Background & Object : Dyspepsia for which no organic causes are disclosed is referred to as functional dyspepsia. Functional dyspepsia is here studied in connection with a biopsychosocial model. From the aspect of individual response to external environment, in connection with stress response, functional dyspepsia is studied by both the psychology department and the internal medicine departments. The disease is taken as approachable from the aspect of internal injury due to seven emotions and stress as differentiated by Oriental medicine. Materials and Methods : Targeted at 223 patients underwent medical checks and endoscopy at Kangnam Korean Hospital, Kyunghee University. They agreed to join this clinical experiment. Stress response inventory, GARS (global assessment of recent stress scale), GSRS (gastrointestinal symptom rating scale), diagnostic scores for Ki-depression, and Spleen Disease Differentiation of Syndromes were all measured and evaluated. The test group was comprised of functional dyspepsia patients. The control group was comprised of nonsymptomatic chronic gastritis patients who were found to suffer from chronical gastritis in endoscopy and thus could be diagnosed with functional dyspepsia if symptoms would arise, but did not complain of subjective symptoms. Results showed these corelations: Functional dyspepsia patients were found to have more serious Ki-depression compared to nonsymptomatic chronic gastritis patients. The more serious Ki-depression the more serious the dyspepsia symptoms. The higher the stress response inventory the more serious the dyspepsia. Deficiency of spleen Eum, and Deficiency and Sinking of spleen Gi were found to coincide with serious Ki-depression.

Most of cosmetics are emulsion products that contain the source of nutrition-vegetable oil, mineral oil and carbohydrate etc. -so there is much possibility of contamination by microbials. The purpose of this study is to get the data necessary not only to prevent dermatopathia occurred by Escherichia coli but to sustain the quality and the wear of cosmetics as the result of finding optimum growth condition and the growth condition of Escherichia coli for enviro-factor, utilizing antiseptic so as to prevent contamination by observing it in emulsion type cosmetic. The results are as follows : 1. The optimum growth condition of Escherichia coli : pH7.0 and 37.5℃ The mixing volume ratio of water / oil was 70/30 in this experiment. 2. Adding antiseptics into emulsion type cosmetic, the number of Escherichia coli was decreased from 10^8(cell/ml) to 8 x 10^3(cell/ml) 3. Antibacterial effect against Escherichia coli was better as follows, p-hydroxy benzoic acid propyl ester + phosphoric acid buffer solution > p-hydroxy benzoic acid buthyl ester + acetic acid buffer solution > p-hydroxy benzoic methyl ester + phosphoric acid buffer solution > p-hydroxy benzoic acid methyl ester + p-hydroxy benzoic acid buthyl ester >p-hydroxy

Laparoscopic sleeve gastrectomy can reduce morbidity and mortality in patients with morbid obesity, but it can cause complications such as a gastrointestinal leak. A 30-year-old morbidly obese female who had type 2 diabetes mellitus and hypertension with estimated body mass index of 40.2 kg/m2 was admitted. Laparoscopic sleeve gastrectomy was performed. On postoperative day 19, a leak was suspicious on physical examination and radiologic findings. Conservative management was performed, but the patient was hemodynamically unstable and imminently septic. After laparoscopic drainage procedure, esophagogastroduodenoscopy was performed and revealed the fistula opening at staple line just below gastroesophageal junction. Fibrin tissue adhesive was injected around the fistula and the esophageal covered stent was inserted to cover the leak. At 14th days after stent insertion, the barium study confirmed no more leak. In this case, we experienced that the esophageal stent insertion with fibrin tissue adhesive injection may reduce recovery time of the fistula developed after laparoscopic sleeve gastrectomy

진행파와 상호상관함수를 이용한 HVDC 케이블 고장점 표정 알고리즘

For a safe operation of HVDC systems, the fault location and clearance of faults in the HVDC cables are important. In the past, search coil method and murray loop methods are mainly used for the fault location. But the results of these methods depend On existence of assistance cables and fault resistance and broken cables. The environment of fault location also affects the result of the fault location. To complement these problems, in this paper, fault location method using traveling wave and cross correlation is proposed for HVDC cable faults. In other words, the times those are the instants of the first incident and the second incident are found by using cross correlation. And fault location is calculated by using the difference time of two incidents and a velocity of the traveling wave. For case study, HVDC cable system modeling is accomplished by EMTDC/PSCAD and the algorithms are developed by using Matlab V7.1 and microsoft visual C++. To acquisite the fault data, IEC 61850 based IEDs are constructed. In this system, the proposed algorithm is implemented and verified by using the fault data that can be acquisited from IEC 61850 based IED.

