The base of leisure air activities are consistently expanding and its demand is expected to increase attributed to GDP growth and people's interest in its activity. Utilizing Visual Flight Rule, light sport aircrafts and ultra-light aircrafts are not under the effect of air traffic control center, which resulted in passenger injury due to emergency landing for adverse weather conditions and technical issues after pulling into mountain area, ocean and even urban area. Such events encouraged safety consciousness toward leisure aircraft activities and developing a measure to prevent a recurrence of the accident. This research focuses on suggesting compositive system for preventive safety management system by providing user based Flight information service and operating effective system, necessary for leisure aircraft activities.

South Korea and Mongolia are both the member countries of the World Trade Organization, but neither was the country with FTA. Nowadays, South Korea widely concludes the FTA with other countries, and the trade area has extended toward the neighboring continents and seas. Mongolia is a country with smallest economic entity but large in area and with abundant underground resources. And it's a main strategic zone of Eurasia. After the disintegration of the Soviet Union, Mongolia began to turn to market economy, and eagerly made effort to open and reform. With the expanse of trade and economy cooperation between South Korea and Mongolia, Mongolia started its sea road expanding. And the south Korea went to inland to get the necessary resources. Both of them feed its needs and obtain its profits.

This paper introduces a correlation-based surface matching algorithm that can be used to reconstruct the surface topography of an object that is scanned from multiple overlapping regions by an AFM. The image matching technique is applied to two neighboring images intentionally overlapped with each other. To account for the inaccuracy of the coarse stage implemented in AFM, all the six axes including the rotational degrees of freedom are successively matched to maximize the correlation coefficient. The results show that the proposed 6-axes image matching method is useful for expanding the measurement range of AFM.

In this paper, we proposed a hybrid type robot that simultaneously surveillance and reconnaissance on the ground and in the air. It was possible to expand the surveillance and reconnaissance range by expanding the surveillance and reconnaissance area of the ground robot and quickly moving to the hidden area through the drone. First, ground robots go to mission areas through drones and perform surveillance and reconnaissance missions for urban warfare or mountainous areas. Second, drones move ground robots quickly. It transmits surveillance and reconnaissance images of ground robots to the control system and performs reconnaissance missions at the same time. Finally, in order to secure the interoperability of these hybrid robots, basic performance and environmental performance were verified. The evaluation method was tested and verified based on the KS standards.

This study was conducted for the purpose of deriving implications by observing the changing patterns and characteristics of the farmland reduction area in urban vicinity with Gimhae city, Gyeongsangnam-do as the subject. In order to achieve this goal, we first examined the problems and possibilities of farmland reduction area in urban vicinity through a theoretical review. Additionally, the characteristics of land use and community were examined for Gimhae city, Gyeongsangnam-do. The results of the study are summarized as follows. First, for 35 years from 1981 to 2015, Gimhae decreased $50.52km^2$ of farmland, which is about 17.4 times that of Yoido, and about 69.4% of the decreased farmland area. Second, the decrease in agricultural land has been expanding to the whole of Gimhae City from 1990 to 2010, and has been continuing since 2010 around dong-area. Third, in the farmland reduction area in urban vicinity, the number of settlements increases rapidly, but the aging population also increases. Fourth, the composition of the community is getting complicated with the change of the members. Taken together, it is necessary to manage the area efficiently because rapid change is present in the farmland reduction area in urban vicinity. Based on this, the implications are summarized as follows. First, there is a change in land use due to the reduction of farmland not designated as agricultural development region. Therefore, it is necessary to supplement the farmland-conversion standard. Second, despite the fact that land use management has been carried out, there have been problems such as uncontrolled development due to the development pressure beyond institutional management, and therefore it is necessary to improve the structural defects of the pertinent legal system. Fourth, while the traditional farming activities are decreasing with the decrease of agricultural land area, the increase in farms with secondary jobs and the urban-rural interchanges organization's efforts can lead to increased visits from outsiders that seek rural tourism and experiential learning.

