In an online survey of 889 university students in March regarding the Kang Ho-soon case, some 46 percent of female respondents, or 260 people, said they try to go home early, the online job portal Albamon said.
About 20 percent of women said they grew more interested in self-defense. Nearly 94 percent of the total participants said since the serial killing incident, they have felt scared upon encountering someone at night.
In a related move, the sale of self-defense products from January to March soared 80 percent compared to the same period last year, according to the country`s major internet shopping website Interpark.
In the period leading up to March 14, which Koreans celebrate as "White Day" by giving their loved ones candy and presents, gift sets containing self-defense items were popular on online shopping sites.
Internet retailer Auction said it has sold some 4,500 units of those gift sets in one week in early March. Similarly, Gmarket said the sale of self-defense products in early March tripled compared to the same period last year.
Interpark said the best-sellers are gas sprays in lipstick cases, accounting for about 70 percent of their total sales, as they are discreet and easy to carry around. Other popular products include whistles and pepper sprays that do not require permission.
A manufacturer of self-defense items said its sales doubled shortly after the Kang Ho-soon incident, but has steadily decreased more recently.
The widespread anxiety has also led mobile phone manufacturers to unveil products designed to sound an alarm when activated by the user.
In late March, Samsung Electronics unveiled the Anycall SPH-W7100 phone with a loud, 100-decibel alarm which can be activated by pulling a ring connected to the top of the handset in case of emergency. This "Bodyguard Phone" also has a GPS function to transmit the location of the user in case the alarm is de-activated forcibly and sends SOS messages to the user`s parents.
Samsung`s Haptic Pop SCH-W750 phone also provides safety features, such as easy SOS button options to set off a fake incoming call ring-tone and an alarm.
