토지 획득 문제(land acquisition problems)란 일련의 목적에 맞게 서로 인접하고 있는 최적의 토지 필지들을 찾는 것이다. 이 문제는 도시 및 지역 계획과 각종 구획 문제 등에서 사회적 활용도가 높은 분야로서, 공간적 요소인 인접성(contiguity)와 밀집도(compactness)는 중요한 제약요소로 다루어지고 있다. 그렇지만, 공간적 밀집도(spatial compactness)는 완벽한 측정방법이 존재하지 않고, 획득된 필지들의 둘레를 제거나, 모양을 측정하는 등의 여러 가지 방법으로 측정되고 있다. 그리하여 이 논문에서는 공간적 밀집도를 측정하는 새로운 방법을 제시하고자 한다. 인접한 토지 필지간의 내부적인 구조적 특징을 바탕으로 proximity degree라고 불리는 공간적 밀집도를 측정하는 최적화 연구모델(optimization model)을 발전시켰다. 일련의 실험을 통해 proximity degree에 따라 다양한 공간적 밀집도를 가진 모습을 확인할 수 있다.

Many of urban parks which have been designated for urban planning regulation are not well developed because the priority of investment is inferior to that of other public facilities. Park development is an urgent urban policy and it is hard to decide priority among parks. Therefore, it is necessary to evaluate the priority of park development. Thus the Analytic Hierarchy Process has been introduced because it is suitable for achieving objectivity by collecting the professional opinions. The goals of park development are evaluated by AHP method and the priorities among goals are conservation of natural environment, satisfying the residents' residents' needs, population density, regional pollution, land acquisition cost, ratio of greeneries and facilities within park areas. Priority of park development is decided by the standardization of each individual inventory data and considering of the professional opinions. Among the multi-attribute judgement methods, AHP method may be the most widely used. Despite the critical evaluations of the AHP, such as limitation of the nine-point scale and the rank reversal problem, application of AHP to decide the priority of park development is suitable for actual circumstances.

네트워크와 인터넷의 발달로 인해, 디지털 데이터의 보급과 확산이 쉽게 이루어지고 있다. 디지털 데이터는 손실없이 복제되고 보급될 수 있다는 장점이 있지만, 저작권 문제와 더불어 데이터의 무분별한 복제 문제가 발생하고 있다. 이러한 문제는 GIS에서도 발생하고 있다. GIS에서 데이터 획득을 위해 큰 비용을 지불하고 있는 반면에 데이터 소유권에 대한 보호 노력은 미흡한 실정이다. 현재 워터마킹은 데이터의 소유권을 보장해 줄 수 있는 좋은 방안으로 대두되고 있다. 이 논문에서는 워터마킹의 기본적인 정의를 설명하고 GIS에서 사용되는 raster 형식의 데이터와 vector 데이터에 대한 워터마킹 연구동향을 분석하여 보고자 한다.

Costal fisheries use small boat. The boats are frequently substituted with newly made boat or proper boat. When the boat which is substituted with another one after the fixed date for compensation is estimated for fisheries loss by public project, it is matter that which boat is the object for estimating average catch of fish. There are three ways in practical business. They are based on the date of spot probe, the date of conference for compensation and fixed date for compensation. In case of applying the first and the second ways, as the object of compensation is not fixed, there is problem that estimated result can be changed depending on changing boat tons even after the date of spot probe and the fixed date for compensation. Most of all, these ways are against Attached Form No.4 of the Enforcement Ordinance of Fisheries Law which regulate to calculate average catch of fish applying result of fishery for retroactively counted 3 years from the year before the year in which administrative measure day is. The other side, in applying boat tons based on the fixed date for compensation, estimated result of compensation will not change even boat substituted after the fixed date for compensation. Even though applying tons based on the fixed date for compensation, a problem still remains. If the boat get bigger after the fixed date for compensation, the then boat size must be applied for calculating average catch. But the boat get smaller, the changed boat size must be applied. Because changed small boat would be damaged less than the previous boat. And decrease in catch by changing boat into small one is not due to the project but due to the personal responsibility. This will help to increase objectivity and reliance on the compensation result. As the other objects are fixed based on the fixed date for compensation in the Act on Acquisition and Compensation of Land and Others for Public Project, it can be balanced with other object.

