This study has been conducted in order to better understand a concrete and evidential disagreement that resulted from a conflict caused by the exploitation of folk village for tourism purposes. The purpose of this study was to analyze more realistically the phenomenon of the disagreement that originated from sightseeing in the hahoe folk villages by focusing on the problem between the ive groups as a potential and continual impediment to tourism. Two groups, residents and tourists, were compared in order to determine the underlying factors of the disagreement regarding exploitation of folk villages for tourism The two groups were clearly split: inhabitants of the village considered such exploitation negative, while tourists accepted it as positive. The two groups showed different understandings of the topic residents were in favor of the preservation of the physical resources, but against exposure of their private lives to the public, while tourists strongly respected the preservation of the resources of the village. A comparison of the common phenomena of disagreement between the two groups was performed, Variables that showed different responses between the two groups were loss of privacy of individual houses, verbal aggression and physical conflicts between the groups, and lack of administration. In most of the cases of disagreement, residents considered the disagreement phenomena to be more serious than tourists did except in one case: tourists placed a greater importance on the ugly view of the street market. Finally, in order to analyze the factors that impacted the level of the disagreement, a multiple regression analysis was conducted. Disagreement factors affecting tourists were verbal aggression between the groups, complaints about lodging and dining facilities, complaints about tourist facilities, and negligence of the administration in responding to requests. Among these, the most influential factor was verbal aggression between the groups. In fact, individual feelings between tourists and residents proved to be the biggest influence on the level of disagreement.

In recent years alternative navigation system such as a DBRN (Data-Base Referenced Navigation) system using geophysical information is getting attention in the military navigation systems in advanced countries. Specifically TRN (Terrain Referenced Navigation) algorithm research is important because TRN system is a practical DBRN application in South Korea at present time. This paper presents an integrated navigation algorithm that combines a linear profile-based TRN and INS (Inertial Navigation System). We propose a correlation analysis method between TRN performance and terrain roughness index. Then we propose a conditional position update scheme that utilizes the position output of the conventional linear profile type TRN depending on the terrain roughness index. Performance of the proposed algorithm is verified through Monte Carlo computer simulations using the actual terrain database. The results show that the TRN/INS integrated algorithm, even when the initial INS error is present, overcomes the shortcomings of linear profile-based TRN and improves navigation performance.
농촌 원주민과 귀농ㆍ귀촌인 간 갈등요인과 인식차이 분석

최근 농촌사회에서 귀농․귀촌인이 빠른 속도로 증가함에 따라 귀농ㆍ귀촌인과 농촌 원주민 간 갈등이 새로운 문제로 대두되고 있다. 이에 본 연구는 농촌 원주민과 귀농ㆍ귀촌인 사이에 발생하는 갈등에 초점을 두고 연구를 수행했다. 두 집단 간 갈등 요인을 도출하여, 갈등 요인에 대한 인식 차이를 밝힘으로써 향후 갈등관리에 대한 방향성을 고찰하였다. 조사방법으로서 선행연구와 심층 인터뷰를 통해 측정 변수를 도출하고, 농촌 원주민과 귀농ㆍ귀촌인을 대상으로 설문조사를 실시하였다. 분석 결과, 농촌 원주민이 유발하는 갈등 요인으로는 ‘농촌 원주민의 전통적ㆍ보수적 성향 및 귀농ㆍ귀촌인과의 문화 차이’, ‘농촌 원주민의 배타적 성향’, ‘농촌 원주민의 지나친 공동체 생활 특성’, 귀농ㆍ귀촌인이 유발하는 갈등 요인으로는 ‘귀농ㆍ귀촌인의 개인중심적 성향’, ‘귀농ㆍ귀촌인의 기존 농촌문화에 대한 무시’, ‘농촌사회 특성에 대한 이해 부족’ 요인으로 분류되었다. 갈등 요인에 대한 인식차이 중 농촌 원주민 유발 요인에 대해서 총 4개의 갈등 요인에 있어 농촌 원주민과 귀농ㆍ귀촌인 간 통계적으로 유의한 인식차이가 나타났다. 이를 통해 농촌사회 문화에 대한 귀농ㆍ귀촌인의 이해의 폭을 넓힐 수 있는 방안이 필요하며, 귀농ㆍ귀촌인이 농촌문화에 적응할 수 있는 발판이 필요함을 고찰하였다. 본 연구는 지금까지의 선행연구가 대부분 귀농ㆍ귀촌인을 중심으로 드러나는 갈등 요인과 현상을 다루고 있는 한계를 극복하기 위해 농촌 원주민과 귀농ㆍ귀촌인 간의 역동적인 관계로서 갈등 요인을 풀어나 갔다는 점에서 의의가 있다고 볼 수 있다. Recently, the conflict between the locals and the migrants (returnees and newcomers) to the countryside has arisen as a new problem with the rapidly increasing number of the migrants settling in the rural areas. This research focuses on the conflict between these two groups, examining the causes of the conflict as well as their different perceptions for a solution to the dispute. As for the research method, preliminary research was conducted and in-depth interviews were carried out to draw out the measuring variables, and surveys were done on both locals and migrants. It was discovered through the research that the causes of conflict created by the locals were their “cultural differences with the newcomers,” “adherence to the traditional values and conservatism,” “exclusiveness” and “overwhelming community spirit.” On the other hand, the causes from the migrants were their “self-centeredness,” “disdainful attitudes towards the rural community’s tradition,” and “lack of understanding of local culture.” For the causes of conflict created by the locals, both groups showed perceptual differences on four of the causes that were statistically meaningful. Through this, it was considered and concluded that a measure was required to help the migrants expand their understanding of the local society and culture and successfully blend into the community. This research is meaningful in that it explored the causes of the conflict to solve the problem by looking particularly at the dynamic relationship between the two groups which most previous research has missed out.

In this paper, we analyzed the navigation error of TERCOM (TErrain COntour Matching), which is TRN (Terram Referenced Navigation) batch processing, caused by scale factor error of radar altimeter and proved the possibility of false position fix when we use the TERCOM’s feature matching algorithm. Based on these, we proposed the new TRN batch processing algorithm using the slope measurements of terrain. The proposed technique measures on periodic changes in the slope of the terrain elevation profile, and these measurements are used in the feature matching algorithm. By using the slope of terrain data, the impact of scale factor errors can be compensated. By simulation, we verified improved outcome using this approach compared to the result using the conventional method.

To calculate the attitude in ARS(Attitude Reference System) using 3 gyros and 3 accelerometers, gyro drift must be compensated with accelerometer to avoid divergence of attitude error. Kalman filter is most popular method to integrate those two sensor outputs. In this paper, new Kalman filtering method is proposed for roll and pitch attitude estimation. New states are defined to make linear equation and algorithm for changing Kalman filter parameters is proposed to ignore disturbances of acceleration. This algorithm can be easily applied to low cost ARS
