  • The Community Health Service considers the family as a service unit and places the emphasis of its service on the health problems and the nursing needs of the family rather than the individual. From the conceptual point of view that tile community health service is both health maintenance and health promotion of the family, the community health nurse should have a knowledge of the growth and development of the family and be responsible for the comprehensive support of normal family development. The community health nurse often is in a position to make a real contribution to normal family development. In order to investigate the relationship between the areas of nursing need and family development, the following objectives were established 1. To discover the general characteristics of the study population by the stage of family development. 2. To discover specific nursing needs in relation to the family developmental stage, and to determine the intensity of the nursing needs and the ability of the family to cope with these needs. 3. To discover overall family health nursing problems in relation to the family developmental stage and determine the intensity of the nursing need and the problem solving ability of family. Definitions : The family developmental stages as classified by Dually were used stage 1. Married couples(without children) stage 2. Childbearing Families (oldest child birth to 30 months of age) stage 3. Families with preschool children (oldest child 2½-to 6 years) stage 4. Families with schoolchildren (oldest child 6 to 13 years). stage 5. Families with teenagers (oldest child 13 to 20 years) stage 6. Families as launching centers (first child gone to last child′s leaving home). stage 7. Middle- aged parents (empty nest to retirement) stage 8. Aging family member (retirement to death of both spouses) The areas of nursing need were defined as those used in the study, "A Comprehensive Study about Health and Nursing Need and a Social Diagram of the Community", by tile Nursing research Institute and Center for population. and Family Planning, July 1974. The study population defiled and selected were 260 nuclear families ill two myron of Kang Hwa Island. Percent, mean value and F- test were utilized in tile statistical analysis of the study result. Findings : 1. General characteristics of the study population by tile family developmental stage ; 1)The study population was distributed by the family developmental stage as follows : stage 1 : 3 families stage 2 : 13 families stage 3 : 24 families stage 4 : 41 families stage 5 : 50 families stage 6 : 106 families stage 7 : 13 families stage 8 : 10 families 2) Most families had 4 or 5 members except for those in stage, 1, 7, and 8. 3) The parents′ present age was older in the higher developmental stage and their age at marriage was also younger in the higher developmental stages. 4) The educational level of parents was primarily less than elementary school irrespective of the developmental stage. 5) More than half of parents′ occupations were listed as laborers irrespective of the developmental stage, 6) More than half of the parents were atheists irrespective of the developmental stage. 7) The higher the developmental stage(from stage 2 to stage 6 ), the wider the distribution of children′s ages. 8) More than half of the families were of middle or lower socio-economic level. 2. Problems in specific areas of nursing need by family developmental stage, the intensity of nursing need and the problem solving ability of the family : 1) As a whole, many problems, irrespective of the developmental stage, occurred in tile areas of Housing and Sanitation, Eating Patterns, Housekeeping, Preventive Measures and Dental care. Problems occurring ill particular stages included the following ; stage 1 : Prevention of Accident stage 2 : Preventive Vaccination, Family Planning. stage 3 : Preventive Vaccination, Maternal Health, Family Planning, Health of Infant and Preschooler. stage 4, 5 : Preventive Vaccination, Family Planning, Health of School Children. stage 6 : Preventive Vaccination, Health of School Children. 2) The intensity of the nursing need in the area of Acute and Chronic Diseases was generally of moderate degree or above irrespective of the developmental stages except for stage 1. Other areas of need listed as moderate or above were found in the following stages: stage 1 : Maternal Health stage 3 . Horsing and Sanitation, Prevention of Accident. stage 4 . Housing and Sanitation. stage 5 : Housing and Sanitation, Diagnostic and Medical Care. stage 6 : Diagnostic and Medical care stage 7 : Diagnostic and Medical Care, Housekeeping. stage 8 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Dental Care, Eating Patterns, Housekeeping. 3) Areas of need with moderate problem solving ability or less were as follows : stage 1 : Diagnostic and Medical Care, Maternal Health. stage 2 : Prevention of Accident, Acute and Chronic Disease, Dental Care. stage 3 : Housing and Sanitation, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of Infant and preschooler, Eating Patterns. stage 4 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of New Born, Health of Infant and Preschooler, Health of school Children, Eating Patterns, Housekeeping. stage 5 . Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Preventive Vaccination, Maternal Health, Eating Patterns. stage 7, 8 : Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measures, Dental Care, Preventive Vaccination, Eating Patterns , Housekeeping. Problem occurrence, the degree of nursing need and the degree of problem solving ability 1 nursing need areas for the family as a whole were as follows : 1) The higher the stages(except stage 1 ), the lower the rate of problem occurrence. 2) The higher the stage becomes, the lower the intensity of the nursing need becomes. 3) The higher the stages (except stages 7 and 8), the higher. the problem solving ability. Conclusions ; 1) When the nursing care plan for the family is drawn up, depending upon the stage of family development, higher priority should be give to nursing need areas ① at which problems were shown to occur ② where the nursing need is shown to be above moderate degree and ③ where the problem solving ability was shown to be of moderate degree. 2) The priority of the nursing service should be Placed ① not on those families in the high developmental stage but on those families in the low developmental stage ② and on those areas of need shown in stages 7 and 8 where the degree nursing need was high and the ability to cope low.

  • The job related activities of sixty nine nurses, working in the emergency rooms of three university hospitals, were analyzed for six days according to preestablished checklist of nursing activities ; the frequency of these activities and the amount of time spent in each specific nursing activity. The established checklist was monitored every five minutes for the duration of the duty autu, thus producing 414 items of data. The data were not gathered on consecutive days but over the period of one month from May 6, 1994 to June 5, 1994. The following conclusions are derived from analysis of the data : 1. Twelve categories of nursing activities were obtained : The primary activity was communication related to the patient and all information pertaining to the patient. Other activities included maintaining the patient's record, observation and assessment of the patient, cooperation with other medical personnel, management of equipment and drugs, procedure and treatment, specimen collection, consultation and education for the patient, including drug management and personal hygiene and any other relevant education to the patient's condition. 2. The average frequency of categorized nursing activity can be classified as follows : communication related to patient was the highest at 17.6 times. The next was maintaining the patient's record at 17.3 times. The observation and assessment occurred 16.9 times. Consultation and education for patients and family, 8 times, medication, 5.7 times, and procedures and treatments, 6 times. 3. The average time required for each activity was as follows : 230.1 minutes (or maintaining the patient's record, 204.9 minutes for communication related to the patient, 199.2 minutes for observation and assessment, 71.2 minutes for medication, 66 minutes for consultation and education of the patient and family, and 51.8 minutes for procedures and treatment. 4. The most demanding nursing activity in the emergency room for the nurse was answering questions from the patient's family, maintaining communication between the medical staff, maintaining and reviewing the patient's charts, writing prescriptions and monitoring 1. V. infusion rates. 5. The most time consuming nursing activities for the emergency room nurse include maintaining and following the patient's charts, communication between the medical staff, answering questions from the patient's family, observation of the patient and relaying all of the appropriate patient information to the incoming nurses during a shift change. 6. The F-test was administered to measure the required time for the categorized nursing activities according to day, evening, and night-shift nurses. There were significant differences (p<.05) in specimen collection, observation and assessment, cooperation between medical staffs, personal hygiene, communication related to patient, education and re-search. Posterior multiple comparison test showed that specimen collection, cooperation between medical staffs and personal hygiene were mostly done by the evening-shift nurses. Also most observations and assessments were done by the night-shift nurses. Education and communication to patients were done by day-shift nurses. Thus there were significant difference between shifts for the main nursing activities. So there should considev a reallocation of the duty of nurses on each shift. 7. The F-test also indicated that there wes a similarity in time duration for procedures and treatments and for cooperation between medical staff and nurses in all three hospitals. However, the remaining categories of nursing activities also showed a significant difference between the three hospitals. This indicated that there were differences in each emergency room that influence time for each categorized nursing activities and this should be given more consideration. Recommendations : 1. A seasonal difference should be considered in the activities of nurses in the emergency room and a comparative analysis should be carried out to deter-mine seasonal differentiation. 2. A study on more objectively measurable nursing activities should be administered as well as one determining the subjective responds towards nursing activities in the emergency room.

