    (Journal of Science and Technology Mahasarakham University - วารสารวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยมหาสารคาม, 2011-01-24) Wimonrat Trakarnpruk
    Bimetallic (Pt or Pd and Ga) catalysts were prepared by consecutive impregnation on mordenite. The catalyst wasfurther impregnated with potassium (K) to reduce its acidity. The catalysts were characterized by X-ray diffraction(XRD), nitrogen adsorption (BET) and ammonia temperature programmed desorption (NH3-TPD). The catalyticactivity of the bimetallic catalysts was compared with the monometallic catalysts in conversion of n-hexane. A highercatalytic activity was obtained for Pt catalyst in comparison with Pd sample under the same reaction condition:catalyst 1 g, weight hourly space velocity (WHSV) of 1, 1 h time on stream and reaction temperature at 400°C. Theresults indicate that Ga incorporation changes the product selectivity, selectivity towards dehydrogenation products  was increased but selectivity towards isomerization products was decreased. The catalyst with K addition, 0.5 Pt/1Ga/3% K/M exhibits enhanced selectivity to aromatics (9.5%) which is due to decreased acidity of the catalyst.

    The objectives of this participatory action research include the building of policy on public health where the work focused on the issue of an alcoholic free community. The work was carried out through the participatory actions of people in the community. The work was conducted within the Thasongkhon Healthy Civil Society network of Maha Sarakham Province. Numbers of representatives of thirteen villages were used. Data collection was carried out through group interviews, observations and note taking. The study was divided into three major phases, i.e., with Phase I: The establishment of village leadership. This phase focused on the recruiting of a research team, network build up, choosing leader and set out the implementation guidelines. For Phase II, this phase includes the setting out of operation plans. There were five steps to be carried out within this phase, i.e. (1) building up leadership. (2) Operation plans, (3) develop potential leaders of the health assembly in villages, (4) organizing small units of health assembly in the villages. (5) Organizing macro scale units on health assembly. With Phase III, this phase includes the overall assessment of the three phases of the program. Analysis of the results included the qualitative data, content analysis and health assembly process.The results showed that the implementation of the program established a concrete organization of the village of Thasongkhon Healthy Civil Society where there were 32 members as stakeholders who are the representatives of the village, local and government organizations. The program was able to establish village key men of the Health Assembly Network of 163 persons. The development program for use in training potential village key men of Health Assembly Network led to the application of healthy public policy, particularly on the issue relating to community having no alcohol through the campaigning within the 3 phases of small health assembly. The output of the program was a healthy public policy at both village and zone levels. The summary of the results could be used as a policy in applying to a larger health assembly unit. The results of healthy public policy focusing on the Issue of alcoholic free community with the participation of people based on democratic participations led to 10 policy proposals where the establishment could build up unanimity, unity and firmness among people in the community. The results could encourage every village to apply this healthy public policy for their community at least at the family level where a Healthy Assembly Network key men could assist villagers in better communities.

    Feasibility Study on Producing Physic Nut Oil for Diesel Oil Substitution in the Sriprachan Community, Suphan Buri Province
    (Journal of Science and Technology Mahasarakham University - วารสารวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยมหาสารคาม, 2010-03-02) Surat Silsorn; Suwanna Praneetvatakul
    The objectives of this study were to study the suitable land management techniques required to cultivate physic nut in order to substitute diesel oil in agricultural engines and do an economic analysis of 20 physic nut oil producers. Some secondary data were obtained from research project under Kasetsart University Research and Development Institute. Data were analysed using net present values (NPV), benefit cost ratio (BCR) and internal rate of return (IRR). The results of the study showed that most rice farmers used vacant land to cultivate physic nuts at 1.34 rai/household. The total demand of community diesel oil for an agricultural engine was 2,968,416 liters per years, but physic nut oil production in the community met only 0.032 percent of total demand. Project economic analysis of physic nut oil production in a period of 10 years and with a discount rate of 5 percent, revealed that it was not worth when NPV is -1,083,059.13, BCR is 0.38 and IRR is not applicable. The project sensitivity analysis also revealed that the project would have economic worth if they had produced 20 percent of seedlings on sale. This study identified three causes of low feasibility in physic nut oil production for diesel oil substitution in agriculture. They were 1) economic factors 2) land use factor and 3) physic nut yield factor.

