This study investigated consumers' perception of fruits and vegetables grown in smart farms to stimulate the sale of agricultural products grown in smart farms. To this end, a survey was conducted on 1,050 consumers. The main results are as follows. First, 58.6% of respondents knew about smart farms, and they perceived fruits and vegetables grown in smart farms as more valuable than those grown in conventional facilities. In the detailed values, values of safety and environmental damage reduction were perceived to be of greatest value among five values. Second, as a result of investigating the importance of smart farm cultivation information in comparison with price, the most respondents emphasized both smart farm cultivation information and price information, and smart farm cultivation information was compared with price information. Cases were investigated to be more important with slight differences. Third, 41.4% of respondents had the price premium payment intention for fruit and vegetables grown in smart farms. Fourth, as a result of analyzing variables affecting the premium intention, the higher the health value among five values was recognized and the more important the smart farm cultivation information was, the higher the premium payment intention was.

As designs that simulate man's five wits are important, all five senses used are complex. Tactil value by Bernard Berenson means that the object in fine art makes the spectator feel like his or her finger is touching something, although the spectator is distant from the art piece. Especially as costumes have a relationship with the flexible skin and moving body, tactile modality and tactile value is more important. In order to analyze how Madeleine Vionnet realized a new femininity through the application of the principal of tactile value to dress design and in order to define tactile value in the field of fashion, this study examines the theory of tactile value, sculpture, painting, contemporary art, and product design as well as the design of Madeleine Vionnet from 1925 to 1937 because she was in the fashion business enlarging dress shops in New york during this period. The shape of Madeleine Vionnet's dresses made the concealed body alive through organic curves pressed against the body from cuts and dissections based on the anatomy of a supple body with curves and movement. In the garments, soft physical characteristics or the glossy touch of silk or pile textile imitated smooth skin while colors similar to a woman's eye, hair, and skin color continue the impression of the dress extending to the body through these design elements, Madeleine Vionnet's dresses reinforce the will to touch female body hidden under the dress by tactile values, not by the body's modification or visual exposure.

Forages are the most important feed resource for ruminants worldwide, whether fed as pastures, forage crops or conserved hay, silage or haylage. There is large variability in the quality of forages so measurement and prediction of feeding value and nutritive value are essential for high levels of production. Within a commercial animal production system, methods of prediction must be inexpensive and rapid. At least 50% of the variation in feeding value of forages is due to variation in voluntary feed intake. Identification of the factors that constrain voluntary feed intake allows these differences to be managed and exploited in forage selection. Constraints to intake have been predicted using combinations of metabolic and physical factors within the animal while simple measurements such as the energy required to shear the plant material are related to constraints to intake with some plant material. Animals respond to both pre- and post-ingestive feedback signals from forages. Pre-ingestive signals may play a role in intake with signals including taste, odour and texture together with learned aversions to nutrients or toxins (post-ingestive feedback signals). The challenge to forage evaluation is identification of the factors which are most important contributors to these feedback signals. Empirical models incorporating chemical composition are also widely used. The models tend to be useful within the ranges of the datasets used in their development but none can claim to have universal application. Mechanistic models are becoming increasingly complex and sophisticated and incorporate both feed characteristics and use of biochemical pathways within the animal. Improvement in utilisation through the deliberate selection of pasture plants for high feeding value appears to have potential and has been poorly exploited. Use of Near Infrared Reflectance Spectroscopy is a simple method that offers significant potential for the preliminary screening of plants with genetic differences in feeding value. Near Infrared Reflectance Spectroscopy will only be as reliable as the calibration sets from which the equations are generated.

Purpose The high-technology market shows characteristics of a highly interdependent network market in both supply-side and demand-side, compared to other markets. Particularly, for convergence products, connectivity with related elements, as well as characteristics of innovation itself, is relatively important to the extent that they combine functions provided by several devices into a single device. Therefore, this study aims to identify whether network externality exists in value and adoption of a convergence product and discover a source of network externality, if any. Design/methodology/approach: Through a preceding research analysis and a literature review, 'social influence' and 'network size' have been drawn as direct network elements. On the other hand, general (comprehensive) concept compatibilities including 'intra-technology compatibility', 'inter-technology compatibility' and 'complementary-technology compatibility' are regarded as indirect network elements. Findings: Major findings are as followed;- First, it is shown that the factors influencing on perceived value of a convergence products are 'social influence' and 'network size' as the direct network elements and 'complementary-compatibility' among indirect network elements. Second, it is also found that 'intra-technology compatibility', 'inter-technology compatibility', 'complementary-compatibility' and 'perceived value' have significant effects on adoption of a convergence product. Particularly, it is known that 'complementary-compatibility' is an important source of network externality as it plays a decisive role in value judgment and has significant effects on perceived value. It is worthwhile to notice that this study comprehensively explains effects of network on high-tech products by structuring comparability as a multi-dimensional concept, as well as direct network elements.

Recently, more and more firms are considering the adoption of RFID technology because it is expected to make process automation easier and has many different application areas. A review of existing studies about RFID adoption methodology shows that the most of the proposed methodologies are mainly based on economic evaluations. However, in the near future when the adoption and diffusion of RFID become major forces among business firms, it would surely have some limits to decide its adoption solely on the basis of economic considerations. In order for all the important strategic objectives to be considered during the major decision processes, it is necessary to make explicit what the decision makers really want to achieve from the RFID system. In this paper, we propose a general value model of RFID system which can provide an overall vision of all values RFID adoption may offer and a way to search and evaluate alternatives on the basis of these values. Especially, this model contains not only opportunities but also risks of RFID adoption so that a balanced consideration can be made. The model building process was essentially based on the 'value-focused thinking' approach proposed by R. Keeney. The proposed model is expected to provide insights about what to do in the process of introduction in order to maximize the potential benefits and minimize the negative risks. Referring to this value model, the important decisions would have greater chance to be based on a balanced consideration of opportunities and risks.

Value-at-Risk(VaR) is an important part of risk management in the financial industry. This paper present a VaR forecasting for financial time series based on the quantile regression for GARCH models recently developed by Lee and Noh (2009). The proposed VaR forecasting features the direct conditional quantile estimation for GARCH models that is well connected with the model parameters. Empirical performance is measured by several backtesting procedures, and is reported in comparison with existing methods using sample quantiles.

We study the existence of positive solutions of second order nonlinear separated boundary value problems of superlinear as well as sublinear type without imposing monotonicity restrictions on the problem. The type of problem investigated cannot be analyzed using the linearization about the trivial solution because either it does not exist (the sublinear case) or is trivial (the superlinear case). The results follow from a known fixed point theorem by noticing that the concavity of the solutions provides an important condition for the applicability of the fixed point result.
