The purpose of this study was to describe and understand how diabetics dealt with the result of the various changes of lifestyle. The grounded theory approach of qualitative research methods was used for building a substantive theory about that. The subjects of this study were 10 clients who experienced diabetes from 4 to 30 years. The data was collected from August 1999 to November 1999 through in-depth interviews utilizing home visitation and telephone interview technique then it was and analyzed simultaneously by a constant comparative method in which the new data was continuously coded into categories and properties according to Strauss & Corbin,s methodology. One hundred six concepts were found and they were grouped into 35 categories and then into 14 categories. The results were as follows difficulty, unable to overcome the changes, disposition, disease process, tiredness, supportive environment, perception, handling, concent- ration, mastering, endurance, avoidance, giving up and tailoring. The core phenomenon was 'tiredness' and these categories were synthesized into one core concept, the process of tailoring. The process of tailoring in diabetics consisted of : 1) going through difficulty of disease management 2) experiencing tiredness from the difficulty of disease management 3) perception of disease from tiredness 4) undergoing various self-management 5) controlling the process of tailoring by one's own method. Six hypotheses were derived from the relation of these concepts and four types were from intensity of tiredness, direction of disposition, type of disease process and the level of supportive environment and perception. This study offers better understanding on diabetic experiences and may facilitate more appropriate interventive strategies to provide support, information and knowledge. The nurses should utilize the results to help diabetics enjoy their lives without any trouble and must continuously develop nursing knowledges and skills.

A bandwidth-enhanced ultra-wide band (UWB) CMOS balun-LNA is implemented as a part of a software defined radio (SDR) receiver which supports multi-band and multi-standard. The proposed balun-LNA is composed of a single-to-differential converter, a differential-to-single voltage summer with inductive shunt peaking, a negative feedback network, and a differential output buffer with composite common-drain (CD) and common-source (CS) amplifiers. By feeding the single-ended output of the voltage summer to the input of the LNA through a feedback network, a wideband balun-LNA exploiting negative feedback is implemented. By adopting a source follower-based inductive shunt peaking, the proposed balun-LNA achieves a wider gain bandwidth. Two LNA design examples are presented to demonstrate the usefulness of the proposed approach. The LNA I adopts the CS amplifier with a common gate common source (CGCS) balun load as the S-to-D converter for high gain and low noise figure (NF) and the LNA II uses the differential amplifier with the ac-grounded second input terminal as the S-to-D converter for high second-order input-referred intercept point (IIP2). The 3 dB gain bandwidth of the proposed balun-LNA (LNA I) is above 5 GHz and the NF is below 4 dB from 100 MHz to 5 GHz. An average power gain of 18 dB and an IIP3 of -8 ~ -2 dBm are obtained. In simulation, IIP2 of the LNA II is at least 5 dB higher than that of the LNA I with same power consumption.

Recently, with the attention of future vehicle technology, automobiles that are influenced by user experience(UX) are regarded as living space. However, the concept of term, definition, and constituent factors of driving experience have not been established so far. The purposes of this study are to define driving experience in terms of UX and to extract experience factors. We conducted the 18 drivers interviews and studied literature reviews. The collected interview data was analyzed by bottom-up method based on the grounded theory. And we reconstructed it through the top-down approach, based on the results of the literature review. As the result, the 'driving experience' is a concept that means all the emotions, perceptions, and cognitive outcomes on the basis of personal characteristics that drivers have in anticipation of the driving situation from the start to the destination Respectively. Nine factors that constitute driving experience were extracted by 'internal UI factors', 'environmental factors' and 'user related factors'.