    This quasi-experimental research aimed to evaluate sexual attitude, self perception of sexual behavior and effectiveness learning process of students who enrolled and studied in sex-education and family life preparation course (SFLP) in Mahasarakham University. The student samples were simple random sampling and divided into two groups such as experiment group (100 students) and control group (100 students) and the learning method in experimental group was integrative teaching with student center orientation while conventional teaching orientation in controlled group. The data were collected by using questionnaire and observing. The percentage, mean, standard deviation, independent sample t-test and pair sample t-test were applied for statistic used.Results found that: both experimental groups and control group are similar in sex and the average age of 19 years. Most of them who enrolled in SFLP achievement learning (GPAX) are moderate level (experimental group 63.0%, and control group 74%). The average difference achievement learning score after intervention found a statistical significant difference (p \< 0.001). Most of students have self perception on attitude, such as a female should remain a virgin until her wedding (experimental group 57.0% and control group 62.0%), sexual relationship during adolescence lead to parent’s disappointment (experimental group 57.0% and control group 61.0%), and better sexual relationship occurs when older than this (experimental group 42.0% and control group 44.0%). The sexual nude book is interesting (experimental group 42.0% and control group 44.0%), sexual arousal (experimental group 28.0% and control group 26.0%) and imitation were initialized by male adolescence and sexual intercourse decision (experimental group 25.0% and control group 23.0%). The perception for sexual behavior both male (73.4%) and female (75.0%) agree with their parents are the major role model for sexual adolescence explicit behavior such as having lover partnership (female 64.1%, male 62.5%) be normally behavior and get more opportunity for sexual behavior with other at entertainment and internet places (female 54.7%, male 38.8%). Loving couple should have sexual intercourse on Valentine’s Day (female 34.4%, male 19.4% ) and also be homosexual (female 60.1%, male 38.9%). The attitude level of students for teaching in this subject found that: the student center learning method let them open opportunity for more discussion (level good in experimental group 39% and control group 38%) and share experience about sexual theme. The appropriate sexual media (level good in experimental group 50% control group 26%) had mutual inclusion on sexual context and linkage knowledge and experience or virtual experience and student can get more skill on human sex (level good in experimental group 36% control group 37%).The conclusion of the student center learning method management in SFLP gives more learning participatory, knowledge and attitude also right sexual skill perception.

    The purpose of this research was to study the effectiveness of village health volunteers in Muang district Mahasarakham province making visits to the homes of diabetes mellitus patients. Participatory action research was used. The subjects were 45 diabetes mellitus patients and 15 village health volunteers. The tools used for the research consisted of forms for testing diabetic knowledge, questionnaires about the self care behavior of diabetes mellitus patients, and the log book of the village health volunteers. The procedures of the research were: 1) selecting village health volunteers for set training 2) selecting diabetes mellitus patients and pretesting their knowledge and selfcare behavior 3) home visits by village health volunteers every 2 weeks for 3 months 4) posttest about knowledge and selfcare behavior after the home visit program, and then compare pretest and posttest results 5) compare fasting blood sugar before and during the program 6) interviews and recommendations from village health volunteers and diabetes mellitus patients about the activities they thought were the most useful and the most troublesome. The findings of the research were as follows: average scores of knowledge about diabetes mellitus of village health volunteers after attending the class had increased significant statistically (p-value=0.005). Average scores of knowledge about diabetes mellitus and self-care behavior in diabetes mellitus patients increased. Average scores of knowledge about diabetes increased significantly statistically (p-value=0.000). Average scores of self care behavior of diabetes mellitus patients after attending the program had increased but not significantly statistically (p value=0.035).Average of fasting from blood sugar during the program(166.04 mg/dl) decreased compared with before the program (198.04 mg/dl). Improved self-care behavior and decreased fasting of blood sugar may decrease complications from diabetes mellitus. Interviews with village health volunteers and diabetes mellitus patients show that both are satisfied with this program and suggested it be continued and expanded.

