  • The earlier KANSEI evaluation had to choose not to overlap the opposite meaning of the words, had to choose that some figures are shown step by step and had to choose be prepared things in advance. However, The Study shows a method which visualizes the imprecise evaluations of human without choosing evaluation items which are not prepared figures. The program is used the way which is entered by hand-drawing that the subjects use the way to enter their subjective feelings about the evaluations presented by using the mouse or the graphics tablet. It is possible to express imprecise things about evaluations and the method of drawing is free. The program provides that we can express our thinking by drawing and there are a few limits and the prescribed standard. The area ratio of each circle is expressed as a pie chart and the area of circle what is drawn which is counted automatically at the same time. These things are possible not only to modify a transparency, a thickness of a line, a color and the area of circle what is drawn, but also to adjust the area of circle. The conceptual model is visualized that expresses something by hand-drawing such as a circle. The conceptual model has wide range of applications such as a personnel evaluation, a suffering evaluation and product evaluation. The program currently has been testing the effective of the program's possibilities which is used with the personnel appraisal tool of the nurses themselves who work in nurse support department where the St. Marianna University School of Medicine Hospital is. And also the program is proceeding with development to visualize the conceptual model by dynamic interfaces effectively and the program is applied such as KJ method and a program is used to express the kind of the patient's pain and its level.

  • Background The combination of polycaprolactone and hyaluronic acid creates an ideal environment for wound healing. Hyaluronic acid maintains a moist wound environment and accelerates the in-growth of granulation tissue. Polycaprolactone has excellent mechanical strength, limits inflammation and is biocompatible. This study evaluates the safety and efficacy of bio-conjugated polycaprolactone membranes (BPM) as a wound dressing. Methods 16 New Zealand white rabbits were sedated and local anaesthesia was administered. Two $3.0{\times}3.0cm$ full-thickness wounds were created on the dorsum of each rabbit, between the lowest rib and the pelvic bone. The wounds were dressed with either BPM (n=12) or Mepitel (n=12) (control), a polyamide-silicon wound dressing. These were evaluated macroscopically on the 7th, 14th, 21st, and 28th postoperative days for granulation, re-epithelialization, infection, and wound size, and histologically for epidermal and dermal regeneration. Results Both groups showed a comparable extent of granulation and re-epithelialization. No signs of infection were observed. There was no significant difference (P>0.05) in wound size between the two groups. BPM (n=6): $8.33cm^2$, $4.90cm^2$, $3.12cm^2$, $1.84cm^2$; Mepitel (n=6): $10.29cm^2$, $5.53cm^2$, $3.63cm^2$, $2.02cm^2$; at the 7th, 14th, 21st, and 28th postoperative days. The extents of epidermal and dermal regeneration were comparable between the two groups. Conclusions BPM is comparable to Mepitel as a safe and efficacious wound dressing.

  • In order to study the range of flight and feeding activity of Anopheles sinensis, the dispersal experiment was conducted in Paju city, located in the northern part of Gyeonggi-do, Republic of Korea, during the period of 7th to 28th September 1998. Unfed females An. sinensis were collected in cowshed and released after being marked with fluorescent dye at 23:00 hours on the same day. Released female mosquitoes were recaptured everyday during 21 days using light traps, which were set at 10 sites in the cowsheds located 1, 3, 6, 9 and 12 km north-northwest and north-northeast and at 3 sites located 1, 6 and 9 km toward south-west from the release point. In addition, to study the longest flight distance in one night, we set the light traps at 16 and 20 km toward north-northeast from the release site. All the collected mosquitoes were placed on filter papers and observed on UV transilluminator after treatment with one drop of 100% ethanol. Out of 12,773 females of An. sinensis released, 194 marked females mosquitoes were recaptured, giving 1.52% recapture rate. Of 194, 72 mosquitoes (37 1%) were recaptured in light traps from three places set at 1 km from the release point, 57 mosquitoes (29.4%) from two places at 1-3 km, 41 mosquitoes (21.1%) from three places at 3-6 km, 20 mosquitoes (10.3%) from three places at 6-9 km, and 4 mosquitoes (2.1%) from two places at 9-12 km. Since 170 female mosquitoes (87.6%) out of 194 marked mosquitoes were captured within 6 km from the release point, this flight radius represents the main activity area. An. sinensis was found to be able to fly at least 12 km during one night.

