The Mobile robots are increasingly being used to perform tasks in unknown environments. The potential of robots to undertake such tasks lies in their ability to intelligently and efficiently search in an environment. An algorithm has been developed for robots which explore the environment to measure the physical properties (dust in this paper). While the robot is moving, it measures the amount of dust and registers the value in the corresponding grid cell. The robot moves from local maximum to local minimum, then to another local maximum, and repeats. To reach the local maximum or minimum, simple gradient following is used. Robust estimation of the gradient using perturbation/correlation, which is very effective when analytical solution is not available, is described. By introducing the probability of each grid cell, and considering the probability distribution, the robot doesn’t have to visit all the grid cells in the environment still providing fast and efficient sensing. The extended algorithm to coordinate multiple robots is presented with simulation results.

컨테이너 터미널에서는 효율적인 선적 작업을 위해 선박이 입항하기 전 선박정보를 통해 선적 계획을 수립한다. 하지만 실제 선박이 터미널에 입항하여 안벽에 접안후의 실제 적재 상태가 계획 시점에서의 적재상태와 다르거나, 사전에 수립된 계획이 실행 불가능한 경우 등의 상황이 발생한다. 이에 따라 기존에 수립했던 계획을 즉각적으로 재수정 해야 하며, 이를 위한 해법의 연구가 필요하게 되었다. 이점에 착안하여 본 연구에서는 위에서 언급한 예기치 못한 상황에 대해 정리하고, 상황에 맞는 합리적이고 즉각적으로 활용이 가능한 실시간 선적계획 모델을 제시하였다.

Value of rural amenity resources scattered in rural area is difficult to be assessed isolatedly. Rural Amenity Resources Map (RARM) is developed for assessing rural resources based on specific territory. In the developing process, knowledge based system is oriented because rural amenity is differed from personal feeling. Possible decision trees in RARM are developed in reviewing process of previous GIS based decision support systems, and information strategy planning is constructed for achieving goals such as rural tourism, down shifting, and rural investment.

The purpose of this study were to identify the different farming styles of red pepper growers, to describe their characteristics and to get some implications far planning the agricultural development strategy in the area. The researcher surveyed quantitative and qualitative data through interview with researcher developed questionnaires from selected 99 farmers in Eumsung county, Chungbuk province, Korea. The researcher found the low types of red pepper farming: 'red-pepper-centric middle farmers', 'diversified larger farmers', 'red-pepper-dependant small farmers', and 'small farmers for own use'. Based on the above findings, the researcher could derive some implications as follows. Firstly, the difference of market strategy and marketing efforts among the four farming styles should be regarded as important considerations when planning the agricultural development strategy in Emsung county. Secondly, the cooperatives' red pepper marketing strategies in Eumsung county were focused on the processed red pepper products sold at middle or low priced by big retailers in urban areas. Therefore, the cooperatives should change their view point of quality, if they want to initiate the planning process of 'the production and marketing high quality red pepper'. Thirdly, the major efforts of Eumsung county Agricultural Technology Center (ATC) made efforts on increasing the productivity of red pepper farming, however, the technologies recommended by the ATC for farmers required more cost and labour especially for 'red-pepper-dependant small farmers' and 'diversified large farmers'. The ATC should make efforts to find new technologies for helping 'red-pepper-dependant small farmers' to reduce the use of pesticides and 'diversified large farmers' to use the regional images effectively for marketing their hish quality red peppers.

This study aimed at derivation of planning factors and applicable planning factors of residential environment for the elderly in Korean rural village in the more detailed level.

최적화란 목적함수가 최대 또는 최소가 되도록 하는 결정변수를 찾아가는 절차이다. 기존의 많은 연구자들은 최적해의 효율적인 탐색과정에 집중한 반면 최적화의 시작점이라 할 수 있는 목적함수 구성을 위한 연구는 상대적으로 미진한 것이 사실이다. 따라서 본 연구에서는 국내외에서 빈번히 사용되고 있는 가중평균법을 사용하여 tradeoff를 고려한 목적함수와 절대우선순위를 위한 가중값을 적용한 목적함수를 구성하여 표본추계학적 동적계획법을 통해 산정한 최적운영률을

블록 내 이적이란 컨테이너를 선박에 싣는 적하 작업을 효율적으로 수행하기 위하여 유휴 시간에 여기저기에 흩어져 있는 대상 컨테이너들을 적하 순서에 맞춰 몇 개의 베이로 모으는 작업이다. 이적 작업을 가능한 일찍 완료하기 위해서는 블록 내의 설치된 여러 대의 트랜스퍼 크레인들을 모두 활용하는 것이 유리하지만, 이적 계획 수립 시 크레인들 간의 간섭을 효과적으로 고려하지 못하면 상당한 작업 지연이 발생할 수 있다. 특히, 상호 교차가 불가능한 크레인들을 이용하여 이적을 수행하고자 하는 경우에는 이러한 간섭에 의한 지연이 보다 빈번히 발생한다. 본 논문에서는 교차가 불가능한 크레인들 간의 간섭을 고려하여 개별 컨테이너를 취급할 크레인을 선정하고 작업 순서를 결정하는 휴리스틱을 제안한다. 시뮬레이션 실험 결과 본 제안 방안이 다양한 환경에서 간섭에 의한 지연을 효과적으로 줄일 수 있음을 확인하였다.

