The purpose of this study is to suggest how we can get over the difficulties of practical drill under experimentation concerning the units of making clothes in the curriculum of home economics. The import of this study was based on the results of the preceding studies the field of the making Korean clothes, from the standpoint of the teaching tools and teaching materials by the use of VTR, is one of the most insufficient. On the one hand, the teaching procedure here a VTR, running 34 minutes or so, was made up with the process of making Korean men’s slacks, and was led by the researcher’s own. The contents of the lesson are as follows： the shape of Korean clothes, the name of each part, the process of drawing, cutting and sewing, and the items of evaluation and arrangement. On the other hand, the two comparative groups were made to compare one with the other： One group was taught by help of VTR media, and the other by the model performance and explanation of the instructor’s own. All of the statistical data were analyzed in terms of SPSS/PC, and t-verification was made, to make difference between the two, after standard deviation was calculated according to the classified domains. The consequences of the test research are shown as below： 1. The difference of understanding was obviously made in considering that the group made a better score than the comparative one in understanding to process of making Korean clothes. 2. The difference of skill was highly made in considering that the group made a better score than the comparative one in the practical drill of making Korean clothes. 3. The difference of interests was evidentally made in considering that the group made a better score than the comparative one in the stage of making Koran clothes. Such means that the motivation and attitude of the learners was made stimulate by the Audio-Visual material than by the traditional cramming method. 4. The difference of frequency was fairly made in considering that the experimeatal group made a better score than the comparative one in the frequency of individual teaching. 5. The difference of the efficiency of time-consumption was clearly made in considering that the experimental group made a better score than the comparative one. As the results of the research above, the medium of VTR proved to more effective to the achievement of schoolwork and the strategies of teaching. Therefore, more use of VTR media will help the instructors with the difficulties of practical drill in the whole process of making Korean clothes； Widely use of VTR media in teaching will be surely more fruitfull to the unit of making Korean clothes than teaching by explanation.

The purpose of this study was to help the women with stress urinary incontinence lead more comfortable life, by letting them to do pelvic muscle exercise and to learn by direct experience the effect that urinary incontinence is controlled. The research design was a one-group pretest-posttest design. The subjects were 16 middle-aged women(over 38) with stress urinary incontinence. The study was conducted from August 1, to October 11, 1999. Women trained themselves for muscular strength and endurance, every the other day for each exercise for six weeks at home(that means each exercise for more than three days a week) in the pelvic muscle exercise program which was developed by Dougherty et al., and filled out exercise participation card every week. They visited laboratory once a week to get visual feedback, by means of Perineometer, of how the pelvic muscle exercise was going on. Stress Urinary Incontinence Scale that Lee, Young-Sook revised and supplemented Hendrickson's original scale was used for measuring the frequency and situation scores of urinary incontinence, "30 minute pad test" was carried out for measuring the amount of urinary incontinence, and Perineometer was used for measuring maximum vaginal contraction pressure. Percentage, mean, standard deviation and Wilcoxon signed ranks test were used for data analysis by means of SPSS/PC+ WIN 9.0 program. The results were summarized as follows : The hypothesis 1 that after carrying out pelvic muscle exercise program on women with stress urinary incontinence, the weekly degree of urinary incontinence would reduce compared to before the exercise was supported. The hypothesis 1-1 that after carrying out pelvic muscle exercise program on women with stress urinary incontinence, the weekly frequency of urinary incontinence would reduce compared to before the exercise was supported (p=.003). The hypothesis 1-2 that after carrying out pelvic muscle exercise program on women with stress urinary incontinence, the situation scores of urinary incontinence would reduce compared to before the exercise was supported(p=.044). The hypothesis 2 that after carrying out pelvic muscle exercise program on women with stress urinary incontinence, the amount of urinary incontinence would reduce compared to before the exercise was supported(p=.001). The hypothesis 3 that after carrying out pelvic muscle exercise program on women with stress urinary incontinence, the maximum vaginal contraction pressure would increase compared to before the exercise was supported (p=.012). These results suggest that pelvic muscle exercise program has an effect on women with stress urinary incontinence in the degree and amount of urinary incontinence and maximum vaginal contraction pressure. So it is judged that training women with stress urinary incontinence for pelvic muscle exercise is an effective nursing intervention strategy in order to care urinary incontinence.

