The purpose of this research is to maximize the core competencies by objectively measuring the Behaviour Patterns of students in Comic-Animation major to understand the difference between individuals and to maximize one's merits which will improve the efficiency in education. Also through this research we could understand which aspects would be affected in both the satisfaction about the major based on Behaviour Patterns and the satisfaction of university life. According to the DISC Patterns, 41.7% of the students in Comic-Animation department shows that they were in Patterns I (Influence). And Patterns S (Steadiness) were 10% which was the lowest percentage in this survey. In the average of the subject's satisfaction aspect, the satisfaction of the professors' suggestion was 3.68 which was the highest. While the satisfaction of the administration service and welfare facility was 2.56 which was the lowest. The satisfaction rate based on DISC Behaviour Patterns shows a significant difference among the satisfaction of the department, the satisfaction of atmosphere in university and the satisfaction of the admin and welfare. Patterns I (Influence) was the highest the satisfaction in the major and the satisfaction of the university life while Patterns C(Criticalness) was the lowest. In particular, the importance of the I (Influence) is the most important factor, but it is essential that there is a slight decrease in the precision and accuracy of the work, and C(Criticalness) is shy and stressed, so they need to give positive communication and accurate advice. It is required to Comic-Animation department professor to analyse students' character based on Behaviour Patterns and a person's pros and cons for the career exploration and the employment consultation in order to have positive affect on employment rate. Also if the department's Behaviour Patterns construction were well utilized, it can improve the success rate of useful leadership and fellowship. it will improve the atmosphere in the department which will decrease the drop-out rate but increase the cohesion in the department which will lead to providing better result in the work and the project.

Background: Corticosteroid is most potent and effective anti-inflammatory medication currently available and inhaled form has been used in the long-tenn control of asthma. Fluticasone propionate(Flixotide/Flovent: FP) is highly potent and topically active inhaled corticosteroid and has at least twice the potency of beclomethasone dipropionate(BDP) in the control of asthma. The aim of this study was to compare the efficacy of FP and BDP in several aspects. Method: Fifty patients with asthma were treated in a randomized, parallel group study of 4 weeks duration. During 2-week run-in period $\beta_2$-agonist was administered. After run-in period, FP $500{\mu}g/day$ was administered via Diskhaler or BDP $800{\mu}g/day$ via reservoir dry-power device. During the run-in and treatment period, morning and evening peak expiratory flow rate(PEFR) were measured daily. Daytime and nighttime asthma symptoms, daytime and night-time rescue bronchodilator use were checked daily. $FEV_{1.0}$ and FVC were measured biweekly in both groups. Results: Three patients treated with FP and seven patient treated with BDP were dropped out. Therefore forty patients completed the study. Morning and evening PEFR was increased and diurnal variation of PEFR decreased significantly in both groups. $FEV_{1.0}$ increased significantly in FP treatment group but not in BDP group. There were also improvements in daytime and night-time asthma symptoms, daytime and night-time rescue bronchodilator use in both groups after treatment There were no significant difference between groups in any of the efficacy parameters. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP. Conclusion: In this study, $500{\mu}g/day$ fluticasone propionate was as effective as $800{\mu}g/day$ beclomethasone dipropionate in the control of asthma. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP without adverse effect.

The present study was carried out to investigate the preventive effects of lamprey oil and corn oil on atherosclerotic rats induced by oral administration of cholesterol and vitamin $D_2$. The obtaind results were summarized as fellows; 1. The group, fed only the mixture of cholesterol and vitamin $D_2$ showed the significant increase of total lipid, total cholesterol phospholipid, LDL&HDL-cholesterol in the serum, triglyceride and cholesterol in the heart and the aorta, but the significant decrease of triglyceride in the liver, as comparing with normal control group (p<0.05). The aorta showed the severe damage of disorganization, calcification, necrosis and lipid deposition in the aortic wall. 2. The group, adminstered the mixture of cholesterol and vitamin $D_2$ and fed 15% lamprey oil diet, showed the significant decrease of total lipid, triglyceride, total cholesterol, phospholipid and LDL&VLDL-cholesterol in the serum, triglyceride and cholesterol in the heart and the aorta, but the significant increase of cholesterol in the liver, as comparing with atherogenic control group (p<0.05). The aorta showed slight calcification and no lipid deposition in the aortic wall as comparing with atherogenic control group. 3. The group, administerd the mixture of cholesterol and vitamin $D_2$ and fed 15% corn oil diet, showed the decrease of total lipid, triglyceride and VLDL-cholesterol in the serum, and triglyceride in the heart and the aorta, as comparing with atherogenic control group (p<0.05). The aorta showed calcification and no lipid deposition in the aortic wall. In reviewing above results it was concluded that lamprey oil and corn oil in polyunsaturated fatty acids had the preventive effect on atherosclerotic rats induced by cholesterol and vitamin $D_2$. And the effect of lamprey oil in n-3 polyunsaturated fatty acids was higher than that of corn oil rich in n-6 polyunsturated fatty acids.