This study was carried out to establish the master plan of Hadong park, public park for a unit of town in Hadong county. It was divided into two parts: site analysis, and planning. The present situation was analyzed in historical, cultural, and natural(geographical, topographical, climate etc.) aspects. The planning was focused on a nature-oriented, facility-oriented, and health-oriented park that can be accessed easily by residents. The analyses and planning of this study are summarized as follows. This site was located on Gal-Ma hill(渴馬峰) in Hadong county. The area was 168.608㎡. In the site area, there were cultural properties. The slope was a little steep.

본 연구는 화물 운송 문제에 GIS 기법을 응용하여 화물의 수거 및 배송문제를 개선한 논문이다. 최근 국내 물류업체들은 인터넷을 기반으로 주문, 검색 및 화물의 추적 등을 온라인상에서 실행토록 하는 방법을 중시하게 되었다. 국내외 배송 관련 기업들은 빠른 서비스를 요 구하는 긴급주문의 비중이 커 가는 시장변환에 대처해서, 서비스 능력의 향상과 효율적인 차량관리를 위해서 GPS와 TRS 등의 정보통신기술을 이용하여, 기업의 배차업무를 개선하려고 노력하고 있다. 하지만 아직까지 배차 담당자의 의사결정을 지원할 수 있는 배차기법에 대한 연구는 거의 이루어지지 않고 있는 것이 현 실정이다, 본 연구에서는 GIS기반 하에서의 거리산정방법을 제안하고 이를 이용하여 차량운송 및 수거계획 알고리즘을 개발하였다. 또한 본 연구에서는 차량 및 화물정보를 GIS환경에서 실시간으로 조회해 볼 수 있도록 하였으며, 입출력자료와 차량 및 화물정보 조회결과를 GIS환경에서 구현하도록 하였다. 사용자들을 위하여 GUI-type 프로그램을 개발하고 실 예제를 통하여 Sample 출력을 보였다. 본 연구의 결과는 추후 약간의 수정 보완을 통하여 실제 물류센터에서의 운송계획 작성시 바로 적용할 수 있을 것이라고 판단된다.

Practically, it is very hard to investigate the rural villages in North Korea. The Korean rural village in Yanbian is proximate from North Korea and most of inhabitants of the village have been emigrated from Hamgyeong-Do and Pyeongan-Do. In this sense, it can be meaningful to study Korean villages in Yanbian is an alternative approach toward researches of North Korean rural villages. In this study, spatial characteristics of the Ryongsan village, Ryongjeong city was studied as a representative korean rural village in Yanbian. The Ryongsan village has been formed based on the traditional culture and custom of North Korea. The case of planning and design is provided through drawings of components for planning of rural villages based on the results of spatial characteristics analysis.

The purpose of this study is to develop a simulation model of rural road path for infrastructure of green-tourism and public service in rural areas. This study makes an objective function for moving cost minimization considering car travel time according to road characteristics, which can route the optimal shortest road paths between the center places and all rear villages, based on GIS coverages of road-village network for connecting between center places and rural villages as input data of the model. In order to verify the model algorithm, a homogeneous hexagonal network, assuming distribution of villages with same population density and equal distance between neighborhood villages on a level plane area, was tested to simulate the optimal paths between the selected center nodes and the other rear nodes, so that the test showed reasonable shortest paths and road intensity defined in this study. The model was also applied to the actual rural area, Ucheon-myun, which is located on Hoengsung-gun, Kangwon-do, with 72 rural villages, a center village (Uhang, 1st center place) in the area, a county conte. (Hoengsung-eup, 2nd center place), and a city (Wonju, 3rd center place), as upper settlement system. The three kinds of conte. place, Uhang, Hoengsung-eup, and Wonju, were considered as center places of three scenarios to simulate the optimal shortest paths between the centers and rural villages, respectively. The simulation results on the road-village network with road information about pavement and width of road show that several spans having high intensity of road are more important that the others, while some road spans have low intensity of road.

블록 내 이적이란 컨테이너를 선박에 싣는 적하 작업을 효율적으로 수행하기 위하여 하나의 장치장 블록 여기저기에 흩어져 있는 컨테이너들을 적하 순서에 맞춰 몇 개의 베이로 모으는 작업이다. 이전시 적하 순서를 고려하지 않고 단순히 컨테이너들을 모으기만 하면, 적하 작업 과정에서 보다 일찍 적하될 컨테이너를 반출하기 위하여 상단의 컨테이너들을 임시로 옮겨야 하는 재취급이 빈번히 발생할 수 있다. 이러한 재취급은 적하 작업의 효율을 저해하는 가장 중요한 요소 중의 하나이다. 본 논문에서는 휴리스틱을 이용하여 적하 작업 과정에서 재취급이 발생하지 않게 컨테이너들을 이적할 수 있는 컨테이너 이동 순서를 찾는 방안을 제안한다. 시뮬레이션을 통한 실험 결과 본 제안 방안이 다양한 환경에서 컨테이너 이동 순서를 실시간에 생성할 수 있음을 확인하였다.

The purpose of this study is to propose the principle of rural village planning process based on rural resources, differently space planning process(regional planning, village planning, urban planning etc). The importance of this planning process is resources planning, facility planning, program planning. So we planed rural villages - two rural traditional theme villages. The major findings of this planning were as follows; First, we have to consider economic value of rural resources. Second, resources were used differently, according to village conditions, though same it. It is important to apply value-added it. Third, in future we have to additional studies; environment planning factor, community participation, resources evaluation in this planning.
