  • Decision-makings or the related policies regarding domestic grape production heavily depends upon the known market price data and official statistics periodically announced by government, at national level. However, usual adaption of the 'simple means' from these data may bring seriously biased decision-makings when the original data are biased, especially when the data are not convinced to be normal distributions to decision makers. In this regards, this study employs Monte Carlo simulation technique to overcome the limitations, based on the decision makers' subjective assumptions on the known data, and, tries to come up with flexible range of business information regarding grape-producing farm income. The approach used in this study also provides possibility that it may be useful when adapting subjective assumptions from various statistical distributions.

  • The traditional theories of games are based on an assumption that the payoffs have a single dimension. In reality, any alternative is likely to imply more than one payoff. This paper deals with the game against nature with vector payoffs. The purpose of this paper is to develop methods for finding the practical optimal strategy in the game against nature with vector payoffs. Under the assumption that a prior probability over the stats of nature is given, this paper shows that a practical optimal strategy in this game can be obtained by applying a entropy method in order to assess the payoff weight and by employing the concept of compromise solutions in order to reduce the non-dominated solutions. When subjective payoff weights are unknown as well as known, these methods can be used. A numerical example is given.

  • BMA, which is generally adopted in low bit-rate motion-compensated coding, performs properly under an assumption of rigid-body motion of moving objects. Since, however, the assumption can not be held in practical coding , the prediction errors with low correlation are generated. For effective transform codings of the interframe prediction errors, we propose a new transform coding technique which decomposes the prediction errors into two sources and then transforms them with DCT and WHT consecutively. The performance of the proposed algorithm is compared to those of the two conventional algorithms in terms of bit rate and subjective image quality.

  • The paper investigates the factors that affect the decision of young Chinese consumers to buy high-end cosmetics. The study is based on the responses obtained by questionnaires from 400 respondents in Guangzhou, China. The information was collected and classified on the basis of gender, occupation, age and education in order to understand the main characteristics of the sample in a better way. The purposive, convenient and quota sampling techniques of non-probability sampling method were used. Besides this, the predictive test was carried out with 30 respondents to ensure the reliability and validity of the questionnaires. The data was put to descriptive statistical analysis and multiple regression analysis in order to verify the hypotheses. The data revealed that, while brand awareness does not affect the consumer attitude about the high-end cosmetics, other factors like product involvement, perceived quality, subjective norm, and word-of-mouth have significant effect on consumer's attitude and consumers' intention about high-end cosmetics. The findings of the study show that subjective norm, perceived value, word-of-mouth, and consumer attitude of cosmetic products highly affect consumers purchase intention of high-end cosmetic products. The research paper helps to form concrete and effective marketing strategy based on various aspects of consumer behavior for high-end cosmetics in China.

  • 1. Objectives This study was purposed to find Dong's thoughts about the eight items of the "The Great Learning(Ta hsueh)" 2. Methods It was researched through comparative and overall study on the Dong-mu's thoughts in "Gyukchigo(格致藁)" 3. Results (1) Dongmu reinterpreted the eight items of the "The Great Learning(Ta hsueh)" as the relations between the subject and the object from the ontologic assumption of Affairs Mind Body Objects as the principle of existence and correlation, summarized into four categories, and classified into the individual and subjective affairs, and the universal and objective affairs. The four categories of the eight items of the "The Great Learning(Ta hsueh)" are correlated with the individual and the universal ethics of behavior, and connected with the element for overcoming the individual inclination of mind and wickedness. (2) After the individual and subjective human was established, the eight items of the "The Great Learning(Ta hsueh)" were classified into two categories, and coupled up with each two items('Being sincere in their thoughts' with 'Extending to the utmost their knowledge', 'Rectifying their hearts' with 'Investigating things', 'Cultivating their persons' with 'Illustrating illustrious virtue throughout the kingdom', 'Regulating their families' with 'Ordering their own states'). Being based on this, 'Being sincere in their thoughts', 'Rectifying their hearts', 'Cultivating their persons' and 'Regulating their families' were understood as four individual and subjective human-basic-essential activity. Especially, mind, heart, body and family(power) were regarded as the four basic element in human existence and activity, and in correlation with universe and society, set up as the subjective element in Dongmu's epistemology, theory of nature and emotion, theory of morality and theory of moral cultivation.

