Extraction, Characterization, and Application of Agricultural and Food Processing By-Products

By-products originating from agricultural and food processing are considerable disposal problem for the industry because these waste streams emerge in huge quantities and often have direct impact on the economy and environmental pollution. However, at the same time, it constitute a rich but yet underutilized source of valuable components, which may find application as ingredients in the food and non-food industries. As a result, numerous projects are currently directed toward the utilization of agricultural and food processing by-products such as animal-based (skin, bone, flesh, and internal organs) and plant-based biomaterials (fruit peels and seeds, rice bran, and etc.). In the present work, we would like to focus on the potentialities and the current research of the compounds and extracts deriving from agro-industrial disposable wastes in the food-related utilization. The potential of selected by-products as a source of bioactive/functional compounds in terms of emerging and conventional techniques for extraction, characterization, biological activity monitoring and application of the extracts or isolated compounds as functional food ingredients or bio-based materials for food packaging are highlighted. Considering environmental effect and economic loss, agricultural and food processing by-products should be utilized in various innovative processes in the cause of beneficial product derivation

Students Transition from Primary to Secondary School at an International School in Bangkok, Thailand

The purpose of this study was to investigate if there was a significant difference in attitudes towards school, academic self-efficacy, and perceived social adjustment of Year 7, Year 8, and Year 9 students at an International School in Bangkok, Thailand. This research was a quantitative comparative design utilizing three questionnaires: the School Attitude Questionnaire by Seker (2011), the Academic Self -Efficacy subscale from the Self-Efficacy Questionnaire for Children by Muris (2001), and the Student Adjustment to College Questionnaire by Baker and Siryk (1984) to collect data in this study. The three questionnaires were combined for the current study into the Student Overall Adaptability to School Questionnaire. The researcher collected data from 222 students from Year 7 (71 students), Year 8 (78 students), and Year 9 (73 students).  The data were analyzed using descriptive statistics and a One-Way Analysis of variance for statistical hypothesis testing. The study indicated that the students had positive attitudes toward school. The academic self-efficacy towards school was moderate, followed by students' perceived social adjustment, which was slightly acceptable. There was a significant difference between the perceived social adjustment of Year 7, Year 8, and Year 9 students. Still, there was no significant difference between students' attitudes towards school and academic self-efficacy of the Year 7, Year 8, and Year 9 students. Recommendations are provided for teachers, parents, school administrators, school counselors, and future researchers. &nbsp

Policy Direction on Folk Music and Performing Arts Management in Thailand

The Research on Policy Direction on Music and Performing Arts Management in Thailand is a qualitativeresearch, aiming to study so as to determine policy direction on folk music and performancemanagement of the Department of Cultural Promotion. The results of this Research are as follows:1. According to the study of folk music and performance situation in Thailand, the music and localperformance in Thailand are different from those in a variety of regions, by having total 4 objectives;that is to say, 1) for funning and alleviating working tiredness, 2) for celebrating the achievement ofpersons or society, 3) for offering to Buddha in virtuous and meritorious activities, and 4) for conductingworship to the spirits and the angels or being used in rites and rituals. However, at present the importanceof music and local performance has tremendously reduced and has changed from the previous ones inthe form of showing forms, music instruments, dressings, and in particular change in roles and dutiestowards society as a result of change in society and economics. The survival of showings in society isdue to the things which are symbols and identities of a variety of local communities. In addition, thepublic sector continues to support various operations as appropriate; nonetheless, it is for the purpose ofconservation, rather than further development to add economic values.2. According to the proposal of policy direction on folk music and performance management of theDepartment of Cultural Promotion, the Researcher utilized concepts concerning management, theUNESCO Culture Production Cycle, and safeguarding of intangible cultural heritage guidelines underthe UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage as frameworks usedin study and determination of 8 issues used in preparing the proposal of the policy direction on folkmusic and performance management of the Department of Cultural Promotion, comprising 1. the policy/ management 2.

Integrated proteogenomic characterization of clear cell renal cell carcinoma

To elucidate the deregulated functional modules that drive clear cell renal cell carcinoma (ccRCC), we performed comprehensive genomic, epigenomic, transcriptomic, proteomic, and phosphoproteomic characterization of treatment-naive ccRCC and paired normal adjacent tissue samples. Genomic analyses identified a distinct molecular subgroup associated with genomic instability. Integration of proteogenomic measurements uniquely identified protein dysregulation of cellular mechanisms impacted by genomic alterations, including oxidative phosphorylation-related metabolism, protein translation processes, and phospho-signaling modules. To assess the degree of immune infiltration in individual tumors, we identified microenvironment cell signatures that delineated four immune-based ccRCC subtypes characterized by distinct cellular pathways. This study reports a large-scale proteogenomic analysis of ccRCC to discern the functional impact of genomic alterations and provides evidence for rational treatment selection stemming from ccRCC pathobiology
