This thesis emphasizes the improvement approaches of quality on digital data to be more sharpness by two- dimensional technique. Today the availability from the improvement of Digital Image Processing is used widely in various occupations such as medical field with reading the results from CT scanning military field with the improvement of aerial map for country prevention agricultural field with leaf analysis of its disease and the educational field with the image processing and robot vision to increase its effective learning and remembering development. It can be seen that the image development through its sharpness is really crucial therefore this thesis used the Gray Scale for transforming by two-dimensional wavelet and LL Band got from this wavelet transform to be improved by histogram technique. The histogram was divided into 4 parts based on its cumulative density at 0.25 0.5 0.75 and 1 then smoothed the data by separation after that brought the results to invert wavelet which gives the new image through improved LL band. The research result revealed that the mean of the Absolute Mean Brightness Error (AMBE) was decreased while enable the image sharpness to suitably increase 80%.

The study of the amount of the use of Wolffia Substitute for Pandanus in Thai Lod Chong dessert. The objectives of Lod chong desert Project is to study basic reeipes and The use of Wolffia Substitute for Pandanus in Thai Lod chong dessert. Used to the amount wolffia in a different 4 levels : 0% 50% 75% and 100% of the pandanus weight. The experiment is analyzed by Randomized Complete Block Design (RCBD) to evaluate the sensory quality of appearance color flavor taste texture (stickysoft) and overall preference. The sensory evaluation is scored in 9-Point Hedonic scale. There are 80 participants including teachers and third year students from foods and nutrition field who are not trained on food tasting the Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The study is analyzed by analysis of variance (ANOVA) and Duncan’s New Multiple Range Test (DMRT). Statistical evaluation is also used to analyze. The study finding showed that accept amount of the use of Wolffia for Pandanus in Thai Lod Chong dessert at 100% highest every aspect. The average 8.43 8.21 8.16 8.24 8.33 and 8.34 which was in much. When is analyzed by analysis of varianece and to compare different with statistical significant. Finding showed that the appearance color flavor taste texture (stickysoft) and overall were different with statistical significant (p≤0.05).

This study aims to examine meanings and compare emotional words appeared in entertainment magazines. The study was carried out by synthesizing the content according to a definition framework on the meanings of emotional words by Rungthiwa Chatthanrasmi. That can be classified into 3 categories; emotional words expressing emotions and feelings of the speakers emotional words expressing desire and demand of the speakers and emotional words expressing perception and thought of the speakers. Data collected from movie magazines issued 914 year 9 Bang Ra Chan and issued 998 year 9 Wi Marn Mek Khala. The results found that there were 9 emotional words in Bang Ra Chan that expressed the speakers’ feelings; the emotions of dissatisfied surprised suspicious or inquiring loving frightened pitying annoying insulting and indignant. The results showed 18 emotional words in Wi Marn Mek Khala; frightened sarcastic surprised excited disliked dissatisfied suspicious or inquiring annoying blundering appreciated delightful discouraged indignant pitying distressed teasing being at ease and feeling sorry for the loss. Moreover there were the same emotional words appeared in both Bang Ra Chan and in Wi Marn Mek Khala expressing more than one meanings for example “Tho!!” (pitying annoying and frightened). There were also the emotional words used to express desire and demand of the speakers in Bang Ra Chan and Wi Marn Mek Khala that divided into 3 aspects. The first one was the word “Aow” in Bang Ra Chan and the word “Hei” in Wi Marn Mek Khala. The second one was the words that expressed getting attention the word “Hei” in Bang Ra Chan and the words “Chuay Duay” “Ah Ham” “Hei” in Wi Marn Mek Khala. The third one was the words expressing argument of the speakers as the followings “Aao” in Bang Ra Chan the words “Wei” “Aoi” “Hei” in Wi Marn Mek Khala. Also there were the same emotional words appeared in both Bang Ra Chan and in Wi Marn Mek Khala that conveyed more than one meanings on desire or demand of the speakers for example “Hei” expressing desire or demand getting attention and argument of the speakers. There were the same use and different use of the emotional words that expressed perception or thought of the speakers. The word that expressed the speakers’ perception in Bang Ra Chan was “Er”. The words that expressed the speakers’ perception in Wi Marn Mek Khala were “Aor” “Hm” “Um” “Er”. They both used the same emotional words “Er”.

The objects of this research were (1) to study Third-Year Students’ stress at Faculty of Business Administration Rajamangala University of Technology Phra Nakhon. In Overall and each of four aspects: learning management study skills learning environment and relationship with classmate. (2) To compare stress of Third – Year Students Stress at Faculty of Business Administration. In overall and each aspect classified by gender major group grade point average (GPA) place of birth family economic status the inter personal relationship between student and parents child. The simple consisted of 439 Third – Year Students Stress at Faculty of Business Administration. The statistics used for analysis the data were frequency percentage mean standard deviation t-test one way analysis of variance and LSD. The result of the study revealed that: 1. Male and female students had significant different of stress on relationship with friends at .05 level. 2. Students with different major group had significant different on overall stress at .05 level. 3. Students with different grade point average (GPA) had significant different of stress on relationship with friends at .05 level. 4. Students with different family economic status had no different of stress. 5. Students with different place of birth had no different of stress. 6. Students with different interpersonal relationship patterns had no different of stress. 7. Students whose parents had different child rearing styles had different stress in learning management study skills and learning environment significant at .05 level.

This research studied the factors that affect the efficiency of phosphate reduction in the wastewater of the washing process with CaCO3 and CaO produced from eggshell and mussel shell. The study found that the optimum condition for adsorption when using CaCO3 from eggshell is to adjust the pH to be equal to 10 take 15 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing the adsorbent to CaO the optimum condition for phosphate removal is to adjust the pH to 7 take 15 minutes to absorb and add 1 gram of adsorbent which can reduce the phosphate content by 24 percent. The optimum conditions for adsorption when using CaCO3 from mussel shell were to adjust the pH to 10 take 45 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing adsorbents to CaO the optimum condition for phosphate removal is to adjust the pH to 10 take 15 minutes to absorb and add 3 grams of adsorbents which can reduce the phosphate content by 24 percent. In addition when studying the adsorption of impurities in the wastewater such as conductivity turbidity COD and BOD it is found that the optimum reduction conditions can reduce the impurities of the parameters that mentioned above were 19.32 2.60 54.77 and 16.67 percent respectively. CaCO3 and CaO produced from eggshell and mussel shell can be used to absorb impurities in wastewater before releasing into natural water sources.
