Purpose: The purpose of this study was to investigate agitation in home-dwelling persons with dementia and coping behaviors of primary family care-givers to agitation. Methods: The research was designed as a descriptive study. A total of two hundred and five subjects had participated in this study. To measure agitation in persons with dementia, Cohen-Mansfield Agitation Inventory was used. To measure coping behaviors of primary family care-givers to the agitation, a questionnaire was used. Descriptive statistics, t-test, ANOVA, Scheff$\acute{e}$ test were used to answer the research objectives. Results: 'Repetitive mannerisms' and 'repeating sentences' were the most commonly occurred agitation in home-dwelling persons with dementia. 'Leaving the situation', 'allowing certain time', and 'soothing by talking' were the most common coping behaviors occurred in primary care-givers. Conclusion: The findings of the current study would provide meaningful data to develop nursing programs to control agitation for home-dwelling persons with dementia and education programs for primary care-givers to cope with persons' agitation.

Effect of ultrasonic agitation on the contact properties was studied in Ni electroless plating and Pd activation. P-type Si bare wafers were used as substrate and DMAB was used as reducing agent due to its good electrical properties, solderability and compatibility to substrate. In activation, high density Pd nuclei of small size were formed during ultra-sonic agitation compared to that of no stirring. In electroless plating, the plating rate was enhanced by 30∼90% by using ultrasonic agitation. In elecrtoless plating, inhibitor is the most effective additives in ultrasonic agitation. In this experi-ment, thiourea was used as inhibitor. The less the amount of the inhibitor, the more ultrasonic agitation efficiency. It is confirmed by SEM that Ni-B films formed by ultrasonic were coarser, less porous, and denser than those of no stirring. In ultrasonic agitation, boron content of the films was more than those of no stirring. In this case, the more DMAB concentration, the higher the temperature, the less pH, the more boron content. Resistivity of the films formed by ultrasonic agitation was higher than that of no strirring. As the content of boron was increased, the resistivity of the films was increased exponentially.

The unstirred water layer (UWL), which has been known to exist in the boundary of the intestinal lumen and intestinal wall, often behaves as an absorption barrier especially for lipophilic drugs. The intestinal absorption of drugs is often characterized using Caco-2 cell monolayers grown on Transwell polycarbonate membranes. The permeability $(P_{app})$ of drugs across the cell monolayer might be influenced by the agitation of the donor compartment, since the width of UWL on the surface of the cell monolayer would be reduced by the agitation. In this study, the effect of agitation of the donor compartment with 60 rpm on the permeability was measured for 12 drugs with a wide range of lipophilicity and permeability. The $P_{app}$ of mannitol, tributylmethyl ammonium, cimetidine, ranitidine, hydrocortisone, benzylpenicillin and loxoprofen was not influenced by the agitation, while the $P_{app}$ of theophylline, propranolol, YH439, phenylpropanolamine and testosterone was increased by the agitation. There was a significant correlation between the increase of $P_{app}$ by agitation and the lipophilicity for the compounds having $P_{app}>2{\times}10^{-5}$ cm/sec. No correlation was observed for the difference in $P_{app}$ by agitation and the molecular weight, or lipophilicity of the drugs. Therefore, the agitation rate of the donor compartment in the Caco-2 cell monolayer study should be carefully controlled in order to estimate $P_{app}$ reproducibly especially for lipophilic drugs.

The effects of agitation and aeration for exopolysaccharide(EPS) production through batch cultivation of an Enterobacter sp. isolated from the composter were investigated. During the EPS fermentation under conditions of constant agitation speed from 200 to 900 rpm and constant aeration rate of 0.5-2.5 vvm, the low yields of EPS(4.8-5.2g/L) was observed as the viscosity increase of culture broth. With the stepwise increases in agitation speed and aeration rate, the EPS production and the viscosity of EPS were increased 1.3~1.4 times and 2.3~3.6 times higher than those of the fixed conditions, respectively. Therefore, these stepwise increases were considered as the key operating parameters for enhancing EPS production. The max. EPS(6.8g/L) and viscosity(14,000cp) were obtained when the agitation speed was increased from 300 to 900 rpm for 54hrs at 1.5 vvm.

