In order to give back-to-farm residents the stable settlement environment in the rural area, the 'community village' is desirable as the village type and its village planning guideline should be supported as well. The purpose of this study was to develop a guideline for the planning of back-to-farm community village in the living and social environmental aspects, based on the comprehensive comparative analysis about items that field survey and literature suggested. The guideline for the living environment was developed for 6 items; village structure(adequate size, lot, outer space for household), village landscape(allocation, space composition), road system and transportation(parking lot in village, placement of bus stops, village trail, public transportation, road and pedestrian system), common living facilities and common space(number, size, location & placement, plan type, planning type of common facilities), transfer space, individual housing(type, size, planning type). The guideline for the social environment was developed for 3 items; village making and establishment(resident participation type, resident participation tool, residents' construction participation) and resident education in the course of planning, resident participation(gathering resident opinion, decision making, composition of construction committee, community newsletter).

For the Simultaneous Localization and Mapping (SLAM) problem, a different path results in different SLAM results. Usually, SLAM follows a trail of input data. Active SLAM, which determines where to sense for the next step, can suggest a better path for a better SLAM result during the data acquisition step. In this paper, we will use reinforcement learning to find where to perceive. By assigning entire target area coverage to a goal and uncertainty as a negative reward, the reinforcement learning network finds an optimal path to minimize trajectory uncertainty and maximize map coverage. However, most active SLAM researches are performed in indoor or aerial environments where robots can move in every direction. In the urban environment, vehicles only can move following road structure and traffic rules. Graph structure can efficiently express road environment, considering crossroads and streets as nodes and edges, respectively. In this paper, we propose a novel method to find optimal SLAM path using graph structure and reinforcement learning technique.

Since Jeju Ollegil opened in September 2007 and attracted the sensation of popularity throughout the country, the interest in 'Walking Trails' has increased, and the central ministries and the local governments composite and assign various 'Walking Trails'. Walking trails are not tours on which people go to see one spot and move to another spot by vehicle, but a long linear journey that leads people to see, to feel and to experience a region's landscape and culture while walking on the trail. 'Walking Trails' are efficient routes to discover and to use a former way and to link the various ecological regions' histories and cultural resources, so it is most important to select a route. Although the routes were selected by considering the various planning factors and giving each route a specified theme, some problems like the inconvenience of visitors caused by lack of facilities have occurred. After designation and construction of the trails, they were not properly evaluated by visitors. Therefore, it is the purpose of this study to suggest a better way to construct the trails by surveying visitor satisfaction and by analyzing the impact of planning a route on visitor satisfaction at Bukhansan Dulegil which was completed. For this study, with a questionnaire based on the literature review to identify the important planning factors for selecting a route, a survey was conducted on visitor satisfaction for each section and their intention to revisit and to recommend that trail. Based on the characteristics of each section that was identified in the field research, the trails were classified into five types and satisfaction of each type and each type was analyzed. In addition, analyzing the impact of planning factors on satisfaction, the impact of satisfaction on revisiting and recommending and visitors' perception of the theme, further improvement for better construction of the trail was presented. Satisfaction of sectors with strong natural elements was higher; 'walking comfort' was the highest planning factor affecting satisfaction. In addition, satisfaction was surveyed to have high influence on revisiting and recommending.

This Study attempted to comprehend difference between hiker and non-hiker's sense of place value at Namhansanseong Provincial Park. Especially, it was analyzed after visitors, who were divided into local residents & tourists and first time visitors & repeat visitors. Out of 600 visitors, who were over 19 years old, participated in the survey, 587 responses were used for data analysis. Consequently, Sense of place value at Namhansanseong Provincial Park were classified into three factors: Health Culture, Ecology Environment, and Connectedness. Hikers feel higher value on promotion of health, relaxation, environment than non-hikers. Among hikers, local residents feel higher value on ecology environment and connectedness than tourists. Among non-hikers, however, they have no difference between local residents and tourists, only repeat visitors and first time visitors. On this result, possibility of resident participation management on natural environment and trail was considered, and when the program, which is for raising cultural and traditional value, would develop, increasing number of repeat visitor should be considered as a high priority.

Despite all attempts to prevent fraud, it continues to be a major threat to industry and government. Traditionally, organizations have focused on fraud prevention rather than detection, to combat fraud. In this paper we present a role mining inspired approach to represent user behaviour in Enterprise Resource Planning (ERP) systems, primarily aimed at detecting opportunities to commit fraud or potentially suspicious activities. We have adapted an approach which uses set theory to create transaction profiles based on analysis of user activity records. Based on these transaction profiles, we propose a set of (1) anomaly types to detect potentially suspicious user behaviour, and (2) scenarios to identify inadequate segregation of duties in an ERP environment. In addition, we present two algorithms to construct a directed acyclic graph to represent relationships between transaction profiles. Experiments were conducted using a real dataset obtained from a teaching environment and a demonstration dataset, both using SAP R/3, presently the predominant ERP system. The results of this empirical research demonstrate the effectiveness of the proposed approach.

This study is to suggest the technique of ecological park to compatible mountain ecosystem near the urban in Woomyeonsan Urban Nature Park. It was proposed to differential technique from established ecological park focused on changing the cognition of nature, wetland ecosystem protection and restoration, and studying by served sound leisure program(nature observation and experience, etc.), in compatible mountain and urban forest near the Urban. Firstly, to achieve this aim, it was carried out delicated research and analysis that were the angle of inclination, trail, fauna, actual vegetation, bird and insect, and then to selected nature trail course and analysis capability through it.. In the basic concept and plan, firstly to make park aid mark and foundation mark, and then to establish the detail programs, nature observation program, management and organization program. This site where valley and mountain coexist was highly capable but whole site was very steep, so usable area is very narrow. To make Woomyeonsan nature ecological park escape from the established wetland type, ecological park and the park of event have to use nature material and introduce visitor. To establish it as the Nature Culture observation park and reflect on forest, valley of Woomyeonsan was divided into three display places; Nature ecosystem Zone, Meditation Zone, Nature Culture experience Zone and Nature Culture observation Center. For satisfying with ecological park aid mark and foundation mark, it was proposed to settle management plan for volunteer control and organization composition.

Visitor Impact Management (VIM) framework was developed in the United States to help recreation resources management to be more systematic and effective. It consists of a series of steps from examining problems and their causes to planning and implementing management strategies in order to solve the problems. This study was conducted to find management problems in Moodeung-san Provincial Park and suggest some alternatives based on VIM framework. Data were collected by on-site survey and a mail-back questionnaire in August of 1996 in Moodeung-san Provincial Park. Out of 1173, 519 respondents (44.2%) were used for the study. According to the study results, there were differences between users' perceptions about the present use of the park and the users' personal norms about the use of the park. That is, while 46% of the respondents considered the park should be used as 'the place for calm and meditiation,' only 19% of the respondents considered the park had been used as 'the place for calm and meditation.' Three social indicators (the number of users, the number of seeing others' inconsiderate behaviors, and the crime) and four ecological indicators (littering, human waste, trail conditions, and water quality of Moodeung-san valleys) were selected for the major managerial indicators of the study area. Generally, five out of 7 selected indicators were in worse conditions than the evaluative standards, Five indicators which were evaluated as in worse conditions include two social indicators (the number of users and the number of seeing others' inconsiderate behaviors) and three ecological indicators (littering, human waste and trail conditions). Two other indicators such as water quality of Moodeung-san valley and the crime were identified to be important for users' recreational experience. More concerns and systematic investigations on these indicators are needed. This study discussed some management strategies to solve the identified problems, and introduced how mangers may make use of these information for recreation resource menagement in the park.
