YoungDo bridge is the first suspension bridge in Busan which experienced several times repair and reinforcement after completion in 1934. The bridge is under demolition for extension and restoration work since 2011. The purpose of this research is to establish data base about modern concrete. The mix design of the concrete is like that cement : fine aggregate : coarse aggregate = 1 : 2 : 4 or 1 : 3 : 6 by the parts. The compressive strength is in the ranges from 50 to 55 MPa and the elastic modulus is in the ranges from 25 to 35 GPa. From the fact that the deviation is less than 10 %, considerably high quality control was conducted in those days. The carbonation depth is 5.92 cm at the bridge post and 14.3 cm at the machine room. That is why ocean environment keeps the high humidity. The diffusion coefficient of chloride ion through the pores in concrete is 1.052e-12 $m^2/s$ from the regression analysis using the experiment data. The water cement ration is estimated at approximately 35 % in case if the concrete using ordinary Portland cement.

부산항대교는 부산 남구 감만동과 영도구 청학동을 잇는 총 길이 3,368m 규모의 국내 최장 강합성 사장교로 5월 22일 개통하였다. 특히 야간에는 경관조명 등 '빛의 연주'라는 주제로 화려한 볼거리를 구성하여 '부산 해상순환도로'를 활용한 새로운 관광명소로 운영할 계획이다. 그러나 부산북항 통항 선박의 경우 화려한 조명 및 부산항 배경광 등으로 인해 선박통항 시 위험성이 높아질 것으로 우려되며, 이번 연구를 통하여 부산항대교 경관조명에 따른 부산북항 도등 기능검토 및 부산북항 선박통항안전성에 관한 검토를 하고자 한다. 실선박을 이용한 현장조사를 통하여 현재 설계중인 부산항 도등의 기능을 재검토하고, 부산항대교 경관조명 및 부산북항 배경광에 따른 선박 통항 안전성을 검토한다.

Recently, due to a decline in traditional industrial function and recession of the real estate business, urban coastal settlement areas have been promoted in a regeneration way using historical cultural values rather than overall development approach. This study investigated the regional assets of water-front area around Yeongdodaegyo Bridge in Yeongdo-gu, Busan and classified them into physical social economic assets and then, presented the integrated regeneration approach that can increase the place value of this area. First, physical regeneration proposed a regional revitalization plan by considering place and cultural characteristics and second, social regeneration by considering the regional brand through storytelling and third, economic regeneration by considering historical cultural characteristics. Regional assets-based culture experience can be provided by building cultural tourism infrastructure through this and local economy and local community activation can be expected by providing urban vitality base of coastal settlement areas.

Fatigue strength of temporary steels and painted structural steels corroded under outdoor atmospheric environments is not clear. In this study, fatigue tests were carried out on steel plates which were cut off from 7-year-old temporary structural member under subway construction environment and from 75-year-old Yeongdo bridge member under marine atmospheric environment. After removing corrosion production on the steel surface, 3-dimensional surface geometry of the corroded steel was measured at intervals of $1.0{\times}1.0mm$, and corrosion characteristics such as minimum, maximum and mean values of residual thicknesses were calculated. From the fatigue test and FEM analysis results, the relationship between corrosion characteristics and fatigue behavior was presented, and change in fatigue strength of the unpainted and painted steels corroded in outdoor environments was also presented.

조형미를 가진 콘크리트 구조물을 만들 때는 형태를 만들어 낼 수 있는 거푸집과 함께 시공에 필요한 기술과 훌륭한 기능인력이 필요하다는 것을 잊어서는 안 된다. 서해대교, 테헤란로의 건축물 등 여러 종류의 콘크리트 구조물을 만드는 데에는 거푸집이 매우 중요한 역할을 한다. (사진 1, 2)(중략)

The followings are the results of study about morphological variation of mussel, Mytilus coruscus collected respectively from Sanyang-myeon Tongyeong-goon Gyeongnam on 13th January, Yeonwha-do Yokji-myeon Tongyeong-goon Gyeongnam on 15th May and down below the Yeong-do Bridge Busan on 20th August, 1964. The biggest mussel of the above three areas have been from Yeong-do Bridge, whose shell height is 164.1 mm, shell length 77.8mm, shell breadth 52.2mm, total weight 291,9g and shell length is as follows : from Yeong-do Bridge L=0.4954H + 1.9516, from Sanyang-myeon L=0.3718H + 14.145, from Yeonwha-do L=0.4074H + 9,6610 The relationship between shell height and shell breadth is as follows : from Yeong-do Bridge B=0.3426H + 0.2052, from Sanyang-myeon B=0.3084H + 3.6183, from Yeonwha-do B=0.3507H + 0.8028 In view of the above relationship, it is concluded that the slope value of mussel, nearer to the inshore from the off-sea, is similar to that of M. edulis, from which are can presume that M. coruscus could be changed in shell form according to its environment. Growth curve between total weight and shell height is as follows : from Yeong-do Bridge W=0. 00020469 $$H^{2.79745}$ from Sanyang-myeon W=0.00061512$H^{2.53708}$ from Yeonwha-do W=0.00016965$H^{2.83960}$

The aim of the study is to examine the applicability of FRBRoo / CIDOC CRM to conceptualize information resources for localities. It attemps to establish the conceptual structure and the relationship of them and seeks ways to apply the model. For this purpose, almost 30 articles specially in localities research were analysed and categories of information resources for localities were identified. After examining conceptual model in cultural information management sectors (library, museum, archive), 6 case of conceptualization were attempted based on FRBRoo / CIDOC CRM. In conclusion, it presented that FRBRoo / CIDOC CRM could be applied to various type of information resources for localities and that it could be possible to represent information resources based on particular space(place, local) through the conceptualization.

Bascule bridge, with its use to help vessels ply, has a several examples overseas of being serviced for more than decades years by careful maintenance, admitted its significance as landmarks for its rareness. Yeongdo Bridge, the sole bascule bridge in Korea was reconstructed in 2013 after being demolished because of its corrosion and aging, and now operates once in a day. Recently, safety inspections are executed thanks to demands getting higher for maintenance and safety of bridges, but measurement and analysis about bascule bridges are scarce. This study includes the analysis of the bascule bridge's behavior such as stress, vibration and reaction in normal condition and while it lifts up, based on measurement. We expect that this study will be used as an initial data to compare and confirm bridge's changes as service year and the number of operation increase.
