Montfortian Education Charter (MEC) in the Modern Age: Responding to Global Challenges

This article deals with the commitment of the Religious Educators, Montfort Brothers of St. Gabriel, in Thailand and worldwide to cope with changes in the 21st Century. Though their three-hundred-year education system and pedagogy are founded upon the founder's charism and firm belief in the eternal 'Absolute Truth,' GOD ALONE, the Montfort Brothers of St. Gabriel acknowledged and responded to constant changes in the world. In response to demands of changes in the 21st Century, 16 years (1992-2008) of revising and updating their educational heritage under the 'Montfortian Education Charter' (MEC) was successes. Due to their sincere commitment to education mission inherited from their founder and God's inspiration, the contents of MEC coincide very well with the latest discoveries of educational guidelines for the 21st Century-Partnership for 21st Century Skill and Wagner's Seven Survival Skills for 21st century students.

Masculinized Labor Activism and Geographies of Household Reproduction in Thailand’s ‘Detroit’

This PhD dissertation project focuses on the collective agency of Thai organized workers—a group of regional migrant workers in one of Thailand’s most industrialized areas—whose labor geography and organizations were conditioned by Thai state-capital-labor relations. It examines how the social, political and geographical organizations of Thai workers shape their practices of labor activism. By linking workers’ ties to their place of origin with the new geography of automotive production in Thailand’s Eastern Seaboard, this dissertation examines the agency of workers through labor activism and its relationships to migration—a geographical mechanism that bridges production and reproduction across workers’ multi-sited households. This dissertation builds on the critical traditions within Human Geography as well as the work of feminist geographers to center the role of households and cultural practices of labor activism. By bringing together processes of production and social reproduction often examined separately, it sheds light on the ways in which gender and class politics within labor activism are inextricably linked to the division of labor within spatially extended households of Thai migrant workers. It highlights how workers draw on their collective resources (i.e. the regional ethnic culture) and social reproductive network stretched across the geography of household reproduction, which sustain labor struggle strictly seen in the sites of production

Production of Generation-2 Mekong giant catfish (Pangasinodon gigas) cultured with Spirulina sp.

The purpose of this study is to evaluate the treatment of Spirulina-supplemented pellet feed to 5-year-old F1 groups of Mekong giant catfish (Pangasinodon gigas) from the brood stock and intended for use as breeders. The effects on their growth and maturation when cultured in an earthen pond were observed. Results revealed that, compared to control, there was more gain in weight while the feed conversion ratio was lower. The number of red blood cells was also higher while that of white blood cells was lower, compared to control. Out of 18 treated fish (9 males and 9 females), 6 males and 2 females gave sperms and eggs while none from control group did. It was concluded that Spirulina supplemented in pellet feed can improve growth and maturation performance to the brood stock of Mekong giant catfish

Social Media Marketing Strategy and Marketing Performance: Evidence from E-Commerce Firms in Thailand

Undeniably, social media has come to a higher degree of popularity in the online world. Currently, most businesses have been utilizing any social media platforms for social media marketing in their strategy. Yet, in this sense it still has to be explored concerning how social media marketing strategy affects marketing performance. Therefore, this paper aims at investigates the relationship between dimension of social media marketing strategy (SMMS) and marketing outcomes. The questionnaires of 298 e-commerce firms in Thailand were collected. Regression analysis was employed to verify the hypotheses. The evidence highlights that market response timeliness orientation has the strongest positive significance for all marketing outcomes. Both product diversity presentation awareness and proactive competitor learning capability are significantly positive to marketing operation excellence. Furthermore, the findings also suggest that each dimension of SMMS required either marketing operation excellence or increased customer satisfaction as a mediator variable effect on marketing performance. The finding not only provides contributions but also recommendation for future research

Synthesis and evaluation of modified oximidine analogues as anticancer agents and of terephthalaldehyde-bis-guanylhydrazones as endotoxin sequestering agents

