The detailed scenario is described in chapter 2, and the synthesis methodology is discussed in chapter 3.For the “social elements” including the specific idea suggestions for materials and manufacture methods, as well as the adjustments of differences in organizational interests, we propose the regional cooperation in the style of the Agency of Industrial Science and Technology[1][2], or trial-and-error based on experience (Fig. 1(b)).The powder material for cosmetics and the evaluation device were commercialized[14]-[21], through the application of core technology for the ceramic powder unit operation[1], the establishment of evaluation technology by AIST grant venture[2], and the long-term cooperation where short-term organizational interests are temporarily suspended[8]-[13] (chapter 4). We shall investigate the process of solving the social elements as an R&D methodology by referencing the recent comparative researches[3]-[8] or the analogies to the natural phenomena[22]-[29] (chapter 5).2 Scenario for solution2.1 Scenario for solving the technological elementsTo achieve (1) UV protection, (2) transparency, and (3) good texture in cosmetics, it is mandatory to establish a manufacturing method where the three technological elements (1) high UV blocking, (2) high visible light 1 Background of research: Issues and problems of the “UV-protective cosmetics”The objective of this paper is to present a case study for an R&D methodology that combines a strategic scenario and the empirical trial-and-error, taking the ceramic powder technology as an example (Fig. 1).For today’s cosmetics, the technological element that is most desired is to block off the harmful ultraviolet (UV) rays, in addition to transparency and good texture. As shown in Fig. 2(a), when nanoparticles, which consist of particles of several 10 nm size for light scattering effect and titania with band gap effect for blocking the UV-B, are added to the cosmetic ceramic particles for UV protection, uneven nanoparticle aggregations occur among the ceramic particles. The nanoparticles must be added excessively to achieve the desired UV protection, and the resultant aggregate particles shield the visible light and therefore decrease transparency, and produce high friction or decrease smoothness of the texture. Yet, the UV protection effect will be insufficient when the amount of nanoparticles is decreased to prevent the decline in transparency and texture, and we are faced with a dilemma[1][2].Therefore, in this study, we propose the composite particle[1] and the least-square (LS) approximation model[2] as the AIST-style strategic approach[3]-[7] to solve the “technological elements” of UV protection, transparency, and texture. The AIST-style strategic approach is the development and - AIST commercialization based on regional collaboration that combines the current strategic logic, and an intermediary’s experience and trial-and-error approach -Yasumasa Takao*1 and Mutsuo Sando21.

Recently, cosmetics need to solve 3 problems simultaneously: 1) UV-protective effect, 2) transparence, and 3) smooth-textured touch. However, the best recipe and usable evaluation methods are not established. This research is the result of a strategic regional cooperation of the AIST grant venture and the technical guidance that did not set a prior scenario with immediate effect of the national research institute. A new manufacturing and evaluation method has been commercialized in the forms of a highly original cosmetics and a new evaluation device. An example of the methodology is shown concerning social elements (regional cooperation), particularly. The example is illustrated by comparing 2 elements. The first is the R&D methodology that the Synthesiology journal advocates (the Aufheben type, breakthrough type and strategic selection type). The second is the humanities way of thinking by analogy with natural phenomena such as the evolutionary theory.Products and evaluation device of cosmetics for UV protectionKeywords : Ceramic composite particles, UV-protective cosmetic, shearing evaluation of powder-bed, apparatus engineering, Agency of Industrial Science and Technology, AIST grant venture[Translation from Synthesiology, Vol.3, No.2, p.127-136 (2010)]
