FMS(Flexible Manufacturing System) scheduling problem is a complex system and a NP-hard problem. Thus it is natural to look for heuristic method. Here, we consider the multi-part production scheduling problem in a FMS scheduring of altemative routings. The problem in more complex if the processing time is imprecision. It requires suitable method to deal with imprecision. Fuzzy set theory can be useful in modeling and solving scheduling problems with uncertain processing times. Lee-Ki fuzzy number comparison method will be used to compare processing times that evaluated under fuzziness. This study propose heuristic algorithm solving FMS scheduling problem under fuzzy environment. In this algorithm, the pairwise comparision method is used to find proper alternative routing. On the basis of the proposed method, and example in presented.

Most commonly and widely used diagnostic tool for chronic paranasal sinusitis in children is plain X-ray check not only because of small radiation dose and easy performance, but because of low cost. However ostiomeatal unit computed tomography(OMU CT) was known to be more accurate and recommended recently by many physicians. The author have studied for both OMU CT and plain X-ray of paranasal sinuses and compaird their findings in 90 chidren(180 sides of sinus) aged from 4 to 14 years who suspected having sinusitis. OMU CT was taken after plain X-ray examination (Caldwell's view, water's view, lateral view), and the time interval betweeen these two examination was O to 14 days (average 4.7 days). The following results were obtained. Considering that OMU CT was accurate, the rate of correspondence in diagnosis of sinus pathology between plain X-ray and OMU CT was 48.3% in the ethmoid sinus, 51.1% in the maxillary sinus, 41.9% in the sphenoid sinus, 43.4% in the frontal sinus. If all OMU CT findings had been accurate, the incidence of false positives according to plain X-ray was 25.5% in the ethmoid sinus, 28.3% in the maxillary sinus, 70.8% in the spenoid sinus and 77.8% in the frontal sinus. While, the incidence of false negatives according to plain X-ray was 85.9% in the ethmoid sinus, 70.5% in the maxillary sinus, 50.0% in sphenoid sinus and 37.5% in the frontal sinus. A routine preoperative OMU CT is recommended, which allows a detailed evaluation of pathologic changes and anatomical relations of the paranasal sinuses before surgical interventiaon for the paranasal sinuses. Considering the above facts, diagnosis of pediatric sinusitis only by plain X-ray was inadequate and OMU CT was necessary.

Otitis media with effusion (OME) is one of the most common disease in children but its pathogenesis is not clear. In particular the role of allergy has revealed conflicting support with widely varing opinions as to its importance. Within recent years, striking biochemical and immunochemical analytic techniques have opened a new approach the study of otitis media with effusion. So we focused on distributions of IgE in adenoid tissue and serum IgE levels. Authors compared the serum IgE and the distribution of IgE in adenoid tissue between the 20 patients underwent tonsillectomy, adenoidectomy and ventilating tube insertion and control group of 11 patients underwent tonsillectomy and adenoidectomy. The results were as follows; 1. In the distribution of IgE in adenoid tissue, there was a significant increase in the group of patients with OME compared to the control group (P<0.01). 2. In the analysis of serum IgE levels, the levels of IgE in the OME patients an control group were higher than normal level, although the level of IgE in the OME patients were less than that of control group, there was no significance P>0.05).

장주호,김수한,정신,김재휴,강삼석,이제혁 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.4

The authors report clinical results of twenty-three traumatic thoracolumbar burst fractures treated by internal fixation with Kaneda device after anterior decompression during recent three years. Thoracolumbar injuries made up 28.9% of total spinal injuries and the burst fractures treated by anterior decompression and stabilization with Kaneda device constituted 19.0% of all spinal injuries. The burst fractures occurred most frequently at the age of twenties and thirties. The main causes of injury were fall and vehicle accident. Superior end-plate fracture type was most common according to the types of burst fracture. The first and the second lumbar vertebrae were frequently involved. No patient showed neurological deterioration after surgery. Conus medullaris lesions in burst fractures of the thoracolumbar junction have a high potentiality for functional recovery because the lesions are not due to discontinuity or severe crush injury but due to simple compression by bony fragments. The Kaneda device offered enough stability to enable early ambulation with good alignment and solid fusion.

