Humor is often considered as a positive phenomenon, and thus frequently employed as an impression management technique for individuals. However, humor may create unexpected outcomes in terms of impression management. This study investigates the relationship between humor and impression management of individuals within three South Korean organizations. A qualitative methodology is employed and data collected through participant observation and semi-structured interviews. Findings suggest that humor may be used more frequently by workers in superior positions, and it may be dangerous for individuals in subordinate positions to initiate humor, as negative impressions such as lack of professionalism and work competence may be crafter through humor. In particular, traditional Confucian values and expectations may lead to perceptions that humor is inappropriate and even rude when it is used by individuals in subordinate positions. However, humor may help to craft an independent identity, and help alter user's impressions as desired. This suggests that while perceptions towards humor as an impression management tool may embed significant risks, humor may help individuals to influence their impressions and diverge from a stereotypical expectations and impressions of workers(according to their hierarchical status), which may be interpreted in multiple ways. This implies that organizations should be careful in encouraging workers to use humor as an impression management tactic, as the relational outcomes may be complex, depending on the cultural understanding of hierarchy and relationships between communicators.

The goal of this study is to examine the perceptions of pre-service teachers that directly affect the concepts and ways of the consideration of Earth systems by students studying the water cycle. A concept sketch method was applied to a survey involving 131 pre-service teachers. The survey was designed to analyze the perception of subordinate concepts of Earth systems from the applied components of the water cycle process and to code the applied concepts with components of the water cycle to the subordinate concepts of Earth systems that were the Hydrosphere, the Atmosphere, the Geosphere, and the Biosphere. The survey was designed to examine the perception of the water cycle from the perspective of Earth systems. The recognition by pre-service students was largely confined to components of the atmosphere and the hydrosphere. With regard to the water cycle process, all subjects surveyed recognized precipitation, and most of those expressed recognition of evaporation and condensation. Many of them recognized the surface flow, while they scarcely expressed knowledge of the underground flow.

I examine the relationship between values and security designs of MBS(mortgage-backed securities), using four different types of them. To this end I consider a pass-through and three different kinds of CMOs(collateralized mortgage obligations). It turns out that the pass-through has the lowest value and that, among CMOs, that of a senior-mezzanine-subordinate design has the highest value. This implies that CMOs of a simple and extreme design, like that of a senior-subordinate design, are not likely to be the best CMOs for risk averse buyers. Another critical finding is that the optimal security design of CMOs or MBS does exist in the form of an interior solution. This indicates that MBS issuers could charge higher prices of MBS given their underlying mortgages by tailoring MBS security designs to the needs or utilities of MBS buyers, usually by removing and combining risks of component tranches of MBS. Accordingly a thorough study of realistic utility functions of MBA buyers could enhance the values or prices of MBS to be issued.

Purpose: Due to the explosive growth and widespread use of smartphones, new business opportunities are emerging. Despite the importance of creating customer value in using smartphone applications, past studies on have mainly focused on functions or factors and specifications that influence users to use the device. Methods: This study is intended to identify how customer dissatisfaction from the use of smartphone application services affects customer sentiment and behavior. The research model is tested via a survey of 290 smartphone application users. Results: The result of this empirical study indicates that customer dissatisfaction significantly affects the user's disappointment and regret in using a service, which are subordinate values of customer emotion. The user's anger is positively associated with 'Negative word of mouth' and 'Complaint', which are subordinate values of customer behavior, but not with an intention to switch to another service. 'Regret' and 'Disappointment' are positively associated with 'Negative word of mouth' and 'Switching intention', but not with 'Making direct complaints'. Finally, customer's negative sentiments are a significant intermediary in the relationship between customer dissatisfaction and behavioral response. Conclusion: Finally, the study offers a more systematic understanding on the phasal response process of customer dissatisfaction in relation to the provision of smartphone application services.

The purpose of this study is that we regard the notion of reality that television viewers feel as presence, point out problem of measurement tool that appropriate for TV, clarify the subordinate concept of presence, and develop measurement tool that have reliability and validity. To achieve this, we paid attention to reality of television as a determinant of presence and tried to elicit proper subcategories. That is, we progressed two steps research that distinguished external characteristic and content of the media into sensible reality and cognitive reality, and develop measure item and verified statistical validity. We analyzed the second research result about measurement category of presence selected by first research and then we did Exploratory factor analysis and Confirmatory factor analysis. As a result, the first characteristic that make people experience presence is sensible reality, that is, it is the factor of sensible faithfullness, image faithfullness, and image reality as the form factor of the media. The second characteristic is cognitive reality. That is the factor of social reality, relational reality, and practical reality as the factor of media content. Synthesizing these subordinate factor, we can conceptualize presence experience as a reality of media form and content in HDTV viewing environment.

