This study aims to survey the demand of the sub district administrative staffs in Phitsanulok province for self-development about administrative knowledge. The result showed that the essential knowledge for administration in the sub district administration organization requested via staffs was divided into 7 aspects. Knowledge development in financial accounting and taxation computer management profession education public health and environment was in the high level requirement whereas they have a medium level need for marketing knowledge improvement. Computer and the Internet were the highest requests. The follow was the knowledge about waste management. The effective and proper methods for knowledge development should be two day workshop in weekday (Monday to Friday) and the most available time was daytime (08:00–16:00). The speakers should be the government or public organization rather than private sector. The most proper total budgets (including food drink and documents) for workshop ranged from 500–1000 baht.

The natural rubber with silica masterbatch was produced and used as based material in rubber compound modified from standard tread formulation given in ASTM E 1136. The reduction of mixing energy and rubber vulcanizate properties were investigated. Results indicate that in comparison with STR 5L compound the rubber with silica masterbatch i.e. fresh latex (FNRmSi) low viscosity natural rubber used 1.0 phr of hydrogen peroxide (LNR1mSi) and low viscosity natural rubber used 0.34 phr of hydrogen peroxide and 2.7 phr of potassium persulphate mixture (LNR2mSi) provides maximum mixing energy saving of 30.48% 33.37% and 37.20% respectively. The scorch time and cure time rise with increasing filler loading. The mechanical properties of LNR1mSi and LNR2mSi are similar to those STR5L compound whereas FNRmSi vulcanizate shows superior mechanical properties such as 300% modulus tear resistance abrasion resistance elongation at break and tensile strength. The homogenous distribution and interfacial interaction of silica filler and natural rubber matrix were enhanced by the self-assembled silica masterbatch as shown by the fracture surfaces morphology of the vulcanizate using a Scanning Electron Microscope (SEM). The silica masterbatch form has reduced the mixing power consumption and enhanced the mechanical properties.

The objective of this research was to study the effects of the processing method on colorant powder from Carissa carandas L. mixed with maltodextrin 3 levels (10 13 and 16 %). The physical properties and consumer acceptance on cotton ball cakes added colorant powder from Carissa carandas L. mixed with all maltodextrin were added at 15% on flour weight. Results from physical properties of cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 10 % was found that the lowest lightness. But also the cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 16 % was exhibited the highest redness and yellowness (p< 0.05) and water activity range from 0.92 to 0.93 (p> 0.05). However the cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 13 % was showed that the highest hardness and chewiness (p< 0.05). Furthermore the colorant powder from Carissa carandas L. mixed with maltodextrin at 10 % was found the lowest adhesiveness (p< 0.05). In addition sensorial evaluation was accepted overall liking score in range 7.63-7.80 (like moderately to like very much. The produce colorant powder from Carissa carandas L. was added maltodextrin from 10 to 16 % (w/w) on (p>0.05).

The purpose of this research is to study Quality of work life affecting Organizational Commitment of private companies’ employees in Lopburi Province. Sample size in this research is 400 samples. Questionnaire is a tool for data collection. Statistics for data analysis are percentage mean standard deviation t-test one-way analysis of variance and multiple regressions analysis. Research results are as follows: Organizational commitment in the dimension of Strong belief in and acceptance of the organization’s goals has the relationship with Development of Human Capacities and Social Relevance. Organizational commitment in the dimension of Willingness to exert considerable effort on behalf of the organization has the relationship with Adequate and Fair Compensation Development of Human Capacities and Work Life Balance. Organizational commitment in the dimension of Strong desire to maintain membership in the organization has the relationship with Adequate and Fair Compensation Growth and Security and Social integration.

The Applicability of the Royal Sufficiency Economy Principles to Community Enterprises Management in Surin. The objective was the possibility of applying the Royal Sufficiency Economy Principles. And compare investigate the possibility of applying the Royal Sufficiency Economy Principles. The sample is 316 firm from Community Enterprises in Surin is 1440 firm. The research found that Most of business was industry enterprise. Has capital an average of ฿146606 from private and relatives. The size of the enterprise community (NAV) of less than one million employs up to 10 people with qualifications below bachelor degree have annual sales of less than 2 million settlement enterprise in their local distributor. And supply of raw materials and equipment used in the production of their own local. The possibility of the application the Royal Sufficiency Economy Principles there is at a high level. And Compared to the possibility of applying found that communities that are difference characteristic there is a possibility of the application no difference on the 0.05 significance level.