The geoid is the level surface that closely approximates mean sea level and usually used for the origin of vertical datum. For the computation of geoid, various sources of gravity measurements are used in South Korea and, as a consequence, the geoid models may show different results. however, a limited analysis has been performed due to a lack of controlled data, namely the GPS/Leveling data. Therefore, in this study, the gravimetric geoids are compared with the geodetic geoid which is obtained through the GPS/Leveling procedures. The gravimetric geoids are categorized into geoid from airborne gravimetry, geoid from the terrestrial gravimetry, NGII geoid(geoids published by National Geographic Information Institute) and NORI geoid(geoi published by National Oceanographic Research Institute), respectively. For the analysis, the geometric geoid is obtained at each unified national control point and the difference between geodetic and gravimetric geoid is computed. Also, the geoid height data is gridded on a regular $10{\times}10-km$ grid so that the FFT method can be applied to analyze the geoid height differences in frequency domain. The results show that no significant differences in standard deviation are observed when the geoids from the airborne and terrestrial gravimetry are compared with the geomertric geoid while relatively large difference are shown when NGII geoid and NORI geoid are compared with geometric geoid. Also, NGII geoid and NORI geoid are analyzed in frequency domain and the deviations occurs in long-wavelength domain.

Stress involves changes in behavior, autonomic function and the secretion of hormones. Autonomic nervous system (ANS) contributes to physiological adaptive process in short durations. In particular, heart rate variability (HRV) analysis is commonly used as a quantitative marker depicting the ANS activity related to mental stress. The aim of this study is to investigate correlations between psychological responses to stress and HRV indices induced by the cognitive stressor. Thirty-three participants rated their mental and physical symptoms occurred during the past two weeks on Stress Response Inventory (SRI), which is composed of seven stress factors that may influence the status of mental stress levels. Then, they underwent the psychophysiological procedures, which are collected electrocardiogram (ECG) signals during a cognitive stress task. HRV indices, the standard deviation of R-R interval (SDNN), root mean square of successive R-R interval difference (RMSSD) and low frequency (LF)/high frequency (HF) ratio were extracted from ECG signals. Physiological responses were calculated stress responses by subtracting mean of the baseline from the mean of recovery. Stress factors such as tension, aggression, depression, fatigue, and frustration were positively correlated to HRV indices. In particular, aggression had significant positive correlations to SDNN, RMSSD and LF/HF ratio. Increased aggressive responses to stress correlated with the increases of all HRV indices. This means the increased autonomic coactivation. Additionally, tension, depression, fatigue, and frustration were positively associated with RMSSD reflecting increases in parasympathetic activation. The autonomic coactivation may represent an integrated response to specific cognitive reactions such as the orienting response.

In this study, vibrational tendon tension measurement methods are applied to estimate tension of external tendons used in segmental post-tensioned bridges. The acceleration of various length type of tendons is measured and natural frequencies are obtained using FFT (Fast Fourier Transform). The obtained natural frequencies are within 1% error regardless of sensor direction and location. On the basis of natural frequency of tendon, estimation of the tendon tension is performed by using many types of solutions such as string theory equation, multi mode estimation, practical formula estimation and stiff string with clamped-clamped boundary conditions. The results are compared with each other and have shown that the flexural stiffness is not negligible in tendons of this type causing the vibration mode to be inharmonically related. The results have shown that the method using stiff string equation with clamped-clamped boundary conditions is more accurate than the other methods. Application example of in-service bridges has shown that force distribution effects from friction at deviation blocks can be effectively detected.

