I met Dean Dr Sri Nurdiati, Dr Hamim (Vice Dean), Dr Kgs Dahlan (IPB Campus Dramaga) and Dr Sony Hartono Wijaya (Computer Science Dept). Shirota presented our joint research with UI (National University of Indonesia) Lambaga Demografi (Institute for Population Research) in 2019. In addition, I explained the recent Financal Analysis methods by machine learning approaches or so. Among them, Dean was interested in shape analysis and we discussed the possibility of the joint data analysis by shape analysis the next time I will visit IPB. Then I met Dr. Amrozi of Faculty of Veterinary Medicine to discuss statistical education. Then we discussed the effective learning materials of BASIC statistics and introduced my visual teaching materials for statistics.
・On February 27, 2020 I visited Dr Ruri in Lambaga Demografi, Indonesia University. Dr Ruri made the presentation to explain the collected data via WEB survey on the Female Participation Indicator in Asian Countries (in this case, an opinion survey in Indonesia). We discussed the contents of the data.

・On 1st August 2019, Prof Shirota, Prof Takako Hashimoto (previous IEEE Women Engineering Chairperson, Vice-president of Chiba Univ. of Commerce), and Prof Basabi Chakraborty (Iwate Prefectural Univ.) visited University of Indonesia. First, we conducted in Faculty of Economics and Business the workshop titled "Workshop on Development of 3D Graphics of Lagrange Multiplier Method". The attendance is lectures of the faculty members. The purpose of the workshop is that they learn the development way of economics math teaching materials using Mathematica. Then both knowledge of economics math and programming skills are required. About 10 lectures worked hard to learn the programming. The presentation materials is here. 
・Secondly, we held the mini-workshop titled "Three Methods for Demographic Data Analysis" in Lenbaga Demografi (Population Research Centre). The contents were (1) Women employment exit in Indonesia -analysis using longitudinal data, (2) Analysis of Mortality Rate using Machine Learning Regression - Scikit-Learn, and (3) Time Series Change Analysis of TFRs in Indonesia usinf Random Matrix Theory. Lambaga Demograpfi members including the previous Director of LD, Prof. Dr. Sri Moertiningsih Adioetomo. From Dr Sri, we could be given many wonderful advices. In the night, we met Prof Riri who read our paper in QIR 2019 in July.

・During my stay in Feb. I, Prof Riri, Dr Ruri, and Dr Diana had many discussions on our research concerning the total fertility rate decline in Indonesia. 
・On 27th Jan, I went to Lambaga Demografi, UI to have discussions. We had a long discussion with
our population related researches with Dr Turro, Dr Diana, Dr Ruri, and Dr Salut (Dr Salahudin Muhidin)
who is now in Macquarie University in Sydney. Owing to Dr Ruri's helps, I could start analyzing
the Indonesia Family Life Survey data which is our main target big data. I reported them that my
Machine Learning environment started running well this month.
・On 28th Jan, I met Prof Riri as usual for discussions.  ・On 29th Jan, I did a courtesy call to Dr Amrozi at IPB (Bogor Agricultual University) who is THE horse doctor around Bogor. I asked him to give us comments from a biological viewpoint after we finished our TFR research. 
・On 30th Jan, I paid my complimetns to Dr Teguh Dartanto who is the chair of Department of
