Deterioration of reinforced concrete deep beam structure caused by chloride is severe andtakes up wide area even though the structure is not exposed to sea water or brackish water. Even the structure which is far from sea water or brackish water is affected by this problem.When the reinforced concreate deep beam structure is affected by chloride steel reinforced inside the structure is corroded resulting in reducing the cross-sectional area of the reinforced steel affecting load capacity deflection and beam failure. If there is no repair or strengthening such capabilities are continuously reduced until it is no longer safe to use the beam. Therefore it is necessary to repair or strengthening the deteriorated structure to be safely used. This research investigated strengthening of deteriorated reinforced concrete deep beam caused by chloride with 4 formats of carbon Fiber sheets to seek guidelines for the most efficient strengthening. The resultshowed that the strengthening by the 4 format of carbon fiber sheet could increase ultimate loadcapability yet could not improve ductility of the deteriorated beam to become close to the beamthat is not deteriorated. The strengthening that could increase the maximum ultimate load capability was the table format strengthening. In addition the strengthening that the carbon fiber making 45 degrees with the length of the beam could best prevent diagonal cracks.

Dyes contaminated in wastewater that negatively affecting the environment and human health. The objectives of this study to prepare activated carbon from Salacca zalacca (Sumalee) seeds activated by 36 mmol/g KOH dye solution and activated carbon ratio 20:32 ml/g for dye removal. The influents of dye removal from wastewater by Salacca zalacca (Sumalee) seeds activated carbon were investigated as initial dye concentration activated carbon and dye solution ratio and contraction time. The moisture content the iodine number the methylene blue index and the functional groups by FTIR technique of the Salacca zalacca (Sumalee) activated carbon were characterized and the kinetics adsorption were also analyzed. The results showed that the activated carbon was the microporous material the highest dye removal from wastewater was 7.50 ± 0.25 mg/g the equilibrium time was 150 min with the activated carbon to dye solution ratio of 1:500 g/ml for 200 mg/l initial concentration. The kinetics of the adsorption process can be described by a pseudo-second order model (R2 = 0.9999). When increasing the initial concentration of dyes the adsorption efficiency was increased. The amount of activated carbon increased resulting in lower adsorption efficiency and the equilibrium time was longer

. This research aimed to study the acidification processes of carving vegetable using acid conditioning machine under emperature and pressure control which was developed in this study. Four acidification procedures were done at normal atmospheric pressure (method 1) under vacuum pressure for 10 (method 2) and 20 min (method 3) and vacuum pressure alternating with normal atmospheric pressure for each of 1 hour. There were two main parts of acid conditioning machine including the temperature controller inside the pickle tank and heat conductor tank and the pressure controller inside the pickle tank. The pickling temperature was stabled at 40oC under the pressure of 0.5 Bar. PLC (Programmable Logic Controller) program was used to write the ladder for controlling all processes and display through SCADA system. The results showed that the acidification method by soaking the carved-rose carrot under vacuum pressure alternating with normal atmospheric pressure showed the shortest time to equilibrium by 7 hours. Then the carved-rose carrot was packed in the glass jar followed by sterilized in boiling water for 15 minutes and stored at room temperature for 7 days. Total bacteria count Escherichia coli and Yeast-mold were not exceeded than the standard limit. Staphylococcus aureus was not detected throughout the storage periods

The objective of this research is to study and find the relationship between Role Perception of conservation Fruits and Vegetable Carving with individual variables including gender educational level and experiences of fruits and vegetable carving Contributing factor including knowledge of fruit and vegetable carving Opinion towards fruit and vegetable carving and participating in fruit and vegetable carvings conservation activities. The research sample were randomly selected 249 of Bachelors degree students of Home Economics Technology Faculty from Rajamangala University of Technology Phra Nakorn Rajamangala University of Technology Krungthep and Rajamangala University of Technology Thanyaburi. The research methods were questionnaires and collected data were analyzed by using descriptive and inferential statistics. The study found that The Role Perception of conservation Fruits and Vegetable Carving is at high level The opinion towards fruit and vegetable carving and participating in fruit and vegetable carvings conservation activities is in relation to The Role Perception of conservation Fruits and Vegetable Carving The Statistically significant were at a level of 0.05. The knowledge of fruit and vegetable carving was not related to The Role Perception of conservation Fruits and Vegetable Carving.

The purpose of this research aimed to 1) study the basic data for the development of specialized professional course on vegetable and fruit carving 2) design and examine the quality of specialized profession course on vegetable and fruit carving 3) try out specialized profession course on vegetable and fruit carving and 4) improve and revise specialized profession course on vegetable and fruit carving. The samples were 3 key respondents and 20 attendees. The instruments included an indepth interview form and evaluation form. The data was analyzed by descriptive and inferential statistics. The findings revealed that the current patterns used for teaching carving (2019) included fruits for consumption perforated leaves grooved leaves closed-carpel roses dahlia zinnia and plumeria for decoration and food works. The most popular kinds of vegetables and fruits for carving were cantaloupes long cucumbers and carrots. The most popular pattern was rose. The duration for vegetable and fruit carving per 1 piece was 5 minutes. The results of course design and quality examination showed the highest IOC (0.82). For course try-out the values of evaluator confidence index came out as follows i.e. RAI of Unit Plan 1 = 0.85 RAI of Unit Plan 2 = 0.94 RAI of Unit Plan 3 = 0.92 RAI of Unit Plan 4 = 0.89 RAI of Unit Plan 5 time 1 = 0.82 and RAI of Unit Plan 5 time 2 = 0.79; implying that skill evaluation action and carvings went in the same direction.