    The objectives of this study were to compare before and after pharmaceutical care in patient’s INR, knowledge scores about disease, warfarin treatment and correction of self-management while using warfarin, number and type of warfarin-related problems. Patients who were treated with warfarin and got service in the anticoagulation clinic at Roi-Et Hospital during January 9 to April 12, 2006 were recruited. This study was a before and after experimental study with no control group. Primarily, 60 patients were included but one was excluded because of irregular attendance at treatment follow up. Among 59 patients, 39 were women (66.1%) and 20 were men (33.9%). Their average age was 51.1 ± 10.7 years old. Most patients either before or after pharmaceutical care had INR lower than the target INR (69.5% and 47.5%, respectively). The number of patients who had INR lower than the target INR was significantly decreased than before pharmaceutical care (p \< 0.001). The average knowledge scores about disease, warfarin treatment and correction of self-management while using warfarin before and after pharmaceutical care were 6.58 ± 1.62 and 9.80 ± 1.30, respectively. There was a significant increase in the average score after pharmaceutical care (p \< 0.001). Warfarin-related problems before pharmaceutical care were 70 in 43 patients (72.9%). The most common types of problem were non-compliance (27.2%), subtherapeutic dosage (25.7%), and bleeding (21.4%). After pharmaceutical care, there were 20 problems in 16 patients (27.1%). The type of these problems included subtherapeutic dosage (35.0%), drug-drug interaction (35.0%), and bleeding (30.0%). The number of warfarin-related problems was significantly decreased after pharmaceutical care (p \< 0.001). Therefore, the drug counseling and pharmaceutical care by pharmacists for patient who used medication could help reduce drug-related problems, increase knowledge, understand warfarin therapy and correct self-management that would lead to increase the effectiveness of therapy and patients’ quality of life.

    Activation Process for Cementitinous Materials
    (Journal of Science and Technology Mahasarakham University - วารสารวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยมหาสารคาม, 2010-03-31) Nipon Tanpaiboonkul
    Pozzolanic reaction is a reaction of pozzolanic material, which could be used as an additional material to Portland cement. Pozzolan is a siliceous and aluminous material (available in fly ash, rice husk ash and etc.), which reacts with calcium hydroxide and water to form calcium silicate hydrate (CSH) compounds like a cementitinous material but it is slowly reacted. The activation processes such as mechanical by grinding, thermal and chemical process can resolve this problem to increase the strength development in early age. Several research works have been conducted on the use of chemical process to improve the performance of cementitinous material because it is convenient to prepare specimens. Furthermore, it increases pH in a mixture and also the rate of a reaction could be increased. Therefore, the uses of activation processes for cementitinous materials are applicable for construction works or hazardous waste management.

    Halophilic Bacteria Potential for Development of Thai Fish Sauce Industry
    (Journal of Science and Technology Mahasarakham University - วารสารวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยมหาสารคาม, 2011-01-24) Sirilak Namwong
    Thai fish sauce, a traditional seasoning with salty flavor and mild fishy smell, is a clear brown liquid derived from fish fermented with salt in natural conditions for 12-18 months. During the fish sauce fermentation process,proteinase-producing halophilic bacteria were isolated and their proteinases were characterized, in order to speed up the degradation of fish protein during fermentation. Recently, acceleration of fish sauce fermentation was investigated using the combination of halophilic bacteria as a starter culture and commercial proteinases. The fermentation process was completed within 4 months and the fermented product comprised of overall sensory characteristics of traditional fish sauce. Therefore, the acceleration of fish sauce fermentation may expand the growth of the fish sauce industry that is limited by high capital investment of land and extremely long fermentation time, and increase the export of Thai fish sauce worldwide.

    (Journal of Science and Technology Mahasarakham University - วารสารวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยมหาสารคาม, 2011-01-25) Parkorn Suwanich
    Rock salt samples of drill core from potash exploration boreholes by the Department of Mineral Resources were analyzed for potassium bromide (KBr) content. The potassium bromide contents in the rock salt members have revealed the origin and the deformation of the rock salt in the past. The concentration of potassium bromide in rock salt members were plotted with depth. In addition, the profile of KBr content also indicated the tendensy of potash  deposition indicated by a high corespondent with sea water concentration which eventually reached the potash deposit condition. The potash zone has overlain the lower salt member and can be found in both the Sakhon Nakhon and Korat basins. The rock salt strata in the Maha Sarakham formation in NE Thailand has three members, upper, middle and lower salt members. Generally, the potassium bromide content in the upper salt ranges from about 200 to 300 ppm, whereas the middle salt starts at about 200 ppm and increases rapidly to 500 ppm. In the lower salt, the potassium bromide content starts from about 100 ppm and keeps this rhythm until it reaches the potash bed above. After that it increases dramitcally to 500 ppm. However, the lower salt, which formed very high domes and diapirs, also shows the potassium bromide content along a very deep section at a level of about 100 ppm.

