Dust is a major problem to effect of health especially in formal sector that is not covered by health benefits. This study was proposed at investigating the total dust and particulate matter (PM10) of workers in Thumley Teptaro Wood Handicraft industry Trang Province. Survey and sampling of dust from all operators were collected three replications using a tracking ID on working period. The results showed that were two groups of Thumley Teptaro Wood Handicraft industry that total dust were 7.7540+1.3110 and 14.4162+0.9265 mg/m3 and PM10 were 8.6134+1.4806 and 4.5279+0.8743 mg/m3 respectively. Total dust and PM10 were significant difference (P<0.05). PM10 in the wood product process of Thumley Teptaro Wood Handicraft industry were 3.3422+0.6685 2.9630+0.3050 and 4.5279+0.8743 mg/m3 in sawing frog style and polishing respectively. This result indicated that total dust and PM10 in all production process of Thumley Teptaro Wood Handicraft were not exceed the standard of Occupational Safety and Heath Administrstion and the notification of Interior Ministry about safety environment in workplace. Working behavior was found that workers were affected by total dust and PM10 in wood production process. All workers used dust protector during operators work.

An experimental design was a completely randomized design (CRD). Fifteen Thai native cattle were randomly allocated into 5 treatment groups with 3 animals in one group and one cattle was one replication assigning to be fed with various roughages: (1) fresh Napier grass (NP) (2) fresh oil palm fronds (OPF) (3) oil palm fronds silage (4) OPF silage with 2% of molasses and (5) NaOH treated OPF (1.5% by weight OPF). All treatments were supplemented with concentrate feed consisting of 14% of crude protein at the rate of 1% of live weight (BW). The experimental period was 120 days. The data were analyzed with analysis of variance and mean comparisons among treatments were Duncan’s multiple range test (DMRT). The results showed that no significant differences (p>0.05) were observed among 5 treatments in feed intake of dry matter digestibility of crude protein digestibility of neutral detergent fiber feed conversion ratio and growth rates. However the lowest production cost for 1 kg gain was obtained from the cattle fed with NaOH treated OPF.

This research was to study the feasibility of CIGS for condominiums in Thailand by studying the energy consumption of building which divide by behavior of users which interested in day time users and night time users. Then study approach and feasibility to apply CIGS for condominiums by consider energy consumption and economic efficiency of installation CIGS for energy conservation. The result showed that when installed 110 watts/m2 of CIGSs on windows in a room type can be provide electricity 2.51 kWh per day 2.81 kWh per day and 3.75 kWh per day which can be represented 40 percent of the total energy consumption. In other word can be reduce energy supply from grid per month 75.30 kWh 84.3 kWh and 112.50 kWh. While investment cost per square meter of CIGS is about 23000 - 35000 baht which equivalent to 3 percent of total condominium price that mean payback period is about 8 years. Although CIGS is not able to provide all of electric consumption in building but from the assessment of economics found that there is a very interesting to investment it should be interested policy for the government to enforce condominium to install CIGS for sustainable development.

This study aims to study the process of producing brown rice by housewives group who produced brown rice as otop product from Narathiwat Province. They designed and developed brown rice machine of PNU III. The machine were formed from a peeling machine fan for husk peeling sorted out rice and paddy machine paddy vascular system and wipe machine. They were formed as brown rice machine and given to housewives for producing brown rice as local product called otop in Narathiwat province. They brought Kradangga seed rice that exist in Narathiwat and exposed them to the sun up to 13-15 percent high then they were milled. From the experiment the study found that the distinction of rubber speed has caused the machine producing the brown rice with 93 kilograms per hour by using 3 HP motor energy. From the experiment it can be concluded that brown rice machine of PNU III has the quality and it is appropriate and good for increasing the product quantity to the housewives group

This paper presents a quadrature sinusoidal oscillator providing sinusoidal signal which differs in phase. The features of the proposed circuit can be electronically controlled. The proposed circuit consists of 4 operational transconductance amplifiers(OTAs) and 2 grounded capacitors which is able to control the oscillation frequency(OF) and condition of oscillation(CO). To confirm the performance and theory of proposed circuit is verified by PSPICE simulations and the experimental results can be achieved by using the commercial parts(LM13700s). The power consumption is about 33.3mW at supply voltages