<P>Concurrent chemotherapy with radiotherapy (CCRT) has been applied for the treatment of advanced stage of head and neck cancer patients. However CCRT is associated with several complications including mucositis, dermatitis, stomatitis, etc. This study was conducted to evaluate the therapeutic effect of systemically administrated recombinant human epidermal growth factor (rhEGF) in CCRT-induced oral mucositis in a mouse model. Oral mucositis was induced in male BALB/c mice through combination treatment with cisplatin (11 mg/kg, i.p.) and irradiation (17 Gy) of the head and neck area. rhEGF (1.0 mg/kg/day for consecutive 3 days) was administered systemically, and the therapeutic effect was determined by histological evaluation of the oral mucosa. To elucidate optimal dose of rhEGF on CCRT-induced mucositis, various concentrations (0.04–3 mg/kg) of rhEGF were injected for 3 days. Systemic rhEGF administration accelerated the recovery of body weight. Histologically, rhEGF-treated mice showed significantly increased epithelial cell layer thickness, basal cell number, and expression of Ki-67 compared to control mice. Most effective dose was 1 mg/kg among other doses tested. Systemic administration of 1 mg/kg of rhEGF reduces the severity of oral mucositis induced by CCRT in a mouse model, suggesting that rhEGF can be used for treating CCRT-induced mucositis during the cancer treatment.</P>

The purpose of this study was to investigate the influence of light irradiation over self-priming adhesive on dentin bonding. After acid etching the exposed dentin, a self-priming adhesive (Prime&Bond□NT dental adhesive system, Dentsply DeTrey, GmbH, Konstanz, Germany) was applied and light irradiation was done for 20 sec with regular intensity (600 mW/㎠) in group I and for 3 sec with ultra-high intensity (1930 mW/㎠) in group III. No light irradiation was done over self-priming adhesive in groups II and IV. Composite resin was added on the self-priming adhesive and irradiated for 40 sec with regular intensity (600 mW/㎠) in groups I and II and for 3 sec with ultra-high intensity (1930 mW/㎠) in groups III and IV. To see the effect of light curing time on dentin bonding, another 3 group specimens were prepared. Without light-irradiation over self-priming adhesive, added composite resin was irradiated for 3, 6, or 12 sec with ultra-high intensity light. After bonded specimens were stored in 37℃ distilled water for 24 hours, shear bond strength were measured using a universal testing machine (4202, Instron, Instron Co., U.S.A.) and fractured surfaces were examined under a stereomicroscope (SZ-PT Olympus, Japan) . Statistical analysis were done with one-way, two-way ANOVA and chi-square test. The results were as follows: 1.The shear bond strengths from the groups irradiated over self-priming adhesive were significantly higher than those from the groups without irradiation (p<0.05). 2.There was no significant shear bond strength difference between regular intensity light irradiation groups and ultra-high intensity ones (p>0.05). 3. There was no significant shear bond strength difference among various irradiation time groups with ultra-high intensity ones (p>0.05). 4.In stereomicroscopic examination of fractured surfaces, adhesive-cohesive mixed failure mode was mostly seen in all groups, and there was no significant difference in failure mode among groups (p>0.05) . Key words : Light irradiation, Self-priming adhesive, Dentin bonding, Shear bond strength

The authors analyzed retrospectively the 60 patients with ameloblastoma who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from MArch, 1990 to December, 1995. The results obtained were as follows: There were 26 males (43.3%) and 34 females (56.7%). The peak age of patients was the third decade (41.7%). The majority of cases occurred in the mandible 93.3%, especially in the angle region (91.1%). Eighteen of 60 patients (30.0%) were associated with an impacted tooth, by impacted 3rd molar teeth (16.6%), molar (10.0%), and premolar and canine (3.4%) in order., Fifteen of 60 patients (25%) were associated with an odontogenic cyst, by dentigenous cyst(13.3%), odontogenic keratocyst(8.4%), and radicular cyst(3.3%) in order. Radiographically, there were 32 unilocular types(54.2%) with average age of 24.9±10.8 years, 14 multilocular types(23.7%) with average age of 35.7±17.7 and 13 mixed types(22.0%) with average age of 41.4±15.8. Histopathologically, there were 42 follicular types(70.0%) with average age of 33.7±15.1 years and 18 plexiform types(30.0%) with average age of 26±14.6. Conservertive treatment was performed in the 33 patients(55.0%) and their average age was 25.2±13.9 years and radical treatment in the 27 patients(45.0%) and their average age was 39.3±41.8. Overall recurrence rate was 10%. A consistent correlation between the age of the patient and the radiographic or histologic type of mandibular ameloblastoma was observed. There was a tendency for ameloblastomas of the follicular type to show a multilocular or mixed appearance and for those of the plexiform type to show a unilocular appearance.
