Kansei engineering: product development methodology
Kansei engineering: product development methodology

Kansei engineering or effective engineering is an important product development methodology in which users’ or customers’ feelings and demands on the product are translated into important parameters for product design. On the other hand effective engineering is an application of users’ opinion mood and feelings in product design which seems to guarantee that the product will meet the demand of customers. This idea was first developed in early 1970s in Japan. Now it is widely used in both Asian countries such as Japan Korea Taiwan and European countries such as Sweden Spain and France. It is widely used in various fields like applied science and psychological science. This paper discusses the application of Kansei engineering in various daily-used products in both Japanese and Western lifestyles. The perspectives presented in this article are based on the authors’ engineering knowledge.

The purpose of this research is to study the effect of a safety system provided for external wall plastering activity on productivity by studying a construction of commercial buildings. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height along sides of the scaffold (4) installing safety nets around outside perimeters of the scaffolding (5) indicating working area (6) installing stairs (7) providing protection for people who works below (8) providing tools and equipments for transporting material which are safe and ready for using and (9) providing personal protective equipment for workers. Cost of the safety system is 79665 baht for a wall area of 1510 m2 or approximately 53 baht/m2. The prevention cost is quite high because it is an initial investment cost. However contractors could repeat theirs used on future projects. Productivity rates for prior and after the used of safety system are 1.16 and 1.13 m2/person/hr respectively. The productivity declines for approximately 3%. In addition our study found an impact of predecessor activity which is a brick laying activity. If brick walls are not well aligned and plumbed the working time for wall plastering could take longer for 8%. Meanwhile the wall plastering productivity could decrease for 11% and labor cost could increase for 12%.

Thai Local Herbs Snack Product (TLHSP) is very popular and has increase tendency the target group in worldwide such as children teenager and adult which live in metropolis. The aim was 1.) to study the formular and condition to produce TLHSP by extruder machine 2.) to study the type and quantity of Thai Local Herbs which was added 3.) to study the shelf-life and type of package to keep TLHSP. The study used CRD to design the method and has a stable variable is 1% CaCo3and varies 2 variables are the ratio between a speed of single screw at 3 levels such as 250 300 and 350 rpm and moisture content of raw material at 3 levels such as 15 17.5 and 20. And this research study about the level of grinded sugar (GS) at 3 levels such as 0 3 and 6 g. which at 3 g. the TLHSP had well scores of 7 to 8 (like moderately to like very much; used 9 Points Hedonic Scale method for the sensory test) the characteristic for color was 7.37+ 0.01 texture in crisp was 7.33+ 0.01 and overall acceptance was 7.70+ 0.01. Especially odor was 7.63+ 0.01 and taste was 7.38+ 0.03 there were significant differences (p<0.05) with 0 and 6% grinded sugar. TLHSP was well accepted by consumers with 88.00% (By the Central Location Test for questionnaire paper survey). Almost 70% were female 88% had 18-27 years-old 81% were student and 56% hadincome cash < 5001 baht/ months. This study used the extrusion technology to produceTLHSP which the fixed specification fallow as; a speed of single screw was 300 rpm Barrel temperature was 134-165 ˚C 380 Volt 85 amp a diameter in front of machine was 2 mm. a speed of blade 95 rpm and had 2 pieces.

The purposes of this research were to make artificial wild orchids from joint-vetch to imitate the natural one. Researchers studied joint-vetch dyeing Thai wild orchids forming from joint-vetch Thai wild orchids selecting by considering appropriate appearance shape and composition and five experts gave the opinions on the chosen researched orchids. The development of wild orchid product from joint-vetch was transferred to housewife’s group artificial flower entrepreneur and interested people in Phra Nakhon Si Ayutthaya province. The satisfaction of the research product was investigated from 60 target groups. The research’s results were: The appropriate types of Thai wild orchid were Ueang Matchaanu (Purple Bauhinia) Chang Iyares (Rhynchostylis retusa (L.) Blume) Ueang Sae Mon (Dendrobium bellatulum Rolfe) Ueang Sainamkrung (Dendrobium parishii) and Leuang Junthaboon (Dendrodium friedericksianum Rchb. f.). They were made into Thai wild orchid box Thai wild orchid bouquet Thai wild orchid garden in the glass and Thai wild orchid bouquet decoration. After the target groups attended the knowledge and technology transfer training course the investigation found was as follows: Most participants 73.33 % were female and 26.76 % were male. Most participants (33.33%) were in the 41-50 years age category and 26.66% were in the 21 – 30 years age group 21.66% were in the 31 – 40 years age group 10 % were more than 50 years old and 8.33% were younger than 20 years old. 33.33 % of the participants were famers 20% were freelance and merchants 16.66% were students and 13.33% were civil servant officers. The overall satisfaction of the participants after attending the training course was at the high level (4.73). Other aspects were found that the average mean (4.68) of the instructor was at the highest level. The average mean (4.74) of the facility was at the highest level. The average mean (4.71) of the product was at the highest level. The average mean (4.35) of the understanding was at the high level. The average mean (4.73) of the knowledge application was at the highest level.
