Indoor air quality tends to be the dominant contributor to personal exposure, because most people spend over 80% of their time indoors. In this study, indoor and outdoor NO2 concentrations were measured simultaneously with personal exposures of 30 university students in weekday and weekend in Daegu, Korea. House characteristics and subject's activity pattern were used to determine the effects on personal exposure. Since university students spent most of their times indoor, their NO2 exposure was associated with indoor NO2 level during both weekday and weekend in spite of different time activity. Using a time-weighted average model, NO2 exposures of university students were estimated by NO2 measurements in indoor home, indoor school, and outdoor home. In conclusion, major personal exposure to NO2 resulted from air quality of indoor environment at house.

The purpose of this study is to examine the effects of English oral presentation strategy training (OPST) in EFL contexts. For this study, eight university students of 4 high and 4 low proficiency level are selected. The participants were provided with an OPST over 5 weeks including 8 times of training. During the OPST, the participants learned 25 strategy, 17 verbal and 8 non-verbal strategies. The verbal strategies were again divided into two parts: general verbal strategies and genre specific strategies. For the validity of the present study a “triangulation” was achieved through the use of video recording, classroom observation, questionnaire, in-depth interview, and the native English speaker’s evaluation. The results of the study demonstrated that the participants showed some improvement in the use of presentation strategies, especially organizational and verbal components of the strategies rather than nonlinguistic components. The proficiency level of the participants had an effect on the frequency of use of strategies after the OPST. Overall, the OPST was found to have positive effects on the participants’ attitude toward English oral presentations. On the basis of the results of the study, some teaching implications for improving presentation skills in university EAP contexts are provided.

This study attempts to examine the existence of foreign language anxiety in e-Learning situations, and then identify relationships between the anxiety and learner background factors. A total of 162 EFL learners participated in the survey. Their anxiety was measured by the e-Foreign Language Classroom Anxiety Scale (e-FLCAS). The results suggest that foreign language learners do indeed experience anxiety in e-Learning classrooms. A majority of the participants acknowledged having experienced specific kinds of anxiety in cyber classes: worry over e-Learning education, online test anxiety, learning style conflicts, and apprehension of native teachers. In addition, e-Learning anxiety was found to be significantly related to three background factors (gender, academic backgrounds, and English proficiency). The results also provide a potential explanation of anxiety-producing contexts in cyber classrooms, the sources of anxiety, and coping strategies that students use to lower their anxiety.

The purpose of this paper is to investigate English education experts’ current general views on the college English curriculum at Korean provincial universities and elicit their consensus of opinion on the distinctive characteristics of the curriculum. For that purpose, two rounds of the delphi survey were presented to forty experts, with thirty one experts’ responses in the first round and nineteen in the second. Based on their responses, the following characteristics of the Korean college English curriculum for provincial universities were deduced as a consensus of opinion: the curriculum is supposed to be more intensive, practical, proficiency-based, and university-specific than the curriculum for the universities in the Metropolitan area; it is supposed to be English for Specific Purposes (ESP) rather than English for General Purposes (EGP) in order to promote the future career of the individual provincial university students and the competitiveness of the provincial universities themselves.

Thermal response of Korean college students was investigated in a thermal environmental chamber during summer season. Eight thermal conditions combined with four air temperatures (24, 26, 28, 30℃) and three relative humidities (40, 60, 80%) were selected. Subjects of seven females and seven males were questioned in the chamber for three hours, where thermal and comfort sensations were surveyed every fifteen minutes. During the period of thermal response experiment, four thermal parameters of air temperature, relative humidity, air velocity, and globe temperature were monitored in the test chamber. The repeatability and temporal variation of thermal response were discussed. The thermal sensation vote (TSV) of females is in good agreement with the predicted mean vote (PMV) calculated from the thermal parameters and human parameters. However, the TSV of male shows a slight discrepancy with the PMV. The neutral points of both female and male are very close to 0.18 of PMV, indicating that college-age Korean like to a slight warm environment compared with Western people. The thermal sensation vote of subjects is well correlated with the comfort sensation vote.
