Remote Sensing Monitoring and Loss Estimated System of Flood Disaster based on GIS is an integrated system comprised flood disaster information receiving and collection, flood disaster simulation, and flood disaster estimation. When the system receives and collects remote sensing monitoring and conventional investigation information, the distributional features of flood disaster on space and time is obtained by means of image processing and information fusion. The economic loss of flood disaster can be classified into two pus: direct economic loss and indirect economic loss. The estimation of direct economic loss applies macroscopic economic analysis methods, i.e. applying Product (Industry and Agriculture Gross Product or Gross Domestic Product - GDP) or Unit Synthetic Economic Loss Index, direct economic loss can be estimated. Estimating indirect economic loss applies reduction coefficient methods with direct economic loss. The system can real-timely ascertains flood disaster and estimates flood Loss, so that the science basis fur decision-making of flood control and relieving disaster may be provided.

If the specifications of product. in general. art determined too wide. the precision of product becomes diminished. Otherwise it costs dearly to keep the precision. Therefore, It is realistic to consider various factors in determining specification of qualify characteristics TAGUCH Idefines quality of an object as "Quality is the loss that a product causes to society after being shipped. other than any losses caused by its intrinsic function". Particularly, to improve the performances of product TAGUCHI focuses his attention on the product design and process design which enable the functional characteristics of product to he robust to noises. In this paper, by the TAGUCHI's loss function, the characteristics which affect the variation of a product performance are classified into the scrappable characteristics and the reworkable characteristics when the target values of functional characteristics have been determined. And we will determine the tolerance of each characteristic which minimize the quality cost by the cost function which considers the economic factors and probability features of each characteristic.cteristic.

Despite manufacturers' effort to provide safe and reliable products, a number of product-related accidents occur all over the world resulting in much damage to property, personal injury and even loss of life. Considerable evidence indicates that some accidents arise from user negligence, but most are due to the design, manufacture, and distribution of unreasonably dangerous products when compared to their use. As a result, a tremendous number of product liability lawsuits have been filed, many times causing huge amount of financial damages to manufacturers. Furthermore, with increasing government regulation and growing power of consumer lobbies, manufacturers might be more exposed to product liability claims in the future than now. The objectives of this study are twofold: to provide a framework of future research on product liability and safety and to introduce a product safety policy. To accomplish these objectives, previous studies on product liability and safety were reviewed thoroughly. The product safety policy consists of two parts: (1) an engineering design strategy for reducing product-related risks and (2) a management program for a product liability loss prevention plan. The policy is essential to preventing manufacturers' liability exposure as well as designing a safer product.

본 연구에서는 소유효과(endowment effect)와 손실회피(loss aversion)성향에 기인한 판매자의 판매용의가격(willing-to-sell price: WTS)과 구매자의 지불용의가격(willing-to-pay price: WTP) 간의 차이에 관한 기존 연구를 최근 점점 더 소비자들이 경험하고 있는 새로운 유통경로인 온라인 경매라는 거래상황에서 재검증하였으며, 동시에 이러한 판매자와 구매자의 용의가격의 차이에 조절적 영향을 주는 요인으로, 이득(gain)과 손실(loss)에 대한 소비자들의 휴리스틱적인 성향과 관련된 기존 연구결과들을 바탕으로 하여, 제품 유형(product type)과 소비자가 가지고 있는 목적 지향성(goal orientation)이라는 추가적인 조절변수들의 효과를 살펴보았다. 실험결과, 기존연구와 마찬가지로 판매자들이 제시하는 용의가격(WTS)이 구매자들이 지불하고자 하는 용의가격(WTP)보다 높았으며, 이 두 가격의 차이는 거래되는 제품이 소비자의 입장에서 실용적인(utilitarian product) 가치를 갖는 제품일 때보다 쾌락적인(hedonic product) 가치를 갖는 제품일 때, 또한 거래에 참여한 소비자가 향상 목적(promotion goal)을 가지고 있을 때보다 예방 목적(prevention goal)을 가지고 있을 때 더욱 두드러지는 것으로 나타났다. 마지막으로, 본 연구결과의 이론적 및 실무적 시사점, 그리고 본 연구의 한계점 및 향후 연구방향에 대해서 논의하였다.

