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 purpose of this study was to develop a wearable platform system that can detect and acquire a soldier’s biosignals (i.e., heart activity signal, respiration rate, etc.) in a nonrestrained, unconscious manner. These detected biosignals are transmitted to a processing device to analyze and monitor the soldier’s physical status. To achieve this, textile-based heart activity electrodes and a strain gauge sensor for the respiration signal measurement were developed, and their performances in detecting each signal were verifed. These sensors were embedded in a chest belt to design a wearable platform that can simultaneously measure heart activity and respiration signals. The sensor part of the chest belt has a dual layer structure to detect high-quality signals. Stretch fabric was used on the outer layer and a respiration sensor was attached to the belt. On the inside layer, a non-stretch fabric was used as the base fabric and a heart activity-sensing electrode, that is capable of taking measurements using a modifed lead-II heart activity signal induction method, was embroidered onto the fabric. Subjects were asked to wear the chest belt, and a biosignal processor module was attached to verify the system’s performance while simultaneously acquiring the heart activity and respiration signals. More specifcally, it was confrmed that the two signals were detected in a stable. It is expected that the biosignal-monitoring wearable platform system developed in this study will be able to efectively analyze and monitor soldiers’ biosignals.

Triboelectric properties of woolen fabrics on the clothing have been investigated in atmosperic ambient of 20℃ 75% RH. Woolen fabrics which are charged up by friction each, for other-example, over wear and under wear, give fabrics absorption, electric shock and other problems of health in winter especially. So authors have studied on triboelectric properties of the woolen fabrics by friction of the fabrics, nylon, acetate, polyester, exlan, viscose and cotton, and have measured surface resistivity of the samples. The results were as follows. Charge quantity on woolen fabrics of Plain weave, Twill weave and Satin weave were less than that of knitting fabrics. Cotton and viscose were suitable to under-wear or lining of woolen fabrics, and nylon was more suitable than acetate, polyester, exlan in this experiment. Surface resistivity-and charge quantity of warp direction were less than those of weft and bias directions on nylon, and the surface resistivity and charge quantity of course direction were less than those of wale, bias direction on woolen jersey.

Fresh-cut 채소 제품이 소비자에 의해 선택되어 소비되려면 이의 친환경적 원료생산과 가공, 포장, 서빙에 이르는 전 과정에서 체계적인 품질관리가 이루어져야 하며 갈변제어, 연화제어 및 미생물적 제어 등 관련 기술의 연구개발이 요구된다. 본 연구에서는 시중 유통 · 판매되고 있는 fresh-cut 채소제품의 품질을 비교평가하기 위해 현재 유통되고 있는 9개사 제품을 선정하였으며, 관능검사를 포함하여 vitamin C, 무기질, 중금속 함량, 잔류농약 및 미생물오염 정도를 조사하였다. 관능평가에서는 갈변 등 품질변화로 인해 전반적인 기호도가 그다지 높지 않았다. 채소류에서 중요 영양성분인 vitamin C 함량은 9개사 모든 제품의 주재료인 양상추에서 거의 검출되지 않았고 다른 채소류의 vatimin C 함량 역시 식품성분표보다 소량이었다. 무기질 함량 역시 극히 소량이었는데, 이는 박피, 절단 등의 최소 가공 공정을 거치면서 파괴되기 쉬운 vitamin C와 무기질이 대부분 손실되었기 때문으로 사료된다. 안전성측면에서 평가한 잔류 중금속 함량의 경우 몇 개의 제품에서 구리와 납이 소량 검출되었으며 잔류농약은 검출되지 않았다. Most fresh-cut agri-food products are less stable than the unprocessed materials from which they are made. The objective of this study was the development of a quality control system for fresh-cut agri-food products. In this study, the vitamin C, mineral, residual heavy metal contents and pesticides of various fresh-cut agri-food products were analysed. Through the sensory evaluation, the reason for the lower than expected overall acceptability in most products is that cut products are likely to cause browning and easily lose their freshness. Therefore, the postharvest technology that can maintain the quality, freshness and appearance must be supplied. Vitamin C contents did not exist in all salad products of the selected 9 companies, although vitamin C and mineral contents that are main nutrients that can be supplied mainly in salads. The results showed that vitamin C and mineral contents were very small and extremely small in other vegetables compared with the standard of a food ingredient, It is possible that vitamin C and most minerals are easily destroyed were lost through the minimal process like peeling and cutting. In safety side, the remaining heavy metal contents of fresh-cut agri-food were investigated and the results showed that copper and lead existed in some products because cadmium in agricultural produce is only controlled by the minimum standard of heavy metal contents in Korea. No residual pesticides were detected in all products.

