        하악 소구치용 post and core systems의 치근 내부 응력분산 효과에 대한 유한요소법적 연구

        홍현자,전영찬,정창모,Hong, Hyun-Ja,Jeon, Young-Chan,Jeong, Chang-Mo 대한치과보철학회 1995 대한치과보철학회지 Vol.33 No.3

        The purpose of this study was to analyze the stress distribution in the dentin and post structures by the various post core materials and the amount of remaining coronal tooth structures. The 2-dimensional finite element models of mandibular 2nd premolars was divided into seven types according to the various amount of remaining coronal tooth structures. All types were modeled using equal length, diameter and shape of the post. 2 types of post and core materials were used : 1) cast gold post and core 2) stainless steel post and compsite resin core 10 Newton force was applied as follows 1) vertical force on occlusal fossa 2) $45^{\circ}$ oblique force on buccal surface of buccal cusp tip The results were as follows : 1. There was no apparent difference in the pattern of stress distribution according to the amount of remaining coronal tooth structure. 2. There was no apparent difference in the pattern of stress distribution within the dentin according to the post and core materials. A cast gold post and core generated lower dentin stress than a stainless steel post and resin core. 3. Max. dentinal stress resulting from vertical force was observed in the lingual side of dentin around the crown margin.This stress resulting from oblique force was observed in the lingual root surface of alveolar bone crest level.

      • 호스피스 환자의 돌봄 요구와 가족이 인지하는 환자의 돌봄 요구 비교: Q 방법론

        용진선,홍현자,Yong, Jin-Sun,Hong, Hyun-Ja 한국호스피스완화의료학회 2004 한국호스피스.완화의료학회지 Vol.7 No.2

        목적: 본 연구의 목적은 호스피스 병동에 입원한 호스피스 환자들의 돌봄 요구 유형과 가족간호자가 인지하는 환자의 돌봄 요구 유형을 파악하고, 두 군 간에 차이가 있는지 비교하여 호스피스 환자의 돌봄 요구를 만족시키기에 도움이 되는 방법을 모색하는데 필요한 기초 자료를 제공하고자 한다. 연구방법으로는 개인에 대한 내적 의미에 중심을 두고 인간의 주관성이나 태도 유형을 심층적으로 측정할 수 있는 연구 방법론인 Q방법론을 적용하였다. 방법: 본 연구를 위한 Q표본은 호스피스 환자들의 돌봄 요구에 대한 경험으로 구성된 23개의 진술문이다. 자료는 2002년 12월부터 2003년 2월까지 23개의 Q-표본을 이용하여 C 대학 K 병원 호스피스병동에 입원하고 연구에 동의한 환자 20명군과 이들을 간호하는 주 가족간호자 20명군으로 가족 20쌍의 P-표본으로부터 각각 수집하였다. 탈분포도는 정상 분포방식에 따라 9점 척도 상에 대상자의 의견과 일치하는 정도에 따라 분류하도록 하였으며, 면담시 대상자의 구술도 기록하였다. 자료 분석은 Quanl PC 프로그램을 통한 Q요인분석인 주인자 분석방법을 이용하여, 요구 유형을 파악하기 위하여 평균분석, 요인 가중치, 영역별 요인 분석, 요인 배열을 하였고, 요인수의 결정을 위해 아이겐값은 1.0 이상을 기준으로 하였다. 결과: 연구결과 호스피스 환자 군과 가족간호자 군이 인지한 호스피스 환자의 돌봄 요구 유형은 네 가지로 확인되었다. 신체적, 정서적, 영적, 그리고 사회적 돌봄 요구 유형. 돌봄 요구 유형에 대한 두 군 간의 전체 일치률은 48%이었다. 제 1유형은 '신체적 돌봄 요구형' 으로 통증조절이 안된 상태로 통증으로 인하여 심한 고통을 당하고 있어 주호소인 통증 및 신체적 안위에 대한 돌봄을 우선적으로 요구하였다. 두 군 간의 일치율은 62.5%이었다. 제 2유형은 '정서적 돌봄 요구형' 으로 가족과 친밀감과 사랑을 나누기를 원하고 죽음에 대한 두려움을 따뜻한 대화로써 정서적으로 지지 받기를 원하였다. 두 군 간의 일치율은 20%이었다. 제 3유형은 '영적 돌봄 요구형' 으로 대상자 모두 종교를 가지고 신심이 깊었으며 절대자에게 용서 받고 싶은 욕구가 많았고 기도와 사목자의 방문을 원하였다. 두 군 간의 일치율은 60%이었다. 제 4유형은 '사회적 돌봄 요구형'으로 자신이 하던 일에 대한 마무리와 봉사를 원하는 것으로 나타났다. 두 군 간의 일치율은 50%이었다. 이상으로 볼 때, 호스피스 환자와 가족간호자가 인지한 환자의 돌봄 요구는 큰 차이가 있다는 것을 알 수 있다. 따라서, 호스피스 간호사는 호스피스 환자의 돌봄 요구를 만족시키기 위해서 환자와 가족간호자간에 환자의 돌봄 요구에 대한 인지의 차이를 좁히기 위한 적절한 방법을 모색하고, 가족간호자에게 환자의 돌봄 요구를 사정하기 위한 교육을 시켜야 하겠다. Purpose: The purpose of tile study was to identify types of care needs of hospice patients and those from the family caregivers' perspective and to compare these two groups in reporting patients' care needs through Q-methodology. Methods: Twenty three Q-statements concerning care needs were selected through in-depth interviews of hospice patients. Data were collected from 20 hospice patients as well as 20 family caregivers respectively by sorting 23 Q-statements into 9 points standard. Data analysis was performed by using PC QUANL program. Results: Principal component analysis identified four types of care needs of the hospice patients. Overall, the accuracy of family caregiver reports was 48% in all types of care needs. Type 1 was named 'physical care needs type' for those whose greatest need was physical care to be free of pain and comfortable. The accuracy in Type 1 was 62.5%. Type 2 was named 'emotional care needs type' for those who would like to share love and intimacy with their family members. The accuracy in Type 2 was 20%. Type 3 was named 'spiritual care needs type' for those who would like to receive forgiveness from their God and prayers and visitation of clergy. The accuracy in Type 3 was 60%. Type 4 was named 'social care needs type' for those who would like to complete their ongoing work and to give service to others. The accuracy in Type 4 was 50%. Conclusion: There was a great difference between hospice patients and the family caregivers in reporting patients' care needs. Thus, hospice nurses need to educate family caregivers to more accurately assess patients' care needs.