Part I. The natural products oximidine I and II are potent and selective anticancer agents at nanomolar concentrations. Their structures and potent cytotoxicity are similar to the recently discovered natural products salicylihalamides, apicularens, and lobatamides, which are members of the benzolactone enamide family. However, it is believed that the enamide, a crucial moiety for anticancer activity, will be labile under physiological conditions. This has led to our hypothesis that the replacement of the enamide moiety with a stable warhead will allow the discovery of novel anticancer agents with improved pharmacokinetics. We selected three different warheads that are likely to be stable under physiological conditions and that could undergo nucleophilic addition like the enamide. We prepared by total synthesis oximidine analogues that carry a vinyl sulfone, a boronic acid and an α -keto oxadiazole instead of the enamide side chain. Based on CoMSIA/QSAR analysis, we have designed, prepared and evaluated new analogs of oximidine II. Part II. Lipopolyamines bind to the lipid A moiety of lipopolysaccharide, a constituent of Gram-negative bacterial membranes, and neutralize its toxicity in animal models of endotoxic shock. In an effort to identify non-polyamine scaffolds with similar endotoxin-recognizing features, we had observed an unusually high frequency of hits containing guanylhydrazone scaffolds in high-throughput screens. We now describe the syntheses and preliminary structure-activity relationships in a homologous series of bis-guanylhydrazone compounds decorated with hydrophobic functionalities. These first-generation compounds bind and neutralize lipopolysaccharide with a potency comparable to that of polymyxin B, a peptide antibiotic known to sequester LPS

Study of Seasonal Heat, Freshwater, and Volume Transports in the Gulf of Thailand using an Ocean Circulation Model

This research aims to investigate volume, heat, and freshwater transports in the Gulf of Thailand for each season. The Model grid used in this research is the orthogonal curvilinear grid which is constructed via cubic splines and solving Laplace's equation. For the vertical grid, the sigma coordinate is introduced to deal with significant topographical variability. The data used consist of bottom topography, current velocities, potential temperature, salinity, and seawater density, which are calculated from the primitive equations. The results show that the highest and lowest values of volume, heat, and freshwater transports in each season occur at the same region, and the direction of volume and heat transports are all same in the Gulf of Thailand, but the freshwater transport is in the opposite direction of volume and heat transports. The highest values of volume, heat, and freshwater transports occur between latitudes 7°N to 8°N in the winter and at the connection section between the Gulf of Thailand and the South China Sea in the summer, rainy season, and the end of the rainy season.  Their lowest values occur at latitude 11°N in the winter, between latitudes 8°N to 9°N in the summer, and between latitudes 10°N to 11°N in the rainy season and the end of the rainy season. In order to validate the results, a comparison was made with the results of Wyrtki's research which investigated the volume transports of Southeast Asian Waters. It can be summarized that the results of our research are on track

Route planning of heterogeneous unmanned aerial vehicles under recharging and mission time with carrying payload constraints

Purpose: We consider the problem of route planning of multiple rechargeable heterogeneous UAVs with multiple trips under mission time and payload carrying constraints. The goal is to determine the types and number of UAVs to be deployed and their flying paths that minimizes the monetary cost, which is a sum of the recharging energy cost of each UAV, the UAV rental cost, and the cost of violating the mission time deadline. Design/methodology/approach: The problem is formulated as a mixed integer programming (MIP). Then, the genetic algorithm (GA) is developed to solve the model and the solutions are compared to those obtained from the exact method (Branch-and-Bound). Novel chromosome encoding and population initializations are designed, and standard procedures for crossover and mutation are adapted to this work. Test problems on grid networks and real terrains are used to evaluate the runtime efficiency and solution optimality, and the sensitivity of GA parameters is studied based on two-level factorial experiments. Findings: The proposed GA method can find optimal solutions for small problem sizes but with much less computation time than the exact method. For larger problem sizes, the exact method failed to find optimal solutions within the limits of time and disk space constraints (24 hours and 500 GB) while the GA method yields the solutions within a few minutes with as high as 49% better objective values. Also, the proposed GA method is shown to well explore the solution space based on the variation of the total costs obtained. Originality/value: The unique aspects of this work are that the model optimizes the sum of three different costs – the electricity recharging cost, the UAV rental cost, the penalty cost for mission deadline violation, and the recharging period based on the remaining energy, the payload capacity, and the heterogeneity of UAVs are incorporated into the model. The model is formulated as a mixed integer programming and the genetic algorithm is developed to solve the program. Novel chromosome encoding and population initializations are designed, and standard procedures for crossover and mutation are adapted to this work