  • 최근 영상 의학 분야의 발전으로 인한 보편화와 일본의 후쿠시마 원전사태가 일어나면서 방사선 노출에 대한 대중들의 관심이 높아지게 되었다. 이러한 방사선 피폭에 대한 대중들의 관심으로 현재 거의 대부분의 PET/CT검사에서 사용되고 있는 AEC (Automatic Exposure Control) 시스템은 환자의 피폭선량 감소를 위해 피사체의 두께에 따라 최적의 관전류를 조사한다. 또한, 서울아산병원에서는 전신 PET/CT 검사 시선속 경화 인공물(Beam hardening artifact)의 발생을 줄이기 위해 환자의 팔을 머리 위로 올리고 검사를 시행하고 있다. 본 연구에서는 전신 PET/CT검사 시 환자의 팔 위치에 따라 AEC 시스템을 적용한 CT 유효선량의 차이를 비교하고자 한다. 2008년 12월부터 2011년 7월까지 서울아산병원 핵의학과를 내원하여 동일 장비에서 팔을 올렸을 경우와 팔을 내렸을 경우의 전신 18F-FDG PET/CT 검사를 시행한 환자 45명을 연구의 대상으로 하였고, 실험 장비는 Biograph Truepoint 40 (Bio 40), Biograph Sensation 16 (Bio 16), Discovery STe 8 (DSTe 8)을 사용하였다. 각 장비당 15명의 동일 환자를 대상으로, 팔을 올리고 검사하였을 경우와 팔을 내리고 검사하였을 경우의 CT 유효선량을 산출하여 비교 분석하였다. CT 유효선량의 측정 방법은 ImPACT v1.0 프로그램을 사용하였다. 이 연구를 통해 팔을 올리고 검사한 경우에 팔을 내리고 검사한 경우보다 총 15.2%의 환자 유효선량이 감소된 것을 확인할 수 있었다. 전신 PET/CT 검사 시 환자의 팔을 올린 자세는 선속 경화 인공물 발생을 줄이고, 영상의 질을 향상시킬 수 있을 것이라 생각된다.

  • 서론: 종래의 PET 영상 재구성에 있어서 FBP 등에 비해 3차원 반복 재구성 방법이 일반적으로 대체하고 있으며, 이것은 검출기 기하학적 특성과 완벽한 3차원 산란 평가 및 저잡음 randoms 평가 등의 더 진보된 재구성 알고리즘을 제공하고 활용되고 있다. 최근에 SharpIR알고리즘은 3차원 반복 재구성 알고리즘으로 PET 검출기 응답 정보를 통합하여 PET 영상의 잡음을 효과적으로 감소시켜 대조도를 향상 시키기 위한 것으로 알려지고 있다. 본 연구에서는 새로운 반복 시스템 모델인 SharpIR에 대한 성능 평가와 임상에서의 적용 가능성에 대해 알아보고자 한다. 실험재료 및 방법: 검출기 응답에 대한 분해능을 측정하기 위해 유리관(내경 1.1 mm, 두께 0.2 mm)에 $^{18}F$-FDG (250 MBq/mL)을 주입하여 축 방향 시야의 중심과 축 방향으로 5, 10, 15, 20 cm만큼 떨어진 지점에서 획득하였고 VUE point HD와 VUE point HD-SharpIR로 재구성하여 각각의 영상에서 반치폭을 구하였다. 또한 영상품질평가로 image quality phantom (NU2-2001)을 이용하여, 여러 개의 각각 다른 반지름을 가지는 원형구에 cold (직경 28, 37 mm)와 ho (직경 10, 13, 17, 22 mm)부분을 나누어 배경잡음을 주고 영상의 대조도를 평가하였다. 획득된 영상은 VUE point HD와 VUE point HD-SharpIR로 재구성을 하였다. 