The Efficacy of Integrated Sfbt Intervention on Self- Compassion, Self-Determination, and Solution-Focused Mindset Among High School Students in Bangkok, Thailand

This research was conducted to investigate the causal relationship model of how self-determination impact on solution-focused mindset of high school youths in Thailand, being mediated by self-compassion. Thaitranslated instruments of the observed variables were developed and the psychometric properties were tested to measure their validity and reliability. Data from 500 high school students in Bangkok area were collected for Study I and Study II. The result from CFA analysis found all the translated instruments to be valid and reliable. In study II, the result of path model analysis showed that self-determination has both direct and indirect influence on solution-focused mindset, with the variable of self-compassion as a mediator. An experiment was conducted in study III to test the efficacy of the integrated SFBT intervention via an intervention group (n=25) vs control group (n=25). The finding showed that the designed intervention program was effective in increasing participants’ level of self-determination, selfcompassion, and solution-focused mindset

Kinetik der Inaktivierung von Mikroorganismen durch Wasserunlösliche Polymere mit antimikrobieller Aktivität

In der vorliegenden Arbeit werden Fortschritte diskutiert, die in der Biozidforschung durch die Entdeckung der neuen antimikrobiellen Polymere AMINA® T 100 und Poly-TAAMA erzielt wurden. Beide Polymere sind Entwicklungsprodukte der Degussa AG. Es wurde die Kinetik der Inaktivierung von Pseudomonas aeruginosa, Listeria innocua und Saccharomyces cerevisiae untersucht. Die Untersuchung der antimikrobiellen Wirksamkeit von antimikrobiellen Polymeren erfolgte unter verschiedenen experimentellen Bedingungen, um Schlüsse bezüglich der möglichen Wirkungsweise zu ermöglichen. Weiter wurden mittels Flow-Cytometrie Untersuchungen durchgeführt, in denen Listeria innocua einer hydrostatischen Hochdruckbehandlung (HHP, high hydrostatic pressure), einer Behandlung mit gepulstem elektrischen Feld (PEF, pulsed electric field) und kombinierten Behandlungen aus AMINA® T 100 mit HHP oder PEF unterzogen wurde. Daneben wurde das Verfahren des Geleinschlusses mit antimikrobiellen Polymeren angewendet. Bei den kombinierten Behandlungen ergab sich selbst für niedrige Konzentrationen von AMINA® T 100 und HPP oder PEF niedriger Intensität ein bemerkenswerter synergistischer Effekt. Nach Verwendung von Ca-Alginat als Gelmatrix führte die Gelstärke jedoch zu einer beträchtlichen Schwächung der membranzerstörenden Wirkung von AMINA® T 100. Unter dem Gesichtspunkt der Wirtschaftlichkeit könnte ein viel versprechendes Vorgehen darin zu bestehen, antimikrobielles AMINA® T 100 in Kombination mit HHP oder PEF niedriger Intensität anzuwenden, um Mikroorganismen zu inaktivieren und zugleich geschmackliche Qualitäten und Nährwert von Lebensmitteln, die dieser kombinierten Behandlung unterzogen werden, so weit wie möglich zu erhalten.This thesis discusses advances in the biocides sciences through the discovery of the new antimicrobial polymers AMINA® T 100, and poly-TAAMA. Both polymers are developmental products of Degussa AG. The inactivation kinetics of Pseudomonas aeruginosa, Listeria innocua, and Saccharomyces cerevisiae were investigated. The antimicrobial efficacy of antimicrobial polymers was examined under different experimental conditions in order to draw conclusions about the possible mode of action. Furthermore, Listeria innocua exposed to high hydrostatic pressure treatment (HHP) and pulsed electric field treatment (PEF) and combined treatments of AMINA® T 100 with HHP or PEF by flow cytometry was performed. In addition, the method of gel encapsulation with antimicrobial polymers was conducted. The combined treatments gave a remarkable synergistic effect even at low concentrations of AMINA® T 100 and low intensities of HHP or PEF. After using Caalginate as gel entrapment, gel strength reduced the membrane-degradative effect of AMINA® T 100. In terms of economical benefits, it seems to be a promising approach to use antimicrobial AMINA® T 100 in combination with low intensities of HHP or PEF to inactivate microorganisms while maintaining the maximum degree of sensory and nutritional qualities of food materials subjected to this combination treatment

Effect of phenolic compounds on the oxidative stability of ground walnuts and almonds

Walnuts and almonds are mainly constituted by unsaturated fatty acids and, in consequence, are readily prone to oxidation reactions. These nuts are also rich in antioxidant substances such as polyphenols, which are mainly concentrated in the brown skins (BS) or seed coats. This study analyzes the effect of BS phenolic compounds on the oxidative stability of walnuts and almonds. For this reason, peeled and unpeeled ground nuts were comparatively evaluated after thermal treatments as well as after room temperature storage. Furthermore, volatile compound emission due to thermally induced oxidation of the ground nuts was analyzed using HS-SPME-GC-MS. Several secondary oxidation products were identified in the headspace, and volatile product formation was considerably larger in nuts with BS than in peeled ones. Consistently, the former showed higher malondialdehyde levels after heating which indicates a prooxidant effect of BS presence. In order to verify these findings, a water-in-oil microemulsion was used as a model system to assess the role of nut phenolic compounds on lipid oxidation promotion. The hydroperoxide and malondialdehyde content was determined, as a measurement of primary and secondary oxidation enhancement, respectively. A dose dependent prooxidant effect on linoleic acid thermal oxidation was also observed when BS polyphenolic extracts as well as pure phenolic compounds were added.Fil: Salcedo, Cecilia Luciana.
