The Hahn double 15 hue test is used for social and vacational aptitude test to separate strongly and mildly affected subjects among the colour vision defective persons, detected using colour vision test. However, the assessment of colour vision defect type and severity is based on the hue confusions which are represented diagrammatically on Hahn double 15 hue score sheet, this qualitative assessment of the test results have not provide a numerical score suitable for mathematical analysis. This paper presented a new proposal for quantitatively scoring the Hahn double 15 hue test based on those hue confusions made by the subject. With this program large numbers of double 15 hue test results can be processed easily and rapidly, and program helps to compare the severity of specific type colour vision defect and monitor acquired colour vision defect which has various disease process, continuously.

2.The Effects Of Tooth Mobility And Design Of Direct Retainer On The Stress Of Supporting Tissues In Unilateral Distal Extension Removable Partial Denture.
The Journal of Korean Academy of Prosthodontics 2000;38(1):59-72
This study was performed to investigate the effects of tooth mobility and design of the direct retainer on the stress of supporting tissues in distal extension removable partial denture. Tooth mobility was simulated and four different types of direct retainer such as Akers clasp, I-bar clasp, wrought wire, and Dalbo attachment were designed and stress o the supporting tissues were measured and analyzed with straingauge method. The following conclusions were drawn from this study. 1. The stress revealed at the lingual side of alveolar bone of the abutment tooth in edentulous area was the largest. 2. The stress at the lingual side of alveolar bone of the abutment tooth in edentulous area was increased according to the increases of tooth mobility in I-bar clasp and Dalbo attachment. 3. The stress at the residual ridge crest was the great in Dalbo attachment on mobility 0, in I-bar clasp on mobility 1, and in wrought wire clasp on mobility 2. 4. There was little changes of stress according to the increase of tooth mobility at buccal and lingual side of the residual ridge crest and around the abutment teeth in dentulous area.

Eosinophilic gastroenteritis is a rare disorder of unknown etiology characterized by protein losing enteropathy, peripheral eosinophilia and iron deficiency anemia secondary to gastrointestinal blood loss. It is often accompanied by signs of systemic allergy. This case of a 26-month-old male patient who developed scrotal edema and diarrhea for a month had peripheral eosinophilia ranged from 24 to 32% of total leukocyte, iron deficiency anemia and hypoalbuminemia with slightly increased level of serum lgE. Biopsies of the stomach and duodenum demonstrated marked eosinophilic infiltration of the mucosa and lymphatic dilatation, which was consistent with eosinophilic gastroenteritis. We report a case of eosinophilic gastroenteritis with a brief review who was treated with corticosteroid alone and had marked symptomatic improvement.

Korean Circulation Journal 1995;25(6):1217-1224
BACKGROUND: Ischemic preconditioning reduces the infarct size and the severity of arrhythmia in a post-ischemic reperfused heart although the detailed mechanism is unknown. In the ischemic heart, a large amount of catecholamine is released from the adrenergic nerve terminal and this aggravates cell destruction and arrhythmia. In this study, the possibility for ischemic preconditioning to inhibit the release of endogenous catecholamine from the ischemic heart was tested to investigate the probable cardioprotective mechanism of ischemic preconditioning. METHODS: In the isolated, Langendorff perfused rat hearts, we observed the protective effect of ischemic preconditioning against post-ischemic reperfusion injury, and measured the amount of catecholamine released into coronary effuent. In addition, we observed the effect of catecholamine depletion on reperfusion injury in non-preconditioned and preconditioned hearts. RESULTS: During the reperfusion(20min) after ischemia(30min), the cardiac function was markedly depressed with the development of severe contracture. In the heart preconditioned by three sequential episodes of 5min ischemia and 5min reperfusion, the reperfusion contracture decreased significantly and the cardiac function was almost recovered to normal after 20min reperfusion. The release of lactate dehydrogenase was also decreased in the preconditioned heart. The release of endogenous catecholamine was abruptly increased immediately after the reperfusion and the release was exponentially decreased throughout the reperfusion period. THe pattern of catecholamine release was much different from that of lactate dehydrogenase release. In the preconditioned heart, the release was significantly decreased to about half of that in non-preconditioned t\heart. Endogenous catecholamine depletion by reserpine treatment did not affect the post-ischemic functional recovery in both non-preconditioned and preconditioned hearts. CONCLUSION: It is suggested from these results that ischemic preconditioning inhibis the release of endogenous catecholamine during ischemic period, which may be partly related to cardioporotective effect of preconditioning in ischemic and reperfused heart.

The authors evaluated the clinical significance of the bilirubin values as screening test means for predicting the occurrence of neonatal jaundice earlier after birth, by using the transcutaneous bilirubinometry which is known to measure the bilirubin values in a noninvasive, accurate and simple way. The results obtained were as follows: 1. In comparison between the test group(showing the symptom of a jaundice within 72 hours after birth) and the control group, there were found no statistically significant differences in terms of sex, delivery type, birth weight, gestational age and mother's age, while being found statistically significant differences in terms of transcutaneous bilirubin at birth(TcBbirth), transcutaneous bilirubin at 24 hours after birth(TcB24hr), increase in transcutaneous bilirubin per hour during the first 24 hours after birth(TcBin/hr) and transcutaneous bilirubin at 72 hours after birth(TcB72hr)(p<0,05). 2. The correlation test using the Pearson's coefficient produced statistically significant correlationship between each transcutaneous bilirubin index (TcBbirth, TcB24hr, TcBin/hr and TcB72hr) and serum bilirubin concentration at 72 hours after birth(B72hr)(p<0.05), while the result of the correlation test using the Spearman's roh showed statistically significant correlationship only between TcB24hr or TcB72hr and B72hr(p<0.05). As it was, the correlationship between TcB72hr and B72hr was highest in both Pearsons coefficient and Spearman's roh tests, followed by that between TcB24hr and B72hr. 3. In view of the ROC graph, the most effective means of predicting the occurrence of the neonatal jaundice was TcB72hr followed by TcB24hr, TcBbirth and TcBin/hr in their order. In particular, TcB24hr was conceived to be useful as screening test for determining an early discharge from the nursery within 48 hours. On the other hand, since the negative predictive value of TcBbirth, and TcB24hr is higher, the possibility that those infants showing a lower value of these indices may well be free later from a serious neonatal jaundice even if they should be discharged earlier from the nursery. In conclusion, those four indices predicting the neonatal jaundice in a simple, quick and noninvasive manner using the transcutaneous bilirubinometry were considered to be effective screening test means whereby any serious neonatal jaundice developed earlier after delivery can be successfully predicted.

Diffuse neonatal hemangiomatosis is an uncommon disease that is characteristed by a diffuse nature of the lesions, and distinguished form a single or few, or superficial or deep, capillary, cavernous, or mixed hemangiomas occuring in early or adult life. We report an autopsy case of multiple hemangiomatosis, which is associated with massive osteolysis of right humerus and arteriovenous fistulae in surrounding soft tissues. The patient is a 23 day old female infant and had a 2.0x1.5 cm sized cystic destructive bony lesion which was located in the proximal shaft of right humerus. Right arm was hypertrophied, compared to the normal looking left. There were multiple hemangiomas in right humerus, lung, cutaneous skeletal muscles and nerves. This case shares clinical characteristics of Gorham's disease.
