The purpose of this study aims to estimate consumption selection attribute, part-worth of organic instant rice through the use of conjoint analysis method. The conjoint analysis is to trace the development of consumer preference among multi-attribute alternatives. The selection attribute was including 4 factors preferred Type of rice, Capacity, Brand and payment price. For this research, a total of 192 questionnaires was collected of which 200 were completed. The research design was a full profile method by orthogonal design then 9 main profiles, 3 holdout sets were created. The results of this research were as follows. Consumers of organic instant rice are consider their importance of selection attributes was in order to price (25.87%), Type of rice (27.231%), Brand/Purchase channel (24.013%) and Capacity (18.494%). The findings of this study have identified 3 clusters for each experience visitors. Each cluster has a different and showed the relative importance or preference values for each accessible attribute of the segmentation.

This paper is concerned with the assessment of benefits from water quality improvements. The contingent valuation method (CVM) is employed to directly measure the value of the project for the improvement of the water pollution in the Kumgang area. The perceived value of the improved water quality is investigated by using questionnaires to those concerned living near water-polluted area. The questionnaire includes such questions as the amount to willingly pay, the motivation to pay, the reasons of rejecting the payment, and some socio-economic data. The results of the survey show that (1) non-use value of the environmental goods is perceived to be more important than use-value of the environmental goods; (2) "willingness to pay" for the improved water quality varies according to the degree of educational level. income level and ages; (3) the resistance to pay for the project comes from the "polluter's pay principle".

The number of organic farms are increasing in European countries during last 10 years. Most European governments are giving subsidies for organic farmers as well as converting organic farms from conventional farming method. The price level of most organic products are higher than price level of conventional products in general. However, there are certainly some market demand problems in organic products in some countries. Organic farms will be increased in 2005 and 2010 for 10∼20% of the total agricultural area in some European countries. Government subsidy payment is also increasing. Therefore, many farmers are going to change into organic farming method from conventional farming. However, there will be certainly some market demand problems in future because of national economic growth problems. At the same time, the quality of soil can be improved and status of health of urban consumers should be improved by consuming organic products.

The purpose of the study is to analyze the status and trend of less favored condition of fishing village in Korean island regions using the census of agriculture, forestry and fisheries. The less favored condition was measured as the difference in accessibility to major services and in fishery sales and resident infrastructure, applying the difference-in-difference method and propensity score matching method respectively. The result shows that access to major services has improved in island area between 2010 and 2015, implying that related policies such as the island comprehensive development project have been successful to some extent. However, some educational facilities, cultural facilities, and health facilities still have low inaccessibility and fishery sales are also significantly lower than in general area. This suggests that it is necessary to maintain related policies like the direct payment of fisheries.

Door to door service is a typical method for individual parcel deliveries. In the current delivery information system, a delivery person manually inputs the information of many delivery results, which causes inefficiency and difficulties of tracking deliveries. This study suggests an enhanced delivery information system which has the following two characteristics. Firstly, a tagged RFID(Radio Frequency Identification) transmits the delivery result information to the main server by just collecting RFID at a place of destination. Secondly, with the characteristics of rewritable method, the collected RFID is to be input new information and tagged to other parcels.

This study aims to analyze the risk factors caused by object damage and third-party damage loss in actual bridge construction based on past insurance premium payment data from major domestic insurers for bridge construction projects, and develop a quantitative loss prediction model. For the development of quantitative bridge construction loss model, the dependent variable was selected as the loss ratio, and the independent variable adopted 1) Technical factors: superstructure type, foundation type, construction method, and bridge length 2) Natural hazards: flood anf Typhoon, 3) Project information: total construction duration, total cost and ranking. Among the selected independent variables, superstructure type, construction method, and project period were shown to affect the ratio of bridge construction losses, while superstructure, foundation, flood and ranking were shown to affect the ratio of the third-party losses.

To Recently, the buckling is easy to happen a thin plate and High Tensile Steel is used at the structure so that it is wide. Especially, the buckling is becoming important design criteria in the ship structure to use especially the High Tensile Steel. Consequently, it is important that we grasp the conduct after the buckling behaviour accurately at the stability of the body of ship structure. In this study, examined closely about conduct and secondary buckling after initial buckling of thin plate structure which receive compressive load according to various kinds aspect ratio under simply supported condition that make by buckling formula in each payment in advance nile to place which is representative construction of hull. Analysis method is F.E.M by ANSYS and complicated nonlinear behaviour to analyze such as secondary buckling.

We investigate a practical method of calculating the impact of multiple domestic energy price change on the final demand, production, the export and import change, the change in the balance of payment of Korean economy. By combining an existing computable general equilibrium (CGE) model with the traditional input-output analysis with two additional assumptions on the price behavior, we provide a cost-effective method of analyzing the impact of multiple energy price changes on the domestic economy. The energy price shock we used in this paper is 0.127% increase weighted by the sectoral productions. The total impacts on price level and GDP are 1.258% and -0.940%, respectively. The impact on the total output (GDP and intermediate goods) is about -1.580%.

Currently using of card sway the our community together with developing industry, whether it is credit card or not any type of card, people have the card in the wallet. But these cards have a little problem like ragne of communication, data store term, and so on. So we adopt the bluetooth. Bluetooth has been watched on local wireless communication among the wireless communication method. Bluetooth has ranged from 10m to 100m for communication and dissipated low power. Besides bluetooth has the communication speed faster than communication method of other smart card. In this paper we designed the smart card which is automatically accounted without any payment.
