Purpose: This study was designed to construct a structural model explaining alienation, depression, and suicidal thoughts in male and female adolescents. Method: Data was collected by questionnairs from 204 male and 208 female students selected randomly in high schools in K city Results: This study found that depression was significantly affected by alienation, and was indirectly affected through alienation by school attachment, peer relationships, and academic performance. Suicidal thoughts were greatly affected by depression, and were directly and indirectly influenced by alienation. It was confirmed that alienation turned out to be a important mediating variable, while it had a effect significant on depression and suicidal thoughts. Also there were significant differences in affecting factors among male and female students. Conclusion: Intervention strategies for preventing alienation, depression and suicidal thoughts should be different according to gender in addition, specific nursing intervention plans, including parent education and role training programs, fostering of humanistic and achievement-focused educational environment, peer support programs, and individual counselling, need to be developed and implemented to lessen a feeling of alienation from family and school.

Objectives: The objective of this study was to assess energy expenditure and metabolic cost (METs) of walking activities of college students and to compare treadmill based walking with self-selected hallway walking. Methods: Thirty subjects (mean age $23.4{\pm}1.6years$) completed eight walking activities. Five treadmill walking activities (TW2.4, TW3.2, TW4.0, TW4.8, TW5.6) were followed by three self-selected hallway walking activities, namely, walk as if you were walking and talking with a friend: HWL (leisurely), walk as if you were hurrying across the street at a cross-walk: HWB (brisk) and walk as fast as you can but do not run: HWF (fast) were performed by each subject. Energy expenditure was measured using a portable metabolic system and accelerometers. Results: Except for HWF (fast) activity, energy expenditures of all other walking activities measured were higher in male than in female subjects. The lowest energy expenditure and METs were observed in TW2.4 ($3.65{\pm}0.84kcal/min$ and $2.88{\pm}0.26METs$ in male), HWL (leisurely) ($2.85{\pm}0.70kcal/min$ and $3.20{\pm}0.57METs$ in female), and the highest rates were observed in HWF (fast) ($7.72{\pm}2.81kcal/min$, $5.84{\pm}1.84METs$ in male, $6.65{\pm}1.57kcal/min$, $7.13{\pm}0.68METs$ in female). Regarding the comparison of treadmill-based walking activities and self-selected walking, the energy expenditure of HWL (leisurely) was not significantly different from that of TW2.4. In case of male, no significant difference was observed between energy costs of HWB (brisk), HWF (fast) and TW5.6 activities, whereas in female, energy expenditures during HWB (brisk) and HWF (fast) were significantly different from that of TW5.6. Conclusions: In this study, we observed that energy expenditure from self-selected walking activities of college students was comparable with treadmill-based activities at specific speeds. Our results suggested that a practicing leisurely or brisk walking for a minimum of 150 minutes per week by both male and female college students enable them to meet recommendations from the Physical activity guide for Koreans.

This study was done to examine the sexual knowledge, attitudes, and behaviors of Korea college students and investigate the effects of sexual education programs on college students with respect to their sexual knowledge and sexual attitudes. For these objectives, a single 92 item sexual questionnaire was administered to 213 college students (113 in the experimental group and 100 in the control group) as a pretest one day before the experimental group participated in a sexual education program. Then a three week sexual education program was given to the experimental group and a posttest was administered to both groups day after the program. The findings from the pretest； 1) The main sources of sexual information were friends, Internet, books and magazines. College students in this study showed relatively high scores on their overall sexual knowledge but showed low scores on their knowledge of venereal disease and HIV/AIDS. Female students had a higher sexual knowledge of physiology, pregnancy and sexual abuse than male students. 2) The overall sexual attitudes of college students were subjective. They showed especially strong liberal attitudes to premarital intercourse, had few double standards and agreed on induced abortion. Male students showed a more liberal attitude to premarital intercourse and extramarital intercourse (X²＝50.679, p＜.001). Christian students showed the lowest rates of permissiveness for induced abortion than students of other religions. 3) 64.9％ of the subjects in this study had experience in intercourse. The gender and age of students did influence the experience rates of intercourse. Male students had much higher rates of intercourse than female students (X²＝13.565, p＜.001) and older students had higher experience rates of intercourse. 4) From the analysis of the relationship between sexual knowledge, attitudes and behaviors, this study revealed that sexual knowledge and sexual attitudes of college students have a correlation 6＝0.324, p＝0.000). Students' experience of intercourse did not influence their sexual knowledge scores, but did influence their sexual attitudes. Students who had experience of intercourse showed more liberal sexual attitudes than those students who did not (t＝2.677, p＜.050). And students who were exposed to sexual media such as pornography, sexual magazines, sexual books and the Internet, also showed more liberal sexual attitudes than those students who were not. The findings from the comparison of pretest and posttest ； 1. The sexual knowledge of the experimental group that participated in the sexual education program was significantly increased after the program compared to before the program (p＜.001). However the control group did not show any significant change in their sexual knowledge. 2. The sexual attitudes of the experimental group were also changed significantly becoming less liberal (p＜.001). The control group also showed significant change in their sexual attitudes, also becoming less liberal (p＜.001). Therefore, the sexual education program used in this study was effective in increasing college students' accurate sexual knowledge, but had little effect on their sexual attitudes.