  • The attempts to explain the criterion of art criticism can be divided into three directions. The first is that there is a universal criterion of criticism. The second is that criticism is a subjective impression of each critic. Therefore, there is no universal criterion beyond a subjective impression. The third is that denies both claims. It tries to and the objective criterion which is neither universal nor subjective. In this paper, I will see how John Dewey criticizes the first two theories and holds the third theory. Dewey's denial of the first theory can be seen in his view of the judical criticism. The judical criticism claims that art criticism can be made on the universal criterion, as judical decision can be made on the general rule supposed to be applicable to all cases. But Dewey claims that the judical criticism cannot explain what makes the artist the 'masters'. Defining art as an experience, Dewey claims that art is a process of doing and undergoing, and that art is essentially an interactive activity between men and his environment As environment changes, the experience of the environment also changes. So art should accept the possibility of new experience. But, since the judical criticism advocates of the universal criterion which cannot allow the changeability, Dewey denies it. On the other hand, Dewey's denial of the second theory can be seen in his view of the impressionist criticism. The impressionist criticism claims that criticism is to clarify the impression which is consisted of feeling and imagery the art object evokes. To this claim, Dewey replies that to clarify an impression is to analyze it, and analysis can proceed only by going beyond the impression to the judgement. As we have seen so far, Dewey has denied the judical criticism that there is a universal criterion supposed to be applicable to all criticism. He has also denied the impressionist criticism that there are only subjective responses to the art object, and hence that there is no criterion of criticism at all. For Dewey, these two criticism are based on the same false assumption of the criterion, although their conclusions are different from each other. Both the judical and impressionist criticism failed to realize the difference between the meaning of the criterion as applied in measurement and as used in criticism. Criticizing of these two views of criticism, Dewey claims that there is an objective criterion which is neither universal nor subjective. Art criticism is objective in tv#o senses, i. e., in the first sense that it can be judged by the properties of the art object and in the second sense that it can be verified by the communities of the critics.

  • 영상의 유사성에 대한 사용자의 주관적인지를 학습하는 방법으로 relevance feedback 기술이 사용되며, 최근 들어 이에 대한 관심이 높아지고 있다. 대부분의 relevance feedback기술은 영상 유사성을 측정하는데 사용되는 특징이 서로 독립적이라는 가정하고 있으나, 이러한 가정은 유사성 판단을 모델링 하는데 있어서 상당한 제약을 두는 것이다. 이 논문에서는. 퍼지 측정과 Choquet 적분을 이용하여, 유사성 판단에 대한 보다 나은 모델링 방법을 제안하고, 이를 이용한 relevance feedback 알고리즘을 제안한다. 실험결과를 통하여, 기존의 가중치 평균 방식에 의한 relevance feedback보다 제안된 방식이 우수함을 보인다.

  • Developing a new commercial product, it is need to connect the end users demand of quality to the industrial technology of company. For this reason, this study is to build up the users demand for the imminent marketing product of a certain company by Analytic Hierarchy Process, analyze quantitatively users subjective thoughts collected by Group Consensus, calculate the added-value of users demands and verify the consistency of users opinions by consistency-exponential-calculation. The added value obtained by this method is substituted into a user-demand item of Quality Function Deployment. And, the technical characteristic data transferred from the extracted essential factor for developing and manufacturing a new product is substituted into a technical characteristic item of QFD. The faculty of quality is firstly finished by this procedure. But, because the relation a technical characterization with users demand do not be known in new product, Wassermans method was introduced for the correlation users demand with technology and for the processing and marketing of a new product. The all assumption on this thesis was based on the reliable real data of a certain company.

  • In this study, we will present a knowledge-based consulting system, called THYCONS, for diagnosing thyroid disorders. It has been developed to make the knowledge and expertise of the human expert more widely available, therefore achieving a high-quality diagnosis. Frames will be used to represent the medical knowledge of thyroid disorders, and several rules are attached in each slot of a frame. The uncertainty of diagnostic processes is manipulated by the subjective Bayesian method under the assumption that the pieces of evidence are conditionally independent. Searching for the group of diagnostic tests to be carried out and their optimum sequences will be established in order to infer a more correct diagnosis on the basis of maximum information gain with cost and time restrictions. Additionally. differential diagnosis will be carried out based on the information gained.
