The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various Physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior. through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly' hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1.There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2.There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3.There was significant difference in self-efficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. There was positive correlation between self efficacy and self care behavior depending on the measuring period. 4.There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the, program. and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

劉正守 전주교육대학교 1995 論文集 Vol.31 No.-

We present a neural network architecture that simultaneously performs segmentation and recognition of input pattrns that self-organizes to detect input pattern locations. We present herea neural network algorithm that simultaneously sigments and recognizes in an integrated system. The resulting system simultaneously segments and recognizes seperating characters and nosiy images with high accuracy. But, this algorithm encounters difficulty if the characters are touching broken. This algorithm is able to take position-independent information as targets and self-organize the activities of the nodes in a competitive fashion to infer the position information

본 연구는 예비보육교사가 보육실습이라는 과정에서 프로젝트 접근법에 대한 관심은 어떠하며, 관심변화 여부를 사례중심으로 살펴보는 것을 목적으로 하였다. 이를 위하여 예비보육교사를 대상으로 보육실습 사전과 사후검사를 실시하였으며, 자세하고 구체적인 사실과 연구의 질적인 부분을 찾아보고자 인터뷰하였다. 그 결과, 첫째, 프로젝트에 대한 예비보육교사들의 관심은 전반적으로 무관심으로 나타났다. 둘째, 사전․사후검사 결과, 프로젝트 접근법에 대한 관심수준의 변화가 있었던 사례에서는 관심변화의 패턴도 다양하게 나타났으며, 관심변화가 크게 없었던 사례에서는 개인, 정보관심이 높게 나타났다. 이러한 결과는 프로젝트에 대한 예비보육교사의 관심수준은 보육환경, 보육과정, 실습지도 교사, 예비보육교사의 지각력, 프로젝트에 대한 사전지식이나 교육정도에 따라 다양하게 변할 수 있음을 알게 되었다. The purpose of this study is to analyze the case in which we can identify how the SoC of prospective child care teachers about the project approach changes and why these change appears during the child care practice when we assumpt that for prospective child care teachers to implement the project approach is that they participate in change during child care practice. In Case K, the SoC of the prospective child care teacher moves from Stage 0 awareness to Stage 2, Stage 3, Stage 4, and In Case M, the SoC moves from Stage 0 to Stage 1. In Case P, the SoC moves from Stage 1 to Stage 2, Stage 3, and in Case S, the SoC isn't changed. Above this, we identify the SoC of prospective child care teachers. Case K, M, and P changes SoC after child care practice, but Case S doesn't change. the reason why there is a difference is the mindset of prospective child care teachers. Anyone who wants to accomplish specific purposes can deal with diverse changes with flexibility, but others can easily have an effect on the changes. We suggest that instructor in organization for prospective child care teachers’ education need to have a class for prospective child care teachers to put theory into practice, give direct facilitation and intervention in the field to prospective child care teachers, make a learning environment for prospective child care teachers to make good use of teaching materials and instrument, develop guidebook for project approach and give support to prospective child care teachers.

Purpose : The purpose of this study was to investigate factors influencing burden in primary caregivers caring for an elderly person who has had a stroke. Method : A convenience sample of 124 primary caregivers of elderly people with a stroke admitted to an oriental medicine hospital participated in this study. Interviews were done with a standardized questionnaire including Caregiver Burden Scale (Chang, 1995). Result: Average burden score was 93.19, indicating a moderate to severe level of burden. Time-dependent burden had the highest score of the sub-domains. For general characteristics, the factors significantly influencing caregiver burden were gender and age of the elderly person, age and educational level of the caregiver, whether living together or not, and the presence of another caregiver. Multiple regression analyses demonstrated that level of ADL of the elderly person, relationship between the elderly person and the caregiver prior to the stroke, caregivers' relation to the elderly person and primary income were significant factors in explaining variance in overall burden. Conclusion : Recognition of high levels of caregiver burden and factors influencing burden will allow us to develop different nursing strategies to decrease caregiver burden in those caring for an elderly person with a stroke.

