본 논문에서는 영어 교육에 대한 사회적인 인식은 중요해지면서 다양한 방식의 영어공부와 학습모델들을 분석하고 오랫동안 가억이 가능한 학습시스템을 검토하였다. 그러나 영어의 기초가 되는 영어 단어의 공부법이 논리적인 근거 없이 강사의 인지도와 명성에 현혹되어 강사가 추천해 주는 공부 방법에 따라 잘못된 학습하는 경우가 대부분이다. 또한 사람마다 자기에게 맞는 학습법은 분명 존재할 것이다. 하지만 그 방법 외에 효과적인 다른 방법 또한 찾아 볼 수 있다. 헤르만 에빙하우스는 사람의 망각 연구한 결과 망각의 주기를 수치로 나타내었고, 라이트너는 플래시 카드를 박스에 넣어 복습을 반복하는 아날로그 장치를 만들어 복습의 효과를 연구하였다. 본 논문에서는 헤르만 에빙하우스의 망각 곡선 이론을 통해 효율적인 영어 단어 학습방법을 논리적으로 증명하고, 웹사이트를 사용한 라이트너 박스와 망각 곡선의 이론을 적용하여 망각의 주기에 따른 복습의 효과를 적용하여 결과적으로 사용자에게 접근성이 좋은 학습형 플랫폼을 제공하여 시간 대비 학습률이 좋은 시스템을 개발하고자 하였다.

This research estimated the variation of high school students' academic achievement by using the second to the fourth wave KEEP(Korea Education and Employment Panel) data. We explored the effects of study on academic achievement in proportion to self-regulated learning hours(except for school work and private tutoring). Analysis variables were self-directed learning(study) hours throughout senior high school and 9 grade academic achievement. We conducted Latent Growth Model(LGM) using KEEP panel data and program LISREL 8.8. Results showed that there were significant effects of self-regulated learning hours on the variation of senior high school students' academic achievement. Therefore, this was considered to be useful tips in getting the relation between students' learning and academic achievement.

The existing cadastral record cannot meet various and changing demands on land information, improve user convenience, and raise administrative efficiency. In addition, three-dimensional parcels, or spatial objects about three-dimensional space cannot be registered in the conventional cadastral record. The limitation of cadastral information based on two dimensions is quite stressing the necessity of three-dimensional cadastral record. The purpose of this study is to develop new limns of cadastral record model in order. In register three-dimensional positions and right relations of land and buildings. This study examined land cases where space was being three-dimensionally used. As the result, cadastral record models both separated by steps and integrated were developed, which can contain matters of land, buildings, and right registration about three-dimensional land parcels. Also, this study suggested a method where a building can be separately registered according to it's the superficies division.

The world geodetic system transformation of cadastral record have to minimize differences of boundary and area being in cadastral record according to transformation for that is direct connected with the land owner and property protection. However it is very difficult to accurately maintain the before and after transformation because coordinate transformation is generally using a mathematical conversion formula. At present, Helmert model by using 4-parameter is official coordinate transformation model for Cadastral Resurvey Project but scale factor is most sensitive to changes of area and relative position in the same parcel. In this study, it was proposed 3-parameter method using by scale factor fixing through the application of a Helmert in order to avoid changing the area difference and keeping the error within the tolerance range of the boundary which is related to the boundary point coordinate region.

This study reviewed the concept of land registration and analyzed the land registration system in UK, Australia, USA, the Netherlands, France and Sweden. Land registration is a process of registering physical information and rights related to land in the land register for protection and regulation of land rights, taxation and dispute resolution. The land registration systems in the six countries were mainly analyzed in terms of policy, land register, objects and systems. As a result, first, the establishment of the land registration master plan is of paramount importance for sustainable development of land registration systems. Second, land register needs to be improved for 4D land management and service. Third, reduction of period and improvement of work efficiency for the cadastral resurveying should be considered. Last, a plan to improve public services by linking the geospatial technology with the land registration system is need.

The boundaries of administrative districts are the basic system for the whole country and are closely related to the daily life of the residents. The administrative boundary of Korea is registered and managed in the cadastral study based on the intellectual study of cadastral system. There is a non-conforming land where the registration details of some cadastral studies do not match the actual situation of the land, and the cadastral rehabilitation project is implemented as a national project to create a new digital cadastral study. However, due to the cadastral rehabilitation project, there is an unreasonable parcel that the past administrative boundaries and newly registered boundaries are different from each other due to the registration of the past administrative boundaries for the newly registered cadastral studies. The purpose of this study is to identify the unreasonable administrative boundaries arising from the cadastral rehabilitation project and to identify problems in order to effectively manage the number of branches in terms of administrative and administrative efficiency in terms of registration and inhabitants management. It is expected that the legal system will be improved to legitimately control the boundary of the administrative district and to manage the boundaries of the administrative district accordingly and to provide the service and to solve the inconvenience of the nation.

Recently the coast is an important area in terms of spatial land use and natural environment conservation such as the expansion of a national land and the development of a coastal industrial zone in Korea. We can not provide a proper solution for a boundary determination raised by a land ownership dispute due to the insufficient coast land registration. We observed the status of the coast land registration and analyzed the problem through the investigation of the difference between a land title and a coast land in the study area. We selected the west coast with the big difference between the ebb and flow of the tide as the study area from a paper review, compared a cadastral line with a coast line and suggested a good guideline to solve the problem through understanding the status of the coast land title registration in Korea.

In this study, from a long-term perspective, we tried to find and present a plan to apply the results of transformation of cadastral coordinates to the world geodetic system in stages for cadastral records of graphical and digital cadastral area. There was a case where the difference in area before and after the transformation occurred irregularly in the transformation result of the cadastral coordinate system currently being promoted. In addition, it was found that transformation errors in cadastral non-coincidence areas occurred accumulatively, and the period for acquiring world geodetic results for cadastral reference points was insufficient. In order to solve this problem, the study proposed a plan to provide spatial information and related fields through advancement of continuous cadastral maps, etc. for maps that have been primarily transformed by the end of 2020. In addition, the maps used for cadastral surveying purposes were presented in the direction of applying them to cadastral records in numerical form in the long term to conform to the characteristics of graphical and digital cadastral area. It is expected that more stable cadastral record will be reflected by applying the world coordinate transformation performance by dividing the graphical and digital cadastral area.
