Matsuyama_WET 2018

Last weekend, I joined in a conference – Water and Environment Technology 2018 – in Matsuyama, Ehime. It has been a great experience where I met many international students, professors and specialists in environment field. This conference was very well-organized and successful. I fully enjoyed the event with so many interesting presentations and discussions on various topics. Especially, I had a chance to have a presentation and show a poster about my research topic. I would like to take this chance to learn more experiences for my future job. After the conference, there was a party where I could make new friends and try some special foods, particularly Ehime University’s Beer that’s so delicious.
On the second day, I went to The Matsuyama Castle which is one of the most complex and interesting castles in Japan. From there, I could see a bird’s eye view of Matsuyama and the Seto Inland Sea. Although the castle is located on the hilltop, a ropeway and a chairlift make it easily accessible. Riding a single-chairlift was very interesting that I have never tried it before. I came back Nagasaki by ship and express trains. During that time, I just enjoyed the beautiful views of Japan through the window. I hope I will have more chances to discover many famous places in Japan.
After all, I would like to say thanks to Prof. Fujioka for giving me this opportunity. I have benefited too much from this trip and it become my unforgettable memories.

Cultural Diversity and its role in Adapting to Studies in Japan.


The ability to successfully learn with students who come from a culture or cultures other than our own; entails developing certain personal and interpersonal awareness and sensitivities, understanding certain bodies of cultural knowledge, and mastering a set of skills that, taken together, underlie effective cross-cultural learning and culturally responsive awareness.

The matrix of functions on the role of enabling cultural diversity can be multi-dimensional, involving several key stakeholders, ranging from teachers, students and the University support staff. For example, teachers must become more fully student-centered and inclusive of the voices and experiences of the students while students must learn the truth about history even if it may be painful or produce controversy. Every student must be prepared to competently participate in an increasingly intercultural society. When students learn to recognize and appreciate the differences they see in others, they learn more about themselves.

One of the key practices to building cultural integration in Japanese Universities is anchored on the pillar of building teams and working in groups. For the case of Nagasaki University, in the water and Environmental Engineering Master course; a mixture of students coming from Uganda, Japan, Kenya, Thailand, Senegal, Zimbabwe, Vietnam, Peru and Korea are evenly distributed to each group. When students from diverse backgrounds and experiences work together, the differences among them enrich the group discussion and overall experience for the group.

It is also worthy to mention that the individual skills that come with each of the group members helps to supplement and compliment on the overall group kills and serves to build the confidence of group members. For example, some of the students are very good at Japanese while others are good at English. Continued interactions among students has helped the non-Japanese natives to ably adapt to living in Japan, where Japanese is the most commonly preferred language of communication. On the other hand, the Japanese students get a chance to practice their English language skills while communicating with the English-speaking students. 

How about joining a students’ club? Oh wow, this another amazing activity to join when in Nagasaki University. So many clubs namely; dancing club, sports club, art and design club; are open to new entrants. These are stress relieving moments to share and learn from new students.  Am getting good at Zumba dance courtesy of the dancing club. It’s quite different from our way of dancing back home in Uganda, but it was worth the try. 

The University community of Nagasaki is more involved and supportive through their Liaison centre for international students. The diverse cultures in the students’ community are valued and celebrated through get together parties, sports, motivational talks, club gatherings and several other activities that involve outreach programmes to high school students in Nagasaki.

I would therefore advise everyone to embrace cultural diversity with positivity because the fruits are more. The students can become unified by embracing the differences and thus making their life in Japan memorable.

Holiday trip_5/2018

My holiday trip, two week ago, I had the opportunity to visit Iojima Island with my friends. At that time, it was Golden Week of Japan – the longest vacation period of the year- so we had free time for traveling. We were looking forward to the trip because this was the first time we went there. The boat trip from Nagasaki to this Island was very interesting. It only took 20 minutes and we could see nice views of the cityscape from the sea. When we got off the boat, there was a map on the signboard showing three routes around the island. We walked along the beach which was a strange place – lovely sand and calm blue sea. The beach was clean and beautiful. After that, we went up the hill to the lighthouse and took many photos from there. There are many paths through the forest with cool atmosphere, beautiful flower and tasty fruits. The best time to visit this region is spring and it seems to be a good place to relax. I will come back here once again in the future.

