Purpose : This study aims to suggest application of patients DB to hospital marketing by performing market segmentation and selecting target market. Consequently help to establish suited strategy of marketing. Method : 14,072 patients hospitalized in a University Medical Center were recruited into this study. In order to classify the customer groups, cluster analysis was used with RFM(Recency, Frequency, Monetary) model, and 1-way ANOVA verified the differences among groups. And then, sociodemographical status, healthcare utilization and diagnosis(ICD-10) of each group were compared to draw a marketing strategy. Results : Four groups were classified through clustering analysis, and'high use and high profit' and'low use and high profit' groups were selected as a target market. The features of target market were as follows, the female proportion was high; used a private room; hospitalized through the emergency room; had operation; length of stay was long; had many comorbidity and cooperative treatment. There was difference in each feature of target market: as for the'high use and high profit' group, many patients were diagnosed with 'certain infectious and parasitic diseases'; and as for the'low use and high profit'group, the proportion of patients who purchased'industrial accident compensation insurance'and'auto insurance'was relatively high; many patients were diagnosed with'Injury, poisoning and certain other consequences of external causes'. Conclusion : It is needed to establish'positioning' strategy by monitoring and communicating with'high use and high profit' group. And for the case of'low use and high profit' group, it is necessary to make a follow-up management and lead them to have a medical check-up.

Objectives : This study was designed to evaluate various tools including C-spine X-ray for estimating cervical curvature and identify the effect of wooden pillow on patients diagnosed with straightening of cervical curvature. Methods : This study was carried out on 51 subjects who were encountered traffic accident suffering cervical pain and diagnosed with straightening of cervical curvature by X-ray. 51 subjects were divided into wooden pillow(experimental) group and conservative therapy(control) group. Visual analogue scale, neck disability index and lateral pictures were used and compared after treatment. C-spine AP., Lat. X-ray were used on admission day to calculate cervical curvature and scoliosis by various ways. Results : 4 different measurements of cervical curvature didn't show common results. Both wooden pillow(experimental) group and conservative therapy(control) group showed significant improvement in the visual analogue scale(VAS) and neck disability index(NDI) after hospital treatment. Comparison between center line pictured by lateral view and C-spine Lat. pictured by X-ray showed significant difference in cervical curvature. Lateral deviation of cervical vertebra showed lengthened distance between mastoid process and spinous process of C7. Conclusion : As a result of this research, I found out that various tools for calculating cervical lordosis could derive different results and C-spine AP., Lat X-ray could cause artificial cervical lordosis. According to visual analogue scale(VAS) and neck disability index(NDI) wooden pillow was not effective to reduce pain & disability caused by straightening of cervical curvature. Futhermore, correction effect of straightening of cervical curvature and scoliosis by wooden pillow was weak.

This study was aimed at furnishing the data of Naso-orbito-ethmoidal fractures and aiding treatmenting Naso-orbito-ethmoidal fractures A 5-year review of Naso-orbito-ethmoidal fractures and concomitant injuries is presented. The patients were treated in the Dept. of Oral and Maxillofacial Surgery of Wankwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The results were as followes: Male predominated over female by a ratio of 4.6 : 1. The most common reasons is traffic accident(88.2%). The elapsed time from injury to operation is average 9.2 days, and the mean admission days were 79 days and removal of plates were average 217.3 days. The most associated facial bone fractures is Zygomatico-Maxillary complex fracture(20%). Associated injuries were neurologic injury(29.4%), orthopedic injury(23.5%), opthalmologic injury(17.6%), body injury(5.8%), neuropsychologic injury(5.8%) and otolaryngologic injury(5.8%) in this order. The most injured teeth were upper and lower incisors. The intubation methods for surgery were orotracheal(29.57%), submental(29.5%), and nasotracheal technique(41%). Most patients had complications, that were post-traumatic telecanthus, nasal depression, scar formation. This results suggest that early diagnosis and treatment is prerequisits to satisfactory result. Aggressive management of NOE fracture with direct or bicoronal exposure with aid of CT is now an accepted norm.

