Pressure sores are a serious concerns in that respect to increasing risk of medical complications and medical costs. Prevention and care of pressure sores is an essential area of nursing practice. The nurse at ICU should be more careful of maintaining the skin integrity of patients especially than at any other place. This study was conducted to determine if the risk facotrs of pressure sores and nutritional status of the patients at risk for pressure sores is related the occurance of pressure sore. The risk group refers the patients having the below 14 scores of the braden scale. The 100 subjects were recruited from the ICU ward at an university hospital in Choongnam. The parameters for nutritional status are the blood chemistry including plasma protein, albumin, hemoglobin and the anthropometric measurements consisting of weight, BMI, LBM, the proportion of body fat, body fluid and triceps skin fold using bioimpedence analizer and caliper. The results are as follows : 1. The subjects were 55 years and stayed 8 days on average. Of the 100 subjects, males were 61%, neurologic/neurosurgical diseases were 68% and the incidence of pressure sores was 17% mainly occuring within 3days after the admission. 2. The present paralysis(or paraplegia) and edema(arm, leg, trunk) were showed more significantly the subjects with pressure sores than those without pressure sores. 3. Regarding with the nutritional status, the subjects with pressure sores had significantly lower the weight, BMI, LBM, body fluid, albumin than the ones without pressure sores. This results were supported the reports of previous studies that the decreased weight and albumin could be the important predictors of pressure sores. Thereafter we should encourage these factors to be utilized in predicting pressure sores for a comprehensive assessment. Nurse should identify patients at risk of the development of pressure sores, assess their nutritional status and dietary intake at regular intervals.

This study was designed to determine anxiety factors and levels of anxiety of foreign industrial workers. One hundred and seventy five workers were researched who were working in Guro Working Complex, Ansan City and Sungnam City Working Complex asking 60 questionnaires from Feb. 25, 1996 to April 12, 1996. The results were as follows ; 1. The 30.3% of foreign workers were from Nepal, 17.7% from Bangladesh, 10.9% from SriLanka, 14. 9% from Philippines, 1.1% from Ghana. 80% of foreign workers were male, 11.1% were single and most of them were in the age from 25 to 34. 37.1% of foreign workers had not lived in Korea less than 12 months, 58.8% graduated from college, 33.7% from high school, and more than half lived in a dormitory. 2. On the anxiety level related to subject workers' general characteristics, the anxiety level from Nepal recorded the highest point 2.70 statistically showing a significant difference(p=0.0003). On the physical anxiety level, the workers from Nepal recorded a significantly low point comparing with Jamaica, Burma, Vietnam and Nigeria(p=0.01). 3. Emotional anxiety level marked the highest on the workers living as a tenant comparing with the workers in dormitory. 4. On anxiety factors, the emotional anxiety recoded the highest, the social anxiety and the somatic anxiety. 5. On the relation between the anxiety factor, the somatic anxiety factor had a relation with emotional, environmental, and occupational factors and on the other relation between the anxiety factor and emotional factor had a relation with environmental, social, cultural factors. Moreover, the environmental factor had a relation with the cultural factor, social factor had a relation with the cultural factor, and cultural factor was related to the occupational factor.

The purposes of this research were to identify nursing interventions performed by Korean nurses and to compare the interventions performed by nurses working in the oriental medicine hospitals and with those performed by nurses working in the general hospitals. The samples consisted of 144 Korean nurses working in three hospitals, 70 nurses working in the oriental medicine hospitals and 74 nurses working in the general hospitals. The Nursing Interventions Classification (NIC) Use Questionnaire developed by the Iowa Intervention Project team was translated to Korean and verified using the method of back-translation. The questionnaire consists of 433 intervention labels and definition. Thirteen interventions were used at least daily by nurses working in the oriental medicine hospitals, while twenty-one interventions were used at least daily by nurses working in the general hospitals. The most frequently used interventions by nurses working in the oriental medicine hospitals were Documentation, Shift Report Vital Signs Monitoring, Pressure Ulcer Prevention, Positioning, Fall Prevention, Exercise Promotion, Intravenous (IV) Therapy, Pressure Ulcer care, and Bed Rest Care in that crder. For nurses working in the general hospitals the most frequent intervention was Analgesic Administration, followed by the interventions of Medication Administration : Parenteral and Intravenous Therapy (IV) Therapy, Documentation, Intravenous(IV) Insertion, Shift Report, Fall Prevention, Vital Signs Monitoring, Medication Adnninistraction : and, Fluid Monitoring, and Medication Maragement in that order. The interventions performed least often by nurses working in the oriental medicine hospitals were Hemodialysis Therapy and Bleeding Reduction : Antepartum Uterus, while the interventions performed least often by nurses working in the general hospitals were Rape Trauma Treatment and Contact Lens Care. The nurses working in the oriental medicine hospitals performed the interventions in the Physiological : Complex domain significantly more often than the nurses working in the general hospitals, while the nurses working in the general hospitals performed the intervention in the Behavior domain significantly more often than the nurses working in the oriental medicine hospitals. This study suggests that further study will be needed to developed and validate more interventions sensitive to Korean culture.

