The purpose of this study was to identify the effect on improvement of the Activity of Daily Living (ADL) and decrease the cognitive function and agitation behaviors by reminiscence with audio-visual stimulation for senile dementia. The quasi-experimental design was used in this study. Subjects were 26 with mild senile dementia who were cared for at a Day Care Center for Dementia in Seoul. The data were collected from March to July, 1999. Subjects were divided into three groups : Control Igroup with 10 subjects, reminiscence group(Control II group with 8 subjects), and reminiscence with audio-visual stimulation group(experimental group with 8 subjects). The Control I group got routine care as usual. Control II group participated in reminiscence sessions for one hour a day, five times a week , for a period of 4 weeks. The experimental group participated in reminiscence with audio-visual stimulation sessions for one hour a day, five times a week, for a period of 4 weeks. Instruments of this study were color photography with sound that was developed through an open questionnaire about events, objects, humans in action and animals that 100 Korean elderly over 60 would like to memorize. This was referred from the Sensory Stimuli Package by Namazi and Haynes(1994). The effects of treatment was evaluated through MMSE-K by Kwon & Park(1989). Also the Brief Cognitive Rating Scale(BCRS) by Reisberg et al(1983) for the cognitive function, through Agitation Inventory by Cohen- Mansfield and Colleague(1989) for behavioral response and through the Rapid Disability Rating Scale-2(RDRS-2) by Linn & Linn(1982) for the activity of daily living respectively. Data analysis was done using SPSS for $\chi$2- test, ANOVA, repeated measures ANOVA. The results were as follows : 1. Reminiscence with audio-visual stimulation did not improve cognitive function for senile dementia, but significantly improved verbal expression, the subscale of cognitive function. 2. Reminiscence with audio-visual stimulation reduced agitation behavior of experimental group significantly, but there was no significant difference between groups. 3. Reminiscence with audio-visual stimulation did not significantly effect the activity of daily living after treatment. In conclusion, it was shown that the reminiscence with audio-visual stimulation was an effective therapy to improve verbal expression and to reduce agitation behaviors of senile dementia. Further research with more indepth approach is needed, considering characteristic and level individualized for each senile dementia.

The disease patterns among the Korean was shifted from acute and infectious diseases to chronic diseases. According to the these disease patterns trends, people have concerned about the health promotion and health behaviors. Pender's(1996) revised health promotion model(HPM) is consist of three categories; Individual characteristics and experiences, Behavior-specific cognitions and affect, behavioral outcome. Of these categories, individual characteristics and experiences, this category of variables is considered to be of biological, psychological and socio-cultural personal factors, especially, individual fatigue. Futhermore. these variables constitute a critical core for nursing intervention, as they are subject to modification through nursing actions. But there is no few the research of the relationship between the fatigue and health promotion. Therefore, the purpose of this study is to investigate the correlation between the fatigue and health promoting life style among a rural college students. Additionally, this descriptive correlational study identified the relation of demographic factors and fatigue, health promoting life style. From June 20 to 26, 1998, a convenience sample of 270 college students completed the questionnaire of the fatigue and health promoting life style profile which were developed by the Yoshitake(1978) and Walker, et al.(1987), respectively. The descriptive correlational statistics, mean, t-test, ANONA, Pearson correlation coefficient were used to analyze the data gathered with SAS pc+ program. The results were as it follows: 1. The average fatigue score of the subjects was $64.93{\pm}12.89$. Fatigue scores by subcategory were physical symptoms($23.5{\pm}4.87$). psychological symptoms($22.11{\pm}4.66$) and neuro-sensory symptoms($19.32{\pm}5.14$). With the respect to the demographic characteristics of the subjects, there were statistically significant differences between the demographic factors and fatigue, especially, sex(t==3.69 p<0.01), major(t=-2.89 p<0.01). the experience of family illness(t=2.76 p<0.01). 2. The average health promoting life style item score of the subjects was $2.33{\pm}0.33$. In the subcategories, the highest degree of performance was self-actualization(2.94), following interpersonal support(2.81). stress management(2.33), exercise(2.20), nutrition(2.10), and the lowest degree was health responsibility(1.73). There were the significant differences on the learning of health education(t=2.00 p<0.01). religion(F=3.01, p<0.05), circle activity(t=2.07, p<0.05), nutrition control(t=5.25, p<0.01) of demographical factors with the health promoting life style. 3. The correlation between the fatigue and health promoting life style made statistically no significance(r=-0.09731, p>0.05). But there was negative significant relationship between health promoting life style and psychological symptom as a fatigue subcategory(r=-0.15721, p<0.05). The self-actualization showed negative significant correlation with all fatigue subcategory. The health responsibility showed significant relationship with total fatigue(r=0.13050. p<0.05). For further research, it suggests to replicate the correlational and causal study between the fatigue and the health promoting life style using the another fatigue scale which is able to measure the subjective and objective fatigue degree. And it needs to develop the nursing intervention program for maintaining and promoting the health behavior as well as for decreasing the college students's fatigue.