The negative awareness of a multiculturalism rises around the world because of various problems that happen with the multicultural phenomenon. Nevertheless, the reason we uphold multiculturalism is that multicultural phenomenon is an inevitable consequence of capitalism and the decline of multiculturalism might imply danger of bringing about radical nationalism. This study assumes that a distortion of multiculturalism is the result from a myth of romance film which affects the public perception as an integral component of a discourse. Grounded upon monomith, the narrative structure of romance film of which motive comes from courtly love makes people miscomprehend the value of multiculturalism because of the multicultural factor as substitute for romantic obstacle. As the character of romance movie is likely to be formed focusing on superficial images and denotations, this tendency causes the hierarchy and the representative minority drives out the rest of other minorities. The attempt to arouse people's tolerance and understanding of the other is frustrated both by the structure of binary oppositions and the clich$\acute{e}$.

The purpose of this study is to investigate the information-seeking procedure of surveillants against public sector organizations in Korea. The surveillants used accountability mechanisms such as National Assembly Inspection and information disclosure to find out information they wanted. Examples of such group include social activists, professional supervisors, aides of the National Assembly congressman and the press members. Using data collected by in-depth interviews and participative observations, we studied their information seeking behaviors and factors that affect the procedure. Based on the Grounded Theory approach, we first generated 56 concepts, 17 categories and 6 super-categories about the participants' feeling, experiences and perception related to their information seeking. Then we developed a factor model among those generated concepts. The main contributions of this study are a) the results provide a useful guidance for the public information seekers b) we draw the requirements for enhancing public sector organizations' information management systems.

The purpose of this study was to clarity the concept of health insensitivity using Hybrid model, which consists of three phases： theoretical, empirical, and analytic. In the theoretical phase, the definitions of health insensitivity were searched in korean dictionary and examples used in the websites because the concept of health insensitivity has never been studied before. Two dimensions of health insensitivity emerged out from this investigation were cognitive and behavioral. And then a working definition of health insensitivity was established. The sub-concepts and related factors of health insensitivity were identified through the extensive reviews of the literature focusing on two dimensions of cognitive and behavioral. In the empirical phase, in order to obtain description of health insensitivity, face-to-face in-depth interviews were conducted with nine persons who are not related to professional health care. Grounded theory approach was applied to analyze these qualitative data. In the final analytic phase, theoretical results and empirical results were analyzed in the integrated way and a theoretical framework of health insensitivity was established. A refined definition of health insensitivity was that decreased health risk perception in cognitive dimension and conduction of the unhealthy behaviors in behavioral dimension. Sub-concepts of decreased health risk perception were optimistic bias and decreased general fear. Sub-concepts of unhealthy behavior were doing health threatening behavior and not doing desirable health behavior. The contact of health information was a causal condition of health insensitivity. Optimistic disposition, health locus of control, and avoidance coping style were intervening conditions of health insensitivity. Three types of health insensitivity were identified： unconcern or ignorance type, optimistic bias type, and cognitive dissonance type. Finally, The implications of these findings for further research and nursing practice are discussed.

In order to help students through their initial clinical experience, faculty must understand more fully the moaning of this experience for nursing students. This study was performed to understand and to explain what is the essential structure of nursing students' initial clinical experience. A grounded theory approach was conducted to explore the actual experience of nursing students' first clinical experience. Each of the nursing students' descriptions about their initial clinical experience was analyzed using Strauss & Corbin's method. The results of the study were as follows : From the 172 written descriptions and 7 in-depth individual interviews, 128 concepts were extracted. After identifying the concepts' formulated meaning, they were organized into 29 subcategories and the following 12 categories . burden, encountering difficulties, self-discovery, grasping actuality, acquirement of nurse's nature, special character of experience, special character of relationship, external effect, problem oriented coping, emotional oriented coping, affection for nursing, skeptical view of nursing. Five hypotheses were derived from the analysis. 1) Burden is an obstacle to grasp nursing actuality. 2) Special character of experience and external effect have an effect on grasping nursing actuality, 3) Encouragement, a part of external effects, will increase nursing student's affection for nursing. 4) Affection for nursing through first clinical experience facilitates positive nursing view and scholarly zest. 5) Disappointment with the difference be tween theory and reality will cause the student to take a skeptical view of nursing. It is hoped that the knowledge gained from this qualitative study will enable faculty to enter more fully Into the world of nursing students as they embark on their initial clinical experience.