Biopolymer from alkaline-tolerant Bacillus so. was purified, and its physico-chemical and structural properties were investigated. Crude biopolymer, precipitated by acetone from culture broth was fractionated into two fractions by gel chromatography on Sephadex G-200. Among two fractions, one fraction(PS I), which an acidic biopolymer precipitated by the CPC(cetylpyridinium chloride) treatment was studied further. PS I fraction had carboxyl groups and was positive at color reaction of sugar. PS I fraction also showed UV absorbance at 190-225nm. The purified acidic biopolymer was composed of 4% glucose, 8% glucosamine and 88% glutamic acid. Sugar components of the purified acidic biopolymer seemed to be linked to PGA(polyglutamic acid) which existed in the from of ${\gamma}$-peptide bond. By the results of Smith degradation of sugar components, glucose and glucosamine was bound by 1,3 glocosidic linkage. Therefore, this biopolymer was a glycopeptide, oligosaccaride ${\gamma}$-PGA. We concluded that the equivalent weight and the molecular weight of this biopolymer were estimated as about 171 and 5x105 dalton, respectively.

본 연구에서는 토마스 영(T. Young)이 빛의 간섭 이론을 형성하는 과정에서 보인 창의적 사고과정을 분석하여 과학교육 특히 과학을 통한 창의성 교육에 대한 시사점을 도출하는 데 목적을 두었다. 이를 위해 영(Young)이 직접 집필한 빛의 간섭 이론에 대한 논문을 분석하는 문헌분석의 연구방법을 적용하였다. 연구결과는 다음과 같다. 첫째, 영은 소리와 빛의 유사성을 추론하는 과정에서 비유추론을 사용했으며, 이 과정에서 영의 예리한 관찰력을 볼 수 있다. 둘째, 영은 파장이 같은 두 물결파가 나타내는 파동의 간섭 현상으로부터 귀추하여, 같은 근원의 두 빛이 어떤 거리에서 중첩될 때 밝고 어두운 연속적 무늬를 나타낼 수 있음을 추론하고 빛의 간섭 현상을 설명하는 가설을 설정하게 된다. 그리고 실험 장치를 개발하여 이를 증명하였으며 이것은 빛이 파동임을 증명하는 결정적인 실험이 된다. 이것으로부터 전혀 다를 것 같은 소리와 빛 사이의 유사성을 영이 발견한 것도 창의적이지만 그 유사성을 좀 더 높은 수준의 '파동성'으로 추론한 것뿐만 아니라 동일한 빛이 갈라졌다가 만날 때 밝고 어두운 무늬를 보이는 현상이 두 물결파가 만나 보강과 소멸을 보이는 현상과 동일한 이론으로 설명될 수 있음을 추론하여 빛의 간섭 현상을 설명하는 가설을 추론한 것 또한 성공한 귀추의 하나로 중요한 창의성 발현에 속한다. 끝으로 영은 물결파의 간섭현상을 보이기 위해 실험 장치를 고안하였으며, 파동의 중첩을 쉽게 설명하기 위해 슬라이더 장치를 고안하였다. 또한 빛의 간섭 현상을 보이기 위한 이중 슬릿 실험 장치를 고안하였다. 이상과 같이 영의 빛의 간섭 이론을 형성하는데 활용한 비유추론과 간섭 현상을 보이기 위한 실험 장치는 과학교육에서 창의성 교육에 적절히 활용할 수 있는 교육방법과 실험설계이다.

본 연구에서는 중학교 과학교과서에서 많이 제시되는 과학 개념 모형에 대해 학생들로 하여금 단순히 읽고 지나가는 것이 아니라 주목하고 분석해 보는 시간을 갖게 하는 것이 과학 개념 학습에 어떠한 영향을 미치는지를 조사하였다. 과학 개념 모형에 좀 더 주목하고 분석해 보게 하는 방법으로 본 연구에서는 미완성 과학 개념 완성 활동과 과학 개념 모형 수정 활동을 고안하였으며, 이들 활동을 전통적 수업활동과 비교하였다. 연구 대상으로는 B광역시 소재 1개 중학교 3학년 학생 112명(3개 학급)을 표집하였다. 이렇게 표집한 3개 학급은 각각 미완성 개념 모형을 완성하는 활동, 주어진 개념 모형을 수정하는 활동, 전통적인 과학 수업 활동을 하도록 하고 그 성취도를 비교하였다. 본 연구의 결과는 첫째, 미완성 과학 개념 모형 완성활동은 전통적 과학 수업 활동에 배해 중학생들의 과학개념 학습에 효과적이라고 할 수 있다. 또한, 개념 모형 완성 활동을 통한 성취도는 학생들의 학교 성적이 높을수록 높고, 학생들의 인지 수준이 구체적 조작 단계에 있는 학생이거나 과도기에 있는 학생들이 높다. 둘째, 과학 개념 모형의 수정 활동은 전통적 과학수업 활동에 비해 중학생들의 과학 개념 학습에 효과적이라고 말하기 어렵다. 또한, 과학 개념 모형의 수정활동을 통한 성취도는 학생들의 학교 성적이 높을수록 높기는 하지만 하위 수준 학생들의 경우에는 수업 후 성취도가 높아지지 않음을 볼 때 개념 모형 수정 활동은 중학생 수준에는 적합하지 않다고 할 수 있다. 셋째, 중학교 학생들의 경우에는 미완성 과학 개념 모형의 완성 활동을 통한 수업이 과학 개념 모형 수정 활동을 통한 수업에 비해 개념 학습에 효과적이다.
