  • 하악 제 1대구치에 티타늄과 지르코니아 소재의 기성 지대주와 맞춤형 지대주를 이용해 지르코니아 크라운으로 수복한 경우를 3차원 유한요소법을 통해 응력 분포를 분석해 보고, 피로 파절 강도 및 파절 형태를 고찰해 보았다. 정상교합자의 CT scan을 재구성한 하악골 모형상에 제 1대구치 임플란트 지지 지르코니아 크라운으로 수복한 6가지 유한요소 모형을 제작하고, 협측 교두 중앙에 수직과 30도 각도로 100 N의 하중을 가하는 조건으로 응력분포를 분석하였다. 현재 임상적으로 사용되고 있는 4가지 지대주를 이용하여, 군당 10개의 시편을 제작하고, ISO 14801에 따라 피로파절 실험을 실시하였다. 지대주나 고정체의 재질에 따른 응력분포의 차이는 없었고 형태에 따른 응력크기의 차이만 보였다. 맞춤형 지대주 군이 전반적으로 낮은 크라운 응력을 나타내었으며, 지대주 일체형 지르코니아 임플란트는 계면 골조직의 응력이 가장 낮게 나타났다. 피로수명의 평균값은 7군이 가장 높았고, 1군, 2군, 3군의 순서로 낮게 나타났으며(P<0.05), 기성 지대주 군은 피로수명의 편차가 적게 나타났다. 구치부의 임플란트 수복 시에는 맞춤형 지대주의 사용이 상부 보철물의 파절저항성 향상에 유리하며, 심미적 요구도가 높은 경우에는 고정체와의 접합부를 티타늄으로 제작한 지르코니아 맞춤형 지대주의 사용을 고려해 볼 만 하다.

  • Purpose : The aim of this study was to evaluate the survival rate of sintered porous-surfaced implants placed in the edentulous posterior mandibles, in relation to implant length and diameter, crown-to-implant ratio, and types of prostheses, for a maximum of eight years of functioning. Material and Methods : The study group consisted of 43 partially edentulous patients who visited Catholic University Hospital of Daegu and one private dental clinic. A total of 122 sintered porous-surfaced implants n $Endopore^{(R)}$ (Inn ova Life Sciences, Toronto, Ontario, Canada) -- were placed in the edentulous posterior mandibles, Two diameter sizes (4.1 mm and 5.0 mm) and four lengths (5.0 mm, 7.0 mm, 9.0 mm, and 12.0 mm) were used. One hundred and three implants were splinted and 21 implants were nonsplinted. The survival rates of the implants in relation to length, diameter, crown-to-implant ratio, and types of prostheses were investigated. Statistical data were analyzed using SPSS Win.Ver 14.0 software with the Chi-square test. Results : The survival rate of the 4.1mm diameter implants was 100% and 91.2% for the 5.0mm diameter implants. The survival rates of the implants of differing diameters were found to be statistically different (p=0.005). The survival rates of both the 5.0mm and 7.0 mm length implants were 100%. The survival rate of the 9.0mm length implants was 97.9% and for the 12.0mm length implants was 95.1%. There was no statistical difference in survival rates for the differing lengths of implants. Of the 103 prostheses that were splinted, the survival rate was 98.0%. The survival rate of splinted prostheses was higher than that of the non-splinted prostheses, but was found to be not statistically different. There were no failed cases when the crown-to-implant ratio was under 1.0. When the crown-to-implant ratio was between 1.0 and 1.5, the failure rate of the implants was 6.7%. No failure was recorded with the ratio range of 1.5 to 2.0. Relative to the crown-to-implant ratio of 1.0, the failure rates were statistically different (p=0.048). Discussion and Conclusion : The cumulative survival rate of the porous-surfaced implants placed in the edentulous posterior mandibles was 97.5%. Short porous-surfaced implants showed satisfactory results after a maximum of nine years of functioning in the edentulous posterior mandibles.

  • Purpose: The purpose of this study is to understand and analyze the current status of dementia management and rehabilitation services in Busan, South Korea, in response to the rapid increase of people with dementia due to the aging of the population. Methods: To investigate the current status of dementia rehabilitation in Busan, a survey was disseminated to dementia safety centers and day- and night-care centers in 16 districts/counties in Busan. Of the 209 day- and night-care centers, 23 institutes were registered in the National Health Insurance Service and received the highest grade (Grade A) in the institute evaluation that was implemented in each district. A telephone interview was conducted, and survey questions were related to the existence of an ongoing dementia rehabilitation program, program presenter, number of participants, progress method, program time, program duration, program contents, and participation path. Results: Dementia safety centers were implementing dementia prevention program, cognitive enhancing program, dementia program, self-help meeting and education program for family of dementia patient. The majority of the presenters of all four dementia-related programs were occupational therapists. The highest number of participants in the dementia prevention program was 15, and the highest number of participants in the cognitive enhancing program, dementia program, self-help meeting and education program for family of dementia patient was 10. All institutes' programs delivered group therapy. As for the time and frequency of the program, most dementia program included three-hour sessions five times a week. Most dementia prevention program, cognitive enhancing program, self-help meeting and education program for family of dementia patient included 60-minute sessions once a week. The most frequently observed program duration for the dementia prevention program and cognitive enhancing program was six months, and the most frequently observed duration for the dementia program was three months. Lastly, study participants most often reported that self-help meeting and education program for family of dementia patient lasted for two months. Among day- and night-care centers in Busan, programs related to cognition were implemented in 18 institutes, and the majority of the program presenters were social workers. Conclusion: In response to the rapidly growing number of dementia patients due to the aging of the population, this study examined the current status of dementia rehabilitation in Busan. The study results underscore the need to develop systems that consider the circumstances in Busan and continuously and systematically support dementia programs.

