In order to elucidate the floral ontogeny of certain Thai species of the subfamily Podostemoideae the flowering shoots of Hanseniella heterophy/la Hydrobryum loeicum and Hy. tardhuangense were observed using scanning electron microscope. In all species studied. the flowering shoots protrude from the cavities where the tufted leaves arise on the crustose root. Mostly the two outer bracts are leaf-like interpreting that the flowering shoots are converted from the vegetative shoots. In Hanseniel/a bracts in the early developmental stage are similar shapes but different sizes arranging in 4 rows. In the mid-stage the ventral bracts differentiate into normally 2 lobes occasionally 3 lobes whereas the dorsal bracts develop into long deltoid shape. In Hydrobryum the arrangement of bracts is distichous. The spathellas in all species initiate from tissue surrounding the floral meristem. Prior to the fusion of ventral and dorsal apical margins the spathella apices become a triangle space in Hanseniella narrow long space in Hy. loeicum and two-lipped in Hy. tardhuangense; and the floral organs are initiated inside the spathella. The two tepal primordia the primary androecial primordium and the gynoecial primordium are initiated simultaneously. The two stamen primordia are differentiated from the primary androcial primordium when the gynoecium changes into a cylindrical shape and two carpel primordia are initiated. These dramatic ontogenetic changes and heterochronic shifts in the initiation of floral organs are highly specialized and very distinct floral development which have not found in any families of flowering plants.

The purpose of this study was to evaluate the subject of Statistical Analysis in Business(02-311-133) in the curriculum of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon. The following aspects were studied : the appropriate objective outline content of the curriculum methods of teaching and learning instructors students teaching aids materials classrooms evaluations of the curriculum and achievements of the students who had studied this subject. The sampling group of this study was comprised of 6 instructors who taught a course in Statistical Analysis in Business 324 students who had studied the course and 76 students who had graduated. The research tools were a questionnaire and an interview. The statistics used in data analysis were percentage arithmetic mean (X) and standard deviation (SD.). The Results ofthe study were that 33.33 % of the instructors had experiences in teaching more than 10 years but had conducted fewer researches; the objective outline and content of the curriculum were appropriate and applicable; the teaching aids did not work properly because of no good maintenance; in teaching and learning no activities and fewer group works were assigned to students to practice; the evaluations of the curriculum should not have various forms; there were less of students achievements in synthesizing problems and applying their knowledge to solve problems.

The study noise pollutions at Wongsawang intersection and Rama VII intersection. According Pollution Control Department (PCD) methods. General sound level measurement used for this research and calculate the Leq24br Using the 5-day measurement period. For the result. The Sound level at Wongsawang intersection were exceeding the standard 70 dBA every day. The peak of Leq24br was 80.9 dBA. According the result of PCD. The Sound level at Rama VII intersection were exceeding 2days. Traffic density was a factor that affects the sound level. In addition the maximum sound level (Lmax) of all the measurements were not exceed 115 dBA

The purpose of this study was to study and compare spending behavior of undergraduate of Rajamangala University of Technology Phra Nakhon in 4 aspects : the food expense transportation expense health care expense and entertainment expense. The undergraduates were classified by gender academic years faculties income income source extra income and extra income source. The samples in this research were 432 undergraduates. The study participates selected by stratified random sampling. The 48 item questionnaires of rating scales was used as the research instrument. Percentage mean. standard deviation. t -test for independent sample F -test and LSD analysis were statistical method to analyze data. The results were as follows: 1. The undergraduates Spending Behavior all aspects were in moderate levels that the food expense was the highest health care expense and transportation expense was the lowest. 2. There was Significant difference for undergraduates spending behavior in health care expense entertainment expense and all aspects at the 0.05 level among students in different gender and academic years. 3. There was significant difference for undergraduates spending behavior in food expense health care expense entertainment expense and all aspects at the 0.05 level among students in different faculty. 4. There was Significant difference for undergraduates spending behavior in food expense and all aspects at the 0.05 level am<;mg students in different income and extra income. There was significant difference for undergraduates spending behavior in food expense transportation expense entertainment expense and all aspects at the 0.05 level among students in different income and extra income.

The Purposes of1bis Research were to study of Bachelor of Science Programs in Applied Chemistry and in related other areas in Thailand s Higher Educational Institutions. The sample consisted of 27 Programs of Bachelor ofScience Programs in chemistry Applied Chemistry and Industrial chemistry in Thailand s Higher Educational Institutions. Instruments used for collecting data were Curriculum Data Sheets. The data were analyzed by using SPSS for window. The statistics used were frequency percentage and mean. The results were as follows: 1. Most of the Bachelor of Science programs are chemistry. The others are Applied Chemistry and Industrial chemistry respectively. 2. The Total Course Credits of Bachelor of Science Programs were 137.12 Credits including General Education Courses (34.46 credits) Specific Courses (96.50 credits) and free elective courses (6.42 credits). 3. The Total Course Credits of the Bachelor of Science Programs before 2005 were 140.67 credits including General Education Courses (35.28 credits) specific courses (99.22 credits) and free elective courses (6.61 credits). 4. The Total Course Credits of the Bachelor of Science Programs s after 2005 were 129.13 credits including General education courses (32.63 credits) specific courses (90.38 credits) and free elective courses (8.76 credits). 5. The Total Course Credits of Bachelor of Science Programs in Applied Chemistry were . 130.67 credit including General education courses (37.67 credits) specific courses (85.00 credits) and free elective courses (8.00 credits). 6. The minors of Bachelor of Science programs in Applied Chemistry consisted of Industrial Chemistry and Management Environmental Chemistry Material Chemistry Natural Products Chemistry Polymer Chemistry Applied Chemistry for Industry Chemistry Education and Medicinal Biochemistry.
