This study identifies consumers' perceived benefits and costs when using Samsung Health (a healthcare app) based on consumer reviews from Google Play Store's app and social media discourse. We examine the differences in the benefits and the costs of Samsung Health using these two sources of data. We conducted text frequency analysis, clustering analysis, and semantic network analysis using R programming. The major findings are as follows. First, consumers experience benefits and costs on several functions of the app, such as step counting, device interlocking, information acquisition, and competition with global consumers. Second, the results of semantic network analysis showed that there were eight benefit factors and three cost factors. We also found that the three costs correspond to the benefits, indicating that some consumers gained benefits from certain functions while others gained costs from the same functions. Third, the comparison between consumer app review and social media discourse showed that the former is appropriate to assess the performance of app functions, while the latter is appropriate to examine how the app is used in daily life and how consumers feel about it. The current study suggests managerial implications to healthcare app service providers regarding what they should strengthen and improve to enhance consumers' satisfaction. It also suggests some implications from the two media, which can be mutually complementary, for researchers who study consumer opinions.

The artificial intelligence speaker market is in a new age of mounting displays. This study aimed to analyze the difference of experience using artificial intelligent speakers in terms of usage context, according to the presence or absence of displays. This was achieved by using semantic network analysis to determine how the online review texts of Amazon Echo Show and Echo Plus consisted of different UX issues with structural differences. Based on the physical context and the social context of the user experience, the ego network was constructed to draw out major issues. Results of the analysis show that users' expectation gap is generated according to the display presence, which can lead to negative experiences. Also, it was confirmed that the Multimodal interface is more utilized in the kitchen than in the bedroom, and can contribute to the activation of communication among family members. Based on these findings, we propose a user experience strategy to be considered in display type speakers to be launched in Korea in the future.

The purpose of this study was to investigate the characteristics of error types in naming task for 8 questionable demeatia groups, 9 definite dementia groups, and 10 normal groups. The items of naming error analysis were classified into visual perception errors, semantic association errors, semantic non-correlation errors, phoneme errors, Don't Know, and No Response. For the analysis, descriptive statistics analysis, analysis of variance, and multivariate analysis of variance were conducted using SPSS 21.0. As a result, there was a significant difference in the error rate between groups according to the error type. The errors that showed significant differences between the normal group and the other two groups were visual perception errors and semantic non-related errors. The error of non-response was different from the dementia confirmation group, but there was no significant difference from the dementia suspicion group. These results showed that Alzheimer's patients had a defect in confrontation naming ability. Also, it was found that it is appropriate to provid other clues when the defects caused by the degeneration of a specific step during the information processing process become severe.

Discovering the suppliers capable of manufacturing the parts that satisfy buyer requirements via current online market places remains difficult due to semantic differences between what the suppliers can produce and what the buyer wants to acquire. One of the promising approaches to overcome the semantic difference is to adopt an ontology to describe the suppliers' manufacturing capabilities and the buyer requirements that range widely from manufacturing costs to eco-friendly design. Such an ontology dedicated to supplier discovery has yet to be developed. MSDL(Manufacturing Service Description Language) provides the basis for defining terms and their relationships in the ontology. Thus, the objective of this paper is to extend MSDL into a new ontology suitable for supplier discovery in mold manufacturing industry. In addition, a new ontology development method for supplier discovery will be proposed. Finally prototype demonstrations are provided to show a feasibility of the proposed ontology in mold manufacturing domains.

The purpose of this study was to find out the psychological distance through semantic app-roach perceived by adolescent child in the subtypes of 'Extrem Family' dysfunctional families by classification of Olson and his associates ' Circrumplex Model. The subjects of this research were 1072 abolescents living in Seoul. Korea The survey methods were questionnaires including FACES II and The Psychological Distance Scale. Data were analyzed by means of the statistics of frequency percentage arithematic mean standard devia-tion crosstabs and one way-anova. The major findings are as follows: 1) The levels of family cohesion family adaptibility and the psychologival distances with father mother and siblings perceived by adolescent were high. 2) The most of subject's families belonged to 'Balanced Family' in the types of family system ' Extreme Family' type showed the lowest frequency and the main subtypes of it that had the highest frequency were 'Enmeshed Chaotic Family' ' Disengaged Rigid Family' 3) While adolescents of 'Enmeshed Chaotic Family' perceived most closely with other family members. those of 'Disengated Rigid Family' most distantly totally and in evaluation potency and activity three subfactors in psychological distance. 4) There were differences of unit points in subfactors of psychological distances with other family members perceived by adolescents according to the types of family system. While the points of 'Enmeshed Chaotic Family' were the highest those of 'Disengaged Rigid Family' were the lowest. 5) While 'Enmeshed Chaotic Family' were located most closely 'Disengaged Rigid Family' were located most distantly in the mutual distances and direct distances among family concepts on semantic space.

In order to investigate the relationship between subjective sensation for fabric sound and touch and the objective measurements, eight different apparel fabrics were selected as specimens. Sound parameters of fabrics including level pressure of total sound (LPT), level range (ΔL), and frequency differences (Δf) and mechanical properties by Kawabata Evaluation System (KES) were obtained. For subjective evaluation, seven aspects of the sound (softness, loudness, pleasantness, sharpness, clearness, roughness, and highness) and eight of the tough (hardness, smoothness, fineness, coolness, pliability, crispness, heaviness, and thickness) were rated using semantic differential scale. Polyester ultrasuede was evaluated to sound softer and more pleasant while polyester taffeta to sound louder and rougher than any other fabrics. Wool fabric such as worsted and woolen showed similar sensation for sound but differed in some touch sensation in that woolen was coarseast, heaviest, and thickest in touch. In the prediction model for sound sensation, LPT affected positively subjective roughness and highness as well as loudness, while ΔL was found as a parameter related positively with softness and pleasantness. Touch sensation was explained by some of mechanical properties such as surface, compressional, shear, and bending properties implying that a touch sensation could be expressed by a variety of properties.

We examine attributive possessive constructions in Korean in examples like wuli manwula 'my wife' and wuli nala 'my country', where an apparently plural pronoun wuli 'our' is used to convey the singular meaning of 'my.' An example like wuli manwula has been a frequent topic of joke, because it clearly contains the literal sense of 'shared wife.' This type of use and the frequent use of wuli in an exclusive my context led many to claim that these are products of Korean culture which emphasizes groups and group solidarity over individuality, the example wuli manwula being the extreme case. Drawing on the work of Taylor (1989; 1996), Croft (2001; 2003), Haspelmath (1997; 2003), and 윤재학 (2003), we compare the meanings of Korean and English possessive constructions and seek a more linguistically based account for the data. In particular, it is shown that (i) wuli in question is not really the plural form of nay 'my', (ii) the possessive constructions in Korean are more conservative and limited in possible relations than the English counterparts are, and that (iii) these two facts interact to produce the afore-mentioned uses.
