The amount of data a related to a person is so substantial that it appears that a digital version of them can be built thereon. They are usually handled as personal information, and the attempts made to understand personal information have led to bundling and unbundling of various data, yielding numerous fragmented categories of personal information. Therefore, we attempt to construct a generalizable lens for a deeper understanding of person-related data. We develop a theoretical framework that provides a fundamental method to understand these data as an entity of a digitally represented person based on literature review as well as the concepts of inforg and infosphere. The proposed framework suggests person-related data consist of three informational inforg dimensions that can preserve the archetype of a person, form, content, and interaction. Subsequently, the framework is examined and tested through several analyses in two different contexts: social media and online shopping mall. This framework demonstrates the suggested dimensions are interrelated with certain patterns, the prominent dimension can determine the data characteristics, and the dimensional composition of data types can imply the characteristics of the digitally represented person in certain contexts.

The primary goal of this paper was to develop a critical point of view to critical pedagogy when applied to EFL contexts. Critical pedagogy is more concerned about how language can affect personal and social change of teachers and students than it is with how to teach language effectively or in ways that encourage critical thinking on the part of teacher and students. For this goal, this paper introduces the definition, emergence and major constructs of critical pedagogy in a broad way at first. Then, this paper presents how critical pedagogy has an impact on ELT, focusing on how critical pedagogy is applied in ELT contexts and why the application of critical pedagogy in EFL can be criticized, through the review of empirical studies. Reflection of Korean English teaching situation and applicational difficulties of critical pedagogy in Korean ELT are followed.

The purpose of this study was to identify 1) the effect of two contexts (job interview, Informal outing) and clothing cues (type, style, color) on male impresssions 2) the effect of perceiver's age on male impressions created by the clothing cues and contexts. The subjects consisted of 256 male undergraduate students and 256 middle-aged men. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 8 color photographs of drawings of a male figure in clothing which were manipulated in two levels, each of three clothing cues including type, style and color. The experimental design was full factorial design of $(2^4contex^2{\times}clothing type^2{times}clthing color^2$. Each of the 16 sub-samples includes 16 subjects from the two perceiver group. Questionnaires used to measure perceivers responses to the stimuli were 7-point semantic differential scales composed of 37 bipolar adjectives representing personal traits. The data was processed by factor analysis, ANOVA, multiple classification analysis, Duncan's multiple range test. The major findings drawn from this study were as follows: 1. Three factors emerged to account for the dimensional structure of the impressions of the male figure in clothing in two social situations. These factors involved evaluation, activity and uniqueness. 2. The contexts, clothing types and clothing styles had significant effects on evaluation, activity and uniqueness. The clothing styles had a considerable effect on both evaluation and uniqueness while the clothing types affected activity. The clothing color had least effect on the impression and had only moderate effect on evaluation. 3. Perceiver's age influenced impressions formed by the social contexts and clothing cues. Male college students were least affected by contexts and clothing cues, while middle-aged men wert affected most.

The purposee of this study was to identify the effect of perceiver's clothing attitude on male impressions created by the clothing cues and contexts. In addition, the effect of perceiver's evaluations of clothing appropriateness on male impressions. The subjects consisted of 256 male undergraduate students and 256 middle aged men. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 8 color Photographs of drawings of a male figure in clothing which were minipulated in two levels, each of three clothing cues including type, style and color. The experimental design was full factorial design of 2(contexts$\times$clothing types$\times$clothing style$\times$clothing color). Each of the 16 sub-samples includes 16 subjects from the two perceiver group. Questionnaires used to measure perceivers responses to the stimuli were 7-point semantic differential scales composed of 37 bipolar adjectives representing personal traits. Four aspects of clothing attitude(fashion interest, status symbols consiousness, clothing conformity, practicality & comfort)were used to classify subjects into groups of 20 five-point likers type questionnaires adapted from the previous research. Clothing appropriateness were developed 5 point likest scales for evaluation of a stimulus person in each context. The data was processed by factor analysis, ANOVA, multiple classification analysis, Duncan's multiple range test, cluster analysis, MANOVA and pearson's product moment correlations. The major findings drawn from this study were as follows: 1. Perceiver's clothing attitude influenced impression formed by the social contexts and clothing crises. In three groups classified by their clothing attitude, the status symbol-oriented group was most affected by the social contexts and clothing cues. 2. Perceiver's evaluation of clothing appropriateness was related with impressions by a stimulus person. In summary the effect of contexts and clothing cues on impression formation varied according to perceiver's clothing attitude and clothing approopiateness.

Ubiquitous computing is a study area explained in a myriad of contexts and technological terms. So when you try to define it with simple words, it gets even more confusing. Payment. however, refers in nature to an act of money transfer from one entity to another, and it is obvious that a payment method will be valued as long as the transaction can be completed with safety no matter what technology was used. In the end, the key to U-payment is convenience and security in the transfer of financial information. The purpose of this paper is to find a desirable U-payment scheme by looking at the characteristics of seamlessness under the ubiquitous environments, Strong Personal Device, and peer-based if information transactions. We also propose U-SDT Protocol integrating critical technologies such as Radio Frequency Identification (RFID), Bluetooth, Personal Payment Device, Account Managing Application and Transaction ID as a way to make transactions between users seamless and secure better privacy protection.

Purpose - This study aimed to investigate the effects of customer relationship quality and perceived power on complaint behaviors in a context of service failures in a restaurant. Two different types of complaint behaviors were employed: personal complaining that disappointed customers directly approach to a service manager and public complaining that customers ask for related institutions, like consumer protection organization, for help. This study also examined the moderation effects of brand reputation on the relationships between customer perceived power and two types of complaint behaviors. Research design, data, and methodology - The author developed a structural model in which customer relationship quality is proposed to affect customer perceived power, thus influencing personal and public complaint behaviors. The model also includes the moderating role of brand reputation; the effect of customer perceived power on two types of complaint behaviors becomes stronger when brand reputation is high. To analyze the research model, a survey based on a scenario regarding the contexts of service failures in a restaurant was conducted toward 126 female college students. SPSS 22.0 and AMOS 21.0 were utilized to test the hypotheses. Results - The findings are as follows. First, customers who had positive relationships with a restaurant are more likely to perceive that they have strong power to influence the service provider. Second, customer perceived power had a significant and positive effect on both personal and public complaint behaviors. Finally, when the brand reputation for a restaurant is high, dissatisfied customers who think they can exercise influence to the restaurant complain more actively toward the service provider. Conclusions - The findings of this study are against the traditional viewpoint on customer loyalty that loyal customers compared respond more generously to the mistakes of a company, but consistent with the 'love becomes hate' effect proposed by Grégoire, Tripp, and Legoux(2009). In complaining contexts, companies should manage customers with positive and strong relationship more carefully and strategically to prevent the expansion of economic and social risks from customers' complaining behaviors. This is more significant for companies with strong brand reputations.
