Analysis of the Neurospora crassa genome data reveals at least 14 proteins that contain tetratricopeptide repeat (TPR) motifs. One of them shows over $60\%$ homology with SSN6 of Saccharomyces cerevisiae, a global repressor that mediates repression of genes involved in various cellular processes. Sequence analysis of its cDNA shows that it encodes a putative 102kDa protein. Mutant strains generated by RIP (repeat induced point mutation) process show four distinctive patterns of vegetative growth at various rates. They are male-fertile, yet all female-sterile and produced little or no perithecium. These results indicate that this gene is pleiotropic and involved in several cellular processes of vegetative growth, conidiation and sexual cycle. It is designated rcm-1(regulation of conidiation and morphology).

This paper proposes a new syndrome-testable design method for large MOSPLA's. In the conventional syndrome test method, the testing array circuit for testability is added but it has the defect that the circuit gives effect on the normal operation of the basic PLA circuit. Therefore, by adding the shift registers to the product lines of the basic MOSPLA's this defect is eliminated and the number of test patterns is decreased. In order to reduce the number of fault free syndromes to be predetermined, also, one output line, which is connected to all product lines is added. Therefore the number of output lines be observed is decreased. And the analytical method to compute fault free syndromes is presented. By unsing this method, the time and the effort to compute the syndromes are decreased.

The purpose of this paper is to compare two approach to assessment of coping patterns. The sampling method was a purposive sampling technique. The study participants were out patients 113 of rheumatoid arthritis center of one University hospitals in Seoul. Datas were collected from Nov. 13 to Nov. 24, 1995. The instruments used for this study were Graphic Rating Scales of pain, The Beck Depression Inventory and Coping Patterns tool. The collected data were analyzed for frequency, means, SD, factor analysis., Pearsons' correlations and ANOVA. The results were summerized as follows ; 1. When raw scores were used : there were not correlation in all three coping patterns. 2. When relative scores were used : there were significantly correlated in all three coping patterns. 1) Active coping and Positive-cognitive coping (r=-0.352, p< 0.0001) 2) Positive-cognitive coping and Negative-cognitive coping (r=-0.594, p< 0.0001) 3) Active coping and Negative-cognitive coping(r=-0.544, p< 0.0001) The results of this research with relative scales provided more insight into the correlation in all three coping patterns. 3. Pearsons' Correlations were computed for each coping pattern, age, pain level, duration of pain and BDI. 1) Using raw score : (1) Active coping was significantly related to pain level(sensory score ; r=0.268, p<0.05, affective score ; r=0.266, p< 0.05) (2) Positive-cognitive coping was significantly related to age (r=-0.252, p< 0.05), pain level (sensory score ; r= -0.244, p< 0.05) (3) Negative-cognitive coping was significantly related to depression level (r=0.312 p< 0.0001). 2) Using relative score (1) Active coping was significantly related to pain level(sensory score ; r=0.299, p<0.05, affective score ; r=0.246, p< 0.05) (2) Positive-cognitive coping was significantly related to age (r= -0.187, P< 0.05), pain level (sensory score ; r=-0.317, p<0.0001, affective score : r=-0.305, p<0.0001) and depression level(-0.339, p<0.0001)) (3) Negative-cognitive coping was significantly related to depression. level(r=0.313, p<0.0001). 4. When raw and realtive coping scores were compared to those of age groups, religious groups and BDI level(high, middle, low) ; 1) Using raw score : (1) Active coping : there were not significantly difference (2) Positive-cognitive coping ; 20-39 age group and 50-59age group had significantly higher scores than over 60age group. BDI-low level group had significantly higher scores than other groups. (3) Negative-cognitive coping : 20-39age group and over 60age group had significantly higher scores than 40-49age group. Non-religious group had significantly higher scores than christian group. BDI-high level group had significantly higher scores than other groups. 2) Using relative score : (1) Active coping : over 60 age group had significantly higher scores than 20-39 age group and 40-49age group had significantly higher scores than 20-39 age group (2) Positive-cognitive coping ; 40-49age group, 20-39age group and 50-59age group had significantly higher scores than over 60age group. Christian group had significantly higher scores than non-religious group. BDI-low level group had significantly higher scores than other groups. (3) Negative-cognitive coping ; Non-religious group had significantly higher scores than christian group and buddhistic group. BDI-high level group had significantly higher scores than other groups. The current data suggest that relative scores may yield a different perspective on coping patters than raw scores. The use of relative scores reveals the relation clearly, without its being blurred statistically by the effect of other coping strategies or being relegated to a partial correlation. The use of relative scores holds promise for delineating the relations between ways of coping and health-related behavior.

