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

이 연구는 이학적·청각학적 정상 소견을 가진 성인들의 다중주파수 고막운동도(multi-frequency tympanogram, MFT)와 다중성분 고막운동도(multi-component tympanogram, MCT)의 특성을 알아보고자 하였다. 연구 참여자는 D대학교 재학 중인 19명(M:F=9:10, 만 19∼23세)으로 하였다. MCT는 각 성분(admittance; Y, susceptance; B, conductance; G)별 정점의 수를 확인하였고, MFT는 200 ㎐부터 2 ㎑ 순음에 대한 고막 긴장 및 이완상태에서 전도율을 통해 공명주파수와 ΔB, Δ∅를 각각 구하였다. MCT는 668 ㎐ 자극에 대해 47.4 %가 1Y1B1G를, 52.6 %가1Y3B1G를 보였고, MFT의 공명주파수는 829~1,213(1,021±192) ㎐, ΔB와 Δ∅의 평균은 각각 –0.18, -19.3으로 관 찰되었다. This study will be to confirm the characteristic of Multi-component tympanogram(MCT) and Multi-frequency tympanogram(MFT) of adults who have physical and audiological normal findings. Participants were 19 students(M:F = 9:10) who are attending D-university. MCT checked the number of peaks per each component(admittance; Y, susceptance; B, conductance; G) and MFT got the resonance frequency through the conductivity rate of tympanic membrane's tense and relaxation state, and ΔB, Δ∅ respectively. 47.4% of MCT showed 1Y1B1G about 668 ㎐ stimulus and 52.6% of that showed 1Y3B1G. Resonance frequency of MFT was 829~1,213(1,021±192) ㎐, and the average of ΔB and Δ∅ was observed -0.18, -19.3 respectively.

Background: Patients with chronic renal failure traditionally have been recognized as being at risk for perioperative bleeding diathesis. However, there has been a few reports that chronic renal failure patients showed a hypercoagulability. The purpose of this study was to assess blood coagulation profiles in patients with chronic renal failure using a thromboelastography. Methods: Thirty patients (ASA physical status, 2 and 3) with chronic renal failure (experimental group), were scheduled to get presenting for an arteriovenous fistula formation, and 30 patients with normal renal function (control group) were randomly selected. Blood sampling for a thromboelastography was performed prior to induction of anesthesia. A thromboelastography was analyzed by measuring R time, K time, maximum amplitude (MA), α degree, and TEG index. Laboratory tests including serum blood urea nitrogen, creatinine, hematologic data (hemoglobin, hematocrit, platelet count), and coagulation data (PT, PT-INR, aPTT, BT) were also measured in all patients preoperatively. Results: In the thromboelastographic indices, K time was significantly decreased and MA, α angle, and TEG index were significantly increased in patients with chronic renal failure (experimental group) compared with the control group (P < 0.05). However, there were no significant differences of PT, PT-INR, aPTT, BT between the groups. Conclusions: Thromboelastographic data demonstrates a hypercoagulable state in patients with chronic renal failure. This finding suggests that traditional concern for bleeding diathesis in patients with chronic renal failure may require reassessment. (Korean J Anesthesiol 2002; 43: 407~412)

In the course of screening for the antifungal compounds against Candida albicans, an antifungal compound (F1480) was isolated from the culture broth of Aspergillus candidus F1484. Isolation and purification of compound F1484 were performed using ethyl acetate extraction, silica gel column chromatography, ODS column chromatography, and preparative HPLC. The structure of compound F1484 was determined by the spectroscopic analyses of EI-MS, ^13C-, ^1H-NMR, DEPT, HMQC, and HMBC. This compound appeared to have a structure of antifungal agent, chloroflavonin. In addition to antifungal activities against the yeast phase of Candida species, compound F1484 showed cytotoxic effect against various human tumor cell lines.

Due to the chemical and structural diversity of organic compounds, synthesis of the value-added chemicals strongly relies on microbial production in recent years, rather than a multi-step organic synthesis. In particular, there are at least 50,000 different terpenes, biosynthetic hydrocarbons, in nature, and their wide use in food, cosmetics, and even pharmaceutical industries necessitates genetically adaptable microorganisms, such as yeasts, enabling efficient and selective production of the high-value hydrophobic terpenes. However, the hydrophobic products are significantly lipotoxic, and their mass production is inevitably limited to the storage capacity of the cells. In this study, we demonstrate yeast metabolic engineering for greatly expanding the lipotoxic chemical storage by engineering subcellular lipid droplets (LDs). Because the LD, the hub of lipid metabolism, can sequester hydrophobic compounds into their core or phospholipid monolayer, we overexpressed or deleted LD-associated genes to maximize the storage capacity of LDs in yeast. Based on our engineered yeast strain, we observed a dramatic increase in terpene production; the optimal strain succeeded in 6-fold larger production of triterpene, compared to the control strain, indicating that our LD remodeling strategy is indeed effective for improving bioproduction of value-added hydrophobic compounds.

Platelet-activating factor (PAF) acetylhydrolase, which removes the acetyl moiety at the sn-2 position, has been found in human amniotic fluid. We purified this enzyme by ammonium sulfate precipitation, and sequential use of DEAE-Sepharose CL-6B, hydroxyapatile, chelating-Sepharose, and Mono Q column chromatographies. This enzyme exhibited broad pH optima and was unaffected by EDTA. Partially purified enzyme had a molecular weight of approximately 34 kDa on SDS-PAGE. In addition, the enzyme activity was inhibited by either diisopropylfluorophosphate(DFP) or p-bromophenacylbromide (p-BPB), suggesting that this enzyme possesses active serine and histidine residues. The enzyme showed similar activity towards PAF and oxidatively modified phosphatidylcholine, but didn't hydrolyze phosphatidylcholine or phosphatidylethanolamine with a long chain fatty acyl group at sn-2 position.