The effect of intravesical formalin instillation as a therapeutic modality for intractable bladder hemorrhage is well known. And despite clear evidence of therapeutic efficacy of intravesical cytotoxic drugs and/or BCG immunotherapy, there have been substantial recurrences during followup after transurethral resection for superficial bladder tumor. If formalin injected at the bed of superficial bladder tumor is able to coagulate and necrotize the tumor, it will be greatly helpful to the patients With recurrent bladder tumor developed during followup. Since this technique is applicable on outpatient basis, an economical as well as a psychological burden of the patients can be reduced considerably. The purpose of this study is to evaluate the effect of submucosal formalin injection on rat bladder wall, 36 healthy adult male Sprague-Dawley rats (weighing 350gm in average) were divided into 3 groups: In Group I (control group), 0.01ml of normal saline was injected submucosally at the left posterolateral wall of the bladder opened under intraperitoneal Nembutal anesthesia ; In Group II and III, 0.01 ml of 10% and 4% formalin, respectively, were administered at the same site as in the Group I, two rats in each group were sacrificed at day 1, 2, and 3, and week 1, 2 and 4 after injection, respectively. Gross and microscopic examination of the cystectomized specimen were done in each group. In the Group II, bladder stones were formed at week I, and in both the Group I and III, stones were seen at week 2 post injection. There was no significant difference III histologic findings of the bladder between the group II and III. Mucosal ulcer and/or prominent mucosal disruption was observed at 24 hours after injection in both Group II and III. Epithelial regeneration began at day 2, and was marked at day 3, and epithelial lining was almost normalized one week after injection. Subepithelial edema, telangiectasia and inflammatory reaction were prominent at 24 hours post formalin injection. Subepithelial edema persisted in moderate degree for 1 week. Telangiectasia and inflammatory reaction were noted for 4 weeks. Mild degree of these findings also appeared In the control group. Fibroblastic proliferation appeared at day 2 and persisted in moderate degree for 4 weeks. There has been no mortality or bladder perforation. These results suggest that clinical application of this technique is feasible for the selected cases of recurrent, solitary superficial bladder tumor. However, optimal dosage of formalin in relation to the size of the lesion remains to be investigated.

Since the summer of the year 1972 ulcer disease of common carp, colour carp ana goldfish had suddenly spread widely and caused a serious mortality at fish farms especially around Gim-hae and Yang-san, near Busan. The present study aimed to find out the causative organisms, histopathological changes and the way of treatment, and the results are summarized as follows : Two kinds of pathogenic bacteria, i. e, Chondrococcus columnaris and Aeromonas sp. were isolated from the mucus of the lesion. According to the macroscopic findings, these symptoms began with the hemorrhagic spots under scales which fell out, after the collapse of the dermis, which was followed by lesion to form ulcer, and then the muscle was exposed. The fin was eroded mostly from the distal part, but sometimes from the basal part. Gills showed grey colour, and this part of the tissue collapsed. According to the histopathological findings, the dermis was exposed after the collapsed of the epithelium of the skin, and the necrosis of the musculature occurred, the muscular fibre being destroyed. The epithelial cells of gill tissue proliferated, thus gill filaments were conglutinated and collapsed. Fatty degeneration happened at the liver but the other organs seem to be normal. Treatment with the following mixtures were effective the water temperature of $22\~25^{\circ}C$, but not effective when the temperature was under as low as $13\~15^{\circ}C$. Mixture 1. Aivet (HB-115.HCI) 0.3ppm Malachite green 0.2ppm. Dipterex 0.4ppm Mixture 2. Furanace (P-7138) 0.05ppm Malachite green 0.2ppm Dipterex 0.4ppm When lesion healed, the epithelium, dermis, and the muscular fibre were regenerated.