  • This study was designed to assess the left ventricular peak systolic pressure/end-systolic volume (PSP/ESV) ratio in predicting symptomatic improvement with valve replacement in patients with aortic regurgitation and enlarged left von'lrlcular volume. We studied 21 patients (15 men and 6 women aged 15 to 60 years) with moderate or severe aortic regur- gitation, no other cardiovascular abnormalities and left ventricular end-systolic volume over 60 m11m2. In this group we assessed the preoperative variables which routinely were measured at cardiac catheterlzation to predict symptomatic improvement with valve replacement. Six months after operation, symptoms were alleviated in 13 patients(62%), and unchanged in 8()8%). By multivariate analysis, the PSP/ESV rati was a strong predictor for functional class 6 months after surgery(p=0.005) and also for change- in functional class prior to an operation to 6 months postoperatively(p=0.0)2). By 6 months after receiving valve replacement, all patients with a ratio over 1. 71 mmHglml/m'were in functional class I or II , in contrast, of those with a ratio < 1.71 mmHg/ml/m2, 40% were in functional class III. The PSP/ESV ratio may help to predict which patients with aortic regurgitation and enlarged left ven- tricular end-systolic volume will have symptomatic improvement with valve replacement.

  • We have experienced 62 cases of modified Fontan operations in Seoul Nat’l University Hospital from Apr. 1986 to Jul. 1989, They were 38 males and 24 females, and their age was ranged from 16 months to 15.5 years of age. [mean age : 5.73$\pm$2.99 years] There were 16 operative deaths and 2 late deaths, therefore 29% of overall mortality. Their diagnoses were as follows; 28 single ventricle, 11 tricuspid atresia, 6 DORV with LV hypoplasia, 3 pulmonary atresia with hypoplastic RV, 3 TGA with hypoplastic RV, 3 cor\ulcornerGA with hypoplastic LV and PA, 6 AV canal defects with PA, and 2 others. Low cardiac output and pleural effusion were developed frequently, so we divide 40 patients into some groups to analyze the physiologic and anatomic causes of them. By the degree of the LCO, group A was no LCO[mean amount of inotropics used: 0-5 \ulcornerg/kg/min] with 17 cases, B mild LCO [5-10] with 11, C moderate to severe LCO but alive[>10] with 8, D severe LCO to death with 4 cases. For the pleural effusion, group 1 was to be removed the chest tube within 1 week with 8 cases, group II within 3 weeks with 21 cases, group III beyond 3 weeks with 12 cases. We considered their age, diagnosis, pulmonary artery size[PA index], pulmonary artery abnormality, palliative shunt, systemic ventricular type, pulmonary artery wedge pressure, as preoperative factors, and operative methods, and as postoperative factors, CVP, LAP, arrhythmia, thrombosis, atrioventricular valvular insufficiency, etc. In the view of LCO, pulmonary artery size and PCWP were statistically significant [P<0.05], and arrhythmia, A-V valve insufficiency were inclined to the group C and D Pleural effusion was influenced by the pulmonary artery size, pulmonary artery resistance, PCWP, and CVP significantly. [P<0.05] And arrhythmia, residual shunt, and A-V valvular insufficiency were inclined to group II and III, too. As a results, the followings are to be reminded as the important factors at the care of post-Fontan LCO, and persistent pleural effusion [1] pulmonary artery size, [2] pulmonary artery resistance, [3] PCWP, [4] CVP, [5] arrhythmia, [6] residual shunt, [7]A-V valvular insufficiency.

