Forum: Letters from Readers(Aug. - Sept., 2016)

Naohiko Takayama, Masaaki Shibuya, Takeo Yamamoto, Yorikazu Suwa, and Toru NakagawaTakayama, in response to 'Do We Have Any Methodology of Creative Research in Academia ?', has made mind maps of James Young's book and of Darrell Mann's book and suggests some parallelism between them. Shibuya has pointed out the recent remarkable advance of statistical science using computers and evaluated that such statistical methods are successful in analyzing real data starting with simple models and obtaining fairly complex results, corresponding to the abstraction and concretization processes in the CrePS methodology. Genom analysis, financial engineering, brain science, speech recognition, etc. are such application areas of success, he says. I have been thinking the data analysis with computers in a somewhat separate framework from the problem solving by humans. But I feel we need to consider the data analysis methods with more weights in our CrePS methodology. Yamamoto sent me a comment in late June that we should consider the high risk of Japanese financial catastrophe more seriously in parallel to the poverty problem. He communicated to me again in response to my visual diagram of Professor Hiroshi Yoshikawa's lecture on 'Financial reconstruction and Japanese economy'. Suwa contributed his thoughts on the Low-living Elderly problem, based on his experiences of meeting a number of LLE people in his job as a judicial scrivener. His communication is posted in a separate page [2].

[2] Social Problem:

On the Low-living Elderly Problem: Employee's pension insurance should be applied more widely Yorikazu Suwa (Judicial Scrivener)   The contributor, Mr. Suwa, worked in sales divisions in a big company and after retirement he became a judicial scrivener. Servicing for lawsuits at Summary Court, he met a number of low-living elderly people who are suffering from debt in consumer finance. From such a background, he writes his thoughts in an sample case: A woman who worked for 30 years as a secretary in a foundation is now old in age with no family/relatives and in a hospital. So the foundation is asking its members for raising money for her medical care. She does not have employee's pension, as a matter of fact. In 1975 when she started working at the foundation, Employee's Pension Insurance (which is to be paid half and half by the employee and the employer) in Japan may not be applied to corporations with less-than 5 employees. In 1981 the Employee's Pension Act was changed so that any corporation has to apply the employee's pension to all its employees. But the Act was not enforced strictly and many corporation, including her foundation, did not join the insurance. Missing the chances of joining the insurance, or intent violation by corporation employers, is one of the most significant factors for many elderly people to fall down into low-living situations.

In 1981, a notice was issued by the director of Health Insurance Department of Ministry of Health and Welfare, saying "The part-time employees working for the time length less-than 3/4 of the regular employees are not applicable for the Employee's Pension Insurance". This notice is a big problem because it excluded a huge number of non-regular employees out of the benefits of Employee's Pension.

-- Since I have few chances of facing real situations of poverty in the society, I am not good at thinking and talking on real sample cases. Suwa contributed to explain focal points of real problems on the basis of his experiences. He is another old friend of mine at the YMCA dormitory of the University of Tokyo. I deeply thank him for his valuable contribution.


[3] CrePS Introductory:

Fuda-Yose Tool and Visual Thinking: Part 3: Practices of Using the Fuda-Yose Tool:         Practices by Nakagawa for Visualization Toru Nakagawa

This is the Part 3 of the series of papers jointly written by Akihiro Katahira and Toru Nakagawa.

In this Part 3, Nakagawa describes his practices of using Fuda-Yose method at the phases when the problem has become clearer and some notes/documents are written either by him/herself or by other person(s). The purposes of using the Fuda-Yose tool is to clarify the logics in the documents by making visualized diagrams and to share the understanding with many other people. I explain the basic thoughts of my practices, first, and then describe the concrete process of making visualizing diagrams for the documents typically of the length from half a page (e.g., abstract of a paper) to about 20 pages (e.g., an article/paper, or a chapter of a book). Cases of visualizing practices are chosen from my reports already posted in this "TRIZ Home Page in Japan":

they are

(1) Abstract of Ed Sickafus' paper, and five chapters of Takanori Fujita's "The Low-Living Elderly" book (including;

(2) Introduction,

(3) Cases of falling into the LLE situations,

(4) Higher risks of LLE in near future,

(5) Feelings and thoughts by ordinary people on LLE, and

(6) Author's proposals of LLE policies), and

(7) Lecture note by Prof. Hiroshi Yoshikawa on 'Financial reconstruction and Japanese Economy'. For each example, I explain the process of making the visualizing diagrams, ideas for improving the diagram representation, the finished (rather detailed) diagrams and their simplified versions made on readers' requests, etc.

These examples demonstrate that the visualization with Fuda-Yose Tool is useful for clarifying the logics in documents on complex themes like these social problems. It is required to visualize the logics in much larger documents with different arguments (because all significant social problems and political issues are such cases). Our strategy should be 'Segmentation and Hierarchical structuring'; we need to demonstrate it from now on.

Best wishes,

Toru Nakagawa

[1] Business TRIZ Introductory:

   Breakthrough Thinking with TRIZ for Business and Management: An Overview

     (Valeri Souchkov (The Netherlands);

     Japanese translation: Toru Nakagawa) (Nov. 23, 2016)

   An excellent introductory article by Valeri Souchkov posted

   in his Web site is translated into Japanese and is posted

   in the Japanese page of this site.

   In the English page, table of contents of his 20 page

   article is shown for your reference, together with the

   links to his earlier introductory articles appeared in

   the present site.

   The present article introduces TRIZ and its use for

   business and management to the ordinary business people

   in plain words without any prerequisite.  

   He puts stress on the way of thinking rather than tools.