임상실험에서는 전신검사를 시행받은 환자 중 병소가 있는 환자 10명을 대상으로 VUE point HD와 VUE point HD-SharpIR로 재구성하였다. 이때 iterations을 1~10까지 변경하여 병소 부위와 간 부위에 관심영역을 설정하여 대조도를 평가하였다. 결과: VUE point HD로 재구성한 영상에서는 시야 중심으로부터 축방향 거리 증가와 함께 반치폭이 함께 증가하였지만 VUE point HD-SharpIR로 재구성한 영상에서는 거리가 증가하여도 일정한 반치폭을 나타냈다. 대조도는 팬텀 실험과 임상 실험에서 VUE point HD-SharpIR이 VUE point HD보다 대조도의 향상을 나타냈다. 결론: 검출기 시스템 응답에 대한 더 많은 정보를 포함시킴으로써 SharpIR 알고리즘은 VUE point HD에서 사용되는 기본 모델의 정확성을 향상시켰다. 또한 SharpIR은 VUE point HD보다 각각의 복셀에 관련된 더 많은 측정 위치를 가지는 시스템 모델이기 때문에 더욱 정교한 재구성 모델의 결과를 나타내기 위해 더 많은 반복이 걸린다. 결론적으로 SharpIR은 PET 영상에서 대조도를 향상시켰고 임상에서 적용할 수 있는 최적화된 재구성 조건을 알아보기 위해 종단적 연구를 통해 적용한다면 임상에서 유용하게 사용될 것이다.

  • 본 논문에서는 국내 의료기관 종사자 중 핵의학과 종사자 일부를 선정하여 방사성동위원소에 의한 체내오염 여부와 정도를 정량적으로 측정한 후 그 결과에 근거하여 선량을 평가하였다. 선량평가를 위해 서울시내에 소재하는 대형병원 3곳의 핵의학과 종사자 25명을 측정 대상자로 선정한 후 각 개인의 소변시료를 채취하여 측정하였다. 시료는 주 1회 채취하였으며 종사자에 따라 6~10회에 걸쳐 각 회당 100~200 mL 정도의 양을 채취한 후 고순도게르마늄반도체검출기를 사용하여 시료를 측정 하였다. 측정된 결과에 근거하여 방사성동위원소의 섭취량을 평가하였고 예탁유효선량을 평가하는 도구로 IMBA 전산프로그램을 사용하였다. IMBA 프로그램으로 평가가 불가능한 반감기가 매우 짧은 $^{99m}Tc$, $^{123}I$ 등과 같은 핵종에 의한 선량은 국제원자력기구에서 권고하는 방법을 적용하여 선량을 평가하였다. 채취한 소변시료를 대상으로 방사성핵종을 계측, 분석한 결과 $^{99m}Tc$, $^{123}I$, $^{131}I$, $^{201}Tl$ 핵종 등이 검출되었고 양전자방출단층 촬영에 사용되는 $^{18}F$ 핵종도 검출되었다. 계측된 결과로부터 평가된 예탁유효선량은 0~5 mSv의 분포를 보였으나 대부분 1mSv 미만으로 나타났다. 1 mSv를 초과한 종사자는 모두 3명으로 이들 모두는 선원의 분배와 취급에 직접적으로 참여한 종사자들이었고 간호사의 경우 1 mSv를 초과한 사람이 한 사람도 발생하지 않았다. 그러나 보다 정확하고 상세한 결과를 도출하기 위해서는 계절적 요인을 구분하기 위한 장기적인 연구가 필요하며 측정대상자의 수를 확대할 필요가 있을 것으로 판단된다. 현재로서는 대부분의 핵의학과 종사자들은 방사성 핵종에 의한 체내오염 정기 감시를 실시할 필요가 없을 것으로 여겨지며 그에 따른 방사선학적인 건강상의 영향도 우려할 필요가 없는 것으로 판단되지만 불필요한 소량의 피폭이라도 줄이기 위해서는 주기적으로 작업환경을 측정하거나 공기 중 방사성핵종 농도 감시를 가능한 한 자주 실시하는 것이 바람직 할 것으로 판단된다.

