Background: This study aimed to determine the effectiveness of aroma hand treatment in alleviating fatigue and promoting relaxation of mothers in their early postpartum period. Methods: This is a quasi-experimental study with a two-group pretest-post-test design which used purposive sampling and non-random assignment of 242 consenting Japanese early postpartum mothers who were patients from a hospital maternity unit in Tokyo, Japan. The intervention involved a 20-minute aroma hand treatment using an effleurage method. The participants selected from 5 essential oils: pure lavender, ylang-ylang, citron, rosewood, and sweet orange. Relaxation promotion and fatigue alleviation as the main outcomes were measured using self-administered valid and reliable questionnaires. Statistical analysis was performed using the two-sample t-test, two-way factorial ANOVA, and simple main effect test. SPSS ver. 23.0 (SPSS, Chicago, IL, USA) was used for data analysis at a 5% significance level. Results: Of 242 participants (intervention group, n = 122;comparison group, n = 120), 229 participants (intervention group, n = 115;comparison group, n = 114) were analyzed per protocol. The intervention group showed a significant improvement in relaxation (t = 6.43, p < 0.001). A significant difference in the simple main effect test of relaxation (F = 37.58, p < 0.001) was found. However, there was no significant reduction in fatigue. The majority (88.4%) of the participants indicated high satisfaction with the aroma hand treatment, and 90.5% evaluated the length of intervention time as appropriate. Conclusions: The aroma hand treatment effectively promoted relaxation of early postpartum mothers, but was less effective in alleviating their fatigue. Based on their high satisfaction rate, aroma hand treatment using essential oils may be considered effective in promoting relaxation of early postpartum mothers.

Open Journal of Fluid Dynamics 2012年第4期2卷 337-342页

作者： nao Kuniyoshi Minoru Yaga Akito Koda Isao Teruy Masaaki Ishikawa Department of Mechanical System Engineering University of the Ryukyus Okinawa Japan Graduate School of Engineering and Science University of the Ryukyus Okinawa Japan Makino Milling Machine Co. Ltd. Tokyo Japan

In this experiment, the effects of the combination of jets or rods and a porous cavity on the supersonic flow field are studied by means of visualization of schlieren method and the measurements of wall static pressures and the flow direction in the cavity with the thermal tuft probe. Three cases of jets or rods arrangements are tested in the experiments. As a result, a bow shock wave which is generated by the jets or rods is observed by mean of schlieren method. And it is confirmed that the expansion region appears downstream of the rods but is not in case of the jets pattern. Moreover the pressure ratios of starting shock wave passing through porous cavity for jets pattern differ from that of rods pattern. In the cavity, the flow direction at the measurement position in the cavity is always opposite to the main flow, as long as the starting shock wave is located upstream of the porous cavity for all cases. Difference in the backward flow ratio between the jets and rods patterns is observe after the starting shock wave passes through the porous cavity.

为了研究碳纤维布(CFRP)加固后砂浆的动态强度和破碎特征,利用直径50 mm分离式Hopkinson试验装置开展不同冲击气压下普通砂浆和CFRP加固砂浆的动态压缩试验。基于孕育时间准则,分析了砂浆试件的应力率灵敏性以及瞬时峰值强度的增大趋势。结果表明:在试验的应力率范围内,普通砂浆和CFRP加固砂浆的峰值应力均随着应力率的增加而增加,而临界时间呈缩短趋势,CFRP加固砂浆的临界时间相比于普通砂浆要滞后9~61.7μs,且应力率越大,临界时间滞后的幅度越小;普通砂浆和CFRP加固砂浆的孕育时间分别为54.2μs和72.1μs,不同的孕育时间表明它们的应力的动态增长效应不同,CFRP加固砂浆的应力的动态增长效应大于普通砂浆;CFRP加固砂浆试件出现分层断裂现象,随着应力率的增大,CFRP加固砂浆的破碎特征逐步接近普通砂浆。

On the basis of a long-term（30 years） field experiment that involved four rotation systems, rice-rice-winter fallow（RRF）, rice-rice-ryegrass（RRG）, rice-rice-rape（RRP）, and rice-rice-milk vetch（RRV）, this study described the effects of green manure on the microbial communities in the red paddy soils using 454 pyrosequencing for the 16 S r RNA gene. The Chao1 richness and non-parametric Shannon＇s index increased in all soil samples that received green manure treatments. The communities＇ structures with the green manure applications were significantly dissimilar from that under the winter fallow. Using Metastats tests, many genera in the RRG, RRP and RRV soils were significantly different from those in the RRF soil, including a number of genera that functioned in the nitrogen and sulfur cycles. Analyses of the genera with these functions revealed the shifts in microbial ecosystem functions after long-term green manuring. Changes in the microbial communities increased the ammonium supply and decreased the soil acidification in green-manure-amended soils. Together, these data suggested powerful effects of green manure on both the microbial communities and the biogeochemical cycle driven by the shifts in bacterial functional groups.

