  • In this study, we measured the wind data as new and renewable energy resources and carried out the evaluation of uncertainty about these data with the authentic standards. These data collected at the 20 locations in korea. We carried out the processing and evaluation about these data with standards as ISO, GUM, and IEC. Whereby these data become standards data and the credibility are gained. These data include some information as direction, humidity, pressure, temperature, and energy density. The annual average of wind speed(in Hamo) was measured as 9.5m/s, then the uncertainty was evaluated as ${\pm}0.88m/s$. We judge the credibility of data by expression of reliability quantitatively. In additional, the standards data is able to approach anywhere and it will be used to support of related research and industry.

  • The advent of microarray technologies gives an opportunity to moni tor the expression of ten thousands of genes, simultaneously. Such microarray data can be deteriorated by experimental errors and image artifacts, which generate non-negligible outliers that are estimated by 15% of typical microarray data. Thus, it is an important issue to detect and correct the se faulty probes prior to high-level data analysis such as classification or clustering. In this paper, we propose a systematic procedure for the detection of faulty probes and its proper correction in Genechip array based on multivariate statistical approaches. Principal component analysis (PCA), one of the most widely used multivariate statistical approaches, has been applied to construct a statistical correlation model with 20 pairs of probes for each gene. And, the faulty probes are identified by inspecting the squared prediction error (SPE) of each probe from the PCA model. Then, the outlying probes are reconstructed by the iterative optimization approach minimizing SPE. We used the public data presented from the gene chip project of human fibroblast cell. Through the application study, the proposed approach showed good performance for probe correction without removing faulty probes, which may be desirable in the viewpoint of the maximum use of data information.

  • The purpose of this study was to investigate the differences in female college students' sociocultural attitude toward appearance and pursuit of clothing benefits according to their narcissism. Data collection was conducted through survey for female college students, and a total 221 questionnaires were used for data analyses. For analysis of data, frequency analysis, factor analysis, reliability analysis, and one-way ANOVA were applied. The results were summarized as follows. First, the factor analysis on narcissism resulted in two dimensional structures: self-initiated and other-dependent narcissism. The respondents were categorized into four narcissism groups, such as compositive, self-initiated, other-dependent, and withdrawn narcissism groups. Second, the factor analysis on sociocultural attitude toward appearance resulted in two dimensional structures: internalization and awareness. Five dimensions of pursuit of clothing benefits were identified: individuality, self-expression, fashion, comfort, and social recognition pursuit. Third, there were significant differences among the categorized narcissism groups in sociocultural attitude toward appearance and pursuit of clothing benefits. The results confirm that narcissism has an impact on sociocultural attitude toward appearance and pursuit of clothing benefits. It is expected that this study provides insight for apparel makers or retailers to develop their marketing strategies.

  • Purpose: This study was done to analyze the effect of supervisor-focused impression management behavior of the airline cabin crew on perceived customer empathy. It focused on verifying dual meanings of the crew's emotional expression divided into surface acting and deep acting. Research design, data and methodology: The survey was conducted on cabin crews of two major Korean airlines. The reliability and validity of each variable used in the questionnaire were verified. Then, each hypothesis was analyzed through multiple regression analysis. Results: Firstly, the crew's supervisor-focused impression management behavior had a significant effect only on surface acting of the crew's emotional labor behavior. Among the crew's supervisor-focused IM behaviors, verbal IM behavior had a greater influence on surface acting than non-verbal IM behavior. Secondly, there was no relationship between the crew's supervisor-focused IM behavior and the crew's deep acting. Thirdly, the crew's emotional labor behavior (surface acting & deep acting) had a significant effect on perceived customer empathy. Fourth, the crew's deep acting had a greater influence on perceived customer empathy than surface acting. Conclusions: Cabin crews receive double evaluation from their immediate supervisors and customers. As a result, it was confirmed that the crew's supervisor-focused IM behavior, the crew's emotional labor behavior, and perceived customer empathy were connected process.

  • This study is conducted to analyse the process and the pattern of motivation for musical expression in clinical music therapy for the adults in the mental health center. The participant were 8 adults purposive sampling who had more than one year music therapy experience in the mental health center and their age ranged from 27 to 53. A major category derived and analysed from the grounded theory method by Strauss and Corbin. The qualitative analysis indicated that motivation for musical expression in music therapy, which was the central phenomenon in this study, was determined by the music therapist and songs used in the sessions. The central phenomenon was caused by the therapist's friendly attitude, high musical capacity, the familarity of the selected songs and the significancy of the lyrics of selected songs. The levels of reliability about the therapist's personality and musical ability as a professional music therapist and the positive arousal of the songs used in sessions affected as the contextual condition. Spontaneous musical expression in music therapy brought the escape from reality, release of stress and sharing by the intervening condition 'empathy' and this resulted in mood regulation, the instillation of hope and group cohesion. It has been found that there were three types of motivation in music therapy: intrinsic motivation, relationship dependent extrinsic motivation and evasive motivation.

  • The purpose of this study is to classify students' attitudes towards uniform modification and analyze their subjective experience regarding appearance, and body satisfaction. Questionnaires were administered to 369 middle and high school girls living in Deagu Metropolitan City. Frequency, factor analysis, reliability analysis, correlation analysis, ${\chi}^2$-test, and t-test are all used for data analysis. Our findings are as follows. Two hundred thirty students (62.3%) agreed to modify their school uniforms to express their personalities and follow fashion trends. Motives for uniform modification had to do with social life, physical attractiveness, and practicality. Attitudes toward appearance are found to be shaped by appearance internalization, active management of appearance, appearance needs, social recognition, and conformity. The motives for uniform modification reveal a significant correlation with attitudes toward appearance. Uniform modification satisfaction differed depending on sub-variables of attitude toward appearance(active management of appearance, personalized appearance needs, social recognition, and body satisfaction, such as satisfaction with height and BMI). There was a significant difference in expression of intention for future plastic surgery depending on body image.

  • Aure's tonality was considered as the sound metrics for the expression of the tonality of gear whine sound in a previous research. It was failed to use the Aure's tonality as a sound metric for the tonal impression. Thus Aures's tonality, was developed for tonal impression in previous research. However, this metric did not express well the tonality of gear whine sound since the whine sound is a non-stationary signal with frequency modulation and amplitude modulation. In this study, the new method for the tonality evaluation for a non-stationary signal is presented. It is developed based on the prominence ratio, tonality impression function, and lower threshold level. It improves the accuracy and reliability of the sound quality index being used for the sound quality evaluation of the axle-gear whine sound.

  • Web 2.0 which is characterized by openness, sharing with others and users' active participation has a strong impact on Individual and business environments. New technology such as open-API, RSS, collective intelligence gives various benefits to the website user. Recently, the Web 2.0 paradigm has also affected the public service. Many public service organizations are also adopting Web 2.0 applications to improve their ability for serving users more effectively. However, there is a contradiction between value of public service and that of web 2.0. Web 2.0 which pursues openness and freedom of expression can impair the accuracy and reliability of public information in the public sites. We conducted a case study on EBS which reflects the Web 2.0 strategy for websites renewal. To cope with environmental changes, EBS began reorganization of the web site and applied Web 2.0 strategy for leveraging an easy to use and user satisfaction. This research shows that how to Implement the Web 2.0 strategy and what is the limitation of it. The findings of this study suggest practical implications for Web 2.0 strategy in public web sites, especially for educational fields.
