The Chinese Architect Wangshu, who won the Pritzker Architecture Prize at 2012, is the first and only winner in China. This study focused on the expression of his unique architectural ideas. Especially with a high interest in Chinese traditional calligraphy and landscape painting, Wangshu tried to use its traditional features to form his own architectural way. First this study looked at the features of calligraphy and landscape painting. Second this research studied the expression of Wangshu's architectural practice in calligraphy's way. Lastly this study furthered study of Wangshu's architecture combined with landscape paintings' features. The results state these following. 1) For calligraphy, he used the "modular composition" of Chinese characters to architectural composition, which included architectural form and materials. The "similarities" and "space creation" of calligraphy are respectively applied to architectural spatial details and site planning. 2) For landscape painting, Wangshu borrows its elements to compose his architecture with "gardening consciousness". The "view method" of paintings was used to his architectural pedestrian flows, and Wangshu also based on the "space creation" of landscape painting to do architectural space design with creating the similar atmosphere.

A part definition must not only provide shape information of a nominal part but also contain non-shape information such as tolerances, surface roughness and material attributes. Although machining features are useful for suitable shape information for process reasoning in the CAPP, they need to be integrated with tolerance information for effective process planning. We develop the tolerance modeler that efficiently integrates machining features with tolerance information for feature-based CAPP It is based on the association of machining features, tolerance features. and tolerances Tolerance features, where tolerances are assigned, are classified into two types; one is the face that is a topological entity on a solid model and the other is the functional geometry that is not referenced to topological entities. The functional geometry is represented by using machining features All the data for representing tolerance information with machining features are stored completely and unambiguously in the independent tolerance structure. The developed tolerance modeler is implemented as a module of a comprehensive feature-based CAPP system.

For rational agricultural land use planning, it is quite necessary to get hold of land suitability precisely and to make decision on land use patterns accordingly. In the methodological viewpoint, objective and scientific evaluation techniques for land suitability classification should be supported for the systematic land use planning. As one of technical development approaches to rational land use planning, this study tried to frame a land suitability evaluation system for agricultural purposes. Evaluation unit is defined as a tract of land bounded by road, other land units and topographical features. And quantification theory was applied in the determination works of evaluation criteria. The administrative area of Namsa-myon(district), Yongin-si(city), Kyunggi-do(province) was selected for the case study. In order to check the feasibility of the evaluation system developed in the study, field check team, consisting of 2 government officers and 2 representative farmers, carried out evaluation works by observation on 148 sample land units, 10% of total 1,480 ones. Between estimated and observed results, there showed very good relationship of its multiple correlation coefficient, R=0.9467.

Generating a project network of a specific construction project is very time consuming and difficult task in the field. To effectiviely automate and support the planning process, we design a case-based project planning expert system inspired by the fact a human expert project planner uses previous cases for planning a new project. A construction project case consist of its specific characteristics and the corresponding project network (i.e. project plan). Using frame based representation. we represent the project features affecting the progress network and the entities composing the project plan such as the buildings, construction methods, WBS (work breakdown structure), activities, and resources. The project planning process runs through most similar case retrieval, case adaptation, and user requirement satisfaction. We represent the construction domain knowledge for each procedure using constraints and rules. We develop the methodology for constraint-based case adaption. Case adaptation process mainly consist of activity generation/deletion and predecence constraint satisfaction, for which we develop the dynamic constraint generation method and connect user-level requirement representation the system-level network modification knowledge. The methodology is being applied to the prototype for apartment construction project planning.

This paper addresses the integrated problem of process planning and scheduling in FMS (Flexible Manufacturing System). The integration of process planning and scheduling is important for an efficient utilization of manufacturing resources. In this paper, a new method using an artificial intelligent search technique, called asymmetric multileveled symbiotic evolutionary algorithm, is presented to handle the two functions at the same time. Efficient genetic representations and operator schemes are considered. While designing the schemes, we take into account the features specific to each of process planning and scheduling problems. The performance of the proposed algorithm is compared with those of a traditional hierarchical approach and existing evolutionary algorithms. The experimental results show that the proposed algorithm outperforms the compared algorithms.

The purpose of this paper is to establish an effective featured based inspection planning system for OMM(On-Machine Measurement) process. In this system, an effective inspection process planning is accomplished by determining the number of measuring points, their locations and probing paths using fuzzy logic, Hammersley method and TSP problem. Also, an effective collision-free algorithm Is proposed based on the EZ-map analysis. All the inspection planning processes are performed based on the defined inspection features those are derived from the CAD database. Proposed inspection planning method is simulated for the given sample wrokpieces, and the results are analyzed. The results show that the proposed method can be successfully implemented in real OMM process.

The latest urban planning is taking advantage of the city's spatiality, and its weight is increasing. The spatiality of the city extends to the three-dimensional air space, including the underground space and the surface space, and this is the relative location of land-use situations utilizing the characteristics of the feng shui geography. In this study, the urban planning of the Suwon Department and the construction process of the Suwon Hwaseong Fortress were analyzed based on the feng shui geography, using the topography and geographical features of Paldal Mountain as the center of the data. Natural-friendly urban planning is required to adapt to natural laws and to preserve and share the ecosystem while harmonizing with the surrounding environment.

Setup planning for machining processes is a part of fixture planning which is also a part of process planning. A setup of a part is defined as a group of features which are machined while the part is fixtured in one single fixture. Setup planning includes a number of tasks such as the selection of setup, sequence of setups and datum frame for each setup. Setup planning is an important function in fixture planning which must be able to support and to clamp a workpiece to prevent deflections caused by machining and clamping loads. This paper presents setup planning system using expert system approach(SPES) for prismatic parts which can be machined on vertical milling machine. SPES consists of preprocessing module and main processing module. Preprocessing module executes the conversion of feature data to frame type data and the determination of setups, and main processing module executes the determination of datum frame of each setup and sequance of setups. Preprocessing module is coded by C language and main processing module is a rule-based expert system using EXSYS pro. The performance of SPES is evaluated through case studies and the results show successful work except for operation sequence of machining holes. This is due to the limited rules for machining holes.

Recently, plans to revitalize rural areas in addition to farming are actively having been groped since given agricultural conditions destituted. One of the plan is the 'Rural Tourism' which to sell to urbanites by merchandising rural and pleasant characteristics possessed by rural areas. As a part of the rural-urban exchange, analyzed the features of the experience programs operated by each village by selecting 152 rural-mountain villages where is supporting and presented results by synthesizing above conclusion. The results acquired through such research are as following. Currently, villages operate mainly with the experience program related to general agricultural life styles by synthesizing special features of experience programs with high frequency in operations as the present status of the rural-mountain villages and showed negative trends dependant to the existing natural resources and easy in operations. Moreover, the operation of the experience which are expected to publicize the village and create large incomes were insufficient, analyzed not to be stimulate purchasing activities by lack of connections among experience programs and only simple staged experiences are mainly operated due to low operation frequency of experience programs which can be operated with special interests or professional characteristics.
