The purpose of this study was to analysis biomechanics of the lower extremities injury the heights(40cm, 60cm, 80cm) of jump box as performed depth jump motion by 6 females aerobic athletes and 6 non-experience females students. The event of depth jump were set to be drop, landing and jump. The depth jump motions on the force plate were filmed using a digital video cameras, and data were collected through the cinematography and force plate. On the basis of the results analyzed, the conclusions were drawn as follows: 1. The landing time of skill group was shorter than unskill group at 40cm, 60cm drop height during drop-landing-jump phase especially. The landing time of 60cm drop height was significant between two group(p<.05). 2. The peak GRF of sagittal and frontal direction following drop height improve was variety pattern and the peak vertical force of 40cm drop height was significantly(p<.05). 3. The magnitude of peak passive force was not increase to change the drop height. 4. The peak passive forces was significant at 40cm drop height between two groups(p<.05)

Availability of defect test algorithm that recognizes exact and standardized defect information in order to fundamentally resolve generated defects in industrial sites by giving artificial intelligence to SAT(Scanning Acoustic Tomograph), which previously depended on operator’s decision, to find various defect information in a semiconductor package, to decide defect pattern, to reduce personal errors and then to standardize the test process was verified. In order to apply the algorithm to the lately emerging Neural Network theory, various weights were used to derive results for performance advancement plans of the defect test algorithm that promises excellent field applicability.

The purpose of this study was to investigate the effect of various cooking methods(roasted, salad, deep-fried, seasoned-roasted and commercial laver) on mineral contents, color and sensory evaluation of laver. The contents of mineral of dried laver by various cooking methods were analyzed using the Inductively Coupled Plasma(ICP) system. The results were summarized as follows : The content of crude protein, moisture, ash and crude fat in dried laver were 35.1%, 10.6%, 9.7% and 0.8%, respectively. Among the minerals of dried laver, the content of poassium was the highest (2268.0㎎/100g d.w.) and those of calcium and iron were comparatively high (495.1㎎/100g, 13.5㎎/100g). Ca/P ratio of dried laver was about 1:1 levels. Among various laver dishes, the total mineral content was the highest in the roasted laver, but low in the deep-fried laver. Among color values by cooking methods, "L(lightness)" and "-a(greenness)" values were the highest in the roasted laver, and "b(yellowness)" was the highest in the deep-fried laver. The seasoned-roasted laver was highly scored by the sensory evaluation.

Public perception concerning water fluoridation and influencing factors were assessed. A mailing survey was conducted in 1999 with a representative sample of the general Seoul citizen (response rate=40.1%), who consisted of 1108 adults aged between 20 and 78. The data were analyzed using the chi-square test and structural equation modeling. 48.3% favored and 11.4% opposed water fluoridation while 40.5% were not certain. The contact on information about water fluoridation was the most significantly influencing factor on the perception concerning water fluoridation while experience of marriage, income and the perception of tap water were also significant. 52.8% expect governmental health authorities to take the decisions about water fluoridation.

Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

In today's international society, growth and prosperity of a company can be achieved by enhancing international competitiveness. Evaluation technique for international competitiveness between companies is an important part of the methodology for enhancing international competitiveness within a company. Since it is not reasonable to evaluate the entire entity of competitiveness by considering only few aspects of the company, techniques must be developed for competitiveness evaluation by simultaneously considering many aspects of the company. In this article, two such techniques are presented. One select representative competitiveness indices, and the other evaluates competitiveness by utilizing the ranking method.

This study was conducted to provide the data-base for nursing implementation of reducing depression through the investigation of the relations among depressed mood, social support, and gender role barrier in middle aged women. The subjects included 241 middle-aged women who reside in Seoul or the suburbs of Seoul. SDSby zung, SSBC, and the gender role barrier questionnaire by Hong were used as the measuring instruments. The period of the study was from October 1 to November 10, 2000. Collected data was analyzed using frequency, percentile, t-test, ANOVA, Scheffe´ test, Pearson Correlation Coefficient, Stepwise Multiple Regression by SAS program. The result were as follows. 1. The degree of depression of the subjects was relatively low(1.89±0.41), showing a education, and economic status. 2. The level of social support of the subjects was relatively high(2.95±9.55), showing a significant difference according to education. 3. The degree of gender role barrier of the subjects was relatively high (2.47±0.54). There was a significant difference according to education, living with parents-in-law. 4. The degree of depression had a negative correlation with social support, and had a positive correlation with gender role barrier. 5. The predictive variables of depression are gender role barrier, social support, occupation, age, menopause variable. The combination of all predictive variables explained 41.8% of the variance of likelihood to engage in depression of middle-aged women. In conclusion, the results show that social support and gender role barrier relate to depression in middle-aged women. It suggested that the goal of care for depression in middle-aged women should be to help hem reduce barrier to gender role with a greater degree of social support.
