การพัฒนานวัตกรรมผลิตภัณฑ์ทำความสะอาดและฆ่าเชื้อโรคในสถานการณ์ COVID-19

The purpose of this research was to develop innovative cleaning and disinfection products in the situation of COVID-19 and to transfer the production technology of innovative cleaning and disinfection products. The innovative product developed is a semi-liquid alcohol gel. The sample group used in this study was volunteered consisting of 10 people. The research tool was the satisfaction assessment form technology transfer and the development of innovative cleaning and disinfection products in the situation of COVID-19. Data were analyzed using statistical software packages. The statistics used were mean and standard deviation. The results showed that. 1. Innovative cleaning and disinfection products in the situation of COVID-19 developed as an innovation of semi-liquid alcohol gel products. Which has a concentration of 73.0 % v/v 2. Most of the trainees were satisfied with the overall technology transfer. Both speakers places periods facilities knowledge and benefits from receiving services are high. 3. Most of the trainees were satisfied with the technology transfer pattern as well as the duration of the training. Product innovation process Product innovation can be put into practice and product innovation is a guide to careers at a high level.

This research presents the development of ultrasonic scaler for mobile dental unit. The operation of the scaler uses a phase-locked loop circuit to generate high frequency electrical signal. Then the signal is amplified with a Darlington amplifier circuit to feed to the coil in the Hand Piece resulting in Magnetostriction. This phenomenon causes the stretching and shrinking of the magneto-strictive stack with high frequency which causes the tip of the scaling head to vibrate more than 20000 times/second. Traditional ultrasonic scaler for mobile dental unit has thermal problem of the amplifier circuit due to use of the transistors as the switching devices. When used for a period of time the scaler is necessary to stop working resulting in not much scaling per day. This research solved the problem by using MOSFETs as switching devices and adding cooling system to the amplifier circuit. The experiment was carried out using actual conditions. The experimental results show that the developed scaler has increased the number of scaling per day. In addition it will still remove plaque and dirt in the gumline around the base of the teeth similar to the scaler used by general dentists.

การพัฒนานวัตกรรมทางการบัญชีของธุรกิจขนาดกลางและขนาดย่อม (SMEs)
การพัฒนานวัตกรรมทางการบัญชีของธุรกิจขนาดกลางและขนาดย่อม (SMEs)

This research aimed to study organizational characteristics and organizational supporters that affect the innovative development of small and medium enterprises (SMEs). The independent variables were organizational characteristics based on McKinsey’s 7S framework (strategy structure systems style staff skills and shared values) and organizational supporters (technology and government support). The dependent variables were guidelines for accounting innovation development. Sizes of the organization were control variables. The sample group in the study consisted of 309 small and medium enterprise entrepreneurs. Data were analyzed using descriptive statistics and inferential statistics (multiple linear regression). The results showed that strategy systems staff technology and governmental support affect the innovative development of small and medium enterprises (SMEs) at the .05 level of significance. According to small and medium enterprise entrepreneurs management accounting innovation and financial innovation were very important to SMEs (X ±S.D. equal 3 . 6 1 ± 0 . 8 2 ) . To develop SMEs’ accounting innovation entrepreneurs need to determine clear strategies policies and goals for innovation manage data systems to be exchanged in organizations and set a motivation system for innovation development. Staff development plans should be created for knowing and understanding innovation. Apart from organization management SMEs need to get government support and adapt technologies to accounting to increase the efficiency of accounting information.