Purposes: Pancreatic injury is rare in abdominal trauma patients (3%~12%). but it could result in significant morbidity and even mortality. Early and adequate decision making are very important in the management of patients with traumatic pancreatic injury. The purpose of this study was to assess the kinds of management and outcome through the review of our experience of pancreatic injury with multiple trauma. Methods: We reviewed 17 patients with traumatic pancreas injury via electronic medical records from Jan. 2002 and April. 2011. We collected demographic findings; the type, location and grade of pancreas injury, the treatment modality, and patient's outcomes, such as complications, length of hospital stay (LOS), and mortality. Results: Total 17 patients were reviewed, and man was 13 (88%). Traffic accident was the most common cause of injury. Pancreas neck was the most common injured site, and occured in 5 patients. Ductal injury was detected in 7 cases. Eleven patients were treated by surgical procedure, and in this group, 3 patients underwent the endoscopic retrograde pancreas drainage procedure coincidently. ERPD was tried in 8 patients, and failed in 2 patients. The major complications were post-traumatic fluid collection and abscess which accounted for 70 % of all patients. The hospital stay was 35.9 days, and it was longer in patient with ductal injury ($38.0{\pm}18.56$ vs. $34.5{\pm}33.68$ days). Only one patient was died due to septic shock associated with an uncontrolled retroperitoneal abscess. Conclusion: Early diagnosis is the most important factor to apply the adequate treatment option and to manage the traumatic pancreas injury. Aggressive treatment should be considered in patients with a post-operative abscess.

Five cases of esophageal cancer developed at the site of esophageal lye stricture were reported. Duration of lye stricture was between 13 and 40years, and all 5 cases had taken normal diet without appreciable troubles after recovery from the acute stage of burn till the suspected onset of esophageal malignaney. Outstanding symptoms of this grave condition were rather acute progressive dysphagia and frequent episodes of esophageal foreign bodies, Diagnosis could be confirmed easily by endoscopic biopsy in suspected eases, and all were epidermoid carcinoma histopathologically. Curative resection of this condition was made in neither of the cases, and their prognoses were more grave than other esophageal malignancies in our experience. The development of esophageal carcinoma at the site of corrosive esophagitis with resulting benign stricture has now been suspected as a cause and effect relationship between these two conditions, and Kiviranta: stated that the incidence of esophageal cancer in patients with lye stricture of longer duration is a thousand times higher than normal population. During last one decade the authors experienced 5 cases of esophageal carcinoma developed at the site of lye stricture of the esophagus among about 350 cases of lye burned esophagus at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul, Korea. In Korea they still use lye as a detergent in rural area, and there are still many persons ingesting lye for suicidal attempt or on accident. Lye stricture of the esophagus is, therefore, the most common esophageal disease needing surgical procedures, and the authors believe that there will be much more eases of lye stricture complicated by esophageal eareinoma repoted in near future in this Country.

The records of 14 patients with traumatic diaphragmatic rupture seen at Dongguk University Hospital from February 1992 through December 1995 were reviewed. Ten patients were male and four were female(M:F=2.5:1). The age distribution ranged from 17 to 73 years with the mean age of 41.7 years. The 14 patients included 12 who had blunt trauma(traffic accident 11, crushing injury 1) and 2 with penetrating diaphragmatic rupture(stab wound 2). Of those 12 blunt trauma, 7 patients(58.3%) were left sided and 5(41.7%) involved the right hemidiaphragm. The diagnosis was made preoperatively in 8 patients (57.1%) and during surgery in 6(42.9%). All right-sided injuries were repaired through a thoracotomy and left-sided defects were corrected through a laparotomy in 6, laparotomy and thoracotomy in 1. There were 2(14.3%) operative deaths that were caused by myocardial infarction and the sequelae of combined injuries.

Local wall thinning and integrity degradation caused by several mechanisms, such as flow accelerated corrosion (FAC), cavitation, flashing and/or liquid drop impingements, are a main concern in carbon steel piping systems of nuclear power plant in terms of safety and operability. Thinned pipe management program (TPMP) had been developed and optimized to reduce the possibility of unplanned shutdown and/or power reduction due to pipe failure caused by wall thinning in the secondary side piping system. This program also consists of several technical elements such as prediction of wear rate for each component, prioritization of components for inspection, thickness measurement, calculation of actual wear and wear rate for each component. Decision making is associated with replacement or continuous service for thinned pipe components. Establishment of long-term strategy based on diagnosis of plant condition regarding overall wall thinning is also essential part of the program. Prediction models of wall thinning caused by FAC had been established for 24 operating nuclear plants. Long term strategies to manage the thinned pipe component were prepared and applied to each unit, which was reflecting plant specific design, operation, and inspection history, so that the structural integrity of piping system can be maintained. An alternative integrity assessment criterion and a computer program for thinned piping items were developed for the first time in the world, which was directly applicable to the secondary piping system of nuclear power plant. The thinned pipe management program is applied to all domestic nuclear power plants as a standard procedure form so that it contributes to preventing an accident caused by FAC.