  • This study was conducted to measure the effects of clinical application of a Nursing Diagnosis Protocol. The dependent variables were the degree of patient's satisfaction and the degree of nurse's satisfaction with the nursing activity. Analysis of the effect of the use of the nursing diagnosis protocol was based on the nursing record. The subjects for this study were 61 nurses(experimental group 31, control group 30) and 155 patients (experimental group 55, control group 100) on four internal medicine wards in K University Hospital in Seoul. Data collection was done from August to October 12,1988. The results obtained in this study can be summarized as follows, 1, Effect of the clinical application of the nursing diagnosis protocol. 1) The first hypothesis ; “nurses who use the nursing diagnosis protocol will have higher degrees of satisfaction than those who use traditional methods” was rejected (t=.54, df=58, p=.59). 2) The second hypothesis ; “patients nursed by nurses using the nursing diagnosis protocol will have higher degrees of satisfaction than those nursed with traditional methods” was supported(t=1.93, df=154, p=.05). 3) The third hypothisis : Major hypothesis ; “the nursing records of the experimental group, who used the nursing diagnosis protocol, will be more detailed than those of the control group” was supported (t=6.40, df=79.90, p=.000). (1) The first subhypothesis ; “The recorded data collection of the experimental group will be more detailed than that of the control group” was rejected (t=1.79, df=118, p=.07). (2) The second subhypothesis ; “The recorded patient's problem statement of the experimental group will be more detailed than that of the control group”, was supported. (3) The third subhypothesis ; “The nursing record of the experimental group will be more convenient for implementation than that of the control group” was supported. 2. Factors related to the nurse's degree of satisfaction with protocol. 1) No general characteristics(age, religion, education level, duty career, present duty career) were related to the nurse's degree of satisfaction. 2) Variables related to the nurse's degree of satisfaction were “satisfaction as a nurse” and “consider nursing as lifelong job” (t=-2.6, df=13.22, p=.02, t=2.41, df=23.85, p=.02). 3. Factors related to the patient's degree of satisfaction. 1) General characteristics related to the patient's degree of satisfaction with nurses using the protocol were age, educational level, and being married.(F=5.17, df=3/153, p=.00, t= -2.39, df=154, p=,01, f=5.91, df=2/153, p=.00) 2) The variables previous hospitalization, duration of hospitalization, the hospital unit presence of a relative, medical insurance, or medical diagnosis were not related to the patient's degree of satisfaction. 1. The experimental group's nursing record was more detailed than the control group's record with regard to the physical and psychological state of the patients. As noted above, the experimental group nurses, who use a nursing diagnosis had protocol were less satisfied than the control group who used traditional methods of the recording, but experimental group patients had a higher degree of satisfaction than the control group patients. The nursing records of experimental group, using the nursing, diagnosis protocol was more detailed than that of the control group. If the nursing diagnosis protocol is used in clinical nursing practice, the quality of nursing care may be improved.