   His way of using TRIZ for business and management has been

   proven to be easy to learn and effective to apply.  


[2] Conducting a Training Seminar on 'How to Prepare and Write Reports',

     (Toru Nakagawa)                         (Nov. 28, 2016)

   Every year since July 2010, I have conducted a training

   seminar on 'How to prepare and write reports' for 2 days

   (12 hours) to 50 nurses at Wakayama Prefectural Nursing


   The seminar is a part of the First Level (for 150 hours) of

   the Course for Certified Nurse Administrators, organized

   by Japan Nursing Association.

   For the training text I use my article 'How to Prepare

   and Write Reports: Preparation of the Contents, Building

   the Structure, and then Writing Sentences', published in

   Communications of OGU and posted here on Oct. 10, 2010.

   I also give a presentation on 'How to Think for Creative

   Problem Solving', with 3 case studies,so as to demonstrate

   the Six-Box Scheme paradigm.

   Group exercises are also carried out.

   I use excerpts from OGU students' reports and ask the nurse

   trainees to brush them up.

   Then we go ahead to review and improve the nurses' own

   reports which were submitted beforehand for the course on

   the theme of 'Situations and tasks at my own work place'.

   See some more introduction in the English page.

   This training program has received much appreciation,

   to my pleasure.


[3] CrePS Research Note:   both in English and in Japanese Six-Box Scheme Representation of Published Papers

   (1) 18 Papers by Toru Nakagawa (2000 - 2016)

     (Toru Nakagawa)              (Dec. 27, 2016)

   18 papers which I published at international/domestic

   conferences every year since 2000 are represented in the

   overview format of the Six-Box Scheme,

   and are shown here together with their Abstracts,

   both in HTML (images) and in PDF .

   You may understand, I hope, the concept of the Six-Box

   Scheme, ways of representing works in the Six-Box Scheme overview, and also a history of my work for developing them.

   The Six-Box Scheme is a new paradigm of creative problem

   solving, which I found in 2004 in my study of TRIZ and USIT

   and I have been promoting activiely in a much more general

   context since 2012.  

   For the purpose of demonstrating the Six-Box Scheme, I have

   been trying till recently to make new case studies where

   various types of problems are solved along the Six-Box

   Scheme with some methods like USIT.  

   The demonstration has been proceeding only slowly with a

   limited number of case studies.

   I now realize, however, that almost all serious intellectual

   activities and their results can be described properly in

   the Six-Box Scheme.  

   Thus I made trials to describe a selection of my papers

   which I published in 2002, 2004-2005, 2012, and 2014,

   in the Six-Box Scheme.  

   Since the repesentations were found meaningful, I have

   described my 18 papers published every year from 2000 to

   2016 in the Six-Box Scheme, as you see here.

   Every published paper can be represented properly in the

   Six-Box Scheme, and should be worthy of doing so.  

   The Six-Box Scheme has such generality as a basic paradigm

   of creative problem solving.  

   Some of the papers, of course, emphasize some parts of the

   Six-Box Scheme and skipps some other parts.

   That is all right.

   The Six-Box Scheme representation plays the role of a

   template for describing intellectual activities/works,

   just like the standard format for filing patents.

   Michael Orloff (Germany), Syed Kamarulzaman Syed Kabeer

   (Malaysia), Sergey Sobolev (Russia),

   Valeri Souchkov (The Netherlands), Czes?aw CEMPELPoland);

   Toru Nakagawa

   M. Orloff writes the needs of modernizing and structuring

   TRIZ, and introduces his activities of educational and

   executive applications of his Modern TRIZ (MTRIZ).

   I made communications to V. Souchkov for preparing the

   Japanese translation of his article on 'TRIZ for Business

   and Management', and learned about a free software tool

   'yEd' for drawing diagrams.

   He mentions that he delivered a keynote lecture at a

   Russian domestic TRIZ conference to 350 participants and

   that in various countries in the world TRIZ proliferation

   activities are in good progress.

   C. Cempel is interested in the contradictions between

   Liberty and Love and further with Equality.


[4b] Japanese page:

   Akihiko Ikeda; Akio Harada; Tsunehisa Maekawa; Tatsuo Torii;

   Kozo Kuchitsu; Takehiko Itoh; Toru Nakagawa

   A. Harada mentions that the slogan of 'Liberty, Equality,

   and Love' of the modern world since the French Revolution

   may need to be reconsidered.

   Nakagawa responded: "Equality is a principle at the base of

   Fundamental Human Rights and hence at the core of Ethics.

   Since both Liberty (The 1st Principle) and Love (The 2nd

   Principle) are motivated and developed by Ethics, we may

   regard Ethics as The 0th Principle of Human Culture."

   T. Maekawa communicated about National Contest of

   Statistical Graphs for Elementary and Junior High School

   Pupils; 2 pages of his communication are posted in small


   The entrance page "Let's enjoy 'Think & Try' !" of the

   present home page has not been updated for over a year.

   I wish to have some voluntary co-Editor for this part.

   T. Torii writes "Toshio Takahara's theory is great for

   understanding contradictions systematically.

   I wish you dig much further concerning to the Principal

   Contradiction 'Liberty vs. Lave'."

   Professor K. Kuchitsu (who guided me as Associate Professor

   and Professor during my years of undergraduate, graduate,

   and Assistant) evaluated my recent article on 'How to

   prepare and write reports'.

   T. Maekawa communicated again about his episode that

   when he was a freshman at a company his boss guided him

   uniquely to write a report everyday; first a line,

   then a few lines, and finally a page.


Best wishes,

Toru Nakagawa
