  • Transcendental numbers are important in the history of mathematics because their study provided that circle squaring, one of the geometric problems of antiquity that had baffled mathematicians for more than 2000 years was insoluble. Liouville established in 1844 that transcendental numbers exist. In 1874, Cantor published his first proof of the existence of transcendentals in article [10]. Louville's theorem basically can be used to prove the existence of Transcendental number as well as produce a class of transcendental numbers. The number e was proved to be transcendental by Hermite in 1873, and $\pi$ by Lindemann in 1882. In 1934, Gelfond published a complete solution to the entire seventh problem of Hilbert. Within six weeks, Schneider found another independent solution. In 1966, A. Baker established the generalization of the Gelfond-Schneider theorem. He proved that any non-vanishing linear combination of logarithms of algebraic numbers with algebraic coefficients is transcendental. This study aims to examine the concept and development of transcendental numbers and to present students with its open problems promoting a research on it any further.

  • purpose : The purpose of this study was examine the effect of self-transcendence and loneliness on quality of life of the elderly. Method : This was a descriptive survey study. The subjects was 171 elderly persons. Descriptive statistics, Pearson's correlation, and stepwise multiple regression were used in analysis of data. Results : Average score were 2.7 for self-transcendence, 2.0 for loneliness, and 3.0 for quality of life. Statistically significant positive correlations were observed between quality of life and self-transcendence. however, from the statistical point view, significantly negative correlation was observed between quality of life and loneliness. self-transcendence, economic status, general health status, loneliness and spouse were significant predictors of quality of life. Conclusion : This study will provide basic information for use in development of a program to encourage a quality of life for elderly persons.

  • NGE (Nested Generalized Exemplars) proposed by Salzberg improved the storage requirement and classification rate of the Memory Based Reasoning. It constructs hyperrectangles during training and performs classification tasks. It worked not bad in many area, however, the major drawback of NGE is constructing hyperrectangles because its hyperrectangle is extended so as to cover the error data and the way of maintaining the feature weight vector. We proposed the OH (Optimizing Hyperrectangle) algorithm which use the feature weight vectors and the ED(Exemplar Densimeter) to optimize resulting Hyperrectangles. The proposed algorithm, as well as the EACH, required only approximately 40% of memory space that is needed in k-NN classifier, and showed a superior classification performance to the EACH. Also, by reducing the number of stored patterns, it showed excellent results in terms of classification when we compare it to the k-NN and the EACH.

A Study on the Structural Impact of Job Stress on the Organizational Commitment and Customer Oriented Boundary Spanning Behavior of Hospital Employees (병원종사자의 직무스트레스가 조직몰입과 고객지향영역초월행동에 미치는 구조적 영향관계 분석)

  • This study examines the impact of job stress on customer-oriented boundary-spanning behavior with the mediating effects of organizational commitment. The survey data was collected from 147 employees working at a hospital and analyzed statistically by using SPSS 18.0 and AMOS 18.0. The result of this study are as follows. Hypothesis 1, Job stress has a negative influence on organizational commitment. Hypothesis 2, Organizational commitment has a positive influence on customer-oriented boundary-spanning behavior. Hypothesis 3, Job stress has a negatively significant impact on customer-oriented boundary-spanning behavior. Accordingly, Organizational commitment has the role of partially mediating the effect between job stress and customer-oriented boundary-spanning behavior. This means that employees working at the point of meeting customers must reduce their job stress in order to improve the service quality of a hospital and creating solutions to reduce job stress of hospital employees can increase customer-oriented boundary-spanning behavior.

  • Recently, both scholars and marketers have asserted the importance of boundary spanning behaviors, such as external representation, being vocal advocates to outsiders of the organization's image, goods, and services, internal influence, taking individual initiative in communications to the firm and co-workers to improve service delivery by the organization, co-workers, and oneself, and service delivery, serving customers in a conscientious, responsive, flexible, and courteous manner. However, there is lack of study dealing with bourdary spanning behaviors bewteen organizational dyads, in which boundary spanning behaviors are expected to have important roles. The objectives of this paper is to investigate these important concerns with prior research by developing a theoretical model predicting how distinct buyer's boundary spanning behaviors occur. To be concrete, this paper develops a seller characteristics-based model of the attitudinal antecedents of three conceptually distinct forms of boundary spanning behaviors, and tests the hypothesized differential effects of seller characteristics on the three forms of boundary spanning behaviors, and investigates the extent to which these relationships are mediated by relationship satisfaction and organizational commitment. For the purpose of empirical testing, 420 respondents of leading automobile dealers, dining franchisees, industrial material retailers in Korea were surveyed and the analysis utilizing structural equation model indicated that communication quality, fairness, and marketing program dynamism had positive effects on buyer's boundary spanning behaviors via relationship satisfaction and organizational commitment. In addition, boundary spanning behaviors occurred more in contractural and corporate distribution channel than in conventional distribution channel.

  • The purpose of this study was to identify predictive factors of successful aging and to determine mediating effect of transcendence between successful aging and influencing factors of community-dwelling elders in Korea. 162 elders were participated in this study who visited seniors welfare center and senior citizen center. Data were analyzed by PASW 18.0 for t-test, Pearson's correlation coefficients and hierarchical regression analysis. Transcendence, parent-child relationship, depression, spirituality and perceived economic status were statistically significant influencing factors, explained 77% of successful aging in community-dwelling elderly. The mediating role of transcendence was identified about parent-child relationship, depression, spirituality and perceived economic condition. The study findings demonstrated that transcendence was significant variable affecting successful aging. The variables affecting successful aging such as transcendence, parent-child relationship, depression, spirituality, perceived economic status can be utilized for nursing strategies to successful aging in community-dwelling elders.