砂岩储层中由流体注入导致的地震活动与砂岩断层(裂隙)的摩擦行为有关.为了揭示不同温度条件下含流体砂岩裂隙的摩擦特性,在温度范围为25°C~140°C和有效法向应力范围为4~12 MPa的试验条件下,本文分别对干燥、水饱和以及注CO_(2)锯切砂岩裂隙进行了速度分级加载试验.试验结果表明:(1)对于干燥砂岩裂隙,增大有效法向应力和升高温度均能增大裂隙的初始摩擦系数,而改变有效法向应力对裂隙摩擦稳定性影响不明显,仅升高温度会略微降低其摩擦稳定性;(2)对于水饱和砂岩裂隙,裂隙的初始摩擦系数同样会随着有效法向应力的增大而增大,但会受到升温的弱化作用,而增大有效法向应力和升高温度均能降低裂隙的摩擦稳定性;(3)对于注CO_(2)砂岩裂隙,裂隙的初始摩擦系数受有效法向应力和温度变化的影响与水饱和砂岩裂隙相反,但裂隙的摩擦稳定性仅会随着温度的升高而降低,受有效法向应力的影响不明显.因此,砂岩裂隙的摩擦特性受有效法向应力、温度和注入流体类型的共同影响.该试验结果对理解流体注入诱发地震有一定的指示作用.

International Journal of Nursing Sciences 2017年第2期4卷 99-104页

作者： Yoko Imazu nao Matsuyama Sanae Takebayashi Mizue Mori Setsuko Watabe Tokyo Medical and Dental University TokyoJapan Yokohama City University Hospital YokohamaJapan Yokohama City University YokohamaJapan Department of Nursing Graduate School of MedicineYokohama City University Yokohama236-0004Japan

Purpose: In the era of antiretroviral treatment (ART), treatment of HIV has become more manageable, and most patients with HIV benefit from long-term therapy in Japan. The aim of this qualitative study was to examine the experiences of patients with HIV/AIDS receiving mid-and long-term care in Japan. Methods: A qualitative study was performed using semi-structured interviews at an outpatient clinic of a university hospital in the Greater Tokyo area. A total of 31 Japanese patients with HIV who had been receiving treatment for at least a year were interviewed in Japanese. Data from these interviews were analyzed by'content analysis' (Krippendorff, 1980). Results: The data were organized into the following seven themes:"feelings toward diagnosis of HIV infection";"perceptions and behavior after diagnosis of HIV";"attitudes toward HIV therapy";"fear and hope for the future";"feelings toward professional support";"life changes after HIV therapy";and"struggles in relationships with others". Conclusions: Some participants accepted themselves as HIV-positive, some did not when they were diagnosis. This difference of reaction had effect on attitudes toward HIV therapy. But all participants continued mid- and long-treatments owing to feeling well and receiving support from professionals. Additionally, it found that patients were felt stigma of HIV-positive similarly to another Asian countries. Therefore, we should provide the entire Japanese society with knowledge about HIV/AIDS and be early and constant intervention by professional teams after being infected.

The relationship between the thermohaline circulation and climate variability

引用

Chinese Science Bulletin 2000年第11期45卷 1052-1056页

作者： zhou Tianjun ZHANG Xuehong WANG Shaowu State Key Laboratory of Atmospheric Sciences and Geophysical Fluid Dynamics(LASG) Institute of Atmospheric PhysicsChinese Academy of SciencesBeijing 100029China Geophysical Department Peking UniversityBeijing 100871China

The long-term integration with the Global Ocean-Atmosphere-Land System model of the State Key Laboratory of Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), Institute of Atmospheric Physics(IAP), Chinese Academy of Sciences has been used in the investigations on the relationship between the thermohaline circulation and climate variability. The results show that the strength of the North Atlantic Thermohaline circulation (THC) is negatively correlated with the North Atlantic Oscillation (nao). Based on this kind of relationship, and also the instrument-measured climate record such as air pressure and sea surface temperature, the activity of the thermohaline circulation during the 20th century has been evaluated. The inferred variations of the strength of the THC is that, during two multi-decadal periods of 1867-1903 and 1934-1972, the THC is estimated to have been running stronger, whereas during the two periods of 1904-1933 and 1973-1994, it appears to have been weaker.
