Lighting in the tunnel makes for safe driving of cars taking into account of change in perception arisen in the sight of drivers of cars entering into and passing tunnel, drivers' mental reaction and unique circumstances of a tunnel. There are many variables to satisfy safe driving in the tunnel. Since tunnels are mostly located in the mountainous area and illumination at the approach part differs largely depending on the surrounding circumstances, a standard different from that of common lighting is applied. An accidentin the tunnel, which involves same danger as in underground, may lead to a large mishap. Therefore, control by sensors inside and outside of tunnel ensures prevention of an accident through control of illumination at the approach part and inside of tunnel. It is very important in the aspect of saving energy since such control is available to reduce depreciation factor resulted from early excessive intensity of illumination.

Researches on the danger of nuclear power generation, the foundation of the development of national industry and one of the energy sources, as perceived by ordinary citizens, are very important to social acceptance of nuclear power generation. Accordingly, this study intends to understand how ordinary citizens perceive the social risk of nuclear power generation and radiation, and their misconceptions, and to propose ways to improve such perceptions. To achieve these goals, this study analyzed the perceptions of 251 ordinary citizens. The analysis showed that ordinary citizens have vague anxiety and suspicion about the safety of nuclear power generation, and little trust in government-affiliated organizations. The younger they were, the more influential they thought corporations and industries were. The result of this study suggests that the misconceptions of ordinary citizens should be corrected by professors and scientists in university research institutions they trust the most, and their intrinsic perceptions should be changed accordingly.

This study was conducted in order to compare weight control behaviors, eating disorder risk, and depression in female adolescents according to dieting experience during the last year. The subjects were 707 students attending a girls' high school in Seoul, and all the information was collected by self-administered questionnaire. Eating disorder risk and depression were determined by using EAT-26 (Eating Attitude Test-26) and PHQ-9 (Patient Health Questionnaire-9), respectively. Data were compared between subjects with experience of dieting (320) and those without (387). More of the subjects with dieting experience were unsatisfied with their own body weights (76.9% vs. 44.2%, P<0.01) and weighed themselves frequently (P<0.01) compared to those without diet experience. EAT-26 ($11.63{\pm}8.3$ vs. $5.99{\pm}4.7$, P<0.01) and PHQ-9 scores ($7.05{\pm}4.6$ vs. $6.00{\pm}4.4$, P<0.01) were higher in subjects with dieting experience compared to their counterparts. Therefore, we concluded that dieting is associated with several undesirable psychological aspects such as eating disorder risk and depression in adolescent girls, and thus providing proper education is urgently needed to emphasizing importance of healthy weight and the danger of unnecessary dieting.
