Spoken dialog tasks incur many errors including speech recognition errors, understanding errors, and even dialog management errors. These errors create a big gap between the user's intention and the system's understanding, which eventually results in a misinterpretation. To fill in the gap, people in human-to-human dialogs try to clarify the major causes of the misunderstanding to selectively correct them. This paper presents a method of clarification techniques to human-to-machine spoken dialog systems. We viewed the clarification dialog as a two-step problem-Belief confirmation and Clarification strategy establishment. To confirm the belief, we organized the clarification process into three systematic phases. In the belief confirmation phase, we consider the overall dialog system's processes including speech recognition, language understanding and semantic slot and value pairs for clarification dialog management. A clarification expert is developed for establishing clarification dialog strategy. In addition, we proposed a new design of plugging clarification dialog module in a given expert based dialog system. The experiment results demonstrate that the error verifiers effectively catch the word and utterance-level semantic errors and the clarification experts actually increase the dialog success rate and the dialog efficiency.

This study examines the effects of consumer beliefs for food certifications on the behavioral intentions and the behavioral intention biases to purchase the certified seafoods by a subjective probability model which is on the basis of the mathematical probability model and the covariance model. The food certifications used on this study are 'Organic foods', 'Traceability system of food products' and. 'HACCP'. The representative foods of fishery products on this study is seasoned laver. The current study showed the following results. First, consumers have more than two different beliefs each for all certifications which are the subjects of this study. The beliefs of the certifications have an impact on the consumers when they consider to buy the certified seafood products. Second, consumers try to persuade by themselves to ensure that their particular belief about the certification could lead to a purchase the seafood products. Consumer beliefs of the "environmentally friendly production" on the organic foods certification is an important factor as much as the "guarantee of food safety" belief making a positive purchasing behavior intentions(PBI) bias for the organic seafood products. Consumers also have a positive PBI bias for certified seafood products in all certifications as long as a certification is considered to "guarantee the transparency of the food distribution process" as its belief. 'Traceability system' was the only one which didn't generate a positive PBI bias from the belief of "guarantee of food safety" out of three certifications.

Purpose: This study was to examine the relationship of knowledge, health beliefs, and prevention behaviors of osteoporotic fracture in outpatients with osteoporosis. Methods: The subjects were 120 outpatients receiving osteoporosis treatment on K hospital in G city from Dec. 2007 to Feb. 2008. Questionnaires were collected and analyzed using the SPSS/WIN 12.0 program for descriptive statistics, and t-test, ANOVA, and Pearson correlation coefficient. Results: Subjects were treated for fracture about 28 months. The mean score of knowledge, health belief and prevention behaviors in subjects were $17.5{\pm}3.22$, $2.8{\pm}0.23$ and $2.8{\pm}0.38$ respectively. The score of health belief recorded the lowest point. However, the score of knowledge varied with general and disease-related characteristics of subjects. In contrast, the score of prevention behaviors did not showed any significant differences. Fracture prevention behavior in subjects showed rather higher relationship with the health belief system than the knowledge of fracture prevention. Conclusion: The present work suggested that education program for prevention behaviors of fracture should be developed to focus on altering the health belief system rather than the knowledge of osteoporotic fracture prevention. Furthermore, individual education program based on living circumstances and daily life habits should be also developed.

Purpose: The purpose of this study was to explore preserved belief system supporting Korean immigrant women's Taekyo practices and influencing factors while they observe the tradition within US sociocultural context. Methods: Leininger's exploratory focused ethnographic approach was used. Semi-structured in-depth interviews were conducted with purposive sample of sixteen Korean immigrant women who gave birth in the US within last 6 months. Researcher's observation and reflective field notes were also integrated into the interview data. Leininger and McFarland's four phases of ethnographic analysis guided data analysis process. Results: The perceived belief system supporting Taekyo practices included Taekyo as an enculturated Korean tradition, connecting parents with fetus, and positive impacts on fetal development. And Korean immigrant women's Taekyo practices were influenced by resources of information, woman's orientation toward Taekyo, pressure from local Korean community, and child order. Conclusion: The findings from this research would serve as an important knowledge base to expand US health care providers' understanding of Korean traditional Taekyo practices observed by Korean immigrant women's as important prenatal self-care practices. The findings could also aid in providing more patient-centered and culturally-tailored prenatal care plan to Korean immigrant by including Korean traditional belief system supporting Taekyo practices.

