This study intends to investigate the measuring scales, locations and scales through arrangement plans for a research on construction plans. Through an analysis of the artifacts-measuring scales, the relation of two scales found, which further helped suppose the measuring scales applied during the foundation period. Southern dynasties-scale was still used even after the capital was transferred to Sabi till Tang-scale was introduced. Tang-scale was used for Buddhist temples mostly founded in the 7th century. On the other hand, Goguryo-scale seemed to be used almost at the same period as Southern dynasties-scale used, but it seemed that Goguryo-scale disappeared earlier than Southern dynasties-scale. The locations of Buddhist temples could be classified into mountains, flatlands and mountain valley. Buddhist temples founded in mountains were mostly small-sized, but ones located on flatlands could secure flat fields through mounding operations. In addition, through location conditions of Neungsa and Wangheungsa, it was possible to find out the district setting of Sabi Capital Castle. Finally, the expansion range of Buddhist temples were found to be towards the east and the west. As for the scales of temples according to such conditions of location, it was found a similarity in Temple sites. In general, it was possible to assume that the scales of Buddhist temples tended to be expanded along with spatial expansion and there were regular systems in Buddhist temples related to the Royal family. Through the analysis of arrangement plans between individual buildings, it was found that the basic arrangement of Gate-Pagoda-Main Hall-Lecture Hall was preserved, but the proportion of distances between individual buildings varied depending on cases. As a result, there were differences between scales of entire building sites, construction subjective influences and master plan for each location of a Buddhist temple.

This study is one that estimates the architectural composition as well as the location of guest house of Haemi Eupseong on the basis of the analysis of modern and contemporary data related to Haemi Eupseong. It is significant that this study has presented an opinion that can become a practical basis for the historical research of the prototype of Haemi Eupseong of the late Chosun Dynasty through the analysis of modern and contemporary data that had been unsatisfactory among the fruition of studies conducted in relation to Haemi Eupseong. The outcomes achieved by this study are as follows. Firstly, it was verified that the guest house of Haemi Eupseong that has been restored is one that has different architectural composition than the prototype of the late Chosun Dynasty and is restored in a different location. Secondly, in respect of architectural composition of guest house found by the analysis of the picture, it was confirmed that the government office has one step higher than the double-wing house in the form of the roof. Thirdly, the location of the guest house of Haemi Eupseong of the late Chosun Dynasty is judged to be the periphery area where the current restored guest house is located, which is where the teachers' building of Haemi elementary school was located. Fourthly, the prospect of the guest house of Haemi Eupseong is decided to be similar direction to the current restored guest house with the greatest possibility of having the same direction with the arrangement of teachers' building of Haemi Eupseong elementary school.

특정 위치에 주의를 주게 되면, 그 위치에 있는 사물을 시각적으로 처리할 때에 시간 해상도가 저하되며, 이러한 저하는 큰세포(parvocellular)와 작은 세포(magnocellular)의 상호 억제적 연결에 기인하는 것이라고 주장이 제기되었다. 이와는 다르게, 시각 주의가 같은 위치에 연속적으로 제시되는 자극들간의 시간적 겹침을 유발하기 때문에, 주의에 의한 시간 해상도 저하가 관찰되었을 가능성이 있다. 본 연구에서는, 이 가설을 검증하기 위해, 배경 대비 자기의 극성이 다른 두개의 자극들을 사용해 자극 제시 순서를 판단하는 과제를 실시했다. 밝기 극성이 다른 자극들은 초기 시각 처리과정에서 서로 다른 경로를 통해 처리되기 때문에, 주의가 주어진다고 하더라도 시간적 중복이 촉진되지 않을 것이다. 실험 결과, 실험 참가자들은 시각 단서가 주어지지 않은 위치에서보다 주어진 위치에 나타난 자극들의 제시순서를 더 정확하게 판단했다. 반면, 같은 밝기 극성을 가진 두 개의 자극에 대한 제시 순서를 판단해야 했을 때에는, 시각 단서가 주어진 위치보다 주어지지 않은 위치에 나타난 자극들에 대해서 더 정확하게 제시순서를 보고했다. 이러한 결과는, 시각적 주의가 자극 신호의 시간적 중복을 유도함을 통해 시각적 시간해상도에 영향을 미친다는 것을 의미한다.