  • Objectives : This study is designed in order to evaluate the therapeutic effect of Scalp Acupuncture and Do-ma Acupuncture related with Governer Vessel(Dok) and Bladder Meridian(Chok-taeyang) on acute low back pain Methods : We investigated 30 patients suffering from acute low back pain were admitted to Dunsan O.M.hospital from March. 1st 2005 to December. 30th 2005. We divided into two groups: one group was treated with Scalp acupunture, another group was treated with common acupuncture. 30 patients, were diagnosed only straightened curvature on lateral view of lumbar spine X -ray. Scalp acupunture related with Governer Vessel(Dok) and Bladder Meridian(Chok-taeyang) and Do-ma acupuncture. To estimate the efficacy of treatment that applied for two groups, we compared the visual analog scale(VAS), Oswestry disabiliby index(ODI) and Straight Leg Raising Test(SLRT) score of two groups statistically. Results : Both Scalp acupuncture related with Governer Vessel(Dok) and Bladder Meridian (Chok-taeyang) and Do-ma acupuncture therapy showed good effect on acute low back pain. It was proved by the difference between VAS, ODI and SLRT score checked before treatment and what checked after treatment on each groups. Conclusion: The therapeutic effect of Scalp Acupuncture and Do-ma Acupuncture on acute low back pain can be recommended as a useful therapy to treat acute low back pain.

  • BACKGROUND/OBJECTIVES: Increased consumption of instant noodles has recently been reported to be positively associated with obesity and cardiometabolic syndrome in South Korea, which has the highest per capita instant noodle consumption worldwide. This study aimed to investigate the association between instant noodle consumption and cardiometabolic risk factors among college students in Seoul. SUBJECTS/METHODS: The study subjects consisted of 3,397 college students (1,782 male; 1,615 female) aged 18-29 years who participated in a health checkup. Information on instant noodle consumption was obtained from the participants' answers to a question about their average frequency of instant noodle intake over the 1 year period prior to the survey. RESULTS: Statistical analysis using a general linear model that adjusted for age, body mass index, gender, family income, health-related behaviors, and other dietary factors important for cardiometabolic risk, showed a positive association between the frequency of instant noodle consumption and plasma triglyceride levels, diastolic blood pressure, and fasting blood glucose levels in all subjects. Compared to the group with the lowest frequency of instant noodle intake (${\leq}1/month$), the odds ratio for hypertriglyceridemia in the group with an intake of ${\geq}3/week$ was 2.639 [95% confidence interval (CI), 1.393-5.000] for all subjects, while it was 2.149 (95% CI, 1.045-4.419) and 5.992 (95% CI, 1.859-21.824) for male and female students, respectively. In female students, diastolic blood pressure was also higher among more frequent consumers of instant noodles. CONCLUSIONS: Our results suggest that frequent consumption of instant noodles may be associated with increased cardiometabolic risk factors among apparently healthy college students aged 18-29 years.

  • With recent advancements in the instrumentation and technique of VATS, it has become the method of choice to cure facial hyperhidrosis. From July 1996 to April 1997, we performed 43 thoracic lower stellate ganglionectomy with VATS for facial hyperhidrosis. There were 33 men and 10 women whose ages ranged from 17 to 63 years(mean age, 37 years). Of those patients, 23 complained only of facial hyperhidrosis, and 20 complained of facial hyperhidrosis along with excessive sweating of the palm or foot. Thoracoscopic sympathetic ganglionectomy procedures included lower stellate ganglionectomy in 12 patients; lower stellate ganglionectomy and T2-sympathetic ganglionectomy in 28 patients; and lower stellate, T2 and T3 sympathetic ganglionectomy in 3 patients. Common complications were compensatory hyperhidrosis(36 patients) and causalgia(8 patients). At the end of the follow-up period(minimum, 3 months) ninety-five percent of the patients reported satisfactory results. Thoracic lower stellate ganglionectomy with VATS is an efficient, safe and minimally invasive surgical procedure for facial hyperhidrosis.

