Purpose: The purpose of this study was to identify premorbid personality, depression and disturbing behaviors to provide information for developing nursing interventions for the pre-demented and mild demented elderly living as residents of their community. Method: The survey was conducted through direct interviews using a structured questionnaire in J city. Among the subjects contacted, 89 made appropriate replies to the survey. Result: The subjects' disturbing behaviors were significantly related to premorbid personality and depression. The predictors to disturbing behaviors of the pre-demented elderly were sex, extroversion, neuroticism and conscientiousness. The predictors to disturbing behaviors of the mild demented elderly were agreeableness, depression, sex, conscientiousness, and extroversion. Conclusion: In conclusion, disturbing behaviors of pre-demented elderly and mild demented elderly are affected not only by their premorbid personality but also by their depression. Therefore, it is necessary to encourage and respond to them with understanding their disturbing, behaviors in 'relation to their premorbid personality. In addition. it is important to maintain positive emotion in order to reduce their disturbing behaviors.

Purpose: This study was conducted to investigate correlations between environmental characteristics and disturbing behaviors in elderly people with dementia living in institutions. Method: A random sample of 107 subjects in three institutions for people with dementia in the Gyeongnam Province was tested between May 29 and June 5, 2002. Data was collected through a questionnaire and analyzed using SPSS/PC Win 10.0 Result: The major findings of the study are as follows. 1) the mean score on physical environment was $3.55{\pm}0.47$, and on psychosocial environment, $3.55{\pm}3.08$. 2) the mean score on disturbing behaviors showed that nonaggressive psychomotor behavior was the highest, and aggressive psychomotor behavior was the lowest. 3) the disturbing behaviors. in 5 the domains correlated with the environment and influencing factors included environment, family, level of dementia and level of ADL. Conclusion: Both the present physical environment and psychosocial environment influence the type of disturbing behavior in elderly people with dementia. Therefore, nursing can reduce the disturbing behaviors through maintenance of both the psychosocial environment and the physical environment. Furthermore, nurses must consider disturbing behaviors of elderly people with dementia by being aware of the level of dementia and ADL.

Sleep is a necessity for survival. Disruption of sleep leads to numerous adverse physiological and psychological consequences. These could be particularly undesirable for older patients, who are subject to many additional factors. But there is limited research related to hospitalized elderly in Korea. The purpose of the study is to explore sleep patterns and disturbing factors of before and after hospitalization, in order to present basic information regarding elderly sleep to develop nursing intervention. The sample consisted of 32 elderly men and women between the ages of n and 87 years. Data collection was done from September to November 1997. Measures of sleep patterns and related factors were obtained from self-reported sleep questionnaires. Analysis of data was done by use of t-test, paired t-test, ANOVA, and Pearson Correlation Coefficient. The results of this study were summarized as follows : 1. In comparision between before and after admission of their sleep pattern, “sleep onset” tends to be delayed and nocturnal sleep time was significantly reduced. So, hospitalized elderly reported less total sleep time than before admission. 2. Regarding the sleep disturbing factors, medication(hypnotics ; 37.5%), physiological factor (snoring ; 59.4%) environmental factor (pillow ; 78.1%), emotional factor(anxiety related to disease ; 37.5%), and illness factor(fatigue ; 34.7%) were reported. 3. Significant differences in gender were found. Men had more disturbances in sleep than women owing to difficulty in falling a sleep and lack of nocturnal sleep. Women consumed more sleep inducing drugs. Significant increase was reported in napping during the day with increasing age. 4. Significant differences between good sleepers and poor sleepers were found for the following variables : nocturnal sleep time, total sleep time, bed time, sleep onset latency time, sleep latency time after nocturnal awakening, time spent in bed upon arousal, environmental factors, and emotional factors. In conclusion, it was found that the quantity and quality of sleep were significantly altered in hospitalized elderly, but adequate strategies for better sleep were not practiced. Further research is needed to develop Intervention strategies to promote sleep and to prevent sleep problems.

