Springback is a common phenomenon in sheet metal forming, caused by the elastic recovery of the internal stresses after removal of the tooling. Recently, advanced high strength steels (AHSS) such as TRIP and DP are finding acceptance in the automotive industry because their superior strength to weight ratio can lead to improved fuel efficiency and assessed crashworthiness of vehicles. The major troubles of the automotive structural members stamped with high strength steel sheets are the tendency of the large amount of springback due to the high yield strength and the tensile strength. The amount of springback is mainly influenced by the type of the yield function and anisotropic model induced by rolling. The discrepancy of the deep drawn product comparing the data of from the product design induced by springback must be compensated at the tool design stage in order to guarantee its function and assembly with other parts. The methodology of compensation of the low shape accuracy induced by large amount of springback is developed by the expert engineer in the industry. Recently, the numerical analysis is introduced in order to predict the amount of springback and to improve the shape accuracy prior to tryout stage of press working. In this paper, the tendency of springback is evaluated with respect to the blank material. The stamping process is analyzed fur the front side member formed with AHSS sheets such as TRIP60 and DP60. The analysis procedure fully covers the binderwrap, stamping, trimming and springback process with the commercial elasto-plastic finite element code LS-DYNA3D.

The objective of this study was to investigate the effects of hot- and cold-boning on sarcomere length, drip loss and protein solubility of post-rigor porcine longissimus muscle. A total of ten pigs(borrow, 100$\pm$5 kg) were randomly selected at a commercial plant and the carcasses were split in half after slaughter. The longissimus muscle of the left side was dissected and chilled at 0$^{\circ}C$ after trimming of subcutaneous fat whereas the right side carcasses were served for cold-boning after chilling for 24 hrs. The temperature, pH and sarcomere length of porcine longissimus muscle were measured at postmortem 1, 3, 6, 12 and 24 hours. Drip loss, cooking loss, Minolta L*a*b*, shear force and protein solubility were measured at postmortem 24 hrs. The pH of cold-boning samples was rapidly decreased whereas temperature and sarcomere length of hot-boning samples were rapidly decreased during 24 hrs of chilling. Hot-boning muscles showed significantly (P<0.05) higher pHu and shorter sarcomere compared with cold boning muscles because of cold shortening. However, there were no significant differences in drip loss, cooking loss and shear force value between hot- and cold boned samples. The samples of hot-boning showed lower Minolta L* value and higher sarcoplasmic protein solubility compared with cold boned samples. These results suggest that the pale color changing of porcine longissimus muscle could be inhibited by hot-boning due to rapid chilling of the muscle although sarcomere length could be shortened because of cold shortening. Also these results show that hot-boning of porcine carcass could have a high protein solubility without negative effects of drip loss or tenderness of porcine longissimus muscle.

Generally, the vertical roll process is used to achieve extensive width reduction in hot strip mill. However, it is difficult to avoid the defects such as dog-bone and seam-defect. The sizing press has been developed in response to the defects mentioned above. Especially, this study is carried out to investigate the deformation of slab by two-step sizing press. The deformation behavior in the width sizing process is more favorable than that in conventional vertical rolling edger. The objective of this study is to determine the optimal anvil shape parameters in the sizing press with two-step die from the viewpoint of edge-seam length. In general, the edge-seam defect occurs parallel to the rolling direction at both edges in horizontal rolling process after sizing press. The optimal combination of the parameters is determined by FE-simulation and Artificial Neural Network (ANN). The slab deformation in sizing press with convex anvil is analyzed by FE-simulation. The most suitable profile of the anvil is also discussed fur the improvement of trimming loss because of the side seam defect by FE-simulation and ANN.