  • 이 연구의 목적은 학습자의 성격유형과 불일치 상황 제시 방법에 따라 유발된 인지갈등 정도를 비교해 보는 것이다. 학습자의 성격유형검사 도구는 MBTI를 사용하였고, 검사 결과를 이용하여 학습자의 성격유형은 선호지표별 선호 경향과 성격 기능 유형의 두 가지 측면에서 다루었다. 불일치 상황 제시는 시범실험을 통한 현상제시와 논리문을 읽게 하는 논리제시, 두 가지 방법을 사용하였으며, CCLT를 사용하여 인지갈등 정도를 측정하였다. 연구대상은 고등학생 461명이며, 개념검사 문항은 용수철저울의 양쪽 무게가 2N인 추를 매달았을 때, 저울의 눈금이 어떻게 나타날지를 묻는 문항이었다. 연구 결과, 학습자의 성격유형에 따라서 인지갈등의 정도는 차이가 있는 것으로 나타났다. 성격유형을 선호지표로 나누었을 때, 사고형(T) 판단을 하는 학습자는 감정형(F) 판단을 하는 학습자에 비해 인지갈등이 크게 일어났으며, 성격유형을 성격 기능유형으로 나누었을 때는 감각감정형(SF)인 학습자가 인지갈등이 가장 작게 일어나고, 직관사고형(NT)인 학습자가 인지갈등이 가장 크게 일어났다. 또한 불일치 상황의 제시 방법에 따른 인지갈등 정도는 학습자의 성격유형에 따라 다르게 나타날 수 있음을 확인하였다. 성격 유형에 따라 다르게 나타날 수 있음을 확인하였다. 전체적으로는 현상을 제시하여 인지갈등을 유발한 경우가 논리를 제시한 경우데 비해서 더 클 인지갈등을 유발시켰다. 하지만 J.P 선호지표가 판단형(J)인 학습자는 논리제시와 현상제시에서 인지갈등 정도가 비슷했으며나, 인식형(P)인 학습자는 현상제시를 사용했을 때가 논리제시를 사용했을 때보다 인지 갈등이 효과적으로 일어났다. 이상의 연구결과를 통해 학습자의 성격특성은 인지 갈등의 유발에 영향을 줄 수 있으며, 학습자의 성격유형에 따라서 인지갈등을 보다 효과적으로 일어나게 하는 불일치 상황 제시 방법이 있음을 확인하였다.

  • Support has always been considered an important nursing concept. However, there is no agreement among nurse researchers as to a conceptual definition of supportive nursing or meaningful supportive behaviors. Clarification of the concept, support in nursing, is necessary to promote communication among nurses on nursing behaviors that are effective in providing support and on understanding the relevant properties and charcteristics of the concept, supportive nursing care. The objectives of the study were : 1. to analyse the concept, support in nursing, in order to provide a definition of supportive nursing care, and 2. to operationalize the definition of supportive nursing care and use it as an experimental nursing intervention for patients with low back pain. The first part of the study used the concept analysis approach developed by Walker and Avant(1983) to define the concept of supportive nursing care. The properties of supportive nursing care, defined by this analysis, included perception of supportive need, reciprocal interaction(Transaction), listening, providing empathy and information related to health, and confirmation of the patient's verbal and non - verbal response. The second part, the experimental part of the study, was done using King's(1970) Interpersonal Theory for Nursing. The concept, supportive nursing care, as defined in the concept analysis was operationalized and used as the experimental intervention. The experiment tested the effectiveness of the independent variable, supportive nursing care on the dependent variables, depression, mood and patient satisfaction, in the patients with low back pain in army hospitals. The instruments used to measure the dependent variables were Zung's(1965) Self- Rating Depression Scale, Ryman and Colleagues'(1974) Mood Questionnaire and LaMonica and Colleagues'(1986) Patient Satisfaction Scale. The experimental design used for this study was a Solomon 4 group experimental design. This design has the strength of allowing for observation of the main effects of supportive nursing care and pretesting, and for observation of the interaction effects of pretesting and supportive nursing care. The design includes one experimental group and three control groups. The Subjects of this study were 150 young male patients with low back pain on Neuro - Surgical Wards in three general army hospitals. There were 35 in the experimental group, 39 in the pre - posttest control group, 36 in the treatment - posttest control group and 40 in the posttest only control group. Supportive nursing care, as operationalized by the researcher