Analysis of steel industries in thailand : Case study of production planning and control by determination of time limited free back orders.
The objectives of this research were to find the distribution of food demand for laying hens and to find the optimum amount of that food production which had minimum cost. The data consisted of customer purchase orders for the food of laying hens price of food for laying hens cost per unit for the food inventory cost related to food of laying hens in which the food was out of stock such as fine overtime urgent purchase for material. They were collected in 2008-2009 form a factory in Nakhonratchasima province. The collected data were analized in order to explore the distribution of the monthly food demand for the laying hens and to see the rate of inventory per unit. The results were used in the stochastic linear programming model for aggregate planning in which the optimum production minimum cost could be obtained. Programming algorithm in MATLAB and tools in Linprog software were used to get the solution. The distribution of the food demand for laying hens and the random numbers were used in the model. The study found that the distribution of food demand for laying hens every month has normal distribution (January to December). The monthly average amount of production from January to December were 10936.94 12913.74 11898.12 13096 15443.26 14916.33 10322.64 10818.21 11393.11 11700.72 9706.05 and 11702.05 respectively. The minimum total cost average for 12months was Baht 62422386.98.

Chemicals management of chemistry laboratories in thailand's higher educational institutions.
The purposes of this research were to study of chemicals management problems in Thailand s higher educational Institutions. It also focused on comparing of problems level of teachers who were different in sex age educational level Institutions and chemistry teaching experience. The sample of this research was 205 chemistry teachers in the Department of Chemistry Faculty of Science from 14 Institutions in Bangkok and in related other areas in Thailand s Higher Educational Institutions. The instruments used in this research were the questionnaire of 5-rated rating scales of those 4 categories. The reliability of the questionnaire was that the storage of chemicals 0.80 the using of chemicals 0.75 the disposal chemicals 0.84 the chemicals hazardous prevention 0.79 with the total average of 0.82. The data were analyzed by Statistical Package for the Social Science for Windows(SPSS for windows). The statistic used was mean standard deviation Hest one-way ANOVA and Tukey HSD of Multiple Comparison Test. The results of the research were: 1. The chemistry teachers had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value at the medium level. 2. The chemistry teachers with differences in sex had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value of non-significant differences. 3. The chemistry teachers with differences in age had the problems of those 4 categories of chemicals management of chemistry laboratories as well as the overall average value of significant differences. 4. The chemistry teachers with differences in educational level had the problems level of the overall average value of significant differences in master educational level with doctoral and post doctoral educational level. 5. The chemistry teachers with differences in Institutions had the problems level of the overall average value of significant differences in old Institutions with Kingmongkok Rajabhat and Rajamangala Universites. 6. The chemistry teachers with differences in chemistry teaching experience had the problems level of the overall average value of significant differences in less than 5 year 5-10 year and.more than 10 year.
Species diversity and reproductive phenology of Podostemaceae in Na Hahaeo District, Loei Province, Northeastern Thailand.
The species composition of Podostemaceae was studied in Loei northeastern Thailand from November 2009 to July 2010 by extensive surveying in the rapids and waterfalls inside and outside of national parks wildlife sanctuaries and protected areas. The samples collected are classified into 2 subfamilies which are Tristichoideae and Podostemoideae. The former contains 2 genera and 3 species Dalzellia kailarsenii Terniopsis sp. 1 Terniopsis sp. 2. The latter has 4 genera and 9 species Hanseniella heterophylla Hydrobryum japonicum Hydrobryum loeicum Hydrobryum tardhuangense Hydrobryum vientianense Hydrobryum sp. 1 Hydrobryum sp. 2 Polypleurum sessile Thawatchaia trilobata. The highest number of species occurs in Hydrobryum with 6 species following by Terniopsis with 2 species. The other four genera have one species each. Based on morphological and molecular analyses revealed that 2 species of the genus Hydrobryum are new and 2 taxa of Terniopsis are also new species. Polypleurum sessile and Thawatchaia trilobata are new recorded in Loei province. The result from this study indicates that the genus richness is relatively high in Loei province which encompasses 60% of the total number of genera (10) in Thailand. The plants in vegetative phase are completely submersed in swiftly running water during a warm wet season (May-October). The plants flower and set fruits and seeds when exposing to air during water level drop in a cool dry season (November- February).
