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

The radial error motion of a machine tool cutter/spindle system is critical to the dimensional accuracy of the parts to be machined. This paper presents an investigation into spindle run-out effects on cutting mark and surface roughness. We experimented the effects of spindle run-out on surface roughness in flat-end milling by cutting AL 7075 workpiece in various cutting conditions. In order to analyze the effects of run-out on the surface roughness, the spindle's radial error motions was measured by mounting a sphere target onto the spindle as a reference. From the experimental results, it was found that spindle run-out makes a directive effects on surface roughness in flat-end milling.

Trichoderma koningii의 영양요구성 돌연변이주인 CUT 121로부터 얻은 원형질체를 야생형인 ATCC 26113의 핵과 혼합하여 PEG 용액을 처리한 결과, 독립영양형의 형질전화체가 30% 이상의 빈도로 생성되었다. 이 독립영양형 군체로부터 얻은 분리체 중의 하나는 xylanase의 활성이 야생형보다 3배 가량 증진되었으며, 다른 세포외 다당류 분해효소능도 야생형과 유사한 수준을 나타내었다. 분리체의 DNA 함량, 인위적인 분리양상 및 동위효소 양상 등을 조사 분석한 결과, 독립영양형의 형질전환체는 실험에 사용된 두 핵간의 유전물질교환에 의하여 생성된 형질전환체로 판명되었다. 이상의 결과로부터 Trichoderma속 균류의 균주개량법으로, 핵전이법이 통상의 원형질체 융합법보다 효율적인 것으로 판명되었다. When protoplasts from auxotrophic mutant of Trichoderma koningii CUT121(Lys^-, Met^-) were mixed with isolated nuclei of wild type T. koningii ATCC 26113 and treated with PEG solution, protrophic colonies were produced with frequency of more than 30 percent. One of segregants from prototrophic colonies showed increased xylanase activity and other polysaccharide-hydrolyzing activities comparable to those of wild type strain. Through measurement of DNA contents, induced segregation, and analysis of isozyme patterns, it was revealed that the prototrophic colonies were transformants resulted from exchange of genetic materials between the two kinds of nuclei used. These results suggest that nuclei transfer technique is more efficient than conventional protoplast fusion technique for strain improvement of Trichoderma species.

Triton Ⅹ-100이 Trichoderma koningii의 성장 및 형태에 미치는 영향을 조사하기 위하여, Triton Ⅹ-100 첨가 여부에 따른 각 종 성장계수의 변화를 조사하여 보았다. 액체 배양시 Triton Ⅹ-100의 첨가에도 불구하고, specific growth rate과 doubling time은 변화가 없었으나, Triton Ⅹ-100을 첨가한 경우, 군체의 방사상 성장률이 감소하였다. 이러한 현상은 Triton Ⅹ-100에 의하여 균사의 분지 형성이 촉진되고, 격막형성이 촉진되어 격막 간의 간격이 짧아져 나타나는 것으로 확인되었다. We investigated the effect of Triton Ⅹ-100 on the growth and morphology of Trichoderma koningii by comparing various parameters representing the growth of mold in the presence or absence of Triton Ⅹ-100. The specific growth rate and doubling time of T. koningii were not affected by the addition of 0.05% Triton Ⅹ-100 into solid medium also resulted in decrease in the colony radial growth rate and this response was correlated with the formation of mycelia which showed increase in branching and septation in the presence of Triton Ⅹ-100.

