Thailand is one of the few countries in the world that provides the whole value chain of the textile industry with over 4700 local textile producers and 800000 to one million workers making this industry the second-most important employment sector. In 2016 the industry’s export revenue was valued at almost USD 7 billion contributing to over 3% of total exports. The Association of Southeast Asian Nations (ASEAN) is the biggest international market for Thailand clothing export (23%) and expected to become the worlds fourth largest market by 2030. However Thai cloth entrepreneurs are facing major problems that demand attention including labour costs new design and product development and in particular online marketing. The Thai fashion and textile industries should define a clear strategic move through integrating textile with fashion with a view “toward sustainable creative industries with strong soft power”. The purpose of this study is to analyse competitiveness of Thai cloth entrepreneurs in relation to online management and integrated marketing communications (IMC) in the ASEAN market. The research instrument involves a descriptive cross-sectional mixed-method study in Thailand. For quantitative data 60 cloth entrepreneurs are invited to complete a questionnaire before and after our “online management and IMC” training programme and a qualitative in-depth interview study is conducted with 10 cloth entrepreneurs. The 2017 survey returned 100% participation with general agreement that a website and Facebook are the most important IMC tools for online marketing in the ASEAN market. Before training the participants had knowledge and skills regarding the ASEAN Free Trade Area (AFTA) online communication and social media tools in intermediate level while they had less knowledge and skills concerning social media web design and online gallery. After training the statistics show an increase in entrepreneurs’ level for all knowledge and skills. Furthermore the findings from in-depth interviews show that with regard to entrepreneurial competitiveness in relation to the ability of online management and IMC there is a requirement for further training and government support. In addition the 10 cloth entrepreneurs agree that time management and quality of product and service control are very important for online business.

Music Piracy Is A Ever-Changing Challenge – Thailand’s Music Market Continues To Be Distorted By Unfair Competition FromUnlicensed Services Which Affects Income Of Rights Owners. In Order To Find The Solution For Music Industry The Purpose Of This Research Is To Determine Integrated Marketing Communication In Campaign Affecting To Deter Unauthorized Buying Or Downloading Of Copyrighted Music. The Research Tool Employed In This Study Is A Questionnaire To Enable Statistical Analysis From The Desired Sample Of 410 Subjects Around Thailand And 60 Subjects Who Were Trained In This Programme Regarding Copy Right Music. The Results Show That Integrated Marketing Communication For Communications In Campaign To Deter Unauthorized Buying And Downloading Of Copyrighted Music Which Includes; Advertising Sale Promotion Public Relations And Direct Marketing Cannot Change Consumers’ Behaviour To Stop Music Piracy. However The Chi-Square Test Results Show That Consumers’ Decision With Regard To Deter Unauthorized Buying And Downloading Of Copyrighted Music Depends On Price Law Social Acceptance And Religion Belief With A Level Of Significance At 0.01. Hence We Can See That Thailand’s Music Industry Is A Business Whose Success Depends On These Factors. It Recommend That Government Policy Makers And Entrepreneurs Should Target Direct Strategies With A Greater Focus On The Role Of Them.

The objectives of this research are to study the rate of deterioration of tyre friction coefficient and investigate the quality of new and old tyres that are currently in use. A set of the rolling resistance testing was designed and set up to work with the single dynamometer according to speed 80 km/h tire load 4660 N and inflation pressure 30 psi. There were three tire samples new tire one year used tire and two year used tire to find the rolling resistance coefficients. The finding shows that the rolling resistance was inverse variation with tire aging. For instance the new tire (1st sample) had the highest rolling resistance on the other hand the two year used tire (3th sample) had the lowest rolling resistance. Moreover the rolling resistance coefficients were inverses variation with tire aging. Besides the one year used tire had the average of the decreasing rate of the rolling resistance coefficient at 0.03689 N/kN per a week while the two year had the average of the decreasing rate of the rolling resistance coefficient at 0.03671 N/kN per a week. Furthermore the result also revealed that the rolling resistance coefficients nonlinearly decreased comparing to the tire aging.
