Health care for women regularly focuses on the reproductive system to the exclusion of other health needs. The lack of research focusing on women's common health issues is a major problem to the enhanced optimal level of women's health. Health care providers have to recognize biological and social differences between men and women. This study was conducted to identify the baseline data and their correlation of health perception, health behavior, and health status of adult women for developing nursing intervention. The study was a descriptive correlational design. A convenient sampling method was used for collecting data from 103 adult women, over 18 years of age, during the period from Sep 1 to Nov 30, 2001. The study's subjects were interviewed using a structured questionnaire. The instruments for this study were the health perception scale modified by Lee(1985) based on the tool developed by Ware(1977) and Jenkins (1966), and the health behavior scale by Ko, Kumja(1987). Health status was measured by the short form Cornell Medical Index(CMI) modified by Nam, Hochang(1965). The data were analyzed SPSS PC+, by frequency, mean, t-test, ANOVA, and Pearson correlation coefficients. Also, the Duncan test was utilized for a post hoc test of ANOVA. The results of this study are as follows: 1. The mean score for health perception was 3.02(S.D=0.39) on a 5 point scale. 2. The mean score for health behavior was 3.08(S.D=0.43) on a 5 point scale. 3. The mean score for health status was 18.54 on 58 items. The mean score for physical symptoms of a subscale of health status was 11.30 on 36 items and the mean score for psychological symptoms was 7.37 on 22 items. 4. The relationship of sociodemographic variables to health perception. health behavior, and health status of women.: 1) There were significant differences in the scores of health perception by disease experience(t=-3.37, p=0.00). 2) There were significant differences in the scores of health behavior by age(F=10.52, p=0.00), height(F=4.73, p=0.01), marital status(t=-5.56, p=0.00), educational background(t=2.90, p=0.00), and drinking or non-drinking(t=2.17, p=0.03). 3) There were significant differences in the scores of health status by educational background(t=2.28, p=0.02) and disease experience(t=2.61, p=0.01). 5. Health perception showed significant positive correlation with health behavior(r=0.39, p=0.00). Health perception showed significant negative correlation with health status(r=-0.44, p=0.00), that is, the more women perceived health, the less she complained about unhealthy symptoms. Health behavior had no significant correlation with health status but showed a positive correlation with psychological symptoms of a subscale of health status(r=-0.19, p=0.05). Many of the leading causes of disease are preventable through changes in health perception and behavior. The need to increase individual awareness of relationships among health perception, health behavior, and health status and to enhance knowledge regarding the long-term effects of positive health behaviors, is an important nursing strategy for women's health promotion.

Objectives : The purpose uf this study was to evaluate the effect of Choksmni$(ST_{36})$ moxibustion in hypertensive patients who showed sudden elevation of blood pressure. Methods : Among patients admitted to Woosuk University Hospital from June to September 2004, sixty-one patients who had shown sudden elevation in systolic blood pressure over 100mmHg were chosen by random sampling and divided into a treatment group (Choksamni moxibustion group) and a control group. In the Choksamni $(ST_{36})$ moxibustion group, moxibustion was done at the point between tibial tuberosity and head of fibula where the $ST_{36}$ is known to be located. Direct moxibustion was practiced on the patients 5 times with an increase of size from a grain of rice to a bigger cluster. Male patients were chosen to practice on the left meridian and female patients were chosen to practice on the right meridian point. Changes in blood pressure after He moxibustion were checked 4 times at tine intervals of 30 minutes. In the control group, the patients took bed rest without my medical treatment. The two groups were compared in order to demonstrate whether then were any remarkable changes in depression of blood pressure. Results : There were significant decreases in the systolic and diastolic blood pressure before and after moxibustion. We found significant decreases in systolic blood pressure at 60 minutes, 90 minutes, and 120 minutes ana diastolic blood pressure at 120 minutes in the patient group compared with the control group. Conclusions : There was a statistically significant depressing effect on blood pressure elevation observed in the group with moxibustion at $ST_{36}$ versus the control group without any medical treatment.

