The object of this study is to develop the trip assignment model from the correlation graph of volume and speed, and the capacity of street and zone. The synopsis of this study is follows: 1. Frame assignment net-work for each zone as Fig 1 and calculate the distance (L??) between zones which is average length of streets linking the centroids of two zones and calculate the trip distribution according to the next steps. 2. The 1st trip assignment: Take only the trip genetared in each zone as the 1st trip assignment (U??). 3. The 2nd trip assignment: Choose the service speed for the 1st trip assignment and calculate the travel time (T??) by the formula(9). Then, select 3 assigning route by the Critical Path Method and calculate assignment ratio(r??) and trip assignment (U??) by formulas (10) and (11). The 2nd cumulative trip assignment for each zone and assigning route can be calculated from the formulas (12) and (13). 4. The 3rd and 4th trip assignment: The 3rd trip assingment is for the C.B.D. and sub-C.B.D. The 4th trip assignment is for the outskirts and the reat of urban district excluded in the 3rd trip assignment. The calculation process or the 3rd and 4th trip assignment that are identical that of 2nd trip assignment,are formulas (13), (14), (15) and (16). 5. According to the magnitude of the capacity for street and zone, the process will be selected as follow: Fig 1 is the process for demand trip assignment in the case of unlimited capacity and Fig 2 is that for actual trip assignment in the case of limited capacity.

With the rapid development of computing technology, multi-view video is attracting extensive interest recently due to its greatly enhanced viewing experience. In this paper, we propose an integrated display solution model and present the prototype system for multi-view video. The player can display and verify the multi-view video. For verifying the accuracy of synthesizing graphics, it can display in both 2D and 3D mode, and save frames into various format. And, in experiments we can select not only degree of stereoscopic effect but also number of intermediate views between real cameras. With this system, users are able to select their desired viewing directions and enjoy many exciting visual experiences, such as view switching, freeze and rotate and view sweeping, with great freedom.

This study(Ⅱ)(Ⅲ) treated the calculation method of the capacity of urban street or zone. The process of computation method that is shown in Fig.1 is follows. 1. Classified intersections accroding to the existence or nonexistence of signal and calculated service volume (C?), average queuing time(T?) and average queuing volume (W?) for each intesection. (refer to equations (10), (16) and (23)) 2. Calculated the overall travel speed(V?) between the adjacent intersections from the standard overall travel speed(V?) that is shown at table 6, the average queuing time(T?) and the distance (L?) between adjacent intersection for each service level. (refer to equation (19)) 3. Classified the means of capacity for street or zone into the capacity that can pass over the street or the zone and the capacity that can be dealt in the street or the zone. And taked saturation degree and overall travel speed as the factors for deciding service level. 4. Taked the smallest capacity among a number of intersection capacities as the capacity(SC?) that can pass over the street in the case a given street is consisted of a number of intersections and through lanes. And taked the sum of the queuing volumes at the intersections and the volumes on the through lanes as the capacity that can be deal in the inner part of the given street. 5. Taked the sum of capacities that pass over the streets crossing the zone boundary as the capacity that can pass over the zone(ZC?) and taked the sum of capacities that can be deal in the inner part of the streets (ZW??) as the capacity that can be deal in the zone.

본 연구는 상악 유전치부의 치간공간과 인접면 우식의 상관관계를 평가해보고자 하였다. 익산에 거주하는 만3-7세의 어린이 555명을 대상으로 하였으며 탐침이 통과하는지 여부로 치간공간이 있음과 없음으로 분류하였고 와동이 형성되었거나 법랑질 표면이 연화되었을 경우 인접면 우식이 존재하는 것으로 판단하였다. 연구 결과 다음과 같은 결론을 얻었다. 1. 상악 유전치부의 치간공간은 영장류 공간이 77.4%, 발육공간이 유측절치와 유중절치 사이에서 54.4%, 양유중절치 사이에서 39.0%로 나타났다. 2. 인접면 우식발생율은 우측유견치가 6.3%, 우측유측절치가 14.7%, 우측유중절치가 33.5%, 좌측유중절치가 33.7%, 좌측유측절치가 16.0%, 좌측유견치가 4.7%로 나타났다. 3. 치간공간의 수가 많을수록 상악 유전치의 우식발생율은 낮아졌으나 그 상관관계(r=0.024)는 미약하였다. 4. 상악 유전치부에 공간이 존재하지 않을 경우 존재할 때 보다 평균 우식발생율이 높았으며, 치간공간이 전혀 존재하지 않는 경우 한 곳이라도 치간공간이 존재하는 경우보다 평균 우식발생율이 2배 이상 높은 것으로 나타났다. The purpose of this study was to assess the relationship between interdental spaces and proximal caries in maxillary anterior primary teeth. 555 children aged 3-7 inhabit in Iksan were divided into two groups, depending on the presence of interdental space which was detected by a dental explorer. They were determined to have proximal caries if cavity was formed or the enamel surface was softened. The results were as follows : 1. Regarding interdental spaces, 77.4% had primate spaces; 54.4% had developmental spaces between central and lateral incisor, and 39.0% between central incisors. 2. Interproximal caries incidences in right primary canine, lateral incisor, and central incisor were 6.3%, 14.7%, and 33.5%, respectively. Also interproximal caries incidences in left primary central incisor, lateral incisor, and canine were 33.7%, 16.0%, and 4.7%, respectively. 3. Children with more interdental spaces had less caries incidence, but the relationship was weak(r=-0.024). 4. The mean caries incidence was higher in absence of interdental space of maxillary primary incisors than in presence of space. The mean caries incidence with no interdental space was twice as high as that with presence of interdental space.

