Abstract: Now a days learning activities for environmental education or environmental studies mainly focus on the integration of people s ways of life into the learning activities by examining the social contexts and environment around the learners so that the learners would have direct experience from nature enabling them to learn meaningfully. Besides, at present, the ideas of sufficiency economy philosophy have also been integrated into learning and teaching activities of environmental studies aiming to inculcate the learners to follow the essence of the philosophy which consists of three pillars: moderation, reasonableness and self-immunity and two conditions: knowledge and integrity. The purposes of this research were three fold: to develop the learning activity entitled Life and Environment following the sufficiency economy philosophy for Prathomsuksa 6 students, to compare the learning achievements of the students before and after using the learning activity and to compare the students attitudes towards environmental conservation before and after using the activity. The samples were 30 Prathomsuksa, 6 students studying in the second semester of the 2008 academic year at Sapradoo School, Wichianburi District, Petchaboon Province. The experiment was carried out using one group pretest-posttest design. The research instruments included five learning activity plans, learning achievement tests: pretest and posttest and a questionnaire on attitude towards environmental conservation. The results revealed that the learning activity entitled Life and Environment following sufficiency economy philosophy was effective at 81.67/82.92 which is higher than the 80/80 set-level, the students significantly had higher learning achievement after using the learning activity at the 0.05 level and the students significantly had a higher level of positive attitude towards environmental conservation at the 0.05 significance level.

Abstract: Mobile learning (M-learning) is a new, exciting and promising field. M-learning likely to provide more information rather than knowledge, misses the mark. Information and knowledge are not identical, however the students face some problems and difficulties such as chances to learn, practice and time consuming. This is because experts and media are not enough for them. M-learning is a one thing for creates a variety of ways to deliver and provide electronic resources for learner. It includes many methods such as using system to deliver text, video and animation to learner. Thus, M-learning is professionals cite benefits to learner. The learner benefits from the opportunity to prepare themselves for greater ability increase their competitive in a globalization. This study was designed the interactive M-learning for information system education to visual assistant method for learning and developing ability of students. Researcher used the technique of dynamic computer graphics to establish an animation display system. Therefore, the purposes of this research were to develop the interactive M-learning of Management Information Technology course for information system education based on ADDIE Model and to evaluation the interactive M-learning of Management Information Technology course for information system education. The samples of this study comprised of 30 students from Rajamangala University of Technology Rattanakosin, Thailand. The sample was obtained by using the simple random sampling method and used one-group pre-/post-test evaluation design. The results shown that the satisfaction of the panel experts and information system students on the system, the mean was 3.70 with the standard deviation was 0.63, the satisfaction was in the high agree level. In part of one-group pre-/post-test evaluation has shown that the post-test score higher that pre-test score. This can be concluded that the developed system can be utilized for this course.

Abstract: An on-line flow injection analysis (FIA) system for determination of lead (II) in water samples with a preconcentration step and spectrophotometric detection was investigated. The system is based on preconcentration of lead (II) on a column packed with Amberlite XAD-4 resin and detection by means of 4-(2-pyridylazo)resorcinol (PAR)–lead complex formation with maximum absorption at 523 nm. Chemical and FIA variables influencing performance of the system were optimised. Two linear calibration curves with a range of 0.01 - 0.40 and 0.40 – 0.80 mg L-1 were obtained. The developed system allowed a throughput rate of 16 samples h-1 with a 9-fold enrichment factor and a detection limit of 7 μg L-1. Relative standard deviation for 10 replicated injections of 0.25 mg L-1 was 2.3%. Recoveries of the method were in the range of 80-94 %. The procedure was validated by analysis of lead (II) in real water samples, and the results were statistically compared with those obtained by flame atomic absorption spectrophotometry (FAAS). The results obtained both by the proposed method and by FAAS were in good agreement.

Fixed Point Theory and Applications , 2010, DOI: 10.1155/2010/756492
Abstract: We introduce a new iterative scheme for finding a common element of infinitely nonexpansive mappings, the set of solutions of a mixed equilibrium problems, and the set of solutions of the variational inequality for an α-inverse-strongly monotone mapping in a Hilbert Space. Then, the strong converge theorem is proved under some parameter controlling conditions. The results of this paper extend and improve the results of Jing Zhao and Songnian He(2009) and many others. Using this theorem, we obtain some interesting corollaries.

Jintana Sanwong,Worachead Sommanee
International Journal of Mathematics and Mathematical Sciences , 2008, DOI: 10.1155/2008/794013
Abstract: Let () be the full transformation semigroup on the set and let (,)={∈()∶?}. Then (,) is a sub-semigroup of () determined by a nonempty subset of . In this paper, we give a necessary and sufficient condition for (,) to be regular. In the case that (,) is not regular, the largest regular sub-semigroup is obtained and this sub-semigroup is shown to determine the Green's relations on (,). Also, a class of maximal inverse sub-semigroups of (,) is obtained.