The demographic characteristics of research examinees showed that male students were 122(44%) and female ones 155(56%), and teenagers 142 per age. The average monthly pocket money appeared that 96 students received more than 200,000(34.7%) and it was analyzed that 243(87.7%) resided in their homes. The research of fast-food choice factors resulted in the fact that female students who were easily influenced by their friends were 83, while males 57. And, mascom took influence on 40 female students and 20 male ones, besides other included 39 male and 30 female students. They most preferred hamburger and pizza(94) among the fast-food menus, and taste like seasame was most preferred among the characteristic factors of foods taste. And as a result of factor analysis of menu, Cronbach alpha coefficient Fc 2 of reliability appeared highest as 0.7694, next, Fc 3 as 0.6965, and Fc 1 lowest as 0.6403. The reliability among the specific items of this study may be regarded high. And the difference between groups according to gender appeared that Fc 1, Fc 2, and Fc 3 were significantly different at 5% level as a result of T-examination analysis and the distributed analysis of the average monthly pocket money resulted in the fact that the difference between groups appeared significantly at F3 below significant level of 0.05. The testing of the difference of reason why the fast-food is preferred according to frequency of use per week lead to Chi-square value of 41.399 with free degree of 12, so significant degree became 0.000. The zero hypothesis that the two variables are not independent each other is not reserved because it has a small value of signigicant degree below 0.05, and the permanent hypothesis is adopted.

PURPOSE: Application of an oscillating program for the lower extremities is an effective training method for increasing muscle strength. However, no oscillatory program has yet been identified to confirm the effectiveness of oscillation for balance ability and maximum muscle strength. We investigated the effects of an 8-week vibration exercise program on the maximum muscle strength and balance of the lower extremities. METHODS: Research subjects participating in the study were 22 male and female college students with no past history of diseases of the nervous or musculoskeletal systems. All subjects were randomly divided into two groups and performed their assigned experimental treatment 3 times a week over a period of 20 min for 8 weeks. Maximum strength of the quadriceps extension, flexion, and balance ability were measured using Biodex System 4 and Biodex balance systems. RESULTS: The 8-week oscillation program resulted in a significant increase in quadriceps extension and flexion strength in both male and female participants (p<.05). The balance ability also showed a significant improvement after the oscillation program (p<.05). The balance value was higher for male 17% than for female 21% (p<.05) participants. CONCLUSION: An 8-week oscillation program led to an increase in the strength of knee flexion and extension. The balance ability also improved significantly. This positive effect on balance ability was higher in female than in male subjects.

