Pt was deposited on carbon support by chronoamperometry. The catalytic activity for methanol oxidation was checked by CV (cyclic voltammetry) method. The amount of Pt loading was calculated by integration of I-t curve obtaining the total current used for the Pt deposition. The ECA (electrochemical active surface area) for loaded Pt was calculated from the hydrogen adsorption/desorption peaks in 0.5 M H₂SO₄solution. Pt was deposited on clean carbon electrode surface with various concentration of Pt solution (0.1 mM) was used. As the concentration of Pt increased, the specific catalystic activity of Pt decreased suggesting that, in the electrochemical reaction of Pt ion with electrode surface, Pt particles were smaller and more dispersed in low concentration of Pt solution. With this condition (0.1 mM Pt), Pt was electrodeposited on a commercial carbon support, Vulcan XC-72. Electrochemically loaded Pt catalyst had the higher ECA, and showed higher specific catalytic activity for mathanol oxidation than a commercial Pt/C catalyst.

심내막상 결손증(Endocardial cushion defect)은 선천성 심장기형의 약 3% 정도를 차지하는 비교적 드문 질환이며, 복잡한 동반 기형을 나타내고 있고, 그 수술 방법에 있어서도 많은 논란이 있으며, 사망율도 높은 질환인 바, 저자들은 지난 1년간에 3예의 본 증례에 대한 수술 치험에서 술후 3∼6개월간에 만족할만한 임상적 추적 결과를 얻었기에 보고하는 바이다. In Pusan Paik Hospital, Inje Medical College, there were two complete endocardial cushion defects (ECD) and a partial one, which were successfully repaired in 1986. In a patient of partial ECD, primum atrial septal defect was closed with pericardial patch. In a patient of complete ECD, associated with secundum ASD, pulmonary stenosis and Down's syndrome, the atrial and ventricular septal defects were closed separately with bovine pericardium and Dacron patches respectively, and then pulmonary stenosis was relieved by transannular patch widening in addition to valvotomy and infundibulectomy. In another patient with complete ECD, small interventricular communication was closed with simple suture with pledget, and primum ASD closed with pericardial patch. In all patient, the mitral clefts were closed with three or four 5-0 Prolene interrupted sutures. Transient A-V dissociation developed postoperatively in two patients, and heart failure in complete ECD with Down's syndrome was overcome with medical treatment.

A successful treatment of infants and children with congenital heart defects depends upon several factors: diagnosis must be accurate, the operative technique, including techniques of perfusion and myocardial preservation, must be suited to the needs of patients and intensive cares, including accurate anesthesia, must be applied through all stages of investigation and treatment, i.e. before, during and after the operation. Recently we performed a open heart surgery successfully for a six-years old girl who had suffered from frequent upper respiratory tract infection and mild to moderate exertional dyspnea with congenital heart defects (ventricular septal defect, Kirklin type II, with patent foramen ovale). The operation and postoperative course were very smooth. And now we report this with review of literatures.

Purpose: This study was to explore the relationship between personality type and learning attitude and academic achievement of nursing students. Method: 91 students were sampled from freshman in nursing school. Data were collected from April 2 to October 5 2007. Analysis of the results were carried out using SPSS win 12.0 for frequency, mean and standard deviation, t-test, ANOVA, Pearson correlation. Result: The result of MBTI test was that nursing students in this study showed extraversion(52.7%), sensing(82.4%), thinking(56.0%), judging(57.1%). Academic achievement according to personality was that only feeling(F) type students had significantly higher score of English than thinking(T) type students(p=.013). Learning attitudes according to personality were that sensing(S) type students had significantly positive attitude toward their college than intuition(N) type students (p=.016). And think(T) type students had significantly higher confidence of learning than feeling(F) type students. There was significant positive correlations between learning method and score of English, Fundamental Nursing, Anatomy(p<05). Conclusions: Diagnosing personality can differentiate student's learning attitude. It is important to develop teaching-learning strategies according to their personality, which can help them to improve their academic achievement.

The authors reviewed 24 Patients with brain abscess from January 1986 to December 1990. The male to female ratio was 16:8 and most frequently developed at second decades. The commonest cause was chronic ear infection with abscess in the temporal lobe, and common organism was proteus species. All patients received a total of 6 weeks of antiobiotic therapy. Surgery was performed in 24 patients. Drainage of drainage and later capsulectomy may offer a simple, safe and easy removal of capsule. There was no postoperative death or empyema. The most important predictor of outcome was the patients condition when first seen. Early specialist care, computerized tomography, correct choice and dosage of antibiotics, and the surgical methods in present use should make this a benign disease.

To evaluate the specificity of restriction fragment length polymorphism (RFLP) of Newcastle disease virus (NDV) fusion (F) protein gene for various NDV strains. F protein genes of NDV CBP-1 isolate, LaSota, B1 and Kyojungwon (KJW) were amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) and RFLP were examined. In RT-PCR using F primer sets for 1.7 kb F gene, the amplified products were observed in CBP-1, LaSota and B1 except KJW. However, F2 primer set for 521 bp yielded the amplified bands with all strains. The amplified F genes (1.7 kbp) were treatd with 15 different restriction enzymes to analyze RFLP and the cleavage patterns. CBP-1 showed various cleavage patterns with 8 enzymes, LaSota, with 11 enzymes and B1, with 11 enzymes. According to the cleavage patterns, the physical maps were constructed, and it was found that CBP-1, LaSota and B1 strains had specific cleavage sites with HinfI, XbaI and XhoI. These findings suggest that RFLP are worth applying in the diagnosis and molecular epidemiological studies of Newcastle disease.