  • 통증은 환자들로 하여금 내원하게 하는 주된 증상중의 하나로, 치료방법의 선택 및 효과 판정을 위해서는 적절한 평가가 필요하다. 통증은 실험적인 방법과 임상적인 방법에 의해 측정될 수 있는데, 통증의 주관적인 성격상 임상적인 방법이 일반적으로 사용된다. 통증의 임상적측정법은 일차원적측정법과 다차원적측정법으로 대별할 수 있는데, 일차원적 측정법으로는 시각적상사척도(Visual Analogue Scale), 구술적평정척도(Verbal Rating Scale), 수치평정척도(Numerical Rating Scale), 통증표정척도(Pain Faces Scale), 그리고 포커칩 도구(Poker Chip Tool)등이 있고, 다차원적 측정법으로는 McGill 동통질문서(McGill Pain Questionnaire), 다면적인성검사(MMPI), 통증행동척도(Pain Behavior Scale), 통증장애지표(Pain Disability Index), 그리고 통증평정척도(Pain Raing Scale)등이 있다. 일차원적 측정법은 주로 환자의 자가통증평가법에 기초하여 통증의 강도를 측정하는데, 측정방법의 단순함과 신속성으로 인해 급성통증을 평가하는데 주로 사용된다. 다차원적인 측정법은 통증의 주관적, 정신적 그리고 행동적인 면을 측정하는데, 측정방법이 포괄적이고 신뢰성이 있어서 만성통증을 측정하는데 사용된다. 환자의 언어와 인지능력은 정확한 통증을 평가하는데 장애가 되는 주된 요인이다. 통증에 따른 행동반응이나 생체반응은 환자의 통증을 완전히 대변하지 못하지만 이러한 상황에 있어 유용한 통증평가지표가 될 수 있다. 통증평가법을 결정할 때에는 먼저 측정하려고 하는 통증의 성격을 고려하여 어떠한 면을 측정할 것인가를 결정해야하며 아울러 환자의 언어와 인지능력을 고려해야 한다. 적절한 평가법의 선택은 환자의 진단과 치료에 있어 유효한 결론에 이르게 하는 중요한 과정이다.

  • 만성 통증(Chronic pain)은 병원을 찾는 가장 흔한 원인이고, 환자 자신뿐만 아니라 가족, 사회에까지 경제적 비용 문제를 야기한다. 본 연구는 국민건강영양조사 자료를 이용하여 우리나라 일반인의 근골계질환으로 인한 만성통증의 규모를 분석하고, 이들의 의료이용에 영향을 미치는 요인을 분석하였다. 본 연구는 5기 국민건강영양조사 자료를 이용하였고, 이중에서 20세 이상인 사람을 대상으로 분석을 하였다. 평가도구로는 EuroQoL-5 Dimension Index(EQ-5D)를 이용하였다. 통계분석은 t-test와 카이제곱 검정, 다중 로지스틱 회귀분석을 이용하여 분석하였다. 의료 이용에 대해서는 만성 통증이 있는 경우는 대조군에 비하여 의료이용을 하는 경우가 5.858배 높았으며 만성 통증 여부를 통제한 상태에서도 여자는 남자에 비하여 의료 이용을 하는 경우가 1.156배 높았다. 그러나 연령이나 직업, 가구 수입 여부는 통계적 유의성이 없었다. 만성 통증이 있는 경우는 삶의 질 역시 낮았는데, 만성 통증의 관리는 삶의 질을 높이고 의료이용을 억제하기 위하여 매우 중요한 역할을 한다고 할 수 있다. 마취통증의학과 의사는 진통제나 진경제와 같은 약물에 관해서도 해박하고 또한 숙련된 신경블록 기술도 가지고 있어 통증에 대해 다양한 방법을 구사할 수 있는 입장에 있다. 따라서 만성통증의 관리에 있어서 마취통증의학과의 역할이 중요하고 주도적으로 이루어질 필요가 있다.