The records of 10 patients with traumatic diaphragmatic hernia seen from November 1977 through July 1987 were reviewed. All the patients had a transdiaphragmatic evisceration of abdominal contents into the thorax. We treated 7 male and 3 female patients ranging in age from 3 to 62 years. In 8 patients, diaphragmatic hernia followed blunt trauma and in 2 patients, stab wounds to the chest. The herniation occurred on the right side in 3 patients and on the left side in 7. All the patients sustained additional injuries: rib fractures [7 patients], additional limb, pelvic and vertebral fractures [6], closed head injury [2], lung laceration [1], liver laceration [1], renal contusion [1], ureteral rupture [1], and splenic rupture [1]. Organs herniated through the diaphragmatic rent included the omentum [6 patients], stomach [4], liver [4], colon [3], small intestine [1], and spleen [1]. For right-sided injuries, the liver was herniated in all 3 patients and the colon, in 1. in the initial or latent phase, dyspnea, diminished breath sounds, bowel sounds in the chest were noted in 4 patients, and in the obstructive phase, nausea, vomiting, and abdominal pain were found in all 3 patients. Two patients had a diagnostic chest radiograph with findings of bowel gas patterns, and an additional 8 had abnormal but nondiagnostic studies. Hemothorax, pleural effusion or abnormal diaphragmatic contour were common abnormal findings. Three patients were operated on during the initial or acute phase [immediately after injury], 4 patients were operated on during the latent or intermediate phase [3 to 210 days], and 3 patients were operated on during the obstructive phase [10 to 290 days]. Six patients underwent thoracotomy, 2 required thoracoabdominal incision, and 2 had combined thoracotomy and laparotomy. Primary suture was used to repair the diaphragmatic hernia in 9 cases. One patient required plastic repair by a Teflon felt. Empyema was the main complication in 2 patients. In 1 patient, the empyema was treated by closed thoracostomy and in 1, by decortication and open drainage. There were no deaths.

Objectives: The purpose of this study was to examine the relationship between pathological patterns and hyperventilation syndrome, using pathological pattern and Nijmegen questionnaires. Methods: 33 healthy adults were asked to complete the Cold-Heat-, Phlegm-, Yin deficiency, and Lao Juan (勞倦)-pattern questionnaires, the Chalder fatigue scale, and the Nijmegen questionnaire at Kyung Hee University Hospital. We performed Pearson correlation analyses between the pathological pattern questionnaires and the Nijmegen questionnaire. The questionnaires were composed of several factors. Therefore, each factor and Nijmegen questionnaire score were also analyzed. Results: All of the pattern questionnaire scores had a positive correlation with the Nijmegen questionnaire score. The phlegm pattern, in particular, and the LaoJuan (勞倦) questionnaire scores had high correlation coefficients. The coefficient for the phlegm pattern was 0.856 and the coefficient for the LaoJuan (勞倦) pattern questionnaire was 0.855. Conclusions: The results mean that the pathological pattern questionnaires could be one of the reference materials to evaluate hyperventilation syndrome. Furthermore, improvement of pathological patterns may be helpful for treating hyperventilation syndrome, together with conventional therapies including breathing training.

The purposes of this study were to analyze the muscle activities and the characteristics of muscle recruiting patterns of upper trunk for Ssirum dutguri technique using three top-ranked elite Ssirum players. The EMG technique was used to record muscle activities of both right and left sides of latissimus dorsi, biceps brachii, and erector spinae. Six surface electrodes were placed on the surface of the selected muscles and one ground electrode was also attached on the back of neck(C7). One video camera was also used to record the Ssirum motion to define 4 events and 3 phases for further analysis. The raw EMG data were filtered with band pass filter (50-400 Hz) to remove artifacts and then low pass filtered (4 Hz) to find the linear envelope which resemble muscle tension curve. This filtered EMG data were normalized to MVIC for the purpose of comparion between the subjects. The results were indicated that each subject with different physical characteristics showed very different muscle activity patterns. Although Ssirum dutguri is considered as foot technique the player grasped opponent's satba(belt) with both hands when they play. Because of this reason, activities of upper trunk muscles were relatively high. However, direct comparison between upper and lower body muscles was not possible due to the lack of the data in present study. Interestingly, all threes subjects showed that erector spinae muscle activity was comparatively higher than those of latissimus dorsi and biceps brachii. This implies to reinforce back muscle as a routine of training to improve performance or to prevent back injury.

