승했다. 400℃의 가열온도에서, 소나무와 잣나무 생엽 시료의 고온 지속시간은 각각 0-07'16", 0-07'08" 였으며, 600℃에서는 각각 0-04'45", 0-02'13"였다. 따라서, 고온 지속시간은 고온일수록 짧았다. 각 가열온도에 따른 연소온도와 최고 온도의 관계는 가영온도가 낮으면 상승되는 온도는 낮았고, 높은 가열온도에서는 높은 온도가 상승했다. 생엽과 생지 시료의 전연소열량은 대체적으로 각각 1253.4㎉ (21.5%), 1290.6㎉ (14.3%) 였으며 생엽 시료가 생엽 시료보다 약 37.2 ㎉ (7.2%) 더 적었다. Present study aims at examining how the amount of sample and changes in combustible temperature of fresh branches and leaves treated with heating temperature are associated with combustible time of two coniferous trees, Pinus densiflora (D) and Pinus koraiensis (K), which are the main victims of forest fire. During the first two hours at 80℃, moisture content of K was higher than that of D by 9.9%, but after four hours, the moisture content was both lowered by 5% and turned into highly combustible leaves. At 400℃ of heating temperature, catch-fire of fresh leaves and branches of D occurred in 0-07'10" and 0-13'20", and also burning times were 0-12'20" and 0-15'03", respectively. Also, with fresh leaves (D,K), the duration of high temperature was as follows: 0-07'16", 0-07'8" at 400℃ and 0-04'45", 0-02'-13" at 600℃, respectively. With fresh leaves and branches, the maximum combustible temperatures, regardless of heating temperature, were 76℃ and 106℃. Concerning the relation between the amount of burnt fuel and maximum temperature, the more amount of the former was, the higher the latter was. The total amount of combustion-heat of fresh branches and leaves were 1253.4 kcal (21.5%) and 1290.6 kcal (14.3%), respectively. So, fresh leaves were about 37.2 kcal (7.2%) less than fresh branches.