목 적 : 고포도당으로 자극한 백서 메산지움 배양세포에서 p38 mitogen activated protein kinase (MAPK)의 활성화와 p38 MAPK의 상부와 하부인자로 알려져 있는 MAPK kinase 3/6 (MKK3/6)와 c-AMP responsive element binding protein (CREB)의 활성화, 그리고 fibronectin 합성을 자극 시간에 따라 관찰하고, p38 MAPK 경로와 fibronectin 합성 사이의 연관성을 규명함으로서 당뇨병성 신증의 병태생리를 규명하고자 하였다. 방 법 : 백서 메산지움 배양세포를 정상 포도당 (5.6 mM), 고포도당 (30 mM), 또는 정상 포도당+만니톨 (24.4 mM)로 자극한 후 첫째 p38 MAPK; 둘째 p38 MAPK의 상부 인자인 MKK3/6; 셋째 p38 MAPK의 하부인자인 CREB; 넷째 MAPK phosphatase-1 (MKP-1)의 변화를 자극 시간 (3분-48시간)에 따라 Western blot을 이용하여 관찰하였으며, 다섯째 fibronectin의 변화는 RT-PCR과 ELISA를 이용하여 확인하였다. 결 과 : 고포도당으로 자극한 백서 사구체 메산지움 배양세포에서 p38 MAPK 경로가 활성화 되었다. Total p38 MAPK 단백은 변화가 없었으나, 활성화된 phospho-p38 MAPK 단백은 고포도당군에서 자극 10분 후부터 정상 포도당군에 비해 의의있게 증가되었으며 (평균 1.9배), phospho-CREB 단백 역시 고포도당군에서 자극 10분 후부터 의미있게 증가되었다 (평균 2.5배). 이에 비해 p38 MAPK의 상부인자인 phospho-MKK3/6는 고포도당군에서 자극 3분 후부터 의의있게 증가되었다 (평균 2.4배). 또한, MKP-1 단백 발현은 고포도당군에서 p38 MAPK의 활성이 증가하기 시작한 시기와 동일한 시기 (자극 10분 후)부터 증가하기 시작하였다 (평균 1.9배). Fibronectin mRNA와 세포 배양액내 fibronectin은 고포도당군에서 자극 48시간 후에 각각 1.7배와 1.5배 증가되었으며, 이러한 증가는 p38 MAPK 억제제인 SB203580 (1 μM)에 의해 각각 73%와 69% 억제되었다. 결 론 : 고포도당으로 자극한 백서 사구체 메산지움 배양세포에서 p38 MAPK 경로의 활성화를 확인하였으며, p38 MAPK 억제제가 고포도당에 의한 fibronectin의 합성 증가를 억제시키는 것으로 보아 당뇨병성 신증에서 관찰되어지는 fibronectin의 축적에 p38 MAPK 경로가 관여할 것으로 생각된다. Background : The p38 mitogen-activated protein kinase (MAPK) pathway is activated by several stress factors, potentially leading to cellular apoptosis and growth. Little is known about the pattern of p38 MAPK pathway activation in mesangial cells under high glucose conditions. We examined the activity and expression of p38 MAPK members, 1x78 MAPK, MAPK kinase 3/6 (MKK3/6), c-AMP responsive element binding protein (CREE), and MAPK phosphatase-l (MKP-1) in cultured rnesangial cells exposed to high glucose. Methods : Mesangial cells were subcultured from rat glomeruli isolated by sieving technique. After serum restriction for 48 hours rnesangial cells were exposed to 5.6 mM glucose (low glucose, LG), 5.6 mM glucose+24.4 mM mannitol (LG+M), or 30 mM glucose (high glucose, HG) for 3 minutes to 48 hours with or without SU203580. Western blot was performed to determine the activity and protein expression of p38 MAPK members. R`I-I`CR and ELISA were performed for fibronectin mRNA expression and fibronectin synthesis, respectively. Results : p38 MAPK and CREB activities were significantly increased in rnesangial cells exposed to FIG compared with LG or LG+M after 10 minutes and was sustained at higher levels to 48 hours (p<0.05), but total p38 MAPK and CREB protein expressions did not differ. MKP--1 showed a similar pattern as p 3 MAPK and CREE (p<O.O.i). MKK3/6 acitvity was significantly higher in HG cells after 3 minutes and remained at higher levels throught the study period (p<0.05). Fibronectin mRNA expression and fibronectin synthesis were significantly increased in mesangial cells exposed to HG after 48 hours (p<0.05). SB203580 (1 pM) pretreatment for 1 hour significantly reduced HG-induced fibronectin mRNA expression and fibronectin synthesis by 73% and 69%, respectively (p<0.05). Conclusion : p38 MAPK activity was increased in mesangial cells exposed to HG in parallel with increased MKK3/6 activity, resulting in CREB activation and increased fibronectin synthesis. This activated p38 MAPK may play a role in the pathogenesis of diabetic nephropathy.