To provide seamless networking for mobile devices, the automatic selection of the most suitable AP(Access Point) as well as the maintenance of seamless session during hand-over have been an important issue for automatic hand-over, so that seamless session is usually not guaranteed. Supporting seamless mobility makes mobile networking service easy to implement. In this paper, we propose a Linux-based seamless networking solution that can overcome aforementioned disadvantages. The efficient selection of AP can be made in the Linux environment according to the value of link quality. Active hand-over is supported and automatic AP management is designed for the mobility of wireless mobile devices. Furthermore, automatic access to wireless networks is on of the merits.

The study comprises 3 parts. Part I in this paper, H.C.M.(1965) is treated with the application of queuing matrix theory to service volume of intersection and of the distance between adjacent intersections to overall travel speed. Step 1. Calculate saturation degree Ρfor the comparison of the comparison of the capacity with the service volume at intersection; ?? where in C??=service volume at intersection C??=capacity of urban intersection Step2. Calculate average queing time W by entering aboved saturation degree p to F.V. Wabster formula; ?? where in W=average queuing time in second C=cycle time in second q=average arriving volumes in vehicles/hour S=average departing volumes in vehicles/hour G=green time in second ?? Step3. Calculate overall travel speed V from average queuing time W and distance lr between adjacent intersection; ?? where in V=overall travel speed in km/hour l??=typical distance between adjacent intersections used in the H.C.M.(1965)in km V??=typical overall travel speed for a level of service in H.C.M.(1965)in km/hour ?? The results of the aboved study are as follows. 1)Load factor is a convenient median with which to grasp traffic development, but is not suited to be measured quantitably. 2)The saturation degree ??does not conform to the V/C ratio which is constant for a given load factor regardless of the width of approach to intersection in H.C.M.(1965). 3)Urban street service volume by systematic interrelating the intersections and streets can be calculated with the introduction of the saturation degree ??, the average queuing time W and the distance ??,between the adjacent intersections.

To provide seamless networking for mobile devices, the automatic selection of the most suitable AP(Access Point) as well as the maintenance of seamless session during hand-over have been an important issue in wireless mobile network field. Despite such importance, previous activities do not provide solutions for automatic hand-over, so that seamless session is usually not guaranteed. Supporting seamless mobility makes mobile networking service easy to implement. In this paper, we propose a Linux-based seamless networking solution that can overcome aforementioned disadvantages. The efficient selection of AP can be made in the Linux environment according to the value of link quality.

The characteristics of ichthyofauna and fish community in the Lagoon Gyeongpo, Korea were investigated from May to October 2005. The total number of fish caught during the period was representing 26 specis and 18 families. Most dominant species was T. hakonensis(50.65%) and subdominant specis was A. flavimaus(25.41%). K. punctatatus(11.07%), M. cephalus(6.53%), E. japonicus(1.46%), C. castaneus(1.01%) were also numerous. The total biomass of collected fish showed 147.00kg, 135.83kg, 85.60kg,23.76kg, repectively. A pattern of the fish community according to seasonal veriations appear to be related tp spawning periods of species. Comparison of the ichthyofauna in present study with the references from early years suggests that there has been a gradual decrease, in composition, of primary freshwater specis accompanying with the increase of peripheral freshwater and seawater specis.
