Abstract: The present environmental condition is in crisis and it is getting worst as day pass. The main problem is the educational administration and the long range solution of this problem. It is very important that the administration should have knowledge, opinion and good environmental behavior. The aims of this study are: Development of training program to reinforce the guide of environmental study for educational institute administrator under Kalasin educational service area office zone 1. To test and compare the knowledge before and after the training and to reinforce the guide of environmental education for educational institute administrator in 5 factors. To test the opinion of the guide of environmental study for educational institute administrator. To study and compare the result performance of environmental study for educational institute administrator in 5 factors according to experience and size of educational institute. To study the behavioral condition of guide in changing the environmental study for educational institute administrator in 4 factors namely, influential, motivation, stimulate to use the intellectual and individual relationship determination. The people are the administrator of educational places and 40 deputy directors in educational department of secondary school under Kalasin educational service area office 1 with tools use for this research are the training program, questionnaire to examined the knowledge, questionnaire to examined the opinion, questionnaire to examined the guide of modification and questionnaire to evaluate the environmental study performance and the statistic applied in this research are in percent, average point, standard deviation, t-test and F-test (One-way ANOVA and One-way MANOVA). The research shows that: The training programs developed by research and development is as qualified as the specified criteria. After the training, the institution administrators gained the leadership as knowledge in very high level of over 80%, as attitude is in high level and as the performances in environmental education within the institution is in high level as well. The institution administrators gained the leadership as knowledge in general and in each area are in very significantly high level comparing to their knowledge and leadership before the training, or 0.5 according to the statistic. The institution administrators has a better attitude towards environmental education leadership as knowledge in general considering in each area, mostly in the highest level. The performances of the institution administrators result in the environmental education within the institutions in general and those areas are high comparing to the experiences of administration in different institutions, the performances in the environmental education within the institutions are similar in general. Considering in each area, the institution administrators who got >10 years experiences have better performances than those who are in the pos

Abstract: Lampao Dam is the biggest irrigation in Thailand, meant exclusively for agricultural purposes, construction of the earthen dike and non-electricity, was begun in 1963 and complete in 1968. Impacts of the Dam construction caused significant changes of the Lampao community ways of life in Kalasin province in the environmental, economic, social and cultural aspects. Therefore, the objectives of this research were to study the environmental, economic, social and cultural factors affecting community changes and characteristics of community ways of life before and after the construction of Lampao Dam. The study focused on three village communities in 3 different districts of Kalasin province: Sa-adnathom, Donyanang and Sithan in Muang, Yangtalad and Kamalasai districts respectively. A qualitative research, it started with a review of literature and related researches. Field data were collected by way of in-depth interviews, participative and non-participative observations and focus group discussion, involving 46 key informants consisting of village elders, formal village leaders, informal leaders, farmers, government officials and NGO workers. The data were descriptively analyzed and deductively interpreted. The research findings were found; before the dam construction, people in the 3 communities believed in the interconnectedness of traditions revolving around the worship of ancestral spirits and popular Buddhism which undergirded their unity and their sense of respect and protection of the environment. Their ways of life were simple. Their leaders served as links with the past and guides for future generations. After the dam construction, people in these three communities began to change all this; the changes were forced upon them by state authorities, most clearly manifested in the construction of Lampao Dam. Their traditional beliefs began to weaken. Capitalist ways of life began to creep in and eventually overtook them. However, after a few decades people began to realize the danger. They fought and sought new ways to get out of their debts and hardships. Finally, they have found going back to live in harmony with nature relying on natural resources for their livelihood pointed the way. Happily, this path coincides with the Royal philosophy of Sufficiency Economy. This is where they are now. But their future is far from being certain. In conclusion, the Lampao Dam will be there for good. Many villagers regard it as "the BIG Farmland" from which they can benefit. On the other hand, the Lampao Dam had drastically changed the natural environment as well as ways of economic, social and cultural life. In the case of the three villages under study, the changes have been at least problematic. Since the beginning they had not been consulted at all. The lesson, therefore, is this: before undertaking a project which will affect people s ways of life, the government authorities should seek people s participation and take their well-being into serious consid