The purpose of this study was to evaluate the fracture resistance of tooth restored with gold inlay. A profound understanding of the isthmus width factor, which is one of the several parameters of cavity designs, would facilitate the appropriate cavity preparation in a specific clinical situation. In this study, the cavities for gold inlay were prepared in maxillary left first premolar. A three-dimensional model was designed using I-DEAS program. The model was composed of 2515- nodes and 2172 isoparametric brick elements. In the model isthmus width was varied into 1/4, 1/3 and 1/2 of intercuspal width respectively, and numeric values of the material properties of enamel, dentin and gold was set. Three types of load : concentrated load, divided load and distributed load was 500N. The empty cavities in the model were also examined using divided load and distributed load. The three - dimensional Finite Element Method was used to analysis the displacement and stress distribution. The results were as follows : 1. All of the experimental models which were filled with gold inlay revealed similar direction of displacement to that of the natural tooth model under the same load type. But in the models with empty cavities, as the isthmus width increased, the degree of displacement increased in the case of divided load type. 2. All experimental models which were filled with gold inlay showed stress concentration at load points, but in the models with empty cavities at divided load type, as isthmus width increased, stress was concentrated at the comer of the pulpal floor. 3. In the models with empty cavities at divided load type, tooth fracture was expected regardless of isthmus width, but all experimental models which were filled with gold inlay after cavity preparation were not susceptible to fracture. 4. In all experimental models which were filled with gold inlay after cavity preparation, displacement patterns were similar under both concentrated and divided load types. In the models with empty cavities, a divided load resulted in a bucco-lingual cuspal displacemenat in both sides, but a distributed load resulted in a lingual displacement of the tooth.

Between April 1986 and September 1990, 34 patients with a single or dominant right ventricle underwent modified Fontan procedure for definite palliation in Seoul National University Children`s Hospital. Their age at operation ranged from 8 months to 14 years [Mean 5.5 years]. The ventricular chamber was solitary and of indeterminate trabecular pattern in 6 patients. 28 patients had posteriorly located rudimentary chamber, all of which were trabecular pouches having no communication with outlet septum. The patterns of atrioventricular connection were common inlet[9], double inlet [11], left atrioventricular valve atresia [12] and right atrioventricular valve atresia with L-loop [2]. Pulmonary outflow tracts were atretic in 7 patients and stenotic in 26 patients. Major associated anomalies included anomalous systemic venous drainage [15], dextrocardia [12] and total anomalous pulmonary venous connection[3]. Shunt operations were previously performed in 13 patients and pulmonary artery banding and atrial septectomy in 1 patients. Surgery included intraatrial baffling in 26 patients, bidirectional cavopulmonary shunt in 13 patients, atrioventricular valve obliteration in 3 patients and atrioventricular valve replacement in 3 patients. Central venous pressure measured postoperatively at intensive care unit ranged from 18cm H2O to 28cm H2O [mean 23.2cm H2O]. Hospital mortality was 35.3% [12/34], all died out of low output syndrome. Suspected causes of low output syndrome include ventricular dysfunction [8], hypoplastic or tortuous pulmonary artery [2] and elevated pulmonary vascular resistance [2]. 19 patients had 31 major complications including low output syndrome [18], arrhythmia [4], acute renal failure [3] and respiratory failure [3]. Mortality rate was significantly higher in the groups receiving intraatrial baffling and AV valve replacement respectively [p<0.05]. 20 patients were followed up postoperatively with the mean follow-up period 15.0$\pm$11.6 months. There were no late death and follow-up catheterization was performed in 10 patients. Mean right atrial pressure was 15.4$\pm$6.8mmHg and ventricular contraction was reasonable in all but one case. Thus, Fontan principle can be applied successfully to all the patients with complex cardiac anomaly of single ventricle variety and better results can be anticipated with judicious selection of patient and improvement of postoperative care.

This paper deals with the distribution, reservoir and mode of spread of infection on 6 hatcheries in Taegu, Kyungpook and 5 broiler farms in Kyungpook during the period from June 1991 to June 1992. Isolated Salmonella were examined for serotypes, biotyping of Salmonella(S) typhimurtum, antibiotic susceptibility and some biochemical characteristics. Forty two Salmonella strains were isolated from 42(2.7% of 1,577 caecal samples of chicks, and their serotypes were S typhimurium 10, S typhimurium var Copenhagen 5, S infantis 4, S thompson 3, and untypable 20. The isolation rate of Salmonella varied from 0 to 5.1% in 6 hatcheries and that of Salmonella from 5 broiler farms was 10. 5%. Biotypes of 10 S typhimurium and 5 S typhimurium var Copenhagen strains isolated from chicks of hatcheries and broiler farms were biotype 2(86.6%), 8(6.7%), and 10a(6.7%), and 26i(6.7%) according to Duguid's scheme. Antibiotic susceptibility test of Salmonella isolated were performed by agar dilution method, using 9 antibiotics as follows: ampicillin(Am), chloramphenicol(Cm), gentamicin(Gm), kanamycin(Km), nalidixic acid(Na), rifampicin(Rf), streptomycin(Sm), sulfadimethoxine(Su), and tetracycline(Tc), All the strains were sensitive to RF. But 8 strans(23.8%) were resistant to one or more drugs and the most common resistance patterns of transferred R plasmids were SmSuGm and SmSu. Among 42 isolates, one had transferable citrate utilizing plasmid. S typhimurium and S typhimurium var copenhagen strains were resistant to killing by 90% normal guinea pig serum.