according to the concept analysis, was given to the patients in the experimental group and the treatment -posttest control group, individually for 30 minute sessions, every other day for 5 days. Data collection was done using a questionnaire. The data were collected in a pretest one week before the supportive nursing care sessions, a posttest immediately after the sessions and follow- up test one week later. Hypotheses testing was done using 2×2 factorial analysis of variance and Meta analysis(Stouffer's Z method). The results of this study are summarized as follows : 1. Hypothesis Ⅰ, “There will be a difference on depression level between the patients with low back pain who receive supportive nursing care and those who do not receive supportive nursing care”, was supported (F=8.49, p<.05). 2. Hypothesis Ⅱ, “There will be a difference on mood level between the patients with low back pain who receive supportive nursing care and those who to not receive supportive nursing care”, was supported (Z meta=2.17, p<.05). 3. Hypothesis Ⅲ, “There will be a difference on satisfaction level between the patients with low back pain who receive supportive nursing care and those who do not receive supportive nursing care”, was supported (F=13.67, p<.05). 4. ANOVA, done to examine the interaction effect of history and maturation, showed no significant difference on the dependent variables between the observations of the pretest scores of the experimental group, the pretest scores of the pre- posttest control group and the posttest score of the posttest only control group. 5. To test for continuing effect of supportive nursing care, paired t-test was done to compare the scores for the dependent variables at the posttest and at the one week later follow-up test. No significant difference on the scores for the dependent variables was found between the posttest scores and the follow-up test scores for the two groups that received supportive nursing care, the experimental group and the treatment-posttest control group. In conclusion, it was found that in the case of young soldiers with low back pain in army hospitals, their depression level was decreased, their mood state was changed positively and their satisfaction level was increased by receiving supportive nursing care. Further, the effectiveness of the supportive nursing care lasted for at least one week in this study. The significance of this study to nursing is in the analysis of the concept of supportive nursing care and the demonstration of the effectiveness of supportive nursing care as an intervention within the limits of the study.

  • 레진계열의 심미성 수복재는 구성성분에 따라 각기 다른 특성과 물리적 성질을 나타낼 뿐만 아니라, 수복물 주변의 환경도 물성에 많은 영향을 미친다. 특히 수분의 흡수는 수복재 물성 변화에 큰 역할을 하며, 재료의 조성과 친수성 정도, 경화기전, 침지기간과 배지 등의 다양한 요소와 관련되어 수복재마다 각기 다른 양상을 나타낸다. 본 연구의 목적은 임상에서 많이 이용되고 있는 레진계열의 수복물 중에서 복합레진, 레진변형 글라스아이오노머 및 콤포머의 침지기간에 따른 수분흡수도와 압축강도의 변화를 계측하여 비교하고, 수분흡수도와 압축강도 간에 나타나는 상관관계를 밝히고자함이다. 복합레진으로는 Z-100(3M, U.S.A.), 콤포머는 F-2000(3M, U.S.A.), 레진변형 글라스아이오노머는 Vitremer Restorative(3M, U.S.A.)를 이용하여 수분흡수도와 압축강도 측정을 위한 시편을 각각 제작하였다. 각 시편을 1일, 2주, 4주, 8주간 $37^{\circ}C$ 증류수에 넣어 보관한 후 수분흡수도는 침지 전과 후의 질량차를 부피로 나눈 값으로 산출하고, 압축강도는 Instron(Instron Corporation Headquarters, U.S.A.)을 이용하여 측정한 후 다음과 같은 결과를 얻었다. 1. 세 가지 수복재 모두 침지기간이 길어짐에 따라 수분흡수도가 증가하였으며 수분흡수의 대부분은 초기 2주 동안에 나타났다(P<0.001). 2. 레진변형 글라스아이오노머의 수분흡수도가 복합레진과 콤포머에 비해 상대적으로 크게 나타났다. 3. 세 가지 수복재 모두 침지시간에 따라 압축강도가 감소하였으며(복합레진과 콤포머: P<0.001, 레진변형 글라스아이오노머: P<0.05), 특히 복합레진이 다른 재료에 비해 가장 큰 감소 경향을 나타냈다. 4. 세 가지 수복재 모두 수분흡수도가 증가함에 따라 압축강도가 감소하였다(P<0.05).
