Assistant Professor → Associate Professor in Japanese University

I got promoted as Associate Professor on April 1. Alhamdulillah!

 

Of course it was hard work, blood, sweat and tears, no shortcut!

Working in a Japanese university is extremely hard. We need to do all the work - literally all - from sweeping and cleaning the lab, making coffee when guests are coming, preparing for a bunch of classes, teaching, evaluating, marking the score, taking care of students, being the person in charge for department, faculty, and university level of something (for example, managing department's SNS, department's marketing, making pamphlet, and so on and so on - the list can go on), being active in academic life outside campus, and lastly, research. Yes, research! Research is the last thing that you can do in the university that I work. 

Let's talk about this later, now not thou.

To get promoted to be Associate Professor in this university, here are the requirements:

1. PhD holder (Currently, job applications for lecturers are only for PhDs, but lecturers from the old days sometimes still have no PhD)
2. Must have experience guiding the thesis of 4th year students (The criteria for each department is different, in my department, more than 20 students) 
3. Write an essay about the targets to be achieved in the new position and career design as a lecturer
4. In the last 5 years must publish at least 3 international journals or 4 local journals as first author
5. Points from teaching experience (criteria for each department are different extremely difficult to explain, so skip! But as a hint there are criteria for the number of classes, the number of students, class evaluation by students)
6. Points from academics (number of journals published, impact factor, number of proceedings, number of presentations at conferences, number of academic awards, number of patents, number of books). Point weight is different for first author and non-first author
7. Points from non-academics (helping association as for example secretary, being chairperson at conference, being an adviser in a student club, being an adviser in company)
8. Points from research grants (where have you gotten research grants, how many are principal investigators, how many are research members)
9. Points from being in charge of department activities (being in charge of any role in department, faculty and university activities) 
10. Print all the documents (at least 4 copy), explain and evaluated by your supervisor (lab boss), department chair, dean and for university. Then after passing through, the documents will be checked again and again by campus' Human Resources Committee (mostly Professors) to be recommended to the university boss (Rector and Chairman of the Board of Directors of a school foundation)

In Japan, you don't have to get approval from the Ministry of Education and Culture or the Japanese Higher Education (I heard in several countries you must get approval from the ministry...). All of this is regulated within the university/foundation, so it is the university/foundation that determines whether you become a professor. The university only have to report to the Ministry of Education and Culture and attach all the documents.

Muslim travelers in Japan prioritize prayer room when choosing place to dine out!

Driving factor of Muslim travelers in Japan when choosing a place for dining out?

 

Together with Ahmad Mahbubi Mufti , we tried to clarify factors influencing Muslim travelers when dining out in Japan.

 

1. What’s the priority for Muslim travelers when choosing a place for dining out?

> 70% of Muslim travelers in Japan prioritized prayer room availability more than halal-certified food (although in the last decade we experienced halal boom). Only 20% of Muslim travelers were prioritizing halal-certified food. If you are making a business targeting Muslim travelers (maybe after this COVID-19 pandemic end), then you should consider providing a prayer room as your first service priority. If you still have the budget, time and energy, then gaining halal certification is also a good idea.

 

2. How much are Muslim travelers willing to pay for one serve of halal-certified food with a prayer room available?

> They were willing to pay for as much as 1.5 times higher than the average price of the same dish in Japan. E. g. Muslim travelers were willing to pay as much as 1,200 JPY for ramen (the average price of ramen in 2018 was 800 JPY). Their purchasing power is good, and they tend not to consider price when selecting their preferred place.

Simple basic spiral code implementation 2 with tolerance 0.1

Simple basic spiral code implementation 2 with tolerance 0.1

This is the sequel of the previous code implementation of spiral, that time I made a very simple archimedean spiral with the same step over. But sometime, we want more than a step over, a distance between each point of a spiral (tolerance).

Here is my code implementation in c.

         degree = theta*(180.0/M_PI);  
   
     }while( degree <= sizelimit );  
   
 }  

After running the code, it will print out the angle (radian), angle (degree), r of each point(interpreted as 1/curvature), x, y coordinate of each point, and the distance of each point.
The plotted spiral from the code in excel is as shown below.

Pretty simple right!

Browser Comparison: Firefox quantum vs Chrome

when working with a quite memory usage program, sometimes i also need to browse, that was when the idea of browser comparison came up
i usually have both of firefox and chrome just in case one of them have an issue or something, so let's compare them
yes, i know that microsoft also have its internet exploler or the newest microsoft edge, but as we know that both of them are out of the league, i didn't included them
for opera, i know opera is quite good as well but let's stick with firefox and chrome for righ now

quick snap result
chrome's speed is slightly faster (to be honest, the speed difference is not that significant to be written here)
but, firefox uses MUCH less memory (this is what i need)

both are the newest version up to this date (2018/06/18)
firefox quantum 60.0.2 (64 bit)
chrome 67.0.3396.87 (64 bit)

during the test i already open several applications which take 3.5gb
(clover 9 tabs, sticky notes windows native, power point, excel, outlook, cygwin)

then i opened firefox and chrome with 20 tabs of the same address

after opening firefox, the memory usage became 3.9gb, and close the firefox
but after opening chrome, the memory usage became 5.4gb!
i also opened both of firefox and chrome using the exact same 20 tabs, the memory usage became 6.0gb

for me, who consider less memory usage, firefox is the clear winner (for now)
let's see what the big g is going to do with the next chrome


----------------
test environment
i3-6100 3.7ghz
win 7 64 bit sp 1
8gb memory


ブラウザー比較：ファイヤーフォックスクァンタム　vs　クローム

結論
クロームの速度はファイヤーフォックスよりも少し上回るが(速度はここに記載するまでの差はない)、
ファイヤーフォックスはクロームよりも非常に少ないメモリを使用


2018/06/18時点で両ブラウザーとも最新のバージョン
ファイヤーフォックスクァンタム 60.0.2 (64 bit)
クローム 67.0.3396.87 (64 bit)

テストをしていた時には既に3.5gbのメモリを使用

ファイヤーフォックスを20タブ開いたら3.9gbのメモリ使用になり、ファイヤーフォックスを閉じて、クロームを同じ20タブを開いたらなんと5.4gbのメモリ使用になった！

現時点ではファイヤーフォックスクァンタムの勝ち
グーグルはファイヤーフォックスクァンタムに対し、今後何をするだろうかをお楽しみに