Background: Primary goal of anticoagulation treatment in patients with mechanical heart valve is the effective prevention of thromboembolism and safe avoidance of bleeding as well. Material and Method: Two-hundred and nine patients with the St. Jude Medical prosthesis operated on between 1984 and 1995, for mitral(MVR 122), aortic(AVR 39) and double mitral and aortic valve replacement(DVR 48) respectively, were studied on the practically achieved levels of anticoagulation and the clinical outcomes. Patients were on Coumadin and followed up by monthly visit to outpatient clinic for examination and prothrombin time measurement to adjust the International Normalized Ratios(INRs) within the low-intensity target range between 1.5 and 2.5. Result: A total anticoagulation follow-up period was 1082.0 patient- years(mean 62.1 months) and INRs of 10,205 measurements were available for evaluation. The accomplished INRs among the replacement groups were not significantly different and only 65% of INRs were within the target range. And, in individual patients, only 37% of patients had INRs included within the target range in more than 70% of tests during follow-up period. The levels of INRs in patients with atrial fibrillation, which was found in 57% of patients, were definitely higher than the ones measured in patients with regular rhythm(p<0.001). Thromboembolisms were experienced by 15 patients with the incidence of 1.265%/patient- year(MVR 1.412%, AVR 0.462% and DVR 1.531%/patient-year) and major bleeding by 4 patients with the incidence of 0.337%/patient-year(MVR 0.424%, AVR none and DVR 0.383%/patient-year). Frequent as well as prolonged missing of prothrombin time tests was the main risk factor strongly associated with the thromboembolic complications(odds ratio 1.99). The proportion of INRs within target range of less than 60% in individual patient was the highly significant risk factor of both thromboembolic and overall embolic and bleeding complications(p<0.004 and p<0.002 respectively). Conclusion: In conclusion, the low-intensity therapeutic target range of INRs was adequate in patients with AVR and in sinus rhythm. However, the patients with replacement of the mitral valve were more likely to require higher target range of INRs, especially in the presence of atrial fibrillation, to achieve the practical levels of anticoagulation enough to prevent thromboembolic complications effectively. For the higher therapeutic target range of INRs between 2.0∼3.0, further accumulation of clinical evidences are required. It is highly desirable to improve the patients' compliance under continuous instructions in visiting outpatient clinic and in taking daily Coumadin without omission and to keep INRs consistently within optimal range with tight control for minimization of chances and of periods of exposure to the risk of complications. And, particularly, patients with high risk of complications and with wide fluctuation of INRs should be better managed with frequent monitoring anticoagulation levels.

Background: It has been well known that bronchial asthma is a chronic inflammatory disorder. The "activation" of lymphocytes has a significant role in the pathogenesis of bronchial asthma. Among these lymphocytes, TH2-like rather than TH1-like lymphoytes are activated in the bronchial tissues from patients with atopic bronchial asthma. However, the difference of cytokines expression is not well documented between the atopic normal subjects and atopic asthmatics. Methods: Bronchial tissues were obtained from the tweleve atopic and non-atpoic asthmatics and tweleve atopic and non-atopic healthy subjects for in stiu hybridizatin of IL-2, IL-4, IL-5, and INF-$\gamma$. The probe of cytokines were tagged with digoxigenin by random priming method. Results: The infiltration of many inflammatory cells on submucosa and denuded epithelium were observed in the bronchial tissue from patients with bronchial asthma. The RNase-treated bronchial tissues did not have the brown signal on the tissue, but, RNasc-untreated bronchial tissues had the positive brown signal on the inflammatory cells under the basement membrane. The IL-2 positive signals were detected in 2 cases, IFN-$\gamma$ in 1 casc, IL-4 in 2 cases, IL-5 in 2 cases among 6 non-atopic healthy subjects. The atopic healthy subjects showed 1 case of positive signal of IL-2 and IFN-$\gamma$, but did not show any signals of IL-4 and IL-5. The positive signals of IL-2 were detected in 4 cases among 6 atopic and 6 non-atopic asthmatics, 2 cases and 1 case of IFN-$\gamma$ respectively, 4 cases and 3 cases of IL-4 respectively, 4 cases and 3 cases of IL-5 respectively. Conclusion: The lymphocytes were activated in the bronchus of asthmatics. Among lymphocytes, TH2-like lymphocytes may be involved in the pathogenesis of bronchial asthma. However, futher study with immunohistochemical stain may be necessary for defining the source of cytokines, because of TH2-like lymphocytes were also activated in some atopic healthy subjects.

