As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

Objective : For the purpose of preparing the fundamental data and preventing the health impairment due yo heavy metals in hair cleaner. Methods and Material : The author determined the concentration of heavy metals(Fb, fn, Cr, Ni and Cu) in hair cleaner with flameless atomic absorption spectrophotometer. Results : The results were as follows : 1. The mean concentration of heavy metals in total hair cleaner were 0.046㎍/g for Pt, 0.O67㎍/g for Mn, 0.069㎍/g for Cr, 0.046㎍/g for Ni, and 0.022㎍/g for Cu, respectively. 2. There was not statistically significant difference to mean concentrations of each heavy metal in hair cleaner by producing nation. 3. The highest mean concentration of each heavy metal in hair cleaner by type of use were 0.140㎍/g for Mn in sensitive hair cleaner(p<0.05), 0.053㎍/g for Cu in others products(p<0.01). 4. The mean concentration of heavy metals in hair cleaner by type of hair cleaner were high at 0.O54㎍/g for Pb in shampoo products(p<0.O5), 0.120㎍/g for Cr and 0.06㎍/g for Cu in combination products(p<0.01). 5. The mean concentration of heavy metals in hair cleaner by acidity were high at 0.056㎍/g for Pb, 0.124㎍/g for Cr, and 0.032㎍/g for Cu in alkali products (p<0.05). 6. Correlation coefficient of heavy metal concentration in hair cleaner were 0.175 for Pb and Cr, 0.165 for Pb and Mn, 0.824 for Cr, and Mn, 0.189 for Cr, and Ni, 0.406 for Cr, and Cu, 0.197 for Mn and Ni, and 0.375 for Mn and Cu(p<0.05). 7. Exposure amount of heavy metals per when we used lOg of hair cleaner (onetime using amount) were 0.46㎍ for Pb, 0.67㎍ for Mn, 0.69㎍ for Cr, 0.46㎍ for Ni, and 0.22㎍ for Cu, respectively. Conclusion : As above results, there was very low level concentration of heavy metal in hair cleaner but we are using the hair cleaner everyday, therefore we can exposed to heavy metals as cronic exposure so the author suggest to prepare the program of preventing the health impairment due to heavy metals.

The expression of pro-apoptotic molecules, p53 and Bax, in the spinal cord of rats with experimental autoimmune encephalomyelitis (EAE) was examined. Apoptosis was confirmed by the terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling (TUNEL) method. TUSEL (+) apoptotic cells were mainly either ED1 (+) macrophages or T-cells in the parenchyma of E N . Western blot analysis showed that both p53 and Bax expression significantly ( p < 0.01) increased in the spinal cords of EAE rats at the peak stage, and thereafter declined. An immunohistochemical study showed that inflammatory cells (notably T cells) in the parenchyma express p53 and Bax, while brain cells, includng neurons and glia, were devoid of these nuclear staining of these molecules. The nuclear expression of p53 largely matches apoptotic cells in the parenchyma of EAE. These finchngs suggest that pro-apoptotic molecules, p53 and Bax, may play an important role in eliminating T cells in the parenchyma in EAE.

Whipping and emulsifying properties of sesame proteins isolated from raw and roasted seed were investigated as a funciton of pH, NaCl and protein concentration. Solubility of the protein isolate showed minimal at pH 4.0. Heat processing of sesame lowered nitrogen solubility and diminished whipping and emulsifying properties of sesame protein isolate slightly. Whipping and emulsifying properties were minimized at pH 4.0 and increased with increasing concentration of protein isolate. Whipping properties were minimized at a 0.01M concentration of NaCl and emulsifying properties were decreased by increasing concentration of NaCl.

문명준,김희정,이서봉,이명훈 釜山工業大學校 1995 論文集 Vol.37 No.-

Ionic conductivities of PMMA-based polymer blends plasticized with poly (ethylene glycol) methyl ether(PEGMe) complexed with LiCLO4 have been investigated for applications in lithium battery. These solid polymer electrolytes are studied at room temperature using impedance analysis technique and FT-IR. Maximum ionic conductivity at room temperature was measured to be 5.9×10-5 S/cm in the free standing film state for PMMA concentratin of 17% w/w. The ionic conductivity decreases at higher PMMA concentration of 30% w/w, since the nonconducting area according to the phase separation of PMMA increases. The phase separation of PMMA in polymer electrolytes was shown by the absorbance variation of the carbonyl peak of PMMA.

