This study aims to draw up a basic plan to construct an agricultural theme park in a farming city as a way of establishing its regional identity represented by "Three Whites". Sangju, Kyongsangbuk-do which is the subject area of the study has been well-known for "Three Whites (rice, silkworm cocoon and dried persimmon)." The purpose of the study is to take a closer look at the folk life and culture of Sangju and develop tourism resources to promote regional development and competitiveness of the city. This study was conducted in several phases in consideration of the characteristics of plan and design, on the basis of the theoretical review of agricultural tourism. In the first phase, planning conditions were analyzed as per development objectives. In the second phase, strategies and concepts were established for the theme park, based on which development methods were decided by phase and facility. Then, a preliminary review was conducted on functions and facilities to introduce to the theme park. In the third phase, a comprehensive plan was drawn up, which includes basic plans for respective parts. In consideration of the characteristics of the study, construction was not looked at in detail. The total size of land subject to the study is approx. $97,960m^2$, which was divided into four separate zones--Sambaek Cultural Experience Zone, Natural Observation & Experience Zone, Agricultural Life Experience Zone and other facilities zone--in order to connect facilities, functions and experience with the physical characteristics of the city, and separate space planning was conducted for each zone. The outcome of the study carries significance as an example of alternative tourism which considers regional characteristics, develops local resources and makes use of obsolete rural facilities, in what is called the eco-friendly development where nature and eco-system, landscape and culture, and recreation and leisure come together as one.

In every sectors of industry, the Business Process Reengineering(BPR) has been applied for taking competitive advantage under rapidly changing environment. A company adopting the BPR has begun to consider the introduction of Enterprise Resource Planning ERP systems. ERP systems can integrates many core activities of business, such as manufacturing management, human resource management, financial management, supply chain management by applying the best practices to facilitate a rapid decision-making, cost reductions, and organizational control. Unfortunately, however, many tentative risk factors are existed through each phase of the introduction of ERP systems. As a result, it can bring an enormous benefits to a company or it can be a disastrous for organization. Therefore, two critical questions regarding the introduction of ERP systems should be analyzed before actual introduction has happened. They are "how can ERP systems be introduced successfully\ulcorner" and "what are the critical success factors for each phase of introduction of ERP systems\ulcorner". Through this research, We studied and analyzed the characteristics of critical success factors requiring at each phase of the introduction of ERP systems by applying the questionnaire survey method. Finally, we suggest the list of barriers and critical success factors for each phase of introduction of ERP systems.tion of ERP systems.

The planning of part feeder and other manufacturing automation equipments is almost always underestimated. Planning ahead for those crucial pitfalls can permit steps to take to minimize heir impacts, especially if the problems can be discovered in the planning phase, not on the shop floor. Planning process is an engineering process, namely a series of trade-offs. The effective trade-offs in the shortest amount of time can be possible with the help of a computer-aided ngineering (CAE) technique. The main parts of CAE fur part feeder are database system of fabricated workpiece parts, part feeders, part feeder components. In this study, a planning process of part feeder is presented. Especially, a systematic analysis of workpiece parts and part feeders is performed for the design of databases of CAE system.

A necessity of increasing the energy efficiency of the buildings is rising due to global warming and high energy demands prices. Commissioning is an effective way to increase the energy efficiency of the building and reduce maintenance costs. In this study, a case study was conducted to derive the commissioning process of green building and propose management factors that can be used in domestic commissioning projects. The case was a university renovation project that received a LEED Glod certification and conducted the enhanced commissioning. The commissioning is divided into planning, design, construction, and post-construction phases. In the planning stage, commissioning company selection, commissioning goal setting, tasks and responsibilities for each subject are set. In the design phase, preparations are made for inspection and construction steps to prevent design errors. In the construction phase, problems are solved through periodic on-site inspections. In the post-construction phase, a final report with all the details of the commissioning will be created and future maintenance strategies will be proposed. Based on the findings of this study, it will be a basis for the management factors that can be used in the implementation of domestic commissioning projects.

Product Lifecycle Management (PLM) ranges from design concepts of products to disposal. In this paper, we focus on the production planning phase in PLM, which is related to process planning and production scheduling and so on. In this study, key decisions for the creation of production plans are defined as production-planning attributes. Production-planning attributes correlate complexly in production-planning problems. Traditionally, the production-planning problem splits sub-problems based on experiences, because of the complexity. In addition, the orders in which to solve each sub-problem are determined by priorities between sub-problems. However, such approaches make solution space over-restricted and make it difficult to find a better solution. We have proposed a representation of combinations of alternatives in production-planning attributes by using Zero-Suppressed Binary Decision Diagrams. The ZDD represents only feasible combinations of alternatives that satisfy constraints in the production planning. Moreover, we have developed a solution search method that solves production-planning problems with ZDDs. In this paper, we propose an approach for managing solution candidates by ZDDs' network for addressing larger production-planning problems. The network can be created by linkages of ZDDs that express constraints in individual sub-problems and between sub-problems. The benefit of this approach is that it represents solution space, satisfying whole constraints in the production planning. This case study shows that the validity of the proposed approach.

A minimum-time trajectory planning for two robot arms with designated paths and coordination is proposed. The problem considered in this paper is a subproblem of hierarchically decomposed trajectory planning approach for multiple robots : i) path planning, ii) coordination planning, iii) velocity planning. In coordination planning stage, coordination space, a specific form of configuration space, is constructed to determine collision region and collision-free region, and a collision-free coordination curve (CFCC) passing collision-free region is selected. In velocity planning stage, normal dynamic equations of the robots, described by joint angles, velocities and accelerations, are converted into simpler forms which are described by traveling distance along collision-free coordination curve. By utilizing maximum allowable torques and joint velocity limits, admissible range of velocity and acceleration along CFCC is derived, and a minimum-time velocity planning is calculated in phase plane. Also the planning algorithm itself is converted to simple numerical iterative calculation form based on the concept of neural optimization network, which gives a feasible approximate solution to this planning problem. To show the usefulness of proposed method, an example of trajectory planning for 2 SCARA type robots in common workspace is illustrated.

Recently, IT outsouricng has been one of the major concerns of many companies. This paper explores the relationship between information technology outsourcing risk factors and outsourcing performance. It is based upon a three-phase process utilizing IPO (Input-Process-Output) system. The first phase means the outsourcing planning risks t~at arise from overall environment of outsourcing, organizational refuse, and wrong contracts. The second phase implies outsourcing operational risks, which are occurred while out-sourcing perform and consist of organizational acceptances of outsourcing, partnership and hidden costs. The last phase is outsourcing performance based on four perspective of BSC(Blanced Scored Card). The survey was performed on the IT/IS firms, and the data was collected from 53 service receivers. The result of the analysis are as follows. First, Outsourcing planning risks positively affects the operational risks. Second, Outsourcing operational risks negatively affects the Outsourcing Performance.
