This research aimed to study the optimum factors affecting the quality of gold plating process to enhance OTOP knife products of Ban Mai knife forgers village. This study focused on application of AISI 5160 steel and the 24k gold plating process.In the experiment three samples of plating currents were observed; 10 12 and 14 volts each at 30 60 90 120 150 seconds and 180 seconds respectively. The study found that applying the electric currents in gold plating at 12 volts for 120 seconds gave the best results for the gold color and thickness by giving the thickness of the gold surface at 33.82 micron and the color value between L*=88.72 a*=4.45 and b*=78.58. Moreover the gold dispersion was consistent throughout the workpiece. From applying the electric currents in gold plating at 10 volts it lessened the thickness of the gold plating which made the gold plating look uneven. From applying the electric currents in gold plating at 14 volts it increased the thickness of the gold plating which resulted in a dull or burned finish from over-plating. In comparison the cost of the knife before plating with gold costs only 30 baht per piece while the cost of the knife after plating with gold costs 99 baht per piece. In conclusion the daily sales of a product increase from 50-60 items per day to 60-75 items per day which also resulted in increased revenue and profitability from 1500-1800 baht per day to 5940-7425 baht per day on average.

The surveillance and reports on accidents for the current traffic management are carried out by viewing and inspecting CCTV footage. This method is slow to detect incidents and requires a lot of manpower. Since nowadays communication technology and social media play a role in reporting such incidents this research has been conducted to investigate accidents of interest from text messages reported on social media in Thai. There is currently no research or platform that supports this type of work clearly. This research presented the development of a neuron network memory-learning model to solve the problem of incidence pattern classification and incidence severity identification from social media messages in Thai. Using deep learning models such as MLP CNN Bi-LSTM and LSTM+CNN the study was designed and divided into three experimental patterns. This included examining patterns to identify traffic incidents that may be reported as general news or traffic reporting; examining patterns to indicate the type of incidents such as traffic accidents disasters damaged roads or others other than those mentioned; and examining patterns to specify the severity levels of the incidents such as normal intermediate traffic lane blocking or immovable. The experiments demonstrated the capability of CNN+LSTM learning models with the best incidence detection result at 93.44 %. The CNN model gave the best result in identifying a pattern of incidence at 85.29 % and the LSTM model was best able to determine the severity levels of the incidence at 88.53 %.

The objectives of this research were 1) to study the problem of public relations of OTOP products in Bangkok and 2) to formulate a strategy to publicize Bangkok OTOP products. This is a qualitative research; studied from the document and interviews with a total of 5 key informants executives officer in the public relations of OTOP products in Bangkok and operators of OTOP products in Bangkok all 5 product categories The results were as following: 1. The problem of public relations for OTOP products in Bangkok; it was found that there were 11 issues of public relations issues namely 1) the administration of a special government agency affecting the work of public relations 2) Determining the person responsible for the public relations of Bangkok OTOP products that are inconsistent with the nature of the work 3) Adaptation of government agencies that are not keeping up with technology changes 4) Limited public relations budget. 5) Different entrepreneurs needs for distributing OTOP products in Bangkok. 6) Not dividing entrepreneurs by business size. 7) The ability to produce organic products that meet the needs of consumers appropriately 8) The image of OTOP products is not acceptable among Thai people 9) An application that is an intermediary in The market place has a high cost that operators have to pay for those applications. 10) In terms of organizing special events of OTOP Bangkok with a small number of OTOP entrepreneurs participating and some OTOP operators have to find channels for selfexhibiting in other provinces across the country where sales at trade shows have good sales. But have to pay in the shop or quite a lot of travel 11) Concerning the grouping of OTOP operators in Bangkok that is unclear and strong enough to perform the task As a result special events were not as successful as they should have been. 2.There are 9 strategies for public relations of OTOP products in Bangkok namely 1) strategies for fairing in special events of government agencies and private sectors 2) strategies for opening exhibition spaces for OTOP products in Bangkok 3) strategies for organizing OTOP products. Make public relations media in online and offline formats 4) Songwriting strategy for OTOP products in Bangkok 5) Online product distribution channel strategy 6) Telephone distribution channel strategy 7) Overseas distribution channel promotion strategy 8) Strategy Selection of Bangkok brands to enhance OTOP products in Bangkok 9) Strategies for storytelling in public relations