The purpose of this study was to explore nursing needs during labor pain that had been suffered by women who have given birth. It is essential to identify the nursing needs in order to solve nursing problems and to provide better care for the parturients. The sample consisted of 20 women of primiparas and 17 women of multiparas. They underwent normal labor and delivered a healthy baby at term. The data had been collected through the unstructured interviews conducted 1-2 days after delivery in the admission room from March 1998 to March 1999. On average, the interviews lasted for about 30 minutes. Interviews were taken with the consent of the subjects. The data are categorized according to the similarities of their contents. Seventeen subordinate categories and six superordinate categories have been identified. Six superordinate categories are 1) physical nursing needs 2) nursing needs of medical behavior 3) emotional nursing needs 4) informational and teaching nursing needs 5) nursing needs of pain control 6) nursing needs of respect(personality). Seventeen subordinate categories include: comfortable posture, touch, professional knowledge and techniques, duty execution, support, company and talk, stable surroundings, reassurance, information on delivery, explanation of medical behavior, information on surroundings, instruction on the case of pain, arbitrary adjustment, artificial adjustment, respect, interest and reflection of opinions. The result of this research is the same as that of foreign research and the items of the questionnaire in Korea are the same as the foreign one. Despite the same result, however, this dissertation is significant in that the research identifies the parturients nursing needs and classified the data and thus the basis has been formed to develop the tools to assess the nursing needs of the Korean parturients. The findings can be used as the guide for nursing intervention of parturients.

PURPOSE: This study aimed to investigate the effect of empowerment on job satisfaction for physical therapists in general hospitals. METHODS: A total of 297 physical therapists working in general hospitals throughout the country participated in the study survey using self-administered questionnaires. The questionnaires comprised three major parts, i.e., questions about general characteristics, empowerment, and job satisfaction, which were rated using a 5-point Likert scale. Statistical analysis was performed to analyze the frequency and percentage of participants, and the independent t-test and analysis of variance were performed to determine the difference in job satisfaction according to the general characteristics. Stepwise multiple regression was used to evaluate the factors that affect job satisfaction. RESULTS: The average of total empowerment, including two subordinate concepts, was 3.29 points, that of psychological empowerment was 3.53 points, and that of structural empowerment was 3.05 points. The average job satisfaction of the participants was 3.43 points, and it showed a significant difference in age, overall work experience, current work experience, position, annual salary, and daily work hours. Moreover, job satisfaction increased as the subordinate factors for empowerment, i.e., support, resources, chance, and competence, increased. Other factors that affect job satisfaction were daily work hours, number of colleagues, type of work, annual salary, and therapeutic assistance. CONCLUSION: This study demonstrated that job satisfaction of physical therapists working in general hospitals was related to empowerment, thereby indicating that job satisfaction and work performance can be increased by improving their empowerment.

The purpose of this study is to develop and verify the TPACK measurement tool for middle and high school mathematics teachers in the Korean context. Also, by clarifying the relationship between subordinate factors of Mathematics teachers' TPACK, an attempt was made to provide suggestions on the designs and directions for the in-service and pre-service teacher education and the programs for improving mathematics teachers' TPACK in the future. In order to achieve this goal, TPACK factors of mathematics teachers were extracted by reviewing literature on PCK, MKT, and TPACK. Then, content validity, basic statistical survey, reliability verification, exploratory factor analysis, confirmatory factor analysis, and structural equation model verification were conducted sequentially. At first, preliminary analysis was carried out on 79 mathematics teachers, and 76 items excluding the items with extreme value and reliability were included in the basic statistical analysis. And secondly, an exploratory factor analysis was conducted on 376 mathematics teachers, and this instrument consisted of 7 subordinate factors(CK, PK, TK, PCK, TCK, TPK, TPACK) and 61 items. Also by conducting confirmatory factor analysis and structural equation model test with 254 mathematics teachers, the measurement tool was confirmed the validity and reliability through statistically significant analysis. Then, the importance of integrated knowledge was confirmed by looking at the relationship between the TPACK factors of in-service mathematics teachers. The integrated knowledge(PCK, TCK, TPK) has played a crucial role in the formation of TPACK rather than the knowledge of CK, PK, and TK alone. Finally, the validity of TCK was confirmed through the structural equation modeling of TPACK. TCK not only directly affected TPACK, but also indirectly through TPK. According to these affirmative results, this measurement tool is claimed to be suitable for measuring the factors of Mathematics teachers' TPACK, and also the structural equation model can be regarded as a suitable model for analyzing the structural relationship of mathematics teachers' TPACK.
