Effects of Different Chair-Based Exercises on Salivary Biomarkers and Functional Autonomy in Institutionalized Older Women

Purpose: The aim of this study was to test the effects of chair-based exercise programs on salivary stress hormones, physical fitness, and functional autonomy of institutionalized older women. Method: In total, 47 participants (80 ± 8.04 years old) were recruited and allocated into three groups: chair-based aerobic exercises (CAE, n = 19), chair-based elastic-band strength exercises (CSE, n = 15), and a control group (CG, n = 13). A 14-week exercise intervention was done for the CAE and CSE groups, two times per week, in no consecutive days. Members of the CG did not participate in any type of exercise but kept their regular lifestyle. Fear of falling, autonomy, physical fitness, salivary cortisol, and alpha-amylase levels were assessed before and after the intervention. Results: The CAE group improved upper and lower body strength, agility–dynamic balance, and autonomy, with fear of falling decreasing significantly (p < .05, moderate effect size). Both exercise groups showed a trend toward an increase in salivary alpha-amylase levels (CAE = 43%, d = .31, and CSE = 44%, d = .41). Conclusion: Both exercise programs were able to improve functional autonomy, even in elders older than 80 years of age. It might be interesting to investigate the effectiveness of combining both aerobic and strength exercises in a unique protocol. The modulation effect of exercise in the hormonal responses needs to be further explored.     

Extended Validation of the Korean Version of the Quality of Life Survey

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.     

Application of time-temperature superposition method in thermal aging life prediction of shipboard cables

The life of shipboard cables will decrease due to the complex aging processes. In terms of the safety perspective, remaining life prediction of the cable is essential to maintain a reliable operation. In this paper, firstly, based on Arrhenius equation, residual life of new styrene-butadiene cable is calculated; result indicates that the degradation rate which changes with time is proportional to thermal temperature. Then second order dynamic model is adopted into the residual life prediction, combined with the time-temperature superposition method （TTSP）, and a new residual life model is proposed. According to the accelerated thermal aging experiment data and Arrhenius equation, TTSP method demonstrates to be an efficient way for life prediction, and life at normal temperature can be estimated by this model. In order to monitor the state of styrene-butadiene cable more accurately, an improved residual life model based on equivalent environment temperature of cable is proposed, and life of cable under real operation is analyzed. Result indicates that this model is credible and reliable, and it provides an important theoretical base for residual life of cables.

论新课改背景下课程观的转向

课程改革体现着一定社会特定历史时期的课程价值取向。要构建符合时代精神融合素质教育理念的课程体制，就必须改变传统的、封闭的旧课程观，树立新型的、开放的大课程观。新时代课程观的转向实质是人与知识、教育与生活、课程与教学这三对关系的转向．是向完整的人及其完整的生活的转向。     

灵视——华兹华斯诗艺建构的核心

华兹华斯是一个灵视诗人。华氏的灵视力首先表现在其作品中强烈的生命意识：诗人坚信世间万物皆有神性,死亡是生命的延续;同时,华兹华斯的灵视力使他把自然当作传达情感的强有力的工具,在诗人的眼中,自然是人类接近上帝的媒介,是人类灵魂的导师,最能激发想像力的工具,是人类精神的伊甸园;华兹华斯还是是一个热衷于描写人类精神世界的大师,他喜欢选择贫苦的农夫、儿童、心智不全者以及老人作为他文学创作的对象,通过对他们精神世界的探索,诗人成功的展示了那沉静而永在的人性的悲曲中所渗透的人性的崇高。     

农村老年人社会支持与生活质量的相关研究

采用《社会支持评定量表》和《生活质量量表》对河北省农村老年人进行抽样调查。结果表明,农村老年人的社会支持对生活质量有显著影响,不同来源的社会支持对生活质量的影响不同,其中主观支持的影响更为显著。要改进农村老年人的社会支持、提高生活质量,就要充分发挥政府职能和家庭养老功能,同时改进农村老年人及其家庭成员的养老意识。

Addressing Intercultural Experience and Academic Mobility in Higher Education

The present study initially discussed the various aspects of interculturality in higher education and the value of intercultural experience for developing intercultural competence. Then, it investigated the relationship between intercultural experience and students’ progress in their studies from prep year to senior years. The findings indicate that students do not gain intercultural experiences as a natural outcome of progress in higher education. Afterward, the relationship between intercultural experience and motivation for academic mobility was researched. According to the results, having foreign friends and attending intercultural events could be taken as predictors of lenience towards student exchange programs. Finally, the motivating and deterring factors of academic mobility for the participants were determined, and suggestions for future research were made. Participants were 207 students from different study years at a university in Turkey. A mixed questionnaire was employed to obtain data related to students’ intercultural experiences and their perceptions concerning the benefits and barriers of academic mobility.     

Between Tradition and Change: Hunting as Metaphor and Symbol in State Socialist Hungary

Through the historic metaphor of hunting the essay examines the lifestyle of the dominant elites of Hungary between 1945 and 1990 on the basis of archival documents, private records, and oral history interviews. The analysis emphasizes the fact that there were interactions between the old, prewar aristocracy and the new state socialist elites. The co-incidence of lifestyles can be viewed through the lens of social and cultural change: new elements hit against the old, shaping and dissolving old behavioural patterns. The article analyses hunting in the contexts of social differentiation and social grouping. Using semiotics the author shows how, even during the era of state socialism, power and social distinctions were articulated on the level of lifestyles, and transmitted via the social, semiotic function of behaviours, patterns of taste, and forms of interaction. Thus, hunting evolved into a metaphor over time in Hungary: it was not only an indispensable part of the everyday life of the elite, but also became a symbol for belonging to it.