In carrying out the prior review on environmental conditions for basic plan of public waters reclamation, the important item is review on conditions of location on prearranged reclaimed land. In this study, environmental assessment which needs careful consideration in the first stage of selecting location is presented by analyzing environmental impact assessment on public waters reclamation projects for about 10 years. The assessment index for alternative comparison is divided into two parts according to importance level. What is most important in alternative comparison is the comparison on direct influence due to reclamation. In other words, it figures out damaged extent of natural shoreline as well as intertidal and infralittoral zones. Comparing influence extent due to reclamation through the 1st comparison on this is regarded as to be important. In case there is no significant difference by alternatives through the 1st assessment, the 2nd assessment should be carried out. In the 2nd assessment indexes are damaged quantity of benthic organism, change in seawater current, erosion, accumulation and exchangeable rate of seawater. The plan for selecting optimal location which minimizes environmental influence in establishing public waters reclamation plan is demonstrated through model cases. For this, 3 districts which have similar environment and scale are selected, and then comparison on location alternative is made through environmental assessment index. In addition, the comparison on 3 arrangement alternatives are conducted, targeting certain areas. It is thought that carrying out comparison review on respective areas in the same cities and counties, not merely comparing arrangement plan by selecting 1 targeting area in advance, is the most appropriate. Besides, selection of arrangement plan considering environment, which minimizes damage of natural shoreline and influence due to change of seawater current is required in alternative comparison on arrangement plan as well. In case of the prior review on environmental conditions though alternative comparison method presented in this study is carried out, it is safely said that the influence on ocean environment due to public waters reclamation can be minimized.

In the study, CE-QUAL-W2 was used and its examination and correction were conducted targeting 2001 and 2003 when the condition of rainfall was contradicted. Using the proved model in 2003, a scenario was implemented with management of locations for dewatering outlets and actual data for dam management in 1987 when inflow and outflow level were almost same. In case of the scenario which the location of dewatering outlets was 5m higher than usual location, exclusion efficiency for turbid water inflow at the beginning of precipitation was good. In case of the scenario which the location of dewatering outlets was 10m lower than usual location, exclusion efficiency for excluding turbid water remained in a reservoir after the end of precipitation. However, the scenario applying dam management data in 1987, exclusion efficiency was relatively low. In the scenario, power-generating water release spot at EL.57m for first four days after the beginning of precipitation, EL.52m for 5th to 8th and EL.42m from 9th days. An analysis of the scenario reveals that both excessive days exceeded 30 NTU and average turbidity levels were decreased comparing before and after the alteration on outlets. The average turbidity levels were decreased by minimum of 55% to maximum of 70% and 30NTU exceeding days were decreased by 45 days at maximum. Also, since it could exclude most of turbid water in a reservoir before the destatifcation, the risk for turbid water evenly distributed in a reservoir along with turn-over could be decreased as well.

Object recognition and object location have always drawn much interest. Also, recently various computational models have been designed. One of the big issues in this domain is the lack of an appropriate model for extracting important part of the picture and estimating the object place in the same environments that caused low accuracy. To solve this problem, a new Salient Based Bag of Visual Word (SBBoVW) model for object recognition and object location estimation is presented. Contributions lied in the present study are two-fold. One is to introduce a new approach, which is a Salient Based Bag of Visual Word model (SBBoVW) to recognize difficult objects that have had low accuracy in previous methods. This method integrates SIFT features of the original and salient parts of pictures and fuses them together to generate better codebooks using bag of visual word method. The second contribution is to introduce a new algorithm for finding object place based on the salient map automatically. The performance evaluation on several data sets proves that the new approach outperforms other state-of-the-arts.