동북아시아에 분포하는 땅비싸리와 좀땅비싸리의 분류학적 한계를 규명하기 위하여 형태적 변이와 염색체수가 조사되었다. 땅비싸리의 이명으로 취급되어 왔던 좀땅비싸리는 소엽의 모용, 꽃의 크기, 화분형태, 지리적 분포 등에 있어 땅비싸리와 뚜렷한 차이를 보였으며, 또한 염색체수가 4배체(2n=32)로 나타나, 2배체(2n=16)인 땅비싸리와 차이를 보였다. 땅비싸리와 좀땅비싸리 11 집단을 대상으로 19개의 외부형태 형질에 대한 주성분분석을 실시한 결과 두 종은 제1주성분에 의해 뚜렷이 나누어 졌는데, 전체분산에 대한 제1주성분의 기여율은 63.2%이었으며, 제1주성분은 소엽 표면의 털과 화서의 길이 등과 높은 상관성을 보였다. 이러한 결과로부터 좀땅비싸리는 땅비싸리와는 구별되어 독립된 종으로 처리되었다. 한편 큰땅비싸리는 땅비싸리의 변이의 한 형태로 판단되므로 땅비싸리의 이명으로 처리되었다. 각 종의 지리적 분포에 대한 분류학적 의의가 염색체수 변이 등과 비교논의 되었다. The morphological analysis and cytological study of Indigofera kirilowii Maxim. and Indigofera korean Ohwi were undertaken to assess the numbers and ranks of taxa that usefully could be recognized. I, koreana, previously recognized as I. kirilowiii, was separated from I. kirilowii in hairiness on leaflets, flower size, pollen exine sculptures, geographical distribution and chromasome number. Chromosome count of 2n=32 (tetraploidy) from I. koreana was obtained for the first time. The results of principal components analysis (PCA) on a matrix of 11 populations of Korea by 19 morphological characters indicated that two species could be recognized by the first principal component, contribution of which for the total variance is 63.2%. Our results supported that I. koreana could be clearly distinguished from I. kirilowii. Since the quantitative differences between the two varieties, I. kirilowii var. coreana and var. Kirilowii, were smaller, a nomenclatural synonymy was developed for them, ie, var. kirilowii.

초임계 유체 추출 공정을 이용하여 참깨에서 hydrocarbon류를 검출하여 참깨의 방사선 조사 여부 검지 전처리 기술에 활용하고자 하였다. 참깨를 2 kGy의 감마선을 조사하여 hexane으로 지방을 추출한 용매 추출과 초임계 유체 추출을 이용하여 추출한 지방을 Florisil coulumn으로 분리한 후 hydrocarbon 류를 GC-MS로 분석하였다. 용매 추출에서와 같이 초임계 유체 추출 공정을 이용하여 검출된 hydrocarbon 류은 동일하게 검지되었으며 그 marker 로써 활용 가능한 hydrocarbon 류인 13:3, 17:2, 16:2, 17:1은 비조사 참깨에서는 검출되지 않아TEk. 보조 용매르 사용한 초임계 추출 공정에서 각 보조용매에서 추출된 지방량은 용매 추출보다 많았으며 보조용매를 사용하여 검출된 hydrocarbon 류의 검출량은 methanol을 제외하고 전반적으로 많이 검출되었다. 특히 acetone의 경우 marker로 사용가능한 hydrocarbon류는 용매 추출에서보다 3~4배 정도, CO₂만을 사용함 초임계 유체 추출 공정에서 보다 거의 2배의 검출 특성을 보여주었다. 이러한 결과는 초임계 유체 추출 공정이 방사선 조사 여부 검지 기술에 있어서 기존의 용매 추출에 비해 지방 추출시 용매 소모량의 감소, hydrocarbon 류의 검출량 증가 등의 이유로 hydrocarbon 류의 검지 기술에 있어 전처리 기술로 활용 가능하리라 사료된다. Radiation-induced hydrocarbons from the irradiated sesame were investigated in this study to compare the chemical properties of irradiated and non-irradiated foodstuff. The detective volatile hydrocarbons for the irradiated sesame were (C14:0), 1-tetradence (C14:1), n-pentadecane (C15:0), n-hexadecane (C16:0), 1-hexadecane (C16:1), n-heptadecane (C17:0), 8-heptadecene (C17:0), 1,7-hexadecadiene (C16:2) 1,7,10-hexadecadiene (C16:3) 6,9-heptadecadiene (C17:2). The characteristic of extracts was also investigated at the change of pressure and temperature. And then it was found that the increase of the pressure and the decrease of the temperature in supercritical fluid extraction have made possible much more rapid extraction of volatile hydrocarbons. The amounts of volatile hydrocabons for irradiated and non-irradiated foodstuff were definitely differentiate. It could be concluded that the supercritical fluid extraction was possible for detective extraction method irradiated foods.

The measuring system controlled by microcomputer was constructed in order to measure the three dimensional flow field behind an axial flow compressor rotor. Detailed measurements were made of the flow field behind an axial flow rotating blade row using this system and a 45°single slanted hot wire. The interaction of the wake with the annulus wall boundary layer, the secondary flow and the tip leakage flow results in slower decay and larger width of the wake. By the mixing of the wake with the strong secondary flow at the corner between the hub wall and the suction side, the wake near the hub wall has the largest width and the largest axial velocity defect. The reduction of the mass flow rate entails separation, stall and larger tangential velocity. In particular, as leakage flow become strong, it absorbs the wake and affects the flow at the full passage near the casing wall.
