Purpose: The goal is to identify the effectiveness of the IKDC subjective score in the clinical outcome study after reconstruction of the anterior cruciate ligament. Materials and Methods: Twenty-four patients after ACL reconstructions using twelve hamstring autografts and twelve Achilles allografts were evaluated. Lysholm knee score, IKDC subjective score, Knee Outcome Survey score and Tegner activity score were evaluated for the subjective outcome value. Static instability tests, Biodex dynamometer and one-legged hop for distance tests were done for the objective outcome value. Three functional performance tests (FPTs) including Carioca test, Shuttle run test and Co-contraction test were performed for deciding the final results. Each scale was compared with FPTs results and Pearson's correlation test was used to test the correlation between the parameters. Results: IKDC subjective score, single hop test, and quadriceps power in low velocity of Biodex dynamometer tests had a positive correlation with the total FPTs results. Conclusion: IKDC subjective score can be an effective test to evaluate the functional status as well as the subjective outcome after ACL reconstruction.

A steam generator of nuclear power plant has thousands of thin tubes. These tubes play an important role in maintaining the pressure boundary between the primary and secondary side of nuclear power plant. The steam generator tube is easy to be damaged because of the severe operating conditions such as the high temperature and pressure. Therefore, tremendous efforts are made to assess the structural integrity of the steam generator tubes. The eddy current test is the most popular non-destructive test to assess the integrity of the tubes. However, the eddy current test has the limitation to size the flaw accurately because the eddy current signal behavior depends on the total volume of flaw. This paper shows the possibility that the ultrasonic test method can be applied to detect the flaws in the steam generator tubes and to measure them quantitatively. From the test results, it is expected that if the ultrasonic test is put to practical use in the steam generator tube inspection, the inspection results will be improved.

The Korean Performance Demonstration(KPD) System for the ultrasonic testing personnel, equipments and procedures applicable to the Class 1 and 2 piping examination for nuclear power plant in Korea has been established. A round robin test was conducted in order to compare the examination results by the method of Performance Demonstration(PD) with the traditional dB-drop method. The round robin test shows that the reliability of the PD method is better than that of the dB-drop method. As a result, adoption of the PD method to the in-service inspection of the nuclear power plants will improve the reliability of the ultrasonic test results.

Objectives : The purpose of this study was to evaluate the difference of psychometric analysis among patients with Post-traumatic organic mental disorder according to the lesion of MRI finding of traumatic brain injury. Methods : We divided 35 patients into 4 groups according to the lesion of MRI finding of brain injury. We evaluated the difference of the subscales of MMPI and K-WAIS among 4 groups with Post-traumatic organic mental disorder by ANOVA. Results : We found no significant difference of all subscales of MMPI and K -WAIS among 4 groups by ANOVA. Compared Rt hemispheric injury group with Lt hemispheric injury group by independent t-test, the depression scale in MMPI scored significantly higher in Lt hemispheric injury group, and the block design in K-WAIS scored significantly lower in Rt hemispheric injury group. Conclusion : This study suggests that Lt hemispheric injury be significantly related to depression, and Rt hemispheric injury be significantly related to visuospatial ability.

The cardiovascular disease has been known as a common cause of death for a long time in the west. The eating habits of Asia, including Korea, have changed recently, so that this disease is also a problem in Asia now. Annual Report on the Cause of Death Statistics from 1996 to 2006 reported that the cardiovascular disease would become the number one cause of death in the next $5{\sim}10$ years. Therefore we realize that more accurate examination is required. The aim of this study was to investigate the accuracy of Calcium-scoring CT and the relationship between risk factor and quantitative scores of Calcium-scoring CT. Through this study we expect that the national public health will be improved. Seventy patients with chest pain were chosen at random. The patients were undergone both coronary CT antigraphy and Calcium - scoring CT at G hospital in Incheon from February 1 to June 30, 2008. The result of the Calcium-scoring CT showed its usefulness for Ischemic cardiovascular disease, with an accuracy similar to that of exercise/pharmacologic stress or ECG when it is difficult for a patient to exercise due to joint problems, aging or for other reasons.

This study examined the correlation between the rhythm reproduction performance and cognitive function of school-aged children. A total of 59 third grade elementary students participated in this study. An iPad-based rhythm reproduction task, the Digit Span Test (DST), the Children's Color Trails Test (CCTT), and a self-paced tapping task via a MIDI keyboard were conducted for each participant. The results demonstrated that scores at each stage of the iPad-based rhythm reproduction test showed different patterns of correlation with cognitive function test scores. This result suggests that accuracy of a simple rhythm task is correlated to speed of self-paced tapping (second). Also cognitive function may affect rhythm grouping ability. Results of this analysis for each of 20 rhythm items showed that there was a common rhythm characteristics that correlated with executive function, working memory or self-paced tapping speed. These results indicate that rhythm ability is related to, and predictive of, the level of cognitive functioning in elementary school students and can be used as an useful parameter when examining cognitive function of school-aged children in multifaceted dimensions.

Purpose: Many diagnostic modalities have been used for diagnosis of gastroesophageal reflux disease (GERD). Feeding materials during esophageal pH monitoring may interfere the result of examination and esophageal pH monitoring can not diagnose GER in case of alkaline reflux. The purpose of our study is to evaluate whether scintigraphy can substitiute 24 hr pH monitoring in children with GERD. Methods: From March 2002 to June 2003, 23 patients (12 boys and 11 girls, mean age 27 months) who have been admitted to Hanyang University Hospital presented with GER symptoms (recurrent vomiting, cough, chest pain, irritability) were included in the study. Scintigraphy and 24 hr pH monitoring were performed in all patients. Results: Six out of the 23 patients (26.1%) had evidence of GER on 24 hr pH monitoring, whereas nine of 23 patients (39.2%) exhibited GER by scintigraphy. Two out of the 23 patients could not be tested because of irritability. Three (14.3%) patients had evidence of GER on both 24 hr pH monitoring and scintigraphy, three (14.3%) patients on only 24 hr pH monitoring, six (28.6%) patients on only scintigraphy, and nine (42.9%) patients had no evidence of GER on both methods. No correlation was observed between 24 hr pH monitoring and scintigraphic results by Fisher's exact test (p=0.523) or Kendal's tau (t=0.678). Conclusion: The results of this study demonstrated that there was no correlation between 24 hr pH monitoring and scintigraphy. Therefore these modalities could be used as complementary tests to diagnose GERD.
