Human reliability analysis (HRA) is a proactive approach to model and evaluate human systematic errors, and has been extensively applied in various complicated systems. Dependence assessment among human errors plays a key role in the HRA, which relies heavily on the knowledge and experience of experts in real-world cases. Moreover, there are ofthen different types of uncertainty when experts use linguistic labels to evaluate the dependencies between human failure events. In this context, this paper aims to develop a new method based on linguistic hesitant fuzzy sets and the technique for human error rate prediction (THERP) technique to manage the dependence in HRA. This method handles the linguistic assessments given by experts according to the linguistic hesitant fuzzy sets, determines the weights of influential factors by an extended best-worst method, and confirms the degree of dependence between successive actions based on the THERP method. Finally, the effectiveness and practicality of the presented linguistic hesitant fuzzy THERP method are demonstrated through an empirical healthcare dependence analysis.

The purpose of the study was to explore the effect of the extensive program using the story telling on young children's linguistic creativity. 20 five-year-olds and 18 four-year-olds from a day care center were selected for this study. After performing pre-test, they were divided into control and experimental group. Children's linguistic creativity was measured using 'Imagining Red' of 'Korean Comprehensive Creativity Test for Young Children' standardized by Chun(2000). 6 books were selected for the extensive program for the promotion of children's linguistic creativity was carried out to experimental group for three weeks. After three weeks, post-test was performed on experimental and control group. The results indicate that the extensive program using the storytelling had an effect on promoting young children's linguistic creativity including the sub-elements such as fluency, flexibility, and originality. As the results of experiencing the extensive program related to storytelling, the linguistic creativity of 5 year olds improved more than that of 4 year aids and that of girls improved more than that of boys. For the developing children's linguistic creativity, various extensive activities need to be programmed.

We propose an algorithmic approach for handling linguistic values defined in the same linguistic variable. Using the proposed approach, we can explicitly capture the differences of individuals' subjectivity with respect to linguistic values defined in the same linguistic variable. The proposed approach can be employed as a useful tool for discovering hidden relationship among linguistic values defined in the same linguistic variable. Consequently, it provides a basis for improving the precision of knowledge acquisition in the development of fuzzy systems including fuzzy expert systems, fuzzy decision tree, fuzzy cognitive map, ok. In this paper, we apply the proposed approach to a collective linguistic assessment among multiple experts.

The research was aimed at finding the dynamic aspects of the linguistic and social interaction with mathematical concept development using a graphing calculator in collaborative learning. This study was broadly divided into two categories: "Knowledge Construction Statement" for understanding how the verbal interaction works when a graphing calculator is used, and "Teacher's Instructional Role" for the research on the reaction of the students and on the teacher's role as a guide in helping students to construct their knowledge. This research used a case study in a collaborative learning environment. An attempt was made to show clearly how the students interacted with one another in a technology environment using a graphing calculator as a tool. A graphing calculator promoted the students' linguistic interaction and changed the characteristics of the linguistic interaction. Although it didn't show the different aspects completely, some changes of the linguistic traits were perceived.aits were perceived.

In this paper, we propose an induced linguistic ordered weighted harmonic mean(ILOWHM) operator. The ILOWHM operator is more general type of aggregation operator, which is based on the LHM and LOWHM operators. Based on the LOWHM and ILOWHM operator, we develop an approach to group decision making with linguistic preference relations. Finally, an application of the approach to group decision making problem with linguistic preference relations is pointed out.

To avoid calamities, the Chinese use different euphemisms in various fields of occupation and region. There are a lot of linguistic taboos concerned with Xieyin that shows the special characteristic of chinese characters. If two characters are homophones and one of them is considered offensive or misfortune, the Chinese prefer to substitute another expression for them in the actual conversations. These substitutes are called euphemisms. As an combined expression of psychological insecurity and language, euphemisms were not only used in the past, but also now they are still in common use. Although some of the chinese euphemisms are not used anymore nowadays, some of them are still used. There are a large number of chinese euphemisms in common use, but some special ones are used in particular fields only. This article focused on the linguistic taboos in some special fields like different regions, occupations and some others related with calamities, and tried to make a distinction from other previous studies. Language reflects culture and euphemism is a mirror of culture. The study of chinese linguistic taboos and euphemisms is expected to be some help to understand the chinese customs and linguistic features.

Substantial amounts of research have been accumulated by the attempt to use linguistic styles as the dependent measure in conducting psychological research. This research was condoned to develope a Korean text analysis program(KLIWC) based on the English text analysis program, LIWC(Linguistic Inquiry and Word Count), and the program reflects the Korean linguistic characteristics and culture that is related with language. We made it possible to analyze agglutinative phrase of many morphemes by linguistic tagging, and basic form dictionary and inflection rule were built. In addition, the face-saving weeds and emotional words were included as the analysis variables. The process of development and characteristics of Korean text analysis have been reviewed, and future direction for the improvement of the program has been discussed.

The purpose of this study was to analyze the characteristic of the linguistic interaction according to leadership type of the leader in the scientific inquiry activity groups and examine how leadership factors affect the linguistic interaction within a group. In this investigation, leaders among 12 elementary school students were chosen by considering results of the leadership diagnosis that tested 3 leadership factors: vision and promotion, assignment responsibility, and decision-making. The members of the groups were organized according to scientific inquiry ability and academic achievement; the groups were assigned to perform scientific inquiry activities. The linguistic interaction was largely divided into the cognitive domain and the affective domain for analysis. According to the results, the frequency of linguistic interaction within a group sorted by leadership type is more influenced by the cognitive domain than the affective domain. The highest frequency of linguistic interaction appeared within the group that had vision and promotion type leader. Assumedly, the vision and confidence of the vision and promotion type leader produced such an outcome. While solving the assignments, linguistic interaction in all three groups had more cognitive domain than affected domain. Linguistic interaction in cognitive domain displayed only low level of linguistic interaction in relation to the experiment itself: high level of linguistic interaction barely occurred. In the case of affected domain, active participation appeared more frequently than maintaining the mood: Interactions related to restricting the group members actions to solve the assignment appeared more frequently than those for maintaining the mood.

In this paper, we present a new fuzzy information retrieval method based on thesaurus. In the proposed method th thesaurus is represented by a fuzzy linguistic matrix, where the elements in fuzzy linguistic matrix represent a qualitative linguistic values between terms. In the fuzzy linguistic matrix, there are three kinds of fuzzy relationships between terms, i.e., similar relation, hierarchical relation, and associative relation. The implicit fuzzy relationships between terms are inferred by the transitive closure of the fuzzy linguistic matrix based on fuzzy theory. And the proposed method has the capability to deal with a qualitative linguistic weights in a query and in indexing of information items to reflect qualitative measure of human based on vague and uncertain decisions rather than a quantitiative measure. Therefore the proposed method is more flexible than the ones presented in papers[1-3]. Moreover our method is more effectual of time than the ones presented in papers[1-3] because we use a fuzzy linguistic matrix and AON (Associate Ordinary Number) values in query evaluation process. As a result, the proposed method allows the users to perform fuzzy queries in a more flexible and more intelligent manner.