The purpose of this study was to examine the oral health awareness and oral health care of health-related and health-unrelated majors in an attempt to stress the importance of oral health education and boost the efficiency of oral health care. The subjects in this study were 363 college students. Out of the selected students, 174 were health-related majors, and 189 weren't. After a survey was conducted, the collected data were analyzed for the purpose of comparison, and the following findings were given: 1. Concerning daily mean toothbrushing frequency, the largest number of the male students who accounted for 55.2 percent brushed their teeth once a day on average, and the greatest number of the female students who represented 52.9 percent did that twice a day. As for the influence of their major, the largest group of the health-related majors who numbered 89(51.1%) brushed their teeth twice a day, and the greatest group of the health-unrelated majors who numbered 93(49.2%) did that once a day. The gaps between them were statistically significant(p<0.05). 2. As to the length of toothbrushing time by gender, it took more than two or three minutes for the largest groups of the male and female students that respectively numbered 96(76.8%) and 184(77.3%) to do toothbrushing(p<0.01). The greatest groups of the male and female students that respectively numbered 72(57.6%) and 183(76.9%) brushed their teeth after meals. 3. In regard to oral hygiene supplies, the largest groups of the health-related and health-unrelated majors that respectively numbered 78(44.8%) and 115(60.8%) had chewing gum and candy with them. As to the use of oral hygiene supplies, 99 health-related majors(56.9%) and 133 health-unrelated majors(70.4%) didn't put oral hygiene supplies to use. Thus, the use of oral hygiene supplies was statistically less common among the health-unrelated majors, and the gap between the two was significant(p<0.01). 4. As for health-related concern by gender, the largest group of the male students that numbered 56(44.8%) showed the most interest in preventing dental caries, and the greatest group of the female students that numbered 103(43.3%) were most concerned about tooth whitening. The gap between the male and female students was statistically significant(p<0.05), but the track of their major made no statistically significant difference to that. 5. Regarding the experience and awareness of scaling, the largest number of the students never got their teeth scaled regardless of gender and major, and the greatest group didn't care about scaling irrespective of gender and major, either, though they considered it advisable to do.

The purpose of this study was to examine the satisfaction level of patients with oral health care provided by a dental hospital, especially scaling, and their oral health behavior. The subjects in this study were 263 college students who were in their 20s and selected from among patients who visited D university dental hospital in Gangwon Province during the oral prophylaxis practice of dental hygiene sophomores and juniors. The findings of the study were as follows: 1. Whether the selected students had ever had their teeth scaled was checked, and those who had outnumbered the others who hadn't. The rates of the former and latter respectively stood at 61.2 percent and 38.8 percent. Regarding places where they got their teeth scaled, the majority of the students that represented 75.2 percent did that at dental clinics. By gender, 34.4 percent of the male students did that at schools, which were larger than 11.8 percent of the female students who did. 88.2 percent of the female students did that at dental clinics, which were larger than 65.5 percent of the male students who did. Gender made significant differences to that(x2=10.79, p<.01). 2. As for satisfaction level with scaling by gender, the male students (38.7%) who had no specific idea outnumbered the female students (26.5%) who did. The female students(57.4%) who felt no pain during scaling outnumbered the male students(55.9%) who did. Gender made a significant difference to their responses. (x2=6.38, p<.05). 3. Concerning the use of oral hygiene supplies, most of the students who represented 72.2 percent had never flossed their teeth, and as many as 86.3 percent had never used a tongue cleaner. But the gaps between them and the others were not statistically significant.

The purpose of this study is to analyze the subjective sensations and preference for spring/fall casual cotton shirt fabrics, and to assist in developing shirt fabrics that offer maximum comfort in wearing sensation. The subjects of this study were male and female college students who assessed the tactile sensation of seven types of spring/fall shirt fabrics available on the market: plain weave and rib weave made of cotton and that of cotton mixed fabrics. The subjects were university students between the ages of 20 to 23, who were residing in the city of Cheongju, Korea. The questionnaires related to the fabrics hand were evaluated using a nine point bi-polar scale of 9 descriptive terms. Mean, t-test, F-test and $X^2$ were used for data analysis. The fabric hand evaluation on the seven types of shirts showed a significant difference in all of the 9 descriptive terms. There were partially significant differences in the subjective sensations according to fabric characteristics regarding shirt fabrics. As regards the difference in fabric hand according to gender, female students responded with more receptiveness and sensitivity than male students in the category of woven fabric evaluation. In particular, female students responded with more sensitivity to the sensation of dense and wrinkle sensations. There were significant differences in the purchase preference according to gender regarding casual shirt fabrics. Plain weave fabrics made of cotton was most preferred among male students, whereas rib weave fabrics made of cotton/polyester was most preferred among female students.

Students' mathematics application ability is a hot spot which mathematics education pays attention. So, I have carried on the test of mathematics application and the questionnaire survey to student of Senior One of the two middle schools. Through the test and the investigation, I discover that the level of the students' mathematics application ability is not high. To the simple application question, the difference of the male and the female is not big, but to the difficult application question, the male and the female has the remarkable difference. The students' lack of flexible and the original cognition monitoring ability in mathematics application process are afraid of studying mathematics application since childhood and lack of the training of this aspect. They thought mathematics foundation and reading understood ability is the key of mathematics application. Through analysis result of investigation, this paper proposed the way to raise mathematics application ability of students.