This study was performed to find out the differences between noise levels of hospital wards and the nurses efforts for noise management in some general hospitals. The hospital wards selected were the intensive care unit(ICU), the emergency room(ER), the nursery room(NR), the internal medicine(IM), the general surgery(GS) among the 5 general hospitals located in Seoul. The data were collected from August 3 to September 13, 1999 through questionnaire survey and noise measurement in each nursing station of hospital wards. Data analysis was done by SPSS 8.0 package among the 305 questionnaires and 24 hours monitored noise levels. Frequency, Chi-square and ANOVA test were used. The study results were as belows: 1. The noise level measured by 24 hours monitoring survey were exceeded on the standard limit in all the hospital wards. Data also showed that noise levels were significantly different in each ward among the three shifts working duties. 2. The subjects were all female nurses. They were mostly working in the ICU ward(28.9%). They were 26~30 years old (43.9%), junior college graduates(57.0%), working for 1~5 years(55.1%) as staff-nurse(85.6%). There were no significant differences between hospital wards and general characteristics of nurses. 3. The noise levels perceived by nurses were regarded as 'Highly noisy'(56.4%), especially during the 11:30 and 15:30 (30.2%) o'clock. Data also showed that noise education was not ever given to nurses(89.9%). Nurses also responded that they hardly put an effort to reduce noise level(54.8%). However, there were significant differences between wards and noisy working time, experience of noise education and level of effort for noise reduction. 4. Nurses also perceived the ventilator alarm and EKG-alarm as the most disturbing sounds in the ICU, human voice and telephone ringing in the ER, human voice and EKG-alarming in the NR, human voices and telephone ringing in IM and GS both wards respectively in order. There were significant differences between hospital wards and noise making factors. 5. Nurses were shown that they regarded highly 'Sound reduction of the human voice', 'Careful handling on medical instruments', and 'Immediate appliances on alarming materials' as the practical method for noise management. There were significant differences between hospital wards and behavioral practical efforts for noise management. According to that results, the statistical differences were shown in the 24 hour monitored noise levels in each ward. Also, nurses perceived the noise severity differently and they approached variously on the practical efforts for noise reduction in each ward. Thus, author thinks that concrete and systematic endeavor will be necessary for noise reduction and management in hospitals for better working and healing environment for both of patients and staffs.