2018 Water Research foundation conference, Atlanta, GA (May 6-8)

At first sight I want to thank Abe I initiative scholarship for giving opportunity to participate in the water reuse conference held in Atlanta, GA. I also want to thank my supervisor Mr. Takahiro Fujioka  who spared no effort to expose me in this environment full of water sciences experts. This trip in USA was very exciting for me cos it was my first one in this continent. It was a new experience for me as a student who is interested in water area. As I expected I found very kind and humble people who shared their knowledge and experience with me. The water research conference has united many workers from the US public and private sector. Some foreign researchers were  also part of the even. All the presentations were mostly about DPR (Direct Potable Reuse) and IPR (Indirect Potable Reuse). Therefore, during three days from 08:30 am to 5 pm participants were sharing their experience and research about water treatment. The first workshop which I was part of focused on waste water treatment for irrigation purposes. The results presented in this workshop were very concluding in term cost and environment protection. It was proved that when the populations are well informed they will agree to use products from irrigation by treated wastewater. I was also attracted by a post which was talking about waste water treatment for drinking purpose. This study was done in California and based on three steps filtration Microfiltration-Reverse osmosis and UV treatment. In this world where water resource is becoming rare this process could be an alternative. Thus, another presentation captured my attention. It was one did by Sense Fujioka Takahiro which about modifying RO membrane for N-nitrosodimethylamine rejection improvement. Therefore, by heating the membrane he succeeds to get a high removal of the carcinogenic molecule. However further researches should be done to limit the flux decreasing due to the heat. During the three days of the conference I hanged out after sessions in order to discover Atlanta city. I really like the town. I even met an African guy who speaks my mother tongue. He shared some information with me about life in Atlanta city. Finally, I can say that this trip was an amazing experience for me as a student in water and environment but also as a tourist.

Water Reuse Conference Held at Peachtree in Atlanta, USA


I was privileged to be among the participants of the water reuse conference that was held at Peachtree hotel in Atlanta, USA from May 6th – 8th, 2018. The Research Conference is designed to help communities prepare for the future with a comprehensive program offering innovative approaches and creative solutions for managing our water resources.
The conference is aimed at furthering the development of reuse water qualities that are fit-for-purpose and within the regulated requirements for water quality. It is worthy to mention that the latest research addressing the challenges of integrated water management and reuse are presented for discussion and deliberations. The event provides for opportunities to share knowledge regarding water reuse approaches and applications in different States in the USA, to build trust and further grow water reuse projects.
As students, studying membrane technology for water treatment, the opportunity was so benefiting that it provided further insight into a wide range of membrane technologies which are applicable in water treatment. But gladly to mention, it was a golden opportunity to meet with the most tested and top of the notch researchers in membrane science technology. It was so humbling to share a moment with Harold Fravel, Jr, the executive director of the American Membrane Technology Association.  His vast knowledge of membranes is just a click-off head, another moving encyclopaedia of knowledge.
The world is seeking for innovative and better methods of solving the recurrent water scarcity issue. One option is sewer mining for reuse, but the big question arises “Won’t the new water cause more health problems”. Researchers are still intrigued by this concern, but most especially with the removal of infectious pathogens, NMDAs and CECs from water for reuse. Quite a few promising research presentations were made on this problem.  Noticeably, was the presentation on modification of RO membranes for removal of NMDAs by Prof.Takahiro Fujioka. He uses the technique of increased feedwater temperature to improve the removal efficiency of RO membranes for NMDAs. However, I can ably say that this area is still very open to further research, and therefore a new avenue for future students.
How about removal of viruses from water? Norovirus is one of the key viruses to be taken keen of during sewer mining. The virus is very infectious even in trace amounts! Quite astonishing. Research is therefore needed to develop a technology which can detect both dead and live pathogens as opposed to the present methods which depend on total counts. Removal of pathogens and monitoring of wastewater treatment plants effluents for water quality is key in water reuse. New research is therefore taking the twist to develop a technology for total removal and detection of pathogens in water.
In summary, the quality of the water for reuse purposes should be taken with utmost integrity and care. New research in improved removal and detection of NMDAs, CECs, and pathogens is very paramount but still in the initial stages of development. This is therefore a bank for new research topics for the upcoming researchers.