      • 가족이 인지한 호스피스 환자의 간호요구 : Q방법론 적용 Q Methodology

        용진선,한성숙,홍현자 가톨릭대학교 간호대학 호스피스 교육연구소 2003 호스피스논집 Vol.7 No.-

        Purpose: The purpose of the study was to identify types of care needs of hospice patients from the family caregivers perspective through Q-methodology. Method: Twenty three Q-statements concerning care needs were collected through in-depth interviews of hospice patients. Data were collected from twenty family caregivers by sorting 23 Q-statements into 9 points standard from December 2002 to February 2003. Date analysis was performed by using a QUANL program. Result: Principal component analysis identified five types of care needs of the hospice patients which family caregiver perceived. Type 1 was named 'physical care needs type' and family caregivers perceived that their patients greatest need is physical care to be painless and comfortable. Type 2 was named 'care needs type for the future life after death' and family caregiver perceived that their patients need spiritual care for having hope about the next world. Type 3 was named 'emotional care needs type' and family caregivers perceived that their patients need emotional care for opening their minds and becoming stable. Type 4 was named 'religious service needs type' and family caregivers perceived that their patients need to have religious services such as mass, receiving prayers and the sacraments. Type 5 was named 'social care needs type' and family caregivers perceived that their patients need encouragement to go beyond themselves and to give loving services to others. In summary, family caregivers perceived that care for patients 'physical comfort is the priority. After achievingphysical care, family caregivers could perceive other aspects of care such as spiritual, social, and emotional care needs. In conclusion, we need to conduct further research to compare these results with the care needs of hospice patients themselves.

        병원에서의 간호사 역할확대 방안연구 : -병원행정직 간호사를 중심으로-

        임난영,성영희,홍현자,황문숙,김명애,곽월희,송경자,이미경 병원간호사회 2011 임상간호연구 Vol.17 No.3

        Purpose: The purpose for this study was to identify the present working status and tasks of nurse administrators in response to requirements of expanding nurses' roles in hospitals. Methods: The design of the study was descriptive-exploratory. The participants were 338 registered nurses who were working in hospital admini­strative departments. The data were collected from January 17, to March 20, 2011, and analyzed with descriptive statistics. Results: The majority of nurse administrators worked in quality assurance departments while no nurse administrators assigned in finance/taxation departments. Duties of nurse administrators were developed as 117 tasks in 11 divisions. Conclusion: These results suggest that expanding nurses' roles require developing job descriptions, nursing curricula emphasizing hospital administration, positive relationships with other health professions and a supportive system.