Little empirical study has been conducted concerning family resilience of family of children with disabilities. The purpose of this study is to examine the variables that may influence the level of family resilience and family resilience level of family of children with disabilities. This study used the sampled of 363 family of children with disabilities selected from 17 community rehabilitation centers. The measurement of family resilience composed of the base of Walsh(1998)'s theory. And using confirmatory factor analysis, it was confirmed that the scale has three factor such as belief system, organizational pattern and communication process. This study showed that using 5 points scale, mean of belief system is 3.62. And mean of organizational pattern is 3.38 and mean of communication process is 3.73. In identifying predictor of the family resilience, this study used variables from the following aspects: perspective of disability of children, intra-aspect of family, extra-aspect of family. Using Regression analysis, it was found that attitude of family of disability and spouse relationship influenced all sub-aspect of family resilience. Specially, helping of professional influenced belief system, accept of disability influenced organizational pattern. And positive expectation of family of disability influenced communication process. This finding give us significant practical implications for social work intervention & the direction of future research in family resilience.

신제품/서비스를 설계함에 있어 해당 제품 혹은 서비스가 제공하여야 할 기능을 선정하는 것(feature selection)은 디자이너의 매우 어려운 의사결정 문제이지만, 기존 방법론들은 특정 제품-서비스에 대한 사용자의 니즈를 효과적으로 파악하기에는 한계점이 있다. 특히 기존의 선호도 서베이를 통한 방법은 사용자의 멘탈모델에 대한 분석에 기반하지 않기에 기능과부화(feature creep) 현상의 한 원인으로 지적되고 있다. 본 연구는 사용자에게 새로운 기능을 제공할 경우(혹은 제공된 기능을 제거해야 할 경우), 그 기능으로부터 추론되는 제품-서비스의 멘탈모델을 탐지하는 새로운 기법인 'False belief technique'을 제안하고, 이를 통해 디자이너의 기능 선정(feature selection) 의사결정에 활용될 수 있도록 하고자 한다.

The objective of this study is to examine the effects of consumer beliefs regarding three food certifications on their behavioral intention and the behavioral intention biases to purchase (purchasing intention biases) certified agricultural products as predicted by a subjective probability model. The food certifications used for this study are 'Organic food', 'Traceability system of food products,' and 'Hazard Analysis Critical Control Point (HACCP)'. Tofu (bean curd) was selected as being representative of agricultural food products, for the purposes of this study. In 2016, we surveyed 243 consumers regarding the strength of their belief regarding their prior beliefs relative to each certification, as well as the strength of their intention to purchase certified tofu based on their belief strengths for this study. The study resulted in the following findings: Firstly, consumers hold more than two different prior beliefs for each of the three certifications included in this study. Consumers' prior beliefs regarding these certifications have an impact on their consideration as to whether they plan to buy those certified agricultural products. Secondly, consumers try to persuade themselves to ensure that their particular belief about the product's certification could lead to a purchasing decision regarding that agricultural product.

A sensor fusion scheme for mobile robot environment recognition that incorporates range data and contour data is proposed. Ultrasonic sensor provides coarse spatial description but guarantees open space with no obstacle within sonic cone with relatively high belief. Laser structured light system provides detailed contour description of environment but prone to light noise and is easily affected by surface reflectivity. Overall fusion process is composed of two stages: Noise elimination and belief updates. Dempster Shafer´s evidential reasoning is applied at each stage. Open space estimation from sonar range measurements brings elimination of noisy lines from laser sensor. Comparing actual sonar data to the simulated sonar data enables ...