As a descriptive survey, this study was attempted to get basic data necessary to recognize the factors that disturb the therapeutic atmosphere of hospital wards as perceived by nurses and hospitalized patients, to identify differences between the perceptions of the nurses and of patients. The subjects, 159 patients in Pusan National Hospital and 68 nurses working there were sampled between March 18 and April 13, 1996. The tool used to measure the disturbing factors was an amended form of the one developed by Kim, Mae Ja(1983). The differences between each subject's score for each factor were analyzed using means & SD. and the highest 3 items above the mean score for each factor were collected and compared. The results are described below : 1. Subject's perception of main disturbing factors : patients reported that the main factors were 'loss of role & economic trouble', 'the prognosis of disease', 'the change of daily life' but nurses replied that the main factors were' the prognosis of disease', 'the communication trouble with the medical team & interpersonal relationships'. 'The change of daily life' was not a perceved factor by nurses, but ranked third by the patients. 2. Subject's perception degree of each disturbing factor : (1) among the items related to interpersonal relationship. the patient group reported that the worst disturbance was dur to severely ill patients in the same room' but the nurse group regarded 'greed to monopolize wheelchairs or other supplies' as the worst disturbance. (2) among the items related to physical factors. the patient group regarded 'limitations to wash their body, physical pain and limitations in physical activity' as the worst disturbance, but the nurse group regarded' physical pain', and 'limitations to activity or change of appearance' as the worst disturbance. (3) among the items related to the change of daily activity, the patient group regarded 'the boredom of hospitalization or infavorable diet' as the worst disturbance, but the nurse group regarded 'too much noise or unclean room' as the worst disturbance. (4) among the items related to the communication trouble with medical team, the patient group regarded 'the ignorance of their disease due to poor information. the inability to understand the language of the medical team or the difficulty in seeing physician in time' as the worst disturbance, but the nurse group regarded 'the inability to trust physicians and physician's poor attention to patients' as the worst disturbance.

To improve the sensing accuracy of the newly developed magnetically suspended sensitive gyroscope (MSSG), it is necessary to analyze the causes of drift error. This paper build the models of disturbing torques generated by stator assembly errors based on the geometric construction of the MSSG with double spherical envelope surfaces, and further reveals the generation mechanism of the drift error. Then the drift error from a single stator magnetic pole is calculated quantitatively with the established model, and the key factors producing the drift error are further discussed. It is proposed that the main approaches in reducing the drift error are guaranteeing the rotor envelope surface to be an ideal spherical and improving the controlling precision of rotor displacement. The common problems associated in a gyroscope with a spherical rotor can be effectively resolved by the proposed method.

In this work, wind tunnel tests of pressure measurements are carried out to assess the global aerodynamic interference factors, the local wind pressure interference factors, and the local lift spectra of an square high-rise building interfered by an identical cross-sections but lower height building arranged in various relative positions. The results show that, when the interfering building is located in an area of oblique upstream, the RMS of the along-wind, across-wind, and torsional aerodynamic forces on the test building increase significantly, and when it is located to a side, the mean across-wind and torsional aerodynamic forces increase; In addition, when the interfering building is located upstream or staggered upstream, the mean wind pressures on the sheltered windward side turn form positive to negative and with a maximum absolute value of up to 1.75 times, and the fluctuating wind pressures on the sheltered windward side and leading edge of the side increase significantly with decreasing spacing ratio (up to a maximum of 3.5 times). When it is located to a side, the mean and fluctuating wind pressures on the leading edge of inner side are significantly increased. The three-dimensional flow around a slightly-shorter disturbing building has a great effect on the average and fluctuating wind pressures on the windward or cross-wind faces. When the disturbing building is near to the test building, the vortex shedding peak in the lift spectra decreases and there are no obvious signs of periodicity, however, the energies of the high frequency components undergo an obvious increase.

Purpose: The purpose of this study was to investigate the current humidification state of incubator, the factors disturbing high humidification and to establish the evidence-based nursing protocol to maintain it. Methods: The subjects were 15 infants who were born with extremely low birth weight (ELBW) from May to October, 2007, and data were collected during the first 3 days and analyzed with SPSS WIN program. Results: The goal of humidity level in incubator was 95%, but mean humidity levels were 89.7%(1st day), 91.9%(2nd day), and 91.8%(3rd day)(p<0.001). The disturbing factors were opening frequency and duration of incubator door and window by caregivers. The handling of infants by nurses and doctors happened more frequently during the first day. Especially, nurses handled them more often than others, but the duration of opening during the invasive procedures by doctors was longer than others. The opening frequency had negative correlation with duration(r=-.779, p<.01). Conclusion: So the evidence-based protocol for maintaining high humidity in incubator for ELBW infants during the first 3 days and next 2 days was made. Furthermore we need to educate NICU nurses and doctors about minimal handling.

The soil loss by rainfalls or runoffs has been one of the main environment problems in 20th century. The soil loss cause the various problems those are decreasing of the agricultural productivity, desolating of pasture land and disturbing of water flowing. Therefore, it is very important to measure properly various factors those are affecting to soil loss and to recognize a seriousness of soil loss problem. In this study, we use the USLE(Universal Soil Loss Equation) as a basic approaching way for soil loss analysis in a watershed, and the GSIS(Geo-Spatial Information System) technique is applied to evaluate for factors those are related to the USLE. The results of this study are consisted of three parts those are to build up the various topographical information that is needed for analysis of wide area soil loss by using the USLE, to evaluate the factors those are needed to the USLE, to estimate the soil loss condition of subbasin in the watershed.