우지가 5% 첨가되어 있는 일반적인 비육후기사료를 급여한 돈육(C), 우지 함량 중 2%를 들깨유로 대체 급여한 돈육(T1), 들깨유 2%에 비타민 E를 250ppm 첨가한 돈육(T2), 오징어유 2%를 대체 급여하 돈육(T3), 오징어유 2%에 비타민 E를 첨가 급여한 돈육(T4), CLA를 2% 대체 급여한 돈육(T5)의 육질특성을 조사한 결과는 다음과 같다. 지방산 조성에 있어서 오일간에는 T5가 다른 세 처리구들(C, T1, T3)에 비하여 SFA와 EFA는 높은 반면 UFA, MUFA, UFA/SFA MUFA/SFA는 낮았다. 총아미노산 함량은 오일간에는 T3가 다른 세 처리구들 (C, T1, T5)보다 높았으며, 동일한 오일에서는 비타민 첨가에 따라 높게 나타났다. TBARS의 경우 오일간에는 C와 T1에 비하여 T3와 T5가 높았고, VBN은 C<T1<T3<T5 순이었으며, 총세균수, 유산균수 및 대장균군의 경우 오일간에는 차이가 없었다. 신선육의 관능평가에서 전체적인 기호도는 C와 T1에 비하여 T3와 T5가 낮게 나타났으며, 가열육의 관능평가에서 경도는 T3가 다른 세 처리구들(C, T1, T5)에 비하여 낮아 전체적인 기호도는 높았다. TBARS, VBN, 총세균수, 유산균수, 대장균군, 신선육 및 가열육의 관능평가에서 동일한 오일에서 비타민 첨가에 따른 차이는 없었다. 이상과 같은 결과를 요약해 볼 때 우지 대신 들깨유와 오징어유를 첨가 급여시에 육질에는 뚜렷한 차이가 없었으나 비타민 첨가급여로 아미노산 함량이 증가되는 등 육질개선에는 다소 영향을 미치는 것으로 나타났다. Subjective pork quality was determined on the six groups of the following treatments. Meat samples were obtained from pigs which had been fed with finishing pig diets containing 5% beef tallow(C), 3% beef tallow and 2% perillar seed oil(T1), 250ppm vitamin E(α-tocopheryl acetate) in T1(T2), 3% beef tallow and 2% squid viscera oil(T3), 250ppm vitamin E in T3(T4), 3% beef tallow and 2% CLA(Conjugated linoleic acid, T5). In the fatty acid composition, SFA(Saturated fatty acid) and EFA(Essential fatty acid) were higher in T5 than in the rest of three treatments such as C, T1, T3 groups, while UFA(Unsaturated fatty acid), MUFA(Monounsaturated fatty acid), UFA/SFA, MUFA/SFA were low. The total content of amino acid in the T3 were higher those for the rest of rest of C, T1, T5 the content for vitamin added treatment(T2, T4) groups higher than non treated one. T3 and T5 showed higher TBARS(Thiobarbituric acid reactive substance) values than the C and T1 groups VBN(Volatile basic nitrogen) values were higher in the order of T5>T3>T1>C. There was no difference in total plate counts, number of lactic acid bacteria and number of E. coli. In sensory property, the C and T1 showed a higher acceptance than the T3 and T5. In cooked meats, the T3 showed a lower hardness than that of control(C), T1 and, with a higher acceptance. In TBARS, VBN, total counts, lactic counts, and E. coli counts sensory test of cooked meat and raw meat, there was no significant difference between vitamin supplement groups within each oil treatment.

비육후기 돼지 사료에 첨가되는 우지 함량 중 2%를 들깨유로 대체 급여한 돈육(T1), T1처리구에 비타민 E 250ppm 첨가 급여한 돈육(T2), 우지함량 중 2%를 오징어유로 대체 급여한 돈육(T3), T3에 비타민 E 250ppm 첨가 급여한 돈육 (T4)을 1±1℃에서 28일간 저장하면서 육질특성을 조사한 결과는 다음과 같다. TBARS, VBN, 총세균, 유산균, 대장균군은 저장기간에 따라 증가하였으며, 저장 28일째 총세균수는 10^7, 유산균수는 10^6, 대장균군은 10^4CFU/㎠ 수준이었다. 처리구간에 TBARS와 VBN은 들깨유를 급여한 처리구들(T1, T2)보다 낮았다. VBN에서는 비타민 첨가구들(T2, T4)이 첨가하지 않은 구들(T1, T3)보다 높게 나타났다. 신선육의 전단가는 T1구와 T3구는 저장기간에 따라 증가하였고, T2구와 T4구에서는 14일까지 증가한 이후 감소하였다. 가열육의 조직감에서 경도, 부착성, 응집성, 점착성 및 파쇄성은 14일까지 증가한 이후 감소하였다. 처리간에는 저장 28일째 비타민을 첨가한 구들(T2, T4)이 첨가하지 않은 구들(T1, T3)보다는 경도(hardness), 부착성(adhesiveness), 응집성(cohesiveness), 탄력성(springiness), 점착성(gumminess) 및 파쇄성(brittleness)에서 낮게 나타났다. 신선육의 관능 평가 결과 저장기간에 따라 지방색과 드립에서 낮은 점수를 얻어 전체적 기호도가 낮아졌으며, 처리간에는 육색, 상강도에서 T1, T2보다 T3, T4가 높게 나타났다. The equality of pork meat was determined as following treatments. The meat samples were obtained from how many which had been fed finishing pig diets containing 2% perilla seed oil in beef tallow(T1), 250ppm vitamin E in T1(T2), 2% squid oil substituted of beef tallow(T3) and 250ppm vitamin E in T3(T4). All of them was stored at 1±1℃ for 28 days until further evaluation for characteristics of the pork quality. The values of TBARS, VBN, total counts, lactic counts, E. coli counts were increased during the storage, and 10^7 of total counts, 10^6 of lactic counts. 10^4 E. coli counts were shown on the day 28. The treatments with perillar seed oil(T1, T2) showed lower TBARS and VBN than the treatments with squid oil did(T3, T4). Especially, vitamin fed pork meats showed higher VBN value than pork meat without vitamin feeding. In raw meat, the shear force of T1 and T3 fed pork meat increased during storage days while that of T2 and T4 fed one increased up to the day 14 then decreased. In cooked meat, hardness, adhesiveness, gumminess, and brittleness increased by th 14th day after storage then decrease. Also, the vitamin fed pork meats(T2, T4) showed less hardness, adhesiveness, cohesiveness, springiness, gumminess, and brittleness than vitamin non treated ones did(T1, T3). In sensory tests of the raw meat, the acceptance decreased due to low score of lipid color and drip loss. However, T3, T4 showed higher color and marbling score than T1, T2 did.
