The structure of industry has changed from manufacturing economy to service industry economy. Especially when it comes to the standard of the countries with OECD membership, the ratio of the service industry regarding the total industry as well as the total working labor has been reaching to 70%. Considering these facts in mind, the productivity of service industry has become crucial day by day. Under this situation, this study aims to help seeking the solution to enhance the productivity by comparing and analyzing the productivity level of theme park industry in Korea with that of an advanced country. The service productivity of two companies that represent tour and leisure industry in Korea and Japan are compared and analyzed, and through this it suggests ways to improve service productivity of theme park industry in Korea.

Utility boiler operators seeking to gain the greatest economic advantage from their units are faced with three challenges, namely the obligatory light-up fuel costs, the additional expense of supplementary fuel firing should they wish to use a cheaper fuel that may be beyond the original burner manufacturer’s stability and combustion performance assurances and the immediate environmental impact of both. The novel use of plasma arc technology can provide a solution to these challenges. This paper introduces the work being undertaken through a joint collaboration between the EU, Kazahkstan and Russia in order to develop a tried and tested engineering methodology and a mathematical based application and sensitivity analysis approach for the design and optimisation stage of these plasma devices that, as a consequence, their assist in their universal introduction.

A control panel layout method based on the constraint satisfaction problem(CSP) technique was developed to generate an ergonomically sound panel design. This control panel layout method attempts to incorporate a variety of relevant ergonomic principles and design constrains, and generate an optimal or, at least, a "satisfactory" solution through the efficient search algorithm. The problem of seeking an ergonomically sound panel design should be viewed as a multiple criteria problem, and most of the design objectives should be understood as constraints. Hence, a CSP technique was employed in this study for dealing with the multi-constraiants layout problem. The efficient search algorithm using "preprocess" and "look ahead" procedures was developed to handle the vast amount of computational effort. In order to apply the CSP technique to the panel layout procedure, the ergonomic principles such as spatial compatibility, frequency-of- use, importance, functional grouping, and sequence-of-use were formalized as CSP terms. The effectiveness of the developed panel layout method was evaluated by example problems, and the results clearly showed that the generated layouts took various ergonomic design principles into account.esign principles into account.

In this paper, we consider an integrated inventory system where a single supplier purchases and processes raw materials in order to deliver finished goods to a single buyer for effective implementation of Just-In-Time purchasing. An integrated JIT lot-splitting model of facilitating multiple shipments in small lots is developed in a JIT purchasing environment. Also, an iterative solution procedure is developed to find the order quantity for the finished goods and raw materials, and the number of shipments between buyer and supplier. We show by example that the integrated policy adopted by both buyer and supplier in a cooperative manner can provide them a greater economic benefit than seeking the local optimal inventory policy independently.

The main aim of this research is centered on the relation between nature and humans, and is to study the ecological characteristics appearing both in Landscape Architecture, one of the currents of ecological architecture as the architectural solution on the relation between humans and nature, and in our traditional architecture. Through this study, we were able to see that our traditional architecture was influenced by our ancestor's view of nature, and that the foremost feature of our ancestor's view of nature on our traditional architecture is not conflicting with nature, but, instead it is complying with it through seeking harmony with nature. Also we could see that our ancestor's view of nature is similar to Landscape Architecture having come to the fore toward the tendency of modern ecological paradigm in that it is the representation seeking the organic view of nature pursuing the oneness among artificial structure, humans, and nature. That is, we could figure out that various ecological features appearing in modem Landscape Architecture had been represented for a long long time, in a natural fashion, In the manner of space makeup in our traditional architecture. This is the characteristic of our ecological thinking system understanding nature and humans at the same context, and it has come down not only to our everyday living but to the manner of architectural solutions as well. Through this research, we could reconsider the modern value of ecological architecture inherent in our traditional architecture.

Many of the bridge systems, including the girders and cross-beams, and concrete decks behave as the special orthotropic plates. Such systems with boundary conditions other than Navier or Levy solution types, or with irregular cross sections, analytical solution is very difficult to obtain. Numerical method for eigenvalue problems are also very much involved in seeking such a solution. A method of calculating the natural frequency corresponding to the first mode of vibration of beam and tower structures with irregular cross-sections was developed and reported by Kim in 1974. Recently, this method was extended to two dimensional problems including composite laminates, and has been applied to composite plates with shear deformation effects. In this paper, application of this method to the specially orthotropic laminated plates with various boundary condition is accomplished and the result of analysis is presented.

A prediction of streamflow based on multi-objective function is presented to check the performance of Probability Distributed Model(PDM) in Miho stream basin, Chungcheongbuk-do, Korea. PDM is a lumped conceptual rainfall runoff model which has been widely used for flood prevention activities in UK Environmental Agency. The Monte Carlo Analysis Toolkit(MCAT) is a numerical analysis tools based on population sampling, which allows evaluation of performance, identifiability, regional sensitivity and etc. PDM is calibrated for five model parameters by using MCAT. The results show that the performance of model parameters(cmax and k(q)) indicates high identifiability and the others obtain equifinality. In addition, the multi-objective function is applied to PDM for seeking suitable model parameters. The solution of the multi-objective function consists of the Pareto solution accounting to various trade-offs between the different objective functions considering properties of hydrograph. The result indicated the performance of model and simulated hydrograph are acceptable in terms on Nash Sutcliffe Effciency*(=0.035), FSB(=0.161), and FDBH(=0.809) to calibration periods, validation periods as well.
