배추를 다듬기 하는데 발생한 폐기량은 7.5∼14% (w/w)이었고 10±2℃에서 30일간 방치한 경우 약 17∼25% 발생하였다. 간절임 배추의 pH값은 저장온도가 낮을수록, 염도가 높을수록 높았으나 calcium chloride 첨가가 절임배추의 pH값의 변화에는 영향을 주지 않았다. 유리당의 함량변화는 최소 약 4% 수준에서 산의 함량과는 반비례적으로 변화하여 저장 90일에는 소금농도가 낮고 저장온도가 높은 경우 적게 감소되었다. 균수변화에서 세균과 효모는 전 기간을 통해 증가한 반면, 곰팡이는 감소하였다. 한편 산의 첨가와 CaCl? 첨가시 소금으로만 절인 경우보다 세균과 효모는 낮은 속도로 증가했다. 저장중 경도는 온도가 낮고 염도가 높으며 젖산을 첨가한 경우 다소 높게 유지됐고, CaCl? 첨가의 경우 잎과 줄기에서 월등히 높았다. 휘발산과 불휘발산의 함량변화에서 온도가 낮고 염도가 높은경우 불휘발산의 함량이 낮았는데 특히 젖산 첨가시 불휘발산의 증가를 억제하는 것으로 나타났다. flavor score 는 저온과 고염도 젖산첨가시 유리하였다. This study was to investigate the effects of storage temperature, lactic acid and calcium chloride addition about the pH values, sugar content, firmness, volatile and nonvolatile acidity, microbial counts and flavor of the salted chinese cabbages during storage (90 days), and trim loss of chinese cabbages during the trimming of raw and storaged (30 days) chinese cabbages. The waste rate was in the course of trimming of raw chinese, cabbages was 7.5-14(w/w). The proportion of trim loss was highly correlated to sunshine duration, temperature, humidity and handling for the storage. Free sugar was decreased fast and much in the case of high temperature and low level sodium chloride in comp rison of low temperature and high sodium chloride, but ?? and lactic acid did not affect its changes. Time to reach the lowest pH values were fast in the case of high temperature and low salt content. Lactic acid affected inital pH value (4.38-4.57) and constant pH value in each case was increased at low salt content, at high temperature, and then the pH values were slowly increased when volatile acidity was increased. Firmness was high in the case of addition of lactic acid and calcium chloride, low temperature, high sodium chloride concentration. Especially, calcium chloride addition remarkably showed high firmness. Flavor score was high in the case of low storage temperature, high yeast counts were slowly increased in spite of low temperature and high salt content, but mold counts were slightly increased during all period Lactic acid, low temperature and high sodium chloride were effective to inhibit the growth of microorganisms. Volatile and nonvolatile acidity was increased during all storage period ; however, lactic acid and low temperature storage inhibited their increase. To conclude, quality of salted chinese cabbages was effective at low temperature storage, lactic acid and calcium chloride addition, and high salt concentration.

Bupivacaine is an amide-type local anesthetic widely used for regional anesthesia. Ropivacaine is developed as a less cardiotoxic alternatives to bupivacaine. In the present study, we have analyzed the effects of bupivacaine and ropivacaine on HERG currents expressed in Xenopus oocytes. Bupivacaine and ropivacaine(3∼1,000μM) blocked HERG currents in a concentration dependent manner. EC_(50) was 26.1±3.1μM(n_(R) 0.65±0.04) and 43.5±7.9μM(n_(H) 0.99±0.13) in bupivacaine and ropivacaine, respectively. Bupivacaine and ropivacaine did not affect the activation and deactivation kinetics of HERG channels. However, the drugs decreased the slope conductance measured from fully activated current-voltage relationship curves. These results suggest that bupivacaine and ropivacaine have a similarinhibitory effect on HERG channels, which could be a possible cellular mechanism of LQT or ventricular arrythmia by the drugs.

Purpose: This study was aimed to identify the influencing factors on the quality of life among breast cancer survivors. Methods: The subjects were 159 female patients who visited out-patient department (OPD) after the mass removal surgery for breast cancer and had completed adjuvant treatments such as chemotherapy radiation therapy at a university hospital and a general hospital. Data collection was conducted using the Ferrell QOL scale the Mishel uncertainty scale the Fitts & Osgoods body image scale revised by Jeon & Kim. the Rosenberg self-esteem scale and the Kang family support scale. Results: The level of QOL in the participants was in the middle. There were a significant correlation between QOL uncertainty self-esteem and family support. There were significant differences in QOL with the perceived health condition and the best support person. In a regression analysis the most powerful predictor of QOL was body image (21.7%). Altogether uncertainty and perceived health condition explained 28.6% of the variance of QOL of the participants. Conclusion: Body image uncertainty and perceived health condition were important predictors of QOL. These results demonstrated the need for developing interventions to improve QOL of breast cancer survivors.

The purpose of this study were to develop Knowledge Management System for the nurse and to identify its effectiveness. The program was developed in development of the contents and programing. And the system was operated to 85 nurse for three weeks. Data collection were performed during the period of May 1, 2005 to December 30, 2005. The data was collected from 85 nurses using questionnaires. In order to ascertain the validity of clinical application of the system, Prior experience of the computer mediated communication, user satisfaction and utilization were analyzed. The instruments for the study were satisfaction(Kim, 2000), utilization(Kim, 2002). The collected data were analysed by descriptive statistics, using SPSS WIN 11.0 program. The results showed average score which is the satisfaction(6.09) showed middle satisfaction scores. It is concluded that if Nursing Knowledge Management System is operated considering all the above factors, It wound be one of the best qualified continuing clinical method for nurses.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

In this study, we examined their memories on science instruction and categorized them, and explored relationships between their emotional aspects and memory types. The study involved each three classes of the fifth- and sixth-grade students respectively who learned science topics through traditional ways. The amount of immediate memory on the instruction was highest in semantic one. In degrees of persistence of each memory type, which measured immediately and after one-week, the semantic and emotional memories decreased, whereas the episodic one increased. The more positive emotion the children had in science lesson, the more were total amounts of memories. In the positive emotional states, the proportion of semantic memory was higher than in the negative ones. On the other hand, episodic memory showed opposite trend. Boys and more episodic memories, whereas girls hand more semantic memories. The findings are discussed, including implications for science teaching.
