The purpose of this study was to examine differences between male and female in blood oxygen saturation due to 93% oxygen administration of the three levels (1L/min, 3L/min, 5L/min). Ten healthy male ($25.0{\pm}1.8$ years) and ten female ($23.7{\pm}1.9$ years) college students were selected as the subjects for this study. The experiment consisted of three runs, i.e., the three levels of 93% oxygen administration, respectively. The each run consisted of three phases, i.e., Rest 1 (5 min), Hyperoxia (10 min), and Rest 2 (5 min). Blood oxygen saturation were measured throughout the three phases. By increasing the supply rate of highly concentrated oxygen, rising rate of blood oxygen saturation was increased. Blood oxygen saturation of female was higher than male regardless of supply rate of highly concentrated oxygen and phases.

Recently, it has been emphasized that more girls should be able to contribute to society in the engineering field. However, there is little research for understanding the psychological characteristics of female engineering students. We first must understand their capabilities in order to take advantage of the strengths of female engineering college students. Based on this understanding, it is necessary to provide future educational interventions for them. Therefore, the purpose of this study was to investigate the gender differences in creativity in engineering education. Additionally, we wanted to know whether the differences were domain-specific or domain-general differences. For this, we targeted 351 engineering students in Busan and Daegu. An integrated creativity test and engineering creativity test were carried out. It was found that female engineering students had lower scores on both the integrated creativity and engineering creativity tests than male students. These results suggest that we should develop and apply appropriate strategies to enhance the creativity of female students in engineering education.

This study has been carried out to obtain information regarding to the food habits including health-related behaviors, the nutrition knowledge and the satisfaction on the dormitory food service. The subjects of this study were 758 college students (580 male and 178 female) residing in the dormitory in Ulsan. The data were obtained through questionnaire and interview, and were analyzed using the SPSS package program. the results of this study are as follows: The average age of the subjects was $20.7\pm2.3$ years old. The average height and weight of male were $175.2\pm5.0\;cm\;and\;69.4\pm9.6\;kg$, respectively. Those of female were $162.6\pm4.1\;cm\;and\;51.8\pm5.9\;kg$, respectively. The BMI value of male was $22.6\pm0.1$ which ranged within normal level, but that of female was $19.6\pm0.2$ which ranged underweight level. In the case of food habits, $26.0\%$ of total subjects always skipped a meal (especially breakfast). The main reasons for skipping meals were no time to eat, no appetite, and weight control. Most of subjects ($69.3\%$) have usually eaten snack after dinner, their most favorite food was noodle (ramen), and the next was pizza. With regard to the health care, there was a significant difference between male and female respect to smoking (p<0.001), drinking (p<0.01) and exercise level (p< 0.001). The mean food habit score of the subjects was $59.9\pm11.1$. Male students had a higher food habit score than female students (male: $60.6\pm10.9$, female: $57.7\pm11.4$), and the group residing longer period had a higher food habit score than the one residing shorter period. Average nutrition knowledge score of subjects was $7.8\pm1.8$. Gender, residing periods, monthly pocket money influenced on the nutrition knowledge score. Female had a higher score than that of male (P<0.001), and the group residing longer period had a higher score than the one residing shorter period (p<0.01), and the group who had more monthly pocket money had a higher score than the one who had less. No significant correlation was found between food habit score and nutrition knowledge score. In the case of dormitory food service, the total subjects showed high satisfaction scores for the sanitation and the atmosphere, while low scores for the menu and the quality of food service. This study may provide basic information on the eating habits and health-related behaviors of college students in dormitory. However, further studies and nutrition counseling are needed to improve food habits and nutrition knowledge.