The purpose of this study is to analyze the changing housing construction in Jeju-do which is composed of two cities(Jeju-si, Seogwipo-si). The number of indigenous population and migrating population of Jeju-do has been increasing every year because it has more beautiful scenery, interesting culture and a higher ratio of natural green area to urban area than other provinces(inland). More than 70% of population in Jeju-si is concentrated in dong-area. As a result, urban area and commercial area are expanding in entire Jeju-do. On the other hand, green area and non-urban area of Jeju-do are decreasing steadily. And there was a lot of changing during a short of time after 2010 because of internationalization and urban development etc.. This study is an analysis about the changing of housing in Jeju-do by statistical data. As a results of the analysis. I discovered that 1) The supply ratio of available housing in Jeju-do is higher than other inland cities in other parts of the country. 2) Housing constructing is influenced by moving-in and moving-out population. 3) There are more detached houses in Jeju-do than apartments. The opposite phenomenon occurs in other provinces (inland cities). However, the number of detached houses is gradually declining in Jeju-do since 2000. 4) Most detached homes in Jeju-do have an area of $60m^2{\sim}90m^2$. Most apartments have smaller areas than $60m^2{\sim}90m^2$. Seogwipo has homes with a larger area than Jeju-si. 5) The ratio of concrete structure houses is increasing at high speed because of constructing of apartment buildings, on the other hand, the ratio of brick structure house is decreasing gradually. Finally, Even though Jeju-do has different from housing culture of inland, it is changing slowly like inland housing types.

On the basis of 2017, the cremation rate in capital area was 89.0% which was much higher than the national average cremation rate(84.6%). Due to the short supply of cremation facilities in accordance with the increased number of cremation cases every year, the demand for cremation from the residents outside of the jurisdiction area with no cremation facilities was increased, so that the residents in the jurisdiction area had difficulties in using the Online Cremation Reservation Service in Funeral Information System. Thus, this study aims to make suggestions for policies as follows.First, on the basis of 2017, the demand-supply rate of cremation facilities in Gyeonggi-do was 139.4%, which means that the demand for cremation largely exceeds the ability to supply cremation. Therefore, first, in the level of Gyeonggi-do, the expanded supply of cremation facilities should be induced by carrying forward policies such as financial support to the basic local governments installing cremation facilities and expansion of incentives support to the residents of regions attracting cremation facilities. Second, it would be necessary for the central government to expansively conduct the support standard price and government subsidy rate(70%) for the new construction of cremation facilities and the establishment of cremation furnaces. Third, there should be some policies to decrease the inflow of residents outside of the jurisdiction area by raising the fee for using cremation facilities outside of the jurisdiction area of Seoul Metropolitan City and also expanding the application of a sliding scale of cremation hours.

The non-planned development of the rural area surrounding the Metropolitan area has become a social problem. The land development program until now has an aspect of not combining the spacial plan and the environmental plan. The land use and city development system based on development should change into a form that combines developing the area and conserving the environment. Therefore, this research attempts to compare the results of the overlay analysis and the gravity matrix which are ways to evaluate the value land that has a high environmental conservation value. The research area is the town of Seonggeo-eup, Cheonan City, and the reason for selecting this area is because it is expected to be densely populated as a connected area to the Metropolitan and the development pressure, such as expanding the industrial area, is high due to convenient transportation. The environmental factors used in the research are the relative altitude, incline, age-class, natural degree of the ecology, classification of the land covering and the NDVI, and the research methods used are the overlay analysis of the GIS and the statistical method. The overlay analysis results showed level 1 13.2%, level 2 30.7%, level 3 47.4%, level 4 1.0%, level 5 2.4%, level 6 5.4% and so on. The gravity matrix was classified as level 1 27.0%, level 2 9.3%, level 3 58.2%, level 4 2.4%, level 5 2.3%, level 6 0.9% and so on. These results are more appropriate than current methods for plans that value the environment because the analyzed results of the gravity matrix have a tendency to highly condense the environmentally valuable area. Consequently, if the spacial and environmental plans combine and therefore expand the efficient use of the land in the current state where the nation's concern in environment is getting higher, it is thought that it will contribute highly on the development of the nation's life quality.

'Hanok(韓屋)' is the settlement that our ancestors completed for our lives through multiple verifications. Thus, there exists our nation's identity and a variety of tangible and intangible cultural elements are included in that settlement. Even though the dwelling planning of Hanok has been introduced by the modern trends of traditional style, it can not present the type of various space compositions according to the area and living characteristics and it shows a disparity in our real life through the introduction of the traditional Hanok's elements which are not fit into contemporary housing without filtration. To solve these problems, it must need to study on cases based on the present situation of the Hanok and analysis on characteristics. For the Hanok to meet the development of modern residence, there needs to study on many fields such as plan, complex, structure, material. Among them, this study intends to present the preliminary data for the improvement of Hanok's effectiveness by understanding and analyzing the current situation focusing on the natural transformation of Hanok which are currently building in Milyang Area. Also, as the second step of this study, this study attempts to analyze based on the present situation of New Hanok in Kyeongnam province by expanding the range.