Purpose - This research aims to investigate how consumers' eco-friendly product choice ratio changes as the benefits of eco-friendly products are framed as (1) non-monetary benefits, (2) monetary gain integrated with the loss or (3) monetary gain segregated from the loss. Design/methodology/approach - A mixed-design, scenario-based choice experiment was conducted. A series of chi-square tests and residual analyses were conducted to analyze the data. Findings - When the monetary gain was larger or slightly smaller than the loss, the participants' eco-friendly product choice ratio was higher when the monetary gain was integrated with the loss than those in the other two conditions. When the monetary gain was significantly smaller than the loss, the participants' eco-friendly product choice ratio was lower when the monetary gain was integrated with the loss than those in the other conditions. The ratio did not differ between the latter two conditions. Research implications or Originality - This research shows that marketers should frame the benefits of eco-friendly products and their costs in different manners depending on the relative magnitudes of them. This research also complements the existing literature by comparing the effectiveness of non-monetary framing of eco-friendly product benefits with that of monetary framing following hedonic editing hypothesis.

The purpose of this study is to contribute reference material that provides insight into innovative process management that increases R&D output in commercializing new products. A model of a process from research to commercialization with the cumulative profit and loss curve is put forward and hypotheses related to success and failure are developed at the stages up to product launch. Seventeen large projects that have resulted in successful product launches have been examined from the initial research stage to commercialization. Prefect duration, standardized cumulative R&D expenditures and research resource concentration are analyzed in terms of statistical method and patterns in cumulative profit and loss curves after product sales, as well as the reasons for and other aspects of success/failure are investigated and analyzed. Consequently, valuable information on future management tasks has been obtained such as: (1) project duration differs depending on market sectors, product types and presence/absence of materials research (2) cumulative profit and loss curves can be categorized into four patterns (3) reasons for failure can be divided into technological and market problem categories and (4) these factors have an impact on product sales.

The present study provides a theoretical investigation on pioneering advantage based on reference dependence and loss aversion effect under prospect theory (Kahneman and Tversky, 1979). Behavioral explanations for pioneering advantage are provided from two different perspectives: one based on the prototypicality and the other on the utility uncertainty of the option. A pioneer brand creates the product category and makes a strong impression in customers' mind, and thus becomes the most representative or prototypical option of the category. In addition, the pioneer brand becomes the first option to be experienced by the majority of consumers in the product category, thus has the lowest level of utility uncertainty compared with the late movers. This study integrates the previous accounts for pioneering advantage by showing that consumers have higher preferences for the most prototypical and the least uncertain option based on loss aversion and reference dependence effect. This study suggests that firms should carefully analyze the consumers' loss aversion and perceived uncertainty and prototypicality of their products in order to develop effective market entry strategies.

The inhibitive effect of extracts of tamarind seeds and jackfruit seeds, curry leaves and henna leaves on corrosion of mild steel in 1M HCl solution have been studied by weight loss, potentiodynamic polarization and impedance measurements. Results obtained from the electrochemical techniques were in good agreement with weight loss results. From the weight loss data, the values of surface coverage ($\Theta$) and corrosion rate were calculated. The inhibition efficiency (IE) increased with increasing inhibitor concentration in 1M HCl solution. In all the cases the adsorption of the natural product extracts on the mild steel surface from 1M HCl follows the Langmuir adsorption isotherm relationship. Potentiodynamic polarization studies reveal the fact that all the four natural product extracts act as mixed type inhibitors. The decrease in the inhibition efficiency follows the order: Extracts of jackfruit seed>henna leaves>curry leaves>tamarind seed.
