In photogrammetry, the accuracy is analyzed by using the coordinate of the targeted position determined by the geometric principle, thus, the reliability depends on the accuracy of the coordinate of the targeted position. Thereby, geographic surveying is essential to perform such tasks, and it requires approximately $30{\sim}50%$ of total cost and times to produce a finalized map. The main purpose of this study is to determine the configuration of the disposition of minimum datum points and their configuration, which were determined by surveying values available through using the structure of block model based on the aerotriangulation. ortho projection image was produce and digital topographic map was achieved by the optima model(CASE7). We also performed comparative analysis about the result of local datum point and the accuracy of overlapping based on the surveying results. Consequently, it is possible to analyze the unknown position accurately with the optimal model., CASE 7, which is the minimum datum points configuration required to block adjustment. Furthermore, this optimal model, which provides the minimum datum points, results costs and time saving effects compared to the previous methodology.

This study develops an approach to assign numbers of facilities (rectangular shape) in a given plant and compares the test results by proposed approach with those by approaches in the literature. An improvement approach is proposed to minimize material handling cost given initial layout. Like popular heuristic approaches, the developed heuristic approach employs interchange routine to improve material handling cost in current layout. Horizontal interchange and vertical interchange procedures are applied to obtain better solution. Also, it is possible to rotate facility layout when the sizes of both facilities are same. However, the proposed approach generates good solutions without shape distortion. That means the shape of facilities remains rectangle in the final solution. In addition, the improve approach can find global optimal solution from local optimal solution by applying Tabu search technique. Based on 25 test problems in the literature, we obtained better solutions than other facility layout approaches in the literature when there are many facilities.

액체로켓엔진 조립을 위한 엔진 조립장이 국내에 구축되어야 하며 이에 대하여 국내의 사례가 없으므로 해외 엔진 조립장의 사례를 조사하였다. SNECMA, EADS, Rocketdyne 등의 조립장의 구조, 레이아웃, 청정설비, 크레인 등을 조사하였다. SNECMA 엔진조립장은 Vulcain 엔진의 대형엔진 조립라인 및 HM7, Vinci 엔진 등의 소형엔진 조립라인으로 구성되어 있다. 청정도는 코어 및 Subassembly 조립실은 100 K class 이며, 기타 나머지 조립공간은 300K class로 구축되어 있다. EADS의 엔진 조립장은 중앙에 연소기 부품을 가공하는 가공장비들이 배치된 하이베이 구역이 있으며, 이 하이베이 구역의 측면에 사무실, 측정실, 회의실 등의 로우베이 기능실들이 배치되어 있다. Rocketdyne 엔진 조립시설은 청정도 300K class이하의 엄격한 청정도 관리가 없는 것으로 보이며 치구형태의 개별 플랫폼을 사용하여 공간 활용을 효율적으로 할 수 있도록 하고 있다.

Comics has three components: cuts, gap between cuts, speech balloons. Still, it is true that speech balloons are not commonly subject to the study for comics. A few preceding researches pinpoint exactly the morphological features and functions of speech balloons. In today when webtoon becomes generalized, these features and functions are continued as they are and are used in webtoon. We can catch that speech balloons are also affected since the environmental elements of web induce the change in the overall comics directing. There are two perspectives to sort out the features of speech balloons: first, the placement issue of speech balloons. The unlimited expansion of web space gives the environment for comicss to use the gap between cuts as wide as they can. It leads to turn out some of the ways to place the balloons, so we can sort them out general placement, exterior placement, the upper and lower placement, scroll-use type. Second, as the directing techniques for webtoon become digitalized by the morphological issue, speech balloon itself has been expanded its ways to express by various expression methods. Analyzing and classifying, recording the newly emerged conditions on the preceding study are worthy of trying and will become the cornerstone for the follow research.

일체형 원자로에는 노심지지원통과 원자로용기 내벽사이의 환형 공간을 나선으로 감는 형태인 일체형 관류식 나선형 증기발생기와 증기발생기를 여러 개의 모듈로 나누어 환형 공간에 배치하는 형태인 모듈형 관류식 직관형증기 발생기가 가장 적합한 것으로 판단되어 두 가지 형태에 대한 개념을 설정하였다. 일체형 관류식 나선형 증기발생기는 전열관 집합체, 지지구조물, 하강유로, 그리고 증기 및 급수 헤더로 구성되어 있다. 모듈형 관류식 직관형 증기발생기는 개개의 모듈이 별도로 운전될 수 있는 12개의 모듈로 구성되며, 원자로용기를 관통하는 배관의 수를 줄이기 위해서 급수관이 증기관의 안쪽에 있는이중배관 개념을 사용한 것이 특징이다. 모듈형 관류식 직관헝 증기발생기가설계 및 제작이 용이하지만 높이를 줄이기 위한 방안으로 두 가지 개념이 조합된 모듈형 관류식 나선형 증기발생기도 검토하였다.

The single photo method has a lot of applications in forestry, traffic accident managements, industry, criminal investigation, and in daily life. In this study a new single photo method was developed by classifying into the Space resection method and the 2 Dimensional Perspective Transformation method. Metric and nonmetric cameras were used to analyse the accuracy by means of single photo method, and the errors in coordinates and lengths were studied by changing the number and arrangement of control points to obtain the optimum condition for the single photo method. The influence of number and arrangement of control points on the accuracy was relatively small in case of the Metric WILD P31 and ASAHI PENTAX 6$\times$7 cameras, where as for errors it was a major factor in the Non-metric Nikon FM2. To overcome these defects, at least 6 control points should be used for the errors to be convergent and they should be distributed evenly over the surveying area. It was found that accuracy increased as the object to be photographed was placed in the perpendicular direction to the axis of camera.

This paper presents an AP placement technique considering indoor location-awareness and examines its performance. The proposed AP placement technique is addressed from three performance metrics: location-awareness and AP-based wireless network performance as well as its cost. The proposed AP placement technique consists of meta-heuristic algorithms that yield a near optimal AP configuration for given performance metrics, and deterministic algorithms that improve the fast convergence of the near optimal AP configuration. The performance of the AP placement technique presented in this paper is measured under the environments simulating indoor space, and numerical results obtained by experimental evaluation yield the fast convergence of a near-optimal solution to a given performance metric.

We suggest a new spatial linear interpolation method to substitute linear interpolation method which widely used in transportation engineering to impute the missing daily traffic volume. We layout daily traffic volume which is time series data over the virtual lattice space to consider the spatial correlation. We used Moran Index to evaluate the spatial correlations among daily traffic volume in same week and same date traffic volume by week considering the circularity of daily traffic volume. For real application, we used daily traffic volume on November, 2004 provided by Korea Institute of Construction Technology(KICT) and transformed daily traffic volume to 4 times 7 virtual lattice space to reflect the spatial correlation. Finally we showed that the spatial linear interpolation method has good performance for missing data imputation based on MAPE, RMSE, and Theil's U criteria.