Boorapa Singha,Jintana Sanwong
International Journal of Mathematics and Mathematical Sciences , 2011, DOI: 10.1155/2011/489674
Abstract: Suppose that is an infinite set with ||≥≥?0 and () is the symmetric inverse semigroup defined on . In 1984, Levi and Wood determined a class of maximal subsemigroups (using certain subsets of ) of the Baer-Levi semigroup ()={∈()∶ dom = and |?|=}. Later, in 1995, Hotzel showed that there are many other classes of maximal subsemigroups of (), but these are far more complicated to describe. It is known that () is a subsemigroup of the partial Baer-Levi semigroup ()={∈()∶|?|=}. In this paper, we characterize all maximal subsemigroups of () when ||>, and we extend to obtain maximal subsemigroups of () when ||=.

Abstract: A model of community hen egg farm was selected at an iodine deficiency endemic area in North Eastern part of Thailand. The process for the preparation of high content iodine enriched hen food was demonstrated to the farm owner with technical transfer in order to ensure the sustainability in the long term for the community. The iodine content of the produced iodine enriched hen eggs were determined and the iodine status of volunteers who consumed the iodine enriched hen eggs were monitored by using urine iodine excretion before and after the implement of iodine enrichment in the model farm.The content of iodine in eggs from the model farm were 93.57 μg per egg for the weight of 55 - 60 g egg and 97.76 μg for the weight of 60 - 65 g egg. The biological active iodo-organic compounds in eggs were tested by determination of the base-line urine iodine of the volunteer villagers before and after consuming a hard boiled iodine enriched egg per volunteer at breakfast for five days continuous period in 59 volunteers of Ban Kew village, and 65 volunteers of Ban Nong Nok Kean village. The median base-line urine iodine level of the volunteers in these two villages before consuming eggs were 7.00 and 7.04 μg/dL respectively. After consuming iodine enriched eggs, the median urine iodine were raised to the optimal level at 20.76 μg/dL for Ban Kew and 13.95 μg/dL for Ban Nong Nok Kean.The strategic programme for iodine enrichment in the food chain with biological iodo-organic compound from animal origins can be an alternative method to fortify iodine in the diet for Iodine Deficiency Endemic Areas at the community level in Thailand.Iodine deficiency disorders (IDD) had been widely recognized as one of the important public health problems especially in developing countries throughout the world [1]. Thailand, one of the developing countries in South East Asia has started the public health activities on elimination of IDD endemic areas since 1989. In 1991, a national survey on total go

Abstract: Introduction: We studied the characteristics and treatment outcomes of the following risk groups for tuberculosis (TB): those with HIV and diabetes mellitus (DM), contact cases, the homeless, foreigners, health care workers (HCW) and the elderly. Method: A descriptive cross-sectional study was conducted by analysing the Japanese TB surveillance data of all cases registered between 2007 and 2010 (N = 96 689). Results: The annual proportion of TB cases by risk group was stable over the study period, although there was a slight but significant increase observed for foreigner and elderly cases. Homeless and elderly TB cases had the highest DM co-morbidity (16.6% and 15.3%), respectively. HIV co-infection was low in all TB cases (0.2%) yet highest in foreigners (1.3%). HIV status of 45% of TB cases was unknown. The proportion of multidrug-resistant TB (MDR-TB) was similar among all risk groups (0.0%–0.9%) except foreigner, at 3.4%. Males in most risk groups had higher mortality than females; the mortality of all TB cases in all age groups for both males and females was 3.6–24 times higher than the general population. Discussion: Reasons for the high proportion of “HIV status unknown” should be investigated and improved. Contact tracing among foreign cases with MDR-TB should be a priority. Homeless persons should be screened for DM together with TB. Programmes to enhance health and nutrition status may benefit TB prevention among the elderly. Tuberculosis screening and TB education are important for HCW.

Abstract: Problem: The 2008 tuberculosis (TB) surveillance of Chiang Rai Hospital, Chiang Rai, Thailand reported that 8.4% of Thai, 22.7% of hill tribe minority and 25% of migrant patients (n = 736) defaulted from treatment. Context: TB patient management in Chiang Rai is complicated due to poverty and HIV stigma. A previous study shows unaffordable travel expense was one of the reasons of patient default. Action: We engaged Chiang Rai women’s organizations whose members are of high socioeconomic status to support poor TB patients financially and socially. A group of women formed a team to support these TB patients (n = 192) by raising and sustaining funds and providing home visits (n = 37). TB surveillance and patient-fund register data were used to evaluate TB treatment outcomes. Outcome: The success of TB treatment was significantly higher for patients receiving financial support (relative risk [RR]: 1.351; 95% confidence interval [CI] 1.20–1.53; P < 0.000). Lower death rates in all groups were observed among patients receiving financial support. However, financial assistance alone did not improve treatment outcomes for migrant patients. Thirty-seven patients (25 Thai, eight hill tribe, four migrants) who were visited by women volunteers at home achieved 95% TB treatment success. Discussion: It is possible to involve volunteers to support poor TB patients. Willingness to support TB patients was driven by presenting provincial TB epidemiology information, research data on the experience of poor patients and the inspiring experiences of other women volunteers. Future research should investigate the reasons for the high treatment success among patients who received home visits.