Hot springs development will be more activated with the five-day work week system than before. Nevertheless, investment and development achievement of hot springs has not resulted in a successful performance to foster townships, and this calls upon locals to build a guideline to develop hot springs. This study intends to analyze laws on hot springs, which influence mostly on the hot spring development, to gather up the information on the present state of the development, and to suggest considerations for further development plans. Features of the hot spring development are as follows: One is that metropolitan cities will discover hot spring resources more than small cities. Therefore the development will be twofold : one for resort tour and the other for one-day rest and recreation. In addition, Korean laws on hot springs are more site development-oriented to support tourism and recreation than to protect environment and discover unused resources. This makes hot spring development easier and efficient being supported by hot spring law, law on territory development and use, and tourism promotion law. On the other side, planned landscape trimming can be uniformized and unharmonized in terms of local identity and environment-friendliness. This is why careful considerations such as goods and bads of the local resources, local history and culture are needed in hot spring development. A long-term development project should include remodeling based on local identity and development trends. The third point indicates that Korean hot springs development has recorded relatively low performance due to difficult private capital attraction, and a high fence on land purchase and development approval. It is essential to release restrictions on the hot spring development-especially on those whose development performance has not been successful so that best practice can be supported by the government in remodeling and marketing. New plans on hot spring development should be also examined based on developer's capacity and local authorities' volition on the plan. Last point shows that most hot springs development plans have been designed only based on territory utilizing plan and facilities arrangement, not considering much on fund-raising, operational plan or feasibility analysis. Therefore the tourism promotion law should reinforce guidelines on tourist site approval system by supplementing criteria. At the same time, an education on tourism development planning is necessary to deepen developers' understanding, since most developers are experts more on city development, landscape architecture, designing, constructing and engineering than tourism development.

도기 말머리장식 뿔잔은 부산광역시 동래구 복천동 제7호 무덤에서 출토되었다. 뿔을 본떠 흙으로 만든 것으로 액체를 담아 사용된 것으로 생각되며 신라·가야 지역의 무덤에서 여러 형태의 뿔잔이 다수 출토되었다. 뿔잔 2점이 한 쌍으로 출토되었으며 크기는 서로 다르지만 전체적인 형태와 제작 기법은 거의 동일하다. 이번 처리를 마친 유물은 발굴된 두 개의 뿔잔 중에 큰 형태에 해당하며 구연부를 중심으로 말머리장식 쪽으로 균열이 두 군데에 있었으며 소실된 편도 관찰되었다. 뿔잔은 말의 가슴을 바닥에 닿게 하고 이를 중심으로 한쪽은 말머리를 장식하고 반대쪽은 원추형의 뿔잔 입구가 있고 뒤쪽에 2개의 다리를 붙여 뿔잔의 균형을 맞춘 U자형의 형태이다. 뿔잔의 표면은 물레로 성형하고 말머리와 연결된 부분은 깎아 다듬은 자국이 있다. 말머리의 형상은 간결하게 귀·눈·코와 입 등 특징을 잘 파악하여 사실적으로 표현했으며 색은 회색이다. 이 연구에서는 비파괴 상태조사를 통하여 내부 구조를 알아보는 등 제작 특성을 알아보고자 하였다. C·T영상을 통하여 제작 기법을 알아보고 상태를 진단하여 과학적 보존처리를 통해 유물을 안정화 하였다. 보존상태 정밀진단 결과, 구연 두 곳에 결손부분이 있고 균열이 연장된 것을 확인하였다. 이 중 한 곳은 균열에 이격이 더해진 상태로 접합이 된 상태였다. 과거 접합이 이루어진 재료를 수습하여 적외선 분광분석을 실시한 결과, 질산셀룰로오스계 수지가 사용된 것을 알 수 있었다. 따라서 이번 보존처리는 과거의 재료를 제거하고 균열의 확산을 방지하는 데 중점을 두고 진행하였다. 보존처리 전 상태조사 및 과학적 조사를 실시하여 도기 말머리장식 뿔잔(보물)에 대한 자료를 확보하고, 이를 바탕으로 효과적인 보존처리 방안 모색, 기존 접착제의 안전한 제거 및 복원 재료의 가역성을 고려하여 선택하고 보존처리는 전문가 자문회의를 통해 최상의 방법으로 실시하였다.
