Research paper : Products and evaluation device of cosmetics for UV protection (Y. Takao et al.)−150−Synthesiology - English edition Vol.3 No.2 (2010) transparency and texture-feel of the cosmetic powder by developing a new compositing technology for the UV-blocking nanoparticles and cosmetic ceramics. However, the text states the achievement of all three issues including UV-blocking, transparency, and texture. Since UV blocking is a default for cosmetics, I think there are two issues, the achievement of transparency and texture. What is your reason for setting UV blocking as a distinctive issue?Answer (Yasumasa Takao)As you indicated, it is not necessary to list UV blocking because it will be consequently obtained by using the nanoparticles. Since currently there is no technology to arrange the nanoparticles appropriately on the surface of the particle, the nanoparticles must be restrained excessively to achieve both transparency and texture, and as a result, UV blocking function may be lost.3 Issues of technological elementsComment (Toshimi Shimizu)In the first draft, you write that the issues of technological element are “UV blocking”, “transparency”, and “texture-feel”. These terminologies are perceptive and non-technological expressions. From the perspective of basic physical properties, I recommend they be, for example, reworded as “high UV blocking property”, “high transmissivity of visible light”, and “high lubriciousness”.Answer (Yasumasa Takao)As you indicated, I made revisions to use the appropriate terms that express the physical properties.4 Relationship between lubriciousness evaluation device and technological issuesQuestion (Toshimi Shimizu)I understand that you first developed the evaluation device for lubriciousness to qualitatively assess the texture-feel. However, you did not describe how you overcame the technological issues by setting what kind of manufacturing condition as technological issues to obtain good texture-feel, or in another word, high lubriciousness, for the UV nanoparticle-ceramics composite material. Does it mean you solved this technological problem simply by trial-and-error? I cannot quite follow the logic of how the good texture-feel was achieved by developing the evaluation device.Answer (Yasumasa Takao)One of the reasons for good texture-feel is the effect achieved by controlling the segregation of nanoparticles between the sericite and arranging them only on the material particle surface, and as a result, minimizing the use of sericite and nanoparticles. This point was added to the text.5 Three types of synthesis method in SynthesiologyQuestion (Kazuo Igarashi)In the first draft, you cite the three types of synthesis method described in Synthesiology, 1(2), 139-143 (2008) (SynthesiologyEnglish edition 1(2), 131-137 (2008)). When you are comparing them to the case reported in this paper, what exactly are you comparing? Also, you mention the integration type technological and social solutions, but what does this mean?Answer (Yasumasa Takao)As the methodology for solving the social elements, Synthesiology proposes three types of methods: (1) aufheben type, where two contradicting proposals are temporarily “sublated” to create a new concept, (2) breakthrough type, which is the unique growth model of the core technology, and (3) strategic selection type, which is the investigation of hypothesis through a logical scenario. This research can be considered a case where the (1) aufheben type idea is applied to the social elements in the sense that the short-term organizational interests are temporarily sublated or suspended.6 Social solutionQuestion (Kazuo Igarashi)Please describe what you mean when you say that the social solution will increase the product competitiveness by a combination of regional brand and original manufacturing method.Answer (Yasumasa Takao)The researches of synthesis (material) and evaluation (device) were not set in the preliminary scenario, to enable flexible use of the usable core technology. As a result, the composite particle from the synthesis research guaranteed the wide applicability of the evaluation device, and therefore, the device research contributed in achieving the higher function of the powder material. In another word, the researches for synthesis and evaluation contributed to the mutual solution of the technological elements and to the increased competitiveness of the social elements.7 Feeding route selection by antsComment (Kazuo Igarashi)In the first draft, you mention the “feeding route selection by ants” as a comparison to the natural phenomenon, and describe the similarity of the logical structure to that. However, the general reader does not know about the logical structure of the feeding route selection by ants. Moreover, I cannot see the relationship between the scenario of this paper and the advantage of enhancing the method by promoting the discovery of a new route.Answer (Yasumasa Takao)The important viewpoint of this paper is “the optimization of the individual may not necessarily be the optimization of the whole”, and I added the description to clarify this point in the revised text.
