This study is to understand and to describe the power that a nurse experiences on nursing practice and then. to present a basic data for nurse's power-development, power improving and empowering. Ethnography was used to understand and to describe experience on exercising various powers occurred on nursing practice. and to analyze and to understand the meaning of a nurse's power. The objects was nurses. Ten nurses who have more than three year's experience were selected as objects from Cuniversity's hospital in Seoul from May of 1996 to August of 1997 through in-depth interview. participant observation, and phone interview. Instruments werw a portable recorder and field notes. I described a case appeared in a data using Agar's 'Pencil and scissors' method right after collecting materials. Then, Idescribed a theme discovered commonly. Followings are the results of the study. 1. There were three categories of relationships with main objects when nurses exercised their power on their practices: a therapeutic caring relationship with patients, a relationship of companion, vertical cooperation, and a constituent person with a doctor, and a relationship of cooperation, and a constituent person with administrative workers and medical technicians. 2. There were many types of nurse's power, tactics and various patient's responses about them. 1) Types of nurse's power to patients were giving information, controling environment, helping for cure, emotional support, and performing discretion. 2) Nurse's tatics for performing power were positive tactics neutral tactics, and negative tactics. 3) Patient's responses were appeared as compliance and noncompliance. Compliance were agreeing. taking nurse's advice, trusting, understanding, being admitted, exposuring himself, and appreciating. 3. There were types of nurse's power and performing tactics. 1) Types of power to a doctor were advice, informing, demanding and mediation. 2) Performings of tactics to a doctor were positive tactics, neutral tactics, and negative tactics. 3) Doctor's responses were appeared as accepting and unaccepting. Acceptings were taking in and appreciating, and unacceptings were denying nurse's advice and authoritative. 4. There were types of nurse's power and tactics about administrative workers and medical technicians and responses about them. 1) Types of power about administrative workers and medical technicians were suggestions and demands. 2) Power performings tactics were positive tactics.neutral tactics, and negative tactics. 3) Responses of administrative workers and medical technicians about nurse's power performing were appeared appeared as accepting and unacce pting. Acceptings were taking in, and unacceptings were denying. Therefore, it can be said that types of nurse's power and performing tactics on nursing practice and nurse's power based on responses of a patient, a doctor, an administrative worker, and a medical technicians are power or influence for agreeing, taking advice, trusting, understanding, exposuring himself, appreciating, and taking in to objects. The results of this study helped to understand nurse's power. I expect that this study will improve nure's power by using expert power, referent power, and legitimate power effectively among powers acmpanied with the origin and that nurses make ef-ort to improve professional knowledge and human nature so that they use this study as a chance to develope expert nursing practice.

Objectives: To investigate in depth the use of complementary and alternative medicines (CAMs) by cancer patients at the end-of-life (EOL) and how they communicate with physicians about them. Design and location: In 17 hospitals in Korea between January and December 2004 we identified 4,042 families of cancer patients. Results: The prevalence of CAM use among cancer patients at the EOL was 37.0%, and 93.1% had used pharmacologic types of agents. The most frequent motive for CAM use was the recommendation of friends or a close relative (53.4%) or a physician (1.6%). Only 42.5% discussed CAM use with their physicians. Satisfaction with CAMS was recalled for 37.1%. The most common reason given for that satisfaction was improvement of emotional or physical well-being, while ineffectiveness was the most common reason given for dissatisfaction. The average cost of CAM during the last month of life was $US 900. CAM use was associated with longer disease periods, primary cancers other than liver, biliary, and pancreatic, and need of support from physicians or religion. Conclusions: CAM use among cancer patients at the EOL was common, not discussed with physicians, and associated with expectation of cure. Expectations were generally unmet while the treatments were a financial burden. Further studies evaluating the effects of CAM at the EOL and factors that enhance communication with the physician are needed.

Purpose: The purpose of this study was to analyze the reason to select complementary and alternative therapy for terminally ill cancer patients. Methods: The data were collected from 21 terminal cancer patients and families through the in-depth interview. Data analysis were performed by the Colaizzi's phenomenological method (1976). Results: The reason to select complementary and alternative therapy for terminal cancer patients and families was then categorized with 4 elements; Awareness of limitations in contemporary medical treatments, Belief in effectiveness of the CAM, Satisfaction with emotional needs of family members, and Disbelief due to negative attitudes of physicians. The result indicated the following 9 themes expectation for a complete cure, uncertainty in hospital treatments, complementary method for management of side effect of chemotherapy, alleviation of symptoms and life-sustaining, fear for side effects of cancer treatments, belief in earned information, referrals by other, responsibility of family, and dissatisfaction with negatine attitudes of physicians. Conclusion: Physicians should provide a sufficient explanation and try to effectively communicate with clients about hospice and palliative service and the CAM. We strongly realized that concerns about patients' best care and satisfactions with family's needs should be understood.

