  • The CARB in USA has demanded OBD functions that detect any deterioration of performance of OTS as well as a simple defect of OTS which can affect emission to meet the reinforced emission regulation. In this paper, OTS plausibility monitoring functions to meet the demand from CARB are discussed. The output from OTS is used for the diagnostics of the torque converter clutch stuck and the gear ratio synchronous error. It is possible to diagnose the abnormality of OTS function by considering the oil temperature characteristics which changes according to the driving status of vehicles. In result, the OBD regulations of the CARB can be satisfied obligating car manufacturer to detect any problems in OTS functions which can affect emissions.

  • 본 연구에서는 서로 다른 센서간의 영상 자료 융합을 위하여 Dempster-Shafer 기법을 제안하고 있다. 제안 된 Dempster-Shafer 기법은 불확실성의 최소 값을 대표하는 Belief 함수와 불확실성의 최대 값을 나타내는 Plausibility 함수를 사용한다. 이러한 두 함수의 차이는 Belief Interval 로 정의되며 이 값은 분석 대상에 존재하는 불확실 정도의 Measure 로 사용되며 Evidence Combination의 이론에 근거하여 서로 다른 센서간의 자료 융합이 가능하며 분류 결과로 클래스 맵 뿐 만 아니라 분류 결과에 대한 불확실성 정도를 나타내는 Belief 함수 값과 Plausibility 함수 값을 생성하여 분류 결과에 대한 보충적인 분석을 가능하게 하여 사용자의 분석 정확성을 증대 시킬 수 있다.

  • This study was peformed to investigate the use of preprocessed foods, satisfaction on using them, and the plausibility to extend its use in 134 elementary school foodservices in Incheon by questionnaire from December 11th to 28th in 1999. The percentages of school foodservices to purchase and use preprocessed foods were 99.06% in seed, 97.64% in fishes and poultry, 87.74% in meats, 57.55% in eggs, 55.32% in fresh vegetables, 51.42% in dried vegetables and 34.90% in beans. Dietitians were satisfied with having used preprocessed foods, and the reduction in cooking time was listed as the biggest advantage which could be obtained by using preprocessed foods. However, dietitians showed relatively negative attitudes for the plausibility to expand use of preprocessed foods.

  • The aim of this study is to propose the plausibility of Ship-repair industry brand in the global market. It has been argued that it is necessary to secure the identity of company because of the expansion of international market in the age of globalization. Authors of this paper have considered that the brand is a solution for global ship-repair industry's development in Busan region with focusing on the 5 elements (Salience, Imagery, Performance, Feeling, and Judgments) of Keller's brand equity block except Resonance. As a result, we presented the roles of company for securing the brand equity in ship-repair industry comparing with the elements of Keller's brand equity block. and implied the plausibility of global ship-repair industry's development. Especially, Securing the licences and certifications related to ship-repair industry is very important thing about the brand equity.

  • The quality assurance activities can detect the factors that affect the quality based on risk identification in the course of mass production. Risk identification is conducted with risk analysis, and the risk analysis method for the rotorcraft landing system is selected by failure mode effects analysis (FMEA). FMEA is a method that detects the factors that can affect the product quality by combining severity, occurrence, and detectability. The results of FMEA were prioritized using the risk priority number. On the other hand, these methods have certain shortcomings because the severity, occurrence, detectability are weighted equally. Dempster-Shafer evidence theory can conduct uncertainty analysis for the opinions with personal reflections and subjectivity. Based on the theory, the belief function and the plausibility function can be formed. Moreover, the functions can be utilized to evaluate the belief rate and credibility. The system is exposed to impact during take-off and landing. Therefore, experts should manage failure modes in the course of mass production. In this paper, FMEA based on the Dempster-Shafer evidence theory is discussed to perform risk analysis regarding the failure mode of the rotorcraft landing system. The failure priority was evaluated depending on the factor values. The results were derived using belief and plausibility function graphs.

  • Previous studies have reported that a plausible reference point has a greater anchoring effect than an extreme reference point. It is also known that the anchoring effect decreases when the individual's level of knowledge related to a given item is high. However, there has been no study examining the interaction of the plausibility of the reference point and the difficulty of the given question. Therefore, in this study, the effect of the reference plausibility and the difficulty of the questions on the anchoring effect were examined. The relationship between the response confidence and the anchoring effect was also examined. To do so, easy and difficult questions, plausible and extreme reference points were selected through preliminary research. The experiment was conducted following the 'standard anchoring task procedure'. As results, the extremity of the reference point and the difficulty of the question affected the size of the anchoring effect respectively. The difficulty of the question also affected the confidence of the response. Specifically, when a plausible reference point was presented and when a difficult question was presented, the anchoring effects were increased. In addition, the lower the confidence in one's performances, the greater the influence of the reference point when an extreme reference point was presented. These results show that the plausibility of the given reference point and the difficulty of the item have different effects on the magnitude of the anchoring effect and the degree of confidence. The results of this study support the attitude change perspective regarding the anchoring effect, which suggests that the anchoring effect varies depending on the characteristics of the reference point and the individual's knowledge.

  • This paper concerns different forms of poetic thinking, each of which attempts to investigating truth of being on the ground of its idiosyncratic feature. The horizon evoked via these practices, however, is the Absolute where any plausibility of communication be fundamentally blocked off. Poetry, for instance, relinquishes its semantic auto-referentiality in order to be expressive of something unsayable. Poetic diction, coming-into-being, and sound with no meaning are those three expressive modes that I will examine in terms of the so-called "poetic thinking."

  • This paper investigates simple gray level image enhancement technique based on Genetic Algorithms and Local Statistics. The task of GA is to adapt the parameters of local sliding masks over pixels, finding out the best parameters preserving the brightness and possibly preventing the creation of intensity artifacts in the local area of images. The algorithm is controlled by GA as to enhance the contrast and details in the images automatically according to an object fitness criterion. Results obtained in terms of subjective and objective evaluations, show the plausibility of the method suggested here.