The effects of agitation rate and agitation time on the synthesis of sphingosome were studied. As increase in the agitation rates 4,000, 6,000, 8,000, 10,000 and 12,000 rpm the viscosity of sphingosome were decreased. The most sufficient agitation rate was 8,000rpm for which micell viscosity and stability. The effect of agitation time on the sphingosome viscosity and stability was investigated by changing the agitation times 2, 4, 6, 8 and 10 minute at 8,000rpm. 4 minute was the most sufficient for the viscosity and stability. The sphingolipid activity of cutaneous wound healing in impaired mice was examined. As a result, we could prove that phytosphingosine-HCl medically worked on wound healing well. For the phytosphingosine-HCl, it was found that the experimentally determined medical action more effective than that of tetra-acetylphytosphingosine.

The effect of solution agitation on the copper electroless deposition process of ULSI (ultra large scale integration) interconnections was investigated by using physical, electrochemical and electrical techniques. It was found that proper solution agitation was effective to obtain superconformal copper configuration within the trenches of $130{\sim}80nm$ width. The transition of open potential during electroless deposition process showed that solution agitation induced compact structure of copper deposits by suppressing mass transfer of cuprous ions toward substrate. Also, the specific resistivity of copper layers was lowered by increasing agitation speed, which made the deposited copper particles smaller. Considering both copper deposit configuration and electric property, around 500 rpm of solution agitation was the most suitable for the homogeneous electroless copper filling within the ultra-fine patterns.

Purpose: The feasibility and differential effects of two music therapy methods (interventions with preferred music vs. classical relaxation music) were done to examine the effects on agitation and anxiety in patients weaning off mechanical ventilation. Methods: This pilot study was conducted using a crossover design. Six patients listened to preferred music choices and classical relaxation music. Anxiety scores were measured using the Richmond Agitation Sedation Scale (RASS), State-Trait Anxiety Inventory (STAI), and visual analog scale (VAS). Results: Patients showed a significant decrease in agitation and anxiety after both the preferred and classical relaxation music interventions. The difference in the effects of preferred music and that of classical relaxation music was not significant. As for feasibility, patients exhibited a change in agitated behaviors after the music interventions by not trying to take off medical devices and quietly listening to the music, and by smiling and moving lips along with the lyrics while listening. Conclusion: Music interventions which centered on either patients' preferences or classical relaxation music to enhance relaxation, helped reduce agitation and anxiety during the mechanical ventilation weaning process.

Purpose: The purpose of this study was to provide basic data about agitation in patients with dementia by surveying the literature. Method: Key words used for search through hand-search and electronic database (CINHAL, Pubmed, Google scholar, Riss, Kiss, DBpia) included 'dementia', 'Alzheimer disease', 'agitation', 'aggression or aggressive behavior', 'problem or disruptive behavior', and 'abnormal behavior.' Seventeen studies met the inclusion criteria for the Meta-analysis and 'R' version 3.2.2 was used to analyze the correlated effect size. Results: Study results showed that variables related to agitation were identified as the demographic (age, gender), dementia-related (cognition, medication uses), physical (Activity of Daily Living [ADL], pain), psychological (depression, psychotic symptom, caregiver burden) and environmental (psychosocial environment) factors. The effect size between the correlated variables and agitation were low to moderate (caregiver burden .36; ADL -.24; psychotic symptom and depression .21; pain .19; cognition -.15; medication uses .12; and psychosocial environment -.12). Conclusion: Based on the findings of this study, strategies to improve patients' depressive and psychotic symptoms and ADL and to reduce caregivers' burden are needed for prevention and management of agitation in patients with dementia.