퍼클로레이트($ClO_4^-$)는 지표수는 물론이고 토양지하수의 신규 오염물이다. $ClO_4^-$는 요오드가 갑상선에 흡수되는 것을 방해하므로 갑상선 호르몬 생성을 저하시킨다. $ClO_4^-$는 물에서 매우 용해도가 높고 안정적이라는 특징으로 인해 $ClO_4^-$를 환원하는 세균(PRB)에 의한 생분해가 자연저감의 가장 중요한 요인으로 여겨지고 있다. 산업단지 내 하천은 점 또는 비점오염원으로부터 배출된 $ClO_4^-$에 오염될 잠재성이 있다. 그래서 본 연구에서는 구미지역 산업단지 내 하천에서 물시료를 채취하여 하천미생물의 $ClO_4^-$ 분해 잠재능을 회분배양으로 조사하였다. 외부 전자공여체를 첨가하지 않고 83시간 동안 배양한 결과 모든 시료는 $ClO_4^-$ 제거효율이 0.77% 이하로 매우 낮은 것으로 나타났다. 그러나 외부 전자공여체(acetate, thiosulfate, $S^0$, 또는 $F^0$)를 첨가한 경우는 제거효율이 최고 100%로 나타났고, 첨가된 전자공여체의 종류와 시료채취지점에 따라 제거효율은 다양한 것으로 나타났다. 본 연구에서 사용한 전자공여체 중에서는 acetate를 사용했을 때 $ClO_4^-$분해효율이 가장 우수한 것으로 나타나 종속영양방식 PRB의 활성이 우세함을 알 수 있었다. 본 연구의 결과는 산업단지 내 하천 미생물에 의한 $ClO_4^-$ 자연저감에 대한 기초정보를 제공하여 원위치 생물복원처리에서 $ClO_4^-$ 생분해를 증진하기 위한 전략마련에 유용하게 사용될 것이다.

Purpose: To analyze the feasibility of three-dimensional (3D) diffusion-weighted (DW) PSIF (reversed FISP [fast imaging with steady-state free precession]) sequence in order to evaluate peripheral nerves in the elbow. Materials and Methods: Ten normal, asymptomatic volunteers were enrolled (6 men, 4 women, mean age 27.9 years). The following sequences of magnetic resonance images (MRI) of the elbow were obtained using a 3.0-T machine: 3D DW PSIF, 3D T2 SPACE (sampling perfection with application optimized contrasts using different flip angle evolution) with SPAIR (spectral adiabatic inversion recovery) and 2D T2 TSE (turbo spin echo) with modified Dixon (m-Dixon) sequence. Two observers used a 5-point grading system to analyze the image quality of the ulnar, median, and radial nerves. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of each nerve were measured. We compared 3D DW PSIF images with other sequences using the Wilcoxon-signed rank test and Friedman test. Inter-observer agreement was measured using intraclass correlation coefficient (ICC) analysis. Results: The mean 5-point scores of radial, median, and ulnar nerves in 3D DW PSIF (3.9/4.2/4.5, respectively) were higher than those in 3D T2 SPACE SPAIR (1.9/2.8/2.8) and 2D T2 TSE m-Dixon (1.7/2.8/2.9) sequences (P < 0.05). The mean SNR in 3D DW PSIF was lower than 3D T2 SPACE SPAIR, but there was no difference between 3D DW PSIF and 2D T2 TSE m-Dixon in all of the three nerves. The mean CNR in 3D DW PSIF was lower than 3D T2 SPACE SPAIR and 2D T2 TSE m-Dixon in the median and ulnar nerves, but no difference among the three sequences in the radial nerve. Conclusion: The three-dimensional DW PSIF sequence may be feasible to evaluate the peripheral nerves around the elbow in MR imaging. However, further optimization of the image quality (SNR, CNR) is required.

본 연구는 중학교 기술교육에서 기술적 문제해결 체험활동을 통해 나타나는 학생들의 변화를 탐색하는 것에 목적을 두었다. 이를 위해 연구 참여자는 경기 G시의 중학교 1학년 학생 12명을 유목적적 표집법으로 선정하였고, 자료 수집을 위해 자극 회상 질문법에 의한 심층면담, 집단토론을 실시하였다. 자료 분석 방법으로는 영역 분석, 분류분석, 성분분석 방법을 활용하였고, 연구 참여자들 간 검토 및 삼각검증을 통해 연구의 진실성을 확보하였다. 연구 결과 기술 교육에서 기술적 문제해결 체험 활동 수업은 학생들에게 '기술적 제작에 대한 부담과 흥분사이', '기술적 문제해결의 실마리와 발화점', '기술적 능력을 통한 자아의 발견'의 의미를 갖는 것으로 나타났다. 구체적으로 '기술적 제작에 대한 부담과 흥분사이'는 평소 성적이 우수한 학생들은 수행평가에 대한 심리적 부담감을 많이 느꼈지만, 일반적인 '만들기'에 대한 선(先)경험과 흥미는 체험활동에 대한 흥분감을 느끼도록 하였음을 의미한다. '기술적 문제해결의 실마리와 발화점'은 생소한 체험활동 과제를 해결하는 과정에서 모둠원들과의 관계 이해 및 형성을 중요시 하게 되고, 지속적 문제 해결력을 갖도록 함을 의미한다. '기술적 능력을 통한 자아의 발견'은 체험활동 학습을 통해 스스로 '만들어가는' 학습 경험의 중요성을 깨닫게 되고, 내면의 조작적 욕구 충족의 기회가 될 수 있음을 의미한다. 이러한 결과는 향후 기술 교육에서의 기술적 문제해결 체험활동 교육을 보다 의미 있고 체계적으로 설계하는데 필요한 기초 자료로 활용될 수 있을 것으로 기대한다.
