The primary objective of this paper is to develop an interactive computer graphic aided decision su, pp.rt system for the design of inspection plans for complex production systems. This research first develops a computer simulator, called Simulator for Inspection Systems(SIS), in order to represent the production system as a network model. The simulator elicits fundamental information about the system from the decision maker(DM) in an interactive manner. A decision su, pp.rt system is then proposed by combining SIS and Compromise Programming. The system simulates a set of possible inspection strategies implicitly, observes all the important measurements about the inspection system, and employs the compromise programming a, pp.oach to help the DM determine the best compromising allocation of inspection effort considering his/her preferences. Finally, the performance of the proposed system is evaluated using two test cases. The pros and cons of the system are also discussed.

Today ordinary consumers have the option of buying the products/services through Internet commerce, home shopping, or traditional commerce. This study compares the means-ends objective measures comprising the customer satisfaction with each type of commerce. Means objective variables consist of product variety, impulsive buying, comparison shopping, product information, and accuracy of transaction. Ends objective variables include convenience, safety, time saving, cost reduction, and shopping enjoyment. Results of data analysis indicate that ends objective variables are directly related with the behavioral intention of customers, and that each type of commerce has its own pros and cons which in turn provides the basis for differentiated customer satisfaction.

Terrestrial Laser Scanner and Airborne Laser Scanning is one of the state of art surveying equipments. So This study deals with the combined use of mobile TLS(Terrestrial Laser Scanner) with ALS(Airborne Laser Scanning) to extract shoreline's topography information. These two systems have their own pros and cons. Mobile TLS can capture the facades of a low story building along the shoreline fast and quickly. Meanwhile, Due to viewpoint restrictions of ALS data collection, the amount of detail, which is available for the building facades is very limited. Therefore, it is recommended that the co-registration and geo-referencing methods of both two should be developed and the application of both system for shoreline mapping also should be investigated.

A low speed wind tunnel test for the canard airplane model was conducted in KARI LSWT. To measure the required level of accuracy, the image system was applied for all elevator deflection and different canard incidence conditions. By doing so, the difference in aerodynamic characteristics between the forward swept and straight canards can be precisely evaluated, and the pros and cons of both canards arrangements can be discussed. Compared with both canard configurations at the same incidence angle setting, the straight canard has benefits in lift and drag, and the slope of pitching moment increases more moderately than the forward swept canard. The listed data and discussion would be useful to whom wants to design a canard airplane.

In this study, summary of past tilt-rotor concept development presented, and based on that, major pros and cons of tilt-rotor technology compared to other air-vehicle concept was presented. Also presented were major design features, considerations and sizing constraints of tilt-rotor configuration implemented to the development of Smart UAV. It is hoped that this paper be served to understand the tilt-rotor air-vehicle design and development.

We present our N-body simulation study on the disk galaxy warp formation via close encounters. Using a publicly available code Gadget2, we investigate morphological and kinematical structures of disk galaxies while the galaxies are undergoing fly-by encounters with adjacent dark matter halos. In this study, we find that warps can be excited by impulsive encounters and sustained for a few billion years. Most of the warps from the simulation show inclination angles that are comparable to the observations. The creation of warps, their inclination and their lifetimes are governed primarily by the following three parameters: the impact parameter (the minimum distance between two halos), the mass ratio between two galaxies, and the incoming angle of the intruder. We discuss pros and cons about our alternative scenario in comparison with existing explanations.

Mess removal, electrocoagulation, cryosurgery are conventional methods in the treatment of various oral mucosal diseases. However, there are several problems or complication during or after surgery using conventional tools. Recently, LASER gradually become useful tool in the surgery of oral mucosal diseases. Of the LASER, carbon dioxide-mediated LASER is widely used one. Carbon dioxide LASER has many advantages such as good bleeding control, decreased damage to adjacent tissue, decreased pain and swelling, reduced scar formation, even bacteriocidal effects. In this reports, the author describe pros and cons of LASER, especially focused on carbon dioxide, and shed light on the field of LASER application in treatment of various oral mucosal diseases.

Purpose: The purpose of this study is aimed to examine the Free Trade Agreement and its General Agreement on Trade in Services, especially, the healthcare service and the prospect of the system. Methods: This study was based on fourteen literature reviews from 2001 to 2014. Results: Free Trade Agreement and the General Agreement on Trade in Services were examined and Japan, China, and the United States's examples were shown. Healthcare market opening issues are the tendency of this era with the concept of globalization. Conclusion: This study highlights the tendency of healthcare market opening with all the pros and cons. The healthcare system along with the medical and nursing fields need to modify their system based on the globalization.

Coherence length (time) is a key parameter in many classical and quantum optical applications. Two interferometers – Michelson and Young’s double-slit – are used to characterize the temporal coherence of single photons emitted from single terrylene molecules. For quantitative analysis, a dispersion-related distortion in the interference pattern of a Michelson interferometer is carefully corrected by a simple dispersion compensation. Additionally, it has been demonstrated that Young’s interferometer can be used in temporal coherence studies at the single photon level with high accuracy. The pros and cons of the two systems are discussed. The measured coherence lengths in the two systems are consistent with one another under the self-interference interpretations.

The Outsourcing Industry has grown swift pace and evolved over time, and the Global IT Outsourcing market has shown signs of a steady growth. In the Korean company, however, IT Outsourcing is not active as that of the advanced countries and there is lack of literature to understand the characterristics of IT Outsourcing in the Korean company. This paper, therefore, analyze the outcomes surveying 65 compaanies in Korea to investigate how IT Outsourcing risk factors affects IT Outsourcing intention. Based on our literature reviews bassed on number of key articles, journals, and the focus group interviews, IT Outsourcing risk factors are proposed into four different domains: Transaction, Client, Vendor, Environment perspectives. It found that one factor(Vendor perspectives) is closely related to the IT Outsourcing intention of the Korean company. Finally, this paper analyzed the pros and cons of IT Outrcing offers a guide to the risk factors.
