Rapid growth of the domestic economy caused a lot of the demand of land information. The land information system has to keep the records of the various data about land that includes its owner and usages. Also the system must present adequate results that have been accumulated upon a user's request. Since Korean Government enforces 'Law of National Land Usage and Management', the land in rural area was also tightly regulated as much as that in the urban area. In fact, when people wants to develop their land, then they realize that their land has many restrictions and regulations to use. Sometimes, they find many regulations and restrictions even in a parcel. Thus, many people quite often want to know all the laws, rules, regulations, and restrictions etc., whatever applicable on the land they are interested in. to use. The purpose of this paper is to show a legal service system that precisely presents all the related laws, regulations, and restrictions. for a piece of the land. It summarizes the search results on users' requests. It uses a knowledge-based expert system to figure out the users requests. In this paper, we designed the system architecture of the software, and implemented its prototype. The results on this system show more concise and user friendlier than those of the existing systems.

Hierarchical Task Network(HTN) planning, a typical planning method for effectively taking advantage of domain-specific control knowledge, has been widely used in complex real applications for a long time. However, it still lacks theoretical formalization and standardization, and so there are some differences among existing HTN planners in terms of principle and performance. In this paper, we present an effective way to translate a HTN planning domain specification into the corresponding standard PDDL specification. Its main advantage is to allow even many domain-independent classical planners to utilize domain-specific control knowledge contained in the HTN specifications. In this paper, we try our translation-based approach to three different domains such as Blocks World, Office Delivery, Hanoi Tower, and then conduct some experiments with a forward-chaining heuristic state-space planner, FF, to analyze the efficiency of our approach.

This study is to analyze correlation between Daniel Libeskind's architecture works and the effects as a series of music works be learning in youth and opera "Aron and Mose". The results showed that First, Libeskind created convergence of invisible line by borrowing the composition of freely flowed scales in score from his architecture. Second, he composed geometrical shapes of contrapuntal reiteration based on double tune in music structure, in other words forms of polyphonic proportion. and he expressed the geometrically, freely line rhythm by planning composition of multidimensional spaces, "Hybrid", planning the contrast of material, form by results of Intertextually combination between Architecture and Music. Third, he tried to express the pain, fear, anxiety, etc. of the past spatially, and constructed "the spaces of absence" on his works through inspiration from Arnold Sch$\ddot{o}$nberg's works.

The Land Use Suitability Assessment System was recently introduced by the Act on Planning and Utilization of the National Territory to use, manage, and develop the national territory, which integrated the National Land Use and Management Act and the Urban Planning Act. It provides a guideline for land use according to locational characteristics, usability, and developmental conditions of land in the vicinity. The database is constructed with LMIS cadastral data, posted land price data, and the data of related agencies such as the Korea Forest Service, the Ministry of Environment, and the Korea Water Resources Corporation etc. In this paper we describe accurate database construction method fur land use suitability assessment system as classifying and verifying errors deriving from database construction focused on Jinju city. Those data errors have the problems such as accuracy difference among the related agencies data, gap of data acquisition time, and non-consideration of latest updated data etc.

This study applies the methods proposed in this issue[1] to the 11 rainfall gauging stations of the Pyongchang area. Also, this study analyzes the error range of each interpolation method, and considers spatial distribution according to the number of gauging station. As the results, the linear programming methods shows the best minimum error. However, this method might be difficult to apply in the field because of need for programming. Comparatively, the inverse distance method shows more simple and accurate results than the linear programming one. The result of this study could contribute to the increase of accuracy for the filling of missing rainfall data.

This letter proposes a new blind fractionally spaced equalization (FSE). The conventional linear program (LP) FSE reduces the degree of freedom (DOF) by abandoning many equalization filter taps, which causes severe performance degradations. We use singular value decomposition (SVD) to obtain the signal subspace and to fully utilize all samples for performance improvement. The proposed scheme has similar performance with the nuclear norm minimization and has as low complexity as the LP equalizer.

To analyze the influence of variables of roadheaders, the linear cutting testing data of pick cutter were collected from the former literatures. The input factors were set up as uniaxial compressive strength, cutting depth, cutting spacing, attack angle, skew angle, and output factors were determined as specific energy, average cutting force, maximum cutting force, average vertical force, and maximum vertical force. After composing a table of the design of experiment (DOE). The contribution level of each factor was calculated by analysis of variance (ANOVA). As a result, the factors having greatest influence on cutting force and specific energy were uniaxial compressive strength and cutting spacing.

In every country, land has always been considered a particularly important resource and property. For Vietnam, a populous country with a relatively narrow cultivated land, the land is even more valuable because property is scarce in the process of building and developing the nation. Therefore, land administration is highly valued by the Vietnamese government and is a big priority. The study of land law and land policy in Vietnam from 1945 to present is a comprehensive view of the changes in land administration policy in Vietnam in each historical period. The study also provides the experiences and lessons learned in the field of land law and land administration in a country that has risen from the ashes of war, has accomplished reunification and has transformed from a centrally-planned economy, a feature of the communist economy, to a socialist-oriented market economy.

The non-mandatory guidance and illogical ordinance of local government generate complicated and vague regulations and procedures. These cause inconvenience in building administration, and give rise to unnecessary social and administrative expenses. The purpose of this study is to suggest the improvement of building administration by local government from an institutional point of view through the literature review and the specialist survey focusing on the problems arising from the building ordinances and non-mandatory guidance. The results of this study are as follows; In the first place, the connection between law and ordinance should be improved in a systematic, definitude manner and high-degree of completion. Second, the monitoring management system should be arranged in order to excavate and improve the non-mandatory guidance. Third, the effort should go into improving ability and disposition of building official. Fourth, it is necessary to materialize and clarify the regulatory contents and adjust them to fit the legal system. Lastly, it is important to reinforce incentives and procedures of verification in order to manage building ordinances of legal government's own free will. In order to improve of building administration by local government, it is necessary to make the structure of sustainable improvement and discuss not only institutional aspect but also elements of building administration in later study.

A seam-line determination algorithm is proposed to determine image border-line in mosaicing using the transformation of gray value differences and dynamic programming. Since visually good border-line is the one along which pixel differences are as small as possible, it can be determined in association with an optimal path finding algorithm. A well-known effective optimal path finding algorithm is the Dynamic Programming (DP). Direct application of the dynamic programming to the seam-line determination causes the distance effect, in which seam-line is affected by its length as well as the gray value difference. In this paper, an adaptive cost transform algorithm with which the distance effect is suppressed is proposed in order to utilize the dynamic programming on the transformed pixel difference space. Also, a figure of merit which is the summation of fixed number of the biggest pixel difference on the seam-line (SFBPD) is suggested as an evaluation measure of seamlines. The performance of the proposed algorithm has been tested in both quantitively and visually on various kinds of images.