In total, 5, 607 individuals were found, belonging to 15 species. Nine species were found in the highest species diversity plots, which were in a dry evergreen forest in a valley and stream valley or water fall plots. Three species were found in the lowest species diversity plots, which were grass land on a table top plain plot. The highest abundance plot was in a dry dipterocarp forest on a hill slope,which yielded 1.48 individuals/m2. The lowest abundance plots were grass lands on a table top plain, which yielded 0.02 individuals/m2. Species diversity indices (H) ranged from 0.284-1.681 and the dominant species indices (C)ranged from 0.220-0.877. The highest species diversity index was the plot, which showed the lowest dominant species index. It was in the dry evergreen forest plot in the valley. Whereas, the lowest species diversity index and highest dominant species index plot was the grass land plot on the table top plain. The Sorensen’s similarity coefficient (Ss) of land snail species in each forest type ranged from 0.526 to 0.923. The lowest Ss was between the dry evergreen forest and the grass land plots, whereas the highest Ss was Ss between the dry dipterocarp forest and the forest garden. The most abundant species was Cryptozona siamensis; 2,235 individuals (39.86%) were collected.Hemiplecta distincta was found in all plots. Cyclophorus sp., Sarika sp., and Chloritis tenella were found only in a few plots of dry evergreen forest in the valley. Streptaxid was found in two plots of dry evergreen forest in the stream valley and water fall area. Amphidromus (Amphidromus) schomburgki schomburgki was found in abundance in most dry evergreen forest plots in the valley and stream valley and water fall area. This population is the highest abundance among reported population in Thailand and composed of nearly a similar ratio of dextral and sinistral shells.

    The objective of this study was to determine the result derived from prescribed drug related problem (DRPs) solving among elderly diabetic patients being observed by home visits carried out by a pharmacist. The design being used for this study was a one-group pretest-posttest experimental study and it was applied to 21 elderly diabetic patients. The results showed that nineteen DRPs were found with 11 patients during the first home visit. Number of DRPs gradually decreased during the second and third home visits. The most common DRPs found were related to the failure to receive medication (42.10%). Mean numbers of DRPs per patient in each pair of home visit were also compared by paired t-test. It was found that mean numbers of DRPs per patient were statistically significant for the first (mean = 0.90± 1.04) and second home visits (mean = 0.33± 0.48). However, they were not significantly found between the first and third visits and also between second and third visits. Therefore, home visits by a pharmacist provided high beneficial effect in elderly diabetic patients.

    The purpose of this research was to study the effects of colchicine concentration and treated duration time on growthand chromosome number inDendrobium draconis Rchb.f.. The protocorm of Dendrobium draconis Rchb.f. after onemonth germination was treated with 0.05 %, 0.10 % and 0.50 % (w/v) colchicine for 4 and 5 days. The protocormswere then cultured in VW medium for 14 weeks. Growth and chromosome number from root tips were examined.Height and leaf number of the control and colchicine treatment groups were not significantly different but stems of thecolchicine treatment groups were bigger than those of the control group. Moreover the leaves were greener than thecontrol group. The thickness and length of the stomata, and the thickness of leaf directly related to the colchicine concentration. The chromosome number from root-tips of the control group and the treatment groups with colchicineconcentration 0.05% were 2n=2x=38 while the chromosome number of treatment groups with colchicine concentration0.10% and 0.50 % (w/v) for 4 and 5 days were 2n=4x=76. The level of ploidyDendrobium draconis Rchb.f. wasconfirmed by flow cytometer. The results indicate that treatment of protocorms with 0.10 % (w/v) colchicine for 4 dayswas suitable to induce polyploidy in Dendrobium draconis Rchb. f..
