The purpose of this study is to propose a method to evaluate task complexity using CIFs(Complexity Influencing Factors). We developed a method that CIFs can be used in the evaluation of task complexity using fuzzy linguistic approach. That is, a fuzzy linguistic multi-criteria method to assess task complexity in a specific task situation was proposed. The CIFs luting was assessed in linguistic terms, which are described by fuzzy numbers with triangular and trapezoidal membership function. A fuzzy weighted average algorithm, based on the extension principle, was employed to aggregate these fuzzy numbers. Finally, the method was validated by experimental approach. In the result, it was validated that TCIM(Tink Complexity Index Method) is an efficient method to evaluate task complexity because the correlation coefficient between task performance time and TCI(Task Complexity Index) was 0.699.

Not only in building design but also in HVAC system design, it is important to ensure an objectivity in schematic design. In the study, the author suggested a method to make a logical decision for quality design factors a(footing the selection of HVAC type in initial design process, and to provide objective design values. Fuzzy theory, one of the theories describing in quantitative way the ambiguous-natured linguistic values, was used to determine the qualitative design factors of linguistic parameter nature. It was found that it has a potential as a method to determine a HVAC type satisfying the required values of qualitative design factors involved in selection of the system type. But this needs further studies to be settled in the selecting of HVAC type.

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.

This study aims at investigating the linguistic and educational factors affecting TOEFL scores, focusing on three OECD countries, Korea, Japan, and Finland. The data comprise document analysis on curriculums, websites, and literature. The findings reveal that the number of Korean test-takers and their TOEFL scores gradually increased year by year. Finnish test-takers consistently gained greatly high scores, and Japanese examinees showed the lowest scores. The languages Korean, Japanese, and Finnish are all far distant from English and receive little support on historical grounds from the Indo-European family tree. In Finland, however, Swedish which belongs to Indo-European languages is still used as an official language with Finnish. Korea and Finland adopt English education from Year 3 in primary school, whereas English is not an official subject in primary school at present in Japan. Finnish students are taught a foreign language in addition to English from primary school. These seem to support the result of the high TOEFL scores of Finnish test-takers. This study concludes that social context which includes linguistic and educational environments are the main factors which affect TOEFL scores.

The national language in the divided Germany has undergone changes that are not simply 'linguistic' in nature but reflect on the diverse social activities that have contributed to the development of the country's political and economic systems. Accordingly, a study of the German language in the process of the division would necessarily involve looking into the socio-political dynamics of the period, in tandem with the study of the linguistic structure per se. This paper deals with the political situation of Germany during the period of 1945 through 1990 and the issues of territorial devision during that period with the view to clarifying the extra-linguistic factors behind the changes of the country's national language. This mode of explaining the heterogeneous linguistic changes that characterize post-war Germany will provide an opportunity to consider the classical issues of the relationship between linguistic changes and social ones in a new light.

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.

The purpose of this study is to examine aspects and causes of the change and disappearance in the Gangneung dialect vocabulary about costume. A typical example of linguistic factors that influence the change of costume vocabulary is competition with the standard language. However, costume as culture has a more powerful effect than linguistic factor. For example, the following factors lead to the disappearance: the disappearance of the referent, the inherent characteristics of the costume, the introduction of the new culture, and the change in values about costume.

The accuracy rate of P2G (Phoneme-to-Grapheme) is one of the important factors determining the quality of unlimited voice recognition (VR) systems. Few studies were, however, conducted to reduce ambiguities of a phoneme string which can be segmented into a variety of different linguistic units (i.e. morphemes, words, eo-jeols), thus be transformed into more than one grapheme string. This paper is a preliminary research for building a large knowledge base of those homonymic & heterographic units(HHUs), which will provide unlimited Korean VR systems with more accurate P2G information. This paper analyzes 2 main factors generating HHUs: (1) boundary determination of the prosodic unit; (2) its segmentation into linguistic units. In this paper, linguistic characteristics determining variable boundaries of a prosodic unit are investigated, and the ambiguity types of HHUs are classified in accordance with their morphological and syntactic structures as well as with the phonological rules governing them.

This study compared the writing of Korean and Korean-Chinese adolescents using K-LIWC (Korean-Linguistic Inquiry Word Count Lee & Yoon, 2005). Three hundred ten (70 : Ulsan, Korea 90 : Yanji, and 150 : Shenyang, China) middle school students wrote a self introductory essay for unknown friends. K-LIWC yielded counts and percentages of word categories using the parts of speech of the Korean language and psychological (emotional, cognitive, sensory/perceptual, social, physical/functional and metaphysical processes) criteria. Results showed that use of pre-noun and present tense correlated with negative mood of the subjects. The writings of Korean-Chinese in Shenyang showed the most negative emotions among the three groups. This was interpreted to be a reflection of better protective factors for Korean-Chinese adolescents in Yanji compared with Shenyang.

Purpose: The aim of this study was to identify the levels of and the related factors to health literacy and health behavior compliance in patients with coronary artery disease. Methods: A cross-sectional survey was conducted with a convenience sample of 121 hospitalized patients with coronary artery disease. The structured questionnaires were used to measure the levels of health literacy and health behavior compliance. Results: The average linguistic health literacy score was $32.23{\pm}21.46$, the functional health literacy score was $6.51{\pm}5.08$, and the health behavior compliance score was $61.66{\pm}15.53$. The levels of education (${\beta}$=.35), income (${\beta}$=.27), and perceived health status (${\beta}$=.21) were found significant, explaining 41.8% of the variance in linguistic health literacy. The levels of education (${\beta}$=.23), income (${\beta}$=.27), age (${\beta}$=-.24), and family support (${\beta}$=.22) were found to be significant, explaining 50.9% of the variance in functional health literacy. The levels of education (${\beta}$=.27), family support (${\beta}$=.20), and linguistic health literacy (${\beta}$=.40) were found to be the significant factors, which explained 45.1% of the variance in health behavior compliance. Linguistic health literacy specifically explained 9.5% of health behavior compliance. Conclusion: Health literacy was associated with health behavior compliance, influencing the factors of health behavior compliance. These findings suggest that the interventions for improving health literacy are necessary to enhance health behavior compliance in patients with coronary artery disease.
