One way of engineering education fiber optic splicing loss was introduced. To make high sensitivity fiber optic sensor it is required low loss of splicing. Hence in this paper splicing loss was selected in the experiments and the splicing loss was evaluated based on the engineering education. After trials in the experiments fiber optic splicing loss depended upon the experimental attitude and its environments.

Purpose: The research were conducted to identify the knowledge, attitude and the preventive behaviour of noise according to noise-induced hearing loss prevention education and to provide primary data for effective noise-induced hearing loss prevention education for noise-exposed workers. Method: 104 noise-exposed workers were included in this study. The instrument used in this study was knowledge, attitude and preventive behavior of noise tool by Lee & Lee(1996). The first data were collected before the noise education from August to September, 2002. During 6 months, the education was provided, and then the second data were collected from April to May, 2003. Data were analyzed by SPSS 10.0 win program for finding frequency, percentage, mean, standard deviation, t-test, and ANOVA. Results: The results of this study were as follows: There were statistically significant differences of knowledge and attitude of noise related education level, and adhesion quality of wearing ear protection equipment after noise education. Also, otitis media's history, received education of the personal protective devices for the hearing conservation was significant in the preventive behaviour of noise. Conclusion: In conclusion, the noise-induced hearing loss prevention education was effective in changing the knowledge, attitude and the prevention behaviour of noise. Therefore, the noise-induced hearing loss prevention education is strongly recommended for noise-exposed workers and it will be necessary repeated education for changing prevention behaviour of noise.

This study has examined weight loss rates of Iyoceu, lyocell/cotton, cotton that were treated with cellulase under different concentration, time, temperature and pH. and compared physical properties changes of tensile strength, drape, moisture absorbency, shrinkage and dyeability. The notable results are summarized as follows: Lyocell was in need of pretreatment by NaOH in the side of weight loss, tensile strength and dyeability. Weight loss rates of cellulose fabrics by cellulase treatment were in the order of cotton > lyocell/cotton > lyocell at the same conditions. In case of lyocell and lyocell/cotton, weight loss rates showed up lower than cotton, while strength retention decreased, drape and strength flexibility were highly improved after cellulase treatment.

The purpose of this study was to investigate the fad dieting status and needs of nutrition education on healthy dieting in male and female collegians according to the desired loss weight. The subjects were 611 students (287 males, 324 females) from universities in Gyeonggi and Gangwon provinces in Korea. The subjects were divided into the following four groups based on the difference between their current body weight and their desired body weight: no desired weight loss (WL0), desired weight loss less than 5 kg (WL5), desired weight loss 6 to 10 kg (WL10), and desired weight loss more than 11 kg (WL11). The fad dieting status was surveyed using a questionnaire about 11 selected trendy dieting methods. The higher desired weight loss group showed higher current weight and BMI in both males and females. Self weight overestimation was higher in the females than in the males, and in the WL10 group than in the other groups of males. As desired loss weight increased, weight loss trials and experienced trendy dieting types increased in both males and females. In the male subjects, the experience of the half meal diet and the chicken breast diet was significantly associated with the desired loss weight. In females, trials of more trendy diet types including the half meal diet, cereal diet, fasting, and Atkins diet were significantly associated with the higher desired loss weight. The need for nutrition education on healthy dieting was high among all the different desired weight loss groups, showing that a minimum of 60% of subjects in each group answered 'necessary and strongly necessary', with the highest in the WL11 group in both males and females. From these results, desired loss weight is associated with higher current weight status, unhealthy weight control practices, and needs for nutrition education in both male and female subjects. Therefore, in the future, nutrition education programs should give greater attention to providing healthy dieting methods for young collegians who desire more weight loss.

The defect detection based on deep learning requires minimal loss and high accuracy to pinpoint product defects. In this paper, we confirm the loss rate of deep learning training based on disc-shaped artificial scaffold images. It is intended to compare the performance of Cross-Entropy functions used in object detection algorithms. The model was constructed using normal, defective artificial scaffold images and category cross entropy and sparse category cross entropy. The data was repeatedly learned five times using each loss function. The average loss rate, average accuracy, final loss rate, and final accuracy according to the loss function were confirmed.

We obtain an asymptotic behavior of the loss probability for the GI/PH/1/K queue as K tends to infinity when the traffic intensity p is strictly less than one. It is shown that the loss probability tends to 0 at a geometric rate and that the decay rate is related to the matrix generating function describing the service completions during an interarrival time.

Aming to find out any relationship between the health status of high school girls and the early loss of their parent, the Cornell Medical Index (C.M.I) Questionnaire and interview method were used for 314 girls as an experimental group and for 300girls as a control group. The study results showed as follows: 1. A significant difference in the health status between the experimental group and the control group was found in that the C.M.I. score showed higher in the experimental group than in the control group. 2. A significant difference in the health status was found in accordance with the sex of the lost parent, the cause of loss of the substitute for the lost parent, the age of losing parent and the duration of loss of parent in the experimental group. 3. A significant difference in the health status in the experimental group showed according to the three variables in the six variables-the sex of the lost parent, the cause of loss of parent, the substitute for the lost parent, the age of losing parent, the duration of loss of parent and the degree of economic support. The most significant factor toward the health status was shown by the age of losing parent, the sex of lost parent and the cause of loss of parent with the order.

The purpose of this study was to examine resting metabolic rate (RMR) and thyroid hormonal (TSH, $T_3$, and $T_4$) changes following weight loss by diet with regular exercise in obese women. The subjects of the present study were 7 women who were above 30% body fat. The subjects arrived into the laboratory in the morning after 12 hour overnight fasting. All subjects measured RMR, % body fat, and fat free mass at weight loss program start time, after 4 weeks and after 8 weeks. All the RMR values were expressed as absolute value (kcal/day), absolute value/FFM (kcal/day/FFM), and absolute value/BSA (kcal/$m^2$/hr), and were calculated predicted RMR value minus actual RMR value. Also, correlation of blood thyroid hormonal (TSH, $T_3$, and $T_4$) secretion and RMR were analyzed. There were significant differences in weight, % body fat, and BSA following diet with exercise (p<0.05). Also, there was a difference between predicted RMR and actual RMR value following weight loss (p<0.05). We also examined the hormonal changes according to weight loss. After weight loss, the level of TSH and $T_4$ were higher than before. But there were no significant differences. Also, the level of $T_3$ was lower than rather before but there was no significant difference. Among the anthropometric factors, FFM was highly correlated (r=0.761) with actual RMR value before weight loss. Also, there was a correlation (r=0.771) with actual RMR value after weight loss. Therefore, actual RMR expressed as FFM increased in weight loss program by diet with exercise. There were no changes in the level of thyroid hormonal TSH and $T_4$.