For agricultural water management, it is essential to establish the digital infrastructure data such as agricultural watershed, irrigated area and canal network in rural areas. Approximately 70,000 irrigation facilities in agricultural watershed, including reservoirs, pumping and draining stations, weirs, and tube wells have been installed in South Korea to enable the efficient management of agricultural water. The total length of irrigation and drainage canal network, important components of agricultural water supply, is 184,000 km. Major problem faced by irrigation facilities management is that these facilities are spread over an irrigated area at a low density and are difficult to access. In addition, the management of irrigation facilities suffers from missing or errors of spatial information and acquisition of limited range of data through direct survey. Therefore, it is necessary to establish and redefine accurate identification of irrigated areas and canal network using up-to-date high resolution images. In this study, previous existing data such as RIMS (Rural Infrastructure Management System), smart farm map, and land cover map were used to redefine irrigated area and canal network based on appropriate image data using satellite imagery, aerial imagery, and drone imagery. The results of the building the digital infrastructure in rural areas are expected to be utilized for efficient water allocation and planning, such as identifying areas of water shortage and monitoring spatiotemporal distribution of water supply by irrigated areas and irrigation canal network.

Under the provision of Article 63 of the Enforcement Regulation of the Act on Acquisition and Compensation of Land and Others for Public Project that is recently enacted and implemented (hereinafter referred to as the 'Lend Compensation Act') the compensation is required to make 'When the Actual Damage Amount' is confirmed for the damage in fishery affairs that is outside of the public project area. The compensation for fishery business on the indirect damage area has been excluded from the advance compensation subject to conflict with the existing laws on fishery business compensation with the controversy in method, procedure, time and others to confirm the actual damage amount, and it lacks the standard of calculation for detailed compensation on partial damages outside of business implementation area, which caused the ceaseless conflicts and straggles between the project implementation party and the victimized fishermen regarding the calculation method of damages, standard, compensation period and others. In particular, from the numerous problems in damage compensation in fishery on the indirect damage area, the most recent problem emerged is the issue on application method of damage period in calculating the damage compensation amount that the struggle has been deepened with the differences between the project implementation party and the victimized fishermen without the stipulation on the compensation, that caused the difficulties in carrying out the public project and other serious social problems. In this study, the reasonable application method for the damage period and the calculation plan of the damage amount for calculating the damages on fishery industry outside of the public project implementation zone that is not fully specified under the Land Compensation Act, and the indirect damage area is not influenced for the notification of project recognition, and the compensation to undertake with the damage in the fishery industry in project implementation area to have the nature of damage compensation, the right to engage in fishery industry has the perpetual nature of rights, the fishery damage compensation system of Japan also recognizes the perpetual right on fishery industry to calculate the compensation amount, and the compensation for damage amount has been exercised for the period of actual damage occurrence period regardless of remaining effective period for most of fishery permit and license for fishery compensation outside of the project implementation area following the recent various public projects as well as the development process of theory on fishery loss compensation that the calculation of damage amount on the fishery industry outside of the project implementation zone would be prudent to compensate by calculating the applicable damages during the period of actual damages, and by doing so, the 'just compensation' guaranteed under the Constitution may be materialized. Therefore, the calculation of the damages from the implementation of the public project shall consider the actual period of damages and the degree of damage from the public project to calculate by the income capitalization method, however, considering the equitable consideration with the compensation following the cancellation, it shall not exceed the compensation following the termination of the applicable fishery businesses. Furthermore, the calculation method of partial damage amount on the fishery business following the project implementation shall apply, depending on the period of damage occurrence, by (1) the case of calculating the future damage amount at the present time, and (2) calculating the damage from the past to the present time as well as the damage to be incurred later, by selecting the calculation method for damages following the damage occurrence type.