Abstract: Humans day by day have more behaviors in promoting pollution to the world by being unaware of the facts, causing impacts on all humans themselves. Creation of awareness of the environment is regarded as a guideline for helping decrease environmental pollution crises. Thus, this study of promotion of the environmental, ethical thinking system aimed to find out an efficiency of the Buddha Chinnaraj teaching approach with a requirement of 80/80, to compare ethical achievement before and after learning and to compare the environmental, ethical thinking system using the Buddha Chinnaraj teaching approach and the conventional teaching approach. The sample used in this study consisted of 80 Matthayumsueksa 5 (grade 11) students at Phutthachinnarat Phitthaya School, Amp hoe Mueang, Changwat Phitsanulok, obtained using the cluster random sampling technique. They were assigned to an experimental group of 40 students and a control group of 40 students. The instruments used for collecting data were plans for organization of learning by using the Buddha Chinnaraj teaching approach and plans for organization of learning by using the conventional teaching approach, a 40-item achievement test and a 40-item scale on ethical thinking. The statistics used for analyzing the collected data were mean, percentage, t-test (dependent samples) and F-test (ANOVA and Two-way MANOVA). The results of the study were as follows: the Buddha Chinnaraj teaching approach entitled promotion of the environmental, ethical thinking system had an efficiency of 96-25/96.87, which was higher than the established requirement of 80/80. After learning by using the Buddha Chinnaraj teaching approach Matthayomsuekas 5 students had higher knowledge, attitudes and performance in the environmental, ethical aspect than those who learned using the conventional teaching approach at the 0.01 level of significance. fter learning by using the Buddha Chinnaraj teaching approach Matthayomsueksa 5 students had higher environmental ethics than those who learned using the conventional teaching approach at the 0.01 level of significance. In conclusion, the Buddha Chinnaraj teaching approach, which has principal dharma and dharma principles in supplement as the base of the yonisomanasikara thinking system and reasons as important elements. This approach can encourage students to be alert and to generate dharma preference and originate happiness to living things around them. The students have mental freedom based on the Buddhist Teachings. Therefore, the Buddha Chinnaraj teaching approach should be supported to implement in learning and teaching in the future.

Abstract: Organization of environmental conservation learning-teaching activities at the primary education level can be regarded as importance to living in the future. In the violently natural changing condition there should be an appropriate model of learning and teaching the learner development activities. This study aimed, to examine efficiencies of the inquiry, collaborative and integrated teaching methods entitled Environmental Conservation with a requirement of 80/80 and to compare learning achievement, attitudes, behaviors and learning The population used in this study consisted of Prathomsueksa 6/1 students, Prathomsueksa 6/2 students and Prathomsueksa 6/1 students, 30 students each, totally 90 students. The instruments used in this study were 15 plans for organization of inquiry learning, collaborative learning and integrated learning a 40 item achievement test, a 30 item scale on attitude toward environmental conservation and a 30 item scale on environmental conservation behavior. The statistics used for analyzing the collected data were men, percentage, F-test (ANOVA) and one-way MANOVA. The results of the study could be summarized as follows: The inquiry collaborative and integrated learning entitled Environmental Conservation for Prathomsueksa 6 had efficiencies (E1/E2 ) of 84.47/82.66, 84.84/83.58 and 90.12/87.50, respectively which was each higher than the established requirement of 80/80. The students who learned using the inquiry, collaborative and integrated teaching methods had different learning achievement at the 0.01 level of significance. The students who learned using the integrated teaching method had higher learning achievement than the collaborative and inquiry teaching methods. The students who learned using the inquiry, collaborative and integrated teaching methods had different attitudes toward environmental conservation at the 0.01 level of significance. The students who learned using the integrated teaching method had higher attitudes toward environmental conservation than the collab0vative and inquiry teaching methods. The students who learned using the inquiry, collaborative and integrated teaching methods did not have different environmental conservation behaviors. The students who learned using the inquiry, collaborative and integrated teaching methods had different learning retention at the 0.01 level of significance. The collaborative teaching method had higher learning retention than the integrated and inquiry teaching methods. In conclusion, the model of environmental conservation learning by using the integrated teaching method was appropriately efficient and could develop learning achievement, attitudes and environmental conservation behaviors of the students at the primary education level. Therefore, teachers should be promoted and supported to implement the int3eegrated teaching method in organization of learning and teaching environmental conservation at every primary education class level.
Acute aortic dissection: utilizing imaging modalities to improve detection

