    Artificial Intelligence (AI) has been developing rapidly last few years. This development influences the way to work in engineering deeply. However, the technologies of AI also have lots of ethical problems. In this paper, we argue that engineering ethics should deal with the ethical problems with AI. We focus on the following AI ethical problems. First, AI leads to a significant change in the way of our lives. Secondly, AI has the problems of product liability seriously. Thirdly, AI technology arises copyright problem or concern derived from the concept “strong AI”.

    Zengwen Reservoir was constructed from 1967 to 73. Part of construction fund (about 44 million dollars) was expended by Foreign Aid of Japan. Hatta Yoichi(1886-1942), engineer of Taiwan Governor-General planned this dam but the realization of the business was late for World War II. Nippon Koei, international consulting firm of Japan undertook this work. The president of the firm is Kubota Yutaka, who have had the experience built the dam over the world. Zengwen Reservoir received the criticism but achieved much economic result.

    Active learning is recently introduced to education field in Japan, and it stands in contrast to traditional modes of instruction in which students are passive recipients of knowledge from teachers. This article is concerned with mathematics class practice introducing group learning, which is one method of Active learning.

    Following Mexico and Mongolia, Thailand and Vietnum have recently started a new institution imitating KOSEN system in Japan. Kisarazu College is in charge of the support of education in Mongolia and Thailand. At the same time, they began to send students to KOSEN colleges to enter in the first school year, and to improve the education in junior-high schools. The author was asked to support these two activities as a Mathematics teacher. This short article summarizes the support and discusses possible further development.

    In this paper, I introduce a certain method of reflection. This method is describing the procedure toward the solution as if they explain it to their “virtual” friend. In recent years, it is not said that some students have enough abilities concerning general writing skills, including mathematical writing. Since the latter term in 2016 I have performed this method, and it is effective for them to obtain these abilities.

  • Current Situation and Issues of Active Learning at Kosen
    From the Results of the Organized Sessions at National Kosen Forum

    The authors moderated the organized sessions on active learning at National Kosen Forum in 2017 and 2018. We had guest speakers who are practicing active learning, exchanged information in a world cafe style, and conducted a survey at the end of each session. From the results of these sessions, the authors discovered that teachers who have little or no experience of active learning need practical examples and that teachers who have some practice need evaluation and verification method. At the present moment, kosen (technical college) teachers are required to concentrate efforts to develop active learning skills.

  • Maturity Evaluation of Large-fruited Tomato based on Chlorophyll Fluorescence Measurement
    Ken'ichi FUKUCHI, Yuko KAKAZU-OHNO

    We've reported on a fluorescence measurement method for nondestructive evaluation of maturity degree in cherry tomato fruits before1). In this study, we tried to evaluate the maturity of large-fruited tomatoes such as Home-Momotaro instead of cherry tomatoes. Like as the previous paper1), we used Fluorescence Maturity Index (FMI) for the evaluation, which had been defined as log (F685/F740). Here, F685 and F740 are the fluorescence intensity of 685 nm and 740 nm respectively. From the results of fluorescence spectra measurements in various conditions, we found that the fluorescence detection from 45 degree to 60 degree angle by the 620 nm excitation is the best. In addition, transmission spectra measurements in fruits and fluorescence imaging on the fruits cross section were made. Because the F685 is reabsorbed by the chlorophyll in fruits, the FMI has increased along with the decrease of chlorophyll by ripening. Moreover, if distance between the excitation light irradiation point and the fluorescence detection point is fixed, the FMI would be able to evaluate the maturity degree in fruits of various sizes by the same scale. The most important finding is that, the FMI has a possibility to be able to detect the changes of maturity at the mature green stage of tomato fruits that can't be judged from visual observation.

    We investigated a waste incineration plant and waste dumping site in Yangon, the biggest city of Myanmar. Because Yangon has been coming up against drastic urbanization especially since 2011 when democratization started followed by collapse of the military regime. This intense and rapid urbanization has influenced hygienic environment in Yangon and its suburbs. This paper discusses the hygienic conditions in Yangon through the investigation of the waste incineration plant and waste dumping site by focusing on waste management in Myanmar.
