To obtain information about knowledge and attitude toward sex, sexural experience and need of sex education, a questionnaire survey was conducted on 599 students who were attended in 2nd grade of 2 girls' high schools(A group: 190 girls), 2 vocational girls' high schools(B group: 205 girls), and 2 special girls' high school attached to industrial company(C group: 204 girls) in Taegu city between 20th and 25th April 1992. Mean score of knowledge toward sex of the total was 9.3. Mean score of A group was higher than that of Band C groups. Among the total students, vocational high school girls were the highest affirmative attitude towards the acquaintance and relationship with the other sex, and the next was special high school girls. Students of B group assumed the highest negative attitude towards artificial abortion, and the lowest was A group. Among the respondent girls, 31.1% did not experienced in the acquaintance and relationship with the other sex and 86 girls(14.4%) had experience with sexual affairs. Most of girls(96.9% of A group, 90.4% of B group and 86.8% of C group) agreed to necessity of sex education, and answered that current education on sex was insufficient to them(80.6% of A group, 82.6% of B group and 62.4% of C group). Among what the surveyed girls wanted to know about knowledge towards sex, they showed the highest interest on the acquaintance and relationship with the other sex(A group: 44.7%, B group: 45.4%, C group: 56.4%). And they showed the second highest interest on pregnancy and delivery(A group: 33.2%, B group: 32.6% , C group: 26.5%). There was no unique difference among each surveying item. Most of the students(A group: 46.8%, B group: 40.1%, C group: 36.3%) thought it better that the time they wanted to get education on sex in 5th or 6th grade of elementary schools and to have a regular curriculum on sex education.

Objectives: The objective of this study was to investigate the prevalence rate and factors related with low back pain(LBP) in senior high school teachers. Methods: Questionnaires were completed by 405 teachers at 13 high school in Andong city in July 2-14, 2001. The information was used to estimate odds ratio(OR) and 95% confidence intervals(CI) for factors relation to LBP prevalence. A cross-section study design was used in this study. Results: The pointprevalence rate for LBP was 26.4%, prevalence rate for 6 months was 36.0%, prevalence rate for 1 year was 36.5%, and experience rate during life time was 55.1%, The factors associated with LBP by Chi-square test were marital status(p=0.014), An angle for back rest of car seat(p=0.014), and vibration of seat (p=0.003), 12.2% for patients with LBP was a higher than 6.0% for without in singles, Patients(29.0%) were higher than no patients(17.8%) in above $100^{\circ}$. 14% for patients who exposed to a high vibration. Vibration significantly associated with point prevalence rate for LBP were marital status and lecture time in logistic analysis. The married teachers had a higher LBP experience than singles(OR=2.6, 95% CI 1.13-6.03). The teachers who have a lot of lecture time in a day had a higher experience than those for less time(OR=1.6, 95% CI 1.42-2.51). Conclusions: Results from this study indicate that a statistical significant factors relation to LBP were marital status and lecture time in a day.

In order to grasp the occupational add social characteristics of the onset of lumbago among elementary and high school teachers, 423 elementary and high school teachers were taken as subjects of study through questionaires. The following are the results of the study which were analyzed through data, conducted for one month in the City of Taegu, between Jun. 90, and Jul. 20 of 1993: 1. the incidence of lumbago of the entire teachers was $75.2\%$, with the elementary school teacher$(81.9\%)$ higher than high school teacher$(70.6\%)$. 2. In the relationship between the characteristics of job and lumbago. characteristics of teaching, monthly income, chores and satisfaction with job did not show significance, but weekly teaching hours, mental stress and the degree of comfort of chair reflected significantly(p<0.01). 3. In social relationship, personal nature, sleeping hours and place, smoking and drinking did not hold significance, but daily average walking hours, posture during sleep, general health conidition(p<0.01) and daily average riding hours and regular exercise(p<0.05) etc. showed significant relationships. 4. In the sistuation of lumbago of the teacher groups, no significant differences wee found in the cause of lumbago, duration of lumbago, sick leaves and recognigion of lumbago, but it was contrary in the treatment of lumbago(p<0.01). Based on the above results, lumbago is closely related to occupational and social factors, the prevention and treatment can be diversified based on occupation and environment. Consequently, regular educational program is considered imperative mainly on prevention of lumbago by putting aside time for such purpose.

Objectives: This study was taken to investigate factors related to dental caries in deciduous teeth of preschool children. Methods : this study was completed by oral examination on 623 kindergarten pupils and questionnaire on their mothers in Sangju city from April 1 to May 20, 2001. Study design is Cross-sectional Study. Results: The mean values for decayed teeth indexed(dt index), filled teeth index(ft index), and decayed and filled teeth index(dft index) was 2.46, 1.85, and 4.30 respectively. 2.05 for girl was significantly lower than 2.77 of boy in gender (p<0.01). As child ren got older, values were higher(0.7 and 2.84 of three years old, 1.6 and 4.01 of four, 2.42 and 5.02 of five) in ft and dft index(p<0.001). Also, Mother age was almost same, that is, 4.12 dft value for 30~34 years was smaller than 6.17 for above forties(p<0.001). 2.07 and 4.68 for mothers who graduated from high school were higher than 1.36 and 3.34 for university in the ft and dft index(p<0.05), that is, the more they had a high educational level, the lower they got a values. Value 2.76 for children who had non cariogenic food was lower than 5.11 for those who had cariogenic food in dft index(p<0.001). In dft index, 3.82 of children who have learned the education on oral health from mother frequently have lower than 45 of children who have never learned (p<0.05). The ft value of children who had a snack food with mother(1.29) was a smaller than children had it at out of home(1.97)(p<0.05). The variables related 10 dft index were children and mothers age, educational level, and kinds of snack food (p<0.05). Conclusion : This study reveals that younger girl, younger mother, higher educational level, and non cariogenic foods showed lower dft index.