This study has been performed to analyze the experience of parents who had led a parents-group of children with cancer. For this study, fifteen participants were selected for an in-depth interview and the personal experiences of each participant had been interviewed in person until data were saturated. This study employed the grounded theory approach of Strauss and Corbin(1998). With the qualitative constant comparative analysis, ninty four concepts, twenty six subcategories, and seventeen categories were generated. In the axial coding, a paradigm model was proposed as follows: The central phenomenon of the leaders' experiences was that they had been 'Pushed Back' to lead the groups. The causal conditions were 'A Sense of Solidarity', 'Regaining Self-possession', and 'Feeling a Necessity of Parents Group'. The contextual conditions were 'Want to Help', 'A Sense of Mission', and 'Discontent with the Cure Environment'. The intervening conditions were 'Self-reflection of Leadership', 'Reaction of Their Own Family', 'Hope to Have an Expanded Group'. The action/interaction strategies were 'Assuming All Field Work', 'Accumulation of Experiences', 'Recognition of a Role Scope'. The consequences were 'Being Comforted', 'Positive Self-awareness', 'a Sense of Worthiness', and 'Desire to Quit'. In the selective coding, the core category was 'Pushed to Lead a Group'. Based on the core category, four types and five stages in the leaders' experiences were identified. The types include 'a Devoted Family Type', 'a Volunteer Type', 'a Role Model Type', and 'a Activist Type': the stages consist of 'Stage of Maintain Identity as a parent of a child with cancer', 'Stage of Questioning', 'Stage of Active Participation', 'Stage of Experience Accumulation', and 'Stage of Progressive Change'. The result of this study presents some implications and suggestions for social work services and theories with respect to the self-help group of pediatric cancer by attempting to understand more about the experiences of leaders' in such groups.

Objective : The purpose of this study was to evaluate the effects of several light curing methods and several adhesives on the microleakage of composite resin restorations in primary teeth. Materials and methods : In 150 extracted human primary anterior teeth, O-shaped cavities were prepared in the labial surface ; the cavity diameter and depth were 1.6mm. The cavities were filled with light-activated composite resin, Compoglass. Four kinds of adhesives were used. Each filling materials were polymerized with three light cure methods. The restorations were polished using Sof-Lex discs(3M Co., USA). The samples were thermocycled 1,000 times between $5^{\circ}C$ and $55^{\circ}C$ with a 1-minute dwell time. Then, they were immersed in a 2% methylene blue solution(pH 7) for 12hours. Subsequently they were sectioned labio-lingually through the center of the restoration with a diamond saw at low speed with a water coolant, and evaluated by stereomicroscopy. Microleakage analyses were done, using scores from 0 to 4. Results : Results showed the least microleakage in Compoglass group(P<0.05). There were less microleakage in SBMP group among the adhesive groups, but no significant difference was observed(P>0.05). And there were no significant differences among the groups depending on curing methods(P>0.05).

Purpose : The purpose of this study was to describe a total pain model in patients with terminal cancer and to identify factors relating to total pain using the Twycross Pain Management Model, which included physical, psycho-social and spiritual pain. Method : The study was a retrospective descriptive study. The first stage included 87 patients who received hospice service at Y hospital in 1997. The second stage included five model patients who suffer severe pain as selected by the four hospice nurses. Data collection was from 1) chart analysis and 2) in-depth interviews with the hospice nurses about their selected patients. Data analysis was performed using SPSS-WIN and content analysis. Result : 1) The main problems of 3 patient with terminal cancer were pain(77%), constipation (25.3%), family coping(35.6%), psycho-spiritual distress(17.2%)and other symptoms. 2. The Twycross model was a useful model. However, new items were added; loneliness, depression, and no improvement in condition as depression factors. In anger, new items were anger due to family neglect, at God and in relationships. The case studies identified the followsing; 1) Patient suffer from physical pain as well as multiple other symptoms when cancer is advanced. 2) Body concept, role change, threat to self concept, fear of pain, fear of death, anxiety, family conflict, financial burden, spiritual distress, hope for a cure, are all affected. Conclusion : 1) It is believed that the Twycross model is useful but further tests and revisions are necessary for deciding priorities in the care plan. 2) Pain management must improve culturally appropriate and family support, psychological, spiritual care are imperative for patient with terminal cancer. 3) Further study is recommended to test correlations of depression, anxiety, spiritual distress and family coping using valid instruments. A qualitative study on the spiritual journey of the patient with terminal cancer is also recommended.