  • Artemisinin, a new antimalarial to treat patients infected with strains of Plasmodium jalciparum, derived from the plant Artemisia annua Linn, has immunopharmacologic actions such as enhence the PHA -induced lymphocyte transformation rate, increased the weight of spleen but reduced the weight of thymus, reduced phagocytic function of peritoneal macrophage, remarkably reduced the level of serum IgG and hemolysin fonning capacity (sentitized with SRBC), inhibited the activity of Ts cells of donor mice by supraoptimal immunuization(SOI), but enhenced activity of Ts cells of recipient mice by SOI. These results suggested that Ts cells may be the target cells of artemisinin. To the serum complement C3 level of plasmodium berghei-infeted mice, artemisinin (i. m,) could remarkly increase it. The artemisinin also obviously reduced the prostaglandin E(PGE) in the mouse hind paw swelling induced by carrageenin. Numerous studies have demonstrated that pharmacologic doses of PGE attenuate the development of immunocomplex nephritis. Some autologous immune mechanisms may be invoolved In the pathogensis of some types of glomurulonephritis. Glomerular abnormalities can be induced in animals by variety of immunological manipulations. The resulting disorder has many clinical and pathogical similarities to the disease in human. Our purpose was therefore to test the ability of the artemisinin to lessen the severity of rabbit IgG accelerated nephrotoxic serum glomerulonephritis in mice model. Mice which had treated with rabbit IgG and NTS, administrated with saline, showed Significant inceases of urinary protein, cholesterol level, and decrease of serum albumin in NS group. On the contrary, By i.g. adminstration of artemisinin at dose of 12.5, 25 and 50 mg/kg for 14 days after NTS injection, shown that artemisinin inhibited the nephritic changes in some parameters by means of urinary protein(p<0.05, p<0.01) and serum choleterol(p<0.05, p<0.01) and albumin (p<0.05, p<0.01), blood urea nitrogen (p<0.05, p<0.01), serum albumin(p<0.05, p<0.01); Cyclophosphamide(i.p. 10mg/kg for 14d) had almost same effect as the artemisinin had. Morphological studies shown that The picture of kidney from the mouse with NTS-nephritis accerated with rabbit IgG, treated with i.g. saline as the control, the mesangiocapillary were enlarged and proliferated; There were inflammatory cells infiltrating around the glomeruli; The ethelial cell were proliferated in the wall of Bowman's capsule. Histopatholological picture of kidney from the NTS-nephritis accerated with rabbit IgG mouse treated with i.p. 10mg/kg cyclophosphamide as the positive control. No siginicant histopathological evidence were found. Treaded with i.p. 12.5mg/kg artemisinine, the picture shown that mesangiocapillary were lightly proliferated; There were inflammatory cells infiltrating around the glomeruli; Treaded with i.p. 25mg/kg artemisinine, The picture shown that the mesangiocapillary were lightly proliferated; Treaded with i.p. 50mg/kg artemisinine, The picture shown that both the mesangiocapillary proliferated and the inflammatory cells infiltrating around the glomeruli are less than treated with saline, 12.5 and 25 mg/kg artemisinine. On the basis of these studies we conclude that the artemisinin can relieve pathological change caused by NTS-nephritis aacerated with rabbit IgG.

  • 'What is nursing' this question could always be arised and such a question could bring forth the new possibility to definete the nursing concept more clearly. At the middle of 19th Centry, Mrs. Nightingale defined the concept of nursing as follows; 'Nursing is a kind of treatment act to aid the patient so that the health of patients may be recovered naturally, as keeping the most comfortable circumstances.' But after then, the role and function of nurses about purpose and method of nursing has continuously been studied, as the social circumstance has been changed. The fact that care provider and client have the same concept about nursing is very important at the first step of assessment. But at the present time, the care provider and client have not same concept yet, so the difference of unrsing concept between care provider and client is analyzed in this study. This study would be belived to be helpful for the advance of nursing in the future. In this study, 20 questionare from nursing objectives developed by Abdellah(basic care needs, sustenal care needs, remedial care needs and restorative care needs) are used for adult. The data of this study by the 6 point rating scale are analyzed by SAS as follows; 1. Respondent's view is that nursing is necessary in case of group(school or company) rather than private and in case of abnormal conditions rather than normal conditions. 2. Every questionares of nursing objectives are divided into 4 points of view such as basic care needs, sustenal care needs, remedial care needs and restorative care needs are examined. The evaluation by 6 point rating scale revealed that $5.08\pm0.65$ point in basic care needs $4.93\pm0.68$ point in sustenal care needs $4.91\pm0.80$ point in remedial care needs and $4.61\pm0.91$ point in restorative care needs. While basic care needs and substenal care needs that need more physical care show high points, remedial care needs and restorative care needs that need more psychological, social and spiritual care show low points. 3. It was checked whether there is any significant difference between above 4 point of views in nursing objectives and qeneral characteristics or not. As a result, there is significant difference between 4 point of view and ages, educational level, marriage, composition of children. And also there is significant difference between religion and basic care needs, remedial care needs and restorative care needs. But there is no significant difference between any point of view and sex, occupation, experience of admission and experience of family admission. As this study is based on the data gethered from a restricted area, the result can not represent the opinion of all the clients. Therefore the same kind of study should be carried out on many areas repeatedly and also it should be tried to extract objective concept. And also periodical study is needed to observe the changing process of nursing concept.
