옥수수 전분 및 기장에 대해 방사선 재조사 후 검지 특성 평가 및 조사선량과의 상관성을 분석하였다. 즉, 국산 및 중국산 옥수수 전분과 기장(Panicum miliaceum) 분말을 비조사구, 5 kGy 조사구로 구분하여 $0{\pm}1^{\circ}C$, 암소에 12개월간 보관하면서 6개월마다 5 kGy로 재조사하여 점도, surface color, 미생물 농도 TBA value등을 측정하였다. 옥수수 전분의 점도는 저장기간 중 초기의 값을 유지하면서 각 시점에서 비조사구, 5 kGy 처리구, 5 kGy 재조사구순으로 높게 측정되어 방사선 처리 및 재조사에 의한 점도의 감소 현상을 볼 수 있었다. 이러한 현상은 기장(Panicum miliaceum) 분말에서도 동일하게 나타났다. 표면색깔의 경우 L및 a 값은 조사 및 재조사 여부에 따른 차이를 볼 수 없었으나 b값은 비조사구, 5 kGy 조사구, 5 kGy 재조사구 순으로 높게 측정되어 방사선 조사에 따라 황색화가 진행되는 것으로 나타났다. 미생물 농도는 비조사구의 경우 초기에 $10^2$CFU/g 이상 측정되었고 저장기간 동안 증가하였으며 조사구 및 재조사구에서는 저장 기간 중 측정되지 않았다. TBA value의 경우, 방사선조사구 및 재조사구일수록 높게 나타났으며 저장 기간동안 증가하였다. 따라서 방사선 조사 및 재조사처리를 함으로써 전분질 농산물의 점도 감소와 황색화의 진행 그리고 미생물 살균효과 및 지방질 산패 현상을 확인하였다.

"Master Plan of Cadastral Resurvey Project" aims to put the governmental budget of 1.3 trillion Won into the cadastral resurvey project until 2030 that reflects the preliminary feasibility study, conducted by government at 2012. The cadastral Resurvey, which takes 78.8% of the expenses in the project, has to take an critical role for earning the most effective results from the project. The cadastral confirmation surveying take up almost 13% of the project and is controlled under the areal SOC(Social Overhead Capital) projects in current "Master Plan of Cadastral Resurvey Project". Also, the affiliations of cadastral resurvey and linear SOC projects are expected to bring advanced results, although those are excluded from cadastral confirmation surveying. For linear SOC projects, the land division survey is conducted by using boundary stakes in boundary survey, while the cadastral resurvey is conducted within the SOC project area, after the completion of the project. In this study, we could conclude that cadastral resurvey results with the world geodetic system from boundary survey at the point of land division could be produced without the duplication of land division and cadastral resurvey. As a result, the expected benefits are 73,877 parcels and 4,078 million won, annually.

Since the "Special Law on Cadastral Resurvey" was enforced in 2012, the Cadastral Resurvey Project in South Korea has been promoted in earnest. However, it has been difficult to obtain the following items: a budget for the project, the establishment of land boundaries by increasing/decreasing the area of the parcels of land in the downtown area, the calculation of the adjustment fee, and the analysis of the relationship between the business owner and the landowner in regards to conflicts of opinion. The analysis of Japan's private-public boundary system, which is promoting the Cadastral Resurvey ahead of South Korea, should not attempt to determine complex interests, especially when they are pursuing consensus of the boundary setting portion of the Cadastral Resurvey Project. Therefore, this study shows that there is a need to reduce the number of stakeholders and promote them by using a step-by-step process. The introduction of cost-saving measures for the Cadastral Resurvey through a private-public boundary preliminary investigation is needed. This study suggested the following: link the precision road map construction business using MMS, introduce the preliminary research projects for the Cadastral Resurvey, and gather the important land survey information for the private-public boundary basic survey. In order to establish the utilization base, the researcher proposed linking the downtown area regeneration with the downtown area planning business.

After performing callback for nonresponses in sample survey, we present an estimator of regression form using an auxiliary variable and a variance estimator using replicate method. Parametric inference method of the response probability is also presented. We research an unbiased estimator of high efficiency for the population mean and a variance estimator with consistency under callback. We also prove the validity of the theory through the simulation.

