The agitation of dementia patient is a factor which aggravates the care-givers' burdon, and it is needed to develop intervention methods. Hall and Buckwalter hypothesized that an increase in agitation behavior occur when persons experience high levels of stress. This study was conducted to explore the efficacy of hand massage in producing relaxation and decreasing agitation behaviors in persons with dementia. Hand massage was administered once a day in afternoon for 8days to 24 patients and 4days to 23 patients. There was no difference in result between the two groups. Significant differences were found in systolic blood pressure, pulse rate, emotional state from pre to post -intervention with the use of hand massage. The change of systolic blood pressure was 26% explained by ADL, MMSE-K and institutionalized period. The most significant variable was institutionalized period. The change of diastolic blood pressure was 11% explained by ADL, and it was significant. But no decrease in agitation behavior was observed and no increase in functional capacity.

The timing of poly(3-Hydroxybutyrate) (PHB) biosynthesis was controlled by varying the agitation speed of a stirred tank fermentor during the pH-stat fed-batch culture of recombinant Escherichia coli strain GCSC 6576 harboring pSYL107. Using a concentrated whey solution containing ca. 200 g/l lactose as the nutrient feed, the PHB content was only 57% after 35h due to volumetric limitation of the fermentor. However, by limiting the oxygen by maintaining the agitation speed at 300 rpm, the final PHB content increased to 70% after 70h with a cell concentration of 15 g/l. When the agitation speed was increased up to 500 rpm, a cell concentration of 31 g/l with 80% PHB was obtained after 52h. A further increase in the maximum agitation speed increased the cell concentration, PHB concentration, and PHB productivity, however, the PHB content decreased to 56-58%.

Purpose: The purpose of this review was to assess the quality and to evaluate the effectiveness of music interventions in reducing agitation in older adults with dementia. Methods: Randomized controlled studies and randomized crossover studies were identified by searching MEDLINE, EMBASE, CINAHL, PsycINFO, AGELINE, Cochrane Central Register of Controlled Trials, Korea Med, Kmbase, RISS, National Assembly Digital Library, KISS, and RICH. Two reviewers independently retrieved articles, extracted data, and assessed the quality of studies. Results: In total, 10 studies were selected from 1095 unique citations. All included studies were conducted in long term care settings. Overall, risk of bias for included studies was low to moderate. The weighted average effect size across studies was -0.39 (95%CI [-0.69, -0.10], p=.009, $I^2=63%$). Music therapy was effective to reduce agitation of the older adults with dementia. Conclusion: Music intervention can be an effective non-pharmacological intervention for the reduction of agitation in dementia. Future studies need to use rigorous research method and to provide description of research methods in greater detail. In addition, future studies are required to explore the effects of music therapy according to severity of agitation and dementia.

Purpose: The purpose of this study is to identify the effects of aromatherapy on agitation in patients with dementia using a meta-analysis and systemic literature review. Methods: The EMBASE, CINAHL, MEDLINE, and other databases were searched up to November 2017. Results: Of 419 publications identified, 12 met inclusion criteria, and 9 studies were used to estimate the effect size of aromatherapy. A total of 837 participants across all studies were included. The commonly applied methods were massage (50%), type of oil lavender (75%), and instrument Cohen-Mansfield Agitation Inventory (75%). A medium effect size of aromatherapy on agitation was identified (d=-0.56, $I^2=65.0%$, p=.001). The massage group has lower effect size than the other group (d=-0.98, $I^2=0.0%$, p=.001). Conclusion: Aromatherapy appears to be effective in improving agitation in patients with dementia. However, further studies for home-dwelling patients with dementia and with different types of aroma oil should be conducted in the future. In addition, research with well-designed are needed to assess the effects or aromatherapy on agitation.

플라이애시의 부유선별 과정에서 교반속도와 공기주입량과 같은 기계적 요소 변화에 따른 영향을 알아보고자 본 연구를 실시하였다. 본 연구에서는 미연탄소 함량이 약 3.4 ~ 3.7% 수준인 화력발전소 플라이애시를 사용하였다. 대표적인 부유선별의 선별 요소인 pH, 교반속도, 포수제 첨가량, 기포제 첨가량 변화에 따른 영향을 살펴보았을 때, Safflower oil을 포수제로 사용하여 첨가량을 800 g/ton, pH 7, 교반속도 1,200 rpm, 기포제 첨가량이 400 g/ton였을 때, 미연탄소 회수율과 미연탄소 함량이 각각 63%, 34%로 나타났다. 이 때 부상물 SEM/EDS 분석을 통해 알아본 결과, 구형의 플라이애시 미립자가 미연탄소 내에 고용되거나, 광액 내에 가라앉지 못하고 기포와 함께 부유함으로써 미연탄소의 함량을 낮추는 것으로 나타났다. 교반속도와 공기주입량과 같은 기계적 요소를 변화시킨 실험에서는 공기주입량 8L/min, 교반 속도 900 rpm에서 미연탄소 회수율 74%, 미연탄소 함량 67%인 것으로 나타났다. 이는 낮은 교반속도와 추가 공기주입으로 인하여 광액 내 와류의 강도가 낮아져, 미립의 플라이애시 입자가 미연탄소와 함께 부유되는 현상을 방지됨으로써, 미연탄소 회수율과 미연탄소 함량이 향상된 것으로 나타났다. 또한, 교반속도와 공기주입량을 각각 800 rpm, 6 L/min으로 설정하였을 때 미연탄소 회수율과 미연탄소 탄소함량이 각각 80%, 70%로 향상되어 가장 우수한 것으로 나타났다.

The influence of temperature and agitation on the growth of Escherichia coli expressing hepatitis B core antigen (HBcAg) in stirred tank bioreactor were investigated. The highest specific growth rate for E. coli$(0.844 h^{-1})$ was achieved at a temperature of $37^{\circ}C$ and an agitation speed of 250 rpm. The activation energy for the growth of the E. coli strain W3110lQ in the stirred tank bioreactor was estimated to be 11 kcal/mol. The highest protein yield was achieved at a temperature of $44^{\circ}C$ and an agitation speed of 250 rpm. The relative protein concentration at $44^{\circ}C$ is 30 and 6% higher compared to that at 30 and $37^{\circ}C$, respectively.

This study was carried out to investigate the effects of temperature activation and agitation on lipolysis of goat milk. When goat milk was temperature activated twice at intervals of 12hours, free fatty acids were significantly increased after the first activation, but increased slightly during the re-cooling period and after the second activation. Lipolysis of the goat milk warmed at $30^{\circ}C$ was significantly facilitated during the re-cooling period. Lipolysis of the goat milk warmed at $30^{\circ}C$ was much higher than those warmed at $10^{\circ}C$ and $40^{\circ}C$ respectively. The highest lipolysis was occurred when the goat milk was warmed at $30^{\circ}C$ for 5 minutes after pre-cooling for 24 hours at $40^{\circ}C$. However, any significant difference was not found in the milk warmed at $40^{\circ}C$, regardless of the pre-cooling period. Lipolysis of the goat milk warmed and agitated at $30^{\circ}C$ was significantly facilitated during the re-cooling period. The lipolysis of that at $30^{\circ}C$ was significantly facilitated during the re-cooling period. The lipolysis of that at $30^{\circ}C$ was much enhanced with agitation. The lipolysis was much higher when agitated at $30^{\circ}C$ than when agitated at $10^{\circ}C$. The length of agitation time at $30^{\circ}C$ didn't give any effect on lipolysis.