Abstract: Acute aortic dissection is a serious condition in eld-erly patients and may become fatal rapidly if left undiag-nosed and untreated. As pointed out by Welch et al1 chest radiography is a screening test for this condition by detecting these signs such as widening mediastinum, blurring of the aortic knob, left apical cap, etc. Unfortu-nately these signs on chest radiography may not be sensi-tive enough to detect acute aortic dissection.1'2 There-fore, if patients have high clinical likelihoods of ihe aortic dissection including old age, crushing chest pain, hyper-tension, pulse deficit, known history of thoracic aneu-rysm, or Marfan' s syndrome, etc, further diagnostic test is required to exclude this deadly disease even normal chest radiography.2'3 Other imaging modalities include aortography, transesophageal echocariogrpahy ( TEE ) , magnetic resonance imaging ( MRI) , or computerized to-mography (CT). "'? Currently, aortography is not routine-ly performed to diagnose this condition because it may worse the situation if the catheter is placed into the false lumen. Noninvasive modalities have increasing role be-cause they can detect dissection very accurate and provide the information of the wall and near by structures. " This is so important because it has been recognized that acute aortic syndrome is a spectrum of the diseases including acute aortic dissection, penetrating aortic ulcer, intramu-ral hematoma, and aortic rupture.4' 5 Each imaging mo-dality has strength and weakness for detecting this syn-drome. Transesophageal echocardiography provides ade-quate diagnostic accuracy, evaluates the involvement of aortic valve, determines cardiac function, and importantly can be performed at the bedside in this sick individual, however, the distal part of ascending thoracic aorta and proximal aortic arch area is a blind spot in a number of patients due to the air-filled trachea and left mainstem bronchus interposed between the esophagus and this part of the aorta." The false positive results may be due to reverberation artifacts, calcified plaque, therefore, other imaging modality may help to improve the detection if TEE is nondiagnostic. Magnetic resonance imaging is known to be an excellent modality to determine these con-ditions with high accuracy.3'4'6 The extent of the disease can be completely assessed with MR angiography and car-diac and valve function can be assessed as well. Due to large field of view, the involved surrounding structure and aortic wall can be assessed. Unfortunately, the examina-tion is in a closed space and if patients are in critical con-dition, it may not be an ideal situation due to safety con-cern. The MRI examination is contraindicated in patients with cardiac pacemaker, automatic implantable cardio-verter-defibrillators, intracranial aneurysm clips, or oto-logic implants, etc." Recently, the development of multi-detectors CT scanner allows very fast image acquisition and provides information in aortic pathology, as we

Abstract: In this issue of the Journal of Geriatric Cardiology, Huang et al. have reported the detection of coronary artery disease with electron-beam computed tomography (EBCT), utilizing non-contrast and contrast imaging techniques (EBCTA) in several subgroups including type 2 diabetes mellitus (DM), impaired glucose tolerance (IGT), coronary heart disease, and normal subjects. Interestingly, non-contrast imaging by measurement of the coronary artery calcium score (CAC) did not show any differences among the groups. However, the presence of coronary calcification and/or coronary stenotic lesions detected by contrast coronary angiography with EBCTA was found more frequently in type 2 DM, IGT, and coronary artery disease patients than in healthy subjects. The authors concluded that combined information on either CAC or luminal assessment with EBCTA should be considered for assessment of atherosclerosis in type 2 DM patients.

Songklanakarin Journal of Science and Technology , 2012,
Abstract: The analyses of clinical and epidemiologic studies are often based on some kind of regression analysis, mainly linearregression and logistic models. These analyses are often affected by the fact that one or more of the predictors are measuredwith error. The error in the predictors is also known to bias the estimates and hypothesis testing results. One of the proceduresfrequently used to handle such problem in order to reduce the measurement errors is the method of regression calibration forpredicting the continuous covariate. The idea is to predict the true value of error-prone predictor from the observed data, thento use the predicted value for the analyses. In this research we develop four calibration procedures, namely probit, complementary log-log, logit, and logistic calibration procedures for corrections of the measurement error and/or the misclassification error to predict the true values for the misclassification explanatory variables used in generalized linear models. Theprocesses give the predicted true values of a binary explanatory variable using the calibration techniques then use thesepredicted values to fit the three models such that the probit, the complementary log-log, and the logit models under the binaryresponse. All of which are investigated by considering the mean square error (MSE) in 1,000 simulation studies in each caseof the known parameters and conditions. The results show that the proposed working calibration techniques that can performadequately well are the probit, logistic, and logit calibration procedures. Both the probit calibration procedure and the probitmodel are superior to the logistic and logit calibrations due to the smallest MSE. Furthermore, the probit model-parameterestimates also improve the effects of the misclassification explanatory variable. Only the complementary log-log model andits calibration technique are appropriate when measurement error is moderate and sample size is high.

Abstract: Coronary bypass graft surgery (CABG) is a revascularization procedure which reduces myocardial ischemia and cardiovascular morbidity and mortality in selected patients;however, up to 40% of saphanous vein grafts may degenerate over 10 years. Although coronary angiography is the gold standard to detect graft patency and native vessel disease, sometimes it is difficult to locate the grafts resulting in increased exposure to radiation and contrast administration. This case highlights the utility of cardiac computerized tomography and magnetic resonance imaging to provide comprehensive noninvasive assessment in a patient post CABG.(J Geriatr Cardiol 2007;4:244-247.)

Abstract: The study aimed to develop a waste management training model for the administrators in the subdistrict administration organization in Nongkhai province. The purposive sample of 54 participants participated in the study. The research instrument was developed including two parts; waste management training model and survey questionnaire on opinion about waste management model. The data were analyzed by a percentage, a mean and a standard deviation. The major findings revealed that the developed waste management training model included 6 steps: analysis of the need of participants, specification of objectives, design of training, development of the model, conducting training and evaluation. The model was then given to the experts for validation. These experts reviewed and evaluated the model at the most appropriate level and it had an efficiency at 86.50/88.00. Most of the administrators in the subdistrict administration organizations reported that the training could increase knowledge about waste management from a moderate level to a high level as same as benefits for family units and communities. The steps of training program were appropriated.
