Abstract:
We created silver nanoparticles using silver nitrate and sodium alginate
through a method of mixing and heating the two solutions. The nanoparticles
were confirmed by spectrographs and electron micrograph investigations. They
proved to be very effective inhibiting the growth of E.Coli when embedded in
agar.

Students’ Attitudes Toward Tap Water: The Case of Seoul City’s Arisu
by
H.S. Yoo
Abstract
Recent years have witnessed vast numbers of people paying closer attention to various health issues. Young consumers are beginning to shun fast-food products in favor of healthy alternatives such as organic food and MSG-free products. This trend may also apply to drinking water. Producers of bottled water tempt consumers through attractive advertising and promotional campaigns, and as a result, bottled water has become the product of choice among consumers across the world. However, tap water can be just as pure and safe as any bottled water, and it is generally free. Therefore, consumers’ preference for bottled water may be a poor choice. In addition, adults’ drinking habits may be different from those of young individuals. However, previous studies have focused mainly on adult consumers of drinking water. In this regard, this study examines students’ attitudes toward tap water and investigates whether there is any gender difference in these attitudes by considering the case of Arisu, a brand of tap water supplied by the Seoul metropolitan government of Korea. According to the results, there was no significant gender difference in attitudes toward Arisu. In addition, both male and female respondents preferred bottled water to tap water. Further, both male and female respondents identified the smell of tap water was the most important factor influencing their decision to avoid tap water. The results have important practical implications for the Seoul metropolitan government as well as for other local governments wishing to promote their tap water.

The “Despicable” Chinese
Zhenlin Kan
Headlines like “Litter Everywhere After Their Departure” and “Unwelcome Tourists From China” raise the question of whether Chinese people are internationally regarded as less civilized than others. But are they?
It is difficult to not notice the deluge of negative opinions toward one specific population, so this warrants a closer look at this issue.
On March 1, 2016, a young Chinese female passenger was insulted aboard Virgin Atlantic Airways Flight VS250 from London to Shanghai. In addition to facing discriminatory verbal abuse from a white passenger, she was also threatened by the chief flight attendant. She was completely neglected during the whole flight (except for a Chinese attendant who was warned not to talk about the incident during the flight). Enraged, the victim narrated her experience on the Internet and wrote a scathing letter to the airline.
Noteworthy is that, unlike many Chinese people who are used to receiving unfair treatment initially caused by some rude Chinese tourists and prefer to tolerate such treatment instead of becoming entangled in some conflict, the woman was courageous enough to stand up and defend her dignity. As a result, her actions galvanized millions of internet users in China into seeking justice, attracted international attention, and utimately forced Virgin Atlantic Airways to issue a formal apology.
A week later, on March 8, a dozen “Chinese” tourists were caught swimming nude at a famous public beach in Thailand. A photo taken by a local resident spread quickly online, stimulating a diverse range of inflammatory comments about Chinese tourists. However, it was later learned that the tourists were Japanese. This raises the question of whether Chinese people are more likely than other ethnic groups to be wrongfully treated and accused.
The answer may be quite simple: After the photo was released online, no Chinese responded. None called for an investigation. It would appear that to many Chinese people, such events do not really matter as long as they have some personal impact. That is, it is not worth it to get involved and be bruised in the process. This may motivate many to remain aloof to others. Defend no one, and pay no attention to others’ conduct. No wonder things have been getting worse.
Are people of various ethnic backgrounds really different? I strongly doubt it. Then the answer calls for Chinese people to voice their concerns more actively. Without this voice, Chinese people are likely to witness their situation worsen.
Abstract
This thought experiment addresses loss of volume that occurs when a three-dimensional object is
contracted due to relativistic processes. Specifically we investigate the dependence of contraction
due to orientation relative to direction of motion. Length contraction states that relative constant
velocity will lead to a shortened distance in the direction of motion, when viewed from a
separate inertial reference frame. When applied to two dimensional shapes, this results in a
reduced area. The problem initially focuses on a square pyramid with the height perpendicular to
the direction of motion. Using geometry, it is found that the area of the base is invariant under
rotation. The problem is then expanded to general shapes. Any shape can be approximated by
inscribing circles within the perimeter, coming arbitrarily close to the shape’s actual area. Since
circles are fundamentally invariant under rotation, the change in area of a circle is independent of
orientation. This argument is used to postulate that any two dimensional shape, when contracted
in one direction, will have a reduced area that is invariant under rotation. Therefore the
contracted area and subsequent reduced volume depend only on the Lorentz factor γ, and not on
relative orientation of the object. A key next step is to determine if this can be extrapolated to
three dimensions, using spheres instead of circles.
