Police questioning is police measure for acquiring information or inquiring an identification without questionee's will in order to accomplish the goal under the Police Act. However, like spear and shield, it has its own inherent limits between both sides of public power and human right and has stirred an hot issue in our society for longtime. The core problem is whether policeman can force a questionee stop when the questionee refuses policeman's stop requirement, the first step for police questioning. Some opinions argue that police questioning has somewhat effects on crime prevention and suspect arrest but people still have inconvenience and refusal from experiences of reckless police questioning in the past. Because of this, the police needs to recover people's trust on police questioning. In order to do so, in case of police questioning, human right should be superior to crime prevention or suspect arrest. This is the time's call. So when there is a police questioning, policeman's exertion of it on the questionee who refuse it should be conducted under strict conditions.

Purpose: It is investigated whether the time division system can extend the field without diplopia for people with homonymous hemianopia. Methods: The time division system was manufactured by a modified mini fan and a black cardboard. In order to verify the effectiveness of the equipment, subjects with and without the equipment took part in the experiment to bisect the space and to recognize letters. Results: Subjects with and without the equipment showed +8.91 and +18.14 degrees in the experiment to bisect the space. In the experiment reading the letters and numbers with the equipment, there were 9 percentage point increase in $4{\times}4$ charts and 15 percentage point increase in $6{\times}6$ charts. It turned out that there was a remarkable improvement for the worst group for reading the charts. Conclusions: The time division system is effective in the mobility and orientation for people with homonymous hemianopia.