  • Two hundred one patients of ventricular septal defect, which were operated at Seoul National University Hospital, were analysed on clinical background during the period from January, 1975 to December, 1980. The results were as follows: 1. Of the 201 patients, 118 patients were male [58.7%] and 83 patients were female [41.3%]. Their age ranged from 15 months to 40 years, and the mean age was 8.7 years. 40% of the patients were between 4 and 8 years. 2. The most common symptoms showed frequent U RI and exertional dyspnea. 3. On Kirklin`s anatomical classification, type I constituted 26.9%, type II 58.2%, type III 12.4%, and type IV 1.0%. We showed marked increased incidence of type I VSD as compared to Caucasians* 4. 46 cases were associated with other congenital cardiac diseases. They were PDA [13 cases], AI[11 ], ASD[6], PS[10], MI[4], and Double aortic arch [1]. 5. In 128 patients, who had complete hemodynamic data and were not associated with other congenital cardiac diseases, an attempt was made to correlate the EKG findings with the hemodynamic data, and defect size with the hemodynamic data. The children had variable distribution of PA syst. pr. and Rp/Rs. But most of adults had $R_P$/$R_S$of 0.15 or less. As $P_P$/$P_S$increased, the rate of operative complication increased also. 6. When a normal EKG pattern was present, $Q_P$/$Q_S$and $R_P$/$R_S$and $P_P$/$P_S$were relatively low. When EKG findings were LVH pattern, there was diastolic volume overload to left ventricle. As RVH, there was systolic pressure overload to right ventricle. And as BVH, there was mixed pattern of diastolic volume overload to left ventricle and systolic pressure overload to right ventricle. 7. Among patients in defect was less than 1 $cm^2$ per $M^2$ of BSA, $Q_P$/$Q_S$was less than 2:1, and $R_P$/$R_S$less than 0.25, and PAsyst. pr. less than 50 mmHg, and $P_P$/$P_S$was less than 0.5. But patients with the defect greater than 1 $cm^2$ per $M^2$ of BSA had no correlationship between $Q_P$/$Q_S$, $R_P$/$R_S$, PAsyst. pr. and defect size in each other. Most of patients with the defect greater than 2 $cm^2$/$M^2$ BSA, $R_P$/$R_S$was greater than 0.5. 8. Operative mortality rate was 9.5% [19 cases] among 201 patients. And complication rate including mortality rate was 22.9% [46 cases].

  • A clinical analysis was performed on 49 cases of the benign esophageal diseases experienced at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital during 7 year period from 1977 to 1983. Of 49 cases Of the benign esophageal diseases, there were 19 patients of esophageal stricture, 11 of achalasia, 6 of perforation, 3 of bronchoesophageal fistula, 3 of esophageal perforation, 3 of esophageal leiomyoma and one of esophageal foreign body. Twenty three patients were male and 26 were female. Ages ranged from 4 years to 74 years with the average age of 34.7 years. Of 19 patients of esophageal strictures, 7 patients were male and 12 were female and ages ranged from 6 years to 74 years with the average being 33.8 years. Causes of esophageal strictures were corrosive of esophageal strictures were dysphagia, vomiting, general weakness, weight loss and pain that order and developed on several different parts of esophagus. Operations were performed in 18 cases, of whom 7 patients were performed by esophagocologastrostomy, 4 gastrostomy, 4 esophagogastrostomy, 1 esophageal resection and esophagoesophagostomy, 1 esophagotomy and dilatation and 1 scar revision. Five patients had one or two complications; 2 anastomotic leakage, 1 wound infection, 1 localized empyema, 1 bilateral pneumothorax and 1 respiratory failure. One patient expired due to respiratory failure arising from aspiration pneumonia. The average age of achalasia patients was 33.1 years and symptom durations were from 2 months to 10 years with the average of 3.3 years. Main symptoms were dysphagia, vomiting, weight loss, pain and cough in that order. Modified Hellers myotomy was performed in 11 patients with one complication of restenosis. One patient was operated on by using longitudinal incision and transverse sutures with good result. Of 6 patient of esophageal diverticulum, 2 patients were traction diverticulum on the midesophagus, 2 were pulsion diverticulum on the midesophagus and 2 were pulsion diverticulum on the lower esophagus. Diverticulectomy was performed on 2 cases of traction diverticulum and esophagocardiomyotomy with or without diverticulectomy was erformed on 4 cases of pulsion diverticulum with good results. Of 5 patients of congenital bronchoesophageal fistula, the chief complaints were productive cough in 4 patients and hematemesis without respiratory symptoms in one patient. Two patients were operated on by using fistulectomy only and 3 by fistulectomy with pulmonary lobectomy. Of 3 patients of esophageal perforation, causes were foreign body ingestion, esophageal stricture after ECG and corrosive esophagitis. Two patient were operated on by using drainage and gastrostomy with symptomatic improvement but one patient died due to septic shock after thoracotomy. Three patients of esophageal leiomyoma were all male and 2 patients were operated on by using enucleation and one by distal esophagectomy with esophagogastrostomy. In one patient of esophageal foreign body, it was removed by esophagotomy through the right thoracotomy.
