The purposes of this research were to explore 1) the characteristics of successful entrepreneur: case study of Pailin Couture and 2) the factors affecting of self- employed of students who study major in fashion clothing and textiles design faculty of home economics technology at RMUTP. Using mixed method research and divide the data into 2 parts: 1) collected data from the entrepreneur as a key informant by using structure interviews and analyze data by content analysis and 2) collected data from students whose are selected using purposive sampling technique using questionnaire and data was analyzed using frequency percentage mean and standard deviation. The finding was concluded as follows: Characteristics of successful entrepreneur consist of: 1) inspiration from clearly know themselves and led to career 2) have experience or preparation about finding a place to study work-in-study finding a team coaching and channel expansion 3) working approached were to maintain harmony conflict reduction and do not use the mood to work 4) problem solving solution was to find the cause of the problem and consciousness in solving problems 5) core concept in occupational was takes a shorter time to learn but take it to career quickly and have creative development 6) category of products or services was variety of clothing styles 7) recruitment must choose who had the knowledge and ability in work and 8) recommendations for the couture entrepreneur should have knowledge and skills such as product planning team building marketing plan and target group of business. The factors affecting of self-employed of students found that: expectations of parents after graduation was self-employed. Individual factors toward to self-employed were love to work independent interesting in self-employment and love to learn more. Job factors toward to highly self-employed were individual challenge extremely in use ability and interpersonal relation.

The effects of load frequency control (LFC) of interconnected distribution power system in tie-line substation area load –frequency stability and the frequency respond at distribution generator (DG) are very important for interconnected control power system of tie-line area. The generating power system of solar farm and wind turbine which have interconnected distribution power system in tie-line substation area were tested using 3 simulation parameters: non-controller Automatic Voltage Regulator (AVR) and with Pl Controller. The results showed that there were 3 types of load and frequency changing in the interconnected area: load changed 0.02 p.u. had frequency of load changed 0.025 Hz and large disturbance. Comparisons of load-frequency to respond for steady state the time respond was 7.9 seconds for non-controller 5.4 seconds for AVR and 1.7 seconds for under controlled system at 0.1 p.u using Pl controller. Therefore the Pl controller has better efficiency than non-controller about 31 % and AVR about 16%. It can be concluded that the interconnected distribution power system in tie-line substation area controlling for storage for connected grid had better efficiency and optimization of generating power from renewable solar farm and wind turbine which have interconnected distribution power system in the nearby are balance of controlling of the original system.

This paper presents the investigation of pozzolanic reaction of rice husk ash blended with fly ash by accelerated curing. The compressive strength of cement paste containing rice husk ash blended with fly ash at 30% by weight of cementitious material (PBA-30) was studied. The temperature curing at 60 70 and 80oC were parameter of test in order to determine the suitable temperature and curing period on strength development of cement paste. The ratio of rice husk ash to fly ash was 1:1 by weight and the ratio of water-to-binder (w/b) was 0.38. The test results found that the accelerated curing of PBA-30 at temperature of 60oC for 5 10 and 45 hours had comparable compressive strength to PBA-30 with normal curing at the age of 37 and 28 days respectively. As a result of accelerated curing the calcium silicate (CS) which effect on strength development of cement paste was increased. According to the X-ray diffraction analysis the calcium silicate content in cement paste was comparable. Therefore it can be use accelerated curing to investigate the poozolanic reaction of rice husk ash blended with fly ash within 48 hours.

This research aimed to study powe generation from heat loss strove by thermoelectric generator unit. As cooking with a gas stove can cause heat loss between the stove and the cookware this heat loss from gas stove can be converted into the electricity. For the experiment the researcher used a gas stove model KB5 installed with thermoelectric plate model TEG1-241-1.4-1.2 connected in a series to the power of 4 modules. Then experimental conditions of the gas pressure in the gas strove were set at 0.1 0.2 0.3 0.4 0.5 and 0.6 kg/cm2 respectively while the amount of mixed air was constant during the experiment. The results showed that when the gas pressure was at 0.6 kg2 the temperatures of the hot side and cold side of the thermoelectric generator was equal 250.5oC and 65.5oC respectively. Lt also generated the highest electric power of 53.3 watts. The power conversion efficiency was 5.3% at 38.1 Volts with 1.4 Amperes. In addition when electric was connected to a thermoelectric generator unit with 12 VDC 7-watt LED bulb the gas pressure in the gas stove were set at 0.3 0.4 0.5 and 0.6 kg/cm2 respectively was affected by the difference between the heating temperature and the cold temperature in the range of 185o C that could lighten up LED bulb.
