Over the period between January 1997 and December 1998, herbal medicine was more than three times administered to the patients coming to Na dong gyu's Oriental Medical Clinic on account of the symptom of growth deficiency. According to radiological opinions about the patients providing cooperation for measuring their height and weight as well as their bone age every three months, it was found that the growth plates were not closed. A research was conducted for 200 children randomly selected of patients in prepuberty (they grew by less than 5cm a year before treatment at a age of 12years for female children and 14years for male children). As a result, the following conclusion was drawn: 1. The randomly selected subjects were made up of 116 male and 84 female children in terms of gender. The age direstribution was most 10 to 12 years in 86 children(34.00%), followed by 8-10 years(27.50%) and 12 to 14 years(19.50%). 2. Considering the distribution of sick children's parental height, the fathers of 141 children(70.50%) measured less than 170cm high, the subaverage height, while the mothers of 172 children(86%) measured less than 160cm high, the subaverage height. It was shown that sick childen's height was genetically influenced by their parents. 3. Children patients's weight at a time of birth was most 3.1-3.5kg for 85 children(44%) and less than 2.5kg which came under the range of growth dificiency for 19 children(9.5%). 4. The highest proportian of the children patients with growth dificiency(56.33%) had the symptom of digestive disorders, of which 77 children patients(18.78%) had anorexia, 16.59% of children patients had the high level of respiratory disorders. Both the digestive disorder and the respiratory disorder put together, they had the high rate of 72.92%. Therefore, this indicates that both the digestive disorder and the respiratory disorder have a great effect on children's growth dificiency. 10.74% of chilren patients were shown to have allergic disorders, which indicates that they also exert an effect on growth deficiency. Specifically, 7.07% of the children patients had the high level of obesity, which shows that an excessive uptake of nutrition may rather induce children to have growth dificiency though an appropriate amount of nutritional uptake is necessary. 5. Comparing their bone age and their chronological age, 58 children patients(29.00%) showed that they were the same at the highest percent. 79 children patients(39.50%) showed that thier bone age was lower than their chronological age. And 63 children patients(31.50%) showed that their bone age was higher than their chronological age. 6. As regards the prescription administered to children patients for treating their growth dificiency, Growth tang A related to the kidney, the congenital factor, of the causes for growth dificiency in traditional Oriental Medicine was administered to 108 children patients(54%), whereas the Growth tang B related to the spleen, the acquired factor, was administered to 92 children patients(46%). 7. 116 male children patients with growth dificiency had the average value of growth for one year before treatment, 4.39cm, while 84 female children patients had the average value of growth for one year before treatment, 4.24cm. A total of 200 children had the average value of growth for one year before treatment, 4.33cm. The annual average value of growth in growth curve surveyed by the Korea Pediatrics Society was 5.79cm. Compared to this value, the one year average value of growth for 108 male and female children patients taking Growth tang A was shown be 8.44cm, which indicates a greater growth by 4.12cm(95.37%) in comparison with the average value of growth before treatment, 4.32cm, and a greater growth by 2.65cm(45.77%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Also, the average value of growth before treatment for 92 male and female children patients taking Growth tang B was shown to be 8.47cm, which indicates a greater increase by 4.15cm(96.06%) compared to 4.32cm, the average value of growth before treatment and a greater increase by 2.67cm(46.29%) in comparison with 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Considering the average value of growth for male and female children patients taking Growth tang A and B, it was shown to be 8.46cm, which indicates a greater increase by 4.14cm(95.81%) compared to 4.32cm, the average value of growth before treatment, and a greater increase by 2.67cm(46.11%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society.

Purpose: This study aimed to explore the association between demographic characteristics, hospitalization-related characteristics, and the severity of long-term hospitalization in a high-level general hospital, and to analyze the factors influencing decisions of all patients. Methods: General and clinical characteristics of the participants were analyzed using frequency, percentage, mean, and standard deviation. Differences in these characteristics, contingent upon whether a power source was requested, were analyzed using independent t-Test and Chi-squared tests. Logistic regression analysis was used to identify the factors related to the presence or absence of power requests. Results: The factors impacting the decision to refer a dependent variable include medical treatment (neurosurgery) (B=2.118, SE=0.960, p-value=.027, OR=8.314, 95% CI=1.267-54.551), infection isolation (CRE) (B=1.336, SE=0.666, p-value=.045, OR=3.804, 95% CI=1.032-14.021), and the utilization of tertiary antibiotics (B=3.076, SE=1.362, p-value= .024, OR=21.663, 95% CI=1.502-312.530). Conclusion: This study found a significant association between medical treatment (neurosurgery), infection isolation (CRE), and the use of tertiary antibiotics as dependent variables. These findings indicate that continuous monitoring can contribute to a reduction in long-term financial burdens.

Silk has always been coveted as the finest and richest of all fibers woven into cloth. The earlist woven silk fragments found to date come from the third century B.C. The filament created and spun into cocoon by the larva of the silk moth, silk was exported from China to Europe from as early as the third century B.C. Silk industry is export leading industry that guide national textile industry development after the 1960s in Korea. Korean silk industry reached to peak at 1975 is displaying appearance that export scale is decreased recently. Various kinds methods can be proposed for high value added in silk industry, the research about color is essential. The importance of color is increasing in modern textile and fashion industry. Color is important factor of textile and fashion industry because color affects strong influence in human's sensitivity. Silk fabric can give high added value developing high sensitivity color because dye ability is superior.

Various sintered magnets containing $28{\sim}31\;wt%$ Nd and $0{\sim}7\;wt%$ Dy were evaluated for coercivity and irreversible flux loss as a preliminary study to develop highly-coercive, high-temperature magnets that can be applied for driving motors in a hybrid vehicle. The sintered magnets were prepared in sequence of strip casting, HD treatment, jet milling, magnetic field pressing, sintering and post-annealing. Increasing Dy content and adjusting post-annealing temperature monotonically increased coercivity of magnets from about 14 kOe to 30 kOe. A magnet containing 28 wt% Nd and 7 wt% Dy exhibits a $(BH)_{max}$+$_i{H_c}$ value of almost 64. This is very close to what the automobile industry considers as the minimum value (65) for a hybrid vehicle system. Moreover, irreversible flux loss of the magnet was about 3% at $200^{\circ}C$, which is well less than the allowable limit (5%) to a driving motor in hybrid vehicles.

The nearest neighbor query is an important operation widely used in multimedia databases for finding the object that is most similar to a given query object. Most of techniques for processing nearest neighbor queries employ multidimensional indexes for effective indexing of objects. However, the performance of previous multidimensional indexes, which use N-dimensional rectangles or spheres for representing the capsule of the object cluster, deteriorates seriously as the number of dimensions gets higher. This paper proposes a new index structure based singular value decomposition resolving this problem and the query processing method using it. We also verify the superiority of our approach through performance evaluation by performing extensive experiments.