김치는 배추를 주재료로 하여 마늘, 고추, 생강 등의 양념류를 포함하는 여러 재료들로 만들어지며 이들 재료 중에는 항산화효과를 가진 것으로 알려진 성분들이 많이 함유되어 있어 김치도 항산화효과를 나타낼 것으로 여겨진다. In vitro 실험계 및 세포 모델계에서 김치 재료 및 김치의 항산화효과는 확인된바 있으나 In vivo 시스템에서의 김치의 항산화효과에 관한 자료는 부족하다. 따라서 본 실험에서는 김치 섭취의 생체 내 항산화효과를 규명하기 위하여 흰쥐에게 동결건조한 김치 3, 5, 10% 첨가 식이를 6주간 섭취시키면서 간조직의 산화와 항산화효소계의 활성을 측정하였다. 간의 MDA 함량은 대조군에 비해 김치 투여군에서 낮았고 특히 5% 김치섭취군에서 현저히 낮은 값을 나타내었다. 단백질 산화를 나타내는 카르보닐 함량도 대조군에 비해 김치섭취군에서 낮아 생체 내에서 김치식이가 과산화물 생성 억제효과를 나타내었다. 항산화 효소계의 활성을 측정한 결과 SOD 활성은 대조군에 비해 김치섭취군에서 현저하게 높았고 김치첨가 함량이 증가할수록 SOD 활성이 유의적으로 높아져 10% 김치섭취군에서는 대조군에 비해 70% 이상 높은 활성을 나타내었다. Catalase 활성은 각 군에서 유의적인 차이가 나타나지 않았으나 GSH-px의 활성은 김치 섭취가 높을수록 상대적으로 높은 증가율을 나타내어 SOD 활성과 동일한 경향을 나타내었다. 따라서 김치식이는 생체 내에서 치질 및 단백질 과산화를 현저하게 억제하였고 항산화효소계인 SOD와 GSH-px의 활성을 농도의존적으로 증진시켜 김치식이가 체내의 산화적 스트레스를 효과적으로 억제하는데 기여함을 알 수 있었다. Kimchi is a Kruean traditional fermented food containing various ingredients such as Chinese cabbage, garlic, ginger, red pepper and fish sauce. Some of their components were known as its antioxidative activities and antioxidative effects of kimchi have been studied using in vitro and cell model system. To investigate the antioxidative effect of dietary kimchi, 4 groups of male S.D. rats (n=36) were fed 0, 3%, 5%, and 10% freeze-dried kimchi for 6 weeks and hepatic lipid peroxidation, protein oxidation and the activities of antioxidative enzymes were measured. Hepatic MDA content fed kimchi diet was lower than control diet. Protein carbonyl values were decreased in kimchi diet group, but not significant. SOD activities were significantly increased in kimchi added groups at dose-dependent manner. At 10% kimchi added group, SOD activity increased by 70% compared with control diet group. Catalase activities were not different between experimental groups and control group, whereas GSH-px activities were significantly increased in kimchi added group. As a result kimchi diet inhibited lipid and protein oxidation and induced antioxidative enzymes, SOD and GSH-px in rat hepatic tissue. It suggests that dietary kimchi is expected to prevent the oxidative stress in animal and human.