The purpose of this study is to identify the bridge exercise posture for the efficient exercise by comparing the muscle activity of the lower limbs according to the changes in muscle length because of knee angle in bridge exercise. The subjects of this study were 9 randomly selected males in their 20s living in D city from those who satisfied inclusion criteria. The measured muscles were Vastus medialis oblique, Vastus lateralis, Semitendinosus, Biceps femoris, Gluteus maximus, Gluteus medius, Tensor faciae latae, and Adductor longus. Data were analyzed through paired comparison test. In the result, ST, BF, and TFL muscle activities were high when knee joint flexion angle was $90^{\circ}$ Although in most cases higher muscle activity was shown at $90^{\circ}$ than $60^{\circ}$ there was no statistical significance. Interestingly, it was lower at $90^{\circ}$ than $60^{\circ}$ in VL. In ST, BF, and TFL, it was significantly higher at $90^{\circ}$ than $60^{\circ}$ (p<.05). Conclusively, knee angles in bridge exercise may affect the muscle activity, and in particular when the activity of two joint muscles such as semimenbranosus muscle, biceps femoris muscle, and tensor fasciae latae muscle increase as the angle gets higher. Therefore, it is considered that this study will provide helpful tips to develop muscular strength enforcement program for the patients with damages in the lower limbs through bridge exercise in clinical situations.

We have investigated the astronomical observational environments at the Choejung-san GEODSS site which is located at the south of Taegu, Korea. As a part of the investigation, seeing and night sky brightness were measured outside nearby the GEODSS site using the Celestron 8-inch portable reflector with $192{\times}165$ pixels Lynxx CCD camera during the period of December 1994 to April 1996. The average seeing values of 4.8 arcsecond in B filter and 5.1 arcsecond in V filter were determined using the IRAF software. These values might be overestimated and would be reduced by at least 1 arc second in both filters if they were measured by more stable telescope system with solid mount and under a dome. We also compare the average seeing value at the GEODSS site with those at three other observatories, the Bohyunsan Optical Astronomy Observatory, the Sobaeksan Optical Astronomy Observatory, and the Seoul National University Observatory, for justification of the above guess. Unfortunately the night sky brightness measurement was not successful mainly due to the short exposure time. The utilizing plan of the GEOSS site is discussed based on the average seeing value, naked-eye sky brightness measurement, analysis of the existing thirty-year weather data and twenty-year urban planning of the metropolitan Taegu city for the year of 2016.

The purpose of this study is to find out the orientations and characteristic in clothes buying of each age group of elderly women, based on the actual self-image and the ideal self-image of clothing. Grasping the diversity of their clothes' buying orientations will be helpful in making a better merchandise production planning for apparel, and in launching new brands into the market. The study will also provide useful data in developing sales strategies which enable to supply goods that meet consumers' needs and tastes in the quality market, and consequently will help to classify the market. Samples were 488 women of 55 and over, dwelling in Pusan Metropolitan City. The data was analysed by using MANOVA, ANOVA, and the Cronbach's $\alpha$ reliability was also applied. The conclusions based on the theoretical background and the result of questionnaire surveys were as follows: 1. The order of priority of buying orientations based on clothes's actual self-image was 'practicality', 'cautiousness' and 'economical effectiveness' without regard to age. The items that showed the significant differences in 50's were 'cautiousness', 'experimentation', 'fashion-consciousness' and ostentatiouness, and in 70's were 'economical effectiveness', 'experimentation', 'impulsiveness' and 'environmental friendliness', and none in 60's. 2. The order of priority based on clothes' ideal self-image was the same as that of actual one, and there was no significant difference between age groups.

Local government takes an active role in the (re)making of local socio-economic space. To support such an argument, the three different actions by the local government of Taegu, urban planning and local industrial districts, the establishment of special educational institutions, and textile festival are analyzed. The division of the city's space into residential, commercial, and industrial area by local government constrained the location of local manufacturing industries. It also forced textile industry to move to the outskirts of Taegu. As the education level in South Korea rose after the late 1970s, the local government of Taegu as well as local industrial capitalists had to do something to acquire a stable supply of labor to local manufacturing industries, particularly textile one. After the late 1970s, the special classes for the education of local workers, especially textile ones were established within vocational high school and company-operated high schools were also built in Taegu. Finally, local government started a program of textile festival in 1985. Through textile festival, local government as well as local textile business people tried to reproduce textile industry as the main economic activity of Taegu.