Objectives: This study was designed to provide basic information for smoking prevention education for middle school students by examining their knowledge and attitudes toward smoking. Method: A survey was conducted in this study on 1.250 students from 12 middle schools in the six educational bureaus in the Busan region. Results from the preliminary survey showed that the reliability of the instruments for knowledge and attitudes toward smoking were 0.84 and 0.86. respectively. The data for this study were collected for 20 days from Dec. 1 to 20, 2000, and then statistically analyzed with the SAS program using frequency, percentage, mean and standard deviation. and two-way ANOVA. Results: (1) The highest frequency of responses found that both male and female students did not smoke at all. Among 170 students who had experiences of smoking, 66.5% reported they tried smoking because of curiosity, and 38.2% reported they first smoked during the 2nd grade of middle school and 1.2% during 4th grade of primary school. (2) In scores on smoking knowledge, the item with the highest score in both male and female students was one that they had no smoking experiences et al. followed by smoking experiences in the past and experiences of regular smoking. (3) In scores on attitude toward smoking, both male and female students were scored as the highest at the item that they had no smoking experiences et all. followed by the item that they smoked in the past and that they experienced regular smoking. (4) There was no significant correlation between knowledge and attitude toward smoking among the whole subjects (r=0.09. P=0.00). With regard to regular smoking experiences among the male and female students at the 3rd grade of middle school. there was a relatively high correlation between knowledge and attitude toward smoking among them (r=0.57. P=0.00: r=0.56. P=0.01). Conclusion: Students who had never smoked or smoked only in the past need smoking prevention education consistently. Particularly, for those who were regular smokers, not only individualized but also organized in small size groups, they need an intensive educational program on the basis of counseling to reduce smoking and to put in practice smoking cessation.

Objectives: To investigate the drinking and smoking habits among the community residents of a city. Methods: We surveyed 1.973 adults from October 1, 2005 to November 16, 2005. The data collected on alcohol drinking habits involved frequency, age of initiation, amount of alcohol consumed, number of attempts to reduce consumption and reasons for reducing it. The data collected on smoking habits involved amount, age of initiation, duration, situations, and the number of attempts to quit smoking. These were analyzed with frequency, percentage, mean, standard deviation, $x^2$-test, t-test and ANOVA. Results: The rate of drinking was 67.4%; 83.1% among males, and 52.5%among females. Among all drinkers, the largest group (29.8%) drank once or twice a week. The mean age of initiation was 21.2 years; 19.9 among males, and 22.8 among females. The average consumed amount was 5.8 glasses; males consumed 7.4 glasses, and females 3.3 glasses. The consumption was the highest among those in fifties. The rate of attempts to reduce drinking was 33.4%, mainly for health reasons. The rate of smoking was 38.0%; 72.4% among males, and 5.5% among females. Among all smokers, the largest group (44.1%) smoked between 11 and 20 cigarettes per day. The mean of the age of initiation was 20.7 years; 20.3 among males, 25.6 among females. The mean smoking duration was 20.9 years; 21.3 years among males, and 16.2 years among females. The main reason for the initial attempt was curiosity. The most common situation for smoking was after dinner. The rate of attempts to quit smoking was 77.1%, mainly out of concern for one's health. Alcohol consumption among smokers was higher than among any other group of nonsmokers. Also, the age of drinking initiation among smokers was lower than among any other group of nonsmokers. Conclusion: This study highlighted the actual data on drinking and smoking habits among community residents. The study can be utilized for creating programs aiming at reducing the consumption of alcohol and tobacco or stopping it altogether. Therefore, it is now possible to assess the indicators for interventions in each population group. Finally, the groups of heavy drinkers and smokers are expected to be given priority for intervention program.

In this paper, we propose a new method to predict a mirror's surface deformation due to the stress of moisture release by a coating in the environment of outer space. We measured the surface deformation of circular samples 50 mm in diameter and 1.03 mm thick, using an interferometer. The results were analyzed using Zernike fringe polynomials. The coating stress caused by moisture release was calculated to be 152.7 MPa. This value was applied to an analytic model of a 1.25 mm thickness sample mirror, confirming that the change of surface deformation could be predicted within the standard deviation of the measurement result ($78.9{\pm}5.9nm$). Using this methodology, we predicted the surface deformation of 600 mm hyperbolic mirror for the Compact Advanced Satellite, which will be launched in 2019. The result is only $2.005{\mu}m$ of focal shift, leading to 2.3% degradation of modulation transfer function (MTF) at the Nyquist frequency, which satisfies the requirement.