Study Design : Spine fusion with fixation procedure is associated with substantial operative blood loss, which frequently necessitates transfusion. The authors evaluated the safety and efficacy of intraoperative autotransfusion using Cell Saver during spinal surgery. Summary of Literature Review : It has been reported that the contraindications to the use of intraoperative autologous transfusion are malignancy, infection, and gross wound contamination. Objectives : The purpose of this study was to evaluate the safety and efficacy of intraoperative autotransfusion using Cell Saver during spine surgery. Material and Methods : We retrospectively reviewed 62 patients who had operation for lumbosacral spinal stenosis and hypotensive anesthesia. Among them, Group Ⅰwhich received autotrans fusion using Cell Savers included 26 patients with fusion of 2 segments, and Group Ⅱ as control group included 13 patients. Group Ⅲ which received autotransfusion using Cell Savers included 17 patients with function of 3 segments, and Group Ⅳ as control group included 6 patients. We analyzed the amount of intraoperative blood salvage using a Cell Saver, the amount of total homologous transfusion amount, intraoperative blood loss, the amount of postoperative drainage amount and perioperative changes of hemoglobin, hematocrit and platelet count. Results : There was no statistical significance between Cell-Saver group and control group in amount of total homologous transfusion and intraoperative(except in 2 segment of fusion using cell saver: 86.5% increased) & postoperative blood loss(p>0.05). The circulatory balance(amount of intraoperative blood salvage using a Cell Saver plus amount of total homologous transfusion minus amount of total blood loss) was statistical significance between Cell-Saver group and Control group. The Cell-Saver group had positive balance and Control group had negative balance. There were no statistical differance in the evolusion of hemoglobin, hematoocrit and platelet count between Cell-Saver group and Control group(p>0.05). There was no transfusion reaction and thromboembolic disease in all group. Conclusion : In retrospective study, Cell Savers was safe and immediate availability in orthopedic surgery such as spinal surgery. It was effective methods for storing a sufficient volume of blood for spine surgery without affecting the patient's postoperative hemodynamic ststes, too. It was possible to operation without intraoperative homologous blood transfusion in 2 or 3 segment fusion. We may need further study.

이명희,문수재,이민준,김정현 培材大學校 1997 培材論叢 Vol.2 No.-

본 연구에서는 현재까지 진행되어 왔던 국민 영양 조사 보고를 종합하여 한국인의 식생활 행태 변화에 대한 결과를 종적, 횡적으로 분석해 봄으로써 한국인의 영양문제를 파악해 보고자 하였으며, 여기에서 얻어진 결과를 요약하면 다음과 같다. 우리나라 국민 1인 1일당 에너지 섭취는 70년대까지는 증가하다가 그후 서서히 감소하는 경향이었으며 당질 섭취량은 감소하는 반면 지방 섭취량은 80년대 이전부터 조금씩 증가하기 시작하여 80년대 후반기에 이르러 그 변화가 더욱 뚜렷하였다. 곡류로 부터 얻는 열량의 비는 70년대에 82.1%에서 90년대에는 65.8%로 당질 위주의 식사에서 탈피하였다. 단백질 섭취량의 연차적 변화는 동물성 급원에서 얻는 비율이 증가하여 질적 향상을 나타냈다. 무기질중 칼슘의 섭취량은 계속 증가는 하고 있으나 권장량 수준에 미달되고 있으며, 철분의 경우는 섭취량이 꾸준히 증가하여 80년대 전반기에 이미 권장량 이상을 섭취하는 것으로 나타났다. 비타민 A는 변동의 폭이 많아 일관된 변화 양상을 볼 수 없었으며 티아민, 나이아신과 비타민 C는 권장량 이상을 섭취하고 있는 반면 리보플라빈은 연차적으로 우유 섭취의 증가와 함께 증가하여 권장량에 근접하는 섭취 양상을 나타내었다. For the last a few decades, Korea has experienced rapid economic growth, and the lifestyle of Koreans has become more westernized. Specially eating habit and food availability have changed so quickly. The main purpose of this study is to estimate the annual trend of food and nutrient intake, to evaluate the relationship between dietary pattern and the structure of disease and to define the groups that have the risk of nutritional problems. Until mid 1970s total calorie intake was provided by 75% from carbohydrate and less than 10% from fat. While total calorie intake was decreased since 1980, the composition of calorie sources has changed; calorie from fat and protein has increased and that of carbohydrate has decreased. The dietary pattern of the Korean population has rapidly changed with high intake of meat, fish and milk and low intake of cereals. With the change in dietary pattern, it could have been expected to change the major causes of death and morbidity rate.
