The purposes of this research were 1) to study perception and retention production placement in Ban Nee Me Ruk situation comedy (sitcom) 2) to compare demographic characteristics purchasing decision behavior and 3) to study correlation of perception and retention production placement in Ban Nee Me Ruk Sitcom which purchasing decision behavior. The data were collected from 420 residents in Bangkok Metroplitan who were watching Ban Nee Me Ruk Sitcom. Data analysis employed frequency percentage arithmetic mean () and standard deviation (SD.) Statistics used for hypothesis testing included t-test One-way ANOVA and Chi-square. The study presented the following results: The presentation of the production placement included: display product images impulse buying shelves that attract customers. Another character of retention in the production placement was the latent contents. The production display were convenient goods such as Mamy Poko and Lactasoy. After the residents samples watched Ban Nee Me Ruk Sitcom the purchasing decision behavior was in the middle level (52.1%).

The purposes of this study were to compare the learning achievement retention and preference of students in teaching with games and the conventional teaching in reading the first-angle projection the third-angle projection isometric picture and auxiliary view according to the first-year diploma curriculum. Students were devided in to two groups: the experimental and the control group. The research instruments were the sets of games models transparencies achievement and retention test and the preference guestionnaires develop ped by the researcher The t-test was used to find the mean score difference. The findings were : 1) the learning achievement in learning with games was higher than that of the conventional teaching at .05 level of significance 2) the learning retention in teaching with games was higher than that of the traditional teaching at .05 3) the learning preference in teaching with games was higher than that of the conventional teaching at .05 level of significance.

The research was to develop environmental packaging from composite materials hyacinth fiber rice husk and coconut fiber for temperature preservation to replace the use of foam packaging that cannot be degraded naturally. In the composite materials water hyacinth fiber rice husk and coconut fiber at the ratios 7: 1: 2 1 : 1 : 2 and 1: 1: 1 were extruded by heat using isocyanate glue as a solder and testing the physical and biological properties of composite materials as fiberboard. For testing of temperature preservation of the bio packaging heat transfer test to obtain the bio-packaging for the environment the composite materials of fiber water hyacinth rice husk and coconut fiber at the ratio of 7 : 1 : 2 was the most appropriate type. Since it had a density of 0.7 grams per cubic centimeter strength of 26.76 MPa moisture content of 3.8 percent ages and swelling of 26.63 percent ages. In dry condition at room temperature it could store heat for 2 hours and could retain the cold temperature as shown for the temperatures rising from 4 to 30.7 degree Celsius within 2 hours. This research therefore presents a new alternative method of natural fiber composite materials application for temperature preservation in order to reduce the use of foam containers and increase cost value to natural bio waste materials.
