This Research is to Study the Development of 6k White Gold Alloys for Jewelry Production. The Influence of Admixtures on Mechanical Properties was Investigated (Tensile Strength and Hardness) of 6k White Gold Alloys at Various Composite Ratios. The Results of the Experiments Show that the Chemical Composition of 6k White Gold Alloys is Slightly Different when Compared with the XRF (X-ray Fluorescence Spectrometers). Compare the pre and Post-Melting Quantities. Test results of Mechanical Properties of Test Pieces. The Tensile Strength of the 6k Gold Alloy is 25% Au+46%Ag+8%Cu+3%Zn+18%Pd The Highest Value was 1.14 kN / mm2 the Lowest Percentage was 64% and the Hardness was 259.87HV. The Result of this Test is that the Mechanical Properties of the Material are Brittle Material. When the Mold is Formed the Fracture and Forming will be Difficult. 25%Au+42%Ag+12%Cu+3%Zn+ 18%Pd 25%Au+50%Ag+4%Cu+3%Zn+18%Pd and 25%Au+54%Ag+0%Cu+3%Zn+ 18%Pd Tensile Strength in the Range of 0.66-0.70 kN / mm2 Percentage of Elongation in the Range of 84-90% and Hardness of 277.60 244.60 and 186.73HV Respectively. The Mechanics will Show that the Alloys of White Gold 6k 25%Au+54%Ag+0%Cu+3% Zn+18%Pd Have Similar Tensile Strength. The Maximum Percentage of Elongation is 90% and the Minimum Hardness is 186.73HV. It is Suitable for Forming because it has Ductile Material. This is a Good Mechanical Property in the Metal Forming Machine.

This research presents the engineering properties of asphalt (AC 60/70) modified with different ratios of rib smoked sheet. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 9% rib smoked sheet into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 9% rib smoked sheet. For asphaltic concrete Marshall Stability increased with adding rib smoked sheet into asphalt. Moreover the stiffness modulus of asphaltic concrete can be improved 9.03 compared to AC 60/70.

Study of Natural Dye from Golden Shower Pod for Development of UV Protection on Textile Product aimed to examine natural dyes obtained from Golden Shower Pod to produce naturally dyed fabrics as products. According to the research it was found that cationic additives which were soaked in a ratio of 20 grams per liter and boiled at 100 degrees Celsius for 20 minutes could help enhance the intensity of fabric dyes and the mordant used in this research which was soaked after dying was copper (ll) sulfate at concentration of 10 grams per liter for 30 minutes. According to appropriate tests the value of ultraviolet rays was excellent the dye fastness to artificial sunlight was moderate the abrasion was very good the dye fastness to acidic perspiration was good the dye fastness to alkaline perspiration was less and the dye fastness to water was good. According to the questionnaires returned it was found that the sample was interested in knitted apparel products most demands in the shade were darker tones and the apparel design concept chosen was mini dress with 1960s vintage style by matching dark and light brown of natural dyes of Koon pods. According to the assessment of satisfaction towards the products made from UV-resistant fabrics it was found that the form of products that are suitable to wear everyday was highest (58 percent) the form of the products that are appropriate for women in the age range 20-30 years was highest (66 percent) the arrangement of light - dark dyes of fabrics was highest (42 percent) the appropriateness of colors of embroidery threads was highest (58 percent) the appropriate relationship between patterns colors of embroidery threads and colors of fabrics was highest (76 percent) the appropriate placement of patterns was highest (40 percent) the appropriate size of patterns was highest (48 percent) the appropriate rhythm and continuity of patterns was highest (36 percent) the overall usability of products made from natural dyes that can block ultraviolet radiation was highest (82 percent) the appropriate relationship between embroidery patterns materials and fabrics was highest (12 percent) and the products (apparel) that can be worn at any occasion was highest (52 percent).

The objectives of this study were (1) to find out the Karen weaving in the style of Karen Tapernki Suphan Buri and (2) to study the design and color used for Karen fabric weaving. Interview was the selected instrument to find out the information relating to Karen fabric weaving. The sample was Karen weavers from Tapernki Suphan Buri. The finding illustrated that the popular patterns for weaving were “Chok” and “Kid”. Geometric figure such as “Ne-Oun- Ge” “A-Ku-Sa” “Cher-Tuk-Ke” “Cha-Mi-Ta” and “A-Kor-Tai” were the popular patterns for weaving as well. The color chosen for weaving were both synthetic color and natural color. These were the old patterns inherited by Karen. The research show the result that the sample’s demand was bag made for woman. The pattern of the weaving was inspired by the concept of Art Deco which characterized by spire decorations and furniture. The researcher applied the concept of Art deco with the Karen weaving which characterized by geometric design. By bring the color trend in year 2014 to choose the weaving tone. Dyed fabric in natural color was chosen in order to be proper with Art Deco concept. The evaluation of the sample was satisfy with Karens textile products by Karens Tepernki Suphan Buri were as follows: (1) the design of the product was 65% fitting for Art Deco concept; (2) the design of the products was 57% in vogue; (3) the color design of the products were 60% fitting; (4) the color of the products were47% conform with the color trend of year 2014; (5) woven Karen fabric was 51% fitting for accompanying with PU leather; (6) the strength of woven Karen fabric accompanied with PU leather was 39%;(7) The products was 45% proper for the purposes of using; and (8) the size of the products was 58% proper for storage.

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”.