Purpose: This study aims to offer the fundamental data in order to cost the nursing service on the basis of the NIC and a close examination of the interventions that are contained in the health insurance cost list under the system of the current health insurance. Methods: The data is handled with the SPSS 10.0 program. The participants' general peculiarity is calculated in terms of the real number and the percentage, and the performing frequency of the nursing interventions is calculated in terms of the mean and the standard deviation. the correlation between the participants' general peculiarity and the performing frequency of the nursing interventions is analysed with t-test or one way ANOVA of SPSS. Results: In the performing frequency of the nursing interventions, the domain of "the physiological: basic" was the highest as 2.69${\pm}$1.21, the domain of "the behavioral" was the lowest as 2.11${\pm}$1.12. There were 50 core interventions in the medical unit, 48 in the surgical unit, 24 in the MICU and 33 in the SICU. The health insurance cost items contained commonly in the core interventions of each unit were 12, and the health insurance cost items except 12 items contained commonly in the core interventions of each unit were appeared 14 items in the medical unit, 6 in the surgical unit, 7 in the MICU and 2 in the SICU. The core interventions contained commonly in four units of the medical unit, the surgical unit, the MICU & the SICU are 18. And among these, the core interventions contained in the health insurance cost items are 10; pain management, hyperglycemia management, analgegic administration, medication administration: intravenous, oxygen therapy, pressure ulcer prevention, fluid management, fluide monitoring, intravenous(IV) insertion, intravenous(IV) therapy. As the result of the comparison & analysis between the core interventions of the NIC and the health insurance cost items, the core interventions contained in the health insurance cost list are 21(29 as the health insurance cost items). Conclusion: In the performing frequency of the nursing interventions, the domain of "the physiological: basic" is being performed most frequently, and in the performing frequency of the core interventions, the interventions of the domain of "the physiological: complex" is being performed most frequently. On the basis of these results, the writer hopes that the attempts to interlink the nursing interventions into the nursing cost by using of standard terms and the efforts to cost the nursing services would also be made in the future constantly.

The effects of the oriental herbal medicine Saenghyetang(SHT, 生慧湯), which consists of Rehmanniae Radix (熟地黃 九蒸: was made by 9th steam) 40g, Corni Fructus(山茱黃) 16g, Polygalae Radix(遠志) 8g, Zizyphi Spinosae Semen(酸棗仁) 2g, Biotae Semen(柏子仁 去油: oil ingredient was removed) 20g, Poria Cocos(茯笭) 12g, Ginseng Radix(人蔘) 12g, Acori Graminei Rhizoma(石菖蒲) 2g, Sinapis Semen(白芥子) 8g, on learning ability and memory were investigated. Hot water extract(HWE) and ethanol extract(EE) from SHT were used for the studies. Learning ability and memory are related to modifications of synaptic strength among neurons that interactive. Enhanced synaptic coincidence detection leads to improved learning ability and memory. If the NMDA receptor, a synaptic coincidence detector, acts as a graded switch for memory formations, enhanced signal detection by NMDA receptors should enhance learning ability and memory. It was shown that NR2B was increased in the forebrains of oriental medicine-administrated mice, leading to enhanced activation of NMDA receptors and facilitating synaptic potentiation in response to stimulation at 10-100 Hz. These HWE-SHT treated mice exhibited that superior ability in learning and memory when performing various behavioral tasks, showing that NR2B is enhanced by HWE-SHT treatment and also is critical in gating the age-dependent threshold for plasticity and memory formation. NMDA receptor-dependent modifications, which were mediated in part by HWE administration, of synaptic efficacy, therefore, represent a mechanism for associative learning ability and memory. Results suggest that oriental medical enhancement of NR2B contributes to increase intelligence and memory in mammals On the other hand, to examine the effects of EE-SHT on the learning ability and memory in experimental mice, EE-SHT was tested on passive and active avoidance responses. The EE-SHT ameliorated the memory retrieval deficit induced by ethanol in mice, but not other memory impairments. EE-SHT(10, 20mg/100 g, p.o.) did not affect the passive avoidance responses of normal mice in the step through and step down tests, the conditioned and unconditioned avoidance responses of normal mice in the shuttle box, lever press performance tests and the ambulatory activity of normal mice in a normal condition. However, EE-SHT at 20 mg/kg significantly decrease the spontaneous motor activity during the shuttle box test, and also to extend the sleeping time induced by pentobarbital in mice. These results suggest that SHT has an ameliorating effect on memory retrieval impairments and a weak tranquilizing action.