This study analyzes the characteristics of good impression using speech manipulation scripts and investigates the characteristics of preferred speech voice. Fourty male and female college students participated in this study. They have been exposed to the Gyeongsang dialect spoken by their friends and family for more than 15 years. Two sample voices(1 male and 1 female), considered as giving good impression, were subject to voice analysis. Two students were asked to read the sample paragraph of 'Walking' and their voice samples were analyzed through Praat. The collected speech data were manipulated into 4 different sets by changing pitch level, degree of loudness and speech rate. First, both men and women received good impression more from pitch-lowered sound than from the original one. Second, men tended to receive good impression more from slightly louder voice than from the natural-pitched one. Third, it was shown that men often felt more drowned to a voice at slightly faster speech rate than at the original speech rate. Overall, both male and female listeners favored lower pitch over the original pitch. Men tended to prefer louder voice sound while women preferred less loud one. Men received better impression at a lower speech rate but women at a faster speech rate.

The purpose of this study was to present new data on the timing and sequence of permanent teeth emergence and to compare these findings with the results of earlier studies. The dental examinations had been performed to E-elementary school students, who visited the Yonsei University Dental Hospital between 1998 and 2005; 1,307 boys and 1,312 girls with the age ranging from 6 to 12 years old. The followings were concluded. 1. Eruption time of the maxillary permanent teeth is as follows. It was 6.81 years in male and 6.73 years in female for the central incisor, 7.78 years in male and 7.65 years in female for the lateral incisor, 10.48 years in male and 9.92 years in female for the canine, 9.76 years in male and 9.63 years in female for the first premolar, 10.66 years in male and 10.49 years in female for the second premolar, 6.39 years in male and 6.26 years in female for the first permanent molar, and 12.13 years in male and 12.03 years in female for the second permanent molar. 2. Eruption time of the mandibular permanent teeth is as follows. The central incisor could not be determined in this study, but it is assumed to erupt before the age of 6.08. In the mandible, eruption time was 6.78 years in male and 6.65 years in female for the lateral incisor, 9.76 years in male and 9.05 years in female for the canine, 9.82 years in male and 9.59 years in female for the first premolar, 10.67 years in male and 10.52 years in female for the second premolar, 6.22 years in male and 6.12 years in female for the first permanent molar, and 11.58 years in male and 11.14 years in female for the second permanent molar. 3. The eruption sequence is as follows. In the maxilla, the first permanent molar erupted first, followed by the central incisor, the lateral incisor, the first premolar, the canine, the second premolar, and the second permanent molar. In the mandible, the central incisor erupted first, followed by the first permanent molar, the lateral incisor, the canine, the first premolar, the second premolar, and the second permanent molar. 4. Tooth eruption occurred earlier in female compared to male by average of 0.19 year in the maxilla and 0.29 year in the mandible. 5. In both male and female, the hiatus (interval of rest) occurred between the emergence of lateral incisor and first premolar in the maxilla while it was observed between the lateral incisor and canine in the mandible. Male had a hiatus of 1.98 years in the maxilla and 2.90 years in the mandible, while the female's were 1.98 years and 2.40 years, respectively.

Objectives : To evaluate the degree of adolescent internet addiction, and investigate its relationship to the general characteristics, internet environments, and contents, especially the stress measured by the psychosocial wellbeing index-short form(PWI-SF). Methods : The data was obtained from self-administered questionnaires from 886 11th grade urban area students. The questionnaires consisted of general characteristics, internet user's environments, frequencies by internet contents, internet addiction test and PWI-SF. Results : The possible rate of internet use at home was 95.1%, and the area of most internet use was the home. The frequencies of internet game and porno site use were higher in males, with web searching and community uses higher in females. The total mean of internet addiction score was 56.8, and was higher for male than for female students. From multiple regression, as analyzed by the internet addiction score as a dependent variable, on-line friends, internet use times, years of internet use, frequencies of internet game, & porno site use, and PWI-SF scores were significant in male. Internet use times, the frequencies of internet game, chatting, community use, and PWI-SF score were significant in female. Four PWI-SF subscales(social role & self reliability, depression, general health & vitality, and sleep disturbance & anxiety) and internet addiction were significantly correlated in both male and female students, with depression having the most correlation. Conclusion : The results of this study suggest that intervention should be provided to prevent internal addiction, especially for coping with stress in Korean teenage students.
