We apply the Colour Family Drawing Test, as a development of the traditional black and white test, for cross-cultural comparison. The participants, aged 7 - 10 years, both genders, were examined individually. Each subject sat at a single table with a white rectangular card of standard size, 24 well-sharpened colour pencils, a black pencil, an eraser and other appropriate tools. S/he received this verbal instruction: “Draw your family”. The procedure was firstly applied to 120 participants attending primary schools of Rome (Biasi, Bonaiuto and Levin, 2014). The families were evaluated through a semi-structural interview conducted with the children’s teachers and divided into: Harmonious versus Very Conflictual Families. The drawings made by children of Harmonious Families consistently used “Reassuring and Playful Colours” (Pink, Orange, Sky Blue, Light Green, Light Yellow, other pastel colours);and were larger, tidier and more proportioned to respect the opposite group. Children belonging to Conflictual Families used mostly “Alarming and Serious Colours” (Grey, Black, Dark Bleu, Violet, Olive Green) and their drawings were less extended, more often disordered and had typical deformations such as figures too thin. A second investigation examined 120 participants belonging to Asian immigrant families residing in Italy. A third investigation examined 120 participants belonging to Russian families of moscow. Both last two investigations obtained very similar results on the use of colours, and gave a confirmation of the relevance of the Colour Family Drawing Test.

An innovative critique of existing studies on creativity has revealed the opportunity of distinguishing between different varieties of creative tasks, and namely creativity for “Continuity”, “Opposition” and “Detachment”, considering relations between products and perceived models. This theoretical contribution has led to a specific evaluation procedure: the COD Creativity test. Considering the influences of dynamic processes on creative processes, it is worth experimentally studying the effects of short-term stress or comfort treatments. The similarities and differences between various existing studies are examined. A non-invasive but effective procedure, compared to classic techniques, is described: the “drawing recall” of stressful or relaxing real experiences, accompanied by detailed evaluations of the emotional sphere. In a specific investigation, creativity turned out to be significantly lower after acute stress with respect to comfort treatment. In conclusion, the cognitive, decisional and activity processes involved in creativity operations can be considered as strictly reflecting emotional dynamic processes, as well as the experiences gained during the stress or comfort treatments. Results are explained considering the role of conflict overload in stress as a factor of incongruity and uncertainty intolerance, inhibiting the production of bizarre and unusual ideas and configurations, and thus reducing essential aspects relevant to the evaluation of creativity levels. From clinical point of view, we underline that decades of research has generally shown that being more rigid is associated with poorer mental health. Our experimental study gives confirmation of the link between stress and intolerance of uncertainty and incongruity;this correlation could augment the negative impact of stressors on anxiety levels. In summary, people with high level of intolerance of uncertainty and, generally, with high level of intolerance of incongruity, develop mental rigidity

An experimental assessment of the effectiveness of university counselling was conducted through the “Stress Drawing Recall” Technique applied before and after a clinical colloquium with 70 university students of both genders, aged 18 - 35 years, who had requested this service. Another 70 students waiting to undergo the colloquium were interviewed as a control group. Two parallel series of drawings depicting personal stress situations were collected and, after evaluation by three expert judges in “double-blind” conditions, led to establishing five forms of development of the graphic language from the first to second drawing, defined as follows: a) distension, with a reduction in stress indicators and increase in comfort indicators;b) explicit representation of conflict resolution;c) appearance of new elements, with persisting conflict;d) increase in stress indicators;e) invariant or equivalent repetition of the stress drawing. Results showed that students who underwent the clinical colloquium (experimental group) changed their stress drawings mainly in the direction of distension and conflict resolution, while the control group had more invariant or equivalent repetition of the stress situation (?= 62.77;p mited short-term stressful situations due to mainly external agents;b) externally induced stressful situations with intense emotional resonance;c) wide-ranging long-lasting stressful situations with great involvement of the self. The participants were divided into: a) very anxious subjects;b) averagely anxious subjects;c) not very anxious subjects, on the basis of their scores on two questionnaires: the mPI (1959) and the STAI (1970). There is a correspondence between the subjects’ level of conflict and extension of the depicted stress. This confirms the usefulness of the Stress Drawing Recall Technique in psychological counselling.

为了确定破囊壶菌Aurantiochytrium sp.的最佳破壁方法,分别使用反复冻融法、超声法、高速匀浆法、碱热法和研磨法对破囊壶菌进行破壁处理。为了解各方法的破壁效果,使用显微镜观察破壁前后的细胞个数变化,并利用SEm(Scanning Electron microscope)观察细胞的形态变化。为探究不同破壁方法对油脂提取的影响,首先使用尼罗红荧光染色法对油脂含量进行了定性检测,随后采用正己烷提取油脂。为探究不同破壁方法对油脂组分的影响,使用气相色谱法分析了油脂的组成情况。结果显示:(1)碱热的破壁效果最好,破壁率达到95.51%;(2)碱热破壁后得到的油脂产率最高,达到61.33%,远高于其他4种方法 ;(3)碱热破壁后得到的油脂中DHA含量最高、达到41.33%,相应的DHA产量也远高于其他方法、达到2.192 g/L。从制备高纯度DHA的角度出发,碱热法是最佳的破壁方法。

在许多国家,预应力混凝土箱梁被认为是中等跨径(30～50m)混凝土梁最有效的结构形式。但是当混凝土梁的单跨长度超过50m时,相对钢梁,混凝土箱梁自重问题成为其最大约束。因此,在韩国,中等跨径桥梁主要采用钢箱梁。在20世纪,研究者们多次尝试提高预应力混凝土箱梁结构的有效性,最终采用混凝土-钢混合梁以减轻结构自重。但是,混合桥采用不同类型钢腹板及不同连接形式,会引起结构安全性能和使用性能的变化。为了全面了解钢腹板梁及钢腹板连接形式的性能,对5根带腹板的预应力混凝土梁进行静力荷载试验。这5根试件中,有2根混合梁采用波形钢腹板,而另3根采用桁架式钢腹板。结果显示:通过加强钢腹板与预应力筋的连接节点,可以改善使用性能相关问题(开裂荷载和挠度)及安全性能相关问题(刚度和极限承载力)。
