Recently, a MMORPG(Massively Multi-play Online Role Playing Game) has built distribute server by Seamless world. This paper proposes an efficient collision detection method. DLS is used to dynamically adjust spatial subdivisions in each the boundary regions of distribute server We use an index table to effectively utilize the relationships between in the nodes and can perform the collision detection efficiently by reconstructing nodes of the tree. Also, we maintain the information for the boundary region to efficiently detect the collections and adjust the boundary regions between distributed servers by using DLS. As the DLS uses pointers, the information for each server is not needed and the boundary regions between the distributed servers are efficiently searched. Using node index points, the construction table can be made to find between ray and neighborhood node, In addition, processes for Network traffic reduce because a copy of the boundary regions is not needed when a object moves with realtime.

사후 저장기간 중 어육내에 진행되는 단백질 분해에 어육 자체효소와 새균활동 중 어느 쪽이 기여하는 바 큰가를 분별하기 위하여 금방 죽인 볼낙류(Sebastodes)의 어육을 무균방법으로 잘라내어 4 OZ 유리용기에 넣고 플라스틱으로 된 나사뚜껑으로 밀봉한 후 감마선 조사하지 않는 군(무균육과 무군육에 단백질 분해성 Pseudomonas 를 접종한 것으로 세분)과 0.5과 2.0 Mrad 선량 조사한 군(무균육, 조사 전에 접종시킨 어육, 그리고 조사후에 접종시킨 어육으로 세분)으로 나누며 $0^{\circ}C$에서의 저장 중의 어육의 총균수, pH, 관능 상해, 그리고 0.5M KCl 및 $70\%$ ethanol 가용성 총질소와 Amino-N을 검측함으로써 어육 단백질 분해 과정을 조사하였다. 0.5 Mrad 감마선량은 무균 어육에 접종된 $10^6$ per gm Muscle Pseudomonas sp.를 완전 사멸시키는데 충분하였으므로 완전한 무균상태와 처음부터 단백질 분해성 세균활동이 활발한 상태에 놓여 있는 어육 내에 진행되는 단백질 분해과정을 비교할 수 있었다. 기름지지 않는 어류에 속하는 볼박 어육의 저장 중에 일어나는 pH의 상승, 관능상태의 저락, 그리고 단백질 분해에서 오는 총질소와 Amino-N의 축적은 모두 세균의 번식활동과 직접 관련되어 있으며, 완전 무균 어육의 단백질 분해는 전혀 검측되지 안했으므로 통상 저장중에 일어나는 어육 담백질 분해는 전부가 세균활동에 기인됨이 확실해 졌다. 감마선 조사 직후 단백질 분해성 세균을 접종시킨 어육을 조사치 않고 접종시킨 어육에 비교할 때, 전자의 경우 세균번식이 현저히 장해 받았으며, 이에 따라 PH 상승과 총질소 및 Amino-N 축적도 상대적으로 부진하였다. 이 방사선을 조사받은 어육에 접종된 단백질 분해성 세균활동의 장해는 조사선량에 비례함이 밝혀졌다. 관능상태로 판단할 때 0.5 Mrad선을 조사받은 어육은 조사 받지 않은 것보다 선도유지기간이 2배 이상으로 연장되었다. 그러나 2.0 Mrad 선량 조사받은 어육의 선도유지는 오히려 조사 받지 않은 것보다 못하였다. 이 고선량 조사로 인한 식품의 물리적 및 화학적 변화의 해독성은 접종시킨 세균 번식 장해현상으로 나타났으며, 이 현상은 조사식품의 안전성 검측을 위한 하나의 도구로 사용될 가능성을 말해준다.

The purpose of the paper is to propose a method to give a more accurate prediction of prestress changes in prestressed concrete(PSC) bridges. The statistical approach of the method is using the measurement data of the structural system to develop a nonlinear regression analysis. Long-term prediction of prestress is achieved using nonlinear regression analysis. The proposed method is applied to the prediction of prestress of an actual prestressed concrete box girder bridge. The present study represents that confidence interval of long-term prediction becomes progressively narrower with the increase of in-situ measurement data. Therefore, the numerical results prove that a more realistic long-term prediction of prestress changes in PSC structures can be achieved by employing the proposed method. The prediction results can be efficiently used to evaluate prestress during the service life of structure so that the remaining prestress exceeds the control criteria.

In this paper, shear strength characteristics of an unsaturated soil were compared using triaxial compression tests(CD) and modified direct shear tests and thus feasibility of the newly modified direct shear testing apparatus was confirmed. The shear strength tests of unsaturated state with a soil sample, obtained from a slope where debris flow occurred at Yangpyeong in Kyeunggi province during 2010, were performed. Both tests showed a linear relationship of matric suction with the shear strength under low level of matric suction. The apparent cohesion of the unsaturated soil was also increased linearly with increase of matric suction. As results of comparing two different testing apparatus, estimated values of shear strength parameters of unsaturated soil($c^{\prime}$, ${\phi}^b$) were slightly larger in the modified direct shear tests due to constraint effect of shear box.

On the assumption that the layout of refrigerator for domestic market does not match with the eating habits of the Korean, this study suggests a way of improvement for usability of the refrigerator by re-arranging layout of inner shelves through behavioral analysis with the video ethnography. On the result of analysis, it can be found that the layout of inner shelves of the most refrigerators differs from the habits of cooking and preparing meals of Korean food, so the author propose a new layout to exchange the usage of the 3rd shelf with the vegetable box of the bottom level. It can be effective method to improve the usability by assigning appropriate usage for each shelf. To extract internal design factors of product, which is related to the specific living habits such as a refrigerator, understanding of user behavior must be accomplished at the first stage. The author found that the analysis of user behavior using the video ethnography is useful for this purpose, because it can be used to explore unpredictable design factors from user's real life.

Purpose: A water-spraying type automatic glochids removal system for cactus (Opuntia humifusa) stem was developed, and its performance was evaluated. The system was developed to reduce intensive human labor in removing glochids from cactus stem skin without inducing damage prior to further processing into value-added products. Methods: The developed system consists of conveyor and water-spraying systems. The conveyor system delivers cactus stems through water-spraying compartments and finally to a collecting box. In order to remove the glochids, rotating nozzles spray water over all areas (i.e., front and back faces and sides) of the cactus skin under controlled water pressure. Operating conditions such as conveyor speed, water pressure, angle of water-spraying nozzles, distance between conveyor belt and rotating nozzles, and angle of cactus flipping slide were adopted from our previous study and applied on the system design and manufacturing. The performance of glochids removal was evaluated by counting the number of glochids on the cactus stem before and after processing on the system. Results: The developed system performed efficiently and effectively under the pre-studied operating conditions except for the angle of cactus flipping slide. The new system had a glochids removal ratio of 94.1% without damaging the cactus skin. Considering the original number (approximately 30-60) of glochids, the remaining number was low (1-4), and most of them were found at the side edge of the cactus stem. This system can remove glochids from 360 cactus stems in 1 hr regardless of cactus size. Conclusions: The performance of the new system in glochids removal without damaging cactus skin is superior to any other existing device (i.e., brush type, rubber-friction type, and agitation type). The system is expected to be applied in cactus (O. humifusa) processing facilities.