The Cadastral Renovation is a National project to investigate and survey the registration of Cadastral Record and replace the existing Cadastral Record with a new Cadastral Record by digital, and to correct the registration of Cadastral Record if the registration of Cadastral Record does not match the actual status of the land. The Business Period generally takes about one year and six months to two years. The time required is getting longer due to problems that occur in the course of the Adjustment amount after the cadastral resurvey survey due to complex structure and internal conflict due to the interest between landowners. After Boundary Decision of the real boundary, the land area is confirmed by the landowners, and the cadastral office is to settle the Cadastral Renovation by calculating the Adjustment amount according to the confirmed area and the increase and decrease of the cadastral area. Therefore, the solution plan was suggested so that reasonable Adjustment amount can be applied through empirical research applied to the time of calculation of Adjustment amount and the method of calculation of Adjustment amount. The improvement method showed the expected effect that can lead the agreement with the landowner to the shortest period, and it was also possible to set the real boundary that meets the purpose of the Cadastral Renovation. This study suggests improvements in the method of calculating standard Adjustment amount, the method of imposing Adjustment amount, and the method of boundary adjustment that does not impose adjustment amount through the cadastral Renovation and parallel studies, and it is expected that the Cadastral Renovation will be completed by 2030.

정부에서는 사회 경제적으로 많은 문제를 발생시키고 있는 지적불부합지 문제를 해결하고자 지적재조사 사업을 계획하였으나 수 조원에 달할것으로 예상되는 막대한 사업비와 국민적인 이해부족으로 인하여 중단이 되었다. 이렇게 지적재조사 사업이 전면 중단된 상황에서 지적불부합을 효율적으로 해결하기 위해서는 현지 측량 방식에 기반하여 불부합지를 조사하고 정리하기보다는 현재 구축되어 있는 지적도 전산화 데이터와 GIS 관련 데이터 등을 최대한 활용하여 조사할 수 있는 새로운 방법론의 모색이 필요하다. 본 연구에서는 기 구축되어 있는 수치지적도와 수치지형도를 이용하여 지적불부합을 측정할 수 있는 방법론과 절차를 개발하였다. 그리고 모든 과정을 상용 GIS 소프트웨어를 이용하여 구현하였다. 방법론의 실험을 위해 실제 사례지역을 선정하여 적용하여본 결과 불부합을 정량적으로 조사하고 해석할 수 있는 가능성을 제시할 수 있었다.

The introduction of a world geodetic system for cadastral survey will be started the enactment of the law on survey, hydro-graphical examination and cadastre. However, the cadastral control points are not homogeneous and correspond with national control points because of various reasons. To cope with this problem, the 1,600 high accurate control points, which can be interlocked with national GPS control points, has selected from existing 20,000 cadastral control points. These selected control points were calculated as an accurate world geodetic system and it makes a homogeneous cadastral survey network. Through these measures, for the future carrying out national project, this study will be effectively contributed to establish the cadastral infrastructures for the Korea cadastral reform project.

Since 1910 the enactment of the Land Survey Act, Special Act on Cadastre Resurvey was enacted after about a century and the Surveying for the Cadastral Resurvey Project will be scheduled by 2030. The establishing boundaries occupies an important proportion in this project and the regulation on surveying for the cadastral resurvey provide specific examples of the criteria for it. This regulation can be set according to not only ground boundary and cadastral boundary, but also customary boundaries of the relevant region and boundaries agreed between landowners. However, there is no standard rule whether to accept the agreement boundary and can be abused some problems. In addition, there is a question about the subject that agreement between individuals on the public record managed by the nation. In this study, boundary agreed in cadastre related subject is examined in depth and improvement proposal about the problems. The research results can be established evaluation standard of competent authorities of the cadastral records and the Surveying for the Cadastral Resurvey Project will be progressed smoothly with effective use of land.

Korean government has constructed a nationwide cadastral map database through the cadastral map computerization project and also produced a variety of spatial data through the NGIS (National Geographic Information Systems) project. Under this circumstance, it is needed to set up the new automatic methodology that effectively solve cadastral non-coincidence problems by using various digital map data instead of expensive field survey methods. This study proposed a new automatic methodology for cadastral non-coincidence surveying and developed a prototype system as a proof of concept. Validation of this proposed method was done with some test areas. Results showed that this methodology could easily detect and assess both regional non-coincidence levels and cadastral map quadrangle non-coincidence levels. We expect that this new methodology can provide many benefits in planning and determining work priority of the forthcoming nationwide cadastral re-surveying project.

In this paper, a new method is proposed to remove the logical redundancy for the gate-level circuit optimization. In this method, only the fanout-branch signals in the circuits, not all the signals, are examined for redundancy. When a signal is determined to be nonredundant, other nonredundant signals are found out by the efficient procedure, using only the informations which are generated in the course of the redundancy-check. In order to avoid the re-examination of a signal for redudancy, a heuristic method is proposed to determine the redundancy-checking order of signals. The proposed method is heuristic, based on the VLSI test theory. It is much faster than other methods, since it does not reexamine a signal for redundancy.