Objectives: The purpose of this study was to observe the reaction kinetics and the degree of polymerization of composite resins when cured by different light sources and to evaluate the effectiveness of the blue Light Emitting Diode Light Curing Units (LED LCUs) compared with conventional halogen LGUs. Materials and Methods: First, thermal analysis was performed by a differential scanning calorimeter(DSC). The LED LCU (Elipar Freelight, 320㎽/㎠) and the conventional halogen LCU (XL3000, 400㎽/㎠) were used in this study for curing three composite resins (SureFil, Z-250 and AEliteFLO). Second, the degree of conversion was obtained in the composite resins cured according to the above curing mode with a FTIR. Third, the measurements of depth of cure were carried out in accordance with ISO 4049 standards. Statistical analysis was performed by two-way ANOVA test at 95% levels of confidence and Duncan's procedure for multiple comparisons. Results: The heat of cure was not statistically different among the LCUs (p > 0.05). The composites cured by the LED (Exp) LCUs were statistically more slowly polymerized than by the halogen LCU and the LED (Std) LCU (p< 0.05). The composite resin groups cured by the LED (Exp) LGUs had significantly greater degree of conversion value than by the halogen LCU and the LED (Std) LCU (p = 0.0002). The composite resin groups cured by the LED (Std) LGUs showed significantly greater depth of cure value than by the halogen LCU and the LED (Exp) LGU (p < 0.05).

Hypertension is one of the major risk factor for cardiovascular disease and can lead to or make worse many complications, heart disease, atherosclerosis and diabetes. Thus, managing blood pressure effec tively using therapeutic drugs such as angiotensin II receptor blocker (ARB) and Ca2+ channel blocker (CCB) can be prevent other complications. Therefore, we investigated the synergistic effect of these two drugs, ir besartan and lercanidipine, for antihypertension, cardioprotection and antidiabetes. Irbesartan (28.74 mg/kg, 14.37 mg/kg) or lercanidipine (1.92 mg/kg, 0.96 mg/kg) alone or combination was administered to sponta-neously hypertensive rats (SHRs) and C57BL/6 mice. A two-week treatment of combination with irbesartan and lercanidipine significantly attenuated systolic blood pressure (SBP) and mean arterial pressure (MAP) compared with monotherapy. Futhermore. the combination therapy protected myocardial ischemia reperfusion injury more effectively than monotherapy. In vascular remodeling, combination therapy significantly diminished cuff -induced neointima formation and reduced serum -indllced vascular smooth muscle cells (VSMCs) pro-liferation compared with monotherapy. However, combination therapy had no significant synergistic effect of blood glucose regulation. Taken together, present study suggest that the combination therapy of irbesartan and lercanidipine may be more effective therapeutic strategy for the treatment of hypertension and related complications, myocardial infarction and arterial restenosis than monotherapy

Objectives: Insampaedok-san and its main components have been used for treatment of fever, joint pain, cough, headache and pain. Using a respiratory inflammation model, we intend to investigate the anti-inflammatory effect and its mechanism of Insampaedok-san. Methods: We induced the actue respiratory inflammatory mouse model by papain treatment. BALB/C mice (female, 8 weeks old) were divided into three groups as follows: saline control (SC): papain treated group (vehicle): papain and Insampaedok-san (200mg/kg) treated group (n=4). To demonstrate the ani-inflammatory effect of Insampaedok-san water extracts, inflammatory cell infiltration was evaluated in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). In addition, immunogloblin (Ig)-E level was measured by using ELISA. Results: Insampaedok-san extracts administration decreased inflammatory cell infiltration in BALF and NALF. Especially, eosinophil infiltration was dramatically reduced. Furthermore, total Ig-E level was diminished in BALF and serum by Insampaedok-san administration. Conclusions: Our findings revealed Insampaedok-san extracts have anti-inflammatory effects by inhibiting inflammatory cell, especially eosinophil infiltration and Ig-E level.