Background: Although pulmonary tuberculosis is effectively controlled with 6 months or 9 months short course standard regimens, comparable numbers of treatment failures ensued because of inadequate treatment mainly due to patient's poor compliance. Indequate treatment with standard regimens during initial treatment may cause emergence of drug resistance and prolong the duration of chemotherapy. Also it may make the patient lesser compliant and finally increase the morbidity and the mortality. Methods: A clinical study was done to evaluate clinical and bacteriological characteristics of 94 patients who were retreated for pulmonary tuberculosis. Results: 1) 62 of the 94 patients were male and 32 patients were female. Mean age is 51 years old in male and 45 years old in female. 2) The extent of the disease on the chest radiograph was minimal in 10(11.1%) patients, moderate in 31(33.3%) patients, and far advanced in 52(55.6%) patients. 3) On sputum bacteriologic examination, 73(77.7%) patients were positive in sputum AFB smear and/or culture for Mycobacterium tuberculosis. 4) Results of drug sensitivity test performed in 42 patients showed that the resistance to one drug is in 9(20.5%) patients, two drugs in 18(40.8%) patients, and more than three drugs in 14(31.8%) patients. 5) Poor patient's compliance was the leading cause of the retreatment of pulmonary tuberculosis(43.6%) 6) Only 24(25.5%) patients of the 94 retreatment patients were successfully treated and 39(41.6%) patients were dropped out during follow-up. Conclusion: We concluded that poor patient's compliance was the most important cause of treatment failure not only in primary treatment patients but also in retreatment patients. Primary treatment of pulmonary tuberculosis should be completed under strict monitoring of the patient because significant number of retreatment patients had multiple drug resistance and poor outcome.

This study will evaluate the effectiveness of various pretreatments when fiber-reinforced composite (FRC) post is bonded to endodontically treated tooth with resin cement. Materials and methods: Canal shaping of FRC post (DT Light post, Size 3, Bisco Inc., Schaumburg, IL, USA) was performed on endodontically treated premolars at 1.5 cm from CEJ. Samples were divided into 6 groups of surface treatment after conventional washing and drying to the canal. Total of 24 FRC posts were randomly divided into 6 groups of surface treatment as follows: Group C: control - no surface treatment, Group A: airborne-particle abrasion (Cojet sand, 3M ESPE), Group S: silanization (Bis-silane, Bisco Inc.), Group M: universal primer (Monobond-plus primer, Ivoclar Vivadent Inc.), Group AS: silanization after airborne-particle abrasion, Group AM: universal primer treatment after airborne-particle abrasion. Pretreated fiber posts were cemented with resin-based luting material and photo-polymerized and cut to the thickness of 1 mm. Push-out test using a universal testing machine was performed. Bonding failure strength of post dislodgement was measured and the type of bonding failure was classified. Data were analyzed with Kruskal-Wallis test and multiple comparison groups were performed using Tukey HSD value of rank test (${\alpha}=0.05$). Results: Group AS showed significantly highest bonding strength. Group S, group AM, group A, and group M showed lower bonding strength in order. The control group showed the lowest bonding strength. Conclusion: Surface treatment with silane showed to be the most effective of the surface pretreatment methods for cementation of FRC post. Surface treatment with universal primer showed no significant difference compared with no surface treatment group as for bonding strength.

Purpose: Ischemic enterocolitis (IEC) is the total or partial infarction of the intestine in the absence of occlusion of a major mesenteric blood vessel. The purpose of this study was to evaluate the clinical features of IEC in children. Methods: A clinical analysis of 6 patients with IEC who were admitted to the Department of Pediatrics at Pusan National University Hospital, between 1996 and 2005 was conducted retrospectively. Patients were diagnosed with IEC based on clinical characteristics, including radiologic, endoscopic, histopathologic, and intraoperative findings. Results: Four boys and 2 girls between the age of 6 weeks and 6 years were included in this study. Most of the patients were born at term and had a birth weight that was appropriate for their gestational age. The major symptoms of IEC observed included hematochezia or hematemesis (5 cases), vomiting, diarrhea, abdominal pain or irritability (4 cases), as well as abdominal distension and fever (3 cases). IEC occurred in thecolon in 5 cases (2 descending colon, 1 descending and sigmoid colon, 1 sigmoid colon, 1 whole colon) and the duodenal bulb and gastric antrum in 1 case each. The type of the lesions observed includedulcera, which were found in 3 cases, perforation, which was pbserved in 2 cases, necrotic patches, which were observed in 2 cases, stricture, which was observedin 1 cases, and massive membranous desquamation of the epithelium, which was observed in 1 case. Two of the patients received surgical treatment and the remaining four were treated conservatively. None of the patients died. Conclusion: The presentation of IEC varies, and the findings of this study will be helpful in managing patients with IEC.