The aim of this study was to develop a method for measuring the slumping resistance of resin composites and to relate it to the rheological characteristics. Five commercial hybrid composites (Z100. Z250. DenFil, Tetric Ceram. ClearFil) and a nanofill composite (Z350) were used to make disc-shaped specimens of 2 mm thickness. An aluminum mold with square shaped cutting surface was pressed onto the composite discs to make standardized imprints. The imprints were light-cured either immediately (non-slumped) or after waiting for 3 minutes at $25^{\circ}C$ (slumped). White stone replicas were made and then scanned for topography using a laser 3-D profilometer. Slumping resistance index (SRI) was defined as the ratio of the groove depth of the slumped specimen to that of the non-slumped specimen. The pre-cure viscoelasticity of each composite was evaluated by an oscillatory shear test and normal stress was measured by a squeeze test using a rheometer. Flow test was also performed using a flow tester. Correlation analysis was performed to investigate the relationship between the viscoelastic properties and the SRI. SRI varied between the six materials (Z100 < DenFil < Z250 < ClearFil < Tetric Ceram < Z350). The SRI was strongly correlated with the viscous (loss) shear modulus G' but not with the loss tangent. Also. slumping resistance was more closely related to the resistance to shear flow than to the normal stress. Slumping tendency could be quantified using the imprint method and SRI. The index may be applicable to evaluate the clinical handling characteristics of composites.

The purpose of study was to compare the plasma arc light with the halogen light in compostie resin curing. Three composite resin materials(Z-100, 3M, USA; Tetric Ceram, Vivadent, Liechtenstein; SureFil, Dentsply, USA) were filled in the teflon molds (4mm in diameter and 2, 3, 4, 5mm in thickness) and cured with either the conventional low-intensity light curing unit with a halogen lamp (Optilux 360, Demetron, U.S.A.) for duration of 40 seconds or with the high-intensity light curing unit with a plasma arc lamp (Flipo, Lokki, France) for duration of 3, 6, and 9 seconds. The intensity of halogen light was about $370mW/cm^2$ and that of plasma light was about $1,900mW/cm^2$. After one week, the surface hardnesses of both the top and the bottom of the resin samples were measured with a microhardness tester(MXT70, Matsuzawa, Japan). There were significant differences in the hardness between the top and the bottom of the resin samples except the 2mm thickness samples cured by halogen light for 40s or by plasma light for 9s. There was no significant difference between the hardness values of the top surfaces of the thickness groups. The hardness values of the bottom surfaces decreased as the curing time decreased and as the thickness of resin samples increased, and the three kinds of resin composites showed similar patterns. The results suggest that the halogen light for 40 seconds might be able to cure greater depth of resin composites than the plasma light for 3, 6, or 9 seconds.

The purpose of this study was to explore the implications of the integrated support through the 'health - medical - welfare' network and the specific context of the operation through the experiences of the users who participated in the 301 network project of Seoul northern municipal hospital. To do this, In-depth interviews were carried out with 10 research participants. The data was analyzed by general qualitative research methods. As a result of analysis, users lost their willingness because of living in a vicious cycle of poverty and illness before participating in 301 network services, but through the participation of the service, they were able to receive the integrated support of 'cure-care-life stability'. These experiences ultimately led to the regeneration of the will of their lives. At the basis of this experience were operating strategies and conditions such as the formation of a diverse professional team, the establishment of a linkage system within and outside the hospital, the establishment of a treatment linkage system through the acquisition of treatment subsidies, and the linkage of resources at mediation level. As the attempt to integrate 'health, medical and welfare' with well-coordinated strategies and conditions showed the possibility of complementing the limitation of the health welfare support system in Korea, the extension of the related business was suggested. For this, it suggested the more stable stabilization of the linkage system and the improvement of the institutional aspect.
